Description

  The present invention relates to a surface property inspection apparatus and method for inspecting the surface property of a cylindrical part, and more particularly to the surface property of the product including the presence or absence of surface flaws in a cylindrical metal rod. The present invention relates to a surface property inspection apparatus and method that can be inspected efficiently and at low cost.

  2. Description of the Related Art Conventionally, for example, metal parts made of a metal linear body or metal rod body having a predetermined length and diameter (hereinafter simply referred to as a rod body) have been produced by various methods in the metal part industry and widely used in various applications. in use.

  However, when such metal rods are produced, defects such as cracks, grooves and scratches may occur on the surface of the metal rods due to factors in various manufacturing processes. For this reason, it is necessary for a manufacturer who manufactures the part to inspect each product for the above-described scratches before shipment before shipping.

  However, according to the conventional practice, the above-mentioned scratches are inspected only by the steel manufacturers that manufacture the wire or steel that is the raw material of those products, and the component manufacturers do not inspect the above-mentioned defects themselves. It was not common.

  However, in recent years, manufacturers of the metal parts have been increasingly required to inspect for defects in all the products manufactured by the manufacturer, and an inspection device for that purpose has become necessary. .

  By the way, in the past, as a quality control method for the metal parts to be produced, for example, although the dimension management is standardized for inspection using an automatic measuring device, the above-described scratches, etc. With regard to these defects, most of them are currently performed by human visual inspection.

  For this reason, there are many individual differences, time differences, and standard variations in quality control, and there are many occurrences of missing defects. Complaints are generated after the product is shipped, and it is required to re-examine all products again. Things are becoming more and more common, and the time, labor, and expenses for that purpose are increasing, leading to increased costs.

  On the other hand, as the rod body, as an example, when considering the manufacture of a Migaki round bar material (reference dimensions φ3 to 30 mm, many sizes of about 0.5 to 6 m), which is a general secondary processed product, The manufacturing process is generally composed of a rolling process, a drawing process, a wire drawing process, a cutting process, a stamping process or a polishing process, and the final product is obtained through each of the above processes.

  Therefore, if it is a wire rod or steel material maker, individually arrange a visual inspection device or an automated inspection device for inspecting whether there is a scratch on the surface of the rod body during each process, The bar body is inspected for the presence or absence of surface flaws for each lot of the bar body product or as necessary.

  However, the conventional surface flaw inspection apparatus is specially manufactured for the surface flaw detection of the rod body. Therefore, the surface flaw inspection apparatus itself is referred to as an inspection rod body (hereinafter simply referred to as a subject). ) And a rotating mechanism for rotating the flaw detection sensor itself around the rod, and as a result, the surface flaw inspection device. As a result, the space for placing the surface flaw inspection apparatus is required to be large.

  Further, when a conventional surface flaw inspection apparatus is used, for example, when performing a surface flaw inspection of a rod manufactured in a predetermined process, the subject is temporarily stored in a predetermined place, According to the schedule, it is common to carry the inspection to the surface flaw inspection apparatus and execute the inspection. Therefore, when inspecting the surface flaw of the rod, the storage space for the subject and the storage A means for transporting the subject to the space and a means for transporting the subject from the storage space to the surface flaw inspection apparatus are required, and at the same time, a waiting time is required to temporarily stop the flow of the subject. As a result, there is a problem that the manufacturing process of the rod body becomes long and complicated due to the necessity of a special transport line and storage space in the manufacturing process of the rod body, and at the same time, the cost is greatly increased.

Furthermore, in order to pass the subject through an extra transport section, there is also a problem that the subject is damaged during transport.
This situation is the same for the finishing manufacturer of the rod body.

  By the way, the conventional rotary type surface flaw automatic inspection device uses the eddy current test method and the leakage magnetic flux flaw detection test method, both of which have a mechanism that rotates a flaw detection rotary head with a sensor attached to the inner surface at high speed. The entire circle of the rotating circle is inspected for scratches by moving it straight so that the round bar, which is the object to be inspected, penetrates the cavity of the center of the rotating circle. However, it is installed in the large-scale steel industry, etc., but the equipment burden is considerably large for a secondary processing manufacturer with a smaller production volume.

However, the market tends to increase the burden of product inspection as customers increasingly request full inspection.
On the other hand, as a method for detecting an internal defect or a surface defect of the metal product, Japanese Patent Laid-Open No. 58-49822 (
) As shown in the figure, when a coil is wound around a metal part under test or when a high frequency current is passed through the coil when the coil is placed in close proximity, an eddy current is generated and the impedance of the coil due to the eddy current is detected. Thus, an eddy current flaw detection method for determining whether or not a metal part under test has a flaw has been put into practical use.

Such an eddy current flaw detection method is disclosed in JP-A-7-229872 (
), Japanese Patent Laid-Open No. 11-352109 ( ) And JP-A-7-294495 ( ), Which is mainly used for inspection of long metal wires or steel materials, and the eddy current inspection method is used for inspection of defects for individual metal parts. Is not shown in either.

JP-A-9-80028 (
) Discloses a surface flaw detection apparatus for metal products that want to use eddy currents, but also in this known example, the surface flaw inspection apparatus is arranged between a finishing rolling mill and a water cooling apparatus. Alternatively, it only shows the technology that is configured to continuously inspect the presence or absence of surface flaws in rolled steel, with regard to the technology that individually inspects the surface flaws of metal bars after individual finish processing. There is no disclosure.

  However, recently, due to the above-mentioned social demand, a flaw inspection apparatus for inspecting the presence / absence of the above-mentioned defect of a metal part using the above-described eddy current flaw detection method has been developed. This inspection device is designed to be used only for the inspection of parts with a specific shape, so it is not versatile, and the individual inspection devices are expensive. This is the current situation.

  The above-mentioned problems are not limited to metal parts having a cylindrical shape, but are made of plastic or rubber cylindrical members, glass or ceramic cylindrical members, Cylindrical members made of wood, cork, paper, fiber materials, etc. Furthermore, cylindrical members made of composite materials made of the above materials have the same problems for industrially diverse members. The surface characteristics of such a member, such as surface cracks, scratches, unevenness, surface friction coefficient, degree of wear, unevenness of the thickness of the coated film and its defects, as well as its peeled state or specific pattern The presence or absence is frequently inspected. Therefore, it is highly versatile, low cost, easy to operate, and high speed can be expected. It can inspect the surface characteristics of cylindrical shaped parts, a surface characteristic inspection apparatus smaller cylindrical part of the occupied area has been strongly desired in the industry.

  In other words, in the conventional technology, cylindrical parts, for example, metal parts such as shafts and pins, are widely used in the world, but for parts used for important applications such as mechanical parts, quality inspection The visual inspection is mainly performed by visual inspection.

  In some cases, there is an automatic inspection device by mechanization, but in order to inspect the entire outer periphery, a mechanism for rotating the part to be inspected and a mechanism for scanning the detection sensor are required, and the equipment is complicated and expensive. The problem was that the size of the equipment was large and the processing capacity was low, and it was necessary to solve the problem.

  Accordingly, an object of the present invention is an inspection apparatus that improves the above-described problems of the prior art, has a simple structure for the surface characteristics of cylindrical parts, can be inspected efficiently and with high accuracy, and is versatile. Therefore, the present invention provides a low-priced, low-cost cylindrical part surface property inspection apparatus.

  In order to achieve the above object, the present invention employs a basic technical configuration as shown below. That is, as a first aspect of the present invention, basically, at least one cylindrical driving rotary roller for mounting a cylindrical part to be inspected on its surface and rotating it in a predetermined direction and the driving rotary roller. Cylindrical shape composed of surface characteristic inspection means for the cylindrical part to be inspected for inspecting the surface characteristic of the cylindrical part to be inspected arranged close to the surface of the cylindrical part to be inspected rotated above In the surface property inspection apparatus for a part, a cylindrical part moving mechanism to be inspected is provided that moves the cylindrical part to be inspected in a predetermined direction while moving the cylindrical part in a rotational axis direction of the cylindrical part to be inspected. An apparatus for inspecting the surface characteristics of a cylindrical part, and as a second aspect of the present invention, basically, a cylindrical part to be inspected is mounted on the surface and rotated in a predetermined direction. A cylindrical shape to be inspected that inspects the surface characteristics of the cylindrical part to be inspected that is arranged in the vicinity of the surface of the cylindrical part to be inspected that is rotated on one cylindrical driving rotary roller and the driving rotary roller. In a surface characteristic inspection apparatus for a cylindrical part composed of a surface characteristic inspection means for a part, while rotating the cylindrical part to be inspected in a predetermined direction, in the rotation axis direction of the cylindrical part to be inspected. A method for inspecting the surface characteristics of a cylindrical part characterized by continuously inspecting the surface characteristic of the cylindrical part to be inspected over a predetermined surface area by moving it.

  Since the surface characteristic inspection apparatus for cylindrical parts according to the present invention employs the above-described technical configuration, the various surface characteristics of the cylindrical part to be inspected have a simple configuration, efficiently, and Provided is a low-cost surface property inspection device that can be inspected with high accuracy and is versatile. Further, a cylinder that can easily and highly accurately inspect the surface properties of the cylindrical part. A method for inspecting the surface characteristics of a shaped part is provided.

  Hereinafter, the configuration of a specific example in the surface characteristic inspection apparatus for a cylindrical part according to the present invention will be described in detail with reference to the drawings.

  That is, FIG. 1 is a view showing the structure of a specific example of a surface characteristic inspection apparatus 1 for a cylindrical part according to the present invention. In FIG. At least one cylindrical drive rotating roller 3, 3 ′ rotated in the direction and the cylinder to be inspected arranged close to the surface of the cylindrical part 2 to be inspected rotated on the drive rotating roller 3, 3 ′ In a surface property inspection apparatus 1 for a cylindrical part composed of surface characteristic inspection means 4 for inspecting the surface characteristic of a shaped part, the cylindrical part 2 to be inspected is rotated in a predetermined direction while the object to be inspected is rotated. 1 shows a cylindrical part surface characteristic inspection apparatus 1 provided with a to-be-inspected cylindrical part moving mechanism 5 for moving the inspection cylindrical part in the rotational axis direction.

  By the way, the to-be-inspected cylindrical part 2 used in the present invention is composed of any one of metal, synthetic resin, glass, ceramic, wood, cork, paper, fiber material, and composite materials thereof. All the objects are objects, and the use of the inspected cylindrical part 2 is not particularly limited.

  Further, the cylindrical part 2 to be inspected can have any shape as long as it has a cylindrical shape, and the diameter and the longitudinal direction, that is, the length in the direction of the rotation axis, etc., are of arbitrary dimensions. It is possible.

  Therefore, in order to achieve the object of the present invention, the surface characteristic inspection apparatus for the cylindrical part needs to have an open type structure. Therefore, the surface characteristic inspection for the cylindrical part in the present invention is required. The apparatus 1 is an open type so that the cylindrical part 2 to be inspected having all dimensions can be easily and arbitrarily inserted into the surface characteristic inspection apparatus 1 of the cylindrical part and can be easily discharged after the inspection is completed. The structure is adopted.

  And in order to implement | achieve the objective of the above-mentioned this invention, it is necessary to measure the whole outer peripheral surface of the said to-be-inspected cylindrical component 2, and the said surface characteristic test | inspection means 4 or while maintaining a fixed measurement effective distance It is necessary to move the cylindrical part 2 to be inspected and scan the entire predetermined area of the cylindrical part 2 to be inspected two-dimensionally.

  Therefore, in one specific example of the present invention, as shown in FIG. 1, the surface characteristic inspection means 4 is fixed, and the measurement between the surface characteristic inspection means 4 and the cylindrical part 2 to be inspected is performed. In order to measure the entire outer peripheral surface of the cylindrical part 2 to be inspected while keeping the effective distance constant, a pair of two cylinders installed close to each other in parallel and rotating in the same direction. Cylindrical driving rotary rollers 3 and 3 ′ are used, and the cylindrical part 2 to be inspected is formed in a groove-like portion 6 formed by the pair of cylindrical driving rotary rollers 3 and 3 ′ arranged in proximity to each other. The cylindrical part 2 to be inspected is thereby rotated in a direction opposite to the rotational direction of the cylindrical driving rotary rollers 3 and 3 ′.

  In other words, in one specific example of the present invention, the cylindrical part 2 to be inspected is one of the two cylindrical driving rotary rollers 3 and 3 ′ arranged close to each other. It is desirable to be able to contact and rotate these surfaces simultaneously.

  Each of the cylindrical driving rotary rollers 3, 3 'is rotated in the same direction at the same speed by one or two motors 19-1, 19-2 provided as appropriate.

  At this time, as shown in FIG. 1, the rotation axis O1 of the cylindrical drive rotation roller 3 and the rotation axis O2 of the cylindrical drive rotation roller 3 ′ have the same inter-axis distance, and also in the horizontal and vertical directions. In addition, when arranged in a state of being completely parallel to each other, the rotation axis P of the cylindrical part 2 to be inspected is also connected to the rotation axes O1 and O2 of the cylindrical drive rotation rollers 3 and 3 ′. Since they are parallel, the cylindrical part 2 to be inspected rotates at a position placed on the cylindrical driving rotary rollers 3 and 3 ′.

  In the present invention, in this aspect, it is necessary for the cylindrical part 2 to be inspected to move in the direction of the rotation axis P of the cylindrical part 2 to be inspected. In this case, the cylindrical part moving mechanism to be inspected enables the surface characteristic inspection apparatus 1 for the cylindrical part to move the inspected cylindrical part 2 in the direction of the rotation axis P of the inspected cylindrical part 2. 5 is provided.

  As an example, the cylindrical part moving mechanism 5 to be inspected in the present invention is such that at least one of the rotation shafts O1 or O2 of the cylindrical driving rotary rollers 3 and 3 ′ is separated from the above-described parallel state. These are arranged so as to be in a non-parallel state with respect to the rotation axis P of the cylindrical part 2 to be inspected.

  In this case, as a matter of course, the rotation axis O1 of the cylindrical drive rotation roller 3 and the rotation axis O2 of the cylindrical drive rotation roller 3 'are maintained parallel to each other when viewed from a certain direction.

  That is, as shown in FIG. 2, the distance (horizontal direction) between the rotation axes O1 and O2 of the two pairs of cylindrical drive rotation rollers 3 and 3 ′ fixed in the parallel state is uniform. In this state, at least one of the rotation axes O1 or O2 is set so as to be inclined by an appropriate angle θ in the vertical direction.

  That is, the rotation axis O1 or O2 of the cylindrical driving rotary roller and the rotation axis P of the cylindrical part 2 to be inspected are set in a non-parallel state.

  By adopting such a configuration, as shown by an arrow X in FIG. 2, in addition to the rotational force, the inspected cylindrical part 2 has the inspected cylinder in the direction of the rotation axis P of the inspected cylindrical part 2. Since a force for moving the shape part 2 is generated, the inspected cylindrical part 2 can move in the direction of the rotation axis O1 or O2 of the cylindrical drive rotation roller 3 or 3 ′.

  That is, in the present invention, the rotation axis O2 ′ of the cylindrical drive rotary roller 3 ′ and the rotation axis P of the cylindrical part 2 to be inspected are determined so that the cylindrical part 2 to be inspected has the cylindrical drive. Arranged so that an angle α sufficient to move in the rotation axis direction P of the cylindrical part 2 to be inspected is formed between the rotation axes (between O2 ′ and P) along the surface of the rotation roller 3. It is necessary to be done.

  In the present invention, the cylindrical part 2 to be inspected placed on the two cylindrical driving rotary rollers 3 and 3 ′ is rotated by the rotation of the cylindrical driving rotary rollers 3 and 3 ′. While rotating on the driving and rotating roller, the cylindrical part 2 to be inspected can be moved straight in the direction of the rotation axis P (X direction).

  In FIG. 2, the rotation axis P of the cylindrical part 2 to be inspected is shown to have an angle with the axis O <b> 1 of the cylindrical drive rotation roller 3, but actually, the cylindrical drive rotation roller 3 ′. Since the displacement angle of the rotation axis O2 'is not so large, the rotation axis P of the cylindrical part 2 to be inspected and the axis O1 of the cylindrical drive rotation roller 3 are often kept substantially parallel.

  At this time, whether the rotation direction of the cylindrical driving rotary roller 3 ′ is the normal direction or the reverse direction, and the inclination angle θ in the vertical direction of the rotation axis O2 ′ of the cylindrical driving rotary roller 3 ′, in other words, the cylinder Depending on the direction of the intersecting angle α formed between the rotation axis O2 ′ of the cylindrical drive rotation roller 3 ′ and the rotation axis P of the cylindrical part 2 to be inspected.

  As a result, in the apparatus for inspecting surface characteristics 1 of the cylindrical part according to the present invention, the cylindrical part 2 to be inspected is determined while being spirally fed on the cylindrical driving rotary rollers 3 and 3 ′. In addition, the detection sensor unit 9 of the surface characteristic inspection means 4 fixed to the measurement unit 1 is monetized, and as a result, it is possible to perform two-dimensional scanning on the entire outer peripheral surface in a predetermined region of the cylindrical part 2 to be inspected. It is what you want to do.

  Furthermore, in the present invention, the rotational speed of the cylindrical drive rotary roller 3 or 3 ′, the rotational axis P of the cylindrical part 2 to be inspected, and the rotational axis O1 ′ of the cylindrical drive rotary roller 3 or 3 ′. By positively adjusting the angle (inclination angle) α formed between O2 ′ and O2 ′ or the angle θ obtained by tilting the rotation axes O1 ′ and O2 ′ in the vertical direction, It is possible to prevent the occurrence of an unmeasured portion (tiger cutting state) due to the effective measurement range and the change in the outer diameter of the cylindrical part 2 to be inspected.

  The cylindrical driving rotary roller in the present invention is a cylindrical body having an appropriate outer diameter, and the outer peripheral surface thereof has a relatively large friction coefficient in relation to the cylindrical part 2 to be inspected. Desirably, it is made of a material. For example, an appropriate synthetic resin material, rubber material, metal material, or the like is used.

  That is, the material of the cylindrical drive rotating roller 3 is selected according to appropriate surface friction resistance conditions with the cylindrical part 2 to be inspected. For example, the cylindrical part 2 to be inspected is a metal body and has a surface. In the case of a smooth polished finish, engineering plastics such as polyacetal (POM), MC nylon, etc. are suitable from the viewpoint of friction and sliding friction conditions.

  In addition, the length of the cylindrical drive rotating roller 3 is not particularly limited, but has a dimension that is at least longer than the length of the cylindrical part 2 to be inspected. It is desirable.

  Further, in the present invention, while the cylindrical part 2 to be inspected is placed on the cylindrical drive rotating roller 3 and simultaneously moves in the direction of the rotation axis of the cylindrical part 2 to be inspected. In order to inspect the surface characteristics of the cylindrical part 2 to be inspected, it is important that the cylindrical part 2 to be inspected is stably brought into contact with the surface of the cylindrical driving rotary roller 3. For this purpose, as shown in FIG. 2, the guide guide means or the pressing means 8 for pressing the cylindrical part 2 to be inspected against the cylindrical driving rotary roller 3 with an appropriate pressure is used as the cylindrical shape to be inspected. It is also desirable to arrange one or a plurality of parts along the movement path of the parts.

  In the present invention, as a method of inclining the rotation axes O1 ′ and O2 ′ of at least one of the cylindrical drive rotation rollers 3 with respect to the rotation axis P of the cylindrical part 2 to be inspected by a predetermined angle α. As shown in FIG. 7, at least one of appropriate bearing portions 10 and 10 ′ supporting the rotating shaft at both ends of the cylindrical drive rotating roller 3 or 3 ′ is moved by a predetermined distance in the vertical direction, for example. Alternatively, it can be realized by displacing.

  In such a specific example, the bearing is rotated whenever the angle of the rotation axis O1 ′, O2 ′ of the cylindrical drive rotating roller 3 or 3 ′ with respect to the rotation axis P of the cylindrical part 2 to be inspected needs to be corrected. There is a problem that the position of the camera must be changed, and the operation or work for the change is complicated and takes time.

  Therefore, in another specific example of the present invention, the one bearing portion 10 is always fixed, and the position of the other bearing portion 10 ′ can be continuously finely adjusted. Connected with the position adjusting device 7, taking into consideration the characteristics of the cylindrical part 3 to be inspected, the shaft position adjusting device 7 is operated as necessary, and the required inter-axis angle can be easily and quickly It may be configured to be set.

  In such a specific example, the fixed-side bearing unit 10 can absorb the load even when the rotary shaft is displaced by using an automatic centering bearing or the like, and can adjust the shaft center at the same time. Therefore, generation of vibration can be prevented.

  In the above-described specific example of the present invention, two pairs of rotating rollers 3 and 3 ′ arranged in parallel with each other are used as the cylindrical driving rotating roller 3. In the specific example, the number of the cylindrical drive rotating rollers 3 may be one.

  That is, in another specific example of the present invention, as shown in FIG. 3, a cylindrical driving rotation which is rotated at a predetermined rotational speed in a predetermined direction by a rotary driving body comprising an appropriate motor 19 or the like. One roller 3 is used.

  The configuration of the cylindrical drive rotation roller 3 can be set substantially in the same manner as the configuration of the cylindrical drive rotation roller 3 ′ in the specific examples described with reference to FIGS. 1 and 2.

  As the cylindrical part moving mechanism 5 to be inspected in this specific example, the difference in configuration between the cylindrical driving rotary roller 3 and the cylindrical driving rotary roller 3 ′ in the specific example described above is the same as this specific example. The bearing portion 10 ′ of the cylindrical drive rotating roller 3 in the example is configured such that the position thereof is displaced in the horizontal direction by the shaft position adjusting device 7.

  That is, in this specific example, as shown in FIG. 3C, the rotation axis O of the cylindrical driving rotary roller 3 is tilted in the horizontal direction (that is, changed from the dotted line position to the solid line position). ) It is set so that a predetermined angle α is formed with respect to the rotation axis P of the cylindrical part 2 to be inspected.

  Thus, the cylindrical part 2 to be inspected can be moved in the direction of the rotation axis of the cylindrical part 2 to be inspected while being rotated according to the same principle as in the above-described specific example.

  In this specific example, for example, an appropriate guide is provided in parallel with the rotational axis direction of the cylindrical part 2 to be inspected so that the cylindrical part 2 to be inspected does not separate from the cylindrical driving rotary roller 3. It is desirable to arrange the guide portions 11 and 11 ′.

  That is, in this specific example, along the movement path 12 of the cylindrical part 2 to be inspected on the cylindrical driving rotary roller 3, the guide guide portions 11 and 11 ′ of the cylindrical part 2 to be inspected are provided. It is desirable that it is provided.

  More preferably, in this specific example, in order to keep the cylindrical part 2 to be inspected stably in contact with the cylindrical driving rotary roller 3, as shown in FIG. 1 and FIG. It is to use together the pressing means 8 which consists of a structure.

It is desirable that the guide guide portion 11 or the pressing means 8 is disposed in the vicinity of the surface characteristic inspection means 4.
Next, still another specific example of the cylindrical part surface characteristic inspection apparatus 1 according to the present invention will be described.

  That is, in the two specific examples described above, the rotation axis O of the cylindrical drive rotation roller 3 is set at a predetermined angle, for example, 0.5 degrees, with respect to the rotation axis P of the cylindrical part 2 to be inspected. The cylindrical part 2 to be inspected is configured to be given a moving motion in the direction of the axis of rotation simultaneously with the rotational movement of the cylindrical part 2 to be inspected. Although it is possible to execute the inspection without any problem as long as the length of the component is relatively short, the cylindrical shape to be inspected as the length of the cylindrical portion 2 to be inspected increases in the longitudinal direction. A gap is formed between the component 2 and the cylindrical drive rotary roller 3, that is, the cylindrical component 2 to be inspected is in a contact state with the cylindrical drive rotary roller 3 per piece. As a result, the inspected The cylindrical part 2 and the cylindrical driving rotary roller 3 cannot be fully contacted with each other in the full length direction and the full width of the cylindrical driving rotary roller 3, and as a result, both ends of the cylindrical part 2 to be inspected. Since a non-contact portion of the cylindrical drive rotating roller 3 is generated and the cylindrical part 2 to be inspected is rotated, chatter vibration (with fluttering) is generated, so that an accurate surface characteristic inspection of the cylindrical part is performed. Things are impossible.

  As a result of intensive studies by the inventors of the present application, this phenomenon is not particularly problematic as long as the length of the cylindrical part 2 to be inspected is short, but it is known that the phenomenon occurs when the length is long to some extent. Therefore, the limit is that the cylindrical part 2 to be inspected has a long portion 2 to 5 times the outer diameter dimension of the cylindrical part 2 to be inspected, that is, the length of the diameter. It has been found that the chatter vibration is small and the inspection by the surface characteristic inspection means 4 can be executed sufficiently and accurately.

  Therefore, on the contrary, in the thin or long cylindrical part 2 to be inspected having a long part of 5 times or more the outer diameter length, the cylindrical part shown in FIG. 1 or FIG. It was understood that in the surface property inspection apparatus 1 in this case, it may be difficult to inspect the surface property of an accurate cylindrical part.

  Therefore, in this specific example, as in the specific example described above, the rotating shaft O itself of the cylindrical driving rotary roller 3 is used as the cylindrical drive component moving mechanism 5 to be tested. Instead of adopting a configuration in which the rotation axis P is tilted, the rotation axis O of the cylindrical drive rotation roller 3 is fixed, and the cylindrical part 2 to be inspected is separately connected to the cylindrical part 2 to be inspected. A configuration in which a cylindrical part moving mechanism 5 to be inspected that can apply a moving force in the direction of the rotation axis P is separately provided.

  That is, in this specific example, the cylindrical part 2 to be inspected is mounted on its surface and rotated in a predetermined direction, and is rotated on the driving rotary roller 3. A cylindrical part surface characteristic inspection apparatus 1 comprising surface characteristic inspection means 4 for inspecting the surface characteristic of the cylindrical part 2 to be inspected arranged close to the surface of the cylindrical part 2 to be inspected. A cylindrical shape for inspecting the surface characteristics of the cylindrical part to be inspected by moving the cylindrical part 2 to be inspected in a predetermined direction and moving it in the rotation axis direction P of the cylindrical part 2 to be inspected. In the component surface property inspection apparatus 1, the cylindrical part moving mechanism 5 to be inspected is configured separately from the cylindrical drive rotating roller 3. It has a function of moving the inspected cylindrical part 2 in the direction of the rotation axis P of the inspected cylindrical part 2 in contact with a surface part other than the surface part connected to the cylindrical drive rotating roller 3. This is a surface characteristic inspection apparatus 1 for a cylindrical part.

  If this specific example is described in further detail, the cylindrical part moving mechanism 5 to be inspected used in the cylindrical part surface characteristic inspection apparatus 1 in this specific example is provided with the surface characteristic inspection means 4. It is desirable that at least one is arranged in the vicinity of.

  Further, the cylindrical part moving mechanism 5 to be inspected in this specific example is, for example, a driven disk-like or cylindrical shape rotatably supported on an appropriate support portion 14 as shown in FIG. The direction of the axis of the rotation axis of the free rotation roller 13 is set to a predetermined angle with the rotation axis direction P of the cylindrical part 2 to be inspected.

  Further, the cylindrical part moving mechanism 5 to be inspected configured by the free rotating roller 13 and the support portion 14 in this specific example is rotated by an appropriate feed angle adjusting means 15. An angle α formed between the direction of the axis of the shaft and the rotational axis direction P of the cylindrical part 2 to be inspected can be set to an arbitrary angle freely and easily. It is also desirable.

  That is, in this specific example, the angle formed by the rotation axis of the free rotating roller 13 and the rotation axis P of the cylindrical part 2 to be inspected can be arbitrarily changed via the predetermined adjusting mechanism 15. It is configured.

  Further, in this specific example, a plurality of the free rotating rollers 13 and 13 ′ are arranged on both sides of the surface characteristic inspection means 4 along the rotational axis direction P of the cylindrical part 2 to be inspected. It is also desirable that

  In this specific example, as described above, the length of the cylindrical part 2 to be inspected is 5 times or more the outer diameter (diameter) of the cylindrical part 2 to be inspected, preferably 50 times or less. In the above-described specific example, the cylindrical part 2 to be inspected (including what is commonly referred to as a shaft part) in the range of 2 has two cylindrical shapes because the vibration increases as described above. The driving rotary roller is installed in parallel and without tilting in the axial direction so that the cylindrical part 2 to be inspected has the same axial direction on the two cylindrical driving rotary rollers 3 and 3 ′. Placed on.

  Further, as shown in FIGS. 5 and 6, for example, a free pinch roller (driven rotation roller) having the same rotational axis direction as that of the cylindrical drive rotation roller 3 so as to hold the cylindrical part 2 to be inspected. 13 is installed.

  In this state, when the cylindrical driving rotary roller 3 is rotated, the cylindrical part 2 to be inspected is reversely rotated, and the pinch roller 13 in contact therewith is further reversely rotated, so that the cylindrical driving rotary roller 3 is rotated. The cylindrical part 2 to be inspected is in a space sandwiched between two cylindrical drive rotary rollers 3 and 3 'and one or a plurality of pinch rollers (driven rotary rollers) 13. Rotates stably.

  More specifically, to explain the specific example, a plurality of the pinch rollers 13 are provided, and the central axis direction of the rotation axis of at least one of the pinch rollers (driven rotation roller) 13 ′ is the cylindrical drive rotation. Setting the feed angle by setting the roller 3 and the rotation axis of the cylindrical part 2 to be inspected parallel to each other and tilting the roller 3 and the rotation axis P of the cylindrical part 2 to be inspected to form a predetermined angle. When the pinch roller (driven rotation roller) 13 ′ with the feed angle comes into contact with the cylindrical part 2 to be inspected being rotated on the spot, it goes straight to the cylindrical part 2 to be inspected. When the movement is excited, the cylindrical part 2 to be inspected can be spirally fed in a straight line while rotating on the axes of the two cylindrical driving rotary rollers 3 and 3 ′.

  The straight traveling speed of the cylindrical part 2 to be inspected by the pinch roller (driven rotation roller) 13 ′ can be changed by changing the angle of the feed angle α of the pinch roller 13 ′.

  In this specific example, it is desirable that at least a portion of the free rotating roller including the pinch roller 13 that is in contact with the surface of the cylindrical part 2 to be inspected is provided with a member having a large friction coefficient. For example, the material of the free rotation roller 13 is suitably an elastic body such as urethane rubber having a higher surface friction resistance than the cylindrical drive rotation roller 3.

In selecting a material for each roller, it is desirable not to use a material that may damage the cylindrical part 2 to be inspected.
On the other hand, in the above-described specific example, instead of using the two cylindrical driving rotary rollers 3 and 3 ′, one cylindrical driving rotary roller 3 is used, and at the same time, the cylindrical shape to be inspected is used. For example, it has a configuration in which at least one free rotation roller 13 formed of a pinch roller (driven rotation roller) having a feed angle with respect to the component 2 is disposed so as to contact the cylindrical component 2 to be inspected. May be.
