In the field of assembly of mechanical devices, it is often necessary to select the appropriate spacer between the housings in order to achieve an accurate assembly between the housings.
For example, in a power plant of a hybrid vehicle, an engine and a motor are generally included as power sources, and therefore a transmission has two power inputs (engine and motor) and at least one power output. In actual assembly, due to assembly errors of the assembly surfaces between the engine and the transmission case and between the motor and the transmission case, it is necessary to provide a spacer between the assembly surfaces when the assembly is performed to achieve a desired assembly accuracy.
Conventionally, in order to measure the clearance between the fitting surfaces, it is necessary to first fix one of the members such as the transmission case, the engine, or the motor by clamping, suspend the other member with the positioning surfaces in alignment with each other, measure the clearance between the fitting surfaces in this suspended state by hand, and prepare the gasket for the subsequent actual fitting based on the measured dimensional parameters.
However, the technical defects of the conventional measurement method are mainly as follows: firstly, the working efficiency is low because the hoisting equipment is needed for carrying out the suspension operation; secondly, since the measurement is performed in a suspended state and is performed manually, the measurement accuracy is limited.

Detailed Description
The technical solutions of the present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. Hereinafter, the structure of the position degree measuring apparatus provided in the present application and the assembling relationship thereof will be first described, then the measuring principle will be explained in conjunction with the position degree measuring method, and finally the sensor assembly that can be used by the apparatus of the present application will be explained.
As shown in fig. 1, a position degree measuring apparatus according to a preferred embodiment of the present application includes: a base 10, the base 10 being fixedly or movably mounted to the frame; a carriage 11, the carriage 11 being slidably mounted to the base 10 in a longitudinal direction Y, the carriage 11 being provided with a mounting base 12 in a position-adjustable manner; at least one positioning measuring rod 13, wherein the positioning measuring rod 13 is installed on the installation seat 12 and extends forwards along the longitudinal direction Y, is used for positioning and matching with a positioning hole 101 in a positioning surface 100 of the component to be measured and is perpendicular to the positioning surface 100; at least three positioning contacts 14, wherein the at least three positioning contacts 14 are mounted on the mounting base 12 and extend forwards along the longitudinal direction Y, and are used for being vertically positioned and matched with the positioning surface 100 of the component to be tested; and at least three measuring heads 15, wherein the measuring heads 15 are arranged on the mounting seat 12 and are used for being vertically matched with the assembling surfaces 201 and 202 of the component to be measured in a positioning way.
The base 10 can be fixedly mounted to the machine frame or can be movably mounted to the machine frame and serves as a base part of the position measuring device. In the case where the base 10 is movably mounted to the rack, approaching or moving away from the object to be measured can be achieved by moving the base 10.
The carriage 11 is intended to carry most of the measuring components of the measuring device (a measuring rod or a measuring head, etc., as described below), and is slidably mounted to the base 10 in the longitudinal direction Y. Depending on the application, the sliding frame 11 may be installed above the base 10, or as shown in fig. 1, the sliding frame 11 may be installed on the bottom surface of the base 10 in a longitudinally slidable manner, i.e. below. The carriage 11 may be slidably mounted to the base 10 by means of guide rails. Due to the slidable design of the carriage 11 in the longitudinal direction Y, it can be facilitated to achieve that the measuring part approaches or moves away from the object to be measured.
At least one positioning measuring rod 13 is mounted on the mounting base 12, and the positioning measuring rod 13 is mounted on the mounting base 12 and extends forwards along the longitudinal direction Y, and is used for being positioned and matched with a positioning hole 101 in a positioning surface 100 of the component to be measured and perpendicular to the positioning surface 100, as shown in fig. 4 and 5. Due to the above-mentioned position adjustment or position floating design of the mounting base 12 relative to the sliding frame 11, it is possible to compensate for the positional deviation of the positioning measuring bar 13 relative to the positioning hole 101 in the positioning surface 100 of the component to be measured, thereby ensuring that the positioning measuring bar 13 is in positioning engagement with the positioning hole 101 of the positioning surface 100 of the component to be measured in a state of being kept perpendicular to the positioning surface 100, for example, inserted into the positioning hole 101.
The number of the positioning measuring rods 13 may be one or more. For example, in the preferred embodiment of the present application, there are two positioning bars 13, and the two positioning bars 13 are arranged at a distance from each other in the transverse direction X.
Since the positioning surface 100 of the component to be measured has relatively high positioning accuracy, after the positioning measuring rod 13 is positioned and matched with the positioning hole 101 on the positioning surface 100 on the premise of being perpendicular to the positioning surface 100, the position of the positioning measuring rod 13 relative to the positioning surface 100 can be accurately determined. Specifically, in a case where the positioning surface 100 is abstracted to a plane, the center axis direction or the axial direction of the positioning pin 13 can be abstracted to a perpendicular line perpendicular to the positioning surface 100 by the positioning engagement of the positioning pin with the positioning hole 101. In the case of a plurality of positioning rods 13, each positioning rod 13 can be abstracted as a perpendicular line perpendicular to its corresponding positioning surface.
For accurate sensing of the positioning surface 100, at least three positioning contacts 14 are provided on the mounting base 12, which at least three positioning contacts 14 each extend forward in the longitudinal direction Y for perpendicular positioning engagement with the positioning surface 100 of the component to be measured. In this embodiment, the three-dimensional spatial position parameters of the positioning surface 100 can be determined more accurately by using at least three contact points of the positioning contact 14 and the positioning surface 100. In general, the positioning surface can be determined by using three positioning contacts 14 (three points determine a plane), and in the preferred case of the present application, it is more advantageous to determine the positioning surface by using the contact points sensed by four or more contacts, and any three points of the positioning surfaces can be used to determine the positioning surface. Preferably, the positioning contacts 14 are distributed adjacent to the positioning spindle 13, so that the relative error between the positioning surface sensed by the positioning contacts 14 and the perpendicular to the positioning surface sensed by the positioning spindle 13 can be controlled to be smaller. It will be appreciated that the positional relationship of the positioning contact 14 to the positioning stylus 13 is not limited to the specific form shown in the figures.
As can be seen from the above description, the positioning contacts 14 can define a virtual vertical positioning plane by sensing the positioning plane 100, and the axial direction or the central axis of the positioning measuring rod 13 can define a perpendicular line perpendicular to the positioning plane, so that the intersection point between the perpendicular line and the virtual vertical positioning plane can be known. The number of the intersection points depends on the number of the positioning measuring rods 13, and in the case of designing one positioning measuring rod 13, one intersection point can be determined; in the case shown in the figure, two intersection points can then be determined, one of which serves as a basis for measuring the position degree and the other of which serves as a basis for a correction.
In order to arrange the positioning contacts 14, as shown in fig. 1 and 2, the position measuring device includes a first mounting frame 16 fixedly disposed on the mounting base 12, wherein the first mounting frame 16 is located between the two positioning measuring bars 13 and provides a mounting base for the positioning contacts 14 located below the positioning measuring bars 13. Preferably, the position degree measuring device includes a second mounting bracket 17 fixedly disposed on the mounting base 12, and the second mounting bracket 17 is located above the positioning measuring rod 13 and provides a mounting base for the positioning contact 14 located above the positioning measuring rod 13. As mentioned above, the positioning contact 14 is preferably arranged adjacent to the positioning measuring bar, so in the preferred embodiment shown in fig. 2, several positioning contacts 14 can be arranged above and below the positioning measuring bar, and further serve as a mounting base for the positioning contacts 14 through the above-mentioned first mounting frame 16 and second mounting frame 17, respectively.
The positioning surface 100 is mainly used as a positioning base for the component or object to be measured. The detection measurement of the position degree requires the detection of the spatial position relationship, in particular the distance, between the mounting surface and the positioning surface on the basis of the positioning surface. In order to determine the mounting surface, the device for measuring the position of the present application is provided with at least three measuring heads 15, as shown in fig. 1 and 2, which measuring heads 15 are mounted on the mounting base 12 for vertical positioning engagement with the mounting surfaces 201, 202 of the component to be measured. The three contact points of the three measuring heads 15 with the mounting surface can sense the exact position of the mounting surface 201 or 202 in the three-dimensional space. Preferably, more measuring heads can be designed, and the arrangement of the positioning contacts and the technical effects thereof can be referred to.
The mounting base for the measuring head 15 can be chosen in many ways, for example on the carriage 11, but preferably, as shown in fig. 1 and 2, the second mounting frame 17 provides the mounting base for the measuring head 15. In this preferred embodiment, since the measuring head and (at least a part of) the positioning contacts have the same arrangement basis, the spatial measurement of the positioning surface and the spatial measurement of the mounting surface have a common basis, so that errors that may occur when evaluating the spatial positional relationship between the two can be further reduced. In order to facilitate the measuring head 15 to maintain a perpendicular relationship to the mounting face, the orientation of the measuring head 15 is preferably arranged in a horizontal plane but inclined to the longitudinal direction Y, as shown in fig. 3. The angle of inclination a of the measuring head 15 in the horizontal plane relative to the longitudinal direction is adjustable.
According to different working conditions, the number of the assembling surfaces on the object to be measured or the component to be measured can be one, or two or more. Thus, a set of measuring heads 15 can be arranged for a mounting surface, the set of measuring heads 15 having at least three measuring heads (three points defining a plane).
Preferably, as shown in fig. 1, 2 and 3, the measuring head 15 comprises: a first group of measuring heads comprising at least three measuring heads 15 for vertical positioning cooperation with a first mounting face 201 of the component to be measured; a second group of measuring heads comprising at least three measuring heads 15 is provided for vertical positioning cooperation with the second mounting face 202 of the component to be measured. In this preferred embodiment, there are two mounting surfaces in the component or object to be measured: the first mounting surface 201 and the second mounting surface 202 are thus each assigned a respective set of measuring heads, so that the spatial position parameters of the respective mounting surfaces are determined by the respective measuring heads. Here, the measurement of the mounting surface by the measuring head can also refer to the measurement of the positioning surface by the positioning contact and the technical effects thereof.
In the case of two mounting faces, as shown in fig. 3, the inclination angle α 1 of the first group of measuring heads in the horizontal plane with respect to the longitudinal direction is different from the inclination angle α 2 of the second group of measuring heads in the horizontal plane with respect to the longitudinal direction; the measuring head can also be designed identically, in that it is ensured that the direction of extension of the measuring head is perpendicular to the mounting surface, in order to achieve an exact measurement of the mounting surface. The above-mentioned inclination angle can be achieved by a hinge-fitting relationship.
As described above, the intersection point between the center axis of the positioning spindle and the positioning surface can be determined using the positioning spindle and the positioning contact, and the mounting surface can be determined by the measuring head for the mounting surface. Therefore, the distance between the intersection point and the fitting surface can be measured and obtained very accurately and easily. Based on the thought, the application also provides a position degree measuring method, which comprises the following steps: defining a positioning hole 101 in a positioning surface 100 of the component to be measured by using the positioning measuring rod, and further determining the axial direction or the central axis of the positioning measuring rod; the positioning contact is utilized to define a positioning surface 100 of the component to be measured, and then an intersection point of a central axis of the positioning hole and the positioning surface is defined, namely the intersection point of the central axis of the positioning measuring rod and the positioning surface is equivalent to the intersection point of a perpendicular line of the positioning surface on the positioning surface in mathematical and geometric sense; the measuring head is then used to define the mounting surface of the component to be measured, so that the distance between the intersection point and the mounting surface can be precisely and easily obtained.
This is further explained below with the examples shown in fig. 4 and 5. It should be noted that the examples shown in fig. 4 and fig. 5 are only for illustrative purposes and do not limit the technical solutions claimed in the present application. Under the same or similar mechanism or principle, the technical scheme of the application can also be used in other applicable working condition occasions.
For example, fig. 4 and 5 are schematic views exemplarily showing a measuring object using the position degree measuring apparatus according to the preferred embodiment of the present application, in which a is a motor housing and B is a transmission housing.
As described in the background of the invention section, in the conventional assembly method, when the motor housing and the transmission housing are assembled together, the gap between the assembling surfaces needs to be measured. Firstly, the gearbox shell B is fixed by using a clamp, then the motor shell A is hoisted, and the positioning surfaces of the gearbox shell B and the motor shell A are positioned and attached to each other, so that the gearbox shell B and the motor shell A are ensured to be in accurate relative position relation. Then, the gap between the two corresponding assembling surfaces is manually measured in the suspension state, and then the gasket is prepared according to the measured dimension parameters for subsequent actual assembling.
In the technical solution of the present application, first, the gearbox housing B is measured by using a position degree measuring device: the positioning measuring rod is matched in a positioning hole of a positioning surface of the gearbox shell B in a positioning mode, and the positioning contact is used for measuring the positioning surface of the gearbox shell B, so that an intersection point of the positioning measuring rod on the positioning surface is determined; in addition, the measuring head is used for measuring the assembling surface of the gearbox shell B, so that the position relation, particularly the distance between the intersection point and the assembling surface can be accurately and conveniently obtained.
Subsequently, the motor case a is similarly measured by the position degree measuring device: positioning and matching the positioning measuring rod in a positioning hole of a positioning surface of the motor shell A, and measuring the positioning surface of the motor shell A by using the positioning contact head so as to determine an intersection point of the positioning measuring rod on the positioning surface; in addition, the measuring head is used for measuring the assembling surface of the motor shell A corresponding to the assembling surface on the gearbox shell B, so that the position relation, particularly the distance, between the intersection and the assembling surface of the motor shell A corresponding to the assembling surface on the gearbox shell B can be accurately and conveniently obtained.
Since the motor housing a and the transmission housing B have the same positioning surfaces (not physically identical but have a common positioning base by positioning engagement of the positioning surfaces during assembly), by obtaining the distance between the intersection and the mounting surface of the motor housing a and the distance between the intersection and the corresponding mounting surface of the transmission housing B, it is possible to measure and obtain the positional information between the two corresponding mounting surfaces, particularly the relative positional relationship between the two corresponding mounting surfaces, particularly the distance between the two corresponding mounting surfaces, when the positioning surfaces of the motor housing a and the transmission housing B are positioned and engaged with each other. According to the measured position parameter information, the thickness of the gasket required between two corresponding assembling surfaces can be directly determined.
This has several advantages over the traditional way of manually measuring where a casing has to be suspended. Firstly, hoisting operation is not needed, so that the safety and the working efficiency of detection and measurement operation are improved to a great extent; secondly, the method does not need manual measurement but is based on automatic measurement of a positioning surface, so that the accuracy of a measurement result is improved.
The above is an explanation of the case of two corresponding mounting surfaces, but it will be understood by those skilled in the art that the present application can be applied to the case where there are multiple pairs of mounting surfaces, for example, in the case shown in fig. 4 and 5, two pairs of corresponding mounting surfaces are designed between the motor housing a and the transmission housing B.
In addition, it should be noted that, with the technical solution of the present application, in addition to measuring the distance in the position degree parameter between the intersection point and the mounting surface, the spatial position relationship between the intersection point and the mounting surface can also be measured. Specifically, because at least three positioning contacts and three measuring heads are designed for the positioning surface and the assembling surface, the technical scheme of the application can be used for measuring the respective and relative spatial position relationship of the virtual positioning surface and the assembling surface, particularly the measured relative angle relationship between the corresponding assembling surfaces. For example, when the assembly surface of the motor housing a is measured by the position degree measuring device and then the corresponding assembly surface of the transmission housing B is measured, in addition to the distance parameter, the relative angle relationship between the two corresponding assembly surfaces can be measured, although theoretically, the two assembly surfaces should be parallel to each other, because the manufacturing error relationship may cause a small angle between the two assembly surfaces, after the distance and angle information is obtained, a gasket with a non-uniform thickness can be designed (that is, a distance and an angle consistent with the measurement result are formed between two side surfaces of the gasket respectively attached to the two assembly surfaces), so that more accurate gasket selection is realized. For example, a base horizontal plane may be selected, and then an intersection of the measured mounting surface of the motor housing a and the base horizontal plane may be obtained by fitting, and then an intersection of the measured corresponding mounting surface of the transmission housing B and the base horizontal plane may be obtained by fitting, and the angle between these intersections may be obtained.
The positional degree measuring apparatus and the measuring method provided by the present application are described above. As described above, in order to measure the positioning surface or the mounting surface, it is necessary to use a sensor device such as the positioning contact or the measuring head. Conventionally, a pen-type sensor may be used as the contact head or the measuring head. In the preferred embodiment of the present application, however, two sensor solutions are proposed. Both sensor solutions can be used for the positioning contact or measuring head as described above, depending on the operating requirements. The two sensor schemes are described in detail below.
As shown in fig. 6, there is provided according to the present application a displacement sensor including: a base member 110, the base member 110 including a base portion 111 extending in a longitudinal direction X1 and an extension 1111 extending in a height direction Z1 from a first end 112 of the base portion 111; an elastic deformation body 120 connected to the extension portion 1111 through a connection end 1201 and extending in the longitudinal direction X1 in a spaced-adjacent manner to the base member 110, the elastic deformation body 120 having a contact 130 attached thereto, the contact 130 being oriented so as not to be in the longitudinal direction X1, the elastic deformation body 120 being capable of swinging by elastic deformation with respect to the base member 110 around the connection end 1201 when the contact 130 abuts against a measurement point of the component to be measured; and a displacement sensing mechanism provided between the base member 110 and the elastically deformable body 120, the displacement sensing mechanism for sensing a displacement variation amount of the elastically deformable body 120 with respect to the base member 110.
According to the technical solution of the present application, the orientation of the contact 130 mounted on the elastic deformation body 120 is designed not to be in the longitudinal direction X1, and when the contact 130 is in contact with the measurement point of the component to be measured, the displacement sensing mechanism can obtain the measurement value by sensing the displacement variation of the elastic deformation body 120 relative to the base member 110. Therefore, in the present invention, the length of the displacement sensor itself in the longitudinal direction X1 is not limited by the size of the measurement space, and therefore, the requirement for space in the direction of the contact 130 is reduced, so that the displacement sensor of the present invention can perform measurement in a narrow space work place.
As shown in fig. 10, for example, the length of the contact 130 from the connection end 1201 in the extending direction of the elastic deformation body 120 is L, the length of the displacement sensing mechanism from the connection end 1201 in the extending direction is S, when the contact 130 is in contact with the measurement point of the component to be measured, the maximum moving distance of the contact 130 along the height direction Z1 is D, and at this time, the maximum swing angle α of the elastic deformation body 120 is. According to the sine theorem, the ratio of the displacement parameter directly acquired by the displacement sensing mechanism to the moving distance D is equal to the ratio of the length S to the length L. It can be understood that, when the displacement parameter directly acquired by the displacement sensing mechanism is unchanged from the maximum angle α of the elastic deformation body 120, the greater the length L of the contact 130 from the connection end 1201 in the extending direction of the elastic deformation body 120, the greater the range of measurement that can be measured by the sensor through the displacement sensing mechanism. Therefore, the range of the displacement sensor can be effectively increased by increasing the extension length of the elastic deformation body 120, so that the flexible applicability of the displacement sensor in various working conditions is further improved.
As shown in FIG. 6, the base member 110 includes a base portion 111 extending in a longitudinal direction X1 and an extension portion 1111 extending in a height direction Z1 from a first end 112 of the base portion 111 and installed through a mounting hole or a card slot, for exampleA mounting structure capable of fixedly or movably mounting the base member 110 to the frame may be provided to the base portion 111 or the extension portion 1111. The elastic deformation body 120 is connected to the extension portion 1111 through the connection end 1201 and extends along the longitudinal direction X1 in a spaced-adjacent manner with respect to the base member 110, and the elastic deformation body 120 or the connection end 1201 is made of an elastic material (such as plastic or elastic metal), so that the contact 130 mounted on the elastic deformation body 120 can elastically float in the height direction Z1, wherein the elastic modulus of the elastic deformation body 120 can be 170 × 103Mpa to 190X 103Mpa, preferably 180X 103Mpa. The contact head 130 is used for abutting against a measuring point of the component to be measured during measurement, and the contact head 130 can be set to different extending directions according to actual working condition environments. When the contact head 130 collides with the measuring point, the pressure applied to the contact head 130 by the measuring point enables the elastic deformation body 120 to swing around the connecting end 1201 and through elastic deformation relative to the base member 110, so that the displacement sensing mechanism arranged between the base member 110 and the elastic deformation body 120 senses the displacement variation of the elastic deformation body 120 relative to the base member 110, and further the displacement variation of the measuring point is obtained, thereby achieving the purpose of measurement.
As shown in fig. 6, the base member 110 is a rod-shaped member extending along the longitudinal direction X1, and the rod-shaped member may be made of hard plastic or metal. The elastic deformation body 120 is a rod-shaped member extending in the longitudinal direction X1, and preferably, the elastic deformation body 120 is arranged in parallel with the base portion 111 of the base member 110 when the displacement sensor is in the non-operating state, so that the structural space of the displacement sensor in the height direction Z1 can be fully utilized.
In order to further improve the flexibility of the elastic deformation body 120 to swing with respect to the base member 110, as shown in fig. 6 and 7, the thickness of the middle portion of the connecting end 1201 of the elastic deformation body 120 is thinner than the thickness of the elastic deformation body 120 in one embodiment, and the minimum thickness of the connecting end 1201 in the height direction Z1 is preferably 0.3 mm. In another embodiment, the inner side of the link end 1201 facing the base member 110 or the inner side of the extension 1111 adjacent to the link end 1201 may be provided with a notch 121 extending therethrough in the transverse direction Y1.
