It should be understood that the preferred embodiments are presented by way of illustration only and not by way of limitation.

It should be noted that the illustrations provided in the following embodiments merely illustrate the basic concept of the present application by way of illustration, and only the components related to the present application are shown in the drawings and are not drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of the components in actual implementation may be arbitrarily changed, and the layout of the components may be more complicated.

In the related art, some detection devices indirectly judge whether the position degree of the hole/pin is qualified or not according to whether the detection pin of the detection tool passes through the envelope range of the hole/pin tolerance zone, but the method can only qualitatively but not quantitatively judge whether the part is qualified or not, but can not measure the specific difference value of the part deviating from the design state, and can not intuitively guide the subsequent improvement work; or whether the hole/pin position degree is qualified or not is judged by scoring the preset hole/pin position on the part, but the method can damage the part; or whether the holes/pins of the parts are qualified or not is judged by calculating the position degree through computer modeling, but the method has high input cost and low efficiency and is not suitable for mass detection.

In view of this, an embodiment of the present application provides a position detecting device, which converts the position of a part to be detected (hole/pin to be detected) into a scale value that can be directly read by detecting the center automatic alignment function of the pin, so as to calculate the position deviation of the hole/pin, determine whether the part is qualified according to a preset position deviation range, and if not, adjust and modify according to a specific position value. The device detects the movement of the hole/pin to be detected through the detection mechanism 11, and no damage is caused to parts. The device assembled by the mechanical parts has lower production cost than computer modeling cost and high detection speed, thereby being capable of mass production and mass detection. Referring to fig. 1, fig. 1 is a general structural assembly diagram of a position detecting device according to an embodiment of the present application. The figure shows the components of the detection device, including: the device comprises a fixed base 1, a first sliding block 2, a first limit screw 3, a sliding seat 4, a second sliding block 5, a second limit screw 6, a first jackscrew 7, a first jackscrew 8, a limit block 9, a detection pin sleeve 10, a detection mechanism 11, a detection pin handle 12 and a spring 13. Fig. 2 is an exploded view showing a structure of a position detecting device, wherein arabic numerals in the drawings respectively represent: the device comprises a fixed base 1, a first sliding block 2, a first limit screw 3, a sliding seat 4, a second sliding block 5, a second limit screw 6, a first jackscrew 7, a second jackscrew 8, a limit block 9, a detection pin sleeve 10, a first detection pin 111, a second detection pin 112, a detection pin handle 12 and a spring 13.

The position degree detection device includes: a fixed base 1 for mounting to a target location; the sliding mechanism comprises a first sliding component and a second sliding component which are axially connected in an overlapping manner, and the first sliding component is connected with the fixed base 1; the detection mechanism 11 is axially arranged in the second sliding component in a penetrating way and is used for detecting the position degree of the pin/hole to be detected; the first sliding component and the second sliding component are respectively provided with a mark; wherein, the first sliding component drives the detection mechanism 11 to move along a first direction, so that the mark indicates a first displacement of the detection mechanism 11; the second sliding component drives the detection mechanism 11 to move along a second direction, so that the mark indicates a second displacement of the detection mechanism 11; wherein the first direction and the second direction are perpendicular to each other.

Specifically, as shown in fig. 1, a direction in which the first sliding member slides is defined as a first direction, and a direction in which the second sliding member slides is defined as a second direction. Wherein the first direction and the second direction are perpendicular to each other may be understood as the first direction and the second direction are oriented at 90 ° in a planar coordinate system, the first direction may be a direction along the X-axis/Y-axis movement, and the second direction may be a direction along the Y-axis/X-axis movement. For example, as shown in the installed position of fig. 1, the first sliding assembly moves toward the X-axis direction and the second sliding assembly moves toward the Y-axis direction. The positional degree is a range in which the axis or the center plane of one body allows the position of itself to change, that is, a range in which the actual position of the axis or the center plane of one body changes, and is an index for limiting the amount of change in the actual position of the element to be measured to an ideal position.

The axial overlap arrangement may be in the Z-axis direction, with the first and second slide assemblies being stacked, and the first slide assembly may be located below the second slide assembly such that when the first and second slide assemblies are independently moved about their own directions of movement. When the first sliding component moves towards the first direction, the second sliding component connected with the first sliding component and the detection mechanism 11 connected with the second sliding component are allowed to move for a certain distance along the first direction to obtain a first displacement amount, when the second sliding component moves towards the second direction, the detection mechanism 11 connected with the second sliding component is allowed to continue to move along the second direction to obtain a second displacement amount, and therefore the displacement amount moved in the two directions obtains a position degree deviation, and the position degree deviation can be understood as a vector of the first displacement amount and the second displacement amount.

The first displacement amount and the second displacement amount can be indicated by corresponding marks, and the marks can be corresponding scale marks. If the pin/hole to be detected of the part to be detected deviates from the theoretical position, the displacement generated in two specific directions can be visually reflected through the scale marks, so that the function of quantifying the degree of the pin/hole to be detected is realized.

The detection device converts the position degree of a part to be detected (a hole/pin to be detected) into a scale value which can be directly read by detecting the center automatic alignment function of the pin and enabling the detection mechanism 11 to displace in the first direction and/or the second direction, so that the position degree deviation of the hole/pin is calculated. Judging whether the part is qualified or not according to a preset position deviation range, if not, adjusting and modifying according to specific position values, and improving the detection efficiency of the part while not damaging the part.

In some embodiments, when the slide 4 moves along the first direction to a target distance, the target distance is the position of the pin/hole to be measured in the X direction under ideal condition, and the difference between the position where the slide starts to move and the position where the target distance is located is the first displacement; the sliding seat 4 is installed on the fixed base 1 through the first sliding block 2, and at the moment, the second sliding block 5 can be moved to drive the detection mechanism 11 to move along the direction of the second sliding groove, so that the detection mechanism 11 moves along the second direction to reach a target distance, the target distance is the Y-direction position of the pin/hole to be detected under an ideal state, and the position difference from the position where the detection mechanism starts to move to the target distance is the second displacement.

More preferably, the first scale is provided at a partial area of the first slider 2 protruding out of the first runner, so that the distance of movement can be directly observed through the boundary line of the first runner during movement. Similarly, the second slider 5 is provided identically, except that the end of the second slider 5 extending out of the second chute is connected to the detection mechanism 11.

In this embodiment, the locking member may comprise a jackscrew to fix the slide 4 and the slider in the slide groove formed in the slide 4. Wherein the plurality of locking elements may comprise a first jackscrew 7 and a second jackscrew 8. One or more first mounting holes can be arranged at intervals along the direction of the body of the first sliding groove, and a plurality of first jackscrews 7 pass through the first mounting holes to be abutted with the first sliding blocks 2 in the first sliding groove so as to keep the sliding seat 4 and the first sliding blocks 2 relatively fixed; one or more second mounting holes can be arranged at intervals along the direction of the body of the second sliding groove, and a plurality of second jackscrews 8 pass through the second mounting holes to be abutted with the second sliding blocks 5 in the second sliding groove, so that the sliding seat 4 and the second sliding blocks 5 are kept relatively fixed. In some embodiments, the number of first and second jackscrews 7, 8 may be the same or different. Illustratively, one first jackscrew 7 passes through the first mounting hole and two second jackscrews 8 pass through the second mounting hole; illustratively, as shown in fig. 1, one for each of the first and second jackscrews 7, 8 is provided.

Likewise, in some embodiments, the placement locations of the plurality of secondary jackscrews 8 may be the same or different.

Specifically, after aligning the first side of the slide 4 with the 0mm mark line of the first scale on the first slider 2, the first jackscrew 7 is installed in the first installation hole, so that the relative position of the slide 4 and the first slider 2 is kept fixed. And in order to measure specific numerical values, the first jackscrew 7 is only installed in the first mounting hole when the initial assembly precision is calibrated and the subsequent periodic precision is rechecked, and when the measurement is to be carried out, the first jackscrew 7 is required to be loosened, so that the sliding seat 4 can freely slide along the first sliding block 2 in the first direction.

Similarly, after aligning the second side of the slide 4 with the 0mm mark line of the first scale on the second slide 5, the first jackscrew 8 is installed in the second installation hole, so that the relative position of the slide 4 and the second slide 5 is kept fixed, and for measuring specific numbers, the first jackscrew 8 is installed in the second installation hole only when the initial assembly precision is calibrated and the subsequent periodic precision is rechecked, and when the measurement is to be performed, the first jackscrew 8 is required to be loosened, so that the second slide 5 can slide freely along the second slide groove in the second direction.

The first limiting piece is a first limiting screw 3, and the second limiting piece is a second limiting screw 6. Along the first direction, the overlapping portion between the projection surface of the first limiting member and the projection surface of the sliding seat 4 may be understood that the first limiting screw 3 is inserted through the first sliding block 2 and the top end of the first limiting screw protrudes out of the first sliding block 2, so that the top end of the first limiting screw 3 is higher than the top surface of the first sliding groove. Therefore, after the first sliding groove moves to the limit position along the first direction, the first limit screw 3 contacts with the side wall surface of the sliding seat 4 to prevent the sliding seat 4 from moving along the first direction, so that the sliding seat 4 is prevented from being separated from the first sliding block 2. Similarly, along the second direction, the overlapping portion between the projection surface of the second limiting member and the projection surface of the sliding seat 4 may be understood that the second limiting screw 6 is inserted into the second sliding block 5 and the bottom end of the second limiting screw protrudes out of the second sliding block 5, so that the bottom end of the second limiting screw 6 is located below the bottom surface of the second sliding groove, that is, after the second sliding block 5 moves to the limit position along the second direction, the second limiting screw 6 contacts with the side wall surface of the sliding seat 4 to prevent the second sliding block 5 from moving continuously along the second direction, thereby preventing the second sliding block 5 from being separated from the sliding seat 4.

The protruding direction of the first limit screw 3 is understood to be the direction opposite to the notch of the chute, so that the protruding portion of the first limit screw 3 contacts the side wall surface of the slide 4. Likewise, the second limit screw 6 is arranged in a similar manner.

Specifically, the first limit screw 3 is mounted on the sixth mounting hole of the first slider 2 along the direction perpendicular to the ground, the first limit screw 3 is not completely embedded into the first slider 2, and the cap peak of the first limit screw is higher than the plane of the first slider 2 with the first scale, so when the slide 4 slides on the first slider 2, the first limit screw 3 can prevent the slide 4 from separating from the first slider 2 after moving to the limit position. The second limit screw 6 is installed on the seventh installation hole of the second slide block 5 along the direction vertical to the ground, the second limit screw 6 is not completely embedded into the second slide block 5, and the screw cap peak is higher than the plane of the second slide block 5 with the second scale, so when the second slide block 5 slides on the slide seat 4, the second limit screw 6 can prevent the second slide block 5 from separating from the slide seat 4 after moving to the limit position.

In another embodiment, the detecting mechanism 11 includes any one of a first detecting pin 111 and a second detecting pin 112; the first detection pin 111 and the second detection pin 112 each comprise a guide section and a detection section, and the guide section penetrates through the second sliding assembly and is connected with the detection section; wherein the detection section of the first detection pin 111 is tapered to detect the position degree of the pin to be detected; the detection section of the second detection pin 112 is funnel-shaped to detect the position of the hole to be detected. The detection mechanism 11 further includes: the elastic piece is sleeved on the outer peripheral surface of the guide section, which extends out of the connecting part of the second sliding assembly and the detection section; and the detection pin sleeve 10 is sleeved on the outer peripheral surface of the guide section, which is positioned in the second sliding assembly.

In one embodiment, the first detection pin 111 includes three parts of a guide section, a flange, and a detection section. The diameter of the guiding section is consistent with the inner diameter of the first through hole, the diameter of the flange is larger than the outer diameter of the elastic piece, the elastic piece can be preferably a spring 13, the detecting section is conical, the large diameter of the detecting section is larger than the size of a part to be detected, and the small diameter of the detecting section is smaller than the size of the part to be detected. After the spring 13 is installed in the first detection pin 111, the detection pin sleeve 10 is integrally installed from bottom to top, and the tail end of the first detection pin 111 is fixed by the detection pin handle 12, so that the first detection pin 111 can freely slide along the detection pin sleeve 10 within a certain stroke in a specified direction and cannot be separated.

Specifically, the second portion of the second slider 5 is provided with a first through hole in which the detection pin bush 10 is inserted by interference fit. The interference fit is to enlarge and deform the hole by using the elasticity of the material to sleeve the hole on the shaft, and the hole is restored to generate the tightening force of the shaft so as to connect the two parts. The interference fit is used to secure the sensing pin sleeve 12 to prevent loosening during subsequent use.

If the detecting section is a cone, as shown in fig. 3 and fig. 4, fig. 3 is a non-working structure diagram of a hole position degree detecting device provided by the embodiment of the application; fig. 4 is a working state structure diagram of a hole position degree detection device according to an embodiment of the present application. The large diameter of the conical detection section is required to be larger than the size of a part to be detected, and the small diameter is required to be smaller than the size of the hole to be detected, so that when the detection section works, a part of the conical detection section can enter the hole to be detected, but cannot sink into the hole to be detected completely, and the detection result is more accurate by utilizing the gravity center of the conical detection section. When the detection section is conical, the spring 13 is installed in the first detection pin 111, the detection pin sleeve 10 is installed from bottom to top, and the tail end of the first detection pin 111 is fixed by the detection pin handle 12, so that the first detection pin 111 can freely slide along the detection pin sleeve 10 in the axial direction and cannot fall off.

In one embodiment, the second sensing pin 112 includes three parts, a guide section, a flange, and a sensing section. The diameter of the guide section is consistent with the inner diameter of the detection pin sleeve 10, the diameter of the flange is larger than the outer diameter of the spring 13, the detection section is funnel-shaped, the large diameter of the detection section is larger than the size of a pin to be detected of a part to be detected, and the small diameter of the detection section is smaller than the size of the pin to be detected. After the spring 13 is installed in the second detection pin 112, the whole body is installed in the detection pin sleeve 10 from bottom to top, and the tail end of the second detection pin 112 is fixed by the detection pin handle 12, so that the second detection pin 112 can freely slide along the detection pin sleeve within a certain stroke in the designated direction 10 and cannot be separated.

If the detecting section is funnel-shaped, as shown in fig. 5 and 6, fig. 5 is a non-working structure diagram of the pin position detecting device according to the embodiment of the present application; fig. 6 is a diagram showing an operational state of the pin position degree detecting device according to the embodiment of the present application. The big diameter of funnel needs to be greater than the size of the part pin that awaits measuring, and the small diameter needs to be less than the size of the pin that awaits measuring, makes the infundibulate detection section in the during operation, and infundibulate part can get into the pin that awaits measuring, but can not sink into the pin that awaits measuring completely, utilizes the focus of infundibulate to make the testing result more accurate. When the detection section is funnel-shaped, the spring is installed in the second detection pin 112, then the whole spring is installed in the detection pin sleeve 10 from bottom to top, and the detection pin handle 12 is fixed at the tail end of the second detection pin 112, so that the second detection pin 112 can freely slide along the detection pin sleeve 10 in the axial direction and cannot be separated.

As a specific explanation of this embodiment, the diameter of the guide section is identical to the inner diameter size of the detection pin sleeve 10, so that the guide section can pass through the detection pin sleeve 10 and cannot fall off due to oversized gaps; the diameter of the flange is larger than the outer diameter of the spring 13, so that the spring 13 cannot fall off from the guide section after the spring 13 is arranged in the guide section, and the spring 13 can provide compression force when the detection mechanism 11 works.

As a specific explanation of the present embodiment, the above-described detection pin handle 12 is attached to the end of the guide section remote from the detection section; a limiting block 9 is also arranged and connected to the second sliding component and is adjacent to the detection pin handle 12; the detecting pin handle 12 is in a circular-segment shape, and the inner diameter of the circular-segment shape is larger than the distance between the limiting block 9 and the detecting pin handle 12.

In this embodiment, the stopper 9 is provided on the side wall of the second portion of the second slider 5, and both can be connected by bolts. Specifically, the stopper 9 is provided with an eighth mounting hole, and the stopper 9 is fixed on the side wall of the second slider 5 through a screw and the eighth mounting hole. After the stopper 9 is mounted on the second slider 5, one end of the stopper 9 is required to be higher than the second slider 5, which aims to limit the movable stroke of the detection pin handle 12 at a specific angle so that a sufficient operation space is available for a specific step in the detection operation.

Wherein the detection pin handle 12 is in a shape of a circular segment. The circular shape is understood to mean that the horizontal transverse cut portion of the circular detection pin shank 12 forms a D-shaped structure with an arc length smaller than the circumference, and the cut portion forms a notch. Wherein, the distance between the cutting line and the circle center can be set to obtain the circular defect shapes with different gaps. For example, when the cutting line coincides with the center of the circle, half of the cutting is regarded as the semicircular detection pin handle 12, and when the cutting line has a distance from the center of the circle, the notch is smaller than half. At this time, the distance from the center of the circle to the cutting line is smaller than the inner diameter of the detection pin handle 12, so that the notch end of the detection pin handle 12 can move between the limiting block 9 and the detection pin handle 12; and the distance from the center of the circle to the arc length, that is, the inner diameter of the detection pin handle 12 is larger than the distance between the limiting block 9 and the detection pin handle 12, when the detection pin handle 12 is continuously rotated, the detection pin handle is limited to further movement by the size of the detection pin handle.

Specifically, the detection pin handle 12 is provided with a second through hole, the guide section of the detection mechanism 11 is embedded into the detection pin handle 12 through the second through hole, and the detection pin handle 12 is above the stopper 9. The purpose is that before the position degree detection device works, the arc edge of the detection pin handle 12 can partially cover a part of the limiting block 9, namely, the limiting block 9 can prevent the detection pin handle 12 from moving. When the position degree detection device works, the detection pin handle 12 rotates for a certain angle, then the trimming edge of the detection pin handle is parallel to the limiting block 9, and at the moment, the detection pin handle 12 does not cover the limiting block 9, namely the detection pin handle 12 can slide downwards.

Referring to fig. 3 and fig. 4 again, in the embodiment of the present application, specific detection steps when detecting a hole to be detected are:

first, the first jackscrew 7 and the first jackscrew 8 are loosened, the part to be detected is placed at the position to be detected, and at this time, the detection section of the first detection pin 111 is aligned with the position of the hole to be detected, which is designed in advance for the part.

Second, the detection pin handle 12 is rotated, so that the edge cutting of the detection pin handle 12 and the limiting block tend to be parallel and then are slowly loosened. At this time, the center of the first detection pin 111 will always keep the tendency to coincide with the hole to be measured due to the compression of the spring and the center of gravity of the cone.

Third, if the actual position of the part to be measured is inconsistent with the pre-designed position of the position to be measured, that is, the first detection pin 111 will move towards the actual position of the position to be measured, and at the same time, the first detection pin 111 will drive the second slider 5 and/or the slide 4 to move together.

Fourth, according to the scale mark of the slide 4 tangential to the first scale of the first slide 2 in the first direction, the scale mark of the slide 4 tangential to the second scale of the second slide 5 in the second direction, two scale values are read, and the vector of the two scale values is the position deviation value of the hole to be measured.

Judging whether the hole to be detected of the part is qualified or not through the calculated position degree deviation value and the preset position degree deviation range, and if the hole to be detected of the part is not qualified, adjusting and modifying according to the specific position degree value, so that the detection efficiency of the part is improved while damage to the part is not caused.

Referring to fig. 5 and 6 again, the present application further provides another embodiment, wherein the specific detecting steps when detecting the pin to be detected are as follows:

first, the first jackscrew 7 and the first jackscrew 8 are loosened, the part to be detected is placed at the position to be detected, and at this time, the detection section of the second detection pin 112 is aligned with the position of the characteristic pin designed in advance for the part.

Second, the detection pin handle 12 is rotated, so that the edge cutting of the detection pin handle 12 and the limiting block tend to be parallel and then are slowly loosened. At this point the center of the second sensing pin 112 will always remain in a trend of coincidence with the feature pin due to the compression of the spring and the center of gravity of the funnel shape.

Third, if the actual position of the feature pin of the part to be tested is inconsistent with the position of the pre-designed feature pin, the second detection pin 112 will move towards the actual position of the feature pin, and the second detection pin 112 will drive the second slider 5 and/or the slide 4 to move together.

Fourth, according to the scale mark of the slide 4 tangential to the first scale of the first slide 2 in the first direction, the scale mark of the slide 4 tangential to the second scale of the second slide 5 in the second direction, two scale values are read, and the vector of the two scale values is the position deviation value of the feature pin.

Judging whether the characteristic pin of the part is qualified or not through the calculated position degree deviation value and the preset position degree deviation range, and if the characteristic pin is not qualified, adjusting and modifying according to the specific position degree value, so that the detection efficiency of the part is improved while the part is not damaged.

The detection device converts the position degree of a hole/pin to be detected of a part to be detected into a scale value which can be directly read through the center automatic alignment function of the detection pin and the displacement of the detection mechanism 11 in the first direction and/or the second direction, so that the position degree deviation of the hole/pin is calculated. Judging whether the part is qualified or not according to a preset position deviation range, and if the part is unqualified, adjusting and modifying according to specific position values, so that the detection efficiency of the part is improved. The device detects the movement of the hole/pin to be detected through the detection mechanism 11, and no damage is caused to parts. The device assembled by the mechanical parts has lower production cost than computer modeling cost and high detection speed, so that the device can be produced in a large scale for batch detection. The positional detection apparatus is not limited to be fixed to a single mechanical structure, and can be applied to a plurality of mechanical structures and a plurality of scenes by changing the mounting position of the fixing base and the mounting surface of the fixing base.
