[0004] However, although the two-dimensional measurement method can guarantee the confirmation of the position accuracy between two holes, it is low in detection efficiency for products in batch production and has high requirements for the operation personnel, and is not suitable for industry promotion. CONTENT OF THE INVENTION

[0017] The first side wall is provided with through holes for the first guide post and the second guide post to pass through respectively, and the limiting piece abuts against the end of the first side wall away from the second side wall.

[0018] In some embodiments, the first guide post and the second guide post are respectively provided with a cylinder body and a telescopic post, one end of the telescopic post is connected with the connecting block, and the other end is slidably connected with the cylinder body.

[0040] The technical route of the present application is as follows:

[0041] Firstly, by the setting of the support 100, the connecting block 200 and the moving assembly 300, the setting of the first detection pin 210 and the second detection pin 220 on the connecting block 200 and the movement control of the connecting block 200 body by the moving assembly 300, it can be judged whether the first detection hole and the second detection hole meet the precision requirement according to the insertion condition of the first detection pin 210 to the first detection hole and the second detection pin 220 to the second detection hole when the connecting block 200 approaches the component to be measured 10, the original image modeling test is replaced by model test, the time spent in double-aperture measurement is reduced, and the work efficiency is improved.

[0043] Finally, in the elastic assembly, two ways are provided for the reciprocating movement of the first guide column 320 and the second guide column 330, wherein, the first embodiment provides an operation mode of reciprocating movement of the first guide column 320 and the second guide column 330 driven by manual operation, and the second embodiment provides an operation mode of reciprocating movement of the first guide column 320 and the second guide column 330 realized by the integration of the cylinder body 360 and the telescopic column 370, through the automatic control mode of motor, pneumatic, etc., so that the present application can be adapted to various application scenarios.

[0044] The implementation of the present application reduces the double-aperture measurement time, improves the work efficiency, and reduces the measurement difficulty.

[0045] The embodiments of the present application are described below.

[0046] Embodiment One

[0047] As shown in the figure, the embodiment provides a measuring device, comprising: Figure 1

[0048] a support 100, the support 100 is provided with a containing part for supporting a component 10 to be measured, and the component 10 to be measured is provided with at least a first hole to be measured and a second hole to be measured;

[0049] a connecting block 200, the connecting block 200 is connected to the support 100;

[0050] a moving assembly 300, the moving assembly 300 is arranged at the end of the connecting block 200 away from the component 10 to be measured, and the moving assembly 300 is used to drive the connecting block 200 to approach or move away from the component 10 to be measured;

[0051] wherein the connecting block 200 is provided with a first detection pin 210 corresponding to the first hole to be measured and a second detection pin 220 corresponding to the second hole to be measured;

[0052] When the position accuracy between the first hole to be measured and the second hole to be measured meets the requirements, the first detection pin 210 is inserted into the first hole to be measured, and the second detection pin 220 is inserted into the second hole to be measured.

[0053] Specifically, in the embodiment, the component 10 to be measured is placed in the support 100 through the containing part, and the first hole to be measured and the second hole to be measured on the component 10 to be measured are located outside the support 100, which is convenient for the subsequent insertion detection of the first detection pin 210 and the second detection pin 220, and preferably, the first detection hole and the second detection hole are located at the top of the component 10 to be measured; the connecting block 200 is connected to the support 100 through the moving assembly 300, and the connecting block 200 is arranged opposite to the component 10 to be measured, under the control of the moving assembly 300, the connecting block 200 can approach or move away from the component 10 to be measured, when the connecting block 200 approaches the component 10 to be measured, if the first detection pin 210 and the first hole to be measured can be smoothly inserted, and the second detection pin 220 and the second hole to be measured can be smoothly inserted, it proves that the position between the first hole to be measured and the second hole to be measured meets the accuracy standard, if any of the first detection pin 210 and the second detection pin 220 cannot be inserted into the corresponding hole to be measured, it proves that the position between the first hole to be measured and the second hole to be measured does not meet the accuracy standard.

[0054] ​It can be seen that by the above technical scheme, the measuring device provided by the present disclosure replaces the original two-dimensional image modeling method with a model comparison method, so that the operator only needs to compare the set model with the measured component 10, greatly reducing the time spent in measuring the measured component 10 and improving the work efficiency. The measuring device uses the support 100 as a base, which has a containing part for supporting the measured component 10 and is connected with the connecting block 200 for carrying the first detection pin 210 and the second detection pin 220. The connecting block 200 and the measured component 10 control the distance between them through the movement assembly 300, that is, when the position accuracy between the first detection pin 210 and the second detection pin 220 meets the position accuracy between the first measured hole and the second measured hole of the measured component 10, the first detection pin 210 can be inserted into the first measured hole and the second detection pin 220 can be inserted into the second measured hole when the connecting block 200 approaches the measured component 10. The operator can use this as a reference to judge whether the position accuracy between the first measured hole and the second measured hole of the measured component 10 meets the demand. It can be seen that the whole test process reduces the cumbersome parts such as two-dimensional image acquisition and equipment debugging. The operator only needs to compare the plurality of measured components 10 produced in batches one by one to realize the measurement between the two apertures, which greatly improves the work efficiency.

[0055] It should be noted that the measuring device in the present embodiment is not limited to the position test between two holes. The designer can measure the number and position of the holes according to the actual needs, set detection pins at corresponding positions of the connecting block 200, and control the movement assembly 300 to achieve the insertion detection described above.

[0056] Further, the support 100 is provided with a mounting groove 101, which includes a first side wall 102 and a second side wall 103, and a U-shaped structure is formed between the first side wall 102 and the second side wall 103.

[0057] The connecting block 200 moves in the mounting groove 101 through the movement assembly 300.

[0058] Specifically, the support 100 is provided with a mounting groove 101 for the movement of the connecting block 200. The mounting groove 101 forms a U-shaped structure through the arrangement of the first side wall 102 and the second side wall 103, which can provide sufficient space for the movement of the connecting block 200, and the relative arrangement of the first side wall 102 and the second side wall 103 can also limit the movement of the connecting block 200.

[0059] Further, the movement assembly 300 includes a handle 310, a first guide column 320, and a second guide column 330. The handle 310 penetrates the first side wall 102 from the outside of the mounting groove 101 and is connected with the connecting block 200.

[0060] The first guide post 320 and the second guide post 330 are respectively connected between the first side wall 102 and the connecting block 200.

[0061] Specifically, the first sidewall 102 is provided with a through hole for the handle 310 to pass through. The handle 310 passes through the first sidewall 102 through the through hole and connects to the connecting block 200, so that the handle 310 can drive the connecting block 200 to move within the mounting groove 101. At the same time, in order to increase the stability of the connecting block 200 during movement, a first guide post 320 and a second guide post 330 are connected to the first sidewall 102 and the connecting block 200. While the handle 310 drives the connecting block 200 to move back and forth, the first guide post 320 and the second guide post 330 move synchronously with the movement of the connecting block 200. Through the three-point support method, the movement of the connecting block 200 is more stable, avoiding changes in angle and displacement deviation of the connecting block 200 during movement, and ensuring the accuracy of subsequent measurements.

[0062] By implementing the above technical solution, the connecting block 200 can move normally within the mounting slot 101, and the stability of the connecting block 200 during movement can be guaranteed.

[0063] Furthermore, both the first guide post 320 and the second guide post 330 include a post body 340 and a limiting member 350, with the limiting member 350 located at the end of the post body 340 away from the second side wall 103.

[0064] The first sidewall 102 is provided with through holes for the first guide post 320 and the second guide post 330 to pass through, and the limiting member 350 abuts against the end of the first sidewall 102 away from the second sidewall 103.

[0065] In this embodiment, the operator manually moves the connecting block 200 to achieve the precision measurement between the holes of the component under test 10. That is, the connecting block 200 is moved by the handle 310, and the connecting block 200 drives the first guide post 320 and the second guide post 330 in a coordinated manner to control the connecting block 200. Throughout the process, the moving distance needs to be limited to avoid the connecting block 200 from colliding with the component under test 10.

[0066] Depend on Figure 1 It can be seen that one end of the first guide post 320 and the second guide post 330 can be limited by connecting with the connecting block 200, while the other end needs to be set with a corresponding limiting component to prevent it from sliding out of the first side wall 102.

[0067] Specifically, the limiting piece 350 is annularly arranged, so that when the first guide column 320 and the second guide column 330 move to the appropriate position with the connecting block 200, the limiting piece 350 can abut against the end of the first side wall 102 away from the second side wall 103, avoiding that the moving distance is too large during the process that the operator pushes the connecting block 200 using the handle 310.

[0068] It can be seen from the technical solutions described above that the movement distance of the connecting block 200 is limited by the double limiting, one is the U-shaped structure in the installation groove 101, which realizes the preliminary limiting when the connecting block 200 moves to the test area, and the other is the abutment between the limiting piece 350 and the end of the first side wall 102 away from the second side wall 103, which realizes the secondary limiting by the first guide column 320 and the second guide column 330, avoiding the risk that the first detection pin 210 and the second detection pin 220 change positions when the connecting block 200 contacts the second side wall 103 after the operator continuously applies force due to improper operation.

[0069] Further, the handle 310 and the outer wall of the first side wall 102 are connected with the elastic piece.

[0070] In the embodiment, the elastic piece is a reciprocating spring, which is annularly arranged outside the handle 310 and connected between the handle 310 and the outer wall of the first side wall 102. After the first detection pin 210 and the second detection pin 220 detect the position precision between the first to-be-measured hole and the second to-be-measured hole, the handle 310 can be restored to the original position without human operation by the elastic force of the reciprocating spring, further reducing the labor intensity of the operator.

[0071] Further, the end of the first detection pin 210 and the second detection pin 220 towards the to-be-measured component 10 is curved.

[0072] The curved surface can avoid scratches on the to-be-measured component 10 when the first detection pin 210 and the second detection pin 220 contact other parts of the to-be-measured component 10 when the position precision between the first to-be-measured hole and the second to-be-measured hole does not meet the requirements. The curved surface of the first detection pin 210 and the second detection pin 220 towards the to-be-measured component 10 is also wrapped with soft materials such as foam and sponge, which can further reduce the probability of scratches.

[0073] Further, the first detection pin 210 and the second detection pin 220 are detachably connected to the connecting block 200.

[0074] The first detection pin 210 and the second detection pin 220 can be detachably connected to the connecting block 200 in the form of threaded connection, plug-in or clamping, so that the positional relationship of the first detection pin 210 and the second detection pin 220 can be adjusted, and then the connecting block 200 can adapt to the position requirements between different double holes, thereby increasing the applicable scenarios of the product.

[0075] Further, the accommodating portion is provided with a positioning groove 104, and the positioning groove 104 is matched with the component to be measured 10, and the component to be measured 10 is plugged into the positioning groove 104.

[0076] Further, the positioning groove 104 is a square structure.

[0077] In the embodiment, the accommodating portion is provided in the form of a groove body of the positioning groove 104, which not only facilitates the placement of the component to be measured 10, but also is simple to process, and the fixation between the component to be measured 10 and the support 100 can be realized by clamping between the sidewalls of the groove body.

[0078] It should be noted that the positioning groove 104 is provided in a square structure, which is suitable for the plate-shaped component to be measured 10.

[0079] Embodiment Two

[0080] In the embodiment one, the first guide column 320 and the second guide column 330 of the moving assembly 300 are limited by abutting from the outside of the first sidewall 102, and another technical solution for limiting from the structure setting of the first guide column 320 and the second guide column 330 is provided in the embodiment, which is as follows:

[0081] As shown in Figure 2 In the embodiment, the first guide column 320 and the second guide column 330 are respectively provided with a cylinder body 360 and a telescopic column 370, one end of the telescopic column 370 is connected with the connecting block 200, and the other end is slidingly connected with the cylinder body 360.

[0082] The cylinder body 360 is internally provided with a sliding groove 361, and the end of the telescopic column 370 facing the sliding groove 361 is respectively provided with a protruding block 371, which is used for limiting the moving distance of the telescopic column 370 towards the component to be measured 10.

[0083] Through the cooperation between the protruding block 371 and the sliding groove 361, the telescopic column 370 can be telescopic moved along the outside of the cylinder body 360, and at the same time, the protruding block 371 abuts against the inner wall of the cylinder body 360 when it moves to the end point of the sliding groove 361, so as to realize the limiting effect.

[0084] It should be noted that the structure of the cylinder body 360 and the telescopic column 370 can also be set in the form of hydraulic transmission or pneumatic transmission, so as to realize the effect of automatic control measurement.
