The shell 20 is symmetrically arranged along the center line, and two connecting blocks 30 are also symmetrically arranged on the shell 20. When performing size detection on the part, due to the presence of a large number of curved surfaces on the edge of the part, the original manual measurement method is likely to cause inaccurate readings and errors. Utility Model Content
[0004] In order to facilitate the measurement of such symmetrical parts and determine whether the part dimensions meet the standards, the present application provides a synchronous centering testing mechanism.

[0007] By adopting the above technical solution, when it is necessary to measure whether the size of the parts meets the standards, the parts of standard sizes are placed on the placement rack, and then the parts are centered by the centering component and limited by the limiting component. After the parts are positioned, the positions of the micrometers are adjusted so that the heads of the micrometers can abut against the parts, and then the micrometers are fixed, and the data of each micrometer at this time is recorded. Then the parts of standard sizes are removed, and the parts to be measured are reinstalled on the placement rack, and the parts are centered by the centering component and limited by the limiting component. After the parts are positioned, the data of each micrometer at this time is read and compared with the standard data to determine whether the part size meets the standards, which effectively reduces manual measurement errors and facilitates the measurement of such symmetrical parts to determine whether the part size meets the standards.
[0008] Preferably, the placement rack comprises a connecting column fixedly mounted on the mounting seat, and a placement block fixedly mounted on the connecting column, the connecting block can be inserted into the placement block, and the micrometer is mounted on the connecting column.
[0009] By adopting the above technical solution and setting the connecting column and the placement block, when a part needs to be placed, the user can insert the connecting block on the part into the placement block to complete the placement of the part on the placement rack, making it easier to place the part stably.

[0012] Preferably, the limiting assembly comprises a limiting rod rotatably connected to the mounting seat, and an abutment column mounted on the limiting rod, and the mounting seat is provided with a driving member for driving the limiting rod to rotate.
[0013] By adopting the above technical solution, when a part needs to be limited, the user can drive the limiting rod to rotate through the driving member, so that the abutting column on the limiting rod abuts against the part, thereby tightening the part to limit the position.
[0014] Preferably, a flexible abutment head is fixedly connected to the abutment column.
[0015] By adopting the above technical solution and setting the flexible abutment head, the damage to the parts during the abutment and positioning process can be effectively reduced.
[0016] Preferably, the driving member is a rotating handle rotatably connected to the mounting seat, the rotating handle is rotatably connected to a connecting rod, and one end of the connecting rod away from the rotating handle is rotatably connected to the limiting rod.
[0017] By adopting the above technical solution, through the arrangement of the rotating handle and the connecting rod, the user rotates the rotating handle, the rotation of the rotating handle drives the connecting rod to rotate, and the rotation of the connecting rod drives the limiting rod to rotate, thereby realizing the movement of the limiting rod.
[0018] Preferably, the centering component is fixedly mounted on the parallel jaw cylinder on the mounting seat, and an alignment block is fixedly mounted on the jaw of the parallel jaw cylinder. Two alignment blocks are provided, and the two alignment blocks are symmetrically arranged along the parallel jaw cylinder. One alignment block is provided on the jaw of one parallel jaw cylinder, and an adjusting member for adjusting the position of the alignment block is provided on the mounting seat.
[0019] By adopting the above technical solution, the user can adjust the position of the alignment block by adjusting the parts and clamp the parts from both ends of the parts.

[0020] Preferably, the adjusting member is an adjusting rod threadedly connected to the mounting seat, and the adjusting rod is rotatably connected to one of the alignment blocks.
[0021] By adopting the above technical solution and setting the adjusting rod and the symmetrical block, when it is necessary to adjust the position of the alignment block so that the alignment block abuts and clamps the part, the user can rotate the adjusting rod. The movement of the adjusting rod will drive an alignment block to move, thereby causing one jaw of the parallel jaw cylinder to move, driving the other jaw of the parallel jaw cylinder to move, causing the other alignment block to move as well, thereby clamping the part.

DETAILED DESCRIPTION
[0029] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.
[0030] The embodiment of the present application discloses a synchronous centering testing mechanism.
[0031] like Figure 1 and 2 As shown, a synchronous centering test mechanism includes a mounting seat 1, and a placement rack 2 for placing parts is fixedly connected to the mounting seat 1. In this embodiment, two placement racks 2 are provided, and the two placement racks 2 are respectively located on both sides of the part to support the part. The placement rack 2 includes a connecting column 21 and a placement block 22, and the connecting column 21 is connected to the mounting seat 1 by bolts, and the placement block 22 is installed on the connecting column 21 by bolts, and a concave groove is provided on the placement block 22. The connecting block 30 on the part can be inserted into the concave groove on the placement block 22, and the placement block 22 provides a certain degree of support to the part, thereby realizing the preliminary installation of the part. The placement rack 2 is also equipped with an abutment block 6 for abutting the part by bolts, and the abutment block 6 can be attached to the surface of the part. When in use, when it is necessary to place a part on the placement rack 2, the user needs to align the connecting block 30 on the part with the position of the concave groove on the placement block 22, and then move the part so that the connecting block 30 on the part is inserted into the concave groove, and the part is attached to the abutment block 6, thereby completing the placement of the part.
[0032] like Figure 1 and 2As shown, the mounting base 1 is provided with a centering assembly 4 for aligning parts, and the centering assembly 4 includes a parallel clamping jaw cylinder 41 and an alignment block 42. The parallel clamping jaw cylinder 41 is a prior art, and can be ventilated or moved to control the two clamping jaws on the parallel clamping jaw cylinder 41 to move in parallel, so that the two clamping jaws move toward each other or away from each other. There are two alignment blocks 42, one alignment block 42 is connected to one clamping jaw of the parallel clamping jaw cylinder 41 by bolts, and the two alignment blocks 42 are symmetrically arranged along the parallel clamping jaw cylinder 41. The mounting base 1 is also provided with an adjusting member for adjusting the position of the alignment block 42, and the adjusting member is an adjusting rod 10 threadedly connected to the mounting base 1 The adjusting rod 10 is rotatably connected to an alignment block 42. When in use, the parallel clamping cylinder 41 is not connected to the air pipeline for use, but is mechanically driven. After the parts are placed, the user rotates the adjusting rod 10. The rotation of the adjusting rod 10 will cause the adjusting rod 10 to move on the mounting seat 1, thereby causing an alignment block 42 to move. The movement of an alignment block 42 will drive one clamping jaw of the parallel clamping cylinder 41 to move, thereby causing the other clamping jaw of the parallel clamping cylinder 41 to move, thereby causing the other alignment block 42 to move, so that the two alignment blocks 42 are close to each other, the parts are clamped and centered, and the position of the parts is corrected.
[0033] like Figure 1 and 2 As shown, the mounting seat 1 is also provided with a limiting assembly 3 for limiting parts, and the limiting assembly 3 includes a limiting rod 31 and an abutment column 32. The limiting rod 31 is rotatably connected to the mounting seat 1. In this embodiment, two limiting rods 31 are provided, and the abutment column 32 is threadedly connected to the limiting rod 31. The end of the abutment column 32 away from the limiting rod 31 is clamped and fixed with a flexible abutment head 7. In this embodiment, three abutment columns 32 are provided on one limiting rod 31. The mounting seat 1 is also provided with a driving member for driving the limiting rod 31 to rotate. The driving member is a rotating handle 8 rotatably connected to the mounting seat 1. The position where the rotating handle 8 is hinged to the mounting seat 1 adopts a damping rotation so that the rotating handle 8 will not rotate due to its own gravity. The rotating handle 8 is rotatably connected to a connecting rod 9, and one end of the connecting rod 9 away from the rotating handle 8 is rotatably connected to the limiting rod 31, and the hinged position of the connecting rod 9 on the limiting rod 31 is different from the hinged position of the limiting rod 31 on the mounting base 1, so that when the user rotates the rotating handle 8, the connecting rod 9 will pull the limiting rod 31 to move. In this embodiment, the limiting rod 31 will be in a vertical state in the limited state, which can effectively reduce the deflection of the limiting rod 31 due to its own gravity. During use, when the parts are placed, the user rotates the rotating handle 8, thereby rotating the limiting rod 31, so that the limiting rod 31 abuts against the part to position the part, thereby completing the positioning of the part and correcting the position of the part.
[0034] like Figure 1 and2 As shown, the mounting seat 1, the placement frame 2, and the counterweight assembly are all provided with a micrometer 5 for measuring the size of the parts. In this embodiment, only the corresponding parts are tested, and the measuring end of the micrometer 5 is preliminarily ensured to be able to abut against the parts and be fixedly installed. Four micrometers 5 are provided on the mounting seat 1, including two micrometers 5 for measuring the size of the parts on both sides. Because the parts are centered and positioned, the readings of the micrometers 5 measuring the size of the parts on both sides should be the same, and a micrometer 5 for measuring the length of the parts after positioning is also included, which is used to determine the length of the parts. The micrometer 5 is used to measure the length of the rear end face of the part after positioning, and is used to determine whether the length of the end face of the part meets the standard. Three micrometers 5 are arranged on the placement rack 2, including two micrometers 5 for measuring the dimensions on both sides of the end face of the part. Because the part is centered and positioned, the readings of the micrometers 5 measuring the dimensions on both sides of the part should be the same. The micrometer 5 is also used to measure the length of the rear end face of the positioning. The micrometer 5 is arranged opposite to the micrometer 5 on the mounting seat 1 for measuring the length of the rear end face of the part after positioning, so as to facilitate the measurement of the end face data of the part.
[0035] The implementation principle of the embodiment of the present application is: when it is put into actual use, the user first places the parts of standard size on the placement rack 2, and uses the centering component 4 to center the parts and the limiting component 3 to limit the parts, and reads the readings of each micrometer 5 at this time, and records the data at this time as the standard size for comparison. Then the user removes the parts of standard size, installs the parts to be tested on the placement rack 2, and uses the centering component 4 to center the parts and the limiting component 3 to limit the parts, reads the readings of each micrometer 5 at this time and compares them, so as to obtain whether the part size meets the standard.
[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
