[0006] This invention provides a device for rapid inspection of outer diameter, which solves the problems of complex overall structure, difficulty in maintenance, low practicality, and low inspection efficiency caused by waiting for the piston rod of the clamping cylinder to move to the appropriate position during inspection.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A device for rapidly inspecting outer diameter includes a testing fixture and a mounting mechanism. The mounting mechanism includes a mounting base, a limiting frame with a limiting groove on its bottom inner wall, and a connecting frame fixed to one outer wall of the limiting frame. The connecting frame contains two fixing components. Each fixing component includes a mounting ring, a sliding rod slidably mounted within the mounting ring, a limiting block fixed to one outer wall of the sliding rod, a sliding plate fixed to one outer wall of the sliding rod, and a return spring abutting against one outer wall of the sliding plate. A limiting component is located below the testing fixture. This limiting component includes an "L"-shaped moving block, a mounting plate fixed to one outer wall of the moving block, two limiting posts fixed to the top outer wall of the mounting plate, and a locking block fixed to one outer wall of the moving block. A support component is located at one end of the mounting base. This support component includes a screw rod that passes through and is screwed to the bottom outer wall of the mounting base, and a support seat connected to the bottom outer wall of the screw rod via a bearing.

[0009] Preferably, the detection fixture has a U-shaped slot on one side and mounting slots on both outer walls of the detection fixture.

[0010] Preferably, the limiting frame is fixed on the outer wall of one side of the mounting base, and the limiting frame and the connecting frame are slidably installed on the outer wall of one end of the detection fixture.

[0011] Preferably, the mounting ring is fixed on the inner wall of one end of the mounting groove, the outer walls of both sides of the connecting frame are provided with limit holes, and the limit block is engaged in the limit hole. The sliding plate is slidably installed in the mounting groove, and the reset spring is sleeved in the mounting groove.

[0012] The above scheme moves the detection fixture along the inner wall of the connecting frame and the limiting frame, causing the connecting frame to press against the two limiting blocks. The movement of the limiting blocks drives the sliding rod and the sliding plate to move, which in turn presses against the reset spring. When the limiting block is located in the limiting hole on the connecting frame, the tension of the reset spring causes the limiting block to be engaged in the limiting hole, thus realizing the quick connection between the detection fixture and the installation mechanism.

[0013] Preferably, the movable block is slidably fitted into the limiting groove, the top outer wall of the mounting base has two slide rails, and the two limiting posts are slidably fitted into the two slide rails. The upper outer walls of the two limiting posts are screwed with fastening nuts. A support plate is fixedly provided on the outer wall of one bottom end of the movable block, and an arc-shaped fixing groove is provided on the outer wall of one side of the locking block.

[0014] With the above solution, place the vernier caliper on the detection fixture, fix the movable part of the vernier caliper on the detection fixture, then make two sample blocks with the maximum outer diameter and the minimum outer diameter. One end of the vernier caliper contacts one side of the moving block, and then push the maximum outer diameter sample block into the card slot of the detection fixture. The stop position indicated by the inner diameter measuring end at one end of the vernier caliper is the maximum outer diameter of the detection fixture corresponding to this sample block, and make a mark. The same applies to the minimum outer diameter. In actual inspection, place the circular part on the moving block and contact the clamping block, and then push the moving block. If the inner diameter measuring end of the vernier caliper is between the maximum outer diameter and the minimum outer diameter, it is qualified.

[0015] Preferably, a knob is fixedly installed on the outer wall of the top end of the screw rod, an installation hole is opened on the outer wall of the bottom of the installation seat, and the support seat is embedded in the installation hole.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. There are provided a detection fixture, an installation mechanism and a fixing component. Move the detection fixture along the inner walls of the connecting frame and the limiting frame, so that the connecting frame presses two limiting blocks. The movement of the limiting blocks drives the movement of the sliding rod and the sliding plate, and then presses the reset spring. When the limiting blocks are located in the limiting holes on the connecting frame, the limiting blocks are clamped in the limiting holes under the action of the tension of the reset spring, realizing the quick connection of the detection fixture and the installation mechanism, enabling the quick replacement and connection of the detection fixture. The overall structure is simple, easy to maintain, and improves the practicability.

[0018] 2. There is provided a limiting component. Place the vernier caliper on the detection fixture, fix the movable part of the vernier caliper on the detection fixture, then make two sample blocks with the maximum outer diameter and the minimum outer diameter. One end of the vernier caliper contacts one side of the moving block, and then push the maximum outer diameter sample block into the card slot of the detection fixture. The stop position indicated by the inner diameter measuring end at one end of the vernier caliper is the maximum outer diameter of the detection fixture corresponding to this sample block, and make a mark. The same applies to the minimum outer diameter. In actual inspection, place the circular part on the moving block and contact the clamping block, and then push the moving block. If the inner diameter measuring end of the vernier caliper is between the maximum outer diameter and the minimum outer diameter, it is qualified, which can quickly detect the outer diameter of a single batch of circular parts and improve the detection efficiency.

[0019] In summary, the present utility model can realize the quick replacement and connection of the detection fixture, has a simple overall structure, is easy to maintain, improves the practicability, can quickly detect the outer diameter of a single batch of circular parts, and improves the detection efficiency.

[0029] Example 1, referring to Figure 1-5A device for rapidly inspecting outer diameter includes a testing fixture 1 with a U-shaped slot on one side and a mounting mechanism 2. The testing fixture 1 has mounting grooves 11 on both outer walls. The mounting mechanism 2 includes a mounting base 201, a limiting frame 202 with a limiting groove on its bottom inner wall, and a connecting frame 203 fixed to one outer wall of the limiting frame 202. The limiting frame 202 is fixed to one outer wall of the mounting base 201. The limiting frame 202 and the connecting frame 203 are slidably mounted on one outer wall of the testing fixture 1. The connecting frame 203 contains two fixing components 3. The fixing component 3 includes a mounting ring 301, a slide rod 302 slidably mounted in the mounting ring 301, a limiting block 303 fixed on the outer wall of one end of the slide rod 302, a sliding plate 304 fixed on the outer wall of one end of the slide rod 302, and a return spring 305 abutting against the outer wall of one side of the sliding plate 304. The mounting ring 301 is fixed on the inner wall of one end of the mounting groove 11. Limiting holes are opened on both outer walls of the connecting frame 203. The limiting block 303 is engaged in the limiting hole. The sliding plate 304 is slidably mounted in the mounting groove 11. The return spring 305 is sleeved in the mounting groove 11.

[0030] Example 2, refer to Figure 1 and Figure 6-7 A device for quickly inspecting outer diameter also includes a limiting component 4. The limiting component 4 includes an "L"-shaped movable block 401, a mounting plate 402 fixed to the outer wall of one end of the movable block 401, two limiting posts 403 respectively fixed to the top outer wall of the mounting plate 402, and a locking block 405 fixed to the outer wall of one side of the movable block 401. The movable block 401 is slidably fitted in the limiting groove. Two slides are opened on the top outer wall of the mounting base 201. The two limiting posts 403 are slidably fitted in the two slides. A fastening nut is screwed onto the upper outer wall of each of the two limiting posts 403. The outer wall of the bottom end of the movable block 401 is... A support plate 404 is fixedly provided. A fixed groove with an arc structure is opened on one side of the outer wall of the locking block 405. A support component 5 is provided at one end of the mounting base 201. The support component 5 includes a screw 501 that passes through and is screwed to the bottom outer wall of the mounting base 201 and a support seat 502 that is connected to the bottom outer wall of the screw 501 through a bearing. A knob is fixed on the top outer wall of the screw 501. An installation hole is opened on the bottom outer wall of the mounting base 201. The support seat 502 is embedded in the installation hole. During testing, the screw 501 is rotated so that the bottom of the support seat 502 contacts the table surface of the testing table, so that the whole is stably placed on the table surface of the testing table.

[0031] Working principle: Rotating screw 501 causes the bottom of support base 502 to contact the table surface of the testing station, ensuring the entire unit is stably placed on the testing station surface. A vernier caliper is placed on testing fixture 1, with its movable part fixed to the fixture. Two sample blocks with the maximum and minimum outer diameters are then prepared. One end of the vernier caliper contacts one side of the movable block. The sample block with the maximum outer diameter is then pushed into the slot of testing fixture 1. The point where the inner diameter measuring end of the vernier caliper stops indicates the maximum outer diameter of the sample block corresponding to that testing fixture, and this point is marked. The same applies to the minimum outer diameter. In actual inspection, a circular component is placed on movable block 40. 1. The measuring end of the vernier caliper is positioned between the maximum and minimum outer diameters, and then the measuring end of the vernier caliper is pushed to contact the locking block 405. This indicates that the caliper is qualified. The measuring fixture 1 moves along the inner wall of the connecting frame 203 and the limiting frame 202, causing the connecting frame 203 to press the two limiting blocks 303. The movement of the limiting blocks 303 drives the sliding rod 302 and the sliding plate 304 to move, thereby pressing the return spring 305. When the limiting block 303 is located in the limiting hole on the connecting frame 203, the limiting block 303 is locked in the limiting hole under the tension of the return spring 305, thus realizing the quick connection between the measuring fixture 1 and the mounting mechanism 2.
