Description

Technical Field

[0001] The present invention relates to the technical field of machining inspection tools, and specifically provides a multi-station machining part inspection tool. Background Technique

[0002] An inspection tool is a tool used to control various dimensions of a product and check the dimensional and positional characteristics of a workpiece, and plays a key role in ensuring product quality in machining. It can accurately measure parameters such as the size, shape, and position of a workpiece, promptly detect machining deviations and defects, and ensure that the product meets the design requirements and standards. Compared with traditional measurement methods, it can complete the detection of multiple parameters in a short time, improve the detection efficiency, and thus enhance the production efficiency. By promptly detecting unqualified products, it avoids the continued investment in unqualified products during subsequent machining processes and reduces production costs.

[0003] For example, in a part inspection tool with the publication number CN217687060U, by providing a clamping plate and an inspection tool mechanism, the clamping plate is installed on a rotating shaft by a moving block A, so that the part that needs to be operated by the inspection tool is placed between the clamping plates. Rotate the operation handle to control the two groups of clamping plates to move inward to clamp and fix the part. By installing the inspection tool mechanism on a support plate and adjusting the height of the support plate until the inspection tool mechanism contacts the surface of the part, and using the effect that the inspection tool mechanism has a flatness scale display, push the operation table until the part moves. When the flatness of the part is uneven, the inspection tool mechanism will perform scale display, effectively realizing the flatness inspection operation of the flatness inspection tool on the part and improving the qualified rate of parts leaving the factory.

[0004] When this patent detects parts, it is necessary to rotate the threaded rod in the fixture to perform threaded transmission with two groups of clamping blocks, thereby driving the two groups of clamping blocks to move to clamp the parts, and then detect the parts through the detection mechanism at the top. However, when the clamping blocks clamp the parts, they will block a part of the position of the parts. Therefore, when the detection mechanism detects the parts, it cannot detect the blocked part. At the same time, since the bottom of the part contacts the top plane of the fixture, the bottom of the part will also be blocked. When there are defects in the bottom and the blocked part on the outside of the part, it is difficult for the detection mechanism to detect these parts, and it is necessary to re-clamp the parts and then perform secondary detection, and the operation is relatively cumbersome, making it difficult to quickly detect the parts.

[0020] Compared with the prior art, the multi-station machining parts inspection fixture has the following beneficial effects: 1. The multi-station machining parts inspection fixture drives the bearing sleeve and cylinder c to move upward by starting cylinder b. When the gear body outside cylinder c is about to mesh with the rack rod, it will drive cylinder c to rotate, thereby driving the V-block a at one end and the clamped parts to rotate. The bottom of the rotated parts will be exposed. At this time, the bottom can be inspected by the detection mechanism to prevent the defects at the bottom of the parts from being missed. By starting cylinder c, the V-block a is driven to disengage from the clamping of the parts, and then the cylinder d is started to drive the V-block b to clamp the parts.

[0021] 2. This multi-station machining parts inspection fixture, when detecting defective products, will push the parts into the collection box through cylinder a. In order to prevent waste from accumulating on one side of the collection box and failing to fully utilize the space in the collection box, a set of driven gears are arranged on the inner side of the gear ring. When the rotating platform rotates, it will mesh with the driven gear through the gear ring, thereby driving the driven gear to rotate. The driven gear will drive the transmission rod at the bottom to rotate, so that it drives the connecting plate at the bottom to rotate. The connecting plate will slide in the strip groove inside the fixed plate through the cylindrical block at the bottom, thereby driving the fixed plate and the moving frame on one side to reciprocate. When the moving frame reciprocates, the waste in the top collection box is affected by the shaking and will be evenly spread in the collection box, thereby fully utilizing the space in the collection box. In this way, the waste entering the collection box can be evenly spread through the above operation, thereby storing more waste.

[0022] 3. When the detection mechanism of the multi-station machining parts inspection fixture is disassembled and maintained, the lever is pulled upward. When the lever moves, the rectangular rod and the protrusion are also moved. The protrusion slides in the spiral groove inside the rotating block, thereby driving the rotating block to rotate. The rotating block drives the toggle block to move to one side of the moving rod. Then the lever can be pulled to drive the rotating block to move together, so that the rotating block drives the toggle block to move the moving rod. The moving rod drives the clamping block at one end to move, squeeze the spring b on one side, and disengage it from the engagement with the three-axis robot arm. Then the mounting plate can be moved upward to drive the plug-in block to disengage it from the plug-in with the three-axis robot arm, and then the mounting plate can be taken out. In this way, the mounting plate on which the detection mechanism is installed can be quickly disassembled through the above operation, thereby facilitating the maintenance of the detection mechanism.

Inside the bearing sleeve 15, a cylinder c16 is rotatably connected. One end of the cylinder c16 is fixedly connected with a V-shaped block a17. One end of the cylinder c16 is provided with a flipping mechanism. At the bottom of the fixture table 12, a dislocation limiting mechanism is provided; the dislocation limiting mechanism includes a cylinder d18 fixedly connected to the inside of the fixture table 12. One end of the cylinder d18 is fixedly connected with a slider 29. The outside of the slider 29 is slidably connected with a moving block 19. Both sides of the moving block 19 are fixedly connected with round rods 20. Inside the fixture table 12, an inclined slot 21 matching the round rods 20 is opened. One end of the inclined slot 21 is connected with a straight slot 22. The straight slot 22 is opened inside the fixture table 12. The top of the moving block 19 is fixedly connected with a V-shaped block b23. Rubber pads are fixedly connected to one side of both the V-shaped block b23 and the V-shaped block a17; the flipping mechanism includes a gear body 24 fixedly connected to the outside of the cylinder c16. One side of the gear body 24 is provided with a rack bar 25. The bottom of the rack bar 25 is fixedly connected with the fixture table 12. One end of the cylinder c16 is fixedly connected with a fixed block 26. Inside the fixed block 26, a limiting rod 27 is slidably connected. A tapered slot 28 matching the limiting rod 27 is opened on one side of the fixed block 26. The fixed block 26 and the limiting rod 27 form a sliding structure. The gear body 24 and the rack bar 25 form a meshing transmission structure; the composite detection mechanism includes a vision camera 5 fixedly connected to the bottom of the mounting plate 4. One side of the vision camera 5 is provided with a laser sensor 6 and a contact gauge 7. The tops of the laser sensor 6 and the contact gauge 7 are fixed to the mounting plate 4; the driving mechanism includes a motor 8 fixedly installed at the bottom of the chassis 1. The output end of the motor 8 is fixedly connected with a driving gear 9. The outside of the driving gear 9 is meshed with a gear ring 10. The top of the gear ring 10 is fixedly connected with the rotating platform 2. Support rods 11 are fixedly connected to the four sides of the bottom of the rotating platform 2. The bottom of the support rods 11 is in rolling connection with the chassis 1 through balls. An annular groove matching the support rods 11 is opened on the top of the chassis 1. The driving gear 9 and the gear ring 10 form a meshing transmission structure.

[0027] During specific implementation, when fixing the components for the multi-station machining jig, the components are placed on the top of the fixture table 12. The positioning pins on the top of the fixture table 12 will position the components. Then, two sets of cylinders c16 are started to drive the V-shaped block a17 to move, so that the V-shaped block a17 clamps the workpiece. At this time, the components can be detected by the detection mechanism on one side of the three-axis robotic arm 3. After the detection mechanism performs the first detection on the outer shape of the components, in order to detect the bottom of the components, the cylinder b14 is started to drive the bearing sleeve 15 and the cylinder c16 to move upward. When the cylinder c16 starts to move, the fixing block 26 at one end will slide on the outside of the limiting rod 27, so as to limit the cylinder c16 and prevent the cylinder c16 from rotating at this time. When the gear body 24 on the outside of the cylinder c16 is about to engage with the rack bar 25, the fixing block 26 will disengage from the outside of the limiting rod 27. At this time, the engagement of the gear body 24 and the rack bar 25 will drive the cylinder c16 to rotate, thereby driving the V-shaped block a17 at one end and the clamped components to rotate as well. The bottom of the rotated components will be exposed. At this time, the detection mechanism can detect its bottom to prevent the defects existing at the bottom of the components from being missed in the detection. After the detection is completed, the cylinder b14 can be started to drive the cylinder c16 to move downward. When the gear body 24 disengages from the rack bar 25, the bottom of the part will be parallel to the plane on the top of the fixture table 12, and the tapered groove 28 on one side of the fixing block 26 will also be aligned with the limiting rod 27. The tapered groove 28 can facilitate the limiting rod 27 to pass through the fixing block 26. When the bottom of the components contacts the top of the fixture table 12, the detection of the bottom of the components can be completed; When it is necessary to detect the position blocked by the V-shaped block a17 during clamping, the cylinder c16 is started to drive the V-shaped block a17 to release the clamping of the components. Then, the cylinder d18 is started. The cylinder d18 will pull the moving block 19 to move, and the moving block 19 will slide in the inclined groove 21 through the round rods 20 on both sides, so that the moving block 19 and the V-shaped block b23 move upward. When the round rods 20 move into the straight groove 22, the V-shaped block b23 will no longer move upward. At this time, after the V-shaped block b23 contacts the components, it will clamp them. Then, the detection mechanism can detect the position clamped by the V-shaped block a17 on the components. After the detection is completed, the cylinder d18 can be started to drive the V-shaped block b23 to reset back into the fixture table 12. When the components are unqualified during the detection, the cylinder a13 can be started to push the components away from the top of the fixture table 12 to complete automatic sorting. Since the V-shaped block b23 is inside the fixture table 12 at this time, it will not block the movement of the components. Thus, through the above operations, the components can be comprehensively detected.

[0028] Please refer to Figure 1 、 Figure 2 and Figure 7The inner side of the gear ring 10 is meshed with a driven gear 30, and a transmission rod 31 is fixedly connected to the bottom of the driven gear 30. A connecting plate 32 is fixedly connected to the bottom of the transmission rod 31. A cylindrical block 33 is provided at the bottom of the connecting plate 32. A fixed plate 34 is slidably connected to the outer side of the cylindrical block 33. A strip groove matching the cylindrical block 33 is provided inside the fixed plate 34. A moving frame 35 is welded and fixed to one side of the fixed plate 34. A collecting box 36 is abutted against one side of the moving frame 35. A slide rail 37 is slidably connected to the bottom of the moving frame 35. A bottom plate 38 is fixedly connected to the bottom of the slide rail 37. An adjusting mechanism is provided inside the connecting plate 32. A strip groove matching the slide rail 36 is provided at the bottom of the moving frame 35. The guide rail 37 is matched with the guide rail 37, the guide rail 37 and the movable frame 35 form a sliding structure, and the driven gear 30 and the gear ring 10 form an engaging transmission structure; the adjusting mechanism includes a threaded rod 39 movably connected to the connecting plate 32 through a bearing, the outer side of the threaded rod 39 is threadedly connected to a threaded block 40, the outer side of the threaded block 40 is slidably connected to the connecting plate 32, the bottom of the threaded block 40 is movably connected to the cylindrical block 33 through a rotating shaft, the cylindrical block 33 forms a rotating structure with the threaded block 40 through a rotating shaft, the threaded rod 39 and the threaded block 40 form a threaded transmission structure, the interior of the connecting plate 32 is provided with a guide groove matching the threaded block 40, and the threaded block 40 and the connecting plate 32 form a sliding structure.

[0029] In specific implementation, when the multi-station machining parts inspection fixture detects defective products, it will push the parts into the collection box 36 through the cylinder a13. In order to prevent waste from accumulating on one side of the collection box 36 and failing to fully utilize the space in the collection box 36, a set of driven gears 30 are arranged on the inner side of the ring gear 10. When the rotating platform 2 rotates, it will mesh with the driven gear 30 through the ring gear 10, thereby driving the driven gear 30 to rotate. The driven gear 30 will drive the transmission rod 31 at the bottom to rotate, so that it drives the connecting plate 32 at the bottom to rotate. The connecting plate 32 will slide in the strip groove inside the fixed plate 34 through the cylindrical block 33 at the bottom, thereby moving the fixed plate 34 and the moving frame 35 on one side to reciprocate. When the mobile frame 35 moves back and forth, the waste in the top collection box 36 is affected by the shaking and will be evenly spread in the collection box 36, so as to make full use of the space in the collection box 36. When it is necessary to adjust the shaking amplitude of the collection box 36 to adapt to waste materials of different weights, the threaded rod 39 and the threaded block 40 are rotated to perform threaded transmission, so as to drive the threaded block 40 and the cylindrical block 33 at the bottom to move. The rotation radius of the cylindrical block 33 after movement will change, so the moving range of the fixed plate 34 will also change, thereby changing the shaking amplitude of the mobile frame 35 and the collection box 36. In this way, the waste entering the collection box 36 can be evenly spread through the above operation, so as to store more waste materials.
