Description

Technical Field

[0001] This utility model belongs to the field of mechanical parts inspection tool technology, specifically a mechanical parts inspection tool for multi-station synchronous inspection. Background Technology

[0002] After existing mechanical parts are manufactured, they need to be inspected to determine whether the product is qualified. Parts inspection is an important process that affects not only the quality of maintenance but also the cost of maintenance.

[0003] Chinese Patent No. CN217572570U discloses a flipping mechanism for mechanical parts inspection fixtures, including a device body. Several columns are fixedly connected around the upper surface of the device body. A through groove is provided on each adjacent side of the columns. A linear servo mechanism is arranged in the through groove. The linear servo mechanism includes a guide rail. The bottom of the guide rail is fixedly connected to the output end of a servo motor. A slider is slidably connected to the upper surface of the guide rail. Ball screws are slidably connected to both ends of the slider. A connecting plate is fixedly connected to the front of the slider. Several rotating clamping mechanisms are fixedly connected to the front of the connecting plate. The rotating clamping mechanism includes a motor mounting base. In this utility model, automatic batch inspection of small mechanical parts is realized through the set rotating clamping mechanisms, etc. The existing technical solutions mentioned above have the following drawbacks: the two sets of rotary clamping mechanisms can only be driven to move up and down synchronously through the precise synchronous cooperation of two sets of servo motors, and each set of rotary clamping mechanisms is driven by an independent rotary motor. This results in a large number of electrical equipment required for the device, thereby increasing the manufacturing cost of the device and reducing its cost-effectiveness. Therefore, we propose a multi-station synchronous inspection tool for mechanical parts. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 A multi-station synchronous inspection tool for mechanical parts includes a slide plate 11. Two sets of parallel finger pneumatic grippers 17 are evenly rotatably mounted on the front side of the slide plate 11. A support shaft 164 is fixedly mounted on the rear side of each parallel finger pneumatic gripper 17. The rear side of the support shaft 164 passes through the rear side of the slide plate 11 and is connected to a worm gear 163. Worms 161 mesh with the tops of the two sets of worm gears 163. When the worm gear 161 rotates, it drives the two sets of worm gears 163 to rotate. The two sets of worm gears 163, through the two sets of support shafts 164, drive the two sets of parallel finger pneumatic grippers 17 to rotate and flip, thereby driving the parallel finger pneumatic grippers 17 to rotate and flip. 7. The clamped mechanical parts are flipped over to achieve the effect of automatically detecting different sides of the mechanical parts. An internal threaded slider 15 is fixedly installed on the rear side of the slide plate 11. A screw 12 is screwed into the inner side of the internal threaded slider 15. A support sleeve 162 is uniformly rotated on the outer side of the worm gear 161. The support sleeve 162 is uniformly fixedly installed on the rear side of the slide plate 11 and supports the rotation of the worm gear 161 through the support sleeve 162. A second servo motor 16 is fixedly installed on the right side of the slide plate 11. The output end of the second servo motor 16 is connected to the right side of the worm gear 161 and drives the worm gear 161 to rotate through the second servo motor 16.

[0017] Two sets of first mounting holes are evenly distributed through the front side of the slide plate 11. The support shaft 164 is rotatably installed in the first mounting holes. A base 111 is placed at the bottom of the slide plate 11. A gantry frame 1 is fixedly installed on the top of the base 111. A second mounting hole is opened on the top of the base 111. A first servo motor 13 is fixedly installed on the top of the gantry frame 1. The bottom of the output end of the first servo motor 13 passes through the bottom of the gantry frame 1 and is connected to the top of the screw 12. The bottom of the screw 12 is set in the second mounting hole. Two sets of T-shaped guide grooves are evenly distributed through the front side of the gantry frame 1. Two sets of T-shaped guide blocks 14 are evenly fixedly installed on the rear side of the slide plate 11. The T-shaped guide blocks 14 are slidably installed in the T-shaped guide grooves.

[0018] Working principle: Two sets of mechanical parts are placed on the base 111 for inspection. When the bottom of the mechanical parts needs to be inspected, the first servo motor 13 drives the screw 12 to rotate. The screw 12 drives the internal thread slider 15 to drive the slide plate 11 to move downward with the assistance of the T-shaped guide block 14. This causes the parallel finger pneumatic clamp 17 on the front side of the slide plate 11 to move downward to the outside of the part and clamp the mechanical part. At this time, the first servo motor 13 reverses to drive the parallel finger pneumatic clamp 17 to move upward, thereby driving the parallel finger pneumatic clamp... The mechanical part held by clamp 17 moves upward and separates from the base 111. At this time, the second servo motor 16 drives the worm gear 161 to rotate. When the worm gear 161 rotates, it drives the two sets of worm wheels 163 to rotate. The two sets of worm wheels 163 drive the two sets of parallel finger pneumatic clamps 17 to rotate and flip through the two sets of support shafts 164. This causes the mechanical part held by the parallel finger pneumatic clamps 17 to flip over. Then, the first servo motor 13 drives the flipped mechanical part to move downward to the base 111 through the parallel finger pneumatic clamps 17. This achieves the effect of automatically detecting different sides of the mechanical part.
