[0002] After the casting is completed, corresponding surface treatment and detection steps need to be carried out to meet the quality requirements, for example, a caliper workpiece, referring to Figure 6 , including a main circular body 14, the main circular body 14 is integrally formed with an extension rod 11 on both sides, the main circular body 14 is integrally formed with a jaw block 12 at the two extension rods 11, and the jaw block 12 is formed with two convex corners 13 away from the main circular body 14. A series of surface processing and detection work need to be carried out on the caliper workpiece.

[0003] The existing aluminum alloy casting automatic production line with publication number CN112122593A is driven by a manipulator to sequentially carry out cooling, vibration shakeout, cutting and other pre-processing, and then the workpiece is placed into a shot blasting machine for surface burr removal processing, and then the workpiece is detected.

[0004] For the related technology in the above, the manipulator drives the workpiece to move for processing of several processes, which is more suitable for large-volume castings, while for small-volume and large-quantity workpieces such as calipers, using a manipulator to sequentially process and detect the surface is too low in processing efficiency. SUMMARY

[0005] In order to improve the processing efficiency of the caliper workpiece, the present application provides a caliper processing production line.

[0006] The caliper processing production line provided by the present application adopts the following technical scheme.

[0007] A caliper processing production line, comprising a feeding rack, a shot blasting machine located on one side of the feeding rack, a feeding hopper rotatably connected to the feeding rack and capable of pouring the workpiece into the shot blasting machine, a hopper power source provided on the feeding rack and driving the feeding hopper to rotate, a vibrating screen bed provided at the discharge port of the shot blasting machine, a main conveyor belt provided at the discharge end of the vibrating screen bed, a rotating material disc provided at the discharge end of the main conveyor belt and capable of rotating to receive the workpiece, a plurality of sub-conveying parts close to the rotating material disc, and a detection device provided on the side of each sub-conveying part and capable of detecting the integrity of the workpiece.

[0008] By adopting the above technical scheme, a certain number of workpieces are placed into the feeding hopper and then poured into the shot blasting machine, the workpieces after shot blasting are poured onto the vibrating screen bed, so that the shot and the workpiece are separated, and the workpieces are conveyed onto the rotating material disc on the main conveyor belt, and at the same time, the corresponding detection work is carried out, which helps to improve the processing efficiency of a large number of small-volume workpieces.

[0009] Optionally, the detection device comprises a base plate arranged at the side of the sub-conveying part, two positioning blocks fixedly connected to the base plate and allowing the extension rods to slide into, two pressing pieces rotatably connected to the base plate and abutting against the extension rods away from the positioning blocks, a guide rod fixedly connected to the base plate, a detection block slidably connected to the guide rod and capable of abutting against the convex corners, and a prompting piece arranged at one side of the sub-conveying part and capable of prompting when the detection block abuts against the two convex corners.

[0010] By adopting the above technical scheme, the caliper workpiece is placed on the base plate, the extension rods are put into the positioning blocks, then the two pressing pieces are rotated to abut against the upper portions of the extension rods, and then the detection block is moved downward to abut against the convex corners, so that when the two convex corners are not damaged, the current can form a loop through the caliper workpiece to trigger the prompting piece to prompt, and otherwise the surface convex corners are broken and do not meet the requirements.

[0013] Optionally, the guide rod is fixedly connected with a limit moving block capable of abutting against the detection block, and the limit moving block is flush with the intact convex corner.

[0014] By adopting the above technical scheme, the detection block can only move downward to a predetermined position, so that when both of the two convex corners are broken, the detection block cannot abut against the convex corners, so that the condition that both of the two convex corners of the workpiece are broken at the same time can be determined.

[0015] Optionally, the base plate is rotatably connected with two slave rotating columns away from the positioning blocks, the slave rotating columns are coaxially fixedly connected to the corresponding pressing pieces, each of the surfaces of the two slave rotating columns is formed with a helical groove, a driving rod is slidably connected in the helical groove along the track of the helical groove, the driving rod is fixedly connected with a synchronous rod, the base plate is fixedly connected with a power cylinder for driving the synchronous rod to move close to or away from the base plate to rotate the slave rotating columns.

[0016] By adopting the above technical scheme, the power cylinder can drive the two slave rotating columns to rotate synchronously, so that the two pressing pieces can synchronously abut against the corresponding extension rods, and manual detection operation is not needed.

[0018] Through the above technical scheme, the detection block can be driven to move while the power cylinder drives the pressing piece to rotate, so that the worker only needs to place the workpiece on the bottom plate and does not need to perform subsequent detection work again.

[0019] Optionally, a plurality of material frames are fixedly connected to the periphery of the material rotating disc, and a pushing plate is slidingly connected to each material frame corresponding to the material rotating disc.

[0022] Through the above technical scheme, the pushing plate can stably move.

[0023] Optionally, a pneumatic marking machine is arranged on one side of the sub-conveying part close to the material rotating disc, and an ultrasonic flaw detector is arranged on one side of the sub-conveying part away from the pneumatic marking machine.

[0024] Through the above technical scheme, the workpiece sent by the material rotating disc can be first marked, then the corner breakage is detected, and then the crack detection is performed, so that the quality of the shipped workpiece is guaranteed.

[0025] Optionally, each sub-conveying part includes a main frame and two short conveying belts arranged on the main frame, the two short conveying belts are close to each other at both conveying ends, and the detection device and the ultrasonic flaw detector are correspondingly close to the two short conveying belts.
