Description

Technical Field

[0001] This utility model relates to the field of expansion screw processing technology, and in particular to a fixture for processing expansion screws. Background Technology

[0002] An expansion bolt is a type of bolt that uses the cooperation of a screw and an expansion tube to create strong friction within the fixing body, thereby achieving a secure connection. It is commonly used to fix pipes, equipment, and accessories to walls, floors, or other structures. However, expansion bolts require clamps for fixing during the manufacturing process to facilitate the work of the workers.

[0003] However, since a large number of expansion screws need to be processed each time and the process takes a long time, most of the existing expansion screw processing fixtures on the market are not convenient for workers to collect the processed expansion screws, which increases the labor intensity of the workers.

[0004] Therefore, those skilled in the art have provided a fixture for machining expansion screws to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixture for processing expansion screws. The fixture uses two second cylinders below the processing table in the collection mechanism to act on the connecting block, causing the baffle to slide inside the moving groove. This changes the obstruction of the placement opening, aligning the discharge port and the placement opening to form a discharge channel, making it easier for workers to collect the processed expansion screws.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fixture for processing expansion screws includes a processing table, a clamping mechanism, and a collecting mechanism. The clamping mechanism is provided at the upper end of the processing table and includes multiple clamping plates. Multiple placement openings are provided in the middle of the upper end of the processing table. The collecting mechanism is provided inside the processing table and includes a baffle, two second cylinders, and a collecting frame. A moving groove is provided in the middle of the inside of the processing table. Multiple material dropping openings are provided at the upper end of each baffle. A connecting block is fixedly connected to the outer wall of the rear end of each baffle. The front ends of each of the second cylinders are fixedly connected to the processing table.

[0008] The output shaft of the second cylinder is fixedly connected to the connecting block. The middle of both sides of the lower end of the processing table is fixedly connected to the fixing block. The middle of the upper end of the outer wall of both sides of the collection frame is slidably connected to the fixing block. A fixing bolt is threadedly connected to the center of the outer wall of one side of the fixing block. Sliding grooves are opened on both sides inside the processing table. A support block is fixedly connected to the side of the clamping plate away from the center of the processing table.

[0009] Through the above technical solution, the two second cylinders under the processing table act on the connecting block, causing the baffle to slide inside the moving groove on the processing table, changing the obstruction of the placement opening on the processing table by the baffle, so that the material discharge port on the baffle is aligned with the placement opening, forming a material discharge channel, which facilitates the collection of the processed expansion screws.

[0010] Furthermore, a first cylinder is fixedly connected to the inner wall of the front end of the slide, a limiting block is fixedly connected to the output shaft of the first cylinder, a stop block is fixedly connected to the lower end of the support block on the side away from the center of the processing table, the stop block on the side away from the center of the processing table is in contact with the limiting block, and a return spring is fixedly connected to the lower end of the support block on the side close to the center of the processing table.

[0011] Through the above technical solution, the first cylinder drives the limiting block to move. The fixed block on the support block and the limiting block are in contact, so that the moving limiting block can push the clamping plate on the support block to move on the processing table. The return spring acts on the support block so that when the limiting block is not released from the block, the support block can drive the clamping plate to return to its original position. In this way, the space above the processing table is not occupied too much, which makes it convenient for the workers to process the expansion screws.

[0012] Furthermore, support columns are fixedly connected to the four corners of the lower end of the processing table, and a PLC control panel is fixedly connected to the middle of the outer wall of one side of the processing table.

[0013] The above technical solution allows the equipment to be stably placed on the ground by four support columns fixedly connected to the lower end of the processing table, improving the stability during operation. The PLC control panel fixedly connected to the processing table makes it easy for operators to control the operating status of the equipment.

[0014] Furthermore, the baffle slides inside the moving groove, and both sides of the lower end of the connecting block penetrate the moving groove to the outside of the processing table;

[0015] By using the above technical solution, by having the two sides of the lower end of the connecting block extend through the outside of the processing table and be fixedly connected to two second cylinders, the second cylinders can drive the baffle fixedly connected to the connecting block to move inside the moving groove.

[0016] Furthermore, the other side of the fixing bolt passes through the fixing block and is threadedly connected to the collection frame, and a handle is fixedly connected to the middle of the front outer wall of the collection frame;

[0017] The above technical solution allows the collection frame to be fixed when it slides into the fixing block by having one side of the fixing bolt pass through the fixing block and be threadedly connected to the collection frame. After the threaded connection between the fixing bolt and the collection frame is released, the collection frame can be easily removed using the handle.

[0018] Furthermore, the limiting blocks all slide inside the slide groove, and the lower ends of the supporting blocks all penetrate the processing table into the interior of the slide groove;

[0019] By using the above technical solution, by having the lower end of the support block penetrate into the interior of the slide groove opened in the processing table and be fixedly connected to the abutment block, the contact between the abutment block and the limiting block allows the moving limiting block to push the support block to move on the processing table.

[0020] Furthermore, the side of the return spring near the center of the processing table is fixedly connected to the inner wall of the slide groove;

[0021] By using the above technical solution, and by fixing the return spring on the support block to the inner wall of the slide groove, the support block can drive the clamping plate to return to its original position when the limiting block is not in contact with the abutment block.

[0022] This utility model has the following beneficial effects:

[0023] 1. The present invention proposes a clamp for processing expansion screws. By using two second cylinders under the processing table in the collection mechanism to act on the connecting block, the baffle slides inside the moving groove of the processing table, changing the obstruction of the placement opening on the processing table by the baffle, so that the material discharge port on the baffle is aligned with the placement opening, forming a material discharge channel, which makes it easier for workers to collect the processed expansion screws and reduces the labor intensity of workers.

[0024] 2. The present invention proposes a clamp for processing expansion screws. The first cylinder in the clamping mechanism drives the movement of the limiting block. The abutment fixedly connected to the support block and the limiting block are in contact, so that the moving limiting block can push the clamping plate on the support block to move on the processing table. The return spring acts on the support block so that when the limiting block is not released from the abutment, the support block can drive the clamping plate to return to its original position. Thus, it does not occupy too much space above the processing table, making it convenient for workers to process expansion screws. Attached Figure Description

The middle of the upper end of both sides of the outer wall of the collection frame 607 is slidably connected to the fixing block 606. A fixing bolt 608 is threadedly connected to the center of the outer wall of one side of the fixing block 606. The two sides inside the processing table 1 are provided with sliding grooves 401. The side of the clamping plate 407 away from the center of the processing table 1 is fixedly connected to the support block 405.

[0036] Support columns 2 are fixedly connected to the four corners of the lower end of the processing table 1. A PLC control panel 3 is fixedly connected to the middle of the outer wall of one side of the processing table 1. The four support columns 2 fixedly connected to the lower end of the processing table 1 enable the equipment to be placed stably on the ground, improving the stability during operation. The PLC control panel 3 fixedly connected to the processing table 1 allows the operator to control the operating status of the equipment. The baffle 602 slides inside the moving groove 601. Both sides of the lower end of the connecting block 604 penetrate through the moving groove 601 to the outside of the processing table 1. By allowing both sides of the lower end of the connecting block 604 to penetrate out of the processing table 1 and connect with the two second cylinders 6 05 is fixedly connected, so that the second cylinder 605 can drive the baffle 602, which is fixedly connected to the connecting block 604, to move inside the moving groove 601. The other side of the fixing bolt 608 passes through the fixing block 606 and is threadedly connected to the collection frame 607. A handle 7 is fixedly connected to the middle of the front outer wall of the collection frame 607. By letting one side of the fixing bolt 608 pass through the fixing block 606 and be threadedly connected to the collection frame 607, the collection frame 607 can be fixed when it slides into the fixing block 606. After the threaded connection between the fixing bolt 608 and the collection frame 607 is released, the collection frame 607 can be easily removed using the handle 7.

[0037] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The inner wall of the front end of the slide 401 is fixedly connected to a first cylinder 402. The output shaft of the first cylinder 402 is fixedly connected to a limiting block 403. The lower end of the support block 405 on the side away from the center of the processing table 1 is fixedly connected to a stop block 406.
