Description

Technical Field

[0001] The utility model relates to the field of positioning structures, in particular to a positioning structure for a punching device. Background Art

[0002] At present, a Chinese utility model with announcement number CN217454205U discloses a positioning structure for a secondary punching device for rubber products, which relates to the technical field of punching positioning structures, including a workbench, a detachable mounting plate fixedly connected to one side of the workbench, a fixed seat fixedly connected to the top side of the mounting plate, a rotatable drill head is driven up and down by an electric push rod to punch holes in the rubber product, and the electric push rod is driven left and right by a slider to punch holes in different positions of the rubber product, and the rubber product is positioned by placing the rubber product on top of the second clamping plate and clamping it with the first clamping plate, so that the rubber product can be accurately punched, thereby solving the problem that most of the existing opening equipment is generally manual for punching, which is relatively inefficient, and manual punching is generally not very safe, which can easily cause injuries to workers and affect production efficiency, and manual punching is generally not easy to accurately find the position where holes need to be punched, causing deviations.

[0003] Although the existing positioning structure can clamp the workpiece to prevent the workpiece from shifting during the processing of the punching device, there are still other problems in use. For example, the positioning effect is poor, which can only ensure that the workpiece cannot shift. However, in order to open the holes on the workpiece at the appropriate position, personnel need to adjust the position of the workpiece before placing each workpiece, which is time-consuming and labor-intensive, reduces the processing efficiency of the workpiece, and is not convenient for processing and collecting debris. Debris will be generated when the workpiece has holes, and the debris will accumulate on the table after formation. In order to prevent the debris from affecting the placement of the workpiece, personnel need to clean the table frequently, which increases the workload of personnel. In order to solve the above-mentioned problems, we propose a positioning structure for a punching device. Utility Model Content

[0004] The utility model aims to provide a positioning structure for a punching device, which solves the problems that the existing positioning structure has poor positioning effect and is inconvenient to collect and process debris.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a positioning structure for a punching device, comprising a fixing plate, a through groove is opened inside the fixing plate, mounting plates are welded to the front and back sides of the fixing plate, a collecting box is placed at the bottom of the fixing plate, the volume of the collecting box is the same as that of the fixing plate, a bidirectional screw is rotatably connected to the inside of the through groove through a bearing, the surface of the bidirectional screw is threadedly connected to two threaded plates, a clamping plate is welded to the top of the threaded plate, a fixing frame is symmetrically installed on the top of the fixing plate, two guide plates are arranged on the top of the fixing plate, the two ends of the guide plate extend to the inside of the two fixing frames respectively, a threaded rod is welded to the top of the guide plate, and a nut is threadedly connected to the surface of the threaded rod.

[0006] The adoption of the above technical solution can achieve good positioning effect, improve the processing efficiency of the workpiece, ensure the accuracy of the workpiece drilling position, and at the same time facilitate the collection and processing of debris. The operation is simple and convenient, which reduces the burden of personnel on cleaning the table and is highly practical.

[0007] The utility model is further configured as follows: a handle is welded on the front side of the collection box.

[0008] By adopting the above technical solution and providing a handle, it is convenient for personnel to pull the collection box outward.

[0009] The utility model is further configured as follows: two slide rails are bolted inside the through groove, and sliding blocks slidably connected to the slide rails are welded on the front and back sides of the threaded plate.

[0010] By adopting the above technical solution, the threaded plate can be limited by setting the slide rail and the slider to prevent the threaded plate from rotating during the left and right movement.

[0011] The utility model is further configured as follows: a turning handle is welded on the other end of the bidirectional screw.

[0012] By adopting the above technical solution and setting the turning handle, it is convenient for personnel to rotate the bidirectional screw.

[0013] The utility model is further configured as follows: rubber pads are installed on opposite sides of the two clamping plates.

[0014] By adopting the above technical solution, the workpiece can be protected by providing the rubber pad, so as to prevent the clamping plate from scratching the surface of the workpiece when clamping.

[0015] The utility model is further configured as follows: the threaded rod and the nut are both made of stainless steel.

[0016] By adopting the above technical solution, the threaded rod and the nut have the characteristics of high strength, low density and excellent corrosion resistance.

[0017] The utility model is further configured as follows: a mounting hole is provided on the top of the mounting plate.

[0018] By adopting the above technical solution and providing the mounting holes, it is convenient for personnel to fix the mounting plate on the table with screws.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The utility model fixes the mounting plate on the table surface with screws. After the mounting plate is fixed, the workpiece is placed on the fixing plate, and then the guide plates on the front and rear sides are pulled to fit the workpiece, and then the nuts are tightened to fix the guide plates. When the guide plates are fixed, the turning handle is held to drive the bidirectional screw to rotate. When the bidirectional screw rotates, it will drive the two threaded plates to move inward synchronously through the cooperation of the slide rail and the slider. When the threaded plate moves inward, it will drive the clamping plate to clamp the workpiece, which can achieve good positioning effect, improve the processing efficiency of the workpiece, and ensure the accuracy of the workpiece drilling position.

[0021] 2. The utility model picks up the collection box, places the collection box at the bottom of the fixed plate and pushes it inward to the bottom until the collection box overlaps with the upper fixed plate. The debris generated when the workpiece is punched will enter the collection box through the through groove. When there are too many debris, just pull out the collection box, which can facilitate the collection and treatment of the debris. The operation is simple and convenient, reduces the burden of personnel on cleaning the countertop, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
