It can be widely used in cutting, punching, blanking, bending, riveting and forming processes. It processes the metal into parts by applying strong pressure to the metal blank to cause plastic deformation and fracture.

[0003] When existing presses are used, they mostly position workpieces. However, during the stamping process, the impact force is relatively large, and the mechanism for fixing the workpiece lacks corresponding buffering and is subjected to long-term vibration, resulting in severe wear and tear and reducing the service life.

However, the clamping surface of the positioning mechanism is prone to wear after long-term use. At the same time, if dust and impurities adhere to the positioning clamping surface, the clamped workpiece will be scratched, which has certain limitations. Utility Model Content

[0005] The purpose of the utility model is to provide a workbench positioning device for a press machine to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A workbench positioning device for a press machine comprises a workbench body and a controller; a controller is slidably mounted on one end of the workbench body, a fixing frame is fixedly connected to the top of the workbench body, a connecting plate is fixedly mounted on the top of the fixing frame, a positioning plate is arranged on the inner side of the fixing frame, a maintenance component is arranged on the inner side of the positioning plate, the maintenance component is used to clean and maintain the surface of the positioning plate, a protective component is arranged on the periphery of the maintenance component, the protective component is used to shield and protect the periphery of the positioning plate.

[0008] The above-mentioned technical scheme is adopted. In this scheme, by adjusting the positioning plate, workpieces of different lengths can be clamped and positioned from both sides, so as to facilitate processing of the workpieces. After the positioning plate is retracted to fit with the inner side of the fixed frame, the surface of the inner side of the positioning plate can be lubricated and cleaned by installing maintenance components, so that the lubricant is evenly applied to the surface of the positioning plate, and the dust and impurities on the surface of the positioning plate can be cleaned, so as to facilitate subsequent clamping and positioning of the workpiece. By installing protective components, the periphery of the positioning plate can be shielded, thereby protecting the positioning plate and achieving the effect of dustproof protection.

[0009] A further improvement of the technical solution of the utility model is that the maintenance component includes an electric push rod, which is fixedly connected to the top of the connecting plate, and the electric push rod passes through the bottom of the connecting plate and is fixedly installed with an adjustment frame, and a plurality of extrusion heads are fixedly connected to the outside of the adjustment frame, and a brush is fixedly installed on the outside of the adjustment frame, and the brush is located at the top and bottom of the extrusion head, and the brush is in contact with the inner side of the positioning plate, and a connecting pipe is fixedly installed on the top of the adjusting frame.

[0010] The above-mentioned technical scheme is adopted. In this scheme, after the positioning plate is moved to fit with the inner side of the fixed frame, the electric push rod is installed to drive the adjusting frame to move downward, and at the same time drive the brush to move downward along the inner surface of the positioning plate to clean the surface of the positioning plate, thereby clearing away dust and impurities on the surface of the positioning plate, avoiding the adhesion of dust and impurities on the surface of the positioning plate and affecting the subsequent clamping and positioning effect of the workpiece. In the process of the adjusting frame moving downward, the connecting pipe is installed to connect the adjusting frame and the external lubricant supply structure, so that the lubricant can be discharged through the extruder head, thereby lubricating and maintaining the surface of the positioning plate, thereby extending the service life of the positioning plate.

[0012] The above-mentioned technical scheme is adopted. In this scheme, after the adjustment frame moves downward, the two ends and the inner side of the positioning plate can be covered by installing a protective cover. At the same time, by setting the bottom plate to a special shape, during the downward movement of the protective cover, the positioning plate first contacts the bottom of the bottom plate, and the positioning plate can squeeze the bottom plate inward. After the bottom plate is moved to the bottom, the elastic force of the spring itself can be used to squeeze the bottom plate outward, so that it moves to the bottom of the positioning plate, thereby covering the positioning plate from the bottom, thereby achieving a dust-proof protection effect on the positioning plate.

[0013] A further improvement of the technical solution of the utility model is that a plurality of limit blocks are fixedly installed on the bottom of the adjustment frame, and each limit block is slidably connected to the inside of the bottom plate.

[0014] The above technical solution is adopted. In this solution, the base plate and the adjustment frame can be connected by installing a limit block, thereby ensuring that the base plate and the protective cover can move synchronously with the adjustment frame. At the same time, the limit block can be used to guide and limit the sliding trajectory of the base plate at the bottom of the adjustment frame.

[0015] A further improvement of the technical solution of the utility model is that the peripheries of the top and bottom of the bottom plate are respectively provided with inclined surfaces inclined toward the bottom and the bottom.

[0016] The above technical solution is adopted. In this solution, by setting the bottom plate into a special shape, when the protective cover moves upward or downward, the positioning plate can automatically squeeze the bottom plate inward without manual operation, thereby avoiding affecting the movement of the protective cover.

[0017] A further improvement of the technical solution of the utility model is that a slider is fixedly installed on the bottom of the fixed frame, a slide groove matching the shape of the slider is opened inside the workbench body, plugs are inserted at both ends of the workbench body, and the plugs are embedded in the inside of the slider, and a plurality of through holes are opened at both ends of the workbench body, each through hole is horizontally distributed, and each through hole is located on the outside of the controller.

[0018] The above-mentioned technical solution is adopted. In this solution, the fixed frame and the workbench body can be connected by installing a slider. By sliding the slider inside the slide groove in the workbench body, the fixed frame can be driven to move, so that the positioning plate can be quickly moved, the positioning plate is moved to a rough position close to the workpiece, and then the position of the slider inside the workbench body is limited by a bolt.

[0019] A further improvement of the technical solution of the utility model is that a screw is rotatably installed on the outer side of the positioning plate through a bearing, the screw passes through the interior of the fixing frame and is threadedly connected to the fixing frame, and a limiting rod is fixedly installed on the outer side of the positioning plate at both ends of the screw, the limiting rod passes through the interior of the fixing frame and is slidably connected to the fixing frame.

[0020] The above-mentioned technical solution is adopted. In this solution, by rotating the screw, the positioning plate can be driven to move inward, thereby achieving precise movement of the positioning plate, so that the positioning plate can clamp and position the workpiece. By installing a limit rod, the sliding trajectory of the positioning plate can be guided and limited, thereby preventing the positioning plate from rotating synchronously with the screw.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
