Description

Technical Field

[0001] The utility model relates to the technical field of metal structure part manufacturing, and more specifically, relates to a burr removing device for manufacturing metal structure parts. Background Technique

[0002] Metal structure parts are widely used in steel structure parts. Metal structure parts made by welding, rolling, etc., such as aluminum alloy doors and windows, etc., need to be polished on the outside after production to remove the burrs on the outer wall of the metal structure parts to make their surfaces smooth. Metal structure parts have various shapes. As one of them, circular metal structure parts are generally formed by cutting steel plates during production. Therefore, the burrs of circular metal structure parts often appear on their edges. During the production process, deburring processing needs to be carried out on the edges of circular metal structure parts.

[0003] When the existing burr removing device for manufacturing metal structure parts removes the burrs on the edges of circular metal structure parts, it requires workers to hold the circular metal structure parts and make their edges closely adhere to the burr removing device, and continuously rotate the circular metal structure parts to switch the burr removing surface, which is rather inconvenient. And when the force of the circular metal structure parts contacting the burr removing device is not well controlled, it is easy to cause excessive grinding of the circular metal structure parts and damage to the circular metal structure parts. In view of this, we propose a burr removing device for manufacturing metal structure parts. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a burr removing device for manufacturing metal structure parts, so as to solve the technical problems that the existing burr removing device for manufacturing metal structure parts is rather inconvenient to remove the burrs on the edges of circular metal structure parts and is easy to cause damage to the circular metal structure parts.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A burr removing device for manufacturing metal structure parts, including a workbench, an installation mechanism is provided on the workbench, and a grinding mechanism is provided on one side of the installation mechanism;

[0006] The installation mechanism includes a motor A, a C-shaped support frame, and an electric telescopic rod. The motor A penetrates through the workbench surface. Both ends of the bottom of the C-shaped support frame are fixedly connected to both ends of the workbench surface. The electric telescopic rod penetrates through the top of the C-shaped support frame. The output end of the electric telescopic rod extends to the middle of the C-shaped support frame and is fixedly connected to a pressing plate A. The output end of the motor A is fixedly connected to a long shaft, and a pressing plate B is fixedly connected to the top of the long shaft. An installation cavity is formed on the opposite side of the pressing plate B and the pressing plate A;

[0007] The grinding mechanism includes a motor B and a mounting frame. The motor B is arranged on one side of the top of the C-shaped support frame. The output end of the motor B is fixedly connected with a grinding rod. One outer wall of the mounting frame is fixedly connected with the surface of one side of the top of the C-shaped support frame. The top of the motor B is fixedly connected with a mounting block. Both sides of the mounting block are slidably connected with the inner walls of both sides of the mounting frame. A screw rod is arranged in the mounting block. Both ends of the screw rod are rotatably connected with the inner walls of both ends of the mounting block. One end of the screw rod is fixedly connected with a handwheel through a short shaft.

[0008] Preferably, the pressure plate B and the pressure plate A are on the same axis line, and a positioning mechanism is arranged at the bottom of the pressure plate B.

[0009] Preferably, the positioning mechanism includes a mounting plate. The middle of the mounting plate is movably sleeved on the surface of the long shaft. Both ends of the mounting plate are slidably connected with the inner walls of both ends of the C-shaped support frame. Both ends of the mounting plate are symmetrically provided with mounts. A guide rod is fixedly connected in the mount. A slider is sleeved on the surface of the guide rod. A spring is sleeved on the surface of the guide rod. One end of the spring is fixedly connected with one side surface of the slider. The other end of the spring is fixedly connected with the inner wall of the mount close to one end of the mounting plate head. The top of the slider is fixedly connected with a pressing block.

[0010] Preferably, both opposite surfaces of the two pressing blocks are arc-shaped concave towards the opposite surfaces of the two pressing blocks.

[0011] Preferably, sliders are arranged at both ends of the mounting plate. Sliding grooves extending to the bottoms of both ends of the C-shaped support frame are opened on the inner walls of both ends of the C-shaped support frame. The sliders and the sliding grooves are limited and slid in the vertical direction.

[0012] Preferably, a through hole is opened on the top of the C-shaped support frame. The electric telescopic rod passes through the through hole, and a limiting ring is fixedly sleeved on the surface of the electric telescopic rod along the position of the through hole. A limiting groove adapted to the limiting ring is opened on the C-shaped support frame at the position relative to the limiting ring.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. Through the installation mechanism and the grinding mechanism, when the electric telescopic rod extends, it drives the pressure plate A to move downward to clamp and fix the circular metal structure between the pressure plates A. The motor A drives the circular metal structure clamped and fixed by the pressure plates A and B to rotate through the long shaft. The motor B drives the grinding rod to rotate. By turning the handwheel to rotate the screw rod, the mounting block is driven to slide in the mounting frame, and then the motor B is driven to move. The position of the grinding rod can be adjusted according to the diameter of the circular metal structure, so that the grinding rod fits the edge of the circular metal structure, and the edge of the rotating circular metal structure is ground, which is more simple and convenient. At the same time, it reduces the phenomenon that the circular metal structure is damaged due to excessive grinding caused by the failure to control the force when the circular metal structure is connected to the burr removal device properly.

[0015] 2. The present utility model also designs a positioning mechanism. The reaction force of the spring drives the two pressure blocks to move towards each other, thereby positioning the circular metal structure on the pressure plate B, making the center of the circular metal structure and the center of the pressure plate B on the same axis line, and enabling the circular metal structure and the pressure plate B to rotate on the same axis line. It is more convenient for the quick installation of the circular metal structure and ensures that the side of the circular metal structure can be connected to the grinding rod during rotation.

A limit groove 2023 adapted to the limit ring 2031 is opened at the position of the C-shaped support frame 202 relative to the limit ring 2031. When the motor A 201 drives the circular metal structural part clamped and fixed by the pressure plate A 204 and the pressure plate B 206 to rotate, it drives the electric telescopic rod 203 to rotate in the through hole 2022 and drives the limit ring 2031 to rotate in the limit groove 2023.
