Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal production and processing, in particular to a metal cutting fixing device. Background Art
[0002] In a traditional metal cutting fixing device, clamping plates are usually located on both sides of the top of a base, and a metal workpiece is fixed at the center of the top of the base. At the same time, the clamping plates are usually designed in a square or arc shape and are directly connected to a telescopic mechanism, so that the clamping plates cannot be replaced. Since different metal workpieces have different shapes and sizes, the clamping plates cannot be replaced according to different metal workpieces, thus the stability of the metal workpiece during cutting cannot be ensured.To solve the above problems, in some metal cutting fixing devices, a connecting piece is added between the telescopic mechanism and the metal workpiece and is connected by bolts, so that the clamping plates can be replaced according to the situation of the metal workpiece to be cut, ensuring the stability of the metal workpiece during cutting. However, in this way, when using bolts for connection, since vibrations will be generated during the cutting of the metal workpiece, the vibrations will be transmitted to the bolts through the clamping plates, and the threaded connection structure of the bolts will be loosened or even broken. At the same time, bolts are usually used in multiple groups, which not only cannot ensure the connection stability but also is not convenient for disassembly and assembly operations. For this reason, a metal cutting fixing device is proposed. Content of the Utility Model
[0003] Aiming at the deficiencies of the prior art, the utility model provides a metal cutting fixing device to solve the technical problems that the connection stability cannot be ensured and the disassembly and assembly operations are not convenient.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A metal cutting fixing device, comprising:
[0005] A workbench, and side clamping plates arranged at the centers of both sides of the top of the workbench, and the bottom of the side clamping plates is in contact with the top of the workbench;
[0006] A rear connecting cylinder, arranged at the center of the outer side of the side clamping plate, and a limiting groove is opened at the top of the rear connecting cylinder;
[0007] The front connecting cylinder is arranged at the outer center of the rear connecting cylinder. A limiting post is installed at the top of the front connecting cylinder and corresponds to the limiting groove. A compression spring is horizontally installed at the center of the inner cavity of the front connecting cylinder, and a hydraulic rod is connected to the outer center of the front connecting cylinder. After placing the metal workpiece at the top center of the workbench first, the telescopic end of the hydraulic rod drives the side clamping plate to clamp and fix the metal workpiece through the front connecting cylinder and the rear connecting cylinder. When the rear connecting cylinder is connected to the front connecting cylinder, first insert the rear connecting cylinder onto the front connecting cylinder and then rotate it so that the limiting post fits against the inner wall of the limiting groove. The compression spring drives the rear connecting cylinder to move outward on the front connecting cylinder, making the limiting post fit tightly with the limiting groove. On the one hand, it not only ensures the stability of the connection between the side clamping plate and the rear connecting cylinder and the front connecting cylinder, but also facilitates disassembly and assembly operations according to different situations. On the other hand, the positions of the metal workpiece on the top of the workbench can be adjusted by two groups of non-interfering hydraulic rods through the side clamping plate, so that other parts of the metal workpiece can be machined.
[0008] Preferably, positioning side plates are horizontally installed around the outer surface of the hydraulic rod, and a first driven wheel is additionally provided at the center of the outer surface of the hydraulic rod and is connected to the positioning side plates. The first driven wheel can drive the hydraulic rod to rotate through the positioning side plates and adjust the rotation of the hydraulic rod, so as to adjust the machining surface of the metal workpiece.
[0009] Preferably, a first driving wheel meshes with the bottom of the first driven wheel, and a rotating seat is rotatably connected to the outside of the first driving wheel. The rotating seat is rotatably connected to the hydraulic rod. The first driving wheel rotates on the rotating seat, and the first driving wheel drives the first driven wheel to rotate in the same direction. The rotating seat can support the hydraulic rod and does not affect the rotation of the hydraulic rod on the rotating seat at the same time.
[0010] Preferably, a first driving motor is installed at the outer center of the rotating seat and is coaxially connected to the first driving wheel, and telescopic electric rods are installed on the front and back of the rotating seat. The first driving motor drives the first driving wheel to rotate on the rotating seat and adjusts the rotation direction of the first driving wheel, while the telescopic electric rod can drive the rotating seat to perform lifting adjustment, so that the metal workpiece rises on the top of the workbench, avoiding collision with the workbench when the metal workpiece rotates and causing damage.
[0011] Preferably, connecting columns are vertically added to the front and rear ends at the center positions on both sides of the bottom of the workbench, and the connecting columns are connected to the telescopic electric rods. The telescopic electric rod is connected to the workbench through the connecting column, thus ensuring the stability of the telescopic electric rod and its connection structure.
[0012] Preferably, a rotating table is rotatably connected to the center of the top of the workbench, and a second driven wheel is installed at the center of the bottom of the rotating table. A second driving wheel is meshed with the outside of the second driven wheel, and a second driving motor is coaxially connected to the bottom of the second driving wheel. After placing the metal workpiece on the top of the rotating table, the second driving motor drives the second driving wheel, the second driving wheel drives the second driven wheel, and then the second driven wheel drives the rotating table and the metal workpiece to rotate, so as to adjust the contact surface between the metal workpiece and the side clamping plate.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] For this metal cutting fixing device, after placing the metal workpiece at the center of the top of the workbench first, the telescopic end of the hydraulic rod drives the side clamping plate to clamp and fix the metal workpiece through the front connecting cylinder and the rear connecting cylinder. The positions of the metal workpiece on the top of the workbench can be adjusted by the side clamping plate through two groups of hydraulic rods that do not interfere with each other, so as to perform cutting processing on other parts of the metal workpiece. When connecting the rear connecting cylinder and the front connecting cylinder, first insert the rear connecting cylinder on the front connecting cylinder and then rotate it, so that the limiting column fits with the inner wall of the limiting groove, and the extrusion spring drives the rear connecting cylinder to move outward on the front connecting cylinder, making the limiting column and the limiting groove fit tightly. This not only ensures the stability of the connection between the side clamping plate and the rear connecting cylinder and the front connecting cylinder, but also facilitates disassembly and assembly operations according to different situations.
