Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a fixed mechanical fixture for machining. Background Technology

[0002] The machining process refers to the process of changing the shape, size, relative position and properties of a workpiece to make it a qualified part by using machining methods. When machining a workpiece, it is necessary to clamp the workpiece to ensure its stability.

[0003] For example, Chinese patent application CN202122486475.4 discloses a fixed mechanical clamp for machining, which specifically includes a clamp body, a fastening mechanism, and a support plate. A driven gear is provided at the upper end of the driving gear, cooperating with the driving gear. A bidirectional screw is fixedly connected to the middle of the driven gear and rotatably connected to the inside of the clamp body. Movable plates are provided at both ends of the bidirectional screw, internally threaded to the surface of the bidirectional screw. A fixed clamping plate is fixedly connected to the upper end of the movable plates. A limiting through groove is formed on the upper surface of the clamp body, slidingly connected to the surface of the movable plates. However, it also has the following technical problems:

[0004] In actual workpiece processing, the waste generated during processing will enter the fixture body through the limiting groove. The waste is easy to adhere to the screw groove of the bidirectional screw, causing the moving plate to be obstructed on the bidirectional screw. It can be seen that the above structure makes it difficult for the fixed clamping plate to hold the workpiece. Utility Model Content

[0005] To address the problem mentioned in the background section that the existing technology makes it difficult for the fixed clamping plate to hold the workpiece, this utility model provides the following technical solution:

[0006] A fixed mechanical fixture for machining, comprising a clamping structure;

[0007] The clamping structure includes an inner frame and an outer frame for collecting waste chips, and clamping blocks for clamping workpieces are installed on the inner sides of the inner frame and the outer frame.

[0008] The lower end of the clamping structure is equipped with a support structure for limiting the clamping structure. The support structure includes two symmetrically arranged moving components, which are used to support and limit the inner frame and the outer frame. The lower end of the moving components is equipped with a bidirectional lead screw for cooperating with the moving components to control the inner frame and the outer frame to move in opposite directions.

[0009] Furthermore, the support structure includes a support platform, the middle of which is machined with a groove for sliding of the moving component, and a bidirectional lead screw is installed in the middle of the groove cavity. A motor for controlling the rotation of the bidirectional lead screw is installed at the right end of the bidirectional lead screw, and mounting seats are installed at both the front and rear ends of the support platform.

[0010] Furthermore, the moving component includes an L-shaped moving plate, with two limiting grooves machined in the middle of the L-shaped moving plate. A reinforcing rib for increasing the mechanical strength of the L-shaped moving plate is installed on one side of the L-shaped moving plate. A connecting groove is opened on the side of the reinforcing rib near the L-shaped moving plate. A fixing block is installed on one side of the L-shaped moving plate, and a magnetic block is installed inside the fixing block.

[0011] Furthermore, a screw nut is installed on the lower end of one side of the L-shaped moving plate to cooperate with the bidirectional screw to control the L-shaped moving plate to move left and right. The moving assembly includes a pull rod for locking the inner frame and the outer frame, and the pull rod is inserted into the connecting groove. A magnetic block two for magnetic attraction with magnetic block one is installed on the end of the pull rod near the fixed block.

[0012] Furthermore, positioning blocks are installed on the outer sides of both the inner and outer frames, and the positioning blocks are inserted into the limiting grooves. The center of the positioning block is provided with a hole for inserting the pull rod. Magnetic strips for magnetic attraction of the inner frame are installed on the outer sidewall and the outer bottom wall of the outer frame.

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

[0014] This utility model, through the setting of the clamping structure, allows the clamping blocks on the inner and outer frames to clamp the workpiece after the workpiece is clamped. The inner and outer frames can also collect the waste generated during processing, preventing the waste from scattering everywhere and causing the outer or inner frame to be unable to move. This avoids the situation where the clamping blocks cannot clamp the workpiece. The magnetic attraction between magnetic block two and magnetic block one allows the pull rod to quickly assemble and disassemble the inner or outer frame, so as to facilitate the cleaning of waste inside the inner and outer frames.

[0025] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0026] Please see Figures 1-5 This utility model provides a fixed mechanical fixture for machining, including a clamping structure 002. The clamping structure 002 includes an inner frame 300 and an outer frame 400 for collecting waste chips. Clamping blocks 10 for clamping workpieces are fixedly installed on the inner sides of the inner frame 300 and the outer frame 400. By adjusting the distance between the inner frame 300 and the outer frame 400, workpieces of different sizes can be clamped, so that the workpiece remains stable during machining.

[0027] The lower end of the clamping structure 002 is equipped with a support structure 001 for limiting the clamping structure 002. The support structure 001 includes two symmetrically arranged moving components 200, which are used to support and limit the inner frame 300 and the outer frame 400. The lower end of the moving component 200 is equipped with a bidirectional lead screw 120 for cooperating with the moving component 200 to control the inner frame 300 and the outer frame 400 to move in opposite directions. The spiral grooves on the left and right sides of the bidirectional lead screw 120 rotate in opposite directions, so that when the moving components 200 on the left and right sides of the bidirectional lead screw 120 move, the two moving components 200 move in opposite directions, thereby adjusting the distance between the inner frame 300 and the outer frame 400.

[0028] The support structure 001 includes a support platform 100. A groove 110 is machined in the middle of the support platform 100 for sliding of the movable component 200. A bidirectional lead screw 120 is installed in the middle of the groove 110. A motor 121 for controlling the rotation of the bidirectional lead screw 120 is installed at the right end of the motor 120. The bidirectional lead screw 120 is installed at the output end of the motor 121, so that after the motor 121 starts, the bidirectional lead screw 120 rotates, synchronously driving the inner frame 300 and the outer frame 400 to move in opposite directions. Mounting seats 130 are fixedly installed at both the front and rear ends of the support platform 100. The support platform 100 can be fixed to the machining table by bolts passing through the central holes of the mounting seats 130.

[0029] The moving component 200 includes an L-shaped moving plate 210. Two limiting grooves 211 are machined in the middle of the L-shaped moving plate 210. A reinforcing rib 212 for increasing the mechanical strength of the L-shaped moving plate 210 is fixedly installed on one side of the L-shaped moving plate 210. A connecting groove 213 is opened on the side of the reinforcing rib 212 near the L-shaped moving plate 210. A fixing block 214 is fixedly installed on one side of the L-shaped moving plate 210. A magnetic block 215 is installed inside the fixing block 214.

[0030] A screw nut 220 is installed on the lower side of one side of the L-shaped moving plate 210 to cooperate with the bidirectional screw 120 to control the L-shaped moving plate 210 to move left and right. The screw nut 220 is fixedly installed on the lower side of one side of the L-shaped moving plate 210 by bolts, so that when the screw nut 220 moves, it drives the L-shaped moving plate 210 to move synchronously. The movable component 200 includes a pull rod 230 for locking the inner frame 300 and the outer frame 400. The pull rod 230 is inserted into the connecting groove 213. The pull rod 230 is an L-shaped rod body, including a long rod and a short rod. The short rod of the pull rod 230 has a through hole in the middle to facilitate pulling the pull rod 230. A magnetic block 231 for magnetic attraction with magnetic block 215 is installed at one end of the pull rod 230 near the fixing block 214. When one end of the pull rod 230 abuts against one side of the fixing block 214, magnetic block 231 and magnetic block 215 are magnetically attracted, so that the position of the pull rod 230 is fixed, thereby fixing the inner frame 300 or the outer frame 400.

[0031] Positioning blocks 20 are fixedly installed on the outer sides of both the inner frame 300 and the outer frame 400. Two positioning blocks 20 are provided, each inserted into a limiting groove 211. A insertion hole 21 for inserting a pull rod 230 is provided in the center of each positioning block 20. The insertion hole 21 and the cavity of the connecting groove 213 are the same size. After the positioning block 20 is inserted into the limiting groove 211, the insertion hole 21 and the connecting groove 213 are aligned, and one side of the inner frame 300 or the outer frame 400 is in close contact with the groove. On one side of the L-shaped movable plate 210, after the pull rod 230 passes through the connecting groove 213 and the insertion hole 21, one side of the pull rod 230 abuts against the fixing block 214, causing the first magnetic block 215 and the second magnetic block 231 to be magnetically attracted together, thereby fixing the position of the inner frame 300 or the outer frame 400. The pull rod 230 allows for quick disassembly of the inner frame 300 and the outer frame 400, facilitating the cleaning of debris inside them. Magnetic strips 410 for magnetic attraction of the inner frame 300 are installed on both the outer sidewall and the outer bottom wall of the outer frame 400. The inner frame 300 is made of magnetically attractable steel, ensuring that the outer wall of the inner frame 300 is always in close contact with the inner wall of the outer frame 400.

[0032] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
