Description

Technical Field

[0001] This utility model relates to the field of grinding tooling technology, specifically a grinding tooling for metal parts processing. Background Technology

[0002] Utility model patent CN208644968U discloses a grinding fixture for metal surface processing, including a base, a grinding box fixedly mounted on the top of the base, a protective cover fixedly mounted on the top of the grinding box, and a motor fixedly mounted inside the protective cover. This grinding fixture for metal surface processing can prevent the metal workpiece to be ground from shifting in the front-to-back direction. Twisting the adjusting rod moves it downwards within the grinding box, thereby moving the limiting axis downwards to press against the metal workpiece, restricting its vertical displacement, and thus stably fixing the workpiece. This prevents uneven grinding thickness. The metal workpiece is ground while moving on a platform, improving grinding efficiency and effect while reducing manual labor.

[0003] However, when using this device, the clamping stability of the metal parts is not enough. Also, the device is not convenient for clamping metal parts with different edge shapes. Utility Model Content

[0004] The purpose of this utility model is to provide a grinding fixture for metal parts processing, which solves the problems of insufficient stability in clamping the edge of metal parts and the inconvenience of clamping metal parts with different edge shapes when using the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding fixture for processing metal parts, comprising a base, a fixing lug fixedly connected to the edge of the base, a sliding plate slidably connected to the inner side of the base, a clamping mechanism provided on the sliding plate, a bidirectional screw threadedly connected to the inside of the sliding plate, a support plate fixedly connected to the inside of the base, the support plate and the bidirectional screw being rotatably connected, and a knob fixedly connected to the middle of the outer side of the bidirectional screw.

[0006] Preferably, a turntable is fixedly connected to the end of the bidirectional screw, and the turntable contacts the support plate. The rotation of the bidirectional screw is controlled by the turntable.

[0007] Preferably, a limiting plate is fixedly connected to the top inner side of the base, and the limiting plate is slidably connected to the knob. The limiting plate limits the movement of the knob.

[0008] Preferably, the clamping mechanism includes a square tube. The upper end of the slide plate is fixedly connected to the square tube. A slide rod is slidably connected inside the square tube. A slide block is fixedly connected to the upper end of the slide rod. A mounting seat is slidably connected inside the slide block. A screw is mounted inside the mounting seat via a bearing. The screw and the slide block are threaded together. A clamping block is rotatably connected inside the mounting seat. Multiple evenly distributed top blocks are fixedly connected to the end of the clamping block. By rotating the screw and the slide block to perform threaded movement, the mounting seat slides relative to the slide block. This allows the position of each clamping block relative to the slide block to be adjusted, enabling the device to clamp metal parts with different edge shapes, thus increasing the device's applicability.

[0009] Preferably, the base has an internal groove that is slidably connected to the square tube. The groove guides the movement of the square tube.

[0010] Preferably, a slider is fixedly connected to the lower end of the slide block, and the slider is slidably connected to the base. The slider provides auxiliary support to the slide block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses the rotation of the bidirectional screw and the slide plate to make a threaded motion, which allows the slide plate to drive multiple clamping mechanisms to move simultaneously to clamp the metal parts at multiple points. This enables the device to stably clamp the metal parts. In use, the slide rod and the square tube can be detached and the slide base can be disassembled, which is convenient for clamping metal parts with more complex contours.

[0013] 2. This utility model uses the rotation of the screw and the slide to make a threaded movement, which causes the mounting base to slide relative to the slide. This allows the position of each clamping block relative to the slide to be adjusted, thus enabling the device to clamp metal parts with different edge shapes, making the device more versatile.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-2 A grinding fixture for processing metal parts includes a base 1, a fixing lug 2 fixedly connected to the edge of the base 1, a sliding plate 3 slidably connected to the inner side of the base 1, a clamping mechanism 4 provided on the sliding plate 3, a double-ended screw 5 threadedly connected inside the sliding plate 3, a support plate 6 fixedly connected inside the base 1, the support plate 6 and the double-ended screw 5 rotatably connected, a turntable 7 fixedly connected to the end of the double-ended screw 5, the turntable 7 contacting the support plate 6, the rotation of the double-ended screw 5 controlled by the turntable 7, a knob 8 fixedly connected to the middle of the outer side of the double-ended screw 5, a limiting plate 9 fixedly connected to the top inner side of the base 1, the limiting plate 9 and the knob 8 slidably connected, the knob 8 limited by the limiting plate 9.

[0021] Please see Figures 1-4 The clamping mechanism 4 includes a square tube 41. The upper end of the slide plate 3 is fixedly connected to the square tube 41. The base 1 has a sliding groove 49 inside, which is slidably connected to the square tube 41. The sliding groove 49 guides the movement of the square tube 41. A slide rod 42 is slidably connected inside the square tube 41. A slide block 43 is fixedly connected to the upper end of the slide rod 42. A slider 44 is fixedly connected to the lower end of the slide block 43. The slider 44 is slidably connected to the base 1. The slider 44 provides auxiliary support for the slide block 43. A mounting bracket is slidably connected inside the slide block 43. The mounting base 45 has a screw 46 mounted inside via bearings. The screw 46 and the slide 43 are connected by threads. A clamping block 47 is rotatably connected inside the mounting base 45. Multiple evenly distributed top blocks 48 are fixedly connected to the end of the clamping block 47. By rotating the screw 46 and the slide 43 to make threaded movement, the mounting base 45 slides relative to the slide 43. This allows the position of each clamping block 47 relative to the slide 43 to be adjusted, enabling the device to clamp metal parts with different edge shapes and making the device more versatile.

[0022] The specific implementation process of this utility model is as follows: In use, the metal part is placed on the base 1, and the turntable 7 is manually rotated. The turntable 7 drives the bidirectional screw 5 to rotate, and the rotation of the bidirectional screw 5 and the sliding plate 3 make a threaded movement, which in turn causes the sliding plate 3 to drive the square cylinder 41 to move. The square cylinder 41 drives the sliding rod 42 to move, the sliding rod 42 drives the sliding seat 43 to move, the sliding seat 43 drives the mounting base 45 to move, and the mounting base 45 drives the clamping block 47 to move. The movement of the clamping block 47 causes the top block 48 to contact the metal part. By rotating the bidirectional screw 5 and the sliding plate 3 to make a threaded movement, the sliding plate 3 can drive multiple clamping mechanisms 4 to move together. The device uses multiple points to clamp the metal parts, enabling stable clamping. When the metal parts have complex contours, the slide bar 42 and square tube 41 can be detached, and the slide block 43 can be disassembled to facilitate clamping metal parts with complex contours. Then, the screw 46 is rotated, and the screw 46 rotates and the slide block 43 makes a threaded movement, which causes the mounting base 45 to slide relative to the slide block 43. This allows the position of each clamping block 47 relative to the slide block 43 to be adjusted, enabling the device to clamp metal parts with different edge shapes, thus making the device more versatile.
