[0002] Generally, parts produced by casting are ordinary workpieces, which need to be measured and polished to make them precision workpieces. Precision plates mostly refer to metal plates made by forging, rolling or casting.

[0003] For example, the patent with publication number CN216298627U discloses a precision clamping and fixing device for precision plates, including a fixing assembly, which includes an operating box, a fixed rod, a moving rod, a moving plate, a motor, a screw, a tilting rod, an L-shaped rod, and a clamp. The motor drives the screw to rotate, and under the action of the threaded hole, the screw drives the moving plate to move upward, and the moving plate drives the moving rod to slide on the fixed rod, and the moving plate drives the clamp to slide on the L-shaped rod through the tilting rod, and the clamp drives the first connecting rod to slide on the first positioning rod, and the clamp drives the corresponding protective plate to contact and fix the plate through the elastic airbag, so as to facilitate the clamping and fixing of plates of different specifications. When the protective plate is subjected to impact force, the protective plate squeezes or stretches the elastic airbag, and at the same time, the protective plate drives the second connecting rod to slide on the second positioning rod, and under the action of the elastic force of the elastic airbag and the second spring itself, it plays a buffering role to reduce damage.

[0004] At present, the existing fixing tooling adopts a fixing method of clamping the two sides of the plate when fixing the precision plate parts, which causes the precision plate parts to be warped due to vibration during the processing, thereby affecting the precision of the plate processing to a certain extent, and also affecting the efficiency of the precision plate processing. Therefore, an easy-to-use mechanical fixing device is proposed to solve the above problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0023] like Figure 1-4 As shown, the utility model provides an easy-to-use mechanical fixing device, comprising a base 1, a fixing mechanism 2 and a mounting hole 3, wherein the fixing mechanism 2 is arranged on the base 1, and the mounting hole 3 is opened at the bottom of the base 1.

[0024] The fixing mechanism 2 includes a bidirectional screw 201 and a first connecting block 202, the first connecting block 202 is threadedly connected to the bidirectional screw 201, a first fixing frame 203 is fixedly installed on the upper surface of the first connecting block 202, a cylinder 208 is fixedly installed on the first fixing frame 203, a fixing plate 210 is fixedly installed on the telescopic end of the cylinder 208, a second connecting block 209 is fixedly installed on the bottom of the first fixing frame 203, a polished rod 205 is arranged on the second connecting block 209, and a second fixing frame 204 is arranged on the base 1, and the user turns the knob 207 to drive the bidirectional screw 201 to rotate. The screw rod 201 is rotated to adjust the distance between the first fixing frame 203 and the second fixing frame 204. When the distance between the first fixing frame 203 and the second fixing frame 204 is adjusted, the cylinder 208 is started to push the fixing plate 210 downward, so that the fixing plate 210 is pressed down to the upper surface of the precision plate to limit and fix the precision plate. The downward limit method can make the precision plate be fixed more firmly, avoid the precision plate from being affected by processing vibration, and cause the precision plate to warp, thereby improving the accuracy of the processing of the precision plate.

[0025] An internal threaded hole is provided on the first connection block 202 , and the bidirectional screw 201 is threadedly connected inside the internal threaded hole. A knob 207 is fixedly installed at the front end of the bidirectional screw 201 , and the setting of the knob 207 allows the user to conveniently rotate the bidirectional screw 201 .

[0026] The bidirectional screw 201 is rotatably connected to the inside of the base 1 through a bearing, and the light rod 205 is fixedly installed inside the base 1. A sliding hole is opened on the second connecting block 209, and the light rod 205 passes through the inside of the sliding hole. The setting of the light rod 205 can play a role of limiting and guiding the second connecting block 209.

[0027] There are four mounting holes 3, which are respectively opened at the four corners of the bottom of the base 1. A guide opening 5 is opened on the upper surface of the base 1, and the first fixing frame 203 passes through the inside of the guide opening 5. The setting of the guide opening 5 can play a limiting and guiding role for the first fixing frame 203. The setting of the mounting holes 3 can facilitate the installation and fixing of the base 1 on the processing table.

[0028] A limiting hole is provided on the upper surface of the first fixing frame 203, and a limiting column 206 is inserted into the inner part of the limiting hole. The limiting column 206 is fixedly connected to the upper surface of the fixing plate 210. The setting of the limiting column 206 can play a limiting and guiding role for the fixing plate 210, so that the fixing plate 210 can move stably.

[0029] In this embodiment, the user rotates the knob 207 to drive the bidirectional screw 201 to rotate, so that the distance between the first fixing frame 203 and the second fixing frame 204 is adjusted. When the first fixing frame 203 and the second fixing frame 204 are adjusted, the cylinder 208 is started to push the fixing plate 210 to move downward, so that the fixing plate 210 is pressed down to the upper surface of the precision plate to limit and fix the precision plate. The downward limit method can make the precision plate be fixed more firmly, avoid the precision plate from being affected by processing vibration, and cause the precision plate to warp, thereby improving the accuracy of the processing of the precision plate.

The arrangement of the anti-skid pad 6 and the rubber pad 4 can facilitate the fixation of precision panels.

[0031] In this embodiment, by providing the rubber pad 4 and the anti-slip pad 6, the friction between the precision plate and the base 1 and the fixed plate 210 can be increased, so that the precision plate is fixed more firmly, further improving the practicality of the fixing tooling.

[0032] When the utility model is in use, the user rotates the knob 207 to drive the bidirectional screw 201 to rotate, so that the distance between the first fixing frame 203 and the second fixing frame 204 is adjusted. When the first fixing frame 203 and the second fixing frame 204 are adjusted, the cylinder 208 is started to push the fixing plate 210 to move downward, so that the fixing plate 210 is pressed down to the upper surface of the precision plate, and the precision plate is limited and fixed. The downward pressure limiting method can make the precision plate fixed more firmly, avoid the precision plate from being affected by processing vibration, and cause the precision plate to warp up, thereby improving the accuracy of the processing of the precision plate; by providing the rubber pad 4 and the anti-slip pad 6, the friction between the precision plate and the base 1 and the fixing plate 210 can be increased, so that the precision plate is fixed more firmly, and the practicality of the fixing tool is further improved.
