The utility model is provided with a second clamp that can be moved up and down by the first screw rod, so that the second clamp is moved downward to fit with the first clamp to fix the flexible circuit board, making the clamping and fixing process of the flexible circuit board simple and quick, thereby greatly improving the cutting efficiency of the flexible circuit board;

[0003] The existing fixing fixture adopts the clamping method of splint for positioning. Although the splint clamping is stable, it is easy to damage the flexible workpiece. If it is pressed from top to bottom, the surface of the flexible workpiece will be blocked, which is not conducive to the processing of the flexible workpiece after fixation, and it is not convenient for personnel to take it. The flexible workpiece will be in the groove after placement. Since the volume of the flexible workpiece is the same as the size of the placement groove, when the flexible workpiece is processed, it is necessary to push the workpiece to bend the workpiece, and then the personnel can grab the workpiece and lift it up, which reduces the processing efficiency of the flexible workpiece. In order to solve the above-mentioned problems, we propose a chip resistor oblique flexible leveling fixture. Utility Model Content

[0004] The utility model aims to provide a chip resistor oblique flexible leveling fixture, which solves the problems that the existing fixed fixture has a poor positioning effect on the flexible workpiece and is inconvenient to take the workpiece out of the groove.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a chip resistor oblique flexible leveling fixture, comprising a substrate, the bottom of the substrate is welded with a bottom plate through a supporting rod, the top and one side of the substrate are respectively provided with a placement groove and a groove, the interior of the groove is provided with two circular grooves, the interior of the placement groove is provided with a through hole connected to the circular groove, a fixing plate is installed inside the groove, one side of the fixing plate is threadedly connected with an air valve sliding switch, a vacuum pump is installed on the top of the bottom plate, a connecting pipe is fixedly sleeved between the other end of the air valve sliding switch and the vacuum pump, a threaded rod is rotatably connected to the top of the bottom plate through a bearing, a motor is fixedly sleeved on the other end of the threaded rod, a lifting plate is threadedly connected to the surface of the motor, two top plates are placed inside the placement groove through a slot, and a connecting rod is welded between the bottom of the top plate and the lifting plate.

[0006] The above technical solution can achieve a good fixing effect, which not only ensures the stability of the flexible workpiece during processing, but also avoids damage to the workpiece, with high safety. At the same time, it is easy to take the flexible workpiece out of the groove, the operation is simple and convenient, and the work efficiency of personnel is improved, with high practicality.

[0007] The utility model is further configured as follows: the base plate and the bottom plate are both made of aluminum alloy.

[0008] By adopting the above technical solution, the substrate and the bottom plate have the characteristics of light weight, high toughness and high durability.

[0009] The utility model is further configured as follows: the connecting pipe is made of PP material.

[0010] By adopting the above technical solution, the connecting pipe has the characteristics of good heat resistance, high chemical stability and high strength.

[0011] The utility model is further configured as follows: four mounting holes are opened on the top of the bottom plate.

[0012] By adopting the above technical solution, through the provision of the mounting holes, it is convenient for personnel to fix the base plate with screws, thus reducing the trouble of temporary drilling.

[0013] The utility model is further configured as follows: the threaded rod is made of stainless steel.

[0014] By adopting the above technical solution, the threaded rod has the characteristics of high strength, low density and excellent corrosion resistance.

[0015] The utility model is further configured as follows: a wear-resistant pad is bolted to the bottom of the base plate.

[0016] By adopting the above technical solution and providing the wear-resistant pad, the wear-resistant effect of the bottom of the substrate can be improved.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. The utility model first picks up the flexible workpiece and puts it into the placement groove. After the flexible workpiece is put in, the vacuum pump is started and the air valve sliding switch is turned on. After the vacuum pump is started, suction will be generated. After the suction is formed, it will pass through the connecting pipe, the groove, the circular groove and the through hole, so that the flexible workpiece in the placement groove is fixed and leveled, which can achieve a good fixing effect, not only ensuring the stability of the flexible workpiece during processing, but also avoiding damage to the workpiece, and having high safety;

[0019] 2. The utility model closes the air valve sliding switch and starts the motor after the flexible workpiece is processed. After starting, the motor will drive the threaded rod to rotate. When the threaded rod rotates, it will drive the lifting plate to move upward with the cooperation of the connecting rod. When the connecting rod moves upward, it will drive the top plate to push the workpiece out of the placement groove, which can facilitate the flexible workpiece to be taken out of the groove. The operation is simple and convenient, which improves the work efficiency of the personnel and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
