[0002] In the mechanical manufacturing process, fixtures are often used to fix the processing object so that it occupies the correct position for construction or inspection. The non-Newtonian fluid phase change fixture is a special fixture that uses the characteristics of non-Newtonian fluid to achieve workpiece clamping.
[0003] When using traditional non-Newtonian fluid phase change clamps to clamp some workpieces with lower hardness, the workpieces are very likely to deform during the processing. Once deformation occurs, a gap will be generated between the outer wall of the workpiece and the outer wall of the clamp, which will cause the clamp to be unable to clamp the workpiece well, thereby affecting the clamping effect of the workpiece.

[0006] As a preferred technical solution of the utility model: one end of the rotating plate away from the fixed plate is rotatably connected to the outer wall of the pull rod, there are two fixed plates, and the two fixed plates are respectively installed on the top of the base.
[0007] As a preferred technical solution of the utility model: the fixed plate, the rotating plate and the L-shaped plate are all made of high-carbon steel, and a silicone cushion is installed on the outer edge of the telescopic rod away from the trachea.

[0009] As a preferred technical solution of the utility model: the inner cavity of the trachea is communicated with the inner cavity of the connecting pipe, and the inner cavity of the connecting pipe is respectively connected to the tracheas on the top of multiple fixing blocks.
[0010] As a preferred technical solution of the utility model: the end of the transmission tube away from the connecting tube is connected to the air outlet of the micro air pump, the outer wall of the L-shaped plate is installed with a controller, and the controller is electrically connected to the micro air pump.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] First, the non-Newtonian fluid phase change fixture, through the set L-shaped plate, rotating plate and pulling rod, when the equipment needs to be used to clamp the workpiece, the workpiece to be processed is directly placed on the processing seat, and then only the pulling rod needs to be pushed downward. At this time, under the action of the pulling rod, the rotating plate and the L-shaped plate can be deflected at an angle, so that the outer wall of the L-shaped plate is parallel to the top of the processing seat, thereby achieving clamping of the workpiece, and the operation is very convenient.
[0013] Second, the non-Newtonian fluid phase change fixture has a fixed block, an air pipe, and a telescopic rod arranged in the inner cavity of the L-shaped plate. When the L-shaped plate is used to clamp and fix the workpiece, the telescopic rod can directly act on the outer wall of the workpiece under the action of a micro air pump. Once the workpiece is deformed during the processing, the telescopic rod can also be firmly attached to the outer wall of the workpiece under the action of the micro air pump to avoid gaps between the workpiece and the fixture.

[0022] By setting the processing seat 2 on the top of the base 1, when the workpiece needs to be clamped and processed, the workpiece can be directly placed on the top of the processing seat 2, and then the pull rod 6 is pressed downward. The workpiece can be clamped under the action of the pull rod 6 and the rotating plate 4 and the L-shaped plate 5, so that the workpiece is fixed on the top of the processing seat 2.
[0023] In a preferred embodiment, one end of the rotating plate 4 away from the fixed plate 3 is rotatably connected to the outer wall of the pull rod 6 , there are two fixed plates 3 , and the two fixed plates 3 are respectively mounted on the top of the base 1 .
[0024] By rotatably connecting the two ends of the rotating plate 4 with the outer walls of the fixed plate 3 and the pulling rod 6 respectively, when the equipment needs to be used to clamp the workpiece, it is only necessary to press the pulling rod 6 downward, so that the rotating plate 4 is pushed to deflect under the action of the pulling rod 6, and then the L-shaped plate 5 is deflected under the action of the pulling rod 6 and the rotating plate 4. At this time, the workpiece can be clamped under the action of the pulling rod 6.
[0025] In a preferred embodiment: the fixed plate 3 , the rotating plate 4 and the L-shaped plate 5 are all made of high carbon steel, and a silicone cushion is installed on the outer edge of the end of the telescopic rod 8 away from the air pipe 9 .
[0026] The fixed plate 3, the rotating plate 4 and the L-shaped plate 5 made of high carbon steel can have better strength during use, so as to better clamp the workpiece under the action of the pulling rod 6.
[0027] In a preferred embodiment: the inner wall of the movable cavity 10 away from the end of the trachea 9 is fixedly equipped with a limit ring, and the outer wall of the telescopic rod 8 close to the end of the trachea 9 is fixedly equipped with a limit ring.
[0028] By respectively setting a limiting ring and a limiting circle at the bottom of the inner cavity of the active chamber 10 and the top of the telescopic rod 8, when the air pipe 9 introduces air into the inner cavity of the active chamber 10, the telescopic rod 8 will move downward under the action of the air, but the limiting ring and the limiting circle will prevent the telescopic rod 8 from escaping from the inner cavity of the active chamber 10, thereby ensuring that the telescopic rod 8 can be better telescoped in the inner cavity of the active chamber 10.
[0029] In a preferred embodiment, the inner cavity of the air pipe 9 is communicated with the inner cavity of the connecting pipe 11 , and the inner cavities of the connecting pipe 11 are respectively connected to the air pipes 9 on the top of the plurality of fixing blocks 7 .

[0031] In a preferred embodiment, one end of the transmission tube 13 away from the connecting tube 11 is connected to the air outlet of the micro air pump 12 , a controller is installed on the outer wall of the L-shaped plate 5 , and the controller is electrically connected to the micro air pump 12 .
[0032] By connecting the two ends of the transmission tube 13 to the connecting tube 11 and the micro air pump 12 respectively, the gas can be passed into the inner cavity of the active chamber 10 through the transmission tube 13 and the connecting tube 11 under the action of the micro air pump 12, thereby driving the telescopic rod 8 in the inner cavity of the active chamber 10, so that the outer wall of the telescopic rod 8 fits against the outer wall of the workpiece.
[0033] When the utility model is in use, when it is necessary to use the equipment to clamp and fix the workpiece, first place the workpiece to be processed on the top of the processing seat 2, and then pull the pull rod 6 downward. At this time, the angle of the rotating plate 4 is tilted under the action of the pull rod 6, and the L-shaped plate 5 is offset at an angle under the action of the pull rod 6 and the rotating plate 4, so that the outer wall of the L-shaped plate 5 is parallel to the top of the processing seat 2, and then the micro air pump 12 is started again. At this time, under the action of the micro air pump 12, air is passed into the inner cavity of the active cavity 10 through the transmission pipe 13, the connecting pipe 11, and the air pipe 9, so as to drive the telescopic rod 8, so that the outer wall of the telescopic rod 8 and the outer wall of the workpiece are in contact with each other. At this time, under the action of the micro air pump 12, the telescopic rod 8 can be kept in a fixed position and not move, so as to clamp and fix the workpiece, that is, the workpiece is deformed during the grinding process during use, and at this time, the telescopic rod 8 can be driven to move under the action of the micro air pump 12, so that the outer wall of the telescopic rod 8 can always be in contact with the outer wall of the workpiece, thereby better achieving the clamping effect of the workpiece.
