[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 3As shown, a surface grinder fixture comprises a base 1, a workbench 3 is fixedly installed on the upper end of the base 1 through four supporting columns 2, a clamping assembly 2 7 is arranged at the middle position on the upper end of the workbench 3, the clamping assembly 2 7 comprises two limiting triangles 8, the two limiting triangles 8 are arranged vertically, three electric telescopic rods 10 are fixedly installed on the upper end of the limiting triangle 8 located at the lower end, and the upper end of the electric telescopic rod 10 is fixedly connected to the lower end of the limiting triangle 8 located at the upper end, and through grooves 11 are opened on both sides of the limiting triangle 8, a cavity is arranged inside the limiting triangle 8, the inside of the through groove 11 passes through a limiting plate 12, and a cartridge 13 is fixedly installed on one side of the limiting plate 12, when grinding one end of a circular workpiece, multiple groups of circular workpieces are passed through the inside of the two limiting triangles 8, and the electric telescopic rod 10 is started through the setting of the clamping assembly 2 7, so that the limiting triangle 8 located at the upper end is close to the outside of the upper end of the circular workpiece.

[0022] In this embodiment, a bolt 14 is threaded through one side of the limiting triangle 8, and one end of the bolt 14 is movably engaged in the interior of the clamping cylinder 13. The bolt 14 is rotated to drive the limiting plate 12 to move toward the direction of the circular workpiece, thereby pressing and limiting the circular workpiece, which is convenient for grinding the upper end of the circular workpiece.

[0023] In this embodiment, three guide pillars 91 are fixedly installed at the lower end of the lower limiting triangle 8, and an electromagnetic suction cup 9 is fixedly installed at the lower end of the guide pillar 91. Three sockets 15 matching the electromagnetic suction cup 9 are opened at the upper end of the workbench 3. When the electromagnetic suction cup 9 is energized, the coil inside it generates a magnetic field, thereby adsorbing the surface of the ferromagnetic object. Since the workbench 3 is made of metal iron, after the electromagnetic suction cup 9 is energized, the guide pillar 91 drives the electromagnetic suction cup 9 to move to the bottom of the socket 15, so that the electromagnetic suction cup 9 is adsorbed on the bottom end of the socket 15, so that the entire clamping assembly 2 7 is fixed above the workbench 2.

[0024] In this embodiment, a clamping assembly 4 is disposed at the upper end of the workbench 3 , and the clamping assembly 4 includes two clamping substrates 16 .

[0025] In this embodiment, two threaded sliders 17 are fixedly installed at the lower end of the clamping base plate 16, and two slide grooves 6 are provided at the upper end of the workbench 3. The threaded sliders 17 are located inside the slide grooves 6. When the planar workpiece is polished, the electromagnetic suction cup 9 is powered off, the clamping component 2 7 is removed, and the planar workpiece is placed on the workbench 3. The two servo motors 21 are started through the set clamping component 4.

[0026] In this embodiment, two servo motors 21 are fixedly installed on one side of the workbench 3, and a bidirectional threaded rod 22 is fixedly installed on one end of the output shaft of the servo motor 21. The bidirectional threaded rod 22 passes through the interior of the slide groove 6 and is threadedly connected to the threaded slider 17. After the bidirectional threaded rod 22 rotates, it drives the two threaded sliders 17 to move relative to each other, thereby causing the two clamping base plates 16 to move relative to each other, thereby clamping the planar workpiece to facilitate later grinding.

[0027] In this embodiment, a reinforcement plate 18 is arranged above the clamping substrate 16, and two electromagnetic suction cups 19 are also fixedly installed on the lower end of the reinforcement plate 18 by two guide pillars 91. After the electromagnetic suction cup 19 is energized, the guide pillars 91 drive the electromagnetic suction cup 19 to move toward the circular hole 20, so that the electromagnetic suction cup 19 is adsorbed on the bottom of the circular hole 20 at the upper end of the clamping substrate 16, which is convenient for fixing the reinforcement plate 18. The upper ends of the reinforcement plate 18 and the clamping substrate 16 are both provided with circular holes 20. When the height of the planar workpiece is high, in order to achieve a better clamping effect, multiple groups of reinforcement plates 18 can be added to increase the clamping force of the clamping substrate 16, so that the planar workpiece is more stable during grinding, and when clamping, in order to ensure that the upper surface of the planar workpiece is located above the clamping substrate 16, the reinforcement plate 18 can be removed to prevent the reinforcement plate 18 from obstructing the operation of the grinder.

[0028] The implementation principle of a surface grinder fixture in the embodiment of the present application is as follows: when grinding one end of a circular workpiece, multiple groups of circular workpieces are passed through the interior of two limiting triangles 8, and the electric telescopic rod 10 is started through the provided clamping assembly 27, so that the limiting triangle 8 located above is close to the outside of the upper end of the circular workpiece, and the bolt 14 is rotated so that the bolt 14 drives the limiting plate 12 to move in the direction of the circular workpiece, and the circular workpiece is pressed and limited, so as to facilitate the grinding of the upper end of the circular workpiece. When grinding the flat workpiece, the electromagnetic suction cup 19 is powered off, the clamping assembly 27 is removed, and the flat workpiece is placed on the workpiece. On the table 3, through the clamping assembly 4 set, the two servo motors 21 are started, and after the bidirectional threaded rod 22 rotates, the two threaded sliders 17 are driven to move relative to each other, so that the two clamping base plates 16 move relative to each other, and then the planar workpiece is clamped to facilitate later grinding. When the height of the planar workpiece is high, in order to achieve a better clamping effect, multiple sets of reinforcement plates 18 can be added to increase the clamping force of the clamping base plate 16, so that the planar workpiece is more stable during grinding, and when clamping, in order to ensure that the upper surface of the planar workpiece is located above the clamping base plate 16, the reinforcement plate 18 can be removed to prevent the reinforcement plate 18 from obstructing the work of the grinder.
