DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0030] Refer to Figures 1-3, a magnetic work fixture, including a fixed table 1, on the top of the fixed table 1, there is a positioning component 2 which is convenient for positioning the circular workpiece. There are five positioning components 2, and the five positioning components 2 are distributed in a circumferential array on the top of the fixed table 1;

[0031] The positioning component 2 includes a positioning box 21 fixedly connected to the fixed table 1. The inner top wall and inner bottom wall of the positioning box 21 are both inclined. The outer side wall of the positioning box 21 is slidably connected with a positioning rod 22. The positioning rod 22 is made of magnetic material and is inclined. One end of the positioning rod 22 is fixedly connected with a first electromagnet 23. The outer side wall of the positioning rod 22 is slidably connected with a second electromagnet 24. The magnetic poles on the adjacent sides of the first electromagnet 23 and the second electromagnet 24 are different. The inner side wall of the positioning box 21 is provided with a third electromagnet 25. The center points of the first electromagnet 23, the second electromagnet 24 and the third electromagnet 25 are located on the same inclined straight line. The first electromagnet 23, the second electromagnet 24 and the third electromagnet 25 are all square magnets with holes, and the models of the first electromagnet 23, the second electromagnet 24 and the third electromagnet 25 are all waxu-100-50-40. The magnetic poles on the adjacent sides of the second electromagnet 24 and the third electromagnet 25 are different. The inner side wall of the third electromagnet 25 is slidably connected with the outer side wall of the positioning rod 22. A first spring 26 is fixedly connected between the first electromagnet 23 and the second electromagnet 24. A second spring 27 is fixedly connected between the second electromagnet 24 and the third electromagnet 25. The first spring 26 and the second spring 27 are both located outside the positioning rod 22. The inclined downward side of the positioning rod 22 is fixedly connected with a clamping block 215. The bottom of the clamping block 215 is provided with a clamping groove 216. The clamping groove 216 is an L-shaped groove;

[0032] After the circular workpiece moves to the fixed table 1, the second electromagnet 24 is first energized. The first electromagnet 23 drives the positioning rod 22 to move obliquely downward in the direction close to the circular workpiece. Through the action of the clamping groove 216, the clamping block 215 moves to be closely attached to the edge of the circular workpiece, so as to position the circular workpiece. When the third electromagnet 25 is energized, the second electromagnet 24 moves in the direction close to the third electromagnet 25, so as to adjust the position of the clamping block 215 again, and thus it is convenient to position circular workpieces of different sizes.

[0033] Refer to Figure 3 , the clamping block 215 is fixedly connected with a gasket 217 through the clamping groove 216. The gasket 217 is mainly composed of rubber material and has a certain elasticity. The longitudinal section of the gasket 217 is L-shaped. The gasket 217 further increases the extrusion effect of the clamping block 215 on the circular workpiece.

[0034] Refer to Figure 2, a first slider 28 is slidably connected to the inner bottom wall of the positioning box 21. A first mounting bracket 29 is fixedly connected to the top of the first slider 28. The first slider 28 is located directly below the first mounting bracket 29. The top of the first mounting bracket 29 is fixedly connected to the bottom of the first electromagnet 23. The first slider 28 and the first mounting bracket 29 increase the stability of the movement of the first electromagnet 23.

[0035] Refer to Figure 2 , a second slider 210 is slidably connected to the inner bottom wall of the positioning box 21. A second mounting bracket 211 is fixedly connected to the top of the second slider 210. The second slider 210 is installed at the center of the bottom of the second mounting bracket 211. The top of the second mounting bracket 211 is fixedly connected to the bottom of the second electromagnet 24. The second slider 210 and the second mounting bracket 211 increase the stability of the movement of the second electromagnet 24.

[0036] Refer to Figures 2-3 , a first guiding block 212 is fixedly connected to the top of the first electromagnet 23. The first guiding block 212 is located at the center of the top of the first electromagnet 23. A second guiding block 213 is fixedly connected to the top of the second electromagnet 24. The second guiding block 213 is located at the center of the top of the second electromagnet 24. A guiding rod 214 is fixedly connected to the inner side wall of the positioning box 21. The guiding rod 214 is arranged obliquely. Both the first guiding block 212 and the second guiding block 213 are slidably connected to the guiding rod 214. The guiding rod 214 facilitates the movement and adjustment of the first guiding block 212 and the second guiding block 213, thereby further increasing the accuracy of the movement of the first electromagnet 23 and the second electromagnet 24.

[0037] Refer to Figure 1 , a base 3 is fixedly connected to the bottom of the fixing table 1. A positioning hole 4 is formed in the bottom of the base 3. There are six positioning holes 4, and the six positioning holes 4 are distributed in a circumferential array at the bottom of the base 3. The base 3 and the positioning holes 4 facilitate the installation of the fixing table 1 on the rotating table.

[0038] Refer to Figure 4 , a placement groove 5 is formed in the top of the fixing table 1. The fixing table 1 fits with an aggregate box 6 through the placement groove 5. The placement groove 5 facilitates the placement of the circular workpiece. The aggregate box 6 facilitates the collection of debris generated during the drilling operation of the circular workpiece.

[0039] Working principle: First, the base 3 is installed on the rotating base, and the circular ring-shaped part to be processed is placed inside the placement groove 5. The second electromagnet 24 is first energized, and under the action of the first slider 28 and the first mounting bracket 29, the first electromagnet 23 tilts and moves towards the direction close to the second electromagnet 24. The positioning rod 22 drives the clamping block 215 to move, so that the side of the circular ring-shaped part fits with the card slot 216, and the side of the circular ring-shaped part is in close contact with the clamping block 215, thereby performing a limiting process on the circular ring-shaped part placed on the fixed table 1. After the first electromagnet 23 moves to fit with the second electromagnet 24, the third electromagnet 25 operates. Through the cooperation of the second slider 210 and the second mounting bracket 211, the first electromagnet 23 and the second electromagnet 24 tilt and move towards the direction close to the third electromagnet 25, thereby adjusting the position of the clamping block 215 again, and further facilitating the positioning process of circular ring-shaped parts of different sizes. After the second electromagnet 24 and the third electromagnet 25 are de-energized, under the action of the second spring 27 and the first spring 26, the first electromagnet 23 and the second electromagnet 24 return to the initial position.

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
