[0032] Example 1

[0033] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides an intelligent grinding and polishing device suitable for special-shaped parts. The intelligent grinding and polishing device suitable for special-shaped parts includes a carrying component 1, a positioning component 2 and a processing component 3. Through the arrangement of the positioning component 2 and the processing component 3, the positioning component 2 can perform preliminary positioning and then lock special-shaped parts of different shapes, thereby ensuring the stability of the clamping of the special-shaped parts, making the overall operation convenient and the processing efficiency guaranteed.

[0034] Specifically, the bearing assembly 1 includes a support platform 11 , a top of the support platform 11 is provided with an empty slot 11 - 1 , a bottom of the empty slot 11 - 1 is provided with an anti-slip slot 11 - 2 , and an auxiliary frame 12 is fixed on the support platform 11 .

[0035] There is space between the auxiliary frame 12 and the support platform 11 to meet the installation requirements of the processing component 3 to prevent the processing component 3 from affecting the displacement action of the positioning component 2.

[0036] Specifically, the positioning assembly 2 is arranged on the support platform 11, and includes a workbench 21 located at the top of the support platform 11. Storage shells 22 are fixed on both sides of the top of the workbench 21. A positioning rod 23 slides through the storage shell 22. A spring 23-1 is sleeved on the positioning rod 23. A first spring 24 is fixed at the center of the bottom of the workbench 21, and a displacement frame 25 is fixed to the other end of the first spring 24. A fixing frame 26 is fixed to the bottom of the workbench 21, and an anti-slip pressure plate 27 is provided on the fixing frame 26.

[0037] The first spring 24, the displacement frame 25 and the fixing frame 26 are all located in the empty groove 11-1, and the anti-skid pressure plate 27 is located in the anti-skid groove 11-2.

[0038] The side of the fixing frame 26 is provided with a damping device, and the fixing frame 26 is locked, as shown in the accompanying drawings of the specification. Figure 5 As shown, the damping edge on the fixing frame 26 is in close contact with the anti-slip groove 11 - 2 , preventing the entire positioning assembly 2 from being displaced.

[0039] Specifically, the processing component 3 is arranged on the auxiliary frame 12, and includes a turntable 31 rotatably connected to the auxiliary frame 12, a motor 32 is embedded in the turntable 31, a mounting shell 34 is fixed to the output end of the motor 32, a clamping block 34-1 is provided on the outer ring of the mounting shell 34, and a processing head 35 is slidably connected inside the mounting shell 34.

[0040] The turntable 31 is connected to the auxiliary frame 12 via a damping bearing, which is used to increase the friction force that the turntable 31 needs to overcome during rotation, prevent the turntable 31 from rotating at will, and facilitate the operator to adjust the angle of the processing head 35.

[0041] Example 2

[0042] Reference Figures 2 to 7 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0043] Specifically, there are several positioning rods 23 evenly distributed on the storage shell 22 , one end of the spring 23 - 1 is fixed on the positioning rod 23 , and the other end of the spring 23 - 1 is fixed on the storage shell 22 .

[0044] The provision of the spring 23 - 1 can provide elastic supporting force for the positioning rod 23 , and ensure that the plurality of positioning rods 23 can adapt to the surface shape of the special-shaped part when the special-shaped part is installed.

[0045] A guide rod 23 - 2 is fixed to the top of the positioning rod 23 , and a guide groove 22 - 1 is provided in the storage shell 22 and is slidably engaged with the guide rod 23 - 2 .

[0046] The arrangement of the guide rod 23 - 2 and the guide groove 22 - 1 can play a role in positioning and guiding, thereby ensuring the sliding stability of the positioning rod 23 .

[0047] The top of the displacement frame 25 passes through the workbench 21 and is in sliding contact with the workbench 21 . An arc-shaped groove 25 - 1 is formed on the top of the displacement frame 25 .

[0048] The arc groove 25 - 1 is provided with anti-slip grooves for increasing the contact friction with the positioning rod 23 when the positioning rod 23 is locked, thereby preventing the positioning rod 23 from being displaced randomly.

[0049] The arcuate groove 25 - 1 cooperates with the positioning rod 23 , and is used to increase the contact area between the arcuate groove 25 - 1 and the positioning rod 23 when the displacement frame 25 is moved up and locked, thereby completing a good locking of the positioning rod 23 .

[0050] The fixing frame 26 is located outside the first spring 24 . A positioning shaft 26 - 1 is fixed at the center of the fixing frame 26 . The anti-slip pressure plate 27 is movably connected to the positioning shaft 26 - 1 .

[0051] One end of the anti-skid pressure plate 27 is designed to be arc-shaped, and the positioning shaft 26-1 eccentrically passes through the anti-skid pressure plate 27. The anti-skid pressure plate 27 is slidably matched with the anti-skid groove 11-2.

[0052] Through the cooperation between the positioning shaft 26-1 and the anti-skid pressure plate 27, when the anti-skid pressure plate 27 rotates to a horizontal state, the anti-skid pressure plate 27 can squeeze the displacement frame 25 upward so that the displacement frame 25 locks the positioning rod 23. When the anti-skid pressure plate 27 rotates to a vertical state, under the elastic support of the first spring 24, the displacement frame 25 automatically moves downward and no longer contacts the positioning rod 23.

[0053] When the anti-skid pressure plate 27 rotates to a horizontal state, it is embedded in the anti-skid groove 11 - 2 and locked through the rough surface, thereby completing the locking of the positioning assembly 2 .

[0054] An auxiliary groove 34 - 4 is formed on the outer ring of the mounting shell 34 , and an auxiliary block 34 - 11 is fixed to the inner ring of the clamping block 34 - 1 and is slidably engaged with the auxiliary groove 34 - 4 .

[0055] The auxiliary groove 34 - 4 and the auxiliary block 34 - 11 are both T-shaped in cross section, which play a role in positioning and guiding, ensuring the stability of the block 34 - 1 on the mounting shell 34 and preventing the block 34 - 1 from linearly displacing and separating from the mounting shell 34 .

[0056] A second spring 34 - 2 is fixed to one end of the clamping block 34 - 1 , and the other end of the second spring 34 - 2 is fixed in the auxiliary groove 34 - 4 .

[0057] The second spring 34 - 2 can elastically support the clamping block 34 - 1 and prevent the clamping block 34 - 1 from moving randomly without external force.

[0058] There are three processing heads 35, including a rough grinding tool, a fine grinding tool and a polishing tool. A protrusion 35-1 is fixed to the outer ring of the processing head 35. A recessed hole 34-3 for use with the protrusion 35-1 is provided on the mounting shell 34. A card slot 35-11 is provided on the protrusion 35-1 and slides with the card slot 34-1.

[0059] The processing head 35 can be conveniently and accurately inserted into the mounting shell 34 through the protrusion 35 - 1 and the recessed hole 34 - 3 .

[0060] By providing the clamping slot 35 - 11 and the clamping block 34 - 1 , it is possible to prevent the processing head 35 from moving arbitrarily and being separated from the mounting shell 34 when the clamping block 34 - 1 is placed in the clamping slot 35 - 11 .

[0061] A locking bolt 33 is threadedly connected to the auxiliary frame 12 , and one end of the locking bolt 33 is in close contact with the turntable 31 .

[0062] The auxiliary frame 12 is provided with a screw hole that cooperates with the locking bolt 33 , and the locking bolt 33 is screwed in to press and lock the turntable 31 .

[0063] When in use, the special-shaped piece is first moved down to the workbench 21, and the side contacts the multiple positioning rods 23, the corresponding springs 23-1 are stretched, and the multiple positioning rods 23 complete the preliminary positioning of the special-shaped piece.

[0064] According to the requirements of grinding and polishing of special-shaped parts, the processing head 35 with different processing accuracy is moved into the mounting shell 34. With the cooperation of the protrusion 35-1 and the recessed hole 34-3, the convenience and accuracy of operation are guaranteed. At the same time, the block 34-1 is rotated clockwise, and the second spring 34-2 is compressed. After the processing head 35 is inserted, the slot 35-11 is aligned with the block 34-1. The block 34-1 is released and under the elastic support of the second spring 34-2, the block 34-1 is reset to the slot 35-11, completing the locking of the processing head 35.

[0065] Move and adjust the position of the workbench 21, and rotate and adjust the position of the processing head 35. After both are adjusted, the anti-skid pressure plate 27 is rotated to a horizontal state, the extrusion displacement frame 25 is moved upward, the first spring 24 is compressed, and the arc groove 25-1 completes the locking of the positioning rod 23, thereby ensuring the positioning stability of the special-shaped part. At this time, the anti-skid pressure plate 27 is placed as a whole in the anti-skid groove 11-2 to ensure the position stability of the workbench 21, and then the locking bolt 33 is screwed in to tighten the turntable 31 to maintain the angle and position of the turntable 31 and the processing head 35.

[0066] The control motor 32 can make the mounting shell 34 and the processing head 35 rotate simultaneously, which is used to grind or polish the surface of the special-shaped part. During actual operation, the operator can change the position of the special-shaped part by moving the workbench 21 and change the position of the processing head 35 by rotating the turntable 31, so that the special-shaped part can be well processed.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
