[0002] The grinding process is an indispensable processing technology for die-casting products, sheet metal products, and casting products. Nowadays, grinding is generally divided into manual or mechanical automation. Manual grinding is time-consuming and energy-consuming, and the most unreliable thing is that the quality is difficult to guarantee. Common phenomena include product deformation and incomplete operation.

[0003] After retrieval, the Chinese patent publication number: CN 215824983 U discloses a burr grinding tooling for automatic equipment spare parts, which relates to the field of spare parts.

[0031] 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 embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figures 1-3 , an embodiment provided by the present utility model: an automatic grinding tooling, including a workbench 1. A motor 2 is fixedly connected to the left outer wall of the workbench 1. A reciprocating lead screw 3 is rotatably connected to the inner wall of the workbench 1. The reciprocating lead screw 3 is a prior art, and its surface is provided with two sets of positive and negative threads. By rotating it, the moving seat 51 on its surface can be reciprocally adjusted and moved. The output shaft of the motor 2 is fixedly connected to the reciprocating lead screw 3. The moving seat 51 is threadedly connected to the surface of the reciprocating lead screw 3. By moving the moving seat 51 on the surface of the reciprocating lead screw 3, the workpiece can be made to move horizontally on the surface of the moving seat 51 following it, so as to grind at multiple angles. The moving seat 51 is slidably connected to the inner wall of the workbench 1. A connecting plate 4 is fixedly connected to the top of the outer wall of the workbench 1. An electric telescopic rod 6 is fixedly connected to the outer wall of the top of the connecting plate 4. A grinding disc 8 is arranged at the bottom end of the outer wall of the electric telescopic rod 6. The grinding disc 8 is a prior art, and a driving motor is arranged inside it. By starting it, the grinding disc 8 rotates at a high speed to grind the surface of the workpiece. A protection component 7 is arranged on the outer wall of the electric telescopic rod 6.

[0033] Referring to Figures 2-5The inner wall of the workbench 1 is provided with a fixing assembly 5, which includes a moving seat 51. The inner wall of the moving seat 51 is rotatably connected with a rotating disk 53. Two sets of arc grooves are provided on the surface of the rotating disk 53. The clamping block 54 is slidably connected to the inner wall of the arc groove of the rotating disk 53. By rotating the rotating disk 53, the bottom end of the clamping block 54 moves in the arc groove, so as to move toward each other or away from each other. The fixing block 52 is slidably connected to the inner wall of the moving seat 51. The shape of the fixing block 52 matches the arc groove provided on the surface of the moving seat 51, and the rotating disk 53 can be driven to move in the inner wall of the moving seat 51 by moving the fixing block 52. The top of the outer wall of the rotating disk 53 is fixedly connected with a fixed block 52, and the inner wall of the moving seat 51 is slidably connected with two groups of clamping blocks 54. The surface of the moving seat 51 is provided with two groups of linear guide grooves, so that when the clamping blocks 54 move toward the inner wall of the rotating disk 53, no arc movement will be generated, and only lateral movement can be performed. The inner wall of the fixed block 52 is elastically connected with a pressing block 56 through a limiting spring 55. One end of the limiting spring 55 is fixedly connected to the inner wall of the fixed block 52, and the other end of the limiting spring 55 is fixedly connected to the outer wall of the pressing block 56. The function of the limiting spring 55 is to reset the position of the pressing block 56 when it moves. The pressing block 56 is slidably connected to the inner wall of the fixed block 52, and the inner wall of the moving seat 51 is provided with multiple groups of card slots. The pressing block 56 is plugged into the inner wall of the card slot. The plugging between the two fixes the rotating disk 53 at multiple positions of the inner wall of the moving seat 51 when it rotates.

[0034] Reference Figure 1 and Figure 5 , the protection component 7 includes a shielding cover 72, which is elastically connected to the outer wall of the bottom end of the electric telescopic rod 6 through a return spring 71, one end of the return spring 71 is fixedly connected to the top of the outer wall of the shielding cover 72, and the other end of the return spring 71 is fixedly connected to the inner wall of the bottom end of the electric telescopic rod 6. The function of the return spring 71 is to automatically reset the position of the shielding cover 72 after it is squeezed and moved. The shielding cover 72 is slidably connected to the outer wall of the bottom end of the electric telescopic rod 6. The bottom end of the electric telescopic rod 6 is provided with a guide groove, so that the shielding cover 72 can only move up and down on the inner wall of the guide groove and cannot be separated from its inner wall.

[0035] Working principle: When grinding a workpiece, place the workpiece between two clamping blocks 54 on the surface of the moving seat 51. At this time, the pressing block 56 can be moved along the inner wall of the fixed block 52, and the pressing block 56 can be disengaged from the card slot at the current position of the moving seat 51. When the pressing block 56 moves, the limiting spring 55 will be elastically compressed. At this time, the fixed block 52 can be rotated to drive the rotating disk 53 to rotate along the inner wall of the moving seat 51. When the rotating disk 53 rotates, the two clamping blocks 54 sliding in the arc-shaped grooves on its surface will move towards each other. And because the surfaces of the clamping blocks 54 are slidably connected in the linear guide grooves of the moving seat 51, the two clamping blocks 54 will move linearly towards each other, so as to quickly fix the workpiece. At this time, the pressing block 56 can be released, and it will be elastically acted upon by the limiting spring 55 to return to its initial position to be engaged with the card slot at the current position of the moving seat 51, so as to fix the positions of the rotating disk 53 and the clamping blocks 54.

[0036] At this time, the electric telescopic rod 6 can be started to make the grinding disk 8 at the bottom fit the surface of the workpiece. At the same time, during the downward movement of the electric telescopic rod 6, the bottom end of the shielding cover 72 will first contact the surface of the workpiece, and the return spring 71 will be elastically compressed. At this time, the grinding disk 8 can still move downward. When the grinding disk 8 fits the surface of the workpiece, the shielding cover 72 will be elastically acted upon by the return spring 71 and always fit on the surface of the workpiece, so as to block the debris generated during the rotation and grinding of the grinding disk 8.

[0037] When grinding a workpiece at multiple angles at the same position, the motor 2 can be started to drive the reciprocating lead screw 3 to rotate by its output shaft. When the reciprocating lead screw 3 rotates, it will drive the moving seat 51 to move horizontally along the inner wall of the workbench 1, so that it can be adjusted according to the position where the workpiece needs to be ground, without having to release the fixation of the workpiece to adjust the position of the workpiece.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
