A support plate is fixedly connected to the upper surface of the base. A fixing mechanism for fixing the grinding wheel body is arranged on the upper surface of the carrier plate. A rotating mechanism for rotating the grinding wheel body is arranged on the side surface of the support plate. The fixing mechanism is provided, which is beneficial to when it is necessary to fix the grinding wheel body, pulling the two fixing plates, so that the two fixing plates move inside the fixing grooves and move to both sides. The spring is in a compressed state. The grinding wheel body can be first placed on the upper surface of the carrier plate, so that the round hole is vertically aligned with the limiting groove. Loosen the fixing plates.

[0026] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present utility model as follows.

[0027] Please refer to Figures 1-4 As shown, this embodiment provides a technical solution, a grooving device for grinding wheel production, including a placement table 1. A receiving groove 11 for placing the grinding wheel is formed in the top wall of the placement table 1. A convex column 12 is fixedly installed at the center of the bottom end of the inner wall of the receiving groove 11. Two arc-shaped clamping plates 13 for clamping the grinding wheel are symmetrically and horizontally slidably connected in the inner cavity of the receiving groove 11. A rubber anti-slip pad is embedded on the side of the arc-shaped clamping plate 13 close to the grinding wheel. The rubber anti-slip pad is provided to facilitate better clamping of the grinding wheel by the arc-shaped clamping plate 13.

[0028] A driving mechanism for enabling the two arc-shaped clamping plates 13 to move relative to each other is arranged in the inner cavity of the placement table 1. The driving mechanism includes a gear 15 rotatably connected to the top end of the inner cavity of the placement table 1. On both sides of the gear 15 at the top end of the inner cavity of the placement table 1, two racks 16 meshing with the gear 15 are horizontally slidably connected. Two sliding plates 17 are symmetrically slidably connected to the top end of the inner cavity of the placement table 1. The sliding plate 17 is fixedly connected to the arc-shaped clamping plate 13. One end of the rack <16> away from the gear 15 is fixedly connected to the sliding plate 17. Rotating the gear 15 makes the two racks 16 move relative to each other. By driving the two racks 16, the two sliding plates 17 move synchronously, and then drive the two arc-shaped clamping plates 13 to move relative to each other.

[0029] A shielding cover 110 is vertically slidably connected to the outside of the placement table 1. The shape of the shielding cover 110 is circular. A linkage mechanism for enabling the shielding cover 110 to move vertically is arranged in the inner cavity of the placement table 1. The linkage mechanism includes a threaded rod 14 rotatably connected to the inner cavity of the placement table 1. The outer peripheral wall of the threaded rod 14 is fixedly connected to the inner cavity of the gear 15. A nut sleeve 18 slidably connected to the inner cavity of the placement table 1 is threadedly sleeved on the outer peripheral wall of the threaded rod 14 and below the gear 15. Transmission rods 19 are fixedly installed on both sides of the nut sleeve 18. One side of the transmission rod 19 away from the nut sleeve 18 penetrates through the placement table 1 and extends to the outside of the placement table 1. The end of the transmission rod 19 extending to the outside of the placement table 1 is fixedly connected to the shielding cover 110. Rotating the threaded rod 14 makes the nut sleeve 18 move vertically in the inner cavity of the placement table 1.

[0030] A forward and reverse motor 2 for driving the rotation of the threaded rod 14 is fixedly installed at the bottom end of the placement table 1.

[0031] One side of the placement table 1 is provided with a grinding wheel grooving mechanism. The grinding wheel grooving mechanism includes a support frame 3 fixedly connected to one side of the placement table 1. The top wall of the support frame 3 is fixedly installed with a hydraulic telescopic rod 31. The output end of the hydraulic telescopic rod 31 is fixedly installed with a lifting plate 32 that cooperates with the shielding cover 110. The top wall of the lifting plate 32 is fixedly installed with a servo motor 33. The output end of the servo motor 33 is fixedly installed with a rotating disk 34. One side of the rotating disk 34 away from the lifting plate 32 is fixedly installed with a fixed column 35. One side of the fixed column 35 away from the rotating disk 34 is provided with a grooving assembly 36. The grooving assembly 36 includes a driving machine fixedly connected to the fixed column 35. The output end of the driving machine is fixedly installed with a grooving tool;

[0032] The bottom wall of the lifting plate 32 is fixedly installed with a dust suction nozzle group 38. The top wall of the lifting plate 32 is fixedly installed with a dust collection box 37. The dust collection box 37 and the dust suction nozzle group 38 are communicated through a dust suction machine 39.

[0033] When the utility model is in use, the grinding wheel to be grooved is placed in the accommodation groove 11 in the placement table 1. When placing the grinding wheel, the central circular hole of the grinding wheel penetrates through the convex column 12. After placement, the forward and reverse motor 2 is driven to make the threaded rod 14 rotate forward. The threaded rod 14 drives the gear 15 to rotate synchronously. The rotation of the gear 15 drives two racks 16 engaged with it to move towards each other. The movement of the two racks 16 drives the two arc-shaped clamping plates 13 to move synchronously through the sliding plate 17, so as to facilitate clamping both sides of the grinding wheel, and further facilitate fixing the grinding wheel;

[0034] During the process of fixing the grinding wheel, the rotation of the threaded rod 14 drives the sleeve 18 sleeved on its outer peripheral wall to move upward. The sleeve 18 drives the shielding cover 110 to move upward synchronously. The upward movement of the shielding cover 110 facilitates blocking the grinding debris and dust generated by subsequent grooving work;

[0035] Similarly, the reverse rotation of the threaded rod 14 can not only release the limit of the grinding wheel but also reset the shielding cover 110. The reset of the shielding cover 110 facilitates the staff to take out the grooved grinding wheel;

[0036] After the grinding wheel is fixed, the hydraulic telescopic rod 31 is driven to make the lifting plate 32 move downward. The downward movement of the lifting plate 32 can not only make the grooving assembly 36 reach the position to be grooved but also close the shielding cover 110. Finally, the servo motor 33 and the grooving assembly 36 are operated. The servo motor 33 makes the rotating disk 34 rotate. The rotation of the rotating disk 34 makes the fixed column 35 do a circular motion around the center of the rotating disk 34. The movement of the fixed column 35 facilitates driving the grooving assembly 36 to move synchronously, and further facilitates completing the grooving work of the grinding wheel;

[0037] During the process of grooving the grinding wheel, the cooperation of the shielding cover 110 and the lifting plate 32 can prevent the overflow of chips, dust, etc. generated by the grooving operation. Driven by the dust collector 39, the chips, dust, etc. can be collected into the inner cavity of the dust collection box 37 through the dust suction nozzle group 38, thereby reducing the pollution of the working environment by chips, dust, etc., and making the equipment more convenient for the staff to use.

[0038] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
