Description

Technical Field

[0001] This utility model relates to the technical field of nut processing equipment, specifically a nut processing surface polishing device. Background Technology

[0002] Nuts are parts that tightly connect mechanical equipment. They are joined together by internal threads, and only nuts and bolts of the same specifications can be connected. During the manufacturing process of nuts, their surfaces need to be polished. Existing nut surface polishing equipment generally requires hand-holding the nut on a grinding belt for polishing. This method is not only inefficient and poses safety hazards, but it also allows for polishing only one nut at a time, resulting in slow polishing speed and low polishing quality.

[0003] A prior art patent application number 202420808961.4 describes a nut processing surface polishing device, which includes a frame and a polishing device connected to the upper side of the frame. By setting up the frame, a moving device, the polishing device, and a placement plate in cooperation, the side of the nut can be polished. This overcomes the disadvantage of traditional workers holding the nut to be polished by hand, improves the polishing quality and speed of the nut, and also improves the safety of workers during nut processing. However, the upper and lower end faces of the nut are prone to rotation and movement during polishing, which affects the efficiency of nut processing surface polishing. Utility Model Content

[0004] The purpose of this invention is to provide a nut processing surface polishing device to solve the problem in the prior art that the upper and lower end faces of the nut are prone to rotation and movement during polishing, which affects the efficiency of nut processing surface polishing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nut processing surface polishing device, including a base, a support frame on the upper side of the base, a polishing seat rotatably mounted on the inner wall of the support frame via a connecting shaft, a third motor being connected to one end of the connecting shaft via a gear set, a positioning plate being engaged in the polishing groove inside the polishing seat, and the positioning plate having multiple positioning holes for limiting the insertion of the nut, a lower polishing wheel being mounted at the bottom of the polishing groove via a first motor and a transmission shaft, a lifting plate being mounted on the top of the support frame via a hydraulic cylinder, and an upper polishing wheel being mounted at the lower end of the lifting plate via a second motor.

[0006] Furthermore, the gear set is a reduction gear, and the third motor is fixedly installed on the inner wall of the frame.

[0007] Furthermore, the support frame is configured as an inverted U-shaped bracket, and the outer wall of the support frame is equipped with a PLC control cabinet for overall operation.

[0008] Furthermore, the positioning holes are arranged in a circular array of multiple holes, and the positioning holes are configured as regular hexagonal holes.

[0009] Furthermore, the inner wall of the polishing groove is provided with a limiting rib, and the outer wall of the positioning plate is provided with a limiting groove that engages with the limiting rib.

[0010] Furthermore, the limiting rib is configured as a semi-cylindrical rib, and the limiting groove is configured as a semi-circular groove.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the utility model, a nut processing surface polishing device includes a base 1, a support frame 2 on the upper side of the base 1, a polishing seat 4 rotatably mounted on the inner wall of the support frame 2 via a connecting shaft 3, a third motor 8 being driven to one end of the connecting shaft 3 via a gear set 7, a positioning plate 5 being engaged in the polishing groove 13 inside the polishing seat 4, and a plurality of positioning holes 6 for inserting and limiting the nut in the positioning plate 5, the positioning holes 6 being arranged in a circular array and being set as regular hexagonal holes, the positioning holes 6 in the positioning plate 5 can be used to longitudinally insert and limit the nut to be processed, preventing the nut from rotating and moving during polishing of the upper and lower end faces, thus improving the efficiency of nut processing surface polishing.

[0022] like Figure 1 and Figure 3 As shown, in order to polish both the upper and lower cut surfaces of the nut simultaneously, a lower polishing wheel 14 is provided at the bottom of the polishing groove 13 via a first motor 16 and a drive shaft 15. The first motor 16 drives the drive shaft 15 and the lower polishing wheel 14 to rotate at high speed, which can polish the lower cut surface of the nut. A lifting plate 10 is provided at the top of the support frame 2 via a hydraulic cylinder 9. An upper polishing wheel 12 is provided at the lower end of the lifting plate 10 via a second motor 11. The hydraulic cylinder 9 drives the lifting plate 10 and the second motor 11 to move down, and the high-speed rotating upper polishing wheel 12 is used to polish the upper cut surface of the nut. Polishing both cut surfaces simultaneously greatly improves the polishing efficiency of the cut surfaces at both ends of the nut.

[0023] like Figure 1As shown, in order to unload the polished nuts, the gear set 7 is a reduction gear, and the third motor 8 is fixedly installed on the inner wall of the stand 2. The stand 2 is set as an inverted U-shaped support, and the outer wall of the stand 2 is equipped with a PLC control cabinet for overall operation. The third motor 8 and the gear set 7 drive the connecting shaft 3 to rotate forward and backward, thereby adjusting the longitudinal rotation of the polishing seat 4.

The limiting rib 17 is set as a semi-cylindrical rib, and the limiting groove 18 is set as a semi-circular groove. The limiting groove 18 and the limiting rib 17 can be used to perform horizontal limiting treatment on the positioning plate 5 inserted in the polishing tank 13, so as to prevent the positioning plate 5 from rotating horizontally during polishing and affecting the polishing efficiency.

[0025] The working principle and usage process of this utility model are as follows: When in use, the nut to be processed is inserted longitudinally into the positioning hole 6 of the positioning plate 5. Then, the lifting plate 10 and the second motor 11 are driven to move down by the hydraulic cylinder 9. The upper polishing wheel 12, which rotates at high speed, is used to polish the upper cut surface of the nut. At the same time, the transmission shaft 15 and the lower polishing wheel 14 are driven to rotate at high speed by the first motor 16 to polish the lower cut surface of the nut. Polishing the two cut surfaces at the same time greatly improves the polishing efficiency of the cut surfaces at both ends of the nut.
