Description

Technical Field

[0001] This utility model relates to the field of dovetail clip processing technology, and in particular to a surface polishing device for dovetail clips. Background Technology

[0002] Dovetail clips are a type of stationery made by metal stamping. However, after stamping, their surfaces require polishing and grinding to remove burrs and improve cleanliness, thus ensuring the quality of subsequent dovetail clip production. However, existing polishing equipment often fails to adequately polish the dovetail clips, resulting in poor polishing effects. Therefore, improvements are urgently needed. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a surface polishing device for dovetail clips.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A surface polishing device for a dovetail clip includes a base and a vibrating barrel vibrating on the base. An electromagnet is fixed on the base, and a magnet corresponding vertically to the electromagnet is provided on the vibrating barrel. The base has a recessed bottom plate and a rotating cylinder rotatably mounted on the bottom plate. A stirring plate inclined downward and attached to the bottom plate is connected to the rotating cylinder. A wire brush is provided on the inclined upper surface of the stirring plate. A groove is opened at the bottom of the stirring plate, and an annular protrusion adapted to the groove is provided on the bottom plate.

[0005] Preferably, the rotating drum is provided with connecting rods fixed to the stirring plate in a circumferential direction, the inner wall of the vibrating drum is provided with an annular sliding groove, and the stirring plate is provided with a locking post that is engaged in the sliding groove.

[0006] Preferably, the base plate is provided with a stop cylinder, the rotating cylinder is rotatably fitted to the stop cylinder, and the rotating cylinder is provided with a stop ring that abuts against the upper end of the stop cylinder.

[0007] Preferably, a motor is provided on the base plate, and the output end of the motor is connected to the rotating drum.

[0008] Preferably, the bottom of the vibrating barrel has multiple locking posts circumferentially distributed, and the base is provided with a column corresponding to the position of the locking post 1. The column is inserted into the locking post 1, and a spring is provided between the column and the locking post 1.

[0009] The beneficial effects of this utility model are: A vibrating barrel is installed on the base, and dovetail clips to be polished and abrasive particles are placed inside the vibrating barrel. The vibrating barrel vibrates up and down to ensure that the dovetail clips and abrasive particles make full contact for polishing. At the same time, an inclined stirring plate is rotated inside the vibrating barrel. The rotation of the stirring plate agitates the abrasive particles to prevent them from accumulating at the bottom of the vibrating barrel, thus ensuring more thorough contact between the abrasive particles and the dovetail clips and a better polishing effect. Furthermore, by placing a wire brush on the stirring plate, the dovetail clips are polished using the wire brush during the rotation of the stirring plate, further improving the polishing effect on the surface of the dovetail clips.

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0013] like Figures 1-4 As shown, a surface polishing device for dovetail clips includes a base 1 and a vibrating barrel 2 vibrating on the base 1. The vibrating barrel 2 is spaced above the base 1. The dovetail clips to be polished and abrasive particles for polishing are placed in the vibrating barrel 2. The vibrating barrel 2 vibrates up and down to make the dovetail clips and abrasive particles fully contact each other for polishing.

[0014] Specifically, the bottom of the vibrating barrel 2 has multiple locking posts 21 distributed circumferentially. The lower part of each locking post 21 is hollow. The base 1 is provided with a column 11 corresponding to the position of the locking post 21. The locking posts 21 and the column 11 are distributed in a one-to-one correspondence. The column 11 is inserted into the locking post 21, and a spring 12 is provided between the column 11 and the locking post 21.

[0015] Furthermore, an electromagnet 13 is fixed on the base 1, and a magnet 22 corresponding to the electromagnet 13 is provided on the vibrating barrel 2. The electromagnet 13 is attracted to the magnet 22 on the vibrating barrel 2 by electromagnetic attraction. Then, the electromagnet 13 and the magnet 22 cooperate to drive the vibrating barrel 2 to vibrate up and down so as to use the abrasive particles to vibrate and contact the dovetail clamp for grinding and polishing.

[0016] The base 1 is provided with a recessed base plate 23 and a rotating cylinder 25 rotatably mounted on the base plate 23. The base plate 23 is provided with a stop cylinder 231. The rotating cylinder 25 is rotatably fitted to the stop cylinder 231. The rotating cylinder 25 is provided with a stop ring 251 that abuts against the upper end of the stop cylinder 231. The rotating cylinder 25 is spaced apart on the inner circumference of the stop cylinder 231. The base plate 23 is provided with a motor 252. The output end of the motor 252 is connected to the rotating cylinder 25 so as to drive the rotating cylinder 25 to rotate.

[0017] The rotating drum 25 is connected to a stirring plate 3 that is inclined downward and attached to the bottom plate 23. That is, the stirring plate 3 is rotatably arranged inside the vibrating drum 2, and the lower part of the stirring plate 3 is attached to the contour of the concave bottom plate 23.

[0018] Specifically, the rotating drum 25 is circumferentially distributed with connecting rods 26 fixed on the stirring plate 3. The rotation of the rotating drum 25 drives the stirring plate 3 to rotate synchronously. The rotation of the stirring plate 3 stirs the grinding particles to prevent them from accumulating at the bottom of the vibrating drum 2. That is, the stirring plate 3 can stir the grinding particles accumulated at the bottom of the vibrating drum 2 upward, so that the grinding particles can contact the dovetail clamps multiple times for grinding. This makes the grinding particles and the dovetail clamps have more sufficient contact for grinding, resulting in a better grinding and polishing effect.

[0019] Furthermore, the inner wall of the vibrating barrel 2 is provided with an annular groove 24, and the stirring plate 3 is provided with a locking post 32 that is engaged in the groove 24. The locking post 32 cooperates with the groove 24 to guide the circumferential rotation of the stirring plate 3, so as to make the rotation of the stirring plate 3 more stable.

[0020] Furthermore, the bottom of the stirring plate 3 is provided with a slot 31, and the bottom plate 23 is provided with an annular protrusion 232 that is adapted to the slot 31. The protrusion 232 is engaged in the slot 31, and the stirring plate 3 is more stable when rotating by the cooperation between the protrusion 232 and the slot 31, making the stirring operation of the stirring plate 3 smoother and more reliable.

[0021] A wire brush 33 is provided on the inclined upper surface of the stirring plate 3, so that the dovetail clip is polished by the wire brush 33 during the rotation of the stirring plate 3, so as to further improve the polishing effect on the surface of the dovetail clip.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
