Description

Technical Field

[0001] This utility model relates to the field of grinding and polishing equipment technology, and in particular to a burr removal device for screws. Background Technology

[0002] Screws are tools that use the physical and mathematical principles of inclined planes, circular rotation, and friction to gradually fasten objects and machine parts. During screw processing, wear, chips, and incomplete removal of material at the end of the cutting trajectory can create large, sharp burrs. Poor quality or insufficient lubricant, as well as improper machine parameter settings (such as excessively fast feed speed or excessively slow rotation speed), can all easily lead to thread burrs. These burrs not only affect the appearance of stud bolts but also negatively impact the assembly process, potentially causing loose connections, stress concentration, and even breakage.

[0003] When removing burrs from screws, a magnetic grinder is usually used. The magnetic force drives the steel needle to rotate rapidly, grinding away the burrs. For example, Chinese Patent Publication No. CN216576952U discloses "a magnetic grinder", which has a moving device embedded in the plate on the connecting plate. The position of the magnetic pole block can be adjusted by a ball screw motor, which greatly improves the grinding efficiency.

[0004] However, in actual use, when the magnetic grinder grinds screws, the high-speed rotation of the steel needles and screws generates centrifugal force. When the screws and steel needles inside are not evenly distributed, the centrifugal force is easily altered, causing the grinding barrel to shake and deviate from its position, affecting the processing effect. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the centrifugal force generated by the high-speed rotation of steel needles and screws, which easily causes the grinding barrel to shake and deviate from its position. Therefore, this invention proposes a screw burr removal device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a burr removal device for screws, including a grinding machine body and a grinding barrel. The grinding machine body is equipped with a driving device and an electromagnet. The grinding machine body is equipped with two limiting plates that clamp and fix the grinding barrel. A linkage mechanism is provided between the two limiting plates. The grinding machine body is equipped with a driving mechanism that controls the position of the limiting plates. Each limiting plate is fixedly equipped with an arc-shaped plate that cooperates with the grinding barrel.

[0008] Furthermore, the linkage mechanism includes a base plate, and connecting rods are rotatably arranged on both sides of the base plate, with the two connecting rods respectively rotatably connected to the two arc-shaped plates.

[0009] Furthermore, the grinding machine body is provided with a positioning groove that mates with the base plate, and a telescopic rod connected to the base plate is provided in the positioning groove.

[0010] Furthermore, the driving mechanism includes a connecting plate fixedly connected to the grinding machine body, and a tension spring is provided between the connecting plate and the limiting plate.

[0011] Furthermore, a guide rail is fixedly installed on the main body of the grinding machine, and a guide groove that cooperates with the guide rail is provided on the limiting plate.

[0012] Furthermore, a limiting part that cooperates with the limiting plate is fixedly provided on the guide rail, and a buffer pad is fixedly provided on the side of the limiting part close to the limiting plate.

[0013] The burr removal device for screws proposed in this utility model has the following advantages:

[0014] In this utility model, the grinding barrel is clamped and fixed by setting a limiting plate. When the grinding barrel is not placed, the limiting plate is moved by the driving device to increase the distance between the two limiting plates, so as to facilitate the placement of the grinding barrel between the two limiting plates.

[0015] Secondly, in this utility model, when placing the grinding barrel, the bottom plate of the grinding barrel is pressed down to make it move downward. During the downward movement of the bottom plate, the angle of the connecting rod changes, pulling the limiting plate to move. The grinding barrel is clamped and fixed by the two limiting plates to prevent shaking during stirring. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A burr removal device for screws includes a grinding machine body 1 and a grinding barrel 2. The grinding machine body 1 is equipped with a drive device 3, and a ring electromagnet 4 is installed on the drive device 3. The grinding machine body 1 is equipped with two limiting plates 5, which clamp and fix the grinding barrel 2. A linkage mechanism 6 is provided between the two limiting plates 5. The grinding machine body 1 is equipped with a drive mechanism 7 that controls the position of the limiting plates 5. Each limiting plate 5 is fixedly equipped with an arc-shaped plate that cooperates with the grinding barrel 2.

[0023] In this utility model, when the grinding barrel 2 is not placed, the driving mechanism 7 pulls the limiting plate 5 to move, increasing the distance between the two limiting plates 5, so that the grinding barrel 2 can be placed between the two limiting plates 5. When the grinding barrel 2 is placed, the linkage mechanism 6 pulls the limiting plate 5 to move, and the two limiting plates 5 clamp and fix the grinding barrel 2 to prevent it from shaking and misaligning during stirring.

[0024] Furthermore, in this embodiment, the linkage mechanism 6 includes a base plate 61, and connecting rods 62 are rotatably provided on both sides of the base plate 61. The two connecting rods 62 are rotatably connected to two arc-shaped plates respectively. When the grinding barrel 2 presses down on the base plate 61 to make it move downward, the angle of the connecting rods 62 changes during the downward movement of the base plate 61, thereby pulling the limiting plate 5 to move, and clamping and fixing the grinding barrel 2 through the two limiting plates 5.

[0025] Furthermore, in this embodiment, the grinding machine body 1 is provided with a positioning groove that cooperates with the base plate 61. After the base plate 61 moves down, it will be hidden in the positioning groove to prevent uneven force on the bottom of the grinding barrel 2 from affecting the balance. A telescopic rod 63 connected to the base plate 61 is provided in the positioning groove. By setting the telescopic rod 63, the movement trajectory of the base plate 61 is restricted to prevent it from deviating from the preset trajectory when it moves down.

[0026] It should be noted that, in this embodiment, the drive mechanism 7 includes a connecting plate 71 fixedly connected to the grinding machine body 1. A tension spring 72 is provided between the connecting plate 71 and the limiting plate 5. The tension spring 72 pulls the limiting plate 5 to move, increasing the distance between the two limiting plates 5, so that the grinding barrel 2 can be placed between the two limiting plates 5.

[0027] Furthermore, in this embodiment, a guide rail 73 is fixedly installed on the grinding machine body 1, and a guide groove that cooperates with the guide rail 73 is opened on the limiting plate 5 to prevent the limiting plate 5 from deviating from its position during movement, which would cause the two limiting plates 5 to not correspond, or cause the grinding barrel 2 and the electromagnet 4 to not correspond after the two limiting plates 5 clamp the grinding barrel 2.

[0028] More specifically, in this embodiment, a limiting part 74 that cooperates with the limiting plate 5 is fixedly provided on the guide rail 73. The movement range of the limiting plate 5 is limited by the limiting part 74 to prevent excessive force between the connecting rod 62 and the base plate 61 from affecting the service life. A buffer pad is fixedly provided on the side of the limiting part 74 near the limiting plate 5.

[0029] Working method: When the grinding barrel 2 is not placed, the tension spring 72 pulls the limiting plate 5 to move, increasing the distance between the two limiting plates 5, so that the grinding barrel 2 can be placed between the two limiting plates 5. The grinding barrel 2 presses down on the bottom plate 61 to move it down. During the downward movement of the bottom plate 61, the angle of the connecting rod 62 changes, thereby pulling the limiting plate 5 to move. The grinding barrel 2 is clamped and fixed by the two limiting plates 5.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
