Description

Technical Field

[0001] This utility model relates to the field of wire drawing equipment technology, and in particular to a wire drawing machine device with force control function in the grinding process. Background Technology

[0002] Surface brushing is a surface treatment method that creates lines on the surface of a workpiece through grinding, achieving a decorative effect. Because surface brushing can highlight the texture of metallic materials, it has gained increasing popularity and widespread application. However, in existing technologies, the force exerted by the brushing roller assembly in contact with the metal surface is difficult to control. Furthermore, in automated production, wear and tear on the brushing roller assembly over time reduces the friction between the assembly and the metal surface, resulting in significant variations in the brushed lines or an unsatisfactory brushing effect. Therefore, ensuring the quality of the brushed lines is a problem that those skilled in the art need to consider. Utility Model Content

[0020] The present invention will be further described in detail below with reference to specific embodiments:

[0021] like Figures 1-3 As shown, this invention is applied to the wire drawing process of metal surfaces. Driven by a robotic arm, the wire drawing wheel contacts the metal surface and reciprocates; simultaneously, driven by a drive device, the wire drawing wheel rotates, causing the metal surface to form wires. Of course, besides wire drawing, this invention can also replace the wire drawing wheel with a grinding wheel or polishing wheel for grinding and polishing metals or other materials.

[0022] Specifically, a wire drawing machine device with force control function during the grinding process includes a robotic arm 1, a mounting plate 2 connected to the robotic arm 1, and two symmetrical fixed plates 3 fixedly connected to the mounting plate 2. Each of the two fixed plates 3 has a clamping plate 4 connected to one side away from each other, and the clamping plate 4 is rotatably connected to the fixed plate 3. A drive device 5 is fixedly connected between the two fixed plates 3. The drive end (drive shaft) of the drive device 5 passes through the fixed plate 3 and the clamping plate 4 and is connected to a first pulley 51. The axis of rotation of the drive device 5 coincides with the axis of rotation of the clamping plate 4 and the fixed plate 3.

[0023] A wire drawing wheel 6 is rotatably connected between the two clamping plates 4. One end of the shaft of the wire drawing wheel 6 passes through the clamping plate 4 and is provided with a second pulley 61. The second pulley 61 is connected to the first pulley 51 through a belt 7. That is, when the driving device 5 drives the rotation, the wire drawing wheel 6 can be driven to rotate through the belt 7.

[0024] A connecting rod 41 is also connected between the two clamping plates 4, and a force control device 8 is rotatably connected to the connecting rod 41. A connecting seat 81 is fixedly connected to the end of the force control device 8 away from the connecting rod 41, and the connecting seat 81 is rotatably connected to the mounting plate 2.

[0025] In this embodiment, the axial direction of the rotating connection between the connecting seat 81 and the mounting plate 2 is parallel to the axial direction of the rotating connection between the force control device 8 and the connecting rod 41 and the axial direction of the rotating connection between the clamping plate 4 and the fixing plate 3, and they are not on the same plane.

[0026] During metal wire drawing, the drive unit 5 drives the drawing wheel 6 to rotate via the belt 7. The robotic arm 1 drives the drawing wheel 6 to contact the metal surface and reciprocate on the metal surface, forming wire. During this process, the force of the drawing wheel 6 contacting the metal surface causes the clamping plate 4 to rotate towards the force control device 8, which then transmits the force to the force control device 8. If the force exceeds the preset range of the force control device 8, the force control device 8 will retract or extend, causing the clamping plate 4 to rotate in the forward or reverse direction to increase or decrease the contact force between the drawing wheel 6 and the metal surface, keeping the contact force stable and thus ensuring the quality of the wire drawing. During the wire drawing process, dust and other impurities are generated. Therefore, a protective cover 42 is provided on the clamping plate 4, and the first belt pulley 7, the second belt pulley 7, and the belt 7 are all placed inside the protective cover 42 to avoid the influence of dust and other impurities on the transmission.

[0027] Additionally, it should be noted that the wire drawing wheel 6 can be replaced with a grinding wheel or polishing wheel, etc., for grinding or polishing metal or other materials. Its execution and control process is consistent with the wire drawing process, and will not be described in detail in this embodiment.

[0028] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and therefore, all changes falling within the meaning and scope of the equivalents of the claims are intended to be included within this utility model.
