Description

Technical Field

[0001] The utility model belongs to the technical field of wire drawing machine equipment, and particularly relates to a handheld wire drawing machine quick-disassembly tooling. Background Art

[0002] A handheld wire drawing machine, also known as a grinder, is a tool used for metal surface treatment, primarily for polishing, grinding, and texturing. It uses a rotary motion to remove oxide layers and burrs from the metal surface, or to perform decorative treatments, giving the metal surface a smooth or textured finish.

[0003] When the current wire drawing machine is in use, the wire drawing wheel is greatly worn out during long-term use and is a wearing part that needs to be replaced. The existing replacement method requires the use of tools such as screwdrivers to completely remove the wire drawing wheel and surrounding locking parts, which not only has low replacement efficiency but is also inconvenient to use.

[0027] The following is a combination of the appended examples of the present invention Figure 1-Figure 3 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. The specific embodiments described here are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0028] Example:

[0029] The materials prepared in this example are as follows:

[0030] 1. Prepare a wire drawing machine body 1;

[0031] 2. Prepare a mounting shaft 2;

[0032] 3. Prepare a drawing wheel 3;

[0033] 4. Prepare an adjustment knob 41;

[0034] 5. Prepare a pressing plate 42;

[0035] 6. Prepare a step screw 43;

[0036] 7. Prepare an adjustment spring 44;

[0037] 8. Prepare two limit columns 22;

[0038] 9. Prepare two flat keys 23.

[0039] like Figure 1-Figure 3 As shown, this embodiment provides a handheld wire drawing machine quick-disassembly tooling, and the processing process is as follows:

[0040] A threaded hole 21 is provided in the middle of one end of the mounting shaft 2, and two limiting posts 22 are installed outside the threaded hole 21. Mounting grooves are provided on both sides of the mounting shaft 2, and two flat keys 23 are installed inside the mounting grooves.

[0041] A through hole is formed in the middle of the drawing wheel 3, and four grooves 31 are formed evenly along the circumference of the through hole of the drawing wheel 3.

[0042] A through hole is provided in the middle of the pressure plate 42, and four pressure blocks 421 are evenly extended along its circumference on the outside. The shape and position of the pressure blocks 421 are the same as those of the groove 31, and a group of symmetrically arranged guide grooves 422 are provided on one side of the pressure plate 42, and a group of symmetrically arranged limiting grooves 423 are provided on the other side. The limiting grooves 423 and the guide grooves 422 are both arc-shaped, and the angle of the limiting grooves 423 is 60°.

[0043] A through hole is formed in the middle of the adjusting knob 41 , and an arc-shaped spiral surface 411 extends from the bottom.

[0044] During assembly, one end of the mounting shaft 2 with the mounting limit column 22 is fixedly installed on one end of the wire drawing machine body 1, and then the through hole of the wire drawing wheel 3 is sleeved on the outside of the mounting shaft 2, and then the outside of the step screw 43 is sleeved with the adjusting knob 41, the pressure plate 42 and the adjusting spring 44 from top to bottom. The step screw 43, the adjusting knob 41, the pressure plate 42 and the adjusting spring 44 constitute a quick-release assembly 4, the adjusting knob 41 is in contact with the pressure plate 42, and the pressure plate 42 is in contact with the adjusting spring 44, and then the step screw 43 is installed inside the threaded hole 21. At this time, the limit groove 423 is connected to the limit column 22, the guide groove 422 is connected to the spiral surface 411, and the pressure block 421 is misaligned with the groove 31. At this time, the adjusting spring 44 presses the pressure plate 42 and the adjusting knob 41 tightly to fix them.

[0045] When replacing, turn the adjusting knob 41. As the adjusting knob 41 is turned, the spiral surface 411 rotates along the guide groove 422, bringing the adjusting knob 41 and the pressure plate 42 into contact with the locking state. At this time, the adjusting spring 44 is in a compressed state, and then the pressure plate 42 is turned to adjust the pressure block 421 and the groove 31 to an overlapping state. Then, the drawing wheel 3 is removed from the surface of the mounting shaft 2, and the new drawing wheel 3 is inserted into the outside of the mounting shaft 2. After the replacement is completed, turn the adjusting knob 41 again, and the guide groove 422 is located at the lowest end of the spiral surface 411. At this time, continue to turn the adjusting knob 41, and the highest end of the spiral surface 411 drives the pressure plate 42 to continue rotating along the guide groove 422 until the pressure block 421 is completely staggered with the groove 31. The limit groove 423 at the bottom of the pressure plate 42 cooperates with the limit column 22 to prevent the pressure plate 42 from moving too much. After the adjustment is completed, use the adjusting spring 44 to lock and fix it.

[0046] In summary, the present tool can replace the drawing wheel 3 without the aid of tools, which is not only convenient to use but also has a high connection stability after replacement.

[0047] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
