Description

Technical Field

[0001] The utility model relates to the field of machining, in particular to a diameter-changing device for heat treatment of metal parts based on machining. Background Technique

[0002] Mechanical parts, also known as mechanical elements, are the basic elements that make up a machine. They are individual fabricated parts that are inseparable from the machine and the equipment. Since the emergence of machinery, there have been corresponding mechanical parts. However, as a discipline, mechanical parts have been separated from mechanical construction and mechanics. With the development of the mechanical industry, the emergence of new design theories and methods, new materials, and new processes, mechanical parts have entered a new stage of development. Theories such as the finite element method, fracture mechanics, elastohydrodynamic lubrication, optimization design, reliability design, computer-aided design, solid modeling, system analysis, and design methodology have gradually been used in the research and design of mechanical parts.

[0003] The Chinese patent discloses a diameter-changing device for heat treatment of metal parts based on machining (authorization announcement number CN113334167 A). This patented technology can accurately measure the required diameter range during the process of expanding and changing the diameter, saving the time of secondary surveying. However, when the user rotates the handwheel by hand to drive the lifting block to slide, the user's hand needs to move along with the sliding of the lifting block. In this way, the user needs to rotate the handwheel while following the movement of the handwheel, which is not convenient. At the same time, after adjusting the distance of the grinding mechanism, the hand cannot release the handwheel. If the hand releases the handwheel, the lifting block will descend under the influence of gravity. It is very troublesome to fix the position of the transmission rod by rotating the adjusting rod with the other hand without releasing the handwheel with one hand. It is time-consuming and laborious to operate. Therefore, the technical personnel in this field provide a diameter-changing device for heat treatment of metal parts based on machining to solve the problems raised in the above background technique.

[0024] Please refer to Figures 1 to 5, in this embodiment, a variable-diameter device for heat treatment of metal parts based on machining is provided, including a base 1, a vertical rod 3 and a sliding seat 4. The upper end of the base 1 is symmetrically and rotatably connected with a matching rod 2. The vertical rod 3 is installed at the upper end of the base 1, and the vertical rod 3 is a square rod as a whole. The outer surface of the vertical rod 3 is slidably connected with the sliding seat 4. The side surface of the sliding seat 4 is symmetrically and rotatably connected with a support rod 5. One end of the support rod 5 is rotatably connected to one end of the matching rod 2. A grinding mechanism is arranged at the end of the support rod 5 far from the sliding seat 4. The grinding mechanism includes a threaded shaft 6 and a grinding head 11. The threaded shaft 6 is fixedly connected inside the support rod 5. The outer surface of the threaded shaft 6 is rotatably connected with a U-shaped block 7. An anti-slip ring 8 is installed at the rear end of the U-shaped block 7. The outer surface of the threaded shaft 6 is threadedly connected with a nut 9, and the nut 9 is located at the rear side of the U-shaped block 7. An anti-slip ring 10 is installed at the front end of the nut 9. The outer end of the U-shaped block 7 is installed with the grinding head 11. A scale line 12 is installed at the rear end of the vertical rod 3. A pointing block 13 is installed at the upper end of the sliding seat 4, and the pointing block 13 points to the scale line 12. A lifting hole 14 is opened inside the vertical rod 3. A threaded rod 15 is rotatably connected inside the lifting hole 14, and the upper end of the threaded rod 15 passes through the vertical rod 3 and is installed with a rotating block 17. The outer surface of the threaded rod 15 is threadedly connected with a threaded sleeve 16, and the side surface of the threaded sleeve 16 is fixedly connected with the inner wall of the sliding seat 4. A rubber anti-slip annular block 18 is inlaid on the side surface of the rotating block 17. The front and rear ends of the vertical rod 3 are symmetrically installed with extrusion limiting mechanisms 19, and the extrusion limiting mechanisms 19 correspond to the positions of the rubber anti-slip annular blocks 18. The extrusion limiting mechanism 19 includes a fixed block 20 and a blocking mechanism 29. The fixed block 20 is fixedly connected with the vertical rod 3. Symmetrical sliding grooves 21 are opened at the upper end of the fixed block 20. A fixed rod 22 is installed inside the sliding grooves 21. The outer surface of the fixed rod 22 is slidably connected with a slider 23. A first spring 24 is sleeved on the outer surface of the fixed rod 22, and the first spring 24 is located on the side of the slider 23 close to the vertical rod 3. A moving block 25 is slidably connected to the upper end of the fixed block 20, and the lower end of the moving block 25 is fixedly connected with the slider 23. An L-shaped block 26 is installed at the upper end of the moving block 25. One end of the L-shaped block 26 is installed with an arc-shaped block 27, and the arc-shaped block 27 corresponds to the position of the rubber anti-slip annular block 18. A rubber anti-slip block 28 is installed at one end of the arc-shaped block 27 close to the rotating block 17. A blocking mechanism 29 is arranged inside the fixed block 20. The blocking mechanism 29 includes a cavity 30 and a blocking block 33. A matching block 31 is slidably connected inside the cavity 30. Symmetrical second springs 32 are installed at the lower end of the matching block 31. A blocking block 33 is installed at the upper end of the matching block 31, and the blocking block 33 passes through the upper end of the fixed block 20. The end face of the blocking block 33 far from the moving block 25 is an arc surface.

[0025] The working principle of the present utility model is as follows: By driving the threaded rod 15 to rotate through the rotating block 17, the threaded rod 15 and the threaded sleeve 16 cooperate to drive the sliding seat 4 to lift. The sliding seat 4 drives the support rod 5 to lift. Through the matching rod 2, the support rod 5 moves. The support rod 5 drives the grinding mechanism to move, so as to adjust the distance between the two grinding mechanisms. Observing the position where the pointing block 13 moves on the scale line 12 can quickly understand the distance between the two grinding mechanisms.

[0026] Then, push the arc-shaped blocks 27 on both sides to move towards the middle and abut against the rotating block 17, fixing the position of the rotating block 17 so that the threaded rod 15 cannot rotate. At the same time, the friction is increased through the rubber anti-slip annular block 18 and the rubber anti-slip block 28, making the rotating block 17 unable to rotate. When the arc-shaped block 27 moves, it drives the moving block 25 and the slider 23 to move through the L-shaped block 26, compressing the first spring 24. The moving block 25 first contacts the arc surface of the blocking block 33 and pushes the blocking block 33 to descend and retract into the cavity 30. When the arc-shaped block 27 abuts against the rotating block 17, the moving block 25 just moves away from above the blocking block 33, causing the blocking block 33 to lose the limiting force. The matching block 31 and the blocking block 33 are pushed by the second spring 32 to rise and reset and are stuck on the side of the moving block 25, limiting the position of the moving block 25, thereby fixing the position of the arc-shaped block 27;

[0027] Rotate the U-shaped block 7 to drive the grinding head 11 to rotate and adjust the angle. Then, rotate the nut 9 to abut against the U-shaped block 7, fixing the position of the grinding head 11. At the same time, the friction is increased through the first anti-slip ring 8 and the second anti-slip ring 10.

[0028] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments in the present invention without making creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art without special instructions and limitations.
