Description

Technical Field

[0001] The utility model relates to the field of spring grinding machines, in particular to a grinding wheel mechanism of a spring grinding machine. Background Art

[0002] In the spring manufacturing industry, spring grinding machines are one of the key equipment, and their performance directly affects the production efficiency and quality of springs. Traditional spring grinding machine designs often focus on grinding one end of a spring at a time. Although this working method can complete basic grinding tasks, its limitations gradually become apparent when facing the needs of large-scale and high-efficiency production. Specifically, because traditional spring grinding machines can only grind one end of a spring, completing the full grinding of a spring (i.e., grinding both ends) requires two independent operations, which not only increases the operator's workload but also significantly reduces overall production efficiency.

[0003] In addition, multiple clamping and positioning processes may also cause the dimensional deviation of the spring to increase, affecting the consistency of the product; at the same time, frequent equipment start and stop also aggravates the wear of mechanical parts, shortens the service life of the equipment, and increases maintenance costs.

[0004] Therefore, it is necessary to provide a new grinding wheel mechanism of a spring grinding machine to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a grinding wheel mechanism of a spring grinding machine.

[0012] Preferably, a slide rail is installed on the top of the base, and the movable plate is slidably connected to the slide rail.

[0013] Compared with the related art, the grinding wheel mechanism of the spring grinding machine provided by the present invention has the following beneficial effects:

[0014] Improve production efficiency: By achieving synchronous or continuous grinding of both ends of the spring, the number of grinding times and clamping and positioning time are reduced, significantly improving production efficiency; operators can complete comprehensive grinding without having to adjust the spring position multiple times, greatly shortening the production cycle;

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0023] See also Figure 1-3 The top of the movable plate 5 is connected to the movable plate 6 by the movable plate 7 and the movable plate 8 is connected to the movable plate 9 by the movable plate 8.

[0024] See also Figure 2-3 The inner wall of the slide groove 2 is rotatably connected to the first threaded rod 12, and the two connecting seats 3 are threadedly connected to the first threaded rod 12. A connecting groove 13 is provided at the top of the movable plate 5, and the inner wall of the connecting groove 13 is rotatably connected to the second threaded rod 14. The two baffles 6 are threadedly connected to the second threaded rod 14, and a scale line 15 is provided at the top of the movable plate 5. One end of the second threaded rod 14 extends out of the movable plate 5 and is provided with an inner hexagonal groove 16. The two ends of the pressure plate 8 are symmetrically fixed with rubber pads 17. The first threaded rod 12 and the second threaded rod 14 are both bidirectional threaded rods, and a drive motor is installed at one end of the first threaded rod 12 and the bottom end of the turntable 10.

[0025] The working principle of the grinding wheel mechanism of the spring grinding machine provided by the utility model is as follows:

[0026] Adjustment and positioning of the grinding wheel 4: First, by rotating the first threaded rod 12 installed on the inner wall of the slide groove 2 of the base 1, the two connecting seats 3 are driven to slide symmetrically in the slide groove 2 using the principle of threaded connection, thereby adjusting the position of the grinding wheel 4 to adapt to springs of different lengths and specifications; the grinding wheel 4 is installed inside the connecting seat 3 and can rotate freely for grinding operations;

[0027] Spring fixing and pressing: The spring to be polished is placed in an appropriate position on the movable plate 5; then, by controlling the operation of the electric push rod 7, the pressing plate 8 moves downward and presses the spring; rubber pads 17 are fixed at both ends of the pressing plate 8 to reduce damage to the spring surface and increase stability;

[0028] Adjustment and positioning of baffle 6: In order to fix the position of the spring during the grinding process and prevent it from shifting or jumping, the position of baffle 6 needs to be adjusted. By rotating the second threaded rod 14 at the top of the movable plate 5, the two baffles 6 are driven to move in symmetrical directions using the principle of threaded connection until they are close to the side of the spring, thereby achieving a stable clamping of the spring.

[0029] Synchronous grinding operation: After the grinding wheel 4 and the baffle 6 are adjusted into place, the drive motor is started to make the first threaded rod 12 and the turntable 10 work simultaneously; the first threaded rod 12 continues to keep the grinding wheel 4 in the appropriate position, while the turntable 10 drives the movable plate 5 to slide longitudinally along the slide rail 18 of the base 1 through the pull rod 11; thus, as the movable plate 5 moves, the grinding wheel 4 can continuously grind along the length direction of the spring, achieving a seamless transition from one end to the other; since the grinding wheel 4 is designed to have a symmetrical structure, it can grind both ends of the spring simultaneously or separately, greatly improving the grinding efficiency;

[0030] Automated control and safety protection: The entire grinding process is automatically controlled by the controller, including the adjustment of the grinding wheel 4 and the baffle 6, the sliding of the movable plate 5, and the lifting and lowering of the electric push rod 7. In addition, to ensure the safety of the operator, the grinding wheel 4 mechanism is also equipped with safety protection devices such as a protective cover and an emergency stop switch. In the event of an abnormal situation, the operator can quickly press the emergency stop switch to stop all moving parts, ensuring the safety of both personnel and equipment.

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
