[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model embodiment provides a drive disc dresser, which is installed on a grinding machine. The grinding machine has a drive disc and includes a dressing mechanism 1, a spindle 2, a sleeve 3, a position adjustment mechanism 4, and a connecting rod 5.

[0042] The dressing mechanism 1 is used to dress the surface of the drive disc. A spindle 2 is mounted on the equipment; the spindle 2 is flush with the surface of the drive disc, laying the foundation for subsequent dressing operations. A sleeve 3 is fitted around the outer circumference of the spindle 2; a position adjustment mechanism 4 is used for fine adjustment of the relative position of the sleeve 3 and the spindle 2 along their axial direction; a connecting rod 5 is connected at one end to the sleeve 3 and at the other end to the dressing mechanism 1, and the dressing mechanism 1 can move closer to or further away from the surface of the drive disc.

[0043] The drive disc dresser provided by this utility model, in use, firstly, sets the main shaft 2 on the equipment, with the main shaft 2 flush with the drive disc surface. Then, the operator rotates the connecting rod 5 to the corresponding position of the drive disc according to the specific grinding position of the drive disc, bringing one end of the dressing mechanism 1 close to the drive disc surface. At this point, the position adjustment mechanism 4 is used to adjust the relative position of the sleeve 3 and the main shaft 2 along their axial direction, achieving fine-tuning of the dressing mechanism's position to meet the dressing requirements. Through this precise fine-tuning operation, accurate control of the position of the dressing mechanism 1 can be achieved, thus meeting drive disc dressing tasks with different precision requirements, ensuring that the drive disc can be put into use in optimal condition after dressing, and improving the overall stability and reliability of the equipment operation.

[0044] To further optimize the above technical solution, the position adjustment mechanism 4 includes a manual adjustment part 41, a spindle cover 42, and an elastic element 43. The manual adjustment part 41 is threaded to the outer periphery of the spindle 2, and the top end of the manual adjustment part 41 contacts the sleeve 3, which can convert rotational motion into linear motion. By rotating the manual adjustment part 41, since the thread pitch is fixed, the manual adjustment part 41 will move a fixed distance along the axis of the spindle 2 for each rotation of a certain angle, so that the operator can make fine adjustments to the relative position of the sleeve 3 and the spindle 2 along their axis according to the actual trimming needs.

[0045] The spindle cover 42 includes a first horizontal portion 421 and a first vertical portion 422. The first horizontal portion 421 is vertically sleeved on the outer wall of the spindle 2. The first vertical portion 422 is vertically connected to the first horizontal portion 421, forming a stable frame structure and enhancing the structural stability of the entire position adjustment mechanism 4. The first vertical portion 422 is slidably connected to the outer wall of the sleeve 3, providing precise guidance for the movement of the sleeve 3 along the axis of the spindle 2. There is a gap between the first vertical portion 422 and the spindle 2.

[0046] The elastic element 43 is disposed within the gap, with one end of the elastic element 43 abutting against the first horizontal portion 421 and the other end abutting against the top of the sleeve 3. When the equipment vibrates, the elastic element 43 can absorb and buffer this vibration energy, reducing the impact of vibration on the sleeve 3 and the dressing mechanism 1, thereby ensuring the stability and quality of the dressing process. For example, when the drive disc rotates at high speed for dressing, the equipment may generate a certain amount of vibration. The elastic element 43 can effectively reduce the interference of this vibration on the dressing mechanism 1, making the dressing smoother and more precise.

[0047] Therefore, through the coordinated operation of the manual adjustment part 41, the spindle cover 42 and the elastic element 43, the position adjustment mechanism 4 ensures that the operator will not feel too stiff or difficult when rotating the manual adjustment part 41, thus improving the comfort and convenience of operation, and ensuring the relative fixation of the sleeve 3 in the axial direction.

[0048] To further optimize the above technical solution, the cross-section of the spindle cover 42 is stepped, so that when it is subjected to external force, the force can be more evenly distributed to various parts. The spindle cover 42 also includes a second vertical part 423 and a second horizontal part 424. The second vertical part 423 is perpendicularly connected to the first horizontal part 421, and there is a gap between the second vertical part 423 and the spindle 2. One end of the second horizontal part 424 is perpendicularly connected to the second vertical part 423, and the other end is perpendicularly connected to the first vertical part 422, and there is a gap between the second horizontal part 424 and the spindle 2.

[0049] When the equipment vibrates during operation or is subjected to external forces during position adjustment, the second vertical part 423 and the second horizontal part 424 share the load together with the original first horizontal part 421 and the first vertical part 422. Compared with a single-structure spindle cover 42, this stepped structure can avoid local stress concentration, reduce the risk of component damage caused by stress concentration, and thus improve the service life of the entire spindle cover 42 and the position adjustment mechanism 4.

[0050] Furthermore, the second vertical portion 423 and the second horizontal portion 424 are interconnected with the first horizontal portion 421 and the first vertical portion 422, forming a more stable structure. This structure can better limit the movement trajectory of the sleeve 3, preventing unnecessary swaying or deviation when it moves along the axis of the main shaft 2. It provides more reliable guidance and support for the sleeve 3, ensuring that the sleeve 3 can move accurately to the designated position, thereby guaranteeing the position adjustment accuracy of the dressing mechanism 1.

[0051] To further optimize the above technical solution, at the maximum compression of the elastic element 43, the outer side of the elastic element 43 contacts the inner side of the second vertical part 423. A clear limit is set for the compression of the elastic element 43, thereby limiting the range of movement of the sleeve 3 along the axis of the main shaft 2. This prevents the sleeve 3 and the dressing mechanism 1 from exceeding their reasonable working positions due to over-adjustment, avoiding adverse effects on the dressing of the drive disc and ensuring the accuracy and safety of the dressing work. By limiting the maximum compression of the elastic element 43, the position of the dressing mechanism 1 during fine-tuning is made more precise and controllable. Each adjustment is performed within a reasonable range, preventing dressing position deviations caused by excessive compression or stretching of the elastic element 43, thus improving the dressing accuracy of the drive disc.

[0052] To further optimize the above technical solution, the dressing mechanism 1 includes a housing 11, a drive component 12, and a grinding wheel assembly 13. The housing 11 is connected to the connecting rod 5; the drive component 12 is disposed inside the housing 11; the grinding wheel assembly 13 is connected to the drive component 12 and is used to dress the surface of the drive disc. The drive component 12 is the power source of the dressing mechanism 1, providing stable and continuous power to the grinding wheel assembly 13, enabling it to dress the surface of the drive disc at a suitable speed and torque. The grinding wheel assembly 13 can directly act on the surface of the drive disc to achieve the dressing function.

[0053] To further optimize the above technical solution, the grinding wheel assembly 13 includes a grinding wheel base 131, a grinding wheel 132, and a grinding wheel locking block 133. The grinding wheel base 131 is connected to the drive component 12; the grinding wheel 132 is fixed to the end of the grinding wheel base 131 away from the drive component 12; the grinding wheel locking block 133 is used to lock the grinding wheel base 131 and the grinding wheel 132. The grinding wheel base 131 acts as a connecting bridge between the drive component 12 and the grinding wheel 132, and can stably and efficiently transmit the power generated by the drive component 12 to the grinding wheel 132, ensuring that the grinding wheel 132 dresses the drive disc at a suitable speed and torque. The function of the grinding wheel locking block 133 is to lock the grinding wheel base 131 and the grinding wheel 132. When the grinding wheel 132 rotates at high speed for dressing operations, it will generate a large centrifugal force and vibration. The grinding wheel locking block 133 can accurately ensure that the grinding wheel 132 is always firmly fixed on the grinding wheel base 131 during high-speed rotation, ensuring the safe and stable operation of the dressing work.

[0054] To further optimize the above technical solution, the grinding wheel assembly 13 also includes a tensioning sleeve 134, disposed between the grinding wheel base 131 and the output shaft of the drive component 12. The elastic deformation of the tensioning sleeve 134 generates radial force, ensuring a clearance-free fit between the grinding wheel base 131 and the output shaft. This guarantees that the torque output by the drive component 12 can be efficiently and stably transmitted to the grinding wheel base 131, thereby driving the grinding wheel 132 to rotate for dressing operations. Compared to traditional connection methods, this reduces power transmission losses, improves energy utilization efficiency, allows the grinding wheel to operate at a more stable speed, and enhances the dressing effect.

[0055] The protective cover 135 is located outside the grinding wheel 132 and is connected to the housing 11. The protective cover 135 can protect the grinding wheel 132.

[0056] To further optimize the above technical solution, the driving component 12 is a pneumatic motor or an electric motor, used to drive the rotation of the grinding wheel 132 to grind the drive disc.

[0057] Therefore, the drive disc dresser provided by this utility model can perform end face grinding on the drive disc of a grinding machine, thereby improving the precision and requirements of the product.
