Description

Technical Field

[0001] This utility model relates to the field of worm gear grinding technology, and more specifically, to worm gear grinding equipment. Background Technology

[0002] In the current industrial manufacturing field, the grinding process of worm gears places high demands on the precision and flexibility of equipment. Traditional worm gear grinding equipment often lacks a flexible adjustment mechanism in actual use, making it impossible to precisely adjust the grinding force according to the different materials, sizes, and surface requirements of the worm gears. This limitation means that operators often need to manually adjust or replace equipment parts when faced with diverse worm gear grinding needs, increasing the complexity and time cost of operation. In addition, a fixed grinding force may cause excessive wear or insufficient grinding of the worm gear surface, affecting the final quality of the product.

[0003] The inconvenience of adjusting existing equipment not only reduces production efficiency but also limits the scope of application. In actual production, different worm gears may require different grinding forces to achieve the best surface finish and precision requirements. However, due to the limitations of the equipment design, it is difficult for operators to adjust the grinding force quickly and accurately, which greatly reduces the ease of use of the equipment.

[0014] Compared with the prior art, the present invention provides a worm gear grinding device, which has the following beneficial effects:

[0015] 1. The adjustment mechanism achieves uniform grinding pressure distribution through multiple expansion springs equidistantly installed on the inner wall of the sleeve. The bevel and rounded corners on the grinding block ensure a close fit with the worm gear surface. The sliding fit between the positioning sleeve and the insertion rod provides flexible force adjustment capability. The setting of multiple positioning sleeves allows the expansion springs to be fixed in different positions, thereby achieving precise control of grinding force. This multi-adjustment mechanism significantly improves the accuracy and adaptability of the grinding process.

[0016] 2. The fixing mechanism achieves a stable clamping effect through the fit design of the fixing sleeve and the sleeve, combined with the threaded connection of the limiting sleeve. The even distribution of multiple insertion rods ensures the balance of fixing force, and the coaxial structural design further enhances the stability of fixing. This reliable fixing system provides a stable working foundation for the grinding process.

[0017] 3. The moving mechanism achieves smooth linear motion through the precise cooperation of the slide rail and the slider. The rotating connection between the receiving sleeve on the moving seat and the drive shaft ensures the stability of the rotational motion. The motor drives the drive shaft to rotate through the belt drive system, realizing the smooth transmission of power. This motion control improves the efficiency and quality of grinding.

[0027] Please see Figure 1-5The worm gear grinding equipment includes a base plate 1, which is mounted on an external device. An adjustment mechanism is installed on the base plate 1, comprising a moving mechanism, a sleeve 2, an expansion spring 3, a grinding block 4, a positioning sleeve 5, an insertion rod 6, and a fixing mechanism. The moving mechanism is connected to the base plate 1 and the sleeve 2. Multiple expansion springs 3 are provided, and are equidistantly installed on the inner wall of the sleeve 2. A grinding block 4 is installed on the other end of each expansion spring 3. Each grinding block 4 has a bevel 7 and a rounded corner 8. The multiple grinding blocks 4 are respectively attached to the worm gear. A positioning sleeve 5 is installed on the expansion spring 3, and an insertion rod 6 is slidably connected inside the positioning sleeve 5. The fixing mechanism is installed inside the sleeve 2. Multiple positioning sleeves 5 are provided, and two positioning sleeves 5 are provided on each expansion spring 3. Each positioning sleeve 5 has an expansion spring 7 and a rounded corner 8. The fixing mechanism includes a fixing sleeve 10, multiple insertion rods 6 are provided, and the multiple insertion rods 6 are respectively installed on the fixing sleeve 10. The fixing sleeve 10 fits against the sleeve 2, and the sleeve 2 is threaded with a limiting sleeve 11, which presses against the fixing sleeve 10. The limiting sleeve 11, the fixing sleeve 10 and the sleeve 2 are coaxially arranged. The moving mechanism includes a slide rail 12, a slider 13 and a moving seat 14. The slide rail 12 is installed on the base plate 1. The lower end of the moving seat 14 is equipped with a slider 13, which is slidably connected to the slide rail 12. A receiving sleeve 15 is fixedly provided on the moving seat 14. A transmission shaft 16 is rotatably provided inside the receiving sleeve 15. The sleeve 2 is installed on the transmission shaft 16. A motor 17 is fixedly provided on the moving seat 14. The extended end of the motor 17 is connected to a belt 18, which meshes with the transmission shaft 16.

[0028] In this embodiment, when grinding the worm gear with different forces, the insertion rods 6 at different positions are first inserted into the positioning sleeves 5, and then the fixing sleeve 10 is pressed onto the sleeve 2. Since the limiting sleeve 11 is threaded onto the sleeve 2, the limiting sleeve 11 is pressed onto the fixing sleeve 10 and kept in a fixed state. Since the insertion rods 6 are inserted into the positioning sleeves 5 at different positions, the expansion spring 3 can be fixed at different positions. When the positioning sleeve 5 is fixed close to the grinding block 4, the grinding force is greater. When it is fixed away from the grinding block 4, the grinding force is smaller, thus completing the adjustment process. More specifically, when grinding the worm gear, one end of the worm gear is first fixed, and then the other end is inserted into the sleeve 2. The motor 17 is started, which can drive the transmission shaft 16 and the sleeve 2 to rotate. Therefore, the grinding block 4 can be driven to grind the worm gear. And through the cooperation of the slider 13 and the slide rail 12, different positions can be ground, thus completing the grinding process.

[0029] In summary, when using or operating the entire equipment: when grinding the worm gear with different forces, firstly, the insertion rods 6 at different positions are inserted into the positioning sleeves 5 respectively, and then the fixing sleeve 10 is pressed onto the sleeve 2. Since the limiting sleeve 11 is threaded onto the sleeve 2, the limiting sleeve 11 is pressed onto the fixing sleeve 10 and kept in a fixed state. Since the insertion rods 6 are inserted into the positioning sleeves 5 at different positions, the expansion spring 3 can be fixed at different positions. When the positioning sleeve 5 is fixed close to the grinding block 4, the grinding force is greater, and when it is fixed away from the grinding block 4, the grinding force is smaller, thus completing the adjustment process.

[0030] When grinding the worm, first fix one end of the worm, then insert the other end into the sleeve 2. Start the motor 17, which will drive the transmission shaft 16 and the sleeve 2 to rotate. This will drive the grinding block 4 to grind the worm. Through the cooperation of the slider 13 and the slide rail 12, different positions can be ground, thus completing the grinding process.

[0031] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
