Abstract
Description
Technical Field
[0001] This utility model relates to the field of helical gear grinding and polishing technology, specifically to a helical gear grinding and polishing device. Background Technology
[0002] As a special type of gear, helical gears have strict precision requirements for tooth profile and surface finish. In particular, the machining of helical gears has even more stringent requirements for the tooth profile and surface finish. Compared with spur gears, helical gears have better transmission smoothness and noise control, so they are widely used in high-speed and heavy-load applications, such as helical gear reducers.
[0003] Most helical gear grinding and polishing devices on the market currently use mechanical grinding, which does not achieve ideal results. Furthermore, mechanical grinding generally requires manual operation, which is very cumbersome. In addition, the intervention of manual operation limits the processing speed and cannot meet the needs of large-scale grinding. Therefore, a helical gear grinding and polishing device is proposed to address the above problems. Summary of the Invention
[0004] The purpose of this invention is to provide a helical gear grinding and polishing device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:

A base is fixedly connected to the bottom of the housing, and a cylinder is fixedly connected to the top of the housing. One end of the cylinder passes through the second storage tank and is fixedly connected to a second piston. A set of connecting rods is fixedly connected to one side of the second piston, and a first piston is fixedly connected to the other end of the connecting rods. The outer sides of the first and second pistons are slidably connected to the first and second storage tanks, respectively. One side of each of the first and second storage tanks is fixedly connected to the housing. Two telescopic tubes are installed on the outer side of the connecting rods.

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this utility model, by setting up a first storage tank and a second storage tank, which are filled with abrasive media, the abrasive flow processing technology can be used to grind the helical gear evenly and efficiently.

[0022] Please see Figure 1-3 This utility model provides a technical solution:
[0023] A helical gear grinding and polishing device includes a housing 2, a first storage tank 3, a second storage tank 4, and a grinding chamber 10. A base 1 is fixedly connected to the bottom end of the housing 2, and a cylinder 8 is fixedly connected to the top end of the housing 2. One end of the cylinder 8 passes through the second storage tank 4 and is fixedly connected to a second piston 16. A set of connecting rods 6 is fixedly connected to one side of the second piston 16, and a first piston 5 is fixedly connected to the other end of the connecting rods 6. The outer sides of the first piston 5 and the second piston 16 are slidably connected to the first storage tank 3 and the second storage tank 4, respectively. One side of the first storage tank 3 and the second storage tank 4 are both fixedly connected to the housing 2. Two telescopic tubes 7 are installed on the outer side of the connecting rods 6. The first storage tank 3 and the second storage tank 4 are both provided with a discharge port 9. The grinding chamber 10 is fixedly connected to the middle position of the first storage tank 3 and the second storage tank 4. A sliding door 14 is installed on the front side of the grinding chamber 10, and a handle 15 is fixedly connected to the front side of the sliding door 14.
[0024] The single connecting rod 6 has two telescopic tubes 7. The top inner wall of the first storage tank 3 is fixedly connected to the telescopic tube 7, and the other end of the telescopic tube 7 inside the first storage tank 3 is fixedly connected to the first piston 5 to prevent the abrasive medium from leaking out of the first storage tank 3. The bottom inner wall of the second storage tank 4 is fixedly connected to the telescopic tube 7, and the other end of the telescopic tube 7 inside the second storage tank 4 is fixedly connected to the second piston 16 to prevent the abrasive medium from leaking out of the second storage tank 4. The left and right sides of the grinding chamber 10 are provided with through holes. Bolts 12 are installed on the through holes of the grinding chamber 10. Nuts 13 are screwed to both ends of the bolts 12 to make the bolts 12 firmly fixed. The bolts 12 pass through the helical gear 11. The helical gear 11 is detachably connected to the grinding chamber 10 through the bolts 12. The bolts 12 can fix the helical gear 11 on the grinding chamber 10.
[0025] Workflow: All electrical appliances in this utility model are equipped with an external power supply or a built-in battery. First, ensure that the base 1 is placed stably on a flat ground. Check whether all components inside the housing 2 are intact. Confirm whether the connection between the cylinder 8 and the second piston 16 is firm, and whether the connection between the connecting rod 6 and the first piston 5 and the second piston 16 is normal. Load an appropriate amount of abrasive medium into the first storage tank 3 through the discharge port 9, ensuring that the quality and specifications of the abrasive medium meet the requirements for grinding and polishing the helical gear 11. The operator opens the sliding door 14 through the handle 15, places the helical gear 11 into the grinding chamber 10, and fixes it to the grinding chamber 10 with bolts 12 and nuts 13. Start the cylinder 8, and the reciprocating motion of the cylinder 8... The first piston 5 and the second piston 16 are driven to reciprocate. The reciprocating motion of the first piston 5 and the second piston 16 is transmitted through the connecting rod 6. The telescopic tube 7 ensures that the abrasive medium does not leak. The first piston 5 and the second piston 16 push the abrasive medium out of the first storage tank 3 and the second storage tank 4 and into the grinding chamber 10 through the discharge port 9. The abrasive medium moves back and forth between the first storage tank 3 and the second storage tank 4 to achieve continuous grinding of the helical gear 11. The abrasive medium grinds the surface of the helical gear 11 evenly, especially the hard-to-reach parts such as the tooth root of the helical gear 11. After grinding is completed, the cylinder 8 is closed to stop the reciprocating motion of the cylinder 8. The first piston 5 and the second piston 16 stop pushing the abrasive medium. The residual abrasive on the surface of the helical gear 11 is cleaned, and the helical gear 11 is taken out for subsequent processing. The abrasive medium in the first storage tank 3 and the second storage tank 4 is cleaned, and the device is maintained and serviced as necessary. Through the above workflow, the helical gear grinding and polishing device of this utility model can achieve automated and efficient helical gear grinding and polishing, significantly improving production efficiency and processing quality.
