Description

Technical Field

[0001] This utility model belongs to the field of impeller shaft processing technology, specifically a polishing device for the inner wall of an impeller shaft hole. Background Technology

[0002] As a core component of fluid machinery such as water pumps and compressors, the manufacturing and assembly precision of the impeller directly determines the performance, efficiency and service life of the whole machine. Among them, the impeller shaft hole is a key part that fits with the drive shaft, and the surface processing quality of the inner wall of the hole is particularly important.

[0003] Traditional polishing equipment mostly uses fixed polishing dimensions and has a fixed operating range, which is not convenient for meeting the polishing needs of different inner wall sizes. In addition, the metal debris generated during polishing adheres to the inside of the impeller shaft and needs to be transferred to the next process for cleaning, which is very cumbersome and affects production efficiency.

[0006] Preferably, an n-shaped plate is fixedly installed on one side of the top surface of the support platform, a cylinder is fixedly installed at the top of the n-shaped plate, a push column is fixedly installed at the output end of the cylinder, an elastic expansion cover is fixedly installed on the outside of the push column, one end of the push column is fixedly installed to a fixing block, a second telescopic rod is fixedly installed on the outside of the fixing block, a fixing plate is fixedly installed at the output end of the second telescopic rod, a motor is fixedly installed on the outside of the fixing plate, and a polishing roller is fixedly installed at the drive end of the motor.

[0007] Preferably, the lower positioning seat has symmetrically distributed magnetic suction ports at one end, and magnetic suction blocks are slidably installed inside each of the two magnetic suction ports. A movable box is fixedly installed at one end of each of the two magnetic suction blocks. A magnetic suction frame is fixedly installed inside the movable box, and an adjusting ring is fixedly installed outside the movable box.

One end of each thrust spring is fixedly connected to the two fixing rings, and the other end of each thrust spring is fixedly connected to the two limiting rods.

[0008] Compared with the prior art, the beneficial effects of this utility model are: 1. The cylinder pushes the push column, which in turn moves the fixed block and the second telescopic rod. The second telescopic rod then moves the fixed plate and the motor. The motor drives the polishing roller into the inner wall of the impeller body, where it rotates to perform polishing. The second telescopic rod pushes and pulls the fixed plate to extend and retract, facilitating the polishing of inner walls of different sizes. The push column also drives the elastic expansion cover into the impeller body, allowing waste to be concentrated and discharged from one of the outlets of the impeller body. A magnetic frame is used to collect the metal debris pushed out by the elastic expansion cover. This system is convenient for polishing different inner wall sizes and for handling metal debris, making it very practical and efficient, thus improving production efficiency. 2. The impeller body is limited by a limit rod, and the fixed ring is pulled by a thrust spring. The sliding column slides on the limit rod to push the impeller body to move, thereby facilitating the unloading and unloading of materials from the impeller body. Attached Figure Description

[0013] The impeller body 6 is clamped and positioned by pushing the upper positioning seat 5 downward through the first telescopic rod 4 to connect with the lower positioning seat 2.

[0014] An n-shaped plate 7 is fixedly installed on one side of the top surface of the support platform 1. A cylinder 8 is fixedly installed on the top of the n-shaped plate 7. A push column 9 is fixedly installed at the output end of the cylinder 8. An elastic expansion cover 10 is fixedly installed on the outside of the push column 9.

A polishing roller 15 is fixedly installed at the drive end of the motor 14.

[0015] The cylinder 8 pushes the push column 9 to move, which in turn moves the fixed block 11 and the second telescopic rod 12. The second telescopic rod 12 moves the fixed plate 13 and the motor 14. The motor 14 drives the polishing roller 15 into the inner wall of the impeller body 6. The motor 14 rotates the polishing roller 15 to perform polishing. The second telescopic rod 12 pushes and pulls the fixed plate 13 to extend and retract, which facilitates the polishing of inner walls of different sizes. The push column 9 drives the elastic expansion cover 10 into the impeller body 6, which facilitates the centralized pushing of waste material out of one of the outlets of the impeller body 6.

[0016] The lower positioning base 2 has symmetrically distributed magnetic suction ports 16 at one end. Magnetic suction blocks 17 are slidably installed inside each of the two magnetic suction ports 16. Movable boxes 18 are fixedly installed at one end of each of the two magnetic suction blocks 17. Magnetic frames 19 are fixedly installed inside the movable boxes 18. Adjustment rings 20 are fixedly installed outside the movable boxes 18.

[0017] The magnetic block 17 is inserted into the magnetic port 16 to help position and support the movable box 18. Then, the magnetic frame 19 inside the movable box 18 is used to easily adsorb and collect the metal debris pushed out by the elastic expansion cover 10 after the impeller body 6 is polished, so as to facilitate the centralized treatment of polishing debris waste.

[0018] Limiting rods 21 are fixedly installed on the outer side of both the lower positioning seat 2 and the upper positioning seat 5. Sliding columns 22 are slidably installed inside both limiting rods 21. A fixing ring 23 is fixedly installed at one end of both sliding columns 22.

[0019] The impeller body 6 is limited by the limiting rod 21, and the fixed ring 23 is pulled by the thrust spring 24. The sliding column 22 slides on the limiting rod 21 to push the impeller body 6 to move, thereby facilitating the unloading and unloading of materials from the impeller body 6.

[0020] Working principle: The impeller body 6 is placed on the lower positioning seat 2. The upper positioning seat 5 is moved down by the first telescopic rod 4 to align with the lower positioning seat 2 and clamp the impeller body 6. Then, the cylinder 8 pushes the push column 9 to move. The push column 9 moves the fixed block 11 and the second telescopic rod 12. The second telescopic rod 12 moves the fixed plate 13 and the motor 14. The motor 14 drives the polishing roller 15 into the inner wall of the impeller body 6. The motor 14 rotates the polishing roller 15 to perform polishing. The second telescopic rod 12 pushes and pulls the fixed plate 13 to extend and retract, which facilitates the polishing of inner walls of different sizes. The push column 9 drives the elastic expansion cover 10 into the impeller body 6, so as to facilitate the centralized pushing of waste material out of one of the ports of the impeller body 6. Then, the magnetic frame 19 inside the movable box 18 is used to conveniently adsorb and collect the metal debris pushed out by the elastic expansion cover 10 after the impeller body 6 is polished, so as to facilitate the centralized processing of polishing debris waste. The limit rod 21 helps to limit the impeller body 6, and the thrust spring 24 pulls the fixed ring 23 to slide. The sliding column 22 slides on the limit rod 21 to push the impeller body 6 to move, thereby facilitating the unloading and picking of material from the impeller body 6.
