[0002] Ball mills are important grinding equipment, widely used in many industrial fields such as mining, metallurgy, chemical industry, and building materials. During long-term operation, the mating surfaces of the shaft head with components such as bearings and couplings will gradually wear due to friction. If the coupling is not installed properly at the connection between the motor shaft head and the coupling, there will be a coaxiality deviation, which will generate uneven friction during operation, leading to accelerated wear of the shaft head.

[0003] During the use of ball mills, the shaft head is prone to wear and deformation, requiring repair to ensure normal operation. However, when machining the shaft head surface, the shaft end lathe uses a top-level alignment method, making it difficult to find the center axis point, resulting in inaccurate alignment and unstable quality of the repaired shaft head, which affects the normal operation of the ball mill. Therefore, it is necessary to provide a ball mill shaft head repair device that uses a four-way clamping alignment method to quickly align the shaft head, achieve accurate center alignment, and improve repair efficiency and quality.

Detailed Implementation

[0022] In the following description, embodiments of the ball mill shaft head repair device of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4 This invention illustrates a ball mill shaft head repair device according to an embodiment of the present invention, comprising a shaft end lathe 2 located on the right side of the shaft head 1; a fixing frame 3 is fixedly connected to the left side of the shaft end lathe 2, and a leveling cylinder 4 is fixedly installed on the left side of the shaft end lathe 2, with the left end of the leveling cylinder 4 in close contact with the right side of the shaft head 1; the cutting tool of the shaft end lathe 2 is in contact with the surface of the shaft head 1; a leveling assembly 5 is provided on the left side of the fixing frame 3, the leveling assembly 5 including a fixing plate 51; and four fixing posts 7 are fixedly connected to the left side of the fixing frame 3. The left end of column 7 is fixedly connected to fixed plate 51. Four rectangular grooves 9 are formed on the surface of fixed plate 51. Two limiting grooves 8, which are adapted to the rectangular grooves 9, are formed on the surface of pull plate 53. Through the combined use of the limiting grooves 8 and the rectangular grooves 9, the clamping block 52 is limited and guided, thereby improving the stability of the clamping block 52 during sliding. Four clamping blocks 52 are arranged in a ring on the left side of fixed plate 51. The right end of each clamping block 52 is rotatably connected to pull plate 53, and the clamping block 52 is held by the shaft head. On the surface of 1, the right ends of the four pull plates 53 are rotatably connected to threaded sleeves 54. The inner cavity of the fixed frame 3 is provided with a drive assembly 6, which includes a threaded tube 61. The two ends of the threaded tube 61 are rotatably connected to the fixed plate 51 and the fixed frame 3 respectively through bearings. The threaded sleeves 54 are threadedly connected to the surface of the threaded tube 61. A stepper motor 62 is fixedly installed at the bottom of the fixed frame 3. The output shaft of the stepper motor 62 passes through the inner cavity of the fixed frame 3 and is fixedly connected to a drive bevel gear 63. A force-bearing bevel gear 64 is fixedly connected to the right side of the surface of the threaded tube 61. The force-bearing bevel gear 64 meshes with the drive bevel gear 63. Through the setting of the drive assembly 6, the threaded tube 61 is driven to rotate under the drive of the stepper motor 62 and the cooperation of the drive bevel gear 63 and the force-bearing bevel gear 64. At the same time, the threaded tube 61 and the threaded sleeves 54 push and pull the pull plates 53, thereby allowing the clamping block 52 to slide and clamp the right end of the shaft head 1, thus achieving center alignment.

[0024] Working Principle: In use, the user moves the shaft end lathe 2 to the right side of the shaft head 1, then contacts the left side of the fixed plate 51 with the right end of the shaft head 1. The stepper motor 62 is then turned on, driving the drive bevel gear 63 to rotate. Since the drive bevel gear 63 and the force-bearing bevel gear 64 are in a meshing transmission state, the force-bearing bevel gear 64 rotates along with the drive bevel gear 63. During this rotation, the force-bearing bevel gear 64 drives the threaded tube 61 to rotate between the fixed plate 51 and the fixed frame 3. The threaded tube 61 rotates through... The threaded sleeve 54 is pushed to the right, which pulls the pull plate 53. During the movement, the pull plate 53 pulls the clamping block 52, causing the four clamping blocks 52 to move in opposite directions at the same time and clamp the right end of the shaft head 1. This makes the center point of the fixed plate 51 and the axis of the shaft head 1 lie on the same horizontal plane. Then, the alignment cylinder 4 is opened and passes through the threaded tube 61 and the inner cavity of the fixed plate 51 from right to left, making close contact with the right end of the shaft head 1, thereby performing center alignment. Then, the shaft end lathe 2 is turned on, and the shaft end lathe 2 drives the cutting tool to perform grinding and repair on the surface of the shaft head 1.

[0025] In summary, this ball mill shaft head repair device, through the coordinated use of the alignment component 5 and the drive component 6, clamps the right end of the shaft head 1. At the same time, through the coordinated use of the alignment cylinder 4, the shaft head 1 is centered and aligned. Finally, under the action of the shaft end lathe 2, the surface of the shaft head 1 is ground and repaired, thus achieving the purpose of rapid alignment and accurate center alignment.
