AI Technical Summary
一方面，传统铣床所采用的装夹机构难以对轴承端盖形成稳定且精准的固定，加工过程中易因工件微小位移导致端面平面度超差，进而影响轴承安装后的同轴度与运行稳定性；另一方面，每次更换轴承端盖时均需重新进行定位校准，这种非连续化的加工模式极大限制了生产效率，难以满足现代制造业日益增长的批量加工需求
[0014]This application proposes a milling device for bearing end cap surface machining, the core design of which lies in the support ring structure set on the turntable. This support ring, as a load-bearing component of the bearing end cap, provides stable support for the bearing end cap to be machined. When the bearing end cap is placed on the support ring, a clamping block is inserted into the interior of the bearing end cap. The clamping action of the clamping block is achieved by the movement of a sliding sleeve. As the sliding sleeve moves, it drives the clamping block closer to the inner wall of the bearing end cap until the clamping surface of the clamping block is in close contact with the inner wall of the bearing end cap. The clamping surface of the clamping block adopts an arc-shaped design. This design can better conform to the curved shape of the inner wall of the bearing end cap, increasing the contact area between the clamping block and the inner wall of the bearing end cap, thereby improving the stability and reliability of clamping, effectively preventing the bearing end cap from shaking or shifting during machining, and ensuring the quality of milling. Furthermore, the turntable used in this application has a multi-station structure. This multi-station design allows the loading process and the milling process to be performed simultaneously. At one station of the rotary table, the operator can load bearing end caps; at another station, the clamped bearing end caps can be milled. This parallel operation greatly improves the processing efficiency of bearing end caps. This application also features an automatic bearing end cap release function. When the milled bearing end cap moves out of the milling station, the return spring activates. The return spring, through its own elastic force, moves the sliding sleeve in the opposite direction, thereby moving the clamping block away from the inner wall of the bearing end cap, ultimately achieving automatic separation of the clamping block from the bearing end cap. This automatic release function not only improves the automation level of the processing and reduces manual intervention, but also further enhances processing efficiency and reduces the labor intensity of the operators.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining equipment technology, specifically to a milling device for machining bearing end cap surfaces. Background Technology
[0002] Bearing end caps are important components in mechanical equipment used to fix, seal, and protect bearings. They are usually installed at both ends of the bearing housing or machine casing. Their design directly affects the bearing's operating performance, lifespan, and the overall reliability of the equipment.
[0003] Current milling processes for bearing end caps generally rely on traditional milling machines, but this method reveals multiple technical bottlenecks in practical applications. Firstly, the clamping mechanisms used in traditional milling machines struggle to provide stable and precise fixation for the bearing end caps. During machining, even minute workpiece displacements can lead to deviations in end face flatness, affecting the coaxiality and operational stability of the bearing after installation. Secondly, each bearing end cap replacement requires recalibration, a discontinuous machining process that severely limits production efficiency and fails to meet the growing batch processing demands of modern manufacturing. Furthermore, the high purchase cost, ongoing maintenance expenses, and relatively low machining efficiency of milling machines result in persistently high unit costs for bearing end cap milling, severely restricting the market competitiveness of enterprises.

[0013] The advantages of this utility model application compared to the prior art are:
[0014] This application proposes a milling device for bearing end cap surface machining, the core design of which lies in the support ring structure set on the turntable. This support ring, as a load-bearing component of the bearing end cap, provides stable support for the bearing end cap to be machined. When the bearing end cap is placed on the support ring, a clamping block is inserted into the interior of the bearing end cap. The clamping action of the clamping block is achieved by the movement of a sliding sleeve. As the sliding sleeve moves, it drives the clamping block closer to the inner wall of the bearing end cap until the clamping surface of the clamping block is in close contact with the inner wall of the bearing end cap. The clamping surface of the clamping block adopts an arc-shaped design. This design can better conform to the curved shape of the inner wall of the bearing end cap, increasing the contact area between the clamping block and the inner wall of the bearing end cap, thereby improving the stability and reliability of clamping, effectively preventing the bearing end cap from shaking or shifting during machining, and ensuring the quality of milling. Furthermore, the turntable used in this application has a multi-station structure. This multi-station design allows the loading process and the milling process to be performed simultaneously. At one station of the rotary table, the operator can load bearing end caps; at another station, the clamped bearing end caps can be milled. This parallel operation greatly improves the processing efficiency of bearing end caps. This application also features an automatic bearing end cap release function. When the milled bearing end cap moves out of the milling station, the return spring activates. The return spring, through its own elastic force, moves the sliding sleeve in the opposite direction, thereby moving the clamping block away from the inner wall of the bearing end cap, ultimately achieving automatic separation of the clamping block from the bearing end cap. This automatic release function not only improves the automation level of the processing and reduces manual intervention, but also further enhances processing efficiency and reduces the labor intensity of the operators.

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.
[0023] Reference Figures 1-6 As shown, this utility model application provides a milling device for machining the bearing end cover surface, including: a main body 1; a station switching component 2, disposed on the top of the main body 1 for fixing the bearing end cover and moving the bearing end cover into the milling station; and a milling component 3, disposed on the top of the main body 1 and on the back of the station switching component 2 for milling the surface of the bearing end cover. The station switching component 2 includes a turntable 21 rotatably disposed on the main body 1, and includes a first rotary drive component 211 disposed in the main body 1 for driving the turntable 21 to rotate. A plurality of fixing clamping components 22 for fixing the bearing end cover are evenly disposed on the turntable 21. Each fixing clamping component 22 includes a support ring 221 that can be fixed on the turntable 21 and used to support the bearing end cover, and a clamping block 223 disposed inside the support ring 221 and capable of contacting the inner wall of the bearing end cover.
[0024] During the processing, the bearing end cap to be processed is first placed on the support ring 221 of the fixed clamping assembly 22 on the turntable 21. At this time, the clamping block 223 contacts and clamps the inner wall of the bearing end cap, thus fixing the bearing end cap. Then, the first rotary drive 211 drives the turntable 21 to rotate, switching the station with the bearing end cap to the milling station. After the bearing end cap enters the milling station, the milling assembly 3 starts working to mill the surface of the bearing end cap. During the processing, when one bearing end cap has been milled, the first rotary drive 211 drives the turntable 21 to rotate again, moving the station out of the milling station, and simultaneously switching the next station with the unprocessed bearing end cap to the milling station to continue processing. This cycle is repeated to achieve continuous processing of multiple bearing end caps, greatly improving processing efficiency. Meanwhile, after the finished bearing end cover is removed from the milling machine, the clamping block 223 releases the bearing end cover, and the operator can remove it and place a new bearing end cover to be processed, in preparation for the next processing.
[0025] The fixed clamping assembly 22 includes a support rod 222 vertically positioned at the center of the support ring 221. The bottom of the support rod 222 is connected to a support member 2222 connected to the bottom of the turntable 21. A top plate 2221 is provided on the top of the support member 2222, and a guide groove is formed on the top plate 2221. The top plate 2221 serves as a guide for the movement of the clamping block 223, providing a track for its movement. The guide groove design restricts the movement direction of the clamping block 223, ensuring it can only move along a specific trajectory, thereby guaranteeing accurate contact between the clamping block 223 and the inner wall of the bearing end cover, achieving stable clamping of the bearing end cover. The clamping block 223 also has a guide rail that mates with the guide groove. The clamping surface of the clamping block 223 is arc-shaped. This design better conforms to the curved shape of the inner wall of the bearing end cover, increasing the contact area between the clamping block 223 and the inner wall of the bearing end cover, thereby improving the stability and reliability of the clamping.
[0026] The fixed clamping assembly 22 also includes a sliding sleeve 224 sleeved on the support rod 222 and capable of moving up and down for controlling the movement of the clamping block 223. A connecting rod 2231 is hinged to the sliding sleeve 224 and is hinged to the clamping block 223.
[0027] The fixed clamping assembly 22 also includes a lifting assembly 23 disposed at the bottom of the turntable 21 and used to drive the sliding sleeve 224 to move up and down. The lifting assembly 23 includes a vertically arranged telescopic drive member 231, and the output end of the telescopic drive member 231 is connected to a lifting member 2311 that can abut against the bottom of the sliding sleeve 224. The lifting member 2311 is also provided with a slot for the support member 2222 to be inserted.
[0028] When it is necessary to clamp and fix the bearing end cover, the telescopic drive 231 is activated, its output end extends, and drives the lifting member 2311 to move upward. Since the lifting member 2311 abuts against the bottom of the sliding sleeve 224, the upward movement of the lifting member 2311 pushes the sliding sleeve 224 to slide upward along the support rod 222. As the sliding sleeve 224 moves upward, the connecting rod 2231, which is hinged to the sliding sleeve 224, will rotate around the hinge point with the sliding sleeve 224, and at the same time drive the clamping block 223, which is hinged to the other end of the connecting rod 2231, to move along the guide groove on the top plate 2221 towards the inner wall of the bearing end cover.
[0029] The fixed clamping assembly 22 also includes a return spring 225 sleeved above the support rod 222, with one end of the return spring 225 connected to the bottom of the top plate 2221 and the other end of the return spring 225 connected to the top of the sliding sleeve 224.
[0030] After the bearing end cover is machined, the telescopic drive component 231 retracts, and the lifting component 2311 moves downward, no longer applying an upward thrust to the sliding sleeve 224. At this time, the return spring 225 releases its stored elastic potential energy, applying a downward thrust to the sliding sleeve 224, causing the sliding sleeve 224 to move automatically downward along the support rod 222. The downward movement of the sliding sleeve 224 drives the connecting rod 2231 to rotate in the opposite direction, causing the clamping block 223 to move away from the inner wall of the bearing end cover along the guide groove, thus separating the clamping block 223 from the bearing end cover and releasing the bearing end cover.
[0031] The milling assembly 3 includes a support plate 31 fixed to the top of the main body 1, and a slide rod 311 is vertically arranged at the front of the support plate 31. A slide plate 32 that can move up and down is slidably arranged on the slide rod 311. A second rotary drive member 33 is fixed at the top of the slide plate 32, and the output end of the second rotary drive member 33 passes through the slide plate 32 and is connected to a milling cutter 331. The milling assembly 3 also includes a lead screw 35 arranged at the center of the front of the support plate 31 and threadedly connected to the slide plate 32. A third rotary drive member 34 for driving the lead screw 35 to rotate is fixed at the top of the support plate 31.
[0032] Before the milling process begins, the second rotary drive 33 is activated. The output end of the second rotary drive 33 drives the milling cutter 331 to rotate at high speed, preparing for the milling process. The milling depth and position of the milling cutter 331 are determined according to the machining requirements of the bearing end cover. The operation of the third rotary drive 34 is controlled to drive the lead screw 35 to rotate. Because the slide plate 32 is threadedly connected to the lead screw 35, and the slide plate 32 is guided and restricted by the slide rod 311, when the lead screw 35 rotates, the slide plate 32 moves up and down along the lead screw 35 and the slide rod 311. While the slide plate 32 drives the milling cutter 331 to move up and down, the high-speed rotating milling cutter 331 performs milling on the bearing end cover placed in the machining position.
[0033] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
