Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to a bearing outer ring machining equipment. Background Technology

[0002] As a crucial component in modern machinery, the precision of bearings directly affects the operating performance and service life of the machinery. In the manufacturing process of bearings, the grinding of the outer ring wall is a key step. To ensure the uniformity and smoothness of the grinding, the bearing needs to be firmly positioned and clamped on the processing platform before processing to prevent it from shifting or jumping during high-speed grinding.

[0003] Existing bearing outer ring machining equipment uses specialized internal support fixtures or external clamps to fix the bearings. Due to the wide variety of bearing specifications and models, with varying inner diameters and thicknesses, existing fixing devices often lack versatility. A single fixture can only accommodate one or a few bearing specifications. When the production line needs to switch to machining different bearing models, operators must stop the machine and manually disassemble the old fixture, install the new fixture, and repeatedly adjust and align it. This traditional method is not only time-consuming and labor-intensive, severely reducing production efficiency, but also prone to introducing installation errors through manual fixture changes, leading to inaccurate bearing positioning and affecting the concentricity and machining quality of the outer ring grinding. Furthermore, relying solely on a single internal support or external clamp method sometimes fails to provide sufficient clamping force for high-intensity grinding operations, easily causing the workpiece to loosen.

[0004] Therefore, this utility model proposes a bearing outer ring processing equipment to overcome the shortcomings of the prior art. Utility Model Content

[0005] In the existing technology, a bearing outer ring processing equipment often has poor versatility when dealing with bearings of different specifications and models. It requires frequent manual replacement of internal support positioning fixtures or external clamps of different sizes, resulting in a cumbersome and time-consuming operation process, low production efficiency, and the problem that manual assembly is prone to introducing errors, thereby reducing the processing and positioning accuracy, and the single fixing method is prone to workpiece loosening. The present invention aims to provide a bearing outer ring processing equipment with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a bearing outer ring processing equipment, including: a housing, a working groove in the middle of the outer wall of the housing, a base fixedly connected to the bottom of the working groove, a motor fixedly connected to the top of the base, a turntable fixedly connected to the output end of the motor, the turntable being located in the working groove, and a matching mechanism disposed on the inner wall of the housing.

[0007] The bottom of the guide head is fixedly connected to an extension arm, and the top of the extension arm is fixedly connected to a fitting arm; the processing equipment also includes a clamping plate and a fixed plate located above the clamping plate, and the outer wall of the fitting arm is slidably connected to the inner wall of the clamping plate.

[0008] The processing equipment also includes a second motor fixedly connected to the outer wall of the working groove. The output end of the second motor is connected to a threaded column through a transmission assembly. A movable seat is slidably connected to the outer wall of the threaded column. The movable seat is rotatably connected to the movable column through a connecting strip. The top of the movable column is connected to the bottom of the clamping plate and is used to push the clamping plate to move towards the fixed plate to clamp the bearing. A grinding machine is also fixedly connected to the outer shell. The output end of the grinding machine extends to one side of the fixed plate.

[0009] Preferably, the inner wall of the turntable cooperates with the guide head. When the motor drives the turntable to rotate, the guide head can slide back and forth along the radial direction of the turntable under force, thereby driving the extension arm and the fitting arm to move synchronously, realizing the function of converting rotational motion into radial linear motion.

[0010] Preferably, the clamping plate is slidably connected to the fitting arm to change the radial support position, thereby accommodating bearings with different inner diameters.

[0011] Preferably, the output end of the second motor is fixedly connected to an output shaft, the outer wall of the output shaft is fixedly connected to a gear, and one end of the threaded column is fixedly connected to a gear. The gears mesh with each other, and the stable transmission of power and speed regulation are achieved through the gear transmission group.

[0012] Preferably, a fixed shaft is fixedly connected to the top of the movable seat, one end of the connecting bar is rotatably connected to the fixed shaft, and the other end of the connecting bar is rotatably connected to the movable column, thereby connecting the horizontal moving parts and the vertical moving parts using a linkage mechanism.

[0013] Preferably, a fixed seat is also fixedly connected to the bottom of the inner wall of the working groove, and the movable column passes through the fixed seat and is slidably connected to the fixed seat. The fixed seat is used to limit the horizontal displacement of the movable column and guide its vertical lifting and lowering, thereby increasing the stability of the lifting and lowering process.

[0014] Preferably, the two ends of the threaded column are rotatably connected to the inner wall of the fixed seat or the working groove, and the movable seat is provided with threads that cooperate with the threaded column, so that the movable seat can be driven to move axially when the threaded column rotates.

[0015] Preferably, the fixed plate is fixedly connected to the center of the base or turntable, and the axis of the fixed plate is collinear with the rotation center of the turntable to ensure concentricity during clamping.

[0016] Preferably, the connecting strip is inclined, and the rotation connection points at both ends are located on the movable seat and the movable column, respectively. When the movable seat moves horizontally closer to the movable column, the connecting strip pushes the movable column upward, cleverly converting the horizontal thrust into a vertical lifting force.

[0017] Preferably, the grinder is fixedly mounted on the top plane of the housing, and the grinding head of the grinder is set vertically downward to facilitate the processing of the fixed bearing outer ring.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that the processing of bearings with different inner diameters requires frequent replacement of different specifications of inner support molds or fixtures, resulting in cumbersome operation and low production efficiency. It solves the problem that the existing technology requires frequent replacement of inner support molds or fixtures of different specifications, resulting in cumbersome operation and low production efficiency. It can adaptively radially support and position bearings with different inner diameters without changing molds, which significantly improves the versatility of the equipment and processing efficiency.

[0019] 2. This utility model solves the problem in the prior art of unstable axial fixing of bearings or difficulty in adapting to the clamping requirements of bearings of different thicknesses by setting a motor to drive the threaded column to rotate, and using the horizontal movement of the movable seat in conjunction with the tilt angle change of the connecting bar to push the movable column and clamping plate to rise and fall vertically. It achieves the ability to automatically adjust the height of the clamping plate according to the bearing thickness and firmly press the bearing onto the fixed plate, realizing stable axial locking, effectively preventing the bearing from shifting or shaking during the grinding process, thereby ensuring processing accuracy.

The guide head 204 slides radially back and forth along the inner wall of the turntable 203. An extension arm 205 is fixedly connected to the bottom of the guide head 204. A fitting arm 206 is fixedly connected to the top of the extension arm 205. When the extension arm 205 is pushed out by the guide head 204, the extension arm 205 drives the fitting arm 206 to slide and expand outward synchronously.
