Technical Field
[0001] The utility model relates to the technical field of bearing sleeve processing equipment, and particularly relates to a novel bearing race grinding machine. Background Art
[0002] A bearing race grinding machine is a precision machine tool specifically used for processing the inner and outer raceways of bearings. Its design and function are crucial for improving the production efficiency and precision of bearings.
[0003] Most of the existing grinding machines adopt two sets of clamping mechanisms, which are respectively used for processing the outer and inner rings of the bearing sleeve. Although this method can achieve the grinding and processing of the inner and outer raceways of the bearing sleeve, the setting of the two sets of clamping mechanisms increases the volume of the grinding machine and brings many inconveniences during the installation and unloading of the bearing sleeve.
[0004] Therefore, this application provides a novel bearing race grinding machine to meet the requirements. Summary of the Utility Model
[0005] The purpose of this application is to provide a novel bearing race grinding machine, aiming to solve the problem that when the existing grinding machine clamps and limits the bearing sleeve, two sets of clamping mechanisms are required, which increases the volume of the grinding machine and is inconvenient to use.
[0006] To achieve the above purpose, this application provides the following technical solution: a novel bearing race grinding machine, including a robotic arm, and the robotic arm is used for the feeding and discharging operations of the bearing sleeve;
[0007] On one side of the robotic arm, there is also a bed body. A slideway is opened on the top surface of the bed body. An installation frame is slidably connected in the slideway. The installation frame is driven by a servo motor and can slide in the horizontal axis direction. An expansion cylinder is arranged on the installation frame. The expansion end of the expansion cylinder is connected with a grinding motor through an installation plate, and a grinding wheel is arranged on the output end of the grinding motor; by setting a limiting component on the bed body and cooperating with the robotic arm on the right side of the bed body, the automatic feeding, clamping and limiting, and automatic discharging operations of the bearing sleeve are realized, and the automatic grinding and processing of the bearing race are realized in cooperation with the grinding wheel on the bed body;
[0008] A rotating frame is also rotatably connected to the bed body. The rotating frame is driven by a rotating motor, and a limiting component for inner support or clamping of the bearing sleeve is arranged on the rotating frame.
[0009] Preferably, two sets of slideways are opened, and they are symmetrically arranged on the bed body. A guide rod and a lead screw are respectively arranged in the two sets of slideways. The lead screw is connected with the output end of the servo motor; the installation frame is in a "冂" shape, and slide holes adapted to the guide rod and threaded holes meshing with the lead screw are respectively opened on the installation frame.
[0010] Preferably, the rotating frame adopts a cylindrical frame, including an upper disk, a lower disk, and a vertical rod, wherein the upper disk and the lower disk are connected by the vertical rod.
[0011] Preferably, the limiting assembly includes clamping rods and a driving block. The upper disc has three sets of sliding grooves, and the clamping rods are slidably connected within these grooves. The lower disc is connected to the driving block via a driving cylinder. Under the drive of the driving block, the three sets of clamping rods can move towards or away from each other. By incorporating the driving block and clamping rods in the clamping assembly, along with the ball joint and inclined groove, when the driving block moves upward, the three sets of clamping rods can move away from each other, providing internal support for the bearing sleeve and facilitating the machining of the bearing's outer raceway. Conversely, it clamps and limits the bearing sleeve, facilitating the machining of the bearing's inner raceway. This increases the adaptability of the device while reducing its size.
[0012] Preferably, the slide groove is further provided with a slide rod, the clamping rod is provided with a through hole adapted to the slide rod, the bottom of the clamping rod is provided with a ball head, the driving block is frustum-shaped and is provided with an inclined groove that corresponds to the position and size of the ball head.
[0013] In summary, the technical effects and advantages of this utility model are as follows:
[0014] In this invention, by setting a limiting component on the bed, and cooperating with the robotic arm on the right side of the bed, the automatic feeding, clamping and limiting and automatic unloading of the bearing sleeve are realized. In addition, the automatic grinding of the bearing raceway is realized by cooperating with the grinding wheel on the bed.
[0015] In this invention, a drive block and clamping rods are provided in the clamping assembly, along with a ball head and a slanted groove. When the drive block moves upward, the three sets of clamping rods can move in opposite directions to provide internal support for the bearing sleeve and to process the outer raceway of the bearing. Conversely, they can clamp and limit the bearing sleeve to process the inner raceway of the bearing, thereby increasing the adaptability of the device and reducing the size of the equipment.

[0024] A bed body 2 is further provided on one side of the robotic arm 1. A slideway 3 is opened on the top surface of the bed body 2. An installation bracket 4 is slidably connected in the slideway 3. The installation bracket 4 is driven by a servo motor 12 and can slide in the horizontal axis direction. A telescopic cylinder 10 is provided on the installation bracket 4. The telescopic end of the telescopic cylinder 10 is connected with a grinding motor 9 through a mounting plate 11, and a grinding wheel 8 is provided on the output end of the grinding motor 9;
[0025] Two groups of the slideways 3 are opened and symmetrically arranged on the bed body 2. A guide rod 14 and a lead screw 13 are respectively provided in the two groups of slideways 3. The lead screw 13 is connected with the output end of the servo motor 12; the installation bracket 4 is in the shape of "冂", and a sliding hole adapted to the guide rod 14 and a threaded hole meshing with the lead screw 13 are respectively opened on the installation bracket 4.
[0026] A rotating bracket 5 is further rotatably connected to the bed body 2. The rotating bracket 5 is driven by a rotating motor, and a limit component for inner supporting or clamping of the bearing sleeve is provided on the rotating bracket 5.
[0027] The rotating frame 5 adopts a cylindrical frame, including an upper disk, a lower disk, and a vertical rod. The upper disk and the lower disk are connected by the vertical rod. The upper disk is flush with the top surface of the bed 2. The lower disk has teeth on its outer side. A gear that meshes with the teeth is connected to the output end of the rotary motor. Through the meshing relationship between the gear and the teeth, the rotary motor drives the rotating frame 5 to rotate, and cooperates with the grinding wheel 8 to grind the bearing raceway.
[0028] The limiting assembly includes a clamping rod 6 and a driving block 17. The upper disc has a sliding groove 7, and there are three sets of sliding grooves 7. The clamping rod 6 is slidably connected in the sliding groove 7. The sliding rod 18 is also provided in the sliding groove 7. The clamping rod 6 has a through hole adapted to the sliding rod 18.

[0030] When the outer raceway of the bearing needs to be ground, the bearing sleeve to be ground is placed on the rotating frame 5 by the robotic arm 1. At this time, the three sets of clamping rods 6 are located inside the bearing sleeve. The drive cylinder 15 is extended to drive the drive block 17 to move upward. Through the cooperation of the inclined groove 16 and the ball head 19, the clamping rods 6 are pushed upward. Under the limit of the slide rod 18, the clamping rods 6 cannot move upward. The ball head 19 can only slide along the inclined groove 16, so that the three sets of clamping rods 6 move in opposite directions in the slide groove 7 to provide internal support and limit the bearing sleeve.

By engaging with the threaded hole on the mounting bracket 4, the mounting bracket 4 is driven to slide in the horizontal direction.
