Description

Technical Field

[0001] This invention relates to the field of bearing housing processing, and in particular to a bearing housing end face grinding apparatus. Background Technology

[0002] A bearing housing end face grinding device is used for high-precision grinding of bearing housing end faces. Its core structure typically includes a grinding disc, a workpiece clamping system, and a power drive device. During operation, a motor drives the grinding disc to rotate at high speed. The bearing housing is fixed to the grinding disc by a clamp, ensuring full contact between the end face and the abrasive on the grinding disc surface. The grinding action achieves surface polishing and flatness adjustment. Simultaneously, a cooling system continuously sprays grinding fluid to cool, lubricate, and remove debris, ensuring a stable and efficient grinding process. Ultimately, the bearing housing end face meets the specified precision requirements. This device is suitable for mass production and precision machining of bearing components in mechanical manufacturing. However, during the grinding process, the bearing housing often needs to be adjusted. If done manually, workers would have to perform a large amount of repetitive work daily, resulting in inconsistent product quality and increasing the risk of occupational diseases for workers. Summary of the Invention

[0003] The purpose of this invention is to provide a bearing housing end face grinding device in order to solve the above-mentioned problems.

[0004] The present invention achieves the above objectives through the following technical solutions:

[0005] A bearing housing end face grinding device includes a hollow rotating platform for connection to an external robotic arm, a rotary block for adjusting the bearing housing, and an adjustment mechanism to assist the rotary block in adjusting the pressure during the grinding process. A motor is installed on one side of the upper end of the hollow rotating platform, and the output end of the motor is connected to a fixed plate located at the bottom of the hollow rotating platform. A rotary block is installed at the bottom of the fixed plate, and an adjustment mechanism is installed inside the fixed plate.

[0006] The adjustment mechanism includes a fixed base, which is fixed to the inner side of the fixed plate. The bottom surface of the fixed base is formed with a groove to restrict the sliding of the rotary block. The upper side of the rotary block is located in the groove, and the two sides of the upper end of the rotary block are connected to horizontal push limit blocks. The horizontal push limit blocks are slidably connected to the horizontal push limit blocks corresponding to the horizontal movement position of the rotary block. A reset spring is provided between the outside of the positioning rod and the horizontal push limit block.

[0007] A pressing rod is slidably connected to the horizontal push limiting block in the direction perpendicular to the horizontal movement direction of the turning block. A pressing groove is provided on the outer side of the pressing rod corresponding to the position of the fixed seat. A pressure block is provided on the inner side of the pressing rod inside the turning block. A hollow pressure spring plate is fixed to the bottom of the pressure block. The pressure block is chamfered corresponding to the position of the pressing rod.

[0008] Preferably, both ends of the extrusion rod are provided with ball heads.

[0009] Preferably, the extrusion groove is an inclined groove, and the extrusion rod at the initial position of the turn block corresponds to the largest dimension of the extrusion groove.

[0010] Preferably, the upper end of the pressure plate has an inverted V-shaped structure, and the lower end has a circular arc structure.

[0011] Preferably, the sliding distance of the turn block under the restriction of the horizontal push limit block is 2mm.

[0012] Compared with existing technologies, the beneficial effects are as follows:

[0013] 1. By using a hollow rotating platform, motor, and turntable, repetitive manual mechanical work is replaced, thereby improving work efficiency;

[0014] 2. By using the adjustment mechanism in conjunction with the rotary block, during the grinding process, when the rotary block adjusts the bearing housing, the bearing housing will be subjected to a reverse frictional force as it moves on the grinding disc. At this time, the rotary block will translate, and in conjunction with the downward deformation of the pressure spring plate, the pressure of the rotary block on the end face will increase, thereby increasing the fixing pressure of the rotary block on the bearing housing, avoiding excessive movement, and improving the stability when adjusting the bearing housing.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-9 As shown, a bearing housing end face grinding device includes a hollow rotary platform 1 for connecting to an external robotic arm, a rotary block 4 for adjusting the bearing housing, and an adjustment mechanism 5 for adjusting the pressure of the rotary block 4 during the grinding process. A motor 2 is installed on one side of the upper end of the hollow rotary platform 1. The output end of the motor 2 is connected to a fixed plate 3 located at the bottom of the hollow rotary platform 1. The rotary block 4 is installed at the bottom of the fixed plate 3, and the adjustment mechanism 5 is installed inside the fixed plate 3.

[0030] The adjustment mechanism 5 includes a fixed base 51, which is fixedly connected to the inner side of the fixed plate 3. The bottom surface of the fixed base 51 is formed with a groove to restrict the sliding of the rotating block 4. The upper side of the rotating block 4 is located in the groove, and the two sides of the upper end of the rotating block 4 are connected to the horizontal push limit block 52. The horizontal push limit block 52 is slidably connected to the positioning rod 521 corresponding to the horizontal movement position of the rotating block 4. A reset spring 522 is provided between the outside of the positioning rod 521 and the horizontal push limit block 52.

[0031] A pressing rod 53 is slidably connected to the horizontal pushing limit block 52 in the direction perpendicular to the horizontal movement direction of the rotating block 4. A pressing groove 531 is provided on the outer side of the pressing rod 53 corresponding to the fixed seat 51. A pressure block 54 is provided on the inner side of the pressing rod 53 inside the rotating block 4. A hollow pressure spring plate 55 is fixed to the bottom of the pressure block 54. A chamfer is formed on the pressure block 54 corresponding to the pressing rod 53.

[0032] In this embodiment, both ends of the compression rod 53 are provided with ball heads, which are used to compress and engage the rod to prevent jamming.

[0033] In this embodiment, the extrusion groove 531 is an inclined groove, and the extrusion rod 53 at the initial position of the turn block 4 corresponds to the largest size of the extrusion groove 531. During the lateral movement of the turn block 4, the extrusion groove 531 gradually compresses the extrusion rod 53.

[0034] In this embodiment, the upper end of the pressure plate 55 has an inverted V-shaped structure, and the lower end has an arc-shaped structure.

[0035] In this embodiment, the sliding distance of the turn block 4 is 2mm under the restriction of the horizontal push limit block 52.

[0036] Working principle: One end of the hollow rotating platform 1 is connected to an external robotic arm. The robotic arm and motor 2 are started, causing the rotating block 4 to move in relation to the bearing. This causes the bearing housing to rotate or move periodically along a preset trajectory. When the grinding disc rotates, the rotating block 4 moves the workpiece at a certain frequency, causing it to move on the grinding disc in a non-fixed trajectory. During the grinding process, since the surface roughness of the bearing end face has been processed to a very low level in the previous process, the grinding at this time is mainly used to remove small particles from the surface. When the rotating block 4 encounters large particles or a rough surface during the turning process, the rough surface will provide increased friction to the rotating block 4 in the opposite direction. The friction will cause the rotating block 4 to move laterally under the restriction of the groove on the fixed seat 51. Thus, the rotating block 4 decelerates relative to the bearing end face.

[0037] During the lateral movement, the extrusion groove 531 applies pressure to the extrusion rod 53, causing the extrusion rod 53 to retract inward. The retraction of the extrusion rod 53 extrudes the pressure block 54, causing it to move downward. The downward force of the pressure block 54 extrudes the upper surface of the pressure spring plate 55. The V-shaped and arc-shaped structures of the pressure spring plate 55 work together to convert the elastic force into pressure and transmit it downward to the bottom surface of the shift block 4. This increases the pressure of the shift block 4 on the bearing end, thus enhancing the fixing effect on the bearing housing. After passing through this area, the return spring 522 supports the shift block 4 to return to its original position.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
