A surface grinder for machining bearing housings

Abstract

This utility model relates to the field of bearing housing processing technology, specifically a surface grinder for processing bearing housings. It includes a grinder body with a grinding disc mounted on it. Below the grinding disc, a grinding table for controlling the feed of the bearing housing is located on the grinder body. A support frame is fixedly mounted on the grinding table. A rotating assembly for fixing and flipping the bearing housing to be processed is located on the top of the support frame. The rotating assembly has a locking component for fixing the bearing housing's posture. By setting up the rotating assembly, ball bearings, and positioning groove, the bearing housing can be flipped after processing one end face without secondary clamping, improving the overall grinding speed of the bearing housing. Simultaneously, during the flipping process, a spring pushes the control plate, causing the rotating shaft and connecting seat to reciprocate axially, making the bearing housing vibrate synchronously, shaking off the grinding dust adhering to the end face to be processed. Furthermore, the depth difference between the groove and the positioning groove allows for direct visual determination of whether the flipping is in place.

Description

Technical Field

[0001] This utility model relates to the field of bearing housing processing technology, and in particular to a surface grinder for processing bearing housings. Background Technology

[0002] Bearing housings, also known as winches, are key components that ensure the stable operation of bearings. Their core function is to provide support, positioning, and protection for the bearings. In the manufacturing process of bearing housings, the bearing bore end faces need to be ground to ensure the operational accuracy of the bearing housing after assembly. This type of grinding is usually done with a surface grinder, which uses a high-speed rotating grinding wheel to cut the workpiece surface. This not only accurately removes excess material but also effectively improves the flatness and smoothness of the workpiece surface, meeting the assembly and usage requirements of the bearing housing.

[0003] A surface grinder disclosed in Chinese Patent Publication No. CN223519284U uses guide posts to exert force on a limiting plate, restricting the grinding wheel and preventing it from shaking during grinding, thus improving grinding stability. However, according to surface grinders provided in related fields and existing technologies, traditional surface grinders, when grinding the double-end faces of a bearing housing, typically require grinding one end face first, followed by a second clamping of the bearing housing to process the other end face. This operation is cumbersome, not only consuming a significant amount of clamping and positioning time, but also severely restricting the overall grinding speed of the bearing housing. Furthermore, the dust generated during grinding easily adheres to the end face of the bearing housing to be processed, forming an impurity coating, which adversely affects the grinding accuracy and surface quality of subsequent end faces. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a surface grinder for processing bearing housings.

[0005] The purpose of this utility model is achieved through the following technical solution: a surface grinder for processing bearing housings, comprising a grinder body, a grinding disc mounted on the grinder body, a grinding table for controlling the feed of the bearing housing located below the grinding disc on the grinder body, a support frame fixedly mounted on the grinding table, a rotating component for fixing and rotating the bearing housing to be processed located on the top of the support frame, and a locking component for fixing the posture of the bearing housing located on the rotating component; The rotating assembly includes a spline sleeve rotatably mounted on the top of the support frame. The spline sleeve extends laterally through the support frame. A rotating shaft is installed inside the spline sleeve. A connecting seat and a control plate are fixedly provided at both ends of the rotating shaft, respectively. A fixing plate for assembling a bearing housing is fixedly provided at the end of the connecting seat away from the rotating shaft. A handle is fixedly provided on the side of the control plate away from the rotating shaft.

[0006] Preferably, a spring is sleeved on the rotating shaft at the position between the control plate and the support frame, and two balls are symmetrically arranged on the side of the connecting seat facing the support frame. The support frame has positioning grooves at the positions of the two balls.

[0007] Preferably, the support frame has a plurality of grooves evenly spaced at the positions corresponding to the rotation path of the ball bearing, and the depth of the grooves is less than the depth of the positioning groove.

[0008] Preferably, the locking assembly includes a push rod slidably mounted on the control plate, the push rod passing through the control plate in a direction parallel to the rotating shaft, a push block rotatably provided at one end of the push rod near the support frame, and a knob fixedly provided at the other end of the push rod away from the support frame.

[0009] Preferably, the control plate has a threaded hole corresponding to the position of the push rod, and the push rod has an external thread near the knob.

[0010] Preferably, the fixing plate has multiple positioning and mounting holes.

[0011] Preferably, the control plate has a limiting groove corresponding to the position of the spring.

[0012] The advantages of this surface grinder for machining bearing housings are as follows: By setting up a rotating assembly, balls, and positioning grooves, the bearing housing can be flipped after machining one end face without secondary clamping, achieving rapid connection between grinding of both end faces and improving the overall grinding speed of the bearing housing; at the same time, during the flipping process, the spring pushes the control plate to drive the rotating shaft and connecting seat to perform axial reciprocating motion, causing the bearing housing to vibrate synchronously, which can automatically shake off the grinding dust attached to the end face to be processed, avoiding dust adhesion from affecting the subsequent grinding quality. Moreover, the depth difference between the balls and the positioning grooves can be used to intuitively determine whether the flipping is in place, and with the help of the push rod for quick locking and unlocking, the operation process is simplified and the positioning accuracy is improved.

[0017] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, in part of which will be obvious from the description or may be learned by practice of the invention.

[0018] like Figures 1 to 7As shown, a surface grinder for machining bearing housings includes a grinder body 1, a grinding disc 2 mounted on the grinder body 1, a grinding table 3 for controlling the feed of the bearing housing located below the grinding disc 2, a support frame 4 fixedly mounted on the grinding table 3, and a rotating assembly 5 for fixing and rotating the bearing housing to be processed located on the top of the support frame 4. The rotating assembly 5 is equipped with a locking assembly 6 for fixing the bearing housing's posture. In use, the bearing housing is fixed on the rotating assembly 5, and then the grinder body 1 controls the grinding disc 2 to rotate and contact the end face of the bearing housing downwards. At the same time, the grinding table 3 controls the feed of the bearing housing through the support frame 4 and the rotating assembly 5 to grind the end face of the bearing housing. After one end face of the bearing housing is ground, the locking assembly 6 is released from the locking of the rotating assembly 5, and then the rotating assembly 5 drives the bearing housing to rotate so that the other end face faces upwards. Then the rotating assembly 5 is locked again, and the above grinding process is repeated to grind the end face. The grinding of both ends of the bearing housing can be completed without re-clamping the bearing housing, which is convenient and fast.

[0019] like Figures 2 to 6As shown, the rotating assembly 5 includes a spline sleeve 56 rotatably mounted on the top of the support frame 4. The spline sleeve 56 extends laterally through the support frame 4. A rotating shaft 53 is installed inside the spline sleeve 56. A connecting seat 52 and a control plate 54 are fixedly mounted at both ends of the rotating shaft 53, respectively. A fixing plate 51 for assembling a bearing housing is fixedly mounted at the end of the connecting seat 52 away from the rotating shaft 53. A handle 55 is fixedly mounted on the side of the control plate 54 away from the rotating shaft 53. A spring 57 is fitted onto the rotating shaft 53 between the control plate 54 and the support frame 4. A limit groove 10 is formed on the control plate 54 corresponding to the position of the spring 57 to limit the position of the spring 57. Two ball bearings 8 are symmetrically arranged on the side of the connecting seat 52 facing the support frame 4. The support frame 4 has positioning grooves 7 at the positions corresponding to the two balls 8. The support frame 4 also has several grooves 11 evenly spaced along the rotation path of the balls 8, with the depth of the grooves 11 being less than the depth of the positioning grooves 7. The fixing plate 51 has multiple positioning mounting holes that align with the mounting holes on the bearing housing legs. The bearing housing can be securely mounted on the fixing plate 51 using bolts. After assembly, one end face of the bearing housing faces upwards, and the rotation center of the bearing housing coincides with the axis of the rotating shaft 53. Simultaneously, the spring 57 presses against one side of the support frame 4, causing the control plate 54 to drive the end face of the connecting seat 52 to press tightly against the other side of the support frame 4 via the rotating shaft 53. The two... The ball bearings 8 are respectively inserted into the two positioning grooves 7 to achieve stable positioning of the bearing housing. After one end face of the bearing housing is polished, hold the handle 55 and rotate the control plate 54 and the rotating shaft 53. The rotating shaft 53 will drive the fixing plate 51 and the bearing housing to rotate synchronously through the connecting seat 52. During this process, the ball bearings 8 gradually roll out of the positioning grooves 7 and push the connecting seat 52 to drive the rotating shaft 53 and the control plate 54 to compress the spring 57. After the ball bearings 8 have completely rolled out of the positioning grooves 7, they will pass through the positions of several grooves 11. At this time, the spring 57 and the several grooves 11 cooperate with each other to continuously push the control plate 54 to drive the rotating shaft 53 and the connecting seat 52 to perform axial reciprocating motion (the spline sleeve 56 can ensure that the rotating shaft 53 rotates simultaneously). (Axial displacement is achieved at the same time), which causes the bearing box on the fixed plate 51 to vibrate back and forth, shaking off the grinding dust attached to the end face of the bearing box to be processed. After the bearing box is flipped, the positions of the two balls 8 are reversed and they fit into the two positioning grooves 7. Since the depth of the positioning groove 7 is greater than the depth of the groove 11, the operator can clearly feel the increase in the amplitude of axial movement, thus determining that the bearing box has been flipped into place, thereby realizing the flipping and positioning function of the bearing box. After the flipping is completed, since the flipping center of the bearing box coincides with the axis of the rotating shaft 53, the position of the end face to be processed will not change. There is no need to readjust the height of the grinding disc 2. The grinding process can be repeated to complete the grinding of the end face.

[0020] like Figure 3 , Figure 4 and Figure 7As shown, the locking assembly 6 includes a push rod 61 slidably mounted on the control plate 54. The push rod 61 passes through the control plate 54 in a direction parallel to the rotating shaft 53. A push block 62 is rotatably provided at the end of the push rod 61 near the support frame 4, and a knob 63 is fixedly provided at the end of the push rod 61 away from the support frame 4. A threaded hole 9 is provided on the control plate 54 corresponding to the position of the push rod 61, and an external thread 64 is provided on the push rod 61 near the knob 63. In the initial state, the push block 62 is pressed against one side of the support frame 4, and the external thread 64 on the push rod 61 is engaged with the threaded hole 9 of the control plate 54, so that the push rod 61 and the control plate 54 remain relatively fixed. At the same time, the end face of the connecting seat 52 is in close contact with the support frame 4. On the other side of the support frame 4, the axial position of the rotating shaft 53 and the connecting seat 52 is locked. When the connecting seat 52 cannot produce axial displacement, the circumferential rotation of the connecting seat 52 is also restricted because the ball 8 is stuck in the positioning groove 7, thus achieving automatic locking of the circumferential position of the connecting seat 52. Finally, the position of the fixing plate 51 and the bearing box is fixed. During the unlocking operation, the push rod 61 is rotated by the knob 63, so that the external thread 64 on the push rod 61 is disengaged from the threaded hole 9 of the control plate 54. At this time, the push rod 61 can slide freely in the threaded hole 9, and the axial limiting effect is released, thus unlocking the axial position of the connecting seat 52, and then the machining end face of the bearing box can be flipped and switched.

[0021] The work process is as follows: S1: As Figure 1 and Figure 2 As shown, during use, the bearing housing is fastened to the fixed plate 51 with bolts. Then, the grinding disc 2 is controlled to rotate and contact the end face of the bearing housing downward through the grinding machine body 1. At the same time, the grinding table 3 controls the feed of the bearing housing through the support frame 4 and the rotating assembly 5 to grind the end face of the bearing housing. S2: As Figure 3 , Figure 4 and Figure 7 As shown, after one end face of the bearing housing is polished, the push rod 61 is rotated by the knob 63 to disengage the external thread 64 on the push rod 61 from the threaded hole 9 of the control plate 54. At this time, the push rod 61 can slide freely in the threaded hole 9, the axial limiting effect is released, and the axial position of the connecting seat 52 is unlocked. At this time, the control plate 54 and the rotating shaft 53 are rotated by holding the handle 55. The rotating shaft 53 will drive the fixing plate 51 and the bearing housing to rotate synchronously through the connecting seat 52. S3: As Figures 4 to 6As shown, during the flipping process, the ball 8 gradually rolls out of the positioning groove 7 and pushes the connecting seat 52 to drive the rotating shaft 53 and the control plate 54 to compress the spring 57. After the ball 8 has completely rolled out of the positioning groove 7, it will pass through the positions of several grooves 11. At this time, the spring 57 and several grooves 11 cooperate with each other to continuously push the control plate 54 to drive the rotating shaft 53 and the connecting seat 52 to make axial reciprocating motion, thereby causing the bearing box on the fixed plate 51 to vibrate back and forth, shaking off the grinding dust attached to the end face of the bearing box to be processed. S4: As Figures 4 to 6 As shown, after the bearing housing is flipped, the positions of the two balls 8 are reversed and they fit into the two positioning grooves 7. Since the depth of the positioning groove 7 is greater than the depth of the groove 11, the operator can clearly feel the increase in the amplitude of axial movement, thereby determining that the bearing housing has been flipped into place, thus realizing the flipping and positioning function of the bearing housing. S5: As Figure 1 and Figure 3 As shown, after the flipping is completed, the position of the connecting seat 52 and the fixing plate 51 is re-locked by the top rod 61. At this time, since the flipping center of the bearing box coincides with the axis of the rotating shaft 53, the position of the end face to be processed will not change after the flipping. There is no need to readjust the height of the grinding disc 2. The grinding process can be repeated to complete the grinding of the end face.
