Description

Technical Field

[0001] The utility model relates to the field of bearing seats, and more specifically, to a bearing seat assembly which is convenient for disassembly and assembly with a bearing. Background Art

[0002] In some moving mechanisms, rotating parts or parts that require support and precise guidance of semiconductor testing equipment, bearings are used to reduce friction and ensure smooth operation, while bearing seats play the role of fixing and supporting bearings to ensure the normal operation and precision requirements of the entire equipment.

[0003] At present, traditional bearing seats are generally connected to bearings by interference fit. The combination between the two is very tight, and there is a large friction and clamping force. When disassembling, it is necessary to overcome this strong bonding force, and often a large external force is required to separate them. The operation is difficult, and forced disassembly may cause damage to the components. When installing, it is also necessary to apply a certain amount of pressure to press the bearing into the bearing seat, which is relatively troublesome to operate. If it is not installed properly, it may also affect the matching accuracy. In addition, long-term close fit may cause some minor adhesion or deformation, further increasing the difficulty of disassembly and assembly (not conducive to the assembly between the bearing seat and the bearing, or the repair and replacement of the bearing in the bearing seat).

[0004] Therefore, in order to solve the above technical problems, the present application proposes a bearing seat assembly that is easy to disassemble and assemble with a bearing. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a bearing seat assembly that is easy to assemble and disassemble from a bearing.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bearing seat assembly that is easy to disassemble and assemble with a bearing, comprising a bearing seat body and a bearing installed in the inner cavity of the bearing seat body, a mounting block is installed on the outer wall of the bearing, the interior of the bearing seat body extends outward along the inner cavity to form a groove for inserting the mounting block, the bearing seat body is located behind the groove and is fixedly connected with a baffle A for limiting the back of the mounting block, the surface of the bearing seat body is slidably connected with a baffle B for limiting the surface of the mounting block, and circular through grooves for the bearing to pass through are provided on baffle A and baffle B. After the bearing is inserted into the inner cavity inside the bearing seat body, it is restricted in the groove by baffle A and baffle B, and then the position of baffle B is fixed by a fixing structure.

[0007] Preferably, a guide rail A for sliding the slider A is fixedly connected to the top of the bearing seat body, and the surface of the slider A is fixed to the top of the baffle B through an L-shaped plate to maintain the linear movement of the baffle B relative to the bearing body.

[0008] Preferably, the fixing structure includes screws welded to both sides of the back of the baffle B, and circular holes for the screws to pass through are opened on both sides of the surface of the bearing seat body, and nuts are threadedly connected to the outer side wall of the screw.

[0009] Preferably, an elastic component for limiting the rotating rod supported by the bearing is provided at the rear end of the side of the guide rail A. When necessary, the rotating rod on the component that needs to maintain an angle on the semiconductor detection equipment is limited to prevent it from rotating due to the vibration of the equipment operation.

[0010] Preferably, the surface of the elastic component is fixed to the horizontal plates at the rear part of both sides of the guide rail A, and the through-slot seat is fixed to the back of the guide rail A, and the bottom ends of the horizontal plates are connected to the lower pressure plates through springs, and the lower pressure plates are fixedly connected with an arc plate, and the top end of the arc plate is fixedly connected with a vertical rod that moves linearly along the inside of the through-slot seat.

[0012] Preferably, a handle is fixedly connected to the top of the connecting plate for easy pulling, so that the staff can pull the connecting plate to move it conveniently.

[0013] Preferably, a through hole for a rod to pass through is provided at the contact portion between the baffle B and the mounting block, so as to facilitate the staff to take out the bearing in the bearing seat.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model places the bearing in the main body of the bearing seat, so that the mounting block on it abuts against the baffle A, and then pushes the baffle B to move toward the surface of the main body of the bearing seat, and the bearing seat B drives the movement of the slider A, and the slider A slides along the guide rail A to maintain the linear movement of the baffle B, so that the baffle B is close to the surface of the main body of the bearing seat, thereby blocking the surface of the mounting block, and the bearing can pass through the circular through grooves on the baffle A and the baffle B without being blocked, and the mounting block can be restricted in the groove by the baffle A and the baffle B, thereby restricting the bearing in the inner cavity of the main body of the bearing seat, and then the position of the baffle B is fixed by the fixing structure to realize the assembly of the bearing and the bearing seat. Similarly, it is only necessary to contact the fixing structure to fix the baffle B and push the baffle B to move in the direction away from the main body of the bearing seat, so that the bearing connecting the mounting block can be taken out from the inner cavity of the bearing seat, so that there is no need for the bearing and the bearing seat to fit closely, and the disassembly and assembly operation is simple, thereby solving the problem of the inconvenience of disassembly and assembly of the bearing and the bearing seat in the background technology;

[0016] 2. When necessary, the utility model can limit the rotating rod on the component that needs to maintain the angle on the semiconductor detection equipment through the elastic component to prevent it from rotating due to the vibration of the equipment operation, thereby affecting the accuracy of the detection;

[0017] 3.

DETAILED DESCRIPTION

[0024] like Figure 1-4As shown, the utility model provides a bearing seat assembly that is easy to disassemble and assemble with a bearing, comprising a bearing seat body 1, and a bearing installed in the inner cavity of the bearing seat body 1, a mounting block is installed on the outer wall of the bearing, the interior of the bearing seat body 1 extends outward along the inner cavity to form a groove 2 for inserting the mounting block, the bearing seat body 1 is fixedly connected to a baffle A3 behind the groove 2 to limit the back of the mounting block, the surface of the bearing seat body 1 is slidably connected to a baffle B4 to limit the surface of the mounting block, and circular through grooves 5 for the bearing to pass through are formed on the baffles A3 and B4. After the bearing is inserted into the inner cavity inside the bearing seat body 1, it is restricted in the groove 2 by the baffles A3 and B4, and then the position of the baffle B4 is fixed by a fixing structure 6, and the top of the bearing seat body 1 is fixedly connected to a guide rail A7 for sliding a slider A8, and the surface of the slider A8 is fixed to the top of the baffle B4 by an L-shaped plate 9.

[0025] During assembly, the bearing is placed in the bearing seat body 1 so that the mounting block thereon (the mounting block can be mounted on the bearing by screws) is against the baffle A3, and then the baffle B4 is pushed to move toward the surface of the bearing seat body 1, and the bearing seat B drives the movement of the slider A8, and the slider A8 slides along the guide rail A7 to maintain the linear movement of the baffle B4, so that the baffle B4 is close to the surface of the bearing seat body 1, thereby blocking the surface of the mounting block, and the bearing will not be blocked by the circular through grooves 5 on the baffles A3 and B4, and the mounting block can be restricted in the groove 2 by the baffles A3 and B4, thereby restricting the bearing in the inner cavity of the bearing seat body 1, and then the position of the baffle B4 can be fixed by the fixing structure 6 to realize the assembly of the bearing and the bearing seat. Similarly, it is only necessary to contact the fixing structure 6 to fix the baffle B4 and push the baffle B4 to move away from the bearing seat body 1, so that the bearing connecting the mounting block can be taken out from the inner cavity of the bearing seat, so that there is no need for a close fit between the bearing and the bearing seat, and the disassembly and assembly operation is simple.

[0026] The fixing structure 6 includes screws 61 welded on both sides of the back of the baffle B4, and circular holes 62 for the screws 61 to pass through are opened on both sides of the surface of the bearing seat body 1. Nuts are threadedly connected on the outer wall of the screw 61, that is, when the baffle B4 is close to the surface of the bearing seat body 1, the screw 61 thereon just passes through the circular hole 62 on the bearing seat body 1, and a nut is installed on the passed portion, so that the nut moves along the screw 61 to press against the other side of the bearing seat body 1, thereby fixing the baffle B4 on the surface of the bearing seat body 1. Similarly, by removing the nut, the baffle B4 can be pushed to move away from the bearing seat body 1, so that the screw 61 is pulled out of the circular hole 62.

[0027] Furthermore, a through hole 10 for a rod-like object to pass through is provided at the contact portion between the baffle B4 and the mounting block. When disassembling or assembling the bearing, the rod-like object (such as a metal rod, chopsticks, etc.) can be passed through the through hole 10 from the back of the bearing seat body 1, thereby pressing against the mounting block and moving toward the opening direction of the baffle B4, making it more convenient for the staff to remove the bearing from the bearing seat.

[0028] The utility model further improves the above-mentioned bearing seat assembly, and an elastic component 11 is provided at the rear end of the guide rail A7 to limit the rotating rod (on the semiconductor device) supported by the bearing, so that when necessary, the rotating rod on the component that needs to maintain the angle on the semiconductor detection device is limited to prevent it from rotating due to the vibration of the device operation, thereby affecting the accuracy of the detection. The specific structure of the elastic component 11 is as follows:

[0029] The surface of the elastic component 11 is fixed to the horizontal plate 111 at the rear part of both sides of the guide rail A7, and the through-slot seat 115 is fixed to the back of the guide rail A7, and the bottom ends of the horizontal plates 111 are connected to the lower pressure plate 113 through springs 112, and the lower pressure plates 113 are fixedly connected with an arc plate 114, and the top end of the arc plate 114 is fixedly connected with a vertical rod 116 that moves linearly along the inside of the through-slot seat 115, and the top end of the vertical rod 116 is fixedly connected with a guide rail B117 for sliding the slider B118, and the side end of the through-slot seat 115 is fixedly connected with a support platform 119, and the side end of the slider B118 is fixedly connected with a connecting plate 1110, and the top end of the connecting plate 1110 is fixedly connected with a handle 1111 for facilitating pulling it.

[0030] That is, the vertical rod 116 is pulled upward, and the vertical rod 116 moves upward along the straight line of the through slot seat 115 (it should be noted that the cross section of the vertical rod 116 is the same as the cross section of the through slot seat 115), thereby driving the arc plate 114 and the lower pressure plate 113 to move upward, and at the same time squeezing the spring 112 between the lower pressure plate 113 and the cross plate 111, so that the arc plate 114 is not in contact with the rotating rod supported by the bearing, and then the handle 1111 is used to push the connecting plate 1110 to move toward the support platform 119, so that the connecting plate 1110 moves to the top of the support platform 119 to resist the vertical rod 11 6, thereby preventing the arc plate 114 from moving downward. This is to cope with the situation where the rotating rod on the semiconductor equipment needs to be rotated. When the rotating rod needs to be kept stationary, the connecting plate 1110 is pushed down from the lower pressing platform 113 through the handle 1111, and the spring 112 begins to stretch in the opposite direction due to its elastic force, thereby driving the lower pressing plate 113 to move downward, and finally driving the arc plate 114 to move downward, so that the arc plate 114 is close to the surface of the rotating rod, and the rotating rod is restricted by the pressing force and friction force generated by the contact between the arc plate 114 and the rotating rod, so as to avoid the rotating rod being rotated due to the vibration of the equipment operation.

[0031] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
