Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing processing technology, and in particular to a general bearing hole structure. Background Technology
[0002] Mechanical parts often involve the movement of general-purpose bearings, which are usually used in various mechanical equipment and do not have specific design requirements.
[0003] During the machining of general-purpose bearings, a hole opener is used to open holes in the bearings to achieve functions such as oiling or balancing. However, the opening of general-purpose bearings requires limiting the movement of the bearings by clamping the outer wall with clamps. This machining method can only be used to open holes in the center hole of the bearing. If it is necessary to open holes in the outer wall of the bearing, the bearing must be placed in a limiting structure in another machining table, and the center hole of the bearing must be pressed against it by two clamping plates. However, the machining table cannot clamp the inside and outside of the bearing separately, which increases operating costs and results in low overall adaptability of the machining table, which also affects the efficiency of general-purpose bearing machining. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A general bearing hole-opening structure includes a support and a hole opener for opening the bearing. A rotating rod is rotatably mounted on the support, and a sleeve for placing the bearing is fixedly mounted on the rotating rod. The sleeve is provided with a clamping structure one for clamping the outer wall of the bearing from the outside, and a clamping structure two for clamping the center hole of the bearing from the inside.
[0007] Preferably, the rotating rod is vertically arranged, a handle is fixedly installed on the rotating rod, a circumferentially distributed limiting groove is provided on the support, and a limiting frame extending into the limiting groove is movably installed on the handle, and the limiting frame is a T-shaped structure.
[0008] Preferably, the clamp structure includes a motor fixedly installed on the sleeve, and a bidirectional lead screw is fixedly connected to the output end of the motor. Two matching nuts are slidably sleeved on the bidirectional lead screw, and a connecting rod is integrally connected to the nuts. A limiting plate that moves against the outer wall of the bearing is connected to the connecting rod by screws.
[0009] Preferably, the bidirectional lead screw is horizontally arranged, a guide block is fixedly installed on the nut, a guide rod that is movably connected to the guide block is fixedly installed on the sleeve, the connecting rod is an L-shaped structure, the limiting plate is an arc-shaped structure adapted to the bearing, and a soft pad that moves against the bearing is provided on the inner wall of the limiting plate.
[0010] Preferably, the clamp structure two includes a through hole opened on the sleeve and corresponding to the bearing center hole. A telescopic rod one is fixedly installed on the sleeve. A positioning post extending to the bearing center hole is fixedly installed on the telescopic rod one, and a vertical rod is fixedly installed on the positioning post. A slider symmetrically arranged is slidably sleeved on the vertical rod. Two abutment plates that move against the bearing center hole are slidably sleeved on the positioning post, and a connecting rod connects the abutment plates to the two sliders. A telescopic rod two connected to the sliders is fixedly installed on the positioning post.
[0011] Preferably, the contact plate is an arc-shaped structure adapted to the bearing center hole, and the outer wall of the contact plate is provided with a soft pad that moves against the bearing center hole.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figures 1-4 A general bearing hole-opening structure includes a support 1 and a hole opener for opening holes in the bearing. When the hole opener is powered on, it can open holes in the outer and inner walls of the bearing. This technical solution is existing technology and will not be elaborated on here. A rotating rod 2 is rotatably mounted on the support 1, and a sleeve 3 for placing the bearing is fixedly mounted on the rotating rod 2. The sleeve 3 is welded to the top of the rotating rod 2. The rotating rod 2 is vertically set, and a handle is fixedly mounted on the rotating rod 2. The support 1 has circumferentially distributed limiting grooves. A limiting frame extending into the limiting grooves is movably mounted on the handle, and the limiting frame has a T-shaped structure. The rotating rod 2 is rotated by pulling the handle. When the rotating rod 2 rotates, it drives the sleeve 3 and the bearing to rotate, thereby adjusting the opening of the bearing. The position of the rotating rod 2 can be limited by the limiting frame.
[0022] The sleeve 3 is equipped with a clamping structure that clamps the outer wall of the bearing from the outside.
[0023] The clamp structure includes a motor 4 fixedly installed on the sleeve 3, and a bidirectional lead screw 5 is fixedly connected to the output end of the motor 4. The motor 4 and the telescopic rod 10 are connected to the sleeve 3 by bolts. Two matching nuts 6 are slidably sleeved on the bidirectional lead screw 5, and a connecting rod 7 is integrally connected to the nut 6. A limiting plate 8 that moves against the outer wall of the bearing is connected to the connecting rod 7 by screws. The two limiting plates 8 clamp the outer wall of the bearing, so that the hole opener can perform hole opening operation at the center hole of the bearing.
[0024] The bidirectional lead screw 5 is horizontally positioned, and a guide block is fixedly installed on the nut 6. A guide rod that is movably connected to the guide block is fixedly installed on the sleeve 3. When the guide block slides on the guide rod, the guide rod guides the guide block, thereby limiting the movement direction of the nut 6. The connecting rod 7 has an L-shaped structure, and the limiting plate 8 has an arc-shaped structure adapted to the bearing. The inner wall of the limiting plate 8 is provided with a soft pad that abuts against the bearing. By setting the limiting plate 8 to an arc-shaped structure adapted to the bearing, the contact area between the limiting plate 8 and the bearing can be increased. By providing a soft pad on the inner wall of the limiting plate 8, the bearing can be protected during the limiting process.
[0025] The sleeve 3 is equipped with a clamping structure 2 that clamps the bearing center hole from the inside.
[0026] The clamp structure two includes a through hole 9 opened on the sleeve 3 and corresponding to the bearing center hole. A telescopic rod 10 is fixedly installed on the sleeve 3. A positioning post 11 extending to the bearing center hole is fixedly installed on the telescopic rod 10. A vertical rod 12 is fixedly installed on the positioning post 11. A symmetrically arranged slider 13 is slidably sleeved on the vertical rod 12. The vertical rod 12 guides the slider 13, thereby limiting the movement direction of the connecting rod 15.
[0027] Two contact plates 14 are slidably mounted on the positioning post 11, which move against the bearing center hole. A connecting rod 15 connects the contact plates 14 and the two sliders 13. A telescopic rod 16 connected to the sliders 13 is fixedly installed on the positioning post 11. The telescopic rod 16 is connected to the positioning post 11 by a fixing bolt. The two contact plates 14 move against the bearing center hole, so that the hole opener can perform hole opening operation on the outer wall of the bearing.
[0028] The contact plate 14 is an arc-shaped structure adapted to the bearing center hole, and a soft pad is provided on the outer wall of the contact plate 14 to move against the bearing center hole. The two ends of the connecting rod 15 are respectively connected to the slider 13 and the middle pin of the contact plate 14. The positioning post 11 is a cylindrical structure, and an elongated hole is provided on the positioning post 11 to guide the connecting rod 15. The elongated hole limits the movement direction of the connecting rod 15, so that the connecting rod 15 can drive the contact plate 14 to move smoothly. By setting the contact plate 14 to an arc-shaped structure adapted to the bearing center hole, the contact area between the contact plate 14 and the bearing center hole can be increased.
[0029] It should be noted that the specific models and specifications of the hole opener, motor 4, telescopic rod 10, and telescopic rod 2 16 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt existing technology in this field, so they will not be elaborated here.
[0030] The functional principle of this utility model can be explained through the following operation methods:
[0031] When it is necessary to drill holes in the outer wall of the bearing;
[0032] Place the bearing on sleeve 3 so that the bearing center hole corresponds to the through hole 9;
[0033] The extension and retraction of the output end of the telescopic rod 10 causes the positioning pin 11 to extend to the center hole of the bearing;
[0034] The extension and retraction of the output end of the telescopic rod 16 causes the slider 13 to slide on the upright rod 12. When the two sliders 13 move towards each other, they cause the connecting rod 15 to deflect. When the connecting rod 15 deflects in the long hole, it presses the abutment plate 14, so that the two abutment plates 14 abut against the bearing center hole from the inside, and then clamp the bearing from the inside.
[0035] The operator holds a hole opener to make a hole in the outer wall of the bearing, and drives the rotating rod 2 and the bearing to rotate by the handle, thereby adjusting the position of the hole in the bearing;
[0036] When it is necessary to drill a hole in the inner wall of the bearing;
[0037] Place the bearing on sleeve 3 so that the bearing center hole corresponds to the through hole 9;
[0038] The output of motor 4 drives the bidirectional lead screw 5 to rotate. When the bidirectional lead screw 5 rotates, it drives the two nuts 6 to move in opposite directions.
[0039] When the two nuts 6 move toward each other, they drive the connecting rod 7 to move. The nuts 6 drive the guide plate to slide on the guide rod, so that the connecting rod 7 drives the limiting plate 8 to clamp the outer wall of the bearing.
[0040] The bearing inner wall is drilled using a hole opener.
[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
