Description

Technical Field

[0001] The utility model belongs to the technical field of bearing processing, in particular to a clamping tool for bearing processing. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies and reduce the mechanical load friction coefficient of the equipment during the transmission process.

[0003] When bearings are processed, they need to be clamped using a clamping tool to prevent the bearings from shaking during processing, which will cause the processing accuracy to decrease. Existing bearing clamping tools are generally composed of a screw and a clamping plate. The screw is directly connected to the clamping plate with threads, which makes it easy for workers to miscontrol the strength during clamping, resulting in the bearing being clamped and damaged, causing property losses. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a clamping tool for bearing processing, which solves the problem that workers easily fail to control the strength when clamping with existing bearing clamping tools, resulting in damage to the bearing and causing property loss.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping tool for bearing processing, comprising a mounting plate, a movable plate slidably connected to the top of the mounting plate, two inclined grooves are provided on the movable plate, a screw rod is threadedly connected to the movable plate, two clamping plates are slidably connected to the top of the movable plate, a movable rod is fixedly connected to one side of the clamping plate, a vertical rod is fixedly connected to the movable rod, a round cap is fixedly connected to one end of the vertical rod, a fixed rod is fixedly connected to the mounting plate, and the movable plate is slidably connected to the fixed rod.

[0006] As a further solution of the utility model: a handle is connected to one end of the screw rod, and a roller bearing is sleeved on the screw rod.

[0007] As a further solution of the utility model: four mounting holes are provided on the mounting plate, and anti-slip grooves are provided on the clamping plate.

[0008] As a further solution of the utility model: a circular hole is opened on the clamping plate, and a limiting rod is slidably connected to the clamping plate.

[0009] As a further solution of the utility model: a spring is sleeved on the limit rod, and one end of the limit rod is connected to a circular plate.

[0010] As a further solution of the utility model: a limiting hole is provided on the moving rod, and the limiting hole corresponds to the limiting rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The clamping tool for bearing processing is provided with an inclined groove, a screw rod, a clamping plate and a vertical rod. The bearing is placed between two clamping plates. The handle is turned to drive the screw rod to rotate so that the movable plate moves on the fixed rod. The guiding effect of the inclined groove makes the vertical rod drive the movable rod and the clamping plate to move away from or close to each other to clamp and loosen the bearing. The inclined groove guides and limits the vertical rod. When the handle is continued to be turned after the bearing is clamped, the inclined groove can block the vertical rod so that the two vertical rods will not drive the clamping plates to move close to each other, thereby preventing the bearing from being damaged due to operating errors of the staff.

[0013] 2. The clamping tool for bearing processing is provided with a round hole, a moving rod, a limit hole, a spring and a limit rod. When the splint needs to be replaced, the round plate is pulled to make the limit rod disengage from the limit hole, the splint is removed and replaced with a new splint. The round plate is pulled to drive the limit rod to move upward, the round hole is inserted into the moving rod, the round plate is loosened, and the spring will push the limit rod to insert into the limit hole to install the splint. When the splint is damaged, the splint can be quickly replaced, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-3 As shown, the utility model provides a technical solution: a clamping tool for bearing processing, including a mounting plate 1, on which four mounting holes 9 are opened. Due to the special design of the mounting holes 9, when the clamping tool is installed on the processing equipment through the mounting holes 9, it can be installed more conveniently, thereby improving work efficiency. Anti-slip grooves 11 are provided on the clamping plate 7. Due to the anti-slip grooves 11, when two clamping plates 7 clamp the bearing, the anti-slip grooves 11 can increase the friction between the clamping plates 7 and the bearing, thereby improving the clamping stability. A movable plate 6 is slidably connected to the top of the mounting plate 1.

[0020] Two inclined grooves 8 are provided on the movable plate 6, and a screw rod 3 is threadedly connected to the movable plate 6. A handle 4 is connected to one end of the screw rod 3. Because the handle 4 is provided, when the handle 4 is turned to drive the screw rod 3 to rotate, the handle 4 makes the screw rod 3 easier to rotate, thereby improving the convenience of operation. A roller bearing 5 is sleeved on the screw rod 3. Because the roller bearing 5 is provided, when the screw rod 3 rotates on the roller bearing 5, the friction is smaller, thereby facilitating the staff to turn the handle 4.

[0021] Two clamping plates 7 are slidably connected to the top of the movable plate 6. A round hole 12 is opened on the clamping plate 7. A limit rod 13 is slidably connected to the clamping plate 7. A movable rod 16 is fixedly connected to one side of the clamping plate 7. A vertical rod 18 is fixedly connected to the movable rod 16.

[0022] A round cap 10 is fixedly connected to one end of the vertical rod 18, a fixed rod 2 is fixedly connected to the mounting plate 1, the movable plate 6 is slidably connected to the fixed rod 2, a spring 14 is sleeved on the limit rod 13, a round plate 15 is connected to one end of the limit rod 13, and a limit hole 17 is provided on the movable rod 16, and the limit hole 17 corresponds to the limit rod 13.

[0023] The working principle of the utility model is:

[0024] Place the bearing between the two clamps 7, turn the handle 4 to drive the screw 3 to rotate so that the movable plate 6 moves on the fixed rod 2, and through the guiding effect of the inclined groove 8, the vertical rod 18 drives the movable rod 16 and the clamp 7 to move away from or approach each other to clamp or loosen the bearing. When the clamp 7 needs to be replaced, pull the circular plate 15 to make the limit rod 13 disengage from the limit hole 17, remove the clamp 7, and replace it with a new clamp 7. Pull the circular plate 15 to drive the limit rod 13 to move up, insert the circular hole 12 on the movable rod 16, loosen the circular plate 15, and the spring 14 will push the limit rod 13 to insert into the limit hole 17 to install the clamp 7.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0026] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
