Description

Technical Field

[0001] The utility model relates to the manufacturing and processing of bearings, and particularly to a clamping device of a bearing transfer mechanism. Background Art

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support a mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

[0003] In the early form of linear motion bearings, a row of wooden rods was placed under a row of pry bars. Modern linear motion bearings use the same working principle, except that sometimes balls are used instead of rollers. The simplest rotating bearing is a bushing bearing, which is just a bushing clamped between a wheel and an axle. This design was subsequently replaced by rolling bearings, where many cylindrical rollers replace the original bushing, and each rolling element is like an individual wheel.

[0004] After a bearing undergoes one process, it needs to be conveyed to the next machine for the next process by a conveyor belt. From the conveyor belt to the machine, manual or mechanical transfer is required. The transfer mechanism is provided with a clamping device for picking up and placing the bearing. The existing clamping device drives two clamping blocks to approach each other to clamp the bearing through two cylinders. Since both the inner ring and the outer ring of the bearing are circular rings, the contact area between the clamping device and the bearing is small, and the clamping stability is not high. The clamping device needs to increase the number of clamping blocks to increase the contact area with the bearing, and increasing the clamping blocks requires adding corresponding driving mechanisms, which increases the cost. Moreover, the existing clamping device has a low applicable range for bearings with different diameters. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a clamping device of a bearing transfer mechanism, which has the advantages of increasing the contact area with the bearing, improving the clamping stability, and improving the applicable range.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A clamping device for a bearing transfer mechanism, comprising a transfer mechanism and a clamping device. The clamping device is fixedly connected to the transfer mechanism. The clamping device includes a motor, a cavity, and a groove plate. The cavity is fixedly connected to the transfer mechanism. The motor is fixedly connected inside the cavity. Four waist-shaped grooves are provided at the top of the cavity surface. Two adjacent waist-shaped grooves are perpendicular to each other. The four waist-shaped grooves are arranged in a rotational pattern around the center of the cavity surface top. The groove plate is rotatably connected inside the cavity. It also includes four clamping blocks. The four clamping blocks are respectively embedded in the waist-shaped grooves at the top of the cavity and are slidably connected to the cavity. The bottom of the clamping block extends from the waist-shaped groove into the cavity. Arc-shaped waist-shaped grooves are provided on the surface of the groove plate and are arranged in a rotational pattern around the center of the groove plate. The included angle formed between two adjacent arc-shaped waist-shaped grooves is equal. A roller is rotatably connected to the bottom of the clamping block inside the cavity. The innermost ends of the waist-shaped groove and the arc-shaped waist-shaped groove overlap. The roller is embedded in the arc-shaped waist-shaped groove. The groove plate is fixedly connected to the output shaft of the motor.

[0008] With the above technical solution, the transfer mechanism drives the clamping device to move, enabling the clamping block to penetrate into the inner ring of the bearing. The motor drives the groove plate to rotate. The arc-shaped waist-shaped groove exerts a force on the clamping block, driving the clamping block to move along the waist-shaped groove on the cavity surface, causing the four clamping blocks to move away from each other, approaching the inner wall of the bearing and contacting the inner wall of the bearing, generating pressure and friction on the bearing, clamping the bearing. The transfer mechanism transfers the bearing from the conveyor belt to the equipment. When the motor rotates in reverse, the clamping blocks move closer to each other, releasing the bearing. The four clamping blocks increase the contact area with the bearing, improving the clamping stability. The clamping blocks can move to any position in the waist-shaped groove and can be applicable to bearings of various diameters.

[0009] Preferably, the transfer mechanism includes a mounting frame. A vertical cylinder 1 is fixedly connected to the top of the mounting frame. The output shaft of the cylinder 1 is fixedly connected to a mounting plate. A horizontal cylinder 2 is fixedly connected to the mounting plate. The output shaft of the cylinder 2 is fixedly connected to a connecting plate. The connecting plate is slidably connected to the mounting plate. The cavity is fixedly connected to the connecting plate.

[0010] With the above technical solution, the cylinder 2 pushes the clamping device to move above the bearing, and the cylinder 1 pushes the mounting plate to drive the clamping device to descend, enabling the clamping block of the clamping mechanism to enter the inner ring of the bearing.

[0011] Preferably, a rubber pad is fixedly connected to the surface of the clamping block that contacts the clamped object.

[0012] With the above technical solution, the friction force on the bearing is increased, reducing damage to the bearing. BRIEF DESCRIPTION OF THE DRAWINGS
