Description

Technical Field

[0001] The utility model relates to the technical field of grinding machines, and more specifically, to a roller chamfering guide rail grinding machine. Background Art

[0002] A guide rail is a device for guiding and supporting moving parts. The rollers of the guide rail are generally cylindrical. During the operation of the guide rail, the contact part between the roller and the guide rail will bear a large pressure, and the chamfer at the edge of the roller can prevent the sharp corners from scratching the guide rail. The traditional roller chamfering guide rail grinding machine consists of main components such as a conveying device, a gripper, a fixture, a grinding tool, a driving device, and a cylinder. The gripper clamps the roller transported by the conveying device to the fixture, and the cylinder drives the driving device and the grinding tool to approach the roller. Finally, the driving device drives the grinding tool to rotate and grind the edge of the roller. However, the speed at which the gripper drives the roller to move to the fixture position is slow, which affects the work efficiency to a certain extent. Moreover, when the set movement trajectory of the gripper deviates, it will affect the accuracy of the fixture clamping the roller. To solve the deficiencies of the prior art, we have proposed a roller chamfering guide rail grinding machine. Content of the Utility Model

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a roller chamfering guide rail grinding machine to solve the problems that the speed at which the gripper drives the roller to move to the fixture position is slow, which affects the work efficiency to a certain extent, and when the set movement trajectory of the gripper deviates, it will affect the accuracy of the fixture clamping the roller.

[0004] To solve the above technical problems, the utility model provides the following technical solutions: A roller chamfering guide rail grinding machine, including a base, a conveying device and two driving devices are arranged above the base, both of the two driving devices are located on the left side of the conveying device, a clamping assembly is arranged in the middle of the two driving devices, and an adjusting assembly is arranged below the clamping assembly;

[0005] The clamping assembly includes a turntable, a first side baffle and an arc-shaped supporting plate. The first side baffle is fixedly connected to the outer surface of one side of the conveying device. The bottom of the first side baffle is fixedly connected to the arc-shaped supporting plate. A positioning groove is formed on the outer wall of the turntable. A servo motor is fixedly installed on the top of the base, and the output end of the servo motor is fixedly connected to the turntable. A first cylinder and a second cylinder are fixedly installed on the top of the base. One end of the push rod of the second cylinder is fixedly connected to a second side baffle. One end of the push rod of the first cylinder is fixedly connected to an arc-shaped clamping block. A push block is slidably connected to the inner wall of the arc-shaped clamping block. A supporting plate is fixedly connected to the outer surface of one side of the arc-shaped clamping block. A spring is fixedly connected to the outer surface of one side of the supporting plate, and the end of the spring away from the supporting plate is fixedly connected to the push block. An inclined rail and a material box are fixedly installed on the top of the base, and the arc-shaped clamping block and the material box are respectively located on the left and right sides of the inclined rail.

[0006] Among them, there are two side baffles one and two, which are symmetrically distributed on both sides of the width direction of the arc-shaped support plate. There are four positioning grooves, which are circumferentially and equally angularly arrayed around the central axis of the turntable.

[0007] Among them, the arc-shaped clamping block is located directly below the turntable. The four positioning grooves have a cylindrical contour, and the length direction of the push block is parallel to the length direction of the conveying device.

[0008] Among them, the adjusting assembly includes a bracket. The bracket is fixedly installed on the top of the base. A chute is provided on the top surface of the bracket. The bracket is slidably connected with a slider through the chute. A threaded rod is rotatably connected to the inner wall of the bracket. The slider is threadedly connected to the outer wall of the threaded rod. A cylinder three is fixedly installed on the top of the slider. One end of the push rod of the cylinder three is fixedly connected with a movable frame. A connecting rod is rotatably connected to the top of the movable frame. A slide rail is fixedly installed on the top of the base. An installation frame is slidably connected to the top of the slide rail. The output end of the driving device is fixedly connected with a grinding knife. One end of the threaded rod is fixedly connected with a knob.

[0009] Among them, there are two connecting rods, slide rails, installation frames and grinding knives, which are symmetrically distributed on both sides of the length direction of the movable frame. The two slide rails are both parallel to the direction of the central axis of the turntable, and the two slide rails are located on both sides of the width direction of the arc-shaped clamping block.

[0010] Among them, the length directions of the threaded rod and the cylinder three are parallel to the length direction of the conveying device.

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

[0012] Through the clamping assembly of the present utility model, including a turntable, the conveying device transports the roller workpiece to one of the positioning grooves. The servo motor drives the turntable to rotate clockwise by 90 degrees. At this time, the roller slides along the arc-shaped support plate to the top of the arc-shaped clamping block under the restriction of the two side baffles one and the two side baffles two. The cylinder one applies a thrust to clamp the roller. Then the cylinder two drives the two side baffles two to descend. At this time, chamfering processing can be carried out on both ends of the roller. After the processing is completed, the cylinder one drives the arc-shaped clamping block to descend. At this time, the spring pushes the push block to slide to the right, and pushes the roller workpiece into the inclined rail and falls into the material box. With the above structure, through the positioning grooves provided on the outer wall of the turntable, the roller can be sequentially driven to the processing position, and guided to the material box after the processing is completed, eliminating the gripper structure, accelerating the speed of moving the roller to the clamping position, improving the working efficiency of the device, and the side baffles one and two avoid the deviation of the roller position, improving the accuracy of clamping the roller and the flexibility of the device;

[0013] The utility model is provided with an adjusting component, including a movable frame. During the chamfering process, the push rod of the third cylinder contracts, driving the movable frame to move leftward. At this time, the two connecting rods respectively drive the two mounting frames to gradually approach the arc-shaped clamping block along the two sliding rails, and the grinding knives process both ends of the roller. If rollers of different lengths need to be processed or the size of the chamfer needs to be changed, the knob is rotated to drive the slider to slide along the threaded rod, thereby changing the initial positions of the two mounting frames relative to the two sliding rails. With the above structure, the third cylinder drives the movable frame to push or pull the two connecting rods, which can drive the two grinding knives to approach the roller workpiece simultaneously. The structure is simple and the processing effects at both ends of the roller are similar. Moreover, the size of the chamfer can be adjusted by the knob, improving the practicability of the device.
