Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a device for infinitely long grinding of spring end faces. Background Technique

[0002] A spring is a mechanical part that uses elasticity to work. A part made of elastic material deforms under the action of an external force and returns to its original state after the external force is removed. It is also called a "spring", generally made of spring steel. During the production process of a spring, the end face of the spring needs to be ground by a grinding device.

[0003] For example, a spring end face grinding device with the patent number CN220516268U includes a grinding machine, a grinding roller and a heat dissipation component. The heat dissipation component includes a cooling box, a diversion piece and a spray head. The grinding machine provides installation conditions for the grinding roller and the heat dissipation component. The grinding machine is powered on to drive the grinding roller, so that the grinding roller rotates and grinds the end face of the spring. The above document still has deficiencies. When in use, when the grinding roller rotates to grind the end face of the spring, the diversion piece is powered on to operate to introduce the grinding fluid in the cooling box into the spray head, and the spray head then sprays the grinding fluid onto the grinding roller to cool the grinding roller by water cooling, avoiding the heat generated by friction from accelerating the aging speed of the grinding roller and improving the durability of the grinding roller. However, when the device in the above document grinds the infinite length cross-section of the spring, the position of the spring will shift, which is not convenient for positioning the spring, thereby affecting the effect of infinitely long grinding of the spring end face. At the same time, the angle of the grinding roller in the above document is fixed, and it is not convenient to adjust the inclination angle of the grinding roller according to actual use. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem of inconvenient positioning of the spring, and to propose a device for infinitely long grinding of spring end faces.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] Design a device for infinitely long grinding of spring end faces, including a frame and an electric push rod. The electric push rod is fixedly connected inside the frame.

A clamping mechanism is arranged inside the bracket. A rotating mechanism is arranged inside the frame. A support rod is fixedly connected inside the frame. The frame is fixedly connected with the lower surface of the water tank.

[0007] Preferably, the clamping mechanism includes a worm. The outer walls at both ends of the worm are rotatably connected to the bracket through bearings. The worm is meshed with a worm gear. The worm gear is fixedly connected to the end of a double-headed stud. The outer walls at both ends of the double-headed stud are rotatably connected to the bracket through bearings. Two first threaded blocks are threadedly connected to the outer wall of the double-headed stud. A support plate is fixedly connected to the outer wall of the first threaded block. The outer wall of the support plate is slidably connected to the bracket. A clamping plate is fixedly connected to the outer wall of the support plate.

[0008] Preferably, the rotating mechanism includes a motor. The motor is fixedly connected to the upper surface of the frame. A screw rod is fixedly connected to the output shaft of the motor.

The outer wall of the second threaded block is slidably connected to the frame. A pin rod is fixedly connected to the surface of the second threaded block. The outer wall of the pin rod is slidably connected to a chute arranged inside the connecting rod. The end of the connecting rod is fixedly connected to a cross plate. The cross plate and the end of the support rod are rotatably connected through a pin shaft.

[0009] Preferably, the water tank is communicated with the input end of the liquid pump. The lower surface of the liquid pump is fixedly connected to the frame.

[0010] Preferably, a water pipe is fixedly connected to the output end of the liquid pump. The outer wall of the end of the water pipe is fixedly connected to the frame.

[0011] Preferably, a grinding machine is fixedly connected below the cross plate. A grinding roller is fixedly connected to the output end of the grinding machine.

[0012] For a device for infinitely long grinding of the end faces of springs proposed by the present utility model, the beneficial effects are as follows: Through the cooperation among the worm, the worm gear, the double-headed stud, the first threaded block, the support plate and the clamping plate, the spring to be ground is placed between the two clamping plates.

Both clamping plates are attached to the outer wall of the spring to clamp and position the spring. When infinitely long grinding the cross section of the spring, the position of the spring will not shift, facilitating the positioning of the spring.

[0013] Through the cooperation among the motor, the screw rod, the second threaded block, the pin rod, the connecting rod and the cross plate, the motor drives the screw rod to rotate. The screw rod drives the second threaded block to slide. The vertical height of the second threaded block changes. The second threaded block drives the pin rod to move.

After adjusting to the required angle, the motor is turned off, facilitating the adjustment of the inclination angle of the grinding roller according to actual use. Description of the Drawings
