[0002] The deep and long hole grinding module is an equipment module used for grinding deep and long holes. It can achieve high-precision grinding and ensure the dimensional accuracy, shape accuracy and surface quality of the holes. The traditional deep and long hole grinding module consists of a grinding wheel spindle, an electric push rod with high-precision feeding capability, a water spray pipe, a fixture and a driving device. The fixture clamps one end of the workpiece, and the driving device drives the workpiece to rotate. The electric push rod drives the grinding wheel spindle to grind the hole surface of the workpiece, and the water spray pipe sprays coolant to reduce the wear of the grinding wheel. However, during the operation of the deep and long hole grinding module, the workpiece hole is often parallel to the horizontal plane, resulting in the accumulation of chips in the grinding process of the grinding wheel inside the hole, which aggravates the wear of the grinding wheel to a certain extent and affects the surface quality of the hole. In order to solve the shortcomings of the existing technology, we proposed a deep and long hole grinding module. Utility Model Content

An adapter box 56 is provided at the bottom of the electric slide rail 52. The electric slide rail 52 is used to control the left and right movement of the adapter box 56. The bottom of the adapter box 56 is fixedly connected to a water spray pipe 57. A water tank 58 and a water pump 59 are fixedly mounted on the top of the base 1. The water pump 59 is located on one side of the water tank 58. The water inlet of the water pump 59 is fixedly connected to a connecting pipe 511, and the water outlet of the water pump 59 is fixedly connected to a hose 512.

[0022] Among them, the end of the connecting pipe 511 away from the water pump 59 is fixedly connected to the water tank 58, and the water pump 59 is communicated with the inner cavity of the water tank 58 through the connecting pipe 511.

[0023] The electric slide 52 can drive the adapter box 56 and the water spray pipe 57 to move left and right. Under the restriction of the vertical guide rod 51, the electric slide 52 can only move up and down. By turning the knob 54, the threaded rod 55 can be driven to rotate, thereby driving the electric slide 52 to move up and down, so that the water spray pipe 57 can be extended into the hole of the workpiece 4.

[0024] The end of the water spray pipe 57 away from the adapter box 56 is in a barb shape, and the middle section of the water spray pipe 57 is parallel to the length direction of the workpiece 4;

[0025] By extending the water spray pipe 57 deep into the hole of the workpiece 4, when the grinding wheel shaft grinds the inner wall of the workpiece 4, the water pump 59 pumps the coolant in the water tank 58 to the water spray pipe 57, and the end of the water spray pipe 57 sprays coolant from right to left to wash away the grinding chips.

[0028] The spring 67 can push the clamping block 64 to move toward the center of the ring 62, thereby clamping the workpiece 4. When the electromagnet 66 is energized, it can attract the iron block 65 away from the center of the ring 62, thereby driving the clamping block 64 to release the workpiece 4.

When the workpiece 4 is passed through the ring 62, the four electromagnets 66 are first energized to attract the four iron blocks 65 away from the center of the ring 62 so that the workpiece 4 can pass through the ring 62. Then, the four electromagnets 66 are disconnected from the power supply. Under the thrust of the four springs 67, the four clamping blocks 64 clamp the outer wall of the workpiece 4.
