Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a valve cover drilling device. Background Art

[0002] Prior art publication number CN216151156U discloses a drilling device for a valve cover of an automobile engine, comprising a box body, a first cylinder being provided at the bottom of the box body, a first telescopic rod being provided at one side of the first cylinder, a splint being provided at one end of the first telescopic rod, a water tank being provided at one side of the box body, a water pump being provided at the top of the water tank, an extraction pipe being provided at the bottom of the water pump, a nozzle being provided at one side of the water pump, a first motor being provided at the top of the box body, a first threaded rod being provided at the output end of the first motor, a sliding frame being provided at the outside of the first threaded rod, a second motor being provided at one side of the sliding frame, a second threaded rod being provided at the output end of the second motor, a sliding block being provided at the outside of the second threaded rod, and a limited space being provided inside the sliding frame. The bottom of the sliding block is provided with a drilling device, and the drilling device includes a second cylinder, a second telescopic rod is provided at the bottom of the second cylinder, a third motor is provided at one end of the second telescopic rod, an output end of the third motor is provided with a rotating shaft, and one end of the rotating shaft is provided with a drill bit, and a fixed device is provided on the outside of the third motor. The water inside the water tank is pumped out through a water pump and an extraction pipe, and the nozzle sprays the pumped water onto the surface of the drill bit, which not only prevents the debris generated by drilling from flying around and causing environmental pollution, but also can cool the drill bit to a certain extent, thereby improving the service life of the drill bit. The first motor drives the first threaded rod to rotate, and controls the sliding frame to move left and right. The second motor drives the second threaded rod to rotate, and controls the sliding block to move back and forth inside the box for precise positioning.

[0003] The above technical solution uses water spraying from the nozzle to reduce the amount of debris, but there is no effective recycling of the sprayed water flow, which increases the waste of resources. Furthermore, the position of the drilling device is adjusted using a multi-stage threaded rod in conjunction with a drive motor, which increases production costs. Utility Model Content

The water supply system includes a water supply tank and a water supply pump internally connected thereto. The output end of the water supply pump is communicated with a spray head arranged in the working chamber through a connecting pipe;

[0007] The cylinder head placement rack includes a first-level frame, a second-level frame and a fixed frame, wherein the fixed frame is in a "mouth" shape;

[0008] A water flow groove with a triangular cross-section is opened at the bottom of the inner surface of the working chamber. There are two water flow grooves, which are symmetrically arranged about the central axis of the working chamber.
