[0002] In the prior art, mounting holes are provided on the wheel hub of an electric vehicle for docking and mounting with a vehicle frame. The drilling technology of the wheel hub of an electric vehicle in the prior art is relatively simple, and usually requires the provision of a fixture and a drilling mechanism. The fixture is mainly used for clamping and fixing the workpiece, and the drilling mechanism is used for drilling at a specified position. The drilling mechanism used for the wheel hub of an electric vehicle in the prior art is as follows:

[0003] For example, the patent document with publication (announcement) number: CN 114346284 A discloses "an electric vehicle wheel hub drilling device". The technical solution includes a base, a support block is fixedly connected to the lower surface of the base, a positioning mechanism is arranged on the upper surface of the base, a support frame is fixedly connected to the upper surface of the base, a drilling mechanism is arranged inside the support frame, and the present invention drives the threaded rod to move toward the inside of the movable groove through the contact plate, and the rotating plate rotates due to the interaction between the threaded rod and the rotating plate during the downward movement, and the sliding rod moves outward due to the interaction between the first sliding groove and the sliding rod, and the sliding rod moves outward under the action of the second spring, and the movable block drives the first positioning block to move outward, and when the first positioning block cannot contact the inner wall of the movable groove after moving outward, the third spring causes the first positioning block to move upward, thereby positioning the wheel hub.

[0011] A fixed outer cylinder is also installed at the left end surface of the left movable plate, and the setting position of the outer cylinder corresponds to the position of the left end of the inner cylinder, and the inner diameter of the outer cylinder is larger than the outer diameter of the inner cylinder. The drill bit passes through the outer cylinder, the inner cylinder and the clamping ring in sequence to drill a hole in the electric vehicle wheel hub; an air suction device is also installed at the left end of the lower fixed plate, and an air suction duct is also installed on the air suction device, which is connected to the lower end of the outer cylinder, and a filter is also provided at the end of the air suction duct.

[0017] Beneficial effects: The present invention has the following beneficial effects:

[0018] (1) In the present invention, an inner hole is provided on the left movable plate, and the setting position of the inner hole corresponds to the position of the drilling mechanism and also corresponds to the position of the hole to be drilled on the wheel hub of the electric vehicle. At the same time, a rotatable inner cylinder is installed in the inner hole, and the inner diameter of the inner cylinder is set so that the drill bit can pass through the inner cylinder to drill the wheel hub of the electric vehicle. When the drill bit is drilling, debris will be generated accordingly. Since the inner cylinder is set to a tapered hole structure with a wide outer side and a narrow inner side, the debris generated by the drilling will directly pass from the inner cylinder to the inner cylinder. In addition, when drilling, it is possible to generate strips of large-sized debris, which are difficult to be discharged from the inner cylinder. The present invention sets the inner cylinder to be rotatable. When drilling, the inner cylinder rotates accordingly, so the debris generated by drilling can be easily discharged to the outside.

[0019] (2) The clamping ring in the present invention has multiple functions. On the one hand, it is convenient for the left movable plate to clamp and fix the electric vehicle wheel hub without excessive pressure. On the other hand, after the electric vehicle wheel hub is clamped by the clamping ring, when drilling is performed, the debris generated by drilling will be directly discharged outward from the clamping ring and the inner cylinder, and the debris will not fall into the inner clamping and positioning area to avoid affecting the positioning of the workpiece. Another very important point is that the drill bit can be lubricated. The upper end of the clamping ring is connected to an oil injection pipe, and an oil injection device is installed on the upper fixed plate. The oil injection device can inject lubricating oil into the clamping ring. When the drill bit passes through the clamping ring, it is lubricated by the lubricating oil accordingly, which can reduce the wear of the drill bit and increase its service life.

[0020] (3) In the present invention, a fixed outer cylinder is arranged at the left end surface of the left movable plate. The arrangement position of the outer cylinder corresponds to the arrangement position of the inner cylinder, and the lower end of the outer cylinder is connected to a suction duct, which is connected to the suction device. The inner clamping ring can inject lubricating oil into the inner cylinder, and the excess lubricating oil will flow through the inner cylinder, which is wide outside and narrow inside, and flow into the outer cylinder. The suction duct of the outer cylinder generates a large suction force, thereby recovering the excess lubricating oil. The lubricating oil can be recycled accordingly. The filter net arranged in addition can filter debris, etc.; and the outer cylinder is arranged on the outside, which can further prevent the debris from collapsing, so that the debris can be discharged smoothly.

[0021] (4) In the overall structure of the present invention, the rotatable inner cylinder in the middle is responsible for discharging the debris generated by drilling, the inner clamping ring is responsible for injecting lubricating oil to lubricate the drill bit and cooperating to discharge the debris so that the debris does not fall into the clamping positioning area, and the outer cylinder on the outside is responsible for recovering excess lubricating oil. The outer cylinder can also prevent the discharged debris from collapsing and causing safety hazards by setting up a safety cylinder. The structure is very ingenious and reasonable.

The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0025] When the present invention is in use, after the electric vehicle wheel hub is placed in the clamping positioning area, the electric vehicle wheel hub can be pressed and fixed by the left movable plate; and the height and position of the drilling mechanism arranged on the left side correspond to the position of the hole to be drilled on the wheel hub.

[0027] In the present invention, an inner hole is provided on the left movable plate, and the setting position of the inner hole corresponds to the position of the drilling mechanism, and also corresponds to the position of the hole to be drilled on the wheel hub of the electric vehicle. At the same time, a rotatable inner cylinder is correspondingly installed in the inner hole, and the inner diameter of the inner cylinder is set so that the drill bit can pass through the inner cylinder to drill the wheel hub of the electric vehicle; when the drill bit is drilling, debris will be generated accordingly. Since the inner cylinder is set to a tapered hole structure with a wide outer side and a narrow inner side, the debris generated by the drilling will be directly discharged from the inner cylinder to the outside. In addition, when drilling, it is possible that strips of large debris are generated, which are difficult to be discharged from the inner cylinder. The present invention arranges the inner cylinder to be rotatable, and the inner cylinder rotates accordingly while drilling, so the debris strips generated by drilling can be easily discharged to the outside. After being discharged from the inner cylinder, these debris fall at the same place, which is very convenient to clean, and the debris will not fall, which increases the safety factor, and the generated debris will not fall into the clamping positioning area, which will not affect the positioning.

Another very important point is that the drill bit can be lubricated. The upper end of the clamping ring is connected to an oil filling pipe, and an oil filling device is installed on the upper fixed plate. The oil filling device can inject lubricating oil into the clamping ring. When the drill bit passes through the clamping ring, it is lubricated by the lubricating oil. This can reduce the wear of the drill bit and increase its service life.

[0030] A fixed outer cylinder 15 is also installed at the left end surface of the left movable plate 4. The setting position of the outer cylinder 15 corresponds to the position of the left end of the inner cylinder 11, and the inner diameter of the outer cylinder 15 is larger than the outer diameter of the inner cylinder 11.

[0033] In the overall structure of the present invention, the rotatable inner cylinder in the middle is responsible for discharging debris generated by drilling, the inner clamping ring is responsible for injecting lubricating oil to lubricate the drill bit and cooperating to discharge the debris so that the debris does not fall into the clamping positioning area, and the outer cylinder on the outside is responsible for recovering excess lubricating oil.
