[0024] The utility model provides Figure 1-Figure 5 A drilling structure for processing a motor shell is shown, and its basic structure includes a frame 1 and a drilling mechanism 2. The drilling mechanism 2 is installed on the frame 1, and the drilling mechanism 2 includes a slide rail 21, a loading platform 22, and a drilling unit 23. The slide rail 21 is fixed on the frame 1, and the loading platform 22 is slidably connected to the slide rail 21. The loading platform 22 is used to carry the motor shell to be drilled. A number of clamps of different shapes can be connected to the drilling mechanism 2 by fasteners to improve the stability of the motor shell during transportation. In addition, a drilling unit 23 is also installed on the frame 1. The drilling unit 23 includes a control unit, a motor and a drill bit. The output shaft of the motor and the drill bit are fixedly connected. When the loading platform 22 equipped with the motor shell moves to the bottom of the drilling unit 23, the drill bit in the drilling unit 23 drills the corresponding position of the motor shell. Because the structure of the drilling unit 23 is a prior art and is not an improvement point of the present application, its specific structure is not described here.

[0025] Example 1

[0026] On the basis of the above basic mechanism, a cleaning mechanism 3 is designed, including a slide 31, a contact plate 32, a scraper 33, a push plate 34, a connecting rod 35, and a top head 36, wherein a slide 31 is fixed on the frame 1, and the extension direction of the slide 31 is perpendicular to the extension direction of the slide rail 21. A cylinder is installed on the slide 31, and the cylinder body of the cylinder is fixedly connected to the frame 1, and the telescopic rod of the cylinder is slidably connected to the cylinder body, and the telescopic rod is fixedly connected to the push plate 34. A control unit for driving the telescopic rod to slide in the cylinder body is arranged in the cylinder body, and the control unit is electrically connected to an external controller, or other similar components with thrust function. The push plate 34 is slidably connected to the slide 31, and the contact plate 32 is fixed on the slide 31, so that when the cylinder drives the push plate 34 to be pushed out, the push plate 34 can clamp and fix the motor housing with the contact plate 32 from both sides, which is convenient for the subsequent drilling.

[0027] Furthermore, a top head 36 is fixed on the push plate 34 through a connecting rod 35, and a scraper 33 is vertically slidably connected to the contact plate 32. The scraper 33 and the top head 36 form a wedge block structure. By utilizing the mutual extrusion between the inclined surfaces of the top head 36 and the scraper 33, when the top head 36 pushes the scraper 33, the scraper 33 can be lifted up. By utilizing the sliding of the scraper 33 along the surface of the contact plate 32, the chips adhering to the surface of the contact plate 32 can be scraped off, thereby reducing the interference of the accumulated chips on the positioning of the motor housing.

[0028] The scraper 33 can have various structural shapes. The preferred scraper 33 is a complete frame structure, or a frame structure with an opening on the side. Generally, a middle space needs to be reserved so that the contact plate 32 can contact one end of the motor housing to achieve the purpose of clamping the motor housing.

[0029] Furthermore, the top of the scraper 33 of the frame is provided with a sharp corner with the tip pointing upward, so that the mixture of the scraped cutting fluid and chips can be left along the two inclined surfaces of the sharp corner, thereby reducing the probability of chips remaining on the abutment plate 32.

[0030] Example 2

[0031] On the basis of the above structure, a spray mechanism 4 is further provided for timely flushing the surface of the abutment plate 32. The specific structure includes a pressing block 41, a water pressure member 42, a water tank 43, and a nozzle 44, wherein the water tank 43 is filled with a clean water source, one end of the water tank 43 is connected to an external water source through a pipe, and the other end is connected to the nozzle 44, and a one-way valve is installed in the pipe, and the one-way valve here allows the external water source to input water into the water tank 43.

[0032] The water pump can be used to spray water from the nozzle 44 in real time.

[0033] A water pressure piece 42 is elastically and slidably connected to the top of the water tank 43. The end of the water pressure piece 42 located outside the water tank 43 is provided with an inclined surface, and the end located inside the water tank 43 is in close sliding connection with the inner wall of the water tank 43. A pressure block 41 is fixed on the connecting rod 35. The pressure block 41 and the water pressure piece 42 form a wedge block structure. The pressure block 41 squeezes the water pressure piece 42, so that the water pressure piece 42 can press the water flow in the water tank 43 into the nozzle 44 and spray it out through the nozzle 44, so that the nozzle 44 can flush the chips on the resistance plate 32.

[0034] In the present application, the top head 36 and the pressure block 41 are respectively arranged at the two ends of the connecting rod 35. In this way, whenever the cylinder drives the push plate 34 to move back and forth, the push plate 34 will drive the top head 36 and the pressure block 41 to move back and forth through the connecting rod 35, so that the lifting scraper 33 and the squeezing water pressure piece 42 are alternately moved, thereby orderly realizing the functions of scraping off the chips and flushing the contact plate 32.

[0035] In summary, the present application aims to timely remove the chips attached to the resistance plate 32 by using a thrust member to alternately drive the scraper 33 to move up and down and control the nozzle 44 to spray water toward the resistance plate 32, so as to achieve the purpose of cleaning the chips on the resistance plate 32 every time the thrust member moves, thereby improving the practicality of the present solution.

[0036] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
