Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, and in particular to a drilling device for automotive parts production. Background Technology

[0002] In the automobile manufacturing process, drilling is required on components. For example, drilling holes in the automobile frame mainly serves to reduce weight, facilitate heat dissipation and ventilation, increase rigidity, and facilitate processing and assembly. Drilling holes in other components can be used for connecting and fixing components, and for laying cables.

[0003] Large drilling equipment has a relatively heavy drive structure, meaning that components such as the drive motor and the drill bit connected to the output end of the drive motor are large in size and weight. A gantry structure is generally used to ensure the reliability of its support. Since it is supported on both sides and performs lifting and lowering movements, it is necessary to keep the lifting structure horizontal during the lifting process, that is, to ensure the verticality of the drill bit. As the drill bit approaches the workpiece, its posture remains unchanged, thus ensuring the quality of drilling. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a drilling device for automotive parts production, comprising a base plate, a lifting plate disposed above the base plate, a drive motor fixedly connected to the upper center of the lifting plate, an output end extending downward from the drive motor, and a drill bit fixedly connected to the output end. Starting the drive motor drives the drill bit to rotate.

[0005] Both ends of the lifting plate are fixedly connected to cylinders, and the two cylinders are arranged in parallel. Each cylinder extends downwards with a telescopic rod, the lower end of which is fixedly connected to the upper end of the base plate. The cylinder fixture allows the telescopic rod to extend or retract, thus raising and lowering the lifting plate. When the telescopic rod retracts, the drill bit approaches the workpiece for drilling. Furthermore, the parallel arrangement of the two cylinders ensures that the lifting plate can move horizontally during the lifting process.

[0006] Preferably, guide rods are fixedly connected to both sides of the base plate, and the lifting plate slides on the guide rods. A total of four guide rods are provided to ensure that the lifting plate can rise and fall stably.

[0007] Preferably, a convex ring is fixedly connected to the lower side wall of the guide rod, and a fixing nut is provided at the lower part of the guide rod, with the base plate clamped between the convex ring and the fixing nut. The guide rod is fixedly connected to the base plate by the fixing nut and the convex ring.

[0008] Preferably, the lower end of the lifting plate is provided with several ribs. The ribs are used to improve the structural strength of the lifting plate.

[0009] Preferably, an air compressor and an air tank are fixedly connected to the lower end of the base plate. The air compressor and air tank provide the air source for the cylinder.

[0010] Preferably, each of the four lower corners of the base plate is fixedly connected to a base plate, the base plate including a cross plate, and the upper and lower ends of the cross plate being fixedly connected to mounting plates. The mounting plates are provided with several connection holes. The base and the base plate are fixedly connected by bolts passing through the connection holes.

[0011] Preferably, fixing bolts are inserted on both sides of the base plate, and the fixing bolts are threadedly connected to the lower part of the telescopic rod. The end of the telescopic rod is fixedly connected to the base plate by the fixing bolts.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. It is equipped with cylinders, and two cylinders are connected in parallel. Together with the guide rod, it ensures that the lifting plate can be raised and lowered horizontally, which helps to ensure the drilling quality.

[0014] 2. It is equipped with a base, which includes mounting plates on the top and bottom to support and lift the base plate, preventing the drill bit from contacting the support surface after passing through the workpiece. Attached Figure Description

[0022] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0023] like Figures 1 to 4 As shown, a drilling device for automotive parts production includes a base plate 2, which is located on a rectangular plate. A lifting plate 5 is arranged above the base plate 2. A drive motor 8 is fixedly connected to the upper middle part of the lifting plate 5. A flange structure is provided at the lower end of the drive motor 8 and is fixedly connected to the lifting plate 5 by bolts. An output end is provided extending downward from the drive motor 8, and a drill bit 6 is fixedly connected to the output end. Furthermore, a connecting piece is provided between the output end and the drill bit 6. When the drive motor 8 is energized, the drill bit 6 rotates.

[0024] Both ends of the lifting plate 5 are fixedly connected to cylinders 7, and the two cylinders 7 are arranged in parallel. That is, when the two cylinders 7 are working, their internal air chambers are connected and the air pressure is consistent. The cylinders 7 extend downward to form a telescopic rod 4. When the two cylinders 7 are connected in parallel and working, the extension and retraction length of the telescopic rod 4 is consistent, which ensures that the lifting plate 5 can maintain horizontal lifting and lowering. The lower end of the telescopic rod 4 is fixedly connected to the upper end of the base plate 2. Note that a through hole is provided in the middle of the base plate 2. The through hole is located directly below the drill bit 6. When the cylinders 7 are working, the telescopic rod 4 retracts, and at this time the drill bit 6 moves closer to the workpiece.

[0025] Guide rods 3 are fixedly connected to both sides of the base plate 2. The guide rods 3 are bare rods, and a total of four are provided. The lifting plate 5 slides on the guide rods 3 to ensure that the lifting plate 5 moves up and down smoothly.

[0026] A protruding ring 14 is fixedly connected to the lower side wall of the guide rod 3. A fixing nut 12 is provided at the lower part of the guide rod 3, and the base plate 2 is clamped between the protruding ring 14 and the fixing nut 12. In addition, a through hole is provided on the base plate 2, and the lower end of the guide rod 3 is inserted into the through hole. Then, the fixing bolt 12 is installed to fix the guide rod 3.

[0027] The lower end of the lifting plate 5 is provided with several ribs 11. The ribs 11 are used to improve the structural strength of the lifting plate 5.

[0028] An air compressor 9 and an air tank 10 are fixedly connected to the lower end of the base plate 2. When the air compressor 9 operates, it pumps air into the air tank 10, which is connected to the cylinder 7 via an air pipe.

[0029] The base plate 2 is fixedly connected to the four corners of the lower end of the base plate 2. The base plate 1 is set to raise the base plate 2 to prevent the drill bit 6 from contacting the support surface. In addition, it is used to accommodate the air compressor 9 and the air tank 10. The base plate 1 includes a cross plate 102. The upper and lower ends of the cross plate 102 are fixedly connected to the mounting plate 101. The mounting plate 101 is provided with several connection holes 103. Bolts are used to pass through the connection holes 103. In addition, the base plate 2 is also provided with through holes. Therefore, the base 1 is fixedly connected to the lower end of the base plate 2 by bolts.

[0030] Fixing bolts 13 are inserted on both sides of the base plate 2, and the fixing bolts 13 are threadedly connected to the lower part of the telescopic rod 4. That is, the telescopic rod 4 is fixedly connected to the upper end of the base plate 2 by fixing bolts 13.
