The above-mentioned drilling machine can only realize a single hole opening, and it is necessary to change the orientation of the plate-like automobile parts multiple times to realize the action of opening a plurality of through holes, and the hole opening efficiency is low. Summary of the invention

[0005] In order to solve the above problems, the present invention provides an adjustable drilling machine for processing automobile parts.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: an adjustable drilling machine for processing automobile parts, comprising a mounting frame, a base plate arranged on one side of the mounting frame and a vertical plate fixed on the top of the base plate, the mounting frame is provided with clamping components on both sides for fixing the plate-like automobile parts to be punched, a mounting plate is provided on the vertical plate, a hollow sleeve rotatably connected to the mounting plate is penetrated through the mounting plate, a plurality of the hollow sleeves are provided and distributed in a straight line, a drill bit is provided at the lower end of each of the hollow sleeves, a rotating component for driving the plurality of hollow sleeves to rotate synchronously is provided on the mounting plate, and a control component for individually controlling the descent of the drill bit is provided on each of the hollow sleeves.

[0007] By adopting the above technical solution, the staff can control the descent of the drill bit required for drilling through the control component, and the rotating component can drive multiple hollow casings to rotate synchronously at the same time, so that multiple drill bits can rotate synchronously and open multiple through holes on plate-like automotive parts, which changes the structural design of traditional drilling machines and improves the hole opening efficiency.

[0008] Furthermore, the control component includes a tube body fixed and connected to the upper end of the hollow sleeve, an inner piston slidingly matched with the inner wall of the hollow sleeve, a spring fixed between the top of the inner piston and the inner top wall of the hollow sleeve, a connecting rod fixed to the bottom of the inner piston, and a limit rod fixed to the bottom of the hollow sleeve. The tube body is connected to an external high-pressure inflation system through a connecting pipe, and the tube body and the connecting pipe are connected and sealed by a rotating shaft seal. The upper end of the drill bit is connected to the lower end of the connecting rod, and the connecting rod is penetrated by a vertical limit groove for the limit rod to slide with.

[0009] By adopting the above technical solution, the staff can fill the hollow casing with high pressure through the external high-pressure inflation system, so that the inner piston can move downward, thereby causing the connecting rod and the drill bit to move downward. The limit rod cooperates with the vertical limit groove to ensure that the connecting rod rotates synchronously with the hollow casing. After the control component controls the rotation of multiple hollow casings, the drill bit can rotate and complete the hole-opening action.

[0010] Furthermore, the rotating assembly includes an upper motor fixed on a mounting frame, a driving gear fixed to the lower end of an output shaft of the upper motor, and a driven gear fixedly sleeved on a hollow sleeve and meshing with the driving gear, wherein the driven gear is coaxially arranged with the hollow sleeve, and the number of the driven gears is equal to the number of the hollow sleeves and their positions correspond one to one.

[0011] By adopting the above technical solution, the upper motor drives the driving gear to rotate after it starts working, so that the driven gear meshing with the driving gear and the hollow sleeve fixed to the driven gear both rotate, thereby causing the drill bit to rotate. The drill bit driven down by the external high-pressure inflation system can perform a hole opening operation on a plate-shaped automobile part.

[0012] Furthermore, the mounting plate includes a U-shaped plate section that penetrates and slides through the vertical plate and a connecting plate section fixed between the plate bodies on both sides of the U-shaped plate section. An electric push rod is fixed on the vertical plate, and the output end of the electric push rod is fixed to one side of the connecting plate section close to the vertical plate.

[0013] By adopting the above technical solution, the electric push rod drives the connecting plate section and the U-shaped plate section to move after working, so as to control the position of the mounting plate in the length direction of the mounting frame, thereby adjusting the position of the drill bit so as to perform hole opening actions at different positions on the plate-shaped automobile parts.

[0014] Furthermore, a side connecting plate is fixed on the mounting frame, a U-shaped plate body is arranged above the side connecting plate, a vertical plate is fixed on the middle section of the U-shaped plate body, and a fixing assembly for fixing the U-shaped plate body is arranged on the side connecting plate, and the clamping assembly includes a lower motor fixed on the vertical plate, a worm fixed to the output end of the lower motor, a rotating rod rotatably installed between the plates on both sides of the U-shaped plate body, a pressing plate fixedly mounted on the rotating rod, and a worm wheel fixedly mounted on the rotating rod and meshing with the worm.

[0015] By adopting the above technical solution, the lower motor drives the worm to rotate after working, so that the worm wheel meshing with the worm, the rotating rod fixed to the worm wheel and the pressure plate fixed to the rotating rod rotate, so that the pressure plate presses and fixes the plate-like automobile parts, which is beneficial to the hole opening processing of the plate-like automobile parts.

[0016] Furthermore, the fixing assembly includes a connecting shaft fixed to the bottom of the middle section of the U-shaped plate body and a nut sleeved on the connecting shaft and threadedly connected to the connecting shaft. The connecting shaft passes through the side connecting plate and is clearance-fitted. Two nuts are provided and are symmetrically arranged up and down about the side connecting plate.

[0017] By adopting the above technical solution, after loosening the nut, the U-shaped plate body can be moved up and down, thereby adjusting the height of the pressing plate, so that the pressing plate can press and fix plate-shaped automobile parts of different thicknesses after being adjusted to a horizontal state.

[0018] Furthermore, a rubber pad is sleeved on the connecting shaft and is located between the nut and the side connecting plate, and two rubber pads are provided.

[0019] By adopting the above technical solution, the friction damage to the opposite side connecting plate during the process of screwing the nut is reduced.

[0020] Furthermore, a pressure relief valve is provided at the upper end of the hollow sleeve.

[0021] By adopting the above technical solution and setting the pressure relief valve, it is convenient to perform pressure relief operation on the hollow casing, so as to drive the drill bit to reset after the hole is opened, so as to remove the plate-shaped automobile parts after the hole is opened.

[0022] Furthermore, a fixing block is fixed on the top of the mounting frame, and two fixing blocks are symmetrically arranged. A clamping assembly is provided on the vertical plate for cooperating with the fixing block and clamping against the plate-like automobile parts to be punched.
