Description

Technical Field

[0001] This utility model relates to the field of transmission shaft processing technology, and specifically to a drilling device for transmission shaft processing. Background Technology

[0002] The driveshaft is a high-speed, low-support rotating body, so its dynamic balance is crucial. Generally, driveshafts undergo dynamic balancing tests and adjustments on a balancing machine before leaving the factory. For front-engine, rear-wheel-drive vehicles, the driveshaft transmits the rotation of the transmission to the final drive, and drilling is required on its surface during the manufacturing process.

[0003] Existing drive shaft drilling equipment exhibits circumferential displacement during actual processing: due to the lack of an effective positioning mechanism for the drive shaft under high-speed rotation conditions, the preset drilling position and the drive shaft reference mark are circumferentially offset, directly affecting the coaxiality and positional accuracy of the processed hole, thereby reducing the product qualification rate. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of the existing technology by providing a drilling device for machining a drive shaft that can prevent circumferential displacement of the drive shaft during machining.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a drilling device for processing transmission shafts, including a processing table, the innovation of which is: columns are set at the four corners of the processing table, a mounting plate is set on the top of the columns, and a drilling mechanism is set on the mounting plate; a pair of slide rails are arranged in parallel on the processing table, and at least two sliders are set on each slide rail, and a sliding plate is set on the slider at the same end; a support plate is set in the middle of the sliding plate, and a flexible clamping plate is set on the support plate. The flexible clamping plate has a U-shaped structure. Clamping cylinders are set on the left and right sides of the sliding plate, and clamping plates are set at the piston rod ends of the clamping cylinders. The clamping plates are located on the left and right sides of the flexible clamping plate, and fastening bolts are set on the sliding plate.

[0006] Furthermore, the drilling mechanism includes a lifting cylinder, a mounting bracket is provided on the piston rod of the lifting cylinder, a drilling motor is provided at the bottom of the mounting bracket, and a chuck is provided on the output shaft of the drilling motor, the chuck holding the drill bit.

[0007] Furthermore, the flexible plywood is made of rubber and has raised anti-slip strips on its inner wall.

[0008] Furthermore, the clamping plate has an arc-shaped structure.

[0009] Furthermore, the flexible clamp and the support plate are detachably connected.

[0010] The beneficial effects of this utility model after adopting the above structure are as follows:

[0011] This invention uses at least two flexible clamps to position and fix the drive shaft. The flexible clamps fit the drive shaft under the action of the clamping cylinder, improving the clamping effect and preventing circumferential displacement of the drive shaft, which would affect the drilling position. By setting a sliding plate, the position of the drive shaft can be adjusted to meet the needs of different drilling positions. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0018] See Figure 1-2 A drilling device for machining a drive shaft includes a machining table 1, columns 2 at the four corners of the machining table 1, a mounting plate 3 on the top of the columns 2, and a drilling mechanism 4 on the mounting plate 3; a pair of parallel slide rails 5 are arranged on the machining table 1, and at least two sliders 6 are arranged on each slide rail 5, and a slide plate 7 is arranged on the slider at the same end; a support plate 8 is arranged in the middle of the slide plate 7, and a flexible clamping plate 9 is arranged on the support plate 8. The flexible clamping plate 9 has a U-shaped structure; clamping cylinders 10 are arranged on the left and right sides of the slide plate 7; clamping plates 11 are arranged at the piston rod end of the clamping cylinder 10, and the clamping plates 11 are located on the left and right sides of the flexible clamping plate 9; and fastening bolts 12 are arranged on the slide plate 6. Specifically, the left and right sides of the drive shaft are placed in the flexible clamping plates 9 respectively. The clamping cylinder 10 is activated, and the clamping plate 11 applies force to the flexible clamping plates 9 to clamp the drive shaft, preventing circumferential displacement of the drive shaft and affecting the drilling position. Then, the drilling operation is performed by the drilling mechanism 4. If the drilling position needs to be adjusted, the drive shaft can be moved laterally by the slide plate 7, slide rail 5 and slider 6. After the position is adjusted, the position can be locked by the fastening bolts, and the drilling operation can then be performed.

[0019] In this embodiment, the drilling mechanism 4 includes a lifting cylinder 41. A mounting bracket 42 is provided on the piston rod of the lifting cylinder 41, and a drilling motor 43 is provided at the bottom of the mounting bracket 42. A chuck 44 is provided on the output shaft of the drilling motor 43, and the chuck 44 holds the drill bit 45. After the drilling motor 43 is started, it drives the drill bit 45 to rotate and move downward under the action of the lifting cylinder 41, thus drilling a hole in the outer surface of the drive shaft.

[0020] In this embodiment, the flexible clamp 9 is made of rubber, and its inner wall is provided with raised anti-slip strips 13. The anti-slip strips 13 are used to increase the friction with the drive shaft, which is beneficial for clamping and fixing.

[0021] In this embodiment, the clamping plate 11 has an arc-shaped structure. During the clamping process, the arc-shaped clamping plate 11 can make the flexible clamping plate 9 fit more closely to the surface of the drive shaft when it is squeezed, which is beneficial for clamping and fixing.

[0022] In this embodiment, the flexible clamping plate 9 and the support plate 8 are detachably connected. Bolts are used for fixing the connection, facilitating the installation and removal of the flexible clamping plate 9, and allowing for replacement after breakage and the selection of a suitable flexible clamping plate 9 according to different specifications of the drive shaft.

[0023] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
