Steel processing device for manufacturing automobile half-axles

Abstract

The present invention belongs to the technical field of steel processing, and discloses a steel processing device for manufacturing automobile half-axles, comprising a base, a rotating mechanism fixedly connected to the left side of the base, a clamping mechanism transmission-connected to the middle right side of the rotating mechanism, two large screws rotatably connected to the bottom end of the rotating mechanism, and a driving mechanism transmission-connected to the right end of the large screw. The present invention pushes the sliding tool holder and the drilling tool to be exposed on the left side of the annular body. When the drilling tool contacts the half-axle steel, a through hole is slowly drilled in the half-axle steel, and a grinding roller grinds the drilled through hole to remove burrs on the inner wall of the through hole and make it smooth to meet production requirements, thereby solving the problem that a large amount of burrs are generated when drilling with drilling equipment, and the burrs need to be polished later. Then, the existing half-axle production equipment does not have a device that integrates drilling and polishing, and needs to be processed separately and transported, which is cumbersome to produce and process.

Description

Technical Field

[0001] The invention belongs to the technical field of steel processing, and in particular relates to a steel processing device for manufacturing automobile half-axles. Background Art

[0002] Axle shafts are crucial components in a vehicle's drivetrain, responsible for transferring power from the differential to the wheels. Because they transmit torque and withstand various forces during vehicle operation, they must meet stringent standards and requirements during their design and manufacturing.

[0003] During the production and processing of existing half-axles, cutting, polishing and grinding processes are required. In some cases, a through hole of appropriate size needs to be drilled at the right end of the half-axle. However, existing drilling equipment will produce a large number of burrs when drilling, which need to be polished later. In addition, existing half-axle production equipment does not integrate drilling and polishing into one device, so they need to be processed separately and transported, which makes production and processing more cumbersome. The same problem also occurs in cutting and polishing. Therefore, there is an urgent need for a multifunctional production and processing lathe dedicated to automobile half-axle manufacturing to meet the mechanical processing required by the half-axle as well as other metal processing such as polishing and grinding.

The control valve assembly 20 is in a state of connecting the main liquid channel 24 with the oil inlet pipe, and the two T-shaped channels 22 are closed. The existing cutting fluid supply pipe supplies cutting fluid to the inside of the cutting fluid channel 19, and the half-shaft steel rotates, so that the cutting fluid is smeared on the right side of the half-shaft steel. Then the hydraulic oil enters the main liquid channel 24 and the L liquid channel 25, and finally enters the right side of the cylindrical cavity 26, thereby causing the push plate 27 to move to the left and squeeze the compression spring 30, so that the grinding plate 29 deburrs and polishes the right side of the half-shaft steel.

[0026] Working principle:

[0027] Before the present invention is used, the existing cutting fluid supply pipe is connected to the cutting fluid channel 19, and the oil inlet pipe and oil return pipe of the existing hydraulic supply device are connected to the two connecting pipes 21;

[0028] Before using the present invention, the half-axle steel to be processed is fixed by the clamping mechanism 3, the control valve assembly 20 is in a state where the front main fluid channel 24 is closed, the rear T-shaped channel 22 is connected to the oil inlet pipe, and the front T-shaped channel 22 is connected to the oil return pipe. The two distribution valves 31 are connected to the oil inlet pipe and the upper sliding chamber 23, and the lower sliding chamber 23 is closed. The hydraulic oil enters the inner rear of the upper T-shaped channel 22, thereby pushing the sliding tool holder 16 and the drilling tool 17 to be exposed on the left side of the annular body 7. When the drilling tool 17 is fully exposed, The distribution valve 31 is in a state where the upper and lower sliding chambers 23 are closed. The second motor 12 is working, driving the driving gear 13 to rotate. The driving gear 13 drives the upper and lower meshing driven gears 14 to rotate. The driven gear 14 rotates to rotate the rotating shaft 15. The rotating shaft 15 rotates to drive the upper drilling tool 17 and the lower grinding roller 18 to rotate. Then the driving mechanism 5 is working, driving the large screw 4 to rotate, thereby moving the driving mechanism 5 to the left. When the exposed drilling tool 17 contacts the half-shaft steel, it slowly drills a through hole in the half-shaft steel.

[0029] Then the driving mechanism 5 drives the drilling tool 17 to move to the right, and the rotating mechanism 2 drives the half-axle steel to rotate 180 degrees. The two distribution valves 31 are connected with the oil inlet pipe and the lower sliding chamber 23, and the upper sliding chamber 23 is closed, so that the grinding roller 18 is exposed to the annular body 7. When the driving mechanism 5 drives the drilling tool 17 and the grinding roller 18 to move to the left, the drilling tool 17 will drill a new through hole, and the grinding roller 18 grinds the drilled through hole to remove the burrs on the inner wall of the through hole and make it smooth to meet the production requirements. Then the rotating mechanism 2 drives the half-axle steel to rotate 180 degrees, so that the grinding roller 18 is exposed to the annular body 7. The through hole on the opposite side of the roller 18 is ground. After the grinding is completed, the control valve assembly 20 is in a state where the front main liquid channel 24 is closed, the front T-shaped channel 22 is connected to the oil inlet pipe, and the rear T-shaped channel 22 is connected to the oil return pipe. The two distribution valves 31 are connected with the oil inlet pipe and the lower sliding chamber 23, and the upper sliding chamber 23 is closed. Hydraulic oil enters, thereby making the grinding roller 18 hidden in the interior of the annular body 7. Subsequently, the rotating mechanism 2 drives the half-shaft steel to rotate a certain angle, so that the drilling tool 17 drills the half-shaft steel. When drilling the through hole on the opposite side, the grinding roller 18 is exposed, and the through hole is ground until the drilling process of the half-shaft steel is completed.

[0030] When drilling and cutting the half-shaft steel, when the cutting tool 11 approaches the right side of the half-shaft steel, the driving mechanism 5 stops working, and the rotating mechanism 2 drives the clamping mechanism 3 and the half-shaft steel to rotate. Then the motor 18 starts working, driving the small screw 9 to rotate and causing the cutting tool holder 10 to slide in the sliding groove, thereby changing the cutting position of the cutting tool 11 on the half-shaft steel. Through the mutual cooperation of the driving mechanism 5 and the motor 18, the right end of the half-shaft steel is processed to the target size;

[0031] After the processing is completed, the cutting seat 10 and the cutting tool 11 move to the front end, the right side of the half-shaft steel is fitted with the left side of the annular main body 7, the control valve assembly 20 is in a state where the main liquid channel 24 is connected to the oil inlet pipe, and the two T-shaped channels 22 are closed. The existing cutting fluid supply pipe supplies cutting fluid to the inside of the cutting fluid channel 19, and the half-shaft steel rotates so that the cutting fluid is smeared on the right side of the half-shaft steel. Then the hydraulic oil enters the main liquid channel 24 and the L liquid channel 25, and finally enters the right side of the cylindrical cavity 26, thereby moving the push plate 27 to the left and squeezing the compression spring 30, so that the grinding plate 29 deburrs and polishes the right side of the half-shaft steel. After grinding is completed, the main liquid channel 24 is connected to the return oil pipe, and the compression spring 30 pushes the push plate 27 to reset.
