Description

Technical Field

[0001] The utility model belongs to the technical field of rear axle half-axle production, in particular to a fixing device for producing a tractor rear axle half-axle. Background Art

[0002] The rear axle shaft of a tractor is a crucial component connecting the wheels to the differential, primarily responsible for transmitting torque and rotational motion. It consists of axle tubes, bearings, oil seals, and other components that work together to ensure the stable operation of the rear axle shaft. The function and structure of the rear axle shaft play a key role in tractors, and its design and maintenance are crucial to ensuring the tractor's performance and durability. During the production of the rear axle shaft, holes need to be drilled into the flange. To ensure the hole size and accuracy, a drilling jig is often used during the drilling process. To prevent relative rotation between the drilling jig and the rear axle shaft, the rear axle shaft must first be clamped and secured, and then the drilling jig is pressed and secured. Currently, the drilling jig and rear axle shaft are often secured using a bolted pressure plate structure. However, the actual process consumes considerable auxiliary time for fixing and disassembling, impacting the efficiency of the rear axle shaft drilling process.

[0003] In view of this, the present utility model is proposed. Utility Model Content

A lifting power box 9 is provided below the lifting platform plate 8. The lifting power box 9 is fixedly installed on the main support base plate 1. On the base plate 1, a clamping block 15 and a clamping block 2 18 are symmetrically arranged on both sides below the workpiece placement base 14. The outer sides of the clamping block 15 and the clamping block 2 18 are equipped with a telescopic clamping rod 16. The telescopic clamping rod 16 is fixedly installed on the fixed support 17, and the fixed support 17 is fixedly installed on the main support base plate 1. A rotation matching groove 21 is provided on the upper plane of the rotating support platform 5. A stabilizing support rod 12 is fixedly installed on the bottom surface of the connecting plate 4. The lower end of the stabilizing support rod 12 is rotatably connected to a support roller 13, and the position of the support roller 13 matches the rotation matching groove 21.

[0025] Among them, a limit stopper 6 is fixedly provided on the rotating support platform 5. When the drilling mold 2 is located directly above the workpiece placement base 14, the limit stopper 6 contacts the side of the connecting plate 4 to perform effective limiting.

[0026] A transmission and a rotating motor are provided in the rotating power box 7, and a hydraulic rod 22 is provided in the lifting power box 9. The telescopic end of the hydraulic rod 22 is fixedly connected to the bottom surface of the lifting platform 8. There are four hydraulic rods 22, and the four hydraulic rods 22 rise and fall synchronously.

[0027] A guide hole 23 is provided on the top surface of the lifting power box 9, and a matching sleeve 24 is installed in the guide hole 23. The telescopic rod of the hydraulic rod 22 passes through the center hole of the matching sleeve 24. The clamping surfaces of the clamping block 15 and the clamping block 2 18 are both V-shaped structures, which can effectively center the rear axle half shaft.

[0028] A drill sleeve 3 is installed on the drilling die 2. A matching groove is provided on the bottom surface of the drilling die 2, which is adapted to the size of the flange end of the rear axle half shaft to achieve precise positioning.

[0029] A through hole is opened on the main support base plate 1, and the position of the through hole is located at the center position after the rear axle half-axle is fixed to adapt to the fixing and use requirements of rear axle half-axles of different specifications. Support seats 10 are fixed at the two end positions below the main support base plate 1, and support fixing holes 11 are processed on the support seat 10 for fixed installation of the main support base plate 1.

[0030] The working principle of the utility model is: when the flange of the rear axle half shaft of the tractor is drilled, the drilling die 2 is adjusted to the state where the workpiece placement base 14 is dislocated, as shown in the attached figure. Figure 4 As shown, to avoid interference during the placement of the rear axle half shaft, the shaft end of the rear axle half shaft is placed downward on the workpiece placement platform 14, and the flange end face of the rear axle half shaft contacts the top surface of the workpiece placement platform 14. Under the action of the deadweight of the rear axle half shaft, the contact surface is tightly fitted, and then the two telescopic clamping rods 16 are started. The two telescopic clamping rods 16 move synchronously, driving the clamping and fixing block 15 and the clamping and fixing block 2 18 to move horizontally synchronously to clamp and fix the shaft section of the rear axle half shaft. The clamping surfaces of the clamping and fixing block 15 and the clamping and fixing block 2 18 are both V-shaped surface structures. The centering is automatic during the clamping process to ensure that the center of the workpiece of each clamping of the rear axle half shaft is in the same position. The telescopic clamping rod 16 uses an electric telescopic rod, which is electrically connected to an external power supply.

[0031] Afterwards, the power device in the rotating power box 7 drives the connecting plate 4 to rotate along the rotating power seat 20. A stabilizing support rod 12 and a supporting roller 13 are provided under the connecting plate 4. A rotating matching groove is provided on the rotating support platform 5 to ensure the stability of the rotation process of the connecting plate 4. The connecting plate 4 drives the drilling mold 2 to rotate synchronously. When the drilling mold 2 rotates to the top of the workpiece placement platform 14, the side of the connecting plate 4 contacts the limit block 6 for effective limiting. After that, the hydraulic rod 22 in the lifting power box 9 contracts, driving the lifting platform 8 to move downward, and then driving the drilling mold 2 to move downward. A groove adapted to the rear axle half shaft is provided on the bottom surface of the drilling mold 2, and the slot position is set There is a chamfer structure. During the downward movement of the drilling die 2, it effectively cooperates with the flange end of the rear axle half shaft to complete the installation and fixation of the drilling die 2. The flange end of the rear axle half shaft is drilled using the drilling equipment. The size of the selected drill bit is compatible with the size of the drill sleeve 3. After the basic hole drilling is completed, the hydraulic rod 22 extends to drive the drilling die 2 to separate from the rear axle half shaft product. Then, the drilling die 2 is rotated a certain angle under the drive of the connecting plate 4, and a larger-sized drill bit is replaced to perform hole expansion processing until the drilled hole meets the size requirements of the drawing. After the telescopic clamping rod 16 is retracted, the rear axle half shaft product can be taken out and replaced with a new product to be drilled, and a new processing cycle begins.

[0032] The fixed arrangement of the present invention is provided with a workpiece placement pedestal 14 to support the rear axle half-axle, and is clamped and fixed by a clamping fixing block 15 and a clamping fixing block 2 18 to fix the position of the rear axle half-axle. A connecting plate 4 is fixedly provided on the outside of the drilling mold 2, and a rotating device and a lifting device are provided below the connecting plate 4 to realize the adjustment and fixation of the position of the drilling mold 2. The cooperation and separation operations of the drilling mold 2 and the rear axle half-axle are all automatically controlled, which can effectively reduce labor intensity and shorten the auxiliary time of drilling processing. During the process of the connecting plate 4 driving the drilling mold 2 to rotate, stable support is achieved by the cooperation of the stabilizing support rod 12, the supporting roller 13 and the rotating cooperation slide 21 to ensure the stability of the rotation process.
