Description

Technical Field

[0001] This invention relates to the field of automotive parts processing equipment technology, specifically to a steering gear inner tube column flange device. Background Technology

[0002] The steering column inner tube is a key component of a car's steering system, typically located inside the steering column, serving as a rigid sleeve structure connecting the steering wheel and the steering mechanism. Its core function is to protect and guide the movement of the steering drive shaft (such as a universal joint or intermediate shaft), ensuring that the rotational force input from the steering wheel is efficiently transmitted to the steering gear or steering mechanism, while providing a stable support frame for the steering column to withstand torque and vibration during driving.

[0003] In the machining process of the steering gear inner tube column, diameter expansion and flanging are two key processes that directly affect its assembly accuracy and connection strength with the steering shaft. First, the inner tube column end needs to be expanded by using a diameter expansion machine to increase the diameter of the tube opening to ensure that the steering shaft can be smoothly inserted and avoid interference during assembly. Then, the expanded end is flanged using a flanging machine. Flanging increases the contact area at the end of the inner tube column. When the inner tube column is welded to the universal joint of the cross shaft, the flanging structure improves the load-bearing capacity of the weld, enabling the connection part to withstand greater torque and vibration loads during vehicle operation.

[0004] The existing steering gear inner tube column machining equipment has gradually revealed its shortcomings during use, mainly in the following aspects: The inner tube column's diameter expansion and flanging process suffers from poor continuity. Specifically, the diameter expansion and flanging process first relies on a diameter expansion machine to enlarge the end. After completion, the workpiece needs to be disassembled and transferred to the flanging station for secondary clamping. In the flanging process, to avoid uneven thickness and angle deviation, a step-by-step processing procedure is adopted: first, a conical mandrel is used to expand the end of the inner tube column into a trumpet shape; after the mandrel is removed, a flattening roller is inserted for spinning and flattening. Based on this, a deeper analysis reveals that the discrete processing mode with multiple equipment switching, and the serial processing mode of the conical mandrel and flattening roller, result in two significant production interruptions in the entire processing flow—the first occurring during the material transfer stage between the diameter expansion and flanging processes, and the second occurring during the tool change within the flanging process itself. This leads to poor continuity in the inner tube column's diameter expansion and flanging process, severely impacting processing efficiency.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a steering gear inner tube column flange device. This device achieves integrated continuous processing of inner tube column diameter expansion, flaring, and spinning leveling through integrated design. The inner tube column can be formed in one operation, completely eliminating the processing interruption caused by equipment switching and step-by-step operation in traditional processes. This significantly improves processing continuity, reduces accuracy errors caused by repeated workpiece positioning, and greatly shortens the processing cycle.

[0007] To address the above problems, the present invention provides the following technical solution: A steering gear inner tube column flange device includes an operating table. The top of the operating table has a horizontally sliding L-shaped plate and two detachably fixed L-shaped plates. The top of the sliding L-shaped plate is detachably equipped with a mounting plate. A rotating shaft is rotatably connected to the end of each mounting plate. A fixed shaft is fixedly connected to the end of each sliding L-shaped plate. One end of the fixed shaft passes through the rotating shaft and is fixedly connected to an expanding mandrel. The rotating shaft is rotatably connected to the fixed shaft and is in frictional contact with the expanding mandrel. The front and rear ends of the expanding mandrel are respectively the expanding region and the pre-flaring region. The front end of the rotating shaft is the post-flaring region. The flaring area consists of a pre-flaring area and a post-flaring area. The outer wall of the rotating shaft is provided with several mounting grooves along the circumference. A movable block is provided in the mounting groove and moves radially along the rotating shaft. The top of the movable block is conformally arranged with the post-flaring area of ​​the rotating shaft. The movable block is in frictional contact with the rotating shaft and the expansion mandrel. An upper clamping plate is provided between the two fixed L-shaped plates and is detachably connected to them. A lower clamping plate is provided vertically at the bottom of the upper clamping plate. A slider is provided vertically at the ends of the upper and lower clamping plates. An expansion groove is provided at the bottom of the upper clamping plate and the top of the lower clamping plate. A flaring groove is provided on both sliders.

[0008] As an optimized solution, a sliding plate is horizontally slidably provided in the mounting groove, an active wedge block is detachably provided at the end of the sliding plate, and a passive wedge block is detachably provided at the end of the moving block, with the inclined end of the active wedge block and the inclined end of the passive wedge block slidably connected.

[0009] As an optimized solution, an electrically controlled telescopic cylinder is fixedly installed in the mounting groove, and the telescopic end of the electrically controlled telescopic cylinder is fixedly connected to the sliding plate.

[0010] As an optimized solution, a fixed cylinder is fixedly provided at the end of the rotating shaft. The fixed shaft is located inside the fixed cylinder and is rotatably connected to the fixed cylinder. A conductive slip ring is fitted on the outer wall of the fixed cylinder. The conductive slip ring is detachably connected to the sliding L-shaped plate. The electrically controlled telescopic cylinder is electrically connected to an external power source through the conductive slip ring.

[0011] As an optimized solution, a number of fixing rods are fixedly provided at the bottom of the mounting groove, and the fixing rods extend into the movable block and are slidably connected to the movable block.

[0012] As an optimized solution, the end of the mounting plate is provided with a drive shaft, and the outer walls of both the drive shaft and the rotating shaft are fixedly fitted with sprockets. The two sprockets are connected by a chain. The end of the mounting plate is fixedly provided with a drive motor, and the output shaft of the drive motor is fixedly connected to the drive shaft.

[0013] As an optimized solution, a drive telescopic cylinder is fixedly installed on the top of the operating table, and the telescopic end of the drive telescopic cylinder is fixedly connected to the sliding L-shaped plate.

[0014] As an optimized solution, the top of the operating table is detachably equipped with several support rods, which pass through the lower clamping plate and are slidably connected to it. The bottom of the operating table is fixedly equipped with a lifting telescopic cylinder, the telescopic end of which passes through the operating table and is fixedly connected to the lower clamping plate.

[0015] As an optimized solution, the top of the upper clamping plate and the bottom of the lower clamping plate are both fixedly provided with supporting L-shaped plates, and the end of the supporting L-shaped plates is vertically slidably provided with lifting plates. The slider is detachably connected to the lifting plates, and the top of the operating table is provided with a clearance groove.

[0016] As an optimized solution, each of the supporting L-shaped plates is fixedly equipped with a control telescopic cylinder, and the telescopic end of the control telescopic cylinder is fixedly connected to the lifting plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. Place the inner tube column to be processed into the expansion groove of the lower clamping plate. The lifting and telescopic cylinder drives the lower clamping plate to slide upward until it abuts against the upper clamping plate. At this time, the inner tube column is clamped (e.g., Figure 8 As shown), the telescopic cylinder drives the sliding L-shaped plate to slide closer to the inner tube column. When the expansion area of ​​the expansion mandrel is inserted into the inner tube column, it expands the diameter of the inner tube column. As the sliding L-shaped plate slides, the expansion mandrel is continuously inserted into the inner tube column. When the flaring area is inserted into the inner tube column, the expanded end of the inner tube column is flared. After the inner tube column is flared (as shown), the flaring is completed (e.g., Figure 9 As shown), at this time, the expansion process of the inner tube column is completed simultaneously. The control telescopic cylinder drives the lifting plate and the slider to slide vertically. The two sliders separate and avoid each other, and the flared end of the inner tube column is exposed. Then, the drive motor drives the sprocket, chain and rotating shaft to rotate. During the rotation of the rotating shaft, the electric control telescopic cylinder drives the sliding plate and the active wedge block to move towards the moving block. With the cooperation of the passive wedge block, the moving block slides outward, thereby spinning the exposed flared end of the inner tube column until the flared end of the inner tube column is flattened (as shown). Figure 10As shown in the figure, the lifting telescopic cylinder drives the lower clamping plate to move downward and reset, and then the processed inner tube column is taken out, thus completing the processing of the inner tube column. This device realizes the integrated continuous processing of inner tube column diameter expansion, flaring and spinning leveling through integrated design. The inner tube column can be processed into shape in one go, completely eliminating the processing interruption problem caused by equipment switching and step-by-step operation in traditional process, significantly improving the processing continuity, reducing the accuracy error caused by repeated workpiece positioning, and greatly shortening the processing cycle. 2. The flaring area and the flaring back area that make up the flaring region are located at the rear end of the flaring mandrel and the front end of the rotating shaft, respectively. When the moving block is spun and pressed on the flaring port of the inner tube, the inner tube bends at the flaring front area to form a bend. 3. When the inner tube column port is flared, the two sliders are in contact and can restrict the outer wall of the inner tube column port, effectively preventing the problem of uneven port thickness and angle deviation after the inner tube column is flared. When the moving block spins the inner tube column port, the two sliders separate and thus avoid the moving block, improving the practicality of the device. 4. When the rotating shaft is rotating, the conductive slip ring can ensure that the electric telescopic cylinder is continuously energized and prevent the cable from getting tangled.

[0021] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings.

[0023] A sliding plate 22 is horizontally slidably provided in the mounting groove 20. An active wedge block 23 is detachably provided at the end of the sliding plate 22, and a passive wedge block 24 is detachably provided at the end of the moving block 21. The inclined end of the active wedge block 23 is slidably connected to the inclined end of the passive wedge block 24.

[0024] An electrically controlled telescopic cylinder 19 is fixedly installed inside the mounting slot 20, and the telescopic end of the electrically controlled telescopic cylinder 19 is fixedly connected to the sliding plate 22.

[0025] A fixed cylinder 7 is fixedly provided at the end of the rotating shaft 13. The fixed shaft 8 is located inside the fixed cylinder 7 and is rotatably connected to the fixed cylinder 7. A conductive slip ring 9 is fitted on the outer wall of the fixed cylinder 7. The conductive slip ring 9 is detachably connected to the sliding L-shaped plate 3. The electrically controlled telescopic cylinder 19 is electrically connected to an external power source through the conductive slip ring 9.

[0026] Several fixing rods 25 are fixedly provided at the bottom of the mounting groove 20. The fixing rods 25 extend into the movable block 21 and are slidably connected to the movable block 21.

[0027] The mounting plate 5 has a drive shaft 10 rotatably mounted at its end. Both the drive shaft 10 and the rotating shaft 13 have sprockets 11 fixedly mounted on their outer walls. The two sprockets 11 are connected by a chain 4. The mounting plate 5 has a drive motor 12 fixedly mounted at its end. The output shaft of the drive motor 12 is fixedly connected to the drive shaft 10.

[0028] A drive telescopic cylinder 2 is fixedly installed on the top of the operating table 1, and the telescopic end of the drive telescopic cylinder 2 is fixedly connected to the sliding L-shaped plate 3.

[0029] The top of the operating table 1 is detachably equipped with several support rods 37, which pass through the lower clamping plate 32 and are slidably connected to the lower clamping plate 32. The bottom of the operating table 1 is fixedly equipped with a lifting telescopic cylinder 36, the telescopic end of which passes through the operating table 1 and is fixedly connected to the lower clamping plate 32.

[0030] The top of the upper clamping plate 31 and the bottom of the lower clamping plate 32 are both fixedly provided with supporting L-shaped plates 29. The end of the supporting L-shaped plates 29 is vertically slidably provided with lifting plates 28. The slider 27 is detachably connected to the lifting plates 28. The top of the operating table 1 is provided with a clearance groove 35.

[0031] Each L-shaped support plate 29 is fixedly equipped with a control telescopic cylinder 30, and the telescopic end of the control telescopic cylinder 30 is fixedly connected to the lifting plate 28.

[0032] The working principle of this device is as follows: The inner tube column 26 to be processed is placed in the expansion groove 34 of the lower clamping plate 32. The lifting and telescopic cylinder 36 drives the lower clamping plate 32 to slide upward until it abuts against the upper clamping plate 31. At this time, the inner tube column 26 is clamped (e.g., Figure 8 As shown), the telescopic cylinder 2 drives the sliding L-shaped plate 3 to slide towards the inner tube column 26. When the expansion area 16 of the expansion mandrel 15 is inserted into the inner tube column 26, the inner tube column 26 is expanded. As the sliding L-shaped plate 3 slides, the expansion mandrel 15 is continuously inserted into the inner tube column 26. When the flaring area 14 is inserted into the inner tube column 26, the expanded end of the inner tube column 26 is flared. After the inner tube column 26 is flared (as shown), the inner tube column 26 is flared (as shown). Figure 9 As shown), at this time, the expansion process of the inner tube column 26 is completed simultaneously. The control telescopic cylinder 30 drives the lifting plate 28 and the slider 27 to slide vertically. The two sliders 27 separate and avoid each other, and the flared port of the inner tube column 26 is exposed. Then, the drive motor 12 drives the sprocket 11, chain 4 and rotating shaft 13 to rotate. During the rotation of the rotating shaft 13, the electric control telescopic cylinder 19 drives the sliding plate 22 and the active wedge block 23 to move towards the moving block 21. With the cooperation of the passive wedge block 24, the moving block 21 slides outward, thereby spinning the exposed flared port of the inner tube column 26 until the flared port of the inner tube column 26 is flattened (as shown). Figure 10As shown), the lifting telescopic cylinder 36 drives the lower clamping plate 32 to move downward and reset, and then the processed inner tube column 26 is taken out, thus completing the processing of the inner tube column 26. This device realizes the integrated continuous processing of inner tube column 26 through integrated design, including diameter expansion, flaring and spinning leveling. The inner tube column 26 can be processed into shape in one go, completely eliminating the processing interruption problem caused by equipment switching and step-by-step operation in traditional processes, significantly improving processing continuity, reducing the accuracy error caused by repeated workpiece positioning, and greatly shortening the processing cycle. The flaring area 14 consists of the flaring front area 17 and the flaring rear area 18, which are located at the rear end of the expanding mandrel 15 and the front end of the rotating shaft 13, respectively. When the moving block 21 is rotating and pressing the flaring port of the inner tube column 26, the inner tube column 26 bends at the flaring front area 17 to form a bend. When the inner tube column 26 port is flared, the two sliders 27 are in a close-fitting state. The two sliders 27 can restrict the outer wall of the inner tube column 26 port, effectively preventing the problem of uneven port thickness and angle deviation after the inner tube column 26 is flared. When the moving block 21 spins the flared port of the inner tube column 26, the two sliders 27 separate and thus avoid the moving block 21, improving the practicality of the device. When the rotating shaft 13 is rotating, the conductive slip ring 9 can ensure that the electrically controlled telescopic cylinder 19 is continuously energized and prevent the cable from getting tangled.
