Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a half-shaft straightening device. Background Technology

[0002] In the automotive manufacturing and related industries, the half-shaft is an indispensable key component of the transmission system. Its quality and precision play a crucial role in the vehicle's driving stability, handling, and safety. During the manufacturing process, the half-shaft may experience varying degrees of bending deformation due to various factors, thus requiring straightening treatment.

[0003] Traditional half-shaft straightening equipment has many limitations in structure and function. On the one hand, traditional equipment performs poorly in terms of straightening accuracy, making it difficult to meet the high-precision straightening requirements of the modern automotive manufacturing industry for half-shafts. Due to the lack of precise curvature detection devices and efficient straightening actuators, it is impossible to accurately locate and straighten the curvature of the half-shaft, resulting in the possibility that the straightened half-shaft may still have some curvature error, affecting its performance.

[0004] On the other hand, the straightening efficiency of traditional equipment is not high enough. The straightening process often requires frequent manual intervention, which is cumbersome. In addition, the equipment has a low degree of automation and cannot achieve fast and continuous straightening operations, which seriously restricts the improvement of production efficiency.

[0005] To address the aforementioned problems, this utility model document proposes a half-shaft straightening device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing half-shaft straightening equipment, such as poor straightening accuracy, low efficiency, frequent manual intervention, and easy impact on work efficiency. Therefore, this invention proposes a half-shaft straightening device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A half-shaft straightening device, comprising:

[0009] The processing base includes a processing seat and two staggered conveyor frames, which are located on both sides of the processing seat. The processing seat includes a processing base, a top bracket fixed to the top of the processing base, a straightening component, a support component, and a fixing component.

[0010] The straightening assembly includes a movable seat slidably mounted on the top support, a straightening cylinder fixed to the bottom of the movable seat, and a top pressure block located at the end of the piston rod of the straightening cylinder.

[0011] The support assembly includes two first abutting parts and a plurality of second abutting parts disposed therebetween. The first abutting part includes a first support seat driven by a first cylinder and two rollers. The second abutting part includes a second support seat driven by a second cylinder.

[0012] The fixing component includes a liftable driving wheel and a driven wheel, which are respectively located at both ends of the support component;

[0013] The machining base is also equipped with a detection module, which includes a detection crossbar that contacts the bottom surface of the half shaft and an electronic dial indicator connected to the detection crossbar. The detection crossbar is reset by a spring.

[0014] In this process, after the half-shaft is transferred from the conveyor frame to the support assembly, the driving wheel and the driven wheel press the half-shaft together and drive it to rotate. The electronic dial indicator detects the curvature data in real time, and the straightening cylinder straightens the curved part by pressing it according to the detection data.

[0015] In one possible design, the conveyor frame includes: a fixed base, a sliding plate slidably connected to the fixed base, and two movable frames fixed to the top of the sliding plate; the top of the movable frames is provided with a mating groove; the fixed base is provided with a first screw driven by a first motor, and the sliding plate is threadedly connected to the first screw.

[0016] In one possible design, a slider is fixedly connected to one side of the movable seat, the top bracket is provided with a fixing box, and a second screw driven by a second motor is provided inside the fixing box, and the slider is threadedly connected to the second screw.

[0017] In one possible design, the detection module further includes a vertically arranged lifting rod, one end of which is slidably sleeved on the outer wall of the lifting rod, and the two ends of the spring are respectively connected to the bottom support of the lifting rod and the detection rod.

[0018] In one possible design, the first support seat of the first abutment part and the bottom of the two rollers are fixedly mounted on the same mounting plate, and the two rollers cooperate to form a V-shaped placement groove, and the second support seat of the second abutment part is guided to rise and fall by a support frame.

[0019] In one possible design, the fixing assembly further includes: two fixing frames fixed to the top of the processing base, one fixing frame having a mounting seat for mounting a drive motor slidably connected therein, and the other fixing frame having a sliding seat for mounting a driven wheel slidably connected therein, the mounting seat and the sliding seat being driven to rise and fall by corresponding third cylinders.

[0020] In one possible design, a PLC controller is fixedly mounted on one side of the processing base, the PLC controller being used to facilitate the operation of the equipment.

[0021] In one possible design, the surfaces of the driving wheel and the driven wheel are provided with anti-slip textures, and the rim height is adjustable to accommodate half-shafts of different diameters.

[0022] In this application, after the equipment is started, the operator can set the calibration parameters and start the running program through the PLC controller. The first motor on each of the two conveyor frames can drive the first screw to rotate, which in turn can drive the sliding plate to slide along the inner wall of the fixed seat, thus completing the movement of the two moving frames. The half-shaft to be processed is placed in the paired grooves of the conveyor frame, and through the movement of the corresponding two moving frames, the half-shaft can be gradually moved to the top of the support assembly of the processing seat.

[0023] Two first cylinders in the support assembly drive the corresponding mounting plates to rise, thereby allowing the first support base to lift both ends of the half-shaft. Two sets of paired rollers also assist in supporting the half-shaft. Next, the sliding seat and mounting seat in the fixing assembly, driven by the corresponding third cylinders, move downwards along the inner wall of the fixing frame, pressing the driving wheel and driven wheel against the surface of the half-shaft to fix it in place. Afterwards, the drive motor starts, rotating the half-shaft via the driving wheel. At this time, the detection crossbar of the detection module, pushed by the spring, can press tightly against the lower surface of the half-shaft. The radial runout generated by the rotation of the half-shaft is transmitted to the electronic dial indicator through the detection crossbar, allowing real-time detection of bending data and feedback to the PLC controller.

[0024] When excessive bending is detected, the drive motor rotates the half-shaft, causing the bent protrusion to face upwards. Then, the PLC controller controls the second motor to drive the second screw to rotate, moving the moving base and straightening cylinder horizontally to directly above the bending point. The second cylinder then synchronously lifts the adjacent second support base, forming a multi-point support structure. The piston rod of the straightening cylinder then extends, and the pressure block applies a vertical downward pressure to the bent part of the half-shaft to straighten it. The drive motor then drives the half-shaft to rotate again, allowing for multiple checks and straightening processes until the readings of multiple dial indicators all reach the set thresholds.

[0025] After straightening is completed, the fixing component can release the constraint on the half shaft, and the conveyor on the other side can move the corresponding moving frame to below the straightened half shaft. Then the support component descends, allowing the half shaft to fall into the corresponding groove. After that, the straightened half shaft can be moved out of the processing area by the movement of the conveyor, completing a single straightening operation.

[0026] Beneficial effects: In this utility model, the half-shaft straightening device is equipped with an advanced detection module, in which an electronic dial indicator can detect the bending data of the half-shaft in real time and feed the data back to the PLC controller; the PLC controller precisely controls the top pressure module of the straightening component according to the detection data, so that the top pressure block can accurately apply top pressure to the bent part of the half-shaft, thereby achieving precise straightening of the bending of the half-shaft, greatly improving the straightening accuracy, and ensuring that the straightened half-shaft meets high-quality standards;

[0027] In this utility model, the half-shaft straightening device achieves a continuous operation mode of automatic feeding and automatic unloading of half-shafts through a staggered double conveyor frame structure. Combined with the precise positioning of the moving frame driven by the first screw, it significantly improves material flow efficiency and reduces the risk of manual intervention.

[0028] In this utility model, the half-shaft straightening device forms a distributed stress-bearing structure by combining the double roller support of the first abutment part with the liftable multi-point support of the second abutment part. Combined with the lateral position adjustment function of the straightening cylinder, it can achieve precise pressing of the bending point and elastic compensation of the adjacent area, effectively suppressing rebound and protecting the surface integrity of the half-shaft.

[0029] In this invention, the half-shaft straightening device, through the electronic dial indicator in the detection module, can accurately measure the bending in real time and feed the data back to the PLC controller to precisely control the top-pressing module, achieving high-precision straightening of the half-shaft and ensuring the quality of the finished product. The staggered arrangement of the double conveyor frames, combined with the precise positioning of the moving frame driven by the first screw, enables automatic loading and unloading continuous operation, improving material flow efficiency and reducing the risk of manual interference. The combination of double rollers in the first abutment part and multi-point support in the second abutment part, combined with the lateral adjustment of the straightening cylinder, can accurately press the bending point, effectively suppressing springback and providing sufficient protection for the half-shaft.

The detection crossbar 30 is horizontally arranged and located between the two second abutment portions 21, below the half-shaft and cooperating with the outer wall of the half-shaft. When the half-shaft is bent, the detection bar 30 will move up and down under the action of the spring 31, thereby moving the detection end of the electronic dial indicator 32 to detect the degree of bending of the half-shaft.

[0047] Example 2: Reference Figure 1 , 2 3. Improvement based on Example 1: A half-shaft straightening device, which is applied to the field of automobile manufacturing technology;

[0048] In this embodiment, two conveyor frames 3 are respectively disposed on both sides of the processing base 1, and the two conveyor frames 3 are staggered to realize the transport and conveying of the half shaft to be processed. Specifically, the conveyor frame 3 consists of a fixed base 4, a sliding plate 5, and two movable frames 7. The sliding plate 5 is slidably disposed in the fixed base 4, and two support plates 6 are fixedly installed on its top. The bottom of each of the two movable frames 7 is fixedly connected to the top of the corresponding support plate 6. The top of each of the two movable frames 7 is provided with multiple grooves 8, and the two corresponding grooves 8 on the two movable frames 7 cooperate to complete the support and placement of the half shaft.

[0049] Furthermore, a first screw 9 is rotatably mounted inside the fixed base 4, and the sliding plate 5 is threadedly connected to the first screw 9. A first motor 10 is fixedly mounted on one side of the fixed base 4, and one end of the output shaft of the first motor 10 rotatably passes through one side of the fixed base 4 and is fixedly connected to one end of the first screw 9. When the first motor 10 is started, it drives the first screw 9 to rotate, thereby causing the sliding plate 5 to slide within the fixed base 4, which enables the horizontal movement of the movable frame 7 and completes the transport of the half-shaft.

[0050] In this embodiment, a PLC controller 2 is fixedly installed on one side of the processing base 1, and the equipment can be easily operated through the PLC controller 2.

[0051] However, as is well known to those skilled in the art, the working principles and wiring methods of the PLC controller 2, the first motor 10, the straightening cylinder 13, the second motor 19, the first cylinder 22, the second cylinder 27, the drive motor 37, and the third cylinder 39 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0052] The working principle and usage process of this technical solution are as follows: After the equipment is started, the operator can set the calibration parameters and start the running program through the PLC controller 2. The first motor 10 on the two conveyor frames 3 can drive the first screw 9 to rotate, which in turn can drive the sliding plate 5 to slide along the inner wall of the fixed seat 4, thus completing the movement of the two moving frames 7. The half shaft to be processed is placed in the paired grooves 8 of the conveyor frame 3. Through the movement of the corresponding two moving frames 7, the half shaft can be gradually moved to the support assembly above the processing seat 1.

[0053] The two first cylinders 22 in the support assembly can drive the corresponding mounting plates 23 to rise, thereby allowing the first support base 24 to lift both ends of the half shaft. The two sets of paired rollers 25 can also assist in supporting the half shaft. Next, the sliding seat 34 and the mounting seat 36 in the fixing assembly can move down along the inner wall of the fixing frame 33 under the drive of the corresponding third cylinder 39, so that the driving wheel 38 and the driven wheel 35 can press against the surface of the half shaft to complete the fixing of the half shaft. After that, the drive motor 37 starts and drives the half shaft to rotate through the driving wheel 38. At this time, the detection crossbar 30 of the detection module can be pressed against the lower surface of the half shaft by the thrust of the spring 31. The radial runout generated by the rotation of the half shaft will be transmitted to the electronic dial indicator 32 through the detection crossbar 30, which can detect the bending data in real time and feed it back to the PLC controller 2.

[0054] When excessive bending is detected, drive motor 37 rotates the half-shaft, causing the bent protrusion to face upwards. Then, PLC controller 2 controls second motor 19 to drive second screw 18 to rotate, moving moving seat 16 and straightening cylinder 13 horizontally to directly above the bending point. Next, second cylinder 27 synchronously lifts the adjacent second support seat 28, forming a multi-point support structure. Then, the piston rod of straightening cylinder 13 extends, and pressure block 14 applies a vertically downward pressure to the bent part of the half-shaft to straighten it. Drive motor 37 then drives the half-shaft to rotate again, allowing for multiple checks and straightenings until the values ​​measured by multiple electronic dial gauges 32 all reach the set threshold.

[0055] After straightening is completed, the fixing component can release the constraint on the half shaft, and the other side conveyor 3 can move the corresponding moving frame 7 to below the straightened half shaft. Then the support component descends, allowing the half shaft to fall into the corresponding groove 8. After that, the straightened half shaft can be moved out of the processing area by the movement of the conveyor 7, completing a single straightening operation.

[0056] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
