Description

Technical Field

[0001] This utility model relates to the field of automotive axle technology, specifically to an automotive axle fixing welding fixture. Background Technology

[0002] The axle is a key load-bearing component in the vehicle chassis system, and its manufacturing quality directly affects the safety and reliability of the entire vehicle. Welding is a core process in axle assembly manufacturing, and the performance of welding fixtures plays a decisive role in welding accuracy and efficiency.

[0003] A currently used automotive axle fixing welding fixture, as disclosed in Chinese patent document CN219094087U, features a top plate at the top of a support column, a first motor with an upward-facing output fixedly connected to the lower end of the base plate, a transmission belt rolling between a first pulley and a second pulley, an axle clamp fixedly connected to the top of a rotating shaft, an axle gearbox fixedly fixed inside the axle clamp, a second motor fixedly connected to the output end of a first hydraulic actuator, and a vertical rod fixedly connected to the lower end of a crossbar away from the rotating block, with a welding head connected to the lower end of the vertical rod. The advantages of this invention compared to existing technologies are: This automotive axle fixing welding fixture allows the second motor to rotate counterclockwise, meaning the welding head rotates in the opposite direction to the axle gearbox being welded, increasing the relative speed. This, in turn, initiates welding of the axle gearbox, significantly increasing welding speed and improving welding efficiency.

[0004] While the above patents have solved the problems mentioned in the background technology, they still have the following shortcomings: 1. The equipment relies on a rotating rod to rotate the threaded rod, which requires manual operation and exhibits low clamping efficiency, thus affecting the clamping progress of the automobile axle and delaying subsequent welding operations; 2. The equipment relies solely on a hydraulic device to achieve the support function, and the movement and adjustment of this hydraulic device require user judgment, which can easily lead to inaccurate extension and contraction of the hydraulic device, thereby affecting the stability of the device and hindering its subsequent use.

[0005] In summary, this utility model solves the problems in the background art by designing an automotive axle fixing welding fixture. Utility Model Content

[0006] The purpose of this utility model is to provide an automotive axle fixing welding fixture to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A welding fixture for fixing an automotive axle includes a welding table and a support base disposed below the welding table. A welding frame is fixedly installed on the outer side of the welding table. A controller is disposed on the left side of the welding frame, and a first electric push rod is fixedly installed on the right side of the welding frame. A sliding groove is formed on the top surface of the welding frame, and a sliding block is disposed inside the sliding groove. A welding machine is disposed at the bottom of the sliding block, and a second electric push rod is disposed at the top of the sliding block. An electric rotating seat is fixedly installed on the top of the welding table, and a bearing plate is disposed on the top of the electric rotating seat. A clamping and positioning mechanism is disposed on the top of the bearing plate. Inclination detectors are fixedly installed on the outer side of the support base, and hydraulic cylinders are fixedly installed on the top of the support base. A friction block is disposed at the bottom of the support base.

[0009] The clamping and positioning mechanism includes a clamping groove and a clamping motor. The clamping groove is formed on the top surface of the bearing plate. A transmission screw and a clamping block are respectively arranged inside the clamping groove. A rubber clamping pad is arranged on the inner side of each clamping block.

[0010] Furthermore, the output end of the clamping motor extends through the rear surface of the bearing plate and is coaxially connected to the rear end of the transmission screw;

[0011] Through the above technical solution, the clamping motor can drive the transmission screw to rotate.

[0012] Furthermore, the clamping grooves are equidistant from the top central axis of the bearing disk, and the outer surface of the clamping block slides in contact with the inner wall of the clamping groove.

[0013] Through the above technical solution, the clamping groove can slide smoothly with the surface of the clamping block.

[0014] Furthermore, the type of the transmission screw is a bidirectional screw, and the clamping block is threaded onto the outer surface of the transmission screw, and the clamping block is symmetrically distributed front and back about the outer surface of the transmission screw;

[0015] Through the above technical solution, the transmission screw can drive the clamping blocks to move in opposite directions or away from each other, which makes it easier for the clamping blocks to drive the rubber clamping pads to clamp the automobile axle.

[0016] Furthermore, the bottom of the welding table is fixedly contacted with the top of the support base via a connecting column, and the rotating end of the electric rotating base is fixed to the bottom surface of the bearing plate;

[0017] Through the above technical solution, the support base can be fixed to the welding table through the connecting column, and the electric rotating base can drive the bearing base to rotate.

[0018] Furthermore, the telescopic end of the first electric actuator passes through the right side surface of the welding frame and is fixedly in contact with the right side of the sliding block, and the telescopic end of the second electric actuator passes through the top surface of the sliding block and is fixedly in contact with the top of the welding machine.

[0019] Through the above technical solution, the No. 1 electric actuator can adjust the lateral displacement of the sliding block, and the No. 2 electric actuator can drive the welding machine to move downward.

[0020] Furthermore, the hydraulic cylinders are distributed in a mirror image with respect to the top surface of the support base, and the telescopic end of the hydraulic cylinder passes through the top surface of the support base and is fixed to the top surface of the friction block. The number of tilt detectors is consistent with the number of hydraulic cylinders, and the position of the tilt detectors is corresponding to that of the hydraulic cylinders.

[0021] Through the above technical solution, the tilt detector can measure the levelness of the support base, and the hydraulic cylinder can drive the friction block to move downward, so that the friction block forms a tight contact with the ground, which facilitates stable support of the support base.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. In this utility model, an automotive axle fixing welding fixture is provided. By utilizing the structural design of the clamping and positioning mechanism, the transmission screw is driven by the clamping motor, causing the transmission screw to bring the clamping block close to and in contact with the surface of the automotive axle. This achieves the purpose of automatically clamping and positioning the automotive axle, improving the clamping progress of the equipment and facilitating subsequent welding operations.

[0024] 2. In this utility model, by setting up an automotive axle fixing welding fixture, the tilt angle detector, hydraulic cylinder, controller and friction block are structurally designed. The tilt angle detector can measure the horizontal state of the support base and feed it back to the controller. The controller then starts the hydraulic cylinder, causing the hydraulic cylinder to drive the friction block to support and adjust against the ground, thereby achieving the purpose of stable support for the equipment, which is beneficial to subsequent use.

[0034] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0035] A welding fixture for fixing automobile axles includes a welding table 1 and a support base 2 disposed below the welding table 1. A welding frame 3 is fixedly installed on the outer side of the welding table 1. A controller 301 is disposed on the left side of the welding frame 3. A first electric push rod 302 is fixedly installed on the right side of the welding frame 3. A sliding groove 303 is formed on the top surface of the welding frame 3. A sliding block 304 is disposed inside the sliding groove 303. A welding machine 305 is disposed at the bottom of the sliding block 304. A second electric push rod 306 is disposed at the top of the sliding block 304. An electric rotating seat 4 is fixedly installed on the top of the welding table 1. A bearing plate 401 is disposed on the top of the electric rotating seat 4. A clamping and positioning mechanism 5 is disposed on the top of the bearing plate 401. An inclination detector 201 is fixedly installed on the outer side of the support base 2. A hydraulic cylinder 202 is fixedly installed on the top of the support base 2. A friction block 203 is disposed at the bottom of the support base 2.

[0036] It should be noted that the first electric actuator 302, the second electric actuator 306, the hydraulic cylinder 202, the tilt detector 201, and the electric rotary seat 4 are electrically connected to the controller 301 via wires.

[0037] Specifically, the bottom of the welding table 1 is fixedly contacted with the top of the support base 2 through the connecting column, and the rotating end of the electric rotating base 4 is fixed to the bottom surface of the bearing plate 401.

[0038] In this implementation plan, such as Figure 1 As shown, the electric rotary seat 4 can drive the bearing plate 401, thereby achieving the function of rotating the position of the automobile axle.

[0039] Specifically, the telescopic end of the first electric actuator 302 passes through the right side surface of the welding frame 3 and is in fixed contact with the right side of the sliding block 304, and the telescopic end of the second electric actuator 306 passes through the top surface of the sliding block 304 and is in fixed contact with the top of the welding machine 305.

[0040] In this implementation plan, such as Figure 3 As shown, the first electric actuator 302 can drive the sliding block 304 laterally, and the second electric actuator 306 can drive the welding machine 305 downward, thereby achieving the function of adjusting the position of the welding machine 305 and facilitating the contact between the welding head of the welding machine 305 and the automobile axle.

[0041] Specifically, the hydraulic cylinders 202 are distributed in a mirror image with respect to the top surface of the support base 2, and the telescopic end of the hydraulic cylinders 202 passes through the top surface of the support base 2 and is fixed to the top surface of the friction block 203. The number of tilt detectors 201 is the same as that of the hydraulic cylinders 202, and the position of the tilt detectors 201 is corresponding to that of the hydraulic cylinders 202.

[0042] In this implementation plan, such as Figure 1and Figure 2 As shown, the tilt detector 201 can measure the levelness of the support 2 and feed the measured value back to the controller 301. The controller 301 can then control the extension and retraction of the hydraulic cylinder 202. The hydraulic cylinder 202 can vertically displace the friction block 203, thereby achieving stable contact between the friction block 203 and the ground, thus meeting the stable support requirements of the equipment.

[0043] In this embodiment, please refer to Figure 1 and Figure 4 The clamping and positioning mechanism 5 includes a clamping groove 501 and a clamping motor 502. The clamping groove 501 is opened on the top surface of the bearing plate 401. The inside of the clamping groove 501 is respectively provided with a transmission screw 503 and a clamping block 504. The inner side of the clamping block 504 is provided with a rubber clamping pad 505.

[0044] Specifically, the output end of the clamping motor 502 passes through the rear surface of the bearing plate 401 and is coaxially connected to the rear end of the transmission screw 503. The clamping groove 501 is equidistant from the top center axis of the bearing plate 401. The outer surface of the clamping block 504 is in sliding contact with the inner wall of the clamping groove 501. The transmission screw 503 is a bidirectional screw. The clamping block 504 is threaded onto the outer surface of the transmission screw 503. The clamping block 504 is symmetrically distributed front and back from the outer surface of the transmission screw 503. The clamping motor 502 is electrically connected to the controller 301 through a wire.

[0045] In this implementation plan, such as Figure 4 As shown, the clamping motor 502 can drive the transmission screw 503 to rotate. Under the threaded transmission between the transmission screw 503 and the clamping block 504, the clamping block 504 causes the rubber clamping pad 505 to contact the automobile axle, thereby achieving the function of quickly clamping and fixing the automobile axle and meeting the needs of the user.

[0046] The working process of this utility model is as follows: When using a welding fixture for fixing an automobile axle, after the equipment is powered on, the tilt detector 201 can detect the levelness data of the support 2 in real time and transmit it to the controller 301. Subsequently, the controller 301 controls the corresponding hydraulic cylinder 202 to extend and retract, pushing the friction block 203 to contact the ground until the entire welding table 1 is adjusted to an absolutely level state. Then, the clamping motor 502 is started, and the output end of the clamping motor 502 drives the transmission screw 503 to rotate. The clamping blocks 504, which are symmetrically arranged on the front and rear of the transmission screw 503, move synchronously towards each other. The clamping blocks 504 drive the rubber clamping pad 505 to contact the surface of the automobile axle, thereby achieving the function of stable clamping of the automobile axle, which facilitates subsequent welding operations and meets the needs of users.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
