Description

Technical Field

[0001] The utility model belongs to the technical field of automobile part processing, and particularly relates to an automobile chassis part processing device. Background Art

[0002] The automobile chassis is an important part of the automobile. It bears the weight of the whole body and the vehicle, and provides necessary support, stability and protection. There are many automobile chassis parts, which can be mainly divided into four major parts: the drive system, the running system, the steering system and the braking system. During the manufacturing process of the automobile, welding is often used to connect some parts, including connecting different chassis parts.

[0003] As the core component of the steering system, the installation and fixation of the steering gear are particularly important. The steering gear mounting sleeve and the steering gear mounting plate are exactly the components used to install and fix the steering gear. They ensure that the steering gear can work stably and effectively transmit the steering operation of the driver to the wheels, so as to control the driving direction of the vehicle. The steering gear mounting sleeve and the steering gear mounting plate are generally connected by a welding device during installation. In some cases, considering factors such as connection strength, all parts of the contact surface between the two need to be welded. At this time, if a device such as a motor is used to drive the two to rotate, considering that the welding process requires a stable welding environment and sufficient welding time to ensure the quality and strength of the weld, the relatively fast rotation speed of the two will affect the welding effect. If the welding device is set to rotate around the two, a larger processing space needs to be provided. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an automobile chassis part processing device for solving the problems in the above background art.

[0005] To solve the above technical problems, the utility model provides an automobile chassis part processing device, including:

[0009] And a fixing member, for cooperating with the fixing part to fix all the parts to be processed; at least part of the fixing member remains relatively stationary with respect to the non-output end of the rotating part.

[0010] With such a design, it is possible to avoid the need to provide a large space for the welding part to move, and it is also possible to avoid the situation where the welding effect is affected by the relatively fast rotation speed of the part to be welded.

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0040] Embodiment 1

[0041] As Figures 1 to 4 shown, the present utility model provides a processing device for automobile chassis components, including:

[0042] A welding part 1, having a welding head 11, the welding head 11 can move in multiple directions to adapt to the shapes of various regions of the part to be welded, and the welding part 1 is used for welding the part to be welded;

[0043] A fixing part 2, having a fixing groove 21, for fixing the part to be processed;

[0044] A rotating part 3, installed at the bottom of the fixing part 2, for driving the fixing part 2 to rotate around its own axis so that all regions of the part to be welded 1 can cooperate with the welding head 11 for welding;

[0045] And a fixing member 4, for cooperating with the fixing part 2 to fix all the parts to be processed; at least part of the fixing member 4 remains relatively stationary with respect to the non-output end of the rotating part 3.

[0046] The welding head 11 can move in multiple directions to adapt to the shapes of various regions of the part to be welded 1, and the welding part 1 is used for welding the part to be welded 1. The following gives some specific ways for reference: The welding part 1 can be set as a multi-axis robot (such as a six-axis robot). Due to its high flexibility and precision, it is very suitable for welding tasks with complex shapes. The welding head 11 is installed on the end effector of the robot. Through the multi-axis movement of the robot, the welding head 11 can move freely in three-dimensional space to achieve precise welding of each surface of the part to be welded 1; when the cross-section of the part to be welded 1 is circular, the welding part 1 can be set as a circumferential seam automatic welding machine. After the part is fixed, the welding head 11 rotates around the part to achieve automatic welding. According to the specific shape and welding requirements of the part, a horizontal, vertical or inclined circumferential seam automatic welding machine can be selected.

[0047] During the welding process, the fixing part 2 and the fixing member 4 cooperate to fix all the parts to be processed. Taking two parts as an example, they are divided into the first part 8 and the second part 9. In some cases, a part of the first part 8 is located in the fixing groove 21, the second part 9 is attached above the first part 8, and the fixing member 4 can apply a force to the second part 9 from above. Thus, the fixing of all the parts to be processed is completed. The first part 8 and the second part 9 can respectively refer to the steering gear mounting sleeve and the steering gear mounting plate. The first part 8 and the second part 9 can be spot-welded in advance to avoid inaccurate positioning of the two during subsequent operations and to avoid differences between the position of the contact surface between the two and the predetermined position.

[0048] During welding, taking the cross-section of the welding part 1 being circular as an example, other parts of the welding part 1 drive the welding head 11 to move to weld a partial area of the welding part 1. Then, the rotating part 3 indirectly drives the welding part 1 to rotate, so that the remaining parts of the welding part 1 face the welding head 11, and then the welding process is repeated. With this setting, it is possible to avoid providing a large space for the movement of the welding part 1 and to avoid the situation where the welding effect is affected due to the relatively fast rotation speed of the welding part 1.

[0049] Optionally, the rotating part 3 is set as a motor or other device that can drive the fixing part 2 to rotate.

[0050] For the fixing member 4, the shape of the fixing groove 21 on it can be adaptively adjusted according to the shape of the part.

[0051] Optionally, the present utility model may further include a controller and some sensors to automatically control the operation of devices such as the rotating part 3 and the welding part 1, and can also control the rotation angle of the fixing part 2 during each rotation process and the moving speed of the welding head 11 during each welding process, etc. There is no specific limitation here. The present utility model is used to protect the mechanical structure and does not protect the controller, sensors and other structures related to electrical connection control.

[0052] Embodiment 2

[0053] In this embodiment, the fixing member 4 includes a driving sub-member 41, a pressing sub-member 42, and a connecting sub-member 43. One end of the connecting sub-member 43 is connected to the driving sub-member 41, and the pressing sub-member 42 is connected to the driving sub-member 41; the connecting sub-member 43 remains relatively stationary with the non-output end of the rotating part 3; the driving sub-member 41 can drive the pressing sub-member 42 to apply a force to the part from above to cooperate with the fixing part 2 to fix all the parts to be processed.

[0054] The fixing member 4 includes a driving sub-member 41, a pressing sub-member 42, and a connecting sub-member 43. When fixing, the driving sub-member 41 can drive the pressing sub-member 42 to apply a force on the component from above to cooperate with the fixing portion 2 to fix all the components to be processed. Such a setting facilitates the fixing of components with different shapes and has a wider application range. The driving sub-member 41 can adopt existing devices such as a cylinder.

[0055] When the fixing portion 2 rotates, the connecting sub-member 43 does not rotate synchronously with the rotating portion 3, avoiding the connecting sub-member 43 being between the welding head 11 and the portion 1 to be welded during some time periods and hindering the welding head 11 from welding the portion 1 to be welded. For the rotating portion 3, when it is a motor, its output end is the motor shaft, and the non-output end includes the motor housing.

[0056] Embodiment 3

[0057] In this embodiment, the pressing sub-member 42 includes a pressing portion 421 and a rotating portion 422. The pressing portion 421 is connected to the driving sub-member 41, and the rotating portion 422 is rotatably connected to the bottom of the pressing portion 421 and is used to contact the component.

[0058] The pressing sub-member 42 includes a pressing portion 421 and a rotating portion 422. The one directly contacting the component is the rotating portion 422. Such a setting enables the driving sub-member 41 to stop operating when the rotating portion 3 starts, so that the pressing portion 421 stops applying a large pressure to the rotating portion 422, allowing the rotating portion 422 to rotate together with the component to be processed, avoiding the influence of the pressure applied by the pressing portion 421 on the driving of the component to be processed by the rotating portion 3. The pressing portion 421 can be set as a plate-like structure, and the rotating portion 422 can be set as a cylindrical structure.

[0059] The pressing portion 421 and the rotating portion 422 can be rotatably connected through a bearing.

[0060] Embodiment 4

[0061] In this embodiment, a lifting portion 5 is provided at the bottom of the rotating portion 3. The lifting portion 5 is used to adjust the position of the rotating portion 3 in the vertical direction, and the other end of the connecting sub-member 43 is connected to the lifting portion 5.

[0062] The lifting portion 5 is used to adjust the position of the rotating portion 3 in the vertical direction, and further adjust the position of the component to be processed, so as to adapt to different components. The lifting portion 5 can be set as an existing device such as a scissor lift table.

[0063] Embodiment 5

[0064] In this embodiment, a plurality of connecting members 6 are detachably connected to the outside of the fixing portion 2 and are uniformly distributed in a circumferential manner around the axis of the fixing portion 2;

[0065] A limiting part 7 corresponding to the connecting part 6 is connected to the lifting part 5.

[0066] The arrangement of the connecting part 6 and the limiting part 7 can prevent the rotation angle of the part 1 to be welded from being too large during each rotation due to the relatively high rotation speed of the rotating part 3. During use, the connecting part 6 rotates with the fixed part 2 and stops rotating when the connecting part 6 touches the limiting part 7.

[0067] Embodiment 6

[0068] In this embodiment, the limiting part 7 includes a driving part 71 and a limiting part 72. The driving part 71 is installed on the lifting part 5, and the limiting part 72 is installed on the driving part 71. The driving part 71 can drive the limiting part 72 to move horizontally to limit the moving range of the connecting part 6, thereby limiting the rotation angle of the fixed part 2.

[0069] Optionally, the driving part 71 is set as an existing device such as a servo motor, which can drive the limiting part 72 to move horizontally.

[0070] Initially, one of the connecting parts 6 is in contact with the limiting part 72. Then, the driving part 71 drives the limiting part 72 away from the limiting area. Then, the rotating part 3 drives each connecting part 6 to rotate. Subsequently, the driving part 71 drives the limiting part 72 to reset. When the other connecting parts 6 touch the limiting part 72, the rotating part 3 stops operating. With such an arrangement, the rotation angle of the fixed part 2 can be limited. It should be added that structures such as a laser sensor and a control structure can be added to achieve the following effects: after the connecting part 6 enters the predetermined area, the rotating part 3 stops operating within a predetermined time, which will not be specifically described here.

[0071] In the description of this specification, the descriptions referring to terms such as "one embodiment", "example", "specific example", etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0072] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
