Technical Field
[0001] The utility model belongs to the technical field of automobile welding fixtures and relates to a high-flexibility servo switching clamping unit. Background Art
[0002] The competition among major automobile manufacturers in the world is becoming increasingly fierce. The speed of automobile product updates and iterations has far exceeded that of the past. Whoever can quickly seize the market will win the first opportunity. However, the development project of body-in-white welding fixtures requires several necessary stages, including design, manufacturing, installation, and debugging. It takes at least 3-4 months to develop a welding fixture for a new model, and the developed fixture can only match the same series of products with little change in shape. It is difficult to produce products with large changes in shape on the same line. Often, a tool can only be compatible with 3-5 models at most. The development difficulty increases linearly with the increase in the number of models, and the development cycle is also forced to be extended. Summary of the invention

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0015] like Figure 1 As shown,
[0016] A high-flexibility servo switching clamping unit, characterized in that it includes a Base frame 2, on which an X-axis servo module 3 is provided, and the X-axis servo module 3 includes a linear guide 4, and the linear guide 4 is fixedly connected to the Base frame 2, and a ball screw 5 is provided on the linear guide 4, and a sliding carrier 6 is provided on the ball screw 5, and a servo motor 7 and a return belt box 8 are fixedly connected to the Base frame 2, and a belt is provided in the return belt box 8, and the servo motor 7 and the ball screw 5 are connected to each other by a belt return, and a Y-axis servo module 9 is provided on the sliding carrier 6, and a Z-axis servo module 10 is provided on the Y-axis servo module 9, and the X-axis servo module 3, the Y-axis servo module 9 and the Z-axis servo module 10 are of the same structure, and a pneumatic clamping unit is provided on the Z-axis servo module 10.
[0017] In this embodiment, the three-axis servo module is adjusted in the three directions of X, Y, and Z to drive the cylinder clamping unit to achieve the matching of the clamping positioning point. Under the premise of satisfying the adjustment range of the three axes, the motor and the lead screw adopt a synchronous toothed belt return connection structure, and the servo motor 7 is hidden inside the module to reduce the structural volume as much as possible. The linear guide 4 and the ball screw are both of high-precision specifications, which can ensure that the accuracy of the clamping point is within ±0.1mm. This product can quickly cut the position of the clamping positioning point. When a new body-in-white product is integrated into the fixture, the fixture can be switched by adjusting the servo parameters, which greatly shortens the development cycle of the welding fixture. At the same time, the design of the welding fixture for co-production of multiple models also becomes simple. When a model is discontinued, the traditional welding fixture is discarded, and the flexible fixture composed of a high-flexibility servo switching clamping unit can continue to be used in new models, reducing material waste and having great significance for environmental protection. This patent can shorten the development cycle of multi-model co-linear welding fixtures from the traditional 3-4 months to 3-5 days. In addition, it can greatly reduce the design difficulty of multi-model co-linear fixtures. The fixtures of large-scale white-body parts assemblies such as side panel assemblies and floor assemblies are standardized. The development of welding fixtures does not need to wait until the body product styling development is completed before implementation. Standardized flexible fixtures can be developed ahead of vehicle models, and the servo parameters can be adjusted after the vehicle model development is completed. During the product trial production process, the iterative styling changes of small versions are often not too large. The flexible servo switching clamping unit can be changed and put into production at any time, and the advantages are more obvious.
[0018] In this embodiment, the pneumatic clamping unit includes a clamping cylinder 11 , which is disposed on the Z-axis servo module 10 , and a positioning block 12 is disposed on the clamping cylinder 11 .
[0019] In this embodiment, the X-axis servo module 3 , the Y-axis servo module 9 and the Z-axis servo module 10 are all provided with anti-dust covers 13 .
[0020] In this embodiment, an oiling nozzle 14 is provided on the Base frame 2 .
[0021] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0022] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
