Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and in particular to a welding auxiliary fixture. Background Technology

[0002] In the welding process, the positioning accuracy and stability of the workpiece directly affect the welding quality. Traditional welding fixtures often suffer from problems such as inaccurate positioning, cumbersome clamping, and inconvenient workpiece removal, resulting in low welding efficiency and insufficient yield. Therefore, there is an urgent need to design a welding auxiliary fixture that is compact, easy to operate, and can reliably fix the workpiece to solve the above-mentioned technical problems.

[0003] Therefore, in view of the shortcomings of existing technologies, it is necessary to design something to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the present invention aims to provide a welding auxiliary fixture.

[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a welding auxiliary fixture, comprising:

[0006] A fixture base, wherein the fixture base is provided with a positioning groove, the positioning groove being matched with the shape of the workpiece to be welded;

[0007] An ejection mechanism configured to eject a workpiece from the positioning slot;

[0008] A clamping mechanism configured to clamp the workpiece into the positioning groove.

[0009] The preferred technical solution is as follows: the ejection mechanism consists of a lifting cylinder and a lifting block. The lifting cylinder is located below the fixture seat, and the lifting block is located in the positioning groove. The lifting cylinder is used to drive the lifting block to move up and down in the positioning groove.

[0010] A preferred technical solution is as follows: the clamping mechanism consists of a telescopic cylinder, a hinge ear, a hinge arm, a clamping arm, and a clamping frame. The telescopic cylinder is located on the outside of the fixture seat. The hinge ear is located between the fixture seat and the telescopic cylinder. One end of the hinge arm is hinged to the hinge ear, and the other end of the hinge arm is hinged to the middle section of the clamping arm. One end of the clamping arm is hinged to the telescopic end of the telescopic cylinder. The clamping frame is fixed to the other end of the clamping arm and is correspondingly arranged with respect to the positioning groove.

[0011] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0012] Precise positioning: The positioning groove matches the shape of the workpiece, reducing clamping errors and improving welding consistency.

[0013] Reliable clamping: The articulated clamping mechanism amplifies the clamping force through mechanical transmission, ensuring the workpiece is stable and reducing the risk of welding misalignment.

[0014] Easy to operate: Cylinder drive enables automated clamping and ejection, reducing manual intervention and improving production efficiency.

[0015] Wide applicability: The modular design allows it to be adapted to workpieces of different shapes by replacing components such as positioning slots and clamping frames, thus expanding its application scenarios. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the overall structure of the fixture involved in this utility model. Detailed Implementation

[0017] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0018] Please see Figure 1 It should be noted that in the description of this utility model, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. These terms are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. The terms "horizontal," "vertical," and "suspended," etc., do not indicate that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0019] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Example:

[0021] like Figure 1 As shown, according to a general technical concept of this utility model, a welding auxiliary fixture is provided, comprising:

[0022] The fixture base 1 is provided with a positioning groove 11, which matches the shape of the workpiece to be welded.

[0023] Ejection mechanism 2 is configured to eject the workpiece from positioning groove 11;

[0024] The clamping mechanism 3 is configured to clamp the workpiece in the positioning groove 11.

[0025] like Figure 1 As shown, in an exemplary embodiment of this utility model, the ejection mechanism 2 is composed of a lifting cylinder 21 and a lifting block 22. The lifting cylinder 21 is located below the fixture seat 1, and the lifting block 22 is located in the positioning groove 11. The lifting cylinder 21 is used to drive the lifting block 22 to move up and down in the positioning groove 11.

[0026] It should be noted that after the workpiece is positioned in the positioning groove 11 for welding, the workpiece is prone to sticking to the bottom of the positioning groove 11. When using a traditional positioning structure, it is difficult for the operator to remove the workpiece from the positioning groove 11. However, by using the ejection mechanism 2, the lifting block 22 can be ejected from the positioning groove 11 by the lifting cylinder 21, thereby ejecting the workpiece from the positioning groove 11 so that the operator can remove the workpiece.

[0027] like Figure 1 As shown, in an exemplary embodiment of this utility model, the clamping mechanism 3 is composed of a telescopic cylinder 31, a hinge ear 32, a hinge arm 33, a clamping arm 34, and a clamping frame 35. The telescopic cylinder 31 is located on the outside of the fixture seat 1, the hinge ear 32 is located between the fixture seat 1 and the telescopic cylinder 31, one end of the hinge arm 33 is hinged to the hinge ear 32, the other end of the hinge arm 33 is hinged to the middle section of the clamping arm 34, one end of the clamping arm 34 is hinged to the telescopic end of the telescopic cylinder 31, and the clamping frame 35 is fixed to the other end of the clamping arm 34 and is correspondingly arranged with the positioning groove 11.

[0028] Therefore, this utility model has the following advantages:

[0029] Precise positioning: The positioning groove matches the shape of the workpiece, reducing clamping errors and improving welding consistency.

[0030] Reliable clamping: The articulated clamping mechanism amplifies the clamping force through mechanical transmission, ensuring the workpiece is stable and reducing the risk of welding misalignment.

[0031] Easy to operate: Cylinder drive enables automated clamping and ejection, reducing manual intervention and improving production efficiency.

[0032] Wide applicability: The modular design allows it to be adapted to workpieces of different shapes by replacing components such as positioning slots and clamping frames, thus expanding its application scenarios.
