[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] It should be noted that if there are directional indications (such as up, down, bottom, top, etc.) involved in this embodiment, the directional indication is only used to explain the relative position relationship, movement, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. Unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0024] like Figure 1-Figure 6 As shown, a semiconductor equipment precision pipe welding device includes a horizontal workbench 1, characterized in that: the horizontal workbench 1 is provided with two tooling bases 2 arranged opposite to each other, the tooling base 2 is detachably connected with a cushion block 3, and the cushion block 3 is provided with a U-shaped slot 301 for placing a pipe 4;

[0025] The gasket 3 is detachably connected with a cover plate 5 capable of blocking the opening of the U-shaped slot 301, and the cover plate 5 is tangent to the outer periphery of the pipe fitting 4, so that the pipe fitting 4 can rotate in the U-shaped slot 301;

[0026] A top block 6 capable of abutting against the axial end of the pipe fitting 4 is arranged on one of the tooling bases 2 , and a quick clamp 7 capable of abutting against the axial end of the pipe fitting 4 is arranged on the other tooling base 2 .

[0027] Specifically, in the welding of the pipe fitting 4, there are situations where the straightness and concentricity of the product are required to be high. The horizontal workbench 1 is a relatively horizontal work platform, and the tooling base 2 arranged thereon is also relatively horizontal. The two ends of the pipe fitting 4 to be welded can be embedded in the U-shaped slot 301 on the cushion block 3, and at the same time, the opening of the U-shaped slot 301 is blocked by the cover plate 5, which can prevent the pipe fitting 4 from escaping from the U-shaped slot 301, thereby ensuring the straightness and concentricity of the pipe fitting 4 during welding. In the present technical solution, the cover plate 5 can be fixed to the cushion block 3 by bolts. Next, before welding the pipe fitting 4, the pipe fitting 4 can be preliminarily welded by spot welding. When welding the gap connecting the pipe fitting 4, it can be manually adjusted so that the axial end of the pipe fitting 4 can rotate along the fixed rotation axis in the area enclosed between the U-shaped slot 301 and the cover plate 5, so as to facilitate the overall welding of the pipe fitting 4. Furthermore, in order to fix the pipe fitting 4 at a certain fixed angle, one end of the quick clamp 7 can be directly pressed against one side axial end of the pipe fitting 4, so that the other end of the pipe fitting 4 is pressed against the top block 6, thereby fixing the position of the pipe fitting 4 and preventing the pipe fitting 4 from moving and affecting the quality of welding.

[0028] In the present technical solution, the pipe fitting 4 is welded from a tubular body and two connecting pieces with keyways disposed at both ends of the tubular body.

[0029] Furthermore, to ensure that the keyways at both ends of the pipe 4 are at the same horizontal position, as Figure 1 As shown, the spacer block 3 is movably provided with a stopper block 8 that can be inserted into the U-shaped groove, and one end of the stopper block 8 can be plugged into the keyway on the pipe fitting 4. When the pipe fitting 4 is initially spot-welded, the connecting pieces on the pipe fitting 4 can be placed in the U-shaped slots 301 on the two spacers 3, respectively, and the connecting pieces are rotated, and a certain thrust is applied to the stopper block 8 until one end of the stopper block 8 is inserted into the keyway, so that the two end components of the pipe fitting 4 are in the same horizontal position.

[0030] Further, such as Figure 4 As shown, the limit block 8 is provided with a concave groove 9 arranged along its displacement direction, and the cushion block 3 is pierced with a limit column 10 which can abut against the bottom of the concave groove 9. When the limit block 8 is displaced relative to the cushion block 3, the limit column 10 can abut against the side wall of the limit block 8, thereby limiting the displacement distance of the limit column 10 and preventing the limit block 8 from detaching from the cushion block 3 or being lost.

[0031] In this embodiment, if Figure 5 As shown, the pad 3 is movably embedded with a pin 11 that can be plugged into the tooling base 2. The pad 3 can be quickly installed on the tooling base 2 through the pin 11, and can also be quickly removed from the tooling base 2, which can meet the diverse working requirements of the precision pipe welding device of semiconductor equipment.

[0032] Furthermore, a fixing bolt 12 which can be threadedly connected to the tooling base 2 is provided on the top block 6. It is convenient to disassemble and replace top blocks 6 of different sizes, meeting the diversified working requirements of the precision pipe welding device of semiconductor equipment.

[0033] Further, such as Figure 1 As shown, a plurality of evenly arranged mounting holes 101 are provided on the horizontal workbench 1, and the tooling base 2 can be connected to the mounting holes 101 on the horizontal workbench 1 through standard parts such as positioning pins and bolts. The position of the tooling base 2 can be adjusted according to the specifications of the pipe fittings 4, which can meet diverse work needs and has strong adaptability.

[0034] Working principle: According to the specifications of the pipe fitting 4 to be welded, the installation position of the tooling base 2 is adaptively adjusted, and suitable pads 3, top blocks 6, etc. are selected and replaced to meet diverse work needs. Then, one of the connectors can be preliminarily welded to the tubular body by spot welding, and then the two connectors are respectively placed in the U-shaped slots 301 on the two pads 3, the connector is rotated, and a certain thrust is applied to the limit block 8 until one end of the limit block 8 is inserted into the keyway, so that the two end components of the pipe fitting 4 are in the same horizontal position, and then the other connector is preliminarily welded to the tubular body by spot welding. Then, the cover plate 5 is installed on the pad 3, and the pipe fitting 4 is fixed as a whole by the quick clamp 7, and the pipe fitting 4 can be welded. It meets the situation where the straightness and concentricity requirements of the product are high. When it is necessary to weld the other side of the pipe fitting 4, the lock of the quick clamp 7 on the pipe fitting 4 can be released, and the pipe fitting 4 can be rotated.

[0035] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
