Abstract
Description
Technical Field
[0001] The utility model relates to a tooling fixture, specifically a double - assembled pipe fitting tooling fixture. Background Art
[0002] The structure of the double - assembled pipe fitting generally includes two joints and an iron pipe. The left and right ends of the iron pipe are welded to the two joints. Currently, for welding the double - assembled pipe fitting, automatic welding equipment or manual welding tooling can be used. Compared with automatic welding equipment, the cost of manual welding tooling is lower. Due to cost considerations, some factories still use manual welding tooling. The structure of the current manual welding tooling generally includes a base and a tooling main body fixed on the base. The tooling main body includes two slots for placing the joints and a rest table for placing the iron pipe. During use, first, the two joints are clamped into the slots, and then the iron pipe is placed on the top of the rest table. The tooling main body is pre - produced according to the length of the double - assembled pipe fitting to be welded. The iron pipe is clamped between the two joints, and then an operator holds a welding device to weld the two ends of the iron pipe. The welding is carried out in parts first. After a part of the iron pipe and the two joints are welded together, the whole is taken down to weld the remaining parts.
[0003] The above - mentioned existing - technology manual welding tooling often has the following problems when in use: The joints are only placed in the slots, lacking a pressing device. During welding, the welding device will touch the joints, easily causing the joints to loosen, resulting in an unsatisfactory welding effect. At the same time, the iron pipe also lacks a corresponding pressing device. In order to try to prevent the joints from loosening during welding, the size of the slots needs to be designed to match the joints better, that is, the outer wall of the joints needs to be firmly clamped by the slots. This makes it difficult to insert and remove the joints, and it is also easy to scratch the joints. Summary of the Utility Model
[0004] In view of the defects of the above - mentioned existing technology, the purpose of the utility model is to provide a double - assembled pipe fitting tooling fixture.
[0005] The technical solution of the utility model is: The double - assembled pipe fitting tooling fixture includes a base. A tooling main body is fixed at the front - end position of the top of the base. It also includes two first pressing devices for pressing down the joints and a second pressing device for pressing down the iron pipe. The structures of the first pressing device and the second pressing device are the same. The two first pressing devices are respectively fixed at the left and right ends of the base, and the second pressing device is fixed at the middle position of the rear end of the base. Both ends of the tooling main body have a slot for placing the joints. The first pressing device includes a bracket fixed on the top of the base, a movable rod rotatably connected to the upper end of the bracket, and a screw rod installed on the movable rod and slidably matched with the movable rod in the left - right direction. A first pressing head is fixed at the lower end of the screw rod, and the first pressing head is located above the joint.
[0006] Further, the tooling body includes a cross bar extending horizontally, and a first vertical bar and a second vertical bar are perpendicularly connected to both the left and right ends of the cross bar. A clamping groove is formed between the first vertical bar and the second vertical bar, and the front end and the upper end of the clamping groove are open.
[0007] Further, the rear ends of both second vertical bars each have an arc-shaped groove, and the left and right ends as well as the upper end of the arc-shaped groove are open. The left and right ends of the iron pipe are adapted to be inserted into the two arc-shaped grooves.
[0008] Further, the first pressing device further includes a connecting rod and a handle. The lower end of the handle is hinged to the middle of the bracket, the lower end of the connecting rod is fixedly connected to the movable rod, the middle of the handle is fixedly connected to the connecting rod, and the end of the movable rod away from the screw is hinged to the upper end of the bracket.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] To understand the technical solution of the present utility model more intuitively and comprehensively, the non-limiting feature description is as follows in combination with the attached drawings of the present utility model:
[0017] As Figure 1 — Figure 3 shown, the double-barrel pipe fitting tooling fixture includes a base 1, a tooling main body 2 is fixed at the front end position of the top of the base 1. It further includes two first pressing devices 3 for pressing down the connectors (not shown in the figure) and a second pressing device 4 for pressing down the iron pipes (not shown in the figure). The structures of the first pressing device 3 and the second pressing device 4 are the same. The two first pressing devices 3 are respectively fixed at the left and right ends of the base 1, and the second pressing device 4 is fixed at the middle position of the rear end of the base 1. Both left and right ends of the tooling main body 2 have a slot 21 for placing the connectors. The first pressing device 3 includes a bracket 31 fixed on the top of the base 1, a movable rod 32 rotatably connected to the upper end of the bracket 31, and a screw 33 installed on the movable rod 32 and slidably matched with the movable rod 32 left and right. A first pressing head 34 is fixed at the lower end of the screw 33, and the first pressing head 34 is located above the connector. The front end of the second pressing device 4 is provided with a second pressing head 41, and the second pressing head 41 is located above the iron pipe. Both the first pressing head 34 and the second pressing head 41 are rubber heads.
[0018] As Figure 1 shown, the tooling main body 2 includes a cross bar 22 extending left and right. A first vertical bar 23 and a second vertical bar 24 are perpendicularly connected to both left and right ends of the cross bar 22. A slot 21 is formed between the first vertical bar 23 and the second vertical bar 24. The front end and the upper end of the slot 21 are open, facilitating the insertion of the connector.
[0019] As Figure 1 shown, in order to stably place the iron pipe, both rear ends of the two second vertical bars 24 have an arc-shaped groove 241. The left and right ends and the upper end of the arc-shaped groove 241 are open, and the left and right ends of the iron pipe are inserted into the two arc-shaped grooves 241.
[0020] As Figure 3 shown, the first pressing device 3 further includes a connecting rod 35 and a handle 36. The lower end of the handle 36 is hinged to the middle part of the bracket 31. The lower end of the connecting rod 35 is fixedly connected to the movable rod 32. The middle part of the handle 36 is fixedly connected to the connecting rod 35. The end of the movable rod 32 away from the screw 33 is hinged to the upper end of the bracket 31. After rotating the handle 36, the movable rod 32 can be driven to rotate. As Figure 3 shown, at this time, the position of the first pressing head 34 can press on the connector. When the connector needs to be removed, rotate the handle 36 to the left, and the first pressing head 34 will be lifted.
[0021] As Figure 3As shown, a sliding hole 321 that penetrates up and down and extends left and right is provided on the movable rod 32. The screw rod 33 extends up and down through the sliding hole 321 and is in left and right sliding fit with the sliding hole 321.

The screw rod 33 passes through the first cushion block 37 and the second cushion block 38. The first nut 39 is screwed on the upper end of the screw rod 33 and presses on the top of the first cushion block 37. The second nut 3A is screwed on the lower end of the screw rod 33 and presses on the bottom of the second cushion block 38. After loosening the first nut 39 and the second nut 3A, the screw rod 33 can not only move left and right, but also move up and down.
[0022] For the double-unit pipe fitting tooling fixture provided by the present utility model, the first pressing device 3 can be used to press the joint, and the second pressing device 4 can be used to press the iron pipe (since the structure of the second pressing device 4 is the same as that of the first pressing device 3, only the installation positions are different. The first pressing device 3 is installed along the left and right direction, and the second pressing device 4 is installed along the front and back direction, so the structure of the second pressing device 4 will not be specifically described), so that the iron pipe is not easy to shake when welded to the joint;
[0023] The screw rod 33 of the present utility model can be adjusted up and down and left and right, and can be used with double-unit pipe fittings of different sizes. Specifically, the tooling main body 2 can be designed to be detachable and replaceable. According to double-unit pipe fittings of different sizes, the tooling main body 2 is selected. Therefore, it is extremely important that the screw rod 33 can be adjusted up and down and left and right, and the position of the first pressing head 34 can be adjusted according to the specific position of the joint. The adjustment method of the second pressing head 41 is the same.
[0024] Certainly, the above is only the preferred embodiment of the present utility model, and thus does not limit the patent scope of the present utility model. All simple modifications and equivalent structural changes made by using the specification and drawings of the present utility model should be equally included in the patent protection scope of the present utility model.
