[0019] The following is a more detailed description of a positioning and clamping tool for T-row welding of the utility model in conjunction with a schematic diagram, in which a preferred embodiment of the utility model is shown. It should be understood that those skilled in the art can modify the utility model described herein and still achieve the beneficial effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the utility model.

[0020] like Figure 1 As shown, a positioning and clamping tool for T-row welding includes a tooling platform 1, a pressure block 4, a cushion block 5, an oil pump 6, a locking pin 74, a backing 7 and a clamping clamp 73.

[0021] Among them, the number of T rows, pressure blocks 4, cushion blocks 5, oil pumps 6, locking pins 74, backings 7 and clamping clips 73 is set as needed. The utility model sets two T rows, and each T row is equipped with three cushion blocks 5, one oil pump 6, and four backings 7. Each backing 7 is provided with a locking pin 74, and three backings 7 are provided with clamping clips 73. The assembly structure of two T rows when welded is the same. The positioning and clamping tooling of the utility model is described in detail below through a single T row.

[0022] The T-row to be welded includes a web 2 and a face plate 3, wherein the web 2 and the face plate 3 are perpendicular to each other, wherein the web 2 is placed horizontally and the face plate 3 is placed vertically. During welding, the connection between the web 2 and the face plate 3 is welded.

[0023] The web 2 and the panel 3 are both placed on the upper surface of the tooling platform 1. Since the web 2 needs to be welded to the middle of the panel 3, there is space between the web 2 and the upper surface of the tooling platform 1. Therefore, three pads 4 are respectively arranged between the web 2 and the tooling platform 1, and are respectively located at the left, middle and right lower part of the web 2 to support the web 2 and reach the corresponding horizontal height.

[0024] The left end of the web 2 is abutted by a backrest 7 to achieve assembly positioning. Similarly, the back side of the panel 3 (i.e., the side facing away from the web 2) is abutted by three backrests 7, and cooperates with the preset oil pump 6 set on the front side of the web 2 (the side facing away from the panel 3) to achieve clamping of the T row in the front and rear directions. The setting of the oil pump 6 can also play a role in designing the welding reverse deformation amount and controlling the welding deformation of the T row.

[0025] Furthermore, three clamping clips 74 are respectively arranged on three backrests 7 arranged on the back side of the panel 3, referring to Figure 2 , the backrest 7 is an L-shaped backrest, and the clamping frame 73 is a Z-shaped clamping clamp. The backrest 7 includes a baffle plate 72 and a fixing plate 71 which are integrally connected, wherein the tail end surfaces of the fixing plate 71 and the clamping clamp 73 are provided with a plurality of through holes at equal intervals, and the through holes match with the preset through holes of the tooling platform 1. A U-shaped through hole is provided on the front side surface of the baffle plate 72 of the backrest 7, and the head end of the clamping clamp 73 passes through the U-shaped through hole, and abuts against the upper end surface of the panel 3 through the bottom surface, and the clamping clamp 73 is fixed to the backrest 7 and the tooling platform 1 through the locking pin 74 and the through hole. The setting of the clamping clamp 73 realizes the welding deformation caused by the upward force generated during T-row welding.

[0026] Furthermore, a scale 75 is provided on the side of the baffle 72 of each backrest 7 to check whether the horizontal line of the panel 3 and the scale line 75 on the baffle 72 are consistent with the theory. If not, fine adjustment can be performed.

[0027] Located above the pad 5, a pressure block 4 is arranged on the upper surface of the web 2. The utility model is arranged to weld two T-rows at the same time. The two T-rows are arranged oppositely, that is, the two webs 2 are arranged adjacently. The two ends of the pressure block 4 are respectively placed above the two webs 2. The number of the pressure blocks 4 is set to three, and they are all located above the pad 5. The web 2 is connected and fixed to the tooling platform 1 by bolts. The web 2 of the utility model controls the upward and downward forces generated during welding through the pressure block 4 and the pad 5, thereby realizing deformation control in this direction.

[0028] If a T row is welded separately, the web 2 is pressed and fixed by bolts through the pressing block 4 or the machine tool pressing plate in conjunction with the triangular plate.

[0029] The use of a positioning clamping tool for T-row welding of the utility model comprises the following steps:

[0030] Step 1: When the web 2 and the face plate 3 of the T row are welded, the web 2 is suspended in the air. A cushion block 5 is preset under the web 2 according to the length of the T row to play a supporting role. There is a positioning backrest 7 at one end of the tooling platform 1. The web 2 stops after it is in place to ensure that the assembly positioning position is consistent each time.

[0031] Step 2: The three backrests 7 are relatively fixed on the sides of the tooling platform 1, and the panel 3 is inserted and positioned.

[0032] Step 3: Check whether the horizontal line of panel 3 and the scale line 75 on backrest 7 are consistent with the theory, and fine-tune them.

[0033] Step 4: Place two T rows at the same time and clamp and fix them with three pressing blocks 4.

[0034] Step 5: Design the welding reverse deformation through the oil pump 6 to control the T-row welding deformation.

[0035] Step 6: Perform welding. If the T-row is mass-produced, only three pressing blocks 4 need to be moved to remove and install the T-row, which is convenient and fast.

[0036] The above are only preferred embodiments of the present invention and do not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, may make any equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which shall be deemed as the content of the technical solution of the present invention and still fall within the protection scope of the present invention.
