[0023] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0024] Embodiment 1: Refer to Figures 2 - 5 , a welding tool for a direction seat, which includes a support 1, a positioning block 2, a stepped pin 3, a pressing head 4 and a presser 5;

[0025] Among them, the support 1 has a flat plate 1-1 and a side plate 1-2; the lower end of the side plate 1-2 is fixed integrally with the flat plate 1-1.

[0026] Among them, the positioning block 2 and the stepped pin 3 are both fixed on the upper surface of the flat plate 1-1; the pressing head 4 is located above the stepped pin 3, and the presser 5 is fixedly arranged on the side plate 1-2 and can make the pressing head 4 move downward to press tightly;

[0027] Among them, the positioning block 2 is provided with a U-shaped opening 2-1 for the ear N-1 of the lower cover N to be inserted.

[0028] Among them, the stepped pin 3 has a lower shaft section 3-1, a stepped surface 3-2 and an upper shaft section 3-3. Specifically, the outer diameter of the lower shaft section 3-1 is larger than the outer diameter of the upper shaft section 3-3; the outer diameter of the upper shaft section 3-3 is in clearance fit with the inner diameter of the upper tube M and is concentrically positioned with each other; the central hole N-2 of the lower cover N is the same as the inner diameter of the upper tube M.

[0029] Among them, the upper shaft section 3-3 is used to be inserted into the lower end of the inner hole of the upper tube M; the stepped surface 3-2 is used to support the inner surface of the lower cover N; the lower end of the pressing head 4 is provided with a flat cylinder 4-1 for pressing the two semi-circular grooves M-1 of the upper tube M.

[0030] Refer to Figure 4 , specifically, the central direction (i.e., the X direction) of the flat cylinder 4-1 and the radial direction (i.e., the Y direction) of the U-shaped opening 2-1 where the stepped pin 3 is located are perpendicular to each other in three-dimensional space.

[0031] In this embodiment, the presser 5 adopts a clamp. Specifically, the clamp adopts the CH-304 model and can be purchased from Jiagang Company. During clamping, the pressing head 4 can be displaced downward or upward by operating the clamp to achieve pressing or loosening.

[0032] Furthermore, the flat plate 1-1 is provided with a strip-shaped fixing hole 1-11. The strip-shaped fixing hole 1-11 on the support 1 can be detachably fixed on the workbench through bolts. At the same time, the tooling can be detached and the working position can be adjusted.

[0033] Its working principle is as follows: Refer to Figures 6 - 9, when performing welding clamping, first place the lower cover N on the stepped pin 3. The stepped surface 3-2 contacts the inner surface of the lower cover N and is used to horizontally support the inner surface of the lower cover N. The upper shaft section 3-3 is concentrically positioned with the central hole of the lower cover N. The lug N-1 of the lower cover N is inserted into the U-shaped opening 2-1 on the positioning block 2 to be restricted from rotating, so as to position the direction of the lug N-1 of the lower cover N, that is, the Y direction (see Figures 8 - 9 ); then sleeve the upper pipe M on the upper shaft section 3-3. The inner hole of the upper pipe M is concentrically positioned with the upper end of the upper shaft section 3-3 to ensure that the central hole of the lower cover N is concentric with the inner hole of the upper pipe M (see Figure 7 ); then operate or start the press 5 to work. The press 5 makes the flat cylinder 4-1 of the pressure head 4 move downward and press the two semi-circular grooves M-1 of the upper pipe M until they are completely fitted after being pressed. At this time, the directions of the two semi-circular grooves M-1 on the upper pipe M (i.e., the X direction) and the direction of the lug N-1 of the lower cover N (i.e., the Y direction) are perpendicular to each other. At the same time, the lower cover N and the upper pipe M are pressed and concentrically held (see Figures 6 - 8 ).

[0034] Therefore, the tooling of the present utility model can realize respectively positioning the lower cover N and the upper pipe M of the direction seat before welding and keeping their relative positions fixed. The lower cover N and the upper pipe M are concentrically positioned and fixedly constrained. At the same time, the lug N-1 of the lower cover N and the distribution directions of the two semi-circular grooves M-1 on the upper pipe M are perpendicular to each other (i.e., the X-Y direction), which can ensure the welding accuracy and quality.

[0035] In addition, when clamping the lower cover N and the upper pipe M, the operation is simple, and the positioning and pressing are very convenient. At the same time, when welding, the welding torch will not interfere when performing circumferential welding at the contact position between the upper pipe M and the lower cover N, which meets the technological requirements, is safe to operate, and can improve the welding work efficiency.

[0036] Therefore, when welding the lower cover N and the upper pipe M of the above-mentioned direction seat to each other, it is necessary to solve the technical problems of how to concentrically position and fix the upper pipe M and the lower cover N, and at the same time, it is also necessary to ensure that the distribution directions of the lug N-1 of the lower cover N and the two semi-circular grooves M-1 on the upper pipe M are perpendicular to each other.

[0037] In addition, after welding is completed, just operate or start the press to work and make the pressure head 4 move upward to a certain height, that is, the reset height, to realize loosening the welded workpiece, then the direction seat can be pulled out upward easily, and the unloading of the workpiece is very convenient, taking less time and being safe to operate.

[0038] Embodiment 2: This embodiment is basically the same as Embodiment 1, the difference is that:

[0039] See Figure 10 , in this embodiment, the press 5 adopts a cylinder (i.e., a telescopic cylinder).

[0040] When pressing and releasing, the cylinder can drive the indenter 4 to move downward or upward, thereby achieving automatic pressing or releasing, without manual operation, which is more labor-saving.

[0041] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field according to the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art shall fall within the protection scope determined by the claims.
