[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0029] Referring to Figures 1-5 , the present utility model discloses an auxiliary tooling for welding a T-shaped tool blade, which is mainly used for welding between the tool head 302 and the blade 303 of the T-shaped tool 300, aiming to reduce the labor intensity of workers and facilitate the welding process of the T-shaped tool 300. The structure of the T-shaped tool 300 is as shown in Figure 4 , and its structure includes a tool handle 301, a tool head 302, and a blade 303 arranged on the tool head 302 by welding.

[0030] In the embodiment of the present disclosure, as shown in Figure 1 , the auxiliary tooling for welding a T-shaped tool blade includes a base 100 and an extension arm 200. Among them, a support column 102 capable of linearly reciprocating sliding is arranged on the base 100, and a limit device 110 for restricting the sliding range of the support column 102 is provided; the length direction of the extension arm 200 is parallel to the vertical plane where the reciprocating sliding direction of the support column 102 is located. One end of the extension arm 200 is rotatably arranged at the upper end of the support column 102, and the other end is provided with an installation structure 202 for detachably installing the tool handle 301; a fixing device 104 for restricting the rotation of the extension arm 200 is arranged on the support column 102.

[0031] During use, as shown in Figure 5 , the tool handle 301 of the T-shaped tool 300 is fixed through the installation structure 202, and then the height position of the tool head 302 is adjusted by adjusting the angle between the extension arm 200 and the support column 102. The positional relationship between the tool head 302 and the heating coil 401 of the welding machine 400 is checked and the position of the tool head 302 is corrected. Then, the blade 303 to be welded is placed on the tool head 302 in a specific manner, the support column 102 is slid, so that the tool head 302 and the blade 303 to be welded are close to the heating coil 401, and the welding machine 400 controls the heating coil 401 to heat the connection between the blade 303 and the tool head 302 to complete the welding.

[0032] Among them, the connection between the tool handle 301 and the installation structure 202 is a detachable connection method. One is to facilitate replacing the welded T-shaped tool 300 for a new welding operation; the other is to facilitate loosening the tool handle 301 and rotating the tool head 302 to adjust a new welding position after one blade 303 on the tool head 302 is welded.

[0033] Among them, the support column 102 has a certain sliding range under the limitation of the limiting device 110. When the support column 102 is at the extreme position close to the heating coil 401 by adjusting the placement position of the base 100 or adjusting the limiting device 110, the relationship between the heating coil 401 and the tool head 302 is exactly at the optimal welding position. After welding is completed, the support column 102 can be moved away from the heating coil 401 to let the tool head 302 leave the coil position. At this time, the tool handle 301 can be loosened to adjust the tool head 302. Then, a new blade 303 to be welded is set. Without the obstruction of the heating coil 401, it is easier to operate. After setting, it is directly moved towards the heating coil 401. After moving to the extreme position, the preset optimal welding position is reached, and the welding of the new blade 303 can be started.

[0034] Such as Figure 2 , to support the sliding requirement of the support column 102, a sliding groove 101 is provided on the base 100, and the lower end of the support column 102 is slidably matched with the sliding groove 101. The sliding groove 101 is a T-shaped groove, and the lower end of the support column 102 is provided with a large-end structure (T-shaped) adapted to the sliding groove 101.

[0035] For the convenience of adjustment and application, the limiting device 110 includes a slider 111 arranged in the sliding groove 101 and slidably matched therewith. A first threaded hole 112 is provided on the slider 111, and a first screw 113 threadedly engaged therewith is arranged in the first threaded hole 112; rotating the first screw 113 can make the small end of the first screw 113 abut against the bottom of the sliding groove 101 to limit the sliding of the slider 111. Further, there are 2 sliders 111, which are respectively arranged on both sides of the support column 102.

[0036] Such as Figure 2 , a connecting hole 103 is provided at the upper end of the support column 102, and a connecting shaft 201 for rotational connection is arranged on the extension arm 200 and inserted into the extension hole; the fixing device 104 includes a second threaded hole 105 provided on the support column 102 and penetrating from one side to the connecting hole 103, and a second screw 106 is arranged in the second threaded hole 105. After loosening the second screw 106, the attitude of the extension arm 200 can be adjusted. After adjustment, rotating the second screw 106 can make the second screw 106 abut against the connecting shaft 201 to limit the rotation of the connecting shaft 201.

[0037] Further, to facilitate the adjustment of the extension arm 200, an installation block 107 is provided on the support column 102. A third threaded hole 108 (vertically arranged, with the aperture of the third threaded hole 108 parallel to the height direction of the support column 102) is provided on the installation block 107. The third threaded hole 108 is arranged below the connecting shaft 201, and the axis of the third threaded hole 108 deviates from the axis of the connecting shaft 201. A third screw 109 is arranged in the third threaded hole 108, and the upper end of the third screw 109 can support the lower side of the extension arm 200. As Figure 1 , on the premise of loosening the second screw 106, turning up the third screw 109 can push the extension arm 200 to swing upward, and turning down the second screw 106 can make the extension arm 200 swing downward, so that it is easier to adjust the cutter head 302 to be welded to a suitable height.

[0038] To design a better structure and solve the problem of detachable installation of the tool handle 301, as Figure 3 , the installation structure 202 includes a seat body 203 provided at one end of the extension arm 200 away from the support column 102. The seat body 203 is provided with a lower installation part 204 and an upper installation part 210 arranged on the opposite side of the lower installation part 204. A V-shaped groove 207 with an opening direction facing the upper installation part 210 is provided on the lower installation part 204. A stud 211 is provided on the upper installation part 210 and is threadedly connected thereto. A pressing block 212 is arranged between the stud 211 and the V-shaped groove 207; turning the stud 211 can push the pressing block 212 toward the V-shaped groove 207 by the end of the stud 211. When installing the tool handle 301, the tool handle 301 is arranged in the V-shaped groove, and the stud 211 can be used to push the pressing block 212 to cooperate with the V-shaped groove to fix the tool handle 301.

[0039] The installation structure 202 of the above structure has several advantages. One is that the fixing and loosening of the tool handle 301 are very convenient, and the other is that the repeated accuracy of repeatedly installing the tool handle 301 is very high.

[0040] Among them, for the convenience of manufacturing, the seat body 203 is annular. One side of the annular seat body 203 is the lower installation part 204, and the side opposite to the lower installation part 204 is the upper installation part 210. Further, as Figure 3 , the lower installation part 204 is provided with a groove 205 and a support block 206. The support block 206 is provided with the V-shaped groove 207 and an insertion block 208. The insertion block 208 is arranged on the back side of the V-shaped groove 207. The insertion block 208 is embedded in the groove 205, and a fourth screw 209 is arranged on the lower installation part 204 and is threadedly connected to the insertion block 208 after passing through the lower installation part 204. The fourth screw 209 fixes the support block 206 on the lower installation part 204.

[0041] Further, two guide rods 213 extending away from the V-shaped groove 207 are provided on the pressing block 212. The guide rods 213 are slidably matched with the upper mounting portion 210.
