[0032] Reference Figure 3 and Figure 4 The shovel component 700 includes a shovel plate 710, an attachment plate 720, and a shovel handle 730. The attachment plate 720 is welded to the top front side of the shovel plate 710. The top of the shovel plate 710 is bent to have a support portion 711. One end of the shovel handle 730 is inserted between the attachment plate 720 and the shovel plate 710. The top edge of the attachment plate 720 and the support portion 711 together clamp the shovel handle 730, and both the top edge of the attachment plate 720 and the support portion 711 are welded to the shovel handle 730.

[0033] Reference Figures 1 to 4 According to an embodiment of the present invention, a welding fixture is used to position a shovel plate 710, an attachment piece 720, and a shovel handle 730, and to adjust the position of the shovel plate 710, the attachment piece 720, and the shovel handle 730 after positioning. The welding fixture includes a frame 100, a support plate 200, a positioning component 300, and a drive component 400.

[0034] The support plate 200 has a first mounting part 210 and a second mounting part 220 arranged opposite to each other. The second mounting part 220 is rotatably connected to the frame 100. The support plate 200 and the second mounting part 220 are used to support the bottom and rear side of the shovel plate 710, respectively. The positioning component 300 is provided on the first mounting part 210. The positioning component 300 is used to clamp the mounting piece 720 and the shovel plate 710 together with the second mounting part 220, so that the mounting piece 720 abuts against the top front side of the shovel plate 710, and the top edge of the mounting piece 720 and the support part 711 jointly clamp the shovel handle 730. The drive component 400 is provided on the frame 100. The drive component 400 is connected to the second mounting part 220 for transmission. The drive component 400 is used to drive the second mounting part 220 to rotate, so as to adjust the angle between the support plate 200 and the frame 100, so as to change the position of the clamped shovel plate 710, the mounting piece 720 and the shovel handle 730.

[0035] Understandably, the positioning component 300 is used together with the second mounting part 220 to clamp the mounting plate 720 and the shovel plate 710, so that the mounting plate 720 presses against the top front side of the shovel plate 710, and the top edge of the mounting plate 720 and the support part 711 jointly clamp the shovel handle 730, thereby positioning the shovel plate 710, the mounting plate 720 and the shovel handle 730; the driving component 400 is used to drive the second mounting part 220 to rotate, so as to adjust the angle between the support plate 200 and the frame 100, thereby changing the position of the clamped shovel plate 710, the mounting plate 720 and the shovel handle 730, thereby adjusting the position of the shovel plate 710, the mounting plate 720 and the shovel handle 730 after positioning.

[0036] With the above structure, the support plate 200, positioning component 300 and drive component 400 provided on the frame 100 cooperate with each other to position the shovel plate 710, the mounting plate 720 and the shovel handle 730, and to adjust the position of the shovel plate 710, the mounting plate 720 and the shovel handle 730 after positioning. The above process does not require manual intervention, so it can reduce the deviation between the welding position of one shovel component 700 and the welding position of the other shovel component 700.

[0037] The positioning component 300 includes a first driving component 310 and a first pushing component 320.

[0038] Reference Figure 1 and Figure 2 The first driving member 310 is disposed on the first mounting part 210, and the first push block 320 is connected to the output end of the first driving member 310. The first push block 320 is located between the first mounting part 210 and the second mounting part 220. The first driving member 310 is used to drive the first push block 320 to move so that the first push block 320 and the second mounting part 220 jointly clamp the mounting plate 720 and the shovel plate 710. The first driving member 310 can be configured as a cylinder, a hydraulic cylinder, or an electric push rod, etc.

[0039] The first pusher 320 and the second mounting part 220 together clamp the mounting plate 720 and the shovel plate 710. That is, the first pusher 320 abuts against the front side of the mounting plate 720, and the second mounting part 220 abuts against the rear side of the shovel plate 710. The first pusher 320 pushes the mounting plate 720 so that it presses against the top front side of the shovel plate 710. The top edge of the mounting plate 720 pressing against the shovel plate 710 and the support part 711 of the shovel plate 710 together clamp the shovel handle 730. At this time, the production personnel can weld the mounting plate 720 and the shovel plate 710 together at the preset position, and weld the top edge of the mounting plate 720 and the shovel handle 730 together.

[0040] It is understandable that the aforementioned preset positions are the positions of the shovel plate 710, the mounting plate 720, and the shovel handle 730 after being positioned by the production personnel through the drive component 400. These positions are the ones that the production personnel are accustomed to and that are convenient for welding work.

[0041] In some embodiments, the positioning component 300 may include only the first drive member 310, the output end of which is used to clamp the mounting plate 720 and the spade plate 710 together with the second mounting part 220.

[0042] In this embodiment, refer to Figure 1 and Figure 2 The first mounting portion 210 is provided with a second driving member 510, and the output end of the second driving member 510 is provided with a second push block 511. The second push block 511 is located between the first mounting portion 210 and the second mounting portion 220. The second push block 511 is provided with a clearance notch 511A for the first push block 320 to pass through. The second driving member 510 is used to drive the second push block 511 to move so that the second push block 511 and the second mounting portion 220 jointly clamp the shovel plate 710. The second driving member 510 can be configured as a cylinder, a hydraulic cylinder, or an electric push rod, etc.

[0043] The second pusher 511 and the second mounting part 220 together clamp the shovel plate 710, that is, the second pusher 511 and the second mounting part 220 respectively abut against the front and rear sides of the shovel plate 710.

[0044] With the above structure, the shovel plate 710 can be positioned before the first push block 320 and the second mounting part 220 jointly clamp the mounting piece 720 and the shovel plate 710, that is, before positioning the mounting piece 720 and the shovel plate 710, so as to facilitate the placement of the mounting piece 720 and the shovel handle 730.

[0045] When positioning the shovel plate 710 first, in order to improve the positioning effect of the shovel plate 710, refer to Figure 1 and Figure 2The first mounting part 210 is provided with a fourth driving member 520, the output end of which is used to clamp the bottom of the shovel plate 710 together with the second mounting part 220. The fourth driving member 520 can be configured as a cylinder, a hydraulic cylinder, or an electric push rod, etc.

[0046] The output end of the fourth drive member 520 is used to clamp the bottom of the shovel plate 710 together with the second mounting part 220, that is, the output end of the fourth drive member 520 and the second mounting part 220 respectively abut against the front and rear sides of the bottom of the shovel plate 710.

[0047] The first pusher 320 is connected to the output end of the first drive unit 310, and the output end of the second drive unit 510 is provided with a second pusher 511. For details, refer to... Figure 1 and Figure 2 The first mounting portion 210 has two guide rods 600 inserted through it. The two ends of one guide rod 600 are connected to the output ends of the first push block 320 and the first drive member 310, respectively, and the two ends of the other guide rod 600 are connected to the output ends of the second push block 511 and the second drive member 510, respectively. The first mounting portion 210 has two through holes (not shown in the figure) arranged vertically, and the two guide rods 600 are inserted through the two through holes in a one-to-one correspondence.

[0048] The above structure can improve the movement stability of the first push block 320 and the second push block 511.

[0049] The second mounting part 220 is rotatably connected to the frame 100. For details, please refer to... Figure 1 and Figure 2 The frame 100 is provided with two opposing vertical frames (not shown in the figure). The second mounting part 220 is provided with a pivot 221. The two ends of the pivot 221 are rotatably connected to the two vertical frames through bearings. That is, the second mounting part 220 is rotatably connected to the frame 100 through the pivot 221. The drive assembly 400 is connected to the pivot 221 for transmission.

[0050] In this embodiment, a gear 221A is sleeved on one end of the pivot member 221, and the drive assembly 400 includes a third drive member 410 and a rack 420.

[0051] Reference Figure 2The third drive unit 410 is mounted on the frame 100. A rack 420 is connected to the output end of the third drive unit 410. The rack 420 meshes with a gear 221A. The third drive unit 410 drives the rack 420 to move, thereby rotating the pivot 221 via the gear 221A, which in turn rotates the second mounting portion 220 to adjust the angle between the support plate 200 and the frame 100, thus changing the positions of the clamped shovel plate 710, the mounting plate 720, and the shovel handle 730. The third drive unit 410 can be a cylinder, a hydraulic cylinder, or an electric push rod, etc.

[0052] With the above structure, on the one hand, the angle between the support plate 200 and the frame 100 can be adjusted to facilitate the welding connection of the support part 711 and the shovel handle 730 by production personnel; on the other hand, the rack 420 meshes with the gear 221A to lock the second mounting part 220.

[0053] In some embodiments, a gear 221A is sleeved on one end of the pivot member 221, and the drive assembly 400 includes a third drive member 410 and a drive wheel. The third drive member 410 is disposed on the frame 100, and the output end of the third drive member 410 is connected to the drive wheel, which meshes with the gear 221A. The third drive member 410 is configured as a motor.

[0054] To improve the stability of rack 420 during movement, refer to Figure 2 The frame 100 is provided with a guide groove 110, and the rack 420 is slidably disposed in the guide groove 110.

[0055] In this embodiment, refer to Figure 1 and Figure 2 The support plate 200 is provided with a counterweight 230, which is located on the side of the second mounting part 220 away from the first mounting part 210.

[0056] Through the aforementioned mechanism, the counterweight 230 can reduce the meshing load between the rack 420 and the gear 221A.

[0057] To avoid collision between the support plate 200 and the frame 100, refer to Figure 1 and Figure 2 The frame 100 is equipped with two control switches 120, which are located on opposite sides of the rotation axis of the second mounting portion 220. The control switches 120 are electrically connected to the third drive member 410. The drive assembly 400 drives the second mounting portion 220 to rotate. When the support plate 200 abuts against the corresponding control switch 120, the control switch 120 stops the third drive member 410, and the rack 420 stops moving to lock the second mounting portion 220 via gear 221A. The control switches 120 are configured as microswitches.

[0058] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
