Description

Technical Field

[0001] The present application relates to the technical field of forklift manufacturing, and in particular to a welding positioning device for a fork frame. Background Art

[0002] The fork is the most commonly used picking device of the forklift, which is also the origin of the forklift's name. The forklift is equipped with two forks shaped like the letter L. The horizontal section of the fork is the working part for placing the goods, and the vertical section is the supporting part. When the fork is produced, the fork frame needs to be welded.

[0003] The existing patent (publication number: CN219684422U) discloses a forklift fork frame welding device, including a base and a welding robot. A fixing frame is provided on the base, and a fixing mechanism is connected to the fixing frame. The fixing mechanism includes a fixing beam and two fixing blocks for clamping the fork frame. The fixing beam is provided with a plurality of positioning holes along its length direction. The fixing block is detachably connected to the fixing beam through bolts and positioning holes. The positions of different positioning holes are adapted to the sizes of different types of fork frames. After placing the various components of the fork frame on the fixing frame according to their configuration, the fork frame is adjusted to the middle position in the length direction of the fixing frame, and then the fixing block is fixed to the positioning hole corresponding to the fork frame model so that the fork frame is accurately fixed on the fixing frame. The positioning hole enables the fork frame to be accurately positioned, so that the fork frames of the same model are fixed on the fixing frame at the same position, and there is no need to calibrate the initial coordinate point of welding, which saves the calibration time of the welding robot. The present application has the effect of improving the welding efficiency of the fork frame.

[0004] The above-mentioned comparative document points out that the device adapts to different fork frames by adjusting the fixing block and the positioning holes in different positions. Therefore, the adjustment range is subject to certain limitations, and it is difficult for the positioning mechanism and the fork frame to fit tightly, so the tightness during fixation is low. Slight shaking may occur during the welding process, resulting in position deviation during welding, making it difficult to ensure the accuracy of welding, and the selectivity during fixation is limited.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a welding positioning device for a fork frame, comprising a base plate, the upper end of the base plate is rotatably connected to a rotating seat, the upper end of the rotating seat is fixedly connected to a supporting plate, one side of the upper end of the base plate is fixedly connected to two first fixed blocks, one side of the two first fixed blocks are fixedly connected to a first hydraulic rod, the ends of the two first hydraulic rods away from the first fixed block are fixedly connected to a support block, and the bottom ends of the two support blocks are fixedly connected to two sliding blocks.

The first hydraulic rod and the second hydraulic rod cooperate with each other to adjust the clamping claw to a suitable position and fix it to complete the welding. When the device clamps the substrate, the clamp can fit tightly with the substrate to prevent shaking during the welding process and improve the accuracy of welding.

[0009] Furthermore, the surface of the supporting plate is rotatably connected with four adjusting bolts.

[0010] Through the above scheme, the adjusting bolt is used to adjust the position of the clamp to adapt to different substrates

[0011] Furthermore, the four adjusting bolts are threadedly sleeved with a clamp on their outer surfaces.

[0012] Through the above solution, the clamp is used to clamp and fix the substrate.

[0013] Furthermore, two sliding blocks are slidably connected inside the two sliding grooves.

[0014] Through the above solution, the slide groove and the sliding block cooperate with each other to enable the supporting block to slide.

[0015] Furthermore, electromagnets are fixedly connected inside the two clamping jaws.

[0017] Furthermore, a second fixing plate is fixedly connected to one side of the base plate, and a welding robot arm is fixedly connected to the upper end of the second fixing plate.

[0018] Through the above scheme, the welding robot arm is an existing structure, which is used to replace manual welding of objects that need to be welded, improve welding accuracy, and increase welding efficiency.

[0019] Furthermore, the clamps are all higher than the supporting plate.

[0020] Through the above solution, the substrate is placed on the supporting plate.

[0021] Furthermore, four brackets are fixedly connected to the bottom end of the base plate.

[0022] Through the above solution, four brackets are used to support the device as a whole.
