Description

Technical Field

[0001] The utility model relates to a vehicle frame welding tool, belonging to the technical field of vehicle frame welding. Background Art

[0002] Garbage trucks are used to collect, load and transport domestic waste. They can compress and crush the loaded garbage to increase its density and reduce its volume, greatly improving the efficiency of garbage collection and transportation. The new type of garbage truck has the characteristics of reliable quality, low failure rate, easy maintenance and low operating costs.

[0003] During the manufacturing process, a garbage truck is composed of a frame and a carriage mounted on the frame. During the manufacturing process of the frame, the parts of each part of the frame need to be welded and assembled. The welding and assembly process of the frame is generally carried out on a work platform. The frame is first placed on the platform for welding. When welding different parts of the frame, the operator is required to manually adjust the position of the frame. The operation is difficult and labor-intensive, resulting in low production efficiency.

[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0009] A multi-rod cylinder is respectively installed on the second end of the left support beam and the second end of the right support beam, and the second clamping plate is installed on the telescopic end of the multi-rod cylinder.

[0010] Furthermore, the position of the first clamping plate on the left support beam and the right support beam is adjustable.

[0011] Furthermore, polyurethane pads are provided on the inner valley bottoms of the first and second plywood to increase friction with the bicycle frame.

[0012] Furthermore, left plates are horizontally fixed on both sides of the left support beam, and right plates are horizontally fixed on both sides of the right support beam. The left plate and the right plate are fixed together facing each other, and a long hole is provided in the horizontal direction on the upper edge of the right plate, and bolts are installed on the long hole, and the left plate and the right plate are fixed together by the bolts.

[0013] Furthermore, it also includes a support frame, which includes two vertically arranged mounting plates, and the left turntable and the right turntable are rotatably mounted on the corresponding mounting plates respectively.

[0014] Furthermore, the back side of the left turntable is rotatably mounted on the left mounting plate via a toothless slewing support, and the back side of the right turntable is rotatably mounted on the right mounting plate via a toothed slewing support.

[0015] Furthermore, a lead screw is rotatably installed on the outer side of the left support beam, and a first bevel gear is rotatably installed on the left turntable. The inner hole of the first bevel gear is threadably connected to the lead screw through a thread, and the first bevel gear is matched with the second bevel gear, and the second bevel gear is driven by the first motor.

[0016] Furthermore, the toothed slewing bearing is meshed with a driving gear for transmission, and the driving gear is driven by a second motor.

[0017] Compared with the prior art, the present invention has the following advantages after adopting the above technical solution:

[0019] 2. The second motor drives the right turntable to rotate through the toothed slewing bearing. The right turntable and the left turntable are connected by a sliding rod. The rotation of the right turntable and the left turntable can flexibly adjust the welding angle of the frame.

[0020] 3. The lead screw is rotatably connected to the left support beam, and a first bevel gear is rotatably installed on the left turntable. The inner hole of the first bevel gear is threadably connected to the lead screw through a thread. When the first bevel gear rotates forward and reverse, the thread cooperates to pull the lead screw to move left and right, thereby pulling the left support beam and the right support beam to move left and right, so that the left and right positions of the frame can be adjusted.

[0029] like Figure 1-4 As shown, the utility model provides a frame welding tool, including two coaxially arranged left turntables 2 and right turntables 3, two sliding rods 4 are installed in parallel between the left turntable 2 and the right turntable 3, and a left support beam 5 and a right support beam 6 are slidably installed on the two sliding rods 4. A first clamping plate 18 is installed at the first end of the left support beam 5 and the right support beam 6, and a second clamping plate 19 is installed at the second end of the left support beam 5 and the right support beam 6. The first clamping plate 18 and the second clamping plate 19 are perpendicular to the upper surfaces of the left support beam 5 and the right support beam 6;

[0030] A multi-rod cylinder 20 is installed on the second end of the left support beam 5 and the second end of the right support beam 6 respectively, and the second clamping plate 19 is installed on the telescopic end of the multi-rod cylinder 20.

[0031] When welding the frame, the frame is placed on the left support beam 5 and the right support beam 6, and the multi-rod cylinder 20 contracts, driving the second clamping plate 19 to move closer to the first clamping plate 18, thereby fixing the frame on the support beam. The position of the first clamping plate 18 on the left support beam 5 and the right support beam 6 is adjustable, so as to adapt to frames of different widths.

[0032] Polyurethane pads are provided at the inner valley bottoms of the first and second plywood plates 18 and 19 to increase friction with the bicycle frame.

[0033] A left side plate 7 is horizontally fixed to both sides of the left support beam 5, and a right side plate 8 is horizontally fixed to both sides of the right support beam 6. The left side plate 7 and the right side plate 8 are fixed together facing each other. A long hole 9 is provided in the horizontal direction on the right side plate 8. Bolts are installed in the long hole 9 to fix the left side plate 7 and the right side plate 8 together. The long hole 9 can be used to adjust the distance between the left support beam 5 and the right support beam 6 to accommodate different lengths of frames.

[0034] The present invention further comprises a support frame 1 , which comprises two vertically arranged mounting uprights 101 , and the left turntable 2 and the right turntable 3 are rotatably mounted on the corresponding mounting uprights 101 .
