Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of thin-walled box welding equipment, and in particular to a rotary tooling for welding large thin-walled boxes. Background Technology
[0002] The large, thin-walled box is 6500mm long with a maximum cross-sectional size of 588×585mm. It requires straightness of no more than 2mm and has very strict requirements for internal and external clearances and airtightness. Due to the large size of the box, personnel cannot reach the welding site, and the welded box is prone to deformation and air leakage. Currently, similar products on the market are difficult to weld and prone to rework. There is no effective and better way to solve the corresponding problems. Furthermore, due to the special nature of the product, there is currently no similar tooling on the market. Utility Model Content
[0003] This invention proposes a rotating fixture for welding large thin-walled boxes, which solves the problem that large thin-walled boxes cannot be rotated and welding operations are difficult.
[0004] The technical solution of this utility model is implemented as follows: A rotating tooling for welding large thin-walled boxes includes a first support and a second support. A counterweight is fixed on both the first support and the second support. An active clamping component is provided on the first support. The active clamping component is driven to rotate by a motor. A rotating driven clamping component is provided on the second support. The active clamping component and the driven clamping component are arranged facing each other at intervals. Both the active clamping component and the driven clamping component include a rectangular rotating frame. Countersunk screws are screwed at intervals on each side wall of the rectangular rotating frame.
[0005] Furthermore, both the first and second supports include a base, with a vertical support frame fixed to the upper end of the base. The vertical support frame includes a vertical support plate, with vertical rods fixed to both ends of one side of the support plate. A horizontal rod is fixed to the lower end of each vertical rod, and the horizontal rod is fixedly connected to the base. Diagonal braces are fixed between the vertical rods and the horizontal rods. Counterweights are fixed to the base at both ends of the support plate, and a bearing connecting sleeve is fixed to the other side of the support plate. The rectangular rotating frame is in a cantilevered state. The structural design of the vertical support frame ensures that the rectangular rotating frame remains vertical and does not tilt during use.
[0006] Furthermore, the rectangular rotating frame includes a mouth frame, with a cross-shaped component fixed to the side of the mouth frame near the corresponding support. Countersunk screws are screwed onto the side wall of the mouth frame. A driven shaft is fixed to the side of the cross-shaped component away from the countersunk screws. One end of the driven shaft is connected to a bearing connecting sleeve via a self-aligning roller bearing, and the other end is fixedly connected to the cross-shaped component. This rectangular rotating frame design ensures its supporting strength while reducing its overall weight, facilitating motor-driven rotation.
[0007] Furthermore, a driven gear is fixed on the driven shaft of the first support, and a motor-driven driving gear is provided on the base, with the driving gear and the driven gear meshing.
[0008] Furthermore, the motor is fixed on the first support, and the motor is connected to the drive shaft through a double diaphragm coupling. The drive shaft rotates through the corresponding support partition and is fixed with a drive gear, which is located above the driven gear.
[0009] Furthermore, the motor is located on a base between the two diagonal braces.
[0010] The beneficial effects of this utility model are:
[0011] This utility model's rotating fixture solves the problem of difficult welding operations and inability to rotate large thin-walled boxes by placing the end of a large thin-walled box inside a rectangular rotating frame and securing it with countersunk screws. The user turns on the motor, which drives the rectangular rotating frame to rotate, and the rectangular rotating frame drives the large thin-walled box to rotate. Furthermore, both the first and second supports are equipped with counterweights to prevent the supports from tipping over and ensure the stability of the support. Attached Figure Description
