Compared with the prior art, the beneficial effect of the present invention is that the main working object of the present invention is a T-shaped workpiece that needs to be centered and clamped, and the whole device can be installed on different workbenches through the U-shaped mounting base. When working, press the screw to fix the web on the support platform, the servo motor drives the lifting platform to move up and down through the screw, so that the wing and the web are centered, and the wing is clamped by the hydraulic cylinder to push the lifting platform to move inward to align the wing and the web. The webs are aligned and clamped. The invention mainly solves the problem of difficult centering when welding T-shaped workpieces. Compared with the existing centering methods, it has the characteristics of simple operation, reliable work, small workload and low cost, and the device is simple in structure and easy to disassemble. , strong adaptability, easy to use, can reduce labor intensity and improve production efficiency. It is suitable for welding workshops to solve T-shaped workpiece clamping, straightening and welding operations, which can improve efficiency.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

1 to 4, the present invention is a T-shaped workpiece centering device, which mainly consists of a mounting base 1, a hydraulic cylinder mounting base 2, a web clamping hydraulic cylinder 3, a web support table 4, a rotating pressure plate 5, and a pressure plate. Tightening screw 6, motor 7, motor mounting seat 8, coupling 9, wing plate lifting platform 10, lifting platform base 11, lead screw 12, wing plate clamping hydraulic cylinder 13, hydraulic cylinder mounting seat 14, guide rail 15, sliding Block 16 and so on.

The rotating pressure plate 5 is tapped with threads, and is matched with the compression screw 6 through the threads. The rotary pressure plate 5 and the compression screw 6 are fixed on the web support platform 4. The web support platform 4 is a casting, and it is designed to be hollow in order to reduce its weight. form.

As can be seen from FIGS. 1 and 2 , the motor 7 is mounted on the motor mount 8 , and the motor mount 8 is fixed on the base 11 of the lifting platform. The output rotating shaft of the motor is connected with the lead screw 12 through the flange coupling 9, and the two ends of the lead screw 12 are symmetrically arranged with angular contact ball bearings to share the gravity. The wing plate lifting platform 10 has a thread on the upper tap, cooperates with the leading screw 12 by the thread, and is designed with a reinforcing rib plate, and the wing plate lifting platform 10 is installed on the lifting platform base 11 . Motor 7 rotates and can drive leading screw 12 to rotate, and the wing plate elevating platform 10 that cooperates with it just can move up and down along elevating platform base 11. There is a supporting platform stretching out at the front end of the wing plate lifting platform 10, which is used to lift the panel.
