Referring to fig. 1 and 2, the pressing locking assembly includes a lower pressing bar 830 installed on a side wall of the lifting disc 75, a plug 831 is installed on a lower end surface of the lower pressing bar 830, and a jack is formed on the connecting frame 820 and is in plug fit with the plug 831.
The connecting frame 820 is used for connecting the pull rod 815 and the driving plate 806, thereby simultaneously driving the pull rod 815 and the driving plate 806 to move upwards, after the frame 1 is placed and finished, the connecting frame 820 moves to the initial position under the action of the reset elastic force of the pull spring 804 and the push spring 816, the lifting disk 75 moves downwards, the lifting disk 75 drives the lower pressing strip 830 to move downwards, and the inserting column 831 on the lower pressing strip 830 is inserted into the inserting hole to lock the position of the connecting frame 820, thereby realizing the integrated locking function of the clamping mechanism 7 and the inserting and supporting positioning mechanism 8, and greatly improving the convenience of positioning and fixing the frame 1.
Referring to fig. 2, the connecting frame 820 and the driving plate 806 form a frame structure staggered from the welding position of the frame 1, so as to avoid shielding when the frame 1 is turned over and then subjected to scale welding.
Referring to fig. 1-6, in specific operation, the frame 1 after ordinary welding is placed on the clamping mechanism 7 and the inserting and supporting positioning mechanism 8, and the frame 1 is pre-positioned by the inserting and supporting positioning mechanism 8, so that the frame 1 obtains a pre-positioning locking effect of the position under the matching action of the supporting and fixing group 80 and the inserting and positioning group 81, the convenience of fixing the frame 1 is improved, and the accuracy of determining the welding seam position of the frame 1 is also improved.
After the inserting and positioning mechanism 8 is used for fixing the frame 1 in a preset position, the lifting disc 75 is driven to move downwards through the existing driving source (such as an electric sliding block, an air cylinder and the like), the lifting disc 75 drives the inclined supporting rod 73 to move towards the T-shaped column 5 through the pressing and locking group 76, the inclined supporting rod 73 drives the arc-shaped supporting seat 74 to move towards the side wall of the vertical section of the T-shaped column 5 until the three groups of clamping groups respectively clamp the main frame rod 10, the inclined rod 11 and the straight cylinder 12, the supporting guide rod 6, the inclined supporting rod 73 and the vertical section of the T-shaped column 5 form a triangular stable structure, so that the frame 1 is stably fixed in a high position, the firmness of the frame 1 during scale welding is improved, the scale welding aesthetic property is reduced due to shaking of the frame 1 is avoided, meanwhile, the lifting disc 75 drives the lower pressing strip 830 to move downwards, and the inserting column 831 on the lower pressing strip 830 is inserted into the inserting hole, so that the position of the connecting frame 820 is locked, and the integral locking function of the clamping mechanism 7 and the inserting and the positioning mechanism 8 is realized.
Then, the frame 1 is subjected to scale welding through the automatic scale welding mechanism 3, after the scale welding of one side of the frame 1 is finished, the rotating shaft drives the frame 1 to turn over 180 degrees under the driving action of an external driving source (such as a motor), and then the other side of the frame 1 is subjected to scale welding through the automatic scale welding mechanism 3, so that the convenience of scale welding of two sides of the frame 1 is improved.
