[0011] Figure 2 It is a top view of the present utility model. DETAILED DESCRIPTION
[0012] The present invention is described in detail below in conjunction with specific embodiments:
[0013] like Figure 1 and Figure 2 The illustrated welding fixture for supporting a car seat frame includes a base 1, a guide platform 2, a limit platform 20, a guide rod 21, a spring 22, a first pressure block 23, an anti-slip ring 25, a pressure plate 3, a linear telescopic cylinder 5, a slider 51, a cylinder seat 52 and a hinge 6. A positioning groove 11 is provided on the top of the base 1. The limit platform 20 and the guide platform 2 are fixedly installed at the upper and lower ends of the base 1. The guide rod 21 is slidably installed in the guide platform 2. The spring 22 is sleeved on the guide rod 21. The first pressure block 23 is fixedly installed on the guide On the platform 2, the two ends of the spring 22 act on the first pressure block 23 and the guide platform 2 respectively, the anti-slip ring 25 is fixedly sleeved on the guide rod 21, the pressure plate 3 is hingedly mounted on the base 1 through the hinge 6, the cylinder seat 52 is fixedly mounted on the base 1, the bottom of the linear telescopic cylinder 5 is hingedly mounted on the cylinder seat 52, a dovetail groove is provided on the bottom surface of the pressure plate 3, the slider 51 is slidably installed in the dovetail groove on the bottom surface of the pressure plate 3, the linear telescopic cylinder 5 is hinged to the slider 51, and a second pressure block is provided on the bottom surface of the pressure plate 3.
[0014] The base 1 is also fixedly mounted with a pad 4 for limiting the counterclockwise rotation angle of the pressing plate 3. After the pressing plate 3 is rotated to a horizontal state, it is restricted from further rotation.
[0015] A knob bolt 24 is threadedly installed on the guide platform 2. Tightening the knob bolt 24 to press on the guide rod 21 can limit its sliding. After the guide rod 21 is pulled outward, and when the first pressure block 23 presses and limits the support bracket, the guide rod 21 can be limited and fixed by tightening the knob bolt 24 to press it.
[0016] A vertical plate 31 is vertically fixedly installed on the pressure plate 3, and a first bolt 32 is screwed on the vertical plate 31. A screw sleeve 33 that matches the first bolt 32 is fixedly installed on the base 1. When the linear telescopic cylinder 5 works abnormally, the linear telescopic cylinder 5 can be removed for inspection and maintenance, and the first bolt 32 can be screwed into the screw sleeve 33 to limit and fix the pressure plate 3.
[0017] Pull the combination of the guide rod 21 and the first pressure block 23 outward to avoid interference between the support bracket and the first pressure block 23 when clamping and positioning. The pressure plate 3 is in a vertical state, and the L-shaped support bracket is placed in the positioning groove 11 on the top of the base 1. Under the action of the elastic force of the spring 22, the first pressure block 23 presses on the support bracket to limit its freedom in the front and rear directions. The piston rod of the linear telescopic cylinder 5 extends and retracts outward, and the slider 51 is driven by the piston rod to move, so that the pressure plate 3 rotates 90° counterclockwise around the hinge 6 to a horizontal state. The second pressure block of the pressure plate 3 presses on the support bracket, and cooperates with the bottom surface of the positioning groove 11 to limit the freedom of the support bracket in the up and down directions, and limits the freedom of the support bracket in the left and right directions through the left and right inner walls of the positioning groove 11.
