Description

Cylinder support structure for overhead cylinders used in automobile body-in-white welding production lines

technical field

The utility model relates to a cylinder supporting structure, in particular to an overhead cylinder supporting structure used in a welding production line for automobile body-in-white.

Background technique

In the automobile body-in-white welding equipment, the tooling of each station on the automatic line is very important, bearing the weight of the workpiece itself and the force generated by welding. The sheet metal parts of the whole vehicle are heavy, and the support under it will be deformed due to long-term pressure, which will affect the welding accuracy. The flower pin cylinder for clamping the body-in-white is installed and fixed through the support. Not only is the position adjustment troublesome, but also the entire gravity is borne by the fixing bolts, so the safety and reliability are low.

Contents of the invention

The purpose of this utility model is to provide a support for the support of the support of the support of the support of the support of the support of the support of the support of the support of the support of the support of the production line of the automobile body-in-white, which is simple in structure, convenient to adjust the position of the support of the support of the support of the support of the support in all directions, the fixing bolts do not bear the gravity of the workpiece, and the degree of safety and reliability is improved. The structure overcomes the deficiencies of the prior art.

The supporting structure of the split pin cylinder used in the welding production line of automobile body-in-white of the utility model includes a support, a split pin cylinder, and positioning pins are arranged on the split pin cylinder, and there are long grooves on the positioning pins, and there are Flowering pressure claw; the top surface of the support is fixedly connected with one side of the first corner block by bolts, and a first gasket set is arranged between the first corner block and the top surface of the support; the other side of the first corner block There is a groove-shaped notch, one side of the second corner block is located in the notch and is fixedly connected with the first corner block by bolts, and a second gasket group is arranged between the first corner block and the second corner block; the second The other side of the corner block has a groove-shaped notch, a part of the connection block is located in the notch and is fixedly connected with the second corner block by bolts, and a third gasket group is arranged between the second corner block and the connection block; The above-mentioned overhead pin cylinder is fixedly connected with the other part of the connecting block by bolts.

The utility model is used for the support structure of the flower pin cylinder on the automobile body-in-white welding production line. , It is very convenient to adjust the position in the Z-axis direction and easy to operate; because the corner blocks are installed through the joints and fixed by bolts, the force borne by the cylinder can be transmitted to the joints of the corner blocks during operation, so that the fixing bolts do not Re-stressing improves the safety performance of the supporting structure.

Description of drawings

Fig. 1 is the structural representation of the specific embodiment of the utility model;

FIG. 2 is a schematic cross-sectional view of the first corner block shown in FIG. 1 .

Detailed ways

As shown in Figures 1 and 2: 1 is a support, and the bottom of the support 1 is fixedly connected to the tooling foundation on the automobile body-in-white welding production line by bolts. 8 is the blooming pin cylinder that is used for clamping the body-in-white on the production line, is provided with positioning pin 6 above the cylinder, has elongated groove on positioning pin 6, and blooming pressure claw 7 is arranged in the positioning pin 6. When the cylinder moves, the flowering pressure claw 7 turns over from the long groove to the outside, so as to achieve the purpose of clamping the workpiece. The above is the prior art and will not be described in detail.

2 is the first corner piece of L shape, and one side is processed with groove-shaped notch 12 and four connecting holes 13, and the other side is processed with four fixing holes 11. The top surface of the support 1 is fixedly connected to one side of the first corner block 2 through bolts and fixing holes, and a first gasket set 10 is provided between the first corner block 2 and the top surface of the support 1 .

One side of the second corner block 5 is located in the groove-shaped notch 12 of the first corner block 2 and fixedly connected with the connecting holes 13 by four bolts. A second gasket set 9 is provided between the first corner block 2 and the second corner block 5 .

The other side of the second corner block 5 has a groove-shaped notch, and a part of the connecting block 4 is located in the notch and is fixedly connected with the second corner block 5 by bolts. Between the second corner block 5 and the connecting block 4, a Third gasket set 3.

The flower pin cylinder 8 is fixedly connected with the other part of the connection block 4 by bolts.

Each gasket group is made up of a plurality of sheet metals of different thicknesses, so that increase or decrease, reach the position of adjusting three directions on the space of overhead cylinder 8.

After installation, the position of the flower pin cylinder 8 up and down, left and right, and front and rear can be adjusted through the thickness of each gasket group, that is, it is very convenient to adjust the position in the X-axis, Y-axis, and Z-axis directions, and it is easy to operate; Installed through the stop and fixed by bolts, the force borne by the cylinder can be transmitted to the stop of each corner block during operation, so that the fixing bolts are no longer stressed, and the safety performance of the supporting structure is improved.
