In order to solve the above problem, the utility model provides a following technical scheme: a split type heating cushion block for a welding machine comprises an upper rectangular block and a lower rectangular block, wherein the upper rectangular block is detachably arranged above the lower rectangular block; the middle area of the upper surface of the upper rectangular block is provided with a plurality of rows of vacuum holes, and each row of vacuum holes are uniformly arranged at intervals; a first air exhaust hole is formed in the middle area of the lower rectangular block, a sealing ring is arranged on one side, close to the upper rectangular block, of the first air exhaust hole, a cavity is formed in the area, opposite to the vacuum hole, of the lower surface of the upper rectangular block, the cavity is communicated with a second air exhaust hole, and the second air exhaust hole is matched with the first air exhaust hole and is connected with an external vacuum device; go up the rectangular block and be equipped with first screw hole all around, down the rectangular block all around with the corresponding department of first screw hole is equipped with the second screw hole, the screw with first screw hole with the second screw hole is connected, realizes going up rectangular block and rectangular block's dismantled connection down.

Preferably, the lower rectangular block has a length and a width of 62.82cm and 45cm, respectively.

Preferably, the minimum spacing of the vacuum holes is 2cm

Preferably, the rows of vacuum holes are different, and the number of rows is at least 2.

The utility model discloses compare in prior art's beneficial effect and lie in:

the heating cushion block is designed into an upper rectangular block structure and a lower rectangular block structure which are detachable, and a plurality of upper rectangular blocks with different numbers of vacuum holes are designed. During operation, according to frame products with different sizes, the frame products with different sizes can be fixed only by replacing the upper rectangular blocks, namely selecting the upper rectangular blocks with proper vacuum holes to be installed on the lower rectangular blocks. Therefore, the problems that heating cushion blocks with different sizes need to be processed, the quick heating cushion blocks need to be frequently disassembled and assembled and the like can be solved, the horizontal adjustment precision of the heating module is improved, the unevenness of the module in the vertical and horizontal directions is avoided, and the packaging quality is improved.

Detailed Description

The technical solution in the embodiments of the present invention is now described in detail. The described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention.

A split type heating cushion block for a welding machine comprises an upper rectangular block and a lower rectangular block, wherein the upper rectangular block is detachably arranged above the lower rectangular block; the middle area of the upper surface of the upper rectangular block is provided with a plurality of rows of vacuum holes, and each row of vacuum holes are uniformly arranged at intervals; a first air suction hole is formed in the middle area of the lower rectangular block, a sealing ring is arranged on one side, close to the upper rectangular block, of the first air suction hole, a cavity is formed in the area, opposite to the vacuum hole, of the lower surface of the upper rectangular block, the cavity is communicated with a second air suction hole, and the second air suction hole is matched with the first air suction hole and is connected with an external vacuum device; go up the rectangular block and be equipped with first screw hole all around, down the rectangular block all around with the corresponding department of first screw hole is equipped with the second screw hole, the screw with first screw hole with the second screw hole is connected, realizes going up rectangular block and rectangular block's dismantled connection down.

The upper rectangular block is generally designed with a plurality of blocks, and the upper surface of each upper rectangular block is provided with a different number of the vacuum holes. Preferably, the rows of vacuum holes are different in number, and the number of rows is at least 2. For example, 2 rows of the vacuum holes are formed in the middle area of the upper surface of the upper rectangular block No. 1, 4 rows of the vacuum holes are formed in the middle area of the upper surface of the upper rectangular block No. 2, and 6 rows of the vacuum holes are formed in the middle area of the upper surface of the upper rectangular block No. 3.
