Description

Technical Field

[0001] The utility model relates to the technical field of mahjong milling machines, in particular to a mahjong clamping mechanism for mahjong milling machines. Background Art

[0002] The shape, size, text or pattern of mahjong tiles need to be realized through molds. The molten plastic is injected into the mold and forms the initial shape of the mahjong tile after cooling. After the mahjong tile is taken out of the mold, it needs to be trimmed and polished to remove burrs and uneven parts.

[0003] In the existing technology, when milling mahjong tiles, a positioning device is generally used to clamp the tiles, and then the milling device is used to mill the outer surface of the tiles. However, this still has the following disadvantages: when loading the tiles, the tiles are manually placed inside the positioning device, the processed tiles are removed, and the unprocessed tiles are placed. This increases the risk of hand injuries to workers and makes mahjong processing more dangerous. To address this problem, we have proposed a mahjong clamping mechanism for a mahjong milling machine to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to provide a mahjong clamping mechanism for a mahjong milling machine to solve the problems raised in the above background technology.

[0006] The positioning portion includes a U-shaped bracket, a second hydraulic rod, a mounting slide and an L-shaped plate, wherein the right end surface of the second hydraulic rod is fixedly connected to the left end surface of the U-shaped bracket, the bottom surface of the U-shaped bracket is fixedly connected to the top surface of the processing table, the mounting slide is fixedly sleeved on the outer surface of the output shaft of the second hydraulic rod, and the right end surface of the L-shaped plate is fixedly connected to the left end surface of the mounting slide;

[0007] A clamping portion is provided above the processing table;

[0008] The clamping part includes a pneumatic slider, a mounting plate, a pneumatic slide rail and a support block. The pneumatic slider is slidably sleeved on the outer surface of the pneumatic slide rail. The bottom surface of the mounting plate is fixedly connected to the top surface of the pneumatic slider. A groove is provided on the left end surface of the pneumatic slider. A receiving groove is provided on the inner wall of the groove. The support block is arranged inside the groove. The outer surface of the support block extends into the inside of the receiving groove and is slidably connected to the inner wall of the receiving groove.

[0009] A further improvement is that the positioning part also includes a rotating block, a rotating base and a protective shell. The top surface of the rotating block is rotatably connected to the bottom surface of the L-shaped plate through a bearing seat, and the bottom surface of the rotating base is fixedly connected to the top surface of the processing table. By setting a rotating base, a second hydraulic rod and a rotating block, the extension of the second hydraulic rod is controlled to enable the rotating block and the rotating base to squeeze and position the mahjong blocks.

[0010] A further improvement is that the protective shell is arranged on the left side of the rotating base, and the bottom surface of the protective shell is fixedly connected to the top surface of the processing table. By setting the protective shell, the flying chips during the milling process are prevented.

[0011] A further improvement is that the clamping part also includes a column, a first hydraulic rod, a clamping plate and a spring, the bottom surface of the column is fixedly connected to the top surface of the processing table, and the top surface of the column is fixedly connected to the bottom surface of the pneumatic slide rail. By arranging the pneumatic slide rail and the pneumatic slider, the mahjong blocks can be easily transported.

[0012] A further improvement is that the bottom surface of the first hydraulic rod is fixedly connected to the top surface of the mounting plate, and the clamping plate is fixedly sleeved on the outer surface of the output shaft of the first hydraulic rod. By setting the first hydraulic rod and the clamping plate, the extension of the first hydraulic rod is controlled so that the clamping plate clamps the mahjong blocks, so that the mahjong blocks remain stable when moving. When moved to the far left, the processed mahjong blocks are pushed down to the left from the rotating base.

[0013] A further improvement is that one end of the spring is fixedly connected to the outer surface of the support block, and the other end of the spring is fixedly connected to the inner wall of the mounting plate. By arranging the spring and the support block, when the feeding device pushes the mahjong block onto the support block, the support block is used to support the mahjong block, which makes it easier for the splint to clamp the mahjong block. When the mounting plate moves to the left, the rotating base pushes the support block to move, and the support block moves to the inside of the groove, so that the mahjong block can be placed on the top surface of the rotating base.

[0014] A further improvement is that the top surface of the support block is on the same horizontal plane as the top surface of the rotating base, the front and rear width of the inner wall of the groove is greater than the front and rear width of the top of the rotating base, and a protective shell is provided to prevent processing debris from splashing.
