Description

Chuck type tool for laser marking

Technical Field

The utility model relates to laser marking, in particular to a chuck type tool for laser marking.

Background

Laser marking is to form a designed mark or pattern lamp by adjusting the point position of laser and leaving the mark point on the workpiece by the laser and connecting the mark points. When laser marking is performed on the outer surface of a cylindrical workpiece, such as a cup, a candlestick, or the like, the workpiece is generally clamped by a chuck type tool. Existing chuck-type tooling generally includes: the device comprises a device frame, a chuck rotating on the device frame and a drive for driving the chuck to rotate. The jaws of the chuck are abutted against the inner wall of the workpiece, so that the workpiece is fixed. According to the laser marking range, the outer wall of the workpiece is divided into a plurality of uniform parts, and the uniform parts are sequentially marked as a first area, a second area and a third area … …. Thus, the laser transmitter is matched with the two-axis moving module corresponding to the Y axis and the Z axis, the first area right in front is marked, and after the first area is marked, the chuck rotates by a corresponding angle, so that the second area is marked right in front of the laser transmitter.

Because the materials of the workpieces such as the cup and the candlestick are more involved: glass, plastic, ceramic, aluminum, and the like. In the process of chuck fixing, when the claw touches the inner wall of the workpiece to further tightly prop against the inner wall, the claw moves excessively, so that damage conditions such as fragmentation, deformation and the like are very easy to occur, and the workpiece is covered on the claw for fixing, so that the claw is blocked, and the position of the claw is inconvenient to see intuitively. If the clamping jaw is only enabled to initially touch the inner wall and is not further abutted, after the chuck rotates, the workpiece and the clamping jaw are easy to relatively deflect.

The current solution is: and a thicker soft layer which can be extruded and deformed is adhered to the outer wall of the clamping jaw, and the extrusion and deformation of the soft layer is matched with the clamping jaw which is slowly moved for a plurality of times, so that the chuck is fixed on a workpiece. However, in this way, the error in the coaxiality between the workpiece and the chuck is easily increased, so that the positioning of the workpiece is not accurate enough, and the pattern is also easily deviated.

The first port of the second air pipe 8 for air outlet is connected to the pneumatic chuck 6, and the second port of the air inlet is connected to the first port of the first air pipe 7 through a rotary joint 17. That is, the second air tube 8 is positioned in the suction cup mounting portion 5, and the second port is penetrated from the second shaft 12a and connected to the first port of the first air tube 7. The specific steps include: the mounting bracket 1 bottom fixedly connected with connection piece 15, fixedly connected with vacuum generator 16 on the connection piece 15, vacuum generator 16 is connected to the first port of first gas pipe 7, and the stiff end fixed connection of rotary joint 17 is in vacuum generator 16, and the second port of second gas pipe 8 is connected in the rotatory end of rotary joint 17, sets up the position of connection piece 15 and vacuum generator 16, makes the rotatory end of rotary joint 17 rotate round first axis too. The pneumatic suction cup 6 can work normally and also can rotate together with the first shaft 2.

Thus, for a cylindrical workpiece, the workpiece is placed on the chuck 3, and the claw 3a of the chuck 3 is adjusted to primarily touch the inner wall of the side edge of the workpiece, so that the workpiece is primarily positioned; the inner wall of the top of the workpiece is adsorbed by matching with the pneumatic chuck 6, so that the workpiece can be very stably fixed on the chuck type tool and can be very stably rotated along with the chuck 3.

Referring to fig. 3 and 6, alternatively, the mounting frame 1 includes: an upper part 1-1 and a lower part 1-2. The first shaft 2 and the first drive 4 are both connected to the upper part 1-1, and correspondingly, the chuck 3 is also connected to the upper part 1-1; the lower part 1-2 is detachably connected to the upper part 1-1, and the first air tube 7 and the suction cup mounting part 5 are connected to the lower part 1-2, respectively, and the pneumatic suction cup 6 and the second air tube 8 are also arranged in the lower part 1-2.

Therefore, after the connection between the upper part 1-1 and the lower part 1-2 is released, the chuck type tool can be conveniently divided into two parts, and the assembly, the repair and the maintenance are convenient.

Referring to fig. 5 and 6, the pneumatic chuck 6 can be optionally adjusted up and down. In this way, it is possible to adapt to workpieces of different heights.

The compression screw 19 is tightened to fix the movable portion 1-2-2 to these optical axes 18. The first air tube 7 and the suction cup mounting portion 5 are connected to the movable portion 1-2-2.

Thus, the pneumatic suction cup 6 can be adjusted up and down by loosening the pressing screw 19 and moving the movable portion 1-2-2 up and down.

Referring to fig. 3 and 4, in combination with the arrangement of "the air chuck 6 can adjust the position up and down", the chuck-type tool may further include: compressing the spring 20. The compression spring 20 is disposed between the pneumatic suction cup 6 and the suction cup mounting portion 5, so that the pneumatic suction cup 6 is in a trend away from the suction cup mounting portion 5. The specific steps include: the section of connecting pipe 6a on the pneumatic sucker 6 is in a step shape, the upper connecting section 6a-1 is larger in size and is in a regular hexagon, and the upper mounting block 13 is provided with a matched regular hexagon third through hole; the lower connecting section 6a-2 is smaller in size and is fixedly connected with a nut 21 through threads; the compression spring 20 is sleeved on the upper connecting section 6a-1, and two ends of the compression spring respectively prop against the pneumatic sucker 6 and the upper mounting block 13, so that the nut 21 props against the upper mounting block 13.

Because the pneumatic chuck 6 is in the workpiece after the workpiece is placed on the chuck 3, the workpiece is blocked, the position of the pneumatic chuck 6 cannot be directly observed, and the deformation amount of the pneumatic chuck 6 is limited, so that the adjustment of the upper and lower positions of the pneumatic chuck 6 is inconvenient. After the compression spring 20 is arranged, the pneumatic sucker 6 can overcome the downward movement of the compression spring 20, and the upper and lower positions of the pneumatic sucker 6 can be adjusted more conveniently under the condition that a workpiece is placed on the chuck 3. In addition, when the height change of the workpiece is small, the adjustment of the vertical position of the pneumatic chuck 6 can be performed by compressing the spring 20 without adjusting the vertical position.
