[0010] Furthermore, the L-shaped rib plate is provided with reinforcing ribs at the corners, and the provision of the reinforcing ribs improves the strength of the L-shaped rib plate.

[0011] Furthermore, the support platform assembly includes a second cylinder horizontally fixed to the second column by bolts, a support plate is fixed to the telescopic end of the second cylinder, and the second column is fixed to the table of the marking machine. The second cylinder is arranged to facilitate the removal of the support plate when clamping or disassembling the cylindrical workpiece, thereby increasing the operating space.

[0012] Furthermore, one end of the V-block is fixedly connected to the third column, and the first column, the second column and the third column are provided with a plurality of threaded holes in the vertical direction for adjusting the height of the first cylinder, the second cylinder and the V-block. The provision of a plurality of vertical threaded holes facilitates the adjustment of the height of the first cylinder, the second cylinder and the V-block according to the height of the marking head of different marking machines.

[0013] Furthermore, the second column and the third column are located on the same straight line, the first column is located on one side of the line connecting the second column and the third column, and the first column is close to the fixed column of the marking machine. The first column is set at the fixed column of the marking machine to prevent the first column from interfering with the operator's manual or mechanical arm installation or removal of the cylindrical workpiece.

[0014] Furthermore, an anti-skid layer is provided on the pressure head, and the provision of the anti-skid layer prevents the cylindrical workpiece from rotating in the opening of the V-shaped block.

[0015] The utility model discloses a clamping and fixing device for a marking machine, which has the following beneficial effects:

[0016] The utility model can fix the cylindrical workpiece by means of the V-block and the clamping assembly, and the horizontal movement arrangement of the supporting platform assembly facilitates exposure of the bottom end of the cylindrical workpiece, thereby increasing the operating space and making it easier for the robot arm to install or disassemble the cylindrical workpiece on the V-block.

[0020] The specific implementation methods of the utility model are described below to facilitate technical personnel in this technical field to understand the utility model, but it should be clear that the utility model is not limited to the scope of the specific implementation methods. For ordinary technical personnel in this technical field, as long as various changes are within the spirit and scope of the utility model defined and determined by the attached claims, these changes are obvious, and all utility model creations using the concept of the utility model are protected.

[0022] In this embodiment, the V-block 6 can be set to position the cylindrical workpiece 5 of different diameters in the radial direction. The pressing assembly 1 presses the cylindrical workpiece 5 from the opening direction of the V-block 6 to limit the radial direction of the cylindrical workpiece 5. The support platform assembly 2 can support and limit the bottom end of the cylindrical workpiece 5, and the horizontal movement of the support platform assembly 2 is convenient for exposing the bottom end of the cylindrical workpiece 5, increasing the operating space, and facilitating the external robot arm to automatically or the operator to manually install or remove the cylindrical workpiece 5 on the V-block 6. This makes it convenient for the marking machine to mark the end of the cylindrical workpiece 5.

[0023] Specifically, the pressing assembly 1 includes a first column 11 , a first cylinder 12 and a pressing head 13 .

[0024] The first column 11 is fixed on the table 8 of the marking machine, and an L-shaped rib plate 14 is bolted on one side of the first column 11, and the long side of the L-shaped rib plate 14 is threadedly connected with the fixed end of the first cylinder 12. The first air pipe is fixed by the L-shaped rib plate 14, so that the first cylinder 12 is suspended at the opening of the V-shaped block. Compared with directly fixing the first cylinder 12 on the first column 11, the L-shaped rib plate 14 increases the distance between the first cylinder 12 and the first column 11, thereby increasing the installation space.

[0025] The L-shaped rib plate 14 is provided with reinforcing ribs 141 at the corners. The provision of the reinforcing ribs 141 improves the strength of the L-shaped rib plate 14.

[0026] The first cylinder 12 is fixed on the first column 11, and a pressing head 13 for pressing the cylindrical workpiece 5 located in the opening of the V-block 6 is provided on the telescopic end of the first cylinder 12. The arrangement of the first cylinder 12 facilitates the movement of the pressing head 13 to press the cylindrical workpiece 5.

[0027] The pressure head 13 is provided with an anti-skid layer. The anti-skid layer prevents the cylindrical workpiece 5 from rotating in the opening of the V-shaped block 6. The pressure head 13 and the V-shaped block 6 are located on the same horizontal straight line.

[0028] Specifically, the supporting platform assembly 2 includes a second column 21 , a second cylinder 22 and a supporting plate 23 .

[0029] The second column 21 is fixed on the table 8 of the marking machine, the second cylinder 22 is horizontally fixed on the second column 21 by bolts, and a support plate 23 is fixed on the telescopic end of the second cylinder 22. The arrangement of the second cylinder 22 facilitates the removal of the support plate 23 when the cylindrical workpiece 5 is clamped or disassembled, thereby increasing the operating space.

[0030] Preferably, but not limited to, the first cylinder 12 and the second cylinder 22 are both connected to an external pneumatic circuit controlled by a PLC, so that the extension and retraction of the first cylinder 12 and the second cylinder 22 can be easily controlled by the PLC.

[0031] As a further solution of this embodiment, one end of the V-block 6 is fixedly connected to the third column 7, and the third column 7 is fixed on the table 8 of the marking machine; and the first column 11, the second column 21 and the third column 7 are provided with a plurality of threaded holes in the vertical direction for adjusting the height of the first cylinder 12, the second cylinder 22 and the V-block 6. The provision of a plurality of vertical threaded holes facilitates the adjustment of the height of the first cylinder 12, the second cylinder 22 and the V-block 6 according to the height of the marking head 3 of different marking machines.

[0032] As another solution of this embodiment, when clamping a flat workpiece, the V-shaped block 6 on the third column 7 can be replaced with a clamping plate.

[0033] Preferably, but not limited to, the second column 21 and the third column 7 are located on the same straight line, the first column 11 is located on one side of the line connecting the second column 21 and the third column 7, and the first column 11 is close to the fixed column 4 of the marking machine. The first column 11 is set at the fixed column 4 of the marking machine to prevent the first column 11 from hindering the operator from manually or the external robot arm from automatically installing or removing the cylindrical workpiece 5.

[0034] This embodiment takes the cylindrical workpiece 5 as an example to illustrate the working process of this solution:

[0035] The operator places the stud into the opening of the V-block 6 by an external robotic arm or manually, extends the pressure head 13 by the first cylinder 12 to press the stud against the V-block 6, removes the arm or robotic arm, and extends the support plate 23 by the second cylinder 22 to support the bottom of the stud, completing the installation of the stud.

[0036] After the marking machine has finished marking the top of the stud, the second cylinder 22 is used to retract the support plate 23 to expose the bottom of the stud, the arm or the mechanical arm holds the bottom of the stud, and the first cylinder 12 is used to retract the pressure head 13 to release the stud, and finally the arm or the mechanical arm is used to take out the stud to complete the disassembly of the stud.

[0037] Although the specific implementation of the utility model is described in detail in conjunction with the drawings, it should not be understood as limiting the scope of protection of this patent. Within the scope described in the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
