[0022] Figure 1 This is a schematic diagram of the overall operation of the present invention; Figure 2 This is a schematic diagram of the overall invention; Figure 3 This is a schematic diagram of the clamping cylinder assembly of the present invention; Figure 4This is a schematic diagram of the clamping cylinder assembly components of the present invention; Figure 5 This is a schematic diagram of the cylinder slider of the present invention; as shown in the figure, a cylindrical workpiece clamping device includes a base 2, a base plate 3 mounted on the base 2, a clamping cylinder assembly mounted on the base 2, and a clamping slider assembly mounted in conjunction with the base plate; the clamping cylinder assembly drives the clamping slider assembly to reciprocate along the length direction of the base plate to clamp or release the cylindrical workpiece 1; the cylindrical workpiece clamping device of this technical solution can achieve rapid clamping and positioning of the cylindrical workpiece through the clamping cylinder assembly set on the base 2, ensuring the stability of the cylindrical workpiece during processing, assembly or inspection. When the clamping cylinder assembly works in conjunction with the clamping slider assembly, the overall structure sliding clamping process is stable and reliable, and the workpiece positioning is accurate.

[0023] In this embodiment, the clamping slider assembly includes a clamping block 10, a guide slider 8, and a drive slider 12 fixedly connected to the clamping block 10. The clamping cylinder assembly drives the drive slider 12 and the clamping block 10 to slide back and forth. There are two clamping blocks 10 with identical structures. The clamping ends of the two clamping blocks 10 are arranged opposite each other. The drive slider 12 is driven by the clamping cylinder assembly. The sliding of the drive slider 12 drives the clamping blocks 10 to slide back and forth. The two clamping blocks 10 move closer or further away simultaneously to clamp or release the workpiece.

[0024] In this embodiment, a base plate slide rail 7 is installed on the base plate 3. The guide slider 8 is slidably installed in conjunction with the base plate slide rail 7, and the clamping block 10 is fixedly connected to the guide slider. A set of base plate slide rails 7 are arranged in parallel on the base plate 3. The guide slider 8 works in conjunction with the base plate slide rail 7, and the clamping block 10 is fixedly installed in conjunction with the guide slider 8. The combination of the guide slider 8 and the base plate slide rail 7 makes the overall structure more stable and reliable during operation, and the clamping and positioning more precise.

[0025] In this embodiment, the clamping block 10 has two ends that protrude outward to form clamping block wing plate portions 9 for mounting with the guide slider. The clamping block wing plate portions 9 are fixedly mounted to the upper end face of the guide slider 8. After the two ends of the clamping block 10 protrude to form the clamping block wing plate portion 9 structure, the clamping block wing plate portion 9 is attached to the upper end face of the guide slider 8 and locked by locking bolts. After the two ends of the clamping block 10 are stably installed, the parallel bottom plate slide rails 7 ensure that the clamping block maintains its positional stability during operation, thus ensuring stable and reliable clamping.

[0026] In this embodiment, the clamping block 10 is concave inward (i.e., as shown in the image). Figure 2The clamping surface of the clamping block 10 is formed by a recessed structure to accommodate the cylindrical workpiece. An elastic material 11 is provided on the surface of the clamping surface. The elastic material 11 (rubber or other suitable material, selected according to the clamping material) is adhered to the surface of the clamping block 10 to ensure clamping stability while providing a certain degree of elasticity to the clamped workpiece, preventing damage from hard contact.

[0027] In this embodiment, there are two base plate slide rails 7 arranged parallel to each other on the base plate. The two clamping block wing plates 9 are respectively installed in conjunction with the two slide rails. The two clamping block wing plates 9 are respectively installed in conjunction with the two guide sliders 8 and the two base plate slide rails 7, ensuring stable and reliable clamping and preventing displacement during operation.

[0028] In this embodiment, the clamping cylinder assembly includes a drive cylinder 13 mounted on the base 2 and a cylinder slider 14 used in conjunction with the drive cylinder 13. The upper end of the cylinder slider 14 is fixedly mounted to the drive slider 12, and the reciprocating motion of the cylinder slider 14 drives the reciprocating motion of the drive slider 12. The drive cylinder 13 and the cylinder slider 14 can adopt existing parallel opening and closing cylinders or other cylinder slider structures. The drive cylinder 13 drives the cylinder slider 14 to slide back and forth, thereby realizing the reciprocating motion of the drive slider 12.

[0029] In this embodiment, the cylinder sliders 14 consist of two identical cylinder sliders 14 arranged in the same horizontal direction. The driving cylinder 13 drives the two cylinder sliders 14 to move closer or further away simultaneously. A strip-shaped guide groove 15 is provided on the upper surface of the driving cylinder 13, and a slider guide arm 16 extends from the end of the corresponding cylinder slider 14. The slider guide arm 16 slides within the strip-shaped guide groove 15, ensuring stable and reliable sliding. (The lower end faces of the two cylinder sliders 14 are fitted with the two slider guide arms 16 to ensure that the two cylinder sliders 14 do not experience interference during operation. The gap and height difference between the workpieces are set accordingly based on actual use.)

[0030] In this embodiment, a guide copper sleeve 4 for positioning and installation is provided on the base plate 2, and a handle 5 is installed on the base plate 2. The guide copper sleeve 4 is used with the installation station for quick positioning and installation, and is used with the quick locking device 6 (an existing locking device can be used, which will not be described in detail here) for quick locking, saving installation time.
