Detailed Description

Example 1
In the embodiment, when the azimuth description is performed, the direction shown in fig. 1 is taken as the front in the description, the direction opposite to the direction shown in fig. 1 is taken as the rear in the description, and the up-down and left-right directions in fig. 1 are still up-down and left-right directions in the description.
Referring to fig. 1 to 10, the full-stroke heavy-duty laser pipe cutting clamping disc of the embodiment mainly comprises clamping jaws 1, a front cover 2, a rear cover 3, an air cylinder 4, a transmission mechanism 5, a synchronous mechanism 6, a displacement detection mechanism 7, a frame 8 and a rotary driving mechanism 9.
The clamping jaw 1 is used for clamping a workpiece during operation of the chuck of the present embodiment.

The clamping jaw 1 comprises two clamping jaws which are arranged up and down and two clamping jaws which are arranged left and right; the jaw 1 is of prior art and its construction is not described in detail.
The front cover 2 is a disc-shaped structural member, and a circular or square clamping hole for passing a clamped workpiece during use is formed in the middle of the front cover 2, and the clamping hole in the embodiment is preferably a square hole. Two sliding grooves are respectively arranged on the front cover 2 in the transverse direction and the longitudinal direction; the inner ends of the four sliding grooves are communicated with the clamping piece holes.
The rear cover 3 is a disc-shaped structural member, a clamping hole which is penetrated in the front-back direction and corresponds to the clamping hole of the front cover 2 is arranged in the middle of the rear cover 3, and the clamping holes of the front cover 2 and the rear cover 3 jointly form a workpiece accommodating hole 100 of the chuck of the embodiment.
The air cylinders 4 are used as power sources for the movement of the clamping jaws 1, the four air cylinders 4 correspond to the four clamping jaws 1, the four air cylinders 4 are of the same structure, and each air cylinder 4 corresponds to the power source for one clamping jaw 1. Unlike the existing pneumatic chuck of the same type, which is used as a cylinder structure of a power source, the cylinder 4 of the embodiment is a stroke-adjustable cylinder with a stroke adjusting mechanism, so that the cylinder used as the power source can accurately control the movement position (namely the clamping position during working) of the clamping jaw 1 used as an execution terminal, and the clamping jaw 1 is prevented from being clamped and the deep groove function of the surface of a workpiece is crossed.
Referring to fig. 4, as a specific implementation, the cylinder 4 is mainly composed of a cylinder body 41, a cylinder head 42, a piston 43, a piston rod 44, and a stroke adjustment mechanism 45. The cylinder 41 is a hollow tubular structural member with two open ends; the cylinder cover 42 comprises a first cylinder cover 42-1 and a second cylinder cover 42-2, and the first cylinder cover 42-1 and the second cylinder cover 42-2 are respectively and fixedly connected with one open end of the cylinder body 41 in an airtight manner; the piston 43 is arranged in the cylinder 41 in a movable airtight manner and divides the space in the cylinder 41 into two air chambers, and an installation abdication counter bore is arranged in the middle of one side of the piston 43; unlike the solid piston rod of the cylinder commonly used in the existing pneumatic chucks of the same type, the piston rod 44 of the embodiment is a rod body with an inner end opening, an outer end being closed and a counter bore being axially arranged from the open end, the inner end of the piston rod 44 is integrally or fixedly connected with the piston 43, the inner end opening of the piston rod 44 is communicated with the mounting yielding counter bore of the piston 43, and the outer end of the piston rod 44 is in airtight movable extension outwards from the middle of the cylinder cover 42.
The stroke adjusting mechanism 45 mainly comprises an adjusting screw 45-1, an adjusting nut 45-2, a sealing element 45-3, a first check ring 45-4, a second check ring 45-5 and a gland 45-6, wherein the adjusting screw 45-1 is provided with a rod body and a screw head, the rod body of the adjusting screw 45-1 passes through the first cylinder cover 42-1 of the cylinder 4 and the gland 45-6 in an airtight manner through the sealing element 45-3 and then stretches into a counter bore of the piston rod 44, and the screw head of the adjusting screw 45-1 is arranged at the outer side of the first cylinder cover 42-1 of the cylinder 4; the adjusting nut 45-2 is arranged in the counter bore of the piston rod 44 and is in threaded fit connection with the adjusting screw 45-1, and is arranged on the rod body of the adjusting screw 45-1 in a linear motion but in a non-rotatable manner. The first check ring 45-4 is fixedly arranged on the inner side surface of the first cylinder cover 42-1 of the cylinder 4 and positioned on the periphery of the rod body of the adjusting screw 45-1, and the first check ring 45-4 is used for preventing the adjusting screw 45-1 from moving to the outer side of the closed end of the cylinder body 41 of the cylinder 4 when in use; the second check ring 45-5 is fixedly arranged on the end of the rod body of the adjusting screw 45-1 extending into the counter bore of the piston rod 44, and the second check ring 45-5 is used for preventing the adjusting nut 45-2 from falling off from the adjusting screw 45-1 in the process of stroke adjusting operation and use; the gland 45-6 is fixedly arranged in the mounting yielding counterbore of the piston 43 and is connected with the inner end of the piston rod 44.
The method of adjusting the stroke of the piston rod 44 of the cylinder 4 by the stroke adjustment mechanism 45 is: by rotating the adjusting screw 45-1 by the screw head of the adjusting screw 45-1, the adjusting nut 45-2 moves linearly on the adjusting screw 45-1 in the counter bore of the piston rod 44 with respect to the adjusting screw 45-1, and the adjusting nut 45-2 is moved to a corresponding position on the adjusting screw 45-1 according to the requirement of the maximum extension length of the piston rod 44 (i.e., the maximum stroke of the piston rod 44). When the piston rod 44 is in outward extending movement, when the gland 45-6 fixed on the piston 43 is in contact with the adjusting nut 45-2, the movement of the piston 43 is blocked by the adjusting nut 45-2, the piston rod 44 correspondingly stops extending outwards to reach a set stroke, and then the corresponding clamping jaw 1 is enabled to move to a set clamping position, so that the clamping-flattening prevention function of preventing the clamping jaw 1 from flattening a workpiece and the function of preventing the clamping jaw 1 from crossing a deep groove on the surface of a profile are realized.

When the air cylinder 4 is in operation, the cylinder 41 moves by the sliding of the four sliding blocks 46-3 on the two guide rails 46-2 due to the fact that the extending end of the piston rod 44 is fixed.
