Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a pneumatic fast loading and unloading anchor clamps, including fixed plate 10, die clamping cylinder 20 and grip block 30, die clamping cylinder 20 fixed mounting is in the center department on fixed plate 10 surface, die clamping cylinder 20 output end fixed mounting runs through the piston rod 21 of fixed plate 10, the bilateral symmetry fixed mounting of fixed plate 10 lower surface has guide bar 40, guide bar 40 outside slip has cup jointed grip block 30, second limiting plate 41 is installed to guide bar 40 tip screw thread, the one end that die clamping cylinder 20 was kept away from to piston rod 21 runs through grip block 30, first limiting plate 22 is installed to piston rod 21 tip screw thread.

Wherein the assembling and disassembling jig is used in a vertical state, ensures that the clamping plate 30 is positioned below the fixing plate 10, before clamping the workpiece, the clamping plate 30 slides down along the guide bar 40 due to gravity, and supports the clamping plate 30 by the first and second

limiting plates

22 and 41, thereby unfolding the clamping plate 30 and the fixing plate 10, then the workpiece to be clamped is placed between the clamping plate 30 and the fixing plate 10, then the clamping cylinder 20 drives the piston rod 21 to retract, and simultaneously drives the clamping plate 30 to move towards the side close to the fixing plate 10, and then the clamping plate 30 moves upward along the guide bars 40, thereby reducing the distance between the clamping plate 30 and the fixed plate 10, then the workpiece is clamped and fixed through the clamping plate 30 and the fixing plate 10, so that the workpiece can be quickly clamped, the stability of clamping the workpiece is improved, and the workpiece is prevented from falling off.

The center of the surface of the fixing plate 10 is provided with a first through hole 11 matched with the piston rod 21 in a penetrating way, the piston rod 21 penetrates through the first through hole 11, and the diameter size of the cross section of the piston rod 21 is smaller than the inner diameter size of the first through hole 11; thus, when the clamping cylinder 20 drives the piston rod 21 to retract, the fixed plate 10 does not block the movement of the piston rod 21.

A first threaded hole 23 is formed in the center of the end of the piston rod 21, a first screw 24 matched with the first threaded hole 23 is fixedly installed in the center of the upper surface of the first limiting plate 22 through a bolt, and the first limiting plate 22 is installed at the end of the piston rod 21 through the first screw 24 and the first threaded hole 23 in a matched threaded manner; a second threaded hole 42 is formed in the center of the end of the guide rod 40, a second screw 43 matched with the second threaded hole 42 is fixedly mounted in the center of the upper surface of the second limiting plate 41 through a bolt, and the second limiting plate 41 is mounted at the end of the guide rod 40 through the second screw 43 and the second threaded hole 42 in a matched threaded manner.

When the piston rod 21 is in the unfolded state, the clamping plate 30 slides downward along the guide rod 40, and then the clamping plate 30 is supported by the first limiting plate 22 and the second limiting plate 41, so that the clamping plate 30 is prevented from being separated from the guide rod 40 and the piston rod 21.

When the clamping cylinder 20 drives the piston rod 21 to retract, the piston rod 21 can drive the clamping plate 30 to move upwards through the first limiting plate 22, so that the distance between the clamping plate 30 and the fixing plate 10 is reduced, and then the workpiece is clamped and fixed through the clamping plate 30 and the fixing plate 10.

Wherein, in the use process of the clamping plate 30, the clamping plate 30 is easily damaged by extrusion, then the first limit plate 22 is detached from the end of the piston rod 21, the second limit plate 41 is detached from the end of the guide rod 40, then the clamping plate 30 can be detached from the piston rod 21 and the guide rod 40, a new clamping plate 30 is replaced, then the first limit plate 22 is installed at the end of the piston rod 21 in a threaded manner again, the second limit plate 41 is installed at the end of the guide rod 40 in a threaded manner, and the clamping plate 30 is supported by the first limit plate 22 and the second limit plate 41.

A second through hole 31 penetrates through the center of the surface of the clamping plate 30, the piston rod 21 penetrates through the second through hole 31, and the diameter size of the cross section of the piston rod 21 is smaller than the inner diameter size of the second through hole 31, so that the clamping plate 30 can be sleeved on the piston rod 21; the bilateral symmetry on grip block 30 surface runs through and has seted up third through-hole 32, and guide bar 40 runs through third through-hole 32, and the diameter size of guide bar 40 cross section is less than the internal diameter size of third through-hole 32, and grip block 30 can slide to cup joint on guide bar 40 like this, through the position of guide bar 40 restriction grip block 30, avoids grip block 30 to rotate round piston rod 21.

The working principle is as follows: when using, expand grip block 30 and fixed plate 10, then will treat the work piece of centre gripping and place between grip block 30 and fixed plate 10, then retract through die clamping cylinder 20 drive piston rod 21, drive grip block 30 simultaneously and move to the one side that is close to fixed plate 10, then grip block 30 upwards moves along guide bar 40, thereby reduce the distance between grip block 30 and the fixed plate 10, then fix the work piece centre gripping through grip block 30 and fixed plate 10, can realize the quick clamping of work piece, the stability of work piece centre gripping has been improved simultaneously, avoid the work piece to drop.
