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. 1-2, the present invention provides the following technical solutions: the utility model provides an accurate servo electric jar of pay-off, includes main part 1, and main part 1 sets up to the cavity form, and 1 inside propelling movement subassembly 2 and the buffering subassembly 3 that are provided with of main part, propelling movement subassembly 2 and buffering subassembly 3 set up respectively in 1 inside both ends of main part.

Referring to fig. 2-3, the pushing assembly 2 includes a screw rod 22, a piston 21 is slidably mounted inside the main body 1, a threaded hole 211 is formed in a center of the piston 21, the screw rod 22 is inserted into the threaded hole 211, a connecting rod 23 is mounted on an end surface of the piston 21, one end of the connecting rod 23, which is away from the piston 21, is inserted outside one end of the main body 1, a push plate 24 is mounted at one end of the connecting rod 23, which is away from the piston 21, a sliding groove 213 is formed in an inner wall of the main body 1, a sliding block 212 is mounted on a side surface of the piston 21, and the sliding block 212 is clamped inside the sliding groove 213.

The buffer assembly 3 comprises a pressure plate 31, the pressure plate 31 is arranged on one side of the piston 21 far away from the connecting rod 23, a support rod 32 is arranged on the end surface of the pressure plate 31 far away from the piston 21, a buffer cylinder 33 is arranged at one end of the support rod 32 far away from the pressure plate 31, a sliding plate 34 is arranged inside the buffer cylinder 33 in a sliding mode, and one end of the support rod 32 far away from the pressure plate 31 is arranged on the end surface of the sliding plate 34 close to the pressure plate 31.

The working principle is as follows: when the device is started, under the drive of external torque, the screw rod 22 starts to rotate to penetrate through the threaded hole 211 of the piston 21, and the piston 21 is clamped inside the sliding groove 213 of the main body 1, when the screw rod 22 rotates, the threaded hole 211 and the threaded meshing relation exists between the screw rod and the threaded hole, and the piston 21 is limited by the clamping of the slide block 212 and the threaded hole, so that the piston 21 cannot rotate, the piston 21 can realize vertical movement due to the rotation of the screw rod 22, the piston 22 can drive the push plate 24 to realize vertical movement through the connecting rod 23, when the piston 21 moves downwards, the push plate 24 is in a material pushing state, so that the movement speed of the piston 21 is relatively slow, when the piston 21 moves upwards, the piston is in a resetting device, the movement speed is fast due to the non-load matching state, and along with the upwards movement, the press plate 31 is pushed upwards, the press plate 31 drives the sliding plate 34 to move in the buffer cylinder 33 through the support rod 32, because the gas quantity in the buffer cylinder 33 is constant, the pressure in the buffer cylinder 33 changes when the sliding plate 34 moves, and the pressure in the buffer cylinder 33 changes to buffer the force of the sliding plate 34, so that the upward speed of the piston 21 is buffered, the quick collision between the piston 21 and some parts in the main body 1 is avoided, and the buffer protection of the device is realized.
