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.
