Description
Technical Field
The utility model relates to a connecting device between pneumatic cylinder and the heavy load of driven, tenon fourth of the twelve earthly branches formula connecting device between two connecting pieces in pneumatic cylinder drive heavy load specifically says so.
Background
The equipment for driving heavy load by hydraulic cylinder, such as a hydraulic shearing machine, is characterized by that the piston rod of hydraulic cylinder can be used for driving heavy load shearing knife to make up-and-down reciprocating movement by means of two connecting pieces to implement cutting steel plate, i.e. the piston rod, piston rod side connecting piece, load side connecting piece and load are connected in turn, in which the piston rod side connecting piece is a transition shaft, and the load side connecting piece has several kinds of levers or connecting rods, etc.. The connection pair between the two connecting pieces mostly uses a bolt connection pair, namely, the transition shaft is in a blind hole nut shape, and the connection end (the connection end between the load side connecting piece and the transition shaft) is in a screw rod shape. The bolt connection pair has the defects that the hydraulic cylinder of the hydraulic shearing machine drives large load and high vibration, and the bolt connection pair can be twisted and loosened under the vibration with high strength and long time, so that the reliability of equipment is influenced.
Disclosure of Invention
In order to solve the technical problem, the utility model aims at providing a mortise and tenon joint formula connecting device between two connecting pieces in the heavy load of pneumatic cylinder drive.
The purpose of the utility model is realized like this: it includes piston rod side connecting piece and load side connecting piece, and piston rod side connecting piece is transition axle, characterized by: the transition shaft is in tenon-and-mortise connection with the load side connecting piece, specifically, the transition shaft is in a boss shape, a convex column of the upper half part of the boss is a blind hole nut type tenon shoulder, and the lower half part of the boss is a tenon; the connecting end of the load side connecting piece is in a mortise shape, the mortise is formed by enclosing a left half body and a right half body which are symmetrical, a mortise shoulder hole is formed in the mortise and is in a circle runway shape, a tenon is arranged in the mortise and extends out of the mortise shoulder hole, the tenon shoulder and the mortise shoulder hole are matched, the mortise further comprises a mortise positioning plate, a circle of positioning plate flange bolt holes are formed in the mortise positioning plate, a circle of mortise flange bolt holes are formed in the upper surface of the mortise wall and are downward opened, the mortise is arranged on the mortise positioning plate, the mortise flange bolt holes are in one-to-one correspondence with the circle of positioning plate flange bolt holes, and the flange bolts are screwed into each pair of corresponding flange bolt holes to fix the mortise on the mortise positioning plate.
The assembling mode is that the blind hole nut type tenon shoulder of the boss-shaped transition shaft is screwed into the piston rod lead screw section, then the two half-mortise parts are placed on the mortise positioning plate, the tenon is arranged in the mortise from left to right to the tenon integration, each flange bolt is screwed in, and the mortise is fixed on the mortise positioning plate, so that the mortise and tenon connection is realized. The piston rod moves up and down to drive the two connecting pieces connected by the tenon-and-mortise work to move up and down. Because the tenon shoulder holes and the tenon shoulders are matched in a circle of runway shape, the tenon-and-mortise joint cannot be twisted even if heavy load is driven and vibration is large.
Compared with the prior art, the utility model has the positive effects that: as the tenon and mortise are not twisted, the looseness prevention of all the connection pairs between the load and the hydraulic cylinder can be realized, and the reliability of the system operation is obviously improved.
Drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of the present invention.
Fig. 2 is an exploded view of the boss-shaped transition shaft and mortise, i.e., tenon-and-mortise structure of fig. 1.
Detailed Description
The hydraulic cylinder 1 is fixed on a platform 2 of a support 8, the lower end of the support is fixed on a foundation, a piston rod 3 penetrates through a hole of the platform and enters the support, and the piston rod of the hydraulic cylinder 1 comprises a piston rod screw rod section; the transition shaft serving as the piston rod side connecting piece is in mortise-tenon connection with the load side connecting piece, specifically, the transition shaft 5 is in a boss shape (in a convex shape by longitudinal section), a convex column at the upper half part of the boss is a blind hole nut type 53 tenon shoulder 51, the lower half part of the boss is a tongue 52, and the blind hole nut type tenon shoulder is screwed into a piston rod screw section; the connecting end of the load side connecting piece 7 is in a mortise shape 6, the mortise is formed by combining two symmetrical mortise half bodies 61 and 62, a mortise shoulder hole 64 is formed in the mortise, the mortise shoulder hole is in a circle track shape (formed by two straight lines and two circular arc lines), a tenon is arranged in the mortise, a tenon shoulder extends out of the mortise shoulder hole, the mortise is matched with the mortise shoulder hole, the mortise further comprises a mortise positioning plate 63, a circle of positioning plate flange bolt holes 65 are formed in the mortise positioning plate, a circle of mortise flange bolt holes 66 are formed in the upper surface of the mortise wall, the mortise is placed on the mortise positioning plate, a circle of mortise flange bolt holes corresponds to a circle of positioning plate flange bolt holes one by one, and the flange bolts 9 are screwed into each pair of corresponding flange bolt holes to fix the mortise on the mortise positioning plate.
The assembling mode is that the boss-shaped transition shaft is firstly installed on the piston rod, specifically, the locking nut 4 and the blind hole nut type tenon shoulder of the transition shaft are sequentially screwed into the screw rod section of the piston rod, the locking nut is screwed down on the boss-shaped transition shaft, and the boss-shaped transition shaft is locked to prevent the boss-shaped transition shaft from loosening; and then the two half mortise bodies are placed on a mortise positioning plate, the tenon is integrated from left to right, the tenon is arranged in the mortise, the flange bolt is screwed in, and the mortise is fixed on the mortise positioning plate, so that the mortise and tenon connection is realized. The piston moves up and down to drive the mortise and tenon joint, the load side connecting piece and the heavy load to move up and down in sequence. Because tenon shoulder hole and tenon shoulder are round runway shape cooperation, even the utility model discloses the heavy valve of drive, vibration are big, can not have torsional trend between the tenon fourth of the twelve earthly branches, and connecting device can not take place to twist reverse promptly.
