Description
Technical Field
The invention relates to a connecting device between a hydraulic cylinder and a driven heavy load, in particular to a mortise-tenon type connecting device between two connecting pieces in the process of driving the heavy load by the hydraulic cylinder.
Background
The hydraulic cylinder drives the heavy load shearing knife to reciprocate up and down via two connecting parts to cut off the steel plate, i.e. the piston rod, the piston rod side connecting part, the load side connecting part and the load are connected successively, with the piston rod side connecting part being the transition shaft and the load side connecting part including levers, connecting rods, etc. The connecting pair between the two connecting pieces mostly uses a bolt connecting pair, namely, the transition shaft is in a blind nut shape, and the connecting end (the connecting end with the transition shaft) of the load side connecting piece is in a screw rod shape. The adoption of the bolt connection pair has the defects that the hydraulic cylinder of the hydraulic shearing machine drives a large load and vibrates in a high-vibration mode, the bolt connection pair can twist under the vibration of high strength and long time, looseness is generated, and the reliability of equipment is affected.
Disclosure of Invention
In order to solve the technical problems, the invention aims to provide a mortise and tenon type connecting device between two connecting pieces in a heavy load driven by a hydraulic cylinder.
The purpose of the invention is realized in the following way: it includes piston rod side connecting piece and load side connecting piece, and piston rod side connecting piece is the transition axle, characterized by: the transition shaft is connected with the load side connecting piece in a mortise-tenon mode, specifically, the transition shaft is in a boss shape, a convex column at the upper half part of the boss is a blind hole nut type tenon, and the lower half part of the boss is a tongue; the connecting end of the load side connecting piece is in a mortise shape, the mortise is formed by combining left and right symmetrical mortise half bodies, a mortise hole is formed in the mortise, the mortise hole is in a ring of runway shape, a tongue is arranged in the mortise, the mortise extends out of the mortise hole, the mortise is matched with the mortise hole, the mortise further comprises a mortise positioning disc, a ring of flange bolt holes are formed in the mortise positioning disc, a ring of mortise flange bolt holes are formed in the upper surface of the mortise wall downwards, the mortise is placed on the mortise positioning disc, the ring of mortise flange bolt holes are in one-to-one correspondence with the ring of 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 disc.
The assembly mode is that the blind hole nut type tenon of the boss-shaped transition shaft is screwed into the screw rod section of the piston rod, then the two mortise halves are placed on the mortise positioning disc, the tenon is assembled from left to right, the tenon is installed into the mortise, each flange bolt is screwed in, the mortise is fixed on the mortise positioning disc, and mortise-tenon connection is achieved. The piston rod moves up and down to drive the two connecting pieces connected by the mortise and tenon to move up and down. Because the mortise hole and the mortise are in racetrack-shaped fit, torsion can not be generated between mortise and tenon even if heavy load is driven and vibration is large.
Compared with the prior art, the invention has the following positive effects: because torsion can not occur between mortise and tenon joints, all connection pairs between a load and a hydraulic cylinder can be prevented from loosening, and the running reliability of the system is obviously improved.
Drawings
The invention is further described below with reference to the 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., mortise and tenon, structure of fig. 1.
Detailed Description
The hydraulic cylinder 1 is fixed on a platform 2 of a bracket 8, the lower end of the bracket is fixed on a foundation, a piston rod 3 penetrates through a hole of the platform to enter the bracket, and the piston rod of the hydraulic cylinder 1 comprises a piston rod screw 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 (a longitudinal section is in a convex shape), a convex column at the upper half part of the boss is a blind hole nut type 53 tenon 51, the lower half part of the boss is a tongue 52, and the blind hole nut type tenon 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 left and right symmetrical mortise half bodies 61 and 62, a mortise hole 64 is formed in the mortise, the mortise hole is in a track shape (formed by two straight lines and two circular arc lines), a tongue is arranged in the mortise, the tongue extends out of the mortise hole, the tongue and the mortise hole are matched, the mortise further comprises a mortise positioning disc 63, a circle of positioning disc flange bolt holes 65 are formed in the mortise positioning disc, a circle of mortise flange bolt holes 66 are formed in the upper surface of the mortise wall downwards, the mortise is placed in the mortise positioning disc, the mortise flange bolt holes of the circle correspond to the positioning disc flange bolt holes of the circle one by one, and the flange bolts 9 are screwed into the corresponding flange bolt holes of each pair to fix the mortise on the mortise positioning disc.
The assembling mode is that the boss-shaped transition shaft is firstly arranged on the piston rod, specifically, the locking nut 4 and the blind hole nut type tenon of the transition shaft are screwed into the screw rod section of the piston rod in sequence, the locking nut is arranged on the boss-shaped transition shaft, the locking nut is screwed down, and the boss-shaped transition shaft is locked to prevent loosening; and then the two half mortise bodies are placed on the mortise positioning plate, the tongue is combined from left to right, so that the tongue is positioned in the mortise, the flange bolts are screwed in, the mortise is fixed on the mortise positioning plate, and mortise and tenon connection is realized. And the upper and lower movements drive the mortise and tenon joint, the load side connecting piece and the heavy load to move up and down in sequence. Because the tenon hole and the tenon are in racetrack-shaped fit, even if the heavy valve is driven by the invention and the vibration is large, the tenon-mortise joint has no torsion trend, i.e. the connecting device cannot twist.
