Abstract
The utility model discloses a piston mechanism with a cross-shaped sleeve structure and relates to the technical field of agricultural machines. The piston mechanism comprises a crankshaft (1), a connecting rod welding-on part (2), a piston welding-on part (6), a cross-shaped sleeve (4), a connecting rod hinge pin (3) and a piston welding-on hinge pin (5). One end of the connecting rod welding-on part (2) is connected with the crankshaft (1), and the other end is connected with the piston welding-on part (6) through the cross-shaped sleeve (4). The connecting rod welding-on part (2) and the cross-shaped sleeve (4) are connected through the connecting rod hinge pin (3). The piston welding-on part (6) and the cross-shaped sleeve (4) are connected through the piston welding-on hinge pin (5). The cross-shaped sleeve (4) is formed by welding a first sleeve (7) and a second sleeve (8). The first sleeve (7) and the second sleeve (8) are arranged in a cross-shaped axis mode. The operation is reliable, the failure rate is low, and the service life is greatly prolonged.
Description
Technical field
The utility model relates to agricultural machinery technological field, particularly a kind of piston mechanism with cross nested structure.
Background technique
At present, square bundle baler adopts mechanical type to compress substantially both at home and abroad, is commonly called as piston mechanism.Its structural principle is slidercrank mechanism, and crank rotates, and makes connecting rod ceaselessly reciprocating on guide rail with the piston that roller is housed.Piston is in reciprocal running, and roller coordinates with guide rail gapless.Guide rail is support piston not only, and control piston is upper and lower beats, and also limited piston swings.
In prior art, the Connecting format of connecting rod and piston is that Vertical direction is hinged, and substantially horizontal is rigidly connected, and in use, connecting rod not only provides power to piston movement, but also is controlling the motion of piston left and right directions.In real work, the moving direction of piston is to be controlled by guide rail and connecting rod simultaneously.So in use, some problems have been produced.
First, this mechanism, must strict guarantee piston, dimensional accuracy, morpheme error and the welding deformation of connecting rod and guide rail in the time of production and processing.So just greatly increase cost of production.
Secondly, in long-term intensive work, once connecting rod occurred level Direction distortion, certainly will cause the change of piston movement direction,, and guide rail is being controlled piston simultaneously and is moved along former direction, so, each mechanism will inevitably produce conflict, even causes immeasurable loss.
Summary of the invention
The purpose of this utility model is to provide a kind of reliable piston mechanism with cross nested structure, and this mechanism's assembling is simple, greatly reduces cost of production, meanwhile, also greatly reduces operational failure rate.
In order to realize foregoing invention object, the utility model by the following technical solutions:
With a piston mechanism for cross nested structure, comprise crankshaft (1), connecting rod seam (2), piston seam (6), cross cover (4), pitman pin (3) and piston seam bearing pin (5); Described connecting rod seam (2) one end connecting crank axle (1), the other end is connected with piston seam (6) by cross cover (4).
Above-mentioned a kind of piston mechanism with cross nested structure, described connecting rod seam (2) is connected by pitman pin (3) with cross cover (4); Described piston seam (6) is connected by piston seam bearing pin (5) with cross cover (4).
Above-mentioned a kind of piston mechanism with cross nested structure, described cross cover (4) is welded to form by sleeve first (7) and sleeve second (8), and sleeve first (7) and sleeve second (8) are cross axis arranged.
The beneficial effects of the utility model are the piston mechanisms that adopt with cross nested structure, guarantee that connecting rod and piston Connecting format is in the vertical direction hinged, also guaranteed that connecting rod and piston Connecting format is in the horizontal direction also hinged simultaneously, connecting rod just provides power to piston movement like this, the not moving direction of control piston, only have guide rail control piston movement direction, even if connecting rod deforms, also can not affect the constraint of guide rail to piston movement direction.Like this, guarantee the safe and reliable of piston operation, greatly extended working life.
Accompanying drawing explanation
Fig. 1 is the piston mechanism plan structure schematic diagram of the utility model with cross nested structure;
Fig. 2 is the piston mechanism cross nested structure schematic diagram of the utility model with cross nested structure.
In figure, each mark is as follows: 1 crankshaft, 2 connecting rod seam, 3 pitman pins, 4 cross covers, 5 piston seam bearing pins, 6 piston seam, 7 sleeve first, 8 sleeve second.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of piston mechanism with cross nested structure, comprises crankshaft (1), connecting rod seam (2), piston seam (6), cross cover (4), pitman pin (3) and piston seam bearing pin (5); Described connecting rod seam (2) one end connecting crank axle (1), the other end is connected with piston seam (6) by cross cover (4).Described connecting rod seam (2) is connected by pitman pin (3) with cross cover (4); Described piston seam (6) is connected by piston seam bearing pin (5) with cross cover (4).
As shown in Figure 2, described cross cover (4) is welded to form by sleeve first (7) and sleeve second (8), and sleeve first (7) and sleeve second (8) are cross axis arranged.
When work, power source driving crank axle (1) rotates, crankshaft (1) makes connecting rod seam (2) drive piston seam (6) reciprocating, now, connecting rod seam (2) only provides power for piston seam (6), not control piston seam (6) moving direction is moved piston seam (6) on the guide rail of adjusting.
Claims (3)
1. with a piston mechanism for cross nested structure, it is characterized in that: comprise crankshaft (1), connecting rod seam (2), piston seam (6), cross cover (4), pitman pin (3) and piston seam bearing pin (5); Described connecting rod seam (2) one end connecting crank axle (1), the other end is connected with piston seam (6) by cross cover (4).
2. a kind of piston mechanism with cross nested structure according to claim 1, is characterized in that: described connecting rod seam (2) is connected by pitman pin (3) with cross cover (4); Described piston seam (6) is connected by piston seam bearing pin (5) with cross cover (4).
