Description
Technical field
The utility model belongs to brick making machine apparatus field, especially relates to a kind of Bidirectional cushion cylinder of brick making machine feeding mechanism.
Background technique
At present, in brickmaking process, in order to increase work efficiency, mostly adopt oil cylinder to promote feeding, then owing to adopting manual reverse of direction in feeding process, when feeding puts in place, especially when the load of the large quality of hydraulic oil cylinder driving, because kinetic energy is excessive, can produce the violent impingement phenomenon between piston and guide sleeve, cylinder bottom at end of travel, affect greatly the working life of oil cylinder.
Summary of the invention
It is desirable that problem to be solved in the utility model is to provide a kind of cushioning effect, the Bidirectional cushion cylinder of the brick making machine feeding mechanism of long service life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of Bidirectional cushion cylinder of brick making machine feeding mechanism, comprise cylinder body, piston, connecting rod and guide sleeve, in described inner chamber of cylinder block, axle position is provided with connecting rod, connecting rod one end is provided with the piston being slidably matched with inner chamber of cylinder block, the connecting rod the other end is provided with the guide sleeve being slidably matched with it, described guide sleeve is fixed on inboard wall of cylinder block, described cylinder body is provided with oil diverting port near piston one side, described piston is divided into two cavitys by inner chamber of cylinder block, it between guide sleeve and piston, is front cavity, it between piston and cylinder body, is rear cavity, tail end cylinder body is provided with cylindrical bump on axle position therein, connecting rod is provided with the cushion hole being slidably matched with cylindrical bump near piston one end, by cushion hole, front cavity and rear cavity are connected, on the piston wall of described piston both sides, be provided with some annular rubber rings.
Described cushion hole is T shape, and this cushion hole medial axis direction section diameter is at least five times of vertical centering control axis direction section diameter.
Owing to adopting technique scheme, by the cylindrical bump being slidably matched with cushion hole, during feeding, hydraulic oil can enter front cavity from rear cavity by cushion hole, but because this cushion hole medial axis direction section diameter is far longer than vertical centering control axis direction section diameter, therefore hydraulic oil still can promote connecting rod and advances, but can slow down the speed of advancing, and reduces the piston impact force that collision produces to guide sleeve; During commutation return, cushion hole medial axis direction section is blocked by cylindrical bump and the hydraulic oil in extrusion aperture progressively, the hydraulic oil being extruded can react on cushion hole and cylindrical bump, thereby slow down the movement velocity of connecting rod and piston, reduce the impact force of piston to tail end cylinder body, realize bidirectional buffer action; In addition, the some annular rubber rings that arrange on the piston wall of piston both sides, when piston contact guide sleeve and tail end cylinder body, play the effect of secondary buffer, have extended the working life of oil cylinder in brick making machine feeding mechanism.
The beneficial effects of the utility model are: have bidirectional buffering effect ideal, the advantage of long service life.
Accompanying drawing explanation
Below by describing particularly the utility model with reference to accompanying drawing and in conjunction with example, advantage of the present utility model and implementation will be more obvious, wherein content shown in accompanying drawing is only for explaining to of the present utility model, and do not form the restriction of going up in all senses of the present utility model, in the accompanying drawings:
Fig. 1 is structural representation of the present utility model
In figure:
1, cylinder body 2, piston 3, connecting rod
4, guide sleeve 5, oil guiding hole 6, front cavity
7, rear cavity 8, cylindrical bump 9, cushion hole
10, annular rubber ring
Embodiment
As shown in Figure 1, the Bidirectional cushion cylinder of a kind of brick making machine feeding mechanism of the utility model, comprise cylinder body 1, piston 2, connecting rod 3 and guide sleeve 4, in described cylinder body 1 inner chamber, axle position is provided with connecting rod 3, connecting rod 3 one end are provided with the piston 2 being slidably matched with cylinder body 1 inner chamber, connecting rod 3 the other ends are provided with the guide sleeve 4 being slidably matched with it, described guide sleeve 4 is fixed on cylinder body 1 inwall, described cylinder body 1 is provided with oil diverting port 5 near piston 2 one sides, described piston 2 is divided into two cavitys by cylinder body 1 inner chamber, it between guide sleeve 4 and piston 2, is front cavity 6, it between piston 2 and cylinder body 1, is rear cavity 7, tail end cylinder body 1 is provided with cylindrical bump 8 on axle position therein, connecting rod 3 is provided with the cushion hole 9 being slidably matched with cylindrical bump 8 near piston 2 one end, by cushion hole 9, front cavity 6 and rear cavity 7 are connected, on described piston 2 both sides piston walls, be provided with some annular rubber rings 10, described cushion hole 9 is T shape, and these cushion hole 9 medial axis direction section diameters are at least five times of vertical centering control axis direction section diameter.
The working procedure of this example: during feeding, hydraulic oil can enter front cavity 6 from rear cavity 7 by cushion hole 9, but because these cushion hole 9 medial axis direction section diameters are far longer than vertical centering control axis direction section diameter, therefore hydraulic oil still can promote connecting rod 3 and advances, but can slow down the speed of advancing, reduce the impact force that 4 collisions of 2 pairs of guide sleeves of piston produce; During commutation return, cushion hole 9 medial axis direction sections are blocked by cylindrical bump 8 and the hydraulic oil in extrusion aperture progressively, the hydraulic oil being extruded can react on cushion hole 9 and cylindrical bump 8, thereby slow down the movement velocity of connecting rod 3 and piston 2, the impact force that reduces 2 pairs of tail end cylinder bodies 1 of piston, realizes bidirectional buffer action; In addition, the some annular rubber rings 10 that arrange on piston 2 both sides piston walls, when piston 2 contact guide sleeves 4 and tail end cylinder body 1, play the effect of secondary buffer, have extended the working life of oil cylinder in brick making machine feeding mechanism.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model scope and improvement etc., within all should still belonging to this patent covering scope.
