Description
Technical field
The utility model relates to excavating machine accessory technical field, especially a kind of bidirectional buffering tightening device.
Background technology
Traditional excavating machine is provided with a recoil spring with track takeup, support is connected with tensioning hydro-cylinder, cushion be to a certain extent the hit power of force direction of crawler belt, but after having impacted, outer impulsive force disappears, recoil spring homing hits can to again recoil of support of tightening device, cause the pretension bearing of support to be subject to an impulsive force, cause the damage of support, in the situation that operating mode is severe and be frequently hit in situation, more can cause the havoc of support, and then cause pretension bearing to lose efficacy, more severe patient is scrapped whole tightening device.
Utility model content
The utility model, for the deficiencies in the prior art, proposes a kind of bidirectional buffering tightening device, has realized bidirectional buffering when tightening device is stressed with recoil spring restoring force, has avoided the damage of the tightening device support causing thus.
In order to realize above-mentioned utility model object, the utility model provides following technical scheme:
A kind of bidirectional buffering tightening device, comprises support, buffering connecting rod, tensioning hydro-cylinder and recoil spring, described buffering connecting rod one end through described tensioning hydro-cylinder and with described tensioning hydro-cylinder bearing fit, described recoil spring connects described support and described tensioning hydro-cylinder,
Also comprise bounce cylinder, described bounce cylinder is the uncovered cell body in one end,
Described support is arranged on described bounce cylinder periphery,
Described buffering connecting rod is connected with piston through the base plate of described bounce cylinder away from one end of described tensioning hydro-cylinder, bearing fit between described piston and described bounce cylinder inwall,
On the sidewall near described base plate position, bounce cylinder, have pore, described base plate and corresponding position, described pore position are provided with tapped through hole, adjust bolt and coordinate with described tapped through hole in the described pore of insertion.
Further, also have induction opening at the sidewall of described bounce cylinder near described base plate place, on described induction opening, be provided with one-way air inlet valve gap.
Further, described one-way air inlet valve gap is tabular, its be arranged on described induction opening be positioned on the port of described bounce cylinder inwall one end, hinged and cover this port of described induction opening by torsion spring with described bounce cylinder inwall.
Further, between described piston and described bounce cylinder inwall, and be provided with sealing layer between buffering connecting rod and described base plate.
A kind of bidirectional buffering tightening device of the utility model, by the design to this structure of bounce cylinder, has realized bidirectional buffering when tightening device is stressed with recoil spring restoring force, has avoided the damage of the tightening device support causing thus.
Brief description of the drawings
Fig. 1 is the schematic diagram of a kind of bidirectional buffering tightening device described in the utility model;
Fig. 2 is the local enlarged diagram of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
A kind of bidirectional buffering tightening device as depicted in figs. 1 and 2, comprise support 1, buffering connecting rod 2, tensioning hydro-cylinder 3 and recoil spring 4, buffering connecting rod 2 one end through tensioning hydro-cylinder 3 and with tensioning hydro-cylinder 3 bearing fits, recoil spring 4 connection brackets 1 and tensioning hydro-cylinder 3,
Also comprise bounce cylinder 5, bounce cylinder 5 is the uncovered cell body in one end,
Support 1 is arranged on bounce cylinder 5 peripheries,
Buffering connecting rod 2 is connected with piston 6 through the base plate 51 of bounce cylinder 5 away from one end of tensioning hydro-cylinder 3, bearing fit between piston 6 and bounce cylinder 5 inwalls,
On the sidewall near base plate 51 positions, bounce cylinder 5, have pore 52, base plate 51 is provided with tapped through hole with pore 52 corresponding positions, position, adjusts bolt 53 and coordinates with tapped through hole in insertion pore 52.Adjust bolt 53 for regulating pore 52 to pass in and out the size in the space of air-flow, to regulate the power of buffer action.
Sidewall at bounce cylinder 5 also has induction opening 54 near base plate 51 places, is provided with one-way air inlet valve gap 55 on induction opening 54.
One-way air inlet valve gap 55 is tabular, its be arranged on induction opening 54 be positioned on bounce cylinder 5 inwall one end ports, hinged and cover this port of induction opening 54 by torsion spring with bounce cylinder 5 inwalls.
Between piston 6 and bounce cylinder 5 inwalls, and be provided with sealing layer between buffering connecting rod 2 and base plate 51.
When use, when recoil spring 4 is under pressure, the relative bounce cylinder 5 of piston 6 is to bounce cylinder 5 open-mouth motions, under atmospheric effect, breather cheek valve lid 55 is opened, air enters in bounce cylinder 5, in the time that recoil spring 4 resets, the relative bounce cylinder 5 of piston 6 is to bounce cylinder 5 base plate 51 places motions, now the interior gas of bounce cylinder 5 compresses one-way air inlet valve gap 55, discharge by pore 52, owing to by adjusting bolt 53, pore 52 cross sectional dimensions being turned down, reduce the speed of exhaust, and then reduce the speed that recoil spring 4 resets, realize buffering.
Be corresponding valve gap if induction opening 54 is not set, only still can realize the pooling feature of bounce cylinder 5 by pore 52, just input and output gas is all to have pore 52 to realize, and bounce cylinder 5 itself can be realized bidirectional buffering.
A kind of bidirectional buffering tightening device of the utility model, by the design to this structure of bounce cylinder, has realized bidirectional buffering when tightening device is stressed with recoil spring restoring force, has avoided the damage of the tightening device support causing thus.
