Description
Technical field
The present invention relates to technical field of engineering machinery, especially a kind of accessory connector with limit function and adaptive damping function.
Background technology
The connector of accessory is one comparatively conventional in numerous connectors of using of excavator, and it plays the effect be connected with operation accessory and dipper.Existing excavator accessory connector adopts the form of single mount connector mostly, and it comprises welding bearing and a bearing pin, is directly connected with dipper by the bearing of bearing pin by welding.The connector of this structure, owing to not having limit function, because accessory rocks in operation process, often causes itself and dipper to collide.Simultaneously owing to not having damping action, rocking of causing in lifting process usually cannot stop at short notice, badly influences the stability of operation and the comfortableness of operation.
Summary of the invention
The object of this invention is to provide a kind of with spacing and accessory connector that is mutative damp function, this connector can solve the problem that existing accessory connector easily collides and rocks in operation process.
In order to solve the problem, the technical solution used in the present invention is: the spacing and accessory connector that is mutative damp function of this band comprises the accessory mount pad by pinned connection dipper bearing, described bearing pin is set with the frictional disk between end face and described accessory mount pad being arranged at described dipper bearing, be provided with by motor-driven feed bar in described accessory mount pad side, the free end of described feed bar is provided with the damper abutted against with described frictional disk, described accessory mount pad is provided with force snesor, and described sensor and described motor are electrically connected with controller.
In the technical scheme of the accessory connector of the spacing and mutative damp function of above-mentioned band, technical scheme can also be more specifically: described frictional disk outer face be provided with projection, described accessory mount pad has the defining flange limiting described projection.
Further, the side of described accessory mount pad is welded with guide pad, described guide pad is provided with the screwed hole be threaded with described feed bar, and described accessory mount pad offers the through hole coaxially arranged with described screwed hole, described damper is placed in described through hole.
Further, described frictional disk is fixedly connected with described dipper bearing.
Further, described frictional disk outer face and described damper friction factor are between 0.35 ~ 0.65.
Further, described motor is stepper motor.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the mutual rubbing action of damper and frictional disk outer face is set and plays braking action, avoid accessory and rock, decrease the possibility that accessory and dipper collide simultaneously; Arrange force snesor and stepper motor, adjustable dampers realizes suppressing slosh damping to change with accessory magnitude of load, to reach under different accessory load to reduce as far as possible simultaneously and rocks number of times, thus improve job stabilization and operation comfort.
2, by arranging boss in frictional disk outer face and arrange the defining flange that coordinates with boss on accessory mount pad, position-limiting action is played to accessory mount pad swing corner, thus effectively prevent accessory and dipper collides.
3, guide pad is set, for controlling moving axially of damper.
4, frictional disk outer face has larger frictional resistance, can guarantee effective brake.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Band shown in Fig. 1 is spacing mainly comprises frictional disk 2, accessory mount pad 3, force snesor 4, motor, controller 6, feed bar 7 and damper 8 with accessory connector that is mutative damp function, wherein, motor adopts stepper motor 5, accessory mount pad 3 is connected with dipper 1 bearing by bearing pin 9, frictional disk 2 to be sleeved on bearing pin 9 and between the end face being placed in dipper 1 bearing and accessory mount pad 3, dipper 1 seat end surface has attacked screwed hole, and frictional disk 2 is arranged on dipper 1 seat end surface by bolt; Guide pad 10 is welded with in accessory mount pad 3 side, guide pad 10 is threaded feed bar 7, one end of feed bar 7 arranges the damper 8 abutted against with frictional disk 2, damper 8 is placed in a through hole of accessory mount pad 3, the screwed hole of this through hole and guide pad 10 is coaxially arranged, the other end of feed bar 7 is connected with the output shaft of stepper motor 5, and stepper motor 5 is also installed on accessory mount pad 3; The accessory that force snesor 4 is installed on accessory mount pad 3 installs pin-and-hole top, and controller 6 is electrically connected with stepper motor 5 and force snesor 4 respectively, and controller 6 by force snesor 4 signals collecting, and controls stepper motor 5 by set control strategy.When connector bottom accessory picks up load change, force snesor 4 is by signal feedback to controller 6, and controller 6 control step motor 5 drives feed bar 7 to adjust the amount of feeding of damper 8; Damper 8 and frictional disk 2 interact connector played slow down, cushioning effect, frictional disk outer face should have larger frictional resistance, frictional disk outer face and described damper friction factor are between 0.35 ~ 0.65, frictional force between damper 8 from frictional disk 2 is different and change with the amount of feeding of damper 8, thus realizes suppressing slosh damping to change with accessory magnitude of load.
As accompanying drawing 2, the control strategy of controller 6 pairs of stepper motors 5 of the accessory connector of the present embodiment is: the accessory load G that the amount of feeding s that stepper motor 5 exports damper to inputs to controller 6 with force snesor 4 is line style change.
It is worth mentioning that, accessory connector is provided with position limiting structure, and as shown in Figures 3 to 5, frictional disk 2 outer face is provided with boss 2-1, frictional disk 2 outer face should have larger frictional resistance, can play good braking action when interacting with damper 8; The side plate of accessory mount pad 3 is provided with the first defining flange 3-1 and the second defining flange 3-2, the projection 2-1 of frictional disk 2 is in the slewing area of two defining flanges, swings corner play position-limiting action to accessory mount pad 3.In the course of the work, when lower limit position, position-limiting action is played to accessory mount pad 3 first defining flange 3-1 in boss 2-1 lower surface, frictional disk 2 outer face; When upper limit position, position-limiting action is played to accessory mount pad 3 second defining flange 3-2 in boss 2-1 upper surface, frictional disk 2 outer face, and then realize spacing relative to dipper 1 high-low limit position of connector, reach the situation avoiding connector and dipper 1 to collide at work and occur.
