Description
Technical field
Servomotor is buffered the present invention relates to a kind of external regulation type stroke.
Background technology
Water conservancy system promotes the servomotor of weight, in the course of the work, due to weight own wt, for anti-non-return
The enormous impact that journey is produced causes damage to servomotor structure, therefore buffer gear is typically provided with inside servomotor, but existing connects
The cushion collar stroke of buffer gear used in power device is typically fixed, it is impossible to implemented in use according to impulsive force size
Regulation, adaptability is not enough.
The content of the invention
The technical problem to be solved in the present invention is：In order to overcome deficiency in the prior art, the present invention provides one kind can root
The external regulation type stroke for implementing stroke adjustment at any time according to onsite application situation buffers servomotor.
The technical solution adopted for the present invention to solve the technical problems is：A kind of external regulation type stroke buffers servomotor, including
Cylinder body, the piston and cylinder bottom being slidably matched with inboard wall of cylinder block, described piston offer cushion hole, cylinder bottom towards cylinder bottom side
Mounting hole corresponding with buffering hole site is inside offered, is provided with cushion collar, cushion hole and sets between the cushion hole and mounting hole
Have in the copper sheathing being slidably matched with cushion collar, mounting hole provided with the screw rod being threadedly coupled with cushion collar rearward end, mounting hole rear end
Place is provided with hollow fixed cover, and spiro rod rear end portion rotates the hollow intracavitary positioned at fixed cover.
There is transfer phenomenon in cushion collar during to prevent that regulation from rotating screw rod, and described cushion collar rearward end has been radially inserted into circle
Post spacer pin, installing has the chute being slidably matched with cylinder spacer pin bottom on hole wall.
To improve servomotor sealing, described fixed cover is threadedly coupled with mounting hole, in fixed cover outer wall and mounting hole
O-ring seals are respectively equipped between wall, between screw rod outer peripheral face and fixed cover interior walls.
The beneficial effects of the invention are as follows：The present invention promotes cushion collar reach or retreated, reach requirement by rotating screw rod
Fixing nut is screwed on during stroke again, it is easy to operate, the buffering needs of different impulsive forces can be met, protection cylinder body, cylinder is reached
The purpose at bottom.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
In figure：1. the screw rod 9. of 7. copper sheathing of cylinder body 2. piston, 3. cylinder bottom, 4. cushion hole, 5. mounting hole, 6. cushion collar 8.
The chute 12.O shape sealing rings of 10. cylinder spacer pin of fixed cover 11.
Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of external regulation type stroke buffering servomotor as shown in Figure 1, including the work that cylinder body 1 and the inwall of cylinder body 1 are slidably matched
Plug 2 and the cylinder bottom 3 for being fixed on cylinder body bottom.The line direction described below using before piston 2 is front.
Described piston 2 offers cushion hole 4 towards the side of cylinder bottom 3, and sealing is fixed with copper at the rear port of cushion hole 4
Mounting hole 5 axially through cylinder bottom 3 and consistent with the center of cushion hole 4 is offered in set 7, cylinder bottom 3, the cushion hole 4 is with installing
Cushion collar 6 is provided between hole 5, the cushion collar 6 is slidably matched with the endoporus of copper sheathing 7 and mounting hole 5 respectively, the rear end of mounting hole 5
Hollow fixed cover 9 is installed, described fixed cover 9 is threadedly coupled with mounting hole 5, be provided with and the rear end of cushion collar 6 in mounting hole 5
The screw rod 8 of portion's threaded connection, the rotating part of screw rod 8 rotates the hollow intracavitary positioned at fixed cover 9, while the rear end of screw rod 8 stretches out solid
Surely set 9 is outer and is connected with the fixing nut that regulation finishes standing screw 8.
The front end of the cushion collar 6 has 30 degree of chamfering, and the endoporus rear end of copper sheathing 7 equally has chamfering, moved back in piston 2
Hui Shi, cushion collar 6 puts in copper sheathing 7 by the positioning action of chamfering and is slidably matched.
There is transfer phenomenon in cushion collar 6 during to prevent that regulation from rotating screw rod 8, and the described rearward end of cushion collar 6 is radially inserted into
There is cylinder spacer pin 10, there is the chute 11 being slidably matched with the bottom of cylinder spacer pin 10 on the wall of mounting hole 5；In addition in fixation
Cover between 9 outer walls and the inwall of mounting hole 5, be respectively equipped with O-ring seals 12 between the outer peripheral face of screw rod 8 and the interior walls of fixed cover 9, to improve
The overall sealing of servomotor.
When needing to adjust the cushion stroke of servomotor according to on-site actual situations, fixing nut only need to be backed out.Rotate spiral shell
Bar 8, promotes cushion collar 6 to move forward or retreat, fixing nut is screwed on again during the stroke for reaching requirement.It is easy to operate, it can meet
The buffering of different impulsive forces needs, and protection cylinder body 1, cylinder bottom 3 are injury-free.
Using the above-mentioned desirable embodiment according to the present invention as enlightenment, by above-mentioned description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to its technical scope is determined according to right.
