Abstract
The utility model belongs to a mechanical control technology and particularly discloses a torque adjustable damper. The torque adjustable damper comprises a casing, wherein a torque output shaft is arranged in the casing, a bearing is sheathed on the shaft, a cylindrical bulge is arranged at the upper end of the casing, a through hole is formed in the cylindrical bulge, a press spring is arranged in the through hole, and a twisting preventive slide block is arranged below the press spring; a press wheel is sheathed on the torque output shaft, and the twisting preventive slide block is in contact with a bus of the press wheel. The press spring generates a downward force which is acted on the press wheel by the twisting preventive slide block and is acted on a bus of a hub by the press wheel, and the rotation of a rotating shaft generates certain damping action, so that use requirements of a horizontal tension system are met; furthermore, a torque adjustable knob is designed to enable the downward force of the press spring to be controllable, so that the friction between the torque output shaft and the press wheel is controllable so as to control the rotating torque of the torque output shaft, so that the use reliability of the whole equipment is improved.
Description
Technical field
The utility model belongs to mechanical control technology, is specifically related to a kind of adjustable damper.
Background technology
Existing numerically controlled wire cutting machine, what adopt in its constant tension control system is that magnetic damper is realized the permanent Tension Control to wire electrode; Its structure is complicated.Along with the decay of magnetic force, can't reach the moment requirement when using, so the life-span is shorter, the numerically controlled wire cutting machine of external import costs an arm and a leg in addition, and the introduction cycle is longer.Therefore need a kind of substitute of development, satisfy the demand of producing and using.
The silk of being careful of lathe will be tightened, and generally adopts will the be careful end tension of silk of tensioning mechanism, and the other end need oppositely draw the silk of being careful, and backward rotation can not be too violent, therefore need design to be careful a tumbler that silk oppositely draws.
Summary of the invention
The purpose of the utility model be to provide a kind of can be careful the silk oppositely draw and the adjustable damper of torque that velocity of rotation is controlled.
The technical scheme of the utility model is following:
The adjustable damper of a kind of torque, it comprises housing, is provided with the torque output shaft in the described housing; Be set with bearing on the torque output shaft, described housing upper end is provided with cylindrical protrusions, is provided with through hole in this cylindrical protrusions; Be provided with stage clip in the through hole, stage clip has the anti-slide block of turning round; Be set with pinch roller on the described torque output shaft, and above-mentionedly anti-turn round slide block and contact with the bus of this pinch roller.
In the adjustable damper of above-mentioned torque: be provided with external screw thread on the described cylindrical protrusions, above this cylindrical protrusions, be provided with the torque adjusting knob, this torque adjusting knob inwall is provided with internal thread, and torque adjusting knob and cylindrical protrusions are through being threaded.
In the adjustable damper of above-mentioned torque: the right side of said housing is provided with axis hole, and described torque output shaft is positioned at this axis hole, and is provided with right bearing between the inner walls of torque output shaft.
In the adjustable damper of above-mentioned torque: the left end of described torque output shaft is set with wheel hub, and wheel hub is positioned at enclosure interior, and the left side of wheel hub is provided with end cap, and this end cap is fixedly connected through screw with the left end of housing.
The beneficial effect of the utility model is: because stage clip produces a downward power; This power is through preventing that turning round slide block affacts on the pinch roller; Affact through pinch roller on the bus of wheel hub, make the rotation of rotating shaft produce certain damping action, thereby reach the instructions for use of horizontal tension system; Further, through the design moment adjusting knob, the power that stage clip is pressed down is controlled, thereby makes that the friction between torque output shaft and the pinch roller is controlled, thus the driving torque of controlling torque output shaft, and the reliability that makes entire equipment use improves.
Description of drawings
Fig. 1 is the adjustable damper sketch map of the torque of the utility model;
Among the figure: 1. housing; 2. torque output shaft; 3. end cap; 4. wheel hub; 5. pinch roller; 6. the anti-slide block of turning round; 7. stage clip; 8. torque adjusting knob; 9. left bearing; 10. right bearing; 11. cylindrical protrusions.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain.
As shown in Figure 1, circular pinch roller 5 center fixation are equipped with torque output shaft 2, when torque output shaft 2 rotates, can drive pinch roller 5 and together rotate.In the left side of torque output shaft 2 left bearing 9 is housed, and outside left bearing 9, wheel hub 4 is installed.
As shown in Figure 1, housing 1 is columnar structured, its left end opening; Its right side is processed with axis hole; The upper end is processed with cylindrical protrusions 11, and should be processed with through hole on the convexity, in through hole, places stage clip 7; An anti-slide block 6 of turning round is installed below stage clip 7, and this anti-lower surface of turning round slide block 6 contacts with the bus of pinch roller 5.
The torque output shaft 2 that pinch roller 5 and wheel hub 4 are installed is packed in the housing 1 through the axis hole of the bottom of housing 1, and right bearing 10 is installed between torque output shaft 2 and housing 1.Left end at housing 1 fixedly mounts end cap 3 through screw at last.
Work compresses stage clip 7, makes stage clip 7 press down the anti-slide block 6 of turning round, and makes and prevents that turning round slide block 6 compresses pinch roller 5, and frictional force increases between pinch roller 5 and the torque output shaft 2, thereby the rotation slowing of torque output shaft 2.
In order to make the rotation of torque output shaft controlled; Outer wall threading in cylindrical protrusions 11; A torque adjusting knob 8 is installed above cylindrical protrusions 11; The inwall of this torque adjusting knob 8 is processed with internal thread, and torque adjusting knob 8 passes through thread set in the outside of cylindrical protrusions 11, and compresses the stage clip 7 in cylindrical protrusions 11 through holes.Through 8 times stubborn positions of control moment adjusting knob, the power that makes stage clip 7 compress downwards is controlled, thereby makes that the frictional force between pinch roller 5 and the torque output shaft 2 is controlled, thereby makes that the driving torque of torque output shaft 2 is controlled.
