The automatic clamping and loosening device of the swing mechanism comprises a supporting body arranged at the upper end of the outer side of a swing body. The supporting body is fixedly provided with an oil cylinder and an inclined block, a piston rod is arranged inside the oil cylinder, the oil cylinder is communicated with an oil pipe of the external, and a pull rod is connected to the tail end of the piston rod. A piece of inclined iron is arranged on the outer side of the tail end of the pull rod and matched with the inclined block. A locking device is arranged on the outer side of the front end of the pull rod and comprises a locking nut pad block and a spring, and the spring presses the outer side of the supporting body. According to the automatic clamping and loosening device of the swing mechanism, a hydraulic system is used for controlling motion of the oil cylinder so that automation of the swing mechanism can be achieved, and automation degree of a machine tool or other machines can be improved.
Description
Technical field
The present invention is a kind of lathe or other machining auxiliary devices, relates in particular to a kind of automatic clamping and release device of swirl gear.
Background technique
The application of the swirl gear that moves in a circle on lathe and other relevant industries is very extensive, such as: the circular table of lathe, angle rotating machinery when mill teeth machine, gear grinding machine and gear hobbing machine are processed helical gear etc.And along with the raising to rotating accuracy requires and automaticity requires, engineers and technicians wish to increase a kind of device of automatic clamping and release when the design swirl gear, this device can play clamping action when the swirl gear state of rest, and unclamp at the Shi Zeneng that moves in a circle, can freedom and flexibility rotate, and in order to alleviate labor strength and to increase work efficiency, require the clamping of this device simultaneously and unclamp action and all realize automation by hydraulic pressure or electrical control.
Summary of the invention
The automatic clamping and release device of a kind of swirl gear that the present invention seeks to overcome the deficiencies in the prior art and provide, it be to effectively realizing the automatic clamping and release of swirl gear action, thereby improves the precision of lathe or other mechanical automaticities and part to be processed.
The object of the present invention is achieved like this: a kind of automatic clamping and release device of swirl gear, it comprises the support that is arranged on the solid of rotation outer upper end, be installed with oil cylinder and skewback on the support, be provided with piston rod in the oil cylinder, oil cylinder is communicated with the oil pipe in the external world, the piston-rod end cylinder lever connecting rod, the pull bar end outside is provided with wedge, and wedge cooperates with skewback, and the pull bar front end outside is provided with locking device, locking device comprises locking nut, cushion block and spring, the spring compression support outside.
The non-airtight end of above-mentioned oil cylinder is provided with blind flange, and blind flange is fixed on the oil cylinder by screw.
Above-mentioned piston rod and oil cylinder inner wall contact position are provided with seal ring.
Above-mentioned extraneous oil pipe is provided with pipe joint.
The terminal outside of above-mentioned wedge is provided with limiting stopper, and limiting stopper is fixed on the support by screw.
The present invention has obtained following technique effect: the present invention can realize the automation of this mechanism by the motion of HYDRAULIC CONTROL SYSTEM oil cylinder, thereby improves lathe or other mechanical automaticities.The error of having avoided the manual operation of swirl gear to bring, not only alleviated labor strength, improved working efficiency, main is Location accuracy and the repetitive positioning accuracy that this mechanism can guarantee swirl gear reliably, thereby improves the machining accuracy of part to be processed.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of automatic clamping and release device of swirl gear as shown in Figure 1, it comprises the support 2 that is arranged on solid of rotation 1 outer upper end, is installed with oil cylinder 3 and skewback 9 on the support, is provided with piston rod 4 in the oil cylinder, oil cylinder is communicated with the oil pipe 13 in the external world, piston-rod end cylinder lever connecting rod 7, the pull bar end outside is provided with wedge 8, and wedge cooperates with skewback, the pull bar front end outside is provided with locking device, locking device comprises locking nut 11, cushion block 6 and spring 10, the spring compression support outside, preferred belleville spring.The non-airtight end of described oil cylinder is provided with blind flange 5, and blind flange is fixed on the oil cylinder by screw 15.Described piston rod and oil cylinder inner wall contact position are provided with seal ring 14.Described extraneous oil pipe is provided with pipe joint 12.The terminal outside of described wedge is provided with limiting stopper 16, and limiting stopper is fixed on the support by screw.
Support of the present invention is done straight line motion at guide rail, solid of rotation moves in a circle by bearing or taper hole centering, oil cylinder is fixed on the support by screw, piston rod can side-to-side movement in oil cylinder, seal ring then plays and prevents the high pressure oil leakage effects, and two planes of wedge and skewback contact support and solid of rotation respectively, and two inclined-planes are in contact with one another, can make them produce relative movement by the piston rod pushing drawing rod, thereby realize the clamping of solid of rotation and unclamp.Other parts are fixed on the corresponding position, belleville spring by locking nut for the clamping of solid of rotation with unclamp pretightening force is provided.
Concrete working procedure is as follows: pull bar and wedge connect together by screw thread, apply locking torque at locking nut, force pull bar and wedge to axially move, skewback is fixed on the support motionless, wedge to the oil cylinder direction move eliminated and solid of rotation between the gap, when continue increasing locking torque to certain value, skewback and support, skewback and wedge, wedge and solid of rotation will effectively be locked, thereby play clamping action, the state of solid of rotation maintenance when clamping that Here it is.
When solid of rotation need rotate, in oil cylinder, feed high pressure oil through high-pressure oil pipe, piston rod is done the axial motion of dextrad, will contact with pull bar behind piston rod movement one segment distance and pushing drawing rod axially moves to the right, because wedge and pull bar connect together, so wedge also can and then move right, and will form the gap between wedge and the solid of rotation like this, namely unclamp, this moment, solid of rotation just can freedom and flexibility rotate.
When needs clamped, hydraulic system fuel cut-off, pull bar will be returned to the state that assembling is adjusted under the effect of belleville spring pretightening force, namely effectively clamped.
The quantity of the oil pressure that the size of above-mentioned locking nut pretightening force, hydraulic system provide, the quantity of belleville spring and fastening device all needs to calculate according to actual conditions.
