Description
Technical field
The present invention relates to field of machining, particularly the fixture carrying out Quick-clamped to workpiece behind workpiece location.
Background technology
At present, during machining, after workpiece positions on the fixture of platen, Workpiece clamping acts on what workpiece realized with unclamping typically via briquetting.Realize said process and mainly have following several ways:
One, mechanical type: twist nut by spanner and screw with screw rod, it is achieved the axially-movable of the relative screw rod of nut, and act on briquetting.This screw rod is in the centre of briquetting, and there is support one end of briquetting, and another acts on workpiece.It has the drawback that need to carry out with spanner, when clamping point is more, take time and effort very much, inefficiency when clamping workpiece and dismounting.
Two, fluid pressure type: by the cylinder efficient in hydraulic system, the pull bar of oil cylinder is connected with briquetting, when oil cylinder backward stick action, briquetting pursuit movement, thus realizing the clamping to workpiece and unclamping.It has the drawback that hydraulically operated fixture and lathe are that the product for a kind of batch machining carries out special, and the oil circuit of hydraulically operated fixture is placed in platen, and cylinder efficient position is also that relative processing work has designed and fixed.When batch machining replacement of products kind, its oil circuit, the clamping point position of hydraulically operated fixture, cylinder efficient position need specialized factory to redesign layout, change extremely difficult.Hydraulically operated fixture also has cost high, oil consumption power consumption, the shortcomings such as maintenance workload is big.
Three, vapour-pressure type: the pull bar of cylinder is connected with briquetting, when air cylinder tie rod action, briquetting pursuit movement, thus realizing the clamping to workpiece and unclamping.It has the drawback that air-actuated jaw and lathe are that the product for a kind of batch machining carries out special, when batch machining product is replaced kind, is suitable for difficulty.Air clamp has clamping force inadequate, and it is unreliable etc. to clamp.
Summary of the invention
For the deficiency of above-mentioned mechanical type, fluid pressure type and vapour-pressure type fixture, when it is an object of the invention to provide Workpiece clamping and unclamp, work efficiency is high, it is readily replaceable to change fixture during product, the fixture of the reliable a kind of Quick-clamped of clamping force.
The fixture of this Quick-clamped, it is characterized in that, including 23, workpiece is implemented the briquetting of clamping, described briquetting is all connected with same float plate, float plate relies on the support of spring, is provided with lever between float plate and workpiece, and middleware contacts with lever and float plate respectively, lever one end is fulcrum and position of the fulcrum governor motion, and the other end of lever is power point and corresponding actuating unit.
Briquetting is connected to two ways with float plate: direct and float plate chain connection, it is possible to be connected by connecting rod with float plate.
Floating of float plate relies on the support of spring, and support pattern has two kinds, and one is to arrange spring in float plate bottom, and one is to be hung by float plate spring.
The center of gravity of described briquette structure in corresponding roller side, described briquetting under Gravitative Loads with described corresponding roller contact.
Described position of the fulcrum governor motion, including the top board of two columns being fixed on substrate and column upper end, column both sides have gathering sill, and balance pivot is lever both sides straight pins, described straight pin is placed in the bearing being made up of base and upper cover, and a bearing two ends is placed in described gathering sill；This bearing arrangement is releasable structure symmetrical above and below, and a bearing bottom is by spring supporting；Screwed hole is had in the middle of the top board of governor motion, adjusting nut screws with screwed hole and contacts with upper cover through top board, by the position of adjusting nut scalable balance pivot, and then by lever, middleware, float plate transmission power, it is achieved the adjustment of the clamping distance of briquetting and workpiece.
Described position of the fulcrum governor motion can also have following form: including the top board of two columns being fixed on substrate and column upper end, column both sides have gathering sill, and balance pivot is lever both sides straight pins, and described straight pin is placed in described gathering sill；Having screwed hole in the middle of the top board of governor motion, adjusting nut and screwed hole screw through top board and lever contact, by the position of adjusting nut scalable balance pivot.
Described to force mechanisms, including a cam, cam is arranged in cam post, and cam post is fixed on substrate, and camshaft is felt at ease equipped with one handle, lever end is provided with one to power roller, cam and give power roller contact, pull handle with hands, cam rotation can be driven, utilize cam by transmitting the force to lever to power roller, make lever motion.
The structure of described middleware is not intended to described float plate and rotates in three directions in space, is also not intended to act on the movement of the force direction in described float plate simultaneously, and middleware contacts with float plate as sphere-contact or linear contact lay；Distance between float plate and lever is 0 ~ 120mm, and when spacing is zero, described middleware is considered as cancelling.
One end of described lever is position of the fulcrum, and the other end of lever is to the position of action point of force mechanisms power, and the position of action point of the resistance of lever is between the position of action point of described position of the fulcrum and described power；The application point of resistance is called resistance arm to the distance of fulcrum, to the distance of fulcrum, the application point of power is called that power arm, described power arm length are 1.2 times to 4 times of resistance arm length；
Described cam girth is divided into working region, locking region and quick relieved areas, and quick relieved areas is a straight line string；Working region is the curve constantly increased from cam axle center distance, and the difference range of the described origin of curve distance from described cam axle center and the End of Curve distance from described cam axle center is 2 ~ 150mm；Locking region is the circular arc that one section of center of circle is concentric with camshaft hole.
The invention have the advantage that this fixture is to after workpiece locking member, can to workpiece Quick-clamped；When workpiece is not compressed by each briquetting in fixture simultaneously, float plate can be automatically adjusted when described middleware transmits power, and realizes the clamping to workpiece；Improve the clamping work efficiency of workpiece.
