Advantages of the use of liquid rising fixture
As we all know, in the processing of the workpiece, reduce downtime for repair is to improve productivity, is an important production capacity Z, and in the process of processing the precise positioning and clamping repeatability is also the key to improve efficiency and quality.
In the high-precision workpiece processing, ordinary arbor due to easy to produce large runout and difficult to achieve the process requirements, and in the current fixture technology support, liquid up fixture is to solve the thin-walled processing, hobbing / gear shaping processing and other high-precision work of one of the best choice.
Liquid up fixture is a kind of product workpiece to carry out automatic positioning, clamping and support of special tools, and ordinary hydraulic fixture is different is that the liquid up fixture is the use of hydrostatic expansion technology, the fixture is pressurized, the hydraulic medium under the action of the pressurizing mechanism to generate great pressure, forcing the deformation components in the entire clamping range of 360 ° circumferential uniform elastic deformation, to achieve the positioning of the workpiece hole / the expansion of the tightening The hydraulic pressure mechanism produces great pressure, forcing the deformation element to deform uniformly in 360° circumferential elasticity throughout the clamping range to achieve the expansion and tightening of the workpiece positioning hole.
The hydraulic clamping fixture has the following advantages in use.
(1) to ensure processing accuracy
The use of hydraulic clamping installation and positioning, can quickly and accurately determine the mutual position between the workpiece and the machine tool, the position of the workpiece accuracy, not affected by the level of skill of workers to ensure processing accuracy and continued stability.
(2) Improve production and reduce costs
The use of hydraulic clamping fixture clamping workpiece, can be quickly positioned and clamped, greatly reducing the time of loading and unloading workpiece; clamping workpiece with hydraulic clamping fixture to improve the rigidity of the workpiece, so you can increase the cutting amount, you can use multiple pieces, multi-station clamping fixture clamping workpiece, and the use of efficient clamping mechanism, these factors are conducive to improving labor productivity and safety, product quality and stability, the scrap rate decreased, effectively reducing production costs (3) Multiple size workpieces
(3) Processing of workpieces of various sizes and specifications
The use of reducer clamps, spline clamps and other accessories can achieve a variety of sizes and specifications of workpiece processing, no longer limited to the traditional processing of a single workpiece, effectively improving productivity and reducing the loading and unloading time.
(4) expand the scope of the machine tool process
The use of liquid up fixture can change the use of the original machine tool and expand the scope of application of the machine tool, to achieve a multi-purpose machine, effective savings in production costs.
(5) Reduce the labor intensity of workers
The use of liquid up jig clamping workpiece convenient, safe, fast, can reduce the labor intensity of workers.
Therefore, the application of the liquid up jig almost the whole scene range, can be applied in gear processing, gear shaping, grinding, hobbing, shaving, gear testing and other aspects, can also be used for lathe, cylindrical grinding of thin-walled processing clamping.
