Abstract
The invention relates to a spring fixture for clamping a high-speed rotating workpiece. The spring fixture comprises a cone-shaped seat and a supporting disk; a cavity is vertically arranged in the middle of a base; a lower pull rod is installed in the cavity; the middle of the lower pull rod is sleeved with a butterfly-shaped spring; the upper end of the butterfly-shaped spring abuts against the upper wall of the cavity and the lower end of the butterfly-shaped spring abuts against a circle of baffle arranged around the lower pull rod; a screw is horizontally arranged on the portion, above the cavity, of the base; one end of the screw stretches into a sliding groove arranged vertically in the lower pull rod; the supporting disk is installed at the upper end of the base; the cone-shaped seat is vertically arranged between the supporting disk and the base; a screw rod is vertically arranged in the cone-shaped seat; the upper end of the screw rod is connected with an expanding sleeve connected with the upper portion of the cone-shaped seat in a sleeving mode and the lower end of the screw rod passes through the cone-shaped seat and is connected with the lower pull rod. According to the spring fixture for clamping the high-speed rotating workpiece, the butterfly-shaped spring is used to replace an air cylinder and an oil cylinder to clamp the workpiece, and the air cylinder and the oil cylinder are used to compress the spring in need of loosening the workpiece. The use of the butterfly-spring has the advantages that clamping is reliable and the adjustment of clamping force is convenient. The spring fixture has the characteristics that travelling is short and loading is large.
Description
Technical field
The present invention relates to clamp art, more particularly to a kind of spring perch for clamping high speed rotational workpieces.
Background technology
For the workpiece of high speed rotation, general clamping mode takes air pressure or oil pressure to clamp mostly.This is because its
The advantages of with low cost, fast response time.But once power failure or electrical fault are run into, oil cylinder can be failed at once with cylinder.
And workpiece now is still rotated in high speed, therefore this easily causes the generation of security incident.
The content of the invention
The technical problem to be solved is to provide a kind of spring perch for clamping high speed rotational workpieces, uses
Butterfly spring replaces cylinder, oil cylinder to clamp workpiece, uses cylinder, oil cylinder again by spring-compressed when needing to unclamp workpiece.Using butterfly
The benefit of spring is exactly reliable clamping, and the regulation of clamping force is also more convenient, short with stroke, load it is big the characteristics of.
The technical solution adopted for the present invention to solve the technical problems is：There is provided a kind of for clamping high speed rotational workpieces
Spring perch, including base, conical seat and support disk, are vertically disposed with the middle part of described base in cavity, the cavity and install
There is lower pull bar, in the middle part of described lower pull bar, be cased with butterfly spring, the upper wall of cavity, described butterfly are withstood in the butterfly spring upper end
Lower spring end withstands a circle baffle plate of lower pull bar arrangement, and described base is located above cavity and is horizontally installed with screw, the screw
One end extend into lower pull bar vertically in the chute of arrangement, and described base upper end is provided with support disk, the support disk and bottom
It is vertically-mounted between seat to have conical seat, vertically-mounted in described conical seat to have screw rod, upper end and the conical seat top of the screw rod
The ringfeder of socket is connected, and the lower end of the screw rod told is connected through conical seat with lower pull bar.
Supplement as the one kind to technical solutions according to the invention, the screw rod upper end told is disposed with circle projection, should
The raised draw-in groove with ringfeder inwall arrangement interlocks.
Supplement as the one kind to technical solutions according to the invention, described lower pull bar is threaded connection with screw rod.
Supplement as the one kind to technical solutions according to the invention, described lower pull bar lower end is located at the lower section of baffle plate and pacifies
Equipped with circlip for hole.
Beneficial effect：The present invention relates to a kind of spring perch for clamping high speed rotational workpieces, using butterfly spring generation
Workpiece is clamped for cylinder, oil cylinder, cylinder, oil cylinder is used when needing to unclamp workpiece again by spring-compressed.Using the benefit of butterfly spring
Be exactly reliable clamping, and the regulation of clamping force be also more convenient, it is short with stroke, load it is big the characteristics of.
