Abstract

The invention relates to a torsional spring for a potato machine, which is provided with a cylindrical spring body with outer diameter of 15mm, two opposite ends of the spring body respectively extend to form a long spring arm and a short spring arm, the axial angle of the long spring arm and the spring body is 13 degrees, the axial angle of the short spring arm and the spring body is 55 degrees, the tail end of the long spring arm is outwards bent with 13 degrees and then vertically connected with a right-angle hook, and the tail end of the short spring arm is forwards bent to form an arc hook. The invention has the advantages that the tail end of the short spring arm is forwards bent to form the arc hook so as to be convenient to be hung on a frame of a tomato machine rotating seat, the long spring arm is outwards bent with 13 degrees and then vertically connected with the right-angle hook so as to be convenient to be hung in a hanging hole of a movable tool rest, the movable tool rest is clamped on the tomato machine rotating seat under the action of the torsional force, and the long spring arm can rotate around a bottom shaft of the movable tool rest under the action of an outside force; and the torsional spring has simple structure and is suitable for being matched with the tomato machine for use.

Description

A kind of potato machine torsion spring

Affiliated technical field

The present invention relates to a kind of torsion spring, relate in particular to a kind of and the matched torsion spring of potato machine.

Background technique

The torsion spring of in daily life, using, generally be to constitute by columniform spring body and two bending spring arms, and in actual applications, since torsion spring the structure of supporting product different and to the greatest extent unsuitable mutually, the torsion spring of using on existing a kind of potato machine, because the particularity of its structure, the structure of general torsion spring does not reach its performance requirement, need make certain improvements to existing spring arm.

Summary of the invention

The objective of the invention is provides a kind of potato machine torsion spring at above-mentioned stating, terminal special hook structure, the next satisfied and supporting demand of potato machine of adopting of spring arm.

The object of the present invention is achieved like this: a kind of potato machine torsion spring, be provided with columniform spring body, the external diameter of spring body is 15mm, two opposite ends of spring body are extended the length tangent with the spring body respectively, short spring arm, long spring arm and spring body angle longitudinally are 13 °, short spring arm and spring body angle longitudinally are 55 °, the vertical right angle hook that connects after 13 ° of the terminal outwards bendings of long spring arm, the terminal distance to the axle center of long spring arm is 30.3mm, described right angle hook is combined by orthogonal long limit and minor face, the right angle hook top is 37.8mm to the distance in axle center, the length on long limit is 6.0mm, the length of minor face is 5.0mm, the length of short spring arm is 10.0mm, short spring arm tip forward is bent into the arc hook, arc hook top is 14mm to the distance in axle center, it is that the Spring Steel Wire coiling of 1.5mm forms that the present invention adopts diameter, during use the spring body is enclosed within on the lower shaft of potato machine knife rest alive, arc hangs on the framework of potato machine swivel base, right angle hook hangs over the hanging hole of knife rest alive from the knife rest back side of living, be stuck on the potato machine swivel base at following knife rest alive of twisting force, be pulled outwardly knife rest alive, can drive long spring arm and rotate, reset by the elastic and drive the work knife rest and reset thereby unclamp the torsion spring external force effect under around the lower shaft of the knife rest of living.

Advantage of the present invention is, short spring arm tip forward is bent into the arc hook, be convenient to hang on the framework of potato machine swivel base, the vertical right angle hook that connects is convenient to hang in the hanging hole of knife rest alive after 13 ° of the outside bendings of long spring arm, the knife rest of living can be stuck on the potato machine swivel base under twisting force, under external force, long spring arm can rotate around the lower shaft of the knife rest of living, and it is simple in structure, is suitable for and the supporting use of potato machine.

Description of drawings

Fig. 1 is a plan view of the present invention;

Fig. 2 is a left view of the present invention.

Among the figure: 1, spring body; 2, long spring arm; 3, lack the spring arm; 4, arc hook; 5, grow the limit; 6, minor face.

Embodiment

The invention will be further described below in conjunction with accompanying drawing:

A kind of potato machine torsion spring as depicted in figs. 1 and 2, two opposite ends of spring body 1 are extended length respectively, short spring arm 2,3, long spring arm 2 and spring body 1 axial angle is 13 °, short spring arm 3 and spring body 1 axial angle is 55 °, the vertical right angle hook that connects after 13 ° of the long spring arm 2 terminal outwards bendings, long spring arm 2 terminal distances to the axle center are 30.3mm, described right angle hook is combined by orthogonal long limit 5 and minor face 6, the right angle hook top is 37.8mm to the distance in axle center, the length on long limit 5 is 6.0mm, the length of minor face 6 is 5.0mm, the length of short spring arm 3 is 10.0mm, short spring arm 3 tip forward are bent into arc hook 7, it is 14mm to the distance in axle center that arc is linked up with 7 tops, during use spring body 1 is enclosed within on the lower shaft of potato machine knife rest alive, arc hook 7 hangs on the framework of potato machine swivel base, right angle hook 4 hangs over the hanging hole of knife rest alive from the knife rest back side of living, be stuck on the potato machine swivel base at following knife rest alive of twisting force, be pulled outwardly knife rest alive, can drive long spring arm 2 and rotate around the lower shaft of the knife rest of living, kinetic energy is converted into potential energy, removes external force, potential energy is converted into the kinetic energy of resilience, drives the knife rest of living and resets.

Claims
