Description

The bent axle knife rest

Technical field

The utility model relates to a kind of bent axle knife rest of simple in structure, stable work in work, belongs to the crankshaft component assembly and makes the field.

Background technology

Existing bent axle knife rest on structural design, the one, complex structure, the manufacturing cost height, the 2nd, cooperate not science between the lining of bent axle and the alignment pin, cause its service behaviour not good.

Summary of the invention

Purpose of design: avoid the weak point in the background technology, design a kind of bent axle knife rest of simple in structure, stable work in work.

Design: in order to realize above-mentioned purpose of design.1, knife rest alignment pin one end is the design of flange arrangement, is one of technical characterictic of the present utility model.The purpose of doing like this is: the edge of flange can either form clamping with the end face of bent axle alignment pin and cooperate, and is convenient to device again.2,, be two of technical characterictic of the present utility model in the design of alignment pin end face groove.The purpose of doing like this is: the working (machining) efficiency height, but adopt both time processing shapings of drilling machine, be convenient to the installation of spring again, low cost of manufacture.

Technical scheme: a kind of bent axle knife rest, lining are enclosed within on the knife rest alignment pin and knife rest alignment pin one end is flange-like, and flange center has groove, and spring is positioned at groove by pad.

The utility model is compared with background technology, and the one, simple in structure, low cost of manufacture; The 2nd, cooperate science, stable work in work between the lining of bent axle and the alignment pin.

Description of drawings

Fig. 1 is the structural representation of bent axle knife rest.

The specific embodiment

Embodiment 1: with reference to accompanying drawing 1.A kind of bent axle knife rest, lining 2 are enclosed within on the knife rest alignment pin 1 and knife rest alignment pin 1 one ends are flange-like, and flange center has groove, and this groove is used for built-in spring 4.Bottom and bottom portion of groove in order to ensure spring form good stress surface, are equipped with pad 3 in the bottom of groove, and spring 4 is positioned at groove by pad 3.

What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.

Claims (1)

1. bent axle knife rest, it is characterized in that: lining is enclosed within on the knife rest alignment pin and knife rest alignment pin one end is flange-like, and flange center has groove, and spring is positioned at groove by pad.
