Abstract

The utility model relates to the technical field of mechanical manufacturing, in particular to a knife rest for disassembly, which is used for disassembling a mohs knife handle; the knife rest for disassembly is composed of a base, a knife rest and a supporting frame connecting the base and the knife rest which form a hollow main body, combined type knife holes with different size are arranged in the center of the knife rest, the bore diameter of the knife hole at the outer side is more than that of the knife hole at the inner side, and a through hole is arranged in the middle of the base. The knife rest for disassembly can well solve the technical problem that disassembly of cutters is difficult, the cutter is clamped in the knife hole, and the cutter is ejected out from the knife handle below the knife hole with a lifting jack, thereby being convenient and practical.

Description

Tear knife rest open

Technical field

The utility model relates to the Machining Technology field, relates in particular to a kind of knife rest of tearing open that is used to dismantle the Mohs handle of a knife.

Background technology

Processing adopts cutter that its surface is cut to surface of the work in the Machining Technology field, if but generally the Mohs cutter is after big surplus cutting or long-time cutting, cutter hub meeting temperature distortion, and conventional method can't disassemble cutter hub from handle of a knife.

The utility model content

It is a kind of that the utility model provides, to solve this technical problem of cutter dismounting difficulty.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of knife rest of tearing open, the main body of forming a hollow by the bracing frame of base, knife rest and connection base and knife rest, knife rest central authorities offer the box-like tool bore of size groups, the aperture of outside tool bore is greater than the aperture of inboard tool bore, and base central authorities offer through hole.

The utility model can solve this technical problem of cutter dismounting difficulty, and cutter is stuck in the tool bore, with jack cutter is ejected from handle of a knife below, and is convenient and practical.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Wherein: 1, base, 2, knife rest, 3, bracing frame, 4, tool bore, 5, through hole, 6, cutter hub, 7, handle of a knife.

The specific embodiment

With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

As shown in Figure 1, a kind of knife rest of tearing open is formed the main body of a hollow by base 1, knife rest 2 and the bracing frame 3 that connects base 1 and knife rest 2, and knife rest 2 central authorities offer the box-like tool bore 4 of size groups, the aperture of outside tool bore is greater than the aperture of inboard tool bore, and base 1 central authorities offer through hole 5.

Mohs cutter hub 6 oppositely stretches in the tool bore 4 on the knife rest 2, be stuck on the step of tool bore 4, remaining part stretches into handle of a knife 7, be connected with handle of a knife, can process operation, after finishing using, stretch into the through hole of process base with jack, the interior Mohs cutter hub is ejected of through hole that enters handle of a knife then torn knife rest open, so cutter hub can be disassembled from handle of a knife, uses very convenient.

Claims

1, a kind of knife rest of tearing open, the main body of forming a hollow by the bracing frame (3) of base (1), knife rest (2) and connection base (1) and knife rest (2), it is characterized in that: described knife rest (2) central authorities offer the box-like tool bore of size groups (4), the aperture of outside tool bore is greater than the aperture of inboard tool bore, and base (1) central authorities offer through hole (5).
