Abstract

The utility model discloses an knife clamping and loosing device which comprises a knife rest. A hydraulic cylinder is fixedly installed in the knife rest. A piston rod of the hydraulic cylinder is connected with a movable rod used for an upper pipe clamp. Threads are arranged on the movable rod used for the upper pipe clamp. Two nuts are arranged on the threads in a sleeved mode. A reset clamping device is arranged on the movable rod used for the upper pipe clamp. One end, far from the piston rod, of the movable rod used for the upper pipe clamp extends out of the knife rest, and a wedge-shaped block is installed through screws. The inclined plane of the wedge-shaped block is matched with a knife holder. The other face of the wedge-shaped block contacts with a knife body. The knife holder is fixedly installed on the knife rest. The hydraulic cylinder supplies power to the elastic knife so that central control and operation are convenient. A cutter is clamped through the wedge-shaped block, and clamping is reliable. The two nuts are arranged on the movable rod used for the upper pipe clamp. By rotating of the nuts, the degree of tightness of a belleville spring can be adjusted and a clamping force is indirectly adjusted.

Description

A kind of degree of tightness knife system
Technical field
The utility model relates to a kind of machining set-up, relates in particular to a kind of degree of tightness knife system.
Background technology
The machine of cutting is a kind of of lathe, and it adopts hydraulic-driven, and security performance is reliable, and is easy to operate.Cutter is applicable to metal recovery processing factory, abandoned car is disassembled field, metallurgy and foundry industry, the shaped steel of various shapes and various metal material are carried out cold conditions cut off, suppress flange, and Powdered goods, plastics, fiberglass, insulating materials, rubber is compressing.
The cutter hub of cutter is usually longer, need to it be connected with tool rest by a plurality of fixtures, traditional cutter cutter hub is bolted on the tool rest, in the needs laid-up, need one by one bolt to be screwed out cutter hub is write, after maintenance is finished, to screw bolt cutter hub is clamped, because the more loading and unloading of clamping bolt are very inconvenient.
The utility model content
The technical problem that the utility model solves is: a kind of easy-to-dismount degree of tightness knife system is provided, increases work efficiency simultaneously reliably at the assurance clamping.
For reaching this purpose, the utility model by the following technical solutions:
A kind of degree of tightness knife system, comprise knife rest, be installed with hydraulic cylinder in the described knife rest, the piston rod of described hydraulic cylinder connects the upper pipe clamp bar of living, described upper pipe clamp is with being provided with screw thread on the bar of living, sheathed two nuts on the described screw thread, described upper pipe clamp is with being provided with the clamping device that resets on the bar of living, described upper pipe clamp stretches out knife rest with the end of bar away from piston rod of living, and by screw wedge is installed, described wedge inclined-plane matches with tool rest, and another side contacts with cutter hub, and described tool rest is fixedly mounted on the knife rest.
Further, the described clamping device that resets is to be set in the pipe clamp spring of living on doing, and described spring top contacts with nut, and base abuts is in the knife rest upper base surface.
Further, described spring adopts butterfly spring.
Further, described hydraulic cylinder adopts the single-column plug cylinder.
The beneficial effects of the utility model are: adopt hydraulic cylinder to provide power for loose cutter, are convenient to centralized Control, and easy to operate, by wedge clamping cutter, clamping is reliable, with the bar of living two nuts is set at upper pipe clamp, by rotating the tightness that to regulate butterfly spring, Indirect method clamping force.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is degree of tightness knife system structural representation.
Among the figure:
1, knife rest; 2, single plunger hydraulic cylinder; 3, the upper pipe clamp bar of living; 4, nut; 5, butterfly spring; 6, tool rest; 7, cutter hub; 8, wedge.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
As shown in Figure 1, in present embodiment, a kind of degree of tightness knife system described in the utility model, it comprises knife rest 1, be installed with single plunger hydraulic cylinder 2 in the described knife rest 1, the piston rod of described single plunger hydraulic cylinder 2 connects the upper pipe clamp bar 3 of living, described upper pipe clamp is with being provided with screw thread on the bar 3 of living, be provided with in succession two nuts 4 on the described screw thread, described upper pipe clamp passes away from an end of piston rod with piston rod 3 and stretches out knife rest 1 lower surface, be arranged with butterfly spring 5 between described nut 4 and knife rest 1 lower surface, described upper pipe clamp is equipped with wedge 8 with the end end that piston rod 3 stretches out knife rest 1 by screw, described wedge 8 inclined-planes match with tool rest 6, and another side contacts with cutter hub 7, and described tool rest 6 is mounted by means of bolts on the knife rest 1.
Butterfly spring 5 is in compressive state, when needing clamping on tool rest 6, cutter hub 7 make single plunger hydraulic cylinder 2 be in relaxed state, elastic force by butterfly spring 5 promotes nut 4, pipe clamp is moved upward with respect to knife rest 1 with the bar 3 of living drives wedge 8 and move upward cutter hub 7 is clamped, when needs unclamp cutter hub 7 to single plunger hydraulic cylinder 2 fuel feeding its piston rod is stretched out promote wedge 8 outwards motion unclamp cutter hub 7.
Adopt single plunger 2 hydraulic cylinders to provide power for loose cutter, be convenient to centralized Control, easy to operate, by wedge 8 clamping cutters, clamping is reliable, with the bar 3 of living two nuts 4 is set at upper pipe clamp, by rotating the tightness that to regulate butterfly spring 5, Indirect method clamping force.
What need statement is; the above-mentioned specific embodiment only is preferred embodiment of the present utility model and institute's application technology principle; in technical scope disclosed in the utility model; the variation that any those skilled in the art of being familiar with expected easily or replacement all should be encompassed in the protection domain of the present utility model.
