Abstract
The utility model discloses a spindle knife loosening mechanism which comprises a gas-liquid supercharging cylinder, a pressing rod, disk springs, a pressing sleeve, marbles and a pulling nail. When knife loosening is required, a knife loosening button at the front end of a spindle is pressed, the gas-liquid supercharging cylinder is pressed downwards to provide pressure, the pressing rod in the spindle is pressed downwards, the disk springs are extended, the pressing sleeve is supported open downwards, the marbles slide, the pulling nail mounted at the rear end of a knife handle slides out of a mounting port, and the knife loosening is accomplished. The spindle knife loosening mechanism has the advantages that knife loosening hydraulic transmission is accomplished by extending the springs, so that the spindle is prevented from bearing an axial force effectively, the service life of the spindle is prolonged, the whole mechanism is simple in structure, and the manufacturing cost is lowered.
Description
Technical field
The utility model relates to loose cutter, the broaching tool technical field of milling machine, relates in particular to a kind of main shaft knife loosening mechanism.
Background technology
At present the cutter-removing mechanism on milling machine generally comprises casing and is arranged on the main shaft in the housing seat hole and is arranged on the interior push broach bar of main shaft, main shaft knife loosening mechanism promotes to complete loose cutter by airdraulic actuator transmission catch bar, the problem that exists is can strain also when reaching broaching tool to guarantee that simultaneously loose cutter is easily easy, often internal structure is very complicated, apparatus parts is various, and this just causes easily going wrong, and makes the main shaft precision stability low, and cost is high, and corrupted is repaired and is difficult for.
The utility model content
For solving the loaded down with trivial details technical problem of above-mentioned device for loosening cutter on main shaft member, the technical scheme that the utility model is taked is:
A kind of main shaft knife loosening mechanism, comprise pneumohydraulic pressure-cylinder, main shaft, milling cutter, it is characterized in that, also comprise depression bar, disk spring, gland, hoodle, blind rivet, pneumohydraulic pressure-cylinder is positioned at main shaft tail, vertically be installed with 2 disk springs in main shaft side by side, between 2 disk springs, depression bar be housed, be connected with gland under disk spring, hoodle is placed in below gland, blind rivet is housed on milling handle, and described disk spring keeps 1000kg pulling force tension gland when broaching tool, drives hoodle chucking blind rivet.Need Song Daoshi to press front-end of spindle pine cutter button, pneumohydraulic pressure-cylinder presses to down provides pressure, and in main shaft, depression bar is to pressing down, and disk spring rises to be opened, and gland struts downwards, and hoodle slips off, and the blind rivet that is contained in the handle of a knife tail end skids off installing port, and loose cutter is completed.
The utility model advantage is, loose cutter hydraulic drive is risen by spring and completes, and has effectively avoided main shaft to bear axial force, has promoted Main Shaft Service Life, and whole apparatus structure is simple, reduces manufacturing cost.
Description of drawings
Fig. 1 is a kind of main shaft knife loosening structural scheme of mechanism.
Fig. 2 is a kind of main spindle broach structural scheme of mechanism.
Fig. 3 is the pneumohydraulic pressure-cylinder schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details,
As a kind of in Fig. 1 main shaft knife loosening mechanism comprises pneumohydraulic pressure-cylinder 1, depression bar 3, disk spring 4, gland 5, hoodle 6, blind rivet 7, and described disk spring keeps 1000kg pulling force tension gland when broaching tool, drives the hoodle chucking and is installed on blind rivet 7 on handle of a knife 8.
Press lower main axis 2 front ends pine cutter buttons when needing loose cutter, pneumohydraulic pressure-cylinder 1 presses to down provides pressure, and the interior depression bar 3 of main shaft 2 is to pressing down, and 4 liters of disk springs are opened, and gland 5 struts downwards, and hoodle 6 slips off, and the blind rivet 7 that is contained in handle of a knife 8 tail ends skids off installing port, and loose cutter is completed.
Pine should be noted during cutter, first live handle of a knife 8 again by loose cutter button with hand rest.
Room dress cutter should be noted, must first press loose cutter button, after loading onto cutter, just can unclamp loose cutter button.
Though abovely described part specific embodiment of the present utility model.Should be appreciated that those of ordinary skill in the art need not creative work and just can make many modifications and variations according to design of the present utility model.Therefore, all technical staff in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in the determined protection domain by claims.
Claims (2)
