Description
Technical field
The utility model is related to desk-top drilling and milling machine field, especially a kind of main axle structure being conveniently replaceable cutter.
Background technology
Traditional milling and drilling machine is mainly by spindle box（Gearbox）, main shaft, axle sleeve, workbench, pedestal, column, planker, connection
The mechanisms such as plate, motor form, and wherein main shaft should rotate in processing, also do axial feed motion.And main shaft is another
One critical function is exactly that cutter is clamped, and traditional drilling and milling machine main shaft is to use pull rod and tight when cutter is clamped（Pull rod lower end
For screw thread, the screw-thread fit with shank end；Upper end mill hexagon is flat, for rotating）.
When replacing cutter, it is necessary to use spanner from main shaft upper end rotating rod so that the screw thread and handle of a knife of pull rod lower end
Screw thread removes cutter after disengaging, then new cutter is inserted into the cavity of main shaft lower end, and then rotating rod makes pull rod again
Lower thread, which screws in handle of a knife screw thread, just may be used.Such substitute mode is comparatively laborious, replaces cutter and quite wastes time.
Utility model content
Purpose of the utility model is to solve traditional drilling and milling machine replacement cutter is cumbersome, it has not been convenient to the problem of, it provides
A kind of main axle structure being conveniently replaceable cutter.
The technical solution that the utility model solves above-mentioned technical problem is as follows：A kind of main axle structure being conveniently replaceable cutter,
Including main shaft, compression bar, spring clip be fixed, compressed spring, the support base up and down of compressed spring, threaded and Latin type handle of a knife, institute
It states spring clamp set upper side and is equipped with several L for the through-hole of entity and center equipped with installation threaded, lower end boring and outside
Type vertical bar shape clamp hook, lower end base diameter are more than upper end, and compressed spring upper support seat upper end both sides are again provided with screw thread
Mounting hole is sold, the main-shaft core is equipped with endoporus, and it is cylindrical cavity and sky to divide upper plenum, hollow cavity and lower cavity, upper plenum
Intracavitary is equipped with compression bar, and hollow cavity is cylindrical cavity and diameter is more than upper plenum, and the hollow cavity both sides are equipped with identical size
Waist type groove, threaded through compressed spring upper support seat, main shaft hollow cavity gain and spring clamp set upper side pin hole by spring
Gripping sleeve is fixed in main shaft hollow cavity, makes spring clip is fixed can be moved up and down in gain, and lower cavity is up-small and down-big cone
Shape cavity and upper end diameter are more than hollow cavity diameter.When replacing handle of a knife, lower moulded rod props up on fastening spring set, compressed spring
Support seat moves down simultaneously, and compressed spring is at compression shape；It simultaneously clamps on spring pocket lower end base and leaves main shaft hollow cavity, clamp hook unclamps
In free state, the fixed interior Latin of script spring clip is released, and the handle of a knife being replaced is fallen naturally, then will be needed replacing again
Handle of a knife stretched into hole by main shaft lower end, the Latin at the top of handle of a knife enter fastening spring set clamp hook in；Then compression bar is unclamped, this
When compressed spring spring back so that compressed spring on support and fastening spring cover return, fastening spring cover lower end clamp hook and handle of a knife
The Latin of handle upper end returns in main shaft hollow cavity together simultaneously, and fastening spring set lower end in tightening shape and has been clamped on cutter at this time
The Latin at end.Be not in stuck problem it is thereby achieved that cutter is convenient for changing.
The utility model proves that effect is ideal, simple and practical through using.

Specific implementation mode
The main axle structure for being conveniently replaceable cutter a kind of to the utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, a kind of main axle structure being conveniently replaceable cutter, including main shaft 1, compression bar 2, spring clip it is fixed 3,
Compressed spring 4, the upper support seat 5 and lower support base 6 of compressed spring 4, threaded 8 and Latin type handle of a knife 7, the spring clip are fixed
3 upper ends are that the through-hole that entity and center are equipped with installation threaded 8, lower end boring and outside are pressed from both sides equipped with several L-type vertical bar shapes
Tight hook 9, the fixed 3 lower end base diameter of spring clip are more than upper end, and 4 upper support seat of the compressed spring, 5 upper end both sides are same
Equipped with 8 mounting hole of threaded, 1 center of the main shaft is equipped with endoporus, divides upper plenum 10, hollow cavity 11 and lower cavity 12, upper plenum
10 is are equipped with compression bar 2 in cylindrical cavity and cavity, hollow cavity 11 is cylindrical cavity and diameter is more than upper plenum 10, in described
11 both sides of cavity are equipped with the waist type groove of identical size, and threaded 8 is through 4 upper support seat 5 of compressed spring, 1 hollow cavity of main shaft, 11 waist
Spring clip fixed 3 is fixed in 1 hollow cavity 11 of main shaft by slot and the pin hole of fixed 3 upper end of spring clip, makes spring clip fixed 3 can be
It is moved up and down in gain, lower cavity 12 is that up-small and down-big conical cavity and upper end diameter are more than 11 diameter of hollow cavity.Work as replacement
When handle of a knife, lower moulded rod 2, fastening spring set 3,4 upper support seat 5 of compressed spring move down simultaneously, and compressed spring 4 is at compression shape；Together
When fastening spring cover 3 lower end bases and leave 1 hollow cavity 11 of main shaft, it is in free state, script spring clip fixed 3 that clamp hook 9, which unclamps,
Interior Latin is released, and the handle of a knife being replaced is fallen naturally, and the handle of a knife needed replacing is then stretched into hole by 1 lower end of main shaft again
Interior, the Latin at the top of handle of a knife enters fastening spring and covers in 3 clamp hooks 9；Then compression bar 2 is unclamped, compressed spring 4, which is sprung back, at this time makes
Support 5 and fastening spring cover 3 returns in compressed spring 4, and fastening spring covers the Latin of the clamp hook 9 and handle of a knife handle upper end of 3 lower ends
It returns to together in 1 hollow cavity 11 of main shaft simultaneously, fastening spring covers 3 lower ends in tightening shape and clamped the drawing of cutter upper end at this time
Fourth.Be not in stuck problem it is thereby achieved that cutter is convenient for changing.
The preferred embodiment that these are only the utility model, is not intended to limit the utility model, all in the utility model
Spirit and principle within, any modification, equivalent replacement, improvement and so on should be included in the protection model of the utility model
Within enclosing.
