Description
Technical field
The utility model relates to the technical field of milling machine, the especially a kind of milling machine rapid changing knife device that can change cutter fast.
Background technology
Most plain-milling machine or cutters on the drilling machine that use all adopt connecting rod and milling fixture screw top ways of connecting to lock on the market, owing to need to twist many circle screw threads, could pin milling fixture; So the set-up time is long; And when tightening the top nut, needing a hand threaded together, the another hand rest is lived milling fixture; Because milling machine has certain height, the workman changes relatively difficulty of cutter.
The size in milling fixture screw top hole is from multiple standards such as M8 to M24 series, so when the actual installation milling fixture, need many and the corresponding connecting rod in milling fixture screw top hole; And connecting rod generally has only one in milling machine accessory, produces for convenient, and the milling machine user need make these nonstandard connecting rods usually; When mounted; Because connecting rod is longer, tool changing is wasted time and energy very much like this, and the general plain-milling machine replacing cutter time is about 20～30 minutes.
The utility model content
The technical problem that the utility model will solve is: overcome the deficiency in the prior art, a kind of milling machine rapid changing knife device is provided.
The utility model solves the technical scheme that its technical problem adopted: a kind of milling machine rapid changing knife device; Comprise milling fixture, connecting rod and the locking nut that connecting rod is fixing; The top of described milling fixture is provided with the jig that can insert connecting rod, on the end of connecting rod insertion jig, has through hole radially, is inserted with kelly in the through hole; Jig has clamping section and the connector that is connected milling fixture, has the rotatable radial slot that snaps in kelly on the clamping section.
Have the gathering sill that inserts connecting rod on the described clamping section inwall.
The outside of described locking nut is fixed with two pin rods that make things convenient for the rotational lock nut that are oppositely arranged.
Described connector is threaded with milling fixture.
The beneficial effect of the utility model is: the utility model is simple in structure; Easy for installation, quick, need not twist many circle screw threads, and only need a connecting rod just to be suitable for the various series of the bolt of all milling fixtures; The locking nut use that matches with open washer; As long as rotational lock nut 1/2 to 1 circle screw thread just can be locked milling fixture, tool change time only needs 1-2min.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the installation diagram of the utility model.
Fig. 3 is the structural representation of the utility model jig.
Among the figure: 1. milling fixture, 2. connecting rod, 21. through holes, 22. kellies, 3. locking nut, 31. pin rods, 4. jig, 41. clamping sections, 411. radial slots, 42. connectors.
The specific embodiment
Combine accompanying drawing and preferred embodiment that the utility model is further described now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Like Fig. 1, Fig. 2 and a kind of milling machine rapid changing knife device shown in Figure 3; Comprise milling fixture 1, connecting rod 2 and the locking nut 3 that connecting rod 2 is fixed, the top of milling fixture 1 is provided with the jig 4 that can insert connecting rod 2, and an end of connecting rod 2 is a screw thread; So that the locking of locking nut 3; Its side of being provided with, top tenon, connecting rod 2 insert the through hole 21 that has circle radially on the end of jigs 4, are inserted with kelly 22 in the through hole 21; The connector 42 that jig 4 has clamping section 41 and is threaded with milling fixture 1 has the rotatable radial slot 411 that snaps in kelly 22 on the clamping section 41.
Have the gathering sill that inserts connecting rod 2 on the clamping section 41; The outside of locking nut 3 is fixed with two pin rods that make things convenient for rotational lock nut 3 that are oppositely arranged; Can make things convenient for rotational lock nut 3, pin rod 31 can take off, can convenient wrench rotational lock nut 3.
Installation method is:
1, jig 4 screws in the milling fixture 1, promptly selects suitable jig 4 and is spun on the milling fixture 1 through the body 42 that is threaded, because jig 4 can be designed to standard series; In a single day as the annex of plain-milling machine or milling fixture,, generally just no longer spun down so screw on; During tool changing, take off milling fixture 1 and jig 4 simultaneously, both are assembled together when depositing; Use next time, changes simultaneously.
2, connecting rod 2 is connected with jig 4: earlier kelly 22 is fixed in the through hole 21 of connecting rod 2; Then connecting rod 2 is inserted clamping section 41; Kelly 22 inserts in the radial slot 411; Utilize the square tenon at connecting rod 2 tops to clockwise rotate connecting rod 2, make the two ends of kelly 22 be stuck in the left clamping section of clamping section 41, right clamping section place.
3, locking: open washer is inserted connecting rod 2, and the pin rod 31 at trip lock jack panel 3 tops promotes locking connecting rod 2, makes it and jig 4 lockings, thereby reaches the purpose of locking milling fixture 1.
Cutter replacing method is:
1, unclamp: the pin rod 31 at trip lock jack panel 3 tops, connecting rod 2 and connection jig 4 are unclamped, take out open washer.
2, separate: rap the square tenon at connecting rod 2 tops, in jig 4, make milling fixture 1 conical surface leave machine tool chief axis through connecting rod 2 the other end active forces.
3, take out: rotate counterclockwise the square tenon at connecting rod 2 tops, make kelly 22 arrive the exit of clamping section 41, take out milling fixture 1.
The utility model can be applied to processing type apparatuses such as milling machine, lathe, drilling machine, and is widely applicable.
The foregoing description is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage that is familiar with this technology can understand the content of the utility model and implements; Can not limit the protection domain of the utility model with this; All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the utility model.
