Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, the utility model provides a milling cutter placing rack, which comprises a central column 1, a unit ring 2 and a bottom ring 3; the bottom ring 3 is clamped on the side wall of the bottom end of the central column 1, and a plurality of unit rings 2 are arranged; the unit rings 2 and the bottom ring 3, and any two connected unit rings 2 are connected through the same concave-convex matching structure 4.

With reference to fig. 3, the concave-convex matching structure 4 includes four chucks 41 disposed at the top end, the bottom end, or the top end of the bottom ring 3 of the unit ring 2, the four chucks 41 are disposed at equal intervals, and a slot 42 having the same size as the chuck 41 is disposed between any two chucks 41, that is, the chucks 41 and the slot 42 are disposed in a staggered manner.

The clamping head 41 and the clamping groove 42 on the unit ring 2 with the structure can be clamped on other unit rings 2 or the bottom ring 3 respectively, so that the assembled unit ring 2 cannot rotate radially relative to other unit rings 2 or the bottom ring 3.

With reference to fig. 1 and 2, the milling cutter placing frame further comprises a placing disc 5, the placing disc 5 is circular, a plurality of placing pins 51 extending upwards are arranged on the top surface of the placing disc 5, which is close to the peripheral wall, and holes for placing milling cutters are arranged on the placing pins 51; a round hole is also formed in the center of the placing disc 5, the placing disc 5 can be sleeved on the central columns 1 through the round hole, and the diameter of the round hole is larger than the diameter between the central columns 1 and smaller than the diameter of the outer wall of the unit ring 2;

the placing disc 5 is provided with four notches 52 matched with the clamping heads 41 along the circumference of the circular hole, a plurality of plugs 53 matched with the clamping grooves 42 are formed between any two notches 52, and the plugs 53 and the notches 52 are arranged in a staggered mode; the plug 53 can be inserted between the chuck 41 of the unit ring 2 and the chuck 42 of the other unit ring 2 so that the placing tray 5 is not moved relative to the unit ring 2 or the bottom ring 3 after being installed.

Referring to fig. 3, any one of the plugs 53 is in the form of a hollow dovetail, and an inwardly concave elastic groove 531 is formed at the top of the dovetail, and the dovetail plug 53 is made of an elastic steel sheet welded to a circular hole.

Before the dovetail plug 53 is inserted into the clamping groove 42 of the unit ring 2, the two ends of the dovetail are firstly extruded to shrink the elastic groove 531, then the extruded dovetail plug 53 is inserted into the clamping groove 42, at this time, the elastic groove 531 expands towards the two ends, the fixing effect of the plug 53 on the clamping groove 42 can be enhanced, and therefore the firmness of the placing disc 5 on the unit ring 2 can be enhanced.

In the present embodiment, three unit rings 2 are sandwiched between any two of the placing trays 5; the number of the unit rings 2 can be changed, the distance between the two placing discs 5 can be changed, and the milling cutter placing frame can be adapted to milling cutters of various models.

Referring to fig. 4, the outer wall surface of the outer wall of the center pillar 1, which is wrapped by the bottom ring 3, is integrally formed with a strip groove 11 arranged along the axial direction of the center pillar 1 and a plurality of transverse grooves 12 arranged along the radial direction of the center pillar 1; the two sides of the strip groove 11 are both provided with transverse grooves 12, the transverse grooves 12 on each side are arranged at equal intervals, the transverse strips on the two sides are arranged in a staggered manner, and one end of each transverse groove 12 is communicated with the strip groove 11; the inner wall of the bottom ring 3 is provided with a clamping block 31 which can be assembled in the strip groove 11 or the transverse groove 12.

After changing the interval of placing dish 5, place the whole central part that may not be in the carburizing furnace of dish 5, so need make unit ring 2 and place the same rebound of dish 5 with bottom ring 3 rebound, move in-process fixture block 31 and can follow a groove 11 rebound, then select the cross slot 12 of suitable position, move fixture block 31 in the cross slot 12, thereby can be to placing the whole earlier upwards removal to center pillar 1 of dish 5, make and place the whole body that can more be close the carburizing furnace center of dish 5.

In order to enhance the stability of the placing plate 5, one end of the transverse groove 12 far away from the strip groove 11 is arranged downwards, so that the bottom ring 3 can not rotate on the central column 1 in the radial direction; in order to smoothly move the latch 31 in the bar groove 11 and the transverse groove 12, the latch 31 is formed in a cylindrical shape because the cylindrical structure does not provide an edge on the sidewall of the latch 31.

The utility model discloses an implement the principle and do: firstly, a placing disc 5 is placed at the top end of a bottom ring 3, then a unit ring 2 is sleeved on a middle column 1, and the placing disc 5 is clamped between the bottom ring 3 and the unit ring 2; selecting a proper number of unit rings 2 according to the type of the milling cutter, sleeving the unit rings on the central column 1, fixing the unit rings with each other, and sleeving a placing disc 5 on the central column 1, so that the distance between the two placing discs 5 is matched with the type of the milling cutter; a plurality of placing discs 5 can be arranged in turn;

after placing dish 5 and being fixed in on center pillar 1, place the whole carburizing furnace middle part that may not be arranged in of dish 5, the height of bottom ring 3 is adjusted to the accessible here, promotes unit ring 2 and places dish 5, makes and places the whole height control that can go on of dish 5 on center pillar 1, until placing the whole most approximate carburizing furnace middle part of dish 5.

The embodiment of this embodiment is the preferred embodiment of the present invention, not limiting in proper order the utility model discloses a protection scope, the event: all equivalent changes made according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
