Abstract

The utility model relates to a milling flat cutter clamp which belongs to the technical field of milling machine parts. The milling flat cutter clamp comprises a prismatical cutter handle; the lower end of the prismatical cutter handle is connected with a cutter head; a square fixed hole with an opening on the lower end is arranged on the cutter head; the upper end of a cutting tool is inserted into the square fixed hole of the cutter head; the cutter head is provided with two locking screw holes; the inner ends of the two locking screw holes are respectively arranged on the two hole walls of the square fixed hole; two locking screws are respectively matched with the locking screw holes; the ends of the locking screws respectively contact with the surface of the cutting tool. The milling flat cutter clamp has the advantages of quite low cost, good surface roughness of milling and high cutting speed, and solves the problems of quite high cost, low cutting speed, poor surface roughness after product processing and the like of the prior straight-handle key way milling cutter.

Description

The milling flat tool holder

Technical field

The utility model relates to a kind of milling flat tool holder, belongs to the technical field of milling machine kit.

Technical background

Mill a kind of usual way that is processed as plane processing, in the prior art, the straight shank keyway mills material generally adopts whole high-speed steel to make, and cost is higher, while cutting speed lower (approximately 22m/min), and the surface roughness after the product processing is poor.

Summary of the invention

The utility model purpose is to provide a kind of cost lower, the plane roughness of milling processing is better, the milling flat anchor clamps that cutting speed is higher, and the cost that has solved existing straight shank keyway mills existence is higher, cutting speed is lower simultaneously, the problems such as surface roughness difference after the product processing.

Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises the column handle of a knife, described column handle of a knife lower end is connected with cutterhead, described cutterhead forms the square fixing hole of lower ending opening, dolly cutter upper end is inserted in the square fixing hole of cutterhead, cutterhead is provided with two screw hole, the inner of described two screw hole lays respectively on two hole walls of square fixing hole, two lock screw cooperate with screw hole respectively, and the end of two lock screw contacts with the surface of little lathe tool respectively.The utility model adopts the dolly cutter of relative low price as cutting edge, has reduced the cost of charp tool.Because the material of cutter head is a carbide alloy, improved greatly cutting speed (90-150m/min), after the product processing satisfied surface roughness arranged.

As preferably, the axis of described two screw hole is vertical mutually, thereby but the square face of ejection dolly cutter upper end and two adjacent inner hole walls of the square fixing hole of cutterhead fit tightly, little lathe tool and cutterhead are fixed together reliably.

As preferably, be threaded between described column handle of a knife and the cutterhead, thereby be convenient to loading and unloading between column handle of a knife and the cutterhead.

Therefore, it is lower to the utlity model has cost, and the plane roughness of milling processing is better, and cutting speed is than characteristics such as height.

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is a kind of structural representation of cutterhead;

Fig. 3 is the A-A view of Fig. 2.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment 1: as Fig. 1, Fig. 2 and shown in Figure 3, the lower end of column handle of a knife 1 is threaded with the upper end of cutterhead 2, cutterhead 2 forms the square fixing hole 3 of lower ending opening, dolly cutter 4 upper ends are inserted in the square fixing hole 3 of cutterhead 2, cutterhead 2 is provided with two screw hole 5, the inner of two screw hole 5 lays respectively on two hole walls of square fixing hole 3, and the axis of two screw hole 5 is vertical mutually; Two lock screw 6 cooperate with screw hole 5 respectively, and the end of two lock screw 6 contacts with the surface of dolly cutter 4 respectively.

Claims

1, a kind of milling flat tool holder, comprise the column handle of a knife, it is characterized in that described column handle of a knife lower end is connected with cutterhead, described cutterhead forms the square fixing hole of lower ending opening, dolly cutter upper end is inserted in the square fixing hole of cutterhead, and cutterhead is provided with two screw hole, and the inner of described two screw hole lays respectively on two hole walls of square fixing hole, two lock screw cooperate with screw hole respectively, and the end of two lock screw contacts with the surface of little lathe tool respectively.
