Abstract

The utility model relates to a double -end lathe tool, including cutter arbor, tool bit, the tool bit constitutes by hard turning tool bit, ordinary tool bit, the turning tool bit that should manage to do sth. With difficulty, ordinary tool bit are fixed in on the cutter arbor, the head end of hard turning tool bit, ordinary tool bit be in same water flat line on, and in car processing, hard turning tool bit is located the place ahead of ordinary tool bit, the beneficial effects of the utility model are that: on installing same cutter arbor with the tool bit of two kinds of different materials, when guaranteeing the machining precision, accomplishes the size of two differences of a clamping processing, reduction equipment, personnel's input reduces the energy resource consumption, reduces the transport and the clamping of part, improves production efficiency, shortens production cycle, and it is stable to improve product quality.

Description

Lathe tool with two head

Technical field

This utility model belongs to Vehicle Processing lathe tool technical field, more particularly to a kind of is applied to the double of two kinds of cylindrical Vehicle Processings Knife turning tool.

Background technology

Ford model splined shaft smart car is related to two kinds of cylindrical Vehicle Processings, and a kind of is the hard car 3 of bearing guard, another kind of for big end Outer circle finish turning 4, the hardness at two kinds of Vehicle Processing positions are different, need to be processed using the lathe tool of different materials, and bearing guard Dimensional accuracy is higher, only the machining accuracy of 0.011mm, if by the way of swivelling tool-holder, it is complete with two knife clamped one times Into Vehicle Processing, as knife rest has gap, poor dimensional stability easily makes part cause to scrap because of size fluctuation, so only By two lathe process, the two are cylindrical.

There is following defect in which：1st, using two chassis beds, energy resource consumption is big, and floor space is big, and occupied fund is more.2nd, use Two lathe process, need clamping twice, low production efficiency, high labor intensive.3rd, using two lathe process, two behaviour are needed Make personnel, cost of labor is high.4th, production process needs to carry between two chassis beds, and part easily collides with, and the production cycle is also long.5th, two There is error in secondary clamping, two cylindrical concentricitys.

The content of the invention

The purpose of this utility model is to overcome the shortcomings of that prior art is present, and provides a kind of Lathe tool with two head, can be subtracted A few chassis bed, reduction clamped one time, part of reduction are carried, reduce by an operator employee, improve part after Vehicle Processing Axiality, improve product quality.

The purpose of this utility model by following technical solution completing, including knife bar, cutter head, described cutter head by Hard lathe tool, common cutter head composition, the hard lathe tool, common cutter head are fixed on knife bar；Described hard lathe tool, common cutter head Head end in the same horizontal line, and in Vehicle Processing, hard lathe tool is located at the front of common cutter head.

Preferably, the structure of described knife bar is L-type, cutter head is installed on the quarter butt of the knife bar, stock is in Vehicle Processing It is arranged on knife rest in journey.

Preferably, hard car ceramics point of a knife is fixed with described hard lathe tool, on common cutter head, ordinary rigid is fixed with Alloy point of a knife.

The beneficial effects of the utility model are：The cutter head of two kinds of different materials is installed on same knife bar, is being ensured While machining accuracy, complete clamped one time and process two different sizes, reduce equipment, the input of personnel, reduce the energy and disappear Consumption, reduces carrying and the clamping of part, and improve production efficiency shortens the production cycle, improves product quality stability.

Description of the drawings

Fig. 1 is Lathe tool with two head structural representation of the present utility model.

Fig. 2 is the structural representation of Lathe tool with two head bearing shelves of the present utility model.

Fig. 3 is the cylindrical structural representation in the big end of Lathe tool with two head car of the present utility model.

Label in accompanying drawing is respectively：1st, knife bar；2nd, cutter head；3rd, bearing guard；4th, hold greatly cylindrical；11st, quarter butt；12nd, stock； 21st, hard lathe tool；22nd, common cutter head.

Specific embodiment

Detailed introduction is done to this utility model below in conjunction with accompanying drawing：As shown in Figure 1, this utility model includes knife bar 1st, cutter head 2, described cutter head 2 are made up of hard lathe tool 21, common cutter head 22, and the hard lathe tool 21, common cutter head 22 are fixed on On knife bar 1；Described hard lathe tool 21, the head end of common cutter head 22 in same horizontal line, and in Vehicle Processing, hard lathe tool 21 fronts for being located at common cutter head 22.

The structure of described knife bar 1 is L-type, and cutter head 2 is installed on the quarter butt 11 of the knife bar 1, and stock 12 is in Vehicle Processing process In be arranged on knife rest on.

Hard car ceramics point of a knife is fixed with described hard lathe tool 21, ordinary rigid alloy knife on common cutter head 22, is fixed with Point.

Using method of the present utility model is：As shown in accompanying drawing 2,3, on knife rest, then the stock 12 of knife bar 1 is arranged on First with the bearing guard 3 of 21 car splined shaft of hard lathe tool, after car is complete, by the end greatly cylindrical 4 of 22 car splined shaft of common cutter head.It is logical Numerical control programming is crossed, the processing of two step shelves is once realized；Reduce lathe and put into 150,000 yuan, reduce 4 squares of face rice of production site, Reduce by an operator, the input of robot when reducing automated production can save more than 400,000 yuan of production cost.

This utility model is not limited to above-mentioned embodiment, no matter constitute in its shape or material making any change, all It is, using structure design provided by the utility model, to be all a kind of deformation of the present utility model, be considered as new in this practicality Within type protection domain.
