Abstract

An experimental device for measuring the temperature field of a cutting tool. The temperature measuring device with a thermocouple and the cutting tool used in the cutting process are clamped on the tool holder of the machine tool. To measure the cutting temperature at any point on the side of the cutting tool, as long as the Turn the nuts of the vertical scale and the horizontal scale to move the thermocouple contacts to the desired positions. The utility model has the advantages of small volume, simple structure, good manufacturability, low cost and convenient use, and is suitable for application in scientific research units, colleges, scientific research and teaching experiments.

Description

Experiment device for testing temp. field of cutting tool

The utility model belongs to the device of using thermocouple measuring temperature.

Heat in metal cutting is one of important physical phenomena in the working angles, cutting temperature can change the friction factor on the cutter rake face, change the character that workpiece material adds man-hour, influence the machined surface quality, the temperature field during cutting has a significant impact the abrading section of cutter.Because the complicacy of working angles, theoretical analytical method is found the solution the cutting temperature field and still is restricted, and not only result of calculation will be come the verification correction by experimental result, and the many parameters in calculating will be determined by experiment.The temperature field of cutter is still the main method in the present Study of Cutting when therefore, utilizing laboratory facilities to measure cutting.

The utility model is that the cutting tool used in thermocouple temperature measuring apparatus and the working angles that will have through particular design combines as a whole, can install easily, clamping on lathe cutter saddle, it can be used for the measurement in the temperature field of the flank of tool in the general two dimension cutting.

Description of drawings:

The front elevation of Fig. 1, this experimental provision;

The side view of Fig. 2, this experimental provision;

The vertical view of Fig. 3, this experimental provision.

Provide details of the present utility model below in conjunction with accompanying drawing.As Fig. 1, Fig. 2, shown in Figure 3, this device is made up of tool rest 1, support 2, thermopair 3, pressing plate 4, plunger 5, hollow cylinder 6, cover plate 7, scale 8, spring 9, cross lead screw 10, horizontal rule 11, knurled nut 12, U-lag 13, vertical rule 14, vertical screw mandrel 15, knurled nut 16 etc.Laterally the U-lag 13 of rule 11 1 ends is slidingly matched for 14 one-tenth with vertical rule with the rectangular opening that pressing plate 4 constitutes, vertically screw mandrel 15 1 ends are fixedlyed connected with horizontal rule 11, the other end matches with knurled nut 16 by the aperture in vertical rule 14, when the knurled nut 16 in placing vertical rule 14 rotated, the horizontal rule 11 that combines as a whole with vertical screw mandrel 15 longitudinally rule 14 moved up and down; The plunger 5 big ends of interior dress thermopair 3 are inserted in the hollow cylinder 6, hollow cylinder 6 is slidingly matched for 11 one-tenth with horizontal rule with the rectangular opening that scale 8 constitutes, cross lead screw 10 1 ends are fixedlyed connected with hollow cylinder 6, the other end matches with knurled nut 12 by the aperture in the horizontal rule, when the knurled nut 12 in placing horizontal rule 11 rotates, with the hollow cylinder 6 that cross lead screw 10 combines as a whole will be along horizontal rule 11 move left and right.Place the springs 9 in the hollow cylinder 6 to be pressed in plunger 5 large end faces, the contact of thermopair 3 contacted with the cutting tool side, the vertical rule 14 of whole device mat, support 2, tool rest 1 with the cutting tool clamping on lathe cutter saddle.

In will measuring the coordinate in length and breadth that point of a knife is an initial point on the cutting tool side arbitrarily during the cutting temperature of a bit,, make the contact of thermopair 3 move to the desired position and get final product as long as rotate vertical rule 14, the horizontal knurled nut in the rule 11 respectively.

The utility model volume is little, and is simple in structure, and good manufacturability, cost are low, can combine as a whole with cutting tool, and easily clamping on the knife rest of lathe, easy to use, the measuring position is accurate, is suitable for using in R﹠D institution, institute of college, scientific research and the education experiment.
