A kind of heat expansion cutter Rapid Combination device
Technical field
The utility model relates to a kind of cutter composite set, relates in particular to a kind of heat expansion cutter Rapid Combination device.
Background technology
In original connecting rod production and processing, need carry out counterbore processing for coupling nut place, the connecting rod back side, owing to interfered by gonnecting rod body, its cutter head need be lengthened to drill chuck and avoid length that drilling rod is interfered, its cutter head needs to be lengthened to the 100-150 millimeter at least, to the counterbore aperture cutter head of 10 millimeter only, lengthens its intensity of back and obviously reduces, adopt drill bushing also can bring huge waste because the cutter head mill just can't use after being short to 20 millimeters for small rod.
The utility model content
The purpose of this utility model provides a kind of heat expansion cutter Rapid Combination device with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises the heating head column, the heating head support, the cooling tracheae, heating generator, the knife bar seat, the workpiece base, controller and air-cooler, described heating head column and described knife bar seat all are installed on the described workpiece base, described heating generator is connected with described heating head column by described heating head support, described heating head support can be mobile at described heating head column, described knife bar seat be positioned at described heating generator under, one end of described cooling tracheae is connected with described air-cooler, the other end places in the described heating generator, the signal output part of described controller is connected with the signal input part of described air-cooler, and the signal output part of described heating generator is connected with the signal input part of described controller.
The beneficial effects of the utility model are:
The principle that the utility model utilizes metal to expand with heat and contract with cold makes the knife bar hole realize making up with the quick replacing of cutter head to be welded; The utility model effectively improves the intensity of drilling tool, has saved manufacturing cost.
Description of drawings
Fig. 1 is the structural representation of a kind of heat expansion cutter Rapid Combination device described in the utility model;
Among the figure: 1-heating head column, 2-heating head support, 3-cooling tracheae, 4-cutter head to be welded, 5-heating generator, 6-knife bar, 7-workpiece base, 8-controller, 9-air-cooler, 10-knife bar seat.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1: the utility model comprises heating head column 1, heating head support 2, cooling tracheae 3, heating generator 5, knife bar seat 10, workpiece base 7, controller 8 and air-cooler 9, heating head column 1 and knife bar seat 10 all are installed on the workpiece base 7, heating generator 5 is connected with heating head column 1 by heating head support 2, heating head support 2 can be mobile at heating head column 1, knife bar seat 10 be positioned at heating generator 5 under, one end of cooling tracheae 3 is connected with air-cooler 9, the other end places in the heating generator 5, the signal output part of controller 8 is connected with the signal input part of air-cooler 9, and the signal output part of heating generator 5 is connected with the signal input part of controller 8.
Operation principle of the present utility model is as follows:
As shown in Figure 1, the heating head column of installing at workpiece base 71 can heat the drilling rod of different length, at knife bar seat 10 knife bar 6 is installed, the head of heating generator 5 is adjusted to the position that needs heating, connect power supply to heating generator 5 energisings, make knife bar 6 installing hole expanded by heating, cutter head 4 to be welded is inserted in knife bar 6 holes, open and force the cooling air switch, air-cooler 9 work, pressure cold wind enters from cooling tracheae 3 lowers the temperature to the knife bar 6 of expanded by heating, and the Rapid Combination of finishing cutter head 4 to be welded and knife bar 6 is shunk in knife bar 6 holes with cooling.
