Description

A kind of thread machining device for carbon-carbon composites
Technical field
The utility model is related to a kind of thread machining devices for carbon-carbon composites, belong to screw thread process field.
Background technology
C/C composite materials are (referred to as " CFC ") carbon fiber reinforced carbon basis materials, are a kind of quasi- three-dimensional structures, in vacuum Or under protective atmosphere, temperature in use is up to 2700 DEG C, has high-purity, high mechanical properties (high intensity, high-modulus), thermal expansion system The low, heat shock resistances of number, the advantages that antifatigue, density is low, dimensional stability is high, corrosion-resistant, electric good conductor, what is thus produced is tight Firmware (bolt, nut etc.) is widely used in various high-temperature services (list, polycrystalline furnace in such as high temperature graphitization stove, photovoltaic industry Deng).But CFC bolts, nut production process in, particularly bolt processing, existing frequently-used processing method, first, screw die Processing, second is that Lathe turning tool is processed, third, whirling mill, since CFC matrixes are a kind of quasi- three-dimensional structures of Carbon fibe lamination pin thorn, Its hardness is high, has brittleness, when being processed with these three methods, the form of thread processed is poor, and there are hypodontia snaggletooth phenomenons, influence to connect Intensity is connect, larger, increase processing cost and processing efficiency are in addition worn to process tool.
Utility model content
The utility model provides a kind of for charcoal charcoal composite wood to solve the problems, such as carbon-carbon composites in screw thread process The thread machining device of material.
The technical solution that the utility model solves above-mentioned technical problem is as follows:A kind of screw thread for carbon-carbon composites adds Frock is put, and is characterized in that, including workbench, the spindle stock mounted on workbench one end, and spindle stock The top installation shielded closure mechanism of the chuck in front, angle grinder are mounted on by angle grinder fixed seat on sawtooth slideway, and sawtooth is slided Road is mounted on by the slide groove of both sides in the protrusion of workbench, and the slideway tooth of sawtooth slide bottom is with being mounted on workbench The variable-frequency motor of bottom passes through engaged gears.
Based on the above technical solutions, the utility model can also do following improvement.
Further, the shielded closure mechanism includes the slideway being fixed on the spindle stock of chuck both sides, and sliding block leads to It crosses pin to be fixed on slideway, protective cover is installed to by upper bracket and lower carriage on the sliding block of both sides.
Further, the protective cover is mounted on the forepart of chuck.
Further, the angle grinder fixed seat is liftable structure.
The beneficial effects of the utility model are:
1. rational in infrastructure, simple, manufacturing cost is cheap.
2. operating with simplicity, operating cost is low, can effectively reduce production cost, improves efficiency.
3. process the form of thread it is complete, without hypodontia snaggletooth phenomenon.
Description of the drawings
Fig. 1 is a kind of structure diagram of thread machining device for carbon-carbon composites of the utility model;
Fig. 2 is the structure diagram of shielded closure mechanism in Fig. 1;
Fig. 3 is sawtooth slideway and workbench mounting structure schematic diagram.
Reference numeral record is as follows:1 spindle stock, 2 shielded closure mechanisms, 3 chucks, 4 angle grinders, 5, angle grinder are fixed Seat, 6 sawtooth slideways, 7 variable-frequency motors, 8 gears, 9 workbenches, 2-1 shields, 2-2 sliding blocks, 2-3 lower carriages, 2-4 upper brackets, 2- 5 pins, 2-6 slideways, 6-1 slideways tooth, 6-2 slide grooves.
Specific embodiment
The principle and feature of the utility model are described below in conjunction with attached drawing, example is served only for explaining this practicality It is new, it is not intended to limit the scope of the utility model.
A kind of thread machining device (referring to Fig. 1 Fig. 2 and Fig. 3) for carbon-carbon composites, including workbench 9, peace Spindle stock 1 mounted in 9 one end of workbench, the top installation shielded closure mechanism 2 of the chuck 3 in 1 front of spindle stock, angle Grinding machine 4 is mounted on by angle grinder fixed seat 5 on sawtooth slideway 6, and sawtooth slideway 6 is mounted on work by the slide groove 6-2 of both sides In the protrusion for making platform 9, the slideway tooth 6-1 of 6 bottom of sawtooth slideway passes through with the variable-frequency motor 7 mounted on 9, workbench bottom Gear 8 is engaged.Gear 8 is mounted on the output terminal of variable-frequency motor 7.
The shielded closure mechanism 2 includes the slideway 2-6, sliding block 2-2 that are fixed on the spindle stock 1 of 3 both sides of chuck It is fixed on by pin 2-5 on slideway 2-6, protective cover 2-1 is installed to the cunning of both sides by upper bracket 2-4 and lower carriage 2-3 On block 2-2.
The protective cover 2-1 is mounted on the forepart of chuck 3.
The angle grinder fixed seat 5 is liftable structure.
In use, barred body is clamped with chuck made of carbon-carbon composites, the protective cover whereabouts of shielded closure mechanism is located in The top of barred body, angle grinder control height is suitble to, is contacted convenient for angle grinder and barred body, when angle grinder is high-speed rotating, stick Body rotates under the drive of spindle stock, realizes and leaves screw thread trace in barred body, and shielded closure mechanism can place barred body at angle Excessive bending occurs under the action of grinding machine, and fracture occurs and collapses the problem of winged, makes process safer, the finished product of material Rate improves.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality Within new spirit and principle, any modifications, equivalent replacements and improvements are made should be included in the guarantor of the utility model Within the scope of shield.
