Abstract
The utility model relates to a water-cooled polishing fixture for polycrystalline diamond, which comprises a clamping base, a clamping groove formed on the bottom surface of the clamping base, a pressurization groove formed at the upper end of the clamping base, a pressure head facing the pressurization groove, and a cantilever on which the pressure head is arranged. The utility model is characterized in that a water tank is arranged on the clamping base, the water tank is provided with a water inlet and a water outlet, a gland is arranged at the upper end of the water tank, a positioning and lifting rod is fixed on the gland, the positioning and lifting rod is connected with a supporting rod, the supporting rod is fixed on the cantilever. Owing to the design that the work piece clamping base rotates and the water tank is stationary, the heat generated during the work piece grinding process is transferred to the high-flow cooling water which is rapidly injected into and discharged from the water tank through the work piece clamping base and the water tank wall, so as to reduce the temperatures of the fixture and the work piece during the process, increase the polishing efficiency and improve the quality of polished products.
Description
Technical field:
The utility model belongs to superhard material Machining Technology field, is specifically related to a kind of polycrystalline diamond water-cooled polishing clamp that is used for the polishing processing usefulness of large scale polycrystalline diamond blade.
Background technology:
Large scale polycrystalline diamond goods are used for making the cutter of the various non-black metal materials of cutting more.In order to make cutter have good chip-breaking performance, to improve the precision and the surface quality of workpiece to be machined, the polycrystalline diamond surface of most of polycrystalline diamond goods needs polishing, makes it reach minute surface (surface roughness Ra ≦ 0.05 μ m).But in traditional polycrystalline diamond polishing processing, emery wheel, anchor clamps and polycrystalline diamond goods all can generate heat very soon.The consequence that the too fast meeting of generating heat causes has: 1. emery wheel is out of shape even burn, and then makes the emery wheel air spots; 2. polycrystalline diamond product deformation makes some position, surface be difficult for throwing, and some position is can jettisoning too much, and it is uneven the diamond layer integral thickness to occur, and polishing time is long, and it is low to cause polishing efficiency; 3. the polycrystalline diamond surface occurs and scratch defectives such as burn; 4. influence polycrystalline diamond product total quality; 5. influence the equipment resistance to overturning.Therefore, it is to improve polishing working (machining) efficiency and product quality that the temperature that the reduction polishing is caused raises, and the effective way of raising equipment overall performance.Traditional polishing clamp does not also have the design of heat sink at present, and in the course of the work, the non-constant of the heat-sinking capability of anchor clamps causes anchor clamps and workpiece programming rate very fast, and the intensification of polishing emery wheel is also very fast.Therefore, a kind of polishing clamp that possesses heat sink of exploitation seems and is necessary very much.
The utility model content:
In sum; In order to overcome the deficiency of prior art problem; The utility model provides a kind of polycrystalline diamond water-cooled polishing clamp; It is to adopt the rotation of clamping workpiece seat, and the non-rotary design of tank realizes the reduction of process anchor clamps and workpiece temperature, the raising of polishing efficiency and the raising of polishing product quality by the heat that grinding produces through the mode that clamping workpiece seat and flume wall are conducted into the big flow cooling water of injecting fast in the tank and discharging with workpiece.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of polycrystalline diamond water-cooled polishing clamp, it comprises the clamping seat, clamping seat bottom surface is provided with the clamping groove; Clamping seat upper end is provided with pressurized tank, and pressurized tank is corresponding with pressure head, and pressure head is arranged on the cantilever; Wherein: described clamping seat is provided with tank, and tank is provided with water inlet and delivery port, and the tank upper end is provided with gland; Be fixed with the location on the gland and draw high bar, the location is drawn high bar and is connected with support bar, and support bar is fixed on the cantilever.
Further, be provided with sealing ring between described gland and the tank upper surface.
Further, described tank upper end is provided with convexity, and the gland lower end is provided with groove, and protruding and groove cooperatively interacts, and is provided with sealing ring in the groove, and sealing ring is an O type circle.
Further, to draw high the quantity of bar be 1～3 in described location.
The beneficial effect of the utility model is:
1, the utility model is to adopt the rotation of clamping workpiece seat; The non-rotary design of tank realizes the reduction of process anchor clamps and workpiece temperature, the raising of polishing efficiency and the raising of polishing product quality by the heat that grinding produces through the mode that clamping workpiece seat and flume wall are conducted into the big flow cooling water of injecting fast in the tank and discharging with workpiece.
2, the utility model is in manipulating process, can conveniently realize the combination of clamping workpiece seat and tank or separates.Tank seals, and cooling water can inject tank fast and discharge tank, promptly can realize the circulation circulation of big discharge, realizes the reduction of anchor clamps bulk temperature thus, and the rising speed that reduces polishing emery wheel temperature.
3, the utility model convenient mounting and clamping possesses heat sink, and cooling-down effect is good, can solve the unfavorable factor in the polishing processing, with traditional polishing clamp mutually specific energy improve polishing efficiency more than 5 times.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the schematic top plan view of the utility model Fig. 1;
Fig. 3 is the utility model user mode sketch map.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
Like Fig. 1,2, shown in 3, a kind of polycrystalline diamond water-cooled polishing clamp, it comprises clamping seat 1; Clamping seat 1 bottom surface is provided with clamping groove 12, and clamping seat 1 upper end is provided with pressurized tank 10, and pressurized tank 10 is corresponding with pressure head 8; Pressure head 8 is arranged on the cantilever 7, and described clamping seat 1 is provided with tank 3, and tank 3 is provided with water inlet 2 and delivery port 11; Tank 3 upper ends are provided with gland 4, and tank 3 upper ends are provided with convexity, and gland 4 lower ends are provided with groove; Protruding and groove cooperatively interacts, and is provided with sealing ring 9 in the groove, and sealing ring 9 is an O type circle; Be fixed with two location on the gland 4 and draw high bar 5, the location is drawn high bar 5 and is connected with support bar 6, and support bar 6 is fixed on the cantilever 7.
During use; Workpiece is placed in the clamping groove 12 of clamping seat 1, clamping seat 1 is placed on the centre of tank 3, and the pressurized tank 10 of clamping seat 1 upper end is connected with pressure head 8; Through pressure head 8; External force acts in the pressurized tank 10 at clamping seat 1 center through cantilever 7 and pressure head 8, pressurizes to workpiece, and through the external force effect clamping seat 1 is rotated.Workpiece contacts with emery wheel 13, and workpiece is carried out grinding-polishing, because the positioning action of bar 5 is drawn high in the location, tank 3 is static with top.Cooling water injects from water inlet 2, discharges from delivery port 11.In the process that workpiece is polished, heat is conducted to tank 3 through clamping seat 1 by workpiece, is absorbed and discharge by cooling water, to reach the purpose of cooling again.When getting workpiece, the location is drawn high bar 5 and under external influence, can tank 3 be separated with clamping seat 1 with top, and clamping seat 1 can take off, and takes out workpiece.
