Abstract
The utility model discloses a sheet type heat-dissipating groove machining clamp which comprises a vice, L-shaped pressing strips and U-shaped pad iron. The U-shaped pad iron is arranged in a clamping opening of the vice. The L-shaped pressing strips press the U-shaped pad iron in a buckling mode. The L-shaped pressing strips are two in number and are arranged on the two sides of the U-shaped pad iron respectively. The L-shaped pressing strips are arranged between the U-shaped pad iron and the vice. Compared with the prior art, when the vice is used for machining a part, the machining face is not shielded, clamping is of surface contact, the part can not be damaged by pressing, one surface can be machined only by clamping at a time, the original mode of clamping the surface for a plurality of times is changed into the mode of clamping the surface at a time, and the upper portion and the lower portion of the machined part can be protected from concave-convex deformation caused by uneven stress in the machining process.
Description
Technical field
The utility model relates to field of machining, particularly relates to a kind of thin plate class radiating groove clamp for machining.
Background technology
Large-area thin plate class heat sink plays the important function of heat radiation in cabinet module.And in mechanical processing process, often there is several factors to affect the final processing presentation quality of this workpiece, how to make the presentation quality of workpiece reach requirement, how to reduce the impact of various factors on outward appearance crudy, just become the thing that must consider before processing, namely will analyze affecting the factor of machining presentation quality.
Large-area thin plate class heat sink part is because Thickness Ratio is thinner, and area is large.Before with Tool in Milling radiating groove, likely just there is distortion, when milling radiating ribs, just increased difficulty.In process, part torsional deformation is serious, conventionally in Milling Processes, uses pressing plate to be pressed in the traditional clamping method on piece surface, and clamping is time-consuming, and labour intensity is large, and hanger and part are interfered mutually, need multiple clamping.In milling, need spiritual high concentration.In case cutter touches pressing plate.In process, due to pressing plate, be pressed in a point of part, part self stress and add the stress that man-hour milling produces and can not get discharging, causes after processing that part deformation is large, surface weighs wounded.In trimming process, to beat blowing to part, discharge stress, make piece surface press wound, cannot meet appearance requirement.
Utility model content
The purpose of this utility model is to provide a kind of clamp for machining, make adding man-hour, the active force of generation all, on fixture, is avoided part to be processed to bear clamping force and is made part to be processed produce upper and lower deformation of unevenness, keep part to be processed surfacing, the phenomenon that there will not be milling to wear.
The utility model adopts following technical scheme: a kind of thin plate class radiating groove clamp for machining, comprise vice, L shaped press strip, U-shaped parallels, and described U-shaped parallels is arranged in the jaws of vice, and described L shaped press strip is withheld on U-shaped parallels.
In technique scheme, described L shaped press strip is two.
In technique scheme, described L shaped press strip is separately positioned on the both sides of U-shaped parallels.
In technique scheme, described L shaped press strip is arranged between U-shaped parallels and vice.
When processing sheet radiating groove part, according to the appearance and size of part, prepare a U-shaped parallels and two L shaped press strips, first U-shaped parallels is placed on vice, then put the part that will process (part finished surface will higher than vice jaw), two L shaped press strips are pressed on part and U-shaped parallels, grip vice, strike lower L shaped press strip, make its compressing component, just can directly process.During with vice processing parts, machined surface does not block, and clamping is face contact, also can part not caused and be weighed wounded, and only need clamping once just can complete a surperficial processing, makes original multiple clamping be improved to clamped one time.
When vice clamps, part is to be placed in L shaped press strip and U-shaped parallels, the lock-filters clamp power of fiting only acts on L shaped press strip and U-shaped parallels, part itself does not afford the clamping force of vice, only be subject to two L shaped press strips pressure vertically downward, part can not produce the recessed distortion of epirelief, and part self is smooth, L shaped briquetting to the active force that presses down generation be traditional clamping method be pressed in piece surface pressure 40%.The phenomenon that adopts climb cutting to there will not be milling to wear in process, can also discharge the stress that part self internal stress and Milling Process produce, and is fully discharged.
The utility model compared with prior art, during with vice processing parts, machined surface does not block, and clamping is also face contact, also can part not caused and be weighed wounded, and only need clamping once just can complete a surperficial processing, make original multiple clamping be improved to clamped one time; And also can avoid man-hour unbalance stress to cause the deformation of unevenness up and down of part to be processed adding.
Accompanying drawing explanation
The utility model will illustrate by embodiment and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is side view of the present utility model;
Fig. 2 is top view of the present utility model;
Wherein: the 1st, vice, the 2nd, U-shaped parallels, the 3rd, L shaped press strip, the 4th, thin plate radiating groove part.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 and Figure 2, the utility model comprises vice 1, U-shaped parallels 2, L shaped press strip 3, when practical operation, vice 1 is fixed on milling machine workbench, adjust behind position, U-shaped parallels 2 is set in the jaws of vice 1, then thin plate radiating groove part 4 to be processed is lain in to U-shaped parallels 2 surfaces, the finished surface of thin plate radiating groove part 4 need to, higher than the jaw position of vice, then be withheld on thin plate radiating groove part 4 with two L shaped press strips 3; Then grip vice 1, the clamping force action of vice 1 is on L shaped press strip 3, so just guaranteed that the side of thin plate radiating groove part 4 does not stress, also guaranteed the fixed position of thin plate radiating groove part 4 simultaneously, facilitate the further processing of milling machine, because thin plate radiating groove part 4 sides do not stress, that is to say the situation that thin plate radiating groove part 4 is adding processing occurs while there will not be man-hour tradition to clamp concave-convex surface distortion and part milling and wears, because the utility model adopts disposable clamping, improved operating efficiency simultaneously.
Disclosed all features in this description, except mutually exclusive feature, all can combine by any way.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
