Detailed description of the invention
The utility model threaded rod grinds an embodiment of flat frock as shown in Fig. 3 ~ Fig. 7, comprise the overall upper grip slipper 10 for rectangular shape and lower grip slipper 20, the bottom surface of upper grip slipper 10 and the end face of lower grip slipper 20 are respectively equipped with the upper circular arc holding tank 11 of a row and lower circular arc holding tank 21, and upper circular arc holding tank 11 and lower circular arc holding tank 21 run through the width of corresponding grip slipper respectively and the length direction along corresponding grip slipper is arranged side by side.Each upper circular arc holding tank 11 and lower circular arc holding tank 21 have upper arc clamping face 12 for clamping processed bolt 60 and arc lower clamping face 22 respectively, and corresponding up and down one upper circular arc holding tank 11 and lower circular arc holding tank 21 form one group.Above-mentioned upper arc clamping face 12 and arc lower clamping face 22 have the curvature identical with the curvature of corresponding processed bolt 60, can ensure larger contact area, prevent ridge from deforming.In order to ensure axiality and the uniformity of upper circular arc holding tank 11 and lower circular arc holding tank 21, upper and lower circular arc holding tank dislocation when avoiding clamping bolt and crush screw thread, the upper circular arc holding tank 11 on upper grip slipper 10 and the lower circular arc holding tank 21 on lower grip slipper 20 are by the disposable machine-shaping of Linear cut.In order to avoid the threading power of bolt crosses macrolesion ridge, add should make circular arc holding tank 11 man-hour, lower circular arc holding tank 21 has less roughness.
The corresponding end of upper circular arc holding tank 11 and lower circular arc holding tank 21 is provided with the side channel mouth 30 supplying the position to be processed of screw rod to stretch out, side channel mouth 30 is respectively equipped with the axially extended supporting cantilever 50 along upper circular arc holding tank 11 and lower circular arc holding tank 21 perpendicular to the both sides of above-below direction, described supporting cantilever 50 has the holding face 51 for supporting threaded rod, holding face 51 is the circular arc coplanar with corresponding arc clamping face, can the projecting end of double thread bar play a supporting role, effectively reduce the stressed of the holding portion of threaded rod, prevent the ridge of holding portion impaired.Supporting cantilever 50 also has the top planes for exposing for the threaded rod plane on threaded rod, does not affect the processing of threaded rod on emery wheel 70 pairs of bolts.
Upper grip slipper 10 is provided with the screwed hole 13 of up/down perforation, lower grip slipper 20 is provided with up/down perforation and the screw perforation corresponding with described screwed hole 13, corresponding pinching screw 40 screws in described screwed hole 13 through described bolt penetration hole 23, form clamp system, for make upper grip slipper 10 and lower grip slipper 20 close to each other threaded rod is clamped between described upper arc clamping face 12 and arc lower clamping face 22.Lower grip slipper 20 is corresponding with the head of pinching screw 40, and the screw perforation on it is counter sink, can sink to, be convenient to threaded rod and grind the clamping of flat frock on Grinder bench for the head of pinching screw 40.Upper arc clamping face 12 and the radian corresponding to arc lower clamping face 22 are all less than π radian, when making the processed bolt 60 of clamping upper have between grip slipper 10 and lower grip slipper 20 between the upper and lower every, thus be convenient to adjust clamping dynamics by pinching screw 40.The middle part that pinching screw 40 corresponds to lower grip slipper 20 and upper grip slipper 10 length direction is arranged, and can play good clamping effect, and can reduce pinching screw 40 quantity, be convenient to workpiece loading and unloading.
The upside of upper grip slipper 10 and the downside of lower support seat are respectively equipped with for being supported on upper supporting surface on surface grinding machine workbench and lower support face, and described upper supporting surface and lower support face are formed for clamping to the clamping structure on surface grinding machine workbench.The bottom land of upper circular arc holding tank 11 equals the distance of bottom land to described lower support face of lower circular arc holding tank 21 to the distance of described upper supporting surface, after processing the threaded rod plane of side, threaded rod is ground flat frock integrated overturn, the processing of threaded rod opposite side can be carried out, do not need repeatedly to debug lathe and contraposition, easy to operate, effectively can improve working (machining) efficiency.
When using above-mentioned threaded rod to grind the threaded rod grinding threaded rod plane of flat frock to processed bolt 60, first bolt is placed between upper arc clamping face 12 on upper grip slipper 10 and the arc lower clamping face 22 of lower grip slipper 20, makes the position to be processed of threaded rod stretch out upper circular arc holding tank 11 corresponding in groups up and down and the side channel mouth 30 of lower circular arc holding tank 21; Then, screw pinching screw 40, make grip slipper 10 and lower grip slipper 20 close to each other threaded rod is clamped between described upper arc clamping face 12 and arc lower clamping face 22; Then, threaded rod being ground flat frock relies on lower support face to be adsorbed onto on Grinder bench, emery wheel 70 grinding is used to go out the threaded rod plane of respective side, then, threaded rod is ground flat frock integrated overturn, in dependence, supporting surface is adsorbed onto on Grinder bench, uses emery wheel 70 grinding to go out the threaded rod plane of opposite side, completes the processing of threaded rod plane.Use this frock not only to solve surface grinding machine and the problem of machining screw bar and plain-milling machine cannot add drawback existing for man-hour, burr is less, without the need to carrying out loaded down with trivial details manual deburring operation, save processing charges, and project organization is relatively simple, easy to operate, cost is low.Through sampling, adopt this frock on surface grinding machine double thread bar mill flat flat with milling on milling machine compared with, machining accuracy is higher, can effectively avoid overproof, crush, the problem such as to damage, and without the need to repeating debugging lathe and location after initial workpiece debugging, once can process more than one piece product, improve working (machining) efficiency, shorten the Product processing cycle, reduce production cost.
In the above-described embodiments, upper circular arc holding tank 11 and lower circular arc holding tank 21 are provided with many groups, and what clamp system adopted is be located in the pinching screw 40 between grip slipper 10 and lower grip slipper 20.In other embodiments of the present utility model, upper circular arc holding tank 11 and lower circular arc holding tank 21 also can only arrange one group, clamp system also can replace with other forms, corresponding flange is such as set on upper grip slipper 10 and lower grip slipper 20, flange arrangement arranges bolt or screw realization clamping.In addition, in the above-described embodiments, upper grip slipper 10 and lower grip slipper 20 are respectively equipped with supporting surface and lower support face as clamping structure, the process requirements of bilateral threaded rod plane on bolt can be adapted to, in other embodiments, for needing the workpiece processing one-sided threaded rod plane, also can side supporting surface be only set; And clamping structure also can replace with other forms according to the counter structure of Grinder bench, the clamping that threaded rod grinds flat frock can be realized.Moreover the supporting cantilever 50 in above-described embodiment is nonessential structure, also can save in other embodiments.
