The turntable type frock clamp of glass mold processing usefulness
Technical field
The utility model belongs to technical field of tooling clamps, is specifically related to a kind of turntable type frock clamp of glass mold processing usefulness
Background technology
frock clamp plays crucial effect in the production process of industrial products, the production of glass mold is no exception.So-called frock clamp is meant and is used in machining workpiece being carried out clamping or location, when production, do not have interference to reach the special equipment or the instrument of certain technological requirement, need satisfy usually, accurate positioning is reliable and requirement such as easy to operate.Because frock clamp has the exclusive characteristics of making certain product; Therefore the generalization degree is extremely low; Often by the mode self manufacture of production firm to cut the garment according to the figure of manufacturing machine product, the production firm of glass mold also is equipped with various frock clamps with homemade mode mostly.In recent years; Various medium-to-high grade machining centers are used by vast medium-sized and small enterprises; It is fast with quality is good and the standardization level advantages of higher to have speed by the Cutter Body Processing with Machining Center product, if but lack and the supporting frock clamp of machining center, just these advantages embodiment of having no way of so.Will putting into that machining center is implemented to carry nib such as carving characters, being drilled with, offers locating slot, offered the abrasion board slot as the glass mold of workpiece, processing vest eye (clothes-hook hole), mill triangle, interior overside silk (milling circular arc) and must the reliable clamping of glass mold be locked by frock clamp when attacking operation such as inner hole thread, and frock clamp is to the quick clamping of workpiece or to remove clamping be that the whether reliable of release is the vital factor of assurance Cutter Body Processing with Machining Center efficient and crudy.The notion of aforementioned machining center is meant instrument and the Digit Control Machine Tool that have automatic tool changer, change brill and after once clamping, can realize multiple operation processing according to program setting that has cutter, drilling tool and so on.
are before the technical scheme of Chinese invention patent application publication number CN101659015A (frock clamp that the processed glass mould is used) is released; Be not limited to aforesaidly to carve characters, be drilled with and carry nib, offer locating slot, offer the abrasion board slot, processing vest eye (being the clothes-hook hole), mill triangle, interior overside silk (promptly milling circular arc) and the hole attacked to establish screw thread be that the operation of tapping etc. is served as by milling machine, drilling machine and tapping machine etc. common but not numerical control usually separately; Cause workpiece week swivel link many, clamp that number of times is difficult to guarantee frequently that glass mold quality, process time are tediously long, drawback such as inefficiency and labor strength are big; That is to say that CN101659015A has solved this technical problem basically, the objective capable technique effect of Instructions Page 3 2-3 that embodied.
still; Still there is following shortcoming in above-mentioned CN101659015A: one of which; Because turntable (patent is claimed the revolution bed) under the driving of the actuating unit that is in transmission connection with gyroaxis, need turn round angle arbitrarily; Therefore the anxiety that only exists mould to scurry out to mould holding from the end of mold platform with each a pair of jig arm of mold platform both sides; Thereby cause the mould damage, and do not provide teachings in the location of lathe Y direction (being commonly defined as Y direction facing to operator's direction), the back is implemented to clamp again then is increased working strength of workers and influence operating efficiency on the one hand if mould is scurried out; Because of clamping, secondary influences crudy on the other hand; They are two years old; Because machining center is not equipped with the power drive mechanism that is used to order about the turntable rotation usually; Therefore in order to ensure, need work in-process to dispose power drive mechanism in the heart separately to turntable provides power, yet because the structure of machining center self ten minutes compactness and space are limited; Thereby work in-process to set up the difficulty of power drive mechanism in the heart bigger, and this patent application scheme does not provide the corresponding techniques enlightenment yet; They are three years old; The time that comparatively bothers and spend when frock clamp is changed and keeped in repair is tediously long; Therefore because the power drive mechanism on turntable and the machining center is in transmission connection, when will whole frock clamp be moved apart machining center, need passes through complicated operations and turntable and power drive mechanism releasing are in transmission connection; Its four, to the C&M of power drive mechanism trouble, because be difficult to power drive mechanism is shifted out machining center, and the space of the supplied upkeep operation on the machining center is very limited.
In view of above-mentioned prior art, be necessary to improve then, the applicant has done positive and useful design for this reason, and the technical scheme that will introduce below produces under this background
