Abstract
The utility model discloses a screw tap clamp for a lathe. A clamp body is provided with an outer surface used for clamping of a three jaw chuck of the lathe. A round hole and a square hole respectively matched with a round handle and a square of the tail portion of a screw tap are arranged inside the clamp body and coaxial with the body. At least one group of threaded holes and lock bolts are arranged in the position of the square hole along the radial direction of the body and used as locking devices. A through hole communicated with the square hole is arranged inside the clamp body and overlaps with or parallels to the axis of the square hole. The clamp body is a regular hexagonal prism body. The screw tap clamp for the lathe is simple in structure, low in cost capable of achieving quick assembly and disassembly, and convenient to assemble and disassemble.
Description
Technical field
The utility model relates to the screw tap clamp that a kind of machining is used, particularly a kind of screw tap for tapping anchor clamps for the lathe three-claw chuck.
Background technology
When using lathe that nut is carried out tapping, because the screw tap afterbody is directly clamping on lathe of four directions, screw tap all is first afterbody to be ground into the three parts, then uses the scroll chuck clamping.This mode is tighter to Geometrical Tolerance Principle behind the screw tap mill, be difficult for processing and long in time limit, cost is high, simultaneously, every rhizoid cone as an alternative all needs to carry out tool grinder, also needs repeatedly to lock dismounting during clamping and debugs, and has a strong impact on the product process-cycle.
Application number is that the Chinese patent of CN201020515443.1 discloses a kind of tapping clamp of nut for lathe, comprise a left side, right two parts, it is characterized in that: left-half is by pull bar, scroll chuck, non-slipping block, axle sleeve, little axle, roller, mandrel, the screw tap seat, screw tap seat holding screw, screw tap forms, the axle sleeve clamping is fastened on the lathe three-claw chuck by pull bar, be provided with non-slipping block and the axle sleeve cunning is joined at axle sleeve, little axle crosses roller and mandrel can roll in the opening elongated slot at axle sleeve middle part, screw tap and screw tap seat are fixed by screw tap seat holding screw, right half part is by carriage, workseat, the workseat holding screw, baffle plate, attachment bolt forms, workpiece and workseat are by on the workseat holding screw, baffle plate is fixed on a kind of tapping clamp of nut for lathe on the carriage right side by attachment bolt, comprise a left side, right two parts, it is characterized in that: left-half is by pull bar, scroll chuck, non-slipping block, axle sleeve, little axle, roller, mandrel, the screw tap seat, screw tap seat holding screw, screw tap forms, the axle sleeve clamping is fastened on the lathe three-claw chuck by pull bar, be provided with non-slipping block at axle sleeve, axle core and axle sleeve cunning are joined, little axle crosses roller and mandrel, roller can roll in the opening elongated slot at axle sleeve middle part, screw tap and screw tap seat are fixed by screw tap seat holding screw, right half part is by carriage, workseat, the workseat holding screw, baffle plate, attachment bolt forms, workpiece and workseat are fixed on the carriage by the workseat holding screw, and baffle plate is fixed on the carriage right side by attachment bolt.Be connected by the screw tap seat between its jig main body and the screw tap, and need by the Anti-slip cover clamping to scroll chuck, complex structure, drive connection is many, is difficult for making and using.
The utility model content
The purpose of this utility model provide a kind of simple in structure, cost is low and the lathe screw tap for tapping anchor clamps being convenient to load and unload.
In order to realize above purpose, the technical solution adopted in the utility model is: a kind of lathe screw tap clamp, comprise jig main body and locking device, and described jig main body has can be for the outer surface of lathe three-claw clamping chuck; Justify handle and cubic circular hole and the square hole that cooperates with coaxial being provided with respectively of main body with the screw tap afterbody in the jig main body; Described square hole position radially is provided with at least one group of screwed hole and clamping screw as locking device along jig main body.
This design only needs jig main body can realize the installation of screw tap, simple in structure, reliable transmission, other uses clamping screw to realize being fixedly clamped, tighten or unclamp clamping screw and can realize quick dispatch, remove screw tap afterbody four directions grinding process from and reached repeatedly adjustment process, greatly shortened processing capacity, processing charges and production life cycle.The shape of jig main body can be all or only the clamping section adopt the common shapes such as cylindrical, positive six prismatics, perhaps have other shapes on three planes that can be installed.
With described square hole dead in line or parallelly be provided with the through hole that communicates with square hole, even screw tap fractures, also can easily screw tap be released from non-installation end in the described jig main body.
Described jig main body is positive hexagonal prism, is conducive to the reliable clamping of scroll chuck and transmission.
Description of drawings
Bottom in conjunction with specific embodiments accompanying drawing the utility model is described in further detail.
Fig. 1 is that screw tap passes through the schematic diagram of anchor clamps clamping to the lathe three-claw chuck;
Fig. 2 is screw tap clamp front view partial sectional view;
Fig. 3 is the screw tap clamp right view.
Each Reference numeral title is as follows among the figure: 1 scroll chuck, 2 clamping screws, 3 jig main bodies, 4 circular holes, 5 square holes, 6 screw taps, 7 screw tap afterbodys circle handle, 8 screw tap afterbodys four directions, 9 screwed holes.
The specific embodiment
A kind of lathe uses the embodiment of screw tap clamp shown in Fig. 1 ~ 3, comprise jig main body 3 and locking device, this jig main body 3 is positive hexagonal prism, justify handle 7, four directions 8 circular holes that cooperate 4, square hole 5 with coaxial being provided with respectively of main body with screw tap 6 afterbodys in the main body 3, described square hole 5 is through hole, and described locking device is radially to be arranged on square hole 5 near screwed hole 9 and the clamping screw 2 of circular hole position along main body 3.Should be noted that: the processing of circular hole 4 and square hole 5 will with screw tap 6 cooperate as far as possible accurate, with 6 work of reduce screw tap during stressed and clamping screw on the impact of its axiality.
Working method: during use with the anchor clamps clamping of positive hexagonal prism to scroll chuck 1, clamping screw 2 is unclamped, insert screw tap 6 and also shift the bosom onto, clamping screw 2 gets final product again.6 damages maybe need be changed such as screw tap, first clamping screw 2 are unclamped, and screw tap is extracted or released and can fast and easy finish replacing with instrument from the through hole other end.
In other embodiment of the present utility model, described square hole 5 also can be made blind hole, and then along square hole 5 axis or the axis through hole that be arranged in parallel with it, to reduce processing capacity; Described clamping screw 2 also can adopt the forms such as hexagon socket head cap screw, and described screwed hole 9 also can adopt the countersunk head screwed hole, described clamping screw and screwed hole also can arrange a plurality of so that locking is more reliable and when reducing lock-screw on the impact of screw tap axiality.
