Abstract

The utility model relates to a hexagonal turret fixture used for a lathe tailstock. A turret body is provided with a hexagonal turret which is provided with six cutter installing and clamping holes and six positioning pin holes, the practical function of a tailstock is increased, and six kinds of cutters can be installed and clamped simultaneously at one time; the utility model solves three problems of long auxiliary man hour, high labor intensity, and large difficulty for quality assurance caused by that in the production, the lathe tailstock and a square cutter frame are replaced, installed, and clamped with cutting tools repeatedly to complete the machining program of the work. The hexagonal turret fixture used for a tailstock is designed and manufactured to solve the three problems in the production process of the factory, the utility model is used for an engine lathe and a precision meter lathe for three years, and the function of a capstan lathe (a turret lathe) can be provided. The utility model is an auxiliary tool which can improve the work efficiency, reduce the labor intensity, and ensure the product quality.

Description

Hexagonal turret clamp for lathe tail-stock

The utility model is the tailstock that is used for lathe, strengthens the utility function of tailstock, solves cannot not be installed the upward aid of cutlery more than five kinds of the square tool post of lathe and tailstock.

Present known tail stock once can only be installed a kind of or top or drill chuck head or drill bit or reamer ...The workpiece of processing multistation needs the cutlery more than five kinds just can finish, and just must change the required cutlery that is installed back and forth, and this cutlery that is installed of changing back and forth has in its production process for bulk article unavoidable the appearance:

One, strengthened subsidy man-hour;

Two, strengthened labour intensity;

Three, strengthened the difficulty that guarantees product quality.

The purpose of this utility model realizes: strengthen the utility function of tail stock, loading onto on the tailstock on the hexagonal turret clamp, six kinds of cutleries simultaneously can be installed.Produce needs according to our unit, can't buy on the market, have to be according to the aufbauprinciple of capstan lathe (turret lathe), self design.Solved the three big problems that occur in our unit's process of producing product through practicality: unproductive time is big; Labour intensity is big; Guarantee that the product quality difficulty is big.Good result in practicality more than 3 years thinks that the utility model is necessary to form a complete production network with the auxiliary accessory that is lathe, and the utility function and the production efficiency that enlarge engine lathe further develop.

The utility model is achieved in that the Morse taper shank of hexagonal turret clamp positioning core axle tightly inserts in the mohs tapered bore of tailstock centre sleeve, make capstan head body on the positioning core axle be close to the end face of sleeve, proofreading and correct after the axiality of capstan head body and hexagonal turret and lathe spindle rules on the end face of sleeve with the screw perforation on the capstan head body finds out the center, hole, punching, tapping are fixed to the capstan head body on the end face of sleeve with screw then, and be error free through the axiality of proofreading and correct capstan head body and capstan head and main shaft once more.Compress the hold-down screw of capstan head body and sleeve again, together bore dowel hole.Capstan head body and sleeve be connected with two body alignment pins, maintenance loading and unloading later on just needn't be proofreaied and correct axiality again.Hexagonal turret is contained on the spindle nose of car capstan head body, is to prevent the moving spacing rotation of screw by capstan head back-up ring and back-up ring.Six cutleries hole that is installed is arranged on the capstan head, and cutlery or cutlery dop are used for being installed.The back side of capstan head also has six locating holes, and locating hole has two effects here: the one, and alignment pin on the capstan head body inserts in the locating hole of hexagonal turret, just can guarantee the be installed axiality of hole and lathe spindle of hexagonal turret cutlery; The 2nd, the stability of maintenance cutlery when work.It is pressured spring that alignment pin on the capstan head body inserts or withdraw from locating hole on the hexagonal turret, fixedly handle, movable handle reach.The degree of tightness adjustment of alignment pin and movable handle is to be reached by the adjustment nut on the alignment pin and nut and cap.The be installed dop dog screw in hole of capstan head cutlery also has two effects here: the one, be used for fixing cutlery or cutlery dop; The 2nd, when tapping or mantle fiber, utilize the elongated slot on the dop body of be installed screw tap or screw die, can only be by dog screw restriction dop with the pitch advance and retreat of screw tap, screw die, and can not rotate, make screw tap, screw die and the Worker's Stadium not cause damage.

Since adopt such scheme, can be according to the different model of lathe and the size of processing work, and all available such scheme reaches identical same purpose.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is the structure assembling front view of the utility model first embodiment, along the cutaway view of II among Fig. 2-O-O II line.Be explained with the 1-23 in scheming.

Fig. 2 is the left view of the utility model structure installation diagram, along the cutaway view of the I among Fig. 1-O-O-O-O-I line.

8-17 among Fig. 1 .2 is that the utility model second embodiment explains.

18-23 among Fig. 1 .2 is that the 3rd embodiment of the present utility model explains.

Among the figure: 1, the anti-moving screw 8 of positioning core axle 2, capstan head body 3, body alignment pin 4, hold-down screw 5, hexagonal turret 6, capstan head back-up ring 7, back-up ring, alignment pin 9, stage clip 10, adjust nut 11, nut and cap 12, fixedly handle 13, screw 14, movable handle 15, handle bearing pin 16, packing ring 17, split pin 18, dop body 19, cutlery dop 20, dop pressure cap 21, dog screw 22, dop hole 23, dowel hole

Most preferred embodiment one: among Fig. 1, the Morse taper shank of positioning core axle (1) inserts in the tail stock tailstock sleeve, capstan head body (2), be close to sleeve end face, after proofreading and correct the axiality of capstan head body (2) and hexagonal turret (5) and lathe spindle, with the screw perforation on the capstan head body (2), the center is found out in line on sleeve end face, on sleeve end face, punch, after the tapping, after with hold-down screw (4) capstan head body (2) being fixed together, the axiality of proofreading and correct capstan head body and hexagonal turret hole and lathe spindle once more is error free, tightens hold-down screw (4), after connection is beaten dowel hole together with capstan head body and sleeve, with reamer the body alignment pin (3) of packing into is later cut with scissors in the hole, the utility model of maintenance loading and unloading later on just needn't be proofreaied and correct again.Hexagonal turret (5) is contained on the spindle nose of capstan head body (2), is to come spacing rotation by capstan head back-up ring (6) and the anti-moving screw (7) of back-up ring, and in the dop hole (22) on the capstan head operating position of cutlery.Qualification position when being exactly alignment pin (8) insertion dowel hole (23).
