Abstract
The utility model discloses a locating and clamping device utilizing a thread mandrel or thread sleeve, which comprises a pull rod, a main body, a thread pull rod, a locating plate and set screws; the pull rod is connected with the oil cylinder at the rear part of a lathe main shaft, the ladder-type thread pull rod is mounted at the front end of the pull rod, the main body is fixed on the outer edge of the thread pull rod through the set screws and the shaft, the locating plate is mounted on the front end surface of the main body, the thread pull rod extends from the locating plate, and working pieces are mounted at the front end of the thread pull rod. An oil cup capable of pouring lubricant into the oil accommodating cavity between the thread pull rod and the main body can be mounted on the main body. The utility model can be applied extensively to the numerical control lathe, which not only can improve the precision of the working pieces, but also can relieve the labor intensity of operating staff to the maximum degree, shorten the auxiliary time for part processing and improve the work efficiency, as a result the automation is convenient to be realized.
Description
Technical field
The utility model relates to a kind of screw thread plug (or thread bush) of using and locatees the device that clamps part, relates to a class specifically and need carry out part (screw thread of such part has higher axiality to require with profile to be processed or endoporus) quick, convenient, the reliable positioning clamping device of screw thread plug that turning is processed on numerically controlled lathe.
Background technology
In machine industry, numerically controlled lathe is widely used, and is used for processing dish class or various parts such as axle class etc.The many needs with the parts of screw threads as the location benchmark wherein arranged, also need operation break-down size, end face or the like later on performing screw thread.Existing universal technology can not be fast, convenient, reliable processing work, and guarantee the machining accuracy of workpiece, and production efficiency is lower, is unfavorable for producing in enormous quantities.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple, and the location that is used for screw thread plug on the numerically controlled lathe or thread bush reliably clamps component device.
The technical solution of the utility model is: a kind of positioning clamping device with screw thread plug or thread bush, and it comprises pull bar, main body, thread, positioning disk and holding screw; Described pull bar is connected with the oil cylinder at lathe spindle rear portion, stair-stepping thread is installed in the pull bar front end, and main body is fixed on the thread outer rim by holding screw is coaxial, and positioning disk is installed on the front end face of main body, thread stretches out positioning disk, at the thread front end workpiece is installed.In the appearance oil pocket that can be equipped with on the main body between thread and main body, inject the lubricating cup of lubricating oil.
Because pull bar is connected with the oil cylinder at spindle of numerical control lathe rear portion, driving pull bar, thread by hydraulic oil input driving oil cylinder piston moves backward, the drive workpiece moves, make workpiece paste mutually with positioning disk firmly, carry out fine positioning, thereby effectively control the length of workpiece, and reach the purpose that the location clamps.This device only need screw in about half just passable when the dress workpiece, does not need to be screwed into fully the end, and the range error that screws in length can be remedied by the stroke of oil cylinder.
During installation, at first workpiece is screwed in thread, the oil cylinder that is connected with the spindle of numerical control lathe rear portion by pull bar then, driving pull bar, thread by hydraulic oil input driving oil cylinder piston moves backward, the drive workpiece moves, make workpiece lean on the jail with positioning disk firmly, reach the purpose that the location clamps.
The beneficial effects of the utility model are: 1, simple in structure, reliable, required pressure oil can obtain from the hydraulic system of lathe.2, screw thread and the length difference according to part to be processed designs thread, and be applied widely, alleviated labor intensity of operating personnel, shortened the non-cutting time of part processing, improved operating efficiency, is convenient to realize automation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1: a kind of positioning clamping device with screw thread plug or thread bush comprises pull bar 1, main body 3, thread 4, positioning disk 5 and holding screw 8; Described pull bar 1 is connected with the oil cylinder at lathe spindle rear portion, stair-stepping thread 4 is installed in pull bar 1 front end, main body 3 is by holding screw 8 coaxial being fixed on thread 4 outer rims, positioning disk 5 is installed on the front end face of main body 3, and thread 4 front ends stretch out positioning disk 5 and are used to install workpiece 6.
Lubricating cup 7 can inject lubricating oil in the appearance oil pocket between thread 4 and the main body 3, do like this and can reduce friction between thread 4 and the main body 3, and reaching increases thread 4 and the main body purpose in 3 service lifes.Holding screw 8 can prevent the relative motion when dismounting workpiece 6 between thread 4 and the pull bar 1, and then prevents that thread 4 from coming off with pull bar 1, guarantees the security reliability of this device.Can make that the screw thread of thread 4 is concentric with the main shaft of lathe as required from cutting thread after thread 4 assemblings, can effectively improve the machining accuracy of workpiece 6 like this.Can the perpendicularity of the end face and the main-shaft axis of positioning disk 5 can be guaranteed so as required from face work after positioning disk 5 assemblings, the machining accuracy of workpiece 6 can be further effectively improved like this.
