Abstract
The utility model relates to a spring retractable cross-section positioning dedicated rotating center which comprises a positioning main body, a tank body and a center, wherein the tank body is arranged on the positioning main body; an end cover is fixedly arranged at one side of the tank body; the center is arranged at the other side of the tank body; the interior of the tank body is sheathed with a sleeve; one end of the interior of the sleeve is coaxially provided with the center, and the other end of the interior of the sleeve is coaxially provided with a regulating nut; a central hole of the regulating nut is meshed with a screw; and the front end of the screw is extended into the sleeve and top-pressed at the tail part of the center by the spring. The spring retractable cross-section positioning dedicated rotating center has reasonable design, convenient use, simple operation and strong practicability. The centering and positioning can be realized by using the dedicated rotating center for primary clamping, thus improving the working efficiency, guaranteeing the machining precision and reducing the labor intensity.
Description
Technical field
The utility model belongs to field of machine tool equipment, and especially a kind of telescopic spring formula section is located special-purpose live centre.
Background technology
Need use top positioning when using the machine tooling axle at present.Because the Danfoss bent axle is more special, need adopts the Double Tops point when therefore processing its external diameter and with the end face location, and in process, need to carry out the centering of multiple clamping location, so that its major and minor axis is processed respectively.Owing to need repeatedly clamping repeatedly in the process, will inevitably cause occurring that machining accuracy is low, end product quality is difficult to assurance, long processing time, problem such as production efficiency is low and labor strength is big.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, reasonable in design, once can realize feeling relieved the location, can guarantee machining accuracy, enhance productivity, shorten the production time, the telescopic spring formula section that reduces labor strength locatees special-purpose live centre.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of telescopic spring formula section is located special-purpose live centre, comprise location main body, casing and top, casing is installed on the main body of location, and a side of casing installs end cap, and another side of casing is installed top, it is characterized in that: suit one sleeve in the casing, the coaxial installation of one end of sleeve inner is top, coaxial installation one adjusting nut of the other end of sleeve inner, and the centre bore of this adjusting nut meshes a screw rod, the front end of this screw rod stretches in the sleeve, and passes through a spring roof pressure at top afterbody.
And described sleeve is installed in the casing by bearing.
And, a check ring is set between described screw front end and the spring.
And, be positioned on the screw rod in the adjusting nut outside nut and a main shaft hold-down nut are installed.
And one handle is made in the rear end of described screw rod.
Advantage of the present utility model and beneficial effect are:
1, this special-purpose live centre adopts telescopic top and rotating sleeve is installed in casing, the end face of this sleeve and workpiece end face are fitted and are realized the location, the function that clamping can be realized feeling relieved, locating, needn't carry out multiple clamping, therefore shorten the production time, improved production efficiency.
2, this live centre had both played the centering effect of regular centre, had solved the difficult problem that accessory size is difficult to guarantee again, especially was fit to the processing of axial workpiece.
3, can realize centering and location because this special-purpose live centre carries out a clamping, therefore reduce working strength of workers.
4, the utility model is that a kind of reasonable in design, easy to use, simple to operate, practical telescopic spring formula end face is located special-purpose live centre.Use that this special use is top to be carried out clamping and can realize centering and location, thereby improved operating efficiency, guaranteed machining accuracy, alleviated labour intensity.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the vertical view (analysing and observe) of Fig. 1.
The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of telescopic spring formula end face is located special-purpose live centre, comprises location main body 1, casing 15 and top 7, and casing is installed in main body top, location, and a side of casing installs an end cap 9 by screw 10, and another side of casing is installed top.
Innovative point of the present utility model is: suit one sleeve 8 in the casing, and this sleeve is connected by bearing 11 with casing, is provided with spacer ring 12 and 13 between sleeve and the casing, and the two ends of sleeve and casing are by oil sealing 14 sealings.
The axis hole 17 of a band boss is made in the inside of sleeve, the coaxial installation of one end of sleeve axis hole is top, coaxial installation one adjusting nut 4 of the other end of sleeve axis hole, centre bore engagement suit one screw rod 16 of this adjusting nut, the front end of this screw rod stretches in the sleeve, and pass through a spring 6 roof pressures, and also be coaxially arranged with a check ring 5 between screw front end and the spring at top afterbody.
Be positioned at coaxial installation one nut 3 and main shaft hold-down nut 18 on the screw rod in the adjusting nut outside, one handle 2 is made in the rear end of screw rod.
Operation principle of the present utility model:
Top be can stretch and certain elasticity is arranged, fix on the centre bore of workpiece, realize centering.When the end face of workpiece fitted to the end face of sleeve, promptly the end face location utilized top elasticity to withstand the centre bore of workpiece.So both realized centering, with having realized the end face location.
