Abstract
The utility model relates to a cylindrical positioning and an upper and lower end face clamping fixture, comprising an upper clamping ring and an upper guiding ring which are disposed below a hydraulic cylinder of a fixture body. A fixture body base, corresponding to the hydraulic cylinder is provided with a lower pressing ring, and a workpiece is disposed between the guiding ring and the lower pressing ring. The fixture body base is provided with two adjustable locating rods along the circumferential direction of a central axis. The adjustable locating rod is provided with a positioning adjustable block. An angle A of 120 DEG is disposed between the two adjustable locating rods. The cylindrical positioning and an upper and lower end face clamping fixture is advantageous in that workpiece clamping of a precision boring process can be precisely and rapidly conducted; clamping time can be saved and production efficiency can be improved; processing precision and quality can be ensured.
Description
Technical field
The utility model relates to a kind of vertical right boring anchor clamps, and specifically, the utility model relates to a kind of cylindrical location and upper and lower end face clamping device.
Background technology
Lathe has obtained certain development to the processing of precision optical machinery, and in production and processing also to popularize; In vertical right boring, all adopt and go up the pressure type clamping mode, for the cylindrical location, all adopt centring ring and matched in clearance location; But this anchor clamps have two kinds of defectives: the one, and there is deviation in matched in clearance, can't realize precision positioning; The 2nd, after a large amount of again clampings and the use, the centring ring easy abrasion makes the positioning accuracy variation, thereby influences the crudy of workpiece; This installation way is unfavorable in vertical right boring, popularizing and using.
Summary of the invention
The utility model technical problem to be solved provides a kind of cylindrical location and the upper and lower end face clamping device that can directly locate processing to excircle of workpiece.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme.
This a kind of cylindrical location and upper and lower end face clamping device comprise the last trim ring and the last guide collar that are installed in clamp body hydraulic cylinder below, and the said clamp body pedestal corresponding with the clamp body hydraulic cylinder is provided with lower clamping ring, and workpiece is located between guide collar and the lower clamping ring.
In order to regulate the position of workpiece, main shaft circumference orientation, said clamp body pedestal upper edge is provided with two adjustable backstays.
In order to make adjustable backstay after adjusting, guarantee fixed-site, said adjustable backstay is provided with positioning adjust block.
The accurate location of adjustable backstay for ease, the angle A between the said adjustable backstay is 120 °.
Compared with prior art, the usefulness of the utility model is: adopt this device can fast, accurately realize the clamping workpiece to the right boring operation, save the clamping time, enhance productivity, guarantee the machining accuracy and the quality of workpiece.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of cylindrical location and upper and lower end face clamping device.
Among the figure: 1, clamp body hydraulic cylinder; 2, go up trim ring; 3, go up guide collar; 4, lower clamping ring;

The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in detail:
A kind of cylindrical location shown in Figure 1 and upper and lower end face clamping device comprise clamp body hydraulic cylinder 1, and said clamp body hydraulic cylinder 1 is installed on the vertical boring mill; Be provided with trim ring 2 below the clamp body hydraulic cylinder 1, the below of last trim ring 2 is provided with guide collar 3, and said guide collar 3 and the clamp body hydraulic cylinder 1 gone up is for excessively to cooperate; Below clamp body hydraulic cylinder 1 correspondence, be provided with clamp body pedestal 5, said clamp body pedestal 5 is provided with lower clamping ring 4; As shown in Figure 2; The adjusting of workpiece 6 positional precisions for ease is provided with two adjustable backstays 8 along the circumferencial direction of clamp body pedestal 5 axis, and adjustable backstay 8 is provided with positioning adjust block 7; For accurate location, the angle A between the adjustable backstay 8 is set to 120 °; Said workpiece 6 is arranged between guide collar 3 and the lower clamping ring 4.
Its concrete working method is following: before the work; To place on the lower clamping ring 4 with the identical standard ring of workpiece 6 location external diameter tolerance intermediate values, and be close to, regulate adjustable backstay 8 with adjustable backstay 8 end faces; Standard ring is transferred to best center, locking positioning regulating block 7; In the work, only need workpiece 6 is placed on the lower clamping ring 4, be pushed into gently contact and get final product, start clamp body hydraulic cylinder 1 then and press down, compress, begin right boring from the upper and lower end face with workpiece 6 with adjustable pilot pin end face.
It is emphasized that: above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
