Abstract
The invention discloses a clamp with functions of positioning an outer circle and clamping upper and lower end surfaces. The clamp comprises an upper press ring and an upper guide ring which are arranged below a clamp body hydraulic cylinder, wherein a lower press ring which is arranged on a clamp body base corresponding to the clamp body hydraulic cylinder; a workpiece is placed between the upper guide ring and the lower press ring, two adjustable positioning rods are arranged on the clamp body base and in the circumferential direction of a main axis, positioning adjustment blocks are arranged on the adjustable positioning rods, and the included angle (A) of the adjustable positioning rods is 120 degrees. The clamp provided by the invention has the advantages that workpieces can be rapidly and accurately clamped by use of the clamp in a fine boring process, the clamping time is reduced, the production efficiency is improved, and the machining accuracy and quality of the workpieces are improved.
Description
Technical field
The present invention relates to a kind of vertical right boring anchor clamps, specifically, the present invention 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, centring ring weares and teares easily, makes the positioning accuracy variation, thereby influences the crudy of workpiece; This installation way is unfavorable for popularizing in vertical right boring and using.
Summary of the invention
Technical problem to be solved by this invention 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 present invention is achieved by the following technical solutions.
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 described 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, described clamp body pedestal upper edge is provided with two adjustable backstays.
In order to make adjustable backstay guarantee fixed-site after adjusting, described adjustable backstay is provided with positioning adjust block.
For convenience of the accurate location of adjustable backstay, the angle A between the described adjustable backstay is 120 °.
Compared with prior art, usefulness of the present invention is: adopt this device can fast, accurately realize 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:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of a kind 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;
5, clamp body pedestal; 6, workpiece; 7, positioning adjust block; 8, adjustable backstay.
The specific embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of cylindrical location shown in Figure 1 and upper and lower end face clamping device comprise clamp body hydraulic cylinder 1, and described 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 described guide collar 3 and the clamp body hydraulic cylinder 1 gone up is for excessively to cooperate; Be provided with clamp body pedestal 5 below clamp body hydraulic cylinder 1 correspondence, described clamp body pedestal 5 is provided with lower clamping ring 4; As shown in Figure 2, the adjusting of workpiece 6 positional precisions for convenience 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 °; Described workpiece 6 is arranged between guide collar 3 and the lower clamping ring 4.
Its concrete working method is as follows: before the work, the standard ring identical with workpiece 6 location external diameter tolerance intermediate values placed on the lower clamping ring 4, 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 preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
