Abstract

The utility model relates to an internal mould adjustable ring strut of an internal circle clamping device of a wind turbine generator shell, which comprises an upper circular ring and a lower circular ring. A plurality of supporting plates uniformly arranged in the circumference are connected between the upper circular ring and the lower circular ring. A bolt sleeve is arranged between optional two supporting plates adjacent to each other. Screw thread is arranged in each bolt sleeve. A bolt matched with the screw thread is arranged in each bolt sleeve. A retaining nut is connected on one end of each bolt arranged at the outer part of the bolt sleeve. Each retaining nut is connected with a rubber pad. The internal mould adjustable ring strut of the internal circle clamping device of the wind turbine generator shell has the advantages of simple structure and convenient use.

Description

The internal mold adjustable ring support of inner circle of wind driven generator shell clamping device

Technical field:

The utility model relates to a kind of adjustable ring support, particularly a kind of internal mold adjustable ring support of inner circle of wind driven generator shell clamping device.

Background technology:

The casing of wind-driven generator is when producing, need to use specific frock on lathe, to clamp processing,, add to produce vibration man-hour owing to casing is bigger, and in process, produce heat, thereby easily make workpiece deformation, increased the difficulty of processing of workpiece, and when using frock, need be according to the size of circle in the casing, the special making not only increased cost, and reduced efficient.

Summary of the invention:

The purpose of this utility model is in order to overcome above deficiency, and the internal mold adjustable ring support of inner circle of wind driven generator shell clamping device a kind of simple in structure, easy to use is provided.

The purpose of this utility model is achieved through the following technical solutions: a kind of internal mold adjustable ring support of inner circle of wind driven generator shell clamping device, comprise annulus and following annulus, be provided with 12 gripper shoes of evenly placing between last annulus and the following annulus along circumference, between any two adjacent gripper shoes, be provided with bolt sleeve, the upper surface of bolt sleeve is connected with the lower surface of last annulus, the lower surface of bolt sleeve is connected with the upper surface of following annulus, each bolt sleeve inwall is equipped with screw thread, each bolt sleeve inside is equipped with the bolt with threads engaged, each bolt places on the end of bolt sleeve outside and is connected with hold-down nut, and each hold-down nut all is connected with valve rubber.

The utility model compared with prior art has the following advantages: simple in structure, easy to use, and in use can be according to the size of workpiece, regulate bolt by hold-down nut, thereby make the big or small consistent of internal diameter that 12 bolts enclose and workpiece, thereby prevent Workpiece vibration, reduced the difficulty of processing of workpiece.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

The last annulus of number in the figure: 1-, 2-valve rubber, 3-gripper shoe, 4-bolt sleeve, 5-bolt, 6-hold-down nut.

The specific embodiment:

In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.

Show the embodiment of the internal mold adjustable ring support of a kind of inner circle of wind driven generator shell clamping device of the utility model as Fig. 1, comprise annulus 1 and following annulus, be provided with 12 gripper shoes 3 of evenly placing between last annulus 1 and the following annulus along circumference, between any two adjacent gripper shoes 3, be provided with bolt sleeve 4, the upper surface of bolt sleeve 4 is connected with the lower surface of last annulus 1, the lower surface of bolt sleeve 4 is connected with the upper surface of following annulus, be equipped with screw thread on each bolt sleeve 4 inwall, each bolt sleeve 4 inside is equipped with the bolt 5 with threads engaged, each bolt 5 places on the end of bolt sleeve 4 outsides and is connected with hold-down nut 6, each hold-down nut 6 all is connected with valve rubber 2, the utility model preferably is connected by 12 gripper shoes 3 that evenly are provided with along circumference between last annulus 1 and following annulus, this internal mold adjustable ring support is not only simple in structure, easy to use, and in use can be according to the size of workpiece, regulate bolt by hold-down nut 6, thereby make the big or small consistent of internal diameter that 12 bolts enclose and workpiece, thereby prevent Workpiece vibration, reduced the difficulty of processing of workpiece.
