Technical Field

[0001] The invention belongs to the technical field of rudder blade parts processing equipment, and in particular relates to a rudder blade parts milling processing device. Background Art

[0002] The gas rudder blade is a part that controls the direction of a certain flight component. The top of the gas rudder blade is composed of multiple curved surfaces, connected to the curved surface is a circular plane, and the bottom is composed of a cylinder. In the early stage of processing, flat-nose pliers were used for clamping, single-piece clamping, and single-piece correction. The processing quality was unstable, and whether the size met the standard mostly depended on the technical level of the operator, and the correction time was long when clamping the parts. In order to solve the low production efficiency and problems in the production process, a rudder blade part processing device was designed. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a rudder blade parts milling processing device which has a simple structure, is easy to operate, can greatly shorten the correction time when clamping parts, and improves production efficiency.

[0004] The technical solution adopted by the present invention is: a milling processing device for rudder blade parts, including a base and a wedge clamping assembly; a plurality of groups of rectangular wedge grooves are provided on the base, the number of wedge grooves in each group of wedge grooves is two, and a rectangular positioning groove is connected to each end of the wedge groove, and the bottom surface of the positioning groove is higher than the bottom surface of the wedge groove; a positioning pin is respectively provided in the positioning grooves at both ends of a wedge groove in each group of wedge grooves; a wedge clamping assembly is installed in the wedge groove; the wedge clamping assembly cooperates with the positioning groove to clamp the rudder blade parts.

[0005] Furthermore, the wedge block clamping assembly includes two wedge blocks I, a screw and a wedge block II with an isosceles trapezoidal cross-section. A threaded hole is provided at the center of the wedge block groove, and a screw hole is provided on the wedge block II. The screw passes through the screw hole and is screwed to the threaded hole; the two wedge blocks I are symmetrically arranged on both sides of the wedge block II; the wedge surfaces of the two wedge blocks I are arranged opposite to each other and respectively cooperate with the two wedge surfaces of the wedge block II.

[0006] Furthermore, a group of rectangular wedge grooves are provided on the base.

[0007] Furthermore, the two side surfaces of the two positioning grooves at both ends of the wedge groove are flush with each other.

[0008] Compared with the prior art, the present invention has the following beneficial effects: The invention has a simple structure and low cost; and the invention utilizes a wedge clamping assembly to clamp the gas rudder piece, thereby shortening the time for workers to calibrate the product, freeing the product dimensional accuracy from the influence of the operator's skill level, and ensuring stable and reliable product quality.

[0017] The present invention will be further described below in conjunction with the accompanying drawings.

[0018] like Figure 2-5 As shown, the present invention includes a base 1 and a wedge clamping assembly 2; a group of rectangular wedge grooves are provided on the base (the number of wedge grooves is not limited to one group, and can be multiple groups), and the number of wedge grooves in each group of wedge grooves is two. A rectangular positioning groove 11 is connected at both ends of the wedge groove, and the bottom surface of the positioning groove 11 is higher than the bottom surface of the wedge groove. The two side surfaces of the two positioning grooves 11 at both ends of the wedge groove are respectively flush. A positioning pin 4 is respectively provided in the positioning grooves 11 at both ends of a wedge groove in each group of wedge grooves. The wedge groove is provided with a wedge clamping assembly 2; the wedge clamping assembly 2 cooperates with the positioning groove to clamp the rudder blade parts 3.

[0019] The wedge clamping assembly includes two wedge blocks I21, a screw 22 and a wedge block II23 with an isosceles trapezoidal cross section. A threaded hole 12 is provided at the center of the wedge groove, and a screw hole is provided on the wedge block II23. The screw 22 passes through the screw hole and is screwed to the threaded hole. The two wedge blocks I21 are symmetrically arranged on both sides of the wedge block II23. The wedge surfaces of the two wedge blocks I21 are arranged opposite to each other and respectively cooperate with the two wedge surfaces of the wedge block II23.

[0020] like Figure 6-8 As shown, when the present invention is used to process a gas rudder blade, the specific operations are as follows: The present invention can clamp a plurality of rudder blade parts 3 (gas rudder blades) at one time and process two processes simultaneously.

[0021] Process 1: different positioning grooves and threaded holes are machined on the plane of the base 1, the wedge clamping assembly 2 is placed in the middle of the positioning groove, the gas rudder is placed in the positioning groove, and the screws 22 are tightened to clamp the gas rudder. Process 1 and process 2 are clamped and processed at the same time.

[0022] Process 2: Place the positioning pin 4 into the positioning pin hole, and use the positioning pin 4 to ensure the shape and position tolerance of the parts. Place the gas rudder in the positioning groove of the base 1, so that the positioning pin hole of the part matches the positioning pin on the processing device, and expand the two wedge blocks Ⅰ21 of the wedge clamping assembly 2 by tightening the screw 22, and apply clamping force to the two sides of the part through the side of the wedge block Ⅰ21, so that the part fits with the positioning pin and the positioning groove, and realizes the clamping positioning of the surface and the pin.

[0023] Similarly, the number of the positioning grooves 11 can be increased, and a plurality of rudder blade parts 3 can be processed on one base 1 at the same time. One base can realize multi-step processing of the rudder blade parts 3 .
