Description
Technical Field
[0001] This utility model belongs to the technical field of rudder blade part processing equipment, specifically relating to a milling processing device for rudder blade parts. Background Technology
[0002] Gas turbine control blades are directional control components in aircraft. The top of the blade consists of multiple curved surfaces, connected to a circular plane, and the bottom is a cylinder. In the initial machining process, flat-jaw pliers were used for clamping and correcting individual parts, resulting in inconsistent machining quality. Whether the dimensions met standards largely depended on the operator's skill level, and the correction time during clamping was lengthy. To address the low production efficiency and problems encountered during production, a machining device for control blade parts was designed. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a milling device for rudder blade parts that is simple in structure, easy to operate, and can greatly shorten the calibration time when clamping parts and improve production efficiency.
[0004] The technical solution adopted by this utility model is: a milling device for rudder-type parts, including a base and a wedge clamping assembly; the base is provided with several sets of rectangular wedge grooves, each set of wedge grooves has two wedge grooves, and each end of the wedge groove is connected to a rectangular positioning groove, the bottom surface of the positioning groove is higher than the bottom surface of the wedge groove; a positioning pin is provided in the positioning groove at each end of one wedge groove in each set of wedge grooves; the wedge groove is provided with a wedge clamping assembly; the wedge clamping assembly cooperates with the positioning groove to clamp the rudder-type parts.
[0005] Furthermore, the wedge 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 into 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 each other and respectively mate with the two wedge surfaces of the wedge block II.
[0006] Furthermore, the base is provided with a set of rectangular wedge-shaped grooves.
[0007] Furthermore, the two sides of the two positioning grooves at both ends of the wedge groove are flush.
[0008] Compared with the prior art, the beneficial effects of this utility model are:
[0009] This invention has a simple structure and low cost; moreover, it uses a wedge clamping assembly to clamp the gas rudder blade, which shortens the time for workers to correct the product, and makes the product dimensional accuracy independent of the operator's skill level, so that the product quality is stable and reliable.

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] like Figure 2-5 As shown, this utility model includes a base 1 and a wedge clamping assembly 2. The base has a set of rectangular wedge grooves (the number of wedge grooves is not limited to one set, but can be multiple sets), with two wedge grooves in each set. A rectangular positioning groove 11 connects to each end of the wedge groove, the bottom surface of which is higher than the bottom surface of the wedge groove, and the two sides of the two positioning grooves 11 at both ends of the wedge groove are flush. A positioning pin 4 is provided in the positioning groove 11 at each end of one wedge groove in each set. The wedge groove is equipped with the wedge clamping assembly 2; the wedge clamping assembly 2, in conjunction with the positioning groove, is used to clamp the rudder-like parts 3.
[0020] The wedge clamping assembly includes two wedge blocks I 21, a screw 22, and a wedge block II 23 with an isosceles trapezoidal cross-section. A threaded hole 12 is located at the center of the wedge block groove, and a screw hole is located on wedge block II 23. The screw 22 passes through the screw hole and is screwed into the threaded hole. The two wedge blocks I 21 are symmetrically arranged on both sides of wedge block II 23. The wedge-shaped surfaces of the two wedge blocks I 21 are positioned opposite each other and respectively mate with the two wedge-shaped surfaces of wedge block II 23.
[0021] like Figure 6-8 As shown, the specific operation of this utility model when processing gas turbine blades is as follows:
[0022] This utility model can clamp multiple rudder-type parts 3 (gas rudders) at one time and process two processes simultaneously.
[0023] Step 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, and the gas rudder is placed in the positioning groove. At the same time, the screw 22 is tightened to clamp the gas rudder. Step 1 and Step 2 are clamped and processed simultaneously in one setup.
[0024] Step 2: Place the locating pin 4 into the locating pin hole to ensure the relevant dimensional and positional tolerances of the part. Place the gas rudder plate in the locating groove of the base 1, so that the locating pin hole of the part mates with the locating pin on the processing device. Tighten the screw 22 to expand the two wedge blocks I21 of the wedge clamping assembly 2, and apply clamping force to both sides of the part through the sides of the wedge blocks I21, so that the part fits with the locating pin and the locating groove, and achieves clamping and positioning of the surface and the pin.
[0025] Similarly, the number of positioning slots 11 can be increased, and multiple rudder-type parts 3 can be processed on one base 1. One base can realize the processing of multiple processes of rudder-type parts 3.
