Description

Technical Field

[0001] The invention relates to the technical field of turbine disc machining, in particular to a turbine disc tenon-and-groove broaching machine indexing plate. Background Art

[0002] The turbine disk is an important component of the aerospace engine. It is connected with the corresponding shaft and blades to form the rotor part of the engine. The turbine disk needs to work for a long time in a harsh environment of high speed, high temperature and high pressure. Therefore, the material selection of the turbine disk generally uses high-strength and high-temperature resistant materials. The structural design of the turbine disk is also relatively complex, especially the fir-tree-shaped straight tooth groove on it has a relatively complex structure and high manufacturing precision requirements.

[0003] There are many tenons on the outside of the turbine disc and they are evenly distributed, so a machine tool is needed to cut them. In order to ensure that the spacing between each tenon is equal, a dividing plate is used.

[0004] The prior art discloses a vertical and horizontal dual-purpose dividing plate. The hole spacing of the existing vertical and horizontal dual-purpose dividing plate is fixed. When the size of the T-slot of the worktable of the machine tool is inconsistent with the size of the installation hole of the vertical and horizontal dual-purpose dividing plate, the only solution is to add a machine tool pressure plate, etc. Although the problem can be solved, the installation is time-consuming, the process is complicated, the aesthetics is low, and the stability is poor, and it is easy to interfere with other equipment. The vertical and horizontal dual-purpose dividing plate of the present invention includes a base, a main body fixedly connected to the base is provided above the base, a dividing chuck is installed above the main body, and a positioning part connected to the dividing chuck is provided on the side of the main body; the main body is provided with a worm, and a crank is provided through the worm; the base is provided with a fixedly connected first stand, and the first stand is vertically arranged on the side of the base; the base is provided with a movably connected second stand, and at least a part of the second stand is on the same side of the base as the first stand.

[0005] The above-mentioned dividing plate is adjusted by hand crank, which has the following defects: if an outsider accidentally touches the crank handle, the dividing plate will rotate, resulting in an inaccurate angle. Therefore, there is no device to lock the dividing plate to solve the defect. At the same time, the accuracy of hand crank adjustment is difficult to control, resulting in inconsistent mortise and tenon spacing on the outside of the turbine disk. Therefore, a locking device for adjusting the rotation angle of the dividing plate is used to solve the defect. Summary of the invention

[0017] The present invention has the following beneficial effects:

[0018] (1) The rack is driven to move horizontally in the slide groove by the extension of the electric push rod, and the rack drives the gear plate and the rotating shaft A to rotate. The teeth on the rack are set to be short, and the extension and retraction control stroke of the electric push rod matches the rack.

[0019] On the contrary, when the electric push rod pulls the rack back, the ratchet plate is locked by the pawl head, and the shaft A will not rotate. The gear plate is affected by the pulling force, and the T-type clamp head will shrink to the installation slot, and the gear plate and the shaft A will be unlocked. In this way, the electric push rod ensures that the shaft A rotates when the rack goes, and the shaft A cannot rotate when the rack comes back.

A ring groove B is provided at the bottom of the fixed shell, and the sliding rod and the pressure head in the locking mechanism extend into the ring groove B. When unlocked, the push-up spring pushes the sliding bar, the extension rod and the locking plate upward, so that the locking plate does not contact the inner bottom wall of the ring groove B. When locked, the output end of the cylinder stretches and pushes the trapezoidal block into the trapezoidal hole. Using the inclined surface of the trapezoid, the trapezoidal block will squeeze the sliding bar downward, and then the locking plate will be tightly pressed against the inner bottom wall of the ring groove B, thereby locking the rotating shell and preventing accidental rotation from causing inaccurate angles.

[0054] Working principle: When in use, the rack 808 is driven to move horizontally in the slide groove 811 by the extension of the electric push rod 809, and the rack 808 drives the gear plate 801 and the rotating shaft A600 to rotate. The teeth on the rack 808 are set shorter, and the telescopic control stroke of the electric push rod 809 matches the rack 808. Each time the rack 808 slides outward and expands once, the gear plate 801 rotates by six degrees each time, and the ratchet plate 701 also rotates a tooth gap. The torsion spring 704 immediately controls the pawl head 702 to press against the tooth gap of the ratchet plate 701, and then the rotating shaft A600 is locked, thereby achieving the purpose of locking the indexing plate to prevent accidental rotation;

[0055] On the contrary, when the electric push rod 809 pulls the rack 808 back, the ratchet plate 701 is locked by the pawl head 702, and the rotating shaft A600 does not rotate. However, the gear plate 801 is affected by the pulling force, and the T-type clamp 804 shrinks toward the installation slot 802, and the gear plate 801 and the rotating shaft A600 are unlocked. In this way, the electric push rod 809 ensures that the rotating shaft A600 rotates when the rack 808 goes, and the rotating shaft A600 cannot rotate when the rack 808 comes back. In this way, the gear plate 801 and the rotating shaft A600 will rotate six degrees each time, and then rotate with the external turbine plate body 500, thereby achieving the purpose of accurately controlling the rotation angle of the dividing plate.

[0056] The extension of the electric push rod 809 will eventually cause the rotating shell 300 to rotate in the fixed shell 200, and a locking mechanism 900 is provided in the fixed shell 200. An annular groove B910 is provided at the bottom of the fixed shell 200, and the extension rod 908 and the pressure head 1014 in the locking mechanism 900 extend into the annular groove B910. When unlocked, the push-up spring 904 pushes the sliding bar 902, the extension rod 908 and the locking plate 909 to move upward, so that the locking plate 909 does not contact the inner bottom wall of the annular groove B910. When locked, the output end of the cylinder 907 extends and pushes the trapezoidal block 906 to insert into the trapezoidal hole 905. Using the inclined surface of the trapezoid, the trapezoidal block 906 will squeeze the sliding bar 902 downward, and then the locking plate 909 will be tightly pressed against the inner bottom wall of the annular groove B910, thereby locking the rotating shell 300 to prevent accidental rotation and causing an inaccurate angle.

[0057] The turbine disc body 500 is pre-mounted on the outer periphery of the vertical rod 1011, and the turbine disc body 500 is placed on the surface of the shell 400. The bevel gear 1004 is driven by the driving motor 1005 to rotate, and the bevel gear 1004 drives the bevel gear ring 1003 to rotate, and then the disc 1002 rotates around the rotating shaft B1001. A spiral tooth groove 1006 is provided on the upper surface of the disc 1002, and a tooth plate 1007 is meshed on the spiral tooth groove 1006. Then the rotating disc 1002 Then, the four sliders 1008 will be driven to expand synchronously, ensuring that the four vertical rods 1011 are pressed against the inner diameter of the turbine disc body 500, thereby clamping the turbine disc body 500. At the same time, when the vertical rods 1011 are close to the inner diameter of the turbine disc body 500, the pressure head 1014 is pulled up in advance, placed on the upper surface of the turbine disc body 500 and released, and the push spring 1015 can make the pressure head 1014 press tightly against the top of the turbine disc body 500, thereby fixing the turbine disc body 500.
