[0003] The improved device needs to successfully solve the following problems:

[0004] 1. The clamping of the actuating cylinder is inconvenient, time-consuming and laborious; 2. Due to the long-term wear of the bushing, the pin positioning holes of the support, the bushing and the rotating shaft are misaligned, resulting in the positioning pin being unable to be accurately inserted into the positioning hole, losing the angle adjustment function; 3. The support is processed by a split structure, and the coaxiality is reduced after assembly. The rotating shaft is easily worn during rotation, reducing the service life. Summary of the Utility Model

Detailed implementation manners

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below.

[0035] As Figures 1 to 19 shown, a multi-station clamping control device for a horizontal tail actuator includes:

[0036] A support assembly, as the frame of the entire device, is fixed on the workbench surface and plays a supporting role;

[0037] A rotating assembly, which is installed on the support assembly and can rotate circumferentially to achieve angle control in the vertical direction;

[0038] A clamping assembly, which is arranged on the rotating assembly and is used to clamp the outer shell of the horizontal tail actuator, playing a role of clamping and fixing;

[0039] An angle control assembly, which is used in cooperation with the rotating assembly to achieve angle control in a very simple way.

[0040] The support assembly includes a base plate 10, a support 11 connected to the base plate 10 by a third screw 29, a first cylindrical pin 25 arranged on the base plate 10, and a bolt 21, a nut 23, and a flat washer 22 arranged on the base plate 10 and used for locking on the fixed tabletop.

[0041] The original support is assembled by two supports with the same structure, and the cumulative errors generated during the processing and assembly cannot be eliminated. Excessive errors will reduce the coaxiality of the shaft holes of the two supports, resulting in severe wear of the rotating shaft 16 during use and affecting the service life. The structure is optimized to design the two identical supports 11 as an integral type, and a single clamping is performed during processing, which can ensure high coaxiality and is easy to install.

[0042] The support assembly, as the foundation of the entire device, is fixed to the workbench with bolts. The bottom plate 10 and the support 11 are fixedly connected with bolts 21. After all positions are fixed, pin holes are configured on the bottom plate 10, and the cylindrical pin one 25 is inserted to complete the secondary precise positioning of the bottom plate 10 and the support 11.

[0043] A total of 4 sets of bolts 21, nuts 23, and flat washers 22 are reserved on the entire bottom plate 10, and they are locked to the fixed tabletop according to actual conditions during use.

[0044] The described rotating assembly includes a flange 17, a rotating shaft 16 embedded in the groove of the flange 17, a bushing 13 inserted into the mounting hole of the support 11, a support plate 18 connected to the flange 17 by a screw one 24, a washer 20 and a large nut 12 arranged on the rotating shaft 16. The rotating assembly is fixedly assembled with the support 11 through the large nut 12 and the washer 20, and the rotating assembly can rotate freely and flexibly in the support assembly.

[0045] The utility model restricts the axial displacement of the rotating shaft 16 through the screw one 24 and controls the circumferential position of the rotating shaft 16 through the cylindrical pin two 28.

[0046] The described support plate 18 is L-shaped, and the support plate 18 is connected to the flange 17 by a screw one 24.

[0047] The described flange 17 is provided with a positioning hole for installing the rotating shaft 16, and a cylindrical pin two 28 is arranged on the positioning hole.

[0048] The described rotating shaft 16 is a stepped shaft, including a shaft section one 30 for locking the large nut 12, a shaft section two 31 and a shaft section three 32 for installing in the bushing 13 and being able to rotate freely and smoothly, a shaft section five 34 installed in the groove of the flange 17, and a shaft section six 35 connected to the shaft section five 34. Six shaft positioning holes 36 for realizing angle control are evenly distributed on the circumference of the shaft section three 32.

[0049] The bushings 13 are installed face to face in the mounting holes of the support 11 to prepare for the installation of the rotating shaft 16.

[0050] The outer diameter of the shaft section five 34 is larger than the outer diameters of all shaft sections. After installation, pin holes are configured on the flange 17 according to the existing through holes on the shaft section five 34 to realize the synchronous rotation of the flange 17 and the rotating shaft 16.

[0051] Adjust the rotational performance of the adjusting mechanism and tighten the large nut 12 to prevent the rotating assembly from axially moving.

[0052] The clamping assembly includes an upper clamp 37 and a lower clamp 39 that are pinned together through a cylindrical pin three 38, rubber pads 40 provided on the inner surfaces of the upper clamp 37 and the lower clamp 39, and quick clamps 41 provided on the upper clamp 37 and the lower clamp 39.

[0053] The angle control assembly includes a positioning pin one 14 that fixes the bearing seat 11 to the shaft positioning hole 36 of the rotating shaft 16, and a positioning pin two 15 that fixes the bearing seat 11 to the flange 17.

[0054] The upper clamp 37 can be flipped 240 degrees around the cylindrical pin three 38. The rubber pads 40 are vulcanized on the inner surfaces of the upper clamp 37 and the lower clamp 39 to prevent the rubber pads from falling off due to the corrosion of aviation fuel. The length of the pull rod of the quick clamp 41 is adjustable, and the workpiece is clamped and positioned by pressing the handle of the quick clamp 41.

[0055] The tightening method of the upper clamp 37 and the lower clamp 39 is changed from the original form of a round nut combined with a lever to a quick clamp type, which is more time-saving and labor-saving and convenient to operate under the condition of meeting the clamping force.

[0056] The positioning pin one 14 realizes angle control at 0°, 60°, 120°, 180°, 240°, 300°, and 360°.

[0057] The positioning pin two 15 realizes angle control at ±90°.

[0058] The positioning pin one 14 and the positioning pin two 15 are in a basic hole system fit with the hole φ6H7 / g6. The maximum clearance is 0.024 mm, and the minimum clearance is 0.004 mm.

[0059] The present utility model reserves a 90° flipping station through the positioning pin one 14 and the positioning pin two 15 and is positioned by the support plate 18, which is convenient to operate.
