Description

Technical Field

[0001] This invention relates to a multifunctional bracket with an adjustable angle, belonging to the technical field of adjustable angle brackets. Background Technology

[0002] After aerospace components are machined, their flat surfaces need to be inspected. When an aerospace component has one right angle and multiple inclined surfaces, a fixed-angle V-block (see Chinese Patent Publication No. CN115371556B, the wedge groove set in the rear main unit) is used to place the aerospace component. Since the angle of the fixed-angle V-block cannot be adjusted, only one inclined surface of the aerospace component can be in a horizontal state for inspection. There is a problem that it is not possible to rotate multiple inclined surfaces to a horizontal state for inspection. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a multifunctional bracket with adjustable angle.

[0004] The present invention is achieved through the following technical solutions.

[0005] The present invention provides a multi-functional adjustable angle bracket, comprising: A base in a fixed state; A support block is rotatably mounted on the base, and the support block can rotate on the base with the aerospace components to adjust the angle.

[0006] The base has fixing through holes on both sides.

[0007] The base has an arc-shaped opening with a boss fixed inside; it also includes a support block with a groove on its outer periphery. The support block has two mutually perpendicular reference surfaces, and the two reference surfaces are recessed into the support block to form a V-shaped groove. The groove of the support block and the boss of the base can slide together.

[0008] Both the groove and the boss have T-shaped cross-sections, allowing them to slide relative to each other.

[0009] The support block has circumferentially distributed angle scale bars A on its side; the base has circumferentially distributed angle scale bars B on its side, and the angle scale bars A and B correspond to each other.

[0010] The support block at the root of the intersection of the two reference planes is provided with a relief groove; the support block in the relief groove is provided with an internal locking threaded hole B, which is two spaced-apart internal locking threaded holes B, and an internal locking screw B is screwed into the internal locking threaded hole B. The bottom of the internal locking screw B passes through the groove and presses against the boss to limit the position of the support block.

[0011] The internal locking threaded hole B is provided with a countersunk section to accommodate the head of the internal locking screw B.

[0012] The base has an internal locking threaded hole A on its side top. An internal locking screw A is screwed into the internal locking threaded hole A. The bottom of the internal locking screw A passes through the boss and presses against the groove to limit the position of the support block.

[0013] The beneficial effects of this invention are as follows: When the groove of the support block is rotated on the protrusion of the base for angle adjustment, the locking screw A and the inner locking screw B are first unscrewed and no longer tightened for limiting. The aerospace component rests at a right angle against the two mutually perpendicular reference surfaces of the support block. The support block, carrying the aerospace component, rotates on the base for angle adjustment. At this time, the scale value of the adjusted angle can be seen by the correspondence between the angle scale bar A and the angle scale bar B. After any one of the multiple inclined surfaces on the aerospace component is made to be horizontal, the aerospace component is removed, and the locking screw A and the inner locking screw B are screwed in. The support block is tightened and limited by the inner locking screw A and the inner locking screw B and can no longer rotate with the base at an arc angle. Then, the aerospace component is rested at a right angle against the two mutually perpendicular reference surfaces, and then the horizontal inclined surface is detected. This solves the problem that it is impossible to rotate multiple inclined surfaces to be horizontal for detection. Attached Figure Description

Detailed Implementation

[0015] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0016] like Figures 1 to 5 As shown.

[0017] This application discloses an adjustable-angle multifunctional bracket, comprising: The base 1 has a fixing through hole 11 on both sides, and the fixing bolts fix the base 1 through the fixing through hole 11.

[0018] The base 1 has an arc-shaped opening, and a boss 12 is fixed inside the arc-shaped opening.

[0019] It also includes a support block 2 with a groove 21 on its outer periphery. The support block 2 has two reference surfaces 22 that are perpendicular to each other. The two reference surfaces 22 are recessed into the support block 2 to form a V-shaped groove. The groove 21 of the support block 2 and the boss 12 of the base 1 can slide together. The cross-section of both the groove 21 and the boss 12 is T-shaped, so that the groove 21 and the boss 12 can only slide together relative to each other.

[0020] The support block 2 has circumferentially distributed angle scale bars A23 on its side; the base 1 has circumferentially distributed angle scale bars B13 on its side, and the angle scale bars A23 and B13 correspond to each other.

[0021] The support block 2 at the intersection of the two reference surfaces 22 is provided with a relief groove 24. The relief groove 24 is used to avoid contact with the right-angle end of the aviation component 5. The relief groove 24 can also prevent dust and debris from accumulating and causing contact with the right angle of the aviation component 5. The support block 2 in the relief groove 24 is provided with an internal locking thread hole B25. There are two internal locking thread holes B25 spaced apart. An internal locking screw B3 is screwed into the internal locking thread hole B25. The bottom of the internal locking screw B3 passes through the groove 21 and is pressed against the boss 12 to limit the support block 2.

[0022] The internal locking threaded hole B25 is provided with a countersunk section to accommodate the head of the internal locking screw B3, so as to prevent the head of the internal locking screw B3 from protruding from the relief groove 24.

[0023] The base 1 has an internal locking threaded hole A on its side top. An internal locking screw A4 is screwed into the internal locking threaded hole A. The bottom of the internal locking screw A4 passes through the boss 12 and presses against the groove 21 to limit the position of the support block 2.

[0024] The support block 2 is tightened and limited by the tightening force of the inner locking screws A4 and B3. At this time, the T-shaped groove 21 and the T-shaped boss 12 cooperate to prevent the base 1 from separating from the support block 2 under force. When the groove 21 of the support block 2 needs to be rotated on the boss 12 of the base 1 for angle adjustment, the locking screws A4 and B3 first unscrew and no longer tighten to limit the position. The aerospace component 5 rests at a right angle against the two mutually perpendicular reference surfaces 22 of the support block 2. The support block 2, carrying the aerospace component 5, rotates on the base 1 to adjust the angle. At this time, the angle can be adjusted by the angle scale bar A. 23 corresponds to the angle scale bar B13 to adjust the angle scale value. After any one of the multiple inclined surfaces 51 on the aviation component 5 is made to be horizontal, the aviation component 5 is removed, and the locking screw A4 and the inner locking screw B3 are screwed in. The support block 2 is tightened and limited by the inner locking screw A4 and the inner locking screw B3 and can no longer rotate with the base 1 at an arc angle. Then the aviation component 5 is placed at a right angle against two mutually perpendicular reference surfaces 22, and then the horizontal inclined surface 51 is tested. This solves the problem that multiple inclined surfaces cannot be rotated to be horizontal for testing.
