Description

TECHNICAL FIELD

[0001] The utility model relates to part measuring equipment technical field especially relates to a quick alignment rotatable detection clamp. BACKGROUND

[0002] The hydraulic pipeline connecting piece on aerospace equipment (such as Figure 1 ) is usually connected with the effective connection of the guide pipe (part 4) and (pipe joint) by adopting the conical surface sealing mode, and the flat pipe nozzle (part 3) is the support part of the guide pipe, and the other three parts are connected together tightly by the sleeve nut (part 2). In order to guarantee the reliability of the conical surface sealing, the angle of the conical surface and the size of the corner R must be controlled within the tolerance range. Due to the backward detection technology in the early stage, the measuring mode is that the angle of the conical surface is detected by coloring with the angle gauge, and the size of the corner R is usually guaranteed by the numerical control program processing mode, so that the size of the part cannot be accurately measured. With the progress of science and technology, the profile instrument is currently used to measure the angle of the conical surface and the corner R. But since the profile instrument is a general equipment, for measuring the angle of the conical surface and the size of the corner R of the flat pipe nozzle, the probe moving axis plane of the profile instrument and the axis plane of the flat pipe nozzle must be on a plane, so as to guarantee the accuracy of the measurement data.

[0003] Since the specifications of the flat pipe nozzle are more, a standard series has nearly 20 specifications, as shown in Figure 2 , the characteristic is that the shapes are similar, and the angle of the conical surface and the value of the corner R are measured by the profile instrument;

[0004] The current measurement scheme is that the flat pipe nozzle is clamped by using the flat mouth vice, then the probe contacts the outer circle of the part, and the highest point of the probe on the part is found from front, back, left and right, as shown in Figure 3 . After detecting a kind of specification of the part, the center position of the part changes when measuring another specification, and the center position of the part does not coincide with the center position of the measuring rod (as shown in Figure 4 ), so the center of the part needs to be found again. In the process of aligning the center of the part, the highest point of the probe on the outer circle of the part must be found, and then the angle of the conical surface of the part and the value of R are measured. The problems existing in this process are as follows:

[0005] 1. The detection efficiency is low, and the center section position of the part cannot be quickly aligned;

[0006] 2. The center of the part needs to be aligned again for different specifications of the part;

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0027] like Figure 5As shown, a quick alignment rotatable detection clamp includes a quick alignment assembly and a base mounting assembly, the quick alignment assembly is rotatably fixed on the base mounting assembly around a point, and a contour gauge is installed on the base mounting assembly to quickly determine the center position of different specifications of flat pipe nozzles and complete the clamping of the flat pipe nozzles by the quick alignment assembly, and the rotation cooperation between the quick alignment assembly and the base mounting assembly can solve the detection clamping requirements of different positions.

[0028] The quick alignment assembly will be described in detail below. The quick alignment assembly described above includes a fixed plate 1 and a magnetic V-shaped seat 2 fixedly arranged on the fixed plate 1, and a V-shaped notch symmetrical to the center line of the magnetic V-shaped seat 2 is arranged on the side surface opposite to the rotation direction of the magnetic V-shaped seat 2. Under the premise that the V-shaped notch is a symmetrical structure, the self-centering principle of the V-shaped block can be used, and the magnetic V-shaped seat can fix the part at the V-shaped notch by adsorption, which can prevent the clamping damage to the surface of the flat pipe nozzle part by mechanical fixing.

[0029] A square fixing frame corresponding in size to the magnetic V-shaped seat 2 is arranged in the fixed plate 1, a fixing hole is formed through the side surface of the fixed plate 1, an external thread matched with a bolt is arranged in the fixing hole, and the magnetic V-shaped seat 2 is fixed in the fixing frame by inserting the magnetic V-shaped seat 2 into the fixing frame, inserting the bolt into the fixing hole, and tightening the bolt. A bottom plate 3 fixed below the fixed plate 1 is also included, and the bottom plate 3 and the fixed plate 1 can be combined into one body by bolts.

[0030] The following will be combined Figure 6 The base mounting assembly will be described in detail. The base mounting assembly includes a contour gauge mounting plate 4 and side plates 5 fixed perpendicularly on both sides of the contour gauge mounting plate 4, and the quick alignment assembly is rotatably arranged between the side plates 5. A ring groove 6 is formed in the side plates 5, the ring groove 6 has the rotation shaft as the center, a locking bolt 7 is arranged through the ring groove 6 on the fixed plate 1, and is used to lock the rotation angle of the quick alignment assembly. An adjusting seat 8 and a limiting plate 9 are also arranged on the contour gauge mounting plate 4 as support assemblies to complete the blocking of the movement trend of the quick alignment assembly. The adjusting seat 8 is fixedly arranged on the movement path of the quick alignment assembly, and the limiting plate 9 is arranged at the limit movement position of the quick alignment assembly.

[0031] The rotation function of the aforementioned view line: by loosening the locking bolt 7, the fixed plate 1 and the bottom plate 3 will rotate a certain angle under the action of gravity and the limiting action of the ring groove 6 opened on the side baffle 5. During the rotation process, due to the setting of the adjusting seat 8, the top of the adjusting seat 8 will first contact the lower side of the bottom plate 3, thereby providing support for the bottom plate 3, and the rotation angle can be controlled by the ball head screw screwed into the adjusting seat 8, that is, the adjusting screw screwed into the adjusting seat 8 actually contacts the lower side of the bottom plate 3. After rotating the magnetic V-shaped seat to the appropriate angle, tighten the locking bolt 7 to lock the current state. When rotating to 90 degrees, the adjusting seat 8 is directly removed, at which time the fixed plate 1 and the magnetic V-shaped seat 2 are limited to rotate to the position of 90 degrees by the length limitation of the limiting plate 9 and the ring groove 6, and then the locking bolt 7 is tightened.
