[0002] Shaft workpieces have relatively simple structural elements and are easily machined. They primarily support transmission components, transmit torque, and bear loads. The angle between the two planes extending along the shaft is a crucial parameter, crucial for its proper function. Most workpieces have specific requirements for this angle, especially for shaft workpieces, where the significant difference between their axial and radial dimensions makes coaxiality difficult to control during production. Therefore, measuring the angle between the two planes is particularly crucial.

[0003] Currently, shaft workpieces require inspection of the plane angles at both ends before leaving the factory to ensure their quality. However, traditional inspections of plane angles often use a three-dimensional coordinate measuring machine (CMM) or a dial indicator with a base. These complex structures are not only slow and inefficient, but also require a high level of technical expertise from the inspectors.

[0004] Therefore, the present invention is dedicated to providing a tool and a detection system for detecting the plane angle of a shaft workpiece to solve the above technical problems. Utility Model Content

[0037] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] In one embodiment, a tool for detecting the plane angle of a shaft workpiece is described. By setting a shaft sleeve 1 and a positioning sleeve 2, the shaft sleeve 1 and the positioning sleeve 2 cooperate with each other to detect the plane angle at both ends of the shaft workpiece 4. The structure is simple. Moreover, during detection, the user only needs to put the shaft sleeve 1 and the positioning sleeve 2 on the outside of the shaft workpiece 4 and move the positioning sleeve 2. The operation is very convenient and can effectively improve the detection efficiency of the shaft workpiece 4.

[0039] Specifically, see the accompanying drawings Figures 1 to 4 A tool for detecting the plane angle of a shaft workpiece includes a sleeve 1 and a positioning sleeve 2. Each sleeve 1 and the positioning sleeve 2 is provided with a receiving cavity 3. The receiving cavity 3 matches the shaft workpiece 4, allowing the sleeve 1 and the positioning sleeve 2 to be sleeved on the outside of the shaft workpiece 4 through the receiving cavity 3. A limiting portion 11 is provided at one end of the sleeve 1, and a positioning portion 21 is provided at one end of the positioning sleeve 2. The positioning portion 21 is adapted to engage with the limiting portion 11 to allow the positioning sleeve 2 to be detachably mounted on the sleeve 1.

[0040] In addition, a first opening is provided on both the limiting portion 11 and the positioning portion 21. The first opening and the accommodating cavity 3 are interconnected and coaxially arranged, so that the shaft workpiece 4 enters the accommodating cavity 3 through the first opening, thereby sleeve-fitting the positioning sleeve 2 and the shaft sleeve 1 onto the outside of the shaft workpiece 4. Accordingly, when the positioning portion 21 is engaged with the limiting portion 11, the two accommodating cavities 3 are coaxially arranged.

[0041] It should be noted that during the production and processing of the shaft workpiece 4, the plane angles at both ends may exceed the design range, which will cause the shaft workpiece 4 to be unable to be used normally, resulting in unnecessary waste. Therefore, it is very necessary to detect the shaft workpiece 4, that is, to detect the degree of V-shape of the shaft workpiece 4. In the prior art, a three-coordinate measuring machine or a dial gauge with a dial gauge is often used for detection. On the one hand, the use of the three-coordinate measuring machine, the dial gauge, and the dial gauge is relatively complicated, time-consuming and labor-intensive, and requires a high level of user skills. It is also prone to detection errors. On the other hand, the cost of such tools is also relatively high.

[0042] The utility model provides a tool for detecting the plane angle of a shaft workpiece. Only a sleeve 1 and a positioning sleeve 2 are needed to quickly detect the shaft workpiece 4. The cost is low, the operation is convenient, and the accuracy is high. The specific detection principle is as follows: the user first extends one end of the shaft workpiece 4 into the accommodating cavity 3 of the sleeve 1 through the first opening. At this time, the sleeve 1 is sleeved on one end of the shaft workpiece 4, and then the positioning sleeve 2 is sleeved on the other end of the shaft workpiece 4 through its own first opening. The user can continue to push the positioning sleeve to move. If the plane angle at both ends of the shaft workpiece 4 is within the design range, the positioning portion 21 and the limiting portion 11 can be snap-fitted. Similarly, if the plane angle of the shaft workpiece 4 is not within the design range, the positioning portion 21 and the limiting portion 11 cannot be snap-fitted. In addition, in actual use, the user can also first insert one end of the shaft workpiece 4 into the positioning sleeve 2, and then move the sleeve 1 to complete the detection of the shaft workpiece 4.

[0043] In one embodiment, see the accompanying drawings Figure 3 and Figure 4 This embodiment further illustrates a tool for detecting the plane angle of a shaft workpiece. A mounting groove 22 is provided at one end of the locating sleeve 2. The mounting groove 22 forms a positioning portion 21. Accordingly, the first opening of the locating sleeve 2 is formed on the bottom wall of the mounting groove 22. Accordingly, a boss 12 is provided at one end of the shaft sleeve 1. The boss 12 forms a limiting portion 11, and the boss 12 is adapted to engage with the mounting groove 22 to mount the locating sleeve 2 on the shaft sleeve 1. The first opening of the shaft sleeve 1 is provided on the boss 12.

[0044] It is understood that the limiting portion 11 and the positioning portion 21 are not limited to the drawings in the specification. Figure 2 For example, one end of the sleeve 1 is provided with a mounting groove to form a stopper 11, and the first opening of the sleeve 1 is formed on the bottom wall of the mounting groove. Correspondingly, one end of the locating sleeve 2 is provided with a boss to form a positioning portion 21. Similarly, the boss is adapted to engage with the mounting groove to mount the locating sleeve 2 on the sleeve 1, and the first opening of the locating sleeve 2 is provided on the boss. Details will not be described here, as all of them fall within the scope of protection of the present invention.

[0045] Furthermore, two opposite groove edges of the installation groove 22 coincide with the outer surface of the shaft sleeve 1 or the positioning sleeve 2 and are connected to the outside.

[0046] Preferably, a second opening is provided at the end of the sleeve 1 remote from the first opening, and a second opening is also provided at the end of the positioning sleeve 2 remote from the first opening, with the second opening communicating with the accommodating cavity and being coaxially disposed. It will be appreciated that the provision of the second opening allows the shaft workpiece 4 to extend from the sleeve 1 or positioning sleeve 2 through the second opening, making the tool suitable for inspecting shaft workpieces 4 of varying lengths.

[0047] In addition, the inner diameter of the accommodating cavity 3 is slightly larger than the outer diameter of the shaft workpiece 4 , and the difference between the inner diameter of the accommodating cavity 3 and the outer diameter of the shaft workpiece 4 is generally set according to the design range of the plane angle at both ends of the shaft workpiece 4 .

[0048] In one embodiment, this embodiment provides a detection system, including a tool for detecting the plane angle of a shaft workpiece as described in any of the above embodiments, and also including a base (not shown in the figure), a rotating mechanism (not shown in the figure) and a transmission mechanism (not shown in the figure), wherein the rotating mechanism and the transmission mechanism are relatively arranged on the base, the positioning sleeve 2 is installed on the transmission mechanism, and the transmission mechanism is used to drive the positioning sleeve 2 to move to adjust the distance between the positioning sleeve 2 and the rotating mechanism. Correspondingly, the sleeve 1 is installed on the rotating mechanism and is arranged parallel to the base. The rotating mechanism is used to drive the sleeve to rotate so that the accommodating cavity 3 of the sleeve 1 and the accommodating cavity 3 of the positioning sleeve 2 are coaxially arranged.

[0049] It can be understood that when the detection system is in use, in order to facilitate the installation of one end of the shaft workpiece 4 in the sleeve 1, the sleeve 1 can be driven to rotate by the rotating mechanism so that the sleeve 1 is located on the side away from the transmission mechanism. At this time, the first opening of the sleeve 1 will not be affected by the transmission mechanism, so that one end of the shaft workpiece 4 is inserted into the sleeve 1 through the first opening, and then the rotating mechanism is rotated again, so that the accommodating cavity of the sleeve 1 and the accommodating cavity of the positioning sleeve 2 are coaxially arranged, and then the positioning sleeve 2 is driven by the transmission mechanism to move in the direction close to the sleeve 1 to ensure that the positioning sleeve 2 accurately cooperates with the shaft workpiece 4.

[0050] Specifically, the rotating mechanism includes a first motor, a first clamping assembly and a rotating disk. The rotating disk is rotatably arranged on the base. Accordingly, the first clamping assembly is arranged on the rotating disk, and the sleeve 1 is installed on the rotating disk through the first clamping assembly. In addition, the first motor is arranged on the base and is transmission-connected to the rotating disk to drive the rotating disk and the sleeve 1 to rotate.

[0051] Furthermore, the transmission mechanism includes a second motor, a second clamping assembly, a track, and a mounting base. The track is arranged along the extension direction of the base, and the mounting base is movably mounted on the track and disposed opposite the rotating disk. The second clamping assembly is disposed on the mounting base, and the positioning sleeve 2 is mounted on the mounting base via the second clamping assembly. The second motor is in transmission connection with the mounting base to drive the mounting base and positioning sleeve 2 to move relative to the base.

[0052] Generally speaking, the first clamping assembly and the second clamping assembly can be set as an upper half shell, a lower half shell and bolts, one side of the upper half shell is hinged to one side of the lower half shell, and the other side of the upper half shell is fixed to the other side of the lower half shell by bolts, thereby fixing the sleeve 1 to the first clamping assembly and the positioning sleeve 2 to the second clamping assembly.

[0053] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be noted that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be considered as the scope of protection of the present application.
