[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0039] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0042] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] See also Figures 1 to 11 As shown, this example provides a torque test platform for a shift fork dual rotor, which includes a support frame 1, a torque test device 3 for being transmission-connected with the shift fork dual rotor 2 and testing the transmission torque of the shift fork dual rotor 2, and a bearing drive mechanism for driving the shift fork dual rotor 2 to move and making the shift fork dual rotor 2 transmission-connected or disengaged from the torque test device 3, and the torque test device 3 and the bearing drive mechanism are respectively arranged on the support frame 1;

[0044] The carrying and driving mechanism includes a fork double rotor placement plate 41 which is slidably arranged on the support frame 1 and is used to carry the fork double rotor 2, an elastic member 42 which is arranged on the support frame 1 and is used to make the fork double rotor placement plate 41 tend to move toward a side close to the torque testing device 3, and a locking mechanism 43 which is used to keep the fork double rotor placement plate 41 fixed relative to the support frame 1;

[0045] The shift fork dual rotor placement plate 41 includes an initial position and a test position. When the shift fork dual rotor placement plate 41 is in the initial position, the elastic member 42 is in a compressed state, the locking mechanism 43 is in a locked state, and the shift fork dual rotor 2 is disengaged from the torque testing device 3; when the shift fork dual rotor placement plate 41 is in the test position, the elastic member 42 is in an extended state, the locking mechanism 43 is in an unlocked state, and the shift fork dual rotor 2 is transmission-connected to the torque testing device 3.

[0046] Specifically, in this example, there are two bearing drive mechanisms, which are arranged on the left and right sides of the torque test device 3. Since two fork double rotors are used simultaneously in the existing winding equipment (one of the functions is: one can realize forward transmission and the other can realize reverse transmission), the two are also disassembled for repair and maintenance during inspection. In fact, it is also possible to set up one bearing drive mechanism for the torque test platform of the fork double rotor in this example, but in this example, two are preferably set up, so that the two fork double rotors (also often called left fork double rotor and right fork double rotor in the prior art) can be tested, thereby improving the detection efficiency.

[0047] Further, see Figures 1 to 11 As shown, the two bearing drive mechanisms in this example have basically the same structure and the functions they implement. Therefore, in the following, the bearing drive mechanism corresponding to the left fork double rotor and the right fork double rotor corresponding to the right fork double rotor will not be explained separately, but a general introduction will be given. It should be understood that this is feasible.

[0048] In this example, the elastic member 42 is a spring, one end of which is fixed to the support frame 1, and the other end is connected to the fork dual rotor placement plate 41. Furthermore, in this example, the extension direction of the spring is the sliding direction of the fork dual rotor placement plate 41. The spring is in a compressed and force-storing state when the fork dual rotor placement plate 41 is in the initial position, and is in an extended state when the fork dual rotor placement plate 41 is in the test position. In this process, the fork dual rotor placement plate 41 is pushed by the elastic force of the spring and then slides to the test position.

[0049] In this example, the locking mechanism 43 includes a plunger 431 movably arranged on the fork double rotor display plate 41, and a locking hole 432 arranged on the support frame 1 and cooperating with the plunger 431 to achieve locking; specifically, a handle for a person to hold is formed on the upper part of the plunger 431, and the plunger 431 extends in the up and down directions; at the same time, the bearing drive mechanism also includes a plunger connector 44, and the plunger 431 is connected to the fork double rotor display plate 41 through the plunger connector 44.

[0050] Furthermore, if Figure 1-3 as well as Figure 7-9 It can be seen that when the plunger 431 is inserted into the locking hole 432, the fork double rotor display plate 41 is relatively fixed (relative to the support frame 1). At this time, the spring is in a compressed state, and the fork double rotor 2 is separated from the torque test device 3; when a torque test is required, the plunger 431 is manually pulled out and separated from the locking hole 432, thereby achieving unlocking. After the operator removes the external force, the fork double rotor display plate 41 slides toward the direction close to the torque test device 3 under the action of the spring, and finally slides to the test position. At this time, the fork double rotor pulley 21 of the fork double rotor 2 can be aligned with the torque test device The transmission pulley 33 of the test device 3 is meshed with each other, and then the transmission torque of the fork double rotor 2 is tested by the torque testing device 3; and when the test is completed, the operator can hold the plunger 431 and move the fork double rotor display plate 41 to the initial position, and finally insert the plunger 431 into the locking hole 432; in addition, if the aforementioned test is of the transmission torque of the left fork double rotor on the left side, then after the left fork double rotor test is completed, we can operate the right side load-bearing drive mechanism structure in the same way, and realize the transmission torque test of the right fork double rotor, which will not be described in detail here.

[0051] Moreover, in this example, the plunger 431 is wide at the top and narrow at the bottom, the relatively narrow part at the bottom can be used to insert into the locking hole 432, and the relatively wide part at the top can be held by the operator, so it is a dual-purpose device and does not take up space. The setting of the plunger connector 44 fully facilitates the good matching of the plunger 431 and the locking hole 432, and there is no need to change the shape of the plunger 431 too much, which is easy to design and manufacture.

[0052] In this example, the bearing drive mechanism further includes a limiting mechanism 45, and the limiting mechanism 45 can be implemented in the following two ways:

[0053] The first type: the limiting mechanism includes a limiting rod arranged on the side of the shift fork double rotor placement plate close to the torque test device, and a limiting plate cooperating with the limiting rod to stop the shift fork double rotor placement plate at the test position, and the limiting plate is arranged on the support frame; when the shift fork double rotor placement plate is in the initial position, the limiting rod is away from the limiting plate; when the shift fork double rotor placement plate is in the test position, the limiting rod conflicts with the limiting plate; or,

[0054] The second type: the limiting mechanism 45 includes a limiting baffle 451 arranged on the support frame 1, and a limiting column 452 arranged on the limiting baffle 451 and used to stop the fork dual rotor placement plate 41 at the test position; when the fork dual rotor placement plate 41 is in the initial position, the limiting column 452 is away from the fork dual rotor placement plate 41; when the fork dual rotor placement plate 41 is in the test position, the limiting column 452 conflicts with the fork dual rotor placement plate 41.

[0055] like Figure 3 As shown, the second method is selected in this example, and the limit baffle 451 is set between the left and right fork dual rotor placement plates 41 and centered, roughly located directly above the drive pulley 33. The limit column 452 is fixed on the limit baffle 451, and the extension direction of the limit column 452 is parallel to the sliding direction of the fork dual rotor placement plate 41, and the extension direction of the limit baffle 451 is perpendicular to the sliding direction of the fork dual rotor placement plate 41, which can ensure that the fork dual rotor placement plate 41 will not move more than the ideal distance when moving to the test position. The ideal distance is to prevent the engagement of the fork dual rotor pulley 21 of the fork dual rotor 2 and the drive pulley 33 from being squeezed by external force, that is, through the action of the limit mechanism 45, the external force, especially the force of the spring applied to the fork dual rotor placement plate 41 and transmitted to the drive pulley 33, can be eliminated. Through this fine adjustment and design, the error of the torque test device 3 during testing can be avoided. Obviously, if the fork double rotor pulley 31 and the transmission pulley 33 are too tightly fitted due to external force, it will inevitably interfere with the test of the transmission torque.

[0056] In this example, the carrying driving mechanism also includes a sliding mechanism 46, which includes a support block 461 fixedly set on the support frame 1 and formed with a sliding groove, and a sliding rod 462 connected to the fork double rotor placement plate 41 and slidingly set on the sliding groove of the support block 461, and the extension direction of the sliding rod 462 is parallel to the sliding direction of the fork double rotor placement plate 41.

[0057] In this example, the torque testing device 3 includes a driving motor 31, a dynamic torque sensor 32 whose input end is transmission-connected to the driving motor 31, and a driving pulley 33 connected to the output end of the dynamic torque sensor 32 and used for transmission-connected to the fork dual rotor 2. The driving motor 31 and the dynamic torque sensor 32 are respectively arranged on the support frame 1. The above-mentioned dynamic torque sensor 32 can be obtained commercially, and its working principle is not specifically described. The driving motor 31 can be a stepping motor, which provides a certain initial torque (the initial torque can be specifically modified according to different models of fork dual rotors), and the dynamic torque sensor 32 determines whether the transmission torque of the fork dual rotor to be tested is qualified by the difference between the input torque value and the output torque value.

[0058] In this example, the torque test platform of the shift fork dual rotor can also be equipped with an instrument display and control system that are communicatively connected to the dynamic torque sensor 32, and an alarm device. The alarm device can be communicatively connected to the control system, and the alarm device can include multiple signal lights of different colors, which display different colors according to different test data, so that the operator can obtain the test results intuitively.

[0059] In this example, the driving motor 31 , the dynamic torque sensor 32 and the driving pulley 33 are arranged in sequence from bottom to top.

[0060] In this example, the fork double rotor torque test platform also includes a fork double rotor fixing mechanism 5 for fixing the fork double rotor 2, and the fork double rotor fixing mechanism 5 is arranged on the support frame 1 and is located on one side of the fork double rotor placement plate 41. The fork double rotor fixing mechanism 5 can be a commonly used toggle clamp horizontal high arm type clamping device, such as Figure 1 The structure shown in can be commercially available, and its function is to compress the fork double rotor 2 during the test to prevent displacement during the test process and affect the test results. Of course, in other embodiments, other structures can also be used to fix the fork double rotor 2.

[0061] Furthermore, in this example, Figure 4-6 As shown, the shift fork double rotor placement plate 41 in this example is formed with a gap for the shift fork double rotor pulley 21 at the bottom of the shift fork double rotor to pass through, and the contour of the gap can be adapted to the outer contour of the shift fork double rotor 2, and a positioning column is also formed on the shift fork double rotor placement plate 41, and the positioning column can cooperate with the mounting hole of the shift fork double rotor, thereby ensuring the stability of the shift fork double rotor 2 on the shift fork double rotor placement plate 41, especially the stability in the horizontal direction, further ensuring that the shift fork double rotor is tested without slipping or shaking, thereby improving the accuracy of the test values.

[0062] In summary, the present invention is based on the prior art method of testing the transmission torque of the shift fork double rotor by manual judgment, but the manual testing efficiency is low, the reliability of personnel execution is unstable, and there is a problem of misjudgment due to the lack of accurate values; a new torque testing platform for the shift fork double rotor is innovatively provided, and the torque testing platform cooperates with the load-bearing driving mechanism of a specific structure to realize the use of accurate values ​​to judge the transmission condition of the shift fork double rotor after maintenance, especially the torque testing platform also solves the deviations and errors that may exist in the machine testing process. The present invention specifically solves the excellence of the meshing condition of the shift fork double rotor and the transmission pulley, ensuring the meshing test without affecting the test accuracy.

[0063] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
