Description

Technical Field

[0001] The utility model relates to the technical field of automated testing, in particular to a spline automatic docking protection device. Background Art

[0002] During the automated production process in the factory, it is often necessary to quickly test the characteristics of the product to ensure production efficiency. When producing automobile motor assemblies, it is necessary to test the various parameters of the motor assembly under specific working conditions. The motor assembly and the test equipment need to complete the spline docking, and then the working condition test is started through the test equipment. However, when the splines are automatically docked, the inner splines and outer splines are in contact at the moment of contact. If the teeth are in contact, there will be interference and the docking will not be successful, resulting in deformation and damage of the inner splines of the test equipment and the outer splines of the test piece, which increases the company's after-sales costs and affects the company's reputation. At the same time, if the inner splines and outer splines fail to dock for many times, the efficiency of the production line will be reduced, increasing the company's production costs. Therefore, we propose a spline automatic docking protection device to solve the above problems. Utility Model Content

[0003] The main purpose of the utility model is to provide a spline automatic docking protection device, which solves the problem that when the splines are automatically docked, if the teeth are in contact with each other, there will be interference and the docking cannot be successful, resulting in deformation and damage of the internal splines of the test equipment and the external splines of the test piece, increasing the company's after-sales costs and affecting the company's reputation. At the same time, if the internal splines and external splines fail to dock successfully for many times, the efficiency of the production line will be reduced, increasing the company's production costs.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A spline automatic docking protection device comprises a bearing seat output flange, the bearing seat output flange is connected to the bearing seat output end of an external testing device through bolts, a spline flange stopper is movably installed inside the bearing seat output flange and at one end close to the testing device, a bearing seat spline flange is movably installed through one end inside the bearing seat output flange and away from the spline flange stopper, the bearing seat spline flange is connected between one end located inside the bearing seat output flange and the spline flange stopper, an induction disk is sleeved on the outer side of the bearing seat spline flange, and a test piece spline sleeve is positioned and installed on the end of the bearing seat spline flange away from the bearing seat output flange through a stopper.

[0006] Preferably, a retaining spring is installed inside the output flange of the bearing seat and at one end close to the testing equipment, and a wave spring is installed inside the output flange of the bearing seat and at one end located between the retaining spring and the spline flange stopper, and the wave spring is respectively connected to the retaining spring and the spline flange stopper.

[0007] Preferably, a threaded hole is provided between the spline flange stopper and the bearing seat spline flange, and bolts are threadedly installed between the overlapping threaded holes.

[0008] Preferably, the induction disc is fixedly connected to the bearing seat spline flange via bolts.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] (1) The utility model utilizes the mechanical properties of the wave spring, and in the non-working state, the wave spring is in a semi-tightened state, pushing the spline flange stopper to be stuck in the hollow bottom of the bearing seat output flange, so that the bearing seat spline flange is in a docking preparation state. During the docking process, when the test piece spline sleeve contacts the test piece spline, the axial thrust of the test piece spline sleeve will be transmitted to the wave spring, compressing it, thereby achieving docking with the test piece spline, thereby improving the overall stability of the test piece spline sleeve and the test piece spline when they are in contact, and also avoiding deformation and damage between the test piece spline sleeve and the test piece spline.

[0011] (2) In the present invention, when the spline sleeve of the test piece and the spline of the test piece are docked, if the docking is unsuccessful, the wave spring will continue to compress, and the proximity switch sensor will detect the position of the induction disk and transmit the signal to the test equipment computer. When the computer detects that the compression of the wave spring is too large, it will determine that the automatic docking of the spline is unsuccessful, and issue a command to let the test equipment return and restart the automatic docking until the spline sleeve of the test piece and the spline of the test piece are successfully docked, thereby improving the overall test efficiency.

[0016] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figures 1 to 3 As shown, an embodiment of the utility model proposes a spline automatic docking protection device, including a bearing seat output flange 1, which is connected to the bearing seat output end of an external test equipment through bolts, and a spline flange stopper 4 is movably installed inside the bearing seat output flange 1 and at one end close to the test equipment, and a bearing seat spline flange 5 is movably installed inside the bearing seat output flange 1 and at one end away from the spline flange stopper 4, and the bearing seat spline flange 5 is connected between one end located inside the bearing seat output flange 1 and the spline flange stopper 4, and an induction disk 6 is installed on the outer side of the bearing seat spline flange 5, and a test piece spline sleeve 7 is installed on the end of the bearing seat spline flange 5 away from the bearing seat output flange 1 through a stopper for positioning.

[0018] like Figure 3 As shown, in another embodiment of the utility model, a retaining spring 2 is installed inside the bearing seat output flange 1 and at one end close to the test equipment, and a wave spring 3 is installed inside the bearing seat output flange 1 and at one end located between the retaining spring 2 and the spline flange stopper 4. The wave spring 3 is respectively connected to the retaining spring 2 and the spline flange stopper 4, and a threaded hole 8 is penetrated between the spline flange stopper 4 and the bearing seat spline flange 5, and bolts are installed between the overlapping threaded holes 8 through threads, and the induction plate 6 is fixedly connected to the bearing seat spline flange 5 by bolts.

[0019] When not in operation, the wave spring 3 is in a semi-compressed state, pushing the spline flange stopper 4 to be stuck in the bottom of the hollow inside the output flange 1 of the bearing seat, so that the spline flange 5 of the bearing seat is in a docking preparation state;

[0020] During operation, the test equipment needs to drive the entire spline docking protection device to rotate at a speed of 5r / min, and push the specimen spline sleeve 7 to dock with the specimen spline through the linear motion mechanism. At the moment of contact, the specimen spline sleeve 7 will be subjected to axial thrust, which is transmitted to the wave spring 3, causing the wave spring 3 to be compressed to buffer the position of the specimen spline sleeve 7, thereby assisting the specimen spline sleeve 7 to dock with the specimen spline;

[0021] Then, during the spline docking process, if the test piece spline sleeve 7 fails to dock with the test piece spline, the wave spring 3 will continue to compress, and the position of the induction disk 6 will be detected by the proximity switch sensor, and the signal will be transmitted to the test equipment computer. If it is found that the wave spring 3 is compressed too much, it means that the automatic spline docking is unsuccessful, and it is necessary to return and restart the automatic docking until the test piece spline sleeve 7 is successfully docked with the test piece spline, which is more convenient.

[0022] The working principle of this spline automatic docking protection device:

[0023] When in use, first when not in operation, the wave spring 3 is in a semi-compressed state, pushing the spline flange stopper 4 to be stuck in the bottom of the hollow inside the output flange 1 of the bearing seat, so that the spline flange 5 of the bearing seat is in a docking preparation state;

[0024] When working, the test equipment needs to drive the entire spline docking protection device to rotate at a speed of 5r / min, and push the specimen spline sleeve 7 to dock with the specimen spline through the linear motion mechanism. At the moment of contact, the specimen spline sleeve 7 will be subjected to axial thrust, which is transmitted to the wave spring 3, causing the wave spring 3 to be compressed to buffer the position of the specimen spline sleeve 7, thereby assisting the specimen spline sleeve 7 to dock with the specimen spline;

[0025] Then, during the spline docking process, if the spline sleeve 7 of the test piece fails to dock with the spline of the test piece, the wave spring 3 will continue to be compressed, and the position of the induction disk 6 will be detected by the proximity switch sensor, and the signal will be transmitted to the test equipment computer. If it is found that the compression of the wave spring 3 is too large, it means that the automatic spline docking is unsuccessful, and it is necessary to return and restart the automatic docking until the spline sleeve 7 of the test piece successfully docks with the spline of the test piece.

[0026] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
