Description

Technical Field

[0001] This utility model relates to the field of motor gasket testing technology, specifically a device for testing the hardness of motor gaskets. Background Technology

[0002] Motor gasket hardness testing devices are key tools for motor quality control, and their selection must consider the gasket material characteristics, testing accuracy requirements, and production scenarios. For example, insulating gaskets in precision motors require micro-level indentation testing using a micro Vickers hardness tester, while rubber gaskets in general-purpose motors can be quickly screened using a portable Shore hardness tester. Accurate hardness testing ensures that gaskets provide stable mechanical support, insulation, or sealing functions in the motor, improving overall motor reliability and lifespan. However, hardness testing typically requires testing different locations on the gasket surface. Current technologies for testing different locations on the gasket surface usually involve rotating a disc using precision components such as a motor, reducer, indexing plate, transmission gears, and guide rails. This requires sophisticated installation and commissioning techniques, as well as a lubrication system, which can lead to environmental pollution. Furthermore, the meshing of gears generates noise, contributing to noise pollution.

[0003] A hardness testing device for motor gaskets is proposed to address the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a hardness testing device for motor gaskets, so as to solve the problem mentioned in the background art. In the current technology, when testing the hardness of different positions on the surface of the gasket, the rotation of the rotating disk is usually achieved by setting up precision components such as motor, reducer, indexing plate, transmission gear, and guide rail. However, the installation and debugging requirements are high, and a lubrication system is also required, which may cause environmental pollution. At the same time, the meshing between gears will generate noise, which will also cause noise pollution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hardness testing device for motor gaskets, comprising a fixed column, wherein an operating table is fixedly mounted on one side surface of the fixed column near the bottom;

[0006] A connecting plate is fixedly installed on one side of the top surface of the fixed column, and a linear guide rail is fixedly installed on one side surface of the connecting plate. The side surface of the linear guide rail away from the connecting plate is fixedly connected to the fixed column, and a sliding sleeve is connected through the surface of the linear guide rail.

[0007] Also includes:

[0008] The operating table has a groove inside, and a rotating component is installed inside the groove;

[0009] The rotating assembly includes a mounting bracket that is fixedly connected to the groove;

[0010] An extension plate is fixedly connected to one side of the mounting bracket near the center.

[0011] Preferably, a motor is fixedly mounted on the top surface of the extension plate, a first pulley is connected through the top surface of the motor output end, a belt is attached to the surface of the first pulley, and a second pulley is attached to the surface of the belt away from the first pulley.

[0012] Preferably, a rotating rod is fixedly connected to the bottom surface of the second pulley, the bottom surface of the rotating rod is rotatably connected to the fixed frame, and a connecting rod is fixedly connected to the middle of the top surface of the second pulley.

[0013] Preferably, a cylinder is fixedly installed in the middle of the bottom surface of the sliding sleeve, and a detection device is fixedly installed on the bottom surface of the cylinder.

[0014] Preferably, a rotating disk is attached to the top surface of the operating table, and a connecting rod is fixedly connected to the bottom surface of the rotating disk.

[0015] Preferably, a circular column is fixedly installed in the middle of the top surface of the rotating disk, and a plurality of placement slots are opened inside the circular column. An electric push rod is fixedly installed inside the placement slot, and a top plate is fixedly connected to the side surface of the electric push rod away from the placement slot.

[0016] Preferably, the top plate is made of rubber.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This hardness testing device for motor gaskets, by setting a rotating component, makes it easier to install and debug the rotating component while driving the rotating disk to rotate. It also makes maintenance of the belt, first pulley, and second pulley more convenient. Furthermore, the belt, first pulley, and second pulley are inexpensive, thus reducing the increase in costs to a certain extent. The specific details are as follows:

[0018] 1. By setting up a rotating assembly, after the hole in the gasket passes through the circular cylinder, the electric push rod and the top plate cause the top plate to fit against the inner wall of the hole in the gasket, thus stabilizing the gasket. After stabilizing the gasket, the hardness of the gasket can be tested through the cooperation between the cylinder and the detection device. When testing different positions of the gasket, the motor is started via the operating table, so that the output of the motor drives the rotation of the first pulley. The rotation of the first pulley drives the rotation of the belt, which in turn drives the rotation of the second pulley. The rotation of the second pulley drives the rotation of the rotating rod and the connecting rod. The rotation of the connecting rod, in turn, drives the rotation of the rotating disk, which in turn drives the rotation of the gasket. By controlling the motor speed, the rotating disk and gasket rotate with a buffer, allowing the detection device to detect different positions on the gasket surface. Furthermore, the belt, first pulley, and second pulley are relatively inexpensive, thus reducing the overall cost increase. The rotating assembly, composed of the belt, first pulley, and second pulley, also makes installation, debugging, and maintenance more convenient.

[0019] 2. By setting up a rotating disk, a circular column, a groove, an electric push rod, and a top plate, after the hole in the middle of the gasket passes through the circular column, the bottom of the gasket fits against the rotating disk. Simultaneously, when the diameter of the hole in the middle of the gasket is larger than the diameter of the circular column, the electric push rod is activated via the operating table. This causes the output end of the electric push rod to move the top plate, making it fit against the inner wall of the hole, thus providing a stable fit. Furthermore, the top plate is made of rubber, which prevents wear on the gasket surface when the top plate compresses the inner wall of the hole. It also serves to inspect gaskets of different sizes.

[0020] 3. By setting up a connecting plate, linear guide rail, sliding sleeve, cylinder, and detection device, when detecting the surface of gaskets of different sizes, the linear guide rail is activated by the operating table, causing the output end of the linear guide rail to drive the sliding sleeve to move. The movement of the sliding sleeve causes the cylinder and detection device to move to the appropriate position. Then, the cylinder is activated by the operating table, causing the output end of the cylinder to drive the detection device to descend, so that the bottom of the detection device contacts the gasket, thereby achieving the purpose of the detection device to detect the hardness of the gasket.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a hardness testing device for motor gaskets, including a fixed column 1, an operating platform 2 fixedly mounted on one side of the fixed column 1 near the bottom; a connecting plate 3 fixedly mounted on one side of the top surface of the fixed column 1, a linear guide rail 4 fixedly mounted on one side of the connecting plate 3, the side of the linear guide rail 4 away from the connecting plate 3 fixedly connected to the fixed column 1, and a sliding sleeve 5 penetrating the surface of the linear guide rail 4; further comprising: a groove 9 formed inside the operating platform 2, and a rotating assembly 10 disposed inside the groove 9; wherein the rotating assembly 10 includes a fixed frame 1001 fixedly connected to the groove 9; wherein an extension plate 1002 is fixedly connected to the side of the fixed frame 1001 near the middle, such as Figure 1-5 As shown, by setting the rotating component 10, it is possible to drive the rotating disk 8 to rotate, and the installation and debugging of the rotating component 10 are more convenient. At the same time, it is also more convenient to maintain the belt 1005, the first pulley 1004 and the second pulley 1006. In addition, the belt 1005, the first pulley 1004 and the second pulley 1006 are inexpensive, which can reduce the increase in cost to a certain extent. The linear guide 4 is model LAM33-A.

[0029] A motor 1003 is fixedly mounted on the top surface of the extension plate 1002. A first pulley 1004 is connected through the top surface of the output end of the motor 1003. A belt 1005 is attached to the surface of the first pulley 1004. A second pulley 1006 is attached to the side of the belt 1005 away from the first pulley 1004. A rotating rod 1007 is fixedly connected to the bottom surface of the second pulley 1006. The bottom surface of the rotating rod 1007 is rotatably connected to the fixed frame 1001. A connecting rod 1008 is fixedly connected to the middle of the top surface of the second pulley 1006. Figure 4 As shown, when detecting different positions of the gasket, the operating table 2 starts the motor 1003, causing the output of the motor 1003 to drive the rotation of the first pulley 1004. The rotation of the first pulley 1004 drives the rotation of the belt 1005, which in turn drives the rotation of the second pulley 1006. The rotation of the second pulley 1006 then drives the rotation of the rotating rod 1007 and the connecting rod 1008. Simultaneously, the rotation of the connecting rod 1008 drives the rotation of the rotating disk 8. The rotation of the rotating disk 8 drives the rotation of the gasket. Simultaneously, by controlling the speed of the motor 1003, the rotating disk 8 and the gasket rotate with buffer, allowing the detection device 7 to detect different positions on the surface of the gasket. Furthermore, the belt 1005, the first pulley 1004, and the second pulley 1006 are relatively inexpensive, which reduces the increase in cost to a certain extent. Moreover, the rotating assembly 10, composed of the belt 1005, the first pulley 1004, and the second pulley 1006, makes installation, debugging, and maintenance more convenient.

[0030] A cylinder 6 is fixedly mounted in the middle of the bottom surface of the sliding sleeve 5, and a detection device 7 is fixedly mounted on the bottom surface of the cylinder 6, such as... Figure 1 As shown, the detection device 7 is existing technology and its working principle is the same as that of existing technology.

[0031] A rotating disk 8 is attached to the top surface of the operating table 2, and a connecting rod 1008 is fixedly connected to the middle of the bottom surface of the rotating disk 8. Figure 3 , 4 As shown, the connecting rod 1008 is fixedly connected to the rotating disk 8, so that when the connecting rod 1008 rotates, it can drive the rotating disk 8 to rotate, thereby driving the gasket to rotate.

[0032] A circular column 11 is fixedly installed in the center of the top surface of the rotating disk 8. Several placement slots 12 are formed inside the circular column 11. An electric push rod 13 is fixedly installed inside each placement slot 12. A top plate 14 is fixedly connected to the side of the electric push rod 13 away from the placement slot 12. The top plate 14 is made of rubber. Figure 5 As shown, by setting up a rotating disk 8, a circular column 11, a groove 9, an electric push rod 13, and a top plate 14, after the hole in the middle of the gasket passes through the circular column 11, the bottom of the gasket fits against the rotating disk 8. At the same time, when the diameter of the hole in the middle of the gasket is larger than the diameter of the circular column 11, the electric push rod 13 is activated through the operating table 2, so that the output end of the electric push rod 13 drives the top plate 14 to move, thereby making the top plate 14 fit against the inner wall of the hole, thus providing a stable effect for the hole. At the same time, the top plate 14 is made of rubber, which prevents wear on the surface of the gasket when the top plate 14 is squeezed against the inner wall of the hole, and also has the function of detecting gaskets of different sizes.

[0033] Working principle: Before using this hardness testing device for motor gaskets, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 5 As shown, firstly, by setting the rotating assembly 10, after the circular column 11 passes through the hole in the gasket, the electric push rod 13 and the top plate 14 cause the top plate 14 to fit against the inner wall of the hole in the gasket, thereby stabilizing the gasket. After stabilizing the gasket, the hardness of the gasket can be tested through the cooperation between the cylinder 6 and the detection device 7. When testing different positions of the gasket, the operating table 2 starts the motor 1003, so that the output end of the motor 1003 can drive the first pulley 1004 to rotate. The rotation of the first pulley 1004 drives the belt 1005 to rotate. The rotation of the belt 1005 drives the second pulley 1006 to rotate. The rotation of wheel 1006 drives the rotation of rotating rod 1007 and connecting rod 1008. Simultaneously, the rotation of connecting rod 1008 drives the rotation of rotating disk 8, which in turn drives the rotation of the gasket. By controlling the speed of motor 1003, the rotating disk 8 and gasket rotate with buffer, allowing the detection device 7 to detect different positions on the gasket surface. Furthermore, the relatively low price of belt 1005, first pulley 1004, and second pulley 1006 reduces costs to some extent. The rotating assembly 10, composed of belt 1005, first pulley 1004, and second pulley 1006, facilitates installation, debugging, and maintenance.

[0034] Secondly, by setting up a rotating disk 8, a circular column 11, a groove 9, an electric push rod 13, and a top plate 14, after the hole in the middle of the gasket passes through the circular column 11, the bottom of the gasket fits against the rotating disk 8. At the same time, when the diameter of the hole in the middle of the gasket is larger than the diameter of the circular column 11, the electric push rod 13 is activated through the operating table 2, so that the output end of the electric push rod 13 drives the top plate 14 to move, thereby making the top plate 14 fit against the inner wall of the hole, thus providing a stabilizing effect on the hole. At the same time, the top plate 14 is made of rubber, which prevents wear on the surface of the gasket when the top plate 14 is squeezed against the inner wall of the hole, and also has the function of detecting gaskets of different sizes.

[0035] Finally, by setting up the connecting plate 3, linear guide rail 4, sliding sleeve 5, cylinder 6 and detection device 7, when detecting the surface of gaskets of different sizes, the linear guide rail 4 is activated by the operating table 2, so that the output end of the linear guide rail 4 drives the sliding sleeve 5 to move. Through the movement of the sliding sleeve 5, the cylinder 6 and detection device 7 are moved to the appropriate position. Then, the cylinder 6 is activated by the operating table 2, so that the output end of the cylinder 6 drives the detection device 7 to descend, so that the bottom of the detection device 7 contacts the gasket, thereby achieving the purpose of the detection device 7 to detect the hardness of the gasket.
