Description

Technical Field

[0001] The utility model relates to the technical field of sensor detection, in particular to a speed sensor torque test bench. Background Art

[0002] Speed ​​sensors are the main components for speed monitoring and are widely used in vehicles and other transportation vehicles to ensure their safe operation. At present, contact speed sensors are usually used as common vehicle speed monitoring sensors on the market, that is, the connecting shaft of the speed sensor is connected to the power output structure, and the connecting shaft of the speed sensor is synchronously driven to rotate during the power output process through the power output structure. At this time, the speed sensor is internally provided with a pulse generating component, such as the existing grating and photoelectric sensing structure, etc. The grating can be installed on the connecting shaft, and the photoelectric sensing structure is fixed on the corresponding carrier, so that the connecting shaft can drive the grating to continuously pass through the photoelectric sensing structure when rotating, thereby generating a series of pulse signals, and calculating the linear speed according to the distance value represented by each pulse, thereby meeting the speed monitoring needs.

[0003] In actual use, the connecting shaft is affected by its own installation and the pulse generating components, so it will be subject to resistance when being driven, which will cause negative effects during the operation of the speed sensor, such as excessive heat generation, affecting the monitoring accuracy and service life. Therefore, the speed sensor needs to limit its running resistance. At present, the industry usually detects the running torque of the speed sensor itself. The greater the running torque, the greater the running resistance, and vice versa. However, the industry currently only clamps the connecting shaft of the speed sensor to be tested with a handheld torque wrench and rotates it. The torque of the speed sensor is obtained by the value of the torque wrench to meet the qualified requirements. Although torque detection can be achieved, it requires manual hand-held tools, which has a heavy labor burden. In addition, each time a different speed sensor is clamped, due to the different clamping angles and the direction of the applied force, the detection benchmark of each speed sensor is different, there is a large detection error, and the product uniformity is poor. Summary of the invention

[0004] In view of the above-mentioned problems existing in the prior art, the present invention aims to provide a speed sensor torque test bench, in which an output motor is installed on a frame with a detection table.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 4 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.

[0033] Figure 1 FIG. 1 is a structural diagram of an embodiment of a speed sensor torque test bench of the utility model. Figure 1 As shown, the speed sensor torque test bench provided in this embodiment includes: a workbench 1, a clamping seat 2, an output motor 3, a torque sensor 4, a first connector 5 and a second connector 6.

[0034] Specifically, the workbench 1 includes a frame 11 and a detection table 12. At this time, the frame 11 is stably placed in the processing workshop, and the detection table 12 is horizontally arranged on the top of the frame 11. The detection table 12 provides a larger detection operation platform, which is convenient for operators to detect the speed sensor. At the same time, a detection hole 121 is opened on the detection table 12 and runs through the vertical direction, so that the connecting shaft of the speed sensor 7 to be tested can pass through the detection hole 121 and connect with the torque sensor 4 and the output motor 3, thereby ensuring that most of the structure used for detection can be located below the detection table 12, thereby maintaining the cleanliness of the upper surface of the detection table 12 and facilitating the clamping of the speed sensor 7 to be tested.

[0035] Specifically, the clamping seat 2 is arranged on the detection table 12, and the clamping seat 2 is distributed beside the detection hole 121, so that the speed sensor 7 to be detected placed on the detection table 12 and located at the detection hole 121 can be clamped by the clamping seat 2 later, ensuring that the speed sensor can maintain stability during the detection process, improving the detection accuracy, and making the structural design more reasonable.

[0036] Specifically, the output motor 3 is installed on the workbench 1. At this time, the output motor 3 is located below the detection table 12, which realizes the hiding of the output motor 3, makes more reasonable use of space, and also realizes the protection of the output motor 3. In addition, the output shaft of the output motor 3 is arranged upward in the vertical direction, which provides conditions for the output shaft of the output motor 3 to drive the connecting shaft of the speed sensor 7 to be detected to rotate.

[0037] Specifically, the torque sensor 4 is a double-headed torque sensor 4. At this time, the torque sensor 4 is arranged between the output motor 3 and the detection hole 121, which provides conditions for the subsequent torque detection by connecting the output motor 3 and the speed sensor 7 to be detected through the torque sensor 4. In addition, the two connectors of the torque sensor 4 are arranged in the vertical direction, so that the arrangement direction of the two connectors of the torque sensor 4 is the same as the arrangement direction of the output shaft of the output motor 3 and the connection shaft of the speed sensor 7 to be detected, which facilitates the subsequent connection and power transmission, and the structural design is more reasonable. It is worth pointing out that the double-headed torque sensor 4 is a commonly used torque detection sensor on the market. In this embodiment, a suitable type of sensor can be selected according to actual use requirements for purchase and installation. In addition, the existing torque sensor 4 usually has an output wire and a display device connected by the output wire, which can intuitively reflect the torque size detected by the current torque sensor 4, and facilitate detection. In addition, since the torque sensor 4 and the display device are commonly used structures on the market and are widely used, their specific structures are not repeated here.

[0038] Specifically, the first connector 5 is installed between the output motor 3 and the connector at one end of the torque sensor 4. At this time, the output shaft of the output motor 3 and the connector at one end of the torque sensor 4 are connected to each other through the first connector 5, so that the output motor 3 can drive the torque sensor 4 to rotate, providing conditions for subsequently driving the speed sensor 7 to be detected to rotate.

[0039] Specifically, the second connector 6 is installed on the connecting head at the other end of the torque sensor 4, and the end of the second connector 6 facing away from the torque sensor 4 is arranged toward the detection hole 121, so that when the detection is carried out later, the connecting shaft of the speed sensor 7 to be detected passes through the detection hole 121 and is connected with the end of the second connector 6 arranged toward the detection hole 121, thereby realizing the connection between the torque sensor 4 and the speed sensor 7 to be detected, thereby realizing the connection between the output motor 3, the torque sensor 4 and the speed sensor 7 to be detected, which can not only drive the speed sensor 7 to be detected to run through the output motor 3, but also detect the torque during operation through the torque sensor 4. Subsequently, by comparing the detected torque with the standard torque predetermined by the design, it is determined whether the speed sensor to be detected meets the manufacturing standards.

[0040] Figure 2This is a structural diagram of the auxiliary mounting frame of a table in a preferred embodiment of the utility model. Figure 1 and Figure 2 As shown, in addition to the frame 11 and the detection table 12 mentioned above, the workbench 1 is also provided with an auxiliary mounting frame 13. Moreover, the auxiliary mounting frame 13 includes a mounting plate 131 and a vertical plate 132. During installation, one end of the vertical plate 132 is fixed on the mounting plate 131 and arranged in a mutually perpendicular state, so that the mounting plate 131 and the vertical plate 132 can form an approximately "L"-shaped structure. When the auxiliary mounting frame 13 is subsequently installed on the detection table 12, the side of the mounting plate 131 facing away from the vertical plate 132 is attached to the bottom surface of the detection table 12 and is locked on the detection table 12 by bolts, thereby realizing the stable installation of the auxiliary mounting frame 13 on the detection table 12. At the same time, the vertical plate 132 is arranged vertically downward, and the output motor 3 and the torque sensor 4 are fixedly installed on the vertical plate 132, that is, the vertical plate 132 provides a stable installation carrier for the output motor 3 and the torque sensor 4, so that the output motor 3 and the torque sensor 4 can be arranged in sequence in the vertical direction, which facilitates the installation of the output motor 3 and the torque sensor 4.

[0041] More specifically, a reinforcing plate 133 is also provided between the mounting plate 131 and the vertical plate 132. At this time, the reinforcing plate 133 is a structure with a right-angled triangle arrangement on one side. During installation, the two mutually perpendicular edges of the reinforcing plate 133 are fixedly connected to the mounting plate 131 and the vertical plate 132, respectively. That is, the reinforcing plate 133 provides auxiliary support for the connection between the installation and the column, improves the structural strength, makes the auxiliary mounting frame 13 more stable, and has a stronger bearing capacity, thereby better maintaining the stability of the output motor 3 and the torque sensor 4 in the detection structure, and ensuring the detection accuracy. It is worth pointing out that the mounting plate 131 and the vertical plate 132, the reinforcing plate 133 and the vertical plate 132, and the reinforcing plate 133 and the mounting plate 131 are all welded connections, which are easy to process and have higher connection strength.

[0042] Figure 3 This is a structural diagram of a detection platform of a preferred embodiment of the utility model. Figure 1 and Figure 3As shown, a plurality of positioning holes 122 are provided on the detection platen 12 of the workbench 1 and are located beside the detection hole 121. At this time, the distribution positions of the plurality of positioning holes 122 on the detection platen 12 relative to the detection hole 121 are consistent with the distribution positions of the plurality of mounting holes on the speed sensor 7 to be detected relative to its connecting axis, and a positioning column 123 extending vertically upward is installed in each positioning hole 122, so that when the speed sensor 7 to be detected is subsequently clamped on the detection platen 12, the positioning column 123 can be directly inserted into the mounting hole to realize the positioning of the speed sensor 7 to be detected, which facilitates the loading and unloading operations, and also ensures that each speed sensor 7 to be detected can maintain the same detection state, thereby ensuring the uniformity of the product.

[0043] More specifically, the clamping seat 2 is set to a plurality of quick-release presser feet. At this time, the plurality of quick-release presser feet are distributed beside the detection hole 121 in a circular array with the axis of the detection hole 121, so that the arrangement of the plurality of quick-release presser feet beside the detection hole 121 is realized, and the uniform distribution of the quick-release presser feet beside the detection hole 121 is also realized, so that the speed sensor 7 to be detected which is restricted by the positioning column 123 can be quickly pressed by the pressure rod of the quick-release presser foot later, and the problem of looseness during the detection process is prevented, and the detection accuracy is improved. In addition, the loading and unloading operations are also facilitated, and the force uniformity of the speed sensor 7 to be detected is maintained. It is worth pointing out that the quick-release presser foot is a presser foot commonly used in tooling fixtures and can be directly purchased and installed, so its specific structure is not repeated here.

[0044] More specifically, the first connector 5 for connecting the output motor 3 and the torque sensor 4 and the second connector 6 for connecting the torque sensor 4 and the speed sensor 7 to be detected both include a coupling 51, which makes the connection more convenient and the adaptability better.

[0045] Figure 4 FIG. 1 is a structural diagram of a second connector of a preferred embodiment of the utility model. Figure 1 and Figure 4 As shown, in addition to the above-mentioned coupling 51, the second connector 6 also includes an auxiliary mounting seat 61, a mating head 62 and an adapter head 63. The auxiliary mounting seat 61, the mating head 62 and the adapter head 63 can adapt to the connection requirements of speed sensors of different models, thereby improving the adaptability of the test bench.

[0046] More specifically, one side of the auxiliary mounting seat 61 is fixedly mounted on the vertical plate 132, and the other end of the auxiliary mounting seat 61 extends horizontally to the bottom of the detection hole 121, and a through hole arranged in the vertical direction is opened on the extended end of the auxiliary mounting seat 61. Preferably, the through hole is coaxially arranged with the detection hole 121 in the vertical direction. At the same time, a support bearing 611 is installed in the through hole, which provides conditions for the subsequent installation of the mating head 62, and also provides conditions for the subsequent mating head 62 to be directly opposite the connecting shaft of the speed sensor 7 to be detected in the vertical direction, thereby preventing the subsequent mating head 62 and the adapter head 63 from completely requiring the torque sensor 4 to bear the weight and causing an external burden on the torque sensor 4, thereby ensuring that the torque sensor 4 is affected as little as possible by the external environment and further improving the detection accuracy.

[0047] More specifically, the mating head 62 further includes a first connection flange 621 and a rotating shaft 622. At this time, the rotating shaft 622 is arranged in the vertical direction, and the upper end of the rotating shaft 622 is fixedly connected to the center of the first connection flange 621. Preferably, the rotating shaft 622 and the first connection flange 621 are an integrated structure. At the same time, the lower end of the rotating shaft 622 passes through the support bearing 611 and then extends downward, so that the rotating shaft 622 can be supported by the support bearing 611, which not only realizes the installation of the mating head 62, but also meets the subsequent use requirements of following the rotation of the torque sensor 4. In addition, the end of the rotating shaft 622 extending downward is connected to the coupling 51 of the second connector 6, so as to realize the connection between the mating head 62 and the torque sensor 4, and meet the power transmission and torque detection requirements.

[0048] More specifically, the adapter head 63 further includes a second connection flange 631 and a rotating sleeve 632. When installed, the rotating sleeve 632 is arranged in the vertical direction, and the lower end of the rotating sleeve 632 is fixedly connected to the center of the second connection flange 631. It is also preferred that the rotating sleeve 632 and the second connection flange 631 are an integrated structure with higher structural strength. In addition, the rotating sleeve 632 is coaxially arranged with the detection hole 121, and the upper end of the rotating sleeve 632 is arranged toward the detection hole 121, which is convenient for subsequent connection with the connecting shaft of the speed sensor 7 to be detected. In addition, the second connection flange 631 is connected to the first connection flange 621 by bolts, so as to realize the connection between the mating head 62 and the adapter head 63, and the connecting shaft of the speed sensor 7 to be detected is inserted into the upper end of the rotating sleeve 632, so as to realize the connection between the adapter head 63 and the connecting shaft of the speed sensor 7 to be detected. In addition, the rotating sleeve 632 can be directly plugged and connected with the connecting shaft of the speed sensor 7 to be detected, which is more convenient for connection, loading and unloading, and improving the detection efficiency. It is worth pointing out that when testing different types of speed sensors, they can be adapted by replacing the adapter head 63 of the rotating sleeve 632 with different inner diameters, which has higher structural flexibility and improves the utilization rate of the test bench.

[0049] More specifically, a plurality of moving wheels 14 are further provided at the bottom of the frame 11. At this time, the plurality of moving wheels 14 are evenly distributed on the frame 11. The moving wheels 14 improve the mobility of the workbench 1, thereby facilitating the transportation of the test bench.

[0050] More specifically, a plurality of legs 15 are provided at the bottom of the frame 11. At this time, the plurality of legs 15 are evenly distributed on the frame 11. Preferably, one leg 15 corresponds to one moving wheel 14, so that every part of the frame 11 that can be supported by the moving wheel 14 can be supported by the legs 15. Therefore, when the workbench 1 needs to be moved, it can be supported and moved by the moving wheels 14, and when stable detection is required, it can be supported by the legs 15, thereby meeting the placement requirements in different scenarios.

[0051] More specifically, at least one of the plurality of moving wheels 14 is a locking moving wheel 14, which facilitates temporary positioning during movement and improves safety. In addition, each leg 15 is a lifting leg 15, so that when it is necessary to switch the moving wheel 14 or the leg 15 support, it can be achieved by adjusting the height of the lifting leg 15. It is worth pointing out that the locking moving wheel 14 and the lifting leg 15 are both commonly used structures on the market and can also be directly purchased and installed. Therefore, their specific structures are not described here in detail.

[0052] The speed sensor torque test bench provided in this embodiment includes a workbench 1, a clamping seat 2, an output motor 3, a torque sensor 4, a first connector 5 and a second connector 6; the clamping seat 2 is provided beside the detection hole 121 of the detection table 12 of the workbench 1 to clamp the speed sensor 7 to be detected, and the output motor 3 and the torque sensor 4 are provided below the detection table 12, and the output motor 3 and the torque sensor 4 as well as the torque sensor 4 and the connecting shaft of the speed sensor 7 to be detected are respectively connected through the first connector 5 and the second connector 6, the speed sensor 7 to be detected is driven to run by the output motor 3, and the torque size during the test is detected by the torque sensor 4, which can not only reduce the heavy workload caused by the detection personnel holding the detection tool for detection, but also ensure the uniformity of the position and state of each speed sensor 7 to be detected during detection, ensure the consistency of the detection benchmark, make the detection accuracy higher, and the product uniformity better.

[0053] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
