Abstract
Description
Technical Field
[0001] This utility model relates to the field of push rod motor testing, specifically, to a push rod motor life testing device. Background Technology
[0002] A linear actuator motor is a device that converts electrical energy into linear motion mechanical energy. It is widely used in many fields such as industrial automation, smart homes, medical equipment, and automobile manufacturing. In industrial automated production lines, linear actuator motors can be used for material pushing and tooling fixture positioning; in smart homes, they can be used to control the opening and closing of curtains and the raising and lowering of smart furniture; in medical equipment, they can be used for raising and lowering operating tables and adjusting medical beds; and in automobiles, they can be used for adjusting seats and automatically opening the trunk.
[0003] However, existing push rod motor life testing equipment only performs a tensile test on the push rod during the testing process, and the push rod motor will shake during the test, which makes the test dangerous. Moreover, it cannot test multiple push rod motors and needs to be improved. Therefore, we propose a push rod motor life testing equipment. Utility Model Content
[0004] This utility model proposes a life testing device for push rod motors.
[0005] The technical solution of this utility model is as follows: A push rod motor life testing device includes a base, a bracket fixedly connected to the top of the base, a concave plate fixedly connected to the top of the base, a spring fixedly connected to the bottom and top of the inner wall of the concave plate, a blocking block fixedly connected to the end of the spring away from the concave plate, a push rod motor disposed inside the concave plate, an anti-sway mechanism disposed inside the bracket, the anti-sway mechanism including a first clamping plate fixedly connected to the inner side wall of the concave plate, a second clamping plate fixedly connected to the inner side wall of the concave plate, a hollow plate fixedly connected to the inner side wall of the bracket, a motor penetrating through the front side of the hollow plate, a threaded rod fixedly connected to the end of the output shaft of the motor, a threaded block threadedly connected to the circumferential surface of the threaded rod, a fixing plate fixedly connected to the side of the threaded block, a connecting plate fixedly connected to the side of the fixing plate away from the threaded block, a concave block fixedly connected to the rear side of the connecting plate, and a third clamping plate fixedly connected to the rear side of the concave block.
[0006] A fourth clamping plate is fixedly connected to the rear side of the concave block, a limit rod is fixedly connected to the inner side wall of the hollow plate, and an electronic measuring instrument is provided on the side of the concave plate. The design of the fourth clamping plate is conducive to further clamping the push rod motor and avoiding shaking during the detection process.
[0007] The side sections of the first clamping plate, the second clamping plate, the third clamping plate, and the fourth clamping plate are all set to be semi-circular. The purpose of the above design is to prevent the push rod motor from shaking during the testing process, so as to avoid injury to the staff and damage to the testing equipment.
[0008] The threaded block is slidably connected to the circumferential surface of the limiting rod, and the side section of the fixing plate is set to L-shape. The above design is conducive to enabling the threaded block to make linear motion.
[0009] The top of the blocking block is provided with an adjustable weight-adding mechanism, which includes a limiting plate. The limiting plate is fixedly connected to the top of the blocking block, and a sliding plate is slidably connected to the inner side wall of the limiting plate. The sliding plate contains a weight-adding block. The design of the weight-adding block is beneficial to reducing the resistance of the adjustable push rod motor during the upward process.
[0010] The sliding plate has a groove at the bottom of its inner wall, and a gripping plate is slidably connected to the inner side wall of the groove. A contact plate is fixedly connected to the bottom of the gripping plate. This design makes it easier for workers to remove the weight-adding blocks.
[0011] The side section of the grip plate is concave, and the weight block is in contact with the inner side wall of the grip plate. This design helps to enhance the stability of the weight block.
[0012] The contact plate contacts the bottom of the sliding plate, and the design of the contact plate helps to prevent the weight block from detaching from the inside of the grip plate during the upward movement.
[0013] The working principle and beneficial effects of this utility model are as follows:
[0014] 1. This utility model uses the driving force of a motor to drive components such as a first clamping plate, a second clamping plate, a third clamping plate, a fourth clamping plate, a threaded rod, a threaded block, a fixing plate, a limiting rod, a connecting plate, and a concave block to cooperate with each other. This enables the motor, which runs through the front and side of the hollow plate, to start, thereby driving the threaded rod fixed to the output shaft to rotate. The rotation of the threaded rod causes the threaded block, which is threaded to the circumferential surface, to move linearly on the circumferential surface of the limiting rod. During the testing of the push rod motor, this prevents the push rod motor from shaking, avoiding damage to personnel and testing equipment. At the same time, it can test multi-rod push rod motors.
[0015] 2. This utility model, through the cooperation of components such as a limiting plate, a sliding plate, a weighting block, a slide groove, a gripping plate, and a contact plate, enables the adjustment of resistance during the testing of a push rod motor. When the operator needs to increase the resistance, they pull the gripping plate sliding on the inner wall of the slide groove upwards, and at the same time, place the weighting block inside the gripping plate. During the testing of the push rod motor, different resistance levels can be tested. It is highly practical but needs further improvement.
[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0026] Example 1
[0027] like Figures 1-6As shown, this embodiment proposes a push rod motor life testing device, including a base 1, a bracket 2 fixedly connected to the top of the base 1, a concave plate 3 fixedly connected to the top of the base 1, a spring 4 fixedly connected to the bottom and top of the inner wall of the concave plate 3, a blocking block 5 fixedly connected to the end of the spring 4 away from the concave plate 3, a push rod motor 6 disposed inside the concave plate 3, and an anti-sway mechanism 7 disposed inside the bracket 2. The anti-sway mechanism 7 includes a first clamping plate 71, which is fixedly connected to the inner side wall of the concave plate 3. A blocking block 5 is fixedly connected to the inner side wall of the concave plate 3. The second clamping plate 72 and the inner wall of the bracket 2 are fixedly connected to a hollow plate 73. A motor 74 passes through the front side of the hollow plate 73. A threaded rod 75 is fixedly connected to the end of the output shaft of the motor 74. A threaded block 76 is threadedly connected to the circumferential surface of the threaded rod 75. A fixing plate 78 is fixedly connected to the side of the threaded block 76. A connecting plate 79 is fixedly connected to the side of the fixing plate 78 away from the threaded block 76. A recess 710 is fixedly connected to the rear side of the connecting plate 79. A third clamping plate 711 is fixedly connected to the rear side of the recess 710.
[0028] A fourth clamping plate 712 is fixedly connected to the rear side of the concave block 710, and a limit rod 77 is fixedly connected to the inner side wall of the hollow plate 73. An electronic measuring instrument 9 is provided on the side of the concave plate 3. The design of the fourth clamping plate 712 is conducive to further clamping the push rod motor 6 and avoiding shaking during the detection process.
[0029] The side sections of the first clamping plate 71, the second clamping plate 72, the third clamping plate 711, and the fourth clamping plate 712 are all set to be semi-circular. The purpose of the above design is to prevent the push rod motor 6 from shaking during the testing process, so as to avoid injury to the staff and damage to the testing equipment.
[0030] The threaded block 76 is slidably connected to the circumferential surface of the limiting rod 77, and the side section of the fixing plate 78 is set to L-shape. The above design is conducive to enabling the threaded block 76 to make linear movements.
[0031] In this embodiment, when the push rod motor 6 needs to be tested, the operator places the push rod motor 6 inside the concave plate 3, so that the output end of the push rod motor 6 contacts the bottom of the blocking block 5, and at the same time, the circumferential surface of the push rod motor 6 contacts the inner walls of the first clamping plate 71 and the second clamping plate 72. At this time, the operator starts the motor 74 that passes through the front side of the hollow plate 73, thereby driving the threaded rod 75 fixed to the output shaft to rotate. The rotation of the threaded rod 75 drives the threaded block 76 threaded to the circumferential surface to move linearly on the circumferential surface of the limiting rod 77. When the threaded block 76 moves linearly, it drives the fixing plate 78 on the side of the threaded block 76 to move linearly, and at the same time drives the connecting plate 79 fixed on the other side of the fixing plate 78 to move linearly. When the connecting plate 79 moves linearly, it drives the multiple concave blocks 710 fixed on the rear side to move linearly. At the same time, the movement of the concave blocks 710 drives the third clamping plate 7 on the rear side to move linearly. As the threaded rod 75 continues to rotate, the third clamping plate 711 and the fourth clamping plate 712 continuously move and contact the circumferential surface of the push rod motor 6, thus completing the clamping of the push rod motor 6 to prevent shaking. After clamping is completed, the operator starts the push rod motor 6, causing the blocking block 5 to slide upward on the inner wall of the concave plate 3. At the same time, the spring 4 fixed to the top of the inner wall of the concave plate 3 is in a taut state. When the blocking block 5 is in a suitable position, the push rod motor 6 stops pushing the blocking block 5 upward. At this time, the electronic meter 9 set on the side of the concave plate 3 displays the pushing force. After standing still for several minutes, the operator reverses the motor 74 so that the third clamping plate 711 and the fourth clamping plate 712 no longer contact the push rod motor 6. The operator then takes out the push rod motor 6 for internal testing. If it operates normally, it meets the usage standards, thus testing the service life of the push rod motor 6.
[0032] Example 2
[0033] like Figures 1-6 As shown, based on the same concept as in Embodiment 1 above, this embodiment also proposes that the top of the blocking block 5 is provided with an adjustable weight-adding mechanism 8. The adjustable weight-adding mechanism 8 includes a limiting plate 81, which is fixedly connected to the top of the blocking block 5. A sliding plate 82 is slidably connected to the inner side wall of the limiting plate 81. A weight-adding block 83 is provided inside the sliding plate 82. The design of the weight-adding block 83 is beneficial to the resistance of the adjustable push rod motor 6 during the upward process.
[0034] The inner wall of the sliding plate 82 has a groove 84 at the bottom, and a grip plate 85 is slidably connected to the inner side wall of the groove 84. A contact plate 86 is fixedly connected to the bottom of the grip plate 85. The above design makes it easier for staff to remove the weight block 83.
[0035] The side section of the grip plate 85 is set to be concave, and the weight block 83 is in contact with the inner side wall of the grip plate 85. The above design helps to enhance the stability of the weight block 83.
[0036] The contact plate 86 contacts the bottom of the sliding plate 82. The design of the contact plate 86 helps to prevent the weight block 83 from detaching from the inside of the grip plate 85 during the upward movement.
[0037] In this embodiment, when the resistance of the push rod motor 6 needs to be adjusted during the testing process, if the operator needs to increase the resistance, the operator pulls the grip plate 85 sliding on the inner wall of the slide groove 84 upwards, and at the same time places the weight-adding blocks 83 inside the grip plate 85, thereby increasing the weight of the blocking block 5. When it is necessary to reduce the weight of the blocking block 5, the operator pulls the grip plate 85 upwards again, and then pulls out several weight-adding blocks 83, thereby reducing the weight of the blocking block 5.
[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
