Description

Technical Field

[0001] The utility model relates to the field of torque testing equipment, in particular to a torque testing equipment. Background Art

[0002] Torque testing equipment is mainly used to measure and evaluate the mechanical properties of objects under torsion. It is widely used in materials science, mechanical engineering, and automated testing scenarios, and can effectively evaluate the performance and strength of products. Torque testing is mainly based on the sensor of the test equipment, and the accuracy of the sensor will directly affect the test results.

[0003] The existing patent (publication number: CN219200686U) discloses that "the utility model discloses a torque testing device, including a tester, one side of the tester is connected to a fixed frame, both sides of the fixed frame are provided with a first movable groove, one end of the first movable groove is installed with a first reduction gearbox, one side of the first reduction gearbox is installed with a first motor, the other side of the first reduction gearbox is connected with a first threaded screw, the first threaded screw is connected to a first slider, a movable frame is installed on the top of the first slider, the middle part of the movable frame is provided with a second slide groove, and one end of the second slide groove is installed with a second reduction gearbox. The test device can perform torque testing on wrenches of different lengths, can realize automatic pushing of the wrench to apply external force to the wrench, has strong flexibility, does not need to manually push the wrench, and is very simple and convenient to operate. The test device can quickly measure the torque of the wrench, which is convenient for people to use."

[0004] In the process of realizing the present invention, the inventor discovered that the prior art has the following problems: the force applied by the device to the wrench is not perpendicular to the wrench itself, its push plate does not support the wrench to rotate at a large angle, and when the wrench rotates, only one angle of the push plate will act on the wrench, which will cause large wear with long-term use, thereby affecting the measurement accuracy. At the same time, the wrench of the device is directly mounted on the sensor body and lacks a stable mechanism. Any shaking of its position during testing will have an adverse effect on the measurement. With the long-term use of the equipment, its accuracy will inevitably deviate, and its correction work is relatively complicated to implement. Without relying on the equipment, it is difficult to maintain measurement accuracy under manual intervention.

[0005] Therefore, those skilled in the art provide a torque testing device to solve the problems raised in the above background technology. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a torque testing device. The force applied to the wrench by the device is always perpendicular to the wrench itself, which is convenient for conducting experiments. The wrench can be stabilized before measurement to prevent it from shaking during measurement. At the same time, the rotation angle of the device can be manually intervened, and the accuracy can be further improved in combination with the CNC turntable to prevent damage caused by excessive rotation.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a torque testing device, comprising a device main body, a measuring mechanism is provided at the rear side of the upper end of the device main body, the measuring mechanism comprises a measuring body and a motor, a numerically controlled turntable is rotatably provided on the upper end of the measuring body, a sensor is provided at the center of the upper end of the measuring body, a placement plate is fixedly provided at the top of the other side of the numerically controlled turntable, electric telescopic rods are provided at both sides of the placement plate near the edge, side pressure plates are fixedly provided at the output ends of the two electric telescopic rods, a screw rod is rotatably provided at the center of the other side of the upper end of the placement plate, a lower pressure plate is provided with a threaded sleeve around the screw rod, a positioning block is fixedly provided at the lower part of the other side of the numerically controlled turntable, a scale dial is provided on the upper end of the measuring body near the edge of the numerically controlled turntable, and fixed rods are fixedly provided at the front and back of the upper end of the placement plate near the screw rod;

[0008] A limiting mechanism is provided at the edge of the upper end of the measuring mechanism. The limiting mechanism includes a slide groove and a plurality of slots. A slider is provided inside the slide groove for snap-fitting and sliding. An insert is provided at the lower part of the other side of the slider for snap-fitting and sliding.

[0009] Furthermore, a baffle is fixedly provided on the upper end of the measuring mechanism near the edge, and when the placement plate is in the initial position, the baffle is in contact with the placement plate.

[0010] Furthermore, grooves are provided at the center of the front and rear ends of the placement plate, and the two side pressure plates slide along the grooves toward the wrench.

[0011] Furthermore, the upper end of the screw rod is fixedly arranged on the output end of the motor, and the lower pressure plate is slidably sleeved around the two fixed rods.

[0012] Furthermore, a fixing plate is fixedly provided on the upper ends of the two fixing rods, and the motor is provided on the upper ends of the fixing plates.

[0013] Furthermore, when the placement plate is in the initial position, the positioning block is located at the initial position of the scale plate, and the scale plate indicates the rotation angle.

[0014] Furthermore, the slide groove is arc-shaped and is set at the edge of the dial.

[0015] Furthermore, a display screen is provided at the front of the upper end of the device body, a control panel is provided at the other side of the upper end of the device body close to the display screen, and a wrench is provided at the upper end of the measuring mechanism, and one side of the wrench is sleeved around the sensor.

[0016] The utility model has the following beneficial effects:

[0017] 1. The utility model proposes a torque testing device. After the wrench is installed around the sensor, its main body is placed on the upper end of the placement plate. Then the motor can be started. The motor will drive the screw to rotate to make the lower pressure plate press the wrench. Then the two electric telescopic rods are started to push the side pressure plates to the front and back of the wrench main body, so that the wrench can maintain a stable state in subsequent measurements and its position will not fluctuate. Measuring in a stable state can greatly improve the measurement accuracy. Under the precise rotation of the CNC turntable, the force applied to the wrench is always perpendicular to the wrench main body, and its force is more stable. The parameters such as the force magnitude and the rotation angle distance can be recorded to facilitate subsequent calculations.

[0018] 2. The utility model proposes a torque testing device. The CNC turntable of the device can drive the wrench to rotate at a large angle. However, after long-term use, the accuracy of the CNC turntable will inevitably be affected. In order to prevent the situation where the rotation angle is too large due to insufficient accuracy, the slider can be slid in the slide groove. According to the measurement requirements, a suitable position can be selected, and the insert block on the slider is moved down and inserted into the slot. At this time, it cooperates with the CNC turntable. When the placement plate rotates to contact the slider, it stops immediately, which can further improve the measurement accuracy.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a torque testing device, including a device body 3, a measuring mechanism 1 is provided at the rear side of the upper end of the device body 3, a limiting mechanism 6 is provided at the edge of the upper end of the measuring mechanism 1, a display screen 2 is provided at the front of the upper end of the device body 3, a control panel 4 is provided at the other side of the upper end of the device body 3 close to the display screen 2, a wrench 5 is provided at the upper end of the measuring mechanism 1, and one side of the wrench 5 is sleeved around the sensor 103.

[0027] Specifically, the work performed by the measuring mechanism 1 can be controlled through the control panel 4, and the experimental parameters and analysis are displayed on the display screen 2. After the wrench 5 is placed on the measuring mechanism 1, the wrench 5 can be driven to rotate to ensure that the wrench 5 is subjected to a force perpendicular to itself. In order to ensure measurement accuracy, the limiting mechanism 6 can be manually adjusted to limit the measuring mechanism 1 to prevent excessive rotation.

[0028] Reference Figures 1 to 4 The measuring mechanism 1 includes a measuring body 101 and a motor 106. A numerical control turntable 104 is rotatably provided on the upper end of the measuring body 101. A sensor 103 is provided at the center of the upper end of the measuring body 101. A placement plate 109 is fixedly provided at the upper part of the other side of the numerical control turntable 104. Electric telescopic rods 111 are provided on both sides of the placement plate 109 near the edge. The output ends of the two electric telescopic rods 111 are fixedly provided with side pressure plates 110. A screw rod 108 is rotatably provided at the center of the other side of the upper end of the placement plate 109. A lower pressure plate 105 is provided with a threaded sleeve around the screw rod 108. A positioning block 112 is fixedly provided at the lower part of the other side of the numerical control turntable 104. A scale dial 113 is provided at the upper end of the measuring body 101 near the edge of the numerical control turntable 104.

[0029] A baffle 102 is fixedly provided at the edge of the upper end of the measuring mechanism 1. When the placement plate 109 is in the initial position, the baffle 102 contacts the placement plate 109. Grooves are provided at the front and rear ends of the placement plate 109 near the center. The two side pressure plates 110 slide along the grooves toward the wrench 5. Fixed rods 107 are fixedly provided at the front and rear ends of the placement plate 109 near the screw rod 108. The lower pressure plate 105 is slidably sleeved on the two fixed rods 107. The upper end of the screw rod 108 is fixed to the output end of the motor 106. The upper ends of the two fixed rods 107 are fixed with fixed plates. The motor 106 is set at the upper end of the fixed plate. When the placement plate 109 is in the initial position, the positioning block 112 is located at the initial position of the dial 113, and the dial 113 indicates the rotation angle.

[0030] Specifically, after the two electric telescopic rods 111 drive the corresponding side pressure plates 110 to restrict the front and rear main bodies of the wrench 5, when the CNC turntable 104 drives the wrench 5 to rotate through the placement plate 109, the positions of the two side pressure plates 110 will not change. The downward pressure of the lower pressure plate 105 and the two side pressure plates 110 can be suitable for fixing wrenches 5 of various sizes. The setting of the baffle 102 can ensure that after each measurement is completed, the CNC turntable 104 can be accurately rotated back to the initial position to avoid deviation. During the actual measurement process, the rotation accuracy of the CNC turntable 104 can be observed through the dial 113, and adjustments can be made in time when deviation occurs.

[0031] Reference Figure 3 and Figure 4 The limiting mechanism 6 includes a slide groove 601 and a plurality of slots 602. A slider 603 is provided inside the slide groove 601 for sliding engagement. An insert block 604 is provided at the lower portion of the other side of the slider 603 for sliding engagement. The slide groove 601 is arc-shaped and is provided at the edge of the scale plate 113. The upper surface of the slider 603 is located at a level greater than the upper surface of the placement plate 109. The angles of the plurality of slots 602 are consistent, and the angles of the intervals correspond to the scales on the scale plate 113.

[0032] Specifically, in order to ensure that each measurement can be rotated accurately, the slider 603 can be slid to the position of the corresponding scale, and its position will not change after the plug block 604 is inserted. In the automation design, when the placement plate 109 of the CNC turntable 104 needs to contact the slider 603, it will stop rotating immediately.

[0033] Working principle: When the device is in use, one side of the wrench 5 is first sleeved on the sensor 103, and its main body is placed on the placement plate 109. Then the motor 106 can be started, which will move the lower pressure plate 105 downward and press the main body of the wrench 5 through the rotation of the screw rod 108 and the restriction of the two fixing rods 107. Then the front and rear electric telescopic rods 111 on the placement plate 109 are started, which will push the corresponding side pressure plates 110 to clamp the front and rear ends of the wrench 5. This clamping method is suitable for wrenches 5 of different sizes. After the fixation is completed, it can be regulated through the control panel 4 to control the CNC turntable 104 to complete the rotation of the predetermined angle. At this time, the wrench 5 will start to rotate, and the sensor 103 will reflect the test data on the display screen 2 in real time. By observing the position of the positioning block 112 corresponding to the dial 113, it can be judged whether there is any deviation in the rotation of the CNC turntable 104, which is convenient for timely maintenance and adjustment.

[0034] Secondly, in order to further improve the measurement accuracy, the slider 603 is slid along the slide groove 601 to the position of the predetermined rotation angle, and then the insert block 604 on the slider 603 is moved down and inserted into the slot 602. At this time, when the placement plate 109 rotates to contact with the slider 603, it just rotates to the predetermined angle, and stops rotating immediately after contact, thereby further improving the measurement accuracy.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
