Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and in particular to a fully automatic torsion resistance machine. Background Technology

[0002] In industrial production, especially in consumer electronics, precision instruments, and automotive parts, many core components (such as watch hinges, mobile phone hinges, rotary switches, and miniature valves) rely on stable torsional resistance to function. The accuracy and stability of these torsional resistance parameters directly determine the product's lifespan, handling, and safety. For example, if the torsional resistance of a mobile phone's rotating camera hinge is too low, the lens will rotate on its own during use; if the torsional resistance is too high, it will cause user operation to stall or even damage the hinge structure. Similarly, the consistency of torsional resistance in precision rotary switches in automotive electronics is a key indicator affecting driving safety.

[0003] Current torsional resistance testing equipment on the market generally suffers from the following technical pain points:

[0004] Most equipment requires manual assistance to complete the positioning, clamping and test start of the test piece, which not only leads to low testing efficiency, but also easily affects the repeatability of test data due to human operation errors;

[0005] Traditional equipment can only perform static torsional resistance testing, and cannot simultaneously perform multi-parameter linkage testing of "torsional resistance-angle-speed". It is also difficult to simulate dynamic life test in actual product use scenarios. Multiple devices are required to complete the complete testing process, which increases the equipment investment cost for enterprises.

[0006] Some equipment uses cylinders or ordinary screw drives for the longitudinal drive mechanism, which has problems such as low lifting accuracy and poor operation stability. This makes it difficult to guarantee the coaxiality of the sensing components and the test piece, resulting in torque detection deviation. Utility Model Content

[0007] Therefore, it is necessary to provide a fully automatic torque resistance machine to address the above-mentioned technical problems. The entire process is automated, requiring no manual intervention, and avoiding human error.

[0008] This utility model provides a fully automatic torsion resistance machine, comprising:

[0009] A longitudinal drive unit is mounted on the main base, and an industrial control host is set on one side of the longitudinal drive unit;

[0010] A storage platform is provided on the main base, and the storage platform is located directly below the driving end of the longitudinal drive component;

[0011] A fixture is fixed to the platform and used to fix the part to be tested.

[0012] The sensing component is installed at the drive end of the longitudinal drive member and is located directly above the fixing fixture;

[0013] A rotating assembly is installed at the bottom of the sensing component, and the bottom of the rotating assembly is used to engage with the part to be tested; wherein, the industrial control host is used to record data of each structural component.

[0014] In one embodiment, the longitudinal drive component includes a lead screw top seat, a lead screw base, guide columns, a lead screw support seat, a lead screw body, and a lifting seat; the lead screw base is fixed on the main base, the lead screw top seat is located directly above the lead screw base and connected by two guide columns, the lead screw body is located between the two guide columns, and lead screw support seats are provided on opposite sides of the lead screw base and the lead screw top seat. Both ends of the lead screw body pass through the two lead screw support seats respectively, and the lifting seat is installed on the guide columns and the lead screw body, and the lead screw body is kinetically connected to the lifting seat.

[0015] In one embodiment, a first motor is fixed to the bottom surface of the lead screw top seat. The drive shaft of the first motor and the top end of the lead screw body both pass through the lead screw top seat, and a synchronous pulley is installed at one end of each of them. The two synchronous pulleys are connected by a transmission to drive the lifting seat to move up and down.

[0016] In one embodiment, the sensing assembly includes a sensor bracket, a sensor connecting plate, and a torque sensor; the sensor bracket is fixed on the lifting base, the sensor connecting plate is disposed on the bottom surface of the sensor bracket, and the torque sensor is mounted on the sensor connecting plate.

[0017] In one embodiment, the rotating unit includes a sensor connecting column, a connecting block, and a fork plate; the sensor connecting column is disposed below and connected to the torque sensor, and the fork plate is connected to the bottom end of the sensor connecting column through the connecting block.

[0018] In one embodiment, the storage platform includes a frustum, an angle scale, a gearbox, and a second motor; the frustum is disposed on the main base, the angle scale is located on one side of the frustum, the gearbox is disposed below the frustum, and the second motor is connected to the gearbox for driving the frustum to rotate via the gearbox.

[0020] In one embodiment, the industrial control host is provided with a host housing, and the sensor bracket is provided with a sensor protective cover. The bottom end of the sensor protective cover is connected to the main base, and the side is connected to the host housing.

[0021] The aforementioned fully automatic torsional resistance tester, through the integrated design of the longitudinal drive component, placement platform, fixed fixture, sensing components, rotating unit, and industrial control host, achieves full automation of the entire process of "automatic positioning - automatic clamping - automatic testing - automatic data recording" for the test piece, eliminating the need for manual intervention and avoiding human error. The longitudinal drive component can precisely control the docking distance between the sensing components and the test piece, while the rotating unit drives the test piece to complete the rotation test.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The following is combined with Figures 1 to 4 This invention describes a fully automatic torsion resistance machine.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, a fully automatic torsion resistance machine includes a longitudinal drive component 100, a placement platform 400, a fixing fixture 500, a sensing component 200, and a rotating unit 300. The longitudinal drive component 100 is mounted on a main base 600, and an industrial control host 710 is disposed on one side of the longitudinal drive component 100. The placement platform 400 is disposed on the main base 600 and is located directly below the driving end of the longitudinal drive component 100. The fixing fixture 500 is fixed on the placement platform 400 and is used to fix the workpiece to be tested. The sensing component 200 is mounted on the driving end of the longitudinal drive component 100 and is located directly above the fixing fixture 500. The rotating unit 300 is mounted on the bottom end of the sensing component 200, and the bottom end of the rotating unit 300 is used to engage with the workpiece to be tested. The industrial control host 710 is used to record data of each structural component.

[0032] The aforementioned fully automatic torsional resistance tester, through the integrated design of the longitudinal drive component 100, the placement platform 400, the fixed fixture 500, the sensing component 200, the rotating unit 300, and the industrial control host 710, achieves full automation of the entire process of "automatic positioning - automatic clamping - automatic testing - automatic data recording" for the test piece, requiring no manual intervention and avoiding human error. The longitudinal drive component 100 can precisely control the docking distance between the sensing component 200 and the test piece, the rotating unit 300 drives the test piece to complete the rotation test, the sensing component 200 collects torsional resistance data in real time, and the industrial control host... The 710 simultaneously records multi-dimensional data such as "torsional resistance, rotation angle, and test time," breaking through the limitations of traditional equipment's single-parameter testing. It can complete multiple test tasks such as static torsional resistance, dynamic life, and strong torsional failure in one go, reducing equipment investment costs. The placement platform 400 is located directly below the drive end of the longitudinal drive component 100, and the sensing component 200 is located directly above the fixed fixture 500, ensuring the coaxiality error of each component and avoiding data distortion caused by coaxiality deviation. At the same time, the industrial control host 710 monitors the data of each structural component in real time, which can promptly detect equipment abnormalities.

[0033] like Figure 3 As shown, in one embodiment, the longitudinal drive member 100 includes a lead screw top seat 110, a lead screw base 120, a guide column 130, a lead screw support seat 140, a lead screw body 150, and a lifting seat 170. The lead screw base 120 is fixed on the main base 600. The lead screw top seat 110 is located directly above the lead screw base 120 and is connected by two guide columns 130. The lead screw body 150 is located between the two guide columns 130. A lead screw support seat 140 is provided on the opposite side of the lead screw base 120 and the lead screw top seat 110. The two ends of the lead screw body 150 pass through the two lead screw support seats 140 respectively. The lifting seat 170 is installed on the guide column 130 and the lead screw body 150, and the lead screw body 150 is connected to the lifting seat 170 in a transmission manner.

[0034] Specifically, a transmission structure of "double guide column 130 + ball screw" is adopted. The guide column 130 provides stable guidance support for the lifting seat 170, avoiding deviation or shaking during the lifting process. The ball screw transmission has the advantages of high transmission efficiency and high positioning accuracy. Compared with the traditional cylinder transmission, the longitudinal adjustment accuracy is higher, ensuring that the sensing component 200 is accurately connected with the test piece and reducing detection deviation.

[0035] In one embodiment, a first motor 180 is fixed to the bottom surface of the lead screw top seat 110. The drive shaft of the first motor 180 and the top end of the lead screw body 150 both pass through the lead screw top seat 110, and a synchronous wheel 160 is installed at one end of each of them. The two synchronous wheels 160 are connected by a transmission to drive the lifting seat 170 to lift.

[0036] Specifically, the first motor 180, in conjunction with the synchronous pulley 160, drives the lead screw body 150 to rotate. The synchronous pulley 160 transmission has the characteristics of precise transmission ratio and smooth operation. Compared with direct motor drive, it can avoid the influence of motor speed fluctuation on lead screw rotation, so that the lifting speed deviation of the lifting seat 170 is controlled within a certain range, ensuring the stability of the sensor component 200 when docking with the test piece, and avoiding damage to the test piece or data deviation due to impact.

[0037] In one embodiment, the sensing assembly 200 includes a sensor bracket 210, a sensor connecting plate 220, and a torque sensor 230; the sensor bracket 210 is fixed on the lifting seat 170, the sensor connecting plate 220 is disposed on the bottom surface of the sensor bracket 210, and the torque sensor 230 is mounted on the sensor connecting plate 220.

[0038] Specifically, the sensor bracket 210 is rigidly connected to the lifting seat 170, and the sensor connecting plate 220 provides a stable mounting reference for the torque sensor 230, preventing the sensor from becoming loose or shifting during the test and ensuring the accuracy of torque detection.

[0039] In one embodiment, the rotating unit 300 includes a sensor connecting post 310, a connecting block 320, and a fork plate 330; the sensor connecting post 310 is disposed below and connected to the torque sensor 230, and the fork plate 330 is connected to the bottom end of the sensor connecting post 310 through the connecting block 320.

[0040] Specifically, the fork plate 330 is rigidly connected to the sensor connecting post 310 via the connecting block 320. The opening size of the fork plate 330 can be customized according to the shape of the part under test (such as a knob protrusion or a shaft slot) to avoid slippage during the test and ensure the accuracy of the rotation angle and torsional resistance data.

[0041] like Figure 4 As shown, in one embodiment, the storage platform 400 includes a frustum plate 410, an angle scale mark 420, a gearbox 430, and a second motor 440. The frustum plate 410 is disposed on the main base 600, the angle scale mark 420 is located on one side of the frustum plate 410, the gearbox 430 is disposed below the frustum plate 410, and the second motor 440 is connected to the gearbox 430 for driving the frustum plate 410 to rotate through the gearbox 430.

[0042] Specifically, the second motor 440 drives the frustum plate 410 to rotate through the gearbox 430. The gearbox 430 can achieve multi-level speed adjustment, and the angle scale 420 can intuitively display the rotation angle of the frustum plate 410. Combined with the control of the industrial control host 710, it can accurately realize "fixed angle rotation" or "fixed speed life test" to meet the dynamic testing needs of the product.

[0043] In one embodiment, the fixture 500 includes a blocking bracket 510, a handle 520, and a stop pin 530; the blocking bracket 510 is fixed on the frustum plate 410, the handle 520 is used to install in a designated position, the stop pin 530 is inserted into the handle 520, and both ends of the stop pin 530 are used to engage with the fork plate 330.

[0044] Specifically, the isolation bracket 510 provides rigid support for the test piece, and the handle 520 can press and fix the test piece through a threaded or snap-fit ​​structure. The clamping force can be adjusted by the handle 520 (to adapt to test pieces of different materials, such as plastic parts to avoid damage and metal parts to ensure a firm fixation).

[0045] In one embodiment, the industrial control host 710 is provided with a host housing 720, and the sensor bracket 210 is provided with a sensor protective cover 240. The bottom end of the sensor protective cover 240 is connected to the main base 600, and the side is connected to the host housing 720.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
