Specifically, a slide rail consistent with the movement direction of the telescopic rod 22 is provided on the base 10. The telescopic rod 22 can push the push plate 40 to slide in a limited position in the slide rail.

[0040] Specifically, when the product to be tested is fixed on the product station 11, when the telescopic rod 22 is extended, the sensing device abutment 21 abuts against the first sensing device 30, and at the same time, the push plate 40 is pushed to move toward the product to be tested, so that the thrust output end 42 pushes the product to be tested. At the same time, the first sensing device 30 collects the first thrust information of the sensing device abutment 21 acting on the thrust input end 41.

[0041] Specifically, when the calibration sensing component 50 is fixed on the product station 11, during the extension of the telescopic rod 22, the sensing device abutment 21 abuts against the first sensing device 30, and at the same time, the push plate 40 is pushed toward the calibration sensing component 50 to achieve the thrust output end 42 pushing the calibration sensing component 50.

[0042] Furthermore, based on the first thrust information and the second thrust information, an error value of the thrust acting on the product to be tested can be calculated, and the error value can be used to guide the adjustment of thrust detection data of the thrust detection device, thereby making the thrust detection of the thrust detection device more accurate.

[0043] The present application sets a stepless pressure regulating device 80 and a speed regulating device 90 connected to the cylinder, which can realize precise regulation of the cylinder air pressure and the extension and retraction speed; a first sensing device is set between the abutment of the sensing device and the thrust input end, and a detachable calibration sensing component is set on the product work station, which can accurately obtain the actual thrust value acting on the product to be tested.

[0044] In the embodiment of the present application, the first sensing device 30 is fixedly connected to the thrust input end 41. Specifically, the fixed connection method of the first sensing device 30 and the thrust input end 41 includes but is not limited to screw connection, clamping connection and adhesive connection.

[0045] For some examples, see Figure 3 A sensing device mounting member 44 is fixedly disposed on the thrust input end 41 , and the sensing device mounting member 44 and the thrust input end 41 are fixedly connected by fasteners; the sensing device mounting member 44 matches the first sensing device 30 and is used to fix and install the first sensing device 30 .

[0046] In some other embodiments, the first sensing device 30 is fixedly connected to the sensing device abutment 21 , and the fixed connection method between the first sensing device 30 and the sensing device abutment 21 includes but is not limited to screw connection, clamping connection, and adhesive connection.

[0047] In the embodiments of this application, please refer to Figure 2 The thrust detection device also includes a controller 70, which is electrically connected to the first sensing device 30 and the calibration sensing component 50 respectively; the controller 70 is used to receive the first thrust information and the second thrust information, and determine the thrust calibration value according to the first thrust information and the second thrust information, the thrust calibration value represents the thrust difference value corresponding to the first thrust information and the second thrust information, and is used to indicate the difference information between the first thrust value and the actual thrust value acting on the product to be tested, and the first thrust value is obtained based on the first thrust information.

[0048] Specifically, the controller 70 includes but is not limited to a plc controller.

[0049] In some embodiments, the controller 70 is used to determine the first thrust value based on the first thrust information, determine the second thrust value based on the second thrust information, and determine the thrust calibration value based on the first thrust information and the second thrust information. Specifically, the thrust calibration value is the absolute value of the difference between the first thrust value and the second thrust value, representing the difference between the first thrust value and the actual thrust value acting on the product to be tested.

[0050] In some embodiments, due to the influence of the push plate 40 and other related components, the second thrust is at least the combined force of the first thrust, the gravity of the push plate 40, and the friction between the push plate 40 and other related components. Specifically, the second thrust value is greater than the first thrust value. Therefore, the first thrust collected by the first sensing device 30 is not the actual thrust acting on the product to be tested.

[0051] In the embodiments of this application, please refer to Figure 1 and Figure 2 The thrust detection equipment includes a human-machine interaction display device 60, which is electrically connected to a controller 70; the controller 70 is also used to determine the actual thrust value acting on the product to be tested based on the first thrust value and the thrust calibration value, and send the actual thrust value acting on the product to be tested to the human-machine interaction display device 60.

[0052] In some embodiments, when the thrust detection device is initially used, the calibration sensing component 50 is fixed on the product station 11. When the telescopic rod 22 is extended, the first sensing device 30 collects and sends the first thrust information to the controller 70, and the calibration sensing component 50 collects and sends the second thrust information to the controller 70. The controller 70 determines the thrust calibration value based on the first thrust information and the second thrust information. In this way, the thrust calibration value is obtained. After the thrust calibration value is obtained, the calibration sensing component 50 is removed.

[0053] When it is necessary to perform thrust detection on the product to be tested, the product to be tested is fixed on the product station 11. During the extension of the telescopic rod 22, the first sensing device 30 collects and sends first thrust information to the controller 70. The controller 70 determines a first thrust value based on the first thrust information, and calculates an actual thrust value acting on the product to be tested based on the first thrust value and a previously determined thrust calibration value. In this way, the actual thrust value used on the product to be tested can be accurately obtained. The controller 70 sends the actual thrust value acting on the product to be tested to the human-computer interaction display device 60. In this way, real-time display of the actual thrust value acting on the product to be tested is achieved.

[0054] Specifically, the actual thrust value acting on the product to be tested is the sum of the first thrust value currently obtained and the previously determined thrust calibration value.

[0055] The thrust detection equipment of the present application sets a first sensing device between the sensing device abutment and the thrust input end, sets a detachable calibration sensing component on the product workstation, and sets a controller 70 electrically connected to the first sensing device 30 and the calibration sensing component 50 respectively, and sets a human-computer interaction display device 60 electrically connected to the controller 70, which can accurately obtain the actual thrust value acting on the product to be tested and display it in real time through the human-computer interaction display device 60.

[0056] In the embodiments of this application, please refer to Figure 1 A product positioning device 12 is provided on the base 10 , and the product positioning device 12 is slidably connected to the base 10 .

[0058] In the embodiments of this application, please refer to Figure 4The calibration sensing assembly 50 includes a fixedly connected second sensing device 51 and a station connection seat 52; the station connection seat 52 and the product station 11 are detachably connected, and the second sensing device is used to collect the second thrust information of the thrust output terminal 42.

[0059] In some embodiments, the second sensing device 51 includes a second pressure sensor.

[0060] In some embodiments, the station connection base 52 is matched and fixed to the product station 11 , and is used to fix the second sensing device 51 to the product station 11 .

[0061] In some embodiments, the appearance of the station connection seat 52 is consistent with the appearance of the product to be tested, and the station connection seat 52 is fixed to the product station 11 by the product positioning device 12 .

[0062] Specifically, the fixed connection method between the second sensing device 51 and the workstation connection seat 52 includes but is not limited to screw connection, clamping connection and adhesive connection.

[0063] Specifically, the second sensing device 51 collects the second thrust information of the thrust output terminal 42 acting on the calibration sensing component 50, and sends the second thrust information to the controller 70, so that the controller 70 can determine the second thrust value based on the second thrust information.

[0064] In the embodiments of this application, please refer to Figure 3 The thrust input end 41 is provided with a cylinder limiting structure 43, and the cylinder limiting structure 43 is used to limit the upper limit of the movement of the cylinder 20 relative to the push plate 40 in a direction away from the push plate 40.

[0065] In some embodiments, the cylinder limiting structure 43 is symmetrically arranged on both sides of the sensing device abutment 21, and the cylinder limiting structure 43 is fixedly connected to the thrust input end 41. Specifically, the cylinder limiting structure 43 is fixedly connected to the thrust input end 41 through a fastener; a limiting head end is arranged at one end of the sensing device abutment 21 close to the push plate 40, and the limiting head end is accommodated in the cylinder limiting structure 43. The cylinder limiting structure 43 is used to limit the upper limit of movement of the limiting head end in a direction away from the push plate 40 relative to the cylinder limiting structure 43, thereby limiting the upper limit of movement of the telescopic rod 22 in a direction away from the push plate 40 relative to the push plate 40, so that in the process of retracting the telescopic rod 22, the telescopic rod 22 can drive the push plate 40 to move away from the product station 11.

[0066] Furthermore, during the retraction of the telescopic rod 22, there is a preset gap between the limit head end and the first sensing device 30 in the moving direction of the telescopic rod 22, so that the sensing device abutment member 21 is released from abutting the first sensing device 30. Specifically, the first preset gap may be 1 mm.

[0067] In the embodiment of the present application, the stepless pressure regulating device 80 includes a proportional valve.

[0068] For some examples, see Figure 2 The thrust detection device further includes a directional control valve 100, which is connected to the cylinder 20 and is used to control the movement direction of the cylinder 20. Specifically, the directional control valve 100 includes a solenoid valve. A proportional valve is arranged between the solenoid valve and the cylinder 20 and is used to steplessly adjust the air pressure of the cylinder 20, so as to achieve stepless and precise adjustment of the output thrust of the telescopic rod 22.

[0069] In the embodiment of the present application, the controller 70 is electrically connected to the stepless voltage regulating device 80, and the human-machine interactive display device 60 displays an adjustment control for the control parameters of the stepless voltage regulating device 80. In this way, by manipulating the adjustment control, the control parameters of the stepless voltage regulating device 80 can be visually adjusted, and the operation convenience is good.

[0070] In the embodiment of the present application, the cylinder 20 includes a rod chamber, and the speed regulating device 90 includes a first exhaust throttle valve, which is connected to the rod chamber and is used to adjust the extension speed of the cylinder 20. Specifically, the extension speed of the telescopic rod 22 is adjusted by exhaust throttling of the rod chamber, so that the inaccurate detection of the actual thrust value acting on the product to be tested due to the excessive extension speed of the telescopic rod 22 can be avoided, thereby improving the accuracy of thrust detection of the thrust detection device.

[0071] In some embodiments, the cylinder 20 includes a rodless chamber, and the speed regulating device 90 includes a second exhaust throttle valve, which is connected to the rodless chamber and is used to adjust the retraction speed of the cylinder 20. Specifically, the retraction speed of the telescopic rod 22 is adjusted by exhaust throttling of the rodless chamber.

[0072] In other embodiments, the speed control device 90 includes a first exhaust throttle valve and a second exhaust throttle valve, the first exhaust throttle valve is connected to the rod cavity, and the second exhaust throttle valve is connected to the rodless cavity, the first exhaust throttle valve is used to adjust the extension speed of the telescopic rod 22, and the second exhaust throttle valve is used to adjust the retraction speed of the telescopic rod 22.

[0073] The working process of the thrust detection device in the embodiment of the present application is as follows:

[0074] When the thrust detection device is initially used, the calibration sensing component 50 is fixed on the product station 11, and the output thrust and extension speed of the cylinder 20 are controlled by the stepless pressure regulating device 80 and the speed regulating device 90 respectively. During the extension of the cylinder 20, the sensing device abutment 21 abuts against the first sensing device 30, and at the same time, the push plate 40 is pushed toward the calibration sensing component 50 to achieve the thrust output end 42 pushing the calibration sensing component 50. At the same time, the first sensing device 30 collects the first thrust information of the sensing device abutment 21 acting on the thrust input end 41, and sends the first thrust information to the controller 70. The calibration sensing component 50 collects the second thrust information of the thrust output end 42 acting on the calibration sensing component 50, and sends the second thrust information to the controller 70. The controller 70 determines the thrust calibration value based on the first thrust information and the second thrust information, so as to achieve the acquisition of the thrust calibration value. After the cylinder 20 is controlled to drive the push plate 40 to retract to the initial position, the calibration sensing component 50 is removed.

[0075] When it is necessary to perform thrust detection on the product to be tested, the product to be tested is fixed on the product station 11, and the output thrust and extension speed of the cylinder 20 are controlled by the stepless pressure regulating device 80 and the speed regulating device 90 respectively. During the extension of the cylinder 20, the sensing device abutment 21 abuts against the first sensing device 30, and at the same time, the push plate 40 is pushed toward the product to be tested, so that the thrust output end 42 pushes the product to be tested. At the same time, the first sensing device 30 collects the first thrust information of the sensing device abutment 21 acting on the thrust input end 41, and sends the first thrust information to the controller 70. The controller 70 determines the first thrust value currently acquired based on the first thrust information currently acquired, and calculates the actual thrust value acting on the product to be tested based on the first thrust value currently acquired and the previously determined thrust calibration value. Specifically, the actual thrust value acting on the product to be tested is the sum of the first thrust value currently acquired and the previously determined thrust calibration value. In this way, the actual thrust value acting on the product to be tested can be accurately acquired. The control cylinder 20 drives the push plate 40 to retract to the initial position.

[0076] At the same time, the controller 70 sends the actual thrust value acting on the product to be tested to the human-machine interaction display device 60, so that the real-time visual display of the actual thrust value acting on the product to be tested is achieved.

[0077] The thrust detection device in the embodiment of the present application has the following beneficial effects:

A first sensing device is arranged between the sensing device abutment and the thrust input end, a detachable calibration sensing component is arranged on the product station, and a controller is arranged to be electrically connected to the first sensing device and the calibration sensing component respectively, so as to accurately obtain the actual thrust value acting on the product to be tested and improve the accuracy of thrust detection of the thrust detection equipment.

[0085] The thrust detection equipment also includes a directional control valve 100, which is connected to the cylinder 20 and is used to control the movement direction of the cylinder 20; the stepless pressure regulating device 80 is connected to the rodless chamber and is used to steplessly adjust the air pressure in the rodless chamber, thereby steplessly adjusting the output thrust of the cylinder 20, thereby achieving stepless and precise adjustment of the output thrust of the cylinder 20.

[0086] The speed regulating device 90 includes a first exhaust throttle valve and a second exhaust throttle valve, the first exhaust throttle valve is connected to the rod chamber, the second exhaust throttle valve is connected to the rodless chamber, the first exhaust throttle valve is used to adjust the extension speed of the telescopic rod 22, and the second exhaust throttle valve is used to adjust the retraction speed of the telescopic rod 22. Specifically, the extension speed of the telescopic rod 22 is adjusted by exhaust throttling of the rod chamber, and the retraction speed of the telescopic rod 22 is adjusted by exhaust throttling of the rodless chamber. In this way, it is possible to avoid inaccurate detection of the actual thrust value acting on the product to be tested due to excessive extension speed of the telescopic rod 22, thereby improving the accuracy of thrust detection of the thrust detection device.

[0087] The sensing device abutment 21 is arranged at one end of the telescopic rod 22 close to the push plate 40 . The sensing device abutment 21 is fixedly connected to the telescopic rod 22 via a fastener. A limit head end is arranged at one end of the sensing device abutment 21 close to the push plate 40 .

[0088] The base 10 is provided with a slide rail which is consistent with the movement direction of the telescopic rod 22. The telescopic rod 22 can push the push plate 40 to slide in a limited position in the slide rail. The sliding direction of the push plate 40 is consistent with the movement direction of the telescopic rod 22. In this way, the output thrust of the cylinder 20 can be accurately transmitted to the product to be tested.

[0089] A thrust input end 41 is provided at one end of the push plate 40 close to the cylinder 20, and a cylinder limiting structure 43 is provided at the thrust input end 41. The cylinder limiting structure 43 is fixedly connected to the thrust input end 41 by fasteners. The cylinder limiting structure 43 is symmetrically arranged on both sides of the abutment 21 of the sensing device, and the limiting head end is accommodated in the cylinder limiting structure 43. The cylinder limiting structure 43 is used to limit the upper limit of movement of the limiting head end in the direction away from the push plate 40 relative to the cylinder limiting structure 43, thereby limiting the upper limit of movement of the telescopic rod 22 in the direction away from the push plate 40 relative to the push plate 40, so that in the process of retracting the telescopic rod 22, the telescopic rod 22 can drive the push plate 40 to move away from the product station 11.

[0090] During the retraction of the telescopic rod 22 , a preset gap exists between the limit head end and the first sensing device 30 in the moving direction of the telescopic rod 22 , so that the abutment of the sensing device abutment member 21 against the first sensing device 30 is released.

[0091] A sensing device mounting member 44 is fixedly provided on the thrust input end 41, and the sensing device mounting member 44 and the thrust input end 41 are fixedly connected by fasteners; the sensing device mounting member 44 matches the first sensing device 30, and is used to fix the first sensing device 30 on the thrust input end 41, and the first sensing device 30 is used to collect the first thrust information of the sensing device abutment member 21 acting on the thrust input end 41.

[0092] A thrust output end 42 is disposed at one end of the push plate 40 away from the cylinder 20 . The thrust output end 42 is used to push the product to be tested or the calibration sensing component 50 driven by the cylinder 20 .

[0093] A product positioning device 12 is provided on the base 10. The product positioning device 12 matches the shape of the product to be tested, and includes a corresponding lateral positioning device and a longitudinal positioning device. Both the lateral positioning device and the longitudinal positioning device are slidably connected to the base 10. In the process of positioning the product to be tested, the lateral positioning device and the longitudinal positioning device slide relative to the base 10 respectively to clamp the product to be tested, thereby achieving the positioning and fixation of the product to be tested.

[0094] The calibration sensing assembly 50 includes a fixedly connected second sensing device 51 and a station connection seat 52, and the station connection seat 52 is detachably connected to the product station 11; the shape of the station connection seat 52 is consistent with the shape of the product to be tested, and the station connection seat 52 is fixed to the product station 11 through the product positioning device 12. The second sensing device 51 is used to collect the second thrust information of the thrust output terminal 42 acting on the calibration sensing assembly 50.

[0095] The thrust detection device further includes a controller 70 , which is electrically connected to the first sensing device 30 and the second sensing device 51 , respectively.

[0096] The controller 70 is used to receive the first thrust information and the second thrust information, and determine the first thrust value based on the first thrust information, determine the second thrust value based on the second thrust information, and determine the thrust calibration value based on the first thrust information and the second thrust information. Specifically, the thrust calibration value is the absolute value of the difference between the first thrust value and the second thrust value, and is used to indicate the difference information between the first thrust value and the actual thrust value acting on the product to be tested.

[0097] The thrust detection device includes a human-machine interactive display device 60, which is electrically connected to a controller 70; the controller 70 is also used to determine the actual thrust value acting on the product to be tested based on the first thrust value and the thrust calibration value, and send the actual thrust value acting on the product to be tested to the human-machine interactive display device 60. Specifically, the actual thrust value acting on the product to be tested is the sum of the first thrust value currently obtained and the thrust calibration value previously determined.

[0098] The controller 70 is electrically connected to the stepless voltage regulating device 80, and the human-machine interactive display device 60 displays an adjustment control for the control parameters of the stepless voltage regulating device 80. In this way, by manipulating the adjustment control, the control parameters of the stepless voltage regulating device 80 can be visually adjusted, and the operation convenience is good.

[0099] The working process of the thrust detection device in Example 1 is as follows:

[0100] When the thrust detection device is initially used, the calibration sensing component 50 is fixed on the product station 11, and the output thrust and extension speed of the cylinder 20 are controlled by the stepless pressure regulating device 80 and the speed regulating device 90 respectively. During the extension of the cylinder 20, the sensing device abutment 21 abuts against the first sensing device 30, and at the same time, the push plate 40 is pushed toward the calibration sensing component 50 to achieve the thrust output end 42 pushing the calibration sensing component 50. At the same time, the first sensing device 30 collects the first thrust information of the sensing device abutment 21 acting on the thrust input end 41, and sends the first thrust information to the controller 70. The calibration sensing component 50 collects the second thrust information of the thrust output end 42 acting on the calibration sensing component 50, and sends the second thrust information to the controller 70. The controller 70 determines the thrust calibration value based on the first thrust information and the second thrust information, so as to achieve the acquisition of the thrust calibration value. After the cylinder 20 is controlled to drive the push plate 40 to retract to the initial position, the calibration sensing component 50 is removed.

[0101] When it is necessary to perform thrust detection on the product to be tested, the product to be tested is fixed on the product station 11, and the output thrust and extension speed of the cylinder 20 are controlled by the stepless pressure regulating device 80 and the speed regulating device 90 respectively. During the extension of the cylinder 20, the sensing device abutment 21 abuts against the first sensing device 30, and at the same time, the push plate 40 is pushed toward the product to be tested, so that the thrust output end 42 pushes the product to be tested. At the same time, the first sensing device 30 collects the first thrust information of the sensing device abutment 21 acting on the thrust input end 41, and sends the first thrust information to the controller 70. The controller 70 determines the first thrust value currently acquired based on the first thrust information currently acquired, and calculates the actual thrust value acting on the product to be tested based on the first thrust value currently acquired and the previously determined thrust calibration value. Specifically, the actual thrust value acting on the product to be tested is the sum of the first thrust value currently acquired and the previously determined thrust calibration value. In this way, the actual thrust value acting on the product to be tested can be accurately acquired. The control cylinder 20 drives the push plate 40 to retract to the initial position.

[0102] At the same time, the controller 70 sends the actual thrust value acting on the product to be tested to the human-machine interaction display device 60, so that the real-time visual display of the actual thrust value acting on the product to be tested is achieved.

The similarities between Example 2 and Example 1 will not be repeated here, and only the differences between Example 2 and Example 1 will be described.

[0109] The speed regulating device 90 includes a first exhaust throttle valve, which is connected to the rod chamber and is used to adjust the extension speed of the cylinder 20. Specifically, the extension speed of the telescopic rod 22 is adjusted by exhaust throttling of the rod chamber, so that the inaccurate detection of the actual thrust value acting on the product to be tested due to the excessive extension speed of the telescopic rod 22 can be avoided, thereby improving the accuracy of thrust detection of the thrust detection device.
