[0028] like Figures 1 to 5As shown in the figure, this is an embodiment of the present invention, relating to a push-pull force testing device for hardware parts, including a device body 10. The device body 10 includes a base plate 11, a driving mechanism 20, a measuring mechanism 30, and a clamping mechanism 40 respectively mounted on the base plate 11. The driving mechanism 20 is connected to the measuring mechanism 30 and is used to provide driving force to the measuring mechanism 30. The measuring mechanism 30 includes a tension display 31, a push-pull block 50, and a pressure sensor 32. The tension display 31 is electrically connected to the pressure sensor 32. The front side of the push-pull block 50 is connected to the output end of the driving mechanism 20. The pressure sensor 32 is connected to the push-pull block 50 and the clamping mechanism 40 respectively. The clamping mechanism 40 includes a fixed module 60 and a movable module 70. The fixed module 60 includes a fixed block 61 connected to the base plate 11, and the fixed block 61 has a first clamping groove 62 through it. The movable module 70 includes a movable block 71 slidably connected to the base plate 11. The rear side of the movable block 71 is connected to one end of the pressure sensor 32. The movable block 71 has a second clamping groove 72. The second clamping groove 72 is arranged opposite to the first clamping groove 62. The second clamping groove 72 and the first clamping groove 62 are used to clamp the hardware together.

[0029] Specifically, the device body 10 consists of a base plate 11, a drive mechanism 20, a measuring mechanism 30, and a clamping mechanism 40. The mechanisms work together to provide a basic framework for the push-pull force test of hardware parts, making the test process systematic and feasible.

[0030] Furthermore, the drive mechanism 20 includes at least two drive cylinders 21, which are mounted above the base plate 11 and are used to drive the push-pull block 50 to move back and forth. Specifically, the drive mechanism 20 includes at least two drive cylinders 21, which can provide stable and strong driving force. The dual-cylinder design enhances the adaptability of the device to different test force values, ensures sufficient power for the push-pull block 50 to move back and forth, and improves the stability and reliability of the test. The drive cylinders 21 can be existing drive devices such as electric push rods, hydraulic cylinders, or pneumatic cylinders, and their specific structures will not be described in detail here.

[0031] Furthermore, the drive mechanism 20 also includes a mounting bracket 22, through which the output end of the drive cylinder 21 passes and connects to the push-pull block 50. Specifically, the mounting bracket 22 provides stable support and positioning for the drive cylinder 21, ensuring the stability of the drive cylinder 21 when transmitting driving force, reducing test errors caused by structural sway, and improving test accuracy.

[0032] Furthermore, the bottom of the push-pull block 50 is provided with a plurality of push-pull sliders 51, and the push-pull sliders 51 are movably connected to push-pull slide rails 52, which are mounted on the top of the base plate 11. Specifically, the push-pull sliders 51 at the bottom of the push-pull block 50 are movably connected to the push-pull slide rails 52, which effectively reduces frictional resistance, makes the push-pull block 50 move more smoothly, ensures the linearity of its movement, and thus improves the accuracy and stability of force transmission during the test.

[0033] Furthermore, a connecting rod 33 extends from the side of the pressure sensor 32 away from the movable block 71, and the connecting rod 33 is connected to the push-pull block 50. Specifically, the connecting rod 33 extending from the side of the pressure sensor 32 away from the movable block 71 and connecting to the push-pull block 50 ensures that the force transmission is direct and accurate, so that the force value measured by the pressure sensor 32 truly reflects the force applied by the push-pull block 50, thereby improving the accuracy of the measurement results.

[0034] Furthermore, the fixing module 60 also includes a base 63, which is installed on the bottom of the fixing block 61 and fixedly connected to the base plate 11. Specifically, the base 63 is installed on the bottom of the fixing block 61 and fixed to the base plate 11, enhancing the stability of the fixing block 61, preventing the fixing module 60 from shaking during the test, ensuring that one end of the hardware is firmly fixed, and providing a reliable benchmark for the test.

[0035] Furthermore, the top of the fixing block 61 is provided with a plurality of first threaded holes 64, each of which is threadedly connected to a first clamping screw 65. The lower end of the first clamping screw 65 extends into the first clamping groove 62. By rotating the first clamping screw 65, one end of the hardware is clamped in the first clamping groove 62. Specifically, the first threaded holes 64 on the top of the fixing block 61 cooperate with the first clamping screw 65. By rotating the first clamping screw 65, the clamping force and position on one end of the hardware can be flexibly adjusted to adapt to hardware of different sizes and specifications. The operation is convenient and the clamping is firm.

[0036] Furthermore, the movable module 70 also includes a movable slider 73 and a movable guide rail 74. The movable slider 73 is fixed to the bottom of the movable block 71, and the movable guide rail 74 is fixed to the top of the base plate 11 and slides in cooperation with the movable slider 73. Specifically, the sliding cooperation between the movable slider 73 and the movable guide rail 74 of the movable module 70 ensures that the movable block 71 slides smoothly during testing, so that the clamped hardware is subjected to uniform force, avoiding test errors caused by the shaking of the movable block 71, and improving the accuracy of the test results.

[0037] Furthermore, the top of the movable block 71 is provided with several second threaded holes 75, each of which is threadedly connected to a second clamping screw 76. The lower end of the second clamping screw 76 extends into the second clamping groove 72. By rotating the second clamping screw 76, the other end of the hardware is clamped in the second clamping groove 72. Specifically, the second threaded holes 75 on the top of the movable block 71 cooperate with the second clamping screws 76 to flexibly clamp and adjust the other end of the hardware. In conjunction with the fixed module 60, it can adapt to the testing needs of various hardware components and enhance the versatility of the device.

[0038] Furthermore, the device body 10 includes a controller (not shown in the figure), which is connected to a rotary switch 12. The rotary switch 12 is connected to the drive cylinder 21 and is used to control the extension and retraction movement of the drive cylinder 21. Specifically, the controller (not shown in the figure) is connected to the rotary switch 12 to the drive cylinder 21. The controller (not shown in the figure) can accurately set the working parameters of the drive cylinder 21. The rotary switch 12 can be used as an input component, generating a signal through rotation. After receiving the signal, the controller (not shown in the figure) outputs corresponding instructions to the control valve or power source of the drive cylinder 21 (such as a pneumatic cylinder, hydraulic cylinder, electric push rod, etc.), realizing flexible control of the extension and retraction movement of the drive cylinder 21 (such as starting, stopping, adjusting speed or force, etc.), meeting different test conditions, and improving the automation and convenience of testing. In industrial testing devices, the controller is a common component of centralized control systems.

[0039] The working principle of this utility model is as follows:

[0040] The drive cylinder 21 is fixed above the base plate 11 by the mounting bracket 22, and its output end is connected to the push-pull block 50 through the side wall of the mounting bracket 22. When the drive cylinder 21 is started, it outputs driving force to push or pull the push-pull block 50. The push-pull slider 51 at the bottom of the push-pull block 50 moves smoothly on the push-pull slide rail 52 to ensure the linearity of the movement. The push-pull block 50 drives the pressure sensor 32 through the connecting rod 33. The pressure sensor 32 converts the real-time measured force value into an electrical signal and transmits it to the tension display 31 for display. One end of the hardware is placed in the first clamping groove 62 of the fixed block 61 and is firmly clamped by rotating the first clamping screw 65; the other end is placed in the second clamping groove 72 of the movable block 71 and is stably clamped by rotating the second clamping screw 76. The movable slider 73 at the bottom of the movable block 71 slides in cooperation with the movable guide rail 74 above the base plate 11. When the drive cylinder 21 drives the push-pull block 50 to move, the movable block 71 slides smoothly, thereby applying a push-pull force to the hardware. Meanwhile, the operator can precisely control the extension and retraction of the drive cylinder 21 through the controller (not shown in the figure) and the rotary switch 12, and flexibly set parameters such as test force and speed to meet the diverse push and pull force test requirements of different hardware parts.

[0041] This invention achieves efficient collaboration among its components through a rational structural design. The drive mechanism 20 provides stable and adjustable power, the measuring mechanism 30 accurately captures force information, the clamping mechanism 40 flexibly adapts to hardware parts of different specifications, and the cooperation between the slider, slide rail, and guide rail ensures smooth and stable movement. The controller (not shown in the figure) and rotary switch 12 enhance the convenience and automation of operation. Overall, this invention significantly improves the accuracy, stability, versatility, and ease of operation of push-pull force testing for hardware parts, efficiently meeting diverse push-pull force testing needs and providing reliable assurance for hardware quality inspection.

[0042] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. 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 this utility model also intends to include these modifications and variations.
