[0025] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] Please see Figures 1-2This utility model provides a pressure testing machine, including a frame 1, on which a carrier module 2, a dotting module 3 and a pressure detection module 4 are provided.

[0027] refer to Figures 2-4 The carrier module 2 includes a first support frame 21, a Y-axis slide rail 22, a first slide plate 23, a fixture 24, and a Y-axis drive mechanism 25. Two Y-axis slide rails 22 are mounted on both sides of the first support frame 21 along the Y-axis direction. The first slide plate 23 is slidably connected to the Y-axis slide rails 22 via sliders on both sides of its bottom, and is driven to slide on the Y-axis slide rails 22 by the Y-axis drive mechanism 25. The fixture 24 is mounted on the first slide plate 23, and the fixture 24 has mounting slots that match the product 5.

[0028] Furthermore, the Y-axis drive mechanism 25 is a cylinder, which is mounted on the first support frame 21 via a fixing plate 251. The output end of the cylinder is provided with a floating joint 252, and the first slide plate 23 is provided with a slot 231 that mates with the floating joint 252. The floating joint 252 is connected to the first slide plate 23 via the slot 231. The fixing plate 251 is also provided with a buffer 253 facing the first slide plate 23. The buffer 253 is used to reduce the impact force on the first slide plate 23 in the Y-axis direction and protect the first slide plate 23 and the cylinder.

[0029] Furthermore, the fixture 24 includes two U-shaped limiting members 241, forming a mounting groove between the two limiting members 241 that matches the product 5. The limiting members 241 are made of hard plastic or metal, possessing sufficient strength and wear resistance for long-term stable use. The dimensions of the mounting groove match the external dimensions of the product 5 to be tested, ensuring accurate positioning of the product 5.

[0030] Furthermore, several pads 232 are spaced apart on the first slide plate 23, with gaps between the pads 232 and the product 5. The pads 232 are made of elastic material, which can cushion and support the product 5, preventing the product 5 from directly contacting the first slide plate 23 and causing damage. The height of the pads 232 is moderate, ensuring that the product 5 is placed stably without affecting the accuracy of the pressure test.

[0031] Furthermore, the marking module 3 is installed on one side of the slide to mark defective products 5. The marking module 3 includes a marking mechanism and a control unit. The marking mechanism can leave obvious marks on the surface of the defective products 5, facilitating subsequent sorting and processing. The marking module 3 is electrically connected to the pressure detection module 4. When the pressure detection module 4 detects that the product 5 is defective, it will trigger the marking module 3 to mark the product 5.

[0032] refer to Figures 5-6The pressure testing module 4 is mounted above the carrier module 2 via a second support frame 41. The pressure testing module 4 includes an X-axis slide rail 42, an X-axis drive mechanism 43, a second slide plate 44, and an upper pressure testing mechanism 45. The X-axis slide rail 42 is mounted on the second support frame 41 along the X-axis direction. The second slide plate 44 is slidably connected to the X-axis slide rail 42 and is driven to slide on the X-axis slide rail 42 by the X-axis drive mechanism 43. The X-axis drive mechanism 43 is a lead screw motor, and the slide table on the lead screw motor is connected to the second slide plate 44. The lead screw motor features high positioning accuracy and smooth movement, ensuring precise movement of the second slide plate 44 in the X-axis direction. The speed and stroke of the lead screw motor can be adjusted by the control system to adapt to the testing requirements of different products 5.

[0033] Furthermore, the upper pressing test mechanism 45 is mounted on the second slide plate 44. The upper pressing test mechanism 45 includes a Z-axis drive mechanism 451, a pressure head 452, and a pressure sensor. The Z-axis drive mechanism 451 is selected as a cylinder or hydraulic cylinder, and the pressure head 452 is connected to the output end of the cylinder or hydraulic cylinder and is driven by the Z-axis drive mechanism 451 to move up and down along the Z-axis. The pressure sensor is connected to the pressure head 452 and is used to detect the pressure value applied by the pressure head 452 to the product 5.

[0034] Furthermore, the pressure head 452 is also equipped with a displacement sensor 453, which is used to detect the displacement of the pressure head 452 in the Z-axis direction. By simultaneously monitoring pressure and displacement data, a pressure-displacement curve of product 5 can be plotted to comprehensively evaluate the pressure characteristics of product 5.

[0035] The frame 1 is equipped with an electrical control box 11, which has operation buttons and a display screen on its front. The control box 11 houses the control system, including a PLC controller, driver, power module, and other electrical components. The operation buttons are used to start and stop the test and switch test modes; the display screen shows real-time test data, test results, and equipment status information. The frame 1 also features an inclined slide 12, the upper end of which connects to the carrier module 2 to receive qualified products 5, and the lower end of the slide 12 collects the qualified products 5.

[0036] The working process of this pressure testing machine is as follows: First, the product to be tested 5 is placed in the mounting slot of the fixture 24 to ensure that the product 5 is stably positioned. Then, the test program is started by operating the button. The Y-axis drive mechanism 25 drives the first slide plate 23 to move, sending the product 5 to the test position. The X-axis drive mechanism 43 drives the second slide plate 44 to move, so that the upper pressure testing mechanism 45 is aligned with the test point of the product 5. The Z-axis drive mechanism 451 drives the pressure head 452 to move downward, applying pressure to the product 5. The pressure sensor and displacement sensor 453 collect pressure and displacement data in real time and transmit them to the control system for analysis. The control system judges whether the product 5 is qualified according to the preset standard. If it is not qualified, the marking module 3 is triggered to mark the product 5. After the test is completed, the Z-axis drive mechanism 451 drives the pressure head 452 to rise, and the Y-axis drive mechanism 25 drives the first slide plate 23 to return to the initial position, completing one test cycle.

[0037] In summary, this pressure testing machine has a compact structure and is easy to operate, enabling efficient and accurate product pressure testing, thus improving testing efficiency and accuracy. Through modular design, each functional module can be adjusted and optimized according to actual needs, adapting to the testing requirements of different products. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial application value.
