Description

Technical Field

[0001] The utility model belongs to the technical field of leaf spring inspection, and in particular relates to a leaf spring simulated vehicle loading inspection device. Background Art

[0002] Leaf springs, as elastic elements widely used in automobile suspensions, are composed of multiple alloy spring leaves, which are of approximately equal strength and excellent elasticity. They have a simple structure, reliable operation, low cost, and convenient maintenance. However, the arc height manufacturing accuracy of leaf springs is crucial to the user experience, so arc height detection becomes a necessary link. Although the utility model patent with announcement number CN214621688U provides a leaf spring simulated loading inspection device, this device has significant shortcomings. When adjusting the spacing between the detection sliders, it is necessary to slide manually and rely on bolts to fix. The process is cumbersome and it is difficult to adjust the two sliders synchronously. In addition, as an independent tool, the detection pin needs to be manually inserted into the leaf spring ear, which is prone to errors, easy to move, and easy to lose, greatly affecting the detection efficiency and accuracy.

[0003] Therefore, it is very necessary to invent a leaf spring simulation loading inspection device. Utility Model Content

The test slide is provided with the test slot, the test pin is slidably mounted in the test slot, the two limit slides are fixedly mounted on the test pin, and the positioning mark is fixedly mounted on one end face of the test pin.

The ball nuts are respectively installed on the two sections of spirals with different rotation directions, and the two ball nuts move in opposite directions.

[0008] Preferably, the limit plate is located in the middle of two sections of the linear screw with different rotation directions, the two ball nuts are located on both sides of the limit plate, and the limit plate is located below the two test slides.

[0009] Preferably, the test slide is an "L"-shaped structure, a test slot is provided on one side of the test slide, the test slot is an annular slot, and the test slot allows the test pin to slide.

[0020] As attached Figure 1 To Attachment Figure 3 As shown:

[0021] The utility model provides a leaf spring simulated loading inspection device, comprising a linear adjustment seat 1, a test slider 2, a knob 3 and a positioning mark 4. The test slider 2 is installed on the linear adjustment seat 1, and the knob 3 is fixedly installed thereon; the positioning mark 4 is fixedly installed on both the linear adjustment seat 1 and the test slider 2. The positioning mark 4 is arranged so that an operator can intuitively understand the position of the test slider 2, which is convenient for accurate adjustment and detection.

[0022] The linear adjustment seat 1 includes a base 11, a slide 12, a linear screw 13, a limit plate 14 and a ball nut 15; the positioning mark 4 is fixedly installed on the outer surface of the base 11, the slide 12 is opened through the middle of the base 11, and the linear screw 13 is rotatably installed in the slide 12. Either end of the linear screw 13 rotates through the base 11 and is fixedly connected to the external knob 3. The linear screw 13 is rotatably connected to the limit plate 14, and the limit plate 14 is fixedly installed in the slide 12; two ball nuts 15 are mirror-symmetrically installed on the linear screw 13, and the ball nuts 15 are fixedly connected to the test slider 2, and the test slider 2 is slidably installed in the slide 12. The linear adjustment seat 1 adopts a bidirectional thread adjustment structure. By simply rotating the knob 3, the synchronous movement of the two test sliders 2 can be achieved, which not only greatly improves the accuracy and efficiency of the adjustment, but also significantly simplifies the operation steps.

[0023] The test slide 2 includes a test slide 21, a test slot 22, a test shaft 23 and a limit slide 24. The test slide 21 is fixedly mounted on the ball nut 15 and slidably mounted in the slide 12. The test slide 21 is provided with the test slot 22, the test shaft 23 is slidably mounted on the test slot 22, the two limit slides 24 are fixedly mounted on the test shaft 23, and the positioning mark 4 is fixedly mounted on one end face of the test shaft 23. The test slide 2 has an ingenious structural design, which effectively optimizes the inspection process of the leaf spring and significantly reduces the operation time.

[0024] Embodiment 1:

[0025] Specifically, the base 11 is a rectangular structure, and the linear screw 13 rotatably installed in the slide slot 12 opened in the base 11 is a bidirectional thread, having two sections of threads with different rotation directions, that is, one section is a left spiral and the other section is a right spiral. The two sections of spirals with different rotation directions are respectively installed with the ball nuts 15, and the two ball nuts 15 move in opposite directions. By rotating the knob 3, the bidirectional thread of the linear screw 13 can be driven to move, thereby driving the two ball nuts 15 to move in opposite directions. This synchronous and opposite movement mode allows the two test sliders 2 to approach or move away at the same time, providing a precise adjustment range for the detection of leaf springs.

[0026] Specifically, the limit plate 14 is located in the middle of two sections of the linear screw 13 with different rotation directions, the two ball nuts 15 are located on both sides of the limit plate 14 , and the limit plate 14 is located below the two test slides 21 .

[0027] Specifically, the test slide 21 is an "L"-shaped structure, which facilitates the quick and accurate insertion of the coil ear of the leaf spring onto the test shaft 23, without the need to insert the test shaft 23 individually into the coil ear of the leaf spring. The test slot 22 is opened on one side of the test slide 21, and the test slot 22 is an annular groove. The test slot 22 allows the test shaft 23 to slide.

[0028] Specifically, the coiled ear of the leaf spring allows the test shaft 23 to be inserted, and two limit sliding discs 24 are fixedly installed at one end of the test shaft 23. The two limit sliding discs 24 are located on both sides of the test slot 22. The test shaft 23 and the limit sliding disc 24 are installed together to form a "stem"-shaped structure. This design can limit the movement of the test shaft 23 through the limit sliding disc 24 to avoid the loss of the test shaft 23, and only allows the test shaft 23 to move up and down, thereby avoiding the test shaft 23 from being offset or misaligned.

[0029] Embodiment 2:

[0030] First, the operator drives the linear screw 13 to rotate by rotating the knob 3 according to the specifications and dimensions of the leaf spring to be tested. The linear screw 13 adopts a bidirectional thread design. When it rotates, the two ball nuts 15 move in opposite directions along the spiral parts of the linear screw 13 with different rotation directions. This design enables the two test slides 2 to move closer or farther away synchronously.

[0031] During the movement of the test slide block 2 , the test slide seat 21 slides along the slide groove 12 to ensure the smooth movement of the test slide block 2 to adapt to the steel leaf spring ears of different sizes.

[0032] When the test slide block 2 moves to the appropriate position, the operator inserts the ear of the leaf spring into the test shaft 23. Since the test shaft 23 and the limit slide plate 24 are in a "stem" shape, the limit slide plate 24 can limit the range of motion of the test shaft 23 to prevent it from being lost or offset. This design not only facilitates the operator's work, but also improves the accuracy and reliability of the detection.

[0033] During the testing process, the operator can understand the current position of the test slide 2 and the test shaft 23 by observing the positioning mark 4, so as to make precise adjustments and tests. The setting of the positioning mark 4 enables the operator to intuitively understand the state of the device, thereby improving work efficiency.

[0034] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
