Description

Technical Field

[0001] This utility model relates to the field of load force testing technology, and in particular to a waveform gasket load force testing fixture. Background Technology

[0002] In precision machinery, automotive electronics, aerospace, and home appliances, corrugated gaskets are widely used as important elastic elements in applications such as bearing preload, clearance elimination, anti-loosening, and vibration damping. Their core performance parameter—effective load (i.e., the force value that can be provided under a specified compression)—directly affects the performance, reliability, and lifespan of the entire assembly.

[0003] like Figure 4 The waveform gasket shown is tested by manually controlling the compression amount with a regular micrometer and taking the reading with a simple force gauge. Due to the lack of a precise displacement reference and an independent displacement measurement system, the control error of the compression amount is large, resulting in unreliable force measurement results. In addition, the displacement and force values ​​need to be manually controlled and read separately during the test, which is complicated, highly dependent on the operator's technical level, and has low testing efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a test fixture for the load force of waveform gaskets, which can improve the accuracy and efficiency of quality control of waveform gasket products.

[0005] The technical solution of this utility model is as follows: This utility model discloses a waveform gasket load force testing fixture, including a base; A placement seat is provided on the base, and a placement groove is provided on the top of the placement seat. The placement groove is adapted to the corrugated gasket and is used to limit the corrugated gasket. The push-pull force measuring mechanism includes a lifting assembly and a push-pull force gauge connected to the output end of the lifting assembly. The lifting assembly is mounted on the base. The bottom of the push-pull force gauge is connected to a push-pull force head. The push-pull force head is mounted above the placement seat and corresponds to the placement groove, and is used to measure the push-pull force of the wave-shaped pad. A height measuring assembly includes a mounting bracket and a digital altimeter mounted on the mounting bracket. The digital altimeter is mounted on the side of a push-pull force gauge via the mounting bracket and is electrically connected to the push-pull force gauge for measuring the displacement of the push-pull force gauge relative to the surface of the base.

[0006] As can be seen from the above scheme, the placement seat is used to place the wave-shaped gasket, thereby limiting the position of the wave-shaped gasket. The lifting component is used to drive the push-pull force head down to the placement groove position, so that it contacts the wave-shaped gasket to measure the push-pull force. The height measuring component is used to accurately measure the displacement of the push-pull force gauge relative to the surface of the base, and the load force is accurately measured in combination with the push-pull force gauge.

[0007] The push-pull force head includes a mounting part and a pressure head. The push-pull force head is connected to a connecting rod at the bottom of the push-pull force gauge. The outer wall of the end of the connecting rod is threaded, and the mounting part is provided with a threaded hole adapted to the connecting rod. The push-pull force head is threadedly engaged with the connecting rod through the threaded hole. Therefore, the push-pull force head can be detachably installed on the connecting rod through the mounting part, facilitating the measurement of load force on wave pads of different sizes by combining it with different mounting bases.

[0008] The lifting assembly includes a mounting base, a threaded rod disposed within the mounting base, a nut fixing seat threadedly engaged with the threaded rod, a transmission wheel set, and a hand crank. The push-pull force gauge is fixedly connected to the nut fixing seat via a mounting plate. The transmission wheel set includes a first bevel gear and a second bevel gear meshing with the first bevel gear. The threaded rod is coaxially connected to the first bevel gear, and the hand crank is fixedly connected to the second bevel gear. Therefore, the threaded connection between the nut fixing seat and the threaded rod converts the rotational motion of the threaded rod into the up-and-down movement of the push-pull force gauge. The hand crank, by rotating, drives the first and second bevel gears to mesh, thereby rotating the threaded rod. The hand crank is positioned on the side for easy manual operation by the operator to raise and lower the push-pull force gauge.

[0009] The mounting base is vertically provided with a guide groove, and the mounting plate extends out of the guide groove and connects to the push-pull force gauge.

[0010] The base is provided with a sliding groove, on which a carrier plate slidably engages. The carrier plate is provided with a limiting groove that matches the placement seat. Therefore, the carrier plate, through its sliding engagement with the sliding groove on the base, facilitates the pushing and pushing of the placement seat under the corresponding push-pull pressure head, enabling precise alignment.

[0011] The push-pull force gauge has a control panel on its front side, which includes control buttons and a display screen. The display screen is used to show the force value.

[0012] The digital altimeter includes a digital height scale and an electronic digital display mounted on the height scale. Therefore, the electronic digital display is used to display the height value of the movement. Attached Figure Description

The digital height gauge 7 is mounted to the side of the push-pull force gauge 4 via the mounting bracket 6 and is electrically connected to the push-pull force gauge 4. The digital height gauge 7 includes a digital height scale 71 and an electronic digital display 72 mounted on the digital height scale 71 for measuring the displacement of the push-pull force gauge 4 relative to the surface of the base 1. The digital height scale 71 has height graduations along the vertical direction. Figure 4 as well as Figure 5 As shown, the waveform pad is a waveform-shaped annular pad, and its reference numeral is 100.

[0016] The push-pull pressure head 5 includes a mounting part 51 and a pressure head 52.

A guide groove 311 is vertically provided on the mounting base 31, and the mounting plate extends out of the guide groove 311 and connects to the push-pull force gauge 4. In this embodiment, when the hand crank 34 rotates, it drives the second bevel gear 352 to rotate, and the second bevel gear 352 drives the first bevel gear 351 to mesh and transmit power, thereby transmitting power to the threaded rod 32. The nut fixing seat 33 drives the push-pull force gauge head 5 to move up and down.

[0018] The base 1 is provided with a sliding groove 11, and a carrier plate 8 is slidably fitted on the sliding groove 11. The carrier plate 8 is provided with a limiting groove 81 that is adapted to the placement seat 2. In this embodiment, the limiting groove 81 is parallel to the Y-axis.

[0019] The working process of this utility model is as follows: by rotating the hand crank 34, the push-pull force gauge head 5 is moved downward until the display screen of the push-pull force gauge 4 shows a small value and then stops; the position of the digital height gauge 7 is reset to zero, then the push-pull force gauge head 5 is moved upward, and then the push-pull force gauge value is reset to zero; the wave plate 100 is placed into the placement groove 21 of the placement seat 2; the push-pull force gauge head 5 is moved downward until the digital height gauge 7 displays a value of 1mm, then the push-pull force gauge head 5 stops moving, and the value displayed by the push-pull force gauge is read, which is the effective load of the wave plate 100.
