Embodiment
Contrast accompanying drawing below, by the description to embodiment, be described in further detail the specific embodiment of the present invention, object helps those skilled in the art to have more complete, accurate and deep understanding to design of the present invention, technical scheme, and contribute to its enforcement.
As depicted in figs. 1 and 2, because existing vibration damper generally adopts sealing encapsulation, flange is formed in the end of outer barrel assembly, by flange by the parts of outer barrel assembly inside as oil sealing, guides and working cylinder assembly compress, guarantee that the pretightning force of vibration damper meets the requirements, ensure the product quality of vibration damper.
As shown in Figure 3, the invention provides a kind of vibration damper pretightning force pick-up unit, comprise the first connection bearing, second and connect bearing, force value sensor and signal processing unit; First connection bearing is connected bearing with second be for inserting in the outer barrel assembly of vibration damper; Force value sensor is for inserting in the outer barrel assembly of vibration damper, and is connected bearing clamping by the first connection bearing with second when detecting; Signal processing unit is connected with force value sensor by signal wire, and the data of detection are passed to signal processing unit by signal wire by force value sensor, show testing result by signal processing unit.
Specifically, as shown in Figure 3, the vibration damper for testing is non-finished product, its working cylinder assembly mainly comprising outer barrel assembly and be arranged at outer barrel assembly inside, and now oil sealing and guides do not load in outer barrel assembly.First connects bearing is connected bearing and matches clamping force value sensor with second, during detection, the first connection bearing is connected bearing with second and loads successively in outer barrel assembly.First connection bearing is connected bearing with second and is circular block shape structure, and connect bearing first and be connected after in bearing loading outer barrel assembly with second, three keeps coaxial state.And, first connects bearing, and be connected the interior diameter size of the overall diameter of bearing and outer barrel assembly with second roughly equal, guarantee that the first connection bearing is connected bearing with second and can be positioned over accurate location fast, improve the accuracy of the stability after installing and testing result.
As shown in Figure 3, force value sensor is pressure transducer, in use, connecting bearing, force value sensor successively by first is connected in bearing loading outer barrel assembly with second, now the first connection bearing is adjacent with working cylinder assembly position, force value sensor is clipped in the first connection bearing and is connected between bearing with second, and second connects bearing and be positioned at the open-ended place of outer barrel assembly.
As shown in Figure 3, vibration damper pretightning force pick-up unit of the present invention also comprises being sheathed on signal wire and inserting second and connects sheath in bearing, and the second center connecting bearing is provided with the through hole allowing sheath insert.Sheath is circular sleeve structure, and signal wire passes from sheath, and sheath has good protective effect to signal wire.
Signal processing unit is force value display and control instrument of the prior art, and it processes for the data detected force value sensor, calculates pretension force value, and has the display screen for showing pretension force value.
Present invention also offers a kind of vibration damper pretightning force detection method, adopt the vibration damper pretightning force pick-up unit of said structure, and comprise following step:
(1) the first connection bearing, force value sensor are connected with second the outer barrel assembly that vibration damper to be tested put into successively by bearing; Be non-finished product for vibration damper to be tested, its working cylinder assembly mainly comprising outer barrel assembly and be arranged at outer barrel assembly inside, now oil sealing and guides do not load in outer barrel assembly;
