Description

Technical Field

[0001] The utility model relates to the field of automobile component testing fixtures, in particular to an adjustable and multi-adaptable sensor fixture. Background Art

[0002] Rod displacement sensors play a vital role in the testing of automotive parts. They are mainly used to accurately measure and record the displacement and deformation of parts under different loading conditions. The clamping method of rod displacement sensors is mainly to fix the sensor through a special fixture or mounting bracket. Usually, the fixture is designed with fixed sizes to adapt to sensors of different models and sizes to ensure the stability of the clamping. The fixture can be fixed with bolts and nuts to ensure that the sensor is stable and motionless during the test. Some fixtures may use magnetic bases or vacuum adsorption methods for quick and flexible installation on metal or smooth surfaces. In order to prevent the sensor from loosening or slipping during the test, the fixture is usually made of high-strength materials and designed with anti-skid pads or rubber pads. For certain specific sizes, customized fixtures may also be required to ensure that the sensor can be accurately positioned and fixed in the key position of the test piece.

[0003] However, in actual use, due to the large number of sensor manufacturers, models and categories, it is necessary to design and process a variety of compatible fixtures, which makes daily testing work extremely inconvenient. The limitation of the individual adaptation of the fixture tooling also means that once the sensor is damaged, its compatible fixture can only be idle and scrapped, which causes a huge waste of manpower and material resources. On the other hand, since different test objects and environments have different size and model requirements, if the fixture is designed to be a fixed size or model, it will limit its scope of application and cannot adapt to various different test needs. This means that when facing different test conditions, the fixture needs to be replaced frequently, which increases the complexity and cost of the work. In addition, fixed-size fixtures may not be convenient enough during adjustment and installation, resulting in reduced test efficiency. In some test conditions, lowering the adaptation standard and using an unsuitable fixed-size fixture may not provide sufficient stability and accuracy, which in turn affects the reliability of the test results. Utility Model Content

[0004] The utility model aims to provide an adjustable multi-adaptable sensor fixture to solve the technical problem that the existing fixture can only be applicable to one type of sensor.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An adjustable and multi-adaptable sensor clamp comprises a clamping mechanism, a guiding mechanism and a locking mechanism. The clamping mechanism comprises a clamping frame and a rubber bushing. The guiding mechanism comprises a guiding rod. The locking mechanism comprises a sliding guide rail frame and a locking screw. Limiting portions are provided at both ends of the guiding rod. The main body of the clamping frame is in the shape of [. There are connecting ears on both sides of the main body. The connecting ears are provided with through holes, and the guide rod passes through the through holes. There are two clamping frames, which are symmetrically slidably mounted on the guide rod. The rubber bushing is symmetrically and detachably mounted on the inner side of the main body of the clamping frame. Slide grooves are provided at both ends of the sliding guide rail frame. The locking screw passes through the slide groove and is detachably connected to the clamping frame.

[0007] The principle of this scheme is:

[0008] In actual application, loosen the locking screw on one side, and then pull the clamping frame on the same side along the guide rod to the appropriate position, so that a gap sufficient to clamp the sensor is generated between the two clamping frames, pass the sensor perpendicular to the fixture through the aforementioned gap, adjust the sensor to the appropriate position of the rubber bushing, pull the aforementioned pulled clamping frame back along the guide rod, clamp the sensor, and finally lock the aforementioned loosened locking screw to complete the clamping installation of the sensor.

[0009] The advantages of this solution are:

[0010] 1. This solution can adjust the clamping space size of the clamping frame according to the size and shape of the sensor to be clamped, and can clamp multiple types and models of sensors, avoiding the technical problem that one clamp can only be used for one sensor. It can effectively save manpower and material resources, and at the same time effectively broaden the scope of application of the clamp and the applicable environment, and has high flexibility and universality.

[0011] 2. This solution has a simple structure, is easy to use, and is very convenient to replace and adjust sensors, which greatly saves the time and economic costs of users.

[0012] 3. The rubber bushing in this solution is designed to be detachable. The user can replace the appropriate rubber bushing according to the type and size of the clamped sensor. If the clamped sensor surface is arc-shaped, a bushing with an arc-shaped groove can be used. If the clamped sensor surface is flat, a rubber bushing with a flat end face can be used.

[0013] Preferably, as an improvement, the guide mechanism further includes a reset spring, which is sleeved on the guide rod and abuts against the connection ear of the clamping frame and the limiting portion of the guide rod. When the clamping mechanism is opened, the clamping frame on the side in contact with the reset spring compresses the reset spring, and the clamping frame on the reset spring side is released after the sensor is placed in a suitable position. The inertia of the reset spring pushes the clamping frame, so that the clamping mechanism clamps the sensor, and the restoring force of the spring also provides a certain clamping effect to ensure that the sensor is firmly clamped.

[0014] Preferably, as an improvement, the guide mechanism further includes a guide handle, the guide handle includes a threaded connecting rod and a handle, one end of the threaded connecting rod is fixedly connected to the clamping frame, and the other end is fixedly connected to the handle. By pulling and pushing the guide handle, the opening and closing of the clamping mechanism can be controlled more simply and conveniently, and the threaded connecting rod can provide a certain guiding effect to prevent the clamping mechanism from tilting during operation.

[0015] Preferably, as an improvement, one end of the guide rod is provided with a thread, and the limiting part of the threaded end is a nut. The connection between the nut and the threaded end of the guide rod can facilitate the disassembly and assembly of the entire structure, and can be stored and carried, with high flexibility and preventive applicability.

[0016] Preferably, as an improvement, the guide mechanism further comprises a guide rod connection fixing plate, the guide rod connection fixing plate is connected to the non-threaded end of the guide rod, and the guide handle passes through the guide rod connection fixing plate. The guide rod connection fixing plate is used to connect and fix the guide rods to keep the guide rods relatively parallel, and at the same time cooperates with the threaded connecting rod of the guide handle to provide a certain guiding effect.

[0017] Preferably, as an improvement, it further comprises a connector, one end of which is fixedly connected to the sliding guide rail frame, and the other end of which is provided with a thread. The threaded end of the connector is used to connect to a magnetic bracket or a rod bracket to complete the fixation.

[0018] Preferably, as an improvement, the cross-section of the rubber bushing relative to the end face is rectangular. The rubber bushing with a rectangular cross-section is used to clamp and fix a sensor with a planar shape.

[0019] Preferably, as an improvement, the opposite end faces of the rubber bushing are further provided with arc-shaped notches. The rubber bushing with the arc-shaped notch is used to clamp and fix a sensor with a cylindrical shape.

[0020] Preferably, as an improvement, the opposite end surface of the rubber bushing is also provided with anti-skid patterns, which are transverse patterns and are perpendicular to the direction of the clamped sensor. BRIEF DESCRIPTION OF THE DRAWINGS
