Abstract

The utility model discloses a vibration sensor fixing seat which comprises a seat body, a stud and a magnet, wherein an internal thread through hole and an installation groove are formed in the seat body, the internal thread through hole is in threaded connection with the stud, the stud is used for connecting a vibration sensor, the magnet is arranged in the installation groove in an absorbing mode, and the top surface of the magnet is flush with the top surface of the seat body. The engine body has the advantages that through the arrangement of the magnet, the vibration sensor can be detached from the engine body only by taking down the base body by hands, the glue bonding operation is replaced, the vibration sensor does not need to be scraped by a blade in the detaching process, and the damage of the vibration sensor is prevented.

Description

Vibration sensor fixing base

Technical Field

The utility model relates to the technical field of engine testing, in particular to a vibration sensor fixing seat.

Background

During the running process of the vehicle, the axle plays the roles of transmitting power and bearing load, and a main speed reducer and a differential in the axle can generate vibration and noise due to gear processing, assembly, abrasion and the like during the working process, so that the main speed reducer and the differential greatly contribute to the acceleration noise outside the vehicle and the noise inside the vehicle. Along with the improvement of the requirements of people on living quality, the requirements of people on noise, vibration and harshness (NVH) of the whole vehicle are higher and higher, the requirements on the NVH of the engine are higher and higher, and the vibration noise test of the engine becomes necessary work. At present, vibration noise testing is carried out on an engine by adopting a vibration sensor for testing, but the vibration sensor is directly adhered to the engine by glue during the testing of the existing vibration sensor, a blade is required to be used for scraping the vibration sensor during the disassembly process, and the sensor is easy to damage.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is how to prevent the damage of the vibration sensor.

In order to solve the technical problems, the utility model provides the following technical scheme:

the utility model provides a vibration sensor fixing base, includes pedestal, double-screw bolt and magnet, internal thread through-hole and mounting groove have been seted up on the pedestal, internal thread through-hole threaded connection the double-screw bolt, the double-screw bolt is used for connecting vibration sensor, the mounting groove internal suction is equipped with magnet, the magnet top surface flushes with the pedestal top surface.

Through the setting of magnet, only need bare-handed take off the pedestal alright dismantle vibration sensor from the engine organism, replaced glue bonding operation, the dismantlement process need not scrape down vibration sensor with the blade, has prevented vibration sensor's damage.

Preferably, the mounting groove is arranged close to the side edge of the base body.

Preferably, the seat body is cylindrical.

Preferably, the stud is a socket head stud.

Preferably, a drawing part is further fixed at one end of the seat body far away from the magnet.

Compared with the prior art, the utility model has the beneficial effects that:

through the setting of magnet, only need bare-handed the pedestal of taking off alright dismantle vibration sensor from the engine organism, replaced the glue bonding operation, the dismantlement process need not scrape down vibration sensor with the blade, has prevented vibration sensor's damage.

Detailed Description

In order to facilitate the understanding of the technical solutions of the present invention for those skilled in the art, the technical solutions of the present invention will be further described with reference to the drawings attached to the specification.

In this application, unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and encompass, for example, both fixed and removable connections or integral parts thereof; the connection can be mechanical connection, electrical connection or communication; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

In this application, unless explicitly stated or limited otherwise, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1 to 3, the embodiment discloses a vibration sensor fixing seat, which includes a seat body 1, a stud 2 and a magnet 3, in the embodiment, the seat body 1 is cylindrical, the seat body 1 is provided with an internal thread through hole 11 and a mounting groove 12, the internal thread through hole 11 is in threaded connection with the stud 2, the stud 2 is used for being in threaded connection with a vibration sensor 5, the magnet 3 is sucked in the mounting groove 12, and the top surface of the magnet 3 is flush with the top surface of the seat body 1, so that the seat body 1 can be stably fixed on an engine body 6.

Through the setting of magnet 3, only need bare-handed the pedestal 1 alright dismantle vibration sensor 5 from engine organism 6, replaced the glue bonding operation, the dismantlement process need not scrape down vibration sensor 5 with the blade, has prevented vibration sensor 5's damage.

Furthermore, the mounting groove 12 is disposed near the side of the seat body 1, so as to facilitate the adsorption of the magnet 3 and the seat body 1.

Further, the stud 2 is a hexagon socket head stud.

Still further, the one end that the pedestal 1 kept away from magnet 3 still is fixed with draws portion 4, makes things convenient for the dismouting of pedestal 1.

The working principle of the utility model is as follows: the vibration sensor 5 is connected with the base body 1 through the stud 2, and the base body 1 is adsorbed on the engine body 6 through the magnet 3, so that the vibration sensor 5 is installed; due to the arrangement of the magnet 3, the vibration sensor 5 can be detached from the engine body 6 only by taking down the base body 1 by hands, the glue bonding operation is replaced, the vibration sensor 5 does not need to be scraped by a blade in the detaching process, and the damage of the vibration sensor 5 is prevented.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
