Description

Controllable hand-pressing installation mechanism

Technical Field

The utility model belongs to the technical field of the press fit's hand tool is transported in the operation, concretely relates to controllable formula hand installation mechanism.

Background

With the application of the airbag suspension structure to a commercial vehicle, a height control sensor needs to be assembled on a vehicle chassis to adjust the gas pressure inside the airbag, so that the vehicle can run stably. When assembling the height sensor, the bottom matching section 101 of the height valve pin 1 needs to be coaxially assembled and connected with the seat body of the rubber connecting hinge 2 (as shown in fig. 1). The rubber connecting hinge 2 is generally made of a chloroprene rubber elastomer material, the pin 1 is made of free-cutting steel Y12Pb, and when the two parts are assembled, the bottom matching section 101 of the pin 1 needs to penetrate through the pin mounting hole 201 of the elastic rubber body of the rubber connecting hinge 2 by external force. The common practice in the past is: after the matching section 101 at the bottom of the pin 1 is coaxially aligned with the pin mounting hole 201, a hammer is used for knocking the upper end of the pin 1 for mounting. The installation mode has the problems that the force is uncontrollable, and the stress point deviates from the center of the pin installation hole. Moreover, in case too big hard, will cause 1 pins to strike the collision damage of end external screw thread, influence the assembly in 1 top external screw thread later stage of pin and use. Sometimes there is even the possibility that the assembled product will be unusable as it forms a waste product. And the small force can cause the rubber reaction force of the rubber connecting hinge 2, so that the assembly can not be effectively carried out. Moreover, when the hammer is used for knocking the pin 1 for assembly, if a hammering point deviates from the center of the pin mounting hole 201 or the pin 1 is not rightly held by hand, the danger of injuring fingers by a crashing object can also occur.

In contrast, in the prior art, chinese patent publication No. CN209062996U discloses a manual rapid magnetic steel assembling tool. The tool effectively solves the technical problem of how to realize coaxial alignment assembly of a primary-secondary assembly structure. However, when the tool is used, because the stroke of the coaxial assembly cannot be accurately controlled, and the axial fit size of the coaxial assembly is completely determined by artificial feeling operation, the problems of excessive pressing-in or insufficient pressing-in of the coaxial fit of the product are frequently caused, the fit accuracy of the product is affected, and even the possibility of scrapping of the product due to excessive displacement exists. In view of this, the following improvements have been proposed.
