Description

Gear shifting handle detection nondestructive dismounting structure

Technical Field

The utility model relates to a handle reliability detection area shifts, very much relates to a handle of shifting detects with harmless dismantlement structure.

Background

In recent years, with the gradual improvement of living standard of people, the popularization rate of automobiles is higher and higher, and the reliability of the use of the gear shift handle as a key component of driving operation is important. The shift handle usually includes the gear level and the shift handle that the driver of being convenient for gripped, shift handle and gear level mainly are connected with the buckle, as in fig. 1, shift handle lower extreme has the hole that is used for the cartridge on the gear level, in order to avoid the cartridge to shift handle pine on the gear level to take off, still install the jump ring 11 that bends into the U-shaped in the hole of shift handle, shift handle's radial ascending bilateral symmetry is provided with the draw-in groove 20 that supplies jump ring 11 card to go into, when the gear level inserts the hole, to both sides strut jump ring 11, until draw-in groove 20 reachs jump ring 11 position, jump ring 11 card goes into in draw-in groove 20, thereby restrict the gear level in the axial, avoid gear level and shift handle pine to take off.

During actual production, because the difference between the processing technologies of the gear shifting lever and the gear shifting handle is large, a host factory usually entrusts different manufacturers to produce; when pulling out the power test to shifting handle, can't directly detect the handle of shifting and the gear level of assembling in pairs, but need install the handle of shifting and detect independently on examining test table, then pull down the packing again. Therefore, the existing detection method is to insert the gear shifting handle to be tested on a pull rod with a structure consistent with that of the gear shifting rod, pull the gear shifting handle to be tested off the pull rod, and detect whether the pulling-off force meets the requirement, but the detection method forcibly pulls the gear shifting handle off the pull rod, after long-time detection, the clamping groove on the pull rod is easily abraded, and the subsequent detection accuracy is affected, so that how to pull down the gear shifting handle after detection under the condition of not abrading the pull rod becomes the problem to be solved urgently.

Disclosure of Invention

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide a structural design ingenious, the handle of shifting dismantles easily, and is little to pull rod wearing and tearing, is favorable to improving life and detects the harmless structure of dismantling of handle of shifting of accuracy.

In order to solve the technical problem, the utility model discloses a following technical scheme:

a nondestructive dismounting structure for detecting a gear shifting handle is characterized by comprising a bottom plate and a pull rod vertically connected to the bottom plate, wherein clamping grooves corresponding to clamping springs in the gear shifting handle to be tested are symmetrically formed in an outer circular surface of the upper end of the pull rod, and the size of each clamping groove is completely consistent with that of a clamping groove in the gear shifting rod matched with the gear shifting handle to be tested, so that when the gear shifting handle to be tested is inserted into the upper end of the pull rod, the clamping springs in the gear shifting handle to be tested can be clamped into the clamping grooves of the pull rod; the pull rod is provided with a pull groove which is arranged in a penetrating manner along the radial direction, the pull groove extends from bottom to top and is intersected with the clamping groove, and the penetrating direction of the pull groove on the pull rod is vertical to the penetrating direction of the clamping groove on the pull rod; a top supporting plate capable of moving vertically is installed in the pull groove, and the width of the top supporting plate is consistent with the diameter of the pull rod; the bottom plate is also vertically provided with a liftable jacking mechanism, the jacking mechanism is connected with the jacking plate, and the jacking plate can ascend to the position of the clamping groove under the action of the jacking mechanism.

Adopt above-mentioned structure, because the width of propping up the fagging is unanimous with the diameter of pull rod, the direction mutually perpendicular that link up of kerve and draw-in groove moreover, in case the fagging rises to draw-in groove position, the middle part of draw-in groove will be clogged to the fagging. Particularly, be exactly after fixed pulling-off force detects, will push up the fagging through shoring mechanism and upwards push up, fill in the jump ring middle part, fill the middle part position of draw-in groove, push away the jump ring and deviate from the draw-in groove, then just can take off from the pull rod with light handle of just shifting.

Like this, through two cylinders synchronous lifting that the symmetry set up, can realize the reciprocating of top fagging.

Furthermore, a sleeve is slidably sleeved on the pull rod, and the inner diameter of the sleeve is consistent with the outer diameter of the pull rod; the sleeve is connected with the ejector rod.

Because the pull groove almost cuts the pull rod into two halves, and the synchronous lift in-process of cylinder, in case one of them cylinder jamming causes desynchronously, the guide post of fagging can take place to twist reverse in the hole of pull rod to probably strut the pull rod of pull groove both sides, make the pull rod warp. The sleeve sleeved on the pull rod is arranged on the ejector rod, so that the pull rod can be effectively prevented from being expanded and deformed, and the service life of the whole body is prolonged.

Furthermore, wing plates formed by extending towards two sides along the direction of the ejector rod are arranged on the sleeve, and the wing plates are connected with the ejector rod.
