A kind of floating disc that can automatic capturing

Technical field

The utility model belongs to auto production line corollary equipment technical field, and especially a kind of floating disc that can automatic capturing is mainly used in chassis the aiming at of part while attaching together with vehicle body.

Background technology

Automobile assembling process relates to the amalgamation of chassis part and vehicle body, and this process generally attaches together station and carries out on chassis. Automobile chassis tray is mainly used for assembly shop engine and attaches together on line, after the parts such as cradle assembly, engine mission assembly, front overhang, rear overhang, fuel tank, blast pipe are located on tray and vehicle body carry out entirety and attach together. Amalgamation front chassis part disperses to be placed on and to attach together on pallet, and the assembling that specific station is realized chassis part on ground is shaped, and vehicle body is generally hung aloft by supporting mechanism. Combine with vehicle body thereby chassis part is lifted to when amalgamation in the air, this process need chassis part is realized and being aimed at vehicle body. But before attaching together, the vehicle chassis component and the skyborne vehicle body that attach together on ground on pallet often can not reach accurate alignment, thereby chassis part energy rapid alignment vehicle body attaches together smoothly when conveniently attaching together, need pallet can realize floating of direction all around, thereby under any circumstance can realize the amalgamation of chassis part and vehicle body.

But current relocatable tray can not automatically recover initial centre position under non-amalgamation state, is unfavorable for the placement of part, if manually recovered, precision is poor, and effect is undesirable, therefore, need to provide a kind of and can recover the floating disc in centre position by automatic capturing.

Utility model content

The purpose of this utility model is to provide a kind of floating disc that can automatic capturing, under non-amalgamation state, by position-limit mechanism and extension spring are set, the platen that departs from centre position is automatically reset, and without operating personnel's hand-reset, has higher precision.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of floating disc that can automatic capturing, comprise base plate and platen, base plate is provided with multi-directional ball bearing, platen is supported on multi-directional ball bearing, be symmetricly set on the both sides of floating disc for the extension spring of automatic capturing, the two ends of extension spring are separately fixed at the edge of platen and base plate, on platen, offer spacing hole, platen and base plate are linked together through spacing hole for the stopping means that limits platen domain of walker, and there is flying height between stopping means and spacing hole hole wall.

Preferably, be provided with the spring pull bar parallel with table top at platen edge, spring pull bar is provided with fixing hole, on base plate edge, be provided with the spring dead plate perpendicular to base plate, and spring fixed column is set on spring dead plate, spring fixed column center is provided with screwed hole, and is provided with the fastening bolt coordinating with screwed hole.

Preferably, described platen bottom surface is embedded wearing plate with the position that multi-directional ball bearing contacts.

Preferably, described multi-directional ball bearing arranges four, and described stopping means is diagonal and arranges two.

Preferably, described stopping means is made up of caging bolt, nut and sleeve pipe, sleeve pipe upper end is provided with spacing ring, and the diameter of spacing ring is greater than spacing hole diameter, and the base plate below spacing hole is provided with counterbore, sleeve pipe is through after spacing hole, insert in counterbore lower end, and described caging bolt inserts in sleeve pipe and from counterbore passes, and nut is spun on bolt, by adjusting nut, realize locking and the release of platen.

Compared with prior art, the utlity model has following beneficial effect:

First, platen in the utility model floats and departs from behind centre position towards any direction, set extension spring is elongated, under non-amalgamation state, platen is pulled back to centre position and realizes automatic capturing under the elastic force effect of extension spring, thereby is convenient to the placement of part, therefore, this device can be realized the automatic capturing of platen without manual intervention in the situation that, can save the operating time, improves operating efficiency.

Second, in the utility model, the spacing hole of platen and stopping means match the domain of walker of platen are limited, in the time that platen passes through multi-directional ball bearing floating, it floats and is limited in the scope of spacing hole size, therefore, can prevent that platen floating range is excessive and deviate from from base plate, and, in the time floating to aligned position, by screwing nut, make the spacing ring of sleeve pipe be pressed on platen and then locking platen, prevent from attaching together the unsteady skew of platen in process.

The 3rd, the position that platen of the present utility model and multi-directional ball bearing contact is embedded wearing plate, can reduce the wearing and tearing between platen and multi-directional ball bearing, and can change wearing plate according to abrasion condition.

The 4th, spacing hole and stopping means are diagonal setting, can improve the unsteady stability of platen.
