Abstract
The present invention relates to a foldable extending trolley. The present invention is mainly composed of swinging positioning towing pins, moving positioning supporting pins, a front trolley, a rear trolley, overturning table tops and a retractor device, wherein the swinging positioning towing pin is fixed on the front end part of the front trolley; the front trolley and the rear trolley are connected into integration through the retractor device; the moving positioning supporting pins are respectively arranged on the front trolley and the rear trolley; the overturning table tops are respectively arranged at both sides of the front trolley and the rear trolley. The present invention has the advantages that the vertically telescopic motion of the retractor device is utilized to adjust the distance between the front trolley and the rear trolley; the vertically telescopic motion of the retractor device and the horizontal and the vertical motion of the moving positioning supporting pins are combined together to form a supporting network covering six surfaces in upper, lower, front, rear, left and right directions, in this way, the same trolley can be compatible with supporting positions of a plurality of models of cars; the present invention can solve the problem of difficult assembly of partial high positions; the area occupied by the trolley in a return line segment is reduced; the trolley can utilize a ski device to return and achieves an accumulating function of the trolley, and the same linear body can be compatible with the models of cars of different position intervals; besides, the working strength is lightened.
Description
Technical field
What the present invention relates to is a kind of collapsible, multi-functional chassis of stretching, is arranged on the floor mop chain line body.Belong to the conveyer technical field.
Background technology
The structure of existing automotive trim assembly system chassis is simple and crude, function singleness, the chassis volume is big, floor space is big when returning, can not store long-pending putting, can not be on same chassis compatible multiple vehicle, do not satisfy the needs that modern cars is produced, become a technical bottleneck in the automotive trim assembly system.
Summary of the invention
The objective of the invention is to defective, propose a kind of novel chassis, be applied to the automotive trim assembly system,, satisfy the needs that the modern cars variation is produced to solve above-mentioned bottleneck problem at above-mentioned existence.Technical solution of the present invention: its structure by wave positioning towed pin, running fix supporting pin, preceding chassis, back chassis, upset table top, retractor device is formed, wherein wave positioning towed pin be fixed on before the leading section of chassis, preceding chassis is in turn connected into an integral body with the back chassis by retractor device, on chassis and the back chassis, the upset table top was separately positioned on the both sides of preceding chassis and back chassis before the running fix supporting pin was separately positioned on.Advantage of the present invention: the spacing of utilizing the elastic motion of retractor device to regulate forward and backward chassis; With the move left and right of running fix supporting pin with move up and down to combine and formed that covering is upper and lower, the supporting network of comprehensive six faces in front, rear, left and right, like this, just can be on same chassis the Support Position of compatible multiple vehicle; When chassis ran on the technology line segment, the upset table top launched to form a big plane with forward and backward chassis, and the workman of line body both sides may stand on the chassis and assembles with car during assembling, so just can solve the difficult problem of the high station assembling of part; Can utilize the obform guide rail of line end of body to carry out flip-flop movement (unpowered) when chassis returns, thereby table top is shunk, reduce chassis in the floor space of returning on the line segment; Simultaneously, this chassis has all added the rectangular tube structure in the skid device in the both sides of forward and backward chassis, and like this, chassis just can utilize the skid device to return, and has realized the long-pending playing function of chassis, thereby, make the vehicle that same line body can compatible different station spacing; The towing pin that this chassis adopts can wave the location, has alleviated the working strength of manually chassis being pushed to the line body greatly.
Description of drawings
Accompanying drawing 1 is a front view of the present invention;
Accompanying drawing 2 is vertical views of the present invention;
Schematic diagram when accompanying drawing 3 is the online end of body transition of the present invention.
Among the figure 1 waves positioning towed pin, the 2nd, running fix supporting pin, the 3rd, preceding chassis, the 4th, back chassis, the 5th, upset table top, the 6th, retractor device, the 7th, guide roller, the 8th, special-shaped guide rail, the 9th, hydraulic lift.
The specific embodiment
The contrast accompanying drawing, wave positioning towed pin 1 be fixed on before the leading section of chassis 3, preceding chassis 3 is in turn connected into an integral body with back chassis 4 by retractor device 6, running fix supporting pin 2 is separately positioned on preceding chassis 3 and the back chassis 4, the upset table top 5 respectively with preceding chassis 3, the back chassis 4 hinged, the both sides of chassis 3 and back chassis 4 before being arranged on, guide roller 7 is fixed on the upset table top 5.When chassis moved at process section, the wheel of front and back chassis 3,4 supported on the online track body, relied on the engagement of waving positioning towed pin 1 and line body chain to drive chassis and advanced; Upset table top 5 opens fully, regulates the position of retractor device 6 and running fix supporting pin 2 according to the needs that support vehicle, so that workpiece is located fully.Chassis utilizes the guide roller 7 on the upset table top 5 to lead with the engagement of the special-shaped guide rail 8 of line end of body when descending with the hydraulic lift 9 of line body end, thus upset reposefully.When chassis returned, the rectangular tube on the front and back chassis 3,4 was supported on down on the layer line body, and its power is to roll a conveyer or chain-linked conveyer, relied on frictional force to advance, and can realize long-pending playing function by the stopper on the following layer line body.Chassis returns when putting in place, another hydraulic lift 9 of line body head end ejects chassis, under the guiding of the special-shaped guide rail 8 of guide roller 7 online body head ends, ordering about the upset table top opens gradually reposefully, the roller of chassis 3,4 supports again on the online track body before and after after chassis is reached the standard grade, dependence is waved positioning towed pin and is inserted and drive chassis in the conduction chain pin-and-hole and advance, thereby enters process section, circulation and so forth.
