Abstract
The utility model relates to a dismantling-and-assembling machine for saloon car independent suspension devices, which comprises two pairs of spring hook arms. A supporting guide-bar is provided with a rack and a transmission box engaged with the rack to achieve transmission, a pair of upper spring hook-spring is hinged on the transmission box body, a worm-wheel worm transmission pair driven by a handwheel is arranged in the transmission box, the worm-wheel worm transmission pair can drive a gear engaged with a guide rack; each pair of spring hook arm is a groove-shaped hook arm having the arc matching with the convaluting arc of the spring, the groove shapes of the upper and the lower spring hook arms are arranged oppositely. The technical proposal fully makes use of the deceleration rotation, labor-saving run, and self-locking performance of the worm-wheel worm transmission pair, and the spring hook arms are stabilized and fastened by a multi-point damping spring so that the dismantling-and-assembling operation of the independent suspension device is not limited to be coaxial with a shock absorber, the applied field of the dismantling-and-assembling machine having the technical proposal is expanded, and the dismantling-and-assembling machine has reliable security.
Description
Technical field
The utility model relates to the tooling device of implementing the partition of car independent suspension device, assembly operation.
Background technology
Dismounting car independent suspension device need use professional frock changer equipment.The agent structure of its changer is: the bottom is provided with damper body jig, and top is provided with the spring stay hook.Existing changer is on the basis of fixing damper, drives the spring stay hook that moves axially top by leading screw, compresses or loosens its damping spring and realize dismounting or assembly operation.Leading screw drives, drives the spring stay hook by handwheel and its driving cog and moves up and down.The technical problem underlying that prior art exists is: the spring stay hook is for to be provided with fixed hook by spring two symmetrical sides, and 2 hooking structures make spring stress very inhomogeneous, to the poor stability of spring, potential safety hazard are arranged in its operation task; In addition, its underpart is the jig structure that is installed in the damper body, this structure only is applicable to the independent suspension device of damper and the coaxial setting of damping spring, and for the non-coaxial configuration independent suspension device as brand cars such as Audi, red flags, existing changer just can't use at all.
The utility model content
Goal of the invention of the present utility model is to provide a kind of car independent suspension device changer of the enforcement dismounting operation task that not limited by the coaxial or non-coaxial configuration of independent suspension device, can be reliable, safe.The car independent suspension device changer technical scheme that the utility model provides, its major technique content is: a kind of car independent suspension device changer, this changer includes and organizes right carbine arm up and down, assembling is provided with group to the support guide rod of carbine arm and support pedestal and constitute jointly, support guide rod wherein is provided with the guiding tooth bar, go up to the carbine arm be arranged on and the transmission case casing of the tooth bar engaged transmission that leads on, the worm gear that is driven by handwheel is set in the transmission case, and worm gear drives and guiding tooth bar meshed gears; Each to the carbine arm be two hinged settings, have and the spiral flute profile hook arm of arc anastomosis arc of spring, the flute profile of upper and lower carbine arm is oppositely arranged.
In above-mentioned overall technical architecture,, be provided with the location hook opposite between each two hook arm pin joint with being compressed the spring counter-force to the carbine arm for stablizing, firmly fix damping spring more.
The disclosed car independent suspension of the utility model device changer technical scheme, the deceleration transmission and the self-locking action of worm gear have been utilized, not only make transmission case very smooth and easy and flexible in the operation of guiding tooth bar, operated by handwheel is also very laborsaving and convenient, the latching characteristics of worm gear makes it need not additionally to be provided with self-locking device can make transmission case in the position compressed pendulum spring be finished effective self-locking, and it is reliable and make things convenient for; In addition, its up and down two groups can effectively control slot type arc spring hook arm and to be compressed the spring upper and lower end, implement stable fastening of multiple spot and control effect, thereby whether coaxial etc. with damper the dismounting of independent suspension device operation just no longer be subjected to its condition restriction, expand the suitable application area of the technical program changer, had reliable security performance.
Description of drawings
Fig. 1 is the utility model car independent suspension device changer scantling plan
Fig. 2 is that the A of Fig. 1 is to the part-structure schematic diagram
Fig. 3 is the B-B sectional structure chart of Fig. 2.
The specific embodiment
Accompanying drawing has provided car independent suspension device changer one typical case of the present utility model and has implemented structure.This changer includes and organizes right carbine arm 1,2 up and down, and assembling is provided with group to the support guide rod 3 of carbine arm 1,2 and support pedestal 4 and constitute jointly.Support guide rod 3 is provided with transmission case 5 engagements, for transmission case 5 provides the guiding tooth bar 6 of guiding up and down, goes up carbine arm 1 hinged the setting on transmission case 5 casings, down carbine arm 2 hinged being arranged at is supported on the pedestal 4.Two carbine arms of every pair of carbine arm 1,2 all have and the spiral corresponding arc of arc and firmly control the flute profile of spring of spring, the notch of two pairs of carbine arms 1,2 is oppositely arranged, press-fit top and bottom after every pair of carbine arm launches respectively, and can adjust the expansion degree of carbine arm according to the bore of pendulum spring in pendulum spring; Also be respectively equipped with a location hook 7,8 between upper and lower two pin joints to carbine arm 1,2.Go up on the hinged casing that is arranged at transmission case 5 of carbine arm 1, in its transmission case 5 worm gear is set, handwheel 9 is fixedly installed on the worm shaft 10, and the gear 12 that constitutes the duplex drives with worm gear 11 is provided with 6 engagements of guiding tooth bar.Rotation hand wheel 9 forward or backwards, under the drive of worm gear, gear 12 and 6 engagements of guiding tooth bar, drive transmission case 5 and on go up carbine arm 1, change and operations such as following relative distance, the loading of realization pendulum spring, compression, compression self-locking, decompression carbine arm 2.
Claims (2)
1, a kind of car independent suspension device changer, it is characterized in that this changer includes organizes right carbine arm (1,2) up and down, assembling is provided with support guide rod (3) and support pedestal (4) the common formation thereof of group to the carbine arm, support guide rod wherein is provided with guiding tooth bar (6), go up to the carbine arm be arranged on and transmission case (5) casing of the tooth bar engaged transmission that leads on, the worm gear that is driven by handwheel is set in the transmission case, and worm gear drives and guiding tooth bar meshed gears (12); Each to the carbine arm be two hinged settings, have and the spiral flute profile hook arm of arc anastomosis arc of spring, the flute profile of upper and lower carbine arm is oppositely arranged.
