Abstract

The utility model relates to a special rotary trestle for repairing automotive engine, which belongs to the special tools in vehicle maintenance and repair work. The utility model comprises a rotary part, an oil tray part and an undercarriage, wherein, the rotary part is composed of a positioning pin 12 and a positioning pin holder 13 which are fixed on the channel steel base 14 of the oil tray part; the undercarriage is composed of an axletree 17 which is installed on the channel steel base 14 of the oil tray part through a U-shaped clamp 15 and a screw nut 16. The engine assembly is clamped on a special rotary trestle and is capable of rotating optionally within 360 DEG., which result in the optional work of repairing and dismounting. The components and greasy dirt can be concentrated in the oil tray, which avoids the pollution of the ground and the loss of the components. The utility model has low labor intensity and high efficiency.

Description

Automobile engine is repaired special-purpose swivel mount

The utility model is a kind of specific purpose tool in the automobile engine maintenance process.Be applicable to the east wind that China is a large amount of, automobile engines such as liberation are when disassembling place under repair, and facility are rotated in the novel maintenance special use that keeps the clean health in work-yard to design with preventing parts from losing.

At present in a large amount of auto repair workshop of China, all be that engine stripping is placed on place under repair and parts dismounting on the ground, engine assembly is because the parts of forming are various, and is relatively heavier, and repairing needs several people to stir back and forth often tens times, just can be accomplished, very inconvenient, labour intensity is big, and efficient is low, even cause greasy dirt completely, influence the workplace environmental sanitation.

The purpose of this utility model is: engine assembly is clamped on the special-purpose swivel mount, can carries out any rotation in the 360 deg, make the work that removes and installs arbitrarily carry out, parts and greasy dirt can concentrate in the food tray, avoid place pollution and parts to lose, and the utility model has adopted the reassembling type assembling, and is removable to minimum volume.

The utility model is achieved in that the utility model comprises rotating part, food tray part and walking mechanism three parts.After automobile engine assembly disassembles, (generally all there is portal jib crane in big workshop by special hanger, little maintenance worker-house available dedicated suspender such as hand-hydraulic telpher) engine assembly is hung on the swivel mount, by four manual lead screws on the swivel mount and screw mandrel footstock engine assembly is fixed.Swivel mount is located on the food tray, rotates automatically for preventing swivel mount, by the alignment pin pinning.The beneath of food tray is running gear, according to the workplace situation, engine assembly can be pushed away toward any work and carry out maintenance work in the place easily; Needs according to maintenance operation, as long as alignment pin is taken out, on the plate rail of the steel pipe garden of swivel mount, turn to needed maintenance position with handgrip gently, use the alignment pin pinning again, then can reach and make engine assembly rotation and convenient purpose of keeping in repair arbitrarily, the small-sized parts that disassemble from engine assembly can be placed in the food tray of below conveniently in order to prevent loss.

Advantage of the present utility model is: adopt assembly type on the structure, can split into minimum volume, carry and assemble easy-to-use, to east wind, the different engine assembly of liberation vehicle, as long as change engine assembly standing parts such as crossbeam at vehicle, then can satisfy the maintenance of two kinds of vehicles, because rotating part does not adopt complicated electric shift system, adopt the fixing mode of alignment pin, simple and easy, steel pipe garden plate rail rotates gently on the swivel mount as long as hold, then can rotate to the optional position of being convenient to maintenance work, food tray partly makes the machine oil of engine assembly and wash oil can splash into food tray, and small-sized parts are put into food tray after can dismantling conveniently, with anti-lost.
