Abstract
The utility model discloses an internal pulling horse, which is composed of a feed screw, a supporting rack which is sheathed with the feed screw through a bearing, a pulling claw which is arranged on the lower part of the feed screw, etc. The internal pulling horse is characterized in that a supporting rod is fixed on the supporting rack; the pulling claw is hinged with an ear iron through a hinging shaft, and the ear iron is sheathed with the feed screw through screw threads; the upper end of the feed screw is provided with a twisted rod, and a claw-fixing disc is arranged on the lower end of the ear iron. The utility model has the advantages of a simple structure, reasonable design, convenient operation, time saving, labor saving, convenience for carrying, and no damage of work pieces. The internal pulling horse, which has the advantage that the supporting rod and the pulling claw both adopt triangular structures of stable balancing and homogeneous stress, can adapt to internal sleeve field stripping with different diameters, and can be quickly dismounted and assembled; internal pulling horse is especially suitable for middle-small repair plants.
Description
The utility model relates to a kind of Internal drawing horse that is applicable to the dismounting object, and it is particularly suited for the dismounting of all kinds of cylinder sleeves, interior cover.
In internal combustion engine, air compressor and other repair of machine industries, often there are all kinds of cylinder sleeves, interior overcoat and similar accessory need repair replacing, when hand-power can not unload when getting, the way that often adopts hammer to add the cushions and knock, the easy damaged parts are also wasted time and energy; Or make slow-witted pull head and be equipped with leading screw, supporting plate and supporter and pull out, but can only adapt to and the measure-alike accessory of slow-witted pull head, the scope of application is little, and discontinuity is also heavy; Or utilize the special pressure machine to extrude, but this equipment volume is big, price is high, is difficult for popularizing.
The purpose of this utility model be exactly provide in order to solve existing weak point in the prior art a kind of simple and reasonable, practical and convenient, the scope of application is wide, the Internal drawing horse that is easy to promote.
The purpose of this utility model realizes by following measure:
Pulling claw that the utility model is contained in the bracing frame on the leading screw and is arranged on the leading screw bottom by leading screw with by bearing holder (housing, cover) etc. is formed, it is characterized in that: on bracing frame, be fixed with at least two poles of extending downwards, pulling claw is hinged by hinge and ear iron, thread set is crossed on leading screw by the ear Tie Tong, the upper end of leading screw is provided with stirs thick stick, decides the pawl dish and relies on the lower end that is threaded in ear iron.
In the utility model, bracing frame is sleeved on leading screw top by thrust bearing.The quantity of pole is preferably three, between bracing frame and the pole by being threaded.The quantity of pulling claw is preferably three, and the angle between three pulling claws is 120 °.
The utility model compared with prior art has following advantage: pole and pulling claw all adopt triangular structure, balance and stability, stressed even, simple in structure, reasonable in design, easy to use, time saving and energy saving, do not damage parts, displacement adjusting pulling claw is flexible up and down to decide the pawl dish, can adapt to the interior cover field-strip of different-diameter.Because therefore all quickly-detachables, assembling between each parts in the utility model be convenient to keeping and carried, and is specially adapted to medium and small repair shop.
Accompanying drawing is the utility model structural representation.
The utility model is done with detailed description below in conjunction with accompanying drawing:
As shown in the figure: three pulling claws (7) that this Internal drawing horse is sleeved on the bracing frame (3) on the leading screw and is arranged on the leading screw bottom by leading screw (1) with by thrust bearing (4) etc. are formed, wherein go up by screw thread and be fixed with three poles (5) of extending downwards at bracing frame (3), pulling claw (7) is hinged by hinge (8) and ear iron (6), ear iron (6) by thread set on leading screw (1), the upper end of leading screw is provided with stirs thick stick (2), decide pawl dish (9) by on the ring platform that is threaded in the leading screw lower end and processes, deciding also to be processed with the dial hole on the pawl dish, be used to regulate the position of deciding the pawl dish.
The utility model places three poles and intends pulling out accessory periphery suitable for reading in use, and three pulling claws stretch into and tangle interior cover in the chamber, stirs to decide the pawl dish and tighten up pulling claw, rotates to stir thick stick and interior cover can be pulled out slowly.Reverse use also can be carried out insert and draw in operation.
