Abstract
The utility model discloses a tool for pulling out a locating pin in order to solve the problems that time and labor are consumed due to the fact that no special tool for pulling out the locating pin exists currently. The tool is composed of a sliding rod, a sliding block and a pin-pulling connector. The sliding block is installed on the sliding rod and near the tail portion of the sliding rod, the sliding block is sleeved on the sliding rod and can slide along the sliding rod, a screw hole is formed in the head end of the sliding rod, the pin-pulling connector is formed by two screws in a butt joint mode, the screw at one end is screwed into the screw hole in the head end of the sliding rod, the screw at the other end is screwed into a locating pin, the pin-pulling connector has various specifications according to the size of the screw which is connected with the locating pin, and the pin-pulling connector and the sliding rod are connected and used in an alternating mode. When the tool is in use, the sliding block is sleeved on the sliding rod firstly, then one end of the pin-pulling connector is connected to the sliding rod, the other end of the pin-pulling connector is connected inside the locating pin, and at last the sliding block is pushed to slide to impact the sliding block on the sliding rod, and therefore the purpose of pulling out the locating pin is achieved. Moreover, locating pins with different sizes can be pulled out through the method of choosing pin-pulling connectors with different specifications, time and labor are saved, and working efficiency is high.
Description
Technical field
The utility model relates to a kind of alignment pin puller.
Background technology
In the maintenance of diesel locomotive transmission case, there are many alignment pins to extract, but do not have special-purpose puller.Present way is at screw of screwdriver front end welding, with in the screw precession alignment pin, beats the screwdriver afterbody with hammer then, and alignment pin is extracted.The shortcoming of this way is the alignment pin that a screwdriver can only be extracted a kind of specification, and because discontinuity when beaing, screwdriver is easy to damage, and wastes time and energy.
Summary of the invention
The purpose of this utility model is to overcome the prior art defective, and a kind of alignment pin puller is provided.
The technical solution of the utility model is achieved in that a kind of alignment pin puller, it is: it is made up of slide bar, slide block and the joint of pulling pin, be equipped with block near afterbody on the slide bar, slide block set also can slide along slide bar on slide bar, the slide bar head end has screw, the joint of pulling pin is formed by two screw rod butt joints, and an end screw rod precession slide bar head end screw is in the other end screw rod precession alignment pin.
Preferably, the joint of pulling pin is connected replacement with slide bar and uses by the different plurality of specifications that have of screw size that link to each other with alignment pin.
When the utility model uses earlier with slide block set on slide bar, joint one end of will pulling pin again is connected on the slide bar, the other end is connected in the alignment pin, the final force sliding slider, impact the block on the slide bar, reach the purpose that alignment pin is extracted, and can extract the alignment pin of different size by the joint of pulling pin of selecting different size for use, time saving and energy saving, high efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, the 1-slide bar; The 2-block; The 3-slide block; The 4-joint of pulling pin.
The specific embodiment
Be further described below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of alignment pin puller, it is made up of slide bar 1, slide block 3 and the joint 4 of pulling pin, and is equipped with block 2 near afterbody on the slide bar 1, slide block 3 is enclosed within on the slide bar 1 and can slides along slide bar 1, slide bar 1 head end has screw, and the joint 4 of pulling pin is formed by two screw rod butt joints, and an end screw diameter is fixed, in the precession slide bar 1 head end screw, other end screw diameter is divided into 4cm, 5cm, 6cm, 8cm and five kinds of specifications of 10cm, in the precession alignment pin, satisfies the needs of extracting different alignment pins.
When using, the utility model earlier slide block 3 is enclosed within on the slide bar 1, joint 4 one ends of will pulling pin again are connected on the slide bar 1, the other end is connected in the alignment pin, final force sliding slider 3, impact the block 2 on the slide bar 1, reach the purpose that alignment pin is extracted, and can extract the alignment pin of different size by the joint 4 of pulling pin of selecting different size for use, time saving and energy saving, high efficiency.
