Abstract

The utility model belongs to an operation tool for pin-type electrical appliance connector, in particular to a pneumatic pin remover which comprises an air cylinder (5), a firing pin (2), a reset buffer spring (3) and a return-limiting spring (4), a piston is arranged in the air cylinder (5), the front end of the piston is fixedly connected with the firing pin (2), the firing pin penetrates through the end cover of the air cylinder (5), the reset buffer spring (3) is arranged between the piston and the end cover of the air cylinder, the front part of the end cover of the air cylinder (5) is also provided with a pin collection tube (1); the rear end of the cylinder body of the air cylinder (5) is connected with an air control gun (7) through a transition connecting tube (6), the return-limiting spring (4) is arranged in the hollow cavity formed by the cylinder body of the air cylinder (5) and the transition connecting tube (6), and the air control gun (7) is connected with an air inlet pipe through a quick joint (8) of the air control gun. The pneumatic pin remover has reasonable design, simple structure, adopts the compressed air as power, drives the firing pin to push the pins to move out of the socket through the air cylinder, solves the problem that the manual pin remover has uneven force application and results in damaging the pin remover due to the vertical swinging, thereby improving the work efficiency.

Description

Pneumatic withdraw of the needle device

Technical field

The utility model belongs to contact pin type electric coupler spare power tool, mainly proposes a kind of pneumatic withdraw of the needle device.

Background technology

The attachment plug of electric locomotive control circuit, socket are when new system and maintenance, use (QX-01A type) manual standard withdraw of the needle device that contact pin is withdrawed from from socket, the 0.5mm but the anterior pipe thickness of this withdraw of the needle device is only had an appointment, during use by one-handed performance, thumb promotes striker forward and plays withdraw of the needle effect, and other four fingers are held body drive receipts finned tube and played the effect of contact pin receipts wing forward.One hand is finished two actions simultaneously and is easy to cause undue force or hand to shake, and then easily causes the anterior finned tube wall of receiving of withdraw of the needle device to fracture, and causes withdraw of the needle device to damage, can't use, and inefficiency.

The utility model content

The purpose of this utility model is to propose a kind of pneumatic withdraw of the needle device, exists withdraw of the needle device front portion to receive the problem that the finned tube wall fractures to solve manual standard withdraw of the needle device, and has the characteristics of high efficiency.

The utility model realizes that the technical scheme that its goal of the invention is taked is: a kind of pneumatic withdraw of the needle device, it mainly comprises cylinder, striker and reset buffer spring and retaining spring, has piston in the described cylinder, the front end and the striker of piston connect firmly, striker passes the end cap of cylinder, in order under cylinder promotes, contact pin is withdrawed from from socket, between piston and cylinder end cap, be provided with the reset buffer spring of ring set on striker, front portion at cylinder end cap also is provided with the receipts finned tube, its effect is when moving back contact pin the positioning reed of perk on the contact pin to be flattened, contact pin is withdrawed from from socket smoothly, and do not damage positioning reed and contact pin, socket, contact pin, socket can use repeatedly; Described cylinder block rear end is connected with the control air pressure gun by the transition tube connector, is provided with in the cavity of cylinder block and transition tube connector formation and prevents that striker from withdrawing from the retaining spring of receiving finned tube when resetting, and the control air pressure gun is connected with air inlet pipe by its snap joint.

The utility model is reasonable in design, simple in structure, utilize compressed air to be power, make the striker device promote contact pin by cylinder and from socket, withdraw from, having solved the operation of manual withdraw of the needle device exerts oneself inhomogeneously to cause withdraw of the needle device to teetertotter to cause damaging the problem of withdraw of the needle device, improved operating efficiency.

Embodiment

The embodiment that provides is in conjunction with the accompanying drawings further specified structure of the present utility model:

As shown in Figure 1, the utility model mainly comprises cylinder 5, striker 2 and reset buffer spring 3 and retaining spring 4, has piston in the described cylinder 5, the front end of piston and striker 2 connect firmly, have the two seals groove on the described piston and sealing ring is set, keeping sealing function when making the piston motion. striker 2 passes the end cap of cylinder 5, in order under cylinder 5 promotes, contact pin is withdrawed from from socket, wherein, striker 2 diameters have only about 3mm, about long 40mm, because draw ratio is excessive, piston and striker 2 are processed into one, difficulty of processing is big, engine lathe is difficult to processing, so utilize striker and piston brazing to be connected as a single entity. be provided with the reset buffer spring 3 of ring set on striker 2 between piston and the cylinder end cap, when cylinder promotion striker forward end moves, 3 cushioning effects of buffer spring reset, after finishing withdraw of the needle task, 3 striker reset responses of buffer spring reset. and also be provided with in the front portion of cylinder 5 end caps and receive finned tube 1, because it is big to receive finned tube 1 difficulty of processing, must be with instrument specialty machined into, so use primary standard withdraw of the needle device; Described cylinder 5 rear end of the cylinder block are connected with control air pressure gun 7 by transition tube connector 6, in the cavity of cylinder 5 cylinder bodies and transition tube connector 6 formations, be provided with and prevent that striker from withdrawing from the retaining spring 4 of receiving finned tube 1 when resetting, control air pressure gun 7 is connected with air inlet pipe by its snap joint 8, wherein transition tube connector 6 is to be used to connect cylinder 5 and control air pressure gun 7, because cylinder 5 external diameters directly are connected with control air pressure gun 7, after causing 7 tapping of control air pressure gun, tube wall is too thin, intensity difference, fragile, so adopt the transition tube connector 6 of reducing to connect, guarantee bonding strength, and sealing with fluid sealant in the junction, two ends. control air pressure gun 7 adopts the dedusting air pressure guns, and blowing mouth is removed, and processes connecting hole, adopting the dedusting air pressure gun mainly is because its compact conformation, in light weight, and hand-held convenient, control wind is easy. and whole the most of aluminium that adopts of instrument made, the instrument overall weight is only about 150 grams, easy to operate. during use, only need withdraw of the needle device alignment pin is pulled the air pressure gun button and can be withdrawed from contact pin.

The course of work of the present utility model is: hand-held control air pressure gun 7 is with the contact pin of striker 2 aligning plugs, and the switch of control control air pressure gun 7 makes compressed air enter cylinder 5, and striker 2 can withdraw from contact pin under cylinder 5 effects.
