A kind of automatic screw machine
Technical field
The present invention relates to the appliance switch element field, is a kind of automatic screw machine of realizing that screw and binding post are installed automatically specifically.
Background technology
At present, all be equiped with binding post in the electric switch that people generally use, and all be connected with trip bolt on the binding post.Yet the assembling of existing binding post and trip bolt all is that staff is installed.Its operation is to position operation with artificial pairs of posts and trip bolt earlier, spins with pneumatic screwdriver then.This mounting means exists two significant deficiency: one, binding post and trip bolt location are one to one, so in assembling process, need to waste great amount of manpower, particularly under situation about producing in enormous quantities, the efficient of its assembling is very low, can not adapt to the production demand that electric switch increases day by day; They are two years old, being connected to of binding post and trip bolt spins, it generally is to realize with pneumatic screwdriver after finish binding post and trip bolt location, and utilize staff to position in the process of operation, be easy to occur phenomenons such as the screw thread dislocation of binding post and trip bolt, the back trip bolt inclination that spins, its percent defective is higher.In addition, staff position and the site error of the mounting means that spins bigger, the less stable after the installation.Therefore, the assembling device of binding post and trip bolt all awaits further improvement at present.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of simple in structure, efficiency of assembling is high and the automatic screw machine of good reliability.
Goal of the invention of the present invention is achieved in that a kind of automatic screw machine, it is characterized in that: described automatic screw machine comprises base, is located at tray, cantilever and pedestal on the base respectively, pedestal is provided with worker's mould, and have a locating slot that matches with screw and binding post shape, locating slot is communicated with worker's mould, pedestal is provided with position and the corresponding jack unit of locating slot, tray is provided with and the corresponding chute in locating slot position, and cantilever is provided with and the corresponding device that spins in worker's mould position.
Described worker's mould comprises die body, be located at clamping element on the die body, be opened in being used on the pedestal holds the lower mode cavity of binding post and is opened in the upper cavity that is used to hold screw in the die body, and upper cavity is an inclined hole.
Have the side opening that is communicated with upper cavity on the side of described die body.
Described side opening is located at the upper cavity top.
The described device that spins comprises the slide rail that is located on the cantilever side and is located at the jack unit of cantilever top, and jack unit and is located on the slide rail and can be connected along the slide block that slide rail comes and goes slip, and slide block is provided with the element that spins.
Described jack unit is a cylinder.
The described element that spins is the disengaging type pneumatic screwdriver.
Described tray is the oscillatory type transfer dish.
The top of described locating slot is provided with supervising device.
Described supervising device is installed on the pedestal.
Automatic screw machine of the present invention improves prior art, by tray, chute, locating slot and the worker's mould that is interconnected is set on base, and on base the spin cantilever of device of mounting strap, the transmission of binding post and screw, locate and spin and realize full automatic working fully, saved the manpower in the assembling process greatly.In addition, the location of binding post and screw and assembling all realize in mould, can effectively improve phenomenons such as the screw thread dislocation of binding post and trip bolt, the back trip bolt inclination that spins, and have improved the yield rate of product.In addition, the transmission of binding post and screw, to locate and spin be pure machine driving and installation, and its efficiency of assembling is higher, and being provided with supervising device on the screw machine automatically, can monitor the ruuning situation of machine at any time, thereby the reliability of its assembling is stronger.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to the accompanying drawings 1, shown in accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5 and the accompanying drawing 6, automatic screw machine of the present invention mainly comprises base 1, tray 2, cantilever 3 and pedestal 4, tray 2, cantilever 3 and pedestal 4 all are located on the base 1, more smooth and easy for the transmission that makes screw and binding post, tray 2 can adopt the oscillatory type transfer dish.Pedestal 4 is provided with worker's mould 5 and locating slot 6, and locating slot 6 matches with screw and binding post shape, size respectively, and worker's mould 5 and locating slot 6 are connected.Pedestal 4 is provided with jack unit 7, and jack unit 7 positions are corresponding with locating slot 6.Tray 2 is provided with chute 8, and chute 8 is corresponding with locating slot 6 positions.Cantilever 3 is provided with the device 9 that spins, and device 9 positions that spin are corresponding with worker's mould 5.Worker's mould 5 of the present invention mainly is made up of die body 51, clamping element 52, lower mode cavity 53 and upper cavity 54, and clamping element 52 is located on the die body 51.Lower mode cavity 53 is opened on the pedestal 4, and can hold binding post; Upper cavity 54 is opened in the die body 51, and can hold screw.Upper cavity 54 is an inclined hole, and this structure is convenient to screw and can be moved down smoothly when moving to upper cavity 54, guarantees that the phenomenon of bail can not appear in the screw transmission.Have side opening 55 on the side of die body 51, side opening 55 is communicated with upper cavity 54, and side opening 55 is located at upper cavity 54 tops.By the positioning action of worker's mould 5, binding post and screw can dock accurately, make things convenient for the user to assemble, and have improved the reliability that screw spins, and reduce the percent defective of goods, have improved the efficient of binding post and screw assembling.The device 9 that spins comprises slide rail 91 and jack unit 92, and slide rail 91 is located on the side of cantilever 3; Jack unit 92 then is fixedly mounted on cantilever 3 tops.Slide rail 91 is provided with slide block 93, and this slide block 93 can come and go along slide rail 91 and slide, and fixedlys connected with jack unit 92 in the top of slide block 93, and a side of slide block 93 is fixed with the element 94 that spins.In order to make the roof pressure action more smooth, jack unit 92 can adopt cylinder, and the element 94 that spins is the disengaging type pneumatic screwdriver, can make the action that spins more smooth.Monitor the ruuning situation of automatic screw machine for the convenience of the users, the top of locating slot 6 is provided with supervising device 10, and this supervising device 10 is fixedly mounted on the pedestal 4.
Above-mentioned specific embodiment only is the effect of the present invention specific embodiment preferably, and the identical or automatic screw machine structure that is equal to of structure all and of the present invention is all in protection scope of the present invention.
