Abstract
The utility model discloses an overhead automatic knife-change mechanical hand for a PCB (printed circuit board) drilling machine, which comprises a chuck, an up-down moving driving cylinder and a chuck control cylinder. The up-down moving driving cylinder is provided with a guide rail, the chuck adopts a clamping structure that a chuck nozzle is still and a needle taper sleeve can move, and a top spring and an ejector rod for jacking a knife handle are arranged in the chuck. By adopting the structure of the scheme, the overhead automatic knife replacing mechanical hand can ensure the up-down verticality of the cylinder, so as to ensure the consistency of the clamping part of a knife tool, thereby improving the moving precision. Meanwhile, the phenomenon that knife is not driven and pressed is ensured, and the knife tool can be stably put down.
Description
Technical field
The utility model relates to the mechanical device that is used for PCB rig automatic tool changer.
Background technology
Branch overhead and underneath type manipulator are arranged in the PCB rig.The overhead manipulator mainly contains two cylinders and drives, and cylinder control in top moves up and down, and mainly is to be operated by cylinder, and without any guiding, manipulator is tremnbled and chewed is to take, put cutter by following cylinder control.Underneath type manipulator principle is all similar: have only a cylinder control, structural design is ingenious, and element precision and mounting process require comparatively strict.The shortcoming of overhead manipulator is moving axially that clamping element is tremnbled and chewed when taking, putting cutter at present, is difficult to control the position of getting cutter, build-up of pressure, and the phenomenon of band cutter in addition, disposes two cylinder operation, and alignment be cannot say for sure to demonstrate,prove; The cost height.The manipulator shortcoming of underneath type is that inconvenience is installed, and cost is also high, and manufacturer's profit is few.
The utility model content
At the problems referred to above, the utility model aims to provide a kind of cutter accuracy and high overhead manipulator of reliability of taking, putting.
For realizing this technical purpose, scheme of the present utility model is: a kind of PCB rig automatic tool changer overhead manipulator, comprising tremnbles chews, one move up and down and drive cylinder, one and tremnble and chew control cylinder, the described driving cylinder that moves up and down also is provided with guide rail, the described push rod of tremnbling and also being provided with the top spring in chewing and being used to withstand handle of a knife, the employing mouth of tremnbling is motionless, the mode that the motion of pin tapered sleeve clamps.
The structure of this programme can guarantee cylinder perpendicularity up and down, improves kinematic accuracy; The uniformity that guarantees clamping cutter position guarantees not to be with cutter, not push type broach simultaneously; Cutter can be put down stably.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
As shown in Figure 1, manipulator of the present utility model is on original structure:
1, increases auxiliary guide rail, just can guarantee cylinder perpendicularity up and down, improved kinematic accuracy;
2, transformed the mode of action of clamping, interior bar is moved axially changed overcoat into and move axially, clamping is reliable, and retaining part is each all consistent, guarantees not to be with cutter, not push type broach;
3, in order to strengthen the flexibility of tremnbling and chewing, design the clamping cylinder, adopted the rod-pulling type piston, guaranteed the stationarity of two cylinders up and down;
4, for cutter can be put down stably, do not produce band cutter phenomenon, also increased top spring and push rod in chewing tremnbling.When putting cutter, tremnble to chew and open, tremnble chew in the top spring head on push rod, push rod heads on handle of a knife again, cutter has also just steadily put down.
The above; it only is preferred embodiment of the present utility model; not in order to restriction the utility model, every foundation technical spirit of the present utility model to any trickle modification that above embodiment did, be equal to and replace and improve, all should be included within the protection domain of technical solutions of the utility model.
Claims (1)
1. PCB rig automatic tool changer overhead manipulator, comprising tremnbles chews, one move up and down and drive cylinder, one and tremnble and chew control cylinder, it is characterized in that, the described driving cylinder that moves up and down also is provided with guide rail, described tremnbling chewed the clamping structure that moves for the motionless pin tapered sleeve of the mouth of tremnbling, and also is provided with top spring and the push rod that is used to withstand handle of a knife in this is tremnbled and chews.
