Description
Technical field
The present invention relates to a kind of hold-down mechanism, particularly relate to double hold-down mechanism.
Background technology
Current work pieces process is generally after work pieces process is complete, unloads workpiece, is loaded on after workpiece and continues processing, and for this waste man-hour, working (machining) efficiency is low, and proposition double clamp system, can effectively deal with problems.
Utility model content
The object of the invention is to solution to stop lathe workpiece loading and unloading, effectively can not improve the utilization rate of lathe, the present invention proposes double clamping structure for this problem, another workpiece can be loaded and unloaded when machine tool processing workpiece, the lifting of implementation efficiency.
For the problems referred to above, the present invention proposes following scheme: a kind of double hold-down mechanism, comprise body, cylinder, briquetting, first performs gear, first connecting rod, travelling gear, second connecting rod, second performs gear, pore, tooth bar, driven wheel, the piston rod of cylinder connects tooth bar, tooth bar engages with driven wheel, travelling gear is coaxial with driven wheel, travelling gear both sides and first perform gear and second and perform gears meshing, first execution gear and second performs one end that gear is connected first connecting rod and second connecting rod respectively, first connecting rod is connected briquetting respectively with the other end of second connecting rod, first spacing performed between gear and the second execution gear is greater than the length of connecting rod, the four points of connection at first connecting rod and second connecting rod two ends connects into parallelogram.
In such scheme, when the pore air inlet near tail cylinder, piston rod band carry-over bar moves forward, tooth bar just drives driven wheel engaged transmission, the travelling gear coaxial with driven wheel rotates, at execution gear and the execution pinion rotation of the wheel both sides of driving, be fixed on and perform gear and the first connecting rod performed on gear and second connecting rod rotation, the rotating band dynamic pressure block of first connecting rod and second connecting rod planar moves, because first performs the length that gear and second performs the large and first connecting rod of spacing between gear and second, and the four points of connection at first connecting rod and second connecting rod two ends connects into parallelogram, therefore briquetting planar moves in parallel.
Further optimization, boss moves in groove, can be limited the range of movement of tooth bar, prevent tooth bar from engaging with driven wheel and come off by two edges of groove.
Further optimization, two numbers of teeth performing gear are identical, can ensure that the anglec of rotation of two connecting rods is identical, realize moving in parallel of briquetting.
Further optimization, first performs gear, travelling gear, second performs gear, driven wheel is all be connected on body by sliding bearing, and the required precision in this mechanism is not high, and use sliding bearing, cost is low.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is that double hold-down mechanism of the present invention is always schemed;
Mark in above-mentioned figure is: first performs gear 1, first connecting rod 2, travelling gear 3, second connecting rod 4, second execution gear 5, body 6, pore 7, cylinder 8, tooth bar 9, driven wheel 10, briquetting 11.
Detailed description of the invention
As shown in Figure 1, double clamp system, comprising embodiments of the present invention: first performs gear 1, first connecting rod 2, travelling gear 3, second connecting rod 4, second execution gear 5, body 6, pore 7, cylinder 8, tooth bar 9, driven wheel 10, briquetting 11.
The piston rod of cylinder 8 connects tooth bar 9, tooth bar 9 engages with driven wheel 10, travelling gear 3 is coaxial with driven wheel 10, travelling gear 3 both sides and first perform gear 1 and second and perform gear 5 and engage, first execution gear 1 and second performs one end that gear 5 is connected first connecting rod 2 and second connecting rod 4 respectively, the other end hinged briquetting 11 respectively of first connecting rod 2 and second connecting rod 4.
First performs gear 1, gear 3, second performs gear 5, driven wheel 10 is all be fixed on body 6 by axle.
When pore 7 air inlet near cylinder 8 afterbody, piston rod band carry-over bar 9 moves forward, fluted in the plane that tooth bar 9 moves, tooth bar 9 end is provided with boss, boss moves in groove, tooth bar just drives driven wheel 10 engaged transmission, the travelling gear 3 coaxial with driven wheel 10 rotates, the first execution gear 1 in wheel 3 both sides of driving and the second execution gear 5 rotate, be fixed on the first execution gear 1 and second and perform first connecting rod 2 on gear 5 and second connecting rod 4 rotates, the rotating band dynamic pressure block of first connecting rod 2 and second connecting rod 4 planar moves, because the spacing between the first execution gear 1 and the second execution gear 5 is large and the length of connecting rod, and the four points of connection at first connecting rod 2 and second connecting rod 4 two ends connects into parallelogram, when pore 7 air inlet of cylinder 8 other end, above-mentioned transmission is by counter motion, realize the clamping of opposite side workpiece, operating personnel can complete unloading and dress of workpiece simultaneously.
This double clamping mechanism can be raised the efficiency, and can realize while machine tooling part, and operator, to the handling of another station part, can effectively raise the efficiency.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
