Also be provided with the briquetting that is positioned at the workbench top; Said briquetting is connected with the vertical piston rod of vertical hydraulic cylinder through connecting crossbeam; Said vertical hydraulic cylinder comprises two and be symmetrically set in the workbench both sides, the free end of said vertical piston rod be connected crossbeam and connect, briquetting is positioned at and connects the crossbeam middle part.
The beneficial effect of the utility model is:
1. adopt hydraulic power as driving source, and the flexible of hydraulic power piston rod only need realize that be common practise of the prior art, operation is very easy through reversal valve and being connected of oil cylinder, need not any unnecessary manual labor;
2. simple mechanical transmission component such as hydraulic drive mate gear, tooth bar is realized compressing and unclamping of workpiece on the horizontal direction, and structural principle is simple, realizes easily;
3. cooperate with the hydraulic cylinder of vertical direction, can realize compressing on the vertical direction equally.
Description of drawings
Fig. 1 is one of structural representation of the utility model;
Fig. 2 be the utility model structural representation two.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Embodiment: referring to Fig. 1.
A kind of hydraulic control mechanical type hold down gag; Comprise workbench 1; Be cavity between the deck plate 2 of said workbench 1 and the base plate 3, the top of said workbench 1 is provided with horizontal hydraulic cylinder 4, and the lower surface of the horizontal piston bar 5 of said horizontal hydraulic cylinder 4 is a tooth bar; First spur gear, 6 engagements in said tooth bar and workbench 1 cavity; Said first spur gear 6 belows are provided with sliding rack 7, the upper surface of said sliding rack 7 and 6 engagements of first spur gear, and the base plate 3 of the lower surface of sliding rack 7 and workbench 1 rolls or is slidingly matched; Said first spur gear 6 outsides are provided with second spur gear 8 with the engagement of sliding rack 7 upper surfaces; Said second spur gear 8 outsides are provided with the 3rd spur gear 9 with its engagement, and said the 3rd spur gear 9 separates with sliding rack 7, and said the 3rd spur gear 9 tops are provided with the extruding tooth bar 10 with its engagement; The deck plate 2 of said workbench 1 is provided with the extruding tooth bar guide pad 11 that has chute, and said extruding tooth bar 10 slides in extruding tooth bar guide pad 11 and separates with second spur gear 6.
The operation principle of the utility model is summarized as follows:
Workpiece is positioned on the deck plate 2 of workbench 1 between the extruding tooth bar 10 and horizontal piston bar 5, the operation hydraulic system, the horizontal piston bar 5 of horizontal hydraulic cylinder 4 is stretched out, and (this is a common practise; Do not give unnecessary details); Then each parts of the utility model hold down gag will can be realized Work-sheet pressing according to direction motion shown in Figure 1, and overflow valve and pressure gauge can be set on hydraulic circuit; The force value of reservation is set; Overflow valve is opened when reaching the certain pressure value, and is excessive to avoid circuit pressure, each parts in the damage device.
