Abstract
The utility model discloses a locking-mode device of a high-speed precision punching machine, which comprises an oscillating rod. The outer surface of the oscillating rod is screwed with a pressing block through threads matched with the outer surface of the oscillating rod; a sleeve is sleeved with the outer surface of the pressing block, and the outer surface of the pressing block and the inner surface of the sleeve are provided with cavities for containing hydraulic oil; the side wall of the sleeve is provided with an oil inlet hole connected with an oil pump. In the utility model, through hydraulic locking mode, the oil pump can immediately supply oil after the pressure is reduced due to long-term use, thereby leading an oscillating head to be always in locked state.
Description
Technical field
The utility model relates to a kind of dieing machine, relates in particular to a kind of clamping apparatus of dieing machine.
Background technology
It is strong that high speed accurate numerical control press has whole rack construction rigidity, internal stress is little, the punching precision height, be fit to continuous punching production, can operate advantages such as the temperature position is little in 24 hours, be widely used in fields such as household electrical appliances, automobile, five metals, electronics, during the pressed sheet band, utilize high speed accurate numerical control press, lasting feeding along with the reciprocal high-speed motion and the blank of drift, the drift of this kind punch press and mould can strike out the shape that mould limits with the blank that is placed on the workbench, finish the punch forming work of continuous blank.
The clamping apparatus of current high speed accurate numerical control press comprises yaw, the outer surface of described yaw is arranged with a sleeve, offer a screwed hole on the sidewall of described sleeve, twist in the screwed hole and establish bolt, the end of bolt leans on the sidewall of yaw, thereby yaw is locked, plant long-time use of clamping apparatus of structure like this after, loosening phenomenon can appear in bolt, thereby causes the yaw can not be by effectively locked.
The utility model content
The purpose of this utility model provides a kind of clamping apparatus of dieing machine, and this clamping apparatus can make yaw be in by locking state always.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of clamping apparatus of dieing machine, comprise fork, the outer surface of described fork is twisted by the screw thread that cooperatively interacts and is provided with briquetting, the outer surface of described briquetting is arranged with sleeve, the outer surface of this briquetting and the inner surface of sleeve have the cavity that holds hydraulic oil, also be provided with fuel feed hole on the sidewall of described sleeve, described fuel feed hole connects oil pump.
In the technique scheme, the screw thread that the outer surface of described fork cooperates with the briquetting inner surface is a trapezoidal thread.Be arranged to trapezoidal thread, more can effectively prevent the relative slippage of fork with briquetting.
In the technique scheme, be provided with sealing ring between the outer surface of described briquetting and the inner surface of sleeve.Thereby can prevent effectively that hydraulic oil from oozing out from the outer surface of briquetting and the inner surface of sleeve.
The utility model compared with prior art has following beneficial effect:
The utility model is by the hydraulic pressure locked mode, and after long-time the use, after pressure reduced, oil pump can continue fuel feeding at once, thereby yaw is in by locking state always.
Description of drawings
Fig. 1 is installed on the structural representation of dieing machine for the utility model.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1～Fig. 2, the clamping apparatus of dieing machine comprises fork 1, and the lower end of described fork 1 is provided with the bulb 7 that cooperates with slide block 9, and the outer surface of described fork 1 is twisted by the trapezoidal thread that cooperatively interacts and is provided with briquetting 3.
The outer surface of described briquetting 3 is arranged with sleeve 5, and the inner surface of the outer surface of this briquetting 3 and sleeve 5 has the cavity 52 that holds hydraulic oil, also is provided with fuel feed hole 50 on the sidewall of described sleeve 5, and described fuel feed hole 50 connects oil pump (oil pump is not shown).
Upper and lower corresponding to cavity 52 between the inner surface of the outer surface of described briquetting 3 and sleeve 5 is provided with " O " shape sealing ring 9.
During work, oil pump work enters hydraulic oil in the cavity 52 between the inner surface of the outer surface of briquetting 3 and sleeve 5 by fuel feed hole 50, thereby it is briquetting 3 is locked, because briquetting 3 and fork 1 cooperate by trapezoidal thread, both can not move mutually, also are that fork 1 is by locked.
