The invention discloses a locating and clamping mechanism, which is characterized by comprising a high, middle and low-level oil cylinder (1), a secondary step wedge-shaped iron (2), a tray jacking mechanism (3) and a position feedback mechanism (4); the high, middle and low-level oil cylinder (1) comprises a piston rod; the high, middle and low-level oil cylinder (1) is connected with the secondary step wedge-shaped iron (2) through the piston rod; the secondary step wedge-shaped iron (2) is in contact with the tray jacking mechanism (3); the position feedback mechanism (4) is connected with the horizontal tail end of the secondary step wedge-shaped iron (2). According to the locating and clamping mechanism disclosed by the invention, matching action is performed by the high, middle and low-level oil cylinder, the wedge-shaped iron and a tray to realize secondary stroke so as to finish cutter relieving, and moreover, a workpiece is finally clamped to finish a working cycle; the integral device is compact in structure, the locating accuracy is very high, the assembly is simple, the cost is greatly reduced, and the work efficiency is greatly improved.
Description
Technical field
The invention belongs to machining equipment technical field, particularly a kind of positioning and clamping mechanism.
Background technology
Boring operation boring compound wall in general machine tooling process, process is: before bore hole, boring bar to be penetrated guider, and make on knife bar many in boring cutter often the processing wall of cutter on every layer of wall, enter wait state, then main shaft has turned and has started processing work.Mechanism arrangement in the past is mainly divided into two parts, and one is gear, rack gear, and workpiece is raised to centre and allows cutter position, boring bar enter and to penetrate guider, travel switch is issued an order again; Workpiece is raised up to final Working position by dual-purpose drift clamp system again, and clamping is started working.The lifting mechanism build of this rack-and-pinion associating wedge shape iron is huge, and structure is loaded down with trivial details, and positioning precision is relatively low, can not ensure higher required precision again, have impact on operating efficiency greatly.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of positioning and clamping mechanism, and this positioning and clamping mechanism is used for the location clamping of lifting for twice in Boring, and structure is simple, simple operation.
A kind of positioning and clamping mechanism, comprises senior middle school's low level oil cylinder, twice step wedge shape iron, pallet lifting body and position feedback mechanism; Senior middle school's low level oil cylinder comprises piston rod, and senior middle school's low level oil cylinder is connected with twice step wedge shape iron by piston rod, and twice step wedge shape iron touches mutually with pallet lifting body, and described position feedback mechanism is connected with the horizontal end of twice step wedge shape iron.
As the further improvement of technique scheme, described senior middle school low level oil cylinder also comprises cylinder barrel mobile piston, and cylinder barrel is divided into left chamber, lumen and right chamber, and left chamber and right chamber intersection are provided with confined planes, and mobile piston is fixed on described piston rod right-hand member.
Another kind as technique scheme improves, and described twice step wedge shape iron is provided with wedge shape iron, and wedge shape iron is divided into a high position, meta and low level three operating positions.
Another kind as technique scheme improves, and described pallet lifting body bottom is provided with roller, and roller rolls at the contact surface of wedge shape iron.
Another kind as technique scheme improves, and described position feedback mechanism comprises extension bar and travel switch, and described extension bar one end is connected with wedge shape iron, and the other end is provided with travel switch, the extension bar touching travel switch when wedge shape iron arrives assigned address.Position feedback mechanism not only plays the effect that travel switch is issued an order, and accurately confirms workpiece physical location, prevents from hitting cutter, plays the effect of safeguard protection.
Senior middle school's low level oil cylinder of positioning and clamping mechanism of the present invention, wedge shape iron and pallet cooperatively interact action, realize secondary stroke, to complete middle cutter relieving, and last clamping work pieces, circulation of finishing the work.First make workpiece be raised to centre by the stroke calculated and allow cutter position, after waiting boring bar to penetrate guider, then make workpiece secondary be raised up to locating surface by the stroke designed and by Workpiece clamping, both structure is reduced like this, make again positioning precision improve, assembling is simple, and cost reduces greatly.And positioning precision is very high, assembling letter drastically increases operating efficiency.
Accompanying drawing explanation
Fig. 1 is positioning and clamping mechanism structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of positioning and clamping mechanism that the present invention proposes is described in detail.
As shown in Figure 1, positioning and clamping mechanism comprises senior middle school's low level oil cylinder 1, twice step wedge shape iron 2, pallet lifting body 3 and position feedback mechanism 4; Senior middle school's low level oil cylinder 1 comprises piston rod, cylinder barrel mobile piston, and cylinder barrel is divided into left chamber, lumen and right chamber, and left chamber and right chamber intersection are provided with confined planes, and mobile piston is fixed on described piston rod right-hand member.Senior middle school's low level oil cylinder 1 is connected with twice step wedge shape iron 2 by piston rod, and twice step wedge shape iron 2 touches mutually with pallet lifting body 3, and described position feedback mechanism 4 is connected with the horizontal end of twice step wedge shape iron 2.Described twice step wedge shape iron 2 is provided with wedge shape iron, and wedge shape iron is divided into a high position, meta and low level three operating positions.Described pallet lifting body 3 bottom is provided with roller, and roller rolls at the contact surface of wedge shape iron.Described position feedback mechanism 4 comprises extension bar and travel switch, and described extension bar one end is connected with wedge shape iron, and the other end is provided with travel switch, the extension bar touching travel switch when wedge shape iron arrives assigned address.
The course of work is: senior middle school's low level oil cylinder 1 oil-feed, and piston rod drives wedge shape Railway transportation to move, thus pallet is moved up and down, and reaches cutter relieving and the object of clamping.When left chamber and the oil-feed simultaneously of right chamber of senior middle school's low level oil cylinder 1, piston rod moves from left to right, the roller of pallet lifting body 3 starts " climbing step ", when move to centre allow cutter position time, pallet keeps temporary stop, position feedback mechanism 4 sends instruction, confirm pallet physical location, boring bar feed, after penetrating guider Deng boring bar, outside PCL program sends instruction, senior middle school's low level oil cylinder 1 is allowed to only have the oil-feed of left chamber, such piston rod promotes wedge type iron again, pallet is lifted again, until workpiece props up clamp top locating surface, finally complete pinching action.
