Description
Technical field:
The utility model relates to twin polishing/lapping machine field, relates in particular to the structure of the pilot pressure of disc system on twin polishing/lapping machine with cylinder.
Background technique:
The pressure control of electronics special processing equipment Twp-sided polishing machine adopts pneumatic control usually, and cylinder is usually as executive component.The air cylinder that adds of traditional polissoir adopts common cylinder or low friction cylinder usually, is the standard cylinder.Because the Environmental Conditions of twin polishing/grinding equipment is had relatively high expectations to cleanliness, equipment uses in clean room usually, and therefore the height to equipment limits to some extent, and actuating pressure is required accurately steadily.In actual production, if adopt the standard cylinder that can purchase on the market, pressure precision, physical dimension, the clean requirement that requires all can not satisfy the technology use.
Summary of the invention:
The purpose of this utility model is to avoid the deficiencies in the prior art, provides a kind of compact type sensitive cylinder.To solve, realize accurate control simultaneously to last disc system pressure because of adopting the standard cylinder to cause the too high and problem not easy to clean of device height.
For achieving the above object, the technological scheme that the utility model is taked is: the sensitive cylinder of a kind of compact type, including cylinder back cover (1), cylinder protecgulum (9) is connected with cylinder barrel (13) respectively, cylinder barrel (13) is provided with upper vent (15) piston rod (8) and is provided with piston (5), and its main feature is to include to be provided with on cylinder back cover (1) with master cylinder to be connected with tapped hole (2).
The sensitive cylinder of described compact type, the rod end of described piston rod (8) is provided with the rod end screw thread that is connected with pulling force sensor.
The sensitive cylinder of described compact type is provided with cushion pad (14) between described cylinder back cover (1) and piston (5); Between cylinder protecgulum (9) and piston (5), be provided with cushion pad (7) down.
The sensitive cylinder of described compact type is provided with piston packing (6) on described piston (5).
The sensitive cylinder of described compact type scribbles low-friction lubrication fat on described piston packing (6).Described piston packing (6) is special rubber.
Adopt honing processing in described inner wall of cylinder, degree of finish is less than 0.4 μ m.Thereby cylinder is active in one's movements, breakout pressure 0.005Mpa, and common cylinder is 0.05MPa.
The beneficial effects of the utility model:
The lifting of disc system and pressurization are finished by the cylinder of two series connection respectively on the utility model, and master cylinder is responsible for going up the fast lifting of disc system, and pressurized cylinder is responsible for going up the pressure control of disc system.When adopting traditional standard cylinder, master cylinder and adding between the air cylinder by the transition adpting flange connects, and has increased axial dimension virtually.In the utility model, will add the rear end cover thickening of air cylinder, and do and the consistent tapped hole of master cylinder cylinder bar rod end screw thread in the rear end cover neutral position, like this master cylinder can be directly with add air cylinder and link to each other, saved the middle transitional adpting flange.The cylinder bar front end outside thread of pressurized cylinder is made consistent with the screw thread of pulling force sensor, and pressurized cylinder can directly link to each other with pulling force sensor, can save the middle transitional part equally.Adopt above structure, effectively dwindled axial installation dimension, shortened the installation dimension of last disc system greatly.The welded structure of front end housing, back cylinder cover adopt sunk screw to connect, and head has strengthened the cylinder safety in utilization greatly on the one hand, and the cylinder outward appearance is neat on the other hand, smooth and beautiful appearance.Special piston seal not only can play the effective seal effect, has also realized the low frictional properties of motion, is to realize going up the accurately strong guarantee of control of disc system pressure.
The sensitive cylinder of the utility model compact type, the pressure control and slow liter that are mainly used in disc system on electronics special processing equipment twin polishing/lapping machine are slowly fallen usefulness, and also can be used for other needs accurate pressure control and low speed steadily to move the occasion of control.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
The structural representation of two cylinder series connection of Fig. 2 lifting and pressurization.
Among the figure: 1, cylinder back cover; 2, be connected with master cylinder and use tapped hole; 3 seal rings; 4, screw connecting hole; 5, piston; 6, seal ring; 7, cushion pad; 8, piston rod; 9, protecgulum; 10, the rod end screw thread that is connected with pull sensing; 11, seal ring; 12, ventilating hole; 13, cylinder barrel; 14 cushion pads; 15, ventilating hole; 16, master cylinder lever; 17, nut.
Embodiment:
Below principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
Embodiment 1: the sensitive cylinder of a kind of compact type, include cylinder back cover 1, cylinder protecgulum 9 is connected with cylinder barrel 13 respectively, and cylinder barrel 13 is provided with upper vent 15 piston rods 8 and is provided with piston 5, includes to be provided with on cylinder back cover 1 to be connected usefulness tapped hole 2 with master cylinder.The rod end of described piston rod 8 is provided with the rod end screw thread that is connected with pulling force sensor.Between described cylinder back cover 1 and piston 5, be provided with cushion pad 14; Between cylinder protecgulum 9 and piston 5, be provided with cushion pad 7 down.On described piston 5, be provided with piston packing 6.On described piston packing 6, scribble low-friction lubrication fat.Adopt welded structure between pressurized cylinder front end housing and cylinder barrel, back cylinder cover adopts sunk screw to be connected with cylinder barrel, do and the consistent tapped hole of master cylinder cylinder bar rod end screw thread in the back cylinder cover neutral position, the cylinder bar rod end screw thread of pressurized cylinder is divided into two sections, wherein the front end outside thread is consistent with the screw thread of pulling force sensor, and elastic buffer is adopted at cylinder stroke two ends, and piston adopts the integrated type low friction type, guaranteeing to realize the low frictional properties of motion under the reliable sealing prerequisite.Two ventilating holes are left in the cylinder side, add low-friction lubrication fat in the cylinder.
Embodiment 2: as Fig. 2, the sensitive cylinder of described compact type is connected with master cylinder by being connected with tapped hole 2 with master cylinder.
Go up when this cylinder is used for twin polishing/lapping machine work that the slow liter of dish is slow to fall and tonnage is accurately controlled, master cylinder lever (or other actuating mechanisms) screws in its bonnet tapped hole can carry out the fast liter of big stroke and fall action soon.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
