Abstract
Braking device for cylinder piston rod can correctly provides fixing force, including: a plurality of floor heave; brake cylinders; brake.
Description
Technical field
The utility model relates to the brake equipment of the cylinder piston rod of logistics transfer system, the piston rod of the cylinder by being used for fixing load in the logistics transfer system is load fixedly, simultaneously at the stationkeeping piston rod that fulfils assignment, thereby can provide certain bed knife for load.
Background technology
The logistics transfer system as less article or bigger and heavy article are sent to position of carrying out next process or the electromechanical integrated device that constitutes finishing product to pack, have widely at whole industrial circle and uses in process of production.
The brake equipment of this logistics transfer system is most of for being applicable to oil gas pressing systems such as cylinder or oil hydraulic cylinder, transmission for small article can be used the vacuum suction mode, and large piece article can be fixed in the fixing clamp area from a plurality of directions coordination application of forces in piston rod end that a plurality of cylinders are set and transmit.
As having, can enumerate the semi-finished transfer system of motor tire from the system example of the clamp area of a plurality of direction work.
Fig. 1 has provided the part-structure of this motor tire transfer system.
With reference to accompanying drawing, around adding sulphur tire 1, be not provided with annular brace platform 2, fixed a plurality of cylinders 4 that have clamp area 3 in the piston rod end along the center position of 2 of brace tables.
This device has shown and has taken out from make-up machine by eduction gear after moulding on the make-up machine, is sent to the part process of the position that adds the sulphur engineering then by conveyer.
Said apparatus starts simultaneously by each cylinder 4, controls from the clamp area 3 of all directions while application of force not add sulphur tire 1.
The problem that cylinder exists is because gas compression produces volume change, thereby is influencing lower piston rod generation relaxation phenomenon as the air pressure of driving pressure.Because this phenomenon can reduce the efficient of fixed object,, all to avoid the piston rod relaxation phenomenon for the various article transfer machines of the use pressure system transmission that comprises the tire transfer system than heavy articles.
As solving the relax countermeasure of the problem that causes of cylinder piston rod, use the screw shaft of the roll mode that the propulsive effort by motor is rotated for the tire transfer system.
This screw shaft is compared the piston rod that straight line come and go to move, little many of its axial deformation, but can't export along the slip of screw rod tangential direction, and price is also very high.
The utility model content
The purpose of this utility model provides a kind of brake equipment of cylinder piston rod, and this brake equipment can accurately provide bed knife.
The purpose of this utility model is realized by following technical scheme: a kind of brake equipment of cylinder piston rod comprises: on the outside face of the guide shaft that guiding master cylinder piston bar moves, along a plurality of stratiform projectioies of the direction formation that intersects with axle; Brake cylinder, the direction configuration that the piston rod of this brake cylinder intersects along the axle with guide shaft; And be fixed on drg on the brake cylinder piston rod, be formed with the projection that has correspondingly-shaped with the projection of guide shaft on this drg.
The beneficial effects of the utility model are, finish the operation of regulation at the piston rod of cylinder after, the state that will carry out operation keeps certain hour in dead position, can realize cylinder operation more accurately.

The specific embodiment
For achieving the above object, technical characterstic of the present utility model is that its composition comprises: on the outside face of the guide shaft that guiding master cylinder piston bar moves, along a plurality of stratiform projectioies of the direction formation that intersects with axle; After the master cylinder piston bar fulfils assignment, by the brake cylinder that electric signal starts, the direction back and forth movement that the piston rod of this brake cylinder intersects along the axle with guide shaft; And be fixed in drg on the brake cylinder piston rod, be formed with the projection that has correspondingly-shaped with the projection of guide shaft on this drg.
With reference to accompanying drawing, describe as follows to the utility model embodiment.
Fig. 2 to Fig. 6 is the scheme drawing relevant with the utility model embodiment.
The air cylinder device of the logistics transfer system that the utility model is suitable for, in upper body 10 upper fixed master cylinder 20 is arranged, piston rod 21 ends at master cylinder 20 are fixed with fixer 30, this fixer 30 is provided with the clamp area (not diagram) that is used to control load, is fixed with a pair of guide shaft 40, the 40a that are slidably disposed in the upper body 10 on the fixer 30.
Specify for, the central authorities of upper body 10 are formed with the through hole 11 that is used to insert master cylinder 20 piston rods 21, both sides are formed with axis hole 13, the 13a that is used to insert steel (for flint) 12,12a, lower central is formed with forms fixed block 14 of the present utility model.
Be formed with a plurality of stratiform projectioies 42,42a respectively at the horizontal surface 41 of guide shaft 40,40a outside face inboard, certain position on the 41a, when being fixed in when fixing 30 projection 42,42a relative fixed.
Fixed block 14 is integrally formed in the lower central of upper body 10, is through with the through hole 11 that is used to insert piston rod 21, and both sides are provided with towards guide shaft 40,40a by screw retention brake cylinder 50,50a.
Be fixed with tetragonal fixed block 51,51a on the piston rod of brake cylinder 50,50a, fixed block 51,51a is last is fixed with drg 60,60a by check screw 70,70a.
The utility model is provided with lower body 80, and the brake cylinder 50, the 50a that guarantee to be fixed in upper body 10 can trouble free services.
Be formed with on the lower body 80 and be used to accommodate the brake cylinder 50 with drg 60,60a, the space 81 of 50a, be formed with axis hole 82, the 82a that is used to insert guide shaft 40,40a in the both sides in above-mentioned space 81, and this lower body 80 can be passed through screw retention upper body 10.
Above-mentioned space 81 and axis hole 82,82a form same space.Therefore upper body 10 and lower body 80 in conjunction with the time, the projection 61 of drg 60,60a, 61a are separated by with projection 42, the 42a of guide shaft 40,40a respectively, and suitable distance is relative to be disposed.
Aforesaid the utility model, after master cylinder 10 starts, when sensing piston rod 21 and finishing the operation of regulation, for example, by can induction piston bar 21 or the sensor (not diagram) of the maximum position that advances of guide shaft 40,40a, produce the electric signal that drives brake cylinder 50,50a, drg 60,60a are advanced, projection 42, the 42a that projection 61,61a and the guide shaft 40 that drg 60,60a form, 40a form is inserted into each other in groove and mesh, thereby fixedly guide shaft 40,40a make it and can't move.
Therefore, pressure will take place master cylinder 20 changes, even the power effect of slight mobile piston bar 21 is arranged, guide shaft 40,40a also can keep static position.
A kind of embodiment that above-mentioned embodiment is just specialized the utility model technological thought, the utility model are not limited to the item of above-mentioned embodiment and accompanying drawing record.The people who has background context knowledge in field described in the utility model can derive other numerous embodiments based on above-mentioned embodiment fully.
For example, though be to form projection 42,42a on guide shaft 40,40a in the above-mentioned embodiment, also can form projection in the side or the both sides of piston rod 21, be oppositely arranged drg, certainly, this change embodiment still belongs to the utility model technical scope.
Aforesaid the utility model, finish the operation of regulation at the piston rod of cylinder after, the state that will carry out operation keeps certain hour in dead position, can realize cylinder operation more accurately.
