Abstract

The utility model discloses a driving cylinder of which a piston rod capable of conducting combination movement of linear and rotation, which comprises cylinder body, an end cover (8), a piston (7) and a piston rod (1). A sliding tube (2) is fixedly connected with a cylinder body (6) in the coaxial line; the sliding tube (2) and the piston rod (1) are in clearance fit; the piston rod can always stretch out of the sliding tube; a curve guide groove (4) is arranged on the part of the piston rod (1) stretching out of the cylinder body (6) and located in the sliding tube (2); a pin column hole (9) is arranged at the upper edge of the sliding tube along the radial direction; a guide pin (10) is inserted into the pin column hole to be placed in the curve guide groove (4) and can relatively slide along the curve guide groove; when the piston is in reciprocating motion, the guide pin has a movement guide role for the curve guide groove on the piston rod; when the spiral section or the arc section of the curve guide groove passes through the guide pin, the piston rod can generate spiral movement during linear motion.

Description

Piston rod can be done the drive cylinder of straight line and rotation combination motion
Affiliated technical field
The utility model relates to a kind of drive cylinder, and particularly its piston rod can be done the oil hydraulic cylinder or the cylinder of straight line and rotation combination motion.
Background technique
Drive cylinder comprises oil hydraulic cylinder and cylinder, and it can change hydraulic pressure energy or air pressure into mechanical energy, is very common executive component, is used for realizing the motion of linear reciprocation.And some special occasions require piston rod both to do straight line motion, do the rotation of certain rule again, need to realize the aggregate motion of straight line and rotation.Therefore, designing a kind of piston rod, can to do the drive cylinder of straight line and rotation combination motion very necessary.
The model utility content
The purpose of this utility model is in order to provide a kind of piston rod can do the drive cylinder of straight line and rotation combination motion, in the piston rod straight reciprocating motion process, can to rotate according to certain rules automatically, thereby can realize the aggregate motion of straight line and rotation.
The technological scheme that its technical problem that solves the utility model adopts is:
The utility model comprises cylinder body, end cap, piston and piston rod, slide cartridge and cylinder body coaxial line connect firmly, slide cartridge and piston rod Spielpassung, the extended all the time slide cartridge of piston rod, stretch out cylinder body and be on the part in the slide cartridge at piston rod and be provided with the curve orientation groove, radially be provided with pin hole on the slide cartridge wall, guide finger inserts that pin hole is placed in the curve orientation groove and can be along curve orientation groove slide relative, curve orientation groove total length vertically is greater than the stroke of piston, and when piston was in the two ends limit position, the curve orientation groove end on the piston rod did not contact with guide finger.
Adopt such scheme, when reciprocating motion of the pistons, the guide finger that is installed on the slide cartridge has the motion guide effect to the curve orientation groove on the piston rod.When the spiral section of curve orientation groove or arcuate segment during by guide finger, piston rod rotates motion simultaneously straight-line; When the axial straightway of curve orientation groove passes through guide finger, a piston rod moving linearly.
Adopt above-mentioned scheme, can reach following beneficial effect:
1, under the effect of curve orientation groove on the piston rod and the guide finger on the slide cartridge, piston rod can be done the aggregate motion of straight line and rotation.
2, can realize exporting the straight line of different motion rule and the aggregate motion of rotation by designing different curve orientation grooves.
Description of drawings
Fig. 1 is the utility model one embodiment's a structural drawing;
Fig. 2 is a piston rod embodiment illustrated in fig. 1 structural drawing when regaining.
Among the figure: 1, piston rod 2, slide cartridge 3, dust ring 4, curve orientation groove 5, screw 6, cylinder body 7, piston 8, end cap 9, pin hole 10, guide finger 11, pin 12, roller
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model embodiment one a structural drawing, comprise cylinder body 6, end cap 8, piston 7 and piston rod 1, slide cartridge 2 adopts screw 5 to connect firmly with cylinder body 6 coaxial lines, slide cartridge 2 and piston rod 1 Spielpassung, the extended all the time slide cartridge 2 of piston rod 1, stretch out cylinder body 6 and be on the part in the slide cartridge 2 at piston rod 1 and be provided with curve orientation groove 4, radially be provided with pin hole 9 on the slide cartridge wall, guide finger 10 inserts that pin hole 9 are placed in the curve orientation groove 4 and can be along curve orientation groove 4 slide relative, curve orientation groove 4 total length S2 vertically is greater than the range S1 of piston rod 1, and when piston was in the two ends limit position, curve orientation groove 4 terminations on the piston rod 1 did not contact with guide finger 10.
Adopt such scheme and structure, when piston linear moved, the curve orientation groove 4 that is installed on the 10 pairs of piston rods 1 of guide finger on the slide cartridge 2 had the motion guide effect.When the spiral section of curve orientation groove 4 or arcuate segment during by guide finger 10, piston rod 1 rotates motion simultaneously straight-line; When the axial straightway of curve orientation groove 4 passes through guide finger 10,1 moving linearly of piston rod, the structural drawing when Fig. 2 regains for piston rod.Under the effect of curve orientation groove 4 on the piston rod 1 and the guide finger 10 on the slide cartridge 2, piston rod 1 can be done the aggregate motion of straight line and rotation.Can also realize exporting the straight line of different motion rule and the aggregate motion of rotation by designing different curve orientation grooves.Because of the stroke S1 of curve orientation groove 4 total length S2 vertically greater than piston rod 1, and piston 7 is when being in the two ends limit position, and the curve orientation groove end 4 on the piston rod 1 does not contact with guide finger 10.Can not be subjected to the axial restraint of guide finger 10 when having guaranteed piston rod 1 to-and-fro motion like this.
Among Fig. 1,2, slide cartridge 2 one ends adopt screw 5 to connect with cylinder body 6, and slide cartridge 2 middle part internal diameters are greater than piston rod 1 diameter, and the other end is a guide section, and with piston rod 1 Spielpassung, its guide section is provided with dustproof ring recess, and dust ring 3 has been installed.Like this, slide cartridge inside has formed the space of a sealing, prevents entering of external dust effectively.Guide finger 10 is made of pin 11 and the roller 12 that is enclosed within on the pin 11, and during assembling in guiding slide cartridge 2 especially curved slot 4 scribble lubricating grease with guide finger 10 places.Like this, can reduce running resistance effectively.
Utilize the technical solution of the utility model can design oil hydraulic cylinder and cylinder.
