Abstract
The utility model relates to a single-finger small-diameter cylinder sleeve grabbing mechanism. The single-finger small-diameter cylinder sleeve grabbing mechanism comprises a cylinder body and is characterized in that the cylinder body is internally radially provided with a driving cylinder, a piston of the cylinder and a plunger piston are connected into a whole, and the plunger piston can do radial movement in certain range when the plunger piston is driven by the piston; a compression spring used for resetting the plunger piston and a spring cover cap used for fixing the compression spring are arranged outside the plunger piston, and the plunger piston is located in a retraction position under the action of an elastic force of the compression spring; an air inlet/outlet communicated with the piston is formed in the cylinder body; and when compressed gas is introduced from an air inlet, the piston drives the plunger piston to overcome the elastic force of the compression spring and radially eject, so as to apply an outward radial force to the inner wall of a cylinder sleeve. The single-finger small-diameter cylinder sleeve grabbing mechanism firstly can be used for grabbing a small-diameter cylinder sleeve from inner diameter, can be used for guiding and positioning, and also can avoid interference between claws of a manipulator and a metal mould.
Description
Technical field
The one hand that the utility model relates to a kind of corresponding minor diameter cylinder sleeve refers to grasping mechanism, belongs to robot mechanical arm pawl technical field.
Background technology
In motorcycle engine cylinder body die casting production process, when in metal die, inlaying cylinder sleeve, adopt special fixture or robot hand usually, the clamping cylinder sleeve is bumped in the metal die.Generally the manipulator from inner radius extracting cylinder sleeve has three or four groups of fingers.Because the diameter of cylinder is less, so the diameter of cylinder sleeve is also less, adopt many finger claws to the minor diameter cylinder sleeve when inner radius grasps, the space layout design of claw is comparatively difficult.
And employing promptly in the method for outer radius clamping, can make and produce mechanical interference between mechanical paw and the metal die, and can damage and make the liner backs after the surface treatment from the external cylindrical surface of cylinder sleeve.
Summary of the invention
The technical problems to be solved in the utility model is to realize the minor diameter cylinder sleeve is grasped from inner radius, and guiding and location.
In order to solve the problems of the technologies described above, technical scheme of the present invention has provided a kind of minor diameter cylinder sleeve one hand and has referred to grasping mechanism, comprise cylinder body, it is characterized in that: the driving cylinder radially is installed in cylinder body, the piston and the plunger of cylinder are connected as a single entity, plunger can move radially in certain scope under the driving of piston.The compression spring that plunger return is used is housed in the outside of plunger, and the spring cover cap of fixing compression spring position, plunger is in the position of withdrawal under the resilient force of compression spring.On cylinder body, have the air inlet/outlet that is connected with piston.When the logical Compressed Gas of air inlet, piston drives the elastic force that plunger overcomes the compression spring and radially ejects, and the inwall of cylinder sleeve is applied outside radial load.
Preferably, described plunger moves radially in the scope less than 5mm.
Preferably, be provided with the guide-localization cover in the outside of described cylinder body, this guide-localization cover applies outside radial load to the inwall of cylinder sleeve jointly with the plunger that radially ejects, the mode fixed clamp cylinder sleeve that rises with inner support.
Preferably, the leading section that overlaps at described guide-localization is provided with taper seat, and the cylinder sleeve of being inlayed is enclosed within outside the guide-localization cover.When inlaying cylinder sleeve under the cooperation of manipulator floating installation the taper seat of guide-localization cover leading section play the guide-localization effect.
The utility model at first can be realized the minor diameter cylinder sleeve is grasped from inner radius, and can lead and locate, and secondly, can avoid the interference between mechanical paw and the metal die.
Description of drawings
A kind of minor diameter cylinder sleeve one hand that Fig. 1 provides for the utility model refers to the structural representation of grasping mechanism.
The specific embodiment
For the utility model is become apparent, now with preferred embodiment, and conjunction with figs. is described in detail below.
As shown in Figure 1, the utility model provides a kind of minor diameter cylinder sleeve one hand to refer to grasping mechanism, be included in one hand and refer to radially be equipped with in the grasping mechanism cylinder body 4 that drives cylinder, the piston 9 and the plunger 1 of cylinder are connected as a single entity, plunger 1 can move radially in certain scope under the driving of piston 9.The reset compression spring 3 of usefulness of plunger 1 is housed in the outside of plunger 1, and the spring cover cap 2 of fixing compression spring 3 positions, plunger 1 is in the position of withdrawal under the resilient force of compression spring 3.On cylinder body 4, have the air inlet/outlet 5 that is connected with piston 9.
When the logical Compressed Gas of air inlet/outlet 5, piston 9 promotes the elastic force that plungers 1 overcome compression spring 3 and radially ejects, and the inwall of cylinder sleeve 6 is applied outside radial load.Guide-localization cover 7 is housed in the outside of cylinder body 4, and under the effect of the reaction force of plunger 1 radial load that applies, guide-localization cover 7 applies opposite radial load to cylinder sleeve 6 opposite side inner cylinder faces.Thereby, be implemented in the purpose of inner radius clamping cylinder sleeve with the mode fixed clamp cylinder sleeve that inner support rises.
When air inlet/outlet 5 led to atmosphere, plunger 1 inwardly moving radially withdrawal and resetting under the resilient force of compression spring 3, removes the clamping to cylinder sleeve 6.
In the utility model,,, grasp the cylinder sleeve of different inner diameters in certain scope so this mechanical paw can adapt to automatically because plunger 1 can move radially.
Leading section at guide-localization cover 7 is provided with taper seat 8, and the cylinder sleeve of being inlayed 6 is enclosed within outside the guide-localization cover 7.Under the cooperation of manipulator floating installation (not drawing among the figure), the taper seat 8 that guide-localization overlaps 7 leading sections can play the guide-localization effect when inlaying cylinder sleeve.
