Abstract
The invention discloses an auxiliary bearing mechanism for holding closely. The auxiliary bearing mechanism comprises a symmetric structure body in which two guide rods with guide sleeves are symmetrically arranged in a vertical direction, the upper ends of the guide rods are connected with bearing blocks, and clamping sleeves are arranged below the guide sleeves and are connected with hydraulic oil pipelines; an oil cylinder with a piston rod is further arranged in the body in a horizontal direction, the piston rod is connected with a pull rod through a joint, and the pull rod is rotationally connected with the two guide rods; circular wedge blocks with springs are arranged on a connections between the pull rod and the two guide rods, and the two ends of the pull rod in the circular blocks are respectively provided with a retainer ring and a nut. According to the auxiliary bearing mechanism for holding closely provided by the invention, two auxiliary bearing points are driven to bear a work-piece and the guide rods are held closely through hydraulic oil by a clamping sleeve so as to ensure that a bearing point does not have any action when an engine cylinder, a cylinder cover and other critical parts are finely processed, therefore the processing precision can be ensured.
Description
Technical field
The present invention relates to a kind of supporting device, particularly relate to one and hold assistant supporting mechanism tightly for the vital part such as engine cylinder-body, cylinder cap is accurately machined.
Background technology
The vital part such as engine cylinder-body, cylinder cap when fine finishining, when location backup block from machining area away from or system rigidity not enough, at this moment often need increase aiding support block to strengthen system rigidity.Sometimes some machining area space requirement many places aiding support point guarantee system rigidity, if often place supporting all add actuating unit just seem loaded down with trivial details, waste.On the other hand, for ensureing in finishing passes, rest pad has not allowed loosening, bow tie generation.There is loaded down with trivial details, the huge shortcoming of structure in traditional aiding support.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, provide one to hold assistant supporting mechanism tightly, structure is simple, and can ensure machining accuracy.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
One holds assistant supporting mechanism tightly, comprise the body of symmetrical structure, two guide rods of band guide pin bushing are vertically arranged with in described body, described guide rod upper end is connected with rest pad, gripping sleeve is provided with below described guide pin bushing, described gripping sleeve is connected with hydraulic oil pipeline, the oil cylinder of band piston rod is also provided with in the horizontal direction in described body, described piston rod is connected with pull bar by joint, described pull bar and described two guide rods are rotationally connected, and junction is provided with the round voussoir of band spring, the two ends that described pull bar is positioned at round voussoir are respectively equipped with back-up ring and nut.
Further, be also provided with the stop pin running through guide pin bushing in described body, correspondingly described guide rod is provided with the keyway be mated.
Further, be provided with oblique dovetail key in described round voussoir, correspondingly the place of being rotationally connected is provided with dovetail key to described pull bar with it.
The invention has the beneficial effects as follows:
The present invention utilizes an actuator cylinder to drive two aiding support dot point workpiece, and gripping sleeve utilizes hydraulic oil to hold guide rod tightly, does not have any action, ensure that machining accuracy for supporting-point during the fine finishining of the vital part such as engine cylinder-body, cylinder cap.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, and form a application's part, schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of embodiment of the present invention;
Number in the figure illustrates: 1-body, 2-guide rod, 3-guide pin bushing, 4-rest pad, 5-gripping sleeve, 6-hydraulic oil pipeline, 7-oil cylinder, 8-piston rod, 9-joint, 10-pull bar, 11-circle voussoir, 12-spring, 13-back-up ring, 14-nut, 15-stop pin, 16-keyway, 17-workpiece.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
As shown in Figure 1, one holds assistant supporting mechanism tightly, comprise the body 1 of symmetrical structure, two guide rods 2 of band guide pin bushing 3 are vertically arranged with in described body 1, described guide rod 2 upper end is connected with rest pad 4, gripping sleeve 5 is provided with below described guide pin bushing 3, described gripping sleeve 5 is connected with hydraulic oil pipeline 6, the oil cylinder 7 of band piston rod 8 is also provided with in the horizontal direction in described body 1, described piston rod 8 is connected with pull bar 10 by joint 9, described pull bar 10 is rotationally connected with described two guide rods 2, and junction is provided with the round voussoir 11 of band spring 12, the two ends that described pull bar 10 is positioned at round voussoir 11 are respectively equipped with back-up ring 13 and nut 14.
Further, be also provided with the stop pin 15 running through guide pin bushing 3 in described body 7, correspondingly described guide rod 2 is provided with the keyway 16 be mated.
Further, be provided with oblique dovetail key in described round voussoir 11, correspondingly the place of being rotationally connected is provided with dovetail key to described pull bar 10 with it.
The operation principle of the present embodiment is:
Piston rod 8 on actuator cylinder 7 is by joint 9 pushing drawing rod 10, under the effect of spring 12 elastic force, promote two circle voussoirs 11 in body 1 pilot hole slides forwards, two circle voussoirs 11 on be processed with dove-tail form skewed slot promote two guide rods 2 in guide pin bushing 3 on move, rest pad 4 withstands workpiece 17, hydraulic oil pipeline 6 oil-feed that now gripping sleeve 5 is connected, gripping sleeve 5 holds guide rod 2 tightly, ensure that the stability of rest pad 4 in processing.Because rest pad 4 has directionality, stop pin 15 ensures that guide rod 2 can not rotate; Machine tooling is complete when unclamping, hydraulic oil pipeline 6 oil pressure that gripping sleeve 5 is connected is cancelled, and gripping sleeve 5 unclamps guide rod 2, and piston rod 8 moves after driving pull bar 10, after pull bar 10 front end nut 14 and back-up ring 13 promote two circle voussoirs 11, shipper pole moves guide rod 2 and moves down, thus drives rest pad 4 to move down to unclamp workpiece 17.
