Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, the controlled clamping mechanism of fluid pressure type of the present utility model comprises fixed support plate 1, the left part of fixed support plate 1 is fixedly connected with hydraulic actuating cylinder, the piston 4 that hydraulic actuating cylinder comprises horizontal cylinder body 2 and is located in the cavity 3 of cylinder body 2, cylinder body about 2 both ends are respectively equipped with the hydraulic oil being communicated with cylinder body 2 cavity and import and export 5, and piston 4 stroke is imported and exported between 5 at the described hydraulic oil in two, left and right; Piston 4 is connected with piston rod 6, and piston rod 6 stretches out cylinder body 2 to the right and coordinates with cylinder body 2 slipper seal.
Piston rod 6 is connected with guide rails fixing support 7 to the right, and guide rails fixing support 7 is in isosceles trapezoid and its shorter upper base is positioned at the longer right side of going to the bottom; The Liang Yaochu of guide rails fixing support 7 is connected to guide rail 8, and each guide rail 8 slidably connects guide rail slide block 9 respectively;
The right part of fixed support plate 1 is symmetrically fixed with two hinge pin 10 up and down, and the hinge pin 10 on top is hinged with grip block 11, and the hinge pin 10 of bottom is hinged with lower grip block 12, and upper and lower grip block 11,12 forms retaining paw; The left part lower edge of upper grip block 11 is obliquely installed and is fixedly connected with the guide rail slide block 9 at the upper waist place of guide rail slide block 9(guide rails fixing support 7), the left part upper edge of lower grip block 12 is obliquely installed and is fixedly connected with the guide rail slide block 9 at the lower waist place of guide rail slide block 9(guide rails fixing support 7); The right part of upper grip block 11 bends downwards and is provided with upper clipping claw 13, and the right part of lower grip block 12 upwards bends and is provided with lower claw 14, and upper and lower claw 13,14 correspondence is arranged.The bottom of upper clipping claw 13 and the top of lower claw 14 are respectively equipped with anti-slip veins, thus increase the friction force between upper and lower claw 13,14 and clamped article, make clamping process more stable.
As a kind of mode of bearing fit, described guide rail 8 comprises base plate 15, and in the middle part of base plate 15, projection is provided with sliding connection plate 16; Described guide rail slide block 9 offers chute 17, and described sliding connection plate 16 stretches into described chute 17.Certainly, guide rail 8 and guide rail slide block 9 can also adopt the form of common square rail and square rail slide block.
The two side of described chute 17 is respectively equipped with ball caulking groove 18, ball 19 is provided with in ball caulking groove 18, the opening of ball caulking groove 18 is less than the diameter of ball 19, thus ball 19 can not be come off from ball caulking groove 18, the part that ball 19 protrudes ball caulking groove 18 is rolled with described sliding connection plate 16 and is coordinated, thus reduces the friction force (becoming force of rolling friction from force of sliding friction) between guide rail slide block 9 and guide rail 8.
The fitting surface of described piston and cylinder body 2 is provided with seal groove 20, is embedded with seal ring 21 in seal groove 20; Described cylinder body 2 side is connected with gland 22 in piston rod 6 place, and the cylinder body at gland 22 and gland 22 place is provided with seal ring 21 around piston rod 6.The setting of seal ring 21, enhance the leak tightness of hydraulic actuating cylinder, working process is more stable.
During use, on the mount pad as required fixed support plate 1 in the utility model being arranged on conveyor line or other use occasions, usual mount pad can rotate or periodically move back and forth, to drive the utility model to move to extended position by clip position.
At clip position, primer fluid cylinder pressure, namely imports and exports 5 by the hydraulic oil of cylinder body 2 left part and pass into hydraulic oil in the cavity 3 of cylinder body 2, promotes piston 4, piston rod 6, guide rails fixing support 7 and guide rail 8 and moves right.Because guide rail 8 is arranged on two waists of guide rails fixing support 7, therefore grip block 11 can upwards be propped up gradually when guide rail 8 moves right, make grip block 11 around hinge pin 10 clickwise, same grip block 12 is at present pushed makes left-hand revolution, thus time upper clipping claw 13 and lower claw 14 close to each other, by workpiece or material clamping get up.Then the mount pad on conveyor line drives the utility model to rotate to or is linearly moved to extended position, now reverse operating is carried out to hydraulic actuating cylinder, namely import and export 5 by the hydraulic oil of cylinder body 2 right part and pass into hydraulic oil in cylinder body 2, promote piston 4, piston rod 6, guide rails fixing support 7 and guide rail 8 to be moved to the left, upper and lower grip block 11,12 all loses thrust to the right, make upper clipping claw 13 and lower claw 14 lose Clamping force, material falls at extended position automatically.
In a word, the utility model structure is simple, is convenient to manufacture and use, and cost is lower, and functional reliability is strong, and by promoting, upper grip block 11 is relative with lower grip block 12 to be rotated, and upper clipping claw 13 and lower claw 14 can be made stably to clamp material.Regulate the pressure by hydraulic oil in hydraulic actuating cylinder, the size of Clamping force can be regulated, enable the utility model be applicable to the multiple occasion needing holding articles.
Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although be described in detail the utility model with reference to above-described embodiment, those of ordinary skill in the art is to be understood that: still can modify to the utility model or equivalent replacement, and not departing from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of right of the present utility model.
