Description
Technical Field
The utility model relates to an anchor clamps field, especially a long stroke clamping mechanism of rotation type.
Background
The existing clamp generally adopts a hinge oil cylinder or a corner oil cylinder, when the material is loaded, a clamping jaw is fully opened, and a loading space above a clamping station is kept away, so that the operator can conveniently load the material. In addition, if the distance between the clamping point and the oil cylinder is far, the traditional method of lengthening the length of the pressing claw of the oil cylinder is adopted, the feeding side is arranged compactly, the arrangement cannot be carried out under extreme conditions or at all, the feeding distance can be increased, the operation is inconvenient, and the workload is increased. Meanwhile, workpieces easily collide with the clamping jaw in the feeding and discharging processes, and damage is caused. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
Disclosure of Invention
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed, can make full use of anchor clamps rear side with control the unnecessary space of side, reduce the rotation type long stroke clamping mechanism that material loading side space used.
The technical solution of the utility model is that: the utility model provides a rotation type long stroke clamping mechanism which characterized in that: the clamping mechanism comprises a support 1, a bearing seat 2 is connected above the support 1, a rotating shaft 3 is rotatably connected in the bearing seat 2, a gear 4 is connected to the bottom key of the rotating shaft 3, a rack 5 meshed with the gear 4 is movably connected in the bearing seat 2, the rack 5 is connected with the working end of a driving oil cylinder, the top end of the rotating shaft 3 is connected with a pressing plate 7 through a connecting pin shaft 6, an oil cylinder 8 is arranged at one end of the pressing plate 7, a pressing head 9 is arranged at the end part of the working shaft of the oil cylinder 8,
the bearing seat 2 is further connected with a support 10, the support 10 is connected with a first screw 11 in a threaded mode, the bottom end face of the pressing plate 7 is connected with a second screw 12 in a threaded mode, the second screw 12 is connected with a compression nut 13 in a threaded mode, meanwhile, the second screw 12 and the oil cylinder 8 are respectively located at two ends of the pressing plate 7, and when the oil cylinder 8 is located at a clamping station, the second screw 12 is located right above the first screw 11.
Compared with the prior art, the utility model, have following advantage:
the rotary long-stroke clamping mechanism with the structure is simple in structure, ingenious in design and reasonable in layout, and aims at the problems existing in the use process of a traditional clamp, a swing type action clamp structure is designed, the oil cylinder and the pressure head are driven to move through the swing action of the pressure plate, the oil cylinder and the pressure plate completely leave the upper part of a clamping station in a non-compression state, the feeding is facilitated for operators, the swing type movement mode movement amplitude is relatively small, and too large movement space does not need to be occupied. Meanwhile, the manufacturing process is simple, the manufacturing cost is low, so that the novel LED lamp has various advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1: the utility model provides a rotation type long stroke clamping mechanism which characterized in that: the clamping mechanism comprises a support 1, a bearing seat 2 is connected above the support 1, a rotating shaft 3 is rotatably connected in the bearing seat 2, a gear 4 is connected to the bottom key of the rotating shaft 3, a rack 5 meshed with the gear 4 is movably connected in the bearing seat 2, the rack 5 is connected with the working end of a driving oil cylinder, the top end of the rotating shaft 3 is connected with a pressing plate 7 through a connecting pin shaft 6, an oil cylinder 8 is arranged at one end of the pressing plate 7, a pressing head 9 is arranged at the end part of the working shaft of the oil cylinder 8,
the bearing seat 2 is further connected with a support 10, the support 10 is connected with a first screw 11 in a threaded mode, the bottom end face of the pressing plate 7 is connected with a second screw 12 in a threaded mode, the second screw 12 is connected with a compression nut 13 in a threaded mode, meanwhile, the second screw 12 and the oil cylinder 8 are respectively located at two ends of the pressing plate 7, and when the oil cylinder 8 is located at a clamping station, the second screw 12 is located right above the first screw 11.
The utility model discloses long stroke clamping mechanism of rotation type's working process as follows: in the initial state, the oil cylinder 8 is in a non-clamping state, and no barrier exists above the clamping station, so that an operator can conveniently feed materials;
after the feeding operation is finished and when a workpiece needs to be clamped, a driving oil cylinder is started, the driving oil cylinder drives a rack 5 to do linear motion along the axis of the driving oil cylinder, a gear 4 meshed with the rack is driven to rotate, a rotating shaft 3 in key connection with the gear 4 can drive a pressing plate 7 to swing, the oil cylinder 8 moves to the position above the workpiece, then the oil cylinder 8 works, and a pressing head 9 presses the workpiece tightly;
in consideration of convenience and space saving, the distance between the oil cylinder 8 and the rotating shaft 3 is certainly relatively long (namely, the force arm of the oil cylinder 8 is relatively long), so that the pressing plate 7 can bear large overturning moment, once the pressing head 9 is contacted with a workpiece, one end of the pressing plate 7, which is far away from the pressing head 9, tends to swing downwards, so that a first screw 11 and a second screw 12 which are matched with each other are arranged at the section of the pressing plate 7, when the pressing head 9 is positioned at a pressing station, the second screw 12 is just positioned right above the first screw 11, and the two screws can be ensured to be contacted with each other when the mechanism is in a clamping state by adjusting the relative position of the second screw 12 and the pressing plate 7 (after the adjustment is finished, the pressing nut 13 is used for fixing the two screws).
