Detailed Description
The following detailed description will be further described in conjunction with the above-identified drawings.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the concepts underlying the described embodiments. It will be apparent, however, to one skilled in the art, that the described embodiments may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail.
Referring to fig. 1 to 2, the telescopic clamping mechanism includes a mounting base 1, wherein two ends of the mounting base 1 are provided with mounting portions 2 extending downward, and two ends of a connecting shaft 3 are respectively connected with the two mounting portions 2; the connecting shaft 3 is rotatably sleeved with two clamping jaws 4, and the two clamping jaws 4 are arranged oppositely; the mounting base 1 is further provided with a telescopic mechanism 5, a connecting plate 6 is arranged at the telescopic end of the telescopic mechanism 5, and a connecting rod 7 is connected between the connecting plate 5 and the corresponding clamping jaw 4; the telescopic mechanism 5 is telescopic, and the connecting rod 7 pushes the two clamping jaws 4 to open and clamp. When the telescopic clamping mechanism clamps an object, the telescopic mechanism 5 is telescopic, and the connecting rod 7 pushes the two clamping jaws 4 to swing oppositely, so that the object is clamped; however, during clamping, the connecting rod 7 generates a pulling force or a pushing force, so that the moment of the clamping jaws 4 is increased, and according to the principle of leverage, the clamping force of the two clamping jaws 4 is greater than the pushing force or the pulling force of the connecting rod 7, that is, the clamping force of the two clamping jaws 4 is greater than the driving force of the telescopic mechanism 5; therefore, under the same driving force, the clamping force of the clamping mechanism of the telescopic clamping mechanism is larger than that of a traditional parallel clamp and a pneumatic clamping jaw. That is, under the condition of the same clamping force, the driving force required by the telescopic clamping mechanism is smaller than that of the traditional machine, and the maximum output force of the telescopic mechanism 5 is also lower than that of the traditional clamping mechanism; therefore, when the clamping mechanism is applied to a manipulator or automatic equipment, the cost of the clamping mechanism can be reduced, and the running cost of the clamping mechanism can be reduced.
Furthermore, the upper ends of the two clamping jaws 4 are provided with connecting portions 40 extending outwards, the free ends of the connecting portions 40 are pivoted with the corresponding connecting rods 7, and the upper ends of the connecting rods 7 are pivoted with the connecting plates. In this embodiment, the connecting portion 40 can be pivoted with the connecting rod 7, and can increase the moment of the clamping jaw 4; thereby realizing the increase of the clamping force when the two clamping jaws 4 clamp.
Further, when the telescopic mechanism 5 pushes the two clamping jaws 4 to clamp, the two connecting rods 7 are parallel to the axis of the telescopic shaft of the telescopic mechanism 5 and perpendicular to the corresponding connecting portion 40. In this embodiment, since the connecting rod 7 is perpendicular to the connecting portion 40 when the two clamping jaws 4 clamp each other, and the moment of the clamping jaw 4 is the largest when the connecting rod is perpendicular to the connecting portion 40, when the clamping jaw 4 clamps an object, the clamping force is the largest, so that the object can be clamped more stably.
Further, when the telescopic mechanism 5 extends upwards, the two clamping jaws 4 are clamped with each other. In this embodiment, the connecting portion 40 of the clamping jaw 4 extends in the direction of the other clamping jaw 4; the joint of the connecting part 40 and the clamping jaw 4 is connected with the connecting shaft 3, so that the connecting strength of the clamping jaw 4 and the connecting shaft 3 is increased.
Furthermore, a clamping block 41 extending downwards is arranged on the inner side of the clamping jaw 4; a clamping portion 42 extends from the lower end of the inner side of the clamping block 41. In this embodiment, the clamping portion 42 is disposed at the lower end of the clamping block 41, so that when the two clamping blocks 41 are clamped, the clamping portion 42 of the two clamping blocks 41 is in contact with the object, and the upper end of the clamping block 41 is the upper end of the object capable of avoiding space; therefore, the contact area of the clamping block 41 and the object is reduced, the interference area of the object and the clamping block 41 is reduced, and the clamping is stable. And different clamping blocks 41 can be replaced according to requirements, so that clamping of different objects can be met.
Further, the telescopic mechanism 5 is any one of a telescopic cylinder, a hydraulic rod or an electric rod.
The present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes without creative labor from the above conception, and all the changes fall within the protection scope of the present invention.
