Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical claws, and more specifically, to a bundled mechanical clamp. Background Art
[0002] The bundled mechanical clamp is a tool widely used in the industrial and related fields for clamping objects. By installing the bundled mechanical clamp on the control device and controlling the movement of the jaws on the mechanical clamp through the hydraulic cylinder, the object can be clamped and moved to the reserved position.
[0003] Currently, when controlling the bundled mechanical clamp to clamp an object, generally the upper or middle position of the object is clamped. To ensure stable clamping of the object and avoid dropping during the clamping process, the clamping force of the jaws on the object will increase, which may cause damage to the object due to excessive clamping force, resulting in the object being unusable. Moreover, during the clamping process, some objects are too heavy and are likely to fall under their own weight. Once they fall, they will hit the ground heavily, which is prone to danger. And during the falling process, they will rub against the inner wall of the jaws, causing the inner wall of the jaws to become smooth, affecting subsequent clamping and use of the object.

Detailed Embodiments
[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model. Embodiment
[0028] Refer to Figures 1 - 4, the present utility model provides a technical solution: a bundling mechanical clamp, which includes a connecting seat 1 and an auxiliary clamping mechanism 3, and a clamping jaw 2 is rotatably installed at the bottom of the connecting seat 1. The auxiliary clamping mechanism 3 includes an arc-shaped plate 31, the arc-shaped plate 31 is fixedly installed on the outer surface of the clamping jaw 2, and a clamping block 311 is fixedly installed at the inner bottom end of the arc-shaped plate 31. An attaching plate 32 is installed at the inner side of the arc-shaped plate 31. A vertical plate 321 is also fixedly installed on the inner side surface of the arc-shaped plate 31. A round rod 322 is rotatably connected inside the vertical plate 321. The round rod 322 is inserted into the attaching plate 32, and a convex block 323 is arranged on the outer side surface of the attaching plate 32 to increase the friction force when clamping an object. A hollow cylinder 33 is rotatably installed at the inner side of the arc-shaped plate 31, and a push rod 331 is arranged inside the hollow cylinder 33. One end of the push rod 331 is rotatably connected to the opposite surface of the attaching plate 32, and a spring 332 is installed inside the hollow cylinder 33 to control the position of the attaching plate 32.
[0029] In a preferred embodiment, a connecting block 4 is rotatably connected to the inner side of one end of the connecting seat 1. An installation hole 5 is opened at the upper end of the outer surface of the connecting block 4. The connecting block 4 is connected to an external device to control the rotation of the clamping jaw 2 to clamp an object. To facilitate controlling the clamping of the object by the clamping jaw 2, a connecting block 4 is installed on the connecting seat 1, and an installation hole 5 is arranged on the outer surface of the connecting block 4. During actual use, the external control device is connected to the connecting block 4, and by operating and controlling the rotation of the connecting block 4 through the external control device, the clamping jaw 2 can be driven to open or approach, so as to clamp and move the object.
[0030] In a preferred embodiment, a conical block 6 is fixedly installed at the bottom of the clamping jaw 2 for clamping an object and reducing the contact area with the object to increase the clamping force. Since the end area of the conical block 6 is narrow, the contact area between the conical block 6 and the object is small, and the pressure generated on the object will increase, thereby stably clamping the object.
[0031] In a preferred embodiment, one end of the spring 332 is fixedly installed at the inner bottom of the hollow cylinder 33, the other end of the spring 332 is fixedly connected to the push rod 331 arranged inside the hollow cylinder 33, and a torsion spring is arranged outside the round rod 322 to control the movement of the attaching plate 32. To improve the clamping effect on the object, a rotatable attaching plate 32 is arranged at the inner side of the arc-shaped plate 31, and a spring 332 is installed inside the hollow cylinder 33. By squeezing the push rod 331 through the spring 332, the attaching plate 32 can be stably attached to the outer surface of the object, so as to stably clamp the object.
[0032] In the process of clamping an object, since the object itself has a certain weight, it is easy to cause the object to fall if the clamping is unstable. To avoid such a situation, a supporting mechanism 7 is also installed on the arc plate 31. The supporting mechanism 7 includes a hydraulic cylinder 71, a support plate 72 and a connecting plate 73. The outer surface of the arc plate 31 is rotatably connected to the hydraulic cylinder 71, and the telescopic end of the hydraulic cylinder 71 is rotatably connected to the support plate 72. One end of the support plate 72 is set in a slope shape for moving to the bottom position of the object. The connecting plate 73 is rotatably installed at the bottom position of the outer arc surface of the arc plate 31, and a rectangular hole 8 is opened on the outer surface of the connecting plate 73. One end of the connecting plate 73 is rotatably connected to the outer side of the support plate 72, and a threaded column 9 is fixedly installed inside the upper end of the connecting seat 1. The outer portion of the threaded column 9 is sleeved with a limit plate 10, and a nut is threadedly connected to the threaded column 9 for squeezing and positioning the limit plate 10.
[0033] In actual use, at the beginning, one end of the support plate 72 is in a downward tilted state to avoid hindering the clamping of the object. When the object is clamped off the ground, the telescopic end of the hydraulic cylinder 71 pushes the support plate 72 to rotate, and the originally tilted support plate 72 is adjusted to a horizontal state, and the bottom of the object is lifted by one end of the support plate 72 to prevent the object from falling and falling, thereby meeting the requirements of use.
[0034] Specifically, the working process or working principle of a binding type mechanical clamp is as follows: when the binding type mechanical clamp is currently controlled to clamp an object, it is generally clamped at the upper or middle end of the object. In order to ensure stable clamping of the object and avoid falling during the clamping process, the clamping force of the clamp on the object will increase, which causes damage to the object due to excessive clamping force, thereby rendering the object unusable. In addition, during the clamping process, some objects are too heavy and are prone to fall under the action of their own weight. Once they fall, the objects will fall heavily to the ground, which is prone to danger. In addition, during the falling process, the objects will rub against the inner wall of the clamp, causing the inner wall of the clamp to rub smoothly, affecting the subsequent clamping and use of the object. Therefore, this device is designed to solve this problem.
[0035] The device can be used to clamp two positions on the outer surface of an object. By sharing the clamping force, it effectively replaces clamping at only one position, avoiding damage to the object caused by excessive clamping. At the same time, a protrusion 323 is installed on the attachment plate 32, and the protrusion 323 is in close contact with the outer surface of the object, thereby increasing the friction between the objects and avoiding the objects from falling and causing danger. The specific operation is as follows: the device is installed on the external control equipment, and is connected to the connecting block 4 through the hydraulic equipment on the external control equipment, and the limit plate 10 is installed on the external control equipment, so as to stabilize the use of the device.
[0036] When the object is clamped by this device, first control the movement of the connecting seat 1 through an external control device, and drive the clamping claws 2 to move directly above the object. Initially, the two clamping claws 2 are in an open state. When clamping the object, move the connecting seat 1 downward and sleeve the arc-shaped plate 31 at a position outside the object. At this time, one end of the supporting plate 72 touches the ground. By controlling the clamping claws 2 to move inward, the two clamping claws 2 are controlled to move relatively. While the clamping claws 2 rotate, they will drive the arc-shaped plate 31 to move. As the arc-shaped plate 31 continuously approaches the outer surface of the object, the attaching plate 32 will fit on the outer surface of the object, and the friction force with the object is increased through the convex blocks 323. As the clamping claws 2 continue to rotate, they will drive the arc-shaped plate 31 to rotate, causing the attaching plate 32 to clamp the object. At the same time, the arc-shaped plate 31 will also clamp the object. At this time, the clamping claws 2 will also clamp the object to stably clamp the object.
[0037] This device clamps the upper end of the object through the clamping claws 2 and clamps the bottom position of the object through the arc-shaped plate 31. By sharing the clamping force on the object, it can avoid damaging the object due to excessive clamping.
[0038] To improve the clamping stability of the object, a supporting mechanism 7 is also installed outside the arc-shaped plate 31. Initially, one end of the supporting plate 72 is in a downwardly inclined state to avoid hindering the clamping of the object. When the object is clamped and lifted off the ground, the telescopic end of the hydraulic cylinder 71 pushes the supporting plate 72 to rotate, adjusting the originally inclined supporting plate 72 to a horizontal state, and lifting the bottom of the object through one end of the supporting plate 72 to avoid the object from falling and prevent danger, meeting the usage requirements.
[0039] When placing the object, first control the rotation of the supporting plate 72 to move one end of the supporting plate 72 away from the bottom of the object, so that the bottom of the object can touch the ground. Then control the clamping claws 2 to open and drive the arc-shaped plate 31 to open to release the object, and stably move the object to the position where it needs to be placed.
