Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of clamping devices, and in particular relates to a separate clamping mechanism. Background Art
[0002] At present, most of the automated clamping equipment in various industries (such as the panel industry) adopts the traditional cylinder clamping method. This traditional cylinder clamping method requires one cylinder to correspond to one fixed point, and the cylinder needs to be connected with the positioning fixture. It is relatively fixed to use, and the equipment is bulky and not flexible enough. Therefore, it is difficult to cope with some complex and changeable working conditions. A large number of clamping cylinders are required for use, and the cost is high. Therefore, the existing clamping equipment needs to be improved. Utility Model Content
[0003] The purpose of the utility model is to provide a separate clamping mechanism to solve the above problems existing in the prior art.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A separate clamping mechanism comprises a first sub-mechanism and a second sub-mechanism which are separately arranged, wherein the first sub-mechanism is used for lifting and lowering in the vertical direction, and the second sub-mechanism is used for telescoping and extending in the horizontal direction. The first sub-mechanism squeezes the second sub-mechanism during the vertical rising process, so that the second sub-mechanism is compressed in the horizontal direction and detaches from the target object, and the first sub-mechanism releases the second sub-mechanism during the vertical descending process, so that the second sub-mechanism pops out in the horizontal direction to clamp the target object.
[0006] When it is used, the first sub-mechanism upward squeezes the second sub-mechanism, so that the second sub-mechanism is in a state of being compressed in the horizontal direction. If it is necessary to clamp the target object, the first sub-mechanism can be vertically lowered, and the first sub-mechanism gradually releases the second sub-mechanism during the vertical descent, so that the second sub-mechanism slowly pops out in the horizontal direction to clamp the target object. In the state where the second sub-mechanism clamps the target object, if it is necessary to detach from the target object, the first sub-mechanism can be vertically raised, and the first sub-mechanism gradually squeezes the second sub-mechanism during the vertical rise, so that the second sub-mechanism slowly detaches from the target object in the horizontal direction. Since the first sub-mechanism and the second sub-mechanism are separately arranged, after the second sub-mechanism clamps the target object, the second sub-mechanism can be used alone to clamp the target object for other operations. The application is more flexible and convenient, and is suitable for a variety of clamping operation scenarios.
[0007] In a possible design, the first sub-mechanism includes a lifting device and a pressing component, and the pressing component is installed at the lifting end of the lifting device and is used to contact the second sub-mechanism to press or release the second sub-mechanism.
[0008] When it is used, the lifting device can be used to drive the pressing component to rise or fall. During the rising process of the lifting device, the pressing component contacts the second sub-mechanism and squeezes the second sub-mechanism to make it horizontally compressed. During the descending process of the lifting device, the pressing component gradually releases the second sub-mechanism to make it pop out horizontally.
[0009] In a possible design, the pressing component is detachably connected to the lifting device. When used, the detachable connection facilitates assembly, use, and disassembly and maintenance of the pressing component and the lifting device.
[0010] In a possible design, the lifting device includes a cylinder. When used, the cylinder can achieve stable and controllable lifting operations. At the same time, since the cylinder only performs short-stroke lifting operations and is separated from the second sub-mechanism, the cylinder will not perform other synchronous movements with the target object, and its air pipe will not be entangled, which is safer and easier to use.
[0011] In a possible design, the pressing component includes a rotatable top wheel, and the top wheel forms rolling friction with the second sub-mechanism during the process of squeezing or releasing the second sub-mechanism. When used, the top wheel is provided to form rolling friction with the second sub-mechanism during the process of squeezing or releasing the second sub-mechanism, thereby reducing the friction coefficient and making the clamping operation process smoother.
[0012] In a possible design, the second sub-mechanism includes an oblique push block, an elastic component and a clamping component. The oblique push block is used to contact the first sub-mechanism, and the end of the oblique push block that contacts the first sub-mechanism is provided with a slope surface, so that the first sub-mechanism abuts against the slope surface during vertical ascent or descent, and moves relative to the oblique push block. One end of the elastic component is connected to the oblique push block, and the other end is connected to an external object, and the elastic component is used to extend and retract in the horizontal direction. The clamping component is installed on the oblique push block, and is used to clamp or detach from the target object in the horizontal direction.
[0013] When it is used, when the first sub-mechanism rises, it contacts the slope surface on the oblique push block and forms an oblique pressure on the oblique push block, so that the oblique push block squeezes the elastic component and drives the clamping component to perform a target object separation movement. When the first sub-mechanism descends, it moves relative to the slope surface of the oblique push block, so that the oblique push block drives the clamping component to perform a target object clamping movement under the elastic force of the elastic component.
[0014] In a possible design, the oblique push block is detachably connected to the elastic component and the clamping component. When used, the detachable connection method facilitates the assembly, use, and disassembly and maintenance of the oblique push block, the elastic component, and the clamping component.
[0015] In a possible design, the elastic component includes a spring. When used, the spring can achieve effective telescopic movement, making it easy to use elastic force to clamp the target object, and the spring is inexpensive and easy to use.
[0016] In a possible design, the clamping component includes a positioning guide wheel. When used, it can achieve efficient position-limited clamping of the target object.
[0017] In a possible design, at least two groups of the first sub-mechanism and the second sub-mechanism are provided. When used, by providing at least two groups of the first sub-mechanism and the second sub-mechanism, the target object can be stably clamped from different directions, thereby improving the safety and stability of the target object clamping operation.
[0018] Beneficial effects: The utility model effectively solves the problems of traditional clamps with single application scenarios, large space occupation and high application costs through a separate structural design; it is suitable for side change detection after clamping the target object and various complex working conditions, and the structure is simple to operate, occupies a small space, and will not cause pipeline entanglement, which can effectively improve the aesthetics and reliability of the mechanism; at the same time, it is more flexible and convenient to use and is suitable for a variety of clamping operation scenarios.

[0023] It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structural and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments described herein.
[0024] It should be understood that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or a direct connection; it can be an indirect connection through an intermediate medium, or it can be a communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments can be understood according to specific circumstances.
[0025] In the following description, certain details are provided to facilitate a complete understanding of the example embodiments. However, it will be appreciated by those of ordinary skill in the art that the example embodiments may be implemented without these certain details. For example, the system may be shown in a block diagram to avoid obscuring the example with unnecessary details. In other embodiments, well-known processes, structures, and techniques may not be shown in unnecessary detail to avoid obscuring the embodiments.
[0026] Example:
[0027] like Figure 1 to Figure 2 As shown, this embodiment provides a separate clamping mechanism, including a first sub-mechanism and a second sub-mechanism that are separately arranged, the first sub-mechanism is used for lifting and lowering operations in the vertical direction, and the second sub-mechanism is used for telescoping operations in the horizontal direction, the first sub-mechanism squeezes the second sub-mechanism during the vertical rising process, so that the second sub-mechanism is compressed in the horizontal direction and detaches from the target object 6, and the first sub-mechanism releases the second sub-mechanism during the vertical descending process, so that the second sub-mechanism pops out in the horizontal direction to clamp the target object 6.
[0028] In specific implementation, the first sub-mechanism and the second sub-mechanism which are separately arranged can be installed separately, such as installing the first sub-mechanism on the ground and installing the second sub-mechanism on other production equipment, so that the first sub-mechanism and the second sub-mechanism are used in matching manner. When the first sub-mechanism upwardly squeezes the second sub-mechanism so that the second sub-mechanism is compressed in the horizontal direction, if it is necessary to clamp the target object 6, the first sub-mechanism can be vertically lowered, and the first sub-mechanism gradually releases the second sub-mechanism during the vertical descent process, so that the second sub-mechanism slowly pops out in the horizontal direction to clamp the target object 6. When the second sub-mechanism is clamping the target object 6, if it is necessary to detach from the target object 6, the first sub-mechanism can be vertically raised, and the first sub-mechanism gradually squeezes the second sub-mechanism during the vertical rise process, so that the second sub-mechanism slowly detaches from the target object 6 in the horizontal direction. Since the first sub-mechanism and the second sub-mechanism are separately arranged, after the second sub-mechanism clamps the target object 6, the second sub-mechanism can be used alone to clamp the target object 6 to perform other complex actions, which is more flexible and convenient to use and is suitable for a variety of clamping operation scenarios. For example, when the second sub-mechanism is installed on the stage, after the second sub-mechanism clamps the glass, the glass can be rotated on the stage, thereby realizing scenes such as edge change detection. The first sub-mechanism and the second sub-mechanism are provided with at least two groups. By providing at least two groups of the first sub-mechanism and the second sub-mechanism, the target object 6 can be stably clamped from different directions, thereby improving the safety and stability of the clamping operation of the target object 6.
[0029] Furthermore, the first sub-mechanism includes a lifting device 1 and a pressing component 2, and the pressing component 2 is installed at the lifting end of the lifting device 1, and is used to contact with the second sub-mechanism, squeeze or release the second sub-mechanism. In specific implementation, the lifting device 1 can drive the pressing component 2 to ascend or descend. During the ascending process of the lifting device 1, the pressing component 2 contacts with the second sub-mechanism and squeezes the second sub-mechanism to make it horizontally compressed. During the descending process of the lifting device 1, the pressing component 2 gradually releases the second sub-mechanism to make it pop out horizontally. In addition, the pressing component 2 is detachably connected to the lifting device 1. In specific implementation, the detachable connection method facilitates the assembly, use, disassembly and maintenance of the pressing component 2 and the lifting device 1.
[0030] Further, the lifting device 1 may include a cylinder, which is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. It is mainly composed of a cylinder barrel, a cylinder head, a piston, a piston rod and a seal, etc. It converts the pressure of compressed air into mechanical energy through pneumatic transmission, so that the mechanism performs linear reciprocating motion or swinging and rotating motion. The cylinder can achieve stable and controllable lifting operations. At the same time, since the cylinder only performs short-stroke lifting operations and is separated from the second sub-mechanism, the cylinder will not perform other synchronous movements with the target object 6, and its air pipe will not be entangled, which is safer and simpler to use. Alternatively, as an alternative, the lifting device 1 may include a stepper motor, which is an electric motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. For each input of a pulse signal, the rotor rotates an angle or moves forward one step, and the angular displacement or linear displacement output is proportional to the number of input pulses, and the speed is proportional to the pulse frequency. The stepper motor can achieve more precise lifting operation control, and there is no need to provide a corresponding pneumatic pipeline, and there is no entanglement of the air pipe. Other types of lifting devices 1 may also be selected according to actual conditions.
[0031] The pressing component 2 includes a rotatable top wheel, which forms rolling friction with the second sub-mechanism during the process of squeezing or releasing the second sub-mechanism. In specific implementation, by setting the top wheel, rolling friction is formed with the second sub-mechanism during the process of squeezing or releasing the second sub-mechanism, the friction coefficient is reduced, and the clamping operation process is smoother. As an alternative, the pressing component 2 can also be a component that forms sliding friction with the second sub-mechanism during the process of squeezing or releasing the second sub-mechanism, and then the contact surface of the pressing component 2 and the second sub-mechanism is coated with corresponding lubricating oil or lubricant to reduce friction, so that the clamping operation process is smoother.
[0032] Furthermore, the second sub-mechanism includes an oblique push block 3, an elastic component 4 and a clamping component 5, the oblique push block 3 is used to contact the first sub-mechanism, and the end of the oblique push block 3 that contacts the first sub-mechanism is provided with a slope surface, so that the first sub-mechanism abuts against the slope surface during vertical ascent or vertical descent, and performs relative movement with the oblique push block 3, one end of the elastic component 4 is connected to the oblique push block 3, and the other end is connected to an external object, and the elastic component 4 is used to extend and retract in the horizontal direction, and the clamping component 5 is installed on the oblique push block 3, and is used to clamp or detach from the target object 6 in the horizontal direction.
[0033] In specific implementation, when the lifting device 1 of the first sub-mechanism rises, it drives the pressing component 2 to contact the slope surface on the oblique push block 3, and forms an oblique pressure on the oblique push block 3, so that the oblique push block 3 squeezes the elastic component 4, drives the clamping component 5 to perform the target object 6 disengagement movement, and finally makes the clamping component 5 disengage from the target object 6. When the lifting device 1 of the first sub-mechanism descends, its pressing component 2 moves relative to the slope surface of the oblique push block 3, so that the oblique push block 3 drives the clamping component 5 to perform the target object 6 clamping movement under the elastic force of the elastic component 4, and finally makes the clamping component 5 stably clamp the target object 6. The oblique push block 3 is detachably connected to the elastic component 4 and the clamping component 5. In specific implementation, the detachable connection method facilitates the assembly, use, disassembly and maintenance of the oblique push block 3, the elastic component 4 and the clamping component 5.
[0034] Furthermore, the elastic component 4 includes a spring. In a specific implementation, the spring can realize effective telescopic movement, and it is convenient to use elastic force to clamp the target object 6, and the spring is cheap and easy to use. The spring can be a leaf spring, a coil spring, a torsion bar spring, a rubber spring or a gas spring, among which the coil spring is the most widely used elastic element, which is cheap, light in structure, and does not require much space for arrangement. Or as an alternative, the elastic component 4 can be other types of elastic elements such as an elastic diaphragm.
[0035] The clamping component 5 includes a positioning guide wheel. In specific implementation, efficient position limiting clamping of the target object 6 can be achieved. Alternatively, as an alternative, the clamping component 5 can use a position limiting clamping device with corresponding position limiting grooves to efficiently position limit clamping the target object 6.
[0036] The separate clamping mechanism provided in this embodiment effectively solves the problems of traditional clamps having a single application scenario, occupying a large space, and having a high application cost through a separate structural design; it is suitable for side change detection after clamping the target object and various complex working conditions, and the structure is simple to operate, occupies a small space, and does not cause pipeline entanglement, which can effectively improve the aesthetics and reliability of the mechanism; at the same time, it is more flexible and convenient to use and is suitable for a variety of clamping operation scenarios.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
