Description

Technical Field

[0001] This utility model relates to the field of automated mechanical equipment technology, and in particular to an improved automatic clamping mechanism. Background Technology

[0002] In industrial automated production, the clamping mechanism, as a core functional component, directly impacts production efficiency and product quality. However, traditional clamping mechanisms typically suffer from the following shortcomings: First, the movement flexibility of the clamping components is limited; single-rail drives or simple transmission structures struggle to adapt to multi-angle clamping requirements and precise multi-directional positioning in complex spaces, leading to clamping position deviations. Second, the control precision of the clamping force is insufficient; clamping force adjustment relies on manual experience, easily causing workpiece damage or clamping instability. Furthermore, easily damaged components such as the clamping hand are inconvenient to replace, with long adjustment cycles, affecting equipment maintenance efficiency. Therefore, there is an urgent need for an automatic clamping mechanism that can balance movement flexibility, clamping accuracy, and ease of maintenance to meet the diverse needs of modern industrial automated production. Utility Model Content

[0003] To address some of the problems existing in the prior art, this utility model provides an improved automatic clamping mechanism. This clamping mechanism has high precision, high adaptability and high-efficiency clamping capability, and is suitable for scenarios such as precise clamping, handling and positioning of workpieces in industrial automated production lines.

[0004] To achieve the above objectives, this utility model provides an improved automatic clamping mechanism, including a main frame, a first guide rail, a connecting rod, and a motor; the first guide rail is symmetrically arranged within the main frame, and the connecting rod is arranged between the first guide rails and parallel to them; a drive assembly is clamped onto the first guide rail and the connecting rod, and a drive connecting shaft is provided on the drive assembly; a clamping assembly is installed at the end of the drive connecting shaft, and the clamping assembly can rotate under the drive of the drive assembly; the motor is located at the upper end of the main frame, and the drive assembly can move up and down along the first guide rail under the drive of the motor, driving the clamping assembly to move synchronously; a sliding groove is also provided on the side end of the main frame, and an auxiliary locking assembly is embedded in the sliding groove.

[0005] When this utility model is in operation, the motor drives the drive assembly to move up and down along the first guide rail symmetrically arranged in the main frame, driving the clamping assembly at the end of the drive connecting shaft to move up and down to the designated position. After reaching the position, the drive assembly drives the clamping assembly to rotate and adjust the angle through the drive connecting shaft. Subsequently, the second drive assembly drives the mounting slider installed on the second guide rail, so that the clamping hand moves horizontally along the second guide rail until the anti-slip soft pad on the outer side of the L-shaped clamping hand's connecting plate and the inner clamping head are in contact with the workpiece. During this process, the sensor provides real-time feedback of clamping force data to accurately control the clamping force. When the clamping hand needs to be replaced, it can be disassembled and separated from the mounting slider through its mounting hole and replaced separately. After the clamping mechanism is positioned, the handle of the auxiliary locking assembly is rotated, and the threaded rod drives the abutment block to press in the slide groove on the side of the main frame. With the support plate providing stable support for the main frame, the overall mechanism is reliably locked.

[0006] The beneficial effects of this utility model are as follows: This utility model, through the first guide rail and connecting rod, in conjunction with the motor-driven drive assembly, realizes the lifting and rotating functions of the clamping assembly, significantly improving the spatial flexibility of the clamping mechanism and adapting to multi-angle and multi-directional clamping operations. The second drive assembly in the clamping assembly cooperates with the second guide rail, enabling the clamping hand to move horizontally along the direction of the second guide rail. Combined with the L-shaped clamping hand, arc-shaped connecting plate, and anti-slip pad, it effectively enhances the clamping stability and applicability for workpieces of different shapes. Simultaneously, the sensor on the surface of the clamping head provides real-time feedback of clamping force data, achieving precise control of the clamping force and preventing workpiece damage. The clamping hand is connected to the mounting slider through mounting holes, supporting individual disassembly and replacement, greatly improving the convenience of equipment maintenance. The auxiliary locking assembly, through the cooperation of the handle, threaded rod, and abutment block, reliably locks the drive assembly within the slide groove, significantly improving the overall stability of the mechanism during operation. Furthermore, the support plate on the side of the main frame further enhances the support strength of the mechanism, ensuring its reliable operation under clamping conditions.

[0007] As a further improvement of this utility model, in order to realize the independent horizontal movement of the clamping hand, expand the clamping coverage area, and support the precise positioning of complex workpieces, the clamping assembly includes a second driving assembly and a second guide rail. The second guide rail is disposed on the second driving assembly and multiple second guide rails are arranged in parallel. An installation slider is clamped on the second guide rail, and the clamping hand is mounted on the installation slider. The clamping hand moves horizontally on the second guide rail through the second driving assembly.

[0008] As a further improvement of this utility model, in order to adapt to irregular workpiece surfaces and increase friction to prevent slippage; at the same time, real-time feedback of clamping force data enables dynamic force control adjustment, avoiding workpiece damage or clamping failure; the clamping hand is generally L-shaped, and a connecting plate is installed on the bent connecting part of the clamping hand; the outer edge of the connecting plate is arc-shaped, and an anti-slip soft pad is provided on the outer side of the connecting plate; a clamping head is also provided on the inner side of the clamping hand, and multiple sensors are provided on the surface of the clamping head; the sensors are used to provide real-time feedback of clamping force data.

[0009] As a further improvement of this utility model, in order to support individual disassembly and replacement, reduce maintenance costs, and improve the convenience and efficiency of maintenance, the clamping hand is provided with multiple mounting holes, and the clamping hand is connected to the mounting slider through the mounting holes; the clamping hand can be disassembled and replaced individually.

[0010] As a further improvement of this utility model, in order to achieve secondary locking, ensure that the locking position is synchronized with the clamping action, improve locking efficiency, and enhance clamping impact resistance, the auxiliary locking component includes a mounting connecting plate. The mounting connecting plate is provided with mounting connecting holes and is connected to the drive component through the mounting connecting holes. A threaded rod is also provided on the mounting connecting plate. A clamping block is installed at one end of the threaded rod. A handle is provided at the other end of the threaded rod. The handle is rotated and drives the clamping block to press tightly in the slide groove through the threaded rod.

[0011] As a further improvement of this utility model, in order to enhance the support strength of the mechanism and ensure its reliable operation under clamping conditions, a support plate is also provided on the side of the main frame, and the main frame is stably supported by the support plate.
