[0020] This utility model proposes a bidirectional clamping mechanism 100.

[0021] Please see Figure 1 In one embodiment of the present invention, the bidirectional clamping mechanism 100 includes a base 1, a clamping component 2, and a moving component 3. The clamping component 2 is movably disposed on the base 1 along a first direction. The driving end of the moving component 3 is connected to the base 1, and the moving component 3 is configured to drive the base 1 and the clamping component 2 to move along a second direction. The first direction and the second direction are linear directions that are set at an angle.

[0022] In this embodiment, the bidirectional clamping mechanism 100 can be applied to industrial automation production, logistics, and other scenarios. The base 1 provides a stable mounting platform for the clamping assembly 2 and the moving assembly 3. The clamping assembly 2 is used to clamp and fix objects. The moving assembly 3 is used to drive the base 1 and the clamping assembly 2 to move along a second direction. It should be noted that when the clamping assembly 2 cooperates with other structures, due to the large gap between the clamping assembly 2 and other structures, the moving assembly 3 needs to move it closer to the other structures. The first direction is the clamping direction of the clamping assembly 2, i.e. Figure 1 The direction of the double-headed arrow X is the first direction, and the second direction is the movement direction of the moving component 3. Figure 1 The direction of the double-headed arrow Y. The first direction and the second direction can also be that the first direction is... Figure 1 The first direction is the direction of the double-headed arrow X, but the second direction can be an angled direction with the double-headed arrow X, which can drive the clamping assembly 2 to move up and down. It is understood that the clamping assembly 2 is movably mounted on the base 1 along the first direction, which is usually achieved through mechanical structures such as sliding or rotation. The driving end of the moving assembly 3 is connected to the base 1, and its working principle is mainly to use a power source (such as a motor, cylinder, etc.) to generate power, which drives the base 1 and the clamping assembly 2 to move along the second direction through a transmission mechanism (such as belt drive, gear drive, screw drive, etc.). In one embodiment, a slide rail is provided on the base 1, and the clamping assembly 2 is mounted on the slide rail via a slider. The motor is connected to the slider through a screw drive mechanism. When the motor rotates, the screw rotates, driving the slider to move along the slide rail, thereby realizing the movement of the clamping assembly 2 in the first direction. Simultaneously, the moving assembly 3 can adopt a similar motor-driven screw drive method, with the screw connected to the base 1. The rotation of the motor drives the screw to rotate, causing the base 1 to move along the second direction. In another embodiment, a rack along a first direction is mounted on the base 1, and the clamping assembly 2 meshes with the rack via gears. A motor drives the gears to rotate, and the movement of the rack causes the clamping assembly to move along the first direction. A rack along a second direction is mounted on the bottom or side of the base 1, and a moving assembly 3 meshes with the rack via gears. A motor drives the gears to rotate, and the movement of the rack causes the base 1 and the clamping assembly 2 to move along the second direction.

[0023] The bidirectional clamping mechanism 100 provided by this utility model, through the combined design of a base 1, a clamping assembly 2, and a moving assembly 3, solves the problem of insufficient flexibility and inability to meet multi-directional handling needs of traditional clamping devices when operating in a single direction. Specifically, the clamping assembly 2 is movably mounted on the base 1 along a first direction, allowing it to extend, retract, or rotate in that direction to clamp and release goods. Simultaneously, the driving end of the moving assembly 3 is connected to the base 1 and configured to drive the base 1 and the clamping assembly 2 to move along a second direction. This means the entire clamping mechanism can operate not only in the first direction but also move as a whole in the second direction, greatly expanding its operating range and flexibility. The base 1, as the supporting foundation of the entire mechanism, provides a stable mounting platform for the clamping assembly 2 and the moving assembly 3. The mobility of the clamping assembly 2 ensures that it can be adaptively adjusted according to the size and shape of the goods in the first direction to achieve clamping. The moving assembly 3, on the other hand, gives the entire mechanism the ability to move in the second direction, improving work efficiency. This design not only overcomes the limitations of traditional clamping devices operating in a single direction, but also enhances the versatility and adaptability of the clamping mechanism through multi-directional movement capabilities, enabling it to better meet complex and ever-changing logistics handling needs. The bidirectional clamping mechanism 100 significantly improves handling efficiency and flexibility. By enabling operation in two different directions, it reduces adjustment time and steps during cargo handling, lowers the need for manual intervention, and also improves the stability and safety of the handling process. Furthermore, this design is better suited to handling tasks in different scenarios. For example, in confined spaces or situations requiring multi-directional operation, the bidirectional clamping mechanism 100 demonstrates greater advantages, showcasing higher practicality and economy.

[0024] In one embodiment of the present invention, the moving component 3 includes a first guide rail 31, a first driving member 32 and a fixed plate 33. The first guide rail 31 and the first driving member 32 are both disposed on the fixed plate 33. The base 1 is slidably disposed on the moving component 3. The driving end of the first driving member 32 is connected to the base 1.

[0025] In this embodiment, combined with Figure 2 To achieve stable movement of the base 1, a first guide rail 31 and a first driving component 32 are provided on the fixed plate 33. The first driving component 32 drives the base 1 to move bidirectionally along the extension direction of the first guide rail 31. It is understood that the type of the first driving component 32 includes, but is not limited to, a motor, a cylinder, etc., and here a servo motor is preferred. The first guide rail 31 is arranged along the extension direction of the fixed plate 33 and is linear. The base 1 moves linearly along the linear guide rail under the drive of the first driving component 32. Figure 2A slider is set on the base 1, and the base 1 is slidably connected to the first guide rail 31 through the slider. The size of the slider is adapted to the size of the first guide rail 31.

[0026] In one embodiment of the present invention, the moving component 3 further includes a plurality of first sensors 34, each first sensor 34 being disposed on one side of the first guide rail 31, and each first sensor 34 being configured to limit the moving distance of the base 1.

[0027] In this embodiment, combined with Figure 2 To precisely control the movement range, multiple first sensors 34 are arranged on one side of the first guide rail 31, ensuring that the base 1 can only move within a set range, preventing collisions or exceeding the working area due to excessive movement. It should be noted that the types of first sensors 34 include, but are not limited to, photoelectric sensors, position sensors, and displacement sensors; position sensors are preferred here. The number of position sensors is not limited and can be set according to specific requirements. Figure 2 It is understood that the moving component 3 includes three position sensors. The three position sensors are spaced apart on one side of the fixed plate 33 and are located near the first guide rail 31. The base 1 has a sensing plate on the side near the position sensor. The sensing plate contacts the position sensor to determine whether the movement of the base 1 exceeds the range.

[0028] In one embodiment of this utility model, the driving end of the first driving member 32 is provided with a lead screw 321 and a lead screw nut, and the lead screw nut is connected to the base 1.

[0029] In this embodiment, combined with Figure 2 To precisely control movement, high-precision displacement control is achieved through the threaded transmission of the lead screw 321 and lead screw nut. The pitch of the lead screw 321 determines the moving distance of the base 1, thus allowing for precise control of the base 1's position. The lead screw 321 and lead screw nut achieve transmission through threaded engagement. When the first driving element 32 (such as a motor) drives the lead screw 321 to rotate, the lead screw nut moves along the axial direction of the lead screw 321. Since the lead screw nut is connected to the base 1, the base 1 moves along the first guide rail 31 as the lead screw nut moves. It is understood that the first driving element 32 here is in the form of a motor, and the motor's output shaft is connected to the lead screw 321 via a coupling. The motor receives control signals through a controller, drives the lead screw 321 to rotate, and the lead screw nut moves along the lead screw 321, thereby causing the base 1 to move along the first guide rail 31.

[0030] In one embodiment of the present invention, the clamping assembly 2 includes two clamping arms 21 arranged opposite to each other, and the two clamping arms 21 are movably disposed on the base 1 along a first direction.

[0031] In this embodiment, combined with Figure 1 and Figure 2 Two opposing clamping arms 21 can firmly hold an object, ensuring that the object will not loosen or fall off during movement or processing. The two clamping arms 21 are positioned opposite each other, and a cylinder or motor moves the clamping arms 21 inwards or outwards to clamp or release the object. It should be noted that the first direction... Figure 1 The direction of the double-headed arrow X. In one embodiment, a cylinder is used as the drive mechanism, with the piston rod of the cylinder connected to the clamping arm 21. The extension and retraction of the cylinder is controlled by a pneumatic control system (such as a solenoid valve), thereby driving the clamping arm 21 to move in the first direction. In another embodiment, a hydraulic cylinder can be used as the drive mechanism, with the piston rod of the hydraulic cylinder connected to the clamping arm 21. The extension and retraction of the hydraulic cylinder is controlled by a hydraulic control system (such as a hydraulic pump or a solenoid valve), thereby driving the clamping arm 21 to move. No limitation is made here.

[0032] In one embodiment of the present invention, one end of each clamping arm 21 is connected to a driving part, which is disposed on the base 1. The driving part can drive one clamping arm 21 to move toward the other clamping arm 21.

[0033] In this embodiment, combined with Figure 2 and Figure 3 By driving the clamping arm 21 to move towards another clamping arm 21 through the drive unit, precise clamping of the object can be achieved, ensuring uniform and reliable clamping force. It is understood that the drive unit can be driven by, but is not limited to, motor-driven, pneumatic-driven, piezoelectric-driven, etc., as described in the next embodiment.

[0034] In one embodiment of the present invention, the driving unit includes a second driving member 22 and a second guide rail 23. The second guide rail 23 is disposed on the base 1. Each clamping arm 21 is provided with a connector 24 at one end near the second guide rail 23. The connector 24 is slidably connected to the second guide rail 23 and is connected to the driving end of the second driving member 22.

[0035] In this embodiment, the type of the second driving component 22 includes, but is not limited to, a stepper motor, a servo motor, etc., and is preferably a servo motor. It should be noted that, in conjunction with... Figure 2 and Figure 3 A second guide rail 23 is provided at each of the opposite ends of the base 1. Each connector 24 has a slider on the side near the second guide rail 23, which is slidably connected to the second guide rail 23. This provides higher guiding accuracy and stability, reduces the shaking and error of the clamping arm 21 during movement, and further improves the clamping accuracy. The driving end of the second drive member 22 is also provided with a moving lead screw and a lead screw fixing nut. The left and right movement of the moving lead screw drives the first slider and the second slider to move, thereby driving the clamping arm 21 to move.

[0036] In one embodiment of the present invention, the clamping assembly 2 further includes two second sensors 25, which are respectively disposed at opposite ends of the base 1, and each second sensor 25 is configured to detect the displacement of a clamping arm 21.

[0037] In this embodiment, combined with Figure 2 To further ensure the limitation of the running distance of the two clamping arms 21, a second sensor 25 is provided at each of the opposite ends of the base 1. The type of the second sensor 25 here includes, but is not limited to, photoelectric sensor, position sensor, displacement sensor, etc. Position sensor is preferred here, and the number of position sensors is not limited and can be set according to specific needs.

[0038] In one embodiment of the present invention, the driving unit includes two second guide rails 23 spaced apart, the two second guide rails 23 extending along a second direction, the connecting member 24 being slidably connected to the two second guide rails 23 respectively, and the second driving member 22 being located between the two second guide rails 23.

[0039] In this embodiment, combined with Figure 2 and Figure 3 It should be noted that two second guide rails 23 are respectively provided at each of the opposite ends of the base 1. The connecting piece 24 has a first slider and a second slider on the side near the second guide rails 23. The first slider and the second slider are slidably connected to the two second guide rails 23, which provides higher guiding accuracy and stability, reduces the shaking and error of the clamping arm 21 during movement, and further improves the clamping accuracy. The driving end of the second driving piece 22 is also provided with a moving lead screw and a lead screw fixing nut. The left and right movement of the moving lead screw drives the first slider and the second slider to move, thereby driving the clamping arm 21 to move.

[0040] In one embodiment of the present invention, the bidirectional clamping mechanism 100 further includes a controller, which is communicatively connected to the clamping component 2 and the moving component 3 respectively.

[0041] In this embodiment, to improve control accuracy, the bidirectional clamping mechanism 100 also includes a controller (not shown in the figure). The type of controller includes, but is not limited to, a programmable logic controller (PLC), a motion controller, etc., preferably in the form of a PLC. It outputs a product positioning command signal to the second drive member 22 of the clamping assembly 2 and the first drive member 32 of the moving assembly 3, so that the clamping arm 21 of the clamping assembly 2 moves along the first direction under the second drive. Figure 1 The double-headed arrow moves in the X direction, and the moving component 3 moves along the second direction, i.e. Figure 1 The bidirectional arrow moves in the Y direction, which in turn moves the base 1 along the second direction. When there is a positional deviation, the first drive component 32 and the second drive component 22 adjust the spacing by rotating forward and backward to ensure accurate positioning.
