DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] Embodiment 1

[0029] Reference Figure 1-3 As shown, the utility model provides a synchronous clamping mechanism, comprising:

[0030] Frame plate 20;

[0031] A sliding assembly 30, which is disposed on the frame plate 20, and the sliding assembly 30 is provided with at least two sliding ends disposed at intervals;

[0032] A pulley assembly 40, which is disposed on the frame plate 20, and the pulley assembly 40 includes at least two pulleys 41 disposed at intervals and a transmission belt 42 disposed on the pulleys 41;

[0033] The clamping assembly 50 includes a first clamping device 51 and a second clamping device 52 which are arranged at intervals; the first clamping device 51 is connected to one sliding end and is connected to the first side belt 421 of the transmission belt 42; the second clamping device 52 is connected to the other sliding end and is connected to the second side belt 422 of the transmission belt 42;

[0034] The driving device 60 is disposed on the frame plate 20 , and an output end of the driving device 60 is connected to the first clamping device 51 or the second clamping device 52 .

[0035] Specifically, the frame plate 20 serves as the basic supporting structure of the entire clamping mechanism, which provides sufficient rigidity and stability to ensure that no deformation or displacement occurs during the clamping operation, thereby ensuring the accuracy and stability of the clamping.

[0036] The sliding assembly 30 is arranged on the frame plate 20 and is equipped with at least two sliding ends arranged at intervals; the sliding end can move smoothly on the frame plate 20 to provide a stable moving platform for the clamping assembly 50; the sliding assembly 30 enables the clamping device to move accurately along a predetermined trajectory under the action of the driving device 60.

[0037] The pulley assembly 40 is also installed on the frame plate 20, and includes at least two pulleys 41 arranged at intervals and a transmission belt 42 wound around the pulleys 41; the movement of the transmission belt 42 around the pulley 41 can stably transmit power, providing a basis for ensuring the synchronous movement of the clamping assembly 50. The setting of the pulley assembly 40 can simplify the transmission structure of the clamping device and improve the efficiency and reliability of the transmission.

[0038] The clamping assembly 50 includes a first clamping device 51 and a second clamping device 52 which are arranged at intervals; the first clamping device 51 is connected to a sliding end and is connected to the first side belt 421 of the transmission belt 42; similarly, the second clamping device 52 is connected to the other sliding end and is connected to the second side belt 422 of the transmission belt 42; through the above-mentioned connection transmission method, it is ensured that when one of the first clamping device 51 or the second clamping device 52 is driven to move by the driving device 60, the other of the first clamping device 51 or the second clamping device 52 can move accordingly through the transmission of the pulley assembly 40, so that the two clamping devices can be clamped or released synchronously to achieve the technical effect of synchronous clamping.

[0039] The driving device 60 is installed on the frame plate 20, and its output end is connected to the first clamping device 51 or the second clamping device 52; when the driving device 60 is started, its output end will generate thrust or pulling force, which is transmitted through the transmission belt 42 and the sliding component 30 to make the two clamping devices move synchronously; the above-mentioned transmission structure enables a single driving device 60 to drive the first clamping device 51 and the second clamping device 52 to be clamped and released synchronously, which significantly reduces the complexity of the structure.

[0040] During operation, when it is necessary to clamp the workpiece, the driving device 60 is started to drive one of the clamping devices in the clamping assembly 50 to move under the action of the sliding assembly 30. At the same time, through the transmission of the pulley assembly 40, the other clamping device in the clamping assembly 50 moves synchronously under the action of the sliding assembly 30, so that the two clamping devices move synchronously toward the workpiece until the workpiece is firmly clamped therebetween; when it is necessary to release the workpiece, the driving device 60 moves in the opposite direction, driving the clamping devices to release synchronously.

[0041] Reference Figure 1 As shown, the sliding assembly 30 includes a guide rail 31 and a sliding block 32 slidably matched with the guide rail 31, and at least two sliding blocks 32 constitute sliding ends arranged at intervals and are respectively connected to the first clamping device 51 and the second clamping device 52.

[0042] In a specific embodiment, two guide rails 31 are provided and are spaced apart on both sides of the width direction of the frame plate 20. Limit blocks can be removably provided at both ends of the guide rails 31 to limit the movement stroke of the sliding block 32. In actual settings, other limit structures can also be used to limit the synchronous clamping mechanism. Therefore, the setting of the limit blocks is not necessary. Two sliding blocks 32 are provided on each guide rail 31 to respectively correspond to the connection with the two clamping devices in the clamping assembly 50.

[0043] Reference Figure 2-3As shown, the driving device 60 is disposed on the side of the frame plate 20 away from the clamping assembly 50 , and the output end of the driving device 60 is connected to the first clamping device 51 or the second clamping device 52 through a connecting device 70 .

[0044] In a specific embodiment, the driving device 60 adopts a cylinder device, one end of whose piston rod drives the first clamping device 51 or the second clamping device 52 to move; a through slot 21 is opened on the frame plate 20, and the connecting device 70 is arranged through the through slot 21; in the layout of this embodiment, the clamping assembly, the sliding assembly 30, the pulley assembly 40 and other structures are placed on both sides of the frame plate 20 with the cylinder device, so that the layout structure is more compact, and the setting of the cylinder will not interfere with the synchronous clamping and loosening movement; wherein the connecting device 70 may include a longitudinal connecting plate and a reinforcing rib, the longitudinal connecting plate passes through the through slot 21, and the two ends are respectively connected to a clamping device and a piston rod, and the reinforcing rib is used to enhance the stability of the connection of the longitudinal connecting plate.

[0045] Reference Figure 1-3 As shown, in a specific embodiment, the first clamping device 51 includes a first base portion 511 connected to the sliding end, a first connecting portion 512 connected to the first base portion 511, and a first clamping portion 513 connected to the first connecting portion 512, the first side band 421 of the transmission belt 42 is connected to the first base portion 511, the first connecting portion 512 is provided with a first hole 5121, and the second side band 422 of the transmission belt 42 passes through the first through hole; the second clamping device 52 includes a second base portion 521 connected to the sliding end, a second connecting portion 522 connected to the second base portion 521, and a second clamping portion 523 connected to the second connecting portion 522, a second hole 5211 is provided between the second base portion 521 and the frame plate body 20, the first side band 421 of the transmission belt 42 passes through the second hole 5211, and the first side band 421 of the transmission belt 42 is connected to the second connecting portion 522.

[0046] Among them, the first base part 511, the first connecting part 512, the second base part 521, and the second connecting part 522 can all be composed of a combination of plate structures to ensure sufficient structural strength and clamping stability, and the fixed position between the transmission belt 42 and the clamping device is usually located in the middle to avoid shaking and deviation of the clamping device during movement and improve stability.

[0047] Reference Figure 1As shown, the first clamping device 51 also includes a first fixing plate 5111 detachably connected to the first base portion 511, and the first fixing plate 5111 fixes the first side band 421 of the transmission belt 42 to the first connecting portion 512; the second clamping device 52 also includes a second fixing plate 5221 detachably connected to the second connecting portion 522, and the second fixing plate 5221 fixes the second side band 422 of the transmission belt 42 to the second connecting portion 522.

[0048] Specifically, the first fixing plate 5111 can be connected to the first base by bolts, clips or other quick-release structures, and the second fixing plate 5221 can be connected to the second connecting part 522 by bolts, clips or other quick-release structures to facilitate installation and disassembly; through the above arrangement, during the clamping operation, the transmission belt 42 is not easy to slip or fall off, and is easy to disassemble and maintain and replace, and also allows the staff to adjust the position of the fixing plate or replace fixing plates of different specifications according to actual needs to adapt to transmission belts 42 of different widths or types.

[0049] Reference Figure 2 As shown, the first clamping portion 513 and the second clamping portion 523 are arranged opposite to each other, and both ends of the first clamping portion 513 and the second clamping portion 523 are provided with guiding inclined surfaces 5231 .

[0050] Specifically, the relatively arranged clamping parts work together to achieve stable clamping of the object; the setting of the guiding slope 5231 on the clamping part can guide the object to smoothly enter the clamping area, avoiding clamping difficulties caused by deviations in the shape or position of the object.

[0051] In some embodiments, the clamping assembly 50 is provided with one or more groups; wherein, in each group of the clamping assembly 50, the first clamping device 51 and the second clamping device 52 are arranged opposite to each other, and are driven by the driving device 60 to perform synchronous movement towards or away from each other. In this type of embodiment, a group of pulley assemblies 40 drives multiple groups of clamping assemblies 50 to implement clamping and loosening, thereby improving work efficiency. It is generally suitable for use scenarios with limited space and large-scale production operations.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
