[0035] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0036] The fixture is used to clamp the workpiece and realize the clamping and positioning of the workpiece. In the prior art, the fixture can realize the clamping and positioning of workpieces of the same type and size, but it is difficult to clamp and position workpieces of different types and sizes.

[0037] In order to solve the technical problem of the difficulty in clamping and positioning workpieces of different types and sizes, this application provides a clamp, please refer to Figure 1 The clamp includes a frame 10 , a driving assembly (not shown in the figure), a first gear 30 , a second gear 40 , a first clamp arm 50 and a second clamp arm 60 .

[0038] The frame 10 provides a mounting base, and the driving assembly is installed and connected to the frame 10. The first gear 30 and the second gear 40 are meshed and connected, and the first gear 30 and the second gear 40 are respectively connected to the frame 10, and the driving end of the driving assembly is in transmission connection with the first gear 30. Since the first clamping arm 50 is connected to the first gear 30, and the second clamping arm 60 is connected to the second gear 40, when the driving end of the driving assembly drives the first gear 30 to rotate, the first clamping end 51 of the first clamping arm 50 away from the first gear 30 and the second clamping end 61 of the second clamping arm 60 away from the second gear 40 can be moved closer or farther away, so that when the first clamping end 51 and the second clamping end 61 are close to each other, the workpiece is clamped; when the first clamping end 51 and the second clamping end 61 are far away from each other, the workpiece is placed and positioned.

[0039] At the same time, by controlling the rotation angle of the first gear 30 through the driving component and adjusting the distance between the first clamping end 51 and the second clamping end 61, the clamping and positioning of workpieces of different types and sizes can be adapted, and the accuracy and convenience of the clamping and positioning of workpieces of different types and sizes can be improved.

[0040] In order to improve the convenience of transmission connection between the driving assembly and the first gear 30, please refer to Figures 2 to 3The driving assembly includes a motor 21, a first driving rod 22, a second driving rod 23 and a connecting rod 24. The first driving rod 22 is fixedly connected to the driving end of the motor 21 (the fixed connection method can be welding or threaded connection, etc.), the second driving rod 23 is fixedly connected to the first clamping arm 50 (the fixed connection method can be welding or threaded connection, etc.), and the connecting rod 24 is telescopically connected between the end of the first driving rod 22 away from the motor 21 and the end of the second driving rod 23 away from the first clamping arm 50. When the driving end of the motor 21 drives the first driving rod 22 to rotate, the first driving rod 22 can drive the second driving rod 23 to rotate in the same direction through the connecting rod 24, and the first clamping arm 50 is connected to the first gear 30, thereby driving the first gear 30 to rotate. The transmission connection between the driving end of the motor 21 and the first clamping arm 50 can be realized through the first driving rod 22, the connecting rod 24 and the second driving rod 23. The structure is simple, the transmission efficiency between the driving end of the motor 21 and the first clamping arm 50 can be improved, the cost can be saved, and the technical and economic benefits can be improved.

[0041] In some embodiments, the second driving rod 23 can be fixedly connected to the first gear 30, and the motor 21 drives the first gear 30 to rotate through the first driving rod 22, the connecting rod 24 and the second driving rod 23. The first clamping arm 50 is fixedly connected to the first gear 30, thereby driving the first clamping arm 50 to rotate.

[0042] In order to prevent the first driving rod 22 from having a dead point during the rotation connection with the second driving rod 23 through the connecting rod 24, please refer to Figures 2 to 3 The connecting rod 24 includes an adapter shaft 241, a first adapter 242 and a second adapter 243, and the first adapter 242 and the second adapter 243 are respectively threadedly connected to the two ends of the adapter shaft 241. The first adapter 242 is movably connected to the first drive rod 22, and the second adapter 243 is movably connected to the second drive rod 23. Since the threads at the two ends of the adapter shaft 241 have the same rotation direction, the length of the first adapter 242 and the second adapter 243 extending into or out of the adapter shaft 241 can be adjusted by rotating the adapter shaft 241. In this way, the length of the whole composed of the first adapter 242, the second adapter 243 and the adapter shaft 241 can be adjusted according to actual needs, thereby ensuring that the first clamping end 51 and the second clamping end 61 meet the position space requirements of the workpiece clamping, while preventing the first drive rod 22 from having a dead point during the rotation connection with the second drive rod 23 through the connecting rod 24, and ensuring the stability and smoothness of the first clamping arm 50 and the second clamping arm 60 in clamping and positioning the workpiece.

[0043] It should be noted that the present application does not limit the manner in which the first adapter 242 is movably connected to the first driving rod 22 , and the second adapter 243 is movably connected to the first clamping arm 50 , and these can be set according to actual needs.

[0044] At the same time, in order to further prevent the occurrence of a dead point during the rotational connection between the first drive rod 22 and the second drive rod 23 through the connecting rod 24, the second drive rod 23 is set at an angle to the first clamping arm 50. In this way, by adjusting the length of the entirety composed of the first adapter 242, the second adapter 243 and the adapter shaft 241 and / or the angle between the second drive rod 23 and the first clamping arm 50, the occurrence of a dead point during the rotational connection between the first drive rod 22 and the second drive rod 23 through the connecting rod 24 is prevented, thereby ensuring the stability and smoothness of the first clamping arm 50 and the second clamping arm 60 in clamping and positioning the workpiece.

[0045] In order to improve the connection stability between the first gear 30 and the first clamp arm 50, and the connection stability between the second gear 40 and the second clamp arm 60, please refer to Figures 2 to 3 The clamp further includes a first rotating shaft 70 and a second rotating shaft 80. The first rotating shaft 70 is rotatably connected to the frame body 10, and the first gear 30 and the first clamp arm 50 are sequentially passed through the first rotating shaft 70 and are respectively fixedly connected to the first rotating shaft 70. The first gear 30 and the first clamp arm 50 are respectively positioned and connected to the first rotating shaft 70 through keyways, which can improve the stability of the connection between the first gear 30 and the first clamp arm 50 through the first rotating shaft 70, and the first gear 30 can be driven to rotate through the first rotating shaft 70 as the first clamp arm 50 rotates.

[0046] The second rotating shaft 80 is rotatably connected to the frame body 10 and is spaced apart from the first rotating shaft 70. The second gear 40 and the second clamp arm 60 are sequentially passed through the second rotating shaft 80 and are respectively fixedly connected to the second rotating shaft 80. The second gear 40 and the second clamp arm 60 are respectively positioned and connected to the second rotating shaft 80 through keyways, which can improve the stability of the connection between the second gear 40 and the second clamp arm 60 through the second rotating shaft 80. As the second clamp arm 60 rotates, the second gear 40 can be driven to rotate through the second rotating shaft 80.

[0047] In order to improve the stability of the first rotating shaft 70 and the second rotating shaft 80 respectively connected to the frame 10, please refer to Figures 1 to 3 The fixture further includes a first support seat 71 and a second support seat 81. The second support seat 81 is spaced apart from the first support seat 71. The first rotating shaft 70 is rotatably connected to the first support seat 71. The first support seat 71 is used to support the rotation of the first rotating shaft 70, thereby improving the stability of the rotational connection between the first rotating shaft 70 and the frame 10. The second rotating shaft 80 is rotatably connected to the second support seat 81. The second support seat 81 is used to support the rotation of the second rotating shaft 80, thereby improving the stability of the rotational connection between the second rotating shaft 80 and the frame 10.

[0048] The first support seat 71 and the second support seat 81 are respectively installed with bearings, and the first rotating shaft 70 is rotatably connected to the first support seat 71 through the bearings, and the second rotating shaft 80 is rotatably connected to the second support seat 81 through the bearings, thereby improving the smoothness of the rotational connection between the first rotating shaft 70 and the first support seat 71, and the smoothness of the rotational connection between the second rotating shaft 80 and the second support seat 81.

[0049] There are at least two groups of first support seats 71 and second support seats 81 respectively, the first rotating shaft 70 is sequentially passed through the two groups of first support seats 71, and the second rotating shaft 80 is sequentially passed through the two groups of second support seats 81, which can further improve the stability of the rotational connection between the first rotating shaft 70 and the frame 10, and the stability of the rotational connection between the second rotating shaft 80 and the frame 10.

[0050] A protective plate 90 is provided on one side of the first support seat 71 and the second support seat 81 close to the first gear 30 and the second gear 40. The protective plate 90 is installed on the same side of the first support seat 71 and the second support seat 81 to prevent the bearing from detaching from the first support seat 71 or the second support seat 81, thereby improving the stability of the bearing installation in the first support seat 71 or the second support seat 81. At the same time, it can also prevent the operation of the first gear 30 and the second gear 40 from being affected, thereby improving the stability and smoothness of the meshing operation of the first gear 30 and the second gear 40. In some embodiments, the protective plate 90 can also be installed on the frame 10, which can be specifically set according to actual needs, and this application does not limit it.

[0051] In some embodiments, the first clamp arm 50 is fixedly connected to the side of the first gear 30, and the first clamp arm 50 is connected to the first gear 30 by welding or bolting. The second clamp arm 60 is fixedly connected to the side of the second gear 40, and the second clamp arm 60 is connected to the second gear 40 by welding or bolting. The manner in which the first clamp arm 50 is fixedly connected to the first gear 30 is not limited in this application and can be set according to actual needs. The manner in which the second clamp arm 60 is fixedly connected to the second gear 40 is not limited in this application and can be set according to actual needs.

[0052] The fixture may also include a sensor, which is installed on the frame 10. The sensor monitors the position and characteristics of the workpiece (the size and shape of the workpiece) in real time, and automatically adjusts the clamping force and clamping position between the first clamping end 51 and the second clamping end 61 of the fixture, so that it can be applied to the clamping and positioning of workpieces of different types and sizes, ensuring the accurate positioning of the workpiece, reducing manual intervention, and improving production efficiency. At the same time, sensors and data analysis technology can be integrated to achieve real-time feedback and communication between the fixture and the workpiece, monitor the clamping state of the fixture and the positioning accuracy of the workpiece, adjust the clamping force and position of the fixture in real time, prevent the positioning deviation of the workpiece caused by deformation of the workpiece or insufficient clamping force, and ensure the production quality and production safety of the workpiece.

[0053] By setting up the fixture in a modular way, the applicability and practicality of the fixture can be improved, the equipment investment cost can be reduced, and the versatility and flexibility of the production line can be improved.

[0054] The fixture is suitable for new lightweight materials, such as carbon fiber composite materials, etc. While ensuring the strength and rigidity of the fixture, it can also reduce the weight of the fixture, reduce energy consumption and transportation costs, and improve the energy efficiency and environmental performance of the production line.
