[0002] As my country accelerates the upgrading of its industrial intelligent manufacturing industry, the integration of industrial robots and other automation equipment as core competitiveness has shown an explosive growth trend. Factories will gradually adopt robots to replace manual labor. Robots are machine devices that automatically perform work. Robots are assembled from multiple accessories. The robot clamping fixture commonly used in existing devices has the main function of realizing the clamping task of the end of the robot arm directly acting on the work object. This device can have the functions of clamping, transporting, and placing the workpiece to a certain position. According to the specific application requirements and working environment, the design and structure of the robot clamping fixture may be different. Although the device is fast and convenient to use, it still has certain defects, that is, when clamping the workpiece, the size of the clamping plate is fixed. If the workpiece size is large, the clamping plate cannot stably play the clamping role, which will cause the work process to be blocked and affect the work efficiency; for this reason, we design a robot fast clamping fixture to solve the above technical problems.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0017] See also Figure 1-3 In the embodiment of the utility model, a robot fast clamping fixture includes a clamping frame 2 connected to a robot arm 1. The clamping frame 2 is a "U"-shaped structure. The clamping frame 2 is formed integrally by an upper side plate, a vertical plate and a lower side plate. A hydraulic cylinder 3 is fixedly arranged at the bottom of the upper side plate. The output end of the hydraulic cylinder 3 is vertically downward and connected to a movable clamping plate 4. The left side of the movable clamping plate 4 is slidably connected to the outer wall of the vertical plate. The top of the right side of the movable clamping plate 4 is rotatably connected to a first extension plate 8 through a first hinge. The right side of the movable clamping plate 4 is symmetrically provided with a receiving slot 5 in the front and rear directions. A clamping rod 7 adapted to the receiving slot 5 is slidably arranged in the receiving slot 5. The length of the clamping rod 7 is equal to the length of the storage slot 5. A connecting groove 12 corresponding to the storage slot 5 is provided on the top of the movable clamping plate 4. The connecting groove 12 is connected to the inside of the corresponding storage slot 5. A connecting rod adapted to it is slidably provided in the connecting groove 12. One end of the connecting rod extends into the storage slot 5 and is fixedly connected to the left end of the outside of the corresponding clamping rod 7. The other end of the connecting rod is fixedly connected to a push button 6. The push button 6 is slidably connected to the top surface of the movable clamping plate 4. A clamping hole 10 for the clamping rod 7 to be embedded is provided on one side of the first extension plate 8 close to the right side surface of the movable clamping plate 4. The length of the clamping hole 10 is less than the length of the storage slot 5.
[0018] A magnet 9 is embedded in the top surface of the first extension plate 8 at one end away from the hinge, and an iron bar 11 matching the magnet 9 is embedded in the top surface of the movable clamping plate 4; Figure 3As shown, when the first extension plate 8 is not in use, the first extension plate 8 can be flipped to the top of the movable clamping plate 4, and the magnet 9 is fitted with the iron bar 11. The adsorption force of the magnet 9 on the iron bar 11 is used to ensure that the position of the first extension plate 8 is fixed to avoid affecting the normal use of the device. When the first extension plate 8 is needed, it is only necessary to turn the first extension plate 8 with a little force to separate the magnet 9 from the iron bar 11 until the left side of the first extension plate 8 is fitted with the right side of the movable clamping plate 4. At this time, the staff can push the push button 6 to the right, drive the corresponding clamping rod 7 to move to the right through the connecting rod, and embed the clamping rod 7 into the corresponding clamping hole 10, so that the position of the first extension plate 8 is fixed at this time, which is convenient for the first extension plate 8 to play a role in clamping the workpiece. That is, the device can increase the area of the clamping plate, that is, it also has a good and stable clamping effect on larger workpieces, has high applicability, and is easy to operate.
[0019] Two parallel dovetail grooves 14 are provided on the right side surface of the vertical plate in the vertical direction, and a clamping block 13 adapted to the dovetail groove 14 is provided on the left side of the movable clamping plate 4; the stability of the upward and downward movement of the movable clamping plate 4 is ensured by the sliding cooperation connection between the clamping block 13 and the dovetail groove 14.
[0020] The bottom of the right side of the lower side plate is rotatably connected to the second extension plate 15 through a second hinge. The matching connection structure design of the lower side plate and the second extension plate 15 is the same as the matching connection design of the movable clamping plate 4 and the first extension plate 8. Figure 1 and Figure 2 As shown, no further details are given here. Similarly, the second extension plate 15 is used together with the first extension plate 8 to improve the clamping ability and applicability of the device, which is worthy of promotion.
