Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a robot clamping fixture. Background Art

[0002] A clamping jig is a device used to clamp, fix and position a workpiece. It is commonly used in automated production lines, machining processes and various industrial applications. These jigs can ensure the stability and accuracy of the workpiece during machining, while improving production efficiency and safety. In robot operation, the clamping jig is used in conjunction with the robot system to achieve automated workpiece clamping, positioning and placement. Existing machine clamping jigs only have a simple left and right tightening clamping method, and the clamping method is single. It is impossible to select a reasonable clamping method according to the actual machining scenario, resulting in the need to frequently replace the fixture structure. Therefore, the present invention proposes a robot clamping jig to solve the problems mentioned in the above background technology. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Referring to Figure 1-4 , a robot clamping fixture, including a clamping robot body 1, on which a robotic arm base 2 is installed. A fixed shaft is fixed at the front end of the robotic arm base 2, and a clamping plate 4 is rotatably connected around the fixed shaft. A motor 10 is fixedly installed on the lower side of the clamping plate 4. The output shaft of the motor 10 is connected to a rotating plate 5 located on the upper side of the clamping plate 4. Both ends of the rotating plate 5 are rotatably connected to connecting arc plates 6. The outer ends of the two connecting arc plates 6 are respectively rotatably connected to the two side sliders 7. The output shaft of the motor 10 tightens or unfolds the two side clamping blocks through the two side connecting arc plates 6;

[0021] Furthermore, there are two upper and lower positioning sockets 3 provided between the clamping plate 4 and the rear robotic arm base 2. Slots corresponding to the positioning sockets 3 are opened on both the upper and lower sides of the clamping plate 4 and the robotic arm base 2, and the positioning sockets 3 are in a "C" shape. When the clamping plate 4 on the front side of the robotic arm base 2 rotates by 90 degrees, the two side positioning sockets 3 can still be inserted into the corresponding slots. When switching the clamping method of the clamping mechanism, rotate the clamping plate 4 by 90 degrees, and the clamping plate 4 and the rear robotic arm base 2 are in a vertical relationship. At this time, the upper and lower clamping is different from the traditional left and right clamping method, which is suitable for more processing scenarios;

[0022] Even further, there are two left and right sliders 7 provided on the front side of the clamping plate 4. The sliders 7 slide left and right on the clamping plate 4. A first clamping block 8 is fixed to the front side of one slider 7, and two second clamping blocks 9 are provided on the front side of the other slider 7. Both of the two second clamping blocks 9 are rotatably connected to the corresponding slider 7. Straight gears 14 are fixed to the outer ends of the two second clamping blocks 9. A rack block 11 is provided between the two straight gears 14. The rack block 11 slides horizontally on the outside of the corresponding slider 7, and the two second clamping blocks 9 are driven to unfold or overlap through the middle straight gear 14;

[0023] Furthermore, a slide seat 12 that slides inside and outside is provided in the clamping plate 4, the inner end of the rack block 11 slides in the slide seat 12, and springs 13 are provided between the two sides of the rack block 11 and the corresponding slider 7, a bevel column 15 is fixed to the front end of the fixed axis of the robot arm seat 2, and a resisting rod 16 corresponding to the bevel column 15 is fixed to the inner side of the slide seat 12. As the slide seat 12 rotates, the resisting rod 16 changes position on the bevel column 15, and when the clamping plate 4 on the front side of the robot arm seat 2 rotates vertically The resistance rod 16 contacts the inclined column 15 and is squeezed outward, so that the slide seat 12 connected to the resistance rod 16 moves outward, and then links the rack block 11 structure therein, so that the two clamping blocks 9 turned to the lower side are unfolded, forming a shape that is more suitable for upper and lower clamping. When the clamping plate 4 on the front side of the robot arm seat 2 is flattened, it is squeezed by the springs 13 on both sides and the slide seat 12 returns to its original position. During this period, the switching of the angle of the clamping plate 4 is restricted by the upper and lower positioning sockets 3 and the corresponding sockets.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
