Description

Technical Field

[0001] This utility model relates to the field of workpiece gripping technology, specifically to a robotic gripping tool. Background Technology

[0002] Automotive frame tubes specifically refer to the tubular materials used in manufacturing the load-bearing frame (chassis) of automobiles. They are mainly used in vehicles with non-load-bearing bodies. The frame tube is generally a trapezoidal frame, consisting of two main longitudinal beams running through the front of the vehicle and several crossbeams, resembling a ladder. The main longitudinal beams and crossbeams are usually rectangular or square cross-section beams made of high-strength steel tubing because it has better bending strength than round tubing.

[0003] Currently, the gripping of automotive chassis tubes is generally done using robotic gripping fixtures, which employ a long octagonal tube fixed at both ends with pneumatic clamping to grip the product. This type of fixture lacks flexibility and has a small adjustable range. Since different automotive chassis tubes have different size requirements, different fixtures need to be designed for different chassis tubes, which greatly increases costs. When changing products, matching fixtures need to be replaced, increasing changeover time and causing waiting waste. At the same time, the large number of fixtures places a great burden on fixture management. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figure 1 , Figure 2 and Figure 3 A robotic gripper for gripping automotive frame tubes includes a frame 1, a crossbar 2, a guide rail fixing rod 3, a guide rail 4, a sensor 1 5, a sensor 2 6, a guide rail limiting block 7, an adapter block 8, a workpiece clamping component 9, a cylinder 10, a cylinder base 11, a connecting plate 12, a telescopic rod 13, a telescopic rod fixing block 14, a guide block 15, a locking block 16, and a sensor 3 17.

[0020] One side of the crossbar 2 is fitted with a guide rail fixing rod 3 via bolts or pins. A guide rail 4 is detachably mounted on the guide rail fixing rod 3 via bolts or pins. A guide block 15 is slidably connected to the outside of the guide rail 4. A locking block 16 is connected to the bottom of the guide block 15 and is detachably connected to the frame 1 via bolts or pins. It should be noted that several mounting holes are equally spaced on both the frame 1 and the crossbar 2 to facilitate the installation of various structures (such as the guide rail fixing block 3 and sensor 5 mounted on the crossbar 2) and to allow for quick repositioning of various structures as needed. In this application, both the crossbar 2 and the support rod of the frame are made of octagonal tubing, with mounting holes on all eight sides to facilitate the installation and adjustment of various structures.

[0021] Reference Figure 1 A cylinder base 11 is detachably mounted on the top of the frame 1 by bolts or pins. Two sets of cylinders 10 are mounted on the top of the cylinder base 11. The output ends of the two sets of cylinders 10 are detachably connected to the connecting plates 12 located on both sides of the cylinder base 11. Sensors 6 are detachably mounted on the ends of the two connecting plates 12. Sensors 5, corresponding to the positions of sensors 6, are detachably mounted on both ends of the crossbar 2. Sensors 5 can contact sensors 6.

[0022] Reference Figure 1 A telescopic rod fixing block 14 is detachably installed on the top of the frame 1 by bolts or pins. A telescopic rod 13 is installed on the telescopic rod fixing block 14. The two ends of the telescopic rod 13 are detachably connected to the connecting plates 12 on both sides. The two sets of connecting plates 12 are arranged in parallel and perpendicular to the crossbar 2. The telescopic rod 13 is arranged in parallel with the crossbar 2. The telescopic rod 13 can drive the two sets of connecting plates 12 to slide along the guide rail 4 on the crossbar 2.

[0023] Reference Figure 1 A transition block 8 is detachably installed at the bottom of the two connecting plates 12 by bolts or pins. A workpiece clamping part 9 is detachably installed at the bottom of the transition block 8 by bolts or pins. One side of the transition block 8 is also connected to a slider that is slidably installed on the guide rail 4. It should be noted that guide rail limit blocks 7 are also installed at both ends of the guide rail 4. The guide rail limit blocks 7 are used to limit the position of the connecting plates 12 when adjusting.

[0024] Reference Figure 2 The workpiece clamping component 9 includes a bracket 91 and a second cylinder 92 mounted on the bracket. The output end of the second cylinder 92 is connected to the rear end of the clamping component 93. The clamping component 93 is stepped in shape, with its front end located directly below the bracket 91. The middle position of the clamping component 93 is movably connected to the second cylinder 92 located directly above it via a connecting rod 94. Therefore, the second cylinder 92 can push the rear end of the clamping component 93 downward. At this time, the middle of the clamping component 93 remains stationary, while the front end tilts upward, which is exactly against the bracket 91. At this time, the workpiece can be clamped by using the front end of the clamping component 93 and the bracket 91. The third sensor 95 is located inside the bracket 91 and is used to detect the position of the workpiece.

[0025] The specific operating principle of this application is as follows: This application involves adjusting the position of sensor 5 on crossbar 2 according to different product sizes to achieve the purpose of gripping products of different sizes. Before the tooling grips the product, cylinder 10 is not working and the pneumatic clamp is in a retracted posture (e.g., ...). Figure 3When the tooling moves to the gripping position with the robot arm, the cylinder 10 works and the workpiece clamping part 9 opens. When the sensor 6 on the workpiece clamping part 9 contacts the sensor 5 on the crossbar 2, the cylinder 10 stops working and begins to grip the product. If it is necessary to grip products of different sizes, simply adjust the position of the sensor 5 on the crossbar 2.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
