Description

Technical Field

[0001] This utility model relates to the field of flexible gripper structure technology, and in particular to a flexible gripper for clamping precision parts. Background Technology

[0002] Precision parts refer to mechanical components with extremely high requirements for parameters such as dimensional accuracy, shape tolerance, and surface quality. They are typically used in high-tech, aerospace, and medical equipment fields with stringent performance and safety requirements. When gripping precision parts, flexible grippers are usually used. Flexible grippers are end effectors designed specifically for industrial automation, which achieve precise and non-destructive object gripping through flexible materials and pneumatic control technology.

[0003] A search revealed that patent announcement number CN213647601U discloses a flexible clamping device and a robotic arm having this flexible clamping device. The flexible clamping device includes: a mounting support; and at least two clamping mechanisms, all mounted on the mounting support, for jointly clamping a workpiece. Each clamping mechanism includes a flexible finger and a pneumatic source, the pneumatic source being connected to the flexible finger for driving the flexible finger to bend or return to its original position; at least one connecting mechanism, each connecting mechanism being connected to the flexible fingers of every two clamping mechanisms. When some pneumatic sources fail, the remaining pneumatic sources can drive all the flexible fingers to bend or return to their original position, so that the flexible clamping device can continue to work, avoiding the impact on production efficiency caused by disassembling the robotic arm for maintenance.

[0004] However, the existing flexible grippers are connected at the bottom, which makes it inconvenient for the grippers to open and not easy to grasp the items. At the same time, the flexible grippers are not securely installed and are prone to shaking during operation, thus affecting the performance of the flexible grippers. Therefore, there is an urgent need in the market for a flexible gripper for clamping precision parts to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a flexible gripper for clamping precision parts, so as to solve the problems mentioned in the background art, where the lower end of the existing flexible gripper is connected, which makes it inconvenient for the gripper to open and cannot effectively grasp the items. At the same time, the flexible gripper is not firmly installed and is prone to shaking during operation, thus affecting the performance of the flexible gripper.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A flexible gripper for clamping precision parts includes a mounting base, a connecting seat 1 at the upper end of the mounting base, a connecting seat 2 at the lower end of the mounting base, a connecting seat 1 at the upper end of the mounting base, a fixing seat on one side of the connecting seat 2, a connecting end at one end of the fixing seat, connecting brackets at one end of the two opposing inner walls of the connecting end, a flexible gripper at the lower end of the fixing seat, a friction strip at one end of the flexible gripper, a connecting seat 2 at the upper end of the fixing base, and a connecting pipe at the upper end of the connecting seat 2.

[0008] By adopting the above technical solution, the flexible gripper can be easily installed, thereby improving the installation effect of the flexible gripper and preventing it from shaking during use, which would affect the performance of the flexible gripper.

[0009] Furthermore, the connecting seat and the mounting seat are an integral structure. The connecting seat has four fixing screw holes inside, and the four fixing screw holes are symmetrical about the vertical center line of the connecting seat.

[0010] By adopting the above technical solution, the structure between the connecting seat and the mounting seat can be made more robust, and the device can be easily connected and installed through the fixing screw holes provided in the connecting seat.

[0011] Furthermore, three connecting seats are provided, and the three connecting seats are distributed sequentially at the lower end of the mounting base.

[0012] By adopting the above technical solution, the fixed seat can be easily installed through the second connecting seat.

[0013] Furthermore, three connecting seats are provided, the second connecting seat is connected to the connecting pipe, and the connecting pipe is connected to the first connecting seat.

[0014] By adopting the above technical solution, this setting allows for the input of compressed air, which inflates the flexible gripper airbag or contracts the flexible structure, causing the gripper to adhere to the object surface and complete the gripping action. When negative pressure is generated by pumping air out, the gripper returns to its original shape and releases the object.

[0015] Furthermore, the connecting end is provided in two parts. The connecting end and the fixed base are integrated into one structure. The connecting card base and the connecting end are integrated into one structure. The rear end of the second connecting base is provided with a limiting installation end, which is correspondingly provided with the connecting card base.

[0016] By adopting the above technical solution, the structure between the connecting end and the fixed base can be made more robust, and the structure between the connecting bracket and the connecting end can be made more robust. The correspondingly set limiting installation end and connecting bracket can conveniently limit the installation of the fixed base, preventing the fixed base from shaking and thus affecting the installation effect.

[0017] Furthermore, the upper end of the fixing base is provided with a fixing end, and the fixing end is fixedly connected to the connecting base two by fixing screws. There are two fixing screws, one end of which passes through the fixing end and extends into the interior of the connecting base two.

[0018] By adopting the above technical solution, the fixing end and the second connecting seat can be easily installed and fixed by fixing screws, thus facilitating the installation and fixing of the fixing seat and the second connecting seat.

[0019] Furthermore, the friction strip and the flexible gripper are an integral structure, and there are several friction strips arranged sequentially at one end of the flexible gripper. There are three flexible grippers.

[0020] By adopting the above technical solution, the structure between the friction strip and the flexible gripper can be made more robust. The friction strip can improve the friction effect of the flexible gripper, thus making the gripping effect of the flexible gripper better.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) This utility model slides the fixed seat to make the connecting card seat snap-fitted to one end of the limit installation end. This allows the fixed seat and the connecting seat to be snap-fitted together. Then, the fixed seat and the connecting seat can be easily installed and fixed by fixing screws. This can prevent the flexible gripper from shaking during the operation, thus affecting the clamping effect of the flexible gripper.

[0023] (2) This utility model can connect the connecting seat 2 and the connecting seat 1 through the connecting pipe. With this setting, compressed air can be input to make the flexible gripper airbag expand or the flexible structure contract, and the flexible gripper will fit against the surface of the object to complete the gripping action. When the air is pumped out to generate negative pressure, the flexible gripper returns to its original shape and releases the object. This makes it convenient to clamp the object.

[0030] Please see Figures 1-4 This utility model provides an embodiment of a flexible gripper for clamping precision parts, comprising a mounting base 1, a connecting seat 2 at the upper end of the mounting base 1, and three connecting seats 4 arranged sequentially at the lower end of the mounting base 1. A connecting seat 3 is provided at the upper end of the mounting base 1. A fixing base 5 is installed on one side of the connecting seat 4. A connecting end 501 is provided at one end of the fixing base 5, and connecting clamps 502 are provided at the two opposite inner walls of the connecting end 501. A flexible gripper 9 is installed below the fixing base 5. Friction strips 901 are integrally formed with the flexible gripper 9. Several friction strips 901 are arranged sequentially at one end of the flexible gripper 9. There are three flexible grippers 9, with friction strips 901 at one end. The upper part of the fixing base 5... A connecting seat 2 6 is installed, and a connecting pipe 7 is installed above the connecting seat 2 6. Three connecting seats 1 3 are provided.

The connecting seat 1 2 allows for convenient connection and installation of the device. The connecting seat 1 3 allows for air extraction or pressurization. The connecting end 501 and connecting card seat 502 of the fixed seat 5 improve the connection effect between the fixed seat 5 and the connecting seat 2 4. This prevents the fixed seat 5 and the connecting seat 2 4 from shaking when the flexible gripper 9 is working, thus affecting the clamping effect. The friction strip 901 of the flexible gripper 9 improves the clamping effect of the flexible gripper 9. It should be noted that, in order to save space and highlight the innovative elements of this patent, such as the specific working principle and working process of the flexible gripper, it will not be described in detail in this patent.

[0031] See Figure 1 The connecting seat 2 and the mounting seat 1 are an integral structure. The connecting seat 2 has four fixing screw holes 201 inside. The four fixing screw holes 201 are symmetrical about the vertical center line of the connecting seat 2. The device can be easily installed through the connecting seat 2.

[0032] See Figures 1-4 There are two connecting ends 501. The connecting end 501 and the fixed base 5 are integrated. The connecting bracket 502 and the connecting end 501 are integrated. The rear end of the connecting base 4 is provided with a limiting installation end 401, which is correspondingly provided with the connecting bracket 502. The upper end of the fixed base 5 is provided with a fixed end 503. The fixed end 503 and the connecting base 4 are fixedly connected by fixing screws 8. There are two fixing screws 8. One end of the fixing screw 8 passes through the fixing end 503 and extends into the interior of the connecting base 4. The connecting ends 501 and the connecting bracket 502 provided by the fixed base 5 can improve the connection effect between the fixed base 5 and the connecting base 4. The fixing screws 8 can easily install and fix the fixed base 5 and the connecting base 4. This can prevent the fixed base 5 and the connecting base 4 from shaking during the operation of the flexible gripper 9, which would affect the use effect of the flexible gripper 9.

[0033] Working principle: In use, the fixed base 5 is slidably installed so that the connecting card seat 502 is snapped onto one end of the limiting installation end 401. This allows for the snap-fit ​​installation between the fixed base 5 and the connecting base 4. Then, the fixed base 5 and the connecting base 4 are easily fixed together by the fixing screw 8. This prevents the flexible gripper 9 from shaking during operation, which would affect the gripping effect of the flexible gripper 9. Then, the connecting tube 7 connects the connecting base 6 and the connecting base 3. With this setting, compressed air can be input to cause the air bladder of the flexible gripper 9 to expand or the flexible structure to contract. The flexible gripper 9 then adheres to the surface of the object to complete the gripping action. When negative pressure is generated by degassing, the flexible gripper 9 returns to its original shape and releases the object. This allows for convenient clamping of objects.
