This device can grip nuts of different sizes, improving its versatility.

Description

Technical Field

[0001] This utility model belongs to the field of nut processing technology, specifically a positioning and gripping device for nut processing. Background Technology

[0002] Nuts are fasteners used in conjunction with bolts or screws. They are mostly ring-shaped parts with internal threads. By screwing the internal threads into the external threads of the bolt, objects can be tightly connected and fixed. They are made of various materials, including metal and plastic, and are commonly hexagonal, but also round and square. They are widely used in machinery, construction, automobiles and other fields, and play a role in stabilizing parts and preventing loosening. They are common basic parts in industry and daily life.

[0003] In the process of processing nuts, it is often necessary to use a robotic arm to hold the nuts and install them in a predetermined position. When encountering nuts of different sizes, the existing gripping devices cannot be used for nuts of different sizes, which makes the gripping devices not very versatile. At the same time, when nuts are placed randomly in a container, the different orientations of the different sides of the nuts make it difficult for the robotic arm to accurately identify and grip the head of the bolt, resulting in low gripping accuracy and efficiency and increased working time. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a positioning and gripping device for nut processing. It solves the problem that in the process of nut processing, it is often necessary to use a robot to hold the nut and install it in a predetermined position. When encountering nuts of different sizes, the existing gripping device cannot be used for nuts of different sizes, which makes the gripping device not very versatile. At the same time, when the nuts are placed randomly in the container, the different orientations of the different sides of the nuts make it difficult for the robot to accurately identify and grip the head of the bolt, resulting in low gripping accuracy and efficiency and increased working time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning and gripping device for nut processing, comprising a base, a turntable rotatably mounted on the base, two telescopic rods fixedly mounted on the turntable, a connecting plate fixedly mounted at the end of each telescopic rod, a support frame fixedly mounted at the end of the connecting plate, a second telescopic rod fixedly mounted on the support frame, a toothed plate mounted at the end of the second telescopic rod penetrating the support frame, a rotating shaft rotatably mounted inside the support frame, a gear mounted on the rotating shaft, a sliding rod fixedly mounted inside the support frame, two toothed blocks slidably mounted on the sliding rod, two gears meshing with two toothed blocks respectively, a pressure strip fixedly mounted at the bottom of each toothed block, and a fixing frame fixedly mounted on the base.

[0006] As a further embodiment of this utility model: the base has an inner cavity, and a motor is installed in the inner cavity.

[0007] As a further embodiment of this utility model: a rotating rod is rotatably connected to the output shaft of the motor, and one end of the rotating rod passes through the base and is connected to the turntable.

[0008] As a further embodiment of this utility model: the base has two limiting grooves, which correspond to two pressure strips, and the base has a positioning groove.

[0009] As a further embodiment of this utility model: a positioning column is fixedly installed in the positioning groove, and a sliding groove is provided on the fixing frame.

[0010] As a further embodiment of this utility model: an electric push rod is fixedly installed inside the slide groove, and a push plate is installed at the end of the electric push rod, with the push plate slidably installed on the slide groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This positioning and gripping device for nut processing consists of a telescopic rod, a pressure bar, a support frame, and gears. During operation, the operator activates two telescopic rods, which move the support frame downwards. This movement causes the components mounted on the support frame to move synchronously until the two pressure bars enter the limiting groove. Then, the operator opens the second telescopic rod, which moves the toothed plate upwards. Since the toothed plate meshes with two gears, its movement causes the gears to rotate. Since the gears mesh with two toothed blocks, their rotation causes the two toothed blocks to move towards each other. This movement causes the pressure bar mounted at the bottom to move until it presses against the edge of the nut. Then, the telescopic rod moves the support frame and pressure bar upwards until the pressure bar grips the nut out of the positioning groove. This device can grip nuts of different sizes, improving its versatility.

[0013] 2. This positioning and gripping device for nut processing, consisting of an electric push rod, a motor, a turntable, and a rotating rod, allows the operator to place the nut to be processed in the slide groove after adjusting its position. The electric push rod then uses a push plate to push the nut from the slide groove into the positioning slot. Once the clamping bar has gripped the nut, the motor is activated, and its output shaft drives the rotating rod and turntable to rotate until the gripped nut is moved to the appropriate position, facilitating subsequent nut processing and improving clamping accuracy.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a positioning and gripping device for nut processing, including a base 1, two limiting grooves 14 are provided on the base 1, the two limiting grooves 14 correspond to two pressure strips 13, and a positioning groove 17 is provided on the base 1.

[0021] A positioning column 18 is fixedly installed in the positioning groove 17, and a sliding groove 22 is provided on the fixing frame 6.

[0022] An electric push rod 15 is fixedly installed inside the slide groove 22. A push plate 16 is installed at the end of the electric push rod 15. The push plate 16 is slidably installed on the slide groove 22. Because of the electric push rod 15, after the nut to be processed is adjusted to the correct position and placed in the slide groove 22, the electric push rod 15 is opened. The electric push rod 15 works to push the nut that has been adjusted to the correct position in the slide groove 22 into the positioning groove 17 using the push plate 16, which improves the accuracy of subsequent gripping work.

[0023] The base 1 has an inner cavity 19, in which a motor 20 is installed. A rotating rod 21 is rotatably connected to the output shaft of the motor 20. One end of the rotating rod 21 passes through the base 1 and is connected to the turntable 2. Because the motor 20 is installed, when the pressure bar 13 grabs the nut, the output shaft of the motor 20 can drive the rotating rod 21 and the turntable 2 to rotate until the grabbed nut is moved to a suitable position, which facilitates the subsequent nut processing work and improves work efficiency.

[0024] A turntable 2 is rotatably mounted on the base 1, and two telescopic rods 3 are fixedly mounted on the turntable 2. Because of the telescopic rods 3, the height of the support frame 5 can be freely adjusted through the telescopic rods 3, which facilitates the gripping work.

[0025] A connecting plate 4 is fixedly installed at the end of the telescopic rod 3, and a support frame 5 is fixedly installed at the end of the connecting plate 4. A telescopic rod 7 is fixedly installed on the support frame 5. Because of the installation of the telescopic rod 7, the operation of the telescopic rod 7 drives the toothed plate 8 to move upward. The movement of the toothed plate 8 will drive the two gears 10 to rotate. The rotation of the gears 10 will drive the two toothed blocks 12 to move towards each other. The movement of the toothed blocks 12 will drive the pressure strip 13 installed at the bottom to move until the pressure strip 13 presses the edge of the nut. Then, the telescopic rod 3 drives the support frame 5 and the pressure strip 13 to move upward until the pressure strip 13 grabs the nut out of the positioning groove 17. It can grab nuts of different sizes, improving the versatility of the gripping device.

[0026] The end of the telescopic rod 7 passes through the support frame 5 and is equipped with a toothed plate 8. A rotating shaft 9 is rotatably installed inside the support frame 5. A gear 10 is installed on the rotating shaft 9. A sliding rod 11 is fixedly installed inside the support frame 5. Two toothed blocks 12 are slidably installed on the sliding rod 11. The two gears 10 mesh with the two toothed blocks 12 respectively. A pressure strip 13 is fixedly installed at the bottom of the toothed blocks 12. A fixing frame 6 is fixedly installed on the base 1.

[0027] The working principle of this utility model is as follows: During operation, the worker adjusts the position of the nut to be processed and places it in the slide groove 22. Then, the electric push rod 15 is turned on. The electric push rod 15 uses the push plate 16 to push the nut in the slide groove 22 into the positioning groove 17. Then, the two telescopic rods 1-3 are activated. The two telescopic rods 1-3 drive the support frame 5 to move downward. The movement of the support frame 5 drives the components installed on it to move synchronously until the two pressure strips 13 enter the limiting groove 14. Then, the telescopic rod 2-7 is turned on. The telescopic rod 2-7 drives the toothed plate 8 to move upward. Because the toothed plate 8... The gear plate 8 moves with the two gears 10, so the movement of the gear plate 8 will drive the two gears 10 to rotate. Since the gear 10 meshes with the two tooth blocks 12, the rotation of the gear 10 will drive the two tooth blocks 12 to move towards each other. The movement of the tooth blocks 12 will drive the pressure strip 13 installed at the bottom to move until the pressure strip 13 presses the edge of the nut. Then, the support frame 5 and the pressure strip 13 will move upward through the telescopic rod 3 until the pressure strip 13 grabs the nut out of the positioning groove 17. Then, the motor 20 will be turned on, and the output shaft of the motor 20 will drive the rotating rod 21 and the turntable 2 to rotate until the nut to be grabbed is moved to the appropriate position.
