Description

Technical Field

[0001] The present application relates to the technical field of mechanical clamps, and in particular to a large-opening rotating clamp. Background Art

[0002] Grippers play an important role in the field of industrial automation, especially in situations where large or special-shaped materials need to be clamped and moved quickly and accurately. However, there are still some problems and shortcomings in the design of the grippers currently on the market, which affect their performance and application.

[0003] First, traditional grippers usually use complex mechanical structures and transmission systems, which makes them heavy and inflexible. This not only affects the rotation speed of the gripper, but also limits its application in large-scale clamping and high-speed rotation scenarios. Secondly, existing grippers often lack sufficient adaptive capabilities and cannot be intelligently adjusted according to the size and shape of different materials. This means that in actual applications, the opening and posture of the gripper need to be manually adjusted according to different materials, which increases the complexity of operation and production costs.

[0004] In summary, existing grippers have many design drawbacks, such as complex mechanical structure, poor adaptability, insufficient protection of materials during the clamping process, etc. These problems limit their performance and scope of application in practical applications, and need to be solved through design innovation.

After being processed by the controller, the driving member 13 is controlled to rotate, and the driving member 13 drives the clamp body 2 to move, so as to achieve the clamping of different materials.

[0039] Embodiment 2

[0040] The difference between this embodiment and the first embodiment is that, referring to Figure 2 and Figure 3A support plate 4 is provided on the side of the jaw body 2 away from the end plate 1. The support plate 4 is rotatably provided on the jaw body 2. A placement slot 21 is provided on the side of the jaw body 2 away from the other jaw body 2. A control component 5 is provided on the end plate 1. The control component 5 and the support plate 4 are connected to adjust the position of the support plate 4. In the initial state, the support plate 4 is in a retracted state in the placement slot 21 so that the jaw body 2 can clamp the material. After the material is clamped and lifted, the control component 5 drives the support plate 4 to rotate to the side of the jaw body 2 close to the other jaw body 2. At this time, the support plate 4 rotates to the bottom of the material to lift the material. In this embodiment, the support plate 4 is in a vertical state relative to the jaw body 2 when lifting the material. The material is supported by the support plate 4 to reduce the phenomenon of the material falling during the movement.

[0041] Reference Figure 3 and Figure 4 The clamp body 2 is provided with a mounting groove 22, the control assembly 5 comprises a control member 51, a control rod 52, a transmission rod 53 and a transmission gear set 54, the transmission rod 53 is rotatably arranged in the mounting groove 22, the rotation axis of the support plate 4 extends into the mounting groove 22, the control member 51 is arranged on the end plate 1, the control rod 52 is rotatably arranged on the end plate 1, the control rod 52 is connected to the output end of the control member 51, and the transmission gear set 54 is used to connect the transmission rod 53 and the control member 52. The control member 51 drives the control rod 52 to rotate, the control rod 52 drives the transmission rod 53 to rotate through the transmission gear set 54, and at the same time, the transmission rod 53 drives the support plate 4 to rotate through the transmission gear set 54, so as to adjust the position of the support plate 4.

[0042] Reference Figure 4 and Figure 5A slot 23 is provided through the clamp body 2, and the slot 23 is connected to the mounting slot 22. The transmission gear set 54 includes a first gear 541, a second gear 542, a first worm 543, a first worm wheel 544, a second worm 545 and a second worm wheel 546. The first gear 541 is rotatably arranged in the mounting slot 22, the control rod 52 is arranged through the slot 23 and penetrates the first gear 541, the control rod 52 is slidably arranged in the first gear 541, the first worm wheel 544 and the second worm wheel 545 are coaxially arranged at both ends of the transmission rod 53, the first worm 543 and the second gear 542 are coaxially arranged, the second gear 542 is meshed with the first gear 541, the second worm 545 is meshed with the second worm wheel 546, and the second worm wheel 546 is coaxially arranged with the rotating shaft of the support plate 4. The control member 51 drives the control rod 52 to rotate, and the control rod 52 drives the second gear 542 to rotate through the first gear 541. The second gear 542 drives the support plate 4 to rotate through the first worm 543, the first worm wheel 544, the transmission rod 53, the second worm 545 and the second worm wheel 546 in turn, and adjusts the position of the support plate 4. At the same time, the worm wheel and the worm have self-locking properties, and when the support plate 4 lifts the material, the rotation deviation of the support plate 4 is reduced. At the same time, the first gear 541 is slidably arranged outside the control rod 52. When the clamp body 2 moves, the first gear 541 can move relative to the control rod 52 while moving with the clamp body 2, so that when the clamp body 2 moves to any position, the position of the support plate 4 can be adjusted by the control member 51, and the control rod 52 can be prevented from interfering with the movement of the clamp body 2.

[0043] Reference Figure 4 and Figure 5 An adjusting rod 6 is rotatably arranged in the installation groove 22, and the rotation axis of the adjusting rod 6 is arranged along a direction perpendicular to the movement of the clamp body 2. An intermediate piece 7 is arranged in the installation groove 22, and the adjusting rod 6 is connected to the transmission rod 53 through the intermediate piece 7. The intermediate piece 7 includes a third worm 71, a third worm wheel 72 and a bevel gear set 73. The third worm 71 is coaxially arranged outside the transmission rod 53, and the third worm wheel 72 is meshed with the third worm 71. One bevel gear of the bevel gear set 73 is coaxially connected with the rotation axis of the adjusting rod 6, and the other bevel gear is meshed with the third worm wheel 72, and the two bevel gears are meshed.

[0044] When the jaw body 2 clamps the material, the side of the adjusting rod 6 abuts against the side of the material. When the control member 51 drives the support plate 4 to rotate through the transmission rod 53, the adjusting rod 6 is driven to rotate through the third worm 71, the third worm wheel 72 and the bevel gear set 73. The adjusting rod 6 rotates to drive the material to move in the direction toward the end plate 1, so that the support plate 4 rotates to abut against the bottom of the material to support the material. At the same time, the position of the material is adjusted by the adjusting rod 6, so that the jaw body 2 completely clamps the material and improves the stability of the material clamping. In addition, the adjusting rod 6 and the middle member 7 can be set to multiple groups, and the multiple groups of adjusting rods 6 are arranged at intervals on the jaw body 2. By setting multiple groups of adjusting rods 6, the adjusting rod 6 can adjust the material at any position in the jaw body 2 to improve the adjustment efficiency.

[0045] Reference Figure 3 and Figure 6 An auxiliary plate 8 is provided on the side of the clamp body 2 close to the adjustment rod 6. The auxiliary plate 8 is slidably provided on the clamp body 2 in the direction toward the other clamp body 2. An auxiliary groove 81 is provided on the auxiliary plate 8. The auxiliary plate 8 is sleeved on the outside of the adjustment rod 6 through the auxiliary groove 81. An elastic member 82 is provided on the auxiliary plate 8. The elastic member 82 is provided on the side of the auxiliary plate 8 close to the mounting groove 22. The elastic member 82 can be set as a spring. The spring is provided along the sliding direction of the auxiliary plate 8. One end of the spring is connected to the inner wall of the mounting groove 22, and the other end is connected to the auxiliary plate 8. The elastic member 82 is used to drive the auxiliary plate 8 to slide in the direction toward the outside of the mounting groove 22. A linkage assembly 9 is provided in the mounting groove 22. The linkage assembly 9 is used to connect the auxiliary plate 8 and the transmission rod 53. In the initial state, the clamping plate clamps the material through the auxiliary plate 8. While the support plate 4 rotates, the transmission rod 53 drives the auxiliary plate 8 to move into the installation groove 22 through the linkage assembly 9, and the auxiliary plate 8 is separated from the material. At the same time, the side of the adjusting rod 6 abuts against the material so that the adjusting rod 6 can adjust the position of the material. After the position of the material is adjusted, the auxiliary plate 8 moves to the initial position again under the action of the elastic member 82 to clamp the material, and at the same time, the support plate 4 completely supports the material.

[0046] Reference Figure 6 and Figure 7The linkage assembly 9 includes a linkage column 91, a linkage rod 92 and a linkage plate 93. The linkage plate 93 is connected to the auxiliary plate 8. The linkage rod 92 is slidably arranged in the installation groove 22, and the sliding direction of the linkage rod 92 is perpendicular to the sliding direction of the auxiliary plate 8. A guide rod 921 is arranged on the linkage rod 92, and a guide groove 931 is opened on the linkage plate 93. The end of the guide groove 931 is inclined along the sliding direction of the auxiliary plate 8. The guide rod 921 is slidably arranged in the guide groove 931. The linkage column 91 and the transmission rod 53 are coaxially arranged. A linkage groove is opened on the side of the linkage column 91. The end of the linkage rod 92 is slidably arranged in the linkage groove. The linkage groove includes a guide portion 911 and a reset portion 912. The guide portion 911 is spirally arranged around the linkage column 91, and the reset portion 912 is arranged along the axial direction of the linkage column 91. The end of the reset portion 912 is connected to the guide portion 911.

[0047] The transmission rod 53 drives the linkage column 91 to rotate, and the rotation of the linkage column 91 drives different positions in the guide part 911 to cooperate with the linkage rod 92, and at the same time drives the linkage rod 92 to slide in the installation groove 22, and at the same time the linkage rod 92 drives the guide rod 921 to cooperate with different positions in the guide groove 931, and then drives the auxiliary plate 8 to move, and adjusts the position of the auxiliary plate 8. After the adjustment rod 6 adjusts the position of the material, the linkage column 91 continues to rotate, driving the linkage rod 92 to move to the reset part 912, and the auxiliary plate 8 returns to the initial position under the action of the elastic member 82. At the same time, the linkage rod 92 moves to the initial position through the reset part 912, so as to adjust the position of the auxiliary plate 8 again. Two groups of guide parts 911 and reset parts 912 are arranged along the axis direction of the linkage column 91. So that when the transmission rod 53 rotates in the reverse direction to drive the support plate 4 to the placement groove 21, the linkage rod 92 can move in the reverse direction accordingly, reducing the phenomenon that the linkage rod 92 interferes with the reverse rotation of the transmission rod 53.

[0048] The implementation principle of this application is: the driving member 13 drives the lead screw 12 to rotate through the transmission belt 14, and the lead screw 12 rotates to drive the clamp body 2 to hold the material, and at the same time, the control member 51 drives the support plate 4 to rotate through the transmission rod 53 until the bottom of the support plate 4 abuts against the material, so that the material is lifted by the support plate 4 after clamping, and the stability of the clamp body 2 clamping the material is improved. At the same time, when the end needs to be rotated, the rotating wheel 3 is transferred to realize the rotation of the entire clamp body 2, so as to clamp the material at different positions. Then the applicability and application range of the clamp are improved.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
