Description

Technical Field

[0001] The utility model relates to the technical field of automated production and processing, in particular to a double-position inner support jaw mechanism. Background Art

[0002] During the production and processing process, automated fixtures are generally used to clamp and move products. For cavity-type parts, common fixtures such as cylinder jaws, flexible jaws, and silicone airbags cannot effectively clamp and move such parts, and inner support jaws are often required for corresponding clamping work. In order to improve the material picking efficiency of parts and products, multiple groups of inner support jaws are generally set to pick up and place materials synchronously. In the prior art, multiple groups of multi-axis moving mechanisms are generally used to drive the displacement of different inner support jaws respectively, or multiple groups of inner support jaws are arranged on a group of multi-axis moving mechanisms. However, the above setting methods will occupy too much setting space due to multiple groups of multi-axis moving mechanisms, or the overall structure will be large due to arranging multiple groups of inner support jaws on the same group of multi-axis moving mechanisms, occupying too much space, and it is also easy to affect the movement or work of other mechanisms, presenting great inconvenience and disadvantages.

[0003] Therefore, there are defects in the prior art and improvements are needed. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a double-position inner support jaw mechanism.

[0005] The technical solution of the utility model is as follows: A double-position inner support jaw mechanism is provided, including: a support plate, a first lifting cylinder arranged on one side surface of the support plate, a second lifting cylinder arranged on the other side surface of the support plate, and pneumatic jaws respectively arranged on the first lifting cylinder and the second lifting cylinder, and the first lifting cylinder and the second lifting cylinder respectively drive the pneumatic jaws to move up and down reciprocally.

[0006] Further, the pneumatic jaw includes: a jaw cylinder, and a jaw arranged on the output end of the jaw cylinder, and the outer side of the jaw is a tightening surface in contact with the material.

[0007] Further, a limiting block is arranged on the tightening surface of the jaw.

[0008] Further, jaw brackets are respectively arranged on the first lifting cylinder and the second lifting cylinder, and the pneumatic jaws are arranged on the jaw brackets.

[0009] Further, the jaw bracket is L-shaped.

[0010] Further, the support plate is connected with a manipulator.

[0011] With the above solution, the utility model sets the first lifting cylinder and the second lifting cylinder on both side surfaces of the support plate respectively, so that the pneumatic grippers on both sides can be as close as possible to the central axis of the support plate, thereby effectively reducing the space occupied by the overall mechanism, avoiding interference or collision with other mechanisms during the movement, and effectively improving the overall safety. At the same time, by making the pneumatic grippers as close as possible to the central axis of the support plate, the center of gravity of the overall mechanism is made more stable, improving the stability during the picking and moving of parts. Brief Description of the Drawings

[0012] Figure 1 It is a structural schematic diagram of the utility model. Detailed Embodiments

[0013] The following will describe the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0014] Please refer to Figure 1 , the utility model provides a double-position inner support gripper mechanism, including: a support plate 1, a first lifting cylinder 21 disposed on one side surface of the support plate 1, a second lifting cylinder 22 disposed on the other side surface of the support plate 1, and pneumatic grippers 3 respectively disposed on the first lifting cylinder 21 and the second lifting cylinder 22. The first lifting cylinder 21 and the second lifting cylinder 22 respectively drive the pneumatic grippers 3 to move up and down reciprocally. By setting the first lifting cylinder 21 and the second lifting cylinder 22 on both side surfaces of the support plate 1 respectively, the pneumatic grippers 3 on both sides can be as close as possible to the central axis of the support plate 1, thereby effectively reducing the space occupied by the overall mechanism, avoiding interference or collision with other mechanisms during the movement, and effectively improving the overall safety. At the same time, by making the pneumatic grippers 3 as close as possible to the central axis of the support plate 1, the center of gravity of the overall mechanism is made more stable, improving the stability during the picking and moving of parts.

[0015] In some embodiments, the pneumatic gripper 3 includes: a gripper cylinder 31, and a gripper 32 disposed on the output end of the gripper cylinder 31. The outer side of the gripper 32 is a tightening surface in contact with the material. When the gripper cylinder 31 is started, the output claw of the gripper cylinder 31 moves outward, thereby pushing the gripper 32 outward, so as to perform an inner support type fixation on the part from the hole or groove of the cavity-type part, facilitating the picking of the part and moving it to the corresponding position for placement. For cavity-type parts, during their production and processing, such products are often placed in the cavity of the fixture, so it is difficult to effectively pick them up through a conventional gripper mechanism. By adopting an inner support type clamping method, the part is internally supported and fixed from the cavity of the part, so as to take out the part from the cavity of the fixture and then move it to the fixture in the next process or on the transportation line, ensuring the picking and moving of the part.

[0016] In some embodiments, a limiting block 33 is provided on the tightening surface of the clamping jaw 32. When the clamping jaw 32 of the pneumatic clamping jaw 3 extends into the cavity of the part, the limiting block 33 contacts the top surface of the part, thereby limiting the part and preventing the clamping jaw 32 from extending excessively into the part, which may cause the part to be unable to be effectively aligned with the fixture cavity at the placement location during subsequent material placement, thus affecting the placement effect.

[0017] In some embodiments, clamping jaw brackets 23 are respectively provided on the first lifting cylinder 21 and the second lifting cylinder 22, and the pneumatic clamping jaw 3 is arranged on the clamping jaw bracket 23. In some embodiments, the clamping jaw bracket 23 is L-shaped. By using the L-shaped clamping jaw bracket 23, the pneumatic clamping jaw 3 can be arranged on the other two sides of the support plate 1, so that the pneumatic clamping jaw 3 can be arranged as close as possible to the central axis of the support plate 1, making the overall center of gravity more stable and ensuring that the overall mechanism does not shake during the operation of the two pneumatic clamping jaws 3, thereby ensuring the stability and safety of picking up and moving the parts.

[0018] In some embodiments, the support plate 1 is connected to a manipulator 4, and the manipulator 4 moves the support plate 1, thereby moving the pneumatic clamping jaw 3 to the corresponding pick-and-place position to complete the picking and transfer of the parts.

[0019] Specifically, the inner support clamping jaw mechanism provided by the present invention can simultaneously realize the pick-and-place of two groups of parts, or realize the replacement of processed parts and unprocessed parts.

[0020] When picking and placing two groups of parts simultaneously, first, the manipulator 4 moves the support plate 1 to the picking position. The first lifting cylinder 21 moves the pneumatic clamping jaw 3 downward, and the pneumatic clamping jaw 3 picks up the material from the fixture, and then the first lifting cylinder 21 is reset. Then the second lifting cylinder 22 moves the pneumatic clamping jaw 3 downward, the pneumatic clamping jaw 3 picks up the material from the fixture, and then the second lifting cylinder 22 is reset. Then the manipulator 4 moves the support plate 1 to the placing position. The first lifting cylinder 21 moves the pneumatic clamping jaw 3 downward, so that the part picked up by the pneumatic clamping jaw 3 is embedded in the fixture cavity at the placing position, and the pneumatic clamping jaw 3 releases the material, causing the material to separate from the pneumatic clamping jaw 3. Then the first lifting cylinder 21 resets the pneumatic clamping jaw 3. Subsequently, the second lifting cylinder 22 moves the pneumatic clamping jaw 3 downward, so that the part picked up by the pneumatic clamping jaw 3 is embedded in the fixture cavity at the placing position, and the pneumatic clamping jaw 3 releases the material, causing the material to separate from the pneumatic clamping jaw 3. Then the second lifting cylinder 22 resets the pneumatic clamping jaw 3, completing the picking and transfer operations of the two groups of materials.

[0021] In some embodiments, the first lifting cylinder 21 and the second lifting cylinder 22 are lifted and lowered simultaneously, driving the two groups of pneumatic grippers 3 to pick up and place materials at the same time, effectively improving the efficiency of the overall material picking and placing operation.

[0022] When replacing parts, the pneumatic gripper 3 corresponding to the first lifting cylinder 21 is moved above the loading and unloading platform by the manipulator 4. The first lifting cylinder 21 is started, so that the pneumatic gripper 3 moves to the material picking position, and the pneumatic gripper 3 is started to pick up the material. Then the first lifting cylinder 21 drives the pneumatic gripper 3 to reset, and the support plate 1 is moved above the working platform by the manipulator 4. The first lifting cylinder 21 is started, and the pneumatic gripper 3 is moved downward, so that the part picked up by the pneumatic gripper 3 is embedded in the fixture cavity of the working platform, and the material is released through the pneumatic gripper 3, so that the material is separated from the pneumatic gripper 3. Then the first lifting cylinder 21 resets the pneumatic gripper 3. Then the manipulator 4 moves the pneumatic gripper 3 corresponding to the second lifting cylinder 22 to the corresponding position of the material that has been processed on the working platform. The second lifting cylinder 22 is started, so that the pneumatic gripper 3 moves to the material picking position, and the pneumatic gripper 3 is started to pick up the material. Then the second lifting cylinder 22 drives the pneumatic gripper 3 to reset, and the support plate 1 is moved above the loading and unloading platform by the manipulator 4. The second lifting cylinder 22 is started, and the pneumatic gripper 3 is moved downward, so that the part picked up by the pneumatic gripper 3 is embedded in the fixture cavity of the loading and unloading platform, and the material is released through the pneumatic gripper 3, so that the material is separated from the pneumatic gripper 3. Then the second lifting cylinder 22 resets the pneumatic gripper 3, completing the operation of replacing the material once.

[0023] In some embodiments, after the pneumatic gripper 3 connected to the first lifting cylinder 21 picks up the part to be processed, the manipulator 4 moves the support plate 1 above the working platform. First, the pneumatic gripper 3 connected to the second lifting cylinder 22 takes out the processed part, and then the pneumatic gripper 3 connected to the first lifting cylinder 21 places the part to be processed on the working platform for processing, which can effectively improve the overall efficiency.

[0024] In summary, in the present utility model, the first lifting cylinder 21 and the second lifting cylinder 22 are respectively arranged on the two side surfaces of the support plate 1, so that the pneumatic grippers 3 on both sides can be as close as possible to the central axis of the support plate 1, thereby effectively reducing the space occupied by the overall mechanism, avoiding interference or collision with other mechanisms during the movement, and effectively improving the overall safety. At the same time, by making the pneumatic gripper 3 as close as possible to the central axis of the support plate 1, the center of gravity of the overall mechanism is more stable, improving the stability during the picking and moving of the parts.

[0025] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
