Description

Technical Field

[0001] This utility model relates to the field of processing machinery technology, and in particular to a vertical gripper. Background Technology

[0002] In machining processes, grippers are used to grasp materials. Because vertical grippers are installed vertically, when the gripper is holding a heavy object or the air supply is cut off, the gripper will be affected by its own weight or the weight of the object, causing the gripper to open and the material to fall, affecting its use. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, an embodiment of this utility model proposes a vertical gripper, including a cylinder, a first claw body, and a second claw body; the cylinder includes a piston rod, on which a push-pull rod is horizontally inserted, and the piston rod moves the push-pull rod up and down;

[0004] The first claw body is provided with a first sliding groove, the first clamping surface faces directly downwards, and the first sliding groove is arranged longitudinally. One end of the push-pull rod slides within the first sliding groove. The second claw body is connected to the first claw body by a pin, and the second claw body rotates around the pin. The second claw body is provided with a second sliding groove, and the other end of the push-pull rod slides within the second sliding groove. The second sliding groove includes a vertical section, an arc-shaped section, and a isthmus. When the push-pull rod is located in the vertical section, the vertical section is above the arc-shaped section, and the first claw body and the second claw body remain in a closed state, allowing the first claw body and the second claw body to cooperate in clamping the material. When the push-pull rod is located in the arc-shaped section, the first claw body and the second claw body remain in an open state, allowing the first claw body and the second claw body to release the material. The push-pull rod is pushed and pulled by the cylinder, causing the push-pull rod to pass through the isthmus and enter the vertical section or the arc-shaped section.

[0005] This utility model has at least the following beneficial effects:

[0006] When clamping materials, when the push-pull rod is pushed downwards by the cylinder to the curved section, the first and second claws remain open, allowing them to release or prepare to clamp the material. When the push-pull rod is pulled upwards by the cylinder to the vertical section, the first and second claws remain closed, allowing them to grip the material. Simultaneously, due to the change in curvature between the vertical and curved sections, the push-pull rod cannot smoothly transition from the vertical section to the curved section when the second claw is subjected to its own weight or the weight of a heavy object. This achieves self-locking of the gripper, preventing it from opening during use and causing the material to fall, thus affecting its operation.

[0007] According to some embodiments of the present invention, the first claw body is further provided with a first clamping surface, and a first clamping block is mounted on the first clamping surface; the second claw body is further provided with a second clamping surface, and a second clamping block is mounted on the second clamping surface, wherein the first clamping block and the second clamping block cooperate to clamp the material.

[0008] According to some embodiments of the present invention, the first clamping block is provided with a first anti-slip surface, the second clamping block is provided with a second anti-slip surface, and the first anti-slip surface and the second anti-slip surface are in contact with the material;

[0009] The first anti-slip surface is provided with a first conical tooth pattern, and the second anti-slip surface is provided with a second conical tooth pattern, wherein the first conical tooth pattern and the second conical tooth pattern are staggered and overlap.

[0010] According to some embodiments of the present invention, the first claw body is further provided with a protrusion, and the second claw body is equipped with a limiting block. The limiting block cooperates with the protrusion, and the limiting block and the protrusion are used to limit the angle at which the second claw body rotates and opens.

[0011] According to some embodiments of the present invention, the cylinder further includes a main body, and the lower part of the main body is provided with two mounting plates. The two ends of the pin are respectively inserted into the two mounting plates, so that the first claw body and the second claw body are mounted between the two mounting plates. Both mounting plates are provided with longitudinal sliding grooves, and the two ends of the push-pull rod are respectively equipped with sliders, and the two sliders slide in the two longitudinal sliding grooves respectively.

[0012] According to some embodiments of this utility model, it also includes spring sheets, wherein two spring sheets are used, and the two spring sheets are respectively covered on the longitudinal sliding groove, and the spring sheets are in contact with the end of the push-pull rod.

[0013] According to some embodiments of this utility model, a pressure plate is pressed onto the spring sheet, and the friction between the spring sheet and the end of the push-pull rod is adjusted by the pressure plate.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Reference Figure 1 , 2 As shown, a vertical gripper includes a cylinder 100, a first gripper body 200, and a second gripper body 300. The cylinder 100 includes a piston rod 110, on which a push-pull rod 120 is horizontally inserted. The piston rod 110 moves the push-pull rod 120 up and down. The first gripper body 200 is provided with a first sliding groove 210, and a first clamping surface 220 faces directly downward. The first sliding groove 210 is arranged longitudinally, and one end of the push-pull rod 120 slides within the first sliding groove 210. The second gripper body 300 is connected to the first gripper body 200 by a pin 400. The second gripper body 300 rotates about the pin 400 as an axis. The second gripper body 300 is provided with a second sliding groove 310, which allows for pushing and pulling. The other end of the rod 120 slides within the second slide groove 310, which includes a vertical section 311, an arc-shaped section 312, and a isthmus 313. When the push-pull rod 120 is located in the vertical section 311, the first claw body 200 and the second claw body 300 remain closed, allowing them to clamp the material. When the push-pull rod 120 is located in the arc-shaped section 312, the first claw body 200 and the second claw body 300 remain open, allowing them to release the material. The cylinder 100 pushes and pulls the push-pull rod 120, causing it to pass through the isthmus 313 and enter the vertical section 311 or the arc-shaped section 312.

[0032] During material clamping, when the push-pull rod 120 is pushed downwards by the cylinder 100 to the curved section 312, the first claw 200 and the second claw 300 remain open, allowing them to release or prepare to clamp the material. Conversely, when the push-pull rod 120 is pulled upwards by the cylinder 100 to the vertical section 311, which is above the curved section 312, the first claw 200 and the second claw 300 remain closed. The first claw body 200 and the second claw body 300 work together to clamp the material. At the same time, due to the change in curvature between the vertical section 311 and the curved section 312, the push-pull rod 120 cannot smoothly pass through the isthmus 313 and enter the curved section 312 from the vertical section 311 when the second claw body 300 is subjected to its own weight or the weight of the object. It must be assisted by the cylinder 100 to apply force, thereby achieving the self-locking of the gripper and preventing the gripper from being opened during use, causing the material to fall and affecting the use.

[0033] Reference Figure 2 , 3 As shown, the first claw body 200 is also provided with a first clamping surface 220, which faces downward when clamping, and a first clamping block 230 is mounted on the first clamping surface 220; the second claw body 300 is also provided with a second clamping surface 320, which faces upward when clamping, and a second clamping block 330 is mounted on the second clamping surface 320. The material is clamped by the cooperation of the first clamping block 230 and the second clamping block 330, which further improves the stability of the material when it is clamped.

[0034] Reference Figure 10 , 11 As shown, in order to effectively prevent material slippage, a first anti-slip surface 231 is provided on the first clamping block 230, and a second anti-slip surface 331 is provided on the second clamping block 330. The first anti-slip surface 231 and the second anti-slip surface 331 are in contact with the material.

[0035] Furthermore, a first conical tooth pattern 232 is provided on the first anti-slip surface 231, and a second conical tooth pattern 332 is provided on the second anti-slip surface 331, with the first conical tooth pattern 232 and the second conical tooth pattern 332 being staggered and overlapping.

[0036] Reference Figure 3 As shown, the first claw body 200 is also provided with a protrusion 240, and the second claw body 300 is equipped with a limiting block 340. The limiting block 340 cooperates with the protrusion 240, and the angle of rotation of the second claw body 300 is limited by the cooperation between the limiting block 340 and the protrusion 240.

[0037] Reference Figure 2 , 3As shown, the cylinder 100 also includes a body 130. The body 130 has a chamber 131 inside, and a piston block 140 is installed inside the chamber 131. The piston block 140 is connected to the piston rod 110 and is used to move the piston rod 110 up and down.

[0038] Reference Figure 8 , 9 As shown, the main body 130 is provided with a first air passage 132 and a second air passage 133. One end of the first air passage 132 opens into the upper part of the chamber 131, and the other end of the first air passage 132 opens into the side wall of the main body 130; one end of the second air passage 133 opens into the lower part of the chamber 131, and the other end of the second air passage 133 opens into the side wall of the main body 130.

[0039] When the first air passage 132 is used for air intake and the second air passage 133 is used for air exhaust, the second claw body 300 opens against gravity. At the same time, the limiting block 340 and the protrusion 240 cooperate to limit the angle at which the second claw body 300 rotates and opens.

[0040] When the first air passage 132 exhausts air and the second air passage 133 intakes air, the second claw body 300 closes the gripper using gravity and air pressure.

[0041] Reference Figure 1 As shown, it can also be connected to an external air source through the air nozzles 150 on the first air passage 132 and the second air passage 133.

[0042] Reference Figure 1 , 7 As shown, the cylinder 100 also includes a main body 130. The lower part of the main body 130 is provided with two mounting plates 160. The two ends of the pin 400 are respectively inserted into the two mounting plates 160, so that the first claw body 200 and the second claw body 300 are mounted between the two mounting plates 160. Both mounting plates 160 are provided with longitudinal sliding grooves 161. The two ends of the push-pull rod 120 are respectively equipped with sliders 121, and the two sliders 121 slide in the two longitudinal sliding grooves 161 respectively.

[0043] Reference Figure 7 As shown, it also includes a spring sheet 800. Two spring sheets 800 are used, and the two spring sheets 800 are respectively covered on the longitudinal slide groove 161. The spring sheets 800 are in contact with the end of the push-pull rod 120. When the friction between the spring sheet 800 and the end of the push-pull rod 120 increases, the opening speed of the second claw body 300 slows down. When the friction between the spring sheet 800 and the end of the push-pull rod 120 decreases, the opening speed of the second claw body 300 increases.

[0044] A pressure plate 900 is pressed onto the spring sheet 800. By adjusting the pressing force of the pressure plate 900 on the spring sheet 800, the friction between the pressure plate 900 and the end of the push-pull rod 120 is changed.
