They can also be used in medical equipment, food processing equipment, printing equipment, and other fields to meet the needs of different industries for object gripping and manipulation.
[0003] When transporting precision items, existing dual-rail gripper cylinders require buffer structures at both ends to prevent damage to delicate or fragile objects. Existing buffer structures typically use springs and rubber with simple presets, which has some problems. For example, when the spring reaches its maximum value, it will not provide any buffer protection. Therefore, we propose a high-precision dual-rail gripper cylinder. Utility Model Content
[0004] The purpose of this invention is to provide a high-precision dual-guide rail gripper cylinder to solve the problems mentioned in the background art.

[0008] Furthermore, the top of the cylinder is symmetrically provided with two sets of guide rails, the bottom of the two sets of guide rails is provided with a second through hole, the inner walls of the two sets of guide rails are symmetrically provided with two sets of sliding grooves, the two sets of guide rails are slidably connected to the gripper, the left and right sides of the gripper are symmetrically fixed with two sets of sliders, the two sets of sliders are slidably disposed on the inner wall of the sliding groove, the bottom of the gripper located on the front side is fixedly connected to the second connecting block, the bottom of the gripper located on the rear side is fixedly connected to the first connecting block, the first connecting block and the second connecting block are respectively adapted to the second through hole and correspond one-to-one, and the top of the gripper is symmetrically provided with two sets of first mounting holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a cylinder, buffer components, etc., when the cylinder is transporting fragile objects, when the gripper reaches its maximum value, the blocks at both ends of the cylinder will contact the gripper. At the same time, the blocks will absorb some of the impact force first. Then, as the blocks transmit the force to the rectangular slide rod, the rectangular slide rod will compress the first spring at the other end, further absorbing some of the force. Simultaneously, the push rods at both ends of the rectangular slide rod will move synchronously, causing the push plate to slide and compress the space inside the oil chamber, thereby absorbing the final force and achieving protection for the fragile objects. Through the above design, precise offsetting of buffer force can be achieved, further protecting the safety of the objects during transportation. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-5 A high-precision dual-guide rail gripper cylinder, comprising cylinder 1;
[0020] Before use, cylinder 1 is installed in the designated position and installed through the second mounting hole 5 and the third mounting hole 9. Then, the pipe is connected to the air inlet and outlet 8 to provide power to cylinder 1. Then, the corresponding clamping component is installed on the top of the gripper 3. The clamping component is installed at the first mounting hole 4. In the above design, all of them are existing technologies. The specific operation process will not be described in detail here.
[0021] After cylinder 1 is installed, it is started to transport the corresponding object. When transporting some fragile or delicate objects, when the gripper 3 reaches the end of its stroke, the buffer component 2 will start to operate.
[0022] In this embodiment, the aforementioned buffer assembly 2 includes two sets of rectangular grooves 29 symmetrically installed on the top of the left and right sides of the cylinder 1. Two sets of buffer chambers 23 are installed inside the two sets of rectangular grooves 29 respectively. Two sets of oil reservoirs are symmetrically installed on the left and right sides of the buffer chambers 23 respectively. An anode assembly for absorbing buffering force is installed inside the oil reservoirs. Two sets of grippers 3 are also installed inside the cylinder 1. A set of first through holes 6 are respectively opened in the rectangular grooves 29 near the guide rail 11. A rectangular slide rod 30 is slidably connected to the inner wall of the first through hole 6. The rear outer wall of the rectangular slide rod 30 is connected to... The buffer chamber 23 is slidably connected. Two sets of first springs 10 are symmetrically fixed to the rear side of the rectangular slide rod 30. A partition plate 22 is fixed in the center of the rectangular groove 29. A stop block 31 is fixed to the front side of the rectangular slide rod 30. Connecting blocks are fixed to the left and right sides of the rectangular slide rod 30. A push rod 28 is fixed to the right end of the connecting block. A push plate 27 is fixed to the rear end of the push rod 28. The push plate 27 is slidably set in the oil chamber. An oil overflow plate 26 is fixed in the center of the inner wall of the oil chamber. A second spring 25 is adapted to the rear side of the oil overflow plate 26. An oil plate 24 is fixed to the rear end of the second spring 25.
[0023] Specifically, when the two sets of grippers 3 reach their ends, they will first contact the stop block 31. The main material of the stop block 31 is elastic silicone, which has a certain elasticity and can offset part of the force first. Then, as the grippers 3 move further, the rectangular slide bar 30 will slide in the direction of the grippers 3. The grippers 3 are set inside the buffer chamber 23. At the same time, there are two first springs 10 inside the grippers 3. When the first springs 10 are subjected to the force from the grippers 3, they will be compressed. It should be noted that there are two sets of first springs 10. At the same time, the compression value of the first springs 10 will not reach the maximum value.
[0024] Next, when the first spring 10 absorbs part of the force, a push rod 28 is connected to each of the two connecting blocks on both sides of the rectangular slide bar 30. Note that a partition 22 is provided in the middle of the rectangular groove 29. The main function of the partition 22 is to separate the parts. Subsequently, two oil chambers are fixed on the left and right sides of the buffer chamber 23. Note that a certain amount of oil is pre-filled in the oil chambers. When the rectangular slide bar 30 moves again, the push rod 28 will move accordingly. The push rod 28 will push the push plate 27 to slide in the oil chamber. Note that the push plate 27 itself is a piston plate. When it moves, it will compress the space inside the oil chamber. At the same time, the oil inside the oil chamber will flow to the bottom chamber through the overflow plate 26. At this time, the second spring 25 will be subjected to force and compressed, thereby absorbing the remaining force, so that the object transported by the gripper 3 can be protected.
[0025] When the grippers 3 move in opposite directions, the oil inside the bottom chamber of the oil chamber will return to the front chamber through the overflow plate 26 and return to the initial value. This process is repeated to ensure the safety of transportation.
[0026] Working principle: During use, when the two sets of grippers 3 reach their ends, they will first contact the stop block 31. The stop block 31 is mainly made of elastic silicone, which has a certain elasticity and can initially offset part of the force. Then, as the grippers 3 move further, the rectangular slide bar 30 will slide in the direction of the grippers 3. The grippers 3 are located inside the buffer chamber 23. Two first springs 10 are installed inside the grippers 3. When the first springs 10 are subjected to the force from the grippers 3, they will compress. It should be noted that there are two sets of first springs 10, and the compression value of the first springs 10 will not reach the maximum value. Then, when the first springs 10 have absorbed part of the force, the two sets of rectangular slide bars 30... Two connecting blocks on the side are each connected to a push rod 28. Note that a partition 22 is set in the middle of the rectangular groove 29. The main function of the partition 22 is to separate the parts. Then, two oil chambers are fixed on the left and right sides of the buffer chamber 23. Note that a certain amount of oil is pre-filled in the oil chambers. When the rectangular slide bar 30 moves, the push rod 28 will move accordingly. The push rod 28 will push the push plate 27 to slide in the oil chamber. Note that the push plate 27 itself is a piston plate. When it moves, it will compress the space inside the oil chamber. At the same time, the oil inside the oil chamber will flow to the bottom chamber through the overflow plate 26. At this time, the second spring 25 will be subjected to force and compressed, thereby absorbing the remaining force, so that the object transported by the gripper 3 can be protected.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
