On the other hand, product development must meet the diverse needs of consumers; products are often diversified and rapidly updated, requiring production lines to have a certain degree of flexibility to accommodate the production of different products. Therefore, designing a simple and reliable fixture for loading materials into automated equipment such as robots is particularly important.

[0003] Currently, robots are used for loading and unloading. Cylinder clamps hold the top and bottom surfaces of the cylinder or the intake and exhaust side protrusions on the top surface. At present, cylinder clamps are dedicated and different cylinder clamps are not interchangeable. Therefore, a large number of cylinder clamps need to be designed and quick-change clamps are used to switch between clamps.

[0004] Replacing different fixtures with different cylinder models involves significant investment, requires setting up different fixture racks, occupies a large area of ​​the production line, and may result in insufficient robot coverage.

[0010] In the aforementioned multi-functional cylinder clamp, preferably, the lower end of the rod has a threaded mounting post, the diameter of which is smaller than the diameter of the rod, and the clamping block is mounted on the threaded mounting post and fixed by a locking nut.

[0011] In the aforementioned multi-functional cylinder clamp, preferably, the positioning mechanism includes a first positioning mechanism displacement component, a second positioning mechanism displacement component, and a positioning block.

[0026] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] Embodiments of the present invention: such as Figures 1-10 As shown, a multifunctional cylinder block clamp includes a clamp bracket 1, which is connected to a robot. The clamp bracket 1 is provided with a first clamping mechanism 2 and a second clamping mechanism 3. The bottom of the clamp bracket 1 is provided with a positioning mechanism 4. The positioning mechanism 4 is inserted into a pin hole on the top surface of the cylinder block. The first clamping mechanism 2 and the second clamping mechanism 3 are respectively inserted into the cylinder block through the cylinder hole and abut against the crankcase blank surface.

[0028] Specifically, the fixture bracket 1 includes a robot connecting flange 5, a connecting frame 6, and a mounting plate 7. The lower end of the connecting frame 6 is fixedly connected to the middle part of the mounting plate 7, and the upper end of the connecting frame 6 is fixedly connected to the robot connecting flange 5.

[0029] The robot connecting flange 5 has a disc-shaped structure with a ring of mounting holes. Bolts are used to secure the robot connecting flange 5 to the robot through these holes. The robot is an existing product and can be purchased directly. It is used to control a multi-functional cylinder gripper to grasp or release cylinders. After grasping the cylinder, the robot can change its position, achieving automated cylinder handling. The specific structure and working principle of the robot are existing technologies and are not within the scope of this invention; therefore, they will not be described further in this embodiment.

[0030] Mounting plate 7 is a rectangular flat plate structure. Mounting plate 7 is used to fix the first clamping mechanism 2, the second clamping mechanism 3 and the positioning mechanism 4. Side baffles 36 are fixed on the two long sides of mounting plate 7. The side baffles 36 can protect the lower ends of the first clamping mechanism 2 and the second clamping mechanism 3 to prevent collisions.

[0031] The mounting plate 7 has two oblong holes 11 located on both sides of the connecting frame 6. To improve the versatility of the invention, the positions of the first clamping mechanism 2 and the second clamping mechanism 3 are adjustable. Therefore, two oblong holes 11 are required to ensure that the movement of the first clamping mechanism 2 and the second clamping mechanism 3 is not obstructed. By adjusting the positions of the first clamping mechanism 2 and the second clamping mechanism 3, the invention can be applied to clamping different models of cylinders, thus improving its versatility.

[0032] A lower through hole 37 is provided at the center of the mounting plate 7. The connecting frame 6 has a hollow structure inside, and both the upper and lower ends of the connecting frame 6 are open structures. An upper through hole 38 is provided at the center of the robot connecting flange 5. Wires, air pipes, etc. can pass through the upper through hole 38, the interior of the connecting frame 6, and the lower through hole 37 in sequence to extend to the bottom of the mounting plate 7 and connect with the relevant structure at the bottom of the mounting plate 7 to provide power and compressed gas.

[0033] Furthermore, the first clamping mechanism 2 and the second clamping mechanism 3 have the same structure. Both include a horizontal position adjustment component, a rotary cylinder 8, and a clamping cylinder 9. The rotary cylinder 8 is mounted on the mounting plate 7 through the horizontal adjustment component. A connecting plate 12 is fixed to the top of the rotary cylinder 8. The clamping cylinder 9 is fixed on the connecting plate 12, and a rod 10 is connected to the clamping cylinder 9. The rod 10 passes through the connecting plate 12, the rotary cylinder 8, and the oblong hole 11. The lower end of the rod 10 has a threaded mounting post. The diameter of the threaded mounting post is smaller than the diameter of the rod 10, thus forming a limiting boss at the connection position of the two. The clamping block 13 is mounted on the threaded mounting post and fixed by the locking nut 19.

[0034] To ensure that the rod 10 can move up and down and rotate smoothly, an oil-free bushing and a sleeve 39 are fixed on the mounting plate 7. The rod 10 can slide up and down within the sleeve 39 and can also rotate within the sleeve 39.

[0035] The horizontal position adjustment component is used to adjust the position of the rod 10, thereby changing the distance between the rod 10 on the first clamping mechanism 2 and the rod 10 on the second clamping mechanism 3, so as to be suitable for different models of cylinders.

[0036] Both the rotary cylinder 8 and the clamping cylinder 9 are commercially available products and can be purchased directly. The clamping cylinder 9 is used to adjust the position of the rod 10 in the vertical direction, and the rotary cylinder 8 is used to drive the rod 10 to rotate. The angle of the clamping block 13 is adjusted by rotating the rod 10.

[0037] Furthermore, the horizontal position adjustment assembly includes a cylinder mounting bracket 14, a clamping mechanism displacement cylinder 15, a fixed bracket 16, a slide rail 17, and a slider 18. The slide rail 17 is fixed on the mounting plate 7. Slide rails 17 are provided on both sides of the waist-shaped hole 11. The slide rail 17 is parallel to the long axis of symmetry of the waist-shaped hole 11 and parallel to the long side of the mounting plate 7. A slider 18 is provided at the bottom of the fixed bracket 16. The slider 18 is mounted on the slide rail 17 and the two slide in cooperation. The lower end of the rotary cylinder 8 is fixed on the fixed bracket 16. The cylinder mounting bracket 14 is arranged vertically and fixed on the side wall of the connecting frame 6. The clamping mechanism displacement cylinder 15 is fixed on the cylinder mounting bracket 14. The piston rod of the clamping mechanism displacement cylinder 15 is connected to the fixed bracket 16.

[0038] It should be noted that the slider 18 can move smoothly on the slide rail 17 and will not disengage from the slide rail 17 in the vertical direction. Through the cooperation between the slider 18 and the slide rail 17, the first clamping mechanism 2 and the second clamping mechanism 3 can be smoothly displaced.

[0039] When repositioning is required, the piston rod of the repositioning cylinder 15 of the clamping mechanism drives the fixed bracket 16 to move. The sliding cooperation of the slider 18 on the slide rail 17 enables the fixed bracket 16 to move smoothly. During the movement, the rotating cylinder 8 and the clamping cylinder 9 on it move synchronously, thereby changing the position of the rod 10.

[0040] To prevent the slider 18 from detaching from the end of the slide rail 17 away from the clamping mechanism displacement cylinder 15, a limiting block 40 is preferably fixed on the wide side of the mounting plate 7. The limiting block 40 can block the fixed bracket 16, which on the one hand ensures that the fixed bracket 16 can be accurately positioned, and on the other hand prevents the fixed bracket 16 from moving excessively.

[0041] Furthermore, the positioning mechanism 4 includes a first positioning mechanism displacement component 20, a second positioning mechanism displacement component 21, and a positioning block 22. The positioning block 22 is fixed to the bottom of the mounting plate 7. The first positioning mechanism displacement component 20 is located near one of the long sides of the mounting plate 7, and the second positioning mechanism displacement component 21 is located near the other long side of the mounting plate 7.

[0042] It should be noted that there are multiple positioning blocks 22, and the positioning blocks 22 have different shapes. The shape and position of the positioning blocks 22 are selected and set according to actual needs. Please refer to... Figure 7 A cylindrical positioning block 22 is set at one of the diagonals of the mounting plate 7, a cuboid positioning block 22 is set at the center of the bottom surface of the mounting plate 7, and a strip-shaped positioning block 22 is set at the edge of the two short sides of the bottom surface of the mounting plate 7. In order to ensure that the positioning blocks 22 are tightly attached to the top surface of the cylinder, this embodiment also sets two air detection blocks 34. These two air detection blocks 34 are used in conjunction with the two strip-shaped positioning blocks 22. When the positioning blocks 22 are tightly attached to the top surface of the cylinder, the positioning blocks 22 are deformed by pressure, thereby completely blocking the air outlet of the air detection blocks 34. The air detection blocks 34 have air pressure sensors. Since the air outlet of the air detection blocks 34 is completely blocked, the air pressure value inside the air detection blocks 34 will rise to a preset value. The robot can determine that the positioning blocks 22 are tightly attached to the top surface of the cylinder when it obtains this pressure signal. If the positioning block 22 is not tightly fitted to the top surface of the cylinder, the positioning block 22 cannot be connected to the air outlet of the air detection block 34, or cannot completely block the air detection block 34. The gas pressure inside the air detection block 34 cannot reach the preset value. The robot can determine that the positioning block 22 is not completely tightly fitted to the top surface of the cylinder when it obtains the pressure signal.

[0043] Furthermore, the first positioning mechanism displacement assembly 20 and the second positioning mechanism displacement assembly 21 have the same structure. Both include a push-pull cylinder 23, a support slider 24, a first positioning pin 25, a second positioning pin 26, a fixing block 27, a spring 28, a baffle 29, a cover plate 30, and a positioning pin limiting block 35. The push-pull cylinder 23 is fixed to the bottom of the mounting plate 7 by a cylinder bracket 27, and the fixing block 27 is fixed to the bottom of the mounting plate 7. The fixing block 27 has two positioning pin mounting holes, and the first positioning pin 25 and the second positioning pin 26 are respectively inserted into the two positioning pin mounting holes. Each component is equipped with a spring 28. A groove is provided on the bottom surface of the fixing block 27. The support slider 24 is slidably installed in the groove. One end of the support slider 24 is connected to the piston rod of the push-pull cylinder 23 through the connecting rod 31. The positioning pin limit block 35, the baffle 29 and the cover plate 30 are fixed to the bottom of the fixing block 27 by bolts. In order to ensure that the first positioning pin 25 and the second positioning pin 26 can move smoothly, two bushings 41 are provided in the positioning pin mounting hole of the positioning pin limit block 35. It should be noted that the baffle 29 and the cover plate 30 are both provided with two holes for the first positioning pin 25 and the second positioning pin 26 to pass through.

[0044] Two retaining rings 32 are fixed on both the first positioning pin 25 and the second positioning pin 26. The distance between the two retaining rings 32 is equal to the thickness of the supporting slider 24. The supporting slider 24 has an irregular through hole 33 that is larger in the middle and smaller at both ends. The width at both ends of the irregular through hole 33 is equal to the diameter of the first positioning pin 25 and the second positioning pin 26, and the width in the middle of the irregular through hole 33 is equal to the outer diameter of the retaining ring 32.

[0045] The positioning pin limiting block 35 is installed on the fixed block 27 to restrict the vertical position of the support slider 24, so that the support slider 24 can only move horizontally within the groove on the bottom surface of the fixed block 27. The diameter of the two bushings 41 on the positioning pin limiting block 35 is smaller than the outer diameter of the retaining ring 32. Therefore, the retaining ring 32 cannot continue to move after contacting the top surface of the positioning pin limiting block 35. Thus, the positioning pin limiting block 35 can also limit the maximum downward movement of the first positioning pin 25 and the second positioning pin 26.

[0046] It should be noted that the first positioning mechanism displacement component 20 and the second positioning mechanism displacement component 21 have the same structure and work on the same principle, but the arrangement of the first positioning pin 25 and the second positioning pin 26 on them is slightly different.

[0047] When the first positioning mechanism displacement assembly 20 and the second positioning mechanism displacement assembly 21 are working, only one positioning pin is active, while the other positioning pin is inactive. By changing the working state of the positioning pin, different models of cylinder blocks can be positioned.

[0048] The working principle of this invention is as follows: During operation, the working states of the rotary cylinder 8, clamping cylinder 9, clamping mechanism displacement cylinder 15, push-pull cylinder 23, and air detection block 34 are all controlled by the robot. After the robot obtains the specific model of the cylinder to be grasped, it first adjusts the state of the first positioning mechanism displacement component 20 and the second positioning mechanism displacement component 21. When the piston rod of the push-pull cylinder 23 extends, the support slider 24 moves away from the push-pull cylinder 23. The end of the irregular through hole 33 near the push-pull cylinder 23 contacts the second positioning pin 26. At this time, the retaining ring 32 on the second positioning pin 26 cannot pass through the irregular through hole 33 and is supported by the support slider 24. At the same time, the first positioning pin 25 is in the area with a larger width of the irregular through hole. When the first positioning pin 25 contacts the top surface of the cylinder, it moves into the positioning pin mounting hole on the fixing block 27 and simultaneously compresses the spring 28. Because the second positioning pin 26 is supported by the support slider 24, the second positioning pin 26 is inserted into the positioning hole in the cylinder.

[0049] When the first positioning pin 25 needs to be inserted into the positioning hole on the cylinder body, the push-pull cylinder 23 is controlled to retract, and the support slider 24 moves towards the push-pull cylinder 23. The end of the irregular through hole 33 away from the push-pull cylinder 23 contacts the first positioning pin 25. At this time, the retaining ring 32 on the first positioning pin 25 cannot pass through the irregular through hole 33 and is supported by the support slider 24. At the same time, the second positioning pin 26 is in the area with a larger width of the irregular through hole. When the second positioning pin 26 contacts the top surface of the cylinder body, it moves into the positioning pin mounting hole on the fixing block 27 and simultaneously squeezes the spring 28. Because the first positioning pin 25 is supported by the support slider 24, the first positioning pin 25 does not move axially and can be smoothly inserted into the positioning hole in the cylinder body.

[0050] After adjusting the state of the first positioning mechanism displacement component 20 and the second positioning mechanism displacement component 21, adjust the position of the first clamping mechanism 2 and the second clamping mechanism 3 according to the cylinder model, so that the rod 10 on the first clamping mechanism 2 and the second clamping mechanism 3 can be accurately inserted into the cylinder bore of the cylinder.

[0051] When repositioning is required, the piston rod of the repositioning cylinder 15 of the clamping mechanism drives the fixed bracket 16 to move. The sliding cooperation of the slider 18 on the slide rail 17 enables the fixed bracket 16 to move smoothly. During the movement, the rotating cylinder 8 and the clamping cylinder 9 on it move synchronously, thereby changing the position of the rod 10.

[0052] Taking a four-cylinder cylinder block as an example, the robot connects the present invention to the cylinder block. Rod 10 on the first clamping mechanism 2 is inserted into the first cylinder bore of the cylinder block, and rod 10 on the second clamping mechanism 3 is inserted into the fourth cylinder bore. Since rod 10 is eccentric within the cylinder bore, it does not interfere with insertion. After connection, the air detection block 34 checks whether each positioning block 22 is tightly fitted to the top surface of the cylinder block. If tightly fitted, the rotary cylinder 8 is controlled to rotate rod 10 by 90°, and then the clamping cylinder 9 is controlled to retract, causing the clamping block 13 to fit against the crankcase blank surface of the cylinder block, completing the clamping of the cylinder block. The robot then transports the cylinder block to a preset position. The release of the cylinder block is the reverse process of gripping, which will not be described further here.

[0053] This invention can meet the positioning and clamping needs of cylinders of different types and platforms, facilitating automated handling of different cylinders, effectively improving production efficiency and reducing production line investment. The invention has a simple structure, is easy to operate, safe and environmentally friendly, and reliable in use, making it highly valuable for widespread application.

[0054] The above description, based on the embodiments shown in the figures, details the structure, features, and effects of the present invention. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, that do not exceed the spirit covered by the specification and figures, should be within the protection scope of the present invention.
