Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing and relates to an automatic turning device for an upper cylinder cover. Background Art

[0002] When carrying out large-scale processing of compressor cylinder heads, a dedicated automated production line is used. After the inner diameter of the cylinder head is honed, it needs to be flipped over and then enter the deburring machine for deburring. The automated production line uses a translation robot for automatic loading and unloading. After that, the cylinder head needs to be manually flipped 180 degrees. The labor intensity is high, and manual participation in the flipping process is prone to safety hazards. If a fully automated multi-functional robot is used, the cost will be high.

[0003] To overcome the shortcomings of the existing technology, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a rapid positioning and flipping loading device for cylinder head parts [application number: 201520946364.9]. The device includes a flip loading workbench; a blank positioning table of the flip loading workbench is provided with multiple blank limit blocks; the flip loading workbench is also provided with a cylinder head spark plug hole insertion positioning mechanism and a cylinder head combustion chamber surface clamping mechanism; the cylinder head spark plug hole insertion positioning mechanism and the cylinder head combustion chamber surface clamping mechanism are both fixedly connected to the bottom of the blank positioning table. However, this solution is not suitable for flipping the upper cylinder head after the inner diameter honing is completed. It is difficult to flip the upper cylinder head 180 degrees and still requires manual assistance. This has the disadvantages of high labor intensity and relatively low safety and automation levels.

[0011] In the above-mentioned automatic turning device for the upper cylinder cover, the angle limiting structure includes a cylinder fixing block provided on the swing cylinder, and two limiting adjustment bolts corresponding to the positions of the swing limiting block are provided in the cylinder fixing block.

[0012] In the above-mentioned automatic turning device for the upper cylinder cover, the material sensing detection mechanism includes a material sensing bracket arranged on the side of the thin closed air claw cylinder, and the material sensing bracket is equipped with a sensor.

[0028] In this embodiment, air is supplied to the clamping mechanism 4. At this time, the clamping mechanism 4 is loosened, and the thin shaft portion of the upper end of the upper cylinder cover 100 is clamped by the translation manipulator, and translated to the middle of the clamping mechanism 4. The translation manipulator descends and sends the upper cylinder cover 100 into the middle of the clamping mechanism 4. The air of the clamping mechanism 4 is cut off, and the outer circular surface of the disc portion of the upper cylinder cover 10 is clamped by the clamping mechanism 4. After sensing that the clamping mechanism 4 is closed and clamped on the upper cylinder cover 10, the material sensing detection mechanism 7 sends a sensor signal and performs the next action. At this time, the vertical drive member 5 swings the cylinder mounting seat 2 and the swing The movable block 3 moves upward, and the flip driving part 6 drives the swing block 3 to swing 180 degrees, the swing cylinder mounting seat 2 and the swing block 3 descend, and the clamping mechanism 4 is released after air is supplied to the clamping mechanism 4, and the flipped upper cylinder cover 100 is placed on the conveyor belt, the swing cylinder mounting seat 2 and the swing block 3 rise again, the swing block 3 swings 180 degrees in the opposite direction, and the swing cylinder mounting seat 2 and the swing block 3 descend, and the cycle is repeated. Compared with the general manipulator, this device has a simple structure, low cost, good reliability, low labor intensity, high degree of automation and work efficiency.

[0029] Combine Figure 1-5As shown, the clamping mechanism 4 includes a thin closed air gripper cylinder 4a arranged at one end of the swing block 3 away from the swing cylinder mounting base 2, and two clamping seats 4b are connected to the thin closed air gripper cylinder 4a, and each clamping seat 4b is connected to a clamping block 4c.

[0030] Specifically, the thin closed air claw cylinder 4a is connected to an external air pipe. When the thin closed air claw cylinder 4a is supplied with air, the two clamping claw blocks 4c open. When there is no air, the two clamping claw blocks 4c can clamp the upper cylinder cover 100, and the degree of automation is relatively high.

[0031] The inner side of the clamping jaw block 4c has a plurality of transverse slots 4c1, which are symmetrically arranged along the center line of the clamping jaw block 4c.

[0035] The swing block 3 is provided with a swing limit block 3a, and the swing cylinder 6a is provided with an angle limit structure 8 that can abut against the swing limit block 3a.

[0036] In this embodiment, after the swing block 3 swings 180 degrees, the swing limit block 3a abuts against the angle limit structure 8, and the angle limit structure 8 limits the swing angle of the swing block 3 to ensure the accuracy of the flip angle.

After the swing block 3 swings 180 degrees, the swing limit block 3a abuts against the limit adjustment bolt 8b. The swing angle of the swing block 3 is limited by the limit adjustment bolt 8b to ensure the accuracy of the flipping angle. At the same time, the swing angle can be adjusted by adjusting the limit adjustment bolt 8b, which is very practical.

The upper thin shaft of the upper cylinder cover 100 is clamped by the translation manipulator, and translated to the middle of the clamping mechanism 4. The translation manipulator descends and sends the upper cylinder cover 100 into the middle of the two clamping claw blocks 4c. The thin closed air claw cylinder 4a is de-energized, and the two clamping claw blocks 4c are closed to clamp the outer circumferential surface of the disc of the upper cylinder cover 10. After sensing that the clamping claw blocks 4c are closed and clamping the upper cylinder cover 10, the sensor 7b sends a sensor signal and performs the next action. At this time, the lifting cylinder 5a swings the cylinder mounting base 2 and the swing block 3 Move upward, the swing cylinder 6a drives the swing block 3 to swing 180 degrees, the swing cylinder mounting base 2 and the swing block 3 fall, and the thin closed claw cylinder 4a is aired and the clamping claw block 4c is loosened. The flipped upper cylinder cover 100 is placed on the conveyor belt, and the swing cylinder mounting base 2 and the swing block 3 rise again, and the swing block 3 swings 180 degrees in the opposite direction. The swing cylinder mounting base 2 and the swing block 3 fall, and the cycle is repeated. Compared with the general manipulator, this device has a simple structure, low cost, good reliability, low labor intensity, high degree of automation and high work efficiency.

[0049] By setting a transverse groove 4c1 on the inner side of the clamping jaw block 4c, the upper cylinder cover 100 can be better clamped, and the chip cleaning straight groove 4c2 can facilitate subsequent staff to clean up the debris and prevent the debris from being retained between the clamping jaw block 4c and the upper cylinder cover 100.

[0050] The cylinder fixing block 8a is used to install the fixed limit adjustment bolt 8b. After the swing block 3 swings 180 degrees, the swing limit block 3a abuts against the limit adjustment bolt 8b. The swing angle of the swing block 3 is limited by the limit adjustment bolt 8b to ensure the accuracy of the flip angle. At the same time, the swing angle can be adjusted by adjusting the limit adjustment bolt 8b, which is very practical.

[0051] The lifting cylinder 5a is fixed to the turning manipulator mounting base 1 by bolts, which is simple and convenient to assemble and disassemble, and is convenient for the staff to perform subsequent maintenance and position adjustment.
