Description

Technical Field

[0001] The utility model relates to a positioning device for assembling an oil return cylinder, belonging to the technical field of hydraulic systems. Background Art

[0002] At present, wheel loaders are all equipped with a hydraulic oil tank for supplying oil to the hydraulic system. A return oil cylinder is installed on the hydraulic oil tank. The main function of the return oil cylinder is to ensure that the hydraulic oil can return to the hydraulic oil tank smoothly after completing the work so that it can be hydraulically pumped into the hydraulic system again to realize the recycling of the hydraulic oil.

[0003] The oil return cylinder is usually made of multiple parts spliced ​​together by welding. During the splicing process, mounting holes need to be opened on the cylinder body to facilitate welding and fixing of the pipe joints.

[0004] During the drilling process, the cylinder body needs to be positioned using a fixture. Currently, the cylinder body is generally positioned horizontally, which can lead to inaccurate positioning of the ends, resulting in deviations in the placement of the mounting holes. After drilling, the cylinder body must be manually removed from the fixture, which is inconvenient.

[0005] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0006] In response to the deficiencies in the background technology, the utility model provides a positioning device for assembling an oil return cylinder, which can clamp and position the cylinder in the longitudinal direction, ensure automatic and precise positioning of its end, and the cylinder after the hole is opened can be automatically flipped out of the clamp to reduce human participation.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] The positioning device for assembling the oil return cylinder includes a frame, and two clamps are installed inside the frame, which are symmetrically arranged on the left and right. The inner sides of the two clamps are both arc-shaped structures, and the two clamps are used to clamp the cylindrical workpiece in opposite directions.

[0009] A positioning support plate and a conveyor belt are provided below the two clamping molds.

[0010] The positioning support plate is a right-angle structure, consisting of a horizontal part and a vertical part connected vertically, and the vertical part is connected to the output end of the rotary cylinder by bolts;

[0011] One end of the rotary cylinder away from the positioning support plate is fixedly connected to a vertically arranged transverse plate, and one side of the transverse plate away from the rotary cylinder is connected to the second cylinder head.

[0012] Furthermore, the outer sides of the two clamping dies facing each other are fixedly connected with clamping die seats.

[0013] Furthermore, one of the mold clamping seats is connected to the head of the first cylinder, and the cylinder body of the first cylinder is fixed to the outer side of the frame along the horizontal direction.

[0014] Furthermore, another clamping die seat is connected to a fixing rod, and the fixing rod is fixed to the inner side of the frame along the horizontal direction.

[0015] Furthermore, the cylinder body of the second cylinder is fixed to the outer side of the frame along the horizontal direction.

[0016] Furthermore, the second cylinder is located directly below the first cylinder.

[0017] Furthermore, a horizontally arranged guide rod is installed below the second cylinder.

[0018] Furthermore, the inner end of the guide rod is fixedly connected to the transverse plate.

[0019] Furthermore, the main body of the guide rod is inserted into the linear bearing.

[0020] Furthermore, the linear bearing is fixedly connected to the frame.

[0021] Compared with the prior art, the present invention has the following advantages after adopting the above technical solution:

[0022] The cylindrical workpiece to be processed is placed on the horizontal part of the positioning support plate, which positions the bottom end of the cylindrical workpiece. Then the first cylinder extends, and the two clamps clamp the cylindrical workpiece towards each other, ensuring the automatic and accurate positioning process.

[0023] After the hole of the cylindrical workpiece is opened, the first cylinder retracts and drives the clamp to move left, releasing it from the clamping position. The second cylinder retracts and drives the positioning plate and the cylindrical workpiece to move a certain distance to the left. The rotating cylinder then drives the positioning plate to flip over, automatically turning the cylindrical workpiece onto the conveyor belt, realizing automatic transfer and reducing manpower involvement.

[0031] like Figure 1-Figure 4 As shown together, the utility model provides a positioning device for assembling an oil return cylinder, including a frame 1, and two clamps 2 symmetrically arranged on the left and right are installed inside the frame 1. The facing inner sides of the two clamps 2 are both arc-shaped structures, and the two clamps 2 are used to achieve opposite clamping of the cylindrical workpiece 12.

[0032] The two clamping molds 2 are fixedly connected to the outer sides thereof, wherein one of the clamping mold bases 3 is connected to the head of the first cylinder 4, the cylinder body of the first cylinder 4 is fixed to the outer side of the frame 1 in the horizontal direction, and the other clamping mold base 3 is connected to the fixing rod 13, and the fixing rod 13 is fixed to the inner side of the frame 1 in the horizontal direction.

[0033] A positioning support plate 5 and a conveyor belt 11 are sequentially provided below the positions where the two clamping dies 2 are located.

[0034] The positioning plate 5 is a rectangular structure consisting of a horizontal portion and a vertical portion connected perpendicularly. The horizontal portion is used to support and position the bottom end of the cylindrical workpiece 12, while the vertical portion is connected to the output end of the rotary cylinder 6 via bolts. The rotary cylinder 6 can drive the positioning plate 5 to flip, thereby flipping the processed cylindrical workpiece 12 onto the conveyor belt 11 for automatic transportation to the next workstation.

[0035] The end of the rotating cylinder 6 away from the positioning support plate 5 is fixedly connected to the vertically arranged transverse plate 7, and the side of the transverse plate 7 away from the rotating cylinder 6 is connected to the head of the second cylinder 8.

The second cylinder 8 provides power for the lateral movement of the positioning support plate 5.

[0036] A horizontal guide rod 9 is mounted below the second cylinder 8. The inner end of the guide rod 9 is fixedly connected to the transverse plate 7. The main body of the guide rod 9 is inserted into a linear bearing 10, which is fixedly connected to the frame 1. The movement of the guide rod 9 along the linear bearing 10 ensures smooth transverse movement of the positioning support plate 5.

[0037] The specific working principle of this utility model:

[0038] like Figure 4As shown, the cylindrical workpiece 12 to be processed is placed on the horizontal part of the positioning support plate 5, and the positioning support plate 5 positions the bottom end of the cylindrical workpiece 12. Then the first cylinder 4 is extended, and the two clamps 2 clamp and position the cylindrical workpiece 12 towards each other; then the drilling equipment is used to drill a hole in the cylindrical workpiece 12 that has been positioned and clamped. After the drilling is completed, the first cylinder 4 retracts and drives the clamp 2 to move left, and disengages from the clamping of the cylindrical workpiece 12. After the second cylinder 8 retracts and drives the positioning support plate 5 and the cylindrical workpiece 12 to move a certain distance to the left, the rotating cylinder 6 drives the positioning support plate 5 to flip, and the cylindrical workpiece 12 is automatically turned over to the conveyor belt 11, and automatically transported to the next workstation.
