Description

Technical Field

[0001] This utility model relates to a blowing device for a transmission housing, belonging to the field of automotive automatic transmission manufacturing technology. Background Technology

[0002] In the field of automotive automatic transmission manufacturing technology, after the transmission housing has completed the pressure water test, sewage and debris will remain on its surface and in many threaded holes, mounting holes and oil holes, which need to be cleaned.

[0003] In existing technologies, manual cleaning with a handheld air gun is typically used to clean the gearbox housing 100%. However, due to the numerous and complex distribution of threaded holes in the gearbox housing, manual operation easily leads to missed areas or incomplete cleaning, resulting in the inability to completely remove wastewater and debris, making it difficult to effectively prevent quality problems. Manual operation requires an additional operator dedicated to the cleaning task, increasing labor costs on the production line. Furthermore, on-site observations show that manually cleaning a single gearbox housing takes up to 180 seconds, failing to meet production line flow rate requirements and becoming a bottleneck in production efficiency. In addition, the air gun cleaning process generates aluminum shavings and debris flying everywhere, causing environmental pollution and posing operational safety hazards, which does not meet the safety and environmental protection requirements of modern intelligent manufacturing.

[0013] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0014] A gearbox housing blowing device includes an inlet gate 1, a conveyor line 2, movable blowing nozzles 3, a control system 5, a movable cylinder 6, a blowing chamber 9, and an outlet gate 11. The conveyor line 2 passes through the blowing chamber 9. The inlet end of the blowing chamber 9 is sealed by the inlet gate 1, and the outlet end of the blowing chamber 9 is sealed by the outlet gate 11. The control system 5 is installed on the blowing chamber 9. The inner top wall of the blowing chamber 9 is fixedly connected to the fixed end of the horizontally arranged movable cylinder 6. The movable end of the movable cylinder 6 is fixedly connected to the middle of the horizontal bar of the n-shaped frame. The two vertical bars of the n-shaped frame are respectively arranged at the front and rear ends of the workpiece, and multiple movable blowing nozzles 3 are installed on each of the two vertical bars of the n-shaped frame. The multiple movable blowing nozzles 3 are all connected to the blowing system. A position sensor is installed in the middle of the inner bottom surface of the blowing chamber 9. The conveyor line 2, the inlet gate 1, the outlet gate 11, the movable cylinder 6, and the position sensor are all connected to the control system 5 for signal transmission.

[0015] Furthermore, the plurality of movable air nozzles 3 include two types: small nozzles of 1.0 mm corresponding to shallow holes and large nozzles of 1.5~2.0 mm corresponding to deep holes, totaling 12 nozzles. This allows for full coverage cleaning of more than 100 holes on the workpiece during operation. With fewer nozzles, greater compressed air force, and significant drying effect, the workpiece can be cleaned back and forth.

[0016] Furthermore, the inlet gate 1 and the outlet gate 11 are respectively fixedly connected to the movable end of the corresponding vertically arranged lifting cylinder 4. The fixed end of each lifting cylinder 4 is fixed to the top of the air blowing chamber 9. The inlet gate 1 and the outlet gate 11 are both sealed and slidably connected to the air blowing chamber 9. Each lifting cylinder 4 is connected to the control system 5 for signal transmission.

[0017] Furthermore, the side wall of the air-blowing chamber 9 is provided with a sealed safety door.

[0018] Furthermore, a frame 10 is fixed to the lower end of the air-blowing chamber 9.

[0019] Furthermore, a collection trough 8 for collecting debris and sewage is placed on the frame 10, and the bottom plate of the blower chamber 9 has a mesh structure, with the bottom plate of the blower chamber 9 corresponding to the collection trough 8.

[0020] The working process of this utility model is as follows: S1: Before cleaning the workpiece, this utility model is in standby mode, that is: both the inlet door 1 and the outlet door 11 are open, and the conveyor line 2 is in operation. S2: After the workpiece is taken out of the water tester, it is placed on the conveyor line 2 and automatically driven into the air blowing chamber 9. After traveling to the middle of the air blowing chamber 9, the position sensor sends a signal to the control system 5. The control system 5 controls the conveyor line 2 to stop working immediately and controls the lifting cylinder 4 to close the inlet door 1 and the outlet door 11. S3: After the workpiece is in place, the blowing system starts timing for 100 seconds, the blowing valve opens, the moving blowing nozzle 3 blows air, and at the same time the control system 5 controls the moving cylinder 6 to start driving the moving blowing nozzle 3 to move left and right. The displacement time / distance can be preset in the control system 5, or corresponding position sensors can be set at the left and right ends respectively and connected to the control system 5 for signal transmission, so as to realize the reciprocating movement after reaching the position. S4: Run the blowing operation according to the programmed blowing time, and move cylinder 6 for 100 seconds to complete the operation; S5: After the work is completed, the moving cylinder 6 is reset and the blower valve of the blower system is closed; S6: Control system 5 controls lifting cylinder 4 to open inlet gate 1 and outlet gate 11; S7: Control system 5 controls the conveyor line 2 to continue its transmission operation, transporting the workpiece to the next station.
