Description

Technical Field

[0001] The utility model belongs to the technical field of automotive automatic transmission testing, and particularly relates to a hydraulic torque converter process bushing conveying device. Background Art

[0002] Automotive automatic transmission testing is carried out on a total assembly test bench. The input shaft of the test bench is connected to the positioning shaft of the hydraulic torque converter through a process positioning pin. Since there are many types of hydraulic torque converters, in order to adapt to the connection size between the input shaft of the test bench and the positioning shaft of the hydraulic torque converter and meet the flexible needs, a process bushing needs to be installed on the positioning shaft of the hydraulic torque converter for size compensation to prevent axial movement caused by high-speed rotation and affect the test results. During batch production testing of automatic transmissions, for different models and sizes of hydraulic torque converters, there are differences in the size of the positioning center. To adapt to production, a process bushing needs to be installed on the positioning shaft before each automatic transmission test to make up for the size difference, reduce capital investment, and meet technical requirements. Usually, the process bushing is installed before the automatic transmission test and manually removed after the test for repeated use. During the entire test process, the process bushing plays an important role in auxiliary centering to ensure the stable rotation of the hydraulic torque converter. During batch production, if the process bushing is not installed, it will cause irreversible failures to the test bench and the automatic transmission, resulting in significant losses; if the process bushing is not removed in time after the test, it will affect the total assembly airtightness test, cleaning machine and other equipment in subsequent production processes, resulting in damage to the hydraulic torque converter and equipment and reducing the product manufacturing qualification rate.

[0037] Working process:

[0038] First, install the process bushing conveying device of the present utility model on one side of the automatic transmission production line body 6 (the process bushing conveying device is installed on one side of the automatic transmission production line body 6 through the fixed bracket 1). Place the automatic transmission in the automatic transmission tray 3. The automatic transmission tray 3 carries the automatic transmission and is transported to the corresponding position of the process bushing conveying device through the automatic transmission production line. At this time, first use the tray detection sensor 7 to detect the automatic transmission tray 3 to make it reach the designated position; then, the model detection sensor 8 detects the model of the automatic transmission. After detecting the automatic transmission, the anti - falling cylinder 12 acts to hold the hydraulic torque converter. The process bushing fixture 9 moves forward under the action of the process bushing cylinder 2 until it is completely sleeved on the process bushing of the hydraulic torque converter. After in place, the fixture cylinder 11 acts on the process bushing fixture 9, and the process bushing fixture 9 clamps the process bushing of the hydraulic torque converter. Then the process bushing cylinder 2 acts, and the process bushing cylinder 2 retracts.

[0039] The process bushing fixture 9 returns to its original position with the removed hydrodynamic torque converter process bushing; at this time, the conveying chute cylinder 13 operates to connect the conveying chute 14 located below the process bushing fixture 9 with the process bushing placement container 4 on the test tray; at this time, the fixture cylinder 11 operates to release the hydrodynamic torque converter process bushing, and the hydrodynamic torque converter process bushing moves downward in a free-fall state. The hydrodynamic torque converter process bushing is conveyed to the process bushing placement container 4 through the conveying chute 14. The conveying chute cylinder 13 returns to its original position after staying for 2 seconds, and the anti-drop cylinder 12 operates to leave the clamped hydrodynamic torque converter and return to its original position; thus far, the hydrodynamic torque converter process bushing is automatically removed by the process bushing conveying device of the present invention and conveyed into the process bushing placement container 4, completing one working cycle.

[0040] The working principle of the process bushing conveying device of the present invention is: the cylinders are controlled by solenoid valves to operate one by one according to a certain logical relationship, enabling the mechanical structures to cooperate with each other to automatically disassemble the hydrodynamic torque converter process bushing used during the automatic transmission test and convey it into the specified process bushing placement container 4, realizing automated production. It is required that the concentricity tolerance between the process bushing fixture 9 and the hydrodynamic torque converter process bushing is within 2 mm, which helps to improve the accuracy of the entire assembly process and facilitates the stable clamping of the hydrodynamic torque converter process bushing by the process bushing fixture 9.

[0041] All cylinders adopted in the present invention are off-the-shelf components.
