Description

Technical Field

[0001] The utility model relates to a clamping device for machining an automobile gearbox, belonging to the technical field of machining fixtures for gearboxes. Background Technique

[0002] The gearbox is a mechanism used to change the rotational speed and torque from the engine. It can fix or shift gears to change the transmission ratio between the output shaft and the input shaft. The transmission consists of a transmission mechanism and a control mechanism. Some automobiles also have a power take-off mechanism. During the machining process of an automobile gearbox, a clamping device is required.

[0003] According to the clamping device for machining an automobile gearbox provided by the publication number CN218169502U, which relates to the technical field of workbench fixtures. The clamping device for machining an automobile gearbox includes a machine tool body. A collection box is fixedly connected to the machine tool body. A rotating shaft is rotatably connected to the collection box through a bearing. By setting the cooperation of the collection box, the rotating shaft, the placement plate, the clamping mechanism, the gear, the first telescopic driving device, the transmission frame and the rack, after the workpiece is machined and taken out, the first telescopic driving device is controlled to drive two racks to move through the transmission frame. The movement of the two racks drives two gears to rotate through meshing with the two gears. The rotation of the two gears drives the rotating shaft to rotate. The rotation of the rotating shaft drives the placement plate to rotate so that the clamping mechanism faces downwards. The debris on the clamping mechanism will fall off the clamping mechanism under the action of gravity and fall into the collection box for collection. Then, the placement plate is controlled to reset, effectively avoiding the influence of debris on the clamping of the next workpiece by the fixture, improving the convenience of debris cleaning and the work efficiency. When the above device clamps the gearbox, it cannot adjust the center point position after the gearbox is clamped. At the same time, after a workpiece is machined, the workpiece needs to be taken out and the device needs to be cleaned before the next feeding and machining can be continued, resulting in a low production efficiency of the device and thus a low practicality of the device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a clamping device for machining an automobile gearbox. The utility model can conveniently adjust the positioning center position of the workpiece, and at the same time facilitate the loading and unloading and the cleaning of the workbench during the machining of the gearbox, thereby effectively improving the production efficiency and practicality of the device, so as to solve the problems raised in the above background technique.
