Description

Technical Field

[0001] The present invention relates to the field of machining, and in particular to a slag cleaning device for an automotive flywheel ring gear. Background Art

[0002] The flywheel ring gear assembly is a connecting part that transmits the power of the starter to the crankshaft. Its main function is to achieve power transmission between the starter and the crankshaft. The flywheel ring gear is a ring-shaped workpiece, and its initial processing is completed by butt welding. After the flywheel ring gear is welded, the slag at the welding joint needs to be cleaned. With the rapid development of the automotive industry, the demand for ring gears is huge. The original cleaning equipment is relatively backward, with slow cleaning speed, low accuracy, instability, and it cannot meet the requirements of subsequent processing, so manual cleaning by personnel is still required, resulting in high labor intensity. In addition, the bed body stiffness of the existing equipment is low, and the workbench bracket deforms severely during use; the sliding of the sliding table is a guide post and guide seat structure with too large a gap, resulting in low machining accuracy; the hydraulic system design is unreasonable, the clamping force of the workpiece cannot be maintained, and the walking speed of the sliding table is slow; the tool bar is a rigid structure, and there is no tool retraction when the tool is out, scraping the workpiece, increasing the clamping difficulty, and the machining is extremely unstable, with serious blade wear; there is no precise tool setting function, and precise tool setting cannot be achieved during work.

[0003] Therefore, there is an urgent need for a slag cleaning device for an automotive flywheel ring gear, which can clean the formed slag at one time after the circular welding of the automotive flywheel ring gear, solve the problems for subsequent processing, and can solve the problems of slow speed, low accuracy, instability, and high labor intensity of the original cleaning equipment.

[0038] Embodiment:

[0039] As Figure 8 shown, place the annular workpiece 42 on the upper surface of the guide seat 18, make the inner ring of the workpiece 42 fit the positioning block 21, control the hydraulic station to inject oil into the clamping cylinder 19.

When cutting the workpiece 42, the driving end of the hydraulic cylinder 7 drives the cutting device to reciprocate, the transverse feed mechanism reciprocates horizontally, and the longitudinal feed mechanism reciprocates vertically, so as to drive the cutting device to cut the workpiece 42. Since the induction block 40 is provided on the slide rail 6 and the proximity switch 39 is provided on the slide rail seat 5, the transverse feed mechanism and the longitudinal feed mechanism will not have the phenomenon of excessive feed. The air inlet 30 of the adjustable tool bar one 11 is connected to compressed air, and while cutting, the welding slag is blown along the through hole 34 into the slag guide groove 35 and into the slag box 36.

When retracting the tool, the tool body 13 will have a slight rotational movement under the action of force, making the blade 14 slightly lift from the workpiece 42 and not scrape the workpiece 42. After all the tool retractions are completed, make the driving end of the clamping cylinder 19 rise, the clamping jaw 20 release the workpiece 42, and unload the workpiece 42. The present invention is applicable to the cleaning of welding slag of annular workpieces 42 of different sizes, and only needs to adjust the tool and replace the cutting blades 14 of different sizes before processing.
