Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing:

[0014] Such as figure 1 As shown, the crankshaft unilateral fillet rolling auxiliary device of the present invention includes a connecting bracket 2 and a single-wheel rolling head 8, one end of the connecting bracket 2 is provided with a connecting hole, and the other end is provided with an adjusting screw sleeve 4, and the single-wheel rolling A roller 9 is set at the bottom corner position of one end of the head 8, and an adjusting bolt 6 is set at the other end corresponding to the adjusting screw sleeve 4. The connecting hole is set as a threaded hole, and a connecting piece 3 with an external thread is arranged in the threaded hole. The connecting bracket 2 is arranged in a U shape, and its open end is arranged downward. The single-wheel rolling head 8 includes a rolling body, a roller 9 is arranged at the lower left corner of the rolling body, and a pressing plate...

Abstract

The invention is mainly applied to the technical field of diesel engine component machining and particularly relates to an auxiliary device for unilateral fillet rolling of a bent axle. The device comprises a connecting support and a single-wheel rolling head. Connecting holes are formed at one end of the connecting support, and an adjustment thread sleeve is arranged at the other end of the connecting support. A roller is arranged at the position of a base angle of one end of the single-wheel rolling head, and an adjustment bolt is arranged at the other end of the single-wheel rolling head ina manner that the adjustment bolt is corresponding to the adjustment thread sleeve. According to the auxiliary device for unilateral fillet rolling of the bent axle, rolling force can be disintegrated; and the problem of uneven force bearing is solved. By means of the device, the problem that rolling cannot be conducted on unilateral fillets of two ends of the bent axle can be solved; thus filletrolling of each portion of the bent axle is completed more comprehensively; and integral performance of the bent axle is improved. The structure is simple and reasonable; and the device is easy to use.

Description

technical field [0001] The invention relates to a crankshaft one-side fillet rolling auxiliary device, which is mainly used in the technical field of diesel engine parts processing. Background technique [0002] Crankshaft fillet rolling strengthening technology has been widely used on diesel engine crankshafts, especially for vehicle crankshafts, in order to improve its performance and fatigue strength, rolling process is often added; for the journal fillet between two crank arms, because there are crank arms As a support, its force is relatively uniform; due to design requirements, the driving end and free end of the crankshaft often encounter the situation that only one side of the main journal needs to be rounded. If the force cannot be supported, this will lead to uneven rolling force, and the fillet rolling at this position cannot be performed. At present, some crankshaft processing enterprises adopt the design scheme of extending the indenter to support the flanges a...
