Description

Technical Field

[0002] During the machining process of engine connecting rods, about 30% of the tasks in connecting rod machining need to be completed by machining center equipment, among which rough boring of large and small holes is the bottleneck process. The large holes processed in this process also need to be used as the positioning reference for the subsequent process.

[0003] During processing, the tools need to process the workstations separately. Taking rough boring of large holes as an example, it is necessary to carry out "rough processing → fine processing → chamfering and deburring". A total of three tools are needed and they are processed separately. This not only increases the production cycle, reduces production efficiency, but also increases the tool cost.

[0004] The prior art still has the following deficiencies:

[0005] Excessive design and irrational use of existing processing tools have led to low production line efficiency, long cycle, high cost and other undesirable phenomena, reducing the operating costs of enterprises. Utility Model Content

[0008] Preferably, the second tool assembly also includes a second telescopic cylinder fixedly connected to one side of the two connecting seats; the telescopic ends of the two second telescopic cylinders are detachably fixedly connected to the first slider; and a second tool pocket is opened on one side of the two first sliders.

[0009] Preferably, the second tool assembly further includes a fine boring tool and a chamfering tool respectively installed inside the two second tool pockets.

[0010] Preferably, a driving motor is installed inside each of the two first sliding blocks, and the output ends of the two driving motors are detachably fixedly connected to the fine boring tool and the chamfering tool respectively.

[0011] Preferably, the first tool assembly includes two second sliding blocks detachably fixedly connected to the end of the tool rod, and a third tool pocket is respectively formed at one end of each of the two second sliding blocks which are away from each other.

[0012] Preferably, a roughing knife is detachably and fixedly connected to the inside of each of the two third knife pockets, and a driving device is installed at the tail of the knife rod.

[0013] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0014] By integrating the first tool assembly and the second tool assembly on the same tool bar, the number of tool bars used is reduced, and the company's operating costs are reduced; the frequency of tool changes is reduced, and production efficiency is improved; the tool handle is easy to install and adjust, simple to operate, and has stable quality.
