Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1, the positioning device for chamfering an automobile sensor heat dissipation assembly according to the embodiment includes a positioning element and a pressing element, wherein the positioning element and the pressing element are matched to position parts stacked in sequence from front to back to form a whole; the positioning piece comprises a step positioning block 7 and a front positioning block 5, a plurality of step surfaces 701 with different heights are formed on the top surface of the step positioning block 7, and the step surfaces 701 are respectively used for positioning the bottoms of all parts to enable the tops of all parts to be different in height; the front positioning block 5 is arranged at the rear part of the step positioning block 7 and is used for positioning the front side surface of the foremost part; the pressing part comprises a movable pressing head 3, and the movable pressing head 3 is used for pressing and positioning the rear side face of the part on the rearmost side.

Fig. 2 is a schematic structural diagram of the above embodiment in an operating state. The part to be processed is groove aluminum 9, and the groove aluminum 9 can be used as a shell of a heat radiator of some vehicle-mounted sensors or a shell of a heat exchange system on a large diesel engine. As shown in fig. 3, the channel aluminum 9 is a bent shell, and the channel aluminum 9 can be stacked at a time to form a whole structure as shown in fig. 2.

Preferably, the step surface 701 is sequentially lowered from front to back, so that the top heights of the parts are sequentially lowered.

Specifically, the bottom end surface 902 of each channel aluminum 9 is placed on the step surface 701 from front to back in sequence, so that the height of the top end surface 903 of each channel aluminum 9 decreases in sequence. The top end surface 903 is conveniently chamfered, and a chamfered surface 904 shown in fig. 5 and 6 is machined. As shown in fig. 4, in the machining process, the inner side surface of the most front channel aluminum 9 is pressed against and positioned by the front positioning block 5, and the outer side surface 901 of the most rear channel aluminum 9 is pressed against and positioned by the movable ram 3.
