Specific embodiment
Embodiments of the present invention will be further described with reference to the accompanying drawing.
Fig. 2 referring to Fig.1, a kind of drum brake bottom plate hole processing clamp, including pedestal 1, are set on the pedestal 1
The power device 7 of fixture assembly and the control fixture assembly, the power device 7 is set in the pedestal 1, in this hair
In bright, power device can be hydraulic device or pneumatic shuttle etc., and the state of pull rod 6 is controlled using included piston rod.Institute
Fixture assembly is stated to include the support 2 being set on the pedestal 1, the fixed plate 3 being set on the support 2 and be set to institute
The backing plate 4 in fixed plate 3 is stated, fixed plate 3 is for support 2 and backing plate 4 to be fixed；The pedestal 1, support 2, fixed plate 3
And between backing plate 4 be to be fixedly connected, the fixture assembly further include the pressing plate 5 being detachably arranged and with the pressing plate 5
The pull rod 6 of cooperation, the pull rod 6 are connect through the fixture assembly with the power device 7, and power device 7 can pass through pull rod 6
It exerts a force to pressing plate 5.
Referring to Fig. 4, specifically, the pull rod 6 includes the body of rod 62 and the briquetting 61 for being set to described 62 one end of the body of rod, institute
The side for stating pressing plate 5 offers the side port 53 cooperated with the briquetting 61.
As preferable embodiment, the briquetting 61 and the side port 53 are rectangle, as shown in figure 5, working as the briquetting
When 61 long side is parallel with the long side of the side port 53, the briquetting 61 acts on 5 infinite place of pressing plate, can take out at this time
Pressing plate 5；When the long side of the long side of the briquetting 61 and the side port 53 is not parallel, the briquetting 61 is limited to the pressing plate 5
Position effect.Referring to Fig. 6, when the long side of briquetting 61 is vertical with the long side of side port 53, briquetting 61 blocks pressing plate 5, to the formation of pressing plate 5
Position-limiting action；Referring to Fig. 7, when angle when the long side angle of the long side of briquetting 61 and side port 53 is any non-parallel, briquetting
61 equally form position-limiting action to pressing plate 5.In position-limiting action, power is provided by power device 7, pull rod 6 is pulled down, is led to
The briquetting 61 crossed on pull rod 6 forms a downward extruding force to pressing plate 5.
Referring to Fig. 3, the pressing plate 5 includes plate body 51 and the limit pressure head 52 that extends along 51 both ends of plate body, and two
The limit pressure head 52 is for fixing drum brake bottom plate to be processed.In conjunction with Fig. 8, required processing on the bottom plate to be processed
Position is axis hole 9 and two mounting holes 10, there is support plate 7 and card slot 8 on the bottom plate, and support plate 7 and card slot 8 are in axis hole 9
