Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole instructions and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
Fig. 3 to Fig. 5 shows the structural representation of the detection frock of the injection pump of engine bracket according to the utility model preferred implementation, and it comprises measuring seat 2, clamp system and auxiliary spindle 3.On the engine of the injection pump bracket 1 measured in the present embodiment to be a kind of model being installed on Guangxi Yuchai Machinery Co., Ltd.'s production and selling be C3000.
As shown in Figure 3 and Figure 4, measuring seat 2 is provided with base plate 21 and side plate 22, base plate 21 can be connected by L-shaped shape with side plate 22, side plate 22 is provided with two register pins 23 corresponding with two dowel holes 12 of injection pump bracket 1, is inserted in by two dowel holes 12 when injection pump bracket 1 is installed on side plate 22 and completes location on two register pins 23.Preferably, side plate 22 and base plate 21 are provided with multiple through hole to form engraved structure, thus alleviate the overall weight of frock, easy to use.Clamp system is used for injection pump bracket 1 to be fixed on side plate 22, preferably, clamp system is several lock-screws 24, several lock-screws 24 are each corresponding with the mounting hole 13 of an injection pump bracket 1, the side plate 22 of measuring seat 2 is provided with several locking screw holes, and several locking screw holes are each corresponding with a lock-screw 24.When injection pump bracket 1 is installed on side plate 22, is tightened against on locking screw holes through after mounting hole 13 by lock-screw 24, thus injection pump bracket 1 can be firmly installed on side plate 22.Further preferably, lock-screw 24 is four, and these four lock-screws 24 are corresponding with the mounting hole 13 at four angles up and down of injection pump bracket 1.
