Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole description and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
As shown in Figure 1, the electrolysis that prevents according to the specific embodiment of the invention is burnt specifically the comprising of frock of cylinder block dowel hole: frock insulation board 1, frock conductive plate 2, insulating flange 3, alignment pin 4 and conduction locating piece 7, wherein, frock conductive plate 2 is arranged on the end face of frock insulation board 1, alignment pin 4 is arranged on the end face of frock conductive plate 2 by insulating flange 3, pin-and-hole 5 for inserting cylinder block 6 positions the cylinder block 6 be supported on conduction locating piece 7, this prevents the alignment pin 4 of the frock of electrolysis burn cylinder block dowel hole to be arranged on the end face of frock conductive plate 2 by insulating flange 3, for the insulation of alignment pin, the electric current produced in electrolytic process is not contacted with pin-and-hole wall by alignment pin, thus prevent because the transmission of electric current makes the slight gap of alignment pin and pin-and-hole wall produce and burns, improve the quality of processing, reduce the percent defective of cylinder block, electrowinning process energy continuous and effective is carried out.
Frock insulation board 1 is positioned at the whole bottom surface preventing the frock of electrolysis burn cylinder block dowel hole, for supporting tool conductive plate 2, insulating flange 3, alignment pin 4 and conduction locating piece 7, and for the whole insulation preventing the frock of electrolysis burn cylinder block dowel hole in electrolytic process.
Frock conductive plate 2 is arranged on the end face of frock insulation board 1, and it offers the resigning hole of insulating flange 3, and the outer circumference of this resigning hole evenly offers flange and installs screwed hole, for coordinating fixed insulation flange 3 with the construction bolt of insulating flange 3.The side of frock conductive plate 2 is provided with current output terminal 8, for Faradaic current being derived the frock preventing electrolysis burn cylinder block dowel hole, forms galvanic circle.
Conduction locating piece 7 is arranged on the end face of frock conductive plate 2, for supporting cylinder block 6.
As shown in Figure 3 and Figure 4, the middle part of insulating flange 3 offers dowel hole 31, and the outer circumference of this dowel hole 31 offers multiple flange mounting hole 32, for the construction bolt by insulating flange 3, insulating flange 3 is fixed to the end face of frock conductive plate 2.Preferably, flange mounting hole is uniform along the outer circumference of dowel hole 31, and flange mounting hole is four.Flange mounting hole is counterbore, and the construction bolt head of insulating flange 3 can sink to this flange mounting hole, prevents the construction bolt head of insulating flange 3 and cylinder block 6 from interfering.The bottom of insulating flange 3 has the insertion section with the resigning hole adaptation of the insulating flange on frock conductive plate.
As shown in Figure 5, alignment pin 4 comprises: positioning head 41 and bar portion 42, and this bar portion comprises: the polished rod be connected with positioning head and the threaded rod being positioned at bar portion end, positioning head 41 is located for coordinating with the pin-and-hole 5 of cylinder block 6.During installation, as shown in Figure 2, alignment pin 4 inserts the dowel hole 31 of insulating flange 3 by bar portion 42, and the threaded rod of bar portion end is stretched out the dowel hole 31 of insulating flange 3 and fixed by nut.
During electrolysis: first and frock conductive plate 2 be arranged on frock insulation board 1, alignment pin 4 and insulating flange 3 fit through screw thread and tighten, then are arranged on frock conductive plate 2 by bolt; Then, cylinder block 6 is placed on the conduction locating piece 7 of frock conductive plate 2, locates to cylinder block 6, finally carry out electrolysis by pin-and-hole 5 and alignment pin 4.In electrolytic process, the burn of cylinder block dowel hole often can be caused at traditional positioner; and designed this positioner directly can break and leads to the electric current of alignment pin; alignment pin was protected with coordinating of cylinder block pin-and-hole, prevents Workpiece fixing pin-and-hole from burning.
