Abstract
The utility model relates to a locating fastener special for die-filling of a lug plate. The locating fastener special for the die-filling of the lug plate is characterized by comprising a cylindrical connecting bar and a head portion which is fixed on the end portion of the connecting bar and used for rotating the connecting bar. A pouring die matched part and a lug plate matched part are sequentially arranged on the connecting bar and from the end where the head portion is fixed. An outer thread is arranged on the lug plate matched part. The diameter of the lug plate matched part is smaller than the diameter of the pouring die matched part. The locating fastener special for the die-filling of the lug plate has the advantages of being simple in structure, convenient to use and capable of enabling a pouring die and the lug plate to be reliably and accurately connected, and therefore unnecessary workload conducted due to installation error is reduced.
Description
Technical field
The utility model relates to the location fastening piece that a kind of mutual inductor cast lug plate mould is used.
Background technique
Some transformer requests are fixed several lug plates inside casting mold, lug plate is provided with screw, has circular hole on casting mold, and hexagon head bolt passes the circular hole on casting mold, its end coordinates with screw on lug plate, with this, lug plate is fixed in casting mold.
At present, transformer request is fixing 6-7 lug plate in casting mold the inside, and lug plate is provided with M
6 screw has ￠ 6.2 circular holes on casting mold, use the M6 hexagon head bolt to pass ￠ 6.2 circular holes on casting mold, and coordinates with M6 screw on lug plate, and lug plate is fixed in casting mold.
Under certain situation, screwhole diameter on lug plate is less than Circularhole diameter on casting mold, as: some lug plates are provided with the screw of M5, because 6.2 Circularhole diameters of the ￠ on casting mold are immutable, when adopting traditional M5 bolt that casting mold is connected with lug plate, have very large gap between ￠ 6.2 circular holes of bolt and casting mold, the relative position of bolt is difficult for definite, and the centre distance of several screws is difficult to guarantee.In addition, for the casting quality that guarantees casting mold has been convenient to install, necessarily require screw rod to exceed plane 5mm on lug plate, at present, this highly need to fill mould personnel range estimation, locks afterwards the nut of casting mold circular hole lower plane again, control not accurate enough in case screw rod exceeds the height on plane on lug plate, need the assembly crewman to carry out a large amount of follow-up adjustment processing works, increased the unnecessary workload of assembly crewman, when having extended the rigger.
Summary of the invention
The utility model for solve the technical problem that exists in known technology provide a kind of simple in structure, easy to use, can make casting mold reliable with lug plate and accurately is connected, thereby fastening piece is located in the wiring mould special use on chip of the unnecessary workload that minimizing is carried out because of alignment error.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the special-purpose fastening piece of locating of a kind of wiring mould on chip, comprise cylindrical connecting rod and be fixed on the head that described interlinking lever end is used for the rotation connecting rod, on described connecting rod, an end of self-retaining head is provided with casting mold auxiliary section and lug plate auxiliary section successively, described lug plate auxiliary section is provided with outside thread, and the diameter of described lug plate auxiliary section is less than the diameter of described casting mold auxiliary section.
The utility model can also adopt following technological scheme:
Head near described connecting rod on described casting mold auxiliary section is provided with the screw section, equipped nut on described screw section.
The diameter of described casting mold auxiliary section is ￠ 6.1, and the diameter of described lug plate auxiliary section is 5mm, and the length of described lug plate auxiliary section is 10mm.
The utility model is compared advantage and the good effect that conventional art has:
1. has the casting mold auxiliary section that coordinates with the circular hole of casting mold specially on the connecting rod of location fastening piece, the casting mold auxiliary section can with casting mold on circular hole gap reasonable coordination, the position of connecting rod is accurately limited, can guarantee the centre distance of several screw rods, improve the installation precision of lug plate.
2. the diameter of lug plate auxiliary section is less than the diameter of casting mold auxiliary section, make the transition position of lug plate auxiliary section and casting mold auxiliary section form shoulder, this shoulder can limit the length that the lug plate upper surface is stretched out in the connecting rod end, remove the personnel's range estimation of dress mould from or measure, having improved dress mould accuracy and efficiency.

In figure: 1, connecting rod; 1-1, casting mold auxiliary section; 1-2, lug plate auxiliary section; 1-3, screw section; 2, head; 3, nut; 4, casting mold; 5, lug plate.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See also Fig. 1, the special-purpose fastening piece of locating of a kind of wiring mould on chip.Comprise cylindrical connecting rod 1 and be fixed on described connecting rod 1 end head 2, wherein head 2 is hexagon nuts, in order to the bar 1 that is rotatably connected.On connecting rod 1, an end of self-retaining head 2 is provided with casting mold auxiliary section 1-1 and lug plate auxiliary section 1-2 successively, and lug plate auxiliary section 1-2 is provided with outside thread, and the diameter of lug plate auxiliary section 1-2 is less than the diameter of casting mold auxiliary section 1-1.1-1 upper head 2 near connecting rod 1 in casting mold auxiliary section is provided with screw section 1-3, the upper equipped nut 3 of screw section 1-3.
As Fig. 2, in the present embodiment, the diameter of casting mold auxiliary section 1-1 is ￠ 6.1, it coordinates with the circular hole of ￠ 6.1 on casting mold 4, the diameter of lug plate auxiliary section 1-2 is 5mm, coordinates with the tapped hole of M5 on lug plate 5, and the length of lug plate auxiliary section 1-2 is 10mm.
Guarantee 2mm in the minimum circular hole that can enter casting mold 4 of the screw section 1-3 of connecting rod 1, so that nut can be sturdy with the lower plane of casting mold 4, be adjacent to.
