Abstract
A pair of fastening pinchers for welding assembly of an upper oil tank and a lower oil tank of a transformer in engine of a motor train unit comprises an upper pincher and a lower pincher, wherein two outer pincher ears are arranged on the upper pincher; two inner pincher ears are arranged on the lower pincher; the outer pincher ears of the upper pincher are sleeved outside and connected with the inner pincher ears of the lower pincher through pin shafts to form the pinchers of which the upper pincher and the lower pincher can swing around the pin shafts relatively; a screw hole with a pincher fastening bolt mounted therein is formed at the rear part of the upper pincher; a groove is formed at the rear part of the lower pincher and corresponds to the screw hole at the rear part of the upper pincher; and during pinching, the bottom of the pincher fastening bolt is propped against the groove of the lower pincher. In the fastening pinchers, the upper oil tank and the lower oil tank are pinched under the action of the upper pincher, the lower pincher and the bolt by taking the pin shafts of the fastening pinchers as the center. The fastening pinchers can meet the welding and other assembly requirements of the upper and the lower oil tanks of 200km/h, 300km/h and other shell-type transformers.
Description
Technical field
The utility model relates to a kind of technology and pattern assembly, particularly relates to a kind of fastening hawkbill that is used for lower fuel tank welding general assembly on the EMUs locomotive transformer, is mainly used in the welding general assembly of lower fuel tank on the EMUs locomotive transformer.
Background technology
In China a kind of EMUs locomotive by external introduction is arranged, this kind EMUs locomotive transformer is a shell type transformer, and this kind transformer is the transformer dissimilar with the EMUs locomotive of China.Oil tank of transformer is made up of last lower fuel tank, when oil tank of transformer is installed, need be the assembling benchmark with the lower fuel tank, treat that parts assemblings such as coil, silicon steel sheet insulating part in the fuel tank are intact after, lift top tank and lower fuel tank again to weld; In when welding, also be lined with two circle asbestos cords because go up lower fuel tank by between t=3.2mm steel plate flanging and they, need to clamp and could weld.We do not have the special soldering appliance of this kind now, just utilize common clamp to assist clamping, but it is bad to clamp effect, does not also install, and need a kind of special tooling that is used for EMUs locomotive shell type transformer top tank and lower fuel tank welding of specialized designs for this reason.
The utility model content
The purpose of this utility model is exactly the deficiency at existing EMUs locomotive shell type transformer top tank and lower fuel tank welding tooling, in order to realize the welding general assembly of lower fuel tank on the EMUs locomotive transformer, provide a kind of fastening hawkbill that is used for lower fuel tank welding general assembly on the EMUs locomotive transformer.
The purpose of this utility model is achieved through the following technical solutions, a kind of fastening hawkbill that is used for lower fuel tank welding general assembly on the EMUs locomotive transformer, comprise that is gone up a clamp, a following clamp, Qianer outside two is arranged on last clamp, on the clamp two interior Qianers are being arranged down, the outer Qianer of last clamp is enclosed within down outside the interior Qianer of clamp, and couple together by bearing pin, form one and go up the clamp that clamp and following clamp can be swung around bearing pin mutually; At last clamp rear portion one screw is arranged, be equipped with the clamp trip bolt in the screw; There is a groove at rear portion at following clamp, and groove location is corresponding with last clamp rear portion screwhole position, and when stepping up, the bottom of clamp trip bolt props up down on the groove of clamp.
The beneficial effects of the utility model are: fastening hawkbill is the center with fastening hawkbill bearing pin, and by the effect of upper and lower clamp and bolt, the clamping of lower fuel tank is to guarantee the quality of welding in the realization.Can satisfy the matching requirements such as welding of lower fuel tank on the class shell type transformers such as 200Km/h, 300Km/h.This fastening hawkbill can promote the quality and the production efficiency of lower fuel tank welding on the EMUs transformer greatly.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structural representation vertical view;
Fig. 3 is a work schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment one
As illustrated in fig. 1 and 2, a kind of fastening hawkbill 10 that is used for lower fuel tank welding general assembly on the EMUs locomotive transformer, comprise that is gone up a clamp 1, a following clamp 2, Qianer 7 outside two is arranged on last clamp 1, on the clamp 2 two interior Qianers 6 are being arranged down, the outer Qianer 7 of last clamp is enclosed within down outside the interior Qianer 6 of clamp, and couple together by bearing pin 8, form one and go up the clamp that clamp and following clamp can be swung around bearing pin mutually; At last clamp rear portion 4 screw is arranged, be equipped with clamp trip bolt 3 in the screw; There is a groove 9 at rear portion 5 at following clamp, and groove 9 positions are corresponding with last clamp rear portion 4 screwhole positions, and when stepping up, the bottom of clamp trip bolt 3 props up down on the groove 9 of clamp.
Fig. 3 is a use working state figure of the present utility model, by accompanying drawing as can be seen oil tank of transformer form by last lower fuel tank, with lower fuel tank 12 is the assembling benchmark, treat that parts assemblings such as coil, silicon steel sheet in the fuel tank are intact after, lift top tank 11 and lower fuel tank 12 welding again; Last lower fuel tank is a rectangle, and girth has nearly 3.4 meters, by also being lined with two circle asbestos cords, welding again after need clamping simultaneously with more than 20 clamping hawkbills 10 between t=3.2mm steel plate flanging 13 and the last lower fuel tank.The function that clamps hawkbill 10 has satisfied the quality and the manufacturing schedule of lower fuel tank welding on the EMUs transformer fully.
Claims (2)
1. fastening hawkbill that is used for the welding of lower fuel tank on EMUs locomotive transformer general assembly, it is characterized in that: comprise that is gone up a clamp, a following clamp, Qianer outside two is arranged on last clamp, on the clamp two interior Qianers are being arranged down, the outer Qianer of last clamp is enclosed within down outside the interior Qianer of clamp, and couples together by bearing pin, forms the clamp that a last clamp and following clamp can be swung around bearing pin mutually; At last clamp rear portion one screw is arranged, be equipped with the clamp trip bolt in the screw.
2. the fastening hawkbill that is used for lower fuel tank welding general assembly on the EMUs locomotive transformer as claimed in claim 1, it is characterized in that: there is a groove at the rear portion at following clamp, groove location is corresponding with last clamp rear portion screwhole position, when stepping up, the bottom of clamp trip bolt props up down on the groove of clamp.
