Abstract

The utility model relates to a fixture used for assembling electromagnet of a transformer, which comprises a first clamping block and a second clamping block. One end of the first clamping block is connected with one end of the second clamping block through corresponding pins, the first clamping block and the second clamping block are in movable pilot fit with the pins along the axial direction of the pins, arc clamping openings are correspondingly arranged one side of the first clamping block close to the second clamping block and one side of the second clamping block close to the first clamping block respectively along the axial direction of the pins, step faces used for being clamped with opening edges of jaws of a bench clamp are arranged on one side of the first clamping block away from the second clamping block and one side of the second clamping block away from the first clamping block. As the arc clamping openings are correspondingly arranged on the first clamping block and the second clamping block respectively, partial contact stress between the clamping and a collision rod is reduced and the collision rod cannot be damaged due to clamping. Furthermore, work efficiency is improved since the first clamping block and the second clamping block can be matched with the bench clamp. The collision rod of the fixture can be prevented from being damaged due to clamping, the fixture can be operated by a single person, and the problem that a locknut on the collision rod of the electromagnet is difficult to be mounted in the assembling process of the electromagnet is solved generally.

Description

A kind of anchor clamps that are used for the assembling of transformer electromagnet

Technical field

The utility model relates to the electromagnet assembling aid in the transformer, especially a kind of anchor clamps that are used for the assembling of transformer electromagnet.

Background technology

Electromagnet is one of indispensable part in the present transformer, in the assembling process of electromagnet, need locking nut be set at an end of its electromagnet lance, and because the outline of electromagnet lance be circular, thus the installation of locking nut comparatively difficult; Specifically, i.e. clamping to the electromagnet lance is relatively more difficult, if only directly clamp with bench vice, well-known, bench vice jaw place is a flat grip mouth, if the electromagnet lance is directly fixed on the jaw place, lance is then very easily crushed and lost efficacy; As clamping, then need two staff to operate simultaneously at least, and the efficient that wastes time and energy is extremely low by pliers.

Summary of the invention

The purpose of this utility model is to provide a kind of anchor clamps that are used for the assembling of transformer electromagnet, to solve the problem of the installation of the locking nut on electromagnet lance difficulty in the electromagnet assembling process.

In order to address the above problem, the anchor clamps that are used for transformer electromagnet assembling of the present utility model are by the following technical solutions: a kind of anchor clamps that are used for the assembling of transformer electromagnet, comprise first fixture block and second fixture block, described first, the two ends of second fixture block connect by corresponding bearing pin respectively, first, second fixture block is axially cooperating with the bearing pin activity-oriented along bearing pin respectively, two fixture blocks are provided with the corresponding arc clamp port that be used for clamping lance on the side adjacent to each other at described bearing pin on axially, are respectively arranged with on the two fixture blocks side away from each other to be used for the step surface of joining along card with the mouth of bench vice jaw.

Described clamp port is semicircle.

Be arranged with back-moving spring respectively on described two bearing pins, described each back-moving spring all is mounted between first, second fixture block.

Because the anchor clamps that are used for the assembling of transformer electromagnet of the present utility model are provided with corresponding arc clamp port respectively on its first, second fixture block, like this can well be suitable with the profile of the lance of electromagnet, increased the contact area of anchor clamps and lance, reduce the local contact stress between anchor clamps and the lance, solved the problem that causes lance to crush with bench vice clamping lance owing to directly; In addition, be used for the step surface of joining, can be used, therefore only need a people just can operate, also improved operating efficiency when having reduced labour cost with bench vice with the bench vice card owing to be respectively arranged with on two fixture blocks; But anchor clamps of the present utility model can prevent to crush lance and one man operation, have solved the problem of the installation of the locking nut on electromagnet lance difficulty in the electromagnet assembling process on the whole.

Further, top dress back-moving spring between described two fixture blocks can automatically spring open two fixture blocks after each the use, and the staff's who further reduces labour intensity has also improved last product efficient on the other hand on the one hand.

Description of drawings

Fig. 1 is the user mode figure (band office is cutd open) of the embodiment 1 of the anchor clamps that are used for transformer electromagnet assembling of the present utility model;

Fig. 2 is the vertical view after Fig. 1 removes lance.

Embodiment

The embodiment 1 that is used for the anchor clamps of transformer electromagnet assembling of the present utility model is shown in Fig. 1-2, by first fixture block 1, second fixture block 2, be used to connect two bearing pins 3 of two fixture blocks and the back-moving spring 4 that is mounted between two fixture blocks is formed.First, the two ends of second fixture block connect by bearing pin 3 respectively, two fixture blocks all bearing pin 3 axially on cooperate with bearing pin 3 activity-orienteds, be arranged with back-moving spring 4 respectively on two bearing pins 3, back-moving spring 4 is mounted between two fixture blocks, back-moving spring 4 is used for automatically springing open two fixture blocks after assembling finishes to workpiece, convenient use next time, also alleviated simultaneously staff's labour intensity, first, second fixture block bearing pin 3 axially on the side adjacent to each other respectively correspondence be provided with semicircular clamp port 5, clamp port 5 is used to put into and clamps electromagnet lance 6, because clamp port 5 is semicircle, therefore suitable with the outline of lance 6, can increase the contact area with lance 6, the local stress when reducing clamp port 5 and clamping lances 6 avoids lance 6 to be crushed; Two fixture blocks bearing pin 3 axially on mutually back to a side on be respectively arranged with and be used for the step surface of joining along card with the jaw mouth of bench vice.The anchor clamps that are used for transformer electromagnet assembling of the present utility model in use, at first described anchor clamps are positioned over the jaw place of bench vice, two fixture blocks are joined along card by the jaw mouth of its corresponding step surface and bench vice respectively, then lance 6 is positioned between the clamp port of two fixture blocks, can carries out the nut assembling after by the turn bench vice push rod being clamped; After assembling finished, the turn bench vice unclamped two fixture blocks, and two fixture blocks separate under the effect of back-moving spring automatically, can take out lance 6, put into next lance then and proceeded assembling, so circulation.

In the foregoing description, the shape of described clamp port 5 can also be other arc except that semicircle, and described back-moving spring 4 can also omit.

Claims

1. one kind is used for the anchor clamps that the transformer electromagnet assembles, it is characterized in that: comprise first fixture block and second fixture block, the two ends of described first, second fixture block connect by corresponding bearing pin respectively, first, second fixture block is axially cooperating with the bearing pin activity-oriented along bearing pin respectively, two fixture blocks are provided with the corresponding arc clamp port that be used for clamping lance on the side adjacent to each other at described bearing pin on axially, are respectively arranged with on the two fixture blocks side away from each other to be used for the step surface of joining along card with the mouth of bench vice jaw.
