Abstract

The utility model relates to the technical field of auxiliary tools used for welding and fixing PINs and discloses a PIN welding auxiliary jig. The PIN welding auxiliary jig comprises a jig base body. A boss is arranged on the upper portion of the jig base body. A welding work board is arranged at one side of the boss of the jig base body. A cavity is formed in the lower portion of the jig base body. A sealing board is arranged on an opening of the cavity. Multiple through holes matched with PINs in size are formed in the boss. First clamping grooves corresponding to the through holes are further formed in the boss. Second clamping grooves corresponding to the first clamping grooves are formed in the welding work board. A storage battery and an electromagnet are arranged in the cavity of the jig base body. The storage battery is electrically connected with the electromagnet. A line passing hole communicated with the cavity is formed in the side wall of the jig base body. The jig base body is matched with the welding work board so that multiple PIN locating grooves can be formed and the PINs can be located. Power is supplied to the electromagnet through the storage battery, so that one end of each PIN is attracted, and therefore each PIN does not swing under the action of external force at this time.

Description

A kind of PIN pin welding auxiliary fixture

Technical field

The utility model relates to the aid technical field being welded and fixed for PIN pin, is specifically related to a kind of PIN pin welding auxiliary fixture.

Background technology

When PIN pin is now located fixedly by welding procedure, usually because the position location being welded and fixed selection is improper, cause the undercut, the overlap that occur between PIN pin and connector, burn and the defect such as pit (indent), affect the fixed effect between PIN pin and connector, be prone to the situation of fracture in the short time, when there is fracture, need to again be welded and fixed, take a lot of work and mistake.

Utility model content

For solving the problems of the technologies described above, we have proposed a kind of PIN pin welding auxiliary fixture, its object: welding position is unified, and welding job plate is replaceable.

For achieving the above object, the technical solution of the utility model is as follows:

A pin welding auxiliary fixture, comprises tool matrix, and the top of tool matrix is provided with boss, and a side of the boss of tool matrix is provided with welding job plate, and the bottom of tool matrix is provided with cavity, and the open ports of described cavity is provided with sealing plate;

Described boss is provided with a plurality of through holes that match with size PIN pin, and boss is also provided with first draw-in groove corresponding with through hole, and welding job plate is provided with second draw-in groove corresponding with the first draw-in groove;

In the cavity of tool matrix, be provided with battery and electromagnet, battery and electromagnet are electrically connected to, and the sidewall of tool matrix is provided with the through wires hole being connected with cavity.

Preferably, electromagnet is DC electromagnet.

Preferably, the material of electromagnet armature is ingot iron.

Preferably, welding job plate and tool matrix are bolted.

Preferably, the quantity of through hole is five.

Pass through technique scheme, tool matrix with formed a plurality of PIN pin locating slots coordinating of welding job plate PIN pin located, by battery, to electromagnet, switch on again, held one end of PIN pin, now PIN pin is subject to external force and also can rock, the other end of PIN pin protrudes from boss, and welding position is unified, has facilitated follow-up being welded and fixed between PIN pin and connector; When welding job plate arrives operating limit, can be dismantled replacement.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structural representation of a kind of PIN pin welding auxiliary fixture disclosed in the utility model;

Fig. 2 is the schematic top plan view of a kind of PIN pin welding auxiliary fixture disclosed in the utility model.

Numeral and the represented corresponding component title of letter in figure:

1. tool matrix 11. boss 111. through hole 112. first draw-in groove 12. through wires hole 2. welding job plate 21. second draw-in groove 3. sealing plate 4. battery 5. electromagnet

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Below in conjunction with schematic diagram, the specific embodiment of the present utility model is described in further detail.

As depicted in figs. 1 and 2, a kind of PIN pin welding auxiliary fixture, comprises tool matrix 1, the top of tool matrix 1 is provided with boss 11, one side of the boss 11 of tool matrix 1 is provided with welding job plate 2, and the bottom of tool matrix 1 is provided with cavity, and the open ports of described cavity is provided with sealing plate 3;

Boss 11 is provided with the through hole 111 that five sizes with PIN pin match, and boss 11 is also provided with first draw-in groove 112 corresponding with through hole 111, and welding job plate 2 is provided with second draw-in groove 21 corresponding with the first draw-in groove 112;

In the cavity of tool matrix 1, be provided with battery 4 and electromagnet 5, battery 4 and electromagnet 5 are electrically connected to.

Tool matrix 1 with formed five PIN pin locating slots coordinating of welding job plate 2 PIN pin located, by battery 4, give electromagnet 5 energisings again, held one end of PIN pin, now PIN pin is subject to external force and also can rock, the other end of PIN pin protrudes from boss 11, welding position is unified, has facilitated follow-up being welded and fixed between PIN pin and connector; When welding job plate 2 arrives operating limit, can be dismantled replacement.

The sidewall of tool matrix 1 is provided with the through wires hole 12 being connected with cavity, convenient power control switch and the charging port installed.
