Abstract

The utility model relates to a thermal battery pile assembling rack comprising a lower pressing plate, a pile, an upper pressing plate and four screw rods which are arranged from bottom to top, wherein the four screw rods are vertically connected between the upper pressing plate and the lower pressing plate, and the thermal battery pile assembling rack is characterized in that a rectangular hole is radially arranged in a screw rod main body; one end of the screw rod is outer threads; and the outer thread end of the screw rod is provided with a semi-open slot which is communicated with the rectangular hole. As the rectangular hole and the semi-open slot communicated with the rectangular hole are arranged on the screw rod of the assembling rack to be used as the space for specially containing a lead and outwards leading the lead, the safety of a battery is ensured, and the original volume of the battery is maintained; the adoption of the assembling rack fixed by the four screw rods and the threads ensures that the pile keeps vertical during the assembling process, can conveniently adjust the space between the upper pressing plate and the lower pressing plate of the fastener according to the height of the pile, improves the working efficiency of the battery, lowers the manufacturing cost of the battery, and can meet the requirements of the thermal batteries with different diameters and height.

Description

A kind of thermal cell pile assembly fixture

Technical field

The utility model belongs to the thermal cell technical field of structures, especially relates to a kind of thermal cell pile assembly fixture.

Background technology

Thermal cell electric pile structure frame comprises the fastening frame that top board, lower platen, bracket constitute at present, is used to pile up a plurality of cells of isolating through insulation assembly.The endurance environment capacity of this structure-steel framing is less, is applicable to the thermal cell that the pile height is less.

Along with thermal cell constantly bring forth new ideas, develop and ripe, the kind of pile assembling is more and more, tradition, simple assembly fixture do not reserve the space of special placement lead-in wire; The position was unfixing when battery lead distributed, especially for multichannel output, the battery that the pile multiple spot is fastening; On the cylinder radial circumference; Pile anodal tap of when assembling and negative pole tap all inevitably with some screw rod end close of assembly fixture, the positive and negative electrode tap is easy to cause short circuit with fastening frame because of extruding like this, the bracket in the also easy and fastening frame of the ceiling of positive and negative electrode superposes; Make pile be difficult to into shell, and danger close.Pile is difficult to keep vertical relatively in assembling process simultaneously, needs special-purpose frock clamp just can operate when causing manufacture batteries, has increased manufacture difficulty, the reduction operating efficiency of thermal cell.

Summary of the invention

The utility model provides a kind of guaranteed cell safety and a kind of thermal cell pile assembly fixture easy to make for solving the technical problem that exists in the known technology.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of thermal cell pile assembly fixture comprises from bottom to top lower platen, pile, top board, and is vertically connected at four screw rods between the upper and lower pressing plate, is characterized in: radially be equipped with a rectangular opening on the screw rod main body of said screw rod; Screw rod one end is an external screw thread, and the male end that is positioned at screw rod is equipped with a semi-open slot that communicates with rectangular opening.

The utility model can also adopt following technical scheme:

Said rectangular opening is through hole or blind hole.

Advantage and the good effect that the utlity model has are:

1, the utility model is owing to the semi-open slot of on the screw rod of assembly fixture, producing rectangular opening and communicating with rectangular opening is placed the space that goes between and outwards draw lead-in wire as being exclusively used in; The short circuit of having avoided the positive and negative electrode tap to cause because of extruding; Guarantee the fail safe of battery, and kept the original volume of battery.

2, the utility model adopts four screw rods and the fixing assembly fixture mode of screw thread; Can guarantee that pile keeps vertical in assembling process; Can regulate the distance between the upper and lower pressing plate of fastening frame easily according to the pile height again, need not the making that frock clamp can be accomplished battery, improve the operating efficiency that battery is made; Reduce production cost of cells, can satisfy the needs of different-diameter and height thermal cell.

Embodiment

For further understanding summary of the invention, characteristics and the effect of the utility model, enumerate following examples now, and conjunction with figs. specifies as follows:

With reference to accompanying drawing 1-Fig. 6: a kind of thermal cell pile assembly fixture comprises from bottom to top lower platen 1, pile 9, top board 2, and is vertically connected at four screw rods 3 between the upper and lower pressing plate.

The innovative point of the utility model is: radially be equipped with a rectangular opening 5 on the screw rod main body 4 of said screw rod, said rectangular opening is through hole or blind hole; Screw rod one end is an external screw thread 6, and the male end that is positioned at screw rod is equipped with a semi-open slot that communicates with rectangular opening 7, and screw rod is installed on the top board through external screw thread and nut 8; Screw rod is that interference fits is connected with lower platen.

The manufacturing process of the utility model:

1) making of pressing plate:, select for use carbon constructional quality steel to produce the lower platen and the top board of corresponding coaxial and same holes distance of Fig. 2 and Fig. 3 size respectively according to the cell size; Said lower platen is used to place the battery pile, and with the fixing pile of top board, last pile is suppressed through press with the nut screwing clamping external screw thread.

2) making of screw rod: according to the size in hole on the lower platen; Select for use stainless steel bar to make four screw rods shown in 4-6; The hole that guarantees screw rod bottom part body and lower platen is an interference fits, and screw rod main body top processes portion with external threads, and externally threaded size can be passed the hole on the top board; Along the radial position of screw rod main body, process length direction and be parallel to the screw rod center line, and be positioned at a rectangular through-hole at screw rod center; Male end in the screw rod main body processes a semi-open slot that communicates with rectangular opening, is beneficial to pile and separates in assembly fixture with lead-in wire.

3) assembling: rectangular through-hole is aimed at the position of lead-in wire, and four screw rods are vertically fixed on the lower platen, and the diameter that fixing back four screw rods constitute just in time matches with the diameter of cell, and after cell was put into and forms pile on the lower platen, it is vertical that pile keeps; After lead-in wire was inserted rectangular opening, drew through semi-open slot the end of lead-in wire, covers top board, with the external screw thread on the hex nut fastening screw, suppresses then, is prepared into the pile assembly fixture.

Claims

1. a thermal cell pile assembly fixture comprises from bottom to top lower platen, pile, top board, and is vertically connected at four screw rods between the upper and lower pressing plate, it is characterized in that: radially be equipped with a rectangular opening on the screw rod main body of said screw rod; Screw rod one end is an external screw thread, and the male end that is positioned at screw rod is equipped with a semi-open slot that communicates with rectangular opening.
