Abstract

The utility model discloses a special fixing base of punching press iron axle, including the base with protect axle piece, wherein be equipped with on the base size with protect the concave position that the axle piece is the same, the chamber is placed to concave being equipped with in concave position bottom surface, should protect is equipped with supplied an iron through -hole of putting into that runs through top and bottom on the axle piece, when protecting axle piece and put into concave position, the axle core of this through -hole aligns with a core in the shaft hole of placing the accessory that is used for spool being connected with iron in placing the chamber mutually, when the event is put into iron axle from the through -hole that protects the axle piece, the axle core of iron axle aligns with a core in accessory shaft hole mutually, consequently, it goes by holding the iron axle to need not the rethread hand, can guarantee through the through -hole restriction that the iron axle keeps vertical position, iron axle compressive deformation can also be avoided to the through -hole simultaneously, so post -installation part disability rate is low, and operating efficiency has been improved, which substantially saves cost.

Description

A kind of Special fixing reservation of punching press iron axle

Technical field

The utility model relates to a kind of assembly of manual decompressor, specifically a kind of Special fixing reservation of punching press iron axle.

Background technology

In toy production process, particularly there is mobilizable toy, all be unable to do without to be connected with accessory by iron axle and coordinate and realize movable, and the connection of iron axle and accessory is at present all manually mostly, as shown in Figure 1, utilize hand punch, accessory is placed on board, then hand-held the assembling axis hole of iron axle near accessory, iron axle is pressed in the axis hole of accessory by another hand operated hand punch, in whole process, iron axle is that the hand by holding it controls its perpendicularity, therefore be easy to cause the assembling accurate part rejection made, and iron axle is easy to the distortion that is stamped, therefore cost is added, simultaneously such manual operation efficiency comparison is low.

Summary of the invention

The purpose of this utility model is to solve above-mentioned existing problems, provides a kind of contributing on hand punch to raise the efficiency and reduces the Special fixing reservation of punching press iron axle of scrappage.

The technical solution of the utility model is achieved in that

A kind of Special fixing reservation of punching press iron axle, be characterized in comprising base and protecting axle block, described base is provided with size and protects the identical recess of axle block with described, described recess bottom surface is arranged with placed cavity, the described axle block that protects is provided with the through hole that Gong the iron axle that runs through top and bottom puts into, and the axle core of described through hole aligns for the axle core of the axis hole of accessory be connected with iron axle with being placed in placed cavity.

Conveniently take out and protect axle block, the recess edge of described base is provided with the breach that two symmetrical convenience will be protected axle block and take out from base.

In order to ensure can be more steady after protecting axle block puts into recess, the degree of depth of described placed cavity is not less than the height of the accessory be placed therein.

Further, described in protect axle block and include square block and cylinder, described cylinder is positioned at centre position, square block upper surface, and described through hole leads to below square block from the upper end middle straight of cylinder.

Recess shape size on described base is identical with the described square block protecting axle block.

Design different bases according to the accessory shape that will assemble, as: as described in placed cavity on base be to hold the circular cavity that accessory is gear.

The utility model is owing to adopting the Special fixing reservation including base and protect axle block, accessory is placed in base, then cover and protect axle block, again iron axle is put into from the through hole protecting axle block, now the axle core of iron axle and the axle core of accessory axis hole align, finally with hand operated hand punch, iron axial compression is entered in accessory, therefore without the need to going to hold iron axle by hand again, can ensure that iron axle keeps plumbness by through hole restriction, through hole can also avoid iron axle compressive deformation simultaneously, so the part rejection rate after assembling is low, and improve operating efficiency, greatly provide cost savings.

Below in conjunction with accompanying drawing, the utility model is further described.

Detailed description of the invention

As shown in Figures 2 to 4, a kind of Special fixing reservation of punching press iron axle, comprise base 1 and protect axle block 2, wherein base 1 is provided with size and protects the identical recess of axle block 2 11 with described, placed cavity 12 is arranged with in recess 11 bottom surface, this protects axle block 2 and is provided with the through hole 20 that Gong the iron axle 3 that runs through top and bottom puts into, when protecting axle block 2 and putting in recess 11, the axle core of this through hole 20 aligns for the axle core of the axis hole 41 of accessory 4 be connected with iron axle 3 with being placed in placed cavity 12, therefore when iron axle 3 is put into from the through hole 20 protecting axle block 2, the axle core of iron axle 3 and the axle core of accessory 4 axis hole 41 align, therefore without the need to going to hold iron axle 3 by hand again, can ensure that iron axle 3 keeps plumbness by through hole 20 restriction, through hole 20 can also avoid iron axle 3 compressive deformation simultaneously, so the part rejection rate after assembling is low, and improve operating efficiency, greatly provide cost savings.

As shown in Figure 3, the base 1 of this embodiment is provided with two symmetrical breach 13 at its recess 11 edge, when after the good iron axle 3 of punching press, stretch into respectively in breach 13 can mention protecting axle block 2 like a cork with thumb and forefinger.In addition in order to ensure can be more steady after protecting axle block 2 puts into recess 11, the degree of depth of this placed cavity 12 is not less than the height of the accessory 4 be placed therein.The base 1 of this embodiment is square frame pedestal, protect axle block 2 and be similarly square block 21, therefore the recess 11 on the base 1 of correspondence is also square recess, and match with the square block 21 protecting axle block 2, in the middle of the upper surface of square block 21, be upwards extended with cylinder 22, namely through hole 20 leads to below in the middle of the upper end of cylinder 22 always.The placed cavity 12 of this embodiment is circular-shaped, concave cavity, and the accessory 4 for placing is gear, changes base 1 according to the accessory 4 that required and iron axle 3 assemble.

The operation principle of the Special fixing reservation of this punching press iron axle is as follows:

As shown in Figure 5, device under this state is in state to be punched, first accessory 4 is placed in the placed cavity 12 of base 1, then put in the recess 11 of base 1 by protecting axle block 2, cover accessory 4, then an iron axle 3 is put into from the through hole 20 protecting axle block 2, finally whole Special fixing reservation is placed on the board 61 of hand punch 6, aim at the staking punch 62 of hand punch 6; Next step hand steered firmly Special fixing reservation, the Rocker handle 63 of another hand rotation manual stamping machine 6, makes staking punch 62 punching press iron axle 3 downwards, make iron axle 3 move down and be inserted in the axis hole 41 of accessory 4, as shown in Figure 6, finally complete assembling, form iron axle 3 and the close-fitting part of accessory 4.

Although the utility model describes with reference to specific embodiment, this description not meaning that is construed as limiting the utility model.With reference to description of the present utility model, other changes of the disclosed embodiments, all can expect for those skilled in the art, this change should belong in appended claims limited range.
