Abstract
The utility model relates to a device for helping a jump ring pressed in a rear cover, in particular to a device for helping a locating snap ring pressed in an automotive booster pump valve spool. The device comprises two parts: a wood club (1) and a hollow sleeve (2), wherein the outer wall of the wood club (1) has a taper of (1:2)-(1:3); the bottom part of the hollow sleeve (2) has a chamfer; the wood club (1) is a cylinder with a smaller radius from the head part to the middle part; the bottom part of the wood club (1) is provided with an indent; the head part of the indent is a tapered indent; and the lower part of the indent is a cylindrical indent. The device is simple to operate, is low in cost and is very practical.
Description
Technical field
The utility model relates to a kind of tooling device, specifically automobile boost pump valve pool location snap ring help into device.
Background technology
Though automobile bonnet jump ring is not one of core part, but it also plays a part maintenance for the pump housing, prevent the part displacement, also be all to be one of indispensable accessory in every money pump housing, existing method of operating is assembled into Circlip tongs, because this kind of jump ring hardness is very high, personnel are when using the Circlip tongs cramping to enter, need consume very great strength and just can compress into, operating efficiency obviously reduces.Developing this frock at this situation press-fits.
Summary of the invention
The utility model provides the bonnet jump ring to help into device, and it can compress into pump housing bonnet groove to each jump ring power-assisted of making the finished product boost pump again, and cost is low, and is easy to use, the efficient height.
The utility model technical solution is to comprise that rod hammer (1) and the bottom of the tapering of outer wall belt 1:2 ~ 1:3 have logical heart sleeve pipe (2) two parts of chamfering, the head of described rod hammer (1) is that radius is less than the cylinder of head and tail radius 8mm to the middle part, the bottom band of rod hammer (1) caves in, this head that caves in is conical indentation, and the bottom of caving in is the cylinder depression.
Operation principle of the present utility model is: this frock has the rod hammer (1) of tapering to have logical heart sleeve pipe (2) two parts of chamfering to form with one by one, earlier jump ring is put in the logical heart sleeve pipe (2) of chamfering, the logical heart sleeve pipe (2) that to put jump ring again is placed on the bonnet place, lead to the through hole of heart sleeve pipe (2) along subduing with tapering rod hammer (1) from chamfering again, along with the power-assisted of tapering rod hammer (1), jump ring is easily compressed into groove.
So advantage of the present utility model can compressed into pump housing bonnet groove to each jump ring power-assisted of making the finished product boost pump again, cost is low, and is easy to use, the efficient height.
Description of drawings
Fig. 1 is organigram of the present utility model.
The specific embodiment
Embodiment 1
According to shown in Figure 1, this device comprises that rod hammer (1) and the bottom of the tapering of outer wall belt 1:2 have logical heart sleeve pipe (2) two parts of chamfering, the head of described rod hammer (1) is that radius is less than the cylinder of head and tail radius 8mm to the middle part, the bottom band of rod hammer (1) caves in, this head that caves in is conical indentation, and the bottom of caving in is the cylinder depression.
Basic identical with the structure of embodiment 1, its difference is that the outer wall of rod hammer (1) is the tapering of 1:3.
Claims (1)
1. the bonnet jump ring helps into device, it is characterized in that comprising that rod hammer (1) and the bottom of the tapering of outer wall belt 1:2 ~ 1:3 have logical heart sleeve pipe (2) two parts of chamfering, the head of described rod hammer (1) is that radius is less than the cylinder of head and tail radius 8mm to the middle part, the bottom band of rod hammer (1) caves in, this head that caves in is conical indentation, and the bottom of caving in is the cylinder depression.
