Abstract

Riveting type sensor, including copper piece, counterbore is offered in the copper piece, and magnet is placed in the counterbore, also sets up triangle reverse chamfered groove in the counterbore, it applies glue in the inner surface of counterbore, and triangle reverse chamfered groove is poured into, after being put into magnet in counterbore, with the upper end of staking punch punching press copper piece, it is stamped and formed out the parcel for wrapping up magnet, also forms pressing notch in the parcel.The utility model has the following beneficial effects: completing the package action to copper piece inner magnet by stamping device, so in use, the magnet in sensor will not be dropped out, and ensure that the service life of sensor.

Description

Riveting type sensor

Technical field

The utility model belongs to automobile sensor field, and in particular to riveting type sensor.

Background technique

The production method of automobile sensor on the market is very single at present, it is generally the case that one is opened in copper piece Deep gouge applies glue in deep gouge in advance, and then magnet is put into, by glue magnet and copper piece it is glutinous together with.

This adhesive method, magnet are easy to drop out out of copper piece, will lead to sensor failure, the magnet to drop out is all Disappear, be difficult to repair, needs replacing a new sensor.

Summary of the invention

Aiming at the shortcomings in the prior art, the utility model provides riveting type sensor, to solve existing sensor The problem of magnet is binded with glue merely, is simply fallen out.

The utility model is achieved through the following technical solutions.

Riveting type sensor, including copper piece offer counterbore in the copper piece, place magnet in the counterbore, It is characterized in that, triangle reverse chamfered groove is also set up in the counterbore, apply glue in the inner surface of counterbore, and pour into triangle chamfering Slot after being put into magnet in counterbore, with the upper end of staking punch punching press copper piece, is stamped and formed out the parcel for wrapping up magnet, institute Pressing notch is also formed in the parcel stated.The sensor is wrapped up by parcel, and such magnet all can at all positions It is limited, no matter how sensor moves, and internal magnet all will not fall off.

Preferably, the height of the pressing notch gradually rises from the outside to the inside.Press the difference in height model of notch It is trapped among between 1mm ~ 5mm, difference in height is bigger, and the parcel to extend internally is longer.

Preferably, the pressing notch annular spread, and be four.Minimum of three is also possible to six, annular packet Wrap magnet.

Preferably, the section of the parcel is fan-shaped.Increase package area.

Compared with prior art: the package action to copper piece inner magnet being completed by stamping device, in this way in use process In, the magnet in sensor will not drop out, and ensure that the service life of sensor.

Specific embodiment

Riveting type sensor, including copper piece 1 offer counterbore in the copper piece 1, place magnet 2 in the counterbore, Triangle reverse chamfered groove 4 is also set up in the counterbore, is applied glue in the inner surface of counterbore, and pour into triangle reverse chamfered groove 4, in counterbore After being inside put into magnet 2, with the upper end of staking punch punching press copper piece 1, it is stamped and formed out the parcel for wrapping up magnet 2, the packet It wraps up in and also forms pressing notch 5 in portion, the height of the pressing notch 5 gradually rises from the outside to the inside, the pressing Notch annular spread, and be four, the section of the parcel is fan-shaped.

In use, parts to be processed 14 is put into first recessed to being formed above lower locating piece 13 and lower cushion block 12 In slot, places and complete.

After the completion of placement, due to the presence of verification set 15, upper punch 19 will carry out upper downslide in verification set 15 Dynamic, the mandril 17 in upper punch 19 is independent in through-hole, and block is arranged on mandril 17, and spring is placed in the top of block 18, upper punch 19 and mandril 17 are declined together by hydraulic system, and due to the presence of spring 18, mandril 17 drops to magnet 2 Top, and copper piece 1 is not touched, magnet 2 is resisted, upper punch 19 continues downwards at this time, and opposite position occurs for upper punch 19 and mandril 17 The variation set causes internal spring 18 to become pressured state from relaxation state, and upper punch 19 is to be fixedly connected with upper plate 20 Upper punch 19 and then push together, press to the upper end of copper piece 1, and the bottom of upper plate 20 be placed exactly in column 16 just on Side, multiple wedge blocks 191 exert a force to the upper end of copper piece 1 at this time.

Since the section of wedge block 191 is in triangular shape, inclination upwards from the outside to the inside, therefore in course of exerting pressure, meeting exists Molding pressing notch 5 in copper piece 1, and 1 ecto-entad of copper piece is pushed, copper piece 1 forms parcel, which has wrapped up magnetic Body 2 prevents magnet 2 from escaping copper piece, and in automobile in use process, magnet 2 is limited the finished parts, can not be detached from copper piece 1, make With year limit for length, it is not easy to damage.

Complete punching press after, mandril 7, upper punch 19 follow upper plate 20 move up, in order to prevent 2 adhesion of magnet together Upwards, after spring 18 is pressurized, a power relatively downward is had, therefore mandril 17 follows upper plate 20 to moving up in upper punch 19 When dynamic, late it can move up.

During spring 18 slowly becomes relaxation state from pressured state, mandril 17 can also be against the top of magnet 2, directly Loosen completely to spring 18, mandril 17 upwards, is put into a new parts to be processed 14, repeats the above steps.

The protection scope of the utility model includes but is not limited to embodiment of above, and the protection scope of the utility model is to weigh Subject to sharp claim, replacement, deformation, the improvement that those skilled in the art that any pair of this technology is made is readily apparent that are each fallen within The protection scope of the utility model.
