Description

Lock leaf profile tolerance gauge

Technical Field

The utility model relates to an utensil technical field is examined to the car lock leaf, especially relates to utensil is examined to lock leaf profile tolerance.

Background

Because the existing automobile industry is in great competition and the requirements on comfort and noise are more severe, the lock leaf is a part of the automobile part with higher size, the profile degree of the part after heat treatment must meet 0.2mm, the size deformation amplitude of the part is extremely large in the heat treatment process due to the profile characteristics of the part, in order to prevent bad outflow, the detection must be performed according to the sampling management requirements of a client, the existing detection of the profile degree area is performed point by point one by one, and the process of detecting 1 part needs at least 3 minutes.

If the size exceeds the profile tolerance by 0.2mm in the process of spot inspection, the whole product must be inspected, and the workload is particularly large.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the purpose of structure is in order to provide an utensil of examining of ability accuracy and quick inspection, and the main technical problem who solves is that the lock leaf clamping location must be accurate, and the reference position in the testing process is the same with the location order.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

utensil is examined to lock leaf profile tolerance is including base, locating plate, malleation active grab, side push active grab, fixes the locating plate on the base through locating pin and screw, has seted up a plurality of tooth grooves on the locating plate, the tooth groove is meshed with the lock leaf each other, is equipped with malleation active grab directly over the lock leaf malleation active grab one side is fixed with side push active grab, presss from both sides tightly to the lock leaf side direction.

According to the further technical scheme, two elastic sheet clips are fixed on the base, and a go-no go gauge I and a go-no go gauge II are fixed on the two elastic sheets respectively.

According to a further technical scheme, handles are oppositely arranged on two sides of the base.

According to a further technical scheme, a foot pad is arranged below the base.

Compared with the prior art, the beneficial effects of the utility model are that:

the checking fixture is accurately positioned in the axial direction, the side edge and the upper plane of the lock blade can be clamped tightly, the positioning accuracy is high, and the requirements of the shape and the position tolerance of the appearance can be met. The quick clamping structure is adopted, the clamping reliability is guaranteed, and the clamping speed is improved.

Drawings

Fig. 1 is a top view of a lock blade profile tolerance gauge provided by the present invention;

fig. 2 is a front view of the lock blade profile tolerance gauge provided by the utility model;

fig. 3 is the utility model provides a left side view is examined to lock leaf profile tolerance.

In the figure: the rapid clamp comprises a base 1, a pin bush 2, a positioning plate 3, a supporting pin 4, a positioning pin 5, an axial taper pin 6, a supporting seat 7, a side-push rapid clamp 8, a positive-pressure rapid clamp 9, a first go-no-go gauge 10, a second go-no-go gauge 11, a spring clip 12, a handle 13, a pad 14 and a screw 16.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, utensil is examined to lock leaf profile tolerance is including base 1, locating plate 3, malleation active grab 9, side push active grab 8, fixes locating plate 3 on base 1 through locating pin 5, screw 16, has seted up a plurality of tooth grooves on locating plate 3, tooth groove and lock leaf intermeshing each other are equipped with malleation active grab 9 directly over the lock leaf 9 one side of malleation active grab is fixed with side push active grab 8, presss from both sides tightly to the lock leaf side direction.

In this embodiment, two elastic sheet clips 12 are fixed on the base 1, and a go-no-go gauge one 10 and a go-no-go gauge two 11 are respectively fixed on the two elastic sheet clips 12.

In this embodiment, the two sides of the base 1 are oppositely provided with handles 13.

In this embodiment, a foot pad 14 is arranged below the base 1.

In the concrete practicality, fix the pin bushing 2 on base 1, insert axial tapering round pin 6 and slide in the Z direction certain limit, insert supporting pin 4 and guarantee that supporting pin 4 is at same Z axle height, screw 16 is locked after locating plate 3 is fixed and is inserted locating pin 5 on base 1, fix side push rapid clamp 8 on base 1 and ensure to move about and can effectively press from both sides tight lock leaf at 0-90 degrees within range, fix malleation rapid clamp 9 on base 1 and ensure to get at Z direction certain limit within range activity guarantee lock leaf and put normally, supporting seat 7, spring plate clamp 12, handle 13, 14 fix with the screw on base 1 of pad foot.

The lock leaf is positioned by the axial taper pin 6, the lock leaf is ensured to be positioned and only can move axially, the lock leaf is pushed to push the side-push quick clamp handle after being laterally abutted, the lock leaf is clamped to ensure that the lock leaf cannot shake, the positive-pressure quick clamp handle is pushed to clamp the lock leaf again, the lock leaf surface is ensured to be flatly attached to the checking fixture, the lock leaf is prevented from being tilted or shaken to influence detection, a gap between the lock leaf and the positioning plate is detected by a first pass-stop gauge and a second pass-stop gauge, smooth passing is realized, the positive-pressure quick clamp handle and the side-push quick clamp handle are pulled after the detection is finished, and the axial taper pin is taken out to take out the lock leaf, so that the detection work.
