Description

A practical detection tool for checking workpiece clearance

technical field

The utility model relates to the technical field of mechanical manufacturing, in particular to a practical detection tool for checking workpiece clearance.

Background technique

In the production of the cylinder head, when the bottom surface is processed, there is currently a lack of effective inspection tools to detect the gap between the cylinder head and the tooling positioning surface. Therefore, it is very necessary to have a simple and reliable inspection tool.

The disclosure of the above background technology content is only used to assist the understanding of the concept and technical solution of the present invention, and it does not necessarily belong to the prior art of this patent application. If there is no clear evidence that the above content has been disclosed on the filing date of this patent application The above background art should not be used to evaluate the novelty and inventive step of the present application.

Utility model content

Aiming at the above-mentioned technical problems, the utility model provides a detection tool with simple operation and accurate detection for checking the gap between workpieces.

To achieve the above object, the utility model adopts the following technical solutions:

A detection tool for practically checking the gap between workpieces, comprising a handle, an insert plate and an extruded telescopic plate; the handle is provided with a slot, and the middle and rear part of the insert plate is inserted into the slot to be fixed; the extrusion The telescopic plate is connected and fixed above the front part of the inserting plate by means of spring positioning pins; the spring positioning pins are distributed between the extruding telescopic plate and the inserting plate; the rear part of the extruding telescopic plate is also combined with There is a pointer rod; a vertical measuring ruler is also combined with the insert plate or the handle; the vertical measurement ruler is distributed on one side of the pointer rod.

Further, the extruded telescopic board is connected and fixed on the front part of the plug-in board through four or more sets of the above-mentioned spring positioning pins.

Further, a rolling wheel group is also distributed on the bottom surface of the plug board.

Further, bolt holes are also provided on the handle, and through holes are correspondingly provided on the insert plate; the insert plate is detachably fixed in the slot of the handle by means of bolt assemblies.

Further, the handle is made of plastic.

Compared with the prior art, the utility model has the beneficial effects: the utility model is provided with an insert plate and an extruded telescopic plate that can be stretched up and down relative to the insert plate. It can be stretched up and down, and it can be judged whether each gap reaches the standard through the beating of the pointer rod; the friction force of moving during detection is effectively reduced by the rolling wheel set on the bottom surface of the plug-in board to ensure smoother operation; the plug-in board and the handle pass through Open and disassemble the connection, it is conducive to flexible replacement, and the use effect is good.

Fig. 1 is the structural representation of the present utility model;

Figure 2 is a cross-sectional view of the utility model after assembly of the plug-in board and the extruded telescopic board.

Detailed ways

As shown in Figures 1 to 2, a practical detection tool for checking the gap between workpieces includes a handle 1, an insert plate 2 and an extruded telescopic plate 3; the handle 1 is provided with a slot, and the handle 1 is also Bolt holes 1-1 are provided, and through holes are correspondingly provided on the plug-in board 2; . The extruded telescopic plate 3 is connected and fixed above the front part of the plug-in board 2 through four sets of spring positioning pins; the spring positioning pins are distributed between the extruded telescopic board and the plug-in board; in this embodiment In the example, the base 5-1 of the spring positioning pin is fixed in the base fixing groove of the plug board 2, and the top of the telescopic pin head 5-2 of the spring positioning pin is fixed on the extrusion telescopic board 3 in the pin head fixing groove; the extruded telescopic plate 3 can be extruded up and down relative to the insert plate 2 when squeezed. The rear part of the extruded telescopic plate 3 is also combined with a pointer rod 4; in this embodiment, the handle 1 is also combined with a vertical measuring ruler 1-2; of course, the vertical measuring ruler 1- 2 can also be distributed on the plug board 2, just make sure that it is distributed on one side of the pointer rod 4. In order to achieve better detection operation, the bottom surface of the plug-in board 2 is also distributed with a rolling wheel group 2-1. In this embodiment, the handle 1 is made of plastic, and the inserting plate 2 and the extruded telescopic plate 3 are made of metal material.

When in use, by extruding the insert plate 2 and the extruding telescopic plate 3, and inserting the gap between the bottom surface of the cylinder head and the positioning surface of the tooling, and then pushing the device, if the gap between the bottom surface of the cylinder head and the positioning surface of the tooling meets the standard , the pointer rod 4 points to a certain reading, if there is a gap that is too large or too small, the pointer rod 4 points to the reading will change accordingly, so check whether the gap reaches the standard. Of course, the utility model is not only suitable for the detection of the gap between the cylinder head and the positioning surface of the tooling, but also can be applied to the detection of the clearance between the cylinder head and the positioning surface during processing of other components, and the operation is simple and the detection is accurate and intuitive.
