Position detection greatly expands the detection functions of inspection tools and touch gauges, and can be adapted to high-efficiency detection of shape and size tolerances and dimensional tolerances for large quantities of products10.

Referring to FIG. 2 and FIG. 3 , the first touch gauge 2 includes a first touch gauge sleeve 21 and a first detection pin 22 . The first touch gauge sleeve 21 is tubular and has a first end and a second end, the first end of which corresponds to the groove body 111 . The first touch gauge sleeve 21 is protruded on the first vertical plate 20, and is installed on the platform 1 through the first vertical plate 20; the first vertical plate 20 is vertically arranged, facing the groove body 111, fixed and vertically connected to the platform 1 Above; the first end of the first touch gauge cover 21 is fixed and vertically connected to the first vertical plate 20 .

Specifically, the second end of the first touch gauge cover 21 has a first upper limit reference side 211 and a first lower limit reference side 212, and the first upper limit reference side 211 is farther away from the first touch gauge cover 21 than the first lower limit reference side 212. first end.

The first detection pin 22 is movably installed in the first touch gauge sleeve 21 , and can protrude from the first end of the first touch gauge sleeve 21 and pass through the first vertical plate 20 to detect the groove body 111 . The inner peripheral surface of the first touch gauge cover 21 is attached to the outer peripheral surface of the first detection pin 22; both ends of the first detection pin 22 are planes, and are all vertically arranged; the extension direction of the first detection pin 22 is perpendicular to The end surface of the first vertical plate 20 and the first detection pin 22 corresponds to the groove body 111 .

Specifically, relative to the extension direction of the first detection pin 22 , the shape and size of the cross section of the first detection pin 22 are configured to be the same as the shape and size of the cross section of the groove body 111 . Wherein, the cross section of the first detection pin 22 , the cross section of the groove body 111 , the bottom surface and the opening of the groove body 111 are all rectangular in shape and size.

In this embodiment, the first touch gauge 2 has a simple structure and is easy to use. It is installed on the platform 1 through the first vertical plate 20, which is relatively stable and can achieve more accurate detection results.

In this embodiment, the method for detecting the depth and position of the groove body 111 on the first plane 11 by the first touch gauge 2 is as follows:

First, if the position of the groove body 111 of the tested product 10 is qualified, then the groove body 111 is facing the end face of the first detection pin 22, that is, the extending direction of the groove body 111 from the bottom surface to the opening is the same as that of the first detection pin 22. The extension and movement directions coincide exactly.

Drive the first detection pin 22 to move towards the groove body 111. According to the shape and size of the cross section of the first detection pin 22 and the shape and size of the cross section of the groove body 111 are the same, if the first detection pin 22 can extend into the groove body 111 If the opening of the groove body 111 can be abutted against the bottom surface of the groove body 111, the position of the groove body 111 meets the tolerance requirement; Then the position of the groove body 111 does not meet the tolerance requirement.

Second, assume that if the depth of the groove body 111 of the tested product 10 is qualified, then when the first detection pin 22 abuts against the bottom surface of the groove body 111, the first detection pin 22 deviates from the end surface of the product 10 and is located at the first upper limit. between the reference side 211 and the first lower limit reference side 212 .

On the premise that the position of the groove body 111 meets the tolerance requirements, drive the first detection pin 22 to abut against the bottom surface of the groove body 111; The positional relationship of the lower reference side 212 is used to determine the depth of the groove body 111 .

If the first detection pin 22 deviates from the end surface of the product 10 and fully extends into the first upper limit reference side 211 and the first lower limit reference side 212 , the depth of the groove body 111 is too deep and does not meet the tolerance requirements.

If the first detection pin 22 deviates from the end surface of the product 10 and completely protrudes out of the first upper limit reference side 211 and the first lower limit reference side 212 , the depth of the groove body 111 is too shallow to meet the tolerance requirements.

If the first detection pin 22 faces away from the end surface of the product 10 and is located between the first upper limit reference side 211 and the first lower limit reference side 212 , then the depth of the groove body 111 meets the tolerance requirement.

Referring to FIG. 4 and FIG. 5 , the second touch gauge 3 includes a second touch gauge sleeve 31 and a second detection pin 32 . The second touch gauge sleeve 31 is tubular and has a first end and a second end, the first end of which is facing the second plane 12 .

If, among the three second detection pins 32, one of the second detection pins 32 deviates from the end face of the product 10 and is not located between the second upper limit reference side 311 and the second lower limit reference side 312, then this second detection pin 32 The position of the point on the second plane 12 corresponding to the pin 32 does not meet the tolerance requirement, so it can be concluded that the flatness of the second plane 12 does not meet the tolerance requirement.

If, among the three second detection pins 32, two of the second detection pins 32 are away from the end face of the product 10 and are not located between the second upper limit reference side 311 and the second lower limit reference side 312, then the two second detection pins 32 The position of the point on the second plane 12 corresponding to the pin 32 does not meet the tolerance requirement, so it can be concluded that the flatness of the second plane 12 does not meet the tolerance requirement.

If the end faces of the three second detection pins 32 away from the product 10 are all located between the second upper limit reference side 311 and the second lower limit reference side 312, then the three measured points corresponding to the three second detection pins 32 are not located.

In this embodiment, the measuring rod 4 is simple in structure and easy to use, and is installed on the platform 1 through the third vertical plate 40, which is relatively stable and can achieve more accurate detection results.

In this embodiment, the method for detecting the position of the hole 131 on the third plane 13 by the measuring rod 4 is as follows:

Suppose, if the position of the hole 131 of the tested product 10 is qualified, then the hole 131 is facing the end of the measuring rod 4, that is, the axis of the hole 131 coincides with the axis and the moving direction of the measuring rod 4 completely.

Drive the measuring rod 4 to move towards the hole 131. If one end of the measuring rod 4 can pass through the hole 131, the position of the hole 131 meets the tolerance requirement; if one end of the measuring rod 4 cannot pass through the hole 131, then the position of the hole 131 does not meet the tolerance Require.

Correspondingly, three second measuring rods 5 are movably pierced or screwed on the second vertical plate 30; the diameter of the second measuring rods 5 is configured to be the same as the diameter of the second hole. Wherein, the three second measuring rods 5 all point to the corresponding second holes.

In this embodiment, the method for detecting the position of the second hole on the second plane 12 by the second measuring rod 5 is as follows:

Suppose, if the position of the second hole of the tested product 10 is qualified, then the second hole is facing the end of the second measuring rod 5, that is, the axis of the second hole coincides with the axis and the moving direction of the second measuring rod 5 completely.

Drive the second measuring rod 5 to move towards the second hole, if one end of the second measuring rod 5 can pass through the second hole, then the position of the second hole meets the tolerance requirements; if one end of the second measuring rod 5 cannot pass through the second hole hole, the position of the second hole does not meet the tolerance requirements.
