Background

The full run-out comprises radial full run-out and end face full run-out, wherein the radial full run-out is the difference value between the maximum displacement and the minimum displacement of an indicator which is in light contact with the outer peripheral surface of a cylindrical object in the radial direction of the object when the cylindrical object rotates around the axis of the cylindrical object for one circle. The end face full run-out refers to the difference value between the maximum displacement and the minimum displacement of the indicator which is in light contact with the end face of the cylindrical object in the axial direction of the object when the cylindrical object rotates around the axis of the cylindrical object for one circle.

Referring to fig. 6, the cylinder assembly includes a member to be fixed 810 and a member to be fixed 820, the member to be fixed 810 is in a hollow circular ring shape, and a part of the member to be fixed 820 is inserted into the member to be fixed 810 and can rotate relatively. In the view shown in fig. 6, that is, the lower end of the member to be fixed 820 is inserted into the annular member to be fixed 810 from the top down to realize the rotational connection, the portion of the member to be fixed 820 which is not inserted into the member to be fixed 810 is located at the upper end of the member to be fixed 810. In the related art, when the full-run-out detection device performs full-run-out detection on a single cylindrical object, the two ends of the detected object are limited through the limiting parts so as to avoid position deviation along the axial direction of the detected object. When the relative full runout is measured, the to-be-fixed member 810 needs to be limited, the position of the to-be-fixed member 810 is kept fixed, the to-be-detected member 820 rotates relative to the to-be-fixed member 810, and the full runout value of the to-be-detected member 820 relative to the to-be-fixed member 810 is measured in the rotating process. Obviously, for the structure shown in fig. 6, since the member to be detected 820 is rotatably connected to the upper end of the member to be fixed 810, the upper end of the member to be fixed 810 is shielded, and if a conventional detection device is used, the two ends of the member to be fixed 810 cannot be limited, so that the detection cannot be performed.

Referring to fig. 1 to 5, an embodiment of the present invention provides a full runout detection apparatus for detecting a full runout value of a to-be-detected element 820 relative to a to-be-fixed element 810, as shown in fig. 6. The utility model relates to a full detection device that beats that embodiment provided includes frame, centre gripping subassembly, detection piece 400 and driving piece 510, and centre gripping subassembly, detection piece 400 and driving piece 510 are all installed in the frame. The clamping assembly includes a first clamping member 200 and a second clamping member 300, which are spaced apart from each other. The full-jump detection device has a detection state, in the detection state, the first clamping piece 200 can abut against a first area on the outer circumferential surface of the piece to be fixed 810, the second clamping piece 300 can abut against a second area on the outer circumferential surface of the piece to be fixed 810, and the first area is located on the opposite side of the second area. The detecting member 400 includes a detecting head 410, the detecting head 410 is used for contacting with the member 820 to be detected, and during the detecting process, the detecting head 410 always keeps touching the member 820 to be detected. The power output end of the driving member 510 is used for connecting with the member to be detected 820, so as to drive the member to be detected 820 to rotate at least one circle relative to the member to be detected 810. During the rotation of the member to be fixed 820 relative to the member to be fixed 810, the detecting member 400 can record the displacement of the detecting head 410.

In the full-run-out detection apparatus in this embodiment, when detecting the full-run-out value of the to-be-detected piece 820 relative to the to-be-fixed piece 810, the to-be-fixed piece 810 is fixed by respectively clamping the first clamping piece 200 and the second clamping piece 300 in two opposite regions on the outer peripheral surface of the to-be-fixed piece 810. When the fixing member 810 is clamped and fixed, the fixing member 810 is fixed in position by being clamped on the outer circumferential surface of the fixing member 810, so that the to-be-detected member 820 which is rotatably connected to the end of the fixing member 810 is not easy to interfere with the clamping assembly in position to influence the installation of the clamping assembly, the clamping assembly is not hindered from clamping the fixing member 810, and the fixing member 810 can be smoothly fixed in position. The detecting head in the detecting member 400 can contact with the member 820 to be detected, and during the driving member 510 drives the member 820 to be detected to rotate relative to the member 810 to be fixed, the detecting member 400 can record the displacement of the detecting head, and the difference value between the maximum value and the minimum value in the displacement is the corresponding full run-out value.

Specifically, the frame includes a substrate 110, and a first mounting base 120, a second mounting base 130 and a third mounting base 140 are mounted on the substrate 110. The first clamping member 200 is mounted on the first mounting seat 120, the second clamping member 300 is mounted on the second mounting seat 130, and the driving member 510 is mounted on the third mounting seat 140. A mounting frame 150 is further mounted on the base plate 110, and the detecting member 400 is mounted on the mounting frame 150.

Referring to fig. 1 to 5, in some embodiments, the detecting element 400 is slidably connected to the frame, and the detecting element 400 can move along the axial direction of the detecting element 820 until the detecting head 410 contacts with the outer peripheral surface or the end surface of the detecting element 820. Specifically, the detecting member 400 is a displacement sensor. The mounting frame 150 can be a telescopic rod capable of extending along the axial direction of the piece 820 to be detected, and the mounting frame 150 extends and retracts to enable the detection piece 400 fixedly connected to the mounting frame 150 to move along the axial direction of the piece 820 to be detected, so that the detection head 410 is moved to be in contact with the outer peripheral surface or the end surface of the piece 820 to be detected. If the detecting head 410 contacts with the outer peripheral surface of the member 820 to be detected, when the member 820 to be detected rotates relative to the member 810 to be detected, the relative radial total run-out value can be obtained by recording the displacement difference of the detecting head 410 along the radial direction of the member 820 to be detected. If the detecting head 410 is in contact with the end face of the piece 820 to be detected, when the piece 820 to be detected rotates, the relative end face full run-out value can be obtained by recording the displacement difference of the detecting head 410 along the axial direction of the piece 820 to be detected. In this embodiment, the detecting element 400 moves along the axial direction of the element 820 to be detected, so that the radial full runout value and the end face full runout value can be switched, and the two types of full runout values can be comprehensively detected. Of course, in other embodiments, a driving member such as an air cylinder or a linear motor may be provided, and the driving member drives the detecting member 400 to move along the axial direction of the object 820 to be detected.

Specifically, the mounting frame 150 includes a first mounting portion 151 and a second mounting portion 152, which are integrally connected and bent relatively. The first mounting portion 151 is located at one side of the object 820 to be detected, and the second mounting portion 152 is located at one end of the object 820 to be detected. A first detection head facing the outer peripheral surface of the object 820 to be detected may be fixedly mounted on the first mounting portion 151, and a second detection head facing the end surface of the object 820 to be detected may be fixedly mounted on the second mounting portion 152. The first detection head is in light touch with the peripheral surface of the piece to be detected 820, so that the detection of the relative radial full run-out is realized; and the second detection head is in light touch with the end face of the piece to be detected 820, so that the detection of the full run-out of the opposite end face is realized. The first detection head and the second detection head can be arranged alternatively or simultaneously.

It should be noted that the touching of the detection head on the corresponding position of the to-be-detected piece 820 means that the detection head always contacts with the corresponding position of the to-be-detected piece 820, but the detection head does not affect the rotation of the to-be-detected piece 820 relative to the to-be-fixed piece 810.

Referring to fig. 1 to 5, in some embodiments, a sliding mechanism 160 is slidably connected to the base plate 110, and the mounting frame 150 is fixedly connected to the sliding mechanism 160.

The to-be-fixed part 810 is encircled by the two V-shaped clamping arms, the first area on the to-be-fixed part is limited, and meanwhile, the second clamping part 300 is matched to abut against the second area on the opposite side of the first area, so that the to-be-fixed part 810 is clamped and fixed and is limited at a preset position. In this embodiment, two clamping arms that are "V" shape encircle treat mounting 810, can increase area of contact to spacing from two positions makes spacing more stable, treats that mounting 810 has the probability of offset lower.

The telescopic end of the cylinder is used for stretching so as to approach or keep away from the part to be fixed 810 between the first clamping piece 200 and the second clamping piece 300. When the position is limited, the telescopic end of the cylinder extends out towards the to-be-fixed part 810 until the other end of the to-be-fixed part 810 abuts against the first clamping part 200, so that the clamping and the position limitation are realized. The telescopic end of the cylinder is used for telescopic adjustment, so that the detection device is suitable for the to-be-fixed pieces 810 with different sizes, and the application range of the detection device is wider. Certainly, in other embodiments, a rubber pad and other components may be installed at the telescopic end of the cylinder, and at this time, the portion of the second clamping member 300 for supporting the second region is the rubber pad, and the to-be-fixed member 810 can be protected by the rubber pad, so as to prevent the to-be-fixed member 810 from being damaged due to an excessive clamping force.

Alternatively, a strip-shaped through groove may be provided on the substrate 110, and the second clamping member 300 may be fixedly mounted at any position of the through groove by a threaded fastener, which is equivalent to connecting the through holes into a whole. In this embodiment, the second mounting seat 130 is detachably connected to the substrate 110, and in a detached state, the second mounting seat 130 can slide relative to the substrate 110 to enable the second clamping member 300 to approach or depart from the first clamping member 200, so as to be suitable for the members to be fixed 810 with different sizes. In some embodiments, by changing the position of the second mounting seat 130 mounted on the substrate 110 and matching with the movement of the portion of the second clamping member 300 itself for abutting against the second region, the detection device can be applied to more sizes of members to be fixed 810, and the application range of the detection device is increased.
