Detailed Description
The rare earth NdFeB magnetic steel surface magnetic measurement clamp comprises a base 1, a fastening hoop 4, a longitudinal positioning strip 8 and a transverse positioning strip 6 (see the accompanying drawings 1 and 2 in the specification).
The base 1 is provided with a probe groove 2; a fastening hoop 4 (see figure 1 of the specification) is arranged on the base 1 above the lower end of the probe groove 2 through a bolt 3. The probe groove 2 is in a convex structure. The shape of the probe groove 2 is consistent with the mechanism of the probe of the surface magnetic detector, and the probe of the detector can be placed in the probe groove 2 during operation, and the position of the probe in the probe groove 2 can be transversely adjusted according to the requirement. After the adjustment probe is placed inside the probe recess 2, the adjustment probe can be secured inside the probe recess 2 by tightening the bending straps 4.
The two sides of the upper end of the probe groove 2 are slidably provided with transverse positioning strips 6 through longitudinal guide grooves 5. The transverse positioning strip 6 can slide back and forth in the longitudinal direction under the guidance of the longitudinal guide groove 5, and other actions cannot be generated, so that the transverse positioning strip 6 can always keep a horizontal state, and the problem of positioning deviation of a workpiece after the transverse positioning strip 6 deviates from the position is avoided.
The base 1 at the lower end of the transverse locating strip 6 is provided with a longitudinal locating strip 8 (see figure 2 of the specification) through symmetrically arranged transverse guide grooves 7. Two groups of guide sliding blocks 13 are symmetrically and fixedly arranged at the lower end of the longitudinal positioning strip 8; the guide slide 13 is slidingly connected to the corresponding transverse guide groove 7 (see fig. 4 and 5 of the description). Under the action of the guide slide block 13, the longitudinal positioning strip 8 can move back and forth along the transverse guide groove 7 in the transverse direction when being stressed, and can be kept in a vertical state all the time, so that the purpose of positioning the transverse positioning strip 6 is achieved.
Two sections of the longitudinal positioning strip 8 are symmetrically provided with fastening lugs 14; the fastening lugs 14 are screwed with locking screws 15 (see fig. 5 and 6 of the description). When the locking screw rod 15 is screwed down in the working process, the longitudinal positioning strip 8 can be fixedly connected with the base 1 under the action of the locking screw rod 15, so that the problem that the longitudinal positioning strip 8 is easy to move can be avoided.
The longitudinal positioning strip 8 is of a hollow structure; one end of the transverse locating strip 6 extends to the inside of the longitudinal locating strip 8; a control screw rod 9 is arranged in the longitudinal positioning strip 8 through a bearing; one end of the control screw rod 9 extends to the outer side of the longitudinal positioning strip 8 and is connected with a control worm wheel 10; a control worm 11 is arranged on the base 1 at the lower end of the control worm wheel 10; the control worm 11 is connected with the control worm wheel 10; one end of the control worm 11 is connected with an operation hand wheel 12; in the forward rotation process of the control screw rod 9, the transverse positioning strips 6 are mutually close; during the reverse rotation of the control screw 9, the transverse positioning strips 6 are separated from each other (see fig. 3 and 6 of the description).
The purpose of this arrangement is that: when the locking screw 15 on the longitudinal positioning strip 8 is loosened, the transverse position of the transverse positioning strip 6 can be adjusted by pushing the longitudinal positioning strip 8; the relative position between the transverse positioning strips 6 is adjusted by means of turning the control worm 11.
The control worm 11 drives the two groups of transverse positioning strips 6 to synchronously draw together and separate from each other through the control screw rod 9; so that the middle position between the two groups of transverse positioning strips 6 and the center of the probe groove 2 are always kept on the same central line; when the probe is used for placing workpieces between the transverse positioning strips 6, the center point of the workpiece corresponds to the center of the probe groove 2, so that the probe in the probe groove 2 can always contact with the center point of the workpiece when in operation, and the probe can measure the contact of the center point of each workpiece when in operation, and the problem that the measurement error is large due to the fact that the measurement position of the workpiece cannot be accurately aligned in the existing detection mode is solved.
The longitudinal guide groove 5 and the transverse guide groove 7 are provided with marked scales (not shown in the drawing of the specification). The aim of setting the mark scale is that: when the device works, the distance between the two groups of transverse positioning strips 6 can be clearly marked through marking scales, so that the purpose of adapting the transverse positioning strips to the width of a workpiece is achieved.
When the rare earth NdFeB magnetic steel surface magnetic measurement clamp works, the positions of the longitudinal positioning strip 8 and the transverse positioning strip 6 are adjusted according to the length and the width of a workpiece; the spacing between the transverse locating strips 6 is consistent with the width of the workpiece, and the transverse distance between the end heads of the transverse locating strips 6 and the probe is consistent with the length of the workpiece. The workpiece is then placed between the lateral positioning bars 6 and pushed along the lateral positioning bars 6 so that its central point is in contact with the probe. Therefore, the purpose that the probe can measure the center point of the workpiece every time can be achieved. And because the measuring clamp can adjust the positions of the longitudinal positioning strips 8 and the transverse positioning strips 6, the measuring clamp can meet the detection requirements of various types of workpieces.
The rare earth neodymium iron boron magnetic steel meter magnetic measurement clamp is compact in structure and ingenious in design, can accurately position a workpiece during operation, enables the middle position of the workpiece to be measured every time when the detector works, solves the problem that the measurement error is large due to the fact that the workpiece measurement position cannot be accurately aligned in the existing detection mode, and is particularly suitable for the needs of the use of the rare earth neodymium iron boron magnetic steel meter magnetic measurement.
