Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile parts detection and relates to a straight slot width detection measuring tool. Background Art
[0002] The bracket is a key part of the automobile brake. The part is designed with two straight grooves of the same size to accommodate the brake pad and guide it during braking. If the width of the groove is too small, the sliding resistance of the brake pad will increase, which will directly affect the braking effect. However, if the size is too large, the brake pad gap will be too large and produce abnormal noise, so the dimensional accuracy needs to be controlled within 0.1 to 0.15mm; in addition, since the basic size of the groove width is relatively large, the ordinary car is generally 150mm to 250mm. For the detection of this width, the traditional measurement method is to use a vernier caliper. Due to the fact that manual measurement cannot ensure that the caliper is perpendicular to the measured surface of the groove and the measurement force, etc., the detection results are often unreliable, with an error rate of 8 to 12%.

When measuring, the workpiece 7 can rely on the inclination force to eliminate the measurement gap and improve the measurement accuracy; M3 is the width of the block to be calibrated, which is also the reference size for detection; the detection seat 3 is mainly used to position the workpiece, and is mounted on the base by screw connection. The width of the seat 3 and the gap between the workpiece to be measured is 0.1mm, which ensures good guidance of the workpiece during detection; the measuring tool dial indicator 5 is installed in the seat 4, and the seat 4 is installed at the bottom of the base 2 by screw connection; the core shaft 12 is installed in the horizontal hole at the bottom of the detection seat 3, and the detection rod 12 is installed in the upper longitudinal hole of the detection seat 3; the detection seat 3 and the seat 4 are provided with a vertical through groove, and the rotating arm 9 is installed in the groove and can rotate around the core shaft 12; the spring 8 and the stop screw 11 are installed in the hole of the seat 4; the upper part of the rotating arm 9 is designed to be arc-shaped and is installed in the through groove in the middle of the detection rod 12.
[0027] In this embodiment, the calibration block 6 is used to calibrate the dial indicator to zero during measurement.
[0028] In this embodiment, the rotating arm and the core shaft, as well as the detection rod and the detection seat hole, are matched with H6 level precision, and the dial indicator 8 adopts an ordinary dial indicator. The detection device has low cost and can achieve an accuracy of 0.01mm.
[0029] In this embodiment, M1 and M2 are two groove width dimensions of the measured element, and the two are required to be equal in size.
[0030] In this implementation example, Figure 6 This is the internal structure diagram of the utility model. For the purpose of clear display, the base 2, the detection base 3, the dial base 4, the dial indicator 5, the calibration block 6 and the related screws are hidden.
[0031] When the utility model is used, the following steps are included:
[0032] The first step is to install the calibration block on the detection seat 3, with one end of its groove close to the detection reference surface B1, and the other end of its groove aligned with the detection rod 12, and turn the dial to align the dial indicator pointer with the dial scale zero line to perform zero calibration;
[0033] In the second step, remove the calibration block 6 and install the workpiece in the detection seat 3 according to the position shown in the figure, so that one end face of the workpiece groove (detection element M1) is close to the detection reference surface B1, and the other end face of the groove is aligned with the detection rod 12;
[0034] Step 3: The difference between the actual value of the dial indicator and the zero value is the test result of M1;
[0035] Step 4: Move the workpiece longitudinally so that one end surface of the groove of the workpiece (detection element M2) is close to the detection reference surface B1, and the other end surface of the groove is aligned with the detection rod 12;
[0036] Step 5: The difference between the actual value of the dial indicator and the zero value is the test result of M2.
[0037] In this embodiment, when the workpiece is moved longitudinally, the groove surface of the workpiece compresses the detection rod 12 to make it move inward, and the rotating arm 9 in the middle groove of the detection rod 12 is acted upon by the force and moves with the detection rod. At this time, the rotating arm 9 rotates around the core shaft 10, thereby affecting the value of the dial indicator.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
