Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of M value quick detection device of blade, belong to the technical field of tolerance detection. BACKGROUND

[0002] In the field of tool manufacturing and processing, M value is an important parameter to measure the repeat positioning accuracy and machining accuracy of blade, and its accurate measurement and judgment are crucial to ensure product quality. The definition of M value varies depending on the shape of the blade: for equilateral triangle blades and other odd-sided blades, M value is defined as the perpendicular distance from the measured blade tip to its opposite side; while for circular blades, M value is directly equivalent to its diameter. For these regular-shaped blades, M value can be directly and accurately measured by commonly used measuring tools, such as micrometer, vernier caliper or height gauge, etc.

[0003] However, for square blades, rhombus blades and other large blades with even sides, the determination of M value is relatively complex, it is equal to the minimum distance from the measured blade tip to the inscribed circle, this feature makes direct measurement relatively difficult, because it is necessary to accurately determine the position of the inscribed circle and measure the shortest distance to the blade tip, this measurement process not only requires high precision, but also increases the complexity and time cost of operation.

[0004] Currently, the existing measurement method is still aimed at obtaining the accurate value of M value, and by comparing the pre-set qualified range to judge whether the product is qualified. Although this method is accurate, in actual production environment, M value is often a range of allowable fluctuations, rather than a fixed value. This means that even if M value deviates slightly but within the qualified range, the product should still be considered qualified. However, the traditional measurement method requires detailed measurement of each blade, which not only consumes time and effort, but also in mass production environment, detection efficiency becomes the key factor restricting production efficiency.

[0005] Therefore, there is an urgent need for a detection device that can accurately and quickly determine whether M value is within the qualified range, to replace the existing detailed measurement process.

[0029] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0030] Example 1:

[0031] like Figure 1 As shown, a rapid detection device for the M value of a cutting blade includes a base 1, a slide 3, a maximum limit switch 6, and a minimum limit switch 7. The base 1 is provided with a slide rail 9, and the slide 3 is slidably mounted on the base 1 via the slide rail 9. The slide 3 is provided with a measuring platform 2. The maximum limit switch 6 and the minimum limit switch 7 are located at the maximum limit dimension height and the minimum limit dimension height of the cutting blade being measured, respectively.

[0032] In addition, in this embodiment:

[0033] A vertical plate is provided on one side of the slide block 3, and the maximum limit switch 6 and the minimum limit switch 7 are spaced apart on the vertical plate. The vertical plate has two elongated holes, corresponding to the installation positions of the maximum limit switch 6 and the minimum limit switch 7, respectively.

[0034] In this embodiment, both the maximum limit switch 6 and the minimum limit switch 7 employ L-shaped limit blocks. The side plate of the L-shaped limit block is fixed in the elongated hole of the upright plate by bolts 8, while the bottom plate of the L-shaped limit block restricts the passage of the tested blade. Using L-shaped limit blocks not only facilitates installation on the upright plate but also makes it easy to observe and determine whether the blade has passed the test.

[0035] The maximum limit switch 6 is fixed to the upright plate in a height-adjustable manner, and the minimum limit switch 7 is fixed to the upright plate in a height-adjustable manner.

[0036] The heights of the maximum limit switch 6 and the minimum limit switch 7 can be flexibly adjusted according to the limit dimensions of different blades based on their M-value, thereby adapting to the inspection needs of blades of different specifications and types.

[0037] The measuring table 2 is provided with a recess for placing the measured blade, and the recess is shaped to match the shape of the measured blade.

[0038] The detection device further comprises a scale arranged beside the vertical plate. The detection personnel can visually read and record the M value detection result of the blade through the scale, and can also adjust the height of the maximum limit stopper 6 and the minimum limit stopper 7 through the scale, thereby improving the detection efficiency.

[0039] Taking the measured rhombic blade 5 as an example, how to use the detection device of the utility model to detect whether it is qualified is described in detail. In this embodiment, the V-shaped groove 4 matched with the shape of the rhombic blade 5 is used as the recess. Of course, according to actual needs, the recess can also be in other shapes such as semicircular, rectangular, trapezoidal or polygonal. In this example, the opening angle of the V-shaped groove 4 is 80° to adapt to the shape characteristics of the rhombic blade 5.

[0040] Suppose the M value of the rhombic blade 5 is m, and the tolerance range is ±x. The specific measurement steps are as follows:

[0041] S1, calibration step:

[0042] S1.1, select a rhombic reference block gauge A with an opening angle of 80°, and set its M value to m+x (i.e. the upper limit of the tolerance range). Place the reference block gauge A in the V-shaped groove 4, and push the sliding seat 3 along the sliding rail 9 until the reference block gauge A reaches below the maximum limit stopper 6.

[0043] S1.2, adjust the height of the maximum limit stopper 6 so that its bottom is in contact with the reference block gauge A. Then, tighten the bolt 8 to fix the position of the maximum limit stopper 6.

[0044] S1.3, select another rhombic reference block gauge B, and set its M value to m-x (i.e. the lower limit of the tolerance range). Place the reference block gauge B in the V-shaped groove 4 according to the same method as steps S1.1 and S1.2, and adjust the height of the minimum limit stopper 7.

[0045] S2, measurement step:

[0046] S2.1, place the rhombic blade 5 to be measured in the V-shaped groove 4, and ensure that the blade is stable and will not slide.

[0047] S2.2, push the sliding seat 3 along the sliding rail 9 to move the blade below the maximum limit stopper 6 and the minimum limit stopper 7 in turn.

[0048] S2.3, according to the situation of the blade passing through the limit stopper, judge whether the M value of the blade is within the tolerance range:

[0049] If the blade can pass under the maximum limit stopper 6 and the minimum limit stopper 7, it means that the M value of the blade is too small, exceeding the lower limit of the tolerance range, and thus the size is unqualified.

[0050] If the blade fails to pass under the maximum limit stopper 6, it means that the M value of the blade is too large, exceeding the upper limit of the tolerance range, and thus the size is unqualified.

[0051] If the blade can pass under the maximum limit stopper 6 but fails to pass under the minimum limit stopper 7, it means that the M value of the blade is within the tolerance range, and thus the size is qualified.

[0052] The detection device of the utility model can significantly improve the detection efficiency in large-scale detection, while ensuring the accuracy of the detection results, thereby meeting the demand of modern industry for high-quality and high-efficiency production.

[0053] Embodiment two:

[0054] This embodiment is different from embodiment one, mainly in the form and installation method of the maximum limit stopper 6 and the minimum limit stopper 7. In this example, the two limit stoppers adopt the form of probes or micrometers and are installed on the vertical plate.

[0055] Taking the first probe and the second probe as examples, the maximum limit stopper 6 and the minimum limit stopper 7 are described as follows:

[0056] During calibration, the same diamond reference block gauge A with an opening angle of 80° is used as in embodiment one, and the M value thereof is set as the upper limit m+x of the tolerance range. The reference block gauge A is placed in the V-shaped groove 4, and then the sliding seat 3 is pushed to move along the sliding rail 9 until the reference block gauge A reaches under the first probe. Then, the probe of the first probe is adjusted to be in contact with the reference block gauge A, and the first probe is calibrated to zero.

[0057] Then, another diamond reference block gauge B is selected, and the M value thereof is set as the lower limit m-x of the tolerance range. According to the same method of calibrating the first probe, the reference block gauge B is placed in the V-shaped groove 4, and the second probe is calibrated to zero.

[0058] During measurement, the diamond blade 5 to be measured is placed in the V-shaped groove 4 and ensured to be stable and not to slide. Then, the sliding seat 3 is pushed to move along the sliding rail 9, so that the blade passes under the first probe and the second probe in turn.

[0059] According to the passing condition of the blade through the probes, it can be judged whether the M value of the blade is within the tolerance range:

[0060] If the blade can pass the first probe and the second probe smoothly, and the readings of the two probes are not changed, it indicates that the M value of the blade is too small, exceeding the lower limit of the tolerance range, and thus the size is unqualified.

[0061] If the blade can pass the first probe smoothly, and the reading of the first probe is changed when passing the second probe, it indicates that the M value of the blade is too large, exceeding the upper limit of the tolerance range, and thus the size is unqualified.

[0062] If the blade can pass the first probe smoothly, and the reading of the first probe is changed when passing the second probe, it indicates that the M value of the blade is too large, exceeding the upper limit of the tolerance range, and thus the size is unqualified.

[0063] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
