Description

Technical Field

[0001] The present invention relates to the technical field of turning and milling groove detection, and particularly relates to a turning and milling groove detection device and a detection method thereof. Background Art

[0002] During the machining process, it is often necessary to machine grooves on long bar-shaped materials. In order to ensure that the machined bar stock has high-precision dimensions, shapes, and milling groove depths, it is necessary to detect the outer surface of the bar stock to detect the corresponding dimensions and whether the product meets the standards.

[0003] The existing straightness detection of bar stocks is generally manually measured with various measuring tools. It not only has a large measurement difficulty, takes a long time, but also has a low measurement efficiency and is difficult to meet the production requirements.

[0004] Even if some measurements are carried out mechanically, only several items can be measured. Different devices are required for separate measurement of each dimension, which affects the measurement efficiency and accuracy. For example, Chinese Patent CN201720714389.5 discloses a bar stock straightness detection device and a bar stock straightness detection system, which includes a workbench provided with at least one V-shaped groove and a sliding bracket that can move along the length direction of the V-shaped groove. The sliding bracket is connected with at least one dial indicator for detecting the bar stock in the V-shaped groove. The values measured by this patent are limited, and other dimensions need to be measured separately, which affects the measurement efficiency and effect.

[0005] Therefore, we propose a turning and milling groove detection device and a detection method thereof. Summary of the Invention

[0006] (1) Technical Problems to be Solved

[0007] Aiming at the deficiencies of the prior art, the present invention provides a turning and milling groove detection device and a detection method thereof, which overcome the deficiencies of the prior art, are reasonably designed, have a compact structure, and solve the problem of low efficiency of existing manual detection and mechanical detection. Through a simple structural combination, the present invention uniformly detects multiple dimensions of the bar stock, can measure some dimensions, and can also detect products that do not meet the dimensional requirements, improving the detection efficiency and making the detected products more in line with the standards, and has strong practicability.

[0008] (2) Technical Solutions

[0009] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0010] A turning and milling groove detection device, comprising a detection table, on which a connecting seat for placing a blank bar body is provided. A track is connected to the detection table, and a sliding seat is slidably connected to the track. A servo motor for driving is provided on the sliding seat, and a distance measuring sensor corresponding to the blank bar body is provided on the sliding seat.

[0011] The connecting seat includes a bottom plate, at least one support block is provided on the bottom plate, and two support wheels parallel to the blank bar body are provided on the support block.

[0012] Furthermore, the connecting seat further includes fixing blocks located at both ends of the bottom plate. A plurality of nuts are inserted into the fixing blocks, and one end of each nut abuts against the bottom plate.

[0013] Furthermore, a display screen is provided on the detection table.

[0014] Furthermore, the distance measuring sensor is slidably arranged on the sliding seat, and a positioning device is provided on the sliding seat.

[0015] A turning and milling groove detection method includes the following steps:

[0016] Step 1, place a calibration bar on the support wheels.

[0017] Step 2, preliminarily adjust the nuts so that the calibration bar is parallel to the track and the generatrix of the calibration bar is in the same straight line as the distance measuring sensor.

[0018] Step 3, start the servo motor and the distance measuring sensor. The servo motor drives the sliding seat to move towards one side of the calibration bar. At the same time, the distance measuring sensor will move along the generatrix of the calibration bar. When the light on the distance measuring sensor first touches the calibration bar, an initial measurement signal will be recorded on the display screen at this time. As the distance measuring sensor moves, the measurement signal will be displayed on the display screen. When the light of the distance measuring sensor leaves the calibration bar, a termination measurement signal will be recorded on the display screen at this time.

[0019] Step 4, when there is a deviation in the measured distance displayed on the display screen, it means that the distance measuring sensor is not aligned with the generatrix of the calibration bar.

[0020] Step 5, by repeating the above steps 2 to 4, align the distance measuring sensor with the generatrix of the calibration bar, and then subsequent measurement work can be carried out.

[0021] Step 6, place the blank bar body to be measured on the support wheels, and in particular, align the milling groove to be measured with the distance measuring sensor.

[0022] Step 7, same as step 3, start the servo motor and the distance measuring sensor to detect the blank bar body.

[0023] Furthermore, the calibration bar is a cylindrical blank bar.

[0024] Further, the sliding seat moves at a constant speed.

[0025] (III) Beneficial effects

[0026] The embodiment of the present invention provides a turning and milling groove detection device and its detection method, having the following beneficial effects:

[0027] 1. It can automatically detect the blank bar body, improve the detection efficiency, reduce manual operation, improve the detection accuracy, and has strong practicability. Place the blank bar body on the connecting seat, and then start the servo motor and the ranging sensor to automatically detect the blank bar body and improve the detection efficiency.

[0028] 2. It can automatically measure the length of the blank bar body. Through the initial measurement signal and the termination measurement signal, when the servo motor moves at a constant speed, the length of the blank bar body can be detected. When the data measured by the ranging sensor for the generatrix of the blank bar body is inconsistent with the data for the generatrix of the measurement calibration bar, it indicates that the blank bar body is unqualified. At the same time, by knowing the diameter of the calibration bar, the diameter of the support wheel, and the value of the distance between the two support wheels, the corresponding functional relationship is obtained to calculate the diameter of the blank bar body.

[0029] 3. It can automatically detect whether the diameter of the blank bar body meets the standard and measure the diameter of the blank bar body at the same time.

[0030] 4. It can automatically measure the position and depth of the milling groove. Within the data range displayed on the display screen, as the measurement data changes, the distance from the initial measurement signal to the milling groove can be accurately obtained to detect the specific position of the milling groove. At the same time, the depth data of the milling groove can be obtained to detect the depth of the milling groove and the flatness of the milling groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Referring to the attached Figures 1-4 , a turning and milling groove detection device includes a detection table 1, a connecting seat 2 is arranged on the detection table 1, the connecting seat 2 is used for holding a blank bar body 3, a track 4 is connected to the detection table 1, a sliding seat 5 is slidably connected to the track 4, a servo motor 7 for driving is arranged on the sliding seat 5, and a ranging sensor 6 corresponding to the blank bar body 3 is arranged on the sliding seat 5.

[0038] In this embodiment, as Figure 3 and 4 shown, the connecting seat 2 includes a bottom plate 2.1, at least one support block 2.2 is arranged on the bottom plate 2.1, and two support wheels 2.3 parallel to the blank bar body 3 are arranged on the support block 2.2, and the blank bar body 3 is placed between the two support wheels 2.3.

[0039] In this embodiment, as Figure 3 and 4 shown, the connecting seat 2 further includes fixing blocks 2.4 located at the left and right ends of the bottom plate 2.1, a plurality of nuts 2.5 are inserted into the fixing blocks 2.4, and one end of the nut 2.5 abuts against the bottom plate 2.1. The position of the bottom plate 2.1 can be adjusted through the nut 2.5, so that the blank bar body 3 and the ranging sensor 6 are located on the same horizontal line. Moreover, by adjusting the position of the bottom plate 2.1 through the nut 2.5, the applicable range can also be increased, which is convenient for detecting blank bars of different models.

[0040] In this embodiment, as Figure 1 and 2 shown, a display screen 8 is arranged on the detection table 1.

[0041] In this embodiment, as Figures 1-2 shown, the ranging sensor 6 is slidably arranged on the sliding seat 5, and a positioning device is arranged on the sliding seat 5, which can conveniently adjust the height of the sliding seat 5 and is convenient for detecting products of different heights.

[0042] A turning and milling groove detection method includes the following steps:

[0043] Step 1, place a calibration bar on the support wheels 2.3, and the calibration bar is a cylindrical blank bar.

[0044] Step 2: Initially adjust the nut 2.5 so that the calibration rod is parallel to the track 4 and the generatrix of the calibration rod is in the same straight line as the distance measuring sensor 6;

[0045] Step 3: Start the servo motor 7 and the distance measuring sensor 6. The servo motor 7 drives the sliding seat 5 to move towards one side of the calibration rod. At the same time, the distance measuring sensor 6 will move along the generatrix of the calibration rod. When the light on the distance measuring sensor 6 first touches the calibration rod, the initial measurement signal will be recorded on the display screen 8 at this time. As the distance measuring sensor 6 moves, the measurement signal will be shown on the display screen 8. When the light of the distance measuring sensor 6 leaves the calibration rod, the termination measurement signal will be recorded on the display screen 8 at this time.

[0046] Step 4: When there is a deviation in the measured distance shown on the display screen 8, it indicates that the distance measuring sensor 6 is not aligned with the generatrix of the calibration rod.

[0047] Step 5: By repeating the above steps 2 to 4, align the distance measuring sensor 6 with the generatrix of the calibration rod, and then subsequent measurement work can be carried out.

[0048] Step 6: Place the to-be-tested rod body 3 on the support wheel 2.3, and particularly align the to-be-milled groove to be measured with the distance measuring sensor 6.

[0049] Step 7: Similar to Step 3, start the servo motor 7 and the distance measuring sensor 6 to detect the rod body 3.

[0050] 1. When the data measured by the distance measuring sensor 6 for the generatrix of the rod body 3 is inconsistent with the data measured for the generatrix of the calibration rod, it indicates that there is a non-conforming situation with the rod body 3. At the same time, by knowing the diameter of the calibration rod, the diameter of the support wheel, and the value of the distance between the two support wheels, the corresponding functional relationship is obtained to calculate the diameter of the rod body 3.

[0051] 2. When the light on the distance measuring sensor 6 first touches the rod body 3, the initial measurement signal will be recorded on the display screen 8 at this time. As the distance measuring sensor 6 moves, the measurement signal will be shown on the display screen 8 until the light of the distance measuring sensor 6 leaves the rod body 3. At this time, the termination measurement signal will be recorded on the display screen 8. With the servo motor moving at a constant speed, the length of the rod body 3 can be detected through the initial measurement signal and the termination measurement signal.

[0052] 3. Within the data range shown on the display screen 8, as the measurement data changes, the distance from the initial measurement signal to the milled groove can be accurately obtained, the specific position of the milled groove can be detected, and at the same time, the depth data of the milled groove can be obtained to detect the depth of the milled groove and the flatness of the milled groove.

[0053] Thus, it is possible to obtain whether the detection rod body 3 meets the standards and the specific values on the discharge rod body 3, which is convenient for subsequent processing and adjustment.
