[0017] A method for using a multifunctional integrated workpiece measuring device, the method specifically comprising the following steps:

[0018] Step 1: Place the cylindrical workpiece between the first slider and the second slider so that the workpiece is supported by the first slider and the second slider, then rotate the lead screw, the lead screw moves through the thread between the lead screw and the vertical plate, thereby driving the first slider and the second slider to move, and adjust the distance between the first slider and the second slider so that the workpiece can contact the probe of the dial indicator;

[0019] Step 2: Place the cylindrical workpiece to be measured inside the feeding box and rotate the screw. The screw pushes the ball head to move through the thread between the screw and the side wall of the feeding box, so that the ball head pushes the rotating plate to rotate through the rotating shaft, and the minimum spacing between the two rotating plates is adjusted to 1.1-1.3 times the diameter of the cylindrical workpiece, so that the gap between the two rotating plates can only pass one cylindrical workpiece;

[0020] Step 3: The cylindrical workpiece falls into the trough of the discharge roller through the gap between the two rotating plates in the feeding box, and the motor is started, and its output shaft drives the discharge roller to rotate, so that the workpiece in the trough falls from the bottom of the feeding box;

[0021] Step 4: The fallen workpiece falls between the first slider and the second slider. When there is an error in the diameter of each workpiece, the depth of each workpiece in the "V"-shaped groove between the first slider and the second slider is different, and the value of the dial indicator will change. The camera is connected to the external display screen, and the value of the dial indicator can be observed through the display screen. By recording the measured value of each workpiece, the diameter error between each workpiece can be obtained;

[0022] Step 5: After recording the values, start the single-axis cylinder. The output shaft of the single-axis cylinder pushes the workpiece to move between the first slider and the second slider. At this time, the workpiece will move at the top of the probe of the dial indicator. By observing the value changes of the dial indicator, the surface flatness of the workpiece can be obtained.

[0023] Step 6: When the single-axis cylinder pushes the workpiece to move, its output shaft drives the connecting rod to move, and the connecting rod drives the digital display cursor to move in the slot through the connector. When one end of the workpiece is pushed to contact the baffle, it stops. At this time, the length of the workpiece is equal to the distance from the digital display cursor to the rear surface of the baffle, which is the distance between the "0" scale of the ruler and the digital display cursor. The digital display cursor measures the length of the workpiece and displays it;

[0024] Step 7: After measuring the length, the electric telescopic rod works, and its output shaft drives the baffle to move downward. The top surface of the baffle is lower than or flush with the top surface of the inclined plate. At this time, the single-axis cylinder works again to push the workpiece onto the inclined plate, and then falls into the receiving box under the guidance of the inclined plate;

[0025] Step 8: The double-axis cylinder works, and its output shaft passes through the through hole at the bottom of the receiving box to push the receiving plate to the upper position inside the receiving box. When the workpiece falls, it receives the workpiece. When the height of the workpiece is close to the top surface of the receiving box, the output shaft of the double-axis cylinder lowers its height, so that the height of the receiving plate is lowered, and the workpiece is received layer by layer. When the receiving box is full of workpieces, the receiving box can be taken out and replaced with an empty one.

[0026] The beneficial effects of the present invention are as follows:

[0027] By setting a diameter error measurement structure, when the cylindrical workpiece is located between the first slider and the second slider, it is guided to the center position of the two sliders by the first slider and the second slider, so that the center line of the cylindrical workpiece is perpendicular to the probe center of the dial indicator, which has the function of automatic centering of the workpiece and improves the measurement accuracy; when there is an error in the diameter of each workpiece, the value of the dial indicator will change, and the diameter error between each workpiece can be obtained by recording the measured value of each workpiece. Compared with the traditional manual diameter measurement method, it is more convenient and faster, suitable for batch detection, and improves the functionality of the entire measuring device; and the spacing between the first slider and the second slider can be adjusted by rotating the screw rod, which is convenient for cylindrical workpieces of various diameters and has a wider range of applications;

[0028] By setting a feeding structure to cooperate with a diameter error measuring structure, a feeding box is set at the center upper position between the first slider and the second slider to store materials, and the materials are fed between the first slider and the second slider one by one in a feeding manner, thereby achieving the purpose of automatic feeding, reducing the time and energy of manual feeding, and eliminating the need for frequent feeding operations;

[0029] By setting up the unloading structure, the single-axis cylinder works, and its output shaft pushes the workpiece to move, so that the workpiece is pushed out and falls into the upper part of the inclined plate, completing the unloading work, reducing the time of manual unloading, and making it more convenient to use; by coordinating the unloading structure with the feeding structure and the diameter error measurement structure, an integrated working mode of feeding, measuring and unloading is realized, the work efficiency is high, the frequency of manual operation is effectively reduced, and time and labor are saved; and in the unloading process, the surface of the workpiece will contact the probe of the dial indicator, and the surface flatness data of the workpiece can be obtained by observing the value change of the dial indicator, thereby improving the functionality of the measuring device;

[0030] By setting up a material receiving box in conjunction with a double-axis cylinder and a connecting plate, during the unloading process, the output shaft of the double-axis cylinder can push the connecting plate to move downward continuously, reducing the height difference of the falling material, thereby avoiding the phenomenon that the material is damaged when falling, and improving the protection effect of the material;

[0031] By setting up a length measurement structure in conjunction with the unloading structure, during the unloading process, the single-axis cylinder will push the digital display cursor to move. When the workpiece is blocked by the baffle, the digital display cursor can display the length of the workpiece, realizing the dual functions of workpiece diameter error and length measurement, making the entire measuring equipment more powerful.

[0042] The probe of the dial indicator 10 is set at the center position between the first slider 6 and the second slider 7, and the opposite sides of the first slider 6 and the second slider 7 are set as inclined surfaces. When the cylindrical workpiece is located between the first slider 6 and the second slider 7, it is guided to the center position of the two sliders by the first slider 6 and the second slider 7, so that the center line of the cylindrical workpiece is perpendicular to the probe center of the dial indicator 10.

[0043] In this embodiment, a feeding structure 12 is provided on the upper portion of the vertical plate 8 , and a discharging structure 16 is provided at the front center of the base 1 .

[0044] The feeding structure 12 cooperates with the unloading structure 16 to reduce the steps of manual operation in the whole detection process, saving manpower and also increasing work efficiency.

[0048] The cylindrical workpieces are stored in the feeding box 13 and are fed out one by one through the bottom of the feeding box 13, without the need for frequent manual addition of materials, thus reducing the working frequency and saving manpower.

[0049] In this embodiment, the feeding structure 12 also includes an axle seat 32, a rotating shaft 33, a rotating plate 34, a screw 35, a ball head 36, a discharge roller 37 and a material trough 38. The axle seat 32 is installed on the inner wall of the feeding box 13, the rotating plate 34 is movably connected to the axle seat 32 through the rotating shaft 33, the screw 35 passes through the side wall of the feeding box 13, the ball head 36 is installed at one end of the screw 35, the discharge roller 37 is rotatably connected to the inside of the feeding box 13 near the bottom, and the material trough 38 is opened on the outer surface of the discharge roller 37.

[0050] The motor 20 works to drive the discharge roller 37 to rotate, and the discharge roller 37 can rotate the materials in the trough 38 to face the bottom of the feeding box 13, while ensuring the feeding of the materials one by one, it also achieves the purpose of stable discharge and improves the working stability.

[0051] In this embodiment, the shaft seat 32, the rotating shaft 33, the rotating plate 34, the screw rod 35 and the ball head 36 constitute an adjustment structure. The adjustment structure is symmetrically arranged in two groups, and the two rotating plates 34 are arranged in a "V" shape.

[0052] By rotating the screw 35 and pushing the rotating plate 34 to rotate via the rotating shaft 33 , the distance between the two rotating plates 34 can be adjusted, so as to be suitable for materials of various diameters and improve the scope of application.

[0053] In this embodiment, there are four material troughs 38 in a circular array, and the material troughs 38 are arranged in an inverted trapezoidal shape, and the discharge roller 37 is fixedly connected to the output shaft of the motor 20.

[0054] The four material troughs 38 can store two materials at the same time. Every time the unloading roller 37 rotates 90 degrees, unloading and loading can be performed once, so that the feeding action during operation is faster.

[0055] In this embodiment, the unloading structure 16 includes an inclined plate 17, a baffle 18, a support plate 21, a single-axis cylinder 22 and an electric telescopic rod 29. The inclined plate 17 is installed at the front center position of the base 1, the baffle 18 runs through the inclined plate 17, the support plate 21 is installed at the rear center position of the base 1, the single-axis cylinder 22 is installed on the upper part of the support plate 21, and the electric telescopic rod 29 is installed at the bottom of the reinforcement plate 3 perpendicular to the baffle 18, and the output shaft of the electric telescopic rod 29 is fixedly connected to the baffle 18.

[0056] The single-axis cylinder 22 works, and its output shaft pushes the workpiece to move, so that the workpiece is pushed out and falls into the upper part of the inclined plate 17, completing the unloading work, reducing the time of manual unloading, and making it more convenient to use.

[0057] In this embodiment, the unloading structure 16 also includes a material receiving box 19, a dual-axis cylinder 30 and a connecting plate 31. The material receiving box 19 is placed on one side of the upper part of the reinforcement plate 3, the dual-axis cylinder 30 is installed on one side of the bottom of the reinforcement plate 3, and the connecting plate 31 is placed inside the material receiving box 19. A through hole is opened on the lower surface of the material receiving box 19, and the output shaft of the dual-axis cylinder 30 passes through the reinforcement plate 3.

[0058] When the material falls onto the upper part of the inclined plate 17, it will fall into the material receiving box 19 through the guidance of the inclined plate 17. The output shaft of the double-axis cylinder 30 pushes the receiving plate 31 to the top position in the material receiving box 19. Every time a layer of material is received, the output shaft of the double-axis cylinder 30 drives the height of the receiving plate 31 to decrease, avoiding the phenomenon of damage caused by falling from a high place, realizing automatic material receiving while improving the protection of the material.

[0059] In this embodiment, a length measuring structure 23 is provided at the bottom of the feeding box 13, and the length measuring structure 23 includes a ruler 24, a connecting rod 25, a digital display cursor 26, a slot 27 and a connector 28. The ruler 24 is installed at one side of the bottom of the feeding box 13, the connecting rod 25 is installed on the outside of the output shaft of the single-axis cylinder 22, the digital display cursor 26 is installed at one end of the connecting rod 25, the slot 27 is opened on one side surface of the ruler 24, the connector 28 is slidably connected to the inside of the slot 27, the connector 28 is fixedly connected to the digital display cursor 26, and the "0" scale of the ruler 24 is vertically aligned with the rear surface of the baffle 18.

[0060] While unloading, the single-axis cylinder 22 will push the digital display cursor 26 to move, and with the limit of the baffle 18, the length of the workpiece can be measured, which effectively improves the functionality of the measuring device. While the workpiece is being pushed, the surface of the workpiece contacts the probe of the dial indicator 10, and the flatness of the workpiece surface can be obtained by observing the numerical changes of the dial indicator 10.

[0061] A method for using a multifunctional integrated workpiece measuring device, the method specifically comprising the following steps:

[0062] Step 1: Place the cylindrical workpiece between the first slider 6 and the second slider 7 so that the workpiece is supported by the first slider 6 and the second slider 7, and then rotate the screw rod 9, which moves through the thread between the screw rod 9 and the vertical plate 8, thereby driving the first slider 6 and the second slider 7 to move, and adjust the distance between the first slider 6 and the second slider 7 so that the workpiece can contact the probe of the dial indicator 10;

[0063] Step 2: Place the cylindrical workpiece to be measured inside the feeding box 13, and rotate the screw 35. The screw 35 pushes the ball head 36 to move through the thread between the screw 35 and the side wall of the feeding box 13, so that the ball head 36 pushes the rotating plate 34 to rotate through the rotating shaft 33, and the minimum spacing between the two rotating plates 34 is adjusted to 1.1-1.3 times the diameter of the cylindrical workpiece, so that the gap between the two rotating plates 34 can only pass one cylindrical workpiece;

[0064] Step 3: The cylindrical workpiece falls into the trough 38 of the discharge roller 37 through the gap between the two rotating plates 34 in the feeding box 13, and the motor 20 is started to work, and its output shaft drives the discharge roller 37 to rotate, so that the workpiece in the trough 38 falls from the bottom of the feeding box 13;

[0065] Step 4: The fallen workpiece falls between the first slider 6 and the second slider 7. When there is an error in the diameter of each workpiece, the depth of each workpiece in the "V"-shaped groove between the first slider 6 and the second slider 7 is different, and the value of the dial indicator 10 will change. The camera 11 is connected to the external display screen, and the value of the dial indicator 10 can be observed through the display screen. By recording the measured value of each workpiece, the diameter error between each workpiece can be obtained;

[0066] Step 5: After recording the values, start the single-axis cylinder 22 to work. The output shaft of the single-axis cylinder 22 pushes the workpiece to move between the first slider 6 and the second slider 7. At this time, the workpiece moves at the top of the probe of the dial indicator 10. By observing the value change of the dial indicator 10, the surface flatness of the workpiece can be obtained;

[0067] Step 6: When the single-axis cylinder 22 pushes the workpiece to move, its output shaft drives the connecting rod 25 to move, and the connecting rod 25 drives the digital display cursor 26 to move in the slot 27 through the connector 28. When one end of the workpiece is pushed to contact the baffle 18, it stops. At this time, the length of the workpiece is equal to the distance from the digital display cursor 26 to the rear surface of the baffle 18, which is the distance between the "0" scale of the ruler 24 and the digital display cursor 26. The digital display cursor 26 measures the length of the workpiece and displays it;

[0068] Step 7: After measuring the length, the electric telescopic rod 29 works, and its output shaft drives the baffle 18 to move downward, and the top surface of the baffle 18 is lower than or flush with the top surface of the inclined plate 17. At this time, the single-axis cylinder 22 works again to push the workpiece onto the inclined plate 17, and then falls into the receiving box 19 under the guidance of the inclined plate 17;

[0069] Step eight: The double-axis cylinder 30 works, and its output shaft passes through the through hole at the bottom of the receiving box 19 to push the receiving plate 31 to the upper position inside the receiving box 19, and receives the workpiece when it falls. When the height of the workpiece is close to the top surface of the receiving box 19, the output shaft of the double-axis cylinder 30 lowers its height, so that the height of the receiving plate 31 is lowered, and the workpiece is received layer by layer. When the receiving box 19 is filled with workpieces, the receiving box 19 is taken out and replaced with an empty one.

10. A method for using the multifunctional integrated workpiece measuring device according to claim 9, characterized in that: The method specifically comprises the following steps: Step 1: Place the cylindrical workpiece between the first slider (6) and the second slider (7) so that the workpiece is supported by the first slider (6) and the second slider (7), then rotate the screw rod (9), the screw rod (9) moves through the thread between the screw rod (9) and the vertical plate (8), thereby driving the first slider (6) and the second slider (7) to move, and adjust the distance between the first slider (6) and the second slider (7) so that the workpiece can contact the probe of the dial indicator (10); Step 2: Place the cylindrical workpiece to be measured inside the feeding box (13), and rotate the screw (35), so that the screw (35) pushes the ball head (36) to move through the thread between the screw and the side wall of the feeding box (13), so that the ball head (36) pushes the rotating plate (34) to rotate through the rotating shaft (33), and the minimum spacing between the two rotating plates (34) is adjusted to 1.1-1.3 times the diameter of the cylindrical workpiece, so that the gap between the two rotating plates (34) can only pass one cylindrical workpiece; Step 3: The cylindrical workpiece falls into the trough (38) of the discharge roller (37) through the gap between the two rotating plates (34) in the feeding box (13), and the motor (20) is started to work, and its output shaft drives the discharge roller (37) to rotate, so that the workpiece in the trough (38) falls from the bottom of the feeding box (13); Step 4: The fallen workpiece falls between the first slider (6) and the second slider (7). When there is an error in the diameter of each workpiece, the depth of each workpiece in the "V"-shaped groove between the first slider (6) and the second slider (7) is different, and the value of the dial indicator (10) will change. The camera (11) is connected to an external display screen, and the value of the dial indicator (10) can be observed through the display screen. By recording the measured value of each workpiece, the diameter error between each workpiece can be obtained; Step 5: After recording the values, the single-axis cylinder (22) is started to work. The output shaft of the single-axis cylinder (22) pushes the workpiece to move between the first slider (6) and the second slider (7). At this time, the workpiece moves at the top of the probe of the dial indicator (10). By observing the value change of the dial indicator (10), the surface flatness of the workpiece can be obtained; Step 6: When the single-axis cylinder (22) pushes the workpiece to move, its output shaft drives the connecting rod (25) to move, and the connecting rod (25) drives the digital display cursor (26) to move in the slot (27) through the connector (28). When one end of the workpiece is pushed to contact the baffle (18), it stops. At this time, the length of the workpiece is equal to the distance from the digital display cursor (26) to the rear surface of the baffle (18), which is the distance between the "0" scale of the ruler (24) and the digital display cursor (26). Then the digital display cursor (26) measures the length of the workpiece and displays it; Step 7: After measuring the length, the electric telescopic rod (29) works, and its output shaft drives the baffle (18) to move downward, and the top surface of the baffle (18) is lower than or flush with the top surface of the inclined plate (17). At this time, the single-axis cylinder (22) works again to push the workpiece onto the inclined plate (17), and then falls into the material receiving box (19) under the guidance of the inclined plate (17); Step 8: The double-axis cylinder (30) works, and its output shaft penetrates the through hole at the bottom of the receiving box (19) to push the receiving plate (31) to move to the upper position inside the receiving box (19), and receives the workpiece when it falls. When the height of the workpiece approaches the top surface of the receiving box (19), the output shaft of the double-axis cylinder (30) lowers its height, so that the height of the receiving plate (31) is lowered, and the workpiece is received layer by layer. When the receiving box (19) is filled with workpieces, the receiving box (19) is taken out and replaced with an empty one.
