DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantage of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be described clearly and completely in conjunction with the drawings in the utility model embodiment below, and obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiment of the utility model. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the scope of protection of the utility model.

[0020] Please refer to Figures 1 to 4 The utility model provides a technical scheme: a four side milling automatic centering measuring device, including measuring platform 1, the upper surface of measuring platform 1 is through and is set up with round groove 101, the coaxial setting of round groove 101 has placing tray 2, the lower portion of measuring platform 1 is provided with equipment box 3, and the upper surface between equipment box 3 and the bottom surface of measuring platform 1 is fixedly connected through a plurality of supports 4, and equipment box 3 is internally provided with by lifting rotary mechanism, and lifting rotary mechanism is connected with the bottom surface of placing tray 2, and the upper surface of measuring platform 1 is fixedly installed with a plurality of annularly and evenly distributed laser sensors 5 at the circumference of round groove 101, and the front side surface of equipment box 3 is provided with control display module 6, and lifting rotary mechanism and a plurality of laser sensors 5 are electrically connected with control display module 6.

[0021] Please refer to Figure 2 And Figure 3 Lifting rotary mechanism includes gear ring 301, and the upper surface of equipment box 3 is provided with cylindrical structure protruding part, gear ring 301 is rotatably connected on the outer wall of protruding part, one end of telescopic connecting rod 302 is fixedly connected on the both sides of the upper surface of gear ring 301, the other end of two telescopic connecting rods 302 is fixedly connected on the bottom surface of placing tray 2, gear ring 301 is meshedly connected with one side gear 303, gear 303 is fixedly sleeved on the one end of motor 304 output shaft, and motor 304 is fixedly installed in the inside of equipment box 3, and the one end of its output shaft extends to the outside of equipment box 3 through the through hole.

[0022] The cylindrical structure protruding part on the upper surface of the equipment box 3 serves as the rotating support of the gear ring 301, and the telescopic connecting rods 302 on both sides of the gear ring 301 are connected to the placement disc 2. When the motor 304 fixed in the equipment box 3 is started, the gear 303 at one end of the output shaft is driven to rotate, the gear 303 meshes with the gear ring 301, and the gear ring 301 is rotated around the outer wall of the protruding part, and then the placement disc 2 is driven to rotate synchronously through the telescopic connecting rods 302, so that the measurement angle of the placement disc 2 can be adjusted as needed. Drive the placement disc 2 to rotate at a relatively stable speed, and the distance between the workpiece placed on the surface of the placement disc 2 and the several laser sensors 5 is continuously detected in the circumferential direction. The outer wall contour size of the workpiece is scanned by calculating the distance, so that the center position of the workpiece is measured by using the control display module 6, and the center coordinates of the workpiece are transmitted to the four-face milling equipment to complete the centering measurement work.

[0023] Further, the lifting and rotating mechanism further comprises a second cylinder 305, the output shaft of the second cylinder 305 is extended to the outside of the equipment box 3 through the through hole formed in the top surface of the protruding part and is rotatably connected to the bottom surface of the placement disc 2.

[0024] The second cylinder 305 is fixed in the measurement table 1, and the output shaft of the second cylinder 305 extends to the outside of the equipment box 3 through the through hole in the top of the protruding part and is rotatably connected to the bottom of the placement disc 2. When it is necessary to adjust the height of the placement disc 2, the second cylinder 305 is extended and retracted, and the rotating and lifting structure composed of the gear ring 301 and the telescopic connecting rods 302 cooperates to accurately change the height position of the placement disc 2. When the workpiece has an irregular outer wall, the height of the placement disc 2 can be adjusted to enable the several laser sensors 5 to measure the distance at different heights of the outer wall of the workpiece, so as to scan the three-dimensional contour and specifications of the workpiece, improve the accuracy of finding the center coordinates, and reduce the use limitations.

[0025] Please refer to Figure 1 and Figure 4 The upper surface of the measurement table 1 is also provided with a limiting mechanism and a dust removal mechanism on both sides.

[0026] The limiting mechanism and the dust removal mechanism are respectively arranged on both sides of the upper surface of the measurement table 1. The limiting mechanism tightly constrains the workpiece to avoid the problem of reducing the measurement accuracy caused by the displacement of the workpiece position during the rotation and lifting of the placement disc 2. The dust removal mechanism removes the dust on the surface of the placement disc 2 after the completion of the centering and milling work, so as to avoid the influence of the debris generated during the milling process on the next distance measurement of the laser sensor 5.

[0027] Further, the limiting mechanism comprises an L-shaped connecting rod 102, one end of the L-shaped connecting rod 102 is rotatably connected with a pressing limiting block 103, and the other end of the L-shaped connecting rod 102 is rotatably connected with the piston rod of the first cylinder 104. The first cylinder 104 is fixedly installed on one side of the upper surface of the measurement table 1.

[0028] The pressing limiting block 103 at one end of the L-shaped connecting rod 102 is in contact with the workpiece, and the other end is rotationally connected with the piston rod of the first air cylinder 104 fixed on the measuring table 1. When the piston rod of the first air cylinder 104 extends or retracts, the L-shaped connecting rod 102 is driven to rise or fall, thereby driving the pressing limiting block 103 to press or release the workpiece, so that rapid and reliable limiting operation is realized. The bottom surface of the pressing limiting block 103 is provided with a protective anti-skid rubber pad to protect the surface of the workpiece and increase the friction. When the workpiece is rotated by the placing disc 2, the pressing limiting block 103 will rotate independently relative to the L-shaped connecting rod 102 with the workpiece and the placing disc 2. After the centering work is completed, the L-shaped connecting rod 102 can be rotated to move it away from above the placing disc 2 to avoid blocking.

[0029] Further, the dust removal mechanism includes a fan 105 fixedly installed on the upper surface of the measuring table 1. One end of the connecting pipe 106 connected in communication with the air outlet end of the fan 105 is installed in communication with the other end of the connecting pipe 106.

[0030] The fan 105 is fixedly installed on the upper surface of the measuring table 1 and generates airflow during operation. The airflow is delivered to the air outlet cover 107 through the connecting pipe 106, and the air outlet cover 107 uniformly disperses the airflow above the measuring area to form an air curtain, which carries away the dust away from the measuring table 1, the placing disc 2 and the surface of the workpiece.

[0031] Further, the bottom surface of the placing disc 2 is fixedly installed with a position sensor, which is electrically connected with the control display module 6.

[0032] The position sensor installed on the bottom surface of the placing disc 2 captures the position information of the placing disc 2 in real time, such as the lifting height and the rotation angle, and transmits it to the control display module 6 in the form of an electrical signal. The module 6 analyzes and processes the data, and in combination with the ranging information of the plurality of laser sensors 5, the accuracy of the center coordinate determination can be improved.

[0033] Working principle: first, the workpiece is placed on the placement disc 2 in the round groove 101 of the measuring table 1, the motor 304 in the equipment box 3 is started, the gear 303 is driven to rotate, the gear ring 301 is engaged to rotate around the outer wall of the cylindrical structure protruding part, the placement disc 2 is driven to rotate through the telescopic connecting rod 302, and a plurality of annular uniformly distributed laser sensors 5 continuously detect the distance of the workpiece on the placement disc 2, scan the outer wall contour size, calculate the workpiece center position in combination with the control display module 6 and transmit it to the four-face milling equipment; if the outer wall is irregular, the second cylinder 305 in the measuring table 1 can be telescopic, cooperates with the rotating lifting structure to accurately change the height of the placement disc 2, so that the laser sensor 5 measures the distance of the outer wall of different heights, and improves the accuracy of the center coordinate finding; during the measurement process, the first cylinder 104 drives the L-shaped connecting rod 102, and the pressing limiting block 103 is pressed to press the workpiece, the bottom protection anti-skid rubber pad can protect the workpiece and increase the friction force, and the pressing limiting block 103 can also rotate relatively independently when the placement disc 2 rotates, and can be removed after the division is completed to avoid shielding; after one-time division milling is completed, the fan 105 generates airflow through the connecting pipe 106 to the air outlet cover 107, forms a wind curtain to carry away dust away from the measuring table 1, the placement disc 2 and the workpiece surface; in addition, the position sensor at the bottom of the placement disc 2 captures position information in real time and transmits it to the control display module 6, in combination with the distance measuring information of the laser sensor 5, the accuracy of the center coordinate determination is further improved.

[0034] It should be noted that the specific type and size of the first cylinder 104, the fan 105, the motor 304, the second cylinder 305, the laser sensor 5, the control display module 6 and the position sensor need to be selected and determined according to the actual size of the device, and the specific selection calculation method adopts the existing technology in the art, so it will not be described in detail.

[0035] The power supply and principle of the first cylinder 104, the fan 105, the motor 304, the second cylinder 305, the laser sensor 5, the control display module 6 and the position sensor are clear to those skilled in the art, and will not be described in detail here.

For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
