Description

Technical Field

[0001] The present invention relates to the technical field of inclined surface detection, and in particular to an auxiliary device and a detection method for inclined surface space dimension detection. Background Art

[0002] In modern manufacturing, many workpieces have bevels or chamfers on their surfaces. These structures are widely used in mechanical processing, mold manufacturing and assembly processes. Traditional detection methods usually have certain limitations for the precise measurement of bevel dimensions, especially the measurement of the spatial dimensions of bevels with rounded corners. For workpieces with bevels and rounded corners, conventional methods use auxiliary templates combined with calipers for measurement, or use indirect conversion methods. The method of using auxiliary templates combined with calipers for measurement requires the preparation of auxiliary templates with angles consistent with the inclination angle of the bevel. When measuring workpieces of different specifications, the auxiliary templates need to be customized again, which is not very versatile. When using the indirect conversion method, the bevel angle deviation is not considered, resulting in large measurement errors, and calculations need to be performed every time the side face is measured, which is inefficient.

[0009] One end of the connecting rod 2 is connected to the double-sided crank via a third pin shaft, and the other end is fixedly connected to the measuring block via a fourth pin shaft;

[0010] When the inclined surface positioning base rotates around the plane positioning base, the articulated connecting rod assembly drives the double-sided cranks to rotate through the transmission of connecting rod 1, and then drives connecting rod 2 to drive the measuring block to slide in a straight line, so that the measuring surface of the measuring block is always kept on a unified vertical line with the intersection of the inclined surface and the plane.

[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0035] The following is combined with Figure 1-3 This application is described in further detail.

[0036] The present application discloses an auxiliary device and method for detecting the size of a slope space.

[0037] Reference Figure 1 The inclined plane spatial dimension detection auxiliary device includes two measuring components, which include a plane positioning base 1, an inclined plane positioning base 13, an articulated connecting rod group 14 and a measuring block 15. The plane positioning base 1 is used to fit the plane of the workpiece, the inclined plane positioning base 13 is used to fit the inclined plane of the workpiece, and a measuring surface is formed at the end of the measuring block 15. The inclined plane positioning base 13 is hinged to the plane positioning base 1 through a first pin shaft, so that the inclined plane positioning base 13 can rotate freely around the center of the first pin shaft; one end of the articulated connecting rod group 14 is fixedly connected to the inclined plane positioning base 13, and the other end is connected to the measuring block 15, which is used to drive the measuring block 15 to slide along the axial direction of the plane positioning base 1 through the rotation of the inclined plane positioning base 13, and the movement amount of the measuring block 15 is consistent with the change of the intersection point of the inclined plane and the plane.

[0038] The plane positioning base 1 is used to contact the plane of the workpiece and provide a stable measurement reference; the inclined plane positioning base 13 is used to contact the inclined plane of the workpiece. It is hinged to the plane positioning base 1 through the first pin, so that the inclined plane positioning base 13 can rotate freely around the pin to adapt to the measurement of inclined planes at different angles. One end of the hinged connecting rod group 14 is fixedly connected to the inclined plane positioning base 13, and the other end is connected to the measuring block 15. The rotation of the inclined plane positioning base 13 drives the measuring block 15 to slide along the axial direction of the plane positioning base 1, ensuring that the sliding amount of the measuring block 15 is consistent with the change of the intersection of the inclined plane and the plane, ensuring that the measuring surface is always on a unified vertical line with the intersection, thereby achieving accurate spatial dimension measurement. The lower plane of the plane positioning base 1 is the measurement reference plane, which is close to the surface of the workpiece during measurement. A hinged seat is provided on the left side to connect the inclined plane positioning base 13, and a mounting groove and a corresponding positioning pin hole are provided on the right side. The upper part is the mounting groove and positioning pin of the gauge block fixing seat 12, and a clearance groove is provided in the middle according to the movement space of the connecting rod assembly; a hinged seat is provided at the top of the inclined plane positioning base 13, which is connected to the left side of the plane positioning base 1 through a pin shaft so that the inclined plane positioning base 13 can rotate freely around the center of the pin shaft, and zero degrees is the vertical state of the inclined plane positioning reference plane and the plane positioning base 1, at which time the measuring surface of the measuring block 15 coincides with the inclined plane positioning reference plane;

[0039] Reference Figure 2 The articulated connecting rod group 14 includes a connecting rod 141, a double-sided crank 142 and a connecting rod 2 143; one end of the connecting rod 141 is fixedly connected to the extended connecting rod of the inclined surface positioning base 13, and the other end is hinged to one end of the double-sided crank 142 through a first pin; the middle part of the double-sided crank 142 is hinged to the center position of the gauge block fixing seat 12 through a second pin, and can rotate around the pin, and the other end of the double-sided crank 142 is hinged to one end of the connecting rod 2 143 through a third pin. Hinged; one end of the second connecting rod 143 is connected to the double-sided crank 142 through the third pin, and the other end is fixedly connected to the measuring block 15 through the fourth pin; when the inclined surface positioning base 13 rotates around the plane positioning base 1, the hinged connecting rod group 14 drives the double-sided crank 142 to rotate through the transmission of the first connecting rod 141, and then drives the second connecting rod 143 to drive the measuring block 15 to slide in a straight line, so that the measuring surface of the measuring block 15 is always kept on a unified vertical line with the intersection of the inclined surface and the plane.

[0040] Specifically, a fixed connecting rod extends from the middle of the inclined plane positioning base 13, and the connecting rod rotates with the inclined plane positioning reference, which is equivalent to the prime mover of the hinged connecting rod group 14. The hinged connecting rod group 14 consists of a connecting rod 141, a double-sided crank 142, and a connecting rod 2 143. The connecting rods are connected by pins and can rotate freely with each other. The connecting rod 141 is connected to the connecting rod on the inclined plane positioning base 13, and the middle of the double-sided crank 142 is hinged in the middle of the gauge block fixing seat 12 so that it can only rotate around the hinge point. The end of the connecting rod group is connected to the measuring block 15, and the movement of the connecting rod group is driven by the rotation of the inclined plane positioning reference plane, and finally the measuring block 15 is pushed to slide left and right in the gauge block fixing seat 12, and the movement amount Δ is always equal to the movement value Δ' of the intersection of the two planes after the inclined plane positioning base 13 rotates around the plane positioning base 1 by an angle θ, thereby ensuring that the intersection is always on a vertical line with the measuring surface of the measuring block 15.

[0041] In one embodiment, the articulated connecting rod group 14 can be replaced by a worm gear mechanism, a rack and pinion mechanism, a cylinder drive system or an electric servo drive system. The worm gear mechanism transmits rotational motion by meshing the worm and the worm wheel. The advantage is that it can achieve large torque transmission in a small space and has a good deceleration effect. It is suitable for applications that accurately control the angle. The rack and pinion mechanism can convert rotational motion into linear motion, and has high transmission efficiency and precision. The advantages are high transmission precision, durability and providing large transmission force. It is suitable for occasions that require high precision and fast response. The cylinder drive system drives the piston movement through gas pressure. The advantages are fast response speed, high power and stable operation. It is suitable for applications that require fast adjustment or strong drive, but usually requires an external gas source. The electric servo drive system uses motors and servo control to accurately adjust the position. The advantages are high precision and strong adjustability. It is suitable for automation and complex motion control. When choosing an alternative, you need to make a decision based on the application scenario and measurement accuracy, force and control requirements.

[0042] A gauge block holder 12 is fixedly connected to the plane positioning base 1, and a measuring block 15 is slidably connected to the gauge block holder 12. A locking screw for locking the gauge block is threadedly connected to the gauge block holder 12. When the inclined surface positioning base 13 is adjusted to contact the inclined surface of the workpiece and adjusted to the desired angle by rotation, the measuring block 15 will slide axially in the gauge block holder 12 so as to be consistent with the intersection of the inclined surface and the plane of the workpiece. When the intersection of the measuring block 15 and the workpiece is aligned, the locking screw needs to be used to lock the gauge block. The locking gauge block is fixed in the gauge block holder 12 by a locking screw connected by a thread, so as to prevent the measuring block 15 from being displaced during the subsequent measurement process, thereby ensuring the stability and accuracy of the measurement result. The gauge block is locked only when the position of the measuring block 15 is accurate, so as to ensure that the measuring block 15 will not change position due to vibration or external force during the measurement process.

[0043] Magnetic blocks are arranged on the side of the plane positioning base 1 and the inclined surface positioning base 13 that are in contact with the workpiece. The purpose of arranging magnetic blocks on the side of the plane positioning base 1 and the inclined surface positioning base 13 that are in contact with the workpiece is to enhance the stability and fixity between the device and the workpiece. The magnetic blocks can generate suction so that the base is firmly adsorbed on the surface of the workpiece to prevent the base from moving due to external force or vibration during the measurement process, thereby ensuring the accuracy of the measurement. In the specific setting, the magnetic blocks are usually arranged on the contact surface of the base, and the positions are evenly distributed to ensure that sufficient suction can be provided to firmly fix the base so that it fits tightly with the plane and inclined surface of the workpiece. The surface of the magnetic block is usually designed to be lower than the contact surface of the base to avoid interference and ensure stable contact, while preventing gaps or uneven contact between the base and the surface of the workpiece, further improving the accuracy of the measurement.

[0044] A T-shaped mounting groove is provided on the plane positioning base 1, and the bottom of the gauge block fixing seat 12 is inserted into the mounting groove and fixed by a positioning pin. The T-shaped mounting groove provided on the plane positioning base 1 provides a precise insertion position for the gauge block fixing seat 12, ensuring that the gauge block fixing seat 12 can be firmly installed on the plane positioning base 1. After the bottom of the gauge block fixing seat 12 is inserted into the T-shaped mounting groove, it is fixed by a positioning pin to ensure that the gauge block fixing seat 12 will not be displaced after installation, and maintain its position stability relative to the plane positioning base 1. This structural design allows the gauge block fixing seat 12 to accurately maintain its position during the measurement process, thereby ensuring that the measuring block 15 is always in precise contact with the plane and inclined surface of the workpiece, ensuring the accuracy of the measurement.

[0045] The inclined plane spatial dimension detection auxiliary device also includes a telescopic measuring crossbar 2, the two ends of the telescopic measuring crossbar 2 are respectively connected to a measuring component, and the telescopic measuring crossbar 2 is provided with a linear scale for directly reading the spacing between the two measuring components. The telescopic measuring crossbar 2 is connected to the two ends of the two measuring components, allowing telescopic adjustment according to the width requirements of the workpiece to be measured, so as to adapt to workpieces of different sizes. The linear scale provided on the crossbar is used to directly read the distance between the two measuring components and provide accurate spatial dimension data. When in use, the telescopic measuring crossbar 2 can adjust the length as needed to ensure that the spacing between the two measuring components is consistent with the actual size of the workpiece to be measured, so that during the measurement process, the user can easily read and record the accurate spacing data, and then determine the spatial size of the workpiece.

[0046] The telescopic measuring cross bar 2 includes a left scale box 21, a right scale box 21 and a main measuring scale 22, and a linear scale is set on the main measuring scale 22; positioning stops are provided at both ends of the left scale box 21 and the right scale box 21, which are respectively inserted into the mounting grooves of the plane positioning base 1 and fixed by positioning pins, and guide grooves are provided inside the left scale box 21 and the right scale box 21; sliding grooves are provided on both sides of the main measuring scale 22, corresponding to the guide grooves of the left scale box 21 and the right scale box 21, and the main measuring scale 22 can slide along the guide grooves to realize telescopic adjustment.

[0047] The main measuring ruler 22 is also provided with an angle value scale, and the angle value scale value is generated by converting the extended length of the measuring block 15 with the rotation angle of the inclined plane positioning reference. Positioning stoppers are provided at both ends of the left ruler box 21 and the right ruler box 21, which are used to insert them into the installation groove of the plane positioning base 1 and fix them by positioning pins to ensure the stability of the entire measuring system. Guide grooves are provided inside the left ruler box 21 and the right ruler box 21 to provide guidance for the sliding of the main measuring ruler 22. A linear scale is provided on the main measuring ruler 22 for directly reading the measurement data. Slide grooves are provided on both sides of the main measuring ruler 22, which cooperate with the guide grooves of the left ruler box 21 and the right ruler box 21, so that the main measuring ruler 22 can slide in the guide groove, thereby realizing telescopic adjustment to adapt to workpieces of different sizes. When in use, by adjusting the position of the main measuring ruler 22, the length of the telescopic measuring crossbar 2 can be flexibly adjusted to adapt to the measurement of workpieces of different widths, and the distance between the two measuring components can be accurately read through the scale on the main measuring ruler 22.

[0048] The left scale box 21 and the right scale box 21 are respectively provided with set screws, and the main measuring scale 22 is provided with a slide groove that cooperates with the set screws, which is used to lock the position of the main measuring scale 22 after it is adjusted into place. The set screws provided on the left scale box 21 and the right scale box 21 are used to lock the position of the scale box 21 by tightening the screws after the main measuring scale 22 is adjusted to the desired position, so as to prevent it from moving during the measurement process. The slide groove provided on the main measuring scale 22 is used in conjunction with the set screws. After the set screws are inserted into the slide groove, it is ensured that the main measuring scale 22 can be accurately positioned and fixed during the sliding adjustment process to prevent position changes due to loosening or vibration, thereby ensuring the stability and accuracy of the measurement results. During use, after the main measuring scale 22 is adjusted to the desired position, it is locked by the set screw to ensure that the position does not change during the measurement process, and the measurement data can be accurately read.

[0049] Reference Figure 3 According to another aspect of the present invention, a method for detecting the spatial dimension of an inclined surface is provided, which comprises the following steps: S100, installing two measuring components at the two ends of the surface to be measured of the workpiece respectively.

[0050] The specific operation of this step is to place and fix the two measuring components at the two ends of the workpiece respectively to ensure the measurement accuracy. First, fit the plane positioning base 1 on a plane of the workpiece to ensure that it is stable and aligned with the plane of the workpiece. Then, adjust the bevel positioning base 13 so that it contacts the bevel of the workpiece and rotates to an appropriate angle to ensure that the bevel positioning base 13 fits tightly with the bevel of the workpiece. The design of the two measuring components allows them to be installed at both ends of the workpiece respectively to ensure that their positions are consistent with the intersection of the bevel of the workpiece and the surface to be measured. In this way, the measuring block 15 can accurately align the intersection of the bevel and the plane of the workpiece to ensure that subsequent measurement operations are accurate and correct.

[0051] S200, place the reference surface of the plane positioning base 1 close to a plane of the workpiece to be measured, adjust the inclined surface positioning base 13, and rotate the inclined surface positioning base 13 according to the angle of the inclined surface of the workpiece to make it completely fit the inclined surface of the workpiece. The inclined surface positioning base 13 drives the measuring block 15 to slide through the hinged connecting rod group 14, so that the measuring surface of the measuring block 15 is consistent with the intersection of the inclined surface and the plane of the workpiece.

[0052] First, place the reference surface of the plane positioning base 1 close to the plane of the workpiece, ensure that there is no gap between the base and the plane of the workpiece and firmly fix it to ensure the stability of the measurement. Then, adjust the angle of the bevel positioning base 13 so that it completely fits the bevel of the workpiece. This is achieved by rotating the bevel positioning base 13, and the angle of rotation is adjusted according to the angle of the bevel of the workpiece. The bevel positioning base 13 is hinged to the plane positioning base 1 through the first pin, so that the bevel positioning base 13 can rotate freely. Next, the rotation of the bevel positioning base 13 is transmitted to the measuring block 15 through the articulated connecting rod group 14, and the movement of the articulated connecting rod group 14 drives the measuring block 15 to slide along the axial direction of the plane positioning base 1, ensuring that the measuring surface of the measuring block 15 is always consistent with the intersection of the bevel and the plane of the workpiece, thereby achieving accurate spatial dimension measurement.

[0053] S300, when the measuring surface heights on both sides of the workpiece are consistent and there is no obstacle interference, the telescopic measuring cross bar 2 can directly connect the two measuring components, and the spatial dimensions and bevel angles of the intersection of the inclined surfaces of the workpiece to be measured can be read through the scale on the telescopic measuring cross bar 2; when the measuring heights on both sides of the workpiece are not the same, or there is an obstacle interference, remove the telescopic measuring cross bar 2, and use a caliper to measure the distance between the measuring blocks 15 on the two measuring components to obtain the spatial dimensions of the intersection of the inclined surfaces of the workpiece to be measured.

[0054] If the heights of the measuring surfaces on both sides are consistent and there is no obstacle in the middle, choose to use the telescopic measuring crossbar 2, insert the two ends of the telescopic measuring crossbar 2 into the installation slot of the measuring component, ensure that the positioning stop is accurately inserted and fixed with the positioning pin, slide the main measuring ruler 22 along the guide groove to an appropriate length, so that the crossbar connects the two measuring components, read the linear scale on the main measuring ruler 22, and directly obtain the distance between the two measuring components as the spatial dimension of the intersection of the workpiece bevel, and read the angle value of the workpiece bevel through the angle scale on the crossbar. If it is found that the heights of the measuring surfaces on both sides of the workpiece are inconsistent or there is an obstacle in the middle, remove the telescopic measuring crossbar 2 and use a caliper to replace it for measurement, ensure that the measuring points at both ends of the caliper are respectively located on the measuring blocks 15 of the two measuring components, read the measured value displayed by the caliper as the distance between the two measuring blocks 15, and record the data as the spatial dimension of the intersection of the workpiece bevel. If the bevel angle value is required, the bevel angle can be calculated according to the corresponding conversion formula of the extended length of the measuring block 15 and the rotation angle of the bevel positioning base 13. After the measurement is completed, record the measured spatial dimensions and angle data for subsequent analysis or process adjustment.
