Description

Technical Field

[0001] The present application relates to the field of mechanical technology, and in particular to a cylinder depth measuring device. Background Art

[0002] Traditionally, the measurement of cylinders (i.e., cylindrical shells) is usually done manually, i.e., at the assembly station, using a large depth gauge to measure in a conventional way. However, manual measurement will increase labor costs, low measurement efficiency, and measurement errors due to over-reliance on manual labor.

[0003] Therefore, some companies will use a cantilever measuring mechanism to measure the cylinder. However, the inventors found that the current cantilever measuring mechanism requires the end face of the cylinder to be perpendicular to the measuring platform of the measuring mechanism, which leads to a long leveling time for the measuring mechanism and a long placement and adjustment time for the cylinder, resulting in low measurement efficiency of the cylinder.

The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0102] See also Figure 1-Figure 5, the embodiment of the present application provides a barrel depth measuring device, comprising: a measuring mechanism 1, a moving mechanism 2, a mounting base 3, a floating mechanism 4 and a measuring reference seat 5;

[0103] The measuring mechanism 1 is used to measure the depth of the cylinder;

[0104] The measuring mechanism 1 is connected to the moving mechanism 2, and the moving mechanism 2 is used to control the measuring mechanism 1 to move along the depth direction of the cylinder, so that the measuring mechanism 1 measures the depth of the cylinder;

[0105] The mobile mechanism 2 is connected to the mounting base 3, and the mounting base 3 is used to support the mobile mechanism 2 and the measuring mechanism 1;

[0106] The mounting base 3 is detachably connected to the floating mechanism 4, and the floating mechanism 4 is also connected to the horizontal slide mechanism; wherein the floating mechanism 4 is used to connect or disconnect the mounting base 3 from the horizontal slide mechanism; when the floating mechanism 4 connects the mounting base 3 to the horizontal slide mechanism, the horizontal slide mechanism is used to control the mounting base 3, the measuring mechanism 1 and the moving mechanism 2 to move in the horizontal direction through the floating mechanism 4;

[0107] The measuring mechanism 1 is also connected to a lifting mechanism, which is used to control the cylinder depth measuring device to move in the vertical direction;

[0108] The measuring reference seat 5 is connected to the bottom of the mounting base 3, and the bottom of the measuring reference seat 5 is used to contact the end face of the cylinder; when the floating mechanism 4 causes the mounting base 3 to be separated from the horizontal slide mechanism, the bottom of the measuring reference seat 5 will fit the end face of the cylinder and make the moving direction of the measuring mechanism 1 parallel to the axis of the cylinder.

[0109] The working principle of the above technical solution is: the cylinder depth measuring device is moved to the top of the cylinder by the horizontal slide mechanism, and the floating mechanism 4 is used to connect or disconnect the mounting base 3 with the horizontal slide mechanism;

[0110] When the floating mechanism 4 connects the mounting base 3 with the horizontal slide mechanism, the horizontal slide mechanism is used to control the mounting base 3, the measuring mechanism 1 and the moving mechanism 2 to move in the horizontal direction through the floating mechanism 4;

[0111] Control the lifting mechanism to move the cylinder depth measuring device downward, so that the floating mechanism 4 disengages the mounting base 3 from the horizontal slide mechanism, and the bottom of the measuring reference seat 5 will fit the end face of the cylinder. At this time, the moving direction of the measuring mechanism 1 is parallel to the axis of the cylinder.

[0112] The positional relationship between the measuring mechanism 1 and the cylinder is adjusted by moving the mechanism 2, and the measuring mechanism 1 is controlled to measure the depth of the cylinder. Under the premise of ensuring the accuracy of the depth measurement, the leveling of the measuring mechanism 1 and the adjustment of the placement of the cylinder are avoided, which greatly reduces the time consumed in measuring the depth of the cylinder and improves the measurement efficiency.

[0113] Preferably, the measuring mechanism 1 comprises: a measuring rod 11 and a measuring frame 12;

[0114] One end of the measuring rod 11 passes through the mounting base 3, and the end of the measuring rod 11 passing through the mounting base 3 is used to measure the depth of the cylinder;

[0115] The measuring rod 11 is slidably connected to the measuring frame 12. The measuring frame 12 is used to limit the movement of the measuring rod 11 along a first direction. The first direction is consistent with the depth direction of the cylinder.

[0116] Therefore, the measuring rod 11 is arranged on the moving mechanism 2 via the measuring frame 12 .

[0117] Furthermore, the measuring rod 11 includes: a rod body 111, a measuring head 112, a grating ruler 113 and a slider 114;

[0118] The rod body 111 is used to be inserted into the cylinder along a first direction;

[0119] One end of the rod body 111 is connected to a probe 112, and the probe 112 is used to contact the bottom end of the cylinder;

[0120] The side surface of the rod body 111 is connected to the grating ruler 113, and the slider 114 is movably connected to the grating ruler 113;

[0121] The slider 114 is connected to the measuring frame 12 via the linkage pin 116. The slider 114 is used to mark the scale on the grating ruler 113. The scale is used to indicate the depth of the rod body 111 inserted into the cylinder when the rod body 111 drives the grating ruler 113 to be inserted into the cylinder.

[0122] Exemplarily, the lifting mechanism is controlled to move the cylinder depth measuring device downward by a length a, so that the floating mechanism 4 causes the mounting base 3 to be separated from the horizontal slide mechanism.

[0123] When the bottom of the measuring reference seat 5 is about to fit the end surface of the cylinder, the scale indicated by the slider 114 on the grating ruler 113 is h1.

[0124] When the measuring mechanism 1 is controlled to measure the depth of the cylinder, the measuring rod 11 and the measuring head 112 are inserted into the cylinder, and the measuring head 112 contacts the bottom of the cylinder, the scale indicated by the slider 114 on the grating ruler 113 is h2. At this time, the measured depth of the cylinder b = h2-h1.

[0125] Furthermore, the measuring rod 11 further includes: a Z-axis slide rail 115; the interior of the measuring frame 12 has a slide groove 123 arranged along the first direction;

[0126] The Z-axis slide rail 115 is connected to the side of the rod body 111, and the axis of the Z-axis slide rail 115 is parallel to the axis of the rod body 111;

[0127] The Z-axis slide rail 115 is slidably connected to the slide groove 123 , and the slide groove 123 limits the movement of the rod body 111 along the first direction through the Z-axis slide rail 115 .

[0128] Further, the measuring head 112 includes: a measuring head 1121, a spring 1122 and a displacement sensor 1123;

[0129] The measuring head 1121 is used to contact the bottom end of the cylinder;

[0130] One end of the measuring head 1121 away from the bottom end of the cylinder is connected to a spring 1122, and the spring 1122 is used to absorb the impact force when the measuring head 1121 contacts the bottom end of the cylinder;

[0131] One end of the spring 1122 away from the measuring head 1121 is connected to a displacement sensor 1123, wherein the displacement sensor 1123 is used to determine the reverse distance that the measuring head 1121 moves in the direction opposite to the moving direction of the rod body 111 after contacting the bottom end of the cylinder;

[0132] The displacement sensor 1123 is also used to generate an in-position signal, wherein the in-position signal is a signal generated when the reverse distance reaches a preset distance threshold, and the in-position signal is used to indicate that the measuring head 1121 has contacted the bottom end of the cylinder.

[0133] For example, when the measuring head 1121 contacts the bottom of the cylinder, it will move in the first direction in the opposite direction by a first distance. If the first distance reaches a distance threshold (e.g., 5 mm), it means that the measuring head 1121 has reached the bottom of the cylinder, and the displacement sensor 1123 will generate an in-position signal, which is used to control the moving device to stop the measuring rod 11 and the measuring head 112 from moving. At this time, the scale indicated by the slider 114 on the grating ruler 113 will represent the depth of the cylinder. At this time, the measured depth of the cylinder b = h2-h1+distance threshold.

[0134] Preferably, the measuring frame 12 comprises: a supporting plate 121 and a connecting plate 122;

[0143] Therefore, the measurement mechanism 1 is moved in three dimensions by the first moving mechanism 21 and the second moving mechanism 22, so that the measurement position at the bottom of the cylinder can be adjusted, thereby enabling adjustment of multiple measurement points at the bottom of the cylinder, and obtaining the depth of each measurement point. The average of the depths of the measurement points is calculated as the final depth of the cylinder, so as to improve the measurement accuracy of the cylinder depth.
