[0001] The invention relates to the technical field of shaft system workpiece machine tool positioning and docking, and in particular to an ultra-large shaft system flange hole assembly machine tool. Background Art

[0002] Super-large shaft flange holes refer to hole structures set on shaft workpieces for assembly and fixation. These holes are mainly used to pass bolts or shaft pins and cooperate with flanges to achieve connection and fixation between shafts.

[0003] In the process of positioning and docking super-large shaft workpieces with the help of machine tools, due to the large mass of the workpiece itself, the position and angle between them need to be constantly adjusted during assembly to ensure the assembly accuracy between the shafts, which is extremely difficult during the operation. At the same time, during the processing of the super-large shaft workpiece, the clamping and processing procedures of the workpiece are difficult, and it is difficult to ensure the processing accuracy of the super-large shaft. The heat generated during the processing may cause local or overall thermal expansion of the shaft material, and uneven shrinkage after cooling, which can easily cause dimensional deviations, resulting in deviations in the diameters of both ends of the processed shaft, making it a non-standard part, which is difficult to distinguish when the super-large shafts are docked, resulting in unstable docking points when the super-large shafts are docked, or even failure to dock, thereby affecting the quality and efficiency of the docking.

DETAILED DESCRIPTION

[0035] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Embodiment 1: A super large shaft flange hole assembly machine tool, such as Figure 1-Figure 6 As shown, it includes a machine tool 101, the top of the machine tool 101 is slidably connected to a machine base 1021 in the left-right direction, the machine base 1021 is slidably connected to a sliding frame 102 symmetrically distributed along the front and back of the machine base 1021, and there are four sliding frames 102. The machine base 1021 is rotatably connected to screws 103 symmetrically distributed along the left and right of the machine base 1021, and the sliding frame 102 is threadedly connected to the adjacent screws 103. The top of the sliding frame 102 is rotatably connected to a first carrier frame 104, and the middle of the top of the machine base 1021 is slidably connected to The second carrier 106 has a balance bar 108 rotatably connected to the middle of the top of the second carrier 106. The top surface of the balance bar 108 in contact with the workpiece is set as a concave surface. A second spring 109 symmetrically distributed along the balance bar 108 is fixedly connected between the balance bar 108 and the second carrier 106. A measuring table 110 is fixedly connected to the front side of the upper part of the second carrier 106. A measuring rod 111 is fixedly connected to the front side of the balance bar 108. The measuring rod 111 is rotatably connected to the measuring table 110. The top of the machine tool 101 A hydraulic cylinder 112 is fixedly connected in the middle of the hydraulic cylinder 112, and the piston rod of the hydraulic cylinder 112 is fixedly connected to the machine base 1021. A converter 113 is fixedly connected to the left front side of the hydraulic cylinder 112. A liquid inlet groove 114 is opened on the upper side of the converter 113, and a reflux groove is opened on the lower side of the converter 113. The reflux groove of the converter 113 is connected to the external oil tank. A conversion column 115 is slidably connected in the converter 113 along the up and down directions. A through groove is opened at the lower part of the conversion column 115. The through groove of the conversion column 115 is connected to the liquid inlet groove 114. When the conversion column 115 is opened, the conversion column 115 is opened. The through groove is connected to the liquid inlet groove 114. When the column 115 moves downward, the liquid inlet groove 114 and the reflux groove of the converter 113 are connected to the through groove of the conversion column 115, the upper side of the converter 113 is connected with a hose 116, the top front side of the second carrier 106 is fixedly connected with a cylinder structure 117, the hose 116 is connected with the cylinder of the cylinder structure 117, a cam 118 is fixedly connected to the measuring rod 111, the cam 118 is squeezed and matched with the piston rod of the cylinder structure 117, and a return spring 119 is fixedly connected between the piston rod of the cylinder structure 117 and the cylinder.

[0037] Firstly, before using this machine tool to assemble the shaft workpiece, first adjust the distance between adjacent sliding frames 102 by screw 103 according to the thickness of the shaft workpiece, so as to adjust the distance between adjacent first carriers 104, so that the shaft workpiece can be placed between the four first carriers 104 without falling, and use measuring tools to ensure that the distance between the left sliding frames 102 is the same as the distance between the right sliding frames 102. After adjustment, place the shaft workpiece between the four first carriers 104. Under the action of the gravity of the shaft workpiece, the first carrier 104 will rotate to a corresponding angle to adapt to and embrace the shaft workpiece of corresponding thickness. In this way, through the simple design of the first carrier 104, shaft workpieces of different thicknesses can be quickly positioned.

[0038] Secondly, since it is an ultra-large shaft workpiece, it is difficult to clamp and process the ultra-large shaft workpiece, and the processing accuracy is difficult to ensure. It is easy to produce processing errors, making the shaft workpiece a non-standard part with unequal diameters at both ends. Therefore, it cannot be guaranteed that all shaft workpieces can be placed between the first carriers 104 in a balanced manner before assembly. It is necessary to abandon the non-standard shaft workpiece before assembly, which is specifically judged in the following way:

[0039] After the shafting workpiece is placed on the first carrier 104, the second carrier 106 is pushed upward, and the second carrier 106 pushes the balance bar 108 upward to contact the bottom of the shafting workpiece through the second spring 109. If the shafting workpiece is a standard part, the bottom surfaces on both sides of the shafting workpiece are in contact with the top concave surface of the balance bar 108 at the same time, and the balance bar 108 is balanced and compressed without swinging, so that the measuring rod 111 does not swing. By observing that the measuring rod 111 stays in the middle position of the measuring table 110, it is determined that the shafting workpiece is a standard part.

[0040] When the measuring rod 111 does not swing, the hydraulic cylinder 112 is started, and all the hydraulic oil flowing into the external oil tank through the liquid inlet groove 114 will pass through the through groove of the conversion column 115 and flow into the hydraulic cylinder 112. When the hydraulic oil supply is sufficient, the hydraulic cylinder 112 will push the machine base 1021 to slide along the machine tool 101, so that the shaft system workpiece of the standard part can be docked.

[0041] If the shafting workpiece is a non-standard part, the bottom surface of the relatively thicker side of the outer surface of the shafting workpiece will first contact the top concave surface of the balance bar 108, causing the balance bar 108 to be unbalanced under pressure, and then causing the compressed side of the balance bar 108 to swing downward, and the second spring 109 on this side is compressed, and the pressure-depleted side of the balance bar 108 swings upward, and the second spring 109 on this side is stretched. The swing of the balance bar 108 drives the measuring rod 111 to swing left or right in the measuring table 110, and the shafting workpiece is determined to be a non-standard part by observing the deviation of the measuring rod 111 from the middle position.

[0042] When the measuring rod 111 swings to the left or right in the measuring table 110, the measuring rod 111 drives the cam 118 to swing to the left or right. The swinging of the cam 118 in any direction will squeeze the piston rod of the cylinder structure 117 to slide into the cylinder, and the return spring 119 is compressed, so that the gas in the cylinder structure 117 enters the converter 113 through the hose 116. Under the action of air pressure, the conversion column 115 moves downward, so that the through groove of the conversion column 115 is connected between the liquid inlet groove 114 and the reflux groove of the converter 113. At this time, part of the hydraulic oil flowing into the external oil tank through the liquid inlet groove 114 will leak into the reflux groove of the converter 113 through the through groove of the conversion column 115, and then flow back to the external oil tank through the reflux groove. Due to insufficient supply of hydraulic oil, the hydraulic cylinder 112 cannot be started, which makes it impossible to push the machine base 1021 to slide along the machine tool 101, and thus makes it impossible to dock the shaft workpiece of the non-standard parts.

[0043] In this way, the shaft system workpieces judged as non-standard parts are removed and the assembly is stopped, leaving the shaft system workpieces judged as standard parts, and continuing the subsequent processing and assembly. Specifically: two standard shaft system workpieces are respectively positioned in a balanced manner on two such assembly devices in the above-mentioned manner, and first, circularly distributed flange holes are processed on one side of the two shaft system workpieces by special tools (during processing, the shaft system workpieces can be rotated on this device. Since the shaft system workpieces are balanced and positioned before processing, the misalignment of the flange holes can be avoided), and then the two shaft system workpieces are assembled together by matching flanges and fastening bolts (since the two docking shaft system workpieces are placed in a balanced manner, they are easier to align during assembly).

[0044] like Figure 1 and Figure 7 As shown, it also includes a rotating frame 201, which is rotatably connected to the upper rear side of the base 1021, and the base 1021 is fixedly connected to a motor 202 that is symmetrically distributed along the left and right sides of the base 1021, and the output shaft of the motor 202 is fixedly connected to the rotating frame 201, and the rotating frame 201 is rotatably connected to a first roller 203 that is symmetrically distributed along the left and right sides of the rotating frame 201.

[0045] After placing the standard shaft workpiece between the four first carrier frames 104, start the motor 202 first. The output shaft of the motor 202 drives the rotating frame 201 to swing forward. The rotating frame 201 drives the first roller 203 to swing forward until it contacts the top end surface of the shaft workpiece, further limiting the shaft workpiece, so that the shaft workpiece is more stable during the subsequent assembly process.

[0046] like Figure 1 , Figure 8 and Fig. 9As shown, it also includes a connecting rod 301 symmetrically distributed along the rotating frame 201, the connecting rod 301 is fixedly connected to the rotating frame 201, the machine base 1021 is fixedly connected with fixed guide blocks 302 symmetrically distributed along the left and right of the machine base 1021, and a second sliding plate 303 is horizontally slidably connected between adjacent fixed guide blocks 302, the second supporting frame 106 is slidably connected to the first sliding plate 105 at the bottom, the first sliding plate 105 is fixedly connected with fixed rods 304 symmetrically distributed along the left and right of the first sliding plate 105, the second sliding plate 303 pushes and pulls the first sliding plate 105 to move through the fixed rods 304, the second sliding plate 303 is limited by the adjacent fixed rods 304 through the inclined groove, and the first sliding plate 105 and the second supporting frame 106 are fixedly connected with first springs symmetrically distributed along the first sliding plate 105.

[0047] The rotating frame 201 rotates while driving the connecting rod 301 to rotate. When the rotating frame 201 rotates forward and downward, the rotating frame 201 pulls the second sliding plate 303 to slide backward along the fixed guide block 302 through the connecting rod 301. The second sliding plate 303 squeezes the fixed rod 304 to move upward through the inclined groove, thereby driving the first sliding plate 105 to move upward. The first sliding plate 105 drives the second supporting frame 106 to move upward through the first spring 107. The second supporting frame 106 drives the balancing rod 108 to automatically move upward until it contacts the shaft system workpiece through the second spring 109. It automatically detects whether the shaft system workpiece is balanced, and then automatically detects whether the shaft system workpiece is a standard part. The rotation angle of the motor 202 output shaft and the rising height of the balance bar 108 are linearly related to the thickness of the shaft system workpiece. The thinner the shaft system workpiece, the greater the rotation angle of the motor 202 output shaft, and the higher the balance bar 108 rises. In addition, the first spring 107 has a buffering effect, which can prevent the first roller 203 from not contacting the shaft system workpiece after the balance bar 108 has contacted the shaft system workpiece, causing the balance bar 108 to still be driven by the motor 202 and hard squeeze the shaft system workpiece upward.

[0048] In summary, when the shaft system workpiece is further limited, not only can the balance of the shaft system workpiece be determined at the same time, but also adaptive adjustments can be made according to the thickness of the shaft system workpiece. The operation is simple and convenient, and the function is practical.

[0049] Embodiment 2: Based on embodiment 1, Figure 1 , Fig.10 and Fig.11As shown, it also includes a fixed cylinder 401 symmetrically distributed along the second carrier frame 106, the fixed cylinder 401 is fixedly connected to the second carrier frame 106, a sliding block 402 is slidably connected to the inner side of the fixed cylinder 401, a third spring 403 is fixedly connected between the inner bottom of the fixed cylinder 401 and the bottom of the adjacent sliding block 402, a marking block 404 is fixedly connected to the top of the sliding block 402, and the balance bar 108 is provided with movable grooves symmetrically distributed along the balance bar 108, and the marking block 404 is located in the adjacent movable groove.

[0050] When the balance bar 108 is unbalanced, the downward swing of one side of the balance bar 108 will cause the marking pen on the same side to extend out of the movable slot of the balance bar 108 and contact the shaft workpiece to mark it with color, and the third spring 403 is adaptively compressed. In this way, on the one hand, the marking pen extends out of the movable slot of the balance bar 108, which is convenient for intuitive observation when the balance bar 108 is slightly unbalanced. On the other hand, the marking pen can be used to mark non-standard shaft workpieces, which serves as a reminder, making it easier for operators to distinguish non-standard parts and avoid secondary positioning.

[0051] Embodiment 3: Based on embodiment 1, Figure 1 and Figure 2 As shown, a plurality of second rollers 501 are also included, and the second rollers 501 are rotatably connected to the first carrier 104 .

[0052] By disposing the second roller 501 , the friction between the shaft system workpiece and the first carrier 104 can be reduced, thereby facilitating the rotation of the shaft system workpiece in the subsequent assembly process.

[0053] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
