Description

Technical Field

[0001] This invention relates to the field of machine tool combination processing technology, and more specifically, to an automated positioning and installation assembly mechanism for a standard section rack of a construction hoist. Background Technology

[0002] In universal machine tools, the assembly and installation of standard sections and racks of construction hoists mainly utilize the high-precision assembly capabilities of the machine tool to ensure the precise fit between the standard sections and racks. The core principle is to achieve high-precision installation and assembly of the standard sections and racks through the precise positioning of the machine tool.

[0004] When assembling and installing the standard section and rack, the two racks need to be installed with the standard section in different directions, and the standard section and rack have various sizes. Therefore, if size differences occur during the installation process, rework is required later. Moreover, it is difficult to accurately check the standard section and rack in multiple dimensions before installation and assembly, resulting in a high error rate in the installation and assembly.

[0014] In a preferred embodiment, a controller is mounted on one side of one of the side platforms.

[0015] The technical effects and advantages of the present invention.

[0016] 1. This invention employs an end-verification assembly. A reduction motor drives a rotating frame to slide a moving shaft, causing two lifting bars to lift the rack in opposite directions, achieving initial positioning and installation of the rack and standard section ends. A positioning distance sensor senses the position of the rotating frame, and a verification distance sensor detects the distance to the protruding parts at the end of the standard section, enabling dual verification of the rack and standard section ends. This allows for precise calibration of the end-fit dimensions before installation, effectively avoiding rework due to mismatched end dimensions. The invention enables multi-dimensional and precise verification of the standard section and rack before installation, significantly reducing the installation assembly error rate, minimizing subsequent rework, and lowering rework and installation costs in machine tool assembly.

[0017] 2. This invention employs a multi-dimensional verification assembly. After successful end verification, the first electric cylinder pushes the support bar to insert the verification column into the mating hole in the middle of the rack and standard section. Simultaneously, the linkage bar drives the tooth groove verification block and the side tooth groove verification bar to be inserted into the tooth groove in the middle of the rack and the adjacent tooth groove, respectively. The proximity sensor performs proximity detection on the standard section, thereby performing a multi-dimensional comprehensive verification of the hole position, tooth groove, and side position in the middle of the rack and standard section. This achieves a comprehensive and accurate verification of the mating relationship between the rack and the middle of the standard section, significantly reducing assembly errors caused by hole misalignment or tooth groove size deviation, greatly reducing the installation assembly error rate, reducing rework in later processing, and lowering the rework and installation costs of machine tool assembly processing.

[0018] 3. This invention coordinates the actions of the end verification assembly, multi-dimensional verification assembly, and positioning components through a unified controller. The detection signals from the positioning distance sensor, verification distance sensor, and proximity sensor are fed back to the controller in real time, driving the reduction motor, the first electric cylinder, and the second electric cylinder to perform precise actions according to preset parameters. This achieves fully automated assembly line operation from standard section positioning and locking, rack and pinion bidirectional alignment, end double verification to mid-section multi-dimensional verification, greatly reducing manual intervention and subjective misjudgment, and significantly improving the consistency and efficiency of installation and assembly.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings. Example 1

[0030] In this embodiment, as Figure 1 - Figure 8The above describes an automated positioning and installation assembly mechanism for a standard section rack of a construction hoist, comprising a machine table 1, with two side platforms 2 fixed on the upper surface of the machine table 1; two lifting bars 3 installed between the two side platforms 2; an end verification assembly installed on one side of the lifting bars 3; a multi-dimensional verification assembly installed on the other side of the lifting bars 3; and a positioning component installed inside the side platform 2, which is used to position and lock the standard section.

[0031] The operating principle of this embodiment is as follows: the machine tool table 1 supports two side tables 2, and the top center of the machine tool table 1 provides positioning support for the standard section. The positioning component is used to position and lock the standard section. The end verification assembly drives the two racks to move in opposite directions, so that the racks and the ends of the standard section are verified and assembled. At the same time, the end verification assembly drives the lifting bar 3 to move the multi-dimensional verification assembly synchronously until the end verification assembly is successfully verified. Then, the multi-dimensional verification assembly performs multi-dimensional verification and assembly of the racks and the middle of the standard section. This allows for multi-dimensional and accurate verification of the standard section and racks before installation and assembly, which greatly reduces the error rate of installation and assembly, significantly reduces the rework rate in subsequent processing, and greatly reduces the installation and assembly processing cost of the machine tool. Example 2

[0032] In this embodiment, as Figure 1 - Figure 3 As shown, the end-verification assembly includes: two end strips 4, each fixed to one side of the lifting strip 3; a movable shaft 5 is fixed to one end of each end strip 4; a rotating frame 6 is slidably connected to the outer wall of the movable shaft 5; a reduction motor 7 is mounted on one side of the rotating frame 6 and is fixedly connected to the side platform 2; the output end of the reduction motor 7 is used to drive the rotating frame 6 to rotate; a slider 8, fixed to one end of the movable shaft 5 and slidably connected to the side platform 2; a positioning distance sensor 9, mounted above the rotating frame 6 and fixedly connected to the side platform 2; an end block 10, located above the movable shaft 5 and fixedly connected to the end strip 4; a verification strip 11 is fixed to the outer wall of the end strip 4 away from the end block 10; and a verification groove 12, formed on one side of the inner wall of the verification strip 11, with a verification distance sensor 13 mounted on the upper surface of the verification strip 11. The upper surface height of one lifting strip 3 is higher than the upper surface height of the other lifting strip 3. The output end of the reduction motor 7 is fixedly connected to the rotating frame 6. The rotating frame 6 is tilted, and a controller 26 is installed on one side of one of the side platforms 2.

[0033] The operating principle of this embodiment is as follows: A rack is inserted into the two upper end bars 4, with the ends of the racks fitting against the end block 10. Another rack is inserted into the two lower end bars 4, with the two racks facing opposite directions. The controller 26 immediately starts the rotating frame 6 to rotate clockwise. This causes the rotating frame 6 to move the moving shaft 5 upwards, and the other moving shaft 5 to move downwards. The rotating frame 6 then causes the slider 8 to move upwards, guided upwards along the side platform 2. The moving shaft 5 causes the lifting bar 3 to move upwards, and the other lifting bar 3 begins to move downwards. This causes the lifting bar 3 to move the two end bars 4 upwards, which in turn causes the end block 10 to move upwards. The end bar 4 lifts the rack and begins to move upwards, while the other end bar 4 lifts it downwards, causing the two racks to move in opposite directions. The rack end groove is positioned and installed with the protruding part of the standard section end. The end bar 4 then causes the verification bar 11 to move upwards, and the inner wall verification groove 12 of the verification bar 11 is positioned and installed with the protruding part of the standard section end.

[0034] The distance between the rotating frame 6 and the positioning distance sensor 9 is sensed by the positioning distance sensor 9. When the sensed distance value is the same as the distance value set by the controller 26, the vertical positioning installation assembly is in the correct position. When the distance values ​​are different, the vertical positioning installation assembly is in the wrong position. Next, the distance sensor 13 senses the distance to the right side of the protruding part at the end of the standard section. When the distance value sensed by the verification distance sensor 13 is the same as the value set by the controller 26, the protruding part at the end of the standard section is in a qualified installation position. When the values ​​are different, the protruding part at the end of the standard section is in an unqualified installation position. This allows for a double check between the rack and the end of the standard section, and simultaneously achieves the positioning installation assembly. Example 3

[0035] In this embodiment, as Figure 4 - Figure 6 As shown, the multi-dimensional verification assembly includes: a first electric cylinder 14, installed on the other side of the lifting bar 3, with a support bar 15 fixed to the output end of the first electric cylinder 14, and the first electric cylinder 14 is used to push the support bar 15 to move; a verification column 16, fixedly connected to one side of the support bar 15, with a linkage bar 17 fixed to one side of the support bar 15 near its top; a connecting rod 18, fixedly connected to the lower surface of the linkage bar 17, with a toothed verification block 19 fixed to the bottom end of the connecting rod 18, and a side toothed verification strip 20 provided on one side of the toothed verification block 19, and the side toothed verification strip 20 is fixedly connected to the linkage bar 17; and a proximity sensor 21, installed on the upper surface of the linkage bar 17. The lower surface of the side toothed verification strip 20 and the lower surface of the toothed verification block 19 are at the same level, and there is a gap between the verification column 16 and the toothed verification block 19. There is a gap between the tooth groove check block 19 and the side tooth groove check strip 20, and the length of the side tooth groove check strip 20 is greater than the length of the tooth groove check block 19.

[0036] The operating principle of this embodiment is as follows: when the lifting bar 3 moves upward, it drives the first electric cylinder 14 to move upward, and the first electric cylinder 14 drives the support bar 15 to move upward. The support bar 15 drives the verification column 16 to move upward, and the support bar 15 causes the linkage bar 17 to move upward. The linkage bar 17 drives the connecting rod 18 to move upward, and the connecting rod 18 causes the toothed verification block 19 to move upward. At the same time, the linkage bar 17 drives the side toothed verification bar 20 to move upward. After the rack and the end of the standard section have been successfully double-checked, the first electric cylinder 14 pushes the support bar 15 to move, and the support bar 15 drives the verification column 16 to move. The verification column 16 is inserted into the middle of the rack and the standard section for alignment. In the connection hole position, the support bar 15 drives the linkage bar 17 to move, the linkage bar 17 drives the connecting rod 18 to move, and the lower surface of the linkage bar 17 slides against the upper surface of the rack. At the same time, the connecting rod 18 drives the tooth groove alignment block 19 to move, and the tooth groove alignment block 19 is inserted into the middle tooth groove of the rack. At the same time, the linkage bar 17 drives the side tooth groove alignment bar 20 to move, and the side tooth groove alignment bar 20 is inserted into the adjacent tooth groove of the middle tooth groove of the rack. Since the length of the side tooth groove alignment bar 20 is greater than the length of the tooth groove alignment block 19, the left side of the side tooth groove alignment bar 20 is attached to the right side of the inner wall of the standard section.

[0037] The standard section is approached by proximity sensor 21. After proximity sensing, the signal is received by controller 26, indicating that the rack and the middle of the standard section have passed multi-dimensional verification. Once the verification is successful, bolts are inserted into the other two holes of the rack to install and fix the rack and the standard section. If the proximity sensor 21 stops approaching the standard section, it means that the mating hole size of the rack and the standard section is incorrect and cannot be aligned, or that the tooth groove of the rack has a size problem and cannot be aligned, or that the adjacent tooth groove on the middle of the rack has a size problem and cannot be aligned. This completes the multi-dimensional verification and assembly of the rack and the middle of the standard section. After the multi-dimensional verification is successful, the rack and the standard section are assembled, which greatly reduces the assembly and processing cost of the machine tool. Example 4

[0038] In this embodiment, as Figure 7 - Figure 8 As shown, the positioning component includes: multiple pressure columns 22, all of which are slidably installed inside the side platform 2. One end of each pressure column 22 is fixed with a pressure plate 23. A second electric cylinder 24 is provided on one side of the pressure plate 23. The second electric cylinder 24 is fixedly connected to the side platform 2 and is used to push the pressure plate 23 to move. The other end of each pressure column 22 is fixed with a docking column 27. The outer diameter of the docking column 27 is smaller than the outer diameter of the pressure column 22.

[0039] The operating principle of this embodiment is as follows: by activating two second electric cylinders 24, the output ends of the two second electric cylinders 24 respectively push the two pressure plates 23 to the right, so that the two pressure plates 23 come closer to each other and squeeze. The pressure plates 23 drive multiple pressure columns 22 to move to the right synchronously. The pressure columns 22 slide along the inner wall of the side platform 2, so that the pressure columns 22 squeeze onto the standard section. At the same time, the pressure columns 22 drive the docking column 27 to move, and the docking column 27 inserts into the interior of the standard section to position and lock the standard section.

[0040] In this embodiment, as Figure 1 As shown, multiple base blocks 25 are fixed to the top of the machine tool table 1, and the multiple base blocks 25 are arranged in a rectangular distribution. The multiple base blocks 25 provide positioning support for the lower surface of the standard section, thereby improving the stability of the standard section when it is placed.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
