Description

Technical Field

[0001] This utility model relates to the field of corrugated roller installation technology, specifically a high-precision corrugated roller positioning fixture. Background Technology

[0002] In corrugated cardboard production equipment, the corrugated roller is a core component, and its installation and positioning accuracy directly determines the corrugation forming quality, equipment operation stability, and service life.

[0003] Traditional tooling relies heavily on single structures for positioning corrugated rolls, such as bolt fastening or simple slot positioning, lacking multi-dimensional positioning constraints. During installation, poor alignment accuracy leads to deviations in the corrugated roll axis, resulting in irregular corrugation formation, accelerated roll surface wear, and other malfunctions. Repeated disassembly and adjustments are necessary, severely impacting production efficiency.

[0004] In addition, existing technologies generally lack sufficient adjustment functions during the installation of corrugated rollers. When it is necessary to adjust the mating gap or parallelism of the upper and lower corrugated rollers, it is often necessary to disassemble the entire mounting base and bearing assembly, which is cumbersome and the adjustment accuracy depends on manual experience, making it difficult to achieve precise micro-adjustments. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision corrugated roller positioning fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision corrugated roller positioning fixture, comprising a bearing housing mounting frame, a bearing housing mounting groove on the bearing housing mounting frame, a bearing housing installed in the bearing housing mounting groove, a first bearing installed in the bearing housing, and a first corrugated roller installed through the first bearing, a first positioning component provided between the bearing housing and the bearing housing mounting frame, a mounting seat provided at the top of the bearing housing mounting frame, a positioning adjustment structure provided between the mounting seat and the bearing housing mounting frame, a bearing mounting groove on the mounting seat, a second bearing installed in the bearing housing mounting groove, and a second corrugated roller installed through the second bearing, a bearing housing cover provided at the top of the mounting seat, a positioning pin provided between the bearing housing cover and the mounting seat, and the second bearing fixed in the bearing housing mounting groove by the bearing housing cover.

[0007] The present invention is further configured such that the first positioning component includes an external positioning locking structure, an internal positioning insertion structure, and a top positioning mounting structure.

[0008] The present invention is further configured such that the internal positioning and engagement structure includes a positioning ear, the positioning ear is disposed on the inner side of the bearing seat, a positioning groove is provided in the bearing seat mounting groove, the positioning ear engages in the positioning groove, and an eccentric pin is inserted on the bearing seat mounting bracket. The eccentric pin passes through the positioning groove and engages in the positioning ear. When the bearing seat is installed into the corresponding bearing seat mounting groove, the positioning ear engages in the corresponding positioning groove, thereby achieving precise positioning of the bearing seat when installed in the bearing seat mounting groove. Afterwards, the eccentric pin is inserted from the outside to the inside to lock and fix the positioning ear in the positioning groove. Here, the outside of the eccentric pin can be connected to an existing eccentric pin gear adjustment device, which is prior art and will not be described in detail in the present invention.

[0009] The present invention is further configured such that the external positioning and locking structure includes a locking lug, the locking lug being disposed at the outer bottom end of the bearing housing, and a hydraulic cylinder being hinged to the top outer side of the bearing housing mounting bracket. A locking block is disposed at the bottom end of the hydraulic cylinder, the locking block being rotatable to the middle of the locking lug, and a hydraulic cylinder pin being inserted between the locking lug and the locking lug. After the bearing housing carrying the first corrugated roller is installed into the corresponding bearing housing mounting groove, the hydraulic cylinder is rotated so that the locking block at the bottom end of the hydraulic cylinder rotates to the middle of the locking lug. Then, the hydraulic cylinder pin is inserted from the outside to the inside to lock and fix the locking block between the locking lugs, thereby achieving the locking and fixing of the bearing housing in the bearing housing mounting groove.

[0010] The present invention is further configured such that the top positioning mounting structure includes a positioning slider, the positioning slider being disposed on the inner side of the top of the bearing seat, and a positioning groove being provided in the bearing seat mounting groove. The positioning slider and the positioning groove are slidably engaged. During installation, when the bearing seat is installed into the bearing seat mounting groove, the sliding engagement of the positioning slider and the positioning groove enables the bearing seat to be quickly positioned in the bearing seat mounting groove. Furthermore, the sliding guiding effect between the positioning groove and the positioning slider allows the positioning ear to be accurately and quickly inserted into the positioning groove, thereby improving the accuracy and convenience of the first corrugated roller during installation and increasing installation efficiency.

[0011] The present invention is further configured such that an adjusting slider is provided at the bottom end of the mounting base, and an adjusting groove is provided at the top end of the bearing seat mounting bracket. The adjusting slider is slidably located in the adjusting groove, and the mounting base can be slidably and adjustablely installed on the bearing seat mounting bracket by the cooperation of the adjusting slider and the adjusting groove.

[0012] The present invention is further configured such that the positioning adjustment structure includes an adjustment screw, which is installed in the adjustment groove via a bearing structure. The adjustment slider is threaded onto the adjustment screw. An adjustment motor is provided on the side of the bearing seat mounting bracket. The adjustment motor is connected to the adjustment screw via a transmission. When the adjustment motor is started, the adjustment screw can be rotated. The adjustment slider can be moved in the adjustment groove by the threaded engagement between the adjustment screw and the adjustment slider. The movement of the adjustment slider can control the movement of the mounting base at the top of the bearing seat mounting bracket, thereby enabling the second bearing to drive the movement of the second corrugated roller, and achieving flexible adjustment of the docking accuracy between the second corrugated roller and the first corrugated roller.

[0013] The present invention is further configured such that a fastening pin is threaded on the top of the bearing housing cover, the bottom end of the fastening pin abuts against the second bearing, and a fastening knob is provided on the top. By turning the fastening knob, the rotation of the fastening pin can be controlled, so that the bottom end of the fastening pin is pressed and fixed to the top of the second bearing. In this way, the installation stability of the second bearing in the bearing mounting groove can be further improved.

[0014] Compared with the prior art, the beneficial effects of this utility model are: I. Multi-dimensional positioning ensures installation accuracy This invention achieves high-precision positioning and locking through a triple structure of the first positioning component. In the internal positioning and insertion structure, the positioning ear precisely engages with the positioning groove, and is fixed in place by an eccentric pin to prevent lateral displacement of the bearing seat. The positioning slider of the top positioning and mounting structure slides with the positioning groove, providing guidance and limiting for installation. The external positioning and locking structure, through a hydraulic cylinder, locking block, and hydraulic cylinder pin, achieves longitudinal stability of the bearing seat. Simultaneously, the cooperation between the bearing seat cover, positioning pin, and fastening pin ensures stable installation of the second bearing, guaranteeing the installation accuracy of the corrugated roller from multiple dimensions and reducing subsequent operational deviations.

[0015] II. Step-by-step installation improves ease of operation This invention employs a step-by-step installation process, simplifying the operation. When installing the first corrugated roller, first assemble the first bearing with the bearing housing, then quickly insert it into the bearing housing mounting slot using the positioning slider. Subsequent steps only require inserting the eccentric pin, rotating the hydraulic cylinder, and inserting the hydraulic cylinder pin to complete the fixation. When installing the second corrugated roller, after the second bearing is inserted into the bearing mounting slot, cover the bearing housing with the pressure cap, insert the positioning pin, and tighten the locking knob. Each step is seamlessly connected, requiring no complex adjustments, significantly reducing operational difficulty and improving installation efficiency.

[0016] III. Flexibly adjust and optimize docking effect The positioning and adjustment structure in this invention provides flexible adjustment capabilities for corrugated roller docking. An adjustment motor drives an adjustment screw to rotate, which, through a threaded connection, moves an adjustment slider within an adjustment groove, thereby causing the mounting base to move the second corrugated roller horizontally. This adjustment method eliminates the need for disassembly and reassembly, allowing for real-time fine-tuning according to actual docking requirements. It precisely controls the distance between the second and first corrugated rollers, solving the problem of inconvenient adjustment with traditional tooling. This ensures that the corrugated rollers maintain a good docking state under different working conditions, improving the overall operational stability of the equipment. Attached Figure Description

An adjustment motor 24 is provided on the side of the bearing seat mounting bracket 1, and the adjustment motor 24 is connected to the adjustment screw 23 through a transmission. Start the adjusting motor 24. The adjusting motor 24 can control the rotation of the adjusting screw 23. The threaded engagement between the adjusting screw 23 and the adjusting slider 21 can control the movement of the adjusting slider 21 in the adjusting groove 22. The movement of the adjusting slider 21 can control the movement of the mounting base 6 at the top of the bearing seat mounting bracket 1. In turn, the second bearing 8 can drive the movement of the second corrugated roller 9, so as to flexibly adjust the docking accuracy between the second corrugated roller 9 and the first corrugated roller 5. The adjusting motor 24 adopts an existing motor product with a self-locking function, such as: the adjusting motor 24 is equipped with an electromagnetic braking function, which locks the screw position after adjustment to prevent the mounting base 6 from moving accidentally.

[0027] Please see Figures 1-6 As one embodiment of the bearing housing cover 10: the top of the bearing housing cover 10 is threaded with a fastening pin 25, the bottom end of the fastening pin 25 abuts against the second bearing 8, and the top is provided with a fastening knob 26.

In this way, the installation stability of the second bearing 8 in the bearing mounting groove 7 can be further improved.

[0028] In summary, the working principle and specific workflow of this utility model are as follows: In use, the first bearing 4 is first installed into the corresponding bearing seat 3, and then the bearing seat 3 after the first bearing 4 is installed is installed at both ends of the first corrugated roller 5. Then, the first corrugated roller 5, after the bearing housing 3 is installed, is moved to the bearing housing mounting bracket 1 so that the bearing housing 3 is installed into the corresponding bearing housing mounting groove 2. During this process, the positioning slider 19 will slide within the positioning groove 20 to achieve initial positioning during installation; At the same time, after installation, the movement of the bearing housing 3 in the bearing housing mounting groove 2 can be limited, thus restricting the left and right swaying displacement of the bearing housing 3 in the bearing housing mounting groove 2. During the above installation process, the bearing seat 3 can be quickly positioned in the bearing seat mounting groove 2 by the sliding cooperation of the positioning slider 19 and the positioning groove 20. Furthermore, through the sliding guide effect between the positioning groove 20 and the positioning slider 19, after the bearing seat 3 is installed in the bearing seat mounting groove 2, the positioning ear 12 is precisely and quickly inserted into the positioning groove 13, thereby achieving further positioning of the bearing seat 3 in the bearing seat mounting groove 2. This improves the accuracy and convenience of the first corrugated roller 5 during installation and increases the installation efficiency. Then, insert the eccentric pin 14 to fix the positioning ear 12 in the positioning groove 13; Then, rotate the hydraulic cylinder 16 so that the locking block 17 at the bottom of the hydraulic cylinder 16 rotates to the middle of the locking ear 15. Then, insert the hydraulic cylinder pin 18 from the outside to the inside to lock the locking block 17 between the locking ears 15, thereby locking the bearing seat 3 in the bearing seat mounting groove 2. Next, the second bearing 8 is installed at both ends of the second corrugated roller 9. Then, the second corrugated roller 9 carrying the second bearing 8 is moved to the bearing housing mounting bracket 1, so that the second bearing 8 is engaged in the bearing mounting groove 7 on the corresponding mounting bracket 6. Then, the bearing housing cover 10 is pressed against the top of the second bearing 8, and the bearing housing cover 10 is locked and fixed to the mounting base 6 by the locating pin 11. Then, tighten the fastening knob 26 to control the rotation of the fastening pin 25, so that the bottom end of the fastening pin 25 is pressed and fixed to the top of the second bearing 8. This can further improve the installation stability of the second bearing 8 in the bearing mounting groove 7. It should be noted here that when installing bearings, existing technologies usually equip them with auxiliary structures such as oil rings and bearing outer rings. These structures can form a natural limit with the bearing mounting groove 7. Therefore, this utility model will not elaborate on this part of the limiting structure. Then, the adjusting motor 24 can be started. The adjusting motor 24 can control the rotation of the adjusting screw 23. The threaded engagement between the adjusting screw 23 and the adjusting slider 21 can control the movement of the adjusting slider 21 in the adjusting groove 22. The movement of the adjusting slider 21 can control the movement of the mounting base 6 at the top of the bearing seat mounting bracket 1. This allows the second bearing 8 to drive the movement of the second corrugated roller 9, enabling flexible adjustment of the docking accuracy between the second corrugated roller 9 and the first corrugated roller 5, and improving the positioning accuracy between the first corrugated roller 5 and the second corrugated roller 9.

[0029] In the above process, the synchronous movement between the two adjusting motors 24 can be achieved through the following existing technology: 1. Electronic master-slave control This is the most widely used electrical synchronization scheme. The system designates one motor as the "master motor," whose controller determines its speed and position; the other motor acts as the "slave motor," receiving real-time actual or commanded values ​​(such as torque and speed) from the master motor via a high-speed communication network (such as EtherCAT or Profinet), and quickly adjusting its own output to follow the master motor. Its core lies in a high-performance motion controller and closed-loop servo algorithm, enabling high-precision dynamic synchronization.

[0030] 2. Upper-level controller synchronization When extremely high requirements are placed on multi-axis coordination, a top-level central motion controller (HMC) approach is adopted. This controller acts as a unified brain, generating independent motion commands for each axis based on global planning algorithms (such as electronic virtual spindles), and distributing them in parallel to the drivers of each motor via a synchronous bus. Each motor directly compares its commands with the top-level commands, eliminating the problem of accumulated tracking errors in the master-slave link and achieving true multi-axis coordinated motion. This approach offers optimal synchronization performance and dynamic response, making it suitable for complex systems such as high-end CNC and robotics.

[0031] The present invention preferably adopts an "electronic master-slave control" method.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
