Detailed implementation manners

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0036] As Figures 1 to 3 shown, an integrated processing device for alloy steel liners provided by an embodiment of the present invention, the processing device includes a trimming milling mechanism 2, a dynamic balance measurement component, and a dynamic balance evaluation module;

[0037] The dynamic balance measurement component includes a fixing mechanism 3 for installing and clamping the liner 8, and a force sensing unit 7 provided at the contact position between the fixing mechanism 3 and the liner 8. The number of the fixing mechanisms 3 is multiple and is correspondingly arranged with the mounting holes of the liner 8. The multiple fixing mechanisms 3 are fixedly installed on the vibration substrate 5. The vibration substrate 5 drives the fixing mechanism 3 to randomly vibrate based on a motion control signal. When the motion state of the liner 8 changes, the pressure received by the surface of the force sensing unit 7 changes;

[0038] The trimming milling mechanism 2 is arranged above the liner 8. The trimming milling mechanism 2 includes a milling drill bit, and the milling drill bit moves vertically in the plane where the liner 8 is located.

[0039] The dynamic balance evaluation module includes a sensing and recording unit, a dynamic balance simulation unit, and a milling control unit. The sensing and recording unit is electrically connected to the force sensing unit 7 and is used to acquire and record the force data at each fixing mechanism 3 during the movement of the liner.

[0040] The dynamic balance simulation unit is used to perform a simulation based on the force data and a pre-stored mechanical model, evaluate the weight distribution uniformity of the liner 8 based on multiple mounting hole positions, so as to obtain dynamic balance milling data. The milling control unit is electrically connected to the trimming milling mechanism 2 and is used to execute the dynamic balance milling data to control the movement of the trimming milling mechanism 2.

[0041] In the embodiment of the present invention, an integrated processing device for alloy steel liners is provided, which is used in the post-processing stage of alloy steel liners. Through the setting of the trimming milling mechanism 2, the dynamic balance measurement component, and the dynamic balance evaluation module, the functions of dynamic balance testing and correction of the liner are realized. By fixing the liner and performing a vibration test, the unbalanced forces on multiple fixed connection points during its jitter are judged. Furthermore, local weight reduction and balance can be carried out according to the trimming requirements to ensure its stability during long-term use, and effectively avoid problems such as material loosening and rapid wear caused by uneven forces on the force-bearing points.

[0042] In an embodiment of the present invention, the aim is to solve the problem of rapid wear in the prior art. When the lining plate is in a vibrating and bumpy use environment for a long time, if the force distribution of the lining plate relative to multiple fixed connection points is uneven, long-term vibration will accelerate the loosening of the connections. The bolts and nuts at multiple connection points loosen out of sync, and the wear at the connection points is aggravated and out of sync. In severe cases, it may even lead to structural deformation and fatigue of the metal material at the connection points (compared with the stable balanced distribution connection). Therefore, controlling the uniform distribution of loads at each point is very necessary for extending the service life, optimizing the maintenance cycle, and production safety. In the prior art, for the lining plate, it is integrally produced in a relatively rough manner, and the trimming method used for the connection is to analyze and simulate the standard lining plate model and select multiple suitable installation connection points. However, in actual production, each individual lining plate will have different distribution errors, and these production errors, large or small, are not considered by the current trimming method. Therefore, in long-term use, these errors will inevitably lead to the accumulation of adverse effects. The specific implementation method of this embodiment is that after the basic production of the lining plate is completed, the processing device is used for trimming processing. It is fixed on the fixing mechanism 3 (the distribution mode of the fixing mechanism 3 here is set based on the mounting holes of the lining plate, that is, the hole position distribution based on the basic trimming of the standard model). Then, the vibration substrate 5 drives the fixing mechanism 3 and the lining plate 8 to vibrate irregularly, so that force sensing readings are obtained at each connection point. Then, the data is recorded by the sensing recording unit, and under the physical twin simulation of the dynamic balance simulation unit, the distribution of the entire lining plate is evaluated to generate dynamic balance milling data (that is, how much weight needs to be subtracted at which position). The trimming milling drill 2 is controlled by the milling control unit to move, and the weight distribution of the lining plate is trimmed and managed.

[0043] As Figure 5 and Figure 6 shown, as a preferred embodiment of the present invention, a plurality of driven magnetic groups 510 arranged in the vertical direction are distributed at the bottom of the vibration substrate 5, and each driven magnetic group 510 includes a plurality of magnetic members arranged obliquely downward.

[0044] The processing device further includes a vibration control mechanism 6 arranged below the vibration substrate 5. The vibration control mechanism 6 is composed of a plurality of electromagnetic emission cavity arrays corresponding to the driven magnetic groups 510. An array of electromagnetic members arranged obliquely in the vertical direction is provided in the electromagnetic emission cavity. When the electromagnetic members are energized, a repulsive magnetic force acts on the magnetic members.

[0045] In an embodiment of the present invention, the implementation manner of the vibration of the vibration substrate 5 is supplemented. The specific implementation principle is the electromagnetic ejection method, that is, a driven magnetic group 510 is fixedly arranged at the bottom of the vibration substrate 5, and an electromagnetic emission cavity is separately arranged on the base vibration control mechanism 6. During use, an electromagnetic intensity control signal with a certain intensity is randomly generated within an allowable intensity range, so that the driven magnetic group 510 and the electromagnetic emission cavity generate a magnetic repulsive force, causing the vibration substrate 5 to move upward rapidly for a certain distance and then fall. This cycle is repeated. Here, multiple groups of the driven magnetic groups 510 are distributed and can all be independently controlled, aiming to simulate the multi-directionality of the vibration sources received by the lining plate in the actual use environment.

[0046] As Figures 2 to 4 shown, as another preferred embodiment of the present invention, the fixing mechanism 3 specifically includes a mounting bolt 310 and a locking nut 340;

[0047] The mounting bolt 310 is arranged in a bolt structure, and the bottom of the mounting bolt 310 is arranged in a hinged structure for realizing the angle control of the mounting bolt 310. The locking nut 340 is in threaded cooperation with the mounting bolt 310 for fixedly locking the lining plate 8.

[0048] Furthermore, the fixing mechanism 3 further includes a pair of buffer pads 320 arranged on both sides of the lining plate 8, and a protection cylinder 330 arranged at a position between the pair of buffer pads 320;

[0049] The buffer pads 320 are made of elastic materials and are in sliding cooperation with the mounting bolt 310. The protection cylinder 330 is in sliding cooperation with the mounting bolt 310.

[0050] In an embodiment of the present invention, the structure of the fixing mechanism 3 is further described. Since its function is to simulate the installation and use environment of the lining plate 8, the structure of the mounting bolt 310 is adopted. However, at the same time, its purpose is only to measure experimental mechanical data. In order to protect its structural stability and safety during long-term testing and avoid being damaged frequently due to testing, a pair of buffer pads 320 and a protection cylinder 330 are also provided, which are respectively used to protect the mounting bolt 310 and the locking nut 340, reducing the need for frequently replacing test fixing parts during long-term testing.

[0051] As Figures 7 to 8 shown, as a preferred embodiment of the present invention, the processing device further includes a lifting mechanism 4;

[0052] The lifting mechanism 4 includes a lifting column 410 perpendicular to the vibration substrate 5. The lifting column 410 is in sliding cooperation with the vibration substrate 5, and the horizontal cross-section of the lifting column 410 is arranged in a cross-shaped structure;

[0053] One end of the lifting column 410 away from the vibration substrate 5 is provided with a connecting member 420. The connecting member 420 includes a mounting bolt and a locking nut. The fixing mechanism 3 is fixedly connected to the connecting member 420 through a hinge structure provided at the bottom of the mounting bolt 310.

[0054] Furthermore, the lifting mechanism 4 further includes a locking block 430 and a locking ring 440;

[0055] The locking block 430 and the lifting column 410 are arranged in a complementary structure in the horizontal cross-section, and the horizontal cross-section of the locking block 430 and the lifting column 410 after assembly is a circular structure. The locking ring 440 is in threaded cooperation with the locking block 430;

[0056] The outer diameter of the locking block 430 gradually decreases along the vertical direction. The mating part of the vibration substrate 5 and the lifting column 410 is arranged in a double-layer structure. The mating part of the vibration substrate 5 and the locking block 430 is a circular opening. The side of the mating part of the vibration substrate 5 and the lifting column 410 away from the locking block 430 is arranged in a structure imitating the lifting column 410.

[0057] In an embodiment of the present invention, a lifting mechanism 4 for additional assistance of the fixing mechanism 3 is added. Its purpose is to control the lifting of the fixing mechanism 3. The fixing mechanism 3 needs to be replaced as the wear intensifies during long-term use. Therefore, it is usually produced in the way of standard parts. However, there are certain differences in the structures of different liners. Therefore, when installing and fixing, its height may need to be changed, as well as the angle orientation requirements. Therefore, a lifting column 410 with adjustable height is provided here and is hinged (can be locked) to the fixing mechanism 3 through a connecting member 420; for the locking ring 440 and the locking block 430, the outer diameter of the locking block 430 is variable. Therefore, as the locking ring 440 rotates, the thickness of its penetration into the gap between the vibration substrate 5 and the lifting column 410 increases, thereby achieving the locking effect.

[0058] As Figure 1 shown, as another preferred embodiment of the present invention, the processing device further includes a milling positioning device 1;

[0059] The milling positioning device 1 includes a first horizontal guiding shaft 110 and a second horizontal guiding shaft 120 that are cross-arranged in the horizontal direction. The first horizontal guiding shaft 110 and the second horizontal guiding shaft 120 are slidably matched and a sliding driving member is provided at the connection. A vertical guiding shaft 130 is slidably arranged on the second horizontal guiding shaft 120. The vertical guiding shaft 130 is perpendicular to the plane where the vibration substrate 5 is located, and the trimming milling mechanism 2 is slidably arranged on the vertical guiding shaft 130 along the vertical direction.

[0060] In an embodiment of the present invention, the way of displacing the trimming milling mechanism 2 in space is supplemented, that is, a three-axial track guiding method is adopted to achieve its random positioning and movement in a cubic space, so as to drive the trimming milling mechanism 2 to the trimming milling point.

[0061] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
