DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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 intended to limit the present invention.

[0035] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

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

[0037] The dynamic balancing measurement assembly includes a fixing mechanism 3 for mounting a clamping lining plate 8, and a force sensing unit 7 arranged at a contact position between the fixing mechanism 3 and the lining plate 8. The fixing mechanisms 3 are multiple in number and are arranged corresponding to the mounting holes of the lining plate 8. The multiple fixing mechanisms 3 are fixedly mounted on the vibration substrate 5. The vibration substrate 5 drives the fixing mechanisms 3 to randomly shake based on a motion control signal. When the motion state of the lining plate 8 changes, the surface of the force sensing unit 7 receives a change in pressure.

[0038] The trimming and milling mechanism 2 is arranged above the lining plate 8, and the trimming and milling mechanism 2 comprises a milling drill bit, and the milling drill bit moves vertically in the plane where the lining plate 8 is located;

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

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

[0041] In an embodiment of the present invention, an integrated processing device for an alloy steel liner is provided, which is used in the post-processing stage of the alloy steel liner. By setting a balancing milling mechanism 2, a dynamic balancing measurement component and a dynamic balancing evaluation module, the function of dynamic balancing test and correction of the liner is realized. By fixing the liner and performing a vibration test, the unbalanced force on multiple fixed connection points during shaking is determined, and then the weight reduction and balancing can be performed locally according to the balancing requirements to ensure its stability in long-term use and effectively avoid problems such as loose material and rapid wear caused by uneven force on the load-bearing points.

[0042] In one embodiment of the present invention, the purpose is to solve the problem of rapid wear and tear in the prior art. If the liner is used in a vibrating and bumpy environment for a long time, if the force distribution of the liner relative to multiple fixed connection points is uneven, the long-term vibration will lead to accelerated loosening of the connection, and the bolts and nuts at multiple connection points will loosen asynchronously, the wear of the connection will be aggravated and asynchronous, and severe cases may even cause structural deformation and fatigue of the metal material at the connection (relative to a stable balanced distribution connection). Therefore, uniform load distribution control at each point is very necessary for extending the service life, optimizing the maintenance cycle and production safety. In the prior art, the liner is produced in a relatively rough manner, and the connection balancing method it adopts is to analyze and simulate the standard liner model and select multiple suitable installation connection points. However, in fact, in the production process, each individual liner will produce different distribution errors, and these production errors, whether large or small, are not taken into account by the current balancing 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 lining base is produced, the processing device is used to perform balancing processing, and it is fixed on the fixing mechanism 3 (the distribution pattern of the fixing mechanism 3 here is based on the installation hole position of the lining, that is, based on the hole position distribution of the basic balancing of the standard model), and then the fixing mechanism 3 and the lining 8 are driven to vibrate irregularly through the vibration substrate 5, so that each connection obtains a force sensor reading, thereby recording data through the sensor recording unit, and evaluating the distribution of the entire lining under the physical twin simulation of the dynamic balancing simulation unit to generate dynamic balancing milling data (that is, how much weight needs to be subtracted at which position), and the balancing milling drill 2 is controlled by the milling control unit to perform weight distribution balancing management on the lining.

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

[0044] The processing device also includes a vibration control mechanism 6 arranged at a position below the vibration substrate 5, and the vibration control mechanism 6 is composed of a plurality of electromagnetic emission cavity arrays arranged corresponding to the driven magnetic group 510. The electromagnetic emission cavity is provided with an array of electromagnetic parts inclined along the vertical direction. When the electromagnetic parts are energized, they generate repulsive magnetic forces with the magnetic parts.

[0045] In one embodiment of the present invention, a method for realizing the vibration of the vibration substrate 5 is supplemented, and the specific implementation principle is the electromagnetic ejection method, that is, by fixing a driven magnetic group 510 at the bottom of the vibration substrate 5, and separately setting an electromagnetic emission chamber on the base vibration control mechanism 6, when in use, an electromagnetic intensity control signal of a certain intensity is randomly generated within the allowable intensity range, so that the driven magnetic group 510 and the electromagnetic emission chamber have a magnetic repulsion effect, so that the vibration substrate 5 moves upward quickly for a distance and then falls, and this cycle is repeated. Here, a plurality of driven magnetic groups 510 are distributed and arranged, and all can be independently controlled, with the purpose of simulating the multi-directionality of the vibration source to which the lining plate is subjected in the actual use environment.

[0046] like Figures 2 to 4 As 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 a bolt structure, and a hinged structure is provided at the bottom of the mounting bolt 310 for achieving angle control of the mounting bolt 310 . The locking nut 340 is threadedly matched with the mounting bolt 310 for fixing and locking the liner 8 .

[0048] Furthermore, the fixing mechanism 3 further includes a pair of buffer pads 320 disposed on both sides of the lining plate 8, and a protective tube 330 disposed between the pair of buffer pads 320;

[0049] The buffer pad 320 is made of elastic material and is slidably matched with the installation bolt 310 . The protection tube 330 is slidably matched with the installation bolt 310 .

[0050] In one 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 liner 8, a mounting bolt 310 is used. However, at the same time, its purpose is only to measure the experimental mechanical data. In order to protect its structural stability and safety in long-term tests and avoid frequent damage due to tests, a pair of buffer pads 320 and a protective tube 330 are also provided, which are used to protect the mounting bolt 310 and the locking nut 340 respectively, thereby reducing the need for frequent replacement of test fixtures in long-term tests.

[0051] like Figures 7 and 8 As 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 arranged perpendicular to the vibration substrate 5, the lifting column 410 is slidably matched with the vibration substrate 5, and the horizontal cross section of the lifting column 410 is arranged in a cross-shaped structure;

[0053] A connecting piece 420 is disposed at one end of the lifting column 410 away from the vibration substrate 5 . The connecting piece 420 includes a mounting bolt and a locking nut. The fixing mechanism 3 is fixedly connected to the connecting piece 420 via a hinge structure disposed at the bottom of the mounting bolt 310 .

[0054] Furthermore, the lifting mechanism 4 also 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 a horizontal cross section, and the horizontal cross section of the locking block 430 and the lifting column 410 after being assembled is a circular structure, and the locking ring 440 is threadedly matched with the locking block 430;

[0056] The outer diameter of the locking block 430 gradually decreases downward in the vertical direction. The matching portion of the vibration substrate 5 and the lifting column 410 is a double-layer structure. The matching portion of the vibration substrate 5 and the locking block 430 is a circular opening. The side of the matching portion of the vibration substrate 5 and the lifting column 410 away from the locking block 430 is a structure that imitates the lifting column 410.

[0057] In one embodiment of the present invention, an additional auxiliary lifting mechanism 4 is provided to supplement the fixing mechanism 3, and its purpose is to control the lifting and lowering of the fixing mechanism 3. The fixing mechanism 3 needs to be replaced as it wears out during long-term use, so it is usually produced in the form of standard parts. However, there are certain differences in the structures of different linings, so 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 hingedly connected to the fixing mechanism 3 through a connecting piece 420 (can be locked); for the locking ring 440 and the locking block 430, the outer diameter of the locking block 430 is variable, so as the locking ring 440 rotates, the thickness of the gap between the vibration substrate 5 and the lifting column 410 increases, thereby achieving a locking effect.

[0058] like Figure 1 As 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 guide shaft 110 and a second horizontal guide shaft 120 which are cross-arranged in the horizontal direction. The first horizontal guide shaft 110 and the second horizontal guide shaft 120 are slidably matched and a sliding drive member is provided at the connection. A vertical guide shaft 130 is slidably provided on the second horizontal guide shaft 120. The vertical guide shaft 130 is arranged perpendicular to the plane where the vibration substrate 5 is located, and the leveling milling mechanism 2 is slidably provided on the vertical guide shaft 130 along the vertical direction.

[0060] In one embodiment of the present invention, the displacement mode of the trimming and milling mechanism 2 in space is supplemented, that is, a three-axial track guiding mode is adopted to realize the arbitrary positioning and movement of the trimming and milling mechanism 2 in the cubic space, thereby driving the trimming and milling mechanism 2 to the trimming and milling point.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
