Description

Technical Field

[0001] This invention relates to the technical field of casting processing equipment, and in particular to a large wind turbine bearing housing casting processing equipment. Background Technology

[0002] Floor-type boring and milling machines are powerful heavy-duty CNC machine tools that integrate multiple processing functions such as boring, milling, drilling, and tapping. They are suitable for processing large and heavy workpieces, such as bearing housings for large wind power equipment.

[0003] The core feature of the floor-type boring and milling machine is that the machine tool column moves longitudinally on the base, the spindle box moves vertically on the column, and the huge workpiece is fixedly mounted on the floor-type work platform in front. During this process, the spindle box moves telescopically through the slide mechanism to perform boring or milling operations.

[0004] However, in some deep machining scenarios, the ram mechanism needs to extend a large distance. In this case, the ram mechanism has a large weight at the end, causing the end to naturally droop. In addition, the ram mechanism may be subject to the resistance of the casting during machining, which will generate a load force perpendicular to the ram mechanism. Over time, this can easily cause the ram mechanism to deviate, thereby affecting the machining accuracy of the machining equipment.

[0005] Therefore, improvements to existing technologies are necessary.

[0006] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Summary of the Invention

[0007] This invention provides a large-scale wind turbine bearing housing casting processing equipment to solve the problem in the prior art where the ram mechanism is prone to structural displacement due to uneven load, thus affecting processing accuracy.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A large-scale wind turbine bearing housing casting processing equipment, comprising:

[0010] Equipment body;

[0011] A ram mechanism is slidably mounted on the equipment body, and the ram mechanism is provided with a spindle assembly for processing castings;

[0012] A vertical correction mechanism is installed on the equipment body and abuts against the slide mechanism. It is used to apply upper or lower pressure to the slide mechanism in the vertical direction to keep the slide mechanism horizontal.

[0013] A lateral correction mechanism is provided on the equipment body and abuts against the slide mechanism. It is used to apply left or right pressure to the slide mechanism in the lateral direction so that the slide mechanism remains in a neutral position.

[0014] The system includes a detection and control system, which is connected to the vertical correction mechanism and the horizontal correction mechanism, respectively. It is used to detect the offset direction of the slide block mechanism and, based on the offset direction, drive the vertical correction mechanism to output upper pressure, drive the vertical correction mechanism to output lower pressure, drive the horizontal correction mechanism to output left pressure, or drive the horizontal correction mechanism to output right pressure.

[0015] Preferably, the vertical correction mechanism includes:

[0016] A vertical reciprocating module is installed on the device body and is used to output reciprocating motion along the vertical direction;

[0017] A vertical correction sleeve is provided, which is connected to the vertical reciprocating module and sleeved on the outside of the slide mechanism. The vertical correction sleeve has an upper correction surface and a lower correction surface. The upper correction surface abuts against the upper surface of the slide mechanism, and the lower correction surface abuts against the lower surface of the slide mechanism. The inner walls of the two sides of the vertical correction sleeve in the horizontal direction are separated from the slide mechanism.

[0018] Preferably, the vertical correction mechanism further includes a first angle compensation component, which includes:

[0019] The first hinge seat is disposed on the vertical correction sleeve;

[0020] And a second hinge seat, disposed on the vertical reciprocating module, and hinged to the first hinge seat. The first hinge seat and the second hinge seat rotate relative to each other along a first hinge axis. The first hinge axis is horizontally disposed and perpendicular to the movement trajectory of the slide mechanism.

[0021] Preferably, the lateral correction mechanism includes:

[0022] A transverse reciprocating module is installed on the device body for outputting transverse reciprocating motion;

[0023] A lateral correction sleeve is provided, which is connected to the lateral reciprocating module and sleeved on the outside of the ram mechanism. The lateral correction sleeve has a left correction surface and a right correction surface. The left correction surface abuts against the left side of the ram mechanism, and the right correction surface abuts against the right side of the ram mechanism. The inner walls of the two sides of the lateral correction sleeve in the vertical direction are separated from the ram mechanism.

[0024] Preferably, the lateral correction mechanism further includes a second angle compensation component, the second angle compensation component comprising:

[0025] The third hinge seat is disposed on the transverse correction sleeve;

[0026] A fourth hinge seat is disposed on the transverse reciprocating module and is hinged to the third hinge seat. The third hinge seat and the fourth hinge seat rotate relative to each other along the second hinge axis, which is vertically arranged and perpendicular to the movement trajectory of the slide mechanism.

[0027] Preferably, it further includes an adjustment mechanism, the adjustment mechanism comprising:

[0028] The guide rail assembly is disposed on the device body;

[0029] The mounting base is slidably disposed on the guide rail assembly, and the vertical correction mechanism and the horizontal correction mechanism are disposed on the mounting base;

[0030] And a drive component, disposed on the device body and connected to the mounting base, for driving the mounting base to reciprocate along the moving direction of the slide mechanism.

[0031] Preferably, the detection and monitoring system includes:

[0032] The detection module is provided on the device body with an exposure port for the reciprocating extension and retraction of the slide mechanism. The detection module is disposed on the outer surface of the device body and located at the edge of the exposure port. It is used to detect the offset D1 of the slide mechanism in the vertical direction and to detect the offset D2 of the slide mechanism in the horizontal direction.

[0033] The control module is connected to the detection module, the vertical correction mechanism, and the horizontal correction mechanism respectively. The control module controls the start and stop of the vertical correction mechanism based on the offset D1, and controls the start and stop of the horizontal correction mechanism based on the offset D2.

[0034] Preferably, the detection module includes:

[0035] A vertical distance sensor is installed on the device body and located above or below the slide mechanism. It is used to detect the vertical offset of the slide mechanism and generate an offset amount D1.

[0036] A lateral distance sensor is provided on the device body and located on one side of the slide mechanism in the horizontal direction, for detecting the horizontal offset of the slide mechanism and generating an offset amount D2.

[0037] Preferably, the detection module further includes:

[0038] A vertical pressure sensing element is disposed in the lateral correction mechanism, abutting and cooperating with the upper and lower surfaces of the slide mechanism, and connected to the control module;

[0039] A lateral pressure sensing element is disposed on the vertical correction mechanism, and abuts against the two side surfaces of the slide block mechanism in the horizontal direction, and is connected to the control module.

[0040] When the slide mechanism deviates vertically, the slide mechanism squeezes the vertical pressure sensing element and generates a pressure deviation signal D3. The control module controls the vertical correction mechanism to start based on the pressure deviation signal D3 until the pressure deviation signal D3 falls into the preset deviation range value.

[0041] When the ram mechanism shifts laterally, it presses against the lateral pressure sensing element and generates a pressure deviation signal D4. The control module controls the lateral correction mechanism to start based on the pressure deviation signal D4 until the pressure deviation signal D4 falls within a preset deviation range.

[0042] Preferably, both the vertical pressure sensing element and the lateral pressure sensing element comprise:

[0043] A thin-film sensor is disposed in the vertical correction mechanism or the horizontal correction mechanism;

[0044] And an elastic support member, one side of which is disposed on the thin film sensor and the other side abuts and cooperates with the slide mechanism. When the slide mechanism is offset, it drives the elastic support member to deform and applies elastic force to the thin film sensor.

[0045] Compared with the prior art, the present invention has the following beneficial effects:

[0046] The large wind turbine bearing housing casting processing equipment provided by this invention has a detection and control system that can dynamically monitor the offset direction of the ram mechanism and control the vertical and horizontal correction mechanisms to start based on the offset direction. At this time, the vertical correction mechanism can output pressure opposite to the offset direction, thereby keeping the ram mechanism horizontal and reducing the offset in the vertical direction. Alternatively, the horizontal correction mechanism can apply a horizontal thrust to the ram mechanism in the horizontal direction, thereby reducing the ram offset problem caused by horizontal processing. In this way, the ram mechanism can be kept in a neutral position. Therefore, with the cooperation of the vertical correction mechanism, the horizontal correction mechanism, and the detection and control system, the ram mechanism is not easily subjected to uneven loads and is not easily offset in structure, thus solving the problem of processing accuracy.

[0047] The present invention has other features and advantages, which will be apparent from or will be set forth in detail in the accompanying drawings and the following detailed description, which together serve to explain the particular principles of the invention. Attached Figure Description

[0065] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

When a component is considered to be "set" on another component, it can be directly set on the other component or there may be an intermediate component present simultaneously.

They are used only for the purpose of describing the present invention and are not intended to indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of the present invention.

[0068] The following is in conjunction with the appendix Figure 1-5 The technical solution of the present invention will be further illustrated through specific embodiments.

[0069] Please refer to Figure 1 and Figure 2 This invention provides a large wind turbine bearing housing casting processing equipment, including an equipment body 1, a slide mechanism 2, a vertical correction mechanism 3, a horizontal correction mechanism 4, and a detection and control system.

[0070] The slide mechanism 2 is slidably mounted on the equipment body 1, and the slide mechanism 2 is equipped with a spindle assembly for processing castings. The vertical correction mechanism 3 is mounted on the equipment body 1 and abuts against the slide mechanism 2. The vertical correction mechanism 3 is used to apply upper or lower pressure to the slide mechanism 2 in the vertical direction to keep the slide mechanism 2 horizontal. In addition, the horizontal correction mechanism 4 is mounted on the equipment body 1 and abuts against the slide mechanism 2. The horizontal correction mechanism 4 is used to apply left or right pressure to the slide mechanism 2 in the horizontal direction to keep the slide mechanism 2 in a neutral position.

[0071] In addition, the detection and control system is connected to the vertical correction mechanism 3 and the horizontal correction mechanism 4 respectively. The detection and control system is used to detect the offset direction of the slide mechanism 2, and drive the vertical correction mechanism 3 to output upper pressure, drive the vertical correction mechanism 3 to output lower pressure, drive the horizontal correction mechanism 4 to output left pressure, or drive the horizontal correction mechanism 4 to output right pressure according to the offset direction.

[0072] Specifically, the equipment body 1 typically includes a rotary worktable, a frame, and a displacement mechanism. The worktable is located in front of the frame and is used to prevent castings from moving. The displacement mechanism is mounted on the frame, and the slide mechanism 2 is connected to the displacement mechanism. The displacement mechanism is used to drive the slide mechanism 2 to move up, down, translate, and extend in three-dimensional space. Specifically, for ease of understanding, a three-dimensional rectangular coordinate system is established here, including horizontally set x-axis and y-axis, and also including a z-axis set along the vertical direction. The displacement mechanism includes at least three sets of linear modules, such as linear motor modules or lead screw motor modules that can output reciprocating linear motion. The three sets of linear modules are connected in sequence and output reciprocating motion in the x-axis, y-axis, and z-axis directions, respectively.

[0073] At this time, by setting the slide mechanism 2 on the linear module, under the superposition of the movement of the three linear modules, the slide mechanism 2 can translate along the y-axis and z-axis. When the slide mechanism 2 moves along the y-axis, it can change the processing position of the slide mechanism 2 on the casting. When the slide mechanism 2 moves along the z-axis, it can change the processing height of the slide mechanism 2. In addition, when the slide mechanism 2 moves along the x-axis, it can extend and retract to change the processing depth of the casting. Here, no specific restrictions are placed on the processing path of the equipment body 1.

[0074] Based on the above settings, the slide mechanism 2 can reciprocate in three-dimensional space to perform machining operations on the casting. However, during the machining process, since the slide mechanism 2 needs to extend along the x-axis to the outside of the equipment body 1, and since the extended end of the slide mechanism 2 usually needs to be equipped with a cutting head, its self-weight is relatively large. As the extension distance increases, the extended end of the slide mechanism 2 will sink, resulting in a positional deviation of the slide mechanism 2. In addition, during the machining process, since the machining path of the bearing seat is relatively complex, the slide mechanism 2 will also be subject to machining resistance from the casting during the movement. This machining resistance may be vertically downward or vertically upward, or it may apply resistance to both sides of the slide mechanism 2 in the horizontal direction. Therefore, the slide mechanism 2 has the possibility of offset in four directions: up, down, left, and right. Therefore, in order to ensure machining accuracy, the slide mechanism 2 needs to maintain a neutral position as much as possible.

[0075] Based on this, combined Figure 2 The vertical correction mechanism 3 is located inside the frame and above or below the slide mechanism 2. The vertical correction mechanism 3 can output positive or negative movement along the z-axis and push the slide mechanism 2 to move in the vertical direction during this process. This can counteract the vertical offset of the slide mechanism 2 and reduce the vertical displacement deviation of the slide mechanism 2.

[0076] In addition, the lateral correction mechanism 4 is located inside the frame and on the left or right side of the slide mechanism 2. The lateral correction mechanism 4 can output forward or reverse movement along the y-axis, and in this process, it can push the slide mechanism 2 to move in the lateral y-axis direction, thus counteracting the horizontal offset of the slide mechanism 2 and reducing the lateral displacement deviation of the slide mechanism 2.

[0077] Therefore, under the combined action of the vertical correction mechanism 3 and the horizontal correction mechanism 4, the offset of the slide mechanism 2 in the four directions of up, down, left and right can be reduced. On this basis, the detection and control system can detect the specific offset direction of the slide mechanism 2, and thus activate the vertical correction mechanism 3 and the horizontal correction mechanism 4 accordingly, so that the slide mechanism 2 can be kept in a neutral position.

[0078] The large wind turbine bearing housing casting processing equipment provided in this application embodiment solves the problem that the slide mechanism 2 is prone to structural displacement due to uneven load, which in turn affects the processing accuracy, through the cooperation of the vertical correction mechanism 3, the horizontal correction mechanism 4, and the detection and control system.

[0079] Continue to refer to Figure 2 and Figure 3In some embodiments, the vertical correction mechanism 3 includes a vertical reciprocating module 31 and a vertical correction sleeve 32. The vertical reciprocating module 31 is disposed on the device body 1 and is used to output reciprocating motion along the vertical direction. The vertical correction sleeve 32 is connected to the vertical reciprocating module 31 and is sleeved on the outside of the slide mechanism 2. The vertical correction sleeve 32 has an upper correction surface 321 and a lower correction surface 322. The upper correction surface 321 abuts against the upper surface of the slide mechanism 2, and the lower correction surface 322 abuts against the lower surface of the slide mechanism 2. The inner walls of the two sides of the vertical correction sleeve 32 in the horizontal direction are separated from the slide mechanism 2.

[0080] Specifically, the end of the slide mechanism 2 extending into the equipment body 1 is defined as the extended end, and the other end is the inner end. The vertical correction mechanism 3 acts on the inner end of the slide mechanism 2. The vertical reciprocating module 31 can be a reciprocating module structure that can output reciprocating linear motion, such as an electric telescopic cylinder or a hydraulic telescopic cylinder. In this embodiment, the vertical reciprocating module 31 adopts a double-acting hydraulic cylinder. The vertical reciprocating module 31 is fixedly installed on the equipment body 1, and its telescopic rod extends along the z-axis. At this time, oil can be alternately injected into the two chambers of the hydraulic cylinder, and forward and reverse thrust output is achieved by the action of hydraulic pressure. The specific model of the vertical reciprocating module 31 can be adjusted according to actual needs, and no specific restrictions are made here.

[0081] Based on this, the vertical correction sleeve 32 has a rectangular sleeve structure with a rectangular sleeve interface inside. The vertical correction sleeve 32 is sleeved on the outside of the slide block mechanism 2 through the sleeve interface, and the vertical correction sleeve 32 is connected to the telescopic rod of the vertical reciprocating module 31. At this time, under the drive of the vertical reciprocating module 31, the vertical correction sleeve 32 can be driven to move back and forth.

[0082] At this time, the upper correction surface 321 is formed on the upper surface of the sleeve interface of the vertical correction sleeve 32, and the lower correction surface 322 is formed on the lower surface of the sleeve interface of the vertical correction sleeve 32. The upper correction surface 321 is located above the lower correction surface 322, and the two are parallel to each other.

[0083] Based on the above settings, when the extended end of the slide mechanism 2 shifts downward, the vertical reciprocating module 31 drives the vertical correction sleeve 32 to descend, and the upper correction surface 321 abuts against the upper surface of the slide mechanism 2, thereby pushing the inner end of the slide mechanism 2 to move downward, causing the extended end of the slide mechanism 2 to tilt upward, thus offsetting the downward shift of the slide mechanism 2.

[0084] Correspondingly, when the slide mechanism 2 shifts upward, the vertical reciprocating module 31 drives the vertical correction sleeve 32 to rise, and the lower correction surface 322 abuts against the lower surface of the slide mechanism 2, thereby pushing the extended end of the slide mechanism 2 to move downward, thus offsetting the positional deviation of the slide mechanism 2 shifting upward.

[0085] It should be explained that while the sliding ram mechanism 2 is generating vertical offset, it may also generate lateral offset. In this case, the opening size of the sleeve should be larger than the perimeter of the sliding ram mechanism 2. This allows the inner walls of both sides of the straightening sleeve in the horizontal direction to separate from the sliding ram mechanism 2. Based on this setting, the sliding ram mechanism 2 can be provided with the freedom of lateral swing within the vertical straightening sleeve 32, thereby avoiding interference and influence of the vertical straightening mechanism 3 on the straightening action of the lateral straightening mechanism 4.

[0086] Therefore, by setting up the vertical reciprocating module 31 and the vertical correction sleeve 32, the vertical displacement of the slide mechanism 2 can be pushed or pulled in the vertical direction through linear reciprocating motion, thereby realizing position compensation in the vertical direction and keeping the slide mechanism 2 in a neutral position in the vertical direction.

[0087] Furthermore, continue to refer to Figure 3 When the ram mechanism 2 generates vertical correction mechanism 3, it also includes a first angle compensation component 6, which includes a first hinge seat 61 and a second hinge seat 62.

[0088] The first hinge seat 61 is disposed on the vertical correction sleeve 32, and the second hinge seat 62 is disposed on the vertical reciprocating module 31 and is hinged to the first hinge seat 61. The first hinge seat 61 and the second hinge seat 62 rotate relative to each other along the first hinge axis. The first hinge axis is horizontally disposed and perpendicular to the movement trajectory of the slide mechanism 2.

[0089] Specifically, the first hinge seat 61 is fixedly installed on the vertical correction sleeve 32, and the second hinge seat 62 is fixedly installed on the telescopic rod of the vertical reciprocating module 31. The first hinge axis is parallel to the y-axis. At this time, the first hinge axis is set horizontally and is perpendicular to the movement trajectory of the slide mechanism 2. Under the guidance of the first hinge axis, the vertical correction sleeve 32 can swing up and down to adapt to the vertical offset angle of the slide mechanism 2. This allows the upper correction surface 321 or the lower correction surface 322 to fit tightly against the slide mechanism 2, making the correction action output by the vertical reciprocating module 31 more stable.

[0090] In some embodiments, refer to Figure 2 and Figure 4 The lateral correction mechanism 4 includes a lateral reciprocating module 41 and a lateral correction sleeve 42.

[0091] The transverse reciprocating module 41 is disposed on the equipment body 1 and is used for transverse output reciprocating motion. The transverse correction sleeve 42 is connected to the transverse reciprocating module 41 and is sleeved on the outside of the slide mechanism 2. The transverse correction sleeve 42 has a left correction surface 421 and a right correction surface 422. The left correction surface 421 abuts and cooperates with the left side of the slide mechanism 2, and the right correction surface 422 abuts and cooperates with the right side of the slide mechanism 2. The inner walls of the two sides of the transverse correction sleeve 42 in the vertical direction are separated from the slide mechanism 2.

[0092] It is understandable that the specific structure of the transverse reciprocating module 41 is the same as that of the vertical reciprocating module 31. In addition, the specific structure of the transverse correction sleeve 42 is the same as that of the vertical correction sleeve 32. The difference is that the transverse reciprocating module 41 is horizontally installed on the equipment body 1, and the telescopic cylinder of the transverse reciprocating module 41 is parallel to the y-axis.

[0093] Based on this, the transverse correction sleeve 42 also has a rectangular sleeve structure with a rectangular sleeve interface inside. The transverse correction sleeve 42 is sleeved on the outside of the slide block mechanism 2 through the sleeve interface, and the transverse correction sleeve 42 is connected to the telescopic rod of the transverse reciprocating module 41. Under the drive of the transverse reciprocating module 41, the transverse correction sleeve 42 can be driven to move forward or backward along the y-axis.

[0094] At this point, the horizontally opposite two surfaces of the sleeve hole inside the transverse correction sleeve 42 are defined as the left correction surface 421 and the right correction surface 422, respectively, and the two are parallel to each other.

[0095] Based on the above settings, when the extended end of the slide mechanism 2 shifts to the left, the transverse reciprocating module 41 drives the vertical correction sleeve 32 to move to the left, and makes the right correction surface 422 abut against the right side surface of the slide mechanism 2, thereby pushing the inner end of the slide mechanism 2 to move to the left, and causing the extended end of the slide mechanism 2 to move to the right, thus offsetting the positional deviation of the slide mechanism 2 shifting to the left.

[0096] Correspondingly, when the extended end of the slide mechanism 2 shifts to the right, the transverse reciprocating module 41 drives the vertical correction sleeve 32 to move to the right, and makes the left correction surface 421 abut against the left side surface of the slide mechanism 2, thereby pushing the inner end of the slide mechanism 2 to move to the right, and causing the extended end of the slide mechanism 2 to move to the left, thus offsetting the positional deviation of the slide mechanism 2 shifting to the right.

[0097] It should be explained that while the ram mechanism 2 is generating lateral offset, it may also generate vertical offset. In this case, by making the opening size of the sleeve interface larger than the perimeter of the ram mechanism 2, the inner walls of both sides of the lateral correction sleeve 42 in the vertical direction are separated from the ram mechanism 2. Based on this setting, the ram mechanism 2 can be provided with vertical swing freedom within the lateral correction sleeve 42, thereby avoiding interference and influence of the lateral correction mechanism 4 on the correction action of the vertical correction mechanism 3.

[0098] In summary, by reserving space on the vertical correction sleeve 32 for the lateral swing of the slide mechanism 2, and reserving space on the horizontal correction sleeve 42 for the vertical swing of the slide mechanism 2, interference between the vertical correction mechanism 3 and the horizontal correction mechanism 4 can be avoided, and their correction actions can be coordinated. When the slide mechanism 2 simultaneously undergoes vertical and horizontal offset, the slide mechanism 2 can still maintain a neutral position as a whole.

[0099] Furthermore, continue to refer to Figure 4 The lateral correction mechanism 4 also includes a second angle compensation component 7, which includes a third hinge seat 71 and a fourth hinge seat 72. The third hinge seat 71 is disposed on the lateral correction sleeve 42, and the fourth hinge seat 72 is disposed on the lateral reciprocating module 41 and is hinged to the third hinge seat 71. The third hinge seat 71 and the fourth hinge seat 72 rotate relative to each other along a second hinge axis, which is vertically arranged and perpendicular to the movement trajectory of the slide mechanism 2.

[0100] Specifically, the third hinge seat 71 is fixedly installed on the transverse correction sleeve 42, and the fourth hinge seat 72 is fixedly set on the telescopic rod of the transverse reciprocating module 41. The second hinge axis is parallel to the z-axis direction. At this time, the second hinge axis is set vertically and is perpendicular to the movement trajectory of the slide mechanism 2. Under the guidance of the second hinge axis, the transverse correction sleeve 42 can swing left and right in the horizontal plane, thereby adapting to the left and right offset angle of the slide mechanism 2. This allows the left correction surface 421 or the right correction surface 422 to fit tightly against the slide mechanism 2, making the power transmission output by the transverse reciprocating module 41 more stable.

[0101] Reference Figure 2 During the movement of the ram mechanism 2, its center of gravity moves and the inner end will also be displaced accordingly. In order to prevent the vertical correction mechanism 3 and the horizontal correction mechanism 4 from loosening the ram mechanism 2, in some embodiments, an adjustment mechanism 8 is also included. The adjustment mechanism 8 includes a guide rail assembly 81, a mounting base 82 and a drive assembly 83.

[0102] The guide rail assembly 81 is disposed on the equipment body 1, the mounting base 82 is slidably disposed on the guide rail assembly 81, the vertical correction mechanism 3 and the horizontal correction mechanism 4 are disposed on the mounting base 82, and the drive assembly 83 is disposed on the equipment body 1 and connected to the mounting base 82, for driving the mounting base 82 to move back and forth along the moving direction of the slide mechanism 2.

[0103] Specifically, the guide rail assembly 81 is fixedly mounted on the frame and extends along the x-axis. At this time, a slider can be set on the mounting base 82 and slidably mounted on the guide rail assembly 81. Under the guidance of the guide rail assembly 81, the mounting base 82 can slide along the x-axis. In addition, the vertical correction mechanism 3 and the horizontal correction mechanism 4 are mounted on the mounting base 82. Therefore, the mounting base 82 can drive the vertical correction mechanism 3 and the horizontal correction mechanism 4 to move synchronously during the movement process.

[0104] Based on this, the drive assembly 83 can adopt a linear motor, a lead screw linear module, a cylinder element or a hydraulic cylinder, etc. The specific structure of the drive assembly 83 can be adjusted according to actual needs, and no specific restrictions are made here. The drive assembly 83 is used to output reciprocating linear motion along the x-axis direction, thereby driving the mounting base 82 to move. At this time, by controlling the synchronous displacement of the drive assembly 83 and the slide mechanism 2, the vertical correction mechanism 3 and the horizontal correction mechanism 4 can be driven to move synchronously with the inner end of the slide mechanism 2, thereby making the vertical correction mechanism 3 and the horizontal correction mechanism 4 follow the inner end to move, which can effectively prevent the vertical correction mechanism 3 and the horizontal correction mechanism 4 from loosening from the slide mechanism 2.

[0105] Reference Figure 1 , Figure 2 and Figure 5 In some embodiments, the detection and monitoring system includes a detection module 5 and a control module.

[0106] The equipment body 1 is provided with an opening for the reciprocating extension and retraction of the slide mechanism 2. The detection module 5 is set on the outer surface of the equipment body 1 and located at the edge of the opening. It is used to detect the vertical offset D1 of the slide mechanism 2 and the horizontal offset D2 of the slide mechanism 2.

[0107] Based on this, the control module is connected to the detection module 5, the vertical correction mechanism 3, and the horizontal correction mechanism 4 respectively. The control module controls the start and stop of the vertical correction mechanism 3 based on the offset D1, and controls the start and stop of the horizontal correction mechanism 4 based on the offset D2.

[0108] Specifically, the control module typically includes a main control chip, which has a receiving end and an output end. The main control chip has functions such as analyzing, calculating and processing signals. The specific principle of the main control chip is not limited here.

[0109] Based on this, the receiving end of the main control chip is connected to the detection module 5, and the output end of the main control chip is connected to the vertical correction mechanism 3 and the horizontal correction mechanism 4 respectively. When the sliding ram mechanism 2 deviates, it sends the offset D1 and offset D2 to the receiving end of the main control chip. At this time, the main control chip analyzes and processes the data to generate a start signal, and selectively sends the start signal to the vertical correction mechanism 3 or the horizontal correction mechanism 4 through the output end. Specifically, when there is an offset D1, the main control chip sends the start signal to the vertical correction mechanism 3, and when there is an offset D2, the main control chip sends the start signal to the horizontal correction mechanism 4.

[0110] Based on the above settings, with the cooperation of the detection module 5 and the control module, the vertical correction mechanism 3 and the horizontal correction mechanism 4 can be accurately driven to start, thereby realizing the correction function on their own. The equipment is more intelligent and is conducive to realizing the dynamic correction function.

[0111] In some embodiments, combined with Figure 5 The detection module 5 includes a vertical distance sensor 51 and a horizontal distance sensor 52. The vertical distance sensor 51 is located on the device body 1 and above or below the slide mechanism 2. It is used to detect the vertical offset of the slide mechanism 2 and generate an offset amount D1. The horizontal distance sensor 52 is located on the device body 1 and on one side of the slide mechanism 2 in the horizontal direction. It is used to detect the horizontal offset of the slide mechanism 2 and generate an offset amount D2.

[0112] Specifically, the vertical distance sensor 51 and the horizontal distance sensor 52 have the same structure. Both can be optical distance sensors, infrared distance sensors, or ultrasonic distance sensors. Before obtaining the offset, the vertical distance sensor 51 and the horizontal distance sensor 52 need to be calibrated respectively. Taking the vertical distance sensor 51 as an example, the vertical distance sensor 51 is fixedly installed on the outer surface of the frame, and the measuring light or measuring sound wave emitted by it is set vertically. At this time, the measuring light or measuring sound wave can be applied to the sliding ram mechanism 2 before the sliding ram mechanism 2 extends out of the equipment body 1 to obtain the basic distance value h1. Then, after the sliding ram mechanism 2 slides out of the equipment body 1, the parameters of the vertical distance sensor 51 are read to obtain h2. By subtracting h2 from h1, the offset D1 can be obtained.

[0113] At this point, it can be further set that: if the offset D1 is positive, it indicates that the slide mechanism 2 is offset downwards, and when D1 is negative, it indicates that the slide mechanism 2 is offset upwards. At this time, the main control chip can control the vertical reciprocating module 31 to output downward or upward pressure according to the actual offset direction of the slide mechanism 2, thereby achieving accurate correction. It can be understood that the cooperation method of the lateral correction mechanism 4 and the lateral distance sensor 52 is the same as the above principle. By judging the positive or negative value of D2, the offset direction of the slide mechanism 2 is determined, and then the lateral reciprocating module 41 is controlled to output left or right pressure accordingly, thus achieving the correction effect of the slide mechanism 2 in the horizontal direction.

[0114] Based on the above settings, with the joint cooperation of the vertical distance sensor 51, the horizontal distance sensor 52 and the control module, the offset direction of the slide block mechanism 2 can be accurately identified. Based on the specific offset direction, the horizontal correction mechanism 4 and the vertical correction mechanism 3 can be precisely controlled to correct the offset direction of the slide block mechanism 2, thereby achieving precise correction control action.

[0115] After the vertical distance sensor 51 and the horizontal distance sensor 52 know the offset direction of the ram mechanism 2, the vertical correction mechanism 3 and the horizontal correction mechanism 4 also need to precisely control the output displacement distance so that the ram mechanism 2 can maintain a neutral position in the vertical and horizontal directions.

[0116] Based on this, refer to Figure 3 and Figure 4 The detection module 5 also includes a vertical pressure sensing element 53 and a horizontal pressure sensing element 54.

[0117] The vertical pressure sensing element 53 is disposed on the horizontal correction mechanism 4, and abuts against the upper and lower surfaces of the slide mechanism 2, and is connected to the control module. The horizontal pressure sensing element 54 is disposed on the vertical correction mechanism 3, and abuts against the two sides of the slide mechanism 2 in the horizontal direction, and is connected to the control module.

[0118] In some embodiments, the number of vertical pressure sensing elements 53 is set to two, and the two vertical pressure sensing elements 53 are respectively disposed on the inner walls of the two sides of the transverse correction sleeve 42 in the vertical direction.

[0119] At this time, when the slide mechanism 2 shifts vertically, the slide mechanism 2 will squeeze the vertical pressure sensing element 53 and generate a pressure deviation signal D3. The vertical pressure sensing element 53 sends the pressure deviation signal D3 to the receiving end of the main control chip. The main control chip generates a start signal based on the pressure deviation signal D3 and sends it to the vertical correction mechanism 3. This is equivalent to the control module controlling the vertical correction mechanism 3 to start based on the pressure deviation signal D3 until the pressure deviation signal D3 falls into the preset deviation range value. At this time, the main control chip generates a stop signal and sends it to the vertical correction mechanism 3, so that the vertical correction mechanism 3 maintains its current position, thereby achieving precise correction action. The slide mechanism 2 can maintain a neutral position in the vertical direction.

[0120] It should be explained that by setting two vertical pressure sensing elements 53, it can be ensured that the ram mechanism 2 can capture the pressure deviation signal D3 regardless of whether it deviates upward or downward. It can be understood that the pressure deviation signal D3 can be obtained by subtracting the measured value from the reference value. At this time, a deviation range for reference can be preset in advance. When the deviation value of the pressure deviation signal D3 is within this range, it indicates that the ram mechanism 2 is within a reasonable error range, thereby determining whether the correction action is in place.

[0121] Based on the above configuration, on the one hand, since the vertical pressure sensing element 53 directly abuts against the slide mechanism 2, it can directly detect the offset of the slide mechanism 2 and effectively measure the position error. On the other hand, the vertical pressure sensing element 53 can make reasonable use of the empty space of the lateral correction sleeve 42, resulting in a more compact structure. Furthermore, since the lateral correction mechanism 4 does not have a degree of freedom to swing in the vertical direction, it can also provide a precise positioning reference for the vertical pressure sensing element 53, effectively ensuring that the vertical pressure sensing element 53 obtains accurate measurement values, which further helps to maintain the accuracy of the vertical correction action.

[0122] In other embodiments, the number of lateral pressure sensing elements 54 is also set to two, and the two lateral pressure sensing elements 54 are respectively disposed on the inner walls of the vertical correction sleeve 32 on both sides in the horizontal direction.

[0123] At this time, when the ram mechanism 2 shifts laterally, it squeezes the lateral pressure sensing element 54 and generates a pressure deviation signal D4. The pressure deviation signal D4 from the lateral pressure sensing element 54 is sent to the receiving end of the main control chip. The main control chip generates a start signal based on the pressure deviation signal D4 and sends it to the lateral correction mechanism 4. This is equivalent to the control module controlling the lateral correction mechanism 4 to start based on the pressure deviation signal D4 until the pressure deviation signal D4 falls into the preset deviation range value. At this time, the main control chip generates a stop signal and sends it to the lateral correction mechanism 4, so that the lateral correction mechanism 4 maintains its current position, thereby achieving precise correction action. The ram mechanism 2 can maintain a neutral position in the horizontal direction.

[0124] It should be explained that by setting two lateral pressure sensing elements 54, it can be ensured that the ram mechanism 2 can capture the pressure deviation signal D4 regardless of whether it shifts upward or downward. It can be understood that the pressure deviation signal D4 can be obtained by subtracting the measured value from the reference value. At this time, a deviation range can be preset. When the deviation value of the pressure deviation signal D4 is within this range, it indicates that the ram mechanism 2 is within a reasonable error range, thereby determining whether the correction action is in place.

[0125] Based on the above configuration, on the one hand, since the lateral pressure sensing element 54 directly abuts against the slide mechanism 2, it can directly detect the offset of the slide mechanism 2 and effectively detect measurement errors. On the other hand, the lateral pressure sensing element 54 can make reasonable use of the empty space of the vertical correction sleeve 32, resulting in a more compact structure. Furthermore, since the vertical correction mechanism 3 does not have the freedom to swing on the horizontal plane, it can also provide a precise positioning reference for the lateral pressure sensing element 54, effectively ensuring that the lateral pressure sensing element 54 obtains accurate measurement values, further contributing to maintaining the accuracy of the lateral correction action.

[0126] In summary, there are certain technical difficulties in setting up the lateral pressure sensing element 54 and the vertical pressure sensing element 53. One reason is the lack of installation space. This embodiment cleverly utilizes the structural space and overcomes the problem of insufficient space by installing a vertical pressure sensor in the vertical empty position of the lateral correction sleeve 42 and a lateral pressure sensor in the lateral empty position of the vertical correction sleeve 32. On the other hand, since the slide mechanism 2 is prone to vertical or lateral displacement during operation, the force-bearing position of the lateral pressure sensing element 54 and the vertical pressure sensing element 53 will change, which will further lead to errors in the pressure deviation value.

[0127] Furthermore, both the vertical pressure sensing element 53 and the lateral pressure sensing element 54 include a thin-film sensor 9 and an elastic support 10. The thin-film sensor 9 is disposed on the vertical correction mechanism 3 or the lateral correction mechanism 4. One side of the elastic support 10 is disposed on the thin-film sensor 9, and the other side abuts against the sliding ram mechanism 2. When the sliding ram mechanism 2 deviates, it drives the elastic support 10 to deform and apply elastic force to the thin-film sensor 9.

[0128] Specifically, the elastic support 10 includes a first abutment plate 101, a rebound sponge layer 102, and a second abutment plate 103. The first abutment plate 101 and the second abutment plate 103 are respectively disposed on opposite sides of the rebound sponge layer 102. The second abutment plate 103 is attached to the surface of the thin film sensor 9, and the first abutment plate 101 abuts against the sliding bolster mechanism 2.

[0129] Based on the above configuration, when the ram mechanism 2 deviates, the rebound sponge layer 102 can provide torsional space for the first abutment plate 101, so that the first abutment plate 101 continuously abuts against the ram mechanism 2. At the same time, the rebound sponge layer 102 transmits pressure to the second abutment plate 103. Since the second abutment plate 103 is attached to the surface of the thin film sensor 9, it can evenly transmit pressure to the thin film sensor 9, thereby obtaining an accurate pressure deviation value. The thin film sensor 9 then converts it into a pressure deviation signal D3 or D4, which can significantly reduce pressure measurement error and ultimately effectively improve the accuracy of the correction action.

[0130] Therefore, the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
