Through the compilation of an automatic control program, it automatically operates, automatically detects, and judges the technological parameters required for post-welding leveling of turnout sleepers; when the measured value after leveling the turnout sleeper meets the product process requirements, the system automatically stores the parameters at the time of passing the re-inspection into the holding memory, thereby generating the automatically adjustable post-welding technological parameters for turnout sleepers that can be repeatedly called, simplifying and realizing the efficient operation of the automatically adjustable post-welding control system for different types of turnout sleepers, effectively targeting different types of turnout sleepers, improving the operation efficiency of this automatic leveling, and improving the production efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying Figures 1-5 , and it is obvious that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] (such as Figure 1Automatic generation method for post-welding leveling process parameters of turnout tie plates, including the following steps:

[0033] Step S001: Manually input the length, width, and thickness dimension parameter information of the turnout tie plate into the industrial computer control system 1 to determine the size model of the turnout tie plate, so as to automatically generate corresponding turnout tie plates of different models for subsequent processes. The industrial computer control system 1 transmits the length, width, and thickness dimension parameter information of the turnout tie plate to the PLC controller 2.

[0034] Step S002: The PLC controller 2 generates corresponding control instructions after calculating based on the length, width, and thickness dimension parameter information of the turnout tie plate, and transmits the control instructions to the press control unit 3. The press control unit 3 controls the automatic leveling press 31 to stop when the center of the press is moved directly above the turnout tie plate according to the length and width parameter information of the turnout tie plate. After moving in place, the press control unit 3 stores the position parameter data information of the automatic leveling press 31 when it stops in the PLC controller 2, so as to realize the in-place movement function of the automatic leveling press 31 directly above the center of different turnout tie plates for different turnout tie plate models.

[0035] Step S003: Multiple measuring devices 41 in the measurement control unit 4 conduct on-line detection of the turnout tie plate and transmit the detection results to the PLC controller 2. The measuring device 41 is six linear displacement sensors.

[0036] Step S004: The PLC controller 2 performs arithmetic comparison based on the detection results transmitted by the measuring device 41. Compare the difference between the detection results of every two measuring devices 41, and find the position of the measuring device 41 with the largest difference, indicating that the turnout tie plate point above the measuring device 41 at this point is the relative highest convex point, so as to determine its position for adjusting the translation and downward pressure position of the pressing block.

[0037] Step S005: If the result after the arithmetic comparison by the PLC controller 2 is outside the process requirement range, that is, if the difference is greater than 1 mm, it means that the flatness does not meet the requirements. At this time, the PLC controller 2 outputs a control instruction to the press control unit 3 according to the comparison result. The press control unit 3 controls the automatic leveling press 31 to adjust the left and right translation position of the pressing block and the downward pressure stroke of the pressing block according to the control instruction. The left and right translation position of the pressing block needs to adjust the pressing block directly above the turnout tie plate of the measuring device 41 with the largest difference. The downward pressure stroke of the pressing block only needs to be 0.02 mm more than the previous downward pressure stroke. After the left and right translation of the pressing block is in place, the press control unit 3 modifies the limit of the downward pressure stroke of the automatic leveling press 31 by multiple fixed-value accumulations according to the comparison result, that is, the downward pressure stroke of the pressing block is 0.02 mm more than the previous downward pressure stroke each time, and this fixed value is accumulated and modified. Through the automatic leveling press 31, the turnout tie plate is pressed and leveled by multiple fixed-value accumulations.

[0038] Step S006. Since the briquette will rebound and reset, steps S003, S004, and S005 are repeated until the result after the PLC controller 2 performs arithmetic comparison is within the process requirements, that is, the difference between any two measuring devices is ≤ 1 mm. Then, the automatic leveling press 31 stops pressing for leveling, and the flatness meets the requirements.

[0039] Step S007. The PLC controller 2 outputs a control instruction to control the automatic leveling press 31 to return and reset. The PLC controller 2 automatically stores all process parameters after automatic leveling and transfers all the process parameters after leveling to the holding memory of the industrial computer control system 1 for storage. So that when the turnout tie plate of the same model is used next time, it can still be leveled according to the leveling operation sequence and method corresponding to the turnout tie plate, realizing the batch leveling operation of the turnout tie plate of this model. By using a holding memory, the stored data will not be lost due to a short power outage of the system, ensuring the reliability of data storage.

[0040] Step S008. The industrial computer control system 1 generates a post-welding leveling process for the turnout tie plate that can be repeatedly called. So that when the turnout tie plate of the same model is used next time, fast and efficient automatic leveling operations can be realized, eliminating the need for multiple re-inspection processes and improving the leveling efficiency.

[0041] (As Figure 2 , Figure 3 shown) The automatic generation system for post-welding leveling process parameters of the turnout tie plate includes the industrial computer control system 1, and the industrial computer control system 1 has a holding memory; the industrial computer control system 1 is communicatively connected and exchanges data with the PLC controller 2 through a Profinet bus; the press control unit 3 and the measurement control unit 4 are communicatively connected to the PLC controller 2 through a Profinet bus to form a computer network and realize logical control and judgment.

[0042] The measurement control unit is connected to the input end of the PLC controller. The output end of the PLC controller is connected to the input end of the press control unit. The press control unit feeds back its real-time position to the PLC controller, that is, the press control unit and the PLC controller are communicatively connected interactively. (Combined with Figure 3 )

[0043] Communication connection is carried out using a Profinet bus. Among them, Profinet is a real-time technology specification running on industrial Ethernet. The full name of Profinet is Process Field Net. It is launched by the PROFIBUS International Organization (PROFIBUS International, PI) and is an automation bus standard based on industrial Ethernet technology. PROFINET provides a complete network solution for the field of automation communication.

[0044] PROFINET has the communication ability between multi-manufacturer products, automation and engineering modes, and is optimized for distributed intelligent automation systems. Its application results can greatly save configuration and commissioning costs. The PROFINET system can integrate other bus systems including Profibus, and at the same time provides protection for existing systems.

[0045] (such as Figure 4 , Figure 5 ) In the above embodiments, further: the press control unit 3 has an automatic leveling press 31; the automatic leveling press 31 is installed with a measurement control unit 4; the measurement control unit 4 has a plurality of measurement devices 41, and the measurement device 41 is a displacement sensor. Among them, the measurement control unit 4 is connected to the input end of the PLC controller, and the output end of the PLC controller is connected to the input end of the press control unit 3 (in combination with Figure 3 ).

[0046] In the above embodiments, further: the automatic leveling press 31 includes a base 311, and the base is a horizontal base, which provides a horizontal support surface for the installation of the measurement device, the top block, the first and second support plates.

[0047] A vertical top block 312 is installed at the center of the upper end surface of the base 311, and the top block is used to horizontally support and position the bottom end of the turnout tie plate.

[0048] On the left and right sides of the top block 312, there are respectively axially symmetrically liftable first support plates 313 and second support plates 314; the first support plate and the second support plate are driven to lift by a first cylinder or hydraulic cylinder and a second cylinder or hydraulic cylinder.

[0049] In the above embodiments, further: the first support plate 313 and the second support plate 314 are driven to lift by the first and second cylinders or hydraulic cylinders; the up and down movement system of the pressing block includes a vertically arranged hydraulic cylinder or cylinder, and the execution end of the piston rod of the hydraulic cylinder or cylinder is fixedly connected to the top end of the pressing block device mounting seat 315 to drive the overall lifting movement of the pressing block device mounting seat 315.

[0050] On the left and right sides of the top block 312, there are six vertically upward measurement devices 41; the measurement devices 41 are arranged axially symmetrically left and right with the top block 312 as the axis of symmetry. The measurement device is used for multi-point detection of the flatness of the turnout tie plate. The number of measurement devices can be adaptively increased or decreased according to the size of the workpiece to be leveled. The measurement device can be one of a fiber optic sensor, a linear displacement sensor, and a ranging sensor. Preferably, it is a linear displacement sensor. The measurement device 55 is arranged axially symmetrically left and right with the top block 52 as the axis of symmetry.

[0051] The linear displacement sensor has an automatic telescopic mechanism, and the linear displacement sensor is installed at the telescopic top end of the automatic telescopic mechanism. The automatic telescopic mechanism is composed of a sleeve, a sleeve slide rod, and a spring. The sleeve slide rod is slidably and fittingly installed in the sleeve, and a spring is coaxially installed between the bottom end of the sleeve slide rod and the inner side wall of the bottom end of the sleeve. The top end of the sleeve slide rod is fixedly connected to the linear displacement sensor. The measuring device, that is, the linear displacement sensor, is supported and installed by the automatic telescopic mechanism, which can effectively protect the detection end of the sensor and prevent the occurrence of damage to the detection end. Moreover, after the pressing block is lifted, the linear displacement sensor can automatically rebound and reset under the restoring elastic force of the compressed spring.

[0052] Specifically: the six measuring devices are respectively arranged symmetrically left and right with the top block as the axis of symmetry; that is, three measuring devices are respectively arranged on the left and right sides of the top block. Among the three measuring devices on each side, one measuring device is arranged outside the first support plate or the second support plate, and the other two measuring devices are arranged inside the first support plate or the second support plate.

[0053] Above the base 311, there is a pressing block device mounting seat 315; the top end of the pressing block device mounting seat 315 is fixedly connected to the execution end at the bottom of the pressing block up and down movement system. The pressing block up and down movement system includes a vertically arranged hydraulic cylinder or air cylinder, and the execution end of the piston rod of the hydraulic cylinder or air cylinder is fixedly connected to the top end of the pressing block device mounting seat to drive the overall lifting and moving of the pressing block device mounting seat.

[0054] The pressing block device mounting seat 315 supports and installs a left pressing block horizontal movement device 316 and a right pressing block horizontal movement device 317; the left pressing block horizontal movement device and the right pressing block horizontal movement device adjust their lifting and displacement together with the pressing block device mounting seat.

[0055] The left pressing block horizontal movement device 316 and the right pressing block horizontal movement device 317 respectively adjust the translation positions of the vertically downward left pressing block 318 and right pressing block 319.

[0056] In the above embodiment, further: the left pressing block horizontal movement device 316 and the right pressing block horizontal movement device 317 respectively include a servo motor 3171, and the servo motor 3171 is connected to and drives the horizontal lead screw 3172 to rotate. The servo motor is connected to and drives the horizontal lead screw to rotate. The left and right sides of the rod body of the horizontal lead screw are respectively rotationally supported and installed through a pair of left and right bearing seat assemblies, and are rotationally supported and installed at the bottom of the pressing block device mounting seat with the pressing block device mounting seat as the support through the bearing seat assembly.

[0057] The horizontal lead screw 3172 is threadedly and fittingly installed with a lead screw nut 3173. The lead screw nut 3173 is connected to the top end of the vertically installed pressing block through a bearing seat assembly 3174. The pressing block is driven by a servo motor 3175 to adjust the translation position of the left pressing block 318 or the right pressing block 319 relative to the horizontal lead screw 3172.

[0058] To adjust the horizontal position of the pressing block by driving the pressing block through a lead screw nut: The inner ring of a bearing is coaxially sleeved outside the lead screw nut, the outer ring of the bearing is fixedly installed in a bearing seat, and the bearing seat is integrally fixed to the top of the pressing block, so as to realize the function of adjusting the left - right displacement of the vertical pressing block driven by the horizontally translatable and rotatable lead screw nut.

[0059] When the servo - motor is installed vertically downward as shown in the figure, the power output shaft of the servo - motor is installed with a driving bevel gear in a right - angle transmission structure. The driving bevel gear meshes with a driven bevel gear, and the driven bevel gear is coaxially installed at the end of a horizontal lead screw. The servo - motor drives the horizontal lead screw to rotate through the right - angle transmission.

[0060] In addition to the above - mentioned embodiments: The power output shaft of the servo - motor can also be coaxially and fixedly installed with the horizontal lead screw. The power output shaft of the servo - motor is coaxially and fixedly connected to the outer end of the horizontal lead screw through a coupling, so as to drive the horizontal lead screw to rotate through the servo - motor.

[0061] The present invention adopts the downward pressing operations of the left and right pressing blocks, and uses the first and second supporting plates and the central top block to cooperate with each other to realize the lifting and pressing operation of the switch tie plate. The combination of pressing and jacking is adopted. The left and right pressing blocks that can translate left and right are used to perform fine - motion downward pressing and straightening adjustment on the convex position of the switch tie plate, meeting the requirements of high - precision and high - efficiency leveling.

[0062] The automatic leveling detection principle of the automatic leveling press 31 is as follows: Before detection, the PLC controller controls the first pallet and the second pallet to rise horizontally and coplanarly and be higher than the upper end face of the top block; the turnout tie plate is placed on the central positions of the first pallet and the second pallet; six detection devices conduct an initial detection on the turnout tie plate and transmit the detection data to the PLC controller; the PLC controller adjusts the horizontal downward position of the pressing block through the pressing block horizontal movement device according to the detection result, so that the pressing block moves directly above the turnout tie plate with the maximum value detected by the six detection devices, and the PLC controller controls the pressing block to move downward through the pressing block up and down movement system and contact with the turnout tie plate. The first pallet and the second pallet are pressed downward, and the six detection devices change at the same rate; the back of the turnout tie plate contacts the top block, and the pressing block continues to press down the turnout tie plate. The change rate and displacement of the six detection devices change, and the real-time detection data is transmitted to the PLC controller; the PLC controller calculates the difference between the maximum value and the minimum value of the displacement of the six detection devices. When the difference is greater than 1 mm, the PLC controller adjusts the horizontal movement of the moving pressing block through the pressing block horizontal movement device to move directly above the turnout tie plate where the detection device with the maximum difference is located. The PLC controller controls the pressing block to press down again through the pressing block up and down movement system, and the value of the pressing block pressing down again is 0.2 mm more than the last pressing down value. After the pressing block presses down again, the six detection devices detect the turnout tie plate again. If the difference between the maximum value and the minimum value of the displacement of the six detection devices is still greater than 1 mm, the PLC controller adjusts the pressing block to press down again until the difference between the maximum value and the minimum value of the displacement detected by the six detection devices is less than or equal to 1 mm.

[0063] The measurement device in the automatic leveling press is connected to the input end of the PLC controller, and the measurement device collects the flatness data information in real time. The PLC controller has a measurement device signal conversion and processing device, and the measurement device signal conversion and processing device is an A / D converter for converting the analog quantity and digital quantity of the measurement device. The PLC controller calculates according to the data detected by the measurement device and calculates the difference of the six measurement devices. If the difference > 1 mm, it proves that the flatness is unqualified; then the PLC controller outputs a control instruction to control the pressing block to move directly above the measurement device with the maximum difference and press down again for leveling adjustment. The stroke displacement of the pressing down again for leveling adjustment is 0.2 mm more than the last pressing down value. If the difference ≤ 1 mm, it proves that the flatness is qualified and the pressing down for leveling is stopped.

[0064] When pressing down for leveling: The output end of the PLC controller is connected to the lifting control ends of the first pallet and the second pallet; the PLC controller forms a control instruction according to the calculated detection difference value, and controls the adjusted heights of the first pallet and the second pallet through the control instruction. At the same time, the output end of the PLC controller is connected to the control input ends of the left press block horizontal movement device and the right press block horizontal movement device; the PLC controller forms a control instruction according to the detection difference value, and controls the left and right translation positions of the left press block and the right press block by adjusting the left press block horizontal movement device and the right press block horizontal movement device through the control instruction. Moreover, the PLC controller is interconnected with the up and down movement system of the press block. The PLC controller forms a control instruction according to the detection difference value, and controls the stroke of the piston rod of the up and down movement system to move up and down through the control instruction, so that the stroke displacement of the next pressing and leveling adjustment is increased by 0.2 mm compared with the previous pressing value, and the automatic leveling and automatic detection are realized reciprocally until the process requirements are met.

[0065] In summary, the present invention adopts a system for automatically generating post-welding leveling process parameters of turnout tie plates to automatically generate corresponding leveling processes for different turnout tie plates, simplifies and realizes the efficient operation of the post-welding automatic leveling control system for different types of turnout tie plates for the post-welding automatic leveling process of different types of turnout tie plates, effectively improves the operation efficiency of automatic leveling, and improves the production efficiency.
