Description

Technical Field

[0001] The invention relates to the technical field of limit block processing, in particular to a milling machine for processing a highly flat limit block. Background Art

[0002] Limit blocks are used to limit the relative position between workpieces, so that the workpieces to be limited are fixed or move within a specified range. Limit blocks are widely used in various mechanisms and machines. When limit blocks are produced, milling machines are used to process the workpieces through high-speed rotating milling cutters, and the upper surface of the limit blocks is processed flat, so that the produced limit blocks can improve their positioning accuracy when limiting the position of the workpiece or when installed on a flat mounting surface.

[0003] In the prior art, the surface of the limit block needs to reach a certain flatness after processing. Flatness is a parameter that measures the smoothness or flatness of an object's surface. It reflects the degree of deviation between the object's surface and the absolute horizontal plane during processing or production. After the limit block is processed by a milling machine, in order to detect whether the flatness of the limit block can reach a predetermined value, a worker needs to remove the workpiece clamped on the milling machine, and then turn the measured plane of the limit block upside down on the measuring platform, and then insert a feeler gauge of a specified thickness into the gap between the measuring platform and the limit block to measure whether the flatness of the measured plane of the limit block meets the requirements. Unqualified limit blocks need to be clamped again on the tooling fixture of the milling machine for processing to meet the requirements. This results in the need to repeatedly clamp the processed workpiece, and the detection operation is relatively cumbersome, affecting the production efficiency of the workpiece.

[0004] Application Contents In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the processed workpiece needs to be clamped repeatedly, and the flatness detection operation is relatively cumbersome, which affects the production efficiency of the workpiece.

The translation seat moves horizontally along the tracks arranged on both sides of the processing table. The two translation seats are controlled by a driving mechanism to move synchronously along the corresponding tracks. Both ends of the horizontal axis are fixed with mounting blocks, and a vertical groove is vertically opened on the translation seat. The mounting block moves vertically along the vertical groove on the translation seat. The two translation seats are located at the bottom of the vertical groove and are respectively installed with a distance sensor 1 and a distance sensor 2; An intelligent measurement controller is installed on one side of the processing table.

The flatness detection module is electrically connected to the lateral movement control module and the reminder module respectively, the lateral movement control module is electrically connected to the driving mechanism, and the flatness detection module is also electrically connected to distance sensor 1 and distance sensor 2 respectively.

[0006] The milling machine used for processing the above-mentioned medium and high flatness limit blocks can detect the flatness of the workpiece after processing on the milling machine fixture, and automatically detect the flatness data of the workpiece and judge whether it is qualified, thereby improving the detection efficiency, and being able to process unqualified products in a timely manner, avoiding the need for repeated clamping operations, ensuring the high flatness of the limit blocks after milling machine processing, and improving the limit block processing efficiency.

[0007] As a further improvement of the present application, the driving mechanism includes a driving motor 1 and two translation screws threadedly connected to the corresponding translation seats. The output end of the driving motor 1 drives the two translation screws to rotate synchronously through a gear set. The translation screw is electrically connected to the transverse movement control module, and the transverse movement control module is electrically connected to a driving control button.

[0008] As a further improvement of the present application, an infrared sensor 1 is installed on the translation seat, and the infrared sensor 1 includes a signal sending component and a signal receiving component. The signal sending component of the infrared sensor 1 is installed on one of the translation seats, and the signal receiving component of the infrared sensor 1 is installed at a corresponding position of the other translation seat. The infrared sensor 1 and the flatness detection module are electrically connected.

[0009] As a further improvement of the present application, a positioning seat is installed on one side of each translation seat close to the middle of the processing table, and an infrared sensor is installed on the positioning seat.

[0010] As a further improvement of the present application, a gas cavity is opened in the middle of the translation seat, and the vertical groove is connected with the inner cavity of the gas cavity through an air outlet opened on the side wall of the translation seat. The gas cavity is connected to the output end of the air pump assembly through a pipeline, and the air pump assembly is electrically connected to the flatness detection module.

[0011] As a further improvement of the present application, the mounting block is a square structure, and the outer surface of the mounting block is smoothed.

[0012] As another improvement of the present application, it also includes a measuring and positioning component, which includes an adjustment frame axially slidably connected to the processing table along the horizontal axis, and drive motor 2, and the output end of drive motor 2 is equipped with a screw threadedly connected to the adjustment frame.

An infrared sensor 2 is installed on the side of the adjustment frame facing the middle of the processing table, and the infrared sensor 2 is electrically connected to the workpiece positioning module.

[0014] To sum up, through the joint detection of the lateral control module, the flatness detection module and the flatness detection component on the intelligent measurement controller, the flatness detection can be performed on the workpiece after processing on the milling machine fixture, and the flatness data of the workpiece can be automatically detected to determine whether it is qualified, and reminders can be issued for unqualified products to remind the operator to deal with them, thereby improving the detection efficiency, and unqualified products can be processed in time, avoiding the need for repeated clamping operations, and ensuring that the limit block after milling machine processing is highly flat, which not only improves the detection efficiency, but also greatly improves the intelligence and automation of the detection process, so that during the milling machine processing, a highly flat limit block product can be obtained.

[0017] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0018] The first implementation method: Figure 1-Figure 6 A milling machine for processing a high-flat limit block is shown. The milling head assembly 2 is installed on a processing table 1 and is used to process a workpiece 3 clamped on a fixture; the flatness detection assembly includes a translation seat 8 arranged in parallel on both sides of the processing table 1, a horizontal axis 6 installed between the two translation seats 8, and a measuring cylinder 7 sleeved on the horizontal axis 6. The translation seat 8 moves horizontally along the track 18 arranged on both sides of the processing table 1, and the two translation seats 8 are controlled by a driving mechanism to move synchronously along the corresponding track 18. Both ends of the horizontal axis 6 are fixed with mounting blocks 13, vertical grooves 9 vertically opened on the translation seat 8, and the mounting blocks 13 move vertically along the vertical grooves 9 on the translation seat 8. The two translation seats 8 are located at the bottom of the vertical grooves 9 and are respectively installed with distance sensors 10 and 11. After the milling head assembly 2 on the processing table 1 processes the surface of the workpiece 3, it is necessary at this time The flatness of the upper surface of the workpiece 3 is detected, and the translation seats 8 on both sides are driven by the driving mechanism to move horizontally along the track 18. The horizontal track 18 will drive the horizontal axis 6 and the measuring cylinder 7 to move toward the workpiece 3. Since the mounting blocks 13 at both ends of the horizontal axis 6 are in the vertical grooves 9, the horizontal axis 6 and the mounting blocks 13 are not affected by external forces in the vertical direction. Therefore, when the translation seat 8 drives the horizontal axis 6 to move continuously, the measuring cylinder 7 will move to the upper surface of the workpiece 3 (i.e., the surface to be detected), and will roll or translate along the upper surface of the workpiece 3 under the driving action of the horizontal axis 6. The surface flatness of the workpiece 3 can be judged by the movement state of the measuring cylinder 7 on the surface of the workpiece 3, and the distance to the mounting blocks 13 at both ends of the horizontal axis 6 is detected in real time by the distance sensor 10 and the distance sensor 2 11, so as to obtain the movement state of the measuring cylinder 7 along the upper surface of the workpiece 3.

[0019] Furthermore, by configuring the measuring cylinder 7 to be a cylindrical structure, when the measuring cylinder 7 approaches and contacts the workpiece 3, the horizontal axis 6 continuously drives the measuring cylinder 7 to move horizontally, and the cylindrical measuring cylinder 7 can smoothly roll to the upper surface of the workpiece 3. At this time, the measuring cylinder 7 and the horizontal axis 6 are lifted up by the workpiece 3, so that the mounting blocks 13 at both ends of the horizontal axis 6 are not subjected to external force in the vertical direction, and the measuring cylinder 7 can roll or slide freely along the surface contour of the workpiece 3.

[0020] In addition, an intelligent measurement controller 4 is installed on one side of the processing table 1. The intelligent measurement controller 4 is provided with a lateral movement control module, a flatness detection module, and a reminder module 5. The flatness detection module is electrically connected to the lateral movement control module and the reminder module 5, respectively. The lateral movement control module is electrically connected to the driving mechanism. The flatness detection module is also electrically connected to the distance sensor 10 and the distance sensor 2 11, respectively. The flatness detection module presets qualified data of the surface flatness of the workpiece 3, that is, qualified data of the distance difference between the highest point and the lowest point when the measuring tube 7 rolls on the surface of the workpiece 3.

[0021] See also Figure 1-Figure 6When the flatness of the surface of the workpiece 3 processed by the milling machine is detected, the lateral movement control module sends a driving signal to the driving mechanism, and the driving mechanism drives the two translation seats 8 to move horizontally along the track 18. At this time, the translation seat 8 drives the mounting block 13 to move horizontally, and synchronously drives the horizontal axis 6 and the measuring cylinder 7 to move toward the workpiece 3; when the lateral movement control module sends a driving signal to the driving mechanism, the lateral movement control module will send a detection signal to the flatness detection module. At this time, the distance sensor 10 and the distance sensor 2 11 installed at the bottom of the vertical slot 9 will detect the distance data between them and the top mounting block 13 in real time, and send the distance data to the flatness detection module (when the measuring cylinder 7 moves toward the workpiece). During the movement of the workpiece 3, the measuring cylinder 7 is not subjected to external forces in the vertical direction, and the value change of its distance data is zero). When the measuring cylinder 7 abuts against one side of the workpiece 3 and rolls onto the workpiece 3, the distance sensor 1 10 and the distance sensor 2 11 will detect the change of the distance data between them and the top mounting block 13 in real time, and continuously transmit the changed distance data to the flatness detection module. The flatness detection module calculates the average value of the distance data received from the distance sensor 1 10 and the distance sensor 2 11, and calculates the distance difference between the maximum value and the minimum value in the average value, and compares the distance difference value with the qualified data of the surface flatness of the workpiece 3 preset in the flatness detection module. The distance difference is compared to determine whether it exceeds the preset qualified data. If the judgment result is no, the surface balance of the workpiece 3 is qualified. In this process, when the measuring cylinder 7 continues to roll along the surface of the workpiece 3 until it is separated from the surface of the workpiece 3, the measuring cylinder 7 is not supported by the workpiece 3 and restores the initial height. At this time, the distance data sent by the distance sensor 1 10 and the distance sensor 2 11 received by the flatness detection module are the same as the distance data of the initial state. The flatness detection module sends a reset signal to the lateral movement control module. After receiving the reset signal, the lateral movement control module controls the driving mechanism to reversely control the translation seat 8 to reset; when the judgment result is yes, the surface balance of the workpiece 3 is unqualified. At this time, the flatness The flatness detection module will send a reminder signal to the reminder module 5, and the reminder module 5 will emit light or sound to remind that the product is unqualified, and remind the operator to deal with it. At the same time, the flatness detection module sends a reset signal to the lateral movement control module. After receiving the reset signal, the lateral movement control module controls the driving mechanism to reversely control the translation seat 8 to reset; it can perform flatness detection on the workpiece 3 processed on the milling machine fixture, and automatically detect the flatness data of the workpiece 3 to determine whether it is qualified, thereby improving the detection efficiency, and can promptly process unqualified products, avoiding the need for repeated clamping operations, ensuring the high flatness of the limit block after milling machine processing, and improving the limit block processing efficiency.

[0022] Also, see Figure 2-Figure 3The driving mechanism includes a driving motor 17 and two translation screws 12 threadedly connected to the corresponding translation seats 8. The output end of the driving motor 17 drives the two translation screws 12 to rotate synchronously through a gear set. The translation screw 12 is electrically connected to the transverse movement control module, and the transverse movement control module is electrically connected to a driving control button. The driving motor 17 can synchronously drive the two translation screws 12 to rotate using the gear set, thereby controlling the two corresponding translation seats 8 to reciprocate synchronously by controlling the two translation screws 12 to rotate synchronously forward or reverse.

[0023] Moreover, when the flatness of the surface of the workpiece 3 is detected, the operation can be performed by pressing the drive control button. At this time, the drive control button sends a drive signal to the transverse movement control module. After receiving the drive signal, the transverse movement control module controls the drive motor 17 to work, thereby controlling the two translation seats 8 to move synchronously.

[0024] It is worth mentioning that see Figure 4 , Figure 5 and Figure 7 An infrared sensor 14 is installed on the translation seat 8. The infrared sensor 14 includes a signal sending component and a signal receiving component. The signal sending component of the infrared sensor 14 is installed on one of the translation seats 8, and the signal receiving component of the infrared sensor 14 is installed at the corresponding position of the other translation seat 8. The infrared sensor 14 is electrically connected to the flatness detection module. By installing the infrared sensor 14 on the translation seat 8, the infrared sensor 14 can be used to detect in real time whether the translation seat 8 moves to the same straight line as the workpiece 3, and at the same time determine whether the measuring tube 7 is in contact with the workpiece 3. The workpiece 3 can block the data transmission between the signal sending component and the signal receiving component on the infrared sensor 14, and determine whether the translation seat 8 that moves synchronously with the infrared sensor 14 moves to the same straight line as the workpiece 3.

[0025] When the flatness of the surface of the workpiece 3 is detected, during the movement of the translation seat 8 toward the workpiece 3, when the infrared sensor 14 detects that the translation seat 8 has not reached the workpiece 3, the infrared sensor 14 sends a detection signal to the flatness detection module, and the flatness detection module does not calculate and process the distance data received from the distance sensor 10 and the distance sensor 2 11; when the infrared sensor 14 detects that the translation seat 8 has reached the workpiece 3, the measuring tube 7 is in contact with the surface of the workpiece 3 and is supported, and the infrared sensor 14 sends a corresponding detection signal to the flatness detection module, and the flatness detection module calculates and processes the distance data received from the distance sensor 10 and the distance sensor 2 11, and at the same time compares the distance difference with the qualified data of the surface flatness of the workpiece 3 preset in the flatness detection module; by setting the infrared sensor 14 It can reduce the data processing amount of the flatness detection module, and can accurately determine whether the measuring tube 7 is in contact with the workpiece 3, so that the flatness detection module can quickly process the distance data of the distance sensor 10 and the distance sensor 2 11 when the measuring tube 7 is in contact with the workpiece 3, thereby improving the data processing capability of the flatness detection module; and the infrared sensor 14 is continuously driven to move by the translation seat 8. When the infrared sensor 14 detects that the translation seat 8 and the workpiece 3 are not in the same straight line, that is, the measuring tube 7 is separated from the surface of the workpiece 3, the infrared sensor 14 sends a detection end signal to the flatness detection module, and at the same time, the flatness detection module sends a reset signal to the lateral movement control module. After receiving the reset signal, the lateral movement control module controls the driving mechanism to reversely control the translation seat 8 to reset, so that the equipment can be accurately controlled to perform flatness detection on the workpiece 3, and the equipment after detection can be reset in time.

[0026] Also, see Figure 4-Figure 5 A positioning seat 15 is installed on one side of each translation seat 8 close to the middle of the processing table 1, and the infrared sensor 14 is installed on the positioning seat 15. By installing the positioning seat 15, the position of the lowest end of the horizontal axis 6 can be limited to prevent the measuring cylinder 7 from being unable to roll smoothly to the upper surface of the workpiece 3 when the horizontal axis 6 drives the measuring cylinder 7 to move to the workpiece 3. The installation height of the positioning seat 15 can be adjusted according to the top height of the workpiece 3 to meet different workpiece 3 detection requirements.

[0027] In this implementation, see Figure 6-Figure 7A gas chamber 16 is provided in the middle of the translation seat 8, and the vertical slot 9 is connected to the inner cavity of the gas chamber 16 through an air outlet 22 provided on the side wall of the translation seat 8. The gas chamber 16 is connected to the output end of the air pump assembly through a pipeline, and the air pump assembly is electrically connected to the flatness detection module. When the flatness detection module receives the detection signal sent by the lateral movement control module, the flatness detection module will simultaneously send a working signal to the air pump assembly. At this time, the output end of the air pump assembly is inflated toward the inner cavity of the gas chamber 16 through the pipeline, and the gas chamber 16 is inflated. The gas in 6 will be discharged through the air outlet 22, which will form an air cushion layer between the two sides of the mounting block 13 and the side walls of the vertical groove 9, thereby reducing the friction between the two side walls of the mounting block 13 and the two sides of the vertical groove 9, reducing the influence of the two side walls of the vertical groove 9 on the movement of the mounting block 13 in the vertical direction, and improving the balance detection accuracy; after the detection is completed, when the flatness detection module sends a reset signal to the lateral movement control module, the flatness detection module will synchronously send a stop working signal to the air pump assembly, and the air pump assembly will stop working.

[0028] Preferably, the mounting block 13 is a square structure, and the outer surface of the mounting block 13 is smoothed, so that the mounting block 13 can better move along the vertical groove 9 in the vertical direction and reduce the friction between the mounting block 13 and the side wall of the vertical groove 9.

[0029] The second implementation method: Figure 8-Figure 9 As shown, unlike the first embodiment, it also includes a measuring and positioning component, which includes an adjusting frame 20 slidably connected to the processing table 1 along the axial direction of the horizontal axis 6, and a driving motor 19. The output end of the driving motor 19 is equipped with a screw threadedly connected to the adjusting frame 20. When the translation seat 8, the horizontal axis 6 and the measuring cylinder 7 are in the initial position, the measuring cylinder 7 is between the frames of the adjusting frame 20. The driving motor 19 controls the forward and reverse rotation of the screw to control the movement of the adjusting frame 20. The adjusting frame 20 can control the measuring cylinder 7 to adjust its position on the horizontal axis 6, so that the moving trajectory of the measuring cylinder 7 during detection can cover the workpiece 3, so that the measuring cylinder 7 can be smoothly moved to the upper surface of the workpiece 3.

[0030] Also, see Fig.10The intelligent measurement controller 4 is also provided with a workpiece positioning module, which is electrically connected to the traverse control module and the drive motor 19 respectively. An infrared sensor 21 is installed on the side of the adjustment frame 20 facing the middle of the processing table 1. The infrared sensor 21 is installed with a signal sending component and a signal receiving component, that is, it can send infrared signals and receive infrared signals. The infrared sensor 21 can detect whether the adjustment frame 20 moves to the position corresponding to the workpiece 3. The infrared sensor 21 is electrically connected to the workpiece positioning module. When the flatness of the surface of the workpiece 3 processed by the milling machine is detected, the traverse control module sends a positioning signal to the workpiece positioning module. After receiving the positioning signal, the workpiece positioning module sends a working signal to the drive motor 19, and the drive motor 19 drives The adjusting frame 20 and the infrared sensor 21 move synchronously. When the infrared sensor 21 detects the position corresponding to the workpiece 3, it sends the detection signal to the workpiece positioning module. At this time, the adjusting frame 20 and the measuring tube 7 are also in the corresponding positions with the workpiece 3. After receiving the detection signal from the infrared sensor 21, the workpiece positioning module sends an acceptable lateral movement control signal to the lateral movement control module. After receiving the acceptable lateral movement control signal, the lateral movement control module sends a driving signal to the driving mechanism to perform subsequent detection work. Through the above-mentioned structural design, the position of the workpiece 3 can be automatically determined and the measuring tube 7 can be moved to the corresponding position, which not only improves the detection efficiency, but also greatly improves the intelligence and automation of the detection process, so that a high-flat limit block product can be obtained during the milling machine processing.

[0031] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
