Description

Technical Field

[0001] This utility model relates to the field of trimming technology, specifically a trimming device for precision casting parts processing. Background Technology

[0002] Stainless steel, carbon steel, and alloy steel can all be processed into castings in the form of plates. When the plate castings are cut into the required rectangular shape, the cut edges may have burrs or be uneven, affecting the appearance quality of the plate. Therefore, a trimming device is needed.

[0003] A Chinese patent with authorization announcement number CN219725389U discloses a trimming device for casting thin-walled parts, including a base, a column mounted on the top of the base, a top plate mounted on the top of the column, a servo motor mounted on the top plate, a power output shaft at the bottom of the servo motor passing through the top plate and fixedly mounted on a tool holder, a trimming knife fixedly connected to the bottom of the tool holder, a limit groove formed on the top surface of the base, a limit block slidably arranged in the limit groove, a vacuum suction cup mounted on the top of the limit block, a vacuum pump mounted at one end of the top of the base, and the suction end of the vacuum pump connected to the vacuum suction cup through a hose; when fixing thin-walled parts, there is no need to use a clamping and fixing mechanism, which can effectively avoid deformation of thin-walled parts due to clamping. The thin-walled parts are fixed by the vacuum suction cup, which is more convenient to operate, can improve processing efficiency, and is suitable for widespread promotion and use.

[0004] However, the above-mentioned trimming device still has some problems. In practical applications, there is no mechanism to determine the contact between the trimming roller and the casting in time, which requires additional time to adjust the position of the trimming roller, reducing the processing efficiency of the casting. In addition, the trimming motor will turn on before the trimming roller has made proper contact with the casting, resulting in energy waste. Therefore, a trimming device for precision casting is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a trimming device for precision casting parts processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A trimming device for precision casting processing, comprising a worktable, two mounting seats mounted on the top of the worktable, rectangular grooves formed on both sides of each mounting seat, a support rod fixedly connected between the two sides of each rectangular groove, a slider slidably mounted on the outer side of each support rod, the slider being slidably mounted on the inner wall of the rectangular groove, a tension spring fixedly connected between the slider and the rectangular groove, the tension spring being sleeved on the outer side of the support rod, wherein a trigger switch is installed on one side of one of the sliders inside each mounting seat. The system comprises a clamping plate installed on one side of one of the rectangular slots inside each mounting base. The clamping plate and the trigger switch are on the same horizontal line. A connecting shaft is rotatably mounted between two sliders inside each mounting base. A trimming roller is installed on the outside of the connecting shaft. A trimming motor is installed on one side of each slider. One end of the connecting shaft is connected to the output end of the trimming motor. When the trimming roller contacts the side of the casting, it squeezes the slider to move and triggers the switch, thereby starting the trimming motor to perform trimming operations. This achieves rapid response and precise trimming, improves processing efficiency, and reduces energy waste.

[0007] Preferably, servo motors are installed on both sides of the worktable, and threaded rods are installed at the output ends of the servo motors. Slide grooves are opened at both ends of the worktable, and sliding blocks are slidably installed inside the slide grooves. Screw holes are opened inside the sliding blocks, and one end of the threaded rod passes through the screw hole and is rotatably installed inside one side of the slide groove. A telescopic rod is installed on the top side of the sliding block, and an action rod is installed at the working end of the telescopic rod. The mounting bases are respectively installed on the top of the action rods. The precise control of the servo motors enables the trimming roller to accurately align with the side of the casting for trimming operations. The telescopic rod and the action rod further assist in the vertical position adjustment of the mounting bases to adapt to trimming operations of castings of different thicknesses.

[0008] Preferably, the middle of the worktable has an installation groove, and a drive motor is installed inside the installation groove. The driving end of the drive motor is equipped with a rotating shaft, which passes through the installation groove and extends movably to the top of the worktable to install a support plate. The use of the drive motor allows the casting to be easily rotated to the required angle, which facilitates the trimming of the other two sides, improving processing efficiency and quality.

[0009] Preferably, a positioning rod is installed on the outer side of the middle end of the rotating shaft, and a scale is installed on the top side of the worktable outside the rotating shaft. The scale is arc-shaped, and support plates are installed at both ends of the top side of the scale. A pressure sensor is installed on one side of the support plate, and the arc between the pressure sensors is 90 degrees. The pressure sensor is used to monitor the pressure of the positioning rod on the support plate, ensuring the accuracy of the angle adjustment of the casting and avoiding uneven trimming caused by angle deviation.

[0010] Preferably, a fixed frame is installed on the top side of the workbench, a cylinder is installed on the top side of the fixed frame, a rotating shaft is rotatably installed on the working end of the cylinder, a pressing plate is installed on the bottom side of the rotating shaft, and the pressing plate is located directly above the support plate. The cylinder drives the pressing plate to press the casting, ensuring stability during the trimming process and preventing the casting from affecting the trimming quality due to shaking.

[0011] Preferably, a control panel is installed on one side of the workbench. The control panel is electrically connected to the trigger switch, the trimming motor, the pressure sensor, and the drive motor. The control panel is used for signal transmission to the trigger switch and the pressure sensor. The control panel controls the start-up of the trimming motor through the trigger switch and the shut-off of the drive motor through the pressure sensor. The shut-off of the trimming motor and the start-up of the drive motor are both directly controlled by the control panel, which improves the automation and intelligence of the processing.

[0012] The advantages of this utility model are:

[0013] 1. When the trimming roller of this utility model contacts the side of the casting, the trimming roller is subjected to the reaction force of the casting, which will squeeze the slider to move along the support rod in the rectangular groove. At this time, the tension spring between the slider and the rectangular groove is stretched, and the slider of the trigger switch gradually approaches the extrusion plate until the trigger switch is triggered by the extrusion plate. The signal is transmitted to the control panel to control the start of the trimming motor, realizing fast response and precise trimming, improving processing efficiency and reducing energy waste.

[0014] 2. The drive motor of this utility model drives the rotating shaft to rotate, which in turn drives the support plate and the casting on it to rotate together. The positioning rod rotates with the rotating shaft. When the positioning rod rotates to contact the pressure sensor on the support plate at both ends of the top side of the dial, the pressure sensor detects the pressure change and transmits the signal to the control panel. The casting has rotated exactly 90 degrees. The control panel controls the drive motor to stop according to the signal, which ensures the accuracy of the angle adjustment of the casting and avoids uneven trimming caused by angle deviation.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-4 As shown, a trimming device for precision casting machining includes a worktable 1. Two mounting seats 2 are installed on the top of the worktable 1. Rectangular grooves 3 are formed inside both sides of the mounting seats 2. Support rods 4 are fixedly connected between the two sides of the rectangular grooves 3. Slider 5 is slidably installed on the outer side of the support rods 4. The slider 5 is slidably installed on the inner wall of the rectangular groove 3. A tension spring 6 is fixedly connected between the slider 5 and the rectangular groove 3. The tension spring 6 is sleeved on the outer side of the support rod 4. A trigger switch 7 is installed on one side of one of the sliders 5 inside each mounting seat 2. An extrusion plate 8 is installed on one side of one of the rectangular grooves 3 inside each mounting seat 2. The extrusion plate 8 and the trigger switch 7 are on the same horizontal line. A connecting shaft is rotatably installed between the two sliders 5 inside each mounting seat 2. A trimming roller 9 is installed on the outer side of the connecting shaft. A trimming motor 10 is installed on one side of the slider 5. One end of the connecting shaft is connected to the output end of the trimming motor 10.

[0024] Servo motors 11 are mounted on both sides of the workbench 1. Threaded rods 12 are mounted on the output ends of the servo motors 11. Slide grooves 13 are formed at both ends of the workbench 1. Sliding blocks 14 are slidably mounted inside the slide grooves 13. Threaded holes are formed inside the sliding blocks 14. One end of the threaded rod 12 passes through the threaded hole and is rotatably mounted inside one side of the slide groove 13. A telescopic rod 15 is mounted on the top side of the sliding block 14. An actuating rod 16 is mounted on the actuating rod 15. Mounting seats 2 are respectively mounted on the actuating rods. At the top of the 16, a control panel 29 is installed on one side of the worktable 1. During operation, in practical applications, the mechanism for timely judgment of the contact between the trimming roller 9 and the casting is not established, requiring additional time to adjust the position of the trimming roller 9, reducing the processing efficiency of the casting. Furthermore, the trimming motor 10 will turn on before the trimming roller 9 correctly contacts the casting, resulting in energy waste. Turning on the two servo motors 11 causes the output of the servo motors 11 to drive the threaded rod 12 to rotate. The rotation of the threaded rod 12 causes the sliding block 14 to move along the thread within the groove 13. The axial movement of the trimming rod 12 causes the telescopic rod 15 to drive the action rod 16 and the mounting base 2 to move along with the sliding block 14, making the trimming roller 9 gradually approach the side of the casting. When the trimming roller 9 contacts the side of the casting, it is subjected to the reaction force of the casting, which will squeeze the slider 5 to move along the support rod 4 in the rectangular groove 3. At this time, the tension spring 6 between the slider 5 and the rectangular groove 3 is stretched. During this process, the slider 5 of the trigger switch 7 gradually approaches the extrusion plate 8 until the trigger switch 7 is triggered by the extrusion plate 8. After the trigger switch 7 is triggered, the signal is transmitted to the control panel 29. After receiving the signal, the control panel 29 controls the trimming motor 10 to start. The output end of the trimming motor 10 drives the connecting shaft to rotate, and the connecting shaft drives the trimming roller 9 to rotate at high speed, starting the trimming operation on the side of the casting. During the trimming process, by controlling the telescopic rod 15, the telescopic rod 15 drives the action rod 16 to move up and down, so that the trimming roller 9 can perform trimming operations on castings of different thicknesses, realizing fast response and precise trimming, improving processing efficiency and reducing energy waste.

[0025] Please see Figure 1 , 2 As shown in Figure 5, a mounting groove 17 is provided inside the middle of the workbench 1. A drive motor 18 is installed inside the mounting groove 17. A rotating shaft 19 is installed at the working end of the drive motor 18. The rotating shaft 19 passes through the mounting groove 17 and extends movably to the top of the workbench 1 to install a support plate 20.

[0026] A positioning rod 21 is installed on the outer side of the middle end of the rotating shaft 19. A scale 22 is installed on the top side of the worktable 1 outside the rotating shaft 19. The scale 22 is arc-shaped. Support plates 23 are installed at both ends of the top side of the scale 22. A pressure sensor 24 is installed on one side of the support plate 23. The arc between the pressure sensors 24 is ninety degrees. The pressure sensor 24 is used to monitor the pressure of the positioning rod 21 on the support plate 23.

[0027] A fixed frame 25 is installed on the top side of the workbench 1, and a cylinder 26 is installed on the top side of the fixed frame 25. A rotating shaft 27 is rotatably installed on the working end of the cylinder 26, and a pressing plate 28 is installed on the bottom side of the rotating shaft 27. The pressing plate 28 is located directly above the support plate 20. During operation, stainless steel, carbon steel, and alloy steel can all be processed into castings in the form of plates. After the plate casting is cut into the required rectangular shape, the cut edges may have burrs or unevenness, affecting the appearance quality of the plate. Therefore, an edge trimming device is required. During the edge trimming operation, since there are burrs on all four sides of the plate, the precision casting to be trimmed is placed on the support plate 20, and the cylinder 26 is activated. The working end of the cylinder 26 pushes the rotating shaft 27 downward, causing the pressing plate 28 to descend and press the casting firmly onto the support plate 20, ensuring that the casting does not shake during the edge trimming process and guaranteeing the edge trimming quality.

[0028] After the trimming of two sides of the casting is completed, the drive motor 18 is started. The actuating end of the drive motor 18 drives the rotating shaft 19 to rotate. The rotating shaft 19 drives the support plate 20 and the casting on it to rotate together. The positioning rod 21 rotates with the rotating shaft 19. When the positioning rod 21 rotates to contact the pressure sensor 24 on the support plate 23 at both ends of the top side of the dial 22, the pressure sensor 24 detects the pressure change and transmits the signal to the control panel 29. Since the arc between the two pressure sensors 24 is ninety degrees, when the positioning rod 21 rotates from one pressure sensor 24 to the other pressure sensor 24, the casting has rotated exactly ninety degrees. At this time, the control panel 29 controls the drive motor 18 to stop rotating according to the signal from the pressure sensor 24, so that the other two sides of the casting can be trimmed. This ensures the accuracy of the angle adjustment of the casting and avoids uneven trimming caused by angle deviation.

[0029] During the trimming process, the operator can directly control the trimming motor 10 to shut down through the control panel 29. When the trimming is completed or an abnormal situation occurs, the trimming operation can be stopped in time. After the trimming of all sides of the casting is completed, the control panel 29 is operated again to control the drive motor 18 to turn the casting back to the initial position. At the same time, the cylinder 26 is closed, the pressure plate 28 rises, and the trimmed casting is taken out to prepare for the trimming operation of the next casting.

[0030] Working principle: Place the precision casting to be trimmed on the support plate 20, start the cylinder 26, the action end of the cylinder 26 pushes the rotating shaft 27 to move downward, driving the pressing plate 28 to descend, pressing the casting firmly on the support plate 20, ensuring that the casting will not shake during the trimming process, and ensuring the trimming quality.

[0031] Turning on the two servo motors 11 causes their output ends to drive the threaded rod 12 to rotate. The rotation of the threaded rod 12 causes the sliding block 14 to move along the axial direction of the threaded rod 12 within the slide groove 13. The telescopic rod 15 drives the actuating rod 16 and the mounting base 2 to move with the sliding block 14, causing the trimming roller 9 to gradually approach the side of the casting. When the trimming roller 9 contacts the side of the casting, it is subjected to the reaction force of the casting, which squeezes the slider 5 to move along the support rod 4 within the rectangular groove 3. At this time, the tension spring 6 between the slider 5 and the rectangular groove 3 is stretched. During this process, the slider 5 triggered by the switch 7 gradually approaches the extrusion plate 8. The process continues until the trigger switch 7 is triggered by the extrusion plate 8. After the trigger switch 7 is triggered, the signal is transmitted to the control panel 29. After receiving the signal, the control panel 29 controls the trimming motor 10 to start. The output end of the trimming motor 10 drives the connecting shaft to rotate, and the connecting shaft drives the trimming roller 9 to rotate at high speed, starting the trimming operation on the side of the casting. During the trimming process, by controlling the telescopic rod 15, the telescopic rod 15 drives the action rod 16 to move up and down, so that the trimming roller 9 can perform trimming operations on castings of different thicknesses, realizing fast response and precise trimming, improving processing efficiency and reducing energy waste.

[0032] After the trimming of two sides of the casting is completed, the drive motor 18 is started. The actuating end of the drive motor 18 drives the rotating shaft 19 to rotate. The rotating shaft 19 drives the support plate 20 and the casting on it to rotate together. The positioning rod 21 rotates with the rotating shaft 19. When the positioning rod 21 rotates to contact the pressure sensor 24 on the support plate 23 at both ends of the top side of the dial 22, the pressure sensor 24 detects the pressure change and transmits the signal to the control panel 29. Since the arc between the two pressure sensors 24 is ninety degrees, when the positioning rod 21 rotates from one pressure sensor 24 to the other pressure sensor 24, the casting has rotated exactly ninety degrees. At this time, the control panel 29 controls the drive motor 18 to stop rotating according to the signal from the pressure sensor 24, so that the other two sides of the casting can be trimmed. This ensures the accuracy of the angle adjustment of the casting and avoids uneven trimming caused by angle deviation.

[0033] During the trimming process, the operator can directly control the trimming motor 10 to shut down via the control panel 29. When the trimming is completed or an abnormal situation occurs, the trimming operation can be stopped in time. After the trimming of all sides of the casting is completed, the control panel 29 is operated again to control the drive motor 18 to turn the casting back to the initial position. At the same time, the cylinder 26 is closed, the pressure plate 28 rises, and the trimmed casting is taken out to prepare for the trimming operation of the next casting. The specific models of the pressure sensor 24 and the trigger switch 7 are PT462E and SW-100, respectively.
