Description

Technical Field

[0001] The utility model relates to the technical field of die casting, and particularly relates to a die-casting part grinding device. Background Art

[0002] With the continuous development of industry, die-casting parts are more and more widely used in various fields. During the production process of die-casting parts, burrs, flash and other defects often exist on their surfaces, and grinding treatment is required to improve the quality and appearance of the products.

[0003] The traditional grinding method for die-casting parts mainly relies on manual operation, which not only has low efficiency, but also has a large labor intensity, and it is difficult to guarantee the grinding quality. At the same time, the dust and noise generated during manual grinding also have certain harms to the physical health of operators.

[0004] Therefore, we propose a die-casting part grinding device. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a die-casting part grinding device, in order to prevent problems such as low efficiency of manual grinding, large labor intensity, difficult guarantee of grinding quality, and harms to the physical health of operators caused by dust and noise generated during manual grinding, so as to improve the grinding efficiency and quality of die-casting parts, reduce the labor intensity, and reduce the harms to operators, and can effectively solve the problems in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A die-casting part grinding device, including a workbench, a protective cover is provided at the top end of the workbench, visual windows are provided at both ends of the protective cover, an adjusting mechanism, a grinding mechanism and a clamping mechanism are provided above the workbench, the adjusting mechanism is connected to the grinding mechanism, and the grinding mechanism is located between the adjusting mechanism and the clamping mechanism, two groups of relatively parallel columns are fixedly connected to the top end of the workbench, and a moving plate is slidably connected to the inner sides of the two groups of columns;

[0008] The adjusting mechanism includes a bracket fixedly connected to the bottom end of the moving plate, a connecting shaft is rotatably connected to the middle of the bracket, the top end of the connecting shaft passes through the bracket and is rotatably connected to the middle of the inner wall of the bottom end of the moving plate, a secondary gear is fixedly connected to the outside of the connecting shaft and between the moving plate and the bracket, a first driving motor is fixedly installed on the lower end surface of the bracket, an output shaft of the first driving motor passes through the bracket and is fixedly connected to a main gear, and the main gear meshes with the secondary gear;

[0009] The bottom end of the connecting shaft is fixedly connected with a fixed seat. Two symmetrically arranged support plates are fixedly connected to the lower end surface of the fixed seat. A first worm gear is arranged between the two support plates. Two symmetrically arranged ear plates are also fixedly connected to the lower end surface of the fixed seat. A first worm is arranged above the first worm gear between the two ear plates. The two ends of the first worm pass through the ear plates and are rotatably connected to the ear plates through bearings. The first worm meshes with the first worm gear;

[0010] At the edge of the top end of the fixed seat, a second driving motor is fixedly connected by bolts. Two belt pulleys are arranged at one end of the second driving motor. A belt is arranged between the two belt pulleys. The belt bypasses the two belt pulleys. One of the belt pulleys is coaxially and fixedly connected to the output shaft of the second driving motor, and the other belt pulley is coaxially and fixedly connected to one end of the first worm;

[0011] Cross bars are arranged at both ends of the first worm gear. Two symmetrically arranged connecting plates are fixedly connected to the outer side of the cross bars. The top ends of the connecting plates are fixedly connected with a connecting frame;

[0012] The clamping mechanism includes a sliding seat slidably connected to the top end of the workbench. A second worm is rotatably connected to the inner wall of one end of the sliding seat. A third driving motor is fixedly installed on the outer wall of one end of the sliding seat. The output shaft of the third driving motor penetrates through the sliding seat and is fixedly connected to the second worm. A second worm gear is rotatably connected to the inner wall of the top end of the sliding seat. The second worm gear meshes with the second worm. Two sets of relatively parallel link mechanisms are arranged on one side of the second worm gear. Clamping plates are arranged at the ends of the two sets of link mechanisms away from the second worm gear and are relatively parallel to each other. An adjusting bolt for fixing the sliding seat is arranged on the inner wall of the top end of the second sliding seat.

[0013] By adopting the above technical solution, first, place the die-casting part to be polished between the two clamping plates of the clamping mechanism. Start the third driving motor. Its output shaft drives the second worm to rotate. Since the second worm meshes with the second worm gear, the rotation of the second worm causes the second worm gear to rotate. The rotation of the second worm gear drives the connected link mechanism to move, so that the two clamping plates approach each other and clamp the die-casting part. The adjusting bolt can be used to fix the position of the sliding seat to ensure stable clamping;

[0014] Next, the position and angle of the grinding mechanism are adjusted through the adjustment mechanism. The first driving motor is started, and its output shaft drives the main gear to rotate. Since the main gear meshes with the secondary gear, the rotation of the main gear causes the secondary gear to rotate, which in turn drives the connecting shaft to rotate. The rotation of the connecting shaft causes the fixed seat to rotate, thereby adjusting the angle of the grinding mechanism. At the same time, the second driving motor is started, and its output shaft drives a pulley to rotate. Through the transmission of the belt, the other pulley also rotates, which in turn drives the first worm to rotate. Since the first worm meshes with the first worm gear, the rotation of the first worm causes the first worm gear to rotate. The cross bars at both ends of the first worm gear drive the connecting plate and the connecting frame to move, further adjusting the position of the grinding mechanism.

[0015] When the grinding mechanism is adjusted to the appropriate position and angle, the die-casting part is started to be ground. During the grinding process, the protective cover at the top of the workbench can prevent the debris generated by grinding from splashing, and the visual windows at both ends facilitate the operator to observe the grinding situation.

[0016] The moving plates on the inner sides of the two groups of columns can slide within a certain range, providing support and guidance for the movement of the adjustment mechanism and the grinding mechanism.

[0017] Furthermore, the grinding mechanism includes a grinding motor fixedly installed on the inner wall of the bottom end of the connecting frame. The output shaft of the grinding motor penetrates through the connecting frame and is fixedly installed with a grinding wheel.

[0018] By adopting the above technical solution, when the entire die-casting part grinding device starts to operate, the grinding motor is started, and the output shaft of the grinding motor rotates, driving the grinding wheel to rotate at a high speed. Under the action of the adjustment mechanism, the connecting frame and the grinding motor and grinding wheel fixedly installed on its inner wall of the bottom end are adjusted to the appropriate position and angle, so that the grinding wheel can contact the surface of the die-casting part clamped by the clamping mechanism. The high-speed rotating grinding wheel generates friction with the surface of the die-casting part, thereby removing defects such as burrs and flash on the surface of the die-casting part, realizing the grinding process of the die-casting part; during the grinding process, due to the high-speed rotation and specific material of the grinding wheel, the die-casting part can be effectively cut and polished, improving the surface quality of the die-casting part.

[0019] Furthermore, the link mechanism includes a first connecting rod, a second connecting rod and a third connecting rod. The first connecting rod is rotatably connected to the bottom end of the second worm gear. One end of the first connecting rod away from the second worm gear is rotatably connected to the second connecting rod. One end of the second connecting rod away from the first connecting rod is rotatably connected to the clamping plate with damping.

[0020] By adopting the above technical solution, since the first connecting rod is rotatably connected to the bottom end of the second worm gear, the rotation of the second worm gear will drive the first connecting rod to move. One end of the first connecting rod away from the second worm gear is rotatably connected to the second connecting rod. Therefore, the movement of the first connecting rod will drive the second connecting rod to move. One end of the second connecting rod away from the first connecting rod is damping rotatably connected to the clamping plate. Finally, the movement of the second connecting rod pushes the clamping plate to move, realizing the mutual approach or separation of the two clamping plates, thereby clamping or loosening the die-casting part. Through the design of this link mechanism, through the rotational connection of multiple rods, the rotational movement of the second worm gear can be converted into the linear movement of the clamping plate, realizing the clamping and loosening operations of the die-casting part, and the damping rotational connection can increase the stability and controllability of the operation to a certain extent.

[0021] Further, one end of the third connecting rod is rotatably connected to the inner wall of the top end of the sliding seat, and the end of the third connecting rod away from the sliding seat is rotatably connected to the bottom end of the second connecting rod.

[0022] By adopting the above technical solution, the second worm gear drives the first connecting rod to move, and the connecting end of the first connecting rod and the second connecting rod undergoes displacement. At the same time, since one end of the third connecting rod is rotatably connected to the inner wall of the top end of the sliding seat and the other end is rotatably connected to the bottom end of the second connecting rod, during the movement of the first connecting rod and the second connecting rod, the third connecting rod plays a role in stabilizing and guiding the movement direction. As the second worm gear continues to rotate, the first connecting rod, the second connecting rod, and the third connecting rod cooperate with each other to move, so that the end of the second connecting rod connected to the clamping plate pushes the clamping plate to move, realizing the mutual approach of the two clamping plates to clamp the die-casting part, or the mutual separation to loosen the die-casting part. Through this link mechanism composed of the first connecting rod, the second connecting rod, and the third connecting rod, and through the coordinated action of multiple rotation connection points, the rotational movement of the second worm gear can be more stably converted into the linear movement of the clamping plate, improving the reliability and accuracy of the clamping mechanism.

[0023] Further, a cross beam is fixedly connected to the upper part of the inner sides of the two groups of columns, and an electric push rod is fixedly installed in the middle of the top end of the cross beam. The output end of the electric push rod penetrates through the cross beam and is connected to the middle of the top end of the moving plate.

[0024] By adopting the above technical solution, when it is necessary to adjust the height of the grinding mechanism, start the electric push rod, and the output end of the electric push rod performs telescopic movement. Since the output end of the electric push rod penetrates through the cross beam and is connected to the middle of the top end of the moving plate, when the output end of the electric push rod extends, it will push the moving plate to move downward along the inner sides of the two groups of columns; conversely, when the output end of the electric push rod shortens, it will pull the moving plate to move upward along the inner sides of the two groups of columns. The up and down movement of the moving plate drives the adjusting mechanism and the grinding mechanism connected thereto to move up and down as a whole, thereby realizing the adjustment of the height of the grinding mechanism to adapt to die-casting parts of different sizes and different grinding requirements.

[0025] Furthermore, two sets of parallelly arranged limiting rods are fixedly connected to the top end of the moving plate, and the top ends of the limiting rods penetrate through the cross beam and are slidably connected to the cross beam.

[0026] By adopting the above technical solution, during the up and down movement of the moving plate along with the electric push rod, the two sets of relatively parallelly arranged limiting rods play a role in restricting the moving direction of the moving plate and ensuring the moving stability; when the electric push rod pushes or pulls the moving plate, the top ends of the limiting rods slide in the cross beam. Since the limiting rods can only move along their axial directions, the moving plate is restricted to move vertically up and down, preventing the moving plate from tilting, shaking or deviating from the predetermined moving track during the movement. In this way, it can ensure that the grinding mechanism can reach the required position smoothly and accurately when adjusting the height, improving the operation precision and reliability of the entire device.

[0027] Compared with the prior art, the utility model has the following beneficial effects:

[0028] (1) For a die-casting part grinding device of the utility model, the device can realize multi-angle and multi-direction adjustment of the grinding mechanism through the adjustment mechanism. The first driving motor drives the main gear and the auxiliary gear to rotate, so that the connecting shaft rotates to adjust the angle of the grinding mechanism; the second driving motor drives the first worm to rotate through the belt pulley and the belt, and then the first worm wheel rotates to adjust the position of the grinding mechanism; this fine adjustment function can enable the grinding mechanism to accurately align different parts of the die-casting part, adapt to die-casting parts of various complex shapes, and greatly improve the grinding precision and adaptability.

[0029] (2) For a die-casting part grinding device of the utility model, the link mechanism in the clamping mechanism can stably clamp the die-casting part to ensure that the die-casting part does not displace during the grinding process. At the same time, the sliding seat can slide on the workbench and is fixed by adjusting bolts, which is convenient for adjusting the position according to die-casting parts of different sizes, further improving the adaptability of the device to different die-casting parts.

[0030] (3) For a die-casting part grinding device of the utility model, the protective cover at the top end of the workbench can effectively prevent the grinding debris from splashing, protecting the operator from being injured. The visual windows at both ends facilitate the operator to observe the grinding situation in a safe environment, timely adjust the grinding parameters, and improve the operation safety.

Specific embodiments

[0035] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0036] In order to prevent problems such as low efficiency of manual grinding, high labor intensity, difficulty in guaranteeing grinding quality, and harm to the physical health of operators caused by dust and noise generated by manual grinding, so as to improve the grinding efficiency and quality of die-casting parts, reduce labor intensity, and reduce harm to operators, as Figure 1 , Figure 2 , Figure 3 shown, a die-casting part grinding device includes a workbench 1, a protective cover 32 is provided at the top end of the workbench 1, viewing windows 33 are provided at both ends of the protective cover 32, an adjusting mechanism 2, a grinding mechanism and a clamping mechanism 4 are provided above the workbench 1, the adjusting mechanism 2 is connected to the grinding mechanism 3, and the grinding mechanism 3 is located between the adjusting mechanism 2 and the clamping mechanism 4, two groups of relatively parallel columns 34 are fixedly connected to the top end of the workbench 1, and a moving plate 5 is slidably connected to the inner sides of the two groups of columns 34;

[0037] The adjusting mechanism 2 includes a bracket 6 fixedly connected to the bottom end of the moving plate 5, a connecting shaft 7 is rotatably connected to the middle of the bracket 6, the top end of the connecting shaft 7 passes through the bracket 6 and is rotatably connected to the middle of the inner wall of the bottom end of the moving plate 5, a secondary gear 8 is fixedly connected to the outside of the connecting shaft 7 and between the moving plate 5 and the bracket 6, a first driving motor 9 is fixedly installed on the lower end surface of the bracket 6, an output shaft of the first driving motor 9 passes through the bracket 6 and is fixedly connected to a main gear 10, and the main gear 10 meshes with the secondary gear 8;

[0038] The bottom end of the connecting shaft 7 is fixedly connected with a fixed seat 11. Two symmetrically arranged support plates 12 are fixedly connected to the lower end surface of the fixed seat 11. A first worm gear 15 is arranged between the two support plates 12. Two symmetrically arranged ear plates 13 are also fixedly connected to the lower end surface of the fixed seat 11. A first worm 14 is arranged above the first worm gear 15 between the two ear plates 13. Both ends of the first worm 14 pass through the ear plates 13 and are rotatably connected to the ear plates 13 through bearings. The first worm 14 meshes with the first worm gear 15;

[0039] At the edge of the top end of the fixed seat 11, a second driving motor 16 is fixedly connected by bolts. Two belt pulleys 17 are arranged at one end of the second driving motor 16. A belt 18 is arranged between the two belt pulleys 17. The belt 18 bypasses the two belt pulleys 17. One of the belt pulleys 17 is coaxially and fixedly connected to the output shaft of the second driving motor 16, and the other belt pulley 17 is coaxially and fixedly connected to one end of the first worm 14;

[0040] Cross bars are arranged at both ends of the first worm gear 15. Two symmetrically arranged connecting plates 20 are fixedly connected to the outer sides of the cross bars. The top ends of the connecting plates 20 are fixedly connected with a connecting frame 19;

[0041] The clamping mechanism 4 includes a sliding seat 23 slidably connected to the top end of the workbench 1. A second worm 25 is rotatably connected to the inner wall of one end of the sliding seat 23. A third driving motor 24 is fixedly installed on the outer wall of one end of the sliding seat 23. The output shaft of the third driving motor 24 penetrates through the sliding seat 23 and is fixedly connected with the second worm 25. A second worm gear 26 is rotatably connected to the inner wall of the top end of the sliding seat 23. The second worm gear 26 meshes with the second worm 25. Two groups of relatively parallel link mechanisms are arranged on one side of the second worm gear 26. Clamping plates 30 arranged relatively parallel are arranged at the ends of the two groups of link mechanisms far away from the second worm gear 26. An adjusting bolt 31 for fixing the sliding seat 23 is arranged on the inner wall of the top end of the second sliding seat 23.

[0042] During use, first, place the die-casting part to be polished between the two clamping plates 30 of the clamping mechanism 4. Start the third driving motor 24, and its output shaft drives the second worm 25 to rotate. Since the second worm 25 meshes with the second worm gear 26, the rotation of the second worm 25 causes the second worm gear 26 to rotate. The rotation of the second worm gear 26 drives the connected link mechanism to move, so that the two clamping plates 30 approach each other and clamp the die-casting part. The adjusting bolt 31 can be used to fix the position of the sliding seat 23 to ensure stable clamping;

[0043] Next, the position and angle of the grinding mechanism 3 are adjusted by the adjustment mechanism 2. The first driving motor 9 is started, and its output shaft drives the main gear 10 to rotate. Since the main gear 10 meshes with the sub-gear 8, the rotation of the main gear 10 causes the sub-gear 8 to rotate, which in turn drives the connecting shaft 7 to rotate. The rotation of the connecting shaft 7 causes the fixed seat 11 to rotate, thereby adjusting the angle of the grinding mechanism 3. At the same time, the second driving motor 16 is started, and its output shaft drives a pulley 17 to rotate. Through the transmission of the belt 18, the other pulley 17 also rotates, which in turn drives the first worm 14 to rotate. Since the first worm 14 meshes with the first worm gear 15, the rotation of the first worm 14 causes the first worm gear 15 to rotate. The cross bars at both ends of the first worm gear 15 drive the connecting plate 20 and the connecting frame 19 to move, further adjusting the position of the grinding mechanism 3.

[0044] When the grinding mechanism 3 is adjusted to the appropriate position and angle, the die-casting part is started to be ground. During the grinding process, the protective cover 32 at the top of the workbench 1 can prevent the chips generated by grinding from splashing, and the visual windows 33 at both ends facilitate the operator to observe the grinding situation.

[0045] The moving plates 5 inside the two groups of columns 34 can slide within a certain range, providing support and guidance for the movement of the adjustment mechanism 2 and the grinding mechanism 3.

[0046] Exemplarily, as Figure 1 、 Figure 2 、 Figure 3 shown, the present utility model further includes that the grinding mechanism 3 includes a grinding motor 21 fixedly installed on the inner wall of the bottom end of the connecting frame 19, and the output shaft of the grinding motor 21 penetrates through the connecting frame 19 and is fixedly installed with a grinding wheel 22.

[0047] During use, when the entire die-casting part grinding device starts to operate, the grinding motor 21 is started, and the output shaft of the grinding motor 21 rotates, driving the grinding wheel 22 to rotate at a high speed. Under the action of the adjustment mechanism 2, the connecting frame 19 and the grinding motor 21 and the grinding wheel 22 fixedly installed on its inner wall of the bottom end are adjusted to the appropriate position and angle, so that the grinding wheel 22 can contact the surface of the die-casting part clamped by the clamping mechanism 4. The high-speed rotating grinding wheel 22 generates friction with the surface of the die-casting part, thereby removing defects such as burrs and flash on the surface of the die-casting part, realizing the grinding process of the die-casting part. During the grinding process, due to the high-speed rotation and specific material of the grinding wheel 22, the die-casting part can be effectively cut and polished, improving the surface quality of the die-casting part.

[0048] Exemplarily, as Figure 2 、 Figure 3As shown, the present utility model further includes. The link mechanism includes a first connecting rod 27, a second connecting rod 28, and a third connecting rod 29. The first connecting rod 27 is rotatably connected to the bottom end of the second worm gear 26. One end of the first connecting rod 27 away from the second worm gear 26 is rotatably connected to the second connecting rod 28. One end of the second connecting rod 28 away from the first connecting rod 27 is rotatably connected to the clamping plate 30 with damping.

[0049] During use, since the first connecting rod 27 is rotatably connected to the bottom end of the second worm gear 26, the rotation of the second worm gear 26 will drive the first connecting rod 27 to move. One end of the first connecting rod 27 away from the second worm gear 26 is rotatably connected to the second connecting rod 28. Therefore, the movement of the first connecting rod 27 will drive the second connecting rod 28 to move. One end of the second connecting rod 28 away from the first connecting rod 27 is rotatably connected to the clamping plate 30 with damping. Finally, the movement of the second connecting rod 28 pushes the clamping plate 30 to move, realizing the mutual approach or separation of the two clamping plates 30, thereby clamping or loosening the die-casting part. Through the design of this link mechanism, through the rotational connection of multiple rods, the rotational movement of the second worm gear 26 can be converted into the linear movement of the clamping plate 30, realizing the clamping and loosening operations of the die-casting part, and the damping rotational connection can increase the stability and controllability of the operation to a certain extent.

[0050] Exemplarily, as Figure 2 、 Figure 3 As shown, the present utility model further includes. One end of the third connecting rod 29 is rotatably connected to the inner wall of the top end of the sliding seat 23. The end of the third connecting rod 29 away from the sliding seat 23 is rotatably connected to the bottom end of the second connecting rod 28.

[0051] During use, the second worm gear 26 drives the first connecting rod 27 to move, and the connecting end of the first connecting rod 27 and the second connecting rod 28 undergoes displacement. At the same time, since one end of the third connecting rod 29 is rotatably connected to the inner wall of the top end of the sliding seat 23 and the other end is rotatably connected to the bottom end of the second connecting rod 28, during the movement of the first connecting rod 27 and the second connecting rod 28, the third connecting rod 29 plays a role in stabilizing and guiding the movement direction. As the second worm gear 26 continues to rotate, the first connecting rod 27, the second connecting rod 28, and the third connecting rod 29 cooperate with each other to move, so that the end of the second connecting rod 28 connected to the clamping plate 30 pushes the clamping plate 30 to move, realizing the mutual approach of the two clamping plates 30 to clamp the die-casting part, or the mutual separation to loosen the die-casting part. Through this link mechanism composed of the first connecting rod 27, the second connecting rod 28, and the third connecting rod 29, and through the coordinated action of multiple rotational connection points, the rotational movement of the second worm gear 26 can be more stably converted into the linear movement of the clamping plate 30, improving the reliability and accuracy of the clamping mechanism.

[0052] Exemplarily, as Figure 2 、 Figure 3As shown, the utility model further includes that two upper parts inside the columns 34 are fixedly connected with a cross beam 35, and the middle part of the top end of the cross beam 35 is fixedly installed with an electric push rod 36. The output end of the electric push rod 36 penetrates through the cross beam 35 and is connected with the middle part of the top end of the moving plate 5.

[0053] When in use, when it is necessary to adjust the height of the grinding mechanism 3, start the electric push rod 36. The output end of the electric push rod 36 performs telescopic movement. Since the output end of the electric push rod 36 penetrates through the cross beam 35 and is connected with the middle part of the top end of the moving plate 5, when the output end of the electric push rod 36 extends, it will push the moving plate 5 to move downward along the inner sides of the two columns 34; on the contrary, when the output end of the electric push rod 36 shortens, it will pull the moving plate 5 to move upward along the inner sides of the two columns 34; the up and down movement of the moving plate 5 drives the adjusting mechanism 2 and the grinding mechanism 3 connected thereto to move up and down as a whole, so as to realize the adjustment of the height of the grinding mechanism 3 to adapt to different sizes of die-castings and different grinding requirements.

[0054] Exemplarily, as Figure 2 、 Figure 3 shown, the utility model further includes that two relatively parallel and horizontally arranged limiting rods 37 are fixedly connected to the top end of the moving plate 5. The top ends of the limiting rods 37 penetrate through the cross beam 35 and are slidably connected with the cross beam 35.

[0055] When in use, during the up and down movement of the moving plate 5 along with the electric push rod 36, the two relatively parallel and horizontally arranged limiting rods 37 play a role in restricting the moving direction of the moving plate 5 and ensuring the moving stability; when the electric push rod 36 pushes or pulls the moving plate 5, the top ends of the limiting rods 37 slide in the cross beam 35. Since the limiting rods 37 can only move along their axial directions, the moving plate 5 is restricted to move up and down only in the vertical direction, preventing the moving plate 5 from tilting, shaking or deviating from the predetermined moving track during the moving process. In this way, it can be ensured that the grinding mechanism 3 can reach the required position smoothly and accurately when the height is adjusted, improving the operation precision and reliability of the whole device.

[0056] It should be noted that the utility model is a die-casting grinding device. Place the die-casting to be ground between the two clamping plates 30 of the clamping mechanism 4, start the third driving motor 24, and its output shaft drives the second worm 25 to rotate. Since the second worm 25 meshes with the second worm gear 26, the rotation of the second worm 25 causes the second worm gear 26 to rotate. The rotation of the second worm gear 26 drives the connecting rod mechanism connected thereto to move, so that the two clamping plates 30 approach each other and clamp the die-casting. The adjusting bolt 31 can be used to fix the position of the sliding seat 23 to ensure stable clamping;

[0057] The position and angle of the grinding mechanism 3 are adjusted by the adjusting mechanism 2. The first driving motor 9 is started, and its output shaft drives the main gear 10 to rotate. Since the main gear 10 meshes with the secondary gear 8, the rotation of the main gear 10 causes the secondary gear 8 to rotate, thereby driving the connecting shaft 7 to rotate. The rotation of the connecting shaft 7 causes the fixed seat 11 to rotate, thus adjusting the angle of the grinding mechanism 3. At the same time, the second driving motor 16 is started, and its output shaft drives a pulley 17 to rotate. Through the transmission of the belt 18, the other pulley 17 also rotates, thereby driving the first worm 14 to rotate. Since the first worm 14 meshes with the first worm gear 15, the rotation of the first worm 14 causes the first worm gear 15 to rotate. The cross bars at both ends of the first worm gear 15 drive the connecting plate 20 and the connecting frame 19 to move, further adjusting the position of the grinding mechanism 3.

[0058] When the grinding mechanism 3 is adjusted to the appropriate position and angle, the die-casting part is started to be ground. During the grinding process, the protective cover 32 at the top of the workbench 1 can prevent the debris generated by grinding from splashing, and the visual windows 33 at both ends facilitate the operator to observe the grinding situation.

[0059] The moving plates 5 inside the two groups of columns 34 can slide within a certain range, providing support and guidance for the movement of the adjusting mechanism 2 and the grinding mechanism 3.
