Description

Technical Field

[0001] The invention belongs to the technical field of camshaft burr removal, in particular to a deburring device for camshaft production. Background Art

[0002] The camshaft is a component in a piston engine. Its function is to control the opening and closing of the valves. Since the movement of the valves is related to the power and operating characteristics of an engine, the camshaft occupies a very important position in the design and operation of the engine.

[0003] Existing camshaft deburring devices often use polishing tools to remove camshaft burrs, that is, using high-speed rotating polishing tools to remove camshaft surface burrs. However, since there are multiple cams on a camshaft, and the number and size of cams on different types of camshafts are different, if the polishing tool is only fixed at a specific position of the device, it will not be possible to effectively remove all burrs on the camshaft surface.

[0004] To this end, the present invention provides a deburring device for camshaft production. Summary of the Invention

In this step, burrs on various parts of the camshaft are removed by arranging multiple grinding wheels in parallel and utilizing the difference in their horizontal positions. The vertical height of the grinding wheel and the components connected to the grinding wheel are controllable by arranging a hydraulic cylinder, thereby improving the flexibility and practicality of the device, avoiding obstruction of the camshaft by the device structure, and improving work efficiency.

This step realizes the controllable position of the supporting block by setting the second motor, thereby realizing the controllable position of the camshaft, so that multiple camshafts can pass through all grinding wheels in turn, so that multiple grinding wheels can cooperate with each other to grind all positions of the camshaft, thereby enhancing the practicality and applicability of the device.

[0009] Preferably, a first limit rod is fixed to the top of the U-shaped block, and multiple first limit rods are arranged in a symmetrical U-shaped block, and the ends of multiple first limit rods pass through the top of the fixed plate.

[0010] Preferably, a drainage plate is fixedly connected to the inner side wall of the supporting block, and the drainage plate is set corresponding to the size of the supporting block.

[0011] Preferably, a lubrication sleeve is provided inside the fixed plate, and multiple lubrication sleeves are provided corresponding to the position and size of the first limit rod.

[0012] Preferably, the limit block is made of rubber material. This step increases the friction coefficient between the limit block and the tensioning rod by making the limit block of rubber material, which is conducive to maintaining the stability of the tensioning rod and preventing the tensioning rod from sliding during operation.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] Specific examples are given below.

[0025] like Figures 1 to 5As shown, a deburring device for camshaft production according to an embodiment of the present invention comprises a workbench 1, a fixed plate 2 is fixedly connected to the interior of the workbench 1, and a plurality of fixed plates 2 are arranged in parallel, a hydraulic cylinder 15 is fixedly connected to the top of the fixed plate 2, and a U-shaped block 3 is fixedly connected to the output end of the hydraulic cylinder 15, a first motor 4 is fixedly connected to the interior of the U-shaped block 3, and a driving wheel 5 is fixedly connected to the output end of the first motor 4, a transmission track 6 is provided on the side wall of the driving wheel 5, a driven rod 8 is rotatably connected between the corresponding side walls of the U-shaped block 3, a driven wheel 7 is fixedly connected to the side wall of the driven rod 8, and the driven wheel 7 is set to the size of the transmission track 6, and the end of the driven rod 8 The bottom of the workbench 1 is fixed with a grinding wheel 14, a bearing block 18 is provided at the bottom of the workbench 1, and a hydraulic clamping block 24 is fixed on the top of the bearing block 18, and a plurality of hydraulic clamping blocks 24 are arranged in a linear array. A cooling nozzle 25 is provided on the top of the bearing block 18, and a plurality of cooling nozzles 25 are arranged corresponding to the position of the hydraulic clamping block 24. When working, the staff can drive the hydraulic clamping block 24 so that the corresponding two hydraulic clamping blocks 24 are respectively clamped at the two ends of the camshaft, thereby fixing the camshaft on the top of the bearing block 18. Subsequently, the staff can drive the first motor 4 and fix the camshaft to the top of the bearing block 18 through the hydraulic The cylinder 15 enables the U-shaped block 3 and the components connected to the U-shaped block 3 to move in the vertical direction inside the workbench 1. The staff can continuously lower the height of the grinding wheel 14 through the hydraulic cylinder 15 until the high-speed rotating grinding wheel 14 contacts the surface of the camshaft. During the process, whenever the first motor 4 is driven, the driving wheel 5 fixed to the output end of the first motor 4 will rotate. With the rotation of the driving wheel 5 and the transmission of the transmission track 6, the driven wheel 7, the driven rod 8 and the grinding wheel 14 inside the U-shaped block 3 will rotate synchronously. Among them, since multiple grinding wheels 14 are arranged in parallel inside the workbench 1 and multiple U-shaped blocks 3 There are differences in the horizontal positions of the multiple U-shaped blocks 3, which can respectively remove burrs from different positions of the camshaft. In addition, the cooling solution introduced into the interior of the carrier block 18 can be sprayed out by the cooling nozzles 25 arranged at the positions of the multiple hydraulic clamping blocks 24, thereby realizing the cooling of the camshaft. In this step, multiple grinding wheels 14 are arranged in parallel, and the burrs of various parts of the camshaft are removed by utilizing the differences in their horizontal positions. The vertical height of the grinding wheel 14 and the components connected to the grinding wheel 14 are controllable by arranging the hydraulic cylinder 15, which improves the flexibility and practicality of the device, helps to avoid the device structure from blocking the placement of the camshaft, and helps to improve work efficiency.

[0026] like Figure 4As shown, a tensioning rod 10 is fixed between the corresponding side walls of the U-shaped block 3, and a tensioning wheel 9 is rotatably connected to the side wall of the tensioning rod 10, and the tensioning wheel 9 is set corresponding to the size of the transmission track 6. The interior of the U-shaped block 3 is slidably connected to a fixing rod 12, and the two fixing rods 12 are set correspondingly. The end of the fixing rod 12 is fixedly connected to the limiting block 11, and the limiting block 11 is set corresponding to the size of the tensioning rod 10, and the end of the fixing rod 12 away from the limiting block 11 is fixedly connected to a fixing plate 13, and a screw is set between the fixing plate 13 and the U-shaped block 3. During work, the staff can use the tensioning mechanism composed of the tensioning wheel 9, the tensioning rod 10, the limiting block 11, the fixing rod 12, and the fixing plate 13 to tension the transmission track 6, thereby maintaining a good transmission effect of the transmission track 6. The operator can fix the limit block 11 and the fixing rod 12 in a preset position through the fixing plate 13. Due to the corresponding size settings of each component, whenever the operator fixes the fixing plate 13 on the side wall of the U-shaped block 3 through the screw top, the limit block 11 will be in close contact with the side wall of the tensioning rod 10 driven by the fixing rod 12. At this time, the tensioning wheel 9 will clamp the transmission track 6 with the help of the limit block 11. This step tensions the transmission track 6 by setting the tensioning wheel 9 and the tensioning rod 10, thereby improving the transmission effect of the internal components of the device. By setting the limit block 11, the fixing rod 12, and the fixing plate 13 to limit the position of the tensioning wheel 9 and the tensioning rod 10, the flexibility and convenience of the burr removal device are enhanced, which is conducive to avoiding the transmission track 6 from becoming loose during operation.

[0027] like Figure 1 and Figure 5As shown, a first fixed block 19 and a second fixed block 20 are fixedly connected to the side wall of the carrier block 18, and the first fixed block 19 and the second fixed block 20 are correspondingly arranged. A limiting platform 21 is slidably connected to the side wall of the carrier block 18, and a second limiting rod 22 is fixedly connected to the interior of the limiting platform 21, and the second limiting rod 22 corresponds to the position and size setting of the first fixed block 19. A second motor 23 is fixedly connected to the side wall of the limiting platform 21, and a threaded rod is fixedly connected to the output end of the second motor 23, and the threaded rod corresponds to the size setting of the second fixed block 20. During work, the staff can control the position of the carrier block 18 by driving the second motor 23, so that the cam shaft fixed on the top of the carrier block 18 can contact multiple grinding wheels 14. During the process, whenever the second motor 23 is in motion, the cam shaft 21 is in motion. The machine 23 is driven. Since the threaded rod fixed to the output end of the second motor 23 is in a threaded connection with the second fixed block 20, and the second limit rod 22 fixed to the inside of the limit platform 21 is in a sliding connection with the first fixed block 19, the supporting block 18 will move horizontally inside the limit platform 21, wherein the length of the limit platform 21 should ensure that all camshafts fixed between the hydraulic clamping blocks 24 can contact the grinding wheel 14. This step realizes the controllable position of the supporting block 18 by setting the second motor 23, thereby realizing the controllable position of the camshaft, so that multiple camshafts can pass through all grinding wheels 14 in turn, so that multiple grinding wheels 14 can cooperate with each other to grind all positions of the camshaft, thereby enhancing the practicality and applicability of the device.

[0028] like Figure 4 As shown, a first limit rod 16 is fixed to the top of the U-shaped block 3, and multiple first limit rods 16 are arranged symmetrically on the U-shaped block 3. The ends of the multiple first limit rods 16 pass through the top of the fixed plate 2. When working, the multiple first limit rods 16 fixed to the top of the U-shaped block 3 are in a sliding connection with the fixed plate 2. Whenever the U-shaped block 3 and the components connected to the U-shaped block 3 are moved in the vertical direction by the action of the hydraulic cylinder 15, the multiple first limit rods 16 can limit the movement posture of the U-shaped block 3 through their own contact relationship with the fixed plate 2. This step limits the movement state of the U-shaped block 3 and the components connected to the U-shaped block 3 by setting multiple first limit rods 16, thereby avoiding their displacement during the movement process, improving the stability and durability of the device, and helping to extend the service life of the device.

[0029] like Figure 5As shown, a drain plate 26 is fixedly connected to the inner wall of the supporting block 18, and the drain plate 26 is set to the size of the supporting block 18. A drainage hole is opened on the side wall of the supporting block 18. When working, the drain plate 26 fixed to the inner wall of the supporting block 18 is an inclined device as a whole. The liquid splashed during the camshaft burr removal process will be guided by the drain plate 26 and will converge at the drainage hole position. This step is beneficial to improve the liquid discharge rate by setting the drain plate 26, and is beneficial to solving the problem of liquid being difficult to discharge, thereby enhancing the practicality and convenience of the device.

[0030] like Figure 4 As shown, a lubricating sleeve 17 is provided inside the fixed plate 2, and multiple lubricating sleeves 17 are provided corresponding to the position and size of the first limit rod 16. During operation, the multiple lubricating sleeves 17 provided between the fixed plate 2 and the first limit rod 16 can reduce the friction between the components by themselves, thereby avoiding excessive wear of the first limit rod 16 and the fixed plate 2. This step reduces the friction between the components by providing the lubricating sleeves 17, thereby delaying the aging rate of the components, which is beneficial to reducing the maintenance requirements of the device and extending the service life of the device.

[0031] like Figure 4 As shown, the limit block 11 is made of rubber material. When working, the limit block 11 made of rubber material can be in close contact with the side wall of the tensioning rod 10 by being deformed by force, thereby increasing the friction between itself and the tensioning rod 10. This step increases the friction coefficient between the limit block 11 and the tensioning rod 10 by making the limit block 11 of rubber material, which is beneficial to maintaining the stability of the tensioning rod 10 and preventing the tensioning rod 10 from sliding during operation.

[0032] During operation, the staff can drive the hydraulic clamping blocks 24 so that the corresponding two hydraulic clamping blocks 24 are clamped at the two ends of the camshaft respectively, thereby fixing the camshaft on the top of the carrier block 18. Subsequently, the staff can drive the first motor 4 and use the hydraulic cylinder 15 fixed to the top of the fixed plate 2 to make the U-shaped block 3 and the components connected to the U-shaped block 3 move vertically inside the workbench 1. The staff can continue to lower the height of the grinding wheel 14 through the hydraulic cylinder 15 until the high-speed rotating grinding wheel 14 contacts the surface of the camshaft. During the process, whenever the first motor 4 is driven, the driving wheel 5 fixed to the output end of the first motor 4 will rotate. With the rotation of the driving wheel 5 and the transmission of the transmission crawler 6, the U-shaped The driven wheel 7, driven rod 8 and grinding wheel 14 inside the block 3 will rotate synchronously. Since multiple grinding wheels 14 are arranged in parallel inside the workbench 1 and the horizontal positions of multiple U-shaped blocks 3 are different, multiple U-shaped blocks 3 can remove burrs at different positions of the camshaft respectively. In addition, the cooling solution introduced into the interior of the carrier block 18 can be sprayed out from the cooling nozzles 25 arranged at the positions of multiple corresponding hydraulic clamping blocks 24, thereby realizing the cooling of the camshaft. The staff can use the tensioning mechanism composed of the tensioning wheel 9, the tensioning rod 10, the limit block 11, the fixing rod 12 and the fixing plate 13 to tension the transmission track 6, so as to maintain a good transmission effect of the transmission track 6. During the process, the staff can fix the limit block 11 and the fixing rod 12 through the fixing plate 13 In the preset position, due to the corresponding size settings of each component, whenever the staff fixes the fixing plate 13 on the side wall of the U-shaped block 3 by screwing, the limit block 11 will be in close contact with the side wall of the tensioning rod 10 under the drive of the fixing rod 12. At this time, the tensioning wheel 9 will clamp the tensioning transmission track 6 with the help of the limit block 11. The staff can control the position of the carrier block 18 by driving the second motor 23, so that the cam shaft fixed on the top of the carrier block 18 can contact multiple grinding wheels 14. During the process, whenever the second motor 23 is driven, the threaded rod fixed to the output end of the second motor 23 is in a threaded connection with the second fixed block 20, and the second limit rod 22 fixed to the inside of the limit platform 21 is in a threaded connection with the first fixed block 19. The U-shaped block 3 is in a sliding connection relationship, and the bearing block 18 will move horizontally inside the limit platform 21, wherein the length of the limit platform 21 should ensure that all camshafts fixed between the hydraulic clamping blocks 24 can contact the grinding wheel 14. Multiple first limit rods 16 fixed to the top of the U-shaped block 3 are in a sliding connection relationship with the fixed plate 2. Whenever the U-shaped block 3 and the components connected to the U-shaped block 3 are moved in the vertical direction by the action of the hydraulic cylinder 15, the multiple first limit rods 16 can limit the movement posture of the U-shaped block 3 through their own contact relationship with the fixed plate 2. The guide plate 26 fixed to the inner wall of the bearing block 18 is an overall tilting device. The liquid splashed during the camshaft burr removal process will be guided by the guide plate 26 and will converge at the drainage hole position.The multiple lubricating sleeves 17 disposed between the fixed plate 2 and the first limiting rod 16 can reduce friction between the components, preventing excessive wear of the first limiting rod 16 and the fixed plate 2. The rubber limiting block 11 can be deformed by force and tightly contact the side wall of the tensioning rod 10, increasing the friction between itself and the tensioning rod 10.
