Description

Technical Field

[0001] This utility model relates to the field of spring manufacturing technology, and in particular to a spring grinding device. Background Technology

[0002] Spring grinding is an important process for improving spring quality. First, the spring is fixed on a special machine. Then, a suitable grinding compound is selected. The high-speed rotation of the machine drives the grinding tool to contact the spring, removing surface burrs and oxide layers. The grinding pressure, time and speed can be precisely controlled to ensure the dimensional accuracy and surface finish of the spring.

[0003] A search revealed Chinese Patent Publication No. CN212470804U, which discloses a spring double-end face grinding machine. The machine includes a worktable, a spring positioning mechanism mounted on the worktable, and a grinding mechanism. The spring positioning mechanism includes a positioning block with a "V"-shaped opening on its upper surface, horizontally movable on the worktable, and a pressure block with an inverted "V"-shaped opening, vertically mounted above the positioning block and always moving synchronously with the positioning block. The lengths of both the positioning block and the pressure block are less than the length of the spring product. The lifting and lowering of the pressure block is controlled by a first drive mechanism. The grinding mechanism includes a fixed grinding part fixed to one end of the positioning block and a movable grinding part movable at the end of the positioning block away from the fixed grinding part, capable of pushing the positioning block until it abuts against or moves away from the fixed grinding part. The movement of the movable grinding part is controlled by a second drive mechanism. This spring double-end face grinding machine can grind both sides of the spring simultaneously, shortening the grinding time of a single spring and thus improving spring production efficiency. However, in practical use, the above device can only grind a single spring and cannot grind springs of different models, resulting in significant limitations. Therefore, a spring grinding device is proposed to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a spring grinding device, which aims to improve the problem that the existing technology can only grind a single spring, resulting in low grinding efficiency and inability to perform continuous operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spring grinding device, comprising a worktable, a plurality of foot pads fixedly connected to the top of the worktable, a support column fixedly connected to the top of each of the foot pads, a rotating base fixedly connected to the top of each of the support columns, a rotating shaft rotatably connected to the top of the rotating base, a conveying disc fixedly connected to the top of the rotating shaft, a plurality of fixing holes being provided inside the conveying disc, a support plate fixedly connected to the top of the worktable, a device housing fixedly connected to the front side of the support plate, two hydraulic lifting cylinders fixedly connected to the top of the device housing, a fixed shaft fixedly connected between the two hydraulic lifting cylinders, a vibrating shaft fixedly connected inside the fixed shaft, a vibrating motor fixedly connected to the top of the vibrating shaft, a grinding component fixedly connected to the bottom of the vibrating shaft, and a collection mechanism provided at the rear side of the worktable for collecting the waste generated during grinding.

[0006] Through the above technical solution: the rotation of the rotating shaft can cause the conveying disc to rotate. The fixing holes on the conveying disc have multiple diameters, which can fix springs of different sizes. The hydraulic lifting rod drives the vibration motor and the vibration shaft to rise and fall, so that the grinding balls facing springs of different heights can reach the appropriate position. The vibration motor drives the vibration shaft to vibrate, which in turn causes the grinding parts to vibrate, and the grinding parts can grind the springs.

[0007] As a further description of the above technical solution:

[0008] The collecting mechanism includes a fan, the front of which is located at the rear of the workbench. The top of the fan is connected to a duct, one end of which is fixedly connected to a collecting component. The bottom of the collecting component is fixedly connected to a connecting plate, and the top of the connecting plate is fixedly connected to a sliding component. The bottom of the conveying tray has a groove, and the sliding component is slidably connected inside the groove.

[0009] Through the above technical solution, the fan can generate negative pressure through the air duct to collect the grinding waste near the collecting component. At the same time, the sliding component slides inside the chute, so that the collecting device can collect the grinding waste stably to the maximum extent. This collection is conducive to the recycling of resources and can prevent the waste from entering the device, thus extending the service life of the device.

[0010] As a further description of the above technical solution:

[0011] The bottom of the device housing is fixedly connected to a working shell, and the vibration shaft is slidably connected inside the working shell.

[0012] The above technical solution allows the vibrating shaft to work inside the working shell, while also restricting the grinding waste generated by the grinding parts, preventing it from splashing.

[0013] As a further description of the above technical solution:

[0014] A storage box is fixedly connected to the outer wall of the rotating base, and the outer wall of the storage box is rounded.

[0015] The above technical solution allows the storage box to hold springs that have not yet been ground, and the smooth outer wall of the storage box makes it more comfortable for workers to take out the springs.

[0016] As a further description of the above technical solution:

[0017] The top of each of the foot pads is threaded with a screw, one end of which is threaded to the top of the workbench.

[0018] The above technical solution uses screw threads to connect the foot pad and the worktable, making the connection between the foot pad and the worktable tighter.

[0019] As a further description of the above technical solution:

[0020] Two drawers are slidably connected to the left side of the workbench, and handles are fixedly connected to the left side of the two drawers.

[0021] Through the above technical solutions: drawers enable the workbench to have a storage function, and can store processed or unprocessed springs, while handles make it easier to pull out the drawers.

[0022] As a further description of the above technical solution:

[0023] Two knobs are fixedly connected to the front side of the workbench, and the two knobs are electrically connected to the rotating base and the vibration motor, respectively.

[0024] The above technical solution allows the knob to be electrically connected to both the rotating base and the vibrating motor, enabling the knob to control both the rotating base and the vibrating motor.

[0025] As a further description of the above technical solution:

[0026] An emergency brake button is fixedly connected to the front side of the workbench, and the emergency brake button is installed at the same height as the knob.

[0027] Through the above technical solution, the emergency vibration button can immediately stop the movement of the device when there is a problem or human error.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, starting the rotating base causes the rotating shaft of the rotating connection to rotate, which in turn drives the conveyor plate to rotate. The fixing holes on the conveyor plate have multiple diameters, which can fix springs of different sizes. Adjusting the hydraulic lifting cylinder causes the hydraulic lifting rod to drive the vibration motor and vibration shaft to rise and fall, so that the grinding balls facing springs of different heights can reach the appropriate position. Starting the vibration motor causes the vibration shaft to vibrate, which in turn causes the grinding workpiece to vibrate, thus grinding the spring.

[0030] 2. In this utility model, after grinding begins, the blower is started. The blower generates negative pressure through the air duct to collect the grinding waste near the collecting part. At the same time, the sliding part slides inside the chute, so that the collecting device can collect the grinding waste stably to the maximum extent, which is conducive to the recycling of resources. At the same time, it can prevent the waste from entering the device and extend the service life of the device. Attached Figure Description

[0038] 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 protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a spring grinding device, comprising a worktable 1. The worktable 1 has multiple foot pads 2 fixedly connected to its top, each foot pad 2 having a screw 18 threadedly connected to its top. One end of each screw 18 is threaded to the top of the worktable 1, thus connecting the foot pads 2 and the worktable 1 more tightly. Each foot pad 2 has a support column 3 fixedly connected to its top, and a rotating base 4 (model PT-GD204) fixedly connected to its top. A rotating shaft 5 is rotatably connected to the top of the rotating base 4, and a conveying disc 6 is fixedly connected to the top of the rotating shaft 5. The conveying disc 6 has multiple fixing holes 7 inside. A support plate 8 is fixedly connected to the top of the worktable 1, and a device housing 9 is fixedly connected to the front side of the support plate 8. A working shell 15 is fixedly connected to the bottom of the device housing 9, and a vibration shaft 13 is slidably connected to the inner surface of the working shell 15. The working shell 15 and the vibrating shaft 13 are slidably connected, allowing the vibrating shaft 13 to work inside and restricting the grinding waste generated by the grinding parts 14 from splashing. Two hydraulic lifting cylinders 10, model SJX-01, are fixedly connected to the top of the device shell 9. A fixed shaft 11 is fixedly connected between the two hydraulic lifting cylinders 10. The vibrating shaft 13 is fixedly connected inside the fixed shaft 11. A vibrating motor 12 is fixedly connected to the top of the vibrating shaft 13. Two knobs 21 are fixedly connected to the front side of the worktable 1. The two knobs 21 are electrically connected to the rotating base 4 and the vibrating motor 12, respectively. The knobs 21 can control the rotating base 4 and the vibrating motor 12. The grinding parts 14 are fixedly connected to the bottom of the vibrating shaft 13. A collection mechanism 16 is provided on the rear side of the worktable 1. The collection mechanism 16 is used to collect the grinding waste generated.

[0040] Specifically, the fixing holes 7 on the transport tray 6 have multiple different diameters. This design is of great significance because it allows the fixing holes 7 to effectively fix springs of different sizes, greatly improving the applicability of the device. After the springs are fixed, the hydraulic lifting cylinder 10 is adjusted. The hydraulic lifting cylinder 10 starts working, driving the vibration motor 12 and vibration shaft 13 to perform lifting and lowering actions. The vibration motor 12 is model MVE200-1. Through this adjustment, the device can reach the appropriate position when facing spring grinding parts 14 of different heights, ensuring the smooth progress of the grinding work. Next, the rotating base 4 is started by knob 21. After the rotating base 4 is started, the rotating shaft 5 connected to it starts to rotate. The rotation of the rotating shaft 5 drives the conveyor plate 6 to rotate. After the above operations are completed, the vibration motor 12 is started. After the vibration motor 12 is powered on and runs, it drives the vibration shaft 13 to vibrate, which in turn causes the grinding part 14 to vibrate, thereby completing the grinding work of the spring. In this process, through rotation and multiple station fixation, the grinding part 14 can work continuously. This working method enables the device to operate efficiently, greatly improving the efficiency of spring grinding, reducing working time and labor costs, and providing strong support for spring processing and production.

[0041] Reference Figure 2 , Figure 4 and Figure 5 The collecting mechanism 16 includes a fan 1601. The front side of the fan 1601 is located at the rear side of the workbench 1. The top of the fan 1601 is connected to a duct 1602. One end of the duct 1602 is fixedly connected to a collecting component 1603. The bottom of the collecting component 1603 is fixedly connected to a connecting plate 1604. The top of the connecting plate 1604 is fixedly connected to a sliding component 1605. The bottom of the conveying tray 6 is provided with a chute 1606. The sliding component 1605 is slidably connected inside the chute 1606.

[0042] Specifically, after grinding begins, the blower 1601 is started. Once powered on, the blower 1601 generates a strong negative pressure. This negative pressure acts on the grinding waste near the collecting component 1603 through the air duct 1602, creating a strong suction force on the grinding waste. This effectively collects the grinding waste, preventing it from scattering and maintaining a clean working environment. It also facilitates resource recycling. Simultaneously, the sliding component 1605 on the connecting plate 1604 slides inside the groove 1606 at the bottom of the conveying disc 6. This design ensures that the collecting device, composed of the collecting component 1603, the connecting plate 1604, and the sliding component 1605, remains stable throughout the operation of the conveying disc 6. This stable collecting device can collect the vast majority of the grinding waste, greatly improving the efficiency and effectiveness of waste collection. By collecting the grinding waste in a timely manner, wear and damage to the device are avoided, extending the device's service life, reducing maintenance costs, and ensuring long-term stable operation. This provides a reliable guarantee for the continuous operation of the spring grinding process.

[0043] Reference Figure 1 and Figure 3 A storage box 17 is fixedly connected to the outer wall of the rotating base 4. The outer wall of the storage box 17 is rounded. Two drawers 19 are slidably connected to the left side of the workbench 1. A handle 20 is fixedly connected to the left side of the two drawers 19. An emergency brake button 22 is fixedly connected to the front side of the workbench 1. The emergency brake button 22 is installed at the same height as the knob 21.

[0044] Specifically, the storage box 17 can store springs that have not yet been ground, and the outer wall of the storage box 17 is rounded to make it more comfortable for workers to take out the springs. The drawer 19 gives the workbench 1 a storage function and can store processed or unprocessed springs. The handle 20 makes it easier to pull the drawer 19. The emergency vibration button 22 can immediately stop the movement of the device in case of a problem or human accident.

[0045] Working principle: The fixing holes 7 on the conveyor plate 6 have multiple diameters, which can fix springs of different sizes. After the spring is fixed, the hydraulic lifting cylinder 10 is adjusted so that the hydraulic lifting cylinder 10 drives the vibration motor 12 and the vibration shaft 13 to rise and fall, so that the device can reach the appropriate position when facing spring grinding parts 14 of different heights. The rotating base 4 is started by the knob 21, which causes the rotating shaft 5 connected to the rotating base 4 to rotate. The rotation of the rotating shaft 5 drives the conveyor plate 6 to rotate. After the above operation is completed, the vibration motor 12 is started. The vibration motor 12 drives the vibration shaft 13 to vibrate, which in turn causes the grinding part 14 to vibrate, thus completing the grinding of the spring. In this process, through rotation and multiple stations being fixed together, the grinding part 14 can work continuously, making the device operate efficiently.

[0046] After grinding begins, the blower 1601 is started, which generates negative pressure. This negative pressure is then used to draw in the grinding waste near the collector 1603 through the duct 1602, thereby collecting the grinding waste. At the same time, the sliding member 1605 on the connecting plate 1604 slides inside the groove 1606 at the bottom of the conveyor plate 6. This ensures that the collection device, consisting of the collector 1603, the connecting plate 1604, and the sliding member 1605, remains stable throughout the operation of the conveyor plate 6. As a result, the collection device can collect the vast majority of the grinding waste, extending the service life of the device.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
