Description

Technical Field

[0001] This utility model relates to the field of spring processing technology, specifically to a spring end face grinding device for spring processing. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. Springs are usually made of elastic materials, such as spring steel, which can deform under the action of external force and return to their original shape after the external force is removed. In order to ensure the stability of the spring during use and increase the contact area with the matching parts, a spring grinding device is needed to grind its end face during spring processing.

[0003] Chinese patent document CN222644001U discloses a spring-grinding device for spring processing, comprising a body for supporting components for spring grinding; a servo motor located at the bottom of the body for driving a main turntable to rotate, with a transmission rod fixedly mounted at the output end of the servo motor, the main turntable fixedly mounted at the top of the transmission rod, a fixed turntable fixedly mounted above the main turntable, a movable rod above the fixed turntable, a first drive motor fixedly mounted at one end of the movable rod, and a sub-turntable outside the movable rod; a fixed slot located on the surface of the sub-turntable for mounting an outer sleeve to the first drive motor, with a fixed block movably connected inside the fixed slot, the outer sleeve fixedly mounted at one end of the fixed block; a placement groove inside the sub-turntable, with a fixing bolt passing through the top of the placement groove, a spring cylinder movably connected at one end of the fixing bolt, a positioning rod fixedly mounted inside the spring cylinder, and a spring-grinding chamber fixedly mounted above the body.

[0004] In the above scheme, the spring is restricted from radial swaying and tilting by the cooperation of the spring cylinder and the positioning rod. During the grinding process, the high-speed rotating end face grinding head will apply tangential grinding torque when it contacts the end face of the spring. Since the spring is only placed inside the spring cylinder, the end face grinding head will drive the spring to rotate inside the spring cylinder, resulting in the spring end face not performing effective grinding work.

[0017] Example 1, as Figure 1-4 As shown, the present invention proposes a spring grinding device for end face processing, including a machine body, an adjustment component, and a limiting component. The adjustment component includes a fixed plate 1, a turntable 2, and a motor 4. The fixed plate 1 is installed on one side of the machine body, and one side is located in the end face grinding chamber. The turntable 2 is positioned above the fixed plate 1, wherein the size of the turntable 2 is the same as that of the fixed plate 1, so that one side of the turntable 2 is also located in the end face grinding chamber. The top of the turntable 2 is provided with multiple holding cylinders 3 for holding springs in use, wherein the inner dimension of the holding cylinder 3 is greater than or equal to that of the spring. The diameter is such that the bottom end of the container 3 and the top end of the fixed plate 1 have a gap, which is used to collect the metal powder being ground when the spring is located inside the container 3 during grinding, thus preventing the metal powder from accumulating on the inside of the container 3 above the fixed plate 1. The motor 4 is installed at the bottom end of the turntable 2 and connected to the fixed plate 1. The motor 4 has a speed adjustment module and a rotation angle control module, which are existing technologies and will not be described in detail here. The limiting component is set on the side of the container 3 and connected to the fixed plate 1, and its end extends to the inside of the container 3 and is connected to the spring.

[0018] In an optional embodiment, both ends of the container 3 are through-holes, so that when the spring is placed inside the container 3, the bottom end of the spring is connected to the fixing plate 1, thereby causing the container 3 to push the spring to move and preventing the debris generated by the spring grinding from depositing inside the container 3.

[0019] In an optional embodiment, an external threaded ring 13 is provided on the outer side of the container 3, and a stepped hole is provided on the end face of the turntable 2. The external threaded ring 13 is threadedly connected to the inner wall of the stepped hole of the turntable 2, so as to make it easier to disassemble and assemble the container 3 and the turntable 2.

[0020] In this embodiment, a turntable 2 driven by a motor 4 is set on a fixed plate 1, and multiple containers 3 are installed at equal angles on the turntable 2. When the motor 4 drives the turntable 2 to rotate, multiple containers 3 can be sequentially sent into the end face grinding spring chamber. When the containers 3 reach the work position, the extended end of the limiting component extends forward and probes into its interior to contact the spring, and applies radial pressure to it to achieve fastening. This ensures that the spring will not rotate when the high-speed rotating end face grinding head grinds the spring, thereby achieving stable and effective end face grinding. Since both ends of the containers 3 are through-hole and have gaps with the fixed plate 1, a channel is provided for the dust suction port, which can efficiently collect the metal dust generated during the grinding process and significantly improve the dust removal effect.

[0021] Example 2, as Figure 3As shown, the present invention proposes an end face grinding spring device for spring processing. Compared with the first embodiment, the difference in this embodiment is that the limiting component includes a cylinder 5 and a pressure block 10. The cylinder 5 is installed on the top of the fixed plate 1, and the pressure block 10 is installed on the extended end of the cylinder 5. The cylinder 5 and the pressure block 10 can be connected by an extension rod to arrange the cylinder 5 away from the container 3, or a dustproof corrugated pipe can be provided at the extended end of the cylinder 5 to prevent dust from contacting the extended rod of the cylinder 5.

[0022] In an optional embodiment, a gasket 12 is provided on the side of the pressure block 10, and a locking block 11 connected to the pressure block 10 is provided at both ends of the side of the gasket 12. The locking grooves that cooperate with the locking blocks 11 are provided at both ends of the side of the pressure block 10. The middle part of the gasket 12 is V-shaped. The gasket 12 is arranged in close contact with the pressure block 10, so that the spring can be placed in the middle of the gasket 12 for fixation, thereby making the fixation of the spring more stable.

[0023] In an optional embodiment, a through hole 14 is provided on the side of the container 3. The top end of the through hole 14 is flush with the bottom end of the turntable 2. The top end of the pressure block 10 is attached to the top end of the through hole 14 and the bottom end of the turntable 2. The size of the through hole 14 is larger than the size of the pressure block 10. When the cylinder 5 drives the pressure block 10 to move into the container 3 through the through hole 14, the pressure block 10 drives the pad 12 to press the spring inside the container 3, while preventing metal powder from accumulating on the top of the pressure block 10.

[0024] In this embodiment, the cylinder 5 drives the pressure block 10 to move into the inner side of the container cylinder 3 through the through hole 14, and causes the pressure block 10 to drive the pad 12 to contact the spring and apply radial pressure to achieve fastening. This ensures that the spring will not rotate when the high-speed rotating end face grinding head grinds the spring, thereby achieving stable and effective end face grinding. The pressure block 10 is arranged flush with the top end of the through hole 14 and the bottom end of the turntable 2, and the top end of the pressure block 10 is attached to it, so that the pressure block 10 moves along the top end of the through hole 14 and the bottom end of the turntable 2, thereby avoiding the accumulation of metal dust on the pressure block 10.

[0025] Example 3, as Figure 2As shown, the present invention proposes a spring grinding device for end face processing. Compared with Embodiment 1, this embodiment further includes a discharge hole 6 and a guide shell 7. The position of the discharge hole 6 corresponds to that of the holding cylinder 3. The discharge hole 6 is opened on the end face of the fixed plate 1. The guide shell 7 is set at the bottom of the fixed plate 1 and located directly below the discharge hole 6. The bottom inner side of the guide shell 7 is arranged in an inclined shape to discharge the spring to one side during use. The size of the discharge hole 6 is greater than or equal to the inner size of the holding cylinder 3. When the turntable 2 intermittently adjusts multiple holding cylinders 3, the springs in the holding cylinders 3 enter the end face grinding chamber for processing. The processed springs are pushed above the discharge hole 6 through the holding cylinders 3 and fall to the guide shell 7 through the discharge hole 6 by gravity, so that the springs can be automatically unloaded, improving the convenience of spring unloading.

[0026] In an optional embodiment, an orifice plate 8 is provided on the inner side of the guide shell 7 and directly below the discharge hole 6. A discharge port 9 is provided below the orifice plate 8. The orifice plate 8 is flush with the bottom of the inner side of the guide shell 7. When the spring falls through the inner side of the guide shell 7, the spring impacts the orifice plate 8 by gravity, causing the metal dust adhering to the surface of the spring to move towards the orifice plate 8, and the orifice plate 8 discharges it downward through the discharge port 9. At the same time, the guide shell 7 discharges the spring to one side, making the spring discharge more convenient and reducing the adhesion of metal dust on the surface of the spring.

[0027] In this embodiment, by opening a discharge hole 6 corresponding to the holding cylinder 3 on the end face of the fixed plate 1, when the turntable 2 drives multiple holding cylinders 3 to adjust their positions, one holding cylinder 3 is located inside the spring for processing, and another holding cylinder 3 pushes the processed spring on the fixed plate 1 to move toward the discharge hole 6, and the spring falls through the discharge hole 6 to the inside of the guide shell 7 for guiding and collection, making the discharge of the spring more convenient.

[0028] In this invention, a fixed plate 1 is fixedly installed on the machine body, and a turntable 2 driven by a motor 4 is set on the fixed plate 1. Multiple containers 3 are installed at equal angles on the turntable 2, and springs are placed inside the containers 3 and above the fixed plate 1. The motor 4 is started to drive the turntable 2 to rotate, causing the turntable 2 to sequentially feed the multiple containers 3 into the end-face grinding spring chamber. When the containers 3 reach their working position, the cylinder 5 drives the pressure block 10 to move through the through hole 14 towards the inside of the containers 3, causing the pressure block 10 to drive the gasket 12 to contact the spring and apply radial pressure to achieve a tight fit. This ensures that the spring does not rotate during the high-speed rotating end face grinding head, thus achieving stable and effective end face grinding. At the same time, the processed spring is pushed by the holding cylinder 3 onto the fixed plate 1 and moves towards the discharge hole 6, and falls into the inner side of the guide shell 7 through the discharge hole 6 for guided collection, making the unloading of the spring more convenient. During the unloading process, the spring impacts the orifice plate 8 due to gravity, and the metal dust adhering to the spring surface moves towards the orifice plate 8, and the orifice plate 8 discharges it downward through the discharge port 9, reducing the adhesion of metal dust to the spring surface.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
