Description

Technical Field

[0001] This utility model relates to the field of lock cylinder production, specifically to a lock cylinder grinding and polishing device. Background Technology

[0002] As the core functional component of a lock, the smoothness of the lock cylinder's outer surface directly affects the lock's assembly precision, user experience, and lifespan. In the lock cylinder manufacturing process, the core objective of the polishing step is to remove burrs, scratches, and oxide layers from the lock cylinder's outer surface. This prevents users from being scratched by sharp edges during installation or replacement, while also reducing frictional resistance between the lock cylinder and the lock body, improving the smoothness of opening and closing. With the large-scale production in the lock industry, higher demands are placed on the efficiency, precision, and security of the lock cylinder polishing process. The degree of automation in polishing equipment has become a key factor affecting enterprise production efficiency.

[0003] Initially, lock cylinder polishing relied on manual operation, typically involving hand-holding the lock cylinder and manually operating polishing tools. This method was extremely inefficient and insecure. Furthermore, manual operation depended on experience to judge polishing force and angle, easily leading to deviations in the outer roundness of the lock cylinder and uneven surface roughness, which could cause jamming during subsequent assembly with the lock body. To address the security issues of manual fixing, equipment with lock cylinder fixing and rotation functions was developed. Through the cooperation of a rotating rod and motor, it could tighten and fix both ends of lock cylinders of different lengths and drive the lock cylinder to rotate around its central axis, partially replacing manual fixing and flipping operations. However, this technical solution still has fundamental flaws; it fails to automate polishing, the polishing action still relies on manual labor, and the efficiency improvement is limited. Therefore, developing an integrated lock cylinder polishing device that can automatically fix and polish has become the key to solving the industry's technical bottleneck. Utility Model Content

[0004] The present invention aims to provide a lock cylinder grinding and polishing device, and an integrated lock cylinder grinding and polishing device that automatically fixes and grinds the cylinder.

[0005] A lock cylinder polishing device includes a worktable; a fixing component disposed on the worktable for clamping the lock cylinder and driving it to rotate around an axis; and a polishing component disposed on the worktable and opposite to the fixing component, including a polishing head and a displacement adjusting component for driving the polishing head to adjust its longitudinal and lateral displacement relative to the lock cylinder, wherein the polishing surface of the polishing head is perpendicular to the rotation axis of the lock cylinder.

[0006] The working principle and beneficial effects of this utility model: The worktable serves as a support platform. The fixing component is responsible for clamping and rotating the lock cylinder. The grinding component achieves precise alignment of the grinding head through the displacement adjustment component. By utilizing the perpendicular relationship between the grinding surface and the rotation axis of the lock cylinder, the grinding surface grinds the lock cylinder, ensuring uniform grinding of the circumference of the lock cylinder. This achieves automatic fixing and automatic grinding of the lock cylinder.

[0007] In the optimized configuration, the fixing assembly includes a left support plate and a right support plate arranged opposite to each other. The worktable is fixedly equipped with a first cylinder that drives the left support plate to move toward the right support plate. The left support plate is rotatably connected to a push rod, and the right support plate is fixedly equipped with a motor that drives a rotating rod that is directly opposite the push rod.

[0008] The first cylinder pushes the left support plate closer to the right support plate, adjusting the distance between the top rod and the rotating rod, so that the lock cylinder is clamped between the top rod and the rotating rod, quickly adapting to lock cylinders of different lengths. The rotating rod is driven to rotate by the motor, and the friction force drives the lock cylinder and the top rod to rotate synchronously, which, together with the grinding head, achieves the rotational grinding of the circumference of the lock cylinder.

[0009] In an optimized configuration, the displacement adjustment assembly includes a support frame, and the worktable is fixedly equipped with a second cylinder that drives the support frame to move laterally toward the lock cylinder, and the support frame is fixedly equipped with a third cylinder that drives the grinding head to move longitudinally toward the lock cylinder.

[0010] The second cylinder pushes the support frame to move laterally, controlling the position of the grinding head along the length of the lock cylinder to achieve grinding coverage at different axial positions; the third cylinder pushes the grinding head to move longitudinally, controlling the grinding surface of the grinding head to contact the surface of the lock cylinder.

[0011] The optimized grinding head is U-shaped, including a U-shaped grinding surface and two transverse grinding surfaces connecting the U-shaped surface. The U-shaped grinding surface fits the circumferential surface of the lock cylinder, increasing the grinding area per pass through an enveloping contact, thereby improving grinding efficiency.

[0012] In the optimized design, one of the transverse grinding surfaces is shorter than the other. This alternating design allows the shorter surface to avoid obstacles on the lock cylinder, such as keyholes, bosses, and sensor slots. Furthermore, when the lock cylinder has a stepped surface, the longer surface contacts the stepped surface. A third cylinder drives this surface back and forth, allowing it to grind the stepped surface while the shorter surface avoids obstacles on the lock cylinder.

[0013] In an optimized configuration, the right support plate is equipped with a dust collection hood, which is connected to a vacuum cleaner. Attached Figure Description

Detailed Implementation

[0016] The following detailed description illustrates the specific implementation methods: Example 1: A lock cylinder grinding and polishing device, such as Figure 1 and Figure 2 As shown, it includes a worktable 3; a fixing component, which is located on the worktable 3 and is used to clamp the lock cylinder 8 and drive it to rotate around the axis; and a grinding component, which is located on the worktable 3 and is arranged opposite to the fixing component, including a U-shaped grinding head 9 and a displacement adjustment component that drives the grinding head 9 to adjust the longitudinal and lateral displacement relative to the lock cylinder 8, wherein the grinding surface of the grinding head 9 is perpendicular to the rotation axis of the lock cylinder 8.

[0017] The fixed assembly includes a left support plate 2 and a right support plate 1 arranged opposite to each other. The worktable 3 is fixedly equipped with a first cylinder 4 that drives the left support plate 2 to move toward the right support plate 1. The left support plate 2 is rotatably connected to a push rod 10 through a bearing. The right support plate 1 and the worktable 3 are fixedly connected. The right support plate 1 is fixedly equipped with a motor 6, and the motor 6 drives a rotating rod 7 that is directly opposite the push rod 10.

[0018] The displacement adjustment assembly includes a support frame 12. The worktable 3 is fixedly provided with a second cylinder 5 that drives the support frame 12 to move laterally toward the lock cylinder 8. The support frame 12 is fixedly provided with a third cylinder 11 that drives the grinding head 9 to move longitudinally toward the lock cylinder 8.

[0019] During operation, the first cylinder 4 pushes the left support plate 2 closer to the right support plate 1, adjusting the distance between the top rod 10 and the rotating rod 7, so that the lock cylinder 8 is clamped between the top rod 10 and the rotating rod 7, quickly adapting to lock cylinders 8 of different lengths. The rotating rod 7 is driven to rotate by the motor 6, and the lock cylinder 8 and the top rod 10 rotate synchronously through friction, which, together with the grinding head 9, achieves the rotational grinding of the circumference of the lock cylinder 8.

[0020] like Figure 3 and Figure 4As shown, the second cylinder 5 pushes the support frame 12 to move laterally, controlling the position of the grinding head 9 along the length of the lock cylinder 8, so as to achieve grinding coverage at different axial positions; the third cylinder 11 pushes the grinding head 9 to move longitudinally, controlling the grinding surface of the grinding head 9 to contact the surface of the lock cylinder 8.

[0021] After polishing is complete, the polishing head 9 is disengaged from the lock cylinder 8, the left support plate 2 is moved away from the right support plate 1, and the polished lock cylinder 8 can be removed.

[0022] Example 2: As Figure 5 As shown, the grinding head 9 includes a U-shaped grinding surface and two transverse grinding surfaces connecting the U-shaped surface, wherein the length of the top transverse grinding surface is shorter than that of the bottom transverse grinding surface.

[0023] When the lock cylinder 8 has a stepped surface 13, the bottom transverse grinding surface contacts the stepped surface 13. The third cylinder 11 drives the transverse grinding surface to move back and forth, so that the longer transverse grinding surface grinds the stepped surface 13, while the shorter transverse grinding surface avoids the lock cylinder 8.
