Abstract

This invention proposes a multi-station synchronous locking mechanism for a rotary disc of a divider. The mechanism includes a rotary disc, a push block, and a bonding component. The push block is longitudinally linearly slidable at the center of the rotary disc, expanding outwards from top to bottom into a frustum shape. The bonding component includes a bonding block, an elastic element, and an ejector rod. Two elastic elements form a group, and multiple groups of elastic elements are circumferentially distributed on the top of the rotary disc. The longitudinal elastic end of each elastic element passes through the top of the rotary disc. The bonding block is rotatably mounted on the elastic element and rotates outwards to contact the workpiece due to the longitudinal upward movement of the elastic element. The ejector rod is horizontally slidable inside the rotary disc, with its inner end contacting the push block. The top of the ejector rod forms an upwardly inclined stepped surface along the radial direction of the rotary disc. One end of the elastic element located inside the rotary disc contacts the inclined surface of the ejector rod. This invention converts vertical displacement into rotation of the bonding block through inclined plane-roller transmission, achieving synchronous locking.

Description

Technical Field

[0001] This utility model relates to the field of workpiece locking, and in particular to a multi-station synchronous locking mechanism for a rotary disc of a divider. Background Technology

[0002] In multi-station workpiece cutting processes, synchronous cutting technology driven by a divider is commonly used to improve production efficiency. According to existing technical solutions, each processing station is equipped with an independent locking mechanism to clamp and position the workpiece, employing a "single mechanism - single workpiece" corresponding locking mode. However, it is difficult to achieve complete synchronization in the timing of the actions of each locking mechanism. The response delay of the mechanical mechanism and differences in the signal transmission of the control system can lead to millisecond-level time deviations between stations. This asynchrony can easily cause micro-displacement of the workpiece clamping state during high-speed divider operation, thus affecting the accuracy of the cutting trajectory. Secondly, this architecture has a single-point failure risk; mechanical failure of any locking mechanism or sensor malfunction will directly cause the corresponding workpiece to lose its lock. Due to the complexity of the multi-station layout, such failures are difficult to detect in a timely manner. When the divider performs synchronous cutting, the unlocked workpiece will experience displacement deviation, causing the cutting path to deviate and leading to an increase in the defect rate. Utility Model Content

[0003] Therefore, it is necessary to provide a multi-station synchronous locking mechanism for the rotary table of a divider, which addresses the problems of difficulty in synchronizing single-mechanism single-workpiece locking in existing multi-station systems and the difficulty in timely detection of faults.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A multi-station synchronous locking mechanism for a rotary disc of a divider mainly consists of a rotary disc, a push block, and a bonding component.

[0006] The rotating disk is hollow inside.

[0007] The pusher block is linearly and longitudinally slidably positioned at the bottom center of the rotating disk, and expands outward from top to bottom into a frustum shape.

[0008] The bonding component includes a bonding block, an elastic element, and an ejector rod. Two elastic elements form a group, and multiple groups of elastic elements are circumferentially distributed on the top of the rotating disk. The longitudinal elastic end of each elastic element passes through the top of the rotating disk. The bonding block is rotatably mounted on the elastic element and rotates outward to contact the workpiece due to the longitudinal upward movement of the elastic element. The ejector rod is horizontally slidably mounted inside the rotating disk. One end of the ejector rod extends to the outside of the rotating disk, and the other end contacts the push block. The top end of the ejector rod forms an inclined upward stepped surface along the radial direction of the rotating disk from the outside to the inside. The end of the elastic element located inside the rotating disk contacts the inclined surface of the ejector rod.

[0009] Furthermore, the elastic element includes a support sleeve, a movable rod, a limiting post, a spring, and a roller; the support sleeve is connected to the top of the rotating disk, and an opening is opened on the opposite side of each set of support sleeves. The movable rod is located on the side of the limiting post away from the opening. The limiting post is fixed to the top of the movable rod and a spring is provided between it and the top of the inside of the support sleeve; a limiting groove is opened on the outer periphery of the limiting post, and the fitting block is rotatably disposed inside the support sleeve. One end of the fitting block is located in the limiting groove, and the other end faces the opening of the support sleeve. The bottom end of the movable rod extends into the rotating disk and is rotatably connected to the roller. The roller contacts the stepped surface of the top of the ejector rod.

[0010] Furthermore, the bonding block is T-shaped, with its two opposite ends located in the limiting groove of the limiting post and the opening of the support sleeve, respectively, and the other end is rotatably connected to the support sleeve. A flexible layer is bonded to the end located at the opening of the support sleeve.

[0011] Furthermore, a support frame is fixedly connected to the center of the outer bottom of the rotating disk, the fixed end of the telescopic cylinder is located inside the support frame, and the movable end of the telescopic cylinder extends upward into the interior of the rotating disk and is fixedly connected to the push block.

[0012] Furthermore, a limit rod is fixed at the inner top center of the rotating disk, and a push block is sleeved on the outer surface of the limit rod.

[0013] Furthermore, an end plate is provided at the end of the ejector rod located outside the rotating disk.

[0014] Furthermore, the rotating disk is equipped with a slide rail for supporting the ejector rod, and the slide rail is horizontally slidably connected to the ejector rod.

[0015] Furthermore, a worktable for placing workpieces is provided on top of the rotary disk and within the spacing of each set of elastic elements.

[0016] Furthermore, the worktable and the rotary table are detachably connected.

[0017] Furthermore, a protective cover is installed on the outer periphery of the support sleeve to shield the end plate and the ejector rod.

[0018] Compared with the prior art, the beneficial effects of this utility model include:

[0019] The longitudinal drive pusher is used as the core power unit. The vertical displacement is converted into the rotation of the contact block through the inclined plane-roller transmission, so as to achieve synchronous locking and avoid timing deviation. The overall operation is synchronized, avoiding the problem of untimely detection of single drive failure. Moreover, the overall structure is simple and easy to maintain and operate.

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown in the figure, this embodiment introduces a multi-station synchronous locking mechanism for a rotary disc of a divider, which mainly consists of a rotary disc 1, a push block 2, and a bonding component 3.

[0028] The rotating disk 1 adopts a hollow cylindrical structure and is a split structure, consisting of at least two parts, upper and lower. The push block 2 is longitudinally linearly slidably positioned at the bottom center of the rotating disk 1, expanding outwards from top to bottom into a frustum shape. Specifically, a limiting rod 11 can be fixed at the top center of the rotating disk 1, and a hole is opened from top to bottom along the central axis of the push block 2, with the bottom end of the limiting rod 11 located within this hole, enabling the push block 2 to move smoothly upwards and ensuring its longitudinal sliding configuration.

[0029] The push block 2 can be driven by a telescopic cylinder 5, that is, a support frame 4 is fixed at the bottom center of the rotating disk 1, and the telescopic cylinder 5 is installed in the support frame 4 and drives the push block 2 to move longitudinally.

[0030] like Figure 2 As shown, the bonding component 3 mainly consists of a bonding block 31, an elastic element 32, and an ejector rod 33. Two elastic elements 32 form a group, and multiple groups of elastic elements 32 are circumferentially distributed on the top of the rotating disk 1. The longitudinal elastic end of each elastic element 32 passes through the top of the rotating disk 1. The elastic element 32 includes a support sleeve 321, a movable rod 322, a limiting post 323, a spring 324, and a roller 325. The support sleeve 321 is connected to the top of the rotating disk 1, meaning that a hole adapted to the movable rod 322 is opened on the top of the rotating disk 1, and the bottom opening of the support sleeve 321 is set and fitted around the hole. The support sleeve 321 has a movable rod 322 inside. The bottom end of the movable rod 322 is located inside the rotating disk 1 and connected to the roller 325. The top end is fixed to a limiting post 323 with a limiting groove. The limiting groove is located on the outer circumference of the limiting post 323. The top end of the support sleeve 321 and the limiting post 323 are connected by a spring 324. The spring 324 pushes the limiting post 323 downward. It should be emphasized that the diameter of the limiting post 323 is larger than the diameter of the movable rod 322, and the side of the limiting post 323 contacts the inner wall of the support sleeve 321. The limiting post 323 does not enter the interior of the rotating disk 1. Each set of two support sleeves 321 has an opening on one side opposite to each other. A detachable worktable is set on the top of the rotating disk 1 and within the distance between the two support sleeves 321. It can be connected by a threaded connection or a quick-change snap-fit ​​structure. The worktable is used to limit the placement of workpieces, and a suitable worktable can be selected according to the shape of the workpiece.

[0031] The T-shaped fitting block 31 is installed in the support sleeve 321 via a rotating shaft. One end of the T-shaped fitting block 31 is embedded in a limiting groove, and the other end extends to the opening and is covered with a flexible layer. The middle part forms a lever structure with the rotating shaft. The flexible layer can be made of rubber or polyurethane. The ejector rod 33 horizontally penetrates the rotating disk 1. The bottom of the ejector rod 33 slides horizontally inside the rotating disk 1 via a slide rail 35. A circular end plate 34 is provided at one end of the ejector rod 33 outside the rotating disk 1, and the other end is attached to the push block 2. The top of the ejector rod 33 drives the roller 325 via a stepped surface to achieve linkage with the fitting block 31. That is, the top of the ejector rod 33 forms an upward inclined stepped surface along the radial direction of the rotating disk 1 from the outside to the inside, and the bottom end of the movable rod 322 contacts the inclined surface of the ejector rod 33 via the roller 325.

[0032] A protective cover is installed on the outer periphery of the rotating disk 1 to protect the end plate 34 and the ejector rod 33. The protective cover can be made of PC or tempered glass. When the telescopic cylinder 5 pushes the push block 2 upward, the outer conical surface of the push block 2 pushes the ejector rod 33 radially outward. The stepped surface of the ejector rod 33 forces the roller 325 to drive the movable rod 322 upward, causing the limiting post 323 to press the spring 324. At this time, the contact block 31 rotates outward around the rotating shaft under the constraint of the limiting groove, so that the flexible layer presses the workpiece. When moving in the opposite direction, the spring 324 resets, causing the mechanism to unlock, forming a synchronous locking and releasing cycle.

[0033] In this embodiment, the longitudinal drive pusher 2 is used as the core power unit. The vertical displacement is converted into the rotation of the contact block 31 through the inclined plane-roller 325 transmission, so as to achieve the purpose of synchronous locking and avoid timing deviation. The overall operation is synchronized, avoiding the problem of untimely detection of single drive failure. Moreover, the overall structure is simple and easy to maintain and operate.

[0034] Example 2

[0035] This embodiment introduces a multi-station synchronous locking mechanism for a rotary divider, which is basically the same in structure as the multi-station synchronous locking mechanism for a rotary divider described in Embodiment 1. The difference is that in this embodiment, the push block 2 can be driven by a cam lifting structure driven by a servo motor to achieve the longitudinal sliding of the push block 2.

[0036] This embodiment has the same beneficial effects as Embodiment 1.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
