Description

Technical Field

[0001] This utility model relates to the field of automatic locking technology, and in particular to an automatic locking device. Background Technology

[0002] An automatic locking mechanism is a device or system that can automatically lock under specific conditions. It is widely used in various fields such as machinery, engineering, and transportation. Its main function is to ensure that components or structures can lock themselves without human intervention through mechanical or electronic means, thereby enhancing safety, stability, and efficiency. Automatic locking mechanisms are typically designed to prevent loosening, improve ease of operation, and reduce human error.

[0003] In mechanical production or product inspection, it is usually necessary to clamp and fix the products to be inspected. In the existing technology, most of the clamping methods are manual clamping, that is, clamping the workpiece and fixing the product by manual operation. In some specific situations, manual clamping requires the use of other tools, such as motors, cylinders, etc., which makes the overall operation cumbersome and inconvenient. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: an automatic locking device, comprising a worktable and a support leg positioned directly below the worktable. A base plate is fixedly installed at each of the four corners of the lower surface of the worktable. The lower end of the base plate is fixedly connected to the upper surface of the support leg. A through hole is provided in the middle of the worktable, and a tapered pressure rod is movably inserted into the through hole. A positioning mechanism is provided at the upper end of the tapered pressure rod. Several fixing plates are fixedly installed at the lower end of the worktable. A fixing rod is fixedly installed on the outer surface of each fixing plate. A rotating plate is provided at the lower outer end of each fixing plate. A protruding plate is provided at the top of the rotating plate. The fixing rod and the protruding plate are rotatably connected. A clamping plate is fixedly installed at the top of the rotating plate. Spherical push rods arranged in a circular array are provided on the outer side of the tapered end of the tapered pressure rod.

[0005] The spherical push rod includes a spherical part, a push rod part, and a circular plate. The spherical part is in contact with the conical end of the conical pressure rod. The circular plate is disposed between the spherical part and the push rod part. A sleeve is provided at the end of the push rod part away from the circular plate. The sleeve is fitted into the lower end of the fixed plate. The end of the push rod part is movably inserted into the inside of the sleeve. A spring is sleeved on the outside of the push rod part. The two ends of the spring are fixedly connected to the circular plate and the sleeve, respectively.

[0006] As an improvement to the above technical solution, the plurality of fixed plates are arranged in a circumferential array, and the rotating plate and the convex plate are integrally formed.

[0007] As an improvement to the above technical solution, the rotating plate and the clamping plate are perpendicular to each other in space.

[0008] As an improvement to the above technical solution, the sleeve is located directly below the fixed rod, and the sleeve is also located inside the rotating plate.

[0009] As an improvement to the above technical solution, the end of the push rod passes through the sleeve and contacts the inner surface of the rotating plate.

[0010] As an improvement to the above technical solution, the positioning mechanism includes a positioning groove formed inside the workbench, and the positioning groove is connected to the through hole. An integrally formed positioning plate is provided on the outer side of the upper end of the tapered pressure rod, and the positioning plate and the positioning groove are corresponding and compatible.

[0011] The beneficial effects of this utility model are:

[0012] By creating a through hole inside the workbench and movably mounting a tapered pressure rod within it, with a spherical push rod positioned at the lower end of the tapered pressure rod, the tapered pressure rod and spherical push rod work together. When pressure is applied to the tapered pressure rod by the product, it moves downwards, causing the spherical push rod to move outwards. When the end of the spherical push rod pushes outwards a certain distance, both the rotating plate and the clamping plate can rotate 90 degrees. This allows the clamping plate to clamp and lock the product placed on the tapered pressure rod. The entire locking process is convenient and quick, requiring no manual intervention, thus increasing the stability and convenience of locking the product. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: an automatic locking device, including a workbench 1 and a support leg 3 located directly below the workbench 1. A base plate 2 is fixedly installed at each of the four corners of the lower surface of the workbench 1. The lower end of the base plate 2 is fixedly connected to the upper surface of the support leg 3. A through hole 11 is opened in the middle of the workbench 1. A conical pressure rod 4 is movably inserted into the through hole 11. A positioning mechanism is provided at the upper end of the conical pressure rod 4. Several fixing plates 7 are fixedly installed at the lower end of the workbench 1. A fixing rod 51 is fixedly installed on the outer surface of each fixing plate 7. A rotating plate 5 is provided at the lower outer end of the fixing plate 7. A protruding plate 52 is provided at the top of the rotating plate 5. The fixing rod 51 and the protruding plate 52 are rotatably connected. A clamping plate 6 is fixedly installed at the top of the rotating plate 5. A spherical push rod 9 distributed in a circular array is provided on the outer side of the conical end of the conical pressure rod 4.

[0020] The spherical push rod 9 includes a spherical part 91, a push rod part 92, and a circular plate 93. The spherical part 91 is in contact with the conical end of the conical pressure rod 4. The circular plate 93 is disposed between the spherical part 91 and the push rod part 92. A sleeve 8 is provided at the end of the push rod part 92 away from the circular plate 93. The sleeve 8 is fitted into the lower end of the fixed plate 7. The end of the push rod part 92 is movably inserted into the inside of the sleeve 8. A spring 10 is sleeved on the outside of the push rod part 92. The two ends of the spring 10 are fixedly connected to the circular plate 93 and the sleeve 8, respectively.

[0021] In this embodiment, a through hole 11 is opened inside the workbench 1, and a conical pressure rod 4 is movably arranged in the through hole 11. A ball push rod 9 is arranged at the lower end of the conical pressure rod 4. With the cooperation of the conical pressure rod 4 and the ball push rod 9, when the product applies pressure to the conical pressure rod 4, the conical pressure rod 4 can move downward, thereby driving the ball push rod 9 to move outward. When the end of the ball push rod 9 pushes outward a certain distance, the rotating plate 5 and the clamping plate 6 can both be rotated ninety degrees, so that the clamping plate 6 can clamp and lock the product placed on the conical pressure rod 4. The whole locking process is convenient and quick.

[0022] Specifically, several fixed plates 7 are arranged in a circular array, and the rotating plate 5 and the convex plate 52 are integrally formed.

[0023] Specifically, the rotating plate 5 and the clamping plate 6 are perpendicular to each other in space.

[0024] Specifically, the sleeve 8 is located directly below the fixed rod 51, and the sleeve 8 is also located inside the rotating plate 5. The end of the push rod 92 passes through the sleeve 8 and contacts the inner surface of the rotating plate 5.

[0025] Specifically, the positioning mechanism includes a positioning groove 12 inside the workbench 1, and the positioning groove 12 is connected to the through hole 11. An integrally formed positioning plate 41 is provided on the outer side of the upper end of the tapered pressure rod 4, and the positioning plate 41 and the positioning groove 12 are in corresponding and compatible positions.

[0026] In this embodiment, by setting a positioning mechanism on the outer side of the upper end of the tapered pressure rod 4, the positioning plate 41 and the positioning groove 12 in the positioning mechanism can make the tapered pressure rod 4 move up and down stably, avoiding the tapered pressure rod 4 from deviating during the movement.

[0027] Working principle and process: In use, first place the product to be clamped and locked on the worktable 1. During the placement process, the end of the conical pressure rod 4 needs to be squeezed, and the conical pressure rod 4 begins to move downward under the external force. At this time, the ball push rod 9 set on the outer side of the conical part at the lower end of the conical pressure rod 4 moves outward. During the outward movement of the ball push rod 9, the ball part 91 slides on the conical surface, and the push rod part 92 passes through the sleeve 8 and begins to push out the rotating plate 5. The spring 10 begins to contract. When the sleeve 8 is completely pushed out of the rotating plate 5, the rotating plate 5 rotates up to 90 degrees due to the linear motion of the sleeve 8. Similarly, the clamping plate 6 also rotates 90 degrees. At this time, the clamping plate 6 can clamp and lock the product placed on the worktable 1. When the product is removed, the conical pressure rod 4 is not squeezed by external force and begins to reset under the action of the spring 10, waiting for the clamping and locking of the next product.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
