Description

Technical Field

[0001] This utility model relates to the field of plate processing technology, and in particular to an intermittent plate centering mechanism. Background Technology

[0002] In the field of sheet metal processing and assembly, ensuring the precise positioning and alignment of sheets is a key step in improving product quality and production efficiency. Whether it is a sheet of metal, plastic or other materials, the positional accuracy of the sheet directly affects the accuracy of processing and the quality of the final product during processing steps such as cutting, stamping, welding, drilling and assembly. If the sheet is not precisely aligned before processing, it may lead to problems such as dimensional deviations, appearance defects, and assembly mismatches, which in turn affect the overall performance and service life of the product.

[0003] Traditional panel alignment mainly relies on manual operation, which involves manually adjusting the position of the panels to achieve alignment. However, manual alignment has many problems: on the one hand, manual operation is inefficient and cannot meet the needs of large-scale and high-efficiency production in modern industrial production; on the other hand, the accuracy of manual alignment is difficult to guarantee, and inaccurate alignment is easily caused by factors such as differences in the operator's skill level and fatigue, which in turn affects the accuracy and quality of subsequent processing or assembly. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an intermittent plate centering mechanism.

[0005] This utility model is achieved using the following technical solution: an intermittent plate centering mechanism, comprising a base, a pad fixedly connected to the upper surface of the base, a drive motor fixedly connected to the upper surface of the pad, a worm gear fixedly connected to the output end of the drive motor, a worm wheel meshing with the surface of the worm gear, a coupling rod fixedly connected to the surface of the worm wheel, a bidirectional lead screw fixedly connected to the surface of the coupling rod, movable sleeves threaded to both ends of the bidirectional lead screw, a push plate fixedly connected to the surface of the movable sleeve, and a limit rod penetrating the surface of the push plate.

[0006] The above technical solution realizes automatic alignment of the plates, avoiding the errors and inefficiencies that may occur with manual alignment, improving the accuracy and efficiency of plate alignment. At the same time, by utilizing the self-locking performance of the worm gear, it effectively prevents positional deviation caused by external forces after alignment, ensuring the stability of the plate position after alignment.

[0007] As a further improvement to the above solution, two limiting rods are provided, with the two limiting rods passing through the upper and lower sides of the push plate respectively.

[0008] The above technical solution further enhances the stability of the pusher plate's movement, prevents it from tilting or deviating during movement, and ensures that the pusher plate can accurately push the plate to the center position, thereby improving the centering accuracy and reliability.

[0009] As a further improvement to the above solution, the surface of the bidirectional lead screw is rotatably connected to a support base, which is fixedly connected to the upper surface of the base.

[0010] As a further improvement to the above solution, both the worm gear and the coupling are rotatably connected to a bearing seat, which is fixedly connected to the upper surface of the base.

[0011] The above technical solutions ensure the meshing accuracy between the worm and the worm wheel, as well as the connection stability between the coupling rod and the double-acting lead screw.

[0012] As a further improvement to the above solution, both ends of the limiting rod are fixedly connected to positioning plates, which are fixedly connected to the upper surface of the base.

[0013] The above technical solution further enhances the stability of the limiting rod, ensuring that the push plate can move smoothly along the stable limiting rod during the movement, improving the accuracy and reliability of the push plate movement, and thus ensuring the accuracy of plate alignment.

[0014] As a further improvement to the above solution, a protective cover is provided on the upper surface of the base, and the protective cover is located on the outer surface of the drive motor.

[0015] As a further improvement to the above solution, the upper surface of the protective cover is provided with several heat dissipation grooves, and a dustproof net is fixedly connected to the surface of the heat dissipation grooves.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention uses a drive motor to rotate a worm gear, which in turn drives a worm wheel and a bidirectional lead screw to rotate, achieving synchronous movement of the movable sleeve and the push plate. This automatically pushes the two side plates to the center position, ensuring the consistency and repeatability of plate alignment. It avoids the inefficiency and inaccuracy that may occur with manual alignment, significantly improving production efficiency and alignment accuracy. At the same time, the self-locking performance of the worm gear drive ensures the stability of the push plate after alignment. Even under external force, the push plate will not easily shift, avoiding the impact on the accuracy of subsequent processing or assembly due to alignment position deviation caused by external force. This effectively improves the stability and reliability of the entire production process. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-4 This embodiment of an intermittent plate alignment mechanism includes a base 1, a pad 2 fixedly connected to the upper surface of the base 1, a drive motor 3 fixedly connected to the upper surface of the pad 2, a worm gear 4 fixedly connected to the output end of the drive motor 3, a worm wheel 5 meshing with the surface of the worm gear 4, a coupling rod 6 fixedly connected to the surface of the worm wheel 5, a bidirectional lead screw 7 fixedly connected to the surface of the coupling rod 6, movable sleeves 8 threaded to both ends of the bidirectional lead screw 7, a push plate 9 fixedly connected to the surface of the movable sleeves 8, and a limit rod 10 passing through the surface of the push plate 9. When the drive motor 3 starts, the worm gear 4 rotates, driving the worm wheel 5 to rotate, thereby causing the bidirectional lead screw 7 to rotate. Both ends of the bidirectional lead screw 7 are threadedly connected to the movable sleeves 8, the movable sleeves 8 are fixedly connected to the push plate 9, and the push plate 9 passes through the limit rod 10. When the bidirectional lead screw 7 rotates, the movable sleeves 8 on both sides drive the push plate 9 to move synchronously towards the center along the limit rod 10, pushing the plates on both sides to the center position, thus completing the alignment of the plates. The worm gear 5 and worm 4 transmission have self-locking properties. Once the centering is completed, even if subjected to external force, the push plate 9 will not easily loosen, thus ensuring the stability of the centering position.

[0027] There are two limit rods 10. The two limit rods 10 pass through the upper and lower sides of the push plate 9 respectively. When the push plate 9 moves along the limit rods 10, the limit rods 10 on the upper and lower sides play a double limiting role on the push plate 9, restricting its movement direction and making it move smoothly only along the axis of the limit rods 10.

[0028] A support base 11 is rotatably connected to the surface of the bidirectional lead screw 7, and the support base 11 is fixedly connected to the upper surface of the base 1.

[0029] Both the worm gear 4 and the coupling rod 6 are rotatably connected to a bearing seat 12. The bearing seat 12 is fixedly connected to the upper surface of the base 1. The bearing seat 12 provides stable support and positioning for the worm gear 4 and the coupling rod 6, so that they can maintain good coaxiality and stability during rotation, and avoid transmission errors or damage caused by shaking or offset.

[0030] Both ends of the limiting rod 10 are fixedly connected to positioning plates 13. The positioning plates 13 are fixedly connected to the upper surface of the base 1. The positioning plates 13 provide stable support and positioning for the limiting rod 10, so that it can maintain a fixed position during the movement of the push plate 9, and prevent the limiting rod 10 from being displaced or shaking due to external force or its own vibration.

[0031] A protective cover 14 is provided on the upper surface of the base 1. The protective cover 14 is located on the outer surface of the drive motor 3. The protective cover 14 isolates the drive motor 3 from the external environment, preventing dust, debris, liquids, etc. from entering the drive motor 3. At the same time, it can also provide a certain degree of protection for the drive motor 3, preventing it from being hit or damaged by external forces.

[0032] The upper surface of the protective cover 14 has several heat dissipation slots, and a dustproof net 15 is fixedly connected to the surface of the heat dissipation slots. The dustproof net 15 dissipates heat while preventing dust and other impurities from entering the interior of the protective cover 14 through the heat dissipation slots, thus further protecting the drive motor 3.

[0033] The implementation principle of the spaced-out plate centering mechanism in this application embodiment is as follows: During operation, the drive motor 3 starts, and the worm 4 at its output end rotates accordingly. Due to the meshing relationship between the worm 4 and the worm wheel 5, the worm wheel 5 is driven to rotate. The worm wheel 5 is connected to the double-acting screw 7 through the coupling rod 6, so the double-acting screw 7 also rotates accordingly. The two ends of the double-acting screw 7 are respectively threaded to the movable sleeve block 8. The movable sleeve block 8 is fixedly connected to the push plate 9, and the push plate 9 passes through the limiting rod 10. When the double-acting screw 7 rotates, the movable sleeve blocks 8 on both sides will drive the push plate 9 to move synchronously towards the center along the limiting rod 10, thereby pushing the plates on both sides to the center position and completing the plate centering operation. Since the worm wheel 5 and worm 4 transmission has a self-locking performance, even if subjected to external force after centering, the push plate 9 will not easily loosen, thereby ensuring the stability of the centering position. Two limiting rods 10 are provided, passing through the upper and lower sides of the push plate 9 respectively. The limiting rods 10 on the upper and lower sides play a double limiting role for the push plate 9, restricting its movement direction and making it move smoothly only along the axis of the limiting rods 10. This further enhances the stability of the push plate 9's movement and ensures that the push plate 9 can accurately push the plate to the center position. The surface of the bidirectional lead screw 7 is rotatably connected to the support seat 11, which is fixedly connected to the upper surface of the base 1. This provides stable support for the bidirectional lead screw 7, enabling it to maintain good axial positioning and radial stability during rotation. This avoids shaking or deformation caused by the weight of the bidirectional lead screw 7 itself or uneven force, and improves the rotational accuracy and stability of the bidirectional lead screw 7. This ensures the movement accuracy of the movable sleeve 8 and the push plate 9, and further improves the accuracy and reliability of the plate alignment.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
