Description

Technical Field

[0001] This utility model relates to the field of high-speed chain technology, specifically a positioning mechanism for a high-speed chain tooling plate. Background Technology

[0002] Production lines composed of double-speed chain conveyors are usually called gravity-flow conveying systems. They are mainly used for material conveying in assembly and processing production lines. The conveying principle is to use the speed-increasing function of the double-speed chain to make the tooling plates supporting the goods run quickly. They stop at the corresponding operating positions through the stopper, or complete the functions of accumulation, transfer, indexing and line transfer through the corresponding instructions.

[0003] Chinese Patent Application No. CN202322791557.9 discloses a V-shaped positioning mechanism for a 1x speed chain conveyor tooling plate, including a base. The base has an internal conveying mechanism and an external positioning mechanism. A loading mechanism is located on top of the conveying mechanism. The positioning mechanism includes a mounting plate with an electric push rod fixedly connected to its top. A positioning block is fixedly connected to the output end of the electric push rod. A baffle is fixedly connected to the external side of the base, and a distance sensor is fixedly connected to the left side of the baffle. In this V-shaped positioning mechanism for a 1x speed chain conveyor tooling plate, when the pallet is about to contact the distance sensor on the left side of the baffle, the distance sensor transmits distance information to a controller. The controller then randomly controls the electric push rod to open, pushing the positioning block upwards until it engages with the V-shaped retainer at the bottom of the pallet. The electric push rod then lifts the pallet, facilitating the transfer of material on top of the pallet. Although the conveying mechanism can transport the loading mechanism, it is prone to deviation during the conveying process, which is not conducive to the matching of the positioning mechanism and the loading mechanism, and is prone to deviation, affecting the transfer of materials. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a positioning mechanism for tooling plates of double-speed chain conveyors.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a positioning mechanism for a tooling plate of a high-speed chain conveyor, comprising two fixed support plates. Two conveying mechanisms are connected between the two fixed support plates via a spacing adjustment assembly. Each conveying mechanism has a limiting baffle on its outer side wall and a loading mechanism at its top. The spacing adjustment assembly includes a bidirectional reciprocating screw located between the two ends of the two fixed support plates and a guide slide rod located on one side of the bidirectional reciprocating screw. A stepper motor driving the bidirectional reciprocating screw is mounted on the fixed support plates. Movable seats are threaded onto both external threaded sections of the bidirectional reciprocating screw, and the conveying mechanisms are mounted on the movable seats. A mounting plate is located between the two fixed support plates. A vertically upward positioning baffle is located in the middle of the mounting plate. A distance sensor is mounted on the positioning baffle. A positioning assembly is located on the mounting plate. A through hole is provided on the movable seat for the mounting plate to pass through. A controller is mounted on the mounting plate.

[0007] As a preferred embodiment of the present invention, the conveying mechanism includes a mounting base located at the top of the movable seat, the top of the mounting base having a mounting groove, and a limiting baffle located on the outside of the mounting base.

[0008] As a preferred embodiment of this utility model, the mounting groove is provided with a driving block inside, and a conveyor chain is connected to the outside of the driving block.

[0009] As a preferred embodiment of this utility model, a drive motor for driving the drive block to rotate is installed on the mounting base.

[0010] As a preferred embodiment of this utility model, the positioning component includes an electric push rod installed vertically upward in the middle of the mounting plate, and a positioning block is provided at the top of the electric push rod.

[0011] As a preferred embodiment of the present invention, the loading mechanism includes a pallet, and the bottom end of the pallet is provided with a positioning support block that matches the positioning block.

[0012] As a preferred embodiment of this utility model, the positioning block is configured as a frustum, and the bottom end of the positioning support block is provided with a conical groove that matches the frustum.

[0013] As a preferred embodiment of this utility model, the bottom ends of the two fixed support plates are connected by multiple reinforcing connecting plates. The bottom end of the reinforcing connecting plate is provided with a support leg, and the end of the reinforcing connecting plate is provided with a reinforcing rib plate connected to the fixed support plate.

[0014] The beneficial effects of this utility model are:

[0015] This positioning mechanism for the tooling plate of the high-speed chain conveyor uses a limiting baffle on the outer wall of the conveying mechanism to prevent offset between the two conveying mechanisms and the loading mechanism during transport. This allows the loading mechanism to move along the middle of the two fixed support plates, avoiding the offset that occurs when the conveying mechanism directly transports the loading mechanism, which affects the positioning effect of the positioning component on the loading mechanism. This ensures the rotation of materials. Furthermore, the spacing adjustment component can adjust the distance between the two conveying mechanisms, making it adaptable to the transport of loading mechanisms of different specifications and improving its applicability. Specifically, when adjusting the distance between the two conveying mechanisms, the output shaft of the stepper motor drives the reciprocating screw to rotate. Under the guidance of the guide slide, the two external threaded sections of the reciprocating screw are respectively threaded to the two movable seats, causing the movable seats to move closer or further apart, thereby adjusting the distance between the two conveying mechanisms.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a positioning mechanism for a tooling plate of a double-speed chain conveyor, comprising two fixed support plates 1. Two conveying mechanisms 3 are connected between the two fixed support plates 1 via a spacing adjustment assembly 2. Each of the two conveying mechanisms 3 has a limiting baffle 4 on its outer side wall, and a loading mechanism 20 is provided at the top of each conveying mechanism 3. The spacing adjustment assembly 2 includes a bidirectional reciprocating screw 5 located between the two ends of the two fixed support plates 1 and a guide slide rod 6 located on one side of the bidirectional reciprocating screw 5. A stepper motor 7 is mounted on the fixed support plates 1 to drive the bidirectional reciprocating screw 5 to rotate. Movable seats 8 are threadedly connected to both external threaded sections of the bidirectional reciprocating screw 5, and the conveying mechanism 3 is located on the movable seats 8. A mounting plate 9 is provided between the two fixed support plates 1. A vertically upward positioning baffle 10 is provided in the middle of the mounting plate 9. A distance sensor 11 is mounted on the positioning baffle 10. A positioning assembly 12 is provided on the mounting plate 9. A through hole is provided on the movable seat 8 for the mounting plate 9 to pass through. A controller 27 is installed on the loading plate 9. By providing a limit baffle 4 on the outer wall of the conveying mechanism 3, the offset of the two conveying mechanisms 3 to the loading mechanism 20 during the conveying process can be avoided, so that the loading mechanism 20 moves along the middle of the two fixed support plates 1. This avoids the offset that occurs when the conveying mechanism 3 directly conveys the loading mechanism 20, which affects the positioning effect of the positioning component 12 on the loading mechanism 20. This ensures the rotation of materials. The spacing adjustment component 2 can adjust the distance between the two conveying mechanisms 3, so that it can be adapted to the conveying of loading mechanisms 20 of different specifications, thus improving applicability. When adjusting the distance between the two conveying mechanisms 3, the output shaft of the stepper motor 7 drives the reciprocating screw to rotate. Under the guidance of the guide slide 6, since the two external thread sections of the reciprocating screw are respectively threaded to the two movable seats 8, the movable seats 8 move closer or further apart, thereby adjusting the distance between the two conveying mechanisms 3.

[0025] Specifically, such as Figure 2 and Figure 4As shown, the conveying mechanism 3 includes a mounting base 13 located at the top of the movable seat 8. The top of the mounting base 13 has a mounting groove 14. A limiting baffle 4 is located on the outside of the mounting base 13. A drive block 15 is located inside the mounting groove 14. A conveying chain 16 is connected to the outside of the drive block 15. A drive motor 17 is mounted on the mounting base 13 to drive the drive block 15 to rotate. The output shaft of the drive motor 17 drives the conveying chain 16 through the drive block 15, thereby enabling the conveying of the loading mechanism 20.

[0026] Specifically, such as Figure 3 and Figure 5 As shown, the positioning component 12 includes an electric push rod 18 installed vertically upward in the middle of the mounting plate 9. The top of the electric push rod 18 is provided with a positioning block 19. The loading mechanism 20 includes a support plate 21. The bottom end of the support plate 21 is provided with a positioning support block 22 that matches the positioning block 19. The positioning block 19 is a truncated cone. The bottom end of the positioning support block 22 is provided with a conical groove 23 that matches the truncated cone. When the loading mechanism 20 moves to the point where it is about to come into contact with the distance sensor 11, the distance sensor 11 transmits the distance information to the controller 27. The controller 27 controls the electric push rod 18 to open. The output shaft of the electric push rod 18 pushes the positioning block 19 to move upward. The positioning block 19 matches the conical groove 23 of the positioning support block 22. The conical shape makes it easy for the positioning block 19 to enter the conical groove 23 of the positioning support block 22.

[0027] Specifically, such as Figure 2 As shown, the bottom ends of the two fixed support plates 1 are connected by multiple reinforcing connecting plates 24. The bottom end of the reinforcing connecting plate 24 is provided with a support leg 25, and the end of the reinforcing connecting plate 24 is provided with a reinforcing rib plate 26 connected to the fixed support plate 1. This can support the two fixed support plates 1 and provide high stability.

[0028] During operation, the positioning mechanism of this type of double-speed chain conveyor tooling plate, by providing a limiting baffle 4 on the outer wall of the conveying mechanism 3, can prevent the two conveying mechanisms 3 from deviating during the conveying of the loading mechanism 20, so that the loading mechanism 20 moves along the middle of the two fixed support plates 1. This avoids the deviation that occurs when the conveying mechanism 3 directly conveys the loading mechanism 20, which affects the positioning effect of the positioning component 12 on the loading mechanism 20, and ensures the rotation of materials. In addition, the setting of the spacing adjustment component 2 can adjust the distance between the two conveying mechanisms 3, so as to adapt to the conveying of loading mechanisms 20 of different specifications and improve applicability. When adjusting the distance between the two conveying mechanisms 3, the output shaft of the stepper motor 7 drives the reciprocating screw to rotate, and under the guidance of the guide slide 6, since the two external thread sections of the reciprocating screw are respectively threadedly connected to the two movable seats 8, the movable seats 8 move closer or further away from each other, thereby adjusting the distance between the two conveying mechanisms 3.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
