Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to an automatic assembly machine for model car gearbox wheels. Background Technology

[0002] The assembly of tires and gearbox components for existing car models usually requires manual assembly using tooling fixtures. This assembly method is inefficient and involves high labor intensity for workers. Utility Model Content

[0003] Based on this, the purpose of this utility model embodiment is to provide an automatic assembly machine for model car gearbox wheels, which can replace manual labor to achieve automated production and improve production efficiency.

[0004] An automatic assembly machine for model car gearbox wheels includes a feeding and positioning mechanism and a wheel forming mechanism;

[0005] The feeding and positioning mechanism includes a feeding wheel, a pressure rod, a feeding wheel drive device, and a pressure rod drive device. The pressure rod and the feeding wheel are located on the same plane. The feeding wheel has several grooves on its circumference for receiving the gear box. The feeding wheel drive device drives the feeding wheel to rotate around the center. The pressure rod drive device drives the pressure rod to engage and disengage from the feeding wheel. One end of the pressure rod has a limiting groove for covering the grooves and restricting the movement of the gear box.

[0006] The wheel forming mechanism consists of two sets. Each set includes a wheel receiving groove, a wheel feeding rod, and a wheel feeding drive device. The two sets of wheel forming mechanisms are symmetrically arranged on both sides of the feeding and positioning mechanism. The two sets of wheel feeding rods are coaxial, and their axes pass through the groove of the feeding wheel. The wheel receiving groove is located below the wheel feeding rod and is used to temporarily support the wheel. The wheel feeding drive device is used to drive the wheel feeding rod to move linearly along the axial direction of the wheel receiving groove, so that the wheel is threaded into both sides of the gearbox.

[0007] When the gearbox enters the groove of the feeding wheel, the feeding wheel rotates around the center, rotating the groove that receives the gearbox to below the pressure rod. The pressure rod closes with the groove, and the limiting groove of the pressure rod covers the groove, restricting the movement of the gearbox. At this time, the gearbox is located at the axis of the two sets of feeding wheel top rods. The feeding wheel drive device drives the feeding wheel top rod to insert the wheels into both sides of the gearbox, completing the automatic assembly of the gearbox wheels.

[0008] As a preferred embodiment, several of the grooves are arranged at equal angles along the circumference of the feeding wheel.

[0009] As a preferred embodiment, the surface of the feeding wheel is provided with a plurality of positioning holes at equal angles, and the feeding positioning mechanism further includes a positioning cylinder, which can pass through the positioning holes and fix the feeding wheel. The positioning holes can accurately position the feeding wheel, and further fix the feeding wheel when the wheel enters the gearbox.

[0010] As a preferred embodiment, the wheel receiving groove is a U-shaped groove or a V-shaped groove. When the wheel contacts the V-shaped groove, there are two tangential surfaces, generating moderate and uniform friction, preventing the wheel from tilting to one side, and facilitating the wheel's insertion into the gearbox.

[0011] As a preferred embodiment, each set of the wheel forming mechanism further includes a wheel feeding groove, which is connected to the wheel receiving groove. The wheel feeding groove can continuously feed wheels into the wheel receiving groove.

[0012] As a preferred embodiment, each set of the wheel forming mechanism further includes a wheel entry detection device and a limiting clamp. The wheel entry detection device is located on the side of the wheel receiving groove and is used to detect whether the wheel has entered the wheel receiving groove. The limiting clamp is connected to the wheel feeding groove and is used to limit the number of wheels entering the wheel receiving groove.

[0013] As a preferred embodiment, an automatic assembly machine for model car gearbox wheels further includes a main frame, on which the feeding and positioning mechanism and the wheel forming mechanism are fixed. The main frame is equipped with a finished product discharge port, a discharge chute, a circuit control system, and a function control panel. The finished product discharge port is located between the two sets of wheel forming mechanisms and below the feeding wheel. The discharge chute is connected to the finished product discharge port and is used to convey the finished product out of the main frame. After the gearbox and wheels are assembled, the pressure rod leaves the groove of the feeding wheel. As the feeding wheel rotates, the assembled finished product falls into the finished product discharge port, is collected there, and is then conveyed out of the main frame via the discharge chute. The function control panel is used to adjust the parameter settings of each device, and the circuit control system is used to control the switching of each device.

[0014] As a preferred embodiment, an automatic assembly machine for model car gearboxes and wheels further includes a gearbox feeding and screening device and a wheel feeding and screening device. The output end of the gearbox feeding and screening device is connected to the feeding wheel, and the output end of the wheel feeding and screening device is connected to two sets of wheel feeding grooves. Both the gearbox feeding and screening devices are funnel-shaped and equipped with screening tracks. A vibration generator is also provided at the bottom of the gearbox feeding and screening device. The screening tracks allow gearboxes or wheels with incorrect shapes to fall into the funnel. Under the action of the vibration generator, the gearbox feeding and screening device can also gradually raise the gearboxes through vibration, pushing them along irregular screening tracks (with special obstacles set at certain positions according to the product's shape to identify products in the correct orientation), allowing gearboxes that meet the orientation requirements to be fed into the feeding wheel.

[0015] As a preferred embodiment, the pressure rod is a lever structure, with the pressure rod driving device and the limiting groove respectively connected to both ends. The pressure rod driving device and the feed wheel driving device are cylinders. Attached Figure Description

Detailed Implementation

[0021] In the description of the embodiments of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figures 1-3 As shown, an automatic assembly machine for model car gearbox wheels includes a feeding and positioning mechanism 1, a wheel forming mechanism 2, a main frame 3, an axle feeding and screening device 4, and a wheel feeding and screening device 5.

[0023] The feeding and positioning mechanism 1 includes a feeding wheel 11, a pressure lever 12, a feeding wheel drive device, a pressure cylinder 13, and a positioning cylinder 14. The pressure lever 12 and the feeding wheel 11 are located on the same vertical plane. The feeding wheel 11 has six grooves 111 at equal angles on its circumference for receiving the gear box. The feeding wheel drive device is used to drive the feeding wheel 11 to rotate around the center. One end of the pressure lever 12 has a limiting groove 121, and the other end is connected to the pressure cylinder 13. The pressure cylinder 13 is used to drive the pressure lever 12 to engage and disengage the feeding wheel 11. The surface of the feeding wheel 11 has positioning holes 112 at equal angles. The positioning cylinder 14 can pass through the positioning holes 112 to position and fix the rotation position of the feeding wheel 11, so that the limiting groove 121 accurately covers the groove 111 and restricts the movement of the gear box.

[0024] There are two sets of wheel forming mechanisms 2. Each set of wheel forming mechanisms 2 includes a wheel receiving groove 21, a wheel feeding cylinder 22, a wheel feeding top rod 23, a wheel feeding groove 24, a wheel entry detection device 25, and a limiting clamp 26. The two sets of wheel forming mechanisms 2 are symmetrically arranged on both sides of the feeding and positioning mechanism 1. The two sets of wheel feeding top rods 23 are coaxial, and their axes pass through the highest point of the feeding wheel 11. The cross-sectional area of ​​the wheel feeding top rod 23 is not less than half of the cross-sectional area of ​​the wheel, so as to keep the force even when pushing the wheel. The wheel receiving groove 21 is located below the wheel feeding top rod 23 and is used to temporarily support the wheel. The wheel feeding groove 24 is connected to the wheel receiving groove 21. The wheel entry detection device 25 is located on the side of the wheel receiving groove 21. The limiting clamp 26 is connected to the wheel feeding groove 24. The limiting clamp 26 is used to limit the number of wheels entering the wheel receiving groove 21 from the wheel feeding groove 24. The wheel entry detection device 25 detects whether the wheel has entered the wheel receiving groove 21. Specifically, the wheel receiving groove 31 can be a U-shaped groove or a V-shaped groove. In this utility model, a V-shaped groove is selected. When the wheel contacts the V-shaped groove, there will be two tangential surfaces, which will generate a moderate and uniform friction force, prevent the wheel from tilting to the side, and facilitate the wheel to be pushed into the gearbox.

[0025] The feeding and positioning mechanism 1 and the cascading wheel forming mechanism 2 are fixed on the main frame 3. The main frame 3 is equipped with a finished product discharge port 31, a feeding trough 32, a function control panel 33, and a circuit control system. The finished product discharge port 31 is located between the two sets of cascading wheel forming mechanisms 2 and below the feeding wheel 11. The feeding trough 32 is connected to the finished product discharge port 31 and is used to convey the finished product out of the main frame 3. The function control panel is used to adjust the parameter settings of each device, and the circuit control system is used to control the switching of each device.

[0026] The output end of the tooth box feeding and screening device 4 is connected to the feeding wheel 11. The bottom of the tooth box feeding and screening device 4 is equipped with a vibration generator. The output end of the wheel feeding and screening device 5 is connected to the two sets of wheel feeding troughs 24 respectively. The tooth box feeding and screening device 4 and the wheel feeding and screening device 5 are funnel-shaped. Both the tooth box feeding and screening device 4 and the wheel feeding and screening device 5 are equipped with screening tracks.

[0027] The working principle of this utility model is as follows: The parameter settings of each device are adjusted through the function control panel 33, and the circuit control system controls the switching of each device. After the debugging is completed, the tooth box feeding and screening device 4, under the action of the vibration generator, causes the tooth box to rise gradually through the vibration principle, pushing the tooth box along the irregular screening track, and sending the tooth box that meets the orientation requirements into the feeding wheel 11; the wheel feeding and screening device 5 screens out the wheels that meet the shape requirements through the screening track and sends them into the wheel feeding groove 24. Tooth boxes and wheels that do not meet the shape or orientation requirements fall into the funnel.

[0028] When the gearbox enters the groove 111 of the feeding wheel 11, the feeding wheel 11 rotates around the center, driving the gearbox to the axis of the two sets of feeding wheel push rods 23. The feeding wheel 11 stops rotating, and then the positioning cylinder 14 passes through the positioning hole 112 to position and fix the position of the feeding wheel 11. Under the drive of the pressure cylinder 13, the pressure lever 12 closes with the feeding wheel 11, and the limiting groove 121 of the pressure lever 12 precisely covers the groove 111, restricting the movement of the gearbox.

[0029] When a wheel enters the wheel receiving groove 21 from the wheel feeding groove 24, the wheel entry detection device 25 detects whether the wheel has entered the wheel receiving groove 21, and the limiting clamp 26 limits the number of wheels entering the wheel receiving groove 21. When the pressure lever 12 and the feeding wheel 11 are closed, the feeding wheel cylinder 22 drives the feeding wheel push rod 23 to move in a straight line, inserting the wheel into both sides of the gearbox, completing the assembly of the gearbox wheel. After assembly, the feeding wheel cylinder 22 drives the feeding wheel push rod 23 to reset, the pressure lever 13 drives the pressure lever 12 to leave the feeding wheel 11, the positioning cylinder 14 leaves the positioning hole 112, the feeding wheel 11 rotates around the center, and the assembled finished product falls into the finished product discharge port 31 under the action of gravity as the feeding wheel 11 rotates, and is then collected and transported out of the main frame 3 by the discharge trough 32, completing the collection of the finished product.

[0030] The above embodiments illustrate only one implementation of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present utility model, and these all fall within the protection scope of the present utility model.
