Description

Technical Field

[0001] This utility model relates to the technical field of aircraft tires, and in particular to a buffer positioning device for an aircraft radial tire forming machine. Background Technology

[0002] Aviation radial tires not only rotate at high speeds during operation, but also bear very large loads. Therefore, the variety and number of various rubber components that make up the tire are greater than those of ordinary land tires.

[0003] Existing buffer positioning devices for radial tire forming machines, such as the one disclosed in utility model patent application number 202222348057.3, mainly include a buffer component, a positioning cylinder placed on one side of the buffer component, a push plate hinged to the telescopic end of the positioning cylinder, a first fixing plate hinged to the side of the push plate away from the positioning cylinder, and a second fixing plate hinged to the side of the positioning cylinder away from the push plate. In use, when the tire forming machine's storage trolley moves close to the device, a protrusion under the storage trolley blocks the light emitted by a photoelectric switch. The photoelectric switch sends a signal to the PLC controller, which then outputs a signal to the solenoid valve, causing the piston rod of the positioning cylinder to extend.

[0004] However, most existing buffer positioning devices are inconvenient to adjust the parking position of the storage car, lack flexibility in use, and have small buffer and fixed areas. The same part is easily damaged by long-term stress, which affects the service life of the equipment. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a buffer positioning device for an aviation radial tire forming machine that not only uses rubber wheels on both sides to initially decelerate the storage car, but also increases the area of ​​the buffer plate to prevent the contact parts of the storage car from being broken for a long time. In addition, it can drive the storage car to move and make fine adjustments to the position of the storage car to ensure the accuracy of the feeding position.

[0006] This utility model discloses a buffer positioning device for an aircraft radial tire forming machine, including a worktable; it also includes two sets of limiting mechanisms, a buffer mechanism, a moving mechanism, and a fixing mechanism. The two sets of limiting mechanisms are installed on the worktable and limit the sides of the storage trolley. The buffer mechanism is installed on the worktable and buffers the storage trolley. The moving mechanism is installed on the worktable and drives the storage trolley to move. The fixing mechanism is installed on the moving mechanism and fixes the storage trolley. When the operator pushes the storage trolley onto the worktable, the two sets of limiting mechanisms position the left and right sides of the storage trolley. Under the action of inertia, the storage trolley hits the buffer mechanism and decelerates and stops. Then, the fixing mechanism fixes the bottom of the storage trolley. The moving mechanism drives the storage trolley to move back and forth through the fixing mechanism, making fine adjustments to the position of the storage trolley and improving the flexibility of the device.

[0007] Preferably, the workbench includes a base, a control box, a heat dissipation grille, two sets of wheel limit grooves, and a displacement detector. The base is installed on the work surface, the control box is installed on the base, the heat dissipation grille is installed on the base, both sets of wheel limit grooves are installed on the base, and the displacement detector is installed on the base. When the worker pushes the storage cart onto the base, the two sets of wheel limit grooves limit the universal wheels of the storage cart to prevent them from rotating. The displacement detector detects the position of the storage cart, and the control box processes the detection results to facilitate the control of the moving mechanism to drive the storage cart for fine-tuning. The heat dissipation grille facilitates heat dissipation for the control box and the moving mechanism.

[0008] Preferably, the limiting mechanism includes a side baffle, multiple sets of rubber rollers, a rotating shaft, an intercepting plate, and a pad. The side baffle is mounted on the base, and the multiple sets of rubber rollers are rotatably mounted on the side baffle. The rotating shaft is mounted on the side baffle, the intercepting plate is mounted on the rotating shaft, and the pad is mounted on the intercepting plate. The multiple sets of rubber rollers limit the two sides of the storage cart, and the rubber rollers have a high coefficient of friction, which can initially decelerate the storage cart. When the displacement detector detects that the storage cart has completely passed the intercepting plate, the control box starts the rotating shaft through an electrical signal. The rotating shaft drives the intercepting plate to rotate to a horizontal state, which facilitates limiting the rear end of the storage cart and prevents the storage cart from rebounding too much and moving out of the adjustable range of the moving mechanism. The pad is set to prevent the storage cart and the intercepting plate from colliding and breaking.

[0009] Preferably, the buffer mechanism includes two sets of shock absorbers, two sets of springs, and a buffer plate. Both sets of shock absorbers are installed inside the control box, both sets of springs are installed inside the control box, and the buffer plate is installed on the two sets of shock absorbers. When the storage car hits the buffer plate, the buffer plate compresses the two sets of shock absorbers and the two sets of springs to buffer the impact and prevent the storage car from directly colliding with the control box.

[0010] Preferably, the buffer plate is also made of high-damping polyurethane elastomer; when the high-damping polyurethane elastomer deforms, most of the energy is used to overcome the molecular friction inside the material and is converted into heat, and only a small portion of the energy is stored as elastic potential energy. Since the stored elastic potential energy is very small, the rebound force is very small, thus preventing the material storage vehicle from rebounding too far.

[0011] Preferably, the moving mechanism includes a lead screw box, a servo motor, a reducer, and a lead screw. The lead screw box is mounted on the base, the servo motor is mounted inside the control box, the reducer is mounted inside the control box, and the output end of the servo motor is connected to the input end of the reducer. The lead screw is rotatably mounted inside the lead screw box and is connected to the reducer for transmission. When the servo motor is started, the servo motor drives the lead screw to rotate through the reducer. The lead screw drives the fixed mechanism to move inside the lead screw box, which facilitates fine adjustment of the position of the storage cart.

[0012] Preferably, the fixing mechanism includes a slider, a hydraulic cylinder, and an electromagnetic chuck. The slider is slidably installed in the screw box and connected to the screw via a threaded drive. The bottom end of the hydraulic cylinder is connected to the top end of the slider, and the bottom end of the electromagnetic chuck is connected to the top end of the hydraulic cylinder. When it is necessary to fine-tune the position of the storage cart, the control box starts the hydraulic cylinder through an electrical signal. The hydraulic cylinder pushes the electromagnetic chuck to adhere to the bottom end of the storage cart, and the screw drives the slider to slide in the screw box, which facilitates the movement and fine-tuning of the storage cart.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the staff pushes the storage cart onto the workbench, two sets of limiting mechanisms position the left and right sides of the storage cart, the storage cart hits the buffer mechanism under inertia and slows down to stop, then the fixing mechanism fixes the bottom of the storage cart, and the moving mechanism drives the storage cart to move back and forth through the fixing mechanism to make fine adjustments to the position of the storage cart, thereby improving the flexibility of the device.

[0017] This utility model discloses a buffer positioning device for an aircraft radial tire forming machine, including a worktable 01; it also includes two sets of limiting mechanisms 02, a buffer mechanism 03, a moving mechanism 04, and a fixing mechanism 05. The two sets of limiting mechanisms 02 are installed on the worktable 01 and limit the sides of the storage trolley; the buffer mechanism 03 is installed on the worktable 01 and buffers the storage trolley; the moving mechanism 04 is installed on the worktable 01 and drives the storage trolley to move; the fixing mechanism 05 is installed on the moving mechanism 04 and fixes the storage trolley. The worktable 01 includes a base 11, a control box 12, a heat dissipation grille 13, two sets of wheel limiting grooves 14, and a displacement detector 15. The base 11 is installed on... On the working surface, the control box 12 is mounted on the base 11, the heat dissipation grille 13 is mounted on the base 11, both sets of wheel limiting grooves 14 are mounted on the base 11, and the displacement detector 15 is mounted on the base 11; the limiting mechanism 02 includes a side baffle 21, multiple sets of rubber rollers 22, a rotating shaft 23, an intercepting plate 24, and a pad 25.

Both sets of shock absorbers 31 are... Installed inside the control housing 12, both sets of springs 32 are installed inside the control housing 12, and the buffer plate 33 is installed on the two sets of shock absorbers 31; the buffer plate 33 is also made of high-damping polyurethane elastomer; during operation, firstly, the operator pushes the storage cart onto the base 11, and the two sets of wheel limiting grooves 14 limit the universal wheels of the storage cart to prevent them from rotating. The displacement detector 15 detects the position of the storage cart, and the control housing 12 processes the detection results to facilitate the control of the moving mechanism 04 to drive the storage cart for fine-tuning. The heat dissipation grille 13 facilitates heat dissipation for the control housing 12 and the moving mechanism 04. Multiple sets of rubber rollers 22 protect the sides of the storage cart. The rubber roller 22 has a high surface friction coefficient, which can initially decelerate the storage car. When the displacement detector 15 detects that the storage car has completely passed the interceptor plate 24, the control box 12 starts the rotating shaft 23 through an electrical signal. The rotating shaft 23 drives the interceptor plate 24 to rotate to a horizontal state, which facilitates the limit of the tail end of the storage car and prevents the storage car from moving out of the adjustable range of the moving mechanism 04 due to excessive rebound force. By setting the pad block 25, the collision between the storage car and the interceptor plate 24 is prevented from causing breakage. The storage car hits the buffer plate 33, and the buffer plate 33 squeezes the two sets of shock absorbers 31 and two sets of springs 32 to buffer the impact and prevent the storage car from directly colliding with the control box 12. Example 2

[0018] like Figures 1 to 5As shown, this utility model discloses a buffer positioning device for an aircraft radial tire forming machine, based on embodiment 1. The moving mechanism 04 includes a lead screw box 41, a servo motor 42, a reducer 43, and a lead screw 44. The lead screw box 41 is mounted on the base 11, the servo motor 42 is mounted inside the control box 12, the reducer 43 is mounted inside the control box 12, and the output end of the servo motor 42 is connected to the input end of the reducer 43. The lead screw 44 is rotatably mounted inside the lead screw box 41 and is connected to the reducer 43 for transmission. The fixing mechanism 05 includes a slider 51, a hydraulic cylinder 52, and an electromagnetic suction device. The disc 53 and slider 51 are slidably installed inside the lead screw box 41 and connected to the lead screw 44 via threaded transmission.

The displacement detector 15 detects the position of the storage cart, and the control box 12 processes the detection results to facilitate the control of the moving mechanism 04 to drive the storage cart for fine-tuning. A heat dissipation grille 13 facilitates heat dissipation for the control housing 12 and the moving mechanism 04. Multiple sets of rubber rollers 22 limit the movement of the storage cart on both sides. The rubber rollers 22 have a high coefficient of friction, which helps to initially decelerate the storage cart. When the displacement detector 15 detects that the storage cart has completely passed the interceptor plate 24, the control housing 12 starts the rotating shaft 23 via an electrical signal. The rotating shaft 23 drives the interceptor plate 24 to rotate to a horizontal position, facilitating the limiting of the rear end of the storage cart and preventing it from rebounding out of the adjustable range of the moving mechanism 04 due to excessive force. Pads 25 are also provided to prevent the storage cart from colliding with the interceptor plate. The collision between plates 24 causes breakage, and the storage car hits the buffer plate 33. The buffer plate 33 squeezes the two sets of shock absorbers 31 and two sets of springs 32 to buffer the impact and prevent the storage car from directly colliding with the control box 12. When it is necessary to fine-tune the position of the storage car, the control box 12 starts the hydraulic cylinder 52 through an electrical signal. The hydraulic cylinder 52 pushes the electromagnetic chuck 53 to attract the bottom of the storage car and starts the servo motor 42. The servo motor 42 drives the lead screw 44 to rotate through the reducer 43. The lead screw 44 drives the slider 51 to move in the lead screw box 41, which facilitates the fine-tuning of the position of the storage car.
