Description

Technical Field

[0001] This utility model belongs to the field of tire installation equipment, and specifically relates to a PU foam tire installation clamp. Background Technology

[0002] Currently, PU foam tires have advantages such as being lightweight, shock-absorbing, and wear-resistant, and are widely used in electric vehicles, fitness equipment, medical devices, and other fields.

[0003] Because PU foam tires are made of a relatively soft material, traditional tire mounting clamps can easily cause damage to the tires during installation, such as compression deformation and surface scratches, affecting the tire's performance and appearance. At the same time, traditional clamps have poor versatility and cannot be quickly adjusted according to different installation positions, resulting in low installation efficiency and cumbersome operation. Therefore, there is an urgent need for a mounting clamp that can adapt to different specifications of PU foam tires and protect the tires from damage during installation.

[0004] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a PU foam tire mounting clamp to solve the problems of traditional tire mounting clamps causing damage to the tire during installation, such as squeezing deformation and surface scratches, which affect the tire's performance and appearance quality. At the same time, traditional clamps have poor versatility, cannot be quickly adjusted according to different installation positions, and have low installation efficiency and cumbersome operation. Utility Model Content

[0005] This utility model proposes a PU foam tire mounting clamp, which solves the problems of traditional tire mounting clamps in the prior art that easily cause damage to the tire during the installation process, such as squeezing deformation and surface scratches, affecting the tire's performance and appearance quality. At the same time, traditional clamps have poor versatility, cannot be quickly adjusted according to different installation positions, and have low installation efficiency and cumbersome operation.

[0006] The technical solution of this utility model is implemented as follows: a PU foam tire mounting fixture includes: a frame mechanism, a guide rail assembly is fixedly connected to the inner side of the frame mechanism, a transverse groove is opened inside the guide rail assembly, and a servo motor A is fixedly connected to the right end face of the guide rail assembly.

[0007] A transmission screw is mounted on the left output shaft of the servo motor A via a coupling. The servo motor A and the transmission screw together form a power output structure. A transverse groove is provided inside the guide rail assembly, and a displacement component is installed inside this groove. The displacement component has a screw hole that matches the transmission screw, and the servo motor B is fixedly connected inside the displacement component.

[0008] In a preferred embodiment, four casters are installed on the bottom surface of the frame mechanism. The four casters are fixedly connected to the four corners of the bottom surface of the frame mechanism, and the frame mechanism and the casters together form a movable structure.

[0009] In a preferred embodiment, a support push rod is fixedly connected to the bottom end face of the guide rail assembly. There are two support push rods, and the two support push rods are fixedly connected to the left and right sides of the bottom end face of the frame mechanism in a linear array.

[0010] In a preferred embodiment, support pads are fixedly connected to the bottom surfaces of both support push rods. The support pads and support push rods together form a pushing structure, and two slider assemblies are fixedly connected to the outer sides of the displacement assembly in opposite directions.

[0011] In a preferred embodiment, the displacement component is slidably connected to the inner side of the guide rail component via a slider component, and a bracket mechanism is mounted on the top output shaft of the servo motor B.

[0012] In a preferred embodiment, the main body of the bracket mechanism is a U-shaped structure with a one-way opening at the top, and a longitudinal groove is provided inside the bracket mechanism. An unfolding push rod is fixedly connected to the top surface of the transverse component in the bracket mechanism.

[0013] In a preferred embodiment, a bracket assembly is fixedly connected to the top of the unfolding push rod.

An arc-shaped slot assembly is opened inside the arc-shaped top surface of the bracket assembly, and a foaming wheel is embedded inside the slot assembly.

[0014] After using the above technical solution, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the power structure composed of the guide rail assembly, servo motor A and transmission screw on the inner side of the frame mechanism drives the displacement component to move along the transverse groove, and cooperates with the servo motor B to drive the bracket mechanism to rotate, so as to realize the position adjustment of the foaming wheel in the horizontal and vertical directions. This solves the problem of poor versatility and inability to quickly adjust the installation position of traditional clamps, and can adapt to the needs of different installation scenarios, thereby improving installation efficiency.

[0016] 2. In this utility model, the bracket assembly is moved up and down by the unfolding push rod in the bracket mechanism. The arc-shaped structure and the slot assembly of the bracket assembly fix the foam wheel, avoiding tire compression and deformation during installation.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-6 As shown, a PU foam tire mounting fixture includes: a frame mechanism 1, a guide rail assembly 1011 fixedly connected to the inner side of the frame mechanism 1, a transverse groove opened inside the guide rail assembly 1011, and a servo motor A2 fixedly connected to the right end face of the guide rail assembly 1011.

[0027] A transmission screw 201 is mounted on the left output shaft of servo motor A2 via a coupling. Servo motor A2 and transmission screw 201 together form a power output structure. A transverse groove is provided inside the guide rail assembly 1011. A displacement assembly 2011 is installed inside the transverse groove. A screw hole matching the transmission screw 201 is provided inside the displacement assembly 2011. A servo motor B2013 is fixedly connected inside the displacement assembly 2011.

[0028] Among them, the bottom end face of the frame mechanism 1 is equipped with four casters 101. The four casters 101 are fixedly connected to the four corners of the bottom end face of the frame mechanism 1. The frame mechanism 1 and the casters 101 together form a moving structure. The bottom end face of the guide rail assembly 1011 is fixedly connected with two support push rods 1012. The two support push rods 1012 are fixedly connected to the left and right sides of the bottom end face of the frame mechanism 1 in a straight line array.

[0029] Among them, support pads 1013 are fixedly connected to the bottom end surfaces of the two support push rods 1012. The support pads 1013 and the support push rods 1012 together form a pushing structure. Two slider assemblies 2012 are fixedly connected to the outer side of the displacement assembly 2011 in opposite directions. The displacement assembly 2011 is slidably connected to the inner side of the guide rail assembly 1011 through the slider assemblies 2012. A bracket mechanism 3 is installed on the top output shaft of the servo motor B2013.

[0030] The main body of the bracket mechanism 3 is a U-shaped structure with a one-way opening at the top, and a longitudinal groove is provided inside the bracket mechanism 3. An unfolding push rod 301 is fixedly connected to the top surface of the transverse component in the bracket mechanism 3. A bracket assembly 3011 is fixedly connected to the top of the unfolding push rod 301. The bracket assembly 3011 has an arc-shaped structure at the top, and two guide block assemblies 3012 with protruding structures are fixedly connected to the outer side of the bracket assembly 3011 in opposite directions. An arc-shaped slot assembly 3013 is provided inside the arc-shaped surface at the top of the bracket assembly 3011, and a foaming wheel 3014 is embedded inside the slot assembly 3013.

[0031] In use, the clamp is moved to the installation position by the casters 101 at the four corners of the bottom of the frame mechanism 1. Then, the support push rod 1012 is activated, and the support pad 1013 at its bottom contacts the ground and supports the frame mechanism 1, so that the casters 101 are lifted off the ground and the clamp is stably fixed.

[0032] Then, the foaming wheel 3014 is placed in the slot assembly 3013 at the top of the bracket assembly 3011, and the guide block assembly 3012 on the outside of the bracket assembly 3011 slides into the longitudinal groove inside the bracket mechanism 3; the unfolding push rod 301 is activated, which pushes the bracket assembly 3011 to move upward along the longitudinal groove, so that the foaming wheel 3014 is raised to a suitable height;

[0033] Then, start the servo motor A2. Its output shaft drives the transmission screw 201 to rotate through the coupling. The screw hole inside the displacement component 2011 that matches the transmission screw 201 causes it to move along the transverse groove of the guide rail component 1011. The slider component 2012 on the outside of the displacement component 2011 slides inside the guide rail component 1011 to ensure smooth movement. After the displacement component 2011 moves to the target position, start the servo motor B2013. Its output shaft drives the bracket mechanism 3 to rotate, so that the foaming wheel 3014 is aligned with the wheel hub installation position, and the tire installation operation can be performed.

[0034] During installation, the arc-shaped structure of the bracket assembly 3011 fits the foam wheel 3014, the slot assembly 3013 restricts tire displacement, the guide block assembly 3012 ensures the stability of the bracket assembly 3011 moving up and down, and the support push rod 1012 and the support pad 1013 maintain the stability of the frame mechanism 1 to prevent the clamp from shaking during installation. After installation, the components are operated in reverse order to remove the foam wheel 3014 and move the clamp to the designated location for storage.
