[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0019] like Figure 1-6 As shown, this utility model provides an auxiliary support for a centerless grinder, including a centerless grinder body 1, a rotating seat 3 installed at the bottom of the centerless grinder body 1, a bottom support frame 2 rotatably connected to the bottom of the rotating seat 3, a plurality of connecting pipes 4 distributed in a circular pattern on the bottom support frame 2, and a foot pedal component 5 provided above the bottom support frame 2 for supporting the operator to stand and temporarily brace against the centerless grinder body 1, the bottom of the foot pedal component 5 engaging with a plurality of adjacent connecting pipes 4.

[0020] In this embodiment, the bottom support frame 2 includes an annular outer frame 21, and an inner support seat 22 is installed on the inner ring of the annular outer frame 21. A first engagement groove 24 is provided on the inner support seat 22. The rotating seat 3 includes a main seat body 31, and a second limiting block 32 is installed on the main seat body 31. The inner support seat 22 and the main seat body 31 engage with each other, and the second limiting block 32 is located inside the first engagement groove 24. A first limiting block 25 is provided inside the first engagement groove 24 to cooperate with the second limiting block 32 to limit the excessive rotation of the centerless grinding machine body 1.

[0021] In this embodiment, a second engagement groove 33 is provided on the main body 31. A plurality of balls 23 are arranged between the second engagement groove 33 and the annular outer frame 21. The balls 23 and the second engagement groove 33 provide stability for the rotation of the main body 31 on the inner support 22. Since there is a power supply for the centerless grinder body 1, if the centerless grinder body 1 rotates more than one revolution, the power cord will become tangled. Therefore, a first limiting block 25 in the first engagement groove 24 cooperates with the second limiting block 32, which allows the main body 31 to drive the centerless grinder body 1 to rotate only one revolution, effectively preventing the power cord from becoming tangled.

[0022] In this embodiment, the connecting pipe 4 includes a main body 41, a positioning block 43 is installed on the main body 41, a positioning screw 42 is threadedly connected to the positioning block 43, and the main body 41 is connected to the pedal assembly 5 through the positioning screw 42.

[0023] In this embodiment, the pedal assembly 5 includes a pedal 51, and four threaded cylinders 52 are rotatably connected to the bottom of the pedal 51. The bottom of each of the four threaded cylinders 52 is threaded with a connecting screw 53, and the bottom ends of the four connecting screws 53 are inserted into the interior of the adjacent main body 41. The four positioning screws 42 have a T-shaped cross-section when viewed from above. The pedal 51 can be raised or lowered by simply rotating the four threaded cylinders 52. It can be adjusted to the corresponding height as needed. When the position of the centerless grinder body 1 needs to be adjusted again, the pedal assembly 5 can be removed by rotating the multiple positioning screws 42, and then the centerless grinder body 1 can be rotated again. The operation is convenient and quick, and the T-shaped design is also convenient.

[0024] In this embodiment, the foot pedal 51 is in contact with the surface of the adjacent centerless grinder body 1, and an anti-slip pad 54 is installed on the top of the foot pedal 51. The foot pedal 51 can limit the deflection of the centerless grinder body 1 and make it stable and fixed.

[0025] In this embodiment, a plurality of circumferentially distributed rubber pads 26 are installed at the bottom of the annular outer frame 21, and a steel support ring 27 is installed at the bottom of the inner support seat 22. The thickness of the rubber pads 26 is greater than the thickness of the steel support ring 27. The double-layer support makes the thickness of the soft support greater than that of the hard support, which can ensure that the overall support is stable and slightly reduce the impact of vibration on the centerless grinder body 1.

[0026] The usage and working principle of this device are as follows: When using this device, first fix the bottom of the centerless grinder body 1 to the rotating seat 3, then place the rotating seat 3 on the bottom support frame 2. Then, rotate the centerless grinder body 1 to a suitable working angle and convenient for loading and unloading materials as needed. At this time, insert the bottom of the connecting screws 53 on the multiple threaded cylinders 52 at the bottom of the foot pedal 51 into the corresponding main body 41. Then, rotate the positioning screws 42 on the positioning block 43 to make the positioning screws 42 and the connecting screws 53 fit and fix together. After all four connecting screws 53 are fixed by the adjacent positioning screws 42, the connection between the bottom support frame 2 and the foot pedal assembly 5 can be established through the connecting pipe 4. When the foot pedal assembly 5 is fixed to the connecting pipe 4, the centerless grinder body 1 is just engaged with the foot pedal assembly 5, that is, the centerless grinder body 1 cannot move at this time, and can operate stably. During rotation, the ball bearing 23 and the second engagement groove 33 provide stability for the main body 31 to rotate on the inner support seat 22. Because of the power supply of the centerless grinder body 1, if the centerless grinder body 1 rotates more than one revolution, the power cord will become tangled. Therefore, the first limiting block 25 in the first engagement groove 24 cooperates with the second limiting block 32 to allow the main body 31 to drive the centerless grinder body 1 to rotate only one revolution, effectively preventing the power cord from becoming tangled. Furthermore, at the bottom of the annular outer frame 21, while the rubber pad 26 forms the bottom support of the annular outer frame 21, the inner steel support ring 27 will cooperate with the rubber pad 26 to provide auxiliary support. When a person steps on the foot pedal component 5, the rubber pad 26 will be slightly compressed and will work together with the steel support ring 27 to support the bottom of the bottom support frame 2, so that the bottom of the bottom support frame 2 has a larger contact area with the ground than the bottom of the centerless grinder body 1, thereby increasing the overall stability. When used by people of different heights, simply rotate the four threaded cylinders 52 to raise or lower the pedal 51, adjusting it to the required height. When the position of the centerless grinder body 1 needs to be adjusted again, simply rotate the multiple positioning screws 42 to remove the pedal assembly 5, and then rotate the centerless grinder body 1 again. The operation is convenient and quick.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
