Description

Technical Field

[0001] This application relates to the field of grinding machines, and more particularly to a guardrail grinding device. Background Technology

[0002] Grinding machines are devices used for precision machining and surface polishing in the mold industry. They are often used to grind the surface of guardrails. When grinding guardrails, a conventional grinding machine is connected to the power supply, and the grinding disc at one end of the machine rotates at high speed. The user operates the grinding disc by holding the handle on the surface of the machine to perform precision machining and polishing.

[0003] Regarding the aforementioned technologies, the inventors believe that when users polish guardrails, due to the smooth surface of the guardrails, it is easy for the polishing disc to be difficult to fit against the guardrail surface when using a polishing machine. As a result, it takes a long time and effort for the staff to adjust the polishing disc.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the inconvenience of using grinding machines to polish guardrail surfaces, this application provides a guardrail polishing device.

[0006] The guardrail grinding device provided in this application adopts the following technical solution:

[0007] A guardrail polishing device includes a body and a connecting ring. A polishing disc is rotatably mounted on one end of the body, and a handle is fixedly connected to the other end of the body. A connecting block is fixedly mounted on one end of the connecting ring. A rotating frame is rotatably connected to the surface of the connecting block. A slider is slidably mounted on the inner wall of the rotating frame. A threaded rod is welded to one end of the slider. A fixed frame is rotatably connected to one end of the threaded rod via a bearing. Two rotating rollers are rotatably mounted on the inner wall of the fixed frame. The inner ring wall of the connecting ring is fixedly connected to the surface of the handle. The fixed frame has a U-shaped cross-section, and the fixed frame and the rotating frame are arranged perpendicular to each other. The two rotating rollers are symmetrically distributed about the polishing disc.

[0008] Preferably, the dimensions of the slider surface are adapted to the dimensions of the inner wall of the rotating frame, and a spring is fixedly installed at one end of the slider, and a fixing block is fixedly connected to the end of the spring away from the slider, and one end of the fixing block is fixedly installed on the surface of the rotating frame.

[0009] Preferably, a limiting ring is threaded onto the surface of the threaded rod, and one end of the limiting ring is engaged with the surface of the fixing frame.

[0010] Preferably, the dimensions of the connecting block surface are compatible with the dimensions of the rotating frame surface, and a locking block is fixedly connected to one end of the connecting block, the surface of which engages with the inner wall of the rotating frame.

[0011] Preferably, the inner wall of the card block is fixedly connected with bolts, and the surface of the bolts is fixedly installed with the inner wall of the rotating frame.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. By installing a connecting ring on the handle surface, a rotating frame is mounted on one end of the connecting ring via a connecting block. A threaded rod is slidably connected to the inner wall of the rotating frame via a slider. Two rotating rollers are mounted on one end of the threaded rod via a fixed frame to connect the rotating rollers to the guardrail surface, thus facilitating the positioning of the grinding disc. A spring is mounted on one end of the slider, and the spring is mounted on the rotating frame surface via a fixed block to pull the slider, thereby keeping the rotating rollers in contact with the guardrail surface. A limit ring is threaded onto the surface of the threaded rod, and the rotating limit ring engages with the surface of the fixed frame to adjust and fix the angle of the fixed frame, facilitating the contact of the rotating rollers on the inner wall of the fixed frame with guardrails at different angles. Compared with existing technologies, this significantly improves the ease of use of the grinding machine.

[0014] 2. Alternatively, a connecting block can be installed at one end of the connecting ring, with the surface of the connecting block rotatably connected to one end of the rotating frame to facilitate rotation of the rotating frame and easy retraction of the rotating roller when not in use. The locking block at one end of the connecting block is connected to the inner wall of the rotating frame, and bolts are passed through the connecting block and the locking block for fixation, so that the rotating frame can be installed at one end of the connecting block; effectively reducing the impact of the device on the grinder.

The connecting ring 4 is installed on the surface of the handle 3. A rotating frame 5 is installed on one end of the connecting ring 4 through the connecting block 13. A slider 6 is slidably installed on the inner wall of the rotating frame 5. A threaded rod 7 is connected to one end of the slider 6. A fixed frame 8 is rotatably connected to one end of the threaded rod 7 through the bearing. Two rotating rollers 9 are rotatably installed on the inner wall of the fixed frame 8. The rotating rollers 9 are slidably connected to the surface of the guardrail, thereby facilitating the positioning of the polishing disc 2.

[0022] Reference Figure 2 A spring 11 is installed at one end of the slider 6. The spring 11 is installed on the surface of the rotating frame 5 by means of the fixing block 12. The spring 11 pulls the slider 6, thereby keeping the rotating roller 9 in contact with the surface of the guardrail, so that the grinding disc 2 can be used to grind the surface of the guardrail. A limit ring 10 is installed on the threaded surface of the threaded rod 7. The rotating limit ring 10 is engaged with the surface of the fixing frame 8, thereby adjusting and fixing the angle of the fixing frame 8, so that the rotating roller 9 on the inner wall of the fixing frame 8 can be in contact with the guardrail at different angles.

[0023] Reference Figure 3 - Figure 4 The connecting block 13 is installed at one end of the connecting ring 4. The surface of the connecting block 13 is rotatably connected to one end of the rotating frame 5, so as to facilitate the rotation of the rotating frame 5. When positioning is not required, the rotating roller 9 can be retracted to facilitate the grinding disc 2 to grind the surface of the guardrail. A locking block 14 is installed at one end of the connecting block 13. The locking block 14 is connected to the inner wall of the rotating frame 5, and the bolt 15 is passed through the connecting block 13 and fixed to the locking block 14, so that the rotating frame 5 is installed at one end of the connecting block 13.

A spring 11 is installed on one end of the slider 6. The spring 11 is installed on the surface of the rotating frame 5 through a fixed block 12, so as to pull the slider 6 with the spring 11, thereby keeping the rotating rollers 9 in contact with the guardrail surface. A limiting ring 10 is threaded on the surface of the threaded rod 7. The rotating limiting ring 10 is engaged with the surface of the fixed frame 8, so as to adjust and fix the angle of the fixed frame 8, and facilitate the contact of the rotating rollers 9 on the inner wall of the fixed frame 8 with the guardrail at different angles.

[0025] Alternatively, the connecting block 13 can be installed at one end of the connecting ring 4. The surface of the connecting block 13 is rotatably connected to one end of the rotating frame 5 so that the rotating frame 5 can be rotated and the rotating roller 9 can be retracted when not in use.
