[0027] Example 1

[0028] See Figures 1 to 7 A mobile rotary surface grinding machine includes a mobile trolley 1, a ground rail 2, a mobile seat 3, a rotating seat 4, a telescopic assembly 5, and a grinding head 6. The mobile trolley 1 is connected to the ground rail 2, the mobile seat 3 is connected to the trolley, the rotating seat 4 is connected to the mobile seat 3, the telescopic assembly 5 is connected to the rotating seat 4, and the grinding head 6 is connected to the telescopic assembly 5. The rotation and movement of the grinding head 6 can be realized through the cooperation of the mobile trolley 1, the telescopic assembly 5, and the rotating seat 4.

[0029] like Figure 5 and Figure 6 As shown, the ground rail 2 includes an upper rail 21 and a lower rail 22, and the wheel surface of the mobile trolley 1 is V-shaped, with the wheel engaged between the upper rail 21 and the lower rail 22.

[0030] like Figure 1 and Figure 4 As shown, the ground rail 2 is provided with a movable positioning hole 23, and the trolley is provided with a movable positioning pin 24. The movable positioning holes 23 are arranged in an array.

[0031] like Figure 1 and Figure 7 As shown, the movable seat 3 is provided with a steering positioning hole 31 on the side near the rotating seat 4, and the rotating seat 4 is provided with a steering positioning pin 41, and the steering positioning holes 31 are arranged in an array.

[0032] like Figures 1 to 3 As shown, the telescopic assembly 5 includes a fixed seat 51, a movable seat 52, a lead screw 53, and a ball bearing slider 54. The fixed seat 51 is connected to the rotating seat 4. The movable seat 52 is slidably connected to the fixed seat 51. The lead screw 53 is mounted on the fixed seat 51 through a bracket. The ball bearing slider 54 is connected to the movable seat 52 through a bracket and is connected to the lead screw 53.

[0033] like Figure 1 and Figure 2 As shown, the lead screw 53 is driven by a rotary motor 511, which is connected to the side of the fixed base 51 away from the grinding head 6 in the length direction via a flange.

[0034] like Figure 1 As shown, a mounting base 62 is provided between the grinding head 6 and the telescopic component 5. The grinding head 6 is connected to the mounting base 62, and a drive motor 61 is connected to the mounting base 62. The grinding head 6 is driven by the drive motor 61.

[0035] Working principle

[0036] Mobile rotary surface grinding machines achieve flexible and stable surface grinding operations through the coordinated operation of multiple components. Their core principle is to adapt to the grinding needs of different work positions and directions by organically combining movement adjustment, rotation and steering, telescopic positioning and power drive.

[0037] The equipment achieves linear position adjustment through the cooperation of the mobile trolley 1 and the ground rail 2. The ground rail 2 consists of an upper rail 21 and a lower rail 22. The V-shaped wheels of the mobile trolley 1 are engaged between the two rails. The fit between the V-shaped structure and the rail prevents derailment during movement and ensures the stability of linear operation. The array of movable positioning holes 23 on the ground rail 2 cooperates with the movable positioning pins 24 on the trolley. When the trolley moves to the target position, the pins are inserted into the corresponding positioning holes to achieve temporary rigid fixation and prevent positional deviation during operation.

[0038] The rotational connection between the rotating base 4 and the movable base 3 enables the directional adjustment of the grinding head 6. The array of steering positioning holes 31 on the movable base 3 engages with the steering positioning pins 41 on the rotating base 4. When the rotating base 4 drives the grinding head 6 to rotate to the target angle (e.g., corresponding to different production line directions), the pins insert into the positioning holes to fix the angle, ensuring the stability of the grinding head 6 during regrinding. This design allows a single unit to switch to different operating directions, adapting to multiple production lines.

[0039] The telescopic assembly 5 achieves linear distance adjustment of the grinding head 6 via a lead screw 53. The sliding connection between the fixed seat 51 and the movable seat 52 provides guidance for telescopic movement. When the rotating motor 511 drives the lead screw 53 to rotate, the ball bearing slider 54, which meshes with the lead screw 53, causes the movable seat 52 to slide along the fixed seat 51, thereby adjusting the extension length of the grinding head 6. The precise cooperation between the lead screw 53 and the ball bearing slider 54 ensures accurate control of the telescopic distance, meeting the distance adaptation requirements of different workstations.

[0040] The grinding head 6 is powered by a drive motor 61, which is connected to the grinding head 6 via a mounting base 62. The drive motor 61 directly drives the grinding head 6 to rotate at high speed to achieve surface grinding. The mounting base 62 facilitates the disassembly and maintenance of the grinding head 6, ensuring stable and efficient power transmission.

[0041] Detailed operating procedures

[0042] In use, pull out the movable positioning pin 24 on the mobile trolley 1 and push the trolley along the ground rail 2 (manually or with auxiliary power). Observe the alignment of the trolley position with the movable positioning hole 23 on the ground rail 2. When the trolley reaches the target workstation, insert the movable positioning pin 24 into the corresponding movable positioning hole 23 to ensure that the pin is fully engaged, thus fixing the trolley position.

[0043] Pull out the steering positioning pin 41 on the rotary seat 4, and rotate the rotary seat 4 to move the grinding head 6 to the target direction (such as switching to the angle corresponding to another production line). When the steering positioning pin 41 on the rotary seat 4 is aligned with the steering positioning hole 31 on the moving seat 3, insert the pin to complete the angle fixation, ensuring that the direction of the grinding head 6 is perpendicular to the surface of the workpiece to be ground or meets the process requirements.

[0044] Start the rotating motor 511, which drives the lead screw 53 to rotate. The ball slider 54, which meshes with the lead screw 53, causes the movable seat 52 to slide along the fixed seat 51. When the grinding head 6 reaches the appropriate working position, turn off the rotating motor 511. The telescopic component 5 maintains its current length due to the self-locking characteristics of the lead screw 53 and the ball slider 54.

[0045] Start the drive motor 61 on the mounting base 62, and the motor drives the grinding head 6 to rotate at high speed to perform grinding operations.

[0046] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not a limitation on the scope of protection of the present utility model. Based on the technical solution of the present utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the present utility model.
