In actual production, due to the complex shape and hard material (usually high manganese steel, cast iron, or composite materials) of grinding bowl liners, existing grinding equipment often adopts a unidirectional movement structure, which is difficult to adapt to the grinding requirements of workpieces of different specifications. Especially when processing grinding bowl liners with curved or beveled edges, conventional equipment often cannot achieve good contact between the grinding head and the workpiece surface, resulting in uneven grinding, low efficiency, and even damage to the workpiece. Summary of the Invention

Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2(The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0015] Please see Figure 1-4 This application provides a technical solution: a side trimming device for a grinding bowl liner, including a worktable 9, a workpiece mounting frame 8 on the worktable 9, a transverse drive group 7 for controlling the transverse movement of the grinding group on one side of the workpiece mounting frame 8, a lateral mounting plate 16 connected to the movable end of the transverse drive group 7, and the workpiece mounting frame 8 providing a mounting position for the transverse drive group 7.

[0016] Specifically, the workpiece mounting bracket 8 includes a support pad 6 and a vertical support plate 13, with the support pad 6 located on the lower surface of the vertical support plate 13.

[0017] Furthermore, the support plate 6 is provided with a protrusion, which corresponds to the rectangular hole provided at the lower end of the vertical support plate 13.

[0018] The support plate 6 is located at the bottom and serves as a preliminary positioning tool; the support plate 6 has a protrusion that cooperates with the rectangular hole at the bottom of the vertical support plate 13 to achieve quick alignment and installation.

[0019] The vertical support plate 13 has a concave structure with a strip groove in its middle plate-like structure. Fasteners pass through the strip groove and connect to the threaded holes of the fixing plate in the transverse drive group 7, which facilitates the adjustment and installation of the transverse drive group 7.

[0020] The transverse drive assembly 7 ensures high-precision movement, driving the lateral mounting plate 16 to move precisely along the horizontal direction (X-axis) to adapt to the grinding needs of different positions.

[0021] The lateral mounting plate 16 is provided with a guide groove 11, and a connecting shaft 12 is slidably connected to the guide groove 11. The connecting shaft 12 is connected to an intermediate connecting member 10 and a telescopic driving member 14. The lateral mounting plate 16 is also provided with a hinge seat 5. A side frame support plate 17 is provided on one side of the hinge seat 5. The intermediate connecting member 10 is rotatably connected to a connecting support 15 provided on one side of the side frame support plate 17.

[0022] The guide groove 11 provides a sliding path for the connecting shaft 12, thereby guiding the movement direction of the intermediate connecting member 10.

[0023] The intermediate connector 10 serves as a transmission medium, transmitting the power of the telescopic drive 14 to the side frame support plate 17 and simultaneously achieving angle adjustment. One end is connected to the connecting shaft 12, and the other end forms a rotatable connection with the connecting support 15. By pushing or pulling the intermediate connector 10 through telescopic movement, the side frame support plate 17 is driven to swing, thereby achieving grinding angle adjustment. The hinge seat 5 serves as a rotation fulcrum, allowing the side frame support plate 17 to swing around it.

[0024] A vertical moving seat 4 is provided on the other side of the side frame support plate 17, and a grinding assembly is provided on the sliding end of the vertical moving seat 4.

[0025] The side support plate 17 is installed on one side of the hinge seat 5; it is connected to the intermediate connecting piece 10 and the vertical moving seat 4 to realize angle rotation. The vertical moving seat 4 controls the up and down movement of the grinding group on the vertical Z-axis to adapt to the grinding needs at different height positions. The vertical moving seat 4 is installed on one side of the side support plate 17; its sliding end is connected to the grinding group, which drives it to move up and down. The grinding group performs actual grinding operations on the side of the grinding bowl liner.

[0026] The upper surface of the workbench 9 is also provided with a longitudinal adjustment seat 1, and a material placement rack 2 for placing liner plates is slidably arranged on the longitudinal adjustment seat 1.

[0027] The longitudinal adjustment seat 1 allows the material placement rack 2 to slide along the Y-axis in the front-to-back direction to accommodate grinding bowl liners of different lengths. The material placement rack 2 is used to support the grinding bowl liners to be ground and to ensure their stability and accuracy during the grinding process.

[0028] The horizontal drive group 7, the longitudinal adjustment seat 1, and the vertical moving seat 4 are all composed of servo motors, lead screw transmission mechanisms, and slide rails, forming a precise moving adjustment group.

[0029] Furthermore, the grinding assembly includes a grinding mounting plate 3, a grinding motor, and a grinding head. The grinding mounting plate 3 is connected to the sliding end of the vertical moving seat 4. The grinding mounting plate 3 is equipped with a grinding motor, and the driving end of the grinding motor is equipped with a grinding head.

[0030] The grinding mounting plate 3 is a support platform for the grinding assembly, used to fix the grinding motor and grinding head, and is connected to the vertical moving base 4.

[0031] Grinding heads are mostly made of diamond grinding wheels, resin grinding wheels, or ceramic grinding wheels; the type can be flexibly changed according to the material of the grinding bowl liner.

[0032] Furthermore, the longitudinal adjustment seat 1 is a guide rail structure with a scale, and the material placement rack 2 can slide and lock on the guide rail.

[0033] Furthermore, an electromagnetic structure is provided at the upper end of the material placement rack 2, and the electromagnetic structure is located below the workpiece placement plate in the material placement rack 2.

[0034] The material placement rack 2 is used to support the grinding bowl liner to be ground and to ensure its stability and centering during the grinding process.

[0035] The electromagnetic structure is embedded under the workpiece placement plate. It is usually an electromagnetic chuck or electromagnetic coil assembly. It uses electromagnetic principles to generate an adsorption force to firmly adsorb the metal grinding bowl liner onto the placement plate, preventing the workpiece from shifting due to vibration or cutting force during the grinding process.

[0036] In use: Place the grinding bowl liner to be ground stably on the material placement rack 2, activate the electromagnetic structure to ensure the workpiece is firmly attracted; activate the longitudinal adjustment seat 1, slide the material placement rack 2 along the guide rail to the appropriate position according to the workpiece size, activate the transverse drive group 7 according to the workpiece placement position, adjust the grinding group to the working area, activate the vertical moving seat 4 to lower the grinding group to near the workpiece surface, activate the telescopic drive component 14 to push the intermediate connecting component 10, drive the side frame support plate 17 to swing around the hinge seat 5, realize the grinding angle adjustment, so that the grinding head is in contact with the side of the workpiece, and the grinding motor starts to grind the side. During the grinding process, the telescopic drive component 14 is constantly adjusted according to the side angle to ensure that the grinding head can always be in contact with the side of the workpiece, thus improving grinding efficiency.

[0037] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
