Description

Technical Field

[0001] The invention relates to the technical field of ceramic machinery, in particular to a feeding and edge grinding head device for a ceramic edge grinding machine. Background Art

[0002] As disclosed in patent application CN201810659549.X, the grinding heads currently used in domestic wet edge grinding machines mostly use the upper worm gear assembly to push the lower grinding head body for axial feeding. The line of action of the adjustment rod extension and the line of action of the main shaft extension are two parallel lines. However, in actual operation, due to the influence of processing and assembly errors, the two lines of action are usually not parallel. The vertical force component can cause the main shaft or push rod to bend and deform, resulting in inflexible extension. The threaded feed edge grinding head designed in this project avoids the problem of poor spindle extension caused by the non-parallel direction of the action force between the main shaft and the worm gear adjustment rod in the traditional structure, making the extension of the main shaft more flexible. Summary of the Invention

[0003] The object of the present invention is to provide a feeding edge grinding head device for a ceramic edge grinding machine, which has flexible extension and contraction and smooth axial feeding of the grinding head body.

[0004] The feeding grinding head device for a ceramic edge grinding machine of the present invention is realized as follows: it includes a base, a grinding head mechanism arranged on the base, and a feeding mechanism arranged between the base and the grinding head mechanism. The special feature of the feeding grinding head device is that the grinding head mechanism includes a sleeve, a motor fixed at one end of the sleeve, a grinding head shaft rotatably connected to the sleeve, and a grinding head component. One end of the grinding head shaft is connected to the power output shaft of the motor through a coupling, and the other end of the grinding head shaft passes through the outside of the sleeve and is connected to the grinding head component. The feeding mechanism includes a sliding sleeve arranged on the base and a threaded sleeve arranged on the sleeve. The sleeve slides through the threaded sleeve and the sliding sleeve in turn. The threaded sleeve is screwed on the sliding sleeve. The threaded sleeve is connected to the sleeve and drives the sleeve to move back and forth relative to the sliding sleeve.

[0005] During use, the motor drives the grinding head component to rotate through the grinding head shaft, and the workpiece is ground by the grinding wheel on the grinding head component. When adjusting the positional relationship between the grinding head component and the workpiece, the threaded sleeve is rotated to adjust the positional relationship between the threaded sleeve and the sliding sleeve. The threaded sleeve drives the sleeve to move back and forth, thereby adjusting the positional relationship between the grinding head mechanism and the sliding sleeve, and then adjusting the positional relationship between the grinding head component of the grinding head mechanism and the workpiece to ensure that the grinding wheel of the grinding head component can process the workpiece.

[0006] A threaded sleeve and a sliding sleeve are used, and the sleeve slides through the threaded sleeve and the sliding sleeve in sequence. The threaded sleeve is screwed onto the sliding sleeve, and the threaded sleeve is rotatably connected to the sleeve and drives the sleeve to move back and forth relative to the sliding sleeve. During adjustment, the rotation axis of the threaded sleeve coincides with the axis of the sleeve. During processing and assembly, it will not be affected by the processing and assembly errors, ensuring flexible telescopic movement and smooth axial feed of the grinding head body.

[0007] Preferably, a sleeve positioning mechanism is provided on the sliding sleeve, and the sleeve positioning mechanism fixes the positional relationship between the sleeve and the sliding sleeve to prevent the positional relationship between the sleeve and the sliding sleeve from changing during the grinding process of the workpiece.

[0008] Compared with the prior art, the present invention has the advantages of flexible telescopicity and smooth axial feeding of the grinding head body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0011] The feed edge grinding head device for a ceramic edge grinding machine of the present invention will now be described in further detail with reference to the accompanying drawings and embodiments: Example 1: As shown in: 1 and 2, the feed grinding head device for a ceramic edge grinding machine of the present invention is implemented as follows, including a base 1, a grinding head mechanism 2 arranged on the base 1, and a feeding mechanism 3 arranged between the base 1 and the grinding head mechanism 2. The special feature of the grinding head mechanism 2 is that it includes a sleeve 201, a motor 202 fixed to one end of the sleeve 201, a grinding head shaft 204 rotatably connected to a bearing 203 in the sleeve 201, a grinding head component 205, and a coupling 206. One end of the grinding head shaft 204 is connected to the motor through the coupling 206. The grinding head shaft 204 is connected to the power output shaft of the machine 202, and the other end of the grinding head shaft 204 passes through the sleeve 201 and is connected to the grinding head component 205. The feeding mechanism 3 includes a sleeve 301 arranged on the base 1 and a threaded sleeve 302 arranged on the sleeve 201. The base 1 and the sleeve 301 are processed as a whole. The sleeve 201 slides through the threaded sleeve 302 and the sleeve 301 in turn. The threaded sleeve 302 is screwed on the sleeve 301. The threaded sleeve 302 is rotatably connected to the sleeve 201 and drives the sleeve 201 to move back and forth relative to the sleeve 301.

[0012] The threaded sleeve 302 includes a threaded sleeve main body 3021 and a retaining ring 3022 which is screwed onto the sliding sleeve 301. The retaining ring 3022 is fixed to the end of the threaded sleeve main body 3021, and an annular groove 3023 is left between the retaining ring 3022 and the end of the threaded sleeve main body 3021. An annular retaining piece 3024 embedded in the annular groove 3023 is connected to the sleeve 201 corresponding to the annular groove 3023. The threaded sleeve 302 which moves back and forth relative to the sliding sleeve 301 drives the annular retaining piece 3024 to move back and forth through the annular groove 3023, thereby driving the sleeve 201 to move back and forth. An operating handle 303 (four of which are evenly distributed along the circumference of the threaded sleeve main body 3021) is provided on the threaded sleeve main body 3021, and the threaded sleeve 302 is driven to rotate by the operating handle 303.

[0013] Preferably, a sleeve positioning mechanism 4 is provided on the sliding sleeve 301 . The sleeve positioning mechanism 4 includes a screw 402 with a handle 401 , and a threaded hole 403 that passes through the sliding sleeve 301 and directly reaches the sleeve 201 .

The front sealing gasket 6 and the rear sealing gasket 7 are provided to prevent external contaminants from entering between the sliding sleeve 301, the threaded sleeve 302 and the sleeve 201, thereby preventing the sliding sleeve 301, the threaded sleeve 302 and the sleeve 201 from moving smoothly.

[0015] During use, the motor 202 drives the grinding head component 205 to rotate through the grinding head shaft 204, and grinds the workpiece through the grinding wheel on the grinding head component 205. When adjusting the positional relationship between the grinding head component 205 and the workpiece, the operating handle 303 is pulled to rotate the threaded sleeve 302 to adjust the positional relationship between the threaded sleeve 302 and the sliding sleeve 301. The threaded sleeve 302 drives the sleeve 201 to move back and forth, thereby adjusting the positional relationship between the grinding head mechanism 2 and the sliding sleeve 301, and thereby adjusting the positional relationship between the grinding head component 205 of the grinding head mechanism 2 and the workpiece to ensure that the grinding wheel of the grinding head component 205 can process the workpiece. After the adjustment is completed, the screw 402 is driven to rotate by the handle 401, so that the screw 402 is close to the sleeve 201, so that the positional relationship between the sleeve 201 and the sliding sleeve 301 remains fixed.

[0016] Example 2: As shown in 3 and 4, this example is based on Example 1 and is provided with an electric adjustment structure 5. The electric adjustment structure 5 includes a motor frame 501 connected to the sleeve 201, an active synchronous pulley 504 arranged on the motor frame 501 and driven by a servo motor 502 through a planetary reducer 503, a passive synchronous pulley 505 and a synchronous belt 506 arranged on the threaded sleeve 302 (the retaining ring 3022 of the threaded sleeve 302). The active synchronous pulley 504 drives the passive synchronous pulley 505 to rotate through the synchronous belt 506, thereby driving the threaded sleeve 302 to rotate.

[0017] The sleeve positioning mechanism 4 includes a cylinder 404 fixed to the sleeve 301 and a positioning ram 405 driven by the piston rod of the cylinder 404. The piston rod of the cylinder 404 extends through the sleeve 301, allowing the positioning ram 405 to directly contact the outer surface of the sleeve 201. During operation, the positioning ram 405 driven by the piston rod of the cylinder 404 presses tightly against the outer surface of the sleeve 201, maintaining a fixed position between the sleeve 201 and the sleeve 301.
