Description

Technical Field

[0001] This utility model relates to the field of ceramic machinery technology, and in particular to an automatic feeding grinding head device for a ceramic grinding machine. Background Technology

[0002] As disclosed in patent application CN201810659549.X, most domestic wet edge grinding machines currently use grinding heads that drive the lower grinding head body axially via an upper worm gear assembly. The lines of action of the adjusting rod's extension and retraction are parallel to those of the main shaft's extension and retraction. However, in actual operation, due to machining and assembly errors, these two lines of action are often not parallel. The vertical component of the force can cause the main shaft or push rod to bend and deform, resulting in inflexible extension and retraction. The threaded feed grinding head designed in this project avoids the problem of poor main shaft extension and retraction caused by the non-parallel force directions of the main shaft and the worm gear adjusting rod in traditional structures, making the main shaft's extension and retraction more flexible. Summary of the Invention

[0003] The purpose of this utility model is to provide an automatic feeding edge grinding head device for ceramic edge grinding machines that is flexible in extension and retraction and allows for smooth axial feeding of the grinding head body.

[0004] The automatic feeding grinding head device for a ceramic grinding machine of this utility model is implemented as follows: it includes a base, a grinding head mechanism mounted on the base, and a feeding mechanism mounted between the base and the grinding head mechanism. The grinding head mechanism includes a sleeve, a motor fixed to one end of the sleeve, a grinding head shaft rotatably inserted into the sleeve, and a grinding head component. One end of the grinding head shaft is connected to the power output shaft of the motor via a coupling, and the other end of the grinding head shaft extends out of the sleeve and connects to the grinding head component. The feeding mechanism includes a sliding sleeve mounted on the base and a threaded sleeve mounted on the sleeve. The sleeve slides through the threaded sleeve and the sliding sleeve in sequence. The threaded sleeve is threaded onto the sliding sleeve and is connected to the sleeve, driving the sleeve to move back and forth relative to the sliding sleeve. An electric adjustment structure is provided, including a motor frame connected to the sleeve, an active synchronous pulley mounted on the motor frame driven by a servo motor via a planetary reducer, a passive synchronous pulley mounted on the threaded sleeve, and a synchronous belt. The active synchronous pulley drives the passive synchronous pulley to rotate via the synchronous belt, thereby driving the threaded sleeve to rotate.

[0005] In use, the motor drives the grinding head component to rotate via the grinding head shaft. The grinding wheel on the grinding head component grinds the workpiece. When adjusting the positional relationship between the grinding head component and the workpiece, the threaded sleeve is rotated by the electric adjustment structure to adjust the positional relationship between the threaded sleeve and the sliding sleeve. The threaded sleeve then drives the sleeve to move back and forth, thereby adjusting the positional relationship between the grinding head mechanism and the sliding sleeve, and in turn, adjusting the positional relationship between the grinding head component and the workpiece to ensure that the grinding wheel of the grinding head component can process the workpiece.

[0006] The system employs a threaded sleeve and a sliding sleeve. 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, causing 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 processing and assembly errors, ensuring flexible extension and retraction and smooth axial feed of the grinding head body.

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

[0008] Compared with existing technologies, this invention has the advantages of flexible extension and retraction and smooth axial feeding of the grinding head body. Attached Figure Description

Detailed Implementation

[0012] The automatic feeding grinding head device for ceramic grinding machines according to this utility model will now be described in further detail with reference to the accompanying drawings and embodiments:

[0013] Example 1: As shown in 1 and 2, the feeding and grinding head device for a ceramic grinding machine of this utility model is implemented as follows: it includes a base 1, a grinding head mechanism 2 disposed on the base 1, and a feeding mechanism 3 disposed between the base 1 and the grinding head mechanism 2. The grinding head mechanism 2 is characterized by comprising 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 inside the sleeve 201, a grinding head component 205, and a coupling 206. One end of the grinding head shaft 204 is connected to the power output shaft of the motor 202 via the coupling 206, and the other end of the grinding head shaft 204 extends out of the sleeve 201 and is connected to the grinding head component 205. The feeding mechanism 3 includes a sliding sleeve 301 disposed on the base 1 and a threaded sleeve 302 disposed on the sleeve 201. The base 1 and the sliding sleeve 301 are machined together as a whole. The sleeve 201 slides through the threaded sleeve 302 and the sliding sleeve 301 in sequence. The threaded sleeve 302 is screwed onto the sliding 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 sliding sleeve 301. An electric adjustment structure 5 is provided. The electric adjustment structure 5 includes a motor frame 501 connected to the sleeve 201, an active synchronous pulley 504 driven by a servo motor 502 through a planetary reducer 503 and mounted on the motor frame 501, a passive synchronous pulley 505 mounted on the threaded sleeve 302 (the retaining ring 3022 of the threaded sleeve 302), and a synchronous belt 506. 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.

[0014] The threaded sleeve 302 includes a threaded sleeve body 3021 threadedly connected to the sliding sleeve 301 and a retaining ring 3022. The retaining ring 3022 is fixed to the end of the threaded sleeve body 3021, and a circular groove 3023 is left between the retaining ring 3022 and the end of the threaded sleeve body 3021. A circular baffle 3024 embedded in the circular groove 3023 is connected to the sleeve 201 corresponding to the circular groove 3023. The threaded sleeve 302, which moves back and forth relative to the sliding sleeve 301, drives the circular baffle 3024 to move back and forth through the circular groove 3023, thereby driving the sleeve 201 to move back and forth.

[0015] Preferably, a sleeve positioning mechanism 4 is provided on the sliding sleeve 301. The sleeve positioning mechanism 4 includes a cylinder 404 fixed on the sliding sleeve 301 and a positioning pressure head 405 driven by the piston rod of the cylinder 404. The piston rod of the cylinder 404 passes through the sliding sleeve 301, so that the positioning pressure head 405 reaches the outer surface of the sleeve 201. During operation, the positioning pressure head 405 driven by the piston rod of the cylinder 404 presses tightly against the outer surface of the sleeve 201, so that the positional relationship between the sleeve 201 and the sliding sleeve 301 remains fixed.

[0016] Preferably, a front sealing gasket 6 is provided between the front end of the sliding sleeve 301 and the sleeve 201, and a rear sealing gasket 7 is provided between the rear end of the threaded sleeve 302 and the sleeve 201. The front sealing gasket 6 and the rear sealing gasket 7 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.

[0017] In use, the motor 202 drives the grinding head component 205 to rotate via the grinding head shaft 204. The grinding wheel on the grinding head component 205 grinds the workpiece. When adjusting the positional relationship between the grinding head component 205 and the workpiece, the electric adjustment structure 5 drives the threaded sleeve 302 to rotate, thereby adjusting the positional relationship between the threaded sleeve 302 and the sliding sleeve 301. The threaded sleeve 302 then 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 thus adjusting the positional relationship between the grinding head component 205 of the grinding head mechanism 2 and the workpiece, so as to ensure that the grinding wheel of the grinding head component 205 can process the workpiece. After the adjustment is completed, the positioning pressure head 405 driven by the piston rod of the cylinder 404 presses tightly against the outer surface of the sleeve 201, so that the positional relationship between the sleeve 201 and the sliding sleeve 301 remains fixed.
