Description

Technical Field

[0001] This utility model relates to the field of ceramic machinery technology, and in particular to a feeding edge grinding head device for a ceramic edge 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 a feed grinding head device for a ceramic grinding machine that is flexible in extension and retraction and allows for smooth axial feeding of the grinding head body.

[0004] The feeding and grinding head device for a ceramic grinding machine of this utility model is implemented as follows: it includes a base, a grinding head mechanism set on the base, and a feeding mechanism set between the base and the grinding head mechanism. The grinding head mechanism includes a sleeve, a motor fixed at one end of the sleeve, a grinding head shaft rotatably connected inside 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 extends out of the sleeve and is connected to the grinding head component. The feeding mechanism includes a sliding sleeve set on the base and a threaded sleeve set 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 operating handle is set on the main body of the threaded sleeve, and the operating handle drives 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. To adjust the positional relationship between the grinding head component and the workpiece, the threaded sleeve is rotated by operating the handle 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 feed grinding head device for a ceramic grinding machine according to the present invention 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 including 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 bearing 203 via the coupling 206. The power output shaft of the motor 202 is connected, 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 sliding sleeve 301 set on the base 1 and a threaded sleeve 302 set on the sleeve 201. The base 1 and the sliding sleeve 301 are integrally machined together. The sleeve 201 slides through the threaded sleeve 302 and the sliding sleeve 301 in sequence. The threaded sleeve 302 is threaded 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.

[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. An operating handle 303 (four of them are evenly distributed along the circumference of the threaded sleeve body 3021) is provided on the threaded sleeve body 3021, and the threaded sleeve 302 is rotated by the operating handle 303.

[0015] 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 reaches the sleeve 201. The screw 402 is screwed onto the threaded hole 403.

[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. To adjust the positional relationship between the grinding head component 205 and the workpiece, the operating handle 303 is turned to rotate the threaded sleeve 302, 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 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 handle 401 drives the screw 402 to rotate, so that the screw 402 is close to the sleeve 201, and the positional relationship between the sleeve 201 and the sliding sleeve 301 remains unchanged.
