[0023] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Reference Figure 1 , 2As shown in Figure 3, the grinding head slide adjustment structure according to this embodiment of the utility model includes a fixed base 100, a movable base 200, and an adjustment mechanism 300; the movable base 200 is movably mounted on the fixed base 100, and the movable base 200 is provided with a connecting base 210; the adjustment mechanism 300 includes a lead screw 310, a bearing seat 320, two tapered roller bearings 330 with adjustable axial clearance, and an adjustment sleeve 340; the lead screw 310 is rotatably mounted in the bearing seat 320 and connected to the connecting base 210. The screw connection is used. The bearing housing 320 is mounted on the fixed base 100. Two tapered roller bearings 330 are arranged back to back and between the screw 310 and the bearing housing 320. The side wall of the screw 310 has a protrusion 311. The right side of the protrusion 311 abuts against the leftmost tapered roller bearing 330. The adjusting sleeve 340 is installed in the bearing housing 320 and sleeved on the outside of the screw 310, and can move left and right. The left end of the adjusting sleeve 340 abuts against the right side of the rightmost tapered roller bearing 330.

[0026] The lead screw 310 is mounted in the bearing housing 320 via tapered roller bearings 330, allowing the lead screw 310 to rotate. This rotation of the lead screw 310 drives the moving seat 200 to move left and right. Furthermore, by providing an adjustable sleeve 340 that can move left and right, the axial clearance of the two tapered roller bearings 330 can be adjusted, thereby adjusting the axial position of the lead screw 310. This allows for fine-tuning of the lead screw 310's position, improving the accuracy of the grinding head.

[0027] It is understandable that there is a small gap between the two tapered roller bearings 330 arranged back to back. The axial clearance of the two tapered roller bearings 330 can be adjusted by the adjustable sleeve 340 that can move left and right. This allows the lead screw 310 to be adjusted by a small distance. The lead screw 310 can then drive the grinding head to adjust by a small distance through the connecting seat 210 and the moving seat 200, thereby adjusting the grinding head's accuracy.

[0028] During operation, the grinding head is mounted on the movable seat 200 and drives the lead screw 310 to rotate. The lead screw 310 drives the movable seat 200 to move left and right on the fixed seat 100 through the connecting seat 210 that is threaded to it, so that the grinding head can perform edge grinding on glass or objects that need edge grinding.

[0029] During operation, the grinding head is subjected to axial force, which is transmitted to the lead screw 310 through the moving seat 200 and the connecting seat 210. The lead screw 310 then transmits the force to the tapered roller bearing 330, which in turn bears the axial force of the grinding head. When it is necessary to adjust the axial load capacity of the tapered roller bearing 330 or to adjust the position of the lead screw 310, the adjusting sleeve 340 moves to the left or right to adjust the axial clearance of the tapered roller bearing 330.

[0030] In some embodiments of this utility model, such as Figure 3 As shown, the tapered roller bearing 330 includes an inner ring 331 and an outer ring 332. The right side of the protrusion 311 abuts against the inner ring 331 of the leftmost tapered roller bearing 330. The adjusting sleeve 340 is threadedly connected to the lead screw 310. The adjusting sleeve 340 can abut against the inner ring 331 of the rightmost tapered roller bearing 330. By providing the protrusion 311 and screwing the adjusting sleeve 340 to the lead screw 310, the axial clearance adjustment of the two tapered roller bearings 330 is realized, making the structure of the adjusting mechanism 300 simple.

[0031] like Figure 3 As shown, when it is necessary to adjust the axial clearance of the tapered roller bearing 330, the adjusting sleeve 340 is rotated to move it to the left, and the adjusting sleeve 340 abuts against the inner ring 331 of the rightmost tapered roller bearing 330, pressing the inner rings 331 of the two tapered roller bearings 330 between the protrusion 311 and the adjusting sleeve 340, thereby adjusting the axial clearance of the tapered roller bearing 330. Alternatively, the adjusting sleeve 340 can be rotated to move it to the right, loosening the inner rings 331 of the two tapered roller bearings 330, thereby adjusting the axial clearance of the tapered roller bearing 330.

[0032] Specifically, the adjusting sleeve 340 has an internal thread, and the internal thread of the adjusting sleeve 340 is threadedly connected to the external thread of the lead screw 310.

[0033] In a further embodiment of this utility model, such as Figure 3 As shown, the right side of the adjusting sleeve 340 extends out of the bearing housing 320, making it convenient for the user to rotate the adjusting sleeve 340.

[0034] In a further embodiment of this utility model, the lead screw 310 is threadedly connected to a nut 400 for adjusting the left and right positions of the adjusting sleeve 340. The nut 400 is located to the right of the adjusting sleeve 340. When it is necessary to adjust the axial clearance of the tapered roller bearing 330, the nut 400 is rotated so that the adjusting sleeve 340 can move left and right to adjust its position.

[0035] Specifically, the internal thread of nut 400 is threadedly connected to the external thread of lead screw 310.

[0036] Specifically, the adjusting sleeve 340 is equivalent to a force transmission component located between the tapered roller bearing 330 and the nut 400. The adjusting sleeve 340 is simply sleeved around the lead screw 310 and can move left and right, and is not a screw connection.

[0037] In a further embodiment of this utility model, such as Figure 3As shown, the adjustment mechanism 300 also includes a bearing sleeve 350, an elastic element 360, and an adjustment element 370 for adjusting the compression degree of the elastic element 360. The bearing housing 320 has a mounting cavity 321. The lead screw 310, adjustment sleeve 340, bearing sleeve 350, and elastic element 360 are all located in the mounting cavity 321. The inner wall of the mounting cavity 321 includes an extension wall 3211 extending in the radial direction of the bearing housing 320. The tapered roller bearing 330 is disposed between the bearing sleeve 350 and the lead screw 310. At least a portion of the adjustment element 370 is movably disposed in the mounting cavity 321. The adjustment element 370 is located to the right of the extension wall 3211. The bearing sleeve 350 and the elastic element 360 are located between the extension wall 3211 and the adjustment element 370. The elastic element 360 is located to the right of the bearing sleeve 350.

[0038] By providing a bearing sleeve 350, an elastic element 360, and an adjusting element 370, there is no force-bearing structure between the lead screw 310 and the fixed seat 100. The tapered roller bearing 330 can transmit a portion of the force to the elastic element 360 through the bearing sleeve 350, thereby improving the force-bearing capacity of the adjusting mechanism 300. The adjusting element 370 can adjust the compression degree of the elastic element 360, thereby adjusting the load-bearing capacity of the elastic element 360.

[0039] The bearing sleeve 350 remains in contact with the extension wall 3211 under the action of the elastic element 360; when it is necessary to adjust the compression degree of the elastic element 360, the driving adjustment element 370 is moved to the left or right. When moving to the left, the adjustment element 370 compresses the elastic element 360, and the elastic element 360 shortens its length. When moving to the right, the elastic element 360 restores its length.

[0040] Specifically, the elastic element 360 is sleeved outside the adjusting sleeve 340.

[0041] Specifically, a shim 390 is provided inside the bearing housing 350, and the shim 390 is located between the two tapered roller bearings 330 to separate the two tapered roller bearings 330.

[0042] Specifically, the right side inside the bearing sleeve 350 has a blocking portion 351 extending in the radial direction. The blocking portion 351 is used to prevent the tapered roller bearing 330 from disengaging from the bearing sleeve 350 to the right. A part of the adjusting sleeve 340 is located inside the blocking portion 351. By providing the blocking portion 351, the two tapered roller bearings 330 are confined between the protrusion 311 and the blocking portion 351, and the two tapered roller bearings 330 are facilitated to be installed inside the bearing sleeve 350.

[0043] Specifically, the left end of the elastic member 360 abuts against the right side of the blocking part 351.

[0044] In a further embodiment of this utility model, such as Figure 3As shown, at least a portion of the adjusting member 370 is disposed within the bearing housing 320 and threadedly connected to the bearing housing 320, thus simplifying the structure of the adjusting mechanism 300. During operation, rotating the adjusting member 370 causes it to move to the left or right, thereby adjusting the degree of compression of the elastic member 360.

[0045] Specifically, at least a portion of the outer circumferential surface of the adjusting member 370 has an external thread, and the bearing seat 320 has an internal thread corresponding to the position of the adjusting member 370. The external thread of the adjusting member 370 is threadedly connected to the internal thread of the bearing seat 320, and the compression degree of the elastic member 360 is adjusted by rotating the adjusting member 370.

[0046] In a further embodiment of this utility model, such as Figure 3 As shown, the adjusting sleeve 340 passes through the adjusting member 370, so that the adjusting member 370 can be moved left and right and fitted outside the adjusting sleeve 340, which can reduce the length of the bearing seat 320 in the left and right direction.

[0047] In a further embodiment of this utility model, such as Figure 3 As shown, a portion of the adjusting element 370 is located outside the bearing housing 320, making it convenient for the user to adjust the adjusting element 370.

[0048] In a further embodiment of this utility model, the elastic element 360 is a spring.

[0049] In some embodiments of this utility model, such as Figure 1 As shown, the adjustment mechanism 300 also includes a connecting sleeve 380. The bearing seat 320 is mounted on the fixed seat 100 through the connecting sleeve 380. The lead screw 310 is located inside the connecting sleeve 380. The connecting sleeve 380 is provided to extend the travel of the moving seat 200.
