[0029] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention.

[0030] Second, the "one embodiment" or "embodiment" referred to herein means a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate or selectively exclusive of other embodiments.

[0031] Embodiment 1

[0032] Referring to Figures 1 to 6 , which is the first embodiment of the present invention. This embodiment provides a stator inner wall grinding device that can achieve the effect of cleaning dust or grinding chips during grinding. It includes a support component 100, which includes a support table 101, a mounting opening 102 provided on the support table 101, a sliding seat 103 provided in the mounting opening 102, and a workpiece to be processed 104 provided on the upper side of the sliding seat 103; a grinding component 200, which includes a rotating assembly 201 provided in the support table 101, a dust suction assembly 202 provided on the rotating assembly 201, a power assembly 203 provided at the bottom of the rotating assembly 201, and a switching assembly 204 provided on the power assembly 203; a feeding component 300, which includes a moving assembly 301 provided on the support table 101, an adjusting assembly 302 provided on the moving assembly 301, a connecting assembly 303 provided on the adjusting assembly 302, a pressing assembly 304 provided on the connecting assembly 303, and a linkage assembly 305 provided on the pressing assembly 304.

[0033] Specifically, the support table 101 here is composed of a box body, a support table 101 surface, and multiple internal support plates. The setting of the mounting opening 102 prevents the sliding seat 103 from getting stuck. An expansion slot is provided in the mounting opening 102, and an expansion piece is fixedly connected to the sliding seat 103 to allow the expansion piece to slide in the expansion slot to fill the gap between the mounting opening 102 and the sliding seat 103. The workpiece to be processed 104 here refers to the stator.

[0034] Further, the rotating assembly 201 includes a fixed seat 201a fixed on the support table 101. The fixed seat 201a and the sliding seat 103 are hollow inside. Long strip cylinders 201b are fixedly connected to both the fixed seat 201a and the sliding seat 103. A bearing 201c is provided inside the long strip cylinder 201b. A main shaft 201d passes through and is fixedly connected inside the bearing 201c. A grinding head 201e extending to the lower side of the workpiece 104 to be processed is fixedly connected to the upper end of the main shaft 201d. A first gear 201f is fixedly connected to the upper long strip cylinder 201b. An extension plate is fixedly connected to the support table 101, and a first motor 201h is fixedly connected to the extension plate. A second gear 201i meshing with the first gear 201f is fixedly connected to the output shaft of the first motor 201h; the dust suction assembly 202 includes a connection seat 202a fixedly connected to the fixed seat 201a. A dust suction pipe 202b extending to the outer end is fixedly connected to the connection seat 202a. A sealing cover 202c is fixedly connected to the connection seat 202a. A bearing sleeve 202d is fixedly connected to the main shaft 201d. A connection bar 202e is provided between the sealing cover 202c and the bearing sleeve 202d. A sliding cylinder 202f is slidably connected inside the upper long strip cylinder 201b. An inner groove 202h is provided on the wall of the sliding cylinder 202f. The bearing sleeve 202d is elastically connected to the inner wall of the inner groove 202h through a telescopic spring 202i; the power assembly 203 includes a second motor 203a fixedly connected to the support table 101. Belt pulleys 203b are fixedly connected to the output shaft of the second motor 203a and the lower end of the main shaft 201d respectively. The two belt pulleys 203b are connected by a belt 203c.

[0035] It should be noted that the fixed seat 201a is fixed to the support table 101, and the fixed seat 201a is arranged below the sliding seat 103. Two long strip cylinders 201b are provided, and the center lines of the two long strip cylinders 201b are on the same straight line. The outer side wall of the bearing 201c is fixedly connected to the long strip cylinder 201b. The upper end of the sliding cylinder 202f extends to the upper side of the support table 101 here. The first gear 201f and the second gear 201i are deeply meshed here. When the sliding seat 103 moves left and right, the phenomenon that the first gear 201f and the second gear 201i are separated will not occur. When in use, the outer end of the dust suction pipe 202b is connected to a dust collector to absorb the grinding dust. The setting of the sealing cover 202c can prevent dust from entering the bearing 201c and affecting the rotation of the bearing 201c.

[0036] In use, first place the workpiece 104 to be processed on the base 202g and fix it. Then start the second motor 203a. The rotation of the second motor 203a drives the pulley 203b to rotate. The pulley 203b at the lower end of the main shaft 201d is driven to rotate through the belt 203c, so that the main shaft 201d rotates, driving the grinding head 201e to rotate for grinding. During grinding, press the sliding cylinder 202f so that the grinding head 201e enters the interior of the workpiece 104. When the sliding cylinder 202f moves, the telescopic spring 202i is compressed to facilitate the reset of the sliding cylinder 202f. Then the sliding seat 103 moves left and right, so that the grinding head 201e fits against the side wall of the workpiece 104 for grinding. The dust generated by grinding enters the long cylinder 201b from the sliding cylinder 202f and is finally discharged through the dust suction pipe 202b. When the main shaft 201d rotates, the output shaft of the first motor 201h rotates, driving the second gear 201i to rotate, causing the first gear 201f meshing with the second gear 201i to rotate, and causing the long cylinder 201b to rotate. Here, the rotation direction of the second motor 203a makes the rotation direction of the long cylinder 201b opposite to that of the main shaft 201d, so that the sliding cylinder 202f rotates in the opposite direction to the main shaft 201d, thereby increasing the relative rotation speed between the sliding cylinder 202f and the main shaft 201d, increasing the relative rotation speed between the main shaft 201d and the workpiece 104, and making the grinding faster.

[0037] In summary, by setting the grinding component 200, during grinding, the dust or grinding chips can be automatically absorbed by connecting a vacuum cleaner through the dust suction pipe 202b, avoiding the influence of dust or grinding chips on the machining of the turning tool and ensuring the overall machining accuracy.

[0038] Embodiment 2

[0039] Refer to Figures 1 to 6 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a switching component 204 for the inner wall grinding device of the stator, which solves the problem of how to conveniently replace the grinding head 201e. It includes a switching component 204, which includes a first ring 204a fixedly connected to the main shaft 201d. A plurality of limit holes 204b are provided on the first ring 204a. A first cylinder 204c is fixedly connected to the fixed seat 201a. The telescopic end of the first cylinder 204c is fixedly connected with an installation cylinder 204d. A plug rod 204e that cooperates with the limit hole 204b is slidably connected in the installation cylinder 204d. The plug rod 204e is elastically connected to the inner wall of the installation cylinder 204d through a first spring 204f. A through hole 204g that cooperates with the plug rod 204e is provided on the fixed seat 201a.

[0040] Specifically, the first spring 204f is arranged such that when the first cylinder 204c is pushed, even if the limiting hole 204b and the inserting rod 204e are not aligned, the first cylinder 204c can still be pushed. When the limiting hole 204b and the inserting rod 204e are not aligned, the main shaft 201d can be toggled at this time. Just toggle the main shaft 201d once to make the limiting hole 204b face the limiting rod, and then the main shaft 201d can be locked.

[0041] During use, the grinding head 201e wears significantly. When the grinding head 201e needs to be replaced, just start the first cylinder 204c. The first cylinder 204c extends, causing the mounting cylinder 204d to move towards the first ring 204a and the inserting rod 204e to move towards the limiting hole 204b. When the limiting hole 204b and the inserting rod 204e are not aligned, the inserting rod 204e abuts against the side wall of the first ring 204a, compressing the first spring 204f. Then, manually toggle the main shaft 201d. If it can be toggled, it indicates that the inserting rod 204e has not entered the limiting hole 204b. Then continue to toggle the main shaft 201d. When the limiting hole 204b on the first ring 204a is aligned with the inserting rod 204e, under the action of the first spring 204f, the inserting rod 204e enters the limiting hole 204b to limit the first ring 204a, thereby limiting the main shaft 201d. Thus, when disassembling the grinding head 201e, the main shaft 201d cannot rotate, facilitating the disassembly of the grinding head 201e.

[0042] In summary, by arranging the switching component 204, when replacing the grinding head 201e, the inserting rod 204e is inserted into the limiting hole 204b on the first ring 204a to prevent the main shaft 201d from rotating. Thus, when disassembling the grinding head 201e, the main shaft 201d will not rotate, facilitating the replacement of the grinding head 201e.

The L-shaped plate 302c and the push plate 302b are elastically connected by a second spring 302h; the connecting component 303 includes a first connecting plate 303a fixedly connected to the transmission plate 302d. The first connecting plate 303a is fixedly connected to the sliding seat 103. A second connecting plate 303b is fixedly connected to the transmission plate 302d.

[0045] Specifically, four second screw rods 302f are provided here, which are respectively arranged at the four corners of the push plate 302b. With the arrangement of the nut 302g, the right end of the second screw rod 302f here is fixedly connected to the transmission plate 302d. Thus, when the nut 302g is rotated, the distance between the push plate 302b and the transmission plate 302d can be adjusted, so as to adjust the distance between the L-shaped plate 302c and the push plate 302b, and adjust the compression degree of the second spring 302h.

[0047] It should be noted that the setting of the sixth cylinder 304j can drive the first slide block 304d to move left and right, so that the cap 304h is misaligned with the workpiece 104 to be processed, facilitating the picking and placing of larger workpieces 104 to be processed. At the same time, the setting of the shifting rod 304l and the third spring 304n enables the first slide block 304d to move a small distance, facilitating the left and right movement together with the workpiece 104 to be processed at the lower end. When the cap 304h abuts against the workpiece 104 to be processed, the wedge-shaped block 305e contacts the resisting plate 305b, so that the wedge-shaped block 305e and the resisting plate 305b can move synchronously, and the overall movement stability is better.

[0048] During use, during the automatic feeding process, first, the third motor 301b starts, driving the first screw 301c to rotate, causing the bearing seat 301e to move, the transmission plate 302d to move, driving the sliding seat 103 to move, and adjusting the center point of the opening of the long cylinder 201b to be collinear with the center point of the outer diameter of the main shaft 201d. Then, the nut 302g is rotated to adjust the extrusion degree of the third spring 304n. When the grinding head 201e and the workpiece to be machined 104 rotate, the second cylinder 302a starts and continuously expands and contracts. When the second cylinder 302a extends, it drives the push plate 302b to move to the right, and through the second spring 302h, the L-shaped plate 302c moves to the right, and the transmission plate 302d moves to the right. The significance of adjusting the compression degree of the second spring 302h here is that when the extrusion of the second spring 302h is small, when the second cylinder 302a extends, since the second spring 302h still has a large compression amount, when the second cylinder 302a extends, the second spring 302h is compressed by a certain amount, causing the transmission plate 302d to move a smaller distance. When the extrusion of the second spring 302h is large, when the push plate 302b moves, the transmission plate 302d will move, causing the transmission plate 302d to move a larger distance. Thus, with just an ordinary second cylinder 302a (resulting in lower numerical control requirements, simpler operation, and a lower cost for the ordinary second cylinder 302a), in cooperation with the rotation of the nut 302g, the adjustment of the moving distance of the transmission plate 302d can be achieved, thereby adapting to the use of workpieces to be machined 104 of different sizes;

[0049] Before the second cylinder 302a expands and contracts to achieve feeding, the sixth cylinder 304j shortens, and through transmission, the cap 304h moves to directly above the workpiece to be machined 104. During this process, the first sliding seat 304d slides on the first slide rail 304c for guiding. Then, the third cylinder 304a shortens, causing the lifting seat 304b to move downward, driving the first sliding seat 304d to move downward. Thus, the fourth cylinder 304e descends, driving the lifting frame 304f to descend. When the cap 304h abuts against the workpiece to be machined 104, the fourth cylinder 304e extends to clamp the cap 304h tightly. At this time, there is a certain distance between the grinding head 201e and the workpiece to be machined 104. Then, the fifth cylinder 304g extends to press the cap 304h downward, causing the workpiece to be machined 104 to move downward, and the sliding cylinder 202f to move downward, driving the workpiece to be machined 104 to cooperate with the grinding head 201e. The cooperation between the fourth cylinder 304e and the fifth cylinder 304g here makes the division of labor more detailed, facilitating the control of the distance. At the same time, the stroke is larger, facilitating the machining of workpieces to be machined 104 of different sizes;

[0050] During the movement of the transmission plate 302d, on the one hand, the sliding seat 103 is driven by the first connecting plate 303a, and on the other hand, the strip-shaped seat 303d is driven by the second connecting plate 303b, causing the vertical plate 305a to move and the abutting plate 305b to move. When the cap 304h cooperates with the workpiece 104 to be processed, the wedge block 305e abuts against the abutting plate 305b. The thickness of the abutting plate 305b and the wedge block 305e is sufficient so that when the cap 304h moves up and down, there will be no limit on the separation of the abutting plate 305b and the wedge block 305e. After the abutting plate 305b abuts against the wedge block 305e, it can drive the second sliding seat 305c to move synchronously with the sliding seat 103 at the lower end. Since the second sliding seat 305c cooperates with the second slide rail 305d and the second slide rail 305d is arranged on the first sliding seat 304d, when the second sliding seat 305c moves, it drives the first sliding seat 304d to move, enabling the overall linkage and avoiding the misalignment between the cap 304h and the workpiece 104 to be processed.

[0051] In summary, by setting the feeding component 300, feeding can be achieved in the left-right direction and the up-down direction, which is convenient for grinding. During the feeding process, the first spring 204f, the third spring 304n, etc. can achieve elastic feeding, avoiding excessive extrusion between the grinding head 201e and the workpiece 104 to be processed, causing excessive wear of the grinding head 201e and extending the service life of the grinding head 201e.
