Description

Technical Field

[0001] This utility model relates to the field of stator processing technology, and in particular to a stator grinding device. Background Technology

[0002] Traditional stator machining equipment typically uses direct clamping to fix the stator when grinding its outer wall. Because the clamping components are in close contact with the stator's outer wall, they physically obstruct the workpiece during grinding, preventing effective grinding of that area. This results in untreated areas on the stator's outer wall, severely impacting key precision indicators such as overall flatness, cylindricity, and surface roughness. Removing the stator before grinding these untreated areas and then grinding them separately is not only cumbersome, requiring repositioning and re-clamping the stator, increasing processing time and labor costs, but also makes it difficult to maintain consistent clamping accuracy during multiple clamping operations, easily introducing new machining errors and further reducing the stator's machining quality. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, the purpose of this utility model is to propose a stator grinding device that can solve the problem that existing grinding devices cannot grind comprehensively and are prone to processing errors.

[0005] To achieve the above objectives, this utility model proposes a stator grinding device, including a processing plate, an upper mounting plate below the processing plate, six corresponding upper slide rails and positioning grooves on the upper mounting plate and the processing plate, slide rods slidably connected to the inner walls of the upper slide rails and positioning grooves, a lower mounting plate below the upper mounting plate, an upper motor and a lower motor fixedly connected to the center of the upper mounting plate and the lower mounting plate respectively, lead screws fixedly connected to the drive ends of the upper motor and the lower motor respectively, upper brackets and lower brackets threadedly connected to the outer walls of the two lead screws respectively, three first uprights and second uprights slidably connected to the top ends of the upper brackets and the lower brackets respectively, clamping columns installed at the top ends of the first uprights and the second uprights, and the clamping columns slidably connected to the slide rods.

[0006] The stator grinding device of this utility model can adjust the height of the upper and lower brackets through the upper motor, lower motor and lead screw respectively. With the cooperation of the first and second uprights, the height of the clamping columns can be adjusted, so that the two sets of clamping columns can be interchanged at the height of the slide bar. With the adjustment of the slide bar position, the clamping columns can clamp different positions on the outer wall of the stator. The device can ensure that the stator is clamped and fixed for grinding work, and can also perform comprehensive grinding work on the outer wall of the stator, avoiding the need to remove the stator for repositioning, which is prone to errors.

[0007] In addition, the stator grinding apparatus proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, a support plate is installed at the center of the processing plate, and support grooves are provided on the inner walls of the upper slide and the positioning groove. A limiting block matching the support groove is installed on the slide rod.

[0009] Specifically, the two lead screws are connected by a connecting plate, and the connecting plate is rotatably connected to the lead screws.

[0010] Specifically, a base plate is provided below the lower mounting plate, and a frame rod is fixedly connected to the base plate. The frame rod is fixedly connected to the bottom end of the upper mounting plate. A grinding assembly is installed on one side of the base plate, and one of the frame rods is connected to the connecting plate by a horizontal plate.

[0011] Specifically, the outer wall of the upper mounting plate is fixedly connected with several side plates corresponding to the slide rod, and a drive telescopic rod is installed on one side of the side plate, with one end of the drive telescopic rod fixedly connected to one side of the slide rod.

[0020] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] A stator grinding device according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a stator grinding device according to an embodiment of the present invention may include a processing plate 1, an upper mounting plate 2 below the processing plate 1, six upper slide rails 12 and positioning grooves 211 corresponding to each other on the upper mounting plate 2 and the processing plate 1, slide rods 27 slidably connected to the inner walls of the upper slide rails 12 and the positioning grooves 211, and a lower mounting plate 21 below the upper mounting plate 2.

[0023] Among them, an upper motor 22 and a lower motor 23 are fixedly connected to the center of the upper mounting plate 2 and the lower mounting plate 21, respectively. The drive ends of the upper motor 22 and the lower motor 23 are fixedly connected to lead screws 24, and the outer walls of the two lead screws 24 are respectively threaded with an upper bracket 25 and a lower bracket 26.

[0024] It should be noted that, in this embodiment, the upper motor 22 and the lower motor 23 are vertically corresponding, the upper bracket 25 is above the lower bracket 26, and the upper bracket 25 and the lower bracket 26 correspond to the upper slide rail 12 and the positioning groove 211.

[0025] Among them, the top ends of the upper bracket 25 and the lower bracket 26 are respectively slidably connected to three first uprights 251 and second uprights 261. The top ends of the first uprights 251 and the second uprights 261 are each equipped with a clamping post 28, and the clamping post 28 is slidably connected to the slide rod 27.

[0026] It should be noted that the first upright 251 and the second upright 261 described in this embodiment are equidistantly distributed, and the first upright 251 and the second upright 261 correspond to the slide bar 27 respectively.

[0027] Specifically, the processing plate 1 is used to support the stator. The stator is placed on the processing plate 1, allowing the processing plate 1 to correspond vertically with the upper mounting plate 2 below it. This ensures that the upper slide rails 12 and positioning grooves 211 on the processing plate 1 and upper mounting plate 2 are vertically aligned. The upper slide rails 12 and positioning grooves 211 are equidistantly distributed, forming groups of three. The sliding rods 27, slidably connected to the inner walls of the upper slide rails 12 and positioning grooves 211, can be adjusted in position. This allows the clamping posts 28, slidably connected to the sliding rods 27, to slide up and down, clamping the stator against the outer wall. The six... The slide rods 27 are arranged in groups of three, with the bottoms of the two groups of slide rods 27 supported by the upper bracket 25 and the lower bracket 26, respectively. The upper bracket 25 and the lower bracket 26 are positioned between the upper mounting plate 2 and the lower mounting plate 21, allowing the first upright 251 and the second upright 261, which are slidably connected on the upper bracket 25 and the lower bracket 26, to correspond vertically with the two groups of slide rods 27. At this time, the clamping column 28 installed at the top of the slide rod 27 is rotatably connected to the top of the first upright 251 and the second upright 261, allowing the clamping column 28 to slide up and down to adjust its height on the slide rod 27, while simultaneously providing support. Supported by the slide bar 27, the clamping column 28 clamps the outer wall of the stator, thus fixing the positioning support at the center of the processing plate 1. This ensures the stability of the stator during grinding. During grinding, the stator is clamped by a set of clamping columns 28. The height of the two sets of clamping columns 28 can be driven by the upper motor 22 and the lower motor 23 to drive the lead screw 24. The upper bracket 25 and the lower bracket 26 are threadedly connected to the lead screw 24, allowing the rotation of the lead screw 24 to adjust the height of the upper bracket 25 and the lower bracket 26, thereby adjusting the height of the two sets of clamping columns 28. The device is designed so that when in use, one set of clamping columns 28 can retract into the slide bar 27, while another set protrudes to clamp the stator. After grinding the unclamped area, the clamping columns 28 that were originally clamping the stator can be moved downwards, while the clamping columns 28 that were originally in the slide bar 27 can be moved upwards simultaneously. This allows the other set of clamping columns 28 to clamp the ground area of ​​the stator, and the device can perform grinding operations on the outer wall that was originally limited by the first set of clamping columns 28. This ensures that the device can clamp and fix the stator for grinding while simultaneously performing comprehensive grinding operations on the outer wall of the stator.

[0028] In one embodiment of this utility model, such as Figures 1-4 As shown, a support plate 11 is installed at the center of the processing plate 1, and support grooves 13 are provided on the inner walls of the upper slide rail 12 and the positioning groove 211. A limiting block 271 matching the support groove 13 is installed on the slide rod 27.

[0029] It should be noted that the limiting block 271 described in this embodiment is engaged with the inner wall of the support groove 13.

[0030] Specifically, when the slide rod 27 slides on the inner wall of the upper slide rail 12 and the positioning groove 211, the slide rod 27 can be horizontally limited on the inner wall of the upper slide rail 12 and the positioning groove 211, so that the slide rod 27 can slide horizontally and drive the clamping column 28 to move, thereby clamping the outer wall of the stator by the clamping column 28.

[0031] In one embodiment of this utility model, such as Figures 1-4 As shown, the two lead screws 24 are connected by a connecting plate 241, and the connecting plate 241 is rotatably connected to the lead screws 24.

[0032] It should be noted that the connecting plate 241 described in this embodiment is located at the connection point of the two lead screws 24.

[0033] Specifically, by having two adjustable screws 24, one for the upper bracket 25 and the other for the lower bracket 26, which are vertically aligned and connected by a connecting plate 241, the screws 24 are ensured to be vertical. This ensures that the screws 24 can adjust the upper bracket 25 and the lower bracket 26 vertically, thereby allowing the first upright 251 and the second upright 261 to adjust the height of the two sets of clamping columns 28 respectively.

[0034] In one embodiment of this utility model, such as Figures 1-4 As shown, a base plate 3 is provided below the lower mounting plate 21, and a support rod 31 is fixedly connected to the base plate 3. The support rod 31 is fixedly connected to the bottom end of the upper mounting plate 2. A grinding assembly 32 is installed on one side of the base plate 3, and one of the support rods 31 is connected to the connecting plate 241 through a horizontal plate 242.

[0035] It should be noted that the support rod 31 and the cross plate 242 described in this embodiment are misaligned with the upper bracket 25 and the lower bracket 26.

[0036] Specifically, the height of the connecting plate 241 can be fixed by connecting and fixing it to the outer wall of the bracket 31 installed on the base plate 3 through the horizontal plate 242, so that the height of the connecting plate 241 is fixed and it can connect and position the lead screw 24. The bracket 31 supports the height of the upper mounting plate 2, so that the upper mounting plate 2 and the processing plate 1 can be supported and erected above the base plate 3, so that the stator can be at an appropriate height to correspond to the grinding wheel used for grinding, and the outer wall of the stator can be ground under the action of the grinding assembly 32.

[0037] In one embodiment of this utility model, such as Figures 1-4As shown, several side plates 29 corresponding to the slide rod 27 are fixedly connected to the outer wall of the upper mounting plate 2. A drive telescopic rod 291 is installed on one side of the side plate 29, and one end of the drive telescopic rod 291 is fixedly connected to one side of the slide rod 27.

[0038] It should be noted that each side plate 29 and drive telescopic rod 291 described in this embodiment corresponds to a slide rod 27.

[0039] Specifically, the position of the slide rod 27 can be extended or retracted by the drive telescopic rod 291, so that the drive telescopic rod 291 can push one side of the slide rod 27, and the position of the slide rod 27 on the processing plate 1 and the upper mounting plate 2 can be adjusted, thereby allowing the two sets of clamping columns 28 to be adjusted in position and to fasten and clamp the outer wall of the stator.

[0040] In summary, the stator grinding device of this utility model, when in use, places the stator to be ground at the center of the processing plate 1. At this time, the upper motor 22 drives the lead screw 24 to rotate, causing the upper bracket 25 and the first upright 251 to move a set of clamping columns 28 upward. Meanwhile, the lower motor 23 drives the lead screw 24, causing the lower bracket 26 and the second upright 261 to move another set of clamping columns 28 downward. This allows the clamping columns 28, supported by the first upright 251, to be supported by the telescopic rod 291 on the slide rod 27. The device lowers the stator and clamps it onto the outer wall of the stator. After grinding the outer wall of the stator, the upper motor 22 and the lower motor 23 can control the height of the first upright 251 and the second upright 261 respectively, so that the positions of the two sets of clamping columns 28 can be interchanged. This allows the other set of clamping columns 28 to clamp the ground area of ​​the stator, and the device can perform grinding operations on the outer wall that was originally limited by the first set of clamping columns 28. Thus, the device can ensure that while clamping and fixing the stator for grinding, it can also perform comprehensive grinding operations on the outer wall of the stator.
