DETAILED DESCRIPTION

[0033] The following will refer to the attached Figures 1 to 11 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0034] A grinding device for iron chain processing with a limiting structure, as shown in the attached Figure 1 To Attachment Figure 3 As shown, it comprises a polishing box 1, a cavity 2 is opened in the polishing box 1, a driving motor 3 is fixedly installed at the bottom of the cavity 2; a driving shaft 4 is installed at the output end of the driving motor 3; a cross 5 is fixedly installed at the upper end of the driving shaft 4; an annular cylinder 6 is fixedly installed on the outer periphery of the cross 5; an inner gear ring 7 is slidably installed on the inner wall of the annular cylinder 6; six groups of limit assemblies 8 are installed at equal intervals on the inner side of the annular cylinder 6 and through the annular cylinder 6; each group of the limit assemblies 8 is installed on the annular cylinder 6. Limit drive assemblies 9 are installed at positions corresponding to the positioning assemblies 8; an annular plate 10 is fixedly installed on the inner wall of the cavity 2 at positions corresponding to the limiting assemblies 8; clamping assemblies 11 are installed on the annular plate 10 at positions corresponding to each group of the limiting assemblies 8; a clamping drive assembly 12 is installed on one side of each group of the clamping assemblies 11; a grinding assembly 13 is installed on the top of the grinding box 1; a mounting frame 14 is fixedly installed on the inner gear ring 7; and a pressing assembly 15 is installed on the mounting frame 14.

[0035] During specific use, the iron chain to be polished is first put on the outside of the six groups of limit assemblies 8, and then the pressing assembly 15 is adjusted to make the lower end of the pressing assembly 15 inserted into the driving shaft 4, and the driving motor 3 is turned on (the driving motor 3 is connected to a power supply and a controller). The driving motor 3 drives the driving shaft 4 to rotate, and further drives the pressing assembly 15 to rotate. Further, the pressing assembly 15 drives the mounting frame 14 to rotate. Since the mounting frame 14 is fixedly connected to the inner gear ring 7, the inner gear ring 7 is driven to rotate synchronously. The inner gear ring 7 drives the limit drive assembly 9 to adjust the six groups of limit assemblies 8, so that the iron chain to be polished is completely fitted with the edge of the six groups of limit assemblies 8; then the clamping drive assembly 12 is adjusted to further enable the clamping assembly 11 to clamp and fix the iron chain to be polished, thereby facilitating the polishing assembly 13 to polish it.

[0036] As attached Figure 7 To Attachment Figure 8 As shown, the limit assembly 8 includes a limit plate mounting hole 16 arranged on the annular cylinder 6; a limit plate 17 is installed in the limit plate mounting hole 16; a limit plate slide bar 18 is fixedly installed at the bottom of the limit plate 17; a limit plate slide hole 19 adapted to the limit plate slide bar 18 is opened below the limit plate mounting hole 16, and the limit plate slide hole 19 is connected to the limit plate mounting hole 16; the limit plate slide bar 18 is slidably installed in the limit plate slide hole 19; a limit arc baffle 20 is fixedly installed at the outer end of the limit plate 17; and a limit protrusion 21 is fixedly connected to the middle of the limit arc baffle 20.

[0037] During specific use, the iron chain to be polished is first put on the outside of the six limit plates 17, and the limit protrusion 21 is located in the iron ring of the iron chain to be polished, and then the limit drive component 9 is adjusted to further drive the limit plate slide bar 18 to slide in the limit plate slide hole 19, thereby driving the limit plate 17 to slide, so that the iron chain to be polished is completely fitted with the edges of the six limit plates 17; the limit arc baffle 20 is set to prevent the limit plate 17 from being removed from the limit plate mounting hole 16.

[0038] As attached Figure 7 To Attachment Figure 8As shown, each group of the limit drive assembly 9 includes a support plate 22 fixedly mounted on the inner wall of the annular cylinder 6; a limit drive gear shaft 23 is rotatably mounted on the support plate 22; a limit drive gear 24 is fixedly mounted on the limit drive gear shaft 23; the upper part of the limit drive gear 24 is meshed with the inner gear ring 7; a limit drive rack 25 is fixedly mounted on the limit plate 17, and the limit drive rack 25 is located below the inner gear ring 7; the limit drive rack 25 is meshed with the lower part of the limit drive gear 24; a limit drive rack hole 26 for the limit drive rack 25 to pass through is opened on the side wall of the annular cylinder 6 at a position corresponding to the limit drive rack 25.

[0039] During specific use, by adjusting the pressing assembly 15, the lowermost end of the pressing assembly 15 is inserted into the driving shaft 4, and the driving motor 3 is turned on. The driving motor 3 drives the driving shaft 4 to rotate, and further drives the pressing assembly 15 to rotate. Further, the pressing assembly 15 drives the mounting frame 14 to rotate. Since the mounting frame 14 is fixedly connected to the inner gear ring 7, the inner gear ring 7 is driven to rotate synchronously. Since the upper part of the limit driving gear 24 is meshed with the inner gear ring 7, and the lower part of the limit driving gear 24 is meshed with the limit driving rack 25, the rotation of the inner gear ring 7 drives the limit driving gears 24 installed on the six support plates 22 to rotate, and further drives the limit driving The movable rack 25 slides in the limit drive rack hole 26. Since the limit drive rack 25 is fixedly mounted on the limit plate 17, when the limit drive rack 25 slides, it drives the limit plate 17 to slide as a whole, thereby achieving complete fit between the edges of the iron chain to be polished and the six limit drive gears 24; the inner gear ring 7 rotates clockwise to drive the six limit drive gears 24 to rotate clockwise, thereby driving the limit drive rack 25 and the limit plate 17 to slide in the direction close to the drive shaft 4; the inner gear ring 7 rotates counterclockwise to drive the six limit drive gears 24 to rotate counterclockwise, thereby driving the limit drive rack 25 and the limit plate 17 to slide in the direction away from the drive shaft 4.

[0040] As attached Fig. 9 As shown, the clamping assembly 11 includes a linear groove 27 arranged on the annular plate 10, and a clamping rack 28 is slidably installed in the linear groove 27; an arc-shaped grinding plate 29 is fixedly connected to the clamping rack 28 at one end close to the annular cylinder 6, and the upper end surface of the arc-shaped grinding plate 29 is flush with the upper end surface of the limit plate 17; the arc-shaped surface of the arc-shaped grinding plate 29 close to the limit plate 17 is a polished rough surface.

[0041] During specific use, by adjusting the clamping drive assembly 12, the clamping rack 28 is driven to slide in the linear slide groove 27, so that the arc-shaped grinding plate 29 clamps and fixes the iron chain to be ground, which facilitates the subsequent grinding assembly 13 to grind the iron chain.

[0042] As attached Figure 1 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 6 As shown, the clamping drive assembly 12 includes a clamping drive gear shaft 31 rotatably mounted on the annular plate 10; a clamping drive gear 32 is fixedly mounted on the upper end of the clamping drive gear shaft 31; the clamping drive gear 32 is meshed with its corresponding clamping rack 28; a clamping drive motor 34 is mounted on the lower end of one of the clamping drive gear shafts 31; and a synchronous transmission assembly 35 is mounted on the lower ends of six of the clamping drive gear shafts 31.

[0043] During specific use, the clamping drive motor 34 is turned on (the clamping drive motor 34 is connected to a power supply and a controller), and the clamping drive motor 34 drives the clamping drive gear shaft 31 connected thereto to rotate. Since the lower ends of the six clamping drive gear shafts 31 are equipped with a synchronous transmission assembly 35, the six clamping drive gear shafts 31 are driven to rotate synchronously and in the same direction. Since the clamping drive gear 32 is fixedly installed on the upper end of the clamping drive gear shaft 31, and a clamping rack 28 is meshed on one side of each clamping drive gear 32, the rotation of the clamping drive gear shaft 31 drives the clamping drive gear to rotate synchronously, further drives the clamping rack 28 to slide in the linear slide groove 27, and further drives the arc-shaped grinding plate 29 to move toward the direction close to the limit plate 17, thereby achieving the clamping and fixation of the iron chain to be ground. The clamping drive gear 32 rotates clockwise to drive the clamping rack 28 to move toward the limit plate 17, so as to clamp and fix the iron chain to be polished; the clamping drive gear 32 rotates counterclockwise to drive the clamping rack 28 to move away from the limit plate 17, so as to facilitate the removal of the iron chain.

[0044] As attached Figure 4 , Attachment Figure 6 As shown, the synchronous transmission assembly 35 includes a synchronous sprocket A 36 fixedly installed at the bottom ends of the six clamping drive gear shafts 31; and the synchronous sprocket A 36 is located above the clamping drive motor 34; synchronous sprockets B 37 are fixedly installed on four of the clamping drive gear shafts 31 (the synchronous sprocket B 37 is not installed on the two clamping drive gear shafts 31 at the left rear, that is, the clamping drive gear shaft 31 opposite to the clamping drive motor 34 and the clamping drive gear shaft 31 on its left side are not installed); and the synchronous sprocket B 37 is located above the synchronous sprocket A 35; a synchronous chain A 38 is provided on the outer sleeves of two adjacent synchronous sprockets A 35; and a synchronous chain B 39 is provided on the outer sleeves of two adjacent synchronous sprockets B 37.

[0045] During specific use, since the six clamping drive gear shafts 31 are fixedly installed with synchronous sprockets A 36, the clamping drive gear shaft 31 connected to the clamping drive motor 34 and the two clamping drive gear shafts 31 on the right and the one clamping drive gear shaft 31 on the left are fixedly installed with synchronous sprockets B 37, and the outer sleeves of the two adjacent synchronous sprockets A 35 are provided with synchronous chains A 38, and the outer sleeves of the two adjacent synchronous sprockets B 37 are provided with synchronous chains B 39, when the clamping drive motor 34 drives the clamping drive gear shaft 31 connected thereto to rotate, the remaining five clamping drive gear shafts 31 can rotate synchronously in the same direction.

[0046] As attached Fig.10 As shown, the grinding assembly 13 includes a grinding motor 40 fixedly mounted on the top of the grinding box 1; a grinding drive screw 41 is installed at the output end of the grinding motor 40; a grinding drive threaded block 42 is threadedly mounted on the grinding drive screw 41; a grinding block connecting rod 43 is fixedly mounted at the bottom of the grinding drive threaded block 42; and a grinding block 44 is fixedly mounted at the bottom of the grinding block connecting rod 43.

[0047] During specific use, the grinding motor 40 is turned on (the grinding motor 40 is connected to a power supply and a controller), and the grinding motor 40 drives the grinding drive screw 41 to rotate, thereby driving the grinding drive threaded block 42 to move up and down, so as to facilitate the adjustment of the grinding block 44 to a position that fits the iron chain to be polished.

[0048] As attached Fig.11 As shown, the pressing assembly 15 includes a pressing hole 46 with a groove 45 opened at the center of the mounting frame 14; a pressing rod 48 with a convex strip 47 is installed in the pressing hole 46; a pressing plate 49 is fixedly installed on the top of the pressing rod 48; a pressing spring 50 is provided on the outer sleeve of the pressing rod 48; one end of the pressing spring 50 is fixedly connected to the pressing plate 49; the other end of the pressing spring 50 is fixedly connected to the upper end surface of the mounting frame 14.

[0049] As attached Fig. 9 , Attachment Fig.11 As shown, a pressing rod accommodating chamber 51 adapted to the pressing rod 48 is opened on the driving shaft 4 (the interface shape of the pressing rod accommodating chamber is the same as that of the pressing rod); sliding grooves 52 for the clamping racks 28 to slide are opened on the grinding box 1 at positions corresponding to the six clamping racks 28.

[0050] When in use, the pressing plate 49 is pressed downward to insert the lower end of the pressing rod 48 into the pressing rod accommodating chamber 51 in the driving shaft 4, and the driving motor 3 is turned on. The driving shaft 4 can drive the pressing rod 48 to rotate. Since the pressing hole 46 has a groove 45, the rotation of the pressing rod 48 can drive the mounting frame 14 to rotate. The mounting frame 14 is fixedly connected to the inner gear ring 7, thereby further driving the inner gear ring 7 to rotate synchronously. Since the upper part of the limit driving gear 24 is meshed with the inner gear ring 7, and the lower part of the limit driving gear 24 is meshed with the limit driving rack 25, the inner gear ring 7 is rotated. The rotation of the ring 7 drives the limit drive gear 24 rotatably installed on the six support plates 22, and further drives the limit drive rack 25 to slide in the limit drive rack hole 26. Since the limit drive rack 25 is fixedly installed on the limit plate 17, the limit drive rack 25 drives the limit plate 17 to slide as a whole when it slides, so that the iron chain to be polished is completely fitted with the edges of the six limit plates 17; then turn off the drive motor 3 and release the pressing plate 49, so that the pressing rod 48 moves out of the pressing rod accommodating chamber 51 under the elastic force of the pressing spring 50.

[0051] Since the cross 5 is fixedly mounted on the upper end of the driving shaft 4, the annular cylinder 6 is fixedly mounted on the outer circumference of the cross 5; the driving motor 3 is turned on, the driving shaft 4 drives the cross 5 to rotate, and further the annular cylinder 7 rotates, thereby driving the iron chain to be polished that is in contact with the edge of the limiting plate 17 to rotate, thereby realizing the polishing of the iron chain by the polishing block 44 and the arc-shaped polishing plate 29.

[0052] As attached Fig.11 As shown, an annular groove 53 is opened on the inner wall of the annular cylinder 6; a slip ring 54 is fixedly installed on the bottom of the outer wall of the inner gear ring 7; the slip ring 54 is slidably installed in the annular groove 53; when in use, the mounting frame 14 can drive the inner gear ring 7 to slide in the annular groove 53.
