DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0020] Example like Figures 1 to 8 As shown, the present invention provides a new type of polishing process device for the triangle of an underwear machine, including a base plate 1, on which a material moving component 2, a grinding component 3 and a lifting platform 4 are fixedly installed, a rotating component 5 is provided on the top of the lifting platform 4, and a supporting cylinder 8 for driving the rotating component 5 to slide is fixedly installed on the top of the lifting platform 4, a locking chuck 6 is provided on the top of the rotating component 5, and a workpiece 7 to be processed is placed on the top of the locking chuck 6, and the material moving component 2 and the grinding component 3 are both arranged on the outer periphery of the lifting platform 4 along the circumferential direction of the locking chuck 6.

[0021] As a further explanation of the embodiments of the present invention, in the prior art, the polishing step is particularly important in the production process of the underwear machine triangle, but the underwear machine triangle is an irregular triangular protrusion distributed on the annular frame. When using the traditional polishing process to polish this annular component, the traditional polishing brush roller cannot always fit the surface of the underwear machine triangle for grinding, or can only perform single-sided polishing on the top of the underwear machine triangle, which easily leads to polishing dead angles, resulting in insufficient surface accuracy of the underwear machine triangle. In the process of using this underwear machine triangle to produce underwear, problems such as snagging and wear that lead to material waste are very likely to occur. In this embodiment, after the workpiece 7 to be processed (the workpiece 7 to be processed in this embodiment is the underwear machine triangle) is fixed and moved to the top of the locking chuck 6 by the material transfer component 2, the lifting platform 4 is started to raise the locking chuck 6 to fit with the bottom of the workpiece 7 to be processed, and then the fixation of the material transfer component 2 is released, and then the workpiece 7 to be processed is adjusted to be coaxial with the locking chuck 6 by the locking chuck 6, and then the workpiece 7 to be processed is fixed on the locking chuck 6. When the locking chuck 6 and the material transfer component 2 are connected and fixed to the workpiece 7, the lifting platform 4 is always in an ascending working state. When the workpiece 7 to be processed is fixed on the locking chuck 6, and the lifting platform 4 raises the workpiece 7 to fit with the grinding component 3, the grinding component 3 and the rotating component 5 are used to fix the workpiece 7. Cooperate with each other to grind the top triangle of the workpiece 7 along the circumferential direction of the workpiece 7. After grinding, the locking chuck 6 and the workpiece 7 are rotated 90 degrees by the rotating component 5 so that the locking chuck 6 and the workpiece 7 are in a vertical state. The inner ring side wall and the outer ring side wall of the workpiece 7 are grinded in cooperation with the grinding component 3 through the lifting platform 4 and the supporting cylinder 8. After grinding, the workpiece 7 is reset by the rotating component 5 and the supporting cylinder 8 to release the restriction of the locking chuck 6 on the workpiece 7. After the workpiece 7 is fixed by the material moving component 2, the lifting platform 4 is started to descend to make the workpiece 7 disengage from the locking chuck 6. The workpiece 7 is moved out by the material moving component 2 to complete the grinding operation process of the locking chuck 6. In this embodiment, through the cooperation between the lifting platform 4 and the rotating assembly 5, the workpiece 7 to be processed can contact the grinding assembly 3 in both horizontal and vertical postures, thereby forming an all-round grinding of the top and the inner and outer walls of the workpiece 7 to be processed, effectively improving the overall flatness of the workpiece 7 to be processed after grinding.

[0022] As a preferred solution provided by a new type of polishing process device for the triangle of an underwear machine, the rotating component 5 includes a mounting base 51 slidably mounted on the top of the lifting platform 4, the output end of the top support cylinder 8 is fixedly connected to the side wall at the bottom of the mounting base 51, a placement box 52 is rotatably mounted on the top of the mounting base 51, and a first motor 53 for driving the placement box 52 to rotate is fixedly mounted on the side wall of the mounting base 51.

[0023] As a further explanation of an embodiment of the present invention, in this embodiment, the placement box 52 is driven to rotate by the first motor 53, and the locking chuck 6 rotatably connected to the top of the placement box 52 rotates with the placement box 52, while changing the inclination angle of the workpiece 7 to be processed. After the placement box 52 rotates by a preset angle, the workpiece 7 to be processed is in a vertical state and contacts with the grinding component 3, thereby achieving the effect of changing the contact state of the workpiece 7 to be processed and the grinding component 3.

[0024] As a preferred solution provided by a new type of polishing process device for the triangle of an underwear machine, the locking chuck 6 includes a pad 61 rotatably mounted on the top of the placement box 52, a cover plate 62 is fixedly mounted on the pad 61, a circular plate 63 is rotatably mounted between the cover plate 62 and the pad 61, a plurality of arc grooves 631 are opened on the circular plate 63, and a limiting column 64 is slidably installed in the arc groove 631, a plurality of straight grooves 621 corresponding to the arc grooves 631 are opened on the cover plate 62, and the limiting column 64 is slidably installed in the straight groove 621, a second motor 65 is fixedly mounted on the top of the cover plate 62, and the output end of the second motor 65 passes through the cover plate 62 and is fixedly connected to the circular plate 63.

[0025] As a further explanation of the embodiment of the present invention, in this embodiment, the working principle of the locking chuck 6 is that the circular plate 63 is driven to rotate by the second motor 65. Since each limiting column 64 is slidably installed in the arc groove 631 and the straight groove 621, when the circular plate 63 rotates, multiple limiting columns 64 are affected by the rotation of the circular plate 63 and move along the preset direction of the straight groove 621 to approach or move away from the inner ring wall of the workpiece 7 to be processed. Through the movement and adjustment of multiple limiting columns 64, the workpiece 7 to be processed is adjusted to be coaxial with the locking chuck 6 and is resisted by multiple limiting columns 64, so that the workpiece 7 to be processed is fixed on the locking chuck 6. Using the locking chuck 6 as a fixing device further expands the scope of application of the device, and adjusts the position of the workpiece 7 to be processed on the locking chuck 6 while fixing it, so that the contact between the workpiece 7 to be processed and the grinding assembly 3 during the rotational grinding process is more stable, thereby ensuring that the grinding assembly 3 can always be in contact with the inner and outer ring walls of the workpiece 7 to be processed, so that the coverage completeness of the polishing operation is further improved.

[0026] As a preferred solution provided by a new type of polishing process device for a cam of an underwear machine, a third motor 54 is fixedly installed in the placement box 52 , and an output end of the third motor 54 is fixedly connected to the pad 61 .

[0027] As a further illustration of an embodiment of the present invention, in this embodiment, while the locking chuck 6 is driven to rotate by the third motor 54, the workpiece 7 fixedly mounted on the locking chuck 6 also rotates, so that the polishing assembly 3 can perform polishing operations in all directions along the circumferential direction of the workpiece 7.

[0028] As a preferred solution provided by a new type of polishing process device for the triangle of an underwear machine, the grinding assembly 3 includes a support frame 31 fixedly installed on the base plate 1, a mounting groove 311 is opened on the top of the support frame 31, a guide rod 32 is fixedly installed in the mounting groove 311, a support plate 33 is slidably sleeved on the bottom of the guide rod 32, a fourth motor 34 is fixedly installed on the support plate 33, an outer fixed cover of the fourth motor 34 is provided, the output end of the fourth motor 34 is extended into the guide rod 32 and is fixedly connected to a grinding brush roller 35, a groove is opened on the side wall of the guide rod 32 for avoiding the output end of the fourth motor 34, a first spring 36 is sleeved on the guide rod 32, and the two ends of the first spring 36 are respectively pressed against the top of the mounting groove 311 and the top of the fourth motor 34.

[0029] As a further explanation of the embodiment of the present invention, in this embodiment, after the grinding brush roller 35 first contacts the workpiece 7 to be processed, the lifting platform 4 continues to drive the workpiece 7 to be processed to rise, so that the grinding brush roller 35 and the fourth motor 34 slide axially along the guide rod 32 while compressing the first spring 36. The elastic force generated by the deformation of the first spring 36 keeps the grinding assembly 3 and the workpiece 7 to be processed in a connected state, so that when the workpiece 7 to be processed rotates along the circumferential direction of the locking chuck 6, even if the raised part on the workpiece 7 to be processed repeatedly supports the grinding brush roller 35, the grinding brush roller 35 will not be separated from the workpiece 7 to be processed.

[0030] As a preferred solution provided by a new polishing process device for a cam of an underwear machine, an extended brush roller 37 is sleeved on the end of the grinding roller brush.

[0031] As a further explanation of the embodiment of the present invention, in this embodiment, while the grinding brush roller 35 is grinding the top protrusion of the workpiece 7 to be processed, the extended brush roller 37 is grinding the inner ring bottom surface of the workpiece 7 to be processed. Specifically, the diameter of the extended brush roller 37 is larger than that of the grinding brush roller 35, so the grinding range of the extended brush roller 37 is also improved compared with the grinding brush roller 35. When the grinding brush roller 35 is grinding the top of the workpiece 7 to be processed, the extended brush roller 37 located at the front end of the grinding brush roller 35 enters the inner ring of the workpiece 7 to be processed and grinds the inner ring bottom surface of the workpiece 7 to be processed, so that the grinding efficiency range and grinding efficiency of the grinding assembly 3 are further improved.

[0032] As a preferred solution provided by a new type of polishing process device for the triangle of an underwear machine, the material moving component 2 includes a mounting bracket 21 fixedly mounted on the base plate 1, a rotating shaft 22 is rotatably mounted in the mounting bracket 21, a fifth motor 23 for driving the rotating shaft 22 to rotate is fixedly mounted on the top of the mounting bracket 21, an extension plate 24 is directional and slidably sleeved on the rotating shaft 22, a vertical plate 25 is fixedly mounted on the bottom of the extension plate 24, a slide groove 241 is opened on the side wall of the extension plate 24, a push rod 26 is slidably mounted in the slide groove 241, a limiting cylinder 27 is fixedly mounted on the side wall of the vertical plate 25, the output end of the limiting cylinder 27 passes through the vertical plate 25 and is fixedly connected to the push rod 26, a second spring 28 is sleeved on the rotating shaft 22, and the two ends of the second spring 28 respectively press against the inner wall of the top of the mounting bracket 21 and the top of the extension plate 24.

[0033] As a further explanation of the embodiment of the present invention, in this embodiment, the working principle of the material moving assembly 2 is: the limiting cylinder 27 drives the push rod 26 to slide so that the push rod 26 can be telescopically adjusted, so that the push rod 26 and the vertical plate 25 are respectively located at the inner circle and outer circle of the workpiece 7 to be processed, and when the locking chuck 6 is raised to fit with the bottom of the vertical plate 25 by the lifting platform 4, the limiting cylinder 27 is started to shrink, and when the push rod 26 shrinks with the limiting cylinder 27, the push rod 26 contacts the inner circle wall of the workpiece 7 to be processed, and drives the workpiece 7 to be processed to move closer to the vertical plate 25 until the outer circle wall of the workpiece 7 to be processed contacts the side wall of the vertical plate 25, and the push rod 26 cooperates with the vertical plate 25 to clamp the inner and outer circle walls of the workpiece 7 to be processed, thereby fixing the workpiece 7 to be processed, and vice versa. In addition, when the push rod 26 and the vertical plate 25 are in an unlocked state with the workpiece 7 to be processed, the lifting platform 4 drives the locking chuck 6 to support the vertical plate 25 upward, and when the limiting cylinder 27 drives the extension plate 24 to slide axially upward along the rotating shaft 22 and compresses the second spring 28, the push rod 26 and the vertical plate 25 do not contact any point of the workpiece 7 to be processed, and will not cause any interference to the grinding operation of the workpiece 7 to be processed, and when the workpiece 7 to be processed rotates with the rotating component 5, the fifth motor 23 can drive the rotating shaft 22 to rotate, so that the extension plate 24 can avoid it in advance, so that the extension plate 24 will not appear in the travel path of the workpiece 7 to be processed. When the workpiece 7 is clamped and fixed by the support rod 26 and the vertical plate 25, the fifth motor 23 is started to drive the rotating shaft 22 to rotate, so that the clamped workpiece 7 to be processed rotates along the circumferential direction of the rotating shaft 22, and can be disengaged from the locking chuck 6. As a further preferred scheme of this embodiment, a discharging device and a collecting device are arranged on both sides of the mounting bracket 21, which are used to supply the workpiece 7 to be processed to the material transfer assembly 2 and collect the finished workpieces after polishing, so as to form a complete triangle polishing operation process of the underwear machine.

[0034] As a preferred solution provided by a new polishing process device for a cam of an underwear machine, a side wall at the top of the rotating shaft 22 is provided with an avoidance groove 221 , and a limit block 29 for sliding in the avoidance groove 221 is fixedly installed in the extension plate 24 .

[0035] As a further illustration of the embodiment of the present invention, in the present embodiment, the extension plate 24 is directional-slidably connected to the rotating shaft 22 through the limit block 29. When the vertical plate 25 is supported upward by the locking chuck 6 to compress the second spring 28, the extension plate 24 slides upward along the preset direction of the avoidance groove 221 through the limit block 29, so that the vertical plate 25 and the push rod 26 are always in the outer circle and inner circle of the workpiece 7 to be processed. When the polishing of the workpiece 7 to be processed is completed, the locking chuck 6 descends with the lifting platform 4 and releases the fixed connection state with the workpiece 7 to be processed. The elastic force generated by the deformation of the second spring 28 resists the extension plate 24, so that the vertical plate 25 at the bottom of the extension plate is always in contact with the top of the locking chuck 6. At this time The limiting cylinder 27 drives the push rod 26 to contract and cooperate with the vertical plate 25 to clamp and fix the workpiece 7 to be processed. After the locking chuck 6 continues to descend a preset distance with the lifting platform 4, the extension plate 24 slides downward to the preset minimum value of the avoidance groove 221, so that the vertical plate 25 cannot continue to move downward to fit the locking chuck 6. The fifth motor 23 then drives the rotating shaft 22 to rotate. The extension plate 24 is restricted by the limit block 29 and rotates together with the rotating shaft 22, and the clamped workpiece 7 to be processed is offset to the top of the locking chuck 6, thereby achieving the effect of detaching from the locking chuck 6 and unloading. Conversely, the workpiece 7 to be processed fixed by the vertical plate 25 and the push rod 26 is rotated and offset to the top of the locking chuck 6 for loading.
