Description

Technical Field

[0001] The present application relates to the field of automatic processing, and in particular to an automatic groove milling device for a fluoroplastic annular workpiece. Background Art

[0002] Some annular workpieces, such as fluoroplastic sealing rings, fluoroplastic piston rings and other workpieces, need to be milled at both ends of the annular workpiece after processing. According to product requirements, four grooves are usually required to be milled, and a pair of grooves are milled on each of the two end faces of the annular workpiece. Specifically, a pair of first end face grooves are relatively opened on one end face of the annular workpiece, and a pair of second end face grooves are relatively opened on the other end face of the annular workpiece. Observe the axial projection surface of the annular workpiece to connect the midpoints of the two first end face grooves and the midpoints of the two second end face grooves. The above two lines intersect and the angle between them is 90 degrees.

[0003] When processing the first end face groove and the second end face groove in the prior art, the fluoroplastic annular workpiece is usually first sleeved on a cylindrical fixture, the fixture is clamped on a three-jaw chuck, and then the milling cutter is operated to mill the first end face groove on the end face of the fluoroplastic annular workpiece. When a pair of first end face grooves are processed, the staff needs to remove the fluoroplastic annular workpiece from the fixture, and then set the other end face of the fluoroplastic annular workpiece toward the milling cutter, re-sleeve it on the fixture, and then operate the milling cutter to process the second end face groove. When the end face groove of a fluoroplastic annular workpiece is processed, the staff will remove the processed fluoroplastic annular workpiece and repeat the above process to process the next fluoroplastic annular workpiece.

[0004] With respect to the above-mentioned related technologies, the inventors believe that when machining the end face groove of a fluoroplastic annular workpiece, the fluoroplastic annular workpiece needs to be manually clamped, and when milling grooves on the two end faces of the fluoroplastic annular workpiece, the same fluoroplastic annular workpiece needs to be clamped twice, resulting in a problem of low machining efficiency. Summary of the invention

[0005] In order to improve the end face groove processing efficiency of a fluoroplastic annular workpiece, the present application provides an automatic groove milling device for a fluoroplastic annular workpiece.

[0006] The present application provides an automatic groove milling device for a fluoroplastic annular workpiece, which adopts the following technical solution:

At this time, the clamping driving member drives the clamping member to move toward the workbench to clamp the fluoroplastic annular workpiece located in the processing area, and the first clamping member moves away from the processing area, and the second clamping member also moves away from the processing area. After the clamping member clamps the fluoroplastic annular workpiece, the first milling mechanism mills a groove on one end face of the fluoroplastic annular workpiece above the processing area, and the output end of the second milling mechanism passes through the processing groove and mills a groove on the other end face of the fluoroplastic annular workpiece below the processing area. When the milling is completed, the clamping driving member drives the clamping member to move away from the workbench, and the unloading mechanism can move the fluoroplastic annular workpiece processed in the processing area out of the processing area.

[0013] The first clamping member can move the fluoroplastic workpiece from the loading area to the processing area. The first clamping member and the second clamping member can cooperate with each other to position the fluoroplastic annular workpiece in the processing area. The pressing member can press the fluoroplastic annular workpiece so that the second milling mechanism can mill grooves on the end face of the fluoroplastic annular workpiece below the processing area. The first milling mechanism and the second milling mechanism can mill grooves on both end faces of the fluoroplastic annular workpiece at the same time.

[0039] The present application is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] The present application embodiment discloses an automatic groove milling device for a fluoroplastic annular workpiece. Figure 1The automatic milling groove equipment of the fluoroplastic annular workpiece includes a workbench 1, a feeding mechanism 2, a clamping mechanism 3, a pressing mechanism 4, a first milling mechanism 5 located above the workbench 1, a second milling mechanism 6 located below the workbench 1, and a feeding mechanism 7. A feeding area 11 and a processing area 12 are sequentially arranged on the workbench 1. The feeding mechanism 2 is used to transport the fluoroplastic annular workpiece to the feeding area 11. The clamping mechanism 3 is used to move the fluoroplastic annular workpiece located in the feeding area 11 to the processing area 12. The first milling mechanism 5 is used to mill grooves on the fluoroplastic annular workpiece above the workbench 1. The second milling mechanism 6 is used to mill grooves on the fluoroplastic annular workpiece below the workbench 1. The feeding mechanism 7 is used to move the fluoroplastic annular workpiece processed in the processing area 12 out of the processing area 12.

[0041] Reference Figure 1 and Figure 2 In order to enable the first milling mechanism 5 and the second milling mechanism 6 to simultaneously mill grooves on the two end faces of the fluoroplastic annular workpiece above and below the workbench 1, a structure is specifically but not restrictively proposed, in which a processing groove 13 is provided on the workbench 1, and the processing groove 13 runs through the top surface and the bottom surface of the workbench 1, and the loading area 11 and the processing area 12 are arranged above the processing groove 13 along the extension direction of the processing groove 13. The accommodating space 131 formed between the two side walls of the processing groove 13 parallel to its own extension direction is used for the output end of the second milling mechanism 6 to pass through. It is worth noting that the distance between the two side walls of the processing groove 13 parallel to its own extension direction is less than the diameter of the fluoroplastic annular workpiece to be milled.

[0042] The feeding mechanism 2 is used to transport the fluoroplastic annular workpiece to the feeding area 11. As an example, the feeding mechanism 2 includes a vibrating feeding tray 21 and a feeding track 22. One end of the feeding track 22 is connected to the vibrating feeding tray 21, and the other end is overlapped on the workbench 1. And one end of the feeding track 22 overlapped on the workbench 1 is located in the feeding area 11. The vibrating feeding tray 21 transports the fluoroplastic annular workpiece to the feeding area 11 through the feeding track 22.

[0043] For the above scheme, the slot milling equipment is also provided with a feeding controller and a first sensor 8 arranged on the workbench 1. The sensing area of ​​the first sensor 8 covers the feeding area 11, and the first sensor 8 is electrically connected to the feeding controller. The first sensor 8 is used to detect whether there is a fluoroplastic annular workpiece in the feeding area 11, and convert the detection result into a detection signal. The feeding controller is used to receive the detection signal and control the feeding mechanism 2 based on the detection signal. In different embodiments, the first sensor 8 can be a sensor of different types, as long as it can detect whether there is a fluoroplastic annular workpiece in the feeding area 11. As an example, the first sensor 8 is an optical fiber sensor. After the vibrating feeding tray 21 is started, the fluoroplastic annular workpiece is transported to the feeding track 22. After the feeding track 22 transports the fluoroplastic annular workpiece to the feeding area 11, the first sensor 8 detects that the fluoroplastic annular workpiece is transported to the feeding area 11. The first sensor 8 transmits the detection signal of the fluoroplastic annular workpiece to the feeding controller. Based on this detection signal, the feeding controller turns off the vibrating feeding tray 21 to suspend the feeding and turns on the vibrating feeding tray 21 after a specific time to continue the feeding. To further explain the specific time, after the fluoroplastic annular workpiece is moved to the loading area 11, it is also moved to the processing area 12 to process the end surface groove. The sum of the time required for the fluoroplastic annular workpiece to be moved from the loading area 11 to the processing area 12, the time for the end surface groove to be processed in the processing area 12, and the time for the unloading mechanism 7 to unload the workpiece in the processing area 12 is the time set by the specific time.

[0044] The clamping mechanism 3 pushes the fluoroplastic annular workpiece located in the loading area 11 to the processing area 12, and positions the fluoroplastic annular workpiece in the processing area 12. In different embodiments, the clamping mechanism 3 can be of different structures, as long as it can push the fluoroplastic annular workpiece to the processing area 12 and position the fluoroplastic annular workpiece in the processing area 12. As an example, the clamping mechanism 3 includes a first clamping member 31 and a second clamping member 32 arranged relatively on the workbench 1, and the first clamping member 31 is connected to a first driving member 33, the first driving member 33 drives the first clamping member 31 to move in the processing area 12, and the first clamping member 31 passes through the loading area 11. The second clamping member 32 is connected to a second driving member 34, and the second driving member 34 drives the second clamping member 32 to move toward the processing area 12. In different embodiments, the first driving member 33 can be a different device, and the second driving member 34 can also be a different device. As an example, the first driving member 33 and the second driving member 34 are both cylinders, and the first driving member 33 and the second driving member 34 are arranged opposite to each other. The piston rod of the first driving member 33 is arranged toward the second driving member 34, and the piston rod of the second driving member 34 is arranged toward the first driving member 33.

[0045] For the above scheme, specifically, the first clamping member 31 and the second clamping member 32 are both plate-shaped. The first clamping member 31 is provided with a first groove 311 relative to the surface of the second clamping member 32, and the first groove 311 is used to abut the circumferential surface of the fluoroplastic annular workpiece. The second clamping member 32 is provided with a second groove 321 relative to the surface of the second clamping member 32, and the second groove 321 is used to abut the circumferential surface of the fluoroplastic annular workpiece. In different embodiments, the first groove 311 can be of different shapes, and the second groove 321 can be of different shapes, as long as they can abut against the fluoroplastic annular workpiece. As an example, the first groove 311 and the second groove 321 are both semicircular grooves. The diameters of the semicircular grooves provided by the first clamping member 31 and the second clamping member 32 are equal to the diameters of the corresponding fluoroplastic annular workpiece. The first groove 311 and the second groove 321 are arranged in this way, which can not only form multiple contact points with the circumferential surface of the fluoroplastic annular workpiece, but also further realize surface-to-surface contact. When the first clamping member 31 pushes the fluoroplastic annular workpiece, the fluoroplastic annular workpiece can be better moved toward the processing area 12. When in the processing area 12, the first clamping member 31 and the second clamping member 32 are in multi-faceted contact with the fluoroplastic annular workpiece, which can better position the fluoroplastic annular workpiece in the processing area 12. The first clamping member 31 is detachably connected to the piston rod of the first driving member 33, and the second clamping member 32 is detachably connected to the piston rod of the second driving member 34. As an example, the first clamping member 31 is bolted to the piston rod of the first driving member 33, and the second clamping member 32 is bolted to the piston rod of the second driving member 34. With such an arrangement, the first clamping member 31 and the second clamping member 32 adapted thereto can be replaced when processing fluoroplastic annular workpieces of different specifications, and the diameters of fluoroplastic annular workpieces of different specifications are different.

[0046] Furthermore, the first clamping member 31 and the second clamping member 32 both move above the processing groove 13, in order to avoid interference between the first clamping member 31 and the output end of the second milling mechanism 6 in the processing groove 13, and also to avoid interference between the second clamping member 32 and the output end of the second milling mechanism 6 in the processing groove 13. The first clamping member 31 is provided with a first avoidance groove 312 on the surface close to the workbench 1, and the second clamping member 32 is provided with a second avoidance groove 322 on the surface close to the workbench 1, the first avoidance groove 312 is connected to the processing groove 13, and the second avoidance groove 322 is connected to the processing groove 13.

[0047] Reference Figure 1 and Figure 3The clamping mechanism 4 is used to clamp the fluoroplastic annular workpiece located in the processing area 12, so that when the output end of the second milling mechanism 6 processes the end face of the fluoroplastic annular workpiece below the processing area, the fluoroplastic annular workpiece will not be displaced. As an example, the clamping mechanism 4 includes a clamping member 41 located above the processing area 12, and the clamping member 41 is connected to a clamping drive member 42, and the clamping drive member 42 drives the clamping member 41 to move toward or away from the workbench 1. Specifically, the clamping member 41 includes a first clamping block 411 and a second clamping block 412 located above the processing area 12 and spaced apart along the extension direction of the processing groove 13, and the clamping drive member 42 includes a first clamping drive member 421 and a second clamping drive member 422. The workbench 1 is provided with a first support column 14 and a second support column 15, and the first clamping drive member 421 is installed on the first support column 14, and the second clamping drive member 422 is installed on the second support column 15. The first pressing block 411 is connected to the first pressing drive 421, and the first pressing drive 421 drives the first pressing block 411 to move toward the workbench 1. The second pressing block 412 is connected to the second pressing drive 422, and the second pressing drive 422 drives the second pressing block 412 to move toward the workbench 1. The first pressing drive 421 and the second pressing drive 422 are both cylinders. The piston rod of the first pressing drive 421 is arranged toward the workbench 1, and the piston rod of the second pressing drive 422 is arranged toward the workbench 1. The first pressing block 411 and the second pressing block 412 are used to press the fluoroplastic annular workpiece located in the processing area 12, wherein the spacing space 43 formed by the first pressing block 411 and the second pressing block 412 is used to accommodate the output end of the first milling mechanism 5. When the first pressing block 411 and the second pressing block 412 move toward the workbench 1 to press the fluoroplastic annular workpiece, a partial area of ​​the end surface of the fluoroplastic annular workpiece is squeezed by the first pressing block 411 and the second pressing block 412. The end surface of the fluoroplastic annular workpiece exposed in the spacing space 43 formed by the first pressing block 411 and the second pressing block 412 is the area where the milling groove is required at the output end of the first milling mechanism 5 .

[0048] The first milling mechanism 5 passes through the partition space 43 to mill a groove on one end face of the fluoroplastic annular workpiece above the processing area 12, and the output end of the second milling mechanism 6 passes through the processing groove 13 to mill a groove on the other end face of the fluoroplastic annular workpiece below the processing area 12. Both the first milling mechanism 5 and the second milling mechanism 6 need to mill two grooves on the end face of the fluoroplastic annular workpiece. In order to facilitate the movement of the milling mechanism when milling the grooves, a structure is specifically but not limitedly proposed, in which a first guide rail 16 is arranged above the partition space 43, and a guide rail bracket 18 is arranged on the workbench 1. The first guide rail 16 is arranged on the guide rail bracket 18, and the extension direction of the first guide rail 16 is perpendicular to the extension direction of the processing groove 13, and the first milling mechanism 5 is slidably connected to the first guide rail 16. A second guide rail 17 is arranged below the processing groove 13, and the second guide rail 17 extends along the extension direction of the processing groove 13, and the second milling mechanism 6 is slidably connected to the second guide rail 17. The first guide rail 16 and the second guide rail 17 are both electric guide rails. During milling, the first milling mechanism 5 slides on the first guide rail 16, and the output end of the first milling mechanism 5 can slide into the partition space 43 and slide in the partition space 43 to perform milling on the fluoroplastic annular workpiece above the workbench 1. The second milling mechanism 6 slides on the second guide rail 17 so that the output end of the second milling mechanism 6 can slide in the processing groove 13 to perform milling on the fluoroplastic annular workpiece below the workbench 1.

[0049] Furthermore, the first milling mechanism 5 and the second milling mechanism 6 can both be milling power heads, and the output ends of the first milling mechanism 5 and the second milling mechanism 6 are both arranged toward the workbench 1 .

[0050] Reference Figure 2 The unloading mechanism 7 includes an unloading driving member 71 and an unloading box 72 respectively arranged on two opposite sides of the processing groove 13. The unloading driving member 71 is arranged on the workbench 1, and the unloading box 72 is arranged below the workbench 1. The unloading driving member 71 is connected with an unloading push plate 73. The unloading driving member 71 drives the unloading push plate 73 to move toward or away from the processing area 12. The unloading push plate 73 is used to push the fluoroplastic annular workpiece located in the processing area 12 into the unloading box 72. The unloading driving member 71 is an unloading cylinder. The distance between the top surface of the unloading push plate 73 and the top surface of the workbench 1 is smaller than the distance between the bottom surface of the first pressing block 411 and the top surface of the workbench 1 after the first pressing block 411 is away from the workbench 1, and is also smaller than the distance between the bottom surface of the second pressing block 412 and the top surface of the workbench 1 after the second pressing block 412 is away from the workbench 1. Such arrangement can avoid interference between the first pressing block 411 and the second pressing block 412 when the unloading push plate 73 pushes the fluoroplastic annular workpiece. Furthermore, an unloading track 74 can be overlapped between the workbench 1 and the unloading box 72, and the unloading driving member 71 pushes the fluoroplastic annular workpiece onto the unloading track 74, and the fluoroplastic annular workpiece slides into the unloading box 72 through the unloading track 74.

[0051] The implementation principle of the embodiment of the present application is as follows: the vibrating loading tray 21 conveys the fluoroplastic annular workpiece to the loading area 11 through the loading track 22, the second driving member 34 drives the second clamping member 32 to move toward the processing area 12, and when the second clamping member 32 reaches the processing area 12, the first driving member 33 drives the first clamping member 31 to move toward the processing area 12, and the first clamping member 31 passes through the loading area 11, and can abut against the fluoroplastic annular workpiece located in the loading area 11 and push the fluoroplastic annular workpiece to the processing area 12, when the fluoroplastic annular workpiece is pushed to the processing area 12, the second clamping member 32 can also abut against the fluoroplastic annular workpiece. At this time, the clamping driving member 42 drives the clamping member 41 to move toward the workbench 1, compressing the fluoroplastic annular workpiece located in the processing area 12, the first clamping member 31 moves away from the processing area 12, and the second clamping member 32 also moves away from the processing area 12. After the clamping member 41 clamps the fluoroplastic annular workpiece, the first milling mechanism 5 penetrates into the spacing space 43 to mill a groove on one end face of the fluoroplastic annular workpiece above the processing area 12, and the output end of the second milling mechanism 6 passes through the processing groove 13 to mill a groove on the other end face of the fluoroplastic annular workpiece below the processing area 12. After the milling is completed, the clamping drive member 42 drives the clamping member 41 to move away from the workbench 1, and the unloading mechanism 7 can move the fluoroplastic annular workpiece processed in the processing area 12 out of the processing area 12.
