Description

Technical Field

[0001] The invention relates to the technical field of chip conveyors, in particular to a waste chip processing mechanism for a gantry milling machine. Background Art

[0002] Gantry milling machines are mainly used to process large and heavy workpieces. A large amount of metal waste chips will be generated during the processing. Usually, a waste chip processing mechanism, that is, a spiral chip conveyor, will be set on both sides of the gantry milling machine. The metal waste chips generated by the processing will fall into the chip conveyor, and the spiral blades of the spiral chip conveyor will push the waste chips for transportation, thereby realizing the collection and recycling of the waste chips.

[0003] Due to different processing requirements of workpieces, the state of waste chips generated during the processing is also different. In addition, when the milling machine is processing, a large amount of coolant will adhere to the waste chips. Smaller waste chips may enter the gap between the spiral blade and the shell, causing jamming and scratching the shell surface outside the spiral blade. The water in the coolant contacts the scratched part, which may accelerate the damage of the equipment. Therefore, a waste chip handling mechanism for a gantry milling machine is proposed to reduce jamming and wear. Summary of the invention

[0004] In view of the problem in the above or prior art that waste chips may enter the gap between the spiral blade and the shell, causing a jamming phenomenon, the present invention is proposed.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, reference Figures 1 to 6 , which is the first embodiment of the present invention, provides a waste chip processing mechanism for a gantry milling machine, including a driving member 100, which includes a driving motor 101, and a driving shaft 102 connected to the output shaft of the driving motor 101; in this embodiment, the operation of the driving motor 101 can drive the driving shaft 102 to rotate.

[0030] Preferably, the driving shaft 102 includes a screw rod 1021 and a support shaft 1022 connected to the screw rod 1021 , and the end of the support shaft 1022 is rotatably connected to a support disk 1023 ; the support shaft 1022 is rotatably connected to the support disk 1023 via a bearing.

[0031] Furthermore, the containing member 200 includes a collecting groove 201, and a limiting frame 202 slidably arranged in the collecting groove 201, a rotating screw sleeve 203 is rotatably connected in the limiting frame 202, and also includes a rotating disk 204 arranged at the end of the rotating screw sleeve 203; in this embodiment, the collecting groove 201 is usually placed on both sides of the gantry milling machine, and the waste chips generated during the processing of the gantry milling machine will be discharged into the collecting grooves 201 on both sides, the limiting frame 202 can slide along the collecting groove 201, and the rotating screw sleeve 203 is rotatably connected in the limiting frame 202 through a bearing.

[0032] Furthermore, one end of the spiral blade 300 is fixed on the rotating disk 204, and the other end is fixed on the supporting disk 1023; it should be noted that the screw 1021 and the rotating screw sleeve 203 are threadedly connected.

[0033] Specifically, a guide rod 2011 is provided in the collecting tank 201; a guide sleeve 2021 is provided in the limiting frame 202; the guide sleeve 2021 and the guide rod 2011 are slidably connected. In this embodiment, the movement of the limiting frame 202 can be limited by the guide sleeve 2021 cooperating with the guide rod 2011.

[0034] Furthermore, a protective sleeve 2033 is provided at one end of the rotating screw sleeve 203 . In the present embodiment, the protective sleeve 2033 is sleeved on the outside of the supporting shaft 1022 to prevent waste chips from entering the rotating screw sleeve 203 .

[0035] When in use, the waste chips generated by the gantry milling machine during operation fall into the collecting tank 201, and the driving motor 101 is driven to rotate the driving shaft 102. Since the rotating screw sleeve 203 and the screw rod 1021 are in a threaded connection state, one end of the spiral blade 300 is fixedly connected to the rotating disk 204, and the supporting disk 1023 and the supporting shaft 1022 are in a rotationally connected state. Therefore, when the spiral blade 300 is rotated, it is necessary to apply a rotating force through the rotating disk 204. The rotating screw sleeve 203 and the screw rod 1021 are threadedly connected. When the spiral blade 300 is blocked and the rotation resistance increases, the rotating screw sleeve 203 can be used to rotate the screw 1021. The rotation method can achieve a certain buffering effect. When jamming occurs, the rotating screw sleeve 203 rotates outside the screw rod 1021, and the limiting frame 202 slides in the collecting groove 201. The distance between the supporting disk 1023 and the rotating disk 204 increases, so the spiral blade 300 will also extend. Due to the spiral setting of the spiral blade 300, when the spiral blade 300 extends, the distance between its outer surface and the collecting groove 201 will increase, so that the waste chips stuck in the gap between the spiral blade 300 and the collecting groove 201 can slide out easily. At the same time, after the spiral blade 300 extends, the pitch will also change, which is more conducive to the sliding out of the jammed waste chips and facilitates getting rid of the jam.

[0036] It should be noted that when there is no jamming phenomenon, when the spiral blade 300 rotates, it is mostly subjected to thrust along the axial direction of the drive shaft 102, and the spiral blade 300 pushes the waste chips to be discharged. Therefore, during normal operation, no rotation will occur between the rotating screw sleeve 203 and the screw 1021, which can ensure normal operation. Only when waste chips are blocked around the spiral blade 300 and the rotation resistance of the spiral blade 300 increases to a large value, the rotation of the drive shaft 102 at this time will cause the rotating screw sleeve 203 and the screw 1021 to rotate. In addition, Due to the existence of the spiral blade 300, the spiral blade 300 itself will generate a certain thrust, which makes the support disk 1023 and the rotating disk 204 tend to move away from each other, but this force is also a force acting in the axial direction of the drive shaft 102, so it will not promote the rotation between the rotating screw sleeve 203 and the screw 1021. Moreover, it can also increase the friction between the rotating screw sleeve 203 and the screw 1021 and enhance the anti-slip effect to ensure that during normal operation, no rotation will occur between the rotating screw sleeve 203 and the screw 1021.

[0037] The spiral blade 300 is further explained. The spiral setting of the spiral blade 300 is such that when the length of the spiral blade 300 is compressed, its outer diameter will increase and the pitch will decrease, and when the spiral blade 300 is extended, the outer diameter will decrease and the pitch will increase. The two ends of the spiral blade 300 are fixed by the support disk 1023 and the rotating disk 204. The support shaft 1022 can provide auxiliary support and limit the spiral blade 300. The diameter of the support shaft 1022 can be set according to the inner diameter of the spiral blade 300, which can play a role in limiting the spiral blade 300.

[0038] Example 2, reference Figure 1 to Figure 6 , which is the second embodiment of the present invention. Different from the previous embodiment, a containing frame 2022 is provided on the limiting frame 202; it also includes a locking piece 400 slidably arranged in the containing frame 2022; a cylindrical groove 2031 is provided in the rotating screw sleeve 203, and a plug-in groove 2032 is provided on the outer wall of the rotating screw sleeve 203. In this embodiment, the setting of the cylindrical groove 2031 can reduce the area of ​​the threaded connection between the rotating screw sleeve 203 and the screw rod 1021, and is conducive to the movement of the rotating screw sleeve 203 outside the driving shaft 102. The outer wall of the rotating screw sleeve 203 is provided with a plurality of plug-in grooves 2032 at equal intervals and circumferentially distributed, and the locking piece 400 is used to be inserted into the plug-in groove 2032.

[0039] Specifically, a support block 2023 is provided in the accommodating frame 2022; the locking member 400 includes an inserting plate 401 slidably arranged in the accommodating frame 2022, and a sliding groove 402 arranged on the inserting plate 401, and also includes a spring 403 arranged in the sliding groove 402. In this embodiment, the support block 2023 and the sliding groove 402 are slidably connected, the support block 2023 can limit the inserting plate 401, and the setting of the spring 403 can make the inserting plate 401 have a movement tendency to slide out of the accommodating frame 2022.

[0040] Furthermore, a pressing block 404 is provided on the plug board 401 . In the present embodiment, the arrangement of the pressing block 404 facilitates pressing the plug board 401 .

[0041] The rest of the structure is the same as that of Example 1.

[0042] Since the waste chips generated when the gantry milling machine is working are in different states and sizes, the spring 403 is compressed by pressing the extrusion block 404, and the plug plate 401 is inserted into the plug-in slot 2032. At this time, the rotating screw sleeve 203 can be fixed so that it cannot rotate. By controlling the forward or reverse rotation of the drive motor 101, the screw 1021 can be controlled to rotate, so that the rotating disk 204 and the limit frame 202 can slide, so that the spiral blade 300 is compressed or extended, which is convenient for adjusting the gap between the spiral blade 300 and the collecting tank 201, and also for adjusting the pitch of the spiral blade 300. At the same time, the thrust of the spiral blade 300 on the rotating disk 204 and the supporting disk 1023 can be adjusted, and the friction between the rotating screw sleeve 203 and the screw 1021 can be adjusted to change the rotational force required for the spiral blade 300 to rotate and change its anti-jamming ability.

[0043] Example 3, reference Figure 1 to Figure 7 , which is the third embodiment of the present invention. Different from the previous embodiment, it also includes an extrusion member 500 rotatably arranged on the accommodating frame 2022; the extrusion member 500 includes a connecting arm 501 rotatably arranged on the accommodating frame 2022, and a resistance block 502 arranged on the connecting arm 501; the resistance block 502 is provided with a fitting surface 5021 and a resistance surface 5022.

[0044] Reference Figure 4 In this state, the extrusion piece 500 is in a horizontal state, and the fitting surface 5021 fits against the top of the plug board 401. At this time, the plug board 401 is not inserted into the plug slot 2032. When the contact block 502 is rotated by the connecting arm 501, the rotation of the fitting surface 5021 will cause the plug board 401 to slide toward the plug slot 2032 until the contact surface 5022 contacts the top of the plug board 401 and the plug board 401 is completely inserted into the plug slot 2032. Therefore, the operator can adjust the connection position of the rotating screw sleeve 203 and the screw rod 1021 by pushing the extrusion piece 500 and cooperating with the operation of the drive motor 101, thereby adjusting the state of the spiral blade 300.

[0045] Specifically, a push plate 600 is provided on the inner wall of the collecting tank 201 ; a hook 503 is provided at the end of the connecting arm 501 ; in this embodiment, the end of the push plate 600 is inclined, and the hook 503 is inclinedly arranged at one end of the connecting arm 501 .

[0046] Furthermore, the driving shaft 102 further includes a connecting shaft 1024 disposed at the end of the screw rod 1021 , and the connecting shaft 1024 is connected to the output shaft of the driving motor 101 .

[0047] When the spiral blade 300 is stuck, the rotating screw sleeve 203 rotates outside the screw rod 1021, and the hook 503 will approach the push plate 600 until the hook 503 contacts the push plate 600. If it is still in or appears to be stuck, the movement of the rotating screw sleeve 203 will cause the hook 503 to be contacted by the push plate 600, thereby pushing the connecting arm 501 to rotate, and the plug plate 401 is inserted into the plug groove 2032 through the rotation of the fitting surface 5021. After the plug plate 401 is inserted into the plug groove 2032, the rotating screw sleeve 203 will be restricted from rotating, that is, the spiral blade 300 will definitely stop rotating, and the rotating screw sleeve 203 moves to the connecting shaft 1024 and loses the threaded connection. Therefore, even if the drive shaft 102 continues to rotate, the spiral blade 300 will not continue to rotate, so the spiral blade 300 and the collecting tank 201 can be protected.

[0048] Preferably, a hanging rod 2012 is provided on the top of the collecting tank 201 ; and an inclined surface 5023 is provided on the abutment block 502 .

[0049] By rotating the connecting arm 501 and cooperating with the operation of the driving motor 101, the rotating screw sleeve 203 is brought close to the hanging rod 2012. After approaching, the connecting arm 501 is further rotated so that the hook 503 is against the hanging rod 2012. At this time, the rotating screw sleeve 203 is controlled to be away from the hanging rod 2012 by the operation of the driving motor 101, and the hook 503 is pushed to be against the hanging rod 2012. Figure 3 When the inclined surface 5023 is in contact with the top of the plug plate 401, the plug plate 401 is in a state of being pulled out from the plug slot 2032. In this state, even if the spiral blade 300 encounters a large resistance during operation, since the hook 503 is hung on the hanging rod 2012, the limit frame 202 cannot slide in the direction of the push plate 600, that is, no displacement can occur between the rotating screw sleeve 203 and the screw rod 1021. In this state, the spiral blade 300 can be guaranteed to rotate continuously.

[0050] The rest of the structure is the same as that of Example 2.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
