Technical Field

[0001] The present invention relates to the technical field of numerically controlled lathes, in particular to a numerically controlled lathe and a processing method for processing a multi-station valve body. Background Art

[0002] CNC machine tools automatically process parts according to pre-programmed procedures. The part's machining process route, process parameters, tool motion trajectory, displacement, cutting parameters, and auxiliary functions are compiled into a machining program sheet according to the instruction code and program format specified by the CNC machine tool. The contents of this program sheet are then recorded on a control medium and input into the CNC device of the CNC machine tool, thereby directing the machine tool to process the part. Existing CNC machine tools require that single or multiple valve bodies be fixedly mounted on single or multiple chucks before machining a valve body. The valve body is then machined using a controlled tool. After machining is completed, the machined valve bodies are removed from the chuck one by one and a new set of valve bodies is installed on the chuck. The process of installing and removing the valve body is too complicated, making it difficult to achieve continuous machining of the valve body. Furthermore, the machined valve body must be removed from the chuck and a new valve body installed on the chuck during machining. Summary of the Invention

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0036] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a CNC lathe and a processing method for multi-station valve body processing.

[0037] Example 1:

[0038] See also Figure 1-Figure 3 , a CNC lathe, comprising a CNC machine tool 1, characterized in that: a loading device 2, a transport device 3 and a processing device 4 are provided in the CNC machine tool 1;

[0039] The loading device 2 includes a loading tray 21, a plurality of clamping members 22 provided on the loading tray 21, and a driving member 5 for controlling the operation of the loading tray 21 and the clamping members 22;

[0040] The transport device 3 is provided at the bottom of the loading tray 21 and includes a transport belt 31 , and power is transmitted between the transport belt 31 and the driving member 5 ;

[0041] Power transmission between the processing device 4 and the transport device 3 so that the processing device 4 and the transport device 3 move synchronously;

[0042] The driving member 5 runs in the forward direction, driving the loading plate 21 to rotate, driving the processed workpiece to separate from one side of the processing device 4, and driving the workpiece fixed in the clamping member 22 to separate from the transport device 3, and at the same time driving the transport device 3 to run so that the new workpiece on the transport device 3 moves to the position of the previous workpiece. Then the driving member 5 runs in the reverse direction, controlling the clamping member 22 holding the processed workpiece to open, and at the same time controlling the clamping member 22 directly below the loading plate 21 to clamp the new workpiece on the transport device 3.

[0043] Specifically, the processing device 4 moves toward the loading plate 21, and drives the transport device 3 to move synchronously and away from the bottom of the loading plate 21. The processing device 4 processes the valve body on the clamping member 22 on the top of the loading plate 21. After the processing is completed, the processing device 4 moves away from the loading plate 21, and drives the transport device 3 to move synchronously and is located at the bottom of the loading plate 21. The driving member 5 runs in the forward direction, drives the loading plate 21 to rotate, thereby driving the clamping member 22 on the top of the loading plate 21 to rotate downward, and drives the valve body on the clamping member 22 that has been processed to separate from the front of the processing device 4, and at the same time The clamping member 22 at the bottom of the loading plate 21 rotates upward, and drives the valve body fixed on the clamping member 22 to separate from the transport device 3. The driving member 5 moves forward, and drives the transport device 3 to move, and transports the new valve body to the bottom of the loading plate 21. Then the driving member 5 moves in the reverse direction, and drives the clamping member 22 above the loading plate 21 to loosen the valve body that has been processed, so that the valve body that has been processed is separated from the clamping member 22. At the same time, it drives the clamping member 22 at the bottom of the loading plate 21 to clamp the new valve body on the transport device 3, so that the processing device 4 can continue to process the valve body.

[0044] After the valve body is processed, the driving member 5 runs forward, driving the processed valve body to rotate downward, and at the same time the valve body in the later position rotates upward, and the subsequent driving member 5 runs in the reverse direction, so that the processed valve body is separated from the clamping member 22, and at the same time the transportation device 3 runs to transport the new valve body to the bottom of the clamping member 22, and clamp the new valve body by the clamping member 22, so that the operation of the driving member 5 can realize continuous processing of the valve body, and during the processing, the processed valve body is removed from the chuck, and the new valve body is installed on the chuck. This solves the problem that after the CNC machine tool 1 completes the processing of the valve body, the processed valve bodies are taken out from the chuck one by one, and a new round of valve bodies are installed on the chuck, and the process of installing and disassembling the valve body is too complicated.

[0045] Example 2:

[0046] The difference from the above embodiment 1 is that, see Figure 2-Figure 9 For the above-mentioned loading device 2, the clamping member 22 includes two clamping jaws 221. A plurality of slide grooves 222 are provided on the loading plate 21. The two clamping jaws 221 are respectively slidably arranged on both sides of the inner cavity of the slide groove 222. A bidirectional screw 223 is rotatably connected to the slide groove 222 through a bearing. The two clamping jaws 221 are arranged on both sides of the outer periphery of the bidirectional screw 223 and are threadedly connected to the bidirectional screw 223.

[0047] Specifically, when the driving member 5 runs in the forward direction, it drives the loading plate 21 to rotate, so that the processed valve body and the clamping member 22 rotate downward, and at the same time, the clamping member 22 at the bottom of the loading plate 21 that has clamped the valve body rotates upward, and the new clamping member 22 is located directly above the new valve body on the conveyor belt 31. The driving member 5 runs in the reverse direction, driving the bidirectional screw 223 to rotate. Through the arrangement of the two clamping jaws 221 located on both sides of the outer periphery of the bidirectional thread, and the arrangement of the bidirectional screw 223 being threadedly connected to the two clamping jaws 221, the two clamping jaws 221 in the clamping member 22 above the loading plate 21 are driven to move backwards, so that the processed valve body is separated from the clamping member 22, and at the same time, the two clamping jaws 221 in the clamping member 22 at the bottom of the loading plate 21 are driven to move toward each other, thereby clamping the new valve body on the conveyor 3.

[0048] Example 3:

[0049] The difference from the above embodiment 2 is that, see Figure 2-Figure 9 , as for the above-mentioned driving member 5, the driving member 5 includes a tooth plate 51, a first tooth groove 52 is opened in the middle of the outer periphery of the bidirectional screw 223, a hole groove 53 is opened on one side of the loading plate 21, the tooth plate 51 is slidably arranged in the hole groove 53, the tooth plate 51 is threadedly connected to the bidirectional screw 223 through the first tooth groove 52, and a bracket 54 is fixedly connected to the side of the loading plate 21 away from the clamping jaw 221. The bracket 54 is rotatably connected to the first screw 55 through a bearing. A screw groove is opened at one end of the tooth plate 51, and the first screw 55 is threadedly connected to the tooth plate 51 through the screw groove. One end of the first screw 55 is fixedly connected to the first gear 56;

[0050] The driving member 5 also includes a servo motor 57. One side of the loading disk 21 is fixedly connected to a rotating rod 58. A carrying plate 59 is fixedly connected inside the CNC machine tool 1. The rotating rod 58 is rotatably mounted on the carrying plate 59 via a bearing. The side of the carrying plate 59 away from the loading disk 21 is fixedly connected to a base. The servo motor 57 is fixedly mounted on the base. One side of the carrying plate 59 is rotatably connected to a connecting rod 510 via a bearing. The output end of the servo motor 57 is fixedly connected to one end of the connecting rod 510. The rotating rod 58 is rotatably connected to one end of the connecting rod 510 via a one-way bearing.

[0051] The driving member 5 also includes a second gear 511. Three transmission gears 512 are rotatably connected to the side of the supporting plate 59 near the servo motor 57 through bearings. An external gear 513 is fixedly connected to the outer periphery of the connecting rod 510. A double-sided toothed belt 514 is sleeved around the outer periphery of the external gear 513 and two of the transmission gears 512. The double-sided toothed belt 514 is meshed with the three transmission gears 512 and the external gear 513. Two movable rods 515 are rotatably connected to the other side of the supporting plate 59 through bearings. One end of the two movable rods 515 is rotatably connected to one end of two of the transmission gears 512 through a one-way bearing. The second gear 511 is fixedly mounted on the other end of the movable rod 515. The second gear 511 is meshed with the first gear 56.

[0052] Specifically, the servo motor 57 runs in the forward direction, driving the connecting rod 510 to rotate in the forward direction, thereby driving the rotating rod 58 to rotate, and at the same time, through the double-sided toothed belt 514, driving the three transmission gears to rotate. Since the movable rod 515 is rotationally connected to the transmission gear 512 through a one-way bearing, when the transmission gear 512 rotates, it cannot drive the movable rod 515 to rotate. At this time, the connecting rod 510 rotates in the forward direction, driving the clamping member 22 with the processed valve body to rotate downward, and driving the adjacent clamping member 22 with the unprocessed valve body to be located at the top of the loading tray 21. At the same time, it drives the clamping member 22 with the unprocessed valve body at the bottom of one side of the loading tray 21 to rotate upward, and drives the clamping member 22 without the valve body to be located at the bottom of the loading tray 21 and directly above the conveyor belt 31, and makes the two first gears 56 and the two second gears 511 in a meshing state;

[0053] Then the servo motor 57 runs in the reverse direction, driving the connecting rod 510 to rotate in the reverse direction. Since the connecting rod 510 is rotatably connected to the rotating rod 58 through a one-way bearing, the rotating rod 58 stops rotating. At the same time, the three transmission gears 512 are driven to rotate through the meshing connection between the double-sided toothed belt 514, the three transmission gears 512, and the outer gear 513. One of the movable rods 515 is connected to the transmission gear 512 above the side of the supporting plate 59 and located on the inner side of the double-sided toothed belt 514, and the other movable plate is connected to the transmission gear 512 below the side of the supporting plate 59 and located on the outer side of the double-sided toothed belt 514. Therefore, when the outer gear 513 rotates, the two transmission gears 512 are driven to rotate in the opposite direction, thereby making the two second gears 511 rotate in the opposite direction, so that the two clamping claws 221 of the clamping member 22 above the supporting plate 59 move in opposite directions, and the two clamping claws 221 of the clamping member 22 below the supporting plate 59 move in opposite directions.

[0054] When the first gear 56 is meshed with the second gear 511, the second gear 511 rotates, driving the first gear 56 to rotate, thereby driving the first screw 55 to rotate, and through the threaded connection between the first screw 55 and the tooth plate 51, driving the tooth plate 51 to move forward, and through the meshing connection between the tooth plate 51 and the first tooth groove 52, driving the bidirectional screw 223 to rotate, thereby driving the two clamping jaws 221 to make relative motion.

[0055] Example 4:

[0056] The difference from the above embodiment 3 is that, see Figure 10-12 The transport device 3 further includes a transport roller 32. Two fixed plates 33 are provided in the CNC machine tool 1. The two transport rollers 32 are respectively arranged between the two fixed plates 33 and are rotatably connected to the two fixed plates 33. The transport belt 31 is sleeved on the transport rollers 32. A plurality of partitions 34 are fixedly installed on the transport belt 31. A cross groove 35 is opened at the axis of one of the transport rollers 32.

[0057] The driving member 5 also includes a cross rod 516. A round block 517 is rotatably connected to the side of the carrier plate 59 near the loading plate 21 via a bearing. A second tooth groove 518 is formed on the outer periphery of the round block 517 and the rotating rod 58. A single-sided tooth belt 519 is sleeved on the outer periphery of the round block 517 and the rotating rod 58. The single-sided tooth belt 519 is meshed with the round block 517 and the rotating rod 58 through the tooth groove. The cross rod 516 is fixedly mounted on one end of the round block 517 and sleeved in the cross groove 35.

[0058] Specifically, when the driving member 5 runs in the forward direction, it drives the rotating rod 58 to rotate. The second tooth groove 518 is provided on the outer periphery of the rotating rod 58 and the round block 517, and the single-sided toothed belt 519 is engaged with the rotating rod 58 and the round block 517 through the second tooth groove 518, thereby driving the round block 517 to rotate. Through the matching setting between the cross rod 516 at one end of the round block 517 and the cross groove 35 at the axis of the transport roller 32, when the round block 517 rotates and drives the cross rod 516 to rotate, the transport roller 32 is driven to rotate, thereby driving the transport belt 31 to rotate, thereby driving the new valve body to move to the bottom of the clamping member 22.

[0059] Embodiment 5:

[0060] The difference from the above-mentioned fourth embodiment is that, see Figure 10For the above-mentioned processing device 4, the processing device 4 includes a welding gun 41, one side of the welding gun 41 is fixedly connected to a first cylinder 42, the output end of the first cylinder 42 is fixedly connected to the tail end of the welding gun 41, the bottom of the first cylinder 42 is fixedly connected to a slide 43, the slide 43 is slidably arranged at the bottom of the inner cavity of the CNC machine tool 1, a second cylinder 44 is provided on one side of the bottom of the slide 43, the output end of the second cylinder 44 is fixedly connected to the slide 43, the other side of the slide 43 is fixedly connected to a load-bearing seat 45, the top fixed rod of the load-bearing seat 45 is connected to two baffles 46, and the transport device 3 is arranged on the top of the load-bearing seat 45 and between the two baffles 46;

[0061] A discharge hole 47 is provided at the bottom of the inner cavity of the CNC machine tool 1 , and a material port 48 is provided outside the CNC machine tool 1 , and the discharge hole 47 is connected to the material port 48 ;

[0062] Specifically, the second cylinder 44 drives the slide 43 to move forward, thereby driving the welding gun 41 to move toward the clamping member 22, and the valve body in the clamping member 22 is processed by the welding gun 41. At the same time, the transportation device 3 is arranged between the two baffles 46 on the top of the load-bearing seat 45, and the sliding connection between the cross rod 516 and the cross groove 35, so that the slide 43 drives the transportation device 3 to move in the opposite direction of the loading tray 21 during the forward movement, to prevent welding slag and other debris from falling onto the conveyor belt 31 and the unprocessed valve body during the processing of the valve body by the welding gun 41. When the welding gun 41 completes the processing of the valve body, the welding gun 41 moves away from the loading tray 21, and at the same time drives the transportation device 3 to move to the bottom of the loading tray 21, and picks up and clamps the new valve body on the transportation device 3 through the setting of the driving member 5. At this time, the valve body that has been processed and separated from the clamping member 22 falls downward and falls to the material port 48 through the discharge hole 47 for easy picking.

[0063] Example 6:

[0064] See Figures 1-12 This embodiment discloses a processing method for multi-station valve body processing, and the specific steps are:

[0065] The processing device 4 moves toward the loading plate 21 and drives the transport device 3 to move synchronously and away from the bottom of the loading plate 21. The processing device 4 processes the valve body on the clamping member 22 at the top of the loading plate 21. After the processing is completed, the processing device 4 moves away from the loading plate 21 and drives the transport device 3 to move synchronously and is located at the bottom of the loading plate 21. The driving member 5 runs forward, driving the loading plate 21 to rotate, thereby driving the clamping member 22 at the top of the loading plate 21 to rotate downward, and driving the valve body on the clamping member 22 that has been processed to separate from the front of the processing device 4, and at the same time driving the loading plate 21 to rotate downward. The clamping member 22 at the bottom of the loading plate 21 rotates upward and drives the valve body fixed on the clamping member 22 to separate from the transport device 3. While the driving member 5 runs forward, it drives the transport device 3 to run and transports the new valve body to the bottom of the loading plate 21. Then the driving member 5 runs in the reverse direction, driving the clamping member 22 above the loading plate 21 to loosen the valve body that has been processed, so that the valve body after processing is separated from the clamping member 22. At the same time, it drives the clamping member 22 at the bottom of the loading plate 21 to clamp the new valve body on the transport device 3, so that the processing device 4 can continuously process the valve body.

[0066] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
