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.

[0030] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0031] See also Figure 1 and Figure 2 An embodiment of the present application provides a processing device, including a material transport device 1 for transporting a workpiece 6, a clamping device 2 capable of fixing the workpiece 6 at a processing position 120, and a processing device (not shown in the figure) capable of processing the workpiece 6; the material transport device 1 includes a loading component 11, a processing track 12 connected to the loading component 11, and a travel sensor 13, the clamping device 2 and the processing device are both arranged on the side of the processing track 12, and the travel sensor 13 is arranged on the side of the clamping device 2 opposite to the loading component 11.

[0032] See also Figure 1 , Figure 2 and Figure 4 As a specific solution of this embodiment, the clamping device is arranged on both sides of the processing track 12 in the horizontal direction. The processing device includes a processing tool arranged from above the processing position 120 directly facing the processing position 120, and a tool driver for driving the movement and rotation of the processing tool. The tool driver can be arranged on both sides of the processing track 12 in the horizontal direction; the processing device can also include a workbench 3, and the processing track 12 and the travel sensor 13 can be arranged on the workbench 3. The processing tool can be determined according to the specific shape of the workpiece 6 to be processed and the specific processing content. For example, please refer to Figure 4For small-diameter water pipes such as household bathroom equipment, a pipe connector with an internal thread 61 at one end and an external hexagon 62 at the other end is often used. For this type of workpiece 6, after mold forming, the above-mentioned processing equipment with a tapping tool can be used for processing. Each embodiment of the present application takes such a pipe connector with an internal thread 61 at one end and an external hexagon 62 at the other end as an example of the workpiece 6 to be processed, and explains the working method and technical effect of the processing device provided by the present application.

[0033] Specifically, the processing device provided in this embodiment works as follows:

[0034] The material transport device 1 is used to transport the workpiece 6 through the processing position 120, wherein the loading assembly 11 can load the workpiece 6 to the side of the processing track 12 that is opposite to the loading assembly 11, and the workpiece 6 is pushed by another subsequent workpiece 6, or driven by a further power device (such as the pull rod assembly 15 in some embodiments of the present solution) to move to the processing position 120;

[0035] The travel sensor 13 is used to detect whether the workpiece 6 is transferred to the processing position 120. When the workpiece 6 is transferred to the processing position 120, the clamping device 2 firmly clamps the workpiece 6 at the processing position 120 to prevent the workpiece 6 from moving or rotating. Then, the processing device starts processing, and the tool driver drives the tool to process the workpiece 6. For example, the tool driver can drive the tapping tool to process the internal thread 61 on the inner surface of the pipe connector.

[0036] The clamping device 2 and the processing device operate in sequence; when the processing device completes processing of the workpiece 6, the clamping device 2 releases the clamping of the workpiece 6, and the workpiece 6 is pushed by the subsequent workpiece 6, or driven by a further power device (such as the pull rod assembly 15 in some embodiments of the present scheme), and finally falls into a storage device such as a collection box; after the travel sensor 13 detects that the subsequent workpiece 6 is transferred to the position, the clamping device 2 and the processing device operate in sequence again and realize the processing of the workpiece 6.

[0037] The processing device provided in this embodiment has at least the following beneficial technical effects:

[0038] By setting the material transport device 1, the loading component 11 transfers the workpiece 6 to the processing track 12, and the workpiece 6 runs along the processing track 12. When the travel sensor 13 senses that the workpiece 6 is transferred to the right position, the clamping device 2 and the processing device start to operate and process the workpiece 6, such as tapping the inner thread 61 on the inner wall of the workpiece 6, and then the workpiece 6 is further transferred to be unloaded. In this way, the fully automated operation of the processing device is realized, and there is no need to configure a separate operator to load or unload materials, which greatly improves the processing efficiency of the processing device and can prevent the operator from erroneous operation or accidents caused by fatigue after long-term repetitive labor.

[0039] See also Figure 1 , Figure 5 and Figure 6 In one embodiment of the present application, the clamping device 2 includes a first clamp 211 and a second clamp 212 respectively arranged on opposite sides of the processing track 12, a clamp linkage 22 connected to the first clamp 211 and the second clamp 212, and a clamp driver connected to the clamp linkage 22; wherein the clamp driver can drive the clamp linkage 22 to move, and the clamp linkage 22 can drive the first clamp 211 and the second clamp 212 to approach or move away from the processing position 120 at the same time.

[0040] Specifically, the function of the clamping jaw linkage 22 is to fix the posture of the first clamping jaw 211 and the second clamping jaw 212, and to limit the relative movement relationship between the first clamping jaw 211 and the second clamping jaw 212, so that the first clamping jaw 211 and the second clamping jaw 212 are always arranged relative to each other and can approach or move away from each other. The clamping jaw driver further drives the first clamping jaw 211 and the second clamping jaw 212 to approach or move away from the processing position 120 at the same time by driving the clamping jaw linkage 22 to move. The advantage of this is that the first clamping jaw 211 or the second clamping jaw 212 can be prevented from extending above the processing track 12 in a non-clamping state, that is, when the first clamping jaw 211 and the second clamping jaw 212 are in a loose state, the first clamping jaw 211 and the second clamping jaw 212 can move away from the opposite sides of the processing track 12, so that the first clamping jaw 211 and the second clamping jaw 212 will not affect the movement of the workpiece 6 along the processing track 12, thereby preventing the workpiece 6 from touching the first clamping jaw 211 or the second clamping jaw 212 during the transmission along the processing track 12 and causing it to fall off.

[0041] See also Figure 1 , Figure 5 and Figure 6In one embodiment of the present application, the jaw driver includes a first cylinder 23, the jaw linkage 22 includes a jaw track 221, and a connecting rod assembly 222 connected to the first cylinder 23; the first jaw 211 and the second jaw 212 are both movably connected to the jaw track 221, that is, the first jaw 211 and the second jaw 212 can slide along the jaw track 221, the first jaw 211 and the second jaw 212 are both hinged to the connecting rod assembly 222, and the first cylinder 23 is connected to the jaw track 221; the first cylinder 23 can drive the first jaw 211 and the second jaw 212 to approach or move away from the processing position 120 at the same time through the connecting rod assembly 222.

[0042] In this embodiment, the first clamping jaw 211 and the second clamping jaw 212 can slide along the clamping jaw track 221, so that the posture of the first clamping jaw 211 and the second clamping jaw 212 can be fixed, thereby limiting the motion relationship between the first clamping jaw 211 and the second clamping jaw 212. Further, a first cylinder 23 is provided, and a connecting rod assembly 222 is provided for transmission. The first cylinder 23 controls the first clamping jaw 211 and the second clamping jaw 212 to approach or move away from the processing position 120 at the same time through the connecting rod assembly 222, thereby realizing the synchronous control of the first clamping jaw 211 and the second clamping jaw 212 by a single cylinder. Compared with the scheme of using two drivers to control the first clamping jaw 211 and the second clamping jaw 212 respectively, the scheme of using the first cylinder 23 to control the first clamping jaw 211 and the second clamping jaw 212 at the same time has the advantages of simpler and more reliable control circuit and good synchronization of the clamping jaw operation, while reducing the number of cylinders and reducing the cost of the processing device.

[0043] See also Figure 1 , Figure 5 and Figure 6 In one embodiment of the present application, the connecting rod assembly 222 includes a first connecting rod 2221, a second connecting rod 2222, and a third connecting rod 2223; the first connecting rod 2221 includes a first arm 22211, a second arm 22212, and a third arm 22213, one end of the first arm 22211 is connected to one end of the second arm 22212, one end of the third arm 22213 is connected to the connection between the first arm 22211 and the second arm 22212, and this end of the third arm 22213 is connected to the clamping claw The track 221 is hinged, the other end of the third arm 22213 is hinged to the third connecting rod 2223, the end of the first arm 22211 away from the third arm 22213 is hinged to the first cylinder 23, and the end of the second arm 22212 away from the third arm 22213 is hinged to the first clamp 211; one end of the second connecting rod 2222 is hinged to the clamp track 221, the other end of the second connecting rod 2222 is hinged to the third connecting rod 2223, and the second clamp 212 is hinged to the position between the two ends of the second connecting rod 2222.

[0044] As a specific scheme of this embodiment, the first cylinder 23 is also hinged on the clamping jaw track 221; the connecting rod assembly 222 also includes a fourth connecting rod 2224 whose two ends are respectively hinged to the second arm 22212 and the first clamping jaw 211, and a fifth connecting rod 2225 whose two ends are respectively hinged to the second connecting rod 2222 and the second clamping jaw 212. The function of the fourth connecting rod 2224 is to convert the rotation of the first connecting rod 2221 into the translational movement of the first clamping jaw 211 along the clamping jaw track 221, and the function of the fifth connecting rod 2225 is to convert the rotation of the second connecting rod 2222 into the translational movement of the second clamping jaw 212 along the clamping jaw track 221.

[0045] See also Figure 5 and Figure 6 The first connecting rod 2221 is generally in a "Y" shape, and the first cylinder 23 has a piston, and the end of the piston away from the first cylinder 23 is hinged to the first arm 22211. As the piston of the first cylinder 23 extends outward, the first cylinder 23 rotates slightly, and at the same time, the first cylinder 23 controls the rotation of the first connecting rod 2221 around the hinge point between the first connecting rod 2221 and the clamping claw track 221 through the first arm 22211 (from Figure 5 From the perspective of FIG, the first connecting rod 2221 rotates counterclockwise), thereby driving the end of the second arm 22212 away from the above-mentioned hinge point to move toward the processing track 12, and then pushing the first clamping jaw 211 to move toward the processing track 12; at the same time, it can also drive the end of the third arm 22213 away from the above-mentioned hinge point to move toward the first cylinder 23, pulling the third connecting rod 2223 to move toward the first cylinder 23. The other end of the third connecting rod 2223 is hinged to the second connecting rod 2222, one end of the second connecting rod 2222 is hinged to the third connecting rod 2223, and the other end is hinged to the clamping jaw track 221, and the second clamping jaw 212 is hinged to the position between the two ends of the second connecting rod 2222. The rotation of the first connecting rod 2221 can drive the rotation of the second connecting rod 2222 through the third connecting rod 2223 (from Figure 5 From the perspective in FIG, the second connecting rod 2222 rotates counterclockwise), thereby pushing the second clamping jaw 212 to move toward the direction close to the processing track 12.

[0046] In this way, the connecting rod assembly 222 realizes the synchronous control of the first cylinder 23 over the first clamp 211 and the second clamp 212, so that the first clamp 211 and the second clamp 212 can be approached or moved away from the processing track 12 at the same time. There is no need to set up two drivers to control the movement of the first clamp 211 and the second clamp 212 respectively, which simplifies the control circuit of the processing device; the first clamp 211 and the second clamp 212 can operate more synchronously; and the number of cylinders is reduced, further reducing the cost of the processing device.

[0047] See also Figure 1 , Figure 5 and Figure 7 In one embodiment of the present application, the processing device also includes a rotation limit device 4, which includes a rotation limiter 42 arranged opposite to the processing position 120, and a second cylinder 41 connected to the rotation limiter 42; a first through hole 121 is opened at a position of the processing track 12 opposite to the processing position 120, and the second cylinder 41 can drive the rotation limiter 42 to pass through the first through hole 121.

[0048] After the workpiece 6 is in place, the second cylinder 41 can drive the rotation limiter 42 to pass through the first through hole 121 and realize the rotation limit of the workpiece 6. Specifically, the workpiece 6 such as a pipe connector is usually provided with a portion having an outer hexagon 62 to facilitate tightening the connection between the pipe connector and the pipe through a wrench from the outside of the pipe connector. For such pipe connectors, a rotation limiter 42 matching the shape of the outer hexagon 62 is provided to clamp the workpiece 6 during the processing of the processing equipment, thereby preventing the workpiece 6 from rotating during the process of tapping or processing other structures.

[0049] As a specific solution of this embodiment, the second cylinder 41 is connected to the side of the machining track 12 facing away from the machining tool through the connecting platform 43, and the second cylinder 41 is arranged opposite to the first through hole 121; the first through hole 121 can be a waist-shaped hole, a bar-shaped hole or a hexagonal hole, and the length direction of the first through hole 121 extends along the extension direction of the machining track 12. More specifically, a guide groove 122 is formed above the surface of the machining track 12 away from the second cylinder 41, and the workpiece 6 can move along the guide groove 122. The first through hole 121 is arranged on the bottom surface of the guide groove 122, and the length of the first through hole 121 in a direction perpendicular to the extension direction of the machining track 12 is less than or equal to the length of the guide groove 122 in a direction perpendicular to the extension direction of the machining track 12. In this way, it is possible to prevent the workpiece 6 from being stuck in the first through hole 121 due to its own small size without affecting the rotation limiter 42 passing through the first through hole 121.

[0050] Furthermore, the rotation limiter 42 includes a limiter base 421 connected to the second cylinder 41, a first limit platform 422 and a second limit platform 423 arranged on the side of the limiter base 421 facing away from the second cylinder 41, and the first limit platform 422 and the second limit platform 423 are arranged relatively to each other, such as being arranged relatively to each other along the extension direction of the processing track 12, or being arranged relatively to each other in its direction. It is sufficient that the two are located on a plane parallel to the processing track 12, and the workpiece 6 can be clamped between the first limit platform 422 and the second limit platform 423. For example, for a workpiece 6 provided with an external hexagonal corner 62, the side wall of the first limit platform 422 facing the second limit platform 423 can be configured as two surfaces with an angle of 120°, the side wall of the second limit platform 423 facing the first limit platform 422 can be configured as two surfaces with an angle of 120°, and the side wall of the first limit platform 422 facing the second limit platform 423 can be configured as two surfaces with an angle of 120°, and the side wall of the first limit platform 422 facing the second limit platform 423 can form a snap-in groove matching the shape of the external hexagonal corner 62 together with the side wall of the second limit platform 423 facing the first limit platform 422. In this way, the second cylinder 41 can push the first limit platform 422 and the second limit platform 423 to extend out of the first through hole 121 through the limiter base 421, thereby realizing the rotation limit of the workpiece 6 with the external hexagon 62; at the same time, the first through hole 121 can be configured as a long hexagonal hole extending along the length direction of the processing track 12, and the width of the first through hole 121 only needs to be sufficient to allow the first limit platform 422 and the second limit platform 423 to pass through.

[0051] See also Figure 1 and Figure 2 In one embodiment of the present application, the material transport device 1 further includes a stopper assembly 14 capable of blocking the movement of the workpiece 6 along the processing track 12; the stopper assembly 14 includes a stopper drive disposed on the side of the clamping device 2 opposite to the loading assembly 11, and a stopper 142 connected to the stopper drive. The stopper 142 is used to block the subsequent workpiece 6 from continuing to move when the workpiece 6 is being processed, to prevent the first clamping jaw 211 and the second clamping jaw 212 from approaching each other and touching the subsequent workpiece 6 when clamping the previous workpiece 6, and to prevent the subsequent workpiece 6 from falling from the processing track 12.

[0052] As a specific solution of this embodiment, the gear rod driver adopts the fifth cylinder 141. After the stroke sensor 13 senses that the preceding workpiece 6 has been transferred into place, the fifth cylinder 141 can drive the gear rod 142 to extend to prevent the following workpiece 6 from continuing to move. After the preceding workpiece 6 has been processed, the fifth cylinder 141 can drive the gear rod 142 to retract to release the obstruction to the following workpiece 6.

[0053] See also Figure 1 and Figure 3In one embodiment of the present application, the processing device also includes a unloading piece 5 arranged at one end of the processing track 12 away from the loading assembly 11, and a unloading trough is formed above the unloading piece 5; the material transporting equipment 1 also includes a pull rod assembly 15 arranged on the side of the processing track 12, the pull rod assembly 15 includes a pull rod 151, and a pull rod controller 152 connected to the pull rod 151; the pull rod controller 152 can drive the pull rod 151 to pull the workpiece 6 from the side of the gear rod 142 facing the loading assembly 11 to the processing position 120, and / or the pull rod controller 152 can drive the pull rod 151 to pull the workpiece 6 from the processing position 120 to the unloading piece 5.

[0054] As a specific solution of this embodiment, the pull rod controller 152 can drive the pull rod 151 to pull the workpiece 6 from the side of the gear rod 142 facing the loading assembly 11 to the processing position 120, and can drive the pull rod 151 to pull the workpiece 6 from the processing position 120 to the unloading part 5. More specifically, the processing device works as follows: after the travel sensor 13 senses that a workpiece 6 has been loaded into place, the pull rod controller 152 drives the pull rod 151 to pull the workpiece 6 from the side of the gear rod 142 facing the loading component 11 to the processing position 120, and at the same time the gear rod 142 is released to block other workpieces 6 behind the workpiece 6 from continuing to move forward; the workpiece 6 is fixed by the clamping device 2 and the rotation limit device 4, and is processed by the processing equipment; after the workpiece 6 is processed, the pull rod controller 152 drives the pull rod 151 to pull the workpiece 6 from the processing position 120 to the unloading part 5; the gear rod 142 is retracted, and the pull rod controller 152 drives the pull rod 151 to pull the next workpiece 6 from the side of the gear rod 142 facing the loading component 11 to the processing position 120.

[0055] In one embodiment of the present application, the pull rod 151 includes a pull rod body 1511, and a pull rod claw 1512 arranged on the side of the pull rod body 1511 facing the processing track 12; the pull rod controller 152 includes a pull rod track 1521 arranged on the side of the processing track 12, a third cylinder 1522 movably connected to the pull rod track 1521 and connected to the pull rod body 1511, and a fourth cylinder 1523 used to connect the third cylinder 1522 and capable of driving the third cylinder 1522 to slide along the pull rod track 1521; the third cylinder 1522 can drive the pull rod body 1511 to approach or move away from the processing track 12.

[0056] As a specific scheme of this embodiment, the pull rod track 1521 is arranged parallel to the processing track 12, and the third cylinder 1522 can drive the pull rod body 1511 to approach or move away from the processing track 12 in a direction perpendicular to the processing track 12, so that the pull rod claw 1512 can extend into the workpiece 6 along the axial direction of the workpiece 6 to prevent the workpiece 6 from leaving the processing track 12; the fourth cylinder 1523 is used to control the movement of the pull rod 151 along the extension direction of the processing track 12, and the third cylinder 1522 is used to control the movement of the pull rod 151 along the extension direction of the processing track 12. In this way, there is no need to realize the movement of the pull rod 151 along the extension direction of the processing track 12 through the synchronous operation of the third cylinder 1522 and the fourth cylinder 1523. The third cylinder 1522 and the fourth cylinder 1523 can be configured to run in sequence, thereby simplifying the control logic of the processing device.

[0057] As a preferred solution of this embodiment, two pull rod claws 1512 are provided on the side of the pull rod body 1511 facing the processing track 12. When the workpiece 6 is blocked by the stop bar 142, the distance from the workpiece 6 to the processing position 120 is greater than the distance from the processing position 120 to the end of the processing track 12, and when the workpiece 6 is blocked by the stop bar 142, the distance from the workpiece 6 to the processing position 120 is equal to the distance between the two pull rod claws 1512. In this way, the two pull rod claws 1512 can respectively extend into the workpiece 6 in the processing position 120 and the workpiece 6 blocked by the stop bar 142 at the same time. When the pull rod controller 152 drives the pull rod 151 to pull the next workpiece 6 from the side of the stop bar 142 facing the loading assembly 11 to the processing position 120, it can also pull the previous workpiece 6 that has been processed from the processing position 120 to the unloading part 5, further improving the processing efficiency of the processing device on the workpiece 6.

[0058] See also Figure 1 and Figure 8 In one embodiment of the present application, the loading assembly 11 includes a vibrating loader (not shown in the figure), and a screening track 111 connected to the vibrating loader; the end of the screening track 111 away from the vibrating loader is connected to the processing track 12. The screening track 111 can screen the workpieces 6, and block the workpieces 6 that do not enter the screening track 111 in a preset posture from entering the processing track 12, so that each workpiece 6 is loaded to the processing track 12 in a predetermined posture, and the workpiece 6 is pre-corrected before the clamping device 2 and the rotation limit device 4 fix the position and posture of the workpiece 6.

[0059] See also Figure 1 and Figure 8In one embodiment of the present application, the screening track 111 is formed with a screening groove 1110, and the screening track 111 includes a screening part 1111 connected to the vibrating loader, and a connecting part 1112 connected to the processing track 12, and a protrusion 1113 is arranged on the side of the screening part 1111 facing away from the vibrating loader, and the height of the protrusion 1113 gradually increases in the direction approaching the connecting part 1112; or the screening part 1111 is inclined toward the direction facing the vibrating loader, that is, the height of the side of the screening part 1111 facing the vibrating loader is lower than the height of the side of the screening part 1111 facing away from the vibrating loader. The screening part 1111 arranged in this way can also make the workpiece 6 that does not enter the screening track 111 in a preset posture fall back into the vibrating loading tray through the vibration of the vibrating loading tray.

[0060] As a specific solution of this embodiment, the width of the guide groove 122 of the processing track 12 is equal to the size of the side of the workpiece 6 opposite to the processing tool, such as the distance between the two opposite sides of the outer hexagon 62, and the width of the screening groove 1110 is equal to the distance between the two opposite sides of the outer hexagon 62 of the workpiece 6. In this way, if the workpiece 6 enters the screening track 111 with the side provided with the outer hexagon 62 facing downward, the workpiece 6 can be fixed on the screening track 111 by the screening groove 1110 and loaded onto the processing track 12; if the workpiece 6 enters the screening track 111 with the side provided with the outer hexagon 62 facing upward, the workpiece 6 will not be fixed by the screening groove 1110, and will fall back to the vibrating loader under the vibration of the vibrating loader and be loaded again. In this way, the screening track 111 can screen the workpiece 6, and only the workpiece 6 with the side with the external hexagon 62 facing downward can be loaded onto the processing track 12; and since the width of the screening groove 1110 is equal to the distance between the two opposite sides of the external hexagon 62 of the workpiece 6, the screening track 111 can pre-correct the workpiece 6 before the clamping device 2 and the rotation limit device 4 fix the position and posture of the workpiece 6.

[0061] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
