Description

Technical Field

[0001] The present invention belongs to the technical field of cutting processing, and relates to a cutting industrial robot for furniture production. Background Art

[0002] Due to its excellent strength, durability and unique appearance effect, metal materials are widely used in the production of various furniture products. During the furniture production process, some metal materials need to be cut to reach the required size. At this time, in order to improve production efficiency, a cutting industrial robot for metal cutting is often used for operation.

[0003] At present, when a cutting industrial robot cuts metal pipe fittings, in order to improve the cutting efficiency, several metal pipe fittings are usually arranged in a row for cutting. Multiple pipe fittings are arranged side by side, so that some are cut first. The end face of the pipe fitting that is cut first continuously contacts the cutting tool. The continuous contact will increase the friction between the cutting tool and the metal pipe fitting, causing excessive heat generation on the cross section of the pipe fitting, changing the pipe material around the cross section of the pipe fitting, resulting in a decrease in the cross section quality, affecting the quality of subsequent furniture, and accelerating the wear of the cutting tool.

[0004] To solve the above problems, the present invention proposes a cutting industrial robot for furniture production. Summary of the Invention

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] As Figures 1 - 15 shown, the technical solution adopted by the present invention is as follows: A cutting industrial robot for furniture production includes a mounting table 1, a cutting unit, a clamping unit, and a grinding unit.

[0037] There are two mounting tables 1, and the two mounting tables 1 are symmetrically arranged. A support frame is provided between the two mounting tables 1. As Figure 12 shown, the support frame includes a support 4 and a guide plate 15. There are two supports 4, and the guide plate 15 is fixedly connected between the two supports 4. The cutting unit is installed on the support frame. The cutting unit includes a cutting disc 2. A reciprocating lead screw 42 is rotatably installed between the two supports 4, and a second slider 41 is slidably sleeved on the reciprocating lead screw 42. A ball is provided between the second slider 41 and the reciprocating lead screw 42. The second slider 41, the ball, and the reciprocating lead screw 42 form a ball screw pair. The second slider 41 is in limiting sliding connection with the guide plate 15. A first motor 3 for driving the second slider 41 to rotate is installed on the support 4. The second slider 41 is fixedly connected with a second mounting plate 40, and the cutting disc 2 is rotatably installed on the second mounting plate 40. A second motor 14 is installed on the second mounting plate 40, and the output shaft of the second motor 14 is fixedly connected with the cutting disc 2.

[0038] Start the first motor 3 to move the second mounting plate 40 along the guide plate 15, and at the same time drive the cutting disc 2 to rotate through the second motor 14, and the cutting disc 2 cuts the metal part 7 straddling between the two mounting tables 1.

[0039] A plurality of second chutes 46 are opened on each mounting table 1, and the plurality of second chutes 46 are parallel to each other. The length direction of the second chute 46 is perpendicular to the axis direction of the reciprocating lead screw 42. One end of the second chute 46 close to the support frame is defined as the first end, and the other end of the second chute 46 far from the support frame is defined as the second end.

[0040] A clamping unit is slidably arranged in each second chute 46. The clamping unit includes a sliding seat 23, a fixed seat 22, and a clamping block 18.

[0041] The sliding seat 23 is limited and slidably arranged in the second chute 46. The fixed seat 22 and the sliding seat 23 are hinged by a hinge shaft, and a torsion spring is sleeved on the hinge shaft. One end of the torsion spring is fixedly connected to the fixed seat 22, and the other end is connected to the sliding seat 23. Under the action of the torsion spring, the fixed seat 22 is above the sliding seat 23. The hinge shaft is on the side of the fixed seat 22 away from the support frame.

[0042] The metal part 7 to be cut is installed on the corresponding clamping unit. After the metal part 7 is cut off, under the action of its own gravity, the side of the metal part 7 close to the second end of the second chute 46 turns downward, and the fixed seat 22 rotates around the hinge shaft. Until the fixed seat 22 abuts against one side of the sliding seat 23, the metal part 7 is in a vertical state, and the cut of the metal part 7 faces upward.

[0043] The clamping block 18 is limited and slidably arranged on the fixed seat 22. A screw rod 16 is rotatably installed on the fixed seat 22, and the screw rod 16 is threadedly connected to the clamping block 18. A handle is fixedly arranged at the end of the screw rod 16 for facilitating the screwing of the screw rod 16.

[0044] The screw rod 16 is fixedly connected with a first gear 17, a rack 11 matched with the first gear 17 is arranged on the mounting table 1, and the rack 11 is at the second end of the second chute 46. A collecting bucket 5 is arranged at a position corresponding to the rack 11 below the mounting table 1. The sliding seat 23 moves towards the second end of the second chute 46. When the first gear 17 meshes with the rack 11, the screw rod 16 rotates, and the clamping block 18 moves away from the metal part 7, thereby releasing the clamping of the metal part 7, and the metal part 7 falls downward into the collecting bucket 5.

[0045] A plurality of driving components are arranged on the mounting table 1, and the plurality of driving components correspond to the plurality of sliding seats 23 one by one. The driving component drives the corresponding sliding seat 23 to slide in the second chute 46. The driving component includes a third spring 27 and a rotating shaft 13. A first mounting plate 30 is fixedly installed on the mounting table 1, and the rotating shaft 13 is rotatably installed on the first mounting plate 30. The sliding seat 23 is fixedly connected with a first slider 31, the first slider 31 is sleeved on the rotating shaft 13, and an annular groove 38 is formed in the rotating shaft 13 near the first end of the second chute 46. A spiral groove 29 is formed in the rotating shaft 13 along the length direction. The spiral groove 29 is communicated with the annular groove 38. A second relief groove is formed in the sliding seat 23, and the second relief groove penetrates through the first slider 31 and is communicated with the annular groove 38. A second positioning member 36 is slidably arranged in the second relief groove. The second positioning member 36 includes a square section and a cylindrical section. The square section and the cylindrical section are fixedly connected. The square section is slidably arranged in the sliding seat 23, and one end of the cylindrical section cooperating with the rotating shaft 13 is arc-shaped. The cylindrical section slidably passes through the first slider 31 and cooperates with the annular groove 38 and the spiral groove 29. The third spring 27 is sleeved on the rotating shaft 13, and the third spring 27 is fixedly connected between the first slider 31 and the first mounting plate 30.

[0046] A fixing plate 12 is fixedly connected to the lower end surface of the installation table 1, and the fixing plate 12 is located on one side of the second sliding groove 46. A positioning groove 39 is formed in the fixing plate 12 near the first end of the second sliding groove 46, and a positioning rod 32 that cooperates with the positioning groove 39 is elastically slidably arranged on the sliding seat 23. Specifically, a first relief groove is formed in the sliding seat 23, a first positioning member 33 is slidably arranged in the first relief groove, the positioning rod 32 and the first positioning member 33 are slidably connected, and a fourth spring 37 is fixedly connected between the positioning rod 32 and the first positioning member 33.

[0047] When the sliding seat 23 is at the first end of the second sliding groove 46, the positioning rod 32 is inserted into the positioning groove 39, thereby limiting the sliding seat 23. At the same time, the second positioning member 36 is inserted into the annular groove 38. The rotating shaft 13 rotates, the second positioning member 36 slides in the annular groove 38, and the sliding seat 23 remains at the first end of the second sliding groove 46. When the positioning rod 32 disengages from the positioning groove 39 and the second positioning member 36 disengages from the annular groove 38, under the action of the third spring 27, the sliding seat 23 moves towards the second end of the second sliding groove 46. When the sliding seat 23 is at the second end of the second sliding groove 46, one end of the second positioning member 36 extends into the spiral groove 29. As the rotating shaft 13 rotates, the first slider 31 moves along the rotating shaft 13, and the sliding seat 23 moves towards the first end of the second sliding groove 46 until the second positioning member 36 enters the annular groove 38 and the positioning rod 32 is caught in the positioning groove 39.

[0048] A trigger assembly is arranged on the sliding seat 23. When the metal part 7 moves towards the vertical state, under the action of the trigger assembly, the positioning rod 32 disengages from the positioning groove 39 and the second positioning member 36 disengages from the annular groove 38.

[0049] The triggering component includes a push rod 26 and a guide block 25. A first chute 28 is formed in the sliding seat 23, and both the first relief groove and the second relief groove communicate with the first chute 28. The guide block 25 is slidably arranged in the first chute 28. Two guide grooves 34 are symmetrically formed in the guide block 25, and a guide rod 35 is slidably arranged in each guide groove 34. One of the guide rods 35 is fixedly connected to the second positioning member 36, and the other guide rod 35 is fixedly connected to the first positioning member 33. A second spring 24 is arranged in the first chute 28. One end of the second spring 24 is fixedly connected to the guide block 25, and the other end of the second spring 24 is fixedly connected to the inner wall of the first chute 28. The push rod 26 is arranged on one side of the second end of the sliding seat 23 close to the second chute 46. One end of the push rod 26 slidably extends into the first chute 28 and is fixedly connected to the guide block 25. When the fixed seat 22 flips towards one side of the sliding seat 23, the metal part 7 squeezes the push rod 26, causing the guide block 25 to compress the second spring 24 and move into the first chute 28. The two guide rods 35 approach each other. Under the action of the guide rods 35, both the first positioning member 33 and the second positioning member 36 move into the sliding seat 23, thereby causing the positioning rod 32 to disengage from the positioning groove 39 and the second positioning member 36 to disengage from the annular groove 38. Under the action of the third spring 27, the sliding seat 23 moves towards the second end of the second chute 46.

[0050] When the metal part 7 falls off the fixed seat 22, under the action of the second spring 24, the guide block 25 and the push rod 26 move outwards. Under the action of the guide rods 35, the first positioning member 33 and the second positioning member 36 move outwards. The positioning rod 32 abuts against the fixing plate 12 under the action of the fourth spring 37, and the second positioning member 36 is inserted into the spiral groove 29.

[0051] The grinding unit includes a grinding disc 21 and an inclined plane block 19. An L-shaped frame 6 is fixedly installed on the mounting table 1 at a position corresponding to the second chute 46. The grinding disc 21 is elastically movably installed up and down on the L-shaped frame 6. The grinding disc 21 is fixedly connected with a guide post. The upper end of the guide post slidably passes through the L-shaped frame 6 and is fixedly connected with a limit plate. A first spring 20 is fixedly connected between the limit plate and the L-shaped frame 6. The first spring 20 is sleeved on the guide post. The inclined plane block 19 is fixedly connected to one end of the grinding disc 21 close to the support frame. One end of the inclined plane block 19 close to the grinding disc 21 is inclined downwards.

[0052] A third mounting plate 45 is fixedly installed on each mounting table 1. A connecting shaft 8 is rotatably installed on the third mounting plate 45. Sprockets 10 are fixedly connected to both the connecting shaft 8 and the rotating shaft 13. Chains 9 are drivingly arranged between multiple sprockets 10 on the same mounting table 1. One end of the reciprocating lead screw 42 is fixedly connected with a first bevel gear 43. The connecting shaft 8 is fixedly connected with a second bevel gear 44, and the second bevel gear 44 meshes with the first bevel gear 43.

[0053] Working principle: Initially, the sliding seat 23 is at the first end of the second chute 46. Under the action of the fourth spring 37, the positioning rod 32 is inserted into the positioning groove 39, and the second positioning member 36 is inserted into the annular groove 38. One end of the push rod 26 extends outside the sliding seat 23. Under the action of the torsion spring, the fixed seat 22 is on the upper end face of the sliding seat 23. The third spring 27 is in a stretched state.

[0054] Horizontally span the metal part 7 between the two mounting platforms 1, and place the metal part 7 on the corresponding two fixed seats 22. Rotate the screw rod 16 to move the clamping block 18 closer to the metal part 7, thereby clamping and fixing the metal part 7. The metal part 7 is clamped and fixed by the corresponding two clamping units. Install multiple metal parts 7 between the corresponding two clamping units in sequence. Make the midpoint of the metal part 7 and the cutting disc 2 in the same vertical plane, then the metal part 7 can be cut into two equal-length segments.

[0055] Start the first motor 3 and the second motor 14. The second motor 14 drives the cutting disc 2 to rotate. The first motor 3 drives the reciprocating lead screw 42 to rotate, so that the cutting disc 2 moves along the guide plate 15 while rotating. As the cutting disc 2 moves, the cutting disc 2 cuts multiple metal parts 7 in sequence.

[0056] The reciprocating lead screw 42 drives the connecting shaft 8 to rotate through the first bevel gear 43 and the second bevel gear 44. The sprocket 10 on the connecting shaft 8 rotates. Under the action of the chain 9, multiple sprockets 10 all rotate, and multiple rotating shafts 13 rotate. However, since the second positioning member 36 is in the annular groove 38 at this time, the rotating shaft 13 rotates relative to the second positioning member 36, and the second positioning member 36 does not move.

[0057] When the metal part 7 is cut off, the center of gravity of the cut-off metal part 7 falls on the side of the hinge shaft close to the second end of the second chute 46. The cut-off metal part 7 moves towards the vertical state under its own gravity. The cut-off metal part 7 drives the fixed seat 22 to rotate around the hinge shaft until the cut-off metal part 7 is in the vertical state, and the fixed seat 22 abuts against one side of the sliding seat 23. At this time, the cut of the cut-off metal part 7 is vertically upward. When the metal part 7 rotates around the hinge shaft after being cut off, the cut-off metal part 7 is separated from the cutting disc 2, avoiding the continuous contact between the cut-off metal part 7 and the cutting disc 2, which is beneficial to reducing the wear of the cutting disc 2 and improving the quality of the cut at the same time.

[0058] During the process of the cut-off metal part 7 flipping around the hinge shaft, the cut-off metal part 7 presses the push rod 26, causing the push rod 26 to move into the sliding seat 23. The guide block 25 moves in the first chute 28 against the elastic force of the second spring 24. Make the two guide rods 35 approach each other, and the positioning rod 32 and the second positioning member 36 move into the sliding seat 23, so that the positioning rod 32 disengages from the positioning groove 39, and the second positioning member 36 disengages from the annular groove 38.

[0059] After that, under the action of the third spring 27, the sliding seat 23 drives the cut metal part 7 to move towards the second end of the second chute 46. When the metal part 7 moves towards the second end of the second chute 46, the metal part 7 pushes the grinding piece 21 to move upward through the inclined plane block 19. After that, the cut of the metal part 7 moves along the grinding piece 21, and the grinding piece 21 grinds the cut of the metal part 7.

[0060] When the first gear 17 meshes with the rack 11, the first gear 17 rotates to drive the screw rod 16 to rotate, thereby causing the clamping block 18 to move away from the metal part 7, thereby releasing the clamping on the metal part 7. After losing the limit, at this time, the metal part 7 is above the collection bucket 5, and the metal part 7 falls into the collection bucket 5 under its own gravity. The collection bucket 5 collects the cut metal parts 7.

[0061] After the metal part 7 falls, the fixed seat 22 flips upward and resets under the action of the torsion spring, so that the fixed seat 22 is on the upper end surface of the sliding seat 23.

[0062] After the extrusion of the metal part 7 is lost, under the action of the second spring 24, the guide block 25 moves, and the push rod 26 moves out of the sliding seat 23. The two guide rods 35 move away from each other, the first positioning member 33 and the second positioning member 36 move away from each other, the positioning rod 32 abuts against the fixed plate 12, and the second positioning member 36 is inserted into the spiral groove 29. As the rotating shaft 13 rotates, the second positioning member 36 slides in the spiral groove 29, the first slider 31 slides along the rotating shaft 13, the first slider 31 drives the sliding seat 23 to move towards the first end of the second chute 46 close to the second chute 46, and the positioning rod 32 moves along the fixed plate 12. Until the sliding seat 23 returns to the first end of the second chute 46, the second positioning member 36 moves into the annular groove 38, and the positioning rod 32 is inserted into the positioning groove 39. The clamping unit returns to the initial position for the next installation of the metal part 7 to be cut.

[0063] Accordingly, after the metal part 7 is cut, the cut metal part 7 automatically flips, avoiding the continuous contact between the cut metal part 7 and the cutting disc 2. During the flipping process of the metal part 7, the limit on the sliding seat 23 is released through the triggering component, so that the sliding seat 23, the fixed seat 22 and the metal part 7 move towards the second end of the second chute 46. During the movement of the metal part 7, the grinding piece 21 grinds the cut of the metal part 7, improving the quality of the cut and the processing efficiency. When the sliding seat 23 moves to the second end of the second chute 46, the clamping on the metal part 7 is automatically released, and the metal part 7 falls into the collection bucket 5, further improving the processing efficiency. The cutting industrial robot described in the present invention can automatically complete the cutting, grinding, blanking and collection of the metal part 7, improving the cutting quality and contributing to improving the processing efficiency.

[0064] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
