Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to a robot for turning shaft parts. Background Technology

[0002] In existing shaft parts processing equipment, the insufficient reliability of robot clamping is a prominent technical challenge.

[0003] To prevent oxidation, the surface of round shafts is usually coated with a protective oil. However, traditional clamping devices are prone to slippage when clamping such oily workpieces because the friction on the contact surface is significantly reduced. Especially during drilling or cutting operations, the round shaft may rotate unexpectedly under force, leading to machining position deviation, hole position deviation, or even machining failure, which seriously affects product quality and consistency. In addition, the existing grooving process is cumbersome and inefficient. It usually requires a robotic arm to first transfer the round shaft and re-clamp it to an independent external rotary clamping device, which then drives the round shaft to rotate so that it contacts a fixed cutting tool to complete the curved surface grooving. This process involves multiple handling, positioning, and clamping, which not only prolongs the production cycle and increases equipment complexity, but also easily leads to the accumulation of errors due to repeated positioning, reducing machining accuracy. Summary of the Invention

[0014] Preferably, the first Y-tube, the first conduit, the second Y-tube, the second conduit, and the third conduit are all made of hydraulically flexible rubber tubing, and the specific arrangement is designed according to actual conditions to avoid affecting the rotation or movement of the device.

[0015] The beneficial effects of this invention are as follows: 1. When drilling is required at both ends of a round shaft, this invention reverses the activation of the first single-chamber piston cylinder and forwards the activation of the first one-way valve, causing the telescopic end of the second telescopic device to retract and pull the second clamping plate to clamp the round shaft. Then, forwards the activation of the third single-chamber piston cylinder, causing the rotating shaft of the rotating mechanism to contact the round shaft and drive the clamped round shaft to rotate. Afterwards, the second water pump is activated and the second one-way valve is reversed, allowing the cleaning fluid drawn by the second water pump to flow through the second one-way valve and the second conduit into the middle of the first telescopic device. The cleaning fluid flowing into the middle of the first telescopic device is then sprayed onto the rotating shaft. The moving curved surface of the round shaft cleans the grease on the surface of the round shaft. Then, the first single-chamber piston cylinder and the first one-way valve are activated in reverse, causing the extension end of the first telescopic device to retract. At this time, the first telescopic device drives the first clamping plate to clamp the cleaned curved surface of the round shaft. Finally, through the mechanical arm, one end or curved surface of the round shaft comes into contact with the externally rotating drill bit to realize the drilling of the round shaft. This solves the technical problem that the existing machine clamping device is prone to slippage when clamping a round shaft with a protective oil covering its surface, which causes the round shaft to rotate during the drilling process and causes processing failure.

[0016] 2. When it is necessary to groove the curved surface of the round shaft, the present invention reverses the operation of the first single-chamber piston cylinder and the first one-way valve to clamp the round shaft using the first clamping mechanism. Then, the second water pump is started and the second one-way valve is activated in the forward direction, allowing cleaning fluid to flow into the middle of the second telescopic devices on both sides to clean the curved surfaces of the round shaft. Next, the first single-chamber piston cylinder is reversed and the first one-way valve is activated in the forward direction, causing the second clamping mechanism to clamp the cleaned round shaft. Then, the first single-chamber piston cylinder is activated in the forward direction and the first one-way valve is activated in the reverse direction, stopping the first clamping mechanism from clamping the round shaft. Finally, the third single-chamber piston cylinder is activated in the forward direction. The cylinder causes the rotating mechanism's shaft to contact the round shaft, driving the clamped round shaft to rotate. Then, the robotic arm is activated, causing the rotating round shaft's curved surface to contact an externally fixed cutting tool. The cutting tool slots the round shaft's curved surface. This achieves the simultaneous clamping of the round shaft by the second clamping mechanism and the rotating mechanism, driving the round shaft to rotate and contact the externally fixed cutting tool, thus slotting the round shaft's curved surface. This solves the problem of existing cutting devices, which require the robotic arm to first install the round shaft onto an external clamping device, and then drive the round shaft to rotate and contact the fixed tool for slotting, resulting in increased processes and reduced efficiency.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figures 1 to 6 As shown, a robot for turning shaft parts includes a mounting base 1, a mounting plate 101 fixedly mounted on the upper surface of the mounting base 1, and a robotic arm 2 fixedly mounted on the right side of the upper surface of the mounting base 1. It also includes: The first clamping mechanism 3 includes a first guide seat 301, which is fixedly installed on the front side of the top of the robotic arm 2. A first mounting groove is provided on the front side of the first guide seat 301. First fixing plates 302 are fixedly sleeved on the upper and lower sides of the first mounting groove. A first lead screw 303 is movably sleeved on the left side of the two first fixing plates 302. A first telescopic device 304 is fixedly installed in the middle of the first mounting groove. The first telescopic device 304 is movably sleeved with the first lead screw 303. First clamping plates 305 are symmetrically slidably sleeved on the upper and lower sides of the first mounting groove. The two telescopic ends on the right side of the first telescopic device 304 are fixedly connected to their adjacent first clamping plates 305 respectively. The first clamping plates 305 are threadedly connected to the first lead screw 303. In this device, the upper and lower threads of the first telescopic device 304 have opposite directions of rotation, and the pitch of the upper and lower threads of the first telescopic device 304 is the same. This allows the upper and lower sleeve rods 3043 to drive the upper and lower first clamping plates 305 to move closer together when the hydraulic oil in the inner cavity of the sleeve hole 3042 flows back to the inner cavity of the first hydraulic mechanism 7. The upper and lower first clamping plates 305 simultaneously push the first lead screw 303 to rotate, thereby ensuring that the upper and lower first clamping plates 305 move closer together synchronously and at equal distances. This avoids the problem of uneven extension and retraction length of the two upper and lower sleeve rods 3043, which could cause the upper and lower positions of the round shaft held by the second clamping plate 505 to shift. Two connecting blocks 4 are symmetrically and fixedly installed in the middle of the left and right sides of the first guide seat 301; Two second clamping mechanisms 5 are respectively located on the side of the two connecting blocks 4 away from the first clamping mechanism 3; Rotation mechanism 6 is located in front of the two second clamping mechanisms 5; The first hydraulic mechanism 7 is disposed between the first clamping mechanism 3, the two second clamping mechanisms 5 and the surface of the mounting base 1. A cleaning mechanism 8 is provided between the first clamping mechanism 3, the two second clamping mechanisms 5 and the mounting base 1. A second hydraulic mechanism 9 is provided between the rotating mechanism 6 and the upper surface of the mounting plate 101.

[0022] Please see Figure 1 , Figure 2 and Figure 6 As shown, the second clamping mechanism 5 includes a second guide seat 501, which is fixedly installed on the side of the connecting block 4 away from the first clamping mechanism 3. A second mounting groove is provided on the front side of the second guide seat 501. Second fixing plates 502 are fixedly sleeved on the upper and lower sides of the second mounting groove. A second lead screw 503 is movably sleeved on the left side of the two second fixing plates 502. A second telescopic device 504 is fixedly installed in the middle of the second mounting groove. The second telescopic device 504 is movably sleeved with the second lead screw 503. Second clamping plates 505 are symmetrically slidably sleeved on the upper and lower sides of the second mounting groove. The two telescopic ends on the right side of the second telescopic device 504 are fixedly connected to their adjacent second clamping plates 505. The second clamping plates 505 are threadedly connected to the second lead screw 503. The two first clamping plates 305 have a first V-groove on one side adjacent to each other, and the two second clamping plates 505 have a second V-groove on one side adjacent to each other. Multiple rotors 506 are movably sleeved on the side of the second V-groove. This allows the round shaft to be unable to rotate when the first clamping plate 305 clamps it, but when the second clamping plate 505 clamps it, the round shaft can rotate because the rotors 506 are in contact with it. This enables subsequent drilling and curved surface grooving. The second clamping mechanism 5 has the same structural shape as the first clamping mechanism 3 to facilitate standardized production.

[0023] Please see Figures 1 to 3 As shown, the rotating mechanism 6 includes two telescopic sleeves 601. The two telescopic sleeves 601 are respectively fixedly installed on the side of the two second guide seats 501 away from the connecting block 4. The telescopic ends of the two telescopic sleeves 601 are fixedly installed with driving components 602, and the output ends of the two driving components 602 are fixedly installed with rotating shafts 603. The curved surface of the rotating shaft 603 is fitted with a rubber sleeve, thereby increasing the frictional resistance of the rotating shaft 603. This allows the output end of the driving component 602 to drive the rotating shaft 603 to rotate when the driving component 602 rotates, and the rotating shaft 603 to drive the round shaft in contact with it to rotate.

[0024] Please see Figure 1 and Figure 2 As shown, the first hydraulic mechanism 7 includes a first single-chamber piston cylinder 701, which is fixedly installed on the left side of the upper surface of the mounting base 1. A first one-way valve 702 is fixedly sleeved on the front side of the first single-chamber piston cylinder 701. A first Y-tube 703 is fixedly installed on the left side of the first one-way valve 702. The two ends of the upper part of the first Y-tube 703 are respectively fixedly sleeved on the right side behind the two second telescopic devices 504. A first conduit 704 is fixedly sleeved on the right side of the first one-way valve 702. The top end of the first conduit 704 is fixedly sleeved on the right side behind the first telescopic device 304. Specifically, when the first check valve 702 is activated in the forward direction, its left side opens; when activated in the reverse direction, its right side opens. When the first single-chamber piston cylinder 701 and the first check valve 702 are activated in the forward direction, the hydraulic oil in the cavity of the first single-chamber piston cylinder 701 flows into the second expansion joints 504 on both sides through the first check valve 702 and the first Y-tube 703, causing the extension ends of the second expansion joints 504 to extend. When the first single-chamber piston cylinder 701 is activated in the forward direction and the first check valve 702 is activated in the reverse direction, the hydraulic oil in the cavity of the first single-chamber piston cylinder 701 flows into the left and right expansion joints 504 through the first check valve 702 and the first conduit 704. The first telescopic joints 304 on both sides extend the telescopic end of the first telescopic joint 304, and vice versa. When the first single-chamber piston cylinder 701 is activated in reverse and the first one-way valve 702 is activated in forward, the hydraulic oil flowing into the second telescopic joint 504 flows back to the inner cavity of the first single-chamber piston cylinder 701 through the first Y pipe 703 and the first one-way valve 702. At this time, the telescopic end of the second telescopic joint 504 contracts. When the first single-chamber piston cylinder 701 is activated in reverse and the first one-way valve 702 is activated in reverse, the hydraulic oil in the inner cavity of the first telescopic joint 304 flows back to the inner cavity of the first single-chamber piston cylinder 701 through the first conduit 704 and the first one-way valve 702. At this time, the telescopic end of the first telescopic joint 304 contracts.

[0025] Please see Figure 1 and Figure 2As shown, the cleaning mechanism 8 includes a second water pump 801, which is fixedly installed on the upper surface of the mounting plate 101. A second one-way valve 802 is fixedly sleeved on the front side of the second water pump 801. A second Y-tube 803 is fixedly sleeved on the left side of the second one-way valve 802. The two ends of the upper part of the second Y-tube 803 are respectively fixedly sleeved on the middle of the two second expansion joints 504. A second conduit 804 is fixedly sleeved on the right side of the second one-way valve 802. The top of the second conduit 804 is fixedly sleeved on the middle of the first expansion joint 304. Specifically, when the second check valve 802 is activated in the forward direction, the left side of the second check valve 802 is open; when the second check valve 802 is activated in the reverse direction, the right side of the second check valve 802 is open. When the second water pump 801 is activated and the second check valve 802 is activated in the forward direction, the cleaning fluid drawn by the second water pump 801 flows into the middle of the second expansion joints 504 on both sides through the second check valve 802 and the second Y-pipe 803. Conversely, when the second water pump 801 is activated and the second check valve 802 is activated in the reverse direction, the cleaning fluid drawn by the second water pump 801 flows into the middle of the first expansion joint 304 through the second check valve 802 and the second conduit 804.

[0026] Please see Figure 1 and Figure 2 As shown, the second hydraulic mechanism 9 includes a third single-chamber piston cylinder 901, which is fixedly installed on the right side of the upper surface of the mounting base 1. A third conduit 902 is fixedly sleeved on the front side of the third single-chamber piston cylinder 901, and the two ends of the upper part of the third conduit 902 are respectively fixedly installed on the upper parts of the two telescopic sleeves 601. When the third single-chamber piston cylinder 901 is started in the forward direction, the hydraulic oil in the third single-chamber piston cylinder 901 flows into the inner cavity of the left and right telescopic sleeves 601 through the third conduit 902. The hydraulic oil flowing into the inner cavity of the telescopic sleeves 601 pushes the telescopic end of the telescopic sleeves 601 to extend. The telescopic end of the telescopic sleeves 601 pushes the driving member 602 to move forward. The driving member 602 drives the rotating shaft 603 to move forward. Conversely, when the third single-chamber piston cylinder 901 is started in the reverse direction, the hydraulic oil in the inner cavity of the telescopic sleeves 601 flows back into the inner cavity of the third single-chamber piston cylinder 901. At this time, the telescopic sleeves 601 drive the rotating shaft 603 to move forward through the driving member 602.

[0027] Please see Figure 4 and Figure 5 As shown, the first telescopic device 304 includes a sleeve block 3041, which is slidably sleeved in the middle of the first mounting groove. A sleeve hole 3042 is provided on the right side of the sleeve block 3041. A sleeve rod 3043 is slidably sleeved on the upper and lower sides of the sleeve hole 3042. The sleeve rod 3043 is the telescopic shaft of the first telescopic device 304. A spray hole 3044 is provided in the middle of the sleeve rod 3043. The first conduit 704 is connected to the sleeve hole 3042 so that the hydraulic oil in the inner cavity of the subsequent first single-chamber piston cylinder 701 flows into the inner cavity of the sleeve hole 3042 through the first check valve 702 and the first conduit 704, pushing the sleeve rod 3043 to extend and retract. Please see Figure 1 and Figure 2 As shown, the first Y-tube 703, the first conduit 704, the second Y-tube 803, the second conduit 804 and the third conduit 902 are all made of hydraulically flexible rubber tubing, and the specific arrangement is designed according to the actual situation to avoid affecting the rotation or movement of the device.

[0028] Working principle: When drilling a round shaft is required, the present invention first activates the first single-chamber piston cylinder 701 and the first one-way valve 702 in the forward direction. The hydraulic oil in the inner cavity of the first single-chamber piston cylinder 701 flows into the second telescopic joints 504 on both sides through the first one-way valve 702 and the first Y-tube 703, causing the telescopic ends of the second telescopic joints 504 to extend. The telescopic ends of the second telescopic joints 504 push the two fixedly connected second clamping plates 505 to separate and open. Then, the robotic arm 2 is activated, driving the second clamping mechanism 5 to move in the direction of placing the round shaft and move the round shaft to the middle position of the two second clamping plates 505. Then, the first single-chamber piston cylinder 701 is activated in the reverse direction and the first one-way valve 702 is activated in the forward direction, causing the hydraulic oil flowing into the second telescopic joints 504 to extend. The hydraulic oil flows back to the inner cavity of the first single-chamber piston cylinder 701 through the first Y-pipe 703 and the first one-way valve 702. At this time, the telescopic end of the second telescopic device 504 retracts, and the telescopic end of the second telescopic device 504 pulls the second clamping plate 505 closer together to clamp the round shaft. Then, the robotic arm 2 is started to lift the round shaft. Then, the third single-chamber piston cylinder 901 is started in the forward direction. The hydraulic oil in the third single-chamber piston cylinder 901 is pushed into the inner cavity of the left and right telescopic sleeves 601 through the third conduit 902. The hydraulic oil flowing into the inner cavity of the telescopic sleeves 601 pushes the telescopic end of the telescopic sleeves 601 to extend. The telescopic end of the telescopic sleeves 601 pushes the driving component 602 to move forward. The driving component 602 drives the rotating shaft 603 to move forward and contact the clamped round shaft. Simultaneously, the drive unit 602 is activated, and its output end drives the rotating shaft 603 to rotate. The rotating shaft 603 then drives the clamped cylindrical shaft to rotate. Afterwards, when the second water pump 801 is activated and the second one-way valve 802 is activated in reverse, the cleaning fluid drawn by the second water pump 801 flows into the middle of the first expansion joint 304 through the second one-way valve 802 and the second conduit 804. The cleaning fluid flowing into the middle of the first expansion joint 304 is sprayed onto the surface of the rotating cylindrical shaft to clean the grease from its surface. Then, the first single-chamber piston cylinder 701 and the first one-way valve 702 are activated in reverse, and the first expansion joint... The hydraulic oil in the inner cavity of the telescoping device 304 flows back to the inner cavity of the first single-chamber piston cylinder 701 through the first conduit 704 and the first one-way valve 702. At this time, the telescoping end of the first telescoping device 304 retracts. The first telescoping device 304 drives the first clamping plate 305 to clamp the curved surface of the round shaft after cleaning. Finally, through the mechanical arm 2, one end or curved surface of the round shaft contacts the externally rotating drill bit to realize drilling of the round shaft. This solves the technical problem that the existing machine clamping device is prone to slippage when clamping a round shaft with a protective oil covering the surface, which causes the round shaft to rotate during the drilling process and causes processing failure. Furthermore, when it is necessary to groove the curved surface of the circular shaft, the present invention reverses the operation of the first single-chamber piston cylinder 701 and the first one-way valve 702, causing the telescopic end of the first telescopic member 304 to retract, thus clamping the circular shaft with the first clamping mechanism 3. Then, the second water pump 801 is activated and the second one-way valve 802 is activated in the forward direction, allowing cleaning fluid to flow into the middle of the left and right second telescopic members 504 to clean both ends of the circular shaft. Then, the first single-chamber piston cylinder 701 is activated in the reverse direction and the first one-way valve 702 is activated in the forward direction, causing the first clamping mechanism 3 to clamp the circular shaft. When the telescopic end of the second telescopic device 504 retracts, the second clamping mechanism 5 clamps the cleaned round shaft. Then, the first single-chamber piston cylinder 701 is activated in the forward direction and the first one-way valve 702 is activated in the reverse direction, causing the telescopic end of the first telescopic device 304 to extend. At this time, the first clamping mechanism 3 stops clamping the round shaft. Then, the third single-chamber piston cylinder 901 is activated in the forward direction. The second hydraulic mechanism 9 drives the telescopic end of the telescopic sleeve 601 to push the driving component 602 forward. The driving component 602 drives the rotating shaft 603 forward to contact the clamped round shaft. Simultaneously, the drive unit 602 is activated, and its output end drives the rotating shaft 603 to rotate. The rotating shaft 603 then drives the clamped circular shaft to rotate. Next, the robotic arm 2 is activated, and the robotic arm 2 drives the rotating circular shaft surface to contact the externally fixed cutting tool. The cutting tool slots the circular shaft surface. This achieves the simultaneous clamping of the circular shaft by the second clamping mechanism 5 and the rotating mechanism 6, while driving the circular shaft to rotate and contact the externally fixed cutting tool, thus slotting the circular shaft surface. This solves the problem of existing cutting devices that require the robotic arm 2 to first install the circular shaft onto the external clamping device, and then drive the circular shaft to rotate and contact the fixed tool for slotting, resulting in increased processes and reduced efficiency.
