Description

Technical Field

[0001] This application relates to the field of conveying device technology, and in particular to a loading fixture for a pipe fitting processing platform. Background Technology

[0002] In the CNC machining process of shaft parts, in order to improve the working efficiency of the equipment, the workpiece is usually transported by a loading fixture in conjunction with a robot.

[0003] For some long stepped shaft parts, their length makes it easy for them to be placed at a relatively tilted position on the loading fixture. That is, the axis of the shaft part is tilted relative to the conveying direction of the loading fixture. This is not conducive to detecting the orientation of the shaft part, and it is also not conducive to the robot arm to clamp and rotate the part, thus affecting the loading efficiency of the loading fixture. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide a loading fixture for a pipe fitting processing platform to improve the loading efficiency of the loading fixture.

[0005] To achieve the above objectives, this application adopts the following technical solution: A loading fixture for a pipe fitting processing platform is used to load shaft-type workpieces. It includes a loading mechanism, a clamping mechanism, an orientation detection mechanism, and an output mechanism. The loading mechanism includes a loading channel in which the shaft-type workpiece moves. The orientation detection mechanism includes a swing table and a detection component. The swing table can swing under the weight of the shaft-type workpiece, and the detection component is connected to the swing table to detect the swing direction. The output mechanism includes an output channel and a support member. The support member is slidably mounted in the output channel and at least partially abuts against the circumferential sidewall of the shaft-type workpiece to align the axis of the shaft-type workpiece with the extending direction of the loading channel. The clamping mechanism includes a rotary manipulator and a moving component for moving the rotary manipulator. The moving component is connected to the rotary manipulator, and through the cooperation of the rotary manipulator and the moving component, the shaft-type workpiece is sequentially moved from the loading mechanism to the orientation detection mechanism and the output mechanism. The rotary manipulator includes a first clamping component for clamping the shaft-type workpiece and a rotating component for rotating the first clamping component. The first clamping component is rotatably mounted on the moving component via the rotating component.

[0006] Furthermore, the orientation detection mechanism also includes ball bearings, and a ball bearing channel is formed inside the swing table. The ball bearings are movably installed in the ball bearing channel, and the ball bearings are adapted to the detection component. The swing direction of the swing table is detected by detecting the position of the ball bearings through the detection component.

[0007] Furthermore, the detection assembly includes two contact sensors and two mounting plates, with the two mounting plates respectively mounted at both ends of the swing stage, and the two contact sensors respectively mounted at both ends of the swing stage via the mounting plates, with the contact sensors extending at least partially into the ball channel.

[0008] Furthermore, a placement channel is formed within the swing table, and the mounting plate extends at least partially to the end of the placement channel to confine the shaft-type workpiece within the placement channel.

[0009] Furthermore, the depth of the placement channel is less than the radius of the shaft-type workpiece.

[0010] Furthermore, when the shaft-type workpiece is located in the feeding channel, the shaft-type workpiece is inclined relative to the extension direction of the feeding channel, and the inclination angle of the shaft-type workpiece axis relative to the extension direction of the feeding channel is defined as the first inclination angle; when the shaft-type workpiece is located on the swing table, the extension direction of the swing table is inclined relative to the extension direction of the feeding channel, and the inclination angle of the extension direction of the swing table relative to the extension direction of the feeding channel is defined as the second inclination angle; the values ​​of the first inclination angle and the second inclination angle are consistent.

[0011] Furthermore, the output mechanism also includes a push cylinder, which is connected to the support member and has a degree of freedom of movement relative to the support member.

[0012] Furthermore, a connecting shaft is formed on the support member, and a limit nut is installed on the connecting shaft; a connecting plate is formed on the push cylinder, the connecting plate is slidably connected to the connecting shaft, and the connecting plate is located between the limit nut and the support member.

[0013] Furthermore, the output mechanism also includes a positioning baffle, which is located at the end of the output channel away from the pushing cylinder.

[0014] Furthermore, the clamping mechanism also includes a fixed manipulator, which is adapted to the feeding mechanism and the orientation detection mechanism respectively, to move the shaft workpiece from the feeding mechanism to the orientation detection mechanism; and a rotating manipulator, which is adapted to the orientation detection mechanism and the output mechanism respectively, to move the shaft workpiece from the orientation detection mechanism to the output mechanism.

[0015] The orientation detection mechanism facilitates the detection of the orientation of shaft-type workpieces, allowing the rotating robot to adjust the orientation of the workpieces being transported to the output mechanism. This facilitates the subsequent clamping of the workpieces by the robot, improving the loading efficiency of the loading fixture. Simultaneously, the support structure ensures that the axis of the shaft-type workpiece is parallel to the extension direction of the loading channel, further facilitating the clamping of the workpieces by the robot and further enhancing the loading efficiency of the loading fixture.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figure 1As shown, the present application provides a loading fixture for a pipe fitting processing platform, which is used to load a shaft workpiece 1. The shaft workpiece 1 includes at least two stepped sections, and when such a shaft workpiece 1 is placed on a horizontal surface, its axis is inclined relative to the horizontal surface.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, as one implementation, this application provides a loading fixture for a pipe fitting processing platform, including a loading mechanism 2, an orientation detection mechanism 3, an output mechanism 4, a clamping mechanism 5, and a base 6. The loading mechanism 2, the orientation detection mechanism 3, the output mechanism 4, and the clamping mechanism 5 are respectively mounted on the base 6, and the clamping mechanism 5 is located above the loading mechanism 2, the orientation detection mechanism 3, and the output mechanism 4. The shaft workpiece 1 is moved from the loading mechanism 2 to the orientation detection mechanism 3 and the output mechanism 4 in sequence through the clamping mechanism 5. An external robot arm moves the shaft workpiece 1 from the output mechanism 4 to the CNC machine tool.

[0027] It should be noted that the external robot refers to a robot other than the loading fixture, which moves the shaft workpiece 1 from the loading fixture to the CNC machine tool fixture.

[0028] The feeding mechanism 2 includes a conveyor belt 202 and a baffle assembly 203. The conveyor belt 202 and the baffle assembly 203 are respectively installed on the base 6. The conveyor belt 202 and the baffle assembly 203 together form a feeding channel 201. When the conveyor belt 202 is working, the shaft workpiece 1 moves in the feeding channel 201 to facilitate the conveying of the shaft workpiece 1.

[0029] The baffle assembly 203 has an opening 2031 at the end near the detection mechanism 3 to prevent the clamping mechanism 5 from interfering with the baffle assembly 203 when clamping the shaft workpiece 1.

[0030] The orientation detection mechanism 3 includes a swing table 301 and a detection component 302. Under the weight of the shaft workpiece 1, the swing table 301 can swing relative to the base 6. The detection component 302 is connected to the swing table 301 and detects the swing direction of the swing table 301 so as to determine the orientation of the shaft workpiece 1 placed on the swing table 301.

[0031] It should be noted that the swing center of the swing table 301 is located at the midpoint of the length of the shaft workpiece 1. Since the shaft workpiece 1 is a stepped shaft structure, the center of gravity of the shaft workpiece 1 is deviated from the midpoint of the length of the shaft workpiece 1, which causes the swing table 301 to swing relative to the shaft workpiece 1. Under normal conditions, the swing table 301 is tilted towards the end of the shaft workpiece 1 with the larger diameter.

[0032] The output mechanism 4 includes an output channel 401 and a support member 402. The support member 402 is slidably installed in the output channel 401 and at least partially abuts against the circumferential side wall of the shaft workpiece 1 so that the axis of the shaft workpiece 1 is parallel to the extension direction of the feeding channel 201, so as to facilitate the subsequent clamping of the workpiece by the robot arm and improve the feeding efficiency and feeding stability of the feeding fixture.

[0033] The clamping mechanism 5 includes a rotary manipulator 501 and a moving component 502 for moving the rotary manipulator 501. The moving component 502 is connected to the rotary manipulator 501. Through the cooperation of the rotary manipulator 501 and the moving component 502, the shaft workpiece 1 is moved from the feeding mechanism 2 to the detection mechanism 3 and the output mechanism 4 in sequence.

[0034] The rotary manipulator 501 includes a first clamping assembly 5011 and a rotating component 5012. The first clamping assembly 5011 is used to clamp the shaft workpiece 1, and the rotating component 5012 is used to rotate the first clamping assembly 5011. The first clamping assembly 5011 is rotatably mounted on the moving assembly 502 via the rotating component 5012. The rotating component 5012 can rotate or remain stationary according to the detection result of the orientation detection mechanism 3, so as to ensure that the shaft workpiece 1 conveyed to the output mechanism 4 has a consistent orientation.

[0035] like Figure 6 As shown, in one implementation, the orientation detection mechanism 3 also includes a ball bearing 303. A ball bearing channel 3011 is formed in the swing table 301. The ball bearing channel 3011 extends along the length of the swing table 301. The ball bearing 303 is movably installed in the ball bearing channel 3011 and is adapted to the detection component 302. When the swing table 301 swings, the ball bearing 303 moves toward one end of the swing table 301 until it comes into contact with the detection component 302 located on one side of the swing table 301, thereby triggering the detection component 302 at that position. The triggered detection component 302 determines the position of the ball bearing 303 and the swing direction of the swing table 301, thereby determining the orientation of the shaft workpiece 1. This allows the shaft workpiece 1 to be rotated or kept in its initial state according to the orientation of the shaft workpiece 1 required by this feeding fixture.

[0036] In one implementation, the detection component 302 includes two contact sensors 3021 and two mounting plates 3022. The two mounting plates 3022 are respectively mounted at both ends of the swing table 301, and the two contact sensors 3021 are respectively mounted at both ends of the swing table 301 via the mounting plates 3022. The contact sensors 3021 extend at least partially into the ball channel 3011.

[0037] When the shaft workpiece 1 is placed on the swing table 301, the swing table 301 swings toward the end of the shaft workpiece 1 with a larger diameter. The ball 303 abuts against the contact sensor 3021 near the end of the shaft workpiece 1 with a larger diameter, causing the contact sensor 3021 to be triggered.

[0038] Preferably, the detection component 302 includes a contact sensor 3021 and two mounting plates 3022. The two mounting plates 3022 are respectively mounted on both ends of the swing table 301. The contact sensor 3021 is mounted on one of the mounting plates 3022. When the ball 303 triggers the contact sensor 3021, it indicates that the shaft workpiece 1 is facing the wrong direction and needs to be rotated 180° by the rotary manipulator 501.

[0039] As one implementation, the swing table 301 is a V-shaped part, so that a placement channel 3012 is formed inside the swing table 301. The mounting piece 3022 extends at least partially to the end of the placement channel 3012, so as to limit the shaft workpiece 1 within the placement channel 3012 by the mounting piece 3022, preventing the shaft workpiece 1 from sliding out of the swing table 301 during the swinging process, and ensuring the stability of the use of this feeding fixture.

[0040] As one implementation method, the depth of the placement channel 3012 is less than the radius of the shaft workpiece 1 to prevent the rotary manipulator 501 from interfering with the swing table 301 when it clamps the shaft workpiece 1.

[0041] As one implementation, when the shaft workpiece 1 is located in the feeding channel 201, the shaft workpiece 1 is inclined relative to the extension direction of the feeding channel 201, and the inclination angle of the axis of the shaft workpiece 1 relative to the extension direction of the feeding channel 201 is defined as the first inclination angle; when the shaft workpiece 1 is located on the swing table 301, the extension direction of the swing table 301 is inclined relative to the extension direction of the feeding channel 201, and the inclination angle of the extension direction of the swing table 301 relative to the extension direction of the feeding channel 201 is defined as the second inclination angle; the value of the first inclination angle is the same as the value of the second inclination angle.

[0042] When the shaft workpiece 1 is placed on the swing table 301, after the swing table 301 swings, the axis of the shaft workpiece 1 becomes horizontal, so that the rotating robot arm 501 can clamp the shaft workpiece 1.

[0043] As one implementation, the orientation detection mechanism 3 also includes a mounting base 304. The swing table 301 is rotatably mounted on the mounting base 304 via a rotating shaft. A limiting protrusion is formed on the end face of the mounting base 304 facing the swing table 301. The swing angle of the swing table 301 is limited by the limiting protrusion.

[0044] like Figure 4 and Figure 5As shown, in one implementation, along the vertical projection, the output mechanism 4 extends at least partially to the outside of the clamping mechanism 5, so that an external robot arm can clamp the shaft-like workpiece 1 on the output mechanism 4.

[0045] To facilitate the movement of the shaft workpiece 1 to the part of the output mechanism 4 that extends beyond the clamping mechanism 5, the output mechanism 4 also includes a pushing cylinder 403. The pushing cylinder 403 is connected to the support member 402. When the shaft workpiece 1 is moved, the pushing cylinder 403 works, simultaneously pushing the shaft workpiece 1 and the support member 402 to move. When the pushing cylinder 403 is reset, it drives the support member 402 to reset, so that the small diameter section of the subsequent shaft workpiece 1 can abut against the support member 402, thereby keeping the axis of the shaft workpiece 1 in a horizontal state.

[0046] As one implementation, the output mechanism 4 also includes a positioning baffle 404, which is arranged at the end of the output channel 401 away from the push cylinder 403, so as to position the shaft workpiece 1 through the positioning baffle 404, so as to allow the external robot to clamp the shaft workpiece 1 on the output mechanism 4.

[0047] To ensure that the external robot can stably grip the shaft workpiece 1 on the output mechanism 4, after the push cylinder 403 abuts the shaft workpiece 1 against the positioning baffle 404, it needs to retract a certain distance to prevent the push cylinder 403 and the positioning baffle 404 from clamping the shaft workpiece 1.

[0048] As one implementation method, in order to prevent the support member 402 from separating from the shaft workpiece 1 during the retraction process of the push cylinder 403, the push cylinder 403 has a degree of freedom of movement relative to the support member 402, ensuring that the support member 402 remains stationary during the retraction process of the push cylinder 403.

[0049] In one implementation, a connecting shaft 4021 is formed on the support member 402, and a limit nut 4022 is installed on the connecting shaft 4021; a connecting plate 4031 is formed on the push cylinder 403, the connecting plate 4031 is slidably connected to the connecting shaft 4021, and the connecting plate 4031 is located between the limit nut 4022 and the support member 402.

[0050] When pushing the shaft workpiece 1, the output shaft of the pushing cylinder 403 abuts against the support member 402 to push the support member 402 to move. During the retraction of the pushing cylinder 403, the connecting plate 4031 slides relative to the connecting shaft 4021, so that the support member 402 is in a stationary state. During the reset process of the pushing cylinder 403, the connecting plate 4031 abuts against the limit nut 4022, thereby driving the support member 402 to reset.

[0051] like Figure 7As shown, in one implementation, the first clamping assembly 5011 includes a first pneumatic finger 50111 and a clamping plate 50112. The clamping plate 50112 is mounted on the first pneumatic finger 50111 and is driven by the first pneumatic finger 50111.

[0052] A V-shaped groove is formed on the clamping plate 50112. The shaft workpiece 1 is clamped through the V-shaped groove to ensure the clamping stability of the shaft workpiece 1 and to prevent the shaft workpiece 1 from falling off the first clamping assembly 5011 when the rotating part 5012 rotates on the first clamping assembly 5011.

[0053] The rotating component 5012 is a rotary cylinder and is mounted on the moving component 502 so as to drive the first clamping component 5011 to rotate via the rotating component 5012.

[0054] As one implementation, the clamping mechanism 5 also includes a fixed manipulator 503, which is adapted to the feeding mechanism 2 and the orientation detection mechanism 3 respectively, so as to move the shaft workpiece 1 from the feeding mechanism 2 to the orientation detection mechanism 3; and a rotating manipulator 501 is adapted to the orientation detection mechanism 3 and the output mechanism 4 respectively, so as to move the shaft workpiece 1 from the orientation detection mechanism 3 to the output mechanism 4.

[0055] The fixed manipulator 503 includes a connecting column 5031, a second pneumatic finger 5032, and a clamping plate 5033. The second pneumatic finger 5032 is mounted on the moving component 502 via the connecting column 5031. The clamping plate 5033 is connected to the second pneumatic finger 5032, and the clamping plate 5033 is driven by the second pneumatic finger 5032 to clamp the shaft workpiece 1.

[0056] Furthermore, a rubber pad 5034 is installed on the clamping plate 5033, and the inclined shaft workpiece 1 is clamped by the deformation of the rubber pad 5034.

[0057] In one implementation, the moving component 502 includes a guide plate 5021, a lifting cylinder 5022, a translation cylinder 5023, a mounting plate 5024, and a fixed bracket 5025. The fixed bracket 5025 is fixed on the base 6. The guide plate 5021 is slidably mounted on the moving bracket 5025 via a slide rail. The translation cylinder 5023 is fixed on the moving bracket 5025 and connected to the guide plate 5021 to drive the guide plate 5021 to translate. The lifting cylinder 5022 is mounted on the guide plate 5021, and the output shaft of the lifting cylinder 5022 is connected to the mounting plate 5024 to drive the mounting plate 5024 to lift.

[0058] The connecting column 5031 and the rotating component 5012 are respectively mounted on the mounting plate 5024.

[0059] As one implementation method, the spacing between the center positions of the feeding channel 201 and the placement channel 3012 is the same as the spacing between the center positions of the placement channel 3012 and the output channel 401.

[0060] Meanwhile, the distance between the clamping center position of the fixed robot 503 and the clamping center position of the rotating robot 501 is consistent with the distance between the center position of the feeding channel 201 and the center position of the placement channel 3012.

[0061] So that while the fixed robot arm 503 can hold the shaft workpiece 1 in the feeding channel 201, the rotating robot arm 501 can also hold the shaft workpiece 1 in the placement channel 3012.

[0062] Similarly, while the fixed robot 503 places the shaft-type workpiece 1 in the placement channel 3012, the rotating robot 501 can place the shaft-type workpiece 1 in the output channel 401.

[0063] The above settings can effectively improve the working efficiency of the clamping mechanism 5.

[0064] Finally, it should be noted that the above are only some preferred embodiments of this application and are not intended to limit this application. Although this application 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
