Description

Technical Field

[0001] This utility model relates to the technical field of powder metallurgy shaft processing equipment, and in particular to a powder metallurgy shaft shaping fixture. Background Technology

[0002] Powder metallurgy is an advanced manufacturing process that involves pressing metal powder into shape and sintering it into desired parts (such as shafts). It offers advantages such as high material utilization and the ability to produce complex shapes. Powder metallurgy shafts are common small to medium-sized rotating components widely used in the automotive and machinery industries, requiring high dimensional accuracy and surface quality. However, after forming, powder metallurgy shafts are susceptible to sintering deformation or residual stress, leading to dimensional deviations such as irregular shaft diameters and insufficient end-face flatness. These issues affect the product's assembly accuracy and performance. Currently, the forming process for powder metallurgy shafts suffers from low automation and unstable precision. Therefore, a powder metallurgy shaft forming fixture is urgently needed to address these problems. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a powder metallurgy shaft shaping fixture, which solves the technical problems of low automation and low shaping efficiency in the existing powder metallurgy shaft shaping.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A powder metallurgy spindle forming fixture for shaping powder metallurgy spindles includes: a worktable, wherein the worktable is provided with:

[0006] A pair of material-carrying components, the pair of material-carrying components including: a feeding component and a discharging component, the feeding component and the discharging component being spaced apart in the X direction, the feeding component and the discharging component being used for feeding and discharging powder metallurgy rotating shafts respectively;

[0007] The shaping station includes a first placement platform and a pressure seat. The pressure seat is positioned directly opposite the first placement platform. The pressure seat includes a receiving cavity, which is adapted to the preset external dimensions of the powder metallurgy rotating shaft. A pressure block is elastically floating inside the receiving cavity. When the powder metallurgy rotating shaft enters the receiving cavity, the pressure block abuts against the upper end of the powder metallurgy rotating shaft in the vertical direction.

[0008] The inspection station includes: a second placement table and a vision sensor. The vision sensor is movably and adjustablely disposed on the upper end of the second placement table and is used to detect the shape parameters of the powder metallurgy rotating shaft placed on the second placement table.

[0009] Feeding module, which is used to sequentially transfer the powder metallurgy rotating shaft on the feeding component, the first placement table, and the second placement table;

[0010] Transfer component, which is used to transfer the powder metallurgy rotating shaft on the second placement table to the blanking component.

[0011] Based on the above structure, the principle of the powder metallurgy rotating shaft shaping fixture is as follows: First, place the powder metallurgy rotating shaft to be shaped in the feeding component. After the feeding component transfers the powder metallurgy rotating shaft to the preset position, the feeding module starts and grabs a single powder metallurgy rotating shaft on the feeding component. Subsequently, the feeding module places the powder metallurgy rotating shaft on the first placement table, and the pressing seat moves towards the first placement table until the powder metallurgy rotating shaft completely enters the accommodation cavity. During this process, the pressing block abuts against the upper end of the powder metallurgy rotating shaft in the vertical direction. As the pressing seat continues to descend, the pressing block applies an axial shaping force to the powder metallurgy rotating shaft through floating pressure to correct the external dimension of the powder metallurgy rotating shaft. After shaping, the pressing seat starts to reset. Since the pressing block is elastically floating, under the action of the elastic force, the shaped powder metallurgy rotating shaft is extruded from the accommodation cavity, and the pressing seat is separated from the powder metallurgy rotating shaft. Then, the feeding module grabs the shaped powder metallurgy rotating shaft and transfers it from the first placement table to the second placement table. The vision sensor moves and adjusts to the appropriate detection position according to the specifications of the powder metallurgy rotating shaft (such as aligning with the outer diameter of the rotating shaft), the vision sensor takes an external image of the powder metallurgy rotating shaft, analyzes and detects parameters such as its actual size and surface defects, and compares with the preset standard to determine whether it is qualified. After the detection is completed, the transfer component grabs the powder metallurgy rotating shaft on the second placement table and transfers it to the blanking component, and the operator screens the powder metallurgy rotating shaft according to the detection results of the vision sensor.

[0012] Furthermore, in this application, a powder metallurgy spindle forming fixture is provided on the worktable, wherein a pressure stabilizing component is provided, the pressure stabilizing component includes: a first mounting frame, a first linear drive device, and a pressing block. The first mounting frame is mounted on the worktable, the first linear drive device is mounted on the first mounting frame, and the movable end of the first linear drive device is connected to the pressing block. When the material conveying module clamps the powder metallurgy spindle from the feeding component, the pressing block abuts against the upper end of the powder metallurgy spindle. As a preferred embodiment of this application, a powder metallurgy shaft shaping fixture is provided. When the feeding module clamps the powder metallurgy shaft on the feeding assembly, the first linear drive device is activated, driving the pressing block to move to contact the powder metallurgy shaft. Then, the feeding module begins to clamp the powder metallurgy shaft. After the feeding module completes the clamping, the first linear drive device drives the pressing block to move vertically upward to reset, and the pressing block disengages from the powder metallurgy shaft, avoiding interference with the subsequent transmission action of the feeding module. Since the powder metallurgy shaft is relatively brittle, the stabilizing assembly is used to clamp the powder metallurgy shaft to prevent the powder metallurgy shaft from shaking or tilting, and to prevent the powder metallurgy shaft from cracking or slag falling off.

[0013] Furthermore, in this application, a powder metallurgy rotating shaft shaping fixture includes a feeding module comprising: a base plate and a mounting plate. The base plate is slidably mounted on a worktable in the X direction. A pair of guide posts are provided on the base plate, and the pair of guide posts are spaced apart on the base plate in the X direction. The mounting plate is sleeved on the pair of guide posts. A second linear drive device is provided between the pair of guide posts. The second linear drive device is mounted on the base plate, and the drive end of the second linear drive device is connected to the mounting plate. A pair of clamping components are spaced apart in the X direction on the mounting plate. The distance between the pair of clamping components is consistent with the distance between adjacent pairs of the feeding assembly, the first placement table, and the second placement table. A third linear drive device is provided on the worktable, and the third linear drive device is used to drive the base plate to reciprocate between the feeding assembly, the first placement table, and the second placement table. As a preferred embodiment of this application, a powder metallurgy spindle shaping fixture is provided. A third linear drive device drives a base plate to slide along the X-direction. A pair of clamping components align and synchronously clamp the powder metallurgy spindle on the feeding assembly and the powder metallurgy spindle on the first placement table, respectively. After clamping, a second linear drive device is activated, and a mounting plate rises axially along the guide column, causing the pair of powder metallurgy spindles to disengage from the feeding assembly and the first placement table, respectively. Then, the base plate slides along the X-direction, positioning the clamping component that clamped the powder metallurgy spindle on the feeding assembly above the first placement table and the other clamping component above the second placement table. Next, the mounting plate descends, and the pair of clamping components open and reset, placing the powder metallurgy spindle on the corresponding first and second placement tables. The mounting plate then rises, completing the material transfer. The fixture utilizes a matching design between the spacing of the clamping components and the spacing between workstations to achieve "material handling and placement." Parallel operation reduces idle time and improves transfer efficiency; guide columns ensure stable lifting and lowering of the mounting plate; through the coordinated control of the third and second linear drive devices, the material conveying module achieves fully automatic cyclic operation without manual intervention, making it suitable for mass production.

[0014] Furthermore, in this application, a powder metallurgy shaft shaping fixture includes a clamping component comprising a pair of grippers, each gripper having an anti-slip wear layer between it and the powder metallurgy shaft. As a preferred embodiment of this application, the anti-slip wear layer in this powder metallurgy shaft shaping fixture prevents slippage or damage when the grippers hold the powder metallurgy shaft, ensuring a secure gripping process without detachment. Furthermore, the design of the anti-slip wear layer prevents the grippers from directly scratching the surface of the powder metallurgy shaft.

[0015] Furthermore, in a powder metallurgy spindle forming fixture of this application, the first placement table is provided with a receiving groove adapted to the powder metallurgy spindle, the receiving groove being used to accommodate the powder metallurgy spindle. As a preferred embodiment of this application, in a powder metallurgy spindle forming fixture of this application, the receiving groove is used to limit the powder metallurgy spindle placed on the first placement table, preventing radial displacement of the powder metallurgy spindle during the forming process.

[0016] Furthermore, in this application, a powder metallurgy spindle forming fixture includes a forming station further comprising: a second mounting frame and a driving device. The second mounting frame is mounted on a worktable, and the driving device is mounted on the second mounting frame. The driving end of the driving device is connected to a pressure base. An elastic element is provided inside the receiving cavity, and both ends of the elastic element are connected to the pressure base and the pressure block, respectively. As a preferred embodiment of this application, in this powder metallurgy spindle forming fixture, when the driving device is activated, the pressure base descends, and the pressure block first contacts the upper end of the powder metallurgy spindle. The elastic element is compressed as the pressure base continues to descend, preventing rigid pressure from causing the upper end of the powder metallurgy spindle to crack. During the upward movement of the pressure base, the elastic element begins to reset, pushing the pressure block to squeeze the powder metallurgy spindle out of the receiving cavity, ensuring that the powder metallurgy spindle smoothly disengages from the receiving cavity and avoiding interference with the efficiency of the next forming operation.

[0017] Furthermore, in this application, a powder metallurgy shaft shaping fixture includes a testing station comprising a third mounting frame and a moving module. The third mounting frame is mounted on a second placement platform, and the moving module is mounted on the third mounting frame. The vision sensor is mounted on the third mounting frame, and the moving module is used for adjusting the movement of the vision sensor in the X-direction and vertical direction. As a preferred embodiment of this application, the moving module in this powder metallurgy shaft shaping fixture is used to adjust the vision sensor in the X-direction and vertical direction to accommodate powder metallurgy shafts of different lengths, ensuring that the vision sensor can be accurately aligned with the powder metallurgy shaft. The shooting distance is adjusted according to the diameter or height of the powder metallurgy shaft to ensure the clarity of the vision sensor's image.

[0018] Furthermore, in this application, a powder metallurgy spindle shaping fixture is provided, wherein the material transfer assembly includes a turntable and a clamping assembly. The turntable is rotatably adjustable on a worktable, and a fourth linear drive device is provided on the turntable. The clamping assembly is installed on the movable end of the fourth linear drive device. The unloading assembly includes a conveyor belt and a defective product box, wherein the conveyor belt and the defective product box are respectively used to collect qualified powder metallurgy spindles and unqualified powder metallurgy spindles. As a preferred embodiment of this application, a powder metallurgy spindle shaping fixture is provided. After the vision sensor completes the shape detection of the powder metallurgy spindle, the turntable rotates to a preset angle, aligning the clamping component with the powder metallurgy spindle on the second placement platform. The fourth linear drive device drives the clamping component to extend and clamp the powder metallurgy spindle. After clamping, the fourth linear drive device drives the clamping component to retract and reset. When the powder metallurgy spindle is qualified, the turntable rotates to the angle corresponding to the unloading component, and the fourth linear drive device drives the clamping component to extend and place the qualified powder metallurgy spindle on the unloading component. When the powder metallurgy spindle is unqualified, the turntable rotates to the angle corresponding to the defective box, and the fourth linear drive device drives the clamping component to extend and release the unqualified powder metallurgy spindle. Then the clamping component resets. After completing one transfer operation, the turntable rotates back to the initial position, waiting for the next powder metallurgy spindle to be inspected. The above steps are repeated to achieve continuous transfer operation.

[0019] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0020] The purpose of this invention is to provide a powder metallurgy spindle forming fixture. Through the coordinated operation of a feeding component, forming station, inspection station, material conveying module, material transfer component, and unloading component, it achieves automated forming and inspection of powder metallurgy spindles, improving production efficiency and product qualification rate to meet the needs of mass production. Simultaneously, the elastically floating pressure block within the pressure seat applies axial forming force to the powder metallurgy spindle, preventing spindle breakage caused by rigid pressure. Furthermore, the floating characteristic of the pressure block helps the formed powder metallurgy spindle detach from the pressure seat, further improving production efficiency. The fixture is adjustable via a movable vision sensor to adapt to the shape inspection of spindles of different specifications, improving its versatility. The material conveying module and material transfer component facilitate automatic transfer and material handling between stations, achieving batch forming, high-quality screening, and efficient processing of powder metallurgy spindles while preventing product damage.

Detailed Implementation

[0027] like Figure 1 , 2 As shown in Figure 3, a powder metallurgy shaft shaping fixture is used to shape a powder metallurgy shaft 1, comprising: a worktable 2, wherein the worktable 2 is provided with:

[0028] A pair of material-carrying components 3, each pair of material-carrying components 3 includes: a feeding component 31 and a discharging component 32, the feeding component 31 and the discharging component 32 being spaced apart in the X direction, the feeding component 31 and the discharging component 32 being used for feeding and discharging the powder metallurgy rotating shaft 1 respectively;

[0029] The shaping station 4 includes a first placement platform 41 and a pressure seat 42. The pressure seat 42 is positioned directly opposite the first placement platform 41. The pressure seat 42 includes a receiving cavity 420. The receiving cavity 420 is adapted to the preset external dimensions of the powder metallurgy rotating shaft 1. A pressure block 421 is elastically floating inside the receiving cavity 420. When the powder metallurgy rotating shaft 1 enters the receiving cavity 420, the pressure block 421 abuts against the upper end of the powder metallurgy rotating shaft 1 in the vertical direction.

[0030] Inspection station 5 includes: a second placement table 51 and a vision sensor 52. The vision sensor 52 is movably and adjustablely disposed on the upper end of the second placement table 51. The vision sensor 52 is used to detect the shape parameters of the powder metallurgy rotating shaft 1 placed on the second placement table 51.

[0031] Material conveying module 6, which is used to sequentially transfer the powder metallurgy rotating shaft 1 on the feeding assembly 31, the first placement platform 41, and the second placement platform 51;

[0032] The material transfer assembly 7 is used to transfer the powder metallurgy rotating shaft 1 on the second placement stage 51 to the unloading assembly 32.

[0033] Based on the above structure, the principle of the powder metallurgy rotating shaft shaping fixture is as follows: First, the powder metallurgy rotating shaft 1 to be shaped is placed in the feeding assembly 31. After the feeding assembly 31 moves the powder metallurgy rotating shaft 1 to a preset position, the conveying module 6 is activated to grab a single powder metallurgy rotating shaft 1 from the feeding assembly 31. Subsequently, the conveying module 6 places the powder metallurgy rotating shaft 1 on the first placement platform 41, and the pressure seat 42 moves closer to the first placement platform 41 until the powder metallurgy rotating shaft 1 is completely inserted into the receiving cavity 420. During this process, the pressure block 421 abuts against the upper end of the powder metallurgy rotating shaft 1 in the vertical direction. As the pressure seat 42 continues to descend, the pressure block 421 applies axial shaping force to the powder metallurgy rotating shaft 1 through floating pressure, correcting the external dimensions of the powder metallurgy rotating shaft 1. After the shaping is completed, the pressure seat 42 begins to reset. 421 is set with elastic floating. Under the action of elastic force, the pressure block 421 squeezes the shaped powder metallurgy shaft 1 out of the receiving cavity 420, and the pressure seat 42 is separated from the powder metallurgy shaft 1. Then, the material conveying module 6 grabs the shaped powder metallurgy shaft 1 and transfers it from the first placement table 41 to the second placement table 51. The vision sensor 52 moves and adjusts to a suitable detection position (such as aligning with the outer diameter of the shaft) according to the specifications of the powder metallurgy shaft 1. The vision sensor 52 takes an image of the shape of the powder metallurgy shaft 1, analyzes and detects its actual size, surface defects and other parameters, and compares them with the preset standard to determine whether it is qualified. After the detection is completed, the material transfer component 7 grabs the powder metallurgy shaft 1 on the second placement table 51 and transfers it to the unloading component 32. The operator screens the powder metallurgy shaft 1 according to the detection results of the vision sensor 52.

[0034] In this embodiment, the workbench 2 is provided with a pressure stabilizing component 8, which includes a first mounting frame 81, a first linear drive device 82, and a pressing block 83. The first mounting frame 81 is disposed on the workbench 2, and the first linear drive device 82 is mounted on the first mounting frame 81. The movable end of the first linear drive device 82 is connected to the pressing block 83. When the material conveying module 6 clamps the powder metallurgy rotating shaft 1 from the feeding component 31, the pressing block 83 abuts against the upper end of the powder metallurgy rotating shaft 1. When the feeding module 6 clamps the powder metallurgy shaft 1 on the feeding assembly 31, the first linear drive device 82 is activated, driving the pressing block 83 to move until it contacts the powder metallurgy shaft 1. Then, the feeding module 6 begins to clamp the powder metallurgy shaft 1. After the feeding module 6 completes the clamping, the first linear drive device 82 drives the pressing block 83 to move vertically upwards and reset, disengaging the pressing block 83 from the powder metallurgy shaft 1 to avoid interfering with the subsequent transmission actions of the feeding module 6. Since the powder metallurgy shaft 1 is relatively brittle, the stabilizing assembly 8 is used to prevent the powder metallurgy shaft 1 from shaking or tilting when clamping it, thus preventing the powder metallurgy shaft 1 from cracking or flaking. The first linear drive device 82 is a cylinder.

[0035] In this embodiment, the material conveying module 6 includes: a base plate 61 and a mounting plate 62. The base plate 61 is slidably mounted on the worktable 2 in the X direction. A pair of guide posts 63 are provided on the base plate 61, and the pair of guide posts 63 are spaced apart on the base plate 61 in the X direction. The mounting plate 62 is sleeved on the pair of guide posts 63. A second linear drive device 64 is provided between the pair of guide posts 63. The second linear drive device 64 is mounted on the base plate 61, and the drive end of the second linear drive device 64 is connected to the mounting plate 62. A pair of clamping members 65 are spaced apart in the X direction on the mounting plate 62. The distance between the pair of clamping members 65 is consistent with the distance between any two adjacent feeding components 31, the first placement platform 41, and the second placement platform 51. A third linear drive device 66 is provided on the worktable 2. The third linear drive device 66 is used to drive the base plate 61 to reciprocate between the feeding components 31, the first placement platform 41, and the second placement platform 51. The third linear drive device 66 drives the base plate 61 to slide along the X direction. A pair of clamping components 65 align with and simultaneously clamp the powder metallurgy spindle 1 on the feeding assembly 31 and the first placement table 41, respectively. After the pair of clamping components 65 have clamped the spindle, the second linear drive device 64 is activated, and the mounting plate 62 rises axially along the guide post 63, causing the pair of powder metallurgy spindles 1 to disengage from the feeding assembly 31 and the first placement table 41, respectively. Then, the base plate 61 slides along the X direction, positioning the clamping component 65 that clamped the powder metallurgy spindle 1 on the feeding assembly 31 above the first placement table 41, and the other clamping component 65 above the second placement table 51. Next, the mounting plate 62 descends, and the pair of clamping components 65 open and reset, placing the powder metallurgy spindle 1 on the corresponding first placement table 41 and second placement table 51. The mounting plate 62 then rises, completing the material transfer. By utilizing the matching design between the spacing of the pair of clamping components 65 and the spacing between the workstations, the "material picking and unloading" is achieved. Parallel operation reduces idle time and improves transfer efficiency; guide column 63 ensures stable lifting of mounting plate 62; through the coordinated control of third linear drive device 66 and second linear drive device 64, fully automatic cyclic operation of material conveying module 6 is achieved without manual intervention, suitable for mass production. Base plate 61 is mounted on worktable 2 via slide rail 67. Both second linear drive device 64 and third linear drive device 66 use cylinders, and clamping component 65 uses cylinder grippers.

[0036] In this embodiment, as Figure 5As shown, the clamping component 65 includes a pair of grippers 651, each of which has an anti-slip wear layer 652 between it and the powder metallurgy shaft 1. The anti-slip wear layer 652 prevents slippage or damage when the grippers 651 clamp the powder metallurgy shaft 1, ensuring a secure grip without detachment. Furthermore, the design of the anti-slip wear layer 652 prevents the grippers 651 from directly scratching the surface of the powder metallurgy shaft 1. The anti-slip wear layer 652 is made of rubber and is detachably mounted on the grippers 651 using screws.

[0037] In this embodiment, the first placement stage 41 is provided with a receiving groove 410 adapted to the powder metallurgy rotating shaft 1. The receiving groove 410 is used to accommodate the powder metallurgy rotating shaft 1. The receiving groove 410 is used to limit the position of the powder metallurgy rotating shaft 1 placed on the first placement stage 41, so as to prevent the powder metallurgy rotating shaft 1 from undergoing radial displacement during the shaping process.

[0038] In this embodiment, as Figure 4 As shown, the shaping station 4 further includes: a second mounting frame 43 and a driving device 44. The second mounting frame 43 is disposed on the worktable 2, and the driving device 44 is mounted on the second mounting frame 43. The driving end of the driving device 44 is connected to the pressure seat 42. An elastic element 422 is provided in the receiving cavity 420. The two ends of the elastic element 422 are respectively connected to the pressure seat 42 and the pressure block 421. When the driving device 44 is started, the pressure seat 42 moves downward. The pressure block 421 first abuts against the upper end of the powder metallurgy shaft 1. The elastic element 422 will be compressed as the pressure seat 42 continues to move downward, avoiding rigid pressure that could cause the upper end of the powder metallurgy shaft 1 to break. During the upward movement of the pressure seat 42, the elastic element 422 begins to reset, pushing the pressure block 421 to squeeze the powder metallurgy shaft 1 out of the receiving cavity 420, ensuring that the powder metallurgy shaft 1 can be smoothly removed from the receiving cavity 420, and avoiding jamming that could affect the efficiency of the next shaping operation. The drive unit 44 is a cylinder, and the elastic element 422 is a spring.

[0039] In this embodiment, the detection station 5 further includes a third mounting frame 53 and a moving module 54. The third mounting frame 53 is disposed on the second placement platform 51, and the moving module 54 is disposed on the third mounting frame 53. The vision sensor 52 is mounted on the third mounting frame 53, and the moving module 54 is used to adjust the movement of the vision sensor 52 in the X-direction and vertical direction. The moving module 54 is used to adjust the movement of the vision sensor 52 in the X-direction and vertical direction to adapt to powder metallurgy rotating shafts 1 of different lengths, ensuring that the vision sensor 52 can be accurately aligned with the powder metallurgy rotating shaft 1. The shooting distance is adjusted according to the diameter or height of the powder metallurgy rotating shaft 1 to ensure the image clarity of the vision sensor 52. The moving module 54 can be a combination of a cylinder and a track. The track is mounted on the third mounting frame 53, and the cylinder is slidably mounted on the track. The movable end of the cylinder is connected to the vision sensor 52. In other embodiments, the moving module 54 can be a robotic arm.

[0040] In this embodiment, the material transfer component 7 includes a turntable 71 and a clamping component 72. The turntable 71 is rotatably adjustable on the worktable 2. A fourth linear drive device 73 is provided on the turntable 71. The clamping component 72 is installed on the movable end of the fourth linear drive device 73. The unloading component 32 includes a conveyor belt 321 and a defective product box 322. The conveyor belt 321 and the defective product box 322 are used to collect qualified powder metallurgy spindles 1 and unqualified powder metallurgy spindles 1, respectively. After the vision sensor 52 completes the shape detection of the powder metallurgy spindle 1, the turntable 71 rotates to a preset angle, aligning the clamping assembly 72 with the powder metallurgy spindle 1 on the second placement table 51. The fourth linear drive device 73 drives the clamping assembly 72 to extend and clamp the powder metallurgy spindle 1. After clamping, the fourth linear drive device 73 drives the clamping assembly 72 to retract and reset. When the powder metallurgy spindle 1 is qualified, the turntable 71 rotates to the angle corresponding to the unloading assembly 32, and the fourth linear drive device 73 drives the clamping assembly 72 to extend and place the qualified powder metallurgy spindle 1 on the unloading assembly 32. When the powder metallurgy spindle 1 is unqualified, the turntable 71 rotates to the angle corresponding to the defective box 322, and the fourth linear drive device 73 drives the clamping assembly 72 to extend and release the unqualified powder metallurgy spindle 1. Then the clamping assembly 72 resets. After completing one transfer, the turntable 71 rotates back to the initial position, waiting for the next powder metallurgy spindle 1 to be inspected. The above steps are repeated to achieve continuous transfer operation. The turntable 71 is rotatably mounted on the worktable 2 via a servo motor (not shown), the clamping assembly 72 is a cylinder gripper, and the fourth linear drive device 73 is a cylinder; in other embodiments, the material transfer assembly 7 can be a robotic arm.
