Description

Technical Field

[0001] This invention relates to the field of machining hole technology, and specifically to a machining table for machining holes in gear bushings. Background Technology

[0002] Turning is a process that uses a cutting tool rotating on a lathe spindle to cut away metal from the surface of a workpiece, thereby forming a cylindrical hole. Turning is suitable for cases with larger hole diameters, and can typically process holes with diameters ranging from 20mm to 300mm. Its advantages are fast processing speed, high processing efficiency, and low surface roughness, which can ensure the accuracy and quality of the hole.

[0003] Gear bushings are typically installed on gear shafts as external components, primarily serving to protect the shaft and support rotating parts. They reduce friction between the shaft and stationary components, thereby extending the shaft's service life. Due to their protective function, they require high precision in the bore diameter. Therefore, in actual production, compared to the traditional method of turning holes on a line-following displacement machine, the bushing structure needs to be fixed on the machining table before the hole is turned. At the same time, a robotic arm is used to clamp and transport the bushing for loading and unloading. The entire machining line not only has high requirements for the robotic arm's CCD recognition and grasping, but also, because the robotic arm and the hole turning are both coaxial, the interval between switching from hole turning to recognition and grasping after machining is large, limiting the efficiency and automation level of the entire machining line. Summary of the Invention

[0004] To address the aforementioned technical problems in the existing technology, a turning table for machining gear bushings is provided to solve the problem of the lack of a highly automated and efficient conveying and loading line for machining gear bushings.

The storage base is provided with a rail frame, and a vertical shaft with a T-shaped cross-section is inserted between the telescopic post and the rail frame. The vertical shaft and the rail frame are slidably engaged. Each corner of the rail frame is provided with a push shaft cylinder that docks with the adjacent vertical shaft. The push shaft cylinder pushes the vertical shaft by pushing the push shaft that extends into the rail frame.

[0008] The connection end between the storage seat and the transport platform has a reserved empty bushing template movable position, and a switch seat is provided in the movable position. The switch seat and the vertical shaft T-shaped surface are axially matched with a lifting arm, and the lifting arm is braked by an external lifting cylinder.

[0009] The transition platform and the storage seat have axially aligned column grooves in their empty movable positions. The transition platform is provided with connected electromagnetic heads and traction components at both ends near the storage seat and the machine hole platform. There are two electromagnetic heads in total, which are symmetrically arranged laterally on the inner side of the transition platform. The traction component is provided with a clamping head with reverse linkage at the opposite end of the electromagnetic head.

[0010] The machine hole platform is axially provided with a shaft member that matches the gear bushing, and the shaft member passes through the transition plate. The shaft member is screwed with a bushing frame and a screw member in sequence.

[0011] A bracket is fixed under the machine hole platform, and an obliquely oriented slide is provided through the bracket. A folding plate is hinged to one end of the slide near the machine hole platform.

The two ends of the I-shaped kit are respectively engaged with the adapter plate and the machining cylinder, and a spring ring is sleeved on the outer side of the I-shaped kit.

[0016] A further preferred embodiment: the cleaning table extends outward with a circular platform plate, and a baffle is attached to one end of the transition plate near the shaft member, with a clearance groove that allows for axial movement between the baffle and the shaft member and communicates with the cleaning table platform plate.

[0017] A further preferred embodiment: a liquid pipe is sleeved on the outer side of the machine hole platform, and the liquid pipe extends towards the end of the shaft member with a corrugated pipe whose shape can be freely adjusted.

The screw sleeve extends to the end of the semi-circular block and has a linked slider assembly, and the semi-circular blocks and the slider assembly are in sliding engagement.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This type of gear bushing machining table features in-line conveying, machining, and loading lines. The bushings to be machined are automatically transported along the line via arrayed storage seats and bushing templates. The bushings are then moved onto the shaft members via a transfer table, where they are assembled using telescopic shaft members. After machining, the bushings are transported via a slide under the transfer table. The entire machining process is completed automatically along the line. The coaxially telescopic shaft members simultaneously perform bushing fixing and unloading operations. Compared to traditional robotic arm clamping and conveying methods, this approach simplifies automation steps while ensuring conveying and loading accuracy, thus improving the overall machining efficiency and automation level of gear bushing machining.

Detailed Implementation

[0032] Please see Figure 1-8 The embodiments of the present invention will be further described below;

[0033] A machining table for gear bushings includes a storage seat 1, a machining table base 2, and a transition plate 3, which are connected in sequence.

[0034] The storage base 1 is provided with multiple bushing templates 4, which are arranged in an array. A positioning post 5 is provided through the bushing template 4. A telescopic post 18 is slidably provided in the positioning post 5. The positioning post 5 and the telescopic post 18 form a stepped surface for the gear bushing to be inserted. The storage base 1 is provided with a rail frame 13. A vertical shaft 14 with a T-shaped cross section is inserted between the telescopic post 18 and the rail frame 13. The vertical shaft 14 and the rail frame 13 are slidably engaged. Each corner of the rail frame 13 is provided with a push shaft cylinder 11 that is engaged with the adjacent vertical shaft 14. The push shaft cylinder 11 pushes the vertical shaft 14 by pushing the push shaft 17 that extends into the rail frame 13.

[0035] The connection end between the storage seat 1 and the transport table 2 has a reserved empty bushing template 4 movable position, and a switch seat 12 is provided in the movable position. The switch seat 12 and the vertical shaft 14 T-shaped surface are axially matched with a lifting arm 16, which is braked by an external lifting cylinder 15.

[0036] The transition plate 3 and the storage seat 1 have axially aligned column grooves 6 in their empty movable positions. The transition plate 3 is provided with connected electromagnetic heads 23 and traction components 24 at both ends near the storage seat 1 and the machine hole platform 2, respectively. There are two electromagnetic heads 23 arranged symmetrically on the inner side of the transition plate 3, and the traction components 24 are provided with reverse linkage clamping heads 25 at the opposite ends of the electromagnetic heads 23.

[0037] A shaft member 8 matching the gear bushing is axially arranged on the machining platform 2, and the shaft member 8 passes through the transition plate 3. The shaft member 8 is screwed with a bushing bracket 30 and a screw member 29 in sequence.

[0038] A bracket 19 is fixed under the machine hole platform 2. A sliding table 27 is provided through the bracket 19 at an angle, and a folding plate 22 is hinged to one end of the sliding table 27 near the machine hole platform 2.

[0039] This type of machining platform for gear bushings has a horizontally arranged storage seat 1, machining platform 2, and transfer plate 3 forming a gear bushing loading and processing line. The storage seat 1 serves as the loading platform for the bushing template 4. Under the push of the push cylinder 11 and push shaft 17, the vertical shaft 14 inside the bushing template 4 moves with the rail frame 13. The array of bushing templates 4 can be arranged in a specific number and specification according to the actual processing situation. The rail frame 13 changes synchronously according to the arrangement specification of the bushing template 4 to cope with the loading of the entire plate of gear bushings under different processing quantities.

[0040] The movable position of the bushing template 4 controlled on the placement seat 1 is reserved for the bushing template 4 before and after loading and moved to the conveying position, so that the sequential push shaft 17 pushes and changes the relative position of the bushing template 4 on the placement seat 1. Before the bushing template 4 moves to the column groove 6 position, the horizontally displaced bushing template 4 will automatically align and match the internal vertical shaft 14 with the lifting arm 16, and drive the lifting arm 16 to rise through the axial feed of the lifting cylinder 15. Thus, the displacement of the lifting arm 16 causes the vertical shaft 14 and the positioning column 5 and telescopic column 18 connected to the vertical shaft 14 to rise, so that the bushing to be processed passes through the column groove 6 and enters the horizontal plane of the transfer table 3. The bushing is attracted and secured by the energization of the electromagnetic head 23, and then the positioning column 5 is moved down by the feed and descent of the lifting cylinder 15. During the process, the vertical shaft 14 is pulled down by the movement of the lifting arm 6 with a relatively small stroke, thereby releasing the stepped surface formed by the telescopic column 18 and the positioning column 5, which facilitates the subsequent separation and horizontal movement of the bushing. After the transfer, the vertical shaft 14 and the traction arm 16 are reset to deal with subsequent operations. The unloading and unloading operation of the entire gear bushing and bushing template 4 avoids the use of mechanical arm clamping and conveying while ensuring the conveying accuracy. The overall integration of the processing and conveying line is high, avoiding the problem of improper clamping interfering with the conveying efficiency.

[0041] The transfer platform 3 structure mainly achieves the translational transport of the storage seat 1 to the machine hole platform 2 by using the electromagnetic head 23, which is braked by the traction component 24. Meanwhile, its two ends... Figure 5 As shown, the two ends of the adapter plate 3 converge from the wide diameter end of the placement seat 1 to the narrow diameter end of the machine hole platform 2. The side rail structure of the adapter plate 3 also serves to guide and straighten the gear bushing, so as to improve the matching accuracy of the gear bushing moving to the axial position of the shaft member 8.

[0042] The machining platform 2 uses a telescopic bushing bracket 30 to fix the shaft member 8. Before the gear bushing is displaced to the axial position of the shaft member 8 on the transfer platform 3, the position of the shaft member 8 is controlled by the spiral feed of the servo motor 28 and the screw member 29. After moving to the position of the shaft member 8 with the gear bushing, the rising shaft member 8 aligns with the gear bushing and performs subsequent machining. After machining, the shaft member 8 is released from positioning with the gear bushing by telescopic reset, and the traction component 24 drives the clamping head 25 to slide the gear bushing into the position of the folding plate 22 on the transfer platform 3 by the reset movement of the folding plate 22. The passage with the slide table 27 is opened by the hinge movement of the folding plate 22, and finally the gear bushing is output to the subsequent line through the slide table 27. The entire positioning, loading and unloading, and conveying process before and after machining is arranged along the line, avoiding the difficulty of installation and arrangement and the limitations of positioning effect and positioning speed when using a robotic arm for clamping, effectively improving the automation level and processing efficiency of the overall machining.

[0043] The pushing stroke of the push shaft 17 and the push shaft cylinder 11 is consistent with the distance between the vertical shaft 14, so as to ensure that the feeding accuracy of the push shaft 17 and the push shaft cylinder 11 matches the distance between the adjacent bushing template 4, and to ensure the displacement accuracy of the bushing template 4 on the placement seat 1.

[0044] Based on the above, the storage seat 1 and the bushing template 4 are freely arranged and combined by inserting and matching the vertical shaft 14. The bushing template 4 is positioned on the vertical shaft 14 by inserting and loading, which makes it convenient to freely load and unload the bushing template 4 and the storage seat 1 according to the modular bushing template 4. The entire plate of gear bushing is transported by transferring the bushing template 4.

[0045] The lifting arm 16 has a clamping structure, and a clamping opening is formed in the lifting arm 16 for the vertical shaft 14 to pass through laterally, such as... Figure 3 As shown, the clamping lifting arm 16 structure mainly uses the concave clamping end to match the axial displacement with the vertical shaft 14. At the same time, the opening allows the bushing template 4 to be accurately positioned with the lifting arm 16 through the laterally moving vertical shaft 14 when it is displaced.

[0046] A machining cylinder 20 is provided on the outer side of the connection end between the adapter plate 3 and the shaft member 8. A cleaning table 21 is fixed between the machining cylinder 20 and the adapter plate 3. A I-shaped kit 26 is embedded in the sleeve 21. The two ends of the I-shaped kit 26 are respectively engaged with the adapter plate 3 and the machining cylinder 20. A spring ring is sleeved on the outer side of the I-shaped kit 26. The two ends of the bridged adapter plate 3 are respectively connected to the cleaning table 21 through the bracket 19 structure to strengthen the connection between the two ends of the adapter plate 3. The structure also uses the axially arranged I-shaped kit 26 to cooperate with the machining cylinder 20 to improve the strength of the entire axial structure of the shaft member 8 and the bushing frame 30. The spring ring and the I-shaped kit 26 are used to reduce the impact of the machining cylinder 20 to the adapter plate 8 during hole machining.

[0047] Based on the above, the cleaning table 21 extends outward with a circular platform plate. A baffle 7 is attached to one end of the transfer table 3 near the shaft member 8. A gap groove with a margin between the baffle 7 and the axial movement space of the shaft member 8 and communicating with the platform plate of the cleaning table 21 is provided. Due to the continuous and uninterrupted falling characteristics of the cutting chips generated by the machining, the circular platform plate on the cleaning table 21 and the gap groove communicating with the transfer table 3 serve as a chip collection platform. The baffle 7 is used to prevent the chips from non-continuous segments from splashing onto the transfer table 3.

[0048] A liquid pipe 9 is sleeved on the outer side of the machining platform 2, and a bellows 10 with an adjustable tube shape extends from the liquid pipe 9 to the end of the shaft member 9. Compressed foam liquid is used as the cleaning medium. The shaft sleeve is rinsed after machining by adjusting the position of the nozzle of the bellows 10, and the aforementioned cleaning platform 21 is used to isolate and collect machining debris.

[0049] The traction component 24 is an electric spiral winding mechanism. The winding width of the traction component 24 has a minimum 2cm empty winding range. The spiral winding traction component 24 can increase the horizontal winding amplitude of the traction component 24 within a small arrangement range by rotating the extension structure at both ends of the winding towards the electromagnetic head 23. At the same time, the reserved empty winding range ensures that the tension difference of the connection structure between the electromagnetic head 23 and the traction component 24 does not affect the traction distance. That is, it ensures that when the traction component 24 is wound to the limit position, the electromagnetic head 23 can push the gear bushing to the designated position.

[0050] The clamping head 25 is an electromagnetic component for power-on switching. The sliding distance of the clamping head 25 is slightly larger than the radius of the shaft member 8. The connection with the gear bushing is switched by energizing the electromagnetic head and switching the electromagnetic switch, so as to improve the connection strength between the clamping head 25 and the gear bushing. That is, it is ensured that when the clamping head 25 moves to the limit position, it can bring the gear bushing into the slide opening on the slide table 27, ensuring the smoothness of the entire conveying line.

[0051] The shaft member 8 is composed of three equally spaced semi-circular blocks, and a screw sleeve 31 is spirally arranged at the core between the three semi-circular blocks. The screw sleeve 31 extends to the end of the semi-circular block and a linked slider assembly 32. The semi-circular blocks and the slider assembly 32 are in sliding engagement. Compared with the method of selecting the corresponding shaft member 8 specification according to the diameter of the gear bushing to be processed, the diameter of the shaft member 8 can be changed by rotating the screw sleeve 31 before processing to drive the slider assembly 32 to push away from the semi-circular block, thereby adapting to the different machining requirements of the gear bushing.

[0052] Working principle:

[0053] 1) Arrange the corresponding number of bushings to be processed by the bushing template 4. The bushings to be processed, together with the bushing template 4, can be loaded into the vertical shaft 4 on the storage seat 1 by the whole plate conveying method for subsequent conveying.

[0054] 2) During operation, the push-shaft cylinders 11 at each corner of the rail frame 13 are braked, and the push-shaft 17 is used to sequentially push the vertical shaft 14 and the bushing template 4 at the designated positions, so that the array position of the bushing template 4 changes. When the bushing template moves to the column groove 6, the lifting cylinder 15 is braked, and the lifting arm 16 and the vertical shaft 14 are used to lift the positioning column 5 and the telescopic column 18 to raise the bushing into the horizontal surface of the transfer platform 3. During this period, the electromagnetic head 23 is energized to hold the bushing in place. In the subsequent resetting process of the lifting cylinder 15, the cooperation between the lifting arm 6 and the section of the vertical shaft 14 is used to release the stepped surface of the telescopic column 18 and the positioning column 5.

[0055] 3) After braking by the traction component 24, the electromagnetic head 23 will push the bushing from one end of the transfer table 3 to the other end. After the displacement reaches the designated position, the synchronous feed of the servo motor 28 will be used to screw the screw 29 and the bushing bracket 30, so that the shaft 8 on the bushing bracket 30 passes through the transfer table 3 and is docked and fixed with the bushing, so as to carry out subsequent hole machining.

[0056] 4) During the machining process, compressed foam medium is conveyed through liquid pipe 9 and bellows 10 to flush the machined hole of the bushing;

[0057] 5) After the machining of the bore is completed, the servo motor 28 is reset to disconnect the shaft 9 from the gear bushing. Then, the traction assembly 24 is reset simultaneously to allow the clamping head 25 to absorb and hold the gear bushing and return with the transfer table 3. During the process, the gear bushing is slid into the slide table 27 by controlling the opening of the folding plate 22 and is transported to the subsequent processing line to complete the entire gear bushing transport and processing.
