Description

Technical Field

[0001] This utility model relates to the technical field of gear shaping equipment, specifically a workpiece conveying device for a gear shaping machine. Background Technology

[0002] As a key component in mechanical transmission systems, driven gears typically require precision correction of their tooth profile, center hole, and outer circle contour using specialized forming equipment after the blank is formed. This is done to improve assembly accuracy, meshing stability, and transmission efficiency, ensuring good concentricity, low noise, and operational balance under high load conditions.

[0003] The shaping process relies on a gear shaping machine to complete the press forming. However, in the existing gear shaping production line, the feeding, loading and unloading of driven gears are mostly done manually.

[0004] Specifically, multiple sets of gear blanks are stacked in a material box and transported to the side of the forming machine by forklift or manual labor. Then, the operators take them out one by one and manually place them in the forming station. After the forming is completed, the finished gears are taken out manually and transferred to the subsequent process.

[0005] While the above methods have low equipment investment costs, they have the following drawbacks in actual operation:

[0006] First, because the material is supplied by a hopper, it takes a long time for workers to pick up the materials. Frequent manual loading and unloading can easily create a bottleneck, making it difficult to meet the production pace of medium and high speeds, resulting in low production efficiency.

[0007] Secondly, gears are prone to collisions during handling, placement, and transfer, which affects the yield of manufactured parts.

[0008] Third, high-intensity repetitive operations not only increase the workload of workers, but also bring higher risks of misoperation and workplace injuries. In addition, the manual loading and unloading processes are highly dependent on the skills of the operators.

[0009] Therefore, in order to solve the above problems, there is an urgent need to provide a compact and efficient workpiece conveying device for gear shaping machines. Summary of the Invention

[0010] This utility model addresses the shortcomings of existing technologies by proposing a workpiece conveying device for a gear shaping machine. The specific technical solution is as follows:

[0011] A workpiece conveying device for a gear shaping machine, characterized in that:

[0012] It includes a quantitative feeding mechanism, a feeding and gripping mechanism, a shaping table, a transverse pushing assembly, a longitudinal pushing assembly, a transverse and longitudinal sliding table, and a guiding assembly;

[0013] The quantitative feeding mechanism includes a frame, a transmission disk, a drive motor, stacking components, and a lifting mechanism. The transmission disk is rotatably connected to the frame, and the drive motor is used to drive the transmission disk to rotate. Multiple stacking components are evenly arranged along the circumference of the transmission disk.

[0014] The stacking assembly includes a chassis, a guide shaft, and a first lifting plate. The lower end of the guide shaft is fixedly connected to the middle of the chassis, and the first lifting plate is mounted on the guide shaft in a sliding sleeve.

[0015] The feeding and gripping mechanism is located above the feeding area of ​​the quantitative feeding mechanism and is used to grip the gears conveyed by the stacking assembly.

[0016] The transverse pushing component, the longitudinal pushing component, and the transverse and longitudinal sliding stage are all disposed at the feeding end of the forming table. The transverse and longitudinal sliding stage is disposed opposite to the longitudinal pushing component, and the transverse pushing component is located between the longitudinal pushing component and the transverse and longitudinal sliding stage.

[0017] The guide assembly is fixedly connected to the adjustment part of the horizontal and vertical sliding table;

[0018] The transverse pushing assembly is used to push the gear between the longitudinal pushing assembly and the transverse and longitudinal sliding table. The longitudinal pushing assembly is used to guide the gear into the limiting groove of the guide assembly. The transverse and longitudinal sliding table is used to transfer the gear to the shaping station.

[0019] To better realize this utility model, the guide component may further include a vertical plate and a horizontal plate;

[0020] The vertical plate is connected to the adjusting part, and the inner side of the horizontal plate is fixedly connected to the lower end of the vertical plate.

[0021] The outer side of the horizontal plate has an arc-shaped groove that matches the outer periphery of the gear, forming a limiting groove for the guide assembly.

[0022] Furthermore: the chassis is provided with a set of first through holes, and the transmission disk is provided with a set of second through holes corresponding to the first through holes;

[0023] When the stacking assembly rotates to the feeding area with the transmission disk, the lifting part of the lifting mechanism passes through the second through hole and the first through hole in sequence, and pushes the first lifting plate to move upward along the guide axis.

[0024] Furthermore: the lifting mechanism includes a base, a top plate, a lead screw, a second lifting plate, a guide rod, and a top rod;

[0025] The upper end of the lead screw is rotatably connected to the top plate, and the lower end is rotatably connected to the base.

[0026] Three guide rods are provided between the top plate and the base. The second lifting plate is slidably installed on the three guide rods and threadedly connected to the lead screw.

[0027] The three top rods are evenly arranged on the upper surface of the second lifting plate.

[0028] Furthermore: the feeding and gripping mechanism includes a feeding bracket, a linear module, a gripping bracket, and grippers;

[0029] The lower end of the feeding bracket is fixedly installed on the frame, the linear module is disposed on the feeding bracket, the gripping bracket is installed on the moving end of the linear module, and the gripper is installed on the lower end of the gripping bracket for gripping the lifting gear in the stacking assembly.

[0030] Furthermore: the material discharge end of the shaping table is provided with two limiting guide rails, which are arranged side by side;

[0031] The two limiting guide rails form a guide channel for the movement of the guide gear, and the end of the guide channel is connected to the feed port of the feeding chute.

[0032] Furthermore, a receiving device is provided near the discharge end of the shaping table, and a feeding gripping mechanism is provided between the shaping table and the receiving device to grip the shaped gear from the shaping table and transfer it to the receiving device.

[0033] The beneficial effects of this utility model are as follows:

[0034] First, by setting up a quantitative feeding mechanism, multiple gears can be stored and fed in an orderly manner. The transmission plate can be automatically positioned by relying on the induction trigger and proximity switch. The lifting mechanism, together with the top rod structure, can accurately lift the stacked gears, avoiding the high labor intensity of feeding in traditional manual material handling.

[0035] Secondly, separate feeding and unloading mechanisms are set up to complete the material handling of stacked gears and the transfer of finished gears, respectively, thereby improving the level of automation.

[0036] Third, a receiving device is provided. This device has the same structure as the quantitative feeding mechanism. By cooperating with the feeding and gripping mechanism, the shaped gears are collected in an orderly manner, realizing the automation of the discharge process. This facilitates subsequent unified handling and sorting, and avoids the collision problems caused by disorderly stacking in the traditional discharge process.

[0037] Fourth, by setting up a transverse pushing component, a longitudinal pushing component, a transverse and longitudinal sliding stage and a guide component at the feeding end of the forming table, a complete feeding guidance and station feeding structure is formed, which can realize the precise conveying process of gears completed by multiple components working together before forming, effectively replacing the traditional manual placement method and avoiding work-related accidents.

[0049] like Figures 1 to 8 As shown:

[0050] In this embodiment, the direction from the feed end to the discharge end of the gear press machine is defined as the transverse direction, and the direction perpendicular to it is defined as the longitudinal direction. The shaping station is set in the middle of the shaping table and is used for the precision pressing and shaping of the gear.

[0051] The shaping station includes an upper pressure table located above the shaping table and a lower base table located below the shaping table.

[0052] The upper pressure table is a pressing structure that can move up and down in the longitudinal direction. It is used to center the gear and apply downward pressing force during the forming process. The upper pressure table is not a standard component and is not shown in the figure.

[0053] The lower platform is supported by a vertical lifting mechanism. The top of the lower platform is equipped with a limiting platform, which is used to support the gear to be shaped in an upward state before shaping. During the shaping process, it sinks down to cooperate with the upper pressure table to complete the gear shaping operation.

[0054] The aforementioned upper pressure platform and lower base platform are standard structural components in existing gear shaping mechanisms, and in this embodiment, they serve as shaping stations to complete gear meshing shaping.

[0055] A workpiece conveying device for a gear shaping machine includes a quantitative feeding mechanism 1, a feeding gripping mechanism 2, a shaping table 3, a transverse pushing assembly 30, a longitudinal pushing assembly 31, a transverse and longitudinal sliding table 32, a guiding assembly 33, a discharging gripping mechanism 4, and a receiving device 5.

[0056] The quantitative feeding mechanism 1 is located on the feeding side of the shaping table 3. The quantitative feeding mechanism 1 includes a frame 6, a drive motor, a transmission disk 8, a rotating shaft 9, a stacking assembly 10, and a lifting mechanism 11.

[0057] The rotating shaft 9 is vertically arranged and rotatably connected to the middle of the platform of the frame 6 through a bearing assembly. The transmission disk 8 is fixedly connected to the upper end of the rotating shaft 9 and rotates with it.

[0058] The first drive motor 7 is installed inside the frame 6. The first drive motor 7 is connected to the lower end of the rotating shaft 9 through a coupling to drive the transmission disk 8 to rotate.

[0059] The transmission disk 8 has a circular structure. Multiple mounting holes for fixing the stacked components 10 are evenly distributed on the outer periphery of the transmission disk 8. Several universal conveying balls 29 are also provided on the lower outer edge of the transmission disk 8 to support its weight.

[0060] Multiple stacked components 10 are evenly arranged circumferentially along the drive disk 8.

[0061] Each stacking assembly 10 includes a chassis 12, a guide shaft 13, and a first lifting plate 14. The guide shaft 13 is vertically arranged in the middle of the chassis 12 and is used to pass through the gear to be processed. Multiple gears are stacked sequentially on the first lifting plate 14.

[0062] The first lifting plate 14 has a ring structure with a sliding guide hole in the middle to fit onto the guide shaft 13 and achieve vertical sliding along the guide shaft 13.

[0063] The chassis 12 is provided with a first through hole 15, and the transmission disc 8 is provided with a corresponding second through hole 16. When the two are assembled, they are aligned accordingly, so that the top rod 22 of the lifting mechanism 11 passes through and lifts the first lifting plate 14.

[0064] The lifting mechanism 11 is located below the feeding area and includes a base 17, a top plate 18, a lead screw 19, a second lifting plate 20, a guide rod 21, and a top rod 22.

[0065] The base 17 is fixedly installed inside the frame 6, and the top plate 18 is connected above the base 17 by three guide rods 21 and kept horizontal.

[0066] The upper end of the lead screw 19 is rotatably connected to the top plate 18 via a thrust bearing assembly, and the lower end is rotatably connected to the base 17 via a cylindrical bearing.

[0067] The second lifting plate 20 is sleeved on the guide rod 21 through three guide holes and is threadedly connected to the lead screw 19 in the middle.

[0068] The lower end of the lead screw 19 is fixedly fitted with a driven pulley 23, and the bottom of the base 17 is equipped with a driving pulley 24 that cooperates with it. A synchronous transmission belt 25 is provided between the two.

[0069] The second drive motor 26 drives the active pulley 24 to rotate, thereby driving the lead screw 19 to rotate, realizing the lifting and lowering of the second lifting plate 20.

[0070] Three push rods 22 are evenly distributed at an angle of ° on the second lifting plate 20. The push rods 22 are the lifting parts of the lifting mechanism 11. The upper end of the push rods 22 pushes the first lifting plate 14 upward along the guide shaft 13 by pushing into a set position on the lower surface of the first lifting plate 14.

[0071] The frame 6 is located on the side adjacent to the forming table 3, and the feeding area is provided. The feeding gripping mechanism 2 is located above the feeding area.

[0072] The feeding area is equipped with a proximity switch sensor 27, which is fixedly installed on the frame 6.

[0073] Near each stacked assembly 10, a sensing trigger is provided on the outer periphery edge of the transmission disk 8. The sensing trigger is fixed to the outer circumference edge of the transmission disk 8 with bolts 28, and each sensing trigger corresponds to a specific stacked assembly 10.

[0074] When the drive disk 8 rotates to the feeding area, the sensing trigger enters the detection area of ​​the proximity switch sensor 27. The sensor outputs an electrical signal, which the control system receives and causes the drive motor to stop running, and the drive disk 8 to stop rotating, thereby achieving precise positioning of the stacked assembly 10 in the feeding area.

[0075] The feeding and gripping mechanism 2 includes a feeding bracket 42, a linear module 43, a gripping bracket 44, and a gripper 45.

[0076] The lower end of the feeding bracket 42 is fixedly installed on the frame 6. The linear module 43 adopts the linear sliding module in the prior art and is used to drive the gripping bracket 44 to move horizontally.

[0077] The gripping bracket 44 is installed on the moving end of the linear module 43, and the gripper 45 is fixed on the lower end of the gripping bracket 44. An existing electric gripper 45 can be used to grip the gear that is lifted by the lifting mechanism 11 in the stacked assembly 10 and transfer it to the feeding end of the shaping table 3.

[0078] The feeding end of the shaping table 3 is provided with a transverse pushing component 30, a longitudinal pushing component 31, and a transverse and longitudinal sliding table 32. The transverse pushing component 30 is located between the longitudinal pushing component 31 and the transverse and longitudinal sliding table 32, and the transverse and longitudinal sliding table 32 is arranged opposite to the longitudinal pushing component 31.

[0079] The transverse pusher assembly 30 is used to push the gear into the position between the longitudinal pusher assembly 31 and the transverse and longitudinal sliding table 32.

[0080] The pushing end of the transverse pushing component 30 is connected to a push block 38. The transverse pushing component 30 adopts a driving cylinder. The outer side of the push block 38 is provided with a V-shaped opening that matches the outer circle of the gear, which is used to limit the gear posture.

[0081] The longitudinal pusher assembly 31 has the same structure as the transverse pusher assembly 30, and is also provided with a pusher block 38 for guiding the gear into the limiting groove of the guide assembly 33.

[0082] The guide assembly 33 is fixedly installed on the adjustment part of the horizontal and vertical sliding table 32. The guide assembly 33 includes a vertical plate 35 and a horizontal plate 36. The vertical plate 35 is connected to the adjustment part of the horizontal and vertical sliding table 32. The inner side of the horizontal plate 36 is fixed to the lower end of the vertical plate 35. An arc-shaped limiting groove adapted to the outer periphery of the gear is opened on the outer side of the horizontal plate 36.

[0083] The transverse and longitudinal sliding stage 32 is a dual-axis sliding module structure, installed at the feeding end of the forming stage 3, and is used to drive the guide assembly 33 to slide along the transverse and longitudinal directions, thereby sending the gear from the inlet position to the forming station.

[0084] The material discharge end of the shaping table 3 is equipped with a limiting guide rail 39. Two limiting guide rails 39 are arranged side by side to form a guide channel 40. The end of the guide channel 40 is connected to the feed port of the unloading chute 46 to guide the shaped gear into the unloading area.

[0085] A feeding gripping mechanism 4 is provided between the shaping table 3 and the receiving device 5, which is used to grip the shaped gear from the shaping station and transfer it to the receiving device 5. The feeding gripping mechanism 4 is structurally the same as the feeding gripping mechanism 2, and is installed symmetrically on the discharge end of the other side of the shaping table 3.

[0086] The receiving device 5 is a stacked assembly 10 structure with the same structure as the quantitative feeding mechanism 1. The receiving device 5 is used to stack and receive the gears after they have been shaped.

[0087] The principle of this utility model:

[0088] During operation, multiple stacked components 10 are evenly distributed circumferentially along the transmission disk 8 and rotate synchronously around the central axis with the transmission disk 8. When the transmission disk 8 is driven by the drive motor, each stacked component 10 enters the feeding area in sequence. The feeding area is equipped with a proximity switch sensor 27, which is used to detect the induction trigger fixed on the outer periphery of the transmission disk 8. When a certain induction trigger enters the sensing range of the sensor as the transmission disk 8 rotates, the sensor outputs a detection signal to the control system. The control system then controls the drive motor to stop running, thereby stopping the transmission disk 8 at the predetermined feeding position, achieving precise positioning of the current stacked component 10.

[0089] After the stacking assembly 10 is positioned, the lifting mechanism 11 is activated. The drive motor inside the lifting mechanism 11 drives the active pulley 24 to rotate, which in turn drives the driven pulley 23 to rotate via the synchronous transmission belt 25, thereby causing the lead screw 19 to rotate vertically. The lead screw 19 is threadedly connected to the second lifting plate 20, and the rotation of the lead screw 19 causes the second lifting plate 20 to rise along the vertical direction defined by the guide rod 21. The three top rods 22 set on the second lifting plate 20 are distributed at equal angles, with their upper ends aligned with the bottom of the chassis 12 of the stacking assembly 10 in the feeding area.

[0090] As the push rod 22 rises synchronously, its upper end passes through the second through hole 16 of the transmission disc 8 and the corresponding first through hole 15 on the chassis 12, and contacts the bottom of the first lifting plate 14. When the push rod 22 continues to rise, the first lifting plate 14 is lifted, which in turn pushes the remaining stacked driven gears above it upwards until the uppermost driven gear reaches the set feeding height position. At this point, the feeding gripping mechanism 2 is activated, and the gripper 45 grabs the gear and places it in front of the transverse pushing assembly 30.

[0091] At the same time, the transverse pusher assembly 30 is activated, and the pushing end of the transverse pusher assembly 30 pushes the pusher block 38 to move laterally. The V-shaped opening of the pusher block 38 pushes the driven gear to be processed to the middle position between the longitudinal pusher assembly 31 and the transverse and longitudinal sliding table 32.

[0092] Subsequently, the longitudinal pushing component 31 is activated, and the longitudinal pushing and pulling component pushes the gear in the longitudinal direction, causing it to enter the limiting groove of the guide component 33.

[0093] The guide assembly 33 consists of a vertical plate 35 and a horizontal plate 36. The outer side of the horizontal plate 36 is provided with an arc-shaped groove 37 structure that matches the outer periphery of the gear, which is used to limit the position of the gear and prevent attitude deviation.

[0094] Immediately afterwards, the horizontal and vertical sliding table 32 moves first in the horizontal direction, bringing the guide component 33 together with the driven gear to the shaping station, and then pushes the driven gear to move in the vertical direction, so that the driven gear abuts against the limiting plate 41 set in front of the shaping station.

[0095] The inner side of the limiting plate 41 is provided with multiple positioning teeth that match the gear tooth profile to prevent the driven gear from deviating.

[0096] After the positioning action is completed, the lower base 34 moves, causing the gear located in the limiting groove of the guide component 33 to sink vertically to the forming and pressing position. At this time, the horizontal and vertical sliding table 32 begins to return along the original path and brings the guide component 33 back to the initial feeding position.

[0097] As the horizontal and vertical sliding table 32 returns, the upper pressure table moves downward to press and shape the lowered gear. After shaping, the lower base 34 drives the shaped gear back to the initial plane, and the horizontal and vertical sliding table 32 performs the feeding action again to send the next gear into the shaping station.

[0098] During the movement of the guide assembly 33 carrying the next gear to the shaping station, the outer side of its horizontal plate 36 will contact the outer periphery of the gear that has been shaped in the previous processing cycle, and push the finished gear along the discharge direction to the guide channel 40 in the discharge end in the movement path.

[0099] The discharge end is equipped with two limiting guide rails 39, which are arranged side by side to form a guide channel 40 to regulate the movement trajectory of the gear. The end of the guide channel 40 is connected to the feed port of the discharge chute 46, so that the gear can smoothly enter the discharge channel and realize automatic discharge after shaping.

[0100] The feeding and gripping mechanism 4 grips the shaped gear onto the receiving device 5.

[0101] After the material is picked up, the control system controls the lifting mechanism 11 to reverse, causing the top rod 22 to descend and reset, and the first lifting plate 14 to descend to the initial position.

[0102] The control system then starts the first drive motor 7, and the transmission disc 8 continues to rotate. The next set of stacked components 10 enters the feeding area, and the above action process is repeated.

[0103] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0104] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
