Description

Technical Field

[0001] This utility model relates to the field of feeding technology for gear hobbing machines, and in particular to an auxiliary feeding mechanism and a gear hobbing machine. Background Technology

[0002] When machining shaft parts on a gear shaper, hydraulic clamps are typically used to ensure clamping rigidity. However, the clearance between the chuck and the workpiece in these clamps is relatively small. When machining large or heavy shaft parts, limitations imposed by machine tool structure, safety features, and workshop conditions mean that the workpiece cannot be directly placed into the hydraulic clamp when using a bridge crane for hoisting. Manual pulling and pushing of the workpiece is required, posing a significant safety hazard due to its elevated position. To address this issue, we propose an auxiliary feeding mechanism and a gear shaper equipped with this mechanism. Utility Model Content

[0003] The purpose of this utility model is to provide an auxiliary feeding mechanism that can place the workpiece on the feeding seat at a low position outside the gear hoist, and then move the workpiece to the upper position of the hydraulic clamp by the rising and rotating of the feeding seat. This avoids the safety hazards caused by hoisting the workpiece to a high position with lifting equipment and then manually pulling and pushing the workpiece into the hydraulic clamp.

[0004] To achieve the above objectives, this utility model provides an auxiliary feeding mechanism, including a base, a slide plate, a telescopic mechanism, and a feeding seat. The slide plate is longitudinally slidably mounted on one side of the base via a sliding mechanism. The telescopic mechanism is also mounted on the base, and the telescopic end of the telescopic mechanism is connected to the slide plate to drive the slide plate to move up and down. The feeding seat is mounted on the slide plate via a pivot hinge structure, allowing the feeding seat to swing left and right. The feeding seat is provided with a longitudinally penetrating limiting hole.

[0005] The limiting hole is provided with an annular flange, and the limiting hole forms a limiting platform on the upper side of the flange.

[0006] The top of the limiting hole is provided with a flared opening.

[0007] The feeding seat is provided with a notch, which is connected to the limiting hole.

[0008] The base includes a side plate and a support. The support is fixedly connected to the side plate. The sliding mechanism is located on the side of the side plate away from the support. A longitudinal cavity is provided inside the support. The telescopic mechanism is fixedly installed in the cavity.

[0009] The telescopic end of the telescopic mechanism extends upward, the upper end of the slide plate is fixedly connected to one end of the connecting plate, and the other end of the connecting plate extends above the cavity and is fixedly connected to the telescopic end of the telescopic mechanism.

[0010] The sliding mechanism includes linear guide rails and sliders. Two linear guide rails are installed longitudinally spaced and parallel on the base. Two sliders are installed on the slide plate at positions corresponding to the linear guide rails. The sliders are slidably connected to the linear guide rails.

[0011] The slide plate is equipped with a hinge mechanism, and the material feeding seat is mounted on the hinge mechanism. The hinge mechanism includes a first hinge plate, a second hinge plate, and a pivot. One end of the first hinge plate is provided with a slot, and one side of the second hinge plate is provided with a protrusion that is inserted into the slot. The first and second hinge plates are provided with through hinge holes at the corresponding slot and protrusion positions. The pivot is inserted into the hinge hole. The first hinge plate is mounted on the slide plate, the material feeding seat is connected to the second hinge plate, and the second hinge plate rotates around the pivot.

[0012] A transition piece is installed on the second hinge plate, and a feeding seat is installed on the transition piece; the transition piece includes a longitudinal block and a transverse block, the transverse block is fixed to the lower end of the longitudinal block, the upper end of the longitudinal block is fixed to the second hinge plate, and a clearance opening is provided on the transverse block. The feeding seat is detachably installed on the transverse block by bolts, and the clearance opening corresponds to the position of the limiting hole.

[0013] A gear hobbing machine is equipped with the aforementioned auxiliary feeding mechanism.

[0014] Compared with the prior art, this utility model has the following technical effects:

[0015] 1. The base of this utility model is fixedly installed on the base of the gear hoist. The slide plate is longitudinally slidably installed on the base through a sliding mechanism. The telescopic mechanism is used to drive the slide plate to move up and down. The unloading seat is used to place the workpiece. In use, the lower end of the workpiece passes through the limiting hole on the unloading seat, and the step on the workpiece abuts against the unloading seat. Since the unloading seat is pivotally connected to the slide plate, when the unloading seat swings to the right, the unloading seat moves away from the rotary table of the gear hoist; when the unloading seat swings to the left, the unloading seat rotates to above the hydraulic clamp; when the telescopic mechanism drives the slide plate to descend, the lifting position of the workpiece is lowered; when the telescopic mechanism drives the slide plate to descend, the workpiece is raised above the hydraulic clamp. This invention allows the workpiece to be placed on the feeding seat at a low position outside the gear hoist. Then, by raising and rotating the feeding seat, the workpiece is moved to the upper position of the hydraulic clamp. After that, the feeding seat lowers and loads the workpiece into the hydraulic clamp, thus avoiding the safety hazards caused by hoisting the workpiece to a high position with lifting equipment and then manually pulling and pushing the workpiece into the hydraulic clamp.

[0016] 2. This utility model, by setting a transition piece, facilitates reducing the lifting height of the workpiece and makes it easy to replace the material feeding seat as needed. Attached Figure Description

[0035] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0036] Example 1:

[0037] See Figure 1-2 An auxiliary feeding mechanism includes a base 10, a slide plate 30, a telescopic mechanism 40, and a feeding seat 50. The slide plate 30 is longitudinally slidably mounted on one side of the base 10 via a sliding mechanism 20. The telescopic mechanism 40 is also mounted on the base 10. The telescopic end 41 of the telescopic mechanism 40 is connected to the slide plate 30 to drive the slide plate 30 to move up and down. The feeding seat 50 is mounted on the slide plate 30 via a pivot hinge structure. The feeding seat 50 can swing left and right. The feeding seat 50 is provided with a longitudinally penetrating limiting hole 51.

[0038] The base 10 is used for fixed installation on the base of the gear hobbing machine. The slide plate 30 is longitudinally slidably installed on the base 10 via the sliding mechanism 20. The telescopic mechanism 40 is used to drive the slide plate 30 to move up and down. The feeding seat 50 is used to place the workpiece 300. In use, the lower end of the workpiece 300 passes through the limiting hole 51 on the feeding seat 50, and the step on the workpiece 300 abuts against the feeding seat 50. Since the feeding seat 50 is pivotally connected to the slide plate 30, see [reference needed]. Figure 2 When the unloading seat 50 swings to the right, it moves away from the rotary table 100 of the gear shaper; when it swings to the left, it rotates to a position above the hydraulic clamp 200; when the telescopic mechanism 40 drives the slide plate 30 to descend, it lowers the lifting position of the workpiece 300; when the telescopic mechanism 40 drives the slide plate 30 to rise, it raises the workpiece 300 above the hydraulic clamp 200. With this structure, the workpiece 300 can be placed on the unloading seat 50 at a low position outside the gear shaper. Then, by the rising and rotating of the unloading seat 50, the workpiece 300 is moved to a position above the hydraulic clamp 200. Afterward, the unloading seat 50 descends, loading the workpiece 300 into the hydraulic clamp 200. This avoids the safety hazards associated with hoisting the workpiece to a high position using lifting equipment and then manually pulling and pushing it into the hydraulic clamp.

[0039] In this embodiment, the feeding seat 50 is directly hinged to the slide plate 30.

[0040] It should be noted that a rotary table 100 is mounted on the base of the gear shaping machine, and a hydraulic clamp 200 is installed at the center of the rotary table 100. During machining, the workpiece 300 rotates with the rotary table 100. The workpiece 300 is a shaft-type workpiece with different diameters at both ends, thus forming a step in the middle. During machining, the tooth groove is machined at the top of the workpiece 300.

[0041] See Figure 3 , 4 An annular flange 511 is provided inside the limiting hole 51, and a limiting platform 512 is formed on the upper side of the limiting hole 511. In use, the lower end of the workpiece 300 is inserted into the limiting hole 51 on the feeding seat 50, and the step of the workpiece 300 abuts against the limiting platform 512.

[0042] Furthermore, the top of the limiting hole 51 is provided with a flared opening 513, which serves as a guide to facilitate the insertion of the lower end of the workpiece 300.

[0043] Furthermore, see Figure 3 The feeding seat 50 is provided with a notch 52, which communicates with the limiting hole 51. By providing the notch 52, the workpiece 300 can be moved laterally into the limiting hole 51 through the notch 52, further reducing the lifting height of the workpiece 300 during loading. During processing, the width of the notch 52 can be adapted to the diameter of the lower end of the workpiece 300.

[0044] In this embodiment, see Figure 1 , 2 The base 10 includes a side plate 11 and a support 12. The support 12 is welded and fixed to the side plate 11. The sliding mechanism 20 is located on the side of the side plate 11 away from the support 12. The support 12 has a longitudinal cavity 13. The telescopic mechanism 40 is fixedly installed in the cavity 13.

[0045] The telescopic end 41 of the telescopic mechanism 40 extends upward, and the upper end of the slide plate 30 is fixedly connected to one end of the connecting plate 31. The other end of the connecting plate 31 extends above the cavity 13 and is fixedly connected to the telescopic end 41 of the telescopic mechanism 40. The slide plate 30 is driven to move up and down by the extension and retraction of the telescopic mechanism 40.

[0046] Specifically, the telescopic mechanism 40 can be one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0047] In this embodiment, the telescopic mechanism 40 is a hydraulic cylinder, see [link to documentation]. Figure 1 , 2 The telescopic end 41 of the hydraulic cylinder is the piston rod end, which has a screw. After the screw passes through the connecting plate 31, a nut is installed to fix the connecting plate 31. The cylinder body is mounted on the side plate 11 via its own lug 14.

[0048] In this embodiment, see Figure 1 , 2 The sliding mechanism 20 includes linear guide rails 21 and sliders 22. Two linear guide rails 21 are longitudinally spaced and parallel to each other on the base 10. Two sliders 22 are respectively installed on the slide plate 30 at the positions corresponding to the linear guide rails 21. The sliders 22 are slidably connected to the linear guide rails 21.

[0049] Example 2:

[0050] The difference in Embodiment 1 is that, in this embodiment, the feeding seat 50 is mounted on the slide plate 30 via a hinge mechanism 60.

[0051] For details, see Figure 1 , 2 A hinge mechanism 60 is mounted on the slide plate 30, and the feeding seat 50 is mounted on the hinge mechanism 60. (See also...) Figure 5 , 6 The hinge mechanism 60 includes a first hinge plate 61, a second hinge plate 62, and a pivot 63. One end of the first hinge plate 61 is provided with a slot 611, and one side of the second hinge plate 62 is provided with a protrusion 621. The protrusion 621 is inserted into the slot 611. The first hinge plate 61 and the second hinge plate 62 are provided with through hinge holes at the positions corresponding to the slot 611 and the protrusion 621. The pivot 63 is inserted into the hinge hole. The first hinge plate 61 is mounted on the slide plate 30. The feeding seat 50 is connected to the second hinge plate 62. The second hinge plate 62 rotates around the pivot 63.

[0052] In addition, to facilitate installation and height adjustment, the first hinge plate 61 is provided with at least two countersunk holes 612, and the slide plate 30 is provided with a pair of threaded holes longitudinally. The threaded end of the bolt passes through the countersunk hole 612 and is then screwed into the threaded hole on the slide plate 30 for fixation. By connecting with the threaded holes at different heights on the slide plate 30, the installation height of the hinge mechanism 60 can be adjusted.

[0053] It should be noted that in Embodiment 1, the feeding seat 50 is directly pivotally mounted to the slide plate 30, and is also mounted using a structure similar to the hinge mechanism 60.

[0054] Example 3:

[0055] Based on Example 2, see Figure 1 , 2 A transition piece 70 is installed on the second hinge plate 62, and the feeding seat 50 is installed on the transition piece 70. By setting the transition piece 70, it is easy to reduce the lifting height of the workpiece and to easily replace the feeding seat 50 as needed.

[0056] In this embodiment, see Figure 7 ,8 The transition piece 70 includes a longitudinal block 71 and a transverse block 72. The transverse block 72 is fixed to the lower end of the longitudinal block 71. The upper end of the longitudinal block 71 is installed and fixed to the second hinge plate 62. The transverse block 72 is provided with a clearance opening 73. The material feeding seat 50 is detachably installed on the transverse block 72 by bolts, and the clearance opening 73 corresponds to the position of the limiting hole 51.

[0057] Specifically, see Figure 3 The feeding seat 50 has two first mounting holes 53, and the transverse block 72 has two second threaded holes 721. The feeding seat 50 is mounted on the transverse block 72. The threaded end of the bolt passes through the first mounting hole 53 and is then screwed into the second threaded hole 721 for fixation. The longitudinal block 71 has a boss 712, and the second hinge plate 62 has a groove 621. The boss 712 is installed into the groove 621. The longitudinal block 71 has a second mounting hole 711, and the second hinge plate 62 has a first threaded hole 622. The threaded end of the bolt passes through the second mounting hole 711 and is then screwed into the first threaded hole 622 for fixation.

[0058] Example 4:

[0059] Based on Embodiment 1, Embodiment 2, or Embodiment 3, this utility model also discloses a gear hobbing machine, which is equipped with the aforementioned auxiliary feeding mechanism.

[0060] Specifically, the base 10 of the auxiliary feeding mechanism is mounted on the base of the gear hobbing machine.

[0061] The method of use or principle of this utility model:

[0062] See Figure 2 When the feeding seat 50 swings to the right, the feeding seat 50 moves away from the rotary table 100 of the gear hoist. Then the telescopic mechanism 40 drives the slide plate 30 to descend, lowering the position of the feeding seat 50. The workpiece 300 is then hoisted and placed into the feeding seat 50 by the lifting equipment, and the lower end of the workpiece 300 passes through the limiting hole 51 on the feeding seat 50.

[0063] Then, the slide plate 30 is driven to rise by the telescopic mechanism 40, and the step on the workpiece 300 abuts against the unloading seat 50, raising the workpiece 300 above the hydraulic clamp 200.

[0064] Then push the feeding seat 50 again, see Figure 2 The unloading seat 50 is rotated to the left, causing the workpiece 300 to rotate to a position directly above the hydraulic clamp 200. Then, the sliding plate 30 is driven to descend via the telescopic mechanism 40, allowing the workpiece 300 to enter the hydraulic clamp 200.

[0065] When the workpiece is being processed, the material feeding seat 50 is placed outside the workpiece 300, but does not abut against the step on the workpiece 300.

[0066] After the workpiece 300 is processed, the sliding plate 30 is driven to rise by the telescopic mechanism 40, raising the workpiece 300 above the hydraulic clamp 200. Then, the unloading seat 50 is pushed to the right, moving it away from the rotary table 100 of the gear shaper. After that, the telescopic mechanism 40 drives the sliding plate 30 to descend, lowering the position of the unloading seat 50. The workpiece 300 is then lifted out of the unloading seat 50 by a lifting device.
