Description

Technical Field

[0001] This utility model relates to the field of gear shaping machine equipment, and in particular to a gear shaping angle adjustment device for a reverse bevel gear shaping machine. Background Technology

[0002] Gear shapers use gear shapers as cutting tools to machine the tooth profiles of gears, racks, etc. During the machining process, the gear shaper makes a reciprocating cutting motion while simultaneously rolling relative to the workpiece. When machining inverted bevel gears, the machine tool and the workpiece need to be at a certain angle, that is, the spindle of the gear shaper's worktable and the cutter spindle need to be tilted at an appropriate angle. Ordinary gear shapers, because their worktables do not have a tilting mechanism, cannot adjust the tilt angle, which limits the machining of inverted bevel gears due to their structure.

[0003] CN201862866U discloses a table flipping mechanism for a gear shaping machine, which adjusts the relative angle between the workpiece and the cutting tool by flipping the table. The structure is relatively complex. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a gear shaping angle adjustment device for a reverse bevel gear shaping machine. By adjusting the angle of the column of the gear shaping machine, the relative angle between the tool and the workpiece can be adjusted, which is beneficial for processing reverse bevel gears with different angles.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a gear shaping angle adjustment device for a bevel gear shaping machine, including a flipping support mechanism, the flipping support mechanism including a flipping base, the flipping base being set on the machine tool base of the gear shaping machine, a rotating shaft support seat being provided at one end of the flipping base near the machine tool spindle, a flipping mechanism being provided at the lower end of the column of the gear shaping machine, the flipping mechanism including a flipping pad, the flipping pad being rotatably mounted on the rotating shaft support seat via a rotating shaft, a first hydraulic cylinder support seat being provided at one end of the column of the gear shaping machine away from the machine tool spindle, a second hydraulic cylinder support seat being provided on one side of the flipping base, the tail of the flipping hydraulic cylinder being hinged to the first hydraulic cylinder support seat, and the telescopic end of the flipping hydraulic cylinder being hinged to the second hydraulic cylinder support seat.

[0006] In a preferred embodiment, a support base is provided on the lower side of the end of the flipping pad away from the rotation axis, and an angle pad is provided between the support base and the flipping base.

[0007] In a preferred embodiment, the angle pads are provided in multiple specifications, and the column of the gear hobbing machine is rotated to different angles to correspond to angle pads of different thicknesses.

[0008] In a preferred embodiment, the lower end of the support base has a spherical structure.

[0009] In a preferred embodiment, clamping mechanisms are provided on both sides of the flip base. The clamping mechanisms include support side plates installed on the flip base, and clamping cylinders are provided on the support side plates. The clamping cylinders clamp the flip pad to restrict its rotation.

[0010] The present invention provides a tooth-shaping angle adjustment device for a reverse bevel gear shaping machine, which has the following beneficial effects:

[0011] 1. By rotating the hydraulic cylinder, the column rotates along the axis of rotation, so that the machine tool spindle and the center line of the worktable are at a certain angle, namely the angle of the inverted bevel gear. This facilitates the gear shaping of inverted bevel gears with different tapers. It is easy to adjust, has a simple structure, and is beneficial to production and manufacturing.

[0012] 2. During the flipping process of the flipping pad, the angle is flipped with the rotation axis as the reference to ensure the relative accuracy of the machine tool.

[0013] 3. After the flipping adjustment is in place, the clamping cylinder extends to lock the flipping pad, limiting the flipping pad to rotate 300 degrees and ensuring stable operation of the machine tool. Attached Figure Description

[0017] In the diagram: gear hobbing machine 100, machine tool base 110, machine tool spindle 120, column 130, worktable 140; tilting support mechanism 200, tilting base 210, rotating shaft support seat 220, second cylinder support seat 230; tilting mechanism 300, tilting pad 310, rotating shaft 320, support seat 330; first cylinder support seat 400; tilting cylinder 500; angle pad 600; clamping mechanism 700, support side plate 710, clamping cylinder 720. Detailed Implementation

[0018] Example 1:

[0019] like Figures 1-2 As shown, a gear shaping angle adjustment device for a bevel gear shaping machine includes a flip support mechanism 200, which is mounted on the machine tool base 110 of the gear shaping machine 100. The flip support mechanism 200 includes a flip base 210, which is fixed on the machine tool base 110. A rotating shaft support seat 220 is provided at one end of the flip base 210 near the machine tool spindle 120.

[0020] The lower end of the column 130 of the gear hobbing machine 100 is provided with a flipping mechanism 300 for mounting the column 130. The flipping mechanism 300 includes a flipping pad 310, which is rotatably mounted on the rotating shaft support 220 via a rotating shaft 320, so that the column 130 can be flipped along the rotating shaft 320.

[0021] The gear shaper 100 has a first hydraulic cylinder support 400 at one end of the column 130 away from the machine tool spindle 120, and a second hydraulic cylinder support 230 on one side of the tilting base 210. The tail of the tilting cylinder 500 is hinged to the first hydraulic cylinder support 400, and the telescopic end of the tilting cylinder 500 is hinged to the second hydraulic cylinder support 230. By extending and retracting the tilting cylinder 500, the column 130 of the gear shaper 100 is driven to rotate along the rotating shaft 320.

[0022] In practical use, the workpiece is fixed on the worktable 140, and the gear shaping tool is mounted on the machine tool spindle 120. By extending and retracting the tilting cylinder 500, the column 130 rotates along the rotating shaft 320, so that the machine tool spindle 120 and the center line of the worktable 140 generate a certain angle (reverse bevel angle), thereby adjusting the relative angle between the tool and the spindle of the worktable 140, which facilitates the gear shaping of reverse bevel teeth with different tapers.

[0023] During the flipping process of the flipping pad 310, the angle is flipped with the rotating axis 320 as the reference to ensure the relative accuracy of the machine tool.

[0024] Example 2:

[0025] Unlike Embodiment 1, the flipping pad 310 has a support base 330 on the lower side of the end away from the rotation axis 320, and an angle pad 600 is provided between the support base 330 and the flipping base 210.

[0026] Because the column 130 of the gear hobbing machine 100 rotates at different angles, the height between the support base 330 and the rotating base 210 is different. Therefore, the angle pad 600 is set with multiple specifications. When the column 130 of the gear hobbing machine 100 rotates to different angles, the angle pad 600 with different thicknesses corresponds to the angle pad 600.

[0027] Once the rotation adjustment is in place, the column 130 is supported by the angle pad 600 to improve the operational stability of the equipment.

[0028] Preferably, the lower end of the support base 330 is a spherical structure. By setting the support base 330 to a spherical structure, reliable contact between the support base 330 and the angle pad 600 is ensured.

[0029] Example 3:

[0030] Preferably, unlike Embodiment 1, the flip base 210 is provided with clamping mechanisms 700 on both sides. The clamping mechanism 700 includes a support side plate 710 mounted on the flip base 210, and a clamping cylinder 720 is provided on the support side plate 710. The extension and retraction direction of the clamping cylinder 720 is consistent with the length direction of the rotation shaft 320.

[0031] Once the flipping adjustment is in place, the clamping cylinder 720 extends to lock the flipping pad 310, restricting the rotation of the flipping pad 300 and ensuring stable machine operation.

[0032] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The embodiments and features described in this application can be arbitrarily combined without conflict. The protection scope of this utility model should be defined as the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
