Description

Technical Field

[0001] The utility model belongs to the technical field of clamps, and in particular relates to a spiral bevel gear clamp. Background Art

[0002] Spiral bevel gears are spiral bevel gears, which are commonly used for motion and power transmission between two intersecting axes. The teeth of bevel gears are distributed on the surface of a cone, and their tooth shape gradually decreases from the large end to the small end. Spiral bevel gears have high transmission efficiency, stable transmission ratio, large arc overlap coefficient, high load capacity, smooth transmission, reliable operation, compact structure, energy saving, material saving, space saving, wear resistance, long life and low noise.

[0003] The processing of spiral bevel gears requires multiple steps to complete, such as Figure 5 The active spiral bevel gear shown in the figure has a mounting handle with dimensions of D1 and D2 in addition to the bevel gear part. The grinding of the gear mounting handle is essential in the gear processing process, but due to the particularity of the bevel gear structure, the grinding of the mounting handle has no clamping and fixing point, so the processing of this part cannot be carried out continuously.

[0004] The patent document with the publication number CN209716668U discloses a workpiece fixture for a forced motion chain bevel gear rolling mill, which is used to install and position the processed spiral bevel. The workpiece fixture for the forced motion chain bevel gear rolling mill includes a main shaft with a hollow arrangement, a fixture base fixed on the main shaft for coaxially positioning the processed spiral bevel, and a spiral bevel locking mechanism coaxially arranged with the main shaft for passing through the main shaft to coaxially position the fixture base to lock the processed spiral bevel on the main shaft. However, the fixture clamps the mounting handle together, and the mounting handle cannot be subsequently processed. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a spiral bevel gear clamp.

[0006] The utility model is realized through the following technical solutions.

[0007] The utility model provides a spiral bevel gear clamp, comprising a chuck disc and a fixing piece, wherein the chuck disc and the fixing piece are connected, a port A is arranged at one end of the chuck disc, a port B is arranged at the other end of the chuck disc, and a groove A is arranged in the chuck disc.

[0008] Preferably, the chuck disk is annular, a screw hole is arranged on the chuck disk, and the chuck disk is threadedly connected to the fixing member through the screw hole.

[0009] Preferably, an arc-shaped portion A is provided on one side of the port A, and an arc-shaped portion B is provided on the other side of the port A.

[0010] Preferably, the diameter of port A is greater than the diameter of port B.

[0011] Preferably, a groove B is arranged inside the groove A.

[0012] Preferably, the groove A is arranged in a V shape.

[0013] Preferably, the groove B has a rectangular cross section.

[0014] The beneficial effects of the utility model are:

[0015] The utility model provides two balanced fixing points for the chuck plate to the spiral bevel gear through the setting of the fixing piece and the groove B, and common screws can be used as fixing pieces, which effectively reduces the production cost of the fixture. The utility model has a simple structure and is easy to use. It can clamp the bevel gear part without contacting the mounting handle part, provides the clamping position required for subsequent processing, and solves the problem of no clamping position in the subsequent processing process.

[0022] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0023] Example:

[0024] like Figures 1 to 4 As shown, a spiral bevel gear fixture includes a chuck plate 1 and a fixing member 2, wherein the chuck plate 1 and the fixing member 2 are connected, a port A3 is arranged at one end of the chuck plate 1, a port B4 is arranged at the other end of the chuck plate 1, and a groove A5 is arranged inside the chuck plate 1. The chuck plate 1 is made of 45 steel. The fixing member 2 can be a screw.

[0025] The chuck plate 1 is annular, and a screw hole 6 is provided on the chuck plate 1. The chuck plate 1 is threadedly connected to the fixing member 2 through the screw hole 6. The fixing member 2 penetrates one side of the chuck plate 1 and is connected. After the spiral bevel gear is installed in the chuck plate 1, the fixing member 2 is arranged between the spiral bevel gear and the port A3 to secure the spiral bevel gear in the chuck plate 1. The distance that the fixing member 2 extends into the chuck plate 1 can be adjusted by rotation, thereby adjusting the clamping tightness and adapting to spiral bevel gears of different specifications.

[0026] The arc portion A7 is disposed on one side of the port A3, and the arc portion B8 is disposed on the other side of the port A3. The arc portion B8 has a smaller diameter on one side, and is used to provide a space for arranging the groove B9.

[0027] The diameter of the port A3 is greater than the diameter of the port B4, so as to prevent the spiral bevel gear from coming out from the side of the port B4.

[0028] A groove B9 is arranged in the groove A5, and the groove B9 is arranged on the side close to the arc-shaped portion B8. The screw hole 6 is arranged on the opposite side of the groove B9.

[0029] The groove A5 is arranged in a V shape, that is, the inner wall of the groove A5 is an inclined surface, and the inclined surface can be arranged according to the spiral bevel gear to be clamped, so that the groove A5 can fit the spiral bevel gear.

[0030] The groove B9 has a rectangular cross section and is used to clamp the outer diameter of the bevel gear part.

[0031] When in use, first insert the side of the spiral bevel gear into the groove B9, then place the other side of the spiral bevel gear into the groove A5 and fit it, screw the fixing part 2 into the screw hole 6, and complete the clamping operation until the fixing part 2 contacts the spiral bevel gear and is clamped.
