Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a gear processing seat. Background Art

[0002] Gears are mechanical components with teeth on the rim that can continuously mesh to transmit motion and power. During the gear processing process, the gears need to be stably clamped on the processing seat. Although the existing processing seat can stably clamp the gears, the clamping position often needs to be adjusted during the processing. The existing processing seat needs to remove the gear when adjusting the angle, and then clamp it again after adjusting to the appropriate angle and size, which is inefficient. Utility Model Content

[0009] Furthermore, an anti-slip support block is provided at the lower end of the fixing seat.

[0010] The utility model has the following advantages: when the angle needs to be adjusted, it is only necessary to operate the wheel hub pressing mechanism to disengage from the gear, and then toggle the extension plate to rotate the sliding seat relative to the fixed seat. After it reaches a suitable position, the gear angle can be adjusted. The wheel hub pressing mechanism can be operated again to press downward to tighten it.

[0022] refer to Figure 1-4 As shown, one embodiment of the utility model is:

[0023] A gear processing seat comprises a fixed seat 1, on which a sliding seat 2 is rotatably mounted, on which a first axial hole positioning protrusion 3 is provided, an extension plate 4 is provided on the outer side of the sliding seat 2, and the extension plate 4 is provided with a gear fixing mechanism, and an outer side wall of the fixed seat 1 is provided with a mounting frame 5, an upper cantilever 51 of the mounting frame 5 is located above the sliding seat 2, and a hub pressing mechanism is provided on the upper cantilever 51.

[0024] Specifically, the wheel hub pressing mechanism includes a first screw rod 6 passed through the upper cantilever 51, a wheel hub pressing plate 7 is rotatably mounted on the lower end of the first screw rod 6, a second axial hole positioning protrusion 8 is provided at the lower end of the wheel hub pressing plate 7, and a first driving handle 9 is provided at the upper end of the first screw rod 6.

[0025] The gear fixing mechanism includes a mounting block 10, on which a second screw 11 is passed, and a connecting plate 12 is rotatably mounted at one end of the second screw 11 close to the first axial hole positioning protrusion 3, on which a gear plug block 13 is provided, and a second driving handle 14 is provided at the other end of the second screw 11.

[0026] The gear is pre-clamped on the sliding seat 2, and then the first driving handle is used to make the hub pressure plate 7 press the hub of the gear downward, so that the gear is tightly attached to the sliding seat 2, and the friction between the sliding seat 2 and the fixed seat 1 is increased to avoid relative rotation. Then the second driving handle 14 is used to make the gear tooth block 13 cooperate with the gear teeth to achieve the fastening and clamping of the gear. When the angle needs to be adjusted, it is only necessary to operate the first driving handle 9 to disengage the hub pressure plate 7 from the gear, and then the extension plate 4 is moved to make the sliding seat 2 rotate relative to the fixed seat 1. After reaching the appropriate position, the gear angle can be adjusted. The first driving handle is operated again to press the hub pressure plate 7 downward to tighten it. The operation is simple and convenient, and there is no need to disassemble the gear, which is more efficient.

[0027] In this embodiment, a circular positioning block 15 is provided at the center of the upper end surface of the fixed seat 1 , and a groove adapted to the circular positioning block 15 is provided at the lower end of the sliding seat 2 , and the depth of the groove is greater than the height of the circular positioning block 15 .

[0028] The depth of the groove is greater than the height of the circular positioning block 15, so that the hub pressure plate can increase the friction between the sliding seat 2 and the fixed seat 1 when pressing downward, thereby achieving the fixation of the sliding seat 2 and the fixed seat 1 and ensuring smooth gear processing operations.

[0029] The lower end of the fixing seat 1 is provided with an anti-slip support block 16

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
