Description

Technical Field

[0001] This utility model relates to the field of gear processing, specifically to a gear processing vacuum milling device. Background Technology

[0002] Gear milling is a process in which a milling cutter cuts into a gear blank. External gear milling involves using a gear milling cutter to cut the surface of the workpiece, gradually forming the tooth profile of the external gear. This process is typically suitable for small-batch production and machining complex gears, offering high flexibility. During machining, the relative movement between the gear milling cutter and the workpiece gradually shapes the desired tooth profile.

[0003] Traditional mechanical clamps often require clamping components for clamping. During the clamping process, the mechanical clamp is prone to contact with the gear surface or uneven force, which may cause scratches, dents or other deformations on the gear surface. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] First embodiment:

[0026] See Figures 1-4 As shown, this utility model provides a gear processing vacuum milling device, including a base plate 1, which is fixedly installed inside the processing equipment by bolts. A negative pressure box 2 is installed on the surface of the base plate 1. The negative pressure box 2 is cylindrical and vertically arranged. A vacuum machine 3 is provided on the outside of the negative pressure box 2 to create a negative pressure inside the negative pressure box 2. The vacuum machine 3 can exhaust the gas inside the negative pressure box 2 and help to create a negative pressure inside the negative pressure box 2.

[0027] Three sliding frames 4 are evenly connected to the outside of the negative pressure box 2. The sliding frames 4 are circumferentially distributed with the axis of the negative pressure box 2 as the reference. An adsorption frame 5 is slidably connected to the outer end of the sliding frame 4. The upper surface of the adsorption frame 5 is provided with a top hole 501 that communicates with the inside of the adsorption frame 5. The adsorption frame 5 is connected to the negative pressure box 2 through a pipe with a solenoid valve.

[0028] When the device is in use, it is fixed by fixing the base plate 1 to the milling equipment. Depending on the size of the gear, the adsorption frame 5 slides on the sliding frame 4, which can be adapted to the auxiliary fixation of gears of different sizes. When the gear is set on the adsorption frame 5, the adsorption frame 5 connected to the negative pressure box 2 forms a negative pressure structure after the solenoid valve is opened. The top hole 501 is used to achieve vacuum adsorption fixation of the bottom of the gear, thereby assisting the gear to perform tooth surface milling on the outer circle surface.

[0029] The top hole 501 is tapered, with its large end extending to the upper surface of the adsorption frame 5. When the bottom surface of the gear contacts the top hole 501, the top hole 501 is used to fix the bottom surface of the gear, so as to facilitate milling of the outer tooth surface of the gear.

[0030] The second embodiment differs from the first embodiment in that:

[0031] The sliding frame 4 is right-angled. The vertical end of the sliding frame 4 is connected to the base plate 1, and the horizontal end of the sliding frame 4 is connected to the negative pressure box 2. The bottom of the adsorption frame 5 is provided with a sliding sleeve 503, which slides in cooperation with the horizontal end of the sliding frame 4. By utilizing the sliding cooperation between the sliding sleeve 503 and the horizontal end of the sliding frame 4, the sliding sleeve 503 is guided, which assists in the position adjustment of the adsorption frame 5, so that the adsorption frame 5 can adapt to the machining of gear tooth surfaces of various diameters.

[0032] The horizontal end of the sliding frame 4 is provided with scale markings corresponding to the adsorption frame 5, so that the position of the adsorption frame 5 can be observed through the scale markings. In addition, the adsorption frame 5 is threadedly connected to the locking bolt 502 corresponding to the sliding frame 4. After the adsorption frame 5 is adjusted to a suitable position, tightening the locking bolt 502 will make the bottom end of the locking bolt 502 in close contact with the sliding frame 4, thereby locking the adsorption frame 5. After loosening the locking bolt 502, the position of the adsorption frame 5 can be adjusted by sliding the sliding sleeve 503 and the sliding frame 4.

[0033] The third embodiment differs from the first embodiment in that:

[0034] The negative pressure box 2 is provided with a rotating groove 201 at the top, and a rotating block 6 is rotatably connected in the rotating groove 201. A sliding sleeve 503 is rotatably connected between the rotating block 6 and the adsorption rack 5. The outer wall of the negative pressure box 2 is provided with a fixing bolt 601 for locking the rotating block 6. When adjusting the position of the adsorption rack 5, the fixing bolt 601 is loosened, and the rotating block 6 can be rotated. The fixing bolt 601 can be used to pull the adsorption rack 5 to slide on the sliding rack 4 to realize the position adjustment of the adsorption rack 5. After the adjustment is completed, the fixing bolt 601 is tightened to fix the rotating block 6. All adsorption racks 5 can be fixed in one adjustment process, and the fixing effect is good.

[0035] Furthermore, the negative pressure box 2 or the rotating block 6 is provided with an insertion hole 8 at its high end, and also includes an inner hole frame 7. The bottom end of the inner hole frame 7 is inserted into the insertion hole 8 with a corresponding insertion block 701. By using the insertion hole 8 and the insertion block 701, the inner hole frame 7 can be auxiliaryly fixed. By using the cooperation between the inner hole frame 7 and the inner ring of the gear, the gear can be positioned. When the bottom surface of the gear contacts the adsorption frame 5, the negative pressure formed by the top hole 501 on the adsorption frame 5 can be used to fix the gear. Furthermore, the insertion hole 8 is a regular polygonal groove.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
