Description

Technical Field

[0001] This utility model relates to the field of water distributor technology, and in particular to a deburring fixture for the main body of a plastic water distributor. Background Technology

[0002] The molding of plastic manifolds mainly relies on injection molding machines. The plastic material is melted under high temperature and pressure, and then injected into the mold cavity through an injection cylinder. After molding, the plastic manifold requires further processing, such as deburring.

[0003] The structure of the plastic manifold is shown in the attached instruction manual. Figure 1 As shown in the figure, there are burrs at the circular opening at position A. The common method of deburring is to use sandpaper. However, since the pipes of the water distributor are small and the space for manual operation is limited, the method of deburring with sandpaper has the problems of low work efficiency and poor sanding quality. Therefore, a deburring fixture for the main body of a plastic water distributor is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a deburring fixture for the main body of a plastic water distributor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A deburring fixture for a plastic water separator body includes a mounting base. The mounting base contains a double-layered worm gear. A worm is positioned on one side of each worm gear to mesh with it. A first drive shaft is located at the center of rotation of the upper worm gear, and a second drive shaft is located at the center of rotation of the lower worm gear. The second drive shaft extends downwards from the bottom of the mounting base. The lower end of the second drive shaft is rotatably connected to a mounting bracket via a slewing bearing. A bevel gear assembly is located inside the mounting bracket. The second drive shaft is hollow and allows the first drive shaft to pass through. The lower end of the first drive shaft extends into the mounting bracket and is connected to the bevel gear assembly. The output shaft of the bevel gear assembly is designed as a fixed shaft. A coaxially rotating tool holder is fitted onto the fixed shaft. A tool spindle is mounted on the tool holder, and a milling cutter is mounted at the output end of the tool spindle.

[0007] In a preferred embodiment, the mounting bracket is U-shaped, and the bevel gear assembly includes two meshing bevel gears, one of which is mounted on the cross arm of the mounting bracket, and the other is mounted on the side arm of the mounting bracket.

[0008] In a preferred embodiment, the lower end of the first drive shaft is rotatably connected to a bevel gear located on the cross arm of the mounting bracket.

[0009] In a preferred embodiment, the mounting base is further equipped with servo motors that control the rotation of the worm gears of the upper and lower layers.

[0010] In a preferred embodiment, the fixed shaft is rotatably connected to a bevel gear on the side arm of the mounting bracket, and the distal end of the fixed shaft is rotatably fixed on the other side arm of the mounting bracket.

[0011] The beneficial effects of this utility model are:

[0012] The deburring fixture proposed in this solution solves the problems of low efficiency and poor grinding quality when using sandpaper to polish plastic manifolds. It replaces sandpaper polishing with milling with a milling cutter. The milling angle of the milling cutter can be adjusted according to the actual situation, which greatly improves the efficiency of deburring. Moreover, the internal space of the manifold has little impact on the polishing, effectively ensuring the polishing quality of the manifold. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In this embodiment, refer to Figure 1-3 The deburring fixture for the main body of the plastic water distributor includes a mounting base 1. The mounting base 1 has a double-layered worm gear 2 inside, with a worm 3 meshing with each worm gear 2 on one side. The mounting base 1 also contains servo motors for controlling the rotation of the upper and lower worm gears 3. The transmission processes of the upper and lower worm gears 2 and worm gears 3 are relatively independent and do not affect each other.

[0019] The upper worm gear 2 has a first drive shaft 4 at its center of rotation, and the lower worm gear 2 has a second drive shaft 5 at its center of rotation. The second drive shaft 5 extends downward from the bottom of the mounting base 1. The lower end of the second drive shaft 5 is rotatably connected to the mounting bracket 6 through the slewing bearing 12. The mounting bracket 6 has a bevel gear assembly 7 inside.

[0020] The mounting bracket 6 has a U-shaped design, and the bevel gear assembly 7 includes two meshing bevel gears, one of which is located on the cross arm of the mounting bracket 6, and the other is located on the side arm of the mounting bracket 6.

[0021] The second drive shaft 5 is hollow inside and allows the first drive shaft 4 to pass through. The lower end of the first drive shaft 4 extends into the mounting bracket 6 and is rotatably connected to the bevel gear on the cross arm of the mounting bracket 6.

[0022] The output shaft of the bevel gear assembly 7 is designed as a fixed shaft 8, which is rotatably connected to the bevel gear on the side arm of the mounting bracket 6, and the far end of the fixed shaft 8 is rotatably fixed on the other side arm of the mounting bracket 6.

[0023] A tool holder 9, which rotates coaxially, is sleeved on a fixed shaft 8. A tool spindle 10 is mounted on the tool holder 9, and a milling cutter 11 is mounted on the output end of the tool spindle 10.

[0024] Combined with appendix Figure 2 It can be seen that the rotation of the lower worm gear 2 drives the mounting bracket 6 to rotate around the second drive shaft 5 via the second drive shaft 5; while the rotation of the upper worm gear 2 drives the bevel gear assembly 7 to rotate via the first drive shaft 4, and ultimately drives the tool holder 9 to rotate around the fixed shaft 8. Under the control of the first drive shaft 4 and the second drive shaft 5, the milling cutter 11 can freely adjust its position within the space, thus adapting to the deburring of different local areas at the circular opening of the distributor. This greatly improves the deburring efficiency, and the internal space of the distributor has little impact on the grinding, effectively ensuring the grinding quality of the distributor.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
