Description

Technical Field

[0001] The utility model belongs to the technical field of tooling fixtures, and in particular relates to a tooling for milling the joint surface of a worm reducer case. Background Art

[0002] A worm gear reducer is a power transmission mechanism that reduces speed while increasing output torque. It can be self-locking, and with the output and input shafts arranged at 90°, it can achieve a high speed ratio with very low noise. Therefore, it is widely used in current engineering applications for transmitting power and motion.

[0003] The processing of the housing of this type of reducer is complicated due to its complex shape and difficult positioning. The milling of the mating surface of the housing requires clamping. In order to achieve rapid installation, the prior art provides a reference. Application No. 2016210533492 discloses a milling clamping device for the mating surface of a worm reducer housing. The inventor believes that: in combination with its accompanying drawings, it can be seen that when clamping, multiple screws need to be screwed, and the clamping efficiency is low. The inventor provides a milling tool. Utility Model Content

[0005] The technical solution adopted by the utility model is: a milling tool for the joint surface of a worm reducer housing, comprising a base plate;

[0006] A side support plate is provided on the left side of the top of the base plate, and the side support plate is fixed to the top of the base plate by connecting screws;

[0007] A support plate is provided on the right side of the top of the base plate, a screw is arranged horizontally and is spirally connected to the support plate, a side pressure plate is provided at one end of the screw close to the center of the base plate, and a hand wheel is provided at the other end;

[0008] A pressing plate is provided on the front side of the top of the base plate, and the pressing plate is connected to the top of the base plate via locking screws.

[0009] Furthermore, the surface of the side pressure plate in contact with the worm reducer housing workpiece to be processed is provided with anti-slip grooves.

[0010] Optionally, the side support plate is formed in an "L" shape.

[0011] Beneficial effects:

[0012] The tooling has the advantages of simple structure, convenient clamping, reliable positioning and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0025] See also Figures 1 to 2 , a worm reducer housing joint surface milling tool, including a base plate 1;

[0026] A side support plate 4 is provided on the left side of the top of the base plate 1, and the side support plate 4 is fixed to the top of the base plate 1 by connecting screws 5;

[0027] The side support plate 4 is formed into an "L" shape (i.e., it includes a horizontal part and a vertical part). The worm reducer housing workpiece to be processed is attached to the vertical part of the side support plate 4. The connecting screws 5 are set at the position of the horizontal part. The horizontal part has a larger contact surface with the base plate 1 and has higher strength.

[0028] A support plate 6 is provided on the right side of the top of the base plate 1, and a screw rod 8 is arranged horizontally and spirally connected to the support plate 6. A side pressure plate 9 is provided at one end of the screw rod 8 close to the center of the base plate 1, and a hand wheel 7 is provided at the other end;

[0029] By rotating the hand wheel 7, the side pressure plate 9 can be quickly driven to squeeze the side of the worm reducer housing workpiece to be processed;

[0030] A pressure plate 3 is provided on the front side of the top of the base plate 1, and the pressure plate 3 is connected to the top of the base plate 1 by a locking screw 2;

[0031] Through the fixation on both sides and the pressure plate 3 in the front, the positioning is reliable and efficient.

[0032] In order to improve the anti-slip effect, the surface of the side pressure plate 9 that contacts the worm reducer housing workpiece to be processed is provided with anti-slip grooves.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
