Before describing the present invention with reference to the accompanying drawings, it should be particularly noted that the technical solutions and features provided in the various parts of the present invention, including the following description, can be combined with each other without conflict.

[0022] Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the protection scope of the present invention.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The specific implementation process is as follows:

[0024] like Figures 1-3 As shown, this utility model provides an automatic grinding machine, including: a tooling table 1, a positioning tooling and a grinding tooling;

[0025] Tooling table 1, which is a frame structure;

[0026] The positioning fixture includes a clamping mechanism and a rotating support mechanism. The rotating support mechanism includes a bottom motor 3, a support plate 4, and a rotating seat 5. The support plate 4 is mounted on the top of the fixture table 1, and the rotating seat 5 is mounted on the support plate 4 via bearings. The rotating seat 5 is driven to rotate by the bottom motor 3. A fixture is provided on the top of the rotating seat 5 for mounting the product 2 to be polished. The bottom motor 3 is mounted on the bottom of the support plate 4 via a motor base. The clamping mechanism includes a clamping cylinder 6 and a positioning arm 7. The clamping cylinder 6 is used to drive the positioning arm 7 to move up and down. The positioning arm 7 is horizontally positioned and extends toward the center of the rotating seat 5. A positioning block 8 is mounted on the positioning arm 7 to limit the position of the product 2.

[0027] The polishing fixture includes a polishing wheel 9 and a polishing drive motor 10. The polishing drive motor 10 is used to drive the polishing wheel 9 to rotate, thereby polishing the product 2. The polishing wheel 9 is configured such that its axis is perpendicular to the axis of the rotating seat 5.

[0028] The working process of the automatic polishing machine is as follows: Product 2 is placed on the rotating support mechanism - the clamping mechanism fixes Product 2 - the motor at the bottom drives Product 2 and the tooling to rotate - the polishing drive motor 10 drives the polishing wheel 9 to rotate, and at the same time the side cylinder 13 pushes the polishing wheel 9 to press against the outer surface of Product 2 for polishing - after completing one round of polishing of Product 2, the side cylinder 13 retracts, the polishing drive motor 10 stops, the clamping cylinder 6 is released, and Product 2 is taken out.

[0029] This technical solution may also include the following technical details to better achieve the technical effect: it also includes a second slide rail mechanism, which includes: a track support 11, a pair of second tracks 12, a side cylinder 13 and a moving plate 14; the track support 11 is installed on the tooling table 1, the pair of second tracks 12 is installed on the track support 11, the moving plate 14 is fixed on the slider of the pair of second slide rails, the side cylinder 13 drives the moving plate 14 to move, so that the grinding wheel 9 approaches or moves away from the product 2, the grinding drive motor 10 is fixed to the moving plate 14 through the seat, and the grinding drive motor 10 drives the grinding wheel 9 to rotate and grind through the transmission mechanism.

[0030] This technical solution may also include the following technical details to better achieve the technical effect: the support plate 4 is installed on the top of the tooling table 1 through the first slide rail 16 mechanism;

[0031] The first slide rail mechanism 16 includes: a track base 15, a pair of slide rails 16, a lead screw 17, and a worktable motor 18. The track base 15 is mounted on the surface of the tooling table 1, the pair of slide rails 16 are mounted on the track base 15, the support plate 4 is fixed on the slider of the pair of slide rails 16, the bottom of the support plate 4 is fixed to the nut of the lead screw 17, the worktable motor 18 drives the lead screw 17 to rotate, and the pair of slide rails 16 are configured to allow the support plate 4 to move closer to or further away from the grinding wheel 9. The track base 15 has a hollow center, allowing the bottom motor 3 to pass through the track base 15. In this embodiment, the product 2 is a non-circular compressor housing, which is often an irregular or elliptical structure. Taking the elliptical product 2 as an example, when the product 2 rotates, the longer end of the product 2 rotates to the grinding wheel 9, causing it to be pressed down. By rotating the worktable motor 18, the support plate 4 is moved back a certain distance, thereby ensuring the normal grinding of the compressor housing.

[0032] This technical solution may also include the following technical details to better achieve the technical effect: In order to ensure that the product 2 rotates more smoothly and to protect the contact surface of the product 2, in a preferred embodiment, the positioning block 8 is a rubber pad, which is installed with the positioning arm 7 through a plane bearing.

[0033] This technical solution may also include the following technical details to better achieve the technical effect: the clamping cylinder 6 is fixed to the support plate 4 by the cylinder seat.
