Specific embodiments

[0024] In order to clearly and completely describe the purpose, technical solution of the present utility model, and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.

[0025] Embodiment 1: Please refer to Figures 1-6 , the present utility model provides a technical solution: A workpiece fixture for a horizontal machining center, comprising: a mounting plate 1, a support frame 2 is provided on the surface of the mounting plate 1, a first bearing 3 is provided on the side of the support frame 2, a support screw 4 is provided inside the first bearing 3, and a moving plate 5 is inserted into the support frame 2; a bottom plate 6, a positioning rod 7 is provided inside the bottom plate 6, a base 8 is provided on the side of the bottom plate 6, a limiting rod 9 is provided at the bottom of the base 8, and a positioning port 10 is provided on the side of the limiting rod 9; a bearing plate 11, a positioning plate 13 is connected to the surface of the bearing plate 11 by a fixing bolt 12;

[0026] When it is necessary to fix the workpiece to facilitate subsequent machining by the horizontal machining center, first place the workpiece on the surface of the support frame 2, and then rotate the support screw 4 to drive the moving plate 5 to displace, and then drive the positioning plate 13 to clamp and position the workpiece. When it is necessary to remove the positioning plate 13, pull the positioning rod 7 to make the positioning rod 7 disengage from the positioning port 10, so that the limiting rod 9 loses its limit, and it is convenient to remove the bottom plate 6 to facilitate the inspection of the positioning plate 13.

[0027] Embodiment 2: On the basis of Embodiment 1, in order to facilitate the positioning of the workpiece, a positioning plate 13 is provided. The support frame 2 is fixedly connected to the surface of the mounting plate 1. One end of the support screw 4 is fixedly connected to the inner ring surface of the first bearing 3. The moving plate 5 is integrally in the shape of a "C"-shaped plate structure. The moving plate 5 is slidably connected inside the support frame 2, and the moving plate 5 is screwed onto the support screw 4;

[0028] In use, the first bearing 3 can be used to rotate the support screw 4, which allows the moving plate 5 screwed onto the support screw 4 to slide within the support frame 2. This allows the positioning plate 13 to be pushed to facilitate clamping and positioning of the workpiece, thus avoiding the problem of workpiece offset during machining by the horizontal machining center. The positioning plate 13 has an overall "V" shaped plate structure, which facilitates the machining and fixing of arc-shaped workpieces.

[0029] An auxiliary plate 18 is provided to facilitate the positioning of the square workpiece. The positioning plate 13 is fixed to the side of the bearing plate 11 by the fixing bolts 12. The positioning plate 13 has a "V" shaped plate structure. A positioning slot 17 is provided on the inner side of the positioning plate 13. The auxiliary plate 18 is inserted into the positioning slot 17. The auxiliary plate 18 has a square plate structure. A connecting plate 19 is provided on the side of the auxiliary plate 18. The connecting plate 19 is sleeved on the fixing bolts 12.

[0030] First, the fixing bolt 12 can be rotated out, and then the auxiliary plate 18 can be inserted into the positioning slot 17. Then, one end of the fixing bolt 12 is passed through the connecting plate 19, so that the auxiliary plate 18 can be easily fixed. The square workpiece can be clamped and fixed in conjunction with the square plate structure auxiliary plate 18.

[0031] Example 3: Based on Example 2, a positioning rod 7 is provided to facilitate the removal of the movable plate 5. A placement groove 14 is provided at the bottom of the base plate 6. A return spring 15 and a pull plate 16 are provided in the placement groove 14. One end of the return spring 15 is fixedly connected to the side of the placement groove 14, and the other end of the return spring 15 is fixedly connected to the inner side of the pull plate 16. The positioning rod 7 is fixedly connected to the outer side of the pull plate 16. The limiting rod 9 passes through the movable plate 5. One end of the positioning rod 7 is inserted into the positioning port 10. The bearing plate 11 is fixedly connected to the side of the base plate 6.

[0032] In use, first pull the pull plate 16 to move the positioning rod 7 backward, so that one end of the positioning rod 7 is disengaged from the positioning port 10, thereby freeing the positioning rod 7 from limiting the limit rod 9, making it easy to remove the base plate 6. Then reverse the support screw 4 to move the moving plate 5 outward, so that the moving plate 5 is disengaged from the support screw 4, making it easy to remove the moving plate 5 and the base plate 6. The reset spring 15 is designed to allow the positioning rod 7 to automatically reset after pulling the pull plate 16, and also to limit the positioning rod 7.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
