DETAILED DESCRIPTION

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a gantry milling machine processing fixture, comprising:

[0021] A mounting plate 1, wherein four bolt holes 2 are formed on the mounting plate 1, and the four bolt holes 2 are distributed in a circular array on the mounting plate 1. The mounting plate 1 can be mounted on a workbench by passing bolts through the bolt holes 2;

[0022] A fixture assembly for clamping a cylindrical workpiece; the fixture assembly includes a fixed plate 6 fixed on a mounting plate 1, the fixed plate 6 is provided with three T-slots 10, the three T-slots 10 are distributed in a ring array, a T-block 11 capable of being reset is slidably connected in the T-slot 10, a spring 12 is fixed on the T-block 11, the other end of the spring 12 is fixedly connected to the inner wall of the T-slot 10, and the spring 12 is used to reset the T-block 11;

[0023] A movable plate 13 is fixed on the T-block 11, and a reinforcing rib is fixed between the movable plate 13 and the T-block 11, which can increase the stability of the installation of the movable plate 13; a T-clamping plate 14 that can be replaced for different cylindrical workpieces is provided on the movable plate 13, and a T-mounting groove 16 arranged along the axial direction of the mounting plate 1 is provided on the movable plate 13, and a rubber film is provided on the outer wall of the T-clamping plate 14, and the T-clamping plate 14 slides in the T-mounting groove 16, and the rubber film is against the inner wall of the T-mounting groove 16, and the friction force of the rubber film is used to install the T-clamping plate 14 in the T-mounting groove 16, and bolts can also be installed on the movable plate 13, and the T-clamping plate 14 can be positioned by the bolts;

[0024] A driving ring 7 is rotatably connected to the fixed disk 6, and an arc groove 9 is provided on the driving ring 7 for use with the moving plate 13. The side of the moving plate 13 that abuts against the arc groove 9 is in an arc shape. The driving ring 7 rotates to cooperate with the arc groove 9 to achieve tightening of the moving plate 13; wherein, a mounting block 3 is fixed to the mounting disk 1, a motor 4 is fixed to the mounting block 3, a worm 5 is fixed to the output end of the motor 4, a worm wheel 8 is fixed to the driving ring 7, and the worm 5 is meshed with the worm wheel 8;

[0025] Further explanation: the motor 4 drives the worm 5 to rotate, and the rotation of the worm 5 drives the worm wheel 8 and the driving ring 7 to rotate. At this time, the arc groove 9 squeezes the movable plate 13 to tighten it, and finally makes the arc surface 15 on the T-shaped clamping plate 14 abut against the cylindrical workpiece, so as to achieve stable clamping of the cylindrical workpiece; when the motor 4 is turned over, the arc groove 9 no longer limits the movable plate 13, and under the action of the spring 12, the T-block 11 and the movable plate 13 can be reset to remove the cylindrical workpiece;

[0026] Due to the different diameters of the cylinder, the T-shaped clamping plate 14 is provided with an arcuate surface 15 that fits the cylindrical workpiece, and the contact area between the arcuate surface 15 and the outer wall of the cylindrical workpiece is also different. Therefore, T-shaped clamping plates 14 with different arcuate surfaces 15 can be selected for different types of cylindrical workpieces, thereby increasing the clamping area of ​​the cylindrical workpiece and clamping it more stably. At this time, the T-shaped clamping plate 14 and the arcuate surface 15 are not for all cylindrical workpieces, and can produce the sizes of cylindrical workpieces commonly processed in the factory.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
