[0035] The utility model is described in more detail by way of example with reference to the drawings in the following paragraphs. The advantages and features of the utility model will be more apparent from the following description. It should be noted that the drawings are in a very simplified form and are not drawn to precise scale, and are merely used to facilitate and clarify the purpose of assisting in the description of the embodiments of the utility model.

[0036] As shown in the utility model discloses a cylindrical workpiece fixing frock, including base 1, fixed clamp 2 and angle adjusting part 3. Figures 1 to 3

[0037] Specifically, the fixed clamp 2 end rotates and is installed on the base 1, and the fixed clamp 2 is movably connected with the base 1 through the angle adjusting part 3 on the side away from the base 1, and the fixed clamp 2 is used for clamping and fixing the cylindrical workpiece to be processed.

[0038] The angle adjusting part 3 includes support seat 4, adjusting screw rod 5 and worm gear.

[0039] The support seat 4 top is slidably connected with the length direction outer side wall of the fixed clamp 2, and the support seat 4 bottom is slidably connected with the upper surface of the base 1.

[0040] The adjusting screw rod 5 is movably installed on the base 1, and the adjusting screw rod 5 is threadedly connected with the support seat 4.

[0041] The worm gear is movably installed on the base 1, and the worm gear is drivingly connected with the adjusting screw rod 5.

[0042] In the embodiment, the workpiece to be processed is installed on the fixed clamp 2, and after the adjustment of the inclination angle of the fixed clamp 2 is completed, the processing of the workpiece to be processed can be carried out. The adjustment of the inclination angle of the fixed clamp 2 is specifically as follows:

[0043] The worm gear drives the adjusting screw rod 5 to rotate, and the support seat 4 threadedly connected with the adjusting screw rod 5 cannot rotate with the adjusting screw rod 5 due to the limitation of the base 1, so that the support seat 4 can only move along the length direction of the adjusting screw rod 5, and the moving direction of the support seat 4 is controlled by the rotating direction of the worm gear. During the movement of the support seat 4, the inclination angle of the fixed clamp 2 changes as follows:

[0044] When the support seat 4 moves towards the rotating connection between the fixed clamp and the base 1, the end of the fixed clamp 2 away from the rotating connection is lifted. At this time, the inclination angle of the fixed clamp 2 increases.

[0045] When the support seat 4 moves away from the rotating connection between the fixed clamp 2 and the base 1, the end of the fixed clamp 2 away from the rotating connection is lowered. At this time, the inclination angle of the fixed clamp 2 decreases. ​

[0046] Further, the worm gear includes a transmission worm wheel 7 and a driving worm 6;

[0047] The transmission worm wheel 7 is fixedly installed on the adjusting screw rod 5;

[0048] The driving worm 6 is rotatably installed on the base 1, and the driving worm 6 is in meshing connection with the transmission worm wheel 7.

[0049] In the embodiment, the adjusting screw rod 5 is in transmission connection through the worm gear, and the self-locking between the transmission worm wheel 7 and the driving worm 6 can be used to keep the fixed clamp 2 at the adjusted inclination angle, thereby ensuring the stable processing of the workpiece to be processed.

[0050] In order to facilitate the rotation of the driving worm 6, an adjusting handle 15 is installed at the end of the driving worm 6.

[0051] Further, the side surface of the base 1 is provided with an angle scale 14, which is used to measure and indicate the inclination angle of the fixed clamp 2.

[0052] Specifically, as shown in Figure 1 When the angle scale 14 is installed, the center of the angle scale 14 should be located on the extension line of the edge of the bottom surface of the fixed clamp. When the inclination angle is adjusted, the scale line on the angle scale 14 aligned with the edge of the bottom surface of the fixed clamp 2 is the inclination angle θ1 of the fixed clamp. At this time, the processing angle θ2 on the workpiece to be processed is equal to θ1.

[0053] When the inclination angle of the fixed clamp 2 is adjusted, the inclination angle can be adjusted according to the angle indicated on the angle scale 14, so that the accurate adjustment of the inclination angle of the fixed clamp 2 can be quickly completed.

[0054] Further, the fixed clamp 2 includes a support plate 8, a slot-shaped limiting strip 9, a fixed screw rod 10, a fixed nut 11 and a fixed pad 12.

[0055] Specifically, the slot-shaped limiting strip 9 is fixedly installed on the upper surface of the support plate 8.

[0058] The fixed pad 12 is inserted on the fixed screw rod 10, and the fixed pad 12 is fastened by the fixed nut 11 and clamps and fixes the cylindrical workpiece to be processed.

[0059] In the embodiment, when the cylindrical workpiece needs to be fixed on the fixing clamp 2, first, the fixing nut 11 on the fixing screw 10 is loosened. Then, the fixing pad 12 is removed, and the cylindrical workpiece is placed on the groove limiting strip 9. Finally, the fixing pad 12 is inserted into the fixing screw 10, and the fixing nut 11 is tightened, and the fixing operation of the cylindrical workpiece is completed.

[0060] In an embodiment, a plurality of groove limiting strips 9 are provided, and the plurality of groove limiting strips 9 are uniformly distributed on the support plate 8. Meanwhile, the groove limiting strip 9 is provided with an arc-shaped positioning groove 13 matched with the cylindrical workpiece to be processed.

[0061] For example, in the embodiment, two groove limiting strips 9 are used, and are respectively fixedly installed on the support plate 8 near one end close to the base 1 and one end away from the base 1. Meanwhile, as shown in the figure, the fixing screw 10 is also provided with a flat portion, which is used for better cooperation with the limiting strip 9 to fix the workpiece to be processed. Figure 4

[0062] In addition, as shown in the figure, the end of the fixing pad 12 is provided with a quick-release groove 16 matched with the fixing screw 10.
