Detailed Description
The following description of the present utility model will be made in more detail with reference to the schematic drawings, in which preferred embodiments of the present utility model are shown, it being understood that the person skilled in the art may modify the present utility model described herein while still achieving the advantageous effects of the present utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.
The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. The advantages and features of the present utility model will become more apparent from the following description. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.
As shown in fig. 1 to 3, the utility model discloses a cylindrical workpiece fixing tool, which comprises a base 1, a fixing clamp 2 and an angle adjusting piece 3.
Specifically, the end part of the fixed clamp 2 is rotatably installed on the base 1, one side, away from the base 1, of the fixed clamp 2 is movably connected with the base 1 through the angle adjusting piece 3, and the fixed clamp 2 is used for clamping and fixing a cylindrical workpiece to be processed.
The angle adjusting piece 3 comprises a supporting seat 4, an adjusting screw rod 5 and a worm gear.
The top of the supporting seat 4 is in sliding connection with the outer side wall of the fixing clamp 2 in the length direction, and the bottom of the supporting seat 4 is in sliding connection with the upper surface of the base 1.
The adjusting screw rod 5 is movably mounted on the base 1, and the adjusting screw rod 5 is in threaded connection with the supporting seat 4.
The worm gear is movably mounted on the base 1, and is in transmission connection with the adjusting screw rod 5.
In this embodiment, the workpiece to be machined is mounted on the fixing jig 2, and after the adjustment of the inclination angle of the fixing jig 2 is completed, machining of the workpiece to be machined can be performed instead. Wherein, the adjustment of the inclination angle of the fixed clamp 2 is specifically:
The adjusting screw rod 5 is driven to rotate by the worm and gear, the supporting seat 4 in threaded connection with the adjusting screw rod 5 cannot rotate along with the adjusting screw rod 5 due to the fact that the supporting seat 4 is limited by the base 1, the supporting seat 4 can only move along the length direction of the adjusting screw rod 5, and the moving direction of the supporting seat 4 is controlled by the rotating direction of the worm and gear. During the movement of the support base 4, the inclination angle of the fixing jig 2 is changed to:
When the support seat 4 moves in the direction approaching to the rotation connection position of the fixing clamp and the base 1, one end of the fixing clamp 2 away from the rotation connection position is lifted. At this time, the inclination angle of the fixing jig 2 increases.
When the support base 4 moves in a direction away from the rotational connection of the fixing clamp 2 and the base 1, one end of the fixing clamp 2 away from the rotational connection is lowered. At this time, the inclination angle of the fixing jig 2 is reduced.
Further, the worm gear comprises a transmission worm wheel 7 and a driving worm 6;
The transmission worm wheel 7 is fixedly arranged on the adjusting screw rod 5;
the driving worm 6 is rotatably mounted on the base 1, and the driving worm 6 is in meshed connection with the transmission worm wheel 7.
In the embodiment, the adjusting screw rod 5 is in transmission connection through the worm and gear, and the fixing clamp 2 can be kept at an adjusted inclined angle by utilizing self-locking between the transmission worm wheel 7 and the driving worm 6, so that stable machining of a workpiece to be machined is ensured.
For facilitating the rotation of the drive worm 6, an adjusting handle 15 is mounted at the end of the drive worm 6.
Further, the side surface of the base 1 is provided with an angle dial 14, and the angle dial 14 is used for measuring and indicating the inclination angle of the fixing clamp 2.
Specifically, as shown in fig. 1, when the angle dial 14 is installed, the center of the angle dial 14 should be located on the extension line of the bottom edge of the fixing clamp. When the inclination angle is adjusted, the scale mark aligned on the bottom edge of the fixed clamp 2 and the angle dial 14 is the inclination angle theta 1 of the fixed clamp. At this time, the machining angle θ2 on the workpiece to be machined is equal to θ1.
When the inclination angle of the fixing clamp 2 is adjusted, the inclination angle can be adjusted according to the angle indicated on the angle dial 14, so that the accurate adjustment of the inclination angle of the fixing clamp 2 can be completed quickly.
Further, the fixing clamp 2 comprises a supporting plate 8, a groove-type limiting strip 9, a fixing screw 10, a fixing nut 11 and a fixing cushion block 12.

In the present embodiment, when it is necessary to fix the cylindrical workpiece to the fixing jig 2, first, the fixing nut 11 on the fixing screw 10 is unscrewed. Then, the fixed pad 12 is removed and the cylindrical workpiece is placed on the groove-shaped stopper 9. Finally, the fixing spacer 12 is inserted into the fixing screw 10, and the fixing nut 11 is tightened to complete the fixing operation of the cylindrical workpiece.
In a specific embodiment, a plurality of groove-shaped limiting strips 9 are provided, and the groove-shaped limiting strips 9 are uniformly distributed on the supporting plate 8. Meanwhile, an arc-shaped positioning groove 13 matched with the cylindrical workpiece to be processed is formed in the groove-shaped limiting strip 9.
For example, in the present embodiment, two groove-shaped limiting bars 9 are employed, which are fixedly installed at one end of the support plate 8 near the base 1 and one end far from the base 1, respectively. Meanwhile, as shown in fig. 4, a plane part is also arranged on the fixing screw 10, so as to better match with the limit strip 9 to fix the workpiece to be processed.
In addition, as shown in fig. 5, the end of the fixed pad 12 is provided with a quick-release groove 16 matching with the fixed screw 10. When the cylindrical workpiece is fixed, the fixed cushion block 12 is sleeved on the fixed screw rod 10 through a quick-release groove on the fixed cushion block, and the fixed nut 11 is screwed, so that the fixed nut 11 can firmly compress the fixed cushion block 12 on the workpiece.
