[0030] Example 1

[0031] Reference Figure 1 and 3 A chamfering fixture includes a base 101 and a support column 102. Two support plates 103 are symmetrically arranged on the base 101. A bidirectional screw rod 115 is installed inside the base 101. The bidirectional screw rod 115 is driven by a transmission motor 114 on the side of the base 101. Two moving seats 116 are installed on the bidirectional screw rod 115. The two moving seats 116 are fixedly connected to the two support plates 103 respectively, so that the bidirectional screw rod 115 can drive the support plates 103 to move.

[0032] Reference Figure 2An adjusting motor 104 is installed on one of the support plates 103, a rotating shaft 105 is provided at the output end of the adjusting motor 104, and a rotating disk 106 is installed on the rotating shaft 105; an adjusting telescopic rod 107 is provided on the other support plate 103, and a fixed disk 108 is installed at the movable end of the adjusting telescopic rod 107. When the support plate 103 is driven close to the center of the base 101 by the two-way screw rod 115, the fixed disk 108 and the rotating disk 106 both abut against the workpiece to clamp the workpiece. At this time, the rotating disk 106 is driven to rotate by the adjusting motor 104, and the workpiece is driven to rotate along the fixed disk 108, thereby realizing the adjustment of the workpiece angle.

[0033] Furthermore, in order to prevent the workpiece from moving during the angle adjustment process, the present embodiment installs a plurality of friction strips on the rotating disk 106 and the fixed disk 108. The friction strips can increase the friction force between the contact surfaces of the rotating disk 106 and the fixed disk 108 and the workpiece to ensure tight clamping.

[0034] Furthermore, the adjustable telescopic rod 107 is a telescopic sleeve rod. In order to prevent the fixed plate 108 from retreating too long when the adjustable telescopic rod 107 contacts the workpiece, an adjusting spring 109 is arranged between the adjustable telescopic rod 107 and the fixed plate 108. One end of the adjusting spring 109 abuts against the retreat groove on the adjustable telescopic rod 107, and the other end abuts against the fixed plate 108, so that an elastic connection is formed between the adjustable telescopic rod 107 and the fixed plate 108, thereby limiting the retreat distance of the adjustable telescopic rod 107, and the adjusting spring 109 can also provide a buffer when the fixed plate 108 clamps the workpiece.

[0035] Preferably, a fixed cylinder 111 and two pneumatic telescopic rods 112 are installed at one end of the support plate 103 away from the center of the base 101. The two pneumatic telescopic rods 112 pass through the support plate 103 and are connected to the fixed plate 113. When the workpiece is fixed, the support plate 103 is driven to move toward the center of the base 101 by the bidirectional screw rod 115, and at the same time, the fixed cylinder 111 and the pneumatic telescopic rod 112 are driven to move toward the center of the base 101, and the movement is stopped when the rotating disk 106 and the fixed disk 108 contact the workpiece. At this time, the pneumatic telescopic rod 112 is pushed to extend by the fixed cylinder 111, and at the same time, the fixed plate 113 is driven to continue to move toward the center of the base 101, and the workpiece is locked between the fixed plates 113 by the fixed plates 113 on both sides, instead of being locked by the rotating disk 106 and the fixed disk 108, so as to prevent the rotating disk 106 and the fixed disk 108 from forming a long-term rigid contact with the workpiece and avoid damage to the rotating shaft 105 and the adjustable telescopic rod 107.

[0036] Example 2

[0037] Reference Figure 4, this embodiment is a fixture for chamfering, which is different from the embodiment 1 in that a buffer plate 202, a buffer telescopic rod 201 and a buffer spring 203 are further provided in this embodiment;

[0038] Among them, the buffer plate 202 is located on the side of the buffer telescopic rod 201 away from the fixed plate 113, the number of the buffer springs 203 is multiple, the buffer springs 203 are respectively fixedly connected to the buffer plate 202 and are respectively located between the buffer plate 202 and the buffer telescopic rod 201, the buffer telescopic rod 201 is a telescopic sleeve rod, and the buffer spring 203 provides support for the buffer telescopic rod 201. When the workpiece is fixed, the fixed plate 113 drives the buffer telescopic rod 201 and the buffer plate 202 to move, and the buffer plate 202 directly contacts the workpiece, thereby avoiding a hard connection between the fixed plate 113 and the workpiece, and preventing damage to the workpiece and the device.
