[0028] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0029] Reference Figure 1 and Figure 2 In one embodiment of this utility model, the workpiece carrier fixture includes a rotating shaft 1, a positioning element 2, and a clamping assembly 3. The rotating shaft 1 can be driven to rotate around its axis; the positioning element 2 is fixedly installed on the end face of the rotating shaft 1, and the side of the positioning element 2 away from the rotating shaft 1 is used to abut against the workpiece to be processed; the clamping assembly 3 is installed in cooperation with the positioning element 2 and is used to clamp and fix the workpiece on the positioning element 2. In this embodiment, the rotating shaft 1 is driven to rotate under the action of an external power source, which can drive the workpiece fixed by the positioning element 2 and the clamping assembly 3 to rotate, thereby completing the corresponding processing steps of the workpiece. The workpiece involved in this embodiment is described in [reference needed]. Figure 1 .

[0030] Reference Figure 2 and Figure 3The positioning component 2 includes a positioning strip 21 fixedly mounted on the end face of the rotating shaft 1, and a slider 22 slidably mounted on one end of the positioning strip 21. The slider 22 slides along the extension direction of the positioning strip 21 and is used to abut against the workpiece. Therefore, when fixing the workpiece to the positioning strip 21, one side of the workpiece is first abutted against the side of the positioning strip 21 away from the rotating shaft 1, and then the slider 22 abuts against the side of the workpiece. Thus, the position of the workpiece on the positioning strip 21 can be adjusted to complete the positioning of the workpiece. After positioning, the workpiece is clamped and fixed in conjunction with the clamping assembly 3.

[0031] Specifically, refer to Figure 2 and Figure 3 In this embodiment, the workpiece carrier fixture also includes a fastener 4. The slider 22 has an elongated hole 221, the extension direction of which is the same as the sliding direction of the slider 22. A mounting hole (not shown in the figure) is provided at a corresponding position on the positioning strip 21. The fastener 4 passes through the mounting hole and the elongated hole 221 to limit and fix the slider 22 to a preset position on the positioning strip 21. In this embodiment, the fastener 4 can be a pin or screw, etc. The elongated hole 221 facilitates adjustment of the preset position of the slider 22 on the positioning strip 21. The preset position refers to the position where the workpiece is mounted on the positioning strip 21 for subsequent milling or punching.

[0032] In this embodiment, refer to Figure 2 and Figure 3 The length of the positioning strip 21 is equal to the diameter of the rotating shaft 1, and the vertical projection of the positioning strip 21 onto the end face of the rotating shaft 1 passes through the center of the circle containing the end face of the rotating shaft 1. As the rotating shaft 1 rotates at high speed, the positioning strip 21 is positioned to effectively maintain the balance of rotation and reduce the vibration that may be generated during the high-speed rotation of the rotating shaft 1. Reducing vibration can further ensure the machining accuracy of the workpiece.

[0033] Reference Figure 2 and Figure 3 In this embodiment, the positioning component 2 further includes a disc 23, which is fixedly connected to the side of the positioning strip 21 away from the slider 22. The disc 23 is coaxially arranged with the end face of the rotating shaft 1, and the disc 23 is fixedly connected to the rotating shaft 1. The disc 23 facilitates the connection between the positioning strip 21 and the rotating shaft 1.

[0034] Reference Figure 2 and Figure 3 On the one hand, the slider 22 needs to abut against the positioning workpiece; on the other hand, in this embodiment, the workpiece is mainly installed on the half of the positioning strip 21 where the slider 22 is located, which causes the rotating shaft 1 to become unbalanced when driving the workpiece to rotate, resulting in a certain vibration. Therefore, a counterweight is provided at the end of the positioning strip 21 away from the slider 22. The counterweight is used to balance the eccentric force borne by the rotating shaft 1 when it rotates.

[0035] Specifically, refer to Figure 2 and Figure 3 The positioning strip 21 has multiple spaced fixing holes 211 at the end away from the slider 22. The straight line connecting the multiple fixing holes 211 is in the same direction as the extension direction of the positioning strip 21. The counterweight is detachably installed on the positioning strip 21 through the fixing holes 211. By fixing counterweights of different weights in different fixing holes 211, the eccentric force of the rotating shaft 1 can be effectively balanced, thereby ensuring the balance of the rotating shaft 1.

[0036] Reference Figure 2 and Figure 3 The clamping assembly 3 includes two clamping blocks 31, which are mirror images of the positioning strip 21 with symmetry as the axis of rotation. The two clamping blocks 31 can be driven to move closer to or further away from each other. When the two clamping blocks 31 are driven to move closer to each other to a first position, the clamping blocks 31 abut against the workpiece. In this embodiment, the clamping assembly 3 can be a hydraulic clamping device. After the workpiece is placed at the corresponding position on the positioning strip 21, driving the two clamping blocks 31 closer together effectively abuts and clamps the workpiece.

[0037] Understandably, the two clamping blocks 31 can also be driven to move in a direction away from each other to a second position. When the two clamping blocks 31 are in the second position, they are mainly used for picking up and placing workpieces on the positioning strip 21.

[0038] To further ensure the balance of the rotation of the shaft 1, the straight line on which the vertical projection of the two clamping blocks 31 on the end face of the shaft 1 lies passes through the center of the circle on the end face of the shaft 1.

[0039] Reference Figure 3 In this embodiment, the preset distance between the clamping block 31 and the rotating shaft 1 is greater than the preset distance between the positioning strip 21 and the rotating shaft 1. The preset distance is the distance between the side of the clamping block 31 or the positioning strip 21 away from the rotating shaft 1 and the end face of the rotating shaft 1. By setting the preset distance between the clamping block 31 and the positioning strip 21 and the rotating shaft 1, the contact area between the clamping block 31 and the workpiece can be increased, thereby ensuring the effectiveness of the clamping block 31 in clamping and fixing the workpiece as much as possible, and thus ensuring subsequent processing.

[0040] The implementation principle of the workpiece carrier fixture in this embodiment is as follows: First, drive the two clamping blocks 31 away from each other. Then, adjust the slider 22 to a preset position. Next, place the workpiece on one side of the positioning strip 21, making the end face of the workpiece abut against the slider 22. Finally, bring the two clamping blocks 31 closer together to abut and fix the workpiece. After fixing, a counterweight is set on the other side of the positioning strip 21 according to the weight and position of the slider 22 and the workpiece. Finally, drive the rotating shaft 1 to rotate, and use external punching and milling tools to complete the processing of the workpiece.
