In order to improve processing efficiency, the processing path of the robot arm is mostly a fixed path, that is, it drives the laser component to process the upper end surface of the workpiece 1 according to the set moving path. For this reason, it is necessary to manually place the workpieces 1 on the positioning plate 2 (such as Figure 9 As shown in FIG, in order to accurately place the workpiece 1 on the positioning plate 2 to position the workpiece 1, the prior art generally adopts the following two positioning methods, such as Figure 9 As shown in the upper part, it is easy for workers to identify by marking a positioning mark 21 on the positioning plate 2, so as to place the workpiece 1 at the center of the positioning mark 21, thereby achieving the positioning of the workpiece 1; another positioning method, such as Figure 9 As shown in the lower part, the workpiece 1 is positioned by providing a positioning plate groove 22 on the positioning plate 2 that matches the size of the workpiece 1 , that is, the workpiece 1 is placed in the positioning plate groove 22 .

[0003] The above positioning method has the following technical problems: since the inner diameter of the positioning plate groove 22 is fixed, when positioning and processing small batches of multi-sized workpieces 1, the positioning plates 2 with different sizes of positioning plate grooves 22 need to be replaced, which leads to an increase in the overall equipment cost and a decrease in the overall processing efficiency; although the positioning mark 21 can be used to position different workpieces 1, when the workpiece 1 is placed, the positioning mark 21 will be pressed, resulting in a decrease in the positioning accuracy of the workpiece 1 and a low positioning efficiency.

Therefore, they cannot be understood as limitations on the present invention. Example

[0029] See attached Figure 1 、 2 As shown, an adjustable positioning tray includes a tray 3, on which a positioning disc 4 is rotatably provided. In order to guide the positioning disc 4 during rotation, a circular tray groove 31 is provided on the upper end surface of the tray 3, and the positioning disc 4 is rotatably embedded in the tray groove 31.

[0030] See also Figure 4 As shown, in order to lock the positioning disc 4 in the tray groove 31 , a rotation through hole 41 is opened at the center of the positioning disc 4 , and the fastening bolt 5 can be rotatably passed through the rotation through hole 41 and threadedly connected to the tray 3 .

[0031] See also Figure 7 、 8 As shown, further, in order to facilitate locking the positioning plate 4 on the material tray 3 by the fastening bolt 5, a threaded sleeve 6 is fixedly embedded in the bottom of the material tray groove 31 of the material tray 3, and the screw 51 of the fastening bolt 5 can be threadedly connected in the threaded sleeve 6.

[0032] Furthermore, in order to guide the positioning disk 4 when the positioning disk 4 rotates with the screw of the fastening bolt 5 as the axis, a guide sleeve 42 is integrally formed and vertically fixedly connected to the lower end face of the positioning disk 4. The guide sleeve 42 is arranged above the threaded sleeve 6. When the fastening bolt 5 locks the positioning disk 4, a gap is left between the lower end face of the guide sleeve 42 and the upper end face of the threaded sleeve 6, and the guide sleeve 42 can be rotatably passed through the material tray 3.

[0033] See also Figure 4 、 5As shown, in order to avoid interference between the nut of the fastening bolt 5 and the lower end surface of the workpiece 1 when the workpiece 1 is placed on the positioning plate 4, in this embodiment, a countersunk hole 43 is opened on the upper end surface of the center of the positioning plate 4. The countersunk hole 43 is coaxial with the rotating through hole 41 and is connected to each other. The fastening bolt 5 is successively inserted into the countersunk hole 43 and the rotating through hole 41 and then threadedly connected to the threaded sleeve 6; when the fastening bolt 5 locks the positioning plate 4, the nut 52 of the fastening bolt 5 is completely embedded in the countersunk hole 43, that is, the upper end surface of the nut 52 is below the upper end surface of the positioning plate 4.

[0034] A plurality of arcuate guide grooves 44 are evenly distributed on the positioning plate 4, centered around the rotation hole 41. The guide grooves 44 extend through the positioning plate 4, and the centers of the plurality of guide grooves 44 lie on a common circle centered around the axis of the rotation hole 41. In this embodiment, four guide grooves 44 are provided, but three may also be provided.

[0035] See also Figure 1 、 3 As shown, a number of slide grooves 32 matching the number of guide grooves 44 is provided on the material tray 3. Specifically, in this embodiment, a cross-shaped slide groove 32 is provided at the bottom of the groove 31 of the material tray, and the middle parts of the slide grooves 32 are connected to form four slide grooves 32. The guide sleeve 42 can be rotatably passed through the middle connecting part of the slide groove 32.

[0036] See also Figure 6 As shown, a slider 7 is slidably embedded in each chute 32, that is, four sliders 7 are slidably embedded. A positioning post 8 is fixedly connected to the upper end surface of the slider 7. The slider 7 and the positioning post 8 can be integrally formed or connected by other means, such as a threaded connection. The slider 7 is completely embedded in the chute 32, and the positioning post 8 is respectively inserted into the corresponding guide groove 44 and extends above the positioning plate 4.

[0037] When the fastening bolts 5 do not lock the positioning disk 4 and the positioning disk 4 rotates, the positioning posts 8 slide in the guide grooves 44 and the slider 7 slides in the slide grooves 32, thereby changing the internal space between the positioning posts 8 by causing the positioning posts 8 to move toward or away from each other, thereby positioning cylindrical workpieces 1 of different specifications and sizes.

[0038] To facilitate placement of the workpiece 1 between the four positioning posts 8, the upper ends of the positioning posts 8 are conical. Furthermore, to prevent the positioning posts 8 from scratching the surface of the workpiece 1 when placing or removing the workpiece 1, anti-scratch rubber sleeves (not shown) are provided on the positioning posts 8.

[0039] To facilitate batch loading and positioning of workpieces 1, the tray 3 is provided with multiple sets of corresponding tray grooves 31, chutes 32, sliders 7, positioning posts 8, positioning discs 4, fastening bolts 5, and threaded sleeves 6. In this embodiment, nine tray grooves 31 are evenly distributed on the tray 3. A threaded sleeve 6 is fixedly embedded in the bottom of each tray groove 31. A set of positioning discs 4 and corresponding fastening bolts 5 are disposed within each tray groove 31. Four chutes 32 are provided at the bottom of each tray groove 31, and each chute 32 corresponds to a slider 7 and positioning post 8.

[0040] The working process of the embodiment of the utility model is as follows:

[0041] Adjust the internal space between each positioning column 8 according to the size of the workpiece 1 to be positioned, that is, loosen the fastening bolt 5, and rotate the positioning plate 4 forward or reverse according to the size of the workpiece 1 to make the positioning columns 8 move toward or away from each other. When the space between each positioning column 8 is adapted to the outer diameter of the workpiece 1, tighten the fastening bolt 5 to fix the positioning plate 4 on the material tray 3. At this time, the space and distance between each positioning column 8 are fixed. Before processing the workpiece 1, it is only necessary to manually place the workpiece 1 between each group of positioning columns 8.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
