For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] As Figures 1-3 shown, a workpiece positioning tooling proposed by the present utility model includes a bottom plate 1 and a limiting rod 3. A support assembly is provided at the upper end of the bottom plate 1. The limiting rod 3 is vertically arranged. The limiting rod 3 is located above the support assembly, and its bottom end passes through the support assembly and is connected to the bottom plate 1. The inner wall of the limiting rod 3 is arranged in contact with the inner end face of the workpiece. A limiting assembly is detachably provided at the upper end of the limiting rod 3. A positioning assembly for positioning the workpiece is provided at the upper end of the bottom plate 1.

[0023] In the present utility model, when the device needs to be used, the workpiece to be processed is sleeved on the limiting rod 3. When installing the workpiece, the angle of the workpiece is adjusted, and the positioning and preliminary limiting of the workpiece are completed through the positioning component. The workpiece is supported by the supporting component. After the workpiece is positioned and placed on the placing component, the limiting component completes the limiting of the workpiece in the vertical direction, so as to cooperate with the positioning component to complete the installation and fixation of the workpiece, thereby effectively facilitating the processing of the workpiece. Since the limiting component is detachably arranged, when the workpiece needs to be unloaded after processing, only the limiting component needs to be disassembled, and the workpiece can be taken out from the upper end. The device can effectively fix the workpiece, thereby improving the stability of the device during processing. When the device fixes the workpiece, the positioning component can preliminarily position the workpiece and then complete the limiting of the workpiece, thereby effectively improving the limiting accuracy of the workpiece.

[0024] In an alternative embodiment, the positioning component includes a plurality of clamping blocks 5. The plurality of clamping blocks 5 are all arranged on the bottom plate 1. One end of each of the plurality of clamping blocks 5 facing the limiting rod 3 is provided with a first notch for accommodating the workpiece. The inner wall of the first notch is arranged in contact with the outer end of the workpiece. The bottom end of the first notch and the upper end of the supporting component are located on the same horizontal line. Through the first notches provided on the plurality of clamping blocks 5, when loading the workpiece, the workpiece is moved on the limiting rod 3 to the first notches according to the positions of the plurality of first notches. By the inner wall of the first notch being in contact with the outer end of the workpiece, the positioning of the workpiece is effectively completed, and the limiting of the workpiece in the horizontal angle is completed, thereby completing the preliminary limiting of the workpiece.

[0025] In an alternative embodiment, the supporting component includes a supporting disk 4. The supporting disk 4 is coaxially arranged with the limiting rod 3 and is connected to the bottom plate 1. The supporting disk 4 is provided with a first through hole for the limiting rod 3 to pass through. The upper end of the supporting disk 4 and the bottom end of the first notch are located on the same horizontal line. The supporting of the workpiece can be effectively completed through the supporting disk 4. And for the flatness of the workpiece placement, the staff only needs to clean the supporting disk 4 during cleaning, effectively reducing the work intensity of the staff.

[0026] In an optional embodiment, the support assembly includes a plurality of support rods 12, and the plurality of support rods 12 are vertically arranged on the base plate 1, and the plurality of support rods 12 are evenly distributed along the circumference of the center of the circle of the limit rod 3, and the upper ends of the plurality of support rods 12 are respectively located on the same horizontal line as the bottom ends of the plurality of first notches. The plurality of support rods 12 are evenly distributed on the base plate 1 to effectively support the workpiece, and the upper ends of the plurality of support rods 12 do not contact the limit rod 3, so that when the staff needs to clean the upper end surface of the support rod 12, it will not be blocked by the limit rod 3, and only needs to fall off the impurities on it, thereby reducing the work intensity of the staff when cleaning the support rod 12 to ensure the flatness of the support.

[0027] In an optional embodiment, the limiting assembly includes a limiting plate 6, a threaded rod 7 and a handle 8. The top of the limiting rod 3 is provided with a first threaded blind hole. The limiting plate 6 is located above the limiting rod 3 and is coaxially arranged therewith. The limiting plate 6 is provided with a second through hole. A threaded rod 7 is rotatably arranged in the second through hole. The top of the threaded rod 7 extends out of the second through hole and is coaxially provided with a handle 8. The bottom end of the threaded rod 7 extends out of the second through hole and extends into the first threaded blind hole. The threaded rod 7 is threadedly connected to the limiting rod 3. When it is necessary to limit the workpiece, the workpiece is sleeved on the limiting rod 3 so that the workpiece can be positioned. The bottom end of the workpiece abuts against the upper section of the supporting assembly to limit the bottom of the workpiece, the limiting plate 6 is placed above the workpiece, and the threaded rod 7 is inserted into the first threaded blind hole. By rotating the threaded rod 7, the threaded rod 7 moves downward when rotating, driving the limiting plate 6 rotatably connected thereto to move downward. The limiting plate 6 abuts against the upper end of the workpiece when moving downward, thereby cooperating with the supporting assembly to limit the workpiece. The device is very convenient for limiting the workpiece, and when unloading, it is only necessary to rotate the threaded rod 7 to disengage it from the first threaded blind hole. When the threaded rod 7 disengages from the first threaded blind hole, the limiting plate 6 will not affect the loading and unloading operations of the workpiece.

[0028] In an alternative embodiment, it further includes a base 2, a motor 9, a slider 10, and a screw 11. The base 2 is located below the bottom plate 1. The bottom plate 1 is slidably connected to the base 2. A chute is provided at the upper end of the base 2. The slider 10 is slidably disposed in the chute. The slider 10 is connected to the bottom plate 1. A first threaded through hole is provided on the slider 10. The screw 11 is threadedly disposed in the first threaded through hole. One end thereof passes through the chute and is coaxially connected to the output shaft of the motor 9, and the other end is rotatably connected to the inner wall of the chute. The motor 9 is connected to the base 2. During use, the motor 9 drives the screw 11 to rotate. The rotation of the screw 11 drives the slider 10 threadedly connected thereto to move. The movement of the slider 10 can effectively drive the bottom plate 1 to slide. When the bottom plate 1 slides, it can drive the workpiece thereon to move out of the processing position. When the workpiece moves out of the processing position, it is more convenient for the staff to load the workpiece. Moreover, the working area of the staff is not located within the processing position, which can effectively improve the safety of the staff during work.

[0029] It should be understood that the above specific embodiments of the present invention are only for illustrative or explanatory purposes of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
