[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example: Please refer to Figures 1-6 A mechanical equipment fixture includes a base 7. A first mounting bracket 2 is mounted on one side of the top of the base 7, and a limit plate 5 is provided on one side of the first mounting bracket 2. A drive assembly for driving the limit plate 5 to translate and rotate is provided on one side of the limit plate 5. A second mounting bracket 15 is mounted on the other side of the top of the base 7, and two slots 13 are formed on one side of the second mounting bracket 15. The top of each slot 13 extends above the second mounting bracket 15. A rotating support rod 12 is mounted between the front and rear ends of each slot 13 via a rotating shaft. A fixing cylinder is fixed to the top of each rotating support rod 12. 11, and a rotating cylinder 21 is rotatably installed on the inner wall of the fixed cylinder 11. A mounting box 9 is installed on the top of the rotating cylinder 21. Four abutments 8 are provided above the mounting box 9. A control component for driving the four abutments 8 to move synchronously is provided inside the mounting box 9. Slots 14 are transversely penetrating inside the rotating support rod 12 and the second mounting bracket 15. Two fixing rings 24 are installed at one end of the second mounting bracket 15. Insert rods 23 matching their cross-sections are penetrating inside the slots 14. Second positioning holes 25 are penetrating inside the insert rods 23 and the outer wall of the fixing rings 24.
[0024] The connection between the rotating strut 12 and the empty slot 13 is a rotatable connection, and the rotation range of the rotating strut 12 is 0°-90°;
[0025] Specifically, such as Figure 1 and Figure 3As shown, when machining the end face of the annular workpiece, the rotating support rod 12 can be rotated to a vertical position. At this time, the insertion rod 23 is inserted through the corresponding slot 14 to restrict the rotation of the rotating support rod 12. One end of the insertion rod 23 will be inserted into the corresponding fixing ring 24. At this time, a screw can be used to pass through the second positioning hole 25 on the fixing ring 24 and the insertion rod 23, and the end can be sealed with a bolt to determine the position of the insertion rod 23. After that, the annular workpiece can be placed on the outside of multiple abutment plates 8. Then, the multiple abutment plates 8 are moved outward simultaneously with the help of the control component until they abut against the inner wall of the workpiece, quickly completing the clamping and positioning of the annular workpiece. When it is necessary to machine the outer wall of the annular workpiece, the rotating support rod 12 can be placed in a horizontal position and then fixed by the above method, and clamped by the cooperation of the limiting plate 5 and the mounting box 9.
[0026] The connection between the fixed cylinder 11 and the rotating cylinder 21 is a rotatable connection, and the first positioning hole 22 is passed through both sides of the outer wall of the fixed cylinder 11 and the rotating cylinder 21.
[0027] Specifically, such as Figure 1 and Figure 2 As shown, when processing the outer wall of the annular workpiece, the limiting plate 5 can drive the workpiece and the mounting box 9 to rotate. Therefore, the fixed cylinder 11 and the rotating cylinder 21 are rotatably connected. When processing the end face of the annular workpiece, it is necessary to keep the mounting box 9 stable and restrict its rotation. Therefore, the first positioning hole 22 on the outer wall of the rotating cylinder 21 and the fixed cylinder 11 can be aligned. Then, a screw is used to pass through the first positioning hole 22, and bolts are used to further restrict it, so that the fixed cylinder 11 and the rotating cylinder 21 cannot rotate relative to each other, thus ensuring the stability of the mounting box 9.
[0028] The drive assembly includes an electric push rod 1. The electric push rod 1 is mounted on one side of the first mounting bracket 2, and the output end of the electric push rod 1 extends into the interior of the first mounting bracket 2 and is mounted on a sliding box 4. The sliding box 4 and the first mounting bracket 2 are connected by a sliding connection. The top of the sliding box 4 is mounted on a first servo motor 3, and the output end of the first servo motor 3 extends into the interior of the sliding box 4 and is mounted on a driving helical gear 27. A rotating shaft 6 is mounted on one side of the interior of the sliding box 4 through a rotating shaft, and one end of the rotating shaft 6 extends to the outside of the sliding box 4 and is fixed to one side of the limiting plate 5. A driven helical gear 26 that meshes with the driving helical gear 27 is fixed to the outer wall of the rotating shaft 6 inside the sliding box 4.
[0029] Specifically, such as Figure 1 and Figure 5As shown, starting the electric push rod 1 can control the sliding box 4 to move inside the first mounting frame 2, thereby changing the distance between the limiting plate 5 and the mounting box 9, so that the limiting plate 5 can cooperate with the mounting box 9 to complete the clamping work. After clamping is completed, the first servo motor 3 is started, and the rotating shaft 6 is driven to rotate by the cooperation of the driving helical gear 27 and the driven helical gear 26. The rotation of the rotating shaft 6 can cause the limiting plate 5 to rotate, thereby driving the annular workpiece to rotate, so that different positions of the outer wall of the annular workpiece can approach the mechanical equipment used for processing.
[0030] The control assembly includes a rotating disk 19, which is rotatably mounted on the inner wall of the mounting box 9. The mounting box 9 has four vertically penetrating arc-shaped grooves 16. The inner wall of the mounting box 9 is equipped with four fixed guide rods 18 at equal angles. The outer walls of the fixed guide rods 18 are all slidably mounted with sliding rods 20. The top ends of the four sliding rods 20 are respectively fixed to the bottom ends of the four abutments 8, and the bottom ends of the four sliding rods 20 extend into the interior of the four arc-shaped grooves 16.
[0031] The width of the arc-shaped groove 16 is equal to the diameter of the sliding rod 20, and the arc-shaped groove 16 is centrally symmetrical about the rotation center of the rotating disk 19;
[0032] A mounting ring 28 is fixed to the bottom of the rotating disk 19, and a conical gear ring 17 is fixed to the outer wall of the mounting ring 28. A second servo motor 10 is installed on one side of the mounting box 9, and the output end of the second servo motor 10 extends into the interior of the mounting box 9 and is equipped with a conical gear 29. The conical gear 29 meshes with the conical gear ring 17.
[0033] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, starting the second servo motor 10 can drive the bevel gear 29 to rotate, thereby driving the mounting ring 28 and the rotating disk 19 to rotate through the cooperation of the bevel gear 29 and the bevel gear ring 17. As the rotating disk 19 rotates, the position of the arc groove 16 changes, so the sliding rod 20 is squeezed and pushed by the inner wall of the arc groove 16, and it can move in a direction under the guidance of the fixed guide rod 18, thereby making the four abutments 8 move at the same speed.
[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
