[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 3 This utility model relates to a preferred embodiment of an automatic cone reversing machine.

[0032] The automatic tapered reversing machine includes: a bed 1, a tapered grinding mechanism, an X-axis feed mechanism, and a Z-axis feed mechanism. The bed 1 is equipped with a workpiece to be processed. The tapered grinding mechanism is used to grind the workpiece. The X-axis feed mechanism and the Z-axis feed mechanism are arranged orthogonally to control the feed motion of the grinding wheel 4 in the X and Z axes, respectively.

[0033] In this embodiment, the main structure of the bed 1 is constructed using aluminum profiles, which reduces the overall weight of the equipment and controls the cost.

[0034] Specifically, the first part is the tapered grinding mechanism, which includes a power motor 2, a main drive shaft 3, and a grinding wheel 4. The main drive shaft 3 is directly connected to the output end of the power motor 2, and the grinding wheel 4 is installed at the output end of the main drive shaft 3 for grinding the equipment to be processed.

[0035] Preferably, the grinding wheel 4 is connected to the power motor 2 via the grinding wheel mother disc 5, and the entire grinding wheel 4 is covered by the grinding wheel protective cover 6, which ensures the stability and safety of the grinding wheel 4 when rotating at high speed, and also prevents the flying of chips during the grinding process.

[0036] Secondly, there is the X-axis feeding mechanism, which includes a lifting stepper motor 7, a feed screw 8, an upper moving plate 9, a top plate 10, and a moving column 11.

[0037] The lifting stepper motor 7 is connected to the feed screw 8 for transmission. The upper moving plate 9 is located above the lifting stepper motor 7 and is connected to the top plate 10 through four moving columns 11. The four moving columns 11 adopt a symmetrical distribution structure to form a support frame to avoid vibration or tilting during X-axis movement.

[0038] The power motor 2 is connected to the lifting stepper motor 7 through the upper moving plate 9, the top plate 10 and the moving column 11. When the lifting stepper motor 7 rotates, it transmits motion through the feed screw 8 and the moving column 11, driving the power motor 2 and the grinding wheel 4 to feed in the X direction.

[0039] The operation process of the X-axis feed mechanism is as follows:

[0040] After receiving the control signal, the lifting stepper motor 7 drives the feed screw 8 to rotate. The screw nut drives the upper moving plate 9 to move axially. Through the synchronous guidance of the four moving columns 11, the linear motion is transmitted to the top plate 10, which finally drives the power motor 2 and the grinding wheel 4 to achieve precise X-axis feeding.

[0041] The aforementioned X-axis feed mechanism achieves stable transmission through a combination of lifting stepper motor 7, feed screw 8, and moving column 11.

[0042] Furthermore, the Z-axis feed mechanism includes a moving stepper motor 12, a ball screw connecting plate 13, a screw seat connecting block 14, a moving base plate, and a lower moving plate 16.

[0043] The moving stepper motor 12 is connected to the ball screw drive, the ball screw is connected to the ball screw connecting plate 13, the ball screw connecting plate 13 is connected to the screw seat connecting block 14 by bolts, and the screw seat connecting block 14 is connected to the moving base plate 15 and the lower moving plate 16.

[0044] Furthermore, a central shaft protective sleeve 17 is provided on the main drive shaft 3. The central shaft protective sleeve 17 passes through the moving base plate 15 and the lower moving plate 16 of the Z-axis feed mechanism to realize the feed movement of the grinding wheel 4 in the Z-axis.

[0045] The operation process of the Z-axis feed mechanism is as follows:

[0046] After receiving the control signal, the moving stepper motor 12 drives the ball screw to rotate. The rotational motion is converted into linear displacement through the ball screw connecting plate 13. The screw seat connecting block 14 synchronously drives the moving base plate 15 and the lower moving plate 16 to reciprocate in the Z direction. The radial runout of the main drive shaft 3 is constrained by the central shaft protective sleeve 17. Finally, the grinding wheel 4 achieves precise feed in the Z direction.

[0047] The Z-axis feed mechanism described above converts the rotational motion of the moving stepper motor 12 into the linear reciprocating motion of the grinding wheel 4 through the combination of the ball screw, the ball screw connecting plate 13 and the moving base plate 15. It has a compact structure and meets the requirements of high-precision grinding.

[0048] Based on the above structure, the automatic tapered machine of this utility model also includes a PLC control unit. The PLC control unit is electrically connected to the power motor, the lifting stepper motor, and the moving stepper motor. The PLC control unit controls the start, stop, and speed of the power motor 2, the lifting stepper motor 7, and the moving stepper motor 12 to achieve three-axis linkage. At the same time, the PLC control unit can more accurately position the tapered position and distance, improving the grinding accuracy.

[0049] Through the above-mentioned PLC intelligent control, the precise positioning of the inverted cone position and distance can be achieved, significantly improving the processing accuracy. The automated program control simplifies the operation process, reduces the requirements for operators, and reduces labor costs.

[0050] The beneficial effects of this automatic cone reversing machine are:

[0051] Lightweight design: High-strength aluminum profiles are used to replace the traditional steel structure as the main body of the bed, which greatly reduces the overall weight of the equipment and makes it easier to transport and install;

[0052] Precision transmission control: The X and Z feeds are driven by stepper motors and precision lead screws, combined with PLC intelligent control, to achieve high-precision feed. It can achieve precise positioning of the inverted cone position and distance, and is suitable for precision machining scenarios such as inverting and grinding, ensuring the quality of the machined surface and dimensional accuracy.

[0053] Improved efficiency and cost control: Automated control simplifies the operation process, improves the efficiency of the cone reversing mechanism, reduces the requirements for operators, and reduces labor costs.

[0054] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
