Description

Technical Field

[0001] This invention belongs to the field of surface treatment technology and relates to a five-axis curved surface grinding, polishing and wire drawing integrated processing equipment. Background Technology

[0002] Grinding, polishing, and wire drawing are common techniques for surface treatment of metals and non-metals. To achieve metal wire drawing, the process is usually carried out manually using a wire drawing machine. Before wire drawing, the surface needs to be ground, then polished, and finally wire drawing. Currently, surface treatment processes on the market mainly have the following two problems:

[0003] 1. In recent years, my country's manufacturing industry has developed rapidly. Many workpieces have complex curved surfaces and require surface grinding and polishing. Grinding can transform unevenness, inconsistent thickness, or other defects in the workpiece surface into a smooth surface with uniform thickness that meets various process requirements and standards. However, for workpieces with irregular structures and complex curvatures, grinding and polishing are often done manually, resulting in low overall work efficiency and poor product quality stability.

[0004] 2. In surface treatment processing, based on different processing characteristics, it is mainly divided into three processing stages: grinding, polishing and wire drawing. After the previous processing stage is completed, it needs to be transferred before the next process can be carried out. This results in longer processing time, increased labor intensity for workers, and lower production efficiency. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A five-axis integrated processing equipment for grinding, polishing and wire drawing of curved surfaces includes: a four-axis machine base and an integrated processing head;

[0007] The four-axis machine tool is equipped with an X-axis, a Y-axis, a Z-axis, and a C-axis that rotates around the Z-axis;

[0008] Wherein: the Y-axis is a set of Y-moving modules, and the movable part of the Y-moving module is equipped with a processing table for placing the product to be processed;

[0009] The X-axis is a set of X-axis moving modules that span the upper part of the machining table;

[0010] The Z-axis is a set of Z-axis lifting modules mounted on the movable part of the X-axis moving module;

[0011] The C-axis is a set of C-axis rotary motors mounted on the lifting part of the Z-axis lifting module;

[0012] The integrated machining head includes: a mechanism base, on which a mounting bearing is provided to be installed and fitted with the drive shaft of the C-axis rotary motor, and the integrated machining head is driven to rotate along the C-axis by the C-axis rotary motor;

[0013] The mechanism base is equipped with a B-axis that rotates around the Y-axis. The B-axis is a set of B-axis rotary motors mounted on the mechanism base. The rotary base is mounted on the drive shaft of the B-axis rotary motors, and the rotary base is driven to rotate the B-axis by the B-axis rotary motors.

[0014] A wire drawing wheel shaft is installed at one end of the upper and lower ends of the rotating base, and a wire drawing wheel is installed on the wire drawing wheel shaft; a downwardly extending mounting shaft is installed at the other end of the rotating base, and a grinding wheel or a wire drawing wheel can be installed on the mounting shaft.

[0015] A synchronous drive module is also installed on the rotating base, which drives the wire drawing wheel shaft and the mounting shaft to rotate synchronously.

[0016] As a further aspect of the present invention: the synchronous drive module includes: a drive motor for realizing drive operation, wherein the output axis of the drive motor extends downward and is in drive cooperation with the mounting shaft;

[0017] A transmission synchronous shaft is arranged parallel to the wire drawing wheel shaft. Both the transmission synchronous shaft and the wire drawing wheel shaft are fitted with transmission wheels, and a transmission belt is provided between the two sets of transmission wheels. Synchronous transmission between the transmission synchronous shaft and the wire drawing wheel shaft is achieved through the transmission belt.

[0018] A horizontal transmission gear is nested on the output shaft of the drive motor, and a vertical transmission gear is nested on the synchronous transmission shaft; the horizontal transmission gear and the vertical transmission gear achieve intersecting shaft gear transmission cooperation.

[0019] The beneficial effects of this invention are:

[0020] 1. The system is equipped with a Y-axis moving module, an X-axis moving module, a Z-axis lifting module, a C-axis rotary motor, and a B-axis rotary motor. These components work together to drive the product and the grinding wheel (polishing wheel) or wire drawing wheel to perform five-axis relative positioning, thereby achieving grinding, polishing, and wire drawing of curved and irregularly shaped product surfaces. The entire surface treatment process is highly automated, greatly improving work efficiency.

[0021] 2. It combines grinding, polishing and wire drawing working structures, and in conjunction with surface treatment equipment, it can realize automated grinding, polishing and wire drawing surface treatment of metal and non-metal workpieces. The entire processing process can be completed in the same processing equipment without intermediate transfer work, realizing uninterrupted processing. This not only effectively improves processing efficiency and reduces labor intensity, but also ensures that the total feed rate of surface treatment is accurately controlled, thereby improving processing quality.

[0030] This invention provides reference to [the relevant document]. Figures 1-4 In this embodiment of the invention, a five-axis curved surface grinding, polishing and wire drawing integrated processing equipment includes: a four-axis machine base 2 and an integrated processing head 1;

[0031] The four-axis machine tool 2 is equipped with an X-axis, a Y-axis, a Z-axis, and a C-axis that rotates around the Z-axis;

[0032] Wherein: the Y-axis is a set of Y-moving modules 21, and a processing table 22 for placing the product to be processed is installed on the movable part of the Y-moving module 21;

[0033] The X-axis is a set of X-axis moving modules 23 that span the upper end of the machining table 22;

[0034] The Z-axis is a set of Z-axis lifting modules 24 mounted on the movable part of the X-axis moving module 23;

[0035] The C-axis is a set of C-axis rotary motors (not shown) mounted on the lifting part of the Z-axis lifting module 24;

[0036] The integrated machining head 1 includes: a mechanism base 12, on which a mounting shaft 16 bearing 10 is provided to be installed and cooperated with the drive shaft of the C-axis rotary motor, and the integrated machining head 1 is driven to rotate in the C-axis by the C-axis rotary motor;

[0037] The mechanism base 12 is provided with a B-axis that rotates around the Y-axis. The B-axis is a set of B-axis rotary motors 11 mounted on the mechanism base 12. A rotating base 15 is mounted on the drive shaft of the B-axis rotary motor 11. The B-axis rotary motor 11 drives the rotating base 15 to rotate the B-axis.

[0038] A wire drawing wheel shaft 14 is installed at one end of the upper and lower ends of the rotating base 15, and a wire drawing wheel 13 is installed on the wire drawing wheel shaft 14; a downwardly extending mounting shaft 16 is installed at the other end of the rotating base 15, and a grinding wheel (polishing wheel) or a wire drawing wheel 13 can be installed on the mounting shaft 16.

[0039] A synchronous drive module 17 is also installed on the rotating base 15, which drives the wire drawing wheel shaft 14 and the mounting shaft 16 to rotate synchronously.

[0040] In practical implementation, the synchronous drive module 17 achieves the effect of providing power to two processing groups from a single drive source. The B-axis rotary motor 11 drives the grinding wheel (polishing wheel) or wire drawing wheel 13 involved in the process to rotate toward the product to be processed. The Y-axis moving module 21, X-axis moving module 23, Z-axis lifting module 24, C-axis rotary motor and B-axis rotary motor 11 work together to drive the product and the grinding wheel (polishing wheel) or wire drawing wheel 13 to cooperate in five-axis relative positions, so as to realize the grinding, polishing and wire drawing work on the surface of the curved and irregular product.

[0041] Furthermore, the synchronous drive module 17 includes a drive motor 171 for driving operations, the output shaft of the drive motor 171 extending downward and engaging with the mounting shaft 16 in a transmission manner.

[0042] A transmission synchronous shaft 175 is arranged parallel to the wire drawing wheel shaft 14. Both the transmission synchronous shaft 175 and the wire drawing wheel shaft 14 are fitted with transmission wheels 174, and a transmission belt 176 is provided between the two sets of transmission wheels 174. The synchronous transmission between the transmission synchronous shaft 175 and the wire drawing wheel shaft 14 is realized through the transmission belt 176.

[0043] A horizontal transmission gear 172 is nested on the output shaft of the drive motor 171, and a vertical transmission gear 173 is nested on the transmission synchronous shaft 175; the horizontal transmission gear 172 and the vertical transmission gear 173 achieve intersecting shaft gear transmission cooperation.

[0044] During operation, the drive motor 171 drives the wire drawing wheel shaft 14 to rotate, thereby driving the grinding wheel (polishing wheel) to work. The output shaft of the drive motor 171 drives the horizontal transmission gear 172 to drive the vertical transmission gear 173 to move, and then drives the transmission synchronous shaft 175 to work through the vertical transmission gear 173. Finally, the transmission synchronous shaft 175 drives the wire drawing wheel shaft 14 to rotate, thereby achieving the effect of synchronous work between the wire drawing wheel 13 and the grinding wheel (polishing wheel).

[0045] Furthermore, several sets of anti-collision sensors 19 are installed on the rotating base 15. The multiple anti-collision sensors 19 are divided into two groups and are both installed on the buffer base plate 181. One group of anti-collision sensors 19 senses and monitors the wire drawing wheel 13 side, and the other group of anti-collision sensors 19 senses and monitors the grinding wheel (polishing wheel) side. During the wire drawing, grinding and polishing process, the anti-collision sensors 19 determine the distance between the wire drawing wheel 13 and the grinding wheel (polishing wheel) and the processing surface. By sensing, the wire drawing wheel 13 and the grinding wheel (polishing wheel) are prevented from colliding with the workpiece, thereby improving the safety and accuracy of the processing.

[0046] Furthermore, a set of anti-collision buffer mechanism 8 is also installed on the rotating base 15. When the wire drawing wheel 13 and the grinding wheel (polishing wheel) collide with the workpiece, the anti-collision buffer mechanism 8 can achieve anti-collision buffering to avoid damage to the wire drawing wheel 13, the grinding wheel (polishing wheel), and the workpiece.

[0047] The anti-collision buffer mechanism 8 includes: a buffer base plate 181 and a pair of buffer slide rails 185 fixedly installed on the rotating base 15. The buffer base plate 181 is installed on the buffer slide rails 185 through a slider 184. The output shaft of the B-axis rotary motor 11 is connected to the buffer base plate 181. During buffering, the buffer base plate 181 is fixed.

[0048] Both ends of the buffer slide rail 185 are provided with fixed base plates 182, which are fixedly installed on the rotating base 15; both ends of the buffer base plate 181 are provided with a number of spring support rods 183, and the other end of the spring support rods 183 extends outward through the fixed base plate 182; each spring support rod 183 is nested with a buffer spring, which abuts against the buffer base plate 181 and the fixed base plate 182 respectively.

[0049] When a collision occurs, the lower buffer spring is compressed, causing the rotating base 15 to slide upward as a whole (through the cooperation of the buffer slide rail 185 and the slider 184), thus achieving the effect of collision buffering.

[0050] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
