Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, and in particular to a CNC machine tool composite machine for processing metal faucets and its processing method. Background Technology

[0002] The CNC composite machine tool for metal faucet processing is a high-precision CNC device that integrates multiple machining processes such as drilling, milling, tapping, turning, and boring. In the bathroom industry, traditional metal faucet shell processing often requires repeated clamping on multiple machines such as lathes and drilling machines, which is not only cumbersome but also prone to introducing positioning errors. This type of composite machine, by integrating multiple processes onto a single machine, can complete the complex machining of faucets and various valve bodies in a single clamping operation. This solves the problem of low processing efficiency caused by multiple clamping operations in traditional processes and significantly improves the positional accuracy and yield rate of faucet body machining.

[0003] These types of equipment typically employ a rotary or multi-spindle layout in their structural design, enabling high-speed cutting and rigid drilling capabilities. For example, some models can be equipped with eight or more workstations, integrating up to dozens of power heads to achieve parallel operations such as drilling, tapping, milling, and even tool-setting machining.

[0004] Although existing equipment has greatly shortened the processing time, the clamping time is still difficult to reduce. During loading, in order to avoid interference with the various processing tools and to provide space for clamping the workpiece, it is necessary to move the processing positions out of the way to avoid interference, which increases the processing time. Summary of the Invention

[0005] This invention provides a CNC machine tool composite machine for processing metal faucets and its processing method, which increases turnover efficiency and ensures safe and reliable clamping.

[0006] This invention provides a CNC machine tool composite machine for processing metal faucets, comprising a processing system, a multi-workpiece rotary system, two friction springs, and a material guiding system. The material guiding system is mounted on the multi-workpiece rotary system. The processing system includes a processing frame, an upper processing device, and two oppositely arranged side processing devices. The upper processing device is slidably mounted on the processing frame in a vertical direction and has a rotating output end. The two friction springs are mounted at the bottom of the output end of the upper processing device. The upper processing device includes a lifting device and an upper drilling device. The lifting device is slidably mounted on the processing frame in a vertical direction, and the upper drilling device is mounted on the lifting device. The two friction springs... The friction springs are installed at the output end of the upper drilling device. The distance between the two friction springs in the free state is greater than the inner diameter of the head workpiece. An electromagnet is provided between two adjacent friction springs through a rotary joint. When the two electromagnets are energized, the two friction springs are disengaged from the head workpiece. When the two electromagnets are de-energized, the two friction springs are spread apart. The two side processing devices are slidably installed on the processing frame in the horizontal direction. The sliding directions of the two side processing devices are opposite. The multi-workpiece rotation system has several clamping positions. Each clamping position is released when it is disengaged from the lower side of the upper processing device. When the material guiding system is located on the lower side of the upper processing device, the output end of the upper processing device rotates.

[0007] Preferably, the multi-workpiece rotation system includes a rotation device and several rotation clamping devices. Each rotation device is installed on the lower side of the processing frame, and each rotation clamping device is installed on the rotation device. The rotation trajectory of each rotation clamping device is located on the lower side of the upper processing device, and each rotation clamping device constitutes a clamping position.

[0008] Preferably, the rotary device includes an indexer and a rotary support plate, the rotary support plate being mounted on the upper side of the indexer, and each of the rotary clamping devices being mounted on the rotary support plate.

[0009] Preferably, the rotary gripping device includes a rotary gripping air finger and a gripping template, wherein the gripping template is installed at the output end of the rotary gripping air finger.

[0010] Preferably, the material guiding system includes a plurality of inclined plates, each of which is located between adjacent rotary gripping devices.

[0011] Preferably, the side machining device includes a transverse movement device and a side drilling device, wherein the transverse movement device is slidably mounted on the machining frame in the horizontal direction, and the side drilling device is mounted on the transverse movement device.

[0012] The machining method of a CNC machine tool composite machine for processing metal faucets includes the following steps: S1: Each clamping position clamps the faucet workpiece; S2: When the upper processing device cuts the faucet workpiece downwards, the two friction springs move downwards along the preset hole position of the faucet workpiece. S3: Each clamping position is released when it is disengaged from the lower side of the upper processing device, and the multi-workpiece rotation system rotates. S4: When the material guiding system is located below the upper processing device, the output end of the upper processing device rotates, and the head workpiece rotates with the two friction springs under its own inertia. The head workpiece falls to the material guiding system under its own gravity.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The material guiding system is installed on the multi-workpiece rotary system to guide the faucet workpiece to the workpiece carrier frame at a fixed position when the faucet workpiece falls. Although there are multiple material guiding systems, the material guiding system is only used to guide the material when it is on the upper side of the workpiece carrier frame. The processing system includes a processing frame, an upper processing device and two oppositely arranged side processing devices. The upper processing device is slidably installed on the processing frame in the vertical direction and has a rotating output end. The upper processing device and the two oppositely arranged side processing devices enable the faucet to be processed simultaneously in three positions.

[0014] Two friction springs are installed at the bottom of the output end of the upper processing device. The distance between the two friction springs in their free state is greater than the inner diameter of the faucet workpiece. An electromagnet is provided between two adjacent friction springs via a rotary joint. When the output end of the upper processing device rotates, the two electromagnets are energized, causing the two friction springs to detach from the faucet workpiece. When processing stops at the output end of the upper processing device, the two electromagnets are de-energized, causing the two friction springs to spread apart and support the faucet workpiece inside. When the multi-workpiece rotation system releases the faucet workpiece and rotates, the faucet workpiece is temporarily hung on the upper processing device by the friction of the two friction springs. On the processing device, as the multi-workpiece rotary system continues to rotate and deliver the next faucet workpiece, the upper processing device rotates, and the faucet workpiece slides against the two friction springs due to its own inertia. The faucet workpiece falls under its own gravity. When the upper processing device cuts downward to process the faucet workpiece, the two friction springs move downward along the preset holes of the faucet workpiece and support the faucet workpiece inside. The two side processing devices are slidably mounted on the processing frame in the horizontal direction. The sliding directions of the two side processing devices are opposite, so as to realize simultaneous processing in both directions. The upper processing device and the two oppositely arranged side processing devices simultaneously form three holes on the faucet workpiece.

[0015] The multi-workpiece rotary system has several clamping positions, each clamping a dragon head workpiece. After processing, when the multi-workpiece rotary system is about to rotate so that the corresponding clamping position is disengaged from the lower side of the upper processing device, each clamping position is released, allowing the dragon head workpiece to detach from the clamping position. Subsequently, the multi-workpiece rotary system rotates, while the dragon head workpiece is temporarily suspended under the upper processing device. When the guide system rotates to a position below the upper processing device, the output end of the upper processing device rotates, and the dragon head workpiece rotates relative to the two friction springs due to its own inertia. The dragon head workpiece falls to the guide system under its own gravity. Due to the conveying effect of the multi-workpiece rotary system, when manually clamping and loading, the dragon head workpiece clamping position is far away from the processing system. The processing system does not need to retreat the upper processing device and the two oppositely positioned side processing devices too far to avoid the worker, greatly reducing the idle stroke of the processing system and increasing the turnover efficiency. The combined use of the two friction springs and the multi-workpiece rotary system avoids the dragon head workpiece from colliding with the multi-workpiece rotary system, allowing the multi-workpiece rotary system to rotate quickly.

Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] The following is combined with Figures 1-5As shown, this embodiment provides a CNC machine tool composite machine for processing metal faucets, including a processing system 1, a multi-workpiece rotary system 2, two friction springs 31, and a material guiding system 4. The material guiding system 4 is installed on the multi-workpiece rotary system 2 to guide the faucet workpiece 5 to the workpiece support frame 6 at a fixed position when it falls. Note that although there are multiple material guiding systems 4, they are only used to guide the material when it is on the upper side of the workpiece support frame 6. The processing system 1 includes a processing frame 11, an upper processing device 12, and two oppositely arranged side processing devices 13. The upper processing device 12 is slidably installed on the processing frame 11 in the vertical direction and has a rotating output end. The upper processing device 12 and the two oppositely arranged side processing devices 13 realize the simultaneous processing of the faucet in three positions.

[0028] Two friction springs 31 are installed at the bottom of the output end of the upper processing device 12. When the two friction springs 31 are in a free state, the distance between them is greater than the inner diameter of the faucet workpiece (5). When the upper processing device 12 cuts the faucet workpiece 5 downward, the two friction springs 31 move downward along the preset hole position of the faucet workpiece 5 and support the faucet workpiece 5 inside the faucet workpiece 5. The two side processing devices 13 are slidably installed on the processing frame 11 in the horizontal direction. The sliding directions of the two side processing devices 13 are opposite, so as to realize simultaneous processing in both directions. The upper processing device 12 and the two oppositely arranged side processing devices 13 simultaneously form three holes on the faucet workpiece 5, so as to realize simultaneous forming.

[0029] The multi-workpiece rotary system 2 has several clamping positions, each clamping a dragon head workpiece 5. After processing, when the multi-workpiece rotary system 2 is about to rotate so that the corresponding clamping position is disengaged from the lower side of the upper processing device 12, each clamping position is released, allowing the dragon head workpiece 5 to disengage from the clamping position. Subsequently, the multi-workpiece rotary system 2 rotates, while the dragon head workpiece 5 is temporarily suspended below the upper processing device 12. When the guide system 4 rotates to a position below the upper processing device 12, the output end of the upper processing device 12 rotates, and the dragon head workpiece 5 rotates relative to the two friction springs 31 due to its own inertia. Under its own gravity, the workpiece falls to the material guiding system 4. Due to the conveying effect of the multi-workpiece rotary system 2, when the workpiece is manually clamped and loaded, the clamping position of the head workpiece 5 is far away from the processing system 1. The processing system 1 does not need to retreat too far to avoid the workers, so the idle stroke of the processing system 1 is greatly reduced, increasing the turnover efficiency. The cooperation between the two friction springs 31 and the multi-workpiece rotary system 2 avoids the head workpiece 5 from hitting the multi-workpiece rotary system 2, so that the multi-workpiece rotary system 2 can rotate quickly and the clamping is safe and reliable.

[0030] To reduce the wear of the two friction springs 31, an electromagnet is provided between the two adjacent friction springs 31 through a rotary joint. When the output end of the upper processing device 12 rotates, the two electromagnets are energized, causing the two friction springs 31 to detach from the head workpiece 5, thus avoiding unnecessary wear during processing. When the output end of the upper processing device 12 stops processing, the two electromagnets are de-energized, causing the two friction springs 31 to open up and support the head workpiece (5) inside the head workpiece 5. When the multi-workpiece rotary system 2 releases the head workpiece 5 and rotates, the head workpiece 5 is temporarily hung on the upper processing device 12 by the friction of the two friction springs 31. As the multi-workpiece rotary system 2 continues to rotate and delivers the next head workpiece 5, the upper processing device 12 rotates, and the head workpiece 5 slides against the two friction springs 31 under its own inertia. The head workpiece 5 falls under its own gravity.

[0031] Specifically, the multi-workpiece rotary system 2 includes a rotary device 21 and several rotary clamping devices 22. Each rotary device 21 is installed on the lower side of the processing frame 11, and each rotary clamping device 22 is installed on the rotary device 21. The rotary trajectory of each rotary clamping device 22 is located on the lower side of the upper processing device 12. Each rotary clamping device 22 constitutes a clamping position, thereby realizing the clamping of the dragon head workpiece 5.

[0032] Specifically, the rotary device 21 includes an indexer 211 and a rotary support plate 212. The rotary support plate 212 is installed on the upper side of the indexer 211, and each rotary gripping device 22 is installed on the rotary support plate 212. The indexer 211 realizes the periodic rotation of each rotary gripping device 22. The indexer 211 is driven by a motor, which is existing technology purchased commercially and will not be described in detail here.

[0033] Specifically, the rotary clamping device 22 includes a rotary clamping air finger 221 and a clamping template 222. The clamping template 222 is installed at the output end of the rotary clamping air finger 221 to achieve stable clamping of the faucet workpiece 5. The template 222 fits the faucet workpiece 5. The rotary clamping air finger 221 is supplied with air through a rotary joint.

[0034] Specifically, the material guiding system 4 includes several inclined plates, each of which is located between adjacent rotary clamping devices 22. When the inclined plates rotate to the upper processing device 12, they guide the head workpiece 5.

[0035] Specifically, the upper processing device 12 includes a lifting device 121 and an upper drilling device 122. The lifting device 121 is slidably mounted on the processing frame 11 in the vertical direction. The lifting device 121 is a commercially available motor screw lifting mechanism. The output end of the upper drilling device 122 constitutes the output end of the upper processing device 12. The upper drilling device 122 is mounted on the lifting device 121. Two friction springs 31 are mounted on the output end of the upper drilling device 122. The bottom of the two friction springs 31 is provided with a clearance bevel. After the processing is completed, the two friction springs 31 temporarily clamp the faucet workpiece 5, so that the faucet workpiece 5 is suspended on the friction springs 31 until the upper drilling device 122 rotates again and the faucet workpiece 5 falls under its own weight.

[0036] The two friction springs 31 are integrally formed from spring steel sheets. From top to bottom, the two friction springs 31 are an elastic section, a clamping section, and a clearance section. The elastic section is installed at the bottom of the output end of the upper drilling device 122 by welding or screw fixing. When the clamping section is open, it fits against the inner side wall of the faucet workpiece 5. The two clearance sections are deflected in a way that they are close to each other to achieve clearance. When the two elastic sections are in a free state, the distance between them is greater than the inner diameter of the faucet workpiece 5, thereby ensuring that the faucet workpiece 5 is elastically clamped.

[0037] Specifically, the side processing device 13 includes a transverse movement device 131 and a side drilling device 132. The transverse movement device 131 is slidably mounted on the processing frame 11 in the horizontal direction. The transverse movement device 131 is a commercially available motor screw transverse movement mechanism. The side drilling device 132 is mounted on the transverse movement device 131 to realize the side drilling processing of the faucet workpiece 5.

[0038] After processing, the two friction springs 31 temporarily clamp the faucet workpiece 5, allowing the rotary clamping device 22 to immediately rotate and transport the next faucet workpiece 5, without having to wait for the upper drilling device 122 to be pulled out from the top of the faucet workpiece 5 and for the side drilling device 132 to retract before rotating. After the faucet workpiece 5 is released from the rotary clamping device 22, the upper processing device 12 rotates, causing the faucet workpiece 5 to fall. At this time, the upper processing device 12 rises and the side drilling device 132 retracts to avoid the next faucet workpiece 5, making the entire rotation process smooth and avoiding wasted time. The clamping of the workpiece is carried out during the faucet processing time, resulting in high production efficiency.

[0039] The machining method of a CNC machine tool composite machine for processing metal faucets includes the following steps: S1: Each clamping position clamps the 5-head faucet workpiece; S2: When the upper processing device 12 cuts downwards to process the faucet workpiece 5, the two friction springs 31 move downwards along the preset hole position of the faucet workpiece 5. S3: The multi-workpiece rotary system 2 rotates, and each clamping position is released when it is disengaged from the lower side of the upper processing device 12; S4: When the material guiding system 4 is located below the upper processing device 12, the output end of the upper processing device 12 rotates, and the head workpiece 5 rotates relative to the two friction springs 31 under its own inertia. The head workpiece 5 falls to the material guiding system 4 under its own gravity.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
