DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0033] During the manufacturing of spring tubes, it is necessary to peel off the sheath at the end of the spring tube to a certain length to expose the spiral steel wire inside. Figure 1 As shown, it includes a control box 5 and a cutting box 6. The control component in the control box 5 controls the cutting knife in the cutting box 6 to cut the covering skin. When in use, the operator holds the spring tube and sends it into the box from the entrance of the cutting box 6, and visually judges the cutting length of the covering skin through the transparent cutting box 6. This method relies on the subjective judgment of the operator, and the cutting length of the covering skin cannot be kept consistent. The accuracy is low and cannot meet subsequent production needs. This device realizes the automated process of spring tube covering skin circumcision, greatly improving production efficiency. The material sensor can accurately sense the spring tube placed in the first station to ensure the accuracy of subsequent operations. The shearing mechanism can accurately cut the spring tube through the cooperation of the pressing block assembly and the scissors assembly to ensure that the spring tubes entering the third station are of equal length, thereby ensuring the consistency of the cutting length of the covering skin and reducing the errors that may be caused by human operation.

[0034] The specific structure of the spring tube sheathing ring cutting device provided by the present application is described in detail below in conjunction with the accompanying drawings.

[0035] Reference Figure 2 As shown, a spring tube sheathing ring cutting device provided in an embodiment of the present application comprises a machining center 1 and a workbench 2, wherein the workbench 2 is placed at the inlet end of the machining center 1. Figure 3 and Figure 4 As shown, the machining center 1 includes a first workstation 11, a second workstation 12, a third workstation 13 and a fourth workstation 14 arranged in parallel in sequence, and also includes a controller 17; the first workstation 11, the second workstation 12 and the third workstation 13 are provided with a common bottom transfer clamp 15; a transfer robot 16 is provided between the third workstation 13 and the fourth workstation 14.

[0036] It should be noted that the distance between the first station 11 and the second station 12 is equal to the distance between the second station 12 and the third station 13 to ensure that the bottom transfer clamp 15 is shared by the first station 11, the second station 12 and the third station 13.

[0037] The first station 11 is provided with a material sensor 113 for sensing the spring tube placed in the first station 11. When the material sensor 113 senses the spring tube, the controller 17 issues a control command at a preset time interval, and the bottom transfer clamp 15 is activated to transport the spring tube to the second station 12. Through the real-time sensing of the material sensor 113 and the precise control of the controller 17, the spring tube can be quickly transported from the first station 11 to the second station 12, reducing the time of manual transportation and improving the overall production efficiency.

[0038] The second station 12 is provided with a shearing mechanism 121, which is arranged on a side of the machining center 1 away from the workbench 2 to ensure that the spring tubes entering the third station 13 are of equal length. The automated shearing process reduces the time and possible errors of manual operation, and the spring tubes entering the third station 13 are of equal length, avoiding subsequent processing problems caused by different lengths of spring tubes, and improving the overall quality and consistency of the product.

[0039] The third station 13 is provided with a standard ring cutting machine to ring cut the sheath at the end of the spring tube entering the third station 13. The standard ring cutting machine has a high-precision servo system and realizes automatic cutting through a PLC control system and a touch screen. It can accurately ring cut the sheath at the end of the spring tube according to preset parameters. After ring cutting, the sheath still stays at the end of the spring tube and then enters the fourth station 14, where the sheath separation mechanism 141 separates the cut sheath from the spring tube.

[0040] The controller 17 is configured to generate control instructions for controlling the bottom transfer clamp 15 , the transfer robot 16 , the material sensor 113 , the shearing mechanism 121 , the standard circular cutting machine and the covering skin separation mechanism 141 .

[0041] Reference Figure 4 As shown, in some embodiments, the bottom transfer clamp seat 15 includes a first transfer clamp 151, a second transfer clamp 152, a third transfer clamp 153 and a fourth transfer clamp 154; the machining center 1 includes a machining center material table, wherein the first transfer clamp 151 and the second transfer clamp 152 are located on the side of the machining center material table close to the workbench 2, the third transfer clamp 153 and the fourth transfer clamp 154 ​​are located on the side of the machining center material table away from the workbench 2, the first transfer clamp 151 and the third transfer clamp 153 are symmetrically arranged with the machining center material table as the axis, and the second transfer clamp 152 and the fourth transfer clamp 154 ​​are symmetrically arranged with the machining center material table as the axis. The symmetrical layout ensures stability and balance during movement and reduces transportation problems caused by offset or tilt.

[0042] In the initial state, the first transport clamp 151 and the third transport clamp 153 correspond to the position of the first station 11, and at this time, the second transport clamp 152 and the fourth transport clamp 154 ​​correspond to the position of the second station 12. The spring tube is placed in the first station 11 and clamped by the first transport clamp 151 and the third transport clamp 153. After a preset time interval, the first transport clamp 151 and the third transport clamp 153 move to the second station 12, and at this time, the second transport clamp 152 and the fourth transport clamp 154 ​​move to the third station 13. Subsequently, it returns to the initial state and works in a cycle. It can also be understood that the first transport clamp 151 and the third transport clamp 153 reciprocate between the first station 11 and the second station 12, and the second transport clamp 152 and the fourth transport clamp 154 ​​reciprocate between the second station 12 and the third station 13. This working method realizes a streamlined processing flow, ensuring that the spring tube can be processed continuously and stably at different stations, thereby improving processing efficiency.

[0043] Among them, the first transport clip 151, the second transport clip 152, the third transport clip 153 and the fourth transport clip 154 ​​can be split structures and keep synchronous movement. The first transport clip 151, the second transport clip 152, the third transport clip 153 and the fourth transport clip 154 ​​can also be processed into a whole by setting a connecting structure to control the overall movement. The split structure or the overall structure, both of which provide sufficient flexibility, the split structure is easy to repair and replace, and the overall structure provides higher structural stability and precision.

[0044] Reference Figure 4 and Figure 5 As shown, in some embodiments, the shearing mechanism 121 includes a pressing block assembly and a scissors assembly; the pressing block assembly is located above the second workstation 12, the pressing block assembly includes a pressing block 1211 and a first cylinder 1213, the machining center 1 is provided with a first mounting plate 19, the first cylinder 1213 is connected to the first mounting plate 19, the output end of the first cylinder 1213 drives the pressing block 1211 to reciprocate vertically to fix the spring tube entering the second workstation 12; the scissors assembly includes scissors 1212, and the scissors 1212 cooperate with the pressing block 1211 to cut the spring tube fixed by the pressing block 1211.

[0045] The pressing block 1211 can stably fix the spring tube, while the scissors 1212 can accurately perform the shearing action, avoiding deviation or damage during the shearing process, and improving production efficiency and product quality. The entire shearing process is automatically controlled, and the vertical reciprocating motion of the pressing block 1211 is driven by the first cylinder 1213, without the need for human intervention, which reduces labor intensity and reduces errors caused by human operation. The automated shearing mechanism reduces downtime and waiting time during the production process, making the production line more continuous and efficient. At the same time, due to the stability and accuracy of the shearing operation, the product defect rate and rework rate are reduced, further improving production efficiency and product stability.

[0046] In some embodiments, the first workstation 11 includes an arc clamp 111 and a second cylinder 112; the arc clamp 111 includes a first clamp body 1111 and a second clamp body 1112, the push rod of the second cylinder 112 is fixedly connected to the first clamp body 1111, the second clamp body 1112 is fixedly connected to the material table of the machining center, the first clamp body 1111 reciprocates with the push rod of the second cylinder 112, and the distance between the first clamp body 1111 and the second clamp body 1112 is adapted to the diameter of the spring tube.

[0047] The arc clamp 111 keeps the spring tube placed in the first station 11 straight, and the distance between the first clamp body 1111 and the second clamp body 1112 matches the diameter of the spring tube, ensuring that the spring tube can be accurately clamped. This precise clamping can prevent the spring tube from moving or offsetting during subsequent processing or transfer, thereby improving processing accuracy and product quality. The first clamp body 1111 is driven to reciprocate by the second cylinder 112, thereby realizing automatic clamping and release of the spring tube, reducing the need for manual intervention, reducing labor intensity, and improving production efficiency.

[0048] In some embodiments, it also includes a third cylinder 18, a transfer clamp controller 155 and a transfer clamp control assembly. The machining center includes a second mounting plate 156. The third cylinder 18 is connected to the second mounting plate 156. The third cylinder 18 push rod is connected to the transfer clamp control assembly to control the transfer control clamp control assembly to reciprocate perpendicular to the second mounting plate 156. The transfer clamp controller 155 is connected to the transfer clamp control assembly to control the vertical reciprocating motion of the control assembly push rod. The control assembly push rod is respectively connected to the first transfer clamp 151, the second transfer clamp 152, the third transfer clamp 153 and the fourth transfer clamp 154.

[0049] The connection between the transfer clamp controller 155 and the transfer clamp control assembly realizes the automatic control of the transfer clamp. Through a preset program or instruction, the transfer clamp controller 155 can accurately control the vertical reciprocating motion of the transfer clamp without manual intervention, thereby reducing labor intensity and improving production efficiency. The transfer clamp control assembly enables the system to operate multiple transfer clamps at the same time, realizing parallel processing of multiple workpieces. In addition, by adjusting the number and position of the transfer clamps, the system can adapt to machining centers of different sizes and layouts, and has strong flexibility and expansibility.

[0050] In some embodiments, the third station 13 includes a fixing clamp 131, which is fixedly connected to the material table of the machining center. The fixing clamp 131 fixes the spring tube, ensures the stability of the position of the spring tube during the machining process, prevents the spring tube from moving during the machining process, and thus ensures the machining accuracy.

[0051] In some embodiments, a covering skin collection box is provided below the covering skin separation mechanism 141, and the processing center 1 includes a mounting frame inside, and the covering skin collection box is connected to the mounting frame. The covering skin collection box is mainly used to collect the covering skin separated during the processing process, ensuring the cleanliness of the production site and facilitating subsequent processing or reuse. It is ensured that the separated covering skin can fall directly into the collection box to reduce scattering and secondary operations.

[0052] As the internal structure of the machining center 1, the mounting frame not only provides support and fixation, but also provides mounting locations for various functional components. The mounting frame may be made of metal or other solid materials to ensure its stability and durability. The sheathed collection box may be fixed to the mounting frame by bolts, snaps or other connectors to ensure the stability and reliability of the collection box. The sheathed collection box is firmly fixed inside the machining center to avoid displacement or falling off due to vibration or other factors during the machining process.

[0053] In some embodiments, the workbench 2 includes a first work area 21, a second work area 22 and a third work area 23. The surfaces of the first work area 21 and the third work area 23 are in the same plane, the surface of the second work area 22 is lower than the plane where the first work area 21 and the second work area 22 are located, and the first work area 21 and the third work area 23 are respectively connected to the second work area 22 through transition surfaces, and the transition surfaces are inclined surfaces.

[0054] The inclined surface is used as a transition surface to connect the first working area 21, the second working area 22 and the third working area 23, so that the appearance of the workbench is smoother, and the transition surface helps the workpiece to smoothly transition from the high working area to the low working area.

[0055] In some embodiments, the machining center 1 includes a housing 3, which is provided with an inspection door 31 and a fan 32. The housing 3 is the main structure of the machining center 1, which not only protects the internal precision machinery and electronic components from the influence of the external environment (such as dust, moisture, vibration, etc.), but also provides space for workers to operate and maintain. The inspection door 31 allows workers to easily access the interior of the machining center to perform necessary maintenance, repairs or adjustments. The fan 32 is generally used to cool the electronic components and motors inside the machining center to ensure that they can operate normally even in a high temperature environment. In addition, the fan also helps to remove the heat and harmful gases accumulated inside, and keep the internal environment of the machining center stable.

[0056] In some embodiments, rollers 4 are provided at the bottom of the workbench 2. The provision of the rollers 4 facilitates the movement of the workbench 2 and improves the flexibility and portability of the workbench.

[0057] According to the above technical features, the spring tube sheath circumcision device provided by the present application controls the bottom transfer clamp, transfer manipulator, material sensor, shearing mechanism, standard circumcision machine and sheath separation mechanism through a controller, thereby realizing the automated process of spring tube sheath circumcision and greatly improving the processing efficiency. The shearing mechanism arranged at the second station, combined with the pressing block assembly and the scissors assembly, can accurately cut the spring tube, ensure that the spring tubes entering the third station are of equal length, and provide an accurate positioning basis for subsequent circumcision work.
