A gantry mobile numerical control machine tool

Abstract

This invention provides a gantry-type CNC machine tool for use in the field of CNC machine tools. When transporting workpieces using a rewind box and connecting cable, if the main traction cable breaks, the weight of the workpiece is transferred to the auxiliary traction cable, which temporarily lifts the workpiece, preventing it from falling directly onto the surface of the CNC machine tool base and causing damage. The impact-resistant spherical shell and the filling bladder are optional components. The impact-resistant spherical shell can pause the straightening process of the auxiliary traction cable, dispersing the impact force multiple times, making it less likely for the auxiliary traction cable to break directly under the impact force generated during the workpiece's descent. The rupture of the filling bladder will cause fluorescent pigment to leak out, providing a warning and preventing defective connecting cables and buckles from being used, thus increasing the safety of the CNC machine tool and reducing the risk of destructive accidents.

Description

Technical Field

[0001] This application relates to the field of CNC machine tools, and in particular to a gantry-type moving CNC machine tool. Background Technology

[0002] CNC machine tools automatically process parts according to a pre-programmed machining program. We compile the machining process route, process parameters, tool movement trajectory, displacement, cutting parameters, and auxiliary functions into a machining program sheet according to the instruction codes and program format specified by the CNC machine tool. The contents of this program sheet are then recorded on a control medium and input into the CNC device of the CNC machine tool, thereby directing the machine tool to process the parts.

[0003] The gantry-type mobile CNC machine tool is a product that incorporates gantry crane traction technology into CNC machine tools. The powerful traction capability of the gantry crane can move heavy workpieces to designated machining stations for different processing, and can also move different processing equipment to the workpiece's location for processing, greatly increasing the flexibility of the CNC machine tool, simplifying processing steps, and allowing multiple processing steps for a single part to be performed on the same machine tool. It is suitable for trapezoidal and heavy workpieces.

[0004] When a workpiece is being moved to a different station on a CNC machine tool, if the gantry crane cannot bear the weight of the workpiece and the traction cable breaks, especially if the traction component experiences stress fatigue during operation, even if the weight of the workpiece is within the traction component's bearing capacity after prolonged operation, the traction component may still break. In this case, the workpiece will fall onto the CNC machine tool, and the impact generated by the collision can easily cause irreversible mechanical damage to the CNC machine tool, resulting in huge economic losses. Summary of the Invention

[0005] The purpose of this application is to solve the potential falling accident that may occur when a gantry crane is used to transport a workpiece. Compared with the prior art, it provides a gantry-type mobile CNC machine tool. A pair of matching electric slide rails are carved into a pair of side walls of the CNC machine tool base. A gantry crane is installed above the CNC machine tool base. The gantry crane includes a pair of electric sliders fixedly connected to its upper part, each matching the position of one of the two electric slide rails. The electric sliders are slidably connected within the electric slide rails. A control terminal is fixedly connected to the side wall of the gantry crane. A winding box is carved into its upper part, facing the upper surface of the CNC machine tool base. A pair of connecting cables are fixedly connected inside the winding box. Each connecting cable has a buckle fixedly connected to its end away from the winding box. A workpiece is placed on the upper part of the CNC machine tool base. The end of the connecting cable away from the take-up box passes through the workpiece and is fixedly connected to another connecting cable by a snap fastener. The connecting cable includes a main traction cable and an auxiliary traction cable, and the auxiliary traction cable has a higher structural strength than the main traction cable. The main traction cable and the auxiliary traction cable are covered with an outer rubber sleeve. The snap fastener includes a snap fastener connection part, and a strain cavity is drilled in the snap fastener connection part. A fixing post is fixedly connected in the strain cavity. The end of the connecting cable away from the take-up box passes through the snap fastener and extends into the strain cavity. The outer rubber sleeve of the part of the connecting cable located in the strain cavity is peeled off. The parts of the main traction cable and the auxiliary traction cable located in the strain cavity are both fixedly connected to the snap fastener connection part. The length of the part of the auxiliary traction cable located in the strain cavity is much longer than the length of the main traction cable located in the strain cavity.

[0006] Even if the traction cable breaks during the handling of the workpiece under fatigue stress, the auxiliary traction cable can prevent the workpiece from falling directly onto the CNC machine tool, thus minimizing irreversible mechanical damage to the CNC machine tool.

[0007] Furthermore, multiple limiting posts are fixedly connected inside the strain chamber. The end of the connecting cable away from the winding box passes through multiple limiting posts in sequence and is fixedly connected to the fixed pile. The multiple limiting posts are used to straighten the auxiliary traction cable located inside the strain chamber, so that the auxiliary traction cable located inside the strain chamber is not easy to self-tangle and knot, and is not easy to affect the normal function of the auxiliary traction cable.

[0008] Furthermore, a pre-made groove is chiseled on the side wall of the limiting post. The depth of the pre-made groove is one-third of the diameter of the limiting post. After the auxiliary traction cable takes effect, the weight of the workpiece to be processed can quickly break the limiting post, so that the auxiliary traction cable located in the strain chamber can be straightened.

[0009] Furthermore, the outer rubber sleeve is made of elastic material, and the outer wall of the outer rubber sleeve is engraved with anti-slip texture, so that the connecting cable is not easily scratched during the hoisting of the workpiece.

[0010] Furthermore, when using a gantry crane to move workpieces, the height of the workpieces lifted off the top of the CNC machine tool base must be greater than the length of the auxiliary traction cable located in the strain chamber, so that the auxiliary traction cable can be effective.

[0011] Optionally, an impact-resistant spherical shell is also fixedly connected to the outer wall of the auxiliary traction cable. The impact-resistant spherical shell is made of high-hardness material. When the impact-resistant spherical shell is subjected to external pressure, it is easy to break into sharp fragments. When the impact-resistant spherical shell moves to the opening of the strain chamber, it will be squeezed and broken by the opening. At the same time, it will cause the straightening process of the auxiliary traction cable to stop, and the impact force received by the straightening of the auxiliary traction cable will be dispersed multiple times, so that the auxiliary traction cable is not easy to break directly under the impact force generated during the fall of the workpiece.

[0012] Furthermore, the buckle connection has a break groove that matches the position of the auxiliary traction cable, and the shape of the break groove matches the impact-resistant spherical shell, which can better crush the impact-resistant spherical shell.

[0013] Furthermore, multiple breaking pressure plates are fixedly connected to the inner wall of the breaking groove. The strength of the breaking pressure plates is higher than that of the impact-resistant sphere, making the impact-resistant sphere easier to break and less likely to cause blockage or jamming of the connecting cable.

[0014] Furthermore, the impact-resistant sphere is filled with a filling bladder containing fluorescent pigment. When the impact-resistant sphere breaks, the sharp fragments formed will cut the filling bladder, causing the fluorescent pigment to spill out and flow down the auxiliary traction cable, serving as a warning and preventing defective connecting cables and buckles from being used.

[0015] Furthermore, the solvent for the fluorescent pigment is a volatile liquid, which allows the fluorescent pigment to dry quickly and solidify on the surface of the auxiliary traction cable, serving as a marking function.

[0016] Compared to existing technologies, the advantages of this application are:

[0017] In this application, when using a winding box and connecting cable to transport the workpiece to be processed, if the force-bearing traction cable breaks, the weight of the workpiece to be processed is transferred to the auxiliary traction cable, which temporarily lifts the workpiece to be processed, making it less likely for the workpiece to fall directly onto the surface of the CNC machine tool base and less likely to cause damage to the CNC machine tool base.

[0018] Meanwhile, both the impact-resistant spherical shell and the filling bladder are optional components. The impact-resistant spherical shell can pause the straightening process of the auxiliary traction cable, dispersing the impact force received by the auxiliary traction cable multiple times. This makes it less likely for the auxiliary traction cable to break directly under the impact force generated during the fall of the workpiece. The rupture of the filling bladder will cause the fluorescent pigment to overflow and flow down the auxiliary traction cable, providing a warning and preventing the connection cable and buckle from being used with defects. This increases the safety of CNC machine tool operation and reduces the likelihood of destructive accidents. Attached Figure Description

[0031] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application. Example

[0032] This invention provides a gantry-type moving CNC machine tool; please refer to [link / reference]. Figure 1-6 The system includes a CNC machine tool base 1, with a pair of matching electric slide rails 3 carved into a pair of side walls of the CNC machine tool base 1. A gantry crane 2 is installed above the CNC machine tool base 1. The gantry crane 2 includes a 201, on which a pair of electric sliders, each matching the position of the two electric slide rails 3, are fixedly connected. The electric sliders are slidably connected within the electric slide rails 3. A control terminal 4 is fixedly connected to the side wall of the gantry crane 2. A 202 is carved into the 201, facing the upper surface of the CNC machine tool base 1. A winding box 6 is slidably connected within the 202. A pair of connecting cables 7 are fixedly connected within the winding box 6. Each end of the two connecting cables 7 away from the winding box 6 is fixedly connected to a buckle 8. A workpiece 5 is placed on the upper end of the CNC machine tool base 1. The end of one connecting cable 7 away from the winding box 6 passes through... The workpiece 5 is fixed to another connecting cable 7 by a buckle 8. The connecting cable 7 includes a force-bearing traction cable 702 and an auxiliary traction cable 703. The auxiliary traction cable 703 has a higher structural strength than the force-bearing traction cable 702. The outer sides of the force-bearing traction cable 702 and the auxiliary traction cable 703 are covered with an outer rubber sleeve 701. The buckle 8 includes a buckle connection part 801. A strain cavity is drilled in the buckle connection part 801. A fixing post 802 is fixedly connected in the strain cavity. The end of the connecting cable 7 away from the winding box 6 passes through the buckle 8 and extends into the strain cavity. The outer rubber sleeve 701 of the part of the connecting cable 7 located in the strain cavity is peeled off. The parts of the force-bearing traction cable 702 and the auxiliary traction cable 703 located in the strain cavity are fixedly connected to the buckle connection part 801.

[0033] In this solution, the movement of the gantry crane 2 along the electric slide rail 3 and the movement of the winding box 6 within 202 are both controlled by the control terminal 4. Furthermore, auxiliary equipment is required during the aforementioned movement process. These are all technologies known to those skilled in the art, and therefore are not disclosed in detail in this application. Those skilled in the art can design reasonably based on existing technology.

[0034] In addition, a motor is also provided inside the winding box 6 for winding the connecting cable 7 and thus controlling the length of the connecting cable 7 on the outside of the winding box 6. The motor is controlled by the control terminal 4, which is also known to those skilled in the art. Those skilled in the art can design it reasonably based on the existing technology.

[0035] It is worth noting that, for ease of demonstration, the various structures in this application are not drawn strictly to scale, and those skilled in the art can make reasonable adjustments according to actual needs.

[0036] Please see Figure 6-710. Multiple limiting posts 803 are fixedly connected inside the strain chamber. The end of the connecting cable 7 away from the winding box 6 passes through the multiple limiting posts 803 in sequence and is fixedly connected to the fixing post 802. The multiple limiting posts 803 are used to straighten the auxiliary traction cable 703 located in the strain chamber, so that the auxiliary traction cable 703 located in the strain chamber is not prone to self-tangling and knotting, and is not likely to affect the normal function of the auxiliary traction cable 703. A pre-made groove 804 is carved on the side wall of the limiting post 803. The depth of the pre-made groove 804 is one-third of the diameter of the limiting post 803. After 03 takes effect, the weight of the workpiece 5 can quickly break the limit post 803, allowing the auxiliary traction cable 703 located in the strain chamber to straighten. The outer rubber sleeve 701 is made of elastic material, and the outer wall of the outer rubber sleeve 701 is engraved with anti-slip texture, so that the connecting cable 7 is not easily scratched during the hoisting of the workpiece 5. When using the gantry crane 2 to move the workpiece 5, the height of the workpiece 5 from the top of the CNC machine tool base 1 must be greater than the length of the auxiliary traction cable 703 located in the strain chamber, so that the auxiliary traction cable 703 can be ensured to take effect.

[0037] In this application, when using the winding box 6 and connecting cable 7 to transport the workpiece 5, when the connecting cable 7 is working normally, since the auxiliary traction cable 703 is not taut, the weight of the workpiece 5 is only pulled by the force traction cable 702. During the normal operation of the force traction cable 702, stress fatigue will occur, affecting the structural strength of the force traction cable 702. After long-term operation, the weight that the force traction cable 702 can bear will gradually decrease. Therefore, even during the process of hoisting the workpiece 5 with the correct weight, the force traction cable 702 may break. Since the auxiliary traction cable 703 does not need to bear the weight of the workpiece 5, stress fatigue does not occur in the workpiece 5, and its own structural strength will not change. When the force traction cable 702 breaks, the weight of the workpiece 5 is transferred to the auxiliary traction cable 703, which temporarily hoists the workpiece 5, making it less likely for the workpiece 5 to fall directly onto the surface of the CNC machine tool base 1 and less likely to cause damage to the CNC machine tool base 1. Example

[0038] This invention provides a gantry-type moving CNC machine tool; please refer to [link / reference]. Figure 6-9An impact-resistant spherical shell 704 is fixedly connected to the outer wall of the auxiliary traction cable 703. The impact-resistant spherical shell 704 is made of a high-hardness material. When the impact-resistant spherical shell 704 is subjected to external pressure, it is prone to breakage, forming sharp fragments. When the impact-resistant spherical shell 704 moves to the opening of the strain chamber, it will be squeezed and broken by the opening. At the same time, it will cause the straightening process of the auxiliary traction cable 703 to stop, dispersing the impact force on the straightening of the auxiliary traction cable 703 multiple times. This makes the auxiliary traction cable 703 less likely to break directly under the impact force generated during the falling of the workpiece 5. The snap-fit ​​connection part 801 is chiseled with a breaking groove 805 that matches the position of the auxiliary traction cable 703, and the shape of the breaking groove 805 matches the impact-resistant spherical shell 704. The shock-resistant spherical shell 704 can be broken more easily. Multiple breaking pressure plates 806 are fixedly connected to the inner wall of the breaking groove 805. The strength of the breaking pressure plates 806 is higher than that of the shock-resistant spherical shell 704, making the shock-resistant spherical shell 704 easier to break and less likely to cause blockage or jamming of the connecting cable 7. The shock-resistant spherical shell 704 is filled with a filling bladder 705, which is filled with fluorescent pigment. The sharp fragments formed after the shock-resistant spherical shell 704 breaks will cut the filling bladder 705, causing the fluorescent pigment to spill out and flow down the auxiliary traction cable 703, giving a warning and preventing the connecting cable 7 and the buckle 8 from being used with defects. The solvent of the fluorescent pigment is a volatile liquid, which allows the fluorescent pigment to dry quickly and solidify on the surface of the auxiliary traction cable 703, serving as a marking function.

[0039] The impact-resistant spherical shell 704 and the filling bladder 705 in this solution are optional components. The impact-resistant spherical shell 704 can pause the straightening process of the auxiliary traction cable 703, dispersing the impact force on the auxiliary traction cable 703 multiple times. This makes the auxiliary traction cable 703 less likely to break directly under the impact force generated during the fall of the workpiece 5. The rupture of the filling bladder 705 will cause the fluorescent pigment to overflow and flow down the auxiliary traction cable 703, providing a warning and preventing the connecting cable 7 and buckle 8 from operating with defects. This increases the safety of CNC machine tool operation and reduces the likelihood of destructive accidents.

[0040] The above description is only the best implementation method adopted in this application in combination with current practical needs, but the scope of protection of this application is not limited thereto.
