Technical Field

[0001] The invention relates to the technical field of anti-collision of a CNC lathe body door, and in particular to an impact buffering protection device for a CNC lathe door edge. Background Art

[0002] The CNC lathe body is one of the most widely used CNC machine tools. It is mainly used for cutting and processing of inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer conical surfaces of arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads, and can also perform grooving, drilling, reaming, reaming and boring, etc.

[0003] In order to ensure the accuracy of processing and prevent the operator from being harmed by broken tools and flying debris, the current CNC lathe bodies are generally equipped with slide rail protection doors.

[0004] However, since the protective door is opened and closed very frequently, the double-side doors are easily hit when closing, causing the protective door to deform, which increases the failure rate and reduces the service life of the protective door. Summary of the invention

[0005] In view of the above problems, the present invention provides an impact buffering protection device for the door edge of a CNC lathe, which can provide a buffering force to the protective door of the lathe body to prevent it from being deformed due to frequent impacts and reduce the failure rate of the protective door during use.

[0006] In order to achieve the above object, the present invention is achieved through the following technical solutions:

[0007] A door edge impact buffer protection device for a numerically controlled lathe is applied to a numerically controlled lathe body. The lathe body is provided with two protective doors, which are respectively slidably connected to two sides of the lathe body, and further includes:

[0008] The mounting plate is symmetrically arranged at the merging position of one side of the two protective doors.

[0009] The rotating part is rotatably connected to a position on one side of the mounting plate close to the protective door, and the rotating parts on both sides cooperate with each other.

[0010] The guide wheel is rotatably mounted on the end of the rotating member, and the guide wheels on both sides are used to abut against each other.

[0011] The elastic member is installed on the side of the rotating member.

[0012] Furthermore, a torsion spring is connected to the rotating connection of the rotating member, which provides elastic force for the rotating member. A ratchet is fixed to the rotating connection of the rotating member. A lock is provided at the bottom of the mounting plate, and a spring is sleeved on the lock to provide elastic force for the lock.

[0013] Furthermore, the installation position of the locking element corresponds to the installation position of the ratchet, and the locking element is used to lock the ratchet.

[0014] Furthermore, a cylinder is installed on the outside of the lathe body, a push plate is fixedly connected to the output end of the cylinder, and connecting rods are slidably connected to both sides of the push plate.

[0015] Furthermore, the two connecting rods are symmetrically and staggeredly slidably connected to the bottom of the pushing plate, and the bottom of the pushing plate is provided with a sliding groove adapted to the movable track on one side opposite to the position of the two connecting rods.

[0016] Furthermore, the bottom of the locking element is fixedly connected to the connecting rod, and the pushing plate is used to push the connecting rod to unlock the locking element.

[0017] Furthermore, the bottom of the mounting plate is slidably connected to a corresponding sliding clamp, and the bottom of the sliding clamp is clamped on the connecting rod.

[0018] Furthermore, a card slot adapted to the movable track corresponding to the position of the sliding card is provided on the connecting rod.

[0019] Furthermore, a cavity adapted to a movable track corresponding to the position of the rotating member is provided on one side of the mounting plate.

[0020] Furthermore, a mounting groove adapted to a movable trajectory corresponding to the position of the guide wheel is provided at the top end of the rotating member, and the mounting positions of the two guide wheels correspond.

At this time, the torsion springs provide elastic force to buffer the impact force generated when closing the doors. After the protective doors are slowly closed, the rotating parts on both sides rotate to a vertical state and fit each other, thereby providing a buffering force for the protective doors of the lathe body to prevent deformation due to frequent impacts and reduce the failure rate of the protective doors during use. Furthermore, through the combination of torsion springs and rotating parts, an effective buffering effect is provided for the protective doors, and when the protective doors are hit, the impact force can be reduced to protect the lathe body structure and the safety of the operator.

[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] like Figure 1-Figure 5 As shown, the embodiment provides a door edge impact buffer protection device for a CNC lathe body 1, which is applied to the CNC lathe body 1. The lathe body 1 is provided with two protective doors 2, and the two protective doors 2 are respectively slidably connected to the two sides of the lathe body 1, and also includes:

[0030] The mounting plate 3 is symmetrically arranged at the merging position of the two protective doors 2 on one side.

[0031] The rotating member 4 is rotatably connected to a position on one side of the mounting plate 3 close to the protective door 2, and the rotating members 4 on both sides cooperate with each other.

[0032] The guide wheel 9 is rotatably mounted on the end of the rotating member 4, and the guide wheels 9 on both sides are used to abut against each other.

[0033] The elastic member 14 is installed on the side of the rotating member 4.

[0034] Specifically, a torsion spring 5 is connected to the rotating connection of the rotating member 4, which provides elastic force for the rotating member 4. A ratchet 6 is fixed to the rotating connection of the rotating member 4. A lock 7 is provided at the bottom of the mounting plate 3. A spring 8 is sleeved on the lock 7 to provide elastic force for the lock 7.

[0035] Furthermore, the elastic member 14 further improves the buffering effect and further reduces the noise during closing the protective door 2. The addition of the sliding clamp 13 and the elastic member 14 further ensures the stable connection between the connecting rod 12 and the rotating member 4, thereby improving the reliability of the overall system.

[0036] Furthermore, the setting of the guide wheels 9 on both sides facilitates the rotation of the rotating part 4, effectively reduces noise, and improves the stability of the protective door 2 during the closing process. The design of the guide wheels 9 enables the rotating parts 4 on both sides to abut against each other and transition smoothly during the closing process, reducing the generation of vibration and noise, and providing a more comfortable working environment for the operator.

[0037] The present invention provides a rotating part 4 on the protective doors 2 on both sides, and provides elastic force for the rotating part 4 through the torsion spring 5. When the protective doors 2 on both sides are closed, the two protective doors 2 approach each other until the two rotating parts 4 abut against each other and rotate. At this time, the torsion spring 5 provides elastic force to buffer the impact force generated when the door is closed. After the protective door 2 is slowly closed, the rotating parts 4 on both sides rotate to a vertical state and fit each other, thereby providing a buffering force for the protective door 2 of the lathe body 1 to prevent it from being deformed due to frequent collisions, thereby reducing the failure rate of the protective door 2 during use. Furthermore, through the combination of the torsion spring 5 and the rotating part 4, an effective buffering effect is provided for the protective door 2. When the protective door is hit, the impact force can be reduced to protect the lathe body structure and the safety of the operator.

[0038] Embodiment 1

[0039] The impact buffer protection device of the CNC lathe body door has added an automatic reset mechanism. Specifically, a magnetic strip is installed on the inner edge of each side of the protective door, and a magnetic adsorption block is set at the corresponding position of the lathe body door frame. When the protective door is opened due to external impact, the magnetic strip is separated from the magnetic adsorption block, and the protective door slowly opens to the maximum angle under the action of the torsion spring. Once the external force disappears, the attraction of the magnetic strip will assist the protective door to close automatically, and the elastic force of the torsion spring will achieve precise reset, ensuring the safe closure of the lathe body operation area, further improving the operation efficiency and reducing manual intervention, reducing the risk of misoperation.

[0040] Specifically, the installation position of the locking member 7 corresponds to the installation position of the ratchet 6 , and the locking member 7 is used to lock the ratchet 6 .

[0041] Furthermore, the ratchet 6, the lock 7 and the spring 8 realize the unidirectional rotation of the rotating member 4, which does not affect the normal closing of the two protective doors 2 while achieving the effect of buffering the impact force, and has good practicality. Furthermore, the addition of the ratchet 6, the lock 7 and the spring 8 enables the protective door 2 to be firmly locked in the closed state to prevent accidental opening during the processing, thereby ensuring the processing accuracy and safety.

[0042] Specifically, a cylinder 10 is installed on the outside of the lathe body 1 , a push plate 11 is fixedly connected to the output end of the cylinder 10 , and connecting rods 12 are slidably connected to both sides of the push plate 11 .

[0043] Furthermore, the cylinder 10 drives the push plate 11 to move downward, and then drives the two connecting rods 12 to move downward synchronously. The connecting rod 12 drives the lock 7 to move downward and separate from the ratchet 6, thereby realizing synchronous automatic unlocking operation on both sides. Furthermore, the design of the cylinder 10, the push plate 11 and the connecting rod 12 realizes the automatic unlocking and opening of the protective door 2, reduces manual operation, and improves operating efficiency. In an emergency, the push plate 11 can be quickly pushed through the reverse operation of the cylinder 10, and then the lock is unlocked through the connecting rod 12, so that the protective door 2 can be quickly opened, thereby improving the emergency response speed.

[0044] Specifically, the two connecting rods 12 are symmetrically and staggeredly slidably connected to the bottom of the pushing plate 11, and the bottom of the pushing plate 11 is provided with a sliding groove adapted to the movable track of the two connecting rods 12 on the opposite side.

[0045] Furthermore, when the protective door 2 is closed, the two connecting rods 12 are close to each other, thereby improving the flexibility and stability of the movement of the two connecting rods 12 .

[0046] Specifically, the bottom of the locking member 7 is fixedly connected to the connecting rod 12 , and the pushing plate 11 is used to push the connecting rod 12 to unlock the locking member 7 .

[0047] Furthermore, automatic unlocking and opening of the protective door 2 is achieved, which reduces manual operations and improves operating efficiency.

[0048] Specifically, the bottom of the mounting plate 3 is slidably connected to a corresponding sliding clamp 13 , and the bottom of the sliding clamp 13 is clamped on the connecting rod 12 .

[0049] Furthermore, the sliding card 13 is used for manual unlocking operation, and the connecting rod 12 can be pulled downward, and then the sliding card 13 is pushed to clamp the connecting rod 12, which further improves practicality for manual unlocking operation.

[0050] Specifically, a cavity adapted to the movable track corresponding to the position of the rotating member 4 is provided on one side of the mounting plate 3 , so as to improve the flexibility of the rotation of the rotating member 4 .

[0051] Specifically, the top of the rotating part 4 is provided with an installation groove adapted to the movable trajectory corresponding to the position of the guide wheel 9, and the installation positions of the two guide wheels 9 correspond. Furthermore, when the two protective doors 2 are closed, the two guide wheels 9 abut against each other, and the guide wheels 9 start to rotate, driving the rotating parts 4 on both sides to rotate, and then the two protective doors 2 slowly close, thereby realizing the protection of the two protective doors 2 being closed.

[0052] Embodiment 2

[0053] This embodiment adopts a multi-stage torsion spring adjustment buffer system. The torsion spring connected to each rotating part is designed as a multi-stage structure with adjustable torque. Through simple knob or screw adjustment, the appropriate elastic force can be set according to the protective door of different materials or weights. In addition, a damper is added to slow down the impact speed when the protective door 2 is closed, further protect the lathe body structure and reduce noise. Furthermore, when the material of the protective door 2 changes, the weight difference is large, or the opening and closing speed needs to be accurately controlled, the flexibility and applicability of the equipment are improved.

[0054] Embodiment 3

[0055] In this embodiment, non-contact distance sensors and pressure sensors are installed at the edge of the protective door 2 and the door frame of the lathe body to monitor the status of the protective door 2 and the impact force it receives in real time. When an abnormal impact is detected or the protective door 2 is not completely closed, the sensor will immediately trigger the alarm system and automatically stop the machine operation through the control system of the CNC lathe body to ensure the safety of the operator. At the same time, the system also has remote monitoring and fault diagnosis functions, and can transmit the protective door status data to the management terminal in real time through the network, which is convenient for remote monitoring and maintenance, further improving the overall safety level of the workshop, reducing the risk of accidents, and improving production efficiency.

[0056] How it works

[0057] When processing the workpiece, the protective doors 2 on both sides are closed. Whether the protective doors 2 are electrically driven or manually moved by the operator, the device can be installed and applied. The two protective doors 2 are close to each other until the two guide wheels 9 abut against each other, and the guide wheels 9 start to rotate, driving the rotating parts 4 on both sides to rotate. At this time, the torsion spring 5 is compressed, the ratchet 6 rotates synchronously, and the lock part 7 realizes one-way locking. The impact force is buffered by the force of the torsion spring 5 until the two protective doors 2 are slowly closed. When the protective doors 2 are completely closed, the two rotating parts 4 rotate to a vertical state, and the two sides The elastic member 14 fits tightly. When the protective door 2 is to be opened, the cylinder 10 is operated to move the push plate 11 downward, and the push plate 11 drives the connecting rod 12 and the lock member 7 downward, and the lock member 7 is separated from the ratchet 6. At this time, the spring 8 is compressed, the ratchet 6 is unlocked, and the protective doors 2 on both sides move away from each other. Due to the action of the torsion spring 5, the ratchet 6 and the rotating member 4 rotate to reset, and can also be manually unlocked. Press the connecting rod 12 downward to separate the lock member 7 from the ratchet 6, and then push the sliding card 13 so that the sliding card 13 limits the connecting rod 12.

[0058] This specific embodiment is merely an explanation of the invention and is not a limitation of the invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as they are within the scope of protection of the invention, they are protected by patent law.
