Description

Technical Field

[0001] This utility model belongs to the technical field of CNC machine tools, specifically relating to an automatic loading and unloading mechanism for a CNC gear hobbing machine. Background Technology

[0002] The automatic loading and unloading mechanism for CNC gear hobbing machines is a device used to automate the loading and unloading process of CNC gear hobbing machines. Its main function is to automatically feed the workpiece into the machine for processing and remove the workpiece after processing. This automatic loading and unloading mechanism can greatly improve production efficiency, reduce labor costs, and reduce human-machine contact, thereby improving safety. However, if the lifting mechanism experiences jerking or uneven operation while lifting the material to be processed, it can cause the material to shake, become misaligned, or even fall on the platen, requiring manual intervention to reset the material. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic loading and unloading mechanism for a CNC gear hobbing machine, so as to solve the problem mentioned in the background art that if the lifting mechanism is jerky or not smooth during operation, the material being processed will shake, become misaligned, or even fall off the placement plate.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic loading and unloading mechanism for a CNC gear hobbing machine, comprising a worktable and a loading and unloading mechanism body mounted on the upper part of the worktable;

[0005] A processing mechanism is provided on the left side of the main body of the loading and unloading mechanism;

[0006] The main body of the loading and unloading mechanism is equipped with a turntable;

[0007] The left and right ends of the turntable are fixedly connected with grippers on their circular outer walls. Control rods are provided on the upper side of each gripper. Drive mechanisms are fixedly connected to the left and right ends of the main body of the loading and unloading mechanism to control the opening and closing of the grippers. A lifting mechanism is provided on the right side of the main body of the loading and unloading mechanism. A feeding platform is provided on the upper side of the lifting mechanism. Raw material is provided at the center of the upper outer wall of the feeding platform. A processing wheel is provided on the right side of the processing mechanism.

[0008] A limit ring is fixedly connected to the upper outer wall of the feeding platform to restrict the placement position of the raw materials.

[0009] Preferably, the upper outer wall of the feeding platform has an upward-opening groove at its center, and a spring is fixedly connected to the lower inner wall of the groove.

[0010] Preferably, a baffle is fixedly connected to the upper outer wall of the spring, and an anti-slip pad is fixedly connected to the upper outer wall of the baffle.

[0011] Preferably, when the raw material is placed on the baffle, the upper outer wall of the anti-slip mat and the upper outer wall of the feeding platform are on the same horizontal plane, and the anti-slip mat is made of soft rubber material.

[0012] Preferably, a fixing plate is fixedly connected to the outer wall of the right end of the loading and unloading mechanism body to limit the position of the lifting mechanism, and a clamping component a is provided on the outer wall of the left end of the loading and unloading mechanism body.

[0013] Preferably, a clamping component b is provided at the center of the upper outer wall of the worktable, and a movable table is connected to the right outer wall of the processing mechanism to control the forward and backward movement of the processing wheel.

[0014] Preferably, a transverse movement mechanism is fixedly connected to the lower outer wall of the processing mechanism, and a slide rail is fixedly connected to the upper outer wall of the worktable to limit the lateral movement distance of the transverse movement mechanism.

[0015] Preferably, the drive mechanism is provided with a drive rod inside. After the drive rod moves down, it pushes the control rod on both sides to move, thereby causing the gripper to open.

[0016] Compared with the prior art, this utility model provides an automatic loading and unloading mechanism for a CNC gear hobbing machine, which has the following advantages:

[0017] By installing limit rings, the placement position of raw materials is restricted. When the robotic arm places the raw materials, they can be placed in the middle of the limit rings. When the lifting mechanism pushes the material feeding platform to move upward, it can prevent the raw materials from shaking, misaligning, or falling due to jerking during the upward movement. The limit rings can also act as a buffer during the lifting process, reducing the impact force when the raw materials come into contact with the feeding platform, further reducing the risk of damage. Because the placement of raw materials is more precise, the time spent on subsequent adjustments and repositioning due to misalignment or falling is also greatly reduced, thereby improving production efficiency. The function of the limit rings allows the machine to automatically complete the placement of raw materials, reducing human intervention and thus reducing the chance of accidents during operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-4 The automatic loading and unloading mechanism of a CNC gear hobbing machine shown includes a worktable 1 and a loading and unloading mechanism body 2 installed on the upper end of the worktable 1.

[0025] A processing mechanism 13 is provided on the left side of the main body 2 of the loading and unloading mechanism;

[0026] The main body 2 of the loading and unloading mechanism is equipped with a turntable 3 inside;

[0027] Grippers 8 are fixedly connected to the circular outer walls at both ends of the turntable 3. Control levers 9 are installed on the upper side of each gripper 8. Drive mechanisms 10 are fixedly connected to the outer walls at both ends of the loading and unloading mechanism body 2 to control the opening and closing of the grippers 8. A lifting mechanism 4 is installed on the right side of the loading and unloading mechanism body 2. A feeding platform 6 is installed on the upper side of the lifting mechanism 4. Raw material 7 is installed at the center of the upper outer wall of the feeding platform 6. A processing wheel 14 is installed on the right side of the processing mechanism 13. When loading and unloading the raw material 7, the raw material 7 is first loaded from the raw material feeder by an external robotic arm. The material 7 is clamped on the unloading platform 6. Then, the lifting mechanism 4 lifts the unloading platform 6 upwards. At the same time, the drive mechanism 10 extends the drive rod, causing the control rod 9 to control the gripper 8 to open. Then, the material 7 moves between the two grippers 8, and the drive mechanism 10 retracts the drive rod, causing the gripper 8 to return to its original position and clamp the material 7. After clamping, the lifting mechanism 4 controls the unloading platform 6 to descend and return to its original position. At the same time, the turntable 3 drives the gripper 8 to rotate backwards from the rightmost end to the leftmost end. Then, the gripper 8 descends and, under the control of the left-side drive mechanism 10, opens the gripper 8. This causes the clamping component b17 to adhere and fix the raw material 7, while the clamping component a11 moves down to fix the position of the raw material 7. The clamping components a11 and b17 rotate synchronously. At this time, the processing mechanism 13 conveys the processing wheel 14 to the right to clamp the raw material 7. During processing, the gripper 8, originally on the left, rotates to the far right, waiting to clamp the raw material 7 placed on the unloading platform 6 by the robotic arm. When the processing of the raw material 7 on the left is completed, the processing wheel 14 resets, and the clamping components a11 and b17 release the material. After the raw material 7 is completed, the left gripper 8 moves down to clamp the processed raw material 7. Under the rotation of the turntable 3, it is reset and the processed raw material 7 is released and placed on the unloading table 6. After the robotic arm takes out the processed raw material 7, a new unprocessed raw material 7 is placed on the unloading table 6. At the same time, the unprocessed raw material 7 held by the other gripper 8 moves between the clamping part a11 and the clamping part b17 for clamping and processing. The above operation can be repeated automatically to process and replace the raw material 7.

[0028] A limit ring 18 is fixedly connected to the upper outer wall of the feeding platform 6 to restrict the placement position of the raw material 7. When the raw material 7 is placed on the feeding platform 6, the position of the raw material 7 placed on the mechanical wall can be set within the limit ring 18 to restrict the placement position of the raw material 7 and reduce the frequency of shaking of the feeding platform 6 during the lifting process of the lifting mechanism 4.

[0029] like Figure 4 As shown, the upper outer wall of the feeding platform 6 has an upward-opening groove 19 inside. The lower inner wall of the groove 19 is fixedly connected to a spring 20, the upper outer wall of the spring 20 is fixedly connected to a baffle 21, and the upper outer wall of the baffle 21 is fixedly connected to an anti-slip pad 22.

[0030] After the raw material 7 is placed in the limiting ring 18, the baffle 21 is pressed down, causing the spring 20 to contract. The height is automatically adjusted according to the weight and height of the raw material 7, preventing the limiting ring 18 from being too high or too low, which would prevent the position of the raw material 7 from being stably restricted. The spring 20 can effectively absorb the impact force generated when the raw material 7 is placed, reduce the instantaneous impact during the placement process, reduce the risk of damage to the raw material 7, and rise or fall according to the actual situation to provide more flexible support. After the raw material 7 is placed, the anti-slip pad 22 can increase the friction between itself and the raw material 7, thereby preventing the raw material 7 from sliding or shifting after placement, improving the reliability and safety of placement.

[0031] like Figure 4 As shown, when the raw material 7 is placed on the baffle 21, the upper outer wall of the anti-slip mat 22 and the upper outer wall of the feeding platform 6 are on the same horizontal plane. The anti-slip mat 22 is made of soft rubber material.

[0032] The rebound force of spring 20 is set according to the weight of raw material 7. When raw material 7 is placed on baffle 21, the anti-slip pad 22 and the feeding table 6 will be on the same horizontal plane. It is also the concept that the lower end of raw material 7 is in contact with the feeding table 6. With the limit ring 18, the original effect of raw material 7 being placed on feeding table 6 is maintained.

[0033] like Figure 1 As shown, a fixed plate 5 is fixedly connected to the outer wall of the right end of the loading and unloading mechanism body 2 to limit the position of the lifting mechanism 4. A clamping component a11 is provided on the outer wall of the left end of the loading and unloading mechanism body 2. A clamping component b17 is provided at the center of the outer wall of the upper end of the worktable 1. A movable table 12 is connected to the outer wall of the right end of the processing mechanism 13 to control the forward and backward movement of the processing wheel 14.

[0034] The position of the lifting mechanism 4 is restricted by the fixed plate 5, which can stably lift and lower the feeding platform 6. When processing the raw material 7, the position of the raw material 7 is restricted by the clamping parts a11 and b17, and they can rotate synchronously to drive the raw material 7 to rotate, which assists the processing process. The processing wheel 14 can be controlled to move back and forth by the movable table 12 to process the raw material 7 in the corresponding position.

[0035] like Figure 1 As shown, a transverse movement mechanism 15 is fixedly connected to the lower outer wall of the processing mechanism 13, and a slide rail 16 is fixedly connected to the upper outer wall of the worktable 1 to limit the lateral movement distance of the transverse movement mechanism 15. A drive rod is provided inside the drive mechanism 10. After the drive rod moves down, it pushes the control rod 9 on both sides to move, thereby causing the gripper 8 to open.

[0036] During the processing of the raw material 7 by the processing wheel 14, the transverse mechanism 15 moves laterally on the slide rail 16 to drive the processing mechanism 13 and the processing wheel 14 to move laterally, thereby completing the process of the processing wheel 14 approaching the raw material 7 for processing and moving away from the raw material 7 to stop processing. When the gripper 8 is performing the gripping operation, the drive mechanism 10 extends the drive rod downward to between the two control rods 9. By pushing the two control rods 9 back and forth, the gripper 8 is driven to open. After the drive rod is retracted, the control rods 9 drive the gripper 8 to reset, thereby completing the gripping of the raw material 7.

[0037] The implementation principle of this embodiment is as follows: When loading and unloading raw material 7, the external robotic arm first clamps raw material 7 onto the unloading platform 6. Then, the lifting mechanism 4 lifts the unloading platform 6 upwards, and the drive mechanism 10 extends the drive rod, causing the control rod 9 to control the gripper 8 to open. Then, the raw material 7 moves between the two grippers 8, and the drive mechanism 10 retracts the drive rod, causing the gripper 8 to reset and clamp the raw material 7. After clamping, the lifting mechanism 4 controls the unloading platform 6 to descend and reset, and the turntable 3 drives the gripper 8 to rotate backwards from the rightmost end to the leftmost end. Then, the gripper 8 descends, and under the control of the left drive mechanism 10, the gripper 8 opens, allowing the clamping component b17 inside the raw material 7 to be adsorbed and fixed, and the clamping component a11 moves down to fix the position of the raw material 7. The clamping components a11 and b17 rotate synchronously. At this time, the processing mechanism 13 conveys the processing wheel 14 to the right to clamp the raw material 7. During the processing, the original The left-hand gripper 8 rotates to the far right, waiting to grip the raw material 7 placed on the unloading platform 6 by the robotic arm. After the raw material 7 on the left is processed, the processing wheel 14 resets, and the gripping parts a11 and b17 release the processed raw material 7. Then, the left-hand gripper 8 moves down to grip the processed raw material 7, and resets under the rotation of the turntable 3, releasing the processed raw material 7 and placing it on the unloading platform 6. After the robotic arm removes the processed raw material 7, a new unprocessed raw material 7 is placed on the unloading platform 6. At the same time, the unprocessed raw material 7 held by the other gripper 8 moves between the gripping parts a11 and b17 for gripping and processing. Repeating the above operation can automatically and repeatedly process and replace the raw material 7. When the raw material 7 is placed on the unloading platform 6, the position of the raw material 7 placed on the robotic wall can be set within the limit ring 18 to limit the placement position of the raw material 7 and reduce the frequency of shaking of the unloading platform 6 during the lifting process of the lifting mechanism 4.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
