Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool automated processing equipment technology, and in particular to an automatic loading and unloading robot for CNC machine tool processing. Background Technology

[0002] A CNC machine tool is an automated machine tool that integrates computer technology, automatic control technology, precision measurement technology, and mechanical design and manufacturing technology. It uses a computer control system to read and execute pre-programmed machining programs, control the movement of each axis of the machine tool, the spindle speed, the selection and replacement of cutting tools, the switching of coolant, etc., thereby automatically completing the machining of parts.

[0003] In CNC machine tool processing, traditional loading and unloading methods mostly rely on manual operation, which has many problems: on the one hand, manual operation is inefficient, as workers need to frequently move workpieces to the machine tool table for clamping and unloading after processing, which consumes a lot of time and is difficult to meet the needs of efficient production in modern manufacturing. On the other hand, manual operation poses certain safety hazards. When loading and unloading is performed during machine tool operation, workers are prone to injury due to misoperation or sudden machine tool failure. Therefore, an automatic loading and unloading robot for CNC machine tool processing is proposed to solve the above problems. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide an automatic loading and unloading robot for CNC machine tool processing, which can solve the technical problem of low efficiency of existing manual operation and the time-consuming and labor-intensive process of workers having to frequently move workpieces to the machine tool worktable for clamping.

[0006] To solve the above technical problems, this utility model provides an automatic loading and unloading robot for CNC machine tool processing, which adopts the following technical solution: it includes a CNC machine base, a conveyor belt is fixedly installed on the upper end of the CNC machine base and a PLC control panel is fixedly installed on the outer wall of the CNC machine base, a guide frame is fixedly installed on the rear side of the CNC machine base and an adjustment structure is installed on the front side of the guide frame;

[0007] A clamping structure is provided above the adjustment structure. The clamping structure includes a guide sleeve. A positioning plate is fixedly provided on the outer wall of the guide sleeve. A clamping motor is fixedly provided at the bottom of the positioning plate. A main gear is fixedly connected to the output end of the clamping motor. A first driven gear is meshed with the outer wall of the main gear. A second driven gear is meshed with the outer wall of the first driven gear. Guide plates are fixedly connected to the outer walls of both the first and second driven gears. Guide plates of the same size are rotatably connected to the bottom of the positioning plate at positions corresponding to the two driven gears. Positioning shafts are rotatably connected inside the two sets of guide plates, and both positioning shafts are fixedly installed inside the two clamping frames.

[0008] Optionally, a dust cover is fixedly installed above the positioning plate, and the main gear, the first driven gear and the second driven gear are rotatably mounted on the upper part of the positioning plate. Two sets of positioning shafts are fixedly installed inside the two clamping frames.

[0009] Optionally, another set of positioning shafts has two sets of auxiliary side plates rotatably connected to its outer wall, and the other ends of the two sets of auxiliary side plates are rotatably mounted on the upper and lower ends of the positioning plate. The positions of the two clamping frames are matched, and the surface of the clamping frames is provided with threaded grooves.

[0010] Optionally, an adjusting motor is fixedly installed inside the guide frame, and a threaded screw is fixedly connected to the output end of the adjusting motor. A nut seat is threadedly connected to the outer wall of the threaded screw, and a support plate is fixedly installed on the outer wall of the nut seat. Guide sliders are fixedly connected to the upper and lower ends of the outer wall of the nut seat, and the guide sliders are slidably connected inside the guide frame.

[0011] Optionally, the adjustment structure includes a base fixedly installed at the bottom of the support plate. A rotary motor is fixedly installed inside the base, and a rotating platform is fixedly connected to the upper end of the rotary motor. A main arm is rotatably connected to the upper end of the rotating platform. A positioning column and a fixed shaft are fixedly installed inside the main arm. A second limiting seat and a third limiting seat are symmetrically fixedly connected to the outer wall of the positioning column.

[0012] Optionally, the outer walls of the second and third limiting seats are respectively rotatably connected to a first cylinder and a second cylinder. The bottom of the first cylinder is rotatably installed inside the first limiting seat, and the first limiting seat is fixedly installed on the rotating platform. One end of the second cylinder is rotatably connected to the bottom of the auxiliary arm, and one end of the auxiliary arm is rotatably connected to the inside of the fixed shaft.

[0013] In summary, this utility model has at least one of the following beneficial effects: 1. By setting up a clamping structure, the main gear is driven to rotate by driving the clamping motor, which in turn drives the first driven gear to mesh with the second driven gear. This causes the first driven gear and the second driven gear to synchronously drive the positioning shafts on the two sets of guide plates to move relative to each other, thereby driving the clamping frames on the two positioning shafts to move relative to each other to clamp and position goods of different sizes. The robot can adapt to clamping workpieces of different sizes, enhancing the versatility of the robot and meeting diverse processing needs.

[0014] Simultaneously, by adjusting the structure, the nut seat on the threaded screw is moved stably by the driving adjustment motor, causing the nut seat to move relative to the base on the support plate. The rotary motor inside the base drives the main arm on the rotating table to rotate. At the same time, the first cylinder drives the positioning column on the second limit seat to move downward according to the position of the goods, thereby driving the main arm to move lower and closer to the goods. At the same time, the second cylinder on the positioning column drives the auxiliary arm to rotate and cooperate within the fixed axis, thereby moving the robot arm on the auxiliary arm downward to align with the position of the goods. Then, by cooperating with the robot arm to clamp and load / unload, the automatic loading and unloading of workpieces is realized without manual intervention, which greatly improves the processing efficiency of CNC machine tools, reduces the production cycle, avoids manual loading and unloading operations during machine operation, and reduces the risk of worker injury.

[0022] 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.

[0023] The following is in conjunction with the appendix Figure 1 —5. This utility model will be described in further detail.

[0024] Reference Figure 1-5 In this embodiment, in order to solve the technical problem that the existing manual operation is inefficient and workers need to frequently move the workpiece to the machine tool table for clamping, which is time-consuming and labor-intensive, this utility model discloses an automatic loading and unloading robot for CNC machine tool processing.

[0025] It includes a CNC machine base 1, a conveyor belt is fixedly installed on the upper end of the CNC machine base 1 and a PLC control panel 2 is fixedly installed on the outer wall of the CNC machine base 1, a guide frame 3 is fixedly installed on the rear side of the CNC machine base 1 and an adjustment structure 4 is installed on the front side of the guide frame 3.

[0026] A clamping structure 5 is provided above the adjusting structure 4. The clamping structure 5 includes a guide sleeve 52. A positioning plate 54 is fixedly provided on the outer wall of the guide sleeve 52. A clamping motor 53 is fixedly provided at the bottom of the positioning plate 54. A main gear 55 is fixedly connected to the output end of the clamping motor 53. A first driven gear 56 is meshed with the outer wall of the main gear 55. A second driven gear 57 is meshed with the outer wall of the first driven gear 56. Guide plates 58 are fixedly connected to the outer walls of both the first driven gear 56 and the second driven gear 57. Guide plates 58 of the same size are rotatably connected to the bottom of the positioning plate 54 at the corresponding positions of the two driven gears. Positioning shafts 591 are rotatably connected inside the two sets of guide plates 58, and both positioning shafts 591 are fixedly installed inside the two clamping frames 59.

[0027] Specifically, a dust cover 51 is fixedly installed above the positioning plate 54, and the main gear 55, the first driven gear 56 and the second driven gear 57 are rotatably installed on the upper end of the positioning plate 54. Two sets of positioning shafts 591 are fixedly installed inside the two clamping frames 59.

[0028] By setting a dust cover 51 on the positioning plate 54, multiple gears can be protected and prevented from being directly exposed to the air, which could cause oxidation and other problems. One end of the first driven gear 56 and the second driven gear 57 are both fixedly provided with guide plates 58, which causes the clamping frame 59 fixed on the positioning shaft 591 on the guide plate 58 to move relative to each other when the two driven gears rotate.

[0029] Specifically, the outer wall of another set of positioning shafts 591 is rotatably connected to two sets of auxiliary side plates 581, and the other ends of the two sets of auxiliary side plates 581 are rotatably installed on the upper and lower ends of the positioning plate 54. The positions of the two clamping frames 59 are matched, and the surface of the clamping frame 59 is set with a threaded groove.

[0030] By setting two sets of auxiliary side plates 581 at both the upper and lower ends of the positioning plate 54, the relative movement of the clamping frame 59 makes it more stable for clamping and loading goods, protecting the goods from slippage and damage. The inner wall of the clamping frame 59 is set into a groove shape to facilitate mutual friction while clamping the goods, thereby improving clamping stability.

[0031] Specifically, an adjusting motor 31 is fixedly installed inside the guide frame 3. A threaded screw 32 is fixedly connected to the output end of the adjusting motor 31. A nut seat 33 is threadedly connected to the outer wall of the threaded screw 32, and a support plate is fixedly installed on the outer wall of the nut seat 33. Guide sliders 34 are fixedly connected to the upper and lower ends of the outer wall of the nut seat 33, and the guide sliders 34 are slidably connected inside the guide frame 3.

[0032] The drive motor 31 drives the nut seat 33 on the threaded screw 32 to move, which in turn causes the nut seat 33 to move the robot arm on the support plate stably, making it easy to load and unload goods at different positions and to adjust the robot arm.

[0033] Specifically, the adjustment structure 4 includes a base 41 fixedly installed at the bottom of the support plate. A rotary motor is fixedly installed inside the base 41, and a rotating platform is fixedly connected to the upper end of the rotary motor. A main arm 43 is rotatably connected to the upper end of the rotating platform. A positioning column 44 and a fixed shaft 430 are fixedly installed inside the main arm 43. A second limiting seat 46 and a third limiting seat 47 are symmetrically fixedly connected to the outer wall of the positioning column 44.

[0034] The first cylinder 42 is rotatably mounted on the second limit seat 46 and the first limit seat 45 at one end and the bottom, respectively. At the same time, the main arm 43 is rotatably mounted on the rotating platform. The bottom of the second cylinder 48 is rotatably mounted on the third limit seat 47, and one end of the second cylinder 48 is rotatably connected to the bottom of the auxiliary arm 49.

[0035] Specifically, the outer walls of the second limiting seat 46 and the third limiting seat 47 are respectively rotatably connected to the first cylinder 42 and the second cylinder 48. The bottom of the first cylinder 42 is rotatably installed inside the first limiting seat 45, and the first limiting seat 45 is fixedly installed on the rotating platform. One end of the second cylinder 48 is rotatably connected to the bottom of the auxiliary arm 49, and one end of the auxiliary arm 49 is rotatably connected to the inside of the fixed shaft 430. One end of the guide sleeve 52 is fixedly connected to the inside of the auxiliary arm 49.

[0036] The first cylinder 42 drives the main arm 43 to adjust the angle, and the second cylinder 48 drives the robot arm on the auxiliary arm 49 to adjust the angle. At the same time, a rotary motor is installed in the base 41 to facilitate the robot arm to rotate in all directions, so that the robot arm can be stably adjusted to the side of the goods for easy loading and unloading.

[0037] The specific working principle is as follows: First, the operator presets the robot arm parameters and path in advance on the PLC control panel 2. Then, when the goods approach the CNC machine tool 1, the adjusting motor 31 in the drive guide frame 3 works, causing the adjusting motor 31 to drive the nut seat 33 on the threaded screw 32 to move stably, causing the nut seat 33 to drive the base 41 on the support plate to move relative to it. When it moves close to the goods, the rotating motor in the drive base 41 drives the main arm 43 on the rotating table to rotate. At the same time, the first cylinder 42 drives the positioning column 44 on the second limit seat 46 to move downward according to the position of the goods, thereby driving the main arm 43 to move downward and close to the goods. At the same time, the second cylinder 48 on the positioning column 44 drives the auxiliary arm 49 to rotate and cooperate within the fixed shaft 430, thereby moving the robot arm on the auxiliary arm 49 downward, so as to align with the position of the goods, making it easy to stably adjust the robot arm to the position corresponding to the goods, and realizing the adjustment stability of the robot arm.

[0038] When the robotic arm is positioned relative to the goods, the main gear 55 is driven to rotate by the clamping motor 53. This causes the main gear 55 to drive the first driven gear 56 to mesh with the second driven gear 57. This causes the first driven gear 56 and the second driven gear 57 to synchronously drive the positioning shafts 591 on the two sets of guide plates 58 to move relative to each other. This causes the clamping frames 59 on the two positioning shafts 591 to move relative to each other to clamp and position goods of different sizes. At the same time, the two clamping frames 59 cooperate with the auxiliary side plate 581 when they move relative to each other, which improves the clamping stability of the clamping frames 59. This realizes automatic loading and unloading of goods and avoids the problems of time-consuming and labor-intensive manual operation.
