[0002] At present, the robot arm transfer device of CNC lathe is one of the core technologies in the field of modern manufacturing. It has a profound technical background and is widely used. The device realizes precise positioning and rapid transfer of the robot arm through precise mechanical structure and control system, greatly improving processing efficiency and accuracy. With the continuous development of the manufacturing industry, the performance requirements for the robot arm transfer device are also increasing, requiring it to have higher stability, reliability and intelligence.

[0003] In the prior art, the robot arm indexing device of a CNC lathe with the authorization announcement number of CN202129455U includes a bracket, a robot arm and an indexing cylinder. The robot arm is rotatably mounted on the bracket through a bearing, and its side is connected to the indexing arm. The indexing cylinder is firmly fixed on the bracket, and its axis is vertical to the rotation axis of the robot arm in space. Two limit pins are arranged at the extended end of the piston rod of the indexing cylinder, and their axes are parallel to the rotation axis of the robot arm. The indexing arm is cleverly inserted between the two limit pins, and the robot arm can freely rotate along its rotation axis on the bracket, thereby realizing the precise flipping of the workpiece to a specific angle. By adjusting the distance between the two limit pins, the maximum rotation angle of the indexing arm can be effectively controlled. This device is not only flexible in rotation, but also can efficiently convert the linear motion of the piston rod into the rotary motion of the robot arm without the need for a complex connecting rod mechanism.

[0004] However, the patent lacks a cleaning device, and impurities such as dust and oil are easily accumulated on the track. These impurities not only affect the stability of the robot arm's operation, but may also cause increased wear of the track and shorten its service life;

[0005] In the prior art, the application publication number is: CN106393076A, a transfer device for a robot arm, which includes a fixed column, a card plate, a rotating table, a support arm and a gasket. A rotating ball is cleverly arranged on the top of the fixed column, which provides the possibility for flexible rotation of the device. A card plate is installed on the left side of the upper surface of the fixed column. A limit hole is specially designed in the center of the card plate to ensure the stability of the device during rotation. A rotating table is installed below the fixed column, so that the entire device can rotate smoothly. A fixing nut is provided at the center of the lower front surface of the rotating table, which is convenient for users to install firmly. A gear structure is carefully designed inside the fixed column, so that the robot arm can rotate more easily. In addition, the support arm is provided with socket holes, which can be easily connected with other support arms of the robot arm to realize the splicing function of multiple support arms, providing greater flexibility for industrial applications.

[0006] However, the patent lacks a cleaning device, which will lead to a decrease in the robot arm's transfer accuracy and affect the processing quality. Long-term unclean tracks may also cause mechanical failures, increase maintenance costs, and reduce production efficiency. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Please refer to 1-7. This embodiment proposes a robot arm transfer device for a CNC lathe, including a base 2, a robot 21, a track 5 and four cleaning boxes 6. A main swing arm 1 is installed on the top of the base 2, and an auxiliary swing arm 11 is installed on one end of the robot 21. Four circumferentially evenly distributed brackets 3 are welded on the outer circumference of the base 2. Two connecting plates 4 are fixedly connected to the bottom of the bracket 3 by screws. A driving shaft 8 is rotatably installed on the two connecting plates 4. A driving gear 15 and a wheel 17 are fixedly sleeved on the outer circumference of the driving shaft 8. Support plates 12 are welded on the bottom of the two connecting plates 4. A driven shaft 9 and a directional rod 10 are rotatably installed on the support plate 12. The outer circumference of the driven shaft 9 is fixedly sleeved with The driven gear 16, the driving gear 15 and the driven gear 16 are meshed, the outer peripheral surface of the directional rod 10 is fixedly sleeved with a cleaning brush 7, and the outer peripheral surfaces of the directional rod 10 and the driven shaft 9 are jointly fixedly sleeved with a synchronous belt 13. Through the arrangement of structures such as the cleaning brush 7 and the support plate 12, the wheel 17 moves while the cleaning brush 7 rotates through the synchronous belt 13, and the rolling cleaning brush 7 cleans the track 5, so that impurities such as dust and oil that fall on the track 5 are brushed away. The track 5 can clean the dust, oil and other impurities on the track surface in real time or regularly to ensure that the track 5 is clean and smooth, which can effectively reduce the friction and resistance of the robot arm during the transfer process and improve the accuracy and stability of the transfer.

[0030] See also Figure 1-6 Straight grooves 20 are provided on both sides of the track 5 , and the driven shaft 9 passes through the interior of the straight grooves 20 .

[0031] See also Figure 1-6 A sliding groove 19 is provided on one side of the track 5 , and the directional rod 10 passes through the interior of the sliding groove 19 .

[0032] See also Figure 1-6A synchronous wheel 14 is fixedly sleeved on the outer circumference of the directional rod 10 and the driven shaft 9 , and the synchronous belt 13 is installed together on the outer circumference of the two synchronous wheels 14 .

[0033] See also Figure 1-6 The support plate 12 is provided with a rotating hole, and the driven shaft 9 is rotatably installed inside the rotating hole.

[0034] See also Figure 1-6 A supporting hole is provided on the supporting plate 12, and the directional rod 10 is rotatably installed inside the supporting hole.

[0035] The specific implementation process of the utility model is as follows: the wheel 17 runs stably on the track 5, and the driving gear 15 on the driving shaft 8 also rotates continuously. The driving gear 15 and the driven gear 16 are meshed, thereby driving the driven gear 16 to rotate. The rotation of the driven gear 16 further drives the rotation of the driven shaft 9. Due to the setting of the synchronous belt 13, the directional rod 10 rotates with the rotation of the driven shaft 9, thereby driving the rotation of the cleaning brush 7. As the cleaning brush 7 rotates, it begins to clean the track 5 thoroughly and effectively. Due to the setting of the support plate 12, the cleaning brush 7 follows the wheel 17 for real-time cleaning while the wheel 17 moves.

[0036] Example 2

[0037] See also Figure 1-7 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that two dovetail grooves 22 are opened at one end of the track 5, and two fixing blocks 18 are welded inside the cleaning box 6. The fixing blocks 18 and the dovetail grooves 22 have the same shape. Through the arrangement of structures such as the dovetail grooves 22 and the cleaning box 6, which are located at one end of the track, impurities on the track can be easily collected to prevent impurities from scattering or re-attaching to the track 5. This can ensure that the track 5 is always kept in a clean state, providing a stable and reliable working environment for the transfer of the robot arm.

[0038] In this embodiment, the operator can slide and install the cleaning box 6 through the dovetail groove 22 and the fixing block 18. When the cleaning brush 7 runs to the top of the track 5, the cleaned impurities are swept from the track into the cleaning box 6, thereby achieving efficient collection of dust, oil and other impurities on the track 5.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
