DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] For example, see Figure 1-3, an adjustable CNC machining transmission device, including a control box 1, a turntable 2 is rotatably connected to the side of the control box 1, the turntable 2 is fixedly connected to a threaded rod 3 and the threaded rod 3 is rotatably connected to the control box 1, a sliding seat 4 is threadedly connected to the side of the threaded rod 3, a sliding rod 8 is fixedly connected to the inside of the control box 1, the sliding seat 4 is slidably connected to the sliding rod 8, brackets 5 are fixedly installed on both sides of the sliding seat 4, a clamping block 6 is fixedly installed on the opposite sides of the two brackets 5, and the clamping block 6 is slidably connected to a rotating wheel 7, a fixed plate 9 is fixedly installed inside the control box 1, the fixed plate 9 is rotatably connected to a transmission shaft 12, the transmission shaft 12 is slidably connected to the rotating wheel 7, the end of the transmission shaft 12 away from the turntable 2 is fixedly connected to a power shaft 121, the power shaft 121 passes through the control box 1 and is rotatably connected to the control box 1, a motor 10 is fixedly installed on the inner wall of the control box 1, and the output of the motor 10 A speed-changing roller 11 is fixedly installed on the shaft, and the side of the speed-changing roller 11 away from the motor 10 is rotatably connected to the fixed plate 9, and the speed-changing roller 11 contacts the side of the rotating wheel 7 but is not connected, and a plurality of raised blocks are fixedly installed on the side of the transmission shaft 12, and an opening consistent with the specifications of the transmission shaft 12 is opened in the center of the rotating wheel 7, and a groove consistent with the size and specifications of the block 6 is opened on the side of the rotating wheel 7, so that the rotating wheel 7 is limited by the position of the blocks 6 on both sides, and there will be no deviation in the route, and the transmission can be stable. The utility model can translate the sliding seat 4 in the direction away from the rotating disk 2 by rotating the turntable 2, and the rotation speed of the transmission shaft 12 and the power shaft 121 is changed through the cooperation of the bracket 5, the block 6 and the rotating wheel 7, so that the rotation speed of the power shaft 121 is adjusted according to the different requirements of the mechanical processing transmission, so that the speed regulation range is wider and the usage scenarios are more diverse.

[0023] When in use, the motor 10 is started, and the output shaft of the motor 10 drives the speed change roller 11 to rotate, thereby causing the rotating wheel 7 in contact with the side of the speed change roller 11 to rotate, and the rotating wheel 7 drives the transmission shaft 12 to rotate in the same direction and at the same speed, so that the power shaft 121 rotates. At this time, the power shaft 121 can provide the power required for transmission for different machines. When the speed of transmission required increases, the turntable 2 is rotated in the forward direction, so that the threaded rod 3 rotates, so that the sliding seat 4 is translated in the direction close to the turntable 2 under the action of the thread, and the sliding seat 4 is prevented from being driven to rotate by the threaded rod 3 under the restriction of the sliding rod 8, thereby ensuring that the direction of the sliding seat 4 is not The sliding seat 4 drives the bracket 5 and the block 6 to translate in the same direction. The block 6 is engaged in the side groove of the rotating wheel 7, driving the rotating wheel 7 to translate in the direction close to the turntable 2. At this time, the rotating wheel 7 is displaced to the widest part of the speed change roller 11. At this time, the circumference of the speed change roller 11 when it rotates one circle is the largest, so that the rotation speed of the rotating wheel 7 is the fastest. The speed of the power shaft 121 reaches the fastest through the cooperation with the transmission shaft 12. The reverse rotation of the turntable 2 can make the sliding seat 4 translate in the direction away from the turntable 2. Through the cooperation of the bracket 5, the block 6 and the rotating wheel 7, the rotation speed of the transmission shaft 12 and the power shaft 121 slows down.

[0024] For example 2, please refer to Figure 4-5 On the basis of the first embodiment, a liquid storage cylinder 18 is fixedly installed on the top of the control box 1, a slide rail 16 is fixedly installed on the inner wall of the control box 1, a linkage block 15 is slidably connected inside the slide rail 16, the linkage block 15 is fixedly connected to the sliding seat 4 through a linkage rod 19, a liquid infusion cylinder 14 is fixedly installed on the top of the linkage block 15, a sliding piston 25 is slidably connected to the inner wall of the liquid infusion cylinder 14, a drip port 17 is fixedly installed on the bottom of the liquid infusion cylinder 14, an airbag 13 is fixedly installed on one side of the inner wall of the control box 1 close to the sliding seat 4, the airbag 13 is connected to the top of the liquid infusion cylinder 14 through a connecting pipe, the side bottom of the liquid infusion cylinder 14 is connected to the liquid storage cylinder 18 through a connecting pipe, and the upper part of the liquid infusion cylinder 14 is pressurized by the airbag 13 , so that the sliding piston 25 moves downward and squeezes the lubricating liquid, so that the lubricating liquid drips downward through the dripping port 17, and the lubricating liquid is supplemented to the rotating wheel 7. The airbag 13 is made of rubber, and the tip part of the dripping port 17 is located directly above the rotating wheel 7. The side of the sliding seat 4 close to the airbag 13 is arranged in an arc structure, so that the airbag 13 will not be damaged during the contact process. The utility model cooperates with the airbag 13 and the liquid replenishing cylinder 14, so that the sliding piston 25 moves downward and squeezes the lubricating liquid, so that the lubricating liquid drips downward through the dripping port 17, and the dripping port 17 can always be directly above the rotating wheel 7, so as to supplement the lubricating liquid to the rotating wheel 7 and ensure the later maintenance of the equipment.

[0025] When in use, on the basis of Example 1, when the sliding seat 4 is translated left and right along the sliding rod 8, the linkage block 15 is driven to slide in the sliding rail 16 through the linkage rod 19, and the linkage block 15 is used to ensure that the drip port 17 is always kept directly above the rotating wheel 7. When the sliding seat 4 moves to the middle of the sliding rod 8, the sliding seat 4 will come into contact with the airbag 13 and gradually begin to squeeze the airbag 13. Under the action of pressure, the airbag 13 is deformed and the air inside enters the upper part of the inner wall of the fluid replenishing cylinder 14 through the connecting pipe, so that the sliding piston 25 slides downward under the upper pressure. At this time, due to the action of gravity, the lubricating fluid inside the liquid storage cylinder 18 enters the lower side of the sliding piston 25 on the inner wall of the fluid replenishing cylinder 14, but does not drip downward due to the influence of the surface tension of the liquid. As the sliding piston 25 moves downward and squeezes the lubricating fluid, the lubricating fluid drips downward through the drip port 17, replenishing the lubricating fluid to the rotating wheel 7, thereby ensuring the later maintenance of the equipment.

[0026] For example 3, please refer to Figure 6On the basis of the first embodiment, a groove 22 is provided on the side of the control box 1, and a protective shell 23 is fixedly installed on the side of the control box 1. A linkage rod 20 is slidably connected inside the groove 22. The linkage rod 20 is fixedly connected to the linkage block 15, and a pointer 21 is fixedly installed on the side of the linkage rod 20 away from the linkage block 15. Through the mutual cooperation between the linkage block 15 and the linkage rod 20, the pointer 21 makes a real-time indication of the position of the sliding seat 4. A scale 24 is printed on the side of the control box 1, and a transparent glass observation window is embedded on the side of the protective shell 23, which can facilitate the operator to observe and make corresponding adjustments to the equipment at any time. The utility model drives the linkage rod 20 to synchronously displace in the groove 22 through the linkage block 15 and the linkage rod 1 19 to keep synchronous displacement with the rotating wheel 7, so that the operator observes the position of the scale 24 indicated by the pointer 21, and can obtain the current speed of the power shaft 121, thereby better controlling the device.

[0027] When in use, on the basis of embodiment one, the linkage block 15 maintains synchronous displacement with the rotating wheel 7 through the drive of the linkage rod 19, thereby driving the linkage rod 20 to synchronously displace in the groove 22, and making the pointer 21 synchronously displace. The operator can obtain the current rotational speed of the power shaft 121 by observing the position of the indicator scale 24 indicated by the pointer 21, thereby better controlling the device.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
