Description

Technical Field

[0001] This utility model relates to the field of transmission component technology, specifically transmission components for precision equipment. Background Technology

[0002] Transmission refers to the transfer of power between machines, or the transmission of mechanical power to end equipment through an intermediate medium. This type of transmission includes chain drive, friction drive, hydraulic drive, gear drive, and belt drive, etc. Equipment needs to use transmission components to transmit power during operation.

[0003] A search revealed a prefabricated drive shaft (publication number CN217873852U). The technical solution includes a connecting plate and a drive rod. A through hole is formed at the center of the connecting plate's surface. A damping rubber sleeve is installed within the through hole, and a tie rod is installed within the damping rubber sleeve. This facilitates the disassembly and replacement of the universal joint fork, making operation convenient, efficient, and practical. However, the connection between the connecting rod and the drive rod is only secured by two positioning pins, resulting in poor installation stability. During transmission, play is prone to occur, and prolonged use due to vibration and wear will lead to increasingly larger play, thereby reducing the accuracy of equipment operation.

[0004] Based on this, we now offer precision equipment transmission components that can eliminate the drawbacks of existing devices. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-4 As shown, the transmission component of the precision equipment includes a buffer mechanism 1, both ends of the buffer mechanism 1 are provided with universal joints 2, and one end of each universal joint 2 is fixedly installed with an mounting sleeve 3;

[0027] The inner wall of the mounting sleeve 3 is provided with a second limiting groove 4 at equal intervals in a ring. A second limiting block 5 is slidably installed inside the second limiting groove 4. A connecting rod 6 is fixedly installed outside the second limiting block 5. A first fixing mechanism 7 is provided at equal intervals in a ring on the outside of the mounting sleeve 3.

[0028] In this embodiment, the first fixing mechanism 7 facilitates the fixing of the connecting rod 6 and the mounting sleeve 3. The cooperation between the second limiting block 5 and the second limiting groove 4 effectively positions the connecting rod 6 and the mounting sleeve 3 during installation, preventing the misalignment of the first positioning hole 8 and the first pin 702 from causing the angle of the connecting rod 6 to be adjusted by rotation. This greatly improves the installation efficiency and stability. The transmission components will vibrate during use. The buffer mechanism 1 can buffer the vibration, improving the stability and service life of the transmission components.

[0029] In one embodiment, such as Figure 1 and Figure 2 As shown, the first fixing mechanism 7 includes a first fixing sleeve 701, which is equidistantly and annularly fixedly installed on the outside of the mounting sleeve 3. A first pin 702 is slidably installed inside the first fixing sleeve 701. A first end cap 703 is installed on one end of the first fixing sleeve 701. One end of the first pin 702 passes through the first end cap 703 and is fixedly installed with a first handle 704. A first fixing ring 705 is fixedly installed on the outside of the first pin 702, and the first fixing ring 705 is located inside the first fixing sleeve 701. A first spring 706 is sleeved on the outside of the first pin 702, and the first spring 706 is positioned... When it is necessary to install the connecting rod 6 and the mounting sleeve 3 between the first fixing ring 705 and the first end cap 703, hold the first handle 704 and pull the first pin 702 outward. During this process, the first spring 706 is compressed, and the first pin 702 is completely inserted into the interior of the first fixing sleeve 701. Then, slide the connecting rod 6 into the interior of the mounting sleeve 3 and slowly loosen the first handle 704. Due to the reset action of the first spring 706, the first pin 702 moves into the interior of the mounting sleeve 3. One end of the first pin 702 is inserted into the interior of the connecting rod 6 through the first positioning hole 8, thereby fixing the connecting rod 6 and the mounting sleeve 3. This structure is simple and convenient for installation and disassembly.

[0030] In one embodiment, such as Figure 3As shown, the buffer mechanism 1 includes a telescopic sleeve 101 and a sliding rod 104. One end of the telescopic sleeve 101 and one end of the sliding rod 104 are fixedly installed with two universal joints 2. The inner wall of the telescopic sleeve 101 is provided with a first limiting groove 102 at equal intervals. A first limiting block 103 is slidably installed inside the first limiting groove 102. The first limiting block 103 is fixedly connected to the sliding rod 104. The other end of the sliding rod 104 is provided with a sealing ring 105, and the sealing ring 105 is located inside the telescopic sleeve 101. The outer side of the telescopic sleeve 101 is provided with an air hole 106. The cooperation between 101 and slide rod 104 allows the distance between the two universal joints 2 to be changed, making it easy to adjust according to actual usage. The cooperation between the first limiting groove 102 and the first limiting block 103 effectively prevents slide rod 104 from rotating inside telescopic sleeve 101, improving the stability of the installation of slide rod 104 and telescopic sleeve 101. When vibration occurs, slide rod 104 slides back and forth inside telescopic sleeve 101. Due to the setting of sealing ring 105, the air inside telescopic sleeve 101 can only enter or exit through air hole 106, thereby playing a buffering role and improving stability.

[0031] In one embodiment, such as Figure 2 As shown, a first positioning hole 8 is provided on the outside of the connecting rod 6 at the position corresponding to the first pin 702. The first pin 702 is adapted to the first positioning hole 8. The connecting rod 6 and the mounting sleeve 3 can be easily fixed by the cooperation of the first positioning hole 8 and the first pin 702.

[0032] In one embodiment, such as Figure 1 and Figure 4 As shown, a key rod 9 is fixedly connected to one end of the connecting rod 6. A gear 10 is slidably installed on the outside of the key rod 9. A keyway 11 adapted to the key rod 9 is provided on the outside side of the gear 10. The cooperation between the key rod 9 and the keyway 11 improves the stability of the installation of the gear 10 and the connecting rod 6.

[0033] In one embodiment, such as Figure 1 and Figure 4 As shown, the gear 10 is provided with a second fixing mechanism 12 on its exterior, which is used to fix the gear 10 to the key rod 9.

[0034] In one embodiment, such as Figure 4As shown, the second fixing mechanism 12 includes a second fixing sleeve 1201, which is fixedly installed on the outside of the gear 10. A second pin 1202 is slidably installed inside the second fixing sleeve 1201. A second end cap 1203 is installed on one end of the second fixing sleeve 1201. One end of the second pin 1202 passes through the second end cap 1203 and is fixedly installed with a second handle 1204. A second fixing ring 1205 is fixedly installed on the outside of the second pin 1202, and the second fixing ring 1205 is located inside the second fixing sleeve 1201. A second spring 1206 is sleeved on the outside of the second pin 1202. 06 is located between the second fixing ring 1205 and the second end cap 1203. When it is necessary to install the key rod 9 and the gear 10, hold the second handle 1204 and pull the second pin 1202 outward. During this process, the second spring 1206 is compressed, and the second pin 1202 is completely inserted into the interior of the second fixing sleeve 1201. Then, slide the key rod 9 into the interior of the gear 10 and slowly loosen the second handle 1204. Due to the reset action of the second spring 1206, the second pin 1202 moves into the interior of the keyway 11. One end of the second pin 1202 is inserted into the interior of the key rod 9 through the second positioning hole 13, thereby fixing the key rod 9 and the gear 10. This structure is simple and convenient for installation and disassembly.

[0035] In one embodiment, such as Figure 4 As shown, a second positioning hole 13 is provided on the outside of the key rod 9 at the position corresponding to the second pin 1202. The second pin 1202 is adapted to the key rod 9. The key rod 9 and the gear 10 are easily fixed by the cooperation between the second positioning hole 13 and the second pin 1202.

[0036] The above embodiments disclose a transmission component for precision equipment. When installing the connecting rod 6 to the mounting sleeve 3, the first handle 704 is held to pull the first pin 702 outwards. During this process, the first spring 706 is compressed, and the first pin 702 fully enters the interior of the first fixing sleeve 701. Then, the connecting rod 6 is slidably inserted into the interior of the mounting sleeve 3. The first handle 704 is slowly loosened. Due to the restoring action of the first spring 706, the first pin 702 moves into the interior of the mounting sleeve 3. One end of the first pin 702 is inserted into the interior of the connecting rod 6 through the first positioning hole 8, thereby fixing the connecting rod 6 to the mounting sleeve 3. The key rod 9 and gear 10... The installation principle is similar and will not be repeated here. The distance between the two universal joints 2 can be changed through the cooperation between the telescopic sleeve 101 and the slide rod 104, which is convenient to adjust according to the actual use. The cooperation between the first limiting groove 102 and the first limiting block 103 effectively prevents the slide rod 104 from rotating inside the telescopic sleeve 101, and improves the stability of the installation of the slide rod 104 and the telescopic sleeve 101. When vibration occurs, the slide rod 104 slides back and forth inside the telescopic sleeve 101. Due to the setting of the sealing ring 105, the air inside the telescopic sleeve 101 can only enter or exit through the air hole 106, thereby playing a buffering role.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
