Description

Technical Field

[0001] This utility model relates to the field of CNC rotary table equipment technology, specifically a CNC rotary table for arc surface cam grinding. Background Technology

[0002] A CNC rotary table is a rotating device controlled by a computer program. It is mainly used in CNC machine tools and can achieve high-precision and high-efficiency rotary machining. It is usually composed of a rotary table spindle, servo motor, control system, etc., and can realize functions such as rotation, positioning, and machining.

[0003] A curved cam is a type of cam with an arc-shaped surface, widely used in various automated equipment and precision machinery. Therefore, it is generally processed using a special CNC rotary table for curved cam grinding. Traditional CNC rotary tables generally require multiple transmission mechanisms to rotate the curved cam material in multiple directions, which not only results in high operating costs but also poor ease of operation. Furthermore, the curved cam material also requires a special clamping structure for locking before processing, usually using bolts for direct fixation, which is inconvenient for disassembly and assembly. The tight clamping also causes vibration during rotation, which can easily wear down the surface of the curved cam material, reducing its performance.

[0004] To address these issues, we propose a CNC rotary table for arc-shaped cam grinding. Utility Model Content

Detailed Implementation

[0028] 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 specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0029] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0030] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a CNC rotary table for arc-shaped cam grinding.

[0031] Example 1:

[0032] Combination Figures 1-3 As shown, this utility model provides a CNC rotary table for arc-shaped cam grinding.

[0033] Specifically, the system includes a turntable 1, a support chassis 2, an arc-shaped cam element 3, and a drive mechanism 8. Two sets of mounting sleeves 4 are symmetrically installed on the left and right sides of the turntable 1. Each mounting sleeve 4 has a clamping suction cup 5 near the side of the arc-shaped cam element 3. The output end of the drive mechanism 8 is located at the bottom of the turntable 1 and is connected to a snap-fit ​​rotating plate 9. The top of the snap-fit ​​rotating plate 9 is located inside the turntable 1 and is connected to a transmission gear plate 10. Two sets of push-pull gear plates 16 are symmetrically and cross-meshing on both sides of the transmission gear plate 10. The inner bottom ends of both sets of mounting sleeves 4 are rotatably mounted with push-pull gears. One end of plate 16 is engaged with a driven gear 11, and the top of the driven gear 11 is connected to a first threaded rod 12. The outer side of the first threaded rod 12 is threaded with a lifting gear plate 13. The inner top of the two sets of mounting sleeves 4 are rotatably mounted with micro gears 14 that mesh with one side of the top of the lifting gear plate 13. One end of the micro gear 14 is connected to one end of the clamping suction cup 5. The extended side of the bottom end of the lifting gear plate 13 is slidably engaged with the inner side of the mounting sleeve 4. The engaging plate 9 and the bottom end face of the turntable 1 are engaged with each other. The top surface of the turntable 1 has symmetrical through-holes on both sides. Two sets of limiting through holes 15 are provided, and two sets of limiting slide grooves 17 are symmetrically provided on both sides of the inner bottom end of the turntable disk 1. The middle side and bottom end of the two sets of mounting sleeves 4 are respectively slidably engaged with the inner sides of the two sets of limiting through holes 15 and the two sets of limiting slide grooves 17. The limiting through holes 15 and the limiting slide grooves 17 both play a role in limiting and stabilizing the movement of the mounting sleeves 4. The bottom side of the mounting sleeves 4 is provided with movable openings 18 through both sides of the driven gear 11. The movable openings 18 are mainly for facilitating the lateral through movement of the two sets of push-pull toothed plates 16. One end of the two sets of push-pull toothed plates 16 slides through the movable openings 18. On the inner side, the middle extension ends of the two sets of push-pull toothed plates 16 are slidably engaged with the inner side of the two sets of limiting slide grooves 17. The use of the above components causes the rotating plate 9 to rotate, which in turn causes the turntable 1 to rotate as a whole. This causes the transmission toothed plate 10 to rotate, while also engaging and driving the two sets of push-pull toothed plates 16 to move laterally. It also engages and drives the driven gear 11 to rotate the first threaded rod 12, causing the lifting toothed plate 13 to move up and down. This causes the micro gear 14 to engage and rotate, causing the arc-shaped cam element 3 between the clamping suction cups 5 to rotate continuously, achieving a multi-faceted rotation control effect, improving ease of operation and reducing operating costs.

[0034] Example 2:

[0035] Combination Figure 2 and Figure 3 As shown, based on Example 1,

[0036] Specifically, one end of the clamping suction cup 5 is connected to a compression pad 24 that fits against both sides of the arc-shaped cam component 3. The elastic protective function of the compression pad 24 can reduce the wear force between the clamping suction cup 5 and the arc-shaped cam component 3. One end of the bottom outer side of each of the two sets of mounting sleeves 4 is connected to a push-pull support column 22. Two sets of adjusting locking rods 7 are symmetrically arranged on both sides of the bottom of the turntable 1. Two sets of locking holes 23 are symmetrically opened on both sides of the bottom of the turntable 1. One end of each of the two sets of adjusting locking rods 7 is connected to a snap-fit ​​sleeve 19 near the two sets of locking holes 23. The inner side of the push-pull support column 22 is threaded with a second threaded rod 20. One end of the second threaded rod 20 extends through the turntable 1. The locking hole 23 is slidably engaged with the inner side of the snap-fit ​​rotating plate 9. The outer side of the second threaded rod 20 is fitted with a compression spring 21 that is close to one end of the push-pull support column 22. The use of the above components and the components in Embodiment 1, by adjusting the locking rod 7 and the snap-fit ​​sleeve 19 to rotate the second threaded rod 20, causes the push-pull support column 22 to undergo transverse thread transmission, pushing the installation sleeve column 4 to move, so that the clamping suction cup 5 at the top end clamps and adsorbs the arc-shaped cam component 3. Finally, the snap-fit ​​sleeve 19 is embedded into the locking hole 23 and locked to complete the fixation. The elastic damping effect of the compression spring 21 fitted on the outer side of the second threaded rod 20 reduces the vibration force and improves the convenience of clamping and disassembly.

[0037] Combination Figure 2 As shown, in the above embodiments,

[0038] Specifically, a mounting support plate 6 is installed at the bottom of the support chassis 2. The mounting support plate 6 is mainly used to facilitate the overall installation and fixation of the CNC rotary table in the designated position. The drive mechanism 8 is installed in the middle of the interior of the support chassis 2. The drive mechanism 8 is a bidirectional drive mechanism that can continuously drive back and forth.

[0039] The working principle and usage process of this utility model are as follows: First, before adjusting the rotation, the locking sleeve 19 is pulled out from the locking hole 23 by adjusting the locking rod 7, and the second threaded rod 20 is rotated, causing the push-pull support column 22 to undergo lateral thread transmission and push the connected mounting sleeve column 4 to move, so that the clamping suction cup 5 and the compression pad 24 at the top clamp and adsorb the arc-shaped cam component 3. Finally, the locking sleeve 19 is inserted into the locking hole 23 and locked. After the fixation is completed, the elastic shock absorption effect of the compression spring 21 sleeved on the outside of the second threaded rod 20 reduces the vibration force, improves the convenience of clamping and disassembly, and improves the use effect. Secondly, during use, after completing the above fixation... Then, through the operation of the drive mechanism 8, the clamping plate 9 rotates, causing the turntable 1 to rotate as a whole. This causes the transmission gear plate 10 to rotate, which in turn drives the two sets of push-pull gear plates 16 with symmetrical meshing transmission to move laterally along the limiting slide groove 17 and move between the movable openings 18. The meshing drives the driven gear 11 to drive the first threaded rod 12 to rotate, causing the lifting gear plate 13 to slide up and down along the inner side of the mounting sleeve column 4 through threaded transmission, and causing the micro gear 14 to mesh and rotate. In this way, the clamping suction cup 5 drives the arc-shaped cam element 3 to rotate continuously. This multi-faceted rotating structure with integrated transmission improves the convenience of operation and saves operating costs.
