Abstract
Description
Technical Field

[0002] In modern manufacturing, precision machining technology is key to improving product quality and production efficiency. This is especially true in the machining of thin rods, where extremely high demands are placed on the flexibility and precision of machining equipment. Traditional thin rod machining equipment typically employs single-axis or fixed clamping methods, which limits the versatility and adaptability of machining processes. These limitations become particularly pronounced when dealing with workpieces with complex shapes or high slenderness ratios.
[0003] In existing technologies, some processing equipment attempts to improve processing flexibility by adding robotic arms or multi-axis linkages, but these solutions often come with a significant increase in cost and operational complexity. For example, some equipment achieves multi-angle processing by installing rotatable fixtures on the worktable, but this design is still difficult to control precisely when processing thin rods and is difficult to adapt to thin rods of different diameters.
[0004] In addition, existing thin rod processing equipment often cannot maintain processing accuracy when performing long-distance processing due to the limitations of the equipment structure, or requires frequent adjustments to the equipment settings to adapt to thin rods of different diameters. This not only reduces processing efficiency but also increases the difficulty of operation. Utility Model Content

[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0044] This embodiment relates to a sliding type tooling for machining thin rods. In terms of overall structure, as follows... Figure 1 As shown, it includes a base 1, a chuck 2, and a multi-stage sliding mechanism.
[0045] The chuck 2 and the multi-stage sliding mechanism are respectively arranged and installed on the base 1. The thin rod is installed on the chuck 2 and extends to the multi-stage sliding mechanism. The thin rod processing mechanism 5 is installed on the multi-stage sliding mechanism. The thin rod processing mechanism 5 processes the thin rod. The multi-stage sliding mechanism includes a first-stage sliding part 3 that slides back and forth along the central axis of the thin rod and a second-stage sliding part 4 that slides perpendicular to the central axis. The thin rod processing mechanism 5 is installed on the second-stage sliding part 4.
[0046] It is worth mentioning that the thin rod passes through the chuck 2 and extends from the chuck 2 to the thin rod processing mechanism 5. The thin rod is clamped by the chuck 2 and can also rotate with the chuck 2. The multi-stage sliding mechanism can accurately control the position of the thin rod processing mechanism 5, thereby improving the processing accuracy. The first-stage sliding part 3 can drive the thin rod processing mechanism 5 to slide along the length of the thin rod, thereby increasing the processing distance of the thin rod. The second-stage sliding part 4 can adjust the distance between the thin rod processing mechanism and the lead screw 3032 to ensure that thin rods of different thicknesses can be processed.
[0047] Based on the above overall introduction, this embodiment presents an exemplary structure of a sliding thin rod machining fixture, such as... Figure 2 As shown, the primary sliding part 3 includes a fixed seat 301 mounted on the base 1, a sliding seat 302 that moves on the fixed seat 301, and a first driving member 303 that drives the sliding seat 302 to move. The secondary sliding part 4 moves along with the sliding seat 302. It should be noted that the secondary sliding part 4 is mounted on the sliding seat 302, and the first driving member 303 is fixedly mounted on the fixed seat 301. The first driving member 303 can drive the sliding seat 302 to slide, and the sliding seat 302 drives the thin rod processing mechanism 5 to process the thin rod in the length direction.
[0048] As a preferred option, such as Figure 3 As shown, the first driving component 303 in this embodiment includes a threaded sleeve 3031 mounted on a sliding seat 302, a lead screw 3032 that drives the threaded sleeve 3031 to move, and a first motor 3033 that drives the lead screw 3032 to rotate. The lead screw 3032 is rotatably connected to a fixed seat 301. Specifically, both ends of the lead screw 3032 are rotatably connected to the fixed seat 301 through bearings. The driving end of the first motor 3033 and the lead screw 3032 are connected through a coupling. The first motor 3033 drives the lead screw 3032 to rotate. The lead screw 3032 and the threaded sleeve 3031 are screwed together. When the lead screw 3032 rotates, it can drive the sliding seat 302 to move.
[0049] As a preferred option, it remains as follows Figure 3As shown, in this embodiment, the fixed base 301 is provided with a track 3034 to assist the movement of the sliding base 302, and a slider 3035 adapted to the track 3034 is fixedly provided on the sliding base 302. There are at least two sets of tracks 3034 and sliders 3035. Specifically, the purpose of providing two sets of tracks 3034 and sliders 3035 is to ensure the stability of the sliding base 302 when it moves. When the lead screw 3032 drives the sliding base 302 to move, the slider 3035 moves on the track 3034. The arrangement of tracks 3034 and sliders 3035 ensures the smooth sliding of the sliding base 302 on the fixed base 301 and avoids friction or jamming.
[0050] As a preferred option, such as Figure 3 As shown, the sliding seat 302 in this embodiment is L-shaped, with two tracks 3034 respectively installed on the top and side surfaces of the fixed seat 301, and a slider 3035 disposed on the sliding seat 302 at a position corresponding to the tracks 3034. Specifically, since the secondary sliding part 4 is installed on the sliding seat 302 and moves on the sliding seat 302, the sliding seat 302 is subjected to a large force. The two ends of the L-shaped sliding seat 302 can be connected to the fixed seat 301 through the tracks 3034 and the slider 3035, thereby improving the stability of the sliding seat 302 during sliding.
[0051] As a preferred implementation method, such as Figure 4 As shown, in this embodiment, the secondary sliding part 4 includes a movable platform 401 slidably disposed on a sliding seat 302, and a second driving member 402 disposed between the movable platform 401 and the sliding seat 302. The first driving member 303 has the same structure as the second driving member 402. It should be noted that the slider 3035 and the screw sleeve 3031 of the second driving member 402 are mounted on the sliding seat 302. The first motor 3033, the lead screw 3032, and the track 3034 of the second driving member 402 are mounted on the bottom of the movable platform 401. The driving of the second driving member 402 ensures that the movable platform 401 moves on the sliding seat 302, which facilitates the thin rod processing mechanism 5 to approach the thin rod.
[0052] As a preferred implementation method, such as Figure 5 As shown, in this embodiment, the thin rod processing mechanism 5 includes a processing part 501 for processing thin rods, a bracket 502 for mounting the processing part 501, a second motor 503 for driving the processing part 501 to rotate, and a hydraulic cylinder 504 for driving the processing part 501 to extend and retract. A circular sleeve 505 is rotatably mounted on the bracket 502. The processing part 501 and the circular sleeve 505 are engaged. The hydraulic cylinder 504 pushes the processing part 501 to slide within the circular sleeve 505.
[0053] It should be noted that at least two machining parts 501 can be set, and the machining part 501 can be selected according to the machining situation. For example, it can be used to install milling cutters, welding guns, or drill bits. Drill bits can be installed in the circular sleeve 505, and the snap-fit method can be a slot and block method. The piston rod of the hydraulic cylinder 504 abuts against the drill bit, that is, the hydraulic cylinder 504 can push the drill bit to extend and retract. The second motor 503 and the circular sleeve 505 are respectively equipped with pulleys 506. The circular sleeve 505 can be rotated by the belt drive. This setting ensures that when drilling is required, the drill bit can be extended out of the circular sleeve 505 for drilling. Of course, when installing milling cutters, the second motor 503 can be turned off, and only the hydraulic cylinder 504 can be turned on to drive the milling cutter to extend and retract. The welding gun can be directly installed on the bracket 502 for convenient machining of thin rods.
[0054] The sliding rod machining fixture in this embodiment improves the flexibility and adaptability of rod machining through the design of a multi-stage sliding mechanism, enabling it to meet the machining needs of rods of different lengths and diameters. Precise control of the movement of the sliding seat 302 improves the accuracy and efficiency of rod machining. The provision of at least two sets of tracks 3034 and sliders 3035 enhances the stability and accuracy of the sliding seat 302's movement, reducing friction and jamming during movement. The L-shaped sliding seat 302 design improves its stability and accuracy under heavy loads.
[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
