Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to an auxiliary support component for long workpieces. Background Technology

[0002] In the field of machining, long shaft workpieces (such as slender shafts and lead screws) are susceptible to bending and cylindricity errors during machining due to their large length-to-diameter ratio and poor rigidity. When the length is long, the workpiece may sag due to its own weight and vibrate due to centrifugal force during turning or grinding, and may even develop bamboo-shaped or drum-shaped defects, which seriously affect the machining accuracy.

[0003] Traditional auxiliary support devices mostly use fixed center frames or tool holders to offset radial forces through single or limited support points. However, such structures have limitations such as unadjustable support positions, fixed support point spacing, and large friction with the workpiece, making it difficult to adapt to the diverse processing needs of workpieces with different diameters. Therefore, we propose an auxiliary support component for long workpieces to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and to propose an auxiliary support component for long workpieces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Two support plates are fixedly installed on the top of the fixed platform. Sliding openings are provided on the outer side walls of the support plates. The outer side walls of the long shaft workpiece and the inner side walls of the two sliding openings are slidably connected. A support mechanism is provided on the long shaft workpiece.

[0007] The support mechanism includes multiple fixed frames fixedly installed on the inner sidewall of the tile-shaped limiting block. The inner sidewall of the fixed frame is rotatably connected to a movable wheel. The two tile-shaped limiting blocks are detachably connected by multiple bolt pairs and sleeved on the long shaft workpiece. A threaded rod is fixedly connected between the two support plates. A limiting plate is fixedly installed at the bottom of the lower tile-shaped limiting block. A sliding hole is opened on the outer sidewall of the limiting plate. The outer sidewall of the threaded rod and the inner sidewall of the sliding hole are slidably connected. Two limiting nuts are threadedly sleeved on the outer sidewall of the threaded rod.

[0008] Preferably, the distance between two adjacent fixed frames is the same.

[0009] Preferably, the inner sidewall of the fixed frame is rotatably connected to a rotating shaft, and the movable wheel is fixedly sleeved on the outer sidewall of the rotating shaft.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A long workpiece auxiliary support assembly includes a fixed platform 1, a long shaft workpiece 2, and two tile-shaped limiting blocks 3. Two support plates 4 are fixedly installed on the top of the fixed platform 1. Sliding holes 5 are opened on the outer side walls of the support plates 4. The outer side walls of the long shaft workpiece 2 and the inner side walls of the two sliding holes 5 are slidably connected. A support mechanism is provided on the long shaft workpiece 2. The support mechanism includes multiple fixed frames 6 fixedly installed on the inner side walls of the tile-shaped limiting blocks 3. Moving wheels 7 are rotatably connected to the inner side walls of the fixed frames 6. The two tile-shaped limiting blocks 3 are detachably connected to each other by multiple bolt pairs 8 and sleeved on the long shaft workpiece 2. A threaded rod 9 is fixedly connected between the two support plates 4. A limiting plate 10 is fixedly installed at the bottom of the lower tile-shaped limiting block 3. A sliding hole 11 is opened on the outer side wall of the limiting plate 10. The outer side wall of the threaded rod 9 and the inner side wall of the sliding hole 11 are slidably connected. Two limiting nuts 12 are threadedly sleeved on the outer side wall of the threaded rod 9.

[0022] To further explain, the tile-shaped limiting block 3 in the support mechanism is detachably connected to the long shaft workpiece 2 via bolt pair 8. It can be adjusted and fixed according to the diameter of the long shaft workpiece 2, providing stable support. The limiting plate 10 is slidably connected to the threaded rod 9. With the help of the limiting nut 12, the position of the tile-shaped limiting block 3 on the threaded rod 9 can be adjusted. This facilitates the support of the tile-shaped limiting block 3 on different positions of the long shaft workpiece 2, while also serving as a limiting function to prevent the tile-shaped limiting block 3 from moving arbitrarily.

[0023] Reduce friction: The movable wheel 7 inside the fixed frame 6 can reduce the friction between the long shaft workpiece 2 and the limiting block, making it easier for the long shaft workpiece 2 to rotate or move during processing and improving the smoothness of processing.

[0024] like Figure 2 As shown, the distance between two adjacent fixed frames 6 is the same.

[0025] To further explain, this design makes the supporting force on the long shaft workpiece 2 more uniform, avoiding deformation or shaking caused by uneven force on the long shaft workpiece 2 due to inconsistent spacing of support points, and further improving the stability and reliability of the support.

[0026] like Figure 2 As shown, a rotating shaft is rotatably connected to the inner side wall of the fixed frame 6, and the movable wheel 7 is fixedly sleeved on the outer side wall of the rotating shaft.

[0027] To further explain, this design makes the rotation of the movable wheel 7 more flexible and smooth, reduces resistance and wear during rotation, extends the service life of the movable wheel 7 and the entire support assembly, and can also better adapt to the movement of the long-shaft workpiece 2.

[0028] like Figure 1 and Figure 3As shown, a limiting mechanism is provided on the top of the tile-shaped limiting block 3. The limiting mechanism includes a threaded hole opened on the top of the tile-shaped limiting block 3. A limiting bolt 13 is threadedly connected to the inner wall of the threaded hole. An arc-shaped limiting friction block 14 is fixedly installed at the end of the limiting bolt 13 near the long shaft workpiece 2.

[0029] To further explain, this design can further limit the long shaft workpiece 2, preventing axial or radial displacement during processing and improving processing accuracy.

[0030] like Figure 2 As shown, an arc-shaped handle 15 is fixedly installed at the end of the limiting bolt 13, which is far from the long axis workpiece 2.

[0031] To further explain, the arc-shaped handle 15 allows operators to easily rotate the limiting bolt 13, making it convenient to adjust the position of the arc-shaped limiting friction block 14 and improving the ease of operation.

[0032] like Figure 1 and Figure 3 As shown, a limit nut 16 is threaded onto the outer wall of the limit bolt 13.

[0033] To further explain, the limit nut 16 can lock the limit bolt 13 to prevent the limit bolt 13 from loosening due to vibration or other reasons during the processing, thus ensuring the stability and reliability of the limit mechanism.

[0034] like Figure 1 and Figure 2 As shown, the outer wall of the limiting plate 10 is provided with an installation port 17 to facilitate the movement of the limiting bolt 13 located below.

[0035] To further explain, this design facilitates the movement of the lower limiting bolt 13, making the adjustment of the limiting mechanism more flexible, while also avoiding interference between the limiting bolt 13 and the limiting plate 10, ensuring the normal operation of the entire support assembly.

[0036] The functional principle of this utility model can be explained through the following operation methods:

[0037] Install tile-type limit block 3

[0038] Place two tile-shaped limiting blocks 3 on both sides of the long shaft workpiece 2, so that the movable wheel 7 in the fixed frame 6 contacts the outer wall of the long shaft workpiece 2. Use bolt pair 8 to connect the two tile-shaped limiting blocks 3. Tighten the bolt pair 8 to make the tile-shaped limiting blocks 3 tightly fitted on the long shaft workpiece 2. During the tightening process, it is necessary to ensure that the tile-shaped limiting blocks 3 are firmly installed and that the movable wheel 7 can rotate freely.

[0039] Adjust the position of tile-shaped limit block 3

[0040] Hold the long shaft workpiece 2 with both hands and slide its outer side wall along the sliding opening 5 on the outer side wall of the support plate 4. Move the long shaft workpiece 2 to the approximate position where support is needed. Operate the limiting plate 10 at the bottom of the tile-shaped limiting block 3 located below, so that the sliding hole 11 of the limiting plate 10 is aligned with the threaded rod 9 between the two support plates 4. Then, put the limiting plate 10 on the threaded rod 9.

[0041] Loosen the two limiting nuts 12 fitted on the threaded rod 9, and move the limiting plate 10 up and down along the threaded rod 9, thereby moving the tile-shaped limiting block 3 to a suitable height position to meet the support requirements of the long shaft workpiece 2. After adjusting the position, tighten the two limiting nuts 12 respectively so that they are tightly pressed against the limiting plate 10 to prevent the tile-shaped limiting block 3 from moving arbitrarily during the processing.

[0042] Adjusting the limit mechanism

[0043] Hold the arc-shaped handle 15 and rotate the limiting bolt 13. Since the limiting bolt 13 is threadedly connected to the threaded hole at the top of the tile-shaped limiting block 3, when rotating, the limiting bolt 13 will bring the arc-shaped limiting friction block 14 closer to the long shaft workpiece 2. Continue to rotate the arc-shaped handle 15 until the arc-shaped limiting friction block 14 gently adheres to the outer wall of the long shaft workpiece 2, thus initially limiting the long shaft workpiece 2.

[0044] Tighten the limiting nut 16 on the outer wall of the rotating limiting bolt 13 so that the limiting nut 16 presses tightly against the top of the tile-shaped limiting block 3 to prevent the limiting bolt 13 from loosening due to vibration or other reasons during processing.

[0045] Operations and adjustments during processing

[0046] When the long shaft workpiece 2 is being processed, if the long shaft workpiece 2 needs to rotate or move, the moving wheel 7 in the fixed frame 6 will rotate accordingly to reduce the friction between the long shaft workpiece 2 and the limiting block, ensuring smooth processing. During the processing, the position and status of the long shaft workpiece 2 should be observed at any time. If the long shaft workpiece 2 is found to have a slight displacement, the arc handle 15 can be gripped again and the limiting bolt 13 can be finely adjusted so that the arc limiting friction block 14 further fits the long shaft workpiece 2, enhancing the limiting effect.

[0047] If it is necessary to adjust the support position of the tile-type limiting block 3 on the long shaft workpiece 2, the displacement limiting nut 12 can be loosened first, and the position of the tile-type limiting block 3 on the threaded rod 9 can be readjusted according to the above steps of "adjusting the position of the tile-type limiting block 3". After the adjustment is completed, the displacement limiting nut 12 can be tightened again.

[0048] Disassembly and storage

[0049] After processing, first loosen the limiting nut 16 on the outer wall of the limiting bolt 13, then hold the arc handle 15 and rotate the limiting bolt 13 in the opposite direction to move the arc-shaped limiting friction block 14 away from the long shaft workpiece 2. Loosen the bolt pair 8 connecting the two tile-shaped limiting blocks 3, remove the two tile-shaped limiting blocks 3 from the long shaft workpiece 2, loosen the limiting nut 12, remove the limiting plate 10 from the threaded rod 9, clean all parts, and store them properly for future use.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
