Figure 3 This is a second cross-sectional view of the present invention. Figure 4 This is a three-dimensional structural diagram of the guide rod in this utility model. Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0016] As shown in the figure, an auxiliary support device for machining includes a support base 1 and a support rod 2 for providing auxiliary support. A guide rod 3 is detachably connected to the lower part of the support rod 2. The support base 1 is provided with a guide cavity 10 with an upper opening that cooperates with the guide rod 3. The guide rod 3 is movably disposed in the guide cavity 10. An elastic support element 4 is disposed in the guide cavity 10 and is supported below the guide rod 3. A locking mechanism is provided between the support base 1 and the guide rod 3 to lock the support position of the support rod 2.

[0017] In this specific embodiment, the lower part of the support rod 2 is a threaded connection part 21 with external threads, and the guide rod 3 is provided with a matching threaded hole 31. The support rod 2 and the guide rod 3 are detachably connected by the threaded connection part 21 being screwed into the threaded hole 31. The structure is simple, the connection is reliable, the cost is low, and the installation and disassembly are convenient and quick.

[0018] In this specific embodiment, a locking nut 5 is screwed onto the threaded connection 21. After being tightened, the locking nut 5 abuts against the upper end face of the guide rod 3. This effectively prevents the support rod 2 from loosening due to vibration during processing, ensuring the stability of the support height and the rigidity of the support.

[0019] In this specific embodiment, the locking mechanism includes a locking bolt 6. The side of the support base 1 has a locking screw hole 11 that mates with the locking bolt 6. The locking screw hole 11 is connected to the guide cavity 10. The side of the guide rod 3 has a matching locking recess 32. The locking bolt 6 is screwed into the locking screw hole 11. The width of the locking recess 32 in the vertical direction is greater than the inner diameter of the locking screw hole 11. The inner end of the locking bolt 6 abuts against the locking recess 32 to lock the support position of the support rod 2. The above design is a simple and reliable mechanical locking method. Through the cooperation of the locking bolt 6 and the recess, the guide rod 3 is firmly locked, eliminating the potential backlash problem caused by the elastic element, thereby effectively ensuring machining accuracy.

[0020] In this specific embodiment, the locking recess 32 has a side locking abutment surface 321 and a lower limiting surface 322. The side locking abutment surface 321 is an inclined end face that slopes inward from top to bottom. The central axis of the locking screw hole 11 is perpendicular to the side locking abutment surface 321, so that after locking, the end face of the inner end of the locking bolt 6 can fit against the side locking abutment surface 321. The aforementioned corresponding inclined surface fit causes the locking bolt 6 to generate a downward component force when tightened, pressing the guide rod 3 downward, achieving the effect of tightening as it is locked, greatly enhancing the reliability and rigidity of the lock. The lower limiting surface 322, in cooperation with the locking bolt 6, can also effectively prevent the guide rod 3 from coming off the support seat 1 when not tightened.

[0021] In this specific embodiment, the side of the support base 1 is provided with a plurality of locking screw holes 11 spaced apart along the axial direction. This provides multiple locking positions, allowing the selection of the most suitable locking point according to different support heights, increasing the flexibility and applicability of the device.

[0022] In this specific embodiment, an anti-rotation mechanism is provided between the support base 1 and the guide rod 3 to prevent the guide rod 3 from rotating within the guide cavity 10 after locking. This effectively prevents the guide rod 3 from rotating after locking, avoiding changes in support height or locking failure caused by rotation, and further ensuring the stability of the support.

[0023] In this specific embodiment, the anti-rotation mechanism includes an anti-rotation screw 7. The side of the support base 1 is provided with an anti-rotation screw hole 13 that mates with the anti-rotation screw 7. The anti-rotation screw hole 13 communicates with the guide cavity 10. The side of the guide rod 3 is provided with a matching anti-rotation locking recess 33. The anti-rotation screw 7 is screwed into the anti-rotation screw hole 13. The width of the anti-rotation locking recess 33 in the vertical direction is greater than the inner diameter of the anti-rotation screw hole 13. The inner end of the anti-rotation screw 7 abuts against the anti-rotation locking recess 33 to achieve anti-rotation locking. The structure is simple, and the rotation problem of the guide rod 3 is reliably solved through the cooperation of the anti-rotation screw 7 and the corresponding recess.

[0024] In this specific embodiment, the bottom of the guide cavity 10 is provided with a vertically penetrating connecting hole 101. A connecting bolt 8 is provided in the connecting hole 101. The head of the connecting bolt 8 is limited and positioned in the guide cavity 10. The rod of the connecting bolt 8 extends downward and is positioned outside the support base 1 for connecting to the corresponding tooling base plate to achieve the fixed installation of the support base 1 on the tooling base plate.

[0025] In this specific embodiment, the elastic support element 4 is a spring. Springs are standard components, have low operating costs, are easy to obtain and replace, and can provide stable and reliable elastic support force.
