Abstract
Description
Technical Field
[0001] This utility model relates to the field of saw shaft support frame technology, and in particular to a multi-blade saw shaft anti-bending support frame. Background Technology
[0002] A saw shaft is typically a cylindrical metal shaft, usually made of high-strength alloy steel. A multi-blade saw shaft has multiple mounting points for the saw blades, commonly connected to the saw blades via keyways to ensure the blades rotate with the shaft and transmit torque. Bearings are installed at both ends of the saw shaft to support its rotation and ensure its accuracy. Driven by a motor, the multi-blade saw shaft rotates at high speed, causing the multiple saw blades mounted on it to rotate and form a cutting plane. When materials such as wood are fed to the saw blades, the saw teeth cut the wood, separating it into multiple pieces. The saw shaft's rotational speed, along with parameters such as the saw blade's diameter and number of teeth, determines the cutting speed and accuracy. During use, the multi-blade saw shaft can bend due to its own weight or significant bending stress, affecting its subsequent use. Utility Model Content
[0003] To overcome the technical defects of the existing technology, this utility model provides a multi-blade saw shaft anti-bending support frame, which can effectively prevent the saw shaft from bending during use.
[0004] The technical solution adopted by this utility model is as follows: it includes two mounting plates, with support legs fixedly installed on the bottom surface of the two mounting plates, and a connecting plate fixedly connected between the two mounting plates. A sliding groove is fixedly opened on the upper surface of the mounting plates, and a sliding seat is slidably installed in the sliding groove. A lifting component is fixedly installed in the sliding seat. The sliding groove allows the sliding seat to slide horizontally, and the lifting component can flexibly adjust the installation position of the saw shaft. A connecting column is slidably installed on the upper end of the lifting component, and a saw shaft mounting seat is fixedly installed on the upper surface of the connecting column. The saw shaft mounting seat can be used to install the saw shaft.

[0009] Preferably, in order to fix the sliding seat to the mounting plate, the sliding seat is provided with fixing holes, which are symmetrically distributed on both sides of the sliding seat.
[0010] Preferably, in order to achieve a better fixing effect on the sliding seat, the limiting hole corresponds to the fixing hole, and the limiting hole and the fixing hole are connected through each other.
[0011] Preferably, in order to allow for better height adjustment of the saw shaft, the number of lifting components is two, and the two lifting components are symmetrically distributed on the upper surface of the two mounting plates.
[0012] The beneficial effects of this utility model are as follows: This utility model adopts a lifting component. When the weight of the saw shaft itself is large or small, the center of gravity of the saw shaft can be lowered or raised by adjusting the lifting height of the lifting rod, thereby avoiding the bending problem caused by the saw shaft due to its own weight.

[0019] The present invention will be further described below with reference to the accompanying drawings:
[0020] like Figures 1-5 As shown, this embodiment provides a multi-blade saw shaft anti-bending support frame, including two mounting plates 1. Support legs 2 are fixedly installed on the bottom of the two mounting plates 1. A connecting plate 3 is fixedly connected between the two mounting plates 1. A sliding groove 5 is fixedly opened on the upper surface of the mounting plate 1. A sliding seat 4 is slidably installed in the sliding groove 5. A lifting component 6 is fixedly installed in the sliding seat 4. A connecting column 7 is slidably installed on the upper end of the lifting component 6. A saw shaft mounting seat 8 is fixedly installed on the upper surface of the connecting column 7. During operation, the saw shaft is installed on the saw shaft mounting seat 8. The support legs 2 at the bottom of the mounting plate 1 firmly support the entire support frame, making it stable on the ground. By sliding the sliding seat 4 in the sliding groove 5 on the upper surface of the mounting plate 1, the lateral position of the saw shaft can be flexibly adjusted to adapt to different processing requirements. At the same time, with the operation of the lifting component 6 in the sliding seat 4, the connecting column 7 can be driven to slide up and down, accurately adjusting the height of the saw shaft mounting seat 8 and the saw shaft, preventing the saw shaft from bending due to its own weight.
[0021] As a technical optimization solution of this utility model, specifically as follows: Figure 2 and Figure 3As shown, the lifting assembly 6 includes a lifting cylinder 601, a lifting rod 602 slidably installed inside the lifting cylinder 601, multiple equidistant through holes 603 fixedly opened on both sides of the inner wall of the lifting cylinder 601, mounting grooves 604 fixedly opened on both sides near the lower end of the lifting rod 602, a limit spring 605 fixedly installed in the mounting groove 604, a limit block 606 fixedly connected to one end of the limit spring 605, a buffer groove 607 fixedly opened on the upper surface of the lifting rod 602, the lifting cylinder 601 fixedly installed on the sliding seat 4, the mounting groove 604 communicating with the through holes 603, the limit block 606 slidably engaging in the through hole 603 and the mounting groove 604, a buffer spring 10 fixedly installed in the buffer groove 607, one end of the buffer spring 10 fixedly connected to the lower surface of the connecting column 7, the connecting column 7 slidably installed inside the buffer groove 607, and the operator... The limiting blocks 606 on both sides of the lifting rod 602 can be manually pressed. Since the limiting blocks 606 are connected to the limiting springs 605, when pressed, the limiting springs 605 contract, and the limiting blocks 606 retract from the current through hole 603 into the mounting groove 604. At this time, the lifting rod 602 can slide freely in the lifting cylinder 601. The lifting rod 602 can be moved up or down to a suitable height so that the through hole 603 and the mounting groove 604 are aligned. The limiting springs 605 restore their deformation and push the limiting blocks 606 to re-engage into the through hole 603 and the mounting groove 604 to achieve height fixation, thereby achieving the effect of adjusting the center of gravity of the saw shaft. The connecting column 7 is slidably installed in the buffer groove 607 and connected to one end of the buffer spring 10. The vibration energy is transmitted to the buffer spring 10, which absorbs and buffers the vibration through extension and contraction deformation, reducing the impact on the saw shaft and reducing the risk of the saw shaft bending due to vibration.
[0022] As a technical optimization solution of this utility model, specifically as follows: Figure 4 and Figure 5 As shown, limit holes 9 are provided on the upper surfaces of both mounting plates 1. The limit holes 9 are located on both sides of the sliding groove 5 on the mounting plate 1. The limit holes 9 are arranged in an array on the upper surface of the mounting plate 1. Fixing holes 11 are fixedly provided on the sliding seat 4. The fixing holes 11 are symmetrically distributed on both sides of the sliding seat 4. The limit holes 9 correspond to the fixing holes 11 and are connected through each other. When the sliding seat 4 is pushed to slide along the sliding groove 5 on the mounting plate 1 to the appropriate position, the fixing holes 11 on both sides of the sliding seat 4 will be aligned and connected through the corresponding limit holes 9 on the mounting plate 1. Then, a limit pin or bolt or other fastener is inserted to make the fixing holes 11 and the limit holes 9 tightly connected, thereby locking the sliding seat 4 securely and ensuring that the saw shaft is accurately and stably positioned during processing, avoiding deviation and shaking.
[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 1As shown, there are two lifting components 6, and the two lifting components 6 are symmetrically distributed on the upper surface of the two mounting plates 1. In multi-blade sawing, the two symmetrically distributed lifting components 6 work together to balance the force on both ends of the saw shaft and avoid uneven force on both ends of the saw shaft.
