[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Figures 1-8 The present invention is described in detail with reference to the embodiments.

[0028] A disc-type clamping device for furniture manufacturing includes a support platform 1. The support platform 1 has grooves 2 at both ends. The upper end is used to clamp round wood, and the lower end is used to clamp square wood. When in use, which end is placed on top for clamping is selected according to needs.

[0029] A connecting column 3 is provided at the center of the support platform 1, a cavity 6 is provided inside the connecting column 3, a partition 13 is provided inside the cavity 6, a motor 14 is provided on the bottom wall of the partition 13 through a mounting frame, a conical gear disc 7 is provided for rotation inside the cavity 6, and the conical gear disc 7 is provided on the output end of the motor 14.

[0030] When used to clamp round timber, it can be adjusted according to the diameter of the round timber. During adjustment, the motor 14 is started to drive the conical toothed disc 7 to rotate, thereby driving the four conical gears 9 to rotate synchronously.

[0031] Four slide grooves 4 are vertically symmetrically arranged on the bottom wall of the groove 2. A reciprocating screw rod 5 is rotatably arranged in each of the four slide grooves 4. The reciprocating screw rod 5 is rotatably arranged between the side wall of the slide groove 4 and the outer side wall of the connecting column 3. The outer end of the reciprocating screw rod 5 inside one of the grooves 2 passes through the side wall of the slide groove 4 and is fixed with a knob 8. The inner end of the reciprocating screw rod 5 inside the other groove 2 passes through the side wall of the connecting column 3 and is fixed with a bevel gear 9. The four bevel gears 9 are all engaged with the bevel gear disc 7.

[0032] The four bevel gears 9 rotate synchronously, driving the four reciprocating screws 5 to rotate synchronously. Since the outer wall of the reciprocating screw 5 is slidingly provided with a clamping member 10, the four clamping members 10 can synchronously approach or move away from the round wood to be adaptively adjusted according to its diameter.

[0033] The clamping member 10 includes a fixed block 11, the bottom end of the fixed block 11 is slidably set on the threaded periphery of the reciprocating screw rod 5, and the upper end thereof is symmetrically provided with an accommodating groove 15 on both sides. A pressure block 12 is movably provided on the fixed block 11, and a pull ring 20 is provided on the top wall of the pressure block 12. The pressure block 12 can be pulled up by the pull ring 20. A moving rod 17 is symmetrically provided on the bottom wall of the pressure block 12, which can enable the moving rod 17 to move up and down inside the accommodating groove 15. A small groove 18 is provided at the bottom end of the moving rod 17, and an elastic member 16 is fixedly provided on the side wall of the small groove 18 and the bottom wall of the accommodating groove 15. The other end of the elastic member 16 is respectively fixed with a movable block 19 and a moving rod 17.

[0034] When the elastic member 16 in the small groove 18 is in a normal state, the movable block 19 is placed inside the adjustment cavity 21, which can prevent the moving rod 17 from moving up and down and clamping the wood. When the elastic member 16 in the accommodating groove 15 is in a normal state, the bottom wall of the pressing block 12 and the top wall of the fixed block 11 are in contact with each other, and the wood is not clamped at this time.

[0035] Several adjustment cavities 21 are provided on the side walls of the accommodating groove 15, and limiting grooves 23 are provided on both side walls of the adjustment cavity 21. An adjustment rod 22 is slidingly provided inside the adjustment cavity 21. The adjustment rod 22 can slide left and right under the restriction of the limiting groove 23, and a handle 24 is fixed on the outer end of the adjustment rod 22.

[0036] According to the thickness of the wood, the moving rod 17 can be selected to cooperate with different adjusting cavities 21. When one of the adjusting cavities 21 is suitable, pull the handle 24 to drive the adjusting rod 22 to move outward until it stops under the restriction of the limit groove 23. The adjusting rod 22 inside the other adjusting cavities 21 is placed at the other end of the limit groove 23, so that the inner wall of the adjusting rod 22 and the inner wall of the adjusting cavity 21 are in the same vertical plane. At this time, move the moving rod 17. When the movable block 19 reaches the selected adjusting cavity 21, it enters the adjusting cavity 21 under the rebound action of the elastic member 16, and organizes the moving rod 17 to continue moving, thereby clamping the wood.

[0037] A supporting block 25 is also fixedly provided on the side of the fixed block 11 facing the connecting column 3. The top of the supporting block 25 is on the same horizontal plane as the top of the connecting column 3. The top wall of the supporting block 25, the bottom wall of the pressing block 12 and the side wall of the fixed block 11 are all fixedly provided with a buffer layer 26. The buffer layer 26 is made of rubber. The top wall of the supporting block 25, the bottom wall of the pressing block 12 and the side wall of the fixed block 11 have a clamping and tightening effect on the wood.

[0038] On the clamping piece 10 at one end of the bevel gear 9, the opposite side walls of the buffer layer 26 arranged on the side wall of the fixing block 11 are all arc-shaped surfaces, which can better fit with the side wall of the round wood and better clamp and tighten it, while the opposite side walls of the buffer layer 26 on the clamping piece 10 at the other end are all flat surfaces, which can better fit with the side wall of the square wood and better clamp and tighten the square wood.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
