[0027] Please refer to Figs. 1-3 The utility model provides a new technical scheme: a spindle aluminium sleeve clamp, including support frame 1, be provided with aluminium sleeve fixed subassembly on support frame 1, and aluminium sleeve fixed subassembly is used for stabilizing and fixing aluminium sleeve, and aluminium sleeve fixed subassembly includes rotating disc 2, V-shaped block 5, tooth 6, fixed column 7, fixed disc 8, knob 11 and nut seat 16.

[0028] Two fixing discs 8 in the aluminum sleeve fixing assembly are fixedly connected on the two inner side walls of the support frame 1, and two arc-shaped sliding grooves 9 are formed in the fixing discs 8;

[0029] The arc-shaped sliding grooves 9 on the two fixing discs 8 are oppositely arranged, the upper ends of the two rotating discs 2 are fixedly connected with arc-shaped fixing plates 10, and the two rotating discs 2 are located between the arc-shaped fixing plates 10 and the horizontal plate of the support frame 1.

[0030] Further, the outer surfaces of the rotating discs 2 are slidingly connected with the arc-shaped fixing plates 10 and the horizontal plate of the support frame 1, the opposite sides of the two rotating discs 2 are provided with a plurality of sliding grooves 3, and the sliding grooves 3 are slidingly connected with sliding rails 4.

[0031] Further, the V-shaped blocks 5 are fixedly connected between the corresponding two sliding rails 4, a plurality of teeth 6 are fixedly connected in the V-shaped surface of the V-shaped block 5, and the teeth 6 are used to increase the friction.

[0032] Further, the fixed columns 7 are fixedly connected to the outer surfaces of the corresponding V-shaped blocks 5, the fixed columns 7 extend into the inner walls of the corresponding arc-shaped sliding grooves 9, and the arc-shaped fixing plates 10 are fixedly connected with two fixing bases 14.

[0033] Further, the two fixing bases 14 are rotatably connected with bidirectional screw rods 15, the knobs 11 are fixedly sleeved on the middle ends of the bidirectional screw rods 15, and the opposite sides of the two rotating discs 2 are fixedly connected with sliding groove rails 13.

[0034] Further, two nut bases 16 are threadedly sleeved on the outer surfaces of the two ends of the bidirectional screw rods 15, the nut bases 16 are fixedly connected with moving sliding columns 12, and the corresponding plurality of moving sliding columns 12 are slidingly connected with the inner walls of the corresponding sliding groove rails 13.

[0035] Further, when in use, the aluminum sleeve of the spindle to be processed is placed between the V-shaped surfaces of the two V-shaped blocks 5, and then the knob 11 is manually rotated. The knob 11 drives the two nut seats 16 to move close to each other through the bidirectional screw 15. At this time, the nut seat 16 drives the sliding groove rail 13 and the rotating disc 2 thereon to rotate through the moving slide column 12. When the rotating disc 2 rotates between the horizontal plate of the support frame 1 and the arc-shaped fixed plate 10, it can drive the V-shaped blocks 5 thereon to rotate simultaneously. The V-shaped blocks 5 can drive the plurality of V-shaped blocks 5 to move to the center position of the rotating disc 2 through the cooperation of the fixed columns 7 thereon and the inner walls of the arc-shaped sliding grooves 9, so that the teeth 6 on the corresponding two groups of V-shaped blocks 5 can fix the aluminum sleeve. At this time, since the arc-shaped sliding grooves 9 on the two fixed discs 8 are oppositely arranged, when the two groups of sliding rails 4 are gradually tightened inward, they can also apply two counteracting torsional forces to the aluminum sleeve. This can make the fixation of the aluminum sleeve not rely on single clamping force. The clamping and fixation of this torsional force can make the aluminum sleeve be clamped more stably, avoiding the problem that in the traditional clamp, the aluminum sleeve is often clamped only by single clamping force, which easily leads to deformation of the relatively weak aluminum sleeve under uneven stress, thereby affecting the production precision.

[0036] Further, through the cooperation of the bidirectional screw 15, the nut seat 16, the moving slide column 12, the sliding groove rail 13 and the rotating disc 2 and other components, the rotation and centripetal movement of the V-shaped blocks 5 and the aluminum sleeve placed therebetween are realized, thereby providing multi-directional clamping force, improving the stability of clamping, avoiding the instability of clamping caused by single acting force in the traditional way, and making the aluminum sleeve prone to shaking or displacement during the machining process, further affecting the production quality.

[0037] Working principle: the aluminum sleeve of the spindle to be processed is placed between the V-shaped surfaces of the two V-shaped blocks 5, and then the knob 11 is manually rotated. The knob 11 drives the two nut seats 16 to move close to each other through the bidirectional screw 15. At this time, the nut seat 16 drives the sliding groove rail 13 and the rotating disc 2 thereon to rotate through the moving slide column 12. When the rotating disc 2 rotates between the horizontal plate of the support frame 1 and the arc-shaped fixed plate 10, it can drive the V-shaped blocks 5 thereon to rotate simultaneously. The V-shaped blocks 5 can drive the plurality of V-shaped blocks 5 to move to the center position of the rotating disc 2 through the cooperation of the fixed columns 7 thereon and the inner walls of the arc-shaped sliding grooves 9, so that the teeth 6 on the corresponding two groups of V-shaped blocks 5 can fix the aluminum sleeve. At this time, since the arc-shaped sliding grooves 9 on the two fixed discs 8 are oppositely arranged, when the two groups of sliding rails 4 are gradually tightened inward, they can also apply two counteracting torsional forces to the aluminum sleeve. This can make the fixation of the aluminum sleeve not rely on single clamping force. The clamping and fixation of this torsional force can make the aluminum sleeve be clamped more stably.

[0038] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
