DETAILED DESCRIPTION
[0021] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0022] like Figures 1 to 2 As shown, a clamping device is provided on a first workpiece 1 and a second workpiece 2 , and includes a clamping assembly 3 .
[0023] The first workpiece 1 and the second workpiece 2 are in a pipe structure, and the ends of the first workpiece 1 and the second workpiece 2 are both conical structures. The first workpiece 1 is a fan outlet pipe, and the second workpiece 2 is an exhaust pipe. Since the fan outlet pipe and the exhaust pipe are of different sizes, when the clamping assembly 3 clamps the first workpiece 1 and the second workpiece 2, the fan outlet pipe and the exhaust pipe are better matched, thereby increasing the application range of the clamping device. The second workpiece 2 is arranged on the right side of the first workpiece 1, and a wedge-shaped positioning portion 4 is provided on the front and rear sides of the left end of the second workpiece 2. The existence of the wedge-shaped positioning portion 4 facilitates the use and positioning of the clamping assembly 3. A rectangular long groove 5 is provided in the middle of the wedge-shaped positioning portion 4, which runs through the left and right sides.
[0024] The outer surface of the clamping assembly 3 is provided with an anti-skid layer, and the provision of the anti-skid layer increases friction and further improves the clamping effect of the clamping assembly. The clamping assembly 3 is clamped to the right end of the first workpiece 1, and the clamping assembly 3 includes a first clamping unit 6 and a second clamping unit 7 with the same structure and symmetrical arrangement, and the second clamping unit 7 is arranged behind the first clamping unit 6. The first clamping unit 6 and the second clamping unit 7 both include a vertical rod 8, and the width dimension between the vertical rods 8 of the first clamping unit 6 and the second clamping unit 7 is equal to the diameter dimension of the right end of the first workpiece 1 where it is clamped, so that it is convenient for the two vertical rods 8 to clamp the first workpiece 1, further improving the scope of application. The upper and lower ends of the vertical rod 8 are both provided with screw through holes 9. The first screw 12 passes through the screw through hole 9 at the upper end of the vertical rod 8 of the first clamping unit 6 and the screw through hole 9 at the upper end of the vertical rod 8 of the second clamping unit 7 in sequence and is fixed by a first butterfly nut 13. The second screw 14 passes through the screw through hole 9 at the lower end of the vertical rod 8 of the first clamping unit 6 and the screw through hole 9 at the lower end of the vertical rod 8 of the second clamping unit 7 in sequence and is fixed by a second butterfly nut 15. The diameter of the screw through hole 9 is equal to the diameter of the first screw 12 and is equal to the diameter of the second screw 14. Finally, the first screw 12 and the second screw 14 clamp the right end of the first workpiece 1.
[0025] The front surface of the vertical rod 8 of the first clamping unit 6 and the rear surface of the vertical rod of the second clamping unit 7 are both provided with wedge-shaped positioning blocks 10, which are also convenient for the use and positioning of the clamping assembly 3. The middle part of the wedge-shaped positioning block 10 is provided with an open groove 11 that passes through the left and right sides corresponding to the rectangular long groove 5. The third screw 17 with the third butterfly nut 16 passes through the rectangular long groove 5 of the wedge-shaped positioning part 4 on the front side of the left end of the second workpiece 2 and the open groove 11 of the wedge-shaped positioning block 10 on the front surface of the first clamping unit 6 in sequence and is fixed by the nut 18. The third screw 17 can slide forward and backward along the rectangular long groove 5 and the open groove 11, so that the appropriate position can be selected for clamping according to the actual model and size of the first workpiece 1 and the second workpiece 2, and the application range is wider. The fourth screw 20 with the fourth butterfly nut 19 passes through the rectangular long groove 5 of the wedge-shaped positioning part 4 on the rear side of the left end of the second workpiece 2 and the open groove 11 of the wedge-shaped positioning block 10 on the rear surface of the second clamping unit 7 in sequence and is fixed by the nut 18. The fourth screw 20 can slide forward and backward along the rectangular long groove 5 and the open groove 11. In this way, the first workpiece 1 and the second workpiece 2 can also be clamped in a suitable position according to the actual model and size of the first workpiece 1 and the second workpiece 2, and the application range is wider. The height dimension of the rectangular long groove 5 is equal to the height dimension of the open groove 11, which is equal to the diameter dimension of the third screw 17 and the diameter dimension of the fourth screw 20. After tightening the nut 18, the first workpiece 1 and the second workpiece 2 are clamped by the clamping assembly 3.
