DETAILED DESCRIPTION

[0019] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: a single-axis tapping chuck for sheet metal, comprising a fixed seat 1, the inner cavity of the fixed seat 1 being conical. A through hole is provided on the right side of the fixed seat 1. A sleeve 4 is slidably installed inside the through hole. A first spring 5 is fixedly connected between the sleeve 4 and the left side of the inner cavity of the fixed seat 1. A fixed disk 15 is fixedly connected to the left side of the sleeve 4. The inner side of the fixed disk 15 extends to the inside of the sleeve 4. The outer side of the fixed disk 15 extends to the outside of the sleeve 4. Four grooves 8 are evenly and annularly provided on the inner wall of the fixed disk 15.

[0021] The inside of the grooves 8 are all provided with clamping components.

[0022] The clamping assembly includes a fixed plate 13, which is slidably mounted within the groove 8. A third spring 12 is fixedly connected to the interior of the groove 8 on one side of the fixed plate 13, corresponding to the interior of the sleeve 4. The movable plate 6 is affixed to the fixed plate 13. The third spring 12 is sleeved around the outside of the movable plate 6.

[0023] A connecting block 16 is fixed to one end of the movable plate 6. This block 16 fits snugly within the inner cavity of the fixed base 1. Because the inner cavity of the fixed base 1 is tapered, as the sleeve 4 moves into the interior of the fixed base 1, the axial diameter of the inner cavity of the fixed base 1 that the connecting block 16 contacts becomes increasingly smaller, causing the movable plate 6 to move into the interior of the sleeve 4.

[0024] The other end of the movable plate 6 is fixed with a clamping plate 7. The clamping plate 7 is located inside the sleeve 4.

[0025] It should be noted that the movable plate 6 is slidably connected to both the inner and outer sides of the fixed plate 15 .

[0026] An annular groove is formed on the right end of the outer surface of the fixing base 1. A rotating plate 2 is slidably mounted in the annular groove. Four rectangular grooves 10 are formed inside the right end of the fixing base 1 at positions corresponding to the annular groove. Each of the rectangular grooves 10 contains a stopper assembly for fixing the sleeve 4.

[0027] The limiter assembly includes a clamping block 11. The clamping block 11 is slidably mounted within the rectangular groove 10. A second spring 9 is fixedly connected between the top of the clamping block 11 and the interior of the rectangular groove 10. Four sets of clamping slots 3 are formed along the outer surface of the sleeve 4 in the axial direction. These four sets of clamping slots 3 correspond to the four clamping blocks 11. Each of the bottom ends of the rectangular groove 10 has a through hole. The bottom end of the clamping block 11 engages with the corresponding clamping slot 3 through the through hole.

[0028] A connecting hole is provided between the rectangular groove 10 and the annular groove. A soft rope 14 is fixedly connected to the top of the block 11. The soft rope 14 passes through the connecting hole and is fixedly connected to the rotating plate 2.

[0029] Working principle:

[0030] During use, the rotating plate 2 rotates about the axis of the fixed base 1, which moves the flexible cord 14. The flexible cord 14 then moves the clamping block 11 along the rectangular slot 10, releasing the clamping block 11 from the clamping slot 3 to facilitate subsequent operation. Simultaneously, the clamping block 11 compresses the second spring 9, which exerts a force to restore the clamping block 11 to its original state.

[0031] Place the tap between the clamps 7, and the tap pushes the sleeve 4 to move into the fixed seat 1. The sleeve 4 compresses the first spring 5 so that the first spring 5 has the force to restore the sleeve 4 to its original state;

[0032] The sleeve 4 moves the movable plate 6. Since the inner cavity of the fixed seat 1 is conical, when the movable plate 6 moves to the left, the connecting block 16 is squeezed toward the inside of the sleeve 4 by the inner cavity of the fixed seat 1. Then, the movable plate 6 drives the fixed plate 13 to move toward the inside of the sleeve 4. The fixed plate 13 compresses the third spring 12 so that the third spring 12 has the force to restore the movable plate 6 to its original state. At the same time, the movable plate 6 moves the clamping plates 7 toward each other to clamp the tap and prevent the tap from moving and affecting subsequent operations.

[0033] After the tap is clamped by the clamping plate 7, the rotating plate 2 is released, so that the extension of the second spring 9 causes the clamping block 11 to move along the rectangular groove 10 toward the sleeve 4, so that the clamping block 11 enters the corresponding clamping groove 3 to maintain the clamping state of the fixed seat 1 on the tap.

[0034] When the tap needs to be replaced or removed, the rotating plate 2 rotates around the axis of the fixed base 1, which moves the flexible rope 14. The flexible rope 14 moves the clamping block 11 along the rectangular groove 10 to release the clamping block 11 and the clamping groove 3. This causes the first spring 5 to extend and return to its original state, thereby pushing the sleeve 4 out of the fixed base 1. In turn, the movable plate 6 drives the clamping plate 7 away from each other, and the tap is removed. This makes the installation and removal of the tap more convenient and improves work efficiency.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
