[0044] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0045] First, combine Figures 1 to 5 A split quick-change sleeve according to an embodiment of the present invention is described, which is used for rapid pairing and replacement of tightening tools and accessories, and has a wide range of application scenarios.

[0046] like Figures 1 to 5 As shown, the split quick-change sleeve of the embodiment of the present invention comprises: a tool sleeve 1, an accessory sleeve 2, a quick locking mechanism 3 and a loosening mechanism 4.

[0047] Specifically, if Figures 1 to 5As shown, in this embodiment, the tool barrel 1 is connected to the tightening tool, the output shaft of the tightening tool is inserted into the tool barrel 1, and the top end of the tool barrel 1 is connected to the tightening tool;

[0048] Accessories are installed in the accessory tube 2, such as insulating sleeves, screwdriver sleeves, etc.

[0049] The quick lock mechanism 3 is provided on the tool barrel 1 and the accessory barrel 2. The quick lock mechanism 3 locks and fixes the tool barrel 1 and the accessory barrel 2, and can quickly connect and lock the tool barrel 1 and the accessory barrel 2 in a short time, greatly shortening the operation preparation time.

[0050] The release mechanism 4 cooperates with the quick lock mechanism 3 so that the tool holder 1 and the accessory holder 2 can be quickly released when needed, making replacement or adjustment convenient.

[0051] Specifically, if Figures 1 to 5 As shown, in this embodiment, the quick lock mechanism 3 includes: a base 31, a slide 32, a push assembly, a plurality of locking beads 33, a plurality of locking holes 34 and a locking groove 35;

[0052] The base 31 is fixed on the outer wall of the accessory cylinder 2. The base 31 is used to support the slide cylinder 32 and provide a bottom limit for the slide cylinder 32.

[0053] The slide tube 32 is slidably mounted on the outer wall of the accessory tube 2 and is disposed on the base 31;

[0054] A plurality of locking holes 34 are arranged around the wall of the accessory cylinder 2, and a locking groove 35 is arranged around the outer peripheral wall of the tool cylinder 1. The locking groove 35 is an annular groove, and the plurality of locking holes 34 and the locking groove 35 cooperate with each other.

[0055] The locking beads 33 are movably arranged in the locking holes 34. A plurality of locking beads 33 correspond to a plurality of locking holes 34 one by one. The locking beads 33 are steel balls. When the locking beads 33 are engaged in the locking grooves 35, the tool barrel 1 and the accessory barrel 2 can be locked.

[0056] The pushing assembly is sleeved on the outer wall of the accessory tube 2 and is arranged between the slide tube 32 and the accessory tube 2;

[0057] The pushing assembly pushes the slide 32 downward to push the locking bead 33 to be locked in the locking groove 35, thereby locking the tool cylinder 1 and the accessory cylinder 2;

[0058] The release mechanism 4 cooperates with the slide 32 to drive the slide 32 upward, releasing the locking bead 33 in the locking groove 35, thereby achieving the release of the tool cylinder 1 and the accessory cylinder 2;

[0059] The overall structure is simple and exquisite, compact and stable, occupies little space and has strong durability.

[0060] Further, if Figures 1 to 5As shown, in this embodiment, the pushing assembly includes: a spring 36 and a retaining ring 37;

[0061] The retaining ring 37 is fixedly connected to the slide cylinder 32, and the retaining ring 37 can be integrally formed with the slide cylinder 32;

[0062] The spring 36 is sleeved on the outer wall of the accessory tube 2, and the two ends of the spring 36 are respectively in contact with the retaining ring 37 and the accessory tube 2. The spring 36 is arranged above the retaining ring 37, and the spring 36 drives the retaining ring 37 to abut the locking bead 33 in the locking hole 34. The elastic force of the spring 36 and the gravity of the slide cylinder 32 itself make the retaining ring 37 and the locking bead 33 in the locking hole 34 in a normal state; when the tool tube 1 and the accessory tube 2 are connected, the spring 36 will push the retaining ring 37 downward, so that the retaining ring 37 abuts the locking bead 33 in the locking hole 34, and the locking bead 33 is partially engaged in the locking groove 35, thereby realizing the locking of the tool tube 1 and the accessory tube 2. When the loosening mechanism 4 drives the slide cylinder 32 to move upward, it will push the retaining ring 37 upward to compress the spring 36, so that the locking bead 33 is in a free state, thereby realizing the loosening of the tool tube 1 and the accessory tube 2.

[0063] Further, if Figures 1 to 5 As shown, in this embodiment, the slide cylinder 32 includes a cylindrical cylinder 321 and a frustum cylinder 322;

[0064] The frustum tube 322 and the cylindrical tube 321 are integrally formed to enhance stability;

[0065] The bottom end of the conical tube 322 is connected to the base 31, and the top end of the conical tube 322 is connected to the cylindrical tube 321. The outer diameter of the bottom end of the conical tube 322 is smaller than the outer diameter of the top end of the conical tube 322, that is, the bottom of the conical tube 322 is inwardly contracted, which facilitates the insertion of the loosening mechanism 4 between the conical tube 322 and the base 31 to lift the slide tube 32.

[0066] Further, if Figures 1 to 5 As shown, in this embodiment, the base 31 has a first end and a second end relative to each other, the first end is connected to the slide 32, and the outer diameter of the base 31 gradually increases from the first end to the second end, that is, the top of the base 31 is inwardly retracted, which facilitates the insertion of the loosening mechanism 4 between the conical cylinder 322 and the base 31 to lift the slide 32.

[0067] Specifically, if Figures 1 to 5 As shown, in this embodiment, the release mechanism 4 includes: a fixing frame 41 and a U-shaped frame 42;

[0068] The U-shaped frame 42 is fixed on the fixed frame 41. The U-shaped frame 42 is inserted between the base 31 and the slide 32 to drive the slide 32 to move upward.

[0069] The opening of the U-shaped frame 42 is adapted to the accessory tube 2 , and the side of the U-shaped frame 42 away from the opening is arc-shaped, which can well adapt to the shape of the accessory tube 2 .

[0070] Further, if Figures 1 to 5 As shown, in this embodiment, the U-shaped frame 42 includes a base 421 and two arms 422;

[0071] The base 421 is fixed on the fixing frame 41, and the two supporting arms 422 are relatively fixed at the two ends of the base 421. The two supporting arms 422 are inserted between the base 31 and the slide 32 to support the slide 32, so that the slide 32 moves upward, compressing the spring 36, so that the locking bead 33 is in a free state, and the tool cylinder 1 is pulled out vertically to separate and replace the accessory cylinder 2;

[0072] A raised surface 423 is vertically provided on the inner side of the support arm 422. The raised surface 423 has a certain raised height h in the vertical direction, so that the retaining ring 37 can completely leave the locking bead 33, ensuring the free state of the locking bead 33.

[0073] The distance between the two support arms 422 gradually decreases from the top surface to the raised surface 423 and gradually increases from the raised surface 423 to the bottom surface. That is, both the upper and lower sides of the raised surface 423 are slopes 424 facing the raised surface 423, which facilitates the insertion of the support arms 422 between the slide 32 and the base 31.

[0074] The raised surface 423 is in a right-angled trapezoid, and the side of the raised surface 423 close to the base 421 is a right-angled side, that is, the raised height h of the raised surface 423 is smaller than the side close to the base 421 on the side away from the base 421. Since the U-shaped frame 42 not only realizes the loosening of the tool barrel 1 and the accessory barrel 2, but also realizes the matching connection between the tool barrel 1 and the accessory barrel 2, when the tool barrel 1 is to be connected to the corresponding accessory barrel 2, the tightening tool will drive the tool barrel 1 to move to the U-shaped frame 42 where the corresponding accessory barrel 2 is placed, and the tool barrel 1 is inserted downward into the accessory barrel 2, and then The tightening tool brings the tool barrel 1 and the accessory barrel 2 out of the U-shaped frame 42 toward the opening. As the lifting height h of the lifting surface 423 of the support arm 422 gradually decreases, the lifting force of the support arm 422 on the slide 32 gradually weakens until it disappears. After the accessory barrel 2 is completely separated from the U-shaped frame 42, the spring 36 extends to drive the retaining ring 37 to reset. During the reset process, the retaining ring 37 on the slide 32 will gradually contact and squeeze the locking bead 33 in the lock hole 34, so that the locking bead 33 can be completely embedded in the lock groove 35 of the tool barrel 1 and be completely fixed.

[0075] Further, if Figures 1 to 5 As shown, in this embodiment, the release mechanism 4 further includes: a first detection sensor 43 and a second detection sensor 44;

[0076] The first detection sensor 43 and the second detection sensor 44 are fixed on the fixing frame 41;

[0077] The first detection sensor 43 is opposite to the tool cylinder 1 and detects the presence of the tool cylinder 1. When the tool cylinder 1 performs the task of replacing the accessory cylinder, the current task execution position can be quickly confirmed through the sensors 43 and 44.

[0078] The second detection sensor 44 is opposite to the accessory tube 2 and detects the presence or absence of the accessory tube 2;

[0079] Through the signals of the first detection sensor 43 and the second detection sensor 44 , the external control system can automatically call the corresponding assembly application.

[0080] Further, if Figures 1 to 5 As shown, in this embodiment, a square column 11 is provided at the bottom of the tool barrel 1, and a square hole 21 is provided in the accessory barrel 2, and the square hole 21 is adapted to the square column 11 to realize torque transmission; an adapter square head is provided at the bottom of the accessory barrel 2, which can be compatible with standard specifications on the market, and is convenient for users to flexibly select the required application sleeve, and is convenient for users to quickly replace multiple sleeves with a single tool in a flexible, single-station multi-sleeve assembly scenario; an adapter square hole is provided at the top of the tool barrel 1 to match the tool square head of standard specifications on the market, and an O-ring is provided in the adapter square hole to reduce rotational deflection.

[0081] Working principle: When the tool barrel 1 needs to be replaced with the accessory barrel 2, the tightening tool drives the tool barrel 1 to move to the open side of the U-shaped frame 42 that is not equipped with the accessory barrel 2. The accessory barrel 2 moves along with the tool barrel 1 toward the base 421 of the U-shaped frame 42 and enters the U-shaped frame 42. The support arm 422 of the U-shaped frame 42 lifts the slide barrel 32 and the retaining ring 37 of the accessory barrel 2. The retaining ring 37 loosens the locking bead 33, making the locking bead 33 free. The tool barrel 1 is then pulled up vertically to be separated from the accessory barrel 2 and replaced.

[0082] The tool cylinder 1 is moved to the top of the accessory cylinder 2 that needs to be locked, and the accessory cylinder 2 is inserted vertically downward and into place. The tool cylinder 1 and the accessory cylinder 2 are moved out of the U-shaped frame 42 as a whole. The supporting force of the arm 422 of the U-shaped frame 42 on the slide cylinder 32 is gradually weakened to disappear. After the accessory cylinder 2 is completely separated from the U-shaped frame 42, the spring 36 and the retaining ring 37 are completely reset. During the reset process, the retaining ring 37 will gradually contact and squeeze the locking bead 33 in the accessory cylinder 2, so that the locking bead 33 of the accessory cylinder 2 can be completely embedded in the locking groove 35 of the tool cylinder 1 and be completely fixed.

[0083] Above, refer to Figures 1 to 5The present invention describes a split quick-change sleeve according to an embodiment of the present invention, which has the advantages of quick replacement and locking, compact and stable structure, strong durability, wide adaptability and simple operation, which significantly improves work efficiency; the tool barrel and accessory barrel can be quickly paired and replaced through a quick locking and loosening mechanism, and the specifications are automatically identified by a detection sensor, and the torque transmission is reliable; the structure is sophisticated, the space occupied is small, and it is widely used in various working environments, reducing the difficulty of operation.
