Description

Technical Field

[0001] This application relates to the field of automation technology, and in particular to a quick-change sleeve mechanism. Background Technology

[0002] In automated equipment, sleeve replacement at automatic workstations is generally done manually or via a gun-changing disc. Manual sleeve replacement is inefficient, while replacing sleeves via a gun-changing disc is costly, and there are areas for improvement. Utility Model Content

[0003] In order to improve the efficiency of automatic sleeve changing and save the cost of sleeve changing, this application provides a sleeve quick-change mechanism.

[0004] The quick-change sleeve mechanism provided in this application adopts the following technical solution: A quick-change sleeve mechanism mainly includes a mounting base, on which a mounting bracket is detachably mounted. The mounting bracket includes several U-shaped connecting parts, each of which has a locking groove formed inside to match the annular groove on the sleeve, and the opening of the locking groove is located on the side of the U-shaped connecting part away from the mounting base. Each of the U-shaped connectors is equipped with an auxiliary detection mechanism for detecting the position of the sleeve.

[0005] By adopting the above technical solution and using the U-shaped connector, when a sleeve needs to be replaced, the robot moves the sleeve at the bottom of the tightening gun to the U-shaped connector next to the new sleeve. After the robot inserts the sleeve into the locking groove, it separates the sleeve from the tightening gun and connects the tightening gun to the quick-change female head of the new sleeve on the side. Separating the sleeve from the locking groove achieves automatic sleeve switching, eliminating the need for manual sleeve replacement and ensuring the efficiency of sleeve replacement with the tightening gun. Furthermore, the sleeve replacement mechanism is simple in structure and lower in cost compared to a gun-changing disc. In addition, since auxiliary detection mechanisms are installed on both sides of the U-shaped connector, they help the robot sense the position of the sleeve, improving the accuracy of the robot's sleeve replacement action.

[0006] Preferably, the U-shaped connecting part includes two support rods integrally formed on the mounting bracket, and the locking groove is formed between the two support rods; Both of the support rods have inclined surfaces on the inner walls of their ends near the openings of the lock grooves, and the inclined surfaces slope outward toward the openings of the lock grooves.

[0007] By adopting the above technical solution, when the sleeve is inserted into the locking groove, the two support rods are limited to the annular groove of the sleeve, which can fix the position of the sleeve. By setting the inclined surface on the support rod, the sleeve and the end of the support rod can be prevented from colliding during the process of the robot inserting the sleeve into the locking groove, which can improve the smoothness of the robot's sleeve placement action.

[0008] Preferably, the side of the U-shaped connector opposite to the mounting base is formed with an arc-shaped groove that matches the sleeve.

[0009] By adopting the above technical solution, the arc-shaped groove is adapted to the cylindrical sleeve, which can improve the compactness between the sleeve and the U-shaped connection.

[0010] Preferably, the auxiliary detection mechanism includes a first position sensor and a second position sensor, the first position sensor being located above the second position sensor, the first position sensor being used to detect the quick-change female end of the sleeve, and the first position sensor being used to detect the quick-change male end of the sleeve.

[0011] By adopting the above technical solution, during the placement or removal of the sleeve, the first position sensor and the second position sensor can detect the position of the quick-change male and quick-change female connectors on the sleeve in real time, so that the robot can judge the position of the sleeve. The position detection data of the quick-change male and quick-change female connectors assists the robot in accurately performing the action of picking up and placing the sleeve.

[0012] Preferably, the auxiliary detection mechanism further includes a U-shaped bracket, which includes a first mounting plate and a second mounting plate that are parallel to each other. The first mounting plate is mounted above the second mounting plate, and the second mounting plate is bolted to a mounting base. The first position sensor is bolted to the top of the first mounting plate, and the second position sensor is bolted to the top of the second mounting plate.

[0013] By adopting the above technical solution and using the U-shaped bracket, the first position sensor and the second position sensor can be easily installed.

[0014] In summary, the quick-change sleeve mechanism of this application has at least one of the following beneficial technical effects: 1. With the U-shaped connector, when the sleeve needs to be replaced, the robot moves the sleeve at the bottom of the tightening gun to the U-shaped connector next to the new sleeve. After the robot inserts the sleeve into the locking groove, the robot separates the sleeve from the tightening gun and connects the tightening gun to the quick-change female head of the new sleeve next to it. After the sleeve is separated from the locking groove, the automatic sleeve switching action can be realized, which can eliminate the need for manual sleeve replacement, ensure the efficiency of tightening gun sleeve replacement, and the sleeve replacement mechanism is simple and has a lower cost compared to the gun changing disc. 2. During the placement or removal of the sleeve, the first position sensor and the second position sensor can detect the position of the quick-change male and quick-change female connectors on the sleeve in real time, so that the robot can determine the position of the sleeve. The position detection data of the quick-change male and quick-change female connectors assists the robot in accurately performing the action of picking up and placing the sleeve.

[0018] The following combination Figures 1-2 This application will be described in further detail.

[0019] Example This application discloses a quick-change sleeve mechanism. (Refer to...) Figure 1 It mainly includes a mounting base 1, and a mounting bracket 2 is detachably installed on the side wall of the mounting base 1. The mounting bracket 2 includes several U-shaped connecting parts 3. Each U-shaped connecting part 3 has a locking groove 31 that is adapted to the annular groove 51 on the sleeve 5, and the opening of the locking groove 31 is located on the side of the U-shaped connecting part 3 away from the mounting base 1. An auxiliary detection mechanism 4 for detecting the position of the sleeve 5 is installed on the side of each U-shaped connecting part 3.

[0020] With the U-shaped connecting part 3, when the sleeve 5 needs to be replaced, the robot moves the sleeve 5 at the bottom of the tightening gun 6 to the U-shaped connecting part 3 next to the new sleeve 5. After the robot inserts the sleeve 5 into the locking groove 31, the robot separates the sleeve 5 from the tightening gun 6 and connects the tightening gun 6 to the quick-change female head 52 of the new sleeve 5 on the side. After the sleeve 5 is separated from the locking groove 31, the automatic switching action of the sleeve 5 can be realized, which can eliminate the need for manual replacement of the sleeve 5, ensure the efficiency of the tightening gun 6 in replacing the sleeve 5, and the mechanism for replacing the sleeve 5 is simple and has a lower cost compared to the gun changing disc.

[0021] In addition, since auxiliary detection mechanisms 4 are installed on both sides of the U-shaped connecting part 3, they can help the robot sense the position of the sleeve 5 and improve the accuracy of the robot's sleeve replacement action.

[0022] Reference Figure 1 and Figure 2 The U-shaped connecting part 3 includes two support rods 32 integrally formed on the mounting bracket 2, and a locking groove 31 is formed between the two support rods 32; the inner walls of the ends of the two support rods 32 near the opening of the locking groove 31 are provided with inclined surfaces 33, and the inclined surfaces 33 are inclined outward in the direction of the opening of the locking groove 31.

[0023] By adopting the above technical solution, when the sleeve 5 is inserted into the locking groove 31, the two support rods 32 are limited to the annular groove 51 of the sleeve 5, which can fix the position of the sleeve 5. By setting the inclined surface 33 on the support rod 32, the sleeve 5 and the end of the support rod 32 can be prevented from colliding during the process of the robot inserting the sleeve 5 into the locking groove 31, which can improve the smoothness of the robot's sleeve placement action.

[0024] Reference Figure 2 The U-shaped connecting part 3 has an arc-shaped groove 34 that is adapted to the sleeve 5 on the side opposite to the mounting base 1.

[0025] The arc-shaped groove 34 is adapted to the cylindrical sleeve 5, which can improve the tightness between the sleeve 5 and the U-shaped connecting part 3.

[0026] Reference Figure 1 The auxiliary detection mechanism 4 includes a first position sensor 41 and a second position sensor 42, and the signal output terminals of the first position sensor 41 and the second position sensor 42 are connected to the control module of the robot. The first position sensor 41 is located above the second position sensor 42. The first position sensor 41 is used to detect the quick-change female head 52 of the sleeve 5 and the quick-change male head 53 of the sleeve 5.

[0027] During the placement or removal of the sleeve 5, the first position sensor 41 and the second position sensor 42 can detect the positions of the quick-change male connector 53 and quick-change female connector 52 on the sleeve 5 in real time, so that the robot can judge the position of the sleeve 5. The position detection data of the quick-change male connector 53 and quick-change female connector 52 assists the robot in accurately performing the action of picking up and placing the sleeve 5.

[0028] Reference Figure 1The auxiliary detection mechanism 4 also includes a U-shaped bracket 43 for mounting the first position sensor 41 and the second position sensor 42. The U-shaped bracket 43 includes a first mounting plate 431 and a second mounting plate 432 that are parallel to each other (the U-shaped bracket 43 is integrally bent from a single piece of steel). The first mounting plate 431 is mounted above the second mounting plate 432, and the second mounting plate 432 is bolted to the mounting base 1. The first position sensor 41 is bolted to the top of the first mounting plate 431, and the second position sensor 42 is bolted to the top of the second mounting plate 432. The U-shaped bracket 43 facilitates the mounting of the first position sensor 41 and the second position sensor 42.

[0029] The implementation principle of the quick-change sleeve mechanism in this application embodiment is as follows: Through the U-shaped connecting part 3, when the sleeve 5 needs to be replaced, the robot moves the sleeve 5 at the bottom of the tightening gun 6 to the U-shaped connecting part 3 beside the new sleeve 5. After the robot inserts the sleeve 5 into the locking groove 31, the robot separates the sleeve 5 from the tightening gun 6 and connects the tightening gun 6 to the quick-change female head 52 of the new sleeve 5 beside it. Separating the sleeve 5 from the locking groove 31 enables automatic sleeve switching, eliminating the need for manual sleeve replacement and ensuring the efficiency of the tightening gun 6 in changing the sleeve 5. Furthermore, the sleeve replacement mechanism has a simple structure and is less expensive than a gun-changing disc. In addition, since auxiliary detection mechanisms 4 are installed on both sides of the U-shaped connecting part 3, they can assist the robot in sensing the position of the sleeve 5, improving the accuracy of the robot's sleeve replacement action.

[0030] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
