Description

Technical Field

[0001] This utility model relates to the field of automatic installation technology of wire thread inserts, specifically a quick-change tooling for installing wire thread inserts. Background Technology

[0002] Wire thread inserts are a new type of internal thread fastener suitable for threaded connections. They are screwed into and tightened in the threaded hole of one of the connected parts, forming a standard internal thread. Bolts are then screwed into them. Also known as threaded inserts, or simply inserts, they are spring-shaped concentric bodies with internal and external threads, precisely machined from high-strength, high-precision, and smooth-surfaced cold-rolled diamond-shaped stainless steel wire. They are mainly used to reinforce and protect the internal threads of low-strength materials.

[0003] Based on the above, the inventors have discovered the following problems: The installation of wire thread inserts on the housings of various components of current aero-engines is a relatively important and numerous step in the entire assembly process. In the past, the wire thread inserts were usually installed manually on a workbench. A housing often has multiple specifications and models of wire thread inserts, and workers need to constantly change the insert screwing tools. The process is cumbersome, inefficient, and labor-intensive, making it inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a quick-change tooling for installing wire thread inserts to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-change tooling for installing wire thread inserts and bits, so as to solve the problems mentioned in the background art.

[0006] A quick-change tooling for installing wire thread inserts includes a quick-change assembly and a locking assembly. The quick-change assembly includes a base and a fixed plate. Several side plates are fixedly installed between the base and the fixed plate. Several fixing slots are formed at the bottom of the fixed plate. The fixing slots are arranged between the side plates. A bit assembly is installed inside the fixing slots. The locking assembly includes a locking seat and a quick-change sleeve. A locking hole is formed at one end of the quick-change sleeve, and a floating ring is fitted on the outer side of the end of the quick-change sleeve with the locking hole. A ball groove is formed on the outer side of the locking hole, and a steel ball is placed inside the ball groove. The bit assembly includes a quick-change rod. A connecting groove is formed on the outer side of the quick-change rod. First cylinders are fixedly installed on the outer side plates at both ends of the fixed plate. Push plates are fixedly installed at the output ends of the two first cylinders. A through groove is formed at the bottom of the push plate, and a push step is formed inside the through groove.

[0007] By adopting the above technical solution, the quick-change component and locking component facilitate the quick-change component to accommodate the bit assembly, and the locking component to easily access and replace the bit assembly. The side plate, in conjunction with the base and fixing plate, allows for the formation of several storage spaces for the bit assembly. The fixing slots facilitate the fixing of different bit assemblies inside the quick-change component, making it easy to access and replace the locking component. The locking seat facilitates the fixed connection of the locking component to the robot's moving end, enabling the robot to automatically install wire thread inserts using the locking component. The locking socket allows the quick-change rod to be inserted into the locking socket, facilitating the fixed connection between the locking component and the bit assembly and controlling the automatic installation of the wire thread insert by the bit assembly. The floating ring, fitted outside the ball groove, guides the steel ball into the locking socket. The inner side pushes and fixes the steel ball into the connecting groove, thereby fixing the quick-change rod of the bit assembly inside the locking socket. The quick-change rod and connecting groove facilitate fixing on the locking assembly, allowing the locking assembly to automatically install the wire thread sleeve onto the bit assembly. The first cylinder controls the forward and backward movement of the push plate. The through groove allows the robot to insert the bit assembly into the controlled fixing slot when replacing it. The push step allows the first cylinder to control the push plate to move away from the fixing plate when replacing the bit assembly. During this process, the push step blocks the floating ring, releasing the floating ring from locking the steel ball. This allows the quick-change rod to be pulled out of the locking socket, enabling disassembly of the bit assembly for subsequent installation.

[0008] Furthermore, a fixing block is fixedly installed at the end of the quick-change rod away from the connecting groove, and the fixing block engages with the fixing slot.

[0009] By adopting the above technical solution, the bit assembly is easily fixed inside the quick-change assembly by engaging the fixing block and the fixing slot. This allows the quick-change assembly to store the bit assembly for replacement by the locking assembly.

[0010] Furthermore, a locking groove is provided on the outer side of the fixing block, and an installation bit is fixedly installed on the end of the fixing block away from the quick-change rod.

[0011] By adopting the above technical solution, the locking groove allows the locking plate to secure the fixing block inside the fixing slot, preventing the bit assembly from loosening inside the quick-change assembly. The installed bit is used to perform the tightening task of the wire thread insert. Different models of bit assemblies are equipped with different models of installed bits.

[0012] Furthermore, a mounting bracket and a rotating bracket are fixedly installed on the top of the locking seat. An electric screwdriver is fixedly installed on one side of the mounting bracket, and a rotating sleeve is fixedly installed on one side of the rotating bracket.

[0013] By adopting the above technical solution, the installation bracket and rotating bracket facilitate the fixing of the electric screwdriver and rotating sleeve on the locking seat.

[0014] Furthermore, the rotating sleeve is fitted on the outside of the quick-change sleeve, the quick-change sleeve is rotatably connected to the rotating sleeve, and a coupling is fixedly installed at the output end of the electric screwdriver, the other end of the coupling is fixedly connected to the quick-change sleeve.

[0015] By adopting the above technical solution and using the coupling, the electric screwdriver can drive the quick-change sleeve to rotate, thereby controlling the bit assembly installed on the quick-change sleeve to perform the tightening task.

[0016] Furthermore, a fixing ring is fixedly installed on the middle of the outer side of the quick-change sleeve, a push spring is fixedly installed on one side of the fixing ring, and the other end of the push spring is fixedly connected to the floating ring.

[0017] By adopting the above technical solution, and by setting up the push spring, when the first cylinder drives the floating plate close to the fixed plate after the replacement of the bit assembly, the push spring provides elastic force to push the floating ring back to reset, and pushes and fixes the steel ball, thereby fixing and locking the bit assembly.

[0018] Furthermore, a fixing frame is fixedly installed on the top of the side plate located in the middle of the fixing plate, a second cylinder is fixedly installed on the top of the fixing frame, and a floating plate is fixedly installed on the output end of the second cylinder.

[0019] By adopting the above technical solution and setting the fixing frame, it is easy to fix the second cylinder on the top of the side plate, which facilitates the operation of the second cylinder to control the up and down movement of the floating plate.

[0020] Furthermore, the top of the fixed plate has several slots, and several locking pieces are fixedly installed on one side of the floating plate. The locking pieces are inserted into the slots and are engaged with the locking slots.

[0021] By adopting the above technical solution, the locking plate is designed to facilitate the up-and-down movement of the floating plate, which in turn moves the locking plate up and down. When replacing the bit assembly, the floating plate rises, causing the locking plate to rise, which facilitates the insertion of the fixing block into the fixing slot. After the insertion of the bit assembly to be removed is completed, the floating plate moves the locking plate down to lock the fixing block into the fixing slot, which facilitates the removal of the locking assembly to perform the installation of the new bit assembly. After the installation is completed, the floating plate moves the locking plate up, which facilitates the removal of the bit assembly by the locking assembly.

[0022] Furthermore, a wiring terminal is fixedly installed on one side of the middle part of the base, and two photoelectric sensors are fixedly installed on the side plate facing the bit assembly.

[0023] By adopting the above technical solution, the wiring terminals and photoelectric sensors facilitate electrical connections and power and signal transmission. The photoelectric sensors facilitate the detection of the position of the bit assembly, ensuring its correct installation or replacement and playing a foolproof role.

[0024] Furthermore, a solenoid valve is fixedly installed on the top of the side plate at one end of the base, and the output end of the solenoid valve is connected to the first cylinder and the second cylinder respectively.

[0025] By adopting the above technical solution and setting the solenoid valve, it is convenient to connect the first cylinder and the second cylinder to the external air source, and to control the operation of the first cylinder and the second cylinder.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: The quick-change component and locking component facilitate the quick-change component to accommodate the bit assembly, and the locking component to easily access and replace the bit assembly. The side plate facilitates the formation of several accommodating spaces with the base and fixing plate, making it convenient to store the bit assembly. The fixing slot facilitates the fixing of different types of bit assemblies inside the quick-change component, facilitating the access and replacement of the locking component. The locking seat facilitates the fixed connection of the locking component to the robot's moving end, allowing the robot to automatically install the wire thread insert using the locking component. The locking hole facilitates the insertion of the quick-change rod into the locking hole, facilitating the fixed connection between the locking component and the bit assembly, and controlling the automatic installation of the wire thread insert by the bit assembly. The floating ring, fitted on the outside of the ball groove, pushes and fixes the steel ball towards the inside of the locking hole, causing the steel ball to engage inside the connecting groove. The invention achieves a quick-change lever for the bit assembly, which is fixedly installed inside the locking socket. The quick-change lever and connecting groove facilitate secure installation on the locking assembly, allowing the locking assembly to automatically install the bit assembly onto the wire thread insert. The first cylinder controls the forward and backward movement of the push plate. The through slot allows the robot to insert the bit assembly into the controlled fixed slot during replacement. The push step, controlled by the first cylinder, moves the push plate away from the fixed plate during replacement, causing the push step to block the floating ring as the locking assembly inserts the bit assembly into the fixed slot. This releases the floating ring from the steel ball, allowing the quick-change lever to be easily pulled out of the locking socket, facilitating the disassembly of the bit assembly and subsequent installation. This invention automatically disassembles and replaces bits, offering convenient operation, improved work efficiency, and high practical value. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-6This utility model provides a technical solution: a quick-change tooling for installing screwdriver bits with wire thread inserts, including a quick-change component 1 and a locking component 2. The quick-change component 1 and locking component 2 facilitate the quick-change component 1 to accommodate screwdriver bit components 3, and the locking component 2 to easily access and replace the screwdriver bit components 3. The quick-change component 1 includes a base 11 and a fixing plate 12. Several side plates 13 are fixedly installed between the base 11 and the fixing plate 12. The side plates 13 facilitate the formation of several accommodating spaces with the base 11 and the fixing plate 12, making it convenient to store the screwdriver bit components 3. The bottom of the fixing plate 12 has several fixing slots 113, which facilitate the fixing of different types of screwdriver bit components 3 inside the quick-change component 1, making it convenient for the locking component 2 to access and replace them. For use and replacement, a fixing slot 113 is set between the side plates 13. The fixing slot 113 contains a bit assembly 3. The locking assembly 2 includes a locking seat 21 and a quick-change sleeve 29. The locking seat 21 facilitates the fixed connection between the locking assembly 2 and the robot's moving end, allowing the robot to automatically install wire thread inserts. One end of the quick-change sleeve 29 has a locking hole 211, which allows the quick-change rod 32 to be inserted, facilitating the fixed connection between the locking assembly 2 and the bit assembly 3.

A first cylinder 16 is fixedly installed on the outer side of the side plates 13 at both ends of the fixed plate 12. The first cylinder 16 facilitates the control of the forward and backward movement of the push plate 18. Two first cylinders 16 have push plates 18 fixedly mounted at their output ends. The bottom of the push plate 18 has a through groove 19. This through groove 19 facilitates the insertion of the bit assembly 3 into the controlled fixed slot 113 by the robot when replacing it. The through groove 19 has a push step 110. This push step 110 allows the first cylinder 16 to control the push plate 18 to move away from the fixed plate 12 when replacing the bit assembly 3. During this process, as the locking assembly 2 inserts the bit assembly 3 into the fixed slot 113, the push step 110 blocks the floating ring 28, releasing the floating ring 28 from locking the steel ball 213. This allows the quick-change lever 32 to be easily pulled out of the locking hole 211, enabling the disassembly of the bit assembly 3.This will facilitate subsequent installation.

The output end of the electric screwdriver 24 is fixedly installed with a coupling 25, and the other end of the coupling 25 is fixedly connected to the quick-change sleeve 29. The setting of the coupling 25 facilitates the operation of the electric screwdriver 24 to drive the quick-change sleeve 29 to rotate, thereby controlling the bit assembly 3 installed on the quick-change sleeve 29 to perform the tightening task.

[0040] Among them, a fixing ring 27 is fixedly installed on the middle of the outer side of the quick-change sleeve 29, and a push spring 210 is fixedly installed on one side of the fixing ring 27. The other end of the push spring 210 is fixedly connected to the floating ring 28. With the setting of the push spring 210, when the first cylinder 16 drives the floating plate 115 to approach the fixing plate 12 after the replacement of the bit assembly 3, the push spring 210 provides elastic force to push the floating ring 28 back to reset, and pushes and fixes the steel ball 213, thereby fixing and locking the bit assembly 3.

[0041] A fixing frame 111 is fixedly installed on the top of the side plate 13 located in the middle of the fixing plate 12. A second cylinder 17 is fixedly installed on the top of the fixing frame 111. A floating plate 115 is fixedly installed on the output end of the second cylinder 17. The fixing frame 111 facilitates the fixing of the second cylinder 17 on the top of the side plate 13, making it convenient for the second cylinder 17 to control the floating plate 115 to move up and down.

[0042] The fixed plate 12 has several slots 114 on its top, and several locking pieces 116 are fixedly installed on one side of the floating plate 115. The locking pieces 116 are inserted into the slots 114 and are engaged with the locking grooves 35. The locking pieces 116 facilitate the up-and-down movement of the floating plate 115, which in turn moves the locking pieces 116 up and down. When replacing the bit assembly 3, the floating plate 115 rises, causing the locking pieces 116 to rise, which makes it easier for the fixing block 34 to be inserted into the fixing slot 113. After the insertion of the bit assembly 3 to be removed is completed, the floating plate 115 drives the locking pieces 116 to fall and lock the fixing block 34 into the fixing slot 113, which makes it easier for the locking assembly 2 to be pulled out to install the new bit assembly 3. After the installation is completed, the floating plate 115 drives the locking pieces 116 to rise, which makes it easier for the locking assembly 2 to pull out the bit assembly 3.

[0043] A terminal block 112 is fixedly installed on one side of the middle part of the base 11, and two photoelectric sensors 14 are fixedly installed on the side plate 13 facing the bit assembly 3. The terminal block 112 and the photoelectric sensors 14 facilitate electrical connection and power and signal transmission. The photoelectric sensors 14 facilitate detection of the position of the bit assembly 3, ensuring its correct installation or replacement and playing a foolproof role.

[0044] A solenoid valve 15 is fixedly installed on the top of the side plate 13 at one end of the base 11. The output end of the solenoid valve 15 is connected to the first cylinder 16 and the second cylinder 17 respectively. The solenoid valve 15 facilitates the connection of the first cylinder 16 and the second cylinder 17 to an external air source, making it convenient to control the operation of the first cylinder 16 and the second cylinder 17.

[0045] Specifically, the working principle of this quick-change tool for installing screwdriver bits with wire thread inserts is as follows: During use, the wiring terminal 112 and photoelectric sensor 14 facilitate electrical connection, power and signal transmission. The photoelectric sensor 14 detects the position of the bit assembly 3, ensuring correct installation or replacement and preventing mistaken identification. The solenoid valve 15 connects the first cylinder 16 and the second cylinder 17 to an external air source, facilitating control of their operation. The side plate 13, in conjunction with the base 11 and the fixing plate 12, forms several accommodating spaces for storing the bit assembly 3. The fixing slot 113 allows for the fixing of different types of bit assemblies 3 onto the quick-change assembly 1. Internally, the locking assembly 2 is easily accessible and replaceable. The locking seat 21 facilitates the fixed connection between the locking assembly 2 and the robot's mobile end, allowing the robot to automatically install wire thread inserts using the locking assembly 2. The mounting bracket 22 and rotating bracket 23 facilitate the fixed installation of the electric screwdriver 24 and rotating sleeve 26 onto the locking seat 21. The coupling 25 allows the electric screwdriver 24 to drive the quick-change sleeve 29 to rotate, thereby controlling the bit assembly 3 mounted on the quick-change sleeve 29 to perform the tightening task. The locking hole 211 allows the quick-change rod 32 to be inserted into the locking hole 211, facilitating the fixed connection between the locking assembly 2 and the bit assembly 3, and controlling the bit assembly 3 to automatically install the wire thread inserts. The floating ring 28 is designed to be fitted onto the outside of the ball groove 212, pushing and fixing the steel ball 213 towards the inside of the locking hole 211, causing the steel ball 213 to engage with the connecting groove 33. This allows the quick-change rod 32 of the bit assembly 3 to be fixedly installed inside the locking hole 211. The fixing block 34 engages with the fixing slot 113, facilitating the fixing of the bit assembly 3 inside the quick-change assembly 1. This allows the quick-change assembly 1 to store the bit assembly 3 for replacement by the locking assembly 2. The locking groove 35 allows the locking piece 116 to fix the fixing block 34 inside the fixing slot 113, preventing the bit assembly 3 from loosening inside the quick-change assembly 1. The bit 31 is installed to perform the tightening task of the wire thread insert. Different models of bit assemblies 3 have different sizes of... The screwdriver bit 31 is installed on the locking assembly 2 via the quick-change rod 32 and connecting groove 33. This facilitates the automatic installation of the screwdriver bit assembly 3 onto the wire thread insert via the locking assembly 2. The first cylinder 16 controls the forward and backward movement of the push plate 18. The through groove 19 allows the robot to insert the screwdriver bit assembly 3 into the controlled fixing slot 113 when replacing it. The push step 110 allows the first cylinder 16 to control the push plate 18 to move away from the fixing plate 12 when replacing the screwdriver bit assembly 3. During this process, the push step 110 blocks the floating ring 28, releasing the floating ring 28 from locking the steel ball 213.The quick-change lever 32 can be easily pulled out from the locking socket 211 to disassemble the bit assembly 3, facilitating subsequent installation. The push spring 210 facilitates the replacement of the bit assembly 3. When the first cylinder 16 moves the floating plate 115 close to the fixed plate 12 after replacing the bit assembly 3, the push spring 210 provides elasticity to push the floating ring 28 back to its original position, thus fixing the steel ball 213 and securing the bit assembly 3. The fixing bracket 111 facilitates the fixed installation of the second cylinder 17 on the top of the side plate 13, allowing the second cylinder 17 to control the up-and-down movement of the floating plate 115. The locking plate 116 is designed to allow the floating plate 115 to move up and down, thus moving the locking plate 116 up and down as well. When replacing the bit assembly 3, the floating plate 115 rises, causing the locking plate 116 to rise, facilitating the insertion of the fixing block 34 into the fixing slot 113. After the insertion of the bit assembly 3, the floating plate 115 lowers the locking plate 116, locking the fixing block 34 into the fixing slot 113. This allows the locking assembly 2 to be easily removed to install the new bit assembly 3. After installation, the floating plate 115 raises the locking plate 116, allowing the locking assembly 2 to easily remove the bit assembly 3.
