Description

Technical Field

[0001] This application relates to the field of mechanical manufacturing tools, and in particular, to a wheeled integrated quick-change wrench. Background Technology

[0002] The information provided in this section is for the purpose of generally presenting the background of this application. To the extent described in this section, the work of the currently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly considered to be prior art of this application.

[0003] In the field of aerospace component manufacturing, especially in the machining of aero-engine casing components, the high operating temperature and high mechanical performance requirements of the parts mean that the materials used are generally difficult to machine, such as forged high-temperature alloys, cast high-temperature alloys, and titanium alloys. At the same time, the material removal rate is high, resulting in a huge consumption of cutting tools. During the rough machining stage of the parts, the cutting tools need to be replaced regularly to ensure that the wear of the cutting tools is within the standard requirements.

[0004] The installation method for machine-clamped blades and tool holders involves threaded connections and clamping plates. Loosening and tightening the screws requires a wrench of the corresponding size; however, different tools generally require different wrenches. Commonly used wrenches include 1.5mm, 2mm, 2.5mm, 3mm, 4mm, and 5mm Allen wrenches. On the one hand, the variety and small size of these wrenches lead to a cluttered workbench and easy loss, causing significant inconvenience in daily tool management. On the other hand, changing several blades simultaneously requires preparing several wrenches, resulting in inefficient and slow operations. Therefore, it is necessary to invent a portable, quick-change tool to solve these problems.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] In view of at least one of the above-mentioned technical problems, this application provides a wheeled integrated quick-change wrench that can integrate multiple wrenches into one, achieving the purpose of integration and portability, making it easy to organize and less likely to be lost, while keeping the work site tidy. During use, it allows for quick switching, eliminating the need for workers to carry several wrenches, greatly improving work efficiency.

[0007] According to one aspect of this application, a wheeled integrated quick-change wrench is provided for storing and quickly switching wrenches. The wheeled integrated quick-change wrench includes a mounting body, a pusher, an integrated storage wheel, a handle, and a limit bar.

[0008] The mounting body has a mounting cavity at its bottom and a groove at its top that communicates with the mounting cavity. A limiting groove is provided at the front of the groove, and a limiting hole is provided at the front of the mounting body that communicates with the mounting cavity. A handle is located at the rear of the mounting body, and threaded holes are provided on both the rear of the mounting body and the handle. An integrated storage wheel is rotatably mounted in the mounting cavity. A limiting rod is inserted into a pre-set central shaft hole on the integrated storage wheel after passing through the threaded holes at the handle and the rear of the mounting body in sequence. Wrenches are arranged in a circular array on the outer wall of the integrated storage wheel. The integrated storage wheel also drives each wrench to rotate and enter the groove. A pusher is used to push the wrenches that have entered the groove along the groove so that the working head of the wrench passes through the limiting hole and protrudes to the outside. The pusher is also used to embed into the limiting groove to lock the wrench that has protruded from the limiting hole, and after sliding out of the limiting groove by the pusher, it drives the wrench to return to the integrated storage wheel.

[0009] In some embodiments of this application, the integrated storage wheel includes a roller body. The outer wall of the roller body has a ring array of multiple mounting slots. The front end, rear end and top of the mounting slots are open. The mounting slots are used to install a limit wrench and restrict the wrench to slide only along the axial direction of the roller body.

[0010] In some embodiments of this application, the pusher includes a push rod and a limiting ball. The limiting ball is disposed at the bottom of the push rod. The push rod is used to pass through the groove from the bottom. The diameter of the limiting ball is larger than the width of the groove. The push rod is also used to drive the limiting ball to abut against the wrench and drive the wrench to slide along the groove.

[0011] In some embodiments of this application, the wrench includes a handle portion, a working head is provided at the front end of the handle portion, and an annular limiting groove is provided at the rear side of the handle portion. A limiting ball is used to embed into the limiting groove and drives the entire wrench to slide through a push rod.

[0012] In some embodiments of this application, the handle is provided with a plurality of gripping through holes spaced apart.

[0013] In some embodiments of this application, the wheeled integrated quick-change wrench also includes a wrench storage component. A limiting cavity is provided in the handle. The wrench storage component is slidably disposed in the limiting cavity and locked and limited by a locking component. The wrench storage component has a wrench storage cavity for storing the wrench.

[0014] In some embodiments of this application, one end of the wrench storage component is provided with an extension portion, which is used to extend the overall length of the handle by protruding outside the limiting cavity after the wrench storage component partially slides out of the limiting cavity.

[0015] In some embodiments of this application, a reserved through hole is provided on the extension portion for an external lever to pass through.

[0016] In some embodiments of this application, the locking member includes a first spring latch and a second spring latch spaced apart on the side wall of the wrench holder, and a limiting through hole is provided on the side wall of the limiting cavity. The first spring latch or the second spring latch is used to engage with the limiting through hole to lock and limit the wrench holder.

[0017] In some embodiments of this application, the wrench storage cavity is provided with multiple partitions at intervals.

[0018] This application has the following beneficial effects:

[0019] This application discloses a wheel-type integrated quick-change wrench. The mounting body and handle are combined to form a pistol-like overall structure. The integrated storage wheel is rotatably mounted in the mounting cavity of the mounting body, and the wrenches are arranged in a ring array on the outer wall of the integrated storage wheel and are limited. The integrated storage wheel can drive each wrench to rotate into the slide groove at the top of the mounting body. At this time, the wrench on the integrated storage wheel can be pushed along the slide groove through the limiting hole by the pushing member, so that the working head of the wrench is exposed outside the limiting hole. This makes it convenient to hold the handle and drive the wrench to work. At this time, the wrench also limits the rotation of the integrated storage wheel, making the quick-change wrench device very convenient and labor-saving to operate. The pusher component can be positioned via a limiting groove next to the slide, and it can also limit the wrench's movement after being embedded in the limiting groove. When it is necessary to return the wrench that has protruded from the limiting hole to the integrated storage wheel, simply slide the pusher component out of the limiting groove to move the wrench back. Then, rotate the integrated storage wheel to change to a new wrench, enabling quick and efficient replacement of different wrenches. This application integrates multiple wrenches into one unit, achieving the goals of integration and portability, making them easy to organize and less prone to loss, while maintaining a clean work environment. Quick switching is possible during use, eliminating the need for workers to carry multiple wrenches, greatly improving work efficiency.

[0020] Of course, any product implementing this application does not necessarily need to achieve all the advantages described above simultaneously. In addition to the purposes, features, and advantages described above, this application also has other purposes, features, and advantages.

[0036] A wheel-type integrated quick-change wrench is used to store and quickly switch wrenches 4. The wheel-type integrated quick-change wrench includes a mounting body 1, a pushing component 2, an integrated storage wheel 3, a handle 5, and a limiting rod 6.

[0037] The mounting body 1 has a mounting cavity at its bottom and a sliding groove 12 communicating with the mounting cavity at its top. A limiting groove 13 is formed at the front of the sliding groove 12, and a limiting hole 11 communicating with the mounting cavity is formed at the front of the mounting body 1. A handle 5 is located at the rear of the mounting body 1. Corresponding threaded holes 14 are formed on both the rear of the mounting body 1 and the handle 5. An integrated storage wheel 3 is rotatably mounted within the mounting cavity. A limiting rod 6 passes through the threaded holes 14 at the rear of the handle 5 and the mounting body 1 in sequence before being inserted into the integrated storage wheel 3. Inside the pre-set central shaft hole 32, the wrenches 4 are arranged in a circular array on the outer wall of the integrated storage wheel 3. The integrated storage wheel 3 is also used to drive each wrench 4 to rotate and enter the slide groove 12. The pusher 2 is used to push the wrench 4 that has entered the slide groove 12 along the slide groove 12 so that the working head 43 of the wrench 4 passes through the limiting hole 11 and protrudes to the outside. The pusher 2 is also used to embed into the limiting groove 13 to lock the wrench 4 that has passed through the limiting hole 11. After sliding out of the limiting groove 13 by the pusher 2, the wrench 4 is driven to reset back to the integrated storage wheel 3.

[0038] The term "limiting hole 11" here refers to a through hole structure opened at the front of the mounting body 1. In some embodiments, the limiting hole 11 is a hexagonal hole structure, which facilitates the use of a hexagonal wrench structure wrench 4 to limit its movement.

[0039] This application discloses a wheel-type integrated quick-change wrench. The mounting body 1 and handle 5 are combined to form a pistol-like overall structure. The integrated storage wheel 3 is rotatably mounted in the mounting cavity of the mounting body 1. The wrenches 4 are arranged in a circular array on the outer wall of the integrated storage wheel 3 and are limited. The integrated storage wheel 3 can drive each wrench 4 to rotate into the slide groove 12 at the top of the mounting body 1. At this time, the pusher 2 can push the wrench 4 on the integrated storage wheel 3 along the slide groove 12 and push it out of the limiting hole 11, so that the working head 43 of the wrench is exposed outside the limiting hole 11. This makes it convenient to hold the handle 5 and drive the wrench 4 for work. At this time, the wrench 4 also restricts the rotation of the integrated storage wheel 3, making the quick-change wrench device very convenient and labor-saving to operate. The pusher 2 can be positioned by the limiting groove 13 next to the slide groove 12. At the same time, the pusher 2 can also limit the wrench 4 after being embedded in the limiting groove 13. When it is necessary to reset the wrench that has passed through the limiting hole 11 back to the integrated storage wheel 3, simply slide the pusher 2 out of the limiting groove 13 and drive the wrench 4 back. Then, by rotating the integrated storage wheel 3, a new wrench 4 can be replaced. This allows for quick replacement of different wrenches 4, making the operation very efficient and convenient.

[0040] Preferably, please refer to Figure 6 , 9 As shown, the integrated storage wheel 3 includes a roller body. The outer wall of the roller body has a ring array of multiple mounting slots 31. The front end, rear end and top of the mounting slots 31 are open. The mounting slots 31 are used to install the limit wrench 4 and restrict the wrench 4 to slide only along the axial direction of the roller body.

[0041] Understandably, multiple wrenches 4 can be inserted into the mounting slots 31 for installation and storage. The openings at both ends of the mounting slots 31 facilitate the movement of the wrenches 4 back and forth for loading and unloading. The opening at the top of the mounting slots 31 allows the pusher 2 to enter the mounting slots 31 and engage with the limiting slots 41 of the wrenches 4, and facilitates the pusher 2 to drive the wrenches 4 to slide axially along the roller body.

[0042] In some embodiments, the wrench 4 is a hexagonal wrench, the handle portion 42 is a hexagonal structure, and the cross-section of the mounting groove 31 is also a hexagonal structure to cooperate with the handle portion 42, which can ensure the overall positioning of the wrench 4.

[0043] Preferably, please refer to Figure 5 , 7 As shown, the pusher 2 includes a push rod and a limiting ball. The limiting ball is located at the bottom of the push rod. The push rod is used to pass through the slide groove 12 from the bottom. The diameter of the limiting ball is larger than the width of the slide groove 12. The push rod is also used to drive the limiting ball to abut against the wrench 4 and drive the wrench 4 to slide along the slide groove 12.

[0044] Specifically, the wrench 4 includes a handle portion 42, a working head 43 is provided at the front end of the handle portion 42, and an annular limiting groove 41 is provided on the rear side of the handle portion 42. The limiting ball is used to embed into the limiting groove 41 and drives the wrench 4 as a whole to slide through the push rod.

[0045] It is understandable that the pusher 2 can be driven to slide as a whole by inserting the limit ball into the limit slot 41, and the structure of the limit ball can facilitate the pusher 2 to rotate around the axis of the wrench 4 so that the push rod can be inserted into the limit slot 13.

[0046] It should be noted that the push rod is a flat, long rod structure, and a limiting platform is provided at the top of the push rod. The length of the limiting platform is greater than the width of the slide groove 12. After the push rod passes through the bottom of the slide groove 12, rotating the push rod can limit the push rod through the limiting platform.

[0047] In one embodiment, please refer to Figure 1 , 2 As shown in Figures 3 and 4, the handle 5 has multiple gripping holes spaced apart.

[0048] Understandably, the grip through hole allows the operator's fingers to easily pass through and grip the handle 5, while also reducing weight.

[0049] In another embodiment, please refer to Figure 10 , 11 As shown, the wheel-type integrated quick-change wrench also includes a wrench storage component 7. A limiting cavity 51 is provided in the handle 5. The wrench storage component 7 is slidably disposed in the limiting cavity 51 and the two are locked and limited by a locking component. A wrench storage cavity 72 is provided on the wrench storage component 7 for storing the wrench 4.

[0050] It is understandable that the wrench storage component 7 can hold more wrenches 4, and then by pushing the wrench storage component 7 into the limiting cavity 51 for locking and limiting, more different wrenches 4 can be centrally stored, and different wrenches 4 can be easily replaced to the integrated storage wheel 3 for use, which is beneficial to improving the overall adaptability of the device of this application.

[0051] Preferably, please refer to Figure 10 As shown, one end of the wrench storage component 7 is provided with an extension portion 71. The extension portion 71 is used to extend the overall length of the handle 5 after the wrench storage component 7 partially slides out of the limiting cavity 51 and protrudes outside the limiting cavity 51.

[0052] Understandably, by pushing a portion of the wrench storage piece 7 out to the outside of the limiting cavity 51 and limiting it, the overall length of the handle 5 can be extended, that is, the torque can be extended, making it more convenient for the operator to use, which helps to reduce the labor intensity of turning the wrench 4 and save workers' strength.

[0053] Alternatively, please refer to Figure 10 As shown, the extension 71 has a reserved through hole 73, which is used for the external lever to pass through.

[0054] Understandably, by inserting a longer lever through the pre-drilled hole 73, the operator's ease of operation and effort in turning the wrench 4 to tighten the parts can be further improved, which is conducive to expanding the application scenarios of the device.

[0055] Preferably, please refer to Figure 11 As shown, the locking component includes a first spring latch 74 and a second spring latch 75 spaced apart on the side wall of the wrench holder 7. A limiting through hole 52 is provided on the side wall of the limiting cavity 51. The first spring latch 74 or the second spring latch 75 is used to engage with the limiting through hole 52 to lock and limit the wrench holder 7.

[0056] Understandably, the first spring latch 74 is positioned near the bottom of the wrench holder 7, allowing it to be locked and limited after the wrench holder 7 is fully inserted into the limiting cavity 51. When the extension 71 of the wrench holder 7 needs to be exposed, the wrench holder 7 is pulled out while the first spring latch 74 is pressed, and then the second spring latch 75 is engaged with the limiting through hole 52, allowing the extension 71 to be exposed before the entire wrench holder 7 is locked in place. The operator can use a push bar inserted into the limiting through hole 52 to easily press either the first spring latch 74 or the second spring latch 75.

[0057] Optionally, the wrench storage cavity 72 is provided with multiple partitions at intervals.

[0058] Understandably, the partition can separate the wrenches 4 in the wrench storage cavity 72, reducing the impact damage between the wrenches 4 and also reducing noise during use.
