Description

Technical Field

[0001] This utility model relates to the field of electric wrench technology, and in particular to a CNC constant torque electric wrench. Background Technology

[0002] A wrench is a common tool for installation and disassembly. It is a hand tool that uses the lever principle to tighten or loosen bolts, screws, nuts and other threaded fasteners. Wrenches are usually made of structural steel made of carbon or alloy materials. A torque wrench, also known as a torque wrench, is a type of electric wrench that is easy to operate and saves time and effort.

[0003] An existing high-torque electric wrench (announcement number: CN217255945U) has at least the following drawbacks: Although the device can quickly change and install / remove sockets, the wrench body vibrates during use, which can easily cause the sockets to loosen, affecting the performance. It is also not convenient for workers to hold and use, and its stability is not ideal. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a CNC constant torque electric wrench.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A CNC constant torque electric wrench includes a wrench body, a mounting base, and a shock absorber base. A sleeve is movably mounted on the mounting base, and a second reinforcing ring is sleeved on the outside of the sleeve. A first reinforcing ring is located on the side of the second reinforcing ring away from the mounting base. A positioning sleeve is fixedly installed between the first and second reinforcing rings. A movable block is movably mounted on the upper end of the first reinforcing ring. An arc-shaped block is fixedly mounted on the end of the movable block near the inside of the first reinforcing ring. A first spring is fixedly installed between the arc-shaped block and the inner wall of the first reinforcing ring. An elastic block is located inside the positioning sleeve. A telescopic column is hinged between the elastic block and the inner wall of the positioning sleeve. A fixing plate is bolted to the upper end of the shock absorber base. A support column is fixedly installed inside the shock absorber base, and a buffer pad is movably mounted on the support column.

[0007] As a further embodiment of this utility model, a handle is fixedly installed between the lower end of the wrench body and the fixing plate, a locking block is fixedly provided at the bottom end of the fixing plate, and a stud is movably provided at the upper end of the positioning sleeve.

[0008] As a further embodiment of this utility model, the stud is threadedly connected to the positioning sleeve, a spring is fixedly installed on the telescopic column, and the elastic blocks are symmetrically distributed on the positioning sleeve.

[0009] As a further embodiment of this utility model, the top of the support column is connected through the locking block, and a second spring is fixedly installed between the lower end of the buffer pad and the inner wall of the shock absorber seat, with the second spring movably connected to the support column.

[0010] As a further embodiment of this utility model, the arc-shaped blocks are symmetrically distributed on the first reinforcing ring, and the movable block is connected through the first reinforcing ring.

[0011] As a further embodiment of this utility model, the mounting base is fixedly installed at one end of the wrench body, and the reinforcing ring is fixedly connected to the mounting base.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. First, the operator can push the sleeve into the positioning sleeve, reinforcing ring one, and reinforcing ring two. Two sets of arc-shaped blocks are installed inside reinforcing ring one and reinforcing ring two. Using the elasticity of spring one, the movable block is pushed into the interior of reinforcing ring one, clamping the sleeve between the two sets of arc-shaped blocks. After the two ends of the sleeve are initially positioned by reinforcing ring one and reinforcing ring two, the operator manually twists the top of the stud to extend it into the positioning sleeve. With the cooperation of spring three and the telescopic column, the stud moves downward, pushing the elastic block against the sleeve, further clamping and fixing the middle section of the sleeve. Spring three and the telescopic column provide a buffering effect, preventing the sleeve from loosening or falling off when the wrench body is working, while also facilitating quick disassembly and installation.

[0014] 2. After pushing the locking block through the connecting column, the worker uses tools to tighten multiple bolts again to further fix the fixing plate to the shock absorber seat, thus completing the installation of the handle and the shock absorber seat. When the wrench body vibrates during operation, the handle transmits the vibration energy to the shock absorber seat. After the locking block inside the shock absorber seat receives the vibration energy, it pushes the buffer pad down and squeezes the second spring. The compression deformation of the second spring absorbs the vibration energy, reduces interference to the worker, and improves the stability of use. Attached Figure Description

[0024] Reference Figures 1-5A CNC constant torque electric wrench includes a wrench body 1, a mounting base 2, and a shock absorber 4. A sleeve 5 is movably mounted on the mounting base 2. A second reinforcing ring 103 is sleeved on the outside of the sleeve 5. A first reinforcing ring 102 is provided on the side of the second reinforcing ring 103 away from the mounting base 2. A positioning sleeve 101 is fixedly installed between the first reinforcing ring 102 and the second reinforcing ring 103. A movable block 201 is movably mounted on the upper end of the first reinforcing ring 102. An arc-shaped block 202 is fixedly installed on the end of the movable block 201 near the inside of the first reinforcing ring 102. A spring 104 is fixedly installed between the arc-shaped block 202 and the inner wall of the first reinforcing ring 102. An elastic block 203 is provided inside the positioning sleeve 101. A telescopic column 302 is hinged between the elastic block 203 and the inner wall of the positioning sleeve 101. A fixing plate 303 is bolted to the upper end of the shock absorber 4. A support column 7 is fixedly installed inside the shock absorber 4. A buffer pad 8 is movably mounted on the support column 7.

[0025] In use, the operator first pushes the sleeve 5 into the positioning sleeve 101, the first reinforcing ring 102, and the second reinforcing ring 103. Two sets of arc-shaped blocks 202 are installed inside both the first and second reinforcing rings 102 and 103. Using the elasticity of the first spring 104, the movable block 201 is pushed into the first reinforcing ring 102, causing the two sets of arc-shaped blocks 202 to clamp the sleeve 5. The first and second reinforcing rings 102 and 103 provide initial clamping to both ends of the sleeve 5. After positioning, the staff manually twists the top of the stud 105 so that the stud 105 extends into the positioning sleeve 101. With the cooperation of the spring 301 and the telescopic column 302, the stud 105 moves down and pushes the elastic block 203 to press against the sleeve 5, further clamping and fixing the middle section of the sleeve 5. The spring 301 and the telescopic column 302 provide a buffering effect, preventing the sleeve 5 from loosening and falling off when the wrench body 1 is working, while facilitating quick disassembly and installation.

[0026] In this embodiment, a handle 3 is fixedly installed between the lower end of the wrench body 1 and the fixing plate 303, a locking block 6 is fixedly provided at the bottom end of the fixing plate 303, and a stud 105 is movably provided at the upper end of the positioning sleeve 101.

[0027] In use, after pushing the locking block 6 through the connecting column 7, the operator uses tools to tighten multiple bolts to further fix the fixing plate 303 onto the shock absorber 4, thus completing the installation of the handle 3 and the shock absorber 4. When the wrench body 1 vibrates during operation, the handle 3 transmits the vibration energy to the shock absorber 4. After the locking block 6 inside the shock absorber 4 receives the vibration energy, it pushes the buffer pad 8 down and squeezes the second spring 106. The compression deformation of the second spring 106 absorbs the vibration energy, reduces interference to the operator, and improves the stability of use.

[0028] In this embodiment, the stud 105 is threadedly connected to the positioning sleeve 101, the telescopic column 302 is fixedly installed with a spring 301, and the elastic blocks 203 are symmetrically distributed on the positioning sleeve 101.

[0029] During use, when disassembling, the operator can pull the movable block 201 to move it outward. With the cooperation of the spring 104, the movable block 201 drives the arc block 202 away from the sleeve 5, thereby loosening the positioning of the arc block 202 on the sleeve 5. The arc block 202 and the elastic block 203 are made of rubber.

[0030] In this embodiment, the top of the support column 7 is connected to the connecting block 6, and a spring 106 is fixedly installed between the lower end of the buffer pad 8 and the inner wall of the shock absorber 4. The spring 106 is movably connected to the support column 7.

[0031] When in use, the buffer pad 8 is mainly made of foam material. With the cooperation of spring 2 106, it effectively absorbs the vibration and noise generated by the operation of the wrench body 1, reduces the impact on the operator, and makes it easier to hold the handle 3 stably for work.

[0032] In this embodiment, the arc-shaped blocks 202 are symmetrically distributed on the reinforcing ring 102, and the movable blocks 201 are connected through the reinforcing ring 102.

[0033] In use, two sets of arc-shaped blocks 202 are provided inside both the first reinforcing ring 102 and the second reinforcing ring 103 to position the two ends of the sleeve 5 respectively, thereby enhancing the installation effect of the sleeve 5.

[0034] In this embodiment, the mounting base 2 is fixedly installed at one end of the wrench body 1, and the reinforcing ring 2 103 is fixedly connected to the mounting base 2.

[0035] When in use, when the stud 105 moves down to push the elastic block 203, it simultaneously drives the spring 301 and the telescopic column 302 to extend and retract. The spring 301 and the telescopic column 302 provide a buffering effect and strengthen the tightness of the connection.

[0036] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: First, the operator can push the sleeve 5 into the positioning sleeve 101, the first reinforcing ring 102, and the second reinforcing ring 103. Two sets of arc-shaped blocks 202 are provided inside both the first reinforcing ring 102 and the second reinforcing ring 103. Using the elasticity of the first spring 104, the movable block 201 is pushed into the first reinforcing ring 102, causing the two sets of arc-shaped blocks 202 to clamp the sleeve 5. After the first and second reinforcing rings 102 and 103 provide initial positioning for both ends of the sleeve 5, the operator manually twists the top of the stud 105, causing the stud 105 to extend into the positioning sleeve 101. With the cooperation of the third spring 301 and the telescopic column 302, the stud 105 moves downward, pushing the elastic block 203 to press against the sleeve. The sleeve 5 is further clamped and fixed in the middle section. The spring 301 and the telescopic column 302 provide a buffering effect, preventing the sleeve 5 from loosening and falling off when the wrench body 1 is working. At the same time, it facilitates quick disassembly and installation. After pushing the locking block 6 through the connecting column 7, the worker uses tools to turn multiple bolts again to further fix the fixing plate 303 on the shock absorber 4, thus completing the installation of the handle 3 and the shock absorber 4. When the wrench body 1 vibrates during operation, the handle 3 transmits the vibration energy to the shock absorber 4. After the locking block 6 inside the shock absorber 4 receives the vibration energy, it pushes the buffer pad 8 down and squeezes the spring 106. The compression deformation of the spring 106 absorbs the vibration energy, reduces interference to the worker, and improves the stability of use.
