[0027] A torque-controllable air-off straight-handle assembly tool of the present invention comprises a pneumatic assembly component 101 and a disassembly component 102; the disassembly component 102 comprises a shell 103, a connecting end 104, an assembly head 105, a protective frame 106, a ring 107, a top connecting frame 108, an elastic member 109, a rotating shaft 110, a paddle 111, a spring 112, a gripping end 113, a frame 114 and a cover plate 115; the pneumatic assembly component 101 comprises an air motor 118, an output shaft 119, a coupling 120, an output rod 121 and a connecting shaft 122, and the gripping end 113 comprises an insert rod 116 and an anti-slip portion 117. The above-mentioned solution solves the problem that the existing electronic air-off type pneumatic tools adopt the electronic air-off method, so that the pneumatic tools can be used for a long time, which leads to the problem that the tool head of the pneumatic tool is easily damaged during frequent use, affecting the normal assembly work.

[0028] According to the present specific embodiment, the shell 103 is fixedly connected to the pneumatic assembly component 101 and is located at one side of the pneumatic assembly component 101.

The ring 107 is fixedly connected to the connecting end 104 and is located at a side of the connecting end 104 close to the shell 103. When it is needed, the staff starts the pneumatic assembly component 101 by holding the shell 103, drives the connecting end 104 to operate, and makes the assembly head 105 operate accordingly, so that the workpiece can be assembled. According to the preset torque, when the torque of the assembly head 105 twisting the workpiece reaches a predetermined value, the assembly head 105 is set to the shell 10 The solenoid valve at the top of the 3 cuts off the air source, so that the pneumatic assembly component 101 stops outputting torque, and the assembly head 105 stops assembling the workpiece accordingly. When the connecting end 104 rotates, the ring 107 prevents the outer shell 103 from contacting with the connecting end 104 to generate friction and cause damage to the connecting end 104. When the assembly head 105 needs to be replaced after frequent use, the protective frame 106 can be rotated to the left to drive the assembly head 105 to rotate on the connecting end 104, and then the assembly head 105 is removed from the connecting end 104, and then a new assembly head 105 is replaced. By rotating the new assembly head 105 to the right, the protective frame 106 is driven to rotate, and then the new assembly head 105 is fixed on the connecting end 104, which is convenient for the subsequent use of the staff, thereby solving the problem that the existing electronic air cut-off type pneumatic tool adopts the electronic air cut-off method, so that the pneumatic tool can be used for a long time, which causes the tool head of the pneumatic tool to be easily damaged during frequent use, affecting the normal assembly work.

[0029] Among them, the top connecting frame 108 is fixedly connected to the shell 103 and is located on the side of the shell 103 away from the connecting end 104.

The external solenoid valve is connected through the top connecting frame 108, and the output end of the solenoid valve is clamped through the elastic member 109, thereby facilitating the use of the solenoid valve and being able to cut off the gas source.

[0030] Secondly, the rotating shaft 110 is fixedly connected to the shell 103 and is located at one side of the shell 103, the tilting piece 111 is rotatably connected to the rotating shaft 110 and is located at one side of the rotating shaft 110, the spring 112 is fixedly connected to the tilting piece 111 and is fixedly connected to the shell 103 and is located at one side of the tilting piece 111, the hand-holding end 113 is slidably connected to the shell 103 and is located at the side of the shell 103, the staff can hold the hand-holding end 113 when using the assembly tool, and when the hand-holding end 113 is severely worn or accidentally damaged after long-term use and needs to be replaced, the staff can rotate the tilting piece 111 on the rotating shaft 110 so that the side of the tilting piece 111 close to the hand-holding end 113 is tilted up, and the side away from the hand-holding end 113 is pressed down, so as to compress the spring 112, and then the hand-holding end 113 can be tilted out from the shell 103, so that the staff can replace the new hand-holding end 113 conveniently.

[0031] Again, the frame 114 is fixedly connected to the housing 103 and is located on a side of the housing 103 close to the rotating shaft 110. The cover 115 is connected to the sliding portion and is located on one side of the frame 114. When the grip end 113 needs to be replaced, the cover 115 can be slid first to unfold the frame 114, making it convenient for the staff to rotate the lifter 111.

[0032] In addition, the insertion rod 116 is slidably connected to the shell 103 and is located on a side of the shell 103 close to the tilting piece 111. The anti-slip portion 117 is fixedly connected to the insertion rod 116 and is located on the side of the insertion rod 116. When the tilting piece 111 tilts out the anti-slip portion 117, the insertion rod 116 slides out from the shell 103, so that the anti-slip portion 117 is removed from the shell 103, which is convenient for the staff to replace. The staff can align the new anti-slip portion 117 with the shell 103, slide the insertion rod 116 into the shell 103, and fix the anti-slip portion 117 on the shell 103.

The connecting shaft 122 is fixedly connected to the output rod 121 and is connected to the connecting end 10 4 is fixedly connected and located at one side of the output rod 121. By starting the external air source, the air motor 118 is driven to operate, the output shaft 119 is driven to operate, and then the output rod 121 on the coupling 120 is driven to operate, so that the connecting shaft 122 rotates with the rotation, and the connecting end 104 rotates accordingly, driving the assembly head 105 to operate, so that the workpiece can be assembled. When a predetermined torque value is reached, the torque sensor arranged on the output shaft 119 transmits a signal to the external solenoid valve, so that the external solenoid valve can cut off the air source, so that the air motor 118 stops operating.

[0034] The present embodiment is a torque-controllable air-off straight-handle assembly tool. When it is needed, the staff holds the anti-slip portion 117 on the housing 103 and starts the external air source to drive the pneumatic motor 118 to operate, drive the output shaft 119 to operate, and then drive the output rod 121 on the coupling 120 to operate, so that the connecting shaft 122 rotates with the rotation, and the connecting end 104 rotates accordingly, driving the assembly head 105 to operate, so that the workpiece can be assembled and the workpiece can be assembled according to the preset torque. When the torque of the assembly head 105 twisting the workpiece reaches a predetermined value, the air source is cut off by the solenoid valve arranged at the top of the housing 103, so that the pneumatic motor 118 stops running. When the connecting end 104 rotates, the ring 107 is used to prevent the housing 103 from contacting with the connecting end 104 to generate friction and cause damage to the connecting end 104. When the assembly head 105 needs to be replaced after frequent use, the protective frame 106 can be rotated leftward to drive the assembly head 105 at the connecting end 1 04, and then the assembly head 105 is removed from the connecting end 104, and then the new assembly head 105 is replaced. By rotating the new assembly head 105 to the right, the protective frame 106 is driven to rotate, and then the new assembly head 105 is fixed on the connecting end 104, which is convenient for the staff to use later. When the hand-held end 113 is severely worn or accidentally damaged after long-term use and needs to be replaced, the cover plate 115 can be slid first to unfold the frame 114, so that the staff can rotate the tilting piece 111 conveniently, so that the side of the tilting piece 111 close to the hand-held end 113 is tilted up, and the side away from the hand-held end 113 is pressed down to compress the spring 112, so that the hand-held end 113 can be tilted out of the housing 103, which is convenient for the staff to replace the new hand-held end 113, thereby solving the problem that the existing electronic air-off type pneumatic tool adopts the electronic air-off method, so that the pneumatic tool can be used for a long time, which causes the blade of the pneumatic tool to be easily damaged during frequent use, affecting the normal assembly work.
