[0022] To make the objectives, contents and advantages of the present invention clearer, the following further describes in detail the specific embodiments of the present invention with reference to the accompanying drawings and embodiments.
[0023] This embodiment provides a controller threaded snap joint installation tool, and its overall structure is as shown in Figure 1 , 2a and Figure 2b, including a handle 101, an auxiliary angle disk 102, an arc handle 103, a guide post 104, a fixed ball 105, a fixed pin 106, a belt buckle 107 and a belt 108.
[0024] The fixed ball 105 is welded to the front end of the arc handle 103, the handle 101 is welded to the rear end of the arc handle 103, and a groove is machined in the middle of the end of the handle 101. An arc groove is machined on the auxiliary angle disk 102. After the fixed post 104 is inserted into the arc groove, the upper and lower ends of the fixed post 104 are welded in the groove at the end of the handle 101. The handle 101 can move in the arc groove of the auxiliary angle disk 102 through the fixed post 104, and realizes the sliding connection between the auxiliary angle disk 102 and the handle 101.
[0025] An installation hole is machined on the front end of the arc handle 103 on the side close to the fixed ball 105. The belt buckle 107 is fixed in the installation hole through the fixed pin 106. The belt 108 passes through the belt buckle 107 and is adhesively fixed to itself.
[0026] The length of the belt 108 is adjustable. The inner arc diameter of the arc handle 103 is designed according to the size of the controller threaded snap joint to be installed, and the diameter of the fixed ball 105 is designed according to the radius of the inner groove on the controller snap joint.
[0027] The usage method of the controller threaded snap joint installation tool of the present invention is as follows:
[0028] Install the controller threaded snap joint installation tool from top to bottom to avoid the cable and install it at the controller threaded snap joint. At this time, the fixed ball 105 is located at the groove of the controller threaded snap joint, so that the handle 101 abuts against the other side of the controller threaded snap joint, and rotate and tighten the controller threaded snap joint. For controller threaded snap joints with different diameters, pass the belt 108 through the joint and the belt buckle 107 and use the friction force to tighten. The auxiliary angle disk 102 is used to measure the tightening angle during the tightening process.
[0029] As shown inFigure 3 and 4 As shown in 4 , the installation process of the threaded snap fasteners for the U, V, and W three-phase AC cables of a certain model generator controller is as follows:
[0030] 1. Select a suitable installation tool 1 for the controller threaded snap fastener joint according to the size of the threaded snap fastener joint to be tightened on the motor controller 2, mainly ensuring that the inner diameter of the arc-shaped handle of the controller threaded snap fastener joint installation tool 1 is greater than or close to the diameter of the controller threaded snap fastener joint 2;
[0031] 2. First, tighten the threaded snap fastener joint of the motor controller 2 by hand to the maximum force;
[0032] 3. Slip the controller threaded snap fastener joint installation tool 1 over the joint to be tightened from top to bottom. At this time, the fixed ball 105 is located in the groove of the threaded snap fastener joint of the motor controller 2. Check whether the other handle 101 can hold against the joint. If it can, tighten it directly. If there is a gap, wrap the belt 108 around the joint and pass it through the belt buckle 107 again to ensure a tight fit without looseness, and then apply force in the tightening direction to continue tightening;
[0033] 4. Use the auxiliary angle scale 102 to measure the tightening angle during the tightening process. Keep the auxiliary angle scale 102 stationary during tightening. Record the position of the handle 101 on the angle scale before tightening. During tightening, the handle 101 moves relative to the arc-shaped groove of the auxiliary angle scale 102 along the guide post 104. Record the angle marked by the handle 101 on the auxiliary angle scale 102 after tightening. Subtract the angle after tightening from the angle before tightening to obtain the actual angle value of this tightening.
[0034] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
