In addition, due to the fact that the contact area between the clamp and the ascending flanged base is relatively small, abrasion dents are prone to being left on the surface of the ascending flanged base due to the small contact area in the pressure applying process, the appearance quality of the ascending flanged base is affected by the dents, and more importantly, the overall strength of materials can be weakened by the dents. And the yield is further reduced.

[0002] As a kind of key device for changing alternating voltage using electromagnetic induction principle, transformer plays a pivotal role in power system and numerous industrial fields.In the complex structure system of transformer, riser is not only a simple support structure, but also a precision component integrating multiple functions.Riser is one of the main responsibilities to provide stable support and accurate positioning for bushing inside transformer, ensure that bushing keeps stable during operation, prevent any displacement or vibration that may affect electrical performance, and the internal space of riser is also ingeniously arranged with bushing-type current transformer.

[0003] In prior art, as a key component in transformer, riser undertakes important responsibilities of support, installation and protection, so it is crucial to detect it with high precision before leaving factory to ensure that it can play due role in actual use, however, the existing detection positioning device usually adopts the way of clamp fixation to operate, considering that riser surface has tubular structure and itself is a hollow column, when clamp is pressed inward to realize fixation, too tight clamping force will cause riser to twist inward or even collapse, so as to change the shape of its main structure, and further affect its support effect, so that riser cannot be used normally, in addition, since the contact area between clamp and riser is relatively small, in the process of applying pressure, small contact surface is easy to leave wear indentation on riser surface, these indentations not only affect the appearance quality of riser, more importantly, they will weaken the overall strength of material, further reduce yield. UTILITY MODEL CONTENT

[0004] The utility model aims at solving the shortcomings in prior art, and proposes a kind of positioning device for high-precision transformer component detection.

[0006] Preferably, the bottom of the workbench is fixed with a base plate, and a sunken arc groove is formed in the top of the base plate. The inner wall of the sunken arc groove is fixed with a spring arc piece. The peripheral surface of the middle rotary cylinder is fixed with a rotary control disc. The peripheral surface of the rotary control disc is circumferentially provided with an arc inlay groove. In the prior art, the lifting seat is a key component in the transformer, and its surface structure is complex and diverse. When detecting, the staff needs to carefully check each position on the surface to ensure that every detail meets the quality standards. However, it is difficult to detect the position of the lifting seat towards the ground, which brings a great challenge to the staff. In order to accurately detect these hard-to-reach parts, the staff often needs to squat or adopt other inconvenient postures to operate. This not only increases the difficulty of work, but also greatly reduces the work efficiency. Long-time maintenance of such an uncomfortable posture can easily cause the staff to be tired, thereby affecting the user experience of the entire detection process. To solve such problems, the utility model adopts the installation of a rotary control disc. When the staff needs to detect other positions of the component, the staff rotates the rotary control disc, which drives the middle rotary cylinder, the end rotary cylinder, the limit circle and the fixed residual disc to rotate as a whole. Thus, the lifting seat main body rotates with it, which is convenient for the staff to detect. At the same time, when the staff rotates, the spring arc piece is embedded in the corresponding arc inlay groove, so that the equipment remains in position after rotation, preventing it from rotating by itself. This achieves the effects of improving work efficiency and improving user experience.

[0008] Preferably, the other end of the pressure cutting edge column is fixed with a pressure pad, so as to reduce the friction between the two, and improve the service life of the equipment.

[0009] Preferably, the surface of the rotary control disc is provided with a weight reduction disc groove, so as to reduce the self-weight of the equipment and reduce the production cost of the equipment.

[0010] Preferably, the one side of the pad substrate is provided with an anti-inclined slope, so as to prevent foreign matter or personnel from staying during the operation of the equipment, and improve the production safety.

[0028] The fixed residual disc 209 is provided with a sink pad ring groove 502 at one end, and a buffer ring pad 5 is glued and fixed to the inner wall of the sink pad ring groove 502. In the process of tightly fitting the transformer lifting seat main body 1 and the fixed residual disc 209, because both of them are made of rigid materials, the direct rigid contact under the extrusion easily leads to local stress concentration. Once the applied force exceeds the bearing limit of the material, plastic deformation or micro-cracks and other problems are caused. Such structural damage not only affects the overall stability and service life of the lifting seat, but also causes functional failure in subsequent use. More seriously, the deformation caused in the assembly process directly affects the yield of the product, so that the originally qualified products are judged as unqualified products due to insufficient assembly accuracy. The installation of the buffer ring pad 5 solves the problem, realizes the buffer of the sink pad ring groove 502 to prevent the extrusion damage between the components when the components are extruded, increases the friction between the contact surfaces of the two, improves the fixing effect, and improves the yield.

[0029] The working principle of the utility model is: when the staff needs to detect the lifting seat component of the transformer, the lifting seat main body 1 is sleeved into the half solid inner circle 2010 and tightly fixed to the fixed residual disc 209, then the eccentric wheel 203 is rotated to one side by pressing the pressure rod 204 to extrude the pressure cutting edge column 205 to make the transmission rod 208 forward, the half circle insert 2013 in the I-shaped groove 2011 is pushed by the transmission rod 208 and rotates outwardly with the shaft 2012 as the axis, and the beak pressure piece 2015 tightly presses the bottom inner buckle edge of the lifting seat main body 1 and is fixed by pressure. Because the pressure part is not located on the structure surface of the lifting seat main body 1 and does not damage the main body structure, the influence is very small. When the staff needs to detect other positions of the component, the staff rotates the rotary control disc 404 to drive the middle rotary cylinder 2, the end rotary cylinder 201, the limiting circle 202 and the fixed residual disc 209 to rotate as a whole. Thus the lifting seat main body 1 rotates with it, which is convenient for the staff to detect. At the same time, when the staff rotates, the spring arc piece 401 is embedded in the corresponding arc embedding groove 403, so that the equipment maintains the position after rotation and prevents self-rotation. When the components are extruded, the sink pad ring groove 502 buffers to prevent the extrusion damage between the components, and increases the friction between the contact surfaces of the two to improve the fixing effect.
