[0002] The electronic expansion valve mainly includes a valve body and a coil. The valve body is equivalent to the rotor of a stepper motor, and the coil is equivalent to the stator of a stepper motor. By applying a pulse drive signal to the coil winding, a regular magnetic field is generated on the pole claws of the coil magnet, which drives the rotation of the rotor inside the valve body, thereby adjusting the flow at the valve port of the valve body and realizing the control of the refrigerant flow in the system. Figure 5 As shown, the electronic expansion valve coil includes a coil body 17 and a connecting clamp ring 18 arranged at the upper end of the coil body 17.

[0016] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.

[0017] The embodiment of the utility model relates to a semi-automatic correction tool for an electronic expansion valve coil, such as Figure 1-5 As shown, it includes a tooling base plate 1, a coil mounting seat 2 is installed on the upper end of the tooling base plate 1, and a coil mounting groove 16 is opened on the upper end of the coil mounting seat 2. A clamping device 12 is installed on the left side of the upper end of the tooling base plate 1, and a correction support 3 is installed on the right side of the upper end of the coil mounting seat 2. A guide sleeve 4 is installed on the left side of the upper end of the correction support 3, and an L-shaped wrench 5 is rotatably installed on the right side. A handle portion 7 is provided on the upper end of the L-shaped wrench 5, and a transversely sliding power rod 8 is installed in the guide sleeve 4. A connecting plate 6 is rotatably installed on the right end of the power rod 8, and one end of the connecting plate 6 is rotatably connected to the corner of the L-shaped wrench 5. An adjusting screw 10 is axially screwed on the left end of the power rod 8, and a positioning nut 11 is screwed on the adjusting screw 10. The positioning nut 11 rests on the right end of the power rod 8, and a correction portion 15 is provided on the right end of the adjusting screw 10.

[0018] The left end of the power rod 8 is axially provided with a long threaded hole, and the right end of the adjusting screw 10 is screwed into the long threaded hole.

[0019] During correction, first place the coil body 17 into the coil mounting groove 16 at the upper end of the coil mounting seat 2, and limit the coil body 17 through the inner wall of the coil mounting groove 16, then start the clamping device 12 to clamp and fix the upper end of the coil body 17, and then turn the L-shaped wrench 5 by hand, and the left end surface of the correction part 15 pushes the connecting clamp ring 18 to the specified position, and the correction work is completed. Figure 2 As shown, at this time, the correction part 15, the adjusting screw 10 and the power rod 8 move to the farthest position to the left; due to long-term use, the position of the correction part 15 may deviate. Just loosen the positioning nut 11, then rotate the adjusting screw 10, adjust the length of the adjusting screw 10 extending outside the power rod 8, and after the adjustment is appropriate, tighten the positioning nut 11 so that the positioning nut 11 rests on the right end of the power rod 8, so that the adjusting screw 10 cannot rotate, and the operation is very convenient.

[0020] A supporting bracket 9 is vertically installed at the upper end of the tooling base plate 1 between the coil mounting seat 2 and the guide sleeve 4. A through hole is opened on the upper part of the supporting bracket 9, and the power rod 8 slides laterally along the inner wall of the through hole; the supporting bracket 9 is provided to assist in supporting the power rod 8 to ensure the stability of the lateral movement of the power rod 8.

[0021] The clamping device 12 is a vertical quick clamp, and an n-shaped pressing block 13 is installed at the clamping end of the vertical quick clamp. The quick clamp is a new type of manual clamp that can accurately position and quickly clamp. The vertical quick clamp is a common type of quick clamp. The vertical quick clamp is an existing component and can be directly purchased on the market. The vertical quick clamp controls the pressing block 13 to press down the upper end of the coil body 17.

[0022] Four positioning grooves 14 are provided on the tooling base plate 1, and the clamping device 12, coil mounting seat 2, supporting bracket 9 and correction support 3 are respectively installed in the corresponding positioning grooves 14 and fixedly connected by fasteners; the positioning grooves 14 are provided to facilitate the rapid positioning of the clamping device 12, coil mounting seat 2, supporting bracket 9 and correction support 3, and then the fasteners are connected and fixed from bottom to top, which is convenient for maintenance and replacement; the fasteners are ordinary long screws.

[0023] The correction part 15 is an external hexagonal nut, which is integrally formed with the adjusting screw 10. By turning the external hexagonal nut with a wrench, the length of the adjusting screw 10 extending outside the power rod 8 can be adjusted; the shape of the external hexagonal nut facilitates the rotation of the adjusting screw 10.

[0024] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0025] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0026] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0027] The above is a detailed introduction to a semi-automatic correction tool for an electronic expansion valve coil provided by the present application. This article uses specific examples to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for general technical personnel in this field, based on the ideas of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
