Description

Technical Field

[0001] This utility model relates to the field of adhesive application tooling technology, specifically to an adhesive application tooling for the terminal block of a rotary transformer. Background Technology

[0002] The protective cover of the rotary transformer contains wires. After the wires are connected, in order to prevent foreign objects from entering, glue is usually injected onto the surface of the wires before the protective cover is installed to seal the upper surface of the rotary transformer.

[0003] Existing glue application methods typically involve manual application, followed by scraping off excess glue from the surface of the rotary transformer using a scraper. This manual application method suffers from inconsistent quality and low efficiency. Therefore, a glue application fixture for rotary transformers was designed. Utility Model Content

[0004] The purpose of this utility model is to provide a glue-applying fixture for the terminal block of a rotary transformer. The glue-applying plate positions the two sides of the glue-applying part of the rotary transformer and fixes the glue-applying part on the top block. Then, the glue is filled by the glue-applying pump. After the glue is filled, pressure is generated to clamp the glue-applying part between the glue-applying plate and the top block, thus completing the setting of the glue.

[0005] This utility model provides the following technical solution: a glue-applying fixture for the terminal block of a rotary transformer, comprising a top plate and a bottom plate fixed on a column, the upper end of which is fixed with a downward pressing cylinder, the output end of which passes through the top plate and extends and retracts below the top plate, the output end of which is connected to a glue-applying pressure plate, the glue-applying pressure plate comprising an upper cover plate, side plates, and side baffles, the upper cover plate being connected to the downward pressing cylinder, the side plates being formed on opposite sides of the upper cover plate, the side baffles being formed on one side of the upper cover plate and located between the two side plates, the upper cover plate being located above the glue-applying part of the rotary transformer, the side plates being located on both sides of the glue-applying part of the rotary transformer, and the side baffles being located on the outer side of the glue-applying part of the rotary transformer to block the glue, the upper cover plate having a glue-applying port, and a glue-applying pump being fixed on the top plate, the glue-applying pump being connected to the glue-applying port via a pipe.

[0006] According to the above technical solution, the bottom surface of the side plate is flush with the lower surface of the glue injection part of the rotary transformer, so that there is a gap between the glue injection part and the upper cover plate, which makes it convenient to adjust the glue injection thickness using glue injection pressure plates of different specifications.

[0007] According to the above technical solution, a connecting plate is fixed on the upper surface of the upper cover plate. The connecting plate is connected to the output end of the lower cylinder by screws. The connection between the connecting plate and the lower cylinder avoids unevenness on the inner wall of the upper cover plate and improves the quality of the adhesive layer surface.

[0008] According to the above technical solution, a lifting cylinder is fixed at the lower end of the base plate. The output end of the lifting cylinder passes through the base plate and extends and retracts above the base plate. A top block is connected to the output end of the lifting cylinder. The top block is used to apply pressure to the lower surface of the glue injection part of the rotary transformer. By setting the top block, the clamping position of the glue injection part is raised, the stroke of the pressing cylinder is reduced, and the model requirements and equipment costs of the pressing cylinder are reduced.

[0009] According to the above technical solution, one side of the top block is attached to the end face of the rotary transformer, and the other side of the top block is flush with the outer surface of the side baffle. When applying glue, the bottom surface of the side plate is located on the top block. The support of the side plate by the top block ensures the gap between the upper cover plate and the glue injection part and controls the thickness of the glue injection.

[0010] According to the above technical solution, a cooling channel is provided on the upper part of the top block near the top surface. The lower end of the cooling channel is connected to a water inlet and a water outlet. The water inlet is used to connect to a water pump, and the water outlet is used to connect to a water source.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] (1) The glue injection plate is used to position the glue injection part on both sides of the rotary transformer and fix the glue injection part on the top block. Then the glue is filled by the glue injection pump. After the glue is filled, pressure will be generated to clamp the glue injection part between the glue injection plate and the top block, thus completing the shaping of the glue and improving the surface quality and glue injection efficiency of the glue.

[0013] (2) By opening a cooling channel in the upper part of the top block, the cooling channel is used to accelerate the cooling of the glue, improve the curing efficiency, reduce the clamping time of the rotary transformer, and improve the glue application efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a glue-applying fixture for the terminal block of a rotary transformer, comprising a top plate 1 and a bottom plate 2 fixed on a column 6. A downward pressing cylinder 12 is fixed to the upper end of the top plate 1. The output end of the downward pressing cylinder 12 passes through the top plate 1 and extends and retracts below the top plate 1. The output end of the downward pressing cylinder 12 is connected to a glue-applying pressure plate 3. The glue-applying pressure plate 3 positions the glue-applying part 51 of the rotary transformer 5. The glue-applying pressure plate 3 includes an upper cover plate 31, side plates 32, and side baffles 33. The upper cover plate 31 is connected to the downward pressing cylinder 12. The side plates 32 are formed on opposite sides of the upper cover plate 31. The side baffles 33 are formed on one side of the upper cover plate 31 and are located between the two side plates 32. The upper cover plate 31 is located on the upper side of the glue-applying part 51 of the rotary transformer 5. Side plates 32 are located on both sides of the glue injection section 51 of the rotary transformer 5, limiting the two sides of the glue injection section 51. Side baffles 33 are located on the outer side of the glue injection section 51 of the rotary transformer 5, blocking the glue and preventing the glue from flowing out from the side of the glue injection section 51. The top cover plate 31 has a glue injection port 34. The top plate 1 is also fixed with a glue injection pump 11. The glue injection pump 11 is connected to the glue injection port 34 through a pipe. The glue injection pump 11 injects the glue from the glue injection port 34 into the glue injection section 51 of the rotary transformer 5. The top cover plate 31 and the side baffles 33 also block the upper and side surfaces of the glue injection section 51 and shape the glue, completing the filling of the glue injection section 51 with glue. After the glue cures, the rotary transformer 5 is removed.

[0023] The bottom surface of the side plate 32 is flush with the lower surface of the glue injection part 51 of the rotary transformer 5. The height of the side plate 32 can be selected according to different models as needed, thereby adjusting the glue thickness on the glue injection part 51 to meet the requirements. In this way, there is a gap between the top cover plate 31 and the glue injection part 51, and the rotary transformer 5 needs to be manually supported to prevent the rotary transformer 5 from slipping. After the glue is filled, the pressure generated by the glue will exert a downward pressure on the glue injection part 51 to ensure that the glue injection part 51 is level.

[0024] like Figure 1 As shown, a connecting plate 35 is fixed on the upper surface of the upper cover plate 31. The connecting plate 35 is connected to the output end of the lower pressure cylinder 12 by screws. The connection between the connecting plate 35 and the lower pressure cylinder 12 avoids fasteners on the inner wall of the upper cover plate 31, thereby ensuring the smoothness of the inner wall of the upper cover plate 31 and further ensuring the smoothness of the glue injection surface.

[0025] A lifting cylinder 21 is fixed at the lower end of the base plate 2. The output end of the lifting cylinder 21 passes through the base plate 2 and extends and retracts above the base plate 2. The output end of the lifting cylinder 21 is connected to a top block 4. The top block 4 is used to apply pressure to the lower surface of the glue injection part 51 of the rotary transformer 5. The clamping position of the glue injection part 51 is raised by the top block 4, thereby reducing the stroke of the pressing cylinder 12 and reducing the model requirements.

[0026] One side of the top block 4 is attached to the end face of the rotary transformer 5, and the other side of the top block 4 is flush with the outer surface of the side baffle 33. This increases the contact area between the top block 4 and the glue injection part 51, ensuring the pressure applied by the top block 4 to the glue injection part 51. When applying glue, the bottom surface of the side plate 32 is located on the top block 4, and the top block 4 can support the side plate 32, ensuring the thickness of the glue application.

[0027] like Figure 4 and 5 As shown, a cooling channel 43 is provided on the upper part of the top block 4 near the top surface. The cooling channel 43 cools the glue and accelerates the curing of the glue. The lower end of the cooling channel 43 is connected to a water inlet 41 and a water outlet 42. The water inlet 41 is used to connect to a water pump, and the water outlet 42 is used to connect to a water source.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
