Abstract
Description
Technical Field
[0001] This utility model belongs to the field of current sensor technology, specifically, it relates to a positioning and installation fixture for a CSU current sensor. Background Technology
[0002] Heating current boxes are widely used in the production process; however, their extremely limited internal space poses a significant challenge to assembly work. Specifically, the installation and assembly of the CSU current sensor and the adapter copper component must be completed inside the heating current box. Due to the confined space, it is difficult for operators to perform the installation operations within it, making the installation of the CSU current sensor and adapter copper component a major challenge. Utility Model Content
[0003] To address the aforementioned problems in the prior art, this utility model provides a CSU current sensor positioning and installation fixture.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: As one aspect of this utility model, a positioning and installation fixture for a CSU current sensor is proposed, comprising: a fixture base plate, wherein a first support plate is provided at the bottom of the fixture base plate. The tooling base plate has a left limiting block on the left side and a right limiting plate on the right side; the first support plate, the left limiting block, the right limiting plate and the tooling base plate form a placement space for accommodating the CSU current sensor. There is a preset distance between the upper surface of the left limiting block and the top surface of the tooling base plate; the upper left part of the tooling base plate is recessed to form a left clearance part, and the left clearance part and the left limiting block form an installation space for the first adapter copper part. The right limiting plate is provided with a right mounting platform, which is used for the installation of the second adapter copper component; A positioning bolt is installed on the left side.
[0005] Furthermore, the first support plate is perpendicular to the tooling base plate.
[0006] Furthermore, the left limiting block is perpendicular to the tooling base plate, and the right limiting plate is perpendicular to the tooling base plate.
[0007] Furthermore, the upper surface of the right mounting platform is higher than the upper surface of the left limiting block.
[0008] Furthermore, there is a preset interval between the left limiting block and the tooling base plate, and there is a preset interval between the right limiting plate and the tooling base plate.
[0009] Furthermore, the centerline of the positioning bolt is perpendicular to the surface of the tooling base plate.
[0010] Furthermore, a silicone sleeve is fitted onto the positioning bolt.
[0011] The CSU current sensor positioning and installation fixture of this utility model has the following advantages: The CSU current sensor, the first adapter copper piece, and the second adapter copper piece are placed together in their corresponding positions on the fixture. After the components are positioned, the locking bolts between the first and second adapter copper pieces and the CSU current sensor are tightened. The clockwise torque during the tightening process determines the position of the first and second adapter copper pieces relative to the CSU current sensor. The first adapter copper piece and the positioning bolt are positioned, and the silicone sleeve effectively prevents the positioning bolt from scratching the adapter copper piece. The second adapter copper piece contacts the right limit plate to complete its positioning, thus meeting the assembly and installation positioning requirements. Attached Figure Description

Detailed Implementation
[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0015] One embodiment of this application provides a CSU current sensor positioning and mounting fixture, such as... Figures 1-2 As shown, it includes: a tooling base plate 1, and a first support plate 2 is provided at the bottom of the tooling base plate 1, the first support plate 2 being perpendicular to the tooling base plate 1; A left limiting block 4 is provided on the left side of the tooling base plate 1, and a right limiting plate 5 is provided on the right side of the tooling base plate 1. The left limiting block 4 is perpendicular to the tooling base plate 1, and the right limiting plate 5 is perpendicular to the tooling base plate 1. A placement space for accommodating the CSU current sensor 3 is formed between the first support plate 2, the left limiting block 4, the right limiting plate 5, and the tooling base plate 1. It should be noted that the structure of the CSU current sensor 3 is existing known technology and will not be described in detail. The focus of this application is: how to limit the CSU current sensor 3. There is a preset distance between the upper surface of the left limiting block 4 and the top surface of the tooling base plate 1; the upper left part of the tooling base plate 1 is recessed to form a left clearance part 11, and the left clearance part 11 and the left limiting block 4 form an installation space for the first adapter copper part 6. The right limiting plate 5 has a right mounting platform 51, the upper surface of which is higher than the upper surface of the left limiting block 4; the right mounting platform 51 is used for the installation of the second adapter copper part 7; it should be noted that the structure of the first adapter copper part 6 and the second adapter copper part 7 is existing known technology and will not be described in detail. The focus of this application is: how to limit the first adapter copper part 6, the second adapter copper part 7 and the CSU current sensor 3 so that the three are installed as one unit.
[0016] In one embodiment, there is a preset interval between the left limiting block 4 and the tooling base plate 1, and there is a preset interval between the right limiting plate 5 and the tooling base plate 1. Under the premise of ensuring full functionality, the preset interval can reduce weight and also facilitate the appropriate adjustment of the CSU current sensor 3 in the placement space from the bottom of the tooling base plate 1.
[0017] In one embodiment, such as Figures 1-2 As shown, a positioning bolt 8 is installed on the left clearance part 11. The center line of the positioning bolt 8 is perpendicular to the surface of the tooling base plate 1. The positioning bolt 8 provides auxiliary positioning for the first adapter copper part 6. A silicone sleeve 9 is provided on the positioning bolt 8 to prevent the positioning bolt 8 from scratching the first adapter copper part 6.
[0018] When using, such as Figures 3-4 As shown, the CSU current sensor 3, the first adapter copper part 6, and the second adapter copper part 7 are placed together in the corresponding positions of the tooling. After the components are positioned, the locking bolts between the first adapter copper part 6, the second adapter copper part 7, and the CSU current sensor 3 are tightened. The position of the first adapter copper part 6 and the second adapter copper part 7 relative to the CSU current sensor 3 is determined by using the clockwise torque during the installation and tightening process. The first adapter copper part 6 and the positioning bolt 8 are positioned. The silicone sleeve 9 effectively prevents the positioning bolt 8 from scratching the first adapter copper part 6. The second adapter copper part 7 contacts the right limit plate 5 to complete the positioning, thereby meeting the assembly and installation positioning requirements.
[0019] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.
[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
