Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a novel tooling fixture. Background Technology

[0002] As a key component of the automotive powertrain, the performance and reliability of the automotive motor directly affect the overall operation of the vehicle. The busbar connector on the automotive motor terminal block plays a crucial role in the motor, responsible for reliably connecting the various internal components and external circuits, ensuring stable and efficient current transmission, and thus guaranteeing the normal operation of the motor. Busbar connectors typically consist of multiple copper busbars and an insulating injection-molded material surrounding them. As the core component for current conduction, the installation position and precision of the copper busbars have a decisive impact on the electrical performance and mechanical stability of the busbar connector.

[0003] In the current production process of automotive motor terminal block bus connectors, when fixing multiple copper busbars in the mold for injection molding, the main method relies on manual placement of the copper busbars one by one. This operation requires operators to spend a lot of time picking up, positioning, and placing the copper busbars. The placement of each copper busbar needs to be precisely aligned with the corresponding position in the mold, resulting in a long time-consuming positioning and fixing process before injection molding, which seriously restricts production efficiency.

[0004] Furthermore, when manually placing busbars, it is difficult to guarantee that each busbar will be accurately positioned within the mold due to factors such as operator skill level, fatigue, and visual judgment errors. Different operators, and even the same operator at different times, can cause deviations in busbar placement. This instability in positioning accuracy directly affects the quality of the busbar connector. For example, it may cause the spacing between busbars to fail to meet design requirements, thus affecting electrical insulation performance; or it may cause misalignment between the busbars and the injection mold, resulting in defects such as burrs and deformation in the molded product, increasing the reject rate and raising production costs. Utility Model Content

[0034] 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.

[0035] like Figure 1-7 As shown, this utility model provides a novel tooling fixture, which is mainly used to fix multiple busbar copper busbars 15 and push them into the mold 17 that needs to be injection molded at one time, so as to finally form the busbar connector of the automotive motor terminal board.

[0036] The fixture consists of a fixed plate 1, a movable plate 2, and related components between them. The fixed plate 1 and the movable plate 2 are arranged in parallel, and the movable plate 2 can reciprocate toward the fixed plate 1 within a certain range.

[0037] Regarding the fixed plate 1, on the side of the fixed plate 1 facing away from the movable plate 2, multiple positioning pieces 3, positioning rods 4, outer limiting blocks 5, and inner limiting blocks 6 are respectively arranged circumferentially. The outer limiting blocks 5 are distributed around the periphery of the positioning pieces 3, and the inner limiting blocks 6 are distributed inside the positioning pieces 3. The positioning rods 4 are fixed to the middle of the positioning pieces 3 and protrude upwards, used for preliminary positioning of the copper busbar and determining the installation position of the copper busbar. The outer limiting blocks 5 have outer limiting grooves 501, and the inner limiting blocks 6 have inner limiting grooves 601. The copper busbar can be embedded and installed in these limiting grooves to further ensure the positioning accuracy of the copper busbar.

[0038] The fixing plate 1 is provided with a positioning rod mounting hole 102, an outer limit block mounting hole 103, and an inner limit block mounting hole 104, which are used to install and fix the positioning rod 4, the outer limit block 5, and the inner limit block 6, respectively. One end of the positioning rod 4 is provided with a positioning rod limiting part 401 that is fixed in the positioning rod mounting hole 102, which ensures that the positioning rod 4 is firmly installed and will not loosen or shift during use; one end of the outer limit block 5 is provided with an outer limit block limiting part 502 that is fixed in the outer limit block mounting hole 103, which ensures the installation stability of the outer limit block 5; one end of the inner limit block 6 is provided with an inner limit block limiting part 603 that is fixed in the inner limit block mounting hole 104, which also serves to fix the inner limit block 6.

[0039] One side of the fixing plate 1 is provided with an inner cover plate 10 that simultaneously covers all the positioning rod mounting holes 102, the outer limit block mounting holes 103, and the inner limit block mounting holes 104. The function of the inner cover plate 10 is to fix and protect the components inside the mounting holes, prevent dust, debris, etc. from entering the mounting holes and affecting the normal operation of the components, and at the same time make the appearance of the tooling fixture more neat.

[0040] Regarding the movable plate 2, the side of the movable plate 2 facing the fixed plate 1 is provided with multiple intermediate ejector rods 7, outer ejector rods 8, and inner ejector rods 9. One end of the intermediate ejector rod 7 pushes the copper busbar upward through the intermediate hole 301 in the middle of the positioning piece 3. The number of outer ejector rods 8 corresponds to the number of outer limit blocks 5, and they are distributed around the periphery of the corresponding outer limit blocks 5. The outer ejector rods 8 push the copper busbar upward through the outer hole 101 in the fixed plate 1. The number and position of the inner ejector rods 9 correspond to the inner limit blocks 6, and one end of them pushes the copper busbar upward through the inner hole 602 in the middle of the inner limit groove 601. This arrangement of multiple ejector rods ensures that the copper busbar is subjected to uniform force during the ejection process, avoiding deformation or damage to the copper busbar due to excessive local force.

[0041] The movable plate 2 is provided with a middle ejector rod mounting hole 201, an outer ejector rod mounting hole 202, and an inner ejector rod mounting hole 203, which are used to install and fix the middle ejector rod 7, the outer ejector rod 8, and the inner ejector rod 9, respectively. One end of the middle ejector rod 7 is provided with a middle ejector rod limiting part 701 that is limited and fixed in the middle ejector rod mounting hole 201 to ensure that the middle ejector rod 7 is firmly installed; one end of the outer ejector rod 8 is provided with an outer ejector rod limiting part 801 that is limited and fixed in the outer ejector rod mounting hole 202 to ensure the stability of the outer ejector rod 8; one end of the inner ejector rod 9 is provided with an inner ejector rod limiting part 901 that is limited and fixed in the inner ejector rod mounting hole 203 to enable the inner ejector rod 9 to work normally.

[0042] One side of the movable plate 2 is provided with an outer cover plate 11 that simultaneously covers all the intermediate ejector rod mounting holes 201, the outer ejector rod mounting holes 202, and the inner ejector rod mounting holes 203. The outer cover plate 11 has a similar function to the inner cover plate 10, mainly to fix and protect the mounting holes and ejector rods on the movable plate 2, prevent external factors from damaging the components, and improve the overall appearance quality of the tooling fixture.

[0043] To facilitate user operation, several hand-held blocks 12 are arranged parallel to each other on the side of the movable plate 2 away from the fixed plate 1. The hand-held blocks 12 are fixedly connected to the fixed plate 1 by several guide posts 13. The movable plate 2 is sleeved on the outside of the guide posts 13 and can move stably under the guidance of the guide posts 13. After multiple busbar copper busbars 15 are fixed at the same time, the user can quickly position the tooling fixture and mold 17 through the hand-held blocks 12, and then push the multiple busbar copper busbars 15 into the mold 17 by pressing the movable plate 2.

[0044] A number of spring members 14 are provided between the fixed plate 1 and the movable plate 2 for resetting the position of the movable plate 2. When the movable plate 2 needs to be reset, it is reset by the elastic force of the spring members 14. Spring mounting grooves 121 for installing the spring members 14 are provided at the corresponding positions of the fixed plate 1 and the movable plate 2.

[0045] In use, for example, if six busbar copper busbars 15 need to be pushed into the mold 17 at once, three busbar copper busbars 15 are installed together with two copper busbar patches 16 in the tooling fixture. At this time, the two sets of structures form a reverse symmetrical structure. During installation, the copper busbar patches 16 are first positioned on the positioning piece 3 and fixed by the positioning rod 4. At this time, the three extension ends of the copper busbar patches 16 are fixed by the outer limiting groove 601. Three busbar copper busbars 15 are installed between two copper busbar patches 16 in sequence and are built together with the two copper busbar patches 16. When installing the busbar copper busbars 15, each busbar copper busbar 15 is positioned above the copper busbar patches 16, and the middle of the busbar copper busbar 15 is fixed by an inner limiting groove 601. At this time, the two extension ends of the busbar copper busbar 15 are fixed by the outer limiting groove 601. Both the extended ends of the copper busbar patch 16 and the extended ends of the busbar copper busbar 15 are aligned with the outer ejector rod 8 after extension for easy ejection. When the tooling fixture is aligned with the corresponding injection groove of the mold 17, the movable plate 2 is pressed, and all the copper busbar patches 16 and busbar copper busbars 15 are simultaneously pushed into the corresponding groove of the mold 17 by the middle ejector rod 7, the outer ejector rod 8 and the inner ejector rod 9.

[0046] Compared with traditional technologies, the tooling fixture provided by this technical solution can fix multiple busbar copper busbars 15 at one time, and then move the multiple busbar copper busbars 15 into the mold for positioning and injection molding at one time. It eliminates the need to install each busbar copper busbar 15 into the mold individually, reducing the difficulty of installing the busbar copper busbars 15 into the mold, effectively improving the accuracy of the busbar copper sheet position and increasing work efficiency.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
