Description

Technical Field

[0001] This utility model relates to the field of aluminum busbar detection technology, specifically to a positioning structure for aluminum busbar detection. Background Technology

[0002] Copper or aluminum busbars are widely used in electrical equipment, especially in complete power distribution systems, where they serve to transmit current and connect electrical devices in circuits. During the manufacturing process of copper or aluminum busbars, to ensure they meet dimensional accuracy requirements and guarantee finished product quality, they need to be inspected using gauges. This inspection process requires positioning and fixing the aluminum busbars.

[0003] A search revealed a Chinese patent (publication number: CN22035242424U) that discloses "a testing fixture for detecting whether the dimensions of a component to be tested are qualified, wherein the two ends of the component to be tested are respectively provided with a first mounting hole and a second mounting hole, comprising: a base plate, which can be fixed to the operator's work platform; a first positioning component, which is disposed on the base plate and is used to limit and fix the end of the component to be tested having the first mounting hole; and a second positioning element, which includes a second positioning block and a second positioning post movably disposed on the second positioning block, wherein the second positioning block is disposed on the base plate."

[0004] While the above design achieves basic positioning functionality, it relies on pre-set mounting holes for the components and a fixed positioning height for the aluminum busbar. However, in the inspection of irregularly shaped aluminum busbars, the positioning structure needs to be adaptable to changes in height and angle. Existing technologies mostly employ rigid fixing schemes, which cannot quickly adjust the positioning position, thus limiting the versatility and efficiency of the inspection fixture. In view of this, the present invention proposes a positioning structure for aluminum busbar detection. Utility Model Content

[0005] This invention proposes a positioning structure for aluminum busbar detection, which solves the problem that existing technologies cannot adapt to the different heights and angles of irregularly shaped aluminum busbars.

[0006] The technical solution of this utility model is as follows: A positioning structure for aluminum busbar detection includes a base, a support frame fixedly connected to the top of the base, a movable seat slidably connected to the inner side of the support frame, a positioning plate rotatably connected to the top of the movable seat, an assembly seat adapted to the aluminum busbar fixedly connected to the top of the positioning plate, a movable rod movably connected to the inner side of the support frame penetrating the top wall of the support frame, a handwheel fixedly connected to the bottom of the movable rod, a locking member provided on the inner side of the movable seat to restrict the rotation of the positioning plate by cooperating with the vertical sliding of the movable rod, and a lifting member provided on the inner side of the support frame to drive the movable seat to slide vertically by cooperating with the rotation of the movable rod.

[0007] Preferably, the locking component includes a sector-shaped toothed block coaxially fixedly connected to the positioning plate, a slider is fixedly connected to the top of the movable rod, a locking block that meshes with the sector-shaped toothed block is fixedly connected to the top of the slider, and a pressure spring is sleeved on the top of the movable rod, with the two ends of the pressure spring abutting against the top wall of the slider and the support frame, respectively.

[0008] Preferably, the lifting component includes an external threaded sleeve sleeved on the outside of the movable rod, the external threaded sleeve being rotatably connected to the inside of the support frame, the external threaded sleeve penetrating the bottom wall of the movable seat and being threadedly connected to the movable seat, a limit strip being fixedly connected to the outside of the movable rod, and a limit groove being provided on the inner wall of the external threaded sleeve to fit the limit strip with a clearance.

[0009] Preferably, both ends of the inner side of the support frame are fixedly connected to guide rails arranged vertically, and both ends of the movable seat are slidably connected to the corresponding guide rails.

[0010] Preferably, the mounting base is provided with a clamping assembly, which includes two mounting plates, which are respectively fixedly connected to both sides of the mounting base. One of the mounting plates has a pressure plate hinged to its outer side, and a locking block is fixedly connected to one end of the pressure plate. The other mounting plate has a limiting member for fixing the locking block on its outer side.

[0011] Preferably, the limiting member includes a card holder fixedly connected to the outside of the mounting plate, the card holder slidingly engaging with the card block, an insert rod slidably connected to the inner side of the card holder penetrating the inner wall of the card holder, one end of the insert rod being fixedly connected to a limiting block that abuts against the card block, and the other end of the insert rod being fixedly connected to a pull block.

[0012] Preferably, the inner side of the card holder is provided with a clearance groove that slides with the limiting block, and a return spring is sleeved on the inner side of the clearance groove. The two ends of the return spring abut against the inner wall of the limiting block and the clearance groove, respectively.

[0013] The working principle and beneficial effects of this utility model are as follows: 1. The vertical sliding of the movable seat is achieved through the lifting component, thereby flexibly adjusting the height of the positioning plate to adapt to the installation requirements of different positions of irregular aluminum bars; the lifting component adopts the cooperation of external thread sleeve and movable rod to convert rotational motion into linear motion, ensuring smooth and accurate height adjustment; this design overcomes the limitation of fixed positioning height in the existing technology, improves the versatility of the fixture for irregular aluminum bars, reduces the frequency of fixture replacement, and improves inspection efficiency.

[0014] 2. The positioning plate can rotate freely, and its angle can be adjusted and fixed through locking components to meet the positioning requirements of aluminum bars of different shapes. The locking components adopt a fan-shaped toothed block and locking block meshing design to ensure that the positioning plate does not shift during inspection; this design provides adaptive locking capability, is easy to operate, avoids errors caused by manual intervention, and ensures positioning stability during inspection, making it particularly suitable for multi-angle inspection scenarios of irregularly shaped aluminum bars.

[0015] 3. Height and angle adjustments can be controlled simultaneously with a single handwheel operation, simplifying the aluminum busbar inspection process. Users can turn the handwheel to drive the lifting mechanism and pull it to control the locking mechanism, achieving "one-click" adjustment; significantly improving inspection efficiency, reducing operator skill requirements, suitable for batch inspection environments, and in line with industrial automation trends.

[0016] 4. The clamping assembly enables rapid clamping and release of the aluminum busbar, and avoids accidental loosening through mechanical locking, thereby improving testing safety; it simplifies the fixing process, shortens the clamping time, and the return spring ensures automatic reset, preventing the aluminum busbar from shifting during testing and ensuring the accuracy of the results.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figures 1 to 8 As shown, this embodiment proposes a positioning structure for aluminum busbar detection, including a base 21. A support frame 22 is fixedly connected to the top of the base 21. A movable seat 23 is slidably connected to the inner side of the support frame 22. A positioning plate 24 is rotatably connected to the top of the movable seat 23. An assembly seat 25 adapted to the aluminum busbar 10 is fixedly connected to the top of the positioning plate 24. A movable rod 26 penetrating the top wall of the support frame 22 is movably connected to the inner side of the support frame 22. A handwheel 27 is fixedly connected to the bottom of the movable rod 26. A locking member 28 is provided on the inner side of the movable seat 23 to restrict the rotation of the positioning plate 24 by cooperating with the vertical sliding of the movable rod 26. A lifting member 29 is provided on the inner side of the support frame 22 to drive the movable seat 23 to slide vertically by cooperating with the rotation of the movable rod 26.

[0022] In this embodiment, during operation, the user rotates the handwheel 27 to rotate the movable rod 26, which causes the lifting component 29 to drive the movable seat 23 to slide vertically along the inner side of the support frame 22, thereby adjusting the height of the positioning plate 24 to accommodate the different heights of the irregularly shaped aluminum busbar 10. At the same time, by pulling down the handwheel 27, the movable rod 26 slides downward, causing the locking component 28 to disengage from the positioning plate 24, allowing the positioning plate 24 to rotate freely to adjust the installation angle. This can meet the positioning requirements of assembly seats 25 of different shapes, and has strong versatility. This design allows for simultaneous control of height and angle adjustment through a single operation of the handwheel 27, simplifying the aluminum busbar inspection process and improving efficiency.

[0023] In a further preferred embodiment of this utility model, the locking member 28 includes a sector-shaped toothed block 281 coaxially and fixedly connected to the positioning plate 24, a slider 282 fixedly connected to the top of the movable rod 26, a locking block 283 that meshes with the sector-shaped toothed block 281 fixedly connected to the top of the slider 282, and a pressure spring 284 sleeved on the top of the movable rod 26, with the two ends of the pressure spring 284 abutting against the top wall of the slider 282 and the support frame 22 respectively.

[0024] In this embodiment, the locking member 28 includes a locking process and a releasing process during operation, as follows: Locking process: When the movable rod 26 slides upward, the slider 282 rises accordingly. The locking block 283 is tightly engaged with the sector tooth block 281 under the action of the pressure spring 284, thereby restricting the rotation of the positioning plate 24. The pressure spring 284 provides elastic compensation to ensure uniform meshing force and prevent slippage. Release process: When the movable rod 26 slides downward, the pressure spring 284 is compressed, the locking block 283 disengages from the sector tooth block 281, and the positioning plate 24 can rotate freely. The reset action of the pressure spring 284 causes the locking element 28 to automatically return to its original position after operation. The meshing design of the sector tooth block 281 and the locking block 283 provides mechanical interlocking, ensuring that the positioning plate 24 remains fixed during testing and preventing the positioning plate 24 from shifting. The pressure spring 284 makes the locking element 28 self-adaptive, which is easy to operate and reduces manual intervention.

[0025] In a further preferred embodiment of this utility model, the lifting component 29 includes an external threaded sleeve 291 sleeved on the outside of the movable rod 26. The external threaded sleeve 291 is rotatably connected to the inside of the support frame 22. The external threaded sleeve 291 penetrates the bottom wall of the movable seat 23 and is threadedly connected to the movable seat 23. A limit strip 293 is fixedly connected to the outside of the movable rod 26. A limit groove 294 is provided on the inner wall of the external threaded sleeve 291, which is in clearance fit with the limit strip 293. Both ends of the inner side of the support frame 22 are fixedly connected to guide rails 292 arranged vertically. Both ends of the movable seat 23 are slidably connected to the corresponding guide rails 292.

[0026] In this embodiment, rotating the handwheel 27 causes the movable rod 26 to rotate, which in turn drives the limiting strip 293 to rotate. Since the limiting strip 293 and the limiting groove 294 are in clearance fit, this prevents the movable rod 26 from rotating relative to the external threaded sleeve 291 during movement, ensuring stable power transmission. The external threaded sleeve 291 rotates accordingly, and the threaded connection between the external threaded sleeve 291 and the movable seat 23 converts the rotational motion into the vertical linear motion of the movable seat 23, thereby realizing the height adjustment of the positioning plate 24. This adapts to the positioning and installation at different heights of the irregular aluminum strip 10, improving the versatility of the structure. The guide rail 292 guides the movable seat 23 to slide, ensuring smooth movement.

[0027] In a further preferred embodiment of this utility model, a clamping assembly 20 is provided on the assembly base 25. The clamping assembly 20 includes two mounting plates 201, which are respectively fixedly connected to both sides of the assembly base 25. A pressure plate 202 is hinged to the outer side of one mounting plate 201, and a locking block 203 is fixedly connected to one end of the pressure plate 202. A limiting member 204 for fixing the locking block 203 is provided on the outer side of the other mounting plate 201. The limiting member 204 includes a locking seat 2041 fixedly connected to the outer side of the mounting plate 201. The locking seat 2041 and the locking block 203 are connected to each other. The block 203 is slidably engaged, and the inner side of the card holder 2041 is slidably connected to an insert rod 2042 that penetrates the inner wall of the card holder 2041. One end of the insert rod 2042 is fixedly connected to a limiting block 2043 that abuts against the card block 203, and the other end of the insert rod 2042 is fixedly connected to a pull block 2044. The inner side of the card holder 2041 is provided with a clearance groove 2045 that slidably engages with the limiting block 2043. A return spring 2046 is sleeved on the inner side of the clearance groove 2045, and the two ends of the return spring 2046 abut against the inner walls of the limiting block 2043 and the clearance groove 2045, respectively.

[0028] In this embodiment, the clamping assembly 20 can quickly clamp and release the aluminum busbar 10, and the specific operation is as follows: Clamping process: After placing the aluminum strip 10 on the mounting base 25, rotate the pressure plate 202 to cover the aluminum strip 10. The locking block 203 slides into the locking base 2041. When the pulling block 2044 is pulled, the insert rod 2042 drives the limiting block 2043 to compress the return spring 2046 and disengage from the locking block 2043, allowing the pressure plate 202 to adjust its position. After releasing the pulling block 2044, the return spring 2046 pushes the limiting block 2043 to abut against the locking block 203, thus achieving clamping and fixing. Release process: Reverse operation can quickly release aluminum busbar 10, and return spring 2046 ensures that limit component 204 automatically resets; The design of the pressure plate 202 and the limiting component 204 simplifies the fixing and releasing process of the aluminum strip 10 and improves the detection efficiency; the mechanical locking method avoids accidental loosening and ensures detection safety.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
