Description

Technical Field

[0001] This utility model relates to the field of pressure plate processing technology, and in particular to a pressure plate assembly positioning structure that prevents displacement. Background Technology

[0002] Pressure plates are elastic metal components, usually made of materials such as phosphor bronze, stainless steel or beryllium copper. They are formed by mechanical stamping or precision machining and are commonly used in low-voltage electrical appliances (circuit breakers, contactors, relays). In circuit breakers, pressure plates press the moving and stationary contacts together to ensure normal conductivity.

[0003] In the production of pressure tablets, clamping tools are needed to fix them. Existing technology discloses a fixing structure for pressure tablet processing, including a worktable and two sets of baffles. The worktable is located between the two sets of baffles, which can rotate in a vertical plane. During fixing, the pressure tablet is placed on the top surface of the worktable, and the two sets of baffles rotate in a vertical plane until they abut against both sides of the pressure tablet, thus clamping and fixing it. However, this fixing structure still has the following problems in actual use:

[0004] When the pressure plate is placed on the worktable, its position in the horizontal plane is prone to shift to the left or right, resulting in inaccurate positioning. When the two sets of baffles clamp the pressure plate on both sides, the pressure plate may shift upward under the push of the baffles, affecting the subsequent fixing effect. Utility Model Content

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a pressure plate assembly positioning structure that prevents displacement, thereby achieving more accurate positioning and avoiding displacement of the pressure plate to the left, right, or upward.

[0006] This utility model provides a...

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] The placement platform of this utility model has a placement groove on its top surface, and a positioning post is provided in the placement groove. During positioning, the bottom of the pressure plate is inserted into the placement groove, so that the positioning hole on the pressure plate is inserted into the positioning post. Then, the top of the positioning plate is pressed and positioned by the pressing block on the positioning component. The positioning post can quickly position the pressure plate and prevent the pressure plate from shifting to the left or right. The placement groove can restrict the pressure plate and prevent the pressure plate from rotating around the positioning post. The pressing block can limit the top of the positioning plate and prevent the positioning plate from shifting upward, thereby improving the positioning and fixing effect of the positioning plate.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0026] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Please refer to Figures 1-6 This utility model provides a pressure plate assembly positioning structure to prevent displacement. The pressure plate includes an integrally formed base plate and an inclined plate. Inclined plates are symmetrically arranged at both ends of the base plate. Positioning holes are provided on the base plate. The pressure plate assembly positioning structure is used to position and fix the pressure plate, including:

[0028] The placement platform 1 has a placement groove 11 on its top surface. A positioning column 12 is fixedly installed in the placement groove 11 along the vertical direction for positioning the pressure plate.

[0029] The positioning component 2 includes a first support 21, a second support 22, a connecting plate 23, and a pressing block 24. The first support 21 and the second support 22 are symmetrically arranged on the top surface of the placement platform 1 about the placement groove 11. One end of the connecting plate 23 is hinged to the first support 21, and the other end is detachably connected to the second support 22. The pressing block 24 is fixedly arranged at the bottom of the connecting plate 23 and is used to press and position the top surface of the pressure plate.

[0030] In this embodiment, the placement groove 11 is a cuboid through groove, the width of which is slightly larger than the width of the bottom plate of the positioning piece, and the positioning post 12 is cylindrical, the width of which is slightly smaller than the diameter of the positioning hole.

[0031] When fixing the positioning piece, first separate the end of the connecting plate 23 from the second support 22. Then, rotate the connecting plate 23 so that the top of the placement groove 11 is unobstructed. Next, align the positioning hole on the positioning piece with the positioning post 12 and put the positioning piece on the positioning post 12 so that the positioning piece is inserted into the placement groove 11. Then, rotate the connecting plate 23 again so that the pressing block 24 at the bottom of the connecting plate 23 presses on the top of the positioning piece to position and restrict the top of the positioning piece. At the same time, fix the end of the connecting rod 23 to the second support 22 to complete the positioning and fixing of the positioning piece.

[0032] This application can quickly position the pressure plate using the positioning post 12 to prevent the pressure plate from shifting to the left or right. The placement groove 11 can restrict the pressure plate to prevent it from rotating around the positioning post 12. The pressing block 24 can limit the top of the positioning plate to prevent it from shifting upwards, thus improving the positioning and fixing effect of the positioning plate.

[0033] In a preferred embodiment, such as Figure 3 As shown, the top surface of the second support 22 is provided with a receiving groove, and a groove 221 is recessed inward on the inner wall of the receiving groove. A fixing member 25 is provided in the groove 221, and the end of the connecting plate 23 away from the first support 21 is fixed in the receiving groove by the fixing member 25.

[0034] In this embodiment, when the end of the connecting plate 23 is rotated into the receiving groove, the connecting plate 23 is fixed by the fixing member 25, and the connecting plate 23 and the second support 22 are detachably connected by the fixing member 25.

[0035] In a preferred embodiment, such as Figure 3 As shown, the fixing member 25 includes a slide rod 251 arranged in the horizontal direction. The slide rod 251 is slidably connected to the second support 22. One end of the slide rod 251 is fixedly connected to a limiting plate. A spring 252 is sleeved on the outside of the slide rod 251. One end of the spring 252 is fixedly connected to the inner wall of the groove 221, and the other end is fixedly connected to the limiting plate. A fixing block 253 is fixedly provided at the end of the limiting plate away from the spring 252. A fixing hole 231 is opened at the end of the connecting plate 23 away from the first support 21. The fixing hole 231 matches the fixing block 253.

[0036] In this embodiment, after the connecting plate 23 rotates into the receiving groove, the slide rod 251 is pulled away from the receiving groove, so that the spring 252 is compressed and the fixing block 253 is stored in the groove. After the end of the connecting plate 23 is completely inserted into the receiving groove, the slide rod 251 is released, and the elastic force of the spring 252 drives the fixing block 253 to be inserted into the fixing hole 231 for fixation, thus completing the fixation of the connecting plate 23 and realizing the fixation of the positioning piece.

[0037] In a preferred embodiment, such as Figure 2 As shown, the bottom of the first support 21 and the second support 22 are both connected to a height adjustment component 3. The height adjustment component 3 is connected by a synchronization component 4 and is used to drive the first support 21 and the second support 22 to rise and fall synchronously in the vertical direction.

[0038] In this embodiment, by adjusting the height of the first support 21 and the second support 22, the pressing block 24 on its top can press the pressure sheet of different thicknesses, thus expanding its applicable range.

[0039] Preferred, such as Figure 2, Figure 4 , Figure 5 and Figure 6 As shown, at least two sets of first supports 21 and second supports 22 are provided, and the first supports 21 and second supports 22 correspond one-to-one. The first supports 21 are fixedly connected to each other by the first connecting rod 26, and the second supports 22 are fixedly connected to each other by the second connecting rod 27.

[0040] The height adjustment assembly 3 includes a rotating cylinder 31, a threaded rod 32, a worm gear 33, and a worm 34. The rotating cylinder 31 is vertically mounted on the placement platform 1 and is rotatably connected to the placement platform 1. The rotating cylinder 31 is hollow inside and its opening faces upward. The threaded rod 32 is threaded inside the rotating cylinder 31, and the top of the threaded rod 32 is fixedly connected to the first support 21 and / or the second support 22. The worm gear 34 is fixedly mounted on the outside of the rotating cylinder 31. A rotating rod is rotatably mounted on one side of the worm gear 34, and a worm 33 is coaxially mounted on the rotating rod. The worm 33 is meshed with the worm gear 34. The synchronization assembly 4 is connected to the two sets of rotating rods and is used to drive the two sets of rotating rods to rotate synchronously.

[0041] In this embodiment, two sets of first supports 21 and two sets of second supports 22 are provided. The two sets of first supports 21 are located at both ends of the placement platform 1. The second supports 22 correspond one-to-one with the first supports 21 and are also located at both ends of the placement platform 1. By providing two sets of first supports 21 and two sets of second supports 22, the pressing stability of the pressure plate can be improved.

[0042] Each set of rotating rods is coaxially equipped with two sets of worm gears, and the two sets of worm gears correspond one-to-one with two sets of worm wheels 33, which are used to synchronously drive the two sets of worm wheels 33 to rotate.

[0043] The synchronization assembly 4 includes a first synchronization pulley 41, a second synchronization pulley, a third synchronization pulley, a fourth synchronization pulley 42, and a drive motor 43. The drive motor 43 is fixedly connected to the end of one rotating rod, and the first synchronization pulley 41 is fixedly sleeved on the end of this rotating rod. The fourth synchronization pulley is fixedly sleeved on the outside of the other rotating rod. A rotating shaft is rotatably mounted on one side of the placement platform 1, and the second and third synchronization pulleys are fixedly sleeved on the rotating shaft. The first and second synchronization pulleys 41 and 42 are connected by a first synchronization belt 44, and the third and fourth synchronization pulleys 42 are connected by a second synchronization belt 45. The connection is achieved by driving two sets of rotating rods to rotate synchronously through the transmission of synchronous pulleys and synchronous belts, thereby driving four sets of rotating drums 31 to rotate synchronously. Since the first supports 21 are fixedly connected by the first connecting rod 26 and the second supports 22 are fixedly connected by the second connecting rod 27, under the constraint of the first connecting rod 26 and the second connecting rod 27, the four sets of threaded rods 32 rise and fall synchronously, thereby driving the first supports 21 and the second supports 22 to rise and fall synchronously, completing the height adjustment of the first supports 21 and the second supports 22, so that they can press and position pressure plates of different thicknesses, expanding their application range.

[0044] In a preferred embodiment, such as Figure 2 As shown, a rubber pad is fixedly installed at the bottom of the pressing block 24. Specifically, the rubber pad can prevent the pressing block 24 from directly contacting the pressure plate, protect the top surface of the pressure plate, and prevent scratches from being caused to the top surface of the pressure plate during the pressing process.
