Abstract
Description
Technical Field
[0001] This utility model relates to the field of floating pressure head technology, and more specifically, to a floating pressure head structure that can quickly reset. Background Technology
[0002] A "floating pressure head" is a common device or design in the fields of machinery, manufacturing, or testing. Its main feature is that it can adaptively adjust its position or pressure within a certain range to adapt to the shape, thickness, or surface unevenness of the workpiece, thereby ensuring uniform pressure or stable contact.
[0003] Traditional floating pressure head structures have the following shortcomings: In traditional floating pressure head structures, when a cylindrical block is inserted into the workpiece, an arc-shaped groove is set on the surface of the workpiece's circular groove. This groove utilizes the compression deformation of elastic elements such as springs and rubber pads to absorb external pressure or displacement changes. When the pressure head contacts the workpiece, the springs and rubber pads are compressed, and the pressure head automatically adjusts its position according to the shape or height deviation of the workpiece. However, in practice, multiple sets of springs and rubber pads are typically designed. Over long-term use, the springs and rubber pads on one side may age, leading to uneven force on the pressure head and off-center loading. This can cause misalignment problems during multi-position pressing processes. Therefore, improvements are needed. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, this utility model provides a floating pressure head structure that can quickly reset, which has the advantage of consistent production quality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a floating pressure head structure capable of rapid reset, comprising a mounting base, a circular groove inside the mounting base, a connecting groove penetrating the bottom of the mounting base below the circular groove, a sphere placed inside the circular groove, a connecting rod extending through the connecting groove to the bottom of the mounting base welded below the sphere, an elastic pad uniformly slidably mounted inside the circular groove, a circular ring plate welded to the outer side of the mounting base, long grooves uniformly formed on the four sides of the circular groove, short grooves formed on the inner side of the circular ring plate, the long grooves and short grooves matching each other, a circular rod extending into the short groove welded to the rear side of the elastic pad, the front end of the circular rod penetrating the circular ring plate and extending to the outer side of the circular ring plate, a fixing block fixedly mounted at the front end of the circular rod, and a telescopic spring elastically mounted between the rear side of the elastic pad and the inner side of the short groove, the telescopic spring being movably sleeved on the outer side of the circular rod.
[0006] As a preferred embodiment of this utility model, a platform is welded below the connecting rod, an extrusion block is welded below the platform, a cover is movably sleeved on the outer side of the platform, an installation groove is provided at the bottom of the cover, a return spring is elastically installed between the upper side of the cover and the lower side of the mounting seat, empty grooves are evenly provided on the four sides of the installation groove, a movable groove is provided on the inner side of the empty groove, a roller is rolled inside the movable groove, and an elastic plate is adhered to the inner side of the movable groove.
[0007] As a preferred embodiment of this utility model, the number of elastic pads is four, and each of the four elastic pads has an arc-shaped groove on its inner side, which fits into the sphere.
[0008] In a preferred embodiment of this invention, the radius of the mounting groove is equal to the radius of the extrusion block, and the inner diameter of the cover is equal to the radius of the platform.
[0009] In a preferred embodiment of this invention, the width of the slot is smaller than the diameter of the roller, and the inner side of the roller is in contact with the outer side of the elastic plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. This utility model utilizes the synchronous elastic deformation of elastic pads and telescopic springs to move a ball within a circular groove, aligning the mounting groove with the center of the workpiece, thereby inserting the cylindrical block into the workpiece. Compared to traditional floating pressure head structures, this fast-resetting floating pressure head structure, by setting four sets of elastic pads and telescopic springs, enables them to deform synchronously, assisting the ball in moving within the circular groove. This reduces the elastic potential energy of the elastic pads and telescopic springs, thus decomposing the squeezing force on the ball. Simultaneously, it can synchronously push the ball back to its original position, improving the lifespan of the elastic pads and telescopic springs, and also achieving rapid resetting.
[0012] 2. This utility model inserts a cylindrical block into the mounting groove, so that the cylindrical block first contacts the arc surface of the roller and squeezes the roller, causing the roller to retract into the movable groove and squeeze the elastic plate. The elastic plate then pushes the roller to move outward and clamp and fix the cylindrical block laterally. Compared with the traditional floating pressure head structure, this floating pressure head structure, which can quickly reset, positions the cylindrical block through the roller, and the rotation of the roller assists in the installation and release of the roller, making it convenient to use.

[0020] 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.
[0021] like Figures 1 to 6 As shown, this utility model provides a floating pressure head structure capable of rapid reset, including a mounting base 1. A circular groove 3 is formed inside the mounting base 1. A connecting groove 4 penetrating the bottom of the mounting base 1 is formed below the circular groove 3. A ball 5 is placed inside the circular groove 3. A connecting rod 6 extending through the connecting groove 4 to the bottom of the mounting base 1 is welded below the ball 5. An elastic pad 14 is slidably installed inside the circular groove 3. A circular ring plate 15 is welded to the outside of the mounting base 1. Long grooves 19 are formed evenly on the four sides of the circular groove 3. Short grooves 22 are formed on the inner side of the circular ring plate 15. The long grooves 19 and the short grooves 22 are matched. A circular rod 17 extending into the short groove 22 is welded to the rear side of the elastic pad 14. The front end of the circular rod 17 penetrates the circular ring plate 15 and extends to the outer side of the circular ring plate 15. A fixing block 18 is fixedly installed at the front end of the circular rod 17. A telescopic spring 20 is elastically installed between the rear side of the elastic pad 14 and the inner side of the short groove 22. The telescopic spring 20 is movably sleeved on the outer side of the circular rod 17.
[0022] The cylindrical block to be processed is inserted into the mounting groove 9, causing the cylindrical block to press against the roller 12. This causes the roller 12 to move inward and press against the elastic plate 13, causing the elastic plate 13 to deform. At this time, the roller 12 moves to the inside of the movable groove 11, and the cylindrical block continues to move upward, causing the roller 12 to roll. Thus, the four rollers 12 apply pressure to the cylindrical block to fix it. Then, the cylindrical block is inserted into the workpiece. The arc grooves around the workpiece push the cylindrical block to shift towards the center of the arc grooves, thereby causing the cover 2 to shift and the platform 7 to shift. The platform 7, through the connecting rod 6, causes the ball 5 to shift, thus causing the ball 5 to press against the elastic pad 14, causing the elastic pad 14 to deform under the pressure. At this time, the elastic pad 14 is inside the circular groove 3. The movement of the part pushes the round rod 17 outward, thereby causing the elastic pad 14 to compress the telescopic spring 20, causing the telescopic spring 20 to deform. This causes the cover 2 and the platform 7 to shift as a whole, moving the cylindrical block to the center position of the workpiece. At this time, the mounting base 1 continues to move downward, causing the cover 2 to stop moving due to the compressive force of the workpiece. The mounting base 1 then drives the platform 7 to continue moving downward, causing the mounting base 1 to compress the return spring 21, causing the return spring 21 to deform. At this time, the compression block 8 pushes the cylindrical block out of the mounting groove 9, thereby inserting the cylindrical block into the workpiece. This causes the mounting base 1 to move upward and return to its original position. At this time, the telescopic spring 20 and the elastic pad 14 release their elastic potential energy and quickly return to their original position, pushing the ball 5 to the center position of the circular groove 3, causing the ball 5 to drive the platform 7 back to its original position.
[0023] The elastic deformation of the elastic pads 14 and the telescopic springs 20 causes the ball 5 to move inside the circular groove 3, aligning the mounting groove 9 with the center of the workpiece, thereby inserting the cylindrical block into the workpiece. Compared with the traditional floating pressure head structure, this floating pressure head structure with rapid reset function uses four sets of elastic pads 14 and telescopic springs 20 to deform synchronously, assisting the ball 5 to move inside the circular groove 3. This reduces the elastic potential energy of the elastic pads 14 and telescopic springs 20, thus decomposing the squeezing force of the ball 5. At the same time, it can also synchronously push the ball 5 to reset, improving the life of the elastic pads 14 and telescopic springs 20, and also achieving rapid reset.
[0024] Among them, a platform 7 is welded below the connecting rod 6, an extrusion block 8 is welded below the platform 7, a cover 2 is movably sleeved on the outside of the platform 7, an installation groove 9 is opened at the bottom of the cover 2, a return spring 21 is elastically installed between the upper side of the cover 2 and the lower side of the mounting seat 1, empty grooves 10 are evenly opened on the four sides of the installation groove 9, an movable groove 11 is opened on the inner side of the empty groove 10, a roller 12 is rolled inside the movable groove 11, and an elastic plate 13 is adhered to the inner side of the movable groove 11.
[0025] By inserting the cylindrical block into the mounting groove 9, the cylindrical block first contacts the arc surface of the roller 12, squeezing the roller 12 and causing it to retract into the movable groove 11 to squeeze the elastic plate 13. The elastic plate 13 then pushes the roller 12 outward to clamp and fix the cylindrical block laterally. Compared with the traditional floating pressure head structure, this floating pressure head structure, which can quickly reset, positions the cylindrical block through the roller 12, and the rotation of the roller 12 assists in the installation and release of the roller 12, making it easy to use.
[0026] There are four elastic pads 14, and each of the four elastic pads 14 has an arc groove 16 on its inner side, which fits into the sphere 5.
[0027] By setting four elastic pads 14, the elastic pads 14 can adapt to the left, right and back and forth movement of the ball 5. At the same time, the adjacent two elastic pads 14 can adapt to the oblique movement of the ball 5, which makes it easier to push the ball 5 to perform the reset operation.
[0028] The radius of the mounting groove 9 is equal to the radius of the extrusion block 8, and the inner diameter of the cover 2 is equal to the radius of the platform 7.
[0029] The pressing block 8 moves downward and is inserted into the mounting groove 9, causing the pressing block 8 to push out the cylindrical block, thereby inserting the cylindrical block into the workpiece.
[0030] The width of the slot 10 is smaller than the diameter of the roller 12, and the inner side of the roller 12 is in contact with the outer side of the elastic plate 13.
[0031] The width of the slot 10 is smaller than the diameter of the roller 12, thereby preventing the roller 12 from dislodging from the interior of the movable slot 11. When the roller 12 is squeezed, it squeezes the elastic plate 13, thereby pushing the roller 12 to move outward for squeezing and positioning.
[0032] Working principle and usage process of this utility model:
[0033] The cylindrical block to be processed is inserted into the mounting groove 9, causing the cylindrical block to press against the roller 12. This causes the roller 12 to move inward and press against the elastic plate 13, causing the elastic plate 13 to deform. At this time, the roller 12 moves to the inside of the movable groove 11, and the cylindrical block continues to move upward, causing the roller 12 to roll. Thus, the four rollers 12 apply pressure to the cylindrical block to fix it. Then, the cylindrical block is inserted into the workpiece. The arc grooves around the workpiece push the cylindrical block to shift towards the center of the arc grooves, thereby causing the cover 2 to shift and the platform 7 to shift. The platform 7, through the connecting rod 6, causes the ball 5 to shift, thus causing the ball 5 to press against the elastic pad 14, causing the elastic pad 14 to deform under the pressure. At this time, the elastic pad 14 is inside the circular groove 3. The movement of the part pushes the round rod 17 outward, thereby causing the elastic pad 14 to compress the telescopic spring 20, causing the telescopic spring 20 to deform. This causes the cover 2 and the platform 7 to shift as a whole, moving the cylindrical block to the center position of the workpiece. At this time, the mounting base 1 continues to move downward, causing the cover 2 to stop moving due to the compressive force of the workpiece. The mounting base 1 then drives the platform 7 to continue moving downward, causing the mounting base 1 to compress the return spring 21, causing the return spring 21 to deform. At this time, the compression block 8 pushes the cylindrical block out of the mounting groove 9, thereby inserting the cylindrical block into the workpiece. This causes the mounting base 1 to move upward and return to its original position. At this time, the telescopic spring 20 and the elastic pad 14 release their elastic potential energy and quickly return to their original position, pushing the ball 5 to the center position of the circular groove 3, causing the ball 5 to drive the platform 7 back to its original position.
