Description

Technical Field

[0001] This application relates to the field of tooling technology, and in particular to a grooved elastic pad close-fitting support tooling. Background Technology

[0002] The "limiting groove" on the ballastless track base plate is a key structure for placing the track slab, requiring extremely high positional accuracy. Traditional methods of fixing it are not secure, and displacement or deformation easily occurs during concrete pouring. The groove elastic padding close-fitting support fixture is an integrated support tool adapted to the groove structure. Its core utilizes elastic materials and a fitted design to achieve a tight fit and stable support for the elastic padding. It employs a structural design that precisely matches the groove contour, and the elastic components can adapt to padding tolerances and installation gaps, ensuring a gapless close fit between the padding and the inner wall of the groove, while preventing padding displacement and deformation through uniform support force, and also offering convenient installation. In existing technology, when the device is in use, it lacks a synchronously adjustable structure, making it inconvenient to limit the tight fit of the elastic padding in different grooves. Therefore, improvements to the existing technology are needed. Utility Model Content

[0003] The purpose of this invention is to provide a grooved elastic pad close-fitting support fixture, which solves the problem that when the device is in use, the lack of a synchronous linkage adjustment structure makes it inconvenient to limit the close-fitting of different grooved elastic pads.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a grooved elastic pad close-fitting support fixture, including a first limiting member and a second limiting member. A connecting block is fixedly connected to the outer side of both the first and second limiting members. A spring is provided on the connecting block, and a fixing block is provided on the spring. A connecting shell is fixedly connected to the fixing block. A fixing post is fixedly connected to the outer side of the second limiting member, and a fixing rod is fixedly connected to the fixing post. A sliding sleeve is slidably connected to the outer side of the fixing rod. The sliding sleeve is fixedly connected to the first limiting member, and a lubrication mechanism is provided inside the sliding sleeve. By compressing the first and second limiting members to a designated position, the entire moving device is moved to a designated position on the grooved elastic pad close-fitting surface. Then, the first and second limiting members are released, causing them to contact the grooved elastic pad close-fitting surface, thereby limiting the grooved elastic pad close-fitting surface. This allows the device to limit grooved elastic pad close-fitting surfaces of different sizes.

[0005] Preferably, a handle is fixedly connected to the outer side of the connecting shell. The handle is made of iron. By designing the handle to be made of iron, the core advantage is that iron has high strength, high wear resistance, and strong resistance to deformation. Compared with materials such as plastic and wood, iron handles can withstand frequent gripping, pushing and pulling operations during the use of tooling, as well as possible external force collisions, and are not prone to problems such as breakage, deformation, and wear.

[0006] Preferably, the lubrication mechanism includes a groove, the fixed rod has a groove inside, the sliding sleeve has a threaded groove inside, a threaded block is threadedly connected inside the threaded groove, an annular sleeve contacts the outer side of the sliding sleeve, a threaded block is threadedly connected inside the annular sleeve, the annular sleeve is slidably connected to the outer side of the fixed rod, and a sealing sleeve is fixedly connected inside the annular sleeve. Lubricating oil is poured into the sliding sleeve, allowing the lubricating oil and ball bearings to lubricate the connection between the fixed rod and the sliding sleeve, making the device easy to use.

[0007] Preferably, the groove is provided with a ball bearing that contacts the sliding sleeve. By designing the ball bearing, the contact area of ​​rolling friction is smaller and the frictional resistance is significantly reduced, which effectively reduces the wear between the fixed rod and the sliding sleeve, avoids jamming and stuck phenomena, and ensures smoother relative sliding between the two.

[0008] Preferably, the sliding sleeve has an oil inlet inside, and a cover is threadedly connected to the inside of the oil inlet. By designing the oil inlet, when it is necessary to add lubricating oil, simply unscrew the cover to directly inject lubricating oil into the sliding sleeve without disassembling the core components of the tooling. The operation is simple and efficient, providing convenience for subsequent lubrication and maintenance.

[0009] Preferably, the inside of the sliding sleeve is in contact with a sealing sleeve, which is slidably connected to the fixed rod. By designing the sealing sleeve, the inside of the sliding sleeve can be sealed.

[0010] Preferably, a rotating block is fixedly connected to the threaded block, and the rotating block contacts the annular sleeve. By designing the rotating block, the threaded block can be driven to rotate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model incorporates components such as grooves, balls, oil inlets, covers, sealing sleeves, and annular sleeves. Through the threaded connection between the cover and the sliding sleeve, rotating the cover allows the oil inlet to open and close, facilitating the injection of lubricating oil into the sliding sleeve. The lubricating oil can directly reach the connection between the fixed rod and the sliding sleeve through the oil inlet, forming efficient lubrication with the balls, reducing frictional loss between components, and making the device easy to use.

[0013] 2. This utility model designs components such as connecting blocks, springs, fixing blocks, connecting shells, handles, and fixing columns. With the help of the linkage structure of springs, connecting blocks, and limiting components, the spring can be compressed by moving the first and second limiting components, the position of the limiting components can be adjusted, and after being released, the spring force is used to achieve limiting and fixing, so that the device can closely fit and limit the elastic pads of different sizes of grooves.

[0019] 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.

[0020] Please see Figures 1-4The grooved elastic pad tightly supports the tooling, including a first limiting member 1 and a second limiting member 2. Connecting blocks 3 are fixedly connected to the outer sides of both the first limiting member 1 and the second limiting member 2. A spring 4 is installed on the connecting block 3, and a fixing block 5 is installed on the spring 4. A connecting shell 6 is fixedly connected to the fixing block 5, and a handle 7 is fixedly connected to the outer side of the connecting shell 6. The handle 7 is made of iron. The core advantage of using iron as the material is its high strength, high wear resistance, and strong resistance to deformation. Compared to materials such as plastic and wood, the iron handle 7 can withstand frequent gripping and pushing / pulling operations during tooling use, as well as possible external impacts, and is less prone to breakage, deformation, and wear. To address issues such as the second limiting member 2 having a fixed post 8 fixedly connected to its outer side, a fixed rod 9 fixedly connected to the fixed post 8, and a sliding sleeve 10 slidably connected to the outer side of the fixed rod 9, the sliding sleeve 10 being fixedly connected to the first limiting member 1, and a lubrication mechanism 11 being provided inside the sliding sleeve 10, the device is moved to a designated position on the grooved elastic pad by compressing the first limiting member 1 and the second limiting member 2 to a designated position, and then the first limiting member 1 and the second limiting member 2 are released, thereby allowing the first limiting member 1 and the second limiting member 2 to contact the grooved elastic pad, thereby limiting the grooved elastic pad, so that the device can limit grooved elastic pads of different sizes.

[0021] Please see Figure 3 , Figure 4 The lubrication mechanism 11 includes a groove 111. The groove 111 is provided inside the fixed rod 9, and a ball bearing 112 is provided inside the groove 111. The ball bearing 112 contacts the sliding sleeve 10. By designing the ball bearing 112, the contact area of ​​rolling friction is smaller and the frictional resistance is significantly reduced, which effectively reduces the wear between the fixed rod 9 and the sliding sleeve 10, avoids jamming and jamming, and ensures smoother relative sliding between the two. The sliding sleeve 10 has an oil inlet 113 inside, and a cover 114 is threaded to the inside of the oil inlet 113. By designing the oil inlet 113, when it is necessary to add lubricating oil, simply unscrew the cover 114 to directly inject lubricating oil into the sliding sleeve 10 without disassembling the core components of the tooling. The operation is simple and efficient, providing convenience for subsequent lubrication and maintenance.

[0022] Please see Figure 4The sliding sleeve 10 has a sealing sleeve 115 inside, which is slidably connected to the fixed rod 9. By designing the sealing sleeve 115, the inside of the sliding sleeve 10 can be sealed. The sliding sleeve 10 has a threaded groove 117 inside, and a threaded block 118 is threadedly connected inside the threaded groove 117. The outer side of the sliding sleeve 10 has an annular sleeve 116 inside, and a threaded block 118 is threadedly connected inside the annular sleeve 116. A rotating block 119 is fixedly connected to the threaded block 118, and the rotating block 119 is in contact with the annular sleeve 116. By designing the rotating block 119, the threaded block 118 can be rotated. The outer side of the fixed rod 9 is slidably connected to the annular sleeve 116, and the sealing sleeve 115 is fixedly connected inside the annular sleeve 116. By pouring lubricating oil into the sliding sleeve 10, the lubricating oil and the ball bearing 112 can lubricate the connection between the fixed rod 9 and the sliding sleeve 10, making the device easy to use.

[0023] The specific implementation process of this utility model is as follows: Before the device is used, rotate the cover 114. The cover 114 rotates and the sliding sleeve 10 undergoes threaded movement, which causes the cover 114 to generate relative displacement. The cover 114 rotates out of the sliding sleeve 10. Then, lubricating oil is poured into the sliding sleeve 10 from the oil inlet 113, so that the lubricating oil and the ball bearings 112 can lubricate the connection between the fixed rod 9 and the sliding sleeve 10, making the device easy to use.

[0024] When the device is in use, the first limiting member 1 and the second limiting member 2 move inward. The first limiting member 1 and the second limiting member 2 drive the connecting block 3 to move. The movement of the connecting block 3 compresses the spring 4. At the same time, the movement of the first limiting member 1 drives the sliding sleeve 10 and other components to move. The movement of the second limiting member 2 drives the fixed column 8 to move. The movement of the fixed column 8 drives the fixed rod 9 to move. The movement of the fixed rod 9 drives the groove 111 to move. The movement of the groove 111 drives the ball 112 to move. After the first limiting member 1 and the second limiting member 2 and other components move to the designated position, the first limiting member 1 and the second limiting member 2 are moved to the designated position on the groove elastic pad. Then the first limiting member 1 and the second limiting member 2 are released. The elastic force of the spring 4 pushes the first limiting member 1 and the second limiting member 2 and other components to move, so that the first limiting member 1 and the second limiting member 2 contact the groove elastic pad, thereby limiting the groove elastic pad. This allows the device to limit the groove elastic pad of different sizes.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
