Description

Technical Field

[0001] This application relates to the field of limiting tooling technology, and in particular to a groove limiting bracket tooling. Background Technology

[0002] The "limiting groove" on the ballastless track base plate is a key structure for placing the track slab, and its positional accuracy requirements are extremely high. To ensure accurate positioning of the limiting groove template, a groove limiting frame fixture is needed to fix the groove and meet the template spacing requirements in the horizontal and vertical directions. Traditional fixtures are prone to displacement or deformation during concrete pouring, and the mainstream groove limiting frame fixtures currently on the market generally have a fixed structure and lack flexible adjustment, making it difficult to adapt to groove workpieces of different models and sizes. Utility Model Content

[0003] The purpose of this utility model is to provide a groove limiting bracket tooling, which solves the problem that traditional tooling is mostly an integrated structure designed for a single specification of groove workpiece. Its core parameters such as the groove limiting arm spacing and fixed position are all preset fixed values. When the production demand changes to different models of groove workpieces, the operator needs to replace it with a special tooling of the corresponding specification. This not only requires the storage of multiple sets of tooling of different models, increasing the equipment procurement cost and warehousing management pressure, but also requires a lot of time for tooling disassembly, installation and debugging, which seriously slows down the production rhythm and reduces production efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a groove limiting frame tooling, including a limiting installation and fixing frame, a limiting support main arm fixedly connected to the left side of the limiting installation and fixing frame, guide grooves being provided at the top and bottom of the limiting support main arm, movable sleeve plates being slidably connected to the front and rear sides of the surface of the limiting support main arm, sliders being fixedly connected to the top and bottom of the inner wall of the movable sleeve plates, the sliders being slidably connected to the inner wall of the guide grooves, a groove limiting arm fixedly connected to the left side of the movable sleeve plates, and an adjustment and fixing mechanism fixedly connected to the surface of the movable sleeve plates.

[0005] Preferably, the adjusting and fixing mechanism includes a mounting block, which is fixedly connected to the left side of the movable sleeve plate. A positioning groove is provided on the left side of the limiting support main arm. An adjusting and fixing pin is provided inside the mounting block. The right side of the adjusting and fixing pin extends into the positioning groove. A toothed plate is fixedly connected to the left side of the adjusting and fixing pin. A control central gear is meshed on the surface of the toothed plate. The control central gear is movably connected inside the mounting block. A worm gear is fixedly connected to the bottom of the control central gear. A worm is meshed on the surface of the worm gear. The left side of the worm extends into the left side of the mounting block. The mounting block moves synchronously with the movable sleeve plate. Rotating the worm can drive the worm gear and the control central gear to rotate. The meshing of the control central gear and the toothed plate drives the adjusting and fixing pin to move left and right, so that the adjusting and fixing pin is inserted into or disengaged from the positioning groove of the limiting support main arm, thereby fixing and loosening the movable sleeve plate. The transmission characteristics of the worm gear have both labor-saving and self-locking functions, ensuring that it is not easy to loosen after fixing, and the operation is convenient and the positioning is reliable.

[0006] Preferably, a positioning plate is fixedly connected to the surface of the worm gear, and the surface of the positioning plate contacts the inner wall of the mounting block to form an axial limit, preventing the worm gear from moving axially when rotating or under force, ensuring that the worm gear and the turbine gear always maintain a precise meshing state, avoiding transmission failure or decreased adjustment accuracy due to worm gear displacement, and ensuring the stable operation of the adjustment and fixing mechanism.

[0007] Preferably, a positioning sleeve is provided on the right side of the worm gear surface. The surface of the positioning sleeve is fixedly connected to the surface of the movable sleeve plate, providing stable support for the right end of the worm gear and balancing the cantilever force caused by the length of the worm gear. This reduces bending deformation or shaking of the worm gear during rotation, ensures uniform meshing clearance with the turbine, and guarantees smooth and jam-free transmission.

[0008] Preferably, the toothed plate is provided with a slide rod inside, and the surface of the slide rod is fixedly connected to the inner wall of the mounting block to provide a guide trajectory for the toothed plate to move up and down, preventing the toothed plate from shifting or tilting laterally under the drive of the control central gear, ensuring that the toothed plate and the control central gear always maintain full engagement, avoiding deviation of the movement trajectory of the adjusting fixing pin due to toothed plate misalignment, and ensuring that the adjusting fixing pin can be accurately inserted into the positioning slot group.

[0009] Preferably, a knob is fixedly connected to the left side of the worm gear surface. The knob is located on the left side of the mounting block. Without the need for tools such as wrenches, the worm gear can be driven to rotate by manually turning the knob, thereby controlling the extension and retraction of the adjusting fixing pin. This simplifies the operation process of adjusting the fixing mechanism, makes the fixing and loosening of the moving sleeve plate faster, and reduces the dependence on the operator's skills.

[0010] Preferably, the surface of the knob is provided with a friction groove, which is located on the left side of the mounting block. When the operator's hands are oily, sweaty, or in a humid environment, the friction groove can effectively prevent slippage, ensure stable force when turning the knob, avoid interruption of adjustment or uneven force due to slippage, and ensure the smoothness and accuracy of worm gear rotation.

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

[0012] 1. This utility model, by adding guide grooves and sliders to the limiting support main arm, allows the moving sleeve and groove limiting arm to flexibly adjust their positions according to the size of the grooved workpiece. This eliminates the need for dedicated tooling for workpieces of different specifications, significantly reducing equipment costs, minimizing tooling changeover time, improving processing efficiency, and enhancing the adaptability of tooling to diverse production needs.

[0013] 2. This utility model, by adding a fixing mechanism and other structures to the limiting support main arm, avoids the groove limiting arm from shifting due to vibration and other factors during processing, ensures the positioning accuracy of the workpiece, reduces product scrap or rework caused by inaccurate positioning, and improves the stability and consistency of processing quality.

[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 Figure 1-4 The groove limiting bracket tooling includes a limiting installation and fixing bracket 1. A limiting support main arm 2 is fixedly connected to the left side of the limiting installation and fixing bracket 1. Guide grooves 3 are provided at the top and bottom of the limiting support main arm 2. Movable sleeve plates 4 are slidably connected to the front and rear sides of the surface of the limiting support main arm 2. Slider 5 is fixedly connected to the top and bottom of the inner wall of the movable sleeve plate 4. The slider 5 is slidably connected to the inner wall of the guide groove 3. A groove limiting arm 6 is fixedly connected to the left side of the movable sleeve plate 4. An adjustment and fixing mechanism is fixedly connected to the surface of the movable sleeve plate 4.

[0021] Please see Figure 1-4 The adjusting and fixing mechanism includes a mounting block 71, which is fixedly connected to the left side of the movable sleeve plate 4. A positioning groove group 72 is provided on the left side of the limiting support main arm 2. An adjusting and fixing pin 73 is provided inside the mounting block 71. The right side of the adjusting and fixing pin 73 extends into the interior of the positioning groove group 72. A toothed plate 74 is fixedly connected to the left side of the adjusting and fixing pin 73. A control central gear 75 is meshed on the surface of the toothed plate 74. The control central gear 75 is movably connected inside the mounting block 71. A worm gear 76 is fixedly connected to the bottom of the control central gear 75. A worm 77 is meshed on the surface of the worm gear 76. The left side of the worm 77 extends into the left side of the mounting block 71.

[0022] Furthermore, by controlling the setting of the central gear 75 and the toothed plate 74, the worm gear 77 can be rotated to easily control the action of the adjusting fixing pin 73. The adjustment process is labor-saving and convenient, reducing the labor intensity of the operator. At the same time, the self-locking characteristic of the worm gear 77 enables the adjusting fixing pin 73 to maintain a stable position after being inserted into the positioning slot group 72, avoiding the loosening of the moving sleeve 4 due to external force during processing, thus improving the limit stability and operating efficiency.

[0023] Please see Figure 1-4 A positioning piece 8 is fixedly connected to the surface of the worm gear 77, and the surface of the positioning piece 8 is in contact with the inner wall of the mounting block 71.

[0024] Furthermore, by setting the positioning plate 8, it is prevented from deviating from the preset meshing position during long-term use or in a vibrating environment, ensuring the continuity and accuracy of the worm gear 77 transmission, avoiding jamming or failure of the adjustment and fixing mechanism, extending the service life of the tooling, and improving the reliability and stability of the overall structure.

[0025] Please see Figure 1-4 The right side of the worm gear 77 is fitted with a positioning sleeve 9, and the surface of the positioning sleeve 9 is fixedly connected to the surface of the movable sleeve plate 4.

[0026] Furthermore, by setting the positioning sleeve 9, the deflection caused by its own weight or rotational force is effectively reduced, avoiding eccentricity or excessive clearance when the worm gear 77 meshes with the turbine, ensuring smooth transmission, reducing component wear, and ensuring precise movement of the adjusting fixing pin 73 during adjustment, thereby improving the operation feel and reliability of the adjusting fixing mechanism.

[0027] Please see Figure 1-4 The toothed plate 74 is provided with a slide rod 10 inside, and the surface of the slide rod 10 is fixedly connected to the inner wall of the mounting block 71.

[0028] Furthermore, by setting the slide bar 10, the toothed plate 74 can only move smoothly along a straight line, ensuring that its meshing state with the control center gear 75 is stable, avoiding transmission jamming or inaccurate positioning of the adjusting fixing pin 73 caused by the misalignment of the toothed plate 74, ensuring that the adjusting fixing mechanism can still accurately control the movement of the adjusting fixing pin 73 during long-term use, and improving positioning accuracy and structural stability.

[0029] Please see Figure 1-4 A knob 11 is fixedly connected to the left side of the surface of the worm 77, and the knob 11 is located on the left side of the mounting block 71.

[0030] Furthermore, by setting the knob 11, operators can directly complete the operation manually, which greatly shortens the time for fixing and adjusting the moving sleeve 4 and improves the ease of operation of the tooling; at the same time, it reduces operational obstacles caused by tool compatibility issues, improves the consistency of tooling use by different operators, and enhances the smoothness of the production process.

[0031] Please see Figure 1-4 The surface of the knob 11 is provided with a friction groove 12, which is located on the left side of the mounting block 71.

[0032] Furthermore, the friction groove 12 prevents the hand from sliding relative to the knob 11 during operation, ensuring that the operator can accurately control the rotation angle of the knob 11 and thus precisely adjust the position of the adjusting fixing pin 73; at the same time, it reduces operational errors or hand fatigue caused by slippage, improves operational safety and adjustment efficiency, and ensures the reliable use of the tooling under complex working conditions.

[0033] The specific implementation process of this utility model is as follows: When in use, first fix the limiting installation fixing bracket 1 in the pre-installation position, and then adjust the spacing of the groove limiting arms 6 according to the size of the groove. When it is necessary to adjust the spacing of the groove limiting arms 6, rotate the worm 77. The worm 77 drives the worm wheel 76 to rotate, the worm wheel 76 drives the control central gear 75 to rotate, the control central gear 75 drives the tooth plate 74 to move, the tooth plate 74 drives the adjusting fixing pin 73 to move, the adjusting fixing pin 73 exits the interior of the positioning groove group 72, and the moving sleeve 4 and the limiting support main arm 2 lose the fixing effect.

[0034] The movable sleeve 4 is pushed to move, which in turn drives the groove limiting arm 6 to move. The groove limiting arm 6 and the movable sleeve 4 drive the slider 5 to slide inside the guide groove 3. When the spacing of the limiting support main arm 2 is adapted to the size of the groove, the worm gear 77 is rotated in the opposite direction, so that the adjusting fixing pin 73 and the positioning groove group 72 are re-engaged.

[0035] 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.
