Description

Technical Field

[0001] This utility model relates to the field of fixtures, specifically a fixture for machining sliders with adaptive positioning and clamping function. Background Technology

[0002] In the field of mechanical manufacturing, sliders, as a key mechanical component, are widely used in various transmission devices, guiding mechanisms, and automated equipment. Their machining accuracy and quality directly affect the performance and stability of the entire mechanical system. With the continuous development of industrial technology, increasingly higher requirements are being placed on the machining accuracy, production efficiency, and machining adaptability of sliders. Currently, in the slider machining process, fixtures play a crucial role as important tools for fixing and positioning sliders to ensure machining accuracy. A Chinese utility model patent (publication number: CN221911594U) discloses a fixture for slider machining. Through a relative movement component, two clamping blocks can be driven to move relative to each other, clamping the slider workpiece through two rotating blocks, thus facilitating the fixed machining of the slider workpiece. Through a rotation adjustment component, one of the rotating blocks can be driven to rotate, allowing the slider workpiece to rotate between the two clamping blocks through the two rotating blocks. This reduces the need to remove the slider workpiece, adjust the angle, and re-clamp it, thereby improving the efficiency of slider workpiece machining.

[0003] However, the above-mentioned device still has some shortcomings in use. Specifically, the device can only position one slider at a time, resulting in low slider positioning efficiency, which affects the processing and production of sliders. In addition, during the processing, the flying debris will directly collide with the screw, affecting its service life. Therefore, in order to address the above issues, a slider processing fixture with adaptive positioning and clamping function is proposed. Utility Model Content

[0004] To address the problem that existing technologies can only position one slider at a time, resulting in low slider positioning efficiency and affecting slider processing and production, this utility model proposes a slider processing fixture with adaptive positioning and clamping function.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a slider processing fixture with adaptive positioning and clamping function, including a fixed seat, an installation groove is opened through the top of the fixed seat, and protrusions are fixedly installed at equal intervals on the top of the fixed seat, and the four protrusions cooperate with the fixed seat to form three placement cavities.

[0006] A threaded rod is rotatably mounted on one side of the inner wall of the mounting slot. A drive shaft is fixed to one end of the threaded rod. A guide rod is detachably mounted on the mounting slot. The guide rod is located directly above the threaded rod. The diameter of the guide rod is larger than the diameter of the threaded rod. Three moving blocks are equidistantly threaded on the threaded rod. The moving blocks slide with the guide rod. After the top of each moving block protrudes from the mounting slot, a limit block is fixed. The limit block is located on the placement cavity.

[0007] Preferably, a through hole is provided on one side of the fixed base, the drive shaft is clearance-fitted with the through hole, and one end of the drive shaft that passes through the through hole is connected to an external drive source.

[0008] Preferably, threaded grooves are provided on both sides of the outer wall of the fixed base, and through holes that connect to the mounting groove are provided on the threaded grooves, with the through holes fitting with the guide rod with clearance.

[0009] Preferably, when the guide rod is assembled on the mounting groove, a limit cap is fitted into the threaded hole.

[0010] Preferably, one side of the limiting cover has a circular groove that abuts against the end of the guide rod.

[0011] Preferably, a cross block is fixed to the outer wall of the limiting cover.

[0012] Preferably, the outer wall of the movable block is provided with screw holes and round holes, the screw holes are threaded to the threaded rod, and the round holes are clearance-fitted to the guide rod.

[0013] Preferably, the sidewalls of both the protrusion and the limiting block are provided with rubber pads, and the rubber pads have anti-slip textures.

[0014] The advantages of this utility model are: 1. Through the structural design of the fixed seat, protrusion, placement cavity and limiting block, when processing sliders using this device, after placing multiple sliders on the placement cavity, the sliders can be clamped and positioned by the synchronous movement of multiple limiting blocks, thereby improving the working efficiency of slider processing and reducing the labor intensity of repetitive operations for workers. 2. In this utility model, the guide rod is positioned directly above the threaded rod, and the diameter of the guide rod is larger than that of the threaded rod. The guide rod can provide a certain degree of protection for the threaded rod, reducing the occurrence of debris directly impacting the threaded rod and affecting its service life. In addition, the guide rod is easy to disassemble and replace, facilitating subsequent maintenance. Attached Figure Description

[0018] 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 scope of protection of the present utility model.

[0019] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a fixture for machining sliders with adaptive positioning and clamping function. (Refer to...) Figures 1-5 A slider machining fixture with adaptive positioning and clamping function includes a fixed base 1. The top of the fixed base 1 has a through-hole mounting groove 10. The fixed base 1, as the basic load-bearing component of the entire fixture, is cast from high-strength alloy steel and has good rigidity and stability. It can withstand the cutting force and vibration generated during slider machining. The through-hole mounting groove 10 on its top is a rectangular structure. The depth of the mounting groove 10 is calculated to ensure that the moving block 6 will not interfere with the bottom of the fixed base 1 when it moves in the groove. The top of the fixed base 1 is fixedly mounted with protrusions 2 at equal intervals. The four protrusions 2 cooperate with the fixed base 1 to form three placement cavities 3.

[0020] A threaded rod 4 is rotatably mounted on one side of the inner wall of the mounting groove 10. A drive shaft 40 is fixed to one end of the threaded rod 4. A guide rod 5 is detachably mounted on the mounting groove 10. The guide rod 5 is located directly above the threaded rod 4. The diameter of the guide rod 5 is larger than the diameter of the threaded rod 4. Three moving blocks 6 are equidistantly threaded on the threaded rod 4. The moving blocks 6 slide with the guide rod 5. The top of each moving block 6 protrudes from the mounting groove 10 and is fixed with a limit block 7. The limit block 7 is located on the placement cavity 3.

[0021] Reference Figure 1 , Figure 2 and Figure 3 A through hole 11 is provided on one side of the fixed base 1. The drive shaft 40 is clearance-fitted with the through hole 11. One end of the drive shaft 40 that passes through the through hole 11 is connected to a drive source. The drive source can be a motor or a manual wheel.

[0022] Reference Figure 1 , Figure 2 and Figure 3 Both sides of the outer wall of the fixed base 1 are provided with threaded grooves 12, and through holes 13 that connect to the mounting groove 10 are provided on the threaded grooves 12. The through holes 13 are clearance fit with the guide rod 5.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 When the guide rod 5 is assembled on the mounting groove 10, the threaded part of the through hole 13 is fitted with the limit cover 8.

[0024] Reference Figure 1 and Figure 5 The limiting cover 8 has a circular groove 80 on one side, which abuts against the end of the guide rod 5. A cross block is fixed on the outer wall of the limiting cover 8. The diameter of the circular groove 80 matches the diameter of the end of the guide rod 5, so that it can abut against the end of the guide rod 5 tightly. The cross block fixed on the outer wall of the limiting cover 8 makes it convenient for operators to tighten and disassemble, improving the maintenance and adjustment efficiency of the fixture.

[0025] Reference Figure 4 The outer wall of the movable block 6 is provided with screw holes and round holes respectively. The screw holes are threaded to the threaded rod 4, and the round holes are clearance-fitted to the guide rod 5.

[0026] Reference Figure 1 , Figure 2 and Figure 4 Both the protrusion 2 and the limiting block 7 have rubber pads on their sidewalls. The rubber pads have anti-slip textures to increase the friction with the slider surface and prevent the slider from shifting during processing.

[0027] Working principle: When using this fixture to process a slider, first place the slider to be processed in the placement cavity 3. Then, start the external drive source, which drives the drive shaft 40 to rotate. Since the drive shaft 40 is fixedly connected to the threaded rod 4, the threaded rod 4 rotates accordingly. During the rotation of the threaded rod 4, the three moving blocks 6 that are threadedly engaged with it will move along the axial direction of the threaded rod 4. At the same time, under the guidance of the guide rod 5, the moving blocks 6 can only move in a straight line and will not rotate. As the moving blocks 6 move, the limiting block 7 fixed on its top will also move accordingly. When the limiting block 7 contacts the slider in the placement cavity 3, continue to drive the threaded rod 4 to rotate. The limiting block 7 will apply pressure to the slider. Through the friction between the rubber pad and the slider surface, the slider is firmly clamped in the placement cavity 3. The three moving blocks 6 can adaptively adjust their positions on the threaded rod 4 according to the actual size and placement position of the slider to meet diverse processing needs. After the slider is processed, reverse the drive of the threaded rod 4 to separate the limiting block 7 from the slider, and the processed slider can be taken out.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
