Description

Technical Field

[0001] The utility model relates to a fixed tool for processing long strip parts, belonging to the field of long strip part processing. Background Art

[0002] In the processing of long parts, it is crucial to ensure the stable fixation of the parts, which directly affects the processing accuracy and the quality of the finished product.

[0003] However, positioning fixtures often have design limitations. When clamping and positioning parts, they can easily obstruct critical machining locations on the part's sidewalls. This not only increases machining difficulty but can also lead to errors and defective products. Specifically, positioning fixtures typically utilize rigid clamping mechanisms, such as fixed fixtures or bolt clamps. When clamping the part, these fixtures often occupy a portion of the part's sidewalls. This obstruction is particularly pronounced when machining long parts. Because certain areas on the part's sidewalls are key or critical areas for machining, if these areas are obscured by the fixture, the machining tool loses direct access to these locations, preventing precise machining. Furthermore, the clamping force and position adjustment capabilities of traditional positioning fixtures are often inflexible, making them difficult to adapt to the machining requirements of long parts of varying sizes and shapes. Overtightening can cause part deformation or surface damage, while loosening can compromise part stability during machining. Furthermore, due to the limitations of the fixture structure, operators struggle to quickly and accurately adjust the clamping position and force during machining, further increasing both machining difficulty and cost. Utility Model Content

[0004] To address the deficiencies of the prior art, the present invention provides a fixed tooling for processing long parts, which has the advantages of improving the flexibility of the tooling and avoiding obstruction of the operator from processing the side wall of the part.

[0005] In summary, the present invention provides the following technical solutions: a fixed tool for processing long parts, comprising a processing table, two mounting rods fixedly connected to the upper surface of the processing table, and a plurality of bases slidably connected to the outside of the mounting rods, the two mounting rods being respectively arranged on the left side and the right side of the upper surface of the processing table, and the opposite side walls of the left and right bases are each provided with a positioning structure for fixing the long parts;

[0006] The positioning structure includes a frame fixed to opposite side walls of the left and right bases, a screw rotatably connected to the bottom wall of the frame, a twist cap fixedly connected to the top of the screw, a screw block threadedly connected to the outside of the screw, an elastic telescopic rod fixed to opposite side walls of the left and right screw blocks, a clamping block fixedly connected to the other end of the elastic telescopic rod, and a rubber pad fixedly connected to the other side of the clamping block.

[0007] The opposite side walls of the left and right bases are both provided with locking components for improving positioning stability.

[0008] Furthermore, the locking assembly includes mounting plates fixed on opposite side walls of the left and right bases, a connecting rod slidably connected to the inner side of the mounting plate, a positioning iron block fixedly connected to the bottom end of the connecting rod, and a magnet block magnetically attracted to the bottom of the positioning iron block.

[0009] The beneficial effect of adopting the above further scheme is: the locking assembly realizes the stable positioning of the base during the processing process through the cooperation of the mounting plate, connecting rod, positioning iron block and magnet block, effectively preventing the base from sliding or offsetting due to processing vibration or external force, thereby improving the accuracy and stability of long parts processing.

[0010] Furthermore, a pull ring is fixedly connected to the top of the connecting rod, and mounting grooves are provided on the left side of the upper surface and the right side of the upper surface of the processing table, and the magnet block is fixedly connected to the inner bottom wall of the mounting groove on the same side.

[0011] The beneficial effect of adopting the above-mentioned further scheme is: the design of the pull ring makes it easy for the operator to quickly and conveniently adjust the height of the connecting rod, and then adjust the adsorption force between the positioning iron block and the magnet block, so as to achieve rapid locking and release of the base. At the same time, the magnet block is fixed in the mounting groove of the processing table, ensuring the stability and position accuracy of the magnet block, and further enhancing the locking effect.

[0012] Furthermore, both front and rear ends of the mounting rod are bent downward, and both the front and rear ends of the mounting rod that are bent downward are fixedly connected to the upper surface of the processing table.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that this design of the mounting rod increases the stability of its connection with the processing table, improves the load-bearing capacity and anti-deformation ability of the overall structure, and at the same time, the downward-bent mounting rod also provides a more stable support surface for the base, reduces the shaking of the base during the processing, and is conducive to improving the processing quality.

[0014] Furthermore, a groove is provided on the upper surface of the processing table, and a placement plate is slidably connected to the inner side of the groove. A plurality of chip removal openings are provided on the upper surface of the placement plate, and an anti-slip pattern is provided on the outer surface of the placement plate.

[0015] The beneficial effects of adopting the above-mentioned further scheme are: the placement plate design with grooves and sliding connections makes it easy to replace or clean the placement plate as needed, thereby improving the flexibility of use and convenience of maintenance of the tooling. The chip removal port on the placement plate helps to collect debris generated during processing and keep the working area tidy. The anti-slip pattern increases the friction on the surface of the placement plate to prevent long parts from sliding during processing.

[0016] Furthermore, the front and rear sides of the screw block are fixedly connected with guide blocks, and the front and rear side walls of the frame are provided with sliding openings adapted to the guide blocks.

[0017] The beneficial effect of adopting the above further solution is that the cooperation between the guide block and the frame slide ensures the linear motion of the screw block during the rotation of the screw, avoids the deviation or jamming of the screw block, and improves the reliability and durability of the positioning structure.

[0018] Furthermore, the top end of the screw rod movably passes through the inner top wall of the corresponding frame body and extends to the inner side of the mounting opening of the corresponding twist cap to be fixedly connected to the corresponding twist cap.

[0019] The beneficial effect of adopting the above further solution is that it enables the operator to more easily rotate the twist cap to adjust the height position of the clamping block, thereby achieving precise fixation of the long parts.

[0020] Furthermore, the clamping block is fixedly connected to the end of the piston rod of the corresponding elastic telescopic rod, and the height and width of the rubber pad are respectively equal to the height and width of the clamping block.

[0021] The beneficial effects of adopting the above-mentioned further scheme are: the clamping block is fixedly connected to the end of the piston rod of the elastic telescopic rod, ensuring the uniform transmission of the clamping force and avoiding the deformation of parts caused by uneven clamping. The introduction of the rubber pad increases the contact area between the clamping block and the part, reduces the contact stress, prevents the surface of the part from being scratched or crushed, and at the same time improves the stability and reliability of the clamping.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] Through the design of elastic telescopic rods and adjustable clamping blocks, this tooling can closely fit long parts of different sizes and shapes, avoiding part deformation or processing errors caused by rigid clamping. At the same time, the rubber pads on the clamping blocks further reduce contact stress, preventing the surface of the part from being scratched or crushed, thereby improving processing accuracy and the quality of the finished product. The sliding design of the base on the mounting rod allows the operator to quickly adjust the base position as needed to accommodate long parts of different lengths. In addition, the height of the clamping block can be easily adjusted by rotating the twist cap to avoid obstructing the side wall of the part to be processed. This flexible adjustment method greatly improves the flexibility and convenience of the processing process. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] See also Figures 1 to 3 A fixed tooling for processing long parts includes a processing table 1, two mounting rods 2 fixedly connected to the upper surface of the processing table 1, and a plurality of bases 3 slidably connected to the outside of the mounting rods 2. The two mounting rods 2 are respectively arranged on the left and right sides of the upper surface of the processing table 1. The opposite side walls of the left and right bases 3 are provided with positioning structures for fixing the long parts.

[0030] like Figure 1 As shown, the positioning structure includes a frame 4 fixed to the opposite side walls of the left and right bases 3, a screw 5 rotatably connected to the inner bottom wall of the frame 4, a twist cap 6 fixedly connected to the top of the screw 5, a screw block 7 threadedly connected to the outside of the screw 5, an elastic telescopic rod 8 fixed to the opposite side walls of the left and right screw blocks 7, a clamping block 9 fixedly connected to the other end of the elastic telescopic rod 8, and a rubber pad 10 fixedly connected to the other side of the clamping block 9.

[0031] The opposite side walls of the left and right bases 3 are both provided with locking components for improving positioning stability.

[0032] It should be noted that the locking assembly includes a mounting plate 11 fixed on the opposite side walls of the left and right bases 3, a connecting rod 12 slidably connected to the inner side of the mounting plate 11, a positioning iron block 13 fixedly connected to the bottom end of the connecting rod 12, and a magnet block 14 magnetically attracted to the bottom of the positioning iron block 13. The locking assembly achieves a stable positioning of the base 3 during the processing process through the cooperation of the mounting plate 11, the connecting rod 12, the positioning iron block 13 and the magnet block 14, effectively preventing the base 3 from sliding or offsetting due to processing vibration or external force, thereby improving the accuracy and stability of the processing of long parts.

[0033] The top of the connecting rod 12 is fixedly connected with a pull ring 1201, and mounting grooves are provided on the left and right sides of the upper surface of the processing table 1. The magnet block 14 is fixedly connected to the inner bottom wall of the mounting groove on the same side. The design of the pull ring 1201 facilitates the operator to quickly and conveniently adjust the height of the connecting rod 12, and then adjust the adsorption force between the positioning iron block 13 and the magnet block 14, so as to realize the rapid locking and release of the base 3. At the same time, the magnet block 14 is fixed in the mounting groove of the processing table 1, ensuring the stability and position accuracy of the magnet block 14, and further enhancing the locking effect.

[0034] The front and rear ends of the mounting rod 2 are both bent downward, and the front and rear ends of the downwardly bent mounting rod 2 are fixedly connected to the upper surface of the processing table 1. This design of the mounting rod 2 increases the stability of its connection with the processing table 1, and improves the load-bearing capacity and anti-deformation ability of the overall structure. At the same time, the downwardly bent mounting rod 2 also provides a more stable support surface for the base 3, reduces the shaking of the base 3 during the processing process, and is conducive to improving the processing quality.

[0035] A groove is provided on the upper surface of the processing table 1, and a placement plate 15 is slidably connected to the inner side of the groove. Several chip removal openings are provided on the upper surface of the placement plate 15, and an anti-slip pattern is provided on the outer surface of the placement plate 15. The design of the placement plate 15 connected with the groove and the sliding connection makes it easy to replace or clean the placement plate 15 as needed, thereby improving the flexibility of use and the convenience of maintenance of the tooling. The chip removal opening on the placement plate 15 helps to collect debris generated during the processing and keep the working area clean. The anti-slip pattern increases the friction on the surface of the placement plate 15 to prevent long parts from sliding during the processing.

[0036] The front and rear sides of the screw block 7 are fixedly connected with guide blocks 16, and the front and rear side walls of the frame 4 are provided with sliding openings that are compatible with the guide blocks 16. The cooperation between the guide blocks 16 and the sliding openings of the frame 4 ensures the linear movement of the screw block 7 during the rotation of the screw rod 5, avoids the deviation or jamming of the screw block 7, and improves the reliability and durability of the positioning structure.

[0037] The top end of the screw 5 movably passes through the inner top wall of the corresponding frame 4 and extends to the inner side of the mounting opening of the corresponding twist cap 6 and is fixedly connected to the corresponding twist cap 6, so that the operator can more easily rotate the twist cap 6 to adjust the height position of the clamping block 9 and achieve precise fixation of the long parts.

[0038] The clamping block 9 is fixedly connected to the end of the piston rod of the corresponding elastic telescopic rod 8. The height and width of the rubber pad 10 are equal to the height and width of the clamping block 9 respectively. The clamping block 9 is fixedly connected to the end of the piston rod of the elastic telescopic rod 8, ensuring the uniform transmission of the clamping force and avoiding the deformation of parts caused by uneven clamping. The introduction of the rubber pad 10 increases the contact area between the clamping block 9 and the part, reduces the contact stress, prevents the surface of the part from being scratched or crushed, and at the same time improves the stability and reliability of the clamping.

[0039] In addition, the processing table 1 is made of high-strength, wear-resistant materials, such as high-quality steel or aluminum alloy, to ensure that it maintains flatness and stability during long-term use.

[0040] The surface of the mounting rod 2 is specially treated, such as chrome plating or spraying anti-rust paint, to improve its corrosion resistance and aesthetics. The mounting rod 2 and the processing table 1 can be connected by high-strength bolts or welding to ensure a firm and reliable connection and prevent loosening or falling off during use.

[0041] The screw 5 is made of high-strength alloy steel and has good wear resistance and fatigue resistance, ensuring that it can remain stable under long-term use.

[0042] The rubber pad 10 can be made of materials with different hardness and thickness to adapt to long parts of different materials and shapes, thereby improving the stability and adaptability of the clamping.

[0043] The working principle of the above embodiment is:

[0044] The operator can push the base 3 to slide on the mounting rod 2 as needed. During the sliding process, the base 3 remains connected to the mounting rod 2 while adjusting its position on the processing table 1. When the base 3 moves to the specified position, the connecting rod 12 is pushed downward. The connecting rod 12 then drives the positioning iron block 13 to insert into the mounting groove of the processing table 1, and the positioning iron block 13 is magnetically attracted to the magnet block 14, thereby locking the base 3 to prevent the base 3 from sliding during the processing process.

[0045] The operator drives the screw 5 to rotate by rotating the twist cap 6, and the rotation of the screw 5 further drives the screw block 7 threadedly connected thereto to move along the axis of the screw 5. During this process, the sliding of the guide block 16 in the sliding mouth ensures the smooth and linear movement of the screw block 7, avoiding deviation or jamming. As the screw block 7 moves up and down, the elastic telescopic rod 8 fixed to the opposite side wall thereof also moves accordingly, and the clamping block 9 fixedly connected to the end of the piston rod of the elastic telescopic rod 8 moves synchronously with the elastic telescopic rod 8. When the clamping block 9 moves to the specified height position, it clamps the part. At the same time, the The rubber pad 10 installed on the clamping block 9 will contact the part. The softness and high friction coefficient of the rubber pad 10 not only increase the contact area and reduce the contact stress, but also effectively prevent the surface of the part from being scratched or crushed. In addition, since long parts of different sizes and shapes require different clamping forces and positions, the elastic properties of the elastic telescopic rod 8 enable it to adapt to such changes. When the clamping block 9 contacts the surface of the part through the rubber pad 10, the elastic telescopic rod 8 will automatically adjust its expansion and contraction amount according to the contour and size of the part to ensure that the clamping block 9 can fit closely to the surface of the part and achieve stable clamping.
