Description

Technical Field

[0001] The utility model relates to the technical field of profile processing, in particular to a special profile processing fixture. Background Art

[0002] Profiles are objects with certain geometric shapes made of iron or steel and materials with certain strength and toughness (such as plastic, aluminum, fiberglass, etc.) through rolling, extrusion, casting and other processes. Profiles can be divided into I-beams, channel steels, angle steels, round steels, etc.

[0003] According to the "Universal clamp for profile processing (publication number: CN 207873712 U; application number: 201820216518.2)" published on the patent website, the above application optimizes the problem that "the traditional clamp structure is a fixed design, which can only perform a single type of profile processing and clamping work, has poor practicality and high manufacturing cost, and different sizes of products need to produce different clamps separately, which takes too long to manufacture and has low efficiency."

[0004] However, in the production process of profiles, the complexity of the appearance design will directly affect the production cost. Designers need to simplify the design as much as possible and reduce the production cost under the premise of meeting functionality and aesthetics. Reasonable appearance design can improve production efficiency. By optimizing the appearance structure of the profile, the waste generated during the processing can be reduced and the utilization rate of materials can be improved. Therefore, in order to meet the use requirements, the useless parts of the profile will be removed as much as possible, so that the appearance of the profile is almost in a special state. When the universal clamp is used to fix some profiles with special shapes, the left and right sides cannot effectively contact the profile plane, and cannot be stably clamped, which is not convenient for subsequent processing of special-shaped profiles.

[0043] Embodiment III

[0044] Refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 On the basis of Embodiment I and Embodiment II, it is further obtained that the limiting mechanism 3 includes a limiting component 31, a supporting component 32 and a positioning component 33. The limiting component 31 is arranged at the left and right sides of the top of the fitting base 41, the supporting component 32 is arranged outside the limiting component 31, and the positioning component 33 is arranged inside the supporting component 32.

[0045] The limiting component 31 includes a sliding frame 3101 which is slidably connected to the left and right sides of the top of the fitting base 41 where the special-shaped workpiece 5 is located. The front and rear sides inside the sliding frame 3101 are fixedly connected with sliding blocks 3102 which are slidably connected to the front and rear sides inside the fitting base 41. The supporting component 32 includes a rectangular cylinder 3201 which is fixedly connected to the outside of the sliding frame 3101. A frame plate 3202 is arranged outside the rectangular cylinder 3201. A second threaded cylinder 3203 is fixedly connected inside the frame plate 3202. The left and right sides of the frame plate 3202 are fixedly connected with a first fixing frame 3204 which is fixedly connected to the outside of the rectangular cylinder 3201. The upper and lower sides of the frame plate 3202 are fixedly connected with a second fixing frame 3205 which is fixedly connected to the outside of the rectangular cylinder 3201. The positioning component 33 includes a second threaded rod 3301 which is threadedly connected to the inner circle of the second threaded cylinder 3203. A torsion block 3302 is fixedly connected to the outside of the second threaded rod 3301. The inner side of the second threaded rod 3301 is rotatably connected with a pressing plate 3303 which is slidably connected inside the rectangular cylinder 3201. The inner side of the pressing plate 3303 is in contact with the outside of the fitting base 41. Slide rods 3304 are fixedly connected to the outside of the pressing plate 3303 on the left and right sides of the second threaded rod 3301. The slide rods 3304 are slidably connected inside the frame plate 3202. A limiting piece 3305 is fixedly connected to the outside of the slide rods 3304.

[0046] Furthermore, the staff can move the sliding frames 3101 on the left and right sides to complete the positioning process of the left and right sides of the special-shaped workpiece 5, so that the special-shaped workpiece 5 is located inside the top of the fitting base 41 and cannot move left and right, increasing the stability of the special-shaped workpiece 5 when it is located inside the top of the fitting base 41, improving the stability of the special-shaped workpiece 5 during subsequent processing, improving the subsequent processing accuracy, and the staff only needs to rotate the torsion block 3302 to control the pressing plate 3303 to move back and forth to control whether the position of the sliding frame 3101 is fixed, which is convenient for the staff to adjust and fix the position of the sliding frame 3101, and the operation is simple and convenient for the staff to use.

[0047] During the actual operation process, when this device is used and the special-shaped workpiece 5 needs to be fixed, the staff first places the special-shaped workpiece 5 inside the fitting base 41, then moves the special-shaped workpiece 5 to the position inside the fitting base 41, and then the staff moves the sliding frames 3101 on the left and right sides to clamp the special-shaped workpiece 5, so that the sliding frames 3101 on the left and right sides are respectively in contact with the left and right sides of the special-shaped workpiece 5. Then the staff rotates the torsion block 3302, and the rotation of the torsion block 3302 drives the second threaded rod 3301 to rotate. The second threaded rod 3301 rotates and moves inward in the inner circle of the second threaded cylinder 3203. The inward movement of the second threaded rod 3301 drives the pressing plate 3303 to move inward. The inward movement of the pressing plate 3303 is in contact with the outside of the limiting component 31. At this time, the pressing plate 3303 completes the fixation of the position of the limiting component 31 through the friction generated by contacting the fitting base 41. At this time, the clamping process of the special-shaped workpiece 5 located inside the top of the fitting base 41 is completed;

[0048] After that, the staff moves the cylinder 1101 to the left and right sides, so that the fixed rocker arm 2101 moves to the position where the top of the special-shaped workpiece 5 is not to be processed. Then, the cylinder 1101 is started. When the cylinder 1101 starts, the telescopic rod 1102 drives the convex plate 1103 to move upward. When the convex plate 1103 moves upward, the rotating frame 1202 is driven by the rotating shaft 1201 to flip with the second rotating rod 1304 as the axis. At this time, the outer end of the rotating frame 1202 flips downward, driving the fixed rocker arm 2101 to flip downward until the plurality of rubber pressing blocks 2203 below the fixed rocker arm 2101 all move above the special-shaped workpiece 5. Then the staff closes the cylinder 1101 and keeps the position of the fixed rocker arm 2101 unchanged. After that, the staff rotates two torsion disks 2202 independently. When the torsion disks 2202 rotate, the first threaded rod 2201 is driven to rotate. When the first threaded rod 2201 rotates, it moves downward within the inner ring of the first threaded cylinder 2102. When the first threaded rod 2201 moves downward, it drives the rubber pressing block 2203 to move downward. When the rubber pressing block 2203 moves downward and contacts the top of the special-shaped workpiece 5, the fixation of the special-shaped workpiece 5 is completed. At this time, the fitting base 41 supports the special-shaped workpiece 5, and the sliding frames 3101 on the left and right sides cooperate to complete the limiting clamping of the special-shaped workpiece 5. And the rubber pressing block 2203 applies a downward force to complete the positioning of the special-shaped workpiece 5. The cooperation of the three completes the fixation process of the special-shaped workpiece 5. After that, the staff can start the processing equipment to process the fixed special-shaped workpiece 5.
