Technical Field

[0001] This utility model relates to the field of sawing fixture technology, and in particular to a universal positioning device for a double-headed sawing fixture. Background Technology

[0002] Profiles refer to solid straight bars of metal that have been plastically shaped and have a specific cross-sectional shape and size. Profiles come in a wide variety of specifications and have a broad range of applications, playing a very important role in rolling production.

[0003] Currently, when processing fixed-length profiles with inclined angles at both ends, due to the length tolerance fluctuations in the profile, a single fixture for multi-hole profiles of the same specification is limited to positioning parts with only one hole position. Often, the same specification of profile needs to be processed into multiple parts, and it is necessary to change the fixture to switch parts with different hole positions in order to achieve processing.

[0032] To better understand the purpose, structure, and function of this utility model, the following detailed description of a universal positioning device for a double-headed sawing fixture, in conjunction with the accompanying drawings, is provided.

[0033] like Figures 1-7 As shown, this utility model embodiment provides a universal positioning device for a double-head sawing fixture, including a processing table 100 for being fixed on the table surface for movement and support, and a fixing part 200 disposed on the upper end of the processing table 100 for fixing a profile 500 installed on the upper end. The profile 500 is placed inside the fixing parts 200 at both ends for installation. Supporting platforms 300 are provided on both sides of the lower end of the profile 500 for supporting the upper end of the profile 500. A positioning unit 400 for auxiliary fixing of the profile 500 is also movably installed on the upper end of the processing table 100.

[0034] The positioning unit 400 includes a mounting component 410 for mounting and positioning, and a positioning pin 430 fixedly mounted on the upper end of the mounting component 410 for fixing the profile 500. The mounting component 410 is slidably mounted on the upper end of the movable slider 420 mounted at the lower end, and is locked by a locking part 440 provided on one side.

[0035] The fixing part 200 includes a pressure plate part 210 for fixing both ends of the profile 500. A cutting saw blade 230 for cutting the profile 500 is provided on one side of the pressure plate part 210. The cutting saw blade 230 is installed and driven by a fixing frame 220 provided on one side. Both the pressure plate part 210 and the fixing frame 220 are installed on the upper surface of the processing table 100.

[0036] When it is necessary to fix the profile 500, the profile 500 can be placed on the upper end of the processing table 100 and then fixed using the pressure plates 210 at both ends. Then, adjust the sliding block 420 to move the mounting part 410 set at the upper end. After moving to the target position, the positioning pin 430 is installed into the through hole at the upper end of the profile 500, thereby fixing the profile 500. Profile 500 parts of the same specification but different hole positions do not need to be switched with fixtures, improving switching efficiency. One set of fixtures can realize the ability to process multiple profile 500 parts of the same specification but different hole positions, greatly reducing the fixture development cost.

[0037] The upper end of the processing table 100 is provided with a guide rail 110 for supporting the positioning unit 400. The movable slider 420 is slidably mounted on the upper end of the guide rail 110 to limit the positioning unit 400, so that it slides on the upper end of the guide rail 110 and adjusts its position.

[0038] A scale portion 120 for marking and indicating the position of the positioning unit 400 is provided on one side of the guide rail 110. The two ends of the scale portion 120 are fixedly mounted on the upper end of the processing table 100 by bolts. A marking pin 450 for auxiliary indication is provided on one side of the mounting part 410. The marking pin 450 is located at the upper end of the scale portion 120. The marking pin 450 is mounted on the side of the mounting part 410. The scale portion 120 is fixedly mounted on one side of the guide rail 110 to mark the position after the adjustment of the parts to be switched.

[0039] The upper end of the processing table 100 is provided with a tabletop mounting pin 140 for fixing the processing table 100. The processing table 100 is fixed to the upper end of the operating table by the tabletop mounting pin 140, which facilitates the installation and fixing of the processing table 100 and makes it easy to adapt to the positioning worktable.

[0040] The upper four corners of the processing table 100 are equipped with lifting rings 130 for moving the processing table 100. The lifting rings 130 are all installed inside the processing table 100 by bolt threads and can be connected to the lifting device to facilitate the moving of the processing table 100.

[0041] The lower end of the movable slider 420 is provided with a lifting unit 460 for positioning the movable slider 420. The lower end of the lifting unit 460 matches the upper end of the guide rail 110. The lifting unit 460 includes a locking handle 461 for adjusting the lifting unit 460 and a first bevel gear 462 fixedly installed at one end of the locking handle 461 for transmission. A second bevel gear 463 for driving the first bevel gear 462 is meshed on one side of the first bevel gear 462. An adjusting screw 465 for transmission is fixedly installed on one side of the second bevel gear 463. The adjusting screw 465 is installed through the lifting foot 464 installed at the lower end. The lifting foot 464 is installed inside the movable slider 420.

[0042] After the movable slider 420 moves to the designated position, the externally mounted locking handle 461 can be rotated to drive the first bevel gear 462 mounted at one end to rotate, which in turn meshes with the second bevel gear 463 mounted on one side to rotate. The adjusting screw 465 fixedly mounted drives the upper threaded lifting foot 464 to descend, thereby fitting against the guide rail 110 mounted at the lower end, fixing and locking the movable slider 420. The operation is relatively convenient and makes it easy to fix the movable slider 420, preventing the profile 500 from slipping during processing.

[0043] The lifting foot 464 has a rectangular cross-section and matches the size of the slot at the lower end of the movable slider 420. It is used to limit and fix the lifting foot 464 to prevent the lifting foot 464 from rotating when the adjusting screw 465 rotates. Limiting the lifting foot 464 makes it easier to push it down.

[0044] The lower end of the lifting foot 464 is fitted with a protective sleeve 466 for anti-slip operation. The protective sleeve 466 is attached to the lower end of the lifting foot 464 and fitted into the lower end of the movable slider 420 to prevent the lifting foot 464 from sliding when it is installed against the guide rail 110, thus further preventing slippage.

[0045] The working principle of a universal positioning device for a double-head sawing fixture is as follows: When it is necessary to fix the profile 500, the profile 500 can be placed on the upper end of the processing table 100, and then fixed by the pressure plates 210 at both ends. Then, the sliding block 420 is adjusted to move the mounting part 410 set at the upper end. After moving to the target position, the positioning pin 430 is installed into the through hole at the upper end of the profile 500, thereby fixing the profile 500. Profile 500 parts of the same specification but different hole positions do not need to be switched by fixture, improving switching efficiency. One fixture can realize the ability to process multiple profile 500 parts of the same specification but different hole positions, which greatly reduces the fixture development cost.

[0046] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
