Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lathe tool arbors, and more specifically, to an assembled lathe tool arbor. Background Art
[0002] The main function of the turning tool bar is to fix the turning tool and ensure that the turning tool works stably on the lathe, thereby improving the accuracy and quality of the turned workpiece. During the turning process, the turning tool bar can also prevent vibration caused by factors such as cutting force and cutting heat, ensuring the stability of the cutting process. In addition, the turning tool bar can also improve production efficiency, by more firmly fixing the turning tool and simplifying the operation process, reducing tool change time, making lathe operation more convenient and quick.
[0003] Traditional turning tool shanks are usually fastened with screws to fix the blade. However, during continuous use, due to frequent vibrations, the screws are prone to loosening, causing the blade to shake unsteadily during cutting. This not only affects the cutting accuracy and effect, but is also likely to cause damage to the blade. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides an assembled turning tool arbor. The technical problem to be solved by the present invention is that the blade installed on the traditional turning tool arbor is not stable enough and the fixing screws are easy to loosen.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled turning tool arbor, comprising a arbor body, a mounting groove is provided inside the arbor body, a gasket is placed inside the mounting groove, a blade is fixedly connected to the top of the gasket, a first threaded hole is provided inside the mounting groove, a first fixing screw is threadedly sleeved inside the first threaded hole, and the gasket and the blade are movably sleeved on the first fixing screw, a placement groove is provided on the top of the arbor body, a clamping block is placed inside the placement groove, a second threaded hole is provided at the bottom of the placement groove, and the clamping block is rotatably sleeved on the outside of the second fixing screw, and a fixing component is provided on the top of the clamping block;
[0006] The fixing assembly includes a slide plate, the interior of the slide plate is fixedly connected to an intermediate plate, the interior of the slide plate is slidably connected to two latches, springs are fixedly connected between the two latches and the intermediate plate, the exteriors of the first fixing screw and the second fixing screw are fixedly connected to ratchet rings, and the latches are movably inserted into the tooth gaps of the ratchet rings.
[0007] like Figure 1-4As shown, the specific implementation method is: the blade can be initially fixed by setting a first fixing screw, and then the clamping block can be pressed against the blade by rotating the second fixing screw, so that the blade can be further fixed, and then the corresponding pins are pushed by two springs, so that the two pins are inserted into the tooth gaps of the corresponding ratchet rings, which can limit the first fixing screw and the second fixing screw, thereby preventing the first fixing screw and the second fixing screw from loosening, making the blade installation more stable, and preventing the blade from shaking and being damaged during the cutting process.
[0008] In a preferred embodiment, the tops of the two latches are fixedly connected with paddles.
[0009] The two paddles can facilitate pulling the latch when the blade needs to be removed, so that the latch is disengaged from the tooth gap of the ratchet ring, thereby releasing the fixation of the first fixing screw and the second fixing screw, making removal more convenient.
[0010] In a preferred embodiment, the first fixing screw and the second fixing screw are both hexagon socket screws.
[0011] The hexagon socket screws provided make disassembly more convenient.
[0012] In a preferred embodiment, the bottom surface of the placement groove is lower than the top surface of the blade.
[0013] The pressing block can press the blade by making the bottom surface of the placement groove lower than the top surface of the blade.
[0014] In a preferred embodiment, the bottom of the pressing block is provided with anti-slip grooves.
[0015] The anti-slip grooves can increase the friction between the contact surface of the pressing block and the blade, so that the pressing block can press the blade more stably.
[0016] Technical effects and advantages of the utility model:
[0017] 1. After passing through, screw the first fixing screw into the first threaded hole to preliminarily fix the blade, and screw the second fixing screw into the second threaded hole to compress the blade and further fix the blade;
[0018] 2. By pushing the corresponding pins through two springs, the two pins are inserted into the tooth gaps of the corresponding ratchet rings, which can limit the first fixing screw and the second fixing screw, thereby preventing the first fixing screw and the second fixing screw from loosening, making the blade installation more stable and preventing the blade from shaking and being damaged during the cutting process.
