[0002] Thread turning inserts are cutting tools used to process internal and external threads. The inserts have different edge angles and geometric shapes, suitable for processing threads of different specifications and types. During the processing of thread turning inserts, cutting speed, cutting depth and feed rate will affect the processing efficiency and quality, so it is very important to choose suitable thread turning inserts and adjust the processing parameters according to actual processing requirements.

[0003] In the process of grinding thread turning inserts, a fixture is usually required to fix the thread turning inserts. However, there are differences in the diameters of the circular holes on thread turning inserts of different sizes. The existing thread turning insert fixture can generally only fix thread turning inserts with a single circular hole diameter during use, and is not suitable for thread turning inserts with different circular hole diameters. Its scope of application is relatively small. Therefore, an automatic grinding fixture for thread turning inserts is proposed. Utility Model Content

[0022] like Figures 1 to 3As shown, an automatic grinding fixture for a threaded turning blade 2 includes a fixture body 1, a blade 2 is arranged on the top of the fixture body 1, a mounting hole 3 is opened on the top of the blade 2, six inner support rods 4 are evenly distributed around the central axis of the mounting hole 3, a rotating component 5 is arranged on the top of the fixture body 1 to drive the six inner support rods 4 to disperse or gather, and a fixing component 6 with a rotating function is arranged on the top of each inner support rod 4. It should be noted that when clamping the blade 2, the six inner support rods 4 are first gathered by controlling the rotating component 5, and then the six inner support rods 4 are placed in the mounting hole 3. Inside, the rotating component 5 is controlled to disperse the six internal support rods 4, so that the six internal support rods 4 are used to support the inside of the mounting hole 3, so as to achieve the effect of clamping the blade 2 on the top of the fixture body 1, and then the six groups of fixing components 6 are rotated to a horizontal state respectively, and the blade 2 is pressed down and fixed on the top of the fixture body 1 by adjusting the six groups of fixing components 6. When the blade 2 is fixed, the fixture body 1 is installed on the processing table for processing. Since the six internal support rods 4 can be dispersed according to different circular hole diameters, the effect of internal support for different circular hole diameters can be achieved, which is suitable for fixing thread turning blades with different circular hole diameters.

[0023] like Figure 1 , Figure 2 As shown, the rotating assembly 5 includes a servo motor 51, and the servo motor 51 is fixedly installed at the bottom of the clamp body 1. The output end of the servo motor 51 extends to the top of the clamp body 1 and is fixedly connected to a gear 1 52. The top of the clamp body 1 is provided with six strip grooves 53 that are evenly distributed around the central axis of the mounting hole 3 and are interconnected. A slider 54 is movably installed inside each strip groove 53. Six inner support rods 4 are respectively fixedly installed on the top of the six sliders 54. A gear 2 55 is provided on the top of the clamp body 1. The gear 2 55 is meshed with the gear 1 52. An arc hole 56 is provided at the top of the gear 2 55 corresponding to the position of each inner support rod 4. The six inner support rods 4 respectively pass through the inside of the six arc holes 56. It should be noted that when the servo motor 51 is started, it can drive the gear 1 52 to reciprocate at a preset angle and speed, thereby driving the gear 2 55 to reciprocate. The reciprocating rotation of the gear 2 55 can drive the six inner support rods 4 to disperse or gather, and each inner support rod 4 then drives the slider 54 connected to itself to slide inside the corresponding strip groove 53.

[0024] like Figures 1 to 3As shown, the fixing assembly 6 includes a block 61, the top of each inner support rod 4 is fixedly installed with a block 61, one side wall of each block 61 is fixedly installed with two side plates 62, a rotating shaft 63 is movably installed between each adjacent two side plates 62, a rotating rod 64 is fixedly installed on the side wall of each rotating shaft 63, a threaded hole 65 is opened on the side wall of each rotating rod 64, a bolt 66 is movably installed inside each threaded hole 65, and the side wall of each rotating shaft 63 is fixedly installed with a rotating rod 64. A limit rod 2 68 is fixedly installed, and a limit rod 1 67 is arranged above each limit rod 2 68. Each limit rod 1 67 is fixedly connected to the adjacent side plate 62. It should be noted that by rotating the rotating rod 64 to a horizontal state, the limit rod 2 68 and the limit rod 1 67 will be in a fitted state. The function of the limit rod 2 68 and the limit rod 1 67 is mainly to prevent the rotating rod 64 from rotating excessively. At this time, the bolt 66 is rotated to gradually move downward to press the blade 2 down on the top of the clamp body 1.

[0025] like Figures 1 to 3 As shown, the bottom end of each bolt 66 is threadedly connected with a threaded ring 69, and the bottom of each threaded ring 69 is fixedly installed with an anti-skid pad 610. It should be noted that in order to further enhance the downward pressing and fixing effect on the blade 2, the threaded ring 69 can be threadedly connected to the bottom end of the bolt 66. When the bottom end of the bolt 66 gradually moves downward, the anti-skid pad 610 can be driven to contact the blade 2, thereby increasing the friction force and ensuring the downward pressing and fixing effect on the blade 2. When not in use, the threaded ring 69 can be rotated and separated from the bolt 66.

[0026] like Figure 1 , Figure 2 As shown, a positioning plate 7 is provided on the top of the clamp body 1, and a transmission component 8 is provided on the top of the clamp body 1 for driving the positioning plate 7 to move linearly back and forth. It should be noted that if the blade 2 is a regular triangle structure, after the positioning plate 7 is driven by the transmission component 8 to move linearly back and forth to a suitable position, one side of the blade 2 is made to fit with the positioning plate 7, which can help the blade 2 to be positioned to prevent the blade 2 from having an angle error after clamping so as not to affect the processing.

[0027] like Figure 1 , Figure 2 As shown, the transmission assembly 8 includes a groove 81, a groove 81 is opened on the top of the clamp body 1, a rotatable screw rod 82 is movably installed inside the groove 81, a movable block 83 is threadedly connected to the screw rod 82, and a handwheel 84 that drives the screw rod 82 to rotate is movably installed on the side wall of the clamp body 1, and the positioning plate 7 is fixedly installed on the top of the movable block 83. It should be noted that the screw rod 82 can be driven to rotate by rotating the handwheel 84, and the reciprocating rotation of the screw rod 82 can drive the movable block 83 to reciprocate in a straight line, and the movement of the movable block 83 will synchronously drive the positioning plate 7 to move.

[0028] In summary:

[0029] When clamping the blade 2, firstly, the six inner support rods 4 are gathered by controlling the rotating component 5, and then the six inner support rods 4 are placed inside the mounting hole 3, and then the rotating component 5 is controlled to disperse the six inner support rods 4, so that the six inner support rods 4 are used to support the inside of the mounting hole 3, so as to achieve the effect of clamping the blade 2 on the top of the fixture body 1, and then the six groups of fixing components 6 are rotated to a horizontal state respectively, and the blade 2 is pressed down and fixed on the top of the fixture body 1 by adjusting the six groups of fixing components 6. When the blade 2 is fixed, the fixture body 1 is installed on the processing table for processing. Since the six inner support rods 4 can be dispersed according to different circular hole diameters, the effect of supporting different circular hole diameters can be achieved, which is suitable for fixing thread turning blades with different circular hole diameters.
