Detailed Embodiments

[0016] The following further describes the detailed embodiments of the present utility model with reference to the drawings.

[0017] Such as Figures 1-3As shown in the figure, a tooth bar grooving device includes an installation frame 1. A fixed box 2 is arranged at the inner bottom of the installation frame 1. A first motor 3 is arranged inside the fixed box 2. The upper end of the fixed box 2 is open. The output end of the first motor 3 is provided with a turntable 4. The turntable 4 is located inside the upper opening of the fixed box 2. The upper surface of the turntable 4 is symmetrically provided with bases 5 for placing the tooth bar 20. A cylinder 6 is arranged at the inner top of the installation frame 1. The output end of the cylinder 6 is rotatably connected with a clamping seat 7. Thread grooves are formed on the lower surfaces of both ends of the clamping seat 7 and the upper surface of the base 5. Fixed blocks 8 are arranged on one side of the base 5 and the clamping seat 7. Through holes are formed in the fixed blocks 8. It further includes a guide rod 9 for connecting the fixed blocks 8 on the base 5 and the clamping seat 7. The guide rod 9 is slidably connected with the fixed block 8 through the through hole. Blocks 10 are arranged at both ends of the guide rod 9. A support frame 11 is arranged on one side of the fixed box 2. A compressible cushion block 12 is arranged on the support frame 11. A positioning plate 13 is arranged on one side of the cushion block 12. A cutting box 14 is arranged inside the installation frame 1 and on one side of the fixed box 2. A second motor 15 is arranged inside the cutting box 14. The output end of the second motor 15 is provided with a cutting blade 16.

[0018] Before grooving both ends of the tooth bar 20, it is necessary to first fix the tooth bar 20 to the turntable 4. Specifically, one end of the tooth bar 20 is abutted against the positioning plate 13, and the cushion block 12 is prevented from being compressed. Then the tooth bar 20 is moved downward along the positioning plate 13 so that the tooth bar 20 is placed on the two bases 5. The external thread of the tooth bar 20 fits with the thread groove on the base 5, thus facilitating the protection of the external thread of the tooth bar 20. When the tooth bar 20 is placed on the two bases 5, one end of the tooth bar 20 is still in contact with the positioning plate 13. At this time, the shortest distance from the rotation center of the turntable 4 to both ends of the tooth bar 20 is equal. After the placement of the tooth bar 20 is completed, the cylinder 6 is started. The output end of the cylinder 6 extends and presses the tooth bar 20 through the clamping seat 7. When the clamping seat 7 and the base 5 complete the fixation of the tooth bar 20, the thread groove on the clamping seat 7 fits with the external thread of the tooth bar 20, so as to facilitate the protection of the external thread of the tooth bar 20. At the same time, due to the limitation of the guide rod 9, the clamping seat 7 can rotate following the base 5, and the base 5 can rotate following the turntable 4, so that the turntable 4, the base 5 and the clamping seat 7 can rotate synchronously. After the placement and fixation of the tooth bar 20 are completed, when grooving the tooth bar 20, both the first motor 3 and the second motor 15 are started. The first motor 3 drives the turntable 4 to rotate and drives the tooth bar 20 on the turntable 4 to rotate. When the tooth bar 20 rotates, it will slightly squeeze the cushion block 12 through the positioning plate 13, thus preventing the positioning plate 13 from hindering the rotation of the tooth bar 20. When the tooth bar 20 rotates, the second motor 15 drives the cutting blade 16 to cut one end of the rotating tooth bar 20, thus realizing the grooving of one end of the tooth bar 20. When one end of the tooth bar 20 completely passes through the cutting blade 16, the turntable 4 continues to rotate, so that the other end of the tooth bar 20 can be grooved.

[0019] Since the rotation of the lead screw 20 is used to groove one end of the lead screw 20 through the cutting blade 16, and the bottom of the groove is a flat surface. If the cutting blade 16 moves linearly closer to and cuts the lead screw 20, the bottom of the cut groove is an arc surface, and the grooving depth is uneven. By rotating the lead screw 20, the grooving depth of the groove can be accurately controlled, improving the grooving quality.

[0020] Furthermore, a housing 17 for covering the cutting blade 16 is provided on the cutting box 14. One side of the housing 17 is open, and a part of the cutting blade 16 is located outside the housing 17 through the opening on one side of the housing 17. The housing 17 can improve the operation safety. At the same time, when placing the lead screw 20, the guide rod 9 is located between the cutting blade 16 and the base 5, restricting the placement path of the lead screw 20, thereby improving the placement safety of the lead screw 20. At the same time, it is not necessary to turn off the second motor 15 when placing the lead screw 20, avoiding frequent startup of the second motor 15 and reducing its service life.

[0021] Furthermore, an arch 18 is provided at the inner top of the mounting frame 1 to improve the stability of the mounting frame.

[0022] Furthermore, a base table 19 is provided inside the fixing box 2, and the first motor 3 is arranged on the base table 19. The base 5 is used to control the placement height of the first motor 3, so that the cutting blade 16 can cut and groove from the central position of the lead screw 20.

[0023] Furthermore, after the lead screw 20 is fixed, there is a gap between the clamping seat 7 and the base 5, avoiding the situation that the lead screw 20 is not effectively fixed after the clamping seat 7 and the base 5 are in contact.

[0024] When the device is in use, it can realize grooving at both ends of a single lead screw 20 by controlling the rotation of the turntable 4. During this process, it is not necessary to re-dismantle and then re-fix the lead screw 20, which can improve the grooving efficiency of the lead screw 20 and has a good use effect.
