[0002] A rack is a bar-shaped gear that, when used in conjunction with a cylindrical gear, can convert rotational motion into linear motion, or vice versa. It is a commonly used part in mechanical transmissions, mainly used to transmit power and motion. It is usually used in conjunction with a cylindrical gear to achieve the conversion between linear motion and rotational motion. The rack head trimming operation can remove defective ends and improve the quality of the rack.
[0003] The rack head cutting machine in the prior art generally includes a support base and a cutting machine. The support base is provided with a bar-shaped rack positioning groove for positioning the rack so that its position in the width direction is limited to a certain extent. The support base is also provided with a pressure plate that can feed toward one side wall of the rack positioning groove. The pressure plate is pushed so that the rack is clamped. However, this clamping method makes it difficult to change the position of the rack after it is clamped. Defects that occur after head cutting make it difficult for the rack to continue to step forward. The clamping needs to be released and manually pushed to adjust the position of the rack, which is rather troublesome. Therefore, the technology in this field proposes a rack clamping, positioning and head cutting tool to solve the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Reference Figure 1-Figure 3 The utility model provides an embodiment: a rack clamping and positioning cutting head tooling, including a bottom plate 1, the bottom plate 1 is used to be placed at the bottom of the cutting machine for auxiliary use, an electric push rod 2 is installed at one end of the bottom plate 1, the output end of the electric push rod 2 is fixedly connected to a connecting frame 3, one end of the connecting frame 3 is fixedly connected to a mounting frame 4, a motor 5 is installed on the outside of the mounting frame 4, the output end of the motor 5 is fixedly connected to a bidirectional threaded rod 6, the other end of the bidirectional threaded rod 6 is rotatably connected to the inner wall of the mounting frame 4, the outer side of the bidirectional threaded rod 6 is fixedly connected to a threaded block 7, the inner wall of the mounting frame 4 limits the threaded block 7, and the threaded block 7 is fixedly connected to the inner wall of the mounting frame 4. A clamping plate 8 is fixedly connected to the bottom, two limit blocks 15 are fixedly connected to the outside of the installation frame 4, and two limit grooves 16 are provided on the top of the bottom plate 1. The outside of the limit block 15 is slidably connected to the inside of the limit groove 16. The limit block 15 cooperates with the limit groove 16 to make the movement of the installation frame 4 more stable. The rack to be processed is placed on the top of the bottom plate 1 and below the installation frame 4. Then the motor 5 is started to drive the bidirectional threaded rod 6 to rotate, so that the two threaded blocks 7 drive the clamping plate 8 to move towards each other and clamp the two sides of the rack. This clamping method can be used for clamping racks of different sizes. A positioning component is fixedly connected to the top of the bottom plate 1.
[0024] Reference Figure 1-Figure 3The positioning assembly includes a suspension frame 17, the bottom of which is fixedly connected to the top of the base plate 1, and an electric push rod 18 is installed at the bottom of the suspension frame 17. The output end of the electric push rod 18 is fixedly connected to a mounting frame 19, and a fixing rod 20 is fixedly connected to the inside of the mounting frame 19. The outer side of the fixing rod 20 is slidably connected to three sliders 21, and the outer sleeve of the fixing rod 20 is provided with four springs 22. The function of the springs 22 is to quickly reset the pressing block 23 after it contacts racks of different specifications when the pressing block 23 moves downward, and one end of the other two springs 22 is fixedly connected to the outer side of the slider 21, and the other end is fixedly connected to the inner wall of the mounting frame 19. The bottom of the slider 21 is fixedly connected with a pressing block 23. Starting the electric push rod 18 causes the mounting frame 19 to move downward, so that the three pressing blocks 23 will be stuck between the teeth of the rack, exerting a downward force on the top of the rack, so as to facilitate the subsequent cutting machine to cut the rack.
[0025] Reference Figure 2-Figure 4 The outer side of the clamping plate 8 is fixedly connected with a fixing column 9, and the outer side of the fixing column 9 is fixedly connected with a pull rope 10. The outer side of the mounting frame 4 is fixedly connected with two winding racks 11. Two columns are installed on the winding rack 11 to change the force of the pull rope 10, so that the pull rope 10 changes the direction of the force when it passes around the winding rack 11, and acts on the pressure plate 14, so that the pressure plate 14 moves downward. The outer side of the mounting frame 4 is fixedly connected with a fixing plate 12, and the bottom of the fixing plate 12 is fixedly connected with two tension spring telescopic rods 13, and the tension spring telescopic rod 13 is set by the outer sleeve of the telescopic rod. The pull rope 10 is composed of a tension spring, which can quickly reset the pressure plate 14, and the pull rope 10 is a stretchable rope with strong elastic force. The bottom of the two tension spring telescopic rods 13 is fixedly connected with the pressure plate 14, and the other end of the pull rope 10 is fixedly connected to the bottom of the pressure plate 14. When the two splints 8 move, the fixed column 9 will pull the pull rope 10, and the pull rope 10 will apply force to the pressure plate 14, so that the pressure plate 14 moves down and presses the top of the rack. Auxiliary elastic compression can be performed before the two splints 8 clamp the rack to prevent the splint 8 from hitting the improperly placed rack and causing it to deviate by too large an angle.
[0026] Working principle: First, the rack to be processed can be placed on the top of the bottom plate 1 and below the mounting frame 4, and then the motor 5 is started to drive the bidirectional threaded rod 6 to rotate, so that the two threaded blocks 7 drive the clamping plates 8 to move towards each other and clamp the two sides of the rack. This clamping method can be used to clamp racks of different sizes. When the two clamping plates 8 move, the fixed column 9 will pull the pull rope 10, and the pull rope 10 will apply force to the pressure plate 14, so that the pressure plate 14 moves down to press the top of the rack, which can be clamped between the two clamps. Before the plate 8 clamps the rack, auxiliary elastic compression is performed to prevent the clamping plate 8 from hitting the improperly placed rack and causing it to deviate too much. Then the electric push rod 2 can be started to make the connecting frame 3 push the installation frame 4 forward, and the clamped rack will move forward together. When it is necessary to perform head cutting, the pushing action is stopped, and the electric push rod 2 18 is started to make the installation frame 2 19 move down, so that the three pressure blocks 23 will be stuck between the teeth of the rack, exerting a downward force on the top of the rack, so as to facilitate the subsequent cutting machine to cut the rack.
[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
