Description

A rack and pinion transmission mechanism for a cutting machine Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to a rack and pinion transmission mechanism for a cutting machine. Background Technology

[0002] A cutting machine is a common material cutting device that can quickly cut sheet materials into the required size.

[0003] In the present technology, cutting machines generally use motors to drive blades to cut materials. The motors are usually driven by belts. Belts are popular because they are easy to install and maintain and have low cost. However, belts themselves also bring problems such as high noise and short life. Especially when the transmission distance is large, the belt transmission structure needs to occupy a lot of space, which increases the space occupied by the cutting machine and is not conducive to workers' activities in the workshop.

[0004] Therefore, a new method is needed to solve the above problems. Summary of the Invention

[0005] In order to solve the above problems, this utility model provides a rack and pinion transmission mechanism for a cutting machine.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a rack and pinion transmission mechanism for a cutting machine, including a machine base, a movable frame and a cutting mechanism, wherein the movable frame slides on the machine base, the cutting mechanism slides on the movable frame, the cutting mechanism is provided with a laser component for cutting, the cutting mechanism includes a housing and a drive motor, a rack for meshing with the drive motor is fixed on the movable frame, and the drive motor is used to drive the cutting mechanism to move along the rack.

[0007] By changing the cutting mechanism from belt drive to rack and pinion drive, the high precision and long life of the rack and pinion mechanism are utilized to reduce noise generated during operation and reduce the number of maintenance and replacement cycles of the transmission structure, thereby reducing the maintenance cost of the cutting machine to a certain extent.

[0008] Furthermore, the movable frame includes a main body, a track, and a limiting strip. The rack is fixed between the track and the limiting strip. The housing is provided with a groove for cooperating with the track and a protrusion for the limiting strip.

[0009] Through the above settings, the track and limit bar can enhance the stability of the cutting mechanism during operation, prevent vibration and sway during the movement of the cutting mechanism, reduce errors in the processing process, and ensure the overall stability of the equipment.

[0010] Furthermore, the movable frame can be detachably connected to drive components on both sides, and the drive components are provided with sealing plates, the sealing plates having fixing grooves that match the cross-section of the movable frame.

[0011] By setting the cutting mechanism to the movable frame from the side first, and then installing the sealing plates on both sides, excessive movement of the cutting mechanism can be prevented, thereby limiting the maximum movement distance of the cutting mechanism. At the same time, this setting also allows for more structures to be set on the slide and the convex strip to increase stability.

[0012] Furthermore, a side plate is installed on the side of the machine base, and a stabilizing joint is formed between the side plate and the machine base, with the bottom of the sealing plate located within the stabilizing joint.

[0013] With the above settings, the movable frame achieves high stability during movement, which further reduces errors generated during operation. It also further reinforces the sealing plate, preventing it from falling off and ensuring the overall integrity of the equipment.

[0014] Furthermore, the movable frame is provided with a protrusion, the rack is located on the protrusion, and the protrusion is provided with a movable groove.

[0015] With the above configuration, the protrusion can provide a certain amount of space for the gear on the output end of the drive motor, making the gear rotate more smoothly as it rotates and moves with the cutting mechanism.

[0016] Furthermore, the movable frame is slidably connected with abutment blocks, which are disposed on both sides of the cutting mechanism and are used to abut against the cutting mechanism.

[0017] With the above settings, the abutment block will move together with the cutting mechanism, which further enhances the stability of the cutting mechanism. It can also move in advance to plan the movement path of the cutting mechanism in advance, thereby further reducing errors.

[0018] Furthermore, a motor is provided on the abutment block, the output end of the motor meshes with the rack, and the abutment block slides on the track.

[0019] With the above configuration, the abutment block connected to the track can save space and reduce volume, thus playing a certain role in energy saving. At the same time, the smaller volume can also achieve higher mobility, making the abutment block more flexible when moving.

[0020] Compared with the prior art, the advantages of this utility model are:

[0021] By using a rack and pinion drive and then utilizing the limiting strips of the track to improve the stability of the cutting mechanism during its movement, the cutting machine retains the high stability of belt drive while overcoming the disadvantage of belt damage. Furthermore, since all the motors used for driving can be hidden inside the structure, and most of the structure is located above the machine platform, the space occupied by the entire cutting machine can be made more compact, which is conducive to the rational layout of the workshop space and increases the workers' activity space.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] As shown in Figures 1 to 3, a rack and pinion transmission mechanism for a cutting machine includes a machine base 1, a movable frame 2, and a cutting mechanism 3. The movable frame 2 slides on the machine base 1, and the cutting mechanism 3 slides on the movable frame 2. A laser component 31 for cutting is mounted on the cutting mechanism 3. The laser is used to cut the material on the machine base 1. The movable frame 2 is used to adjust the movement trajectory of the laser component 31 on the X-axis, and the cutting mechanism 3 is used to adjust the movement trajectory of the laser component 31 on the Y-axis. The laser component 31 also has a certain lifting capacity to adjust its movement trajectory on the Z-axis, thereby achieving full-angle adjustment capability and obtaining a more flexible movement trajectory to meet more complex cutting requirements. The cutting mechanism 3 includes a housing 32 and a drive motor. The movable frame 2 is fixed... A rack 21 is provided for meshing with the drive motor. The drive motor drives the cutting mechanism 3 to move along the rack 21. Through the above configuration, the transmission method of the cutting mechanism 3 is changed from the traditional belt drive to the rack and pinion 21 drive. Since the rack and pinion 21 has higher precision, it will not generate much noise during operation. Moreover, due to the high degree of fit, the frequency of maintenance can be reduced to a certain extent. Furthermore, the high precision of the rack and pinion 21 itself can also bring high precision to the positioning and movement of the cutting mechanism 3, thereby reducing working errors and improving cutting quality. It is also more conducive to meeting higher requirements for cutting trajectories. In addition, with a servo motor as the drive motor, the cutting accuracy can be further improved.

[0029] As shown in Figure 3, the movable frame 2 includes a main body 22, a track 23, and a limiting strip 24. A rack 21 is fixed between the track 23 and the limiting strip 24. The housing 32 has a groove 33 for engaging with the track 23 and a protrusion 34 for fitting within the limiting strip 24. The engagement of the track 23 with the groove 33 and the engagement of the limiting strip 24 with the protrusion 34 further enhances the stability of the cutting mechanism 3 during operation. Furthermore, the placement of the rack 21 between the track 23 and the limiting strip 24 further limits the vibration and sway generated during the movement of the cutting mechanism 3. Drive components 25 can be detachably connected to both sides of the movable frame 2. The drive components 25 drive the movable frame 2 to move along the X-axis. A sealing plate 26 is provided on the drive component 25, and the sealing plate 26 has a fixing groove matching the cross-section of the movable frame 2. The sealing plate 26 can... The sides of the movable frame 2 are sealed. During installation, the cutting mechanism 3 is first installed in place along the slide groove 33 and the limiting strip 24, and then the sealing plate 26 is fixed on both sides. This can prevent the cutting mechanism 3 from moving excessively. The side of the machine base 1 is equipped with a side plate 11, which forms a stable joint with the machine base 1. The bottom of the sealing plate 26 is located in the stable joint. The stable joint can reduce the swing of the movable frame 2 during movement to a certain extent, thereby further improving the cutting accuracy. At the same time, it can also ensure the connection strength between the movable frame 2 and the machine base 1 and improve the overall integrity of the equipment. The movable frame 2 is provided with a protrusion 27, and the rack 21 is located on the protrusion 27. The protrusion 27 is provided with a movable groove 28. The upper part of the protrusion 27 provides a certain amount of space for the gear at the output end of the drive motor, ensuring that the cutting mechanism 3 will not be interfered with by the movable frame 2 during movement.

[0030] As shown in Figure 3, abutment blocks 29 are slidably connected to the movable frame 2. The abutment blocks 29 are located on both sides of the cutting mechanism 3 and are used to abut against the cutting mechanism 3. The abutment blocks 29 can further enhance the stability of the cutting mechanism 3 during its operation. They can also reach a certain position in advance according to the settings to limit the end point of the path of the cutting mechanism 3, thereby improving the processing accuracy of the cutting mechanism 3. A motor is installed on the abutment block 29. The output end of the motor meshes with the rack 21. The abutment block 29 slides on the track 23. The motor makes the abutment block 29 move on its own, so that the cutting mechanism 3 can achieve the effect of the abutment block 29 following the cutting mechanism 3 without additional work.
