Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal cutting machine technology, and in particular to a quick clamping mechanism for metal cutting machines. Background Technology
[0002] Metal cutting machines are a type of mechanical equipment widely used in industrial production and manufacturing. They are mainly used to cut various materials into the required size and shape. Their working principle is generally to fix the workpiece on the base through a clamping mechanism, drive the cutting tool, and then cut or separate the workpiece by pressing the cutting tool with external force.
[0003] However, existing technologies have some problems: the clamping mechanisms used in current metal cutting machines generally achieve clamping through threaded drives, which cannot achieve rapid clamping. During the cutting process, the metal material may wobble, causing deviations in cutting accuracy and potentially threatening the personal safety of workers, thus having certain limitations. Therefore, we propose a rapid clamping mechanism for metal cutting machines. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a quick clamping mechanism for metal cutting machines. By using a clamping handle, clamping rod, linkage plate, and return spring, it achieves a quick clamping effect. After cutting, the return spring enables automatic reset, facilitating the next clamping operation and improving ease of use.
[0005] The purpose of this utility model is achieved as follows: A quick clamping mechanism for a metal cutting machine, comprising:
[0006] A base, wherein a fixed clamping plate is provided in the middle of the upper surface of the base, a movable clamping plate is provided on one side of the fixed clamping plate, and a cutting mechanism is provided at one end of the upper surface of the base;
[0007] The mounting bracket and the drive mechanism are located at the other end of the upper surface of the base, and the drive mechanism is located inside the mounting bracket, with one end of the drive mechanism mounted on the movable clamp.
[0008] Optionally, the driving mechanism includes a clamping rod and a clamping handle. One end of the clamping handle is provided with an eccentric shaft, and one end of the outer surface of the clamping handle is provided with a linkage plate. The eccentric shaft is movably connected to the linkage plate.
[0009] Optionally, a return spring is provided on the outer surface of the clamping rod, with one end of the return spring located on one side of the linkage plate.
[0010] Optionally, one end of the clamping rod is provided with a connecting shaft, one end of the movable clamping plate is provided on the outer surface of the connecting shaft, the upper surface of the base is provided with a slot, the lower end of the connecting shaft is provided with a connecting slide plate, and the connecting slide plate is slidably installed inside the slot.
[0011] Optionally, a rotating shaft is provided at one end of one side of the fixed clamping plate, and one end of the rotating shaft is provided on the base. A guide rail is provided at the other end of one side of the fixed clamping plate, and a limiting handle is provided above the guide rail. The limiting handle is engaged with the base.
[0012] Optionally, an angle gauge is provided on one side of the fixed clamp, and an index groove is provided on the upper surface of the base, with the index groove corresponding to the angle gauge.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. The clamping handle, clamping rod, and linkage plate provided in this utility model allow for the following operation: When the clamping handle is rotated, the eccentric shaft pushes the linkage plate, causing it to tilt. After tilting, the linkage plate is clamped, and the clamping rod is moved forward. This causes the movable clamping plate to slide towards one end of the fixed clamping plate, thus fixing the workpiece to be cut. This achieves the function of quick clamping, improving work efficiency and ease of use.
[0015] 2. With the reset spring provided by this utility model, after the cutting is completed, the operator only needs to loosen the clamping handle. Due to the characteristics of the reset spring, the linkage plate will be reset, and the clamping rod will move back and forth on the mounting frame as quickly as before. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 3 As shown in the embodiment of this utility model, a quick clamping mechanism for a metal cutting machine includes: a base 1, a fixed clamping plate 7 disposed in the middle of the upper surface of the base 1, a movable clamping plate 6 disposed on one side of the fixed clamping plate 7, and a cutting mechanism 2 disposed at one end of the upper surface of the base 1; a mounting frame 4 and a driving mechanism 5, the mounting frame 4 being disposed at the other end of the upper surface of the base 1, the driving mechanism 5 being disposed inside the mounting frame 4, and one end of the driving mechanism 5 being disposed on the movable clamping plate 6;
[0023] Specifically, such as Figure 1 As shown, during use, the workpiece to be cut is placed on the base 1, with one side of the workpiece in contact with the fixed clamping plate 7. After contact, the drive mechanism 5 is rotated, which drives the movable clamping plate 6 to slide to one end on the upper surface of the base 1, thus cooperating with the fixed clamping plate 7 to clamp and fix the workpiece. Then, the cutting mechanism 2 cuts the workpiece. After cutting, the drive mechanism 5 is released, and the drive mechanism 5 will drive the movable clamping plate 6 to automatically reset. This not only improves the clamping speed but also allows for automatic reset, facilitating the next clamping operation and improving ease of use. It effectively solves the problem that the existing clamping mechanism has too slow a clamping speed, which may cause the metal material to shake during processing, resulting in a deviation in cutting accuracy.
[0024] Furthermore, the drive mechanism 5 includes a clamping rod 501 and a clamping handle 502. One end of the clamping handle 502 is provided with an eccentric shaft 507, and one end of the outer surface of the clamping handle 502 is provided with a linkage plate 503. The eccentric shaft 507 is movably connected to the linkage plate 503. A return spring 504 is provided on the outer surface of the clamping rod 501, and one end of the return spring 504 is provided on one side of the linkage plate 503.
[0025] Specifically, such as Figures 1 to 3As shown, rotating the clamping handle 502 causes the eccentric shaft 507 to push the linkage plate 503, causing the linkage plate 503 to tilt. After tilting, it clamps the clamping rod 501, moving the clamping rod 501 forward. This causes the movable clamping plate 6 to slide towards one end of the fixed clamping plate 7, thus fixing the workpiece to be cut. After cutting, the operator only needs to release the clamping handle 502. Through the characteristics of the return spring 504, the linkage plate 503 will be driven to return to its original position. Then the clamping rod 501 will move back and forth quickly on the mounting frame 4 as before, thus achieving the function of rapid clamping and improving work efficiency.
[0026] Furthermore, a connecting shaft 505 is provided at one end of the clamping rod 501, and a movable clamping plate 6 is provided at one end on the outer surface of the connecting shaft 505. A slot 3 is provided on the upper surface of the base 1, and a connecting slide plate 506 is provided at the lower end of the connecting shaft 505. The connecting slide plate 506 is slidably installed inside the slot 3.
[0027] Specifically, such as Figure 1 and Figure 3 As shown, by using bolts to fix the connecting slide plate 506 and the connecting shaft 505 together, the movable clamping plate 6 can slide on the upper surface of the base 1 through the connecting slide plate 506, thereby providing precise linear motion, which helps to achieve accurate position control and positioning, and can effectively avoid the occurrence of deviation. Furthermore, through the connecting shaft 505, the movable clamping plate 6 can be rotated at one end of the clamping rod 501 to adjust the clamping angle.
[0028] Furthermore, a rotating shaft 8 is provided at one end of one side of the fixed clamping plate 7, and one end of the rotating shaft 8 is provided on the base 1. A guide rail 9 is provided at the other end of one side of the fixed clamping plate 7, and a limit handle 10 is provided above the guide rail 9. The limit handle 10 is engaged with the base 1.
[0029] Specifically, such as Figure 2 As shown, when in use, the upper limit handle 10 is pulled up to release the fixation of the fixed clamping plate 7. Through the rotating shaft 8, the guide rail 9 on one side of the fixed clamping plate 7 rotates along the limit handle 10 to adjust the angle, thereby changing the cutting angle of the workpiece. This achieves the ability to adapt to different cutting needs, realize multi-angle cutting, improve processing accuracy and efficiency, and has a simple structure and convenient operation.
[0030] Furthermore, an angle gauge 11 is provided on one side of the fixed clamping plate 7, and an index groove 12 is provided on the upper surface of the base 1, with the index groove 12 corresponding to the angle gauge 11.
[0031] Specifically, such as Figure 2As shown, during the rotation of the fixed clamping plate 7, observe the numbers on the angle table 11 to see which set of numbers corresponds to the index groove 12. This allows you to clearly know the rotation angle of the fixed clamping plate 7, thereby providing precise positioning and ensuring the accuracy and quality of the cutting.
[0032] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
