Description

Technical Field

[0001] This utility model relates to the field of CNC machining equipment technology, specifically an arc drawing machine with a trigger-type protection structure. Background Technology

[0002] During the use of the arc drawing machine, the operator needs to hold the workpiece and put it into the arc drawing machine. The arc drawing machine has some rotation and pressing movements during operation. However, most current arc drawing machines lack safety protection structures. During operation, the operator's body is easily too close to the moving parts of the arc drawing machine, which can cause collisions and injuries to the operator.

[0003] According to a public notice of a protective structure for an arc drawing machine (Announcement No.: CN216369919U), the above application includes a protective plate and an elastic component. The protective plate is installed in conjunction with the arc drawing machine frame through the elastic component. The arc drawing machine frame is also provided with a first proximity sensor corresponding to the protective plate.

[0004] However, in actual use, the working area of ​​the arc-drawing machine is still suddenly exposed to the environment. The arc-drawing machine generates high temperatures during operation, and exposure may cause operators or bystanders to accidentally come into contact with the working area, resulting in burns. At the same time, the flying high-temperature metal particles or sparks can easily ignite flammable materials that may be present in the surrounding area, causing a fire risk. In view of this, we propose an arc-drawing machine with a trigger-type protection structure. Utility Model Content

[0005] The purpose of this invention is to provide an arc-drawing machine with a trigger-type protective structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an arc-drawing machine with a trigger-type protective structure, comprising a machine body, a housing fixedly connected to the side wall of the machine body, a placement seat fixedly connected to the inner bottom surface of the housing, and a protective component provided on the inner bottom surface of the housing, the protective component comprising:

[0007] The motor is fixedly connected to the inner bottom surface of the housing, and a bidirectional lead screw is fixedly connected to the output end of the motor. A clamping plate is threaded to the side wall of the bidirectional lead screw.

[0008] A crossbar is provided, an arc-shaped plate is fixedly connected to the side wall of the clamping plate, a mounting platform is fixedly connected to the side wall of the clamping plate, an elastic telescopic rod is fixedly connected to the top end face of the mounting platform, and the crossbar is fixedly connected to the top end face of the elastic telescopic rod.

[0009] A transparent cover is hinged to the top end face of the housing.

[0010] Preferably, an elastic element is fixedly connected to the inner wall of the arc-shaped plate, and a flexible arc plate is fixedly connected to the end of the elastic element away from the arc-shaped plate.

[0011] Preferably, the number of clamping plates is provided in two sets, and the two sets of clamping plates are symmetrically arranged on the side wall of the bidirectional lead screw.

[0012] Preferably, the side wall of the clamping plate has a semi-circular opening, and the inner wall of the semi-circular opening is flush with the inner wall of the arc plate, so that the cylindrical workpiece can be clamped by the arc plate on the two sets of clamping plates.

[0013] Preferably, the crossbar is flush with the top end face of the clamping plate, the crossbar is located between the arc-shaped plate and the clamping plate, and the crossbar supports the plate-shaped workpiece.

[0014] Preferably, there are two sets of motors and bidirectional lead screws, which are symmetrically arranged on both sides of the placement seat. The two sets of bidirectional lead screws are threadedly connected to the clamping plates. The motor drives the bidirectional lead screws to rotate, thereby causing the two sets of clamping plates to move longitudinally.

[0015] Compared with the prior art, this utility model provides an arc-drawing machine with a trigger-type protection structure, which has the following beneficial effects:

[0016] 1. This arc-drawing machine with a trigger-type protective structure uses clamping plates, arc-shaped plates, and crossbars, with a transparent cover to shield the shell and prevent the splashing of high-temperature metal particles. The cylindrical workpiece is clamped by two sets of arc-shaped plates, and if the workpiece is plate-shaped, it is clamped by two sets of clamping plates. The elastic telescopic rod pushes the crossbar downward, and the crossbar supports the plate-shaped workpiece. If the workpiece is cylindrical, the workpiece presses down on the crossbar. Through the elastic deformation of the elastic telescopic rod, the crossbar reverses to improve the stability of the clamping of the cylindrical workpiece, preventing the workpiece from sliding or shaking during processing.

[0017] 2. This arc-drawing machine with a trigger-type protective structure uses a flexible arc plate and elastic elements. The elastic elements push the flexible arc plate to tightly abut against columnar workpieces of different sizes. The flexible arc plate fits against the outer surface of columnar workpieces of different shapes, further enhancing the applicability of the equipment and avoiding the problem of unstable clamping caused by inconsistent workpiece sizes.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: an arc-drawing machine with a trigger-type protective structure, including a machine body 1, a shell 2 fixedly connected to the side wall of the machine body 1, a placement seat 3 fixedly connected to the inner bottom surface of the shell 2, and a protective component 4 provided on the inner bottom surface of the shell 2. The protective component 4 includes a motor 401, a bidirectional lead screw 402, a clamping plate 403, an arc plate 404, a mounting platform 405, an elastic telescopic rod 406, a crossbar 407, and a transparent cover 408.

[0025] In one embodiment of this utility model, a motor 401 is fixedly connected to the inner bottom surface of the housing 2. A bidirectional lead screw 402 is fixedly connected to the output end of the motor 401. A clamping plate 403 is threadedly connected to the side wall of the bidirectional lead screw 402. Two sets of clamping plates 403 are provided, and the two sets of clamping plates 403 are symmetrically arranged on the side wall of the bidirectional lead screw 402. Two sets of motor 401 and bidirectional lead screw 402 are provided, and the two sets of motor 401 and bidirectional lead screw 402 are symmetrically arranged on both sides of the placement base 3. The two sets of bidirectional lead screws 402 are threadedly connected to the clamping plates 403. The motor 401 drives the bidirectional lead screw 402 to rotate, thereby causing the two sets of clamping plates 403 to move longitudinally.

[0026] An arc-shaped plate 404 is fixedly connected to the side wall of the clamping plate 403. A semi-circular opening is provided on the side wall of the clamping plate 403. The inner wall of the semi-circular opening is flush with the inner wall of the arc-shaped plate 404, so that the cylindrical workpiece can be clamped by the arc-shaped plates 404 on the two sets of clamping plates 403. A mounting platform 405 is fixedly connected to the side wall of the clamping plate 403. An elastic telescopic rod 406 is fixedly connected to the top end face of the mounting platform 405. A crossbar 407 is fixedly connected to the top end face of the elastic telescopic rod 406. The crossbar 407 is flush with the top end face of the clamping plate 403. The crossbar 407 is located between the arc-shaped plate 404 and the clamping plate 403. The crossbar 407 supports the plate-shaped workpiece.

[0027] A transparent cover 408 is hinged to the top end face of the housing 2.

[0028] The workpiece is placed on the placement seat 3. The motor 401 starts and drives the bidirectional lead screw 402 to rotate, which in turn causes the clamping plate 403 to move toward the workpiece. If the workpiece is cylindrical, it is clamped by two sets of arc plates 404. If the workpiece is plate-shaped, it is clamped by two sets of clamping plates 403. The elastic telescopic rod 406 pushes the crossbar 407 downward, and the crossbar 407 supports the plate-shaped workpiece. If the workpiece is cylindrical, it presses the crossbar 407 downward. Through the elastic deformation of the elastic telescopic rod 406, the crossbar 407 reverses and improves the stability of the clamping of the cylindrical workpiece, preventing the workpiece from sliding or shaking during processing. Finally, the transparent cover 408 is used to cover the shell 2 to prevent the splashing of high-temperature metal particles and improve the safety of arc drawing operations.

[0029] In addition, an elastic element 5 is fixedly connected to the inner wall of the arc plate 404, and a flexible arc plate 6 is fixedly connected to the end of the elastic element 5 away from the arc plate 404. The flexible arc plate 6 fits against the outer surface of columnar workpieces of different shapes. Then, the elastic element 5 pushes the flexible arc plate 6 to tightly abut against columnar workpieces of different sizes, further enhancing the applicability of the equipment and avoiding the problem of unstable clamping caused by inconsistent workpiece sizes.

[0030] In this utility model, when in use, the workpiece is placed on the placement seat 3, the motor 401 drives the bidirectional lead screw 402 to rotate, causing the clamping plate 403 to move toward the workpiece and clamp it. The elastic element 5 pushes the flexible arc plate 6 to tightly abut against the columnar workpieces of different sizes. Then, the transparent cover 408 is used to cover the shell 2 to prevent the splashing of high-temperature metal particles.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
