Description

Technical Field

[0001] This utility model relates to the field of gas cutting machine technology, and more specifically, to a semi-automatic gas cutting machine with an auxiliary positioning mechanism. Background Technology

[0002] The semi-automatic gas cutting machine body is made of high-strength alloy aluminum material by precision die casting. The cutting torch angle can be adjusted freely in front, back, left and right. It mainly uses straight line cutting. The use of semi-automatic cutting is still quite common in some small and medium-sized enterprises and even some large enterprises in my country.

[0003] A search revealed an existing patent (publication number: CN219188940U) disclosing a novel semi-automatic gas cutting machine, comprising a base, a support rail, and a gas cutting nozzle. The support rail is fixedly mounted on one side of the base, and the gas cutting nozzle is located above the support rail. A drive seat is slidably mounted on the top of the base, and a shaped rod is fixedly mounted on the top of the drive seat. A moving groove is formed on one side of the shaped rod, and a moving seat is slidably mounted in the moving groove. A limiting mechanism is provided between the moving seat and the moving groove. A rotating hole is formed on the inner wall of one side of the moving groove, and a drive mechanism is provided in the rotating hole and connected to the moving seat. A vertical plate is fixedly mounted on the other side of the moving seat, and a rectangular groove is formed on the top of the vertical plate. A rack plate is slidably mounted in the rectangular groove. This utility model has the following advantages and effects: it facilitates the adjustment of the gas cutting nozzle in the horizontal and vertical directions, thereby enabling the cutting of parts of different shapes and thicknesses. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing semi-automatic gas cutting machines still require manual operation due to the extremely strict requirements for metal cutting precision in many industries of modern manufacturing. Even experienced operators cannot avoid a certain degree of human error during operation, which affects the cutting size and product qualification rate. Furthermore, during normal operation, the gas cutting machine needs to move smoothly and linearly along the slide rail. Accidental collisions by the operator, vibrations of the machine itself, and impacts from the airflow can cause the gas cutting machine to lose its stable movement trajectory. Since there are no limiters to constrain its movement direction and range, it may deviate from the track, eventually leading to detachment and causing safety accidents.

[0005] Therefore, a semi-automatic gas cutting machine with an auxiliary positioning mechanism is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a semi-automatic gas cutting machine with an auxiliary positioning mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a semi-automatic gas cutting machine with an auxiliary positioning mechanism, comprising a base, an adjusting slide rail, a gas cutting machine body, a position pointer, and a sliding positioning rod. Support plates are provided on both sides of the upper surface of the base. The adjusting slide rails are respectively located at the front and rear of the upper surface of the base. Slide grooves are provided in the inner cavities of both sets of adjusting slide rails. A scale is provided on the front end face of one set of adjusting slide rails. The gas cutting machine body is mounted on the upper end of the two sets of adjusting slide rails. A rotating seat is installed at the center of the upper end of the gas cutting machine body. A movable column is installed at the upper end of the rotating seat. The rotating seat is connected to the movable column via a rotating shaft. A support rod passes through the upper end of the movable column. A gas cutting head is installed at the end of the support rod away from the movable column.

[0008] The position pointer is installed at the bottom of the front end of the gas cutting machine body. The sliding positioning rods are respectively set at the front and rear ends of the bottom of the gas cutting machine body. Nuts are installed on the outer surface of the sliding positioning rods. A handle is installed on the right side of the gas cutting machine body.

[0009] Preferably, the support plate is provided in four sets, and the two ends of the two sets of adjusting slide rails respectively abut against the two sets of support plates.

[0010] Preferably, the slide groove has a space for the sliding positioning rod to move, the inner surface of the slide groove abuts against the outer surface of the sliding positioning rod, and the sliding positioning rod engages with the nut after entering the two sets of slide grooves to achieve a limiting position.

[0011] Preferably, the gas cutting machine body moves linearly along the inner cavity of the two sets of sliding positioning rods, and a handle is installed on the right side of the gas cutting machine body.

[0012] Preferably, after rotating the nut away from the upper end of the sliding positioning rod, the distance between the nut and the bottom of the adjusting slide rail is adjusted.

[0013] Preferably, the position of the gas cutting machine body in the slide groove is moved, and the position pointer is adjusted to abut against the surface of the scale.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. Compared with the existing technology, the semi-automatic gas cutting machine with auxiliary positioning mechanism moves in the groove of the adjusting slide rail by sliding the positioning rod and is fixed by tightening the nut, so that the gas cutting machine body is precisely restricted to a specific position, which brings accurate and stable positioning to the gas cutting machine body. The operator can move the gas cutting machine body precisely according to the scale and determine the scale indicated by the position pointer, thereby assisting in achieving highly accurate positioning.

[0016] 2. Compared with the existing technology, the semi-automatic gas cutting machine with auxiliary positioning mechanism limits the gas cutting machine by sliding positioning rod and nut. Thus, when the position of the gas cutting machine body is adjusted, the sliding positioning rod and nut can still safely ensure the stable positioning of the gas cutting machine body, prevent slippage or tipping, and thus prevent it from accidentally falling off the slide rail.

[0022] 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.

[0023] Example 1

[0024] As attached Figures 1 to 4 The semi-automatic gas cutting machine with an auxiliary positioning mechanism shown includes a base 1, an adjusting slide rail 3, a gas cutting machine body 6, a position pointer 11, and a sliding positioning rod 12. Support plates 2 are provided on both sides of the upper surface of the base 1. The adjusting slide rails 3 are respectively located at the front and rear of the upper end of the base 1. The inner cavity of both sets of adjusting slide rails 3 is provided with a sliding groove 4. A scale 5 is provided on the front end face of one set of adjusting slide rails 3. The gas cutting machine body 6 is installed on the upper end of the two sets of adjusting slide rails 3. A rotating seat 7 is installed at the center of the upper end of the gas cutting machine body 6. A movable column 8 is installed on the upper end of the rotating seat 7. The rotating seat 7 is connected to the movable column 8 through a rotating shaft. A support rod 9 passes through the upper end of the movable column 8. A gas cutting head 10 is installed on the end of the support rod 9 away from the movable column 8.

[0025] The position pointer 11 is installed at the bottom of the front end of the gas cutting machine body 6, and the sliding positioning rods 12 are respectively set at the front and rear ends of the bottom of the gas cutting machine body 6. Nuts 13 are installed on the outer surface of the sliding positioning rods 12.

[0026] When using the gas cutting machine, the adjusting slide rail 3 and its inner cavity groove 4 provide a smooth and convenient movement path for the gas cutting machine body 6. The gas cutting machine body 6 can slide smoothly in the groove 4 with the help of the sliding positioning rod 12 at the bottom, allowing the gas cutting head 10 to be easily adjusted in the working area above the base 1. Whether it is for fine cutting of small parts or long-distance cutting of large plates, the operator only needs to gently push the handle 14, and the gas cutting machine body 6 can move stably along the groove 4, reducing the manpower consumption and operation difficulty when adjusting the gas cutting position, and greatly improving work efficiency. When the gas cutting machine body 6 moves to the predetermined position, tighten the nut 13 and abut it against the bottom of the adjusting slide rail 3, and the sliding positioning rod 12 will be firmly secured. The gas cutting head 10 is fixed in the groove 4, preventing it from shifting due to external factors. Even with vibration or external interference during the cutting process, this fixing method ensures that the gas cutting head 10 remains in the set position and angle. The rotating seat 7 is connected to the movable column 8 via a rotating shaft, allowing the movable column 8 to rotate flexibly on the rotating seat 7, thereby driving the gas cutting head 10 to change its angle. This enables the gas cutting machine to meet the cutting needs of various complex-shaped workpieces. The combination of the position pointer 11 and the scale 5 provides a precise position reference for gas cutting operations. When the operator moves the gas cutting machine body 6 through the handle 14, they can accurately determine the starting position and moving distance of the gas cutting head 10 relative to the workpiece based on the indication of the position pointer 11 on the scale 5.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0029] As a preferred embodiment, the support plate 2 is provided with four sets, and the two ends of the two sets of adjusting slide rails 3 respectively abut against the two sets of support plates 2; furthermore, the structure in which the four sets of support plates 2 abut against the two sets of adjusting slide rails 3 provides a stable frame for the gas cutting machine, and the weight of the gas cutting machine body 6 can be more evenly distributed through multi-point support.

[0030] In a preferred embodiment, the slide groove 4 has a space for the sliding positioning rod 12 to move. The inner surface of the slide groove 4 abuts against the outer surface of the sliding positioning rod 12. After the sliding positioning rod 12 enters the two sets of slide grooves 4, it engages with the nut 13 to achieve a limit. Furthermore, the slide groove 4 provides a precise movement guide for the sliding positioning rod 12. When the sliding positioning rod 12 abuts and moves in the slide groove 4, its movement trajectory is strictly limited and it can only move linearly along the direction of the slide groove 4.

[0031] In a preferred embodiment, the gas cutting machine body 6 moves linearly along the inner cavity of the two sets of sliding positioning rods 12 via two sets of sliding grooves 4 respectively, and a handle 14 is installed on the right side of the gas cutting machine body 6; furthermore, the handle 14, combined with the linear movement of the gas cutting machine body 6 in the sliding grooves 4 via the sliding positioning rods 12, greatly facilitates the operator's control of the gas cutting machine. By simply holding the handle 14, the operator can easily push or pull the two sets of sliding positioning rods 12 of the gas cutting machine body 6 to move along the sliding grooves 4.

[0032] In a preferred embodiment, after rotating the nut 13 away from the upper end of the sliding positioning rod 12, the distance between the nut 13 and the bottom of the adjusting slide rail 3 is adjusted; further, after loosening the nut 13 away from the sliding positioning rod 12 to remove the limit, the gas cutting machine body 6 can move freely, and the nut 13 will not be removed, thereby preventing the gas cutting machine body 6 from falling off the adjusting slide rail 3.

[0033] In a preferred embodiment, the gas cutting machine body 6 is moved to the position of the slide groove 4, and the position pointer 11 is adjusted to abut against the surface of the scale 5. Furthermore, the cooperation between the position pointer 11 and the scale 5 enables the position adjustment assistance of the gas cutting machine body 6 to achieve visual and precise positioning. When the operator moves the gas cutting machine body 6, he / she can intuitively observe the scale change of the position pointer 11 on the scale 5 to accurately determine the position of the gas cutting head 10.

[0034] The working process of this utility model is as follows: First, the gas cutting machine body 6 is placed on two sets of adjusting slide rails 3. Four sets of support plates 2 provide a stable support foundation for the entire equipment, ensuring that the adjusting slide rails 3 are in a horizontal and fixed state. When gas cutting is required, the operator, according to the cutting requirements and size of the workpiece, first rotates the nut 13 away from the upper end of the sliding positioning rod 12, thereby adjusting the distance between the nut 13 and the bottom of the adjusting slide rail 3, releasing the tight limit on the sliding positioning rod 12. Then, by holding the handle 14 on the right side of the gas cutting machine body 6, the operator uses the sliding positioning rod 12 to move linearly in the slide groove 4 inside the two sets of adjusting slide rails 3 to move the gas cutting machine body 6. During the movement, the operator observes the position pointer 11 at the bottom of the front end of the gas cutting machine body 6 in one set of adjusting slide rails. The position on the scale 5 on the front face of the rail 3 is used to accurately determine the starting position of the gas cutting head 10. After the position is determined, the nut 13 is rotated in the opposite direction to re-engage the sliding positioning rod 12, which firmly fixes the gas cutting machine body 6 in the corresponding position in the slide groove 4. At this time, the gas cutting machine body 6 will not be displaced by external force. According to the cutting requirements, the angle of the gas cutting head 10 can be flexibly adjusted by using the shaft connection between the rotating seat 7 and the movable column 8. By rotating the movable column 8 to make it rotate around the shaft, the support rod 9 and the gas cutting head 10 are driven to change the angle direction to adapt to the cutting angle requirements of different shaped workpieces. The gas cutting head 10 cuts the workpiece by connecting to the external pipe and generating a high-temperature flame. The above is the working principle of a semi-automatic gas cutting machine with an auxiliary positioning mechanism.
