Description

Technical Field

[0001] This utility model relates to the field of gas cutting machine track technology, specifically a track for a semi-automatic gas cutting machine. Background Technology

[0002] A semi-automatic gas cutting machine is a device that uses medium-pressure gas (such as propane) and high-pressure oxygen for cutting. It is mainly used for cutting steel plates thicker than 5 mm and can perform straight cuts, circular cuts, bevel cuts, and V-cuts. Under normal circumstances, the cut workpiece does not require further machining. The semi-automatic gas cutting machine is mainly used by setting up a track to meet the needs of moving and cutting.

[0003] A search revealed patent application CN202020009287.5, which discloses a semi-automatic gas cutting machine track. The track includes a gas cutting machine body and a slide rail. The slide rail includes longitudinal rails, the top of which is adapted to a pulley at the bottom of the gas cutting machine body. One end of each longitudinal rail has a protrusion, and the other end has a groove that matches the protrusion. The number of longitudinal rails is greater than two, and the protrusion on one longitudinal rail engages with the groove on another. This semi-automatic gas cutting machine track utilizes multiple segments of longitudinal rails joined together. Each segment has a protrusion and a groove at both ends. The protrusion on one segment engages with the groove on another segment, and the two ends of the longitudinal rails are fixed by connecting components. These segments are sequentially connected end-to-end to form a complete track for the gas cutting machine to slide on. For transport, the entire track is further divided into multiple segments for easier carrying.

[0004] However, this patent has its shortcomings. In actual use, the semi-automatic gas cutting machine track is prone to derailment during the sliding process of the semi-automatic gas cutting machine body due to the lack of a limiting structure between the pulley and the longitudinal rail, which affects the normal cutting use of the semi-automatic gas cutting machine.

[0005] Therefore, we propose a track for a semi-automatic gas cutting machine. Utility Model Content

[0006] The purpose of this invention is to provide a track for a semi-automatic gas cutting machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a track for a semi-automatic gas cutting machine, comprising a base plate and a pulley mechanism. The pulley mechanism includes balls, support wheels, and sliding shafts. Each sliding shaft has a support wheel fixedly installed at its front and rear ends. Two support wheels are rotatably connected to each other on one side. A vertical frame is fixedly installed on the base plate. Slide rails are fixedly installed on the base plate at the front and rear ends of the vertical frame. Limit grooves are provided in both slide rails. A threaded rod is rotatably connected in the vertical frame. A sliding seat is threaded onto the threaded rod. Multiple turntables are rotatably connected in the sliding seat at the front and rear parts of the threaded rod. A connecting shaft is fixedly installed on the side of the multiple turntables away from the sliding seat. A pulley mechanism is fixedly installed on the end of the multiple connecting shafts away from the sliding seat. The multiple sliding shafts are rotatably connected in corresponding limit grooves.

[0008] Optionally, a limiting plate is engaged on the left side of each of the two slide rails, and a bearing sleeve is fixedly installed on the right side of the limiting plate. The left end of the threaded rod is rotatably connected to the bearing sleeve, and the bearing sleeve can support and limit the left end of the threaded rod.

[0009] Optionally, a connecting plate is fixedly installed on the right side of the limiting plate, and a fixing bolt is internally threaded onto the connecting plate. The bottom end of the fixing bolt extends into the base plate, and the limiting plate can be fixed and limited by the fixing bolt.

[0010] Optionally, the limiting plate is configured as a cross shape, and both the front and rear ends of the limiting plate extend into the corresponding limiting grooves. This design is beneficial to the use of the device.

[0011] Optionally, a forward and reverse motor is fixedly installed on the right side of the upright frame. The output end of the forward and reverse motor is fixedly installed on the threaded rod. The forward and reverse motor drives the threaded rod to rotate, which is beneficial to the use of this equipment.

[0012] Optionally, the forward and reverse motors are electrically connected to an external PLC controller via connecting wires, which is beneficial for the use of this equipment.

[0013] Optionally, a mounting plate is fixedly installed on the top of the slide block. The top of the mounting plate has multiple threaded holes, which facilitate the fixing of the semi-automatic gas cutting machine onto the mounting plate using external bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Through the cooperation of ball bearings, support wheels, sliding shafts, fixing bolts, limit plates, threaded rods, bearing sleeves, uprights, turntables, and connecting shafts, multiple support wheels and slide rails can be limited during the sliding process of the slide block, preventing derailment. At the same time, the pulley mechanism and slide rails can be quickly disassembled and assembled, which is beneficial for subsequent maintenance and replacement. Furthermore, the pulley mechanism has the advantages of low friction and long service life. 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] Please see Figures 1 to 4This utility model provides a track for a semi-automatic gas cutting machine, including a base plate 1 and a pulley mechanism 4. The pulley mechanism 4 includes ball bearings 401, support wheels 402, and sliding shafts 403. Each sliding shaft 403 has a support wheel 402 fixedly installed at its front and rear ends. Two support wheels 402 are rotatably connected to each other on one side. A stand 3 is fixedly installed on the base plate 1. Slide rails 2 are fixedly installed on the base plate 1 at the front and rear ends of the stand 3. Each slide rail 2 is provided with a limit groove 12. A threaded rod 13 is rotatably connected in the stand 3. A slide seat 9 is threadedly fitted on the threaded rod 13. Multiple turntables 14 are rotatably connected in the slide seat 9 at the front and rear ends of the threaded rod 13. A connecting shaft 15 is fixedly installed on the side of the multiple turntables 14 away from the slide seat 9. The pulley mechanism 4 is fixedly installed on the end of the multiple connecting shafts 15 away from the slide seat 9. Multiple sliding shafts 403 are rotatably connected in the corresponding limit grooves 12.

[0023] A limiting plate 8 is engaged on the left side of each of the two slide rails 2. A bearing sleeve 11 is fixedly installed on the right side of the limiting plate 8. The left end of the threaded rod 13 is rotatably connected to the bearing sleeve 11, which supports and limits the left end of the threaded rod 13. A connecting plate 6 is fixedly installed on the right side of the limiting plate 8, and a fixing bolt 7 is threaded into the connecting plate 6. The bottom end of the fixing bolt 7 extends into the base plate 1, which fixes and limits the limiting plate 8. The limiting plate 8 is cross-shaped, and both its front and rear ends extend into the corresponding limiting grooves 12. This design is beneficial to the use of this equipment. A forward and reverse motor 10 is fixedly installed on the right side of the upright frame 3. The output end of the forward and reverse motor 10 is fixedly installed on the threaded rod 13. The forward and reverse motor 10 drives the threaded rod 13 to rotate, which is beneficial to the use of this equipment. The forward and reverse motor 10 is electrically connected to an external PLC controller through a connecting wire. This design is beneficial to the use of this equipment. A mounting plate 5 is fixedly installed on the top of the slide 9. Multiple threaded holes are reserved on the top of the mounting plate 5. The multiple threaded holes facilitate the fixing of the semi-automatic gas cutting machine on the mounting plate 5 with external bolts.

[0024] Working Principle: During use, the semi-automatic gas cutter is fixedly mounted on the mounting plate 5 using multiple external bolts and threaded holes. Then, the forward rotation switch of the forward / reverse motor 10 is turned on. The motor 10 drives the threaded rod 13 to rotate forward. At this time, the slide block 9 drives the mounting plate 5 and the semi-automatic gas cutter to slide to the left, thus enabling the semi-automatic gas cutter to perform moving cutting operations. During the movement, multiple sliding shafts 403 are slidably connected within the limiting grooves 12, which can limit the multiple support wheels 402. Simultaneously, the threaded rod 13 limits the slide block 9, thereby preventing the slide block 9 from derailing. Multiple ball bearings 401 are rolled along the slide rail 2 on the side closest to it, reducing friction during sliding and minimizing support. Wear on the side of wheel 402 extends its service life. When the pulley mechanism 4 needs maintenance, the fixing bolt 7 can be unscrewed and removed. At this time, the limiting plate 8 loses its limit. Pull the limiting plate 8 to the left to separate the limiting plate 8 from the two slide rails 2, so that the slide 9 and multiple pulley mechanisms 4 can slide out of the two slide rails 2, making it convenient for replacement and maintenance. This type of semi-automatic gas cutting machine track is easy to use. Through the above components, multiple support wheels 402 can be limited between the slide rails 2 during the sliding of the slide 9, avoiding derailment during the sliding process. At the same time, the pulley mechanism 4 can be quickly disassembled and assembled from the slide rails 2, which is beneficial for subsequent maintenance and replacement. Moreover, the pulley mechanism 4 has the advantages of low friction and long service life.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
