Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically a steel pipe chamfering machine. Background Technology

[0002] Chamfering welding of steel pipes is a common metal connection method, mainly used to connect and seal steel pipes. Chamfering refers to cutting the end face of the steel pipe into a bevel at a certain angle to facilitate better fusion during welding. Commonly used welding methods include electric arc welding and gas shielded welding. Before chamfering welding of steel pipes, preparation work needs to be done on the joint, including cleaning the joint surface and ensuring the geometric shape and dimensional accuracy of the joint. During the welding process, welding parameters such as current, voltage, and welding speed also need to be controlled to ensure welding quality and joint strength.

[0003] For example, a Chinese patent (publication number: CN212444490U) discloses a chamfering machine for steel pipe processing, comprising a machine body, a fixed block, and a movable block. The fixed block is provided on the upper left side of the machine body, and a fixed mounting groove is installed on the right side of the fixed block. The movable block is provided on the upper right side of the machine body, and a fixed groove is connected to the left side of the movable block. A chamfering grinding head is provided at the right end of the fixed groove. A motor is installed on the movable block, and a base is provided below the motor. A groove is opened on the upper right side of the machine body, and a locking rod is provided on the groove. A locking block is provided on the outer side of the locking rod. A first sliding groove is provided on the machine body, and a second sliding groove is opened on the inner side of the first sliding groove. A pulley is connected to the second sliding groove. This utility model, by fixing the motor on the movable block, can easily drive the motor to move when the movable block moves, thereby cooperating with the chamfering to rotate and chamfer the steel pipe.

[0004] This patent uses a clamping mechanism formed by clamping rods and clamping blocks to achieve chamfering of steel pipes of different lengths by adjusting the different clamping positions of the moving blocks. However, the clamping mechanism is not conducive to grinding and chamfering different positions of the steel pipe, resulting in poor performance. Therefore, a steel pipe chamfering machine is proposed to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0030] 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.

[0031] Please see Figures 1 to 3In this embodiment, a steel pipe chamfering machine includes a housing 1 and a movable box 7. The back of the housing 1 is hinged with an opening and closing door, and the front of the housing 1 is fixed with a collection box 2. The collection box 2 includes a box body 201, a movable door 202, and a handle 203. The box body 201 is fixed to the front of the housing 1 and the bottom of the control console 3. The connecting pipe 4 is connected to the box body 201. The movable door 202 is hinged to the front of the box body 201, and the handle 203 is fixed to the front of the movable door 202.

[0032] Understandably, the opening and closing door facilitates the opening of the outer casing 1, allowing the movable box 7 to be moved out of the device. The control console 3 facilitates the drive control of the entire device, enabling convenient adjustment and control of the cutting tools. It also facilitates the collection of dust and impurities inside the device, preventing contamination caused by chamfering machine processing, improving the stability of the device, and enhancing the overall ease of use through flexible tool adjustment.

[0033] It should be noted that the top of the collection box 2 is fixed with a control console 3 fixed to the front of the outer shell 1, the top of the outer shell 1 is fixed with a protective shell 5, the front of the protective shell 5 is connected with a connecting pipe 4 that passes through the control console 3 and connects to the collection box 2, a connecting plate 6 is fixed between the inner walls of the outer shell 1, the top of the connecting plate 6 is provided with a recycling port, the bottom of the connecting plate 6 is fixed with a recycling plate that is concentrically arranged with the recycling port, and the movable box 7 is located at the bottom of the recycling plate.

[0034] It is also understandable that the connection pipe 4 facilitates control via the control console 3 and the collection of dust inside the protective shell 5, thereby preventing pollution during device use and improving the stability of device operation. The recycling plate facilitates the limited recovery of impurities from grinding and cutting, thereby improving the environmental friendliness of the device and enhancing the overall performance.

[0035] It should also be noted that a placement cylinder 8 is fixed on the inner wall of the left side of the outer shell 1, a movable cover is hinged to the front of the protective shell 5, an observation window is embedded in the front of the movable cover, a placement opening communicating with the placement cylinder 8 is opened on the left side of the protective shell 5, a stabilizing plate 9 fixed to the outside of the placement cylinder 8 is fixed to the top of the connecting plate 6, a three-jaw chuck 10 is fixed to the right side of the placement cylinder 8, a connecting plate 11 fixed to the top of the connecting plate 6 is fixed to the outside of the three-jaw chuck 10, and a displacement mechanism 12 is provided on the top of the connecting plate 6.

[0036] It should be noted that the movable cover facilitates the opening and closing of the protective shell 5, which in turn facilitates the replacement and adjustment of the cutting tools and the convenient use of the device. The placement port facilitates the placement of the steel pipe, which in turn facilitates the stable use of the device. The three-jaw chuck 10 facilitates the clamping of the steel pipe, which in turn improves the stability of the device.

[0037] Please see Figure 4 To improve flexibility, the displacement mechanism 12 in this embodiment includes a base plate 1201, a drive motor 1202, a rotating rod 1203, a fixed platform 1204, a limiting strip 1205, a moving block 1206, and an actuating mechanism. The base plate 1201 is fixed to the top of the connecting plate 6, the drive motor 1202 is fixed to the top of the connecting plate 6, the rotating rod 1203 is fixed to the output shaft of the drive motor 1202, the fixed platform 1204 is fixed to the top of the base plate 1201, the limiting strip 1205 is fixed to the top of the fixed platform 1204, the moving block 1206 is slidably connected to the outer side of the limiting strip 1205, a sliding channel is provided on the top of the moving block 1206, and the moving block 1206 is slidably connected to the outer side of the limiting strip 1205 through the sliding channel. The top of the moving block 1206 is fixed to the actuating mechanism, and the actuating mechanism is threadedly connected to the rotating rod 1203.

[0038] It should also be noted that the sliding channel facilitates the stable sliding of the moving block 1206. Through the limiting effect of the limiting strip 1205, the drive motor 1202 drives the rotating rod 1203 to rotate. Through the threaded connection between the rotating rod 1203 and the threaded block, the moving block 1206 is displaced, thereby driving the moving table 1207 to move, and then driving the cutter to move back and forth, which improves the flexibility of the device.

[0039] It can be observed that the operating mechanism includes a movable stage 1207, a rotary motor 1208, a rotating rod 1209, a fixed bar 1210, a movable block 1211, and a tool holder 1212. The movable stage 1207 is threadedly connected to the outer side of the rotating rod 1203. The movable stage 1207 is fixed to the top of the movable block 1206. The rotary motor 1208 is fixed to the top of the movable block 1206. The rotating rod 1209 is fixed to the output shaft of the rotary motor 1208. The fixed bar 1210 is fixed to the top of the movable stage 1207. The movable block 1211 is slidably connected to the outer side of the fixed bar 1210. A moving channel is provided at the bottom of the movable block 1211.

[0040] It is easy to see that the setting of the moving channel facilitates the sliding displacement of the movable block 1211 and the fixed bar 1210, which in turn facilitates the power supply of the rotary motor 1208. Through the threaded connection between the movable block 1211 and the rotating rod 1209, and in conjunction with the limiting effect generated by the sliding of the movable block 1211 and the fixed bar 1210, the movable block 1211 is driven to move left and right along the fixed bar 1210, thereby further improving the flexibility of the overall device.

[0041] It can also be observed that the movable block 1211 is slidably connected to the fixed strip 1210 through the moving channel, the tool holder 1212 is fixed to the top of the movable block 1211, the bottom of the tool holder 1212 is threadedly connected to the outer side of the rotating rod 1209, the bottom of the moving table 1207 and the tool holder 1212 are both fixed with threaded blocks, and the moving table 1207 and the tool holder 1212 are threadedly connected to the rotating rod 1203 and the rotating rod 1209 respectively through threaded blocks.

[0042] In this embodiment, the threaded block facilitates the sliding displacement of the movable block 1211 and the moving block 1206 through the threaded connection of the rotating rod 1203 and the rotating rod 1209, thereby enabling the left, right, front, and back displacement of the cutter. This allows for cutting and grinding of different positions on the steel pipe, improving the chamfering effect of the device on the steel pipe and ultimately enhancing the overall performance of the device.

[0043] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0044] The working principle of the above embodiments is as follows:

[0045] Open the movable cover, identify the required cutting tool, and install the tool on the tool holder 1212. Insert the steel pipe into the placement cylinder 8 through the placement port, and then use the three-jaw chuck 10 to clamp and secure the steel pipe, ensuring processing stability. The circuit control system drives the three-jaw chuck 10 to rotate. By starting the drive motor 1202 and the rotary motor 1208, the rotating rod 1203 and the rotating rod 1209 are driven to rotate. Through the limiting action of the limit bar 1205 and the fixing bar 1210, the moving block 1206 is moved. The sliding of the movable block 1211 causes the tool holder 1212 to move, thereby adjusting the tool to different positions. Under the rotation of the steel pipe, the steel pipe is chamfered and ground, which is beneficial for chamfering. At the same time, the dust inside the protective shell 5 and the outer shell 1 is extracted through the connecting pipe 4 and transferred to the box 201. The impurities produced by grinding are recycled to the movable box 7 through the recycling plate, which helps to prevent pollution from processing. The whole device is convenient to use, highly adjustable, and has good performance.
