Description

Technical Field

[0001] This utility model relates to a pipe marking device, belonging to the technical field of pipe machining equipment. Background Technology

[0002] During pipe processing, in order to achieve the corresponding functions, process points or process holes are usually machined on the surface of the pipe. These process points may provide technical effects such as increasing friction, providing corresponding markings, or facilitating installation. Traditionally, the processing of these process points is mainly carried out by manually placing the pipe on the corresponding mold and then stamping it. This method of operation is not conducive to multi-point processing along the pipe, as it may lead to uneven marking. In addition, it is not conducive to continuous processing, because manually confirming the marking position is time-consuming, which is not conducive to improving the efficiency and accuracy of marking work. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a pipe marking device for automatically marking the surface of pipes. The uniformity of the marking can be greatly improved. The device marks the pipes automatically, eliminating the need for manual judgment of the marking position, which helps to improve the marking efficiency.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] This utility model provides a pipe marking device, including a machine base, a placement platform horizontally slidably disposed on the machine base, a clamping device for clamping the pipe on the placement platform, a first driving member for driving the placement platform to move horizontally along its sliding direction on the machine base, and a marking assembly on the machine base. The marking assembly includes at least a positioning bracket and a second driving member disposed on the positioning bracket. A marking punch is installed on the connector at the output end of the second driving member. The first driving member is used to move the pipe to the working position of the marking punch, and the second driving member is used to drive the marking punch to mark the surface of the pipe.

[0006] Specifically, the placement platform is also provided with a rotating mechanism for driving the pipe to rotate on the clamping assembly. The clamping assembly is a pneumatic spindle chuck. The rotating mechanism includes a motor and a pulley assembly located at the output end of the motor. The pulley assembly is used to drive the pulley located at the end of the pneumatic spindle chuck to rotate.

[0007] Specifically, there are two second driving components, which are respectively located on opposite sides of the positioning bracket, and there are two dotting punches, which are respectively fixedly located at the output end of the corresponding second driving component.

[0008] Specifically, one of the punches has eight punching pins, and the other punch has nine punching pins.

[0009] Specifically, the dotting assembly also includes a lower pressure tool and an upper pressure tool. A third driving component is installed on the positioning bracket. The upper pressure tool is fixedly disposed at the output end of the third driving component. The third driving component is used to drive the upper pressure tool to press against the lower pressure tool. After pressing, a circular groove for pipes to pass through is formed between the upper and lower pressure tools.

[0010] Specifically, the upper presser is provided with a plurality of first arc grooves, and the lower presser is provided with a plurality of second arc grooves that correspond to the positions of the first arc grooves. The first arc grooves and the second arc grooves can form a complete circular hole after being joined together, and the circular hole can match the position of the punch.

[0011] Specifically, the first driving component includes a lead screw moving module horizontally arranged on the machine base, and the placement platform is fixedly arranged on the nut slider of the lead screw moving module.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0013] This utility model positions the pipe by setting corresponding clamping components on the machine base, and drives the pipe to move in the horizontal direction using the first driving component. At this time, the dotting mechanism is used to dot the surface of the pipe, which can realize the automatic conveying and continuous dotting of the pipe. This helps to ensure the uniformity of dotting and improve the efficiency of dotting, and provides a specific automatic dotting solution for the surface of pipe with a high degree of automation.

[0022] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0025] This utility model provides a pipe marking device for automatically marking the surface of pipes. The uniformity of the marking is significantly improved. The device automatically marks the pipes, eliminating the need for manual judgment of the marking positions, thus increasing marking efficiency. To realize the structural function of the device, it is configured as follows: the device includes a machine base 1, as shown... Figure 1 and Figure 2 As shown, specifically, a placement platform 2 is horizontally slidably mounted on the machine base 1, and a clamping assembly 3 for clamping the pipe is provided on the placement platform 2. The clamping assembly 3 shown can clamp pipes of various cross-sectional shapes, including but not limited to round pipes and square pipes. It can be a clamping surface composed of two clamping blocks or other clamping methods, as long as it can stably fix the pipe. In order to realize automatic marking work, a first driving component 4 is provided on the machine base 1 to drive the placement platform 2 to move horizontally along its sliding direction. Preferably, the first driving component 4 includes a lead screw moving module horizontally mounted on the machine base 1, and the placement platform 2 is fixedly mounted on the nut slider of the lead screw moving module. The lead screw is driven to rotate by a servo motor, so that the nut slider can drive the placement platform 2 to move precisely along its horizontal sliding direction. In addition to the range of motion required, the machine 1 is also equipped with a dotting component 5. The dotting component 5 includes at least a positioning bracket 501 and a second drive component 505 mounted on the positioning bracket 501. A dotting punch 507 is installed on the connector 506 at the output end of the second drive component 505. The dotting punch 507 can be a dotting pin with a small diameter. It achieves dotting work on the surface of the pipe through the squeezing or punching action of the second drive component 505. At this time, the first drive component 4 is used to move the pipe to the working position of the dotting punch 507, and then the second drive component 505 is used to drive the dotting punch 507 to dot the surface of the pipe. After the dotting work is completed, if it is necessary to continue dotting in the horizontal reverse direction, the placement table 2 can be pushed forward. Its uniformity can be well guaranteed.

[0026] This utility model provides a pipe marking device. In some special embodiments, if the customer needs to mark the pipe product evenly around its circumference, it will be difficult to mark different circumferential angle positions by simply horizontally conveying the pipe. Therefore, as a preferred technical solution, a rotating mechanism 6 for driving the pipe to rotate on the clamping assembly 3 is also provided on the placement table 2. Specifically, the clamping assembly 3 can be set as a pneumatic spindle chuck, and the rotating mechanism 6 includes a motor and a pulley assembly set at the output end of the motor. The pulley assembly is used to drive the pulley set at the end of the pneumatic spindle chuck to rotate. After the spindle chuck is started to clamp the pipe, the corresponding servo motor drives the pulley to rotate, thereby indirectly driving the pneumatic spindle chuck to rotate. After the pipe is marked at a certain rotation angle in the lateral direction, it can be rotated to other positions for re-marking, which is beneficial to meet the needs of different customers to process various types of marked pipes.

[0027] This utility model provides a pipe marking device. To improve the marking efficiency at multiple angles, it offers a technical solution capable of marking both sides of the pipe simultaneously. Specifically, it includes two second driving components 505, respectively positioned on opposite sides of a positioning bracket 501. Similarly, it includes two marking punches 507, each fixedly positioned at the output end of its corresponding second driving component 505. Figure 5 As shown, with this design, both sides are subjected to force simultaneously when marking points, avoiding the need for the other side to provide support. At the same time, marking points on both sides can be carried out at the same time, which can help improve marking efficiency.

[0028] This utility model provides a pipe marking device that, to meet specific customer requirements, has eight marking pins on one marking punch 507 and nine marking pins on another marking punch 507, thereby producing pipe products with the marking points.

[0029] This utility model provides a pipe marking device to prevent the pipe from shifting position during the marking process. Specifically, as shown in the example... Figure 5 As shown, the dotting assembly 5 can be configured to include a lower pressure plate 502 and an upper pressure plate 503. A third driving component 504 is mounted on the positioning bracket 501, and the upper pressure plate 503 is fixedly mounted on the output end of the third driving component 504. After the pipe passes through the middle position of the pressure plate, the third driving component 504 drives the upper pressure plate 503 to press against the lower pressure plate 502, thereby pressing and positioning the pipe to prevent the pipe from shifting during the dotting process. In order to ensure that the dotting bolt can pass through the pressure plate and be pressed against the surface of the pipe, a circular groove for the pipe to pass through is formed between the upper pressure plate 503 and the lower pressure plate 502 after pressing.

[0030] This utility model provides a pipe marking device, specifically a method for forming a circular groove. Specifically, the upper press 503 has multiple first arc grooves, and the lower press 502 has multiple second arc grooves that correspond to the positions of the first arc grooves. The first and second arc grooves can be joined together to form a complete circular hole 508 (i.e., a circular groove). The circular hole 508 can match the position of the marking punch 507. Through this design, the position of the circular hole 508 can accurately correspond to the position of the marking pin. The shape of the pipe can be restricted by the placement groove between the upper press 503 and the lower press 502, and it is not easy to cause large deformation, which is conducive to the smooth completion of the marking process of the pipe.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
