Description

Technical Field

[0001] This utility model relates to the field of pipe fitting production technology, and in particular to a pipe positioning frame for a marking machine. Background Technology

[0002] In oil drilling operations, resin-coated fiberglass pipes are widely used in various scenarios due to their excellent physical and chemical properties, such as corrosion resistance, lightweight, and high strength. For example, using high-performance resin-coated fiberglass pipes as oil pipelines solves the problem of easy corrosion of steel pipes.

[0003] During the production of resin fiberglass tubes, laser marking machines are usually used to mark some basic markings on the outer wall of the tubes, such as length and diameter.

[0004] Currently, when using a laser marking machine to mark the outer wall of pipe fittings, a positioning frame with a V-groove is usually placed on the marking machine's worktable. The pipe fitting is placed in the V-groove to support and limit its position, which is suitable for situations where the marking size range is small. However, in actual use, it is usually necessary to mark multiple sets of markings along the pipe fitting's axis to facilitate identification after the pipe is cut. Therefore, the existing positioning frame is difficult to meet the usage requirements. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the prior art that it is inconvenient to mark multiple sets of marks arranged along the axial direction on pipe fittings, and to propose a pipe positioning frame for a marking machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A marking machine pipe positioning frame includes a bracket and a sliding plate slidably disposed on the bracket. The sliding direction of the sliding plate is parallel to the axial direction of the pipe. A clamping part for clamping the pipe is fixedly disposed on the sliding plate, and a driving part for driving the sliding plate to slide is disposed on the bracket.

[0008] In order to guide the sliding plate during its sliding process, preferably, at least one set of guide rods is fixedly provided on the bracket, and the bottom of the sliding plate is slidably connected to the guide rods.

[0009] To facilitate the sliding of the sliding plate, the driving unit further includes a lead screw rotatably mounted on the bracket, the bottom of the sliding plate being threadedly connected to the lead screw, the axis of the lead screw being parallel to the axis of the guide rod, and a first motor for driving the lead screw to rotate being fixedly mounted at one end of the bracket.

[0010] To facilitate clamping of the pipe fitting, preferably, the clamping part includes a fixed seat fixedly mounted on the sliding plate, a three-jaw chuck for clamping the pipe fitting is rotatably mounted on the fixed seat, a first synchronous pulley is coaxially fixedly mounted on the three-jaw chuck, a second motor is fixedly mounted on the fixed seat, and a second synchronous pulley is fixedly mounted on the output end of the second motor, and the first synchronous pulley and the second synchronous pulley are driven by a toothed belt.

[0011] Furthermore, a support plate is slidably mounted on the sliding plate, and a pair of rotating frames are detachably mounted on the support plate. Support rollers for supporting the pipe are rotatably mounted on the rotating frames, and guide plates are fixedly mounted at both ends of the support plate. The inner walls of the two guide plates abut against the outer walls of the two sides of the sliding plate, and screws are threadedly connected to the guide plates. One end of the screw abuts against the side wall of the sliding plate, and a knob is fixedly mounted at the other end of the screw.

[0012] Preferably, support legs are fixedly provided at the bottom of both ends of the bracket, and adjustable feet are threaded to both ends of the support legs, and a level is fixedly provided on the sliding plate.

[0013] Compared with the prior art, this utility model provides a tube positioning frame for a marking machine, which has the following advantages:

[0014] 1. The marking machine's pipe positioning frame has a lead screw on the support for driving the sliding plate to slide. During marking, the sliding plate and pipe can slide along the axis of the lead screw to easily mark multiple sets of markings arranged along the axis of the pipe. Furthermore, by driving the three-jaw chuck to rotate the pipe, markings distributed along the circumference of the pipe can be marked, thus improving production efficiency.

[0015] 2. The marking machine's pipe positioning frame has a support plate that slides on a sliding plate. A pair of rotating frames are detachably mounted on the support plate. Support rollers for supporting pipes are rotatably mounted on the rotating frames. This design is suitable for supporting pipes of different lengths. By changing the rotating frames, pipes of different diameters can also be supported, thus improving the performance.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model, by setting a lead screw on the bracket for driving the sliding plate to slide, allows the sliding plate and pipe to slide conveniently along the axis of the lead screw during marking, thereby enabling multiple sets of markings arranged along the axis of the pipe to be marked, thus improving production efficiency.

[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 of the present utility model.

[0024] Example:

[0025] Reference Figures 1-4A marking machine pipe positioning frame includes a support 1, with support legs 102 fixedly installed at the bottom of both ends of the support 1, and adjustable feet 103 threadedly connected to both ends of the support legs 102, which can adjust the height of the support 1; it also includes a sliding plate 2 slidably installed on the support 1, with the sliding direction of the sliding plate 2 parallel to the axis of the pipe, a clamping part for clamping the pipe fixedly installed on the sliding plate 2, and a driving part for driving the sliding plate 2 to slide on the support 1. In use, by fixing one end of the pipe to the sliding plate 2 with the clamping part, setting the corresponding marking parameters, and starting the marking machine to mark, the sliding plate 2 and the pipe can be slid along the axis of the pipe by the starting driving part, so as to mark multiple sets of markings arranged along the axis of the pipe, thereby improving the production efficiency.

[0026] The adjustable support leg 103 can also adjust the level of the sliding plate 2 according to the changes in the usage site. In order to facilitate the inspection of the level of the sliding plate 2, a level is fixedly installed on the sliding plate 2. The bracket 1 and the support leg 102 are both assembled from aluminum profiles to form a structure similar to a long bench. When marking, it can be straddled on the marking machine to improve the usage effect.

[0027] In use, a lead screw 5 is provided on the bracket 1 to drive the sliding plate 2 to slide. During marking, the sliding plate 2 and the pipe can slide along the axis of the lead screw 5 to facilitate marking multiple sets of markings arranged along its axis on the pipe. Furthermore, by driving the three-jaw chuck 202 to rotate the pipe, markings distributed along its circumference can be marked on the pipe, improving production efficiency. A support plate 3 is slidably provided on the sliding plate 2, and a pair of rotating frames 4 are detachably provided on the support plate 3. A support roller 401 for supporting the pipe is rotatably provided on the rotating frames 4. This not only supports pipes of different lengths, but also allows for the support of pipes of different diameters by replacing the rotating frames 4, improving the overall performance.

[0028] Reference Figure 1 and Figure 2 At least one set of guide rods 101 are fixedly installed on the bracket 1. Here, we arrange two sets of guide rods 101 symmetrically. The bottom of the sliding plate 2 is slidably connected to the two sets of guide rods 101 respectively. In use, by fixing the guide rods 101 on the bracket 1, we can ensure that the sliding plate 2 slides reliably, reduce the occurrence of skew, and improve the marking quality.

[0029] Reference Figure 1 and Figure 2The drive unit can use a cylinder or an electric telescopic cylinder to drive the sliding plate 2 to slide. Here, we design the drive unit to have a lead screw 5 rotatably mounted on the bracket 1, and the bottom of the sliding plate 2 is threadedly connected to the lead screw 5. Moreover, the axis of the lead screw 5 is parallel to the axis of the guide rod 101. A first motor for driving the lead screw 5 to rotate is fixed at one end of the bracket 1. Both the first motor and the second motor are preferably servo motors. In use, by starting the first motor to rotate the lead screw 5, the sliding plate 2 can be driven to slide along the axis of the guide rod 101, thereby allowing the pipe to slide along its axial direction for marking, improving the usage effect.

[0030] Reference Figure 3 and Figure 4 Here, based on actual usage, we preferably design the clamping part as follows: a fixed base 201 is fixedly installed at the top of one end of the sliding plate 2; a three-jaw chuck 202 for clamping the pipe fitting is rotatably installed on the fixed base 201. The three-jaw chuck 202 is existing technology; here, we choose a manually adjustable three-jaw chuck 202. A first synchronous pulley 203 is coaxially fixedly installed at the end of the three-jaw chuck 202 away from the clamping pipe fitting; a second motor is fixedly installed on the fixed base 201; and a [missing information - likely a device or component] is fixedly installed at the output end of the second motor. The second synchronous pulley 204 drives the first synchronous pulley 203 and the second synchronous pulley 204 through a toothed belt, also called a synchronous belt. In use, a fixed seat 201 is fixedly set on the sliding plate 2, and a three-jaw chuck 202 is rotatably set on the fixed seat 201 to facilitate clamping of round or square tubes. Moreover, by starting the second motor, the second synchronous pulley 204 is rotated, and the toothed belt drives the first synchronous pulley 203 and the three-jaw chuck 202 to rotate, so as to adjust the marking direction along the circumference of the tube and improve the use effect.

[0031] Reference Figure 3 and Figure 4A support plate 3 is slidably mounted on the sliding plate 2. A pair of rotating frames 4 are detachably mounted on the support plate 3. Here, we preferably use bolts to fix the rotating frames 4 to the support plate 3. A support roller 401 for supporting the pipe is rotatably mounted on the rotating frame 4. Guide plates 301 are fixedly mounted at both ends of the support plate 3. The inner walls of the two guide plates 301 abut against the outer walls of the two sides of the sliding plate 2, which can limit and guide the support plate 3. Moreover, a screw is threadedly connected to each guide plate 301. One end of the screw is connected to the sliding plate 2. The side walls abut against each other, and a knob is fixedly installed at the other end of the screw. By rotating the knob, the screw rotates and abuts against the side wall of the sliding plate 2, thus restricting the support plate 3 to the current position. In use, the support plate 3 is slidably installed on the sliding plate 2, and a rotating frame 4 is detachably installed on the support plate 3. A support roller 401 for supporting the pipe is rotatably installed on the rotating frame 4. It can not only support pipes of different lengths, but also support pipes of different diameters by replacing the rotating frame 4, thus improving the use effect.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
