Description

Technical Field

[0001] This utility model relates to the field of fixing fixture technology, specifically a steel pipe fixing fixture for shipbuilding. Background Technology

[0002] Ships are means of transportation that can navigate or anchor in waterways for transport or operations. They have different technical performance, equipment and structural types depending on the different usage requirements. When ships are built, ventilation, water supply and other piping systems require a large number of steel pipes, which often need to be temporarily positioned and fixed for cutting, welding or alignment.

[0003] Existing steel pipe fixing fixtures used in shipbuilding have poor clamping stability. Therefore, some people have thought of setting a locking structure for the fixture to improve clamping stability. For example, Chinese utility model patent with announcement number CN222114309U discloses a steel pipe fixing fixture for shipbuilding.

[0004] However, in actual use, it is found that the steel pipe fixing fixture used in shipbuilding uses two concave blocks to press the steel pipe together. However, after pressing, the steel pipe is difficult to rotate and it is not convenient to change other machined surfaces of the steel pipe. Utility Model Content

[0005] The purpose of this utility model is to provide a steel pipe fixing fixture for shipbuilding, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe fixing fixture for shipbuilding, comprising a first clamping assembly and a second clamping assembly.

[0007] The first clamping assembly includes a base, a bidirectional lead screw, a support plate, and a U-shaped frame. A groove is formed on the top of the base, and the bidirectional lead screw is rotatably connected within the groove. Two lead screw sliders are symmetrically threaded onto the bidirectional lead screw, and a support plate is fixed above each lead screw slider. The U-shaped frame is rotatably connected to the opposite surfaces of the two support plates. Rotating the bidirectional lead screw drives the two lead screw sliders closer together, and then the lead screw sliders move the support plate and the U-shaped frame. The steel pipe is fixed inside the U-shaped frame. After fixing, the U-shaped frame can rotate on the support plate, allowing the steel pipe to rotate and change the processing surface.

[0008] The second clamping assembly includes a telescopic motor and a clamping plate. The telescopic motor is fixed to both sides of the U-shaped frame, and the output end of the telescopic motor is fixed to the clamping plate. After clamping the steel pipe using the first clamping assembly, the telescopic motor is used to push the clamping plate to clamp the steel pipe again, thereby improving the fixing effect.

[0009] In a preferred embodiment of this invention, the back of the support plate is provided with a limiting plate and a fixing plate. The limiting plate is connected to the U-shaped frame via a rotating shaft, and the fixing plate is fixed to the support plate. Several positioning holes are provided on the outer side of the limiting plate, and a through screw hole is provided on the fixing plate. A locking bolt is connected to the screw hole, and the end of the locking bolt is inserted into the positioning hole to fix the limiting plate. When the U-shaped frame rotates, the connecting rotating shaft drives the limiting plate to rotate together. After rotating to the required angle, the locking bolt is used to lock and fix the limiting plate.

[0010] In a preferred embodiment of this invention, a drive motor is fixed to the end of the slide groove, and the drive shaft of the drive motor is connected to a bidirectional lead screw, thereby driving the bidirectional lead screw through the drive motor. Manual rotation is also possible.

[0011] In a preferred embodiment of this invention, the lead screw and the slide groove are connected by a sliding connection, with the slide groove used to restrict the lead screw and the slide groove.

[0012] As a preferred embodiment of this invention, the clamping plate is arc-shaped to fit the steel pipe.

[0013] As a preferred embodiment of this utility model, the base has a mounting hole at the corner, which is used to fix the device.

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

[0015] This utility model improves the fixing effect of steel pipe by setting a first clamping component and a second clamping component to fix the steel pipe. The U-shaped frame can be rotated, so that the steel pipe can be rotated after being fixed, so as to facilitate the processing of other surfaces.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a steel pipe fixing fixture for shipbuilding, including a first clamping component and a second clamping component.

[0025] The first clamping assembly includes a base 1, a bidirectional lead screw 2, a support plate 4, and a U-shaped frame 5. A groove 101 is formed on the top of the base 1. The bidirectional lead screw 2 is rotatably connected within the groove 101. Two lead screw sliders 201 are symmetrically threaded onto the bidirectional lead screw 2. A support plate 4 is fixed above each lead screw slider 201. The U-shaped frame 5 is rotatably connected to the opposite surfaces of the two support plates 4. By rotating the bidirectional lead screw 2, the two lead screw sliders 201 are driven to move closer together. Then, the lead screw sliders 201 drive the support plate 4 and the U-shaped frame 5 to move. The steel pipe is fixed inside the U-shaped frame 5. After fixing, the U-shaped frame 5 can rotate on the support plate 4, allowing the steel pipe to rotate and change the processing surface.

[0026] The second clamping assembly includes a telescopic motor 6 and a clamping plate 7. The telescopic motor 6 is fixed to both sides of the U-shaped frame 5, and the output end of the telescopic motor 6 is fixed to the clamping plate 7. After clamping the steel pipe using the first clamping assembly, the telescopic motor 6 is used to push the clamping plate 7 to clamp the steel pipe again, thereby improving the fixing effect.

[0027] Furthermore, a limiting disc 8 and a fixing plate 9 are provided on the back of the support plate 4. The limiting disc 8 is connected to the U-shaped frame 5 via a rotating shaft, and the fixing plate 9 is fixed to the support plate 4. Several positioning holes 801 are provided on the outer side of the limiting disc 8, and a through screw hole is provided on the fixing plate 9. A locking bolt 10 is connected to the screw hole, and the end of the locking bolt 10 is inserted into the positioning hole 801 to fix the limiting disc 8. When the U-shaped frame 5 rotates, it drives the limiting disc 8 to rotate together through the connected rotating shaft. After rotating to the required angle, the limiting disc 8 is locked and fixed by the locking bolt 10.

[0028] Furthermore, a drive motor 3 is fixed to the end of the slide groove 101, and the drive shaft of the drive motor 3 is connected to the bidirectional lead screw 2, thereby driving the bidirectional lead screw 2 through the drive motor 3. Manual rotation can also be used.

[0029] Furthermore, the lead screw slider 201 and the slide groove 101 are slidably connected, and the slide groove 101 is used to restrict the lead screw slider 201.

[0030] Furthermore, the clamping plate 7 is arc-shaped to accommodate the steel pipe.

[0031] Furthermore, a mounting hole 102 is provided at the corner of the base 1, and the mounting hole 102 is used to fix the device.

[0032] In summary, when using this device, the steel pipe is placed between the two support plates 4, and then the bidirectional lead screw 2 is rotated, causing the two lead screw sliders 201 to move closer together. The lead screw sliders 201 move the support plates 4, which in turn move the U-shaped frame 5 closer to and clamp the steel pipe. After clamping, the telescopic motor 6 is started, causing the telescopic motor 6 to push the clamping plate 7, which clamps the steel pipe again, allowing for processing of the steel pipe. During the process, if it is necessary to rotate the steel pipe, simply rotate the locking bolt 10 to unscrew it from the positioning hole 801. Then, the U-shaped frame 5 can be rotated, causing the U-shaped frame 5 to rotate the steel pipe and the limiting disc 8. After rotating to the desired surface, the locking bolt 10 is screwed back into the corresponding positioning hole 801.

[0033] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0034] 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.
