Description

Technical Field

[0001] This utility model relates to a suspended positioning fixture for long pipe fittings. Background Technology

[0002] Long pipes or other elongated workpieces typically require the machining of various holes and grooves on their surfaces. During machining, due to limited space within the CNC lathe, only a portion of the long pipe or other elongated workpiece can be placed and fixed, while the other end remains outside. Currently, this is achieved by stacking metal sheets to keep the outer and inner ends of the long pipe or other elongated workpiece level and fixed. This method has significant errors, is labor-intensive, and may result in tilting at the inner end, causing machining accuracy errors and affecting the yield rate. Therefore, improvement is urgently needed. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a suspended positioning fixture for long pipes, which is not only reasonable in structure, but also convenient and stable.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a long pipe suspension positioning fixture, including a support base, a V-shaped support groove is opened on the support base, the lower end of the support base is driven to rise and fall by a screw, a rocker arm is screwed to the outside of the screw, the rocker arm is rotatably connected to the lower support plate, a guide post is vertically fixed on the support plate and the guide post passes through the support base upward to limit the support base, and a support leg is fixed at the lower end of the support plate.

[0005] Furthermore, the support plate has a threaded hole in the middle for the screw to pass through, and a limiting sleeve with internal threads for screwing the screw is fixed at the bottom of the support plate at the threaded hole.

[0006] Furthermore, the support legs are symmetrically arranged in two sets, and each support leg has an adjusting plate fixedly connected to its bottom. The adjusting plate has several vertically opened screw holes and bolts are screwed into the screw holes. The lower end of the bolts passes through the adjusting plate and is fixedly connected to an adjusting block.

[0007] Furthermore, the lower end of the adjusting plate is provided with a receiving groove at the screw hole for storing the adjusting block.

[0008] Furthermore, a docking block is fixedly provided at the bottom of the support base, and the bottom of the docking block is recessed with a docking groove for the top of the docking screw.

[0009] Furthermore, the rocker arm includes a sleeve with a centrally located screw hole, and an annular handle is connected to the outside of the sleeve via several connecting rods.

[0010] Compared with the prior art, the present invention has the following advantages: the long pipe suspension positioning fixture lifts or lowers the long pipe at one end by rotating the rocker arm to adjust it to the same level as the other end and provides stable support, thereby completing the positioning of the suspended part of the long pipe and ensuring the accurate processing of the other end. The overall structure is simple, convenient and stable.

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0017] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0018] like Figures 1-4 As shown, the long pipe suspension positioning fixture includes a support base 1, on which a V-shaped support groove 2 is formed. The lower end of the support base is driven to rise and fall by a screw 3. A rocker arm 4 is screwed to the outside of the screw. The rocker arm is rotatably connected to the lower support plate 5 through a bearing. A guide post 6 is vertically fixed on the support plate and passes through the support base to limit the support base. The guide posts are all slidably connected to the support base. Two sets of guide posts are symmetrically arranged and pass through the V-shaped support groove. A support leg 7 is fixed at the lower end of the support plate.

[0019] In this embodiment of the utility model, a threaded hole 8 is provided in the middle of the support plate for the screw to pass through, and a limiting sleeve 9 with internal threads for screwing the screw is fixed at the bottom of the support plate at the threaded hole.

[0020] In this embodiment of the utility model, two sets of support legs are symmetrically arranged. Each support leg has an adjusting plate 10 fixedly connected to its bottom. The adjusting plate has several screw holes 11 vertically opened and bolts 12 are screwed into the screw holes. The lower end of the bolts passes through the adjusting plate and is fixedly connected to a leveling block 13.

[0021] In this embodiment of the utility model, the lower end of the adjusting plate is provided with a receiving groove 14 for storing the leveling blocks at the screw hole. That is, when the ground is flat, the leveling blocks are stored in the receiving groove. When the ground is uneven, the leveling blocks are moved down by rotating the bolts to level them.

[0022] In this embodiment of the utility model, a docking block 15 is fixedly provided at the bottom of the support base, and a docking groove 19 for docking the top of the screw is recessed at the bottom of the docking block to ensure that the screw stably supports the support base and avoids detaching from the support position.

[0023] In this embodiment of the utility model, the rocker arm includes a sleeve 16 with a screw hole in the center, and a ring-shaped handle 17 is connected to the outside of the sleeve by several connecting rods 18.

[0024] The working principle of this utility model embodiment is as follows: First, the device is placed in front of the long pipe processing device and leveled. Then, one end of the long pipe is locked in the processing device, and the other end is placed in the V-shaped support groove. Then, by rotating the rocker arm, the long pipe at one end is raised or lowered to adjust it to be at the same level as the other end and to provide stable support, thereby completing the positioning of the suspended part of the long pipe and ensuring the accurate processing of the other end.

[0025] This utility model is not limited to the preferred embodiment described above. Anyone can derive other forms of long pipe suspension positioning fixtures based on the teachings of this utility model. All equivalent variations and modifications made within the scope of the claims of this utility model shall fall within the scope of this utility model.
