Description

Technical Field

[0001] This utility model belongs to the field of movable elbow technology, and in particular, it is a movable elbow assembly fixture. Background Technology

[0002] In construction projects, various pipes are often required to transport water and other media, and elbows are needed to connect multiple pipes to each other.

[0003] The existing assembly fixture for movable elbows only clamps one end of the movable elbow during use. Due to the different sizes of movable elbows, there is a lack of support and fixation for the other output end of the movable elbow, which makes the movable elbow easy to fall off during assembly and reduces the efficiency of use.

[0004] A search revealed a Chinese patent document (authorization announcement number CN209793219U) regarding a positioning fixture for a movable elbow. This fixture uses a first positioning component to fix the bent portion of the movable elbow to a first mounting base, and a second positioning component to fix one end of the movable elbow to a second mounting base to achieve positioning of the movable elbow. The fixture is then machined using a lathe. However, this device has the following problem: during use, it cannot effectively fix both ends of elbows of different sizes simultaneously, making them prone to detachment during assembly and reducing efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling for assembling movable elbows to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a movable elbow assembly fixture, comprising: a base frame and a disc disposed on the upper end of the base frame; a first rotary motor is mounted on the vertical side of the disc, a cylinder is sleeved on the drive end of the first rotary motor, four sliding grooves are provided on the outer circumference of the cylinder, a third telescopic rod is mounted on the vertical inner wall of the cylinder, a cylinder is mounted on the moving part of the third telescopic rod, four connecting frames that fit against the inner wall of the sliding groove are fixed on the circumference of the cylinder, and four connecting frames with the same structure are fixed on the vertical inner wall of the sliding groove, a first telescopic rod is mounted on the inner wall of each of the eight connecting frames near the cylinder, and a second clamping ring for fixing the movable elbow is mounted on the moving part of each of the eight first telescopic rods;

[0007] The other side of each of the eight second clamping rings is attached to a first clamping ring. Each of the eight first clamping rings is equipped with a second telescopic rod on the side away from the cylinder, and the moving part of the second telescopic rod is fixed on the side of the second clamping ring closer to the first clamping ring.

[0008] In a further embodiment, a support base is fixed to the top of the bottom frame, and a linear motor is mounted on the vertical side of the support base.

[0009] In a further embodiment, a slider is installed at the drive end of the linear motor, and a connecting block that fits against the inner wall of the support base is fixed on the vertical side of the slider.

[0010] In a further embodiment, a groove is provided at the top of the connecting block, and a second rotary motor is installed on the vertical inner wall of the groove.

[0011] In a further embodiment, the drive end of the second rotary motor is connected to a vertical frame via a rotating rod, and the disc is fixed to the vertical side of the vertical frame.

[0012] In a further embodiment, four brackets mounted on the top of the bottom frame are fixed to the vertical side of the support base.

[0013] In a further embodiment, two base plates are fixed to the bottom end of the base frame, and two fixing seats are installed at the bottom end of each of the two base plates.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] This movable elbow assembly fixture utilizes a linear motor located on the vertical side of the support base to control the vertical displacement of the slider and connecting block, causing the vertical frame to move synchronously. During the movement, the height of the assembly structure is adjusted. Simultaneously, a second rotary motor located in the groove controls the rotation of the vertical frame to adjust the angle of the assembly structure, thus facilitating the assembly of the movable elbow at different angles and heights.

[0016] This movable elbow assembly fixture utilizes a first rotary motor located on the vertical side of a disc to control the rotation of a cylinder, changing its angle. A third telescopic rod located on the inner wall of the cylinder drives the cylinder to move, causing four connecting frames located on the outer circumference of the cylinder to move within a sliding groove. These connecting frames move closer to or further away from the connecting frames on the outer circumference of the cylinder. Depending on the size of the movable elbow, the extension and retraction of the third telescopic rod within the connecting frames causes the first and second clamping rings to move as they move closer to or further away from the connecting frames. Based on the radius of the movable elbow, the extension and retraction of the second telescopic rod drives the first clamping ring closer to or further away from the second clamping ring. This design differs from existing devices that cannot effectively fix movable elbows of different sizes and radii. During use, this device facilitates multi-end fixing of movable elbows of different sizes and radii, preventing detachment during assembly and improving efficiency. This swivel elbow assembly fixture facilitates the assembly of swivel elbows at different angles and heights, and allows for multi-end fixing of swivel elbows of different sizes and radii, preventing them from falling off during assembly and improving efficiency.

[0027] Example

[0028] Please see Figures 1 to 4The base frame 1 and the disc 14 mounted on the upper part of the base frame 1 constitute the support structure of the device. A first rotary motor 17 is mounted on the vertical side of the disc 14. A cylinder 8 is sleeved on the drive end of the first rotary motor 17. Four sliding grooves 9 are opened on the outer periphery of the cylinder 8. A third telescopic rod 18 is mounted on the vertical inner wall of the cylinder 8. A cylinder 19 is mounted on the moving part of the third telescopic rod 18. Four connecting frames 10 that fit the inner wall of the sliding grooves 9 are fixed on the periphery of the cylinder 19. Four connecting frames 10 with the same structure are fixed on the vertical inner wall of the sliding grooves 9. A first telescopic rod 12 is mounted on the inner wall of each of the eight connecting frames 10 near the cylinder 8. A second clamping ring 13 for fixing the movable elbow is mounted on the moving part of each of the eight first telescopic rods 12. The first rotary motor 17 on the vertical side controls the cylinder 8 to rotate, changing the angle of the cylinder 8. The third telescopic rod 18 set on the inner wall of the cylinder 8 drives the cylinder 19 to move, causing the four connecting frames 10 set on the outer periphery of the cylinder 19 to move in the slide groove 9, so that the four connecting frames 10 on the outer periphery of the cylinder 19 move closer to or away from the connecting frames 10 on the outer periphery of the cylinder 8. According to the size of the movable elbow, the first clamping ring 11 and the second clamping ring 13 move as the connecting frames 10 move closer to or away from each other by extending and retracting the third telescopic rod 18 set in the connecting frames 10. According to the radius of the movable elbow, the second telescopic rod 15 extends and retracts, driving the first clamping ring 11 to move away from or closer to the second clamping ring 13.

[0029] This device differs from existing devices, which cannot effectively fix movable elbows of different sizes and radii. During use, this device facilitates multi-end fixing of movable elbows of different sizes and radii, preventing them from falling off during assembly and improving efficiency. The other side of each of the eight second clamping rings 13 is attached to a first clamping ring 11. A second telescopic rod 15 is installed on the side of each of the eight first clamping rings 11 away from the cylinder 8, and the moving part of the second telescopic rod 15 is fixed on the side of the second clamping ring 13 near the first clamping ring 11.

[0030] The first clamping ring 11 and the second clamping ring 13 are both connected to the vertical sides of the fixing plate 16. The top of the bottom frame 1 is fixed to the support base 4. The vertical side of the support base 4 is equipped with a linear motor 23. The drive end of the linear motor 23 is equipped with a slider 22. The vertical side of the slider 22 is fixed with a connecting block 21 that fits against the inner wall of the support base 4. The top of the connecting block 21 has a groove. The vertical inner wall of the groove is equipped with a second rotary motor 20. The drive end of the second rotary motor 20 is sleeved with the vertical frame 7 through a rotating rod. The disc 14 is fixed to the vertical side of the vertical frame 7. The vertical side of the support base 4 is fixed with four brackets 6 installed at the top of the bottom frame 1. The bottom of the bottom frame 1 is fixed with two base plates 2. The bottom of the two base plates 2 is equipped with two fixing seats 3.

[0031] The first telescopic rod 12, the second telescopic rod 15, the first rotary motor 17, the third telescopic rod 18, the second rotary motor 20, and the linear motor 23 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. 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.

[0032] Working principle

[0033] In use, the assembly fixture for the movable elbow uses a third telescopic rod 18 located on the inner wall of the cylinder 8 to drive the cylinder 19 to move, causing the connecting frame 10 on the outer periphery of the cylinder 19 to move synchronously in the slide groove 9. This allows the connecting frame 10 on the outer periphery of the cylinder 19 to move closer to or further away from the connecting frame 10 on the inner wall of the slide groove 9. At the same time, the first telescopic rod 12 located on the inner wall of the connecting frame 10 extends and retracts according to the size of the movable elbow. Subsequently, during the driving process of the second telescopic rod 15, the first clamping ring 11 and the second clamping ring 13 move closer to or further away. The first clamping ring 11 and the second clamping ring 13 at different positions are used to fix the two ends of the movable elbow, which facilitates assembly.
