Description

Technical Field

[0001] The utility model relates to the technical field of fixing fixtures, in particular to a fixing fixture for equal-diameter tee processing. Background Art

[0002] A tee is a pipe fitting and a pipe connector, which is used at the branch of the main pipe. An equal-diameter tee is a type of tee, and there are generally two types of tees: equal-diameter tees and reducing tees. Equal-diameter tees are widely used in the construction and maintenance of projects in industries such as petrochemical, oil and natural gas, liquefied gas, chemical fertilizer, power plant, nuclear power, shipbuilding, papermaking, pharmaceutical, food hygiene, and urban construction.

[0003] For example, the authorized announcement number "CN221185595U" is a fixing fixture for equal-diameter tee processing. Although through the cooperation of the fixture cushion block, working cavity, working slide rod, auxiliary slider, auxiliary threaded rod, auxiliary slide opening, working threaded pipe, working threaded rod, limiting rod, connecting block, middle block, and clamping block, the staff only needs to first rotate the auxiliary threaded rod, and the two auxiliary sliders will move towards each other along the direction of the auxiliary threaded rod under the action of the limiting effect, and initially hold the equal-diameter tee to be processed, and then rotate the working threaded pipe to make the two clamping blocks fixedly clamp the equal-diameter tee to be processed, achieving the fixing effect and being able to adapt to equal-diameter tees of different sizes at the same time. However, since the surface of the tee is an arc surface, it is not easy to be tightly held by the clamping block, and the tee is easy to fall off; during processing, since the tee is horizontally clamped and processed from top to bottom, the tee is easy to fall off. Content of the Utility Model

A first motor 3 is provided on the rear surface of the slider 2. A motor rotating shaft 4 is provided on the front surface of the first motor 3. The front end of the motor rotating shaft 4 penetrates through the slider 2 and is provided with a first mounting block 5. A clamping assembly is provided at the front end of the first mounting block 5. The clamping assembly includes a second mounting block 6. A cylinder 7 is provided on the rear surface of the second mounting block 6. A telescopic rod 8 is provided on the front surface of the cylinder 7. The front end of the telescopic rod 8 penetrates through the second mounting block 6 and is hinged with two connecting rods 9. The other ends of the two connecting rods 9 are respectively hinged with a first clamping block 10 and a second clamping block 11. A notch 12 is provided on the front surface of the first clamping block 10. The notch 12 can further fix the end of the middle part of the tee. A first rubber pad 13 is glued to the lower surface of the front part of the first clamping block 10. A second rubber pad 14 is glued to the upper surface of the front part of the second clamping block 11. The first rubber pad 13 and the second rubber pad 14 prevent the hard connection between the tee and the clamping assembly and avoid damaging the tee. First sliding rods 15 are provided on the upper surface of the rear part of the first clamping block 10 and the lower surface of the rear part of the second clamping block 11. The other ends of the two first sliding rods 15 penetrate through the second mounting block 6 and are provided with first end blocks 16. Springs 17 are sleeved on the outer parts of the two first sliding rods 15. One spring 17 is arranged between the upper surface of the first clamping block 10 and the upper inner wall of the second mounting block 6, and the other spring 17 is arranged between the lower surface of the second clamping block 11 and the lower inner wall of the second mounting block 6.

[0018] A third rubber pad 18 is glued to the inner wall of the notch 12. The third rubber pad 18 prevents the direct contact between the notch 12 and the tee and causes damage to the tee.

[0019] A plurality of convex ribs 19 are provided on the opposite side surfaces of the first rubber pad 13 and the second rubber pad 14. The convex ribs 19 play a role in increasing the friction force on the tee.

[0020] The horizontal moving device includes two supporting cross blocks 20. On both sides of the upper surfaces of the two supporting cross blocks 20, supporting vertical blocks 21 are provided. A second sliding rod 22 is provided between two supporting vertical blocks 21 in the same front-back direction. The second sliding rod 22 is slidably connected to the slider 2. A first lead screw 23 is provided between two supporting vertical blocks 21 in the same front-back direction. The first lead screw 23 is threadedly connected to the slider 2. A second motor 24 is provided on the rear surface of the supporting vertical block 21. One end of the first lead screw 23 is rotatably connected to the supporting vertical block 21, and the other end of the first lead screw 23 is connected to the output end of the second motor 24.

[0021] Two support cross blocks 20 are each provided with two second lead screws 25 on their lower surfaces. The lower ends of multiple second lead screws 25 all penetrate through the operation platform 1. Two nuts 26 are threadedly connected to the surfaces of the two second lead screws 25, and the two nuts 26 are respectively arranged above and below the operation platform 1. By moving the second lead screws 25, the up and down positions of the horizontal moving device and the clamping assembly can be adjusted, facilitating the installation of the horizontal moving device and the clamping assembly. The second lead screws 25 can be fixed by the nuts 26 above and below the operation platform 1.

[0022] The upper surface of the second clamping block 11 is provided with a third sliding rod 27. The upper end of the third sliding rod 27 penetrates through the first clamping block 10 and reaches the second end block 28. The third sliding rod 27 makes the relative movement between the first clamping block 10 and the second clamping block 11 smoother.

[0023] Working principle: For the provided clamping assembly, during processing, the opening in the middle of the tee joint is facing upwards, and then the air cylinder 7 is started, causing the telescopic rod 8 to shorten backward. Since the telescopic rod 8 is hinged to the two connecting rods 9, and the two connecting rods 9 are hinged to the first clamping block 10 and the second clamping block 11, the first clamping block 10 and the second clamping block 11 move in a direction away from each other. Then, the tee joint is placed between the first clamping block 10 and the second clamping block 11, and the upward part of the tee joint is placed into the notch 12. Then, the air cylinder 7 is started in the reverse direction, causing the telescopic rod 8 to extend, making the first clamping block 10 and the second clamping block 11 move in a direction towards each other. Under the action of the compression force of the spring 17, the first clamping block 10 and the second clamping block 11 can more easily and quickly clamp the tee joint; at this time, the tee joint can be processed. When the tee joint needs to be rotated, the first motor 3 is started, causing the motor rotating shaft 4 to rotate, thereby driving the clamping assembly to rotate. The tee joint can be easily clamped by the clamping assembly and is not likely to fall off. During processing, since the tee joint is clamped vertically and processed from top to bottom, the tee joint is not likely to fall off. When the clamping assembly needs to be moved back and forth, the second motor 24 is started, causing the first lead screw 23 to rotate. Since the first lead screw 23 is threadedly connected to the slider 2 and the second sliding rod 22 is slidably connected to the slider 2, the slider 2 can be moved back and forth to ensure that the clamping assembly moves to the specified position.

[0024] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
