Description

Technical Field

[0001] This utility model relates to the field of round tube cutting technology, specifically to a combined auxiliary support structure for a round tube cutting machine. Background Technology

[0002] Round tubes refer to steel materials with open ends and a hollow concentric circular cross-section, which are relatively long and can be used for pipelines, thermal equipment, machinery industry, oil and geological drilling, containers, chemical industry and special purposes. In the production and processing of round tubes, they need to be cut into different lengths to meet different needs. Currently, a cutting machine is usually used to cut round tubes. When cutting, the round tube is placed on a workbench, which is usually flat. The workbench needs to be fixed with a clamp to ensure that the round tube does not shake during cutting.

[0003] In the existing technology, although general round pipe cutting machines can provide clamping support for round pipes of fixed diameter, the clamping effect is poor for round pipes of different diameters and the operation is cumbersome. Therefore, it is necessary to design a combined auxiliary support structure for round pipe cutting machines to solve the problems existing in the current technology. Utility Model Content

[0004] To address the problems in the background art, this utility model proposes a combined auxiliary support structure for a round pipe cutting machine. This utility model can provide stable clamping for round pipes of different diameters while being easy to operate.

[0005] To solve the above problems, this utility model adopts the following technical solution: a combined auxiliary support structure for a round tube cutting machine, including a base, a top seat, and multiple support rods connected between the base and the top seat. A V-shaped groove is provided through the front and back of the top surface of the base. Two bent plates are symmetrically arranged on the left and right sides of the V-shaped groove. The horizontal plate portion of the two bent plates is detachably connected to the top surface of the base by bolts. The inclined plate portion of the two bent plates is parallel to the side of the corresponding V-shaped groove. The two inclined plate portions can move away from or close to each other and are used to provide support for the bottom of the round tube. Two threaded rods are provided through the top surface of the top seat. The two threaded rods are threadedly connected to the top seat. The lower ends of the two threaded rods abut against the left and right sides of the top of the round tube, respectively.

[0006] Furthermore, the lower ends of the two threaded rods are rotatably connected to mounting blocks, and columnar pressure blocks are fixedly installed on the bottom surface of the mounting blocks. The length direction of the columnar pressure blocks is consistent with the length direction of the circular tube, and the side of the columnar pressure blocks is used to abut against the side of the circular tube. An elastic bellows is sleeved on the threaded rods, and the upper end of the elastic bellows is sealed to the bottom surface of the top seat, and the lower end is sealed to the top surface of the mounting blocks.

[0007] Furthermore, the cylindrical sides of both of the columnar pressure blocks are covered with a rubber layer, which is used to abut against the side of the cylindrical tube.

[0008] Furthermore, two symmetrical sliding grooves are formed on the top seat, and both sliding grooves extend along the left and right direction of the top seat. Two sliders are slidably installed in the two sliding grooves in a corresponding manner. The top surface of each slider has a through threaded hole, and two threaded rods are threadedly connected to the threaded holes on the two sliders in a corresponding manner. Adjusting screws are threaded through the left and right sides of the top seat. The outer end of the adjusting screw is located on the outer side of the top seat, and the inner end is rotatably connected to the side of the corresponding slider.

[0009] Furthermore, each of the two horizontal plates has a strip-shaped hole on its top surface, and the base has a threaded blind hole on its top surface corresponding to the bottom of each of the two strip-shaped holes. The bolts passing through the two strip-shaped holes are threadedly connected to the threaded blind holes.

[0010] Furthermore, each of the two inclined plates includes a plurality of spaced-apart support teeth, the upper ends of which are connected to the side of the corresponding horizontal plate, and the lower ends of which extend downward into the V-shaped groove. The plurality of support teeth of the two inclined plates are staggered and interlocked.

[0011] Furthermore, the plurality of the support rods are detachably connected to the base and the top seat by bolts.

[0012] Furthermore, a rotating handle is connected to the upper end of both threaded rods.

[0013] The beneficial effects of this invention are as follows: This invention supports the bottom of a circular tube using the inclined plates of two movable bending plates. When the two inclined plates are far apart, they provide support for large-diameter circular tubes; when they are close together, the support effect is better for small-diameter circular tubes. Rotating the two threaded rods downwards causes their lower ends to abut against the upper left and right sides of the circular tube, thus clamping and fixing the tube. Compared to traditional circular tube clamping and support devices, this invention provides stable clamping for circular tubes of different diameters while being easy to operate.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This invention uses the inclined plate portions 7 of two movable bending plates 5 to support the bottom of the circular tube 8. When the two inclined plate portions 7 are far apart, they can provide support for large-diameter circular tubes 8. When the two inclined plate portions 7 are close together, the support effect is better for small-diameter circular tubes 8. Rotating the two threaded rods 9 causes them to move downwards, and the lower ends of the two threaded rods 9 abut against the left and right sides of the upper part of the circular tube 8 to clamp and fix the circular tube 8. Compared with traditional circular tube 8 clamping and support devices, this invention can provide stable clamping for circular tubes 8 of different diameters while being easy to operate.

[0020] Specifically, such as Figure 1 and Figure 2 As shown, a combined auxiliary support structure for a round tube 8 cutting machine includes a base 1, a top seat 2, and multiple support rods 3 connected between the base 1 and the top seat 2. A V-shaped groove 4 is provided through the front and back of the top surface of the base 1. Two bent plates 5 are symmetrically arranged on the left and right sides of the V-shaped groove 4. The horizontal plate portion 6 of the two bent plates 5 is detachably connected to the top surface of the base 1 by bolts. The inclined plate portion 7 of the two bent plates 5 is parallel to the side of the corresponding V-shaped groove 4. The two inclined plate portions 7 can move away from or close to each other and are used to provide support for the bottom of the round tube 8. Two threaded rods 9 are provided through the top surface of the top seat 2. The two threaded rods 9 are threadedly connected to the top seat 2. The lower ends of the two threaded rods 9 abut against the left and right sides of the top of the round tube 8, respectively.

[0021] Furthermore, the lower ends of the two threaded rods 9 are rotatably connected to mounting blocks 10. A columnar pressure block 11 is fixedly installed on the bottom surface of the mounting block 10. The length direction of the columnar pressure block 11 is consistent with the length direction of the round tube 8. The side of the columnar pressure block 11 is used to abut against the side of the round tube 8. An elastic bellows 12 is sleeved on the threaded rod 9. The upper end of the elastic bellows 12 is sealed to the bottom surface of the top seat 2, and the lower end is sealed to the top surface of the mounting block 10.

[0022] Furthermore, both cylindrical pressure blocks 11 are covered with a rubber layer 13 on their cylindrical sides, which is used to abut against the side of the circular tube 8. The rubber layer 13 is provided on the side of the cylindrical pressure block 11 to prevent the cylindrical pressure block from directly acting on the side of the circular tube 8 and causing indentations when the threaded rod 9 is rotated.

[0023] Furthermore, two symmetrical sliding grooves 14 are provided on the top seat 2. Both sliding grooves 14 extend along the left and right direction of the top seat 2. Two sliders 15 are slidably installed in the two sliding grooves 14, and threaded holes are provided on the top surfaces of the two sliders 15. Two threaded rods 9 are threadedly connected to the threaded holes on the two sliders 15, respectively. Adjusting screws 16 are threaded through the left and right sides of the top seat 2. The outer end of the adjusting screw 16 is located on the outer side of the top seat 2, and the inner end is rotatably connected to the side of the corresponding slider 15.

[0024] Furthermore, each of the two horizontal plate portions 6 has a strip-shaped hole 17 on its top surface, and the top surface of the base 1 has a threaded blind hole corresponding to the bottom of each of the two strip-shaped holes 17. The bolts passing through the two strip-shaped holes 17 are threadedly connected to the threaded blind holes.

[0025] Furthermore, each of the two inclined plate portions 7 includes a plurality of spaced-apart support teeth 18. The upper ends of the plurality of support teeth 18 are connected to the side of the corresponding horizontal plate portion 6, and the lower ends of the plurality of support teeth 18 extend downward into the V-shaped groove 4. The plurality of support teeth 18 of the two inclined plate portions 7 are staggered and interlocked. Because the plurality of support teeth 18 of the two inclined plate portions 7 are staggered and interlocked, mutual interference can be avoided when the two inclined plate portions 7 come together.

[0026] Furthermore, the plurality of support rods 3 are detachably connected to the base 1 and the top seat 2 by bolts. The detachable connection of the base 1, the top seat 2, and the plurality of support rods 3 facilitates their maintenance and replacement.

[0027] Furthermore, a rotating handle 19 is connected to the upper end of each of the two threaded rods 9. The rotating handle 19 makes it easier to rotate the threaded rods 9.

[0028] In use, this invention supports the bottom of the circular tube 8 through the inclined plate portions 7 of two movable bending plates 5. When the two inclined plate portions 7 are far apart, they can provide support for large-diameter circular tubes 8; when the two inclined plate portions 7 are close together, the support effect is better for small-diameter circular tubes 8. Rotating the two threaded rods 9 causes them to move downwards, and the lower ends of the two threaded rods 9 abut against the left and right sides of the upper part of the circular tube 8 to clamp and fix the circular tube 8. Compared with traditional circular tube 8 clamping and support devices, this invention can provide stable clamping for circular tubes 8 of different diameters while being easy to operate.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
