Description

Technical Field

[0001] The present invention relates to the technical field of cutting, and specifically to a cutting device for steel structure assembly. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates. Steel structure assembly refers to the process of assembling steel structure components into an integral structure by means of welding, bolt connection or riveting, etc. This process is widely used in the construction field, especially in structures such as large factories, stadiums, super high-rise buildings and bridges. The construction speed is fast: since most of the work is completed in the factory and only assembly is required on site, the construction period is greatly shortened. The quality is controllable: the quality control of factory production is more stringent, reducing the errors in on-site construction. The material utilization rate is high: standardized production reduces material waste, and the components can be reused. During the steel structure assembly process, cutting equipment is required to cut the steel structures at the construction site to facilitate accurate splicing.

[0003] When the size of the steel structure material at the construction site is larger than the size required for splicing, cutting is required to ensure that the steel structure can be spliced. In order to improve the cutting accuracy of the steel structure, marks need to be made on the steel structure material for cutting.

[0016] The present invention has the following beneficial effects:

[0017] 1. In the cutting device for steel structure assembly, the provided placing groove facilitates the placement of the steel structure workpiece to be cut on the cutting table for marking. The cutting position of the steel structure workpiece can be marked by a number of first marking pens on the marking box, so as to improve the cutting accuracy of the steel structure workpiece and reduce the cutting error. The L-shaped abutting rod is slidably connected to the strip-shaped abutting rod, which is convenient for adjusting according to the cutting length of the steel structure workpiece, so as to meet the cutting lengths of different steel structure workpieces. When the steel structure workpiece moves on the placing groove, it can abut against the L-shaped abutting rod, prompting the strip-shaped abutting rod to drive the abutting block to deflect and abut against the abutting ring, so as to achieve the purpose of automatically marking the surface of the steel structure workpiece by the hollow rod driving a number of first marking pens on the marking box. When encountering a large number of steel structure workpieces with the same cutting size, the steel structure workpieces can be directly placed in the placing groove for automatic marking treatment, without the need to measure and mark the cutting length of each steel structure workpiece manually, greatly reducing the time required for measuring and marking the steel structure workpiece and improving the cutting efficiency of the cutting machine for the steel structure workpiece.

[0018] The length can be locked after adjustment between the L-shaped contact rod and the strip-shaped contact rod through a locking screw, avoiding position deviation when the steel structure workpiece contacts the L-shaped contact rod, which affects the accuracy of the marking position. The deflection angle of the L-shaped contact rod can be restricted by the limit block arranged on the cutting table. When the position of the L-shaped contact rod changes, the limit block can ensure that the deflection angles of the L-shaped contact rods at different positions are consistent, avoiding position deviation when the first marking pen marks the steel structure workpiece and affecting the accuracy of the workpiece marking position.

[0019] 2. In the cutting device for steel structure assembly, when a number of first teeth fixed on the hollow rod mesh with a number of first tooth grooves formed on the circular rotating block, the circular rotating block can drive the hollow rod to rotate synchronously when it rotates, so that the hollow rod can drive the marking box and a number of first marking pens to rotate synchronously, prompting the rotating first marking pens to make marking lines at different angles on the steel structure workpiece, meeting the requirements for marking at different cutting angles of steel structure workpieces, improving the scope of application. The set limit component can restrict the position of the circular rotating block, preventing it from deflecting after adjusting the rotation angle of the hollow rod, and improving the stability of the working position after the angle of the first marking pen deflects.

[0020] 3. In the cutting device for steel structure assembly, the second marking pen slidably connected to the marking box can make marks of different thicknesses. In order to identify the workpiece and better determine information such as the usage position of the steel during subsequent assembly, the positioning time can be shortened during cutting. By rotating the adjusting rod on the hollow rod manually, one end of the adjusting rod can drive two contact strips to rotate inside the marking box, achieving the purpose of the two contact strips contacting the contact wedge on the second marking pen, enabling the second marking pen to extend from the marking box when in use and perform marking on the surface of the steel structure workpiece to be marked;

[0021] Through the cooperation of the mounting post and the third torsion spring, the contact block can be rotatably connected to the strip-shaped contact rod. When the strip-shaped contact rod deflects, the contact block can contact the contact ring. After the cutting position of the steel structure workpiece is marked, manually pull the hollow rod to move on the cutting table, prompting the contact ring to contact the contact block, causing the contact block to deflect, facilitating the first marking pen or the second marking pen to move away from the surface of the steel structure workpiece. When the marked steel structure workpiece is removed from the placement groove, it can avoid contact with the first marking pen or the second marking pen and cause mismarking.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Example 1, please refer to Figures 1 to 8, A cutting device for steel structure assembly, including a cutting table 1, a rotatable cutting machine 2 is arranged on the cutting table 1, a placing groove 3 is arranged on one side of the cutting table 1, a marking box 4 is arranged on one side of the placing groove 3, a number of first marking pens 5 are fixed on the marking box 4, a hollow rod 6 is fixed on one side of the marking box 4, one end of the hollow rod 6 is elastically connected with the cutting table 1 through a first spring 7, and a resisting ring 8 is fixed on the hollow rod 6;

[0033] An L-shaped resisting rod 9 is arranged in the placing groove 3, a strip-shaped resisting rod 10 is slidably connected to the L-shaped resisting rod 9, a locking screw 12 is threadedly connected to the L-shaped resisting rod 9, the strip-shaped resisting rod 10 is rotatably connected to the cutting table 1, and a limiting block 11 is connected to the L-shaped resisting rod 9, and the limiting block 11 is elastically connected with the L-shaped resisting rod 9 through a second spring 18.

[0034] Scale lines 13 are arranged in the placing groove 3, a first strip-shaped groove 14 is opened on one side of the cutting table 1, a threaded section 15 is fixed on the limiting block 11, the threaded section 15 is located in the first strip-shaped groove 14, and a knob 16 is threadedly connected to the threaded section 15, and a rotating bracket 17 is fixed on the cutting table 1, and the rotating bracket 17 is rotatably connected to the strip-shaped resisting rod 10.

[0035] A partition plate 22 is arranged on one side of the placing groove 3, the partition plate 22 is fixed on the cutting table 1, and a second strip-shaped groove 23 is opened on the partition plate 22, and one end of the L-shaped resisting rod 9 is slidably connected in the second strip-shaped groove 23.

[0036] A U-shaped seat 31 is fixed on the cutting table 1, a rotating shaft 32 is rotatably connected to the U-shaped seat 31, a second torsion spring 33 is connected between the rotating shaft 32 and the U-shaped seat 31, and a machine frame 34 is fixed on the rotating shaft 32, and the cutting machine 2 is fixed on the machine frame 34.

[0037] An installation column 35 is fixed on the strip-shaped resisting rod 10, a resisting block 36 is rotatably connected to the installation column 35, the resisting block 36 abuts against the surface of the resisting ring 8, and a third torsion spring 37 is connected between the resisting block 36 and the installation column 35.

[0038] Reference Figures 1 - 7, when marking a steel structure workpiece, first measure the length of the steel structure workpiece to be cut. After determining the cutting length, refer to the scale line 13 and adjust the relative moving distance between the L-shaped abutting rod 9 and the strip-shaped abutting rod 10. The L-shaped abutting rod 9 moves horizontally in the second strip-shaped groove 23 opened on the partition plate 22 so that the position of the adjusted L-shaped abutting rod 9 corresponds to the cutting length of the steel structure workpiece. Lock the L-shaped abutting rod 9 and the strip-shaped abutting rod 10 with the locking screw 12. Move the steel structure workpiece in the placement groove 3. One end of the steel structure workpiece to be cut abuts against the L-shaped abutting rod 9. The L-shaped abutting rod 9 drives the strip-shaped abutting rod 10 to rotate on the rotating bracket 17, and the second spring 18 stores energy. When the L-shaped abutting rod 9 abuts against the limit block 11, it stops deflecting. The deflected strip-shaped abutting rod 10 drives the abutting block 36 to abut against the abutting ring 8, prompting the hollow rod 6 to slide on the cutting table 1. The first spring 7 stores energy, prompting the hollow rod 6 to drive the marking box 4 close to the surface of the steel structure workpiece, facilitating the automatic marking process of the cutting positions of the steel structure workpiece by several first marking pens 5. After the marking of the cutting positions of the steel structure workpiece is completed, manually pull the hollow rod 6 horizontally. At the same time, the abutting ring 8 abuts against the abutting block 36, prompting the abutting block 36 to deflect on the mounting column 35, and the third torsion spring 37 stores energy, separating several first marking pens 5 on the marking box 4 from the surface of the steel structure workpiece. When the marked steel structure workpiece is removed from the placement groove 3, it is convenient to avoid contact with the first marking pen 5 or the second marking pen 24 to cause mismarking;

[0039] The marked steel structure workpiece is placed on the cutting table 1. Refer to Figure 1 and Figure 2 , the motor set in the cutting machine 2 drives the saw blade to rotate at high speed. When the saw blade aligns with the marked position, manually press the machine frame 34, causing the rotating shaft 32 to rotate on the U-shaped seat 31. The second torsion spring 33 stores energy, and the machine frame 34 rotates, achieving the purpose of cutting the marked position of the steel structure workpiece by the saw blade.

[0040] When encountering a large number of steel structure workpieces with the same cutting size, the steel structure workpieces can be directly placed in the placement groove 3 for automatic marking processing, without the need to measure and mark the cutting length of each steel structure workpiece manually, greatly reducing the time required for measuring and marking the steel structure workpieces and improving the cutting efficiency of the cutting machine 2 for the steel structure workpieces.

[0041] Refer to Figures 5 - 7, when the position of the L-shaped contact rod 9 is adjusted, under the action of the second spring 18, the L-shaped contact rod 9 can drive the threaded section 15 fixed on the limit block 11 to move synchronously in the first strip-shaped groove 14. When the position of the L-shaped contact rod 9 changes, the limit block 11 can ensure that the deflection angles of the L-shaped contact rods 9 at different positions are consistent, avoiding position deviation when the first marking pen 5 marks the steel structure workpiece and affecting the accuracy of the workpiece marking position. Since the knob 16 is threadedly connected to the threaded section 15, it is convenient to disassemble the limit block 11 on the cutting table 1 while ensuring the smooth performance of the horizontal movement of the limit block 11.

[0042] Reference Figure 8 , in order to prevent waste chips from splashing to one side of the cutting table 1 during the workpiece cutting process and affecting the adjustment of the L-shaped contact rod 9, a cover plate 38 is hinged on the partition plate 23. The cover plate 38 can prevent waste chips from falling onto the cutting table 1. Since the sizes of the workpieces placed in the placement groove 3 are different, setting the cover plate 38 will affect the marking of the workpieces.

[0043] Reference Figure 8 , a limit plate 39 is fixed on the cutting table 1. A clamping plate 40 is arranged on one side of the limit plate 39. A threaded rod 41 is threadedly connected to the cutting table 1. One end of the threaded rod 41 is rotatably connected to the clamping plate 40. The clamping distance between the clamping plate 40 and the limit plate 39 can be adjusted by the threaded rod 41, facilitating the clamping of the cut workpiece and improving the cutting effect of the workpiece.

[0044] Embodiment 2. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1 to 8 , a circular rotating block 20 and a limit component for limiting the circular rotating block 20 are provided on one side of the cutting table 1. A plurality of first teeth 19 are fixed on the end of the hollow rod 6. A plurality of first tooth grooves 21 are provided on the circular rotating block 20 at equal circumferential intervals. The circular rotating block 20 is slidably connected to the hollow rod 6, and the first teeth 19 are meshed with the first tooth grooves 21.

[0045] The limit component includes a third spring 201. The two ends of the third spring 201 are respectively fixed to the cutting table 1 and the end face of the circular rotating block 20. An arc-shaped tooth block 203 is fixed to one end of the circular rotating block 20. An annular tooth block 202 is fixed to the cutting table 1. The arc-shaped tooth block 203 is meshed with the annular tooth block 202.

[0046] Since the splicing angles of some steel structure workpieces are different, when cutting, it is necessary to cut off the excess dimensions according to the splicing angles, so that several first marking pens 5 need to be adjusted according to the cutting angles during the marking process. Reference Figures 2 - 6, by manually rotating the circular rotating block 20, under the cooperation of the first tooth groove 21 and the first tooth 19, the circular rotating block 20 drives the hollow rod 6 to rotate synchronously, so that the hollow rod 6 can drive the marking box 4 and several first marking pens 5 to rotate synchronously, prompting the rotating several first marking pens 5 to make marking lines at different angles on the steel structure workpiece, meeting the marking requirements for different cutting angles of the steel structure workpiece, and improving the scope of application;

[0047] In order to prevent the hollow rod 6 from deflecting after the angle is adjusted and affecting the marking accuracy, it is necessary to limit the rotation angle of the hollow rod 6. Refer to Figure 4 , the arc-shaped tooth block 203 fixed on the circular rotating block 20 can rotate synchronously with the circular rotating block 20. When the angle of the hollow rod 6 is adjusted, under the elastic force of the third spring 201, the circular rotating block 20 drives the arc-shaped tooth block 203 to approach the annular tooth block 202 fixed on the cutting table 1, so as to achieve the purpose of meshing the arc-shaped tooth block 203 with the annular tooth block 202, thereby restricting the rotation of the arc-shaped tooth block 203 and the circular rotating block 20.

[0048] Embodiment Three, this embodiment is an improvement based on Embodiment Two. Specifically, please refer to Figures 1 to 8 , there is another technical solution for the limiting component. The limiting component includes several second tooth grooves 204, and the several second tooth grooves 204 are equidistantly distributed on the circumferential surface of the circular rotating block 20, and the circular rotating block 20 is rotatably connected to the cutting table 1. A guide block 205 is fixed on the cutting table 1, a sliding rod 206 is slidably connected to the guide block 205, a fourth spring 208 is connected between the sliding rod 206 and the guide block 205, and a clamping block 207 is fixed to the lower end of the sliding rod 206.

[0049] Refer to Figure 3 , when the circular rotating block 20 rotates on the cutting table 1, it can drive the hollow rod 6 to rotate synchronously, so as to achieve the purpose of adjusting the marking angle. When the angle of the hollow rod 6 is adjusted, under the elastic force of the fourth spring 208, it can achieve the purpose of driving the sliding rod 206 to slide vertically on the guide block 205, prompting the sliding rod 206 to drive the clamping block 207 to be stuck in the second tooth groove 204 on the circumferential surface of the circular rotating block 20, thereby achieving the purpose of restricting the rotation angle of the circular rotating block 20, and improving the marking accuracy of the hollow rod 6 after the angle is adjusted.

[0050] Embodiment Four, this embodiment is an improvement based on Embodiment One. Specifically, please refer to Figures 1 to 8 , two second marking pens 24 are slidably connected to the marking box 4, a fifth spring 25 is connected between the second marking pen 24 and the marking box 4, a contact wedge block 26 is fixed to one end of the second marking pen 24, and a limiting convex block 30 is provided on the contact wedge block 26.

[0051] A regulating rod 27 is rotatably connected inside a hollow rod 6. A first torsion spring 28 is connected between the regulating rod 27 and the hollow rod 6. One end of the regulating rod 27 is fixed with two abutting strips 29, and the abutting strips 29 are abutted against abutting wedges 26.

[0052] In order to identify the workpiece and better determine information such as the usage position of the steel during subsequent assembly, and shorten the cutting and positioning time, refer to Figure 4 , it is necessary to manually rotate the regulating rod 27 to make the regulating rod 27 rotate inside the hollow rod 6. The first torsion spring 28 stores energy. The regulating rod 27 drives the two abutting strips 29 to rotate, so as to achieve the purpose of the abutting strips 29 abutting against the abutting wedges 26, prompting the two thicker second marking pens 24 to protrude from the marking box 4 and contact the surface of the steel structure workpiece for marking. The fifth spring 25 stores energy. The abutting distance of the abutting strips 29 on the abutting wedges 26 can be limited by the limiting convex blocks 30, avoiding the regulating rod 27 rotating too much and the abutting strips 29 releasing the abutment against the abutting wedges 26, thus affecting the protruding length of the second marking pen 24.

[0053] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0054] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
