Description

Technical Field

[0001] This invention relates to the field of steel processing technology, specifically to a steel continuous groove edge grinding mechanism. Background Technology

[0002] Steel is a material with specific shapes, dimensions, and properties, made from steel ingots, billets, or other steel products through pressure processing. Steel is an important category of metal plastic processing products. Of the total steel production, except for a small portion formed by casting and powder metallurgy, the vast majority is plastically processed into steel products. In addition to having a specified chemical composition, good surface quality, and precise geometric dimensions, steel products possess sufficient tensile strength, yield strength, hardness, toughness, and other mechanical properties. Some also exhibit weldability, ease of forming, and certain special physicochemical properties (such as corrosion resistance, high-temperature resistance, and magnetic induction properties). Based on their cross-sectional shape, steel products can be divided into four main categories: profiles, plates, pipes, and metal products.

[0003] After the steel base is made, multiple grooves need to be machined on it to facilitate the machining of threaded holes. However, since the grooves on the base are spaced apart, after the base is formed, the edges of the grooves can only be ground manually using a hand-held grinding machine, which is labor-intensive and inefficient. Summary of the Invention

[0004] The purpose of this invention is to solve the above problems and provide a steel continuous groove edge grinding mechanism that can realize automatic grinding of the groove position of steel and reduce labor intensity.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A steel continuous groove edge grinding mechanism includes a base, a swing arm disposed on the base and swinging on the base, a rotating frame disposed at the end of the swing arm and rotatably connected to the swing arm at its upper end, a first rotating shaft disposed at the end of the swing arm, a second rotating shaft disposed on the rotating frame, and a grinding disc disposed at the lower end of the second rotating shaft. The front end of the first rotating shaft and the upper end of the second rotating shaft are provided with mutually meshing bevel gears. The swing arm is provided with a driving mechanism for driving the first rotating shaft to rotate.

[0007] The driving mechanism includes a driving shaft mounted on the swing arm and rotating on the swing arm. The driving shaft is connected to the first rotating shaft via a first belt. When the driving shaft rotates, the rotating frame reciprocates under the action of the first linkage mechanism. When the driving shaft rotates, the swing arm swings up and down under the action of the second linkage mechanism.

[0008] The first linkage mechanism includes a movable block disposed on the swing arm and moving on the swing arm, and a drive disk disposed on the drive shaft. The movable block has a first elongated hole at its left end, and the drive disk has a first drive rod at an eccentric position that cooperates with the first elongated hole. The upper end of the rotating frame has a swing arm with a second elongated hole, and the right end of the movable block has a second drive rod that cooperates with the second elongated hole.

[0009] The second linkage mechanism includes a cam mounted on the drive shaft and a support frame mounted on the base that cooperates with the cam.

[0010] Furthermore, the left end of the swing arm is rotatably connected to the base, and the right end of the base is provided with a vertical plate for supporting the swing arm.

[0011] Furthermore, a tension spring is provided between the swing arm and the base.

[0012] Furthermore, the axis of the first rotating shaft overlaps with the axis of the rotating frame shaft, and the axis of the second rotating shaft is in the vertical direction.

[0013] Furthermore, the rotating frame is L-shaped when viewed from the side.

[0014] Furthermore, the swing arm is equipped with a motor, and the output shaft of the motor is connected to the drive shaft via a second belt.

[0015] Furthermore, the swing arm is provided with a guide rod that passes through the moving block and is slidably connected to the moving block.

[0016] The beneficial effects of this invention are:

[0017] 1. This invention includes a base, a swing arm mounted on the base and swinging on the base, a rotating frame mounted at the end of the swing arm and rotatably connected to the swing arm at its upper end, a first rotating shaft mounted at the end of the swing arm, a second rotating shaft mounted on the rotating frame, and a grinding disc mounted at the lower end of the second rotating shaft. Both the front end of the first rotating shaft and the upper end of the second rotating shaft are provided with meshing bevel gears. The swing arm is equipped with a drive mechanism to drive the first rotating shaft to rotate. When grinding the edge of a continuous groove in steel, the steel is continuously fed, and the drive mechanism drives the first rotating shaft to rotate continuously. Under the action of the bevel gears, the second rotating shaft rotates synchronously, thereby driving the grinding disc to rotate. When the groove position corresponds to the grinding disc position, the rotating frame drives the second rotating shaft to swing outward, and at this time, the swing arm swings downward. The grinding disc grinds the edge of the groove. After grinding is completed, the rotating frame drives the second rotating shaft to swing downward, and at this time, the swing arm swings upward. The grinding disc does not interfere with the sidewall of the groove. This achieves grinding of continuous grooves and reduces labor intensity.

[0018] 2. The driving mechanism in this invention includes a drive shaft mounted on and rotating on the swing arm. The drive shaft is connected to the first rotating shaft via a first belt. When the drive shaft rotates, the rotating frame reciprocates under the action of a first linkage mechanism, and the swing arm swings up and down under the action of a second linkage mechanism. When the drive shaft rotates, the first rotating shaft rotates under the action of the first belt, and the first rotating shaft drives the grinding disc to rotate via a bevel gear and a second rotating shaft. Simultaneously, the rotating frame reciprocates under the action of the first linkage mechanism, and the swing arm swings downward under the action of the second linkage mechanism, allowing the grinding disc to sequentially penetrate into the groove position. After grinding is completed, the swing arm swings upward under the action of the second linkage mechanism, facilitating the removal of the grinding disc from the groove position without interfering with the sidewall of the groove.

[0025] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0026] like Figure 1 As shown, a continuous groove edge grinding mechanism for steel includes a base 1, a swing arm 2 mounted on the base 1 and swinging on the base 1, a rotating frame 3 mounted at the end of the swing arm 2 and rotatably connected to the upper end of the swing arm 2, a first rotating shaft mounted at the end of the swing arm 2, a second rotating shaft 4 mounted on the rotating frame 3, and a grinding disc 6 mounted at the lower end of the second rotating shaft 4. The front end of the first rotating shaft and the upper end of the second rotating shaft 4 are both provided with meshing bevel gears 5. The swing arm 2 is provided with a driving mechanism to drive the first rotating shaft to rotate. When grinding the continuous groove edges of the steel, the steel is continuously fed, and the drive mechanism drives the first rotating shaft to rotate continuously. Under the action of the bevel gear, the second rotating shaft 4 rotates synchronously, thereby driving the grinding disc to rotate. When the groove position corresponds to the position of the grinding disc 6, the rotating frame 3 drives the second rotating shaft 4 to swing outward, and at the same time, the swing rod 2 swings downward. The grinding disc 6 grinds the edge of the groove. After grinding is completed, the rotating frame 3 drives the second rotating shaft 4 to swing downward, and at the same time, the swing rod 2 swings upward. The grinding disc 6 will not interfere with the side wall of the groove. This achieves grinding of continuous grooves and reduces labor intensity.

[0027] like Figure 1 and Figure 4 As shown, the driving mechanism includes a drive shaft 7 mounted on and rotating on the swing arm 2. The drive shaft 7 is connected to the first rotating shaft via a first belt 8. When the drive shaft 7 rotates, the rotating frame 3 reciprocates under the action of a first linkage mechanism, and the swing arm 2 swings up and down under the action of a second linkage mechanism. When the drive shaft 7 rotates, the first rotating shaft rotates under the action of the first belt, and the first rotating shaft drives the grinding disc 6 to rotate via a bevel gear and a second rotating shaft. At the same time, the rotating frame 3 reciprocates under the action of the first linkage mechanism, and the swing arm 2 swings downward under the action of the second linkage mechanism. The grinding disc 6 sequentially penetrates into the groove position. After grinding is completed, the swing arm 2 swings upward under the action of the second linkage mechanism, which facilitates the grinding disc 6 leaving the groove position and prevents interference with the side wall of the groove.

[0028] like Figure 1 and Figure 2As shown, the first linkage mechanism includes a movable block 9 mounted on and moving on the swing arm 2, and a drive disk 10 mounted on the drive shaft 7. The movable block 9 has a vertically oriented first elongated hole 11 at its left end. The drive disk 10 has a first drive rod 12 eccentrically positioned to engage with the first elongated hole 11. The upper end of the rotating frame 3 has a swing arm 13 with a second elongated hole 14. The right end of the movable block 9 has a second drive rod 15 engaging with the second elongated hole 14. When the drive shaft 7 rotates, the drive disk 10 rotates accordingly. Under the action of the first drive rod 12 and the first elongated hole 11, the movable block 9 moves left and right. At this time, under the action of the second drive rod 15 and the second elongated hole 14, the rotating frame 3 reciprocates. This mechanical structure achieves linkage between the rotation of the second rotating shaft and the movement of the movable block, eliminating the need for a separate drive mechanism, resulting in low cost and high reliability.

[0029] like Figure 4 As shown, the second linkage mechanism includes a cam 16 mounted on the drive shaft 7 and a support frame 17 mounted on the base 1 that cooperates with the cam 16. When the drive shaft 7 rotates, the cam 16 and the support frame 17 cooperate, thereby realizing the up-and-down swing of the rocker arm 2.

[0030] like Figure 1 As shown, the left end of the swing rod 2 is rotatably connected to the base 1, and the right end of the base 1 is provided with a vertical plate 18 for supporting the swing rod 2.

[0031] like Figure 3 As shown, a tension spring 19 is provided between the rocker arm 2 and the base 1. Under the action of the tension spring 19, the cam 16 is always engaged with the support frame 17.

[0032] The axis of the first rotating shaft overlaps with the axis of the rotating frame 3, and the axis of the second rotating shaft 4 is in the vertical direction.

[0033] The rotating frame 3 is L-shaped when viewed from the side, and the vertical part of the L-shaped rotating frame 3 is rotatably connected to the swing rod 2.

[0034] like Figure 4 As shown, the swing arm 2 is equipped with a motor 20, and the output shaft of the motor 20 is connected to the drive shaft 7 via a second belt 21.

[0035] like Figure 4 As shown, the swing arm 2 is provided with a guide rod 22 that passes through the moving block 9 and is slidably connected to the moving block 9.
