Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel extrusion part manufacturing, and particularly relates to a fastening device for stainless steel extrusion parts. Background Technique

[0002] Stainless steel is short for stainless acid-resistant steel. Steel types that are resistant to weak corrosive media such as air, steam, and water or have stainless properties are called stainless steel; while steel types that are resistant to chemical corrosive media (chemical etching such as acids, alkalis, and salts) are called acid-resistant steel. Because it is not easy to corrode, stainless steel is often made into various extrusion parts. After extrusion, due to the unevenness of extrusion, the extrusion parts need to be fixed and then subsequent processing is carried out.

[0003] Currently, when fixing extrusion parts, usually a long pressing plate needs to fix two stainless steel extrusion parts. Due to the long pressing plate and the tolerance in the thickness direction of the stainless steel extrusion parts, after the stainless steel extrusion parts are clamped, sometimes the first stainless steel extrusion part is fixed tightly, while the second stainless steel extrusion part is not fixed tightly; sometimes the first stainless steel extrusion part is not fixed tightly, while the second stainless steel extrusion part is fixed tightly, resulting in unstable dimensions of the processed stainless steel extrusion parts; separating into two small pressing plates to fix the stainless steel extrusion parts, the stainless steel extrusion parts are all fixed tightly, but the clamping time is increased, making the processing efficiency slower.

[0018] 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.

[0019] The present invention provides a fastening device for stainless steel extrusions as Figures 1-5 shown, which includes an operating table 1. A bearing plate 2 is fixedly connected to the top surface of the operating table 1. A flexible pressing plate is provided on the top surface of the bearing plate 2. The flexible pressing plate includes a first pressing plate 3. One end of the first pressing plate 3 is provided with a second pressing plate 4. A T-shaped plate 31 is fixedly connected to one end of the first pressing plate 3 close to the second pressing plate 4. Card slots 32 are opened on both side edges of the T-shaped plate 31. A T-shaped groove 41 adapted to the first pressing plate 3 is opened at one end of the second pressing plate 4. A baffle 42 is fixedly connected inside the T-shaped groove 41. A set of fastening screws 43 are threadedly connected below the baffle 42. The size of the fastening screws 43 is adapted to the card slots 32. A cylinder 10 is fixedly connected to the bottom surface of the operating table 1. The output end of the cylinder 10 is fixedly connected with a limiting device 11. A detachable pressing block 12 is provided at the top end of the limiting device 11;

[0020] By fixedly connecting a T-shaped plate 31 to one end of the first pressing plate 3 and opening card slots 32 on the side edges of the T-shaped plate 31, by placing the T-shaped plate 31 in the T-shaped groove 41 of the second pressing plate 4, and then threading the fastening screws 43 through the card slots 32 and connecting them with the baffle 42 in a threaded manner, at this time, the T-shaped plate 31 can move up and down along the outer wall of the fastening screws 43. Therefore, the height of the first pressing plate 3 and the second pressing plate 4 can be adjusted, and then stainless steel extrusions with different thicknesses can be tightly fixed.

[0021] As Figure 1 shown, a set of first stop bars 8 are provided on the top surface of the operating table 1. Through holes 5 matching the first stop bars 8 are provided at one end of the first pressing plate 3 and the second pressing plate 4 respectively. Through the cooperation of the first stop bars 8 and the through holes 5, when the pressing block 12 presses down on the first pressing plate 3 and the second pressing plate 4, it can prevent the first pressing plate 3 and the second pressing plate 4 from moving left and right due to the shape of the stainless steel extrusion.

[0022] As Figure 1 shown, a sector-shaped groove 6 is provided on one side of each of the first pressing plate 3 and the second pressing plate 4, and a second retaining rod 9 adapted to the sector-shaped groove 6 is fixedly connected to the top surface of the operating table 1. By providing the cooperation between the second retaining rod 9 and the sector-shaped groove 6, when the first retaining rod 8 is inserted into the through hole 5, accurate positioning can be achieved, preventing the first pressing plate 3 and the second pressing plate 4 from swaying left and right during installation.

[0024] As Figure 1 and Figure 5 shown, a washer 121 is fixedly connected to the inner wall of the through port 123. A fastening bolt 13 is provided above the washer 121. One end of the fastening bolt 13 is threadedly connected to the threaded pipe 113. By threadedly connecting the fastening bolt 13 to the threaded pipe 113, the head of the fastening bolt 13 presses the washer 121 to be fixed to the top end of the threaded pipe 113, thereby fixing the pressing block 12 to the limiting device 11.

[0025] As Figure 1 , Figure 4 and Figure 5 shown, the limiting device 11 includes a connecting rod 111. One end of the connecting rod 111 is fixedly connected to the output end of the cylinder 10. The top end of the connecting rod 111 is fixedly connected to a threaded pipe 113. A group of symmetric convex plates 112 are fixedly connected to the outer wall of the threaded pipe 113. A through port 123 is provided on the outer wall of the pressing block 12, and a group of limiting grooves 122 adapted to the convex plates 112 are provided on the inner wall of the through port 123;

[0026] By fixedly connecting a threaded pipe 113 to the top end of the connecting rod 111 and providing a group of convex plates 112 on the pipe wall of the threaded pipe 113 adapted to the limiting grooves 122, and inserting the convex plates 112 into the limiting grooves 122, the pressing block 12 can be positioned, preventing the pressing block 12 from being misaligned with the first pressing plate 3 and the second pressing plate 4 during the downward pressing process of the pressing block 12.

[0027] Working principle of the utility model: When in use, first place the T-shaped plate 31 at one end of the first pressing plate 3 at the T-shaped groove 41 at one end of the second pressing plate 4, and then screw the fastening screw 43 so that one end of the fastening screw 43 passes through the clamping groove 32 and is threadedly connected to the baffle 42, thereby preventing the T-shaped plate 31 from disengaging from the T-shaped groove 41. Immediately afterwards, place the stainless steel extrusion part on the top of the bearing plate 2, and then sleeve the through holes 5 on the first pressing plate 3 and the through holes 5 on the second pressing plate 4 on the corresponding first retaining rod 8. At the same time, it should be noted that the fan-shaped grooves 6 of the first pressing plate 3 and the second pressing plate 4 are stuck on the outer wall of the corresponding second retaining rod 9. After the installation is completed, start the cylinder 10 at this time. Drive the limiting device 11 to move downward through the output end of the cylinder 10, drive the pressing block 12 to move downward through the downward movement of the limiting device 11, drive the first pressing plate 3 and the second pressing plate 4 to press downward through the pressing block 12, and at this time, the stainless steel extrusion part can be fixed.
