Description

Technical Field

[0001] This utility model relates to the field of stainless steel bar processing technology, and more specifically, to a stainless steel bar fixing clamp. Background Technology

[0002] The main characteristics of stainless steel are its rust resistance and corrosion resistance. It contains at least 10.5% chromium and a maximum of 1.2% carbon. It is an abbreviation for stainless and acid-resistant steel. Steels resistant to weak corrosive media such as air, steam, and water, or those possessing rust-resistant properties, are called stainless steel. Steels resistant to chemical corrosion media (acids, alkalis, salts, etc.) are called acid-resistant steel. Due to differences in their chemical composition, their corrosion resistance differs. Ordinary stainless steel is generally not resistant to chemical corrosion, while acid-resistant steel generally possesses rust resistance. Better grades also contain nickel, and the addition of molybdenum can further improve atmospheric corrosion resistance, especially resistance to chloride-containing atmospheres. Some stainless steels have a higher hardness than aluminum alloys, but their cost is also higher. Stainless steel bars require positioning and clamping during processing.

[0003] When stainless steel parts need to be moved, the clamping and moving devices need to be adjusted and then pulled to transport and move them, resulting in low conveying efficiency of stainless steel parts.

[0004] A search revealed that Chinese patent CN222779164U discloses a fixing clamp for processing stainless steel bars. When stainless steel bars need to be transported, a cylinder is activated to disengage the inner ring of the friction plate from the outer side of the bar, thereby loosening the bar. Then, through a screw mechanism, an arc-shaped plate is disengaged from the outer side of the bar, further loosening the bar. Finally, a motor is activated, which drives the first conveying roller to rotate, allowing the bar to drive a rotating ball to rotate inside the first flexible plate, thus facilitating the transportation and movement of the bar by the operator.

[0005] In actual use, the aforementioned stainless steel bar clamping device typically uses single-point or double-point clamping when clamping the bar, which can lead to localized stress concentration, resulting in bending deformation. Furthermore, the small contact area between the clamping device and the bar makes it difficult to provide sufficient friction to prevent the bar from slipping out. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a stainless steel bar clamp to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A stainless steel bar clamp includes a base, a support seat fixedly connected to the top of the base, a first bidirectional screw rotatably connected inside the base, a first turntable fixedly connected to one end of the first bidirectional screw, two connecting frames threaded to the outer side of the first bidirectional screw, limit components installed on the connecting frames, and a support mechanism installed on the support seat.

[0009] The limiting component includes a first fixed ring, a fixed frame fixedly connected inside the first fixed ring, multiple guide rods fixedly connected to one side of the fixed frame, a threaded rod rotatably connected inside the fixed frame, a second turntable fixedly connected to one end of the threaded rod, a movable ring threadedly connected to the outer side of the threaded rod, the movable ring slidably connected to the outer side of the guide rod, a push rod fixedly connected to one side of the movable ring, a slider fixedly connected to one end of the push rod, multiple movable rods slidably connected inside the fixed frame, a groove opened at one end of the movable rod, the inner side of the groove slidably connected to the slider, and a second fixed ring fixedly connected to the other end of the movable rod.

[0010] By adopting the above technical solution, multi-point contact clamping can be formed on the outside of the bar, which can effectively prevent the bar from slipping or axial displacement and ensure the stability of the processing.

[0011] As a further description of the above technical solution: the support mechanism includes a second bidirectional screw, which is rotatably connected to the inside of the support base. A third turntable is fixedly connected to the top of the second bidirectional screw. An upper fixing block is threadedly connected to the outside of the second bidirectional screw. A guide post is fixedly connected to one side of the upper fixing block. A lower fixing block is threadedly connected to the outside of the second bidirectional screw. A guide cylinder is fixedly connected to one side of the lower fixing block. The inside of the guide cylinder is slidably connected to the outside of the guide post.

[0012] By adopting the above technical solution, additional support points can be provided on the outside of the bar, which can reduce stress concentration at a single point.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting a limiting component, compared with the existing technology, the push rod can push the moving rod through the tangential surface to drive the fixed ring to fit against the outside of the bar, thereby enabling multi-point contact clamping on the outside of the bar. This can evenly distribute the clamping force on the circumference of the bar, effectively reduce the bending or twisting deformation of the bar due to uneven force, and effectively prevent the bar from slipping or axial displacement, ensuring the stability of the processing process.

[0015] 2. By setting up a support mechanism, compared with the existing technology, the upper and lower fixed blocks move relatively stably, and the "V" shaped cut surface contacts the outside of the bar, thereby providing additional constraint points on the outside of the bar. The bar is divided into segments with the two limiting components, which can reduce stress concentration at single points and help increase the rigidity of the bar. Attached Figure Description

[0024] 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.

[0025] The embodiments disclosed in this application are as follows: Figures 1-7The stainless steel bar clamp shown includes a base 1, a support seat 2 fixedly connected to the top of the base 1, a first bidirectional screw 4 rotatably connected inside the base 1, a first turntable 5 fixedly connected to one end of the first bidirectional screw 4, two connecting frames 3 threadedly connected to the outside of the first bidirectional screw 4, limit components installed on the connecting frames 3, and a support mechanism installed on the support seat 2.

[0026] The limiting assembly includes a fixed ring 6, a fixed frame 7 fixedly connected inside the fixed ring 6, multiple guide rods 8 fixedly connected to one side of the fixed frame 7, a threaded rod 9 rotatably connected inside the fixed frame 7, a second turntable 10 fixedly connected to one end of the threaded rod 9, a movable ring 11 threadedly connected to the outer side of the threaded rod 9, the movable ring 11 slidably connected to the outer side of the guide rod 8, a push rod 12 fixedly connected to one side of the movable ring 11, a slider 13 fixedly connected to one end of the push rod 12, multiple movable rods 14 slidably connected inside the fixed frame 7, a groove 15 opened at one end of the movable rod 14, the inner side of the groove 15 slidably connected to the slider 13, and a fixed ring 12 fixedly connected to the other end of the movable rod 14. 6. The rotation of the threaded rod 9 causes the threaded rod 9 to drive the moving ring 11 to move multiple push rods 12. Multiple guide rods 8 can provide guidance for the movement of the moving ring 11, so that the multiple push rods 12 can push the moving rod 14 to move. The cross-sections of one side of the push rod 12 and one side of the moving rod 14 are adapted to each other, and the push rod 12 can drive the slider 13 to slide inside the groove 15. Thus, the push rod 12 can push the moving rod 14 to drive the fixed ring 16 to contact the outside of the bar. Multi-point contact clamping can be performed on the outside of the bar, which can effectively reduce the bending or twisting deformation of the bar due to uneven force, thereby ensuring the stability of the processing.

[0027] Reference Figure 6 As shown, the support mechanism includes a second bidirectional screw 17, which is rotatably connected to the support base 2. A third turntable 18 is fixedly connected to the top of the second bidirectional screw 17. An upper fixing block 19 is threadedly connected to the outer side of the second bidirectional screw 17. A guide post 20 is fixedly connected to one side of the upper fixing block 19. A lower fixing block 21 is threadedly connected to the outer side of the second bidirectional screw 17. A guide cylinder 22 is fixedly connected to one side of the lower fixing block 21. The inside of the guide cylinder 22 is slidably connected to the outside of the guide post 20. By rotating the second bidirectional screw 17, the upper fixing block 19 and the lower fixing block 21 can be driven to move relative to each other. Through the slidable connection between the guide post 20 and the inside of the guide cylinder 22, the upper fixing block 19 and the lower fixing block 21 can move stably so that the "V" shaped cut surface contacts the outside of the bar. This provides an additional constraint point in the middle of the bar and reduces stress concentration at a single point.

[0028] Working principle of this utility model: This utility model designs a stainless steel bar fixing clamp, the specific structure of which is shown in the attached instruction manual. Figures 1-7As shown, in this technical solution, through the cooperation between various structures, when it is necessary to fix and clamp the stainless steel bar, the bar is first inserted between the two fixing rings 6. Then, the first turntable 5 is rotated, so that the first turntable 5 can drive the first bidirectional screw 4 to rotate. Utilizing the opposite thread direction on the outer side of the first bidirectional screw 4, the first bidirectional screw 4 can drive the two connecting frames 3 to move relative to each other through the thread, thereby allowing adjustment according to the length of the bar. After adjusting the distance between the two connecting frames 3, the second turntable 10 is rotated, so that the second turntable 10 can drive the threaded rod 9 to rotate, so that the threaded rod 9 drives the moving ring 11 to move on the fixing ring 6 through the thread. Multiple guide rods 8 can provide guidance for the movement of the moving ring 11. The moving ring 11 can push multiple push rods 12 to squeeze one end of the moving rod 14, pushing... One end of rod 12 is matched with the end of moving rod 14, and slider 13 is slidably connected to the inner side of slide groove 15, so that multiple push rods 12 can squeeze and push moving rod 14 to move inside fixed frame 7, so that multiple moving rods 14 can drive fixed ring 16 to clamp and limit the outer side of the rod, so as to fix the rod. Then, the third turntable 18 is rotated, and the third turntable 18 drives the second bidirectional screw 17 to rotate. The opposite thread direction on the outer side of the second bidirectional screw 17 allows the second bidirectional screw 17 to drive the upper fixed block 19 and the lower fixed block 21 to move relative to each other through the thread. The guide post 20 is slidably connected to the inner side of guide cylinder 22, so that the upper fixed block 19 and the lower fixed block 21 can move stably relative to each other, so as to clamp and support the outer side of the rod through the "V" shaped cut, so that the rod can remain stable.
