Description

Technical Field

[0001] This utility model relates to the field of steel pipe deburring technology, specifically to an automated deburring device for the end face of stainless steel pipes. Background Technology

[0002] Stainless steel pipe fittings are hollow, long, round steel materials, mainly used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as mechanical structural components. After the stainless steel pipe fittings are manufactured, they need to be ground to remove the burrs on their end faces.

[0003] Existing automated deburring machines for stainless steel pipe ends generally only apply pressure and restraint to the top of the stainless steel pipe during rotation, and do not apply pressure and restraint to the two ends of different stainless steel pipes during rotation. This results in poor stability and also makes it easy for the stainless steel pipes to move or detach during grinding and polishing.

[0004] For example, the automated deburring device for the end face of stainless steel pipes disclosed in Chinese Patent Publication No. CN220575458U, through optimized design, allows the rotating rollers on the device to drive the upper stainless steel pipe for deburring while rotating. The first and second telescopic rods on both sides of the telescopic cylinder at the top of the stainless steel pipe are also bound to both ends of the rotating stainless steel pipe via binding rods connected to their lower ends. This binds the stainless steel pipe at both ends during grinding on the upper end of the rollers, preventing it from shifting outwards and falling off. Simultaneously, multiple sets of steel balls arranged inside the binding rods increase the stability of the stainless steel pipe during rotation without affecting its rotation. Furthermore, the adjustable extension length of the first and second telescopic rods, locked by clamping screws, allows the binding assembly at the upper end of this processing device to adapt to various sizes of stainless steel pipes.

[0005] However, in actual deburring processes, the aforementioned device requires repeated installation before and after a single steel pipe, which means that the restraint rod and roller need to be reinstalled and disassembled. Furthermore, when removing burrs from steel pipes with different inner diameters, the inner diameter of the roller needs to be adaptively adjusted. In addition, there are non-standard steel pipes. Once such a type of steel pipe appears, the roller needs to be redesigned, making it impossible to achieve rapid deburring of steel pipes. Adjustability and adaptability both need to be improved. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an automated deburring device for the end face of stainless steel pipes, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automated deburring device for stainless steel pipe ends, comprising a processing base, characterized in that: a vertical plate is fixedly mounted on the processing base, and rotating grooves are provided at the four apex corners of one end of the plate. Each rotating groove contains a corresponding rotating rod, and each rotating rod is welded with a transmission disc for friction transmission. The transmission disc is connected to a circular insertion seat via friction transmission. An opening for the steel pipe to pass through is provided at the center of the insertion seat, and a rotating shaft is rotatably mounted on the outer end face of the insertion seat. A [missing information - likely a device or component] is engaged on the rotating shaft. The mounting roller has a grinding disc inside it. The rotating rod drives the transmission disc to rotate. Due to friction, the non-fixed insertion seat rotates periodically. The rotating shaft on the insertion seat and the grinding disc inside the mounting roller follow the circumferential motion. Finally, the end face of the steel pipe inserted into the opening can be fully and thoroughly ground by the grinding disc without dead angles. This achieves automated deburring while avoiding dead angles. Furthermore, the opening design of the insertion seat allows the steel pipe to be ground and deburred during the transmission and penetration process. This is suitable for most assembly line production modes, improving deburring efficiency and practicality.

[0008] A further improvement of this utility model is that, in order to ensure the stability of the insertion seat during rotation, abutment rollers are symmetrically arranged on one end of the upright plate where the rotating rod is located. The abutment rollers have a limiting opening in the middle for placing the insertion seat, and the insertion seat is slidably connected to the abutment rollers through the limiting opening. The abutment rollers provide fulcrum support to the insertion seat through the limiting opening, ensuring the periodic rotation of the insertion seat.

[0009] A further improvement of this utility model is that, in order to ensure the simultaneous rotation of the rotating rods and simplify the corresponding transmission structure, one end of each rotating rod passes through a rotating groove and is connected to a corresponding transmission wheel. Each transmission wheel is connected to the same transmission belt. The rotating rod is fixedly connected to the transmission wheel, and one of the rotating rods is connected to a drive motor through a coupling.

[0010] A further improvement of this utility model is that, in order to further enhance the polishing effect of the polishing disc, multiple sets of deburring protrusions are arranged in an array on the outer end face of the polishing disc, and each of the deburring protrusions is welded to the polishing disc.

[0011] A further improvement of this utility model is that, in order to achieve automated deburring of steel pipes with different inner diameters, a steel pipe body is installed inside the opening of the through-hole seat. Replaceable clamping rings are installed at both the front and rear ends of the steel pipe body. Lifting blocks are symmetrically arranged on both sides of the clamping rings. The lifting blocks are installed in the sliding groove of a sliding seat, which is vertically fixed on the processing seat. The lifting blocks are slidably connected to the sliding seat through the sliding groove. Furthermore, the height of the lifting blocks is controlled by an electrically controlled push rod, which adjusts the lifting blocks in the sliding groove to different longitudinal positions. This ensures that steel pipes with different inner diameters are accurately connected to the circular position of the through-hole seat for transmission or fixed grinding, improving the compatibility and adjustability of the automated deburring process for steel pipes.

[0012] A further improvement of the present invention is that: an electrically controlled push rod is vertically fixed in the sliding groove, and the electrically controlled push rod and the lifting block are limited by fasteners; and a hollow groove corresponding to the opening is opened at the center of the upright plate.

[0013] Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are: by periodically rotating the non-fixed insertion seat, the rotating shaft set on the insertion seat and the grinding disc sleeved inside the roller installed on it follow the circumferential movement, and finally the end face of the steel pipe inserted into the opening can be fully and without dead angles by the grinding disc, realizing automated deburring while avoiding the occurrence of grinding dead angles. In addition, the opening design of the insertion seat allows the steel pipe to be ground and deburred during the transmission and penetration process, which is suitable for most assembly line production modes, improving deburring efficiency and practicality.

[0015] By controlling the height of the electric push rod, the lifting block in the sliding groove is adjusted to different longitudinal positions, ensuring that steel pipes of different inner diameters are accurately connected to the circular position for transmission or fixed grinding, thus improving the compatibility and adjustability of automated deburring of steel pipes.

Each transmission wheel 11 is connected to the same transmission belt 12. The rotating rod 3 is fixedly connected to the transmission wheel 11, and one of the rotating rods 3 is connected to a drive motor 13 through a coupling.

[0028] To further enhance the polishing effect of the polishing disc 9, multiple sets of deburring protrusions 14 are arranged in an array on the outer end face of the polishing disc 9, and each deburring protrusion 14 is welded to the polishing disc 9.

[0029] Example 2: In order to achieve automated deburring of steel pipes with different inner diameters, a steel pipe body 15 is installed in the opening 6 of the through seat 5. The front and rear ends of the steel pipe body 15 are equipped with replaceable clamping rings 16. Lifting blocks 17 are symmetrically arranged on both sides of the clamping rings 16. The lifting blocks 17 are set in the sliding groove of a sliding seat 18. The sliding seat 18 is vertically fixed on the processing seat 1. The lifting blocks 17 are slidably connected to the sliding seat 18 through the sliding groove.

[0030] Furthermore, in this embodiment, the height control of the electric push rod 19 drives the lifting block 17 in the sliding groove to complete the adjustment of different longitudinal positions, ensuring that steel pipes of different inner diameters are accurately connected to the circular position of the seat 5 for transmission or fixed grinding, thereby improving the compatibility and adjustability of the automated deburring process of steel pipes.

[0031] An electrically controlled push rod 19 is vertically fixed inside the sliding groove, and the electrically controlled push rod 19 is connected to the lifting block 17 by fasteners. A hollow groove corresponding to the opening 6 is opened at the center of the upright plate 2.
