Description

Technical Field

[0001] This utility model relates to the field of pipe end grinding technology, specifically a pipe end grinding device for processing stainless steel pipes. Background Technology

[0002] Patent application number 202421777917.8 discloses a grinding device for the end of a heating universal round pipe. It comprises a worktable, processing slots, a clamping mechanism, and a reciprocating grinding mechanism. Multiple processing slots are created on the worktable. When grinding is required, the operator places multiple workpieces inside the processing slots, and the clamping mechanism clamps and secures the workpieces. The operator starts the grinding motor, causing the output of the motor to rotate the grinding head. The reciprocating grinding mechanism then drives the grinding motor and grinding head to reciprocate and grind the workpieces. This ensures the operator's grinding efficiency and solves the problem that in practical use, the aforementioned equipment can only process a single pipe, thus limiting the operator's ability to grind multiple pipes simultaneously, reducing work efficiency and achieving the effect of grinding multiple workpieces.

[0003] However, the burrs or debris generated during the grinding process by the aforementioned grinding device will gradually move to the edge of the pipe opening. Since the grinding head is directly facing the pipe end, it is difficult to clean the inner and outer edges of the pipe opening. Based on this, a port grinding device for processing stainless steel pipe fittings is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a port grinding device for processing stainless steel pipe fittings, which can grind the inner and outer edges of pipe fitting ports and openings, saving more time and effort; moreover, it can grind the edges of pipe fittings of various sizes, better meeting actual usage needs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a port grinding device for processing stainless steel pipe fittings, comprising a connecting shaft and a grinding disc fixed to the head end of the connecting shaft, wherein a grinding mechanism for polishing the inner and outer edges of the stainless steel pipe fittings is sleeved on the connecting shaft. The edge grinding mechanism includes a movable sleeve that is detachably installed on the outer end of the connecting shaft, and at least two sets of support plates are distributed along its circumference at the front end of the movable sleeve. The support plate is slidably mounted with several sets of movable rods at intervals along its length. The tail end of the movable rod protrudes outward to prevent it from falling off the head end of the support plate. A grinding rod is installed at the head end of the movable rod, and a spring is sleeved on the movable rod at the position between the support plate and the grinding rod. A through hole is opened on the grinding disc at the position of the grinding rod.

[0006] Preferably, the first end of the moving rod is fixed with a screw, and the tail end of the grinding rod is provided with a screw hole that cooperates with the screw.

[0007] Preferably, a bolt is provided between the movable sleeve and the connecting shaft to fix the two together.

[0008] Preferably, a locking element is provided between the movable sleeve and the connecting shaft. The locking element includes a limiting hole opened on the side wall of the connecting sleeve and an elastic button installed on the connecting shaft to cooperate with the limiting hole.

[0009] Preferably, the support plate has an opening through which the moving rod passes laterally.

[0010] Preferably, in the initial state, the leading ends of several sets of grinding rods pass through the through holes and partially extend out of the leading end face of the grinding disc.

[0011] This utility model provides a device for grinding the ends of stainless steel pipe fittings, which has the following advantages compared with the prior art: 1. This utility model, by setting up a grinding mechanism, has the first end of the grinding disc pressing into contact with the pipe end. During this process, the pipe end will press the grinding rod in contact with it towards the tail end into the through hole; at the same time, the adjacent grinding rods that are not pressed into the through hole will contact the outer and inner edges of the pipe end. As the grinding disc rotates, the grinding rods also rotate simultaneously, thus realizing the grinding of the inner and outer edges of the pipe end and the pipe opening, which is more time-saving and labor-saving; moreover, it can realize the grinding of pipes of various sizes, which can better meet the actual use needs.

[0012] 2. This utility model features a detachable movable sleeve and grinding rod. When the grinding disc or grinding rod is damaged, the movable sleeve can be pulled out from the end of the connecting shaft, allowing the support plate, movable rod, spring, and grinding rod to be removed as a whole and then installed on a new grinding disc, avoiding waste caused by discarding the whole assembly. Moreover, when a single grinding rod is damaged, it can be unscrewed and replaced with a new one, achieving cost savings. Attached Figure Description

Detailed Implementation

[0015] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0016] Example 1 Current grinding heads are typically disc-shaped blocks that rotate to grind the ends of stainless steel pipes. However, since the grinding block is directly facing the pipe end, metal burrs or debris generated during grinding are pushed to the outer and inner edges of the pipe end. This usually requires separate grinding of the inner and outer edges of the pipe end, making the process cumbersome, time-consuming, and labor-intensive. This embodiment provides a device for grinding the ends of stainless steel pipe fittings. Figures 1-6 As shown, it includes a connecting shaft 1 and a grinding disc 2 fixed to the head end of the connecting shaft 1. A grinding mechanism 3 for polishing the inner and outer edges of stainless steel pipe fittings is sleeved on the connecting shaft 1. By installing the connecting shaft 1 on the grinding device, the grinding disc 2 can be installed. While the grinding disc 2 rotates and grinds, the grinding mechanism 3 can also grind the inner and outer edges of the pipe opening, eliminating the need to grind the inner and outer edges of the pipe opening separately, thus saving time and effort.

[0017] The following solutions are provided to address the issue of simultaneously grinding the pipe fitting ports and the inner and outer edges of the pipe openings: The edge grinding mechanism 3 includes a movable sleeve 31 detachably mounted on the outer end of the connecting shaft 1. The movable sleeve 31 is adapted to the connecting shaft 1. At least two sets of support plates 32 are distributed along its circumference at the head end of the movable sleeve 31. It can be configured to have two, three, or four sets, as detailed in the reference. Figure 6The support plate 32 is slidably mounted with several sets of moving rods 33 at intervals along its length (the support plate 32 has an opening 37, and the moving rods 33 pass through the opening 37 laterally). The tail end of the moving rod 33 protrudes outward to prevent it from falling off the head end of the support plate 32. That is, the size of the protruding part is larger than the size of the opening 37. A grinding rod 34 is installed at the head end of the moving rod 33, and a spring 35 is sleeved on the moving rod 33 at the position between the support plate 32 and the grinding rod 34. The grinding disc 2 has a through hole 36 at the position corresponding to the grinding rod 34. The inner diameter of the through hole 36 is slightly larger than the outer diameter of the grinding rod 34.

[0018] During use, the grinding device pushes the grinding disc 2 or the pipe to move, causing the front end of the grinding disc 2 to press against the pipe end. During this process, the pipe end will press the grinding edge rod 34 in contact with it towards the rear end into the through hole 36, so that its end face contacts the front end face of the grinding disc 2. At the same time, the adjacent grinding edge rod 34 that is not pressed into the through hole 36 will contact the outer surface (including the outer edge) and inner surface (including the inner edge) of the pipe end. As the grinding disc 2 rotates, the grinding edge rod 34 also rotates at the same time, which can achieve grinding of the inner and outer edges of the pipe end and the pipe opening, eliminating the need to grind the inner and outer edges of the pipe opening separately, saving more time and effort. Moreover, it can achieve grinding of pipes of various sizes, which can better meet the actual use needs. When the grinding disc 2 or the pipe moves away from each other, the compressed spring 35 returns to its original state, which will cause the grinding rod 34, which was squeezed into the through hole 36, to extend back to its original position.

[0019] A screw 38 is fixed at the head end of the moving rod 33, and a screw hole 39 for cooperating with the screw 38 is opened at the tail end of the grinding rod 34. A bolt 4 is provided between the moving sleeve 31 and the connecting shaft 1 to fix the two together.

[0020] When the grinding disc 2 or the edge grinding rod 34 is damaged, unscrew the bolt 4 to pull the movable sleeve 31 out from the tail end of the connecting shaft 1. Then, the support plate 32, the movable rod 33, the spring 35, and the edge grinding rod 34 can be removed as a whole and installed on the new grinding disc 2, avoiding the waste caused by discarding the whole thing. Moreover, when a single edge grinding rod 34 is damaged, it can also be unscrewed and replaced with a new one, achieving the purpose of saving costs.

[0021] In this embodiment, in the initial state, the heads of several sets of grinding rods 34 pass through the through holes 36 and partially extend out of the head end face of the grinding disc 2.

[0022] Example 2 Basically the same as in Example 1, such as Figure 7As shown, the difference lies in the fact that a locking element 5 is provided between the movable sleeve 31 and the connecting shaft 1. The locking element 5 includes a limiting hole 51 formed on the side wall of the connecting sleeve and an elastic button 52 installed on the connecting shaft 1 to cooperate with the limiting hole 51. When it is necessary to remove the movable sleeve 31 and its components, press the elastic button 52 inward to disengage it from the limiting hole 51, and then the movable sleeve 31 can be removed from the connecting shaft 1. Compared with the bolt 4 in Embodiment 1, the locking element 5 in this embodiment enables quick installation and removal between the movable sleeve 31 and the connecting shaft 1.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
