Description

Technical Field

[0001] The invention relates to the technical field of pressure vessel weld processing, in particular to pressure vessel weld fine grinding equipment. Background Art

[0002] In the process of manufacturing (small) pressure vessels, different parts or plates need to be connected together by welding to form a complete vessel structure. Therefore, there will be welds on the pressure vessel. For these welds, it is usually necessary to use relevant grinding equipment to finely grind the welds of the pressure vessel to remove the uneven parts of the weld surface;

[0003] The existing grinding equipment usually uses a grinding wheel to remove the uneven parts of the weld surface. When the grinding wheel contacts the weld surface and generates high-speed rotation or friction, since the material at the weld is often hard or has an uneven metal structure, the high-speed friction and collision between the grinding wheel and the metal will cause part of the metal to be cut, melted or vaporized, forming spatter. However, in the prior art, when using a grinding wheel for grinding, since the outer side of the existing grinding wheel is not provided with a corresponding spatter blocking structure, the spatter after grinding will contain sharp metal particles. These particles fly out at high speed and directly hit the eyes, skin or other exposed parts of the workers, causing scratches, burns or other injuries. Moreover, if the spatter is in a free-flying state and is not blocked, it will scatter in the workplace, which not only increases the difficulty of cleaning, but also damages the ground, equipment and other items, and enters the surrounding electrical equipment and machinery, affecting their normal operation.

[0004] In addition, during the fine grinding of the weld surface of the pressure vessel by the grinding wheel, a large amount of heat will be generated at the grinding wheel during friction due to the high-speed rotating friction contact between the grinding wheel and the weld. However, the existing grinding wheel structure is generally simple when fine grinding the weld. When the staff operates it by hand, the accumulated heat can only be naturally cooled by the action of natural wind. If this heat cannot be dissipated in time, the temperature of the grinding wheel will increase, which will affect the hardness and strength of the grinding wheel and even cause the grinding wheel to deform or break. When the grinding wheel is overheated, the contact surface between it and the weld will also change, resulting in uneven grinding or scratches, affecting the flatness and smoothness of the weld.

[0005] In view of this, the present invention proposes a pressure vessel weld fine grinding device to remedy and improve the deficiencies of the prior art. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a pressure vessel weld fine grinding equipment that can block and protect splashes; can collect splashes and prevent backflow; can facilitate subsequent processing of splashes; and can promote airflow to cool the grinding wheel, so as to solve the corresponding technical problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: pressure vessel weld fine grinding equipment, including a body, an output end of which is fixedly connected to a grinding wheel, and further including: a protective blocking mechanism, an intermittent extrusion mechanism, and an airflow promotion mechanism, wherein the protective blocking mechanism, the intermittent extrusion mechanism, and the airflow promotion mechanism are all arranged above the grinding wheel;

[0008] The protective blocking mechanism is used to block the spatter generated when the grinding wheel fine-grinds the weld of the pressure vessel;

[0009] The intermittent extrusion mechanism is used to drive the air flow promotion mechanism while the grinding wheel is fine-grinding the weld of the pressure vessel;

[0010] The wind flow promotion mechanism is used for synchronously moving back and forth in opposite directions while being driven by the intermittent extrusion mechanism to form wind flow.

[0011] Preferably, the protective blocking mechanism includes a bracket fixedly connected to the machine body, and the two ends of the bracket are respectively fixedly connected with a first protective cover and a second protective cover, and the first protective cover half covers the outside of the second protective cover, and the first protective cover and the second protective cover are both arranged above the grinding wheel.

[0012] Preferably, the first protective cover and the second protective cover are both fixedly connected with a fixing frame, and the first protective cover has notches symmetrically formed on the upper end of the side facing the second protective cover.

[0013] Preferably, a collecting rack is movably connected to the inner wall on the side away from the second protective cover, and the collecting rack is used to collect spatters generated when the grinding wheel is fine-grinding the weld of the pressure vessel. The lower end of the collecting rack on the opposite side is fixedly connected to a baffle, and the baffle is used to prevent the spatter from flowing back.

[0014] Preferably, the intermittent extrusion mechanism includes a linkage shaft fixedly connected to the axis of the grinding wheel, L-shaped side plates are symmetrically fixedly connected on both sides of the first protective cover, a driven shaft is rotatably connected between the L-shaped side plates, a cam is symmetrically fixedly connected on the outer surface of the driven shaft, the end of the driven shaft away from the machine body passes through one of the L-shaped side plates, and a transmission member is connected to the linkage shaft between the end of the driven shaft passing through the L-shaped side plate.

[0015] Preferably, the airflow promotion mechanism includes a linkage plate slidably connected between two L-shaped side plates, and the linkage plate is arranged below the driven shaft, and a semicircular protrusion is symmetrically fixedly connected to the top of the linkage plate, and the semicircular protrusion is arranged below the cam, and the cam is used to slide and squeeze the semicircular protrusion.

[0016] Preferably, the bottom of the linkage plate is symmetrically fixedly connected to a first connecting frame, and the wind flow promotion mechanism also includes a wind plate slidably connected to the fixed frame, and the wind plates are distributed in an up and down staggered manner, and wind holes are evenly opened on the wind plates, and an inclined guide plate is fixedly connected to the wind hole.

[0017] Preferably, slides are symmetrically fixedly connected on both sides of the wind plate, and sliding grooves are symmetrically opened on the first protective cover and the second protective cover. The slides are slidably connected in the sliding grooves, and return springs are symmetrically fixedly connected between the two sides of the slide and the groove walls of the sliding grooves.

[0018] Preferably, a second connecting frame is fixedly connected to the top of the slide, and a connecting rod is rotatably connected between the second connecting frame and the first connecting frame.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The first protective cover and the second protective cover provided above the grinding wheel can intercept and block the splashes generated by the high-speed friction and collision between the grinding wheel and the weld, preventing the splashes from continuing to splash onto the eyes, skin or other exposed parts of the workers under the action of force, thereby achieving a protective effect on the workers, thereby preventing the workers from being scratched, burned or otherwise injured. In addition, the splashes are blocked by the two protective covers, which can also prevent the splashes from scattering in the workplace, increasing the difficulty of subsequent cleaning work, causing damage to the ground, equipment and other items, and entering the surrounding electrical equipment and machinery, affecting their normal operation;

[0021] (2) By setting a grinding wheel drive and driving a cam to intermittently squeeze the semicircular protrusion, the two air plates with holes are moved back and forth above the grinding wheel. Different from the existing ventilation and heat dissipation method, the grinding wheel drive can be used to synchronously complete the heat dissipation of the grinding wheel during the fine grinding of the pressure vessel weld by the grinding wheel, thereby avoiding the situation where the grinding wheel temperature rises and affects the hardness and strength of the grinding wheel, or even causes the grinding wheel to deform or break. It can also avoid the situation where the contact surface between the grinding wheel and the weld changes when the grinding wheel is overheated, resulting in uneven grinding or scratches, which affects the flatness and smoothness of the weld. At the same time, the design of this structure can enable mechanical linkage between the structures, thereby eliminating the need for additional energy input, and thus has the advantages of energy saving and environmental protection.

[0022] (3) By utilizing a mechanism linked to the same drive source as the grinding wheel, additional drive devices can be reduced and an integrated design of the system can be achieved. This design not only simplifies the structure of the entire heat dissipation system, but also reduces manufacturing costs and maintenance complexity. Compared with the use of a cooling fan, the reciprocating movement of the two perforated plates will generate less noise and have less impact on the working environment. At the same time, since there is no additional fan motor, the energy consumption of the system will also be reduced accordingly. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Please refer to Figures 1 to 8 As shown, the pressure vessel weld fine grinding equipment includes a body 1, the output end of the body 1 is fixedly connected to a grinding wheel 2, and further includes: a protective blocking mechanism, an intermittent extrusion mechanism, and an airflow promotion mechanism, and the protective blocking mechanism, the intermittent extrusion mechanism, and the airflow promotion mechanism are all arranged above the grinding wheel 2;

[0039] The protective blocking mechanism is used to block the spatter generated when the grinding wheel 2 is fine-grinding the weld of the pressure vessel;

[0040] The intermittent extrusion mechanism is used to drive the air flow promotion mechanism while the grinding wheel 2 is fine-grinding the weld of the pressure vessel;

[0041] The wind flow promotion mechanism is used for synchronously moving back and forth in opposite directions while being driven by the intermittent extrusion mechanism to form wind flow;

[0042] The protective blocking mechanism includes a bracket 301 fixedly connected to the body 1, with a first protective cover 302 and a second protective cover 303 fixedly connected to both ends of the bracket 301, and the first protective cover 302 half covers the outside of the second protective cover 303. The first protective cover 302 and the second protective cover 303 are both arranged above the grinding wheel 2;

[0043] The first protective cover 302 and the second protective cover 303 are both fixedly connected to a fixing frame 304. The upper end of the first protective cover 302 facing the second protective cover 303 is symmetrically provided with a notch 305.

[0044] A collection rack 307 is movably connected to the inner wall of the first protective cover 302 and the second protective cover 303 on the side away from each other. The collection rack 307 is used to collect spatter generated when the grinding wheel 2 fine-grinds the weld of the pressure vessel. A baffle 308 is fixedly connected to the lower end of the collection rack 307 on the side facing each other, and the baffle 308 is used to prevent the spatter from flowing back.

[0045] The effects achieved by this embodiment are as follows: compared with the prior art, the first protective cover 302 and the second protective cover 303 provided above the grinding wheel 2 can intercept and block the splashes generated by the high-speed friction and collision between the grinding wheel 2 and the weld, preventing the splashes from continuing to splash onto the eyes, skin or other exposed parts of the workers under the action of force, thereby achieving a protective effect on the workers, thereby preventing the workers from being scratched, burned or otherwise injured. In addition, the splashes are blocked by the two protective covers, which can also prevent the splashes from scattering in the workplace, increasing the difficulty of subsequent cleaning work, causing damage to the ground, equipment and other items, and entering the surrounding electrical equipment and machinery, affecting their normal operation.

[0046] Further examples:

[0047] Please refer to Figures 1 to 8 As shown, the intermittent extrusion mechanism includes a linkage shaft 401 fixedly connected to the axis of the grinding wheel 2, L-shaped side plates 403 are symmetrically fixedly connected to both sides of the first protective cover 302, a driven shaft 404 is rotatably connected between the L-shaped side plates 403, and a cam 405 is symmetrically fixedly connected to the outer surface of the driven shaft 404. The end of the driven shaft 404 away from the body 1 passes through one of the L-shaped side plates 403, and a transmission member 402 is transmission-connected between the end of the driven shaft 404 passing through the L-shaped side plate 403 and the linkage shaft 401;

[0048] The airflow promotion mechanism includes a linkage plate 501 slidably connected between the two L-shaped side plates 403, and the linkage plate 501 is arranged below the driven shaft 404. A semicircular protrusion 502 is symmetrically fixedly connected to the top of the linkage plate 501, and the semicircular protrusion 502 is arranged below the cam 405. The cam 405 is used to slide and squeeze the semicircular protrusion 502;

[0049] The linkage plate 501 is symmetrically fixedly connected to a first connecting frame 503 at the bottom. The airflow promotion mechanism further includes air plates 508 slidably connected to the fixing frame 304. The air plates 508 are arranged in an upper and lower staggered manner. Air holes 509 are evenly opened on the air plates 508. An inclined guide plate 510 is fixedly connected to the air holes 509.

[0050] Slide plates 506 are symmetrically fixedly connected to both sides of the air plate 508. Slide grooves 306 are symmetrically opened on the first protective cover 302 and the second protective cover 303. The slide plates 506 are slidably connected in the slide grooves 306. Reset springs 507 are symmetrically fixedly connected between both sides of the slide plates 506 and the groove walls of the slide grooves 306.

[0051] The top of the slide 506 is fixedly connected to the second connecting frame 505, and the second connecting frame 505 is rotatably connected to the first connecting frame 503 via a connecting rod 504.

[0052] The effects achieved by this embodiment are as follows: Compared with the prior art, by setting the grinding wheel 2 to drive the cam 405 to intermittently squeeze the semicircular protrusion 502, the two open air plates 508 are moved back and forth above the grinding wheel 2. Different from the existing ventilation and heat dissipation method, the grinding wheel 2 can be used to drive the grinding wheel 2 during the fine grinding of the pressure vessel weld by the grinding wheel 2 to synchronously complete the heat dissipation of the grinding wheel 2, thereby avoiding the temperature increase of the grinding wheel 2 affecting the hardness and strength of the grinding wheel 2, and even causing the grinding wheel 2 to deform or break. It can also avoid the changes in the contact surface between the grinding wheel 2 and the weld when the grinding wheel 2 is overheated, resulting in uneven grinding or scratches, affecting the flatness and smoothness of the weld. At the same time, the design of this structure allows mechanical linkage between structures, thereby eliminating the need for additional energy input, and therefore has the advantages of energy saving and environmental protection.

[0053] The complete usage steps and working principle of the above embodiment are as follows:

[0054] It should be noted that the grinding wheel 2 is a grinding wheel.

[0055] The following is a working process of the protective blocking mechanism to block the spatter generated when the grinding wheel 2 is fine-grinding the weld of the pressure vessel:

[0056] It should be noted that if Figure 1 As shown, the first protective cover 302 and the second protective cover 303 are alternately arranged above the grinding wheel 2 at their facing ends, and two collecting racks 307 are respectively arranged on both sides of the grinding wheel 2, and the bottom height of the grinding wheel 2 is lower than the collecting racks 307. That is, when the grinding wheel 2 contacts the weld of the pressure vessel, the collecting racks 307 will not contact the pressure vessel.

[0057] In the process of fine grinding the weld of the pressure vessel using the grinding equipment, the body 1 is first connected to the power supply, and then the body 1 is held and the power source provided by the body 1 is used to drive the grinding wheel 2 to rotate at a high speed. At this time, according to the location of the weld of the pressure vessel, the grinding wheel 2 can be brought close to the weld and brought into frictional contact with the weld, thereby achieving fine grinding of the weld. The above are all existing technologies and will not be elaborated on here.

[0058] like Figure 1As shown, when the grinding wheel 2 is in contact with the weld, the force exerted by the grinding wheel 2 on the weld causes high-speed friction and collision between the grinding wheel 2 and the weld to cause part of the metal to be cut, melted or vaporized, forming spatter. The first protective cover 302 and the second protective cover 303 provided above the grinding wheel 2 can intercept and block these spatters, preventing the spatters from continuing to splash onto the eyes, skin or other exposed parts of the workers under the action of the force, thereby achieving a protective effect for the workers, thereby preventing the workers from being scratched, burned or otherwise injured. In addition, the spatters are blocked by the two protective covers, which can also prevent the spatters from scattering in the workplace, increasing the difficulty of subsequent cleaning work, causing damage to the ground, equipment and other items, and entering the surrounding electrical equipment and machinery, affecting their normal operation.

[0059] like Figure 1 As shown, since the collecting racks 307 are provided on both sides of the grinding wheel 2, the spatters generated can be collected during the movement of the grinding wheel 2 to fine-grind the weld of the pressure vessel, so as to prevent the spatters from falling back onto the pressure vessel after being blocked by the protective cover, thereby affecting the fine-grinding of the weld. In addition, the baffles 308 installed at the lower ends of the opposite sides of the collecting racks 307 can block the collected spatters during the movement of the collecting rack 307 along with the grinding wheel 2, thereby further reducing the situation in which the collected spatters fall back onto the pressure vessel and affect the processing of subsequent welds by the grinding wheel 2. The collecting rack 307 is movably mounted on the protective cover. After the fine-grinding of the weld of the pressure vessel is completed, the collecting rack 307 can be removed from the protective cover, and the spatters collected inside the collecting rack 307 can be centrally processed for subsequent use.

[0060] The first protective cover 302 half covers the outer side of the second protective cover 303, so that the first protective cover 302 and the second protective cover 303 are arranged in a staggered manner, so that the airflow promotion mechanism mentioned later can operate;

[0061] Please refer to the above working process Figures 1 to 8 .

[0062] The following is a working process in which the intermittent extrusion mechanism operates synchronously with the grinding wheel 2 to finely grind the weld of the pressure vessel, driving the airflow promotion mechanism so that the airflow promotion mechanism synchronously follows the opposite reciprocating movement to form airflow:

[0063] It should be noted that if Figure 1As shown, the transmission member 402 is composed of two transmission wheels and a transmission belt connected between the two transmission wheels, and the two transmission wheels are fixedly connected to the outer surfaces of the ends of the driven shaft 404 and the linkage shaft 401, respectively. When the linkage shaft 401 rotates, the driven shaft 404 can be driven to rotate synchronously, that is, the driving force of the grinding wheel 2 is used to drive the intermittent extrusion mechanism to start operation;

[0064] like Figures 1 to 4 As shown, during the rotation of the grinding wheel 2, the linkage shaft 401 rotates synchronously, and under the transmission action of the transmission member 402, the driven shaft 404 can be driven to rotate synchronously between the two L-shaped side plates 403. Since the cams 405 are symmetrically fixedly connected to the outer surface of the driven shaft 404, and the linkage plate 501 in the air flow promotion mechanism is also slidably connected between the two L-shaped side plates 403, and the two semicircular protrusions 502 symmetrically installed on the linkage plate 501 are located below the two cams 405, when the driven shaft 404 rotates, the cams 405 on it are synchronized with the driven shaft 4 04 is the axis for rotation, and during the rotation of the cam 405, the protruding portion of the cam 405 can contact the surface of the semicircular protrusion 502, and as the cam 405 continues to rotate, the cam 405 will squeeze the semicircular protrusion 502 so that the semicircular protrusion 502 is forced to move downward. At this time, the cam 405 continues to rotate, and the protruding portion of the cam 405 will gradually lose contact with the surface of the semicircular protrusion 502, and the squeezing force on the semicircular protrusion 502 will gradually disappear. The reset movement of the semicircular protrusion 502 and its operating principle are as follows;

[0065] like Figure 2 As shown, the first protective cover 302 and the second protective cover 303 are both mounted with a fixing frame 304, and the fixing frame 304 is slid with a wind plate 508, and the wind plate 508 is as shown in FIG. Figure 3As shown, the slide plates 506 are symmetrically arranged on both sides, and the slide plates 506 slide in the slide grooves 306. The top of the slide plate 506 and the bottom of the linkage plate 501 are rotatably connected by the first connecting frame 503 and the second connecting frame 505. The connecting rod 504 is connected. When the semicircular protrusion 502 is squeezed and moved downward by the protruding part of the cam 405, the linkage plate 501 moves downward synchronously, so that the first connecting frame 503 installed at the bottom of the linkage plate 501 moves downward synchronously. Under the linkage action of the connecting rod 504, the two slide plates 506 on the same horizontal axis can be driven to move in opposite directions. At this time, Since return springs 507 are symmetrically arranged between the slide plate 506 and the slide groove 306, when the slide plate 506 moves in the opposite direction, the return spring 507 can be squeezed outward, so that the return spring 507 on the opposite side can be stretched. As the cam 405 continues to rotate, the resistance of the semicircular protrusion 502 disappears, and the slide plate 506 can be moved towards each other and reset under the action of the compressed return spring 507. This reciprocating movement can make the two wind plates 508 staggered in the upper and lower directions move back and forth. Moreover, because the wind plates 508 are evenly provided with air holes 509, and the air holes 509 are fixed with inclined guide plates 510, as shown in FIG. Figure 8 As shown, when the two plates with holes move back and forth laterally, the relative movement between them will affect the wind flow, causing the space between them to gradually decrease, thereby compressing the air therein, causing the air to be compressed and pass through the air holes 509. These openings allow the wind flow to pass through the plate surface more easily, increasing the fluidity of the wind flow. Therefore, when the plate moves, it will help push the wind flow through the air holes 509. At this time, the wind flow that passes through will flow to the surface of the grinding wheel 2 below, promoting the wind flow that the grinding wheel 2 contacts, so that the air flow around the grinding wheel 2 can be accelerated to circulate and take away the heat on the grinding wheel 2 (when the air flow speed increases, the heat it takes away also increases accordingly, because heat transfer is proportional to the fluid speed). Proportional), thereby achieving heat dissipation of the grinding wheel 2 below. This design is different from the existing ventilation heat dissipation method. During the process of fine grinding of the pressure vessel weld by the grinding wheel 2, the driving of the grinding wheel 2 can be used to synchronously complete the heat dissipation of the grinding wheel 2, thereby avoiding the temperature increase of the grinding wheel 2 affecting the hardness and strength of the grinding wheel 2, and even causing the grinding wheel 2 to deform or break. In addition, it can also avoid the change of the contact surface between the grinding wheel 2 and the weld when the grinding wheel 2 is overheated, resulting in uneven grinding or scratches, thereby affecting the flatness and smoothness of the weld. At the same time, the design of this structure can enable mechanical linkage between the structures, thereby eliminating the need for additional energy input, and thus has the advantages of energy saving and environmental protection.

[0066] In addition, the use of two air plates 508 with openings for reciprocating motion in opposite directions is different from the existing method of using a cooling fan for the grinding wheel 2. The plate structure can be used to cool the grinding wheel 2 while the grinding wheel 2 is running, without the need for additional energy input. Not only is the structure relatively simple, but the equipment maintenance cost is also low, and the problem of heat accumulation that still exists in the use of the existing cooling fan is effectively avoided, reducing the maintenance and repair of the cooling fan. Moreover, through the two opening plates moving in opposite directions, the air flow can flow more evenly over the surface of the grinding wheel 2. This design can ensure that different parts of the grinding wheel 2 can be effectively cooled. The heat dissipation can be improved to avoid overheating in some areas and insufficient heat dissipation in other areas. In contrast, the heat dissipation effect of the cooling fan may deviate due to the unevenness of wind direction or wind speed. By utilizing the mechanism of linkage with the same drive source as the grinding wheel 2, the additional drive device can be reduced to achieve the integrated design of the system. This design not only simplifies the structure of the entire heat dissipation system, but also reduces the manufacturing cost and maintenance complexity. Compared with the use of a cooling fan, the reciprocating movement of the two perforated plates will generate less noise and have less impact on the working environment. At the same time, since there is no additional fan motor, the energy consumption of the system will be reduced accordingly.
