Technical Field

[0001] The present invention relates to the technical field of barbecue grill grinding, and particularly relates to a grinding device for the production of barbecue grills. Background Art

[0002] Commercial barbecue grills are high-efficiency cooking equipment designed for commercial places, mainly used for large-scale production of grilled skewers, meats, vegetables and other barbecue foods. They are divided into charcoal barbecue grills, gas barbecue grills, and electric barbecue grills according to the heat source. Their outer shells are usually welded by stainless steel. After welding, there are often defects such as unevenness and weld beads in the weld area. Therefore, it is necessary to grind the welded joints to restore the surface flatness, reduce stress concentration, and prevent structural failure caused by excessive local stress. Moreover, rough welds will affect the process effects of polishing, electroplating, etc. Grinding to a specific roughness is a necessary preprocessing step for precision surface treatment.

[0003] A patent document with the publication number CN115741330B discloses a grinding device for the production of stainless steel equipment, which includes a workbench. There are feeding components on both side walls of the workbench. There is a welding component on one side of the feeding component. There are fixing components around the welding component and a first material taking component below the welding component. There is a grinding component on one side of the welding component. There is a second material taking component on one side of the grinding component. There is a blanking component on the side of the workbench close to the second material taking component. There is a finished product box on one side of the blanking component. The grinding component includes a grinding lead screw, which is rotatably arranged on both side walls of the workbench. There is a grinding limit shaft above the grinding lead screw, and the grinding limit shaft is fixedly connected to both side walls of the workbench. A grinding slider is sleeved outside the grinding lead screw, and the grinding slider is in threaded cooperation with the grinding lead screw. The grinding limit shaft penetrates and is in sliding cooperation with the grinding slider. A grinding conversion box is fixedly arranged on the bottom surface of the grinding slider. A grinding motor is fixedly arranged on the outer wall of one side of the workbench, and the output shaft of the grinding motor passes through one side wall of the workbench and is fixedly connected to the grinding lead screw. It automatically grinds the stainless steel equipment.

[0004] However, there are still the following problems in this solution. Although it can achieve automatic grinding, it cannot grind the welds of the finished product box body that has been welded. In addition, there are inner corner welds and outer corner welds on the finished barbecue grill equipment. Conventional grinding devices in the prior art are not convenient for grinding the inner corner welds and outer corner welds on the finished product equipment at the same time, or cannot cover the welding area during grinding, affecting the grinding quality. Summary of the Invention

[0005] The present invention provides a grinding device for the production of barbecue grills, aiming to solve the problem in the related art that it is not convenient to grind the inner corner welds and outer corner welds on the finished product equipment at the same time.

[0006] The grinding device for the production of barbecue grills of the present invention includes a grinding belt installed on an installation frame, and a driving component and a guiding component are arranged on the installation frame; The driving assembly is connected to the grinding belt to drive the grinding belt to move back and forth; The guide assembly includes a guide frame, a hydraulic component, a guide rod, and a spring piece. The guide frame is filled with hydraulic oil. The hydraulic component cooperates with the guide frame to adjust the oil pressure in the guide frame. The guide rod and the guide frame are slidably matched, and one end of the guide rod extends into the guide frame, and the other end is connected to the spring piece. A plurality of guide rods are arranged in a plane perpendicular to the weld. The guide rod slides in the direction toward the weld, and the spring piece 1 slides and abuts against the side of the grinding belt away from the weld. The hydraulic parts adjust the oil pressure in the guide frame to increase, and the increased oil pressure is evenly distributed on multiple guide rods so that the multiple guide rods move synchronously close to the weld. Once the spring piece is deformed and abuts against the plates on both sides of the weld, the grinding belt is driven to fit tightly against the outside of the weld.

[0007] The effect is that the mounting frame is moved to the weld, and then the hydraulic parts are adjusted to increase the pressure of the hydraulic oil in the guide frame, driving the multiple guide rods on the guide frame to move toward the direction of the weld at the same time, and the guide rod drives the spring piece 1 to move, and the spring piece 1 drives the corresponding grinding belt part close to the weld until the spring piece 1 moves to abut the plates on both sides of the weld, and at the same time drives the grinding belt to abut the weld, the spring piece 1 is deformed when it abuts the plate, and the grinding belt is clamped between the weld and the spring piece 1, and then the driving component drives the grinding belt to reciprocate to grind the weld, by adjusting the positions of the multiple guide rods before grinding, and at the same time, under the action of the spring piece 1, the grinding belt is pressed on the weld at the inner corner or the weld at the outer corner to grind the weld, thereby improving the grinding efficiency of the weld.

[0008] Preferably, the hydraulic parts include a cylinder, a push rod, a press sleeve 1 and a press sleeve 2. The press sleeve 1 and the press sleeve 2 are both arranged in a guide frame. Push plates are slidably installed in the press sleeve 1 and the press sleeve 2. One end of the push rod is connected to the output end of the cylinder, and the other end is connected to the push plate in the press sleeve 1. The press sleeve 2 is arranged on the outside of the guide rod, and the guide rod is connected to the push plate in the press sleeve 2. When the push rod moves close to the guide frame, the push plate in the press sleeve 1 moves and simultaneously increases the pressure in the guide frame, so as to drive the push plate and the guide rod in the press sleeve 2 to move toward the outside of the guide frame.

[0009] The effect is that the cylinder drives the push rod to move toward the inside of the guide frame, and the movement of the push rod drives the push plate in the pressure sleeve 1 to move toward the inside of the guide frame, squeezing the hydraulic oil in the guide frame to increase the pressure of the hydraulic oil in the guide frame, driving the push rod in the pressure sleeve 2 to move toward the outside of the guide frame, and then driving the guide rod to move to adjust the position of the guide rod. The pressure sleeves 2 corresponding to the multiple guide rods are all connected to the inside of the guide frame. When the pressure of the hydraulic oil in the guide frame increases, and when the guide rod drives the spring sheet 1 to abut against the plates on both sides of the weld, the pressures applied by the multiple guide rods on the spring sheet 1 are the same, so that the pressures applied to the weld at various locations on the grinding belt are the same, so as to improve the uniformity of the welding of the weld.

[0011] The effect is that the driving member drives the driving roller to rotate back and forth, and the reciprocating rotation of the two driving rollers drives the grinding belt to be alternately wound around the two driving rollers, so that the grinding belt moves back and forth between the two driving rollers to grind the weld.

[0012] Preferably, a support rod is provided on the side of the spring sheet close to the guide rod, the support rod is arranged in a direction parallel to the weld, the guide rod is rotatably connected to the support rod, a slot is provided on the spring sheet, and a clamping strip cooperating with the slot is provided on the side of the grinding belt away from the weld.

[0013] The effect is that the guide rod drives the spring sheet 1 to move through the support rod, and when the spring sheet 1 abuts against the plate, the support rod rotates relative to the guide rod so that the spring sheet 1 abuts against the plate at different angles. At the same time, a groove is provided on the spring sheet 1 to cooperate with the clamping strip on the grinding belt. When the grinding belt is grinding the weld, the deviation or separation of the grinding belt relative to the spring sheet 1 is reduced, so that the grinding belt can move stably between the spring sheet 1 and the weld, thereby improving the effect of grinding the weld.

[0015] The effect is that the mounting frame is moved close to the weld, the spring piece 2 abuts against the plates on both sides of the weld, so that the brush 1 on the spring piece 2 abuts against the weld and the plates, and when the grinding belt moves up and down to grind the weld, the residue on the weld is cleaned by the brush 1.

[0016] Preferably, a brush 2 is provided on one side of the spring sheet 2 close to the weld, and one end of the brush 2 facing away from the spring sheet 2 is inclined in the direction of the grinding belt, and the end of the brush 2 abuts against the grinding belt to scrape off the residual welding slag on the grinding belt.

[0017] The effect is that when the grinding belt is grinding, the second brush and the grinding belt are kept in contact with each other, so that the grinding belt is cleaned and the impurities remaining on the grinding belt are reduced to affect the grinding.

[0018] Preferably, a control component is provided on the second elastic piece. The control component includes a mounting block, a roller, and a push rod. The mounting block is arranged on the second elastic piece. A middle rod is coaxially arranged on the roller. Both the middle rod and the push rod are slidably assembled on the mounting block up and down. The middle rod abuts against the bottom of the push rod. The upper end of the push rod abuts against one side of the second brush close to the grinding belt. An installation groove is formed on the mounting block. The roller is arranged in the installation groove. The side surface of the roller extends to the outside of the installation groove and abuts against the grinding belt.

[0019] The effect is that when the grinding belt moves in the direction towards the second brush in the direction from the grinding belt to the mounting block, the roller is driven to move upward synchronously. The roller drives the push rod to move upward through the middle rod. The push rod drives the inclined side of the second brush to retract, so that the inclined side of the second brush is separated from the grinding belt. At this time, the grinding belt is not cleaned. When the grinding belt moves in the reverse direction, the second brush contacts the grinding belt, and the impurities are cleaned to the outside of the grinding area, reducing the phenomenon that the impurities affect the grinding due to entering the grinding area.

[0020] Preferably, multiple groups of control components are arranged along the length direction of the second elastic piece. A connecting rope is arranged at one end of the push rod close to the second brush. The connecting rope is connected to the push rods in multiple groups of control components at the same time.

[0021] The effect is that when the push rod moves, it drives the connecting rope to move synchronously, thereby adjusting the inclination angles of various parts on the second brush at the same time.

[0022] Preferably, the side surface of the roller abuts against the inner wall of the installation groove, and the roller is rotationally matched with the middle rod.

[0023] The effect is that when the grinding belt moves up and down, it drives the roller to rotate. The roller moves up and down with the grinding belt under the action of the inner wall of the installation groove, thereby adjusting the positions of the middle rod and the push rod.

[0024] Preferably, an inclined groove is formed on the inner wall of the installation groove. The side of the inclined groove away from the other second elastic piece is inclined in the direction towards the grinding belt. The middle rod is slidably assembled in the inclined groove. A guiding surface is arranged on the inner wall of the installation groove. The guiding surface has the same inclination direction as the inclined groove. The side surface of the roller abuts against the guiding surface.

[0025] The effect is that when the grinding belt drives the roller to move, and the roller retracts the second brush through the middle rod and the push rod, the part of the side surface of the roller extending to the outside of the installation groove gradually increases, and at the same time, the corresponding part of the grinding belt is pushed away from the second elastic piece, so as to realize the separation of the grinding belt and the second brush.

[0026] Beneficial effects: In the present invention, by arranging a plurality of guide rods connected to the first elastic piece, the synchronous movement of the plurality of guide rods drives the first elastic piece to abut against the plates on both sides of the weld seam. At the same time, the first elastic piece deforms, clamping the grinding belt between the first elastic piece and the weld seam, so as to make the grinding belt closely adhere to the weld seam at the inner corner or the outer corner, so as to grind the weld seams at different positions and improve the grinding efficiency.

[0038] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but should not be construed as a limitation to the present invention.

[0039] As Figures 1 to 10 shown, the grinding device for barbecue grill production of the present invention includes a frame 2 placed on one side of the equipment body 1. An installation frame 3, a grinding assembly 4, a driving assembly 5, a guiding assembly 6, an auxiliary assembly 7, and a dust removal assembly 8 are provided on the frame 2. Movable wheels 21 are provided at the bottom of the frame 2 for moving the position of the frame 2. The installation frame 3 is slidably assembled up and down on the frame 2. A screw 22 is rotatably assembled on the frame 2. The screw 22 is in threaded engagement with the installation frame 3. A motor is provided on the frame 2, and the output end of the motor is coaxially connected to the screw 22. The driving assembly 5 cooperates with the grinding assembly 4 to control the grinding assembly 4 to grind the weld seam. At the same time, the guiding assembly 6 is used to control the grinding area to cover the weld seam, the auxiliary assembly 7 is used to clean the grinding assembly 4, and the dust removal assembly 8 is used to perform dust removal operations during grinding.

[0040] Referring to Figure 2 , Figure 3 , Figure 4 , the grinding assembly 4 includes a grinding belt 41. The driving assembly 5 includes: a driving member 51 and a driving roller 52. The driving member 51 is provided on the installation frame 3. The driving member 51 is set as a motor. The driving roller 52 is rotatably assembled on the installation frame 3. Two driving rollers 52 are arranged at intervals along the length direction of the weld seam. In this embodiment, the direction of the weld seam is the same as the moving direction of the installation frame 3, that is, the two driving rollers 52 are arranged at intervals in the vertical direction. The output end of the driving member 51 is coaxially connected to the driving roller 52 to drive the driving roller 52 to rotate. Both ends of the grinding belt 41 are respectively connected to the driving rollers 52.

[0041] The driving member 51 drives the driving roller 52 to rotate reciprocally, and at the same time drives the polishing belt 41 to alternately wind around the two driving rollers 52, so as to realize the reciprocating movement of the polishing belt 41 up and down in the polishing area to polish the weld seam.

[0042] Refer to Figure 3 、 Figure 4 、 Figure 5 , the guiding assembly 6 includes: a guiding frame 61, a hydraulic member 62, a guiding rod 63, and a first elastic piece 64. A sealing cavity 611 is formed in the guiding frame 61, and the sealing cavity 611 is filled with hydraulic oil. The hydraulic member 62 cooperates with the guiding frame 61, and the hydraulic member 62 is used to adjust the pressure of the hydraulic oil inside the guiding frame 61. The guiding rod 63 is slidably matched with the guiding frame 61, and one end of the guiding rod 63 extends into the guiding frame 61, and the other end is connected to the first elastic piece 64. The guiding rod 63 is slidably arranged in the direction towards the weld seam, and the first elastic piece 64 abuts against the side of the polishing belt 41 away from the weld seam. There are multiple guiding rods 63, and the multiple guiding rods 63 are arranged in the same plane, and the plane where the guiding rods 63 are located is perpendicular to the weld seam, and the multiple guiding rods 63 are simultaneously connected to the first elastic piece 64.

[0043] Before polishing, the hydraulic member 62 adjusts the oil pressure inside the guiding frame 61, and at the same time drives the guiding rod 63 to move in the direction towards the outside of the guiding frame 61, that is, the guiding rod 63 moves towards the weld seam. The movement of the guiding rod 63 drives the polishing belt 41 to approach the weld seam through the first elastic piece 64 until the polishing belt 41 abuts against the weld seam. At the same time, the guiding rod 63 continues to move, and the first elastic piece 64 deforms accordingly, driving the first elastic piece 64 to abut against the plates 11 on both sides of the weld seam. At the same time, the polishing belt 41 changes with the change of the first elastic piece 64, so that the polishing belt 41 is closely attached to the outside of the weld seam.

[0044] By simultaneously adjusting multiple guiding rods 63 before polishing, when polishing the internal angle weld seam and the external angle weld seam, the first elastic piece 64 can be driven to deform correspondingly, so that the polishing belt 41 abuts against the weld seam, improving the polishing effect on the weld seam.

[0045] Refer to Figure 3 、 Figure 4 、 Figure 5, the hydraulic component 62 includes: a cylinder 621, a push rod 622, a first pressing sleeve 623, and a second pressing sleeve 624. Both the first pressing sleeve 623 and the second pressing sleeve 624 are arranged inside the guiding frame 61. Both the first pressing sleeve 623 and the second pressing sleeve 624 communicate with the outside of the guiding frame 61. A push plate 625 is slidably assembled inside both the first pressing sleeve 623 and the second pressing sleeve 624. The push plate 625 is in sliding and sealing fit with the inside of the first pressing sleeve 623 and the second pressing sleeve 624. That is, when the push plate 625 moves inside the first pressing sleeve 623 or the second pressing sleeve 624, the pressure of the hydraulic oil inside the guiding frame 61 can be adjusted. The cylinder 621 is arranged outside the guiding frame 61. The output end of the cylinder 621 is connected to the push rod 622, and the push rod 622 is connected to the push plate 625 inside the first pressing sleeve 623. That is, when the cylinder 621 drives the push rod 622 to push the push plate 625 inside the first pressing sleeve 623 towards the inside of the guiding frame 61, the pressure of the hydraulic oil inside the guiding frame 61 can be increased. The guiding rod 63 is connected to the push plate 625 inside the second pressing sleeve 624.

[0046] There are multiple second pressing sleeves 624 corresponding to multiple guiding rods 63, and the second pressing sleeves 624 are arranged along the sliding direction of the guiding rods 63. That is, the second pressing sleeves 624 are sleeved outside the guiding rods 63.

[0047] When the position of the guiding rod 63 needs to be adjusted, the cylinder 621 drives the push rod 622 to move towards the inside of the guiding frame 61. The movement of the push rod 622 drives the push plate 625 inside the first pressing sleeve 623 to move and squeeze the hydraulic oil, increasing the pressure of the hydraulic oil inside the guiding frame 61. After the pressure inside the hydraulic oil increases, it drives the push plate 625 inside the second pressing sleeve 624 to move towards the outside of the guiding frame 61, thereby adjusting the position of the guiding rod 63.

[0048] Refer to Figure 5 , the inside of multiple second pressing sleeves 624 communicates with the inside of the guiding frame 61. After the pressure of the hydraulic oil inside the guiding frame 61 increases, it will be evenly distributed to the push plates 625 inside multiple second pressing sleeves 624. That is, when the guiding rod 63 drives the first elastic piece 64 to abut against the plate 11, the forces applied by multiple guiding rods 63 on the first elastic piece 64 are the same, so that the forces applied by the grinding belt 41 on each part of the weld are also the same, to improve the grinding quality of the weld. The first elastic piece 64 is arranged between two driving rollers 52 to reduce the phenomenon that the driving rollers 52 interfere with the movement of the first elastic piece 64.

[0049] Refer to Figure 5 、 Figure 6A support rod 641 is provided on one side of the spring sheet 1 64 close to the guide rod 63. The support rod 641 is provided in a direction parallel to the weld, that is, in this embodiment, the support rod 641 is provided in a vertical direction. There are multiple support rods 641, and the multiple support rods 641 are provided in a one-to-one correspondence with the multiple guide rods 63. The guide rod 63 is connected to the spring sheet 1 64 through the support rod 641. By providing the support rod 641, the spring sheet 1 64 is fitted with the plate 11, thereby improving the contact effect between the grinding belt 41 and the weld.

[0050] Reference Figure 5 , Figure 6 The guide rod 63 and the support rod 641 are rotatably matched, and the rotation axes of the guide rod 63 and the support rod 641 are arranged in the vertical direction. When the spring piece 64 abuts against the plate 11, the support rod 641 can rotate relative to the guide rod 63 to adapt to the grinding of welds at different angles.

[0051] In addition, a slot is provided on the spring piece 1 64, and a clip is provided on the side of the grinding belt 41 away from the weld, that is, the clip is provided on the side of the grinding belt 41 close to the spring piece 1 64, the clip is slidably matched with the slot, and the clip sleeve is clamped in the slot. This reduces the deviation of the grinding belt 41 and the spring piece 1 64, and prevents the grinding belt 41 from deviating relative to the weld during grinding, thereby improving the stability of the cooperation between the spring piece 1 64 and the grinding belt 41.

[0052] Reference Figure 2 , Figure 6 The auxiliary component 7 includes: a support plate 71 and a second spring piece 72. The support plate 71 is rotatably mounted on the mounting frame 3. The rotation axis of the support plate 71 is arranged parallel to the weld, that is, in this embodiment, the rotation axis of the support plate 71 is arranged along the vertical direction. There are two support plates 71, and the two support plates 71 are arranged on both sides of the grinding belt 41, and the support plate 71 is arranged on the side of the grinding belt 41 close to the weld. The two ends of the second spring piece 72 are respectively connected to the two support plates 71, and the second spring piece 72 is connected to the side of the support plate 71 away from the mounting frame 3. The length of the second spring piece 72 is greater than the distance between the rotation axis of the two support plates 71.

[0053] Reference Figure 6 There are two spring pieces 72 spaced apart at upper and lower intervals, the spring piece 1 64 corresponds to the middle of the spring piece 72, and a brush 721 is provided on one side of the spring piece 72 close to the weld.

[0054] During grinding, the movable mounting frame 3 is close to the weld, and the spring piece 2 72 is deformed, so that the brush 1 721 is closely attached to the weld and the plates 11 on both sides of the weld. When the mounting frame 3 moves up and down to drive the grinding belt 41 to grind the weld, the spring piece 2 72 cleans the residual impurities on the weld through the brush 1 721, thereby improving the treatment effect of the weld.

[0055] ReferenceFigure 2 , Figure 10 , because the length of the second elastic piece 72 is greater than the distance between the rotation axes of the two support plates 71. And in the initial state, the side of the support plate 71 close to the weld is inclined in the direction away from the other support plate 71, and the middle position of the second elastic piece 72 is deformed outward to be convex.

[0056] When it is necessary to grind the external corner weld, move the mounting frame 3 so that the middle part of the second elastic piece 72 abuts against the external corner weld. Then continue to move the mounting frame 3, and the second elastic piece 72 can be deformed, and its interior bends towards the mounting frame 3 until the two sides of the second elastic piece 72 abut against the external corner weld.

[0057] Refer to Figure 2 , Figure 10 , when it is necessary to grind the internal corner weld, move the mounting frame 3 so that the inclined support plate 71 abuts against the plates 11 on both sides of the weld. The mounting frame 3 continues to move closer to the weld, and the sides of the two support plates 71 close to the weld rotate towards each other. At the same time, the second elastic piece 72 is deformed, making the middle position of the second elastic piece 72 convex until the convex part of the second elastic piece 72 abuts against the internal corner weld, thereby assisting in grinding the internal corner weld.

[0058] Refer to Figure 7 , Figure 8 , Figure 9 , a second brush 722 is also provided on the side of the second elastic piece 72 close to the weld. Both the first brush 721 and the second brush 722 are vertical along the length direction of the second elastic piece 72. The end of the second brush 722 away from the second elastic piece 72 is inclined towards the grinding belt 41, and the inclined side of the second brush 722 abuts against the side surface of the grinding belt 41. When the grinding belt 41 grinds, the second brush 722 can clean the welding slag remaining on the grinding belt 41 to ensure the grinding effect of the grinding belt 41 on the weld.

[0059] A control assembly 9 is provided on the second elastic piece 72. The control assembly 9 includes: a mounting block 91, a roller 92, and a push rod 93. The mounting block 91 is provided on the second elastic piece 72 and connected to the second elastic piece 72. A middle rod 921 is coaxially provided on the roller 92. Both the middle rod 921 and the push rod 93 are slidably assembled up and down on the mounting block 91. The middle rod 921 abuts against the bottom of the push rod 93. The upper end of the push rod 93 abuts against the side of the second brush 722 close to the grinding belt 41. An installation groove 911 is opened on the mounting block 91. The roller 92 is arranged in the installation groove 911, and the side surface of the roller 92 extends outside the installation groove 911 to abut against the grinding belt 41.

[0060] Refer to Figure 7 , Figure 8 , Figure 9When the grinding belt 41 reciprocates, it drives the roller 92 to move accordingly. When the grinding belt 41 moves along the mounting block 91 towards the second brush 722, the grinding belt 41 drives the roller 92 to move. The roller 92 drives the ejector rod 93 to move closer to the second brush 722 through the intermediate rod 921, folding up the side of the second brush 722 close to the grinding belt 41, so that the second brush 722 is separated from the grinding belt 41. At this time, the second brush 722 does not clean the grinding belt 41. When the grinding belt 41 moves along the direction of the mounting block 91 towards the second brush 722, the roller 92 moves, and the ejector rod 93 moves away from the second brush 722 through the intermediate rod 921, so that the second brush 722 abuts against the grinding belt 41 again, cleaning the impurities on the surface of the grinding belt 41 and cleaning the impurities outside the grinding area, reducing the phenomenon that the impurities affect the grinding due to entering the grinding area.

[0061] Refer to Figure 7 、 Figure 8 、 Figure 9 The side of the roller 92 abuts against the inner wall of the mounting groove 911. When the grinding belt 41 moves, it drives the roller 92 to rotate. The rotation of the roller 92 can move along with the grinding belt 41 under the action of the inner wall of the mounting groove 911. At the same time, the roller 92 is rotationally matched with the intermediate rod 921. When the roller 92 moves along with the grinding belt 41, it rotates relative to the intermediate rod 921, so as to drive the intermediate rod 921 to move and adjust the positions of the intermediate rod 921 and the ejector rod 93.

[0062] Refer to Figure 7 、 Figure 8 、 Figure 9 The control assembly 9 is provided with multiple groups along the length direction of the second elastic piece 72. A connecting rope 931 is provided at one end of the ejector rod 93 close to the second brush 722. The connecting rope 931 is arranged along the length direction of the second brush 722. When the ejector rod 93 moves, it drives the connecting rope 931 to move. The connecting rope 931 drives the second brush 722 to fold up or unfold. By setting the connecting rope 931, the overall inclination angle of the second brush 722 can be adjusted.

[0063] Refer to Figure 7 、 Figure 8 、 Figure 9 An inclined groove 912 is formed on the inner wall of the mounting groove 911. The side of the inclined groove 912 away from the other second elastic piece 72 is inclined towards the grinding belt 41. The intermediate rod 921 is slidably assembled in the inclined groove 912 and slides along the length direction of the inclined groove 912. A guiding surface 913 is provided on the inner wall of the mounting groove 911. The roller 92 abuts against the guiding surface 913, that is, the roller rotates through the guiding surface 913 and moves synchronously with the grinding belt 41. The guiding surface 913 has the same inclination direction as the inclined groove 912.

[0064] When the roller 92 moves along with the grinding belt 41, the intermediate rod 921 moves within the inclined slot 912, causing the portion of the side of the roller 92 extending out of the mounting groove 911 to gradually increase. As a result, the grinding belt 41 is gradually pushed away from the second elastic piece 72, increasing the distance between the grinding belt 41 and the second elastic piece 72, so as to separate the grinding belt 41 from the second brush 722.

[0065] Refer to Figure 7 、 Figure 8 、 Figure 9 In the mounting block 91, a spring 914 is provided. The spring 914 is arranged along the sliding direction of the intermediate rod 921. One end of the spring 914 is connected to the mounting block 91, and the other end is connected to the intermediate rod 921. The spring 914 is used to drive the intermediate rod 921 to move in a direction away from the ejector rod 93. When the intermediate rod 921 moves, it will compress the spring 914. When the grinding belt 41 moves in the reverse direction, it is used to drive the roller 92 to move to the initial position.

[0066] Refer to Figure 2 、 Figure 3 On one side of the mounting frame 3 close to the weld, the dust removal assembly 8 includes: a dust removal box 81, an air pipe 82, and a suction plate 83. There are two sets of suction plates 83, and the two sets of suction plates 83 are respectively arranged on the upper and lower sides of the grinding belt 41. Every two suction plates 83 form a group, and the two suction plates 83 within each group are respectively close to the two mounting plates. The suction plate 83 is a hollow structure, and suction holes 831 are formed on the side of the suction plate 83 close to the grinding belt 41. The dust removal box 81 is arranged on the mounting frame 3, and both ends of the air pipe 82 are respectively communicated with the dust removal box 81 and the suction plate 83. A suction fan is arranged in the dust removal box 81. During grinding, air is pumped through the air pipe 82, so that the impurities generated during grinding sequentially enter the dust removal box 81 through the suction holes 831, the suction plate 83, and the air pipe 82, realizing the collection of impurities.

[0067] The implementation principle of the present invention is as follows: During grinding, the mounting frame 3 is moved, and the second elastic piece 72 is placed closely against the weld. Then, the hydraulic component 62 controls the pressure in the guiding frame 61 to increase, and the push plate 625 in the second pressing sleeve 624 drives a plurality of guiding rods 63 to move simultaneously. The guiding rods 63 drive the first elastic piece 64 to abut against the plates 11 on both sides of the weld, and at the same time drive the grinding belt 41 to closely adhere to the weld. By providing a plurality of guiding rods 63, the first elastic piece 64 can be driven to abut against the plates 11 on both sides of the inside corner weld or outside corner weld, so as to closely adhere the grinding belt 41 to the weld and grind the weld, improving the grinding efficiency of the weld.

[0068] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
