Abstract

The present invention relates to the technical field of metal grinding and processing, and specifically to a mobile house building matching structure grinding device, including a bracket plate, a clamping mechanism and a grinding mechanism. In the present invention, the grinding rollers of two grinding devices are closely attached to the two sides of the longitudinal square steel through the work of the centering group, and the longitudinal square steel is ground by the grinding device, thereby driving the two grinding rollers to evenly grind the welding position from bottom to top, avoiding the uneven adhesion of the anti-corrosion and anti-rust coating sprayed on the welding position due to the uneven metal surface around the connection position after the grinding process. After completing the grinding of the two end faces, the two grinding devices are driven by the rotating group to rotate ninety degrees around the center line of the square steel, and then the grinding equipment grinds the upper and lower end faces of the longitudinal square steel at the same time, which is easy to operate and saves labor costs and time costs.

Description

Technical Field

[0001] The invention relates to the technical field of metal grinding processing, in particular to a mobile house building matching structure grinding device. Background Art

[0002] Mobile homes are lightweight houses that use steel as their main structural material. They are easy to move, assemble and disassemble. The bottom plate of a mobile home is usually welded and assembled from horizontal and vertical square steel (see Figure 6 ), in order to extend the service life of the mobile house, the welding position needs to be polished and sprayed with anti-corrosion and anti-rust paint.

[0003] At present, the horizontal square steel and the longitudinal square steel welding position (see Figure 1 ) is usually ground by staff using grinding equipment (such as edge grinding machine) to grind the welding position.

[0004] The existing grinding of welding positions on the steel frame structure of mobile houses has the following problems: 1. In the existing grinding process of the steel frame structure of mobile houses, the staff uses handheld grinding equipment to grind the welding positions, which makes it difficult to achieve uniform and consistent grinding angles and strength at the connection positions, which can easily lead to uneven metal surfaces around the connection positions after grinding, resulting in uneven adhesion of the anti-corrosion and anti-rust coatings subsequently sprayed on the welding positions, thereby reducing the protective performance of the coatings at the welding positions of the steel frame structure of the mobile house, thereby shortening the service life of the mobile house.

[0005] 2. In the existing grinding process of the steel frame structure of the mobile house, the staff needs to use handheld grinding equipment to grind the four circumferential surfaces of the square steel at each welding position in turn, which consumes a lot of labor costs and time costs. The staff needs to repeat the same operation steps many times to grind the bottom plate of the mobile house, and the overall processing process is relatively cumbersome. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0032] like Figure 1 and Figure 2 As shown, a mobile house building matching structure grinding device comprises:

[0033] A bracket plate 1, wherein two symmetrically distributed sliding bars 2 are provided on the bracket plate 1 for sliding left and right, a movable plate 3 is fixedly provided on the lower end surface of the sliding bar 2, a clamping mechanism 4 is provided between the movable plate 3 and the bracket plate 1, an arc plate 5 is fixedly provided on the rear end surface of the bracket plate 1, an arc groove 50 extending along the shape of the arc plate 5 is provided on the rear end surface of the arc plate 5, a rotating bar 6 is provided in the arc groove 50 for sliding through a slider, a sliding plate 7 is provided on the rotating bar 6 for sliding up and down, the sliding plate 7 is driven to slide up and down by an external hydraulic cylinder (not shown in the figure), and a grinding mechanism 8 is provided between the sliding plate 7 and the arc plate 5.

[0034] The grinding mechanism 8 includes a vertical plate 80, and the rear end face of the sliding plate 7 is provided with two vertical plates 80 symmetrically distributed on the left and right sides for sliding. The rear end faces of the lower sections of the two vertical plates 80 are provided with grinding equipment 81, and the grinding equipment 81 includes a grinding roller for grinding the square steel connection area. A centering group 82 is commonly provided between the two vertical plates 80 and the sliding plate 7, and a rotating group 83 is commonly provided between the arc plate 5 and the rotating bar 6.

[0035] The clamping mechanism 4 includes a driving shaft 40, and the upper end surface of the bracket plate 1 is rotatably provided with a driving shaft 40 located between the two sliding bars 2 and with an axis extending from top to bottom. The driving shaft 40 is connected to an external motor 1 (not shown in the figure), and a driving group 41 is commonly provided between the driving shaft 40 and the bracket plate 1. A clamping group 1 42 is provided on each of the two movable plates 3. The rear end surface of the bracket plate 1 is fixedly provided with two stop bars 43 located on both sides of the arc plate 5 and symmetrically distributed on the left and right sides. The stop bars 43 are divided into a horizontal section, a vertical section and an inclined section from top to bottom, and the inclined section of the stop bar 43 is inclined upward from front to back. A guide group 44 is provided on the lower end surface of the bracket plate 1. The clamping mechanism 4 includes a clamping group 2 45 for limiting the front and rear positions of the bracket plate 1.

[0036] During work, the staff places the bracket plate 1 at the connection position between the horizontal square steel and the longitudinal square steel on the steel frame structure of the mobile house (see Figure 1), and the transverse square steel in the cross shape after welding is located between the clamping group 2 45 and the stop bar 43. During the downward placement process, the front and rear directions of the bracket plate 1 are initially limited by the cooperation between the clamping group 2 45 and the stop bar 43 and the transverse square steel. At the same time, the left and right directions of the bracket plate 1 are initially limited by the cooperation between the guide group 44 and the longitudinal square steel, and the guide group 44 supports the bracket plate 1. After that, the external motor 1 works through the driving shaft 40 to make the driving group 41 work. The driving group 41 drives the clamping group 1 42 to approach each other through the two moving plates 3 and clamp the longitudinal square steel. The positioning of the bracket plate 1 in the up and down and left and right directions is completed by clamping the longitudinal square steel, so that the axis of the arc plate 5 is in line with the center line of the longitudinal square steel. At the same time, the driving group 41 drives the clamping group 2 45 to work to complete the front and rear directions of the bracket plate 1 The upper limit is reached, and then the external hydraulic cylinder works to drive the two grinding devices 81 to move downward through the sliding plate 7. After the two grinding devices 81 move to the bottom of the longitudinal square steel, the centering group 82 works to drive the two grinding devices 81 to approach each other until they contact the left and right end faces of the longitudinal square steel. Then, the two grinding devices 81 work to grind the two end faces of the square steel through the grinding roller. At the same time, the external hydraulic cylinder works to drive the two grinding devices 81 to move upward synchronously through the sliding plate 7 until they are out of contact with the square steel, thereby completing the grinding of the two end faces of the longitudinal square steel. After the centering group 82 drives the grinding device 81 to reset, the rotating group 83 works to drive the two grinding devices 81 to rotate to the upper and lower sides of the longitudinal square steel respectively through the sliding plate 7. Then, the centering operation and grinding steps are repeated to complete the grinding of a connection position of the steel frame structure of the mobile house.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the guide group 44 includes a fixed plate 440, and four fixed plates 440 distributed in a matrix are fixedly set on the lower end surface of the bracket plate 1, and the two front and rear opposite fixed plates 440 are respectively located on the front and rear sides of the sliding bar 2, and a sliding rod 441 with an axis extending from left to right is slid through the fixed plate 440, and a guide plate 442 is fixedly set on the opposite surfaces of the two left and right opposite sliding rods 441. Taking the right guide plate 442 as an example, the guide plate 442 is divided into a horizontal section, a vertical section and an inclined section from top to bottom, and the inclined section of the guide plate 442 is inclined downward from left to right, and a spring 443 mounted on the corresponding sliding rod 441 is fixedly set between the guide plate 442 and the corresponding fixed plate 440.

[0038] During work, the staff places the bracket plate 1 above the longitudinal square steel that needs to be polished in the steel frame structure of the mobile house, and makes the longitudinal square steel be located between the two guide plates 442 opposite to each other on the left and right. During the downward placement process, the bracket plate 1 moves downward until the square steel contacts the inclined sections of the two guide plates 442, and the shape cooperation between the square steel and each guide plate 442 makes the two guide plates 442 opposite to each other move away from each other. The movement of the guide plate 442 causes the corresponding spring 443 to be compressed and deformed, and the initial limiting of the bracket plate 1 in the left and right directions is completed through the cooperation between the elastic forces generated by the deformation of the two springs 443 opposite to each other on the left and right. The bracket plate 1 continues to drive the fixed plate 440 to move downward until the horizontal section of the guide plate 442 contacts the upper end surface of the longitudinal square steel, and the bracket plate 1 stops moving downward. Through the shape cooperation between the horizontal section of each guide plate 442 and the longitudinal square steel, the support of the bracket plate 1 in the vertical direction is completed, and the bracket plate 1 is prevented from continuing to move downward, thereby completing the initial limiting of the bracket plate 1 in the vertical direction.

[0039] like Figure 2 and Figure 3 As shown, the driving group 41 includes a gear 1 410, a gear 1 410 is fixedly sleeved on the driving shaft 40, and a rack 1 411 meshing with the gear 1 410 is fixedly provided on the two sliding bars 2 through a connecting block, and the upper end surface of the bracket plate 1 is rotatably provided with two gear 2 413 located on both sides of the gear 1 410 and symmetrically distributed on the left and right sides through a rotating rod with a vertical axis, and the opposite back surfaces of the two sliding bars 2 are fixedly provided with rack 2 414 meshing with the corresponding gear 2 413, and the upper end surface of the bracket plate 1 is slidably provided with two rack 3 415 distributed symmetrically on the left and right sides and meshing with the corresponding gear 2 413, and the rack 2 414 and the corresponding rack 3 415 are staggered up and down.

[0040] During operation, after the bracket plate 1 is initially limited in the vertical direction by the guide group 44, the external motor 1 drives the gear 1 410 to rotate through the driving shaft 40, and the shape matching between the gear 1 410 and the two racks 1 411 makes the two racks 1 411 approach each other, and the two racks 1 411 respectively drive the two sliding bars 2 to approach each other, and the sliding bar 2 drives the corresponding clamping group 1 42 to move toward the middle through the moving plate 3 to limit the longitudinal square steel. At the same time, the two sliding bars 2 respectively drive the corresponding rack 2 414 to approach each other, and the corresponding gear 2 413 is rotated through the meshing between the rack 2 414 and the corresponding gear 2 413, and the corresponding rack 3 415 is moved forward through the meshing between the gear 2 413 and the rack 3 415. In the subsequent working process, the rack 3 415 drives the clamping group 2 45 to work to limit the front and rear directions of the bracket plate 1.

[0041] like Figure 2As shown, the rear end faces of the two rack threes 415 are each provided with a clamping group 2 45, and the clamping group 2 45 includes a pulling rod 450, and the rear end faces of the two rack threes 415 are each fixedly provided with a pulling rod 450 whose axis extends from front to rear, and the rear section of the pulling rod 450 is slidably sleeved with a pulling bar 451, and the pulling bar 451 is divided into a vertical section and an inclined section from top to bottom, and the inclined section of the pulling bar 451 is inclined downward from front to back, and the pulling rod 450 is fixedly provided with a spring 2 452 sleeved on the corresponding pulling rod 450 through a rectangular plate and the pulling bar 451.

[0042] During work, the staff places the bracket plate 1 above the longitudinal square steel that needs to be polished on the steel frame structure of the mobile house, and makes the transverse square steel located between the stop bar 43 and the corresponding pulling bar 451. After the bracket plate 1 moves downward until the inclined section of the pulling bar 451 contacts the square steel, the pulling bar 451 moves backward through the shape matching between the transverse square steel and the inclined section of the pulling bar 451. The movement of the pulling bar 451 causes the corresponding spring 2 452 to be compressed and deformed. After the bracket plate 1 continues to move downward until the transverse square steel contacts the vertical section of the stop bar 43 and the vertical section of the pulling bar 451, the elastic force generated by the deformation of the spring 2 452 acts on the bracket plate 1 through the corresponding pulling rod 450, thereby preliminarily limiting the position of the bracket plate 1 in the front-to-back direction.

[0043] After completing the preliminary limiting of the bracket plate 1 in the up and down directions and the front and back directions, the external motor 1 works to drive the two racks 3 415 to move forward through the driving group 41, and the racks 3 415 drive the corresponding pulling rods 450 to move forward. The movement of the pulling rods 450 causes the springs 2 452 to be continuously compressed and deformed. The elastic force generated by the compression and deformation of the springs 2 452 acts on the bracket plate 1 through the corresponding rotating rods. The bracket plate 1 is pulled backward by the two rotating rods until the vertical sections of the two stop bars 43 contact the front end surface of the horizontal square steel. The limiting of the bracket plate 1 in the front and back directions is completed, so that the grinding rollers of the grinding equipment 81 are located on both sides of the area to be polished. After that, the two racks 3 415 continue to drive the corresponding pulling rods 450 to move forward, and the springs 2 452 are continuously compressed and deformed. During the subsequent resetting process, the driving group 41 works to push the two pulling rods 450 to move backward until the pulling bar 451 moves to disengage from the horizontal square steel.

[0044] like Figure 2 and Figure 3As shown, the clamping group 42 includes a clamping plate 420, and the opposite surfaces of the two movable plates 3 are provided with two clamping plates 420 symmetrically distributed up and down through a movable bar that slides up and down, and a horizontal bar 421 that slides left and right on the movable plate 3 and passes through the two clamping plates 420 located on the same movable plate 3, and clamping plates 422 are fixedly provided on the opposite surfaces of the two horizontal bars 421, and a connecting bar 423 is hinged between each horizontal bar 421 and the corresponding two movable bars, and a spring 3 424 is fixedly provided between each movable bar and the corresponding movable plate 3.

[0045] During operation, the clamping group 1 42 limits the front and rear directions of the bracket plate 1, and the two sliding bars 2 approach each other and drive the corresponding moving plate 3 to move synchronously. The moving plate 3 drives the corresponding clamping plate 2 422 to move synchronously through the corresponding horizontal bar 421, until the clamping plate 2 422 on one side moves to contact the longitudinal square steel, the corresponding clamping plate 2 422 stops moving, and the moving plate 3 continues to move, so that the horizontal bar 421 pulls the corresponding connecting bar 423 to move, and the connecting bar 423 pulls the corresponding moving bar to move synchronously, and the two moving bars on the same moving plate 3 approach each other, and the movement of the moving bar causes the corresponding spring 3 424 to be compressed and deformed, and the moving bar drives the corresponding clamping plate 1 420 to move synchronously. Until the two clamping plates 420 are in contact with the upper and lower end surfaces of the longitudinal square steel, the clamping of one side of the longitudinal square steel is completed, and then the driving group 41 continues to work to drive the two movable plates 3 closer to each other until the clamping group 42 completes the positioning clamping of the longitudinal square steel. Through the cooperation between the clamping group 42 and the longitudinal square steel, the position of the support plate 1 in the up and down and left and right directions is limited, and the arc plate 5 is driven to move synchronously through the support plate 1, so that the axis of the arc plate 5 moves to be colinear with the center line of the square steel. In the subsequent resetting process, the elastic force generated by the deformation of the spring three 424 acts on the corresponding moving bar, so that the two moving bars opposite to each other drive the corresponding clamping plates 420 away from each other.

[0046] like Figure 2 and Figure 4 As shown, the centering group 82 includes a rotating shaft 820, and the rear end face of the sliding plate 7 is rotatably provided with a rotating shaft 820 whose axis extends from front to rear, and the rotating shaft 820 is connected to an external motor 2 (not shown in the figure), and a gear 3 821 is fixedly sleeved on the rotating shaft 820, and racks 4 822 meshing with gear 3 821 are provided on the opposite surfaces of the two vertical plates 80.

[0047] In the initial state, the rotating bar 6 is in a vertical state. When working, after completing the limiting of the bracket plate 1 and the arc plate 5, the external motor 2 works to drive the gear 3 821 to rotate through the rotating shaft 820, and the two racks 4 822 are meshed with each other, so that the two racks 4 822 are close to each other, and the two racks 4 822 respectively drive the corresponding vertical plates 80 to move synchronously, until the two vertical plates 80 drive the grinding rollers on the corresponding grinding devices 81 to move close to the two sides of the longitudinal square steel, so that the subsequent grinding rollers can grind the two sides of the longitudinal square steel more evenly. The two grinding devices 81 work to drive the grinding rollers to grind the longitudinal square steel, and the external hydraulic cylinder works to make the sliding plate 7 move downward along the rotating bar 6, and the sliding plate 7 drives the two vertical plates 80 to move downward synchronously. When it reaches the lowest end of the rotating bar 6, the vertical plate 80 drives the corresponding grinding device 81 to move downward to complete the grinding and polishing of the left and right end faces of the longitudinal square steel. After the external motor 2 works to drive the centering group 82 to reset, the external hydraulic cylinder works to drive the two grinding devices 81 to move upward through the sliding plate 7. After the sliding plate 7 and the centering group 82 are reset, the rotating group 83 works to drive the sliding plate 7 to rotate around the axis of the arc plate 5 to a horizontal state through the rotating bar 6. Then the centering group 82 repeats the centering movement and mobile grinding until the grinding process of a connection point is completed. After completing the grinding of the two end faces at the welding position of the square steel, the two grinding devices 81 are driven to rotate synchronously by ninety degrees through the rotating group 83, and then the upper and lower end faces of the square steel are ground, saving labor costs and time costs.

[0048] like Figure 2 , Figure 4 and Figure 5 As shown, the rotating group 83 includes a transmission shaft 830, and the front end surface of the rotating bar 6 is rotatably provided with a transmission shaft 830 with two axes extending from top to bottom through a fixed block, and the transmission shaft 830 is connected to an external motor three (not shown in the figure), and the two transmission shafts 830 are respectively located on the upper and lower sides of the arc plate 5, and gear four 831 is fixedly provided on the opposite surfaces of the two transmission shafts 830, and the inner and outer annular surfaces of the arc plate 5 are fixedly provided with an arc-shaped rack plate 832 that meshes with the corresponding gear four 831.

[0049] like Figure 4 and Figure 5As shown, a locking group 84 is commonly provided between the arc groove 50 and the arc plate 5, and the locking group 84 includes a placement groove 840. Two placement grooves 840 are provided on the arc plate 5, which are respectively located at the head and tail sides of the arc groove 50. A rotating plate 841 is rotatably provided in the placement groove 840 through a fixed rod, and the rear end face of the rotating plate 841 is located above the sliding plate 7. A spring four 842 is commonly fixedly provided between the rotating plate 841 and the inner wall of the placement groove 840, and a locking block 843 is fixedly provided on the upper end face of the rotating plate 841. The locking block 843 is a right-angled trapezoid, and the inclined surface faces the right side, and the inclined surface is inclined downward from left to right.

[0050] In the initial state, the rotating bar 6 is in a vertical state, and the left end face of the locking block 843 in the upper locking group 84 contacts the right end face of the slider. During operation, after the centering group 82 completes the reset, the external hydraulic cylinder drives the sliding plate 7 to move upward. After the sliding plate 7 moves to the upper end face and contacts the rotating plate 841, the sliding plate 7 continues to move upward to push the rotating plate 841. The rotating plate 841 drives the corresponding locking block 843 to move downward until the locking block 843 and the slider are staggered and the spring four 842 is compressed and deformed.

[0051] After the locking block 843 moves to the point where the slider is out of contact, the external motor three works to drive the corresponding gear four 831 to rotate through the transmission shaft 830. Through the meshing between the gear four 831 and the corresponding rack plate 832, the gear four 831 drives the rotating bar 6 to rotate through the transmission shaft 830. The rotating bar 6 drives the centering group 82 and the two vertical plates 80 to rotate synchronously through the sliding plate 7. During the rotation process, the external hydraulic cylinder continues to work to drive the sliding plate 7 to move to a section of the rotating bar 6 away from the longitudinal square steel. After the sliding plate 7 moves to the point where it is out of contact with the upper rotating plate 841, the rotating plate 841 pushes the locking block 843 to move upward and reset under the action of the elastic force generated by the deformation of the spring four 842. After the slider moves to contact with the lower locking block 843, the shape cooperation between the slider and the corresponding inclined surface of the locking block 843 makes the slider push the locking block 843 to push the locking block 843 to move left, and the locking block 843 moves The corresponding rotating plate 841 is driven to rotate, so that the corresponding spring four 842 is compressed and deformed. After the slider moves to disengage from the locking block 843, the elastic force generated by the deformation of the spring four 842 pushes the locking block 843 to move right and reset through the rotating plate 841, and the lower end surface of the lower locking block 843 is used to prevent the slider from moving along the arc groove 50, so that the rotating bar 6 is in a horizontal state. Then the centering group 82 repeats the centering movement and mobile grinding until the grinding process of the welding position of the longitudinal square steel and the transverse square steel on one side is completed. Then the staff removes the bracket plate 1 and places it on the longitudinal square steel on the rear side, and repeats the above-mentioned positioning clamping, centering of the grinding equipment and grinding after rotation. The grinding process of a transverse square steel and the connection position of two longitudinal square steels in the middle position of the mobile house steel frame structure is divided into two grinding processes at the connection position of a transverse square steel and a longitudinal square steel.
