Description

Technical Field

[0001] The present invention relates to the technical field of metal rim welding equipment, in particular to a metal rim steel plate welding device and method with a multi-point fixing structure. Background Art

[0002] The rim, commonly known as the wheel rim, is the component on the wheel that mounts and supports the tire. It forms a wheel with the spokes. The rim and spokes can be integral, permanently connected, or detachable. There are two common types of rims: deep groove rims and flat bottom rims. In addition, there are split rims, semi-deep groove rims, deep groove wide rims, flat bottom wide rims, and full bevel bottom rims.

[0003] Before welding the rim, the rim needs to be clamped and fixed to facilitate more stable welding of the rim later. However, the rim needs to be constantly adjusted during the welding process after clamping to facilitate welding at different angles of the rim. A large amount of debris is generated during the welding process. The debris is thrown out to the vicinity of the welding work area when the rim is constantly adjusted. Long-term accumulation will affect the subsequent adjustment of the direction of the rim and the staff needs to clean it up, thereby affecting the efficiency of the subsequent welding work. In addition, the rim generates a large amount of heat during the existing rim welding process, and the staff needs to send the rims to a dedicated cooling equipment for cooling before they can be put into use, thereby affecting production efficiency. In view of this, we propose a metal rim steel plate welding device and method with a multi-point fixing structure. Summary of the Invention

[0004] The object of the present invention is to provide a metal rim steel plate welding device and method with a multi-point fixing structure to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, one of the purposes of the present invention is to provide a metal rim steel plate welding device with a multi-point fixing structure, comprising a workbench, a control panel fixedly connected to the surface of the workbench, a welding structure for welding the rim provided on the top of the workbench, a receiving and collecting structure provided on the top of the workbench, the receiving and collecting structure including at least a collection box, a multi-directional clamping structure provided on the top of the receiving and collecting structure, the multi-directional clamping structure including at least a clamping plate;

[0006] The receiving and collecting structures are moved away from each other and the debris collection range of the collection box is increased, and then the welding structure is driven to weld the rim. At the same time, the multi-directional clamping structures are driven away from each other and the multiple clamping plates are driven to gather inward to clamp the rim in multiple directions, and the welding process of the welding structure is cooled by blowing air.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] 1. The staff places the rim on the surface of the receiving and collecting structure to place it firmly. Then, when the rim needs to be clamped in multiple directions, the receiving and collecting structures are started to move away from each other to loosen the firmly placed rim, and the collection boxes are driven away from each other to increase the collection range of the debris generated by the rim welding. On the one hand, this is to ensure that the rim can be placed firmly on the receiving and collecting structure to reduce the offset phenomenon during the subsequent multi-directional clamping. On the other hand, when the direction is adjusted later, the debris generated by the welding will splash near the welding work area, thereby affecting the work efficiency of the subsequent welding.

[0009] 2. When the size of the collection box is adjusted by moving the receiving and collecting structures away from each other, the multi-directional clamping structures can be driven to move away from each other, and multiple clamping plates can be driven to gather inward to clamp the rim in multiple directions for stability, which is convenient for subsequent welding of the rim. The high temperature generated during welding can also be cooled by blowing air. On the one hand, it is convenient for subsequent adjustment of the rim angle and increase the welding speed of the subsequent welding structure to the rim. On the other hand, it is to increase the cooling speed of the welded rim, thereby promoting the phase change of the rim and forming a denser organizational structure, which is beneficial to improve the hardness and strength of the weld and enhance the mechanical properties of the weld.

[0010] Preferably, the receiving and collecting structure comprises at least a receiving plate, the receiving plate being fixedly connected to the top surface of the workbench, a triangular guide plate for guiding debris being provided inside the receiving plate, guide ports being provided on both sides of the receiving plate, and an arc-shaped device being provided on the top of the receiving plate;

[0011] By further adopting the above technical solution, when in use, the receiving plate is arranged in an arc shape, so that the rim can be better placed, thereby improving subsequent rim welding or processing.

[0012] Preferably, the welding structure includes a first motor, which is fixedly connected to the inner cavity of the workbench, and the output end of the first motor is fixedly connected to a first screw rod, and the end of the first screw rod away from the first motor is rotatably connected to the inner cavity of the workbench, and the outer ring surface of the first screw rod is threadedly connected to a welding device, and the welding device is divided into a welding head and a threaded plate.

[0013] Further adopting the above technical solution can better move the welding equipment to align with the rim, thereby improving work efficiency.

[0014] Preferably, the receiving and collecting structure further comprises at least a second motor, the second motor is fixedly connected to the top of the workbench, the output end of the second motor is fixedly connected to a second screw rod, the outer ring surface of the second screw rod is threadedly connected to a threaded block, the top of the threaded block is fixedly connected to a sliding plate, the side of the sliding plate is rotatably connected to the first swing plate, the side of the first swing plate away from the sliding plate is rotatably connected to a collection box, the collection box and the receiving plate are slidably connected, and the receiving and collecting structure is symmetrically arranged in two groups along the transverse center of the workbench;

[0015] Further adopting the above technical solution can increase the range of the rim when mobile phone debris is detected, and also facilitate the subsequent multi-directional clamping structure to clamp the rim in multiple directions.

[0016] Preferably, the multi-directional clamping structure at least includes a triangular fixed plate, the side surface of the triangular fixed plate is fixedly connected to the third motor, the triangular fixed plate is rotatably connected to the rotating disk on the side of the triangular fixed plate away from the third motor, and the rotating disk is rotatably connected to four second swing plates on the side away from the third motor, and the four second swing plates are respectively rotatably connected to the four clamping plates on the side away from the rotating disk, the four clamping plates are fixedly connected to four limit plates on the inner sides of the four clamping plates, and the four limit plates are respectively slidably connected to the fixed plate on the side away from the clamping plate, and the fixed plate is provided with a sliding groove that adapts to the limit plate, and four fans are respectively installed on the surfaces of the four limit plates, and the fixed plate is slidably connected to a sliding post inside the fixed plate, and one end of the sliding post away from the fixed plate is fixedly connected to the side surface of the rotating disk;

[0017] By further adopting the above technical solution, the rim can be clamped in multiple directions and the rim can be adjusted to facilitate subsequent welding of the rim.

[0018] Preferably, the two sides of the first swing plate are rotatably connected to the sliding plate and the side of the collection box through pins respectively. The swing distance of the first swing plate can increase the maximum range of the collection box. Two sets of rectangular sliding grooves are provided on the surface of the sliding plate, and are used to adjust the distance of the multi-directional clamping structure. The weight borne by the sliding plate is sufficient to bear the weight of the entire structure of the multi-directional clamping structure.

[0019] Preferably, the four clamping plates are respectively arranged in an arc shape and are adapted to the arc-shaped edge of the rim. The limiting plates fixed on the inner sides of the four clamping plates have the same sliding distance as the inner cavity of the fixed plate.

[0020] Preferably, when the two sliding plates are in a state of moving away from each other, the first swinging plate connected by rotation on the side of the sliding plate is in a vertical state, and the first swinging plate is connected by rotation away from one side of the sliding plate so that the two collection boxes are in a state of maximum distance from each other; when the two sliding plates are in a state of approaching each other, the first swinging plate connected by rotation on the side of the sliding plate is in a swinging state, and the first swinging plate is connected by rotation away from one side of the sliding plate so that the two collection boxes are in a state of maximum distance from each other.

[0025] Step 3: When the two sliding plates move away from each other, the four clamping plates will be brought together to clamp the rim placed on the receiving plate, making it easier to adjust the angle of the rim later;

[0026] Step 4: Start the third motor to rotate and adjust the rim clamped in multiple directions by the four clamping plates, so that the welding structure welds the rim being adjusted, thereby completing the multi-directional clamping and welding of the rim. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] For example 1 of the present invention, please refer to Figures 1-9 A metal rim steel plate welding device and method with a multi-point fixing structure includes a workbench 1, a control panel 2 is fixedly connected to the surface of the workbench 1, a welding structure 3 for welding the rim is provided on the top of the workbench 1, a receiving and collecting structure 4 is provided on the top of the workbench 1, and the receiving and collecting structure 4 includes at least a collection box 43, and a multi-directional clamping structure 5 is provided on the top of the receiving and collecting structure 4, and the multi-directional clamping structure 5 includes at least a clamping plate 55;

[0040] By supporting the collecting structures 4 to move away from each other and increase the debris collection range of the collection box 43, the welding structure 3 is driven to weld the rim. At the same time, the multi-directional clamping structures 5 can be driven to move away from each other and drive multiple clamping plates 55 to gather inward to clamp the rim in multiple directions, and the welding process of the welding structure 3 can be cooled by blowing air.

[0041] First of all, why do we need to weld the rims? This is because welding is an important connection method in automobile manufacturing, used to firmly connect different parts together. For metal rims, the firmness of welding is particularly important because it is directly related to the load-bearing capacity and driving safety of the wheel. Therefore, welding the rims is necessary to improve vehicle safety and stability.

[0042] Next, considering that debris is generated during the welding process, when the rim angle is adjusted in the existing method, the debris generated by the welding on the rim surface will fall near the rim welding. If the fallen debris is not cleaned up in time at the bottom of the rim, it may rub against the rim surface during the subsequent rim rotation and angle adjustment process, causing rim surface wear. The rim surface wear will reduce the strength and corrosion resistance of the rim, and may also affect the matching accuracy between the rim and the tire, resulting in loose tire installation or air leakage. Therefore, by moving the receiving and collecting structures 4 away from each other, the firmly placed rims are loosened, and the collection boxes 43 are driven away from each other, so that the collection range of the debris generated by the rim welding is increased. In addition, since the receiving and collecting structure 4 placed under the rim can collect the debris generated by the rim welding, it can not only collect the debris generated by the rim welding and reduce the friction between the rim and the rim surface when the rim is rotated to adjust the angle, but also increase the collection range of the collection box 43, thereby improving production efficiency.

[0043] Moreover, considering that a large amount of high temperature is generated during the existing welding process, the rims need to be collectively sent to a dedicated cooling device for cooling by the staff before they can be put into use. This not only increases the complexity of the work, but also affects production efficiency and over-reliance on dedicated cooling equipment. If the cooling equipment fails or requires maintenance, the entire cooling process will be seriously affected, and even lead to production stagnation. The company needs to invest additional resources to ensure the stable operation of the cooling equipment. Therefore, the multi-directional clamping structure 5 is moved away from each other and drives the multiple clamping plates 55 to gather inward to clamp the rim in multiple directions, which is convenient for subsequent welding of the rim. The multi-directional clamping structure 5 can also be used to blow air to dissipate the heat generated during welding, thereby facilitating the subsequent adjustment of the rim angle, increasing the welding speed of the subsequent welding structure 3 on the rim, and accelerating the cooling speed of the welded rim, thereby improving the mechanical properties of the weld.

[0044] The following is a specific structure to achieve the above-mentioned problems:

[0045] Here is the working principle of the control panel 2, which is convenient for understanding the following text. When the control panel 2 is operated by the staff to control other components, the other components will receive the input of production instructions and process parameters and upload the production process and results in real time to achieve intelligent control. For example, when the staff controls the receiving and collecting structure 4 on the control panel 2, the starting device in the receiving and collecting structure 4 detects the signal controlled by the control panel 2 and executes the operation of the receiving and collecting structure 4. This control logic can be implemented by a hard-wired logic circuit or by software programming in a microprocessor, thereby facilitating the control of the starting devices of subsequent components and reducing the complexity of the rim welding process (the specific working process will not be elaborated in detail when the control panel 2 controls other components below).

[0046] First, to place the rim and facilitate subsequent welding of the rim, the receiving and collecting structure 4 needs to be disclosed in detail. Please refer to Figure 2-Figure 4 The receiving and collecting structure 4 at least includes a receiving plate 44, which is fixedly connected to the top surface of the workbench 1. A triangular guide plate 441 for diverting debris is provided inside the receiving plate 44, and guide ports 442 are provided on both sides of the receiving plate 44. The top of the receiving plate 44 is an arc-shaped device. When the rim needs to be welded, the staff needs to place the rim on the top of the receiving plate 44 to facilitate the subsequent welding structure 3 to weld the rim, and the triangular guide plate 441 and the guide port 442 can also be used to divert and collect the debris generated by the subsequent welding.

[0047] Next, to realize the welding of the rim, the specific structure of welding structure 3 needs to be disclosed, please refer to Figure 1-Figure 2 The welding structure 3 includes a first motor 33, which is fixedly connected to the inner cavity of the workbench 1. The output end of the first motor 33 is fixedly connected to the first screw rod 32. The end of the first screw rod 32 away from the first motor 33 is rotatably connected to the inner cavity of the workbench 1. The outer ring surface of the first screw rod 32 is threadedly connected to the welding device 31. The welding device 31 is divided into a welding head and a threaded plate. When the rim is placed on the receiving plate 44, the staff operates the control panel 2 to start the first motor 33, and then drives the first screw rod 32 to rotate forward or reverse, so that the threaded plate in the welding device 31 threadedly connected to the first screw rod 32 moves on the surface of the first screw rod 32 until the welding head on the welding device 31 is aligned with the rim placed on the receiving plate 44, and welding is performed, thereby completing the welding of the rim.

[0048] The working principle and specific reasons of the first screw rod 32 and the threaded plate in the welding device 31 will be explained here. When the first screw rod 32 rotates, due to the presence of the thread, a force along the spiral direction of the thread will be generated on the threaded plate of the welding device 31. This force can be decomposed into two components, one is the force that causes the threaded plate of the welding device 31 to rotate around the axis of the first screw rod 32, and the other is the force that causes the threaded plate of the welding device 31 to move axially along the first screw rod 32. Under normal circumstances, the threaded plate of the welding device 31 will be restricted by other structures, so that its rotational movement around the axis of the first screw rod 32 is constrained and it can only move along the axial direction of the first screw rod 32. Therefore, the rotational movement of the first screw rod 32 is converted into a linear movement of the threaded plate of the welding device 31 through the transmission of the force of the thread, thereby completing the adjustment of the threaded plate and the welding head of the welding device 31 until it is aligned with the rim where the receiving plate 44 is placed, reducing manual alignment and reducing errors.

[0049] In order to improve the collection range of debris generated during welding, the specific structure of the receiving and collecting structure 4 needs to be disclosed in detail. Please refer to Figure 2-Figure 4 The receiving and collecting structure 4 at least further includes a second motor 46, which is fixedly connected to the top of the workbench 1. The output end of the second motor 46 is fixedly connected to a second screw rod 45, and the outer ring surface of the second screw rod 45 is threadedly connected to a threaded block 47. The top of the threaded block 47 is fixedly connected to a sliding plate 41. The side of the sliding plate 41 is rotatably connected to a first swing plate 42. The side of the first swing plate 42 away from the sliding plate 41 is rotatably connected to a collecting box 43. The collecting box 43 is slidably connected to the receiving plate 44. The receiving and collecting structure 4 is symmetrically arranged in two groups along the transverse center of the workbench 1.

[0050] The two sides of the first swing plate 42 are rotatably connected to the sliding plate 41 and the side of the collection box 43 through pins. The swing distance of the first swing plate 42 can increase the maximum range of the collection box 43. The surface of the sliding plate 41 is provided with two sets of rectangular sliding grooves 411, which are used to adjust the distance of the multi-directional clamping structure 5. The weight borne by the sliding plate 41 is sufficient to bear the weight of the entire structure of the multi-directional clamping structure 5.

[0051] When the two sliding plates 41 are in a state of moving away from each other, the first swinging plate 42 connected by the side rotation of the sliding plate 41 is in a vertical state, and the first swinging plate 42 is away from the side of the sliding plate 41 and the two collecting boxes 43 are in a state of maximum distance from each other. When the two sliding plates 41 are close to each other, the first swinging plate 42 connected by the side rotation of the sliding plate 41 is in a swinging state, and the first swinging plate 42 is away from the side of the sliding plate 41 and the two collecting boxes 43 are in a state of maximum distance from each other. During the rim welding process, debris will be generated because the welding rod or welding wire may be mixed with some impurities during the production process, such as metal oxides, silicates, etc. During welding, these impurities cannot be well integrated with the base material and will form debris falling off under high temperature. For example, when the oxygen content in the welding wire is high, more debris such as oxide scale will be generated during the rim welding process. Therefore, the two second motors 46 are started through the work control panel 2 to make the two second screw rods 45 rotate, and then the two threaded blocks 47 will be respectively in the two second The screw rod 45 moves on the surface (the working principle here is the same as the working principle of the welding equipment 31 and the first screw rod 32 mentioned above), and then drives the two sliding plates 41 to move away from each other, and drives each first swinging plate 42 from the swinging state to the vertical state, and in the process of becoming vertical, each drives the two collection boxes 43 to move away from each other. This is because the collection box 43 connected to the side of the first swinging plate 42 away from the sliding plate 41 is provided with a linear slide groove on the surface of the workbench 1. Therefore, when moving away from the collection box 43, the collection box 43 will pull the first swinging plate 42, so that the collection box 43 on the side of the first swinging plate 42 away from the sliding plate 41 slides in the linear slide groove provided on the surface of the workbench 1, so that the first swinging plate 42 changes from the swinging state to the vertical state, thereby causing the two collection boxes 43 to slide on the outer ring surface of the receiving plate 44, thereby increasing the collection range of the collection box 43, making it convenient for the subsequent wheel rim to adjust the angle of the fallen debris, and reducing the work process of cleaning the inner cavity of the collection box 43.

[0052] Next, in order to facilitate the angle adjustment of the rim, the specific structure of the multi-directional clamping structure 5 needs to be disclosed in detail, please refer to Figure 6-Figure 9The multi-directional clamping structure 5 at least includes a triangular fixed plate 51, a third motor 52 is fixedly connected to the side of the triangular fixed plate 51, a rotating disk 53 is rotatably connected to the side of the triangular fixed plate 51 away from the third motor 52, and four second swinging plates 54 are rotatably connected to the side of the rotating disk 53 away from the third motor 52. The four second swinging plates 54 are respectively rotatably connected to four clamping plates 55 on the side away from the rotating disk 53. Four limiting plates 56 are fixedly connected to the inner sides of the four clamping plates 55. The four limiting plates 56 are respectively slidably connected to a fixed disk 57 on the side away from the clamping plates 55. A sliding groove that adapts to the limiting plate 56 is opened inside the fixed disk 57. Four fans 59 are respectively installed on the surface of the four limiting plates 56. A sliding column 58 is slidably connected to the inside of the fixed disk 57. One end of the sliding column 58 away from the fixed disk 57 is fixedly connected to the side of the rotating disk 53.

[0053] The four clamping plates 55 are each arc-shaped and fit in with the arc-shaped edge of the rim. The limiting plates 56 fixed on the inner sides of the four clamping plates 55 have the same sliding distance as the inner cavity of the fixing plate 57. The air blown by four fans 59 installed on the surface of the four limiting plates 56 can dissipate heat from the rim.

[0054] When the four clamping plates 55 are in a state of being away from each other, the bottoms of the four clamping plates 55 are rotated to connect the four second swinging plates 54 in a swinging state, and the limiting plates 56 fixed on the side of the clamping plates 55 away from the second swinging plates 54 are in a state of not sliding inside the fixed plate 57. When the four clamping plates 55 are in a state of being close to each other, the bottoms of the four clamping plates 55 are rotated to connect the four second swinging plates 54 in a vertical state, and the limiting plates 56 fixed on the side of the clamping plates 55 away from the second swinging plates 54 are in a state of sliding the maximum distance inside the fixed plate 57. When the size of the collecting box 43 is adjusted by moving the sliding plate 41, the movement of the sliding plate 41 will drive the triangular fixed plate 51 to move, and then drive the multi-directional clamping structure 5 as a whole to move away from each other. At this time, since the sides of the fixed plate 57 are respectively engaged with the sides of the rim, when the two triangular fixed plates 51 move away from each other, they will synchronously drive the rotating plate 53 to move, and then the movement of the rotating plate 53 will drive the sliding post 58 to slide inside the fixed plate 57, so that the side of the rotating plate 53 rotates and the second swing plate 54 connected to the four sides changes from a swinging state to a slightly swinging state (please refer to the embodiment for details). Figure 9 ), then the four second swinging plates 54 will drive the four clamping plates 55 to gather inward during the swinging process, and will simultaneously drive the four limit plates 56 to slide inside the fixed plate 57, so that the fans 59 installed on the surfaces of the limit plates 56 are aligned with the rims, and the four clamping plates 55 will clamp the rims placed on the receiving plates 44 in multiple directions, making it easier to adjust the angle of the rims later;

[0055] When the four clamping plates 55 clamp the rim in multiple directions, the staff starts the third motor 52 to rotate the third motor 52 fixedly connected to the output end, which then drives the four second swing plates 54 to rotate, and synchronously drives the rim clamped in multiple directions by the four clamping plates 55 to rotate. When the four clamping plates 55 adjust the angle of the clamped rim, the staff can also control the control panel 2 to start each fan 59, so that the wind blown by the fan 59 blows and dissipates heat to the rim during the welding process, thereby completing the adjustment of the rim angle and improving the subsequent welding structure 3 to clamp rims at different angles.

[0056] In the second embodiment of the present invention, step 1, the rim is placed on the surface of the receiving plate 44 to receive the rim, and the rim is ensured not to fall off;

[0057] Step 2: Start the welding structure 3 and weld the rim placed on the receiving plate 44. Simultaneously, start the second motor 46 to move the two collection boxes 43 and the sliding plate 41 away from each other, and guide the debris generated by the welding into the collection box 43 for collection.

[0058] Step 3: When the two sliding plates 41 move away from each other, the four clamping plates 55 are brought together to clamp the rim placed on the receiving plate 44, so as to facilitate the subsequent angle adjustment of the rim;

[0059] Step 4: Start the third motor 52 to rotate and adjust the rim clamped in multiple directions by the four clamping plates 55, so that the welding structure 3 welds the rim being adjusted, completing the multi-directional clamping and welding of the rim.

[0060] Working principle: When the rim needs to be welded, the staff needs to place the rim on the top of the receiving plate 44, and then operate the control panel 2 to start the first motor 33 and drive the first screw rod 32, so that the threaded plate in the welding device 31 moves on the surface of the first screw rod 32 until the welding head on the welding device 31 is aligned with the rim placed on the receiving plate 44, and welding is performed.

[0061] Next, the two second motors 46 are started through the work control panel 2, so that the two second screw rods 45 rotate, and the two threaded blocks 47 move away from each other on the surfaces of the two second screw rods 45, and synchronously drive the two sliding plates 41 to move away from each other, and then drive the respective first swing plates 42 from the swinging state to the vertical state, and in the process of becoming the vertical state, each drive the two collection boxes 43 to move away from each other, so that the two collection boxes 43 slide on the outer ring surface of the receiving plate 44, thereby increasing the collection range of the collection box 43.

[0062] When the sliding plate 41 moves to adjust the size of the collection box 43, the movement of the sliding plate 41 will drive the triangular fixed plate 51 to move, and simultaneously drive the multi-directional clamping structure 5 as a whole to move away from each other. Since the side surfaces of the fixed plate 57 are respectively engaged with the side surfaces of the rim, when the two triangular fixed plates 51 move away from each other, the rotating plate 53 will be synchronously driven to move, and then the movement of the rotating plate 53 will drive the sliding post 58 to slide inside the fixed plate 57, so that the side surface of the rotating plate 53 rotates and the second swinging plate 54 connected to the four second swinging plates 54 changes from a swinging state to a slightly swinging state (please refer to the details). Figure 9 ), then the four second swing plates 54 will drive the four clamping plates 55 to gather inward during the swing process, and will simultaneously drive the four limit plates 56 to slide inside the fixed plate 57, so that the fans 59 installed on the surfaces of the limit plates 56 are aligned with the rim, and the four clamping plates 55 will clamp the rim placed on the receiving plate 44 in multiple directions;

[0063] Then, when the four clamping plates 55 clamp the rim in multiple directions, the staff starts the third motor 52 to rotate the third motor 52 fixedly connected to the output end, which will then drive the four second swing plates 54 to rotate, and will synchronously drive the rim in the multiple-direction clamping of the four clamping plates 55 to rotate, thereby adjusting the angle of the clamped rim by the four clamping plates 55, and the staff can also control the control panel 2 to start each fan 59, so that the wind blown by the fan 59 can blow and dissipate heat to the rim during the welding process, thereby completing the rim angle adjustment and multi-direction clamping.
