Description

Technical Field

[0001] This application relates to the technical field of workpiece production, and in particular to a fixture and method for correcting the angle of a cabinet workpiece. Background Technology

[0002] During the manufacturing of components for equipment such as server racks, specific angle requirements exist for these components. The angles at which these components are machined significantly impact the integrity and usability of the equipment. (Refer to...) Figure 1 , Figure 1 This is a structural schematic diagram illustrating a cabinet component 01. The cabinet component 01 includes a mounting part 011 and bent parts 012 disposed at both ends of the mounting part 011 along its length. The two bent parts 012 are located on the same side of the mounting part 011, and the included angles between the two bent parts 012 and the mounting part 011 are equal. The ends of the bent parts 012 away from the mounting part 011 are set at acute angles. The mounting part 011 has a connecting port 013 and several mounting holes 014.

[0003] During the processing of rack-mount components, a pressure device is typically used to bend the two ends of a flat raw material to the same side, pressing it into a rack-mount component with a roughly required angle. However, the inner bend angle of the rack-mount component may not meet the usage standard after initial processing, requiring adjustment of the component angle. First, the distance between the two sharp corners of the rack-mount component needs to be measured. If the distance is greater than the standard distance, the two sharp corners of the rack-mount component need to be tapped towards each other until the distance reaches the predetermined value. If the distance is less than the standard distance, the two sharp corners of the rack-mount component need to be tapped away from each other from the inside.

[0004] Regarding the aforementioned technologies, the inventors believe that during the angle correction process of the aforementioned cabinet workpiece, on the one hand, adjusting the bent parts by tapping can easily lead to unequal angles between the two bent parts and the mounting part; on the other hand, because the ends of the bent parts are acute-angled, their structural strength is low, and irregular deformation is prone to occur during tapping. In addition, manually measured distances also have certain errors, resulting in the repaired cabinet workpiece not meeting the usage standards and affecting the normal use of the cabinet workpiece. Summary of the Invention

[0005] In order to achieve precise shaping of cabinet workpieces, this application provides a cabinet workpiece angle correction fixture and method.

[0006] The technical solution provided in this application for a fixture and method for correcting the angle of a cabinet workpiece is as follows:

[0007] A fixture for correcting the angle of a cabinet workpiece includes a base plate, a frame, a trimming assembly, and a clamping assembly. The frame is connected to the base plate. The clamping assembly includes a clamping plate disposed below the frame and a drive source for driving the clamping plate to move vertically. An arc-shaped sliding rod is connected to each of the two vertical sections of the frame, and a transverse connecting rod connects the two arc-shaped sliding rods. The center positions of the two arc-shaped sliding rods correspond one-to-one with the bending points of the two bends and the mounting sections. The trimming assembly has one set on each arc-shaped sliding rod. The assembly includes an arc-shaped slider, a first clamping plate, and a second clamping plate. The arc-shaped slider is slidably connected to the arc-shaped slide rod. The first clamping plate is fixedly connected to the side of the arc-shaped slider near the base plate. The second clamping plate is slidably connected to the side of the arc-shaped slider near the base plate and is arranged parallel to the first clamping plate. The setting direction of the first clamping plate coincides with the radial direction of the arc-shaped slide rod. The gantry is provided with a first driving component for driving the two arc-shaped sliders to move synchronously in a direction that moves closer to or further away from each other.

[0008] By adopting the above technical solution, when trimming the cabinet workpiece, the workpiece is placed on the base plate and the mounting part is made to fit against the base plate. The clamping plate descends under the drive of the drive source and presses the mounting part firmly against the base plate. The specific positions of the two arc-shaped sliders on the arc-shaped slide rod are adjusted so that the first clamping plate connected to the arc-shaped slide rod fits against one side of the bent part. The specific position of the second clamping plate on the arc-shaped slider is adjusted so that the bent part is clamped between the first and second clamping plates. After fixing the bent part and the mounting part, the first drive component is activated. Under the action of the first drive component, the two arc-shaped sliders slide synchronously along the arc-shaped slide rod in directions that are closer to or further apart from each other. The first and second clamping plates bend the bent part to a suitable angle. Because the bent part is clamped between the first and second clamping plates, uneven force on the bent part during bending is avoided, preventing local deformation. Driven by the first drive assembly, the two arc-shaped sliders move simultaneously in directions closer to or further apart from each other, preventing different bending angles at the two bends. Through the cooperation of the base plate, gantry, trimming assembly, and clamping assembly, the cabinet workpiece is fixed and uniformly trimmed, achieving precise trimming of the cabinet workpiece shape.

[0009] Optionally, the arc-shaped slider has an arc-shaped through groove for accommodating the arc-shaped slide rod. A mounting block is connected to one end of the second clamping plate near the arc-shaped slider. An mounting groove is provided on one side of the arc-shaped slider near the second clamping plate. The mounting block is slidably disposed in the mounting groove. A locking waist-shaped hole is provided on the arc-shaped slider, located on the side wall of the arc-shaped slider adjacent to the mounting groove. The locking waist-shaped hole communicates with the mounting groove. A locking bolt is disposed in the locking waist-shaped hole. The locking bolt passes through the mounting block and extends out of the arc-shaped slider through the locking waist-shaped hole. A locking nut is threadedly connected to one end of the locking bolt extending out of the arc-shaped slider. The locking nut abuts against the side wall of the arc-shaped slider.

[0010] By adopting the above technical solution, when fixing the bent portion, the arc-shaped slider is first adjusted to a specific position on the arc-shaped slide rod, so that the first clamping plate is in contact with one side of the bent portion. The mounting block is pushed into the mounting groove on the arc-shaped slider until the second clamping plate is in contact with the other side of the bent portion. The locking bolt is inserted into the locking waist-shaped hole, and the locking bolt passes through the mounting block and extends out of the arc-shaped slider through the locking waist-shaped hole. The locking nut is used to lock the end of the locking bolt extending out of the arc-shaped slider. The first and second clamping plates facilitate the fixing of bent portions of different thicknesses by the trimming assembly, expanding the applicability of the device.

[0011] Optionally, a first anti-slip pad is provided on the bottom surface of the clamping plate, an alignment rod corresponding to the mounting hole is connected to the bottom surface of the clamping plate, and an alignment hole corresponding to the alignment rod is provided on the bottom plate.

[0012] By adopting the above technical solution, the first anti-slip pad increases the friction between the clamping plate and the mounting part, reducing the possibility of the cabinet workpiece sliding on the base plate when fixing it. As the clamping plate descends, the alignment rod passes through the mounting hole on the mounting part and embeds into the alignment hole on the base plate, achieving precise positioning of the cabinet workpiece.

[0013] Optionally, the first drive assembly includes a trimming motor, a bidirectional screw, and a drive slider. A drive block is provided on the gantry, and a second drive assembly for driving the drive block to move vertically is provided on the gantry. The trimming motor is connected to the drive block, and one end of the bidirectional screw is drivenly connected to the trimming motor. The bidirectional screw is horizontally arranged and has two threaded segments with opposite directions of rotation. Two drive sliders are provided on the bidirectional screw. The two drive sliders correspond one-to-one with the two threaded segments with opposite directions of rotation on the bidirectional screw and are threadedly connected. The two drive sliders correspond one-to-one with the two arc-shaped sliders and are rotatably connected.

[0014] By adopting the above technical solution, the adjustment motor starts and drives the bidirectional screw to rotate. Under the drive of the bidirectional screw, the two drive sliders move towards or away from each other. The two arc-shaped sliders, connected to the drive sliders, slide along the two arc-shaped sliding rods towards or away from each other, achieving equal angle adjustment of the two bends. The drive block moves vertically under the drive of the second drive assembly, ensuring that the height of the first drive assembly always corresponds to the two arc-shaped sliders.

[0015] Optionally, the second driving component includes a drive motor, a drive screw, a guide block, and a guide rod. The drive screw is vertically rotatably connected to the base plate, the drive motor is connected to the gantry, the top end of the drive screw is drive-connected to the drive motor, the drive screw is threadedly connected to the drive block, the guide rod is vertically connected to the base plate, the guide block is rotatably connected to the end of the bidirectional screw away from the trimming motor, and the guide rod passes through the guide block and is slidably connected to the guide rod.

[0016] By adopting the above technical solution, the drive motor starts and drives the drive screw to rotate. The drive block moves in the vertical direction under the drive of the drive screw. The guide block and guide rod guide and limit the movement of the first drive component in the vertical direction.

[0017] Optionally, the edge of the first clamping plate is connected to a first connecting plate, the side of the first connecting plate near the second clamping plate is connected to a connecting bolt, the edge of the second clamping plate is connected to a second connecting plate, and the connecting bolt passes through the second connecting plate and is threaded with a connecting nut.

[0018] By adopting the above technical solution, when fixing the bent part, the connecting bolt passes through the second connecting plate, and the connecting nut is used to lock the connecting bolt, which improves the connection stability between the first clamping plate and the second clamping plate and the bent part.

[0019] Optionally, an angle measuring arc plate is vertically arranged on the base plate, and angle scale lines are arranged along the circumference on the angle measuring arc plate. The center position of the angle measuring arc plate is set to correspond to the bending point of one of the bending parts and the mounting part.

[0020] By adopting the above technical solution, the setting of the angle measuring arc plate makes it convenient for operators to intuitively and accurately observe the bending angle between the bending part and the installation part, and facilitates bending the bending part to a specific angle.

[0021] A method for correcting the angle of a cabinet workpiece includes the following steps:

[0022] Fixing the workpiece: Place the cabinet workpiece on the base plate, and lower the clamping plate to press the mounting part of the cabinet workpiece onto the base plate;

[0023] Locking the bent part: Adjust the arc-shaped slider to a suitable position on the arc-shaped slide rod so that the first clamping plate fits against one side of the bent part, and install the second clamping plate at a suitable position on the arc-shaped slider so that the bent part is clamped between the first clamping plate and the second clamping plate;

[0024] Trimming the workpiece: The first drive assembly is activated, driving two arc-shaped sliders to move synchronously towards or away from each other on the arc-shaped slide bar. The second drive assembly drives the first drive assembly to move vertically. The two bent parts are bent under the action of the first clamping plate and the second clamping plate. The angle between the bent parts and the mounting parts is accurately observed through the angle display arc plate.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Through the cooperation of the base plate, gantry, trimming components and clamping components, the cabinet workpieces are fixed and uniformly trimmed, achieving the effect of precise trimming of the cabinet workpiece shape;

[0027] 2. The first anti-slip pad increases the friction between the pressure plate and the mounting part, reducing the possibility of the cabinet workpiece sliding on the base plate when fixing the cabinet workpiece;

[0028] 3. The angle measuring arc plate facilitates operators to intuitively and accurately observe the bending angle between the bending part and the installation part. Attached Figure Description

The two arc-shaped sliding rods 7 are symmetrically arranged about the central axis of the gantry 2, and a transverse connecting rod 8 is fixedly connected to the ends of the two arc-shaped sliding rods 7 that are close to each other. When the cabinet workpiece 01 is placed on the base plate 1 and the mounting holes 014 on the mounting part 011 correspond one-to-one with the alignment holes 101 on the base plate 1, the bending points between the two bent parts 012 and the mounting part 011 correspond one-to-one with the center positions of the two arc-shaped sliding rods 7. The output shaft of the clamping cylinder 31 passes through the transverse connecting rod 8 and is slidably connected to it.

The length direction of the installation groove 411 is perpendicular to the plane where the first clamping plate 42 is located, and one end of the installation groove 411 passes through the end of the arc-shaped slider 41 away from the first clamping plate 42.

[0043] Reference Figure 5 and Figure 6A mounting block 46 is fixedly connected to one end of the second clamping plate 43 near the arc-shaped slider 41. The mounting block 46 is slidably connected in the mounting groove 411. A locking waist-shaped hole 413 is provided on the arc-shaped slider 41, passing through opposite sides of the arc-shaped slider 41 and communicating with the mounting groove 411. The length direction of the locking waist-shaped hole 413 is parallel to the length direction of the mounting groove 411. A locking bolt 10 is inserted into the locking waist-shaped hole 413. One end of the locking bolt 10 passes through the mounting block 46 and extends out of the arc-shaped slider 41 through the locking waist-shaped hole 413. A locking nut 11 is threadedly connected to the end of the locking bolt 10 extending out of the arc-shaped slider 41. The locking nut 11 abuts against the side wall of the arc-shaped slider 41, thus fixing the mounting block 46 in the mounting groove 411.

[0044] Reference Figure 7 A first connecting plate 12 is fixedly connected to the edge of the first clamping plate 42 in the width direction. The first connecting plate 12 is located on the side of the first clamping plate 42 away from the arc-shaped slider 41.

The second connecting plate 14 is correspondingly arranged with the first connecting plate 12. The connecting bolt 13 passes through the second connecting plate 14 and is threaded with a connecting nut 15. The connecting nut 15 abuts against the second connecting plate 14, thereby realizing the connection between the first clamping plate 42 and the second clamping plate 43.

[0045] Reference Figure 4 The second drive assembly 6 is disposed between the gantry 2 and the base plate 1. The second drive assembly 6 includes a drive motor 61, a drive screw 62, a drive block 63, a guide block 64, and a guide rod 65. The drive motor 61 is fixedly connected to the top of the horizontal part of the gantry 2. One end of the drive screw 62 is drivenly connected to the output shaft of the drive motor 61, and the other end of the drive screw 62 is rotatably connected to the top surface of the base plate 1. The drive screw 62 is vertically arranged. The guide rod 65 is vertically fixedly connected between the horizontal part of the gantry 2 and the base plate 1. The guide block 64 is slidably connected to the guide rod 65, and the drive block 63 is threadedly connected to the drive screw 62. A guide rail 16 is horizontally fixedly connected between the drive block 63 and the guide block 64. A guide groove 17 is formed on the guide rail 16 along its length direction.

[0046] Reference Figure 4 and Figure 5The first drive assembly 5 is mounted on the guide rail 16 and includes a trimming motor 51, a bidirectional screw 52, ​​a drive slider 53, and a rotating rod 54. The trimming motor 51 is fixedly connected to one end of the guide rail 16 along its length, and its output shaft extends horizontally and is connected to one end of the bidirectional screw 52. The bidirectional screw 52 has two threaded sections with opposite directions of rotation. A mounting plate is fixedly connected to the end of the guide rail 16 away from the trimming motor 51, and the end of the bidirectional screw 52 away from the trimming motor 51 is rotatably connected to the mounting plate. One drive slider 53 is threaded onto each of the two threaded sections of the bidirectional screw 52 with opposite directions of rotation, and one end of the drive slider 53 is slidably connected to the guide groove 17 of the guide rail 16. One rotating rod 54 is rotatably connected to each drive slider 53 on the side away from the guide rail 16. The rotating rod 54 is horizontally positioned, and the end of the rotating rod 54 away from the drive slider 53 is rotatably connected to an arc-shaped slider 41.

[0047] Reference Figure 1-3 A method for correcting the angle of a cabinet workpiece includes the following steps: When adjusting the cabinet workpiece 01, the cabinet workpiece 01 is placed on the base plate 1 and the mounting part 011 is made to fit against the base plate 1. A plurality of mounting holes 014 on the mounting part 011 correspond one-to-one with a plurality of alignment holes 101 on the base plate 1. A clamping cylinder 31 is activated, and a clamping plate 32 descends under the drive of the clamping cylinder 31, pressing the mounting part 011 of the cabinet workpiece 01 against the base plate 1. A plurality of alignment rods 34 on the clamping plate 32 pass through the plurality of mounting holes 014 on the mounting part 011 and are embedded in the plurality of alignment holes 101 on the base plate 1, preventing the cabinet workpiece 01 from shifting on the base plate 1. The first anti-slip pad 33 increases the friction between the clamping plate 32 and the mounting part 011, improving the connection stability of the cabinet workpiece 01, and also preventing the possibility of deformation of the mounting part 011 due to a hard connection between the clamping plate 32 and the mounting part 011.

[0048] Reference Figure 5 and Figure 4 The trimming motor 51 is started, and the two drive sliders 53 move along the length of the guide groove 17 along the bidirectional screw 52 and the guide groove 17 on the guide rail 16, moving towards or away from each other. The two arc-shaped sliders 41 slide on the arc-shaped slide rod 7. The setting of the abutting roller 45 reduces the friction between the arc-shaped sliders 41 and the arc-shaped slide rod 7, facilitating the movement of the arc-shaped sliders 41 on the arc-shaped slide rod 7. The drive motor 61 starts and drives the drive screw 62 to rotate. The guide rail 16 moves vertically under the drive of the drive screw 62 and the limiting and guiding action of the guide rod 65 and the guide block 64, so that the first drive assembly 5 can adapt to the height of the arc-shaped sliders 41 on the arc-shaped slide rod 7.

[0049] Reference Figure 5-7The first clamping plate 42 moves with the arc-shaped slider 41 until it is in contact with one side of the bent portion 012. The mounting block 46 on the second clamping plate 43 is pushed into the mounting groove 411, making the second clamping plate 43 contact with the other side of the bent portion 012. The locking bolt 10 is passed through the locking slot 413 on the arc-shaped slider 41 and secured, thus fixing the mounting block 46 and the second clamping plate 43. The connecting bolt 13 passes through the second connecting plate 14, and the end of the connecting bolt 13 passing through the second connecting plate 14 is locked using the connecting nut 15, improving the connection strength between the first clamping plate 42 and the second clamping plate 43 and the bent portion 012. The second anti-slip pad 44 increases the friction between the first clamping plate 42 and the second clamping plate 43 and the bent portion 012, while also reducing the possibility of the first clamping plate 42 and the second clamping plate 43 damaging the bent portion 012.

[0050] Reference Figure 4-6 After the bending portion 012 and the mounting portion 011 are fixed, the trimming motor 51 is started, driving the two drive sliders 53 to move along the length of the guide rail 16 in a direction that approaches or moves away from each other. The arc-shaped slider 41 moves synchronously with the drive sliders 53 in the same direction. The drive motor 61 is started, and the guide rail 16 moves vertically under its drive, so that the height of the guide rail 16 is adapted to the height of the arc-shaped slider 41. The bending portion 012, clamped between the first clamping plate 42 and the second clamping plate 43, bends under the action of both. Since the bidirectional screw 52 synchronously drives the two sets of trimming components 4 to move, the possibility of inconsistent angles between the two bending portions 012 and the mounting portion 011 is reduced. The angle between the bending portion 012 and the mounting portion 011 is visually measured by the angle measuring arc plate 9 connected to the base plate 1 until the bending portion 012 is bent to the standard position.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
