Description

Technical Field

[0001] This application relates to the technical field of sheet metal processing, and in particular to a quick-release fixing fixture for processing sheet metal for passenger vehicles. Background Technology

[0002] Reference Figure 1 A bus body panel 01 includes a bent plate 011 and mounting strips 012. Two mounting strips 012 are arranged parallel to each other along the length of the inner arc wall of the bent plate 011. To facilitate the installation of bolts during subsequent assembly, holes need to be drilled at specific locations on the mounting strips 012.

[0003] Currently, in order to facilitate the installation of the board, the drilling direction needs to be perpendicular to the inner wall of the bent board. However, since the board is curved and the drilling direction of the drill bit is fixed, the placement angle of the bent board needs to be adjusted during drilling so that the position and angle of the installation strip can be matched with the drilling direction of the drill bit.

[0004] Regarding the aforementioned technologies, the inventors believe that this method of adjusting the sheet metal requires removing the bus sheet metal from the clamp and re-clamping it to adjust the angle of the bent sheet metal. This method is inconvenient and reduces the processing efficiency of the bus sheet metal. Utility Model Content

[0005] To facilitate angle adjustment of sheet metal and improve processing efficiency, this application provides a quick-release fixing fixture for processing sheet metal for passenger vehicles.

[0006] The quick-release fixing fixture for processing passenger car sheet metal provided in this application adopts the following technical solution:

[0007] A quick-release fixing fixture for processing passenger car sheet metal includes a base plate, a supporting rotating plate, a supporting frame, a rotating shaft, a linkage plate, and fixing components. The supporting frame is disposed on the top surface of the base plate, the rotating shaft is rotatably mounted on the supporting frame, the linkage plate is disposed on the bottom surface of the supporting rotating plate, and the linkage plate is connected to the rotating shaft. The base plate is provided with a drive source for driving the rotating plate to rotate. The fixing components are arranged in two rows parallel to each other along the length of the top surface of the supporting rotating plate. The fixing components include a fixed spinning cylinder and a spinning rod. The fixed spinning cylinder is disposed on the supporting rotating plate, and the spinning rod is throttle-connected to the fixed spinning cylinder. The spinning rod is inclined to the supporting rotating plate.

[0008] By adopting the above technical solution, before processing, the bent plate is placed on the support rotating plate, and the fixed spinning cylinder is activated. Under its drive, the spinning rod is pressed against the bent plate, thus fixing the bent plate. The drive source is activated, causing the support rotating plate to rotate until the angle of one of the mounting strips corresponds to the drilling direction. After drilling one side of the mounting strip is completed, the drive source drives the support rotating plate to rotate until the other mounting strip corresponds to the drilling direction. Through the cooperation of the base plate, support rotating plate, support frame, rotating shaft, linkage plate, and fixing components, the bent plate can be quickly clamped and its angle adjusted, which has the effect of facilitating the angle adjustment of the sheet metal and improving the processing efficiency of the sheet metal.

[0009] Optionally, a plurality of abutment blocks are provided on both sides of the support plate in the width direction, and the plurality of abutment blocks are provided in a one-to-one correspondence with a plurality of fixed spinning cylinders. The top of the abutment block is provided with an abutment slope, and a fixed elastic block is provided on the side of the spinning rod near the abutment slope. A clamping rod is provided on the side of the spinning rod where the fixed elastic block is located.

[0010] By adopting the above technical solution, the abutting slope of the abutting block supports the outer arc wall of the bent plate, and the fixed elastic block abuts against the inner arc wall of the bent plate during the clamping process. The abutting rod presses the bent plate tightly against the abutting arc surface, thereby reducing the possibility of surface damage to the bent plate while improving its stability.

[0011] Optionally, the support frame is provided in several groups, and one rotating shaft is rotatably provided on each support frame. The several support frames are located on the same straight line, and the several rotating shafts are arranged collinearly. Adjacent rotating shafts are connected by a coupling.

[0012] By adopting the above technical solution, the arrangement of several support brackets divides the device into several individual units, which makes it convenient for operators to select the appropriate number of support brackets according to the length of the bent plate and connect them end to end, thus expanding the applicability of the device.

[0013] Optionally, the fixing component further includes snap-fit ​​blocks, two of which are provided at the ends of the two outermost supporting rotating plates that are far apart from each other. The two snap-fit ​​blocks on the same supporting rotating plate correspond one-to-one with the ends of the two mounting strips. A snap-fit ​​groove is provided at the end of the snap-fit ​​block near the inner side of the supporting rotating plate. The shape of the snap-fit ​​groove corresponds to the end of the mounting strip. The supporting rotating plate is provided with a driving member for driving the snap-fit ​​blocks to move along the length direction of the supporting rotating plate.

[0014] By adopting the above technical solution, after the bent plate is placed on the supporting rotating plate, the driving component drives the snap-fit ​​block to move in the direction of the bent plate until the end of the mounting strip is embedded in the snap-fit ​​groove of the snap-fit ​​block, thereby achieving the limitation of the length direction of the bent plate and further reducing the possibility of the bent plate shaking during the drilling process.

[0015] Optionally, several mounting plates are provided at both ends of the bottom surface of the support plate in the width direction, and each mounting plate is provided with an abutment rod. A first buffer block is provided at the bottom end of the abutment rod. Several second buffer blocks are provided on both sides of the top end of the support frame in the width direction, and the several first buffer blocks and several second buffer blocks are provided in a one-to-one correspondence.

[0016] By adopting the above technical solution, when the supporting rotating plate rotates to a certain angle, the first buffer block and the second buffer block come into contact and limit the rotation angle of the supporting rotating plate. The setting of the first buffer block and the second buffer block reduces the possibility of damage to the support frame and the supporting rotating plate during rotation.

[0017] Optionally, a plurality of pressing rotating rods are rotatably provided on both sides of the supporting rotating plate in the width direction, and a pressing block is provided at the end of the pressing rotating rod, and a rotating handle is provided on the pressing rotating rod.

[0018] By adopting the above technical solution, rotating the handle causes the clamping block to press against the mounting strip, further improving the connection stability between the bending plate and the supporting plate.

[0019] Optionally, several sets of limiting components are provided on both sides of the support plate in the width direction. The limiting components include a push handle, a limiting sleeve, and a limiting elastic block. One end of the limiting sleeve is slidably disposed on the edge of one side of the support plate in the width direction. The push handle is disposed at the end of the limiting sleeve away from the support plate. The limiting elastic block is disposed at the end of the limiting sleeve away from the push handle.

[0020] By adopting the above technical solution, rotating the push handle causes the limiting sleeve to move towards the edges on both sides of the bending edge under the drive, until the limiting elastic block presses against the edge of the bending plate, thus fixing the bending plate and further reducing the possibility of the bending plate shaking during drilling.

[0021] Optionally, the limiting assembly further includes an adjusting screw, one end of which is threaded into the limiting sleeve, and the end of the adjusting bolt away from the push handle is connected to the limiting elastic block.

[0022] By adopting the above technical solution, the overall length of the limiting component can be adjusted by turning the adjusting screw for bending plates of different widths, thus expanding the applicability of the device.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Through the cooperation of the base plate, supporting plate, support frame, rotating shaft, linkage plate and fixing components, the bending plate can be quickly clamped and the angle adjusted, which can facilitate the angle adjustment of the plate and improve the processing efficiency of the plate.

[0025] 2. The arrangement of several support brackets divides the device into several individual units, making it easier for operators to select the appropriate number of support brackets according to the length of the bent plate, thus expanding the applicability of the device;

[0026] 3. The first and second buffer blocks reduce the possibility of damage to the support frame and the rotating plate during rotation. Attached Figure Description

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be further described in detail below. Embodiments of this application provide a quick-release fixing fixture for processing bus sheet metal, which facilitates angle adjustment of the sheet metal and improves processing efficiency.

[0035] Reference Figure 2-4 A quick-release fixing fixture for processing bus sheet metal includes a base plate 1, support brackets 2, a support rotating plate 3, a fixing component 4, and a limiting component 5. Several support brackets 2 are arranged on the top surface of the base plate 1, and the support brackets 2 are located on the same straight line. Figure 5 , Figure 6 The support frame 2 is provided with a bearing seat 6, and a rotating shaft 7 is rotatably connected to the support frame 2 via the bearing seat 6. The direction of the rotating shaft 7 is parallel to the length direction of the support frame 2, and a coupling 8 for transmission connection is provided between several adjacent rotating shafts 7.

[0036] Reference Figure 4 and Figure 5 Each support plate 3 is positioned above each support frame 2, and the length of the support plate 3 is aligned with the length of the support frame 2. Several linkage plates 9 are mounted on the bottom surface of the support plate 3, and each linkage plate 9 is connected to a corresponding rotating shaft 7. A rotating cylinder 10 is rotatably mounted on the base plate 1, and the output shaft of the rotating cylinder 10 is rotatably connected to the support plate 3.

[0037] Reference Figure 3 and Figure 4The fixing assembly 4 includes a fixing spinning cylinder 41, a spinning rod 42, a fixing elastic block 43, a clamping rod 44, a pressing rotating rod 45, a rotating handle 46, a clamping block 47, a limiting cylinder 48, and a locking block 49. Several fixing spinning cylinders 41 are arranged on the sides of the supporting rotating plate 3 along its length. One end of the spinning rod 42 is connected to the output shaft of the fixing spinning cylinder 41, and the setting direction of the spinning rod 42 is at an inclined angle to the supporting rotating plate 3. The fixing elastic block 43 is located at the end of the spinning rod 42 away from the fixing spinning cylinder 41, and on the side of the spinning rod 42 closest to the supporting rotating plate 3. When one end of the spinning rod 42 is pressed against the bending plate 011, the position of the fixing elastic block 43 corresponds to the position of the mounting strip 012. One clamping rod 44 is connected to each spinning rod 42 on the side closest to the supporting rotating plate 3. Combination Figure 6 Several abutment blocks 11 are connected to both sides of the top surface of the rotating plate 3 in the width direction. The abutment blocks 11 are arranged one-to-one with several fixed spinning cylinders 41. The top of the abutment block 11 is provided with an abutment slope 111, and the curvature of the abutment slope 111 corresponds to the curvature of the bending plate 011.

[0038] Reference Figure 3 Several clamping rotating rods 45 are rotatably arranged on both sides of the supporting rotating plate 3 in the width direction. One end of the clamping rotating rod 45 is provided with a rotating handle 46 for driving its rotation, and the other end is connected to the clamping block 47. When the clamping rotating rod 45 rotates to abut against the bent plate 011, the position of the clamping block 47 corresponds to the position of the mounting strip 012. The side of the clamping block 47 near the mounting strip 012 has a clamping groove 471 corresponding to the shape of the mounting strip 012.

[0039] Reference Figure 4 Two limiting cylinders 48 are provided on the top surfaces of two mutually distant supporting rotating plates 3. The limiting cylinders 48 on the two supporting rotating plates 3 are located at the ends of the two supporting rotating plates 3 that are far apart from each other. The output shaft of the supporting cylinder extends along the length direction of the supporting rotating plate 3. One locking block 49 is drivenly connected to the output shaft of each supporting cylinder. The end of the locking block 49 away from the limiting cylinder 48 has a locking groove 491. The two locking blocks 49 located on the same supporting rotating plate 3 are correspondingly provided with the two mounting strips 012 one by one. The shape of the locking groove 491 corresponds to the shape of the end of the mounting strip 012.

[0040] Reference Figure 5 and Figure 6On both sides of the bottom width direction of the supporting rotating plate 3, there are several mounting plates 12. Each mounting plate 12 is connected to an abutment rod 13, and the bottom end of the abutment rod 13 is provided with a first buffer block 14. On both sides of the top width direction of the supporting frame 2, there are several second buffer blocks 15, and the several second buffer blocks 15 are arranged in a one-to-one correspondence with the several first buffer blocks 14. The arrangement of the first buffer blocks 14 and the second buffer blocks 15 reduces the possibility of damage to the supporting frame 2 and the supporting rotating plate 3 during the rotation of the supporting rotating plate 3.

[0041] Reference Figure 3 A limiting component 5 is disposed on the supporting rotating plate 3. The limiting component 5 includes a push handle 51, a limiting sleeve 52, an adjusting screw 53, and a limiting elastic block 54. Several limiting sleeves 52 are slidably disposed on both sides of the supporting rotating plate 3 in the width direction, and the vertical plane of the limiting sleeves 52 is perpendicular to the side of the supporting rotating plate 3 in the length direction. One end of the adjusting screw 53 is threaded into the limiting sleeve 52, and the end of the adjusting screw 53 near the supporting rotating plate 3 extends out of the limiting sleeve 52 and is connected to the limiting elastic block 54.

[0042] Reference Figure 2-4 When processing the bus sheet metal 01, the bent plate 011 is placed above several supporting rotating plates 3. The outer arc wall of the bent plate 011 is supported on the abutment slope 111 of the abutment block 11, thus supporting the bent plate 011. The limiting cylinder 48 drives the locking block 49 to move along the length direction of the supporting rotating plate 3, and the end of the mounting strip 012 is embedded in the locking groove 491 of the corresponding locking block 49, thus limiting the position of both ends of the bent plate 011 in the length direction. The fixed spinning cylinder 41 is activated, and the spinning rod 42 rotates and presses against the bent plate 011 under the drive of the fixed spinning cylinder 41. The fixed elastic block 43 is pressed against the corresponding mounting rod, and the pressing rod 44 presses the bent plate 011 against the abutment slope 111 of the abutment block 11. At the same time, the rotating handle 46 is rotated, and the pressing rotating rod 45 rotates and presses against the inner arc wall of the bent plate 011. The clamping block 47 abuts against the corresponding mounting strip 012, and the mounting strip 012 is embedded in the clamping groove 471 of the clamping block 47. The setting of the fixing component 4 improves the connection stability between the bending plate 011 and the supporting rotating plate 3. It reduces the possibility of the bending plate 011 shaking during drilling.

[0043] Reference Figure 3 By rotating the push handle 51, the limiting sleeve 52 moves towards the edges on both sides of the bending plate 011 in the width direction, and the limiting elastic block 54 abuts against the edge of the bending plate 011, thereby further fixing the bending plate 011. For bending plates 011 of different widths, the position of the limiting elastic block 54 can be adjusted by turning the adjusting screw 53, thus expanding the applicability of the device.

[0044] Reference Figure 4 After the bent plate 011 is fixed, the rotary cylinder 10 is started, driving the supporting rotating plate 3 and the bent plate 011 fixed above it to rotate until the angle of one of the mounting strips 012 corresponds to the angle of the drill bit. After drilling one side of the mounting strip 012 is completed, the rotary cylinder 10 is started, so that the angle of the other mounting strip 012 corresponds to the angle of the drill bit, which facilitates the subsequent drilling operation.

[0045] The implementation principle of a quick-release fixing fixture for processing bus sheet metal in this embodiment is as follows: When processing bus sheet metal 01, the bent plate 011 is placed on the supporting rotating plate 3. The snap-fit ​​block 49 moves, and the end of the mounting strip 012 is embedded in the corresponding snap-fit ​​groove 491. The fixing spinning cylinder 41 is activated, and the fixing elastic block 43 is pressed against the corresponding mounting rod. At the same time, the pressing rotating rod 45 presses against the bent plate 011. The push handle 51 is rotated, and the limiting sleeve 52 moves towards the bent plate 011, and the limiting elastic block 54 abuts against the edge of the bent plate 011, thereby further fixing the bent plate 011.

[0046] After the bending plate 011 is fixed, the rotary cylinder 10 is started, driving the supporting rotating plate 3 and the bending plate 011 fixed on it to rotate until the angle of one of the mounting strips 012 corresponds to the angle of the drill bit, which facilitates the subsequent drilling operation.

[0047] 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.
