Description

Technical Field

[0001] This invention relates to the field of press-fitting equipment technology, specifically an automatic press-fitting device for a brake caliper assembly production line. Background Technology

[0002] The press-fitting device is one of the core workstations on the brake caliper assembly line. It is mainly used to press components such as guide pins, pistons, dust covers, and mufflers into designated positions on the caliper body or bracket with precise force and displacement. Before pressing the brake caliper, appropriate positioning fixtures are required to fix the caliper in place, ensuring that the position to be pressed corresponds to the press-fitting head, and preventing movement or deformation during the pressing process.

[0003] The commonly used positioning fixtures for fixing brake calipers employ lever, pneumatic, or hydraulic clamping methods. However, the problem is that the positioning fixture itself is in a fixed state. When pressing on components such as guide pins, pistons, and mufflers at different positions on the brake caliper, the placement angle of the brake caliper needs to be constantly changed to ensure that the pressing point corresponds one-to-one with the pressing head. Therefore, the clamping position between the brake caliper and the fixture needs to be disassembled, installed, and adjusted according to requirements. This is extremely detrimental to fast and efficient pressing processes.

[0004] In view of this, this technical solution designs an automatic pressing device for a brake caliper assembly production line. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic pressing device for a brake caliper assembly production line to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automatic pressing device for a brake caliper assembly line includes a pressing frame; a pressing lifting unit, a multi-head pressing unit, and an adjustable positioning unit are arranged sequentially from top to bottom on the inner side of the pressing frame; the multi-head pressing unit is installed at the bottom of the pressing lifting unit, and the adjustable positioning unit is distributed alternately with the multi-head pressing unit; the brake caliper to be pressed is placed on the adjustable positioning unit for clamping and fixing, and then the pressing lifting unit controls the multi-head pressing unit to move up and down to assemble and press the brake caliper placed on the adjustable positioning unit; The pressing and lifting unit includes a main lifting pressing hydraulic cylinder fixedly installed at the top center of the pressing machine frame. The bottom of the main lifting pressing hydraulic cylinder is connected to a horizontally distributed lifting plate through a hydraulic rod. The multi-head pressing unit is installed at the bottom of the lifting plate. The main lifting pressing hydraulic cylinder controls the lifting and lowering of the hydraulic rod at the bottom, thereby controlling the multi-head pressing unit to perform pressing operations on the parts on the brake caliper. The multi-head pressing unit includes a pressing head moving assembly mounted on the hydraulic rod at the bottom of the main lifting pressing hydraulic cylinder. The pressing head moving assembly moves in any direction along the horizontal plane. The bottom of the pressing head moving assembly is rotatably connected to a multi-pressing head assembly via a pressing head adjusting motor. The multi-pressing head assembly is equipped with different types of pressing heads. The pressing head moving assembly and the pressing head adjusting motor are used to adjust the placement angle and position of the multi-pressing head assembly, and control the pressing head to be used to perform precise fitting pressing of the corresponding parts of the brake caliper positioned on the adjustable positioning unit. The adjustable positioning unit includes a support adjustment assembly fixedly installed on one side of the press frame. A hydraulic clamping assembly is installed on the top of the support adjustment assembly. The support adjustment assembly is used to automatically adjust the three-dimensional placement angle of the hydraulic clamping assembly, so that the brake caliper in the clamping state can be adjusted to any position to be pressed without disassembly, so that it can be vertically aligned with the multi-press head assembly on the upper side, thereby realizing fast and efficient multi-part multi-position press operation.

[0007] A control box is installed on one side of the bottom of the pressing machine frame. The control box serves as the control center of the entire device, coordinating and controlling the stable and efficient operation of the entire device. The pressing machine frame is equipped with a PLC control system, power supply system, etc., which are wirelessly or wiredly connected to the aforementioned electrical components, thereby realizing remote operation as the control center.

[0008] Compared with the prior art, the beneficial effects of the present invention are: by adjusting the support adjustment component in the adjustable positioning unit, the three-dimensional placement angle of the brake caliper is automatically adjusted so that the position to be pressed is always perpendicular to the pressing head, without the need to disassemble the clamp, greatly reducing the adjustment time and improving the pressing efficiency.

[0009] By integrating multiple pressing heads into a multi-head pressing unit, and achieving rapid switching and precise positioning through pressing head moving components and adjusting motors, it can adapt to the pressing needs of different parts and reduce tool change time.

[0010] The hydraulic clamping assembly employs a two-stage clamping plate design, combined with hydraulic transmission, and adaptive brake caliper shape to ensure uniform clamping force and prevent workpiece movement or deformation during pressing.

[0011] This assembly device operates in a coordinated manner through a control box, realizing a fully automated process from clamping and angle adjustment to pressing. It is suitable for multi-variety, small-batch production, improving the flexibility and safety of the assembly line. Attached Figure Description

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Please see Figures 1-2 An automatic pressing device for a brake caliper assembly line includes a pressing frame 10; the inner side of the pressing frame 10 is provided with a pressing lifting unit, a multi-head pressing unit 11, and an adjustable positioning unit 12 arranged sequentially from top to bottom; the multi-head pressing unit 11 is installed at the bottom of the pressing lifting unit, and the adjustable positioning unit 12 is distributed at intervals with the multi-head pressing unit 11. The brake caliper to be pressed is placed on the adjustable positioning unit 12 for clamping and fixing, and then the pressing lifting unit controls the multi-head pressing unit 11 to move up and down to assemble and press the brake caliper placed on the adjustable positioning unit 12. The pressing and lifting unit includes a main lifting pressing hydraulic cylinder 16 fixedly installed at the top center of the pressing frame 10. The bottom of the main lifting pressing hydraulic cylinder 16 is connected to a horizontally distributed lifting base plate 17 via a hydraulic rod. The multi-head pressing unit 11 is installed at the bottom of the lifting base plate 17. The main lifting pressing hydraulic cylinder 16 controls the lifting of the hydraulic rod at the bottom, thereby controlling the multi-head pressing unit 11 to perform pressing operations on the parts on the brake caliper. The multi-head pressing unit 11 includes a pressing head moving assembly 13 installed on the hydraulic rod at the bottom of the main lifting pressing hydraulic cylinder 16. The pressing head moving assembly 13 can move in any direction along the horizontal plane. The bottom of the pressing head moving assembly 13 is rotatably connected to a multi-pressing head assembly through a pressing head adjusting motor 59. The multi-pressing head assembly is equipped with different types of pressing heads. The pressing head moving assembly 13 and the pressing head adjusting motor 59 are used to adjust the placement angle and position of the multi-pressing head assembly, and control the pressing head to be used to perform precise fitting pressing of the corresponding parts of the brake caliper positioned on the adjustable positioning unit 12. The adjustable positioning unit 12 includes a support adjustment assembly fixedly installed on one side of the press frame 10. A hydraulic clamping assembly 14 is installed on the top of the support adjustment assembly. The support adjustment assembly is used to automatically adjust the three-dimensional placement angle of the hydraulic clamping assembly 14, so that the brake caliper in the clamping state can be adjusted to any position to be pressed without disassembly, so that it can be vertically aligned with the multi-press head assembly on the upper side, thereby realizing fast and efficient multi-part multi-position press operation.

[0027] A control box 15 is installed on one side of the bottom of the pressing frame 10. The control box 15 serves as the control center of the entire device, coordinating and controlling the stable and efficient operation of the entire device. The pressing frame 10 is equipped with a PLC control system, power supply system, etc., which are wirelessly or wiredly connected to the aforementioned electrical components, thereby realizing remote operation as the control center.

[0028] In this embodiment of the invention, lifting base plate 17 extends outward from all four corners and is equipped with lifting collars 18 via connecting rods. The lifting collars 18 are fitted onto four sets of support columns 19 distributed at the four corners of the press frame 10. The lifting collars 18 slide on the support columns 19 to increase the stability of the lifting base plate 17 when it is raised or lowered. A side plate is installed on the press frame 10 located on one side of the support adjustment component. The fixed end of the support adjustment component is fixedly connected to the side plate. The support adjustment component is installed and positioned by one side of the side plate, ensuring that there is sufficient and unobstructed rotation and adjustment space below the support adjustment component.

[0029] It should be noted that the support column 19 provides a sliding lifting path for the lifting collar 18, while also providing support for the overall stability of the press frame 10. The bottom of the press frame 10 is positioned and fixed by anchor bolts or support frame, which are not shown in the figure. The specific fixing method can be designed according to the ground structure used, and will not be described in detail here.

[0030] In one example of the present invention, such as Figure 1 , Figure 6 , Figure 7 The pressing head moving assembly 13 includes a connecting column installed at the end of the hydraulic rod at the bottom of the main lifting pressing hydraulic cylinder 16. An X-axis moving part is connected to the bottom of the connecting column, and a Y-axis moving part is connected to the bottom of the X-axis moving part. The bottom of the Y-axis moving part is connected to the top of the pressing head adjusting motor 59 through a connecting rod. That is, under the movement of the X-axis moving part and the Y-axis moving part, the horizontal position of the multi-head pressing unit 11 at the bottom of the pressing head adjusting motor 59 is adjusted. Specifically, the X-axis moving component includes an X-axis rectangular moving assembly housing 58. The top center of the moving assembly housing 58 is connected to a hydraulic rod via a connecting column. A lead screw I clamping joint 61 is rotatably installed inside the moving assembly housing 58. One end of the lead screw I clamping joint 61 is connected to a moving servo motor I 49 fixed inside the moving assembly housing 58 via a coupling, and the other end is supported and positioned inside the moving assembly housing 58 via a positioning sleeve 54. A nut I 52 is threaded onto the lead screw I clamping joint 61, and the nut I 52 is provided with a guide for limiting its rotation. The device, namely, drives the lead screw I clamp joint 61 to rotate by starting the mobile servo motor I49, thereby controlling the nut I52 to move along the lead screw I clamp joint 61. At the same time, the bottom of the nut I52 is fixed to the Y-direction moving part through the sliding connecting rod. Meanwhile, the bottom wall of the moving component housing 58 in the X-direction moving part corresponding to the sliding connecting rod is provided with a slide rail for the movement of the sliding connecting rod. That is, under the action of the mobile servo motor I49, the lead screw I clamp joint 61, the nut I52, and the sliding connecting rod, the X-direction position of the Y-direction moving part is adjusted. The Y-axis moving component includes a Y-axis rectangular moving component housing 58. Inside the moving component housing 58, a lead screw II 53 rotates. One end of the lead screw II 53 is connected to a moving servo motor II 50 via a coupling. A nut II is threaded onto the lead screw II 53. The moving servo motor II 50, lead screw II 53, and nut II operate on the same principle as the moving servo motor I 49, lead screw I clamp 61, and nut I 52 in the X-axis moving component. That is, by starting the moving servo motor II 50, the lead screw II 53 is driven to rotate, thereby controlling the nut II to move along the lead screw II 53. The bottom of the nut II is connected downward to the pressing head adjusting motor 59 via a sliding connecting rod, thereby realizing the X and Y upward position adjustment of the multi-head pressing unit 11. It should be noted that the transmission between the lead screw, nut, and motor in the X-axis and Y-axis moving parts is a conventional lead screw and nut transmission structure. That is, by adjusting the rotation direction of the motor, the nut can be controlled to move along the lead screw in both directions. The detailed structural design will not be elaborated here.

[0031] In a preferred embodiment of the present invention, to increase the stability of the Y-direction rectangular moving component housing 58 when moving along the X-direction, T-shaped grooves 55 are provided on both side walls of the X-direction rectangular moving component housing 58. A T-shaped slider 56 is slidably connected inside the T-shaped groove 55. The outside of the T-shaped slider 56 is connected to the top of the Y-direction rectangular moving component housing 58 through a fixed connecting rod 57. That is, by means of the X-direction movement of the T-shaped slider 56 in the T-shaped groove 55, the smoothness of the connection between the Y-direction rectangular moving component housing 58 and the X-direction rectangular moving component housing 58 is enhanced.

[0032] As a preferred embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 9 As shown, the multi-press head assembly includes a press head mounting base plate 60 fixed on the bottom output end of the press head adjusting motor 59. Multiple press heads are detachably mounted at equal intervals along the bottom of the press head mounting base plate 60. That is, by using the rotation of the press head adjusting motor 59 and the movement of the press head moving assembly 13 in the X and Y directions, the press heads at different positions can be adjusted to precisely press the brake calipers placed on the adjustable positioning unit 12 at different positions. The top of the pressing head is provided with 61, and the bottom of the pressing head mounting plate 60 corresponding to 61 has a locking hole. 61 is engaged with the locking hole to control the installation, removal and replacement of the pressing head. Preferably, the types of press-fitting heads include guide pin press-fitting heads, piston press-fitting heads, dust cover press-fitting heads, and silencer press-fitting heads for press-fitting components such as guide pins, pistons, dust covers, and silencer plates; The piston pressing head can be configured as a rotary pressing head 63 as needed. The top of the rotary pressing head 63 is connected to a rotary pressing motor 62. The rotary pressing motor 62 controls the rotation of the rotary pressing head 63. While controlling the rotary pressing head 63 to press the piston, the rotary pressing head 63 can be driven to rotate and fix the piston by the rotational power of the rotary pressing motor 62. By adjusting the rotation of the pressing head motor 59 and the precise movement of the pressing head moving assembly 13 in the X and Y directions, different pressing heads can be quickly switched to adapt to the pressing requirements of different parts on the brake caliper. This significantly reduces tool change time and improves pressing efficiency. At the same time, through the two-dimensional movement of the pressing head moving assembly 13 and the rotation of the pressing head adjusting motor 59, the multi-pressing head assembly can be arbitrarily adjusted in position and angle in the horizontal plane, so that the pressing head is always perpendicular to the pressing position of the brake caliper, reducing manual intervention and realizing a fully automated pressing process.

[0033] As a preferred embodiment of the present invention, such as Figures 3-8 As shown, the support adjustment assembly includes a set of open base plates 26. A connecting block 24 is provided at the opening of the open base plate 26. A servo motor I 20 is connected to the side of the connecting block 24 away from the center of the open base plate 26. The servo motor I 20 is mounted on the top of the side plate by a fixing plate. That is, the rotation of the servo motor I 20 drives the connecting block 24 to rotate. A fixing rod 29 is installed on one side of the connecting block 24 by an L-shaped connecting rod 25. A rotating sleeve rod 28 is fitted in the middle of the fixing rod 29. An inner support rod 27 slides through the rotating sleeve rod 28. One end of the inner support rod 27 is fixedly connected to the inside of the open base plate 26, and the other end is rotatably connected to the inside of the rotating sleeve rod 28. A servo motor III is fixedly installed at the end of the fixing rod 29 away from the rotating sleeve rod 28. 22. Servo motor III 22 is distributed parallel to the inner support rod 27. A drive gear 31 is installed on the output shaft end of servo motor III 22. A driven gear 30 is fixedly installed on the inner support rod 27 and meshes with one side of the drive gear 31. By starting servo motor III 22, the drive gear 31 is driven to rotate, which in turn drives the driven gear 30 to control the rotation of the inner support rod 27. At the same time, one end of the inner support rod 27 is fixedly connected to the inner wall of the open base plate 26. At this time, the open base plate 26 can be driven to swing around the inner support rod 27 (rotation direction two). Under the connection of L-shaped connecting rod 25, rotating sleeve rod 28, and fixed rod 29, when servo motor I 20 controls the connecting block 24 to rotate, the open base plate 26 can be driven to rotate around the connecting block 24 synchronously (rotation direction one). An external gear ring 36 is provided on the outer wall of the open base plate 26. A drive tooth 37 is engaged on one side of the external gear ring 36. A servo motor II 21 is connected to the bottom center of the drive tooth 37. Two sets of swing positioning components are symmetrically arranged between the bottom of the servo motor II 21 and the top of the drive tooth 37. The swing positioning components are used to keep the servo motor II 21 and the drive tooth 37 in stable rotation along the external gear ring 36 on the outside of the open base plate 26 (rotation direction three). At the same time, an L-shaped mounting plate 35 extending to the top center of the open base plate 26 is installed on the top of the upper swing positioning component. The top of the L-shaped mounting plate 35 is detachably connected to the hydraulic clamping assembly 14. That is, under the operation of rotation direction one, two, and three, the brake caliper positioned on the hydraulic clamping assembly 14 can be adjusted in any angle direction. This ensures that the brake caliper in the clamping state can be adjusted in the placement angle without disassembly, ensuring that any position to be pressed on it can accurately correspond to the multi-pressing head assembly above. This solves the problem of frequent disassembly and repositioning required by traditional clamps. Meanwhile, by adopting structures such as open base plate 26, external gear ring 36, drive gear 37, limit slide groove 32, and limit slider 33, the stability and accuracy of the adjustment process are ensured. The connection between L-shaped mounting plate 35 and hydraulic clamping assembly 14 is simple and reliable, ensuring that the brake caliper will not shift or vibrate during the adjustment process, thus improving the safety of press fitting. The swing positioning component includes a guide rod fixed to the bottom of the servo motor II 21 and the top of the positioning sleeve rod 38. Each guide rod is fitted with a collar. A positioning sleeve rod 38 is connected to one side of the upper collar. The bottom of the positioning sleeve rod 38 is fixed to the servo motor II 21. An L-shaped limiting link 34 is installed on the side of the upper and lower collars facing the center of the open base plate 26. A limiting slider 33 is installed on the side of the L-shaped limiting link 34 facing the upper and lower side walls of the open base plate 26. A limiting groove 32 is opened on the upper and lower side walls of the open base plate 26 corresponding to the limiting slider 33. The limiting slider 33 slides along the inside of the limiting groove 32, thereby restricting the servo motor II 21, drive gear 37 and other structures to the outside of the open base plate 26 and controlling the meshing of the drive gear 37 with the outer gear ring 36. Controlling the limiting slider 33 to slide along the inside of the limiting groove 32, thereby realizing the rotation of the L-shaped mounting plate 35 around the center of the open base plate 26, and thus realizing the rotation control of the hydraulic clamping assembly 14. Compared to existing technologies, the support adjustment component enables automated adjustment of the brake caliper angle, significantly reducing workstation adjustment time. It is suitable for production lines with multiple varieties and small batches, improving the flexibility and production efficiency of the entire assembly line.

[0034] The hydraulic clamping assembly 14 includes a hydraulic cylinder base 39 detachably connected to the top of an L-shaped mounting plate 35. An auxiliary clamping hydraulic cylinder 23 is installed inside the hydraulic cylinder base 39. A rectangular-opening clamping frame 40 is fixedly installed on the side of the hydraulic cylinder base 39 facing the output end of the auxiliary clamping hydraulic cylinder 23. Two sets of relatively movable secondary clamping plates are symmetrically arranged at the opening of the clamping frame 40. The secondary clamping plates can adapt to different positions of the brake caliper, ensuring clamping stability. A side-mounted telescopic rod 42 is installed at the end of the secondary clamping plate located at the opening of the clamping frame 40. A telescopic rod hole plate 44 fixed to the side wall of the clamping frame 40 is telescopically fitted inside the clamping frame 40 corresponding to the side-mounted telescopic rod 42. A lower swing rod 47 is rotatably connected to the bottom of the side-mounted telescopic rod 42 facing the middle of the opening of the clamping frame 40 via a swing shaft. The end of the lower swing rod 47 away from the side telescopic rod 42 is rotatably connected to the swing rod sleeve 45 through the swing shaft. A front and rear swing rod 41 is fitted together between the two swing rod sleeves 45. The middle side of the front and rear swing rod 41 is fixedly connected to the output end of the auxiliary clamping hydraulic cylinder 23. At the same time, the top of the two swing rod sleeves 45 is oscillatingly connected to the top side of the clamping frame 40 through the swing shaft and the upper swing rod 46. By starting the auxiliary clamping hydraulic cylinder 23, the front and rear swing rods 41 are controlled to move back and forth, thereby driving the two swing rod sleeves 45 to slide on the front and rear swing rods 41. Then, in conjunction with the upper swing rod 46 and the lower swing rod 47 on the upper and lower sides of the swing rod sleeve 45, the swing rods 46 and 47 on the upper and lower sides of the swing rod sleeve 45 are respectively oscillating with the clamping frame 40 and the side telescopic rod 42, thereby controlling the side telescopic rod 42 to move horizontally along the telescopic rod hole plate 44, thereby driving the two secondary clamping plates to move relative to each other, and clamping and fixing the brake caliper. Specifically, the secondary clamping plate includes a straight clamping plate 48 fixedly installed at the outer end of the side telescopic rod 42. The straight clamping plate 48 is distributed perpendicular to the side telescopic rod 42 and is used to clamp brake calipers at some planar regular shapes. The end of the straight clamping plate 48 extends outward and is equipped with an arc-shaped clamping block 43 through an L-shaped connecting rod. The arc-shaped clamping block 43 is used to clamp brake caliper positions at some irregular positions. It should be noted that, since the straight clamping plate 48 and the arc-shaped clamping block 43 are in synchronous motion at all times during operation, the two cooperate with each other to clamp and fix the brake caliper, thus fully improving the positioning strength.

[0035] That is, the hydraulic clamping assembly 14 adopts a two-stage clamping plate design. The auxiliary clamping hydraulic cylinder 23 drives the front and rear swing rods 41 and the swing mechanism, so that the clamping plate can adapt to different shapes and positions of the brake caliper (such as regular planes or irregular curved surfaces), ensuring uniform distribution of clamping force and preventing the brake caliper from moving or deforming during the pressing process. Furthermore, based on hydraulic transmission, the clamping action responds quickly, and the clamping and releasing processes are highly automated, reducing manual operation time.

[0036] As a preferred embodiment of the present invention, the hydraulic cylinder base 39 and the L-shaped mounting plate 35 are connected by various installation methods, such as threaded connection, snap-fit ​​connection, embedded connection, etc. The specific installation method depends on the actual situation and is not limited here.

[0037] The working principle of this invention is as follows: During idle periods in this device, all the aforementioned driving components (representing power elements, electrical devices, and compatible power supplies) are connected via wires. The electrical connections are completed in sequence between the working components. The detailed connection methods are well-known in the art. The following mainly describes the working principle and process, without further explanation of the electrical control. Place the brake caliper on the hydraulic clamping assembly 14 of the adjustable positioning unit 12, start the auxiliary clamping hydraulic cylinder 23, and use the secondary clamping plate (straight clamping plate 48 and arc-shaped clamping block 43) to adaptively clamp the brake caliper. According to the position of the part to be pressed on the brake caliper, control the servo motor I 20, servo motor II 21 and servo motor III 22 in the support adjustment assembly to adjust the three-dimensional angle of the open base plate 26, drive the hydraulic clamping assembly 14 and the brake caliper to rotate, so that the position to be pressed is vertically aligned with the pressing head of the multi-head pressing unit 11. The main lifting hydraulic cylinder 16 of the pressing and lifting unit is activated, driving the lifting base plate 17 and the multi-head pressing unit 11 to descend to an appropriate height. At the same time, the pressing head moving assembly 13 drives the lead screw mechanism through the moving servo motor I 49 and the moving servo motor II 50 to adjust the position of the pressing head in the X and Y directions. The pressing head adjusting motor 59 rotates the pressing head mounting base plate 60 to select the required pressing head (such as the guide pin pressing head or the rotary pressing head 63). The pressing head presses the brake caliper components; if rotational pressing is required (such as for pistons), the rotary pressing motor 62 is started, and the rotary pressing head 63 is controlled to rotate and fix it while pressing. After pressing is completed, the main lifting pressing hydraulic cylinder 16 lifts the multi-head pressing unit 11, the auxiliary clamping hydraulic cylinder 23 releases the brake caliper, the workpiece is taken out, and the device is reset for the next use.

[0038] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown.
