Description

Technical Field

[0001] This utility model belongs to the field of automotive repair technology, and in particular relates to a tooling vehicle for a window regulator assembly. Background Technology

[0002] In the automotive assembly process, the power window regulator, as a core component of the door system, directly affects the window's sealing performance, smoothness of operation, and service life. As the automotive industry shifts towards flexible production across multiple platforms and models, the structural dimensions of power window regulators are becoming increasingly diverse due to vehicle model differences, highlighting the growing inadequacy of traditional tooling equipment in terms of versatility.

[0003] Traditional window regulator installation fixtures typically employ fixed clamps and manual screw adjustments, only compatible with a single type of regulator. Changing vehicle models necessitates complete disassembly and fixture replacement, severely hindering production line speed. Another type of adjustable fixture, while incorporating sliding guides, still relies on manual measurement with a tape measure and wrench tightening for height adjustment, resulting in significant accuracy errors and prolonged time spent aligning the regulator with the door mounting holes.

[0004] To address these issues, we provide a window regulator assembly tooling vehicle. Utility Model Content

[0005] The purpose of this utility model is to provide a glass regulator assembly tooling cart, which solves the problems of existing tooling carts being unable to efficiently and quickly clamp glass regulator assemblies of different sizes and unable to achieve automated assembly height adjustment by cooperating with clamping components and assembly height adjustment components.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a tooling vehicle for a glass lifter assembly, comprising a frame. An assembly height adjustment component is fixedly connected to the top of the frame. A clamping component is threadedly connected to the surface of the assembly height adjustment component. The assembly height adjustment component includes a drive motor fixedly connected to the top of the frame. A driving bevel gear is fixedly connected to the output shaft of the drive motor. A driven bevel gear meshes with the surface of the driving bevel gear. A lead screw is fixedly connected to the bottom of the driven bevel gear. The bottom of the lead screw is fixedly connected to the inner wall of the frame via a bearing. Distance measuring transmitters are fixedly connected to both sides of the bottom of the frame's inner cavity. The clamping component includes a threaded block threadedly connected to the lead screw. A mounting plate is fixedly connected to the surface of the threaded block. A fixing plate is fixedly connected to the bottom of the mounting plate. An electric push rod is fixedly connected to the top of the mounting plate. A clamping plate is fixedly connected to the output end of the electric push rod. Pressure sensors are fixedly connected to opposite sides of the fixing plate and the clamping plate.

[0008] The present invention is further configured such that omnidirectional wheels are fixedly connected to the four corners of the bottom of the frame, and a brake pad is provided on one side of the omnidirectional wheel. The omnidirectional wheel with the brake pad supports the tooling cart to move freely 360° and be precisely positioned, adapting to the complex ground environment of the workshop, and a single person can push it to complete the workstation change.

[0009] The present invention is further configured such that a sliding groove for moving the threaded block is provided on the surface of the frame, and a controller is fixedly connected to the back of the frame. The sliding groove guides the threaded block to move vertically, and the controller supports switching between manual and automatic modes.

[0010] The present invention is further provided that a protective cover is fixedly connected to the top of the frame, and the protective cover is fitted onto the surface of the drive motor to prevent dust and oil from entering the drive motor.

[0011] The present invention is further configured such that the assembly height adjustment component also includes a ranging receiver fixedly connected to both sides of the bottom of the threaded block. The ranging receiver and the ranging transmitter calculate the height of the clamping component in real time, providing accurate feedback signals for height adjustment.

[0012] The present invention is further configured such that limit grooves are provided on both sides of the surface of the mounting plate, and limit blocks are slidably connected to the inner cavity of the limit grooves. One side of the limit block is fixedly connected to the surface of the clamping plate. The limit grooves and limit blocks cooperate to limit the lateral displacement of the clamping plate, ensuring that the lifting device remains horizontal during the clamping process and improving the hole alignment accuracy.

[0013] The present invention is further configured such that rubber pads are fixedly connected to the opposite sides of the fixing plate and the clamping plate, and the surface of the rubber pads is provided with through holes for pressure sensors. Anti-slip textures are provided on the surface of the rubber pads to increase the coefficient of friction. In conjunction with the closed-loop control of the pressure sensor, non-destructive clamping of parts made of different materials such as plastic and aluminum alloy can be achieved.

[0014] The present invention is further configured such that the bottom of the lead screw is fixedly connected to the inner wall of the sliding groove through a bearing, and the inner cavity of the threaded block is provided with a threaded hole for use with the lead screw. The lead screw is integrated with the inner wall of the sliding groove through the bearing, which reduces radial runout during transmission and ensures the stability of height adjustment.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model uses an electric push rod to drive a clamping plate that works in conjunction with a fixing plate. Combined with a pressure sensor that provides real-time feedback on the clamping force, it can automatically adapt to different sizes of window regulator assemblies. It can achieve rapid positioning by adjusting the stroke of the electric push rod without changing the clamps. The rubber pad prevents scratches on the surface of the parts while applying clamping force. It is especially suitable for the precision clamping of lightweight aluminum alloy window regulators, reducing the damage rate of parts caused by improper clamping.

[0017] 2. The laser ranging system composed of the ranging transmitter and receiver of this utility model can automatically detect the height of the mounting plate, so as to adapt it to the assembly height of different models of window regulator assemblies. The drive motor drives the lead screw through the bevel gear set to realize the precise lifting and lowering of the clamping component driven by the threaded block. Compared with the error of traditional manual tape measure measurement, this system can significantly adapt to the rapid response requirements of multi-model mixed production line production by reducing the installation height deviation of the regulator.

[0029] Example 2

[0030] Please see Figure 1-5 Based on Embodiment 1, universal wheels are fixedly connected to the four corners of the bottom of the frame 1, and a brake pad is provided on one side of the universal wheel. The surface of the frame 1 is provided with a sliding groove 26 for the threaded block 31 to move. The back of the frame 1 is fixedly connected to a controller 4. The top of the frame 1 is fixedly connected to a protective cover 27, and the protective cover 27 is fitted onto the surface of the drive motor 21. The assembly height adjustment assembly 2 also includes a distance measuring receiver 28 fixedly connected to both sides of the bottom of the threaded block 31.

[0031] Specifically: the casters with brake pads support 360° free movement and precise positioning of the tooling cart, adapting to complex workshop floor environments, allowing a single person to push it to complete workstation changes; the sliding groove 26 guides the threaded block 31 to rise and fall vertically; the controller 4 supports manual and automatic mode switching; the protective cover 27 prevents dust and oil from entering the drive motor 21; the ranging receiver 28 and the ranging transmitter 25 calculate the height of the clamping assembly 3 in real time, providing accurate feedback signals for height adjustment; the limit groove 37 cooperates with the limit block to limit the lateral displacement of the clamping plate 35, ensuring that the lifter remains horizontal during clamping and improving the hole alignment accuracy; the rubber pad surface has anti-slip textures to increase the friction coefficient, and in conjunction with the pressure sensor 36 closed-loop control, it can achieve non-destructive clamping of parts made of different materials such as plastic and aluminum alloy; the lead screw 24 is integrated with the inner wall of the sliding groove 26 through the bearing design, reducing radial runout during transmission and ensuring the smoothness of height adjustment.

[0032] The working principle of this utility model is as follows: the window regulator assembly is placed between the fixed plate 33 and the clamping plate 35. The electric push rod 34 is activated and pushes the clamping plate 35 to move. The pressure sensor 36 monitors the clamping force in real time until it reaches the preset value. The limit block slides in the limit groove 37 to ensure that the clamping plate 35 moves parallel and prevents the regulator from tilting. The controller 4 selects the corresponding vehicle model and retrieves the preset regulator size parameters. The distance measuring transmitter 25 and the distance measuring receiver 28 cooperate to calculate the vertical distance of the clamping assembly 3. At the same time, the drive motor 21 drives the active bevel gear 22. Rotation causes the active bevel gear 22 to drive the driven bevel gear 23 and the lead screw 24 to rotate. The threaded block 31 moves up and down along the sliding groove 26 until the distance measuring system reports a height error of <0.5mm, at which point it stops. At this point, the height of the clamping component 3 is the installation height of the window regulator assembly. The tooling cart is manually pushed close to the car door. Using the height and horizontal positioning of the clamping component 3, the mounting hole of the regulator is precisely aligned with the screw hole of the car door to complete the bolt fixing. When disassembling, the electric push rod 34 moves in the opposite direction to release the clamping force, and the drive motor 21 reverses to reset the clamping component 3 and enter the next cycle.
