Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass lifter assembly technology, specifically to an assembly and fixing fixture for an electric glass lifter. Background Technology
[0002] Electric window regulators are commonly used as the control devices for raising and lowering car windows and are an important component of vehicles. An electric window regulator typically consists of an operating mechanism (rocker arm or electric control system), a transmission mechanism (gear, rack, or pinion gear, or gear-coupling mechanism), a window raising mechanism (raising arm, moving bracket), a window support mechanism (window bracket), and stop springs, balance springs, etc., making it a complex structure with numerous parts.
[0003] Because the power window regulators for the left and right windows are symmetrical, existing systems assemble them on a single fixture, making it difficult for new employees to identify and causing confusion. This poses a safety hazard, resulting in low production efficiency and low output. Furthermore, the assembly process primarily involves manually pressing down the springs to insert the product, which is time-consuming and labor-intensive, and makes subsequent processes like line installation and wiring difficult. Therefore, there is an urgent need for a new type of assembly fixture for power window regulators. Utility Model Content
[0004] This utility model aims to solve the technical problems existing in the prior art, and innovatively proposes an assembly and fixing fixture for electric window lifters. It has a simple structure, stable operation, is easy to learn and use.
[0005] To achieve the above objectives, this utility model provides an assembly and fixing fixture for an electric window regulator, including a worktable. The worktable is provided with a contour-following limiting structure for engaging a cable reel seat. The left and right sides of the contour-following limiting structure are provided with a left push assembly and a right push assembly for compressing the springs on the left and right sides of the cable reel seat. The left and right sides of the contour-following limiting structure are provided with clearance notches for making way for the springs and cables. The left push assembly includes a left push cylinder and a left pressure plate, and the right push assembly includes a right push cylinder and a right pressure plate. Both the left and right pressure plates are provided with slots for engaging the cable sleeve.
[0006] In the above scheme: the extended ends of the left and right propulsion cylinders are both inclined forward, the rear ends of the left and right pressure plates both extend beyond the extended ends, and the slot is set on the part of the left or right pressure plate that extends beyond the extended ends, which is a reasonable arrangement.
[0007] In the above scheme, the card slot is set at the top of the left or right pressure plate, so it is inserted from top to bottom, which is more convenient than inserting from the side.
[0008] In the above solution: the diameter of the slot is smaller than the diameter of the spring to prevent the spring from coming out of the slot and to ensure the spring's clamping effect.
[0009] In the above scheme: the contour-following limiting structure includes multiple limiting blocks arranged around the winding seat.
[0010] In the above solution: the limiting block, the left push cylinder and the right push cylinder can all be detachably installed on the worktable, and can be adjusted according to different electric window lifters, making it widely applicable.
[0011] In summary, the beneficial effects of this utility model are: It has a simple structure; the contour-following limiting structure can limit the winding seat, facilitating subsequent spring compression. The cylinders and pressure plates on both sides can compress the spring without manual spring compression, saving manpower, improving work efficiency, and simplifying assembly. The slots on both sides can fix the cables on both sides, preventing incorrect installation and facilitating subsequent winding. Furthermore, the cylinder compression of the spring provides stable force, preventing the spring from popping out. Operation is stable, easy to learn, and quick to master. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the present invention in use.
[0013] Figure 2 This is a schematic diagram of the present invention. Detailed Implementation
[0014] The present invention will be further described below with reference to embodiments and accompanying drawings:
[0015] like Figures 1-2 As shown, an assembly and fixing fixture for an electric window regulator includes a worktable 1 with a contour-following limiting structure for engaging a cable reel 6. In this embodiment, the contour-following limiting structure includes multiple limiting blocks 2 arranged around the cable reel 6.
[0016] The left and right sides of the contour limiting structure are provided with left and right push components for compressing the springs 5 on the left and right sides of the winding seat 6, and the left and right sides of the contour limiting structure are provided with clearance notches for making way for the springs and cables.
[0017] The left propulsion assembly includes a left propulsion cylinder 7 and a left pressure plate 8, while the right propulsion assembly includes a right propulsion cylinder 4 and a right pressure plate 3. The extended ends of both the left and right propulsion cylinders are angled forward. The rear ends of both the left and right pressure plates extend beyond their extended ends. Both the left and right pressure plates have slots a for the cable sleeve to engage, and these slots a are positioned on the extended ends of either the left or right pressure plate 8 or 3, a reasonable arrangement. Since slot a is located near the top of the left or right pressure plate 8 or 3, engagement is from top to bottom, which is more convenient than engagement from the side. The diameter of slot a is smaller than the diameter of the spring 5 to prevent the spring 5 from dislodging from slot a, ensuring the spring 5's clamping effect.
[0018] Limit block 2, left push cylinder 7 and right push cylinder 4 can all be detachably installed on worktable 1, and can be adjusted according to different electric window lifters, making it widely applicable.
[0019] In use, first place the winding seat 6 of the electric window regulator within the area enclosed by the limiting block 2. Then, insert the two pull cables 9 and spring 5 of the window regulator through the process groove of the winding seat 6. Simultaneously, insert the sleeves of the pull cables 9 into the slots a on the left and right pressure plates on both sides. The left push cylinder 7 and the right push cylinder 4 are also equipped with self-locking pneumatic pedals. When the self-locking pneumatic pedals are activated, and air is supplied in the pushing direction of the left and right push cylinders 7 and 4, the two cylinders simultaneously push the left and right pressure plates, compressing the assembled spring 5 to its minimum size for convenient subsequent production assembly. After the steel wire of the pull cable 9 is wound onto the winding reel, insert the winding reel into the winding seat 6, activate the self-locking pneumatic pedal again, release the left and right pressure plates, and remove the workpiece to complete the operation. The subsequent wire hanging process can be completed together with the wire winding process, eliminating the need for wire hanging fixtures and reducing the need for separate wire loading and hanging processes.
