Abstract
Description
Technical Field
[0001] This utility model relates to the field of steering gear housing processing, specifically a multi-station machining fixture for steering gear housings. Background Technology
[0002] The steering gear is the core component of the car steering system. Its function is to convert the rotational torque applied by the driver to the steering wheel into linear or oscillating motion, thereby driving the steering rocker arm or steering rack to achieve wheel steering. The steering gear housing is a key structural component of the steering gear. As the mounting base for various components of the steering system, it not only needs to withstand complex mechanical loads, but also needs to ensure sealing, durability and precision.
[0003] Traditional fixtures typically have an independent pneumatic or hydraulic cylinder for each station. Clamping and releasing must be executed sequentially through control (such as PLC programming). In multi-station machining, there is a time difference between the actions of each station, which leads to an extension of the overall machining cycle. For example, if each action of a 4-station fixture takes 2 seconds, the total cycle may reach 8 seconds. Synchronous drive can compress the time to 2 seconds. After releasing the current workpiece, asynchronous fixtures must wait for all stations to complete their actions before loading and unloading, and cannot take advantage of the idle time when some stations have already released the workpiece to perform operations in advance. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, traditional fixtures typically use independent cylinders or hydraulic cylinders for each workstation. Clamping and releasing must be performed sequentially through control. During multi-station processing, there are time differences in the actions of each workstation, which leads to problems such as extended overall processing cycle. This utility model proposes a multi-station processing fixture for steering gear housings.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a multi-station machining fixture for steering gear housing, including a base, a first bearing fixedly connected to the inner cavity of the base, a connecting column fixedly connected to the inner wall of the inner ring of the first bearing, a rotating disk fixedly connected to one end of the connecting column, a machining disk fixedly connected to the surface of the rotating disk, and a plurality of machining disks, each machining disk having a clamping mechanism on one side.
[0006] The clamping mechanism includes a second bearing, the outer ring of which is fixedly connected to the inner cavity of the processing disk. A rotating shaft is fixedly connected to the inner wall of the inner ring of the second bearing. A placement disk is fixedly connected to one end of the rotating shaft. A guide groove is provided on one side of the placement disk. A slide rail is fixedly connected to one side of the processing disk. A limit block is slidably connected to the surface of the slide rail. A connecting rod is fixedly connected to one side of the limit block. The surface of the connecting rod is slidably connected to the inner wall of the guide groove. A clamping rod is fixedly connected to one end of the connecting rod.
[0007] Preferably, a limiting ring is fixedly connected to one side of the processing disk, the inner cavity of the limiting ring is slidably sleeved on the surface of the rotating shaft, a limiting rod is fixedly connected to the surface of the limiting ring, and the surface of the limiting rod is slidably connected to the inner cavity of the limiting block.
[0008] Preferably, a first gear is fixedly connected to the other end of the rotating shaft, a first motor is fixedly connected to one side of the processing disk, and the output end of the first motor is fixedly connected to one side of the first gear.
[0009] Preferably, a connecting ring is fixedly connected to one side of the rotating disk, and a second gear is slidably sleeved on the surface of the connecting ring, with the teeth of the second gear meshing with the teeth of the first gear.
[0010] Preferably, one end of the connecting column is fixedly connected to a transmission component, and one side of the transmission component is provided with four slots.
[0011] Preferably, a rotating component is rotatably connected to the bottom of the base, and a lever is fixedly connected to one side of the rotating component. The surface of the lever cooperates with four lever slots.
[0012] Preferably, a second motor is fixedly installed on one side of the base, and the output end of the second motor is fixedly connected to one side of the rotating component.
[0013] The advantages of this utility model are:
[0014] This invention enables multiple sets of first gears to rotate synchronously through the transmission of the second gear. The rotation of the first gear drives the rotation shaft to rotate, and the rotation shaft rotates along the second bearing inside the processing disk. When the rotation shaft rotates, it drives the placement disk to rotate. When the placement disk rotates, it can transmit multiple connecting rods and clamping rods through the guide groove to simultaneously clamp inward or release the steering gear housing outward. This solves the problems of traditional fixtures, which usually have independent cylinders or hydraulic cylinders for each station, requiring sequential control for clamping and releasing, and time differences in the actions of each station during multi-station processing, leading to an extended overall processing cycle.

The first motor 10 can be regarded as the driving source of the clamping mechanism 6. Multiple first gears 9 are meshed with the second gear 12.

[0028] Working principle: The base 1 provides the main support. The connecting column 3, which is connected to the rotating disk 4, can rotate along the first bearing 2 inside the base 1.

The rotating shaft 602 can rotate along the second bearing 601 inside the processing disk 5. When the rotating shaft 602 rotates, it can drive the placement disk 603 to rotate. When the placement disk 603 rotates, it can drive multiple connecting rods 607 and clamping rods 608 through the guide groove 604 to clamp inward or release the steering gear housing outward.
