Description

Tow / Camber Automated Processing Equipment for Coupled Torsion Beam Axle for Automobile

The present invention provides a new type of coupled torsion beam axle that can more effectively process the toe and camber required on both sides of the coupled torsion beam axle installed at the rear of the vehicle. It relates to an automated processing apparatus that can be used exclusively for CTBA).

In general, a coupled torsion beam axle (CTBA) for automobiles has a low production cost due to a simple component configuration, although the design performance range such as ride comfort and maneuvering stability is not high compared to a suspension system of an independent suspension system. Due to its low weight and weight, it has been applied mainly to the rear suspension of light and medium and small vehicles. Hereinafter, for convenience, referred to as the workpiece (A).

Although the workpiece A has been designed and manufactured in various ways so far, a tubular torsion beam 10 having a constant length is configured as shown in the drawing, and the left and right sides of the tubular torsion beam 10 are formed. A pair of trailing arms 20 are interconnected by a tubular torsion beam 10, the front end of the trailing arm 2 mounted bush sleeve 30 with a rubber bush pivotally coupled to the vehicle body. The inside of the rear end of the trailing arm 20 is configured with a spring seat 40 to which the suspension spring is mounted and a damper bracket 50 to which the shock absorber is mounted, and the trailing arm 2 is installed. Outside the rear end of the) is provided with a wheel carrier 60 and the spindle plate 70 for coupling the rear wheel of the vehicle.

As a result, the coupled torsion beam axle (CTBA) for a vehicle, that is, the workpiece A, has a tubular torsion beam 10, a trailing arm 20, a bushing sleeve 30, a spring seat 40, and a damper bracket 50. ), The wheel carrier 60 and the spindle plate 70 are configured.

On the other hand, the spindle plate 70 of one surface of the wheel carrier 60, which is configured on each of the left and right sides of the workpiece A, has a tow (alignment of the wheels of the vehicle, based on the centerline of both wheels when viewed from above). It is essential that the machining be done to ensure the proper difference between the length of the front and rear parts of the tire, the toe) and the camber (the difference between the length of the top and bottom parts, and the camber, based on the centerline of both wheels when viewed from the front of the car's wheels). Required.

At this time, the tow-camber processing is a workpiece and a heavy-body coupled torsion beam axle (CTBA) is fixed to the clamp plate or the like, and then the spindle plate 70 of one surface of the wheel carrier 60, respectively configured on the left and right sides ) Can be made from a variety of machining operations to correspond to the desired toe and camber angular conditions so as to precisely perform the surface treatment (machining to cut the surface).

However, the conventional tow-camber processing and the apparatus for the same carried out on a coupled torsion beam axle (CTBA) for automobiles,

Seated and clamped Automotive Coupled Torsion Beam Axle (CTBA), which is bulky, heavy and combined with various components, is pressed down on the top of the jig according to the size of the frame and cylinder movement. Complex structure including a clamp system, etc. to fix the installation is installed, but inevitably upwards,

When chamfering the spindle plate 70 on one side of the wheel carrier 60 according to the angle conditions of the toe and camber, the direction in which the chamfering tool moves is limited to the method of passing back and forth. Because there is not,

The working distance of the tool required for processing is long, accompanied by unnecessary friction, which causes a lot of processing time, and also causes a large increase in the wear rate of the tool.

Furthermore, the conventional equipment is required to directly process the material from the jig provided in the tow and camber processing equipment when the workpiece requiring processing is placed on the jig and loaded, or when the unloaded workpiece is separated from the jig. Because it is picking up and loading or unloading,

The process of loading or unloading a coupled, torsional beam axle (CTBA) for automobiles, which is bulky, heavy and complex, combined with various components, is very difficult and very precise. Not only is it easy to clamp reliably,

In addition, the process of replacing the tool due to interference, etc., is inconvenient, and the weight and volume, as well as the process and cost of design and manufacturing, are also very expensive.

Furthermore, the conventional equipment is composed of a fixed jig made to fit the work of a particular model, the work of the other model of the workpiece of the other models having a difference in shape and size, etc. Automotive coupled torsion beam axle (CTBA) When you want to process

Since the weight and ultra-high processing equipment designed and manufactured for the model must be purchased and prepared separately,

In order to freely process various types and models of coupled torsion beam axles (CTBA) for automobiles, there are significant problems such as enormous cost and installation space.

Therefore, the present invention considers the shape and structural characteristics of the workpiece (A), which is a coupled torsion beam for automobiles, during tow and camber processing, and presents the optimum setting conditions (fixing and clamping) for quick, simple and precise machining. In order to maximize the efficiency, it is possible to make effective processing by the shortest time and simple operation as well as the simple and detachable operation for various models. Its main purpose is to provide a new concept of automotive tow and camber automated processing equipment for coupled torsion beam axles, which are more efficient.

The present invention for achieving the above technical problem is a milling machine 200 for tow-camber processing on the spindle plate 70 of one side of the wheel carrier 60 configured on the workpiece (A) on the left and right of the base plate 100 Installing each in a state where a constant distance from each other is maintained; Between the said tow-camber milling machine 200, the trailing arm receiving means 310 which can support the bottom part of the trailing arm 20 with the said left and right wheel carriers 60, and the said spring Spring seat support means 320 that can support the bottom of the seat 40, Bush sleeve automatic clamping device 330 that can hold the bushing sleeve 30 formed therein through the hole 31, and A work piece setting jig device 300 provided with wheel carrier push type clamp means 340 for pressing the upper portion of the spindle plate 70; On the bottom surface of the workpiece setting jig device 300, one or more jig body support 400 is installed to be supported by a predetermined height, but the workpiece setting jig device 300 and the jig body support 400 are installed. Between) is provided with a detachable means 500 and pick-up means 600 to enable easy replacement with the jig device 300 for the workpiece setting of the other model as needed.

As described above, the tow-camber automated processing apparatus for automotive coupled torsion beam axles of the present invention is excellent in safety when clamping a workpiece-oriented coupled torsion beam axle (CTBA) to a jig device. It is not only possible to settle in a secluded state, which shows the characteristics of openness (it is a structure that is totally open, which is very easy to settle and take out workpieces), and it is possible to set up more quickly, simply and precisely. In order to minimize the wasted time and manpower, and to chamfer the tow and camber on both sides of the CTBA, the tool moves more effectively. This greatly reduces machining time, eases tool exchange, and reduces wear rate of tool carbide tips. Of course, it is a useful invention, such as expecting enormous cost savings effect, because the workpiece can be processed in a single equipment by changing the jig device only different models.
