Description

Technical Field

[0001] The utility model relates to a cutting tool, in particular to a composite motor housing sheath cutting tool. Background Art

[0002] As the name implies, tool sets are used to cover the outer circumference of products. Currently, tool sets on the market are mainly small-diameter and made of cemented carbide. They are widely used in the field of hole processing of mechanical parts. In production practice, when encountering the outer circle processing of large-diameter cylinders, lathe processing or milling processing by machining center milling cutter is generally adopted. However, when encountering some products that have high requirements for the coaxiality of the outer circle and cannot be completed on the lathe, such as motor housing processing, a composite tool set is needed, which can complete both the outer circle cylinder processing and the hole chamfering processing in one processing, thereby ensuring the accuracy requirements and processing rhythm requirements of the entire processing.

[0003] For large diameter outer circle processing, lathes or milling cutters in machining centers are generally used.

[0004] Lathe processing is nothing more than a more efficient processing method for peripheral circle processing. However, it cannot be used for lathe processing due to factors such as product structure and the inability of lathe clamping. Or in the case of lathe clamping processing, extremely complex auxiliary tooling is required, which makes its production cost high and is not suitable for large-scale promotion and application.

[0005] The outer circle of the workpiece is processed by the milling cutter of the machining center, which is also a common outer circle processing method. This method is relatively simple for small diameter processing and can be completed with a milling cutter. However, for large diameter outer circle processing, the processing time will be very long and the processing efficiency is not high, which is not conducive to promotion. At the same time, the milling cutter milling processing is linked to the X / Y axis of the machining center for each milling process. Relatively speaking, the processing accuracy is poor. For example, products with high requirements need to be divided into rough processing and static processing, and the processing time is too long. Commonly used lathe turning outer circle processing and milling cutter milling processing can only complete the processing of one processing part. For example, when the product hole needs chamfering, it cannot be completed at one time and needs to be completed with multiple tools.

[0006] In the process of machining complex workpieces, such as motor housing products, there are many machining procedures. For example, the conventional BT40 machining center can only hold 24 tools. Machining a motor housing requires many tools. If the external cylindrical machining occupies too many tool positions, the product cannot be processed effectively.

[0007] Therefore, developing a composite motor housing cutter set has become a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0008] The utility model provides a composite motor shell cutter sleeve in order to solve the above-mentioned drawbacks.

[0009] The above-mentioned purpose of the utility model is achieved through the following technical scheme: a composite motor casing cutter, including a spindle connecting handle, the spindle connecting handle is connected to a bridge plate, one end of the bridge plate is equipped with a sleeve boring unit, the sleeve boring unit is an outer circle boring mechanism; the other end is equipped with a chamfering unit, the chamfering unit is an inner hole chamfering mechanism.

[0010] Furthermore, the boring unit is provided with a boring unit blade seat, the boring unit blade seat is provided with a boring blade placement groove, and the boring blade is installed thereon.

[0011] Furthermore, the chamfering unit is provided with a chamfering blade placement groove, and a chamfering blade is installed thereon.

[0012] Furthermore, a water cooling channel communicating with the spindle connecting handle and the bridge plate is provided inside, the water inlet of the water cooling channel is connected to the water outlet of the spindle inner cooling, and the water cooling channel is provided with two water outlets, which are respectively directed to the corresponding tool cutting positions located at the boring unit and the chamfering unit.

[0013] The advantages of the utility model compared with the prior art are: the utility model can process products of different materials by replacing the blade, realize large diameter outer circle processing and outer circle chamfering one-time processing and forming, thereby greatly improving the processing efficiency and processing accuracy. At the same time, different blade seats can be replaced according to the different sizes and different precisions of the products to achieve multi-specification high-precision processing, and different spindle connecting handles can be replaced to apply to different machine tools.

[0014] Specifically, it says:

[0015] 1. Conventional milling cutters cannot process relatively deep outer circle sizes. Due to clamping reasons, the blade overhang is too long, which easily leads to increased tool runout and thus makes processing impossible. However, the boring cutter of the utility model can process larger diameters and deepen the outer circle sleeve boring process within the range of the spindle load.

[0016] 2. Efficiency advantage: Traditional boring cutters are made of carbide and are generally used to process small diameters. Traditional large diameter boring cutters require milling, which is slow, time-consuming and low-precision. The utility model can achieve large diameter outer circle, outer circle chamfering, high-precision and high-efficiency processing.

[0017] 3. Processing cost advantage: Conventional large-diameter external cylindrical processing requires multiple tools, and rough processing plus fine processing mode can ensure processing accuracy. It is necessary to purchase multiple milling cutters, which leads to higher prices; the utility model can replace multiple tools for processing.

[0018] 4. Processing precision advantage: boring and chamfering are integrated structures with good coaxiality, one-time processing and high precision. BRIEF DESCRIPTION OF THE DRAWINGS
