[New type of prior art] Accuracy: Product (2): In addition to the increase and enhancement of functions, the addition of 3, 二, 疋 疋 "an important basis for processing machinery, the processing accuracy of the products, the more stable the processing machinery In order to meet the recent miniaturization and the precision of the processing machine, in addition to the accuracy of the movement of the workpiece, the accuracy of the tool placed at the spindle is also an important determinant, and the accuracy of the tool spindle is Depending on the moving machine and its structural strength, take the tool spindle of an I-type machining machine as an example. As shown in the first figure, it is attached to the box (the front surface of the upper section of the Γ* column (10) is locked with a level. The extended spindle ( ) " sinusoidal head box (20) contains the housing part of the spindle mechanism in the fixed part (25) for locking the yoke against the column (10). The body raft (21) is horizontally extended, and only one end is connected to the fixing portion (25 body) and is affected by the weight and gravity. The box body (21), the free end of $ will be deformed downward. The stress, which affects the processing accuracy ^ 2 This will generally be in the box part (21) A plurality of two pieces (26) are disposed between the two side surfaces and the fixing portion (25), and an integral body (27) is further slid between the bottom surface of the box portion (21) and the fixing portion (25) to overcome the foregoing The deformation stress and the reinforcement of the structural strength; however, the ribs (26) on both sides of the box portion (21) are horizontally flaky 5 M321825 ^ to effectively withstand the downward deformation component of the box portion (21), so the box The body, i^^ is deformed downward, and even breaks, and the support (27), which has a structural strength at the bottom of the box portion (21), is solidly depicted, "when it is stressed The strain capacity is small, so it can not be effective, and the positive reinforcement effect of the /, not only affects the resistance to deformation and the structural strength of the joint / 鄕 ^ machinery in the operation is easy to cause ripples on the surface due to vibration, it directly affects The overall power and processing quality. Straight-and-deep deep 2 2 ingenuity!? People are actively looking for the R&D and manufacturing experience of the relevant industry for the stress deformation of the headstock of the Chinese style. Development, finally succeeded in the axlebox two no; wide-face _ strengthened structure' There is a problem that the strength of the spindle phase is insufficient and it is easy to deform downwards. Brother Xiuzhu [new content] The main purpose of the second is to provide a kind of deformable stress that can withstand. Strengthen the structure to avoid the headstock being deformed downward due to weight. The headstock reinforcement structure is used to enhance the flat mineral material-fixing part for transcription; the water of the machine is divided into the lower part: the side surface of the fixed side is between the upper side and the fixed side side. There are _: body household = (four) on the side surface of the box body 6 M321825 and between the bottom surface of the box body and the bottom surface of the fixed part 1 a support unit is attached to the bottom surface of the box body and fixed and supported, the branch is on the outermost side of the side The top surface of the rib and the bottom 3 = a plurality of ribs, the annular ribs, the width of the annular rib being formed between the widths of the surface - thereby, through the foregoing technical means The downward deformation of the box body when it is horizontally extended can be used to absorb the deformation amount by using the hollow interior of the support unit. Good _ n 图 坪 坪 细 细 细 细 细 细 细 细 细 细 细 细 细 细The field can be implemented in a physical way, but the people in the town are only in the context of the creation of a good example. It is not intended to limit the scope of the creation. It is based on the spirit of the creation, and any form of decoration for this creation. Or change 'w should still fall within the scope of this creative intent. [Embodiment] This creation is a spindle box reinforcement structure of a processing machine. Please refer to the second figure. The spindle box (50) includes a horizontal box body (51) for housing the spindle mechanism. The vertical fixing portion (55) is always provided, and the headstock (5〇) is fixed to the upper surface of the upper column of the vertical processing machine by the fixing portion (55), which is not the creation of the above. The characteristics are not described here; ^ For the detailed composition of this creation, please refer to the side surface (μ) of the main shaft phase (50) on both sides of the phase body part (51) as shown in the second to fifth figures. The reinforcing unit (60) corresponding to both sides of the fixed portion (55) of the solid M321825 is provided with a complex-group corresponding reinforcing unit from the top to the bottom of the circumferential surface (56) (two: on both sides of the box portion (51), The bottom edge of each of the lower edge of the box body portion (51) is the main embodiment, and the headstock box (5 〇) is placed on the struts (70); and the bottom surface of the fixing portion (55) is provided with a 51): = Table = 2 '; strong unit (6_ body part ((56) between the right side of the right side of the solid part (55) corresponding to the side of the peripheral surface Un t and the shape of the rib (61), and the reinforcement unit (60 ^ ,\ancient A U-shaped rib body is formed on the side peripheral surface (56) of the crotch portion (55) ('the U-shaped rib body (65) has one end and abuts the door-shaped rib body (61), such as a large spindle box (5G) receiving box The body (51) has a downward deformation stress, avoiding downward deformation and vibration of the box portion (51), and achieving a strong structure; ^ further as disclosed in the fifth and sixth figures, the aforementioned support unit (7〇) is formed by arranging a plurality of ribs (71) obliquely between the bottom surface (53) of the casing portion (51) and the bottom peripheral surface (57) of the fixing portion (55), and the supporting unit (7〇) And an annular rib (75) is formed between the top surface of the outermost rib (71) on both sides and the bottom surface (53) and the bottom surface (57 ru), and the width of the annular rib (75) is It is wider than the thickness of the rib (71), so that it can directly withstand the deformation stress of the box portion (51) by using the hollow support unit (70), and increase the deformation margin to improve the structure of the headstock (50). Strength and stability; By this, the group constitutes a spindle box reinforced structure with good structural strength and improved machining accuracy. As for the actual application, the second figure is As shown, the box portion (51) of the headstock (50) is provided with a reinforcing unit (6Q) and a supporting unit (the door type rib (61) between the two sides and the bottom surface and the fixing portion (8 M321825 55). ) to increase the strained surface (7G) with a hollow special design, and can directly stress deformation, effective strength of the spindle box ((8) structure Γ ΪΙΓ machine for smoothness during processing, it can greatly enhance the ^The mechanical addition degree, which can effectively increase its added value and product competition, and the creation of the ice has the above-mentioned numerous advantages.
