DETAILED DESCRIPTION

[0039] To make the purpose, technical scheme and advantages of the embodiments of the utility model more clear, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0040] A kind of composite material horizontal machining center, combine Figures 1 to 19 As shown in the figure, Figure 2The thick lines in the middle are force diagrams, including: the bed body 1, the column 2, the sliding table 3, the rotary table 4 and the main shaft 5, the column 2 is arranged on the bed body 1 and moves along the X-axis direction in the horizontal plane, the sliding table 3 is arranged on the column 2 and moves along the Y-axis direction in the vertical plane, and the rotary table 4 is arranged on the bed body 1 and moves along the Z-axis direction in the horizontal plane; the rotary table 4 is located on one side of the column 2, the main shaft 5 is arranged on the sliding table 3 and faces the rotary table 4, and the main shaft 5 is arranged parallel to the Z-axis direction; the rotary table 4 is a non-orthogonal rotary table, the support force of the bed body 1 on the column 2 is perpendicular to the X-axis direction and inclined relative to the Z-axis direction, and the support force of the bed body 1 on the column 2 points to the machining area. By arranging the non-orthogonal rotary table and inclining the support force of the bed body 1 on the column 2 and pointing to the machining area, a double-inclined structure is formed; and the horizontal component of the support force of the non-orthogonal rotary table on the rotating part and the support force of the bed body 1 on the column 2 can offset the cutting resistance and rebound force in the cutting process, and the arrangement of the bed body 1, the column 2 and the rotary table 4 forms a triangular structure, which ensures the high rigidity of the horizontal machining center as a whole, thereby realizing heavy cutting.

[0041] Specifically, the bed body 1 is arranged on the foundation 9 and serves to support and fix the machining center, and the foundation 9 is composed of a high-quality gravel bottom layer, a reinforced concrete layer and an asphalt vibration absorption layer.

[0042] Preferably, two groups of X-axis driving mechanisms arranged in a stepped manner are arranged between the bed body 1 and the column 2, for example, Figure 3 The two groups of X-axis driving mechanisms drive the column 2 to move horizontally along the X-axis direction. One group of X-axis driving mechanisms far from the rotary table 4 is higher than the other group of X-axis driving mechanisms, so that the resultant force of the support forces of the two groups of X-axis driving mechanisms on the column 2 is inclined upward and points to the machining area. The stepped arrangement of the two groups of X-axis driving mechanisms can increase the distance between the two groups of X-axis driving mechanisms, thereby improving the rigidity of the column 2; at the same time, the materials originally belonging to the column 2 can be transferred to the bed body 1, thereby reducing the weight of the column 2 and improving the ability of the two groups of X-axis driving mechanisms to drive the column 2 to accelerate, thereby shortening the cycle time and improving the machining efficiency.

[0043] Preferably, two groups of X-axis guiding mechanisms are further arranged between the bed body 1 and the column 2, and the two groups of X-axis guiding mechanisms are located on the two sides of the two groups of X-axis driving mechanisms, and one group of X-axis guiding mechanisms far from the rotary table 4 is higher than the other group of X-axis guiding mechanisms. The two groups of X-axis guiding mechanisms guide and support the column 2, further ensuring the rigidity and movement accuracy of the column 2.

[0044] Specifically, the bed body 1 is provided with a column supporting surface, the column supporting surface includes a first supporting surface, a second supporting surface, a third supporting surface and a fourth supporting surface which are successively raised in the direction of the rotary table 4 facing the column 2, the two groups of X-axis guiding mechanisms are respectively arranged on the first supporting surface and the fourth supporting surface, and the two groups of X-axis driving mechanisms are respectively arranged on the second supporting surface and the third supporting surface.

[0045] Specifically, the bottom of the column 2 is provided with a column mounting surface, which is adapted to the column support surface, the two sets of X-axis guide mechanisms and the two sets of X-axis drive mechanisms.

[0046] Specifically, the slide table 3 is located on the side of the column 2 facing the rotary table 4, and the slide table 3 and the column 2 are provided with two sets of Y-axis drive mechanisms and two sets of Y-axis guide mechanisms located outside the two sets of Y-axis drive mechanisms. The two sets of Y-axis drive mechanisms drive the slide table 3 to move vertically along the Y-axis direction, and the two sets of Y-axis guide mechanisms guide and support the slide table 3.

[0047] Specifically, the main shaft 5 is installed on the main shaft box, and the main shaft box is installed on the slide table 3, which serves to connect the main shaft 5 and the slide table 3.

[0048] Specifically, the rotary table 4 and the bed 1 are provided with two sets of Z-axis drive mechanisms and two sets of Z-axis guide mechanisms located outside the two sets of Z-axis drive mechanisms. The two sets of X-axis drive mechanisms drive the rotary table 4 to move horizontally along the Z-axis direction, so as to realize the approach and departure of the rotary table 4 to the column 2; and the two sets of Z-axis guide mechanisms guide and support the rotary table 4.

[0049] Preferably, the rotary table 4 is a 45° non-orthogonal rotary table, as shown in the arrows. Figure 4 and Figure 5 As shown by the arrows, compared with the traditional cradle type, the 45° non-orthogonal rotary table has the center of gravity of the workpiece closer to the rotation center, the change of the center of gravity during the machining process is small, the transmission of the moment is reduced, the cutting loop (the distance between the workpiece and the motion control system) is shorter, the machining rigidity is improved, and a larger cutting amount can be removed. Therefore, the 45° non-orthogonal rotary table has better rigidity, a larger rotation angle, smaller interference and smaller rotational inertia. At the same time, since the rotation axis is close to the center of gravity of the workpiece, the centrifugal force generated during rotation is small, the acceleration of the motor can reach a higher level, thereby improving the efficiency. And the small centrifugal force generated is small to the movement wear of each part of the rotary table 4, so that the dynamic accuracy can be maintained for a long time.

[0050] Specifically, the rotary table 4 includes a swing shaft unit, a rotary shaft unit and a working rotary table 43, the swing shaft unit includes a swing shaft rocker arm 411, the rotary shaft unit includes a rotary shaft rocker arm 421, the swing shaft unit drives the rotary shaft unit to rotate around the C-axis, and the rotary shaft unit drives the working rotary table 43 to rotate around the B-axis.

[0051] Specifically, the X-axis drive mechanism, the Y-axis drive mechanism and the Z-axis drive mechanism adopt high-precision and high-strength inner circulation small lead ball screws, and the driving motor is directly connected to the screw without backlash through a rigid coupling. High-precision grating rulers are used for full-closed-loop control to achieve high-precision control effect.

[0052] Specifically, the X-axis guide mechanism, the Y-axis guide mechanism and the Z-axis guide mechanism adopt high-precision linear guides.

[0053] Preferably, it further comprises a separated chip removal structure, such as Figure 6 as shown in FIG. 6, Figure 6 The arrow in FIG. 6 indicates the direction of chip movement. The separated chip removal structure comprises a middle chip removal groove 61, two side chip removal grooves 62, two sets of machine tool protective covers 63 and three chip removers.

[0054] The middle chip removal groove 61 is located between the two side chip removal grooves 62, and a set of Z-axis driving mechanisms is arranged between the middle chip removal groove 61 and the two side chip removal grooves 62. The two sets of machine tool protective covers 63 protect the two sets of Z-axis driving mechanisms, respectively. The three chip removers are arranged in the middle chip removal groove 61 and the two side chip removal grooves 62, respectively. The separated chip removal structure has many advantages over the traditional chip removal structure and can easily cope with a large amount of chip removal. First, the height of the machine tool protective cover can be reduced. The traditional chip removal structure needs to have a longer and steeper slope to ensure that the chips are quickly removed. However, the span of the two sets of Z-axis driving mechanisms makes the height of the machine tool protective cover of the traditional chip removal structure higher. However, the span of the single machine tool protective cover 63 is reduced, which can reduce the height when achieving the same slope, thereby improving the space utilization of the machining center. Second, the height of the rotary table 4 can be reduced. Since the height of the machine tool protective cover is reduced, the height of the rotary table 4 connected thereto can also be reduced, which can lower the center of gravity of the rotary table 4, thereby improving the rigidity of the rotary table 4, expanding the operating range of the workpiece and increasing the operating range of the main shaft 5. Third, the chip removal speed can be improved. The middle chip removal groove is added in the middle part of the two sets of Z-axis driving mechanisms. A part of the chips can directly fall into the middle chip removal groove 61, reducing the residence time of the chips in the machining center. Another part of the chips falls on the two sets of machine tool protective covers 63 and is quickly removed into the middle chip removal grooves 61 and the side chip removal grooves 62 on the two sides through the shorter slope thereof. The chips in the middle chip removal grooves 61 and the two side chip removal grooves 62 are quickly removed by the three chip removers, which can reduce the influence of the chips on the temperature of the machining center.

[0055] Preferably, it further comprises a tool magazine 7 provided with an automatic tool changing system 71 to store and replace tools, thereby improving the machining efficiency.

[0056] Specifically, the tool magazine 7 adopts a chain tool conveying system installed on the foundation on one side of the bed 1, and the tool axis is arranged parallel to the Z-axis direction. The automatic tool changing system 71 adopts an ATC automatic tool changing system.

[0057] Preferably, the bed body 1, the column 2, the sliding table 3, the rotary table 4 and the spindle box are casted by mineral cementing material. The thermal conductivity of the mineral cementing material under the condition of being heated is only 1 / 20 of that of gray cast iron. In a unit of time, the temperature rise of the bed body 1, the column 2, the sliding table 3, the rotary table 4 and the spindle box affected by external heat radiation is small, so that the deformation amount of the bed body 1, the column 2, the sliding table 3, the rotary table 4 and the spindle box is small, thereby ensuring the shape accuracy of the bed body 1, the column 2, the sliding table 3, the rotary table 4 and the spindle box. Further, the influence of the heat source on the temperature of the machining center is reduced, the thermal deformation of each component of the machining center in the working process is reduced, the matching accuracy of each component is ensured, and the machining center can maintain stable geometric accuracy, motion accuracy, positioning accuracy and repeat positioning accuracy in a long working process.

[0058] In the working process of the machining center, each moving component is prone to vibration in the movement process, so that each moving component and its connected components vibrate synchronously, the motion accuracy and position accuracy of each moving component are reduced, and further the machining accuracy is affected. The application utilizes the characteristics of the mineral cementing material having good damping performance to realize absorbing the vibration of each moving component and its connected components, reduce the vibration amplitude, and keep the relative position between the relative moving components stable, so that the matching gap between the relative moving components is not easily changed, and the motion accuracy, positioning accuracy and repeat positioning accuracy of the machining center are ensured.

[0059] Specifically, the mineral cementing material is selected from cast stone or foamed cement material. Compared with traditional cast iron material, the thermal conductivity of the cast stone is only 1 / 20 of that of cast iron, and the cast stone is not sensitive to short-term environmental temperature changes. Under the influence of the same heat in a unit of time, the deformation amount of the structure affected by temperature is smaller than that of the cast iron material, so that the accuracy of the structure is ensured. Compared with traditional cast iron material, the damping characteristic value of the cast stone is 6-10 times that of the cast iron, and the mineral cementing material of the cast stone material can reduce the influence of vibration, keep the relative position between each moving component of the machining center and the bed body 1 stable, and enable the machining center to maintain stable high accuracy in the working process. The thermal conductivity of the foamed cement is small, and the foamed cement is not sensitive to short-term environmental temperature changes. The porous structure of the foamed cement itself has good vibration absorption capacity, and the influence of vibration on the relative position accuracy and geometric accuracy between each moving component and the bed body 1 is reduced.

[0060] Specifically, the performance comparison of the gray cast iron, the cast stone and the foamed cement material refers to the related content in the patent with the authorized publication number CN219005241U and the name of “A vertical machining center”.

[0061] Preferably, the bed body 1, the column 2, the sliding table 3, the rotary table 4 and the spindle box are respectively provided with metal inserts, which provide interfaces for installing other workpieces. The compressive strength and tensile strength of the mineral cementitious material are not as good as those of gray cast iron, and the metal inserts can make up for the deficiency in strength of the mineral cementitious material to ensure the overall rigidity of the casting; and the metal inserts are convenient for finishing, which can ensure the connection strength and installation accuracy between the moving parts and between the moving parts and the bed body 1.

[0062] Specifically, the metal inserts are preferably steel inserts with high strength, which can not only ensure the rigidity but also utilize the similar thermal expansion coefficients of the two. The metal inserts are symmetrically and uniformly distributed inside the corresponding parts, and the heat of the mineral cementitious material can be conducted to the steel inserts, so that a uniform temperature field is generated on the parts under the action of multiple symmetrically distributed steel inserts, the temperature fields of the parts are similar, and the thermal radiation of the parts has linearity and regularity.

[0063] Preferably, the metal inserts are fixed with connecting parts embedded in the mineral cementitious material, which increase the contact area and connection strength of the metal inserts and the main body of the mineral cementitious material of each part.

[0065] The foot inserts 11 are multiple, and the multiple foot inserts 11 are symmetrically distributed on the lower end surface of the bed body 1. When the bed body 1 is heated, the heat of the bed body 1 is easily conducted to the foot inserts 11, so that the temperature of the bed body 1 is symmetrically distributed under the action of multiple symmetrically distributed inserts, and then the heat dissipation area, heat conduction path and mass of the parts of the bed body 1 are symmetrically distributed, thereby reducing the thermal deformation of the bed body 1. The connecting part of the foot insert 11 is a plurality of connecting columns, which are inserted into the mineral cementitious material, and the outer periphery of the foot insert 11 is provided with a groove for improving the bonding strength with the mineral cementitious material.
