[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly disposed on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element. When an element is referred to as being "mounted on" another element, it may be directly mounted on the other element or there may be a central element.

[0040] In addition, it should be understood that all directional indications in the embodiments (such as up, down, left, right, middle, etc.) are only used to explain the relative position relationship, movement, etc. between the components in a certain posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly; the terms "first", "second", etc. are used to distinguish different structural components. These terms are only simplified descriptions for the convenience of describing the utility model and cannot be understood as limitations on the utility model.

[0041] The processing head main body component provided by the utility model is mainly used in a horizontal processing center, that is, the spindle is arranged horizontally. The processing head main body component may include a saddle and a ram, and the ram is used to install the spindle, which can be horizontally telescopically arranged on the saddle to support and drive the spindle to extend or retract for processing.

[0042] See also Figures 2 to 5 The processing head main body assembly provided by the utility model may include a saddle 11 and a ram 12 for mounting a spindle 13, and the ram 12 may be horizontally telescopically arranged on the saddle 12. In the figure, the ram 12 is roughly a square ram body 121, and accordingly, the saddle 12 has a corresponding structure adapted to the shape.

[0043] The saddle 11 has adjacent horizontal mounting surfaces 112 and vertical mounting surfaces 113, and the ram 12 has adjacent first connecting surfaces 122 and second connecting surfaces 123. The first connecting surface 122 is disposed face-to-face with the horizontal mounting surface 112 and is track-matched, and the second connecting surface 123 is disposed face-to-face with the vertical mounting surface 113 and is track-matched. Accordingly, the ram 12 and the saddle 11 cooperate with each other to realize the telescopic movement of the ram 12 in the horizontal direction. It can be understood that the adjacent mentioned here means approximately adjacent. In order to reduce weight, some chamfers, drillings and / or other mounting structures can be set between the two surfaces.

[0044] Combination Figure 2 , Figure 3 and Figure 4 In the present invention, a first track fitting member 124 is provided on the first connection surface 122, and a second track fitting member 125 is provided on the second connection surface 123. The extension direction of the first track fitting member 124 is parallel to the extension direction of the second track fitting member 125. The position of the first track fitting member 124 on the first connection surface 122 and the position of the second track fitting member 125 on the second connection surface 123 are respectively located on both sides of the vertical center plane 1 of the ram. Figure 3 It is preferably described at the maximum straight-line distance between the two.

[0045] Figure 3In the figure, the maximum horizontal distance of the first connection surface 122 is a, and the maximum vertical distance of the second connection surface 123 is b. If the distance between the first track fitting member 124 and the second track fitting member 125 is to be the farthest, that is, to meet the maximum straight-line distance between the two, the first track fitting member 124 needs to be set at the point p of the first connection surface 122, that is, at the left edge of the first connection surface 122; at the same time, the second track fitting member 125 is set at the point q of the second connection surface 123, that is, at the top edge of the second connection surface 122. Here, the first track fitting member 124 and the second track fitting member 125 are both guide rails, and accordingly, the horizontal mounting surface 112 and the vertical mounting surface 113 are both provided with sliders 116 that match the corresponding guide rails.

[0046] The ram 12 and the saddle 11 are matched with each other through two adjacent surfaces, and the first track matching member 124 and the second track matching member 125 are used to form a telescopic support and support between the ram 12 and the saddle 11, and the spacing between the first track matching member 124 and the second track matching member 124 is set to be on both sides of the vertical center plane of the ram, so that the processing rigidity is better and the anti-deformation ability is stronger, especially when the two are at the maximum straight-line distance, the stability of the telescopic action of the ram 12 relative to the saddle 11 is guaranteed, and at the same time, the production process of the ram 12 and the saddle 11 is reduced, the production complexity is simplified, the processing and manufacturing difficulty caused by setting too many tracks is reduced, the production cost is reduced, the production efficiency is improved, and the operation stability of the main assembly of the processing head is taken into account. In addition, the difficulty of assembling the ram 12 to the saddle 11 is also reduced.

[0047] In the present invention, the saddle 11 may specifically include a first mounting groove 114, the horizontal mounting surface 112 is located at the bottom of the first mounting groove 114, and the vertical mounting surface 113 is located on the side wall of the first mounting groove 114. Accordingly, the ram 12 can be assembled in the first mounting groove 114 by the staff. Furthermore, a second mounting groove 115 for installing a driving device is also provided at the bottom of the first mounting groove 114, and sliders 116 cooperating with the corresponding guide rails are respectively located on both sides of the second mounting groove 115. The driving device is used to drive the ram 12 to extend and retract relative to the saddle 11, and the driving device may be a linear motor or a screw pair.

[0048] Here, it is preferably a screw pair, and accordingly, a screw motor mounting plate 1151 and a screw tailstock 1152 are also provided on the slide saddle 11, both of which are arranged in the second mounting groove 115, and the groove body between the two is used to provide a linear motion space for the nut and the nut seat on the slide ram 12. Further, in order to reduce the possible jitter between the assemblies, the screw motor mounting plate 1151 and the screw tailstock 1152 arranged in the second mounting groove 115 are integrally formed with the slide saddle body 111.

[0049] Combination Figure 2 and Figure 4 , the saddle 11 has a power connection part 117, and the power connection part 117 is located on the side of the vertical mounting surface 113 facing the side wall of the first mounting groove 117, and the slider 116 on the horizontal mounting surface 112 is located between the power connection part 117 and the second mounting groove 115. The power connection part 117 can drive the entire saddle 11 to move up and down under the action of external power. Placing a horizontally arranged slider closer to the lifting action can effectively reduce the probability of unnecessary shaking of the slide 12 during the lifting process, resulting in loss of precision. Preferably, a single-sided method is used here to drive the saddle up and down, which can reduce the number of drive settings and reduce the complexity of control.

[0050] In the present invention, the processing head main body assembly may further include a column 14 having a door frame 141 , and a lifting drive device 15 is provided on the column 14 . The lifting drive device 15 can be used to drive the saddle 11 to rise and fall in the door frame 141 .

[0051] like Figure 4 and Figure 5 As shown, the door frame 141 may include two vertical plates 142 with parallel plate surfaces, and a crossbeam 143 disposed on the top of the two vertical plates 142. The front end plate edges 1421 of the two vertical plates 142 are used to face the side where the workbench is located. It can be understood that the parallelism here is not an absolute parallelism. The plate surfaces of the two vertical plates 142 are substantially parallel and are also within the protection range of the parallel arrangement.

[0052] In the present invention, considering the better column load-bearing structure, deadweight and processing requirements at corresponding heights, the door frame 141 is designed as follows:

[0053] (1) The lengths of the two vertical plates 142 in the horizontal direction are shortened from bottom to top, that is, the horizontal length of the vertical plate 142 at the lowest point of the vertical plate 142 in the Z-axis direction is the maximum value, and the horizontal length of the vertical plate 142 at the highest point is the minimum value; or,

[0054] (2) The height of the two vertical plates 142 decreases from front to back, that is, the height of the vertical plates 142 in the Y-axis direction is the maximum at the front end and the minimum at the rear end.

[0055] It is understandable that the vertical plate 142 may be shortened gradually or in sections during the shortening process in the corresponding direction.

[0056] In addition to the vertical plates 142 and the cross beams 143 , the door frame 141 may further include a bottom plate 144 disposed between the two vertical plates 142 . The bottom plate 144 is located at the bottom of the two vertical plates 142 .

[0057] Furthermore, a stepped structure of a primary table 1441 and a secondary table 1442 is provided on the bottom surface of the bottom plate 144, wherein the setting height of the primary table 1441 is lower than the setting height of the secondary table 1442, the primary table 1441 is located at the front end of the bottom plate 1441, and the secondary table 1442 is located at the rear end of the bottom plate 1442. Here, the primary table 1441 and the secondary table 1442 are both used to install corresponding sliders or guide rails, and the front and rear rail installation with high and low offset settings can provide a component force in an inclined direction for the ram 12 and the spindle 13 therein that are telescopic relative to the saddle 11, so that the telescopic ram 12 can support the spindle for processing more stably, which helps to reduce the instability caused by the change of the center of mass of the assembly caused by the ram 12 driving the spindle 13 to telescope.

[0058] In the present invention, the front end plate edges 1421 of the two vertical plates 142 are provided with linear rails 1422 extending in the vertical direction, and the saddle 11 is also provided with a linear rail slider 118 cooperating with the linear rails 1422. Similarly, the track matching structure between the ram 12 and the saddle 11 can also specifically adopt this linear rail matching structure. The lifting drive device 15 can also be specifically a screw pair, and the power connection part 117 can also be a nut seat structure of the nut connection of the lifting drive device 15.

[0059] The utility model also provides a machining center, which includes a base, and the machining head main body assembly as described above is movably arranged on the base. More specifically, a fixed workbench, a cradle or a turntable may also be provided on the base, and the machining head main body assembly may face the side where the workbench is located to support the ram to drive the spindle to extend and retract to process the workpiece on the workbench. Here, the machining center equipped with the corresponding machining head main body assembly has better machining rigidity and stronger deformation resistance, which ensures the stability of the ram's telescopic action relative to the saddle, while reducing the production process of the ram and the saddle, simplifying the production complexity, reducing the difficulty of machining and manufacturing caused by setting too many tracks, reducing production costs, improving production efficiency, taking into account the running stability of the machining head main body assembly, and the assembly difficulty is relatively low.

[0060] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0061] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
