Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0029] As shown in Figures 1-9 A part machining device, comprising a main shaft mechanism 1 and a machining unit 3, the main shaft mechanism 1 comprises a base 11 and a rotating main shaft 12, the rotating main shaft 12 can rotate around its own center axis, or can also axially move relative to the base 11; the base 11 is provided with a moving track 2, and the machining unit 3 is movably arranged on the moving track 2, the machining unit 3 is used for mounting a tool 4, and an adjusting mechanism for adjusting the height of the tool 4 is arranged on the machining unit 3, here the height of the tool 4 refers to the horizontal height of the tool 4 relative to the rotating main shaft 12.

[0030] As an example in the direction shown by Figure 1 At least part of the moving track 2 is arranged above the rotating main shaft 12, in this embodiment, the moving track 2 is arranged above the rotating main shaft 12 as a whole, and the tool 4 moves vertically from top to bottom to approach the axis of the rotating main shaft 12.

[0031] Of course, in other embodiments, the moving track 2 can be arranged beside the rotating main shaft 12, so that part of the moving track 2 is above the rotating main shaft 12 and part of the moving track 2 is in the same horizontal plane as the rotating main shaft 12, and the tool 4 moves horizontally from left to right or from right to left to approach the axis of the rotating main shaft 12.

[0032] Whether the moving track 2 is partially above the rotating main shaft 12 or entirely above the rotating main shaft 12, the moving track 2 and the rotating main shaft 12 are arranged on the same base 11, so that the verticality of the rotating main shaft 12 and the moving track 2 can be ensured by one-time machining of the base 11, the machining precision is higher, and the machining is also easy.

[0033] The extending direction of the moving track 2 is perpendicular to the moving direction of the rotating main shaft 12 relative to the base 11, and the perpendicular herein includes Figure 1 The moving track 2 is horizontally arranged as shown, and the rotating main shaft 12 is vertically arranged relative to the paper, and also includes that the moving track 2 is vertically arranged, and the rotating main shaft 12 is vertically arranged relative to the paper, and the specific limitation is not limited.

[0034] In order to ensure the perpendicularity of the rotating main shaft 12 and the moving track 2, and ensure the matching precision of the two, the base 11 is an integral molding structure, that is, the side wall, top wall, bottom wall and the like of the base 11 are integrally connected, at this time, the rigidity of the base 11 is strong, which is beneficial to improve the machining precision.

[0035] The rotating main shaft 12 can rotate around its own center axis and can axially move relative to the base 11, specifically, the blank to be processed is installed on the rotating main shaft 12, and the rotating main shaft 12 can rotate around its own center axis while moving in the direction perpendicular to the paper. Figure 1 The rotating main shaft 12 can move in the direction perpendicular to the paper. The specific function of the main shaft mechanism 1 is prior art, and will not be described in detail.

[0036] As shown in Figure 3 , Figure 7 The adjusting mechanism includes a tool mounting groove 31 and a pressing block 33 detachably connected to the tool mounting groove 31. In the embodiment, the number of tool mounting grooves 31 is multiple, and the tool mounting grooves 31 extend along the direction perpendicular to the moving track 2, and the adjacent tool mounting grooves 31 are arranged in parallel. The tool mounting groove 31 has two opposite side walls, and the pressing block 33 is detachably installed on one side wall of the tool mounting groove 31. The tool 4 can be freely moved up and down along the tool mounting groove 31 when the pressing block 33 is removed from the tool mounting groove 31, so as to adjust the relative height thereof. By replacing different pressing blocks 33, the purpose of clamping different tools 4 can also be achieved, and the processing of different blanks can be adapted. Of course, in other embodiments, the adjusting mechanism can also be the structure in the prior art, as long as the installation, replacement and height adjustment of the tool 4 can be achieved.

[0037] In the embodiment, the blank to be processed is finally processed into a hydraulic sleeve, and the inner hole of the blank needs to be cut to form an internal threaded hole, and the outer wall of the blank also needs to be cut to achieve the target wall thickness. Therefore, the tool 4 includes a first tool 41 for processing the inner hole of the blank, and a second tool 42 for processing the outer wall of the blank. As shown in Figure 7 The cutting end 421 of the second tool 42 is vertically downwardly arranged, which means that the second tool 42 cuts the blank to be processed from the upper part of the blank, so that the cutting waste can be directly discharged from the lower part, without adversely affecting the cutting. As shown in Figure 5As shown, the central axis of the first tool 41 is arranged parallel to the rotating spindle 12, so that the first tool 41 can extend into the blank to be processed to cut the internal threaded hole.

[0038] like Figure 7 As shown, the movable track 2 includes a first slide rail 21 and a second slide rail 22 arranged in parallel, and the processing unit 3 includes a body 32, which is slidably matched with the first slide rail 21 and the second slide rail 21, and is driven by a servo motor.

[0039] In another embodiment, when the movable track 2 is vertically arranged on the side of the rotating main shaft 12 , the first slide rail and the second slide rail are arranged parallel to each other, and the cutting end of the second tool 42 is horizontally facing the rotating main shaft 12 .

The number of processing units 3 corresponds to the number of spindle mechanisms 1, and they are each movably mounted on a movable rail 2.

[0041] Specifically, in this embodiment, a frame 5 is mounted with four parts processing devices. The four spindle mechanisms 1 of the four parts processing devices are fixedly mounted in parallel on the frame 5, and the four processing units 3 are movably mounted on the bases 11 of the spindle mechanisms 1. In this case, multiple spindle mechanisms 1 can share a single feed mechanism, simplifying the overall structure and significantly reducing the floor space. The spindle mechanisms 1 can operate independently, or two or more spindle mechanisms 1 can be driven by the same power source, without limitation.

[0042] The processing process of the present invention is to adjust the relative height of the tool 4 in advance through the adjustment mechanism so that the tool 4 is adapted to the axis height of the rotating spindle 12, and the blank to be processed is placed on the rotating spindle 12, and the rotating spindle 12 drives the blank to rotate, or the rotating spindle 12 drives the blank to rotate, and at the same time the rotating spindle 12 can move relative to the base 11 close to the processing unit 3, which can be specifically driven by a servo motor or any driving structure in the prior art; the processing unit 3 translates along the moving track 2 so that the cutting end 421 of the second tool 42 contacts the blank, and the outer wall of the blank is processed when the rotating spindle 12 drives the blank to rotate. At this time, it is necessary to spray coolant on the blank, and the specific setting position of the spray port is not limited; the processing unit 3 translates along the moving track 2 so that the center axis of the first tool 41 overlaps with the rotating spindle 12, the first tool 41 moves and extends into the center of the blank, or the rotating spindle 12 drives the blank close to the first tool 41 to complete the processing of the inner hole.

[0043] When the workpiece needs to be machined by a different second tool 42, the machine is stopped for adjustment, avoiding interference of the second tool 42 used in the previous step, and the relative height of the tool 4 is adjusted by the adjusting mechanism, so that the height of the tool 4 and the axis of the rotating main shaft 12 is matched, and then the machining on the rotating main shaft 12 is machined.

[0044] The above specific embodiments are used to explain and illustrate the present application, rather than limit the present application, and any modification and change made to the present application within the spirit and protection scope of the claims of the present application shall fall into the protection scope of the present application.
