[0034] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0035] See also Figure 1-Figure 4 In order to solve the problems in the prior art, the present invention provides a CNC double-station vertical lathe 1, which includes a frame assembly 11 and two sets of processing devices 12. The two sets of processing devices 12 are both located on the frame and symmetrically distributed along the left and right sides of the frame. The processing device 12 includes a first cutter head assembly 121, a second cutter head assembly 122 and a workpiece clamping assembly 123;

[0036] The frame assembly 11 includes a chassis 111, a first vertical plate 112 and a second vertical plate 113. The first vertical plate 112 and the second vertical plate 113 are both fixed on the chassis 111, and the first vertical plate 112 and the second vertical plate 113 are perpendicular to each other.

[0037] The first cutter head assembly 121 includes a first turret 1211, a first support plate 1212 and a second support plate 1213. The first support plate 1212 is slidably connected to the first vertical plate 112 and can slide in the vertical direction. The second support plate 1213 is slidably connected to the first support plate 1212 and can slide in the horizontal direction. The first turret 1211 is slidably connected to the second support plate 1222 and can slide in the vertical direction.

[0038] The second cutter head assembly 122 includes a second turret 1221 and a third support plate 1222. The third support plate 1222 is slidably connected to the second vertical plate 113 and can slide in the vertical direction. The second turret 1221 is slidably connected to the third support plate 1222 and can slide in the horizontal direction.

[0039] The workpiece clamping assembly 123 includes a clamping jaw and a clamping driving member. The clamping driving member is located in the chassis 111. The clamping jaw is mounted on the chassis 111 and connected to the clamping driving member to clamp the part 2. The clamping driving member drives the clamping jaw to drive the part 2 to rotate.

[0040] The first turret 1211 and the second turret 1221 are both located above the clamp, and the first turret 1211 and the second turret 1221 are both located on the horizontal diameter of the part 2 and can slide along the direction of the horizontal diameter.

[0041] Taking the processing device 12 on one side as an example, when processing part 2, first place the part 2 to be processed on the clamping jaws of the chassis 111 and clamp the part 2, and drive the clamping jaws to drive the part 2 to rotate through the clamping drive member. Then, in the first cutter disc assembly 121, the first support plate 1212 and the second support plate 1213 drive the first turret 1211 to move horizontally and vertically, so that the tool on the first turret 1211 can cut the end face of part 2. In the second cutter disc assembly 122, the third support plate 1222 drives the second turret 1221 to move horizontally and vertically, so that the tool on the second turret 1221 can cut the cylindrical surface of part 2, thereby realizing the operation of simultaneously processing the end face and the cylindrical surface of part 2 at one processing station, thereby improving the processing efficiency of part 2.

[0042] In the processing device 12 on the other side, the same operation as above can be performed, so that the two parts 2 can be cut and processed simultaneously under the action of the CNC double-station vertical lathe 1, thereby further improving the processing efficiency of the parts 2.

[0043] Since the first turret 1211 and the second turret 1221 are both located on the horizontal diameter of the part 2, when the first turret 1211 drives the tool to perform cutting processing, the second support plate 1213 can drive the tool on the first turret 1211 to perform cutting processing on the end face of the part 2 under the horizontal movement. When the second turret 1221 drives the tool to perform cutting processing, the third support plate 1222 can drive the tool on the second turret 1221 to perform cutting processing on the cylindrical surface of the part 2 under the vertical movement, thereby avoiding collision between the first turret 1211 and the second turret 1221 when performing simultaneous processing.

[0044] Since the first turret 1211 is located on the first vertical plate 112, the second turret 1221 is located on the second vertical plate 113, and the first vertical plate 112 and the second vertical plate 113 are perpendicular to each other, by pre-setting the cutting amount of the first turret 1211 and the second turret 1221, the first turret 1211 can drive the tool to cut the end surface on the right side of the part 2, and the second turret 1221 can drive the tool to cut the end surface on the left side of the part 2, so as to improve the processing efficiency when the first turret 1211 and the second turret 1221 simultaneously cut the end surface of the part 2, and also avoid the first turret 1211 and the second turret 1221 from colliding when performing simultaneous processing.

[0045] In the embodiment of the present invention, side panels 114 are respectively provided on both sides of the first vertical panel 112 , the first vertical panel 112 is fixed to the chassis 111 through the side panels 114 , and a processed gap is formed between the bottom of the first vertical panel 112 and the chassis 111 .

[0046] By arranging side plates 114 on both sides of the first vertical plate 112, and forming a processing gap between the first vertical plate 112 and the chassis 111 under the action of the side plates 114, a large-diameter disc can be placed on the chassis 111 under the action of the processing gap, thereby increasing the processing size range of the part 2 of the CNC double-station vertical lathe 1, and then the first cutter head assembly 121 and the second cutter head assembly 122 can simultaneously process the part 2, so that the first turret 1211 drives the tool to cut the end face of the part 2, and the second turret 1221 drives the tool to cut the cylindrical surface and / or end face of the part 2, thereby improving the processing efficiency of the part 2.

[0047] See also Figure 5In an embodiment of the present invention, both sides of the first vertical plate 112 are slidably connected to the side plates 114. The processing device 12 also includes a vertical plate driving member 124, a transmission gear 125 and a transmission rack 126. The transmission rack 126 is fixed on the first vertical plate 112. The vertical plate driving member 124 is installed on the side plate 114 and meshes with the transmission rack 126 through the transmission gear 125. When the transmission gear 125 rotates, it drives the transmission rack 126 to drive the first vertical plate 112 to rise and fall to adjust the height of the processing gap.

[0048] By installing the vertical plate driving member 124 on the side plate 114 and connecting the vertical plate driving member 124 to the first vertical plate 112 through the transmission gear 125 and the transmission rack 126, the first vertical plate 112 can be driven to rise and fall under the action of the vertical plate driving member 124 to adjust the height of the processing gap. Therefore, when the length and diameter of the part 2 are relatively large, the height of the processing gap can be increased so that the part 2 can be placed on the chassis 111, further improving the size range of the part 2 processed by the CNC double-station vertical lathe 1, and enabling the first cutter head assembly 121 and the second cutter head assembly 122 to cut the part 2 at the same time, thereby increasing the processing efficiency of the part 2.

[0049] See also Figure 3 In an embodiment of the present invention, the first cutter disc assembly 121 also includes a first driving member 1214, a second driving member 1215, a third driving member 1216 and a fourth driving member. The first driving member 1214 is installed on the first vertical plate 112 and connected to the first support plate 1212 to drive the first support plate 1212 to slide in the vertical direction. The second driving member 1215 is installed on the first support plate 1212 and connected to the second support plate 1213 to drive the second support plate 1213 to slide in the horizontal direction. The third driving member 1216 is installed on the second support plate 1213 and connected to the fourth driving member to drive the fourth driving member to slide in the vertical direction. The fourth driving member is connected to the first turret 1211 to drive the first turret 1211 to rotate.

[0050] The first support plate 1212 is driven to move in the vertical direction by the first driving member 1214 to adjust the position of the first turret 1211 in the height direction, the second support plate 1213 is driven to move in the horizontal direction by the second driving member 1215 to adjust the position of the first turret 1211 in the horizontal direction, the turret is driven to move in the vertical direction by the third driving member 1216 to adjust the position of the first turret 1211 in the height direction again, so that after the height of the first vertical plate 112 changes, the turret is driven by the third driving member 1216 to perform height compensation in the height direction, and the first turret 1211 is driven to rotate by the fourth driving member, so that the first turret 1211 can replace different tools to perform cutting processing on part 2.

[0051] In an embodiment of the present invention, the second cutter disc assembly 122 also includes a fifth driving member 1223, a sixth driving member 12251224 and a seventh driving member.

[0054] By setting the third support plate 1222 to a T-shape, so that one side of the third support plate 1222 is slidably connected to the second vertical plate 113, and the other side of the third support plate 1222 is slidably connected to the second turret 1221, the second turret 1221 can be driven to rise and fall when the third support plate 1222 is raised and lowered along the second vertical plate 113, and the second turret 1221 can be driven to slide horizontally along the third support plate 1222 under the action of the sixth driving member 12251224, so that the second turret 1221 drives the tool to perform cutting processing on part 2.
