Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a mechanical processing machine with a vertical and horizontal double axis, wherein a clutch is arranged for the main shaft head of the processing machine. Background Art

[0002] In the past, milling machines and other cutting machines were divided into vertical machines or horizontal machines. According to different processing requirements of workpieces, the workpieces were moved to the vertical machine or the horizontal machine for cutting, which caused the disadvantage of time-consuming operation. Therefore, Taiwan Patent Certificate No. M533551 "Spindle head with vertical and horizontal bidirectional spindles" (hereinafter referred to as: reference case) developed a vertical and horizontal bidirectional spindle structure in response to this.

[0003] The main features of the referenced case include: one end of a first shaft is rotatably inserted into a housing and the other end protrudes from the housing, one end of the first shaft in the housing forms a bevel gear, a first main shaft is rotatably inserted into the housing at 90 degrees relative to the first shaft and is located below the first shaft, a first gear is axially sleeved on the first main shaft, the first gear is meshed with the bevel gear end of the first shaft, a second main shaft is rotatably inserted into the housing at 90 degrees with the first main shaft, a second gear is axially sleeved on the first shaft in the housing, a third gear The wheel is arranged in the housing and is located between the first shaft and the second main shaft, the third gear is meshed with the second gear, a fourth gear is axially sleeved on the second main shaft, and the fourth gear is meshed with the third gear; the second main shaft, the first main shaft and the first shaft are all equipped with gears and driven by the meshing of the gears, when the first shaft rotates, the first main shaft and the second main shaft are driven to rotate together, thereby multiple surfaces can be processed at the same time, there is no need to change the machine table and time can be saved, and the vertical spindle and the horizontal spindle are on the same spindle head to save space occupied during processing.

[0004] The technology of the referenced case can process different workpieces on a processing machine without changing the machine; however, the first axis of the referenced case meshes with the first spindle, and the second spindle is driven by the second axis between the horizontal first spindle and the longitudinal second spindle. Therefore, when the workpiece is processed by the processing head of the first spindle, the power is input to the first axis, so that the first axis drives the processing head of the first spindle to process the workpiece. However, if the processing head of the second spindle does not need to process the workpiece, it will still rotate due to the rotation of the first spindle, and then drive the second axis to link the second spindle, so that the first spindle rotates for processing, and the processing head of the second spindle still has to operate even if there is no processing operation, which wastes the input power of the first axis, increases the wear of the first axis, the second axis, the second spindle and their related components, and reduces the service life of the machine parts. Summary of the invention

[0005] In view of the above problems, the inventors have conducted further research and development. Therefore, the main purpose of the present invention is to provide a vertical and horizontal bidirectional spindle head with a clutch, which mainly installs a clutch on the spindle head. Through the clutch control, when the first spindle for vertical processing is driven to rotate, the second spindle for horizontal processing will not rotate, thereby reducing power output loss and machine wear and increasing service life.

A through hole is axially arranged throughout the driving wheel. The key part is locked and fixed to the outer side surface of the second main shaft corresponding to the displacement stroke of the driving wheel, and is protruding relative to the outer side surface of the second main shaft. The cross-section of the through hole is concave-convex due to the non-circular cross-section corresponding to the key part, so that the driving wheel can rotate with the second main shaft and the driving wheel can be axially displaced along the key part. The stop ring is fixed to the end of the shaft body of the driving wheel and is blocked by the ring seat through the stop ring.

[0011] As a further improvement of the present invention, a bearing is sleeved between the inner wall of the ring seat and the outer side surface of the shaft body of the driving wheel, so that the rotation of the driving wheel does not interfere with the ring seat. The ring seat is locked and fixed at a place on the outer side wall for the base of the shift block. The ring seat forms a protruding rib corresponding to the base, and the base forms a corresponding groove, which are connected by concave-convex matching.

[0012] As a further improvement of the present invention, the shift block of the clutch has a through hole transversely formed in the arm portion thereof to plug and fix a shaft sleeve, so that the first end of the shift control shaft is passed through the inner side of the shaft sleeve and the shift control shaft can rotate in the shaft sleeve.

[0017] 1. The present invention mainly installs a clutch on a spindle head for vertical and horizontal bidirectional processing with a first and a second spindle, and a linkage gear set is provided between the first and the second spindle for linkage meshing. When processing is performed on the first spindle, the present invention can prevent the second spindle that does not need to be processed from being linked; wherein, the clutch is used to shift the driving wheel of the second spindle that is meshed with the linkage gear set, thereby releasing and temporarily cutting off the linkage relationship between the second spindle and the first spindle. Therefore, when the first spindle performs vertical processing and milling, the power of the first spindle will not be transmitted to the second spindle, thereby reducing the power loss, effectively increasing the service life of the machine parts, and reducing the noise of the machine parts; on the contrary, when the first and the second spindles need to work on different processing surfaces at the same time, the clutch is controlled to shift the driving wheel back to its original position and re-engage with the linkage gear set, so that the power of the first spindle can be output, and the second spindle can be linked through the linkage gear set, so that the first and the second spindles can perform processing on different processing surfaces, which is quite practical and convenient.

[0018] 2. The clutch of the present invention includes changes to the driving wheel, as well as an overall combination of a ring seat, a shift block, a shift control shaft, and a positioning seat. As long as force is applied to pull the shift control shaft, the shift block, the ring seat, and the driving wheel can be linked, so that the driving wheel is displaced and the state of the driving wheel meshing with the linked gear set can be released; the operation is convenient and fast, and the clutch state of the driving wheel and the linked gear set is clearly and effectively positioned.

[0058] The present invention provides a vertical and horizontal bidirectional spindle head with a clutch, please refer to Figure 1 , 2 3. Basically, the spindle head 10 includes a base 12, a first spindle 20 rotatably mounted on one side of the base 12, a second spindle 40 mounted on one end of the base 12, and a linkage gear set 50 orthogonally driven by the first spindle 20. The linkage gear set 50 can mesh with and link the first and second spindles 20 and 40. The first spindle 20 is provided with a vertical processing end 30, and the second spindle 40 is provided with a horizontal processing end 35. The present invention mainly sets a clutch 60 on one side of the base 12; the clutch 60 is used to control the second spindle 40 to disengage or mesh with the linkage gear set 50, thereby generating a state of linkage or not with the first spindle 20.

[0059] The following describes the relationship between the first main shaft 20, the second main shaft 40, the linkage gear set 50, and the clutch 60 of the present invention. Figure 3 , 4, 5; wherein the first spindle 20 is in the base 12, and a bevel-toothed power gear 21 is fixed to the assembly, and the end is set as a vertical processing end 30, and the vertical processing end 30 is used to install the chuck and the tool to perform vertical milling on the workpiece; another example Figure 3 , 6 7. The linkage gear set 50 is installed on one side of the base 12 which is relatively perpendicular to the first main shaft 20. The linkage gear set 50 includes a driven shaft 51 rotatably installed in the base 12, a first driven wheel 52 fixed to the driven shaft 51, and a second driven wheel 53. The first driven wheel 52 is bevel-toothed and is used to orthogonally drive the power gear 21 of the first main shaft 20. Therefore, when the first main shaft 20 rotates, the power gear 21 is used to orthogonally drive the first driven wheel 52 to drive the driven shaft 51 to rotate;

[0060] Please see again Figure 3 , 8 As shown in Figures 9 and 10, the base 12 is parallel to the adjacent linkage gear set 50, and the rotatable second spindle 40 is installed. The second spindle 40 is fixed with a driving wheel 41 for engaging the second driven wheel 53, and a ring seat 43. The end of the second spindle 40 is set as a horizontal processing end 35, and the horizontal processing end 35 is used to install a chuck and a tool to perform end milling on the workpiece; wherein the driving wheel 41 is as shown in Figure 10. Figure 8 , 9 As shown in FIG. 10 , the driving wheel 41 comprises an axle body 411, a stop ring 44, and at least one key piece 413 fixed to the second main shaft 40. A through hole 414 is axially provided throughout the driving wheel 41, and the driving wheel 41 is fixed to the outer side of the second main shaft 40 in a protruding shape through the key piece 413, so that the cross section of the second main shaft 40 at the key piece 413 is non-circular, and the concave-convex shape of the inner hole wall of the through hole 414 of the driving wheel 41 completely corresponds to the cross section of the corresponding key piece 413 of the second main shaft 40, so that the driving wheel 41 can rotate with the second main shaft 40, and the driving wheel 41 can be axially displaced along the second main shaft 40 when being pushed by an external force;

[0061] In addition, the above-mentioned ring seat 43 is rotatably sleeved on the outer side of the shaft body 411 of the driving wheel. For this purpose, the inner diameter of the ring seat 43 is larger than the outer diameter of the shaft body 411, and a bearing 431 is sleeved between the inner side surface of the ring seat 43 and the outer side surface of the shaft body 411, so that when the driving wheel 41 and the shaft body 411 rotate with the second main shaft 40, the ring seat 43 will not rotate through the bearing 431. The ring seat 43 is also cut with a plane at a place on the outer wall to form a protruding rib 432 thereon, so that the ring seat 43 and the driving wheel 41 will not easily move axially. In addition, a stop ring 44 is sleeved on the outer side of one end of the shaft body 411 to provide auxiliary positioning adjacent to the ring seat 43;

[0062] The clutch 60 is as follows Fig. 9 , 10As shown in FIG. 11 , the clutch 60 includes a shift block 61, a shift control shaft 62, a spring 65, and a positioning seat 66, wherein the shift block 61 includes a base 611, an arm 613 vertically extending from one side of the base 611, the base 611 is provided with a slot 612 corresponding to the position facing the ring seat 43, the arm 613 is traversed with a through hole 614, the shift block 61 is engaged with the protruding rib 432 of the ring seat 43 by the slot 612, and the base 611 is screwed and fixed to the outer plane of the ring seat 43, and a sleeve 615 is fixed to the through hole 614 of the shift block 61;

[0063] The control shaft 62 is a shaft body, and the two ends are respectively a first end 621 and a second end 624. A shoulder 622 and a body 623 are arranged between the first end 621 and the second end 624. The outer diameter of the shoulder 622 is larger than that of the body 623. The first end 621 is locked with at least one ring 6211 at the end of the through hole 614 extending out of the shift block 61. The other end of the first end 621 extending out of the through hole 614 can be blocked against the corresponding surface of the shift block 61 through the shoulder 622 as the first end 621 passes through the through hole 614, so that the shoulder 622 provides a blocking and positioning function. A spring 65 is sleeved on the body 623, so that one end of the spring 65 is blocked against the shoulder 622. After the spring 65 is sleeved, a directional pin 63 is transversely assembled and fixed on the body 623. The two ends of the directional pin 63 protrude from the outside of the body 623, and the second end 624 passes through the positioning seat 66.

[0064] The positioning seat 66 is as follows Figure 1 As shown, it is installed and fixed on the outer side of the base 12. The positioning seat 66 is a convex seat body, and a through hole 661 is penetrated through the center. The through hole 661 can allow the body 623 of the dial control shaft 62 to axially move. The axial part of one end of the positioning seat 66 is a column 662. The column 662 is provided with a slide groove 67 connected with the through hole 661 on the two side walls that pass through the central axis and form a relative angle. The directional pin 63 can be displaced along the track of the slide groove 67. The positioning seat 66 is provided with two slots 663 at corresponding angles at the end surface of the column 662, corresponding to the slot 67 at a 90-degree angle interval. The directional pin 63 is displaced out along the axial direction of the slide groove 67 with the dial control shaft 62, and the dial control shaft 62 is turned 90 degrees, so that the directional pin 63 is clamped in the slot 663 for positioning;

[0065] The base 12 is used to house the clutch 60 assembly. Figure 3 , 9 As shown in FIG. 11, a side hole 13 is provided on an outer side of the base 12, and a cover 68 and a cover sheet 682 are provided at the side hole. The cover 68 is hollow and a fixing hole 681 is provided on one side. Figure 1 , 3As shown in FIG. 9 , the cover body 68 is covered and screwed to the outer side of the side hole 13 of the base 12, so that the dial block 61, the dial control shaft 62 and the spring 65 are hidden in the cover body 68, and the body 623 and the second end 624 are extended through the fixing hole 681 of the cover body 68, and the positioning seat 66 is on the outside of the cover body 68, so that the through hole 661 is aligned with the second end 624 of the dial control shaft 62 and is inserted, and the directional pin 63 is shifted with the dial control shaft 62 to align with the slide groove 67, so that the spring 65 is in the cover body 68, and the two ends are respectively received by the shoulder 622 of the dial control shaft 62 and the positioning seat 6 6, the positioning seat 66 is then screwed and fixed to the outer side of the fixing hole 681 of the cover body 68 to form a positioning, and the second end 624 of the dial control shaft 62 extends out along the through hole 661 of the positioning seat 66, forming the other end of the spring 65 different from the shoulder 622 to press against the corresponding end surface of the positioning seat 66, and the second end 624 is sleeved with a control seat 625 with an outer diameter larger than that of the dial control shaft 62 at one end of the second end 624 extending out of the positioning seat 66, and a fixing pin 64 is riveted to the second end 624 on the outer side of the control seat 625, so that the control seat 625 is fixedly connected to the dial control shaft 62, so that Figure 1 As shown, when the clutch 60 is in position, the control seat 625 can be pulled to actuate the shift control shaft 62 , and then the shift block 61 and the driving wheel 41 are linked.

[0066] Please see Figure 2 , 3 9, when the end milling of the workpiece is to be carried out at the horizontal processing end 35, the end milling chuck and the tool are installed at the horizontal processing end 35, and the shift block 61 of the clutch 60 clamps the ring seat 43, and the driving wheel 41 is still kept meshing with the second driven wheel 53 of the linkage gear set 50; therefore, the driving power source is driven to drive the first main shaft 20 to rotate, and then the power gear 21 of the first main shaft 20 rotates, and drives the first driven wheel 52 of the linkage gear set 50 through meshing, and then the driven shaft 51, The second driven wheel 53 rotates, and the second driven wheel 53 can mesh and drive the driving wheel 41 to rotate, and then the second spindle 40 and its end surface processing tool rotate, so as to meet the requirements of end surface processing of the workpiece; since a bearing 431 is installed between the ring seat 43 and the driving wheel 41, and a key 413 is engaged between the driving wheel 41 and the second spindle 40, the driving wheel 41 can rotate with the second spindle 40 without interfering with the shifting block 61 and the shifting control shaft 62, so that the shifting block 61 and the shifting control shaft 62 remain stationary;

[0067] On the contrary, if Figure 2 , 3 5, if a vertical milling chuck and its related tools are installed at the vertical processing end 30 to perform vertical milling processing on a workpiece, the present invention can control the clutch 60 to disengage and link the gear set 50 from the gear meshing state without wasting the power transmitted from the first spindle 20 to the second spindle 40; please refer to Figure 1 , 12As shown in Figures 13, the user pulls the control seat 625 by hand on the outer side of the cover body 68 of the base body 12 to pull the dial control shaft 62 axially. At the same time, the directional pin 63 follows the dial control shaft 62 and moves along the track of the slide groove 67 of the positioning seat 66. The dial control shaft 62 overcomes and compresses the elasticity of the spring 65, and more parts of the body 623 are pulled out of the positioning seat 66. The force applied to the dial control shaft 62 causes the dial block 61 to be clamped by the ring seat 43. Therefore, the axial displacement of the dial control shaft 62 can synchronously link the drive wheel 41 to axially move along the key member 413, so that the drive wheel 41 is out of the state of being engaged with the second driven wheel 53 of the linkage gear set 50. At this time, as shown in Figures 14 and 15, the dial control shaft 62 is not engaged with the second driven wheel 53 of the linkage gear set 50. Figure 1 , 14 As shown in FIG. 15 , the directional pin 63 is pulled out of the slide slot 67. Fig. 9 , 10 The shaft sleeve 615 is inserted between the through hole 614 of the shift block 61 and the outer side surface of the first end 621 of the shift control shaft 62. Therefore, when the shift control shaft 62 is rotated by force, it can rotate in the shaft sleeve 615, thereby rotating the control seat 625 by 90 degrees, causing the directional pin 63 to stagger the original position of the slide groove 67, and then loosening the control seat 625 to allow the directional pin 63 to be positioned in the concave and convex position in the missing groove 663, maintaining the drive wheel 41 and the linkage gear set 50 out of meshing state; in this way, the second main shaft 40 is not affected by the power of the linkage gear set 50, the first main shaft 20 rotates, the power gear 21 rotates accordingly, and meshes with the first driven wheel 52 to rotate the driven shaft 51, and the second driven wheel 53 is in an idling state because it is not meshed with the driving wheel 41, and will not drive the second main shaft 40 and its driving wheel 41 to rotate, and the second main shaft 40 and its horizontal processing end 35 will not rotate, thereby avoiding the power loss of the first main shaft 20 driving the second main shaft 40;

[0068] If the driving wheel 41 is to be restored to its original state of being engaged with the interlocking gear set 50, the control seat 625 can be pulled again and turned 90 degrees to align the directional pin 63 with the slide groove 67. The elastic restoring force of the spring 65 can drive the control shaft 62 to move axially along the through hole 661 of the positioning seat 66 and the directional pin 63 along the slide groove 67 until the control seat 625 is positioned against the end surface of the column portion 662 of the positioning seat 66, so that the driving wheel 41 can be re-engaged with the second driven wheel 53 of the interlocking gear set 50.

[0069] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
