Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically a multi-dimensional adjustment mechanism for a power head. Background Technology

[0002] Machining is inseparable from CNC lathes. Currently, in machining processes, the power head basically operates at zero degrees. This machining method cannot meet the needs of machining irregularly shaped workpieces, meaning the angle cannot be adjusted. There is currently a power head on the market with adjustable angles (patent publication number: CN220562985U, patent name: Universal Turning and Milling Composite Power Head). This patent's technical solution allows for the oscillation adjustment of the tool head, meaning different heights can be adjusted. However, the applicant still discovered a minor problem during the machining process: the existing technical solution cannot adjust rotation, meaning it cannot offset; it can only machine in the same vertical direction. Currently, the adjustable angle power heads on the market are generally made as separate axial or longitudinal power tool holders. Further, they can be tool holders that can rotate ±90 degrees around an axis, commonly known as universal power tool holders. Although they are called universal, they can only rotate around a single axis within a cross section, and the machining area is extremely limited. Therefore, the applicant needs to design a new technical solution to address the shortcomings of the existing technology and solve the problems existing in the existing technology. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a multi-dimensional adjustment mechanism for a power head. By incorporating an adjustable mechanism in the middle, the power head can be horizontally adjusted to meet the processing needs of different products.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-dimensional adjustment mechanism for a power head, comprising a power head body and a tool mounting base. The power head body is composed of an upper housing and a lower housing, with a drive shaft disposed between the upper housing and the lower housing. A bevel gear assembly is disposed at the output end of the drive shaft, and a horizontal rotation mechanism is disposed between the upper housing and the lower housing, thereby enabling the power head body to rotate.

[0005] Furthermore, the upper part of the upper shell is provided with a water inlet hole, and the other end of the water inlet hole is provided with a water outlet hole, and a water flow channel is provided between the water inlet hole and the water outlet hole.

[0006] Furthermore, the top of the upper housing is provided with several limiting blocks, which are fixed to the upper housing by bolts.

[0007] Furthermore, the horizontal rotation mechanism includes a locking screw, a positioning groove, and a fixed dial. The positioning groove is located on the outer surface of the lower housing, and the locking screw is located inside the positioning groove. The upper housing and the lower housing are detachably connected by the locking screw. The fixed dial is located on one side of the upper housing and is fixedly connected to the upper housing by a screw.

[0008] Furthermore, the bevel gear assembly includes a first bevel gear, a second bevel gear, a third bevel gear, and a fourth bevel gear. A central shaft perpendicular to the drive shaft is fixed inside the lower housing. The first bevel gear is located at the output end of the drive shaft. The third bevel gear is located on the central shaft. The third bevel gear is connected to a bevel gear shaft integrally formed therewith. The bevel gear shaft is rotatably located on the central shaft. The second bevel gear is located on the bevel gear shaft. The first bevel gear and the second bevel gear mesh with each other.

[0009] Furthermore, the lower housing is provided with a linkage component and a clearance groove, which is used for the upper part of the linkage component to be connected. The tool mounting seat is located inside the linkage component, and the fourth bevel gear sleeve is adapted to the outer surface of the tool mounting seat. The third bevel gear and the fourth bevel gear mesh with each other.

[0010] Furthermore, a swing mechanism is provided between the linkage and the lower housing, and the linkage and the lower housing swing up and down through the swing mechanism.

[0011] Furthermore, the up-and-down swing mechanism includes a connecting shaft, a circular dial, and a gear. The gear is fitted onto the outer surface of the connecting shaft. Several through holes are provided on the outer side of the circular dial. A water nozzle is provided on one side of each through hole. A second locking screw is provided inside each through hole. A screw hole is provided on the surface of the linkage component. The screw hole corresponds to the second locking screw, and the second locking screw is connected and fixed by passing through the second locking screw and the screw hole.

[0012] Furthermore, the locking screw can be adjusted and fixed within the space of the positioning groove. Beneficial effects

[0013] This invention provides a multi-dimensional adjustment mechanism for a power head. Compared with the prior art, it has the following advantages: By incorporating a horizontal rotation mechanism, the power head body can rotate horizontally, and the power head can also swing up and down. This adds a horizontal rotation mechanism to existing technologies. By unscrewing the locking screw, the angle can be adjusted according to the fixed scale. The locking screw moves within the positioning groove, and the upper and lower housings are detachably connected via the locking screw. Therefore, when adjusting the angle, moving the locking screw will cause the upper and lower housings to rotate accordingly. When the desired position is reached, tightening the screw is sufficient. This patent allows for both vertical and horizontal rotation, satisfying the processing of irregularly shaped workpieces. The fixed scale design also allows for accurate measurement of the rotation angle, ensuring processing precision.

[0014] The rotating mechanism in this patent significantly expands the processing area, freeing up the processing environment. This rotating mechanism also rotates around another axis, which is perpendicular to the axis that rotates ±90 degrees. This creates a five-axis-like processing effect in space, greatly expanding the processing capabilities of general milling and turning machines. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6 This utility model provides a technical solution: a multi-dimensional adjustment mechanism for a power head. It includes a power head body 1 and a tool mounting base 2. The power head body 1 consists of an upper housing 11 and a lower housing 12. A drive shaft 3 is disposed between the upper housing 11 and the lower housing 12. A bevel gear set 4 is disposed at the output end of the drive shaft 3. A horizontal rotation mechanism 5 is disposed between the upper housing 11 and the lower housing 12, enabling the power head body 1 to rotate. By setting the horizontal rotation mechanism 5, the power head body 1 can rotate horizontally, and the power head can also swing up and down. This adds a horizontal rotation mechanism 5 to the existing technology. By unscrewing the locking screw 51, the angle is adjusted according to the fixed scale 53. The locking screw 51 moves within the positioning groove 52. Since the upper housing 11 and the lower housing 12 are detachably connected via the locking screw 51, when adjusting the angle, the upper and lower housings rotate accordingly as the locking screw 51 moves. When the desired position is reached, the screw 51 is tightened. It should be noted that this patent allows for both vertical and horizontal rotation, accommodating the processing of irregularly shaped workpieces. Furthermore, the design of the fixed dial ensures accurate measurement of the rotation angle, guaranteeing processing precision.

[0020] The upper part of the upper shell 11 is provided with a water inlet hole 111, and the other end of the water inlet hole 111 is provided with a water outlet hole 112. A water flow channel is provided between the water inlet hole 111 and the water outlet hole 112.

[0021] The top of the upper housing 11 is also provided with several limiting blocks 113, which are fixed to the upper housing 11 by bolts 1131. The two symmetrical limiting blocks 113 on the left and right sides can make the power head and the power turret mounting holes concentric, thereby improving the machining accuracy.

[0022] The horizontal rotation mechanism 5 includes a locking screw 51, a positioning groove 52, and a fixed scale 53. The positioning groove 52 is located on the outer surface of the lower housing 12, and the locking screw 51 is located inside the positioning groove 52. The upper housing 11 and the lower housing 12 are detachably connected by the locking screw 51. The fixed scale 53 is located at one end of the outer side of the upper housing 11 and is fixedly connected to the upper housing 11 by screws. There are four locking screws 51 on the outer surface of the lower housing, and two positioning grooves 52. When angle adjustment is required, two symmetrical locking screws 51 must be turned out simultaneously for adjustment.

[0023] The bevel gear assembly 4 includes a first bevel gear 41, a second bevel gear 42, a third bevel gear 43, and a fourth bevel gear 44. A central shaft 121, perpendicular to the drive shaft 3, is fixed inside the lower housing 12. The first bevel gear 41 is located at the output end of the drive shaft 3, and the third bevel gear 43 is located on the central shaft 121. The third bevel gear 43 is connected to a bevel gear shaft 431 integrally formed therewith. The bevel gear shaft 431 is rotatably mounted on the central shaft 121. The second bevel gear 42 is located on the bevel gear shaft 431, and the first bevel gear 41 and the second bevel gear 42 mesh with each other. By integrally forming the third bevel gear 43 with the bevel gear shaft 431, the number of parts is reduced, and the central shaft 121 simultaneously supports both the third bevel gear 43 and the bevel gear shaft 431, achieving multiple uses from a single shaft.

[0024] The lower housing 12 is provided with a linkage 122 and a clearance groove 123. The clearance groove 123 is used for the upper part of the linkage 122 to be connected. The tool mounting seat 2 is located inside the linkage 122. The fourth bevel tooth 44 is fitted onto the outer surface of the tool mounting seat 2. The third bevel tooth 43 and the fourth bevel tooth 44 mesh with each other. The first bevel gear 41 and the second bevel gear 42 mesh with each other. Since the first bevel gear 41 is located at the output end of the drive shaft 3 and the second bevel gear 42 is located on the bevel gear shaft 431, the first bevel gear 41 transmits the driving force to the second bevel gear 42, and the second bevel gear 42 transmits the driving force to the bevel gear shaft 431. The third bevel gear 43 is integrally formed with the bevel gear shaft 431, so when the bevel gear shaft 431 rotates, the third bevel gear 43 also rotates. Since the fourth bevel gear 44 is fitted on the outer surface of the power mounting base 2 and meshes with the third bevel gear 43, that is, the first bevel gear 41 transmits the driving force to the second bevel gear 42, the second bevel gear 42 transmits the driving force to the bevel gear shaft 431, the bevel gear shaft 431 transmits the driving force to the third bevel gear 43, and the third bevel gear 43 transmits the driving force to the fourth bevel gear 44, thereby driving the power head, dispersing the load pressure of the single-stage gear, and reducing wear.

[0025] A swing mechanism 6 is provided between the linkage 122 and the lower housing 12, and the linkage 122 and the lower housing 12 swing up and down through the swing mechanism 6. The swing mechanism 6 drives the angle of the adjustable tool mounting seat 2, thereby changing the direction of tool processing to adapt to various processing needs.

[0026] Please read Figure 7 As shown; the up-and-down swing mechanism 6 includes a connecting shaft 61, a circular dial 62 and a gear 63. The gear 63 is fitted onto the outer surface of the connecting shaft 61. The outer side of the circular dial 62 is provided with several through holes 621. A water nozzle 64 is provided on one side of the through hole 621. A locking screw 622 is provided inside the through hole 621. The connecting shaft 61 coincides with the central axis of the central shaft 121. Two through holes 621 are symmetrically arranged next to the water nozzle 64. The tool mounting seat 2 is fixed by tightening the second locking screw 622. When the angle needs to be adjusted, one of the second locking screws 622 is unscrewed, and the required angle is adjusted according to the circular scale 62. Then the second locking screw 622 is tightened. Three through holes are arranged in a triangle around the water nozzle 64. These three through holes are used to fix the gear 63 and the circular scale 62. The surface of the linkage 122 is provided with screw holes 1220, which correspond to the second locking screw 622. The second locking screw 622 is connected and fixed by passing through the second locking screw 622 and the screw hole 1220. In this way, the angle of the tool mounting seat 2 can be adjusted.

[0027] Please read Figure 8 As shown; the locking screw 51 can be adjusted and moved within the space of the positioning groove 52. After being moved to a suitable angle, the upper housing 11 and the lower housing 12 are tightly fixed by tightening the locking screw 51.

[0028] Working principle; The power head 1 is mounted on the outer surface of the turret; this is a current machining technology. After installing the power head 1 to the turret... The turret is equipped with a power output mechanism, allowing the power head's rotating shaft to receive power. As the shaft rotates, the first bevel gear 41 rotates accordingly. The first bevel gear 41 and the second bevel gear 42 mesh with each other. Since the first bevel gear 41 is located at the output end of the drive shaft 3, and the second bevel gear 42 is located on the bevel gear shaft 431, the first bevel gear 41 transmits driving force to the second bevel gear 42, and the second bevel gear 42 transmits driving force to the bevel gear shaft 431. The third bevel gear 43 is integrally formed with the bevel gear shaft 431, so when the bevel gear shaft 431 rotates, the third bevel gear 43 also rotates. Because the fourth bevel gear 44 fits onto the outer surface of the power mounting base 2 and meshes with the third bevel gear 43, the first bevel gear 41 transmits driving force to the second bevel gear 42, the second bevel gear 42 transmits driving force to the bevel gear shaft 431, the bevel gear shaft 431 transmits driving force to the third bevel gear 43, and the third bevel gear 43 transmits driving force to the fourth bevel gear 44, thus driving the power head. Additionally, two symmetrical positioning grooves 52 are arranged on the outer surface of the lower housing 12. The positioning grooves 52 contain locking screws 51. The upper housing 11 has through holes corresponding to the locking screws 51. Therefore, the upper housing 11 and the lower housing 12 are detachably connected by the locking screws 51. After unscrewing the two symmetrical locking screws 51 and loosening the locking screws 51 and the upper housing 11 and the lower housing 12, the operator can adjust the angle according to the fixed scale 53. When the upper housing 11 and the lower housing 12 are rotated to the required angle, the locking screws 51 are tightened to fix the upper housing 11 and the lower housing 12, thus achieving the adjustment of the horizontal angle.

[0029] It should be noted that the up-and-down swing mechanism 6 is prior art, therefore no detailed illustration of the prior art is provided. The technical solution of this patent mainly highlights the adjustment settings of the horizontal rotation mechanism 6.
