[0052] The starter intake shell drilling machining center and its machining method provided by the embodiments of the present application will be described in detail below with reference to the drawings, through specific embodiments and their application scenarios.

[0053] Embodiment 1:

[0054] As Figures 1 to 5 shown in the figure, the embodiment of the application provides a starter air inlet shell drilling machining center, which comprises a machine base 1, a drilling device 2 and a clamp 3. The clamp 3 comprises a rotating table 31 which is driven by a motor and is rotatably installed on the machine base 1 and is provided with a plurality of through grooves 32. A plurality of supporting tables 33 are controlled by a lifting control device 34 and are respectively and liftably installed in the through grooves 32. A plurality of vertical plates 35 are respectively and symmetrically arranged at both ends of the surface of each supporting table 33 and are respectively provided with a sliding groove 36 at the bottom. A plurality of clamping plates 37 are respectively and slidably installed in each sliding groove 36, the outer end of the bottom of each clamping plate 37 is inclined, the middle part of each clamping plate 37 is provided with a triangular groove 38, and the outer end surface of each triangular groove 38 is inclined upward. A plurality of reset members 39 are arranged on the table surface of the rotating table 31 and are respectively located on both sides of each through groove 32 and correspond to each clamping plate 37. When the lifting device controls the supporting table 33 to rise / lower, the outer end of each reset member 39 / every clamping plate 37 is in sliding cooperation with the inner peripheral wall of the corresponding triangular groove 38 / through groove 32, and the control of each clamping plate 37 sliding outward / inward of the supporting table 33 is realized.

[0055] In the embodiment of the application, the starter air inlet shell which has not been drilled is placed on the supporting table 33 which has been raised, then the motor drives the rotating table 31 to rotate, the lifting control device 34 simultaneously controls the supporting table 33 carrying the starter air inlet shell which has not been drilled to lower, each clamping plate 37 enters the through groove 32 as the supporting table 33 lowers, the outer end inclined surface of each clamping plate 37 is in contact with the top of the through groove 32 and is pushed inward of the supporting table 33 by the peripheral wall of the through groove 32, so that the starter air inlet shell which has not been drilled is clamped. When the starter air inlet shell which has not been drilled is moved to the position below the drilling device 2, the motor stops running, the drilling device 2 operates to drill the starter air inlet shell which has not been drilled, after the drilling operation is completed, the motor drives the rotating table 31 to rotate, the lifting control device 34 simultaneously controls the supporting table 33 carrying the starter air inlet shell which has not been drilled to rise, each clamping plate 37 gradually separates from the through groove 32 as the supporting table 33 rises, and cooperates with the reset member 39 until the supporting table 33 rises to the highest position, each clamping plate 37 completely releases the clamping of the starter air inlet shell, and the worker can take off the starter air inlet shell which has completed the drilling operation from the supporting plate and replace a new starter air inlet shell which has not been drilled on the supporting plate.

[0056] Embodiment 2:

[0057] As Figure 2 and Figure 5As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the reset member 39 includes a top groove 391, which is disposed on the top surface of the vertical plate 35; a horizontal plate 392, which can extend into the top groove 391, one end of which is fixed to the top surface of the rotary table 31 by a support plate 393, and the other end of which is fixed to the bottom of a reset post 394 that can slide and cooperate with the outer side of the triangular groove 38.

[0058] Preferably, the cross-sections of the support platform 33 and the through groove 32 are both circular, and the top groove 391, the horizontal plate 392, the support plate 393 and the reset column 394 are all arc-shaped and concentric with the support platform 33.

[0059] In this embodiment of the application, due to the above-described structure, the positions of the pair of horizontal plates 392 and the pair of reset posts 394 remain unchanged. When the support platform 33 rises, the corresponding pair of clamping plates 37 and the pair of vertical plates 35 also rise simultaneously. Each reset post 394 gradually inserts into the corresponding side groove and triangular groove 38 and abuts against the inclined surface located at the outer end of the corresponding triangular groove 38. As the support platform 33 continues to rise, each clamping plate 37 moves closer to the corresponding horizontal plate 392, and each reset post 394 goes deeper into the corresponding triangular groove 38. In this way, it can cooperate with the corresponding triangular groove 38 to push the corresponding clamping plate 37 outward from the corresponding support platform 33 and release the fixation of the starter intake housing.

[0060] It should be noted that since each clamping plate 37 has an inclined surface at its outer bottom, and each clamping plate 37 only begins to slide outward toward the corresponding support 33 when it is close to the upper surface of the rotating table 31, due to the existence of the aforementioned inclined surface, each clamping plate 37 will not interfere with the peripheral wall of the through groove 32 during the outward sliding process.

[0061] Example 3:

[0062] like Figures 2 to 5 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the lifting control device 34 includes an arc groove, which is arranged around the inner cavity of the base 1, including a sinking section 341 and a rising section 342 connected end to end, with the rising section 342 being higher than the sinking section 341; a plurality of connecting rods 343 are respectively fixed on the bottom surface of each support platform 33, and a transmission column 344 that slides with the arc groove is fixed at the lower end.

[0063] Further, it also includes several overturning control grooves 4, which are respectively arranged on the peripheral wall of each through groove 32, and include several L-shaped grooves composed of upright sections 41, inclined sections 42 and inclined guide surfaces 43. The top end of each upright section 41 is open, and one end of the inclined section 42 is in communication with the lower end of the upright section 41, and the other end is in communication with the middle part of the upright section 41 of the adjacent L-shaped groove. Several transmission sliding blocks 44 are respectively arranged on the peripheral wall of each support table 33 and are in sliding cooperation with the corresponding L-shaped grooves. The reciprocating lifting mechanism 5 is in cooperation with the transmission column 344 of the corresponding drilling device 2, and is used for controlling the lifting of the corresponding support table 33. Each inclined guide surface 43 is arranged outside the corner of the corresponding L-shaped groove.

[0064] Further, the number of L-shaped grooves in the overturning control groove 4 depends on the number of mounting holes on the starter air intake shell.

[0065] In this embodiment of the present application, due to the adoption of the above structure, with the rotation of the rotating table 31, each transmission column 344 on each connecting rod 343 slides in the ascending section 342 and the descending section. When it slides to the ascending section 342, the corresponding connecting rod 343 and the support table 33 are lifted. At this time, each transmission sliding block 44 slides to the top of the corresponding upright section 41 of the L-shaped groove. In this process, each reset column 394 extends into the corresponding triangular groove 38, so that the corresponding pair of clamping plates 37 slides outwardly to the support table 33. When each transmission column 344 slides to the sinking section 341, each connecting rod 343 pulls the corresponding support table 33 to descend. At this time, each clamping plate 37 completely enters the corresponding through groove 32, and the clamping and fixing of the starter air intake shell are completed. Each transmission sliding block 44 is located in the middle part of the corresponding upright section 41 of the L-shaped groove. The ascending section 342 is away from the drilling device 2, and the reciprocating lifting mechanism 5 is located below the drilling device 2. When the starter air intake shell needs to be rotated below the drilling device 2, the reciprocating lifting mechanism 5 cooperates with the transmission column 344 of the corresponding drilling device 2 at this time, controls a part of the sinking section 341 to descend together with the transmission column 344, so that each transmission sliding block 344 slides from the middle part of the corresponding upright section 41 to the inclined section 42, and then slides along the inclined guide surface 43 to the lower end of the inclined guide surface 43. Then the reciprocating lifting mechanism 5 controls a part of the sinking section 341 to ascend together with the transmission column 344 located therein, so that the transmission sliding block 344 cooperates with the top surface of the inclined section 42 and slides to the other end of the inclined section 42, until it enters the middle part of the upright section 41 connected to the other end of the inclined section 42. The inclined section 42 is spirally arranged on the inner peripheral wall of the through groove 32. Therefore, in this process, the support table 33 rotates while ascending. When each transmission sliding block 344 enters the middle part of another upright section 41, the reciprocating lifting mechanism 5 also stops running. When it runs again, it controls each transmission sliding block 344 to slide downward, so that each clamping plate 37 cannot be separated from the corresponding through groove 32, and can keep clamping the starter air intake shell. At the same time, the rotation of the starter air intake shell is completed, so that the position of the starter air intake shell which needs to be drilled is adjusted to be directly below the drill bit of the drilling device 2.

[0066] It should be noted that the positions on the starter intake housing that need to be drilled can be on the same edge of a circle, the center of which is the same as the center of the support 33. The number of L-grooves is set according to the number of positions on the starter intake housing that need to be drilled. The length of the inclined section 42 of the corresponding L-grooves can be adjusted according to the angle of the central angle between each drilling position, so that the angle of the central angle made by the two ends of the corresponding inclined section 42 with the axis of the through groove 32 is equal to that of the L-grooves. In this way, each time the support 33 rises and falls, the next position on the starter intake housing that needs to be drilled can be rotated to directly below the drill bit of the drilling device 2.

[0067] Example 4:

[0068] like Figures 1 to 5 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the reciprocating lifting mechanism 5 includes a lifting groove 51, which is vertically arranged in the inner cavity of the base 1; a lifting block 52, which is slidably installed in the lifting groove 51, and a connecting rod 53 is hinged to the bottom; a cylinder 54, which is horizontally fixed at the bottom of the inner cavity of the base 1, and its piston rod is hinged to the other end of the connecting rod 53, and a portion of the sinking section 341 is arranged on the inner side wall of the lifting block 52.

[0069] Furthermore, it also includes several circular rings 6, which are fixedly mounted on the bottom surface of each support platform 33, with their outer peripheral walls slidingly engaging with the inner peripheral walls of the corresponding through grooves 32.

[0070] A machining method for a starter intake housing drilling machining center is also disclosed, including the following steps:

[0071] S1. Place the starter intake housing on the support platform 33. The motor drives the rotary table 31 to rotate. The corresponding transmission column 344 enters the sinking section 341. The support platform 33 descends, a pair of clamping plates 37 close, and the transmission slider 44 moves to the middle of the upright section 41 to complete the fixation of the starter intake housing.

[0072] S2. The starter intake housing to be fixed is moved to below the drilling device 2, and the motor stops running;

[0073] S3, Drilling device 2 is activated to perform the first drilling on the starter air intake housing, and after completion, proceed to S4;

[0074] S4, cylinder 54 is running, piston rod retracts and then extends, pulling lifting block 52, connecting rod 343 and support platform 33 to descend and then rise through connecting rod 53. Transmission slider 44 descends from the middle of the vertical section 41 of L groove to the bottom of inclined guide surface 43, then rises and slides from inclined section 42 to the vertical section 41 of adjacent L groove, so that the other part of the starter air intake housing that needs to be drilled is aligned with drilling device 2.

[0075] S5, repeat S3-S4 until the drilling of all mounting holes on the starter intake shell is completed, and proceed to S6;

[0076] S6, the motor drives the rotating table 31 to rotate, so that the drilled starter intake shell is away from the drilling device 2, the corresponding transmission sliding block 44 enters the ascending section 342, the supporting table 33 and the pair of clamping plates 37 ascend, the corresponding reset column 394 extends into the triangular groove 38, and the pair of clamping plates 37 are separated;

[0077] S7, the drilled starter intake shell is taken out from the supporting table 33, and returns to S1.

[0078] In this embodiment of the present application, since the above structure is adopted, when the transmission column 344 corresponding to the drilling device 2 needs to be reciprocatingly lifted and lowered, the cylinder 54 acts, the piston rod thereof is first retracted and then extended, the lifting block 52 is first lowered and then lifted in the lifting groove 51 by the connecting rod 53, and when the lifting block 52 is lifted to the highest point, it is limited by the bottom surface of the rotating table 31 and cannot be lifted any more, so that each transmission sliding block 44 cannot enter the upper part of the corresponding upright section 41 when it is below the drilling device 2, and each clamping plate 37 can keep clamping the starter intake shell, and the setting of each circular ring sleeve 6 can improve the stability of the lifting of each supporting table 33 in the corresponding through groove 32.

[0079] It should be noted that in this document, the terms "comprise", "comprising", or any other variant thereof are intended to cover a non-exclusive inclusion, so that a process, method, article, or apparatus that includes a list of elements not only includes those elements, but also includes other elements not expressly listed, or inherent to such process, method, article, or apparatus.
