Description

Technical Field

[0001] The utility model belongs to the technical field of valve block drilling positioning, in particular to a valve block positioning switching device. Background Art

[0002] When processing valve blocks, it is necessary to cut smaller metal blocks from large blocks of raw materials, and then drill holes in the metal blocks. When drilling, it is necessary to first drill small holes in the metal blocks, and then expand the small holes. When drilling small holes, the metal block can be directly fixed under the drilling machine for drilling, or the metal block can be fixed on a drilling alignment tooling, and the tooling has corresponding alignment holes. The tooling is fixed under the drilling machine, and then the drill bit is inserted into the alignment hole for drilling. Compared with direct drilling, the use of drilling alignment tooling can effectively avoid drill bit deviation during drilling. However, different types of valve blocks require different drilling positions. When switching the type of valve block to be processed, it is necessary to switch and fix different drilling alignment tooling again, which is time-consuming and affects the efficiency of valve block processing, and needs further improvement.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0025] The present application embodiment provides a valve block positioning switching device, such as Figure 1-Figure 5 As shown, it includes a rotating drum 1, a rotating disk 2, a rectangular alignment frame 3, a rotating mechanism, etc.

[0026] Specifically, the turntable 2 is coaxially attached to the outside of the drum 1, and there are multiple rectangular alignment frames 3, which are arranged above the turntable 2 in a circular array, and the rectangular alignment frames 3 are connected to the drum 1 along the axial sliding of the drum 1, and the opening of the rectangular alignment frames 3 is arranged toward the turntable 2. Alignment holes 301 are provided on the top surfaces of the rectangular alignment frames 3, and the number and / or position of the alignment holes 301 of each rectangular alignment frame 3 are different, which are used to drill and position the valve blocks 8 with different requirements for the position and / or number of drilling holes. A first push rod 302 is penetrated at one end of the rectangular alignment frame 3 away from the drum 1, and a second push rod 303 is penetrated at one side of the rectangular alignment frame 3; a rotating mechanism is arranged below the turntable 2, which is connected to the drum 1, and is used to drive the drum 1 to rotate.

[0027] During actual use, the device is placed under the drilling machine, and the rotating drum 1 is controlled to rotate by the rotating mechanism so that the rectangular alignment frame 3 to be used is rotated to the stacking rack facing the valve block 8 to be processed, and then the rectangular alignment frame 3 is lifted up, and the valve block 8 to be processed is placed under the rectangular alignment frame 3, and then the rectangular alignment frame 3 is lowered, and the valve block 8 to be processed is pushed by the first push rod 302 and the second push rod 303 to align it with the alignment hole 301, and then the rotating drum 1 is controlled to rotate by the rotating mechanism so that the rectangular alignment frame 3 is rotated to the bottom of the drilling machine, and the drill bit is controlled to extend into the alignment hole 301 of the rectangular alignment frame 3 to start drilling.

[0028] Specifically, in one embodiment, see Figure 1 , Figure 3 , Figure 4 , multiple rectangular alignment frames 3 are respectively arranged between multiple pairs of vertical plates 4, the vertical plates 4 are connected to the rotating drum 1, and first sliding grooves 401 are symmetrically opened on multiple pairs of vertical plates 4. First sliders 304 are opened on both sides of multiple rectangular alignment frames 3, and the first sliders 304 are slidably connected in the sliding grooves. A second sliding groove 402 is opened on a vertical plate 4 on one side of the rectangular alignment frame 3, and the second push rod 303 is in the second sliding groove 402. The rectangular alignment frame 3 slides up and down between the pair of vertical plates 4 to realize axial sliding connection relative to the rotating drum 1 along the rotating drum 1.

[0029] For details, see Figure 3 The rotating mechanism includes a support base 5, a motor 501, and a gear ring 502. The rotating drum 1 is rotatably arranged on the support base 5, and the gear ring 502 is sleeved on the rotating drum 1. The output shaft of the motor 501 is connected with a gear 503, and the gear 503 is meshed with the gear ring 502. The motor 501 is fixed to the support base 5. The number of teeth of the gear 503 is less than that of the gear ring 502, that is, the motor 501 drives the large gear to rotate through the small gear. Compared with the motor 501 directly driving the rotating drum 1 to rotate, the load of the motor 501 can be reduced, and the speed of the rotating drum 1 can be easily controlled.

[0030] Preferably, see Figure 1A vertical rod 6 is connected inside the support seat 5, and the vertical rod 6 is axially the same as the rotating drum 1. The upper end of the vertical rod 6 is rotatably connected to a lifting mechanism 602 through a horizontal plate 601. The telescopic end of the lifting mechanism 602 is set toward the turntable 2, and the telescopic end of the lifting mechanism 602 is connected to a suction cup 603. When the telescopic end of the lifting mechanism 602 is retracted, the height of the suction cup 603 is higher than the height of the top of the vertical plate 4. When the telescopic end of the lifting mechanism 602 is pushed out and the rectangular alignment frame 3 is under the suction cup 603, the bottom of the suction cup 603 abuts against the top of the rectangular alignment frame 3. During actual use, the horizontal plate 601 is rotated to make the suction cup 603 face the area on the top of the rectangular alignment frame 3 that needs to be used and does not have the alignment hole 301. The lifting mechanism 602 is then controlled to drive the telescopic end to be pushed out so that the suction cup 603 abuts against and adsorbs the top of the rectangular alignment frame 3. The telescopic end of the lifting mechanism 602 is then controlled to retract, and the rectangular alignment frame 3 can be lifted upward, making it convenient to place the valve block 8 to be processed underneath it, without the need to manually lift the rectangular alignment frame 3.

[0031] Specifically, a screw rod can be selected as the first push rod 302 and the second push rod 303, and the screw rod is threadedly connected to the rectangular alignment frame 3, and the screw rod is moved toward the inside of the rectangular alignment frame 3 by rotating the screw rod. In another embodiment, refer to Figure 1 , Figure 5 A second pushing mechanism 701 is connected to one side of the support seat 5 through a support frame 7, and the telescopic direction of the telescopic end of the second pushing mechanism 701 is the same as the diameter of the rotating drum 1. A third pushing mechanism 703 is hinged to one side of the support frame 7 through a hinge rod 702, and the telescopic direction of the third pushing mechanism 703 is parallel to the turntable 2 and perpendicular to the telescopic direction of the telescopic end of the second pushing mechanism 701. The inner side of the hinge rod 702 is hinged to the telescopic end of a fourth pushing mechanism 704, and the fixed end of the fourth pushing mechanism 704 is hinged to one side of the support frame 7. When the telescopic end of the fourth pushing mechanism 704 is in a retracted state and the rectangular alignment frame 3 with the valve block 8 placed inside is rotated to face the support frame 7, the telescopic end of the second pushing mechanism 701 faces the corresponding first push rod 302, and the telescopic end of the third pushing mechanism 703 faces the corresponding second push rod 303. When it is necessary to push the first push rod 302 and the second push rod 303 to align the valve block 8 to be processed with the alignment hole 301, the telescopic end of the fourth pushing mechanism 704 is controlled to be pushed out, so that the first push rod 302 of the corresponding rectangular alignment frame 3 rotates to face the second pushing mechanism 701, and then the telescopic end of the fourth pushing mechanism 704 is controlled to retract, and then the telescopic ends of the second pushing mechanism 701 and the third pushing mechanism 703 are controlled to be pushed out.

[0032] For details, see Figure 2The first push rod 302 is sleeved with a first spring 3021, one end of the first spring 3021 is connected to the outward end of the rectangular alignment frame 3, and the other end of the first spring 3021 is connected to the first push rod 302. When the first push rod 302 moves inward, the first spring 3021 is in a compressed state. When the telescopic end of the second push mechanism 701 is retracted, the first push rod 302 is subjected to the elastic force of the first spring 3021 and moves outward to reset. For more details, refer to Figure 2 The second push rod 303 is inserted into a second slider 3031, and the second slider 3031 is slidably connected to the second slide groove 402. A second spring 3032 is sleeved on the second push rod 303, one end of the second spring 3032 is connected to the outer side of the slider, and the other end of the second spring 3032 is connected to the second push rod 303. When the second push rod 303 moves inward, the second spring 3032 is in a compressed state. When the telescopic end of the third pushing mechanism 703 retracts, the second push rod 303 will be subjected to the elastic force of the second spring 3032 and move outward to reset.
