DETAILED DESCRIPTION

[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0024] like Figure 1-3 As shown, a horizontal rotary plate for a boring machine includes a mounting plate 1, on which two pairs of chute mounting plates 2 are arranged, and on the two chute mounting plates 2, two symmetrically distributed tightening mechanisms 4 are arranged;

[0025] The tightening mechanism 4 includes a push plate 41, a push threaded rod 44 and a sliding mechanism. The upper free end of the push plate 41 is provided with an open semicircular hole for engagement. The push threaded rod 44 is engaged with the lower thread of the push plate 41. One end of the push threaded rod 44 abuts against the side of one of the chute mounting plates 2.

[0026] Upper latching slots 21 are provided on the upper surfaces of the two chute mounting plates 2 , and lower latching slots 23 are provided on the opposite sides of the two chute mounting plates 2 .

[0027] As an optional embodiment, the sliding mechanism includes a lower clamping plate 45 and an upper clamping plate 47 fixedly connected to it. The upper clamping plate 47 is sleeved in the upper clamping slot 21, and the lower clamping plate 45 is sleeved in the lower clamping slot 23. The inner top surface of the lower clamping slot 23 is provided with a groove, and an embedded clamping plate 46 is sleeved in the groove. The lower clamping plate 45 is fixedly connected to the embedded clamping plate 46. Such an arrangement allows the tightening mechanism 4 to slide on the slot mounting plate 2 by relying on the sliding mechanism, which can facilitate sliding adjustment of the position of the main shaft or fixed shaft, thereby improving its actual application effect.

[0028] Furthermore, the upper clamping plate 47 is rotatably provided with a movable seat 43, the movable seat 43 is provided on the ejecting plate 41, the ejecting plate 41 is provided with a reinforcing plate 42, and the lower clamping plate 45 is sleeved with the ejecting threaded rod 44 through the formed inner clamping hole. Such a setting allows the ejecting threaded rod 44 to form a support against the side of the slide mounting plate 2 when it is rotated and adjusted, and at the same time restricts the sliding of the tightening mechanism 4 to improve the tightening effect.

[0029] Refer to the attached Figure 2 The upper surfaces of the two slide mounting plates 2 are provided with a plurality of evenly distributed spiral holes. The two slide mounting plates 2 are provided with fastening plates 3. The fastening plates 3 are installed on the two slide mounting plates 2 by fastening the hexagon socket screws. The fastening plates 3 are provided with a fixed shaft for installing the scraper. Such a setting can facilitate the fastening plates 3 to be fastened and fixed after sliding to the specified position on the slide mounting plates 2 by the hexagon socket screws, thereby improving the fixing effect of the fastening plates 3.

[0030] Furthermore, internal trip slots 22 are provided on the opposite sides of the two slide mounting plates 2, and an embedded sliding plate 31 is provided between the two slide mounting plates 2. The two internal trip slots 22 are each provided with a sliding trip block 32, and the two sides of the embedded sliding plate 31 are respectively fixedly connected to the two sliding trip blocks 32. Such an arrangement can facilitate the sliding connection between the sliding trip block 32 and the internal trip slot 22 to limit the sliding trajectory of the fastening plate 3, thereby improving the adjustment convenience.

[0031] Furthermore, a movable hole for adjusting the main shaft is provided on the mounting plate 1, and such a setting facilitates feed adjustment of the main shaft.

[0032] With the above structure, by sliding the top mechanism, the upper clamping plate 47 on the tightening mechanism 4 slides along the upper clamping slot 21, and the lower clamping plate 45 slides along the lower clamping slot 23, so that the tightening can slide to correspond to the main shaft or fixed shaft, and then the adjusting threaded rod is rotated by a wrench or other tool to make the adjusting threaded rod rest on the side of the slot mounting plate 2 to form a support, driving the pushing plate 41 to rotate and support on the movable seat 43, so that the open semicircular hole at the free end of the upper side of the pushing plate 41 is engaged with the main shaft or fixed shaft, and then the pushing threaded rod 44 is continuously rotated to increase the tightening force of the pushing plate 41 on the main shaft or fixed shaft, thereby improving the stability of the main shaft or fixed shaft during rotation.

[0033] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
