DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6 , a vibrating sand-falling machine for quickly fixing castings, comprising a horizontal plate 1, a bottom wall of the horizontal plate 1 is provided with a plurality of supporting legs 2, this scheme refers to the disclosure (announcement) number: CN218362040U, specifically "a vibrating sand-falling machine for quickly fixing castings", and is improved. The horizontal plate 1 and the supporting legs 2 in this scheme are equal to the crossbeam in the above scheme, and the remaining equipment components are not improved in this scheme, so they are not drawn in this scheme and are not described in detail. For details, please refer to the above scheme disclosure.

[0024] A turntable 4 is provided on the horizontal plate 1 through a rotating opening 3, a rotating motor is provided on the upper end surface of the horizontal plate 1 through an equipment slot, the rotating motor is connected to the turntable 4 through a rotating mechanism, a movable opening 5 is provided on the turntable 4, a screw 7 is provided in the movable opening 5 through the movable motor, a nut 8 is threadedly sleeved on the screw 7, a fixing frame 6 is provided on the nut 8 through an insertion mechanism, a vibrating sand-falling air hammer is installed on the fixing frame 6, an extrusion groove 19 is provided on the fixing frame 6, a hanging block 11 is provided in the extrusion groove 19 through a first extrusion mechanism, a hanging groove 10 is provided on the upper end surface of the horizontal plate 1, a toggle groove 14 is provided on the upper end surface of the horizontal plate 1, a slide rod 16 is provided in the toggle groove 14, a limit plate 15 is provided on the slide rod 16 through a second extrusion mechanism, and an annular groove 13 is provided in the rotating opening 3.

[0025] The rotating mechanism includes a gear 17 arranged on the output shaft of the rotating motor, and a ring gear 12 is provided on the turntable 4. The gear 17 is meshed with the ring gear 12. With the help of the gear 17 and the ring gear 12, the power transmission of the rotating motor is realized, so that the rotating motor can drive the turntable 4 to rotate in the rotating port 3.

[0026] The plug-in mechanism includes an insert block 9 arranged on the nut 8, a U-shaped connecting groove is provided on the fixing frame 6, and a slot corresponding to the insert block 9 is provided on the U-shaped connecting groove. After the insert block 9 is inserted into the slot, and when the fixing frame 6 cannot fall vertically and disengage from the nut 8, the nut 8 moves on the screw rod 7 to realize the synchronous movement operation of the fixing frame 6.

[0027] The first extrusion mechanism includes a first spring arranged in the extrusion groove 19, and the two ends of the first spring are elastically connected to the outer wall of the hanging block 11 and the inner wall of the extrusion groove 19 respectively. The first spring realizes the extrusion operation of the hanging block 11, and squeezes it into the hanging groove 10 to achieve vertical limitation of the fixing frame 6, so that it can neither rise nor fall.

[0028] The second extrusion mechanism includes a second spring arranged in the toggle groove 14, and the two ends of the second spring are elastically connected to the outer wall of the limit plate 15 and the inner wall of the toggle groove 14 respectively. The second spring realizes the extrusion of the limit plate 15 to ensure that its horizontal part is in the annular groove 13, ensuring that the turntable 4 cannot move vertically in the rotating mouth 3, but can rotate in the rotating mouth 3, wherein the surface of the limit plate 15 corresponding to the arc-shaped inner wall of the annular groove 13 is arc-shaped and smooth.

[0029] The upper end surface of the hanging block 11 is inclined, and the inclined surface of the hanging block 11 is polished. The inclination and polishing ensure that when the fixing frame 6 is raised and inserted into the movable opening 5, it can be squeezed into the extrusion groove 19 by relying on the bottom wall of the turntable 4.

[0030] The utility model has a reference publication (announcement) number of CN218362040U, specifically "a vibrating sand-falling machine for quickly fixing castings". By improving some components, the original advantages of quickly fixing castings, automatically striking different positions on the surface of castings and collecting falling sand are further improved, and the machine has a wider striking range.

[0031] When the utility model is used, the rotating motor is started to drive the rotating disk 4 to rotate relative to the horizontal plate 1 by means of the gear 17 and the gear ring 12, thereby driving the fixing frame 6 and the vibrating sand-falling air hammer to move in a circular shape for striking.

[0032] When the utility model is used, starting the movable motor can drive the screw rod 7 to rotate. When the screw rod 7 rotates, the nut 8 on the screw rod can cooperate with the fixing frame 6 to drive the vibrating sand-falling air hammer to move horizontally for striking.

[0033] The above two moving methods are used together to ensure the striking range.

[0034] In this solution, by pressing the hanging block 11 in the hanging groove 10, the hanging block 11 enters the extrusion groove 19 and disengages from the hanging groove 10, the vertical limit of the fixing frame 6 can be released, and the vibrating sand-falling air hammer can be driven to fall and disengage from components such as the screw 7.

[0035] In this solution, after the limit plate 15 in the toggle groove 14 is moved so that its horizontal part is disengaged from the annular groove 13, the vertical limit of the turntable 4 in the rotating mouth 3 can be released, and the turntable 4 and other components can be disengaged from the cross plate 1 and the gear 17 and other components.

[0036] In this solution, multiple components can be flexibly installed and easily disassembled, which provides high convenience for their inspection, maintenance or replacement.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
