DETAILED DESCRIPTION

[0021] 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.

[0022] like Figure 1 As shown, the utility model is a special operating fixture used for the production and transportation bottom plate of aerated bricks, including a fixture middle plate 1, a fixture moving plate 2 is provided on the front and rear sides of the fixture middle plate 1, a cross-section concave strip 3 is fixedly provided on both sides of the outer surface of the fixture moving plate 2, and half of the cross-section concave strip 3 is movably inserted into the interior of the fixture middle plate 1, a fixture head 4 is fixedly installed on one side of the upper end surface of the two fixture moving plates 2, and an automatically locking adjustment mechanism is installed inside the fixture middle plate 1, and the two fixture moving plates 2 can be synchronously moved outward or inward through the automatically locking adjustment mechanism.

[0023] As the preferred technical solution of this embodiment, Figure 3 As shown, the automatically locking adjustment mechanism includes a stepper motor 5, the output shaft of the stepper motor 5 is connected to a motor shaft 6 through a coupling, and a bevel gear A7 is fixedly sleeved on the lower side of the outer surface of the motor shaft 6; when it is necessary to adjust the distance between the two clamp heads 4 according to the size of the transport base plate, the stepper motor 5 is started, and the stepper motor 5 can drive the motor shaft 6 connected thereto and the bevel gear A7 fixedly sleeved on the outer surface of the motor shaft 6 to rotate.

[0024] A bevel gear B8 is meshed on both sides of the outer surface of the bevel gear A7, and a transmission shaft 9 is connected to the axis of the bevel gear B8. A threaded rod 10 is fixedly connected to one end of the transmission shaft 9. A storage groove 11 located inside the fixture moving plate 2 is provided on the outer side of the threaded rod 10, and an internal threaded through hole 12 located on the outer surface of the fixture moving plate 2 is provided on one side of the inner wall of the storage groove 11, and the external thread of the threaded rod 10 matches the internal thread of the internal threaded through hole 12; when the bevel gear A7 rotates, the bevel gear B8 meshed with it and the transmission shaft 9 connected to the axis of the bevel gear B8 will also rotate accordingly, and when the transmission shaft 9 rotates, the threaded rod 10 fixed thereto will also rotate. Rotation, when the threaded rod 10 rotates, the internal thread of the internal threaded through hole 12 is transmitted, and the concave strip 3 fixed on its outer surface section is inserted into the inside of the clamp middle plate 1, so that the clamp moving plate 2 which cannot rotate by itself will move back and forth under the transmission of this threaded structure. At this time, the distance between the two clamp heads 4 is adjusted according to the size of the transport base plate. When the position adjustment of the clamp head 4 is completed, the stepper motor 5 can be turned off. Through the above technical solution, the device can move the clamp head 4 to the corresponding position according to a variety of transport base plates of different sizes, so that the device itself can grab a variety of transport base plates of different sizes, thereby improving the adaptability of the equipment.

[0025] One end of the threaded rod 10 is fixedly connected to an anti-slip plate 13, the outer surface diameter of the anti-slip plate 13 is the same as the inner wall diameter of the storage groove 11, and the inner wall diameter of the storage groove 11 is larger than the inner wall diameter of the internal threaded through hole 12; the anti-slip plate 13 can prevent the threaded rod 10 from completely passing through the internal threaded through hole 12.

[0026] As the preferred technical solution of this embodiment, Figure 4 As shown, a cylindrical groove 14 located inside the middle plate 1 of the fixture is provided on the outer side of the middle position of the motor shaft 6, and a gear 17 is provided on the lower side of the cylindrical groove 14. The lower end surface of the gear 17 is connected to the inner wall of the cylindrical groove 14 through a roller bearing.

[0027] The gear 17 is meshed with a gear column 20, and the upper end surface of the gear column 20 is connected to a locking motor 21 fixedly mounted on the inner wall of the clamp middle plate 1; when the position adjustment of the two clamp heads 4 is completed, the locking motor 21 is started, and the locking motor 21 can drive the gear column 20 connected thereto and the gear 17 meshed with the gear column 20 to rotate.

[0028] A beveled internal threaded sleeve 19 is provided above the gear 17, and a synchronization rod 18 is fixedly provided on both sides of the upper end surface of the gear 17, and the synchronization rod 18 vertically moves through the beveled internal threaded sleeve 19; since the two synchronization rods 18 fixed to the upper end surface of the gear 17 both vertically move through the beveled internal threaded sleeve 19, when the gear 17 rotates, the beveled internal threaded sleeve 19 will rotate synchronously therewith.

[0029] An external thread sleeve 15 matching its internal thread is provided on the upper side of the interior of the inclined internal thread sleeve 19, and the external thread sleeve 15 is located on the outer side of the motor shaft 6, and the upper end face of the external thread sleeve 15 is fixed to the inner wall of the cylindrical groove 14, and a strip groove 16 is provided at each of the four end corners of the outer surface of the external thread sleeve 15, and a circle of anti-slip stripes is provided on the inner wall of the external thread sleeve 15, and the inner wall diameter of the inclined internal thread sleeve 19 gradually decreases from top to bottom; through the transmission of the thread structure, the rotating inclined internal thread sleeve 19 can move up and down, and at this time, the inclined internal thread sleeve 19 is moved upward, because the outer surface of the external thread sleeve 15 is provided with four anti-slip stripes, the inner wall diameter of the inclined internal thread sleeve 19 gradually decreases from top to bottom. The outer thread sleeve 15 is a strip groove 16, and the inner wall diameter of the inclined internal thread sleeve 19 gradually decreases from top to bottom. As the inclined internal thread sleeve 19 gradually rises, the outer thread sleeve 15 itself will be gradually compressed, and its inner wall will gradually become smaller, until the inner wall of the outer thread sleeve 15 contacts the outer surface of the motor shaft 6. When the inner wall of the outer thread sleeve 15 contacts the motor shaft 6, it can be fixed. By fixing the motor shaft 6, the positions of the two clamp heads 4 can be prevented from changing. The above technical solution ensures the stability of the device and prevents the two clamp heads 4 from moving due to the influence of the external environment.

[0030] When it is necessary to release the fixation of the motor shaft 6 and adjust the positions of the two clamp heads 4 again, the locking motor 21 is started again and the inclined internal thread sleeve 19 is moved downward.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
