Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a prefabricated building sleeve embedded part forming and processing device. Background Technology

[0002] Embedded parts are components pre-installed within concealed works. They are components placed during structural pouring for overlapping during the construction of the superstructure. This facilitates the installation and fixing of external engineering equipment foundations. Embedded parts are mostly made of metal, such as reinforcing steel or cast iron, but can also be made of non-metallic rigid materials such as wood and plastic. They are components with steel plates and anchor bars embedded in the structure, used for connecting structural or non-structural components for fixing purposes. For example, they are connectors used for later fixing (such as doors, windows, curtain walls, water pipes, gas pipes, etc.). These are commonly found at the connection points between concrete and steel structures.

[0003] However, in existing methods of processing embedded parts using reinforcing bars (threaded steel), the outer wall of the threaded steel often has ribs. Ordinary clamping devices for columnar objects typically clamp the ribs of the threaded steel, resulting in a smaller contact area between the clamping device and the threaded steel. This leads to slippage of the threaded steel during subsequent drilling, posing a safety hazard in production and reducing processing efficiency, thus limiting its practicality. Therefore, we propose a prefabricated building sleeve embedded part forming and processing device to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a prefabricated building sleeve embedded part forming and processing device to solve the problem that some existing prefabricated building sleeve embedded part forming and processing devices have poor fixing effect on threaded steel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated building sleeve embedded part forming and processing device, including a base, a placement cylinder provided on the upper side of the base, a through groove opened inside the placement cylinder, a groove opened on the inner wall of the through groove, a clamping plate slidably connected inside the groove, a rib groove opened on the surface of the clamping plate, a sliding groove opened on the inner wall of the groove, the sliding groove extending out of the outside of the placement cylinder, a connecting block slidably connected inside the sliding groove, the connecting block and the clamping plate being fixedly connected, a first return spring being fixedly connected between the clamping plate and the inner wall of the groove, an operating cylinder threadedly connected to the outside of the placement cylinder, an extrusion groove opened on the inner wall of the operating cylinder, a cavity opened inside the base, a rotating component being provided inside the cavity, and a drilling unit slidably connected to the upper surface of the base.

The operation steps are few and the positioning efficiency is high. At the same time, the threaded steel can be fixed again by means of the rib groove, which effectively improves the stability of the threaded steel during processing, ensures the processing efficiency, improves the processing safety, and prevents the problem of slippage that may occur due to the small friction surface during drilling.

[0015] 2.

[0025] Please see Figures 1-7 This utility model provides a technical solution: a prefabricated building sleeve embedded part forming and processing device, including a base 1, a placement cylinder 2 is provided on the upper side of the base 1, a through groove 3 is provided inside the placement cylinder 2, the inside of the through groove 3 is used to place the threaded steel to be processed, a groove 4 is provided on the inner wall of the through groove 3, a clamping plate 5 is slidably connected inside the groove 4, a rib groove 6 is provided on the surface of the clamping plate 5, a sliding groove 7 is provided on the inner wall of the groove 4, the sliding groove 7 extends out of the outside of the placement cylinder 2, a connecting block 8 is slidably connected inside the sliding groove 7, the connecting block 8 and the clamping plate 5 are fixedly connected, a first return spring 9 is fixedly connected between the clamping plate 5 and the inner wall of the groove 4, an operating cylinder 10 is threadedly connected to the outside of the placement cylinder 2, an extrusion groove 11 is provided on the inner wall of the operating cylinder 10, the extrusion groove 11 is frustum shaped, a cavity 21 is provided inside the base 1, a rotating component is provided inside the cavity 21, and a drilling unit 12 is slidably connected to the upper surface of the base 1.

[0026] The punching unit 12 is a prior art in this field. For details, please refer to the device for punching threaded steel in publication number CN110802253A. The punching unit 12 in this solution has the same principle and structure as the prior art, so it will not be described in detail below. The inner diameter of the clamping plate 5 is matched with the outer diameter of the threaded steel to be processed, thereby ensuring the stability of the clamping.

[0027] In the above embodiments, this solution does not limit the number of grooves 4, clamping plates 5, sliding grooves 7 and connecting blocks 8. In actual operation, as long as the threaded steel inside the through groove 3 can be clamped and positioned, it is sufficient. The three are shown in the figure only for ease of description. In actual processing and production, there can be four, five, etc.

[0028] The surface of the connecting block 8 is provided with a relief groove 14, and a pulley 15 is rotatably connected inside the relief groove 14. The connecting block 8 contacts the inner wall of the extrusion groove 11 by means of the pulley 15. The setting of the pulley 15 can improve the smoothness of the operation cylinder 10 when it moves, and effectively avoid the situation of jamming between the structures.

[0029] The rotating assembly includes a rotating shaft 22, which is rotatably connected inside the cavity 21. The upper end of the rotating shaft 22 rotatably extends through the upper surface of the base 1, and a mounting plate 16 is fixedly connected to the upper end of the rotating shaft 22.

[0030] The mounting plate 16 has an internal mounting groove 17, and an mounting rod 18 is provided inside the mounting groove 17. The mounting rod 18 is fixedly connected to the placement cylinder 2.

[0031] The mounting plate 16 has an internal threaded connection with a mounting bolt 19, and the surface of the mounting rod 18 has a circular groove 20. The circular groove 20 and the mounting bolt 19 are compatible. Through the cooperation between the mounting groove 17, the mounting rod 18, the mounting bolt 19 and the circular groove 20, it is convenient for the staff to replace the placement cylinder 2 and its external mechanism.

[0032] A drive rod 23 is rotatably connected inside the cavity 21. The drive rod 23 rotatably extends through the outside of the base 1. Both the drive rod 23 and the rotating shaft 22 are fixedly fitted with bevel gears 24 at one end inside the cavity 21. The two bevel gears 24 are meshed together. When the operator rotates the drive rod 23, the rotating shaft 22 can be driven to rotate under the transmission of the bevel gears 24, thereby realizing the rotation of the mounting plate 16 and the placement cylinder 2, so as to facilitate the subsequent processing of the other end of the threaded steel.

[0033] A handle 25 is provided at one end of the drive rod 23 located outside the base 1. A movable chamber 26 is opened inside the handle 25. The drive rod 23 slides through the interior of the movable chamber 26. A rectangular plate 27 is fixedly connected to one end of the drive rod 23 located inside the movable chamber 26. The rectangular plate 27 and the movable chamber 26 are slidably connected. A second return spring 28 is fixedly connected between the rectangular plate 27 and the inner wall of the movable chamber 26.

[0034] Four locking rods 29 are fixedly connected to the side surface of the handle 25 facing the base 1. Four locking slots 13 are provided on the side surface of the base 1 facing the handle 25. The four locking slots 13 are respectively adapted to the four locking rods 29. By inserting the locking rods 29 into the inside of the locking slots 13, and with the help of the second return spring 28, the locking rods 29 are guaranteed not to disengage from the inside of the locking slots 13, thereby ensuring the stability of the drive rod 23 and preventing the mounting plate 16 from rotating.

[0035] Working principle:

[0036] When using this prefabricated building sleeve embedded part forming and processing device, the operator inserts the threaded steel to be processed into the through groove 3, and then rotates the operating cylinder 10. Because the operating cylinder 10 is threadedly connected to the placement cylinder 2, the operating cylinder 10 will move outside the placement cylinder 2. At this time, under the restriction of the extrusion groove 11, the three connecting blocks 8 will be forced to move. The three connecting blocks 8 will slide inside the sliding groove 7, and at the same time, the three clamping plates 5 will clamp the threaded steel. The rib groove 6 will be inserted into the outer side of the rib on the surface of the threaded steel. Finally, by rotating the operating cylinder 10, multiple clamping plates 5 can simultaneously clamp and position the threaded steel.

[0037] The operator can then operate the drilling unit 12 to drill a hole at one end of the threaded steel. When drilling is required at the other end, the operator pulls the handle 25 outward. At this time, the handle 25 will slide outside the drive rod 23, and the second return spring 28 will undergo elastic deformation until the locking rod 29 disengages from the locking groove 13. The operator then rotates the handle 25 until the other end of the threaded steel is aligned with the drilling unit 12. At this time, the handle 25 will rotate 90 degrees, and the locking rod 29 will be aligned with the locking groove 13 again. Afterward, releasing the handle 25 will allow the locking rod 29 to re-enter the locking groove 13 using the elastic force of the second return spring 28, thereby locking the drive rod 23.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
