Description

Technical Field

[0001] This utility model relates to the field of shot blasting machines, specifically a hook-type workpiece fixing bracket for shot blasting machines. Background Technology

[0002] A hook-type shot blasting machine, also known as a suspended shot blasting machine, is a machine that uses a hook and a workpiece holder to perform shot blasting by suspending the workpiece. Sometimes, the angle of the workpiece holder needs to be adjusted, which requires an adjustable angle workpiece holder. Chinese utility model patent application number 202421030411.0 discloses a workpiece holder for a hook-type shot blasting machine, including a main frame and a movable bracket hinged to the side of the main frame. Positioning plates are symmetrically welded to the left and right ends of the main frame, and movable grooves are formed on the positioning plates. Multiple adjustment holes are equidistantly formed on the positioning plates at the upper end of the movable grooves.

[0003] The aforementioned hook-type shot blasting machine's workpiece holder, designed to address the limitation of most workpiece holders having fixed structures and inability to adjust angles, allows for adjustment of the angle of the workpiece suspended at its lower end through the rotation of movable supports. This results in a more uniform coverage of the shot blasting stream on the workpiece surface, preventing missed or excessive blasting and improving the uniformity and integrity of the shot blasting cleaning. However, during use, a drawback was discovered: the movable supports on both sides of the main frame require individual angle adjustment, which is cumbersome and hinders work efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a hook-type workpiece fixing frame for shot blasting machines. This workpiece fixing frame allows for simultaneous angle adjustment of the movable supports on both sides of the main frame, effectively solving the problem that the movable supports in the prior art require separate angle adjustment, which is cumbersome and detrimental to improving work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hook-type workpiece fixing frame for shot blasting machines, comprising a vertical main frame, a lifting ring at the top of the main frame, horizontal plates fixedly fixed at intervals on the left and right sides of the main frame, a vertical plate fixed between the outer ends of the upper and lower horizontal plates, a first vertical through hole embedded in the horizontal plate, a second horizontal through hole spaced at intervals on the vertical plate, and an adjustable angle hanger installed on both the horizontal and vertical plates; The hanging bracket includes a movable bracket that extends horizontally through the second strip-shaped through hole. The movable bracket is hinged to the vertical plate at the second strip-shaped through hole via a first pivot. Several hanging holes are provided horizontally at intervals on the movable bracket outside the second strip-shaped through hole. The inner end of the movable bracket is hinged to the U-shaped frame with an open outer opening. The U-shaped frame is fixedly connected to the vertical rod on the inner side. The vertical rod extends vertically through the first strip-shaped through hole of the horizontal plate and is provided with an external thread at the upper first strip-shaped through hole. Locking nuts are provided on the vertical rods on the upper and lower sides of the upper first strip-shaped through hole.

[0006] As a preferred technical solution, the top of the vertical rod is threaded with a cylindrical limiting block.

[0007] As a preferred technical solution, the two sides of the first strip-shaped through hole in the width direction are in contact with the outer surface of the vertical rod.

[0008] As a preferred technical solution, the two sides of the second strip-shaped through hole in the width direction are respectively slidably engaged with the left and right sides of the movable bracket.

[0009] As a preferred technical solution, the main frame has a square cross-section.

[0010] As a preferred technical solution, the movable support is generally in the shape of a horizontal cuboid.

[0011] As a preferred technical solution, the hanging hole is located below the center of the movable bracket.

[0012] As a preferred technical solution, the horizontal plate and the vertical plate are integrally formed, and the whole is a U-shaped structure with side openings.

[0013] As a preferred technical solution, a rectangular cavity is embedded on the bottom surface of the main frame.

[0014] Compared with the prior art, this utility model provides a hook-type workpiece fixing bracket for shot blasting machines, which has the following advantages: 1. This utility model uses a movable bracket whose inner end is hinged to an open U-shaped frame. The U-shaped frame is fixedly connected to the inner vertical rod. The vertical rod passes through the first strip-shaped through hole of the horizontal plate and has an external thread at the upper first strip-shaped through hole. Locking nuts are provided on the vertical rods on both sides of the upper first strip-shaped through hole. In use, the workpiece can be suspended at the hanging hole of the movable bracket. When adjusting the angle, the locking nuts on both sides of the upper horizontal plate can be loosened to press down or lift the vertical rod. The U-shaped frame can drive the left end of the movable bracket to press down or pull up. The outer side of the movable bracket will rise or fall under the direction change of the first rotating shaft. After adjustment, the two locking nuts can be tightened. This allows the movable bracket on one side of the main frame to adjust the angle simultaneously, which helps to improve the overall work efficiency.

[0015] 2. This utility model has cylindrical limiting blocks threadedly connected to the top of the vertical rod. During use, the limiting blocks facilitate the grip of the staff and make it easy to lift or press down the vertical rod.

[0016] 3. This utility model has an integrally formed structure of horizontal and vertical plates, with the whole structure having a side opening U-shape. In use, the integrally formed structure of horizontal and vertical plates can increase the overall sturdiness and extend the service life. Attached Figure Description

Horizontal plates 2 are fixedly fixed vertically on the left and right sides of the main frame 1 at intervals. A vertical plate 3 is fixed between the outer ends of the upper and lower horizontal plates 2. The horizontal plates 2 are embedded with a first vertical strip-shaped through hole 21. The vertical plates 3 are provided with a second horizontal strip-shaped through hole 31 at intervals. An adjustable angle hanger 4 is installed on both the horizontal plates 2 and the vertical plates 3. The hanging bracket 4 includes a movable bracket 41 that extends horizontally through the second strip-shaped through hole 31. The movable bracket 41 is hinged to the vertical plate 3 at the second strip-shaped through hole 31 via a first rotating shaft 412. The movable bracket 41 on the outer side of the second strip-shaped through hole 31 is provided with several hanging holes 411 at horizontal intervals. The inner end of the movable bracket 41 is respectively hinged to the open U-shaped frame 42 (via the second rotating shaft 421). The U-shaped frame 42 is fixedly connected to the inner vertical rod 43. The vertical rod 43 extends vertically through the first strip-shaped through hole of the horizontal plate 2, and is provided with an external thread 44 at the upper first strip-shaped through hole 21. Locking nuts 45 are provided on the vertical rod 43 on the upper and lower sides of the upper first strip-shaped through hole 21.
