Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting hooks, in particular to an adjustable shot blasting machine hanger. Background Art

[0002] After the workpiece is cast, in order to remove impurities such as oxide scale on its surface to improve the appearance quality, it is usually necessary to perform shot blasting on it so that the surface of the workpiece reaches a certain roughness, which is conducive to subsequent surface treatment such as painting. Shot blasting is a cold treatment technology that uses a shot blaster to project shot material onto the surface of the workpiece at a very high speed and a certain angle. By controlling and selecting the particle size and shape of the shot material, as well as adjusting and setting the travel speed of the machine, different projectile intensities can be obtained and different surface treatment effects can be obtained. When using a shot blasting machine to clean castings, it is necessary to use a hanging bracket to lift the workpiece and send it to the shot blasting cleaning room for processing. According to the shape and structure of different castings, different hangers and slings are usually required. Small castings are hung too densely and there is a problem of uneven shot blasting. Large castings also have the safety hazard of falling off. In addition, loading and unloading workpieces requires a lot of labor costs. Therefore, different sizes of hangers need to be designed and prepared for different workpieces, which is easy to cause waste of resources.

[0003] The Chinese utility model patent with the document number CN218254653U discloses an adjustable shot blasting hook device, including a main rod and a hook assembly arranged on the surface of the main rod, the hook assembly includes at least two support rods, and the adjustable shot blasting hook device also includes an adjustment assembly, the adjustment assembly includes a slot opened on the surface of the main rod and a latch matched with the slot, the latch can be movably arranged in the support rod, and the latch moves from the distal end to the proximal end relative to the support rod and is inserted into the slot to fix the support rod. The device has a simple structure, and the position of the support rod is easy to adjust, which is suitable for the shot blasting requirements of different products. Although the invention can adjust the position of the support rod to meet the shot blasting requirements of different products, it only fixes the support rod by horizontally plugging and matching the slot opened on the surface of the main rod and the latch arranged on the support rod. When the suspended workpiece is too heavy, the support rod is deformed, and the latch is very easy to fall out, thereby damaging the workpiece or even causing a safety accident, and the firmness and stability of the hanger cannot be effectively guaranteed.

DETAILED DESCRIPTION

[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Embodiment 1:

[0026] like Figure 1As shown, the utility model proposes an adjustable shot blasting machine hanger device, including a main rod 1, the shape of the main rod 1 is preferably a rectangular parallelepiped or a cylinder, the top of the main rod 1 is fixedly connected with a hook 4 for hanging the hanger, the main rod 1 is provided with a plurality of through holes 2, the through holes 2 are evenly distributed on the side of the main rod 1, for the consideration of the tensile strength of the main rod 1, the through holes 2 are not easy to be arranged too densely, and it is best that the through holes 2 do not interfere with each other, the through holes 2 and the main rod 1 have a certain inclination angle, and the angle is preferably between 45°-75°, which is conducive to the support rod 3 to better hang the workpiece, and is also conducive to the loading and disassembly of the workpiece.

[0027] like Figure 2 As shown, the support rod 3 includes an insertion section 33 and a support section 32, and the insertion section 33 and the support section 32 are fixedly sleeved, and the rod diameter of the support section 32 is larger than the rod diameter of the insertion section 33. In order to facilitate the support rod 3 to bear force better, the support surface 35 at the connection between the insertion section 33 and the support end is also set as an inclined surface, and this inclination angle is consistent with the inclination angle of the through hole 2 and the rod body of the main rod 1, so that the support surface 35 can fit tightly with the rod body of the main rod 1, and the support rod 3 and the through hole 2 are slidably matched, and the insertion section 33 can be inserted into the through hole 2 and has a clearance fit with the through hole 2. When inserted, the support section 32 is always located obliquely above the through hole 2, thereby forming a stable support structure.

[0028] The detailed working process of this embodiment is: when in use, the hook 4 is hung on the conveying device, and according to the structure of the hung workpiece, the insertion section 33 of the support rod 3 is obliquely inserted into the through hole 2, so that the support surface 35 and the rod body of the main rod 1 are tightly fitted. After the support rod 3 is installed, the workpiece is hung on the support rod 3. The utility model arranges a plurality of through holes 2 which are inclined to penetrate the end surface on the main rod 1, and slides the support rod 3 in the through hole 2. The support rod 3 will slide downward in the through hole 2 under the action of gravity. However, because the insertion section 33 and the support section 32 are fixedly sleeved, the cross-section of the support section 32 is larger than the insertion section 33. The support section 32 is located obliquely above the through hole 2. The contact portion between the support section 32 and the through hole 2 will tightly press against the main rod 1 to prevent the support rod 3 from sliding out of the through hole 2, thereby forming a stable supporting structure. The utility model solves the technical problem of the instability of the adjustable hanger in the prior art. According to the differences in the cast workpieces, a plurality of support rods 3 can be inserted into the corresponding through holes 2 according to different structures, so that the overall structure meets the suspension requirements and can cope with a variety of cast workpieces. The installation and disassembly are very convenient, and the structure is also very firm and stable.

[0029] Embodiment 2:

[0030] like Figure 2As shown, in order to further enhance the firmness of the hanger, the insertion section 33 is further provided with an external thread 331, and the external thread 331 is located in the middle of the insertion section 33, and the through hole 2 is provided with an internal thread that is screwed together with the external thread 331. When in use, the external thread 331 on the support rod 3 is aligned with the internal thread in the through hole 2 and screwed. Based on the above further improvement, compared with the first embodiment, due to the tightening effect between the threads, the firmness of the support rod 3 and the main rod 1 is further enhanced.

[0031] Embodiment three:

[0032] like Figure 3 As shown, on the basis of Example 1, the adjustable shot blasting machine hanger device, in order to prevent the support rod 3 from falling off, the support rod 3 is also provided with a locking section 34 at the tail end of the insertion section 33, the locking section 34 and the insertion section 33 are of the same diameter, and the two are respectively fixedly connected to the locking mechanism, in order to enhance the locking effect, the locking surface 36 of the locking section 34 in contact with the insertion section 33 is also set as an inclined surface, and the supporting surface 35 is parallel, so that when the locking section 34 locks the support rod 3 through the locking mechanism, it can better contact with the rod body of the main rod 1, thereby providing a better locking effect.

[0033] like Figure 5 As shown, the locking mechanism includes a slide groove 361 and a sliding block 362. The cross-section of the sliding block 362 is convex-shaped, and the convex shape is inverted on the outer end surface of the locking section 34. The slide groove 361 is a convex-shaped groove that fits with the sliding block 362. The slide groove 361 is fixedly embedded in the free end surface of the insertion section 33. The length of the slide groove 361 is longer than that of the sliding block 362. The sliding block 362 can slide freely in the slide groove 361.

[0034] Embodiment 4:

[0035] like Figure 5 As shown, on the basis of the third embodiment, a slide rod 363 parallel to the slide groove 361 is fixedly arranged in the slide groove 361, and the sliding block 362 is provided with a sliding hole 364 for the slide rod 363 to slide therein. When the sliding block 362 slides in the slide groove 361, the locking section 34 and the insertion section 33 are tightly fitted on the locking surface 36.

[0036] When in use, after the support rod 3 is inserted into the through hole 2, the sliding block 362 will slide downward under the action of gravity, thereby driving the locking section 34 to move downward as a whole. Figure 4 As shown, the lower portion of the locking section 34 will come into contact with the rod body of the main rod 1, thereby forming a limit to prevent the support rod 3 from falling off. Based on the above further improvement, the fixing of the support rod 3 becomes more convenient.

[0037] Embodiment five:

[0038] like Figure 7 As shown, on the basis of Example 1, the adjustable shot blasting machine hanger device, the locking mechanism also includes a locking internal thread 365 and a locking external thread 366, the locking internal thread 365 is fixedly embedded in the free end face of the insertion section 33, the locking external thread 366 is protrudingly arranged on the outer end face of the locking section 34, and the locking internal thread 365 and the locking external thread 366 can be screwed together.

[0039] When in use, after the support rod 3 is inserted into the through hole 2, the locking section 34 is rotated along the thread direction. Figure 6 As described above, until the locking section 34 and the insertion section 33 are completely tightened, because the locking section 34 is not coaxial with the support rod 3 at this time, the protruding tail of the locking section 34 will have a limiting effect, making it impossible for the support rod 3 to move. Based on the above further improvements, the fastening effect of the support rod 3 is further enhanced.

[0040] Embodiment six:

[0041] On the basis of any of the foregoing embodiments, a plurality of protruding structures 31 are provided on the support segment 32, and the protruding structures 31 are evenly distributed on the outer surface of the support segment 32, and the shape is preferably cylindrical. Based on the above further improvements, the suspension effect of the support rod 3 is further enhanced, and the workpiece can be embedded in the angle between the protruding structure 31 and the support rod 3 according to the structure and size.

[0042] Embodiment seven:

[0043] On the basis of any of the foregoing embodiments, the bottom of the main rod 1 is also rotatably connected to a hook 4, and the hook 4 can rotate. Depending on the shape and structure of the workpiece, in order to achieve a better shot blasting effect, the main rod 1 can be turned upside down so that the rotating end of the hook 4 faces upward, so that the bracket has the function of rotation, and the same bracket can be hung on the bottom hook 4 to meet more diverse hanging needs.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
