Technical Field

[0001] The utility model relates to the technical field of sandblasting clamping, in particular to a quick clamping mechanism suitable for sandblasting the outer wall of a small shell. Background Art

[0002] Sandblasting is a process for surface treatment of workpieces. Compressed air is used as the power to form a high-speed jet beam to spray the material (copper ore sand, quartz sand, corundum, iron sand, sea sand) at high speed onto the surface of the workpiece to be treated, so that the appearance or shape of the workpiece surface changes. Due to the impact and cutting action of the abrasive on the workpiece surface, the surface of the workpiece obtains a certain degree of cleanliness and different degrees of roughness, and the mechanical properties of the workpiece surface are improved, thereby improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, extending the durability of the coating, and also facilitating the leveling and decoration of the coating.

[0003] However, when the outer walls of some small shells need to be sandblasted, it is inconvenient to clamp them using the existing clamping mechanism due to their small size, and it is difficult to fix them, thus affecting the sandblasting processing time. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a quick clamping mechanism suitable for sandblasting the outer wall of a small shell, comprising a fixed plate, a bearing seat is fixedly installed inside the fixed plate, a rotating component is fixedly installed inside the bearing seat, a connecting component is installed on the top of the rotating component, and a clamping component for clamping the small shell is installed on the top of the connecting component.

[0006] Further: the rotating assembly includes a needle roller bearing and a rotating shaft, the needle roller bearing is fixedly installed inside the bearing seat, and the rotating shaft is fixedly installed inside the needle roller bearing.

[0007] Further: A driving wheel for driving the rotating component is fixedly installed inside the rotating shaft.

[0008] Further: the connecting assembly includes a connecting block, a first screw hole, a second screw hole and a fixing bolt. The connecting block is slidably installed on the top of the rotating shaft. The first screw holes have two symmetrically distributed inside the connecting block, the second screw holes have two symmetrically distributed inside the rotating shaft and correspond to the first screw hole, and the fixing bolts have two installed in the first screw hole and the second screw hole in sequence.

[0009] Further: the clamping assembly includes a mounting shaft, a mounting groove, a tensioning plate and a tensioning spring, the mounting shaft is fixedly connected to the inside of the connecting block, a plurality of tensioning plates distributed in a ring are fixedly connected to the top of the connecting block, the mounting groove has a plurality of openings on the outer wall of the mounting shaft and the inside of the tensioning plate, the tensioning spring is fixedly installed between the mounting groove and the tensioning plate and is located inside the mounting groove.

[0010] Further: a plurality of fixing holes distributed in an annular shape are provided inside the fixing plate.

[0011] The utility model has the following beneficial effects:

[0012] 1. Compared with the prior art, by setting a tensioning sheet and a tensioning spring, the shell opening is downwardly covered on the tensioning sheet. Due to the tensile force of the tensioning spring, the tensioning sheet contacts the inner wall of the shell and generates a certain pressure. The shell can be stably fixed on the clamping assembly to prevent the shell from rotating freely during sandblasting. When the sandblasting is completed and the shell is removed, the shell can be directly pulled out, which can solve the problem that the small shell is difficult to fix due to its small size.

[0013] 2. Compared with the prior art, by setting a rotating shaft, a connecting block, a first screw hole, a second screw hole and a fixing bolt, during installation, the connecting block is installed on the top of the rotating shaft, the first screw hole needs to be aligned with the second screw hole, and then the fixing bolt is installed inside the first screw hole and the second screw hole, so that the connecting block can be fixed on the top of the rotating shaft. During disassembly, the fixing bolt is taken out, and then the connecting block can be removed, which can solve the problem of equipment wear caused by the sandblasting environment, thereby affecting the clamping effect.

First, the equipment is fixed on the sandblasting production line through the fixed plate 1, and then the connecting component is installed on the top of the rotating component. Then, when in use, the small shell is installed on the clamping component, and then the rotation of the rotating component drives the connecting component and the clamping component to rotate simultaneously, and drives the small shell to rotate for sandblasting.

[0022] The rotating assembly includes a needle bearing 4 and a rotating shaft 5. The needle bearing 4 is fixedly installed inside the bearing seat 3, and the rotating shaft 5 is fixedly installed inside the needle bearing 4. When in use, the rotating shaft 5 is installed inside the bearing seat 3 through the needle bearing 4, so that the rotating shaft 5 can rotate automatically inside the bearing seat 3.

[0023] A driving wheel 6 for driving the rotating assembly is fixedly installed inside the rotating shaft 5. When in use, the driving wheel 6 is connected to the driving motor through a transmission component. Then, when the driving motor is started, the rotating assembly is driven to rotate through the driving wheel 6.

[0024] The connecting assembly includes a connecting block 7, a first screw hole 8, a second screw hole 9 and a fixing bolt 10. The connecting block 7 is slidably installed on the top of the rotating shaft 5. The first screw hole 8 has two symmetrically distributed inside the connecting block 7, the second screw hole 9 has two symmetrically distributed inside the rotating shaft 5 and corresponding to the first screw hole 8, and the fixing bolt 10 has two installed in the first screw hole 8 and the second screw hole 9 in sequence. When in use, the connecting block 7 is installed on the top of the rotating shaft 5, and the first screw hole 8 and the second screw hole 9 need to be aligned. Then, the fixing bolt 10 is installed in the first screw hole 8 and the second screw hole 9, so that the connecting block 7 can be fixed on the top of the rotating shaft 5. After the sandblasting environment causes wear to the equipment, the clamping assembly can be easily replaced through the connecting assembly.

[0025] The clamping assembly includes a mounting shaft 11, a mounting groove 12, a tensioning piece 13 and a tensioning spring 14.

The mounting groove 12 has a plurality of openings on the outer wall of the mounting shaft 11 and the inside of the tensioning piece 13. The tensioning spring 14 is fixedly installed between the mounting groove 12 and the tensioning piece 13 and is located inside the mounting groove 12. When in use, the shell opening is downwardly sleeved on the tensioning piece 13. Due to the tensile force of the tensioning spring 14, the tensioning piece 13 contacts the inner wall of the shell and generates a certain pressure. The shell can be stably fixed on the clamping assembly to prevent the shell from rotating freely during sandblasting. When the sandblasting is completed and the shell is removed, the shell can be directly pulled out.

[0026] A plurality of fixing holes 2 distributed in a ring shape are provided inside the fixing plate 1 . When in use, the device can be fixed on the sandblasting production line through the fixing holes 2 .

[0027] Working principle: First, install and fix the equipment on the sandblasting production line through the fixing hole 2 in the fixing plate 1. Then, when using, put the shell opening downward on the tensioning plate 13. Due to the tensile force of the tensioning spring 14, the tensioning plate 13 contacts the inner wall of the shell and generates a certain pressure. The shell can be stably fixed on the clamping assembly to avoid free rotation of the shell during sandblasting. When the sandblasting is completed and the shell is removed, just pull out the shell. During long-term use, the sandblasting environment will cause serious wear to the clamping assembly, affecting the clamping effect. At this time, remove the fixing bolt 10, and then replace the connecting block 7 and the clamping assembly.
