Abstract
Description
Technical Field
[0001] The utility model relates to an automatic sand-cleaning turning mechanism for a workpiece of a shot blasting production line, belonging to the technical field of workpiece surface treatment. Background Art
[0002] For a type of large workpiece with high requirements for surface smoothness, such as a bridge anti-vibration bearing with a concave spherical surface, after the casting of the blank is completed, the concave spherical surface needs to be sandblasted (shot blasted). Due to the very large impact force of sandblasting during grinding, some sand pills and grinding dust are attached to the concave spherical surface after grinding. After grinding, the concave spherical surface needs to be cleaned with a strong blow gun. Due to the large volume of the concave spherical surface of the anti-vibration bearing, it is difficult for the blow gun to completely blow out the dust particles, and the workpiece needs to be turned over during the blowing process. However, the bridge anti-vibration bearing weighs hundreds of kilograms, and it is almost impossible to complete it completely by manual flipping. The existing practice is to place the workpiece on a flipping device with a rotating shaft, and manually clamp the workpiece and rotate the device to achieve the flipping of the workpiece. This not only wastes labor, but also makes the operator very tired. Utility Model Content

DETAILED DESCRIPTION
[0022] like Figure 1As shown in FIG. 3, an automatic flipping mechanism for sand cleaning of workpieces in a shot blasting production line includes a rolling cage 1 controlled by a production line control system and driven by electricity. The rolling cage 1 includes a cage frame 11 and an upper limit device 12, a left clamp 13, and a right clamp 14 controlled and operated by the production line control system. The middle part of the cage frame 11 has a stand 111 for placing the workpiece 4. The left clamp 13 and the right clamp 14 can push toward each other to clamp the workpiece 4. The upper limit device 12 is used to prevent the workpiece from tilting away from its original position when the cage frame 11 rotates. During operation, the blow gun starts to blow the workpiece with a concave surface on the stand 111. The control system controls the left clamp 13 and the right clamp 14 to push toward each other to clamp the workpiece, and at the same time limits the upper limit device 12 in place. The rolling cage 1 slowly rotates 180 degrees under the control of the production line control system to dump the dust particles blown off by the blow gun, and then rotates back to the stand to restore the horizontal level. In this way, the entire sand cleaning process does not require manual labor, which significantly reduces production costs.
[0023] The upper limit device 12 comprises a limit frame 121 disposed above the platform 111 . The limit frame 121 can move up and down and stay at any position in the movement range to accommodate workpieces of different heights.
[0024] The left clamp 13, the right clamp 14 and the limit frame 121 are pushed by propulsion cylinders, namely the left clamp propulsion cylinder 151, the right clamp propulsion cylinder 152 and the limit frame propulsion cylinder 153. The propulsion cylinders can be air cylinders, oil cylinders and electric cylinders.
[0025] like Figure 3 , 4 As shown, the upper limit device 12 further includes an elastic buffer pad 122, which is installed between the placed workpiece 4 and the limit frame 121, and a dust clearance 16 is provided between the buffer pad 122 and the workpiece 4. In this way, it is possible to prevent the upper limit frame 121 from directly touching the workpiece and causing damage to the workpiece, and at the same time, during the workpiece tipping process, dust particles are tipped out before the workpiece tips and does not contact the buffer pad 122.
[0026] The buffer pad 122 has a plurality of dust holes 123 communicating with each other from top to bottom. When in use, a certain gap is also reserved between the downward limiting frame 121 and the buffer pad 122, so that dust particles can fall through the dust holes and the gap when the workpiece 4 is tipped. The provision of the dust holes 123 can also reduce the effect of the buffer pad.
[0027] like Figure 1 , 2 As shown, at least one end of the rolling cage 1 is connected to the conveyor belt of the shot blasting production line, and the platform 111 is at the same height as the conveyor belt. Like this, the workpiece transmitted by the conveyor belt can directly enter the platform 111 and can be transferred away through the conveyor belt.
[0028] Furthermore, the stand 111 is composed of a plurality of rotatable rollers 1111 , one end of the rollers 1111 has a gear 1112 , and the gears 1112 of all the rollers 1111 are driven by the same chain 1113 , so that the workpiece 4 can automatically enter and exit the rolling cage 1 .
[0029] The automatic flipping mechanism also includes a seat frame 2, and two small rollers 21 that can rotate freely are respectively arranged at the left and right ends of the seat frame 2, and a large roller 17 fixed to the cage frame 11 is respectively provided at the two ends of the rolling cage 1. The rolling cage 1 is placed on the small rollers 21 at the two ends of the seat frame 2 through the large rollers 17 at the two ends. The automatic flipping mechanism also includes a driving motor 3 that drives the rolling cage 1 to rotate forward and reversely, and a large gear 18 fixed to the large roller 17 is provided on one side of the large roller 17, and the large gear 18 is driven to rotate by the driving motor 3.
[0030] The above embodiments are only used to more clearly describe the present invention and cannot be regarded as limiting the protection scope of the present invention. Any modifications in equivalent forms should be regarded as falling within the protection scope of the present invention.
