Abstract
Description
Technical Field
[0001] The utility model relates to the field of production equipment, in particular to a blocking device for a cold grinding conveying platform. Background Art
[0002] During the production and processing of diesel engines, they need to be transported to the production line for cold grinding. When a certain number of diesel engines are transported to the production line, in order to avoid the subsequent continuous transportation of diesel engines to the production line, affecting the normal cold grinding process on the production line, a blocking device is set at the front end of the production line to facilitate the orderly transportation of diesel engines to the production line one by one.
[0003] The limit lever of the traditional blocking device is lifted or retracted at a relatively slow speed, resulting in the limit lever being unable to effectively block the diesel engine in a timely manner. In addition, the limit lever of the traditional blocking device cannot flexibly adjust the lifting height of the limit lever according to practical needs, and has poor flexibility in use, so it still needs to be improved.

DETAILED DESCRIPTION
[0014] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.
[0015] Any feature of this specification, unless otherwise specified, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise specified, each feature is only an example of a series of equivalent or similar features.
[0016] like Figure 1 , 23, a cold grinding conveying platform blocking device comprises a fixed frame 1, a rotating frame 2 is installed in the fixed frame 1, a first rotating shaft 5 is arranged at the upper end position of the rotating frame 2 near the rear end and is connected to the fixed frame 1 through the first rotating shaft 5, a return spring 13 is sleeved on the first rotating shaft 5, a limit strip 12 is arranged obliquely below the first rotating shaft 5, a resisting strip 11 is arranged on the fixed frame 1, and the resisting strip 11 is arranged obliquely above the limit strip 12, and one end of the return spring 13 resists against On the limit bar 12, the other end of the return spring 13 is pressed under the resisting bar 11, a fixed plate 14 is arranged near the rear end position in the rotating frame 2, the rear end of the fixed plate 14 is connected with a cylinder 4, a screw 8 is arranged on the fixed plate 14, a moving block 7 is arranged at the front end of the screw 8, the moving block 7 is installed in the rotating frame 2, a limit stop rod 6 is arranged at the front end of the moving block 7, a second rotating shaft 10 is arranged on the limit stop rod 6 and is connected to the rotating frame 2 through the second rotating shaft 10.
[0017] A damping spring 9 is arranged between the limit stop rod 6 and the moving block 7 , one end of the damping spring 9 is connected to the limit stop rod 6 , and the other end of the damping spring 9 is connected to the moving block 7 .
[0018] Sliding protrusions are arranged on both sides of the moving block 7 .
[0019] The left and right side walls of the rotating frame 7 are both provided with sliding grooves 3 for the sliding protrusions to move.
[0020] During use, the cylinder 4 pushes the fixed plate 14 forward, thereby driving the rotating frame 2 to rotate upward with the first rotating shaft 5 as the rotating point, so that the limit stop rod 6 is lifted upward, thereby achieving blocking.
[0021] If it is necessary to adjust the lifting angle of the limit stop rod 6, the screw rod 8 can be rotated so that the screw rod 8 pushes the moving block 7 forward or pulls the moving block 7 backward. When the moving block 7 moves forward, the limit stop rod 6 is pushed to rotate downward with the second rotating shaft 10 as the rotating point, thereby reducing the lifting height of the limit stop rod 6. Conversely, when the moving block 7 moves backward, the limit stop rod 6 is pulled to rotate upward with the second rotating shaft 10 as the rotating point, thereby increasing the lifting height of the limit stop rod 6.
[0022] The damping spring 9 can provide a damping effect when the product hits the limit stopper rod 6 .
[0023] The cooperation between the sliding protrusion and the slide groove 3 can facilitate the stable forward and backward movement of the moving block 7 on the one hand, and can also limit the maximum moving distance of the moving block 7 on the other hand.
[0024] The reset spring 13 can enable the rotating frame 2 to rotate downward with the first rotating shaft 5 as the rotating point when the cylinder no longer pushes the fixed plate 14 forward, so as to quickly reset.
[0025] The beneficial effects of the utility model are as follows: the utility model has reasonable structural design and is easy to use, and can facilitate the rapid pushing up or retracting of the limit stopper rod, and can also facilitate the adjustment of the lifting height of the limit stopper rod, thereby improving the convenience and flexibility of using the limit stopper rod.
[0026] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
