Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transmission pin driving, in particular to a pin sleeve structure for preventing pins from deforming and failing. Background Art
[0002] At present, there is a gap in the driving form of the transmission pin, and the gap between the pin and the pin hole is large. Therefore, when the movement speed of the mechanical equipment is too high, there will be a large impact during its start and stop, which will cause the pin to deform, resulting in drive failure and affecting the use of the equipment. Therefore, a pin sleeve structure is proposed to prevent the pin from deforming and failing. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a pin sleeve structure that prevents pins from deforming and failing, thereby solving the problems raised in the above-mentioned background technology.
[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a pin sleeve structure for preventing pin deformation and failure, comprising a first driving part and a second driving part, wherein a pin body is inserted into the interior of the first driving part, a driving pin hole is opened on one side of the second driving part and at one end of the pin body, a detection sleeve is installed inside the driving pin hole, a pin sleeve body is installed on the inner side of the detection sleeve, and one end of the pin body passes through the pin sleeve body and extends to the interior of the driving pin hole.
[0005] Preferably, there is an interference fit with no gap between the pin sleeve body and the detection sleeve.
[0006] Preferably, a plurality of monitoring sensors are provided on the inner side of the detection sleeve and on the outer side of the pin sleeve body.
[0007] Preferably, wireless sensors are integrated in the monitoring sensors, and the monitoring sensors are connected to an external controller via the wireless sensors.
[0008] Preferably, a wear-resistant sleeve is provided on the outer side of the pin sleeve body.
[0009] The utility model provides a pin sleeve structure for preventing pin deformation and failure, which has the following beneficial effects:
[0010] 1. The pin sleeve structure for preventing the pin from deforming and failing is provided with a pin sleeve body, a driving pin hole and a pin body. The pin sleeve body is installed into the driving pin hole through interference fit, so that the pin sleeve body is located on the inner side of the detection sleeve, so that the pin sleeve body and the wear-resistant sleeve have an interference fit without gap, and then the pin body passes through the wear-resistant sleeve and is inserted into the driving pin hole. When the equipment is moving at high speed, at the moment of starting and stopping, the pin body and the driving pin hole are assembled with a small gap, and the gap is small, so that the impact generated during movement is small. The pin sleeve body adopts a buffering material, so that when the pin sleeve body is impacted, it can play a buffering role during the impact, thereby effectively preventing the pin body from deforming and failing.
[0011] 2. The pin sleeve structure for preventing the pin from deforming and failing is provided with a wear-resistant sleeve, a monitoring sensor and a detection sleeve. The monitoring sensor detects the impact force applied by the pin body to the pin sleeve body. If the pin sleeve body can buffer normally, the detected impact force is smaller than the pin sleeve body that cannot buffer normally due to aging. The detected impact force is transmitted to the external controller through the wireless transmission module to obtain the detection result and send an alarm to the staff so that the staff can replace the pin sleeve body in time.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0017] See also Figures 1 to 3The utility model provides a technical solution: a pin sleeve structure for preventing pin deformation and failure, comprising a first driving part 1 and a second driving part 2, wherein a pin body 8 is inserted into the interior of the first driving part 1, a driving pin hole 3 is opened on one side of the second driving part 2 and at one end of the pin body 8, a detection sleeve 6 is installed inside the driving pin hole 3, a pin sleeve body 4 is installed on the inner side of the detection sleeve 6, and one end of the pin body 8 passes through the pin sleeve body 4 and extends to the interior of the driving pin hole 3.
[0018] There is an interference fit between the pin sleeve body 4 and the detection sleeve 6 without any gap. A number of monitoring sensors 7 are provided on the inner side of the detection sleeve 6 and on the outer side of the pin sleeve body 4 to monitor whether there is any problem with the pin sleeve body 4. Wireless sensors are integrated in the monitoring sensors 7. The monitoring sensors 7 are connected to the external controller 9 via the wireless sensors to analyze the data collected by the monitoring sensors 7. A wear-resistant sleeve 5 is provided on the outer side of the pin sleeve body 4 to reduce the wear of the pin sleeve body 4.
[0019] In summary, the pin sleeve structure that prevents the pin from deforming and failing, when in use, the pin sleeve body 4 is installed into the driving pin hole 3 through interference fit, so that the pin sleeve body 4 is located on the inner side of the detection sleeve 6, so that the pin sleeve body 4 and the wear-resistant sleeve 5 are interference fit without gap, and then the pin body 8 passes through the wear-resistant sleeve 5 and is inserted into the driving pin hole 3. When the equipment is moving at high speed, at the moment of starting and stopping, because there is a small gap between the pin body 8 and the driving pin hole 3, the gap is small, so that the impact generated during movement is small. The pin sleeve body 4 can adopt non-metallic materials such as POM, PTFE, PEEK, etc. according to different working temperatures, so that the pin sleeve body 4 can play a buffering role when it is impacted. The impact force applied to the pin sleeve body 4 by the pin body 8 is detected by the monitoring sensor 7. If the pin sleeve body 4 can buffer normally, the detected impact force is less than the pin sleeve body 4 cannot buffer normally. The detected impact force is transmitted to the external controller 9 through the wireless transmission module to obtain the detection result and issue an alarm prompt to the staff.
