Description

Technical Field

[0001] This utility model belongs to the field of sensor press-fitting technology, specifically relating to a press-fitting mechanism for a protective cover and a sleeve. Background Technology

[0002] A sensor is a device that can sense and measure changes in physical, chemical, or biological parameters and convert them into readable or processable signals. Sensors require a protective shield on their outside to protect the internal chips and components, which requires pressing the shield against a sleeve that houses the chips and components.

[0003] In existing sensors, the protective cover and sleeve need to be clamped and positioned separately during press-fitting, which is cumbersome and inefficient. Moreover, after press-fitting, manual unloading is often required, which further reduces the efficiency of press-fitting.

[0004] Therefore, a protective cover and sleeve pressing mechanism is proposed. Summary of the Invention

[0005] This utility model provides a protective cover and sleeve pressing mechanism, the purpose of which is to solve the problems mentioned above.

[0006] This utility model embodiment provides a cover and sleeve pressing mechanism, including a base; a bracket located at the center of one outer wall of the base; an electric push rod located at the top of the bracket; a pressing ring fixed to the output end of the electric push rod; a first stepper motor located at the center of the top of the base; a rotating disk fixed to the output end of the first stepper motor; a second stepper motor located on the outer wall of the rotating disk; a flip plate fixed to the output end of the second stepper motor; and a guide pressing assembly located on the flip plate. The guide pressing assembly includes: a guide post located at the center of the top of the flip plate; a lower guide platform and an upper guide platform located on the outer wall of the guide post, the lower guide platform being below the upper guide platform; a rod hole penetrating the bottom of the flip plate; a vertical rod penetrating the rod hole; a disc located at the bottom end of the vertical rod; a spring located between the disc and the flip plate; and an outer guide sleeve located at the top end of the vertical rod.

[0007] Furthermore, a second spring is provided at the top of the flip plate near the outer side of the lower guide platform, a feeding push ring is provided at the top of the second spring, a protective cover is provided above the feeding push ring, and a sleeve is provided above the protective cover.

[0008] Furthermore, a groove is provided on the outer wall of the rotating disk near the outer side of the flip plate, allowing it to rotate.

[0009] Furthermore, the outer diameter of the press-fit ring is smaller than the inner diameter of the protective cover.

[0010] Furthermore, the flip plate and the groove are rotatably connected.

[0011] Furthermore, both the lower guide platform and the upper guide platform have annular inclined surfaces on their tops.

[0012] Furthermore, the inner wall of the outer guide sleeve is tightly fitted to the outer wall of the lower guide platform.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model can not only achieve rapid positioning of the cover and sleeve on the sensor through the guide pressing assembly, without the need for traditional clamps to perform clamping and positioning operations, making the operation simpler and more convenient, but also achieve pressing of the cover and sleeve under continuous positioning, ensuring the quality of pressing.

[0015] 2. This utility model uses a feeding pusher ring to push the pressed protective cover and sleeve away from the outer guide sleeve, facilitating the free fall of the protective cover and sleeve. The rotation of the flip plate causes the protective cover and sleeve to fall downwards, achieving automatic feeding with high efficiency. The rotating disc allows for switching between workstations, and in conjunction with the automatic feeding mechanism, it can achieve automatic feeding, automatic pressing, and automatic unloading of the protective cover and sleeve, resulting in a high degree of automation.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5This utility model embodiment proposes a protective cover and sleeve pressing mechanism, including a base 1. A bracket 2 is provided at the center of one side of the outer wall of the base 1. An electric push rod 3 is provided at the top of the bracket 2. A pressing ring 4 is fixedly connected to the output end of the electric push rod 3. A stepper motor 5 is provided at the center of the top of the base 1. A rotating disk 6 is fixedly connected to the stepper motor 5 at the output end of the stepper motor 5. Four stepper motors 7 are axially arranged on the outer side of the rotating disk 6. Each of the four stepper motors 7 is fixedly connected to a flipping plate 8 at the output end of the stepper motor 7. A groove 14 is provided on the outer side of the rotating disk 6 near the outer side of the flipping plate 8 for rotation. The flipping plate 8 and the groove 14 are rotatably connected to each other to ensure the stability of the rotation of the flipping plate 8. A guide is provided at the center of the top of the flipping plate 8. The guide post 91 in the press assembly 9 has a lower guide platform 92 and an upper guide platform 93 on its outer side wall. The top of the lower guide platform 92 and the upper guide platform 93 are both provided with annular inclined surfaces, which can guide the sleeved cover 12 and sleeve 13 to move smoothly downward. The lower guide platform 92 is located below the upper guide platform 93. The bottom of the flip plate 8 has a rod hole 94 through it. A vertical rod 95 passes through the inside of the rod hole 94. A disc 96 is provided at the bottom of the vertical rod 95. A spring 97 is provided between the top of the disc 96 and the bottom of the flip plate 8 near the outer side of the vertical rod 95. An outer guide sleeve 98 is provided at the top of the vertical rod 95. The inner side wall of the outer guide sleeve 98 is tightly attached to the outer side wall of the lower guide platform 92 to form a whole and position the cover 12.

[0027] In order to achieve rapid positioning and pressing of the protective cover 12 and the sleeve 13, in this embodiment, the protective cover 12 is first placed on the outside of the guide post 91. Under the action of gravity, the protective cover 12 moves downward along the guide post 91 and is placed on the outside of the outer guide sleeve 98. The outer guide sleeve 98 is used to position the protective cover 12 axially.

[0028] Then, sleeve 13 is placed on the outside of guide post 91. Under the action of gravity, sleeve 13 moves down along guide post 91 and is placed on the outside of upper guide platform 93. Upper guide platform 93 is used to axially position sleeve 13. Since no press fitting is performed, sleeve 13 is located above protective cover 12.

[0029] Finally, the control electric push rod 3 drives the pressing ring 4 to move downward through its output end on one side. During the movement, the pressing ring 4 moves along the outside of the guide post 91, the lower guide platform 92 and the upper guide platform 93. After the pressing ring 4 contacts the sleeve 13, it presses it downward. As the sleeve 13 moves downward, the sleeve 13 presses the outer guide sleeve 98 downward. At this time, the lower guide platform 92 is exposed, providing space for the movement of the sleeve 13. Under pressure, the sleeve 13 is pressed into the inside of the protective cover 12, completing the pressing between the sleeve 13 and the protective cover 12.

[0030] Furthermore, as the outer guide sleeve 98 moves downward, the vertical rod 95 at the bottom of the outer guide sleeve 98 moves synchronously, and the spring 97 is stretched, using the deformation potential energy of the spring 97 to provide kinetic energy for the subsequent upward movement and reset of the outer guide sleeve 98.

[0031] Example 2

[0032] Reference Figure 1-5 This utility model embodiment also proposes a protective cover and sleeve pressing mechanism, including a base 1, a bracket 2 is provided at the center of one side outer wall of the base 1, an electric push rod 3 is provided at the top of the bracket 2, a pressing ring 4 is fixedly connected to the electric push rod 3 through its output end on one side, a stepper motor 5 is provided at the center of the top of the base 1, a rotating disk 6 is fixedly connected to the stepper motor 5 through its output end on one side, four stepper motors 7 are axially arranged on the outer side wall of the rotating disk 6, a flipping plate 8 is fixedly connected to the four stepper motors 7 through their output ends on one side, a spring 10 is provided at the top of the flipping plate 8, a feeding push ring 11 is provided at the top of the spring 10, a protective cover 12 is provided above the feeding push ring 11, the outer diameter of the pressing ring 4 is smaller than the inner diameter of the protective cover 12, and a sleeve 13 is provided above the protective cover 12.

[0033] To achieve automatic unloading of the press-fitted protective cover 12 and sleeve 13, as the protective cover 12 and sleeve 13 are press-fitted, the unloading push ring 11 is pressed downward. At this time, the spring 10 at the bottom of the unloading push ring 11 is compressed. When the press-fitting ring 4 returns to its original position and moves upward, the deformation potential energy of the spring 10 pushes the unloading push ring 11 upward. The protective cover 12 and sleeve 13 above the unloading push ring 11 are pushed, and the stepper motor 7 drives the flipping plate 8 to rotate through its output end on one side. As the flipping plate 8 flips, the guide press-fitting assembly 9 on the flipping plate 8 gradually faces downward. Under the action of gravity, the press-fitted protective cover 12 and sleeve 13 fall down by themselves, realizing automatic unloading.
