Description

Technical Field

[0001] This invention relates to the field of chassis assembly technology, specifically to an auxiliary device for assembling small chassis for electronic devices. Background Technology

[0002] Radar is a highly complex electronic device that spans multiple fields, including land, sea, air, and space. A single radar system consists of numerous electronic devices. With the trend towards miniaturization and compactness, the density of components in radar equipment is increasing. Among these components, small electronic enclosures are a crucial part of radar equipment and also constitute the largest variety and number of complete units. These enclosures are no more than 1 meter in size but are extremely dense, including structural parts, components, parts, and cables, and typically weigh between 40 kg and 60 kg.

[0003] When assembling these small chassis, operators typically need to move the chassis to a workbench to complete a series of assembly tasks, including component assembly, component soldering, structural assembly, and cable routing. Due to the high density of the chassis, operators need to rotate the chassis multiple times according to the assembly process to complete the operation from the optimal assembly perspective. Especially during cable routing assembly, the chassis rotates very frequently. However, the chassis is relatively heavy, and it is time-consuming and laborious for operators to rotate it. Repeated rotations can wear down the surface of the chassis, causing cosmetic damage. There is also a risk of the chassis falling, posing a risk of personal injury and potential quality issues.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Please see Figure 1-7 The present invention provides the following technical solution: an auxiliary device for assembling a small chassis for electronic devices, including a chassis 1, a workbench 2, a frustum 3, a bearing cylinder 4, a pin fastener 5, and a slider fastener 7, wherein the frustum 3 is fixed on the top of the workbench 2, and the bearing cylinder 4 is sleeved on and rotatably mounted on the frustum 3.

[0032] The chassis 1 is placed on top of the bearing cylinder 4. To facilitate the rotation of the chassis 1, the top of the truncated cone 3 is provided with several semi-circular grooves 8, and steel balls 9 are placed inside the semi-circular grooves 8. The top of the inner cavity of the bearing cylinder 4 is in contact with the outer surface of the steel balls 9. Several vertical rollers 10 are evenly spaced and rotated around the outer periphery of the truncated cone 3. The inner wall of the bearing cylinder 4 is in contact with the outer surface of the several vertical rollers 10.

[0033] As a preferred embodiment, in order to facilitate the positioning of the bearing cylinder 4, the pin fastener 5 includes a mounting plate 11, which is fixedly connected to the top of the workbench 2 by bolts. A vertical plate 12 is fixedly connected to the top of the mounting plate 11. A pin 13 is slidably installed through one side of the vertical plate 12. One end of the pin 13 is fixedly connected to an insert plate 14. Several slots 16 are opened on the outer periphery of the bearing cylinder 4. The slots 16 are evenly distributed on the outer periphery of the bearing cylinder 4, and the slots 16 are used in conjunction with the insert plate 14. A first spring 15 is sleeved on the outer periphery of the pin 13, and the two ends of the first spring 15 are fixedly connected to the opposite side of the insert plate 14 and the vertical plate 12, respectively.

[0034] As a preferred embodiment, in order to facilitate the rotation adjustment of the bearing cylinder 4, a connecting plate 17 is fixedly connected to the other end of the pin 13. A positioning rod 18 is fixedly connected to the side of the connecting plate 17 near the vertical plate 12. A first positioning hole 19 and a second positioning hole 20 are provided on the surface of the vertical plate 12. Both the first positioning hole 19 and the second positioning hole 20 are used in conjunction with the positioning rod 18. The first positioning hole 19 is located directly above the pin 13, and the second positioning hole 20 is located directly behind the pin 13.

[0035] As a preferred embodiment, to facilitate the fixing of the chassis 1, the top of the bearing cylinder 4 is provided with several stepped grooves 6 arranged in a warp and weft pattern, and the two stepped grooves 6 are connected to each other. Several slider fasteners 7 are provided, all of which are slidably installed in the stepped grooves 6. The several slider fasteners 7 are respectively arranged on the outer periphery of the chassis 1 for positioning the chassis 1. Specifically, the slider fastener 7 includes a stepped slider 21, which is slidably installed inside the stepped groove 6. The top of the stepped slider 21 is fixedly connected to two first right-angled trapezoidal plates 22. A housing 23 is fitted and slidably installed on the outer periphery. Inside the housing 23, a pressing plate 25 is fixedly connected via a second spring 24. A second right-angled trapezoidal plate 26 is fixedly connected to both sides of the pressing plate 25. The inclined surface of the first right-angled trapezoidal plate 22 slides in contact with the inclined surface of the second right-angled trapezoidal plate 26. A fastening screw 27 is rotatably installed on the top of the stepped slider 21 via a bearing. The top end of the fastening screw 27 passes through the housing 23 and is fixedly connected to a knob head 28. To prevent the pressing plate 25 from directly contacting the chassis 1 and causing friction damage, a rubber plate 29 is fixedly connected to the side of the pressing plate 25 closest to the chassis 1.

[0036] In use, place the housing 1 at the top center of the bearing cylinder 4, slide the stepped slider 21 along the stepped groove 6 so that one side of the rubber plate 29 is close to the housing 1, and then rotate the knob head 28. The knob head 28 drives the fastening screw 27 to rotate, and the fastening screw 27 drives the sleeve 23 to move downward. The sleeve 23 presses the second right-angled trapezoidal plate 26 downward. The second right-angled trapezoidal plate 26 is guided by the inclined surface of the first right-angled trapezoidal plate 22, pushing the extrusion plate 25 to move closer to the housing 1 until the extrusion plate 25 pushes the rubber plate 29 to limit the housing 1. During the process, the extrusion plate 25 stretches the second spring 24. The stretching of the second spring 24 can realize the automatic reset of the extrusion plate 25 when the knob head 28 is reversed.

[0037] When the bearing cylinder 4 needs to be rotated to make the chassis 1 rotate, the connecting plate 17 is pulled. The connecting plate 17 drives the pin 13 to make the insert plate 14 disengage from the slot 16. During the process, the insert plate 14 squeezes the first spring 15 until the positioning rod 18 disengages from the first positioning hole 19. The connecting plate 17 is rotated so that the positioning rod 18 is aligned and inserted into the second positioning hole 20. At this time, the insert plate 14 completes a ninety-degree rotation. Under the elastic force of the first spring 15, the insert plate 14 contacts the outer surface of the bearing cylinder 4, and the bearing cylinder 4 can be rotated.

[0038] When it is necessary to position the bearing cylinder 4, pull the connecting plate 17. The connecting plate 17 drives the positioning rod 18 to disengage from the second positioning hole 20. Rotate the connecting plate 17 so that the positioning rod 18 is aligned and inserted into the first positioning hole 19. At this time, the insert plate 14 completes a ninety-degree flip. Under the elastic force of the first spring 15, the insert plate 14 is inserted into the slot 16 to perform circumferential positioning of the bearing cylinder 4.
