Description

Technical Field

[0001] This invention belongs to the field of threaded assembly, and specifically relates to a thread tightening device for a guidance cabin. Background Technology

[0002] Currently, when threading the head cone and navigation cabin of a certain product, the material properties of the two parts differ significantly. The high-density alloy part is weakly magnetic, heavy, hard, and has strong cutting properties; the hard aluminum alloy part is large, heavy, and has low hardness. Furthermore, the connection between the two is a large-size threaded connection with a second-level precision. Typically, manual tightening is used. This manual method is time-consuming, labor-intensive, and prone to thread locking, resulting in high rework costs, low assembly efficiency, poor process economy, and certain operational safety hazards. Summary of the Invention

[0005] (II) Technical Solution

[0006] To solve the above-mentioned technical problems, the present invention proposes a threaded tightening device for a guidance cabin, comprising: a base 1, a support frame 2, a side plate 3, an upper support plate 4, a screw 5, an upper hanging seat 6, and a support plate 10.

[0007] The base 1 is configured as a ring structure. Side plates 3 are vertically provided on both sides of the base 1. The tops of the two side plates 3 are connected by an upper support plate 4. The upper support plate 4 has a hole in the middle, and a screw 5 is inserted downward through the hole. An upper hanging seat 6 is provided below the upper support plate 4. The upper hanging seat 6 is coaxially arranged with the screw 5 and is sleeved on the outside of the screw 5. A support frame 2 is connected to the outside of the upper hanging seat 6. The support frame 2 is configured as a conical frustum structure, narrow at the top and wide at the bottom. Two grooves are symmetrically provided on the outer side wall of the bottom ring. A support plate 10 is provided in the groove. A pin hole is provided above the groove.

[0008] Place the large end face of workpiece b8 horizontally on the operating platform, place workpiece a7 on the small end face of workpiece b8, and insert base 1 from the top of workpiece a7 downwards, so that the inner arc surface of base 1 fits against the outer arc surface of workpiece b8. Apply slight downward force until the two arc surfaces are completely matched and fixed stably.

[0009] Twist the support frame 2 clockwise until its groove is lower than the bottom surface of the workpiece a7, and insert the two support plates 10 into the grooves on both sides of the support frame 2 respectively, so that the support plates 10 are fixed on the support frame 2.

[0010] Twist upwards until the upper end face of the support plate 10 contacts the lower end face of the workpiece a7. Continue to rotate the support 2 upwards to lift the head cone of the workpiece a7. When the pin holes on both sides are aligned with the process holes of the workpiece a7, turn the support 2 clockwise until it is tightened to the root of the thread of the workpiece b8. Remove the fixed support plate 10 and then take the fixture out from the bottom to the top along the outer end of the workpiece a7.

[0011] The screw 5 and workpiece a7, as well as workpiece a7 and workpiece b8, are driven by the same pitch thread.

[0012] The support frame 2 has a through hole in the vertical direction on the upper ring surface of the bottom ring. The support plate 10 has a through hole of the same size as the support frame 2. After the support plate 10 is inserted into the groove of the support frame 2, the hole is aligned with the corresponding hole on the support frame, and the pin 9 is inserted into the hole respectively.

[0013] The base 1 has a gasket 12 bonded to its inner arc surface, which is attached to the outer arc surface of the workpiece b8.

[0014] When the pin holes on both sides of the support frame are aligned with the process holes of the workpiece a7, stop screwing and insert pin 11 to prevent relative movement between the workpiece a7 and the support frame 10 during screwing.

[0015] The support frame 2 and the support plate 10 are provided with four through holes, and each through hole is provided with a pin 9 to prevent the support frame 2 and the support plate 10 from sliding relative to each other.

[0022] The base 1 is configured as a ring structure. Side plates 3 are vertically provided on both sides of the base 1. The tops of the two side plates 3 are connected by an upper support plate 4. The upper support plate 4 has a hole in the middle, and a screw 5 is inserted downward through the hole. An upper hanging seat 6 is provided below the upper support plate 4. The upper hanging seat 6 is coaxially arranged with the screw 5 and is sleeved on the outside of the screw 5. A support frame 2 is connected to the outside of the upper hanging seat 6. The support frame 2 is configured as a conical frustum structure, narrow at the top and wide at the bottom. Two grooves are symmetrically provided on the outer side wall of the bottom ring. A support plate 10 is provided in the groove. A pin hole is provided above the groove.

[0023] Place the large end face of workpiece b8 horizontally on the operating platform, place workpiece a7 on the small end face of workpiece b8, and insert base 1 from the top of workpiece a7 downwards, so that the inner arc surface of base 1 fits against the outer arc surface of workpiece b8. Apply slight downward force until the two arc surfaces are completely matched and fixed stably.

[0024] Twist the support frame 2 clockwise until its groove is lower than the bottom surface of the workpiece a7, and insert the two support plates 10 into the grooves on both sides of the support frame 2 respectively, so that the support plates 10 are fixed on the support frame 2.

[0025] Twist upwards until the upper end face of the support plate 10 contacts the lower end face of the workpiece a7. Continue to rotate the support 2 upwards to lift the head cone of the workpiece a7. When the pin holes on both sides are aligned with the process holes of the workpiece a7, turn the support 2 clockwise until it is tightened to the root of the thread of the workpiece b8. Remove the fixed support plate 10 and then take the fixture out from the bottom to the top along the outer end of the workpiece a7.

[0026] The screw 5 and workpiece a7, as well as workpiece a7 and workpiece b8, are driven by the same pitch thread.

[0027] The support frame 2 has a through hole in the vertical direction on the upper ring surface of the bottom ring. The support plate 10 has a through hole of the same size as the support frame 2. After the support plate 10 is inserted into the groove of the support frame 2, the hole is aligned with the corresponding hole on the support frame, and the pin 9 is inserted into the hole respectively.

[0028] The base 1 has a gasket 12 bonded to its inner arc surface, which is attached to the outer arc surface of the workpiece b8.

[0029] When the pin holes on both sides of the support frame are aligned with the process holes of the workpiece a7, stop screwing and insert pin 11 to prevent relative movement between the workpiece a7 and the support frame 10 during screwing.

[0030] The support frame 2 and the support plate 10 are provided with four through holes, and each through hole is provided with a pin 9 to prevent the support frame 2 and the support plate 10 from sliding relative to each other.

[0031] This device can achieve synchronous up-and-down rotation of the double threads with the same pitch between the device and the workpiece, quick insertion and support positioning of the pallet, and quick disassembly and restoration of the pallet, thus realizing the workpiece being screwed into place in one go.

[0032] Secondly, it can realize cage-type rotation protection for workpiece hoisting, which can prevent the lock-up when the thread is tightened due to large force, and also protect the operator from injury.

[0033] Thirdly, it can achieve self-centering fixation of the conical base, allowing for quick loading and unloading, flexible placement and removal, and convenient use.

[0034] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
