Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, when adjusting the spark plug, the factors affected by human factors are relatively large during the adjustment process, and the electrodes on the side of the spark plug are easy to break. Rotate, so that the side pole of the spark plug to be adjusted by the jacking actuator rod can be continuously and effectively tapped and jacked up, which not only avoids the influence of human factors, but is also conducive to the standardization of operations, and at the same time, the use of machinery instead of traditional labor effectively improves the work efficiency. efficiency

Embodiment 1

[0025] Such as figure 1 image 3 and Figure 4 As shown, the spark plug gap adjustment equipment includes a support frame 1, a telescopic jacking mechanism is fixed on the support frame 1 and a spark plug fixing mechanism 13 is arranged directly below the telescopic jacking mechanism; Ear 2, the telescopic jacking mechanism includes a crankshaft 3 arranged horizontally. The first connecting rod 5, the other end of the first connecting rod 5 that is relatively sleeved on the journal end is connected to the second connecting rod 6 through a universal joint, and the second connecting rod 6 is connected to the other end of the first connecting rod 5 through The universal shaft coupling is connected with a top-holding actuator rod 7, and the support frame 1 is fixed with a vertical guide sleeve 8, and the top-holding actuator rod 7 is guided into the guide sleeve 8. When the spark plug is fixed by the spark plug fixing mechanism, and the telescopic top is used When it is adjuste...

Embodiment 2

[0028] Such as figure 1 , image 3 and Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that two sliding rails 9 parallel to each other and at the same level are horizontally provided on the support frame 1, and the axial direction of the sliding rails 9 is parallel to the direction of the crankshaft 3. In the axial direction, the longitudinal section of the slide rail 9 is a structure with a small top and a large bottom. Threaded hole, the threaded hole is provided with its matching lead screw 11, when the lead screw 11 rotates, the slide plate 10 can slide on the slide rail 9, the lifting lug 2 hangs upside down on the lower surface of the slide plate 10; on the support frame 1 A second drive motor 12 for driving the lead screw 11 to rotate is provided. By setting the sliding plate 10, the flexible control of the lowest position of the jacking actuator rod 7 is realized, thereby further broadening the application range of the device and impro...

Embodiment 3

[0030] Such as Figure 1 to Figure 4 As shown, the difference between this embodiment and Embodiment 2 is that the support frame 1 is also provided with a horizontal conveyor belt 15, several spark plug fixing mechanisms 13 are evenly distributed on the conveyor belt 15, and the support frame 1 is also provided with A horizontal conveyor belt support plate 17 , the conveyor belt 15 is arranged around the conveyor belt support plate 17 , and a section of the conveyor belt 15 above the conveyor belt support plate 17 is supported by the conveyor belt support plate 17 . The staff can install other spark plugs in sequence along the direction of the transmission belt, so that the time is fully utilized, and the work efficiency of the staff is doubled by adding the transmission belt. One move ", adopt stepper motor for the driving of transmission belt among the present invention.

[0031] During use, the inventors found that due to the small size of the side electrode of the spark p...

Abstract

The invention discloses a spark plug gap adjusting device, and the device comprises a supporting frame, and a telescopic jacking mechanism and a spark plug fixing mechanism arranged under the telescopic jacking mechanism are fixed to the supporting frame; a pair of lifting lugs are arranged on the supporting frame in the horizontal direction at intervals. The telescopic jacking mechanism comprises a crankshaft which is horizontally arranged; two ends of the crankshaft are respectively guided into the lifting lugs; a first driving motor is fixed at one end of the crankshaft; the journal of the crankshaft is sleeved with a first connecting rod; the other end, opposite to the end sleeving the journal, of the first connecting rod is connected with a second connecting rod through a universal coupling; the other end, opposite to the end connected with the first connecting rod, of the second connecting rod is connected with a jacking execution rod through a universal coupling; a guide sleeve matched with the execution rod is fixed outside the ejection execution rod, the guide sleeve is vertically arranged and fixed to the supporting frame, and when the spark plug is fixed through the spark plug fixing mechanism, the arc face of the side electrode of the spark plug directly faces the lower end of the ejection execution rod.

Description

technical field [0001] The invention relates to the field of spark plug top pressure regulating devices, in particular to spark plug gap regulating equipment. Background technique [0002] Spark plugs are widely used in various fields of modern production and life, including the aviation field, which requires high flashover strength and stability of spark plugs. In order to ensure the flashover strength and stability of the work, the aviation spark plug adopts the multi-side electrode type compared with the ordinary spark plug, that is, multiple side electrodes are evenly distributed outside the center positive electrode, and the two side electrode type is the most widely used. [0003] During the use of two-pole spark plugs, the degree of ablation on both sides is different, and the gaps from the center will be different. Due to the generation of gaps, the size of flashover on each side will be changed, and the expansion of the gap will be aggravated, which will eventually ...
