Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0020] The technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] Consisting of Figure 1 , Figure 2 , Figure 3 and Figure 4 as shown, the present utility model provides the following technical solution: A feeding mechanism for a spark plug and an injector spacer sleeve, including a bottom plate 1. On the top of the bottom plate 1, a driving gear 2 and a driven gear 3 are symmetrically installed. The driving gear 2 and the driven gear 3 are connected by a transmission chain 5. On the back of the bottom plate 1, a driving motor 4传动连接 with the driving gear 2 is installed. On the transmission chain 5, a feeding rack 6 is installed at equal intervals. The raw material of the spacer sleeve is placed between three positioning frames 63. The three positioning frames 63 play a role of three-point clamping and positioning for the raw material of the spacer sleeve. Then the driving motor 4 works, driving the driving gear 2 to rotate. Cooperating with the provided driven gear 3, it drives the transmission chain 5 to rotate on the top of the bottom plate 1, thereby driving the feeding rack 6 to rotate on the top of the bottom plate 1, realizing the automatic feeding of the raw material of the spacer sleeve, automatically conveying the raw material of the spacer sleeve to a predetermined position, and improving the feeding efficiency.

[0022] Preferably, the feeding rack 6 includes a base 61 installed on the transmission chain 5 at equal intervals. On the top of the base 61, a top plate 62 is installed. Between the base 61 and the top plate 62, a spacing adjustment module 64 is installed. On the spacing adjustment module 64, a positioning frame 63 is installed. The three positioning frames 63 play a role of three-point clamping and positioning for the raw material of the spacer sleeve.

[0023] Preferably, three positioning frames 63 are provided, and the three positioning frames 63 are distributed in a "pin" shape on the top of the top plate 62 for three-point positioning.

[0024] Preferably, the spacing adjustment module 64 includes a turntable 644 rotating between the base 61 and the top plate 62, the turntable 644 is provided with driving grooves 646 at equal intervals, the top plate 62 is provided with a guide groove 641, a driving block 647 is slidably provided inside the driving groove 646, a positioning frame 63 passing through the guide groove 641 is installed on the top of the driving block 647, a gear ring 645 is fixed on the outer periphery of the turntable 644, the gear ring 645 is meshedly connected with the first gear 642 inside the base 61, and a positioning frame 63 passing through the base 61 is installed on the top of the first gear 642 When it is necessary to feed raw materials of spacers of different sizes, the driving rod 643 is rotated by a tool to drive the first gear 642 to rotate, thereby driving the gear ring 645 to rotate, and then synchronously driving the turntable 644 to rotate. Since the guide groove 641 plays a guiding and limiting role for the positioning frame 63, the driving block 647 is driven to slide inside the driving groove 646 during the rotation of the turntable 644, thereby realizing the rapid adjustment of the distance between the three positioning frames 63, so that it can be used to position the raw materials of spacers of different sizes, thereby improving the convenience of use.

[0025] Preferably, an annular guide rail 7 is fixed around the top of the base plate 1, and the loading rack 6 slides on the inner wall of the annular guide rail 7 through a slider 8 on the side. The setting of the annular guide rail 7 and the slider 8 guides and limits the movement of the loading rack 6.

[0026] Working principle:

[0027] The raw materials of the spacer are placed between the three positioning frames 63. The three positioning frames 63 play a three-point clamping and positioning role on the raw materials of the spacer. Then the active motor 4 works to drive the active gear 2 to rotate, and cooperates with the set driven gear 3 to drive the transmission chain 5 to rotate on the top of the bottom plate 1, thereby driving the loading frame 6 to rotate on the top of the bottom plate 1, realizing automatic loading of the raw materials of the spacer, and automatically transporting the raw materials of the spacer to the predetermined position, thereby improving the loading efficiency;

[0028] When it is necessary to load raw materials of spacers of different sizes, use a tool to rotate the drive rod 643, which drives the first gear 642 to rotate, thereby driving the gear ring 645 to rotate, and then synchronously drives the turntable 644 to rotate. Since the guide groove 641 plays a guiding and limiting role on the positioning frame 63, the drive block 647 is driven to slide inside the drive groove 646 during the rotation of the turntable 644, thereby realizing the rapid adjustment of the distance between the three positioning frames 63, so that it can be used to position the raw materials of spacers of different sizes, thereby improving the convenience of use.
