In practical applications, since the second trimming station is provided with more mechanisms for removing the burr waste, the second trimming station lacks space available for arranging the conveyor chain, so that after the target engine block approaches the cylinder conveyor chain 1 under the driving of the cylinder conveyor chain 1, the cylinder conveyor chain 1 will have difficulty in further driving the target engine block into the second trimming station.
In order to solve the above-mentioned problems, a scheme of the present embodiment is correspondingly proposed to assist the target engine block by means of a corresponding mechanism. Specifically, the second telescopic device 6 and the third telescopic device 7 can be driving devices such as an air cylinder and a hydraulic cylinder which can be used for realizing reciprocating linear driving, and three hinge shafts between the second telescopic device 6, the third telescopic device 7 and the first auxiliary push rod 5 are parallel to each other, so that a triangle structure can be formed. As shown in fig. 3, the first booster 5 is in a non-pushed state in the initial state; after the target engine cylinder body passes through the area where the second telescopic device 6 is located under the driving of the cylinder body conveying chain 1, the movable part of the third telescopic device 7 can be extended to drive the second end of the first auxiliary push rod 5 to rotate in the direction away from the second telescopic device 6 until the first auxiliary push rod 5 is blocked on the conveying channel of the cylinder body conveying chain 1, as shown in fig. 4, at the moment, the first auxiliary push rod 5 is in a pushing state, and at the moment, the movable part of the second telescopic device 6 is extended again, so that the first auxiliary push rod 5 can be abutted with the target engine cylinder body in front and push the target engine cylinder body forwards into the second trimming station; when the target engine cylinder reaches the second finishing station, the movable part of the second telescopic device 6 is retracted, and meanwhile, the movable part of the third telescopic device 7 is retracted, so that the second end of the first auxiliary push rod 5 is driven to rotate along the direction close to the second telescopic device 6 until the first auxiliary push rod 5 is not blocked on the conveying channel of the cylinder conveying chain 1, as shown in fig. 3, at the moment, the first auxiliary push rod 5 is in a non-pushing state, and therefore the storage of the first auxiliary push rod 5 is completed, and the first auxiliary push rod 5 can be prevented from blocking the next target engine cylinder.

In order to solve the above-mentioned problems, a scheme of the present embodiment is correspondingly proposed to assist the target engine block by means of a corresponding mechanism. Specifically, the fourth telescopic device 9 and the fifth telescopic device 10 may be driving devices such as an air cylinder and a hydraulic cylinder, which can be used for realizing reciprocating linear driving, and three hinge shafts between the fourth telescopic device 9, the fifth telescopic device 10 and the second push rod 8 are parallel to each other, so as to form a triangle structure.

Further, referring to fig. 1, 2, 7 and 9, in the third embodiment, the striking claw 2021 includes a first claw body 20213 and a second claw body 20214, the second claw body 20214 is slidably connected to the first claw body 20213 in a direction away from the central axis of the gear 2013 in a radial direction, and the second claw body 20214 is provided with a guide boss 202141; the knocking mechanism 2 comprises a fixing seat 203, and a fixing part of an eighth telescopic device 2011 is connected to the fixing seat 203; the fixed seat 203 is provided with a guide chute 2031, and a guide boss 202141 is in sliding fit with the guide chute 2031; the guide chute 2031 has a first groove section 20311 and a second groove section 20312 connected end to end, the first groove section 20311 is arc-shaped, the center of the first groove section 20311 falls on the center axis of the gear 2013, the second groove section 20312 extends along a first path, and the first path has a split path extending in a direction away from the center axis of the gear 2013 in the radial direction.
In this embodiment, the second claw 20214 may be slidably connected to the first claw 20213 by means of a rail-slider fit, and the striking end is disposed on the second claw 20214; the guide boss 202141 may be provided in a cylindrical shape. As shown in fig. 9, in one knocking cycle, during the process that the knocking end of the knocking claw 2021 approaches the target engine cylinder, the guide boss 202141 is first slidably fitted in the first slot section 20311, and since the center of the first slot section 20311 falls on the central axis of the gear 2013, that is, the center of the first slot section 20311 falls on the rotation central axis of the knocking claw 2021, the first slot section 20311 does not drive the guide boss 202141 to move radially, and the second claw 20214 does not move relative to the first claw 20213 at this stage; when the knocking end of the knocking claw 2021 is about to contact with the target engine cylinder, the guiding boss 202141 slides into the second groove section 20312, and since the second groove section 20312 has a sub-path extending along a direction away from the central axis of the gear 2013, the sliding fit between the guiding boss 202141 and the second groove section 20312 will drive the second claw 20214 to move radially outwards relative to the first claw 20213, at this time, the knocking end on the second claw 20214 approaches the target engine cylinder along the tangential direction, and approaches the target engine cylinder along the radial direction, so that after the knocking end on the second claw 20214 contacts with the target engine cylinder, impact forces in two directions are applied to the surface of the target engine cylinder at the same time, wherein the forces in the tangential direction are more shearing actions on burrs, can better drop the surface of the target engine cylinder, and the forces in the radial direction are more pressing actions on burrs, which are helpful for pressing the fine knocking end on the target engine cylinder, so that the surface of the target engine cylinder is leveled again; through the cooperation between the protruding portion 20151 of the damping retaining ring 2015 and the recessed portion 20212 on the connecting through hole 20211 in the second embodiment, the contact time between the knocking end of the second claw 20214 and the target engine cylinder body can be further increased, so that the effect of flattening the burrs on the surface of the target engine cylinder body by the second claw 20214 is more remarkable.
Therefore, based on the contact mode of the knocking claw 2021 and the target engine block in the embodiment, fine burrs can be flattened on the surface of the target engine block better while the burrs are knocked off from the surface of the target engine block, so that the burr removing effect and the surface quality of the target engine block are further improved.
