Automobile engine cylinder block grabbing device

Abstract

The utility model discloses an automobile engine cylinder block grabbing device, and belongs to the technical field of whole automobile assembly. The clamping end on one side of the mechanical arm is fixedly connected with a cylinder body of the air cylinder, the movable end of the air cylinder is fixedly connected with the movable positioning pin, the movable positioning pin is arranged facing the clamping end on the other side of the mechanical arm, and the clamping block is fixed to the clamping end on the other side of the mechanical arm. An in-place sensor is fixed to a cylinder body of the air cylinder. And a fixed positioning pin is fixed on the clamping block. When a cylinder body is clamped, the air cylinder can push the movable positioning pin to move towards the cylinder body until the movable positioning pin is completely attached to the surface of the cylinder body, close fit between the positioning pin and the cylinder body is achieved, and therefore the stability of the cylinder body during clamping and falling is guaranteed, and the clamping force of the clamp is enhanced. Shaking and deviation of the cylinder body in the transferring process are effectively avoided, the accuracy of the position of the cylinder body is improved, and the production efficiency is improved.

Description

Technical Field

[0001] The utility model relates to a grabbing device for a cylinder body of an automobile engine, belonging to the technical field of whole vehicle assembly. Background Art

[0002] In the processes of clamping, transferring, numbering and scanning QR codes of automobile cylinder bodies, the accuracy of the cylinder body position directly affects the accuracy of subsequent processes and product quality.

[0003] Traditional cylinder fixtures usually use fixed positioning pins to position and fix the cylinder. The contact area between the fixed positioning pins and the cylinder is limited, which often leads to insufficient contact, which makes the cylinder prone to position deviation and misalignment of the pallet when clamping and placing. Especially when performing high-precision operations such as numbering, this position deviation will directly affect the accuracy and clarity of the numbering. Not only does it reduce production efficiency, it may also damage the equipment and increase production costs. Utility Model Content

[0004] In order to solve the problems existing in the background technology, the utility model provides a vehicle engine cylinder body grabbing device.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a vehicle engine cylinder body grasping device, comprising a cylinder, a movable positioning pin, a clamping block and a manipulator; the clamping end on one side of the manipulator is fixedly connected to the cylinder body of the cylinder, the movable end of the cylinder is fixedly connected to the movable positioning pin, the movable positioning pin is arranged facing the clamping end on the other side of the manipulator, and the clamping end on the other side of the manipulator is fixed with a clamping block.

[0006] An in-position sensor is fixed on the cylinder body of the cylinder.

[0007] A fixed positioning pin is fixed on the clamping block.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] When the utility model clamps the cylinder body, the cylinder will push the movable positioning pin to move toward the cylinder body until the movable positioning pin is completely fitted with the surface of the cylinder body, thereby achieving a close fit between the positioning pin and the cylinder body, thereby ensuring the stability of the cylinder body during clamping and positioning, enhancing the clamping force of the clamp, effectively avoiding the shaking and deviation of the cylinder body during transportation, improving the accuracy of the cylinder body position, and improving production efficiency.

[0012] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0013] A vehicle engine cylinder body grasping device comprises a cylinder 1, a movable positioning pin 3, a clamping block 4 and a manipulator 5; a clamping end on one side of the manipulator 5 is fixedly connected to the cylinder body of the horizontally arranged cylinder 1, a movable end of the cylinder 1 is fixedly connected to the movable positioning pin 3, the movable positioning pin 3 is arranged facing the clamping end on the other side of the manipulator 5, and a clamping block 4 is fixed to the clamping end on the other side of the manipulator 5.

[0014] An in-position sensor 2 is fixed on the cylinder body of the cylinder 1 .

[0015] A fixing positioning pin 6 is fixed on the clamping block 4 .

[0016] The working process of this utility model is as follows:

[0017] S1: When the manipulator 5 clamps the cylinder body, the in-position sensor 2 controls the movement of the movable end of the cylinder 1 after receiving the signal, and inserts the movable positioning pin 3 into the deep of the positioning pin hole corresponding to the cylinder body, so that the cylinder body is firmly fixed.

[0018] S2: The clamping end on the other side of the manipulator 5 is tightly attached to the cylinder body through the fixed positioning pin 6 and the contoured clamping block 4 and is deeply matched with the corresponding positioning pin hole, further ensuring the firmness of the cylinder body clamping.

[0019] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent conditions of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0020] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
