Embodiment 1

[0040] like figure 1 As shown, the clamping method of the hanger for clamping the finished cylinder head provided by the embodiment of the present invention includes:

[0041] S101, which meets the general requirements of 2.0L / 2.5L cylinder head finished products, and selects the same shape and structure as the clamping point: the rough surface of the outer wall of the main oil passage.

[0042] S102, hold the pull rod 1, tighten the jaw body 2, and extend into the lower part of the workpiece.

[0043] S103 , release the pull rod 1, and release the gripper body 2, so that the workpiece can be clamped.

[0044] In the embodiment of the present invention, after the jaw body 2 is released, it is always under the action of its own weight, and through the structure of the blunt hook structure 9, the outer wall of the main oil passage is just embedded in the groove of the curved portion of the blunt hook structure 9, At this time, the electric hoist can lift up the workpiece (simi...

Embodiment 2

[0046] Use the clamping method of the hanger for clamping the finished cylinder head provided in Example 1, such as Figure 2-Figure 4 As shown, the hanger for clamping the finished cylinder head provided by the embodiment of the present invention includes: a tie rod 1 , a clamping jaw body 2 , a clamping jaw slideway 3 , a clamping jaw intermediate connecting part 4 , and a clamping body 5 .

[0047] The clamping body 5 is provided with a clamping jaw slideway 3; the sliding cavity of the clamping jaw slideway 3 is interspersed with a pull rod 1;

[0048] The tie rod 1 is fixed with a clamping claw intermediate connecting portion 4 through bolts; the clamping claw intermediate connecting portion 4 is connected to the clamping claw body 2 through bolts.

[0049] In a preferred embodiment of the present invention, the lower part of the middle connecting part 4 of the clamping jaw is connected to the bending node part of the clamping jaw body 2 through the rotating shaft 8;

Abstract

The invention belongs to the technical field of clamping machinery, and discloses a lifting appliance for clamping a cylinder cover finished product and a clamping method. The lifting appliance for clamping the cylinder cover finished product comprises a clamping body, and a clamping jaw sliding way is formed in the clamping body; a pull rod is inserted into a sliding cavity of the clamping jaw sliding way in a penetrating mode. A clamping jaw middle connecting part is fixed on the pull rod through a bolt; the clamping jaw middle connecting part is connected with the clamping jaw body through a bolt; the clamping jaw body is connected with an auxiliary clamping jaw structure through a rotating shaft. The lifting appliance can be universally used for TNGA 2.0 L / 2.5 L cylinder cover finished products, and lifting appliance replacement operation during mixed flow production is avoided. Operation can be conducted with one hand, the hand action range is small, and use is easy, easy and convenient. And the clamping contact part is a blank surface, so that the workpiece is prevented from being scratched. The universal lifting appliance is changed from nothing to one, and safety guarantee is provided for field operators to carry out encasement and warehouse pouring operation.

Description

technical field [0001] The invention belongs to the technical field of clamping machinery, and in particular relates to a hanger for clamping finished cylinder head products and a clamping method. Background technique [0002] In the prior art, the production of TNGA 5# cylinder head line will start in July 2021, and it will be mass-produced in November, producing 2.0L / 2.5L workpieces. The finished product involves the packing and warehouse-reversing operations of the two types of workpieces, which are of high frequency and high intensity (heavy object operations), and cannot be directly transported by manpower. A single-arm crane and an electric hoist are equipped for heavy work, but there is no sling that can hold the finished 2.0L / 2.5L cylinder head. There is only one set of single-arm crane and electric hoist, but the operation involves mixed-flow operation of 2.0L / 2.5L cylinder head and workpiece. In order to avoid the waste of man-hours caused by the replacement of th...
