Problems solved by technology

But another problem is: when the engine directly uses the cylinder to lift the tile cover on the pallet of the assembly line, sometimes the engine block will be lifted up as a whole, and it will be separated from the positioning pin of the pallet, which will affect the subsequent assembly. Sleeve pressing mechanism, although the problem has been solved, because the increase of the mechanism increases the overall weight of the moving parts, resulting in increased equipment energy consumption, increased equipment cost, and it is inconvenient for workers to take the tile cover

Embodiment 1

[0031] The expansion cylinder 5 is fixedly installed on the expansion cylinder seat 12, and the expansion pressure rod 7 and the expansion cylinder base 12 are locked and fixed together by the pressure rod locking block 13. The connection and fixation strength of the expanding pressure rod 7 is improved.

Embodiment 2

[0033] A down-going protective cover 14 is clamped between the return spring 8 of the expanding pressure rod 7 and the unscrewing slide table 1, and the top of the down-going protective cover 14 is retracted into a boss shape. The bottom is equipped with an upward limit block 15. The design of this place limits the longitudinal movement range of the expansion pressure rod 7, and is responsible for locating the original position and the expansion state of the expansion mechanism, which improves the reliability during operation.

Embodiment 3

[0035] The translation cylinder 9 is fixedly connected with the unscrewing slide table 1 through a translation cylinder base 16 , and a floating joint 17 is installed at the end of its piston rod, and the floating joint 17 is connected in the horizontal slide plate 4 . The design at this place can effectively improve the service life of the translation cylinder during operation.

Abstract

The invention discloses an automatic opening mechanism for an automobile engine tile cover. The automatic opening mechanism comprises an unscrewing sliding table. Sliding blocks are symmetrically arranged on two sides of the bottom of the unscrewing sliding table along the length direction, guide rails matched with the sliding blocks are arranged below the sliding blocks, and the bottoms of the guide rails are fixed on a horizontal sliding plate. An opening cylinder is arranged on the upper portion of the unscrewing sliding table, the extending-out end of a piston rod of the opening cylinder is connected to an opening pull rod, an opening pressure rod parallel to the opening pull rod is fixedly installed on the side edge of the bottom of the opening cylinder, the opening pull rod and the opening pressure rod sequentially penetrate through the unscrewing sliding table and the horizontal sliding plate, a returning spring is further sleeved on an outer wall of the opening pressure rod adjacent to the unscrewing sliding table, a translation cylinder pushing the horizontal sliding plate to move along the direction of the sliding blocks is arranged outside the horizontal sliding plate positioned on the side of the opening pressure rod, and an opening top block and an opening pressure block are respectively installed at the bottom end of the opening pull rod and the bottom end of the opening pressure rod. The automatic opening mechanism is simple in structure and convenient to use, and stability and reliability of the opening process of the tile cover in assembly can be effectively guaranteed.

Description

[0001] technical field [0002] The invention relates to the technical field of automobile engine manufacturing, in particular to an automatic tile cover expansion and opening mechanism applied on an automobile engine assembly line. [0003] Background technique [0004] As the driving system of the car, the engine is the source of all the power of the car and an extremely important part of the car. The inner hole composed of the tile cover and the cylinder block used to fix the crankshaft in the automobile engine is processed together and needs to be matched, and cannot be replaced casually. The processing method in the prior art is: mark the tile cover after processing, loosen and disassemble it with tools, and transport it to the assembly workshop for assembly. However, when the number of engine cylinders is relatively large, confusion still inevitably occurs . In order to avoid this situation, the engine factory changed the unscrewing and expanding process to the asse...
