Embodiment Construction
[0027] The following is a specific embodiment of the present invention, the present invention is further described in conjunction with the accompanying drawings.
[0028] combine Figures 1 through 3 As shown, a flip position lifting load-bearing cylinder test device, the base 1 is arranged horizontally, the base 1 is connected to the flip frame that can be flipped, and the mounting plate 19 has an adjustable angle on the flip frame. The flip frame is mounted with a lifting carrier frame that can be lifted or lowered relative to the flip frame.
[0029] The flip frame includes a flip frame body 4, the base 1 is fixed with the flip ear plate 3, and the right end of the flip rack body 4 is hinged to the flip ear plate 3. The reaming between the middle of the flip frame body 4 and the base 1 is conjugated with a displacement jacking cylinder 2, and the flip angle of the flipping frame body 4 is controlled by the telescopic expansion of the displacement jack thrust cylinder 2.

The invention discloses a turnover displacement lifting bearing type oil cylinder testing device, and belongs to the technical field of hydraulic cylinders. The base is connected with an overturning rack, and the overturning rack is provided with a lifting bearing rack; a mounting bottom plate is hinged to the overturning rack body, and an angle adjusting screw lifter is arranged on the lower side of the mounting bottom plate. Four lifting guide columns arranged in a rectangular mode are fixed to the overturning rack body, and the lifting bearing rack body is in sliding fit with the lifting guide columns. Lifting adjusting screw lifters are arranged on the lower sides of the two ends of the lifting bearing rack body correspondingly. A through groove is formed in the lifting bearing rack body, a tool connecting base is fixed to one end of the through groove, and a stroke pushing oil cylinder is fixed to the other end of the through groove. According to the invention, the test requirements of reciprocating stroke, neutral-position pressure resistance, vertical smoothness and the like of the tested plunger oil cylinder are met, the overall structure of the device is compact, the adjustment function is convenient, the device is suitable for tests of plunger oil cylinders of various types and specifications, and the universality and the comprehensive efficiency of the device are better.
Description
Technical field [0001] The present invention relates to the technical field of hydraulic cylinders, specifically a kind of flip position lifting load bearing cylinder test device. Background [0002] Plunger cylinder products need to be tested on reciprocating stroke, median pressure resistance, vertical smoothness and other items before leaving the factory. In the existing technology, the test bench of the plunger cylinder is integrally fixed, the installation of the test cylinder adopts the fixed bracket support, and the stroke reciprocating of the plunger cylinder is dragged by the cylinder or power chain, and the test function is single. [0003] The shortcomings of the prior art are: [0004] 1. The fixed test bench is difficult to adapt to a variety of types and different lengths, diameters and specifications of the plunger cylinder, and does not have the universality of installation angle adjustment and connection; [0005] 2. It does not have the bearing function of the m...
