Abstract
A device for testing welding strength of an oil nozzle comprises a base, wherein a working table and a testing slide which are capable of sliding relative to the base are arranged on the base, a propelling hydraulic cylinder is installed at the front end of the testing slide on the base, and a pressing hydraulic cylinder parallel to the propelling hydraulic cylinder is fixed on the working table. On the working table, two boosting slides are arranged at the front end of the pressing hydraulic cylinder, a boosting hydraulic cylinder provided with the oil nozzle through welding is placed between the two boosting slides, a sensor is fixedly installed at the front end of the working table on the base, and a pressure meter is externally connected onto the pressure sensor; the sensor is fixedly installed on a fixing block welded on the base; and the testing slide is connected with the working table through sliding grooves, the working table is connected with the base through sliding grooves, and the two boosting slides are connected onto the working table through sliding grooves. The device for testing welding strength of the oil nozzle is simple in structure, low in cost, convenient to operate, high in testing efficiency and accuracy, strong in university and low in production cost.
Description
Technical field
The utility model relates to a kind of device that is used to check the oil nozzle weld strength.
Background technology
Hydraulic power-assisted steering is the highest a kind of servo steering system of current popularity rate, generally is made up of steering control valve, steering actuation cylinder and steering pump, steering reservoir etc.As the important component part in the hydraulic power-assist steering system, servo-cylinder plays and promotes the effect that piston rod turns to, and oil nozzle is very important assembly as the coupling part of cylinder body oil-feed and oil return.If oil nozzle and cylinder body weld strength are not high, possibly cause oil nozzle and cylinder body to come off under the extreme operating condition, directly cause steering to lose efficacy.Lack a kind of device that can check the weld strength of oil nozzle very easily in the prior art.At present generally adopt cupping machine to carry out the check of oil nozzle weld strength, need to make special-purpose test frock, and troublesome poeration, the test period is long, so efficient is low, and cost is high.
The utility model content
The purpose of the utility model is to propose a kind of device that is used to check the oil nozzle weld strength, has solved oil nozzle weld strength check difficulty, and cost is high, the problem that checkability is low.
For reaching this purpose, the utility model adopts following technical scheme:
A kind of device that is used to check the oil nozzle weld strength; Comprise base; The worktable and check slide block of base slip relatively are installed on the said base, and the check slip front is installed with the PF cylinder pressure on the said base, is fixed with one side by side with the PF cylinder pressure on the worktable and compresses hydraulic cylinder; Compress the hydraulic cylinder front end on the said worktable two power-assisted slide blocks are arranged; Be placed with the booster cylinder that is welded with oil nozzle in the middle of said two power-assisted slide blocks, said base upper table front end is installed with pressure transducer, and said pressure transducer is circumscribed with tensimeter.
As a preferred version, said sensor is fixedly mounted on the fixed block that is welded on the base.
As further preferred version, chute is connected between said check slide block and the worktable, and chute is connected between said worktable and the base, and said two power-assisted slide block chutes are connected on the worktable.
The utility model is simple in structure, and is with low cost, and easy to operate; Detection efficiency and accuracy are all higher, and operating personnel only need be placed on servo-cylinder can begin operation, highly versatile between two power-assisted slide blocks on the worktable; Need not make special-purpose test frock, reduce production cost.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the utility model one-piece construction synoptic diagram.
Among the figure:
1, base; 2, sensor; 3, worktable; 4, booster cylinder; 5, oil nozzle; 6, check slide block; 7, compress hydraulic cylinder; 8, PF cylinder pressure; 9, tensimeter; 10, power-assisted slide block; 11, fixed block.
Embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and through embodiment.
Fig. 1 is the apparatus structure synoptic diagram that is used to check the oil nozzle weld strength that the utility model embodiment provides; The worktable 3 and check slide block 6 of base 1 slip relatively are installed on the base 1 among the figure; Chute is connected between check slide block 6 and the worktable 3, and chute is connected between worktable 3 and the base 1, checks the front end of slide block 6 on the base 1; Fixing PF cylinder pressure 8; Be fixed with one side by side with PF cylinder pressure 8 on the worktable 3 and compress hydraulic cylinder 7, compress on the hydraulic cylinder front end stage and be connected and installed with 10, two power-assisted slide blocks of two power-assisted slide blocks, the 10 middle booster cylinders 4 that are welded with oil nozzle 5 of placing through chute; On the fixed block 11 of said base 1 upper table 3 front ends sensor 2 is installed, said sensor 2 is circumscribed with tensimeter 9.
The utility model is simple in structure; With low cost, and easy to operate, and detection efficiency and accuracy are all higher; Operating personnel only need be placed on booster cylinder 4 can begin operation between two power-assisted slide blocks 10 on the worktable 3; Highly versatile need not made special-purpose test frock, has reduced production cost.
Claims (3)
1. device that is used to check the oil nozzle weld strength; It is characterized in that, comprise base, the worktable and check slide block of base slip relatively is installed on the said base; The check slip front is installed with the PF cylinder pressure on the said base; Be fixed with one side by side with the PF cylinder pressure on the worktable and compress hydraulic cylinder, compressing the hydraulic cylinder front end on the said worktable has two power-assisted slide blocks, is placed with the booster cylinder that is welded with oil nozzle in the middle of said two power-assisted slide blocks; Said base upper table front end is installed with pressure transducer, and said pressure transducer is circumscribed with tensimeter.
