CN203772172U - Cylinder-sleeve inner bore testing fixture - Google Patents

Abstract

The utility model discloses a cylinder-sleeve inner bore testing fixture which includes a base, a connection frame, telescopic poles, a dial gauge and core fixing wheel sets. The connection frame is installed on the base. All of the dial gauge and the core fixing wheel sets are installed on the connection frame through the telescopic poles. At least two core fixing wheel sets are arranged and symmetrically distributed relative to an axis of the dial gauge. Each core fixing wheel set includes at least two core fixing pulleys. The core fixing pulleys are distributed on the same linear direction and the distribution linear directions of the core fixing pulleys at the two sides of the dial gauge are mutually parallel. The cylinder-sleeve inner bore testing fixture is simple in structure, convenient to adjust, high in detection precision and easily readable in detection result; and the testing fixture is cable of ensuring detection precision and at the same time, effectively preventing damages on an inner-core surface of the cylinder sleeve so that an objective of improving the product processing quality and reducing the production cost is achieved.

Description

A kind of cylinder cover inner hole cubing

Technical field

The utility model relates to a kind of cylinder cover inner hole cubing, belongs to test measuring device apparatus field.

Background technology

At present in the production of cylinder jacket, the domestic process equipment to its endoporus mostly is multitool cylinder cover inner hole semi-finishing equipment, as two-spindle borer, cutting tool makes reamer, and in the actual processing of endoporus, due to steel jacket material, cutting output, machine tool chief axis, the reasons such as Tool in Cutting angle, very easily cause cutter or processing work to produce vibrations, thereby cause the cylinder cover inner hole processing to occur the curves such as many prismatics of One's name is legion, had a strong impact on cylinder cover inner hole crudy, and lack at present special-purpose cylinder cover inner hole testing tool, therefore the flaws such as scale error that produce with process machining at this, need to when subsequent processing, make up correction, thereby cause next procedure workload larger, and yield rate is not high, greatly reduce the production efficiency of cylinder jacket, product quality has also increased production cost, therefore in the urgent need to developing in a kind of can processing, cylinder cover inner hole is detected to special detection tool.

Summary of the invention

This novel object is just to overcome above-mentioned deficiency, and a kind of cylinder cover inner hole cubing is provided.

For achieving the above object, originally novel is to be achieved through the following technical solutions:

A kind of cylinder cover inner hole cubing is by base, link, expansion link, clock gauge and determine core wheels and form, wherein said link is arranged on base, described clock gauge and determine core wheels and be all arranged on link by expansion link, wherein determine core wheels at least two groups, and symmetrical with clock gauge axis, each is determined core wheels and determines core pulley formation by least two, the described core pulley of determining is distributed in same rectilinear direction, and the core pulley distribution rectilinear direction of determining of clock gauge both sides is parallel to each other.

The utility model have simple in structure, easy to adjust, the high and testing result of accuracy of detection easily reads, and can when guaranteeing accuracy of detection, effectively avoid cylinder sleeve bore surface to cause damage, thereby reach raising product processing quality, the object reducing production costs.

Accompanying drawing explanation

Fig. 1 is this new structure schematic diagram.

Embodiment

A kind of cylinder cover inner hole cubing is by base 1, link 2, expansion link 3, clock gauge 4 and determine core wheels and form as shown in Figure 1, wherein said link 2 is arranged on base 1, described clock gauge 4 and determine core wheels and be all arranged on link 2 by expansion link 3, wherein determine core wheels at least two groups, and symmetrical with clock gauge 4 axis, each is determined core wheels and determines core pulley 5 formations by least two, the described core pulley 5 of determining is distributed in same rectilinear direction, and the core pulley 5 distribution rectilinear directions of determining of clock gauge 4 both sides are parallel to each other.

While using it to detect workpiece, first according to tested inner hole of workpiece diameter, calculate expansion link and determine core wheels contact chord length, when determining core pulley and clock gauge pointer and contact endoporus sidewall, the center line of clock gauge overlaps with inner hole of workpiece center line, and rotational workpieces then, if when bore area size exists obvious errors or skewness, clock gauge can rule swing, thereby can judge that whether inner hole of workpiece is qualified according to the amplitude of fluctuation of clock gauge, frequency.
