Abstract

The utility model relates to a detecting instrument of drop height of heavy-duty automobile front axle. The both ends of a base plate are fixed with sockets, and the upper end of each socket is provided with a slide board. The outer side of the slide board is provided with a handle, and the inner side of the slide board is fixed with a V-shaped block and a testing block; The middle part of the base plate is provided with a swinging socket, the swinging socket is fixed with a swinging block, and the swinging block is fixed with two support rods; testing boards are fixed on the sockets through a positioning block; the spacing of the top of the support rods and the top of the testing block is equal to the drop height of a tested front axle. The utility model has the advantages of convenient testing, simple operation, high testing qualification rate and can avoid the occurrence of processing waste products.

Description

A kind of pick-up unit of automobile front axle

(1) technical field

The utility model relates to a kind of verifying attachment of heavy-duty car front axle drop, belongs to forging detection technique field.

(2) background technology

At present, the detection of preceding forging shaft is to use the detection model more, is lifting model by the operator and is detecting, and its operation easier is bigger, and the workman is required height, and labour intensity is big, detects the quality instability, and rejection rate is very high always.

(3) summary of the invention

The utility model proposes a kind of novel detection device of design at having the deficiency that detects model now, and the drop that is specifically designed to front axle detects, and makes the qualified front axle drop of detection meet designing requirement fully, guarantees that front axle processing drop 100% is qualified; Process redundancy is even up and down to guarantee front axle two spindle noses simultaneously, avoids occurring the processing waste product.

The utility model is realized by following measure:

The pick-up unit of automobile front axle of the present utility model is: fix two vertical bases respectively at rectangular base plate two ends, the upper end of each base is equipped with transportable slide plate, the outside of slide plate is equipped with the handle that slide block is moved, and the inboard of slide plate is fixed with vee-block and proof mass; The middle part of base plate is equipped with two transportable swing bases, is fixed with swinging block on the swing base, is fixed with two support bars on the swinging block; Inspection panel is fixed on the base by the locating piece bearing; The spacing at the top of support bar and the top of proof mass equals the drop of detected front axle.

Utilize automobile front axle pick-up unit of the present utility model, can detect the front axle drop easily and whether linearity meets the requirements, whether process redundancy is even up and down can to detect spindle nose, and whether spindle nose is crooked, and whether the linearity of front axle meets the requirements.

The beneficial effects of the utility model are that easy to detect, simple to operate, detection qualification rate height avoids occurring the processing waste product.

Among the figure, 1,9, nut; 2,5,7,16,19, screw; 3, key; 4, swing base; 6, packing ring; 8, axle; 10, swinging block; 11, support bar; 12, inspection panel; 13 left proof mass; 14, locating piece bearing; 15, right proof mass; 17, vee-block; 18, pressing plate; 20, handle; 21, base; 22, base plate.

(5) embodiment

The structure of present embodiment as shown in Figure 1-Figure 3.Fix two vertical bases (21) respectively at rectangular base plate (22) two ends, the upper end of each base (21) is equipped with transportable slide plate, handle (20) is equipped with in both sides of slide plate, driving handle (20) can make slide block move, the proof mass (13,15) that the other end of slide plate is fixed with vee-block (17) and fixes by screw (16); The upper end of base (21) is fixing with vee-block (17) by screw (19).

The middle part of base plate (22) is equipped with two swing bases (4) that can slide by nut (1), screw (2), key (3), swing base (4) is gone up by screw (7), nut (9), axle (8) and is fixed with swinging block (10), is fixed with two support bars (11) on the swinging block (10); Inspection panel (12) is fixed on the swing base (4) by screw (5); The spacing at the top of the top of support bar (11) and proof mass (13,15) equals the drop of detected front axle.

At first, the installation and measuring device is fixed on two bases (21) on the base plate (22) earlier, makes two bases distance equal two spindle nose centre distance; Again two swing bases (4) are fixed on the base plate (22), two locating piece bearings (14) also are fixed on the swing base (4), make two locating piece bases distance equal two locating piece distances; To the drop height that requires, comprehensive check tool assembling so far finishes with the height control on the top of proof mass (15) and support bar (11) top.

The front axle testing process is:

With balance crane front axle is placed on the pick-up unit, front axle spring block locating piece is bearing on the support bar (11), promote (20) handle, make two spindle noses and V-arrangement proof mass (13) and V-arrangement proof mass (15) chucking.Whether at this moment, can detect front axle from the relative position of spindle nose, panel seat qualified.Whether axillare spring abutment and inspection panel (12) relative position can detect front axle drop and linearity and meet the requirements in the past; From the relative position of front axle spindle nose and V-arrangement proof mass (13) and V-arrangement proof mass (15), whether process redundancy is even up and down can to detect spindle nose, and whether spindle nose is crooked.

If front axle spring block and inspection panel (12) height level, then the front axle drop is qualified, if spring block and inspection panel (12) two side clearances are even, then the front axle linearity meets the requirements; If the same length that the front axle spindle nose stretches out V-arrangement proof mass (13) and V-arrangement proof mass (15), process redundancy is even up and down for spindle nose as can be known, if spindle nose is located the vee-block center substantially, then spindle nose is not crooked.

Claims

1. the pick-up unit of an automobile front axle, it is characterized in that: fix two vertical bases (21) respectively at rectangular base plate (22) two ends, the upper end of each base (21) is equipped with transportable slide plate, the outside of slide plate is equipped with the handle (20) that slide block is moved, and the inboard of slide plate is fixed with vee-block (17) and proof mass (13,15); The middle part of base plate (22) be equipped with two can be movable swing base (4), be fixed with swinging block (10) on the swing base (4), be fixed with two support bars (11) on the swinging block (10); Inspection panel (12) is fixed on the base (21) by locating piece bearing (14); The spacing at the top of the top of support bar (11) and proof mass (13,15) equals the drop of detected front axle.
