Abstract
The invention discloses a measuring device for a mesh clearance value of a gear rack of a steering engine. The measuring device comprises a caliper structure and a dial indicator, wherein a jaw of the caliper structure comprises two arc-shaped fixture blocks respectively connected to two caliper body arms of the caliper structure, the inner walls of the arc-shaped fixture blocks are matched with the shape of the outer surface of a shell of the steering engine, and the dial indicator is connected to the caliper structure through a locking block. By adopting the structure and the method, the measuring device has the following advantages that 1, measurement is accurate, and the tool replacement efficiency and the yield are improved; 2, the inner walls of the arc-shaped fixture blocks are matched with the shape of the outer surface of the shell of the steering engine, so that the shell of the steering engine can be clamped by the caliper structure; 3, a tooth-shaped structure is arranged on the surface of the inner wall of each arc-shaped fixture block, so that the friction can be increased and clamping is firmer.
Description
Technical field
The present invention relates to steering box technical field, particularly a kind of steering box rack meshing clearance value measurement mechanism.
Background technology
At present, the measurement of steering box rack meshing clearance value is directly measured by dial gauge, but dial gauge self instability when measuring is large, easily causes measurement data inaccurate, reduces the efficiency that frock is changed, and reduces production capacity.
Summary of the invention
Technical matters to be solved by this invention is, for the deficiencies in the prior art, provides a kind of and measures accurate, to improve frock replacing efficiency and production capacity steering box rack meshing clearance value measurement mechanism.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of steering box rack meshing clearance value measurement mechanism, comprise clamp structure, dial gauge, the jaw of described clamp structure comprises two arc fixture blocks be connected with two caliper arms of clamp structure respectively, described arc fixture block inwall and steering box housing outer surface matching form close, and described dial gauge is connected in clamp structure by latch segment.
When described clamp structural clamp is under steering box housing state, the measuring head of described dial gauge contacts with the tooth bar in steering box housing, and the axle center of tooth bar is placed on the measuring head extended line of dial gauge.
Described latch segment is provided with contiguous block, clamp, and described clamp is provided with the through hole supplying the measurement headstock of dial gauge to pass, and described clamp is by bolt-locking, and described contiguous block is welded in described clamp structure.
The caliper arm of described clamp structure is provided with setting nut.
The present invention adopts said structure, has the following advantages: 1, measure accurately, improve frock replacing efficiency and production capacity; 2, arc fixture block inwall and steering box housing outer surface matching form close, and make clamp structure can clamp steering box housing; 3, the measuring head of dial gauge contacts with the tooth bar in steering box housing, and the axle center of tooth bar is placed on the measuring head extended line of dial gauge, under the state that ensure that clamp structure clamping steering box housing, the measuring head of dial gauge is perpendicular to the steering box surface of shell tangent line be in contact with it, and the situation effectively preventing the instability due to dial gauge self from causing measuring false gap occurs.
