Abstract
The utility model relates to a parallel light projection caliper. A parallel light emitting unit and a receiving unit are oppositely arranged, a clamping device is arranged at a measuring zone between the parallel light emitting unit and the receiving unit without obstructing the outside of an optical path of a parallel light beam emitted by the emitting unit, thereby causing a measured object to be perpendicular to the beam, and the parallel light emitting unit is connected with a computer processor. The parallel light projection caliper has the advantages that firstly, measurements of an outside diameter size of a total cross-section, as well as average diameter, maximum diameter, minimum diameter and non-circularity of the cross-section of the measured object can be automatically completed; secondly, for being provided with a movable road wheel, the whole caliper is convenient to move.
Description
Technical field
The utility model belongs to a kind of noncontact outside diameter measuring device, relate in particular to a kind of measurement that can realize the outside dimension of the whole cross section of measured object all directions automatically, and calculate a kind of caliper of external diameter mean value, maximal value, minimum value and the out-of-roundness etc. of measured section.
Background technology
Present known caliper based on the photoelectricity projection theory only can be from a direction or plurality of fixed direction projection Measuring Object external diameter, as utility model patent ZL00238166.4, and the cross dimensions measurement mechanism of high-speed moving object.For the outside dimension of Measuring Object complete cross-section, what have rotates caliper around measured object, as the caliper of Britain IPL company; The swing that has as the caliper of Switzerland ZUMBACH company, realizes the projection measurement of total cross-section.This mode with caliper swing or wheel measuring external diameter projection size, complicated in mechanical structure, heaviness, inconvenience is moved, and influences measuring accuracy.
The utility model content
The purpose of this utility model is to overcome the above-mentioned technological deficiency that is used to measure the complete cross-section outside dimension at present, a kind of caliper is provided, and it can finish the measurement of mean diameter, maximum gauge, minimum diameter and the out-of-roundness in the outside dimension of measured object total cross-section and this cross section automatically.
The technical solution of the utility model is: a kind of caliper, it is characterized in that: it comprises directional light transmitter unit, directional light receiving element and clamping device, described directional light transmitter unit and receiving element are oppositely arranged, the measurement zone of clamping device between directional light transmitter unit and receiving element, do not block the outside that transmitter unit sends the light path of parallel beam, make measured object perpendicular to light beam, the directional light receiving element connects computing machine.
Described clamping device, it comprises gripper jaw, locking plate, motor and transmission gear for electric motor, and transmission gear for electric motor is connected the rotating shaft of motor with gripper jaw, and locking plate is sleeved on the gripper jaw outside, is used for fastening and unclamps gripper jaw.
Described directional light transmitter unit is the narrow-band LED light source.
Described directional light receiving element is the high speed linear array CCD video camera.
Described caliper is equipped with road wheel.
The beneficial effects of the utility model are:
(1) outside realizing the function of general caliper, can finish the measurement of mean diameter, maximum gauge, minimum diameter and the out-of-roundness in the outside dimension of measured object total cross-section and this cross section automatically.
(2) because whole caliper is equipped with road wheel, complete machine moves very convenient.
