Abstract
The utility model relates to a rapid zero calibration micrometer, comprising a U-shaped meter rack, a measuring rod, a measuring anvil, a measuring rod sleeve, a measuring rod locking device and a measuring rod spinning handle; the measuring rod and the measuring anvil are coaxially arranged on two ends of the U-shaped meter rack; a middle part of the measuring rod is arranged in the measuring rod sleeve; one end of the measuring rod is connected with the measuring rod spinning handle; the measuring rod locking device is arranged on a measuring rod end of the U-shaped meter rack; and the measuring anvil is connected with the U-shaped meter rack in a screw thread mode. According to the utility model, after the measuring anvil is connected with the U-shaped meter rack in a screw thread mode, rapid zero calibration can be carried out through the mode of spinning the measuring anvil to change the relative position of the measuring anvil before measuring; thus measured value of each time can be directly read out; and zero error correction is not needed.
Description
Technical field
The utility model relates to a kind of milscale, particularly relates to a kind of quick school zero milscale.
Background technology
Milscale is claimed micrometer caliper again, is to process according to the principle that spiral amplifies, and promptly screw rod rotates a circle in nut, and screw rod just advances or the distance of a slow astern pitch along the rotation direction.The gage button position of present milscale is fixing nonadjustable, after milscale uses a period of time, and the easy zero error that occurs, its zero error directly influences the convenient of reading.If will eliminate zero error, can only adjust the relative position of screw rod and nut, comparatively complicated.
The utility model content
The utility model technical matters to be solved provides a kind of simple in structure, easy to operate quick school zero milscale.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: a kind of quick school zero milscale comprises U type chi frame, measuring staff, gage button, measuring staff sleeve, measuring staff locking device and measuring staff swing handle, wherein the coaxial two ends that are installed in U type chi frame of measuring staff and gage button; The middle part of measuring staff is as in the measuring staff sleeve; One end of measuring staff is connected with the measuring staff swing handle, and the measuring staff locking device is installed in the measuring staff end of U type chi frame, and said gage button adopts engage thread to be connected with U type chi frame.
As preferably, be provided with the gage button locking device between said gage button and the U type chi frame.
As preferably, said gage button locking device comprises lock-screw and the screw wrench that is fixedly connected with lock-screw.
As preferably, the outer end of said gage button is connected with the gage button swing handle.
As preferably, in the said gage button swing handle device for measuring force is installed.
The quick school of the utility model zero milscale; After gage button and U type chi frame adopt engage thread to be connected; Before measurement, just can change the next quick school zero of mode of gage button relative position through the rotation gage button, make each measured value directly to read, and need not revise zero error again; The quick school of the utility model zero milscale, architecture advances is simple, easy to use.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Fig. 1 is the structural representation of the quick school of the utility model zero milscale.
Wherein, Reference numeral: 1 is U type chi frame, and 2 is measuring staff, and 3 is gage button, and 4 is the measuring staff sleeve, and 5 is the measuring staff locking device, and 6 is the measuring staff swing handle, and 7 is lock-screw, and 8 is screw wrench, and 9 is the gage button swing handle.
Embodiment
Disclosed all characteristics in this instructions, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.
Disclosed arbitrary characteristic in this instructions (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
As shown in Figure 1; The quick school of the utility model zero milscale comprises U type chi frame 1, measuring staff 2, gage button 3, measuring staff sleeve 4, measuring staff locking device 5 and measuring staff swing handle 6, wherein measuring staff 2 and the gage button 3 coaxial two ends that are installed in U type chi frame 1; The middle part of measuring staff 2 is as in the measuring staff sleeve 4; One end of measuring staff 2 is connected with measuring staff swing handle 6, and measuring staff locking device 5 is installed in the measuring staff end of U type chi frame 1, and gage button 3 adopts engage thread to be connected with U type chi frame 1.
As shown in Figure 1; In zero milscale of the quick school of the utility model; Be provided with the gage button locking device between gage button 3 and the U type chi frame 1; This gage button locking device comprises lock-screw 7 and the screw wrench that is fixedly connected with lock-screw 8, just can firmly fix more through lock-screw 7 and the position of screw wrench 8 with gage button 3 behind so each school zero, avoids because of the measurement excessive gage button 3 that makes of exerting oneself relative displacements taking place.As shown in Figure 1; In zero milscale of the quick school of the utility model; The outer end of gage button 3 is connected with gage button swing handle 9; In this gage button swing handle 9 device for measuring force is installed, can adjusts the position of gage button 3 apace through gage button swing handle 9 and the device for measuring force of installing within it, and can avoid exerting oneself excessive and damage gage button 3 screw threads.
As shown in Figure 1, the quick school of the utility model zero milscale uses when carrying out the school Z-operation, opens measuring staff locking device 5 earlier, and adjustment measuring staff 2 is locked measuring staff locking device 5 again behind the zero graduation position; Open the gage button locking device then, rotation gage button swing handle 9 is fitted the gage button 3 and the end face of measuring staff 2, promptly stops operating after rotation gage button swing handle 9 is heard the kaka sound that sends in the device for measuring force, locks the gage button locking device again, promptly accomplishes quick school Z-operation.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
