Abstract
The utility model belongs to the technical field of measuring apparatuses and specially relates to a milling cutter radius measurer. The milling cutter radius measurer comprises a main ruler and a vernier. The vernier is sleeved on the main ruler and can be moved horizontally relative to the main ruler. The main ruler and the vernier are both equipped with scales. A threaded hole is disposed on the center of the top side of the vernier. A positioning screw is installed in the threaded hole. The inner end of the positioning screw is abutted against the main ruler. The top part on the left side of the main ruler is a cylinder. A positioning hole in cooperation with the lower part of a milling cutter installing shaft is disposed on the top end face of the cylinder. The milling cutter radius measurer is a product improved on the basis of a vernier caliper and is capable of accurately measuring the radius of a required cutter rod, measuring the length of the rod of the milling cutter in a processing process at any time, and preventing a phenomenon that an operator does not discover subtle change generated on the length of the cutter rod timely so as to result in unqualified processed parts.
Description
Technical field
The utility model belongs to the measurement mechanism technical field, refers in particular to a kind of milling cutter radius measurer.
Background technology
Need to mill in the manufacturing procedure of mesopore at slip cap, the size of the mesopore of the part that processes is the rear procedure of impact directly---and rounding processing, simultaneously, the size of mesopore also can affect the problem of follow-up assembling.Therefore, it is very important can processing the workpiece that more meets requirement on machining accuracy.
As shown in Figure 1, need to measure accurately the value of L, therefore can not directly measure the distance of L due to common vernier caliper, in actual mechanical process, the master worker often adjusts to meet the dimensional accuracy of processing according to oneself working experience for many years to the length of knife bar.Yet this method is for there being the master worker who enriches working experience perhaps not need the expensive working time, but may not skillfully grasp this method for the beginner, therefore these people may spend the long time and adjust the length of knife bar in practical work process, can have a strong impact on like this production efficiency of enterprise.
Summary of the invention
The purpose of this utility model is to provide a kind of structure improved milling cutter radius measurer, can measure accurately the radius of required knife bar, and can the length to cutter bar of milling cutter at any time measure in process, after slight change appears in the length that prevents knife bar, because could not in time finding, the operator causes the underproof phenomenon of the part that processes.
For achieving the above object, the utility model provides following technical scheme:
The milling cutter radius measurer, comprise main scale and vernier, vernier is set on main scale and main scale transverse shifting relatively, be provided with scale on main scale and vernier, the middle part of vernier upside is provided with threaded hole, and set screw is installed in threaded hole, and the inner of set screw is against on main scale, the top in described main scale left side is right cylinder, and cylindrical upper surface is provided with the pilot hole that coordinates with the bottom of milling cutter installation shaft.
Preferably, described pilot hole is up big and down small round platform hole.
Preferably, the circular diameter of the upper surface in described round platform hole is greater than the diameter of axle of milling cutter installation shaft, and the garden diameter of the lower surface in round platform hole is less than the diameter of axle of milling cutter installation shaft.
The utility model beneficial effect compared to existing technology is:
The utility model carries out the part improvement on the basis of vernier caliper, can measure accurately the radius of required knife bar, and can the length to cutter bar of milling cutter at any time measure in process, after slight change appears in the length that prevents knife bar, because could not in time finding, the operator causes the underproof phenomenon of the part that processes; Simultaneously, there will be the wearing and tearing of cutter due to milling cutter in process, use this measurement mechanism also can carry out corresponding cutter radius compensation to knife bar timely, to guarantee the dimensional accuracy of its processing.
Description of drawings
Fig. 1 is the schematic diagram of milling cutter.
Fig. 2 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 2, the milling cutter radius measurer, comprise main scale and vernier, vernier is set on main scale and main scale transverse shifting relatively, is provided with scale on main scale and vernier, and the middle part of vernier upside is provided with threaded hole, set screw is installed in threaded hole, the inner of set screw is against on main scale, and the top in described main scale left side is right cylinder, and cylindrical upper surface is provided with the pilot hole that coordinates with the bottom of milling cutter installation shaft.
Preferably, described pilot hole is up big and down small round platform hole.
Preferably, the circular diameter of the upper surface in described round platform hole is greater than the diameter of axle of milling cutter installation shaft, and the garden diameter of the lower surface in round platform hole is less than the diameter of axle of milling cutter installation shaft.
Pilot hole of the present utility model can stretch into for the milling cutter installation shaft, when the outer wall of milling cutter installation shaft and the laminating of the wall of pilot hole, both central axis alignment, then vernier slides, make the end joint of itself and cutter bar of milling cutter, and contact is tight as much as possible, in order to can reduce the error in measuring process.At this moment, a certain scale on scale mark on vernier can align with a certain scale on main scale, at this moment the lattice number that overlaps multiply by minimum division value and is reading on vernier, read whole millimeter take the zero graduation line on vernier as benchmark with it at main scale again, the whole millimeter that reads finally and the reading sum on vernier are the numerical value of this time measuring, the aperture that the milling cutter that can record comparatively accurately processes.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
