Abstract
Piano truckle height detecting device is fixed with two faggings that the up end is located same horizontal plane on the frame, the pick-up plate of free activity about the through-hole on the fagging can be, terminal for the toper of terminal surface under the pick-up plate, and the gauge head of installing the percentage table on the frame is contradicted with the conical surface of pick-up plate lower extreme. Three points form a plane, and the assembly error of the piano foot is checked by detecting the fourth caster. Put the fourth truckle on the pick-up plate, the height that the toper face of pick-up plate and percentage table contradict can acquire the truckle, simple structure, detect convenient, accurate, reduced manual measurement's error.
Description
Technical Field
The invention relates to a height measuring device, in particular to a piano caster height detecting device.
Background
The piano truckle directly influences the quality of piano with the height error of accurate base face, and at present in the production of piano, the piano truckle adopts artifical chock to accomplish with the altitude measurement of accurate base face mostly, because the piano quality is very big, and the manual operation error is big and inconvenient.
Disclosure of Invention
In order to overcome the defects of the prior art, the piano foot caster height detection device is provided. The detection device is reasonable in structure, simple and accurate in detection, reduces errors of manual detection, and improves labor efficiency.
In order to achieve the purpose, the invention adopts the following technical scheme:
the piano caster height detection device comprises a base, wherein two parallel supporting plates are fixed on the base, and the upper end surfaces of the two supporting plates are positioned on the same horizontal plane; one of the supporting plates is provided with a vertical through hole, a bearing seat is installed in the through hole, a detection plate is installed in the bearing seat, the upper end of the detection plate is a disc, the lower end of the detection plate is a protruding cylinder, the tail end of the lower end face of the detection plate is conical, a reset spring is sleeved between the outside of the cylinder at the lower end of the detection plate and the bearing seat, the top of the reset spring is abutted against the lower end face of the disc at the upper end of the detection plate, and the bottom; a transverse through hole is formed in the base, the dial indicator is installed on the base, and a measuring head of the dial indicator penetrates through the transverse through hole to be abutted to a conical surface at the lower end of the detection plate.
According to the piano caster height detection device, the shaft sleeve is arranged between the bearing seat and the detection plate, the shaft sleeve is fixed on the inner wall of the bearing seat, and the reset spring is arranged between the shaft sleeve and the bearing seat.
Foretell piano truckle height detecting device installs the first display screen of being connected with the percentage table outside the vertical through-hole of fagging.
The upright post is fixed on the base, and the second display screen connected with the dial indicator is arranged on the upright post.
The piano is pushed by the detection device to be detected, four trundles of the piano are sequentially placed on two parallel supporting plates, one trundle of the piano is placed on the detection plate, a plane is positioned at three points, the height of the detected trundle reflects the overall height of the piano, when the detected trundle is too high or too low, the detection plate can be vertically displaced, and the height of the detection plate can be read through the collision of the conical surface at the tail end below the detection plate and a dial indicator, so that the height of the detected trundle is known, and whether the height of the trundle of the piano is within an error allowable range is finally known, namely whether the installation size of the trundle of the piano is qualified.
The existing dial indicator has a mature electronic dial indicator and a data interface for displaying reading by an external display screen. The electronic dial indicator can be used, and is conveniently connected with a display screen to read data. Of course, the electronic dial indicator body is also provided with a basic display screen.
The height of the caster is obtained through the collision of the conical surface and the dial indicator, the structure is simple, the detection is convenient and accurate, the errors and the complexity of manual measurement are reduced, and the production efficiency is improved.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a partially enlarged sectional view of a detecting part of the present invention.
Labeled as: 1, a machine base; 2 a first display screen, 3 stand columns, 4 a second display screen, 5 a detection plate, a conical head at the lower end of the detection plate 51, a return spring 52, a shaft sleeve 53, a bearing seat 54, a second support plate 6, a first support plate 7, a caster of a piano 8, a dial indicator 9 and a measuring head of a dial indicator 91.
Detailed Description
Referring to the attached drawings, the piano caster height detection device comprises a base 1, wherein two parallel supporting plates 6 and 7 are fixed on the base, and the upper end surfaces of the two supporting plates are positioned on the same horizontal plane; the detection device comprises a first supporting plate 6, a detection plate 5, a disc, a protruding cylinder, a bearing seat 54, a shaft sleeve 53, a reset spring 52, a bearing seat, a bearing plate, a first supporting plate and a second supporting plate, wherein the first supporting plate 6 is provided with a vertical through hole, the bearing seat 54 is arranged in the through hole, the detection plate 5 is arranged in the bearing seat, the upper end of the detection plate is provided with the disc, the lower end of the detection plate is provided with the protruding cylinder, the tail end of the lower end surface is provided with a cone 51, the shaft sleeve 53 is arranged between the bearing seat and the detection plate, the shaft sleeve is fixed; a transverse through hole is formed in the base, the dial indicator 9 is installed on the base, and a measuring head 91 of the dial indicator penetrates through the transverse through hole to be abutted against a conical surface at the lower end of the detection plate; a first display screen 2 connected with a dial indicator is arranged outside the vertical through hole of the supporting plate; an upright post 3 is fixed on the base, and a second display screen 4 connected with the dial indicator is arranged on the upright post.
The contact surface of the four casters of the piano with the ground must be kept within a certain tolerance. When the piano was placed on the support frame panel, it was three truckles all the time as the reference surface, because a face is confirmed to three points to whether the fourth truckle that as long as detect the piano is higher than or is less than the reference surface can know production installation error.
Push the parallel fagging with the piano, place four truckles on the fagging, and the fourth truckle is put on the pick-up plate, and this fourth truckle that only waits to detect highly can drive the pick-up plate and slide from top to bottom along the axle sleeve, and the conical surface and the percentage table gauge head of pick-up plate lower extreme are contradicted, can show the upper and lower displacement data of this fourth truckle on the percentage table, and external display synchronous display displacement data to can judge the planar distance that this foot and other three-legged constitute.
The measuring head of the electronic dial indicator is provided with a resetting device, the detection plate descends, the conical surface can abut against the measuring head to move back, when the trundle is removed, the detection plate ascends to the initial position under the action of the reset spring, the conical surface ascends, the resetting device of the measuring head ejects out the measuring head, but the resetting device of the measuring head can abut against the conical surface to prepare for next measurement.
According to the invention, the second display is arranged on the upright post, so that the reading of a detector is facilitated, and the detector can read the display by standing; the first screen mounted on the spreader may also be used for reading and may be used as a default display.
