Description
Technical field
The utility model belongs to the testing tool field, especially a kind of shaft key groove symmetry detecting device.
Background technology
Shaft key groove symmetry detecting device is a kind of testing tool commonly used, in machining process, the shaft key groove position deviation occurs and can cause key to connect instability, and in the process that axle runs up, can strengthen the wearing and tearing of key, thereby influence the whole transmission of equipment, therefore, the detection to the shaft key groove symmetry is very important.The testing tool more complicated commonly used of proof bar keyway symmetry in the market, the cost height is operated loaded down with trivial detailsly, uses inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, easy to use, can accurately detect the shaft key groove symmetry detecting device of a last slotting position.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of shaft key groove symmetry detecting device is made of digital display dial gauge, arc handle, locking device, measurement mechanism, it is characterized in that:
(1). the upper end of arc handle is shaped on the adjusting slotted hole that locking device is installed, and its lower end is shaped on the adjusting circular hole of the interrupted digimatic micrometer installed;
(2). locking device is made of latch segment, locking swing handle, but radially is shaped on the rise radial direction through hole of piece of setting-in measurement mechanism at the latch segment of locking device middle part, and this piece that rises is by the locking swing handle top dress coaxial with latch segment;
(3). measurement mechanism constitutes by regulating swing handle, the piece that rises, ball, and a ball built in the made through hole of piece middle part radial position that rises is adorned on the top, end of the adjusting swing handle of wherein coaxial with the piece that rises and precession, in the lower shaft of the piece that rises of this ball position to being shaped on the seam that rises.
And described locking swing handle and adjusting swing handle all adopt screw-threaded engagement to install with the latch segment and the piece that rises respectively.
Advantage of the present utility model and beneficial effect are:
1. the digital display dial gauge of this shaft key groove symmetry detecting device is installed in the made adjusting circular hole of arc handle by lock-screw, locking device is installed in the adjusting slotted hole of arc handle upper end by lock-screw, during use, only need to detect the axle part of different-diameter by each circular hole on the arc handle and slotted hole, sensing range is bigger, and easy accessibility, weight is lighter.
2. this shaft key groove symmetry detecting device adopts digital display dial gauge, has improved the precision that detects, and adopts lock-screw to install, and can change corresponding digital display dial gauge by measuring accuracy.
3. the utility model one-piece construction is simple, and is simple to operate, and design science is reasonable, the precision height, volume is little, cost is low, in light weight, easy to use, sensing range is bigger, is a kind of shaft key groove symmetry detecting device that can accurately detect a last slotting position.

Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of shaft key groove symmetry detecting device constitutes by digital display dial gauge 12 and with the locating device of its installation, and wherein digital display dial gauge is the commercially available prod.The structure of the described locating device of present embodiment is such: main body is made of arc handle 9, locking device, measurement mechanism, wherein:
1. the upper end of arc handle is shaped on and regulates slotted hole 2, and the lower end is shaped on interrupted adjusting circular hole 11, and digital display dial gauge is installed in one of them by lock-screw 10 and regulates in the circular hole, and the adjusting slotted hole of arc handle is installed on the locking device by lock-screw 8.
2. locking device is made of the latch segment 4 of locking swing handle 3 and and employing screw-threaded engagement coaxial with this locking swing handle, be shaped on a radial direction through hole 14 at the latch segment medium position, setting-in measurement mechanism in this radial direction through hole, the locking swing handle can push up the dress measurement mechanism by the engagement precession in latch segment.
3. measurement mechanism is made of adjusting swing handle 1, the piece 7 that rises, ball 6, regulate that swing handle is coaxial to be installed in the piece that rises in the screw-threaded engagement mode, but radially be shaped on the through hole 5 of a setting-in ball at the middle part of this piece that rises, but regulate swing handle by the engagement precession jacking ball in the piece that rises, in the lower shaft of the piece that rises of this ball position to being shaped on the seam 13 that rises.
The piece that rises of setting-in measurement mechanism in the radial direction through hole of locking device.This piece that rises can be customized according to the size of disalignment keyway, change, to satisfy different needs.
The utility model principle of work:
The piece that rises on the measurement mechanism of shaft key groove symmetry detecting device is put into shaft key groove, rotate and regulate swing handle, make the lower end jacking ball of regulating swing handle, when the ball piece that will rise rises to the inwall of shaft key groove both sides, can adjust the position of the digital display dial gauge that arc handle installs this moment, when digital display dial gauge shows reading, the fixing position of arc handle and digital display dial gauge, to regulate swing handle outwards winding, unload the piece that rises, this detecting device Rotate 180 degree is continued to measure, and explanation shaft key groove symmetry is ideal when reading is consistent, and its difference is the error of symmetry.
