The utility model has high accurate detection results, easy operation, and high working efficiency.

Description

The revolving body workpieces static balance testing device

One, technical field:

The utility model relates to a kind of workpiece balance detecting device, especially a kind of revolving body workpieces static balance testing device.

Two, background technology:

Just can install and use after will reaching static equilibrium as the revolving body workpieces of emery wheel and so on, to reduce the vibrations in its work, improve security and machining precision, it is exactly to utilize static balance testing device to detect its static equilibrium state that static equilibrium detects, and makes it reach the state of indifferent equilibrium by the method for regulating the position of three counterbalance weights on the grinding wheel flange dish.Present detection method is tested revolving body workpieces to be worn with an axle roll on a balancing stand, and this method requires height to the levelness of balancing stand, and inefficiency, and the testing result accuracy is not high yet.

Three, summary of the invention:

The purpose of this utility model provides a kind of revolving body workpieces static balance testing device, and it is not high to solve the accuracy of traditional revolving body workpieces static balance testing device testing result, ineffective technical matters.

Concrete technical scheme of the present utility model is: a kind of revolving body workpieces static balance testing device, it is characterized in that: the top of the cone laser pointer that has been threaded, cone matches with the workpiece rotating central hole, one cone-shaped groove is arranged at the bottom of laser pointer, support bar top stretch in the cone and the top cone-shaped groove center bottom laser pointer of its circular cone relative up and down, the support bar bottom is fixed on the horizontal base, outside at it is set with lifting nut, surface bearing, bearing seat and carriage, carriage links to each other with surface bearing below cone and by bearing seat, and lifting nut is threaded below surface bearing and with support bar.

In the utility model revolving body workpieces by cone and laser pointer bottom cone-shaped groove be supported on the circular cone of support bar top on, and support bar is vertically fixed on the horizontal base, thereby can whether vertically judge the static equilibrium state of revolving body workpieces by observing Laser Measurement pointer light, and can come shears by lifting nut, thereby rotate revolving body workpieces by carriage, be used for detecting and adjusting the static equilibrium of revolving body workpieces, make revolving body workpieces finally reach the state of indifferent equilibrium at whole turning course.

The utility model has the advantages that: testing result accuracy height, convenient to operation, high efficiency.

Four, description of drawings:

Fig. 1 is a structural representation of the present utility model, and the revolving body workpieces assembly is partly represented in double dot dash line.

Five, embodiment:

As shown in Figure 1: the utility model is mainly by lifting nut 1, surface bearing 2, bearing seat 3, carriage 4, support bar 6, cone 7 and laser pointer 10 are formed, its architectural feature is: the top of cone 7 laser pointer 10 that has been threaded, cone 7 matches with the workpiece rotating central hole, one cone-shaped groove is arranged at the bottom of laser pointer 10, support bar 6 tops stretch in the cone 7 and the top cone-shaped groove center of its circular cone with laser pointer 10 bottoms relative up and down, support bar 6 bottoms are fixed on the horizontal base, be set with lifting nut 1 in its outside, surface bearing 2, bearing seat 3 and carriage 4, carriage 4 links to each other with surface bearing 2 below cone 7 and by bearing seat 3, and lifting nut 1 is threaded below surface bearing 2 and with support bar 6.

As can be seen from Figure 1: the below of laser pointer 10 is provided with pieces together cap 8, pieces together cap 8 and is threaded with cone 8.Carriage 4 is fixed on the bearing seat 3 by collar 5.

Principle of work: as can be seen from Figure 1: during work, 4～6 meters tilt to place a reflective mirror 12 above laser pointer 10, and target 13 is placed on a side of horizontal base, is used to receive the laser that is reflected by reflective mirror 12.Measured workpiece is placed on the carriage 4, rotation and lifting nut 1 slowly descends carriage 4 and whole workpiece, allow the cone-shaped groove center and top contact of support bar 6 upper cone of laser pointer 10 bottoms, continue rotation decline lifting nut 1, carriage 4 is separated with workpiece, the light of laser pointer 10 returns on the target 13 by reflective mirror 12, and mobile target 13 makes the target center of target 13 overlap with laser spots.Regulate lifting nut 1 once more, carriage 4 and workpiece are risen, at this moment pass through rotary bracket 4 with 180 ° of Workpiece Rotating, workpiece again descends, if workpiece imbalance, laser spots will depart from target center, regulates the counterbalance weight of workpiece, or removes unbalance part, again detect again, so repeatedly, can both aim at target center at every turn, represent that then workpiece has reached the state of static equilibrium (indifferent equilibrium) up to laser spots.
