Description

Roller dynamic balance testing device

Technical field

The utility model relates to dynamic balancing testing equipment field, in particular to a kind of roller dynamic balance testing device.

Background technique

Currently, printing machinery develops to high speed, full-automatic production line direction.Large high-speed roller is high print duplication Mechanical important spare part is brushed, is contacted by the die plate being mounted on high speed roller with printed paperboard, by the shape of stamp version Ink is stamped in printed paperboard surface, to print various patterns.The height of roller surface finish, geometric accuracy The quality of printed matter can be had an important influence on.

Roller needs to carry out constantly high speed rotation in actual use, in rotary course, since roller is relative to axis The non-uniform mass of line and centrifugal force can be generated.This imbalance centrifugal force, which acts on, can cause to vibrate on roller bearing, It generates noise and accelerates bearing wear, can also seriously affect the quality of printed matter.Therefore, roller in the process of production and processing must Dynamically balanced test must be carried out to it.The amount of unbalance for the data pair roller barrel measured according to balancing machine is corrected, and can improve roller Mass Distribution of the cylinder relative to axis, the vibration generated when rotating roller or the vibration force acted on bearing are reduced to permission Within the scope of.

Utility model content

The utility model is intended to provide a kind of roller dynamic balance testing device, can compress roller and carry out dynamic balancing measurement, To improve test result accuracy rate.

In order to solve the above technical problems, base case provided by the utility model is as follows:

Roller dynamic balance testing device, including bottom plate are set on bottom plate there are two opposite first support and second support, the It respectively being opened up on one bracket and second support there are two through-hole, through-hole is interior to be equipped with support shaft, it is rotatably connected to support wheel in support shaft, Support wheel in the first support and second support is oppositely arranged；The bottom plate is equipped with connection close to the side of first support Plate, connecting plate are equipped with the third bracket for placing dynamic balance measuring instrument, and third bracket includes vertical part and the horizontal part, third Sliding panel is slidably connected on the vertical portion of bracket, and the circular hole of installation motor is offered on the upside of sliding panel, is opened on the downside of sliding panel Equipped with the first strip-shaped hole, the first threaded hole that can be overlapped with the first strip-shaped hole is offered on the vertical portion of the third bracket, the It is fixedly connected by passing through the first strip-shaped hole with the bolt that the first threaded hole cooperates between three brackets and sliding panel；Described second Frame is equipped with pinch roller frame, and the sliding rack perpendicular to bottom plate is slidably connected on pinch roller frame, and the lower rotation of sliding rack is connected with pressure It takes turns, offers the second strip-shaped hole on sliding rack, the second threaded hole is offered on pinch roller frame, by wearing between pinch roller frame and sliding rack It crosses the second strip-shaped hole and is fixedly connected with the bolt that the second threaded hole cooperates.

The working principle of base case: roller being placed on the support wheel of first support and second support, adjusts sliding The height of plate, the main shaft of the output shaft and roller that make motor is on same straight line, after sliding Board position adjustment, by spiral shell Bolt passes through the first strip-shaped hole of sliding panel and the first threaded hole of third bracket cooperates, and tightens bolt for sliding panel and is fixed on third On bracket, then the main shaft of roller is connected on the output shaft of motor, it is sliding on pinch roller frame since second support is equipped with pinch roller frame The dynamic sliding rack being connected with perpendicular to bottom plate, the lower rotation of sliding rack are connected with pinch roller, adjust the height of sliding rack, make pulley The pinch roller of frame bottom is contacted with roller, then bolt is passed through the second strip-shaped hole on sliding rack and the second threaded hole on pinch roller frame Cooperation, bolt is tightened so that sliding rack is secured firmly on pinch roller frame, so that pinch roller is by roller close to the side of second support Press on two support wheels on the secondary support bracket, and roller is also pressed on by motor output shaft close to the side of first support On two support wheels on one bracket, and then realizes and compress whole roller.

Start motor, under the drive of motor output shaft, roller is started turning, during roller rotation, roller meeting Entire bottom plate, first support, second support and third mount vibration are driven, the dynamic balance measuring instrument on third bracket can be to vibration Direction and amplitude measure, to realize the dynamically balanced detection of pair roller barrel by dynamic balance measuring instrument.

Base case has the beneficial effect that

1, compared with existing roller dynamic balance detector, the utility model by two support wheels in first support and The output shaft of motor realizes that compression of the pair roller barrel close to first support side is firm, by two support wheels in second support and Adjustable pinch roller realizes that compression of the pair roller barrel close to second support side is firm, allows whole roller during rotation can be by It securely compresses, extraneous factor is avoided to influence the dynamic balancing measurement result of roller itself.

2, sliding panel and the adjustable height of sliding rack, carry out dynamic balancing to roller of different specifications and sizes to can realize Test.

Further, the bottom plate offers multiple jacks close to the side of second support, and jack is set along floor length direction It sets, the second support includes vertical plate and level board, offer multiple strip grooves on the second support level board, second It is fixedly connected between frame and bottom plate by passing through strip groove bolt cooperating with the jack.

Using the above structure, when needing pair roller barrel to be tested, second support and the is first adjusted according to the length of roller Bolt is passed through inserting in the strip groove and bottom plate on second support level board when being of convenient length by the distance between one bracket Hole cooperation, second support is fixed on bottom plate, by the adjusting to distance between second support and first support, it can be achieved that Dynamic balancing measurement is carried out to the roller of different length.

Further, T-slot is offered on the connecting plate, the bottom of the horizontal part of third bracket is equipped with T-shaped block, the T Shape block is slidably matched with T-slot, and the third bracket is slidably connected with connecting plate by T-shaped block and T-slot；The water of third bracket Flat portion offers pore, and the bottom of connecting plate T-slot offers third threaded hole, between third bracket and connecting plate by across Pore and the bolt that third threaded hole cooperates are affixed.

Using the above structure, when needing pair roller barrel to be tested, sliding third bracket is first passed through to adjust third bracket The distance between first support, so as to suitable distance is able to maintain between motor output shaft and roller main shaft, when distance is closed After suitable, stop sliding third bracket, third threaded hole bolt passed through on the pore and connecting plate of third bracket cooperates, will Third bracket is fixed on connecting plate.

Further, the first support and connecting plate are detachably connected with bottom plate.

Using the above structure, it when needing replacing first support and connecting plate, can conveniently dismantle at any time.

Further, first strip-shaped hole is distributed in the two sides of sliding panel.

The two sides of sliding panel are distributed in using the first strip-shaped hole, can make sliding panel it is more stable be fixed on third branch On frame.
