Abstract

The utility model discloses an on-line roller detecting device, which comprises a work bench, two supports, four roller wheels and two dial indicators. The two supports are oppositely arranged on the work bench, the roller wheels are pairwise arranged on the supports oppositely, and to-be-detected rollers are arranged on the four roller wheel. The two dial indicators are respectively lapped on the to-be-detected rollers. The on-line roller detecting device can save conveying cost, and is short in detection period and high in detection precision.

Description

The roller on-line measuring device

Technical field

The utility model relates to detection range, relates in particular to the roller on-line measuring device that is applied to stainless steel hot pressing conveying roller.

Background technology

In the STEELMAKING PRODUCTION, the major equipment that molten steel is converted into steel billet is exactly a fan-shaped section.By steel-drawing machine steel billet is introduced fan-shaped section when molten steel injects crystallizer, the main effect of fan-shaped section in this process is to correct and transporting steel billet, carries piecemeal until final steel billet then and becomes a useful person.Fan-shaped section is formed by 1～14 section, and every section roller by different size is installed and formed.Mainly be one section Φ 140 totally 3 groups each 10 (general assembly (TW) is 1800kg), two sections Φ 180 totally 3 groups each 26 (general assembly (TW) is 7690.8kg), three sections～four sections Φ 230 totally 20 and 2 driven rollers, five sections～eight sections Φ 260 totally 20 and 2 driven rollers, nine sections～14 sections Φ 290 totally 24 and 2 these five kinds of specifications of driven roller.

Because the steel billet temperature that comes out from crystallizer is very high, so the roller damaged condition of Shi Yonging is very serious on line, thereby after each section roller uses certain hour on line, all must carry out regular finishing, all rollers all will carry out the detection of precision and concentricity after disassembling.The existing step that detects roller is: at first roll off the production line in the roller scene; Then, the roller that rolls off the production line is checked with vehicle transport to special purpose machine tool, if qualified, vehicle is transported the scene back and reached the standard grade, and is how defective, repairs, and transports back to the scene with vehicle then and reaches the standard grade.There are the following problems for aforesaid way:

1. conveying roller transportation by lighter convenience is low:

Hot rolling conveying roller rolls off the production line via the steelworks scene, through being transported to of vehicle detect on-the-spot detection lathe by special use detect whether qualified.

1. unacceptable product: if test result is defective, carry out the reparation of specialty again, transport the conveying roller that meets technical requirement after repairing back the steelworks scene, and the work of reaching the standard grade.

2. certified products:, can directly send the roller scene back to and carry out work through transportation if testing result is qualified.

In this process, no matter whether conveying roller is certified products, all need to travel to and fro between the scene of detection through the transportation of vehicle, thus the convenience that has increased the cost of transportation by lighter and reduced transportation by lighter.At present, take two-way time about 40 minutes, the shipment of vehicle, wait for shipment and unload uncertain factor in the transportation by lighter process that this three of time of roller is, can't obtain controlled fully.

2. sense cycle and precision are not enough:

Traditional conveying roller detection time by get on or off the bus, transfer in the spindle nose school, the roll surface school transfers three parts to form, 50 minutes consuming time, add time of transportation, the complete sense cycle of a conveying roller needs 90 minutes, for the production capacity of production scene has increased burden, the production discrepancy easily takes place.The accuracy of detection of conveying roller also has close association with the detection lathe that detects the scene on the other hand, because the detection scene mostly is the age than equipment morning, and the precision and the program process of the instability influence measurement verification of equipment.

3. it is too high that conveying roller detects cost:

Roller detection cost has comprised the cost of getting on or off the bus when transportation cost and roller detect, and the conventional secondary cost that detection method produced is unavoidable, accounts for more than 50% of total cost.

Summary of the invention

The purpose of this utility model provides a kind of roller on-line measuring device, and this device sense cycle is short, and it is low to detect cost.

The utility model to achieve the above object, the technical scheme of being taked is:

A kind of roller on-line measuring device comprises worktable, two supports, four rolling and dial gauges, and two stands is installed on the worktable relatively; Four rolling is installed on relatively respectively on two supports in twos, and roller to be measured is positioned on this four rolling; Dial gauge rides on the roller respectively.

Offer dovetail groove on the described worktable, described support lower end is provided with positioning key, and described support bottom is arranged in dovetail groove by positioning key, and is connected and fixed with worktable.

Described frame bottom comprises the v-depression that is positioned at below, described gap, described roller by Bearing Installation on the two side of groove.

Beneficial effect of the present utility model is:

1, the utility model can direct at the scene pair of rollers detect, and sense cycle is short, the detection cost is low, accuracy of detection is high.

2, roller is positioned on the roller of v connected in star, and roller is the line contact with contacting of roller, and this way of contact has improved coiling the property of roller in that this class build and all bigger roller of weight are carried out the school timing, thereby makes the calibration workpiece lighter.V-depression is the position of may command roller school timing more, and roller double swerve and moving up and down can not take place to occur in the accent process of school, and the school of workpiece transfers precision to be guaranteed, and realizes that accurately transfer location and school, and error is transferred in the school that is not prone in the manual operation.

Fig. 2 is the vertical view of roller on-line measuring device;

Fig. 3 is the structural representation of roller on-line measuring device when user mode.

Embodiment

Further specify architectural feature of the present utility model below in conjunction with accompanying drawing.

As shown in Figure 1 to Figure 3, the utility model roller on-line equipment comprises worktable 1, two supports 2,2 ', four rolling 3,3 ' and dial gauge 4, and whether this device is qualified in order to the roller 5 that detects fan-shaped section.

Offer dovetail groove 11 on the worktable 1.

Two supports 2,2 ' are installed on the worktable 1 relatively, comprise v-depression 21 on the support 2 (is example with support 2), and support 2 bottoms are stuck in worktable 1 dovetail groove 11 by positioning key 22, and are connected and fixed by trapezoidal screw and worktable 1.

Four rolling 3,3 ' is relative in twos, and by Bearing Installation on the sidewall 211 of the groove 21 of support 2.

Dial gauge 4 is set up on roller 5 to be measured.

As shown in Figure 3, when the utility model when detecting roller 5, roller 5 is placed on the roller 3, then dial gauge 4 is ridden on the roller 5, with hand 5 one weeks of rotary rollers, if roller 5 diameter run-outs are at 0～0.01mm, then roller 5 is qualified, the use of directly roller 5 being reached the standard grade then; If the diameter run-out of roller 5 is then defective greater than 0.01mm, roller 5 need be transported to special purpose machine tool reparation.

In sum, therefore the utility model, can save the conveying cost owing to can direct at the scene pair of rollers 5 detect, and sense cycle is short, the accuracy of detection height.
