Detailed Description

Embodiment one.

The embodiment aims to provide a rapid measuring mechanism which can measure the length of a section bar in real time in the processing process and can also measure sustainable processing operation once.

The application method of the embodiment is as follows:

1. placing a pipe to be processed on a workbench 1, and fixing the pipe by using a clamp; 2. according to the size requirement, the sliding table 8 is pushed to slide in the sliding groove 4 of the supporting plate; 3. observing the mark line 7 of the mark part 6 on the sliding table 8, comparing the relative positions of the mark line 7 and the scales on the top of the supporting plate 2, and stopping the carriage moving when the mark line 7 moves to the appointed scale position; 4. the rotation of the pulley 10 is limited by a limiting mechanism, and the whole carriage is fixed at a specified position; 5. dragging the section bar to enable the end part of the section bar to be level with an extension line where the marking line 7 is positioned; 6. starting a cutting tool to cut the profile; 7. and (5) repeating the step 5.

The purpose of the fixed assembly is to provide the conditions of support (support plate 2), sliding (boss 3) and measurement (scale on top of support plate 2), which are necessary. The cross section of the support plate 2 may be L-shaped or may be other shapes, but it should be fixed at least to the table 1 and satisfy the above-described requirements.

The purpose that marking part 6 was set up is to play the effect of sign, provides more striking, more direct scale sign through the contrast between mark line 7 and the scale, and the workman of being convenient for learn accurate size fast in continuous work just can realize constantly moving the section bar tip after cutting to the position of mark point parallel and level, when the section bar tip moved the position with the mark point parallel and level, even the blind operation of cutting knife, the section bar after the cutting also can satisfy the requirement of appointed length dimension. It should be noted that, due to the limitations of the safety regulations, the cutting blade must be emptied to a certain extent, and the support plate 2 can only be fixed to the edge of the table 1 without allowing the presence of excessive accessories. As is known, the further the profile is from the scale, the greater the error in the results observed by the human eye, and the more often it is necessary to swing up and down during operation to ensure that the profile ends correspond to the scale. But so the effect of quick measurement can not be achieved, on the basis of which, the identification part 6 is arranged, the identification part 6 not only comprises an identification line 7, the identification line 7 is only a drawn line, but also comprises various supports to provide a platform for drawing the identification line 7. Drawing the marking line 7 on the bracket makes the marking line 7 closer to the profile, which is convenient for observation. In theory, the scale on the support plate 2 can also be drawn by more striking colors, but if the whole scale is drawn by striking, the effect is not ideal in practice, because striking needs to be compared to be displayed, and if the whole scale is drawn by striking colors, the whole scale is equivalent to being not striking.

It should be noted that, the viewing angle direction in fig. 1 is a front view angle, but fig. 1 is only a schematic illustration of the prior art, and the worker is facing the front view angle of the cutting device during actual operation, so the front, back, left and right of the embodiment are made according to the angle of the user, specifically, as shown in fig. 2 and 3, when the user works, the cutting knife and the profile are mainly needed to operate and mainly need to pay attention to the position, so the supporting plate 2 fixed on the workbench 1 faces the direction of the cutting knife to the front, and the supporting plate 2 faces the direction of the cutting knife to the rear, and the viewing angle direction is opposite to the front view angle shown in fig. 1.

The number of the sliding legs 9 can be multiple, and each sliding leg 9 corresponds to one pulley 10. The limiting mechanism for limiting the rolling of the pulley 10 can be realized by adopting any prior art, for example, a screw fixing mode of penetrating through the boss 3 and entering into the slideway 5, a plurality of schemes of directly inserting the limiting baffle of the slideway 5 from the upper side, and the like, and if necessary, grooves for accommodating various parts of the limiting mechanism can be formed at two ends of the boss 3, so long as the movement of the pulley 10 can be limited. However, the spacing mechanism preferably adopts a scheme that the telescopic mechanism 13 drives the sliding block 11 and the spacing bar 12 to clamp the pulley 10, the scheme needs to form a cavity a14 communicated with the sliding block in the slideway 5, the sliding block 11 is slidably arranged in the cavity a14, and when the sliding block 11 slides into the slideway 5 from the cavity a14, the spacing bar 12 is contacted with the pulley 10; the limit bar 12 clamps the pulley 10 between the pulley and the slideway 5 when the sliding block 11 continues to slide, and limits the continued movement of the pulley. The telescopic mechanism 13 arranged in the cavity b15 is used for driving the sliding block 11 to move, and the cavity is positioned at two ends of the slideway 5 and is opposite to the cavity a 14. When the telescopic mechanism 13 extends out, the sliding block 11 slides towards the inner side of the cavity a14, and the limiting strip 12 is separated from contact with the pulley 10; the limit bar 12 contacts with the pulley 10 when the telescopic mechanism 13 is contracted.

The telescopic mechanism 13 may be any solution capable of providing telescopic motion, such as a small telescopic motor, but preferably a push-pull electromagnet, the push rod of which is connected to the slider 11.

In order to provide better sliding effect, the sliding of the front end and the rear end of the sliding table 8 is more synchronous, a boss 3 is also arranged at the front end of the supporting plate 2, the structural shape of the boss 3 is completely consistent with that of the boss 3 at the rear end of the supporting plate 2, and the difference is that the mechanism is unlimited only in the boss 3 at the front end. And the two bosses differ in size. The front end of the corresponding sliding table 8 is also connected with a pulley 10 through a supporting leg, and the pulley 10 slides in the slideway 5 of the front end boss 3.

Embodiment two.

The present embodiment differs from the first embodiment only in that the identification portion 6 in the first embodiment is replaced with a variable measuring mechanism.

Since customers abroad or customers in the domestic electronic product export industry usually use units of equal length of inches when meeting export requirements, this increases the workload for workers who are accustomed to metric units, and the top of the support plate 2 in the first embodiment is not easy to open the scales of inches and the like.

To solve this problem, the scale originally drawn on the support plate 2 is changed to be provided on the measuring tape plate 18, and the measuring tape plate 18 is fixed to the support plate 2. On the measuring tape plate 18, different scale units may be arranged side by side, forming a reference to each other. The measuring tape plate 18 is generally larger in size than the support plate 2, so that the original marking portion 6 cannot perform the marking function, and thus a combination of the bracket, the support column 16 and the marking sheet 17 is provided instead. The support extends forward from the front end of the sliding table 8, the support column 16 is fixed on the support, the marking sheet 17 is sheet-shaped, the marking sheet 17 and the measuring tape plate 18 are always kept in contact, the marking sheet 17 is driven to slide when the sliding table 8 slides, the sliding direction of the marking sheet 17 is perpendicular to the length direction of the measuring tape plate 18, and more accurate size indication can be provided. The marking sheet 17 and the supporting column 16 are connected in a sliding way and cannot be separated, so that any existing mode can be adopted to achieve the effect, for example, a groove with a T-shaped cross section is formed in the bottom of the marking sheet 17, the top of the supporting column 16 is correspondingly arranged into a T-shaped corresponding to the groove, and the sliding of the marking sheet 17 can be achieved and the separation of the marking sheet 17 and the supporting column 16 can be limited; the marking sheet 17 has two sliding directions, one sliding along with the sliding table 8 transversely, and the other sliding along with the sliding table 8 is static, so that the marking sheet 17 actively slides towards the measuring tape plate 18 or away from the measuring tape plate 18. When the marking piece 17 slides towards the direction away from the measuring tape plate 18, it points to one row of scales of the measuring tape plate 18, and when it slides towards the measuring tape plate 18, it points to the other row of scales of the measuring tape plate 18, so that the switching between different unit scales is realized, and the effect of variable measuring units is achieved. Regardless of the direction in which the tab 17 itself slides, its sliding direction is perpendicular to the length of the tape plate 18. In order for the patch 17 to function better, it should have a shape that clearly indicates the scale, and may also have a striking color.

The shape capable of cleaning the indication scale can be any shape meeting the requirement that the indication scale has uniqueness when indicating the scale value, such as triangle shape, diamond shape and the like, has the pointer-like effect and can be convenient for quickly identifying the scale.

On the basis of the present embodiment, there is also a modification in which the laser emitter 19 is provided at the bottom of the bracket, and since the marking sheet 17 marks only the size, the end of the profile to be processed can be moved or moved according to the reference of the marking sheet 17 so that the end is flush with the marking sheet 17, but this operation is easy to cause fatigue of eyes of workers. In order to reduce fatigue, a laser emitter 19 is used to emit laser 20 to the workbench 1, and the laser emitter 19 emits laser 20 at the landing position of the workbench 1, namely the position where the end of the profile to be processed should be, so that the profile can be moved more quickly and accurately, and the fatigue of workers is reduced.
