The application provides a reinforcing bar testing arrangement includes: the positioning device comprises a carrier 10, wherein at least two limiting grooves 11 are formed in the carrier 10, the at least two limiting grooves 11 are arranged at intervals along a first direction, any limiting groove 11 extends along a second direction, and the first direction is intersected with the second direction; the limiting plate 1 is arranged on one side of the carrying platform 10; the distance measuring sensor 2 is arranged on the other side of the carrier 10, and the limiting plate 1 and the distance measuring sensor 2 are arranged oppositely along a second direction; the distance measurement driving mechanism 20 is used for driving the distance measurement sensor 2 to move along a first direction; wherein, microscope carrier 10 is used for the bearing reinforcing bar for the one end of reinforcing bar supports and leans on limiting plate 1, and range finding sensor 2 can detect the other end of reinforcing bar, so that learn the length of reinforcing bar.

Referring to fig. 1, in the illustrated embodiment, the first direction is an up-down direction, the second direction is a left-right direction, and the first direction is perpendicular to the second direction. The carrier 10 is substantially rectangular, five limiting grooves 11 are formed in the upper surface of the carrier 10, and any one limiting groove 11 can accommodate one reinforcing steel bar. During testing, the distance measuring driving mechanism 20 can drive the distance measuring sensor 2 to move along the up-and-down direction; make range sensor 2 top-down or pass through each spacing groove 11 from bottom to top one by one, range sensor 2 can carry out the length measurement to many reinforcing bars in succession, is favorable to improving work efficiency.

After the length measurement of one steel bar is completed, an operator or a feeding and discharging device (such as a robot) can take down the steel bar after the test and place a new steel bar to be tested, and therefore the steel bar testing device provided by the application can continuously work and further improve the working efficiency.

By arranging the limiting groove 11 on the carrying platform 10, on one hand, the positions of a plurality of reinforcing steel bars can be limited, mutual interference among the reinforcing steel bars can be avoided, and the distance measuring sensor 2 can conveniently detect the reinforcing steel bars at a plurality of fixed preset positions; on the other hand, at least partial reinforcing bar can be absorbed in spacing groove 11, with the cell wall contact of spacing groove 11, so, spacing groove 11 can block the reinforcing bar, avoid the reinforcing bar to remove on microscope carrier 10 to guarantee that distance measuring sensor 2 accurately detects the reinforcing bar.

Through setting up limiting plate 1 to make the one end of the reinforcing bar that awaits measuring to support and lean on limiting plate 1, can further inject the material loading position of reinforcing bar. Specifically, in the embodiment shown in fig. 1 and 2, the position-limiting plate 1 is arranged on the left side of the carrier 10, and the distance-measuring sensor 2 is arranged on the right side of the carrier 10; when putting into the reinforcing bar for the reinforcing bar gets into spacing groove 11, and makes the left end of reinforcing bar support and lean on limiting plate 1. As can be easily understood, because the position of the limiting plate 1 is fixed, when the distance measuring sensor 2 moves to a specific detection position during each test, the distance between the distance measuring sensor 2 and the corresponding limiting plate 1 is constant, and after the reinforcing steel bars abut against the limiting plate 1, the positions of one ends of the reinforcing steel bars in the length direction are fixed and uniform; that is, each reinforcing bar inserted into the limiting groove 11 can be ensured to be at a specific feeding position by only making one end of the reinforcing bar abut against the limiting plate 1.

Referring to fig. 2, the distance between the limiting plate 1 and the distance measuring sensor 2 is L, and after a reinforcing steel bar with the length of X is placed into the limiting groove 11 and abuts against the limiting plate 1, the distance measuring sensor 2 detects that the distance between the reinforcing steel bar and the distance measuring sensor is N, and then X = L-N can be obtained through calculation.

Optionally, the distance measuring sensor 2 is a photoelectric sensor or a laser displacement sensor. During the test for ranging sensor 2's work end is just to the reinforcing bar (when the reinforcing bar was in spacing groove 11, as long as make ranging sensor 2 move to relative with this spacing groove 11, can guarantee that ranging sensor 2 detects the reinforcing bar effectively), ranging sensor 2 can output signal, and the signal returns after contacting the reinforcing bar and keeping away from the other end of limiting plate 1, and the processor can calculate the movement distance who obtains the signal, thereby obtains the interval N of ranging sensor 2 and reinforcing bar.

Specifically, when the distance measuring sensor 2 is a laser displacement sensor, the laser displacement sensor transmits laser pulses to the steel bar through the laser transmitter, the laser pulses return to the laser receiver, and the processor can calculate the time required for the laser pulses to encounter the steel bar and return to the receiver according to the pulse frequency of the laser, so that the distance N is calculated. Because laser emitter can launch million laser pulse per second, consequently, the interval N of treater final output is really obtained after the measurement result is averaged by thousands of times, and the numerical value of interval N is more accurate, and the reinforcing bar length X that finally obtains is also more accurate.

Alternatively, the stopper plate 1 is provided on the stage 10. For example, in the embodiment shown in fig. 1 and 2, the position-limiting plate 1 is disposed on the left side surface of the stage 10, and the position-limiting plate 1 is fixedly connected to the stage 10 by screws.

In other embodiments, the limiting plate 1 may be disposed outside the stage 10. The specific position of the limiting plate 1 is not limited in the application, and the distance L between the limiting plate 1 and the distance measuring sensor 2 is definite as long as the relative position of the limiting plate 1 and the distance measuring sensor is fixed.

Optionally, one end of any one of the limiting grooves 11, which is far away from the distance measuring sensor 2, is provided with one limiting plate 1. At this time, the surfaces of the at least two limiting plates 1 contacting the steel bar may or may not be coplanar.

Optionally, one limiting plate 1 faces the plurality of limiting grooves 11, for example, in the embodiment shown in fig. 1, one limiting plate 1 is disposed on the left side of the carrier 10, and the reinforcing steel bar placed in any one of the limiting grooves 11 contacts the limiting plate 1.

Further, when one limiting plate 1 faces the plurality of limiting grooves 11, one side of the limiting plate 1, which is used for contacting the steel bar, is parallel to the first direction. Therefore, after one end of the steel bar placed in any limiting groove 11 contacts the limiting plate 1, the distance between the end and the distance measuring sensor 2 is consistent. For example, in the embodiment shown in fig. 1, the right side surface of the position-limiting plate 1 is used for contacting the reinforcing steel bar, and the right side surface of the position-limiting plate 1 is parallel to the up-down direction, so that the distance between the distance-measuring sensor 2 and the right side surface of the position-limiting plate 1 is not changed no matter where the distance-measuring sensor moves along the first direction.

Optionally, the opening of the limiting groove 11 is flared. Specifically, the groove diameter of at least the opening portion of the stopper groove 11 is gradually reduced from the opening of the stopper groove 11 toward the groove bottom of the stopper groove 11.

For example, fig. 3 shows a V-shaped spacing groove 11, in which the spacing groove 11 includes two groove walls, and one end of the two groove walls is connected. The other ends extend away from each other. For another example, fig. 4 shows a U-shaped spacing groove 11, in which case the spacing groove 11 includes a circular arc groove wall.

The opening through setting up spacing groove 11 is loudspeaker form, and the opening is big, be favorable to putting into of reinforcing bar, and the opening convergent, the cell wall that is close to can block the reinforcing bar, play better limiting displacement.

It needs to supplement that, the reinforcing bar testing arrangement that this application provided is applicable to the reinforcing bar of multiple specification, specifically can refer to fig. 5, and the external diameter of the reinforcing bar of different specifications is different. The opening of the limiting groove 11 is in a horn shape, so that reinforcing steel bars of different specifications can enter the limiting groove 11, for example, the reinforcing steel bar with the smaller outer diameter can be completely sunk into the limiting groove 11, and the reinforcing steel bar with the larger outer diameter is only contacted with the groove wall of the opening part of the limiting groove 11.

Further, in one embodiment, a deepened groove 12 is formed at the bottom of the limiting groove 11.

Referring specifically to fig. 5 and 6, in the illustrated embodiment, the limiting groove 11 and the deepened groove 12 cooperate to form a slot for limiting the reinforcing steel bar. At this moment, whole draw-in groove possesses two groove segments, and spacing groove 11 is located deepening 12 tops, and spacing groove 11 includes two spacing cell walls 11a and 11b, and one of them spacing cell wall 11a links to each other with one side of deepening 12, and another spacing cell wall 11b links to each other with the opposite side of deepening 12, and spacing cell wall 11a and spacing cell wall 11b extend towards the direction of keeping away from the other side for spacing groove 11 is loudspeaker form. The deepening groove 12 can shrink the groove bottom of the limiting groove 11, and the limiting groove 11 is prevented from being opened excessively, or the groove bottom of the limiting groove 11 is prevented from being excessively deep or flat, so that the limiting of the reinforcing steel bar is prevented from being influenced.

In some cases, referring to fig. 5, the surface of the steel bar with a larger outer diameter has a rib extending along the length direction thereof, so that the rib extends into the deepening groove 12, which is beneficial for the clamping groove to accurately limit the steel bar.

Optionally, the width of the deepened groove 12 is slightly larger than the steel bar with the smallest outer diameter in the application range, so that the steel bar with the smallest size can be accurately located in the limiting groove 11 in the application range without sinking into the deepened groove 12, and the distance measuring sensor 2 is favorable for realizing length measurement of the steel bars with various specifications at the preset position.

With continued reference to fig. 6, in the illustrated embodiment, the deepened slots 12 are rectangular. In other embodiments, the deepened groove 12 may also be V-shaped, U-shaped, etc., and the application does not limit the specific configuration of the deepened groove 12.

Because the reinforcing bar testing arrangement that this application provided is applicable to the reinforcing bar of multiple specification, and the external diameter of the reinforcing bar of different specifications is different, consequently, when range sensor 2 moved to predetermineeing the position, the detection of the too big or the reinforcing bar of external diameter undersize of external diameter can't be satisfied to the high possibility. For example, when the working end of the distance measuring sensor 2 is located at a higher position, the detection of the steel bar with a larger outer diameter can be satisfied, but when the outer diameter of the steel bar is too small, the highest point of the steel bar may not be in the detection range of the distance measuring sensor 2, and therefore, the distance measuring sensor 2 cannot detect the steel bar.

For this reason, the reinforcing bar testing arrangement that this application provided still includes: the end plate 3 is arranged opposite to the limiting plate 1; the second guide part 4 extends along the second direction, and the end plate 3 is arranged on the second guide part 4 in a sliding mode, so that the end plate 3 is far away from the limiting plate 1 along the second guide part 4 to facilitate the steel bar placement; during the test, the one end of reinforcing bar is supported and is leaned on limiting plate 1, the other end and is supported and lean on end plate 3.

Specifically, when the steel bar is placed, the end plate 3 slides along the second guide piece 4 and is far away from the limiting plate 1; after the steel bar is placed in, the end plate 3 is moved again, so that the end plate 3 is close to the limiting plate 1 along the second guide piece 4 until the end plate 3 contacts the steel bar and the steel bar is clamped between the end plate 3 and the limiting plate 1. During testing, the distance measuring sensor 2 is driven by the distance measuring driving mechanism 20 to move to the corresponding steel bar, and the end plate 3 is over against the working end of the distance measuring sensor 2; since the end plate 3 can move only in the second direction along the second guide 4, the position of the end plate 3 in the first direction is not changed, and the side of the end plate 3 facing the distance measuring sensor 2 has a certain length and width, so that the end plate 3 can be certainly detected after the distance measuring sensor 2 is moved to the preset position. Guarantee that end plate 3 supports tight reinforcing bar on limiting plate 1, no matter the external diameter of reinforcing bar is why, required data can be detected to range finding sensor 2 homoenergetic.

More specifically, referring to fig. 2, after the distance between the limiting plate 1 and the distance measuring sensor 2 is L, the thickness of the end plate 3 is H, and a steel bar with a length of X is placed into the limiting groove 11 and clamped between the end plate 3 and the limiting plate 1, the distance measuring sensor 2 detects that the distance between the steel bar and the end plate 3 is N, and then X = L-N-H can be obtained through calculation.

In one embodiment, the second guide 4 and the end plate 3 are arranged above the carrier 10. Optionally, the end of the end plate 3 remote from the second guide 4 extends into the deepened slot 12, and the deepened slot 12 can further define the moving direction of the end plate 3, ensuring that the end plate 3 accurately contacts the reinforcing steel bars.

In another embodiment, the second guide 4 and the end plate 3 are provided on the carrier 10. Optionally, the second guide 4 is placed in the deepening groove 12, and at least one end of the end plate 3 connected to the second guide 4 is placed in the deepening groove 12 so that the end plate 3 contacts the reinforcing bars.

In another embodiment, referring to fig. 2, the second guiding element 4 is disposed on the lower surface of the carrier 10, and the end plate 3 passes through the deepening slot 12 and extends out of the limiting slot 11; at this moment, the end of the end plate 3 far away from the second guide piece 4 is convexly arranged outside the carrying platform 10, so that the end plate 3 is favorably ensured to contact with the reinforcing steel bars and conveniently faces to the working end of the distance measuring sensor 2.

Wherein, the second guiding element 4 can adopt guiding components such as a guide rod, a guide rail and the like; the end plate 3 may be any member capable of contacting with a steel bar, such as a plate, a block, or a rod, or may be an induction member used in cooperation with the distance measuring sensor 2.

In one embodiment, an end plate 3 is disposed in any of the retaining grooves 11.

Referring to fig. 2, the second guide 4 is disposed on the lower surface of the carrier 10, and one end of the end plate 3 is slidably connected to the second guide 4, and the other end passes through the limiting groove 11 and protrudes out of the carrier 10.

From this, spacing groove 11 and end plate 3 one-to-one, each reinforcing bar homoenergetic of putting into spacing groove 11 compresses tightly through the end plate 3 that corresponds to in the reinforcing bar homoenergetic of microscope carrier 10 accepts the reinforcing bar of many different lengths simultaneously, and range sensor 2 can detect each reinforcing bar continuously.

In other embodiments, two or more retaining grooves 11 may share one end plate 3. During testing, one limiting groove 11 of the plurality of limiting grooves 11 sharing one end plate 3 is preferably used for receiving the reinforcing steel bars, so that the testing accuracy is guaranteed.

In order to ensure that the end plate 3 abuts against the steel bar on the limiting plate 1, optionally, the steel bar testing device provided by the application further comprises an elastic piece 5, one end of the elastic piece 5 is fixedly arranged, and the other end of the elastic piece 5 is connected with the end plate 3; when the end plate 3 moves along the second guide 4, the elastic member 5 deforms; after the reinforcing bar was arranged in between limiting plate 1 and the end plate 3, elastic component 5 resumeed, can support tightly end plate 3 to limiting plate 1 supports tightly the reinforcing bar.

In one embodiment, one end of the elastic element 5 is fixedly arranged outside the carrier 10, and the elastic element 5 is located on one side of the end plate 3 away from the limiting plate 1; when the reinforcing steel bar is fed, force is applied to the end plate 3 to enable the end plate to be far away from the limiting plate 1, and the elastic piece 5 is compressed; after the reinforcing steel bar enters the limiting groove 11 between the end plate 3 and the limiting plate 1, the force on the end plate 3 is removed, the elastic piece 5 rebounds, and the end plate 3 is actively pushed to move towards the limiting plate 1 and finally abuts against the reinforcing steel bar; ensure that elastic component 5 is in compression state all the time, rebound elastic component 5 can exert thrust to end plate 3 for end plate 3 has the trend towards limiting plate 1 motion, just also makes end plate 3 can keep the state of holding the tight reinforcing bar.

With continued reference to fig. 7, the chassis 6a and the tray 6b are symmetrically arranged, and in order to ensure that the load cell 6 stably supports the carrier 10, the chassis 6a and the tray 6b are respectively provided with four support legs, which can extend the chassis 6a and the tray 6b without excessively increasing the mass of the whole load cell 6.

Further, the reinforcing bar testing arrangement that this application provided still includes marking mechanism 30, and marking mechanism 30 includes: the laser head 31 is used for marking the steel bars; the first driving assembly 32 is used for driving the laser head 31 to move along the second direction; a second driving assembly 33 for driving the laser head 31 to move in a third direction; the first direction, the second direction and the third direction are pairwise vertical.

It needs to be explained that when the elongation of the steel bar is tested, the steel bar needs to be marked; after the test is finished, the stretching condition can be conveniently and visually known by an operator or a machine through the position change of the mark.

This application jets out laser through laser head 31 and marks the reinforcing bar, marks fast, effectual.

Since the laser head 31 has a certain coverage and the coverage is diffused from top to bottom, the height of the laser head 31 is adjusted so that the laser head 31 approaches the stage 10, the range of action of the laser head 31 is reduced, the laser head 31 is far away from the stage 10, and the range of action of the laser head 31 is increased. By arranging the second driving assembly 33, the relative position of the laser head 31 and the carrier 10 in the vertical direction can be adjusted, and a limiting groove for receiving the reinforcing steel bars on the carrier 10 is ensured to be positioned in the coverage range of the laser head 31.

When the reinforcing bar of different batches tested the elongation, the position of beating the mark that needs is also different, through setting up first drive assembly 32, can adjust the position of laser head 31 according to the needs of beating the mark position.

The first driving assembly 32 and the second driving assembly 33 may adopt driving mechanisms such as an electric cylinder and a linear module.

The above examples only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, and these are all within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
