When the area of the wire net formed by the head steel wires is reduced, that is, the machining groove distance of the wire net formed by the head steel wires is reduced, the two first sliding positioning blocks 21 can slide towards the direction close to each other, and the two second sliding positioning blocks 22 slide towards the direction close to each other, so that the area enclosed by the first slits 211 and the second slits 212 is reduced, and the wire net with the reduced area is adapted.

As can be seen from the above embodiments, in the embodiment of the present invention, the sliding assembly 2 includes two oppositely disposed first sliding positioning blocks 21 and two oppositely disposed second sliding positioning blocks 22; the first sliding positioning block 21 and the second sliding positioning block 22 are connected to the top surface of the base 1 in a sliding mode, a first line seam 211 is formed in the first sliding positioning block 21, a second line seam 212 is formed in the second sliding positioning block 22, the first line seam 211 and the second line seam 212 are perpendicular to each other, the first line seam 211 and the second line seam 212 are used for moving of a machine head steel wire stroke, and therefore the size of a grid formed by a straight line where the two first line seams 211 are located and a straight line where the second line seam 212 is located in a surrounding mode can be made to be consistent with a wire net formed by machine head steel wires of the square cutting machine by sliding the first sliding positioning block 21 and the second sliding positioning block 22, and therefore the machine head steel wire net can adapt to wire nets with different processing groove distances.

Furthermore, to realize the sliding of the first slide positioning block 21 and the second slide positioning block 22 on the base 1, in some embodiments, as shown in fig. 1 and 3, two oppositely disposed first sliding rails 11 and two oppositely disposed second sliding rails 12 are disposed on the top surface of the base 1; the projection of the first seam 211 on the top surface of the base 1 is perpendicular to the first slide rail 11, and the projection of the second seam 212 on the top surface of the base 1 is perpendicular to the second slide rail 12; as shown in fig. 6, a first guide slider 212 is disposed at the bottom of the first slide positioning block 21, and the first guide slider 212 protrudes from the bottom of the first slide positioning block 21; as shown in fig. 7, a second rail slider 222 is disposed at the bottom of the second slide positioning block 22, and the second rail slider 222 protrudes from the bottom of the second slide positioning block 22; the first slide positioning block 21 is slidably connected to the first slide rail 11 through the first rail slider 212, and the second slide positioning block 22 is connected to the second slide rail 12 through the second rail slider 222.

It should be noted that the projection of the first seam 211 on the top surface of the base 1 is perpendicular to the first slide rail 11, and the projection of the second seam 212 on the top surface of the base 1 is perpendicular to the second slide rail 12, so that the extending direction of the first slide rail 11 and the extending direction of the second slide rail 12 are perpendicular to each other. And since the first and

second seams

211 and 212 are perpendicular to each other, the projection of the first seam 211 on the top surface of the base 1 is parallel to the second slide rail 12, and the projection of the second seam 212 on the top surface of the base 1 is parallel to the first slide rail 11. Thus, after the first slide positioning blocks 21 are slidably connected in the first slide rail 11 through the first rail sliders 212, the two first slide positioning blocks 21 can be slid in a direction of approaching to or separating from each other. After the second sliding positioning blocks 22 are slidably connected in the second slide rail 12 through the first rail slider 222, the two second sliding positioning blocks 22 can slide toward directions close to or away from each other, and under the limiting effect of the first slide rail 11 and the second slide rail 12, the first seam 211 and the second seam 212 arranged on the first sliding positioning block 21 can be always perpendicular to each other.

It should be noted that, because in the process of the detection of the steel wire net, only need with the gauze embedding in first seam 211 and second seam 212 can, and when the groove distance of the steel wire net changed, only need to make first slide positioning block 21 slide in first slide rail 11, second slide positioning block 22 slides at second slide rail 12 and can match the steel wire net, therefore, the operation is comparatively simple, an operating personnel can accomplish the above-mentioned operation in the whole detection process, and then the process of the detection of steel wire net has been simplified, make things convenient for operating personnel's use.

Further, in order to enable the first sliding positioning block 21 and the second sliding positioning block 22 to slide synchronously, the detection device further comprises a driving component 3; the first sliding positioning block 21 and the second sliding positioning block 22 are both connected to the driving assembly 3, and the driving assembly 3 is used for driving the first sliding positioning block 21 and the second sliding positioning block 22 to slide on the base 1.

Under the condition that the first sliding positioning block 21 and the second sliding positioning block 22 are both connected with the driving assembly 3, the driving assembly 3 can simultaneously drive the first sliding positioning block 21 and the second sliding positioning block 22 to move towards the directions close to or away from each other, so that the sliding distance of the first sliding positioning block is equal to the sliding distance of the second sliding positioning block, the distance between two first seams 211 formed on the two first sliding positioning blocks is equal to the distance between two second seams 212 formed on the two second sliding positioning blocks, and the shape surrounded by the first seams 211 and the second seams 212 is consistent with the shape of a steel wire net.

In some embodiments, the drive assembly 3 comprises a self-locking structure 31 and four movable control levers 32; the first end of each movable control rod 32 is connected with the self-locking structure 31, and the second end of each movable control rod 32 is connected with the first sliding positioning block 21 and the second sliding positioning block 22; the self-locking structure 31 controls the movable control rod 32 to bend or stretch, when the self-locking structure 31 controls the movable control rod 32 to bend, the two second sliding positioning blocks 22 slide towards the direction close to each other, and when the self-locking structure 31 controls the movable control rod 32 to stretch, the two second sliding positioning blocks 22 slide towards the direction far away from each other, and the two second sliding positioning blocks 22 slide towards the direction far away from each other.

It should be noted that, because the first end of each movable control rod 32 is connected to the self-locking structure 31, the state of the four movable control rods 32 can be controlled by the self-locking structure 31 to change, so as to ensure that the first slide positioning block 21 and the second slide positioning block 22 slide synchronously. When the processing groove distance of the wire mesh is reduced, that is, the area of the wire mesh formed by the handpiece steel wire is reduced, the self-locking structure 31 can control the movable control rod 32 to bend, so that the two second sliding positioning blocks 22 slide towards the direction of mutual approaching and the two second sliding positioning blocks 22 slide towards the direction of mutual approaching under the action of the pulling force of the movable control rod 32, and the area of the first wire seam 211 and the area of the second wire seam 212 are reduced so as to adapt to the wire mesh with the reduced area. On the contrary, when the processing groove distance of the gauze that the aircraft nose copper wire formed increases, namely the area increase of the gauze that the aircraft nose copper wire formed, can make self-locking structure 31 control movable control rod 32 straighten, and then two second slide positioning piece 22 slide towards the direction of keeping away from each other, two second slide positioning piece 22 slide towards the direction of keeping away from each other under the thrust effect of movable control rod 32 for the area increase that first seam 211 and second seam 212 enclose, with the gauze of adaptation area increase.

Optionally, as shown in fig. 4, the self-locking structure 31 includes a push rod 311, a housing 312 and a guide caliper 313; one end of the push rod 311 protrudes out of the mouth of the shell 312, the other end of the push rod 311 extends into the inner cavity of the shell 312, the part of the push rod 311 extending into the inner cavity of the shell 312 is clamped with the guide rail caliper 313, and the first ends of the four movable control rods 32 penetrate through the shell 312 and are fixed on the push rod 311; in the case where the push rod 311 moves in a direction away from the mouth of the housing 312, the movable control lever 32 is in a straightened state; in the case where the push rod 311 moves in a direction away from the mouth of the housing 312, the movable control lever 32 is in a bent state.

When the processing groove pitch of the wire mesh is reduced, that is, the area of the wire mesh formed by the head steel wire is reduced, the end of the push rod 311 may be pulled up, so that the push rod 311 moves in a direction approaching the mouth of the housing 312, and the movable control rod 32 is bent, and then the two second slide positioning blocks 22 slide in a direction approaching each other, and the two second slide positioning blocks 22 slide in a direction approaching each other under the pulling force of the movable control rod 32. On the contrary, when the processing groove distance of the wire mesh formed by the head steel wires is increased, that is, the area of the wire mesh formed by the head steel wires is increased, the end of the push rod 311 is pressed, so that the push rod 311 moves in the direction away from the mouth of the housing 312, the movable control rod 32 is in a straightened state, and then under the thrust action of the movable control rod 32, the two second sliding positioning blocks 22 slide in the direction away from each other, and the two second sliding positioning blocks 22 slide in the direction away from each other.

Further, the guide rail caliper 313 is a tooth pitch surface arranged in the shell 312, a sliding groove is formed in a part of the push rod 311 extending into the inner cavity of the shell 312, and the sawtooth surface is clamped in the sliding groove. Thus, under the guidance of the sliding groove, the guide rail caliper 313 slides along the guiding direction of the sliding groove, and under the action of the serrated surface, the part of the push rod 311 extending into the inner cavity of the housing 312 keeps a fixed position at any position of the guide rail caliper 313, so that the bending state of the movable control rod 32 can also be kept at any state, the distance between the two first sliding positioning blocks 21 can be kept at any value, and the distance between the two second sliding positioning blocks 22 can be kept at any value, which is beneficial to the stability of the detection device in a holding structure at any state.

Optionally, the self-locking structure 31 further comprises a self-tapping screw 314; the tapping screw 314 is fixed to the push rod 311 at a position close to the mouth of the housing 312. Thus, the push rod 311 is prevented from being pulled out of the inner cavity of the housing 312 when moving in a direction close to the mouth of the housing 312 by the limit action of the tapping screw 314.

In some embodiments, the movable control lever 32 includes a first movable lever 321 and a second movable lever 322; the first end of the first movable rod 321 is hinged to the first end of the second movable rod 322, the second end of the first movable rod 321 is hinged to the self-locking structure 31, and the second end of the second movable rod 322 is hinged to the first sliding positioning block 21 or the second movable positioning block.

It should be noted that two hinge posts may be fixed on two opposite surfaces of the two first slidably positioning blocks 21 and two opposite surfaces of the two second slidably positioning blocks 22, respectively, and then the second ends of the second movable rods 322 are hinged to the hinge posts respectively. And because the first end of the first movable rod 321 is hinged to the first end of the second movable rod 322, and the second end of the first movable rod 321 is hinged to the self-locking structure 31, the first movable rod 321, the second movable rod 322 and the second movable rod 322 can rotate with each other, when the self-locking structure 31 gives a pulling force to the first movable rod 321, the first movable rod 321 and the second movable rod 322 are gradually straightened, and when the self-locking structure 31 gives a pushing force to the first movable rod 321, an included angle between the first movable rod 321 and the second movable rod 322 is gradually increased, so that a distance between the two first sliding positioning blocks 21 is changed, and a distance between the two second sliding positioning blocks 22 is changed.

Optionally, in some embodiments, as shown in fig. 1, 4 and 5, a first graduation line 13 and a second graduation line 14 are disposed on the top surface of the base 1, and four crystal lines 15 are disposed on the side surface of the base 1; the first scale mark 13 is positioned in a gap between the first sliding positioning block 21 and two adjacent second sliding positioning blocks 22, and the first scale mark 13 is parallel to the first seam 211; the second scale mark 14 is located in a gap between the second slide positioning block 22 and two adjacent first slide positioning blocks 21, and the second scale mark 14 is parallel to the second seam 212; each crystal line 15 extends from the top of the susceptor 1 to the bottom of the susceptor 1, respectively, and each crystal line 15 is perpendicular to the first graduation mark 13 or the second graduation mark 14.

It should be noted that, because the first scale marks 13 are parallel to the first slits 211, and the second scale marks 14 are parallel to the second slits 212, when the wire mesh size is adjusted through the first slits 211 and the second slits 212, the first scale marks 13 and the second scale marks 14 can perform a function of correcting errors, so as to ensure that the four steel wires forming the wire mesh are perpendicular to each other and parallel to each other in the process of moving simultaneously. It should be further noted that each crystal line 15 extends from the top of the susceptor 1 to the bottom of the susceptor 1, and each crystal line 15 is perpendicular to the first scale mark 13 or the second scale mark 14, so that the position of the edge line can be quickly determined by the probe of the squaring machine in the process of finding the crystal line 15 when the crystal line 15 finds the coaxiality in the calibration process of the detection device. Wherein the edge line is a growth edge line of the crystal bar.

Further, in some embodiments, the bottom surface of the base 1 is a magnetic surface, and the bottom surface of the base 1 is provided with the positioning projections 16. Like this, when installing the centre position of the centre gripping head of butt machine or little mesa with detection component and in the square recess that corresponds, can be so that location arch 16 and square recess phase-match to make detection device and square recess carry out the location matching. And because the bottom surface of the base 1 is a magnetic surface, the bottom surface of the base 1 and a clamping head or a small table top of the square cutting machine can be mutually attracted, and the mode detection device falls off in the tool setting process.

As can be seen from the above embodiments, in the embodiment of the present invention, the sliding assembly 2 includes two oppositely disposed first sliding positioning blocks 21 and two oppositely disposed second sliding positioning blocks 22; the first sliding positioning block 21 and the second sliding positioning block 22 are connected to the top surface of the base 1 in a sliding mode, a first line seam 211 is formed in the first sliding positioning block 21, a second line seam 212 is formed in the second sliding positioning block 22, the first line seam 211 and the second line seam 212 are perpendicular to each other, the first line seam 211 and the second line seam 212 are used for moving of a machine head steel wire stroke, and therefore the size of a grid formed by a straight line where the two first line seams 211 are located and a straight line where the second line seam 212 is located in a surrounding mode can be made to be consistent with a wire net formed by machine head steel wires of the square cutting machine by sliding the first sliding positioning block 21 and the second sliding positioning block 22, and therefore the machine head steel wire net can adapt to wire nets with different processing groove distances. When the processing groove distance of the wire mesh is reduced, that is, the area of the wire mesh formed by the head steel wire is reduced, the two first sliding positioning blocks 21 can slide towards the direction of approaching each other, and the two second sliding positioning blocks 22 slide towards the direction of approaching each other, so that the area enclosed by the first slits 211 and the second slits 212 is reduced, and the wire mesh with the reduced area can be adapted. When the processing slot distance of the gauze that the aircraft nose copper wire formed increases, during the area increase of the gauze that the aircraft nose copper wire formed promptly, can make two second slide positioning blocks 22 slide towards the direction of keeping away from each other, two second slide positioning blocks 22 slide towards the direction of keeping away from each other for the area increase that first seam 211 and second seam 212 enclose, with the gauze that the adaptation area increases. To sum up, through the embodiment of the utility model provides a detection device can adapt to the copper wire gauze of different processing groove distances, when the groove distance of copper wire gauze changes, need not to change detection device for the detection of copper wire gauze is more convenient nimble, both can promote the efficiency of proofreading and correct the gauze, can reduce the cost of the detection of copper wire gauze again.
