[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1-Figure 3 The utility model provides an embodiment: a steel bar marking machine for steel inspection, including a shell 1, the shell 1 is the main body of the steel bar marking machine, which is a prior art well known to professionals in the field and will not be described in detail here. A clamping mechanism 2 is provided on the top outer wall of the shell 1, and the steel bar can be placed in the clamping mechanism 2. The clamping mechanism 2 can clamp and fix steel bars of different diameters, and the fixing effect is better and the adaptability is higher.

[0035] Reference Figure 2-Figure 4 The clamping mechanism 2 includes a moving plate 201, which is slidably connected to the outer wall of the top of the housing 1. The outer wall of the moving plate 201 is provided with multiple sets of card slots 213. The arrangement of the multiple sets of card slots 213 allows the rotating plate 202 to be rotated to multiple angles for fixing, thereby adjusting and fixing the distance between the two sets of clamping plates 203. The inner wall of the moving plate 201 is rotatably connected to the rotating plate 202. The outer wall of the rotating plate 202 is provided with an oblique groove 208. The oblique groove 208 There are two groups. When the rotating plate 202 rotates, the inner wall of the inclined groove 208 generates a squeezing force on the outer wall of the splint 203, so that the splint 203 moves along the inner wall of the inclined groove 208. The inner wall of the inclined groove 208 is slidably connected with the splint 203. The outer wall of the movable plate 201 is provided with two groups of transversely symmetrical through grooves. The outer wall of the splint 203 slides on the inner wall of the through grooves. The through grooves can guide the splint 203, so that the splint 203 maintains a transverse moving state when moving.

[0036] Reference Figure 2-Figure 4The outer wall of the clamping plate 203 is fixedly connected with a rubber pad 204, which can increase the friction with the steel bar to make the fixation more stable. The outer wall of the rotating plate 202 is fixedly connected with an operating rod 205, and the operating rod 205 penetrates the outer wall of the movable plate 201. The rotating plate 202 can be driven to rotate by rotating the operating rod 205, thereby driving the clamping plate 203 to move. The inner wall of the operating rod 205 is elastically connected with a block 207 through a reset spring A206. When the operating rod 205 is pulled, the reset spring A206 is forced to contract, so that the block 207 is out of contact with the slot 213.

[0037] Reference Figure 2-Figure 4 One end of the return spring A206 is fixedly connected to the outer wall of the block 207, and the other end of the return spring A206 is fixedly connected to the inner wall of the operating rod 205. When the operating rod 205 is rotated, the rotating plate 202 rotates, and under the guidance of the two groups of through grooves on the outer wall of the movable plate 201, the two groups of clamping plates 203 are driven to move horizontally. The outer wall of the block 207 is slidably connected to the inner wall of the operating rod 205, and the block 207 is engaged with the slot 213. When the clamping plate 203 moves to fit the outer walls of both sides of the steel bar, the rotation of the operating rod 205 can be stopped, so that the return spring A206 drives the block 207 to pop out outward due to its own elastic force and engages with the slot 213, thereby fixing the rotating plate 202 and the clamping plate 203.

[0038] Reference Figure 5 The inner wall of the bottom end of the shell 1 is elastically connected to the bottom plate 210 through an elastic telescopic rod 209. One end of the elastic telescopic rod 209 is fixedly connected to the inner wall of the bottom end of the shell 1, and the other end of the elastic telescopic rod 209 is fixedly connected to the outer wall of the bottom end of the bottom plate 210. When the steel bar is placed on the bottom plate 210, the elastic telescopic rod 209 is forced to shrink, driving the bottom plate 210 to move downward. The outer wall of the bottom plate 210 is fixedly connected with a rubber pad 204, which can increase the friction between the steel bar and the bottom plate 210, so that the rubber pad 204 can be used to increase the friction between the steel bar and the bottom plate 210 during the punctuation process. The steel bar is more stable, and the right inner wall of the shell 1 is elastically connected to the cover plate 211 through the telescopic spring A212. The cover plate 211 can press down and fix one end of the steel bar. One end of the telescopic spring A212 is fixedly connected to the outer wall of the cover plate 211, and the other end of the telescopic spring A212 is fixedly connected to the inner wall of the shell 1. When the steel bar is placed on the bottom plate 210, the cover plate 211 can be moved upward first, the telescopic spring A212 is stretched by force, and then the steel bar is moved to make it contact with the right outer wall of the shell 1.

[0039] Reference Figure 1 , Figure 5The outer wall of the cover plate 211 is slidably connected to the inner wall of the shell 1. At this time, the elastic force of the telescopic spring A212 drives the cover plate 211 to rebound downward and reset, so that the steel bar can be pressed down and assisted in fixation. A limit assembly is provided on the outer wall of the movable plate 201. The position of the movable plate 201 can be adjusted by the limit assembly to adapt to steel bars of different lengths. The outer wall of the shell 1 is provided with a punctuation mechanism 4, and the steel bar can be punctuated by the punctuation mechanism 4, which is a prior art.

[0040] Reference Figure 2 The limiting assembly includes a fixed block 301, which is fixedly connected to the outer wall of the movable plate 201. When the fixed block 301 is moved, the movable plate 201 can be driven to move, and fixing the fixed block 301 can fix the movable plate 201 at the same time. The inner wall of the fixed block 301 is elastically connected to a wedge block A303 through a return spring B302. The arc surface of the wedge block A303 remains facing the direction of the movable plate 201 to facilitate the movable plate 201 to move to the right.

[0041] Reference Figure 2 One end of the return spring B302 is fixedly connected to the outer wall of the wedge block A303, and the other end of the return spring B302 is fixedly connected to the inner wall of the fixed block 301. When the steel bar is placed on the bottom plate 210 and both ends of the steel bar are in contact with the movable plate 201 and the right outer wall of the shell 1, the movable plate 201 can be fixed by the wedge block A303, so that the movable plate 201 cannot move to the left, thereby maintaining the fixing effect.

[0042] Reference Figure 2 The outer wall of the wedge block A303 is slidably connected to the inner wall of the fixed block 301, and the top outer wall of the wedge block A303 is fixedly connected with a pull rod 305. When the pull rod 305 is pulled upward, the wedge block A303 can be disengaged from the groove 304, thereby releasing the limit of the fixed block 301 and the movable plate 201, and the movable plate 201 is moved to the left to release the fixing effect of the steel bar. The top outer wall of the shell 1 is provided with multiple groups of grooves 304, and the wedge block A303 is clamped with the groove 304. The multiple groups of grooves 304 can move the movable plate 201 to multiple positions and fix it to adapt to steel bars of different lengths, and the adaptability is higher.

[0043] Reference Figure 6The punctuation mechanism 4 includes a slider 401, which is slidably connected to the outer wall of the shell 1. A controller is provided in the shell 1, and the slider 401 can be driven to move horizontally to perform punctuation. It is a prior art. The inner wall of the slider 401 is elastically connected to the wedge block B402 through a telescopic spring B403. The telescopic spring B403 and the wedge block B402 are each provided with two groups and symmetrically distributed on both sides of the slider 401. One end of the telescopic spring B403 is fixedly connected to the outer wall of the wedge block B402, and the other end of the telescopic spring B403 is fixedly connected to the inner wall of the slider 401. The outer wall of the punctuation pen 404 is provided with two sets of circular grooves. When the punctuation pen 404 is installed, the circular grooves squeeze the arc surface of the wedge block B402, so that the wedge block B402 moves inward along the inner wall of the slider 401. The outer wall of the wedge block B402 is slidably connected to the inner wall of the slider 401. The outer wall of the slider 401 is clamped with the punctuation pen 404. The punctuation pen 404 is the prior art. When the punctuation pen 404 is installed, the wedge block B402 pops outward due to the elastic force of the telescopic spring B403 itself, and contacts with the outer walls on both sides of the punctuation pen 404, thereby fixing the punctuation pen 404.

[0044] Working principle: The operator can first place the steel bars on the bottom plate 210, and the elastic telescopic rod 209 will be forced to shrink, driving the bottom plate 210 to move downward to support the steel bars. Then, when the position of the movable plate 201 can be adjusted according to the length of the steel bars, the operator can pull the pull rod 305 upward to disengage the wedge block A303 from the groove 304, and release the limit between the fixed block 301 and the movable plate 201, so that the movable plate 201 can be moved to the left to accommodate the longer steel bars. When the steel bars are shorter, the movable plate 201 can be directly moved to the right, and the inner wall of the groove 304 produces an extrusion force on the arc surface of the wedge block A303, so that the wedge block A303 continuously moves upward along the inner wall of the fixed block 301, and the movable plate 201 can be moved.

[0045] At this time, the operator can move the cover plate 211 upward to stretch the telescopic spring A212. When one end of the steel bar contacts the outer wall of the shell 1, the cover plate 211 moves downward and resets due to the elastic force of the telescopic spring A212 itself, thereby assisting in fixing the steel bar. When the movable plate 201 and the outer wall of the shell 1 are in contact with both ends of the steel bar, the wedge block A303 pops up downward due to the elastic force of the reset spring B302 itself, and the straight surface of the wedge block A303 contacts the inner wall of the groove 304, thereby limiting the movable plate 201 in one direction, preventing the movable plate 201 from moving to the left, and thus fixing the steel bar.

[0046] The operator can then pull the block 207 outward to disengage the block 207 from the slot 213, and then rotate the operating rod 205 to make the rotating plate 202 rotate synchronously. The inclined groove 208 generates a squeezing force on the outer wall of the clamping plate 203, and through the guiding effect of the through groove on the outer wall of the movable plate 201, the clamping plate 203 is moved horizontally to the sides or the middle, so that the distance between the two groups of clamping plates 203 can be adjusted according to the diameter of the steel bar, so that the clamping plate 203 fits the surface of the steel bar, and the rubber pad 204 can increase the friction force on the steel bar, making the steel bar more stable. When the steel bar is fixed, the reset spring A206 drives the block 207 to pop out outward due to its own elastic force and engage with the slot 213, so that the rotating plate 202 can be fixed, thereby fixing the position of the two groups of clamping plates 203, clamping and fixing the steel bar, and the fixing effect is better. During the punctuation process, the vibration of the device will not affect the steel bar.

[0047] Through the above steps, steel bars of different sizes can be clamped and fixed, and the controller inside the shell 1 can be used to control the slider 401 to move horizontally, and punctuation can be performed through the punctuation pen 404. When the punctuation pen 404 is damaged after a long period of use and needs to be replaced, the two sets of wedge blocks B402 can be pressed inward to break contact with the outer wall of the punctuation pen 404, and the punctuation pen 404 can be removed. Then a new punctuation pen 404 can be taken out and installed on the outer wall of the slider 401. At this time, the two sets of circular grooves on the outer wall of the punctuation pen 404 produce a squeezing force on the arc surface of the wedge block B402, so that the wedge block B402 moves inward along the inner wall of the slider 401. When the punctuation pen 404 is installed, the wedge block B402 pops out due to the elastic force of the telescopic spring B403 itself and fixes the punctuation pen 404, so that the punctuation pen 404 can be replaced conveniently and quickly, and there is no need to install and disassemble by turning the bolts multiple times, which is more convenient and quick.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
