Description

Technical Field

[0001] The utility model belongs to the technical field of dotting machines, and in particular relates to a manual continuous dotting machine. Background Art

[0002] Continuous marking machine is used for marking round steel, flat steel, steel pipe, steel section and other non-ferrous metal materials for tensile testing.

[0003] In the prior art, in order to reduce investment costs, continuous punctuation machines are generally manual. However, when using a manual continuous punctuation machine, it is necessary to ensure that the punctuation needle is perpendicular to the center axis of the sample placed in the sample seat (placing slot). Conventionally, the flip frame usually drives each punctuation needle to be set in a vertical direction, and when each punctuation needle is set in a vertical direction, the length direction just passes through the center axis of the sample. However, because it is necessary to ensure that the head of each punctuation needle is in contact with the sample during marking, and the punctuation needle needs to be slightly pressed by the sample. Therefore, this type of manual continuous punctuation machine can only adapt to samples of one size (diameter or cross-sectional size). When the size of the sample changes, although punctuation can be achieved, the marked points do not meet the standard (the length direction of the punctuation needle does not pass through the center axis of the sample), and the adaptability and practicality are poor.

[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] Please also read Figures 1 to 3 The manual continuous marking machine provided by the utility model is now described. The manual continuous marking machine includes a base 10, a turning frame 20, a dot-marking assembly 30 and an adjustment structure 40. The top of the base 10 has a placement groove for horizontal placement of the sample. The turning frame 20 is rotatably connected to the base 10, and the turning frame 20 is provided with a slide rail portion 24, which is arranged along the radial direction of the rotating shaft between the turning frame 20 and the base 10. The dot-marking assembly 30 is slidably arranged on the slide rail portion 24, and the dot-marking assembly 30 has a plurality of marking ends arranged horizontally in parallel. The dot-marking assembly 30 can be tilted and flipped on the turning frame 20 until the slide rail portion 24 is in a vertical state, and each marking end corresponds to the sample in the placement groove, and then dot the sample in the placement groove. The adjustment structure 40 is arranged on the turning frame 20 and connected to the dot-marking assembly 30, and can adjust the position of the dot-marking assembly 30 on the slide rail portion 24 so that each marking end corresponds to samples of different sizes.

[0044] Compared with the prior art, the manual continuous marking machine provided in this embodiment has a base 10 that can ensure the horizontal setting of the sample to ensure the stable placement of the sample, and the flip frame 20 can drive the dotting assembly 30 and the adjustment structure 40 to flip up and down on the base 10 to ensure avoidance during the sample placement process, which is convenient for the staff to operate. The adjustment structure 40 can drive the dotting assembly 30 to slide on the flip frame 20, and then adjust the distance between each marking end and the placement groove, which can ensure that it can adapt to samples of different sizes, and can ensure that the extension line of the mark left by each marking end on the sample corresponds to the central axis of the sample, which has strong adaptability, can ensure the marking effect, and is highly practical.

[0045] The marked end mentioned in this embodiment corresponds to the sample, that is, the extension line of the marked end passes through the central axis of the sample, and the marked end is in contact with the sample. It should be noted that in order to ensure the marking effect, the marked end usually has to be elastically abutted against the sample.

[0046] In some embodiments, the base 10 may be Figure 2 See the structure shown. Figure 2 The base 10 includes a support frame 11, a sliding seat 12 and a bidirectional lead screw 13. The top of the support frame 11 is provided with a horizontal sliding platform. Two sliding seats 12 are provided, and the two sliding seats 12 are arranged at intervals and are both slidably arranged on the sliding platform. The top of each sliding seat 12 has an open groove, and the open grooves are combined to form a placement groove. The bidirectional lead screw 13 is horizontally rotatably arranged on the support frame 11, and the two ends of the bidirectional lead screw 13 are arranged in opposite rotation directions and are respectively spirally connected with the nut parts arranged at the bottom of the two sliding seats 12, and one end of the bidirectional lead screw 13 is provided with a first crank 14.

[0047] By driving the bidirectional lead screw 13 to rotate through the first crank 14, the two sliding seats 12 can be driven to move away from each other or relative to each other, thereby ensuring that the length of the mounting groove can be adjusted to accommodate samples of different lengths. The structure is simple and easy to operate.

[0048] It should be explained that the extension line of the marked end passes through the central axis of the sample. This is mainly because the extension line of the marked end passes through the central axis of the mounting groove, and each corresponding open groove can be a V-shaped groove.

[0049] In addition, a through long strip opening along the vertical direction can be provided below the sliding platform to ensure the placement of the thread mother part of each sliding seat 12 .

[0050] In some embodiments, the flip frame 20 can be used as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3The flip frame 20 includes a flip rod 21, a connecting rod 22 and a hand-operated frame 23. There are two flip rods 21, which are arranged in parallel and at intervals, and one end of each flip rod 21 is rotatably connected to the base 10. The connecting rod 22 is arranged horizontally, and its two ends are fixedly connected to the two flip rods 21 respectively. The hand-operated frame 23 is arranged at the other end of the two flip rods 21 and can be held by the staff.

[0051] The base 10 is provided with two hinged parts for rotationally connecting the two flip rods 21 .

[0052] The slide rail portion 24 includes two slide rails, and the two slide rails are respectively arranged on the two flip rods 21 .

[0053] The two flip rods 21 and the connecting rod 22 form an H-shaped structure to ensure the connection strength, and the hand-operated frame 23 allows the staff to adjust the pitch and flip of the flip frame 20 as a whole, thereby ensuring that each marked end corresponds to the sample. The setting of the flip frame 20 can ensure the avoidance of the sample during sampling, and can make it more convenient for the staff to place the sample in the most stable manner.

[0054] The provision of the two sliding guide rails can ensure stable sliding of the dotting assembly 30, thereby ensuring the dotting accuracy.

[0055] In some embodiments, the flip bar 21 can be used as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3 A limit block 25 is provided at one end of each flip rod 21 close to the base 10. The limit block 25 can abut against the base 10 after the flip frame 20 flips upward, so that the sliding guide rail is vertically arranged.

[0056] The base 10 is provided with a limiting plane for the limiting block 25 to abut against.

[0057] The setting of the limit block 25 can ensure that when each flip rod 21 is tilted upward to the maximum stroke, each flip rod 21 is set vertically. At this time, each sliding guide rail is set vertically. This structure can ensure that each marking end can accurately and stably correspond to the placement groove to ensure the marking effect.

[0058] In some embodiments, the adjustment structure 40 may be implemented as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3 The adjustment structure 40 includes a nut portion 41 and an adjustment screw 42. The nut portion 41 is disposed on the connecting rod 22, and the nut portion 41 has a threaded hole whose axis is parallel to the length direction of the sliding guide rail. The adjustment screw 42 is threadedly connected to the threaded hole, and one end of the adjustment screw 42 passes through the threaded hole and is rotatably connected to the dotting assembly 30. The adjustment screw 42 is used to rotate to drive the dotting assembly 30 to slide on the sliding guide rail.

[0059] By adjusting the threaded connection between the screw rod 42 and the nut part 41, it can be ensured that the dot-marking assembly 30 is driven to slide on the sliding guide rail as a whole. When the flip rod 21 is set vertically, the height of the dot-marking assembly 30 in the vertical direction can be adjusted, and then the height of each marking end in the vertical direction can be adjusted, which can ensure that each marking end is close to or away from the mounting groove in the vertical direction, and thus can adapt to samples of different sizes, and can ensure that no matter what kind of sample, the extension line of each marking end can pass through the central axis of the sample, thereby ensuring the marking effect and having strong adaptability.

[0060] In some embodiments, the dotting assembly 30 may be implemented as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3 The dotting assembly 30 includes a slide plate 31, a fixed rod 32, a mounting plate 33, a marking needle 34, a spring 35 and a shaking handle 36. There are two slide plates 31, and the two slide plates 31 are slidably connected to the two sliding guide rails. The fixed rod 32 is horizontally arranged, and the two ends are respectively connected to the two slide plates 31, and the fixed rod 32 is rotatably connected to the adjusting screw 42. The mounting plate 33 is spaced apart from the fixed rod 32, and is respectively fixedly connected to the two slide plates 31. A plurality of sliding holes are provided on the mounting plate 33, and each sliding hole is sequentially spaced apart along the spacing direction of the two slide plates 31. The plate surface of the mounting plate 33 is also provided with a through hole corresponding to each sliding hole. There are a plurality of marking needles 34, and each marking needle 34 is slidably arranged in each sliding hole, and one end of each marking needle 34 extends out of the sliding hole, and the end of the marking needle 34 extending out of the sliding hole is the marking end. Each marking needle 34 is also provided with a toggle portion extending out of the through hole. There are multiple springs 35, each spring 35 is set in each slide hole, and is respectively set corresponding to each marking needle 34, which can continuously bounce each marking needle 34 so that each marking needle 34 maintains a tendency to slide out of the slide hole. A rocking handle 36 is rotatably set on the two slides 31, and the rocking handle 36 has a spiral leaf adapted to each toggle part, and the rocking handle 36 can be rotated to toggle each toggle part in a direction away from the sample.

[0061] The rocking handle 36 is provided with a spiral blade, which can ensure that the rocking handle 36 gradually moves the toggle parts during the rotation process, avoiding concentrated force and reducing the work intensity of the staff. Each marking needle 34 extends out of the sliding hole under the action of each spring 35. When the spiral blade moves the toggle part, it can move in the opposite direction and accumulate force. When the spiral blade is separated from the limit of the toggle part, the spring 35 directly pushes the marking needle 34 to move out of the sliding hole, so that the head of the probe hits the sample to leave a mark on the sample.

[0062] In some embodiments, the shaking handle 36 can be used as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3One end of the rocking handle 36 extending from one of the slide plates 31 is provided with a second rocking handle, and the second rocking handle can ensure that the staff can control the rocking handle 36.

[0063] It should be noted that the second crank handle and the first crank handle 14 can be respectively disposed on both sides of the base 10 .

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
