Description

Technical Field

[0001] The utility model relates to the technical field of highway vehicle chain processing, in particular to a cutting device for chain production equipment. Background Art

[0002] Chains are typically made of a series of interlocking metal links. They are widely used in various applications requiring chain transmission and are the core of road vehicle transmission systems. Chain processing begins by cutting long raw steel bars into shorter bars of a desired length. These bars then undergo a series of processes, including butting, welding, alignment, and surface treatment, before being manufactured into a usable chain. Cutting is a critical step in the production of road bicycle chains. Existing chain cutting methods often suffer from complex operations, sparks flying, and difficult chip handling. These issues not only affect chain production efficiency but also increase worker safety risks.

[0003] Chinese patent document CN221336905U discloses a cutting device for chain production equipment, in which a first electric push rod is fixedly mounted on the bottom outer surface of a horizontal plate and two threaded plates, a second electric push rod is fixedly mounted on the bottom outer surface of the connecting plate, and a cutting blade is fixedly connected to the output end of the second motor. The cutting device of the chain production equipment solves the problem that existing chain production cutting devices can only cut a single chain into two parts at the same time when in use, and when it needs to be cut into multiple sections, it needs to cut the single chain multiple times, resulting in low work efficiency.

[0004] The existing technology has the following problems:

[0005] While the aforementioned device can push the cut strips from the base into a collection bin after cutting, the chips from the base and the strips are mixed together and enter the collection bin, increasing the subsequent cleaning process. Furthermore, the push plate cannot reach the chips inside the cutting groove, making it generally unsuitable for practical use. Furthermore, in the aforementioned device, the portion of the base near the collection bin is unprotected, making it susceptible to flying chips and sparks generated during cutting, increasing safety risks.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figures 1-6 As shown, a cutting device for chain production equipment includes a workbench 1, a cutting assembly 4 is fixedly mounted on the upper right portion of the workbench 1, a plurality of linearly arranged cutting slots are opened in the middle portion of the upper end of the workbench 1, a pusher assembly 2 is fixedly mounted on the upper rear portion of the workbench 1, and a chip cleaning assembly 3 is movably connected to the left and right positions of the rear portion of the pusher assembly 2;

[0029] The pushing assembly 2 includes a mounting plate 21, the lower end of the mounting plate 21 is fixedly installed to the upper rear end of the workbench 1, a moving mechanism 22 is fixedly installed on the top of the mounting plate 21, a rectangular sleeve 23 is fixedly installed on the front of the moving mechanism 22, a plurality of push rods 24 arranged linearly are fixedly installed on the front bottom of the rectangular sleeve 23, a rack 25 is fixedly installed on the right top of the rectangular sleeve 23, a protective frame 26 is fixedly installed on the front end of the workbench 1, a slide groove is provided on the top of the inner wall of the protective frame 26, a baffle 27 is slidably connected to the left and right parts of the inner wall of the slide groove, the upper and left ends of the protective frame 26 are rotatably connected to the rotating shaft 28, and the left and right parts of the outer wall of the rotating shaft 28 are wrapped with fire ropes 29, and the ends of the two fire ropes 29 away from the rotating shaft 28 pass through the top of the protective frame 26 and are fixedly connected to the left and right parts of the upper end of the baffle 27, a gear 210 is fixedly sleeved on the right part of the outer wall of the rotating shaft 28, and the outer surface of the gear 210 is meshed with the lower end of the rack 25;

[0030] The chip cleaning assembly 3 includes a movable plate 31, the left and right sides of the movable plate 31 are slidingly connected to the left and right parts of the inner wall of the rectangular sleeve 23, the upper left part of the rectangular sleeve 23 is threadedly connected to an adjusting screw 32 that passes through the top of the rectangular sleeve 23, the lower end of the adjusting screw 32 is rotatably connected to the upper left part of the movable plate 31, and the lower end of the movable plate 31 is fixedly installed with an L-shaped brush plate 34.

[0031] The pusher assembly 2 can automatically push the cut material on the workbench 1 out. Secondly, when the electric cutting knife 46 cuts the workpiece, the shielding area formed between the rectangular sleeve 23, the protective frame 26 and the baffle 27 can effectively prevent chips and sparks from flying around. After the workpiece is cut, the electric push rod 221 drives the rectangular sleeve 23 to move forward, and the plurality of push rods 24 only push the workpiece on the workbench 1. The rack 25 first contacts the gear 210. During its movement, the gear 210 rotates by meshing with it, thereby causing the rotating shaft 28 to drive the two fire ropes 29 to retract and pull the baffle 27 upward. The upward movement of the baffle 27 exposes the protective frame 26, and the workpiece falls into the storage box 212 through this exposed position, thereby realizing automatic discharge of the workpiece. The above structure has a high degree of automation and can prevent chips and sparks from flying, and is highly practical. The chip cleaning assembly 3 can be used to clean the chips on the workbench 1 and in several cutting grooves. When cleaning is needed, the workpiece in the receiving box 212 can be removed first, and the adjusting screw 32 can be rotated. The adjusting screw 32 is threadedly connected to the rectangular sleeve 23 to drive the movable plate 31 and the brush plate 34 to move downward.

It is highly practical and can separate the collection of chips and workpieces to avoid mixing the two and increasing the subsequent cleaning process, which can save processing time.

[0032] like Figure 3 As shown, the cutting assembly 4 includes an L-shaped fixing frame 41, the lower end of the fixing frame 41 is fixedly installed on the upper right part of the workbench 1, the lower middle part of the top of the fixing frame 41 is rotatably connected with a reverse double-threaded rod 42, and a motor 43 is fixedly installed on the top right side of the fixing frame 41. The output end of the motor 43 passes through the right part of the fixing frame 41 and is fixedly connected to the right end of the reverse double-threaded rod 42, and the left and right parts of the outer wall of the reverse double-threaded rod 42 are both threadedly connected with slides 44.

[0033] The output end of the motor 43 can drive the reverse double-threaded rod 42 to rotate, and the two slides 44 are threadedly connected to the rod and move in opposite directions.

[0034] like Figure 3As shown, sliding rods are fixedly installed at the front and rear positions of the top lower end of the fixed frame 41, the inner walls of the front and rear parts of the two slides 44 are slidably connected to the left and right parts of the outer walls of the two slides, and the lower ends of the two slides 44 are fixedly installed with electric telescopic rods 45, and the lower ends of the two electric telescopic rods 45 are fixedly installed with electric cutting knives 46.

[0035] The movement of the two slides 44 can determine the cutting length of the workpiece. The two electric telescopic rods 45 are used to adjust the height of the two electric cutting knives 46. The two electric cutting knives 46 move downward when rotating at high speed and cooperate with the corresponding cutting grooves to cut the workpiece into multiple sections. The two slides have a limiting effect on the movement of the two slides 44.

[0036] like Figure 5 As shown, the moving mechanism 22 includes an electric push rod 221, the rear portion of the outer wall of the electric push rod 221 is fixedly connected to the middle portion of the upper end of the mounting plate 21, the output end of the electric push rod 221 is fixedly connected to the middle portion of the rear side of the rectangular sleeve 23, and the left and right portions of the upper end of the mounting plate 21 are both slidably connected with guide rods 222, and the front ends of the two guide rods 222 are fixedly connected to the left and right portions of the rear side of the rectangular sleeve 23.

[0037] The moving mechanism 22 is used to push the chips and the cut workpiece. The output end of the electric push rod 221 can drive the rectangular sleeve 23 to move forward, and the two guide rods 222 have a limiting effect on the movement of the rectangular sleeve 23.

[0038] like Figure 2 and Figure 5 As shown, a collecting box 211 is fixedly installed at the front of the lower end of the workbench 1, and a movable groove is opened at the front bottom of the collecting box 211. The left and right inner walls of the movable groove are slidably connected to the accommodating box 212.

[0039] When the receiving box 212 is full, it can be slid out of the movable slot.

[0040] like Figure 4 and Figure 5 As shown, bristles are fixedly mounted on the lower end of the brush plate 34 .

[0041] When the bristles move downward, they can contact the inner walls of several cutting grooves.

[0042] like Figure 5 As shown, the upper right portion of the rectangular sleeve 23 is slidably connected to a limiting rod 33 that passes through the top of the rectangular sleeve 23 , and the lower end of the limiting rod 33 is fixedly connected to the upper right portion of the movable plate 31 .

[0043] The limiting rod 33 limits the movement of the movable plate 31 .

[0044] The working principle of the present invention is as follows: the robotic arm places a workpiece onto the worktable 1 from the left side. The motor 43 is activated, and its output end drives the counter-rotating double-threaded rod 42 to rotate. The two slides 44, threadedly connected to the rods, move in opposite directions. The movement of the two slides 44 determines the cutting length of the workpiece. Two electric telescopic rods 45 are used to adjust the height of the two electric cutting blades 46. The two electric cutting blades 46 move downward during high-speed rotation, cooperating with corresponding cutting grooves to cut the workpiece into multiple sections. The two slides limit the movement of the two slides 44. At the same time, when the electric cutting blades 46 cut the workpiece, the shielding area formed by the rectangular sleeve 23, the protective frame 26, and the baffle 27 effectively prevents chips and sparks from flying.

[0045] After the workpiece is cut, the electric push rod 221 drives the rectangular sleeve 23 to move forward, and several push rods 24 only push the workpiece on the workbench 1. The rack 25 first contacts the gear 210. During its movement, the gear 210 rotates by engaging with it, so that the rotating shaft 28 drives the two fire ropes 29 to retract and pull the baffle 27 upward. The upward movement of the baffle 27 exposes the protective frame 26, and the workpiece falls into the receiving box 212 through this exposed position, thereby realizing automatic discharge of the workpiece. The above structure has a high degree of automation and can prevent chips and sparks from flying.

[0046] If it is necessary to clean the chips on the workbench 1 and in several cutting grooves, the rectangular sleeve 23 is reset and located at the rear of the workbench 1. The workpiece in the receiving box 212 is removed first, and the adjusting screw 32 is rotated. The adjusting screw 32 is threadedly connected to the rectangular sleeve 23 to drive the movable plate 31 and the brush plate 34 to move downward. The bristles at the bottom of the brush plate 34 can sweep the chips into the receiving box 212 when the rectangular sleeve 23 moves forward, and the baffle 27 is driven upward by the rack 25 to facilitate the passage of chips. It is highly practical and can separate the collection of chips and workpieces to avoid mixing the two and increasing the subsequent cleaning process, which can save processing time.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
