Description

Technical Field

[0001] This utility model relates to the technical field of machining, specifically a continuous striking device. Background Technology

[0002] In the shaping and cutting process of workpieces, such as in stone processing, rough machining first removes some material and creates a rough shape, followed by fine machining. A common rough machining method involves using a saw blade to cut layer by layer along the axial direction of the cylinder. When the cutting interval is small, all waste material is cut into granules or powder; when the cutting interval is large, the waste material is cut into layers approximately 2-5 cm thick, and then these outer layers are manually chipped away. The former method is not only inefficient but also generates a large amount of dust, causing significant environmental pollution; the latter method is more efficient, but currently requires manual chipping and is labor-intensive, making continuous operation impossible. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention provides a continuous hammering device that replaces manual hammering and chiseling to remove waste materials. It can connect upstream and downstream processes to form an automated production line, greatly improving production efficiency.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0006] The conveying assembly is provided with a conveying channel for conveying workpieces, and the conveying channel is provided with a striking station;

[0007] A lifting and rotating assembly is located at the striking station. The lifting and rotating assembly includes a lifting mechanism and a rotating mechanism. The lifting mechanism is used to lift the workpiece in the striking station to detach from or place it in the conveying channel. The rotating mechanism is used to rotate the workpiece in the striking station.

[0008] A striking assembly is located beside the striking station. The striking assembly includes a striking mechanism for striking the outer peripheral wall of the workpiece in the striking station.

[0009] The beneficial effects of the continuous striking device of this utility model are:

[0010] In operation, the workpiece to be chipped and have its waste removed is first conveyed to the chipping station via a conveyor channel. Then, a lifting mechanism lifts the workpiece from the chipping station to remove it from the conveyor channel. A rotating mechanism then rotates the workpiece while the chipping mechanism strikes its outer perimeter. The combined action of the rotating and chipping mechanisms chips away at the waste layer on the workpiece's surface. After chipping, the workpiece is lowered onto the conveyor channel, which then transports it to the next process. Simultaneously, new workpieces are transported to the chipping station. This process is repeated, connecting the preceding and following processes to form an automated production line, greatly improving production efficiency.

[0011] As a further improvement to the above technical solution, the striking assembly also includes a striking feed mechanism that is connected to the striking mechanism in a transmission manner. The striking feed mechanism is used to drive the striking mechanism to move along the tool advance and retraction direction, and the tool advance and retraction direction is set perpendicular to the rotation axis of the workpiece.

[0012] As a further improvement to the above technical solution, the striking assembly further includes a striking displacement mechanism, which is used to drive the striking mechanism to move along the displacement direction, and the displacement direction is set in the same direction as the rotation axis of the workpiece.

[0013] As a further improvement to the above technical solution, the rotation axis of the rotating mechanism that drives the workpiece to rotate is set in the same direction as the lifting direction of the lifting mechanism that drives the workpiece to lift.

[0014] As a further improvement to the above technical solution, the lifting mechanism includes a lifting platform located on the lower side of the conveying channel and a lifting drive structure that drives the lifting platform to rise and fall.

[0015] The rotating mechanism includes a rotating platform installed on the top of the lifting platform and a rotating drive structure that drives the rotating platform to rotate.

[0040] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0041] Currently, the removal of cutting waste from workpiece 500 still requires manual hammering during the cutting process, which is labor-intensive and cannot be operated continuously. This invention transforms the manual hammering action into a mechanical action, and develops a continuous hammering machine device to replace manual hammering and chiseling to remove waste. It can connect the preceding and following processes to form an automated production line, greatly improving production efficiency.

[0042] like Figure 1 As shown, the continuous striking device of this utility model includes: a conveying component 100, a lifting and rotating component 200, and a striking component 300.

[0043] like Figure 1 As shown, the conveying assembly 100 is provided with a conveying channel 110 for conveying the workpiece 500. The conveying channel 110 has a feeding end connected to the previous process and a discharging end connected to the next process. The conveying channel 110 is provided with a striking station 111 located between the feeding end and the discharging end. The conveying channel 110 conveys the workpiece 500 to the striking station 111 for the waste material striking and chiseling process.

[0044] The lifting and rotating assembly 200 is located at the striking station 111, wherein, as shown in the figure... Figure 5 As shown, the lifting and rotating assembly 200 includes a lifting mechanism 210 and a rotating mechanism 220. The lifting mechanism 210 is used to lift the workpiece 500 in the striking station 111 to detach from or place it in the conveying channel 110. It can be understood that when the workpiece 500 is conveyed to the striking station 111, the lifting mechanism 210 raises the station from the conveying channel 110. At this time, the conveying channel 110 can also convey other workpieces 500 to improve the processing cycle.

[0045] The rotating mechanism 220 is used to drive the workpiece 500 in the striking station 111 to rotate, such as Figure 2 The workpiece 500 shown is an irregular columnar or square material after being cut by the saw blade. The outer surface is waste material. It has been cut into a layered structure 510 with gaps by the saw blade. When hammering, it needs to be hammered along the outer periphery of the workpiece 500. After the workpiece 500 leaves the conveying channel 110, it is driven to rotate by the rotating mechanism 220. The rotation axis of the workpiece 500 is the axis of its own center. If the axis of the workpiece 500's own center is horizontal, then the rotation axis of the workpiece 500 is set horizontally. If the axis of the workpiece 500's own center is vertical, then the rotation axis of the workpiece 500 is set vertically. During rotation, it depends on the axis of the workpiece 500's center. In this embodiment, the rotation axis of the workpiece 500 is set in the up and down direction. That is, the rotation axis of the workpiece 500 driven by the rotating mechanism 220 is set in the same direction as the lifting direction of the workpiece 500 driven by the lifting mechanism 210.

[0046] like Figure 1 As shown, the striking assembly 300 is located beside the striking station 111. The striking assembly 300 includes a striking mechanism 310, which is used to strike the outer peripheral wall of the workpiece 500 in the striking station 111.

[0047] like Figure 3 As shown, in operation, the workpiece 500 to be chipped and have its waste removed is first conveyed to the chipping station 111 via the conveyor channel 110. Then, the lifting mechanism 210 lifts the workpiece 500 in the chipping station 111 to remove it from the conveyor channel 110. After that, the rotating mechanism 220 rotates the workpiece 500 while the chipping mechanism 310 chips the outer peripheral wall of the workpiece 500. Under the synergistic action of the rotating mechanism 220 and the chipping mechanism 310, the waste layer on the outer surface of the workpiece 500 is chipped. After chipping, the workpiece 500 is lowered and placed on the conveyor channel 110, which then conveys the workpiece 500 to the next process. At the same time, a new workpiece 500 is conveyed to the chipping station 111. This process is repeated to connect the preceding and following processes, forming an automated production line that greatly improves production efficiency.

[0048] Furthermore, considering the need to strike workpieces 500 with different shapes, specifications, and diameters, the feed rate needs to be adjusted during the striking process, such as... Figure 1 and Figure 6 As shown, the striking assembly 300 in this embodiment also includes a striking feed mechanism 320 that is connected to the striking mechanism 310 in a transmission manner. The striking feed mechanism 320 is used to drive the striking mechanism 310 to move along the tool advance and retraction direction. The tool advance and retraction direction is set perpendicular to the rotation axis of the workpiece 500. The feed amount of the striking mechanism 310 is adjusted according to the cutting depth of the waste layer to meet the needs of workpieces 500 with different shapes and specifications. During striking, the striking mechanism 310 can be gradually fed by the striking feed mechanism 320 to improve the effect of striking and chiseling away waste.

[0049] Meanwhile, considering the need to adapt to workpieces 500 of different heights, the striking assembly 300 in this embodiment also includes a striking displacement mechanism 330. The striking displacement mechanism 330 is used to drive the striking mechanism 310 to move along the displacement direction. The displacement direction is set in the same direction as the rotation axis of the workpiece 500. In this embodiment, the displacement direction is defined as the left-right direction, while the rotation axis of the workpiece 500 is the up-down direction. During striking, the striking displacement mechanism 330 drives the striking mechanism 310 to reciprocate along the rotation axis of the workpiece 500.

[0050] In this embodiment, driven by the striking feed mechanism 320 and the striking displacement mechanism 330, the striking mechanism 310 has the functions of feeding and automatic lifting, adapting to the striking of workpieces 500 with different diameters and heights, and realizing the striking of irregular materials.

[0051] Among them, the striking feed mechanism 320 and the striking displacement mechanism 330 are respectively a motor, a lead screw, and a linear guide structure, such as... Figure 1 , Figure 6 As shown, in this embodiment, the tapping feed mechanism 320 is installed on the lifting drive end of the tapping shift mechanism 330, while the tapping mechanism 310 is installed on the transverse drive end of the tapping feed mechanism 320. The tapping feed mechanism 320 drives the tapping mechanism 310 to advance and retract the tool through the tapping feed motor 321, while the tapping shift mechanism 330 drives the tapping feed mechanism 320 and the tapping mechanism 310 to rise and fall together through the tapping shift motor 331, so as to adjust the advance and retraction of the tool and the height position.

[0052] In some embodiments, the lifting mechanism 210 can be used to move the workpiece 500 relative to the striking mechanism 310 along the rotation axis of the workpiece 500.

[0053] like Figure 5 As shown, the lifting mechanism 210 of this embodiment includes a lifting platform 211 located below the conveying channel 110 and a lifting drive structure (not shown) that drives the lifting platform 211 to rise and fall. The lifting drive structure can be driven by a hydraulic cylinder, a pneumatic cylinder, or an electric rod, which will not be described in detail here.

[0054] The rotating mechanism 220 in this embodiment includes a rotating platform 221 mounted on top of the lifting platform 211 and a rotating drive structure (not shown) that drives the rotating platform 221 to rotate. The rotating platform 221 is rotatably mounted on top of the lifting platform 211 and supports the workpiece 500, making the overall device more compact and the transmission method simpler. In this embodiment, the rotating function of the rotating mechanism 220 drives the workpiece 500 to rotate and be struck one revolution at a time, while the lifting function of the lifting mechanism 210, in conjunction with the conveying channel 110, is responsible for the receiving and feeding of the workpiece 500.

[0055] In some other embodiments, the lifting mechanism 210 can lift the workpiece 500 by clamping it and then rotate it.

[0056] The rotary drive structure can be driven by a motor and gears or by a motor and pulley; these will not be elaborated on here.

[0057] like Figure 7 As shown, the conveying channel 110 of this embodiment includes at least two conveyor belts 112 arranged side by side at intervals, and the lifting platform 211 is located between the two adjacent conveyor belts 112. The conveyor belts 112 adopt belt conveying or chain conveying.

[0058] like Figure 1As shown, the striking mechanism 310 in this embodiment includes a striking head 311 and a striking drive structure that drives the striking head 311 to swing back and forth, so as to imitate the action of manual striking.

[0059] Specifically, such as Figure 4 As shown, the striking drive structure includes a striking rod 312, a cam 313, an elastic element, a base 315, and a striking motor 316. The striking rod 312 has a swing connection point that is hinged to the base 315 between its two ends. The striking head 311 is connected to one end of the striking rod 312 near the workpiece 500. The elastic element acts between the other end of the striking rod 312 and the base 315. The elastic element is used to keep the outer peripheral wall of the striking rod 312 in contact with the outer peripheral wheel surface of the cam 313. The striking motor 316 drives the cam 313 to rotate, thereby driving the striking rod 312 to swing back and forth. In this embodiment, the elastic element is a spring 314, wherein the two ends of the elastic element abut against the striking rod 312 and the base 315 respectively. The base 315 has a spring seat connected to the spring 314 and a bearing seat hinged to the striking rod 312.

[0060] like Figure 4 As shown, the working principle of the striking drive structure is as follows: the striking motor 316 drives the cam 313 to rotate, which drives the left end of the striking rod 312 to move downward. The spring 314 and the spring seat help the left end of the striking rod 312 to return to its original position. The striking head 311 is installed on the right end of the striking rod 312 to strike by moving up and down.

[0061] like Figure 1 and Figure 3 As shown, the continuous striking device also includes a receiving assembly, which includes a receiving groove 400 located below the striking head 311. The receiving groove 400 is used to receive the waste material knocked down, so as to achieve unified recycling.
