Description

Technical Field

[0001] This utility model relates to the field of workpiece cutting technology, and in particular to a workpiece cutting device. Background Technology

[0002] In the production and processing of workpiece cutting, the workpiece to be cut is usually fixed on a worktable, and then a cutting blade is used to cut the workpiece in half. However, the existing cutting method is not very applicable. For small workpieces, the cutting and fixing operation is inconvenient. At the same time, for workpieces with internal cavities containing objects, cutting using the existing method will also cut the objects inside the cavities in half, making it difficult to remove the objects after cutting. This affects production efficiency, and cutting the workpiece directly in half with a cutting blade will also affect the service life of the cutting blade. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a workpiece cutting device that can quickly cut workpieces and avoid damaging the internal objects of hollow workpieces when cutting them.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A workpiece cutting device includes a cutting assembly and a clamping and conveying assembly. The cutting assembly includes a first cutting blade and a second cutting blade, with a cutting zone provided between the first cutting blade and the second cutting blade. The clamping and conveying assembly includes a clamping module and a conveying module. The clamping module is disposed on the conveying module and is used to clamp and fix the workpiece. The conveying module is used to drive the clamping module to move towards the cutting zone, so that the workpiece on the clamping module passes through the cutting zone. When the workpiece on the clamping module passes through the cutting zone, the first cutting blade and the second cutting blade respectively perform cutting and lifting movements on the workpiece.

[0006] In one embodiment, the cutting assembly further includes a first cutting lifting module and a second cutting lifting module. The first cutting lifting module is connected to the first cutting blade, and the second cutting lifting module is connected to the second cutting blade. The first cutting lifting module is used to drive the first cutting blade to move up and down within the cutting area, and the second cutting lifting module is used to drive the second cutting blade to move up and down within the cutting area.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] 1. The workpiece cutting device of this utility model, by setting up a cutting component and a clamping and conveying component, performs a cutting operation on the workpiece through the cutting and lifting motion of the first cutting blade and the second cutting blade. This allows it to adapt to the cutting operation of workpieces of different specifications, thereby improving the applicability of the overall equipment. At the same time, when cutting hollow workpieces, it can avoid the internal objects of the workpiece being cut in half, so that after the workpiece is opened, the internal objects can be obtained intact.

Attached Figure Description

[0018] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the embodiments will be briefly described below.

[0019] Figure 1 This is a schematic diagram of the workpiece cutting device in one embodiment of the present invention. Detailed Implementation

[0020] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. Please refer to... Figure 1 A workpiece cutting device 10 includes a cutting assembly 100 and a clamping and conveying assembly 200. The cutting assembly 100 includes a first cutting blade 110 and a second cutting blade 120, and a cutting area 130 is provided between the first cutting blade 110 and the second cutting blade 120. The clamping and conveying assembly 200 includes a clamping module 210 and a conveying module 220. The clamping module 210 is disposed on the conveying module 220 and is used to clamp and fix the workpiece. The conveying module 220 is used to drive the clamping module 210 to move towards the cutting area 130 so that the workpiece on the clamping module 210 passes through the cutting area 130. When the workpiece on the clamping module 210 passes through the cutting area 130, the first cutting blade 110 and the second cutting blade 120 respectively perform cutting and lifting movements on the workpiece.

[0021] It should be noted that after the workpiece to be cut is conveyed to the clamping and conveying assembly 200 by manual labor or a corresponding feeding machine, the clamping module 210 clamps and fixes the workpiece by clamping. At this time, the surface of the workpiece to be cut is exposed outside the clamping module 210. In this embodiment, the surface of the workpiece to be cut is the upper surface and the lower surface. The first cutting blade 110 cuts the upper surface of the workpiece, and the second cutting blade 120 cuts the lower surface of the workpiece, thereby cutting the workpiece into two halves. Specifically, when the workpiece cutting device 10 performs a cutting operation on a solid workpiece, the conveying module 220 drives the clamping module 210 to move towards the cutting area 130. When the workpiece on the clamping module 210 just enters the cutting area 130, the first cutting blade 110 and the second cutting blade 120 respectively perform a cutting motion close to the workpiece, thereby descending to the set position to cut the part of the workpiece that has just entered. Since the workpiece is a solid structure, during the cutting process, the first cutting blade 110 and the second cutting blade 120... The workpiece is fixed at a set position so that when the workpiece has completely passed through the cutting zone 130, it can be cut in half by the first cutting blade 110 and the second cutting blade 120. When the workpiece cutting device 10 performs a cutting operation on a hollow workpiece containing an object, the conveying module 220 drives the clamping module 210 to move towards the cutting zone 130. When the workpiece on the clamping module 210 just enters the cutting zone 130, the first cutting blade 110 and the second cutting blade 120 respectively perform a cutting motion close to the workpiece, thereby... The workpiece is cut as it enters the clamping module 210. As the workpieces pass through the cutting zone 130, the first cutting blade 110 and the second cutting blade 120 move up and down to adjust the cutting depth, thus avoiding cutting the internal parts of the workpiece. After the workpieces on the clamping module 210 have completely passed through the cutting zone 130, the first cutting blade 110 and the second cutting blade 120 complete the cutting operation. At this point, the workpiece on the clamping module 210 is cut in half. Under the cutting and lifting movements of the first cutting blade 110 and the second cutting blade 120, the internal parts of the workpiece are not cut. When the workpiece is opened, the complete internal parts can be obtained, and the complete part of the workpiece is inside one half of the workpiece. At the same time, half of the part of the part is exposed outside the workpiece. In this way, the part can be directly removed in the subsequent removal operation, thereby reducing the difficulty of the removal operation, improving production efficiency, and avoiding damage to the workpiece during the removal process, thus improving production quality.In this embodiment, the cutting lifting motion of the first cutting blade 110 and the second cutting blade 120 can be calculated based on the average value of the outer contour and thickness of the actual workpiece, thereby determining the lifting trajectory of the cutting lifting motion of the first cutting blade 110 and the second cutting blade 120. For example, before the workpiece is loaded to the clamping and conveying assembly 200, CCD imaging technology is used to image the workpiece, thereby enabling calculation based on the workpiece imaging data and the set algorithm, and then feeding it back to the cutting assembly 100, thereby determining the lifting trajectory of the cutting lifting motion of the first cutting blade 110 and the second cutting blade 120. The workpiece cutting device 10 of this utility model, by setting a cutting component 100 and a clamping and conveying component 200, performs a cutting operation on the workpiece through the cutting and lifting motion of the first cutting blade 110 and the second cutting blade 120. This allows it to adapt to the cutting operation of workpieces of different specifications, thereby improving the applicability of the overall equipment. At the same time, when cutting hollow workpieces, it can avoid the internal objects of the workpiece being cut in half, so that after the workpiece is opened, the internal objects of the workpiece can be obtained intact. In the subsequent object removal operation, the object can be directly removed, thereby reducing the difficulty of object removal operation, improving production efficiency, and avoiding damage to the workpiece during object removal, thus improving production quality.

[0022] Please refer to it again. Figure 1 In one embodiment, the cutting assembly 100 further includes a first cutting lifting module 140 and a second cutting lifting module 150. The first cutting lifting module 140 is connected to the first cutting blade 110, and the second cutting lifting module 150 is connected to the second cutting blade 120. The first cutting lifting module 140 is used to drive the first cutting blade 110 to move up and down within the cutting area 130, and the second cutting lifting module 150 is used to drive the second cutting blade 120 to move up and down within the cutting area. The first cutting lifting module 140 includes a lifting slide 141 and a lifting drive component 142. The lifting slide 141 is connected to the lifting drive component 142, and the first cutting blade 110 is disposed on the lifting slide 141. In this embodiment, the second cutting lifting module 150 has the same structure as the first cutting lifting module 140. The first cutting blade 110 and the second cutting blade 120 are symmetrically arranged.

[0023] It should be noted that the first cutting blade 110 is mounted on the lifting slide 141, and the lifting drive component 142 is connected to the lifting slide 141. This allows the first cutting blade 110 to perform lifting and cutting motions under the drive of the lifting drive component 142. In this embodiment, the lifting drive component 142 is a motor screw lifting drive component, which allows for adjustment of the lifting displacement of the lifting slide 141. This enables the first cutting blade 110 to adjust its lifting displacement during the cutting operation, thereby achieving lifting and cutting of the workpiece. Similarly, the second cutting lifting module 150 uses the same structure to control the lifting of the second cutting blade 120, allowing the second cutting blade 120 to adjust its lifting displacement during the cutting operation, thus achieving lifting and cutting of the workpiece.

[0024] In one implementation method, please refer again. Figure 1 The cutting assembly 100 further includes a first cutting lateral movement drive module 160 and a second cutting lateral movement drive module 170. The first cutting lateral movement drive module 160 is connected to the first cutting lifting module 140, and the second cutting lateral movement drive module 170 is connected to the second cutting lifting module 150. In this embodiment, both the first cutting lateral movement drive module 160 and the second cutting lateral movement drive module 170 are motor lateral movement drive modules, thus enabling lateral movement drive operation via servo motor drive.

[0025] It should be noted that the first cutting lifting module 140 is mounted on the first cutting transverse drive module 160, and the second cutting lifting module 150 is mounted on the second cutting transverse drive module 170. This allows the first cutting lifting module 140 and the second cutting lifting module 150 to perform transverse movement operations, thereby making the overall equipment more flexible and adaptable to the cutting and processing operations of different workpieces.

[0026] In one implementation method, please refer to Figure 1 The clamping module 210 includes a clamping drive unit 211, a first gripper 212, and a second gripper 213. The clamping drive unit 211 is connected to the first gripper 212 and the second gripper 213 respectively. In this embodiment, the first gripper and the second gripper are symmetrically arranged, and the clamping drive unit 211 is a motor clamping drive unit.

[0027] It should be noted that the clamping drive 211 can be a cylinder drive or a motor screw clamping drive, thereby enabling the first gripper 212 and the second gripper 213 to move closer to or further apart during clamping operations. For example, the clamping drive 211 consists of symmetrically arranged clamping sliders and a motor screw drive structure. The symmetrically arranged clamping sliders are respectively connected to the motor screw drive structure, and the first gripper 212 and the second gripper 213 are respectively disposed on the corresponding clamping sliders. In this way, the clamping drive 211 can control the clamping of the first gripper 212 and the second gripper 213. In this embodiment, the first gripper 212 can be composed of a clamping block and multiple telescopic limiting rods. One end of each telescopic limiting rod slides through the clamping surface of the clamping block. The second gripper has the same structure as the first gripper and is symmetrically arranged. Thus, when the first gripper 212 and the second gripper 213 clamp and fix the workpiece, the corresponding telescopic limiting rod retracts into the clamping block after contacting the workpiece, while the telescopic limiting rod that does not contact the workpiece remains extended. This clamps and fixes the workpiece, and the extended telescopic limiting rods can limit the position of the workpiece, thereby preventing the workpiece from moving during the cutting operation and improving the cutting quality. Furthermore, a spring is fitted on the part of the telescopic limiting rod located inside the clamping block. Thus, the elastic force of the spring can reset the telescopic limiting rod, and the clamping force of the corresponding telescopic limiting rod on the workpiece can be increased under the action of the elastic force of the spring, allowing the workpiece to be clamped and fixed better, thereby further preventing the workpiece from moving during the cutting operation and improving the cutting quality. For example, the conveying module 220 can be a multi-axis conveying module composed of existing transverse modules, lifting modules and rotating modules, thereby enabling transverse conveying, lifting conveying and rotating operations on the clamping module 210. This makes the cutting operation more flexible and can adapt to operations at workstations such as workpiece loading and subsequent object removal, thereby improving the overall automation level of the equipment.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
