[0002] For strip-shaped products with high dimensional accuracy, large processing volume, and polygonal structure, the stability and processing efficiency of chamfering are essential options, which are related to product yield and cost.

[0003] However, due to inherent dimensional deviations in the product itself, the chamfering process causes some dimensional fluctuations relative to the set dimensions. This can lead to inconsistent chamfering results, resulting in unstable chamfering specifications and quality issues. Furthermore, existing chamfering equipment requires multiple angle adjustments to the product when chamfering its various edges, impacting processing efficiency. Summary of the Invention

[0004] In order to solve the technical problems existing in the background art, the present invention proposes a chamfering device that allows for size fluctuation and a chamfering equipment that completes the chamfering in one step.

[0005] The chamfering device with permissible dimensional fluctuation proposed in this invention includes: a main structure having a feed channel for the workpiece to pass through and a tool feeding channel for mounting or allowing the chamfering tool to enter, wherein:

[0006] The feed channel is a polygonal channel, and the number of sides of the feed channel is the same as the number of sides of the workpiece; the tool feed channel is located at one apex of the feed channel and passes through the apex to communicate with the feed channel;

[0007] The main structure has at least two elastic sliding positioning components inside. Each elastic sliding positioning component includes a pressure block with its end face facing the inside of the feed channel and an elastic element provided on the back of the pressure block to provide extension and retraction power to the pressure block. When the workpiece enters the feed channel, the pressure blocks in each elastic sliding positioning component act on the workpiece respectively, and the resultant force of each pressure block acting on the workpiece is directed towards the tool feeding channel.

[0008] Preferably, the inner wall of the feed channel has a gap reserved at the junction of each two adjacent walls to form a clearance groove.

[0009] Preferably, the end face of the pressure block includes an inclined surface and a plane connected to the inclined surface arranged sequentially along the extension direction of the feed channel. The plane protrudes from the inner wall of the feed channel, and the side of the inclined surface away from the plane is located on the outer side of the feed channel.

[0010] Preferably, the main structure has at least two mounting holes communicating with the feed channel, each elastic sliding positioning element is installed in the mounting hole in a corresponding manner, and the plane of each pressure block extends out of the mounting hole, with the side of the inclined surface of each pressure block away from its plane located in the mounting hole.

[0011] Preferably, the main structure is provided with an assembly hole and a sealing plate on the outer periphery of any of its mounting channels; the sealing plate is fixed to the main structure by threaded fasteners that are compatible with the assembly hole to block the end of the mounting channel away from the feed channel; the end of the elastic element in the elastic sliding positioning member away from its pressure block abuts against or is connected to the sealing plate.

[0012] Preferably, the mounting channel includes a mounting section and a guide section disposed at the bottom of the mounting section and connecting the mounting section with the feed channel; the elastic sliding positioning element also includes a support block, and the pressure block is slidably installed inside the support block; the support block is embedded in the mounting section, one end of the pressure block extends out of the support block to extend into the guide section and form a sliding fit with the guide section, one end of the elastic element is connected to or abuts against the pressure block, and the other end of the elastic element is connected to or abuts against the sealing plate.

[0013] Preferably, the support block has a slide rail and a ball track with one end connected to the slide rail. The pressure block is slidably installed in the slide rail. One end of the elastic element extends into the slide rail to connect with or abut against the pressure block, and the other end extends out of the ball track to connect with or abut against the sealing plate.

[0014] Preferably, the surface of the main structure is provided with recessed areas that match the number of sealing plates, and each mounting channel and assembly hole is set in the corresponding recessed area, with each sealing plate located in the corresponding recessed area.

[0015] Preferably, the sealing plate is a polygonal plate, and the outline shape of the recessed area matches the sealing plate.

[0016] The chamfering device disclosed in this invention, which completes chamfering in one step, includes multiple chamfering devices with permissible size floating as described in any one of claims 1-8. All the chamfering devices with permissible size floating are arranged in sequence, and the feed channels of each chamfering device with permissible size floating are connected in sequence to form a material passage. When the workpiece enters the material passage, the tool feeding channel in each chamfering device with permissible size floating corresponds to different edges of the workpiece.

[0017] Preferably, the number of chamfering devices with permissible size fluctuation is N, where N is equal to the number of edges of the workpiece to be chamfered.

[0018] In this invention, the feeding channel allows workpieces to pass through, while the tool feeding channel is used to mount chamfering tools or to allow the chamfering tools to enter the feed channel. Multiple elastic sliding positioning elements are installed within the main structure. The pressure blocks in each elastic sliding positioning element apply pressure to the workpiece entering the feeding channel, ensuring the chamfered edge of the workpiece is properly positioned. Because the pressure blocks in the elastic sliding positioning elements can elastically expand and contract under the action of their elastic elements, they can adapt to workpiece size fluctuations, ensuring accurate positioning of the workpiece to be chamfered, guaranteeing stable chamfering accuracy, and good quality. Furthermore, by sequentially arranging multiple chamfering devices with interconnected feeding channels to form a material passage, when a workpiece enters the material passage, the tool feeding channels in each chamfering device, which allows for size fluctuations, correspond to different edges of the workpiece, enabling the workpiece to complete all its chamfering in one operation, greatly improving production efficiency.

[0026] Reference Figure 1-3 The chamfering device with permissible dimensional fluctuation proposed in this invention includes: a main structure 1, which has a feed channel 4 for a workpiece 9 to pass through and a tool feeding channel 5 for mounting a chamfering tool or for the chamfering tool to enter, wherein:

[0027] Feed channel 4 is a polygonal channel with the same number of sides as workpiece 9. Tool feed channel 5 is located at one apex of feed channel 4 and extends through the apex to communicate with feed channel 4. When workpiece 9 passes through feed channel 4, one of the edges of workpiece 9 to be chamfered faces tool feed channel 5, thereby causing a chamfering tool located in or fed through tool feed channel 5 to chamfer that edge.

[0028] The main structure 1 has at least two elastic sliding positioning components inside. Each elastic sliding positioning component includes a pressure block 2 with its end face facing the inside of the feed channel 4 and an elastic element 3 set on the back of the pressure block 2 to provide extension and retraction power for the pressure block 2. When the workpiece 9 enters the feed channel 4, the pressure blocks 2 in each elastic sliding positioning component act on the workpiece 9 respectively, and the resultant force of each pressure block 2 acting on the workpiece 9 is directed towards the tool feeding channel 5, so that the chamfered edge of the workpiece 9 is in place in the tool feeding direction. Since the pressure block in the elastic sliding positioning component can elastically extend and retract under the action of its elastic element 3, it can adapt to the size fluctuation of the workpiece 9, ensure the accurate positioning of the chamfered edge of the workpiece 9, and ensure the stability of the chamfering accuracy and good quality.

[0029] Furthermore, since burrs are prone to appear on the edges of the workpiece 9 during the processing, in this embodiment, a gap is reserved at the junction of each two adjacent walls of the feed channel 4 to form a relief groove 12. The relief groove 12 is used to make room for each edge of the workpiece 9, so as to avoid the workpiece 9 not being able to fit properly due to the burrs on its edges, which would affect the chamfering accuracy.

[0030] Furthermore, in this embodiment, the clearance groove 12 is a hole groove centered on the edge of the feed channel 4.

[0031] Furthermore, in this embodiment, the end face of the pressure block 2 includes an inclined surface and a plane connected to the inclined surface, which are sequentially arranged along the extension direction of the feed channel 4. The plane protrudes from the inner wall of the feed channel 4, and the side of the inclined surface away from the plane is located on the outer side of the feed channel 4. During the processing of the workpiece 9, as the workpiece 9 enters the feed channel 4, it first contacts the inclined surface of the pressure block 2, so that the inclined surface of the pressure block 2 gradually guides the workpiece 9 to the plane of the pressure block 2, so that the plane of the pressure block 2 clamps the workpiece 9.

[0032] In this embodiment, the main structure 1 has at least two mounting holes communicating with the feed channel 4. Each elastic sliding positioning component is installed in a corresponding mounting hole, and the plane of each pressure block 2 extends out of the mounting hole. The side of the inclined surface of each pressure block 2 away from its plane is located in the mounting hole. The design of the mounting holes allows for modular design of the main structure 1 and the components in the elastic sliding positioning components, which facilitates processing and saves processing costs.

[0033] Furthermore, the main structure 1 has an assembly hole 6 and a sealing plate 8 on the outer periphery of any of its mounting channels. The sealing plate 8 is fixed to the main structure 1 by threaded fasteners that are compatible with the assembly hole 6 to block the end of the mounting channel away from the feed channel 4. The end of the elastic element 3 in the elastic sliding positioning component away from its pressure block 2 abuts or connects to the sealing plate 8. When it is necessary to adjust the retraction distance of the pressure block 2, simply tighten or loosen the threaded fasteners on the corresponding sealing plate 8 to adjust the distance between the sealing plate 8 and the corresponding pressure block 2, so that the elastic element 3 abutting against the sealing plate 8 drives the pressure block 2 to move forward or backward, thereby adjusting the amount of extension and retraction of the pressure block 2 in the feed channel 4. When it is necessary to inspect or repair the elastic sliding positioning component, simply disassemble the sealing plate 8 to remove the elastic sliding positioning component from the mounting channel.

[0034] Furthermore, the mounting channel includes a mounting section 10 and a guide section 11 located at the bottom of the mounting section 10 and connecting the mounting section 10 with the feed channel 4; the elastic sliding positioning component also includes a support block 7, with the pressure block 2 slidably mounted inside the support block 7; the support block 7 is embedded in the mounting section 10, one end of the pressure block 2 extends out of the support block 7 to reach the guide section 11 and form a sliding fit with the guide section 11, one end of the elastic element 3 is connected to or abuts against the pressure block 2, and the other end of the elastic element 3 is connected to or abuts against the sealing plate 8. The mounting section 10 in the mounting channel limits the support block 7 in the elastic sliding positioning component to ensure that the support block 7 remains fixed, and the guide section 11 in the mounting channel guides the pressure block 2 in the elastic sliding positioning component to ensure that the pressure block 2 expands and contracts stably. This structural design allows the assembly of the elastic sliding positioning component to be completed without any fixing structure. When the sealing plate 8 is opened, the support block 7, along with the pressure block 2 and the elastic element 3 connected to or abutting against the pressure, can be directly removed, greatly simplifying the assembly steps.

[0035] The specific installation structure design of support block 7, pressure block 2, and spring is as follows: Figure 1 As shown: The support block 7 has a slide and a ball track with one end connected to the slide. The pressure block 2 is slidably installed in the slide. One end of the elastic element 3 extends into the slide to connect with or abut against the pressure block 2, and the other end extends out of the ball track to connect with or abut against the sealing plate 8.

[0036] In this embodiment, the surface of the main structure 1 is provided with recessed areas that match the number of sealing plates 8. Each mounting channel and assembly hole 6 is set in the recessed area in a one-to-one correspondence. Each sealing plate 8 is located in the corresponding recessed area to ensure the flatness of the main structure 1.

[0037] Furthermore, the sealing plate 8 is a polygonal plate, and the contour shape of the recessed area matches that of the sealing plate 8. This allows the mounting holes of the sealing plate 8 to directly align with the assembly holes 6 when the sealing plate 8 is placed in the recessed area, facilitating the rapid positioning of the sealing plate 8.

[0038] The specific implementation method is as follows:

[0039] Reference Figure 4 When the workpiece 9 has a triangular structure, the feeding channel 4 is a matching triangular channel. Two elastic sliding positioning components are provided. The two elastic sliding positioning components are located at the two bottom corners of the feeding channel 4, and the extension and retraction direction of the pressure block 2 in the two elastic positioning components is towards the top corner of the feeding channel 4, so that the resultant force of the two acting on the workpiece 9 is towards the top corner where the tool feeding channel 5 is located.

[0040] Reference Figure 3 When the workpiece 9 is a rectangular structure, the feeding channel 4 is a matching rectangular channel. There are two elastic sliding positioning components. The extension and retraction directions of the pressure block 2 in the two elastic sliding positioning components are respectively towards two adjacent sides of the workpiece 9, and the included angle between the two adjacent sides is diagonal to the apex of the tool feeding channel 5, so that the resultant force of the two acting on the workpiece 9 is towards the apex of the tool feeding channel 5.

[0041] Reference Figure 5 When the workpiece 9 has a pentagonal structure, the feeding channel 4 is a matching pentagonal channel. There are three elastic sliding positioning components. The extension and retraction directions of the pressure block 2 in the three elastic sliding positioning components are respectively towards the three sides of the workpiece 9, and the resultant force of the three acting on the workpiece 9 is towards the apex of the tool feeding channel 5.

[0042] Reference Figure 6 When the workpiece 9 has a hexagonal structure, the feeding channel 4 is a matching hexagonal channel. There are two elastic sliding positioning components. The extension and retraction directions of the pressure block 2 in the two elastic sliding positioning components are respectively towards the two sides of the workpiece 9, and the resultant force of the two acting on the workpiece 9 is towards the apex of the tool feeding channel 5.

[0043] Reference Figure 7 The chamfering device proposed in this invention, which completes chamfering in one step, includes multiple chamfering devices with allowable size fluctuation as described above. All chamfering devices with allowable size fluctuation are arranged in sequence, and the feed channels 4 of each chamfering device with allowable size fluctuation are connected in sequence to form a material passage. When the workpiece 9 enters the material passage, the tool feeding channel 5 in each chamfering device with allowable size fluctuation corresponds to different edges of the workpiece 9, thereby completing the chamfering of multiple edges in one step.

[0044] Furthermore, the number of chamfering devices that allow for size fluctuation is N, where N is equal to the number of edges of workpiece 9 to be chamfered, thereby completing the chamfering work of all edges of workpiece 9 to be chamfered at once.

[0045] As can be seen from the above, in this invention, the feeding channel 4 is used for the workpiece 9 to pass through its interior, and the tool feeding channel 5 is used to install the chamfering tool or for the chamfering tool to enter through this channel. Multiple elastic sliding positioning components are provided within the main structure 1, so that the pressure block 2 in each elastic sliding positioning component applies pressure to the workpiece 9 entering the feeding channel 4, causing the chamfered edge of the workpiece 9 to be in place. Furthermore, since the pressure block 2 in the elastic sliding positioning component can elastically expand and contract under the action of its elastic element 3, it can adapt to the size fluctuation of the workpiece, ensuring accurate positioning of the workpiece to be chamfered, guaranteeing the stability of the chamfering accuracy, and good quality. In addition, by sequentially setting multiple chamfering devices and arranging them in sequence, their feeding channels 4 are sequentially connected to form a material passage. When the workpiece 9 enters the material passage, the tool feeding channel 5 in each chamfering device that allows for size fluctuation corresponds to different edges of the workpiece 9, so that the workpiece 9 can complete the chamfering of all its edges at once, greatly improving production efficiency.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
