[0026] Reference Figure 1-3 The chamfering device allowing size floating proposed by the present invention comprises: a main structure 1, which has a feed channel 4 for a workpiece 9 to pass through and a tool feed channel 5 for installing a chamfering tool or for the chamfering tool to enter, wherein:

[0027] The feed channel 4 is a polygonal channel, and the number of sides of the feed channel 4 is the same as the number of sides of the workpiece 9. The tool feed channel 5 is located at a vertex of the feed channel 4 and penetrates the vertex to communicate with the feed channel 4. When the workpiece 9 passes through the feed channel 4, one of the edges to be chamfered of the workpiece 9 faces the tool feed channel 5, and then the chamfering tool set in the tool feed channel 5 or fed by the tool feed channel 5 chamfers the edge to be chamfered.

[0028] At least two elastic sliding positioning members are arranged inside the main structure 1, each of which includes a pressure block 2 with its end face facing the inside of the feed channel 4 and an elastic element 3 arranged on the back of the pressure block 2 to provide expansion and contraction power for the pressure block 2. When the workpiece 9 enters the feed channel 4, the pressure blocks 2 in each elastic sliding positioning member act on the workpiece 9 respectively, and the combined force of each pressure block 2 acting on the workpiece 9 is directed toward the tool feed channel 5, so that the edge of the workpiece 9 to be chamfered is pressed into place in the feed direction. Since the pressure blocks in the elastic sliding positioning members can be elastically expanded and contracted under the action of their elastic elements 3, they can adapt to the size floating of the workpiece 9, ensure the precise positioning of the workpiece 9 to be chamfered, and ensure the stability of the chamfering accuracy and good quality.

[0029] In addition, since burrs are likely to appear on the edges of the workpiece 9 during the processing, the present embodiment reserves a gap on the inner wall of the feed channel 4 at the junction of each two adjacent walls to form a clearance groove 12, so that the clearance groove 12 can be used to make way for the edges of the workpiece 9 to avoid the problem that the workpiece 9 cannot be properly abutted due to the burrs on its edges, thereby affecting the chamfering accuracy.

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

[0031] Furthermore, in this embodiment, the end face of the pressing block 2 includes an inclined surface sequentially arranged along the extension direction of the feed channel 4 and a plane connected with the inclined surface, the plane protrudes from the inner side wall of the feed channel 4, and the side of the inclined surface away from the plane is located outside the feed channel 4. When the workpiece 9 is in the process of machining, the workpiece 9 first contacts the inclined surface of the pressing block 2 in the process of entering the feed channel 4, so that the inclined surface of the pressing block 2 is used to gradually guide the workpiece 9 to the plane of the pressing block 2, so that the plane of the pressing block 2 clamps the workpiece 9.

[0032] In this embodiment, the main structure 1 has at least two mounting holes connected to the feed channel 4, and each elastic sliding positioning member is installed in each mounting hole in a one-to-one correspondence, and the plane of each pressing block 2 extends out of the mounting hole, and the side of the inclined surface of each pressing block 2 away from its plane is located in the mounting hole. The design of the mounting hole can modularize the components of the main structure 1 and the elastic sliding positioning member, which is convenient for processing and can save processing costs.

[0033] Furthermore, the main structure 1 is provided with assembly holes 6 and sealing plates 8 on the periphery of any installation channel thereof; the sealing plates 8 are fixed to the main structure 1 by threaded fasteners adapted to the assembly holes 6 to block the end of the installation channel away from the feed channel 4; the elastic element 3 in the elastic sliding positioning piece is against or connected to the sealing plate 8 at one end away from its pressing block 2. When it is necessary to adjust the retraction distance of the pressing block 2, it is only necessary to tighten or loosen the threaded fasteners on the corresponding sealing plate 8 to adjust the spacing between the sealing plate 8 and the corresponding pressing block 2, so that the elastic element 3 against the sealing plate 8 drives the pressing block 2 to move forward or backward, thereby adjusting the expansion and contraction amount of the pressing block 2 in the feed channel 4. When it is necessary to inspect or repair the elastic sliding positioning piece, it is only necessary to disassemble the sealing plate 8 to remove the elastic sliding positioning piece from the installation channel.

[0034] Furthermore, the installation channel includes an installation section 10 and a guide section 11 arranged at the bottom of the installation section 10 and connecting the installation section 10 with the feed channel 4; the elastic sliding positioning member also includes a support block 7, and the pressure block 2 is slidably installed inside the support block 7; the support block 7 is embedded in the installation section 10, one end of the pressure block 2 extends out of the support block 7 to extend into the guide section 11 and forms 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 installation section 10 in the installation channel limits the support block 7 in the elastic sliding positioning member to ensure that the support block 7 remains fixed, and the guide section 11 in the installation channel guides the pressure block 2 in the elastic sliding positioning member to ensure that the pressure block 2 is stable in expansion and contraction. This structural design makes it possible to assemble the elastic sliding positioning member without any fixed structure. When the sealing plate 8 is opened, the support block 7 together with the elastic element 3 arranged on the pressure block 2 and connected or abutted with the pressure can be directly taken out, which greatly simplifies the assembly steps.

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

[0036] In this embodiment, the surface of the main structure 1 is provided with recessed areas matching the number of sealing plates 8, and each installation channel and assembly hole 6 is arranged in each recessed area in a one-to-one correspondence, and each sealing plate 8 is located in the corresponding recessed area to ensure the smooth appearance of the main structure 1.

[0037] Furthermore, the sealing plate 8 is a polygonal plate, and the contour of the recessed area matches the sealing plate 8. When the sealing plate 8 is placed in the recessed area, the mounting hole of the sealing plate 8 directly enters a coaxial state with the assembly hole 6, and this structural design facilitates the rapid positioning of the sealing plate 8.

[0038] The specific embodiments are as follows:

[0039] Reference Figure 4 When the workpiece 9 is a triangular structure, the feed channel 4 is a triangular channel that matches it, and two elastic sliding positioning members are provided. The two elastic sliding positioning members are respectively located at the two bottom corners of the feed channel 4, and the telescopic directions of the pressing blocks 2 in the two elastic positioning members are both toward the top corner of the feed channel 4, so that the combined force of the two acting on the workpiece 9 is toward the top corner where the knife feed channel 5 is located.

[0040] Reference Figure 3 When the workpiece 9 is a rectangular structure, the feed channel 4 is a rectangular channel matching it, and two elastic sliding positioning members are provided. The telescopic directions of the pressing blocks 2 in the two elastic sliding positioning members are respectively toward the two adjacent side faces of the workpiece 9, and the angle between the two adjacent side faces is diagonal to the vertex angle where the knife feed channel 5 is located, so that the combined force of the two forces acting on the workpiece 9 is toward the vertex angle where the knife feed channel 5 is located.

[0041] Reference Figure 5 When the workpiece 9 is a pentagonal structure, the feed channel 4 is a pentagonal channel that matches it, and three elastic sliding positioning members are provided. The telescopic directions of the pressing blocks 2 in the three elastic sliding positioning members are respectively toward the three sides of the workpiece 9, and the combined force of the three acting on the workpiece 9 is toward the vertex angle where the knife feed channel 5 is located.

[0042] Reference Figure 6 When the workpiece 9 is a hexagonal structure, the feed channel 4 is a hexagonal channel that matches it, and two elastic sliding positioning members are provided. The telescopic directions of the pressing blocks 2 in the two elastic sliding positioning members are respectively toward the two sides of the workpiece 9, and the combined force of the two acting on the workpiece 9 is toward the top corner where the knife feed channel 5 is located.

[0043] Reference Figure 7 The chamfering equipment for completing chamfering at one time proposed in the present invention comprises a plurality of chamfering devices with allowable size floating as described above, all of which are arranged in sequence, and the feed channels 4 of each chamfering device with allowable size floating are connected in sequence to form a material transfer channel, when the workpiece 9 enters the material transfer channel, the tool feed channels 5 in each chamfering device with allowable size floating respectively correspond to different edges of the workpiece 9, and then the chamfering of multiple edges is completed at one time.

[0044] Furthermore, the number of chamfering devices that allow size fluctuation is N, where N is equal to the number of edges to be chamfered of the workpiece 9, and then the chamfering work of all the edges to be chamfered of the workpiece 9 is completed at one time.

[0045] As can be seen from the above, in the present invention, the feed channel 4 is used for allowing the workpiece 9 to pass through it, and the tool feed channel 5 is used for installing the chamfering tool or for the chamfering tool to feed from here; a plurality of elastic sliding positioning members are arranged in the main structure 1, so that the pressure block 2 in each elastic sliding positioning member applies pressure to the workpiece 9 entering the feed channel 4, so that the edge to be chamfered of the workpiece 9 is pressed into place, and because the pressure block 2 in the elastic sliding positioning member can be elastically retracted under the action of its elastic element 3, it can adapt to the floating size of the workpiece, ensure the precise positioning of the workpiece to be chamfered, and ensure the stability of the chamfering accuracy and good quality. In addition, by sequentially arranging a plurality of the chamfering devices and arranging them in sequence, the feed channels 4 thereof are sequentially connected to form a feed channel. When the workpiece 9 enters the feed channel, the tool feed channels 5 in each chamfering device that allows size floating respectively correspond to different edges of the workpiece 9, so that the workpiece 9 can complete all the chamfering to be chamfered at one time, which greatly improves the production efficiency.
