After the two welded decorative strips 100 are welded, burrs will be generated at the welding positions of each surface. The existing method is to remove the burrs manually, but the manual operation is labor-intensive and time-consuming, and the quality of manually trimmed products is unstable.

[0035] To this end, the present application embodiment provides a cutting jig for welding burr waste of automotive trim products, such as Figure 2 As shown, it specifically includes a mounting base 260 and a jig part integrated in the mounting base 260, and the jig part is used to cut the rough edges of the decorative strip products. Among them, the mounting base 260 is fixed on the frame 200, and the frame 200 is welded by square tubes. The bottom of the frame 200 is provided with universal wheels and support feet that can be adjusted up and down to facilitate the turnover and transportation of the jig. In order to facilitate the storage of decorative strip products, the frame 200 is provided with a plurality of storage parts 210, a part of the storage parts 210 is used to store the decorative strip products to be cut, and another part of the storage parts 210 is used to store the cut decorative strip products.

[0036] Furthermore, a collection box 240 for receiving cut waste is provided below the jig part, and the collection box 240 is fixed on the frame 200. The frame 200 is also provided with an enclosure 220 for covering the jig part, and a sensor 230 for sensing the approach of an object is provided on the enclosure 220. If the sensor 230 senses that an object is approaching the position of the jig part, the jig part stops operating. In order to facilitate the control of the jig part, a controller 250 for controlling the start and stop of the jig part is installed on the frame 200.

[0037] Specifically, Figure 3 and Figure 4As shown, the fixture part includes a first cutting structure 300, a second cutting structure 400 and a third cutting structure 500. The first cutting structure 300 and the third cutting structure 500 are each provided with two sets. The first cutting structure 300 includes a pressing member 310 and a first cutting member 320. The third cutting structure 500 includes a second cutting member 520 and a third cutting member 530. The two welded decorative strips 100 of the decorative strip product to be cut are respectively positioned in the two sets of the third cutting structure 50 0 is pre-tightened by the pressing member 310, wherein the two first cutting members 320 cooperate to cut the burrs on the upper surface 104 of the welding position of the decorative strip product, the two second cutting members 520 cooperate to cut the burrs on the lower surface 101 of the welding position of the decorative strip product, the two third cutting members 530 cooperate to cut the burrs on the inner surface 103 of the welding position of the decorative strip product, and the second cutting structure 400 is used to cut the burrs on the outer surface 102 of the welding position of the decorative strip product. It should be noted that the first cutting structure 300 and the third cutting structure 500 are adjusted and placed according to the welding angle of the welding decorative strip 100, so that the two sets of the third cutting structures 500 can accurately position the welding decorative strip 100, so that the first cutting structure 300 can press and position the welding decorative strip 100 on the third cutting structure 500.

[0038] When in use, the jig positions the two welded decorative strips 100 of the decorative strip product to be cut through two sets of third cutting structures 500. After positioning, the welded decorative strip 100 is fixed to the third cutting structure 500 through the clamping piece 310 of the first cutting structure 300, and then the two first cutting pieces 320 are used to cooperate to cut the burrs on the upper surface 104 of the decorative strip product at the welding position, the two second cutting pieces 520 are used to cooperate to cut the burrs on the lower surface 101 of the decorative strip product at the welding position, and the two third cutting pieces 530 are used to cooperate to cut the burrs on the inner surface 103 of the decorative strip product at the welding position, and finally the second cutting structure 400 is used to cut off the burrs on the outer surface 102 of the decorative strip product at the welding position. The jig of the present application can realize accurate cutting of the burrs at the welding position of the decorative strip product, without over-cutting and without missing any burrs, and the three cutting structures can operate simultaneously or individually. Compared with manual trimming of burrs one by one, the jig of the present application can greatly improve the cutting efficiency of burrs, and is not prone to missing or over-cutting, which can effectively improve the quality of products and reduce the chance of product scrapping.

[0039] In some embodiments, Figures 5 to 8As shown, the clamping member 310 includes a first cylinder and a clamping block 311. The first cylinder is fixed on the mounting base 260. The third cutting structure 500 also includes a positioning plate 510 fixed on the mounting base 260. The first cylinder is used to drive the clamping block 311 to move toward or away from the positioning plate 510. When the clamping block 311 and the positioning plate 510 are closed, a clamping cavity 600 is formed for limiting and clamping the welding trim 100 of the trim product. Among them, the pre-tightening surface of the pressing block 311 has a clamping groove with the same shape as the upper surface 104 of the welding decorative strip 100, and the positioning surface of the positioning plate 510 has a positioning groove with a similar shape to the lower surface 101 of the welding decorative strip 100, so that the positioning plate 510 can position the welding decorative strip 100. After the pressing block 311 and the positioning plate 510 are closed, the clamping groove and the positioning groove cooperate to form a clamping cavity 600 to clamp and limit the welding decorative strip 100, and it is not easy to cause deformation of the welding decorative strip 100.

[0040] Further, such as Fig.11 and Fig.12 As shown, the first cutting piece 320 is arranged on the pressing block 311, and the first cutting piece 320 includes a second cylinder and a first cutter 321. The first cutter 321 is arranged on the pressing block 311 to press against one side of the welding decorative strip 100, and the first cutter 321 can slide. Specifically, a slide groove 312 for the first cutter 321 to slide is provided on the pressing block 311, and the first cutter 321 is configured to fit the upper surface 104 of the welding decorative strip 100 positioned on the positioning plate 510. The second cylinder is used to drive the first cutter 321 to move toward the welding position of the decorative strip product. It should be noted that when the second cylinder drives the first cutter 321 to move toward the welding position of the decorative strip product, the first cutter 321 is in contact with the upper surface 104 of the welding decorative strip 100, so that the burrs protruding from the upper surface 104 can be removed.

[0041] Specifically, Fig. 9 As shown, when the first cutters 321 of the two first cutting pieces 320 move along the upper surface 104 of the welded decorative strip 100 and intersect at the welded position of the decorative strip product, the cutting edges of the two first cutters 321 abut against each other, so that the burrs protruding from the upper surface 104 of the welded decorative strip 100 can be removed. It should be noted that the two first cutters 321 can move at the same time, or one can move first and then the other, and the burrs can be removed as long as the two first cutters 321 are in an intersecting state.

[0042] In some embodiments, Fig.13 and Fig.14As shown, the second cutting piece 520 includes a third cylinder and a second cutter 521. The second cutter 521 is slidably disposed on the positioning plate 510 for contacting one side of the welding decorative strip 100. The second cutter 521 is configured to fit the lower surface 101 of the welding decorative strip 100 positioned on the positioning plate 510. The third cylinder is used to drive the second cutter 521 to move in the direction of the welding position of the decorative strip product. It should be noted that when the third cylinder drives the second cutter 521 to move in the direction of the welding position of the decorative strip product, the second cutter 521 fits the lower surface 101 of the welding decorative strip 100, so that the burrs protruding from the lower surface 101 can be removed.

[0043] Further, such as Fig.10 As shown, when the second cutters 521 of the two second cutting pieces 520 move along the lower surface 101 of the welded decorative strip 100 and intersect at the welded position of the decorative strip product, the cutting edges of the two second cutters 521 abut against each other, so that the burrs protruding from the lower surface 101 of the welded decorative strip 100 can be removed. It should be noted that the two second cutters 521 can move at the same time, or one can move first and then the other, and the burrs can be removed as long as the two second cutters 521 are in an intersecting state.

[0044] In some embodiments, the third cutting member 530 includes a fourth cylinder and a third cutter 531. The third cutter 531 is slidably disposed on the positioning plate 510. The third cutter 531 is configured to fit the inner surface 103 of the welded decorative strip 100 positioned on the positioning plate 510. The fourth cylinder is used to drive the third cutter 531 to move in the direction of the welded position of the decorative strip product. It should be noted that when the fourth cylinder drives the third cutter 531 to move in the direction of the welded position of the decorative strip product, the third cutter 531 fits the inner surface 103 of the welded decorative strip 100, so that the burrs protruding from the inner surface 103 can be removed.

[0045] Furthermore, when the third cutters 531 of the two third cutting pieces 530 move along the inner surface 103 of the welded decorative strip 100 and intersect at the welded position of the decorative strip product, the cutting edges of the two third cutters 531 abut against each other, so that the burrs protruding from the inner surface 103 of the welded decorative strip 100 can be removed. It should be noted that the two third cutters 531 can move at the same time, or one can move first and then the other, and the burrs can be removed as long as the two third cutters 531 are in an intersecting state.

[0046] In the embodiment of the present application, the mounting base 260 is vertically arranged, and the trim product placed on the third cutting structure 500 is positioned and limited by the positioning plate 510 and the third cutter 531. Since the trim product is made of two welded trim strips 100 welded at a certain angle, the mounting base 260 and the fixture part placed in the vertical direction can position the trim product without adding additional parts. Figure 1 As shown, because the inner surface is concave inward, when the lower surface 101 is in contact with the positioning plate 510, the third cutter 531 is inserted into the inner surface 103 for positioning and clamping. This avoids deformation of the cutting position and enables better positioning, effectively utilizing the existing structure, and is cleverly designed.

[0047] In some embodiments, Figure 7 and Figure 8 As shown, the second cutting structure 400 includes a fifth cylinder and two fourth cutters 411. The fifth cylinder is used to drive the two fourth cutters 411 to move toward each other, and when the two fourth cutters 411 intersect, the cutting edges of the fourth cutters 411 fit the border of the outer surfaces 102 of the two welded decorative strips 100. When the two fourth cutters 411 intersect, the fourth cutters 411 are flush with the border of the outer surfaces 102 of the two welded decorative strips 100, which can avoid over-cutting and can well remove the protruding burrs.

[0048] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
