[0020] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0021] like Figures 1 to 5 The diagram shown is a structural schematic of a high-precision terminal trimming device provided by this utility model. The high-precision terminal trimming device includes a base 10, a conveying device 20 disposed on the base 10, and a trimming device 30 disposed on the base 10 and located on one side of the conveying device 20. It is conceivable that the high-precision terminal trimming device also includes other functional structures, such as fixing bolts, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0022] The base 10 includes a base body 11 and a waste hole 12 disposed on the base body 11. The base body 11 is used to be fixedly mounted on a flat surface such as a workbench, and the waste hole 12 is used to discharge the trimmed waste. The base body 11 is provided with a plurality of insertion holes 13, which are used to insert and fix the conveying device 20 and the trimming device 30.

[0023] The conveying device 20 includes a conveyor frame 21, a conveyor belt assembly 22 disposed in the middle region of the conveyor frame 21, a guide rail 23 disposed on one side of the conveyor belt assembly 22, a guide groove 24 disposed on the side of the conveyor belt assembly 22 facing away from the guide rail 23, a conveyor platform 25 clamped on the conveyor belt assembly 22 and the guide rail 23, a steering rod 26 rotatably disposed on the conveyor platform 25 corresponding to the position of the guide groove 24, a feeding disc 27 disposed on the end of the steering rod 26 away from the conveyor platform 25, a connecting plate 28 fixedly disposed on the steering rod 26, and a guide wheel 29 rotatably connected to the other end of the connecting plate 28 and accommodated in the guide groove 24.

[0024] The conveyor frame 21 is inserted and fixed in the insertion hole 13. The conveyor frame 21 includes a platform 211 and a countersunk hole 212 located at the end of the platform 211 away from the trimming device 30. The platform 211 is used to mount the conveyor belt assembly 22 and the guide rail 23. The countersunk hole 212 is used to cooperate with the conveyor belt assembly 22, which will be described below in conjunction with the conveyor belt assembly 22.

[0025] The conveyor belt assembly 22 includes a drive motor 221 disposed on the end face of the countersunk hole 212 facing the base 10, a drive gear 222 disposed in the countersunk hole 212 and connected to the output end of the drive motor 221, a driven gear 223 disposed on the end of the platform 211 away from the drive gear 223, and a conveyor belt 224 sleeved on the drive gear 222 and the driven gear 223.

[0026] The output end of the drive motor 221 passes through the countersunk hole 212. The driving gear 222 is fixedly connected to the output end of the drive motor 221, so that the drive motor 221 drives the driving gear 222 to rotate, which in turn drives the driven gear 223 to rotate through the conveyor belt 224, thus forming a complete belt drive system. The center points of both the driving gear 222 and the driven gear 223 are located on the central axis along the length of the platform 211.

[0027] The guide rail 23 is disposed on the platform 211 and is parallel to the central axis of the platform 211 along its length, thereby cooperating with the conveyor belt assembly 22 to guide the conveyor belt 25 to slide.

[0028] The guide groove 24 is located on the side of the platform 211 away from the guide rail 23. (See also...) Figure 4 The guide groove 24 includes a long groove 241 and a short groove 242 that is vertically disposed on the long groove 241 near the end of the drive gear 222.

[0029] The long groove 241 and the short groove 242 have an arc-shaped transition, which can better guide the flow.

[0030] The conveyor table 25 includes a conveyor table body 251 and two sliders 252 disposed on the end face of the conveyor table body 251 facing the table surface 211. The two sliders 252 are respectively clamped on the conveyor belt 25 and the guide rail 23. When the drive motor 221 drives the drive gear 222 to rotate, the conveyor belt 25 drives the sliders 252, thereby driving the conveyor table 25 to reciprocate along the guide rail 23.

[0031] One end of the steering rod 26 is movably mounted on the conveyor table 25 and fixedly connected to the feeding tray 27, while the other end is provided with the connecting plate 28. The steering rod 26 is fixedly connected to both the feeding tray 27 and the connecting plate 28, and the central axis of the steering rod 26 is parallel to the longitudinal axis of the feeding tray 27. The feeding tray 27 is used to feed and deliver materials to the trimming device 30 for trimming. The feeding tray 27 includes a feeding tray body 271, two stops 272 disposed at one end of the feeding tray body 271, and an opening 273 disposed at the other end of the feeding tray body 271.

[0032] The guide wheel 29 is rotatably connected to the other end of the connecting plate 28 and is housed in the guide groove 24. When the conveyor table 25 slides along the guide rail 23, the guide wheel 29 slides along the guide groove 24. When the guide wheel 29 is in the long groove 241, the opening 273 faces the trimming device 30. As the guide wheel 29 gradually enters the short groove 242 along the long groove 241, the connecting plate 28 gradually rotates 90 degrees along the steering rod 26. Since the connecting plate 28 and the steering rod 26 are fixedly connected, and the feeding tray 27 and the steering rod 26 are also fixedly connected, the feeding tray 27 can be driven to rotate 90 degrees in the same direction to facilitate subsequent material loading.

[0033] The trimming device 30 includes a trimming seat 31 corresponding to the waste hole 12, a bracket 32 ​​on the base 10, a telescopic cylinder 33 on the end face of the bracket 32 ​​away from the base 10, a coupling 34 with one end connected to the output end of the telescopic cylinder 33, a top plate 35 on the other end of the coupling 34, and two pairs of trimming structures 36 spaced apart on the end face of the top plate 35 facing the trimming seat 31.

[0034] The trimming seat 31 includes a trimming seat body 311, a material discharge hole 312 disposed on the trimming seat body 311, and a top side 313 disposed on the side of the material discharge hole 312 away from the conveying device 25. The material discharge hole 312 corresponds to the end of the opening 273.

[0035] The trimming seat body 311 is trapezoidal, with an inclined end facing the conveying device 25 for guiding purposes. The discharge hole 312 is connected to the waste hole 12 and has the same size, thus guiding the trimmed waste into the waste hole 12 for discharge. The top side 313 assists in material positioning, improving trimming efficiency.

[0036] The bracket 32 ​​is inserted into the insertion hole 13 for mounting the telescopic cylinder 33, the connecting shaft 34, the abutment plate 35, and the trimming structure 36. The end of the trimming structure 36 is accommodated in the material discharge hole 312. The telescopic cylinder 33 drives the connecting shaft 34 to drive the abutment plate 35 to perform vertical reciprocating motion along its own axis, thereby trimming the material through the trimming structure 36.

[0037] In use, when the conveyor belt assembly 22 drives the conveyor table 25 to slide along the guide rail 23 away from the trimming device 30, the guide wheel 29 slides along the guide groove 24. When the guide wheel 29 is in the long groove 241, the opening 273 faces the trimming device 30. As the guide wheel 29 gradually enters the short groove 242 along the long groove 241, the connecting plate 28 gradually rotates 90 degrees along the steering rod 26. Since the connecting plate 28 and the steering rod 26 are fixedly connected, and the feeding disc 27 and the steering rod 26 are also fixedly connected, the feeding disc 27 can be driven to rotate 90 degrees in the same direction, thereby completing the feeding. Next, the conveyor belt assembly 22 drives the conveyor table 25 to move toward the trimming device 30. At this time, the guide wheel 29 contacts the side wall of the short trough 242. As the conveyor table 25 continues to move, the connecting plate 28 gradually becomes parallel to the long trough 241. At this time, the opening 273 is exactly facing the trimming device 30, thus enabling the feeding and trimming to be completed.

[0038] Compared with the prior art, the high-precision terminal trimming device provided by this utility model provides a guide groove 24 on the conveyor frame 21, a steering rod 26 on the conveyor table 25, and a feeding tray 27 and a connecting plate 28 fixedly mounted at both ends of the steering rod 26. A guide wheel 29 is provided at the other end of the connecting plate 28. Through the cooperation of the guide wheel 29 and the guide groove 24, the connecting plate 28 can rotate 90 degrees when entering and leaving the short groove 242, which facilitates trimming and feeding, and the angle of rotation is fixed each time to avoid angular errors. A stop block 272 is provided on the feeding tray body 271 to assist in the positioning of the plate, and a top side 313 is provided on the trimming seat body 311 to improve the accuracy during trimming, reduce the defect rate, and improve processing efficiency.
