[0033] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention.

[0034] Please see Figure 2 and Figure 3 A tool mark grinding machine 10 includes a machine base 100, a material transfer component 200, a material loading component 300, and a grinding component 400. The material transfer component 200 includes a vibrating plate 210 and a feeding track 220. The vibrating plate 210 is mounted on the machine base 100, and the feeding track 220 is connected to the discharge port of the vibrating plate 210. The material loading component 300 includes a material loading slide plate 310, a sliding drive component 320, and two clamping components 330. The material loading slide plate 310 is slidably mounted on the machine base 100, and the sliding drive component 320 is mounted on the machine base 100 and connected to the material loading slide plate 310. The material loading slide plate 310 has two material loading slots 311, and both clamping components 330 are provided with... On the machine base 100, and with two clamping parts 330 respectively located on both sides of the feeding track 220, the sliding drive 320 is used to drive the material loading slide 310 to slide so that one of the material loading slots 311 is aligned with one of the clamping parts 330, and the other material loading slot 311 is connected to the feeding track 220. The grinding assembly 400 includes a grinding drive 410 and a grinder 420. The grinding drive 410 is disposed on the machine base 100, and the grinder 420 is disposed on the grinding drive 410. The grinding drive 410 is used to drive the grinder 420 to approach one of the material loading slots so that the grinder 420 grinds the hardware parts 20 located in the material loading slot 311.

[0035] It should be noted that the material transfer assembly 200, the material carrier assembly 300, and the grinding assembly 400 are all installed on the machine base 100. The material transfer assembly 200 is used to discharge and transfer the hardware parts 20. The material carrier assembly 300 is used to connect with the material transfer assembly 200 so that a number of hardware parts 20 are transferred to the material carrier assembly 300. The grinding assembly 400 is used to perform grinding operations on the hardware parts 20 on the material carrier assembly 300.

[0036] Specifically, both the vibratory feeder 210 and the feeding track 220 are mounted on the machine base 100. The feeding track 220 is connected to the discharge port of the vibratory feeder 210. After the vibratory feeder 210 vibrates and discharges the hardware parts 20, they are then transferred to the feeding track 220. The loading slide plate 310 is slidably mounted on the machine base 100. For example, a slide rail is installed on the machine base 100, and the loading slide plate 310 is mounted on the slide rail, allowing the loading slide plate 310 to slide relative to the machine base 100. The sliding direction of the loading slide plate 310 is perpendicular to the feeding direction of the feeding track 220. The sliding drive component 320 is mounted on the machine base 100 and connected to the loading slide plate 310. The sliding drive component 320 drives the loading slide plate 310 to slide. In one embodiment, the sliding drive component 320 is a cylinder. Furthermore, the material-carrying slide plate 310 has two material-carrying slots 311, the extension direction of which is consistent with the feeding direction of the feeding track 220. When the sliding drive member 320 drives the material-carrying slide plate 310 to slide, the two material-carrying slots 311 can be connected to the feeding track 220 in turn. Two clamping members 330 are both mounted on the machine base 100, and the two clamping members 330 are located on both sides of the feeding track 220. When one of the material-carrying slots 311 is connected to the feeding track 220, the other material-carrying slot 311 will be aligned with one of the clamping members 330.

[0037] For ease of description, the two material loading slots 311 are defined as the first slot and the second slot, respectively. Similarly, the two corresponding clamping components 330 are defined as the first clamping component and the second clamping component, respectively. The sliding drive component 320 drives the material loading slide plate 310 to slide, so that the first slot and the second slot alternately connect with the feeding track 220. When the first slot is connected with the feeding track 220, the second slot will align with the second clamping component. In this way, the second clamping component clamps and fixes the hardware component 20 in the second slot, so that the grinding drive component 410 drives the grinder 420 to abut against each hardware component 20 in the second slot to perform a grinding operation on the hardware component 20. At the same time, the feeding track 220 will move the hardware component 20 into the first slot. After the hardware component 20 in the second slot has been ground, the second clamping component will push the hardware component 20 in the second slot to unload it, thereby emptying the second slot, and the first slot has also been filled. At this time, the sliding drive 320 drives the material-carrying slide plate 310 to slide, so that the second slot is connected with the empty material track 220, thereby refilling the second slot. Simultaneously, the first slot aligns with the first clamp, which clamps and secures the metal component 20 in the first slot. Then, the grinding drive 410 drives the grinder 420 to grind the metal component 20 in the first slot. After grinding the metal component 20 in the first slot is complete, the second slot is also filled with metal component 20. At this time, the first clamp pushes the metal component 20 in the first slot to unload it, thus emptying the first slot. Then, the sliding drive 320 drives the material-carrying slide plate 310, so that the first slot is connected with the feeding track 220 again, and the second slot aligns with the second clamp, entering a new grinding cycle. Thus, compared to traditional manual grinding operations, the tool-mark grinding machine 10 of this application achieves automatic feeding and grinding of the metal component 20, thereby effectively improving the grinding quality and efficiency of the metal component 20. Furthermore, by setting the sliding drive component 320 to drive the material loading slide plate 310 to slide, so that the two material loading troughs 311 can be loaded in turn, the waiting time of the grinder 420 can be reduced, effectively reducing the equipment waiting time and further improving the grinding efficiency.

[0038] Please see Figure 3 In one embodiment, the material transfer assembly 200 further includes a plurality of sensors 230, each sensor 230 being disposed on the feeding track 220 and each sensor 230 being disposed facing the feeding track 220.

[0039] It should be noted that, in order to prevent the metal parts 20 from getting stuck in the feeding track 220, multiple sensors 230 are installed on the feeding track 220, with each sensor 230 facing the feeding track 220, to detect the movement of the metal parts 20 within the feeding track 220. For example, the sensor 230 is a metal sensor used to detect whether the metal parts 20 are shifting. In one embodiment, three sensors 230 are provided, with a gap between them.

[0040] Please see Figure 3 In one embodiment, the material transfer assembly 200 further includes a vertical vibration 240, and the feeding track 220 is disposed on the vertical vibration 240.

[0041] It should be noted that in order to ensure that the hardware components 20 in the feeding track 220 can be smoothly transferred, a vertical vibrator 240 is installed, and the feeding track 220 is mounted on the vertical vibrator 240. The vertical vibrator 240 drives the feeding track 220 to vibrate, so that the hardware components 20 can be conveyed in one direction.

[0042] Please see Figure 3 and Figure 4 In one embodiment, the material transfer assembly 200 further includes a material blocking cylinder 250 and a material blocking rod 260. The material blocking cylinder 250 is disposed on the feeding track 220, and the material blocking rod 260 is disposed on the output shaft of the material blocking cylinder 250. The material blocking cylinder 250 is used to drive the material blocking rod 260 to move closer to or away from the feeding track 220.

[0043] It should be noted that when the hardware component 20 in the feeding track 220 is full, in order to prevent the hardware component 20 from continuing to be fed forward in the feeding track 220 and causing compression, a baffle cylinder 250 is installed to drive the baffle rod 260 to extend into the feeding track 220. The baffle rod 260 is used to hold and limit the hardware component 20 in the feeding track 220, preventing the hardware component 20 from continuing to move forward.

[0044] Please see Figure 4 In one embodiment, the material transfer assembly 200 further includes a limiting block 270, which is disposed on the blocking cylinder 250 and is used to abut against the output shaft of the blocking cylinder 250.

[0045] It should be noted that, in order to prevent the material stop bar 260 from scratching the hardware components 20 inside the feeding track 20 due to excessive thrust when it extends into the feeding track 220, a limiting block 270 is installed to limit the output shaft of the material stop cylinder 250 by pressing against it.

[0046] Please see Figure 2In one embodiment, the grinding drive 410 includes a transverse module 411, a lifting module 412, and a mounting plate 413. The transverse module 411 is disposed on the machine base 100, the lifting module 412 is disposed on the transverse module 411, the mounting plate 413 is disposed on the lifting module 412, and the grinder 420 is disposed on the mounting plate 413.

[0047] It should be noted that the transverse module 411 is mounted on the machine base 100, and the lifting module 412 is mounted on the transverse module 411. The mounting plate 413 is mounted on the lifting module 412. The transverse module 411 is used to drive the mounting plate 413 to move laterally. The lifting module 412 is used to drive the mounting plate 413 to move vertically. For example, both the transverse module 411 and the lifting module 412 are motor-driven lead screw structures. Thus, by mounting the grinder 420 on the mounting plate 413, the grinder 420 can be driven to perform grinding operations on the hardware components 20 in the two material loading tanks 311.

[0048] In one embodiment, the grinder 420 is an air grinding head. It should be noted that the air grinding head is a grinding structure driven by air pressure, thus, the air grinding head can effectively remove the tool marks on the surface of the hardware component 20.

[0049] Please see Figure 5 In one embodiment, the grinding assembly 400 further includes a swing plate 430 and a swing cylinder 440. The swing cylinder 440 is disposed on the mounting plate 413, the swing plate 430 is rotatably disposed on the mounting plate 413, and the swing plate 430 is connected to the output shaft of the swing cylinder 440. The grinder 420 is disposed on the swing plate 430. The swing cylinder 440 is used to drive the swing plate 430 to tilt, so that the grinder 420 tilts.

[0050] It should be noted that, in order to improve the polishing effect of the grinder 420 on the hardware component 20, a swing plate 430 is installed on the mounting plate 413. The swing plate 430 is connected to the mounting plate 413 by a pin, allowing the swing plate 430 to swing relative to the mounting plate 413. The output shaft of the swing cylinder 440 is connected to the swing plate 430, and the swing cylinder 440 drives the swing plate 430 to rotate, thereby enabling the grinder 420 to perform grinding operations on the hardware component 20 from multiple angles, improving the polishing effect on the hardware component 20.

[0051] Further, please refer to Figure 6 In one embodiment, the grinder 420 includes a grinding motor 421, a grinding belt 422, and a pressing block 423. The pressing block 423 is disposed on the mounting plate 413, the grinding motor 421 is disposed on the mounting plate 413, the grinding belt 422 is sleeved on the pressing block 423, and the grinding belt 422 is connected to the output shaft of the grinding motor 421. The grinding motor 421 is used to drive the grinding belt 422 to rotate continuously.

[0052] It should be noted that, in this embodiment, the grinding motor 421 is mounted on the mounting plate 413, the pressing block 423 is mounted on the mounting plate 413, the grinding belt 422 is sleeved on the pressing block 423, and the grinding belt 422 is connected to the output shaft of the grinding motor 421, so that the grinding motor 421 drives the grinding belt 422 to rotate continuously. In this way, under the pressing action of the bottom wall of the pressing block 423, the rotating grinding belt 422 can perform a grinding operation on the hardware parts 20 located in the two material loading grooves 311.

[0053] Please see Figure 3 and Figure 7 In one embodiment, the material loading slide plate 310 includes a slide base 312, a material loading plate 313 and two inserts 314. The slide base 312 is slidably disposed on the machine base 100, the material loading plate 313 is disposed on the slide base 312, and the two inserts 314 are slidably disposed on the material loading plate 313. The two material loading grooves 311 are respectively located on the two inserts 314.

[0054] It should be noted that the slide block 312 is slidably mounted on the machine base 100. For example, the slide block 312 is mounted on the machine base 100 via a slide rail, allowing the slide block 312 to slide relative to the machine base 100. The material carrier plate 313 is mounted on the slide block 312, and both inserts 314 are slidably mounted on the material carrier plate 313. The two material slots 311 are located one-to-one on the two inserts 314. The sliding direction of the inserts 314 on the material carrier plate 313 is perpendicular to the sliding direction of the slide block 312 on the machine base 100. Thus, when it is necessary to grind hardware parts 20 of different sizes or shapes, only the inserts 314 need to be replaced, thereby improving the compatibility of the tool mark grinding machine 10.

[0055] Please see Figure 7 In one embodiment, a T-slot is provided on the material carrier plate 313, and the cross-section of the insert 314 is set as a T-shaped structure, with the insert 314 slidably disposed in the T-slot. It should be noted that the T-shaped structure can improve the stability of the insert 314, so that the hardware component 20 can be accurately transferred from the feeding track 220 to the material carrier groove 311 of the insert 314.

[0056] Please see Figure 7 and Figure 8 In one embodiment, the clamping component 330 includes a top-pressing cylinder 331, a top rod 332, a lifting cylinder 333, and a baffle 334. The top-pressing cylinder 331 is mounted on the machine base 100, the top rod 332 is mounted on the output shaft of the top-pressing cylinder 331, and the top rod 332 is aligned with the loading trough 311. The lifting cylinder 333 is mounted on the machine base 100, and the baffle 334 is mounted on the output shaft of the lifting cylinder 333. The baffle 334 and the top rod 332 are located at the two ends of the loading trough 311, respectively.

[0057] It should be noted that the lifting cylinder 333 is used to drive the baffle 334 to move up and down. When the baffle 334 rises, it will block one end of the material loading groove 311. The pressing cylinder 331 is used to drive the push rod 332 to slide closer to or away from the material loading groove 311. When the push rod 332 slides closer to the material loading groove 311, it can make the push rod 332 and the baffle 334 jointly clamp the hardware component 20 located in the material loading groove 311. After the hardware component 20 is polished, the lifting cylinder 333 drives the baffle 334 to descend, and then the pressing cylinder 331 drives the push rod 332 to move, so that the push rod 332 pushes the hardware component 20 in the material loading groove 311 out of the material.

[0058] Please see Figure 7 and Figure 8 In one embodiment, the material loading slide plate 310 is also provided with two magnetic holes 315, which are located below the two material loading grooves 311 respectively. The clamping component 330 also includes a magnetic rod 335, which is disposed on the output shaft of the top pressure cylinder 331 and is located below the top rod 332 so that the magnetic rod 335 is aligned with the magnetic hole 315.

[0059] It should be noted that, in order to further improve the stability of the hardware components 20 during grinding, a magnetic hole 315 is provided below the material loading groove 311, and a magnetic rod 335 is installed on the output shaft of the top pressure cylinder 331. When the top pressure cylinder 331 drives the top rod 332 to approach the material loading groove 311, so that the top rod 332 pushes and clamps the hardware components, the magnetic rod 335 passes into the magnetic hole 315, so that the magnetic rod 335 is located below the material loading groove 311, and the magnetic rod 335 adsorbs and fixes each hardware component 20 in the material loading groove 311.

[0060] Further, please refer to Figures 7 to 9 In one embodiment, the material loading assembly 300 further includes a limiting plate 340, which is disposed on the machine base 100 and adjacent to the material loading slide plate 310. The limiting plate 340 is provided with a clearance groove 341 and a negative pressure hole 342. The clearance groove 341 is aligned with the material loading groove 311, and the negative pressure hole 342 is connected to the clearance groove 341.

[0061] It should be noted that, in order to improve the stability of the push rod 332 when pressing the hardware component 20, a limiting plate 340 is also installed on the machine base 100. The limiting plate 340 has a clearance groove 341 and a negative pressure hole 342. The clearance groove 341 is aligned with the material loading groove 311, so that the push rod 332 passes through the clearance groove 341 and then presses and fixes the hardware component 20 in the material loading groove 311. The negative pressure hole 342 is connected to the clearance groove 341. The negative pressure hole 342 is used to connect with an external vacuum generator. In this way, the vacuum generator creates a negative pressure in the negative pressure hole 342, which can adsorb and fix the push rod 332 located in the clearance groove 341, so that the push rod 332 is attached to the bottom wall of the clearance groove 341. This improves the pressing stability of the push rod 332 on the hardware component 20 and avoids the structural instability problem caused by the push rod 332 being too long and narrow.

[0062] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
