Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, specifically a grinding device for hardware processing. Background Technology

[0002] Hardware processing involves using lathes, milling machines, drilling machines, polishing machines, and other machinery to process raw materials into various parts according to customer drawings or samples, such as screws, motor shafts, model car parts, fishing tackle accessories, speaker casings, and power bank casings.

[0003] During the processing of hardware products, it is often necessary to polish the hardware parts to remove burrs and scratches.

[0004] Under current technological conditions, grinding devices used in metal processing can typically only perform end-face grinding and polishing operations on disc-shaped parts. Due to the lack of adaptability to parts of different sizes and the inability to process multiple parts simultaneously, such equipment exhibits significant inefficiency in practical applications, leading to longer overall processing cycles and limited production capacity. The single-function design also restricts the versatility and flexibility of the device in complex production environments.

[0005] Therefore, we propose a grinding device for hardware processing to solve the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] like Figure 1-4 As shown in the figure, a metal processing grinding device according to one embodiment of the present invention includes a processing machine table 1, a grinding device 2 is provided at the top of the processing machine table 1, a clamping structure 3 is provided inside the processing machine table 1, and a control panel 4 is provided on the front side of the processing machine table 1.

[0030] The clamping structure 3 includes a mounting plate 301. An external gear ring 302 is rotatably connected to the top of the mounting plate 301, and a drive motor 303 and a fixing disk 306 are fixedly mounted thereon. The fixing disk 306 is located inside the external gear ring 302, and a connecting disk 307 is provided above the fixing disk 306.

[0031] The output shaft of the drive motor 303 is fixedly mounted with a gear 304, which meshes with the external gear ring 302 for transmission. An abutment plate 305 is installed on the inner side of the external gear ring 302.

[0032] like Figure 2 As shown, in some embodiments, the processing machine base 1 includes a processing base 101, the processing base 101 has an inner groove 102, and the bottom end of the mounting plate 301 is movably engaged with the inner groove 102.

[0033] Specifically, by movably engaging the mounting plate 301 into the embedded groove 102, the clamping structure 3 and the processing table 1 can be flexibly assembled and disassembled, which facilitates the subsequent maintenance and replacement of the clamping structure 3 and improves the ease of use and maintainability of the device.

[0034] like Figure 2 As shown, in some embodiments, a placement plate 103 is movably engaged at the opening of the recessed groove 102, and the interior of the placement plate 103 has a notch adapted to the connecting plate 307.

[0035] Specifically, the placement plate 103 prevents debris generated during the grinding process from falling into the inner groove 102 and affecting the normal operation of the clamping structure 3. At the same time, the notch design facilitates the connection and operation of the connecting plate 307 with the outside, ensuring the overall stability and reliability of the device.

[0036] like Figure 4 As shown, in some embodiments, a connecting rod 308 is fixedly installed at the center of the fixed plate 306, the top end of the connecting rod 308 is fixedly connected to the bottom end of the connecting plate 307, and a placement plate 314 is fixedly installed at the center of the connecting plate 307, with an anti-slip pad provided at the top end of the placement plate 314.

[0037] Specifically, the connecting rod 308 serves to securely connect the fixed plate 306 and the connecting plate 307, making the entire clamping structure 3 more stable.

[0038] The placement tray 314 is used to place the disc-shaped parts to be polished. The anti-slip pad can increase the friction between the parts and the placement tray 314, preventing the parts from sliding during the polishing process and affecting the polishing effect.

[0039] like Figure 4 As shown, in some embodiments, the top of the fixed disk 306 is provided with eight slide rails 309, and the slide rails 309 are provided with push blocks 310 inside. The eight push blocks 310 are arranged in a circular array on the top of the fixed disk 306, and the outer wall of the push block 310 overlaps with the slope of the abutment inclined plate 305.

[0040] Specifically, the eight circularly arranged push blocks 310 can simultaneously converge towards the center or move outward by resisting the inclined plate 305 under external force. This design allows the device to adaptively clamp disc-shaped parts of different sizes, achieving fast and precise positioning and fixation without manual adjustment.

[0041] like Figure 4 As shown, in some embodiments, a damping spring 311 is provided inside the slide rail 309, and the other end of the damping spring 311 is connected to the bottom end of the push block 310.

[0042] Specifically, the damping spring 311 can provide effective shock absorption and cushioning when the push block 310 reciprocates.

[0043] When the push block 310 begins to move under external force, the damping spring 311 absorbs part of the kinetic energy through its elastic deformation, thereby slowing down the movement speed of the push block 310. This effectively avoids excessive instantaneous clamping force caused by the push block 310 moving too fast, and prevents squeezing damage or structural damage to the clamped precision parts.

[0044] Furthermore, when the abutting ramp 305 stops pushing the pusher block 310 and disengages, the damping spring 311 will gradually rebound due to its restoring force, guiding the pusher block 310 to return to its initial position smoothly and slowly.

[0045] like Figure 4 As shown, in some embodiments, the connecting disk 307 has a through-hole 312 inside, and a clamping strip 313 is provided inside the through-hole 312. The top end of the pushing block 310 extends to the inside of the through-hole 312 and is fixedly connected to the bottom end of the clamping strip 313.

[0046] Specifically, as the pusher block 310 moves along a predetermined trajectory, it drives the clamping strip 313 to slide smoothly and stably inside the through-hole 312.

[0047] Under the action of the push block 310, each clamping bar 313 can move synchronously and in a coordinated manner toward the center or outward, thereby achieving reliable clamping or smooth release of the target part.

[0048] When in use, first place the disc-shaped hardware on the placement plate 314, start the drive motor 303 through the control panel 4, the output shaft of the drive motor 303 drives the gear 304 to rotate, the gear 304 meshes with the external gear ring 302 to drive the external gear ring 302 to start rotating.

[0049] The abutting inclined plate 305 installed on the inner side of the outer toothed ring 302 rotates accordingly, and its slope overlaps with the outer wall of the push block 310. During the rotation, the abutting inclined plate 305 will push the push block 310 to move along the slide rail 309.

[0050] Because the slide rail 309 is equipped with a damping spring 311, the damping spring 311 can provide effective shock absorption and buffering when the push block 310 moves back and forth, so as to avoid the push block 310 moving too fast and generating too large instantaneous clamping force.

[0051] When the push block 310 moves, it will cause the clamping strip 313 to slide inside the through opening 312. Multiple clamping strips 313 move towards the center at the same time, and perform adaptive clamping according to the different sizes of disc-shaped parts, so as to firmly clamp the disc-shaped hardware on the placement plate 314.

[0052] Then, the grinding equipment 2 is controlled by the control panel 4 to perform end face grinding and polishing operations on the clamped disc-shaped hardware.

[0053] After grinding is completed, the drive motor 303 is started again to make the external gear ring 302 rotate in the opposite direction, causing the contact inclined plate 305 to gradually move away from the push block 310;

[0054] At this time, the push block 310 will gradually rebound due to its restoring force, guiding the push block 310 to return to its initial position smoothly and slowly, thereby driving the clamping bar 313 to move outward, releasing the polished disc-shaped hardware, and removing it from the placement plate 314.

[0055] In summary, the drive motor 303 drives the gear 304 to rotate, and the gear 304 meshes with the external gear ring 302 to drive the external gear ring 302 to rotate. The inner side of the external gear ring 302 rotates accordingly, and the slope of the contact plate 305 overlaps with the outer wall of the push block 310. During the rotation, the contact plate 305 pushes the push block 310 to move along the slide rail 309. When the push block 310 moves, it drives the clamping bars 313 to move. Multiple clamping bars 313 move simultaneously towards the center or outward, so as to adaptively clamp disc-shaped parts of different sizes, realize the end face grinding and polishing operation of parts of different sizes and specifications, and improve the adaptability of the device to parts of different sizes.

[0056] It should be noted that the specific models and specifications of the grinding equipment 2, drive motor 303, and control panel 4 in the grinding device for hardware processing need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0057] Furthermore, the power supply and operating principle of the grinding equipment 2, drive motor 303, and control panel 4 in the metal processing grinding device are clear to those skilled in the art, and will not be described in detail here.

[0058] Furthermore, the working principles and wiring methods of the grinding equipment 2, drive motor 303, and control panel 4 in the grinding device for hardware processing are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0059] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
