Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, and specifically, to a hardware processing and grinding device. Background Technique

[0002] Hardware fittings refer to machine parts or components made of hardware, as well as some small hardware products. Common hardware fittings include pulleys, casters, joints, spray nozzles, etc. Hardware fittings can be used alone or as assisting tools. When processing hardware fittings, a hardware processing and grinding device is required.

[0003] When the grinding device in the prior art grinds hardware parts, it cannot effectively adjust the angular position of the hardware parts. When grinding hardware parts, sometimes it is necessary to grind not only one surface of the hardware parts, but also other surfaces of the hardware parts. However, after grinding one surface of the hardware parts by the grinding device in the prior art, the hardware parts need to be disassembled and fixed again to effectively grind other surfaces of the hardware parts. This will result in a relatively low grinding efficiency of the hardware parts, and at the same time increase the workload of the staff. Moreover, when grinding hardware parts, a grinding disc is generally required. However, after long-term use, the grinding disc will inevitably be worn. The grinding device in the prior art cannot conveniently disassemble and replace the grinding disc, which will affect the grinding effect and efficiency after grinding the hardware parts.

[0004] Comparing with the Chinese patent with the publication number of CN219337270U, the utility model discloses a grinding device for processing hardware parts, including a base. A positioning groove is opened at the top of the base. Limiting wheels are fixedly connected to both sides of the inner cavity of the positioning groove. A positioning block is movably connected to the opposite sides of the limiting wheels. A table board is fixedly connected to the top of the positioning block. The utility model installs and supports the table board and the vertical board by setting the base, places the hardware parts by setting the table board, adjusts the position of the table board by setting the positioning groove, limiting wheels and positioning block, enables the cross board to move up and down by setting the vertical board, groove, slide bar, first spring and slider, fixes the driving mechanism by setting the cross board, and positions and fixes the hardware parts by setting the positioning mechanism to prevent the hardware parts from shifting during grinding, thereby improving the efficiency of the hardware parts grinding work.

[0005] The above solution can very conveniently position and fix the hardware parts, thereby preventing the hardware parts from shifting during the grinding process. However, the above solution still cannot effectively adjust the angle of the hardware parts. When it is necessary to grind other surfaces of the hardware parts, the staff still needs to manually flip and fix the hardware parts, which is time-consuming and laborious. Moreover, the above solution cannot conveniently disassemble and replace the grinding disc, and fails to solve the problems raised in the above background technology.

[0006] Therefore, those skilled in the art provide a hardware processing and grinding device to solve the problems raised in the above background technology. Utility Model Content

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1 - Figure 8 As shown in the figure, this embodiment provides a hardware processing and grinding device, including a processing table 1, and further including:

[0032] A moving plate 2, symmetrically arranged above the processing table 1. Above the moving plate 2, there is a fixed plate 3. An installation groove for installing a rotating rod 4 is penetrated inside the fixed plate 3. One end of the rotating rod 4 is fixedly connected to a knob 5, and the other end of the rotating rod 4 is fixedly connected to a clamping plate 6. A hardware part body 7 is arranged between the two clamping plates 6;

[0033] A fixing component, symmetrically arranged at the bottom of the processing table 1 and used for fixedly clamping the hardware part body 7;

[0034] An angle adjustment component, respectively arranged on the upper surfaces of the two fixed plates 3 and used for adjusting the angle of the hardware part body 7;

[0035] The electric hydraulic rods 9 are symmetrically arranged on the upper surface of the processing table 1. The telescopic ends of the two electric hydraulic rods 9 are fixedly connected with a top plate 10. A bottom plate 12 is arranged below the top plate 10. A first motor 13 is fixedly connected to the upper surface of the bottom plate 12. The output shaft of the first motor 13 is fixedly connected with a driving rod 14 through a coupling. The bottom end of the driving rod 14 is fixedly connected with a mounting disc 15. A connecting sleeve 16 is sleeved outside the mounting disc 15. The bottom of the connecting sleeve 16 is fixedly connected with a grinding disc 17;

[0036] An installation component is arranged inside the mounting disc 15 and is used for installing and disassembling between the mounting disc 15 and the connecting sleeve 16.

[0037] The above working principle: When the hardware part body 7 needs to be polished, just place the hardware part body 7 between the two clamping plates 6 first. At this time, the fixing component starts to operate. The fixing component can effectively drive the moving plate 2 to move synchronously. The moving plate 2 then drives the fixing plate 3 and the clamping plates 6 to move synchronously. When the clamping plates 6 abut against the outside of the hardware part body 7, the hardware part body 7 can be effectively fixed and clamped by the clamping plates 6. After the hardware part body 7 is fixed, the electric hydraulic rod 9 starts to operate. At this time, the electric hydraulic rod 9 will drive the top plate 10 to move synchronously. The top plate 10 then drives the bottom plate 12 to move synchronously. While the electric hydraulic rod 9 is operating, the first motor 13 also starts to operate synchronously. At this time, the first motor 13 will drive the driving rod 14 to rotate synchronously. The driving rod 14 then drives the grinding disc 17 to rotate synchronously. When the grinding disc 17 contacts the outer surface of the hardware part body 7, the hardware part body 7 can be effectively polished. When the other surfaces of the hardware part body 7 need to be polished, just through the angle adjustment component, the hardware part body 7 can be conveniently flipped, so that the grinding disc 17 can effectively polish the other surfaces of the hardware part body 7 without manual flipping of the hardware part body 7 by the staff, effectively improving the polishing efficiency of the hardware part body 7 and reducing the work burden of the staff. When the grinding disc 17 needs to be disassembled and replaced, just through the installation component, the mounting disc 15 and the connecting sleeve 16 can be conveniently disassembled and assembled, so that the grinding disc 17 can be conveniently disassembled and assembled, saving time and effort.

[0038] In order to effectively fix and clamp the hardware part body 7, the fixing component includes adjusting plates 18 symmetrically arranged at the bottom of the processing table 1. The inner side walls of the two adjusting plates 18 are both rotatably connected with bidirectional threaded rods 20. The other ends of the two bidirectional threaded rods 20 both extend to the outside of the adjusting plates 18 and are fixedly connected with limit discs 21. A second motor 19 is fixedly connected to the outside of one of the adjusting plates 18. The output shaft of the second motor 19 is fixedly connected to one end of one of the bidirectional threaded rods 20 through a coupling. The two bidirectional threaded rods 20 are connected by a synchronous belt 22 and pulley drive. Threaded blocks 23 are symmetrically arranged on the outside of the two bidirectional threaded rods 20. Guide grooves for the threaded blocks 23 to move are opened on the contact surfaces between the two adjusting plates 18 and the processing table 1. The upper surfaces of every two threaded blocks 23 are respectively fixedly connected to the bottoms of the two moving plates 2. When it is necessary to fix the hardware part body 7, just place the hardware part body 7 between the two clamping plates 6 first. At this time, the second motor 19 starts to operate. The second motor 19 will drive one of the bidirectional threaded rods 20 to rotate synchronously. Since the two bidirectional threaded rods 20 are connected by a synchronous belt 22 and pulley drive, the two bidirectional threaded rods 20 will rotate synchronously at this time. The threaded blocks 23 will move synchronously on the outside of the bidirectional threaded rods 20, driving the moving plates 2 to move synchronously. The moving plates 2 will then drive the fixing plates 3 to move synchronously. The fixing plates 3 will then drive the clamping plates 6 to move synchronously. When the opposite sides of the two clamping plates 6 both abut against the outside of the hardware part body 7, the hardware part body 7 can be effectively fixed and clamped.

[0039] Considering that when processing the hardware part body 7, it is necessary to adjust the height position of the clamping plate 6 according to the specifications of the hardware part body 7 to prevent the hardware part body 7 from being too large and affecting the flipping effect of the hardware part body 7. Therefore, mounting sleeves 24 are symmetrically arranged on the upper surfaces of the two moving plates 2. Moving rods 25 are arranged inside the multiple mounting sleeves 24. The multiple moving rods 25 are fixedly connected to the mounting sleeves 24 through bolts. The tops of every two moving rods 25 are respectively fixedly connected to the bottoms of the two fixing plates 3. When it is necessary to adjust the height position of the clamping plate 6, just unscrew the bolts first, and then pull the moving rods 25 inside the mounting sleeves 24. When the moving rods 25 drive the fixing plates 3 to move to the required height position, fix the moving rods 25 and the mounting sleeves 24 through bolts. At this time, the height positions of the fixing plates 3 and the clamping plates 6 can be effectively adjusted, thus preventing the hardware part body 7 from being too large and affecting the angle adjustment of the hardware part body 7.

[0040] In order to effectively adjust the angular position of the hardware part body 7, so as to facilitate the grinding disc 17 to grind other surfaces of the hardware part body 7, the angle adjustment assembly includes connecting blocks 29 respectively arranged on the upper surfaces of the two fixing plates 3. The upper surfaces of the two connecting blocks 29 are fixedly connected with fixed sleeves 30. A fixed rod 31 is arranged inside the fixed sleeve 30. One end of the fixed rod 31 extends to the outside of the fixed sleeve 30 and is fixedly connected with a pull plate. A contact disc 32 is fixedly connected to the outside of the fixed rod 31. A contact spring 33 is sleeved on the outside of the fixed rod 31. The contact spring 33 abuts between the contact disc 32 and the fixed sleeve 30. Rotating discs 8 are fixedly connected to the outside of the two rotating rods 4. Guide grooves for the movement of the fixed rod 31 are annularly formed inside the two rotating discs 8. When it is necessary to turn over the hardware part body 7, only need to pull the pull plate first. At this time, the pull plate will drive the fixed rod 31 to move synchronously. The fixed rod 31 will then drive the contact disc 32 to move synchronously. During the movement of the contact disc 32, the contact spring 33 will be compressed. When the fixed rod 31 disengages from the guide groove inside the rotating disc 8, turn the knob 5. At this time, the knob 5 will drive the rotating rod 4 to rotate synchronously. The rotating rod 4 will then drive the rotating disc 8 and the clamping plate 6 to rotate synchronously. The clamping plate 6 will then drive the hardware part body 7 to rotate synchronously. When the hardware part body 7 is turned over to the required angular position, release the pull plate. At this time, the contact spring 33 resets, driving the contact disc 32 and the fixed rod 31 to move synchronously. When the fixed rod 31 is inserted into the guide groove inside the rotating disc 8, the rotating disc 8 can be locked. At this time, the angle of the hardware part body 7 can be fixed, so as to facilitate the grinding disc 17 to grind other surfaces of the hardware part body 7, without the need for the staff to manually turn over the hardware part body 7, effectively improving the grinding efficiency of the hardware part body 7.

[0041] In order to adjust the horizontal position of the grinding disc 17 according to actual needs, a transmission plate 11 is fixedly connected to the upper surface of the top plate 10. A third motor 26 is fixedly connected to one side of the transmission plate 11. The output shaft of the third motor 26 is fixedly connected with a lead screw 27 through a coupling. The other end of the lead screw 27 is rotatably connected to the inner side wall of the transmission plate 11. A moving block 28 is threadedly connected to the outside of the lead screw 27. Guide grooves for the movement of the moving block 28 are formed on the contact surfaces of the transmission plate 11 and the top plate 10. The bottom of the moving block 28 is fixedly connected to the upper surface of the bottom plate 12. When it is necessary to adjust the horizontal position of the grinding disc 17, the third motor 26 starts to operate. At this time, the third motor 26 will drive the lead screw 27 to rotate synchronously. The moving block 28 will move synchronously on the outside of the lead screw 27, driving the bottom plate 12 to move synchronously. The bottom plate 12 will then drive the grinding disc 17 to move synchronously. At this time, the horizontal position of the grinding disc 17 can be adjusted according to actual needs, so that the grinding disc 17 can effectively grind the hardware part body 7.

[0042] In addition, in order to facilitate the disassembly and assembly of the grinding disc 17, the installation assembly includes an inner plate 34 fixedly connected inside the installation disc 15. Both sides of the outer wall of the inner plate 34 are fixedly connected with telescopic rods 35. The telescopic ends of the two telescopic rods 35 are both fixedly connected with insertion rods 36. The outside of the two telescopic rods 35 is sleeved with return springs 37. Both of the two return springs 37 abut between the insertion rod 36 and the inner plate 34. Guide grooves for the insertion rod 36 to move are opened on the outside of the installation disc 15 and the connecting sleeve 16. When it is necessary to install the grinding disc 17, only need to press the insertion rod 36 first. At this time, the insertion rod 36 will simultaneously squeeze the telescopic rod 35 and the return spring 37. Then, sleeve the connecting sleeve 16 on the outside of the installation disc 15. When the insertion rod 36 moves into the guide groove outside the connecting sleeve 16, the return spring 37 resets and drives the insertion rod 36 to move synchronously. When the insertion rod 36 is inserted into the guide groove outside the connecting sleeve 16, the connecting sleeve 16 can be fixed to the installation disc 15. At this time, the installation of the grinding disc 17 can be conveniently carried out.
