Description

Technical Field

[0001] This utility model relates to the field of workpiece grinding technology, specifically to a modular adjustable grinding device. Background Technology

[0002] Modular reversible grinding heads are grinding units that can be quickly replaced through standardized interfaces. They support multi-directional adjustments (such as axial, radial, or combined movements) to adapt to the surface treatment needs of complex workpieces. The precision adjustment mechanism is the control core of the grinding system, responsible for adjusting the position, pressure, and feed rate of the grinding head in real time to ensure stable and compliant processing accuracy.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN217194379U discloses "a workpiece grinding device", which includes a worktable. The upper ends of both sides of the worktable are fixedly connected to fixed plates. The top of the fixed plates is fixedly connected to a first electric push rod. The output end of the first electric push rod is fixedly connected to a connecting block. The two sides of the rear end of the top of the worktable are fixedly connected to support columns. The two connecting blocks are connected to movable plates through the support columns on opposite sides.

[0004] While existing grinding devices can improve grinding efficiency and reduce worker labor intensity by using a motor to drive the grinding block to grind the workpiece on top of the displacement plate, in actual use, the output end of the second electric push rod is rigidly connected to the push plate (such as bolt fixing) to achieve the clamping function. However, this structure makes it difficult to replace the push plate. Disassembly requires loosening multiple bolts and other fasteners, which is time-consuming and cannot quickly replace the push plate, reducing the flexibility and adaptability of the grinding equipment. Therefore, we propose a modular adjustable grinding device. Utility Model Content

[0028] 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.

[0029] Example 1

[0030] Please see Figures 1-4This utility model provides a technical solution: a modular adjustable grinding device, including a grinding device body 1, and further comprising:

[0031] U-shaped mounting bracket 2 is set on the grinding device body 1 and is used to support the workpiece to be ground;

[0032] Two connecting brackets 4 are slidably mounted on top of the U-shaped mounting bracket 2;

[0033] Two L-shaped connectors 5 are respectively set on the top of the two connecting frames 4 and are used to clamp the workpiece to be ground.

[0034] Two sets of connecting components 100 are respectively set on two connecting brackets 4 to realize the detachable connection of L-shaped connectors 5;

[0035] The drive unit 50 is mounted on the connecting frame 4 and is used to drive the two connecting frames 4 to slide symmetrically along the U-shaped mounting frame 2.

[0036] The connecting assembly 100 also includes two connecting holes 6 opened on the top of the L-shaped connector 5. A first bidirectional lead screw 102 is rotatably connected inside the connecting frame 4. The top of the connecting frame 4 has two second rectangular guide holes 103 that cooperate with the two connecting holes 6. The outer wall of the first bidirectional lead screw 102 is provided with two moving blocks 105 by threads. The tops of the two moving blocks 105 pass through the second rectangular guide holes 103 and are provided with abutment plates 106. One end of the first bidirectional lead screw 102 passes through the connecting frame 4 and is provided with a hand crank. The outer wall of the hand-cranked disc 104 is provided with anti-slip texture. The first bidirectional lead screw 102 can be easily rotated by the hand-cranked disc 104. When the first bidirectional lead screw 102 rotates, the two moving blocks 105 will move relative to or away from each other along the thread direction of the first bidirectional lead screw 102, thereby driving the abutment plate 106 to move. The abutment plate 106 then abuts against the edge of the connecting hole 6 of the L-shaped connector 5, realizing the stable clamping or loosening of the L-shaped connector 5, which facilitates the quick replacement of the L-shaped connector 5 and improves the flexibility and adaptability of the grinding equipment.

[0037] The drive unit 50 also includes two pairs of first rectangular guide holes 3 opened on the U-shaped mounting bracket 2. The interior of the U-shaped mounting bracket 2 is rotatably connected to a second bidirectional lead screw 52. The U-shaped mounting bracket 2 is also equipped with a motor 51 for driving the second bidirectional lead screw 52 to rotate. The outer wall of the second bidirectional lead screw 52 is provided with two symmetrically distributed connecting plates 53 through threads. The two ends of the two connecting plates 53 are respectively provided with connecting blocks 54. The tops of the two pairs of connecting blocks 54 pass through the two pairs of first rectangular guide holes 3 and are connected to the connecting bracket 4. The second bidirectional lead screw 52 is driven to rotate by the motor 51. When the second bidirectional lead screw 52 rotates, the two connecting plates 53 will move relative to or away from each other along the thread direction of the second bidirectional lead screw 52, ​​thereby driving the connecting blocks 54 to slide in the first rectangular guide holes 3. The connecting blocks 54 then drive the connecting bracket 4 to slide symmetrically along the top of the U-shaped mounting bracket 2, so as to grind the workpiece to be ground held on the L-shaped connector 5.

[0038] Rollers 55 are rotatably connected to both pairs of connecting blocks 54, and the outer wall of the rollers 55 abuts against one side of the grinding device body 1. The setting of the rollers 55 reduces the friction between the connecting blocks 54 and the grinding device body 1, making the connecting blocks 54 slide more smoothly, while protecting the surface of the grinding device body 1 and avoiding scratches or damage caused by friction.

[0039] In practical use, various clamps for holding workpieces can be fixed on multiple L-shaped connectors 5. When it is necessary to install the L-shaped connector 5 on the connecting frame 4, firstly, the first bidirectional lead screw 102 can be rotated by turning the hand crank 104 counterclockwise. The rotation of the first bidirectional lead screw 102 causes the two moving blocks 105 to move towards the center of the connecting frame 4, thus facilitating the penetration of the two connecting holes 6 on the L-shaped connector 5 through the abutment plate 106. After the L-shaped connector 5 successfully penetrates the abutment plate 106, the L-shaped connector 5 can be successfully placed on the connecting frame 4. At the top of the connecting frame 4, the hand crank 104 is rotated clockwise, causing the first bidirectional lead screw 102 to rotate. The two moving blocks 105 will move outward along the thread direction of the first bidirectional lead screw 102, thereby driving the abutment plate 106 to abut against the top position of the L-shaped connector 5, realizing the stable clamping of the L-shaped connector 5. At this time, the workpiece to be ground can be placed between the two L-shaped connectors 5, and the two connecting frames 4 are driven by the drive unit 50 to slide symmetrically along the U-shaped mounting frame 2, so that the L-shaped connector 5 clamps and fixes the workpiece to be ground.

[0040] When it is necessary to replace the L-shaped connector 5, simply turn the hand crank 104 counterclockwise again to loosen the clamping plate 106 on the L-shaped connector 5, and then the L-shaped connector 5 can be removed from the connecting frame 4. After replacement, it can be reinstalled on the connecting frame 4 according to the above steps. The whole replacement or adjustment process is simple and quick, without the need to disassemble multiple fasteners, which greatly improves the flexibility and adaptability of the grinding equipment.

[0041] Example 2

[0042] Please see Figures 5-6 This utility model provides a technical solution:

[0043] Unlike Example 1;

[0044] The top of each of the two connecting frames 4 is provided with a mounting plate 10, the outer wall of the hand crank 104 is provided with a ratchet 11, and one side of the ratchet 11 abuts against the connecting frame 4. One side of the mounting plate 10 is rotatably connected with a pawl 12 that works with the ratchet 11. The pawl 12 is located on the top of the ratchet 11, and a mounting rod 13 is provided on the pawl 12.

[0045] In use, the pawl 12 and ratchet 11 work together to fix the position of the hand crank 104 after rotation, preventing the first bidirectional lead screw 102 from rotating due to external force, thus ensuring the stability of the L-shaped connector 5 during clamping. When it is necessary to adjust the position of the L-shaped connector 5 or replace the L-shaped connector 5, the pawl 12 can be manually lifted to separate it from the ratchet 11. At this time, the hand crank 104 can be rotated freely to adjust or replace the L-shaped connector 5.
