Description

Technical Field

[0001] This utility model relates to the field of grinding workbench technology, and in particular to a grinding workbench that facilitates sandpaper replacement. Background Technology

[0002] A grinding table is a specially designed work platform or device for grinding, polishing, and other processing operations. It provides operators with a stable, safe, and convenient operating environment, and is equipped with various tools, fixtures, or fixing devices to ensure the workpiece remains stable during the grinding process, achieving ideal processing results. In the production of notebook computer baseboards, the use of a grinding table is primarily to ensure that the surface quality meets high standards, satisfying both aesthetic and functional requirements. By using sandpaper or other grinding tools on the grinding table, burrs, scratches, or unevenness left after preliminary processing such as milling and cutting are effectively removed, improving the surface flatness and smoothness of the baseboard, thus laying a solid foundation for subsequent processes.

[0003] Existing grinding tables mainly use clamps such as steel clips or pressure plates to firmly hold the sandpaper, and users manually push the clamps to grind the laptop's bottom plate. However, if it is necessary to change the sandpaper, some clamps must be disassembled, and special tools are required, making the replacement process inconvenient.

[0004] Therefore, those skilled in the art have provided a grinding worktable that facilitates sandpaper replacement to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grinding workbench that facilitates sandpaper replacement. The inner clamping plate is rotated by the extension and retraction of the first electric telescopic rod, thereby achieving automatic adjustment of the clamping mechanism and making it convenient for users to replace sandpaper.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding workbench that facilitates sandpaper replacement, comprising a main body, a crossbar, and a serpentine cable tray. Support frames are fixedly installed at the front and rear of the upper end of the main body. The front and rear ends of the crossbar are movably sleeved on the middle of the upper ends of the two support frames, and one end of the serpentine cable tray is movably sleeved on the middle of the crossbar. A clamping mechanism is fixedly installed at the other end of the serpentine cable tray.

[0007] The clamping mechanism includes a grip cylinder, inside which a first electric telescopic rod is fixedly installed. Both sides of the lower end of the grip cylinder are fixedly installed with outer clamping plates. Both sides of the output end of the first electric telescopic rod are hinged with connecting blocks. The lower ends of the two connecting blocks are hinged with inner clamping plates. The opposite sides of the middle of the two inner clamping plates are respectively hinged to the opposite sides of the middle of the two outer clamping plates.

[0008] Furthermore, a base plate is fixedly installed at the center of the upper end of the main body platform, and a second electric telescopic rod is fixedly installed at a diagonal position on one side of the upper end of the main body platform.

[0009] Furthermore, a first clamping block is fixedly provided at the output end of the second electric telescopic rod, and a second clamping block is fixedly provided at a diagonal position on one side of the upper end of the base plate.

[0010] Furthermore, an elastic buckle is fixedly fitted on one side of the support frame located at the front of the upper part of the main body platform.

[0011] Furthermore, a switch is provided at the center of the front end of the grip.

[0012] Furthermore, the switch is electrically connected to the first electric telescopic rod.

[0013] This utility model has the following beneficial effects:

[0014] This invention proposes a grinding workbench that facilitates sandpaper replacement. A switch controls the retraction of a first electric telescopic rod, moving two connecting blocks. These blocks then rotate two inner clamping plates upwards, creating a gap between the lower ends of the inner and outer clamping plates. The user places the sandpaper in this gap and then uses the first electric telescopic rod to push the two connecting blocks, causing the inner clamping plates to rotate downwards and hold the sandpaper in place. In this way, the user can easily clamp and release the sandpaper simply by controlling the switch, making sandpaper replacement convenient. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Reference Figure 1 , Figure 2 An embodiment of this utility model provides a grinding workbench that facilitates sandpaper replacement, comprising a main body 1, a crossbar 3, and a serpentine cable tray 4. Support frames 2 are fixedly installed at the front and rear of the upper end of the main body 1. The front and rear ends of the crossbar 3 are respectively movably sleeved on the middle of the upper end of the two support frames 2. One end of the serpentine cable tray 4 is movably sleeved on the middle of the body of the crossbar 3. The other end of the serpentine cable tray 4 is fixedly installed with a clamping mechanism 5. An elastic buckle 10 is fixedly sleeved on one side of the support frame 2 located at the front of the upper end of the main body 1.

[0023] Specifically, since the front and rear ends of the crossbar 3 are respectively movably mounted on the two support frames 2, and one end of the serpentine cable tube 4 is movably mounted on the crossbar 3, when the user moves the grip 501, it will first drive the serpentine cable tube 4 to move on the crossbar 3, and then drive the crossbar 3 to move between the two support frames 2, so that the crossbar 3 moves synchronously with the grip 501, so that the grip 501 can provide auxiliary support no matter where it moves on the bottom of the laptop.

[0024] Secondly, the serpentine conduit 4 has the characteristic of bending in any direction, which makes it easy for users to adjust the angle of the grip 501 at will, thereby achieving grinding in different directions. In addition, after the user finishes grinding, the grip 501 can be placed in the elastic buckle 10, which can easily store the grip 501.

[0025] Reference Figure 3 , Figure 4 The clamping mechanism 5 includes a gripping cylinder 501, inside which a first electric telescopic rod 502 is fixedly installed. On both sides of the lower end of the gripping cylinder 501, outer clamping plates 503 are fixedly installed. On both sides of the output end of the first electric telescopic rod 502, connecting blocks 504 are hinged. On the lower end of the two connecting blocks 504, inner clamping plates 505 are hinged. The opposite sides of the middle of the two inner clamping plates 505 are respectively hinged to the opposite sides of the middle of the two outer clamping plates 503. A switch 506 is provided in the middle of the front end of the gripping cylinder 501. The switch 506 is electrically connected to the first electric telescopic rod 502.

[0026] Specifically, since the two connecting blocks 504 are hinged on both sides of the output end of the first electric telescopic rod 502, and the lower ends of the two connecting blocks 504 are respectively hinged to two inner clamping plates 505, when the first electric telescopic rod 502 is pulled back, it will first straighten the two connecting blocks 504, and then drive the two inner clamping plates 505 to rotate around their own hinge points as support points, so that the lower ends of the two inner clamping plates 505 are moved away from the lower ends of the two outer clamping plates 503. At this time, the user can place sandpaper between the lower ends of the inner clamping plates 505 and the outer clamping plates 503.

[0027] Reference Figure 1 , Figure 2 A base plate 6 is fixedly installed at the center of the upper end of the main body platform 1. A second electric telescopic rod 7 is fixedly installed at the diagonal of one side of the upper end of the main body platform 1. A first clamping block 8 is fixedly installed at the output end of the second electric telescopic rod 7. A second clamping block 9 is fixedly installed at the diagonal of one side of the upper end of the base plate 6.

[0028] Specifically, the first clamping block 8 and the second clamping block 9 are both designed with right angles on opposite sides. This design allows the two clamping blocks to adapt to different sizes of laptop base plates. During operation, the user first places one corner of the base plate inside the second clamping block 9 and aligns it with its inner corner. Then, the user activates the second electric telescopic rod 7 through the controller to push the first clamping block 8 to hold the other corner of the base plate, thus fixing the position of the laptop base plate and preventing it from sliding or shifting during the grinding process.

[0029] Working principle: The user places the notebook base plate to be processed onto the substrate 6, aligning one corner of the base plate with the angle of the second clamping block 9. Then, the user activates the second electric telescopic rod 7 via the controller. The second electric telescopic rod 7 pushes the first clamping block 8 to move to the other corner of the notebook base plate, thereby clamping and fixing the base plate. Next, the user stops the second electric telescopic rod 7. Then, the user grasps the grip sleeve 501 and controls the first electric telescopic rod 502 via the switch 506 to pull it back, causing the two connecting blocks 504 to move upward. Then, through the two hinged connecting blocks 504, the two inner clamping plates 505 are respectively driven to rotate upward with their central hinge points as support. At this time, a gap appears at the lower ends of the two inner clamping plates 505 and the two outer clamping plates 503. The user places the two ends of the sandpaper into the gaps respectively, and then controls the first electric telescopic rod 502 via the switch 506 to push the two connecting blocks 504, thereby causing the two inner clamping plates 505 to rotate downward and clamp and fix the sandpaper.

[0030] Secondly, the user grips the grip 501 and grinds the laptop base with the sandpaper that has been clamped and fixed. During the grinding process, when the user moves the position of the grip 501, the crossbar 3 moves on the support frame 2 in sync through the serpentine cable tube 4, which assists in supporting the user to carry out the grinding work.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
