Description

Technical Field

[0001] This utility model belongs to the field of terrazzo polishing technology, specifically relating to a terrazzo polishing protective kit. Background Technology

[0002] Terrazzo is a concrete product made by mixing aggregates such as crushed stone, glass, and quartz into cement binder. As a building decoration material, terrazzo is widely used in interior and exterior decoration design, curtain wall decoration, and public facility construction. After processing, terrazzo slabs are generally ground and polished with a grinding device to make their surface smooth.

[0003] In the current actual processing of terrazzo, terrazzo slabs are usually placed on a processing table and polished with a grinding wheel. During the polishing process, the high-speed rotation of the grinding wheel generates intense friction with the surface of the terrazzo slab, producing a large amount of abrasive debris. This debris, driven by the high speed of the grinding wheel, often flies in all directions. This flying debris not only seriously pollutes the surrounding processing environment, but also splashes onto the operator's body when the operator is observing the polishing effect, causing injury to their eyes, skin, etc., greatly reducing work safety. Utility Model Content

[0004] The purpose of this utility model is to provide a terrazzo polishing protective kit to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a terrazzo polishing protective kit, comprising:

[0006] The machine base has a housing connected to its top, and a horizontal plate is slidably connected inside the housing. A polishing machine for polishing terrazzo is slidably connected to the bottom of the horizontal plate. A processing table for fixing the terrazzo is connected to the top of the machine base. An opening for loading or unloading terrazzo is provided on the surface of the housing. A protective component for closing the opening is hinged to the surface of the machine base. The protective sleeve of the protective component is flipped towards the opening so that the locking block on the surface of the protective sleeve engages with the fixing block inside the housing, thus fixing the protective sleeve after closing the opening.

[0007] Preferably, the protective component includes an observation window, the protective sleeve is hinged to the surface of the base and the observation window is located on the surface of the protective sleeve, and the locking block is fixed to the surface of the protective sleeve by screws.

[0008] Preferably, the fixing block includes rollers and clamping frames. The clamping frames are provided in two sets and are both located inside the machine housing. The rear ends of the two sets of clamping frames are rotatably connected by a rotating shaft.

[0009] Preferably, the rollers are provided in two sets, and the two sets of rollers are rotatably connected to the front end of the two sets of clamping frames through bearings. A torsion spring is sleeved on the rotating shaft located in the clamping frame, and the two ends of the torsion spring are respectively connected to the two sets of clamping frames. A slot is provided between the two sets of clamping frames, and the locking block passes through the two sets of rollers and locks into the slot.

[0010] Preferably, the two ends of the horizontal plate slide through the slots provided in the inner wall of the chassis and are slidably sleeved on the surface of the slide rod. The top of the chassis is provided with a first cylinder, and the piston rod of the first cylinder moves through the chassis and is connected to the horizontal plate.

[0013] Preferably, the surface of the clamping plate is connected to a protective pad.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By setting up protective components, the protective sleeve of the protective components can tightly close the opening during grinding, forming a relatively closed space, which confines the grinding debris inside and prevents the grinding debris from flying out of the processing area. In addition, the observation window set on the protective sleeve can observe the grinding effect without opening the protective sleeve, so that the operator can clearly see the grinding process through the observation window from a safe distance, avoiding the damage of grinding debris to the body and greatly improving work safety.

[0016] (2) The third cylinders and the clamping plates and protective pads connected to them at both ends of the processing table provide convenience for fixing the terrazzo slabs. The piston rod of the third cylinder can flexibly push the clamping plate to move, adapting to terrazzo slabs of different sizes. By working with the clamping plate in conjunction with the third cylinder, the clamping plate can tightly clamp the terrazzo slabs, preventing the terrazzo slabs from moving during grinding.

[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] This utility model provides, for example Figure 1-3 The terrazzo polishing protective kit shown includes:

[0023] A base 1 is provided, with a housing 2 connected to the top of the base 1 and a horizontal plate 3 slidably connected inside the housing 2. A polishing machine 4 for polishing terrazzo is slidably connected to the bottom of the horizontal plate 3. A processing table 5 for fixing the terrazzo is connected to the top of the base 1. An opening 6 for loading or unloading terrazzo is provided on the surface of the housing 2. A protective component for closing the opening 6 is hinged to the surface of the base 1. The protective sleeve 7 of the protective component is flipped towards the opening 6 so that the locking block 8 on the surface of the protective sleeve 7 engages with the fixing block 9 inside the housing 2, thereby fixing the protective sleeve 7 after closing the opening 6.

[0024] The protective assembly includes an observation window 10, the protective sleeve 7 is hinged to the surface of the base 1 and the observation window 10 is located on the surface of the protective sleeve 7, and the locking block 8 is fixed to the surface of the protective sleeve 7 by screws.

[0025] The fixing block 9 includes rollers 11 and clamping frames 12. The clamping frames 12 are provided in two sets and are both located inside the chassis 2. The rear ends of the two sets of clamping frames 12 are rotatably connected by a rotating shaft 13.

[0026] The rollers 11 are provided in two sets, and the two sets of rollers 11 are rotatably connected to the front end of the two sets of clamping frames 12 through bearings. A torsion spring 14 is sleeved on the rotating shaft 13 located in the clamping frame 12, and the two ends of the torsion spring 14 are respectively connected to the two sets of clamping frames 12. A slot 15 is provided between the two sets of clamping frames 12, and the locking block 8 passes through the two sets of rollers 11 and is locked in the slot 15.

[0027] The two ends of the horizontal plate 3 slide through the slots provided in the inner wall of the housing 2 and are slidably sleeved on the surface of the slide rod 16. The top of the housing 2 is provided with a first cylinder 17, and the piston rod of the first cylinder 17 moves through the housing 2 and is connected to the horizontal plate 3. When the horizontal plate 3 descends, its two ends slide on the surface of the slide rod 16 inside the housing 2. The slide rod 16 guides the direction of the horizontal plate 3 when it descends, thereby enhancing the stability of the horizontal plate 3's movement.

[0028] The horizontal plate 3 is equipped with a second cylinder 18, and the piston rod of the second cylinder 18 is connected to the grinder 4. The horizontal plate 3 is connected with a guide rod 19, and the top of the grinder 4 is slidably sleeved on the surface of the guide rod 19. The guide rod 19 can guide the movement direction of the grinder 4, enhance the stability of the movement of the grinder 4, ensure the linear movement of the grinder 4 during the extension and retraction process, and ensure the grinding accuracy.

[0029] The machine base 1 is equipped with a third cylinder 20 at the top and at both ends of the processing table 5. The piston rod surface of the third cylinder 20 is connected to a clamping plate 21. The piston rods of the two sets of third cylinders 20 push the two sets of clamping plates 21 to move towards the terrazzo slab until the two ends of the terrazzo slab are clamped and fixed.

[0030] The surface of the clamping plate 21 is connected to a protective pad 22, which is made of rubber. The rubber protective pad 22 can prevent the clamping plate 21 from directly contacting the terrazzo slab and prevent the clamping plate 21 from causing scratches, indentations or other damage to the surface of the terrazzo slab under the action of clamping force.

[0031] When the terrazzo polishing protective kit needs to be polished, the terrazzo slab is first placed on the processing table 5, and the two sets of third cylinders 20 are activated. The piston rods of the two sets of third cylinders 20 push the two sets of clamping plates 21 to move towards the terrazzo slab until the two ends of the terrazzo slab are clamped and fixed. The protective pads 22 on the surface of the clamping plates 21 can prevent the clamping plates 21 from directly contacting the terrazzo slab, and prevent the clamping plates 21 from causing scratches, indentations and other damage to the surface of the terrazzo slab under the action of clamping force.

[0032] Then, the protective sleeve 7 is flipped towards the opening 6. When the protective sleeve 7 is flipped, the locking block 8 contacts the roller 11 and presses the two rollers 11 at the front end of the clamping frame 12 inward. The rolling of the two rollers 11 causes the clamping frame 12 to compress the torsion spring 14 and stretch it outward, so that the locking block 8 can be pressed into the slot 15. At the same time, the torsion spring 14 rebounds, causing the two rollers 11 to lock and fix the locking block 8, thereby closing the protective sleeve 7 to the opening 6. At this time, the operator can observe the grinding process through the observation window 10 set on the protective sleeve 7. During the grinding process, the grinding debris generated by the high-speed rotation of the grinding wheel of the grinding machine 4 and the intense friction with the surface of the terrazzo slab is confined in the machine box 2 and cannot be splashed out. After the grinding is completed, the handle on the surface of the protective sleeve 7 can be pulled to move the locking block 8 out of the slot 15, thereby opening the opening 6 and taking out the processed terrazzo slab.

[0033] When polishing is required, the height of the horizontal plate 3 is first adjusted by controlling the extension and retraction of the first cylinder 17. When the piston rod of the first cylinder 17 extends, the horizontal plate 3 descends. When the horizontal plate 3 descends, its two ends slide on the surface of the slide rod 16 inside the housing 2 to enhance the stability of movement. When the horizontal plate 3 is adjusted to a suitable height, the grinding wheel of the polishing machine 4 approaches the terrazzo slab for polishing. During polishing, the second cylinder 18 can be activated. The piston rod of the second cylinder 18 pushes the polishing machine 4 to move back and forth to polish the terrazzo slab. At the same time, the guide rod 19 ensures the linear movement of the polishing machine 4 during the extension and retraction process, ensuring the accuracy of polishing.

[0034] 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.
