Description

Technical Field

[0001] This utility model relates to the field of quartz stone trimming technology, specifically to a device for fine trimming of artificial quartz stone. Background Technology

[0002] Quartz stone is a new type of artificial stone made of over 90% quartz crystals, resin, and other trace elements. It is produced by pressing large-format slabs using specialized machinery under specific physical and chemical conditions. Due to its unique properties and beautiful appearance, quartz stone is widely used in architectural decoration and home renovation.

[0003] After the artificial quartz stone products are manufactured, they need to be polished and trimmed because the edges are sharp or irregular. Currently, various grinding wheels are used for trimming. Manual hand-grinding is physically demanding and cannot ensure that the entire edge is smooth. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A device for fine trimming artificial quartz stone includes a crossbeam, on which a long cylindrical frame that moves along the crossbeam is mounted. A bearing seat is fixed to the front side of the bottom of the long cylindrical frame, and a fixed shaft is mounted on the bearing seat. A grinding wheel is mounted at the front end of the fixed shaft, and a motor is mounted on the long cylindrical frame at the rear end of the fixed shaft. The output end of the motor is fixedly connected to the fixed shaft at the corresponding position.

[0006] Furthermore, an elongated sleeve is installed on the crossbeam on the side of the elongated frame. The elongated sleeve is installed with the elongated frame, and its bottom abuts against the crossbeam for support. A limit plate is fixed on the elongated sleeve near the crossbeam, and the limit plate and the elongated sleeve are sleeved onto the crossbeam to form a sleeve connection. The elongated sleeve allows the elongated frame to rotate around the crossbeam.

[0007] Furthermore, a fixing plate is fixed inside the elongated sleeve above the limiting plate. A gear is installed at the upper inner side of the elongated sleeve, and a shaft is fixed at the middle of the gear. A fixing seat is fixed on the fixing plate at the corresponding end of the shaft. The shaft is installed with the fixing seat at the corresponding position. The crossbeam is cylindrical and has multiple equally spaced toothed grooves. The gear meshes with the toothed grooves. The gear provides a meshing connection with the crossbeam and rotates to adjust the angle.

[0008] Furthermore, the number of teeth on the gear is not equal to the number of grooves in the tooth groove. A threaded rod is fixed to the end of the shaft on the right side of the elongated sleeve. A locking nut that abuts against the corresponding fixed seat is threaded onto the threaded rod. An adjustment knob is fixed to the right end of the threaded rod away from the shaft. The locking nut is used to lock the position of the elongated sleeve and prevent it from rotating arbitrarily.

[0009] Furthermore, a limiting groove is formed on the inner side of the elongated frame. A collar is installed inside the elongated frame at the position of the limiting groove. The collar abuts against the limiting groove to form a limiting sliding support with the elongated frame. The collar is sleeved on the crossbeam to form a sleeve connection. The collar and the elongated frame are fixed. A fixing block is fixed on the collar facing upwards from the elongated frame. An adjusting rod is installed on the fixing block. The adjusting rod passes through the elongated frame at the corresponding position and is threaded to each other. Rotating the adjusting rod can adjust the extension length of the elongated frame relative to the collar.

[0010] Furthermore, a limiting block is fixed to the end of the adjusting rod facing the fixed block. A slot is cut in the fixed block corresponding to the position of the limiting block. The limiting block is located in the slot and is rotatably connected to the limiting block. Both the limiting block and the slot have a T-shaped cross-section that cooperates with each other. This satisfies the requirements for the rotation of the adjusting rod itself and the sleeve connection between the collar and the crossbeam.

[0011] Furthermore, both ends of the crossbeam are fixed with ground-supported uprights, and the bottom of the uprights at both ends of the crossbeam is fixed with support plates. Diagonal braces are fixed between the support plates and the corresponding uprights. This increases the structural stability of the entire device.

[0012] Furthermore, a guide groove is provided at the bottom of the support plate, and a transverse guide rail is installed below the support plate. The transverse guide rail abuts against the guide groove to form a sliding support. The upright and crossbeam can be moved along the transverse guide rail for neat trimming operations.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model features a crossbeam and a long cylindrical frame that can move along the crossbeam. The grinding wheel is fixed to the long cylindrical frame. During grinding and trimming, the grinding wheel is fixed and supported by the long cylindrical frame, eliminating the need for manual handling and saving effort. At the same time, the long cylindrical frame can move along the crossbeam, which helps to ensure the smooth movement of the grinding wheel and ultimately ensures the flatness of the quartz stone edge.

[0015] 2. In this utility model, an elongated sleeve and an elongated frame are used for fixing. The elongated sleeve can rotate around the crossbeam, thereby adjusting the tilt angle of the grinding wheel to meet the fine finishing effect of different corner angles. At the same time, it is equipped with gears and locking nuts to have a position limiting effect and prevent random rotation.

[0016] 3. In this utility model, by setting an adjusting rod on the elongated frame and cooperating with the collar, the extension length of the elongated frame relative to the crossbeam can be adjusted. In combination with the angle adjustment effect of the gear, the edge treatment of quartz stones of different specifications and sizes can be performed, and the flexibility of use is improved.

[0017] 4. In this utility model, the transverse guide rail and the support plate are used to easily move the entire crossbeam transversely, thereby driving the grinding wheel to move transversely and smooth and polish the entire edge of the quartz stone. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides a device for fine edge trimming of artificial quartz stone, mainly solving the problems of high physical labor burden and low flatness of manual grinding with handheld grinders. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-6 Please provide a detailed explanation:

[0027] A device for fine trimming of artificial quartz stone includes a crossbeam 1, which is cylindrical. Both ends of the crossbeam 1 are fixed with a stand 2, which is supported on the ground. An elongated frame 13 is installed on the crossbeam 1.

[0028] A bearing seat 19 is fixed to the front side of the bottom of the elongated cylindrical frame 13. A fixed shaft 20 is installed on the bearing seat 19. A grinding wheel 21 is installed at the front end of the fixed shaft 20. A motor 22 is installed on the elongated cylindrical frame 13 at the rear end of the fixed shaft 20. The output end of the motor 22 is fixedly connected to the fixed shaft 20 at the corresponding position.

[0029] When using the equipment, place the artificial quartz stone to be polished and trimmed close to the crossbeam 1, or move the crossbeam 1 close to the quartz stone so that the front grinding surface of the grinding wheel 21 abuts against the top edge of the quartz stone to be polished. Then start the motor 22. The motor 22 drives the fixed shaft 20 to rotate, which in turn drives the grinding wheel 21 to rotate. The front grinding surface of the rotating grinding wheel 21 polishes the top edge of the quartz stone, completing the trimming operation.

[0030] In some embodiments, an elongated sleeve 3 is installed on the crossbeam 1 on the side of the elongated frame 13. The elongated sleeve 3 is installed on the elongated frame 13, and the bottom of the elongated sleeve 3 abuts against the crossbeam 1 for support. A limiting plate 4 is fixed on the elongated sleeve 3 near the crossbeam 1. The limiting plate 4 and the elongated sleeve 3 are sleeved on the crossbeam 1 to form a sleeve connection.

[0031] A fixing plate 5 is fixed inside the elongated sleeve 3 above the limiting plate 4. A gear 7 is installed on the upper inner side of the elongated sleeve 3. A shaft 9 is fixed in the middle of the gear 7. A fixing seat 6 is fixed on the fixing plate 5 at the end of the shaft 9. The two ends of the shaft 9 are installed with the fixing seats 6 at the corresponding positions.

[0032] The crossbeam 1 has multiple equally spaced toothed grooves 8. The gear 7 meshes with the toothed grooves 8. The number of teeth of the gear 7 is not equal to the number of grooves of the toothed grooves 8. The end of the shaft 9 on the right side of the long cylindrical sleeve 3 is fixed with a threaded rod 10. The threaded rod 10 is threaded with a locking nut 11 that abuts against the corresponding fixed seat 6. The right end of the threaded rod 10 away from the shaft 9 is fixed with an adjustment knob 12.

[0033] When grinding and trimming, the angle of the grinding wheel 21 can be adjusted to create different grinding edges. To adjust, first loosen the locking nut 11, then turn the adjusting knob 12. Using the fixed relationship between the threaded rod 10 and the shaft 9, the gear 7 will rotate. Then, by meshing the gear 7 with the tooth groove 8, the entire elongated sleeve 3 and the elongated frame 13 will rotate around the crossbeam 1, thereby adjusting the tilt angle of the grinding surface on the front side of the grinding wheel 21. After adjustment, tighten the locking nut 11 to press it firmly against the fixed seat 6. The gear 7 will not be able to rotate, thus forming a limit lock. It should be noted that the number of teeth of the gear 7 and the number of grooves of the tooth groove 8 must be different. Otherwise, even if the gear 7 cannot rotate, it can still revolve around the crossbeam 1 because the number of teeth and grooves are completely opposite, and the locking effect cannot be obtained. When the number of teeth and the number of grooves are not equal, if the entire elongated sleeve 3 rotates around the crossbeam 1, but the crossbeam 1 cannot rotate, the contact points of the teeth of the gear 7 and the tooth groove 8 cannot be aligned, resulting in jamming and forming a lock.

[0034] In some embodiments, a limiting groove 15 is provided on the inner side of the elongated frame 13, and a collar 14 is installed in the elongated frame 13 at the position of the limiting groove 15. The collar 14 abuts against the limiting groove 15 to form a limiting sliding support with the elongated frame 13. The collar 14 is sleeved on the crossbeam 1 to form a sleeve connection, and the collar 14 is fixed with the elongated sleeve 3.

[0035] A fixing block 17 is fixed on the collar 14 at a position facing the elongated frame 13. An adjusting rod 16 is installed on the fixing block 17. The adjusting rod 16 passes through the elongated frame 13 at the corresponding position and is threadedly connected to each other.

[0036] During edge trimming, the height of the grinding wheel 21 can be actively adjusted according to the different heights of the quartz stone to meet the edge trimming needs of quartz stones of different heights. When adjusting, rotate the adjusting rod 16, and use the threaded connection with the elongated frame 13. With the limiting cooperation of the collar 14 and the limiting slide 15, the forward extension length of the elongated frame 13 relative to the collar 14 is adjusted with the collar 14 as the reference. Combined with the angle adjustment of the gear 7, it can meet the edge trimming needs of more sizes and specifications of quartz stones.

[0037] In some embodiments, a limiting block 18 is fixed to the end of the adjusting rod 16 facing the fixing block 17. A slot is cut in the fixing block 17 corresponding to the position of the limiting block 18. The limiting block 18 is located in the slot and is rotatably connected to limit the movement. Both the limiting block 18 and the slot are T-shaped structures with mutually cooperating cross sections.

[0038] When the adjusting rod 16 rotates, the collar 14, which is fitted onto the crossbeam 1, can only move laterally along the crossbeam 1, creating a resistance to rotation. By setting a limit block 18 that engages with the groove, the requirements of both the adjusting rod 16 rotating and the collar 14 moving laterally along the crossbeam 1 can be met simultaneously.

[0039] In some embodiments, support plates 23 are fixed to the bottom of the uprights 2 at both ends of the crossbeam 1, and diagonal braces 24 are fixed between the support plates 23 and the uprights 2 at the corresponding positions.

[0040] The upright 2 and the crossbeam 1 form a portal structure. If this structure lacks additional fixation, it will be unstable. Therefore, a support plate 23 is set to increase the contact area with the ground, and a diagonal brace 24 is used to increase the support strength and stability of the entire structure.

[0041] In some embodiments, a guide groove 26 is provided at the bottom of the support plate 23, and a transverse guide rail 25 is installed below the support plate 23. The transverse guide rail 25 abuts against the guide groove 26 to form a sliding support.

[0042] When in use, the support plate 23 can support the ground and push the stand 2. By using the cooperation of the guide groove 26 and the transverse guide rail 25, the support plate 23 can move along the transverse guide rail 25, thereby moving the grinding wheel 21 transversely. The grinding wheel 21 can move along the top edge of the quartz stone. Alternatively, the elongated frame 13 can be directly pushed, so that the gear 7 and the tooth groove 8 are limited. At the same time, the gear 7 slides in the tooth groove 8 to drive the grinding wheel 21 to move transversely.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
