Abstract
Description
Technical Field
[0001] This application relates to the field of polishing technology, and in particular to a granite edge polishing positioning fixture. Background Technology
[0002] Granite is a type of tectonic rock formed when volcanic lava, under considerable pressure, rises to the Earth's surface and, instead of erupting onto the ground, slowly cools and solidifies underground. It is widely used in architectural decoration, home countertops, and tombstones. In these applications, the edge treatment of stone slabs (such as polishing, chamfering, and grooving) is one of the key processes that determines the aesthetics and quality of the final product.
[0003] Currently, in the stone processing industry, the common positioning and clamping methods for polishing the edges of slabs often involve using universal clamps such as flat-jaw pliers and pressure plates to fix the stone on the workbench, and then polishing is performed using mobile equipment or the workbench. Although this method is safer than hand-held, granite slabs come in a wide variety of sizes and thicknesses, requiring frequent adjustments to the universal clamps, making the positioning process cumbersome and inefficient. Therefore, we propose a granite edge polishing positioning clamp to solve the above problems. Utility Model Content
[0004] This application provides a granite edge polishing positioning fixture that enables two positioning seats to automatically and synchronously clamp from both sides of the slab without the need for repeated manual measurement and adjustment. This achieves rapid automatic centering and positioning, greatly improving clamping efficiency, and is especially suitable for granite slabs of different widths.
[0005] This application provides a granite edge polishing positioning fixture, including a base, a feeding mechanism mounted on the upper surface of the base, a feeding table mounted on the top of the feeding mechanism, two positioning seats on the upper surface of the feeding table, a dual-output shaft motor mounted inside the feeding table, two sliding plates inside the feeding table, a threaded sleeve fixedly embedded in the middle of each sliding plate, an adjusting screw threadedly connected inside each threaded sleeve, the ends of the two adjusting screws that are close to each other being connected to the two output ends of the dual-output shaft motor, and the ends of the two adjusting screws that are far apart being connected to the inner wall of the feeding table through bearings, and a set of sliding holes opened on the left and right sides of the feeding table, with a sliding rod slidably connected inside each sliding hole.
[0006] Furthermore, one end of each sliding rod is connected to the outer surface of the positioning seat, and the other end of each sliding rod is connected to the sliding plate. A connecting rod is fixedly connected between each group of sliding rods, and the threads of the two adjusting screws are in opposite directions.
[0007] Furthermore, the feeding mechanism includes two bearing seats mounted on the upper surface of the base, a feed screw rotatably connected between the two bearing seats, a screw seat threadedly connected to the outer surface of the feed screw, the top end of the screw seat being connected to the bottom surface of the feed table, and a rocker wheel mounted at the front end of the feed screw.
[0008] Furthermore, two guide rails are fixedly connected to the upper surface of the base, and a sliding plate is slidably connected inside each guide rail. The top of each sliding plate is connected to the bottom surface of the feed table.
[0009] Furthermore, two mounting plates are fixedly connected to the bottom surface of the base, and each mounting plate has two mounting holes on its upper surface.
[0010] Furthermore, the front and back of the feed table are provided with heat dissipation holes arranged at equal intervals, and a maintenance cover is installed on the upper surface of the feed table by screws.
[0011] Furthermore, a control switch is installed on the front of the feed table, and the control switch is electrically connected to the dual output shaft motor via a wire.
[0012] Compared with the prior art, the beneficial effects of this utility model are: The technical solution provided in this application has at least the following technical effects or advantages: 1. This utility model uses a dual-output shaft motor to drive two adjusting screws with opposite thread directions to rotate synchronously, causing two sliding plates and their connected positioning seats to move in opposite directions. This enables the two positioning seats to automatically and synchronously clamp from both sides of the plate, eliminating the need for repeated manual measurement and adjustment. This achieves rapid automatic centering and positioning, greatly improving clamping efficiency. It is especially suitable for granite slabs of different widths. The positioning seats are connected to the sliding plates by multiple sliding rods and reinforced by connecting rods, forming a frame structure with excellent rigidity. This structure can reliably withstand the lateral forces and vibrations generated during polishing, preventing the workpiece from shifting or shaking during processing, thus ensuring the stability of edge polishing.
[0013] 2. This utility model uses a feeding mechanism where the operator can drive the feed screw by turning the rocker wheel, causing the entire feeding table and the clamped stone to move smoothly and precisely along the guide rail. The operator can control the feed amount and position of the stone edge relative to the polishing wheel, achieving a uniform and consistent polishing effect and improving the controllability of processing quality.

[0015] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0016] Example 1: Please see Figure 1-4 In this utility model, a granite edge polishing positioning fixture includes a base 1. A feeding mechanism 9 is mounted on the upper surface of the base 1. A feeding table 7 is mounted on the top of the feeding mechanism 9. Two positioning seats 3 are provided on the upper surface of the feeding table 7. A dual-output shaft motor 15 is installed inside the feeding table 7. Two sliding plates 16 are provided inside the feeding table 7. A threaded sleeve 18 is fixedly embedded in the middle of each sliding plate 16. An adjusting screw 17 is threadedly connected inside each threaded sleeve 18. The two adjusting screws 17 are respectively connected to the two output ends of the dual-output shaft motor 15 at their respective close ends. The ends that are furthest apart are connected to the inner wall of the feed table 7 via bearings. A set of sliding holes 13 are provided on both the left and right sides of the feed table 7. A sliding rod 5 is slidably connected inside each sliding hole 13. The two adjusting screws 17 with opposite thread directions are driven to rotate synchronously by the dual output shaft motor 15, which drives the two sliding plates 16 and the positioning seats 3 connected to them to move in opposite directions. This enables the two positioning seats 3 to automatically and synchronously clamp from both sides of the plate without the need for repeated manual measurement and adjustment. This achieves fast and accurate automatic centering and positioning, which greatly improves clamping efficiency and is especially suitable for granite slabs of different widths.
[0017] Example 2: The feed mechanism 9 includes two bearing seats 901 mounted on the upper surface of the base 1. A feed screw 902 is rotatably connected between the two bearing seats 901. A screw seat 903 is threaded onto the outer surface of the feed screw 902. The top end of the screw seat 903 is connected to the bottom surface of the feed table 7. A rocker wheel 904 is mounted on the front end of the feed screw 902. Two guide rails 12 are fixedly connected to the upper surface of the base 1. A slide plate 10 is slidably connected inside each guide rail 12. The top end of each slide plate 10 is connected to the feed screw 902. The bottom surface of the table 7 is connected. Through the feeding mechanism 9, the operator can drive the feed screw 902 by turning the rocker wheel 904, which will drive the entire feeding table 7 and the clamped stone to move smoothly and accurately along the guide rail 12. The operator can accurately control the feed amount and position of the stone edge relative to the polishing wheel, achieving a uniform and consistent polishing effect and improving the controllability of processing quality. The overall structure consists of the base 1, the guide rail 12 and the rigid feeding table 7, which ensures the stability of the equipment under heavy-load polishing conditions.
[0018] One end of each sliding rod 5 is connected to the outer surface of the positioning seat 3, and the other end of each sliding rod 5 is connected to the sliding plate 16. A connecting rod 4 is fixedly connected between each group of sliding rods 5. The threads of the two adjusting screws 17 are opposite. The positioning seat 3 is connected to the sliding plate 16 through multiple sliding rods 5 and reinforced by the connecting rods 4, forming a frame structure with excellent rigidity. This structure can reliably withstand the lateral force and vibration generated during the polishing process, preventing the workpiece from shifting or shaking during processing, thereby ensuring the accuracy and stability of the edge polishing process. Two mounting plates 14 are fixedly connected to the bottom surface of the base 1. Two mounting holes are opened on the upper surface of each mounting plate 14. 8. The front and back of the feed table 7 are provided with equally spaced heat dissipation holes 11. The upper surface of the feed table 7 is fitted with a maintenance cover plate 2 by screws. The front of the feed table 7 is fitted with a control switch 6, which is electrically connected to the dual output shaft motor 15 through wires. The control switch 6 allows the motor to be operated with one button, which is simple and intuitive. The maintenance cover plate 2 facilitates the maintenance of the mechanism in the feed table 7. The heat dissipation holes 11 facilitate the heat dissipation inside the feed table 7. The mounting plate 14 and mounting holes 8 facilitate the installation of the positioning fixture. The fixture has an automatic centering function and can adapt to various granite slabs within a large size range. It has strong versatility and reduces the number of special fixtures in the workshop.
[0019] The working principle of this application is: The granite slab to be polished is placed between two positioning seats 3 on the upper surface of the feed table 7. The dual output shaft motor 15 is started by the control switch 6. The dual output shaft motor 15 synchronously drives the two adjusting screws 17 to rotate. Since the threads of the two adjusting screws 17 are opposite, they drive the two threaded sleeves 18 and the sliding plate 16 fixed thereto to move in opposite directions (i.e., moving closer or further away from each other). The sliding plate 16 drives the two positioning seats 3 to move synchronously towards each other through the sliding rod 5, automatically centering and firmly clamping the slab from the left and right sides. This achieves fast and adaptive clamping of slabs of different widths, solving the problem of "frequent adjustment, cumbersome positioning process, and low efficiency" of general-purpose clamps in the background technology.
[0020] The operator manually rotates the rocker wheel 904 of the feed mechanism 9, which drives the feed screw 902 to rotate, driving the screw seat 903 and the entire feed table 7 to move smoothly back and forth along the guide rail 12. By precisely controlling the position of the feed table 7, the edge of the granite being held is precisely aligned with and contacts the fixed polishing equipment, achieving continuous and uniform polishing of the entire edge. During the polishing process, the stable clamping force provided by the fixture ensures the processing accuracy and prevents the workpiece from moving.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present application, based on the technical solution and concept of the present application, should be covered within the scope of protection of the present application.
