Description

Technical Field

[0001] This utility model relates to the field of grinding equipment, and in particular to a high-stability self-lifting clamping mechanism for grinding mills. Background Technology

[0002] In traditional crystal glass bead polishing machines, a clamping mechanism is installed above the frame, and a grinding disc mechanism is installed below the frame. The clamping mechanism has multiple rows of clamping seats arranged in a row to simultaneously clamp multiple polishing parts. A rotating motor on the clamping row rotates the clamping row, and a self-rotating motor on the clamping disc rotates the clamping seats, thereby adjusting the angle of the polishing parts relative to the grinding disc. The grinding disc mechanism drives the grinding disc to rotate and lift, thus controlling the polishing depth of the polishing parts. However, in traditional polishing mechanisms, the vertical lifting of the grinding disc needs to be controlled during rotation. This lifting control is affected by the rotation of the grinding disc, resulting in poor control accuracy, poor uniformity of polished parts in the same batch, and product quality issues. However, if the lifting control mechanism is moved to the clamping bar, the force on the clamping bar will affect the lifting control mechanism when the clamping bar is tilted for grinding, resulting in poor durability. In addition, the lifting control mechanism needs to support the entire clamping bar structure. When the lifting control mechanism controls the clamping bar to descend to control the grinding depth, the descent process is easily affected by the downward pull of the entire clamping bar structure's gravity, resulting in poor stability of the grinding depth control.

[0003] Therefore, the existing clamping mechanisms in mills suffer from poor durability and poor stability in controlling the grinding depth. Utility Model Content

[0004] The purpose of this invention is to provide a highly stable self-lifting clamping mechanism for grinding mills. This invention not only improves durability but also has the advantage of better control and stability of grinding depth.

[0005] The technical solution of this utility model is as follows: A high-stability self-lifting clamping mechanism for a grinding mill includes a mounting base arranged in a gantry frame shape; a lifting block is vertically slidably connected to one side of the mounting base, and an electric telescopic shaft fixed vertically on the mounting base is connected between the lifting block and the mounting base; an elastic telescopic component for bearing the weight of the lifting block is connected between the mounting base and the lifting block; a horizontally arranged clamping row is rotatably connected to the lifting block, and multiple clamping seats arranged in a row for clamping grinding parts are rotatably connected to the clamping row; a rotary motor for driving the clamping row to rotate relative to the lifting block is connected to one side of the lifting block, and a self-rotating motor for driving all clamping seats on the clamping row to rotate synchronously is connected to the other side of the lifting block.

[0006] In the aforementioned high-stability self-lifting clamping mechanism for a mill, multiple elastic telescopic components are provided, and all elastic telescopic components are distributed on both sides of the electric telescopic shaft.

[0007] In the aforementioned high-stability self-lifting clamping mechanism for a mill, the elastic telescopic component includes a fixed seat fixed on a mounting base, a smooth rod vertically slidably mounted on the fixed seat, the bottom end of the smooth rod being fixedly connected to a lifting block, and a pressure plate being threadedly connected to the top end of the smooth rod; a compression spring located between the pressure plate and the fixed seat is sleeved on the top of the smooth rod, and a sleeve fixed on the fixed seat is sleeved on the compression spring and the pressure plate.

[0008] In the aforementioned high-stability self-lifting clamping mechanism for a mill, multiple vertically arranged slide rails are fixedly connected to the side of the mounting base near the lifting block, and a slider fixed on the lifting block is slidably sleeved on the outside of each slide rail.

[0009] In the aforementioned high-stability self-lifting clamping mechanism for a mill, the slide rail is provided with concave sliding limit grooves on both sides; the slider is provided with sliding limit protrusions corresponding to the sliding limit grooves.

[0010] In the aforementioned high-stability self-lifting clamping mechanism for mills, a worm gear is rotatably connected inside the clamping row, horizontally penetrating the clamping row and meshing with all clamp seats. One end of the worm gear is connected to the output shaft of the self-rotating motor. When the output shaft of the self-rotating motor rotates, it can drive the worm gear to rotate, thereby driving all clamp seats to rotate synchronously.

[0011] Compared with the prior art, this utility model has a higher stability when the lifting block moves up and down relative to the mounting base by connecting an electric telescopic shaft that is vertically fixed on the mounting base between the mounting base and the lifting block, and by making the lifting block vertically slidably connected to the mounting base. When the grinding part is tilted for grinding, the force on the electric telescopic shaft is distributed by the sliding connection between the lifting block and the mounting base, thereby reducing the wear between the inner shaft and the outer sleeve when the electric telescopic shaft drives the lifting block to move up and down, and improving durability. At the same time, by connecting an elastic telescopic component between the lifting block and the mounting base to bear the weight of the lifting block, the influence of the weight of the lifting block on the electric telescopic shaft's control of the lifting block's descent is reduced, improving the stability of the grinding depth control. Moreover, the elastic telescopic component can extend and retract without affecting the lifting block's movement up and down relative to the mounting base.

[0012] In addition, the elastic telescopic components in this utility model are multiple components distributed on both sides of the electric telescopic shaft, so that the mounting base can more stably hold the lifting block through two elastic telescopic components.

[0013] The elastic telescopic component allows the weight of the lifting block to act on the compression spring through the smooth rod and pressure plate. When the electric telescopic shaft controls the descent of the lifting block to control the grinding depth, only the compression spring needs to be compressed, which can better control the grinding depth. By providing a sleeve fixed on the fixed seat around the compression spring and pressure plate, the lifting of the smooth rod and the extension of the compression spring have high stability.

[0014] By connecting multiple sets of vertically sliding slide rails and sliders between the mounting base and the lifting block, and making each set of slide rails and sliders slide and engage with each other through sliding limit grooves and sliding limit protrusions, the force exerted by the lifting block on the mounting base during inclined grinding can be better distributed by the slider and slide rail structure, and is less likely to act on the electric telescopic shaft, thus reducing the wear between the inner shaft and outer sleeve during the lifting control of the electric telescopic shaft.

[0015] Therefore, this invention not only improves durability, but also has the advantages of good control stability of grinding depth and high structural stability. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0024] Example. A high-stability self-lifting clamping mechanism for a mill, configured as follows: Figures 1 to 6As shown, it includes a mounting base 1 arranged in a gantry frame shape; a lifting block 2 is vertically slidably connected to one side of the mounting base 1, and an electric telescopic shaft 3, vertically fixed on the mounting base 1, is connected between the lifting block 2 and the mounting base 1; an elastic telescopic member 4 for bearing the weight of the lifting block 2 is connected between the mounting base 1 and the lifting block 2; a horizontally arranged clamping row 5 is rotatably connected to the lifting block 2, and multiple clamping seats 6 arranged in a row for clamping grinding parts are rotatably connected to the clamping row 5; a rotary motor 7 for driving the clamping row 5 to rotate relative to the lifting block 2 is connected to one side of the lifting block 2, and a self-rotating motor 8 for driving all the clamping seats 6 on the clamping row 5 to rotate synchronously is connected to the other side of the lifting block 2.

[0025] Multiple elastic telescopic components 4 are provided, and all elastic telescopic components 4 are distributed on both sides of the electric telescopic shaft 3.

[0026] The elastic telescopic component 4 includes a fixed base 9 fixed on the mounting base 1, a linear rod 10 vertically slidably mounted on the fixed base 9, the bottom end of the linear rod 10 being fixedly connected to the lifting block 2, and a pressure plate 11 threadedly connected to the top end of the linear rod 10; a compression spring 12 located between the pressure plate 11 and the fixed base 9 is sleeved on the top of the linear rod 10, and a sleeve 13 fixed on the fixed base 9 is sleeved on the compression spring 12 and the pressure plate 11.

[0027] Multiple vertically arranged slide rails 14 are fixedly connected to one side of the mounting base 1 near the lifting block 2. Each slide rail 14 is slidably sleeved with a slider 15 fixed on the lifting block 2. The slide rail 14 is provided with concave sliding limit grooves 16 on both sides. The slider 15 is provided with sliding limit protrusions 17 corresponding to the sliding limit grooves 16.

[0028] The clamping row 5 is rotatably connected to a worm gear 18 that runs horizontally through the clamping row 5 and meshes with all the clamping seats 6. One end of the worm gear 18 is connected to the output shaft of the self-rotating motor 8. When the output shaft of the self-rotating motor 8 rotates, it can drive the worm gear 18 to rotate, thereby driving all the clamping seats 6 to rotate synchronously.

[0029] Working principle: When grinding is required on the workpiece held at the bottom of the clamping seat 6, the electric telescopic shaft 3, which is vertically fixed on the mounting seat 1, drives the lifting block 2 to descend. At this time, the elastic telescopic component 4 between the lifting block 2 and the mounting seat 1 extends (the lifting block 2 drives the polished rod 10 to descend relative to the fixed seat 9 fixed on the mounting seat 1, so that the pressure plate 11 threaded at the top of the polished rod 10 slides downward in the sleeve 13 and compresses the compression spring 12 between the pressure plate 11 and the fixed seat 9). The electric telescopic shaft 3 is not pulled down by the gravity on the lifting block 2, and the downward control stability of the lifting block 2 relative to the mounting seat 1 is better, thus better controlling the grinding depth of the workpiece. At this time, the clamping row 5, which is horizontally rotatably connected to the lifting block 2, and the multiple rows of clamping seats 6 distributed on the clamping row 5 can move down synchronously. When the workpiece held on the clamping seat 6 comes into contact with the grinding disc, grinding can begin.

[0030] During the lifting and lowering process of the electric telescopic shaft 3, multiple sliders 15 on the lifting block 2 slide on multiple vertical slide rails 14 on the mounting base 1. The two sliding limit protrusions 17 on the slider 15 slide in the sliding limit grooves 16 on both sides of the slide rail 14. The sliding stability of the lifting block 2 relative to the mounting base 1 is relatively high. During grinding, the force exerted by the lifting block 2 on the mounting base 1 can be distributed by the slidingly engaged sliders 15 and slide rails 14, which reduces the force and wear between the inner shaft and outer sleeve of the electric telescopic shaft 3 when it is in motion.

[0031] The rotating motor 7 fixed on one side of the lifting block 2 can drive the clamping row 5 to rotate relative to the lifting block 2, so that the tilt angle of the clamping seat 6 on the clamping row 5 relative to the grinding disc changes, thereby changing the grinding angle of the grinding workpiece; the self-rotating motor 8 fixed on the other side of the lifting block 2 can drive the worm gear 18 to rotate, so that all the clamping seats 6 meshing on the worm gear 18 rotate on the clamping row 5, thereby adjusting the grinding surface of the grinding workpiece relative to the grinding disc.
