However, this method does not have the function of simultaneously grinding vertically, and the grinding direction is always consistent, so the efficiency and quality of grinding cannot be improved. Utility Model Content

[0004] The main purpose of this utility model is to provide a parts grinding device, which aims to solve the technical problem that the existing parts grinding devices have a single grinding direction, which affects the grinding efficiency and quality.

A movable component that can move vertically up and down is pressed against the edge of the fixed plate. A movable plate is slidably fitted at the bottom of the movable component. The movable plate and the hinge plate are connected by a sliding component. A pressing rod is movably fitted on the telescopic sleeve. The control component is used to cooperate with the pressing rod to fix the movable component and the movable plate to each other, so that the grinding rod is stably pressed against the inner wall of the hole.

[0007] The grinding rod, which is stably pressed against the inner wall of the hole, moves up and down repeatedly to grind under the action of the movable part.

[0008] Furthermore, the movable component includes a U-shaped connecting plate, two pressing columns are fitted at the top and bottom of the fixed plate, a sleeve is fixedly connected to the bottom end of the U-shaped connecting plate, the two pressing columns are respectively rotatably connected to the top of the sleeve and the top of the U-shaped connecting plate, a first connecting rod is fixedly connected between the fixed plate and the grinding table, and a limiting component is provided between the sleeve and the movable plate.

[0009] Furthermore, the limiting member includes a second connecting rod, the two ends of which are respectively connected and fixed to the telescopic sleeve and the sleeve. An avoidance groove is provided on one side of the sleeve. The top cross-section of the movable plate is I-shaped, and the movable plate slides within the sleeve.

[0010] Furthermore, the sliding member includes a sliding column, the bottom of the movable plate is provided with a first sliding groove that movably engages with the hinge plate, the sliding column is connected and fixed to the movable plate, and the side of the hinge plate is provided with a second sliding groove that slidably engages with the sliding column.

[0011] Furthermore, a connecting rod is fixedly connected between the sliding columns located at the same horizontal height on the hinge plates at two adjacent positions.

[0012] Furthermore, the control component includes a control rod and a movable rod that are connected and fixed to the pressing rod. The pressing rod has a rectangular frame structure. Multiple slots are provided on the other side of the sleeve and on one side of the movable plate. The movable rod is inserted into and movable with the outer surface of the telescopic sleeve.

[0014] Furthermore, the fixing component consists of multiple elastic pressure plates with an arc-shaped structure. One end of the elastic pressure plate is rotatably connected to the grinding table, and the other end of the elastic pressure plate presses against the top surface of the component.

[0015] Furthermore, the grinding rod includes two arc-shaped rods spaced apart, with multiple insert sleeves connecting the two arc-shaped rods, and multiple compression springs connecting the two arc-shaped rods to ensure that the grinding rods have a tight contact with the inner wall of the hole.

[0016] Furthermore, the grinding table has an clearance hole in the middle, the telescopic sleeve has a convex cross-section, and the telescopic sleeve has a through hole that slides with the convex telescopic sleeve, ensuring that the sleeve rotates and the sleeve slides along the sleeve.

[0017] Beneficial effects:

[0018] The component grinding device of this utility model, by starting the power component, causes the telescopic sleeve rod and telescopic sleeve to rotate, thereby driving the grinding rod, the movable plate and the sleeve to make synchronous circumferential motion, so that the grinding rod grinds along the inner wall of the hole of the component to remove burrs and other defects caused by the stamping process.

[0019] Simultaneously, under the action of the inclined and fixed plate, the circumferentially rotating sleeve, under the action of the two pressure columns, causes the sleeve to move up and down simultaneously. That is, the circumferentially rotating sleeve moves up and down simultaneously, causing the grinding rod to grind the inner wall of the hole of the part while rotating in a circular motion, thus grinding the inner wall of the hole. This achieves synchronous grinding in both vertical and horizontal directions, ensuring the grinding effect. Attached Figure Description

[0036] Reference Figures 1-9This utility model provides a component grinding device, including a grinding table 1, a power component 2 on the grinding table 1, a fixing assembly for fixing components on the grinding table 1, and a grinding rod 3 with holes for grinding components on the power component 2.

[0037] It also includes a sliding component, a control component, a telescopic sleeve 401, and a telescopic sleeve 402. The telescopic sleeve 401 is connected and fixed to the output shaft of the power component 2. A hinge plate 5 is provided between the telescopic sleeve 402 and multiple grinding rods 3. The telescopic sleeve 401 is movably connected through a fixed plate 6 that is inclined and fixed to the grinding table 1. A movable component that can move vertically up and down is pressed against the edge of the fixed plate 6. A movable plate 7 is slidably fitted at the bottom of the movable component. The movable plate 7 is connected to the hinge plate 5 through the sliding component. A pressing rod 8 is movably fitted to the telescopic sleeve 402. The control component is used to cooperate with the pressing rod 8 to fix the movable component and the movable plate 7 to each other, so that the grinding rods 3 are stably pressed against the inner wall of the hole.

[0038] The grinding rod 3, which is stably pressed against the inner wall of the hole, moves up and down and grinds under the action of the moving parts;

[0039] The steps for this application are as follows:

[0040] Positioning preparation: First, place the parts on the grinding table 1, and move the telescopic sleeve 402 downward so that the telescopic sleeve 402, the hinge plate 5, and the grinding rod 3 move downward and enter the hole of the parts.

[0041] Positioning: Move the movable plate 7 upward along the sleeve 11. The upward-moving movable plate 7 drives the hinge plate 5 to rotate, thereby causing multiple grinding rods 3 to move outward simultaneously. This allows the grinding rods 3 to be tightly pressed against the inner wall of the hole of the component, and the component to make an adaptive automatic adjustment position, so that the axis of the hole of the component coincides with the axis of the telescopic sleeve 401 and the telescopic sleeve 402.

[0042] It is worth noting that during this process, the telescopic rod 401 and the telescopic sleeve 402 slide against each other, that is, they slide against each other in the vertical direction.

[0043] Fixing: The components that automatically adjust their position are fixed by fixing the fixing components. Then, by rotating the control component, the pressure rod 8 presses against the sleeve 11 and the movable plate 7 at the same time, thereby connecting and fixing the sleeve 11, the movable plate 7 and the telescopic sleeve 402 to each other.

[0044] It is worth noting that: after being fixed, the telescopic sleeve 401 and the telescopic sleeve 402 will not slide relative to each other, and the angle of the hinge plate 5 will not change thereafter;

[0045] Grinding: Start the power component 2 to make the telescopic sleeve 401 and telescopic sleeve 402 rotate, thereby driving the grinding rod 3, the movable plate 7 and the sleeve 11 to make synchronous circular motion, so that the grinding rod 3 grinds along the inner wall of the hole of the part to remove burrs and other defects from the stamping process.

[0046] Simultaneously, under the action of the inclined and fixed fixed plate 6, the circumferentially rotating sleeve 11, under the action of the two pressing columns 10, causes the circumferentially rotating sleeve 11 to move up and down simultaneously. That is, the circumferentially rotating sleeve 11 moves up and down simultaneously, causing the grinding rod 3 to rotate and grind the inner wall of the hole of the component while moving up and down to grind the inner wall of the hole, thus achieving synchronous grinding in the vertical and horizontal directions and ensuring the grinding effect.

[0047] The movable part includes a U-shaped connecting plate 9, two pressing columns 10 at the top and bottom of the fixed plate 6, a sleeve 11 fixedly connected to the bottom end of the U-shaped connecting plate 9, and the two pressing columns 10 are respectively connected to the top of the sleeve 11 and the top of the U-shaped connecting plate 9 for rotational connection. A first connecting rod 12 is fixedly connected between the fixed plate 6 and the grinding table 1, and a limiting component is provided between the sleeve 11 and the movable plate 7.

[0048] When the control component engages and fixes the movable plate 7 and the sleeve 11, the movable rod 20, the sleeve 11 and the telescopic sleeve 402 are connected and fixed, and the telescopic rod 401 and the telescopic sleeve 402 will not slide relative to each other.

[0049] When the power component 2 is activated, it drives the telescopic sleeve 401 and the telescopic sleeve 402 to rotate, thereby causing the sleeve 11 and the movable plate 7 to revolve around the axis of the telescopic sleeve 401. The grinding rod 3 simultaneously performs a circular motion, thereby grinding the inner wall of the hole in the component.

[0050] The sleeve 11, which is making circular motion, drives the U-shaped connecting plate 9 and the pressing column 10 to make circular motion synchronously. Under the action of the inclined and fixed plate 6, the two pressing columns 10 make circular motion along the inclined plate 6, so that the pressing column 10 makes an appropriate rotational motion. The U-shaped connecting plate 9 and the sleeve 11, which are making circular motion, simultaneously make vertical up-and-down reciprocating motion along the plate 6.

[0051] It is worth noting that during grinding, the pressing rod 8 is simultaneously engaged with the slot 21 on the sleeve 11 and the movable plate 7, thereby fixing the telescopic sleeve 402 and the movable plate 7 to each other. That is, the movable plate 7 and the telescopic sleeve 402 will not move relative to each other. The telescopic sleeve 402 slides up and down along the telescopic sleeve rod 401, thereby ensuring that the hinge plate 5 moves with the telescopic sleeve 402. The hinge plate 5 does not rotate relative to the telescopic sleeve 402, that is, the angle of the hinge plate 5 does not change, so that the grinding rod 3 is always tightly attached to the inner wall of the hole of the part.

[0052] This causes the movable plate 7 and the telescopic sleeve 402 to move vertically up and down, grinding the inner walls of the holes in the parts vertically, achieving synchronous grinding in both vertical and horizontal directions, and ensuring the grinding effect.

[0053] It is worth noting that the end of the pressure column 10 is an inclined surface adapted to the inclined surface of the fixed plate 6, and the end of the pressure column 10 is in a movable pressure fit with the fixed plate 6.

[0054] The limiting component includes a second connecting rod 13, with both ends of the second connecting rod 13 connected and fixed to the telescopic sleeve 402 and the sleeve 11 respectively. A clearance groove 14 is provided on one side of the sleeve 11. The top cross-section of the movable plate 7 is I-shaped. The movable plate 7 slides within the sleeve 11. The sleeve 11 and the telescopic sleeve 402 are always in a relatively immobile state. The movable plate 7 slides along the sleeve 11. The horizontal distance between the movable plate 7 and the telescopic sleeve 402 remains constant. The movable plate 7 rotates in a circle as the telescopic sleeve 402 rotates. The movable plate 7 can only slide in the vertical direction relative to the telescopic sleeve 402 and the sleeve 11.

[0055] The sliding component includes a sliding column 15, a first sliding groove 16 that is movably engaged with the hinge plate 5 is provided at the bottom of the movable plate 7, the sliding column 15 is connected and fixed to the movable plate 7, and a second sliding groove 17 that is slidably engaged with the sliding column 15 is provided on the side of the hinge plate 5.

[0056] The horizontal distance between the sleeve 11 and the telescopic sleeve 402 is always fixed. The movable plate 7 moves upward along the sleeve 11, which drives the sliding column 15 to move upward. The sliding column 15 slides with the second sliding groove 17, thereby driving the hinge plate 5 to rotate, causing the grinding rod 3 to move outward, thereby pressing against the inner wall of the hole in the part.

[0057] It is worth noting that each grinding rod 3, together with the telescopic sleeve 402 and the corresponding two hinge plates 5, forms a parallelogram, so that the grinding rod 3 remains vertical throughout the process of gradually moving closer to and pressing tightly against the inner wall of the hole of the component.

[0058] A connecting rod 18 is fixedly connected between sliding columns 15 at the same horizontal height on two adjacent hinge plates 5. When the movable plate 7 moves up and down relative to the sleeve 11, it drives the hinge plate 5 on the movable plate 7 to rotate. Through the setting of the connecting rod 18, the connecting rod 18 moves up and down synchronously, thereby causing the other hinge plates 5 to rotate synchronously and the multiple grinding rods 3 to unfold synchronously, so that the grinding rods 3 can press tightly against the inner wall of the hole of the part.

[0059] The control components include a control rod 19 and a movable rod 20 that are fixedly connected to the pressing rod 8. The pressing rod 8 has a rectangular frame structure, and multiple slots 21 are provided on the other side of the sleeve 11 and the side of the movable plate 7. The movable rod 20 is inserted into the outer surface of the telescopic sleeve 402. By pulling back the control rod 19 and rotating the control rod 19, the pressing rod 8 is rotated and simultaneously inserted into the slots 21 on the other side of the sleeve 11 and the side of the movable plate 7, thereby locking and fixing the movable plate 7 and the sleeve 11. There is no relative movement between the movable plate 7, the sleeve 11, and the telescopic sleeve 402, so that when the movable components move up and down, the sleeve 11, the movable plate 7, and the telescopic sleeve 402 move up and down synchronously. This allows the grinding rod 3, which moves in a circular motion, to grind the holes of the parts horizontally while moving up and down to grind vertically, ensuring the grinding quality.

[0060] A fixed plate 22 is fixedly connected to the telescopic sleeve 402. The fixed plate 22 has an insertion groove 23. A gear 24 is fixedly connected to the end of the movable rod 20. The gear 24 is inserted into the insertion groove 23. By pulling the control rod 19 outward, the gear 24 is disengaged from the insertion groove 23. Then, the control rod 19 is rotated, causing the pressing rod 8 to rotate. The gear 24 rotates synchronously, so that the pressing rod 8 is simultaneously engaged in the slots 21 on the sleeve 11 and the movable plate 7. Finally, the control rod 19 is pushed, so that the gear 24, after the angle adjustment, is re-engaged in the insertion groove 23, so that a stable engagement is formed between the movable plate 7 and the sleeve 11. That is, the movable plate 7, the sleeve 11, and the telescopic sleeve 402 are connected and fixed.

[0061] The fixing component consists of multiple arc-shaped elastic pressure plates 25. One end of the elastic pressure plate 25 is rotatably connected to the grinding table 1, and the other end of the elastic pressure plate 25 presses against the top surface of the part. The grinding table 1 has a through groove in the middle and is stepped in the middle. When the part is placed on the grinding table 1, the hole of the part corresponds to the through groove. When multiple grinding rods 3 press against the inner wall of the hole of the part at the same time, the part moves to adjust its position and completes the hole positioning of the part. That is, the telescopic sleeve 402 is located at the center of the hole of the part. Then, the part is fixed after the position is adjusted by rotating the elastic pressure plate 25.

[0062] The grinding rod 3 includes two arc-shaped rods spaced apart. Multiple insert sleeves 26 are inserted between the two arc-shaped rods. Multiple compression springs are also attached between the two arc-shaped rods. When the grinding rod 3 presses against the inner wall of the hole of the part, the compression springs make the grinding rod 3 press tightly against the inner wall of the hole of the part.

[0063] The grinding table 1 has an clearance hole 27 in the middle. The telescopic sleeve 401 has a convex cross-section. The telescopic sleeve 402 has a through hole that slides with the convex telescopic sleeve 401, so that when the telescopic sleeve 401 rotates, it drives the telescopic sleeve 402 to rotate at the same time, without affecting the sliding of the telescopic sleeve 402 along the telescopic sleeve 401.

[0064] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
