Abstract
Description
Technical Field
[0001] This utility model relates to the field of building processing, and in particular to a grinding machine for building materials. Background Technology
[0002] Grinding machines (also known as filing machines) are key equipment used for precision machining and surface polishing of workpieces in mold manufacturing, metal processing and other fields. With the technological iteration of pneumatic tools, they are widely used, especially in the pretreatment process of rusted materials (such as steel structures and concrete surfaces) in the construction industry.
[0003] However, when using existing grinding machines, workers typically hold the workpiece by hand or use clamping tools (pliers) to move and grind it. In manual operation mode, operators need to adjust the pressure based on experience, which can easily lead to inaccurate grinding thickness (depth) due to subjective factors, resulting in excessive wear on the workpiece or failure to remove rust. Therefore, a grinding machine for building materials is needed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a grinding machine for building materials, which solves the problem that it is not easy to control the grinding thickness during the current grinding process.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A building material grinding machine, comprising:
[0007] A base, wherein a frame is fixedly provided on one side of the top of the base;
[0008] The progressive push assembly includes a transverse plate arranged horizontally on the left side of the frame base, a push plate rotatably connected to the left end of the transverse plate, and a rotating plate rotatably mounted on the top of the base. The rotating plate is located below the push plate, and a movable rod is fixedly provided at the bottom of the push plate. The movable rod is inserted into the interior of the rotating plate, and the interior of the rotating plate has a movable hole for the movable rod to move up and down.
[0009] The limiting assembly includes a fixing plate fixed to the left side of the inner wall of the frame base and a limiting rod inserted into the top of the fixing plate. The fixing plate is located above the transverse plate. The bottom of the limiting rod is fixed with a locking tooth. The top of the transverse plate is horizontally provided with a toothed row, and the locking tooth engages with the toothed row.
[0010] Furthermore, a movable block is fixed at one end of the movable rod located in the movable hole, the movable block slides inside the movable hole, and a first spring is provided inside the movable hole to abut against one end of the movable block.
[0011] Furthermore, a second spring is provided between the locking teeth and the fixing plate, and the second spring is sleeved on the limiting rod.
[0012] Furthermore, an opening is provided on the left side of the frame base at the position of the horizontal plate, and multiple rollers are provided at the top and bottom of the inner wall of the opening, with the outer surface of the rollers in contact with the horizontal plate.
[0013] Furthermore, it also includes a clamping assembly, which includes a U-shaped block fixed to one end of the transverse plate located inside the frame, clamping blocks disposed on two transverse arms on the inner wall of the U-shaped block, and a cylinder connected to one of the clamping blocks.
[0014] Furthermore, a receiving box is fixedly provided on the top of the base on one side of the frame, and a discharge pipe hole is opened on one side of the receiving box and connected to an air suction pipe.
[0015] Furthermore, a conversion block is provided horizontally inside the receiving box, and a rocker arm is provided on one side of the receiving box, with one end of the rocker arm connected to the conversion block.
[0016] Furthermore, a water receiving groove is provided on the top of the conversion block, and a water receiving hole is provided inside the conversion block. One end of the water receiving hole is connected to the water receiving groove, and the other end is connected to the discharge pipe hole.
[0017] Furthermore, the bottom of the conversion block is provided with multiple air intake holes, and the interior of the conversion block is provided with horizontally spaced air gathering holes. The multiple air intake holes are connected to the air gathering holes, and the positions of the air gathering holes are symmetrically arranged with the positions of the discharge pipe holes.
[0018] Furthermore, a grinding machine body is mounted on the top of the base on one side of the progressive assembly, and a cutting tool is mounted on the output end of the grinding machine body, with the cutting tool located above the receiving box.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] 1. By using a progressive push assembly in conjunction with a limiting assembly, the workpiece can be ground without being held by hand or with a hand clamp during processing. The grinding thickness can be controlled during grinding. Specifically, when the push plate in the progressive push assembly is pushed, it rotates and moves downwards, causing the movable rod and the movable hole to move downwards. This push plate moves the transverse plate, which in turn moves the workpiece laterally, eliminating the need to hold the workpiece by hand or with a hand clamp. Furthermore, this structure makes the workpiece more stable during grinding. The limiting rod on the limiting assembly and the locking teeth connected to the bottom of the limiting rod mesh with the toothed row on the transverse plate. As the transverse plate moves, the locking teeth pass through the teeth on the toothed row sequentially. The grinding thickness can be determined by the number of teeth the locking teeth pass through, thus controlling the grinding thickness of the workpiece.
[0021] 2. Through the receiving box, in conjunction with the internal conversion block, the conversion block can clean up the waste material or water generated during grinding. For example, when water cooling is required during grinding, the wastewater dripping from grinding will be absorbed by the water receiving tank and guided out. When water cooling is not required, the conversion block is rotated so that the air intake hole faces upward, absorbing the dust generated during the grinding process. That is, the air intake hole generates suction to absorb and discharge the dust. Attached Figure Description

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0033] The building material grinding machine provided in this embodiment of the utility model is suitable for use in the fields of mold manufacturing and metal processing for workpiece finishing and surface polishing. By improving the structure of the building material grinding machine, it has the advantages of easy control of grinding thickness during the grinding process.
[0034] This utility model embodiment provides a building material grinding machine; please refer to [link / reference]. Figure 1 and Figure 5The system includes: a base 1, a progressive assembly, and a limiting assembly. A frame 3 is fixed to one side of the top of the base 1. The progressive assembly includes a transverse plate 4 horizontally disposed on the left side of the frame 3, a push plate 5 rotatably connected to the left end of the transverse plate 4, and a rotating plate 6 rotatably disposed on the top of the base 1. The rotating plate 6 is located below the push plate 5. A movable rod 501 is fixed to the bottom of the push plate 5 and inserted into the interior of the rotating plate 6. The rotating plate 6 has a movable hole 601 inside for the movable rod 501 to move up and down. The limiting assembly includes a fixed plate 9 fixed to the left side of the inner wall of the frame 3 and... A limiting rod 10 is inserted into the top of the fixed plate 9. The fixed plate 9 is located above the horizontal plate 4. A locking tooth 11 is fixed at the bottom of the limiting rod 10. A toothed row 13 is laid horizontally on the top of the horizontal plate 4. The locking tooth 11 meshes with the toothed row 13. A movable block 502 is fixed at one end of the movable rod 501 located in the movable hole 601. The movable block 502 slides inside the movable hole 601. A first spring 7 is provided inside the movable hole 601 to abut one end of the movable block 502. A second spring 12 is provided between the locking tooth 11 and the fixed plate 9. The second spring 12 is sleeved on the limiting rod 10.
[0035] like Figure 1 and Figure 5 As shown, a frame seat 3 is fixed on the top of the base 1. The base 1 provides stability for the overall equipment. The frame seat 3 serves as the core frame, integrating other functional components (progressive and limiting) to ensure structural rigidity. The progressive component includes a horizontal plate 4, a push plate 5, a rotating plate 6, a movable rod 501, and a movable hole 601. The horizontal plate 4 is horizontally fixed on the left side of the frame seat 3, serving as the track base for workpiece advancement. The push plate 5 is rotatably connected to the left end of the horizontal plate 4, driving the workpiece to move towards the grinding area through swinging. The rotating plate 6 is rotated on the top of the base 1, located below the push plate 5, and achieves progressive advancement through linkage with the movable rod 501. The movable rod 501 is fixed to the bottom of the push plate 5 and inserted into the movable hole 601 of the rotating plate 6, restricting the movable rod 501 to only move up and down, converting the rotational motion of the push plate 5 into the swinging motion of the rotating plate 6, forming a mechanical displacement amplification mechanism. Progressive feed: The feed amount is finely adjusted by lever principle (the proportional relationship between the swing amplitude of rotating plate 6 and the displacement of movable rod 501), which solves the problem of uneven feed caused by air pressure fluctuation in traditional cylinder drive. It also eliminates the need to hold the workpiece by hand or with a hand clamp for grinding, and allows control of the workpiece grinding thickness during grinding.
[0036] The limiting assembly includes a fixed plate 9, a limiting rod 10, a locking tooth 11, and a toothed row 13. The fixed plate 9 is fixed to the left side of the inner wall of the frame base 3, serving as the mounting base for the limiting rod 10. The limiting rod 10 has locking teeth 11 at its bottom, which mesh with the toothed row 13 at the top of the transverse plate 4. The toothed row 13 is laid horizontally on the top of the transverse plate 4, providing discrete positioning points. The limiting principle is based on the toothed row 13, which consists of multiple teeth, each with a certain thickness. As the locking tooth 11 moves on the toothed row 13, different numbers of teeth correspond to different grinding thicknesses. Simultaneously, when the workpiece stops moving, the locking tooth 11 and the toothed row 13 mesh together, creating a fixing effect and preventing the transverse plate 4 from moving automatically.
[0037] Specifically, the initial position of the transverse plate 4 is adjusted according to the workpiece length (loosen the limit rod 10, slide the transverse plate 4 to the target tooth position and then lock it), and gradually advances: drive the push plate 5 to swing clockwise around the left end of the transverse plate 4, the push plate 5 drives the movable rod 501 to press down, the movable rod 501 moves down in the movable hole 601 of the rotating plate 6, forcing the rotating plate 6 to swing counterclockwise around the axis of the base 1. When the rotating plate 6 swings, its right end pushes the workpiece to move towards the grinding machine tool 201 (the swing angle is proportional to the displacement). After each advancement is completed, the locking teeth 11 of the limit rod 10 automatically engages with the tooth row 13 to lock the position of the transverse plate 4; when the feed amount needs to be adjusted, lift the limit rod 10 to disengage from the tooth row 13, and the transverse plate 4 can slide freely to the next tooth position, or directly push the push plate 5 to move the transverse plate 4.
[0038] Please see Figure 1 An opening is provided on the left side of the frame 3 at the position of the horizontal plate 4. Multiple rollers are provided at the top and bottom of the inner wall of the opening, and the outer surface of the rollers is in contact with the horizontal plate 4.
[0039] like Figure 1 As shown, the size of the opening is adapted to the horizontal plate 4, allowing the horizontal plate 4 to move laterally. A row of rollers is horizontally arranged at the top and bottom positions inside the opening, and the rollers, one above the other, clamp the horizontal plate 4, making the horizontal movement of the horizontal plate 4 smoother.
[0040] Please see Figure 5 It also includes a clamping assembly 8, which includes a U-shaped block fixed to one end of the transverse plate 4 located inside the frame 3, a clamping block on two transverse arms on the inner wall of the U-shaped block, and a cylinder connected to one of the clamping blocks.
[0041] like Figure 5As shown, the U-shaped block is fixed to one end of the transverse plate 4 inside the frame 3. The inner wall has two horizontal arms. The U-shaped block serves as the base of the clamping assembly 8 and is rigidly connected to the frame 3 through the transverse plate 4 to ensure a stable clamping force transmission path. The double horizontal arm design makes the clamping blocks symmetrically distributed on both sides of the workpiece, avoiding workpiece displacement caused by unilateral force application (especially suitable for long strip building materials such as steel beams). The clamping blocks are located on the two horizontal arms on the inner wall of the U-shaped block and directly contact the workpiece. The inner surface of the clamping block can be equipped with anti-slip textures or rubber pads (not limited, but expandable) to increase the friction coefficient (friction coefficient ≥ 0.4) and prevent workpiece slippage caused by grinding vibration. The cylinder is connected to one of the clamping blocks and acts as an active force source to push one side of the clamping block to move, achieving rapid clamping / releasing (response time ≤ 0.5 seconds).
[0042] Please see Figure 1 , Figure 3 and Figure 4 A receiving box 14 is fixedly installed on the top of the base 1 on one side of the frame 3. A discharge pipe hole 1401 is opened on one side of the receiving box 14 and is connected to an air suction pipe. A conversion block 15 is horizontally arranged inside the receiving box 14. A rocker arm 16 is rotated on one side of the receiving box 14. One end of the rocker arm 16 is connected to the conversion block 15. A water receiving trough 1501 is opened on the top of the conversion block 15, and a water receiving hole 1502 is opened inside the conversion block 15. One end of the water receiving hole 1502 is connected to the water receiving trough 1501, and the other end is connected to the discharge pipe hole 1401. Multiple air suction holes 1503 are opened at the bottom of the conversion block 15, and a gathering air hole 1504 is horizontally opened inside the conversion block 15. The multiple air suction holes 1503 are connected to the gathering air hole 1504. The position of the gathering air hole 1504 is symmetrically arranged with the position of the discharge pipe hole 1401.
[0043] like Figure 1 , Figure 3 and Figure 4 As shown, the receiving box 14 is fixedly installed on the top of the base 1, located on one side of the frame 3, to collect and collect grinding debris (metal shavings, concrete slag, etc.), reducing splash pollution. The discharge pipe hole 1401 is connected to the suction pipe. Technical features: The receiving box 14 has a discharge pipe hole 1401 on one side, which is connected to the suction pipe. The suction pipe is connected to an external wet / dry vacuum cleaner (negative pressure ≥5kPa) to suck up light dust into a centralized treatment device (such as a bag filter), reducing the dust concentration in the working environment to ≤5mg / m³ (compliant with...). (OSHA standard), the conversion block 15 is horizontally arranged inside the receiving box 14. Functional division: the conversion block 15 divides the inside of the receiving box 14 into upper and lower layers. The upper layer collects liquids (such as wet grinding wastewater), and the lower layer collects dust (dry grinding). A rocker arm 16 is rotated on one side of the receiving box 14. One end of the rocker arm 16 is connected to the conversion block 15. Manual operation: the operator rotates the rocker arm 16 (angle range 0°-90°) to drive the conversion block 15 to slide or rotate horizontally and switch the collection mode.
[0044] Water suction mode: Due to gravity, the wastewater from grinding drips into the water receiving tank 1501. Due to the structural design of the water receiving tank 1501, the wastewater can flow into the water receiving hole 1502 that is connected to the water receiving tank 1501. The discharge pipe hole 1401 of the receiving box 14 connects with the water receiving hole 1502, which can suck out the wastewater. Furthermore, the end of the water receiving hole 1502 and one end of the discharge pipe hole 1401 are equipped with waterproof rings that can be interlocked to allow the wastewater to be discharged smoothly.
[0045] Suction mode: Push the rocker arm 16 to rotate the conversion block 15 so that the side of the conversion block 15 with the suction hole 1503 faces upward. At the same time, because the air gathering hole 1504 and the discharge pipe hole 1401 are symmetrically arranged, when the suction hole 1503 faces upward, the air gathering hole 1504 and the discharge pipe hole 1401 are connected. At the same time, a sealing ring is set on the side of the air gathering hole 1504 that is connected to the discharge pipe hole 1401, which can be locked with the waterproof ring and also plays a positioning role. After the waste is sucked in by multiple suction holes 1503, it is discharged into the interior of the air gathering hole 1504 and then discharged from the discharge pipe hole 1401.
[0046] The focus of this embodiment is on changing the working mode. The function of the water tank 1501 and the air intake 1503 is to absorb and clean sewage and dust, which is well known to those skilled in the art and will not be elaborated in this embodiment.
[0047] Please see Figure 1 and Figure 2 The base 1 is mounted on one side of the progressive assembly and the grinding machine body 2 is mounted on the top. The output end of the grinding machine body 2 is equipped with a cutting tool 201, which is located above the receiving box 14.
[0048] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
