Description

Technical Field

[0001] This utility model relates to the field of workpiece grinding technology, specifically a grinding device for processing anchor plates. Background Technology

[0002] Anchor plates are cast iron components embedded in concrete, primarily used in prestressed concrete structures. Their main function is to distribute the concentrated force acting on the beam during tensioning, preventing crushing of the concrete at the beam ends. Due to processing and manufacturing processes, anchor plates often suffer from uneven surfaces and burrs on the edges. These issues affect the connection effect and installation quality of the anchor plates. Therefore, grinding is necessary during the processing of anchor plates.

[0003] like Figure 3 The anchor plate shown is a common type of anchor plate in the prior art. It includes an anchor plate body 11. An assembly groove 12 for installing anchors is opened at the center of the upper end surface of the anchor plate body 11 and is coaxially aligned with it. Since it needs to be tightly assembled with the anchors, the flatness and smoothness of the upper end surface of the anchor plate body 11 are required to be high.

[0004] Currently, when grinding the upper surface of the anchor plate body 11, due to the concave design of the assembly groove 12, the upper surface of the anchor plate body 11 has two planes and one circumferential surface. Traditional grinding equipment can mostly only grind one plane of the anchor plate (the upper surface of the anchor plate body 11). After grinding, it is still necessary to manually hold a tool or use another grinding equipment to grind the other plane and circumferential surface a second time. In addition, the inner wall of the anchor plate body 11 also needs to ensure a certain smoothness, so a third grinding operation is required. The overall grinding efficiency is low, resulting in a decrease in overall processing efficiency, which is not conducive to the production efficiency of enterprises. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model proposes a grinding device for processing anchor plates.

[0006] The present invention discloses a grinding device for processing anchor plates, comprising a rotating shaft driven by a motor, and a grinding component mounted on the rotating shaft. The grinding component has a first grinding section, a second grinding section, and a third grinding section, and the first grinding section, the second grinding section, and the third grinding section correspond to and are adapted to the upper end face of the anchor plate body, the inner wall of the assembly groove, and the inner wall of the anchor plate body, respectively. The rotating shaft drives the first grinding section, the second grinding section, and the third grinding section to rotate, thereby performing rotational grinding on the corresponding positions.

[0007] The first grinding section corresponds to the upper surface of the anchor plate body. Its shape and size are designed to fit the upper surface, enabling comprehensive and uniform grinding of the upper surface while the motor drives the shaft to rotate, ensuring its flatness and smoothness. The second grinding section is adapted to the inner wall of the assembly groove. Due to the special structure of the assembly groove, the design of the second grinding section can fit tightly to its inner wall, effectively removing burrs and uneven parts of the inner wall. The third grinding section corresponds to the inner wall of the anchor plate body and can grind the inside of the anchor plate. The three grinding sections work simultaneously, changing the limitation of traditional grinding equipment that can only grind different parts one by one, realizing multi-part grinding at one time, and greatly improving grinding efficiency.

[0008] As a further optimized solution of this utility model, the first grinding section is pressed onto the upper end face of the anchor plate body, the second grinding section is set in the assembly groove and fits against the inner wall of the assembly groove, the third grinding section is set in the inner cavity of the anchor plate body and fits against its inner wall, and the first grinding section and the third grinding section are fixedly connected through the second grinding section.

[0009] The first grinding section presses against the upper surface of the anchor plate body, ensuring that the plane is fully covered and effectively ground during grinding. The second grinding section is located inside the assembly groove and fits tightly against the inner wall. This fitting method ensures that all parts of the assembly groove are meticulously ground, leaving no uneven areas untouched. The third grinding section fits against the inner wall inside the anchor plate body, ensuring the smoothness of the inner cavity. The first and third grinding sections are fixedly connected through the second grinding section, forming an integrated grinding structure. This allows the three grinding sections to rotate synchronously when the shaft rotates, stably grinding their respective corresponding parts and ensuring the continuity and consistency of the grinding process.

[0010] As a further optimized solution of this utility model, the second grinding section is L-shaped with the inner right angle facing upward. The first right angle side of the second grinding section fits against the inner circumferential surface of the assembly groove, and the second right angle side of the second grinding section presses against the bottom surface of the inner cavity of the assembly groove.

[0011] The L-shaped design of the second grinding section is to better adapt to the structure of the assembly slot. The first right-angled edge fits against the inner circumference of the assembly slot, allowing grinding along the circumference to remove imperfections. The second right-angled edge presses against the bottom surface of the inner cavity of the assembly slot, allowing grinding of the bottom surface and ensuring that the bottom surface of the assembly slot also achieves the required flatness and smoothness. The upward-facing inner right angle provides better stability for the second grinding section within the assembly slot, preventing it from easily shaking or shifting during grinding, thus ensuring the precision and quality of the grinding.

[0012] As a further optimized solution of this utility model, the upper end face of the first right-angled side of the second grinding section is flush with the upper end face of the anchor plate body and is fixedly connected to the end of the first grinding section.

[0013] The upper end face of the first right-angled side of the second grinding section is flush with the upper end face of the anchor plate body, ensuring that the upper end face of the anchor plate body will not be over-ground or unevenly ground when grinding the circumference of the assembly groove. It is fixedly connected to the end of the first grinding section, so that the first grinding section and the second grinding section form a stable whole. When the shaft rotates, the two can work together to grind the upper end face of the anchor plate body and the circumference of the assembly groove at the same time, improving grinding efficiency and quality.

[0014] As a further optimized solution of this utility model, the second right-angled side of the second grinding section extends toward the center of the inner cavity of the anchor plate body and is fixedly connected to the upper end of the third grinding section.

[0015] The second right-angled edge of the second grinding section extends toward the center of the inner cavity of the anchor plate body and is fixedly connected to the upper end of the third grinding section. This connection method tightly combines the second grinding section and the third grinding section together. During the grinding process, it can ensure that the two grinding sections rotate synchronously and that the third grinding section maintains a stable position in the inner cavity of the anchor plate body, so as to uniformly grind the inner wall of the inner cavity and ensure that the inner wall of the anchor plate body can also achieve a high-quality grinding effect.

[0016] As a further optimization of this utility model, a connecting arm is detachably installed on the rotating shaft. The free end of the connecting arm extends horizontally and is equipped with a connecting block. The connecting block is fixedly connected to the grinding part by fasteners, preferably screws.

[0017] The connecting arm and connecting block on the rotating shaft are designed to be detachable, which makes it easy to operate when the grinding parts are worn or when it is necessary to replace the grinding parts with different materials. When the grinding parts are worn to a certain extent and affect the grinding effect, the old grinding parts can be removed and the new grinding parts can be installed simply by loosening the fasteners. This detachable structure reduces the maintenance cost of the equipment, improves the practicality and flexibility of the equipment, and enables the equipment to adapt to different grinding needs.

[0018] As a further optimization of this utility model, the grinding part is a grinding head made of silicon carbide or brown fused alumina. Silicon carbide and brown fused alumina have the characteristics of high hardness and good wear resistance. Using these two materials to make grinding parts can ensure that there is enough grinding force to remove burrs and uneven parts on the surface of the anchor plate when grinding the anchor plate.

[0019] Silicon carbide grinding heads have high grinding efficiency and can quickly perform rough grinding on anchor plates to remove larger imperfections; brown fused alumina grinding heads have good toughness and can make the surface of anchor plates smoother when fine grinding is performed after rough grinding, meeting the strict requirements of anchor plates for flatness and smoothness and improving product quality.

[0020] As a further optimization of this utility model, the equipment also includes a matching positioning fixture. The positioning fixture includes a liftable base, a fixing ring installed at the upper end of the base, and multiple clamps symmetrically distributed in a ring on the upper surface of the fixing ring. The lower end of the anchor plate body is assembled to the upper end of the fixing ring and locked by the multiple clamps.

[0021] A top rod is installed at the lower end of the base. The top rod is installed on the movable end of the lifting machine (such as a cylinder or electric push rod). The lifting machine drives the base to rise and fall. When the base is at a low position, it is convenient for the operator to load and unload the anchor plate body. When the base drives the anchor plate body to move upward, the rotating shaft and the grinding part extend into the inner cavity of the anchor plate body, and the grinding part contacts the surface to be processed, which facilitates precise grinding.

[0022] The fixing ring is used to place the anchor plate body and provide it with a stable placement platform. Multiple clamps arranged in a ring symmetrically can clamp the anchor plate body from multiple directions to ensure that the anchor plate does not shift or shake during the grinding process. This positioning fixture can quickly fix the anchor plate body, ensure the accuracy and stability of grinding, and improve grinding quality and efficiency.

[0023] To improve the placement stability of the anchor plate body, a groove is provided on the upper end face of the fixing ring to match the lower end of the anchor plate body. The lower end of the anchor plate body is directly inserted into the groove to achieve initial positioning, and then it can be clamped by multiple clamps. The clamps can be electric clamps or manual clamps in the prior art.

[0024] As a further optimized solution of this utility model, a stabilizing seat located at the center of the inner ring of the fixing ring is rotatably installed on the upper end face of the base. The upper end face of the stabilizing seat is provided with a slot that matches the lower end of the rotating shaft. The lower end of the rotating shaft passes through the anchor plate body and extends downward and is engaged with the slot.

[0025] The stabilizing seat is installed in the center of the inner ring of the fixed ring. The groove on its upper end face engages with the lower end of the rotating shaft. During the grinding process, the stabilizing seat can support the rotating shaft, ensuring its stability during rotation and preventing it from shaking, thereby improving the grinding accuracy. On the other hand, the stabilizing seat cooperates with the fixed ring to further position the anchor plate body, ensuring that the anchor plate body is accurately positioned during grinding and avoiding uneven grinding caused by the shaking of the rotating shaft or the displacement of the anchor plate.

[0026] As a further optimization of this utility model, a waste discharge channel is provided inside the base. One end of the waste discharge channel is opened on the upper surface of the base and is connected to the inner ring of the fixing ring. The other end of the waste discharge channel is opened on the lower surface of the base.

[0027] During the grinding process, a large amount of debris is generated in the inner cavity of the anchor plate body. The design of the waste discharge channel can discharge these debris in a timely manner. One end is connected to the inner ring of the fixing ring, so that the debris in the inner cavity of the anchor plate body can directly enter the waste discharge channel. The other end opens on the lower end face of the base to facilitate the discharge of debris from the equipment. This can reduce the impact of debris on the grinding quality, prevent debris from accumulating in the anchor plate body and affecting the grinding effect, and also extend the service life of the equipment and facilitate the maintenance and cleaning of the equipment.

[0028] The grinding equipment for processing anchor plates proposed in this utility model has the following beneficial effects:

[0029] (i) By driving the rotating shaft with a motor, the first grinding section, the second grinding section and the third grinding section can be rotated synchronously, thereby grinding the upper end face of the anchor plate body, the inner wall of the assembly groove and the inner wall of the anchor plate body at the same time. Multiple parts can be ground at once, eliminating the need for manual secondary or tertiary grinding, greatly shortening the grinding time, significantly improving grinding efficiency, accelerating the overall processing of the anchor plate, and helping enterprises improve production efficiency.

[0030] (ii) The first grinding section is attached to the upper surface of the anchor plate body to ensure its flatness. The second grinding section is L-shaped and can fit the inner circumference and bottom surface of the assembly groove in all directions to finely grind the assembly groove. The third grinding section is attached to the inner wall of the anchor plate body for grinding. This precise grinding method ensures the grinding quality of each key part of the anchor plate, improves the flatness and smoothness of the product, and ensures the connection effect and installation quality of the anchor plate and the anchor. At the same time, the stable seat of the positioning fixture cooperates with the slot at the lower end of the rotating shaft to ensure the rotation of the rotating shaft while preventing the rotating shaft from shaking, further improving the grinding accuracy and avoiding uneven grinding.

[0031] (iii) The connecting arm and connecting block on the rotating shaft are detachable, making it easy to replace the grinding parts. When the grinding parts are worn or need to be replaced with different materials, they can be quickly disassembled and installed. The operation is convenient and reduces the equipment maintenance cost.

[0032] (iv) The liftable base, fixing ring and multiple clamps can quickly fix the anchor plate body, while the design of the waste discharge channel inside the base facilitates the discharge of processing debris from the inner cavity of the anchor plate body, reduces the impact of debris on the grinding quality, extends the service life of the equipment and facilitates equipment maintenance.

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] In the field of workpiece grinding technology, the grinding quality of anchor plates is crucial to their performance in prestressed concrete structures. Traditional grinding equipment is inefficient and affects the production efficiency of enterprises because it cannot grind multiple parts of the anchor plate at the same time. The grinding equipment for anchor plate processing of this utility model effectively solves these problems through innovative design. The specific implementation method is described below from the design of each component, their mutual cooperation and working process.

[0041] like Figure 1 and Figure 2 As shown, the key to the grinding equipment is the grinding component 3 installed on the rotating shaft 2. It consists of a first grinding section 31, a second grinding section 32, and a third grinding section 33. These three grinding sections are precisely matched with different parts of the anchor plate body 11. By driving the rotating shaft 2 to rotate through the motor 1, multiple surfaces of the anchor plate body 11 can be ground synchronously.

[0042] like Figure 2As shown, the first grinding section 31 corresponds to the upper end face of the anchor plate body 11. Its shape and size design can ensure that the upper end face is ground comprehensively and evenly when the motor 1 drives the rotating shaft 2 to rotate, ensuring the flatness and smoothness of the plane and meeting the high precision requirements of the connection with the anchor.

[0043] The second grinding section 32 is L-shaped with its inner right angle facing upwards. The first right angle side fits tightly against the inner circumferential surface of the assembly groove 12, and the second right angle side presses against the bottom surface of the inner cavity of the assembly groove 12. This unique design allows it to penetrate deep into the assembly groove and grind the circumferential and bottom surfaces simultaneously, effectively removing burrs and uneven parts from the inner wall.

[0044] The third grinding section 33 is set in the inner cavity of the anchor plate body 11, fits against the inner wall, and grinds the inside of the anchor plate body 11 to improve the smoothness of the inner cavity.

[0045] The first grinding section 31 and the third grinding section 33 are fixedly connected by the second grinding section 32 to form a whole. They rotate synchronously under the drive of the rotating shaft 2 to achieve grinding of multiple parts at one time, breaking through the limitations of traditional grinding equipment.

[0046] like Figure 1 and Figure 2 As shown, the rotating shaft 2 is fixed to the grinding part 3 by a detachable connecting arm 4 and a connecting block 5. The fastener is preferably a screw. This detachable design brings great convenience to the maintenance and upgrading of the equipment.

[0047] like Figure 1 As shown, the outer circumferential surface of the rotating shaft 2 has external threads, and the end of the connecting arm 4 away from the connecting block 5 has a sleeve hole that is adapted to the rotating shaft 2. The connecting arm 4 is slidably fitted onto the rotating shaft 2 through the sleeve hole and is fastened by nuts. There are two nuts, which are respectively set at the upper and lower ends of the connecting arm 4. The connecting arm 4 can be fixed by the engagement of the nuts with the threads of the rotating shaft 2. This not only enables quick disassembly and assembly of the connecting arm 4, but also allows the height of the connecting arm 4 to be adjusted according to the actual use, thereby adjusting the height of the grinding part 3.

[0048] When the grinding part 3 wears down due to prolonged use and affects the grinding effect, the operator can easily remove the old grinding part and install the new one simply by loosening the screws.

[0049] Grinding part 3 is made of silicon carbide or brown fused alumina. Silicon carbide has high hardness and high grinding efficiency, making it suitable for rough grinding of anchor plates and quickly removing larger surface defects. Brown fused alumina has good toughness and is used for subsequent fine grinding, which can make the surface of the anchor plate smoother, meet the strict requirements of flatness and smoothness of the product, and ensure product quality.

[0050] like Figure 2As shown, the grinding equipment is equipped with positioning fixtures, which mainly consist of a liftable base 6, a fixing ring 7 and multiple clamps 8. The lower end of the base 6 is equipped with a top rod, which is connected to the movable end of the lifting mechanism such as a cylinder or electric push rod.

[0051] During operation, the elevator drives the base 6 to rise and fall. When the base 6 is in a low position, it is convenient for the operator to place and take out the anchor plate body 11. When the base 6 rises, the anchor plate body 11 moves accordingly. At this time, the rotating shaft 2 and the grinding part 3 can extend into the inner cavity of the anchor plate body 11 and make the grinding part 3 accurately contact the surface to be processed, creating conditions for precise grinding.

[0052] The fixing ring 7 is installed on the upper end of the base 6. The upper end face of the fixing ring 7 is provided with a groove that is adapted to the lower end of the anchor plate body 11. The lower end of the anchor plate body 11 can be directly inserted into the groove to achieve initial positioning. Multiple clamps 8 arranged in a ring symmetrically are installed on the upper end face of the fixing ring 7. These clamps can be electric clamps or manual clamps, etc. They clamp the anchor plate body 11 from multiple directions to ensure that the anchor plate will not be displaced or shaken during the grinding process, thus ensuring high precision grinding.

[0053] In addition, a stabilizing seat 9 is rotatably installed on the upper end face of the base 6 at the center of the inner ring of the fixing ring 7. The upper end face of the stabilizing seat 9 is provided with a slot that matches the lower end of the rotating shaft 2. During grinding, the lower end of the rotating shaft 2 passes through the anchor plate body 11 and is engaged with the slot.

[0054] The stabilizing seat 9 serves a dual purpose: on the one hand, it supports the rotating shaft 2, ensuring its stability during high-speed rotation and preventing wobbling, thereby improving grinding accuracy; on the other hand, it works in conjunction with the fixing ring 7 to further position the anchor plate body 11, ensuring that the anchor plate maintains an accurate position during the grinding process and avoiding uneven grinding caused by shaft wobbling or anchor plate displacement.

[0055] like Figure 2 As shown, a waste discharge channel 10 is provided inside the base 6. One end of the channel is connected to the inner ring of the fixing ring 7, and the other end is located on the lower end face of the base 6. During the grinding process, a large amount of debris will be generated in the inner cavity of the anchor plate body 11. If these debris are not discharged in time, they will accumulate in the anchor plate, which will not only affect the grinding effect, but may also scratch the ground surface. It will also increase the wear of the equipment and shorten the service life of the equipment. The design of the waste discharge channel 10 cleverly solves this problem. The debris can directly enter the waste discharge channel 10 from the inner ring of the fixing ring 7 and be discharged from the lower end face of the base 6. This effectively reduces the impact of debris on the grinding quality, facilitates the maintenance and cleaning of the equipment, and extends the service life of the equipment.

[0056] It should be noted that the grinding debris on the upper surface of the anchor plate body 11 and in the inner cavity of the assembly groove 12 can be treated by equipment such as air gun, blower or vacuum cleaner, which will not be elaborated here.

[0057] In actual use, first place the anchor plate body 11 on the fixing ring 7, insert its lower end into the groove for initial positioning, then clamp and fix it with the clamp 8, start the elevator, raise the base 6, and drive the anchor plate body 11 to move up until the grinding part 3 and the surface to be processed of the anchor plate body 11 are in accurate contact.

[0058] Then start motor 1, motor 1 drives shaft 2 to rotate, driving the first grinding section 31, the second grinding section 32 and the third grinding section 33 of grinding part 3 to rotate synchronously. The first grinding section 31 grinds the upper end surface of the anchor plate body 11, the second grinding section 32 grinds the inner wall and bottom surface of the assembly groove 12, and the third grinding section 33 grinds the inner wall of the anchor plate body 11.

[0059] During the grinding process, the debris generated is discharged in time through the waste discharge channel 10. After grinding is completed, the motor 1 is turned off, the base 6 is lowered, the clamp 8 is loosened, and the ground anchor plate body 11 is taken out. If the grinding part 3 is worn, a new grinding part 3 can be replaced by removing the screws on the connecting arm 4 and the connecting block 5 so that the next grinding work can be carried out.

[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
