Abstract
Description
A guide clamp Technical Field
[0001] This utility model belongs to the field of clamping technology and relates to a guide clamp. Background Technology
[0002] In the field of circular abrasive manufacturing, it is often necessary to attach particles, such as metal or resin particles, along the circumferential direction at the outer edge of one end of the circular abrasive to achieve the grinding function. This is done manually by applying glue and attaching the particles one by one, arranging the arc-shaped particles along the circular edge of the abrasive. Adjacent particles must maintain the same spacing, and the arc direction of the particles must be consistent with the arc of the abrasive edge. However, this method has significant drawbacks: firstly, the lack of precise positioning guidance structures during manual operation makes it difficult to control the spacing between particles, resulting in uneven spacing and uneven circumferential distribution of particles; secondly, because the edge of the circular abrasive is arc-shaped, the particles must be strictly aligned with the arc direction of the edge, but manual operation is prone to visual deviations or hand tremors, causing the particle installation direction to deviate, affecting the grinding accuracy and performance of the circular abrasive.
[0003] While existing automated equipment can achieve more precise granule application, it uses robotic arms to pick up or adsorb granules, resulting in high equipment costs and large footprints. Summary of the Invention
[0004] The purpose of this invention is to provide a guide clamp that solves the problem of low accuracy caused by the lack of a guide device when particles need to be pasted on the end of a circular mold in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a guide clamp, comprising a clamp body for mounting on a circular grinding mold, the clamp body having a plurality of circumferentially distributed material distribution grooves, the interval between two adjacent material distribution grooves being equal, the material distribution grooves being arc-shaped grooves for loading matching arc-shaped particles; and after the clamp body is mounted on the circular grinding mold, the arc-shaped grooves are located at the edge of the circular grinding mold, and the arc direction of the arc-shaped grooves is consistent with the contour direction of the edge of the circular grinding mold.
[0006] Optionally, the fixture body includes an outer ring, an inner ring, and connectors. The inner ring is coaxially placed inside the outer ring. The connectors are located in the annular gap between the inner and outer rings. There are multiple connectors and they are evenly distributed along the circumference of the inner ring. Each connector connects the inner ring and the outer ring. A material distribution groove is formed between two adjacent connectors.
[0007] Optionally, the upper end face of the inner ring is flush with the upper end face of the outer ring, and the lower end face of the inner ring protrudes downward relative to the lower end face of the outer ring. The protruding end of the inner ring relative to the outer ring is used to engage with the inner surface of the inner protrusion on the top surface of the circular mold.
[0008] Optionally, the connector extends radially along the inner ring.
[0009] Optionally, the connector includes a connecting block, one end of which is welded to the inner ring and the other end of which is welded to the outer ring; or, the connecting block is integrally formed with the inner ring and the outer ring.
[0010] Optionally, the circumferential dimension of the material distribution groove along the inner ring is 22mm-23mm.
[0011] Optionally, the number of material distribution troughs is 25-35.
[0012] The beneficial effects of this utility model are as follows: This utility model provides a guide clamp with equally spaced arc-shaped material distribution grooves evenly distributed around the circumference of the clamp body. This allows for precise positioning of the arc-shaped particles that need to be bonded, ensuring that the particles are strictly aligned with the arc of the edge of the circular mold, and that the particles are evenly distributed.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0025] In related technologies, as shown in Figure 3, the top surface of a circular abrasive 2 used for grinding typically has two annular protrusions. One annular protrusion is located at the edge of the end face of the circular abrasive 2 and is designated as an outer protrusion 22. The other annular protrusion is located inside the outer protrusion 22 and is designated as an inner protrusion 21. A groove 23 for placing arc-shaped particles is formed between the inner protrusion 21 and the outer protrusion 22.
[0026] As shown in Figures 1-4, this utility model provides a guide clamp 1, including a clamp body 10 for mounting on a circular grinding mold 2. The clamp body 10 is provided with a plurality of circumferentially distributed material distribution grooves 11, the interval between two adjacent material distribution grooves 11 is equal, and the material distribution grooves 11 are arc-shaped grooves 110 for loading matching arc-shaped particles. After the clamp body 10 is mounted on the circular grinding mold 2, the arc-shaped grooves 110 are located at the edge of the circular grinding mold 2, and the arc direction of the arc-shaped grooves 110 is consistent with the contour direction of the edge of the circular grinding mold 2.
[0027] Specifically, the shape of the fixture body 10 is not limited and can be circular, square or any other shape. The fixture body 10 is installed after the circular grinding mold 2. Multiple material distribution grooves 11 are distributed equidistantly along the edge circumference of the circular grinding mold 2. The material distribution grooves 11 are arc-shaped grooves 110, and the arc direction is consistent with the contour direction of the edge of the circular grinding mold 2. That is, the arc center of the arc-shaped groove 110 is concentric with the center of the circular grinding mold 2.
[0028] Therefore, after the fixture body 10 is installed on the circular abrasive mold 2, the distribution groove 11 serves as a guide structure. The operator can place the arc-shaped particles one by one into each distribution groove 11. The distribution groove 11 provides precise matching and positioning for the corresponding particles. Since the interval between two adjacent distribution grooves 11 is equal, the gap between adjacent particles is consistent when the particles are arranged in each distribution groove 11, resulting in a more uniform distribution of particles along the circumferential direction. On the other hand, since the arc direction of the distribution groove 11 is consistent with the contour direction of the edge of the circular abrasive mold 2, the arc-shaped particles in the distribution groove 11 will naturally and strictly align with the arc direction of the edge of the circular abrasive mold 2. This avoids the need for manual visual observation to precisely place the particles, making the operation of aligning and pasting particles on the circular abrasive mold 2 easier. At the same time, it avoids the deviation of the particle installation direction due to visual bias or hand tremors during manual operation, ensuring the grinding accuracy and performance of the circular abrasive mold 2 after the particles are pasted. In addition, compared with existing automated equipment such as robotic arms or vacuum suction cups, the guide fixture of this application has a smaller overall size and occupies less space. At the same time, the structure of the guide fixture 1 is also relatively simple, and the manufacturing cost is low, making it suitable for mass production by small and medium-sized enterprises.
[0029] In some embodiments, the clamp body 10 includes an outer ring 13, an inner ring 12, and a connector 14. The inner ring 12 is coaxially disposed inside the outer ring 13. The connector 14 is disposed in the annular gap between the inner ring 12 and the outer ring 13. There are multiple connectors 14 and they are evenly distributed along the circumference of the inner ring 12. Each connector 14 connects the inner ring 12 and the outer ring 13. A material distribution groove 11 is formed between two adjacent connectors 14.
[0030] Specifically, referring to Figure 1, the diameter of the inner ring 12 is smaller than that of the outer ring 13. The inner ring 12 and the outer ring 13 are coaxial, and the inner ring 12 is located inside the outer ring 13. One end of the connector 14 is welded to the inner ring 12, and the other end of the connector 14 is welded to the outer ring 13. Alternatively, both ends of the connector 14 are integrally formed with the inner ring 12 and the outer ring 13, respectively. An arc-shaped gap is formed between two adjacent connectors 14, which is the aforementioned material distribution groove 11.
[0031] Since the connectors 14 are evenly distributed, that is, adjacent connectors 14 are equidistant, the resulting distribution grooves 11 are also equidistant. These distribution grooves 11 serve as guiding spaces when pasting particles. In use, the guide clamp 1 is installed on the circular mold 2. The gap between the inner ring 12 and the outer ring 13 coincides with the groove 40 in the circular mold 2 where the particles need to be pasted. The particles are placed in the groove of the circular mold 2 along the arc-shaped distribution grooves 11. Under the guidance and positional constraint of each distribution groove 11, multiple particles are evenly and stably placed at the top edge of the circular mold 2. Then, the particles are pressed down and pasted firmly.
[0032] In some embodiments, the upper end face of the inner ring 12 is flush with the upper end face of the outer ring 13, and the lower end face of the inner ring 12 protrudes downward relative to the lower end face of the outer ring 13. The protruding end of the inner ring 12 relative to the outer ring 13 is used to engage with the inner surface of the inner protrusion 21 on the top surface of the circular mold 2.
[0033] Specifically, referring to Figures 2 and 3, the lower end faces of the outer ring 13 and the inner ring 12 are not on the same horizontal plane. The lower end face of the inner ring 12 protrudes downwards compared to the lower end face of the outer ring 13. It can be understood that the protruding end of the inner ring 12 compared to the outer ring 13 is also ring-shaped, and the outer diameter of the protruding end is approximately equal to the inner diameter of the inner protrusion 21. Thus, when the clamp body 10 is fastened to the circular mold 2, the outer circumferential surface of the protruding end of the inner ring 12 can be engaged with the inner surface of the inner protrusion 21.
[0034] Thus, the fixture body 10 and the circular mold 2 can achieve relatively stable installation through their own structure and shape. The fixture body 10 will not easily fall off or move radially when installed on the circular mold 2, which can ensure the accuracy of particle adhesion.
[0035] In some embodiments, the connector 14 extends radially along the inner ring 12.
[0036] Specifically, referring to Figures 2 and 3, the connector 14 extends radially along the inner ring 12, meaning that the extension direction of the connector 140 passes through the center of the inner ring 12. Since the centers of the inner ring 12, outer ring 13, and circular grinding mold 2 coincide when the fixture body 10 and the circular grinding mold 2 are in working condition, the axes of multiple connectors 14 pass through the centers of the inner ring 12, outer ring 13, and circular grinding mold 2. This makes each connector 14 perpendicular to the tangent of the inner ring 12 at one end and perpendicular to the tangent of the outer ring 13 at the other end. As a result, the gap between two connected connectors 14 is arc-shaped, which can form the above-mentioned material distribution groove 11, so that it matches the arc-shaped particles.
[0037] Therefore, when the fixture body 10 and the circular mold 2 are installed, the radial pressure of the connector 14 can be transmitted to the inner ring 12 and the outer ring 13 without displacement; moreover, the distance between two adjacent connectors 14 is equal, so that the size and shape of each of the formed material distribution grooves 11 are the same.
[0038] In some embodiments, the connector 14 includes a connecting block 140, one end of which is welded to the inner ring 12 and the other end of which is welded to the outer ring 13; or, the connecting block 140 is integrally formed with the inner ring 12 and the outer ring 13.
[0039] Specifically, as shown in Figure 2, one end of the connecting block 140 is welded to the inner ring 12, and the other end is welded to the outer ring 13. This connection method is very strong, and the welding process is relatively simple, requiring no high-precision equipment and resulting in low manufacturing costs.
[0040] In other embodiments, the connector 14 can be cylindrical, frustum-shaped, or other shapes. The connector 14 can be integrally formed with the inner ring 12 and the outer ring 13 or connected in other ways. This embodiment is not limited to this.
[0041] In some embodiments, the circumferential dimension of the dispensing trough 11 along the inner ring 12 is 22mm-23mm.
[0042] Specifically, referring to Figure 3, the arrow L in the figure indicates the circumferential length of the material distribution groove 11 along the inner ring 12. The circumferential length of the material distribution groove 11 along the inner ring 12 ranges from 22mm to 23mm, and can be 22.00mm or 23.00mm. In the embodiment shown in Figure 2, the circumferential length of the material distribution groove 11 along the inner ring 12 is preferably 22.26mm.
[0043] The size of 22.26mm makes the material distribution groove 11 a moderate size, which not only ensures the adaptation and guiding effect of the material distribution groove 11 to the arc-shaped particles, but also allows the number of material distribution grooves 11 to be kept within an appropriate range, making it convenient to paste multiple particles.
[0044] In some embodiments, the number of dispensing troughs 11 ranges from 25 to 35.
[0045] Specifically, referring to Figures 1 and 2, the number of material distribution troughs 11 ranges from 25 to 35. For example, if the number of material distribution troughs 11 is 25 or 35, in the embodiment shown in Figure 1, the number of material distribution troughs 11 is preferably 30.
[0046] Depending on the size and distribution of the particles to be adhered, the number and size of the distributing troughs 11 can be changed by altering the number and size of the connectors 14. This method is low in cost and easy to implement.
[0047] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
