DETAILED DESCRIPTION

[0048] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0049] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0050] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0051] Example 1

[0052] Reference Figure 1 to Figure 3, which is the first embodiment of the present invention, provides an external cylindrical grinder with an easy-to-replace grinding wheel, which includes a support unit 1, including a base 11, a pressure plate 12 arranged at the end of the base 11, a clamping member 14 arranged on the inner side of the pressure plate 12, a reset member 13 that abuts against the end of the clamping member 14, a fixing sleeve 15 arranged at the end of the pressure plate 12, and a pressure rod member 16 passing through the inner side of the fixing sleeve 15.

[0053] In this embodiment, the base 11 and the pressure plate 12 cooperate to fix the grinding wheel on the outside of the rod of the base 11; thereby, a good support is provided for the grinding wheel. The clamping member 14 is provided to clamp the transmission shaft and the pressure plate 12, thereby ensuring that the base 11 is fixed on the outside of the transmission shaft, and the transmission shaft can drive the grinding wheel to rotate synchronously.

[0054] The base 11 includes a bottom support plate and a guide column. During the installation of the grinding wheel, the bottom support plate of the base 11 is placed horizontally on the ground, and then the grinding wheel is put on the outside of the guide column, and then the pressure plate 12 is buckled on the other side of the grinding wheel, so that the pressure plate 12 is close to the grinding wheel and connected to the base 11, so that the grinding wheel can be fixed by cooperating between the base 11 and the pressure plate 12.

[0055] Furthermore, the support shaft 3 includes a rod portion 31 and a cone 32 disposed outside the rod portion 31 ; a grinding wheel N is installed between the pressure plate 12 and the base 11 , and the cone 32 penetrates the base 11 and extends into the interior thereof.

[0056] The rod portion 31 is a hollow rod-shaped structure, and the cone 32 is arranged outside the rod portion 31; the rod portion 31 and the cone 32 are fixed by a key connection.

[0057] It should be noted that the outer side of the cone 32 is a conical frustum structure, and the inner side of the base 11 corresponding to it is provided with a mounting groove adapted to the cone 32; during the installation process, the base 11 is sleeved on the outer side of the cone 32. During the installation process, the end face of the pressure plate 12 is squeezed by the clamping member 14, so that the base 11 moves toward the direction close to the cone 32, thereby achieving a close fixation between the base 11 and the cone 32.

[0058] Preferably, the fixing sleeve 15 is sleeved on one side of the end surface of the pressure plate 12 , and the fixing sleeve 15 provides certain support for the spiral feeding of the pressure rod 16 , and can ensure that the pressure rod 16 can move along the axial direction of the fixing sleeve 15 .

[0059] Specifically, the pressure rod 16 is connected to the clamping member 14. When the pressure rod 16 rotates, the clamping member 14 can be driven to rotate, so that the rotation of the pressure rod 16 can drive the clamping member 14 to separate from the reset member 13, thereby releasing the tight connection between the base 11 and the cone 32, and then the base 11 can be removed from the cone 32, thereby completing the disassembly of the grinding wheel.

[0060] In summary, the present invention makes the disassembly process of the grinding wheel extremely simple and efficient through the cooperation between the pressure rod and the clamping member; the operator only needs to use a single tool to successfully complete the disassembly of the grinding wheel, which not only reduces the required operating steps but also significantly improves work efficiency.

[0061] Example 2

[0062] Reference Figure 1 to Figure 7 , which is the second embodiment of the present invention, and is different from the first embodiment in that: it also includes: the base 11 includes a bottom plate 111, and a sleeve rod 112 arranged at the end of the bottom plate 111; the sleeve rod 112 penetrates the grinding wheel N and extends to the outside thereof; the pressure plate 12 includes a connecting sleeve 121 arranged at its end; the inner wall of the connecting sleeve 121 conflicts with the end of the sleeve rod 112, and the connecting sleeve 121 is connected to the sleeve rod 112.

[0063] In this embodiment, the base plate 111 is a circular structure, and a sleeve rod 112 is integrally formed at the end surface of the base plate 111; the sleeve rod 112 is a cylindrical structure, and the sleeve rod 112 can support the grinding wheel. During the installation process, the grinding wheel can be sleeved on the outside of the sleeve rod 112.

[0064] It should be noted that the pressure plate 12 is integrally formed with a connecting sleeve 121 on the outer side of its end, and the connecting sleeve 121 protrudes from the end face of the pressure plate 12 and is located inside it to form a movable depression; when the pressure plate 12 is tightly attached to the grinding wheel, the inner wall of the connecting sleeve 121 contacts the end of the sleeve rod 112, and then the bolts penetrate the connecting sleeve 121 and the screw holes opened in the end of the sleeve rod 112 to threadably cooperate with each other, thereby achieving the fixing of the sleeve rod 112 and the connecting sleeve 121 by threaded connection.

[0065] Furthermore, the sleeve rod 112 includes a tapered hole 1121 formed therein; the tapered hole 1121 is adapted to the cone 32 , and the inner wall of the tapered hole 1121 is in conflict with the outer wall of the cone 32 .

[0066] It should be noted that a tapered hole 1121 is provided inside the sleeve rod 112, and the bottom of the tapered hole 1121 passes through the bottom plate 111 and extends outward; the tapered hole 1121 is adapted to the cone 32, and when the outer wall of the cone 32 is pressed against the inner wall of the tapered hole 1121, a stable connection can be achieved between the base 11 and the cone 32; during the installation process, when the sleeve rod 112 moves toward the cone 32, the end with a smaller inner diameter of the tapered hole 1121 gradually approaches the end with a larger outer diameter of the cone 32, thereby making it possible to make the sleeve rod 112 and the cone 32 fit tightly.

[0067] Furthermore, the clamping member 14 includes an internal threaded sleeve 141 and a fixed rod 142 arranged inside the internal threaded sleeve 141; the rod portion 31 includes a first external threaded portion 311 arranged at its end; the internal threaded sleeve 141 is adapted to the first external threaded portion 311; the pressure plate 12 also includes an external threaded sleeve rod 122 arranged at the end of the connecting sleeve 121; the end of the internal threaded sleeve 141 and the end of the external threaded sleeve rod 122 can conflict with each other, thereby achieving a close fit between the tapered hole 1121 and the cone 32.

[0068] It should be noted that the fixing rod 142 is arranged at the center position of the internal threaded sleeve 141, and the fixing rod 142 is a tubular structure with a hollow interior; the internal threaded sleeve 141 is threadedly connected to the first external threaded portion 311, and the fixing rod 142 penetrates the rod portion 31 and extends to the interior thereof, and the outer wall of the fixing rod 142 conflicts with the inner wall of the rod portion 31; through the cooperation between the fixing rod 142 and the rod portion 31, a certain guiding role can be played, so that the moving direction of the clamping member 14 can move along the axial direction of the rod portion 31.

[0069] Specifically, an externally threaded sleeve rod 122 is provided at the end surface of the connecting sleeve 121, and the externally threaded sleeve rod 122 protrudes from the surface of the connecting sleeve 121; the internally threaded sleeve 141 is threadedly matched with the first externally threaded portion 311. When the internally threaded sleeve 141 is rotated and spirally fed along the axial direction of the rod portion 31, the end of the internally threaded sleeve 141 can be in conflict with the end surface of the externally threaded sleeve rod 122, and then the base 11 and the cone 32 can be pressed and fixed through the threaded match between the internally threaded sleeve 141 and the first externally threaded portion 311.

[0070] Furthermore, the fixing sleeve 15 includes a first internal threaded portion 151 disposed on the inner wall of the opening end thereof; the first internal threaded portion 151 is adapted to the external threaded sleeve rod 122; and the fixing rod 142 penetrates the bottom plate 111 and extends to the inside thereof.

[0071] It should be noted that the fixing sleeve 15 is provided with a first internal threaded portion 151 on the inner side of its open end, and the first internal threaded portion 151 is threadedly connected to the external threaded sleeve rod 122; during the installation process, the fixing sleeve 15 and the external threaded sleeve rod 122 are fixed by bolt connection.

[0072] Furthermore, the fixing sleeve 15 also includes a threaded hole 152 passing through its end face; the pressure rod 16 includes a push rod 161; a second external threaded portion 1611 is provided on the outer side of the end of the push rod 161; the second external threaded portion 1611 is adapted to the threaded hole 152, and the push rod 161 passes through the threaded hole 152 and extends to the inner side of the fixing sleeve 15.

[0073] It should be noted that a threaded hole 152 is also provided on the end face of the fixing sleeve 15, and the threaded hole 152 is coaxially arranged with the fixing sleeve 15; the pressure rod 16 is a rod-shaped structure, and one end of the pressure rod 16 passes through the threaded hole 152 and extends to the outside thereof; the pressure rod 16 is also provided with a hexagonal bolt head near the outside of the end of the fixing sleeve 15, so that the staff can use tools to drive the pressure rod 16 to rotate.

[0074] Specifically, a second external threaded portion 1611 is further provided on the outer side of the push rod 161, and the second external threaded portion 1611 is threadedly matched with the threaded hole 152. The push rod 161 rotates so that the second external threaded portion 1611 moves along the axial direction of the threaded hole 152; the push rod 161 is a right-handed thread structure, and the threaded hole 152 is also a right-handed thread structure.

[0075] Furthermore, a slider 162 is provided on the outer wall of the push rod 161; a slide groove 1421 is provided inside the fixed rod 142; the end of the push rod 161 extends to the inside of the fixed rod 142; the slide groove 1421 is adapted to the slider 162, thereby realizing synchronous rotation of the pressure rod 16 and the clamping member 14.

[0076] In this embodiment, a slider 162 is provided on the outer wall of the push rod 161, and the slider 162 is located inside the slide groove 1421, and the slide groove 1421 can limit the slider 162; when the pressure rod 16 rotates, it can drive the slider 162 to squeeze the inner wall of the slide groove 1421, so that the rotation of the pressure rod 16 can drive the clamping member 14 to rotate.

[0077] It should be noted that the push rod 161 penetrates the inner side of the fixed rod 142, and the length of the push rod 161 can ensure that the pressure rod 16 will not separate from the fixed rod 142 during movement, so that the slider 162 is always located inside the slide groove 1421, thereby realizing the linkage between the pressure rod 16 and the clamping member 14.

[0078] Furthermore, the second external thread portion 1611 and the first external thread portion 311 have opposite thread rotation directions; the pressure rod 16 moves toward the first external thread portion 311 , thereby driving the internal thread sleeve 141 to move away from the first external thread portion 311 .

[0079] In this embodiment, the second external threaded portion 1611 is a right-handed thread structure, and the first external threaded portion 311 is a left-handed thread structure; when the second external threaded portion 1611 rotates and approaches the first external threaded portion 311 in the process of spiral feeding, the clamping piece 14 also rotates synchronously with the pressure rod 16; as the clamping piece 14 rotates, the clamping piece 14 moves toward the direction approaching the threaded hole 152; thereby, in the process of rotating the pressure rod 16, the end face of the clamping piece 14 can be driven away from the end face of the external threaded sleeve rod 122, and then can contact the internal threaded sleeve 141 to limit the external threaded sleeve rod 122, thereby providing a certain space for the sleeve rod 112 to be movable outside the cone 32.

[0080] Furthermore, a fixing block 33 is also provided inside the rod portion 31; the rod portion 31 and the fixing block 33 are fixedly connected; one end of the reset member 13 is in conflict with the inner wall of the fixing sleeve 15, and the other end thereof is in conflict with the end face of the internal threaded sleeve 141; the pressing rod member 16 moves toward the direction approaching the first external threaded portion 311, thereby enabling the internal threaded sleeve 141 to be separated from the first external threaded portion 311, and the end of the pressing rod member 16 can be in conflict with the end face of the fixing block 33.

[0081] In this embodiment, the fixing block 33 is arranged inside the rod portion 31, and the position between the fixing block 33 and the rod portion 31 is relatively fixed, and the fixing block 33 and the rod portion 31 are fixed by interference fit; with the continuous rotation of the pressure rod 16, the end of the push rod 161 gradually approaches the fixing block 33, and at the same time, the internal threaded sleeve 141 is also separated from the first external threaded portion 311 as the pressure rod 16 rotates; during the movement, the end face of the internal threaded sleeve 141 squeezes the reset member 13, so that the reset member 13 is in a compressed state.

[0082] Specifically, the reset member 13 is preferably a spring. The elastic potential energy released by the reset member 13 can make the end face of the internal threaded sleeve 141 close to the end face of the first external threaded portion 311, thereby providing appropriate force for tightening the threads between the internal threaded sleeve 141 and the first external threaded portion 311, ensuring that the threaded connection can be accurately matched.

[0083] When the internal threaded sleeve 141 and the first external threaded portion 311 are separated, the rotation of the pressure rod 16 will synchronously drive the clamping member 14 to rotate, but the clamping member 14 no longer moves along the axial direction of the first external threaded portion 311; at this time, the reset member 13 releases its elastic potential energy to push the internal threaded sleeve 141 to fit tightly against the end position of the first external threaded portion 311; and through the cooperation between the set fixing rod 142 and the inner wall of the rod portion 31, the axial position between the internal threaded sleeve 141 and the first external threaded portion 311 coincides, thereby better facilitating the control of tightening the threaded connection between the internal threaded sleeve 141 and the first external threaded portion 311.

[0084] As the pressure rod 16 is continuously advanced, when the end face of the push rod 161 conflicts with the fixed block 33, the movement of the pressure rod 16 along the axial direction of the threaded hole 152 is restricted. At this time, the push rod 161 continues to be rotated and is limited by the fixed block 33. While the push rod 161 rotates, it drives the fixed sleeve 15 to move along the axial direction of the push rod 161, so that the fixed sleeve 15 pulls the pressure plate 12 to move, and then the pressure plate 12 drives the base 11 to move, so that the tapered hole 1121 moves away from the cone 32, so that a gap is generated between the tapered hole 1121 and the cone 32, so that the base 11 can be removed from the outside of the cone 32.

[0085] Furthermore, the protection unit 2 includes a protection cover 21 and a baffle 22 disposed on a side wall of the protection cover 21 ; the rod portion 31 penetrates the protection cover 21 and extends to the outside thereof.

[0086] It should be noted that the protective cover 21 is cast using stamping technology and is a metal thin plate structure; one side of the protective cover 21 is an open end, and the baffle 22 is fixedly connected to the protective cover 21 by bolt connection; the protective cover 21 is installed on the external cylindrical grinder M, and the rod 31 is connected to the drive setting of the external cylindrical grinder M.

[0087] The rod 31 passes through the protective cover 21 and extends to the inside thereof, and the cone 32 is located inside the protective cover 21. The protective cover 21 surrounds the outside of the grinding wheel while leaving an opening on one side so that the grinding wheel can grind the parts; the protective cover 21 can effectively prevent debris from splashing during the grinding process.

[0088] When in use, when the staff needs to disassemble the grinding wheel, the staff first uses a tool to disassemble the baffle 22 from one side of the protective cover 21, and then puts a spanner on the outside of the hexagonal head set at the end of the pressure rod 16; then the spanner is turned to drive the pressure rod 16 to rotate, so that the pressure rod 16 can rotate along the inside of the threaded hole 152 and move along the axial direction of the threaded hole 152, and the push rod 161 moves in the direction close to the fixed block 33. When the push rod 161 rotates, it drives the clamping piece 14 to rotate, so that the clamping piece 14 moves in the direction close to the threaded hole 152; thereby, the end of the internal threaded sleeve 141 no longer conflicts with the end face of the external threaded sleeve rod 122; thereby, the limit of the internal threaded sleeve 141 on the external threaded sleeve rod 122 can be released, so that the base 11 provides a certain space for movement; as the pressure rod 16 continues to rotate, the internal threaded sleeve 141 and the first external threaded portion 311 are separated; then the pressure rod 16 continues to rotate, so that the end of the push rod 161 conflicts with the fixed block 33, and when the push rod 161 is limited by the fixed block 33, the push rod 161 no longer moves along the axial direction of the rod portion 31; the rotation of the push rod 161 can drive the fixed sleeve 15 to move along the axial direction of the push rod 161, so that the fixed sleeve 15 moves away from the rod portion 31, and then the fixed sleeve 15 pulls the pressure plate 12 to move, so that the pressure plate 12 drives the base 11 connected thereto to move, thereby generating a certain gap between the tapered hole 1121 and the cone 32, and then the disassembly of the grinding wheel can be completed.

[0089] During the installation process, the grinding wheel is first installed between the pressure plate 12 and the base 11 and fixed, and then the base 11 is sleeved on the outside of the cone 32; then the slider 162 is inserted into the inner side of the slide groove 1421, and at the same time, the push rod 161 passes through the inside of the fixed rod 142; then the fixed rod 142 is inserted into the inner side of the rod portion 31, so that the internal thread sleeve 141 can only move along the axial direction of the rod portion 31, and then the fixed sleeve 15 is sleeved on the outside of the external thread sleeve rod 122, and the fixed sleeve 15 is fixed by the threaded fit between the first internal thread portion 151 and the external thread sleeve rod 122. The sleeve 15 is connected to the external threaded sleeve rod 122, and then the pressure rod 16 is turned over and rotated, so that the pressure rod 16 drives the clamping member 14 to be spirally fed toward the fixed block 33, so that the internal threaded sleeve 141 can gradually approach the end of the external threaded sleeve rod 122; during the movement of the internal threaded sleeve 141, it continuously pushes the base 11 connected to the pressure plate 12 to move toward the direction of the cone 32 until the inner wall of the tapered hole 1121 conflicts with the outer wall of the cone 32, so that the position between the base 11 and the cone 32 is fixed, thereby realizing the installation of the grinding wheel.

[0090] In summary, the device significantly accelerates the grinding wheel disassembly process by optimizing the cooperation between the pressure rod and the clamping member, thereby greatly reducing the workload of the staff; in traditional methods, the disassembly and installation of the grinding wheel often require multiple tools and go through multiple complex steps, which is not only time-consuming but also easily leads to fatigue and increased stress on the operator; in contrast, the device allows the operator to complete the entire disassembly process using only a single tool, simplifying the operating process and shortening the time required.

[0091] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
