[0029] Embodiment 1
[0030] Reference Figures 1-7 For the first embodiment of the utility model, this embodiment provides a grinding machine for diamond grinding wheel production, grinding machine for diamond grinding wheel production includes main part assembly 100, including work table 101, power mechanism 102, rotating mechanism 103 and grinding wheel 104, power mechanism 102 is located on work table 101, rotating mechanism 103 is set up in power mechanism 102 side, and grinding wheel 104 is located in rotating mechanism 103 side.
[0031] Power mechanism 102 is used to drive rotating mechanism 103 to rotate, and rotating mechanism 103 rotates to drive grinding wheel 104 to rotate synchronously, which is prior art, and the present scheme will not be described in detail, and the working principle can be clearly understood by those skilled in the art, and the main component of grinding wheel 104 is diamond abrasive grain.
[0032] Clamping assembly 200 is set up in rotating mechanism 103 side, and includes clamping piece 201, clamping piece 201 includes fixed column 201a, extrusion block 201b, connecting column 201c, moving column 201d and expansion block 201e, fixed column 201a is located in rotating mechanism 103 side, and first moving groove 201a-1 is formed in fixed column 201a, extrusion block 201b slides in first moving groove 201a-1, connecting column 201c fixes one end of extrusion block 201b, second moving groove 201a-2 is formed in fixed column 201a, moving column 201d slides in second moving groove 201a-2, one end of connecting column 201c is fixed with one end of moving column 201d, sliding slot 201a-3 is formed in fixed column 201a, expansion block 201e slides in sliding slot 201a-3, and stress groove 201e-1 is formed in expansion block 201e, and inclined groove 201d-1 is formed on moving column 201d, and inclined groove 201d-1 is attached with stress groove 201e-1.
[0033] Clamping piece 201 is used to connect rotating mechanism 103 and grinding wheel 104, so that rotating mechanism 103 can drive grinding wheel 104 to rotate synchronously.
[0034] When extrusion block 201b is moved to the direction of moving column 201d, extrusion block 201b will drive extrusion block 201b and moving column 201d to move synchronously, and extrusion block 201b will extrude expansion block 201e, and expansion block 201e will move away from connecting column 201c, so as to expand along sliding slot 201a-3 to the outside of fixed column 201a, so as to adapt to the grinding wheel 104 with different inner diameter sizes, and the clamping is completed by the action of friction.
[0035] The clamping assembly 200 further comprises a locking member 202 located at one side of the expansion block 201e, which comprises a locking block 202a and a first spring 202b.
[0036] The locking member 202 is arranged to limit the position of the expansion block 201e, so as to avoid that the expansion block 201e is moved again under the action of external force after being moved to a proper position, thereby affecting the clamping effect on the grinding wheel 104.
[0037] The first spring 202b applies a continuous pushing force to the locking block 202a, so as to ensure that the locking block 202a can be clamped with the locking slot 201e-2, and when the two are clamped, the movement of the expansion block 201e along the sliding groove 201a-3 will be limited.
[0038] Embodiment 2
[0039] With reference to Figures 1-7 For the second embodiment of the utility model, the embodiment is based on the previous embodiment.
[0040] Specifically, one end of the locking block 202a is inclined, and the locking slot 201e-2 has a plurality of shapes corresponding to the locking block 202a.
[0041] Through the inclined arrangement, when the extrusion block 201b drives the expansion block 201e to move away from the connecting column 201c, the inclined surface of the locking slot 201e-2 will extrude the locking block 202a, so as to compress the first spring 202b, and then make the locking block 202a completely move into the rectangular groove 201a-4, at this time, the locking block 202a will not hinder the movement of the expansion block 201e, when the expansion block 201e moves towards the connecting column 201c, the right angle surface of the locking slot 201e-2 is combined with the right angle surface of the locking block 202a, and the first spring 202b will not be compressed, so as to hinder the movement of the expansion block 201e towards the connecting column 201c.
[0042] Due to the setting of the plurality of locking grooves 201e-2, when the rotating mechanism 103 drives the grinding wheel 104 to rotate synchronously, under the action of centrifugal force, the expansion block 201e will continue to move away from the connecting column 201c, so that the first spring 202b is compressed. As the expansion block 201e moves, when the locking block 202a moves to the coaxial position with the locking groove 201e-2 again, the two will be engaged again, thereby making the end face of the expansion block 201e closer to the inner wall of the center through hole of the grinding wheel 104. At the same time, due to the movement of the top of the expansion block 201e is also limited by the inner wall of the center through hole of the grinding wheel 104, the position of the expansion block 201e will be locked at this time, and the grinding wheel 104 is stably clamped.
[0043] Specifically, one end of the extrusion block 201b is inclined, and one side of the bottom of the expansion block 201e is inclined. The inclined surface of the extrusion block 201b is in contact with the inclined surface of the bottom of the expansion block 201e.
[0044] When the extrusion block 201b is pushed to move in the direction of the moving column 201d, the inclined surface of the extrusion block 201b will extrude the inclined surface of the bottom of the expansion block 201e, so that the expansion block 201e moves along the sliding groove 201a-3 to the outside of the fixed column 201a.
[0045] Specifically, the moving column 201d is fixed with a second spring 201f on one side, and the other end of the second spring 201f is fixed with the inner wall of the first moving groove 201a-1.
[0046] The second spring 201f continuously applies a pushing force to the moving column 201d. In the initial state, the distance between the expansion block 201e and the connecting column 201c is the closest, which can meet the clamping of the grinding wheel 104 with the smallest diameter of the center through hole.
[0047] Because the inclined surface of the extrusion block 201b is in contact with the inclined surface of the bottom of the expansion block 201e, and the inclined groove 201d-1 is in contact with the stress groove 201e-1, after the position of the expansion block 201e is locked, the positions of the extrusion block 201b, the connecting column 201c and the moving column 201d will be locked synchronously. After the locking block 202a is separated from the locking groove 201e-2, the second spring 201f will push the moving column 201d back to the initial state. At this time, the inclined groove 201d-1 will extrude the stress groove 201e-1, so that the expansion block 201e moves to the direction close to the connecting column 201c, and returns to the initial position.
[0048] Specifically, the end face of the extrusion block 201b protrudes from the end face of the fixed column 201a.
[0049] Specifically, one end of the expansion block 201e is fixed with an arc-shaped plate 201g, the side end face of the arc-shaped plate 201g away from the expansion block 201e has a certain deformation ability, and the surface is rough.
[0050] The arc-shaped plate 201g is in contact with the inner wall of the center through hole of the grinding wheel 104 at the side end away from the expansion block 201e, and the arc-shaped plate 201g can be continuously compressed under the action of centrifugal force due to the deformation capacity of one end of the arc-shaped plate 201g, so that the expansion block 201e is tightly attached to the inner wall of the center through hole of the grinding wheel 104, and the surface roughness is used to increase the friction force, which can prevent the workpiece from rotating or sliding in the clamp during polishing or processing, and ensure the processing precision.
[0051] Embodiment 3
[0052] Referring to Figures 1-7 For the third embodiment of the utility model, the embodiment is based on the first two embodiments.
[0053] Specifically, the number of expansion blocks 201e is three, and the moving column 201d has three inclined grooves 201d-1, and the inclined grooves 201d-1 correspond to the expansion blocks 201e one by one.
[0054] The three expansion blocks 201e and the corresponding arc-shaped plates 201g apply expansion force to the inner wall of the center through hole of the grinding wheel 104 from three directions, so as to ensure that the grinding wheel 104 can be stably fixed outside the fixed column 201a.
[0055] Specifically, the locking block 202a is fixed with a pull rod 202c, and one end of the pull rod 202c is fixed with a circular ring 202d.
[0056] Through the setting of the pull rod 202c, the pull rod 202c is used to unlock the clamping of the locking block 202a and the locking groove 201e-2, and the locking block 202a and the pull rod 202c are provided with three, corresponding to the three expansion blocks 201e, and the circular ring 202d is used to connect the three pull rods 202c, when the expansion block 201e needs to be restored, the circular ring 202d is pulled, and the three pull rods 202c are driven to move away from the locking block 202a, and then the first spring 202b is compressed, so that the locking block 202a is separated from the locking groove 201e-2, and at this time, under the action of the second spring 201f, the expansion block 201e will return to the initial position.
[0057] Specifically, one end of the fixed column 201a is fixed with a base 201h.
[0058] Specifically, the rotating mechanism 103 is fixed with a three-jaw chuck 105 on one side, and the workbench 101 is fixed with a polishing mechanism 106.
[0059] The three-jaw chuck 105 is used to clamp the base 201h. By rotating the wrench of the chuck, the three claws will shrink to the center at the same time, tightly clamping the base 201h. The rotating mechanism 103 rotates, driving the three-jaw chuck 105 to rotate, and then the base 201h rotates synchronously with the fixed column 201a, thereby driving the grinding wheel 104 to rotate. The outer edge of the grinding wheel 104 is polished by cooperating with the polishing mechanism 106. This is the prior art, and the working principle is clear to those skilled in the art, and will not be described in detail in this scheme. This is the prior art, and the working principle is clear to those skilled in the art, and will not be described in detail in this scheme.
[0060] In use, the grinding wheel 104 is sleeved outside the fixed column 201a, and one end face of the grinding wheel 104 is tightly attached to the base 201h. Then the extrusion block 201b is pushed to move in the direction of the moving column 201d. The inclined surface of the extrusion block 201b will extrude the inclined surface at the bottom of the expansion block 201e, so that the expansion block 201e moves along the sliding groove 201a-3 to the outside of the fixed column 201a, until the arc-shaped plate 201g away from the side end face of the expansion block 201e is tightly attached to the inner wall of the central through hole of the grinding wheel 104.
[0061] During this process, the inclined surface of the locking groove 201e-2 will extrude the locking block 202a, so that the first spring 202b is compressed, and then the locking block 202a is completely moved into the rectangular groove 201a-4. At this time, the locking block 202a will not hinder the movement of the expansion block 201e. When the expansion block 201e moves towards the connecting column 201c, the right angle surface of the locking groove 201e-2 and the right angle surface of the locking block 202a are attached, and the first spring 202b will not be compressed, thereby preventing the expansion block 201e from moving towards the connecting column 201c.
[0062] Then by rotating the wrench of the chuck, the three claws will shrink to the center at the same time, the three-jaw chuck 105 will tightly clamp the base 201h, and then start the power mechanism 102 to drive the rotating mechanism 103 to rotate, and then the base 201h rotates synchronously with the fixed column 201a, thereby driving the grinding wheel 104 to rotate. Under the action of centrifugal force, the arc-shaped plate 201g is continuously compressed, so that the expansion block 201e is attached more tightly to the inner wall of the central through hole of the grinding wheel 104. The expansion block 201e will continue to move away from the connecting column 201c, so that the first spring 202b is compressed. As the expansion block 201e moves, when the locking block 202a moves to the coaxial position with the locking groove 201e-2 again, the two will be engaged again, so that the end face of the expansion block 201e is closer to the inner wall of the central through hole of the grinding wheel 104. At the same time, the movement of the top of the expansion block 201e is also limited by the inner wall of the central through hole of the grinding wheel 104. At this time, the position of the expansion block 201e will be locked, and the grinding wheel 104 is stably clamped.
[0063] When the polishing is completed, the circular ring 202d is pulled to drive the three pull rods 202c to move away from the locking block 202a, so that the first spring 202b is compressed, the locking block 202a is separated from the locking groove 201e-2, the second spring 201f pushes the moving column 201d to return to the initial state, the inclined groove 201d-1 extrudes the stress groove 201e-1, so that the expansion block 201e moves to the direction close to the connecting column 201c and returns to the initial position, at this time, the arc-shaped plate 201g is separated from the inner wall of the center through hole of the grinding wheel 104, and the grinding wheel 104 can be taken off.
[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
