Description

Technical Field

[0001] The utility model relates to the technical field of machine tool equipment, in particular to a clamp for a super finishing machine. Background Art

[0002] In the field of ultra-precision grinding, oilstone is a key grinding tool. Its stability and clamping method directly affect the processing accuracy and efficiency. Traditional oilstone fixtures often use simple clamping methods, such as a single-piece clamping oilstone rack. This type of fixture has many inconveniences when installing and debugging the oilstone, and there are other problems that affect the processing.

[0003] First, existing oilstone fixtures often require other tools, such as screwdrivers, when installing and replacing oilstones. This design not only increases the complexity of the operation, but may also cause the oilstone position to shift during installation, thereby affecting the processing accuracy.

[0004] Secondly, the clamping mechanism design of the existing fixture is not reasonable, resulting in unstable clamping effect. During the processing, the oilstone may loosen or even fall off due to insufficient clamping force, which will not only damage the oilstone, but also cause damage to the superfinishing machine. At the same time, excessive clamping force may also cause uneven wear on the oilstone surface, affecting the processing quality and even causing the oilstone to break.

[0005] Furthermore, existing fixtures are difficult to meet the clamping requirements of oilstones of different sizes and shapes. In actual operation, operators may need to frequently replace fixtures or adjust the clamping position of the fixture, which not only increases the operation time, but may also affect the continuity and stability of the processing.

[0006] Based on this, the applicant proposed a fixture for a superfinishing machine to solve the above technical problems. Utility Model Content

[0041] The following will clearly and completely describe the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments described in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1:

[0042] like Figures 1 to 14 As shown, the utility model is a clamp for a super-finishing machine, comprising a clamp base 1 connected to the swing mechanism of the super-finishing machine, the clamp base 1 is provided with a mounting seat 11, and the mounting seat 11 is provided with an iris adjustment mechanism, the iris adjustment mechanism includes an adjusting disk 3, and the opening size of the iris adjustment mechanism is adjusted by the adjusting disk 3, and a locking disk 4 is movably provided on the mounting seat 11, and a ratchet ring 31 is provided on the adjusting disk 3, and at least one pawl 44 is correspondingly provided on the locking disk 4. Rotating the adjusting disk 3 causes the iris adjustment mechanism to clamp the oilstone, and at the same time, the pawl 44 cooperates with the ratchet ring 31 to limit the reversal of the adjusting disk 3, thereby fixing the oilstone, and pulling the lock disk 4 in a direction away from the adjusting disk 3 causes the pawl 44 to disengage from the ratchet ring 31, thereby releasing the limit of the adjusting disk 3, and a through hole is coaxially provided on the mounting seat 11, the adjusting disk 3 and the lock disk 4 for installing the oilstone.

[0043] At least one mounting groove 42 is provided on the lock disk 4, a fixed shaft 43 is provided in the mounting groove 42, the fixed shaft 43 is rotatably connected to the pawl 44, and a spring 45 is provided between the pawl 44 and the mounting groove 42. In the initial state, the pawl 44 extends out of the mounting groove 42.

[0044] When in use, put the oilstone into the through hole to the appropriate position, rotate the adjusting disk 3, and drive the iris adjustment mechanism to close and clamp the oilstone. Since the upper side of the adjusting disk 3 and the locking disk 4 cooperate through the ratchet ring 31 and the pawl 44, real-time locking is achieved to prevent the adjusting disk 3 from reversing and causing the oilstone to loosen. Rotate the adjusting disk 3 until it cannot rotate, and the iris adjustment mechanism can clamp the oilstone.

[0045] In order to ensure the locking force, a plurality of ratchets 44 can be provided on the lock disk 4 and evenly distributed around the circumference.

[0046] The clamping mechanism of the utility model is more reasonably designed, ensuring the stability of the clamping effect. Through the precise mechanism design, the clamp can provide moderate clamping force, which will neither cause the oilstone to loosen or fall off due to insufficient clamping force, nor cause uneven wear or breakage of the oilstone surface due to excessive clamping force. This stable clamping effect not only protects the oilstone and the super-finishing machine, but also significantly improves the processing quality.

[0047] A plurality of limiting columns 112 are provided on the mounting seat 11, and a limiting hole 41 is correspondingly provided on the locking disk 4. The limiting columns 112 are connected to the limiting holes 41. The locking disk 4 is arranged on the upper side of the adjusting disk 3, and the adjusting disk 3 is provided with a plurality of arc holes 32. The limiting columns 112 pass through the arc holes 32 and are connected to the locking disk 4. A limiting convex ring 113 is provided at the end of the limiting column 112, and two limiting grooves 411 are provided in the limiting hole 41 along the axial direction. The limiting convex ring 113 is adapted to the limiting groove 411, and a connecting groove 412 is provided between the limiting grooves 411. The maximum diameter of the connecting groove 412 is smaller than the maximum diameter of the limiting groove 411.

[0048] In the locked state, the limiting protrusion 113 cooperates with the limiting groove 411 located above. At this time, the pawl 44 cooperates with the ratchet ring 31. When the oilstone needs to be replaced, the lock disk 4 is pulled upward. At this time, the limiting protrusion 113 disengages from the limiting groove 311 above, passes through the connecting groove 412 and enters the limiting groove 411 below. At this time, the pawl 44 disengages from the ratchet ring 31, releasing the reverse limit lock on the lock disk 4, and the oilstone can be removed by reversing the lock disk 4.

[0049] In order to allow the limiting convex ring 113 to pass through the connecting groove 412 smoothly, the diameter of the connecting groove 412 can be set to be slightly smaller than the maximum diameter of the limiting groove 411 to avoid the difference being too large, which makes it difficult for the limiting convex ring 113 to pass through. However, the difference cannot be too small to avoid the lock disk from easily detaching during the operation of the equipment, causing the oilstone to fall off. The specific parameters can be set by those skilled in the art according to actual needs and actual working conditions. At the same time, in this embodiment, the limiting convex ring 113 can also be set to a rubber with a certain elasticity as needed. It is fixedly connected to the limiting column 112. The rubber is squeezed and deformed and can also pass through the connecting groove 412 smoothly.

[0050] The utility model abandons the traditional single-clip clamping design and adopts a more advanced iris adjustment mechanism. At the same time, clamping is achieved through the cooperation of the ratchet ring and the pawl between the adjusting disk and the locking disk, and unlocking is achieved through the cooperation of the locking disk and the limit column. This design greatly simplifies the installation and replacement process of the oilstone, and no longer requires reliance on other tools such as screwdrivers, thereby reducing the complexity of the operation and the problem of oilstone position offset caused by improper use of tools, thereby improving the processing accuracy.

[0051] A redundant groove 413 is further provided in the limiting hole 41 , and the redundant groove 413 is connected to the limiting groove 411 located at the bottom.

[0052] The design of the redundant groove 413 ensures that when the limiting protrusion 113 enters the limiting groove 411 below, if the pawl 44 and the ratchet ring 31 are still not disengaged, the user can continue to pull up the lock disk 4 to make the limiting protrusion 113 enter the redundant groove 413, further moving the pawl 44 away from the ratchet ring 31, ensuring that the two are disengaged and releasing the lock of the adjustment disk 3. The size design of the redundant groove 413 can refer to the connecting groove 412, and can also be designed separately by those skilled in the art as needed.

[0053] The iris adjustment mechanism also includes an adjustment block 2 slidably arranged on the mounting seat 11, the adjustment block 2 is evenly arranged along the circumference around the axis of the mounting seat 11, the adjustment block 2 is slidably connected to the adjustment disk 3, the adjustment block 2 includes a clamping block 21, a slider A23 is provided on the lower side of the clamping block 21, a plurality of sliding grooves A111 are evenly provided on the mounting seat 11 along the circumference around its axis, the slider A23 is cooperated with the corresponding sliding grooves A111, a slider B22 is provided on the upper side of the clamping block 21, a plurality of sliding grooves B34 are evenly provided on the lower side of the adjustment disk 3 around its axis along the circumference, the slider B22 is cooperated with the corresponding sliding grooves B34, the tip of the clamping block 21 abuts against the side of the adjacent clamping block 21, the side of the clamping block 21 is also provided with anti-slip grooves, and a plurality of anti-slip protrusions 33 are provided on the outer side of the adjustment disk 3.

[0054] The iris adjustment mechanism can easily adapt to oilstones of different sizes and shapes without the need for frequent fixture changes or adjustments to the clamping position. This feature not only reduces operation time, but also improves the continuity and stability of processing, bringing higher efficiency to super-finishing processing.

[0055] The clamp base 1 also includes a clamp handle 12 fixedly connected to the outer side of the mounting base 11. The clamp handle 12 is connected to a connecting handle 14 through a connecting block 13. The axis of the clamp handle 12 does not coincide with the axis of the connecting handle 14, ensuring that the clamp can swing.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims, not the foregoing description, and it is intended that all variations within the meaning and scope of equivalents of the claims be encompassed within the present invention. Any reference numerals in the claims should not be construed as limiting the claim to which they relate.

[0057] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
