Description

Technical Field

[0001] The invention relates to the technical field of chuck processing, and more specifically to a processing device for a power chuck capable of compensating clamping and automatically pushing materials. Background Art

[0002] A power chuck is a chuck driven by external power and is widely used in machine tool processing, automation equipment and other fields. Its main function is to clamp and fix the workpiece to ensure accuracy and stability during the processing. Unlike traditional manual chucks, power chucks use electric, pneumatic or hydraulic systems to provide clamping force, thereby improving the efficiency, stability and degree of automation of the clamping process.

[0003] The power chuck with compensatory clamping and automatic material ejection is mainly used when there is an error in the size of the clamped workpiece. It can automatically adjust within the designed range. Through the compensation effect, the clamped workpiece can be centered and the clamping force can be evenly applied to the jaws. It helps to improve production efficiency in mass production. After the workpiece is processed, the jaws can be released and the workpiece can be ejected pneumatically to achieve automatic material removal.

[0004] The floating plate is a key component in the power chuck that can compensate for clamping and automatically push materials. It is a key component that provides clamping adaptability, automatic centering, vibration absorption and error compensation. It greatly improves the overall processing quality and efficiency by ensuring the stability and accuracy of the workpiece during the processing. It is one of the key components in the power chuck that can compensate for clamping and automatically push materials.

[0005] However, in the process of high-precision machining, the thinner floating disc can reduce the mass of the chuck, thereby improving the dynamic response capability of the system. Especially in high-speed rotation or precision machining, the lighter floating disc can quickly adapt to speed changes, reduce vibration and instability, thereby improving machining accuracy. The thinner design helps to reduce the heat accumulation generated by the floating disc during high-speed rotation or high-temperature machining. As the thickness decreases, the thermal conductivity of the floating disc is enhanced, and it can dissipate heat faster, thereby reducing deformation caused by thermal expansion and maintaining higher machining accuracy. In addition, the design of the thin floating disc can improve the compensation effect, especially when the workpiece surface is uneven or there are slight errors. The thinner floating disc The position can be adjusted more flexibly to ensure that the workpiece is always in a good clamping state during the processing, thereby improving the processing quality. Therefore, in the current high-precision processing, thinner floating discs are usually used. However, in the process of processing thinner floating discs, due to the thinness of the floating disc, excessive clamping force will cause the workpiece to deform in the clamping area, affecting the processing accuracy, causing the thinner floating disc to easily bend or warp under the action of the clamping force, and the thin floating disc is prone to vibration during the turning process, especially when high cutting force or high-speed rotation is used. This vibration will cause poor surface quality and even increase tool wear, affecting processing efficiency and workpiece quality. Summary of the invention

[0006] The present invention provides a processing device for a power chuck that can compensate for clamping and automatically push materials. The problem to be solved is: during the production and processing of the existing thin floating disk, due to the thinness of the floating disk, excessive clamping force will cause deformation of the workpiece in the clamping area, affecting the processing accuracy, causing the thinner floating disk to easily bend or warp under the action of the clamping force, and the thin floating disk is prone to vibration during the turning process, especially when high cutting force or high-speed rotation is applied.

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Refer to the instruction manual Figures 1 to 4 A processing device for a power chuck capable of compensating clamping and automatically pushing materials comprises: a chuck base 1, on which a plurality of clamping claws 11 are arranged, and the plurality of clamping claws 11 clamp and fix a thin floating disk 2 by synchronous radial movement along the surface of the chuck base 1; A support member 3 is provided on the chuck base 1, and the support member 3 provides additional support when the thin floating disk 2 is clamped by contacting the bottom of the thin floating disk 2; An adsorption mechanism 4 is arranged in the support member 3, and the adsorption mechanism 4 includes a plurality of adsorption holes 41. The plurality of adsorption holes 41 are evenly arranged on the surface of the support member 3. An exhaust component is also arranged on the support member 3. When the thin floating disk 2 contacts the surface of the support member 3, the exhaust component exhausts the air in the support member 3 by exhausting air, so that the thin floating disk 2 is adsorbed and fixed on the surface of the support member 3.

[0035] It should be noted that the support member 3 is a support disk, and the surface diameter of the support member 3 is the same as that of the thin floating disk 2. There are three claws 11, and the thin floating disk 2 is clamped and fixed by the synchronous radial movement of the three claws 11. The control method of the claws 11 adopts the scheme commonly used in machine tool processing, which will not be described in detail here. The support of the thin floating disk 2 by the support member 3 can effectively increase the supporting force of the thin floating disk 2, reduce the possibility of deformation due to external force during the turning process, and provide higher rigidity. This support can effectively suppress the vibration and bending of the thin floating disk 2, improve the stability of the processing process, and ensure the processing accuracy. The exhaust component is an air pump. When the support member 3 is in contact with the thin floating disk 2, the air in the support member 3 is exhausted by the air pump, so that a negative pressure is formed in the support member 3, and the thin floating disk 2 can be adsorbed and fixed on the support member 3.

[0036] It should also be noted that an annular groove can be opened on the surface of the support member 3, and a sealing ring can be arranged in the annular groove, and the surface of the sealing ring and the surface of the support member 3 are on the same horizontal plane, so that when the support member 3 contacts the thin floating disk 2, it can be ensured that it is in a sealed state when in contact, which can ensure the sealing during vacuuming, so that the thin floating disk 2 can be stably adsorbed and fixed on the support member 3.

[0037] The specific implementation scenario is as follows: first, the thin floating disk 2 is placed on the support 3, and the three claws 11 are controlled to move radially synchronously so that the three claws 11 clamp and fix the thin floating disk 2, and then the air pump is used to evacuate the air in the support 3, so that negative pressure is formed in the support 3, and the thin floating disk 2 is adsorbed and fixed on the support 3. When the thin floating disk 2 is clamped, the thin floating disk 2 is supported by the support 3, which effectively increases the supporting force of the thin floating disk 2, reduces the possibility of deformation due to external force during the turning process, provides higher rigidity, and can effectively suppress the vibration and bending of the thin floating disk 2, improve the stability during the processing, and ensure the processing accuracy. During the turning process of the thin floating disk 2, the vibration of the workpiece will directly affect the stability of the contact between the turning tool and the workpiece, thereby affecting the processing accuracy and surface quality. While supporting through the support 3, the use of an adsorption and fixing method can more evenly distribute the force, reduce vibration, improve the turning quality, obtain a smoother surface, and further ensure the dimensional accuracy and surface quality during the turning process.

[0038] It should also be noted that using suction to adsorb the chuck base 1 can provide stronger adsorption force than simply relying on the support member 3 for support, especially for a thin floating disk 2 with a thin thickness. The thin floating disk 2 can be firmly fixed on the support member 3 by negative pressure suction, which can further reduce the movement or loosening of the thin floating disk 2 caused by vibration or external force, thereby ensuring its processing accuracy.

[0039] For further information, please refer to the attached manual. Figure 4 The adsorption mechanism 4 also includes an exhaust pipe 42, which is arranged on the support member 3, the air inlet end of the exhaust pipe 42 is connected to the interior of the support member 3, and the air outlet end of the exhaust pipe 42 is connected to the exhaust end of the exhaust component.

[0040] It should be noted that the vacuum assembly is an air pump, which drives the air pump to extract the air inside the support member 3 through the vacuum pipe 42, so that a negative pressure is formed inside the support member 3, and the thin floating plate 2 is adsorbed and fixed on the support member 3 through the adsorption holes 41 opened on the support member 3, so as to achieve the effect of adsorbing and fixing the thin floating plate 2.

[0041] In the above technical solution, when the thin floating disk 2 is first clamped by the clamping claws 11 and then fixed by adsorption, since the thin floating disk 2 is a workpiece to be processed, before the thin floating disk 2 is turned, it is impossible to ensure that the diameters of the thin floating disk 2 and the support member 3 are completely consistent, resulting in the size of the thin floating disk 2 not completely matching the diameter of the support member 3, and there will be a problem that the diameter of the thin floating disk 2 is slightly larger or slightly smaller than the diameter of the support member 3. When the diameter of the thin floating disk 2 is slightly smaller than the diameter of the support member 3, when the thin floating disk 2 is clamped by the clamping claws 11, due to the existence of the support member 3, the clamping claws 11 can only contact with the support member 3, causing the clamping claws 11 to be unable to contact with the thin floating disk 2. The moving plate 2 contacts and fixes the thin floating plate 2. At this time, the thin floating plate 2 can only be fixed by adsorption by the adsorption mechanism 4. Therefore, during the processing of the thin floating plate 2, when the thin floating plate 2 is driven to rotate at a high speed, the thin floating plate 2 is easily caused to slip under the action of centrifugal force, thereby affecting its processing quality. For this reason, the present invention proposes a telescopic mechanism 5. By setting the diameter of the support member 3 to be smaller than the diameter of the thin floating plate 2 and contacting the support member 3 through a slidable abutment plate 51, when the thin floating plate 2 is fixed, it can be ensured that the claws 11 can contact and fix the thin floating plate 2. At the same time, the slidable and telescopic abutment plate 51 can also ensure stable support for the bottom of the edge of the thin floating plate 2.

[0042] For details, please refer to the attached manual. Figure 5 and Figure 6 A telescopic mechanism 5 is provided on the claw 11, and the telescopic mechanism 5 includes a slidably arranged abutment plate 51. A slide groove 52 is opened on the claw 11, and the abutment plate 51 is slidably arranged in the slide groove 52. An elastic member 53 is also provided on the abutment plate 51, and one end of the elastic member 53 away from the abutment plate 51 is arranged on the inner wall of the slide groove 52.

[0043] It should be noted that the diameter of the support member 3 is smaller than the diameter of the thin floating disk 2, and the elastic member 53 is a spring. When fixing the thin floating disk 2, the thin floating disk 2 is first placed on the support member 3, and then the multiple claws 11 are driven to move radially to clamp the thin floating disk 2. During the radial movement of the claws 11, the abutment plate 51 will first contact the support member 3 and squeeze the spring until the claws 11 contact the thin floating disk 2, thereby clamping the thin floating disk 2.

[0044] In the above technical scheme, due to the installation of the thin floating plate 2 and the installation of the claws 11, it is usually necessary to provide a plurality of evenly distributed holes on the outer edge of the thin floating plate 2 for fixing the claws 11. Usually, the design of these holes allows the claws 11 to adjust their positions to adapt to the sizes or shapes of different workpieces. These holes are generally circular or elliptical and have a certain size and spacing. Therefore, when the adsorption and fixation are performed by the adsorption mechanism 4, there will be a problem that the holes opened on the thin floating plate 2 overlap with the adsorption holes 41. When the holes are aligned, the suction will cause air resistance and even form vortices due to the unstable airflow at the holes. These vortices not only affect the adsorption effect, but also cause the instability of the position of the thin floating plate 2, thereby affecting the positioning accuracy. For this reason, the present invention also proposes an adjustment mechanism 6 for sealing the adsorption holes 41 at this position when the holes opened on the thin floating plate 2 overlap with the adsorption holes 41.

[0045] For details, please refer to the attached manual. Figures 7 to 11 An adjustment mechanism 6 is provided in the adsorption hole 41, and the adjustment mechanism 6 includes a sliding shaft 61 slidably arranged in the adsorption hole 41. The adjustment mechanism 6 is used to block the adsorption hole 41 when the sliding shaft 61 is in the hole opened on the thin floating disk 2. A through hole 63 is opened on the sliding shaft 61. When the sliding shaft 61 completely slides into the adsorption hole 41, the through hole 63 is in a connected state with the interior of the support member 3. When the end of the sliding shaft 61 extends out of the adsorption hole 41, the through hole 63 is in an isolated state with the interior of the support member 3. The adjustment mechanism 6 also includes a side hole 64. The side hole 64 is opened on the top inner wall of the support member 3, and the side hole 64 is connected with the adsorption hole 41. An elastic member 62 is provided at the end of the sliding shaft 61.

[0046] It should be noted that the through hole 63 is a three-way setting, and its side holes 64 are set to two. When the sliding shaft 61 completely slides into the adsorption hole 41, the two side holes 64 are connected to the through hole 63. The elastic member 62 is a spring. When the thin floating plate 2 is processed, the thin floating plate 2 is first placed on the support member 3. At this time, the thin floating plate 2 will squeeze the sliding shaft 61, so that the sliding shaft 61 slides into the adsorption hole 41 and squeezes the spring. When the sliding shaft 61 slides into the adsorption hole 41, its through hole 63 can be connected with the side holes. 64 are connected so that when negative pressure suction is performed through the adsorption mechanism 4, the negative pressure suction can be completed through the connected through hole 63 and the side hole 64, so as to achieve the effect of adsorbing and fixing the thin floating plate 2. At the same time, for the position where the hole opened on the thin floating plate 2 coincides with the adsorption hole 41, the sliding shaft 61 can pass through the hole opened on the thin floating plate 2, and at this time, the through hole 63 and the side hole 64 at this position are not connected. Therefore, the position can be blocked to avoid the problem of eddy current.

[0047] In the above technical scheme, an adjustment mechanism 6 is provided to solve the problem of the overlap between the holes opened on the thin floating disk 2 and the adsorption holes 41. However, not only the problem of the overlap between the holes opened on the thin floating disk 2 and the adsorption holes 41 will arise, but also the problem of partial overlap between the holes opened on the thin floating disk 2 and the adsorption holes 41 will arise. At this time, due to the partial overlap, the thin floating disk 2 can still squeeze the sliding shaft 61 to slide into the adsorption hole 41. At this time, the air inlet end of the through hole 63 is not completely blocked, so that the unstable airflow at the hole will still cause air resistance and even form vortices. These vortices not only affect the adsorption effect, but also lead to the instability of the position of the thin floating disk 2, thereby affecting the positioning accuracy. For this reason, the present invention also proposes a sealing component 7 for solving the above-mentioned problems.

[0048] For details, please refer to the attached manual. Fig.12 A blocking component 7 is provided on the sliding shaft 61 , and the blocking component 7 is movably installed in the through hole 63 . A sealing member 71 is fixedly provided at the end of the blocking component 7 , and the sealing member 71 is in movably contact with the inner wall of the through hole 63 .

[0049] It should be noted that the sealing component 7 is a sealing cover, and the sealing member 71 is a rubber pad. The end of the sealing cover cooperates with the rubber pad to be tightly installed in the through hole 63. When the thin floating plate 2 is placed, it can be observed that the hole opened on the thin floating plate 2 overlaps with part of the adsorption hole 41. By installing the sealing component 7 on the sliding shaft 61 at this position, the sealing component 7 blocks the through hole 63. At this time, although the sliding shaft 61 is squeezed and slides into the adsorption hole 41, since the air inlet end of the through hole 63 is in a blocked state, it is possible to avoid the problem of unstable airflow at this position, which causes vortexes and affects the positioning accuracy.

[0050] In the above technical scheme, when the thin floating disk 2 is clamped and fixed by the claws 11, due to the thin thickness of the thin floating disk 2, the top height of the claws 11 is usually higher than the upper surface of the thin floating disk 2 when clamping and fixing. At this time, during turning, since the claws 11 are in contact with the edge of the thin floating disk 2, when the surface edge of the thin floating disk 2 is turned by the tool, the tool is easy to contact the claws 11, resulting in interference and causing safety accidents. For this reason, the present invention proposes a positioning mechanism 8, which is used to fix the inner ring of the thin floating disk 2 by a plurality of claws 81 that can support the surface of the support member 3 to move synchronously radially when turning the top edge of the thin floating disk 2, and release the fixation of the outer ring of the thin floating disk 2, so as to avoid the problem of the tool contacting the claws 11 and causing safety accidents.

[0051] For details, please refer to the attached manual. Fig.13 and Fig.14 A positioning mechanism 8 is provided on the support member 3, and the positioning mechanism 8 includes a plurality of clamping jaws 81 that can synchronously move radially along the surface of the support member 3. The positioning mechanism 8 uses the plurality of clamping jaws 81 that can synchronously move radially so that the plurality of clamping jaws 81 can be pressed against the inner ring of the thin floating disk 2 to fix the thin floating disk 2. The positioning mechanism 8 includes a driving shaft 82, and a disc 83 is installed at the output end of the driving shaft 82. The disc 83 is provided with a plurality of through openings 84. A plurality of circular shafts 85 are slidably provided in the support member 3, and the plurality of circular shafts 85 are slidably provided in the corresponding through openings 84, and the ends of the plurality of circular shafts 85 are fixedly connected to the corresponding clamping jaws 81. A plurality of limiting grooves 87 are provided in the support member 3, and limiting blocks 86 are slidably provided in the plurality of limiting grooves 87, and the plurality of limiting blocks 86 are fixedly connected to the corresponding circular shafts 85.

[0052] It should be noted that there are three clamps 81, and the driving shaft 82 can drive the disc 83 to rotate through a motor. By driving the disc 83 to rotate, the circular shaft 85 can move in the through opening 84, and the circular shaft 85 is limited by the limit block 86 and the limit groove 87, so that the three clamps 81 can move radially along the surface of the support member 3 synchronously, and contact the inner ring of the thin floating disc 2 to fix the thin floating disc 2. At this time, the clamping claw 11 is driven to release the fixation of the thin floating disc 2, so that the problem of contact between the tool and the clamping claw 11 can be avoided when turning the surface edge of the thin floating disc 2.

[0053] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
