Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a vise clamping end floating chuck. Background Art

[0002] When clamping a workpiece with a pneumatic vise, the two clamping surfaces must be parallel to secure the workpiece with surface contact. In practice, however, some parts have non-parallel clamping surfaces, resulting in only linear contact, not surface contact, making the clamping unstable. During machining, cutting forces can cause the workpiece to shift, resulting in substandard products. Therefore, a clamping device that ensures consistent stability and reliability during machining is required. To address this, we developed a floating chuck for the vise's clamping end. Summary of the Invention

[0003] (1) Technical problems solved

[0004] In view of the deficiencies in the prior art, the present invention provides a floating chuck at the clamping end of a vise, which solves the above-mentioned problems.

[0005] (2) Technical solution

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a floating chuck at the clamping end of the vise, including a base, at least two vise slides are provided on the base, the vise slides are connected to a driving source, and the driving source drives the vise slides to slide on the base to complete the clamping work, and a floating chuck that can rotate freely is provided on the side where the two vise slides are close to each other, the cross-section of the floating chuck is three-fifths circular, and the wall surfaces of the two floating chucks on the side close to each other are mirror-inclined. When the workpiece to be clamped is placed between the two vise slides, the driving source drives the vise slide to move, and then slides the two vise slides toward the side close to each other. When the floating chuck contacts the inclined surface of the workpiece surface, the two floating chucks will swing until the inclined surface of the floating chuck fits the workpiece surface. This solution can achieve face-to-face contact clamping when the clamped surfaces of the workpiece are not parallel and the non-parallel surfaces of each part are inconsistent, thereby maximizing the clamping force and ensuring firm clamping.

[0007] Preferably, a mounting groove is respectively formed on one side wall surface of the two vise sliders close to each other, the floating chuck is hinged to the inner wall of the mounting groove, and the inclined surface of the floating chuck extends to the outside of the mounting groove.

[0008] Preferably, rectangular grooves are provided on the inclined surfaces of the two floating chucks, and a protruding fixing device is provided inside the rectangular groove. When the side wall of the clamped object has a certain protrusion, during the clamping process, the protrusion will be stuck into the inside of the rectangular groove, and then the inclined surface of the floating chuck will fit into the clamping surface of the clamped object. At this time, the protruding fixing device will fix the protruding area of ​​the clamped object, complete the fixation of its protruding area, and further increase the stability of the clamping.

[0009] Preferably, the raised fixing device includes an extrusion block, a linkage block, a spring, a card block and a hinged rod. The inner wall of the rectangular groove is provided with a spring, and both ends of the spring are provided with connecting grooves connected to the rectangular groove. The connecting groove is an L-shaped groove. The extrusion block is arranged inside the rectangular groove, and a linkage block is provided inside the cavity. The cross section of the linkage block is T-shaped, and the linkage block extends through the cavity to the inside of the rectangular groove, and the extrusion block and the linkage block are fixedly connected together. A spring is fixedly installed on the inner wall of the cavity, and the spring and the linkage block are fixedly connected together. The inside of the connecting groove is hinged with a hinged rod, and the hinged rod corresponds to the connecting groove and is connected to the rectangular groove. A clamping block is hinged on one side, and the clamping block extends to the inside of the rectangular groove. When the raised area of ​​the clamped workpiece is inserted into the inside of the rectangular groove, the length of the clamping block gradually extends into the inside of the rectangular groove. At this time, when the raised area squeezes the extrusion block, the extrusion block will move toward the side close to the spring. At this time, the spring contracts, and the two ends of the linkage block located inside the spring will squeeze the two ends of the connecting groove located in the cavity, causing the two connecting grooves to move away from each other. At this time, the other end of the connecting groove will move toward the side close to the rectangular groove, causing the two clamping blocks to move toward the inside of the rectangular groove until the clamping block is in contact with the wall surface of the raised area of ​​the workpiece, clamping it and fixing it.

[0010] Preferably, the two connecting grooves extend from one end of the card block to the interior of the cavity, and a magnet is provided at one end of the connecting groove close to the linkage block. Magnets are provided at the positions corresponding to the two connecting grooves of the linkage block. The magnets on the connecting groove and the magnets on the linkage block have different poles. When the spring is in a normal state without contraction, the connecting groove and the linkage block are in contact. At this time, the two card blocks will be located on the inner wall of the connecting groove and remain flush with the inner wall of the rectangular groove.

[0011] Preferably, the clamping surfaces of the two floating chucks are provided with knurling, grooves, dot matrix or rubber to increase the friction during clamping.

[0012] (3) Beneficial effects

[0013] Compared with the prior art, the present invention provides a floating chuck for the vise clamping end, which has the following beneficial effects:

[0014] 1. The floating chuck at the clamping end of the vise will automatically adapt to the non-parallel state of the clamped surface when the vise slider moves in the clamping direction, thereby clinging to the clamped surface and making the two clamping surfaces fit completely, reliably clamping the workpiece and ensuring that the part does not loosen or deviate when subjected to processing force.

[0015] 2. The floating chuck at the clamping end of the vise, during the clamping process, the protrusion will be stuck into the inside of the rectangular groove, and then the inclined surface of the floating chuck will fit into the clamping surface of the clamped object. At this time, the protruding fixing device will fix the protruding area of ​​the clamped object, completing the fixation of its protruding area, further increasing the stability of the clamping.

[0016] 3. The floating chuck at the clamping end of the vise, when the floating chuck contacts the inclined surface of the workpiece, the two floating chucks will swing until the inclined surface of the floating chuck fits the workpiece surface. This solution can achieve face-to-face clamping when the clamped surfaces of the workpiece are not parallel and the non-parallel surfaces of each part are inconsistent, thereby maximizing the clamping force and ensuring firm clamping.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3The movable jaws 4 are provided with a plurality of movable jaws 2 for supporting the workpiece 1 and the movable jaws 4 are provided with a plurality of movable jaws 2 for supporting the workpiece 1. The movable jaws 4 are provided with a plurality of movable jaws 2 for supporting the workpiece 1.

[0023] Furthermore, a mounting groove 3 is respectively opened on the side wall of the two vise sliders 2 close to each other, the floating chuck 4 is hinged to the inner wall of the mounting groove 3, and the inclined surface of the floating chuck 4 extends to the outside of the mounting groove 3.

[0024] Furthermore, rectangular grooves 5 are provided on the inclined surfaces of the two floating chucks 4, and a protruding fixing device is provided inside the rectangular grooves 5. When the side wall of the clamped object has a certain protrusion, during the clamping process, the protrusion will be stuck into the inside of the rectangular groove 5, and then the inclined surface of the floating chuck 4 will fit into the clamping surface of the clamped object. At this time, the protruding fixing device will fix the protruding area of ​​the clamped object, complete the fixation of its protruding area, and further increase the stability of the clamping.

[0025] Furthermore, the raised fixing device includes an extrusion block 6, a linkage block 7, a spring 9, a card block 11 and a hinged rod 12. The inner wall of the rectangular groove 5 is provided with a spring 9. Both ends of the spring 9 are provided with connecting grooves 10 connected to the rectangular groove 5. The connecting groove 10 is an L-shaped groove. The extrusion block 6 is arranged inside the rectangular groove 5. The linkage block 7 is provided inside the cavity 8. The cross section of the linkage block 7 is T-shaped. The linkage block 7 extends through the cavity 8 to the inside of the rectangular groove 5, and the extrusion block 6 and the linkage block 7 are fixedly connected together. A spring 9 is fixedly installed on the inner wall of the cavity 8. The spring 9 is fixedly connected to the linkage block 7. The interior of the connecting groove 10 is hinged with a hinged rod 12. The hinged rod 12 corresponds to the connecting groove 10 connected to the rectangular groove 5. A clamping block 11 is hinged on one side, and the clamping block 11 extends to the inside of the rectangular groove 5. When the raised area of ​​the clamped workpiece is inserted into the inside of the rectangular groove 5, the length of the protrusion gradually extends into the inside of the rectangular groove 5. At this time, when the raised area is squeezed into the extrusion block 6, the extrusion block 6 will move toward the side close to the spring 9. At this time, the spring 9 contracts, and the two ends of the linkage block 7 located inside the spring 9 will squeeze the connecting groove 10 located at the two ends of the cavity 8, causing the two connecting grooves 10 to move away from each other. At this time, the other end of the connecting groove 10 will move toward the side close to the rectangular groove 5, causing the two clamping blocks 11 to move toward the inside of the rectangular groove 5 until the clamping block 11 is in contact with the wall surface of the raised area of ​​the workpiece, clamping it and fixing it.

[0026] Furthermore, the ends of the two connecting grooves 10 away from the card block 11 extend to the interior of the cavity 8, and a magnet is provided at the end of the connecting groove 10 close to the linkage block 7. The linkage block 7 is provided with magnets at the positions corresponding to the two connecting grooves 10. The magnets on the connecting groove 10 and the magnets on the linkage block 7 have different poles. When the spring 9 is in a normal state without contraction, the connecting groove 10 is fitted with the linkage block 7. At this time, the two card blocks 11 will be located on the inner wall of the connecting groove 10 and remain flush with the inner wall of the rectangular groove 5.

[0027] The inner wall width of the rectangular groove 5 needs to be set according to the actual needs of the workpiece protrusion to be clamped, so that when the floating chucks 4 on both sides are not parallel to the workpiece surface, the protruding area on the workpiece can still be clamped into the inside of the rectangular groove 5, and when the clamping block 11 clamps the protrusion on the workpiece, only one clamping block 11 in the protrusion fixing devices on both sides needs to be against the protruding area of ​​the workpiece, so as to complete the auxiliary fixation of the protruding area. Figure 3 shown.

[0028] Furthermore, the clamping surfaces of the two floating chucks 4 are provided with knurling, grooves, dot matrix or rubber to increase the friction during clamping.

[0029] During use, the driving source drives the vise slider 2 to move, and then slides the two vise sliders 2 toward each other. When the floating chuck 4 contacts the inclined surface of the workpiece surface, the two floating chucks 4 will swing until the inclined surface of the floating chuck 4 fits the workpiece surface. This solution can achieve face-to-face clamping when the clamped surfaces of the workpiece are not parallel and the non-parallel surfaces of each part are inconsistent, thereby maximizing the clamping force and ensuring firm clamping.

[0030] When the raised area of ​​the clamped workpiece is inserted into the rectangular groove 5, the length of the raised area gradually extends into the rectangular groove 5. At this time, when the raised area is squeezed into the extrusion block 6, the extrusion block 6 will move toward the side close to the spring 9. At this time, the spring 9 contracts, and the two ends of the linkage block 7 inside the spring 9 will squeeze the connecting groove 10 at the two ends of the cavity 8, causing the two connecting grooves 10 to move away from each other. At this time, the other end of the connecting groove 10 will move toward the side close to the rectangular groove 5, causing the two clamping blocks 11 to move toward the inside of the rectangular groove 5 until the clamping block 11 is in contact with the wall surface of the raised area of ​​the workpiece, clamping it and fixing it.
