Technical Field

[0001] This utility model relates to the field of pneumatic vise technology, specifically a pneumatic self-locking vise with replaceable clamping components. Background Technology

[0002] Pneumatic vises, also known as pneumatic bench vises, are commonly used clamping tools in industrial production and are widely used in the automotive, machinery, and electronics industries.

[0003] When using traditional pneumatic vises to clamp workpieces, problems such as unstable clamping, easy slippage, and vibration can occur due to unstable air pressure or external forces, which seriously affect product quality. By setting a self-locking mechanism, the pneumatic vise can still provide sufficient clamping force when the air pressure is unstable, thus improving processing safety.

[0004] Therefore, a pneumatic self-locking vise with replaceable clamping components is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a pneumatic self-locking vise with replaceable clamping components.

A first jaw is slidably connected to one side of the top of the housing, and a second jaw is slidably connected to the side of the top of the housing away from the first jaw. Mounting plates are symmetrically fixedly connected to the outside of both the first jaw and the second jaw. A slider is fixedly connected to the bottom of the first jaw through a connecting plate extending into the inside of the housing. A second inclined block is symmetrically slidably connected to the outside of the slider. Slide plates are slidably connected to both sides of the inside of the housing through limiting rods. A first inclined block that cooperates with the second inclined block is fixedly connected at equal intervals to the inner sides of the two slide plates.

[0007] Preferably, a cylinder is fixedly connected to the outer side of the housing via a mounting bracket, the output end of the cylinder extends into the interior of the housing and is fixedly connected to the connecting plate, and a first spring is provided inside the slider on one side of each of the two second inclined blocks.

[0008] Preferably, a bidirectional lead screw is rotatably connected to the inside of the housing away from the limiting rod, and the two slide plates are respectively connected to the outer sides of the bidirectional lead screw through a lead screw nut pair. A second spring is provided on both outer sides of the limiting rod and between the two slide plates and the inner wall of the housing.

[0009] Preferably, a first rack is fixedly connected to the outer side of the connecting plate, and a gear is rotatably connected to the inner side of the housing. The gear meshes with the first rack, and a second rack is fixedly connected to the bottom of the second jaw. The second rack meshes with the gear.

[0010] Preferably, a control switch is installed on the outer side of the housing, and the cylinder is electrically connected to the control switch.

[0011] Preferably, one end of the bidirectional lead screw extends to the outside of the housing and is fixedly connected to a knob, and the elastic force of the second spring is greater than that of the first spring.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0018] Please see Figure 1-5 As shown, a pneumatic self-locking vise with replaceable clamping components includes a housing 1. A first jaw 2 is slidably connected to one side of the top of the housing 1, and a second jaw 3 is slidably connected to the top of the housing 1 away from the first jaw 2. Mounting plates 4 are symmetrically fixedly connected to the exterior of both the first jaw 2 and the second jaw 3. A slider 6 is fixedly connected to the bottom of the first jaw 2 through a connecting plate 5 extending into the interior of the housing 1. A second inclined block 10 is symmetrically slidably connected to the exterior of the slider 6. Slide plates 8 are slidably connected to both sides of the interior of the housing 1 through limiting rods 7. The inner sides of the two slide plates 8 are equidistantly fixedly connected to... The first inclined block 9, which is matched with the second inclined block 10, has a cylinder 11 fixedly connected to the outer side of the housing 1 by a mounting bracket. The output end of the cylinder 11 extends into the interior of the housing 1 and is fixedly connected to the connecting plate 5. The slider 6 is provided with a first spring 12 on one side of each of the two second inclined blocks 10. A double-acting screw 13 is rotatably connected to the side of the housing 1 away from the limiting rod 7. The two slide plates 8 are respectively connected to the outer sides of the double-acting screw 13 by a screw nut pair. A second spring 14 is provided on both sides of the limiting rod 7 and between the two slide plates 8 and the inner wall of the housing 1.

[0019] During operation, when using this device, the workpiece is placed on the housing 1. The cylinder 11 is activated via the control switch 18, causing the first jaw 2 to move. This, in conjunction with the second jaw 3, clamps the workpiece. During the movement of the first jaw 2, the connecting plate 5 and the slider 6 move accordingly. The slider 6 causes the second inclined blocks 10 on both sides to slide repeatedly inward between the corresponding first inclined blocks 9, and can repeatedly pop out under the rebound force of the first spring 12. When the first jaw 2 stops moving, the second inclined blocks 10 on both sides of the slider 6 lock into place between the current first inclined blocks 9, achieving self-locking. When the air pressure in the cylinder 11 is unstable, the first inclined block 9 can limit the second inclined block 10 and the first jaw 2, preventing the clamping of the workpiece by the first jaw 2 and the second jaw 3 from loosening. It can provide sufficient clamping force for the pneumatic vise to ensure that the material does not loosen or fall, thereby improving the safety of machining and the precision of the product. By rotating the double-acting screw 13, the double-acting screw 13 drives the two slide plates 8 to move to both sides through the screw nut pair, while squeezing the two second springs 14, so that the first inclined blocks 9 on both sides can release the limit on the second inclined blocks 10, and the first jaw 2 and the second jaw 3 can be reset. After the reset is completed, the double-acting screw 13 is released, and the slide plates 8 can be driven to reset under the rebound force of the two second springs 14, which is convenient for subsequent use. Furthermore, the mounting plates 4 on the outside of the first jaw 2 and the second jaw 3 can be used to install and remove different models of clamping components, so that they can be adapted and replaced according to the different shapes of workpieces, thereby improving the flexibility of the device.

[0020] When the cylinder 11 experiences unstable air pressure during the clamping process of the workpiece through the first jaw 2 and the second jaw 3, the device can limit the second inclined block 10 by the first inclined block 9 on the two side slides 8. This self-locking force prevents the first jaw 2 and the second jaw 3 from loosening, and still provides sufficient clamping force for the pneumatic vise, ensuring that the material does not loosen or fall, thereby improving the safety of machining and the accuracy of the product. Different models of clamping components can be installed and disassembled through the mounting plate 4 on the outside of the first jaw 2 and the second jaw 3, so that they can be adapted and replaced according to the different shapes of workpieces, improving the flexibility of the device.

[0021] Among them, a first rack 15 is fixedly connected to the outer side of the connecting plate 5, a gear 16 is rotatably connected to the inner side of the housing 1, the gear 16 meshes with the first rack 15, and a second rack 17 is fixedly connected to the bottom of the second jaw 3, the second rack 17 meshes with the gear 16.

[0022] Through the above technical solution, the first jaw 2 can drive the first rack 15 to follow the movement during its movement. The first rack 15 then drives the gear 16 to rotate through the meshing relationship, so that the gear 16 drives the second rack 17 and the second jaw 3 to move inward. This achieves the purpose of self-centering of the pneumatic vise by the synchronous movement of the first jaw 2 and the second jaw 3, thereby improving the machining accuracy of the workpiece.

[0023] Among them, a control switch 18 is installed on the outer side of the housing 1, the cylinder 11 is electrically connected to the control switch 18, one end of the bidirectional lead screw 13 extends to the outside of the housing 1 and is fixedly connected to a knob, and the elastic force of the second spring 14 is greater than the elastic force of the first spring 12.

[0024] Through the above technical solution, the control switch 18 allows the operator to quickly control the cylinder 11. Example 2

[0025] Please see Figure 1 As shown in the first embodiment, as another implementation of this utility model, the outer sides of the housing 1 are fixedly connected with fixing plates 19, and the interior of the two fixing plates 19 are symmetrically provided with mounting holes 20.

[0026] During operation, the device can be easily fixed in the designated working position by the fixing plates 19 and mounting holes 20 provided on both sides of the housing 1, thereby further improving the processing stability of the device after clamping the workpiece.

[0027] Working principle: When using this device, the workpiece is placed on the housing 1. The cylinder 11 is started by the control switch 18, which drives the first jaw 2 to move. This, in conjunction with the second jaw 3, clamps the workpiece for processing. During the movement of the first jaw 2, the connecting plate 5 and the slider 6 move accordingly. The slider 6 drives the second inclined blocks 10 on both sides to slide repeatedly inward between the corresponding first inclined blocks 9, and can repeatedly pop out under the rebound force of the first spring 12. When the first jaw 2 stops moving, the second inclined blocks 10 on both sides of the slider 6 are locked onto the current first inclined block. Self-locking is achieved between 9. When the air pressure in cylinder 11 is unstable, the first inclined block 9 can limit the second inclined block 10 and the first jaw 2, preventing the first jaw 2 and the second jaw 3 from loosening their grip on the workpiece. This still provides sufficient clamping force for the pneumatic vise, ensuring that the material does not loosen or fall, thereby improving machining safety and product precision. By rotating the bidirectional lead screw 13, the two slide plates 8 move to both sides through the lead screw nut pair, simultaneously compressing the two second springs 14, causing the first inclined blocks 9 on both sides to release. By limiting the second inclined block 10, the first jaw 2 and the second jaw 3 can be reset. After the reset is completed, the bidirectional lead screw 13 is released, and the slide plate 8 can be reset under the rebound force of the two second springs 14, which is convenient for subsequent use. Furthermore, different models of clamping components can be installed and removed through the mounting plate 4 on the outside of the first jaw 2 and the second jaw 3, so that they can be adapted and replaced according to workpieces of different shapes, which improves the flexibility of the device. During the movement of the first jaw 2, the first rack 15 can be driven to move accordingly. The first rack 15 then... The meshing relationship drives the gear 16 to rotate, which in turn drives the second rack 17 and the second jaw 3 to move inward. This achieves the synchronous movement of the first jaw 2 and the second jaw 3, thus achieving the self-centering purpose of the pneumatic vise and improving the machining accuracy of the workpiece. The control switch 18 allows the operator to quickly control the cylinder 11. The fixing plates 19 and mounting holes 20 on both sides of the housing 1 make it easy to fix the device in the designated working position, thereby further improving the machining stability of the device after clamping the workpiece.
