Description

Technical Field

[0001] The utility model relates to the technical field of processing clamping devices, in particular to a precision machinery manufacturing processing clamping device. Background Art

[0002] When machining and manufacturing are performed in the prior art, it is often necessary to clamp the workpiece to facilitate processing, such as drilling, grinding, etc.

[0003] However, in the prior art, such clamping devices, such as the Chinese patent application number 202323375948.9 for a precision machinery manufacturing clamping device, clamp the workpiece by driving the clamping device through a bidirectional screw when in use. However, when facing anisotropic parts (parts with concave and convex surfaces), it is difficult to make the clamping device close to the workpiece surface using the simple clamping principle mentioned above. This will reduce the clamping effect of the workpiece and make it easy to shake. This cannot meet the needs when facing precision machinery manufacturing. Therefore, an improved precision machinery manufacturing and processing clamping device is needed to address this problem. Utility Model Content

[0004] The purpose of the present utility model is to provide a precision mechanical manufacturing and processing clamping device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a precision machinery manufacturing and processing clamping device, comprising a base plate, a clamping mechanism for clamping fixed parts is provided at the upper end of the base plate, the clamping mechanism comprises a fixed rod, a fixed plate, a movable plate, a clamping bin, a gear, a telescopic rod, a rack, and a fixed block, a fixed rod is fixedly provided on one side of the upper end of the floor, a fixed plate is fixedly provided on the side of the upper end of the base plate away from the fixed rod, a movable plate is movably sleeved on the outer surface of the fixed rod, a clamping bin is fixedly provided on the outer surfaces of the movable plate and the fixed plate, a gear is movably provided on the middle part of the inner side of the clamping bin through a rotating shaft, telescopic rods are fixedly provided on both sides of the inside of the clamping bin, a rack is fixedly provided on the movable end of the telescopic rod, and a fixed block is fixedly provided on one end of the rack.

[0006] Preferably, the rack and the gear are meshed with each other. The device meshes with two racks on both sides of the gear, so that a linkage structure can be formed. When the fixed block moves in the direction of the workpiece to be fixed, the surface of the workpiece is flat, and the fixed block fits the surface of the workpiece at the same time. At this time, the two racks can form a self-locking and will not move, and the two fixed blocks are normally squeezed on the surface of the workpiece to fix the workpiece.

[0007] Preferably, if the part has irregular concave and convex parts, when the fixed block on one side contacts the convex part, as the movable plate moves, the fixed block and the rack will no longer move, thereby causing the telescopic rod to contract, causing the rack to contract into the clamping bin, and at this time it will drive the gear to rotate, and push the rack on the other side forward through the gear, causing the telescopic rod on the other side to extend until the fixed block on the other side contacts the concave point of the workpiece, at which time the two fixed blocks and the two racks will form a self-locking function; thereby, the part can be fixed tightly against the concave and convex parts, so the fixing effect is better, which can facilitate precision machinery manufacturing.

[0008] Preferably, a mounting plate is fixedly provided at one end of the fixed rod, a rotating ring is movably provided at the middle inner side of the mounting plate through a bearing, and a screw is fixedly provided at the middle of the movable plate, so that the screw and the movable plate can be driven to move by rotating the rotating ring.

[0010] Preferably, a spring is provided inside the telescopic rod, which can automatically push the telescopic rod to reset so that the telescopic rod and the rack remain in the same position. Figure 2 Status shown.

[0011] Preferably, a handle is fixedly provided on the outer surface of the rotating ring, and the rotating ring can be easily rotated by the handle.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model can conveniently clamp regular parts, and can also conveniently clamp special-shaped parts, and can be fixed closely to the concave and convex parts of the parts during clamping, so that the fixing effect is better, thereby facilitating precision machinery manufacturing.

[0014] 2. The utility model is easy to operate. It only needs to rotate the rotating ring to automatically fix it according to the concave and convex of the workpiece without other adjustment steps, so it can be easily promoted and used. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0020] See also Figure 1-3 The utility model provides a technical solution: a precision machinery manufacturing and processing clamping device, comprising a base plate 1, a clamping mechanism for clamping fixed parts is provided at the upper end of the base plate 1, and the clamping mechanism includes a fixed rod 2, a fixed plate 3, a movable plate 4, a clamping bin 5, a gear 6, a telescopic rod 7, a rack 8, and a fixed block 9. A fixed rod 2 is fixedly provided on one side of the upper end of the floor, and a fixed plate 3 is fixedly provided on the side of the upper end of the base plate 1 away from the fixed rod 2. A movable plate 4 is movably sleeved on the outer surface of the fixed rod 2, and a clamping bin 5 is fixedly provided on the outer surfaces of the movable plate 4 and the fixed plate 3. A gear 6 is movably provided on the inner middle part of the clamping bin 5 through a rotating shaft. Telescopic rods 7 are fixedly provided on both sides of the inside of the clamping bin 5, and a rack 8 is fixed on the movable end of the telescopic rod 7, and a fixed block 9 is fixed on one end of the rack 8.

[0021] The rack 8 and the gear 6 are meshed with each other. The device meshes with two racks 8 on both sides of the gear 6, so that a linkage structure can be formed. When the fixing block 9 moves in the direction of the workpiece to be fixed, the surface of the workpiece is flat, and the fixing block 9 fits the surface of the workpiece at the same time. At this time, the two racks 8 can form a self-locking and will not move. The two fixing blocks 9 are normally squeezed on the surface of the workpiece to fix the workpiece;

[0022] If the part is irregularly concave and convex, when the fixed block 9 on one side contacts the convex part of the part, as the movable plate 4 moves, the fixed block 9 and the rack 8 will no longer move, thereby causing the telescopic rod 7 to contract, causing the rack 8 to retract into the clamping chamber 5, and at this time, the gear 6 will be driven to rotate, and the rack 8 on the other side will be pushed forward by the gear 6, so that the telescopic rod 7 on the other side is extended until the fixed block 9 on the other side contacts the concave point of the workpiece. At this time, the two fixed blocks 9 and the two racks 8 will form a self-locking function; thereby, they can be fixed tightly against the concave and convex parts of the part, so that the fixing effect is better, which makes it convenient to carry out precision machinery manufacturing;

[0023] A mounting plate 10 is fixedly provided at one end of the fixed rod 2, a rotating ring 11 is movably provided at the middle of the inner side of the mounting plate 10 through a bearing, and a screw 12 is fixedly provided at the middle of the movable plate 4. By rotating the rotating ring 11, the screw 12 and the movable plate 4 can be driven to move;

[0024] The interior of the rotating ring 11 is screwed together with the outer surface of the screw rod 12 through a threaded connection;

[0025] The telescopic rod 7 is provided with a spring inside, which can automatically push the telescopic rod 7 to reset, so that the telescopic rod 7 and the rack 8 are kept in the same position. Figure 2 Status shown;

[0026] A handle 13 is fixedly provided on the outer surface of the rotating ring 11, and the rotating ring 11 can be easily rotated by the handle 13;

[0027] Working principle: When using this device, the device rotates the rotating ring 11 through the handle 13, and then drives the screw 12 and the clamping bin 5 on one side to translate, so that the fixed block 9 can move toward the workpiece. When the fixed block 9 moves toward the direction of the workpiece to be fixed, the surface of the workpiece is flat, and the fixed block 9 fits the surface of the workpiece at the same time. At this time, the two racks 8 can form a self-locking and will not move. The two fixed blocks 9 are normally pressed against the surface of the workpiece to fix the workpiece;

[0028] If the part is irregularly concave and convex, when the fixed block 9 on one side contacts the convex part of the part, as the movable plate 4 moves, the fixed block 9 and the rack 8 will no longer move, thereby causing the telescopic rod 7 to contract, causing the rack 8 to retract into the clamping chamber 5, and at this time, the gear 6 will be driven to rotate, and the rack 8 on the other side will be pushed forward by the gear 6, so that the telescopic rod 7 on the other side is extended until the fixed block 9 on the other side contacts the concave point of the workpiece. At this time, the two fixed blocks 9 and the two racks 8 will form a self-locking function; thereby, they can be fixed tightly against the concave and convex parts of the part, so that the fixing effect is better, which makes it convenient to carry out precision machinery manufacturing;

[0029] Moreover, the device is easy to operate and only needs to rotate the rotating ring 11 to automatically fix the workpiece according to the concave and convex shape without other adjustment steps, so it can be easily promoted and used.
