Description

Technical Field

[0001] The utility model relates to the field of parts processing, in particular to a reversible clamping tool for processing mechanical parts. Background Art

[0002] When processing mechanical parts, in order to facilitate the operation of various parts of the parts, clamping fixtures can be used to clamp the parts, and then the processing direction of the mechanical parts can be changed by flipping the fixture, thereby improving the processing efficiency and quality of the mechanical parts.

[0003] At present, when mechanical parts are clamped by clamping fixtures, in order not to affect the operation, usually only the two opposite end faces of the parts are clamped. Therefore, during the flipping process, if the flipping speed is fast, the parts may overcome the friction with the clamping fixture under the action of inertia and rotate again, causing the parts to break away from the clamping fixture, which is inconvenient for processing the parts. Therefore, in order to solve the above problem, a flip clamping fixture for processing mechanical parts is proposed. Utility Model Content

[0007] Preferably, the end of the left connecting rod of the fixing sleeve away from the fixing sleeve is fixedly connected to the output end of the motor, and the motor can be driven to make the connecting rod drive the fixing sleeve to rotate inside the fixing plate, so that the fixing sleeve drives the component to flip, and the sliding rod is slidably connected to the inside of the fixing sleeve. When the threaded rod is rotated to drive the pressure plate to clamp the component, the sliding rod can keep the pressure plate moving stably.

[0008] Preferably, an inner groove penetrating the pressure plate is provided on both the left and right sides of the pressure plate, the cylinder is fixedly installed inside the inner groove, and the slider and the connecting block extend to the outside of the inner groove.

[0011] Preferably, the cross-section of the clamping block is L-shaped, and the four clamping blocks can limit the four corners of one end of the component, so that the component remains stable when flipped.

[0012] The utility model is beneficial in that:

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.

[0024] The following is combined with Figure 1-6 To further explain this application,

[0025] The embodiment of the present application discloses a reversible clamping tool for machining mechanical parts. Figure 1The left and right sides of the pressing plate 25 are fixedly mounted with sliding rods 26, and the end of the connecting rod 21 on the left side of the fixing sleeve 22 is fixedly connected to the output end of the motor 23. The motor 23 can be driven to drive the connecting rod 21 to drive the fixing sleeve 22 to rotate inside the fixing plate 1, so that the fixing sleeve 22 drives the parts to flip, and the sliding rod 26 is slidably connected to the inside of the fixing sleeve 22. When the threaded rod 24 is rotated to drive the pressing plate 25 to clamp the parts, the sliding rod 26 can keep the pressing plate 25 moving stably, and a limiting component 3 is provided on the surface of the pressing plate 25.

[0026] Reference Figure 2-Figure 4 When the locking cam 315 is unlocked, the locking cam 315 is unlocked, and the winch 300 is unlocked, so the winch 300 is unlocked.

[0027] Reference Figure 4-Figure 6The connecting block 313 is provided with a cavity 33 inside. The cavity 33 passes through one end of the connecting block 313 close to the edge of the pressure plate 25. The sliding column 321 passes through the left and right sides of the connecting block 313. The end of the pressure spring 1 323 away from the limiting plate 322 is fixedly installed on the surface of the connecting block 313. The upper and lower ends of the sliding column 321 are fixedly installed with the sliding block 1 34. The inner wall of the cavity 33 is fixedly installed with a column 351. The surface of the column 351 away from the middle side of the connecting block 313 is slidably connected to the sliding block 2 352. The surface of the column 351 is fixedly installed with the pressure spring 2 353. The proximal ends of sliding block 1 34 and sliding block 2 352 are both provided with inclined edges adapted for sliding. The end of pressure spring 2 353 away from column 351 is fixedly mounted on the surface of sliding block 2 352. The proximal ends of sliding block 1 34 and sliding block 2 352 fit together. At this time, sliding block 2 352 is in a state of stretching pressure spring 2 353. The end of sliding block 2 352 away from the middle of connecting block 313 is fixedly mounted with a clamping block 354. The cross-sectional shape of the clamping block 354 is L-shaped. The four clamping blocks 354 can limit the four corners of one end of the component, so that the component remains stable when flipped.

[0028] Working principle: After the operator places the component inside the fixing sleeve 22, the two threaded rods 24 are rotated to push the two pressing plates 25 closer to each other. At this time, the two pressing plates 25 clamp the front and back sides of the component;

[0029] Then the operator drives the two cylinders 311 on the left and right sides, so that the two cylinders 311 respectively drive the two sliders 312 to move closer to each other. At this time, the sliders 312 drive the connecting blocks 313 to move accordingly. Then, the two connecting blocks 313 drive the sliding posts 321 and the limiting plates 322 to move accordingly until the left and right limiting plates 322 are respectively attached to the left and right sides of the component. Then, the limiting plates 322 compress the pressure spring 1 323 until the pressure spring 1 323 can no longer be compressed. At this time, the left and right limiting plates 322 limit the left and right sides of the component.

[0030] When the cam 352 is in the state of being in equilibrium, the pressure spring 353 is in the state of being stretched, and the sliding block 354 is attached to the surface of the sliding block 352. At this time, the sliding block 352 is restricted on the surface of the post 351 by the friction between the sliding block 352 and the post 351. When the limiting plate 322 is attached to the surface of the component, the limiting plate 322 pushes the sliding post 321 in the direction away from the component. At this time, the sliding post 321 drives the sliding block 34 to move along and disengage from the sliding block 352. At this time, the sliding block 352 will move toward the middle direction of the sliding post 321 under the action of the rebound force of the pressure spring 353

[0031] Afterwards, the operator drives the motor 23 to rotate the fixing sleeve 22 through the connecting rod 21 , and the parts clamped inside the fixing sleeve 22 are turned over, so that the operator can process various parts of the parts.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
