Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be described more clearly and more completely with reference to the drawings in the following embodiments, and it is understood that the described embodiments are only a part of the present invention, rather than all of the present invention, and based on the embodiments, other embodiments obtained by those skilled in the art without inventive exercise are within the protection scope of the present invention.

As shown in fig. 1-3, a lockable clamping device suitable for multiple models of automobile engine cylinder covers comprises an adjusting assembly 1 connected with a mechanical arm, two clamping assemblies 2 used for clamping the engine cylinder covers are slidably arranged in the adjusting assembly 1, and support sheets 22 of the clamping assemblies 2 penetrate through holes of the engine cylinder covers and form supports in the engine cylinder covers to lock the engine cylinder covers.

The clamping assembly 2 comprises an adjusting rod 21, a pulling piece 23 and a moving ring 24, wherein the moving ring 24 controls one end to be hinged to a supporting piece 22 at the lower end of the adjusting rod 21 through driving the pulling piece 23 to move so as to retract and release. When the moving ring 24 moves downwards, the supporting sheet 22 is pushed to be unfolded through the pulling sheet 23, and the engine cylinder cover is locked, otherwise, when the moving ring 24 moves upwards, the supporting sheet 22 is pulled to be folded and contracted through the pulling sheet 23, and the supporting sheet 22 is separated from the hole of the engine cylinder cover.

The support pieces 22 are arranged in a plurality and are annularly distributed on the outer side of the adjusting rod 21. The arrangement of the plurality of supporting pieces 22 shares the weight of a single supporting piece 22 to the engine cylinder head, and ensures the stable use of the supporting pieces 22.

A first fixed ring 25 and a second fixed ring 26 are fixedly connected to the outer wall of the adjusting rod 21 from top to bottom, respectively, the moving ring 24 moves between the first fixed ring 25 and the second fixed ring 26, and a spring 27 for supporting the moving ring 24 downward is disposed between the moving ring 24 and the first fixed ring 25. The setting of first retainer plate 25 and second retainer plate 26 is used for injecing the upper and lower slip range that removes circle 24, avoid removing the breaking away from of circle 24, second retainer plate 26 is injecing the below that removes circle 24, it has a fixed point to realize removing circle 24 and move down, thereby it has the injecing to the angle of opening of backing sheet 22, it is too big to guarantee backing sheet 22 to open the angle, be unfavorable for the use, spring 27 is used for promoting moving the moving downwards of circle 24, thereby prop backing sheet 22 and open, all be provided with a small segment branch 271 on the first retainer plate 25 of both ends about spring 27 and the removal circle 24 simultaneously, be used for injecing spring 27, avoid the removal of spring 27 and drop.

A lock lever 28 is slidably provided on a surface of the first retainer ring 25, a lower end of the lock lever 28 is fixedly connected to the movable ring 24, a slide groove 281 is provided on an upper end of the lock lever 28, and a lower end of the hydraulic cylinder 29 is slidably connected to an inside of the slide groove 281. The hydraulic rods at the lower ends of the locking rod 28 and the hydraulic cylinder 29 slide freely, when the movable ring 24 is moved upwards due to the shrinkage of the support piece 22 entering the hole of the engine cylinder head, the locking rod 28 moves upwards, but the hydraulic rods slide in the sliding grooves 281 of the locking rod 28 and have no influence on the sliding grooves, otherwise when the support piece 22 needs to be folded and retracted and is separated from the hole of the engine cylinder head, the hydraulic cylinder 29 drives the hydraulic rods to shrink, the hydraulic rods firstly slide upwards in the sliding grooves 281 of the locking rod 28 and then slide to the uppermost end, the locking rod 28 is driven to move upwards, the moving ring 24 is pulled by the upward movement of the locking rod 28, and the movable ring 24 pulls the support piece 22 to fold through the pull piece 23 to achieve shrinkage.

The adjusting assembly 1 comprises a cross beam 11, and the cross beam 11 is connected with a mechanical arm through a mounting piece 12 and used for transferring an engine cylinder cover which is clamped completely. The arm realizes pressing from both sides tightly the engine cylinder cap through clamping subassembly 2, shifts it afterwards.

The motor 13 is fixedly connected to the side face of the cross beam 11, the motor 13 adjusts the positions of the two sliding blocks 15 in the cross beam 11 through the screw 14, and the sliding blocks 15 are fixedly connected with the clamping assembly 2 through the connecting rods 16. The screw directions in the two sliding blocks 15 are opposite, the motor 13 drives the two sliding blocks 15 to move in opposite directions through the screw 14, namely the screw 14 rotates forwards, so that the two sides of the two sliding blocks 15 move to realize separation, and on the contrary, the screw 14 rotates backwards, so that the middle of the two sliding blocks 15 moves to realize folding.

When in use: at first the arm drives clamping subassembly 2 through installed part 12 and carries out the regulation of position for clamping subassembly 2 is located engine cylinder lid directly over, starter motor 13 afterwards, motor 13 drives screw rod 14 and rotates, thereby carry out the regulation removal of position with two inside sliders 15 of crossbeam 11, make two clamping subassemblies 2 that 15 below drove correspond the last two different holes of engine cylinder lid respectively, move down of utilizing the arm afterwards, slowly push away clamping subassembly 2 in the hole of engine cylinder lid.

Further: when the reloading assembly 2 goes deep into a hole of an engine cylinder cover, the free end of the supporting sheet 22 hinged to the adjusting rod 21 contracts slowly in the hole, the free end of the supporting sheet 22 contracts slowly to extrude the pulling sheet 23, so that the pulling sheet 23 pushes the moving ring 24 to move upwards on the adjusting rod 21, meanwhile, the moving ring 24 moves upwards to extrude the spring 27 so that the spring 27 contracts, meanwhile, the moving ring 24 moves upwards to drive the locking rod 28 to move upwards, so that the lower end of the hydraulic cylinder 29 slides passively in the sliding groove 281 formed in the upper end of the locking rod 28, when the clamping assembly 2 goes deep into the engine cylinder cover completely, the extension of the spring 27 pushes the moving ring 24 to move downwards, the moving ring 24 moves downwards to push the pulling sheet 23 to extend outwards, so that the free end of each supporting sheet 22 is opened to lock the engine cylinder cover, and the clamping assembly is driven by a mechanical arm to.

Further: when the clamping assembly 2 is separated from the engine cylinder cover, the clamping assembly 2 is pushed downwards for a certain distance again, the clamping assembly 2 is deeper, then the hydraulic cylinder 29 is started, the hydraulic rod is contracted and firstly slides to the uppermost end in the sliding groove 281 at the upper end of the locking rod 28, then the hydraulic cylinder continuously moves upwards, the locking rod 28 pulls the moving ring 24 to move upwards, the moving ring 24 moves upwards to drive the pulling piece 23 to move upwards, the free end of the supporting sheet 22 is folded and retracted due to the upward movement of the pulling piece 23, and then the clamping assembly 2 is separated from the hole of the engine cylinder cover through the contraction of the mechanical arm.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
