Description

Technical Field

[0001] The utility model belongs to the technical field of workpiece clamping, and in particular relates to a quick clamping device. Background Art

[0002] Hot runner is a heating component system used in injection molds to inject melted plastic particles into the mold cavity. Hot runner molds are a new structure that heats the runners and runners of traditional molds or three-plate molds, so that the runners and runners do not need to be removed during each forming process. Hot runner nozzles are required in the hot runner processing process, and clamping devices are required for the processing of hot runner nozzles.

[0003] The existing clamping device has a relatively simple structure and can only perform bilateral positioning clamping during clamping. When the workpiece is subjected to a force perpendicular to the clamping direction, the workpiece is prone to disengagement or even falling. The fixing stability is poor, and it is not convenient to adjust the rotation position after clamping. It is necessary to release the lock and adjust and then re-clamp, which is inconvenient to operate and has low efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a quick clamping device to solve the problems of the existing clamping device proposed in the above background technology, that is, the structure is relatively simple, and only bilateral positioning clamping can be performed during clamping. When the workpiece is subjected to a force perpendicular to the clamping direction, the workpiece is easily disengaged, deviated, or even dropped. The fixing stability is poor, and it is not convenient to adjust the rotation position after clamping. The locking adjustment needs to be released and re-clamped, which is inconvenient to operate and has low efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick clamping device, comprising a base, a plurality of strip holes are provided on the base and bolts are passed through the strip holes, a fixing seat and a fixing frame are welded on the upper surface of the base, a rotating drum is rotatably mounted on the fixing seat, a motor is fixedly mounted on the side of the rotating drum, an output shaft of the motor extends into the rotating drum and a disc is fixedly mounted thereon, four inclined slideways are provided on the disc and rollers are rotatably fitted in the inclined slideways, a fixing rod is rotatably mounted on the side of the roller, four straight slideways are provided on the side of the rotating drum, and the fixed rod The other end of the fixed rod passes through the straight slide and is detachably mounted with a clamping positioning plate, a gear ring is fixedly mounted on the outer surface of the rotating cylinder, and two lower fixed plates and two upper fixed plates are respectively fixedly mounted on the lower surface and upper surface of the inner wall of the mounting frame, a rotating shaft is rotatably mounted between the two lower fixed plates, a gear meshing with the gear ring is fixedly mounted on the outer surface of the rotating shaft, an operating turntable is fixedly mounted on one end of the rotating shaft, a plurality of locking holes are opened on the operating turntable, a locking rod used in conjunction with the locking hole is slidably mounted between the two upper fixed plates, and an operating plate is fixed to one end of the locking rod.

[0006] By adopting the above scheme, a rotating drum is arranged for use with a motor, and the motor drives the disc to rotate. The arrangement of the inclined slide and the straight slide can make the four fixed rods move synchronously inward and outward, thereby driving the four clamping positioning plates to move synchronously outward or inward, thereby realizing the positioning and clamping of the hot runner nozzle on all sides. The clamping stability is good, and it is not easy to loosen, disengage, deviate or misalign. By arranging gears and gear rings for use together, the rotating drum can be rotated and adjusted while keeping the hot runner nozzle fixed, thereby realizing the rotation adjustment of the hot runner nozzle, and the locking rod is used to lock the position, which is convenient for processing operations.

[0007] In the above solution, it should be noted that the motor is electrically connected to the external power supply.

[0008] As a preferred embodiment, a supporting ring is fixedly installed on the inner wall of the drum, and an annular track is fixedly installed on the outer surface of the disc, and the supporting ring rotates on the inner wall of the annular track.

[0009] By adopting the above solution, the supporting ring is used in conjunction with the annular track to support the rotation of the disc and avoid shaking of the disc when it rotates.

[0010] As a preferred embodiment, a guide rod is fixedly mounted on the inner wall of the straight slideway on the rotating drum, and the fixed rod is slidably mounted on the outer surface of the guide rod.

[0011] By adopting the above solution, the setting of the guide rod can limit the fixing rod, further ensuring the good movement of the clamping positioning plate.

[0012] As a preferred embodiment, a slot for inserting a fixing rod is provided on the side of the clamping positioning plate, a fixing pin is inserted on the clamping positioning plate, and a pin hole for inserting the fixing pin is provided on the surface of the fixing rod.

[0013] By adopting the above solution, the setting of the fixing pin can effectively lock the clamping positioning plate, making it easy to disassemble and assemble.

[0014] As a preferred implementation, an anti-slip tooth plate is fixedly mounted on the side of the clamping and positioning plate.

[0015] By adopting the above solution, the provision of the anti-skid tooth plate can improve the stability of the clamping action and avoid slipping.

[0016] As a preferred embodiment, a limiting ring is fixedly installed on the outer surface of the locking rod, a spring is fixedly installed between the limiting ring and one of the upper fixed plates, a connecting plate is fixedly installed between the two upper fixed plates, a positioning pin is inserted on the connecting plate, and a pin hole two for inserting the positioning pin is opened on the surface of the locking rod.

[0017] When the locking rod is disengaged from the locking hole, it elastically deforms, so the elasticity of the spring can be used to drive the locking rod to quickly reset and insert into the locking hole, thereby improving the convenience of the locking operation. When the locking rod is disengaged from the locking hole, the positioning pin can be inserted into the second pin hole, thereby realizing the locking of the locking rod movement and facilitating the rotation operation of the turntable.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The quick clamping device is used by setting a rotating drum in conjunction with a motor. The motor drives the disc to rotate. The inclined slide and the straight slide can make the four fixing rods move inward and outward synchronously, thereby driving the four clamping positioning plates to move outward or inward synchronously, thereby achieving positioning and clamping of the hot runner nozzle on all sides. The clamping stability is good and it is not easy to loosen, disengage, deviate or dislocate.

[0020] The quick clamping device is used in conjunction with a gear and a gear ring. The rotating drum can be rotationally adjusted while keeping the hot runner nozzle fixed, thereby realizing the rotation adjustment of the hot runner nozzle, and the position is locked by a locking rod, which is convenient for processing operations.

[0028] A supporting ring 19 is fixedly installed on the inner wall of the rotating drum 5, and an annular track 18 is fixedly installed on the outer surface of the disc 7. The supporting ring 19 rotates on the inner wall of the annular track 18. The supporting ring 19 cooperates with the annular track 18 to support the rotation of the disc 7 and avoid shaking when the disc 7 rotates.

[0029] A guide rod 20 is fixedly installed on the inner wall of the straight slideway on the rotating drum 5, and the fixing rod 9 is slidably installed on the outer surface of the guide rod 20. The setting of the guide rod 20 can limit the fixing rod 9, further ensuring the good movement of the clamping positioning plate 10.

[0030] A slot for inserting the fixing rod 9 is provided on the side of the clamping positioning plate 10, a fixing pin 21 is inserted on the clamping positioning plate 10, and a pin hole 1 for inserting the fixing pin 21 is provided on the surface of the fixing rod 9.
