Detailed Description
Specific embodiments of the present utility model are described in further detail below. It should be understood that the description herein of the embodiments of the utility model is not intended to limit the scope of the utility model.
Fig. 1 is a schematic structural view of a feeding mechanism of a screw thread rolling machine according to the present utility model. The screw thread rolling machine feeding mechanism comprises a base 10, a feeding assembly 20 arranged on one side of the base 10, a blocking assembly 30 arranged on one side of the feeding assembly 20, and a feeding runway 40 arranged on one side of the blocking assembly 30. It is conceivable that the screw thread rolling machine feeding mechanism further comprises some other functional modules, such as a driving module, a thread rolling machine module, etc., which are known technologies to those skilled in the art, and are not described in detail herein.
Please refer to fig. 2 to fig. 3 together. The base 10 comprises a body 11, a first chute 12 arranged at one side of the body 11, a second chute 13 arranged at one side of the first chute 12, and a baffle 14 arranged at one side of the body 11 far from the material feeding track 40.
The length direction of the first chute 12 is parallel to the length direction of the second chute 13. The first chute 12 mates with a portion of the feed assembly 20 and the second chute 13 mates with a portion of the stop assembly 30, as will be described in greater detail below.
The baffle 14 cooperates with the feeding assembly 20 and the blocking assembly 30 to achieve a feeding blocking function, and the specific cooperation thereof will be described below.
It should be noted that, a reciprocating device (not shown) that drives a swing arm to swing by cam rotation is provided at one side of the feeding mechanism of the screw thread rolling machine, so that the feeding assembly 20 can be intermittently pushed back and forth, and the reciprocating device should be the prior art and will not be described herein.
The feeding assembly 20 includes a first slider 21 disposed on the base 10, a first spring 22 disposed on one side of the first slider 21, and a feeding plate 23 fixedly disposed on the first slider 21.
The first slider 21 is slidably disposed in the first chute 12, and one side surface of the first slider 21 is provided with a stopper 24. The stopper 24 receives the intermittent pushing force of the reciprocating means described above, which is directed toward the first spring 22. One end of the first spring 22 is in contact with the first slider 21, and the other end is in contact with the shutter 14. One end of the feeding plate 23 is located at the discharge hole of the feeding runway 40, so when the stop block 24 receives intermittent thrust force towards the direction of the first spring 22, the first slider 21 slides in the first chute 12 towards the baffle 14 and compresses the first spring 22, so that the feeding plate 23 reaches the feeding start point, and then the stop assembly 30 is matched to enable a screw to reach the end of the feeding plate 23. When the thrust force received by the stop block 24 disappears, the first slider 21 will slide towards the feeding track 40 under the elastic potential energy of the first spring 22, so as to drive the feeding plate 23 to move and send the screw at the end of the feeding plate 23 into the thread rolling machine for thread rolling operation.
The top of the first slider 21 is provided with a push rod 25, and the push rod 25 can cooperate with the material blocking assembly 30 to perform material blocking operation, and the specific cooperation will be described below.
The material blocking assembly 30 comprises a rotating block 31 rotatably arranged on the base 10, a second sliding block 32 arranged on one side of the rotating block 31, a second spring 33 arranged on one side of the second sliding block 32, and a material blocking plate 34 fixedly arranged on the second sliding block 32.
The rotating block 31 is located between the first and second sliders 21, 32. A blocking post 35 is disposed on a side of the rotating block 31 adjacent to the first slider 21, and the blocking post 35 corresponds to the push rod 25, so that when the first spring 22 releases elastic potential energy, the push rod 25 can push the blocking post 35, and the rotating block 31 can rotate around its middle section.
An arc-shaped groove 36 is formed in one side, close to the second sliding block 32, of the rotating block 31, and a pin 37 is fixedly arranged at the top of the second sliding block 32. The pin 37 passes through the arc slot 36 and can be located in the arc slot 36 to move, so that when the rotating block 31 rotates, the arc slot 36 can change the position of the pin 37 along the length direction of the second sliding block 32, and further drive the second sliding block 32 to slide in the second sliding slot 13.
One end of the second spring 33 abuts against the second slider 32, and the other end abuts against the shutter 14. One end of the striker plate 34 is located at the discharge port of the incoming runway 40. When the first spring 22 releases elastic potential energy and pushes the first slider 21 to move towards the feeding track 40, the feeding plate 23 moves towards the feeding port of the thread rolling machine. Meanwhile, the rotating block 31 is driven by the push rod 25 to rotate, and the second slider 32 is driven by the rotating block 31 to move towards the baffle 14 and compress the second spring 33. One end of the striker plate 34 faces away from the discharge port of the incoming runway 40, thereby opening the discharge port and allowing a screw to complete the discharge operation. When the stopper 24 receives intermittent pushing force, the push rod 25 is away from the stopper 35. The second spring 33 releases elastic potential energy, so that the second slider 32 moves towards the feeding track 40, and further one end of the stop plate 34 stops the discharge hole of the feeding track 40, thereby completing the stopping operation.
Compared with the prior art, the feeding mechanism of the screw thread rolling machine provided by the utility model stores or releases elastic potential energy through the first spring to realize the reciprocating motion of the feeding plate 23 to finish feeding operation. Simultaneously, the rotating block 61 rotates through the push rod 55, and the reciprocating motion of the second sliding block 62 is realized under the cooperation of the second spring 63 to finish the material blocking operation. The mechanism can realize the cross operation of pushing and blocking, does not block materials during pushing, does not push materials during blocking, improves the discharging efficiency of screws, and avoids the problems of clamping materials and the like of the screws.
The above is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model, and any modifications, equivalent substitutions or improvements within the spirit of the present utility model are intended to be covered by the claims of the present utility model.
