Description

Technical Field

[0001] The utility model relates to the field of fastener processing equipment, in particular to a thread rolling plate of a fastener thread rolling machine. Background Art

[0002] Screws are a type of fastener. There are many varieties and specifications of screws, with different performances and uses, and they are highly standardized, serialized, and universal. Screws are the most widely used basic mechanical parts and are in great demand. For example, in the automobile air intake system, a double-headed adjusting screw is required. In the prior art, screws are usually threaded with a thread rolling plate, that is, two thread rolling plates are used, and thread rolling surfaces are provided on the opposite sides of the two thread rolling plates. The bolt blank is placed between the two thread rolling plates, and the two thread rolling plates move relative to each other to thread the product.

[0003] The existing thread rolling machines use two thread rolling plates. A motor drives one of the thread rolling plates to move and cooperate with the other fixed thread rolling plate to realize the thread rolling process of the thread rolling plates. This method requires driving one of the thread rolling plates to perform reciprocating motion along a complete path of the thread rolling plate length, which undoubtedly increases the time consumed by the reciprocating motion of the thread rolling plate and reduces the thread rolling work efficiency.

[0009] Further, the forward and backward movement path of the tooth plate is equal to one-half of the length of the lower tooth plate or the upper tooth plate.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] The present utility model movably installs the lower tooth plate and the upper tooth plate in the guide rail, and connects them to a driving device by means of the tooth plates provided on their sides, so that the driving device synchronously drives the lower tooth plate and the upper tooth plate to move in opposite directions, enabling the upper tooth plate not to need to move completely to the front end of the lower tooth plate during tooth threading, realizing that the lower tooth plate and the upper tooth plate move by themselves for half, reducing the movement range of the lower tooth plate, thereby reducing the time of the reciprocating movement of tooth threading, and further improving the working efficiency of tooth threading.

[0018] The following elaborates on the preferred embodiments of the present utility model in conjunction with the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0019] The present utility model provides a tooth threading plate for a fastener tooth threading machine, asFigures 1-3 As shown, it includes a lower rubbing tooth plate 1, an upper rubbing tooth plate 2 and a guide rail 3. The lower rubbing tooth plate 1 and the upper rubbing tooth plate 2 are in a corresponding relationship up and down, and are slidably installed in the two guide rails 3 respectively. A sliding groove 32 is opened on one side of the two guide rails 3, and a leakage groove 31 is opened on the bottom guide rail 3, and the leakage groove 31 is located at the front end of the lower rubbing tooth plate 1. The leakage groove 31 is used for discharging the screw after the rubbing is completed. The lower rubbing tooth plate 1 and the upper rubbing tooth plate 2 are fixedly connected with a tooth plate 4 at the leakage groove 32, and the two tooth plates 4 are transmitted between The tooth plate 4 arranged on the side thereof is connected with a driving device, so that the driving device synchronously drives the lower tooth plate 1 and the upper tooth plate 2 to move in opposite directions, so that the upper tooth plate 2 does not need to move completely to the front end of the lower tooth plate 1 during tooth rubbing, and the lower tooth plate 1 and the upper tooth plate 2 can move half of themselves, thereby reducing the movement range of the lower tooth plate 1, thereby reducing the time of the reciprocating motion of the tooth rubbing, and thus improving the working efficiency of the tooth rubbing.

[0020] Specifically, Figure 4 As shown, limited edges 11 are welded on the middle parts of both sides of the lower tooth-gripping plate 1, and the limited edges 11 are in sliding contact with the top of a guide rail 3 at the bottom. A groove 12 is provided on the bottom surface of the lower tooth-gripping plate 1, and a number of rollers 13 arranged equidistantly are rotatably installed inside the groove 12, and the bottom of the roller 13 is in rolling contact with the top edge of a guide rail 3 at the bottom. The lower tooth-gripping plate 1 is rollingly connected to a guide rail 3 at the bottom through a number of rollers 13 rotatably installed in the groove 12, thereby reducing friction therebetween and reducing wear. The groove 12 is used to abut against the top edge of the guide rail 3 to avoid uneven force on the lower tooth-gripping plate 1 during tooth-gripping, causing one end of the lower tooth-gripping plate 1 to tilt up, thereby ensuring the stability of the sliding installation of the lower tooth-gripping plate 1.

[0021] Specifically, Figure 5 As shown, support edges 21 are welded to the middle parts of both sides of the upper tooth rolling plate 2, and a plurality of equally spaced ball bearings 22 are embedded in the bottom of the support edges 21. The ball bearings 22 are rotated and embedded in the support edges 21, and the bottom of the ball bearings 22 are in rolling contact with the bottom edge of a guide rail 3 at the top. The upper tooth rolling plate 2 is rollingly connected to a guide rail 3 at the top through the plurality of ball bearings 22 embedded in the bottom of the support edges 21, thereby reducing the friction therebetween and reducing wear. The support edges 21 abut against the bottom edges of the guide rails 3 to avoid uneven force on the upper tooth rolling plate 2 during tooth rolling, thereby ensuring the stability of the sliding installation of the upper tooth rolling plate 2.

[0022] As one of the embodiments, Figures 1-3As shown in the figure, the driving device includes a motor 5, a speed reducer 6, and a gear 7. The output shaft of the motor 5 is drivingly connected to the input end of the speed reducer 6, and the output end of the speed reducer 6 is fixedly connected to the gear 7. The gear 7 is placed between two toothed plates 4 and meshes with the two toothed plates 4. The motor 5 is a reciprocating driving motor, and its working principle is as follows: First, the motor 5 drives the speed reducer 6 to perform reciprocating operation, and then the speed reducer 6 drives the gear 7 to rotate. Under the action of the speed reducer 6, the rotation speed of the gear 7 is adjusted, so that the gear 7 drives the upper and lower toothed plates 4 to perform synchronous forward and backward movement, realizing the movement and threading of the lower threading plate 1 and the upper threading plate 2.

[0023] Specifically, the forward and backward movement path of the toothed plate 4 is equal to half of the length of the lower threading plate 1 or the upper threading plate 2, so that the movement paths of the lower threading plate 1 and the upper threading plate 2 are exactly equal to the length of a complete threading plate, realizing that the lower threading plate 1 and the upper threading plate 2 each move half, reducing the movement range of the lower threading plate 1, thereby reducing the time of the reciprocating threading movement.

[0024] It should be noted that: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected. "Upper", "lower", "left", "right", etc. are only used to represent the relative position relationship.
