Description

Technical Field

[0001] This utility model relates to the field of bolt production technology, specifically to a feeding device for a thread rolling machine used in bolt production. Background Technology

[0002] Bolts are common mechanical parts, typically consisting of a head and a shank, used to fasten two or more parts together, making them a single unit. Common shapes include hexagonal head, square head, round head, countersunk head, and semi-circular head. Hexagonal head bolts are the most widely used, as their hexagonal head makes tightening and loosening easy with tools such as wrenches. Square head bolts, with their square heads, also provide good torque transmission, but they occupy a larger area in the same space compared to hexagonal head bolts. Round head, countersunk head, and semi-circular head bolts are selected based on different installation requirements and appearance requirements. For example, countersunk head bolts can make the mounting surface relatively flat and are often used in situations where surface flatness is required.

[0003] In existing technologies, in large-scale bolt production in industries such as automobile manufacturing, machinery manufacturing, and building hardware, feeding devices can achieve automated feeding, quickly transporting large quantities of blanks to the processing position of the thread rolling machine. However, during use, when the feeding device needs to be moved within the workshop, it is usually inconvenient to move, which makes it difficult to arrange and adjust the position of the equipment. Moreover, the feeding device can usually only place bolts of a certain size and cannot be adjusted according to bolts of different widths, thus failing to meet the feeding needs of various bolt specifications and reducing the versatility of the device.

[0004] Therefore, a feeding device for a thread rolling machine for bolt production is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Example

[0025] The existing feeding devices are often inconvenient to move within the workshop, hindering equipment layout and adjustment. Furthermore, these devices typically only accommodate bolts of a certain size and cannot be adjusted for bolts of different widths, thus limiting their versatility. Therefore, this invention provides a preferred embodiment of a feeding device for a thread rolling machine used in bolt production. Figure 1-5 As shown: A feeding device for a thread rolling machine for bolt production includes a base 1, a support plate 2 fixedly installed on the top of the base 1, a movable adjustment component 3 provided inside the base 1, universal wheels 4 evenly and equidistantly arranged on both sides of the bottom of the movable adjustment component 3, a foot brake pedal 5 provided on the surface of the universal wheels 4, and a capacity adjustment component 6 provided on the top of the support plate 2.

[0026] The movable adjustment component 3 specifically includes: a base plate 311, which is set at the bottom of the base 1; a slide groove 312, which is opened on both sides of the inner wall of the base 1; a positive and negative threaded screw 314, which is rotatably connected to one side of the inner wall of the base 1; a bottom block 318, which is equidistantly fixed on both sides of the bottom of the base plate 311; and a hollow block 3111, which is fixedly installed on one side of the base 1.

[0027] A slide plate 313 is fixedly installed at equal intervals on the top of the base plate 311. The outer wall of the slide plate 313 is slidably connected to the inner wall of the slide groove 312. A slider 315 is threadedly connected at equal intervals on the outer wall of the positive and negative threaded rod 314. A recess 316 is fixedly installed at equal intervals on the bottom of the slider 315 and the top of the base plate 311. A push rod 317 is movably connected between the inner walls of the recess 316.

Example

[0030] Based on Embodiment 1, a preferred embodiment of the feeding device for a thread rolling machine for bolt production provided by this utility model is as follows: Figure 1-5 As shown: The capacity adjustment assembly 6 specifically includes: side plates 611, which are equidistantly fixedly installed on both sides of the top of the support plate 2; a rotating shaft 612, which is rotatably connected between the inner sides of the side plates 611; a conveyor belt 613, which is drively connected to the outer wall of the rotating shaft 612; a rotating rod 614, which is set on the top of the support plate 2; a pulley 615, which is fixedly sleeved on the outer wall of the rotating rod 614; a motor 616, which is fixedly installed on the inner wall surface of the support plate 2; a chute frame 618, which is fixedly installed on one side of the top of the support plate 2; a chute placement plate 6115, which is equidistantly and evenly fixedly installed on the outer wall of the conveyor belt 613; a hollow groove 6116, which is opened on the front and back of the chute placement plate 6115; a positive and negative threaded screw 6117, which is set on one side of the chute placement plate 6115; a connecting rod 61111, which is equidistantly slidably connected inside the hollow groove 6116; and a limiting plate 61112, which is fixedly installed on the inner side of the connecting rod 61111.

[0031] One end of the rotating rod 614 moves through the outer side of the side plate 611 and extends to the inner side of the side plate 611, and is fixedly connected to one end of the rotating shaft 612. The output end of the motor 616 is fixedly mounted with the pulley 617. The pulley 617 and the pulley 615 are connected by a belt.

[0032] A motor 619 is fixedly installed on one side of the slide rail frame 618. A rotating shaft is fixedly installed at the output end of the motor 619. The other end of the rotating shaft passes through one side of the slide rail frame 618 and extends into the interior of the slide rail frame 618. A lead screw 6111 is fixedly installed at the other end of the rotating shaft. A T-shaped slider 6112 is threadedly connected to the outer wall of the lead screw 6111. An electric push rod 6113 is fixedly installed at the bottom of the T-shaped slider 6112. A clamping cylinder 6114 is fixedly installed at the telescopic end of the electric push rod 6113. A scale is provided on one side of the top of the slide rail placement plate 6115.

[0033] The interior of the hollow groove 6116 is connected to the interior of the slide plate 6115. One end of the positive and negative threaded screw 6117 moves through one side of the slide plate 6115 and extends to the outside of the slide plate 6115. The outer wall of the positive and negative threaded screw 6117 is rotatably connected to the inner wall of the slide plate 6115. Rotating blocks 6118 are fixedly installed at both ends of the positive and negative threaded screw 6117. Sliding blocks 6119 are equidistantly threaded to the outer wall of the positive and negative threaded screw 6117. One side of the connecting rod 61111 extends into the interior of the slide plate 6115 and is fixedly connected to one side of the sliding block 6119.

[0034] In this example, the capacity adjustment component 6 can transport bolts of different sizes. The rotating block 6118 drives the positive and negative threaded screws 6117 to rotate, which in turn drives the slider 6119, connecting rod 61111, and limit plate 61112 to move inward, thus limiting the bolts of different sizes. The motor 616 starts and drives the pulley 615 to rotate, which in turn drives the pulley 617, rotating rod 614, and rotating shaft 612 to rotate via the belt. The bolts are then transported via the conveyor belt 613, thereby achieving the function of capacity adjustment.

[0035] Working Principle: First, when the feeding device needs to be moved, the universal wheels 4 facilitate movement, and the foot brake pedal 5 limits the universal wheels 4, allowing for convenient movement. When the height of the support plate 2 needs to be adjusted, rotating the knob 3113 drives the worm gear 3112 to rotate, which in turn drives the worm wheel 319 and the first positive and negative threaded screw 314 to rotate, further driving the first slider 315 inward. Through the concave block 316 and the push rod 317, the base plate 311 and the base block 318 are lowered, allowing for height adjustment of the feeding device. When conveying bolts of different sizes, the bolts are placed on the top sliding groove placement plate 6115. Rotating the rotating block 6118 drives the second positive and negative threaded screw 6117 to rotate, which in turn drives the second slider 6119, the connecting rod 61111, and the limiting plate 61112 to move inward. 61112 can limit bolts of different sizes. The movement distance of the limiting plate 61112 can be observed through a scale. When bolts need to be conveyed, motor 616 is started to drive pulley 615 to rotate. The belt drives pulley 617, rotating rod 614, and rotating shaft 612 to rotate. The bolts are conveyed by conveyor belt 613. Motor 619 is started to drive screw 6111 to rotate, which further drives T-shaped slider 6112 and electric push rod 6113 to move. The electric push rod 6113 drives clamping cylinder 6114 to descend. The clamping cylinder 6114 clamps the bolts on the slide plate 6115. Then the electric push rod 6113 is retracted, and the screw 6111 rotates to drive clamping cylinder 6114 to feed the bolts, thereby achieving the functions of movement adjustment and capacity adjustment.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
