Description

TECHNICAL FIELD

[0001] The utility model belongs to bolt processing technical field, concretely relates to a push material subassembly of wire drawing machine. BACKGROUND

[0002] Bolt is mechanical part, cylindrical fastener with nut with thread. By head and screw rod (cylinder with external thread) two parts constitute a kind of fastener, need to cooperate with nut, for fastening connection two parts with through hole. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so bolt connection is detachable connection. Thread grinding machine is the thread processing machine tool that uses shaped grinding wheel as abrasive tool to process precision thread. In production, thread grinding machine is usually used to process thread form of bolt or tap.

[0003] The Chinese patent document with the application number CN202420410079.4 discloses a capacitor aluminum shell bolt wire drawing machine, which comprises a bottom plate, symmetrically distributed inclined support frames are further arranged above the bottom plate, inclined plates are fixedly connected above the inclined support frames, electric cylinder mounting plates are fixedly connected on the two sides of the inclined plates, a gear frame is further fixedly connected above the bottom plate, a motor mounting plate is fixedly arranged on one side of the gear frame, and a stepping motor is fixedly connected above the motor mounting plate. The utility model drives the second bevel gear and the runner to rotate synchronously through the stepping motor, drives the two sliding mounting plates to reciprocate through the connecting arm, makes the second wire drawing plate on one side of the two sliding mounting plates reciprocate synchronously, so that the two bolts to be processed between the first wire drawing plate and the second wire drawing plate are synchronously wire-drawn.

[0004] However, the existing wire drawing machine, although it realizes the function of effectively producing and processing bolts, still has some deficiencies. The push block for entering the two wire drawing plates is driven by an electric cylinder as an independent power source, which needs to be completely consistent with the eccentric shaft beat of the driving wire drawing moving plate. The driving sources of the two are independent of each other, which needs the participation of an additional control system. This mechanical form is relatively complex in structure, the reliability needs to be improved, and the economy is weak. UTILITY MODEL CONTENTS

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0006] A push material subassembly of wire drawing machine, comprising:

[0007] Rotating wheel, side is inclined surface;

[0008] Swing rod, one end side is attached to the inclined surface, the other end is rotatably connected with a horizontal moving rod, and the other end of the horizontal moving rod extends into the rack;

[0009] A spring is arranged outside the frame and sleeved on the outer periphery of the transverse rod.

[0010] A supporting block is rotationally connected to the middle part of the swing rod.

[0011] A notch is formed in the end of the swing rod, and at least one set of bearings is arranged in the notch.

DETAILED DESCRIPTION

[0029] In order for those skilled in the art to better understand the utility model, the technical scheme of the utility model is further described below in combination with the drawings and examples.

[0030] Wherein, the drawings are only used for example description, and the representation is only a schematic diagram, not a real object diagram, and cannot be understood as a limitation on the patent; in order to better illustrate the examples of the utility model, some components of the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some known structures and their descriptions in the drawings can be omitted.

[0031] As Figure 1 - Figure 6 The utility model discloses a bolt thread rolling tool, it includes thread rolling movable plate assembly 1, thread rolling fixed plate assembly 2, power assembly 3 and pushing assembly 4;

[0032] The thread rolling fixed plate assembly 2 is arranged in parallel with the thread rolling movable plate assembly 1, and the spacing width between the two is not less than the diameter of the bolt to be rolled.

[0033] The power assembly 3 is used to drive the thread rolling movable plate assembly 1 to reciprocate linearly relative to the thread rolling fixed plate assembly 2.

[0034] The pushing assembly 4 is arranged on the side of the thread rolling fixed plate assembly 2.

[0035] A feeding channel 5 is arranged on one side of the pushing assembly 4, and the feeding channel 5 sequentially feeds the bolts 7 to the pushing assembly 4, and under the action of the pushing assembly 4, the bolts 7 enter the spacing between the thread rolling movable plate assembly 1 and the thread rolling fixed plate assembly 2.

[0036] The thread rolling fixed plate assembly 2 used in the thread rolling tool can adjust the driving fixed plate seat 20 and the fixed plate body 21 to move transversely through the adjusting mechanism 22, so as to adjust the gap distance between the thread rolling fixed plate assembly 2 and the thread rolling movable plate assembly 1, and thus match the size of the bolt 7 to be rolled, and have higher adaptability.

[0037] Specifically, as shown in the figure, Figure 6 the thread rolling fixed plate assembly 2 comprises a fixed plate seat 20, a fixed plate body 21 connected to the side of the fixed plate seat 20, and an adjusting mechanism 22. The adjusting mechanism 22 drives the fixed plate seat 20 to move in the spacing width direction, so as to make the fixed plate body 21 and the thread rolling movable plate assembly 1 approach or move away from each other.

[0038] The thread rolling fixed plate assembly 2 further comprises a sliding rail 23 connected to the fixed plate seat 20.

[0039] The sliding rail 23 is arranged, so that the thread rolling fixed plate assembly 2 can move more smoothly in the transverse direction, and has better smoothness.

[0040] Specifically, the bottom of the fixed plate seat 20 is provided with a dovetail groove 200 matched with the sliding rail 23. Compared with other groove structures, the dovetail groove 200 has better tightness and is not easy to loosen. In addition, an oil injection hole connected to the dovetail groove 200 can be arranged on the fixed plate seat 20, so as to facilitate the addition of lubricating liquid.

[0041] The adjusting mechanism 22 in the embodiment can be driven by a screw assembly, and the structure thereof comprises a mounting seat 220, a handle 222, and a rotating rod 221 penetrating through the mounting seat 220 and connected to the fixed plate seat 20. Of course, the adjusting mechanism 22 can also have other structural forms, such as a telescopic air cylinder.

[0042] The fixed plate body 21 in the thread rolling fixed plate assembly 2 is connected to the fixed plate seat 20 in a mortise and tenon structure, or directly connected by a bolt 7, which is not limited in detail.

[0043] In addition, a discharge hopper 6 is arranged on the side of the thread rolling fixed plate assembly 2, which can guide the thread rolled bolt 7, so as to facilitate the centralized collection of the bolt 7, and then enter the next processing procedure.

[0044] The thread rolling moving plate assembly 1, the power assembly 3 and the material pushing assembly 4 are prior art, the power assembly 3 has an eccentric wheel and an eccentric shaft 31 connected with the eccentric wheel 30, the eccentric shaft drives the thread rolling moving plate assembly, and the specific structure and connection form can refer to the technical scheme mentioned in the background art, that is, the patent document with the application number CN202420410079.4, and the above structure does not belong to the protection range of the application.

[0045] As shown in Figure 3 , Figure 4 , Figure 5 The utility model discloses still a kind of material pushing assembly 4 for realizing the above technical scheme, it specifically includes rotating wheel 40, swing rod 41, pushing plate 43 and supporting block 44;

[0046] Wherein, the side of rotating wheel 40 is inclined surface 400;

[0047] One end side of swing rod 41 is attached with inclined surface 400, and the other end is rotatably connected with transverse rod 42, and the other end of transverse rod 42 extends into rack 8;

[0048] Pushing plate 43 is arranged on the side of rack 8 and connected with transverse rod 42;

[0049] Spring 420 is arranged on the side of rack 8, and the spring 420 is sleeved on the outer periphery of transverse rod 42;

[0050] Supporting block 44 is rotatably connected with the middle part of swing rod 41.

[0051] The power assembly 3 driving thread rolling fixed plate assembly 2 is provided with eccentric wheel 30 and eccentric shaft 31, and the rotating wheel 40 coaxially connected with eccentric wheel 30, one part of power assembly 3 is transmitted to swing rod 41, because rotating wheel 40 side has inclined surface 400, in rotating wheel 40 rotation, swing rod 41 can be forced to reciprocating swing around supporting block 44, simultaneously drive the other end of rod connected transverse rod 42 reciprocating motion, and bolt 7 in feeding channel 5 is pushed into the gap between thread rolling moving plate assembly 1 and thread rolling fixed plate assembly 2 by pushing plate 43, to achieve the purpose of feeding. Because the movement driving source of the material pushing assembly 4 and the power source of the thread rolling moving plate assembly are the same source, this way does not need to set additional air cylinder for pushing bolt 7 feeding like the thread rolling machine in prior art, and it is more economical.

[0052] The same rotating movement of the power assembly 3 is converted into the linear reciprocating movement of the pushing plate 43 by the rotating wheel 40 with the inclined surface 400 and the swing lever 41 and the transverse moving lever 42 connected therewith. The structure makes the pushing plate 43 and the movement of the thread rolling movable assembly 1 interact with each other, has the effect of synchronous beat frequency, is reasonable in structure, and is more reliable.

[0053] The rotating wheel 40 is connected with the rotating shaft of the eccentric wheel 30. In the rotation of the eccentric wheel 30, the eccentric shaft 31 not only drives the thread rolling movable assembly to move back and forth, but also forces the swing lever 41 to swing outward through the coaxially connected rotating wheel 40. Due to the setting of the swing lever 41 and the supporting block 44, a lever structure is formed, which forces the transverse moving lever 42 at the other end of the swing lever 41 to move transversely. Since the spring 420 is sleeved on the transverse moving lever 42, the spring 420 can be compressed in the movement. After the rotating wheel 40 rotates to a certain amount, the spring 420 reversely forces the pushing plate 43 and the transverse moving lever 42 to move, so that one end of the swing lever 41 always abuts against the inclined surface 400 of the rotating wheel 40. Through the above-mentioned repeated movement, the same power assembly 3 drives the thread rolling and pushing with consistent beat.

[0054] Specifically, the end of the swing lever 41 is provided with a notch 410, and at least one set of bearings 411 is arranged in the notch 410. The swing lever 41 is matched with the side of the rotating wheel 40 through the bearings 411. The end of the swing lever 41 has a fastener 412 extending into the notch 410 and matched with the bearings 411. The setting of the bearings 411 can make the swing lever 41 and the rotating wheel 40 have rolling friction, thereby reducing the wear caused by the friction between them.

[0055] The fastener 412 can be a screw.

[0056] Specifically, the bearings 411 in the embodiment are two sets, which are arranged in series.

[0057] In addition, an adjusting block 45 is arranged between the pushing plate 43 and the transverse moving lever 42. The pushing plate 43 is connected with the transverse moving lever 42 through the adjusting block 45, and a threaded rod 47 is connected between the adjusting block 45 and the pushing plate 43. The purpose of arranging the adjusting block 45 is to change the distance between the pushing plate 43 and the adjusting block 45 by replacing the threaded rod 47 with different lengths, so as to finely adjust the position of the pushing plate 43 according to the different sizes of the bolts 7, so that the center of the pushing plate 43 is opposite to the bolts 7, thereby playing a guarantee role for pushing.

[0058] In addition, in order to increase the stability of the pushing plate 43 and the adjusting block 45 in the movement, a guide rod 46 extending into the rack 8 and arranged in parallel with the transverse moving lever 42 can be connected to the side of the adjusting block 45. Guide sleeves 48 are arranged on the outer circumferences of the transverse moving lever 42 and the guide rod 46.

[0059] The surface of the inclined surface 400 is coated with a wear-resistant layer (not shown in the figure). The wear-resistant layer can effectively reduce the wear caused by long-time contact.

[0060] The horizontal moving rod 42 comprises a horizontal moving rod 421, a horizontal moving rod 422 and an adjusting sleeve 423 coaxially connecting the horizontal moving rod 421 and the horizontal moving rod 422. The horizontal moving rod 42 is composed of two detachable parts, and the horizontal moving rod 421 and the horizontal moving rod 422 with appropriate lengths can be replaced according to the actual width of the rack 8 of the thread rolling machine. The two rods are connected by the adjusting sleeve 423 which is connected by screw threads.

[0061] The above-mentioned fixed connection without specific indication can be riveting, welding, bolt 7 connection and the like, and the movable connection can be hinged connection and the like.

[0062] It should be pointed out that for those skilled in the art, without departing from the structure of the utility model, a number of modifications and improvements can be made, which should also be considered as the protection scope of the utility model, and these will not affect the effect and practicality of the utility model.
