[0002] Bolt is mechanical part, and is cylindrical fastener with nut and thread. It is a kind of fastener consisting of head and screw rod (cylinder with external thread), and needs to be matched with nut, used to fasten and connect 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 belongs to detachable connection. Thread grinding machine is a thread processing machine tool using shaped grinding wheel as grinding 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 thread rolling machine, which comprises a bottom plate, and symmetrical inclined support frames are 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 fixedly connected above the bottom plate, a motor mounting plate is fixed 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 rotating wheel to rotate synchronously through the stepping motor, drives the two sliding mounting plates to reciprocate through the connecting arm, makes the second thread rolling plate on one side of the two sliding mounting plates reciprocate synchronously, and thus synchronously threads the two bolts to be processed between the first thread rolling plate and the second thread rolling plate.

[0004] However, the existing thread rolling machine, although realizing the function of effectively producing and processing bolts, still has some deficiencies. The push block for entering the two thread rolling 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 thread rolling 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, and the reliability needs to be improved, and the economy is weak. UTILITY MODEL CONTENTS

[0008] A push material plate is arranged on the side of the rack and connected with the horizontal moving rod;

[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] Further, a groove is formed in the end of the swing rod, and a ball is embedded in the groove, and the swing rod is matched with the side part of the rotating wheel through the ball.

[0013] Further, a guide rod is connected to the side part of the adjusting block and extends into the frame and is arranged in parallel with the transverse rod.

[0014] Further, a threaded rod is connected between the adjusting block and the pushing plate.

[0015] Further, a guide sleeve is arranged on the outer periphery of the transverse rod and the guide rod.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The power assembly for driving the thread rolling fixed plate assembly is provided with an eccentric wheel and an eccentric shaft, a rotating wheel coaxially connected with the eccentric wheel transmits part of power of the power assembly to the swing rod, the side part of the rotating wheel has an inclined surface, and the swing rod is forced to reciprocating swing around the supporting block in the rotation of the rotating wheel, the transverse rod connected to the other end of the swing rod is driven to reciprocate, and the bolt in the feeding channel is pushed into the gap between the thread rolling movable plate assembly and the thread rolling fixed plate assembly through the pushing plate, so that the feeding purpose is achieved. Since the movement driving source of the pushing assembly and the power source of the thread rolling movable and fixed assembly are the same source, the thread rolling machine does not need to additionally arrange the cylinder for pushing and feeding the bolt, and the economy is better.

[0029] As shown in 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.

[0030] Among them, thread rolling fixed plate assembly 2 and thread rolling movable plate assembly 1 are arranged opposite parallel, and the interval width between the two is not less than the diameter of the screw column to be rolled.

[0031] Power assembly 3 is used to drive thread rolling movable plate assembly 1 to reciprocate linear motion relative to thread rolling fixed plate assembly 2.

[0032] The pushing assembly 4 is arranged at the side of the thread rolling fixed plate assembly 2;

[0033] A feeding channel 5 is arranged at 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 gap between the thread rolling movable plate assembly 1 and the thread rolling fixed plate assembly 2;

[0034] 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, thereby matching the size of the bolts 7 to be thread rolled, and having stronger adaptability.

[0035] Specifically, as shown in the figure, Figure 6 The thread rolling fixed plate assembly 2 includes 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, which drives the fixed plate seat 20 to move in the gap width direction, so that the fixed plate body 21 and the thread rolling movable plate assembly 1 are close to or away from each other.

[0036] The thread rolling fixed plate assembly 2 further includes a sliding rail 23 connected to the fixed plate seat 20.

[0037] The sliding rail 23 is arranged to make the thread rolling fixed plate assembly 2 move more smoothly in the transverse direction, and has better smoothness.

[0038] 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 formed in the fixed plate seat 20 to facilitate the addition of lubricating liquid.

[0039] The adjusting mechanism 22 in the embodiment can be driven by a screw assembly, and its structure includes 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 adopt other structural forms, such as a telescopic air cylinder.

[0040] 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 specifically.

[0041] In addition, a discharge hopper 6 is arranged at the side of the thread rolling fixed plate assembly 2, which can guide the thread rolled bolts 7, so as to facilitate the centralized collection of the bolts 7 for the next processing procedure.

[0042] The above-mentioned thread rolling moving plate assembly 1, power assembly 3 and 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 thread rolling moving plate assembly is driven through the eccentric shaft, and the specific structure and connection form can be referred to the technical scheme mentioned in the background art, that is, the patent literature with the application number CN202420410079.4, and the above-mentioned structure does not belong to the protection range of the present application.

[0043] As shown in Figure 3 、 Figure 4 、 Figure 5 The utility model discloses a kind of pushing assembly 4 for realizing the above technical solution, it specifically includes rotating wheel 40, swing rod 41, pushing plate 43 and supporting block 44.

[0044] Among them, the side of rotating wheel 40 is inclined surface 400;

[0045] 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;

[0046] Pushing plate 43 is arranged at the side of rack 8 and connected with transverse rod 42.

[0047] Spring 420 is arranged at the side of rack 8, which is sleeved on the outer periphery of transverse rod 42.

[0048] Supporting block 44 is rotatably connected with the middle part of swing rod 41.

[0049] 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 transmits part of power of power assembly 3 to swing rod 41, and due to the inclined surface 400 on the side of rotating wheel 40, swing rod 41 is forced to reciprocate around supporting block 44 during the rotation of rotating wheel 40, and the transverse rod 42 connected with the other end of swing rod 41 reciprocates, and the 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 through pushing plate 43, to achieve the purpose of feeding. Since the movement driving source of the pushing assembly 4 and the power source of the thread rolling moving plate assembly are the same source, this way does not need to additionally set the air cylinder for pushing and feeding the bolt 7 like the existing thread rolling machine, and it is more economical.

[0050] Due to the use of rotating wheel 40 with inclined surface 400 and swing rod 41 and transverse rod 42 cooperating with it, the rotary motion of the same power assembly 3 is converted into the linear reciprocating motion of pushing plate 43, and this structure makes the movement of pushing plate 43 and thread rolling moving plate assembly 1 exist mutual linkage, has the effect of beat frequency synchronization, and the structure is reasonable, and it is more reliable.

[0051] 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 reciprocating movement of the twisting member assembly, but also forces the swinging of the rotating wheel 40 connected coaxially, so that the swinging rod 41 forms a lever structure due to the arrangement of the supporting block 44, and forces the transverse movement of the transverse rod 42 at the other end of the swinging rod 41. Since the spring 420 is sleeved on the transverse rod 42, the spring 420 is compressed in this movement. After the rotating wheel 40 rotates to a certain amount, the spring 420 reversely forces the movement of the material pushing plate 43 and the transverse rod 42, so that one end of the swinging rod 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 twisting, material pushing and consistent beat effect is achieved.

[0052] Specifically, the end of the swinging rod 41 is provided with a groove 410, and the groove 410 is embedded with a ball 411. The swinging rod 41 is matched with the side of the rotating wheel 40 through the ball 411. The arrangement of the ball 411 can make the swinging rod 41 and the rotating wheel 40 have rolling friction, so as to reduce the wear caused by the friction between them. In addition, other forms can also be used to reduce the wear between them, such as using a bearing to replace the ball 411.

[0053] In addition, an adjusting block 45 is arranged between the material pushing plate 43 and the transverse rod 42. The material pushing plate 43 is connected with the transverse rod 42 through the adjusting block 45, and a threaded rod 47 is connected between the adjusting block 45 and the material pushing plate 43. The purpose of arranging the adjusting block 45 is to change the distance between the material 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 material pushing plate 43 according to the different sizes of the bolt 7, so that the center of the material pushing plate 43 is opposite to the bolt 7, and the material pushing plate 43 plays a guarantee role.

[0054] In addition, in order to increase the stability of the material pushing plate 43 and the adjusting block 45 in the movement, a guide rod 46 is connected on the side of the adjusting block 45 and extends into the rack 8 and is arranged parallel to the transverse rod 42. Guide sleeves 48 are arranged on the outer circumferences of the transverse rod 42 and the guide rod 46.

[0055] The above-mentioned fixed connection without specification can be riveting, welding, bolt connection and the like, and the movable connection can be hinged connection and the like.

[0056] It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application.
