[0020] The utility model is specifically introduced below in conjunction with the accompanying drawings and embodiments.

[0021] Reference Figures 1 to 7The present embodiment is a high-efficiency three-axis thread rolling machine, comprising a base 1, a thread rolling mechanism 2, and a transmission mechanism 3. The top of the base 1 is concave to form a placement groove 1a, and the front and rear side walls of the upper part of the base 1 are respectively provided with a first through hole 1b and a second through hole 1c connected to the placement groove 1a. The thread rolling mechanism 2 comprises a fixed seat 2a arranged in the placement groove 1a, and one side of the front end surface of the fixed seat 2a is provided with two first mounting holes 2a-1 spaced apart in the vertical direction, and the two first mounting holes 2a-1 are respectively fixed with first bearings, and the inner rings of the two first bearings are respectively fixed with first rotating shafts 2a-3, and one end of the two first rotating shafts 2a-3 is respectively fixed with first rolling wheels 2a-4 and second rolling wheels 2a-5 passing through the first through holes 1b. A rotating seat 2b is provided on one side of the fixed seat 2a, and the lower part of the rotating seat 2b is rotatably connected to the inner wall of the placement groove 1a through a rotating rod 2b-1. A second mounting hole 2b-2 is provided on one side of the front end surface of the rotating seat 2b. The second mounting hole 2b- 2 is fixed with a second bearing, a second rotating shaft 2b-4 is fixed in the inner ring of the second bearing, a third rolling wheel 2b-5 passing through the first through hole 1b is arranged at one end of the second rotating shaft 2b-4, two supporting plates 2c are arranged on the side wall of the base 1 close to the rotating seat 2b, a third rotating shaft 2c-1 is rotatably arranged between the upper parts of the two supporting plates 2c, a cam 2c-2 is arranged in the middle part of the third rotating shaft 2c-1, a supporting column 2d is arranged on the side of the rotating seat 2b facing the cam 2c-2, a fixing frame 2d-1 is arranged at the end of the supporting column 2d, a roller 2d-2 that contacts with the cam 2c-2 is rotatably arranged in the fixing frame 2d-1, a straight plate 2e is arranged between the middle parts of the two supporting plates 2c, a spring 2e-1 is arranged between the straight plate 2e and the rotating seat 2b, and the transmission mechanism 3 includes a first transmission component 3a that drives the second rotating shaft 2b-4 and the two first rotating shafts 2a-3 to rotate, and a second transmission component 3b that drives the third rotating shaft 2c-1 to rotate.

[0022] The first transmission component 3a in the transmission mechanism 3 drives the second rotating shaft 2b-4 and two first rotating shafts 2a-3 to rotate, thereby driving the first rolling gear 2a-4 and the second rolling gear 2a-5 on the fixed seat 2a, and the third rolling gear 2b-5 on the rotating seat 2b will also rotate simultaneously. When the second transmission component 3b drives the third rotating shaft 2c-1 to rotate, the outer surface of the cam 2c-2 in the middle of the third rotating shaft 2c-1 can press against the roller 2d-2 at the end of the support column 2d during rotation, so that the rotating seat 2b is pushed by the support column 2d and thus rotates, causing the third rolling gear 2b-5 to approach the first rolling gear 2a-4 and the second rolling gear 2a-5. When the third rolling gear 2b-5 is at the closest point to the first rolling gear 2a-4 and the second rolling gear 2a-5, a tapping gap is formed between the third rolling gear 2b-5, the first rolling gear 2a-4, and the second rolling gear 2a-5. At this time, the spring 2e-1 between the straight plate 2e and the rotating seat 2b is in a tensioned state. As the third rotating shaft 2c-1 rotates, the outer surface of the cam 2c-2 in the middle of the third rotating shaft 2c-1 begins to disengage from the contact with the roller 2d-2 at the end of the support column 2d. At the same time, the rotating seat 2b slowly rotates back under the pulling force of the spring 2e-1, causing the third rolling gear 2b-5 to move away from the first rolling gear 2a-4 and the second rolling gear 2a-5.

[0023] In this embodiment, the first transmission component 3a includes a transmission seat 3a-1 provided on one side of the base 1. The transmission seat 3a-1 is provided with two third mounting holes 3a-2 at positions corresponding to the two first mounting holes 2a-1. The two first rotating shafts 2a-3 respectively pass through the second through hole 1c and the two third mounting holes 3a-2. Third bearings are respectively arranged in the two third mounting holes 3a-2, and the outer walls of the two first rotating shafts 2a-3 are respectively fixed in the inner rings of the two third bearings.

[0024] In this embodiment, the transmission seat 3a-1 is provided with a fourth mounting hole 3a-4 at a position on one side of the two third mounting holes 3a-2. A fourth bearing is fixed in the fourth mounting hole 3a-4. A fourth rotating shaft 3a-6 is fixed in the inner ring of the fourth bearing. One end of the fourth rotating shaft 3a-6 facing the base 1 is provided with a first U-shaped mounting bracket 3a-7. The end of the second rotating shaft 2b-4 facing the transmission seat 3a-1 passes through the second through hole 1c and is provided with a second U-shaped mounting bracket 3a-8. A transmission member 3c is arranged between the fourth rotating shaft 3a-6 and the second rotating shaft 2b-4.

[0025] When the fourth rotating shaft 3a-6 rotates, the second rotating shaft 2b-4 can be driven to rotate through the transmission member 3c, and then the third rolling gear 2b-5 starts to rotate.

[0026] In this embodiment, the transmission member 3c includes a plug-in cylinder 3c-1 and a plug-in rod 3c-2 slidably inserted into the plug-in cylinder 3c-1. A clamping groove 3c-3 is circumferentially formed on the outer wall of the plug-in rod 3c-2, and a clamping strip 3c-4 slidably clamped in the clamping groove 3c-3 is provided on the inner wall of the plug-in cylinder 3c-1.

[0027] Since the inner wall of the plug-in cylinder 3c-1 is provided with a clamping strip 3c-4 slidably clamped in the clamping groove 3c-3, the rotation of the plug-in cylinder 3c-1 can drive the rotation of the plug-in rod 3c-2. At the same time, a displacement change can also occur between the plug-in rod 3c-2 and the plug-in cylinder 3c-1 during rotation.

[0028] In this embodiment, a third U-shaped mounting bracket 3c-5 is provided at one end of the plug-in cylinder 3c-1 facing the fourth rotating shaft 3a-6, and a fourth U-shaped mounting bracket 3c-6 is provided at one end of the plug-in rod 3c-2 facing the second rotating shaft 2b-4. The third U-shaped mounting bracket 3c-5 and the first U-shaped mounting bracket 3a-7 are rotatably connected by a first cross column 3c-8, and the fourth U-shaped mounting bracket 3c-6 and the second U-shaped mounting bracket 3a-8 are rotatably connected by a second cross column 3c-9.

[0029] When the fourth rotating shaft 3a-6 rotates, power is transmitted between the fourth rotating shaft and the plug-in cylinder 3c-1 through the third U-shaped mounting bracket 3c-5, the first U-shaped mounting bracket 3a-7, and the first cross column 3c-8, causing the plug-in cylinder 3c-1 to start rotating. The plug-in cylinder 3c-1 can drive the rotation of the plug-in rod 3c-2. Power is transmitted between the plug-in rod 3c-2 and the second rotating shaft 2b-4 through the fourth U-shaped mounting bracket 3c-6, the second U-shaped mounting bracket 3a-8, and the second cross column 3c-9, causing the second rotating shaft 2b-4 to start rotating, thereby driving the rotation of the third rolling gear 2b-5. When the rotating seat 2b rotates, the distance between the end of the second rotating shaft 2b-4 on the rotating seat 2b and the end of the fourth rotating shaft 3a-6 on the transmission seat 3a-1 will continuously change, and a displacement can occur between the plug-in cylinder 3c-1 and the plug-in rod 3c-2. Therefore, the fourth rotating shaft can drive the second rotating shaft 2b-4 to rotate through the transmission member 3c.

[0030] In this embodiment, a first gear 3a-9 is provided at one end of the fourth rotating shaft 3a-6 away from the base 1. Second gears 3a-10 and third gears 3a-11 are respectively provided at one end of the two first rotating shafts 2a-3 away from the base 1. The first gear 3a-9, the second gear 3a-10, and the third gear 3a-11 are connected by a first chain 3a-12. A support frame 3a-13 is provided on one side of the transmission seat 3a-1, and a first rotating motor 3a-14 is provided on the support frame 3a-13. The output end of the first rotating motor 3a-14 is drivingly connected to the end of one of the two first rotating shafts 2a-3.

[0031] Turn on the first rotating motor 3a-14, and the first rotating motor 3a-14 drives one of the two first rotating shafts 2a-3 to rotate, and then drives the first gear 3a-9, the second gear 3a-10 and the third gear 3a-11 to rotate through the first chain 3a-12.

[0032] In this embodiment, the second transmission assembly 3b includes a second rotating motor 3b-1 arranged on one side of the two support plates 2c, a fourth gear 3b-2 is arranged at the output end of the second rotating motor 3b-1, and a fifth gear 3b-3 is arranged after the end of the third rotating shaft 2c-1 close to the second rotating motor 3b-1 passes through the support plate 2c, and the fourth gear 3b-2 and the fifth gear 3b-3 are connected by a second chain 3b-4.

[0033] The second rotating motor 3b-1 is turned on, and the second rotating motor 3b-1 drives the fourth gear 3b-2 to rotate, and the fourth gear 3b-2 drives the fifth gear 3b-3 to rotate through the second chain 3b-4, thereby driving the third rotating shaft 2c-1 to rotate.

[0034] Working principle: Turn on the first rotating motor 3a-14. The first rotating motor 3a-14 drives the rotation of one of the two first rotating shafts 2a-3. Then, through the first chain 3a-12, it drives the rotation of the first gear 3a-9, the second gear 3a-10, and the third gear 3a-11. Since the first gear 3a-9, the second gear 3a-10, and the third gear 3a-11 all start to rotate, the fourth rotating shaft 3a-6 and the two first rotating shafts 2a-3 are both rotating. The rotation of the two first rotating shafts 2a-3 drives the rotation of the first rolling wheel 2a-4 and the second rolling wheel 2a-5. When the fourth rotating shaft 3a-6 rotates, power is transmitted between the fourth rotating shaft and the insertion cylinder 3c-1 through the third U-shaped mounting bracket 3c-5, the first U-shaped mounting bracket 3a-7, and the first cross column 3c-8, causing the insertion cylinder 3c-1 to also start rotating. The insertion cylinder 3c-1 can drive the rotation of the insertion rod 3c-2. Power is transmitted between the insertion rod 3c-2 and the second rotating shaft 2b-4 through the fourth U-shaped mounting bracket 3c-6, the second U-shaped mounting bracket 3a-8, and the second cross column 3c-9, causing the second rotating shaft 2b-4 to also start rotating, and then driving the rotation of the third rolling wheel 2b-5. Turn on the second rotating motor 3b-1. The second rotating motor 3b-1 drives the rotation of the fourth gear 3b-2. The fourth gear 3b-2 drives the rotation of the fifth gear 3b-3 through the second chain 3b-4, and then drives the rotation of the third rotating shaft 2c-1. When the third rotating shaft 2c-1 rotates, the outer surface of the cam 2c-2 in the middle of the third rotating shaft 2c-1 can push against the roller 2d-2 at the end of the support column 2d when rotating, causing the rotating seat 2b to be pushed by the support column 2d and thus rotate. When the rotating seat 2b rotates, the distance between the end of the second rotating shaft 2b-4 on the rotating seat 2b and the end of the fourth rotating shaft 3a-6 on the transmission seat 3a-1 will continuously change, and relative sliding can occur between the insertion cylinder 3c-1 and the insertion rod 3c-2. Therefore, the fourth rotating shaft can drive the second rotating shaft 2b-4 to rotate through the transmission member 3c. When the rotating seat 2b rotates close to the fixed seat 2a, the third rolling wheel 2b-5 also gradually approaches the first rolling wheel 2a-4 and the second rolling wheel 2a-5. When the third rolling wheel 2b-5 reaches the closest point to the first rolling wheel 2a-4 and the second rolling wheel 2a-5, a tapping gap is formed between the third rolling wheel 2b-5, the first rolling wheel 2a-4, and the second rolling wheel 2a-5. At this time, the spring 2e-1 between the straight plate 2e and the rotating seat 2b is in a taut state. Since the workpiece to be processed can be supported by three support points provided by the first rolling wheel 2a-4, the second rolling wheel 2a-5, and the third rolling wheel 2b-5 in the tapping gap, when the workpiece is rolled by the first rolling wheel 2a-4, the second rolling wheel 2a-5, and the third rolling wheel 2b-5 in the tapping gap, the worker can release the workpiece and take the unprocessed workpiece waiting for processing. As the third rotating shaft 2c-1 rotates,The outer curved surface of the cam 2c-2 in the middle of the third rotating shaft 2c-1 begins to break away from the resistance of the roller 2d-2 at the end of the support column 2d. At the same time, the rotating seat 2b slowly rotates back under the pulling force of the spring 2e-1, so that the third rolling wheel 2b-5 moves away from the first rolling wheel 2a-4 and the second rolling wheel 2a-5, and the workpiece in the tapping gap falls freely to the bottom. The worker holds the unprocessed workpiece and places it between the first rolling wheel 2a-4 and the second rolling wheel 2a-5, waiting for the next approach of the third rolling wheel 2b-5.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
