[0021] Compared with the prior art, the beneficial effect of the present invention is: This new energy vehicle drive shaft turning device for quickly clamping workpieces

[0022] (1) This device is designed to solve the problems that the existing lathe for the end cover of an automotive drive shaft generates a large amount of dust-containing gas during the turning process, and during turning, the tool generates a large amount of heat due to intense friction with the workpiece. If the temperature is not lowered in a timely manner, it is easy to cause tool damage. Inside the support box, there is a first electric telescopic rod, and the first electric telescopic rod can drive the lifting turntable to move. Above the support box, there is a processing table, and the support box and the processing table are provided with moving grooves that cooperate with the lifting turntable. On the top of the processing table, there is a fixing frame, and above the fixing frame, there is an end cover clamping mechanism.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1-7 , the present invention provides a technical solution: a turning device for a drive shaft of a new energy vehicle for quickly clamping a workpiece. A first electric telescopic rod 101 is arranged inside a support box 1, and the first electric telescopic rod 101 can drive a lifting turntable 102 to move. A processing table 2 is installed above the support box 1, and moving grooves for cooperating with the lifting turntable 102 are provided on the support box 1 and the processing table 2.

[0034] Specifically, a water collecting tank 1011 is installed on one side of the first electric telescopic rod 101 inside the support box 1, and the bottom of the water collecting tank 1011 is connected to the inner bottom of the support box 1 through a support arm 1012.

[0035] Specifically, a movable push scraping plate 8 is installed on one side inside the support box 1. The movable push scraping plate 8 includes a push scraping plate 801, and the push scraping plate 801 is installed at the bottom of a first fixing block 802. The first fixing block 802 is connected to a second fixing block 804 through a second electric telescopic rod 803. A third electric telescopic rod 805 for driving the second fixing block 804 to move up and down is arranged inside the support box 1. The second fixing block 804 is slidably connected to the inner wall of the support box 1 to improve the stability of the second fixing block 804 during movement.

[0036] When the lifting turntable 102 and the end cover 308 move into the support box 1 under the action of the first electric telescopic rod 101, the height of the push scraping plate 801 is adjusted by the third electric telescopic rod 805 so that the bottom of the push scraping plate 801 just contacts the top of the end cover 308. At this time, the second electric telescopic rod 803 is turned on to drive the push scraping plate 801 to move, thereby scraping the water stains on the surface of the end cover 308 into the water collecting tank 1011 for collection. At the same time, by adjusting the height of the push scraping plate 801, the second electric telescopic rod 803 can push the end cover 308 to move through the push scraping plate 801.

[0037] Specifically, a fixing frame 201 is provided on the top of the processing table 2, and an end cover clamping mechanism 3 is installed above the fixing frame 201. The end cover clamping mechanism 3 includes an installation groove 301, and two groups of moving blocks 302 are slidably arranged inside the installation groove 301. The moving blocks 302 are connected to a bidirectional lead screw mechanism 303 rotatably arranged inside the installation groove 301, and the bidirectional lead screw mechanism 303 is connected to an acceleration driving mechanism 304. The moving blocks 302 are connected to a cross bar 306 through a transmission rod 305, and the cross bar 306 is slidably connected inside an opening cylinder 307. A clamping plate 309 for cooperating with the end cover 308 is installed at one end of the cross bar 306.

[0038] Further explanation, the acceleration driving mechanism 304 includes a driving motor 3041, and the driving motor 3041 can drive a first gear 3043 arranged inside a protective box 3042 to rotate. The first gear 3043 meshes with a second gear 3044. The size of the first gear 3043 is larger than that of the second gear 3044. Therefore, when the first gear 3043 rotates, it can drive the second gear 3044 to rotate at an accelerated speed. The second gear 3044 is installed on the outer side of a rotating rod 3045. A third gear 3046 is arranged on the outer side of the rotating rod 3045, and the third gear 3046 meshes with a fourth gear 3047. The size of the third gear 3046 is larger than that of the fourth gear 3047. Therefore, when the third gear 3046 rotates, it can drive the fourth gear 3047 to rotate at an accelerated speed. The fourth gear 3047 is installed on the outer side of the bidirectional lead screw mechanism 303.

[0039] Further explanation, moving through grooves for cooperating with the transmission rod 305 are formed on the fixing frame 201 and the opening cylinder 307.

[0040] When it is necessary to limit and clamp the end cover 308 placed above the lifting turntable 102, the driving motor 3041 is turned on. Under the action of the driving motor 3041, the first gear 3043 rotates. The first gear 3043 drives the second gear 3044 and the rotating rod 3045 to rotate at an accelerated speed. The rotating rod 3045 drives the fourth gear 3047 and the bidirectional lead screw mechanism 303 to rotate at an accelerated speed through the third gear 3046. Under the action of the rotation of the bidirectional lead screw mechanism 303, the two groups of moving blocks 302 continuously approach, so as to drive the clamping plate 309 to continuously approach through the transmission rod 305 and the cross bar 306, thereby clamping and limiting the end cover 308.

[0041] Specifically, a movable turning mechanism 4 is provided at the inner top of the fixing frame 201. The movable turning mechanism 4 includes a transverse groove 401, and a first driving block 402 is slidably arranged inside the transverse groove 401. The first driving block 402 is connected to an electric lead screw mechanism 403 rotatably arranged inside the transverse groove 401. A longitudinal groove 404 is installed at the bottom of the first driving block 402. A second driving block 405 is slidably arranged inside the longitudinal groove 404, and a fourth electric telescopic rod 406 for driving the second driving block 405 to move is installed inside the longitudinal groove 404. The bottom of the second driving block 405 is connected to a positioning groove 408 through a fifth electric telescopic rod 407, and a turning motor 409 is installed inside the positioning groove 408. The turning motor 409 can drive a turning tool 4091 to rotate. When it is necessary to adjust the turning position, the electric lead screw mechanism 403 is turned on. Under the action of the electric lead screw mechanism 403, the first driving block 402 moves inside the transverse groove 401, thereby driving the turning tool 4091 to move horizontally. The fourth electric telescopic rod 406 is turned on. Under the action of the fourth electric telescopic rod 406, the second driving block 405 moves inside the longitudinal groove 404, thereby driving the turning tool 4091 to move longitudinally. The fifth electric telescopic rod 407 can adjust the height where the turning tool 4091 is located.

[0042] Specifically, an annular spray pipe 5 is installed outside the positioning groove 408. A plurality of groups of spray heads 501 are installed at the bottom of the annular spray pipe 5. One side of the annular spray pipe 5 is connected to a joint 503 through an elastic delivery pipe 502. The other end of the joint 503 is connected to a water pump 505 through a first connecting pipe 504, and the water pump 505 is connected to the inside of a cooling box 6 through a second connecting pipe. An inlet is provided on one side of the cooling box 6. A low-temperature conduction plate 601 is arranged inside the cooling box 6, and the low-temperature conduction plate 601 is connected to a refrigeration plate 602. The refrigeration plate 602 is installed on the refrigerating surface side of a semiconductor refrigeration sheet 603, and the heating surface of the semiconductor refrigeration sheet 603 is connected to a heat conduction plate 604. The other side of the heat conduction plate 604 is connected to a heat dissipation fan 606 through a heat dissipation plate 605, and the heat dissipation fan 606 is located inside an installation box 607. The installation box 607 is connected to an air distribution plate 609 arranged inside the support box 1 through an air delivery pipe 608, and the air distribution plate 609 is located above a conveying mechanism 7 installed inside the support box 1.

[0043] In use, the end cover 308 is placed above the lifting turntable 102 and clamped and limited by the end cover clamping mechanism 3. After clamping, the movable turning mechanism 4 can perform turning processing on it. During turning, the semiconductor refrigerating sheet 603 is turned on. The refrigerating surface of the semiconductor refrigerating sheet 603 conducts low temperature to the inside of the cooling box 6 through the refrigerating plate 602 and the low-temperature conduction plate 601, so as to cool the liquid in the cooling box 6. The cooled liquid enters the second connecting pipe, the first connecting pipe 504, the elastic conveying pipe 502, and the annular spray pipe 5 in sequence under the action of the water pump 505 and finally sprays out from the spray head 501, thereby reducing the dust content in the gas and also cooling the turning tool 4091. The turned end cover 308 enters the support box 1 under the action of the first electric telescopic rod 101. The movable push scraper 8 scrapes and collects the water stains on the surface of the end cover 308. At the same time, the movable push scraper 8 can also push the end cover 308 to move above the conveying mechanism 7. The heat generated by the semiconductor refrigerating sheet 603 forms hot air through the heat dissipation fan 606 and enters the air conveying pipe 608 in sequence and finally sprays out from the air distribution plate 609 and acts on the surface of the end cover 308 conveyed above the conveying mechanism 7, thereby performing an air-drying operation on the end cover 308.
