The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] See also Figure 1 The figure is a schematic diagram of the structure of a pancake machine tool drive system assembly provided by a preferred embodiment of the present application. Figure 1 In the illustrated embodiment, it includes a base 1 and a driving joint 2 arranged on the base 1 .

[0038] The base 1 of the driving system is formed by welding steel plates and has sufficient strength and stability; the driving joint 2 is arranged on the base 1, and the pancake machine tool is rotated by the motor. The end of the driving joint 2 is provided with a male connector 3 for connecting to a female connector 4 of various tooling.

[0039] The male connector 3 is composed of a male connecting disk 30 and a piston body 31. The piston body 31 is movably installed in the male connecting disk 30, and has two upper and lower closed floating spaces in the male connecting disk 30. A first spring 32 connecting the piston body 31 and the male connecting disk 30 is provided in the lower closed floating space, so that the connection between the piston body 31 and the male connecting disk 30 is more stable. The upper and lower sides of the outer wall of the male connecting disk 30 are respectively provided with an upper air port and a lower air port connected to the upper and lower closed floating spaces (wherein an upper air pipe 305 is provided on the upper air port, and a lower air pipe 306 is provided on the lower air port, see Figure 2 ), which is used to connect to the air source and control the piston body 31 to float up and down in the male connecting disk 30.

[0040] The male connector 30 has a protruding portion 301, and the side wall of the protruding portion 301 is provided with a plurality of first through holes 302 and a plurality of second through holes 303. A plurality of first balls 33 for locking the female connector 4 are movably disposed in the first through holes 302 in a one-to-one correspondence, and a plurality of second balls 34 for positioning the female connector 4 are movably disposed in the second through holes 303 in a one-to-one correspondence.

[0041] The outer wall of the piston body 31 is provided with a first receiving groove 310 and a second receiving groove 311 for receiving the second ball 34. The first receiving groove 310 includes a first receiving surface 3101 for receiving the first ball 33 and a first contact surface 3102 for pushing the first ball 33. When the piston body 31 floats downward, the first ball 33 partially extends out of the first through hole 302 under the action of the first contact surface 3102, thereby being locked on the inner wall of the female connector 4, and the second ball 34 partially retracts back into the second through hole 303 under the action of the second receiving groove 311. When the piston body 31 floats upward, the first ball 33 enters the first receiving surface 3101 from the first contact surface 3102, causing the first ball 33 to partially retract into the first through hole 302, thereby releasing the lock on the female connector 4. The second ball 34 partially extends out of the second through hole 303 under the action of the second receiving groove 311 (due to the slight retraction, it will not cause the locking of the female connector 4, and only serves as a positioning).

[0042] It is understandable that if Figure 3 As shown, Figure 3Schematic diagram of the structure of the female connector 4, whose inner wall has a locking groove 401 and a positioning groove 402, wherein the male connector 3 can be divided into two types of balls, one type of ball is the first ball 33, which is controlled by the up and down movement of the piston body 31 to control the extension and contraction so that the male connector 3 can grab the female connector 4, and the second type of ball is the second ball 34, which is controlled by the up and down movement of the piston body 31 to fine-tune the positioning of the male connector 3 and the female connector 4. The first ball 33 and Figure 3 The locking groove 401 of the female connector 4 shown in the figure cooperates with the second ball Figure 3 The positioning groove 402 of the female connector 4 is shown to cooperate.

[0043] Specifically, by setting multiple groups of first through holes 302 and multiple groups of second through holes 303, and the movable setting of the first ball 33 and the second ball 34, the female connector 4 can be accurately positioned on the protrusion 301, thereby ensuring the stability and firmness of the connector and avoiding unstable phenomena such as displacement or shaking of the connector during operation.

[0044] Furthermore, the positioning method using the first ball 33 and the second ball 34 can achieve high-precision positioning of the female connector 4, thereby avoiding deviation or error of the connector during the connection process and improving processing accuracy and connection quality.

[0045] Finally, by adopting the positioning method of using the first ball 33 to grab the female connector 4 and the second ball 34 to position the female connector 4, the connector can be easily and quickly loaded and unloaded, saving operation time and labor costs and improving work efficiency.

[0046] Due to the combination of the above-mentioned technical features, the pancake machine tooling drive system has good connection, locking and positioning functions, and can achieve stable up and down movement, so it can be applied to the production and manufacturing of various types of pancake machines.

[0047] Preferably, the first through holes 302 and the second through holes 303 are arranged crosswise and equidistantly, and the corresponding first rolling balls 33 and second rolling balls 34 are also arranged crosswise and equidistantly, and the number of the first rolling balls 33 and the second rolling balls 34 are three groups respectively.

[0048] Preferably, a positioning column 35 is further provided on the end surface of the male connection plate 30, and the positioning column 35 is used to cooperate with the positioning groove 402 on the female connector 4. The second positioning is achieved by the positioning column 35 and the positioning groove 402, further improving the position accuracy of the connection.

[0049] Preferably, the male connector 30 is provided with a plurality of air inlet holes 304 along the end surface, and the number and position of the air inlet holes 304 can be determined according to specific needs, for example, the air inlet holes 304 are evenly arranged along the end surface. The air inlet holes 304 can be circular, rectangular or other shapes, and their diameter or size can also be determined according to needs.

[0050] The male connector plate 30 is provided with air outlet holes along the outer wall corresponding to the plurality of air inlet holes 304. The number and position of the air outlet holes correspond to the air inlet holes. Figure 2 As shown, the air outlet is provided with an air pipe joint 307. The air outlet can be circular, rectangular or in other shapes, and its diameter or size can also be determined as required.

[0051] An air passage communicating with the air inlet 304 and the air outlet is provided, and the shape of the air passage can be determined according to specific needs. The length and diameter of the air passage can also be determined according to needs to meet the required gas flow rate.

[0052] An air blocking elastic member 36 is provided in the air passage connected between the air inlet 304 and the air outlet. The air blocking elastic member 36 may be a spring, a rubber gasket, a rubber ball, etc. Specifically, Figure 4 , shown are a sphere 360 ​​and a second spring 361. Under the effect of elasticity, the air-blocking elastic member 36 can close the airway connecting the air inlet 304 and the air outlet, thereby preventing the gas from flowing through the airway.

[0053] When the male connector 30 is used, the gas flow in the air inlet 304 can be controlled so that the gas enters the connected airway through the air inlet 304, passes through the air blocking elastic member 36, and finally is discharged from the airway connected to the air outlet. When the gas flow needs to be stopped, the air blocking elastic member 36 will re-close the airway under the action of elasticity to prevent the gas from continuing to flow. For example, when the male connector 3 is connected to the female connector 4, the protruding part on the female connector 4 pushes the air blocking elastic member 36 to open the airway.

[0054] The male connector 3 further includes a PIN male connector 37 , which is disposed on the male connector disk 30 . The PIN male connector 37 is used to electrically connect to the PIN female connector on the female connector 4 .

[0055] like Figure 4 As shown, sealing rings 38 are provided on the piston body 31 above the upper enclosed floating space, below the lower enclosed floating space, and in between to meet the sealing requirements.

[0056] Those skilled in the art will understand that Figure 1-Figure 6 The specific structure of a pancake machine tooling drive system shown in the figure does not constitute a limitation of the pancake machine tooling drive system. The pancake machine tooling drive system may include more or fewer components than shown in the figure. Some components are not necessary components of the pancake machine tooling drive system and can be omitted or combined as needed without changing the essence of the invention.

[0057] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present application is limited by the attached claims rather than the above description, so it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims in the present application.
