[0055] See also Figures 1 to 3 In this embodiment, a turntable-type workpiece transfer device is proposed, which includes a central axis 1, a turntable 2, multiple first clamping members 3, multiple second clamping members 4, a pushing member 5 and an elastic member 6. The central axis 1 is arranged in the vertical direction; the turntable 2 is rotatably connected to the central axis 1, and the turntable 2 can rotate around the central axis 1; multiple first clamping members 3 are evenly distributed on the top of the turntable 2; multiple second clamping members 4 and multiple second clamping members 4 are arranged one-to-one correspondingly to the multiple first clamping members 3, and any second clamping member 4 is connected to the turntable 2 along the radial direction of the turntable 2; the pushing member 5 is arranged on the central axis 1 to push the second clamping member 4 away from the first clamping member 3; the elastic member 6 is arranged between the first clamping member 3 and the second clamping member 4, and can generate elastic deformation when the second clamping member 4 moves away from the first clamping member 3, so as to have elastic potential energy to make the second clamping member 4 approach the first clamping member 3 and clamp the workpiece 100.

[0056] It can be understood that when clamping the workpiece 100, the pushing member 5 pushes the second clamping member 4 to move in the direction away from the first clamping member 3, and then the workpiece 100 is placed between the first clamping member 3 and the second clamping member 4, the pushing member 5 is disengaged from the second workpiece 100, and under the action of the elastic member 6, the second clamping member 4 can be moved closer to the first clamping member 3 to facilitate clamping the workpiece 100, and under the action of the elastic potential energy of the elastic member 6, the first clamping member 3 and the second clamping member 4 can always be in a clamping state with the workpiece 100 during the rotation of the turntable 2. Such a setting can avoid the setting of multiple lines and multiple air paths, thereby reducing the production cost of the workpiece 100.

[0057] Furthermore, the first clamping member 3 includes a first clamping block 31 and a first connecting member 32, which are adjacently arranged. The first clamping block 31 is arranged opposite to the first clamping block 31, and the first connecting member 32 is arranged on the turntable 2. The second clamping member 4 includes a second clamping block 41 and a second connecting member 42, and the second connecting member 42 is arranged on the side wall of the second clamping block 41. The two ends of the elastic member 6 are respectively connected to the first connecting member 32 and the second connecting member 42. It can be understood that connecting the two ends of the elastic member 6 to the first connecting member 32 and the second connecting member 42 respectively facilitates the installation of the elastic member 6. Since the first connecting member 32 is arranged adjacent to the first clamping block 31, interference between the elastic member 6 and the workpiece 100 can be avoided during the clamping process of the workpiece 100, thereby improving the applicability of the transfer device.

[0058] Preferably, the first connecting member 32 is provided with a first hooking groove 321, the length of which is arranged along the first direction; the second connecting member 42 is provided with a second hooking groove 421, the length of which is arranged along the second direction, and the first direction is perpendicular to the second direction; the elastic member 6 is a tension spring, and the tension spring is provided with a first hook portion and a second hook portion at each end, respectively, with the first hook portion hooked to the first hooking groove 321, and the second hook portion hooked to the second hooking groove 421. It can be understood that the cooperation between the first groove and the first hook portion, and the cooperation between the second groove and the second hook portion, can prevent the tension spring from detaching from the first connecting member 32 and the second connecting member 42, thereby ensuring safety during the processing. In addition, the first groove and the second groove in different directions can apply forces in different directions to the tension spring, thereby further ensuring the stability of the tension spring during tensioning.

[0059] In this embodiment, a first clamping groove 311 is defined on a side wall of the first clamping block 31 facing the second clamping block 41; a second clamping groove 411 is defined on a side wall of the second clamping block 41 facing the first clamping block 31; and the first clamping groove 311 and the second clamping groove 411 are disposed opposite each other. It will be appreciated that the first clamping block 31 and the second clamping block 41 are capable of clamping both ends of the workpiece 100. The elastic member 6 ensures that the workpiece 100 is always clamped. Furthermore, the first clamping groove 311 and the second clamping groove 411 prevent the workpiece 100 from shifting during transport, thereby ensuring the processing quality of the workpiece 100.

[0060] In addition, the first clamping groove 311 and / or the second clamping groove 411 are configured to conform to the end of the workpiece 100. Since the first clamping groove 311 and the second clamping groove 411 are respectively configured to conform to the corresponding end of the workpiece 100, the workpiece 100 can be further limited in position to ensure the positioning accuracy of the workpiece 100, thereby improving the processing quality of the workpiece 100.

[0061] In this embodiment, the pushing member 5 includes a pushing cylinder 51, a pushing plate 52 and a protrusion 53. The length direction of the piston rod of the pushing cylinder 51 is consistent with the deformation direction of the elastic member 6; the pushing plate 52 is arranged at the end of the piston rod of the pushing cylinder 51; the protrusion 53 is arranged on the second clamping member 4 and is arranged opposite to the pushing plate 52. It can be understood that one of the processing stations is set as the loading and unloading station. Under the action of the pushing cylinder 51, the pushing plate 52 can be pushed close to or away from the loading and unloading station. When any first clamping member 3 and the second clamping member 4 rotate to the loading and unloading station, under the action of the pushing cylinder 51, the pushing plate 52 can push the second clamping block 41 away from the first clamping block 31. At this time, the tension spring is stretched, and the workpiece 100 is placed between the first clamping block 31 and the second clamping block 41. Then, under the action of the pushing cylinder 51, the pushing plate 52 approaches the loading and unloading station. At this time, the pushing plate 52 is disengaged from the second clamping block 41, and the second clamping block 41 can approach the first clamping block 31 under the action of the elastic potential energy of the tension spring to complete the clamping of the workpiece 100.

[0062] Furthermore, the pusher 5 further includes a first abutting portion 54 and a second abutting portion 55. The first abutting portion 54 is detachably disposed on the side of the push plate 52 facing the protrusion 53; the second abutting portion 55 is detachably disposed on the side of the protrusion 53 facing the push plate 52, and the first abutting portion 54 and the second abutting portion 55 are disposed opposite each other. It will be appreciated that the provision of the first abutting portion 54 and the second abutting portion 55 can prevent direct contact between the protrusion 53 and the push plate 52, thereby preventing excessive wear between the protrusion 53 and the push plate 52 after prolonged use, thereby further reducing production costs.

[0063] The first pushing portion 54 and the push plate 52 are connected to each other, and the second pushing portion 55 and the protrusion 53 are connected by bolts. The provision of the bolts facilitates replacement and maintenance of the first pushing portion 54 and the second pushing portion 55, thereby reducing the labor intensity of the workers.

[0064] Furthermore, the pusher 5 also includes a clamp 56 and a mounting plate 57. The clamp 56 is sleeved on the central shaft 1, and the position of the clamp 56 is adjustable. The mounting plate 57 is fixed to the clamp 56 and is used to support the push cylinder 51. It can be understood that by adjusting the direction and height of the clamp 56, the direction and height of the entire pusher 5 can be adjusted, thereby enabling the transfer structure to adapt to different working conditions and further improving the applicability of the transfer structure.

[0065] This embodiment also provides a workpiece processing apparatus for processing a workpiece 100, and having multiple processing stations, including multiple processing devices and a turntable workpiece transfer device. The multiple processing devices are respectively provided at the multiple processing stations, and the multiple processing stations are evenly distributed around the circumference of the turntable 2 of the turntable workpiece transfer device. It will be understood that the provision of the turntable workpiece transfer device can avoid the need for multiple circuits and multiple gas lines, thereby reducing the production cost of the workpiece 100.

[0066] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
