[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The preferred embodiment of the present invention is a twisting processing device, such as... Figure 1-5 As shown, this device includes a base 10, a movable seat 20, and a positioning seat 30 arranged sequentially from bottom to top, wherein the base 10 is elongated. The device also includes a rotating mechanism 40 for driving the positioning seat 30 to rotate, and a lifting mechanism 50 for driving the rotating mechanism 40 to move up and down. The movable seat 20 and the positioning seat 30 are connected by a connecting assembly 60; each of the opposite sidewalls of the movable seat 20 and the positioning seat 30 has a mounting groove 70; the two mounting grooves 70 enclose to form a mounting cavity 80; multiple movable blocks 90 are arranged horizontally circumferentially within the mounting cavity 80, and the multiple movable blocks 90 horizontally enclose to form a circular structure. The lower part of the adjacent ends of the multiple movable blocks 90 is provided with an inclined surface 91 penetrating their bottom surface, and the multiple inclined surfaces 91 horizontally enclose to form an upper positioning groove 100 for positioning the workpiece. A window 110 for the upper half-shell workpiece to pass through is provided on the bottom surface of the mounting cavity 80, and a lower positioning groove 120 is provided on the base 10 corresponding to the upper positioning groove 100, specifically in a hemispherical shape. Furthermore, anti-slip pads 130 are provided on the inner walls of the upper positioning groove 100 and the lower positioning groove 120 to prevent the workpiece from slipping, and layered components that increase friction are provided on the upper and lower inner walls of the mounting cavity 80 to prevent the movable block 90 from slipping during the screwing operation.

[0028] During operation, the worker aligns and screws the two hemispherical workpieces together before placing them into the lower positioning groove 120 on the base 10. Then, the lifting mechanism 50 is activated to drive the rotating mechanism 40, the positioning seat 30, and the movable seat 20 to descend synchronously, so that the upper part of the workpiece passes through the window 110 and enters the upper positioning groove 100. After it is in place, the upper part of the workpiece abuts against the movable block 90, which then presses the movable block 90 upward against the inner fixed wall and side wall of the mounting cavity 80. Then, the rotating mechanism 40 is activated and drives the positioning seat 30 and the movable seat 20 to rotate horizontally relative to the base 10, thereby tightening the two hemispherical workpieces.

[0029] Compared to traditional manual assembly methods, this device can achieve higher precision and faster assembly and tightening of the two hemispherical shells. Moreover, the overall structure is simple and easy to operate, which greatly improves processing efficiency and reduces the labor intensity of workers.

[0030] In this embodiment, two adjacent movable blocks 90 in the circumferential direction are connected to each other by an elastic connector 140, which enables multiple movable blocks 90 to automatically retract and reset towards the center. The elastic connector 140 can be a spring, a tension spring, a torsion spring, or an elastic metal sheet, and can be rotated in different ways according to actual needs. In this solution, a tension spring is preferred.

[0031] In this embodiment, the upper positioning groove 100 is a cone shape that is narrow at the top and wide at the bottom, and the window 110 is circular. When assembled, the edge of the window 110 is aligned with the lower edge of the upper positioning groove 100. The cone-shaped upper positioning groove 100 can accommodate workpieces of different diameters, reducing the frequency of parts replacement for the equipment.

[0032] In this embodiment, both the positioning seat 30 and the movable seat 20 are cylindrical and coaxial with each other. Multiple connecting components 60 are provided and are evenly distributed circumferentially on the outer circumferential sidewall of the positioning seat 30. Multiple movable blocks 90 correspond one-to-one with multiple connecting components 60. Specifically, there are four movable blocks 90 and four connecting components 60. The four movable blocks 90 are divided into four equal parts and enclose a frustum-shaped structure. The included angle between the two sidewalls in the circumferential direction of each movable block 90 is a right angle. Specifically, the connecting assembly 60 includes two horizontally opposite and parallel side plates 61 arranged on the outer peripheral sidewall of the positioning seat 30, a horizontally arranged U-shaped member 62, and a vertically arranged hanging ring 63; the two arms of the U-shaped member 62 are horizontally opposite and fixed to the outer peripheral sidewall of the movable seat 20; the upper end of the hanging ring 63 is located between the two side plates 61 and the lower end is located between the two arms of the U-shaped member 62 and abuts against the inner sidewall of the connecting part of the two arms of the U-shaped member 62; the two side plates 61 are connected by horizontal upper pins 150, and the two arms of the U-shaped member 62 are connected by horizontal lower pins 160. The upper pins 150 and the lower pins 160 are parallel to each other and both penetrate the inner cavity 631 of the hanging ring 63. The inner cavity 631 of the hanging ring 63 is elongated and longitudinally arranged, and its length is greater than the sum of the diameters of the upper pins 150 and the lower pins 160. The two side plates 61 and the two arms of the U-shaped piece 62 are attached to the hanging ring 63 to achieve longitudinal hinge with the hanging ring 63, so that the movable seat 20 can move downward relative to the positioning seat 30 when not in operation.

[0033] When the positioning seat 30 is pressed down, both the upper and lower ends of the movable block 90 abut against the upper and lower inner walls of the positioning groove, and achieve relative positioning through the friction of the layered components; while after the positioning seat 30 moves up, the movable seat 20 is hung on the upper pin under the connecting and limiting action of the hanging ring 63. The hanging ring 63 has an upward-facing first inclined surface 632 on one side wall facing the positioning seat 30. Both the positioning seat 30 and the movable seat 20 have clearance notches 170 on their side walls to avoid the first inclined surface 632. When assembled, the lower outer side wall of the hanging ring 63 abuts against the bottom surface of the clearance notch 170 on the movable seat 20, and the lower pin secures the hanging ring 63 to the bottom surface of the clearance notch 170 on the lower side, thereby achieving relative fixation between the hanging ring 63 and the movable seat 20. When the positioning seat 30 is pressed down, the upper end of the hanging ring 63 abuts against the bottom surface of the clearance notch 170 on the upper side. At the same time, the bottom surface of the positioning seat 30 presses the movable block 90 against the bottom surface of the mounting frame, thereby achieving downward pressing of the upper shell workpiece against the lower shell workpiece. Furthermore, a second inclined surface 92 is provided on the side wall of the movable block 90 near the first inclined surface 632, facing downwards. When assembled, the lower end of the back of the hanging ring 63 abuts against the connection between the two arms of the U-shaped piece 62, and the second inclined surface 92 is attached to the first inclined surface 632. Thus, multiple movable blocks 90 are supported by multiple first inclined surfaces 632 facing upwards. This allows the movable block 90 to return to its original position a certain distance upwards after the positioning seat 30 and the movable seat 20 are separated, thus preventing the movable block 90 from getting stuck.

[0034] In this embodiment, the second inclined surface 92 is an arc-shaped surface, and multiple second inclined surfaces 92 enclose a frustum shape that is narrow at the bottom and wide at the top, so as to ensure that multiple movable blocks 90 can move smoothly and horizontally in the mounting cavity 80 at the same time. Of course, during the movement of the movable block 90, the upper positioning groove 100 can still be aligned with the window 110 so that the upper shell workpiece can enter the upper positioning groove 100 normally.

[0035] In this embodiment, a mounting bracket 180 is provided on the movable terminal of the lifting mechanism 50, and a rotating mechanism 40 is provided on the mounting bracket 180. A vertical rotating shaft 190 is provided at the lower end of the mounting bracket 180, and the rotating shaft 190 is rotatably connected to the mounting bracket 180. The positioning seat 30 is located below the mounting bracket 180 and is coaxially fixedly connected to the rotating shaft 190. Specifically, the mounting bracket 180 includes two parallel mounting plates 181, which are fixedly connected by multiple connecting shafts 200 in the middle. The length of the upper mounting plate 181 is greater than that of the lower mounting plate 181, and the rotating mechanism 40 is provided on the upper surface of the upper mounting plate 181.

[0036] In this embodiment, the device further includes a mounting base 210 and a fixing frame 220 disposed on the upper surface of the mounting base 210; the base 10 is disposed on the upper surface of the mounting base 210, and the lifting mechanism is disposed on the fixing frame 220. Specifically, the lifting mechanism 50 is a cylinder, with the cylinder's movable terminal passing through the fixing frame 220 downwards and fixedly connected to the mounting frame 180. The further rotating mechanism 40 includes a motor 41 vertically disposed on the mounting frame 180, a first pulley 42 disposed on the rotating shaft of the motor 41, a second pulley 43 coaxially fixed on the rotating shaft 190, and a transmission belt 44 drivingly connecting the first pulley 42 and the second pulley 43; wherein, the first pulley 42 and the second pulley 43 are both located in the middle of the two mounting plates 181, the motor 41 is vertically disposed on the upper mounting plate 181, and the belt is disposed between the two mounting plates 181 to provide protection.
