Those skilled in the art can reasonably determine the specific meaning of the above words in the present application after combining with the specific content of the technical solution.

[0037] Refer to Figures 1 to 3 , the lens locking fixture according to the embodiment of the first aspect of the present application is a fixture for compatibly locking multiple-caliber lenses with controllable torque. The lens locking fixture includes a driving component 100 and a lens mounting component 200.

[0038] The lens mounting component 200 includes an adjusting member 210, a tightening member 220, and a driven shaft 230. The output end of the driving component 100 is connected to one end of the driven shaft 230. The other relative end of the driven shaft 230 is provided with a mounting position 231 for placing the lens. Each tightening member 220 is movably arranged at intervals in the circumferential direction of the mounting position 231. The adjusting member 210 is used to synchronously drive the tightening member 220 to move radially, so that when each tightening member 220 limits the lens, the driving component 100 can apply torque to the lens through the driven shaft 230. It can be understood that the mounting position 231 of the driven shaft 230 accommodates a group of lenses or retaining rings of different sizes, and the adjusting member 210 is used to synchronously drive the tightening member 220 to move radially for adjustment, so as to be able to clamp lenses with different outer diameters, and finally realize locking by providing torque through the driving component 100, so as to solve the problem of fixture compatibility as much as possible.

[0039] In some embodiments, the driving component 100 can output a specific value of torque. Since the lens is reliably set on the mounting position 231 of the driven shaft 230 through the tightening member 220, the driving component 100 can apply the required tightening torque to the lens through the transmission of the driven shaft 230. When in use, a technician holds the lens or fixes the lens through a mechanism or device, and at the same time applies torque to the driving shaft using the driving component 100 with the set torque. It should be noted that the mounting position 231 is designed as a blind hole capable of accommodating a lens with a larger size. By adjusting the radial position of the tightening member 220 at the other end of the driven shaft 230, the clamping of lenses with different sizes can be adapted, thereby improving the adaptability of the jig.

[0040] In some embodiments of the present application, a plurality of radially extending slots 232 are provided around the mounting position 231 on the opposite end of the driven shaft 230. A plurality of inclined slots 211 are spaced apart on the adjusting member 210. The adjusting member 210 is disposed adjacent to the opposite end of the driven shaft 230. Each tightening member 220 is slidably disposed on each slot 232 and is limited by the inclined slot 211, so that when the adjusting member 210 rotates, it can drive each tightening member 220 to slide on the guiding slot. In some embodiments of the present application, the lens mounting component 200 further includes a plug pin 250. A corresponding pin hole is provided on the adjusting member 210. The plug pin 250 is used to insert into the pin hole to fix the position of the adjusting member 210 after the rotation adjustment of the adjusting member 210 is completed. It can be understood that the plug pin 250 is cylindrical and cooperates with the adjusting member 210 to play a fixing role. When rotating the adjusting member 210, the plug pin 250 needs to be pulled out. After rotating to a suitable position, the plug pin 250 is inserted to fix the position of the adjusting member 210. Based on the setting of the inclined slot 211, the adjusting member 210 can drive each tightening member 220 to slide along the slot 232 by rotation. It should be noted that the lower end of the driven shaft 230 is used to receive torque, and the upper end is used to mount the lens. The adjusting block of the adjusting member 210 is disc-shaped, and there is a through hole in the center for the driven shaft 230 to pass through. The through hole cooperates with the upper end portion of the driven shaft 230 to adjust and adapt to lenses with different outer diameters. Four inclined slots 211 and a straight slot are milled on the end face. The inclined slots 211 are used as slide rails to adjust the distance between the tightening members 220 to adapt to lenses with different outer diameters, and the straight slot is used to fix the adjusting block through the plug pin 250 after adjusting the position of the tightening block.

[0041] In some embodiments, for the convenience of adjustment, the structure, size, and position of the straight slot and the jack on the upper end of the driven shaft 230 that cooperate with the plug pin 250 can be adjusted and designed adaptively to adapt to lenses with different size specifications. In some embodiments, the tightening member 220 is a tightening block, which is convenient for processing and forming and is convenient for slidingly disposed on the slot 232.

[0042] In some embodiments of the present application, a first protrusion 221 is provided at one end of the tightening member 220 relatively close to the mounting position 231. The first protrusion 221 is adapted to be matched with the bayonet 300 of the lens. A sliding portion 223 is provided on a side surface of the tightening member 220 relatively close to the adjusting member 210. The sliding portion 223 is slidably disposed on the inclined groove 211. In some embodiments of the present application, the adjusting member 210 is sleeved on the bottom surface of the opposite end of the driven shaft 230. A plurality of pressing pieces 240 for pressing the respective tightening members 220 are provided on the top surface of the opposite end of the driven shaft 230. In some embodiments of the present application, a second protrusion 222 is provided at a preset position at the top end of the tightening member 220, so that the pressing piece 240 can limit the tightening member 220 at a preset radial position by abutting against the second protrusion 222. It can be understood that the tightening member 220 is assembled on the bayonet 300 of the driven shaft 230 and fixed by screwing the pressing piece 240 to the driven shaft 230. It should be noted that the tightening member 220 is a screwing block, the main body is a cuboid, a cylinder similar to a pin is processed at the bottom, and a small boss is processed on both the end face and the side face. The boss on the end face is used to limit the distance between the screwing blocks when adapting to lenses of different outer diameters, and the boss on the side face is used to cooperate with the bayonet 300 of the lens to apply the required torque to the lens. The cylinder processed at the bottom cooperates with the inclined groove 211 of the adjustment block, and then by rotating the adjustment block, the mutual movement between the cylinder and the inclined groove 211 acts on the front and back sliding of the screwing block, so as to complete the function that the jig can be adapted to lenses of different outer diameters.

[0043] In some embodiments, the pressing piece 240 is similar to a small iron sheet, with two through holes processed, attached to the end face of the driven shaft 230, contacting the end face of the screwing block to prevent the screwing block from falling off, and at the same time, it can also cooperate with the second protrusion 222 to play a role in limiting.

[0044] In some embodiments, the driven shaft 230 is divided into three parts. The upper end is processed with 8 threaded holes and 1 through hole. The threaded holes are used to assemble the pressing piece 240 to fix the screwing block, and the through hole is used to fix the position of the guide rail on the adjustment block through the pin 250 after adjusting the position of the screwing block. A blind hole is processed in the center to place the lens component that needs to be tightened with torque. Four through holes are processed on the side wall of the blind hole as exhaust holes to achieve the function of exhausting the placed parts. Four horizontal grooves are processed on the upper end plane to place the screwing blocks and provide an adjustable space. A fixing groove is also reserved at the upper end. After installing the adjustment block, a circlip is used and placed in the fixing groove to fix the adjustment block. The stepped shafts at both ends of the middle part are used to assemble thrust bearings and deep groove ball bearings to bear axial force and radial force. A keyway is milled at the lower end to cooperate with the gear to receive the transmission of torque.

[0045] In some embodiments of the present application, the driving component 100 includes an input shaft assembly 110, a transmission gear assembly 120, and a driven gear assembly 130. The input shaft assembly 110 is connected to the transmission gear assembly 120, the driven gear assembly 130 is connected to the driven shaft 230, and the transmission gear assembly 120 and the driven gear assembly 130 are meshed. It can be understood that the input shaft assembly 110 includes a bit head and a transmission shaft. The transmission gear assembly 120 includes a gear, a snap ring, a bushing, a thrust bearing, and a deep groove ball bearing. One end of the transmission shaft is connected to the bit head by a screw, and a set retaining ring torque is applied through the bit head. The other end of the transmission shaft is assembled with the gear by a key, and the power is transmitted to the driven gear assembly 130 through the gear, and the driven gear assembly 130 drives the transmission shaft to rotate. The deep groove ball bearing bears the radial force of the transmission shaft when applying torque, and the reliable connection between the transmission shaft and the thrust bearing and the deep groove ball bearing is achieved through the snap ring and the bushing.

[0046] Further, the driven gear assembly 130 includes a driven gear, two snap rings, a thrust bearing, a bearing, a bushing, and a key. After one end of the driven shaft 230 is assembled with the gear by a key, it is connected to the gear on the transmission shaft to achieve the transmission effect. The adjusting member 210 is connected to the other end of the driven shaft 230 by being limited by one of the snap rings. The thrust bearing bears the axial force of the driven shaft 230 when applying torque, and the deep groove ball bearing bears the radial force of the driven shaft 230 when applying torque. The assembly position of the gear is fixed through the other snap ring and the bushing.

[0047] In some embodiments, the bushing is tubular, which serves to position the gear and fix the bearing. The ways of arranging the snap ring, the bushing, the thrust bearing, and the deep groove ball bearing on the shaft are conventional means, so no further description will be given.

[0048] In some embodiments, the upper part of the bit head is prismatic, and an arc-shaped bayonet 300 is machined on the prism for connecting a torque wrench. The torque value applied can be precisely controlled through the torque wrench. The lower part is flat cylindrical, and four through holes are opened on it, and it is connected to the transmission shaft by screws and becomes a part of the driving component 100.

[0049] In some embodiments of the present application, the lens locking fixture further includes a mounting plate 400, a support plate 500, and support columns 600. A plurality of support columns 600 are provided and spaced on the mounting plate 400. The support columns 600 are used to support the support plate 500. The transmission gear assembly 120 and the driven gear assembly 130 are arranged between the mounting plate 400 and the support plate 500, and the lens mounting component 200 and the driving component 100 are arranged on the support plate 500. It can be understood that the mounting plate 400 serves as a bearing foundation, and the support columns 600 are vertically arranged on the mounting plate 400 at intervals to define a placement space for the gears, and the support plate 500 is arranged on the support columns 600, and each component is mounted on the support plate 500, and the overall structural design is reasonable.

[0050] In some embodiments of the present application, pull up the installed jig pin 250, rotate the adjusting member 210 to rotate the tightening member 220 to the maximum distance, place the pre-tightened lens mount 300 downward in the blind hole machined on the driven shaft 230, and then through the rotating adjusting member 210, rotate the inclined groove 211 of the adjusting member 210 to drive the movement of the small cylinder at the bottom of the tightening member 220, so that the tightening member 220 moves back and forth in the card slot 232 of the driven shaft 230, thereby adjusting the small boss on the side of the screwing block to a position matching the lens mount 300, avoiding the small boss on the side of the screwing block being too loose or too tight with the lens mount 300 of the lens. Being too loose will cause slipping when applying torque, and being too tight will cause wear on the opening of the lens during the torque application process, resulting in poor appearance. After adjustment, insert the pin 250 to fix the position of the adjusting member 210 and prevent its actuation from driving the position of the tightening member 220. Subsequently, hold the lens with one hand and use a manual screwdriver with a set torque to apply torque to the transmission shaft with the other hand. The driving shaft rotates and transmits the torque to the driven shaft 230 through a gear transmission ratio of 1:1, causing the tightening member 220 installed on the driven shaft 230 to rotate and apply the required tightening torque to the lens.

[0051] Refer to Figures 1 to 3 , the lens locking device according to the second aspect embodiment of the present application includes the lens locking jig according to the first aspect embodiment of the present application. Using a control jig compatible with multiple-caliber lenses can improve the compatibility and production efficiency of the device.
