The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0025] Example 1: As Figures 1-4 The assembly includes a tooling table 100, with a through groove 130 at the center of its inner wall. The inner wall of the through groove 130 is rotatably connected to a turntable 200 via a pivot 240. The top of the turntable 200 is evenly provided with screw holes 210, and there are several screw holes 210. The inner wall of the screw holes 210 is threadedly connected to a movable clamp. The movable clamp includes a base plate 300, with a screw rod 310 fixedly connected to the bottom of the base plate 300 and a guide rail compartment 320 fixedly installed on the top of the base plate 300. The inner wall of the guide rail compartment 320 is slidably connected to a clamping seat 360, which is used to position the wheelchair frame on the top of the tooling table 100.
[0026] The specific application scenario of this embodiment is as follows: By rotating and connecting the turntable to the inner wall of the tooling table 100, and controlling the rotation of the turntable 200 by setting a stepper motor 250, the turntable 200 is locked. This allows for flexible adjustment of the turntable angle during the assembly of the wheelchair frame according to operational needs. By setting a movable clamp, which is detachably connected to the top of the turntable 200, it is convenient to position the top of different models of wheelchair frames, making it easy to adapt to different models of wheelchair frames and convenient for multi-functional and flexible use.
[0027] Example 2: As Figure 6 The bottom outer wall of the tooling table 100 is fixedly mounted with support legs 110, and the top of the left and right sides of the tooling table 100 is fixedly mounted with platform 120. The rear outer wall of the tooling table 100 is provided with a motor mounting groove 101. The outer wall of the rotating shaft 240 is fixedly mounted with a pointer 241, and the outer wall of the tooling table 100 is fixedly mounted with an angle plate 140. The pointer 241 and the angle plate 140 are used to indicate the rotation angle of the turntable 200. The bottom of the turntable 200 is rotatably connected to the rotating shaft 240 through a locking bracket 220 and a semi-circular groove at the bottom of the turntable 200. The rotating shaft 240 is rotatably connected to the inner wall of the motor mounting groove 101. The inner wall of the motor mounting groove 101 is fixedly mounted with a stepper motor 250. The outer wall of the output shaft of the stepper motor 250 is connected to the outer wall of the rotating shaft 240 through a first bevel gear 251. The front outer wall of the motor mounting groove 101 is fixedly mounted with a protective cover 150. The inner wall of the protective cover 150 is evenly provided with heat dissipation holes 151.
[0028] The specific application scenario of this embodiment is as follows: by turning on the stepper motor 250, the stepper motor 250 can drive the rotating shaft 240 to rotate, so that the rotating shaft 240 can drive the turntable 200 to rotate and adjust the angle. By using the pointer 241 and the angle dial 140 together, the turntable 200 can be freely adjusted to change its flip angle, so that the operator can easily flip the angle of the wheelchair frame.
[0029] Example 3: As Figures 3-5 A first handwheel 330 for adjusting the rotation of the guide rail compartment 320 is fixedly installed on the top outer wall of the guide rail compartment 320. The top and bottom inner walls of the guide rail compartment 320 are rotatably connected to the lead screw 340 through bearings. The outer wall of the lead screw 340 is threadedly connected to the inner wall of the clamp 360. The top inner wall of the guide rail compartment 320 is rotatably connected to the drive shaft 350 through the bearing seat 351 and the side wall of the guide rail compartment 320. The outer wall of the drive shaft 350 is meshed with the outer wall of the lead screw 340 through a second bevel gear 352. A second handwheel 353 is fixedly installed on the end outer wall of the drive shaft 350. The clamp 360 is L-shaped. The clamping surface of the clamp 360 is detachably fixedly installed with a clamping plate 361. A flexible rubber anti-slip pad 362 is fixedly installed on the outer wall of the clamping plate 361.
[0030] The specific application scenario of this embodiment is as follows: by rotating the second handwheel 353, the second handwheel 353 drives the drive shaft 350 to rotate, which in turn drives the lead screw 340 to rotate. The lead screw 340 then drives the clamp 360 to adjust its height, thereby allowing the clamp 360 to press against the top of the wheelchair frame and fix the wheelchair frame to the top of the platform 120. This facilitates stable clamping and positioning of different models of wheelchair frames.
[0031] The working principle of this utility model is as follows: When used by those skilled in the art, the wheelchair frame is placed on the platform 120 at the top of the tooling table 100, and then the wheelchair frame is assembled on the top of the turntable 200. The movable clamp is selectively installed on the screw hole 210 at the corresponding position on the top of the turntable 200 according to the position of the wheelchair frame. After the movable clamp is installed on the top of the turntable 200, the second handwheel 353 is rotated by hand, which drives the drive shaft 350 to rotate, so that the drive shaft 350 drives the lead screw 340 to rotate, so that the lead screw 340 drives the clamp seat 360 to adjust the height. The height of the seat 360 allows the clamp 360 to press against the top of the wheelchair frame, thus fixing the wheelchair frame to the top of the platform 120. When it is necessary to adjust the angle of the turntable 200, the stepper motor 250 is turned on, which drives the rotating shaft 240 to rotate, thereby rotating the turntable 200 to adjust the angle. The pointer 241 and the angle dial 140 work together to facilitate the free adjustment of the rotation angle of the turntable 200, making it convenient for the operator to rotate the wheelchair frame and improving the practicality of the equipment.
[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
