However, the outer surface of the sole is usually sprayed with paint by a manual handheld spray gun. The manual spraying method is time-consuming and labor-intensive, and the spraying efficiency is low, and the uniformity of the spraying is difficult to ensure, which in turn affects the production efficiency of the sole and the appearance quality of the sole. Therefore, it is extremely important to use an intelligent manipulator to drive a spray gun for automatic spraying. In order to ensure the smooth progress of the automatic spraying, a corresponding clamp is required to clamp the sole. How to propose a sole spraying clamp that can stably clamp the sole during the automatic spraying process and ensure the spraying effect and is convenient and easy to take and put the sole is the technical problem to be solved by the present application.

DETAILED DESCRIPTION

[0022] The present invention is further described below through specific implementation methods.

[0023] like Figures 1 to 6 As shown, the shoe sole spray painting fixture described in the utility model comprises a rotating seat 1, an intermittent rotating driving mechanism 2, a bottom clamping seat 3 and a top pressing cover 4.

[0024] The rotating seat 1 is rotatably installed on the rotating frame 5, the intermittent rotation driving mechanism 2 is arranged on the rotating frame 5 and is used to drive the rotating seat 1 to rotate intermittently, the bottom clamp seat 3 is connected to the upper end of the rotating seat 1, the bottom clamp seat 3 is used to place the detachable sole 6 and shield the bottom surface of the sole 6, effectively preventing the paint from being sprayed onto the bottom surface of the sole 6 during the painting process, the top pressure cover 4 is detachably arranged on the top surface of the sole 6 and is used to press the sole 6 by its own weight and can shield the top surface of the sole 6, the top pressure cover 4 can be conveniently removed to facilitate the easy placement and removal of the sole 6, and effectively prevent the paint from being sprayed onto the bottom surface of the sole 6 during the painting process. The top surface of the sole 6, thereby only the outer peripheral surface of the sole 6 that needs to be painted is completely exposed to better ensure the painting effect, the top surface of the bottom clamp seat 3 is provided with an interlocking groove 31 adapted to the bottom of the sole 6 to ensure that the sole 6 is stably placed in the bottom clamp seat 3, the bottom surface of the top pressure cover 4 is fixedly provided with an interlocking block 41 adapted to the groove 61 on the top surface of the sole 6, and the top pressure cover 4 itself has a certain weight to ensure that the top pressure cover 4 is stably covered on the top surface of the sole 6, further ensuring that the top pressure cover 4 will not be separated from the sole 6 during the painting and rotation process, thereby achieving stable clamping of the sole 6 during the automatic painting process.

[0025] In addition, a rotating shaft 71 is fixedly provided at the center of the bottom end surface of the rotating seat 1, and a rotating hole is provided on the rotating frame 5. The rotating shaft 71 is rotatably installed in the rotating hole of the rotating frame 5 through a bearing 72, thereby facilitating the rotational connection between the rotating seat 1 and the rotating frame 5.

[0026] The intermittent rotation drive mechanism 2 is used to drive the rotating seat 1 to intermittently rotate 120 degrees each time. The intermittent rotation drive mechanism 2 includes a servo motor 21, a motor seat 22 and a coupling 23. The servo motor 21 is fixedly mounted on the motor seat 22, and the motor seat 22 is fixedly mounted on the bottom end surface of the rotating frame 5. The lower end of the rotating shaft 71 extends downward and passes through the bottom surface of the rotating frame 5. The motor shaft of the servo motor 21 is transmission-connected to the lower end of the rotating shaft 71 through the coupling 23. By controlling the servo motor 21 to rotate 120 degrees each time, the rotating seat 1 can be driven to perform an intermittent rotation of 120 degrees, so that the sole 6 follows the rotation of 120 degrees. In this way, during the entire painting process of the sole 6, the sole 6 needs to be rotated 3 times to achieve the painting of the entire peripheral surface of the sole 6.

[0027] The rotating seat 1 includes a U-shaped bottom frame 11 , and a connecting plate 12 is fixedly disposed at an open end of the U-shaped bottom frame 11 .

[0028] The bottom clamp seat 3 is detachably connected to the rotating seat 1 through a locking mechanism 8, thereby facilitating the replacement of the bottom clamp seat 3, and the top pressure cover 4 is replaced together, and replaced with a structure of different style or size to adapt to the painting operation of the soles 6 of different styles or sizes. The locking mechanism 8 includes a locking stud 81 and a locking nut 82. At least one locking stud 81 is fixedly provided on the bottom end surface of the bottom clamp seat 3. The connecting plate 12 is provided with at least one locking hole 121 matched with the locking stud 81. The lower end of the locking stud 81 passes through the locking hole 121 and is threadedly connected to the locking nut 82. The disassembly and assembly is simple and convenient, and when locked and fixed, the stability of the installation position of the bottom clamp seat 3 can be effectively ensured. Preferably, the number of the locking stud 81 and the locking hole 121 are both two and are arranged in one-to-one correspondence.

[0029] In addition, two symmetrical gripping grooves 42 are provided on the outer circumferential surface of the pressing cover 4 to facilitate gripping and lifting of the pressing cover 4, thereby effectively preventing the pressing cover 4 from accidentally slipping and falling when being taken.

[0030] The outer contours of the bottom clamp seat 3 and the top pressure cover 4 are adapted to the outer contour of the sole 6 .

[0031] The bottom surface of the bottom clamp seat 3 is flat to facilitate the installation of the bottom clamp seat 3, and the depth of the fitting groove 31 is 2-4 mm. Therefore, while ensuring that the sole 6 can be stably placed in the fitting groove 31, the area of ​​the outer peripheral surface of the sole 6 can be exposed to the maximum extent.

[0032] The above are only some specific implementation methods of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
