[0034] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0035] Please see Figures 1 to 9 The present invention provides a printing fixture for a rotatable workpiece, comprising a mounting base 1, a material loading assembly 2, a first driving assembly 3, and a pressing assembly 4, wherein the material loading assembly 2 is disposed on the mounting base 1;

[0036] The material loading assembly 2 includes a material trough 201 and a first air passage 202. The first air passage 202 is connected to the material trough 201. The material trough 201 is provided with a notch 2011, which is located on the side wall of the material trough 201. The material trough 201 is used to accommodate external workpieces 100.

[0037] The first driving component 3 is mounted on the mounting base 1 and drives the material loading component 2 to rotate so that the notch 2011 faces upward;

[0038] The pressing component 4 is disposed on the mounting base 1 and located below the loading component 2. The pressing component 4 is used to press the external workpiece 100 into the material groove 201.

[0039] Specifically, in this embodiment, the mounting base 1 includes a base plate 11 and two side plates 12. The two side plates 12 are connected to the base plate 11 in a U-shape. There are several material-carrying components 2 arranged in parallel, with a distance between adjacent material-carrying components 2. Each material-carrying component 2 includes several material slots 201 located between the two side plates 12. Each material slot 201 has a notch 2011. An external workpiece 100 is placed in one material slot 201, with the part of the external workpiece 100 to be printed facing the notch 2011. The first air passage 202 communicates with each material slot 201. When the external workpiece 1... After the workpiece 100 is placed in the material tank 201, external negative pressure gas enters the material tank 201 through the first air passage 202. The external workpiece 100 is attracted and fixed in the material tank 201 by the negative pressure. Then, the first drive component 3 drives the material carrier component 2 to rotate 90°, so that the notch 2011 is set upward. The external printing machine prints on the side surface of the workpiece 100. Preferably, the pressing component 4 is set on the mounting base 1 and located below the material carrier component 2. When the material carrier component 2 rotates 90°, the pressing component 4 rises and presses the external workpiece 100 in the material tank 201, ensuring that the external workpiece 100 is fixed in the material tank 201 during the printing process, and ensuring the stability of the printing quality.

[0040] By installing the material carrier assembly 2, the first drive assembly 3, and the pressing assembly 4 on the mounting base 1, the material carrier assembly 2 is provided with several material slots 201, each material slot 201 is provided with a notch 2011. After the external workpiece 100 is placed in the material slot 201, the part of the workpiece 100 to be printed is exposed through the notch 2011. The first drive assembly 3 drives the material carrier assembly 2 to rotate so that the notch 2011 faces upward, and the external printing machine prints on the side of the workpiece 100. The setting of the pressing assembly 4 ensures that the workpiece 100 is stationary relative to the material slot 201 during the printing process, thereby improving work efficiency and processing quality stability.

[0041] The material loading assembly 2 includes a material rod 21 and a gear shaft 22. The first driving assembly 3 includes a first driving source 31 and a rack 32.

The gear shaft 22 has a second air passage 203, which communicates with the first air passage 202. Several shaft holes are machined in the mounting base 1, and the gear shaft 22 is rotatably connected within these holes. Gear sleeves are fitted at both ends of the gear shaft 22 along its length, meshing with the rack 32. The material rod 21 has a square cross-section. An mounting plane is machined on the shaft of the gear shaft 22 to fix the material rod 21. The material rod 21 and the gear shaft 22 are connected and fixed by screws. Several material grooves 201 are machined along the length of the material rod 21. The radial dimension of 201 is greater than the length of the material rod 21, forming a notch 2011. The notch 2011 is away from the gear shaft 22. The first drive assembly 3 drives the rack 32 to move horizontally, thereby driving the gear shaft 22 to rotate, so that the notch 2011 of the material rod 21 faces upward, which facilitates the printing of the side surface of the workpiece 100 fixed in the material groove 201 by an external printing machine. Preferably, the gear shaft 22 is hollow, and a second air passage 203 is formed by machining a hole in the shaft of the gear shaft 22. External negative pressure gas enters the material groove 201 in sequence through the inner cavity of the gear shaft 22, the second air passage 203, and the first air passage 202, thereby fixing the workpiece 100 in the material groove 201.

[0043] The pressing assembly 4 includes a second drive source 41 and a pressing rod 42. The second drive source 41 is located on the mounting base 1 and drives the pressing rod 42 to rise and fall so that the pressing rod 42 is in contact with the material rod 21. The pressing rod 42 is located close to the material groove 201. Preferably, there are multiple pressing rods 42, with one pressing rod 42 cooperating with one material rod 21. When the material rod 21 rotates 90°, the second drive source 41 drives the pressing rod 42 to rise and fall and contact the surface of the material rod 21, pressing the external workpiece 100 into the material groove 201, ensuring that the workpiece 100 is relatively stationary during the printing process, and improving the stability of production quality.

[0044] The pressing assembly 4 also includes a movable assembly 43. The second driving source 41 drives the movable assembly 43 to rise and fall. The pressing rod 42 is located on the movable assembly 43 and is set away from the mounting base 1. This structure is designed to drive several pressing rods 42 to rise and fall synchronously.

[0045] The movable component 43 includes a lower sliding plate 431, a wedge-shaped member 432, an upper sliding plate 433, and an inclined guide member 434. The lower sliding plate 431 is slidably connected to the mounting base 1. The second drive source 41 drives the lower sliding plate 431 to move. The wedge-shaped member 432 is disposed on the lower sliding plate 431. The upper sliding plate 433 is slidably connected to the wedge-shaped member 432. The inclined guide member 434 is disposed on the mounting base 1. The length direction of the inclined guide member 434 is set at an acute angle to the movement direction of the lower sliding plate 431. The pressure rod 42 is disposed on the upper sliding plate 433. The upper slide plate 433 is positioned away from the lower slide plate 431. Preferably, a slide rail is installed on the mounting base 1, and the lower slide plate 431 slides along the slide rail. There are six wedges 432, with three wedges 432 in a row. When the second drive source 41 drives the lower slide plate 431 to move, the wedges 432 move synchronously. The wedges 432 push the upper slide plate 433 to move upward. Under the restriction of the inclined guide 434, the upper slide plate 433 moves obliquely upward, that is, the pressure rod 42 gradually approaches the side surface of the material rod 21 and presses against the side surface, achieving the purpose of gradually approaching.

[0046] The active component 43 also includes guide wheels 435. The upper slide plate 433 is provided with a through hole. The guide wheels 435 are housed in the through hole and are rotatably connected to the upper slide plate 433. The guide wheels 435 are slidably connected to the wedge-shaped member 432. There are six guide wheels 435. One guide wheel 435 cooperates with one wedge-shaped member 432. The guide wheels 435 and the wedge-shaped member 432 are in line contact, which reduces frictional resistance and reduces the output energy consumption of the second drive source 41.
