[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 , a pallet for placing a headstock during the assembly of a lathe, including a pallet body 1. Guide wheels are installed at the bottom of the pallet body 1. The guide wheels can be installed on the pallet body 1 through bolts, and the pallet body 1 can slide and displace on the guide rail through the guide wheels.

[0024] In this embodiment, please refer to Figure 2 , Figure 3 and Figure 4 , two first slide plates 2 are installed on the upper side of the pallet body 1. Positioning frames 4 are respectively installed on the inner sides of the opposite ends of the two first slide plates 2. The outer sides of the wider ends of the headstock base can be positioned through the positioning frames 4. The lower ends of the first slide plates 2 are slidably connected to the inside of the pallet body 1, and a first lead screw 7 is threadedly connected to the inside of the lower end of each first slide plate 2. The first lead screw 7 is rotatably connected to the inside of the pallet body 1. By rotating the first lead screw 7, the first slide plate 2 can be driven to translate.

[0025] Specifically, a first bevel gear 5 is rotatably connected to the inside of the pallet body 1. The first bevel gear 5 is driven by a motor. The motor is installed at the bottom of the pallet body 1, and the output shaft of the motor is connected to the first bevel gear 5. The specific connection method can adopt the existing technology. Four second bevel gears 6 are meshed and connected to the outside of the first bevel gear 5. The four second bevel gears 6 are arranged at equal angles. By rotating the first bevel gear 5, the four second bevel gears 6 can be driven to rotate simultaneously.

[0026] Each first lead screw 7 is fixed to a second bevel gear 6, so that the rotation of the first bevel gear 5 and the second bevel gear 6 can drive the two first lead screws 7 to rotate simultaneously. At the same time, the thread directions of the two first lead screws 7 are the same. Furthermore, the two first lead screws 7 drive the two first slide plates 2 to translate in opposite directions through rotation, and the two positioning frames 4 approach or move away from each other.

[0027] A sliding block 41 is slidably connected to the inside of the upper end of the first slide plate 2, and a third lead screw 9 is threadedly connected to the inside of the sliding block 41. By rotating the third lead screw 9, the sliding block 41 can be driven to move. Moreover, two hydraulic rods 42 are installed inside the lower end of the sliding block 41, and the output ends of the hydraulic rods 42 are connected to the positioning frame 4. By adjusting the telescopic movement of the hydraulic rods 42, the lifting of the positioning frame 4 can be adjusted, facilitating the positioning frame 4 to adapt to the position of the spindle box base.

[0028] Furthermore, convex blocks 411 are respectively fixed at both ends of the sliding block 41, enabling the sliding block 41 to perform limited sliding inside the upper end of the first slide plate 2 through the convex blocks 411. The convex blocks 411 provide a supporting effect on the sliding block 41 to reduce the supporting load of the third lead screw 9 on the sliding block 41.

[0029] In a further embodiment, please refer to Figure 1 and Figure 2 , two second slide plates 3 are further provided on the upper side of the pallet body 1. The two ends of the spindle box base that are relatively narrow can be positioned through the second slide plates 3. The lower ends of the second slide plates 3 are slidably connected to the inside of the pallet body 1. A second lead screw 8 is threadedly connected to the inside of the lower end of each second slide plate 3, and each second lead screw 8 is fixed to a second bevel gear 6. Due to the meshing connection between the first bevel gear 5 and the second bevel gear 6, when the first bevel gear 5 rotates, it can drive the second lead screw 8 to rotate through the transmission of the second bevel gear 6, thereby enabling the two second lead screws 8 to rotate simultaneously, and further enabling the two second lead screws 8 to translate simultaneously.

[0030] Furthermore, the thread directions of the two second lead screws 8 are the same, such that when the two second lead screws 8 rotate simultaneously, the translation directions of the two anti-slip pads 31 are opposite. When translating, the two second slide plates 3 approach or move away from each other, and anti-slip pads 31 are respectively adhered to the opposite sides of the two second slide plates 3. By contacting the anti-slip pads 31 with the spindle box base, the friction force when the second slide plates 3 clamp and position the spindle box base is increased.

[0031] During the assembly of the lathe, the bottom of the pallet body 1 is slidably connected to the guide rail through the installation of guide wheels. After the assembly of the pallet body 1 and the guide rail is completed, the spindle box is installed on the pallet body 1. The spindle box contacts the pallet body 1 through its base, and the two relatively narrow ends of the spindle box correspond to the two relatively narrow ends of the pallet body 1. Then, the first bevel gear 5 is driven to rotate by a motor. At this time, the four second bevel gears 6 rotate simultaneously, thereby enabling the two first lead screws 7 and the two second lead screws 8 to rotate simultaneously. At this time, the two second slide plates 3 approach. After the anti-slip pads 31 are in close contact with the base of the spindle box, the two second slide plates 3 clamp and position the two relatively narrow ends of the spindle box base.

[0032] When the bases of the two second slide plates 3 close to the headstock are translated, the two first slide plates 2 approach each other simultaneously. After the two second slide plates 3 clamp the headstock base, if the positioning frame 4 does not contact the headstock base, the third lead screw 9 is rotated at this time, so that the positioning frame 4 moves in the direction close to the headstock base. After the positioning frame 4 approaches the headstock base, the hydraulic rod 42 is activated to drive the positioning frame 4 to descend, so that after the positioning frame 4 contacts the headstock base and positions it. Through the position movement of the second slide plate 3 and the positioning frame 4, it is convenient to position and install the headstock bases of different specifications and sizes, improving the adaptability of the placement pallet.
