DETAILED DESCRIPTION

[0023] As shown in the accompanying drawings, the present embodiment provides a device for lifting and translating the lower cover of a vacuum furnace, comprising a stand 1, the stand 1 being horizontally provided with a support track 2, a moving trolley 3 being movably provided on the support track 2, and a lower cover 4 being fixed above the moving trolley 3. The lower cover 4 is driven to move simultaneously by the movement of the moving trolley 3, and the moving trolley 3 is still connected to the lower cover 4 after the lower cover 4 is installed below the vacuum furnace cavity 15.

[0024] A horizontal lead screw 5 is arranged on the platform 1 parallel to the supporting rail 2, and a horizontal movement control motor 6 is arranged in conjunction with the horizontal lead screw 5 for driving the horizontal lead screw 5 to rotate. The horizontal movement control motor 6 is an adjustable speed motor for realizing horizontal movement speed regulation. A horizontal nut slider 7 is arranged in conjunction with the horizontal lead screw 5, and the moving trolley 3 is detachably connected to the horizontal nut slider 7.

[0025] The horizontal nut slider 7 is U-shaped, and a positioning plate 11 is vertically arranged at the position of the mobile trolley 3 corresponding to the horizontal nut slider 7. The positioning plate 11 can be vertically inserted downward into the horizontal nut slider 7, and can automatically detach from the horizontal nut slider 7 when the mobile trolley 3 moves upward.

[0026] At the same time, an optical axis 14 is also provided on the stand 1 parallel to the horizontal lead screw 5, and the horizontal nut slider 7 is sleeved outside the optical axis 14. The optical axis 14 guides the movement of the horizontal nut slider 7 and ensures stability during movement.

[0027] Through the control of the horizontal movement control motor 6, the horizontal lead screw 5 rotates to drive the horizontal nut to move horizontally, and then the horizontal nut slider 7 can drive the moving trolley 3 to move horizontally, and then the lower cover 4 is driven to move through the moving trolley 3.

[0028] The stand 1 is vertically provided with a screw lift 8 on the outside of the end of the support rail 2. The screw lift 8 is an adjustable speed motor that can realize the speed regulation of the lifting movement. The screw lift 8 is a four-axis screw lift, and each screw is provided with a lifting nut 9. The screws of the screw lift 8 rotate simultaneously, so that all the lifting nuts 9 are lifted and lowered at the same speed at the same time.

[0029] A lifting plate 10 is connected to the lifting screw nut 9, and a plurality of fixing pins 12 are vertically arranged on the lifting plate 10. The mobile trolley 3 is provided with fixing holes 13 at positions corresponding to the fixing pins 12 of the lifting plate 10. The lifting plate 10 can be detachably connected to the mobile trolley 3 by vertically inserting the fixing pins 12 into the fixing holes 13 of the mobile trolley 3, and the lifting plate 10 and the mobile trolley 3 are horizontally limited. The lifting plate 10 is controlled by the screw lift 8 to drive the mobile trolley 3 and the lower cover 4 to rise and fall. The initial position of the lifting plate 10 is located below the mobile trolley 3. When the lifting plate 10 drives the mobile trolley 3 to descend until the mobile trolley 3 falls on the support rail 2 and the positioning plate 11 is vertically inserted into the horizontal screw nut slider 7, the lifting plate 10 continues to descend to the initial position, and the fixing pins 12 are automatically disengaged from the fixing holes 13, and then the lifting plate 10 is disengaged from the mobile trolley 3, and the mobile trolley 3 can move horizontally.

[0030] Combination Figure 1-Figure 5 , and use it as follows:

[0031] 1. Installation process of the lower cover

[0032] The stand 1 is installed on the screw lift 8 directly below the vacuum furnace chamber 15, the lower cover 4 is fixed to the moving trolley 3, and the positioning plate 11 of the moving trolley 3 is vertically inserted downward into the horizontal screw nut slider 7 and connected to the horizontal screw nut slider 7, and is located in the horizontal initial position (such as Figure 1 As shown), the horizontal screw 5 is driven to rotate by the horizontal movement control motor 6, and the rotation of the horizontal screw 5 drives the horizontal nut slider 7 to move horizontally along the optical axis 14 and the horizontal screw 5, thereby driving the moving trolley 3 and the lower cover 4 to move directly below the vacuum furnace cavity 15.

[0033] When the mobile car 3 moves to the end, it enters the transfer state (such as Figure 2 and Figure 4 As shown), the screw lift 8 drives the lifting nut 9 and the lifting plate 10 to rise, and the fixing pin 12 of the lifting plate 10 is vertically inserted into the fixing hole 13 of the moving trolley 3, and continues to rise to drive the moving trolley 3 and the lower cover 4 to separate from the horizontal screw nut slider 7, and then continues to rise until the lower cover 4 and the lower part of the cavity 15 are in the installation state, and the lower cover 4 is installed. At this time, the lifting plate 10 is always located at the top, and the moving trolley 3 and the lower cover 4 are never separated (as shown in FIG. Figure 3 and Figure 5 as shown).

[0034] 2. The process of removing the lower cover

[0035] First, remove the lower cover 4 from the cavity 15, and the screw lift 8 drives the lifting nut 9 and the lifting plate 10 to descend until the positioning plate 11 of the moving trolley 3 is vertically inserted into the horizontal nut slider 7 and connected with the horizontal nut slider 7. The lifting plate 10 continues to descend to disengage the fixing pin 12 from the fixing hole 13 of the moving trolley 3, and then the horizontal screw 5 is driven to rotate by the horizontal movement control motor 6. The rotation of the horizontal screw 5 drives the horizontal nut slider 7 to move horizontally along the optical axis 14 and the horizontal screw 5 away from the screw lift 8 until the moving trolley 3 and the lower cover 4 move to the horizontal initial position.

[0036] It can be understood that the above specific description of the utility model is only used to illustrate the utility model and is not limited to the technical solution described in the implementation mode of the utility model. Ordinary technicians in the field should understand that the utility model can still be modified or replaced by equivalents to achieve the same technical effect; as long as the use requirements are met, they are within the protection scope of the utility model.
