Embodiment 1

[0036] Such as figure 2 Shown is a schematic diagram of the overall structure of the screw reverse taper connection structure 3 in Embodiment 1, as image 3 Shown is a schematic structural view of the inverted conical frustum 4 .

[0037] The top of lifting platform 1 has first circular hole 7, and the inner diameter of first circular hole 7 is greater than the outer diameter of leading screw 2, and leading screw 2 can pass first circular hole 7.

[0038] The lower part of the lifting platform 1 has a first circular platform cavity 9, the inner diameter of the first circular platform cavity 9 is arranged in a small upper part and a larger lower part, wherein the inner diameter of the uppermost part of the first circular platform cavity 9 is greater than the inner diameter of the first circular hole 7, The first abutting surface 10 is formed at the uppermost part of the first circular frustum cavity 9 .

[0039] In the first conical frustum cavity 9, an inverted conical frus...

Embodiment 2

[0048] Such as Figure 4 Shown is a schematic diagram of the overall structure of the screw reverse taper connection structure 3 in the second embodiment, as image 3 Shown is a schematic structural view of the inverted conical frustum 4 .

[0049] The top of lifting platform 1 has first circular hole 7, and the inner diameter of first circular hole 7 is greater than the outer diameter of leading screw 2, and leading screw 2 can pass first circular hole 7.

[0050] The lower part of the lifting platform 1 has a step hole 11, which is used to accommodate a connecting block 12 with a stepped shape. After the connecting block 12 is placed in the step hole 11, the lifting platform 1 and the connecting block are connected by fasteners such as bolts (not shown). 12 connected together.

[0051] The upper part of the connecting block 12 has a second round hole 13 , the inner diameter of the second round hole 13 is larger than the outer diameter of the lead screw 2 , and the lead scr...

Embodiment 3

[0062] Such as Figure 5 Shown is another schematic structural view of the inverted cone truncated cone 4 .

[0063] In addition to having the same structure as that in Embodiment 1 and Embodiment 2, the inverted cone truncated 4 also has a guide sleeve 15 on the top surface of the inverted cone truncated 4, and the mounting hole 5 runs through the guide sleeve 15. After the inverted cone truncated 4 When applied to the first embodiment, the guide sleeve 15 can be inserted into the first circular hole 7, and when the inverted cone 4 is applied to the second embodiment, the guide sleeve 15 can be inserted into the first circular hole 7, the second In two circular holes 13 ;

[0064] Since the guide sleeve 15 is arranged on the upper top surface of the inverted cone 4, better positioning can be achieved when the inverted cone 4 is installed.

Abstract

The present invention is applicable to the technical field of multi-axis synchronous lifting, and provides a lead screw inverted cone connection structure, including a lifting platform, an inverted cone circular platform, and a screw rod. After passing through the first circular hole, it is connected with the inverted cone; the lower part of the lifting platform has a first circular platform cavity, and the inner diameter of the first circular platform cavity is arranged in a small upper part and a larger lower part, and the inverted cone circular platform is accommodated in the In the cavity of the first truncated cone, there is a certain gap between the outer peripheral surface of the inverted cone truncated cone and the inner peripheral surface of the first truncated circular cavity. Since there is a certain gap between the outer peripheral surface of the inverted cone and the inner peripheral surface of the first circular platform cavity of the lifting platform, the verticality of each screw has a certain amount of adjustment, so it is easier to ensure the synchronization of each screw The ground drives the lifting platform to rise vertically.

Description

technical field [0001] The invention belongs to the technical field of multi-axis synchronous lifting, and in particular relates to a lead screw reverse taper connection structure. Background technique [0002] The industrial production of the lifting platform has been widely used. The lifting platform in the prior art mainly has the following two structures: one way is to adopt a flexible connection design, use multiple hanging chains to hang the platform, and then hoist it as a whole; the other way is , part of which adopts a rigid connection design to support the platform on a folding arm composed of multiple parallelograms, and the folding arm is driven by electric or hydraulic pressure to lift the platform. Among the above lifting platforms, due to the use of multiple chains for suspension or multiple support arms for support, the lifting platforms have the following defects: poor flatness of the table surface, unstable pressure, and small load capacity. [0003] At pr...
