Description

Technical Field

[0001] This utility model relates to the field of long-stroke screw transmission structure, specifically a screw lifting device for a glass edging machine. Background Technology

[0002] A lead screw is a mechanical transmission element that converts rotary motion into linear motion. It is widely used in various industrial equipment and precision instruments. Currently, there is a market demand for a large-size glass edging processing device. Edging processing devices with a stroke exceeding 6 meters are unusable due to mechanical structure limitations.

[0003] The publication number CN216742687U discloses a ball screw support frame, including a base and a support seat for supporting the screw. The base is fixedly mounted on a workbench, and the support seat is mounted on the base.

[0004] The aforementioned ball screw support frame can adjust the support height of the support base to support the ball screw to be tested according to the needs of different testing devices. However, when rotation is required during the support process, friction occurs between the contact surfaces of the screws, making it inconvenient to adjust the support spacing to support screws of different diameters. Furthermore, it is inconvenient to provide corresponding cushioning when supporting the screw in the downward position, and the lifting spring force is not easy to adjust. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-4 The glass edging machine screw lifting device includes a base plate 1 and a bearing seat 2. A rotating mechanism 3 is installed on the top of the bearing seat 2, and a support mechanism 4 is installed on the bottom of the base plate 1.

[0025] See Figure 2 Furthermore, the rotating mechanism 3 includes two connecting seats 5, each of which has two transverse bearings 6 installed on its exterior. The two connecting seats 5 are mounted on the top of the base plate 1. The top of the base plate 1 is connected to and installed with longitudinal bearings 7 at both ends. Two guide rails 8 are fixedly installed on both sides of the base plate 1. Several positioning holes 9 are opened on both sides of the base plate 1. Two sliders 10 are movably installed on both sides of the base plate 1 and outside the guide rails 8. Positioning bolts 11 are movably connected through the outside of the sliders 10.

[0026] The two ends of the connecting seat 5 are respectively connected to the top of the two sliders 10 on both sides by bolts. The transverse bearing 6 is located outside the connecting seat 5 and is rotatably set. The transverse bearing 6 on the top of the two connecting seats 5 is used for the support and rotation of the lead screw.

[0027] The guide rail 8 has a trapezoidal cross-section, and the slider 10 is located on both sides of the base plate 1 and is slidably set through the guide rail 8. The distance between the two connecting seats 5 is adjusted by sliding the slider 10.

[0028] The positioning bolt 11 is threaded through the inside of the slider 10, and the inner end of the positioning bolt 11 is snapped into the positioning hole 9. The slider 10 and the bearing seat 2 are fixed together by the snapping of the positioning bolt 11 and the positioning hole 9.

[0029] Specifically, the slider 10 slides through the guide rail 8 to facilitate the adjustment of the distance between the two connecting seats 5. The lead screw is supported and rotated by the transverse bearing 6, which facilitates the rotation of the lead screw and reduces friction. By sliding the slider 10, the positioning bolt 11 engages with the positioning hole 9, which is suitable for supporting lead screws of different diameters.

[0030] Example 2

[0031] See Figure 3 Furthermore, based on Embodiment 1, the bearing seat 2 is further provided with two guide rods 14 and a positioning rod 15 fixedly installed at its bottom. The support mechanism 4 includes two rod sleeves 12 and a fixed sleeve 13. Both rod sleeves 12 and the fixed sleeve 13 are fixedly installed at the bottom of the base plate 1. The guide rods 14 and the positioning rod 15 pass through the inside of the rod sleeves 12 and the fixed sleeve 13, respectively. A spring 16 is sleeved on the outside of the positioning rod 15. A screw tube 17 is connected and installed through the bottom of the fixed sleeve 13. A rod groove 18 is opened at the top of the screw tube 17. A knob 19 is fixedly installed at the bottom of the screw tube 17.

[0032] The guide rod 14 and the positioning rod 15 are respectively slidably installed inside the rod sleeve 12 and the fixed sleeve 13. The upper and lower ends of the spring 16 are respectively attached to the bottom of the bearing seat 2 and the top of the screw tube 17. The bearing seat 2 is automatically lifted upward under the action of the spring 16.

[0033] The screw tube 17 passes through the bottom of the fixed sleeve 13 and is threaded. The positioning rod 15 is located inside the rod groove 18 and is slidably disposed. The lifting force of the spring 16 can be adjusted by adjusting the screw tube 17.

[0034] Specifically, the two guide rods 14 are used for guiding the lifting and lowering of the bearing seat 2. The bearing seat 2 automatically lifts the lead screw upward through the spring 16. Rotating the knob 19 causes the screw tube 17 to slide up and down under the action of the thread, and compresses or extends the spring 16 to adjust the lifting force of the spring 16.

[0035] In actual operation, the two connecting seats 5 are respectively installed on the top of the two corresponding sliders 10 by bolts. The glass edging machine screw drops down and is located in the transverse bearings 6 on the two connecting seats 5. The transverse bearings 6 support the screw so as to facilitate the rotation of the screw and reduce friction.

[0036] When supporting lead screws of different diameters, rotate the positioning bolt 11 to disengage the positioning bolt 11 on the outer side of the two corresponding sliders 10 in the connecting seat 5 from the positioning hole 9, push the connecting seat 5 to make the sliders 10 slide through the guide rail 8, change the distance between the two connecting seats 5, slide to the designated position and fix it by the engagement of the positioning bolt 11 with the positioning hole 9, so as to adapt to lead screws of different diameters.

[0037] During lifting and adjustment, the bearing seat 2 lifts the lead screw upward under the action of the spring 16, and guides the lifting and lowering through the two guide rods 14. When adjusting the lifting force of the spring 16, the knob 19 is rotated to make the screw tube 17 slide up and down under the action of the thread, compressing or extending the spring 16, thereby changing the elastic force of the spring 16 to support lead screws of different weights and provide corresponding support force.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
