Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a floating lifting and positioning mechanism. Background Art

[0002] At present, in the production of automated equipment, it is common to improve the automation of production in the form of lines, improve efficiency and reduce the input of personnel. In the process of line production, carriers are needed to load products in different equipment to complete various processes. Therefore, it is very important to accurately and stably position various carriers in different workstations.

[0003] The jacking positioning mechanisms currently used are generally fixed positioning, which can only meet the scenarios where only one positioning is required. They are not suitable for scenarios where the positioning reference needs to be changed or two positionings are required. This can easily cause over-positioning, resulting in material jamming and inaccurate positioning. Utility Model Content

[0006] The floating support module includes a support seat and a carrier plate arranged on the support seat;

[0007] The support seat is provided with an installation opening at the end corner, and a compression spring, a support sleeve, and a pressure plate are sequentially arranged in the installation opening; one end of the support sleeve is sleeved on the compression spring, and the other end passes through the pressure plate and is placed in the carrier plate;

[0008] The pressing plate is provided with a conical hole, and correspondingly, the contact surface between the supporting sleeve and the conical hole is set as a conical surface, and the conical surface is in contact with the conical hole to enable the carrier plate to float in all directions;

[0009] Positioning pieces are also provided at both ends of the carrier for positioning with the carrier placed on the carrier.

[0010] Preferably, the lifting module includes a mounting seat, a driving motor arranged on the mounting seat, linear guide rails arranged on both sides of the mounting seat, a synchronous belt assembly arranged at the output end of the driving motor, a screw rod arranged at one end on the synchronous belt assembly, a screw rod nut arranged on the screw rod, and a sliding seat arranged on the screw rod nut and slidably connected to the linear guide rails.

[0015] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0016] The technical solution of the utility model has the following beneficial effects:

[0017] The floating mechanism of the utility model adopts three components: a supporting copper sleeve, a compression spring and a pressure block. The structure is simple, the processing difficulty is low, and the processing cost can be reduced. The conical surface is simply used to increase the degree of freedom, and the supporting copper sleeve is pre-pressed by the compression spring to make its conical surface fit with the conical surface of the conical hole of the pressure block.

[0032] Reference Figures 1 to 8 The utility model provides a floating lifting and positioning mechanism, comprising: a lifting module 1, and a floating support module 2 arranged at the output end of the lifting module 1, wherein the floating support module 2 can be driven to lift by the lifting module 1;

[0033] The floating support module 2 includes a support seat 201 and a carrier plate 202 disposed on the support seat 201;

[0034] The support seat 201 is provided with an installation opening 2010 at the end corner, and a compression spring 204, a support sleeve 205, and a pressure plate 206 are sequentially arranged in the installation opening 2010; one end of the support sleeve 205 is sleeved on the compression spring 204, and the other end passes through the pressure plate 206 and is placed in the installation opening of the carrier plate 202. The support sleeve 205 is made of copper, and the copper sleeve 205 is pre-pressed by the compression spring 204 to make its conical surface 2050 fit with the conical hole 2060 of the pressure block 206. Due to the contact of the conical surfaces, the carrier plate 202 can float in all directions;

[0035] The pressing plate 206 is provided with a conical hole 2060. Correspondingly, the contact surface between the support sleeve 205 and the conical hole 2060 is set as a conical surface 2050. The conical surface 2050 is in contact with the conical hole 2060 to enable the carrier plate 202 to float in all directions.

[0036] The two ends of the carrier plate 202 are also provided with positioning members 203 for positioning the carrier 3 placed on the carrier plate 202. The positioning members 203 are configured as positioning pins, which can effectively position the carrier 3 and facilitate accurate installation of the carrier 3 on the carrier plate 202.

[0037] Furthermore, the lifting module 1 includes a mounting base 101, a driving motor 102 arranged on the mounting base 101, linear guides 105 arranged on both sides of the mounting base 101, a synchronous belt assembly 103 arranged at the output end of the driving motor 102, a screw rod 104 with one end arranged on the synchronous belt assembly 103, a screw nut arranged on the screw rod 104, and a sliding seat 106 arranged on the screw nut and slidably connected to the linear guide 105. The synchronous belt assembly 103 is composed of a synchronous wheel and a synchronous belt. The working principle of the lifting module 1 is that the driving motor 102 drives the synchronous belt assembly 103 to move, thereby driving the screw rod to move, and then driving the screw nut to move, and then driving the sliding seat 106 installed on the screw nut to slide along the linear guide 105 to lift the floating support module 2. Photoelectric limit switches 109 are also provided on both sides of the mounting seat 101. Correspondingly, photoelectric sensing sheets 110 corresponding to the photoelectric limit switches 109 are provided on both sides of the sliding seat 106. The photoelectric limit switches 109 and the photoelectric sensing sheets 110 are used together to limit the sliding position of the sliding seat 106.

[0038] Furthermore, the top of the sliding seat 106 is also provided with a guide sleeve 107 and a buffer spring 108 placed next to the guide sleeve 107. The guide sleeve 107 plays a guiding role, which can make the floating support module 2 move along the direction of the guide sleeve when lifting. The buffer spring 108 is used to prevent the impact force of the lifting module 1 from being too much and damaging the components when lifting the floating support module 2. The bottom of the support seat 201 is also provided with a guide shaft 210 adapted to the guide sleeve 107; the guide shaft 210 is correspondingly inserted into the guide sleeve 107, and the bottom plate of the support seat 201 is in contact with the buffer spring 108. The guide shaft 210 and the guide sleeve 107 are used together to play a guiding role, which can prevent the support seat 201 from deviating during the lifting process; the support seat 201 is also provided with a position sensor 4, which is opposite to the carrier 3 above, and is used to sense the position of the carrier 3.

[0039] Working principle of this utility model:

[0040] When the carrier 3 is received, the first positioning is performed using the positioning hole at the bottom of the carrier 3 as the positioning reference and placed in the positioning piece 203 of the carrier plate 202;

[0041] When the lifting module 1 is moved to the position where the carrier is finally to be positioned, the lifting module 1 lifts the carrier 3;

[0042] The second positioning uses the positioning hole on the top of the carrier as the positioning reference, inserts other positioning pins, and the carrier completes the positioning.

[0043] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
