Description

Technical Field

[0001] This utility model relates to the field of robotics technology, and in particular to a chassis structure for a polishing robot. Background Technology

[0002] Polishing robots integrate advanced automation and intelligent technologies, playing a crucial role in the surface treatment of various stone materials such as marble and granite. They can complete polishing operations efficiently and precisely, significantly improving polishing quality and production efficiency. They are widely used in commercial buildings, high-end residences, luxury hotels, and other locations with extremely high requirements for decorative quality. In these applications, polishing robots handle a wide variety of stone types with significant differences in hardness, ranging from relatively soft marble to extremely hard granite. Different hardnesses of stone require vastly different polishing pressures. The polishing pressure of a polishing robot primarily comes from the robot's own weight and the added weight from the counterweight system. Therefore, the counterweight system, as a key component in adjusting polishing pressure, directly impacts the robot's polishing effect and applicability due to its rational design and flexibility.

[0003] In existing polishing robot designs, the counterweight is mostly encapsulated inside the chassis. Referring to the technical solution disclosed in patent document CN205835292U, the counterweight is installed in a groove on the bottom surface of the chassis and fixed by a cover plate.

[0004] However, given the significant weight of polishing robots, adjusting the counterweight from the bottom of the chassis often requires specialized lifting equipment or the collaboration of multiple people to lift or tilt the robot. This process not only increases the complexity and cost of operation, but also poses a significant safety hazard as the robot is prone to swaying, tilting, or even falling during operation. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a chassis structure for a polishing robot that facilitates counterweight adjustment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A chassis structure for a polishing robot, comprising: The chassis body has a counterweight compartment inside, and the opening of the counterweight compartment is exposed on the rear side of the chassis body. The fastener is disposed in the counterweight compartment; The counterweight has a slot that extends through the counterweight along its thickness and is exposed on its front end. The counterweight is inserted into the counterweight chamber through the opening of the counterweight chamber, and the fastener passes through the slot. The bin cover is used to open and close the opening of the counterweight bin.

[0007] In a preferred embodiment, the outer end face of the counterweight abuts against the bin cover.

[0008] In a preferred embodiment, the depth of the slot is greater than half the width of the counterweight.

[0009] In a preferred embodiment, there are two slots, which are spaced apart along the length of the counterweight. The number of fasteners is equal to the number of slots, and they correspond one-to-one.

[0010] In a preferred embodiment, the fastener includes a fixed head and a fixed tail connected together. The fixed tail is connected to the bottom surface of the counterweight chamber, and the fixed tail passes through the slot. The thickness direction of the counterweight is limited between the bottom surface of the counterweight chamber and the fixed head.

[0011] In a preferred embodiment, a plurality of the counterweights are stacked along the length of the fixing member.

[0012] The chassis body has two drive wheels on its bottom surface, and the counterweight compartment is located between the two drive wheels.

[0013] As a preferred embodiment, it also includes: The omnidirectional wheels are located on the front side of the chassis body.

[0014] A lifting assembly is disposed between the chassis body and the casters, which drives the casters to rise and fall.

[0015] In a preferred embodiment, the lifting assembly includes: Support frame, which is mounted on the chassis body; The power source is fixed to the support frame; A mounting bracket is connected between the power source and the caster wheels.

[0016] In a preferred embodiment, the fixing frame includes: A first mounting plate, which is connected to the power source; A second mounting plate is connected to the caster wheel, and the first mounting plate and the second mounting plate are perpendicular to each other.

Detailed Implementation

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0022] As mentioned in the background section, the existing method of mounting counterweights on the bottom of the chassis has significant drawbacks. Due to the large weight of the polishing robot, when it is necessary to adjust the counterweight from the bottom of the chassis, specialized lifting equipment or multiple people must be used to lift or flip the robot. This not only greatly increases the complexity and cost of operation, but also poses serious safety hazards due to the robot shaking, tilting, or even falling, and is not conducive to the flexible adjustment of the counterweight.

[0023] The chassis structure of the polishing robot provided in the embodiments of this utility model can solve this problem, which will be described in detail below. Please refer to... Figure 1 An embodiment of this utility model provides a chassis structure for a polishing robot, comprising: The chassis body 10 has a counterweight compartment 10a inside, and the opening 10a1 of the counterweight compartment 10a is exposed on the rear side of the chassis body 10. Fixing member 20, wherein the fixing member 20 is disposed in the counterweight chamber 10a; The counterweight 30 has a slot 31 that extends through the counterweight 30 along its thickness direction and is exposed on the front end face of the counterweight 30. The counterweight 30 is inserted into the counterweight chamber 10a through the opening 10a1 of the counterweight chamber 10a, and the fastener 20 passes through the slot 31. The cover 40 opens and closes the opening 10a1 of the counterweight compartment 10a.

[0024] Since the opening 10a1 of the counterweight compartment 10a is exposed on the rear side of the chassis body 10, the number of counterweight blocks 30 can be adjusted in the counterweight compartment 10a from the rear side of the chassis body 10. Compared with the prior art where the counterweight blocks are installed on the bottom surface of the chassis, the counterweight adjustment of this utility model is more convenient and faster, without the need for complex lifting equipment or multiple people to cooperate, reducing the difficulty and cost of operation, while improving the safety of operation. Furthermore, the counterweight block 30 is aligned with the fixing member 20 through the slot 31 on it. The counterweight block 30 is placed in the counterweight compartment 10a through the opening 10a1, and the counterweight block 30 is fixed by the fixing member 20. Finally, the entire installation or adjustment process is completed by closing the opening 10a1 through the compartment cover 40. The operation is simple and efficient.

[0025] like Figure 1 As shown, the counterweight 30 is cuboid, and the distance between the front and rear faces of the counterweight 30 defines the width of the counterweight 30. The slot 31 is exposed on the front face of the counterweight 30.

[0026] During the process of placing the counterweight 30 into the counterweight chamber 10a, the slot 31 on the front end of the counterweight 30 is first aligned with the fixing member 20. This alignment ensures that when the counterweight 30 is placed into the counterweight chamber 10a, the fixing member 20 slides into the slot 31 to fix the counterweight 30.

[0027] In this embodiment, the depth of the slot 31 is greater than half the width of the counterweight 30. This further improves the stability of the counterweight 30 when fixed in the counterweight chamber 10a.

[0028] Specifically, the outer end face of the counterweight 30 abuts against the compartment cover 40, that is, the width direction of the counterweight 30 is limited between the compartment cover 40 and the fixing member 20. At this time, the fixing member 20 can be located at the bottom of the slot 31. The distance between the fixing member 20 and the rear end face of the counterweight 30 is relatively short, so that the constraint effect of the fixing member 20 on the counterweight 30 is more direct and effective, further preventing the counterweight 30 from shaking or displacing.

[0029] like Figure 1 As shown, the fixing member 20 includes a fixing head 21 and a fixing tail 22 connected to each other. The fixing tail 22 is connected to the bottom surface of the counterweight chamber 10a. The fixing tail 22 passes through the slot 31. The thickness direction of the counterweight block 30 is limited between the bottom surface of the counterweight chamber 10a and the fixing head 21.

[0030] The fixing tail 22 can be threaded to the bottom surface of the counterweight chamber 10a, thereby adjusting the distance between the fixing head 21 and the bottom surface of the counterweight chamber 10a. Therefore, by reversing the fixing head 21, different numbers of counterweights 30 can be reliably fixed in the thickness direction when increasing or decreasing the number of counterweights 30. Multiple counterweights 30 are stacked along the length of the fixing member 20.

[0031] The fixing member 20 can be rotated by a wrench. The wrench is inserted horizontally into the counterweight chamber 10a through the opening 10a1 and acts on the fixing head 21 to drive the fixing member 20 to rotate in both directions.

[0032] like Figure 1 As shown, there are two slots 31, which are spaced apart along the length of the counterweight 30. The number of fasteners 20 is equal to the number of slots 31, and they correspond one-to-one.

[0033] The stability of the counterweight 30 in the counterweight chamber 10a is improved by increasing the number of the fasteners 20 and the slots 31.

[0034] In this embodiment, the weight of a single counterweight is 5-10 kg. When polishing marble surfaces, it is recommended to use 1 to 2 counterweights 30 to ensure a good polishing effect while avoiding damage to the marble surface due to excessive pressure. When polishing granite surfaces, due to their relatively high hardness, 2 to 3 counterweights 30 can be used to provide sufficient pressure and ensure polishing quality.

[0035] like Figure 1 As shown, the compartment cover 40 can be fixed to the rear side of the chassis body 10 by screws or other fasteners to close the opening 10a1. After removing the screws, the compartment cover 40 can be removed to open the opening 10a1. Of course, the compartment cover 40 can also be connected to the rear side of the chassis body 10 by hinge or snap-fit.

[0036] like Figure 1 As shown, the bottom surface of the chassis body 10 is provided with two drive wheels 50, and the counterweight compartment 10a is located between the two drive wheels 50.

[0037] like Figure 2 and Figure 3 As shown, the chassis structure of the polishing robot also includes: The caster wheel 60 is located on the front side of the chassis body 10.

[0038] A lifting assembly 70 is disposed between the chassis body 10 and the caster wheel 60, which drives the caster wheel 60 to rise and fall.

[0039] The casters 60 located on the front side of the chassis body 10 are used for robot movement. When the robot enters the grinding operation, in order to ensure the grinding effect, the casters 60 need to be raised by the lifting assembly 70. At this time, the scouring pad 90 under the chassis body 10 contacts the ground, thereby achieving effective grinding of the ground.

[0040] like Figure 2 and Figure 3 As shown, the lifting assembly 70 includes: Support frame 71, which is mounted on the chassis body 10; Power source 72, which is fixed on support frame 71; A mounting bracket 73 is connected between the power unit 72 and the caster wheel 60.

[0041] The support frame 71 is mounted on the chassis body 10. The support frame 71 includes a connecting support base plate 711 and a support base plate 712. The support base plate 711 and the support base plate 712 are perpendicular to each other. The support base plate 711 and the support base plate 712 are respectively connected to the chassis body 10, increasing the contact area between the support frame 71 and the chassis body 10, and further improving the stability of the installation.

[0042] The support frame 71 also includes a support side plate 713, which is connected between the support base plate 711 and the support bottom plate 712 to improve the structural stability of the support frame 71.

[0043] The power source 72 can be an electric motor or an electric cylinder, etc.

[0044] refer to Figure 2 The power source 72 is mounted on the support base plate 711 and is connected to the fixed frame 73 in a transmission manner to drive the fixed frame 73 and the casters 60 thereon to rise and fall.

[0045] The fixing frame 73 includes: A first mounting plate 731 is connected to the power source 72; The second mounting plate 732 is connected to the caster wheel 60, and the first mounting plate 731 and the second mounting plate 732 are perpendicular to each other. A connecting plate 733 is connected between the first mounting plate 731 and the second mounting plate 732.

[0046] like Figure 2 As shown, the lifting assembly 70 further includes: Guide members 74 are provided on the first mounting plate 731 and the support base plate 711. There are two guide members 74, which are respectively provided on both sides of the power 72 to ensure that the universal wheel 60 is raised and lowered more smoothly.

[0047] The guide member 74 includes a guide shaft 741, a linear bearing 742, and a support block 743. The two ends of the guide shaft 741 are respectively fixed on the support base plate 711 by the support block 743. The linear bearing 742 is sleeved on the guide shaft 741 and is connected to the first mounting plate 731.

[0048] refer to Figure 2The first mounting plate 731 needs to be connected to the power 72 and the two linear bearings 742 at the same time. Therefore, the first mounting plate 731 is relatively wide. Thus, a reinforcing rib 734 can be added between the first mounting plate 731 and the connecting plate 733 to further improve the stability of the structure.

[0049] refer to Figure 3 The lifting assembly 70 can be surrounded by the housing 80.

[0050] The embodiments described above are only used to illustrate the technical ideas and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. The scope of patent application of this utility model should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in this utility model still fall within the patent scope of this utility model.
