Description

Technical Field

[0001] This utility model relates to the field of robot processing technology, specifically to a robot chassis shell processing and positioning device. Background Technology

[0002] With the rapid development of technology, robots are being used more and more widely in various fields. From industrial production to daily life, robots are everywhere. In order to meet the requirements of robot appearance and performance in different scenarios, the processing technology of robot shells has become increasingly important. Among them, polishing, as a traditional and effective surface treatment method, is widely used in the processing of robot shells. Polishing is a crucial step in the processing of robot shells, as it directly affects the appearance quality and performance of the product. The polishing process requires clamping structures, robotic arms, polishing heads, and protective shells.

[0003] A search revealed that patent document CN222155192U discloses a grinding device for processing robot shells, including a clamping mechanism. The clamping mechanism has a rotating mechanism on its surface, and a base mechanism on its surface. The clamping mechanism includes a first motor, with a drive gear rotatably connected to its rear. Two driven gears mesh with the surface of the drive gear. This grinding device, by activating the first motor, causes the drive gear to rotate the two driven gears in different directions, thereby causing two sliders threaded onto the surface of a lead screw to slide away from each other inside a groove. Ultimately, the surface of the airbag abuts against the inner wall of the robot shell, while the inner wall of the robot shell compresses the airbag, making it fit snugly against the inner wall of the robot shell, facilitating the clamping and fixing of robot shells of different shapes.

[0004] The aforementioned patent has the following drawbacks: it opens a sliding groove on the turntable for the movement of the clamping block. However, during grinding, the impurities generated during grinding can easily enter the base from this groove, which not only affects the use of the equipment but also makes it difficult to clean the impurities, causing the processing equipment to be easily affected. Therefore, a robot chassis shell processing and positioning device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a robot chassis shell processing and positioning device, which has the advantages of strong practicality and good protection effect, and solves the problem that impurities generated during grinding can easily affect the drive equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a robot chassis shell processing and positioning device, comprising a base consisting of a shell, a sealing cover and a bottom shell, wherein a positioning mechanism for processing the robot chassis shell is provided on the base;

[0007] The positioning mechanism includes a drive motor, a clamping block, a transmission gear, a lead screw, and a driven gear. The sealing cover has a sliding opening inside that communicates with the upper surface. The top of the clamping block extends through the sliding opening to the outside of the sealing cover. There are two clamping blocks, two driven gears, and two lead screws.

[0008] The sealing cover has a shielding structure inside for shielding the sliding opening. The shielding structure includes a take-up roller, a shielding cloth, and a take-up component. The take-up component consists of a motor, a drive wheel, and a drive belt. The sealing cover has a first mounting groove and a second mounting groove inside that communicate with the upper surface. A through-hole is provided between the first mounting groove and the sliding opening. The shielding cloth extends through the through-hole into the sliding opening and is fixed to the outer surface of the clamping block.

[0009] Furthermore, the housing is hollow inside, the sealing cover is fixedly installed on the top side of the housing, and the bottom shell is fixedly installed on the bottom side of the housing.

[0010] Furthermore, the bottom shell has a fixing groove that communicates with the interior of the shell. The drive motor is bolted into the fixing groove. The two clamping blocks and lead screws are symmetrically arranged. The two lead screw bearings are installed inside the shell. The transmission gear is fixedly installed on the output shaft of the drive motor. The two driven gears are fixedly installed on opposite ends of the two lead screws, and both driven gears mesh with the transmission gear.

[0011] Furthermore, each of the two clamping blocks is provided with an abutment structure on the side away from each other. The abutment structure includes a protective pad, a fixing ring, a return spring, and a guide rod. The return spring and the guide rod are both fixedly installed on the side of the protective pad near the clamping block. One side of the fixing ring is fixed to the other end of the return spring, and a fastening bolt is installed inside the fixing ring.

[0012] Furthermore, the reset spring is wrapped around the outer surface of the guide rod, and the clamping block has an extension groove inside that is adapted to the guide rod, with the end of the guide rod away from the pad extending into the extension groove.

[0013] Furthermore, the shielding structure comprises two first mounting slots, two take-up rollers, and two shielding cloths, with the two first mounting slots symmetrically arranged outside the sliding opening.

[0014] Furthermore, the two winding rollers are rotatably mounted in the two first mounting slots, and the two shielding cloths are wrapped around the outer surfaces of the two winding rollers, with the opposite sides of the two shielding cloths respectively fixed to the opposite side of the outer surface of the clamping block.

[0015] Furthermore, the motor is fixedly installed in the second mounting slot, and there are two drive wheels. The two drive wheels are respectively fixedly installed on the motor output shaft and the end of one of the take-up rollers. The end of the other take-up roller is equipped with a torsion spring, and the drive belt is connected between the two drive wheels.

[0016] Compared with the prior art, this utility model provides a robot chassis shell processing and positioning device, which has the following beneficial effects:

[0017] 1. The robot chassis shell machining positioning device, through precise control of the drive motor and transmission gears, can achieve fine adjustment of the distance between the two clamping blocks, thereby ensuring that the robot chassis shell is stably and accurately positioned during the machining process, which helps to improve machining accuracy and product quality.

[0024] 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.

[0025] Please see Figures 1 to 4 A robot chassis shell machining and positioning device includes a base 1 consisting of a shell 101, a sealing cover 102, and a bottom shell 103. A positioning mechanism 2 for machining the robot chassis shell is mounted on the base 1. The positioning mechanism 2 includes a drive motor 201, a clamping block 202, a transmission gear 203, a lead screw 204, and a driven gear 205. The sealing cover 102 has a sliding opening 1021 communicating with its upper surface. The top of the clamping block 202 extends through the sliding opening 1021 to the outside of the sealing cover 102. There are two clamping blocks 202, two driven gears 205, and two lead screws 204. When the drive motor 201 is activated, it drives the transmission gear 203 to rotate. The transmission gear 203 meshes with the driven gear 205, driving the lead screw 204 to rotate, thereby adjusting the distance between the two clamping blocks 202 and achieving machining and positioning of the robot chassis shell.

[0026] Specifically, the housing 101 is hollow inside, with the sealing cover 102 fixedly installed on the top side of the housing 101 and the bottom shell 103 fixedly installed on the bottom side of the housing 101. The bottom shell 103 has a fixing groove communicating with the interior of the housing 101. The drive motor 201 is bolted into the fixing groove. The two clamping blocks 202 and the lead screws 204 are symmetrically arranged. The bearings of the two lead screws 204 are installed inside the housing 101. The transmission gear 203 is fixedly installed on the output shaft of the drive motor 201, and two driven gears 205 are fixedly installed at opposite ends of the two lead screws 204, with both driven gears 205 meshing with the transmission gear 203. A limiting rod is installed inside the housing 101 to limit the movement of the two clamping blocks 202, allowing them to move linearly and improving the fixing effect.

[0027] To improve the fixing effect, in this embodiment, each of the two clamping blocks 202 has an abutment structure on its opposite side. The abutment structure includes a protective pad 206, a fixing ring 208, a return spring 209, and a guide rod 210. The return spring 209 and the guide rod 210 are both fixedly installed on the side of the protective pad 206 near the clamping block 202. One side of the fixing ring 208 is fixed to the other end of the return spring 209, and a fastening bolt is installed inside the fixing ring 208. The protective pad 206 in the abutment structure can make close contact with the surface of the clamped robot chassis shell. Through the elastic force of the return spring 209, the clamping block 202 generates a stable clamping force on the clamped object, which helps to prevent loosening caused by vibration or external force during processing and improves the stability of clamping. Among them, the return spring 209 surrounds the outer surface of the guide rod 210, and the clamping block 202 has an extension groove 207 adapted to the guide rod 210. The end of the guide rod 210 away from the pad 206 extends into the extension groove 207.

[0028] It should be noted that the protective pad 206 is typically made of a soft and abrasion-resistant material, such as rubber or silicone. It effectively protects the surface of the robot chassis housing from scratches or damage that may occur during clamping, ensuring the product's appearance quality and integrity. The retaining ring 208 is centrally located so that the guide rod 210 extends into the extension slot 207.

[0029] Understandably, the spring force of the return spring 209 can be adjusted to a certain extent according to the size of the object being clamped. Once the spacing of the clamping blocks 202 is adjusted to the correct position, the return spring 209 can automatically adapt to and fill the small gaps between the clamping blocks and the object being clamped, thereby ensuring a good clamping effect. This design allows the clamping device to be used with robot chassis housings of different sizes, improving the versatility and flexibility of the equipment.

[0030] In this embodiment, the sealing cover 102 is provided with a shielding structure 3 for shielding the sliding opening 1021. The shielding structure 3 includes a take-up roller 303, a shielding cloth 304, and a take-up component. The take-up component consists of a motor 306, a drive wheel 307, and a drive belt 308. The sealing cover 102 has a first mounting groove 301 and a second mounting groove 302 communicating with the upper surface. A through-hole 305 communicating between the first mounting groove 301 and the sliding opening 1021 is provided. The shielding cloth 304 extends through the through-hole 305 into the sliding opening 1021 and is fixed to the outer surface of the clamping block 202. The shielding structure 3 has two first mounting grooves 301, two take-up rollers 303, and two shielding cloths 304, and the two first mounting grooves 301 are symmetrically arranged outside the sliding opening 1021. Two take-up rollers 303 are rotatably mounted in two first mounting slots 301, and two shielding cloths 304 are wrapped around the outer surfaces of the two take-up rollers 303, with the opposite sides of the two shielding cloths 304 respectively fixed to the opposite outer surfaces of the clamping blocks 202. The shielding structure 3, through the design of the two take-up rollers 303 and the shielding cloths 304, can achieve efficient shielding of the sliding opening 1021. When the motor 306 is working, through the transmission wheel 307 and the transmission belt 308, one of the take-up rollers 303 is driven to rotate, thereby driving the shielding cloth 304 to perform take-up or unwinding operations. This ensures that the shielding cloth 304 can tightly adhere to the edge of the sliding opening 1021, effectively preventing debris, dust, and other impurities generated during processing from entering the robot chassis shell, ensuring the cleanliness of the processing environment and the quality of the product.

[0031] Specifically, the motor 306 is fixedly installed in the second mounting slot 302. Two drive wheels 307 are fixedly installed on the output shaft of the motor 306 and the end of one of the take-up rollers 303, respectively. A torsion spring is installed at the end of the other take-up roller 303. A drive belt 308 connects the two drive wheels 307. The two take-up rollers 303 are respectively installed in the two first mounting slots 301, and two shielding fabrics 304 are wrapped around the outer surface of the two take-up rollers 303. This design makes the winding and unwinding operations of the shielding fabrics 304 more flexible, allowing for easy adjustment of the shielding fabrics 304 according to processing requirements. Simultaneously, one take-up roller 303 is driven by the motor 306, while the other take-up roller 303 utilizes the deformation of the torsion spring for synchronous winding or unwinding, eliminating the need for an additional power source and reducing energy consumption.

[0032] It should be noted that one end of the take-up roller 303, which is connected to the drive wheel 307, extends into the second mounting groove 302. The bearing of the take-up roller 303 is installed in the first mounting groove 301. A maintenance plate with a shielding effect on the first and second mounting grooves 301 is bolted to the upper surface of the sealing cover 102. Battery modules are installed in both the second mounting groove 301 and the housing 101.

[0033] The working principle of the above embodiments is as follows:

[0034] In use, drive motor 201 and motor 306 are started. Drive motor 201 drives transmission gear 203 to rotate. Transmission gear 203 meshes with driven gear 205 to drive lead screw 204 to rotate, thereby adjusting the distance between the two clamping blocks 202 to achieve machining and positioning of the robot chassis shell. In addition, motor 306 drives one of the take-up rollers 303 to rotate through the transmission wheel 307 and transmission belt 208. The rotation of take-up roller 303 winds up and unwinds the shielding cloth 304. At the same time, the other take-up roller 303 uses the deformation of torsion spring to wind up and unwind synchronously, thereby achieving sealing and shielding of the slide 1021 and preventing debris generated during processing from entering the shell 101.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
