Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a grinding device for ship welds. Background Technology

[0002] Sectional welding is an important process in shipbuilding, and ensuring welding quality is crucial to the safety and stability of the ship. After welding is completed, workers need to use hand-held grinders to grind the weld seams. Prolonged hand-held grinding is extremely tiring for users and significantly reduces grinding efficiency.

[0003] Chinese patent CN 221539191 U discloses a grinding equipment for weld seams in ship sections, which facilitates workers to quickly grind weld seams and improves grinding efficiency. However, during the grinding process, it is still necessary to manually push the sliding frame to move the grinding wheel along the weld seam surface, which is not very convenient to use. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a ship weld grinding device that is easy to use, does not require manual pushing by workers, and reduces labor intensity.

[0005] This utility model is achieved by the following solution: a ship weld grinding device, including a track beam, with fixing mechanisms at both ends of the track beam, and a slide block that can reciprocate along the length of the track beam on the track beam. A grinding motor with its drive end facing downward is installed on the slide block, and a grinding wheel is connected to the main shaft of the grinding motor. Synchronous pulleys are rotatably installed at both ends of the track beam, and a synchronous belt is connected between the two synchronous pulleys. A clamping frame connected to one side of the synchronous belt is provided on the slide block, and one of the synchronous pulleys is driven by a moving motor.

[0006] Furthermore, the fixing mechanism includes a pair of retractable support legs hinged to the end of the track beam, with an electromagnet connected to the lower end of each support leg.

[0007] Furthermore, the support foot is composed of an upper support plate and a lower support plate that are sleeved together and can slide relative to each other. The upper support plate is sleeved on the outside of the lower support plate. A limit bolt A is provided through the lower part of the upper support plate. A number of limit holes A are provided at intervals on the lower support plate. The limit bolt passes through one of the limit holes.

[0008] Furthermore, the track beam has a hollowed-out groove in the middle that runs along its length. The main shaft of the grinding motor passes through the slide and the hollowed-out groove and is connected to a sleeve. The sleeve has a connecting shaft that can slide relative to it. The lower end of the connecting shaft extends out from the lower end of the sleeve and is connected to the grinding wheel through an elastic mechanism.

[0009] Furthermore, the elastic mechanism includes a connecting seat fixedly connected to the lower end of the connecting shaft, a shaft body that can slide up and down relative to the connecting seat at the lower end, a support plate fixedly connected to the outer periphery of the lower end of the shaft body, a spring sleeved on the outside of the shaft body and sandwiched between the connecting seat and the support plate, and a threaded hole for connecting a grinding wheel at the lower end of the shaft body.

[0010] Furthermore, a limiting bolt B is provided through the lower part of the sleeve, and a plurality of limiting holes B are provided at intervals on the connecting shaft, through which the limiting bolt B passes.

[0011] Furthermore, the main shaft of the mobile motor is coaxially connected to the axle of the driven synchronous belt pulley.

[0012] Compared with the prior art, the present invention has the following advantages: The present invention's ship weld grinding device uses a mobile motor to drive the slide block to move through a synchronous belt, which in turn drives the grinding wheel to move along the weld surface for grinding. The grinding wheel is driven to rotate by the grinding motor, which is convenient to use and does not require manual pushing by workers, thus reducing labor intensity. Since the length and angle of the support legs can be changed, it is beneficial to install the grinding device on both sides of the inclined surface to grind welds at a certain angle range of inside or outside corners, which has good versatility.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below through specific embodiments and related drawings. Attached Figure Description

Detailed Implementation

[0021] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] like Figures 1-6 As shown, a ship weld grinding device includes a track beam 100, with fixing mechanisms 200 at both ends. A slide block 300, capable of reciprocating along the length of the track beam, is mounted on the track beam 100. A grinding motor 310 with its drive end facing downwards is mounted on the slide block 300, and a grinding wheel 400 is connected to the spindle of the grinding motor 310. Synchronous pulleys 500 are rotatably mounted at both ends of the track beam 100, and a synchronous belt 510 connects the two pulleys. A clamping frame 310 connected to one side of the synchronous belt is provided on the slide block, with one pulley driven by a moving motor 600. This ship weld grinding device utilizes a moving motor to drive the slide block via a synchronous belt, thereby driving the grinding wheel to move along the weld surface for grinding. The grinding wheel is driven to rotate by the grinding motor, making it convenient to use, eliminating the need for manual pushing by workers, reducing labor intensity, and preventing workers from approaching the grinding wheel and coming into contact with grinding dust.

[0024] In this embodiment, the slide block and the track beam can be slidably engaged, or they can be engaged by rolling rollers to reduce friction.

[0025] In this embodiment, the fixing mechanism 200 includes a pair of retractable support legs 210 hinged to the end of the track beam, and an electromagnet 220 is connected to the lower end of the support legs. The entire grinding device is fixed to the ship weld by adsorption using four electromagnets at both ends.

[0026] In this embodiment, the support foot consists of an upper support plate 211 and a lower support plate 212 that are sleeved together and can slide relative to each other. The upper end of the upper support plate 211 is hinged to the end of the track wheel, and the upper support plate is sleeved outside the lower support plate. A limit bolt A213 is provided through the lower part of the upper support plate, and several limit holes A are provided at intervals on the lower support plate. The limit bolt passes through one of the limit holes. The length can be adjusted by sliding the lower support plate after the limit bolt A is pulled out, and then fixed by repositioning the limit bolt A. Since the length and angle of the support foot can be changed, it is beneficial to install the grinding device on the two inclined surfaces for grinding welds at internal or external corners within a certain angle range, such as... Figure 5 , 6 As shown, it has good versatility and is generally suitable for inside corners of 120~180° and outside corners of 180~210°.

[0027] In this embodiment, the track beam 100 has a hollowed-out groove in the middle along the length direction. The main shaft of the grinding motor passes through the slide and the hollowed-out groove and is connected to a sleeve 330. The sleeve has a connecting shaft 340 that can slide relative to it. The lower end of the connecting shaft extends from the lower end of the sleeve and is connected to the grinding wheel through an elastic mechanism. The cross-section of the connecting shaft is polygonal, and the cross-section of the inner hole of the sleeve is also polygonal, which can maintain power transmission. The height of the grinding wheel can be adjusted by sliding and extending the connecting shaft.

[0028] In this embodiment, the elastic mechanism includes a connecting seat 350 fixedly connected to the lower end of the connecting shaft. A shaft 360, capable of sliding up and down relative to the connecting seat, is connected to the lower end of the connecting seat. A support plate 361 is fixedly connected to the outer periphery of the lower end of the shaft. A spring 370 is sleeved on the outside of the shaft, sandwiched between the connecting seat and the support plate. A threaded hole for connecting a grinding wheel is provided at the lower end of the shaft. The spring's thrust ensures the grinding wheel remains in contact with the weld surface. Furthermore, in areas with thicker welds, the grinding wheel can compress the spring and automatically retract, adaptively adjusting its position to prevent the grinding wheel from jamming or prematurely failing due to excessive grinding depth.

[0029] The grinding wheel has a screw at the top that connects to the threaded hole at the bottom of the shaft. Different types of grinding wheels can be used to grind different parts.

[0030] In this embodiment, the connecting seat 350 has a cavity inside, and the lower end of the connecting seat has a slot that extends through the cavity. The slot and the cross-section of the shaft are a matching polygon. The upper end of the shaft 360 extends into the cavity and is fixedly connected to an annular baffle for locking at the lower end of the cavity.

[0031] In this embodiment, a limiting bolt B380 is provided through the lower part of the sleeve, and several limiting holes B are provided at intervals on the connecting shaft. The limiting bolt B passes through one of the limiting holes B. The length can be adjusted by sliding the connecting shaft after the limiting bolt B is pulled out, and then the limiting bolt B is fixed again after adjustment.

[0032] In this embodiment, the main shaft of the mobile motor is coaxially connected to the axle of the driven synchronous pulley.
