Description

Technical Field

[0001] The present invention relates to the technical field of ship structure processing equipment, and particularly relates to a fixing and assisting device for boring and processing an ear plate assembly. Background Art

[0002] The ear plate assembly is an important component in large-scale steel structure manufacturing projects such as quay cranes, bulk cargo, and ships. Due to design requirements, the pin holes (hole walls) of the ear plate assembly need to be processed before being assembled and welded to the main steel structure. The processing equipment is generally a horizontal boring machine. According to the operation process, before processing the pin holes, it is necessary to first adjust the relative positions of the ear plate assembly, the boring machine, and the boring bar, and accurately position and firmly fix the boring bar and the ear plate assembly. Since the boring machine itself does not have a mechanism and function for fixing the ear plate assembly and the boring bar, a welding fixing mode has been adopted. Angle steel or other profiles are used to rigidly connect the ear plate assembly to the boring machine and the boring machine base plate by pushing or pulling to achieve the purpose of fixing the ear plate assembly and the boring bar. The disadvantage of this fixing mode is that the operation is cumbersome with many steps, the labor intensity is high, it relatively wastes labor, electric energy, welding materials, and auxiliary materials, and the soot generated by welding will also cause a certain degree of pollution and impact on the workshop air environment.

[0080] For the purposes of making the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention fall within the scope of protection of the present invention.

[0081] Unless otherwise defined, the technical terms or scientific terms used in the present invention shall have the ordinary meanings as understood by those of ordinary skill in the art to which the present invention pertains. The "first", "second" and similar terms used in the present invention do not denote any order, quantity or importance, but are only used to distinguish different components. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left" and "right" are only used to indicate relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationships will also change accordingly.

[0082] First, the ear plate assembly boring and machining fixing and assisting device according to the embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0083] As Figures 1 to 20As shown in the figure, the fixing and assisting device for boring the ear plate assembly according to the embodiment of the present invention (hereinafter sometimes simply referred to as the "assisting device") is used to connect and fix the output end of the boring machine 900, and includes: a base 100, a boring bar positioning device 200, an ear plate assembly fixing device 400, and a support rod 500.

[0084] Among them, the boring bar positioning device 200 is arranged on the base 100, and the boring bar positioning device 200 is formed with a positioning hole 2252 that allows the boring bar 800 in the boring working state to pass through.

[0085] The ear plate assembly fixing device 400 is arranged on the base 100 and is arranged relative to the boring bar positioning device 200. The ear plate assembly fixing device 400 is used to clamp and fix the ear plate assembly 1100.

[0086] One end of the support rod 500 is connected to the ear plate assembly fixing device 400, and is used to connect and fix the fixing and assisting device for boring the ear plate assembly and the boring machine 900 into one body.

[0087] According to the assisting device of the present invention, it is fixedly connected to the output end of the boring machine 900 during processing. Through the boring bar positioning device 200 and the ear plate assembly fixing device 300 sequentially arranged on its base 100, the relative position state adjustment and fixation among the boring bar, the ear plate assembly and the boring machine can be quickly realized before the boring machine processing. The installation and processing are convenient and reliable, saving the cumbersome steps of the original processing mode and further improving the production efficiency. In addition, through the reliable fixation of the boring bar and the ear plate assembly relative to the boring machine by the boring bar positioning device and the ear plate assembly fixing device of the present invention, the machining accuracy is also guaranteed.

[0088] As an example, as Figure 9 shown, the two ends of the support rod 500 are respectively provided with a fixing round hole 510 and a fixing waist-shaped hole 520. The fixing round hole 510 end is fixedly connected to the connecting ear plate on the ear plate assembly fixing device 400, and is connected to the boring machine 900 in a position-adjustable manner through the fixing waist-shaped hole 520.

[0089] Furthermore, as Figures 4 - 7 shown, the boring bar positioning device 200 may include: a guiding frame 210 and a fixing mechanism 220.

[0090] Among them, the guiding frame 210 includes: a bottom plate 211 and a guiding seat 212. The bottom plate 211 is installed on the base 100. The guiding seat 212 is vertically arranged on the top surface of the bottom plate 211. The guiding seat 212 is plate-shaped, and a first through hole 219 is formed in the middle of the guiding seat 212, and the two side edges are turned inward to form guiding grooves 213.

[0091] The fixing mechanism 220 includes: a fixing mechanism main board 225 and a coarse adjustment component. Both ends of the fixing mechanism main board 225 are fitted in the guiding grooves 213 and are fixedly mounted on one side of the guiding frame 210 in a vertically adjustable manner. A positioning hole 2252 is formed at a position corresponding to the first through hole 219 of the guiding seat 212 on the fixing mechanism main board 225. The coarse adjustment component includes a lifting lead screw 222, a lifting lead screw bracket 223, and a lifting lead screw pair handle 221. The bottom end of the lifting lead screw 222 is fixedly connected to the top surface of the fixing mechanism main board 225, and the upper end of the lifting lead screw 222 sequentially passes through the lifting lead screw bracket 223 and the lifting lead screw pair handle 221. The lifting lead screw bracket 223 is fixed on the ear plate assembly fixing device 400, and the bottom surface of the lifting lead screw pair handle 221 abuts against the upper surface of the lifting lead screw bracket 223.

[0092] Thus, for the boring bar positioning device 200 according to this embodiment, by moving the lifting lead screw 222 up and down, the fixing mechanism main board 225 can be driven to move smoothly up and down along the guiding frame 210. That is to say, the position of the positioning hole 2252 on the fixing mechanism main board 225 in the height direction is changed, so that the position of the boring bar 800 in the height direction can be adjusted to meet the processing requirements of different ear plate assemblies.

[0093] Furthermore, one or more fixing mechanism tightening screw holes 214 are formed on the outer plate surface of the guiding groove 213 in the vertical direction. The fixing mechanism main board 225 is tightened on the guiding seat 212 by screwing a fixing mechanism tightening bolt into the fixing mechanism tightening screw hole 214. Thus, when the fixing mechanism main board 225 is adjusted to a predetermined height on the guiding frame 210, the fixing mechanism main board 225 is tightened on the guiding seat 212 by screwing the fixing mechanism tightening bolt into the fixing mechanism tightening screw hole 214 to ensure that the boring bar 800 does not change its position during the processing.

[0094] Furthermore, elongated holes 215 extending in the vertical direction are formed on both sides of the first through hole 219 on the guiding seat 212. Mounting holes 2254 are formed at positions on the fixing mechanism main board 225 corresponding to the elongated holes 215. The fixing mechanism main board 225 is fixed on the guiding seat 212 by passing mounting bolts through the mounting holes 2254 and the elongated holes 215. Through the screwing connection of the mounting holes 2254 and the elongated holes 215, the middle part of the fixing mechanism main board 225 can be tightened and fixed to the guiding seat 212, further improving the reliability of the positioning of the fixing mechanism main board 225.

[0095] Further, two lifting lead screw bracket fixing screw holes 216 are provided in the middle of the top surface of the guiding seat 212, and the lifting lead screw bracket 223 is fixed on the top surface of the guiding seat 212 by screwing bolts into the lifting lead screw bracket fixing screw holes 216. Fixing the lifting lead screw bracket 223 on the top surface of the guiding seat 212 facilitates the rough adjustment operation by rotating the handle 221 of the lifting lead screw pair. In addition, the lifting lead screw bracket 223 can be set in a convex shape, for example. The lifting lead screw 222 passes through the boss 2231 of the convex-shaped lifting lead screw bracket 223, and bracket fixing screw holes 2232 are provided at both ends of the convex shape. The lifting lead screw bracket 223 is fixed on the top surface of the fixing mechanism main board 225 by screwing into the bracket fixing screw holes 2232. This structure is simple, and while ensuring the height adjustment function of the lifting lead screw 222, interference between the fixing mechanism main board 225 and the guiding seat 212 does not occur.

[0096] Further, an inverted T-shaped notch 2251 is formed at the top end of the fixing mechanism main board 225. A T-shaped block 224 is fitted in the inverted T-shaped notch 2251. A threaded hole is formed at the top end of the T-shaped block 224, and the bottom end of the lifting lead screw 222 is screwed into the threaded hole. Anti-detachment strips 2241 are provided on both sides of the T-shaped block 224, and the anti-detachment strips 2241 are detachably fixed on the fixing mechanism main board 225. Here, a detachable connection between the fixing mechanism main board 225 and the lifting lead screw 222 is formed, with a firm structure and convenient replacement of worn parts.

[0097] Further, the fixing mechanism 220 may further include: a fine adjustment component and multiple sets of adjustment components.

[0098] Among them, the fine adjustment component includes a nylon sleeve 227. A second through hole 2271 for the boring bar 800 to pass through is formed in the middle of the nylon sleeve 227, and the second through hole 2271 communicates with the positioning hole 2252.

[0099] Each set of adjustment components includes a nylon sleeve tightening screw support 226 and a nylon sleeve tightening screw 228. Multiple sets of adjustment components are respectively distributed at intervals in the circumferential direction of the nylon sleeve 227, and the nylon sleeve tightening screw support 226 is fixed on the middle plate surface of the fixing mechanism main board 225. The nylon sleeve tightening screw 228 is screwed into the nylon sleeve tightening screw support 226 and its end abuts against the nylon sleeve 227.

[0100] That is to say, as Figures 4 - 7 shown, a nylon sleeve 227 is arranged at a position corresponding to the positioning hole 2252 on one side of the fixing mechanism main board 225. The nylon sleeve 227 can move up, down, left, and right in the vertical plane through multiple sets of adjustment components in the circumferential direction, so as to further adjust the position of the boring bar 800 by fine-tuning the position of the second through hole 2271 on the nylon sleeve 227.

[0101] By providing the fine adjustment component, through multiple sets of adjustment components, such as Figure 4 ,Figure 6 The four sets of adjusting components shown respectively adjust the position of the boring bar in multiple directions circumferentially on the nylon sleeve, so as to achieve precise positioning of the boring bar in the X-Z plane, which is beneficial to further improve the machining accuracy.

[0102] Here, it should be noted that the positioning holes 2252 on the main board 225 of the fixing mechanism have a certain amount of redundancy relative to the diameter of the boring bar 800. At this time, the fine adjustment is actually to adjust the position of the second through hole 2271 of the nylon sleeve 227 within this redundancy range.

[0103] As a specific example, as Figures 6 - 7 shown, four groups of nylon sleeve tightening screw seat fastening holes 2253 are annularly arranged around the positioning holes 2252 of the main board 225 of the fixing mechanism. The nylon sleeve tightening screw seat 226 is in a convex shape. A nylon sleeve tightening screw connection hole 2263 is horizontally opened on the convex head 2262 of the convex-shaped nylon sleeve tightening screw seat 226, and seat fixing holes 2261 are vertically opened at both ends of the convex-shaped nylon sleeve tightening screw seat 226. Screwing the nylon sleeve tightening screw seat fastening hole 2253 and the seat fixing hole 2261 completes the fixation of the nylon sleeve tightening screw seat 226 on the main board 225 of the fixing mechanism. The nylon sleeve tightening screw 228 is horizontally inserted into the nylon sleeve tightening screw connection hole 2263 and its end abuts against and tightens the nylon sleeve 227.

[0104] Furthermore, the outer circumference of the nylon sleeve 227 is respectively formed with cut surfaces in the up-down, left-right directions, and first bosses 2272 are respectively formed at both ends of the nylon sleeve 227. The adjusting members include four groups. A second boss 2281 is formed at one end of the nylon sleeve tightening screw 228 close to the nylon sleeve 227, and the second boss 2281 is fitted between the two first bosses 2272. The four groups of adjusting members respectively tighten and fix the nylon sleeve 227 on the four cut surfaces of the outer circumference of the nylon sleeve 227. By adjusting the relative positions of the nylon sleeve 227 around the main board 225 of the fixing mechanism in the up-down, left-right directions, the structure is simple and rapid adjustment can be achieved. In addition, the second boss 2281 at the top of the nylon sleeve tightening screw 228 is limited between the two first bosses 2272 at both ends of the nylon sleeve 227, which can ensure that the nylon sleeve 227 will not slip off during the adjustment process or the machining process. In addition, by setting the second boss 2281 at the top of the tightening screw 228, the acting force during adjustment can be evenly dispersed, avoiding damage to the nylon sleeve 227. In addition, an opening groove communicating with the second through hole 2272 can also be formed on the nylon sleeve 227 along the extending direction of the second through hole 2272. By setting the opening groove, it can be applicable to boring bars 800 with different diameters, and the nylon sleeve 227 can be closely attached to the outer circumference of the boring bar 800 through the nylon sleeve tightening screw 228, which is beneficial to improving the machining accuracy.

[0105] Furthermore, as Figure 8As shown, the ear plate assembly fixing device 400 is a fixing bracket, including: a fixing bracket bottom plate 410, two fixing bracket panels 430, multiple sets of tension bolt pairs 441, and multiple jacking bolts 461. Among them, as Figure 2 shown, the fixing bracket bottom plate 410 is arranged on the base 100. The two fixing bracket panels 430 are vertically arranged on the fixing bracket bottom plate 410. The two fixing bracket panels 430 are parallel to each other and define a space therebetween for accommodating the ear plate assembly 1100. Multiple tension bolt holes 440 and jacking bolt holes 460 are respectively formed on the fixing bracket panels 430. Multiple sets of tension bolt pairs 441 pass through the tension bolt holes 440 to connect the two fixing bracket panels 430 to tighten them. Multiple jacking bolts 461 respectively pass through the jacking bolt holes 460 to jack the ear plate assembly 1100 from both sides of the ear plate assembly 1100.

[0106] In addition, a third through hole 431 for passing through the boring bar 800 is formed in the middle of the two fixing bracket panels 430, which is convenient for the boring bar 800 to enter the ear plate assembly fixing device 400 to process the ear plate assembly 1100. Of course, an opening groove can also be formed at the relative position. The present invention does not limit its specific form, as long as it can allow the boring bar 800 to pass through to bore the ear plate assembly clamped therein.

[0107] In addition, a fixing plate reinforcing rib plate 420 can be arranged between the fixing bracket panel 430 and the fixing bracket bottom plate 410 to improve the stability of the ear plate assembly fixing device 400 when being processed.

[0108] Furthermore, the auxiliary device can further include: an ear plate assembly fixing device support plate 300. As Figures 1 - 2 shown, one end of the ear plate assembly fixing device support plate 300 is connected to the fixing bracket panel 430 and the other end is connected to the base 100. Thereby, the stability of the ear plate assembly fixing device can be further improved. As an example, for example, an ear plate assembly fixing device support plate mounting ear plate one 130 and an ear plate assembly fixing device support plate mounting ear plate two 450 are respectively arranged on the top surface of the base 100 and the side surface of the fixing bracket panel 430. Both ends of the ear plate assembly fixing device support plate 300 are respectively connected to the ear plate assembly fixing device support plate mounting ear plate one 130 and the ear plate assembly fixing device support plate mounting ear plate two 450 through bolt pairs. This structure is simple and can be disassembled and replaced.

[0109] Furthermore, as Figure 3As shown in the figure, the base 100 includes: a base body 110 and a boring bar positioning device mounting seat 150. The boring bar positioning device mounting seat 150 is arranged on the base body 110, and a long hole 151 is provided on the boring bar positioning device mounting seat 150. The boring bar positioning device 200 is fixedly arranged on the boring bar positioning device mounting seat 150 in a position-adjustable manner along the long hole 151. Thus, according to specific processing requirements, the specific position of the boring bar positioning device 200 on the boring bar positioning device mounting seat 150 can be adjusted, which can further improve its applicability. As an example, as Figures 4 - 5 shown, guide mechanism fixing grooves 218 are respectively provided at both ends of the bottom plate 211 of the boring bar positioning device 200, and the fixed connection of the boring bar positioning device 200 is completed by screwing the guide mechanism fixing grooves 218 and the long hole 151 on the boring bar positioning device mounting seat 150.

[0110] Furthermore, there are two boring bar positioning device mounting seats 150. Both ends of the boring bar positioning device 200 are respectively arranged on the boring bar positioning device mounting seats 150. A vise through-hole is formed corresponding to the two boring bar positioning device mounting seats 150 for the ear plate assembly fixing device 400,

[0111] The auxiliary device further includes a vise 700. The vise 700 is arranged between the two boring bar positioning device mounting seats 150 and one end passes through the vise through-hole 480 to clamp the bottom edge of the ear plate assembly 1100 exposed from the vise through-hole 480 (as Figures 15 - 16 shown).

[0112] In addition, as a specific example, ear plate assembly fixing device mounting flanges 140 can also be provided on the opposite sides of the boring bar positioning device mounting seat 150. Both ends of the ear plate assembly fixing device 400 are respectively fixedly arranged on the ear plate assembly fixing device mounting flanges 140. In addition, lifting lugs 120 can also be installed on the side surface of the base body 110 for easy hoisting.

[0113] Furthermore, the auxiliary device can further include: a pull plate 600. One end of the pull plate 600 is connected to the boring bar positioning device 200 and the other end is connected to the ear plate assembly fixing device 400. Thus, the overall stability of the auxiliary device is further improved. As an example, pull plate fixing screw holes one 217 can be provided at both ends of the top surface of the guide seat 212 of the boring bar positioning device 200, and pull plate fixing screw holes two 470 can be provided on the top surface of the fixed frame panel 430 of the ear plate assembly fixing device 400. Both ends of the pull plate 600 are respectively screwed to the pull plate fixing screw holes one 217 and the pull plate fixing screw holes two 470 to complete the connection between the boring bar positioning device 200 and the ear plate assembly fixing device 400. This structure is more convenient for disassembly and replacement.
