Description

Technical Field

[0001] The utility model belongs to the technical field of bolt protection sleeves, and in particular relates to assembly equipment for screw protection sleeves. Background Art

[0002] Bolt and nut connection is a common connection method. When bolts are used outdoors or in other harsh environments, it is usually necessary to install a protective cover on the outside of the bolt to prevent foreign matter from invading the threaded connection part and to avoid the thread being contaminated or damaged and affecting the connection quality.

[0003] like Fig.11 , which is a schematic diagram of the structure of the nut 4 and the screw 5. The end of the screw 5 away from the nut 4 is provided with a clamping portion 501, which is used to clamp the rubber protective cover 6. The notch 502 is provided in the screw 5 and is hexagonal, so that the worker can use a hexagonal screwdriver to screw the screw 5 onto the nut 4.

[0004] like Fig.12 As shown, it is a schematic diagram of the structure after the screw rod 5 and the nut 4 are screwed together. Fig.13 As shown in FIG. 1 , it is a schematic diagram of the structure in which the protective sleeve 6 is sleeved on the screw rod 5. Fig.14 As shown, after the protective sleeve 6 is assembled, the clamping portion 501 is clamped in the through groove 602 and the clamping groove 603 of the protective sleeve 6. Under the action of the protective sleeve 6, foreign matter is prevented from invading the threaded connection part, thereby preventing the thread from being contaminated or damaged and affecting the connection quality.

[0047] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0048] like Figure 1 The figure is a schematic diagram of the structure of the screw protection sleeve assembly device of the utility model, which is usually used in Fig.12 The end of the screw rod 5 shown is covered with a protective sleeve 6 to prevent foreign matter from invading the threaded connection part and to prevent the thread from being contaminated or damaged and affecting the connection quality. Figure 1 The assembly device for the screw protection sleeve shown includes a base plate 1 , a conveying mechanism 2 and a pressing mechanism 3 .

[0049] The bottom plate 1 is fixed on the assembly machine by screw fastening, and the conveying mechanism 2 is arranged on the bottom plate 1 for conveying the nut 4 locked with the screw 5. The pressing mechanism 3 is arranged on one side of the conveying mechanism 2 for conveying the protective cover 6 and putting it on the end of the screw 5, thereby completing the assembly of the protective cover 6.

[0050] like Figure 2 As shown, it is a schematic diagram of the structure of the conveying mechanism 2, which is arranged on the bottom plate 1 for conveying the nut 4 locked with the screw 5. The conveying mechanism 2 includes a first pad 201, a first support plate 202, a conveying slide rail 203, a conveying slider 204, a first cylinder fixing plate 205, a conveying push cylinder 206, a carrier plate 207, a feeding slide rail 208, a feeding slider 209, a connecting plate 210, a proximity switch 211, a bearing seat 212, a slot 213, a vertical plate 214, a top plate 215, a diagonal brace 216, a guide sleeve 217, a guide column 218, a pressing cylinder 219, a guide plate 220, a pressing block 221, a pressing groove 222 and a first hydraulic buffer 223. There are two first pads 201, which are fixed to the top of the bottom plate 1 by screw fastening. The first pad 201 is used to prop up the carrier plate 207, so as to facilitate the subsequent centering assembly of the screw 5 and the protective sleeve 6.

[0051] The first support plate 202 is fixed on the top of the two first pads 201, the conveying slide rail 203 is fixed on the top of the first support plate 202 by screw fastening, and the conveying slider 204 is slidably installed on the conveying slide rail 203. The carrier plate 207 is fixed on the conveying slider 204, and when the carrier plate 207 moves, it will drive the conveying slider 204 to move synchronously along the conveying slide rail 203, thereby increasing the stability and accuracy of the carrier plate 207 when moving.

[0052] The first cylinder fixing plate 205 is vertically fixed on one side of the first supporting plate 202, the cylinder body of the conveying push cylinder 206 is fixed on the first cylinder fixing plate 205, the piston rod of the conveying push cylinder 206 passes through the first cylinder fixing plate 205 and is connected to the carrier plate 207, and the carrier plate 207 is driven by the conveying push cylinder 206 to move linearly on the base plate 1.

[0053] A first hydraulic buffer 223 is fixed to one side of the first support plate 202 away from the first cylinder fixing plate 205. When the carrier plate 207 moves to the material loading and unloading position, it will contact the first hydraulic buffer 223. The first hydraulic buffer 223 reduces noise and vibration while converting the kinetic energy generated by the moving object into heat energy and releasing it into the atmosphere, thereby achieving a balanced and effective stop of the object during the action.

[0054] The feeding slide rail 208 is fixed to the top of the bottom plate 1 by screw fastening and is parallel to the conveying slide rail 203. The feeding slider 209 is slidably mounted on the feeding slide rail 208. The connecting plate 210 is "L" shaped, with one side fixed to the feeding slider 209 and the other side fixed to the carrier plate 207. When the conveying push cylinder 206 drives the carrier plate 207 to move, the conveying slider 204 will slide along the conveying slide rail 203, and at the same time, the feeding slider 209 will slide along the feeding slide rail 208 synchronously. This improves the stability of the carrier plate 207 when it moves, and prevents it from deviating left and right, which affects the subsequent assembly operation.

[0055] The bearing seat 212 is fixed on the top of the carrier plate 207, and the slot 213 is provided on the top of the bearing seat 212. A structure matching the outer surface of the nut 4 is provided in the slot 213, and the nut 4 with the screw 5 locked is placed on the slot 213. The proximity switch 211 is fixed on the carrier plate 207 and is located on one side of the bearing seat 212. When the nut 4 with the screw 5 locked is placed, the screw 5 will pass through the nut 4 for a distance because the length of the screw 5 is greater than the length of the nut 4. The proximity switch 211 is used to monitor the length of the screw 5 in real time to avoid deviation in the placement position of the nut 4, thereby affecting the assembly accuracy of the protective cover 6.

[0056] The vertical plate 214 is vertically fixed on the top of the carrier plate 207, and the top plate 215 is fixed on the top of the vertical plate 214 and is parallel to the carrier plate 207. An oblique brace 216 is provided between the top plate 215 and the vertical plate 214 to improve the structural strength between the top plate 215 and the vertical plate 214 and prevent the top plate 215 from bending downward when the nut 4 is pressed.

[0057] The cylinder body of the pressing cylinder 219 is fixed on the top plate 215, and the piston rod of the pressing cylinder 219 passes through the top plate 215 and is connected to the pressing block 221. The pressing cylinder 219 drives the pressing block 221 to descend to press the nut 4 locked with the screw 5, so as to avoid the nut 4 from being overturned when the protective sleeve 6 is subsequently assembled. The bottom of the pressing block 221 is provided with a pressing groove 222 that matches the outer surface of the nut 4. Therefore, before assembly, the pressing cylinder 219 will drive the pressing block 221 to descend until the nut 4 is pressed between the clamping groove 213 and the pressing groove 222.

[0058] In order to improve the position accuracy of the pressing block 221 when it descends and avoid the defect of the pressing block 221 not being properly installed due to the left-right deviation when it descends, a matching guide sleeve 217 and a guide column 218 are provided on the top plate 215. The guide column 218 and the pressing block 221 are connected through the guide plate 220. When the pressing cylinder 219 drives the pressing block 221 to descend, it will drive the guide column 218 to descend synchronously in the guide sleeve 217, so as to realize the positioning and guiding of the pressing block 221.

[0059] like Figure 3 , 4The figure is a schematic diagram of the structure of the press-fitting mechanism 3, which is used to automatically press-fit the protective cover 6 on one end of the screw 5 to prevent foreign matter from invading the threaded connection parts and to prevent the thread from being contaminated or damaged and affecting the connection quality. The press-fitting mechanism 3 includes a second pad 301, a second support plate 302, a press-fitting slide rail 303, a press-fitting slider 304, a moving plate 305, a second cylinder fixing plate 306, a press-fitting push cylinder 307, a mounting plate 308, a second oil pressure buffer 309, a loading cylinder 310, a synchronous plate 311, a flip assembly, an insertion plate 322, a mounting head 323, a slot 324, a plug-in column 325 and a guide portion 326.

[0060] There are two second pads 301 fixed on the top of the bottom plate 1, and the second support plate 302 is fixed on the top of the second pad 301. The second pad 301 is provided to support the flip assembly, ensuring that the protective cover 6 is coaxially arranged with the screw 5, and facilitating the subsequent assembly of the protective cover 6. The press-fitting slide rail 303 is fixed on the top of the second support plate 302 by screw fastening, and the press-fitting slider 304 is slidably installed on the press-fitting slide rail 303. The press-fitting slide rail 303 has the same function as the conveying slide rail 203, which will not be described in detail here.

[0061] The second cylinder fixing plate 306 is vertically fixed on one side of the top of the second support plate 302, the movable plate 305 is fixed on the press-fitting slider 304, the cylinder body of the press-fitting pushing cylinder 307 is fixed on the second cylinder fixing plate 306, and the piston rod of the press-fitting pushing cylinder 307 passes through the second cylinder fixing plate 306 and is connected to the movable plate 305, which is used to drive the movable plate 305 to move forward to approach the bearing seat 212, and then press the protective cover 6 on the end of the screw 5.

[0062] The mounting plate 308 is fixed to the other side of the top of the second support plate 302, and a second hydraulic buffer 309 is fixed to the mounting plate 308 to match the moving plate 305. The second hydraulic buffer 309 has the same function as the first hydraulic buffer 223, which will not be described in detail here. The flip assembly is fixed to the top of the moving plate 305, and the mounting head 323 is fixed to the flip assembly to carry the protective cover 6 to be assembled.

[0063] The flip assembly is connected to the moving plate 305 via the synchronous plate 311, the loading cylinder 310 is fixed on the second cylinder fixing plate 306 and connected to the synchronous plate 311, and the loading cylinder 310 is arranged in parallel with the press-fitting pushing cylinder 307. When the protective sleeve 6 is actually assembled, the loading cylinder 310 and the press-fitting pushing cylinder 307 work simultaneously, and jointly push the moving plate 305 and the flip assembly forward, ensuring that sufficient thrust is applied to the mounting head 323, so that the protective sleeve 6 is sleeved on the end of the screw 5.

[0064] like Figure 5-8, which is a schematic diagram of the structure of the flip assembly, and the flip assembly drives the mounting head 323 to switch between the horizontal and vertical states, thereby completing the installation and assembly of the protective cover 6. The flip assembly includes a linear cylinder 312, a mounting seat 313, a rack 314, a flip plate 315, a transfer block 316, a convex tooth 317, a first limiting screw 318, a first limiting nut 319, a second limiting screw 320 and a second limiting nut 321. The cylinder body of the linear cylinder 312 is fixed to the side of the synchronization plate 311 away from the second cylinder fixing plate 306, and the mounting seat 313 is fixed to the cylinder body of the linear cylinder 312.

[0065] A switching block 316 is integrally connected to one side of the flip plate 315 close to the linear cylinder 312 . The switching block 316 and the flip plate 315 are pivotally connected to each other, and the flip plate 315 is switched between horizontal and vertical states under the drive of the linear cylinder 312 .

[0066] like Figure 8 As shown, a rack 314 is connected to the piston rod of the linear cylinder 312, and a convex tooth 317 meshing with the rack 314 is provided on one side of the adapter block 316. Through the cooperation of the linear cylinder 312, the rack 314 and the convex tooth 317, the switching of the flip plate 315 between the horizontal and vertical states is realized.

[0067] Two groups of threaded holes are provided on the side wall of the adapter block 316, one group of threaded holes is arranged horizontally, and the other group of threaded holes is arranged vertically. The first limit screw 318 is screwed into the vertically arranged threaded hole, and the second limit screw 320 is screwed into the horizontally arranged threaded hole.

[0072] The assembly process of the assembly equipment for the screw protection sleeve of the utility model is as follows:

[0073] First, place the nut 4 with the screw 5 in the slot 213, and the pressing cylinder 219 drives the pressing block 221 to descend until the nut 4 with the screw 5 is pressed between the slot 213 and the pressing slot 222, so as to avoid turning over the nut 4 when the protective sleeve 6 is assembled later;

[0074] The operator inserts the protective cover 6 into the mounting head 323, and the flip assembly flips it to a vertical state. The loading cylinder 310 and the press-fitting push cylinder 307 work simultaneously to jointly push the moving plate 305 and the flip assembly forward, ensuring that sufficient thrust is applied to the mounting head 323, thereby putting the protective cover 6 on the end of the screw 5.
