DETAILED DESCRIPTION

[0038] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0040] Example 1

[0041] In order to change the current situation that the existing bolt tightening equipment is not provided with a feeding mechanism, which makes it inconvenient for the tightening equipment to take the bolts to complete the assembly of the track plate and the chain link, the present embodiment provides a new tightening equipment, which can continuously realize the feeding of bolts, so that the assembly of the track plate and the chain link can be completed by using the bolts through the tightening equipment.

[0042] like Figure 1-4 As shown, the new tightening device includes a conveyor 1, a bracket 2, a top frame 5, a lifting mechanism 6, a vertical plate 7, and a tightening mechanism 4. The conveyor 1 can be set as a chain plate conveyor or a belt conveyor. In short, it must be able to realize the conveying of crawler components. The bracket 2 is arranged on the side of the conveyor 1, and the top frame 5 is arranged above the bracket 2. In addition, the lifting mechanism 6 is installed on the side of the top frame 5, and its height can be adjusted according to needs. The vertical plate 7 is installed on the side of the lifting mechanism 6, and can be moved on the horizontal plane according to needs. At the same time, the tightening mechanism 4 is installed on the side of the vertical plate 7 away from the lifting mechanism 6. Therefore, under the cooperation of the vertical plate 7 and the lifting mechanism 6, the tightening mechanism 4 can move in the space, which provides convenience for completing the tightening of the bolts. The tightening mechanism 4 is located directly above the conveyor 1. Therefore, under the premise that the tightening mechanism 4 can be adjusted, it provides support for completing the assembly of the crawler. In order to facilitate adding bolts to the tightening mechanism 4 and force the bolts to be installed on the track through the tightening mechanism 4, a feeding mechanism 3 is arranged on the side of the tightening mechanism 4, and the bottom of the feeding mechanism 3 is arranged adjacent to the bottom of the tightening mechanism 4, and the tightening mechanism 4 can move relative to the feeding mechanism 3. When multiple bolts are arranged in an orderly manner on the feeding mechanism 3, the bolts can be removed from the feeding mechanism 3 through the cooperation of the tightening mechanism 4 and the feeding mechanism 3. In addition, a control box 21 is arranged on the side of the bracket 2. The control box 21 is a prior art, which at least includes a controller, a relay, a contactor, etc., so that the control box 21 can control the operation of various components to achieve the installation of bolts.

[0043] like Fig. 9 As shown, in order to install the bolts on the crawler by the tightening mechanism 4 to realize the assembly of the crawler, the tightening mechanism 4 includes a third telescopic cylinder 43, a group of second connecting mechanisms 44, two groups of first connecting mechanisms 42 and four motors 41. The motor 41 can be set as a pneumatic motor or an electric motor. The four motors 41 are distributed at the end corners of the same rectangle, and a tightening sleeve is set at the lower end. The shape of the inner space of the tightening sleeve is adapted to the polygonal top shape of the bolt. Therefore, the tightening sleeve can be sleeved on the top of the bolt and control the rotation of the bolt. In order to stably connect the bolt with the tightening sleeve so that the bolt can provide support as the tightening sleeve moves up and down, a magnet can be set on the inner side of the tightening sleeve, or a rubber layer can be set on the side wall of the tightening sleeve. Under the action of the magnet or the rubber layer, the gravity of the bolt can be overcome to realize the stable connection between the bolt and the tightening sleeve. In order to enable the tightening of the bolts through the operation of the motor 41, a reducer is also arranged between the motor 41 and the tightening sleeve. In addition, a torque sensor, an angle sensor, a control system (including a microprocessor, etc.) can also be arranged. In short, in order to realize the installation of the bolts, in actual production, suitable accessories are selected according to needs to assist the motor 41 and the tightening sleeve.

[0044] like Fig.11As shown, in order to adjust the position of the motor 41 according to the needs and adapt it to different crawlers, the two groups of motors 41 are respectively installed on the two groups of first connecting mechanisms 42, and the first connecting mechanism 42 includes an adjusting screw 423 and two supporting plates 421. The two supporting plates 421 are symmetrically arranged and respectively connected to the two motors 41 of the same group. In order to stably connect the two supporting plates 421, a plug rod 422 is fixedly arranged on one supporting plate 421, and a through hole 424 is arranged on the other supporting plate 421. The plug rod 422 penetrates the through hole 424, and at this time, the two supporting plates 421 are stably and movably connected. One end of the adjusting screw 423 is inserted into a supporting plate 421 through a bearing connection, and the other end is threaded through the threaded connecting hole 425 of the other supporting plate 421. Therefore, by rotating the adjusting screw 423, the relative movement of the two supporting plates 421 can be controlled, and the motor 41 can be driven to move, thereby realizing the adjustment of the position of the motor 41.

[0045] like Fig.10 As shown, in order to control the movement of the two groups of motors 41 and adjust the distance between the two groups of motors 41, the second connecting mechanism 44 includes a gear 442, two racks 443 and two split plates 441. The two split plates 441 are both set to an L-shaped structure and are symmetrical about the center. In addition, the two groups of first connecting mechanisms 42 are respectively connected to the two split plates 441, and the two racks 443 are respectively installed on the horizontal sections of the two split plates 441. The gear 442 is located between the horizontal sections of the two split plates 441 and is meshed and connected with the two racks 443. Therefore, when a split plate 441 moves, the other split plate 441 moves at the same time, thereby achieving the adjustment of the distance between the two groups of motors 41. In order to control the movement of the two split plates 441, a third telescopic cylinder 43 is also provided on the side of the second connecting mechanism 44. The telescopic end of the third telescopic cylinder 43 is connected to a split plate 441. Therefore, the relative movement of the two groups of motors 41 can be controlled by the operation of the third telescopic cylinder 43.

[0046] like Figure 8 As shown, in order to achieve stable installation of the tightening mechanism 4 and to facilitate adjustment of the positions of the two motors 41 according to needs, two clamping plates 71 are fixedly arranged on the side wall of the vertical plate 7, and a clamping slot 444 is arranged on the side of the two split plates 441. The clamping plates 71 penetrate the clamping slot 444, so that the two split plates 441 are stably and movably installed on the vertical plate 7, and the central axis of the gear 442 is connected to the vertical plate 7, so that the two split plates 441 can be adjusted by rotating the gear 442. In addition, the third telescopic cylinder 43 is installed on the vertical plate 7, and the telescopic end is connected to a split plate 441.

[0047] like Figure 5 , Figure 7As shown, in order to control the lifting and lowering of the motor 41 and the tightening sleeve, a plurality of strip holes 51 of different widths are provided on the top frame 5. The lifting mechanism 6 includes a first telescopic cylinder 61, a support plate 65 and two snap plates 62. The first telescopic cylinder 61 is connected and arranged on the side of the support plate 65, and the first telescopic cylinder 61 and the support plate 65 are distributed on both sides of the top frame 5. At the same time, the first telescopic cylinder 61 is fixedly connected to the top frame 5. Therefore, the lifting and lowering of the support plate 65 is controlled under the action of the first telescopic cylinder 61. In order to make the support plate 65 movable and stably connected relative to the top frame 5, a snap groove 63 is provided on the side of the support plate 65 adjacent to the first telescopic cylinder 61, and the snap plate 62 is arranged through the snap groove 63 and is fixedly installed on the top frame 5. Therefore, the support plate 65 is stably installed under the cooperation of the snap plate 62 and the snap groove 63.

[0048] like Figure 7 , Figure 8 As shown, a connecting pipe 64 is fixedly installed at the end corner of the support plate 65, and the connecting pipe 64 is set through the bar hole 51. A limiting plate 73 is fixedly installed at the end corner of the vertical plate 7, and the limiting plate 73 is set through the connecting pipe 64, so that the vertical plate 7 and the support plate 65 are stably and movably connected. A second telescopic cylinder 74 is set on the side of the vertical plate 7, and the second telescopic cylinder 74 is set through the bar hole 51. Therefore, when the second telescopic cylinder 74 is working, the vertical plate 7 can move in the horizontal direction. In order to make the second telescopic cylinder 74 work stably, a connecting pipe 72 is fixedly installed at the end of the second telescopic cylinder 74, and a fixing rod 75 is set through the connecting pipe 72. End frames 76 are set at both ends of the fixing rod 75, and the end frames 76 are connected to the top frame 5. Therefore, when the second telescopic cylinder 74 is lifted and lowered, the second telescopic cylinder 74 is stably installed.

[0049] like Figure 12-16 As shown, in order to realize the continuous feeding of bolts, the feeding mechanism 3 includes two sets of support frames 33 and four sets of guide frames 32. The guide frames 32 include guide rails 321, shields 322 and sleeves 323. The guide rails 321 are set as L-shaped structures. The shields 322 are installed on the guide rails 321, and the bottom of the shields 322 is not directly opposite to the bottom of the guide rails 321. Therefore, when the bolts pass through the guide rails 321 and are placed in order, the bolts can be stably placed relative to the guide rails 321 under the obstruction of the shields 322, and can move along the length direction of the guide rails 321 under the action of gravity until the bolts move to the bottom of the guide rails 321. Because the bottom of the guide rails 321 is not blocked by the shields 322, the top of the bolts moved to the bottom of the guide rails 321 can be inserted into the tightening sleeve. The sleeve 323 is installed on the shield 322 and sleeved on the end of the support frame 33. In addition, a limit bolt is threaded through the sleeve 323, and the limit bolt can press the support frame 33 to stably connect the support frame 33 to the guide frame 32. The bottom of the support frame 33 is connected to the top frame 5, and a plurality of bolts 31 are arranged in an orderly manner on the guide frame 32.

[0050] In order to enable the top of the bolt located at the bottom of the guide rail 321 to be inserted into the tightening sleeve, the feeding mechanism 3 also includes two sets of lifting frames 34, and the two sets of lifting frames 34 are matched one by one with the two sets of support frames 33; the lifting frame 34 includes a transverse tube 342, an end plate 343 and an L-shaped plate, the L-shaped plate is vertically installed on the transverse tube 342, and a clamping groove 341 is provided at the end. The clamping plate 331 installed on the support frame 33 passes through the clamping groove 341. Therefore, the transverse tube 342 is stably and movably installed on the support frame 33, and a fourth telescopic cylinder is provided on the L-shaped plate. The top of the fourth telescopic cylinder is connected to the support frame 33. Under the action of the fourth telescopic cylinder, the L-shaped plate and the transverse tube 342 can be controlled to rise and fall synchronously. The ends of the two end plates 343 that are close to each other are inserted into the transverse tube 342, and the ends that are far from each other are fixedly provided with a push rod 344. During the process of the transverse tube 342 rising and falling, the push rod 344 rises and falls synchronously. Therefore, when the push rod 344 rises, the bolt located at the bottom of the guide rail 321 can be controlled to rise, even if the top of the bolt protrudes from the top of other bolts. When the bolt rises, the vertical plate 7 can be controlled to move under the action of the second telescopic cylinder 74, so that the tightening sleeve is directly opposite to the bolt, and then the first telescopic cylinder 61 controls the tightening sleeve to descend, so that the tightening sleeve is sleeved on the top of the bolt, so that the bolt is connected to the tightening sleeve. After that, the bolt moves with the tightening sleeve and can be tightened in the track under the action of the motor 41.

[0051] Example 2

[0052] like Figure 6 As shown, on the basis of Example 1, in order to be able to adjust the position of the motor 41 and the tightening sleeve according to needs to make it compatible with the conveyor 1, the bracket 2 includes a top frame 23 and a bottom frame 22 which are parallel to each other, and an outer tube 24 and an inner tube 25 are fixedly arranged at the end corners of the top frame 23 and the bottom frame 22 close to each other on the side, and the end of the inner tube 25 is inserted into the outer tube 24. Therefore, the top frame 23 and the bottom frame 22 are stably and movably connected. In addition, a threaded hole 27 is arranged on the top frame 23, and a threaded column 26 is arranged on the bottom frame 22. The threaded column 26 is threadedly inserted into the threaded hole 27. The relative movement of the top frame 23 and the bottom frame 22 can be adjusted by rotating the threaded column 26, and the relatively moving top frame 23 and bottom frame 22 can be kept relatively still.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
