Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 and 2, an embodiment of the present application provides a bolt dismounting device, which includes a base 1, a transverse driving mechanism 2 provided on the base 1, a longitudinal driving mechanism 3 provided on the transverse driving mechanism 2, a vertical driving mechanism 4 provided on the longitudinal driving mechanism 3, and a bolt dismounting device 5 provided on the vertical driving mechanism 4. The material and shape of the base 1 are not limited, and can be selected according to actual needs, for example, a flat plate structure made of metal material with low cost is suggested to be preferable. Wherein the bolt replacer 5 comprises an electric wrench, a pneumatic wrench, an electric screwdriver or a pneumatic screwdriver.

The transverse driving mechanism 2 can drive the longitudinal driving mechanism 3, the vertical driving mechanism 4 and the bolt replacer 5 to do transverse movement on the base 1. The longitudinal driving mechanism 3 can drive the vertical driving mechanism 4 and the bolt replacer 5 to do longitudinal movement on the base 1. The vertical driving mechanism 4 can drive the bolt replacer 5 to do vertical motion on the base 1. That is, the bolt dismounting device can realize the longitudinal, transverse and vertical movement of the bolt dismounting device 5 through the longitudinal driving mechanism 3, the transverse driving mechanism 2 and the vertical driving mechanism 4, so that the bolt dismounting device 5 reaches the position of the bolt/nut and carries out automatic dismounting on the bolt/nut.

It should be noted that the transverse driving mechanism 2, the longitudinal driving mechanism 3, the vertical driving mechanism 4 and the bolt disassembling and assembling device 5 can be controlled by a controller, and the controller can be a part of the bolt disassembling and assembling device, namely, the bolt disassembling and assembling device comprises a controller connected with the transverse driving mechanism 2, the longitudinal driving mechanism 3, the vertical driving mechanism 4 and the bolt disassembling and assembling device 5. In addition, the controller may also be part of other equipment, such as a controller of an assembly line. The controller includes a programmable logic control unit (such as a PLC or CPU), a memory, and an electronic component connected to the programmable logic control unit, etc., which are well known to those skilled in the art and will not be described in detail herein.

The transverse driving mechanism 2 can be selected as an air cylinder, a hydraulic cylinder or an electric push rod and the like. As shown in fig. 2 and 3, in order to improve the control accuracy of the lateral displacement, the lateral driving mechanism 2 may include a first motor 21 fixedly disposed on the base 1, a first lead screw 22 rotatably disposed on the base 1 and driven by the first motor 21, and a first slider 23 slidably disposed on the base 1. The first slider 23 is intended to carry the longitudinal drive 3 and has an internally threaded hole for cooperation with the first threaded spindle 22. When the first motor 21 rotates forward, the first motor 21 drives the first lead screw 22 to rotate in the first slider 23 and drive the first slider 23 to gradually get away from the first motor 21, and when the first motor 21 rotates backward, the first motor 21 drives the first lead screw 22 to reversely rotate in the first slider 23 and drive the first slider 23 to gradually get close to the first motor 21. In this way, the lateral position of the bolt replacer 5 can be accurately adjusted. Preferably, the first motor 21 is preferably a servo motor in order to further improve the control accuracy of the lateral displacement.

The sliding connection between the first sliding block 23 and the base 1 can be realized by a sliding rail structure. For example, the transverse driving mechanism 2 includes two first blocking plates 24 transversely disposed on the base 1 and clamping the first sliding block 23, one of the contact interfaces between the first blocking plates 24 and the first sliding block 23 is provided with a first sliding slot, and the other one is provided with a protrusion matching with the first groove, so that the first sliding block 23 can only slide stably between the two first blocking plates 24. The slide rail structure can stabilize the movement of the first slide block 23 and improve the stability and reliability of the bolt dismounting device during operation.

First lead screw 22 can rotationally establish on base 1 with the help of two bearing frames, and two bearing frames are fixed to be established on base 1 promptly, and the both ends of first lead screw 22 penetrate the bearing frame respectively to can rotate for base 1 under the support of bearing frame. The bearing seat used in this embodiment can also be replaced by a bearing plate with a shaft hole, and it is continuously ensured that the first threaded spindle 22 can rotate relative to the base 1.

When the second motor 31 rotates forward, the second motor 31 drives the second lead screw 32 to rotate in the second slider 33 and drive the second slider 33 to gradually move away from the second motor 31, and when the second motor 31 rotates backward, the second motor 31 drives the second lead screw 32 to rotate reversely in the second slider 33 and drive the second slider 33 to gradually move closer to the second motor 31. In this way the longitudinal position of the bolt replacer 5 can be accurately adjusted. Preferably, the second electrode is preferably a servomotor, in order to further improve the control accuracy of the longitudinal displacement.

The sliding connection between the second slider 33 and the mounting plate 35 may be realized by a slide rail structure. For example, the longitudinal driving mechanism 3 includes two second blocking plates 34 disposed on the mounting seat along the longitudinal direction and holding the second sliding block 33, one of the contact interfaces between the second blocking plates 34 and the second sliding block 33 is provided with a second sliding slot, and the other one is provided with a second protrusion cooperating with the second sliding slot, so that the second sliding block 33 can only slide between the two second blocking plates 34.

The second lead screw 32 can be rotatably arranged on the mounting plate 35 by means of two bearing seats, namely, the two bearing seats are fixedly arranged on the mounting plate 35, and two ends of the second lead screw 32 respectively penetrate into the bearing seats and can rotate relative to the mounting plate 35 under the support of the bearing seats. The bearing block used in this embodiment can also be replaced by a bearing plate with a shaft hole and continue to ensure that the second threaded spindle 32 can rotate relative to the mounting plate 35.

The vertical driving mechanism 4 can be selected as an air cylinder, an electric push rod or an electro-hydraulic push rod. In the embodiment shown in fig. 1, the vertical driving mechanism 4 is preferably a cylinder, which has the advantages of fast response, less pollution, low cost, etc. compared with an electric push rod or an electro-hydraulic push rod. When supplying air to the cylinder, the cylinder can drive the bolt replacer 5 to move up, and the bolt replacer 5 stops supplying air when reaching the position of the high-position bolt, so that the bolt replacer 5 is aligned with the high-position bolt. When releasing or exhausting the gas in the cylinder, the cylinder can drive the bolt replacer 5 to perform descending motion, and the bolt replacer 5 stops releasing or exhausting when reaching the position of the low-level bolt, so as to be aligned with the low-level bolt.

In the preferred embodiment shown in fig. 5, the connecting part 6 comprises a connecting body 61, a jacking pin 62 and a jacking screw 63. The connecting body 61 includes a first space 611 that accommodates the movable rod portion of the cylinder, the electric push rod, or the electric-hydraulic push rod, a second space 612 that accommodates the body of the bolt replacer 5, and a pin hole 613 that communicates the first space 611 and the second space 612. The knock pin 62 is provided in the pin hole 613 and abuts against the movable rod portion and the body. The side wall of the connecting body 61 is provided with an internal threaded hole, and the jacking screw 63 is screwed into the internal threaded hole of the connecting body 61 and is jacked on the bolt replacer. In the assembling process, the connecting body 61 is firstly buckled or sleeved on the movable rod part of the cylinder, the electric push rod or the electric hydraulic push rod, then the body of the bolt replacer 5 is arranged in the second space 612, then the tightening screw 63 is screwed, and when the body of the bolt replacer 5 is tightened in the second space 612, the tightening screw 63 can also press the jacking pin 62 through the body of the bolt replacer 5, so that the jacking pin 62 directly jacks the cylinder, the electric push rod or the electric hydraulic push rod in the first space 611. The jacking screw 63 is preferably coaxial with the jacking pin 62, so that the jacking screw 63 can better operate the jacking pin 62, and further, the air cylinder, the electric push rod or the electric hydraulic push rod can be more reliably jacked in the first space 611. It should be noted that the connecting part 6 is not limited to the corresponding structure shown in fig. 1, but that other known connecting structures, such as two clips welded together, may be chosen.
