Description

Technical Field

[0001] This invention belongs to the field of mechanical equipment installation technology, and more specifically, relates to an auxiliary positioning mechanism for mechanical equipment assembly. Background Technology

[0002] Industrial automation is a trend and technology that utilizes automatic control, automatic adjustment devices, and other information technology to replace manual operation of machines and machine systems in processing and production. It is changing our production methods, improving production efficiency, reducing costs, ensuring product quality, and bringing better hope for human progress and development. Industrial automation can be divided into two stages according to its development: Semi-automation, where some parts use automatic control and automatic devices, while other parts are still operated manually; and Full automation, where all processes in the production process, including feeding, unloading, and loading / unloading, do not require direct human operation (humans only indirectly supervise and monitor machine operation), and the machines continuously and repeatedly produce one or a batch of products automatically.

[0003] In industrial automated production, positioning is a core component, directly affecting the accuracy and efficiency of assembly. Currently, positioning mechanisms are readily available on the market, but the applicant has found that high-precision positioning mechanisms are often quite expensive. This not only increases the cost of industrial automated assembly, but also makes the subsequent maintenance of these high-precision positioning mechanisms a significant economic burden. Therefore, finding a way to achieve positioning functionality through the simplest possible mechanism has high practical value. Summary of the Invention

[0004] In order to address the problems existing in the prior art, the present invention aims to provide an auxiliary positioning mechanism for assembling mechanical equipment, which can achieve a simple structure that is easy to manufacture, while providing precise positioning and stable support during the installation process, thereby improving the accuracy and reliability of the installation.

[0005] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

A double-speed chain conveyor, a limiting module, a positioning module, and a straightening module are arranged on the support frame. The double-speed chain conveyor passes through the assembly area, the limiting module and the positioning module are located within the assembly area, and the straightening module is located on one side of the assembly area. A tooling plate for fixing the mechanical equipment to be assembled is provided on the double-speed chain conveyor.

[0007] Furthermore, the double-speed chain conveyor line includes an input double-speed chain line disposed above the support frame and a return double-speed chain line disposed below the support frame.

[0010] Furthermore, the alignment module includes a fixed plate, on which an alignment cylinder is disposed, and at the front end of the piston rod of the alignment cylinder is an alignment component.

[0011] Furthermore, the alignment component is disposed at the front end of the piston rod of the alignment cylinder via a third connecting plate. The two sides of the third connecting plate are respectively connected to a set of slide rails, and the third connecting plate can move back and forth along the slide rails by being driven by the alignment cylinder.

[0012] Furthermore, the alignment component includes a connecting seat on which an alignment wheel is rotatable.

[0013] Furthermore, the positioning module includes a second connecting plate, on which a lifting and positioning cylinder is provided. The upper end of the piston rod of the lifting and positioning cylinder is provided with a positioning plate, and the positioning plate is provided with a positioning pin.

[0014] Furthermore, the lower end of the positioning plate is provided with at least two sets of guide shafts, each of which passes through the second connecting plate via a straight-line bearing.

[0015] Furthermore, the support frame is also provided with a blocking module, which includes a fourth connecting plate and a lifting blocking cylinder. The piston rod of the lifting blocking cylinder is provided with a blocking block at its front end.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. The invention enables the automatic transport of the mechanical equipment to be assembled to the assembly area, and while confining the mechanical equipment to be assembled within the assembly area, it also achieves the alignment of the mechanical equipment to be assembled, thereby enabling the subsequent precise positioning of the mechanical equipment to be assembled, thus ensuring the accurate and reliable assembly of the mechanical equipment and thus guaranteeing the quality of the mechanical equipment.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] See Figure 1 As shown, a mechanical equipment assembly auxiliary positioning mechanism includes a support frame 1, on which an assembly area 101 is formed. A double-speed chain conveyor 3, a limiting module 4, a positioning module 5, and a straightening module 6 are disposed on the support frame 1. The double-speed chain conveyor 3 passes through the assembly area 101. The limiting module 4 and the positioning module 5 are located within the assembly area 101. The straightening module 6 is disposed on one side of the assembly area 101. A tooling plate 2 for fixing the mechanical equipment to be assembled is disposed on the double-speed chain conveyor 3. The tooling plates 2 are placed on the double-speed chain conveyor 3, and the tooling plates 2 can pass through the assembly area 101 by being driven by the double-speed chain conveyor 3. In this embodiment, in order to prevent the tooling plates 2 from slipping off the support frame 1 from both sides of the double-speed chain conveyor 3 during the conveying process, causing damage to the mechanical equipment to be assembled fixed on the tooling plates 2, limit plates 102 are provided on the support frame 1 along both sides of the double-speed chain conveyor 3. The limit plates 102 are higher than the double-speed chain conveyor 3, but lower than the upper surface of the tooling plates 2.

[0031] For further details, please refer to [link / reference]. Figure 1 As shown, in this embodiment, the double-speed chain conveyor line 3 includes an input double-speed chain line 301 disposed above the support frame 1 and a return double-speed chain line 302 disposed below the support frame 1. During operation, the tooling plate 2, on which the mechanical equipment to be assembled is fixed, is sent to the assembly area 101 for assembly via the input double-speed chain line 301. After assembly, it is conveyed to other processes. After all processes are completed, it is returned to the unloading position of the mechanical equipment via the return double-speed chain line 302.

[0032] Further, see Figure 2 As shown in the figure, in this embodiment, four sets of positioning holes 201 are provided on the lower end surface of the tooling plate 2, but it is not limited to four sets, and other sets can be provided as long as the requirements are met; the upper end of the tooling plate 2 can be provided with a corresponding fixing structure according to the model, type, etc. of the mechanical equipment to be fixed, so as to facilitate the fixing of the mechanical equipment; it should be noted that the specific structure of the upper end of the tooling plate 2 is not shown in the figure.

[0033] Further, see Figure 3As shown, in this embodiment, the limiting module 4 includes a first connecting plate 401, which is fixed on the support frame 1. A vertically upward lifting limiting cylinder 402 is provided on the first connecting plate 401, and a rotatable roller 403 is provided at the front end of the piston rod of the lifting limiting cylinder 402. During operation, the roller 403 is driven by the lifting limiting cylinder 402 to move up and down, thereby blocking the tooling plate 2 and restricting the tooling plate 2, on which the mechanical equipment to be assembled is fixed, within the assembly area 101.

[0034] Further, see Figure 5 As shown, in this embodiment, the alignment module 6 includes a fixed plate 601, which is fixed to the support frame 1 by a corresponding support base. An alignment cylinder 602 is provided on the fixed plate 601, which is also fixed to the fixed plate 601 by a corresponding support base. When the fixed plate 601 is fixed to the support frame 1 by a corresponding support base, the alignment cylinder 602 is at a 45° angle to the direction of the double-speed chain conveyor line 3. An alignment component 603 is provided at the front end of the piston rod of the alignment cylinder 602. The alignment component 603 can move back and forth by being driven by the alignment cylinder 602. During operation, when the tooling plate 2 is confined within the assembly area 101, the tooling plate 2 may deviate to the side during the conveying process. At this time, the alignment cylinder 602 is activated, driving the alignment component 603 to push the tooling plate 2, aligning and confining the tooling plate 2 to prevent it from deviating to the side again.

[0035] In this embodiment, to prevent the alignment cylinder 602 from driving the alignment component 603 to deviate, see below. Figure 5 As shown, the alignment component 603 is disposed at the front end of the piston rod of the alignment cylinder 602 via a third connecting plate 604. Both sides of the third connecting plate 604 are respectively connected to a set of slide rails 605. The slide rails 605 are fixed on the fixed plate 601, and the direction of the slide rails 605 is parallel to the running direction of the piston rod of the alignment cylinder 602. The third connecting plate 604 can move back and forth along the slide rails 605 driven by the alignment cylinder 602, thereby driving the alignment component 603 to move back and forth.

[0036] Furthermore, in this embodiment, see also... Figure 5As shown, the straightening assembly 603 includes a connecting seat 6031, which is fixed to the third connecting plate 604 by a connecting block 606. A pair of straightening wheels 6032 are provided on the connecting seat 6031, and both wheels are rotatably mounted on the connecting seat 6031. During operation, the pair of straightening wheels 6032 push against the two right-angled sides of the tooling plate 2, thereby straightening the tooling plate 2. Specifically, as shown... Figure 1 As shown.

[0037] Further, see Figure 4 As shown, in this embodiment, the positioning module 5 includes a second connecting plate 501, which is fixed on the support frame 1. A vertically upward lifting and positioning cylinder 502 is mounted on the second connecting plate 501. A positioning plate 503 is mounted on the upper end of the piston rod of the lifting and positioning cylinder 502. The positioning plate 503 can move up and down by the drive of the lifting and positioning cylinder 502. Positioning pins 504, corresponding one-to-one with the positioning holes 201, are mounted on the positioning plate 503. During operation, when the positioning module 5 is aligned... After module 6 aligns the tooling plate 2, the lifting and positioning cylinder 502 drives the positioning plate 503 to move upward, thereby lifting the tooling plate 2 from the double-speed chain conveyor line 3. This lifts the mechanical equipment to be assembled, which is fixed on the tooling plate 2, to a set height for easy assembly. At this time, the positioning pin 504 is inserted into the corresponding positioning hole 201 to position the tooling plate 2, preventing the tooling plate 2 from shifting during the assembly process, which would affect the assembly accuracy and quality of the mechanical equipment.

[0038] In this embodiment, to prevent the positioning pin 504 from failing to penetrate the corresponding positioning hole 201 during the upward movement of the positioning plate 503 driven by the lifting and positioning cylinder 502, thus affecting the subsequent assembly of the mechanical equipment, see below. Figure 4 As shown, the lower end of the positioning plate 503 is provided with four sets of guide shafts 505. All the guide shafts 505 pass through the second connecting plate 501 through a straight line bearing 506. The number of sets of guide shafts 505 is only one embodiment and is not intended to limit the scope of this application. In actual installation, more or fewer sets can be set, as long as the requirements are met.

[0039] Further, see Figure 1As shown, in this embodiment, a blocking module 7 is also provided on the support frame 1. The blocking module 7 is located upstream of the assembly area 101. The blocking module 7 enables the tooling plates 2 to carry the mechanical equipment to be assembled into the assembly area 101 sequentially for assembly, thereby effectively avoiding mutual interference between the tooling plates 2 and affecting the assembly of the mechanical equipment; and in this embodiment, see Figure 6 As shown, the blocking module 7 includes a fourth connecting plate 701, which is fixed on the support frame 1. A vertically upward lifting blocking cylinder 702 is provided on the fourth connecting plate 701. A blocking block 703 is provided at the front end of the piston rod of the lifting blocking cylinder 702. The blocking block 703 can be moved up and down by the driving of the lifting blocking cylinder 702, thereby blocking the tooling plate 2 through the blocking block 703.

[0040] The working principle of this invention is as follows:

[0041] In use, first connect this mechanism to the automated assembly line, then select the corresponding tooling plate 2 according to the model of the mechanical equipment to be assembled; then fix the mechanical equipment to be assembled onto the corresponding tooling plate 2 in sequence, and place it on the input speed-multiplying chain line 301. At this time, the tooling plate 2 with the mechanical equipment to be assembled fixed on it flows towards the assembly area 101. During the process of the tooling plate 2 flowing towards the assembly area 101, when a set of tooling plates 2 passes through the blocking module 7, the lifting blocking cylinder 702 in the blocking module 7 immediately extends the piston rod to drive the blocking block 703 to move upward, blocking the subsequent tooling plate 2, preventing two or more sets of tooling plates 2 from passing through and affecting the subsequent assembly operation; while the tooling plate 2 passing through the blocking module 7... The tooling plate 2 continues to flow towards the assembly area 101 until it enters the assembly area 101 and is blocked by the limiting module 4. Then, the piston rod of the straightening cylinder 602 extends to drive the straightening component 603 to move towards the tooling plate 2. After the tooling plate 2 is straightened, the piston rod of the lifting and positioning cylinder 502 extends to drive the positioning plate 503 to rise. The positioning pin 504 passes through the positioning hole 201 at the front end. When the upper end face of the positioning plate 503 is not in contact with the lower end face of the tooling plate 2, the piston rod of the straightening cylinder 602 retracts to drive the straightening component 603 to reset. The lifting and positioning cylinder 502 continues without stopping until the tooling plate 2 is lifted to the set height by the positioning plate 503. Then, the automated assembly line begins to assemble the mechanical equipment.

[0042] After the mechanical equipment is assembled, the piston rod of the lifting and positioning cylinder 502 retracts, driving the positioning plate 503 to descend and reset. At this time, the tooling plate 2 descends synchronously with the positioning plate 503 under the action of gravity until the tooling plate 2 is placed back onto the input double-speed chain 301. Then, the piston rod of the lifting and limiting cylinder 402 retracts, driving the roller 403 to descend and releasing the tooling plate 2 in the assembly area 101. At this time, the tooling plate 2 is transported to the next process under the drive of the input double-speed chain 301, and after completing all processes, it returns to the previous process via the return double-speed chain 302. The material flows to the unloading position; when the tooling plate 2 in the assembly area 101 has completely flowed out of the assembly area 101, the piston rod of the lifting and positioning cylinder 502 extends and drives the positioning plate 503 to reset to the blocking height. At the same time, the piston rod of the lifting and blocking cylinder 702 retracts and drives the blocking block 703 to descend, releasing the next set of tooling plates 2. Then, the piston rod of the lifting and blocking cylinder 702 extends and drives the blocking block 703 to move upward, continuing to block the subsequent tooling plates 2. The mechanism repeats the above actions, which will not be elaborated here, thereby realizing the continuous assembly operation of the mechanical equipment.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
