Description

Technical Field

[0001] This utility model relates to the field of automated conveyor technology, and in particular to a chain conveyor with precise pitch. Background Technology

[0002] A fixed-pitch chain line mainly refers to a linear structure that uses a chain as a transmission or conveying carrier, and the pitch of the chain can be controlled. The chain pitch refers to the distance between the centers of two adjacent pins of the chain. A fixed pitch means that the error of this distance is controlled within a very small range.

[0003] Fixed-pitch chain conveyors enable precise material transport. For example, in an electronics assembly line, when tiny electronic components need to be moved from one workstation to the next, a precise-pitch chain conveyor ensures that each component is accurately transported to a fixed position.

[0004] However, when the chain needs to be repaired, multiple steps between the chain and the pallet must first be removed using tools to separate the pallet from the chain before repairing the chain. This makes it inconvenient to install and remove the pallet from the chain.

[0005] Therefore, it is necessary to provide a chain line with precise pitch to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a chain line with precise pitch, which solves the problem of inconvenient quick installation and disassembly between the pallet and the chain.

[0007] To solve the above-mentioned technical problems, this utility model provides a chain line with precise pitch, comprising:

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First embodiment:

[0027] Please refer to the following: Figure 1-3 This utility model provides a chain line with precise pitch, comprising:

[0028] Ontology 1;

[0029] Mounting bracket 2 is set on the surface of the main body 1. The mounting bracket 2 has a positioning groove 3 inside. A positioning block 4 is slidably connected inside the positioning groove 3. A rotating hole 5 is opened inside the positioning block 4. A rotating rod 6 is rotatably connected inside the rotating hole 5. Two rotating rods 9 are fixedly connected to one end of the rotating rod 6.

[0030] The movable groove 7 is located inside the positioning block 4, and the bottom and top of the movable groove 7 are provided with rotating grooves 8.

[0031] Limiting groove 10 is located inside positioning block 4, and limiting sleeve 11 is provided inside limiting groove 10.

[0032] The movable groove 7 is located inside the positioning block 4. When the two rotating rods 9 rotate to one side and enter the movable groove 7, the positioning block 4 can move to one side and separate from the positioning groove 3.

[0033] The two rotating rods 9 are slidably connected to the interior of the two rotating grooves 8.

[0034] The limiting sleeve 11 is made of rubber and is fixedly connected to the surface of the rotating rod 6 to increase the friction of the rotating rod 6, thereby increasing the stability of the rotating rod 6.

[0035] Both the main body 1 and the mounting bracket 2 have positioning grooves 3 inside that are adapted to the positioning block 4.

[0036] After the positioning block 4 is inserted into the positioning groove 3, the mounting bracket 2 and the main body 1 are positioned to limit the movement.

[0037] Both the positioning block 4 and the mounting bracket 2 have rotating grooves 8 inside.

[0038] The rotating groove 8 is used to limit the distance between the mounting bracket 2 and the positioning block 4 after the two rotating rods 9 enter the interior of the rotating groove 8 when they rotate to one side, so that the positioning block 4 cannot move and separate to one side.

[0039] In this embodiment, when the main body 1 needs to be repaired, the rotating rod 6 is rotated to one side, which drives the two rotating rods 9 to rotate to one side. After rotating to one side inside the rotating groove 8 and entering the moving groove 7, the positioning block 4 is pulled to one side. After separating inside the positioning groove 3, the mounting bracket 2 of the main body 1 is moved upward, thus separating it from the main body 1.

[0040] When installing the main body 1 and the mounting bracket 2, after the mounting bracket 2 is snapped onto the surface of the main body 1, the positioning block 4 is inserted into the inside of the positioning groove 3 and moved to a suitable position to one side. Then, by rotating the rotating rod 6 to one side, the two rotating rods 9 are moved from the inside of the moving groove 7 into the inside of the two rotating grooves 8.

[0041] In this embodiment, the rotating rod 6, in conjunction with the moving groove 7, the rotating groove 8, and the rotating rod 9, limits the positioning block 4 and the mounting bracket 2. The positioning groove 3, in conjunction with the positioning block 4, limits the positioning of the body 1 and the mounting bracket 2. This facilitates the quick and easy installation and disassembly of the mounting bracket 2 and the body 1, and makes it easier to separate the body 1 from the tray later for maintenance.

[0042] Second embodiment:

[0043] Please refer to the following: Figure 4-5 Based on the chain line with precise pitch provided in the first embodiment of this application, the second embodiment of this application proposes another chain line with precise pitch. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0044] Specifically, the second embodiment of this application provides a chain line with precise pitch, which differs in that the surface of the rotating rod 6 is fixedly connected with a protective pad 18, and the inside of the rotating rod 6 is provided with a slot 12.

[0045] The rotating rod 6 is divided into two sections. One section has a slot 12, a moving hole 13 and a fixing hole 16 inside, while one end of the moving rod 14 is fixedly connected to one end of the other section.

[0046] One end of the slot 12 is provided with a moving hole 13, and a moving rod 14 is slidably connected inside the moving hole 13.

[0047] The slot 12 is a rectangular slot, and the block 15 is a rectangular slot. The moving hole 13 is larger than the slot 12. So when the moving rod 14 drives the fixing pin 17 to move to a suitable position to one side, the block 15 can rotate to one side inside the moving hole 13 when the moving rod 14 rotates to one side.

[0048] The movable hole 13 is opened inside the rotating rod 6, and the surface of the movable rod 14 is fixedly connected to the locking block 15.

[0049] The rotating rod 6 has a fixing hole 16 inside, and a fixing pin 17 is threaded into the fixing hole 16.

[0050] The fixing pin 17 is a threaded rod, and the fixing hole 16 is a threaded hole that is adapted to the fixing pin 17. When the fixing pin 17 rotates to one side inside the fixing hole 16, it moves to one side and drives the rotating rod 6 connected to the protective pad 18 to move to one side and contact one side of the body 1, thereby limiting the rotating rod 6.

[0051] In this embodiment, when it is necessary to rotate the rotating rod 6, the rotating rod 6 is rotated to one side, causing the moving rod 14 connected to the fixing pin 17 to rotate to one side and move to one side at the same time inside the fixing hole 16. After separating, the rotating rod 6 is pulled to one side, causing the locking block 15 to move to one side and enter the locking groove 12. Thus, when the rotating rod 6 is rotated to one side, the moving rod 14 connected to the locking block 15 is rotated to one side, causing the other section of the rotating rod 6 to drive the two rotating rods 9 to rotate to one side.

[0052] In this embodiment, the rotating rod 6 is limited by the slot 12 in conjunction with the moving hole 13, the moving rod 14, the locking block 15, the fixing hole 16, the fixing pin 17, and the protective pad 18, thereby increasing the stability of the rotating rod 6 after it rotates to the appropriate position.

[0053] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
