[0002] A chain is a transmission component made up of many links connected by pins and other fasteners. It has a wide range of uses. In vehicles such as bicycles and motorcycles, it can transmit power from the engine or pedals to the wheels to drive the vehicle forward. In some mechanical devices, chains can be used to achieve transmission between different shafts. It can adapt to a large center distance and has high transmission efficiency. For example, it is used in some agricultural machinery, textile machinery and other equipment.

[0003] When assembling a chain, the outer chain plate needs to be fixedly installed on the outside of the pin plate to connect multiple links in the chain. The existing assembly method usually involves workers using hand tools to make an interference fit between the outer chain plate and the fixing pins in two adjacent pin plates, thereby installing the outer chain plate on the outside of the pin plate and connecting multiple links. This assembly method increases the labor cost, and the manual installation of the outer chain plate is slow, reducing the assembly efficiency of the outer chain plate. Utility Model Content

[0004] To address the technical problems of increased labor costs and low assembly efficiency of external chain pieces due to manual assembly in existing technologies, this utility model provides a pin-type external chain piece pressing assembly device.

Under the thrust of the buffer, the side wall of the connecting plate is always in contact with the push shaft in the thrust cylinder. A pneumatic clamping assembly is provided on the upper part of the main base plate to press down and assemble the outer chain links.

[0008] Furthermore, a side cylinder is provided between the positioning plate and the main bottom plate to drive the positioning plate to move towards the main material channel.

[0009] Furthermore, the positioning plate has multiple positioning grooves on the side wall end near the main material channel, and the bushing at the center of the chain can be embedded into the positioning grooves.

[0010] Furthermore, the pneumatic clamping assembly includes a hydraulic cylinder and an assembly rivet head. An upper plate is provided on the upper part of the main base plate, and a hydraulic cylinder is installed on the top of the upper plate. A side plate is also provided on the upper part of the main base plate. The side plate is located near the main material channel.

[0013] Furthermore, a mounting plate is slidably connected to the upper part of the connecting plate, and a side cylinder is installed on the side of the connecting plate. The drive shaft in the side cylinder is threadedly connected to the mounting plate, thereby driving the mounting plate to slide on the upper part of the connecting plate. A positioning plate is fixedly installed at the end of the mounting plate.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] In use, this invention involves placing the chain to be fitted with an outer link piece into the mounting groove, placing the outer link piece outside two adjacent pins in the chain, activating the side cylinder, which drives the positioning plate to move towards the chain via the mounting plate, fixing the chain position with the positioning groove and the rear limit steel blade. Then, the hydraulic cylinder in the pneumatic clamping assembly is activated, pressing the outer link piece down onto the upper part of two adjacent pins in the chain. Next, the thrust cylinder is activated, driving the positioning plate to move to the left via the connecting plate and mounting plate, causing the positioning plate to move the chain to the left.

Detailed Implementation

[0022] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0023] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The diagram shows a pin-piece outer chain piece pressing assembly device.

[0024] Reference Figures 1-4As shown, this utility model discloses a pin-piece outer chain piece pressing assembly device, including a frame 1, a main base plate 2 fixedly installed on the upper part of the frame 1, a main material channel 5 protruding upward from the upper part of the main base plate 2, a mounting groove 51 for placing the chain on the top of the main material channel 5, a positioning plate 61 slidably installed at the top of one side wall of the mounting groove 51, the positioning plate 61 slidably installed on the upper part of the main base plate 2, a side cylinder 63 for driving the positioning plate 61 to move towards the main material channel 5 is provided between the positioning plate 61 and the main base plate 2, and a bushing for stopping the chain at the center of the chain is provided inside the other side wall of the mounting groove 51. The positioning plate 61, located near the side wall end of the main material channel 5, has multiple positioning grooves 611. The bushing at the center of the chain can be embedded into these grooves. During use, the positioning plate 61 is driven by the side cylinder 63 to move towards the mounting groove 51, causing the bushing at the center of the chain to embed into the positioning groove 611. Under the thrust of the positioning plate 61, the bushing contacts the rear limiting steel blade 52, which acts as a stop, thus fixing the bushing at the center of the chain between the positioning groove 611 and the rear limiting steel blade 52, thereby fixing the chain position. A pneumatic clamping assembly for pressing down and assembling the outer chain links is located on the upper part of the main base plate 2.

[0025] Preferably, the pneumatic clamping assembly includes a hydraulic cylinder 32 and an assembly rivet head 35. An upper plate 31 is provided on the upper part of the main base plate 2, and the hydraulic cylinder 32 is installed on the top of the upper plate 31. A side plate 33 is also provided on the upper part of the main base plate 2. The side plate 33 is located near the main material channel 5. A slide table 34 is slidably connected to the side of the side plate 33 near the main material channel 5. The upper part of the slide table 34 is connected to the hydraulic cylinder 32, and the lower part is fixedly provided with the assembly rivet head 35. A boss is provided at the bottom edge of the assembly rivet head 35 for pressing and assembling the outer chain piece. In use, the chain is fixed in the mounting groove 51 by the positioning groove 611 and the rear limit steel knife 52. The outer chain piece is placed outside the pin piece in the chain, so that the mounting hole in the outer chain piece is aligned with the position of the fixing pin in the chain. The hydraulic cylinder 32 is activated, and the hydraulic cylinder 32 pushes the assembly riveting head 35 downward through the slide table 34. The boss at the bottom of the assembly riveting head 35 presses the outer chain piece downward, so that the fixing pin in the chain passes through the mounting hole in the outer chain piece and forms an interference fit with the mounting hole, thereby fixing the outer chain piece to the outside of the pin piece.

[0026] Reference Figure 5As shown, a pneumatic displacement assembly is provided at the bottom of the positioning plate 61 to drive the positioning plate 61 to slide to the left or right. The pneumatic displacement assembly drives the positioning plate 61, causing the chain to move to the left, so that the next outer chain piece to be assembled moves to the bottom of the pneumatic clamping assembly. The pneumatic displacement assembly includes a thrust cylinder 75 and a buffer 76. The thrust cylinder 75 is located at the upper edge of the main base plate 2, and a connecting plate 64 is slidably disposed on the upper part of the main base plate 2. Preferably, a slide rail 71 is provided on the upper part of the main base plate 2, and a slider 72 is provided at the bottom of the connecting plate 64. The slider 72 is slidably connected to the slide rail 71. A baffle 74 protrudes upward from the upper part of the main base plate 2. A buffer 76 is provided on the side wall of the baffle 74. One end of the buffer 76 is fixedly connected to the baffle 74, and the other end abuts against the connecting plate 64. Under the thrust of the buffer 76, the side wall of the connecting plate 64 is always in contact with the push shaft in the thrust cylinder 75. The buffer 76 ensures that the connecting plate 64 is always in contact with the push rod in the thrust cylinder 75, eliminating the need for other power transmission structures between the connecting plate 64 and the thrust cylinder 75, thus saving manufacturing costs. A mounting plate 62 is slidably connected to the upper part of the connecting plate 64. A side cylinder 63 is installed on the side of the connecting plate 64. The drive shaft in the side cylinder 63 is threadedly connected to the mounting plate 62, thereby driving the mounting plate 62 to slide on the upper part of the connecting plate 64. A positioning plate 61 is fixedly installed at the end of the mounting plate 62.

[0027] In use, the chain to be fitted with the outer chain piece is placed in the mounting groove 51, and the outer chain piece is placed outside two adjacent pins in the chain. The side cylinder 63 is activated, and the side cylinder 63 drives the positioning plate 61 to move towards the chain through the mounting plate 62. The positioning groove 611 and the rear limit steel knife 52 fix the position of the chain. Then, the oil cylinder 32 in the pneumatic pressing assembly is activated to press the outer chain piece down and assemble it on the upper part of two adjacent pins in the chain. Then, the thrust cylinder 75 is activated, and the thrust cylinder 75 drives the positioning plate 61 to move to the left through the connecting plate 64 and the mounting plate 62. The positioning plate 61 drives the chain to move to the left, so that the pins of the next set of outer chain pieces to be installed in the chain move to the lower part of the activated pneumatic pressing assembly for assembly. This structure is simple to operate and can quickly assemble the outer chain piece. Moreover, it does not require manual assembly with tools, saving labor costs and improving the installation efficiency of the outer chain piece.
