Description

Technical Field

[0001] This utility model relates to the field of braiding machine equipment, specifically to a splicing mainboard structure for a large braiding machine. Background Technology

[0002] Commonly used braiding machine mainboards are made from integral cast plates or steel plates. Due to the standardized length and width dimensions of steel plates purchased from the market, the size is limited. Conventional small braiding machines can meet this requirement, but the mainboard material for large braiding machines cannot be manufactured from a single piece of material. It can only be manufactured by splicing multiple pieces. Splicing multiple pieces will produce manufacturing errors, assembly errors, and will also affect the long-term stability of the machine. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model proposes a splicing motherboard structure for large-scale braiding machines. The design is ingenious, the structure is reasonable and compact, and it is easy to process and manufacture, thus meeting the requirements for the use of motherboards in large-scale braiding machines.

[0004] The technical solution of this utility model:

[0005] The large-scale braiding machine splicing main board structure includes a first main board, a second main board, a first auxiliary board, and a second auxiliary board. The first and second main boards are connected by the first and second auxiliary boards. Several fixing holes are opened on both sides of the first and second auxiliary boards. Adjacent edges of the first and second main boards are spliced ​​together, and several threaded holes are correspondingly opened at both ends of the adjacent edges. The fixing holes on the first and second auxiliary boards correspond to the threaded holes on the first and second main boards, respectively, and are fixed by screws passing through the fixing holes and screwing into the threaded holes. The flatness of the mating surfaces of the first and second main boards and the first and second auxiliary boards is less than 0.02mm. The section of the screw shank near the upper nut is designed as a smooth shank, and the outer diameter of the smooth shank is the same as the inner diameter of the fixing hole.

[0006] The first motherboard and the second motherboard have several semi-circular protrusions on their adjacent outer sides, and the second motherboard has several semi-circular grooves on their adjacent outer sides. The semi-circular protrusions and the corresponding semi-circular grooves are spliced ​​and matched. The semi-circular protrusions have threaded holes in the middle.

[0007] The first and second sub-boards are configured to be of any shape without affecting the installation and use of motherboard components.

[0008] The first and second sub-plates are rectangular, with arc-shaped notches reserved at the two inner corners to avoid other components on the upper part of the main board of the weaving machine.

[0009] The motherboard design consists of at least two boards, and the sub-board design consists of at least two boards.

[0010] The thickness of the sub-plate is designed to be adjustable.

[0011] The advantages of this utility model are its ingenious design and reasonable, compact structure. It uses multiple main boards connected by designed sub-boards to form a large main board, solving the problem that large-sized main boards cannot be directly processed from standardized steel plates. The flatness of the mating surfaces of the main boards and sub-boards is designed to be less than 0.02mm, ensuring that the two main boards are in a straight line and guaranteeing the installation accuracy of the main boards. The sub-boards used for splicing main boards in large braiding machines can be designed in various shapes and thicknesses according to the distribution of main board parts, so that the sub-boards do not affect the normal use accuracy and strength of the main boards. The thickness of the sub-board material can be changed to increase the rigidity and flatness accuracy of the spliced ​​main boards. Attached Figure Description

[0014] See attached document Figure 1-2 The large-scale braiding machine splicing main board structure includes a first main board 1, a second main board 2, a first auxiliary board 3, and a second auxiliary board 4. The first main board 1 and the second main board 2 are connected by the first auxiliary board 3 and the second auxiliary board 4. The first auxiliary board 3 and the second auxiliary board 4 have several fixing holes on both sides. The adjacent edges of the first main board 1 and the second main board 2 are spliced ​​together, and several threaded holes are correspondingly opened at both ends of the adjacent edges. The first auxiliary board 3 and the second auxiliary board 4 are fixed by screws 5, which pass through the fixing holes and are screwed into the threaded holes. The flatness of the mating surfaces of the first main board 1, the second main board 2, the first auxiliary board 3, and the second auxiliary board 4 is less than 0.02mm. The section of the screw shank near the upper nut is designed as a smooth shank, and the outer diameter of the smooth shank is the same as the inner diameter of the fixing hole. The same diameter of the smooth shank and the fixing hole allows for precise positioning and avoids errors. The flatness design effectively improves installation accuracy.

[0015] The first motherboard 1 and the second motherboard 2 are provided with a number of semi-circular protrusions 6 on the outer side of their adjacent sides, and the second motherboard 2 is provided with a number of semi-circular grooves 7 on the outer side of its adjacent sides. The semi-circular protrusions and the corresponding semi-circular grooves 7 are spliced ​​and matched. The semi-circular protrusions 6 are provided with threaded holes 8 in the middle.

It features high machining precision, ease of assembly, and ensures high mainboard installation accuracy; the flatness of both the mainboard and sub-plate is less than 0.02mm. The sub-plate is machined from steel plates that have undergone surface grinding. The mainboard size is determined by selecting two or more pieces for splicing, and the size and shape of the sub-plate are chosen accordingly. The sub-plate is mounted on the machined and flat mainboard. Multiple threaded holes on the mainboard are designed to secure the sub-plate, ensuring the two mainboard planes are aligned and guaranteeing installation accuracy. The sub-plate is designed in various shapes and thicknesses based on the distribution of the mainboard components, ensuring it does not affect the normal operating accuracy and strength of the mainboard. The sub-plate can be mass-produced and used for splicing mainboards in different models of braiding machines. The material thickness of the sub-plate can be varied to increase the rigidity and flatness accuracy of the spliced ​​mainboard.
