Description

TECHNICAL FIELD

[0001] The present application relates to the field of wire processing equipment, in particular to a wire bending and cutting machine for checking backlash. BACKGROUND

[0002] Backlash refers to the gap between the tooth surfaces of a pair of gears when they are engaged. This is a necessary parameter for smooth operation of gear engagement. In order to maximize its efficiency, a small distance needs to be reserved between the gears. Such gear engagement is called backlash. The existence of backlash ensures that the gears can smoothly engage during operation, avoiding excessive friction and noise due to direct contact. The existence of backlash helps to reduce vibration and noise during operation of the gears, improving the stability and life of the equipment.

[0003] The lead wire method (also known as tin wire, this paper takes tin wire as an example) is generally used to check the engagement gap of bevel gears. The appropriate diameter or thickness of the lead wire is selected and placed on both sides of the engagement. The gears are rotated and the lead wire is rolled into the engagement. Then the gears are reversed and the lead wire is removed. The thickness of the lead wire at each point is measured using a vernier caliper or micrometer. The thickness of the lead wire at each point represents the range of backlash thickness of the bevel gears under the current assembly. If the range of thickness of the lead wire at each point exceeds the set theoretical backlash range, it indicates that the bevel gear engagement structure assembled at this time has a problem of excessive or insufficient backlash.

[0004] When detecting the backlash of bevel gears, the tin wire needs to be bent multiple times and placed on the surface of the bevel gears for engagement and extrusion. The tin wire for detection needs to be cut to a specified length and bent a specified number of times. The preparation of the tin wire for measuring backlash is time-consuming and labor-intensive.

[0008] By adopting the above technical scheme, the tin wire input assembly on the rack is responsible for continuous supply of tin wire, the tin wire bending assembly realizes accurate bending of the tin wire, and forms the required wave shape. Subsequently, the tin wire cutting piece cuts the bent tin wire according to the specified frequency, ensuring that each piece of tin wire has the same length and shape. Finally, the tin wire collecting assembly collects the cut tin wire, facilitating subsequent use. The entire process has high automation degree, significantly reduces manual operation, and improves production efficiency.

The bending motor 31 is installed on the bending mounting top plate 13. In this embodiment, the size of the bending mounting top plate 13 is consistent with the size of the bending motor 31. The driving shaft of the bending motor 31 penetrates the bending mounting top plate 13 and extends into the gap between the bending mounting bottom plate 12 and the bending mounting top plate 13.

[0036] With reference to Figure 1 and Figure 2 , the driving shaft of the bending motor 31 is installed with a linkage driving gear 32 in the gap between the bending mounting bottom plate 12 and the bending mounting top plate 13.

The bending positioning connecting plate 16 is rotatably connected with a bending driving gear 33 and a bending driven gear 34 through bearings. The bending driving gear 33 is respectively engaged with the linkage driving gear 32 and the bending driven gear 34. The bending driving gear 33 and the bending driven gear 34 form a gear gap for the tin wire to pass through. The gear gap between the bending driving gear 33 and the bending driven gear 34 can be adjusted according to actual needs to adapt to different specifications of tin wire.

[0037] The bending driving gear 33 and the bending driven gear 34 form an L shape with the linkage driving gear 32. The gap between the bending driving gear 33 and the bending driven gear 34 is opposite to the unwinding roller 22.

The cylinder can be a double-acting cylinder, which has a faster response speed and a larger driving force. The pneumatic shear can be made of stainless steel material, which has high wear resistance and corrosion resistance. The cylinder and the pneumatic shear can be connected through a connecting rod, which ensures the accuracy and stability of the cutting action.

[0040] Referring to Figure 1 and Figure 2 The tin wire collecting assembly 5 includes a cutting anti-bounce frame 51, a collecting guide plate 52, a storage rack 53, and a storage box 54.

In the embodiment, the connection between the cutting anti-bounce frame 51 and the bending mounting frame 11 is in the vertical direction.

[0041] The bottom of the cutting anti-bounce frame 51 is integrally formed with an extension frame 511, which is larger than the cutting anti-bounce frame 51. The collecting guide plate 52 is installed on the extension frame 511 directly below the cutting anti-bounce frame 51, and the end of the collecting guide plate 52 away from the bending mounting frame 11 protrudes out of the cutting anti-bounce frame 51. The storage rack 53 is installed on the rack 1 directly below the extension frame 511, and the storage box 54 is placed on the storage rack 53 to collect the bent and cut tin wire that slides out of the guide plate. The collecting guide plate 52 can be made of stainless steel material, which has a smooth surface and is beneficial to the smooth sliding of the tin wire.

[0042] The implementation principle of the tooth gap inspection metal wire bending and cutting machine according to the embodiment of the application is as follows: the tin wire roll is sleeved on the unwinding shaft 21, the operator clamps the workpiece and inserts one end of the tin wire into the pre-designed through hole of the bending mounting frame 11 and is transmitted by the input protection sleeve 23, and finally enters the meshing entrance between the bending driving gear 33 and the bending driven gear 34. At this time, the bending motor 31 is started, the bending driving gear 33 rotates, the bending driven gear 34 and the bending driving gear 33 rotate towards each other to pull the tin wire into the tooth gap between the bending driving gear 33 and the bending driven gear 34, and at the same time, the bending protection top plate 14 is closed. The tin wire is bent between the tooth gap of the bending driving gear 33 and the bending driven gear 34, cut by the tin wire cutting part 4, and finally falls into the storage box 54 under the guidance of the collecting guide plate 52.
