Description

Technical Field

[0001] The utility model relates to a pulley mounting frame structure. Background Art

[0002] The embroidery frame of the embroidery machine is equipped with pulleys on the longitudinal and transverse drive frames. The pulley is provided with a mounting seat, which is formed by cutting an aluminum profile. The mounting seat is provided with a pulley shaft hole for installing the pulley, a first connecting hole for connecting the base, and a second connecting hole for connecting the end plate. After the aluminum profile is cut, it needs to be punched. The shaft hole, the first and second connecting holes are located on different end faces of the aluminum profile, so it is necessary to punch after multiple clamping. The cost of multiple clamping processes is high, and multiple clamping is likely to affect the processing accuracy.

[0003] Since the cutting precision of aluminum profiles is not high, the reference surface needs to be processed after cutting to facilitate drilling through the reference surface. At the same time, the clamping requires high tooling and may require multiple sets of tooling. Therefore, the production cost of the aluminum profile mounting seat is relatively high. Summary of the invention

[0004] The utility model aims to solve the problems existing in the prior art during use and provides a pulley mounting frame structure which has a relatively simple structure and can effectively reduce the pulley mounting cost.

[0005] The utility model provides a technical solution to the existing problem: a pulley mounting frame structure, comprising a bottom plate of a sheet metal part, a pulley mounting plate formed by bending at both sides of the bottom plate, and an end surface connecting plate formed by bending at one end of the bottom plate, wherein a first group of connecting holes is provided on the bottom plate, a second group of connecting holes is provided on the end surface connecting plate, and a pulley connecting hole is provided on the pulley mounting plate.

[0006] As a further improvement, the first group of connection holes is provided with at least two first connection holes, and the at least two first connection holes are arranged along the axial direction of the pulley connection hole.

[0007] As a further improvement, the first connecting hole is a long slot hole with an adjustable installation position, and the length direction of the long slot is perpendicular to the axial direction of the pulley connecting hole.

[0008] As a further improvement, the second group of connection holes is provided with at least two second connection holes, and the at least two second connection holes are arranged along the axial direction of the pulley connection hole.

[0009] As a further improvement, the pulley connecting hole is a precision-machined connecting hole.

[0010] As a further improvement, the outer periphery of the pulley mounting plate located at the pulley connecting hole is provided with a first positioning annular surface protruding toward the inner side of the pulley mounting plate.

[0011] As a further improvement, the pulley mounting plate is located on the outer side of the pulley connecting hole and is provided with a sunken second positioning annular surface.

[0012] As a further improvement, a gap groove is provided between the pulley mounting plate and the end surface connecting plate.

[0013] Compared with the prior art, the utility model has pulley mounting plates bent on both sides of the bottom plate of the sheet metal part, and an end surface connecting plate bent at one end of the bottom plate. The bottom plate, mounting plate, and end surface connecting plate can be mass-produced by sheet metal stamping, and the corresponding connecting holes thereon can also be stamped during the sheet metal processing process. Only necessary debugging is required during stamping to ensure that the corresponding connecting holes reach the required use accuracy, or to ensure that the corresponding connecting holes can meet the use requirements through a small amount of fine processing. The beneficial effect is that the pulley mounting frame of the sheet metal part can be easily mass-produced quickly, the processing technology of the pulley mounting frame is reduced, and the cost of the pulley mounting frame is effectively reduced.

[0019] See also Figure 1-5 In this embodiment, a pulley mounting frame structure is provided, including a bottom plate 1 of a sheet metal part, a pulley mounting plate 2 formed by bending at both sides of the bottom plate 1, and an end surface connecting plate 3 formed by bending at one end of the bottom plate 1. The bottom plate 1 is provided with a first group of connecting holes 11, the end surface connecting plate 3 is provided with a second group of connecting holes 31, and the pulley mounting plate 2 is provided with a pulley connecting hole 21. The bottom plate 1, the pulley mounting plate 2, the end surface connecting plate 3 and the corresponding connecting holes thereon can all be formed by stamping, and then bent by stamping to form the final pulley mounting frame. The bending and the corresponding connecting holes can be quickly formed in batches after corresponding stamping debugging.

[0020] The first group of connection holes 11 is provided with at least two first connection holes, and at least two first connection holes are arranged along the axial direction of the pulley connection hole 21. The first connection hole is a long slot hole with adjustable installation position, and the length direction of the long slot is perpendicular to the axial direction of the pulley connection hole 21.

[0021] The second group of connection holes 31 is provided with at least two second connection holes, and the at least two second connection holes are arranged along the axial direction of the pulley connection hole 21 .

[0022] Usually, the first connection hole and the second connection hole are only used to fasten the mounting frame, so the relative accuracy is relatively low. The punching and bending base plate can fully meet the use accuracy requirements. The first connection hole is a long slot hole with adjustable installation position, which can be adjusted to adapt to the installation position through installation, and the accuracy requirements of the first connection hole are relatively reduced. The first and second connection holes can be set to two.

[0023] The pulley connection hole 21 usually requires a certain degree of precision. If punching and bending cannot meet the precision requirements, the pulley connection hole 21 can be set as a finely machined connection hole. Appropriately slight fine machining of the pulley connection hole 21 can improve the precision of the pulley connection hole.

[0024] Further, for ease of use, the outer periphery of the pulley mounting plate 2 at the pulley connection hole 21 is provided with a first positioning annular surface 22 protruding toward the inner side of the pulley mounting plate 2. The outer side of the pulley mounting plate 2 at the pulley connection hole 21 is provided with a sunken second positioning annular surface 23.

[0025] A gap groove 4 is provided between the pulley mounting plate 2 and the end surface connecting plate 3 to facilitate bending of the pulley mounting plate 2 and the end surface connecting plate 3 .

[0026] When the structure of the utility model is used, the pulley mounting frame can be installed on the end seat 5 through the first group of connecting holes 11 on the bottom plate 1, and the end face of the end seat 5 is provided with an end plate 6, which can be installed and connected to the end face connecting plate 3 through the second group of connecting holes 31. A necessary connecting block can be arranged between the end plate 6 and the end face connecting plate 3, and the pulley is installed in the pulley connecting hole 21 of the pulley mounting plates 2 on both sides through the pulley shaft, and finally the end seat 5 is installed and connected to the frame body 7 of the driving frame. The pulleys at both ends of the frame body 7 of the driving frame cooperate with each other, and one of the pulleys is used as a driving pulley to drive the belt located on the pulley, so that the connecting block on the belt is driven by the belt to slide, thereby realizing the driving of the embroidery frame.
