Description

Technical Field

[0001] The invention relates to the technical field of roller processing, and in particular to a multi-station workbench used for roller oblique hole processing and a processing method thereof. Background Art

[0002] Rollers are an important part of textile machinery. Rollers are usually cylindrical and their main functions are to feed, draft and output yarn. Hundreds or even thousands of rollers need to be installed on a textile machinery. According to different uses and positions, they can be divided into drafting rollers, feeding rollers, pressing rollers, working rollers, etc. In the spinning process, the quality of the rollers directly affects the uniformity of the output yarn.

[0003] like Figure 1 As shown, this is a common roller. This roller needs to process oblique holes. According to actual needs, select appropriate holes for processing. For example, it is necessary to process two holes, hole 1 701 and hole 2 702, or hole 1 701 and hole 3 70, or hole 1 701, hole 2 702, hole 3 703 and hole 4 704. The specific process includes point hole-drilling-tapping-chamfering (for Figure 1 The purpose of chamfering the openings A and B of the four holes 701, 702, 703 and 704 is to make the two openings of the holes smoother and free of burrs, so as to facilitate the installation of the bolts and roller shafts. However, the inventors of the present application found that there are still many problems in the traditional process of processing inclined holes during implementation, such as:

[0004] 1. When processing the roller, it is necessary to punch, tap and chamfer the roller at an angle of about 45°, which leads to problems such as great difficulty in processing the inclined holes of the roller and poor quality of the inclined holes.

[0005] 2. When making inclined holes on rollers, only a single roller can be processed at a time. After processing one roller, manual loading and unloading is required, resulting in high labor intensity. In addition, the equipment needs to be stopped during the loading and unloading process, resulting in low roller production efficiency, which is not conducive to mass production of rollers.

[0006] 3. Roller holes are generally tapped first, and then the threaded holes are polished and chamfered, that is, tapping comes first and chamfering comes later. Chamfering will damage the threaded holes and affect the installation of the bolts.

[0007] 4. The chamfering operation in the traditional process is based on manual work, that is, manual grinding is performed on the places where the holes need to be chamfered with a grinder. When chamfering manually, the position is not accurately grasped, especially when chamfering the hole B, the error is large, which will lead to a high defective rate of processed products, which is not conducive to the development of the enterprise.

It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0056] Embodiment 1:

[0057] Please refer to Figure 2-4 A multi-station workbench used for roller oblique hole processing includes a base 1, supports 2 are arranged on both sides of the base 1, the supports 2 are fixed to the base 1 by fasteners, and an inclined and rotatable bearing plate 3 is arranged between the two supports 2; it also includes 5 groups of fixing mechanisms 4, and the fixing mechanisms 4 are installed on the bearing plates 3 and are in an inclined state.

[0058] Based on the above scheme, it can be expected that the fixing mechanism 4 can fasten the roller 7 to facilitate the processing of the roller 7, and the inclined supporting plate 3 makes the roller 7 fixed on the fixing mechanism 4 also appear inclined, and the angle between the inclination angle and the horizontal plane is about 45°, so that the hole position 1 701 or the hole position 3 703 to be processed is turned into a vertical state, and the hole position 1 701 or the hole position 3 703 is processed in the vertical state using a processing head, which facilitates the processing of a 45° inclined hole on the roller 7.

[0059] As a preferred embodiment, each set of fixing mechanisms 4 includes a first driving device 401, a chassis 402, a tensioning sleeve 403 and a driving member 404. The first driving device 401 is installed on one side of the supporting plate 3, and the chassis 402 is installed on the other side of the supporting plate 3. A cavity is opened inside the chassis 402. The tensioning sleeve 403 is a hollow structure and is installed in the cavity of the chassis 402. One end of the driving member 404 is installed on the output shaft of the first driving device 401, and the other end passes through the supporting plate 3 and is located inside the tensioning sleeve 403.

[0060] Based on the above scheme, it is foreseeable that when the first driving device 401 works, the output shaft of the first driving device 401 retracts, driving the driving member 404 to retract. When the driving member 404 retracts, it applies an outward expansion force to the tensioning sleeve 403 to expand the tensioning sleeve 403, thereby fixing the roller 7 through the internal expansion principle.

[0061] Furthermore, a tensioning head 4031 is provided on the top of the tensioning sleeve 403, and the tensioning head 4031 and the tensioning sleeve 403 are an integrated structure. The tensioning head 4031 is a funnel-shaped structure that is larger at the top and smaller at the bottom. A driving head 4041 is provided on the driving member 404, and the driving head 4041 and the driving member 404 are an integrated structure, and the driving head 4041 is adapted to the tensioning head 4031.

[0062] Based on the above scheme, it is foreseeable that when the driving member 404 retracts, it will drive the tensioning head 4031 to move together, so that an outward expansion force is applied to the tensioning head 4031 through the tensioning head 4031 to expand the tensioning head 4031, and the roller 7 is fixed by the internal expansion principle.

[0063] Furthermore, the tension sleeve 403 and the tension head 4031 are provided with a plurality of equally spaced split grooves 4032, and the split groove 4032 runs through one end of the tension head 4031. The design of the split groove 4032 enables the tension sleeve 403 and the tension head 4031 to expand when subjected to external force.

[0064] In this embodiment, the first driving device 401 is a cylinder.

[0065] Embodiment 2:

[0066] Please refer to Figure 2 , 5 -8, a multi-station workbench used for roller 7 inclined hole processing, also includes two sets of rotating mechanisms 5, the two sets of rotating mechanisms 5 are respectively located on both sides of the bearing plate 3.

[0067] Based on the above scheme, it is foreseeable that the rotating mechanism 5 can drive the supporting plate 3, the fixing mechanism 4 and the roller 7 to rotate, that is, the direction of the roller 7 can be changed by the rotating mechanism 5, thereby facilitating the processing of the hole position on the other inclined surface of the roller 7.

[0068] As a preferred embodiment, the rotating mechanism 5 includes a second driving device 501, a rack 502, a gear 503, a bearing 504 and a transmission shaft 505. The second driving device 501 is installed on the support 2, and its output shaft passes through the support 2 and is connected to the rack 502. One end of the transmission shaft 505 is connected to the supporting plate 3, and the other end passes through the support 2 and is connected to the gear 503. The gear 503 is meshed with the rack 502, and the bearing 504 is installed between the support 2 and the transmission shaft 505.

[0069] Based on the above scheme, it can be expected that Figure 6 and 7 As shown, the second driving device 501 works, and its output shaft extends, driving the rack 502 to move outward. At this time, the gear 503 will rotate counterclockwise, thereby driving the supporting plate 3 to rotate counterclockwise, and its rotation angle is about 90°, so that the hole position two 702 or hole position four 704 to be processed becomes a vertical state, which is convenient for the processing of hole position two 702 or hole position four 704; it rotates in the opposite direction, so that the hole position one 701 or hole position three 703 to be processed becomes a vertical state, which is convenient for the processing of hole position one 701 or hole position three 703.

[0070] Furthermore, two support members 6 are provided on the base 1. The support members 6 are located below the rack 502, and the top surfaces of the support members 6 are in contact with the lower surfaces of the rack 502. The support members 6 are installed on the base 1 to support the rack 502, so that the rack 502 can move horizontally without deviating from the established track.

[0071] In this embodiment, the support member 6 is a bolt, and the support member 6 is fixed to the base 1 by means of threads. The bolt has a simple structure and low cost.

[0072] Furthermore, a limiting plate 8 is provided on the top of the support 2, and the limiting plate 8 is fixed to the top of the support 2 by fasteners. Two cut corners 301 are respectively provided at both ends of the bearing plate 3, and the two cut corners 301 at the same end of the bearing plate 3 are symmetrically arranged. The cut corners 301 are used in conjunction with the limiting plate 8 to limit the rotation angle of the bearing plate 3. The cross-section of the notch formed by the cut corners 301 is an equilateral right triangle, so that the maximum rotation angle of the bearing plate 3 clockwise or counterclockwise is about 90°, that is, after rotating 90°, the edge of one side of the cut corner 301 will conflict with the bottom surface of the limiting plate 8 (such as Figure 6 The support plate 3 is prevented from rotating further in the original direction, thereby limiting the rotatable angle of the support plate 3.

[0073] In this embodiment, the second driving device 501 is a cylinder, which achieves the purpose of automatically changing the angle of the carrier plate through the engagement of the cylinder and the gear rack. That is, after completing the processing of the inclined hole on one side of the roller, it can automatically change direction and the angle is accurate.

[0074] Embodiment 3:
