Description

Technical Field

[0001] The present application relates to the technical field of parts processing, and in particular to a fixing tool for milling a ball cage coupling retainer. Background Art

[0002] At present, the ball cage coupling is a commonly used coupling, which is particularly suitable for shaft transmission under working conditions with large inclination angles and restricted radial dimensions. The existing ball cage coupling is mainly composed of a ball cage outer ring, a star-shaped inner ring, a retaining frame, a driving shaft, a driven shaft and multiple steel balls. Among them, the retaining frame is an important part of the ball cage coupling, which is mainly used to isolate the steel balls and guide the steel balls to keep them in the ball cage outer ring.

[0003] In the related art, after the ball cage coupling retainer is roughly machined and formed, when it is necessary to drill holes in the retainer, the retainer is generally limited and fixed by a three-jaw chuck, and then the retainer is milled and drilled by a milling machine. However, in the actual production process, after some small retainers are processed, some large retainers need to be processed. Since the adjustment range of the three-jaw chuck is fixed, it cannot be used for clamping and fixing large retainers, and its applicability is poor, and it is very inconvenient to use.

[0004] In view of the above problems, a fixed tooling for milling the cage of a ball coupling is now designed. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] The embodiment of the present application provides a fixing tool for milling a ball cage coupling retainer, which can solve the problem in the related art that a three-jaw chuck cannot clamp and fix retainers of different sizes as needed.

[0031] See also Figure 1-Figure 6 A fixed tool for milling a ball cage coupling cage, comprising: a base 1, a three-jaw chuck 2, a driving assembly 3, a bottom plate 4, a lifting assembly 5 and a positioning assembly 6, wherein the three-jaw chuck 2 is rotatably arranged on one side of the base 1, and the driving assembly 3 is arranged on the base 1 and connected to the three-jaw chuck 2 to drive the three-jaw chuck 2 to rotate;

[0032] In this way, when a small retainer needs to be milled, the retainer can be clamped and fixed by the three-jaw chuck 2, and then the retainer is milled by the milling machine. After a hole is milled out of the retainer, the three-jaw chuck 2 is driven to rotate by the driving component 3, thereby driving the retainer to rotate a certain angle, so that the next hole can be milled by the milling machine. The retainer can be processed by repeating this cycle.

[0033] In the present application, the three-jaw chuck 2 is driven to rotate by the driving assembly 3, which is a prior art and is not an improvement point of the present application, so no further description is given;

[0034] The bottom plate 4 is located below the base 1, the lifting assembly 5 is arranged on the bottom plate 4 and connected to the base 1 to drive the base 1 to move closer to or away from the bottom plate 4, the positioning assembly 6 includes a positioning block 61, two groups of positioning disks 62 and a plurality of bolts 63, the two groups of positioning disks 62 are symmetrically arranged, and a clamping space 60 is formed between the two groups of positioning disks 62, the positioning block 61 is located in the three-jaw chuck 2, the positioning block 61 is fixedly connected to one of the positioning disks 62, and a plurality of bolts 63 all penetrate the two groups of positioning disks 62, and nuts 64 are sleeved on the bolts 63;

[0035] When the large-scale retaining frame needs to be processed, the lifting assembly 5 can be used to drive the base 1 away from the bottom plate 4, so that the base 1 will drive the three-jaw chuck 2 to move up, thereby increasing the height of the three-jaw chuck 2 and avoiding interference between the large-scale retaining frame and the milling machine worktable during clamping. Then the staff can put the positioning block 61 into the three-jaw chuck 2, and clamp and fix the positioning block 61 through the three-jaw chuck 2, so as to fix the positioning plate 62. Then the staff can put the retaining frame on the side of the positioning plate 62 away from the positioning block 61, and then put the other positioning plate 62 on the side of the retaining frame away from the positioning block 61, so as to put the retaining frame in the clamping space 60 between the two sets of positioning plates 62, and then a plurality of bolts 63 can be passed through the two sets of positioning plates 62, and the bolts 63 can be tightened by nuts 64, so that the two sets of positioning plates 62 are close to the two sides of the retaining frame. In this way, the large-scale retaining frame can be clamped and fixed by the two sets of positioning plates 62;

[0036] When the small holder needs to be clamped again, the positioning block 61 can be removed from the three-jaw chuck 2, and then the base 1 is driven away from the bottom plate 4 by the lifting assembly 5, so that the three-jaw chuck 2 is driven downward by the base 1, so that the height of the three-jaw chuck 2 can be lowered, and it will be more convenient for the staff to operate when loading and unloading the small holder;

[0037] In this way, the device can be used to clamp and fix retaining frames of different sizes, which can enhance the applicability of the device. Manufacturers do not need to purchase two sets of clamping equipment, which can reduce production costs and has strong practicality.

[0038] Furthermore, in this embodiment, a limiting ring 65 is provided on the opposite side of the two sets of positioning plates 62;

[0039] In this way, when the retaining frame is clamped and fixed by two sets of positioning plates 62, the two sets of limiting rings 65 can cooperate with the inner wall of the retaining frame. In this way, the limiting rings 65 can be used to limit the vertical direction of the retaining frame to avoid displacement of the retaining frame during the clamping and milling process, which affects the quality of the retaining frame. In this way, the stability of the large retaining frame during the clamping process can be guaranteed, and the practicality is strong.

[0040] Furthermore, an inclined surface 66 is provided on the outer side of one end of the limiting ring 65 close to the clamping space 60;

[0041] In this way, when the limiting ring 65 is inserted into the inner wall of the retaining frame, the inclined surface 66 can play a guiding role, so that the staff does not need to completely align the retaining frame with the limiting ring 65, which is convenient for the staff to operate and use.

[0042] The base 1 is provided with a plurality of guide sleeves 11, the bottom plate 4 is provided with a plurality of guide posts 41, and the plurality of guide posts 41 respectively penetrate through the plurality of guide sleeves 11 and are slidably connected thereto;

[0043] In this way, through the cooperation and limiting effect of the sliding connection between several guide sleeves 11 and guide columns 41, the moving direction of the base 1 can be guided and limited, so that the base 1 can only perform lifting and lowering movements, thereby preventing the base 1 from deflecting during the lifting process, causing displacement of the retaining frame, and affecting the processing of the retaining frame.

[0044] See also Figure 6In this embodiment, the lifting assembly 5 includes a transmission assembly 51 and two groups of connecting members 52. The two groups of connecting members 52 are symmetrically arranged. The connecting members 52 include a first connecting rod 521, a second connecting rod 522 and a connecting column 523. The first connecting rod 521 is hinged at the lower end of the base 1. The connecting column 523 passes through the lower end of the first connecting rod 521 and is rotatably connected thereto. The upper end of the second connecting rod 522 is sleeved on the connecting column 523 and is rotatably connected thereto. The lower end of the second connecting rod 522 is hinged on the bottom plate 4. The transmission assembly 51 is arranged on the two groups of connecting columns 523 to drive the two groups of connecting columns 523 to move closer to or farther from each other.

[0045] In this way, when the two groups of connecting columns 523 are driven to move closer to or away from each other through the transmission assembly 51, the connecting column 523 will drive the first connecting rod 521 and the second connecting rod 522 to rotate, so that the first connecting rod 521 and the second connecting rod 522 will drive the base 1 to move when they rotate. At the same time, through the cooperation and limiting effect of the sliding connection between the guide sleeve 11 and the guide column 41, the base 1 can only make a linear motion along the guide column 41. In this way, the base 1 can be pushed and pulled by the rotation of the first connecting rod 521 and the second connecting rod 522, thereby realizing the lifting and lowering of the base 1, which is convenient for use.

[0046] More specifically, in this embodiment, the transmission assembly 51 includes a threaded rod 511, a fixing block 512, and a through hole 513. One end of the threaded rod 511 passes through one of the connecting posts 523 and is rotatably connected thereto. The other end of the threaded rod 511 passes through another connecting post 523 and is threadedly connected thereto. The fixing block 512 is provided on the threaded rod 511, and the through hole 513 is provided on the fixing block 512.

[0047] In this way, when the height of the base 1 needs to be adjusted, the staff can insert the tool into the through hole 513 on the fixed block 512, and then rotate the threaded rod 511, so that the threaded rod 511 pushes the two connecting columns 523 closer to or away from each other through the threaded connection with one of the connecting columns 523, so that the base 1 can be driven to rise and fall through the first connecting rod 521 and the second connecting rod 522. At the same time, the self-locking property of the threaded connection between the threaded rod 511 and the connecting column 523 can prevent the first connecting rod 521 and the second connecting rod 522 from moving when the threaded rod 511 does not rotate, so that the stability of the device can be ensured and it has strong practicality.
