Description

Technical Field

[0001] This utility model relates to the field of precision machining, and in particular to the field of deburring cage pockets, specifically a dry ice deburring tool for cages. Background Technology

[0002] The cage has a high requirement for the pocket, and burrs are easily generated on the edge of the hole. It needs to be removed with a dry ice cleaning machine. This requires a person to hold the nozzle in one hand and the part in the other hand to manually remove the burrs. This is inefficient, and it is difficult to uniform the position, which will result in some burrs not being removed cleanly. Holding the part by hand will also cause the hole to be blocked, wasting dry ice. Summary of the Invention

[0016] This utility model proposes a dry ice deburring fixture for cages, used in the deburring process of cage pockets. This utility model does not limit the type of cage to be processed, but the structure of the base 1, bearing 2, product clamping transmission group 4 and product positioning group 5 is particularly suitable for automatically cleaning cage pockets after fixing the nozzle position in the dry ice cleaning machine.

[0017] In general, the dry ice deburring fixture for retainers proposed in this utility model mainly includes: a base 1, a bearing 2, a product clamping transmission group 4, and a product positioning group 5. (See also...) Figure 1 It shows the arrangement of the base 1, bearing 2, product pressing transmission group 4 and product positioning group 5.

[0018] Before using the dry ice deburring fixture for retainers proposed in this utility model, remove the positioning block 53 and the locking knob 45 in sequence. When using it, put the retainer 6 to be processed on the outside of the drive rod 43, and then put the positioning block 53 back on the drive rod 43 so that the positioning block 53 can completely cover the top of the retainer 6. Loosen the bolt 55 so that the positioning block 53 moves back and forth along the positioning block mounting groove 51 and abuts against the outer wall of the retainer 6. Tighten the bolt 55 into the threaded hole 52 to lock the position of the retainer 6. Turn the locking knob 45 back to lock the retainer 6 on the turntable 3. The nozzle in the dry ice cleaning machine is fixedly aligned with the retainer 6. Manually rotate the turntable 3 and start the dry ice cleaning machine to automatically clean the pockets on the retainer 6.

[0019] The base 1 has a rotating groove 11 in the center. The bottom of the bearing 2 is placed in the rotating groove 11. The outer ring of the top of the bearing 2 is fitted with a turntable 3 with an interference fit. The bottom center of the turntable 3 has an installation groove 31. The installation groove 31 fits with the outer ring of the bearing 2 so that the turntable 3 can be rotated relatively easily by the thrust generated by the nozzle in the dry ice cleaning machine in conjunction with the bearing 2.

[0020] The aforementioned product clamping transmission assembly 4 is installed in the center of the turntable 3. The product clamping transmission assembly 4 includes: a light hole 41, a drive rod 43, a pressure plate 44, and a locking knob 45. The light hole 41 is located in the center of the top of the turntable 3 and is coaxially arranged with the mounting groove 31. A drive groove 42 is provided between the light hole 41 and the mounting groove 31. The bottom of the drive rod 43 is locked in the drive groove 42, and the top of the drive rod 43 extends straight upward through the light hole 41. The pressure plate 44 is sleeved on the top of the drive rod 43. The outer diameter of the pressure plate 44 is larger than the inner diameter of the retainer 6, otherwise clamping cannot be achieved. The top of the drive rod 43 is provided with an external thread, and the locking knob 45 is located on the top of the pressure plate 44. The locking knob 45 is sleeved on the outer side of the top of the drive rod 43 through a threaded fit.

[0021] The aforementioned product positioning group 5 is located on the outside of the product pressing transmission group 4 on the turntable 3. The product positioning group 5 includes: positioning block mounting grooves 51, threaded holes 52, and positioning blocks 53. The positioning block mounting grooves 51 are located at the top of the turntable 3, and there are three positioning block mounting grooves 51. The three positioning block mounting grooves 51 are evenly spaced at 90° intervals on the outside of the light hole 41. The threaded holes 52 are evenly spaced at the bottom of the positioning block mounting grooves 51. The positioning blocks 53 are locked in the positioning block mounting grooves 51, and the side of the positioning block 53 closest to the drive rod 43 is the top. 56. An elongated hole 54 is provided in the center of the other side of the positioning block 53. A bolt 55 is inserted into the elongated hole 54. The bottom of the bolt 55 is locked in the threaded hole 52. The product positioning group 5 provides a certain support force when the cage 6 rotates. However, its main function is to quickly install and position the cage. Limiting the positioning to three sides is to facilitate the assembly of the cage 6 when loading materials. If the positioning to four sides were limited, it would cause the positioning block 53 to be disassembled and reassembled repeatedly during batch production. In this design, after the positioning block 53 is adjusted for the first time during batch production of the same batch of cages, the positioning block 53 does not need to be adjusted again in subsequent production, thus improving production efficiency.

[0022] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
