DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, below will combine the drawings in the utility model embodiment, and the technical scheme in the utility model embodiment is clearly and completely described, obviously, the described embodiment is a part of the embodiment of the utility model, instead of all the embodiment. The components of the utility model embodiment described and shown in the drawing here can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the utility model.

[0021] As Figures 1 to 4As shown, this embodiment provides a C-axis rotary table clamping fixture, including a pneumatic clamping fixture 1, a C-axis rotary table 2, and a rotary table slip ring 3. A slip ring fixing bracket 21 is provided on the C-axis rotary table 2. The rotary table slip ring 3 includes an outer slip ring 31 and an inner slip ring 32. The inner slip ring 32 is slidably installed inside the outer slip ring 31. The outer slip ring 31 is locked by the slip ring fixing bracket 21. The pneumatic clamping fixture 1 is installed on the inner slip ring 32. Ventilation holes are provided on the outer slip ring 31 and the inner slip ring 32, which are interconnected. The inner slip ring 32 is interconnected with the air inlet end of the pneumatic clamping fixture 1.

[0022] Furthermore, the vent provided on the outer ring 31 of the slip ring is the outer slip ring air inlet 311.

[0023] Furthermore, several air inlets 311 are provided on the outer slip ring.

[0024] Furthermore, the vent hole provided on the inner ring 32 of the slip ring is the inner slip ring air outlet 321.

[0025] Furthermore, several air outlets 321 are provided on the inner slip ring.

[0026] Furthermore, the pneumatic clamping fixture 1 is provided with a pneumatic clamp 11 for holding the workpiece 4 being processed.

[0027] Furthermore, the pneumatic clamp 11 is a pneumatic three-jaw caliper.

[0028] Typically, the automation system is designed to be included before production. Five-axis manufacturers are required to install a rotary joint with inlet / outlet circuits in the center of the C-axis rotary table (position 2) to enable automatic clamping. However, most products on the market lack this feature, making it impossible to add it later. Alternatively, external wiring is used, but C-axis rotary machining causes cable tangling, easily interfering with processing, resulting in a high failure rate and unsightly, non-standard machining.

[0029] This invention uses a slip ring fixing bracket 21 to fix the outer ring 31 of the slip ring to the B-axis housing of the five-axis rotary table, and aligns it with the rotating shaft of the rotary table before installing and fixing the outer ring 31. The inner ring 32 of the slip ring is fixed to the C-axis rotary table surface. During machining, the inner ring 32 rotates synchronously with the C-axis rotary table. Gas is introduced into the outer shell of the slip ring, and the slip ring has a flow channel and a flow channel sealing ring inside (the flow channel is as follows). Figure 4 The first flow channel 6 and the second flow channel 7, the flow channel sealing rings are as follows Figure 4 The sealing ring 5 in the middle transfers the air source from the outer ring 31 of the slip ring to the inner ring 32 of the slip ring, and finally connects to the pneumatic clamping fixture 1; the pneumatic clamping fixture 1 automatically clamps the workpiece 4 through the pneumatic clamp 11 to realize the automated clamping function of the pneumatic clamping fixture 1. The flow channel is the cavity structure, and the flow channel sealing ring is a structure used to improve the sealing performance of the flow channel.

[0030] The design and application of large-diameter pneumatic slip ring solve the problem that the rotary table machining cannot realize automatic clamping function without center inlet and outlet air function. The rotary table has center inlet and outlet air function from the beginning of design, which can realize automatic clamping function.
