Description

Technical Field

[0001] This invention relates to the field of machine tool component technology, and in particular to a tooling for machining large circular kiln tripods. Background Technology

[0002] The main cauldron of the circular knitting machine is the core transmission component. Its main function is to drive the cylinder to rotate and drive the knitting system. Its structural design directly affects the accuracy, stability and ease of operation of the equipment. The cauldron is driven by an electric motor, which transmits power to the drive shaft gear through a V-belt or synchronous belt, thereby driving the cylinder carrying the knitting needles to rotate at high speed to complete the knitting process.

[0003] The machine adopts a drive-type cauldron structure, which eliminates assembly errors of traditional direct-drive machines and ensures stability during high-speed operation. Some models feature a fully oil-immersed design, improving lubrication and reducing wear. The needle timing device can be adjusted at a single point through the side observation window and adjustment hole, eliminating the need for operation on the top of the cauldron. The yarn feeding drive adopts a centralized enclosed design, reducing cotton lint interference and simplifying maintenance.

[0004] When turning a large cauldron, it is necessary to accurately locate its axis of rotation and stabilize its position during turning. The cauldron also needs to be clamped during machining, but the existing clamping methods are inconvenient when clamping the cauldron and fine-tuning its position. Summary of the Invention

[0013] Preferably, the adaptive support frame has an extrusion bearing column on the side near the large circular kiln workpiece, and the inclined rail is installed on the extrusion bearing column.

[0014] Preferably, the gravity pushing device includes a gravity compression slider and a gravity compression adaptation block.

[0016] The beneficial effects of this invention are:

[0017] The machining fixture includes a workpiece fixing system and a gravity balancing system.

The force-pushing device presses down on the workpiece of the large circular knitting machine at all times to ensure the stability of the workpiece during turning. During turning, the workpiece may vibrate as the rotary device rotates and as the turning system performs the turning. When the workpiece vibrates, the gravity-pushing device, under its own gravity, adaptively presses down on the side wall of the workpiece in real time to ensure stable clamping of the workpiece.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figure 1 — Figure 4 As shown, this embodiment provides a machining fixture for turning a large circular kiln tripod, which is installed on a vertical lathe. This machining fixture is used to clamp the large circular kiln tripod workpiece. The vertical lathe includes a rotary device 1, a frame 2, and a turning system 3. The machining fixture includes a workpiece fixing system 4 and a gravity balancing system 5. The gravity balancing system 5 is installed on the frame 2 and is connected to the turning system 3. The gravity balancing system 5 slides up and down along the frame 2, reducing the lifting resistance of the turning system 3. The workpiece fixing system 4 includes a workpiece fixing base plate 41 and several adaptive supports 42. The workpiece fixing base plate 41 is installed on the rotary device 1, and the adaptive supports 42 are installed on the workpiece fixing base plate 41. Each adaptive support 42 clamps the large circular kiln tripod workpiece.

[0031] Specifically, the adaptive support 42 includes an adaptive support frame 421, a gravity jacking device 422, and an adaptive fixing device 423. The adaptive support frame 421 has a long groove 4211, and the adaptive fixing device 423 is installed on the long groove 4211 to lock the adaptive support frame 421 onto the workpiece fixing base plate 41. The adaptive support frame 421 has an inclined rail 4212, and the gravity jacking device 422 is slidably installed on the inclined rail 4212. The angle between the inclined rail 4212 and the vertical line is 5 to 10 degrees. The gravity jacking device 422 is located near the workpiece of the large circular kiln on the adaptive support frame 421. On one side, when the gravity jacking device 422 slides along the inclined rail 4212 under the action of gravity, it approaches the workpiece of the large circular knitting machine, so that the gravity jacking device 422 presses down on the workpiece of the large circular knitting machine at any time, ensuring the stability of the workpiece during turning. During turning, when the workpiece of the large circular knitting machine rotates with the rotary device 1 and when the turning system 3 turns, the workpiece of the large circular knitting machine may vibrate. When the workpiece of the large circular knitting machine vibrates, the gravity jacking device 422, under the action of its own gravity, adaptively presses down on the side wall of the workpiece of the large circular knitting machine in real time, ensuring the stable clamping of the workpiece of the large circular knitting machine.

[0032] Specifically, the rotary device 1 includes a rotary table, a rotary bearing, and a rotary motor. The rotary table is mounted on the frame 2 via the rotary bearing, and the rotary motor is mounted on the frame 2. The rotary motor is connected to the rotary table via a transmission connection. The rotary table rotates via the rotary bearing, and the rotary motor drives the rotary table to rotate, thereby realizing the rotary turning of the workpiece.

[0033] Specifically, the turning system 3 includes a turning lifting device 31 and a turning transverse device 32. The turning lifting device 31 is slidably mounted on the frame 2 in the lifting direction, and the turning transverse device 32 is slidably mounted on the turning lifting device 31 in the horizontal direction. The gravity balance system 5 is connected to the turning lifting device 31 in a transmission connection. The gravity balance system 5 balances the gravity of the turning system 3, which facilitates the lifting and lowering of the turning system 3.

[0034] Specifically, the turning lifting device 31 includes a turning lifting motor 311 and a turning lifting slide block 312. The turning lifting motor 311 is mounted on the machine frame 2, and the turning lifting slide block 312 moves up and down along the machine frame 2. The output end of the turning lifting motor 311 is connected to the turning lifting slide block 312 in a transmission connection. The turning lifting slide block 312 is connected to the gravity balance system 5 in a transmission connection. The turning lifting motor 311 drives the turning lifting slide block 312 to move up and down. The turning transverse movement device 32 is mounted on the turning lifting slide block 312, and the cutting tool is mounted on the turning transverse movement device 32. The rising and falling of the turning lifting motor 311 drives the cutting tool to rise and fall, thereby realizing the turning feed.

[0035] Specifically, the turning transverse device 32 includes a tool transverse box 321 and a tool transverse motor 322. The tool transverse motor 322 is mounted on the turning lifting device 31. The tool transverse box 321 is slidably mounted on the turning lifting device 31 in the horizontal direction. The tool transverse motor 322 is connected to the tool transverse box 321 in a transmission connection. The cutting tool is mounted on the tool transverse box 321. The tool transverse motor 322 drives the cutting tool to move and change the turning depth.

[0036] Specifically, the gravity balance system 5 includes a gravity block 51, a gravity traction rope 52, and a traction rope guide frame 53. The gravity block 51 is slidably mounted on the frame 2 along the lifting direction. The two ends of the gravity traction rope 52 are respectively mounted on the turning system 3 and the gravity block 51. The gravity traction rope 52 passes around the traction rope guide frame 53, and the traction rope guide frame 53 lifts the gravity traction rope 52 upward. The gravity block 51 balances the gravity of the turning system 3 and reduces the resistance to the movement of the turning system 3.

[0037] Specifically, the adaptive support frame 421 has an extrusion bearing column 4213 on the side near the large circular kiln workpiece, and the inclined rail 4212 is installed on the extrusion bearing column 4213, so that the inclined rail 4212 has sufficient length.

[0038] Specifically, the gravity pushing device 422 includes a gravity extrusion slider 4221 and a gravity extrusion adaptation block 4222. The gravity extrusion adaptation block 4222 is mounted on the gravity extrusion slider 4221 via a ball head. The gravity extrusion slider 4221 is slidably mounted on the inclined rail 4212. Under the gravity of the gravity extrusion slider 4221, the gravity extrusion adaptation block 4222 adaptably extrudes the large circular machine cauldron workpiece.

[0039] In this application, when adjusting the position of the large circular kiln workpiece, the large circular kiln workpiece is placed on the workpiece fixing base plate 41. Permanent magnets for attracting gravity-pressing sliders 4221 are placed on each adaptive support 42, so that each gravity-pressing slider 4221 is in its upper limit position. The adaptive support 42 is locked onto the workpiece fixing base plate 41 in a manner that surrounds the large circular kiln workpiece. Then, each permanent magnet is removed, so that each gravity-pressing adaptive block 4222 presses down on the large circular kiln workpiece. A micrometer is installed on the turning system 3, and the rotary device 1 is started to move the large circular kiln workpiece. Rotate slowly, and reposition the permanent magnets according to the positional deviation indicated by the micrometer. This causes the gravity extrusion sliders 4221 to rise and disengage from the workpiece of the large circular kiln machine, pushing the workpiece to slide horizontally on the workpiece fixing base plate 41. This adjusts the horizontal position of the workpiece until its position is determined. Once the position is determined, remove the permanent magnets again, causing the gravity extrusion adaptation blocks 4222 to press down on the workpiece. This avoids frequent disassembly of the adaptation support 42, greatly facilitating tool setting.

[0040] Specifically, the adaptive fixing device 423 includes a fixing bolt 4231 and a fixing washer 4232. The fixing bolt 4231 is installed on the workpiece fixing base plate 41 and passes through the long groove 4211. The fixing bolt 4231 presses the fixing washer 4232 onto the adaptive support frame 421. The long groove 4211 points towards the large circular machine workpiece, so as to realize the adjustment of the position of the adaptive support frame 421 during installation.

[0041] The foregoing has shown and described the basic principles and main features of the present invention, as well as its advantages. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope. All such changes and modifications fall within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
