Description

Technical Field

[0001] This utility model belongs to the technical field of five-axis machining centers, specifically relating to a fixture for a five-axis machining center. Background Technology

[0002] Machining centers evolved from CNC milling machines. The biggest difference between machining centers and CNC milling machines lies in the ability of machining centers to automatically change machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed in a single setup via an automatic tool changer, achieving multiple machining functions. Fixtures are needed for auxiliary machining. A search reveals application number "CN201920693348.1" disclosing "a fixture for a machining center," which describes "the partitions on both sides of the clamping block guide the gas to the bottom of the table slot to blow away cutting chips. The filter screen prevents the chips from bouncing into the air duct of the clamping block and causing blockages during the blowing process." While it's true that using partitions on both sides of the clamping block to guide the gas to the bottom of the table slot to blow away cutting chips, and the filter screen does prevent the chips from bouncing into the air duct of the clamping block and causing blockages during the blowing process, the above-mentioned document still has the following problems in actual use:

[0003] In actual use, there are few actual clamping points, which can easily lead to unstable clamping. Furthermore, the angle cannot be adjusted during use, which can cause the machining process to easily collide with the spindle.

[0004] Therefore, providing a tooling that can achieve stable clamping and convenient angle adjustment is of great practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a fixture for a five-axis machining center, which aims to solve the above-mentioned technical problems.

[0006] This utility model provides a fixture for a five-axis machining center, including a support plate, a stabilizing clamping assembly, and an adjusting assembly.

[0007] The top of the support plate is provided with a connecting plate;

A clamping platform is mounted in the middle of the support ring. A sliding groove is mounted inside the clamping platform. A movable seat is slidably connected inside the sliding groove. A clamping frame is mounted on the top of each of the movable seats.

[0009] The adjustment assembly includes a base corresponding to the bottom of the support plate. Several support heads are fixedly connected to the top side of the base. Each of the support heads is hinged to a hinge seat. Several electric cylinders are provided on the bottom inner wall of the base. The output shaft ends of the electric cylinders are all provided with fixed heads through the base. Rotary rods are rotatably connected inside two of the fixed heads. A support bar is rotatably connected in the middle of the rotary rods. Support plates are provided at both ends of the rotary rods.

[0010] In one embodiment of this utility model, the bottom of the clamping platform is provided with a plurality of auxiliary grooves, the bottom of each of the plurality of movable seats is provided with a connecting rod, the outer wall of each of the plurality of connecting rods is slidably connected to the inclined groove and the auxiliary groove, and the bottom of each of the plurality of connecting rods is provided with an anti-drop ring.

[0033] Example

[0034] Please see Figure 1 - Figure 4 A fixture for a five-axis machining center includes a support plate 100, a stabilizing clamping assembly 200, and an adjusting assembly 300.

[0035] Please refer to the details. Figure 1 A connecting plate 110 is provided on the top of the support plate 100.

[0036] Please see Figure 3 - Figure 4 The stabilizing clamping assembly 200 includes a torque motor 210 disposed on the top of the connecting plate 110. A turntable 220 is disposed at the output shaft end of the torque motor 210. The turntable 220 has several inclined grooves inside. A fixing ring 230 is disposed on the top outer wall of the connecting plate 110. A support ring 240 is disposed on the top of the fixing ring 230. A clamping platform 250 is disposed in the middle of the support ring 240. A number of sliding grooves are disposed inside the clamping platform 250. A movable seat 260 is slidably connected inside the sliding grooves. A clamping frame 270 is disposed on the top of each of the movable seats 260.

[0037] In one specific embodiment, when a workpiece needs to be clamped, the controller turns on the torque motor 210, causing it to rotate and drive the top turntable 220 to rotate. The rotation of the turntable 220 causes the drive connecting rod 400 to slide in the inclined groove, which in turn causes the connecting rod 400 to move the movable seat 260. The movable seat 260 slides in the sliding groove, which in turn causes the clamping frame 270 to move, thus clamping the workpiece. By using multiple clamping frames 270, multi-point clamping is achieved, making the clamping more stable.

[0038] Please see Figure 1 - Figure 2The adjustment assembly 300 includes a base 310 correspondingly disposed at the bottom of the support plate 100. Several support heads 320 are fixedly connected to one side of the top of the base 310. Each of the support heads 320 is hinged to a hinge seat 330. Several electric cylinders 340 are disposed at the bottom of the inner wall of the base 310. The output shaft ends of the electric cylinders 340 are all disposed with fixed heads 350 through the base 310. Rotary rods 360 are rotatably connected inside the two fixed heads 350. A support bar 370 is rotatably connected in the middle of the rotary rod 360. Support plates 380 are disposed at both ends of the rotary rod 360.

[0039] In one specific embodiment, the electric cylinder 340 allows the user to easily adjust the angle when needed. The controller activates the electric cylinder 340 and the servo motor 800. The output axis of the electric cylinder 340 moves upward, causing the fixed head 350 to move. The fixed head 350, through the rotating rod 360, support bar 370, and support plate 380, causes the support plate 100 to tilt up via the hinge seat 330, thereby raising the angle. The servo motor 800 then drives the base 310 to rotate, which in turn causes the top part of the base to rotate, thereby adjusting the direction and thus achieving the angle adjustment of the clamped workpiece for processing.

[0040] Please see Figure 4 The bottom of the clamping table 250 is provided with several auxiliary grooves, and the bottom of several movable seats 260 is provided with connecting rods 400. The outer walls of several connecting rods 400 are slidably connected to the inclined grooves and auxiliary grooves, and the bottom of several connecting rods 400 is provided with anti-drop rings 500.

[0041] In one specific embodiment, the anti-drop ring 500 ensures that the connecting rod 400 is stably positioned within the inclined groove and auxiliary groove during use, preventing it from falling out and getting stuck, thus improving stability.

[0042] Please see Figure 2 An auxiliary ring 600 is rotatably connected to the bottom of the base 310. A fixed seat 700 is provided at the bottom of the auxiliary ring 600, and a servo motor 800 is provided at the bottom of the inner wall of the fixed seat 700.

[0043] In one specific embodiment, the auxiliary ring 600 is provided to assist the base 310 in rotating, making it more stable during rotation and avoiding wobbling.

[0044] Please see Figure 2 The output shaft end of the servo motor 800 passes through the fixed seat 700 and is fixedly connected to the base 310. The tops of several hinge seats 330 are fixedly connected to the support plate 100.

[0045] In one specific embodiment, the fixed base 700 provides convenient support for the whole and protects the servo motor 800, making it more stable during use.

[0046] Please see Figure 1 The tops of the support bar 370 and the two support plates 380 are fixedly connected to the support plate 100.

[0047] In one specific embodiment, the provided support plate 100 facilitates the support of the top part during use, thereby enabling stable clamping of the workpiece and improving stability.

[0048] Please see Figure 2 Both the support plate 100 and the base 310 are made of titanium alloy, and a controller is provided at one end of the base 310.

[0049] In one specific embodiment, the titanium alloy provided allows for greater stability of the support plate 100 and base 310 during use, thanks to the robust and durable properties of the titanium alloy.

[0050] Please see Figure 1 - Figure 4 The torque motor 210, servo motor 800 and electric cylinder 340 are all electrically connected to the controller, and the controller is electrically connected to an external power supply.

[0051] In one specific embodiment, a controller is provided to facilitate power supply control of electrical equipment, enabling the equipment to be powered on when needed, thus avoiding situations where power cannot be supplied when power is required.

[0052] In use, the torque motor 210 is first activated by the controller when the workpiece needs to be clamped. The torque motor 210 rotates, causing the top turntable 220 to rotate. The rotation of the turntable 220 causes the drive connecting rod 400 to slide within the inclined groove, which in turn moves the movable seat 260. The movable seat 260 then slides within the sliding groove, moving the clamping frame 270 to clamp the workpiece. Multiple clamping frames 270 achieve multi-point clamping, making the clamping more stable. Then... The electric cylinder 340 is provided so that when the angle needs to be adjusted, the controller will activate the electric cylinder 340 and the servo motor 800. The output axis of the electric cylinder 340 moves upward, driving the fixed head 350 to move. The fixed head 350, through the rotating rod 360, the support bar 370 and the support plate 380, causes the support plate 100 to tilt up through the hinge seat 330, and finally raises the angle. The servo motor 800 will drive the base 310 to rotate. The rotation of the base 310 will drive the top part of it to rotate, thereby adjusting the direction, so as to realize the angle adjustment of the clamped workpiece for processing.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
