[0001] This application relates to the field of machine tool equipment technology, and in particular to a limiting mechanism, a processing device and processing equipment. Background Technology

[0002] With the continuous advancement of machine tool technology and the increasing diversification of machine tool applications, the requirements for machine tools are becoming increasingly stringent. The clutch is a key component of an automobile parking system; this component consists of a gear shaft and a clutch outer hub that are laser-welded and then precision-machined.

[0003] In laser welding, a limiting device is often used to fix the clutch to prevent it from moving during welding, thereby improving welding accuracy. However, when the limiting device fixes the workpiece, the specific position of the clutch is not precise, which may cause misalignment at the weld joint of the clutch, reducing welding accuracy and making it difficult to meet the requirements of high-precision welding quality. Utility Model Content

[0022] The slide mechanism is connected to the limiting mechanism and can drive the limiting mechanism to move;

[0023] The machining mechanism, located on one side of the slide mechanism, is capable of machining the clutch unit that is limited in the limiting mechanism.

[0024] In one embodiment, the slide mechanism includes:

Through the combined action of the lifting component and the pressing component, the position of the clutch unit can be restricted, ensuring precise positioning of the clutch unit and thus guaranteeing the accuracy of subsequent processing, thereby meeting the higher requirements of the clutch unit processing.

[0077] like Figure 9As shown, the processing components include an operating table 401, a laser 402, a chiller 404, an electrical main control cabinet 405, a regulated power supply 406, a dust removal system 407, a welding chamber 409, and a laser welding head 410. The moving components include a robot control cabinet 403 and a multi-axis robot 408. The operating table 401 is installed outside the welding chamber 409. The clutch torque clamping fixture is installed on the infeed slide mechanism, which is installed through the welding chamber 409, with one end outside and one end inside. The laser welding head 410 is installed at the end of the 6-axis robot 408, which is installed inside the welding chamber 409. The laser 402, robot control cabinet 403, chiller 404, electrical main control cabinet 405, regulated power supply 406, and dust removal system 407 are distributed around the periphery of the welding chamber 409.

[0078] Taking one workstation as an example (the other three workstations are similar), the operator places the clutch hub 102 on the upper surface of the fixture base 202 included in the positioning seat device, and inserts the gear shaft 102 into the center hole of the fixture base 20; the operator starts the operating table 401 and turns on the automatic mode; the third servo motor 304 included in the slide mechanism drives the transmission screw pair 306, the slide plate 302, the slide rail pair 303, and the positioning seat device in sequence to enter the welding room 409.

[0079] The clutch torque clamping fixture contains a second servo motor 209 that sequentially drives an electric cylinder 208, a turntable mounting plate 210, a crossed roller bearing 205, a reducer 206, a second servo motor 209, a turntable mounting plate 210, a first reducer mounting plate 212, a baffle 213, a reducer adjusting block 214, a first spur gear 215, a turntable bearing mounting plate 216, a fixture base plate 217, a second guide rail mounting plate 218, a guide sleeve 219, and a first guide rail mounting plate 220.

The clamping pressure is transmitted to the torque sensor, and the torque sensor transmits the pressure signal to the second servo motor 209 to stop it.

[0080] The first servo motor 207 sequentially drives the rotation of the first reducer 206, the second spur gear 223, the first spur gear 215, the gear connecting plate 221, the crossed roller bearing 205, the fixture base plate 217, the guide sleeve 219, the guide shaft 237, the guide shaft support 241, the follower clamping mounting plate 238, the safety pin 236, the first clamping plate 242, the second clamping plate 243, the clutch outer hub 101, and the gear shaft 102.

[0081] After the clutch outer hub 101 starts rotating, the 6-axis robot 408 drags the laser welding head 410 to move above the clutch outer hub 101, and the laser welding head 410 emits laser to perform welding; after welding is completed, the first servo motor 207 stops rotating in sequence; the 6-axis robot 408 drags the laser welding head 410 away; the cylinder 235 drives the rotating positioning block 230 to extend into the corresponding slot of the follow-up clamping mounting plate 238, and the guide sleeve 219, guide shaft 237, guide shaft support 241, and follow-up clamping mounting plate 238 are fixed and positioned.

[0082] The second servo motor 209 drives the electric cylinder 208, which in turn drives the turntable mounting plate 210 and the cross roller bearing 205, reducer 206, second servo motor 209, turntable mounting plate 210, first reducer mounting plate 212, baffle 213, reducer adjusting block 214, first spur gear 215, turntable bearing mounting plate 216, fixture base plate 217, second guide rail mounting plate 218, guide sleeve 219, first guide rail mounting plate 220, gear connecting plate 221, turntable support plate 222, second spur gear 223, guide rail side support plate 224, third reducer mounting plate 225, slider 226, second reducer mounting plate 227, and lifting mounting plate 228 to descend vertically along the guide rail 211 in the direction away from the top frame device.

[0083] The clutch outer hub 101 separates from the second clamping plate 243; the third servo motor 304 included in the slide mechanism drives the transmission screw pair 306, which in turn drives the slide plate 302 along the slide rail pair 303 to drive the positioning seat device out of the welding chamber 409, and the workpiece is manually removed. One work cycle is completed.

[0084] This application also provides a processing device, which includes the limiting mechanism in the above embodiments.

[0085] The division of the various modules in the above-described limiting mechanism is only for illustrative purposes. In other embodiments, the limiting mechanism can be divided into different modules as needed to complete all or part of the functions of the above-described limiting mechanism.

[0086] The limiting mechanism, processing device, and processing equipment provided in the above embodiments, when processing the clutch unit, have a positioning component approaching and abutting against the clutch unit to provide installation support for the clutch unit. A lifting component located on one side of the positioning component (as below) approaches and abuts against the lower surface of the positioning component along the height direction of the lifting component to drive the positioning component to perform a lifting movement. A pressing component located on the other side of the positioning component (as above) approaches and abuts against the upper surface of the positioning component along the height direction of the pressing component to drive the positioning component to perform a pressing movement. Through the cooperation of the pressing action of the lifting component and the pressing action of the pressing component, the position of the clutch unit can be restricted, thereby ensuring the precise positioning of the clutch unit and ensuring the accuracy of the subsequent processing, thus meeting the higher requirements of the clutch unit processing process.

[0087] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
