Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, specifically to an automatic feeding multi-station machining equipment. Background Technology

[0002] Machining is a crucial part of manufacturing, referring to the process of altering the shape, dimensions, or properties of a workpiece using mechanical equipment. This process primarily includes two methods: cutting and pressure processing, involving multiple technological steps such as casting, forging, stamping, welding, and assembly. In machining, the workpiece is first designed, followed by machining preparation, such as selecting cutting tools and fixtures. Next, CNC programs control the machine tool to perform precise machining operations, while cutting fluid is used for cooling and lubrication to ensure machining quality and efficiency. After machining, the workpiece must undergo quality inspection to ensure it meets the predetermined accuracy and quality requirements.

[0003] In current industrial production processes, the vast majority of machining equipment still operates using an independent workstation mode. In this mode, each workpiece or group of workpieces must be processed on the clamping device before the machine stops. Subsequently, the operator needs to manually place new workpieces onto the clamping device before the machine can continue processing. This manual loading method results in relatively low efficiency throughout the entire machining process. Therefore, an automated loading multi-station machining equipment is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding multi-station machining equipment to solve the problem of low processing efficiency in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a turntable body, a drive assembly at the bottom of the turntable body, a material unloading chute on one side of the turntable body, a workstation body mounted on the turntable body, a clamping mechanism on the workstation body, the clamping mechanism including auxiliary hydraulic cylinders fixedly mounted on both sides of the workstation body, a clamping plate fixedly mounted at the output end of the auxiliary hydraulic cylinders, a main hydraulic cylinder at the bottom of the workstation body, a piston movably mounted inside the main hydraulic cylinder, a screw jack connected to the piston, and a material unloading mechanism connected to the workstation body.

[0006] Preferably, an oil supply pipe is provided between the main oil cylinder and the auxiliary oil cylinder, and a drive shaft is connected to the screw jack, with a first clutch provided on the drive shaft.

[0007] Preferably, the bottom of the workstation body is provided with a retainer, and the screw jack is fixedly installed at the bottom of the workstation body through the retainer.

[0008] Preferably, one end of the oil delivery pipeline is connected to the auxiliary oil cylinder, the other end of the oil delivery pipeline is connected to the main oil cylinder, the clamping plate is movably installed in the workstation body through the auxiliary oil cylinder, and the output end of the screw jack is fixed on the piston.

[0009] Preferably, the unloading mechanism includes a positioning guide rod fixedly installed at the bottom of the workstation body, a sliding frame slidably installed on the positioning guide rod, an unloading push plate fixedly installed on the sliding frame, a lead screw connected to the sliding frame, a second clutch provided on the lead screw, a drive motor fixedly installed inside the workstation body, the output end of the drive motor connected to a transmission shaft, a linkage shaft provided between the transmission shaft and the lead screw, and helical gears provided on the transmission shaft, the lead screw, and the linkage shaft.

[0010] Preferably, the output end of the drive motor is provided with a coupling, and the transmission shaft is fixedly installed at the output end of the drive motor through the coupling.

[0011] Preferably, the sliding frame is slidably mounted on the workstation body via a positioning guide rod, and the unloading push plate is slidably mounted on the workstation body via the sliding frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, the operation of the drive motor rotates the transmission shaft, thereby driving the operation of the screw jack. The movement of the screw jack causes the piston to move into the main cylinder, squeezing hydraulic oil into the auxiliary cylinder. The transfer of hydraulic oil causes the auxiliary cylinder to push the clamping plate forward, achieving workpiece clamping within the workstation body. Subsequently, the rotation control of the turntable body automatically positions the workpiece below the processing instrument, facilitating continuous processing and improving processing efficiency.

[0014] 2. In the retracted state of the screw jack, this application enables a clamping plate release mechanism. After the clamping plate is released, the drive motor starts, thereby driving the linkage shaft to rotate. The rotation of the linkage shaft is transmitted to the screw, causing it to rotate. As the screw rotates, the sliding frame slides along the positioning guide rod, and through the action of the unloading push plate, pushes the workpiece out of the workstation body. The pushed-out workpiece then slides down the unloading chute, thus completing the automatic unloading process. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for an automatic feeding multi-station machining equipment, including a turntable body 1, a drive component 3 at the bottom of the turntable body 1, a discharge chute 2 on one side of the turntable body 1, a station body 4 mounted on the turntable body 1, a clamping mechanism 5 on the station body 4, and a discharge mechanism 6 connected to the station body 4. Through the cooperation of the clamping mechanism 5 and the turntable body 1, the workpiece can be automatically moved under the machining equipment for convenient continuous processing, and the discharge mechanism 6 can realize automatic discharge.

[0023] like Figure 3 and Figure 4 As shown, the clamping mechanism 5 includes auxiliary oil cylinders 502 fixedly installed on both sides of the workstation body 4. A clamping plate 501 is fixedly installed at the output end of the auxiliary oil cylinder 502. A main oil cylinder 504 is provided at the bottom of the workstation body 4. A piston 505 is movably installed in the main oil cylinder 504. A screw jack 507 is connected to the piston 505. An oil supply pipe 503 is provided between the main oil cylinder 504 and the auxiliary oil cylinder 502. A drive shaft 506 is connected to the screw jack 507. A first clutch 508 is provided on the drive shaft 506. A retainer is provided at the bottom of the workstation body 4. The screw jack 507 is fixedly installed at the bottom of the workstation body 4 through the retainer.

[0024] Specifically, the drive motor 607 drives the transmission shaft 506 to rotate. During rotation, the transmission shaft 506 further drives the screw jack 507. As the screw jack 507 operates, it causes the piston 505 to move into the main cylinder 504. This movement of the piston 505 compresses the hydraulic oil in the main cylinder 504, which is then forced into the auxiliary cylinder 502. Under the action of the hydraulic oil, the auxiliary cylinder 502 pushes the clamping plate 501 forward, thus firmly clamping the workpiece in the appropriate position on the workstation body 4. After the workpiece is clamped, the rotation of the turntable body 1 can be controlled. The rotation of the turntable body 1 allows the workpiece to automatically move below the processing machine, facilitating continuous processing.

[0025] like Figure 3 and Figure 5 As shown, the unloading mechanism 6 includes a positioning guide rod 601 fixedly installed at the bottom of the workstation body 4. A sliding frame 603 is slidably installed on the positioning guide rod 601. An unloading push plate 602 is fixedly installed on the sliding frame 603. A lead screw 604 is connected to the sliding frame 603. A second clutch 605 is provided on the lead screw 604. A drive motor 607 is fixedly installed inside the workstation body 4. The output end of the drive motor 607 is connected to the transmission shaft 506. A linkage shaft 608 is provided between the transmission shaft 506 and the lead screw 604. Helical gears 606 are provided on the transmission shaft 506, the lead screw 604, and the linkage shaft 608. A coupling is provided at the output end of the drive motor 607. The transmission shaft 506 is fixedly installed at the output end of the drive motor 607 through the coupling.

[0026] Specifically, when the screw jack 507 is retracted, it effectively controls the release of the clamping plate 501. Once the clamping plate 501 is released, the drive motor 607 is allowed to start working, thereby driving the linkage shaft 608 to rotate. As the linkage shaft 608 rotates, it further drives the screw 604 to rotate accordingly. The rotation of the screw 604 causes the sliding frame 603 to slide along the positioning guide rod 601. The sliding of the sliding frame 603 allows the unloading push plate 602 to push out the workpiece located in the workstation body 4. The pushed-out workpiece can then smoothly slide down the unloading chute 2, thus completing the automatic unloading process.

[0027] Working principle: During use, multiple sets of processing instruments can be set above the turntable body 1. Then, the workpiece can be placed in the workstation body 4. After the workpiece is placed in the workstation body 4, the drive motor 607 drives the transmission shaft 506 to rotate. After the transmission shaft 506 rotates, it drives the screw jack 507 to operate. After the screw jack 507 operates, it drives the piston 505 to move into the main oil cylinder 504, thereby squeezing the hydraulic oil in the main oil cylinder 504 into the auxiliary oil cylinder 502. This causes the auxiliary oil cylinder 502 to push the clamping plate 501 forward, clamping the workpiece in the workstation body 4. Then, the turntable body 1 can be controlled to rotate, so that the workpiece moves under the processing instruments for continuous processing. After processing is completed, the screw jack 507 can be retracted. After the screw jack 507 is retracted, the clamping plate 501 can be released. After the clamping plate 501 is released, the drive motor 607 can drive the linkage shaft 608 to rotate. After the linkage shaft 608 rotates, it will drive the screw 604 to rotate. After the screw 604 rotates, the sliding frame 603 will slide along the positioning guide rod 601, thereby using the unloading push plate 602 to push out the workpiece in the workstation body 4. The pushed-out workpiece can slide down along the unloading chute 2 to realize automatic unloading.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
