Description

Technical Field

[0001] The present invention relates to the field of machining, and particularly to a multi-station loading machine tool for circular workpieces. Background Art

[0002] Circular workpieces are applied in many fields such as mechanical manufacturing, automotive industry, electrical equipment, and construction. At present, the processing of circular workpieces is made through metal processing techniques such as stamping, cutting, or grinding. In some complex production processes, different workshops may be responsible for different processing steps. For example, after the stamping process of circular workpieces is completed in Workshop No. 1, it needs to be transported to Workshop No. 2 for drilling, installation, or subsequent finishing. This division of labor is to ensure the efficiency and specialization of each process. When the existing loading machine tool for circular workpieces is loading, it is necessary to stack the circular workpieces first and then load them. In the actual production process, a unloading machine tool needs to be installed at the last process in Workshop No. 1, and a loading machine tool needs to be installed at the initial process in Workshop No. 2. The circular workpieces are unloaded stack by stack from the unloading machine tool in Workshop No. 1 and then placed stack by stack on the loading machine tool in Workshop No. 2. The entire loading and unloading process is relatively cumbersome and requires a lot of time for stacking and sorting. In view of this, the present invention provides a multi-station loading machine tool for circular workpieces to solve the above-mentioned technical problems. Summary of the Invention

An inclined surface that cooperates with the fixing pin is provided on the U-shaped block. Meshing teeth for locking the incomplete gear are provided on both the bottom surface of the incomplete gear and the top surface of the second disc.

[0008] As an improvement to the above solution, the first driving assembly includes a first motor and a rotating shaft. The first motor is installed inside the machine tool body, and a rotating shaft is fixedly connected to the output shaft of the first motor. The top end of the rotating shaft is fixedly connected to the rotating shaft of the turntable.

[0009] As an improvement to the above solution, the second driving assembly includes a driving box, a large gear, a small gear, a second motor, and a second gear. The driving box is fixedly connected to the bottom end of the rotating shaft.

[0012] As an improvement to the above solution, it further includes a baffle. The baffle is fixedly connected to the bottom surface of the large gear, and the top surface of the baffle is in contact with the bottom surface of the incomplete gear, so that a gap is provided between the incomplete gear and the top surface of the second disc.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The present invention is provided with components such as a loading fixture. During use, due to the stepped groove provided on the inner diameter of the circular ring block, the loading fixture can be conveniently used on the blanking machine tool in the first workshop and the loading machine tool in the second workshop. In this way, the handling of circular workpieces between different workshops becomes simpler, reducing the operation difficulty.

Then, the incomplete gear drives the toothed ring to rotate. Then, the toothed ring drives the first gear to rotate through meshing transmission. Then, the first gear drives the rotating shaft to rotate. Then, the rotating shaft drives the connecting rod to rotate. Then, the connecting rod drives the limiting rod to move. Then, the limiting rod moves towards the center of the first disc with the arc groove as the guide, so as to adapt to the diameters of different circular workpieces. At the same time, the limiting rod can also align the circular workpiece with the center point of the first disc. If the circular workpieces are stacked together, the limiting rod can also tidy up the stacked circular workpieces and prevent the circular workpieces from shifting during loading.

[0016] 3. The present invention is provided with components such as a magnetic separator. When the top block drives the circular workpiece to move to the top of the limiting rod, the magnetic separator can adsorb the circular workpiece through magnetic force and separate the circular workpieces during this process, so as to avoid the phenomenon of circular workpieces sticking together, thereby improving the efficiency of the loading process.

Detailed implementation manners

[0028] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrating the present application and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually those in conventional experiments.

[0029] A multi-station loading machine tool for circular workpieces, as Figures 1 - 10As shown in the figure, it includes a machine tool body 101. A turntable 102 is rotatably connected to the top surface of the machine tool body 101. The turntable 102 is circular. The turntable 102 is driven by a first drive assembly to rotate. Specifically, the first drive assembly includes a first motor 201 and a rotating shaft 202. The first motor 201 is installed in the machine tool body 101. A rotating shaft 202 is fixedly connected to the output shaft of the first motor 201. The top end of the rotating shaft 202 is fixedly connected to the rotating shaft of the turntable 102. Six circular grooves 1021 are circumferentially arranged on the turntable 102 around the center point of the turntable 102. An annular block 103 is fixedly connected in the circular groove 1021. The outer diameter of the annular block 103 is the same as that of the circular groove 1021. A stepped groove 1031 is arranged on the inner diameter of the annular block 103. A loading fixture is movably connected to the stepped groove 1031. Specifically, the loading fixture includes a first disc 104, a bending block 106, a second disc 107, a rotating shaft 108, a connecting rod 109, a limiting rod 110, a top block 111, a first gear 301, a toothed ring 302 and an incomplete gear 308. The first disc 104 is movably connected to the stepped groove 1031. The first disc 104 fits with the stepped groove 1031. The bottom surface of the first disc 104 is fixedly connected to the second disc 107 through the bending block 106. Three rotating shafts 108 are circumferentially rotatably connected to the top surface of the second disc 107 with the center point of the circular groove 1021 as the center. One end of a connecting rod 109 is fixedly connected to the rotating shaft 108. The other end of the connecting rod 109 is fixedly connected to the limiting rod 110. The top end of the rotating shaft 108 is fixedly connected to the first gear 301. A toothed ring 302 is rotatably connected to the top surface of the second disc 107. The toothed ring 302 meshes with the three first gears 301. An incomplete gear 308 is connected to the outer side wall of the toothed ring 302 through a sliding key. The incomplete gear 308 is driven by a second drive assembly to rotate. An arc groove 1042 for facilitating the movement of the limiting rod 110 is arranged on the first disc 104. One end of the arc groove 1042 is close to the center of the first disc 104, and the other end is close to the edge of the first disc 104. A top block 111 is arranged on the top surface of the first disc 104. The top block 111 is in a "person" shape. Three straight grooves 1111 are arranged on the top block 111. The straight grooves 1111 are sleeved on the limiting rod 110. Circular workpieces are placed on the top surface of the top block 111. One or more workpieces can be stacked together. The top block 111 is driven by a third drive assembly to slide up and down.

[0030] Furthermore, a positioning groove 1041 is provided on the first disk 104, and a U-shaped block 105 that cooperates with the positioning groove 1041 is fixedly connected to the bottom surface of the annular block 103, so that the loading fixture cannot rotate self-rotationally, and thus the loading fixture can be fixed in the horizontal direction; there are two sets of this device. When in use, one set is used for the blanking machine tool in Workshop No. 1, and the other set is used for the loading machine tool in Workshop No. 2. The specific operation is as follows: First, use the blanking machine tool in Workshop No. 1 to stack circular workpieces together. Place the circular workpieces on the top surface of the top block 111. One or more can be placed and stacked together. Then, drive the incomplete gear 308 to rotate through the second driving component. Then, the incomplete gear 308 drives the gear ring 302 to rotate. Then, the gear ring 302 drives the first gear 301 to rotate through meshing transmission. Then, the first gear 301 drives the rotating shaft 108 to rotate. Then, the rotating shaft 108 drives the connecting rod 109 to rotate. Then, the connecting rod 109 drives the limiting rod 110 to move. Then, the limiting rod 110 approaches each other towards the center of the first disk 104 with the arc groove 1042 as the guide. Thus, it can adapt to the diameters of different circular workpieces. At the same time, the limiting rod 110 can also align the circular workpiece with the center point of the first disk 104. If the circular workpieces are stacked together, the limiting rod 110 can also tidy up the stacked circular workpieces and prevent the circular workpieces from shifting during loading. In this way, the circular workpieces are placed on the loading fixture, and the operation of placing the circular workpieces is completed. Then, the loaded loading fixture is transported to the loading machine tool in Workshop No. 2 by a manipulator or manually using a handling device. Align the positioning groove 1041 with the U-shaped block 105, and directly place the loaded loading fixture into the circular groove 1021. Since a stepped groove 1031 is provided on the inner diameter of the annular block 103, the loading fixture can be directly placed into the circular groove 1021. Then, drive the top block 111 through the third driving component. Then, the top block 111 slides upward. Then, the top block 111 drives the circular workpiece to move upward. Then, the top block 111 can drive the circular workpiece to move to the top of the limiting rod 110 so that the next process can be automatically loaded. After the circular workpiece in one of the circular grooves 1021 is loaded, start the first motor 201. Then, the output shaft of the first motor 201 drives the rotating shaft 202 to rotate. Then, the rotating shaft 202 drives the turntable 102 to rotate. Thus, continuous loading can be achieved.

[0031] Furthermore, the loading fixture further includes a magnetic separator 601. The magnetic separator 601 is installed at the top end of the limiting rod 110. When the top block 111 drives the circular workpiece to move to the top of the limiting rod 110, the magnetic separator 601 can adsorb the circular workpiece through magnetic force and separate the circular workpieces during this process. In this way, the phenomenon of circular workpieces sticking together can be avoided, thereby improving the efficiency of the loading process.

[0032] Further, the loading fixture further includes a locking component for locking the incomplete gear 308. The locking component includes a concave block 501, a wedge block 502, an elastic member 503, a fixing pin 504, and a fixing plate 505. The bottom surface of the first disc 104 is fixedly connected with the concave block 501. The concave block 501 is slidably connected with the wedge block 502. The wedge block 502 is made of rubber, and the bottom surface of the wedge block 502 is coated with a high-friction lubricant. An elastic member 503 is arranged between the wedge block 502 and the concave block 501. The elastic member 503 is specifically a spring. Initially, the elastic member 503 is compressed. The bottom surface of the wedge block 502 is fixedly connected with the fixing plate 505. An activity groove 5051 for the U-shaped block 105 to move is arranged on the fixing plate 505. A fixing pin 504 is fixedly connected in the activity groove 5051. An inclined surface 1051 matching with the fixing pin 504 is arranged on the U-shaped block 105. Meshing teeth 506 for locking the incomplete gear 308 are arranged on the bottom surface of the incomplete gear 308 and the top surface of the second disc 107. Specifically: When the loaded loading fixture is transported to the loading machine tool in the second workshop by a manipulator or manually using a handling device, the locking component is designed to prevent the incomplete gear 308 from rotating and thus causing the limit rod 110 to move. Since the incomplete gear 308 is connected to the outer side wall of the gear ring 302 through a sliding key, when the loading fixture moves upward, the incomplete gear 308 will move downward under the influence of gravity and contact the top surface of the second disc 107, so that the meshing teeth 506 on the bottom surface of the incomplete gear 308 are engaged with the meshing teeth 506 on the top surface of the second disc 107, which can prevent the incomplete gear 308 from rotating self, and thus prevent the limit rod 110 from moving. At the same time, since the U-shaped block 105 no longer restricts the fixing plate 505, the elastic member 503 resets, driving the wedge block 502 to move towards the incomplete gear 308, and the bottom surface of the wedge block 502 contacts the top surface of the incomplete gear 308, so as to prevent the incomplete gear 308 from moving up and down during transportation. When placing the loading fixture, that is, placing it on the loading machine tool in the second workshop, align the positioning groove 1041 with the U-shaped block 105 and directly put the loaded loading fixture into the circular groove 1021. Since the inclined surface 1051 matching with the fixing pin 504 is arranged on the U-shaped block 105, under the action of the U-shaped block 105, the fixing pin 504 drives the fixing plate 505 and the wedge block 502 to move away from the incomplete gear 308, and the wedge block 502 compresses the elastic member 503, so that the elastic member 503 stores elastic potential energy. In this way, the transfer work is completed, and the operation is simple and convenient.

[0033] Specifically, the second driving component includes a driving box 303, a large gear 307, a small gear 306, a second motor 304 and a second gear 305. The bottom end of the rotating shaft 202 is fixedly connected with the driving box 303. The second motor 304 is installed in the driving box 303. The output shaft of the second motor 304 is fixedly connected with the second gear 305. The top end of the driving box 303 is rotatably connected with the small gear 306. The small gear 306 meshes with the second gear 305. The top surface of the small gear 306 is fixedly connected with the large gear 307. The large gear 307 is rotatably connected with the bottom surface of the turntable 102. Both the large gear 307 and the small gear 306 are sleeved on the rotating shaft 202. The incomplete gear 308 meshes with the large gear 307. It further includes a baffle 604. The bottom surface of the large gear 307 is fixedly connected with the baffle 604. The top surface of the baffle 604 is in contact with the bottom surface of the incomplete gear 308, so that there is a gap between the incomplete gear 308 and the top surface of the second disc 107. Specifically: start the second motor 304. The output shaft of the second motor 304 drives the second gear 305 to rotate. Then, the second gear 305 drives the small gear 306 to rotate through meshing transmission. Then, the small gear 306 drives the large gear 307 to rotate. The large gear 307 drives the incomplete gear 308 to rotate through meshing transmission. Then, the limiting rod 110 can be moved to align the circular workpiece with the center point of the first disc 104. At the same time, due to the setting of the baffle 604, when placing the loading fixture, the baffle 604 will support the incomplete gear 308 upward, so that there is a gap between the incomplete gear 308 and the top surface of the second disc 107. Then, the meshing teeth 506 on the bottom surface of the incomplete gear 308 are separated from the meshing teeth 506 on the top surface of the second disc 107. And when the loading fixture is lifted, the incomplete gear 308 will slide downward and cooperate with the wedge block 502 and the meshing teeth 506 to achieve locking and limiting.

[0034] Specifically, the third driving component includes a mounting seat 401 and an electric telescopic rod 402. Lifting holes 1001 are provided at the centers of the first disc 104 and the second disc 107. Two mounting seats 401 are circumferentially arranged in the machine tool body 101 around the center point of the turntable 102. The two mounting seats 401 are symmetrically arranged. The electric telescopic rod 402 is installed on the mounting seat 401. The telescopic rod of the electric telescopic rod 402 is coaxially arranged with the lifting hole 1001. When the telescopic rod of the electric telescopic rod 402 extends, it abuts against the bottom surface of the top block 111. It can be seen from this that when feeding is required, start the electric telescopic rod 402. Then, the telescopic rod of the electric telescopic rod 402 extends upward. The telescopic rod of the electric telescopic rod 402 pops out upward from the lifting hole 1001. Then, the telescopic rod of the electric telescopic rod 402 abuts against the top block 111, so that the top block 111 moves upward. Then, the circular workpiece can be moved to the top of the limiting rod 110 for feeding.

[0035] Furthermore, it further includes a fixed seat 602 and a camera 603. The fixed seat 602 is installed on the top surface of the machine tool body 101, and the camera 603 for detecting the feeding situation is installed on the fixed seat 602, so that the specific situation of the feeding machine tool can be conveniently monitored.

[0036] The above embodiments are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made based on the content of the claims of the present invention should be included within the scope of the claims of the present invention.
