[0001] This utility model relates to the field of multi-station turntables, and more particularly to a multi-station turntable for a chamfering machine tool. Background Technology

[0002] A multi-station turntable is a widely used automated equipment component in industrial production. It enables the rapid transfer and processing of workpieces between multiple stations. It is a common type of multi-station turntable installed on chamfering machine tools and is quite common in existing technologies.

[0003] Existing technologies, such as the utility model with publication number CN219057552U, disclose a multi-station turntable fixture. This patent employs a worktable, a rotary drive assembly mounted on the worktable, and a turntable mounted on the rotary drive assembly. The turntable and the worktable surfaces are arranged parallel to each other at intervals. The rotary drive assembly drives the turntable to rotate. Multiple support brackets are provided on the edge of the turntable. Each support bracket includes a support frame, a support seat, and a pair of locking blocks, all located within the support frame. The support seat has a receiving groove for accommodating cylindrical battery cells. The pair of locking blocks are used to engage the support seat with the support frame. The multi-station turntable fixture provided by this utility model, by setting a turntable on the rotary drive assembly and multiple support brackets on the turntable, allows the turntable to quickly switch the positions of the support brackets through rotation, achieving rapid switching between multiple workstations. It is reusable, has a simple overall structure, is easy to operate, and is suitable for equipment with multiple testing and processing devices.

[0004] The inventors have found in the prior art that when personnel need to chamfer workpieces of other sizes, they need to use tools to replace the limiting device. During the replacement process, personnel also need to manually rotate the tool repeatedly to fix the limiting device firmly or disassemble it. Because this operation method is very cumbersome and wastes personnel's working time, it leads to the problem of low work efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, when personnel need to chamfer workpieces of other sizes, they need to use tools to change the limiting device. This operation is very cumbersome and wastes personnel's working time, which leads to low work efficiency. Therefore, a multi-station turntable for chamfering machine tool is proposed.

[0006] To solve the above technical problems, this utility model provides a multi-station turntable for a chamfering machine tool, comprising: a support column and a replacement structure. A fixed plate and a turntable body are mounted on the upper surface of the support column. Several limiting devices are mounted on the upper surface of the turntable body via the replacement structure. Two cylinders are mounted on the upper surface of the fixed plate. The replacement structure is provided on the lower surface of the turntable body. The replacement structure includes several connecting grooves and several positioning plates. The connecting grooves are all formed on the turntable body. The positioning plates are fixedly connected to the turntable body. Connecting plates are slidably connected to the inner walls of the connecting grooves. The connecting plates are grouped in pairs. Each group of connecting plates is fixedly connected to a limiting device. A positioning groove is formed on the inner wall of the connecting plate. Two fixed plates are fixedly connected to both sides of the positioning plate. Limiting grooves are formed on the inner walls of the fixed plates. The inner wall of the limiting groove is slidably connected to a connecting block, and the inner wall of the limiting groove is fixedly connected to a limiting rod. A spring is sleeved on the arc surface of the limiting rod, and the two ends of the spring are fixedly connected to the limiting groove and the connecting block, respectively. The limiting rod is slidably connected to the connecting block. A limiting plate is fixedly connected to the side of the two connecting blocks that are close to each other. The limiting plate is slidably connected to the positioning groove. An inclined plate is fixedly connected to the side of the limiting plate away from the turntable body. An installation plate is fixedly connected to the side of the positioning plate that is close to the support column.

The extrusion plate is an isosceles trapezoid and abuts against the two inclined plates. A rotating block is fixedly connected to the end of the threaded rod that is away from the installation plate.

[0007] The effect achieved by the above components is that when personnel need to replace the limiting device to limit workpieces of other sizes, they can rotate the rotating block and move the pressing plate away from the rotating block. At this time, the spring rebounds and causes the limiting plate to slide out of the inner wall of the positioning groove, which makes it convenient for personnel to quickly replace the limiting device and thus improves the replacement efficiency.

[0008] Preferably, two positioning rods are fixedly connected to the side of the extrusion plate near the mounting plate, and the two positioning rods are slidably connected to the mounting plate.

[0009] The effect achieved by the above components is that the positioning rod can limit the extrusion plate and improve the stability of the extrusion plate during movement.

[0010] Preferably, the inner wall of the rotating block is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly provided on the arc surface of the rotating block.

[0011] The effect achieved by the above components is that the anti-slip groove can increase the friction between the operator's hand and the rotating block, and can prevent the operator from slipping during the rotation of the rotating block.

[0012] Preferably, a guide plate is fixedly connected to the side of the connecting plate away from the limiting device.

[0013] The effect achieved by the above components is that the guide plate can guide the connecting plate, making it convenient for personnel to quickly slide the connecting plate into the inner wall of the connecting groove.

[0014] Preferably, the limiting rod is a stainless steel rod, and the cross-section of the limiting rod is circular.

[0015] The effect achieved by the above components is that the stainless steel rod has high strength and good wear resistance, which can prevent the limit rod from deforming during short-term use.

[0016] Preferably, the upper surface of the fixed plate is provided with a protective structure, the protective structure including four auxiliary plates, the four auxiliary plates being fixedly connected to the fixed plate, the inner wall of the auxiliary plates having an installation groove, the inner wall of the installation groove being slidably connected to an adjusting plate, the four adjusting plates being in pairs, the upper surface of one pair of adjusting plates being fixedly connected to a glass plate, the side of the glass plate near the cylinder output end being fixedly connected to a baffle, the inner wall of the baffle having a connecting hole, the connecting hole being slidably connected to the arc surface of the cylinder output end, the side of the glass plate away from the baffle being fixedly connected to an auxiliary rod, the arc surface of the auxiliary rod being rotatably connected to an adjusting block, the inner wall of the adjusting block being threadedly connected to a lead screw, the end of the lead screw away from the cylinder being fixedly connected to a moving block.

[0017] The effect achieved by the above-mentioned components is that when personnel need to chamfer the workpiece, they can first move the glass plate to fit the surface of the cylinder, and then rotate the moving block to make the protective pad abut against the cylinder, thereby preventing the coolant from contacting the cylinder and improving the service life of the cylinder.

[0018] Preferably, a protective pad is fixedly connected to the end of the lead screw near the cylinder, and the protective pad abuts against the cylinder.

[0019] The effect achieved by the above components is that the protective pad can protect the cylinder and prevent the lead screw from directly contacting the cylinder.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figure 1 The present invention provides a multi-station turntable for a chamfering machine tool, comprising: a support column 1 and a replacement structure 3. A fixed plate 6 and a turntable body 2 are mounted on the upper surface of the support column 1. Several limiting devices 7 are mounted on the upper surface of the turntable body 2 by means of the replacement structure 3. Two cylinders 5 are mounted on the upper surface of the fixed plate 6. The replacement structure 3 is provided on the lower surface of the turntable body 2. A protective structure 4 is provided on the upper surface of the fixed plate 6.

[0033] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The replacement structure 3 includes several connecting grooves 301 and several positioning plates 302. The connecting grooves 301 are all formed on the turntable body 2, and the positioning plates 302 are fixedly connected to the turntable body 2. Connecting plates 311 are slidably connected to the inner wall of the connecting grooves 301. The connecting plates 311 are arranged in pairs, and each pair of connecting plates 311 is fixedly connected to the limiting device 7. Positioning grooves 303 are formed on the inner wall of the connecting plates 311. Two fixing plates 319 are fixedly connected to both sides of the positioning plates 302. Limiting grooves 305 are formed on the inner wall of the fixing plates 319. Connecting blocks 317 are slidably connected to the inner wall of the limiting grooves 305. Limiting rods 307 are fixedly connected to the inner wall of the limiting grooves 305. Springs 306 are sleeved on the arc surface of the limiting rods 307, and the two ends of the springs 306 are respectively connected to the limiting grooves 305 and the connecting blocks 317. The limiting rod 307 is slidably connected to the connecting block 317. A limiting plate 310 is fixedly connected to the side of the two connecting blocks 317 that are close to each other. The limiting plate 310 is slidably connected to the positioning groove 303. An inclined plate 312 is fixedly connected to the side of the limiting plate 310 away from the turntable body 2. An mounting plate 308 is fixedly connected to the side of the positioning plate 302 that is close to the support column 1. A connecting plate 309 is fixedly connected to the side of the positioning plate 302 that is away from the support column 1. A threaded rod 316 is rotatably connected to the inner wall of the connecting plate 309. An extrusion plate 313 is threadedly connected to the arc surface of the threaded rod 316. The threaded rod 316 is rotatably connected to the mounting plate 308. The extrusion plate 313 is an isosceles trapezoid and abuts against the two inclined plates 312. A rotating block 314 is fixedly connected to the end of the threaded rod 316 that is away from the mounting plate 308. When personnel need to replace the limiting device 7 to limit workpieces of other sizes, they can rotate the rotating block 314, causing the pressing plate 313 to move away from the rotating block 314. At this time, the spring 306 rebounds, causing the limiting plate 310 to slide out of the inner wall of the positioning groove 303. This allows for convenient and quick replacement of the limiting device 7, thereby improving the replacement efficiency. Two positioning rods 318 are fixedly connected to the side of the pressing plate 313 near the mounting plate 308, and the two positioning rods 318 are slidably connected to the mounting plate 308. The positioning rods 318 can limit the pressing plate 313 and improve the stability of the pressing plate 313 during movement. The inner wall of the rotating block 314 is provided with several anti-slip grooves 315, which are evenly distributed on the arc surface of the rotating block 314. The anti-slip groove 315 increases the friction between the operator's hand and the rotating block 314, preventing slippage during rotation. A guide plate 304 is fixedly connected to the side of the connecting plate 311 away from the limiting device 7. The guide plate 304 guides the connecting plate 311, allowing the operator to quickly slide it into the inner wall of the connecting groove 301. The limiting rod 307 is made of stainless steel and has a circular cross-section.The stainless steel rod has high strength and good wear resistance, which can prevent the limit rod 307 from deforming during short-term use.

[0034] In the embodiments of this utility model, please refer to Figure 4 and Figure 5 The protective structure 4 includes four auxiliary plates 402, which are fixedly connected to the fixed plate 6. The inner wall of the auxiliary plates 402 is provided with an installation groove 411. An adjustment plate 403 is slidably connected to the inner wall of the installation groove 411. The four adjustment plates 403 are in pairs. A glass plate 401 is fixedly connected to the upper surface of a pair of adjustment plates 403. A baffle 404 is fixedly connected to the side of the glass plate 401 near the output end of the cylinder 5. A connecting hole 405 is provided on the inner wall of the baffle 404. The connecting hole 405 is slidably connected to the arc surface of the output end of the cylinder 5. An auxiliary rod 406 is fixedly connected to the side of the glass plate 401 away from the baffle 404. An adjustment block 407 is rotatably connected to the arc surface of the auxiliary rod 406. A lead screw 409 is threadedly connected to the inner wall of the adjustment block 407. A moving block 408 is fixedly connected to the end of the lead screw 409 away from the cylinder 5. When chamfering is required on a workpiece, the operator first moves the glass plate 401 to fit it onto the surface of the cylinder 5. Then, the operator rotates the moving block 408 to bring the protective pad 410 into contact with the cylinder 5, thus preventing coolant from contacting the cylinder 5 and extending its service life. The protective pad 410 is fixedly connected to the end of the lead screw 409 near the cylinder 5, and it abuts against the cylinder 5. The protective pad 410 protects the cylinder 5 and prevents direct contact between the lead screw 409 and the cylinder 5.

[0035] The working principle of the multi-station turntable of the chamfering machine tool provided by this utility model is as follows: When the workpiece needs to be chamfered, the workpiece is moved by the conveying device on the chamfering machine tool. Then, the workpiece is moved onto the limiting device 7 by the mechanical gripper. Then, the rotating device inside the support column 1 is activated to rotate the turntable body 2. The limiting device 7 drives the workpiece to rotate until the workpiece rotates to a suitable position. At this time, the workpiece is in front of the output end of the cylinder 5. Then, the cylinder 5 is activated again. The output end of the cylinder 5 squeezes the workpiece to fix it stably on the limiting device 7. Then, the chamfering device on the chamfering machine tool is used to chamfer the workpiece. During the process, the workpiece and chamfering device are cooled by coolant. After chamfering is completed, the workpiece can be moved out of the limiting device 7 by a mechanical gripper. When personnel need to chamfer workpieces of other sizes, they can first rotate the rotating block 314. The anti-slip groove 315 on the inner wall of the rotating block 314 increases the friction between the personnel's hands and the rotating block 314, preventing slippage during rotation. Then, the rotating block 314 drives the threaded rod 316 to rotate, which in turn drives the pressing plate 313 to move away from the rotating block 314. The pressing plate 313 then drives the two positioning rods 318 to move away from the rotating block 314. The extrusion plate 313 moves in the direction of 4, and the positioning rod 318 slides on the inner wall of the mounting plate 308. The positioning rod 318 can limit the extrusion plate 313, which can improve the stability of the extrusion plate 313 during movement. At this time, the spring 306 rebounds, and the spring 306 drives the connecting block 317 to move closer to the positioning plate 302. The connecting block 317 slides on the arc surface of the limiting rod 307. The two connecting blocks 317 also drive the limiting plate 310 to move closer to the positioning plate 302. Then the limiting plate 310 drives the inclined plate 312 to move closer to the positioning plate 302. When the extrusion plate 313 moves to the appropriate position, the limiting plate 312... 10 will slide out of the inner wall of the positioning groove 303, and then the personnel will move the limiting device 7. The limiting device 7 will drive the two connecting plates 311 to move away from the connecting groove 301. The connecting plates 311 will drive the guide plate 304 to move away from the connecting groove 301. The guide plate 304 can guide the connecting plates 311, which can facilitate the personnel to quickly slide the connecting plates 311 into the inner wall of the connecting groove 301 until the guide plate 304 completely slides out of the inner wall of the connecting groove 301. The limiting rod 307 is a stainless steel rod. The stainless steel rod has high strength and good wear resistance, which can prevent the limiting rod 307 from deforming during short-term use.

[0036] Additionally, when personnel need to chamfer the workpiece on the limiting device 7, they can first move the glass plate 401. The glass plate 401 drives the baffle 404, the two adjusting plates 403, and the auxiliary rod 406 to move closer to the cylinder 5. The auxiliary rod 406 drives the lead screw 409 to move closer to the cylinder 5. The lead screw 409 drives the adjusting block 407 and the protective pad 410 to move closer to the cylinder 5 until the arc surface of the output end of the cylinder 5 slides into the inner wall of the connecting hole 405, and the adjusting plate 403 slides into the mounting groove 41. The inner wall of cylinder 1 is rotated until the baffle 404 is close to the cylinder 5 and abuts against the cylinder 5. Then, the operator rotates the adjusting block 407 so that the adjusting block 407 is rotated to the side of the cylinder 5 away from the baffle 404. Then, the operator rotates the moving block 408, which drives the lead screw 409 to rotate. The lead screw 409 drives the protective pad 410 to move towards the cylinder 5 until the protective pad 410 abuts against the cylinder 5. The protective pad 410 can protect the cylinder 5 and prevent the lead screw 409 from directly contacting the cylinder 5.

[0037] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
