Description

Technical Field

[0001] This utility model relates to the field of lathe workpiece processing technology, and in particular to an automated precision lathe workpiece clamping device. Background Technology

[0002] A search revealed that patent number CN220575340U discloses an automated clamping and processing device for CNC lathes, relating to the field of lathe clamping and processing. The device includes a processing table with support plates fixedly connected to both sides of its upper surface. A hollow plate is fixedly connected to the upper surface of both support plates, and a hydraulic cylinder is fixedly connected to the inner wall of the hollow plate. A brake motor is fixedly connected to the output end of the hydraulic cylinder. This invention uses a reciprocating motor to drive a gear that moves a rack inward, thereby clamping and fixing the workpiece to be processed. Anti-slip pads prevent loosening during processing. The hydraulic cylinder then pushes the processing head downward, and the brake motor further drives the processing head to process the workpiece. This eliminates the need for manual clamping, reducing workload and improving clamping efficiency, while also achieving automated clamping and processing.

[0003] The aforementioned patent uses two motors to drive two gears and racks to clamp the workpiece, bringing the clamping plates closer together. However, the two motors sometimes become asynchronous during operation, resulting in one clamping plate approaching one end of the workpiece's outer wall while the other has not yet made contact. This causes the workpiece to shift, affecting subsequent processing and increasing costs. Therefore, it is urgent to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automated precision lathe workpiece clamping device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automated precision lathe workpiece clamping device includes a machining table, a machining groove on the top of the machining table, clamping mechanisms for clamping workpieces at both ends of the machining groove, a first slot on one side of the machining table, and a synchronization mechanism for synchronizing the operation of the clamping mechanisms on the inner wall of the first slot, and a material collection mechanism at the bottom of the machining table.

[0007] The synchronization mechanism includes rotating rods rotatably connected to both ends of one side of the inner wall of the first slot. One end of the rotating rod is fixed with a first gear, and one end of the inner wall of the first slot is rotatably connected with a second gear, which meshes with the first gear. One end of the rotating rod is fixed with a synchronization wheel, and the outer wall of the second gear is fixed with another synchronization wheel. The outer walls of the two synchronization wheels are provided with matching synchronization belts. One end of the first slot away from the first gear is rotatably connected with a first sliding door.

[0008] As a further embodiment of this utility model, a mounting platform is fixed to the bottom of the inner wall of the first slot at the end away from the first gear. A motor is mounted on the top of the mounting platform, and the output shaft of the motor is fixedly connected to one end of one of the rotating rods. The two third gears can be driven to rotate simultaneously through a synchronous belt to prevent asynchronous phenomena.

[0009] As a further embodiment of this utility model, the clamping mechanism includes second slots opened at both ends of the processing groove. Trapezoidal grooves are provided on both sides of the inner wall of the two second slots, and a matching trapezoidal slider is slidably arranged inside the trapezoidal groove. The four trapezoidal sliders correspond to each other in pairs. The same fixing block is fixed on the side of the two trapezoidal sliders that are close to each other, and a clamping plate is fixed on the side of the two fixing blocks that are close to each other.

[0010] As a further embodiment of this utility model, each of the two fixed blocks is provided with a rack at its top, and the other end of the two rotating rods is fixed with a third gear, and the two third gears respectively mesh with one end of the two racks.

[0011] As a further embodiment of this utility model, an anti-slip pad is provided on the side of the two clamping plates that are close to each other, and a material collection mechanism is provided below the processing groove.

[0012] As a further embodiment of this utility model, the material collection mechanism includes a guide trough communicating with the processing groove, a perforated plate on the top of the guide trough, and a material collection box fixed at the bottom of the processing table. Waste materials can be collected into the material collection box through the guide trough.

[0013] As a further embodiment of this utility model, the material collection mechanism includes a guide trough communicating with the processing groove, a perforated plate on the top of the guide trough, and a material collection box fixed at the bottom of the processing table.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention utilizes a synchronous belt. When the motor drives one of the rotating rods to rotate, the rod drives one of the synchronous pulleys to rotate. This pulley, via the synchronous belt, drives another synchronous pulley to rotate. The second synchronous pulley drives a second gear to rotate, which meshes with the first gear and drives it to rotate as well. At this time, both rotating rods rotate simultaneously, one clockwise and the other counterclockwise. The rotating rods drive a third gear to rotate, which meshes with a rack and pinion, causing two fixed blocks to move closer together. The fixed blocks then move a clamping plate closer to the outer wall of the workpiece and clamp it. This effectively solves the problem mentioned in the background technology where, when two motors are used, they sometimes become asynchronous during operation. This can lead to one clamping plate approaching one end of the workpiece's outer wall while the other clamping plate has not yet made contact, causing the workpiece to shift and affecting subsequent processing, as well as increasing costs. This invention ensures the synchronous movement of the two clamping plates, avoiding the problem of workpiece shifting due to asynchrony, thereby improving processing accuracy and reducing reliance on multiple motors. This simplifies design, reduces system complexity, and minimizes potential failure points. Attached Figure Description

The outer walls of the two synchronization wheels 302 are provided with matching synchronization belts 3. One end of the first slot 104 away from the first gear 301 is rotatably connected with a first sliding door 103.

[0025] In this embodiment, a mounting platform 201 is fixed at the bottom of the inner wall of the first slot 104 away from the first gear 301. A motor 2 is mounted on the top of the mounting platform 201. The output shaft of the motor 2 is fixedly connected to one end of one of the rotating rods 304. The two third gears 505 can be driven to rotate simultaneously through the synchronous belt 3 to prevent asynchronous phenomena.

[0026] In this embodiment, the clamping mechanism includes second slots 506 at both ends of the processing groove 102. Trapezoidal grooves are provided on both sides of the inner wall of the two second slots 506, and a matching trapezoidal slider 504 is slidably provided inside the trapezoidal groove. The four trapezoidal sliders 504 correspond to each other in pairs. The same fixing block 502 is fixed on the side of the two trapezoidal sliders 504 that are close to each other, and a clamping plate 501 is fixed on the side of the two fixing blocks 502 that are close to each other.

[0027] In this embodiment, the top of each of the two fixed blocks 502 is provided with a rack 503, and the other end of the two rotating rods 304 is fixed with a third gear 505, and the two third gears 505 respectively mesh with one end of the two racks 503.

[0028] In this embodiment, anti-slip pads 5 are provided on the side of the two clamping plates 501 that are close to each other, and a material collection mechanism is provided below the processing groove 102.

[0029] In this embodiment, the material collection mechanism includes a guide trough 402 that communicates with the processing trough 102. The top of the guide trough 402 is provided with a perforated plate 401, and the bottom of the processing table 1 is fixed with a collection box 4.

[0030] In this embodiment, the material collection mechanism includes a guide trough 402 that communicates with the processing trough 102, a perforated plate 401 on the top of the guide trough 402, and a material collection box 4 fixed at the bottom of the processing table 1.

[0031] Working Principle: In use, the machining table 1 is equipped with a machining device for processing workpieces, which operates on the same principle as described in patent CN220575340U and will not be elaborated further here. The workpiece to be processed is placed inside the machining slot 102. Then, the motor 2 is activated, driving one of the rotating rods 304 to rotate. The rotating rod 304 drives one of the synchronous pulleys 302 to rotate. The synchronous pulley 302, via the synchronous belt 3, drives another synchronous pulley 302 to rotate. This other synchronous pulley 302 drives a second gear 303 to rotate. The second gear 303 meshes with a first gear 301, causing the first gear 301 to rotate. At this time, one of the rotating rods 304 rotates clockwise, and the other rotates counterclockwise. The two rotating rods 304 then drive a third gear 505 to rotate, which meshes with the rack 503. The two racks 503 will drive the two fixed blocks 502 to move closer to each other. The fixed blocks 502 will drive the trapezoidal slider 504 to slide in the trapezoidal groove. When the fixed blocks 502 move closer to each other, they will drive the two clamping plates 501 to move closer to the outer wall of the workpiece and clamp it. The anti-slip pad 5 will prevent the workpiece from sliding and shifting during the processing. The waste generated after processing will fall into the guide groove 402 through the hole of the sluice plate 401, and then slide from the guide groove 402 into the collection box 4. Opening the second pull door 403 can clean the waste inside the collection box 4. Opening the first pull door 103 can replace or repair the structure set inside the first slot 104.
