Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to an improved bed structure for a slant-back CNC lathe. Background Technology

[0002] Slant-bed CNC lathes are primarily used for high-precision, high-efficiency machining applications. Their unique design solves the problems of vibration, accuracy, and chip removal inherent in traditional flat-bed machine tools. They are suitable for machining precision parts, including straight cylinders, arcs, threads, grooves, and parts with complex contours, and are particularly suitable for machining parts with long axial dimensions or disc-shaped parts.

[0003] Currently, most slant-back CNC lathes on the market have a chip collection path on the bed, allowing the chips generated during machining to enter a through groove under the bed for later removal. However, as the chips accumulate, the through groove lacks a pressing mechanism, and the chips themselves are curved. When multiple curved chips accumulate inside the through groove, a large amount of space is occupied. After a period of operation, the chip collection path will become blocked, requiring repeated cleaning by the operator in a short period of time.

[0004] Therefore, this application proposes an improved bed structure for a slant-back CNC lathe. Utility Model Content

[0005] The purpose of this utility model is to provide an improved bed structure for a slanted back CNC lathe, so as to solve the problem mentioned in the background art. This technical solution can press the chips collected by chip removal to avoid chip overflow.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an improved bed structure for a slant-back CNC lathe, comprising a slant-back CNC lathe body, wherein a chip removal port is provided on the bed of the slant-back CNC lathe body, and a through groove is provided on the outer side of the slant-back CNC lathe body, wherein a partition is fixedly installed in the inner cavity of the through groove, and fixed plates are fixedly installed on both the left and right sides of the partition, and movable plates are movably installed on the rear sides of both fixed plates, wherein round shafts are fixedly installed through both movable plates, and the front sides of the two round shafts respectively pass through the corresponding fixed plates and are rotatably connected to the fixed plates, and a deflection component is provided on the front sides of both round shafts, and an abutment component is provided at the bottom of both movable plates.

[0007] Preferably, the deflection assembly includes two gears, which are respectively fixedly connected to the front end of a corresponding circular shaft and mesh with each other. One of the gears meshes with a gear on its outer side, and a motor is fixedly installed on the outer side of the gear.

[0008] Preferably, a fixing seat is fixedly installed on the outer wall of the motor, and the fixing seat is fixedly connected to the outer wall of the corresponding fixing plate.

[0009] Preferably, the abutment assembly includes multiple fixing members, each of which is fixedly connected to the outer wall of the partition. Each fixing member has an abutment strip movably installed in its inner cavity. A horizontal shaft is fixedly installed through the abutment strip. Both ends of the horizontal shaft pass through the outer wall of the fixing member and are fixedly connected to a fixing block. The horizontal shaft is movably connected to the outer wall of the fixing member. Two torsion springs are movably installed on the outer side of the horizontal shaft. Both ends of the torsion springs are fixedly connected to the outer wall of the fixing member and the outer wall of the fixing block, respectively.

[0010] Preferably, the abutment strip is inclined upwards, and a rubber sheet is installed on the top of the abutment strip.

[0011] Preferably, each of the two through slots is movably fitted with a cover, and each of the two covers is fitted with a transparent window.

[0012] Preferably, each of the two movable covers is equipped with two handles, which are arranged left and right.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Equipped with a motor, gear 1, and movable plate, when the main body of the slant-back CNC lathe generates chips during operation, the chips fall into the through groove through the chip discharge port. Before this, the motor needs to be driven to rotate gear 1, which in turn drives gear 2 to rotate. Gear 2 drives another adjacent meshing gear 2 to rotate, and the two gear 2 drives the corresponding round shafts to rotate. The round shafts drive the corresponding movable plates to deflect inside the through groove, causing the two movable plates to deflect from a horizontal state to an inclined state. At this time, the chip discharge port is open, and the chips inside can fall smoothly into the through groove, completing the chip collection.

[0014] 2. By setting up a movable plate, during the downward tilting movement of the movable plate, the motor repeatedly drives the movable plate to repeatedly rotate up and down around the circular axis. On the one hand, it can send the debris that falls to the top of the movable plate to a distant part of the channel. On the other hand, when debris accumulates at the bottom of the movable plate, it can press it down to compress the volume of the debris, which can reduce the number of times workers need to pick up materials and reduce the workload of workers.

Detailed Implementation

[0017] 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.

[0018] Please see Figures 1 to 5 This utility model provides a technical solution: an improved bed structure for a slant-back CNC lathe, including a slant-back CNC lathe body 1. A chip removal port 2 is provided on the bed of the slant-back CNC lathe body 1, and a through groove 3 is opened on the outer side of the slant-back CNC lathe body 1. A partition 7 is fixedly installed in the inner cavity of the through groove 3. Fixed plates 8 are fixedly installed on both the left and right sides of the partition 7. Movable plates 13 are movably installed on the rear side of both fixed plates 8. Round shafts 14 are fixedly installed through both movable plates 13. The front side of the two round shafts 14 passes through the corresponding fixed plates 8 and is rotatably connected to the fixed plates 8. A deflection component is provided on the front side of both round shafts 14, and an abutment component is provided at the bottom of both movable plates 13.

[0019] In this embodiment, during use, the workpiece is first precision machined using the main body 1 of the slant-back CNC lathe. During the machining process, a certain amount of chips are generated. The chips are discharged into the through groove 3 along the chip discharge port 2 for temporary storage. At this time, the deflection component is used to drive the movable plate 13 to deflect, so that the two movable plates 13 no longer block the bottom of the chip discharge port 2, allowing the chip discharge port 2 to be in an open state. Subsequently, the chips enter the through groove 3 along the chip discharge port 2, thereby collecting the chips.

[0020] As an optional implementation, the deflection assembly includes two gears 12, which are fixedly connected to the front end of the corresponding round shaft 14, and the two gears 12 mesh with each other. One of the gears 12 has a gear 11 meshing on its outer side, and a motor 9 is fixedly installed on the outer side of the gear 11.

[0021] In this embodiment, when the movable plate 13 is deflected, the motor 9 can be driven, causing the motor 9 to drive the gear 11 to rotate. The gear 11 drives the corresponding gear 12 to rotate, and the gear 12 drives the other adjacent meshing gear 12 to rotate. The two gears 12 drive the corresponding round shaft 14 to rotate, and the round shaft 14 drives the corresponding movable plate 13 to deflect inside the through groove 3, so that the two movable plates 13 deflect from the horizontal state to the inclined state, allowing the debris to fall onto the surface of the movable plate 13 and then enter the through groove 3 along the inclined movable plate 13 for temporary storage.

[0022] As more and more debris accumulates inside the channel 3, the repeated up-and-down deflection of the movable plate 13 can, on the one hand, press the debris downwards, thereby reducing the volume of debris and the number of times workers need to retrieve materials; on the other hand, when the movable plate 13 deflects upwards, it can throw the debris further away and send it into the depths of the channel 3 for temporary storage.

[0023] As an optional implementation, a fixing seat 10 is fixedly installed on the outer wall of the motor 9, and the fixing seat 10 is fixedly connected to the outer wall of the corresponding fixing plate 8.

[0024] In this embodiment, the fixing seat 10 enables the fixing of the motor 9 to the outer wall of the fixing plate 8, making the motor 9 more stable during subsequent operation and preventing loosening.

[0025] As an optional implementation, the abutment assembly includes multiple fasteners 15, each of which is fixedly connected to the outer wall of the partition 7. Each of the multiple fasteners 15 has an abutment strip 16 movably installed in its inner cavity. A horizontal shaft 18 is fixedly installed through the abutment strip 16. Both ends of the horizontal shaft 18 pass through the outer wall of the fastener 15 and are fixedly connected to a fixing block 19. The horizontal shaft 18 is movably connected to the outer wall of the fastener 15, and two torsion springs 20 are movably installed on the outer side of the horizontal shaft 18. Both ends of the torsion springs 20 are fixedly connected to the outer wall of the fastener 15 and the outer wall of the fixing block 19, respectively.

[0026] In this embodiment, during the downward deflection of the movable plate 13, it will come into contact with and collide with multiple adjacent abutment bars 16, causing the abutment bars 16 and the movable plate 13 to vibrate. This can promote the chip removal operation of the debris on the top of the movable plate 13. When the abutment bars 16 are pressed down, they will drive the horizontal shaft 18 to rotate synchronously. The horizontal shaft 18 will drive the fixed block 19 to rotate synchronously. The fixed block 19 will compress the corresponding torsion spring 20, using the torsion spring 20 to provide resistance and support for the abutment bars 16 and even the movable plate 13. When the movable plate 13 is reset upwards, the abutment bars 16 will reset synchronously under the elastic force of the torsion spring 20.

[0027] As an optional implementation, the abutment strip 16 is inclined upwards, and a rubber sheet 17 is installed on the top of the abutment strip 16.

[0028] In this embodiment, the rubber sheet 17 provides a buffering effect to a certain extent during use, thereby increasing the service life of the contact strip 16 and preventing it from loosening.

[0029] As an optional implementation, a movable cover 4 is movably installed on the front side of each of the two through slots 3, and a transparent window 5 is embedded in each of the two movable covers 4.

[0030] In this embodiment, during use, the transparent window 5 allows workers to easily view the amount of debris inside the channel 3, and when it is necessary to remove the debris, the movable cover 4 is opened to carry out the debris removal operation.

[0031] As an optional implementation, each of the two movable covers 4 is equipped with two handles 6, which are arranged left and right.

[0032] In this embodiment, the two handles 6 make it convenient for staff to apply force to the movable cover 4 to remove it for subsequent work.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
