Description

Technical Field

[0001] This utility model relates to the field of CNC lathes, specifically a material receiving device for CNC lathes. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other machining operations.

[0003] After a CNC lathe cuts a workpiece, it needs to collect the cut workpiece using a receiving device. However, most existing receiving devices are single-collection structures. After a certain amount of material is collected, processing needs to be stopped for transfer, which is not convenient for continuous processing and affects processing efficiency. Therefore, those skilled in the art have provided a receiving device for a CNC lathe to solve the problems mentioned in the background art. Utility Model Content

Two mounting rods are fixedly installed at the bottom of the receiving hopper. The two ends of the mounting rods are fixedly installed between the two mounting brackets, so that the mounting brackets can drive the eight receiving hoppers to change positions. When the motor runs, it drives the turntable and the disc to rotate synchronously. The turntable can rotate along the arc surface of the backing plate to provide positioning support for the adjusting ring. The disc drives the teeth to make circumferential motion. When the teeth contact the internal gear ring, they drive the internal gear ring to rotate slightly, which can drive the mounting brackets to rotate synchronously and change the positions of the eight receiving hoppers. When the opening of the receiving hopper is facing downward, the workpiece can be poured into the receiving box, which achieves the effect of repeated receiving.

[0007] Preferably, the feeding mechanism includes a housing fixedly installed on the top of the receiving box. Two symmetrically distributed guide plates are fixedly connected to the top of the housing. The guide plates have an inclined structure to facilitate the workpiece sliding into the receiving hopper. An opening for the mounting plate is provided on the outer side of the housing. Arc-shaped grooves for workpiece feeding are provided on both inner walls of the housing to facilitate workpiece feeding. Rubber pads are fixedly connected to the surface of the guide plates to provide vibration damping for falling workpieces. Workpieces on CNC lathes can enter the receiving hopper through the rubber pads on the two guide plates, which can provide vibration damping for the workpieces and improve the safety of receiving materials.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses an adjustment mechanism to make the motor drive the turntable and the disc rotate synchronously. The turntable can rotate along the arc surface of the backing plate to provide positioning support for the adjustment ring, so that the teeth make circumferential motion. When the teeth contact the inner tooth ring, they drive the inner tooth ring to rotate slightly, which can replace the position of the eight receiving hoppers on the mounting frame. When the opening of the receiving hopper is facing down, the workpiece can be poured into the receiving box, thus achieving the effect of repeated receiving, which is convenient for assembly line processing.

[0025] 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.

[0026] Example 1

[0027] Please see Figure 1 and Figure 2 The figure shows a receiving device for a CNC lathe, including a receiving box 1 and two mounting plates 2 symmetrically installed on the top of the receiving box 1. It also includes: a positioning cylinder 5 disposed between the two mounting plates 2, with eight receiving hoppers 6 arranged in a ring at equal intervals on the outer side of the positioning cylinder 5. The eight receiving hoppers 6 are used for interchangeable receiving of workpieces from the CNC lathe. Adjacent receiving hoppers 6 contact each other, improving the compactness of the receiving hoppers 6. Four equally spaced moving wheels 7 are fixedly connected to the bottom of the receiving box 1 for easy movement and adjustment; an adjusting mechanism 3 for changing the position of the receiving hoppers 6, installed on the top of the receiving box 1; and a feeding mechanism 4 for guiding the feeding of the receiving hoppers 6, installed on the outer side of the mounting plate 2.

[0028] Please see Figures 2-6The adjusting mechanism 3 shown in the figure includes a motor 301 installed on the top of the receiving box 1. The motor 301 is fixedly installed on the outside of the mounting plate 2. The output end of the motor 301 slides through the surface of the mounting plate 2 and is fixedly connected to a turntable 302. An internal gear ring 303 is provided on the outside of the turntable 302. An adjusting ring 304 is fixedly connected to the outside of the internal gear ring 303. Eight abutments 305 corresponding to the positions of the eight receiving hoppers 6 are fixedly connected to the inside of the adjusting ring 304. The outside of the abutments 305 contacts the outside of the turntable 302. The contact surface between the abutments 305 and the turntable 302 is an arc-shaped structure. The turntable 302 can move along the arc surface of the abutments 305. An opening is provided on the surface of the turntable 302 to facilitate docking with the abutments 305. A disc 306 is fixedly connected to the side of the turntable 302 away from the motor 301. A tooth 307 that mates with the internal gear ring 303 is fixedly connected to the outer side of the disc 306. The tooth 307 on the disc 306 can mate with the internal gear ring 303, causing the internal gear ring 303 to rotate slightly. Two symmetrically distributed mounting brackets 308 are fixedly connected to the outer side of the positioning cylinder 5. The internal gear ring 303 is fixedly installed on the outer side of the mounting bracket 308, so that when the internal gear ring 303 rotates, it can drive the mounting bracket 308 to rotate synchronously. Two mounting rods 309 are fixedly installed at the bottom of the receiving hopper 6. The two ends of the mounting rods 309 are fixedly installed between the two mounting brackets 308, so that the mounting brackets 308 can drive the eight receiving hoppers 6 to change positions.

[0029] Motor 301 continuously drives turntable 302 and disc 306 to rotate synchronously. Turntable 302 can rotate along the arc surface of back plate 305 to provide positioning support for adjusting ring 304. Disc 306 drives tooth 307 to make circular motion. When tooth 307 contacts internal tooth ring 303, it cooperates with the tooth groove of internal tooth ring 303, causing the mounting bracket 308 on internal tooth ring 303 to rotate slightly along the outside of positioning cylinder 5, changing the position of eight receiving hoppers 6. When the opening of receiving hopper 6 is facing down, the workpiece can be poured into receiving box 1. Thus, the eight receiving hoppers 6 make intermittent circular motion to receive and unload workpieces, thereby achieving the effect of repeated receiving, which is suitable for assembly line production.

[0030] Please see Figure 1 and Figure 2 The feeding mechanism 4 shown in the figure includes a housing 401 fixedly installed on the top of the receiving box 1. Two symmetrically distributed guide plates 402 are fixedly connected to the top of the housing 401. The guide plates 402 have an inclined structure to facilitate the workpiece sliding into the receiving hopper 6. An opening for the mounting plate 2 is provided on the outer side of the housing 401. Arc-shaped grooves for workpiece feeding are provided on both inner walls of the housing 401 to facilitate workpiece feeding. A rubber pad 403 is fixedly connected to the surface of the guide plate 402 to provide vibration damping for the falling workpiece.

[0031] When a workpiece is unloaded from a CNC lathe, it can roll into the receiving hopper 6 through the rubber pads 403 on the two guide plates 402. The elasticity of the rubber pads 403 provides vibration damping for the workpiece, improving the safety of receiving the material. When the receiving hopper 6 rotates downwards, it can enter the receiving box 1 through the arc-shaped groove of the outer shell 401, preventing the workpiece from getting stuck between the outer shell 401 and the receiving hopper 6, thus achieving the effect of safe receiving and unloading.

[0032] The working principle for facilitating repeated receiving of workpieces on CNC lathes is as follows: First, the user moves the receiving box 1 to the feeding point of the CNC lathe and starts the motor 301. The workpiece unloaded by the CNC lathe rolls into the receiving hopper 6 via the rubber pads 403 on the two guide plates 402. At this time, the motor 301 drives the turntable 302 and the disc 306 to rotate continuously. The turntable 302 rotates along the arc surface of the abutment plate 305, providing positioning support for the adjusting ring 304. Simultaneously, the disc 306 drives the gear 307 to perform circumferential motion. When the gear... When tooth 307 contacts the internal gear ring 303, it engages with the tooth groove of the internal gear ring 303, causing the mounting bracket 308 on the internal gear ring 303 to rotate slightly along the outside of the positioning cylinder 5, changing the position of the eight receiving hoppers 6. As the motor 301 continues to run, the opening of the receiving hopper 6 storing the workpiece faces downward, pouring the workpiece into the receiving box 1. Thus, the eight receiving hoppers 6 make intermittent circular motions to receive and unload the workpiece, thereby achieving the effect of repeated receiving, which is suitable for assembly line production.

[0033] Example 2

[0034] Please see Figures 1-3 This embodiment further illustrates Example 1. In the figure, positioning rings 8 are fixedly connected to both ends of the positioning cylinder 5. The positioning rings 8 are in contact with the outer side of the mounting plate 2, which facilitates the installation of the positioning cylinder 5. A guide rod 9 is slidably installed on the inner side of the positioning cylinder 5, which cooperates with the moving wheel 7 to facilitate the adjustment of the receiving position. Two symmetrically distributed support plates 10 are fixedly connected between the two sides of the receiving box 1 and the mounting plate 2 to improve the stability of the mounting plate 2. A side plate 11 is fixedly connected to the arc surface of the abutment plate 305. The side plate 11 is in contact with the outer side of the turntable 302 to prevent the position of the abutment plate 305 and the turntable 302 from shifting.

[0035] In this embodiment, the user can insert the guide rod 9 into the inside of the positioning cylinder 5, push the receiving box 1 to make the moving wheel 7 move along the ground, and adjust the position of receiving material so as to make corresponding adjustments according to the feeding position of the CNC lathe.

[0036] Example 3

[0037] Please see Figure 2 and Figure 6This embodiment further illustrates other embodiments. In the figure, the inner walls on both sides of the receiving hopper 6 are symmetrical inclined structures, which facilitates the feeding of workpieces. The receiving box 1 is equipped with a pull cabinet 12. The outer side of the receiving box 1 has an opening for the pull cabinet 12 to be limited and slid, which is used to store and retrieve workpieces. The opening of the pull cabinet 12 is an inclined structure to prevent workpieces from getting stuck at the top opening of the pull cabinet 12.

[0038] In this embodiment, the user pulls the drawer 12 along the inside of the receiving box 1 to take out the drawer 12, which makes it easier to reuse the workpiece after receiving it. The workpiece can roll in along the inclined surface of the receiving hopper 6 to prevent the workpiece from getting stuck at the opening, thus making it easier to pick up the material.
