Description

Technical Field

[0001] This utility model relates to the field of machine tool parts processing technology, and in particular to a punching device for processing machine tool parts. Background Technology

[0002] Punching is a common and critical machining process in the machining of machine tool parts. From gears and bushings in mechanical transmission components to frames and brackets in structural support components, many types of machine tool parts need to be punched to achieve the connection, assembly and construction of functional structures between components. The performance of the punching device has become one of the key factors determining the machining level of machine tool parts.

[0003] Application No. 202323117161.2 discloses a punching device for processing metal parts, including a base. Support columns are fixedly connected to the four corners of the upper surface of the base. Guide plates are fixedly connected to the upper surface of the base between two of the support columns. Support plates are fixedly connected to the base via several support columns and several guide plates. Connecting plates are fixedly connected to both sides of the upper surface of the support plates. This application uses an electric push rod to simultaneously move the two fixed frames in opposite directions to adjust the distance between them. Then, by rotating a knob, a threaded rod is rotated, causing the clamping plate to slide along the inner wall of the fixed frame. The fixed frames on both sides clamp and fix the parts, aligning the metal parts to be punched with the drill bit. This achieves precise positioning and punching of parts of different sizes, demonstrating the practicality of the device.

[0004] The above solution has shortcomings in use. After punching a single part, it is necessary to release the fixed part after punching and then re-fix the unpunched part. It is also impossible to complete the continuous punching operation of the part, which greatly reduces the punching efficiency of the part. To address this, we provide a punching device for machining machine tool parts. Utility Model Content

[0005] This utility model provides a punching device for machining machine tool parts. When punching a single part, the operator can simultaneously fix the next part. After the punching is completed, the part can move away from the punching area. At the same time, the fixed but not punched parts will move to the punching area, thereby realizing continuous punching and further improving punching efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] First Embodiment

[0032] As attached Figure 1 To be continued Figure 4 As shown: A punching device for machining machine tool parts includes a base plate 1 and a rotating part fixing assembly 2, which is disposed above the base plate 1. The assembly includes a set of upright plates 201 disposed on the upper surface of the base plate 1, a rotating rod 202 rotatably connected to the set of upright plates 201, a carrier plate 203 arranged in a ring outside the rotating rod 202, and a groove 204 formed on each carrier plate 203. The carrier plate 203 can be used to place the part to be punched, and the waste generated during punching can be discharged from the groove 204.

[0033] A collection box 5 is placed on top of the base plate 1, and the collection box 5 is directly below the trough 204. The collection box 5 can be used to collect the waste generated by punching, which is convenient for operators to handle the waste in a centralized manner. Positioning plates 6 are set on both the left and right sides of the collection box 5. The bottom surface of each positioning plate 6 is connected to the upper surface of the base plate 1. The positioning plates 6 can stabilize the position of the collection box 5, so that the collection box 5 is stable below the trough 204 to collect waste.

[0034] The clamping structure for fixing parts is provided on each carrier plate 203. The clamping structure of the rotating part fixing assembly 2 includes a set of electric push rods 205 installed on one side of each carrier plate 203. Each electric push rod 205 has an L-shaped pressure plate 206 installed at its telescopic end. The retraction of the electric push rod 205 can drive the L-shaped pressure plate 206 to move closer to the carrier plate 203, and the carrier plate 203 will gradually fix the parts.

[0035] A drive structure for rotating the carrier plate 203 is installed on one of the upright plates 201. The drive structure of the rotating part fixing assembly 2 includes a motor 207 mounted on the front of one of the upright plates 201. A pinion 208 is installed at the output end of the motor 207. A large gear 209 meshes above the pinion 208. The back of the large gear 209 is connected to the front end of the rotating rod 202. When the motor 207 is working, the pinion 208, driven by the motor 207, will drive the large gear 209 and the rotating rod 202 to rotate. At the same time, the carrier plate 203 will drive the part to be punched to deflect until the part to be punched deflects. When the punch is positioned directly below the punch head 303, punching can begin. As the carrier plate 203 deflects, the operator can remove the punched parts and secure the unpunched parts during the punching process, further improving the efficiency of punching. The large gear 209 and the small gear 208 are both fitted with a protective shell 210. The back of the protective shell 210 is connected to the front of one of the upright plates 201, and the protective shell 210 has heat dissipation holes. The protective shell 210 can be used to shield and protect the small gear 208 and the large gear 209, further extending their service life.

[0036] Second Embodiment

[0037] As attached Figure 1 With appendix Figure 5 As shown: The punching structure 3 is set above the base plate 1 and is used to punch parts above the carrier plate 203. The punching structure 3 includes a hanging plate 301 installed on the upper surface of the base plate 1. A hydraulic push rod 302 is installed on the bottom surface of the top of the hanging plate 301. A punching head 303 is detachably installed on the telescopic end of the hydraulic push rod 302. The extension of the hydraulic push rod 302 can push the punching head 303 down, so that the punching head 303 can be lowered to perform punching operation on the parts.

[0038] Third Embodiment

[0039] As attached Figure 1 With appendix Figure 6As shown: Stabilizing component 4, disposed above the base plate 1, is used to ensure the stability of the carrier plate 203 under impact pressure. Stabilizing component 4 includes a set of rotating shafts 401 rotatably connected to the upper surface of the base plate 1. Each rotating shaft 401 has a limiting plate 402 fixedly connected to its top end. When the rotating shafts 401 rotate, they can rotate the limiting plate 402 above the carrier plate 203. When the carrier plate 203 on the other side is subjected to impact pressure, the limiting plate 402 can stabilize it, ensuring that the carrier plate 203 remains horizontal and preventing deflection under impact pressure. This further ensures the positional accuracy and stability during punching of parts. Stabilizing component 4 also includes... A motor 403 is mounted on the upper surface of the base plate 1. A first gear 404 is mounted on the output end of the motor 403. A toothed belt 405 is sleeved on the outside of the first gear 404. A set of second gears 406 is sleeved inside the toothed belt 405. The inner wall of each second gear 406 is connected to the outer surface of the rotating shaft 401. With the operation of the motor 403, the first gear 404 and the second gear 406 form a transmission connection through the toothed belt 405. The second gears 406 and the rotating shaft 401 will rotate synchronously, thereby synchronously driving the two limiting plates 402 to rotate, further improving the efficiency of stabilizing the carrier plate 203.

[0040] The outer surfaces of the two rotating shafts 401 are rotatably connected to a U-shaped plate 407. The bottom end of the U-shaped plate 407 is connected to the upper surface of the base plate 1. The U-shaped plate 407 can be used to connect and reinforce the rotating shafts 401, further ensuring that the limiting plate 402 provides reliable support for the carrier plate 203 when it is subjected to impact pressure.

[0041] Working principle: First, the operator places the parts to be punched under the carrier plate 203 one by one. Then, the electric push rod 205 is activated to retract, and the L-shaped pressure plate 206 moves towards the carrier plate 203, thus pressing the parts between the carrier plate 203 and the L-shaped pressure plate 206 until all the parts to be punched are fixed on the carrier plate 203. Then, the motor 207 starts to work. The small gear 208, driven by the motor 207, drives the large gear 209 and the rotating rod 202 to rotate. At the same time, the carrier plate 203 drives the parts to be punched to deflect until the parts to be punched are directly under the punching head 303. At this time, the motor 403 is activated. The first belt gear 404 is connected to the second belt gear 405 through the toothed belt 405. A transmission connection is formed at 06. The second gear 406 and the rotating shaft 401 rotate synchronously. The limiting plate 402 fixed on the rotating shaft 401 will quickly rotate to above the carrier plate 203. Then, the hydraulic push rod 302 is extended. The hydraulic push rod 302 pushes the punch head 303 to descend smoothly, which can quickly and accurately punch the parts. After punching, the motor 403 is reversed. Under the reverse transmission of the toothed belt 405, the limiting plate 402 will quickly move away from the rotation area of ​​the carrier plate 203. The motor 207 is started again. Subsequently, the carrier plate 203 will drive the parts to be punched to continuously deflect to below the punch head 303. The above punching process is repeated, which can continuously punch the parts and further improve the punching efficiency.
