Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Specific examples are given below.

[0027] See also Figure 1 - Figure 6The utility model provides a CNC lathe for processing metal parts, including a lathe body 1, an inspection door 101 and a locking mechanism; the inspection door 101 is hingedly connected to one side of the lathe body 1, a lock hole 102 is opened on one side of the lathe body 1, a protection box 3 is fixedly connected to the inner wall of the lathe body 1, the locking mechanism is arranged inside the protection box 3, and the locking mechanism is arranged inside the lathe body 1; the locking mechanism includes a lock column 201, a lock head 202, a baffle 203, a spring 204, a lock block 205 and a movable rod 206, the One end of the lock column 201 is fixedly connected to one side of the inspection door 101, and the other end of the lock column 201 passes through the lock hole 102 and extends to the inside of the lathe body 1. The lock head 202 is fixedly connected to one end of the lock column 201, and the baffle 203 is fixedly connected to the inner wall of the lathe body 1. One end of the spring 204 is fixedly connected to the inner side of the baffle 203. The lock block 205 is fixedly connected to the other end of the spring 204 and is located on the outside of the lock head 202. One end of the movable rod 206 is fixedly connected to the outside of the lock block 205. The other end of 6 penetrates to the outside of the baffle plate 203, and the movable rod 206 is movably arranged inside the spring 204. When working, when the staff completes the maintenance of the lathe body 1, they can directly push the maintenance door 101 to close it. During the closing process of the maintenance door 101, the lock column 201 and the lock head 202 will penetrate the lock block 205 and extend to the inside of the lathe body 1. At the same time, the lock head 202 will squeeze the lock block 205 outward at the same time. After the lock block 205 is squeezed, it will squeeze the spring 204 and the movable rod 206 outward at the same time. When the maintenance door 101 is completely closed, After closing, the lock head 202 will move to the inner side of the lock block 205, and the lock block 205 will be pushed to the outer side of the lock head 202 under the elasticity of the spring 204, so that the inspection door 101 can be automatically locked through the lock column 201 to prevent the lathe body 1 from vibrating during the processing and causing the inspection door 101 to open automatically. For this reason, it can provide better protection for the lathe body 1 and reduce the situation where external debris enters the interior of the equipment through the inspection door 101, thereby reducing the possibility of equipment failure and improving the stability of the equipment during operation.

[0028] Further, such as Figure 1 - Figure 6As shown, an unlocking mechanism is provided inside the protection box 3, and the unlocking mechanism includes a round shaft 401, a gear 402, a toothed rod 403, a connecting rod 404 and a bent rod 405. The round shaft 401 is fixedly connected to the inside of the protection box 3, the gear 402 is sleeved on the surface of the round shaft 401, the toothed rod 403 is meshingly connected to the front and rear sides of the gear 402, one end of the connecting rod 404 is fixedly connected to the toothed rod 403, and the other end of the connecting rod 404 is fixedly connected to the locking block 205, one end of the bent rod 405 is fixedly connected to one end of the bottom movable rod 206, and the other end of the bent rod 405 passes through the protection box 3 and extends to one side of the lathe body 1. During operation, when the inspection door 101 needs to be opened, the bent rod 405 can be pushed downward by the pushing block 6 first. The downward push of the bent rod 405 will drive the bottom movable rod 206 to move downward. When the gear 403 on the front side moves downward, it will drive the gear 402 to rotate on the surface of the circular shaft 401. The gear 402 rotates and drives the gear 403 on the rear side to move upward. When the gear 403 on the rear side moves upward, it can simultaneously drive the top lock block 205 and the connecting rod 404 to move upward. When the lock block 205 moves outward, the lock block 205 can be separated from the limit of the lock head 202, and then the lock column 201 and the lock head 202 can be opened and separated from the inside of the lock hole 102 to unlock. In this way, the inspection door 101 can be unlocked and opened quickly and conveniently, so that it is convenient for the staff to inspect the inside of the lathe body 1 and the practicability of the lathe body 1 can be improved.

[0029] Further, such as Figure 1 - Figure 6 As shown, the interior of the protective box 3 is fixedly connected with an auxiliary rod 501, and the front and rear sides of the locking block 205 are fixedly connected with auxiliary blocks 502, and the auxiliary blocks 502 are slidably connected to the surface of the auxiliary rod 501. During operation, when the locking block 205 moves, it can drive the auxiliary block 502 to slide on the surface of the auxiliary rod 501. In order to prevent the locking block 205 from being displaced during movement due to lack of limit, the auxiliary block 502 and the auxiliary rod 501 are matched and connected, which can play an auxiliary limiting role for the locking block 205, thereby preventing the locking block 205 from moving and affecting the normal operation of the locking mechanism and the unlocking mechanism.

[0030] Further, such as Figure 1 - Figure 6As shown, a vertical groove 8 is opened on one side of the lathe body 1, and the diameter of the vertical groove 8 is used in conjunction with the bending rod 405. During operation, when the bending rod 405 is pushed to move downward, the bending rod 405 can be flexibly moved inside the vertical groove 8, and at the same time, it is convenient for the bending rod 405 to pass through the outside of the lathe body 1, so as to facilitate the staff to push the bending rod 405 to move, and prevent the bending rod 405 from colliding with the lathe body 1 when moving, causing operation interference.

[0031] Further, such as Figure 1 - Figure 6 As shown, one end of the curved rod 405 is fixedly connected to a pushing block 6, and the pushing block 6 is in an arc shape. When working, the curved rod 405 can be pushed downward by the pushing block 6 to unlock the door. As a result, the contact area between the palm of the staff and the pushing block 6 can be increased under the action of the pushing block 6, thereby preventing the palm from slipping off the surface of the pushing block 6 when pushing the curved rod 405, thereby making it more convenient to operate the unlocking mechanism.

[0032] Further, such as Figure 1 - Figure 6 As shown, an auxiliary ring 7 is fixedly connected to the surface of the circular shaft 401, and the auxiliary rings 7 are respectively located on both sides of the gear 402. When working, the gear 402 will rotate on the surface of the circular shaft 401. In order to prevent the gear 402 from being displaced when rotating on the surface of the circular shaft 401, the gear 402 can be auxiliary limited by the auxiliary ring 7 to prevent the gear 402 from being displaced during rotation, causing the toothed rod 403 to be disconnected from the gear 402, and at the same time affecting the normal operation of the unlocking mechanism.

[0033] Further, such as Figure 1 - Figure 6 As shown, one side of the locking block 205 is set as an inclined surface, and the shape of the locking head 202 is an arc shape. The locking head 202 is used in conjunction with the locking block 205. When working, the inclined surface of the locking block 205 can be matched and connected with the arc-shaped locking head 202, thereby reducing the resistance generated by the locking head 202 pushing the locking block 205, and allowing the locking head 202 to push the locking block 205 more smoothly and cooperate with it to limit the position.

[0034] Working principle: When the staff has completed the maintenance of the lathe body 1, they can directly push the maintenance door 101 to close it. During the closing process of the maintenance door 101, the lock column 201 and the lock head 202 will penetrate the lock block 205 and extend to the inside of the lathe body 1. At the same time, the lock head 202 will squeeze the lock block 205 outward at the same time. After the lock block 205 is squeezed, it will also squeeze the spring 204 and the movable rod 206 outward. When the maintenance door 101 is completely closed, the lock head 202 will move to the inside of the lock block 205, and the lock block 205 will be pushed to the outside of the lock head 202 under the elasticity of the spring 204. The maintenance door 101 can be automatically locked through the connecting column to prevent the lathe body 1 from vibrating during the processing process. 1 automatically opens, so it can provide a better protection effect for the lathe body 1, and at the same time reduce the situation that external debris enters the interior of the equipment through the inspection door 101, so as to reduce the situation that the equipment fails and improve the stability of the equipment during operation. When the inspection door 101 needs to be opened, the bent rod 405 can be pushed downward by the pushing block 6. The downward push of the bent rod 405 will drive the bottom movable rod 206 to move downward. The downward movement of the movable rod 206 will also drive the bottom locking block 205 to move downward and squeeze the spring 204. When the bottom locking block 205 moves downward, it will drive the front gear rod 403 to move downward through the connecting rod 404. The front gear rod 403 moves downward and drives the gear 402 on the surface of the round shaft 401 When the gear 402 rotates, the gear 403 at the rear side will move upward. When the gear 403 at the rear side moves upward, it can simultaneously drive the top locking block 205 and the connecting rod 404 to move upward. When the locking block 205 moves outward, the locking block 205 can be separated from the limit of the lock head 202. Then, the lock column 201 and the lock head 202 can be opened and separated from the inside of the lock hole 102 to unlock the door. In this way, the inspection door 101 can be unlocked and opened quickly and conveniently, so that it is convenient for the staff to inspect the inside of the lathe body 1 and the practicality of the lathe body 1 can be improved. When the locking block 205 is moving, it can drive the auxiliary block 502 to slide on the surface of the auxiliary rod 501, thereby playing an auxiliary limiting role for the locking block 205. In order to prevent the lock block 205 from being displaced when moving due to lack of limit, which will affect the normal operation of the locking mechanism and the unlocking mechanism and affect the lathe body 1 at the same time, the lock can be unlocked by pushing the bending rod 405 downward by the pushing block 6. As a result, the contact area between the palm of the staff and the pushing block 6 can be increased under the action of the pushing block 6, and the palm can be prevented from slipping off the surface of the pushing block 6 when pushing the bending rod 405, so that the unlocking mechanism can be operated more conveniently. The gear 402 will rotate on the surface of the circular shaft 401. In order to prevent the gear 402 from being displaced when the surface of the circular shaft 401 rotates, the gear 402 can be auxiliary limited by the auxiliary ring 7 to prevent the gear 402 from being displaced when rotating and causing the gear rod 403 to be disconnected from the gear 402.At the same time, it will affect the normal operation of the unlocking mechanism, and the inclined surface of the lock block 205 can be matched with the arc-shaped lock head 202, so as to reduce the resistance generated by the lock head 202 pushing the lock block 205, and make the lock head 202 push the lock block 205 more smoothly and cooperate with it to limit the position.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
