Description

Technical Field

[0001] This utility model relates to an automated processing device for medical device parts, belonging to the field of medical device parts processing technology. Background Technology

[0002] CNC (Computer Numerical Control) is short for Computer Numerical Control machine tool, a type of automated machine tool controlled by a program. Currently, when machining products, CNC (Computer Numerical Control) machines often manually insert materials (such as metal blanks for medical device parts) one by one from a stack of materials into the loading / unloading rack, and then place the rack full of materials into the CNC for processing. This manual insertion method is wasteful of manpower, inefficient, and causes operator fatigue. Utility Model Content

[0003] The purpose of this invention is to provide an automated processing device for medical device parts. This automated processing device can release the material block near the discharge port by pushing the wedge block and provide a large and stable pushing force when the material block is discharged from the discharge port, so as to avoid the material block near the support seat from jamming due to insufficient weight.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automated processing device for medical device parts, comprising: a tool holder connected at one end to a CNC machining tool head, a support base connected to the other end of the tool holder, and a housing mounted on the surface of the support base opposite to the tool holder. A material guide channel is provided inside the housing, and an outlet communicating with the material guide channel is formed on the end face away from the support base. Several material blocks are arranged sequentially within the material guide channel. A top spring is provided at the end of the material guide channel opposite to the outlet, extending along the direction of the material guide channel. The two ends of the top spring respectively press against the support base and the material blocks in the material guide channel. A guide hole communicating with the material guide channel is provided on the outer surface of the housing near the outlet. One end of a clamping block is movably embedded in the guide hole and used to press against the material blocks near the outlet in the material guide channel. A first elastic element in a compressed state and perpendicular to the direction of the material guide channel is connected between the end face of the other end of the clamping block and a bracket provided on its outer side. A through hole is formed on the side surface of the clamping block away from the material guide channel. The through hole is set as an inclined surface opposite to the inner wall of the material guide channel. The inclined surface of a wedge block movably installed in the through hole slides in contact with the inclined surface of the inner wall of the through hole. A second elastic member in a compressed state and extending along the moving direction of the wedge block is connected between the end face of the wedge block embedded in the through hole and the stop block set on its outer side. The end face of the other end of the wedge block extends to the outside of the clamping block. When the wedge block moves towards the stop block and squeezes the second elastic member, the clamping block moves away from the material guide channel and squeezes the first elastic member.

[0005] The following are further improvements to the above technical solution: 1. In the above solution, the bracket further includes: a main body disposed on the side opposite to the guide hole and the material guide channel, and support parts respectively located on both sides of the main body, wherein the two support parts are respectively located on both sides of the guide hole and are installed and connected to the outer surface of the housing.

[0006] 2. In the above scheme, both the clamping block and the main body of the bracket are provided with a first limiting groove for the end of the first elastic member to be embedded.

[0007] 3. In the above scheme, both the wedge block and the stop block installed on the outer surface of the housing are provided with a second limiting groove for the end of the second elastic member to be embedded.

[0008] 4. In the above scheme, a strip-shaped hole is opened on the wedge block in the same direction as its movement, and a limiting pin fixedly installed on the clamping block is embedded in the strip-shaped hole and slides in cooperation with the inner wall of the strip-shaped hole.

[0009] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model discloses an automated processing device for medical device parts. A material guide channel is provided inside a housing mounted on the surface of a support base opposite to the tool handle. Several material blocks are arranged sequentially within the material guide channel. A top spring, positioned opposite the outlet end of the through-channel, is installed along the extending direction of the material guide channel. The two ends of the top spring respectively press against the support base and the material blocks within the material guide channel. A guide hole communicating with the material guide channel is provided on the outer surface of the housing near the outlet end. One end of a clamping block is movably embedded in the guide hole and used to press against the material blocks near the outlet in the material guide channel. A first elastic element, in a compressed state and perpendicular to the extending direction of the material guide channel, is connected between the end face of the other end of the clamping block and a support set on its outer side. A [missing information - likely a design element or feature] is provided on the side surface of the clamping block away from the material guide channel. The through hole has an inclined surface opposite to the inner wall of the guide channel. An inclined surface on a wedge block that can be movably installed in the through hole slides in contact with the inclined surface of the inner wall of the through hole. A second elastic element in a compressed state and extending along the moving direction of the wedge block is connected between the end face of the wedge block embedded in the through hole and a stop block set on its outer side. The end face of the other end of the wedge block extends to the outside of the clamping block. While the material block rotates with the cutter head for processing, multiple material blocks can be stably and sequentially stored in the guide channel without being affected by the rotation of the cutter head. The wedge block can also be pushed to release the material block near the discharge port and provide a large and stable thrust when the material block is discharged from the discharge port. This avoids the material block near the support seat from jamming due to insufficient weight, thereby achieving stable feeding of material blocks, reducing manual labor, and improving processing efficiency.

Detailed Implementation

[0012] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0013] Example 1: An automated processing device for medical device parts includes: a tool holder 15 connected at one end to a CNC machining tool head, a support base 14 connected to the other end of the tool holder 15, and a housing 2 mounted on the surface of the support base 14 opposite to the tool holder 15. A material guide channel 1 is provided inside the housing 2. An outlet 3 communicating with the material guide channel 1 is formed on the end face of the housing 2 away from the support base 14. Several material blocks 100 are arranged sequentially within the material guide channel 1. An extension along the material guide channel 1 is provided at the end opposite to the outlet 3 within the material guide channel 1, which is open at both ends. A top spring 13 is oriented in a certain direction. The two ends of the top spring 13 are in pressure contact with the support base 14 and the material block 100 in the guide channel 1, respectively. A guide hole 4 communicating with the guide channel 1 is opened on the outer surface of the housing 2 near the discharge port 3. One end of a clamping block 5 is movably embedded in the guide hole 4 and is used to press and contact the material block 100 in the guide channel 1 near the discharge port 3. A first elastic member 7 in a compressed state and perpendicular to the extension direction of the guide channel 1 is connected between the end face of the other end of the clamping block 5 and the bracket 6 provided on its outer side. A through hole 8 is formed on the side surface of the clamping block 5 away from the material guide channel 1. The through hole 8 is set as an inclined surface opposite to the inner wall of the material guide channel 1. An inclined surface of a wedge block 9 movably installed in the through hole 8 slides in contact with the inclined surface of the inner wall of the through hole 8. A second elastic member 11 in a compressed state and extending along the moving direction of the wedge block 9 is connected between the end face of the wedge block 9 embedded in the through hole 8 and the stop block 10 set on its outer side. The end face of the other end of the wedge block 9 extends to the outside of the clamping block 5. When the wedge block 9 moves towards the stop block 10 and squeezes the second elastic member 11, the clamping block 5 moves away from the material guide channel 1 and squeezes the first elastic member 7.

[0014] The aforementioned bracket 6 further includes: a main body 61 disposed on the side of the guide hole 4 opposite to the material guide channel 1, and support parts 62 respectively located on both sides of the main body 61. The two support parts 62 are respectively located on both sides of the guide hole 4 and are installed and connected to the outer surface of the housing 2. The main body 61 of the clamping block 5 and the bracket 6 are each provided with a first limiting groove 71 for the end of the first elastic member 7 to be inserted; Both the wedge block 9 and the stop block 10 installed on the outer surface of the housing 2 have a second limiting groove 111 for the end of the second elastic member 11 to be inserted.

[0015] Example 2: An automated processing device for medical device parts, comprising: a tool holder 15 connected at one end to a CNC machining tool head, a support base 14 connected to the other end of the tool holder 15, and a housing 2 mounted on the surface of the support base 14 opposite to the tool holder 15. A material guide channel 1 is provided inside the housing 2, and an outlet 3 communicating with the material guide channel 1 is formed on the end face of the housing 2 away from the support base 14. A plurality of material blocks 100 are arranged sequentially within the material guide channel 1. An extension along the material guide channel 1 is provided at the end of the material guide channel 1 opposite to the outlet 3. A top spring 13 is oriented in a certain direction. The two ends of the top spring 13 are in pressure contact with the support base 14 and the material block 100 in the guide channel 1, respectively. A guide hole 4 communicating with the guide channel 1 is opened on the outer surface of the housing 2 near the discharge port 3. One end of a clamping block 5 is movably embedded in the guide hole 4 and is used to press and contact the material block 100 in the guide channel 1 near the discharge port 3. A first elastic member 7 in a compressed state and perpendicular to the extension direction of the guide channel 1 is connected between the end face of the other end of the clamping block 5 and the bracket 6 provided on its outer side. A through hole 8 is formed on the side surface of the clamping block 5 away from the material guide channel 1. The through hole 8 is set as an inclined surface opposite to the inner wall of the material guide channel 1. An inclined surface of a wedge block 9 movably installed in the through hole 8 slides in contact with the inclined surface of the inner wall of the through hole 8. A second elastic member 11 in a compressed state and extending along the moving direction of the wedge block 9 is connected between the end face of the wedge block 9 embedded in the through hole 8 and the stop block 10 set on its outer side. The end face of the other end of the wedge block 9 extends to the outside of the clamping block 5. When the wedge block 9 moves towards the stop block 10 and squeezes the second elastic member 11, the clamping block 5 moves away from the material guide channel 1 and squeezes the first elastic member 7.

[0016] The moving direction of the aforementioned wedge block 9 is the same as the extending direction of the material guide channel 1, and the end face of the aforementioned wedge block 9 opposite to the end of the stop block 10 is located outside the end face of the end of the housing 2 where the discharge port 3 is opened. The inclined surfaces of the inner wall of the through hole 8 on the clamping block 5 and the inclined surfaces on the wedge block 9 are both gradually inclined towards the material guide channel 1 in the direction close to the stop block 10. The wedge block 9 has a strip hole 121 that is aligned with its moving direction. A limiting pin 122 fixedly mounted on the clamping block 5 is embedded in the strip hole 121 and slides in cooperation with the inner wall of the strip hole 121.

[0017] Working principle: When in use, it is generally used in conjunction with a jig for processing material blocks; Under normal conditions, when the wedge block is not pushed, the wedge block is located in the initial position away from the stop block under the action of the second elastic element, while the clamping block is located in the initial position close to the guide channel under the action of the first elastic element and presses the material block closest to the discharge port in the guide channel. When feeding is required, the discharge port on the housing is moved to the top of the clamping fixture by rotating the CNC machining head, and then the housing is driven to move towards the machining clamping fixture of the material block. During the process of the housing moving towards the clamping fixture, the lower end face of the wedge block first contacts the clamping fixture and is squeezed to move closer to the stop block, squeezing the second elastic element. At the same time, the clamping block is pushed by the inclined surface of the wedge block and can only move away from the guide channel under the limitation of the guide housing, squeezing the first elastic element, thereby releasing the pressure on the block closest to the discharge port. At this time, the block closest to the discharge port moves outward from the discharge port to the processing clamping fixture under the gravity of itself and other blocks above it, realizing the automatic discharge of the block. The top spring can provide a larger and more stable pushing force when the block is discharged from the discharge port, avoiding the block near the support seat from jamming due to insufficient weight. After one loading is completed, the shell moves away from the clamping fixture. The wedge block, which is no longer squeezed by the clamping fixture, returns to its initial position under the action of the second elastic element. The clamping block, which is no longer squeezed by the wedge block, returns to its initial position under the action of the first elastic element.

[0018] When using the aforementioned automated processing device for medical device parts, while the material blocks rotate with the cutter head for processing, it can simultaneously and stably store multiple material blocks sequentially in the guide channel without being affected by the rotation of the cutter head. It can also release material blocks near the discharge port through the push wedge block, and provide a large and stable thrust when the material blocks are discharged from the discharge port, avoiding the situation where material blocks near the support seat get stuck due to insufficient weight. This achieves stable feeding of material blocks, reduces manual labor, and improves processing efficiency.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
