Description

Technical Field

[0001] This invention relates to the field of stethoscope manufacturing technology, and more particularly to a processing and feeding device for stethoscope head production. Background Technology

[0002] The stethoscope is the most commonly used diagnostic tool by doctors. Its structure includes the stethoscope head, sound tube, and ear hook. The stethoscope head comes in two types: diaphragm and cup. The diaphragm head is good at hearing high-frequency sounds, while the cup head is suitable for hearing low-frequency sounds or noises. The stethoscope head of existing stethoscopes, especially advanced stethoscopes, is usually made of metal. The manufacturing of the stethoscope head is mainly divided into two stages: blank forming and precision machining. The stethoscope tube interface hole is located on the side or back of the stethoscope head and is used to insert the Y-shaped rubber tube. Therefore, it is necessary to drill a hole in the stethoscope head blank.

[0003] Chinese Patent Publication No.: CN 214443238 U, Publication Date: October 22, 2021. This application provides an automatic stethoscope drilling device, belonging to stethoscope production equipment, including a base and a drilling assembly. The drilling assembly includes a mounting base, on which a drill bit for drilling is mounted. A slide rail is provided below the mounting base, and a slider is mounted on the slide rail. The mounting base and the slider are fixedly connected. A top rod can press the stethoscope onto the base for fixation. The movement of the mounting base on the slide rail enables the drill bit to feed, thereby automatically drilling holes in the side of the stethoscope. A top rod is mounted above the base. The shortcomings of this technical solution are: 1. The lack of material fixation during drilling leads to reduced drilling accuracy; 2. It is difficult to achieve batch material replenishment during feeding; 3. The material blown out during unloading is messy and disorderly, difficult to organize, and easily deformed during collection.

[0004] In summary, the existing stethoscope production process suffers from poor stability, reduced operational accuracy, low material loading and unloading efficiency, and difficulty in quickly adapting to mass production operations. Summary of the Invention

[0005] In order to overcome the shortcomings of existing technologies in stethoscope production, such as poor stability of drilling operations, reduced operation accuracy, low loading and unloading efficiency, and difficulty in quickly tidying up for mass production, a processing and unloading device for stethoscope head production is provided, which improves drilling operation stability, drilling accuracy, loading and unloading efficiency, and facilitates tidying up.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A processing and unloading device for stethoscope head production, including A rotary table is provided with a support, and the support is connected to a rotating mechanism and a drill bit. The rotary table is connected to the rotating mechanism and has a working trough and a feeding trough. The working trough is connected to a base. The feeding guide rail is connected to the support and is equipped with a feeding guide groove, which is matched with the position of the working groove. The limiting bracket is connected to the feeding guide rail and is equipped with a material blocking groove, the position of which is adapted to the feeding guide groove. The fixed clamp rod has a push structure connected to the support, and the fixed clamp rod is movablely connected to the working groove through the push structure. The material feeder is detachably connected to the material feed trough and has a material collection cylinder. The material feeder is movably connected to the support and the positions of the material feeder and the material feed trough are adapted to each other.

[0007] A rotating mechanism, mounted on a support, drives a connected rotating disk, allowing the disk to rotate on the support. This, in turn, allows the working trough and the feeding trough on the rotating disk to move. When the working trough moves to below the drill bit for drilling, the diameter of the working trough is larger than the diameter of the stethoscope head to facilitate rapid material loading. A base supports the material placed on it, providing support during drilling. A feeding guide rail, via a feed chute, guides materials in batches, enabling continuous feeding, drilling, and unloading, thus improving production efficiency. A limiting bracket's stop groove restricts the material being fed, and, in conjunction with the larger working trough opening, ensures... The material enters the working trough, improving the error tolerance and smoothness of the feeding process. Fixed clamping rods are connected within the working trough and can move within it via a pushing structure. Several fixed clamping rods are arranged and move towards the center of the working trough to gradually clamp the material, ensuring it is fully clamped and fixed before drilling, thus maintaining high precision and stability during drilling. The unloading clamp, connected by a support, can movably remove the drilled material and place it into the collection cylinder of the unloading trough for automatic collection and stacking, enabling continuous batch feeding. The detachable collection cylinder allows for quick removal of entire batches of material for efficient feeding. This achieves continuous operation, automatic loading and unloading, easy batch processing, stable and high-precision drilling, and improved efficiency in stethoscope head production.

[0008] Preferably, the support is connected to a support rod, and the feeding guide rail is connected to the support rod. The feeding guide rail is connected to a limit roller, and the limit roller is fitted with an anti-slip rubber sleeve, which is placed at one end of the feed chute. One end of the support rod is fixed to the support, and the other end is connected to and supports the feeding guide rail. The limit roller is connected to the feeding guide rail and fixedly fitted with the anti-slip rubber sleeve to limit the material stacked in the feed chute. Simultaneously, the anti-slip rubber sleeve increases the friction with the metal surface of the material, preventing the material from sliding or shifting. This further improves the stability of the feeding process.

[0009] Preferably, the feeding guide rail is equipped with rotating holes, and the limiting rollers are inserted into these holes. The limiting rollers are connected to limiting plates, and the feeding guide rail is connected to a second rotating mechanism, which is also connected to the limiting rollers. The rotating holes are openings arranged opposite each other on the feeding guide rail. Both ends of the limiting rollers are inserted into the rotating holes, and limiting plates are connected to the ends to ensure stable installation of the limiting rollers. The second rotating mechanism is installed on the feeding guide rail to provide rotational power for the limiting rollers, thereby allowing the anti-slip rubber sleeve to push out the foremost material from the opening of the discharge guide chute. This further improves the automation level and feeding efficiency of the operation.

[0010] Preferably, the feeding guide rail is equipped with a telescopic mechanism, and a rear side plate is connected to the other end of the feeding guide groove. The rear side plate is connected to an elastic mechanism, which abuts against the telescopic mechanism. The telescopic mechanism is connected to a feeding rod, which is arranged opposite to the limiting roller. The telescopic mechanism is installed on the feeding guide rail to support the stacked material at the tail end via the feeding rod. It also drives the material forward. The elastic mechanism buffers the telescopic mechanism, allowing it to move within the feeding guide groove according to the remaining material volume to supplement automatic feeding. This improves feeding efficiency and automation.

[0011] Preferably, the feed guide chute has mounting holes at its opening, and a mounting screw is connected to the limiting bracket. The mounting screw is inserted into the mounting hole, and a fixing nut is threaded onto the mounting screw. The feeding guide chute's opening, through the engagement of the mounting hole and the mounting screw hole, connects the limiting bracket to the feeding guide rail, and is secured by the fixing nut. This facilitates assembly and allows for height adjustment of the limiting bracket, ensuring its height matches the rotating disc and preventing interference with its rotation. This improves the assembly efficiency and operational smoothness of the device components.

[0012] Preferably, the pushing structure includes a clamping block and a clamping bracket. The rotating disk has a movable slot, and the working groove has a movable hole. One end of the movable hole communicates with the movable slot, and the other end of the movable hole communicates with the working groove. The clamping block is inserted into the movable hole, and the clamping bracket is inserted into the movable slot. A second telescopic mechanism is connected to the support, and the clamping bracket is connected to the second telescopic mechanism. The clamping bracket is slidably connected to the clamping block. The clamping block is connected to the movable hole and is arranged opposite to one side of the fixed clamping rod. The other side of the fixed clamping rod is arranged opposite to the base. The clamping bracket then enters the movable slot, pushing the clamping block to clamp the material on the base and keep it fixed. The second telescopic mechanism provides the moving power for the clamping bracket, thereby achieving rapid fixing of the fixed clamping rod and maintaining the stability of the drilling. This improves the material fixing efficiency and stability.

[0013] Preferably, the working trough is connected to several movable guide rods, and the fixed clamping rod has through holes. The movable guide rods are inserted into the through holes, and a second elastic mechanism is sleeved on the movable guide rod. One end of the second elastic mechanism is connected to the fixed clamping rod, and the other end abuts against the base. The movable guide rods are connected to the wall of the working trough and inserted into the fixed clamping rods through the through holes, thereby guiding the movement of the fixed clamping rods along the movable guide rods. The second elastic mechanism allows the fixed clamping rods to automatically reset after losing the thrust of the clamping bracket, thus automatically releasing the material for easy unloading and facilitating the next fixing operation. This improves the continuous operation efficiency of the device.

[0014] Preferably, the support is connected to a lifting block and a lowering block. The rotating disk has a movable insertion hole to which an adjusting rod is inserted. The adjusting rod is connected to the base and to a docking block one and a docking block two. The lifting block has a lifting ramp, and the lowering block has a resetting ramp. The docking block one is slidably connected to the lifting ramp, and the docking block two is slidably connected to the resetting ramp. By connecting the lifting block, the support moves the base to the front of the docking block one during the rotation of the rotating disk. The adjusting rod moves along the lifting ramp of the lifting block through the docking block one, thus raising the base and material from the working trough for later material removal. During the rotation of the rotating disk, the base moves to the front of the docking block two, and the adjusting rod moves along the resetting ramp of the lowering block through the docking block two, thus resetting the base and material from the working trough. This allows the base to automatically reset after material removal for later material feeding and drilling. This achieves the effect of improving the automation level and feeding / discharging efficiency of the device.

[0015] Preferably, the feeding clamp includes a fixed frame and a finger cylinder. The fixed frame is connected to a support and a telescopic mechanism three is connected to the fixed frame. The finger cylinder is connected to the telescopic mechanism three. The fixed frame is mounted on the support to support the telescopic mechanism three, allowing the finger cylinder to move back and forth, so that the finger cylinder can pick up the material for easy feeding. This achieves the effect of improving the automation level and efficiency of feeding.

[0016] Preferably, the feeding trough is connected to a mounting base, which has a mounting port with internal threads. The end of the collecting cylinder has external threads that match the internal threads. The collecting cylinder is threadedly connected to the mounting base, and the side of the collecting cylinder has an air outlet. The feeding trough opening is connected to the mounting base, and the mounting port of the mounting base has a threaded structure matching the collecting cylinder, allowing the collecting cylinder to be screwed into the mounting base by rotation. This facilitates the installation of the collecting cylinder for collecting materials and its removal for discharge. The side of the collecting cylinder has an opening for air outlet to observe the remaining material and ensure smooth material feeding with balanced internal and external air pressure. This improves the smoothness and convenience of material feeding.

[0017] The beneficial effects of this invention are: enabling continuous operation of the device; automatic loading and unloading and easy batch processing; stable and high precision during drilling; improving the production efficiency of stethoscope heads; improving loading stability; improving the assembly efficiency and operational smoothness of device components; improving material fixing efficiency and stability; improving the automation level and feeding / unloading efficiency of the device; and improving the smoothness and convenience of unloading.
