Description

Technical Field

[0001] This utility model relates to the field of vibratory feeder base technology, and in particular to a precision vibratory feeder base with stable connection. Background Technology

[0002] The vibratory feeder base, sometimes called the vibratory feeder chassis, is the core part of the vibratory feeder. By installing a vibrating device on the chassis that generates a certain vibration frequency, the vibrating device drives the chassis to transmit the vibration to the hopper of the vibratory feeder. The parts in the hopper are vibrated and rise along the track of the hopper, thereby realizing automated feeding.

[0003] Existing vibratory feeder bases consist of a top cover and a base, with multiple spring plates between the top cover and the base. These spring plates are tightly secured between the top cover and the base with screws. However, under prolonged high-frequency vibration, the cyclic load on the screws increases significantly, causing them to gradually loosen. Once the screws loosen, the gap between the spring plates will directly increase, and may even cause the spring plates to detach from the top cover or base. This change inevitably alters the vibration frequency of the vibratory feeder, thus affecting its material conveying efficiency and quality.

[0004] Furthermore, due to the insecure fixing of the spring plates, the vibratory feeder cannot effectively utilize the spring plates to absorb and buffer vibration energy during operation, which leads to increased noise levels during operation. This not only reduces the overall performance of the equipment but also interferes with the working environment. Therefore, the applicant has made beneficial designs and found a solution to the above problems. The technical solution described below arose in this context. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the traditional vibratory feeder base design and provide a product that is secure, reliable, and improves operational stability.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A stable precision vibratory feeder base includes a base and a top cover. The base and top cover are evenly distributed with a plurality of equally spaced threaded holes centered on a dot. A countersunk hole is provided at the entrance of each threaded hole. A fixing sleeve is provided in the countersunk hole. The fixing sleeve is evenly distributed with a plurality of equally spaced inwardly retractable connecting parts centered on a dot. The connecting parts are provided with a plurality of equally spaced anti-retraction parts from top to bottom. A spring plate is provided between two of the anti-retraction parts. The connecting parts are provided with fasteners for tightly fitting the fixing sleeve to the inner wall of the countersunk hole. The fasteners are also threadedly connected to the threaded holes.

[0008] Preferably, the inlet of the stop portion is provided with a first inclined surface.

[0009] Preferably, the fixing sleeve includes a plurality of equally spaced fixing parts that can be opened outwards, with the fixing part having a protrusion on its inner wall and the protrusion having a second inclined surface facing the connecting part.

[0010] Preferably, a second gap is provided between adjacent fixed parts to allow them to expand outward.

[0011] Preferably, a retaining ring is provided between the fixing sleeve and the connecting part, and abuts against the top of the countersunk hole.

[0012] Preferably, a first gap is provided between adjacent connecting portions to allow them to retract inward.

[0013] Preferably, the rod portion of the fastener is provided with an abutment portion for pushing the fixing portion outward.

[0014] Preferably, the head of the fastener abuts against the end face of the uppermost connecting part, and the fastener is configured as a screw.

[0015] Beneficial effects:

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention effectively prevents frequency changes in the vibratory feeder caused by loose screws by limiting the movement distance between the spring plates through multiple anti-retraction parts, ensuring the stability of material conveying efficiency and quality. The use of fasteners threaded into the threaded holes and pushing the fixing sleeve tightly against the inner wall of the countersunk hole significantly enhances the connection stability between the fixing sleeve and the base and top cover. With these dual fixing measures, the connection between the spring plates and the base and top cover is more secure, effectively preventing detachment, thereby improving the overall performance of the equipment, reducing noise generation, and minimizing interference with the working environment. This design overcomes the shortcomings of existing technologies, giving the product the advantages of reliable fastening and high operational stability. Attached Figure Description

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In this embodiment of the utility model, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0027] Reference example Figures 1 to 4A precision vibratory feeder base with stable connection includes a base 1 and a top cover 2. The base 1 and top cover 2 have a plurality of equally spaced threaded holes 3 evenly distributed around a central point. A countersunk hole 31 is provided at the entrance of each threaded hole 3. A fixing sleeve 4 is provided in the countersunk hole 31. The fixing sleeve 4 has a plurality of equally spaced, inwardly retractable connecting portions 41 evenly distributed around a central point. Each connecting portion 41 has a plurality of equally spaced anti-retraction portions 42 from top to bottom. A spring plate 5 is provided between two anti-retraction portions 42. The connecting portion 41 is provided with a fastener 6 for tightly fitting the fixing sleeve 4 against the inner wall of the countersunk hole 31. The fastener 6 is also threaded onto the threaded portion. Hole 3, with multiple anti-retraction parts 42, restricts the movement distance between spring plates 5, effectively preventing frequency changes in the vibratory feeder caused by loose screws, and ensuring the stability of material conveying efficiency and quality; fasteners 6 are threadedly connected to threaded holes 3, and push the fixing sleeve 4 to fit tightly against the inner wall of the countersunk hole 31, significantly enhancing the connection stability between the fixing sleeve 4 and the base 1 and top cover 2; under the double fixing measures, the connection between the spring plates 5 and the base 1 and top cover 2 is more stable, effectively preventing detachment, thereby improving the overall performance of the equipment, reducing noise generation, and reducing interference with the working environment. This design overcomes the defects in the existing technology;

[0028] It is worth mentioning that the entrance of the anti-reverse part 42 is provided with a first inclined surface 421. When the spring plate 5 is installed, pressure is applied downward to the spring plate 5 so that it abuts against the first inclined surface 421. The first inclined surface 421 is affected by the pressure of the spring plate 5, which guides the connecting part 41 to shrink in the axial direction, so that the diameter of the anti-reverse part 42 is smaller than the hole diameter of the spring plate 5, thereby enabling it to pass through. Repeat the above assembly action to install multiple spring plates 5 on the connecting part 41.

[0029] It is worth mentioning that the fixing sleeve 4 includes a number of equally spaced fixing parts 43 that can be opened outwards, with the fixing part 43 having a protrusion 431 on its inner wall. The protrusion 431 has a second inclined surface 432 facing the connecting part 41. The second inclined surface 432 is designed to cooperate with the fastener 6, so that the multiple fixing parts 43 and the countersunk hole 31 form multiple connection points, thereby increasing the friction between the fixing sleeve 4 and the countersunk hole 31, ensuring the stable connection of the spring sheet 5, and preventing loosening.

[0030] It is worth mentioning that a second gap 433 is provided between adjacent fixed parts 43 for them to be extended outward;

[0031] It is worth mentioning that a retaining ring 44 is provided between the fixing sleeve 4 and the connecting part 41, and abuts against the top of the countersunk hole 31. The retaining ring 44 restricts the depth of the fixing sleeve 4 entering the countersunk hole 31.

[0032] It is worth mentioning that a first gap 411 is provided between adjacent connecting parts 41 to allow them to retract inward;

[0033] It is worth mentioning that the rod of the fastener 6 is provided with an abutment 61 for pushing the fixing part 43 outward. The tapered abutment 61 is designed so that during the screwing of the fastener 6, the abutment 61 slides on the second inclined surface 432 and pushes the fixing part 43 toward the inner wall of the countersunk hole 31, thereby increasing the friction between the fixing sleeve 4 and the countersunk hole 31. When the fastener 6 is fully connected to the threaded hole 3, the reaction force generated by the fixing part 43 acts on the fastener 6, causing the multiple protrusions 431 to generate a clamping force in the axial direction, effectively increasing the friction between the protrusions 431 and the fastener 6, and further preventing the fastener 6 from loosening under high-frequency vibration.

[0034] It is worth mentioning that the head of the fastener 6 abuts against the end face of the uppermost connecting part 41, and the fastener 6 is set as a screw.

[0035] The above design scheme enables the product to achieve the advantages of secure fastening and improved operational stability.

[0036] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
