Description

Technical Field

[0001] This utility model relates to the field of eccentric wheels, and in particular to a metal eccentric wheel positioning and fixing structure that is easy to disassemble and assemble. Background Technology

[0002] To meet the precise fixing requirements of metal eccentric wheels in processing and assembly scenarios, the metal eccentric wheel positioning and fixing structure is a mechanical structure specifically designed to limit the position and securely clamp metal eccentric wheels. Its core function is to ensure that the eccentric wheel does not shift, shake, or deviate during subsequent operations through the cooperation of specific mechanical components, thereby ensuring processing accuracy, assembly quality, and operational safety. It is widely used in machinery manufacturing, automotive parts production, hardware processing, and other fields, and can be designed in different types such as manual adjustment, semi-automatic drive, or fully automatic control, depending on the size, shape, and application requirements of the eccentric wheel.

[0003] In the prior art, the usage process and operation steps of the metal eccentric wheel positioning and fixing structure are usually as follows: First, the operator needs to manually adjust the clamping components in the positioning structure according to the actual size of the eccentric wheel to be fixed, such as by rotating the adjusting screw to push the clamping block to move so that the distance between the clamping blocks is adapted to the outer diameter of the eccentric wheel.

[0004] In practical applications, manually adjusting the clamping distance is highly dependent on the operator's experience. Different operators may tighten the clamping force differently, which can easily lead to uneven clamping force. Insufficient force can cause the eccentric wheel to shift slightly during operation, while excessive force can damage the outer wall of the eccentric wheel or deform the clamping components. Moreover, the adjustment process is time-consuming and cannot meet the high-efficiency positioning requirements of mass production. Therefore, based on the above problems, a metal eccentric wheel positioning and fixing structure that is easy to disassemble and assemble has been introduced. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a metal eccentric wheel positioning and fixing structure that is easy to disassemble and assemble. It aims to solve the problem in the prior art that different operators have different tightening forces, which can easily lead to uneven clamping force and slight displacement of the eccentric wheel during operation due to insufficient force.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a metal eccentric wheel positioning and fixing structure that is easy to disassemble and assemble, including a connecting plate, a base fixedly connected to the outer wall of the connecting plate, and a positioning mechanism provided on the outer wall of the connecting plate;

[0007] The positioning mechanism includes a fixed seat, the inner wall of which is slidably connected to the outer wall of the connecting plate, a limit block fixedly connected to the inner wall of the fixed seat, a lower partition plate fixedly connected to the bottom of the fixed seat, a gear rotatably connected to the bottom of the outer wall of the connecting plate via a rotating shaft, and an outer toothed plate slidably connected to the inner wall of the lower partition plate, the gear meshing with the outer wall of the outer toothed plate.

[0008] As a further description of the above technical solution: a pulley is fixedly connected to the extension end of the inner wall shaft of the gear, a motor is fixedly connected to the outer wall of the base, a pulley is fixedly connected to the output end of the motor, and a transmission belt is driven to the outer wall of the pulley.

[0009] As a further description of the above technical solution: the inner wall of the outer toothed plate is slidably connected to an inner toothed plate, and the top of the outer toothed plate is threadedly connected to a fixing bolt, the extension end of which abuts against the outer wall of the inner toothed plate.

[0010] As a further description of the above technical solution: the inner wall of the fixed base is slidably connected to an inner sliding plate, and the inner wall of the inner sliding plate is fixedly connected to a fixed suction cup.

[0011] As a further description of the above technical solution: the limiting block is wedge-shaped, and the inner wall of the fixing seat is provided with an eccentric wheel.

[0012] As a further description of the above technical solution: there are two sets of inner sliding plates and fixed suction cups, and the inner sliding plates and fixed suction cups are symmetrically arranged at equal intervals on the inner walls of the two sets of fixed seats.

[0013] As a further description of the above technical solution: there are two sets of external gear plates, and the two sets of external gear plates are symmetrically installed at the bottom of the fixed seat and both mesh with the outer wall of the gear.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, power is transmitted through the cooperation of the pulley and the transmission belt, which drives the gear to rotate. The gear meshes with two sets of external gear plates, driving the external gear plates to slide along the lower partition, thereby driving the fixed seat to move along the connecting plate.

[0016] 2. In this utility model, by sliding the outer tooth plate and the inner tooth plate together, combined with the fixing effect of the fixing bolts, the tooth spacing can be adjusted according to the thickness of the eccentric wheel, thereby improving the adaptability to eccentric wheels of different sizes.

[0017] 3. In this utility model, the two sets of inner sliding plates and the fixed suction cup on the inner wall of the fixed base cooperate with each other to perform preliminary adsorption and limit on the eccentric wheel before positioning to prevent displacement, while the fixed connection between the base and the connecting plate provides stable support for the entire structure.

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

[0025] Reference Figures 1-3This utility model provides an embodiment of a metal eccentric wheel positioning and fixing structure that is easy to assemble and disassemble. The structure includes a connecting plate 1, which connects the various components of the fixing device and provides sliding support for a fixing seat 311. A base 2 is fixedly connected to the outer wall of the connecting plate 1, supporting the entire positioning and fixing structure and fixing the motor 318. A positioning mechanism 3 is provided on the outer wall of the connecting plate 1, achieving precise positioning and stable fixing of the metal eccentric wheel. The positioning mechanism 3 includes a fixing seat 311, which accommodates the eccentric wheel to be fixed and connects it along the connecting plate. The connecting plate 1 slides to achieve clamping. The inner wall of the fixing seat 311 is slidably connected to the outer wall of the connecting plate 1. A limit block 312 is fixedly connected to the inner wall of the fixing seat 311. The limit block 312 is used to enhance the squeezing and limiting effect on the eccentric wheel when the fixing seat 311 clamps. A lower partition 313 is fixedly connected to the bottom of the fixing seat 311. The lower partition 313 is used to limit the sliding trajectory of the outer toothed plate 315 to prevent deviation. A gear 314 is rotatably connected to the bottom of the outer wall of the connecting plate 1 through a rotating shaft. The gear 314 is used to drive the outer toothed plate 315 to move by rotating itself. The inner wall of the lower partition 313 slides... An external gear plate 315 is attached, which drives the fixed base 311 to move synchronously and cooperates with the internal gear plate 319 to adjust the tooth spacing. A gear 314 meshes with the outer wall of the external gear plate 315. A pulley 316 is fixedly connected to the extended end of the shaft on the inner wall of the gear 314. The pulley 316 receives power transmitted from the motor 318 and drives the gear 314 to rotate. A motor 318 is fixedly connected to the outer wall of the base 2. The motor 318 provides power output for the transmission and clamping actions of the positioning mechanism 3. The output end of the motor 318 is fixedly connected to the pulley 316. The outer wall is connected to a transmission belt 317, which is used to connect the pulley 316 at the output end of the motor 318 and the pulley 316 on the shaft of the gear 314 to achieve power transmission. The inner wall of the outer gear plate 315 is slidably connected to an inner gear plate 319, which is used to cooperate with the outer gear plate 315 to adjust the tooth pitch to adapt to eccentric wheels of different thicknesses. The top of the outer gear plate 315 is threaded with a fixing bolt 4, which is used to fix the relative position of the inner gear plate 319 and the outer gear plate 315 to prevent slippage. The extended end of the fixing bolt 4 abuts against the outer wall of the inner gear plate 319.

[0026] Reference Figures 2-4The inner wall of the fixed base 311 is slidably connected to an inner slide plate 5. The inner slide plate 5 is used to install the fixed suction cup 6 and can slide adaptably with the shape of the eccentric wheel. The inner wall of the inner slide plate 5 is fixedly connected to the fixed suction cup 6. The fixed suction cup 6 is used to initially adsorb and limit the eccentric wheel to prevent displacement during positioning. The limiting block 312 is wedge-shaped. The inner wall of the fixed base 311 is provided with an eccentric wheel. There are two sets of inner slide plates 5 and fixed suction cups 6. The inner slide plates 5 and fixed suction cups 6 are symmetrically arranged at equal intervals on the inner walls of the two sets of fixed bases 311. There are two sets of outer toothed plates 315. The two sets of outer toothed plates 315 are symmetrically installed at the bottom of the fixed base 311 and both mesh with the outer wall of the gear 314.

[0027] Working principle: During operation, the metal eccentric wheel to be positioned and fixed is first placed between the two sets of inner sliding plates 5 on the inner wall of the fixed base 311. The fixed suction cup 6 fixedly connected to the inner wall of the inner sliding plate 5 is used to initially attract and limit the eccentric wheel to prevent it from shifting during the subsequent positioning process. Then, the motor 318 fixedly connected to the outer wall of the base 2 is started. The output end of the motor 318 drives the pulley 316 fixedly connected to it to rotate. This pulley 316 drives another set of pulleys 316 fixedly connected to the extension end of the inner wall of the gear 314 to rotate synchronously through the transmission belt 317 connected to the outer wall. This causes the gear 314 to rotate around the shaft at the bottom of the outer wall of the connecting plate 1. Since the gear 314 and the two sets of outer tooth plates 315 that are slidably connected to the inner wall of the lower partition 313 mesh with each other, when the gear 314 rotates, it will drive the two sets of outer tooth plates 315 to move inward synchronously along the inner wall of the lower partition 313. During the movement of the outer tooth plates 315, they will drive the fixed seat 311 that is fixedly connected to its top to slide inward synchronously along the outer wall of the connecting plate 1. The wedge-shaped limiting block 312 that is fixedly connected to the inner wall of the fixed seat 311 gradually comes into contact with the outer wall of the eccentric wheel as the fixed seat 311 moves, thus achieving the initial positioning and clamping of the eccentric wheel.

[0028] Meanwhile, depending on the actual thickness of the eccentric wheel to be fixed, the inner toothed plate 319, which is slidably connected to the inner wall of the outer toothed plate 315, can be adjusted to change the tooth spacing. When the eccentric wheel is thicker, the fixing bolt 4 threaded at the top of the outer toothed plate 315 is loosened, and the inner toothed plate 319 is slid outward along the inner wall of the outer toothed plate 315, so that the teeth of the outer toothed plate 315 and the inner toothed plate 319 are misaligned, increasing the tooth spacing after the two are combined to accommodate a thicker eccentric wheel. When the eccentric wheel is thinner, the inner toothed plate 319 is slid inward along the inner wall of the outer toothed plate 315, so that the teeth of the outer toothed plate 315 are misaligned. The teeth of plate 315 and inner tooth plate 319 are brought close together and overlap to reduce the tooth gap, so as to accommodate the thinner eccentric wheel. After adjustment, tighten the fixing bolt 4 so that the extended end of the fixing bolt 4 tightly abuts against the outer wall of inner tooth plate 319, thereby achieving relative fixation between inner tooth plate 319 and outer tooth plate 315. This ensures that inner tooth plate 319 can move synchronously with outer tooth plate 315 and participate in the positioning and fixing of eccentric wheel, further improving the adaptability and positioning stability of eccentric wheels of different sizes. The whole process achieves automated positioning through mechanical transmission, without the need for manual adjustment.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
