Description

Technical Field

[0001] This utility model is a simple transmitter structure. Background Technology

[0002] Currently, in industrial machinery such as presses and punch presses, signaling mechanisms are often used to acquire displacement or rotation information in order to monitor the real-time operating status of moving parts (such as sliders and crankshafts). These signaling structures are typically attached to the main drive system and transmit motion signals to sensing elements (such as limit switches or encoders) via mechanical linkage, achieving feedback control of the equipment's operating status. In existing designs, the signaling components are generally installed on the side or back of the machine body. Mounting holes are machined in the machine body panel to fix the signaling structure in a suitable position, thereby achieving mechanical connection with the internal motion system of the equipment.

[0003] Specifically, a typical signal transmission system usually includes a large gear fixed on a main shaft or eccentric wheel. This gear drives a bevel gear to rotate, which in turn rotates a subsequent drive shaft. This causes a cam mounted at the end of the drive shaft to rotate, triggering a downstream mechanical limit mechanism or outputting an analog signal to the electronic control system. The entire structure involves multiple mechanical transmission components, such as sprockets, chains, tensioners, and cam controllers. The relative positions and clearances of each component significantly affect the overall accuracy and response time of the system.

[0004] However, while achieving basic signal transmission functionality, the aforementioned structure also has significant limitations. First, the chain drive system is highly susceptible to issues related to installation accuracy and tension, making it prone to problems such as chain slippage, tooth skipping, or response lag, thus affecting signal transmission accuracy and stability. Second, this type of mechanism occupies a large space and requires significant modifications to the machine structure, increasing design difficulty and assembly complexity in areas such as panel openings, component placement, and maintenance access. Furthermore, the sprocket and chain structure is subject to wear, requiring regular maintenance and replacement, increasing operating costs and equipment downtime, which is detrimental to efficient and stable production. Utility Model Content:

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a simple transmitter structure.

[0006] A simple transmitter structure includes a flange, a drive shaft, a cam, a mounting base, and an encoder. The flange is installed in an opening in the machine body. The drive shaft rotatably passes through the flange. A gear is fixedly sleeved at one end of the drive shaft, and a cam is fixedly sleeved at the other end. The drive shaft is connected to the encoder via a connecting shaft. The encoder is mounted on the mounting base, which includes a connecting plate and a mounting cylinder. The surface of the connecting plate has a through hole, and the mounting cylinder is fixed at the through hole with its opening aligned with the through hole. A clearance hole is provided at the bottom of the mounting cylinder. The connecting shaft and the cam are located inside the mounting cylinder, and the encoder is mounted on the outside of the mounting cylinder.

[0007] Furthermore, the drive shaft is rotatably connected to the flange via bearings, with the outer ring of the bearing connected to the inner wall of the flange and its inner ring connected to the outer wall of the drive shaft.

[0008] Furthermore, the connecting plate is connected to the flange by bolts.

[0009] Furthermore, the connecting plate and the mounting cylinder are connected by welding.

[0010] Furthermore, the flange is bolted to the machine body.

[0011] Beneficial Effects: Compared with existing technologies, the simplified transmitter structure provided by this utility model has several advantages, including compact structure, easy installation, and stable operation. Firstly, by integrating and optimizing the design of traditional sprockets, chains, and cam controllers, cumbersome intermediate mechanical connections are eliminated, effectively reducing the number of parts. This not only lowers overall manufacturing and maintenance costs but also improves assembly efficiency. Compared to existing transmitter systems, this structure eliminates the need for additional holes in the machine body, avoiding problems such as reduced structural strength and compromised sealing, resulting in a simpler and more aesthetically pleasing appearance.

[0012] Secondly, by directly connecting the encoder to the drive shaft, the response speed and accuracy of the signal output can be effectively improved, avoiding positional deviation or control delay caused by intermediate transmission errors, and enhancing the system's adaptability in high-frequency, high-precision working scenarios. Simultaneously, the flange provides stable support to the drive shaft through bearing limits, ensuring the stability and reliability of torque transmission during the transmission process, fundamentally improving the service life and anti-interference capability of the signal transmitting mechanism.

[0013] Furthermore, the mounting base of this invention adopts an integrated structure design of connecting plate and mounting cylinder, achieving precise positioning through through-hole alignment. Simultaneously, the provided clearance holes further enhance structural compatibility and assembly flexibility, meeting the integration requirements of various equipment models. Therefore, this structure not only achieves efficient integration of signal transmission functions but also provides a more stable, convenient, and economical sensing structure solution for modern press control systems.

[0017] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0018] A simple transmitter structure includes a flange, a drive shaft, a cam, a mounting base, and an encoder. The flange is installed in an opening in the machine body. The drive shaft rotatably passes through the flange. A gear is fixedly sleeved at one end of the drive shaft, and a cam is fixedly sleeved at the other end. The drive shaft is connected to the encoder via a connecting shaft. The encoder is installed on the mounting base, which includes a connecting plate and a mounting cylinder. The surface of the connecting plate has a through hole, and the mounting cylinder is fixed at the through hole with its opening aligned with the through hole. The bottom of the mounting cylinder has a clearance hole. The connecting shaft and the cam are located inside the mounting cylinder, and the encoder is installed on the outside of the mounting cylinder.

[0019] In traditional press signal transmission structures, a mounting flange is typically installed through an opening on the side of the press body. The flange houses a drive shaft for rotation, which is connected to the crankshaft system. A large gear drives a bevel gear, which in turn drives the drive shaft to output a rotational signal. This invention simplifies and innovates upon this, omitting complex components such as sprockets, tensioners, and cam controllers found in traditional structures. Instead, a modified flange is used to directly mount the drive shaft. A cam is fixed to the other end of the drive shaft via a key, and the cam's rotational signal is transmitted to the encoder via a connecting shaft. The encoder is fixed to an encoder holder, which is part of the mounting base, and securely mounted to the flange surface using bolts or welding, ensuring structural rigidity and precision. Simultaneously, clearance holes are provided inside the mounting cylinder to avoid interference with the connecting shaft structure, ensuring installation accuracy and smooth transmission.

[0020] This invention significantly simplifies the number of components and installation complexity of traditional signal transmitting mechanisms. It eliminates the need for additional openings in the machine panel and removes several conventional components such as chains, sprockets, and cam controllers, significantly reducing manufacturing and maintenance costs. The encoder is directly coupled to the drive shaft via a connecting shaft, avoiding error accumulation from intermediate links and significantly improving the accuracy and stability of the signal output. Furthermore, the flange provides reliable support for the drive shaft, and bearings provide limiting, ensuring that the crankshaft transmission accuracy is not affected during operation. The overall structure is aesthetically pleasing and compact, contributing to improved overall equipment assembly efficiency and ease of maintenance.

[0021] In this embodiment, the drive shaft is rotatably connected to the flange via a bearing. The outer ring of the bearing is connected to the inner wall of the flange, and its inner ring is connected to the outer wall of the drive shaft.

[0022] In this embodiment, the connecting plate is connected to the flange by bolts.

[0023] In this embodiment, the connecting plate and the mounting cylinder are connected by welding.

[0024] In this embodiment, the flange is bolted to the machine body.
