Description

Technical Field

[0001] The utility model relates to the technical field of machine tool equipment, in particular to a super-finishing machine oil stone limit signaling device. Background Art

[0002] The applicant has previously applied for an angular contact outer ring groove super-finishing machine tool with publication number CN221539371U and a flange double-groove core shaft inner ring groove super-finishing machine tool with publication number CN221248343U. During the super-finishing machining process, the wear of the oilstone is an inevitable phenomenon, and the degree of wear of the oilstone directly affects the machining accuracy and workpiece quality. In order to ensure the stability of the machining process and the consistency of the workpiece quality, it is necessary to monitor the wear of the oilstone in real time and replace the oilstone in time when it is worn to a certain extent.

[0003] Traditional monitoring methods often rely on regular manual inspections, which is not only inefficient but also difficult to ensure the accuracy and timeliness of monitoring. With the development of technology, photoelectric detection has been widely used in oilstone wear monitoring due to its non-contact measurement characteristics. Photoelectric detection devices usually use photoelectric switches. When the oilstone wears to a specified position, the photoelectric switch is turned on, thereby triggering an alarm signal.

[0004] However, in an environment where the machine is running at high speed, the photoelectric detection device faces many challenges. First, due to the high-speed operation and vibration of the machine, the photoelectric switch may find it difficult to accurately detect the wear of the oilstone to a specified position, resulting in inaccurate detection. In addition, the photoelectric switch is more sensitive to interference factors such as ambient light, oil and dust. The superfinishing machine often sprays lubricating oil or grinding fluid onto the oilstone during operation. These liquids interfere with the detection of the photoelectric switch, which further affects the accuracy and stability of the photoelectric detection.

[0005] Therefore, it is necessary to develop an oilstone limit signaling device with a simple structure, low cost, high reliability and suitable for high-speed operation environments. It can accurately capture the oilstone wear to a limited position and send out an alarm signal so that the worn oilstone can be replaced in time to ensure the continuity and stability of the processing process.

[0006] Based on this, the applicant proposed a super-finishing oil stone to limit the signal transmission device to solve the above technical problems. Utility Model Content

[0010] Preferably, an adjuster is provided on the main body, and the adjuster adjusts the position of the trigger so as to adjust the distance between the end of the metal contact wire and the connector.

[0014] Preferably, the regulator includes an electrically controlled retractor, an end portion of the electrically controlled retractor abuts against an upper side of the rotating member, and the rotation of the rotating member is controlled by the retraction and expansion of the electrically controlled retractor.

[0018] Preferably, an arcuate groove is provided on the upper end of the main body, and the arcuate groove is adapted to the connection plate. After the main body is installed on the upper side of the base, the connection plate is matched and connected with the arcuate groove.

[0019] The beneficial effects of the present invention are:

[0020] 1. Improved monitoring accuracy: By utilizing physical contact between metal contacts and connectors, rather than the non-contact measurement of photoelectric detection, the device can more accurately detect when the oilstone has worn to a defined position. This ensures detection accuracy even under high-speed machine operation and vibration, avoiding false alarms or missed alarms that can occur with photoelectric switches due to vibration and liquid interference.

[0021] 2.

This allows ordinary operators to easily perform maintenance and adjustments, and a single adjustment is sufficient for workpieces of the same specification, saving significant time and improving productivity.

[0023] 4. Reduced costs: Compared with complex photoelectric detection devices, this device has a simple structure and low manufacturing cost. At the same time, since it reduces the dependence on precision photoelectric components, it also reduces maintenance costs and operating costs;

[0024] 5. Improve processing quality and efficiency: By monitoring the wear of the oilstone in real time and issuing an alarm signal when the wear reaches a certain level, the device can ensure the continuity and stability of the processing, thereby improving processing quality and production efficiency.

[0034] The following will clearly and completely describe the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments described in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] During the operation of the super finishing machine, the connecting shaft drives the connector to rotate. Because the end of the connector connected to the connecting shaft and the end of the connector connected to the oilstone are not coaxial, the oilstone can make a reciprocating swinging motion. An abutment plate is fixedly provided on the upper side of the connecting shaft, and the abutment plate is L-shaped as a whole. A cylinder is fixedly provided on the upper end of the connector. The telescopic shaft of the cylinder abuts the abutment plate, and the end of the telescopic shaft is hemispherical, which reduces the friction with the abutment plate and is conducive to slippage on the surface of the abutment plate. A resetter is also provided under the connector, and a follower wheel is provided on the upper end of the resetter. When the super finishing machine is running, the cylinder runs and the telescopic shaft abuts the abutment plate. The telescopic shaft extends, and since the connector is rotatably connected to the connecting shaft, when the telescopic shaft extends, due to the limitation of the abutment plate, the connector rotates downward until the oilstone abuts the workpiece. During this process, the resetter is also adjusted to an appropriate position. In one case, the follower wheel abuts against the connector, and during the reciprocating rotation of the connector, the follower wheel follows the rotation to reduce friction. In another case, the resetter descends until it is out of contact with the connector, thereby avoiding friction between the two during the processing process. After the processing is completed, the cylinder runs, the telescopic shaft shortens, and the resetter moves up, pushing the connector to rotate upward and reset, and the oilstone is separated from the workpiece.

[0036] On the basis of the above-mentioned super-finishing machine, by setting up a super-finishing machine oil stone limit signaling device of the utility model, the existing super-finishing machine can be improved and upgraded to ensure that when the oil stone is worn to a limited position during operation, the staff can be reminded to replace it in time.
