Description

Technical Field

[0001] This utility model belongs to the field of gear processing technology, specifically relating to a grinding machine sealing door detection mechanism. Background Technology

[0002] In gear production, grinding machines are mainly used for the precision machining of hardened gear teeth to achieve high dimensional accuracy, form and position tolerances, and low surface roughness. During the grinding process, "droplets" are generated. These droplets are industrial aerosols composed of metal shavings, abrasive dust, and coolant mist; hereinafter referred to as droplets.

[0003] See Figure 1 To prevent droplets from splashing out, the grinding machine includes a housing 10, on which a channel 11 for workpieces to pass through is provided. The channel 11 is L-shaped and is located at the front door and top surface of the housing 10. A track 12 is provided at the bottom of the channel 11, and a sealing door 20 is slidably mounted on the track 12.

[0004] The sliding drive component of the sealed door 20 is a motor. The automatic opening and closing of the sealed door 20 is realized by the motor working in conjunction with the encoder, PLC, etc. That is, the encoder calculates the number of rotations of the motor, thereby calculating the position of the sealed door 20, and then feeding back the position to the PLC to give the "command to open and close the sealed door 20".

[0005] Technical issue: In practice, a fault such as "slippage of sealing door 20" may occur, causing "the PLC to issue a motor stop command before sealing door 20 is fully closed". In this case, droplets will splash out when the sealing door is fully closed. Utility Model Content

[0006] The technical problem this invention aims to solve is: how to design a detection mechanism for the sealing door of a grinding machine to prevent foam from splashing out.

[0007] The specific technical solution of this utility model is as follows: A grinding machine sealing door detection mechanism includes a grinding machine housing, a channel for workpiece passage on the housing, the channel being L-shaped and located on the front and top surfaces of the housing, a track at the bottom of the channel, a sealing door sliding on the track, a support on the housing, a proximity switch on the support, and a detection column on the sealing door that cooperates with the proximity switch.

[0008] The support is located on the top surface of the outer casing, at the top of the detection column sealing door.

[0009] Compared with the prior art, the technical advantage of this utility model is that it is equipped with a mechanical detection mechanism, so even if the "slippage of the sealing door" occurs, it will not affect the accuracy of the inspection. Attached Figure Description

[0011] Figure 2 This is a schematic diagram of the present invention.

[0012] Figure 3 yes Figure 2 A magnified schematic diagram of the detection column. Detailed Implementation

[0013] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 2-3 A grinding machine sealing door detection mechanism includes a grinding machine housing 10, a channel 11 for workpiece passage on the housing 10, the channel 11 being L-shaped and located on the front and top surfaces of the housing 10, a track 12 at the bottom of the channel 11, and a sealing door 20 slidingly mounted on the track 12.

[0015] The outer casing 10 is provided with a support 31, the support 31 is provided with a proximity switch 32, and the sealing door 20 has a detection column 30 that cooperates with the proximity switch 32.

[0016] If the support 31 and the detection column 30 are located on the front of the housing 10, they may interfere with the passage of the workpiece through the channel 11, such as by catching on the operator's clothing. Therefore, if... Figure 3 The support 31 is set on the top surface of the outer casing 10, and the detection column 30 is on the top 21 of the sealing door 20.

[0017] Its working principle is as follows: S1. Placement: After the workpiece is placed, the operator presses the start button.

[0018] S2. Door Closing: After pressing the start button, the PLC communicates with the motor, which then runs to close the door. See below. Figure 2 The sealed door 20 gradually moves to the left.

[0019] S3. Detection: As the sealing door 20 gradually moves to the left, the sealing door 20 is completely closed. At this time, the detection column 30 moves to the proximity switch 32, the proximity switch 32 detects the detection column 30 and sends a signal to the PLC that "the sealing door is completely closed".

[0020] S4. End: After receiving the signal, the PLC communicates with the motor, the motor stops, and the door closing operation ends.

[0021] S5. Processing: At this point, the sealing door is completely closed, and under the command of the PLC, the grinding machine performs normal grinding operations.

[0022] The grinding machine sealing door detection mechanism provided by this utility model has the following significant advantages: S1. This utility model uses a limit switch instead of an encoder for mechanical detection, which detects the true spatial position of the sealed door. Compared with the indirect detection of the encoder, the detection is more accurate.

[0023] S2. The support 31 and the detection column 30 are set on the top surface of the housing 10, so that no protrusion is formed on the front of the housing 10, which facilitates personnel operation.

[0024] For other details, please refer to the existing technology.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
