Description

Technical Field

[0001] This utility model relates to the field of machine tool equipment, and in particular to a cleaning device for the deep holes of parts after they have been machined by a machine tool. Background Technology

[0002] After machining deep-hole parts, iron filings cannot be discharged and accumulate in the deep holes, causing inconvenience to subsequent machining. The traditional method is to use an air gun to deliver high-pressure airflow into the deep holes to discharge the iron filings and achieve the purpose of cleaning the deep holes. The deeper the hole, the more difficult it is for the airflow to clean the inside of the deep hole. Utility Model Content

[0003] To solve the current problem of cleaning deep-hole parts, the technical solution adopted by this utility model is as follows:

[0004] A deep-hole parts cleaning device for machine tools includes a sleeve, a push rod that can move and extend along the axial direction of the sleeve is installed inside the sleeve, a cylinder that drives the push rod to move is installed on the outer wall of the sleeve, a channel is provided inside the push rod, a spray head communicating with the channel is provided at one end of the push rod, a set of spray nozzles are arranged circumferentially on the spray head, a connecting plate is provided between the push rod and the cylinder, a through groove is provided on the sleeve along the axial direction for connecting the connecting plate to the push rod and allowing the connecting plate to move along the axial direction of the sleeve, and an inlet communicating with the channel is provided on the push rod for cleaning fluid or airflow to enter the channel.

[0005] Furthermore, the sleeve is also provided with a pair of limit switches that limit the extension and retraction range of the push rod, and the push rod is provided with a lever that moves with the push rod and is located between the limit switches to trigger the limit switches.

[0006] Furthermore, a flange for fixing the sleeve is provided at the end of the sleeve (1).

[0007] The above technical solution uses a cylinder to drive a push rod, which in turn moves the spray head within the deep hole part. As the push rod moves within the deep hole, the spray head cleans the inner wall of the deep hole. Since the channel inside the push rod can carry both cleaning fluid and airflow, it can effectively remove iron filings from the deep hole using the cleaning fluid and remove residual cleaning fluid using high-pressure airflow, thus thoroughly cleaning the deep hole.

[0008] Figure 1 This is a schematic diagram of the cleaning device.

[0009] Figure 2 This is a sectional view of the cleaning device in practical condition. Detailed Implementation

[0010] like Figure 1 and2 The deep hole cleaning device for machine tools shown includes a sleeve 1, a push rod 2 inside the sleeve 1, and a cylinder 3 outside the sleeve 1. The cylinder 3 drives the push rod 2 to move axially within the sleeve 1. Specifically, a through groove 1-1 arranged axially along the sleeve 1 is provided on the side wall of the sleeve 1. A connecting plate 5 is fixed at the telescopic end of the cylinder 3. The connecting plate 5 is connected to the push rod 2 through the through groove 1-1. When the cylinder 3 drives the connecting plate 5, it can drive the push rod 2 to move axially along the sleeve 1, so that the push rod 2 can telescopically move within the sleeve 1.

[0011] A spray head 4 is installed at one end of the push rod 2 that extends out of the sleeve 1. A set of spray nozzles 4-1 are arranged axially on the spray head 4. A channel 2-1 is provided inside the push rod 2, which is connected to the spray head 4. By supplying cleaning fluid into the channel 2-1 and spraying it out through the spray nozzles 4-1, the cleaning fluid can clean the impurities in the deep hole when the push rod 2 moves the spray head 4 in the deep hole B. It can also supply high-pressure airflow into the channel 2-1 and then supply high-pressure airflow into the deep hole through the spray nozzles 4-1 to clean the deep hole, further improving the cleaning effect and effectively cleaning the residual cleaning fluid in the deep hole, making the cleaning more thorough.

[0012] In order to deliver cleaning fluid or high-pressure airflow into channel 2-1, an inlet 6 connected to channel 2-1 is provided at the tail of push rod 2, through which the cleaning fluid or high-pressure airflow is delivered into channel 2-1.

[0013] To ensure that the push rod 2 extends and retracts within a reasonable range, a pair of limit switches 7 are also provided on the sleeve 1, and a paddle 8 is provided on the push rod 2. The paddle 8 is connected to the push rod 2 through the through groove 1-1. When the push rod 2 moves, it drives the paddle 8 to move together, so that when the paddle 8 moves to the position of the limit switch 7, it can trigger the limit switch 7 at that position, so that the cylinder 3 stops moving or drives the push rod 2 to move in the opposite direction, ensuring that the spray head 4 moves within a reasonable range.

[0014] To facilitate the installation of the cleaning device into the machine tool, a flange 1-2 is provided at the end of the sleeve 1. The entire cleaning device can be installed into a suitable position in the machine tool through the flange 1-2 as needed, or it can be installed on a robotic arm and driven by the robotic arm to perform the cleaning operation.
