Description

Technical Field

[0001] The utility model relates to the technical field of threaded hole cleaning, in particular to a guide block threaded hole cleaning device. Background Art

[0002] During the assembly of the guide blocks in the cylinder block of a thermal power product engine, the proper installation process requires the application of anaerobic adhesive to the threaded ends of the ten screws and the threaded holes of the five guide blocks to prevent the guide blocks from loosening during engine operation, which could result in the piston not functioning properly. During the second proper installation, residual anaerobic adhesive from the previous proper installation will remain on the inner walls of the guide block threaded holes. This residual anaerobic adhesive has solidified and has lost its adhesion. If proper installation is performed without cleaning it thoroughly, the adhesion of the newly applied anaerobic adhesive will be greatly reduced, creating a quality risk and affecting the overall quality of the engine's installation and adjustment.

[0003] Current methods for cleaning anaerobic adhesives include: 1. The operator, wearing canvas gloves, grips the guide block and uses a tap of the same diameter to push out any remaining anaerobic adhesive from the inner wall of the threaded hole. This method can only clean one guide block at a time. The main drawbacks of this method are that it requires strong hand strength, is slow to clean, and is time-consuming and labor-intensive. 2. The operator, wearing canvas gloves, grips the guide block and uses a tap of the same diameter to push out any remaining anaerobic adhesive from the inner wall of the threaded hole. This method also only cleans one guide block at a time. The main drawbacks of this method are that the vise's clamping force is difficult to control, potentially damaging or even deforming the guide block. Replacing the guide block is cumbersome, poses quality risks, and is time-consuming.

[0004] CN200970659Y discloses a threaded hole quick cleaning tool, which uses an electric wrench to drive a tap to clean the threaded hole. This method can also only clean one guide block at a time, and how to fix the guide block is also a problem.

[0005] Based on this, a device is needed that can simultaneously clean the threaded holes of multiple guide blocks. Utility Model Content

[0006] In response to the above problems, the utility model provides a guide block threaded hole cleaning device, which places multiple guide blocks that need to be de-glueed into a fixed box at the same time, slides the fixed box and the inner shell body horizontally to make the guide blocks contact with the tap screw, and rotates the tap screw by shaking the handle to push out the glue remaining in the guide block threaded hole, thereby solving the problems of low work efficiency and easy damage to the guide blocks in the original manual hand-held tap cleaning method.

DETAILED DESCRIPTION

[0040] The present invention will be further described in detail below through specific implementations in conjunction with the accompanying drawings.

[0041] Example 1

[0042] like Figure 1 As shown, this embodiment provides a device for cleaning threaded holes of a guide block, comprising: a base 1, two tap screws 5, a drive member and a guide block fixing assembly. The base 1 is made of a steel plate with a thickness of 5 mm, on which a U-shaped outer shell 2 is provided. The outer shell 2 is made of an aluminum alloy and is fixed to the base 1 by nuts and bolts. The guide block fixing assembly consists of an inner shell 3 and a fixing box 4. The inner shell 3 is made of an aluminum alloy and is assembled on the inner slide rail of the outer shell 2. The outer side of the inner shell 3 is connected to the first outer shell 2 by a slide rail, and the inner side of the inner shell 3 is connected to the fixing box 4 by a slide rail, so that the fixing box 4, the inner shell 3 and the outer shell 2 are in a multi-stage nested telescopic structure. As shown Figure 2 As shown, five slots 41 of similar size to the guide block 9 are reserved in the fixing box 4 for fixing the guide block 9. When the fixing box 4 and the inner shell 3 slide along the slide rail, the guide block 9 can be driven to move horizontally.

[0043] The driving member is a crank 72 made of stainless steel, which is connected to the tap screw 5 through a transmission assembly. The tap screw 5 is opposite to the inner housing 3. The transmission assembly is placed inside the outer housing 2. The crank 72 drives the tap screw 5 to rotate, and the rotation of the tap screw 5 is used to clean the threaded hole of the guide block 9. Specifically, Figure 3 The transmission assembly includes: a connecting rod 71, a first gear 73 and a second gear 51. The connecting rod 71 is made of steel, one end of which is fixedly connected to the crank 72 and the other end extends into the outer shell 2. Figure 4-5As shown, there are two tap screws 5 made of high-speed steel with high hardness and long service life. They have the same diameter as the guide block 9 and are supported by two steel brackets 6 arranged along their axial direction. Two second bearings 52, a second positioning nut 53 and a second gear 51 are installed on the tap screw 5. The second bearing 52 is located at the connection with the bracket 6. The second positioning nut 53 is located at the end of the second gear 51 close to the connecting rod 71 and is threadedly connected to the tap screw 5 for positioning the second gear 51. Similarly, after the connecting rod 71 is inserted into the outer shell 2, it is located between the two tap screws 5. A first gear 73, a first positioning nut 75 and two first bearings 74 are provided thereon. The first bearing 74 is located at the connection with the bracket 6. The first gear 73 is meshed with the second gear 51. When the crank 72 is turned counterclockwise, the connecting rod 71 and the first gear 73 rotate counterclockwise, driving the second gear 51 and the tap screw 5 to rotate in the opposite direction. The tap screw 5 rotates clockwise to remove the remaining glue in the threaded hole of the guide block 9.

[0044] Baffle 61 is installed above the bracket 6, and baffle 61 is made of iron sheet to prevent foreign matter from falling into the transmission assembly. Tray 8 is set below the fixed box 4, and tray 8 is slidable, so that it can be removed and the glue in it is cleaned.

[0045] Specifically, if Figure 6 As shown, when in use, the device is securely fixed to a workbench with nuts and bolts, and then several guide blocks 9 to be cleaned are inserted into the fixed box 4. The crank 72 is then shaken counterclockwise to simultaneously move the fixed box 4 and the inner shell 3 along the predetermined slide rail toward the tap screw 5. The tap screw 5 pushes out the glue remaining in the threaded hole of the guide block 9 and drops it into the tray 8, thereby achieving the purpose of cleaning the residual glue in the guide block. After cleaning, simply shake the crank 72 clockwise to slide the fixed box 4 and the inner shell 3 along the predetermined slide rail, then pull out the fixed box 4, and then remove the tray 8 using the handle 81. Finally, remove the cleaned guide block 9 to complete the glue removal work.

[0046] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
