Technical Field

[0001] This utility model relates to the field of power tool holder technology, specifically a power tool holder for machine tool processing. Background Technology

[0002] A powered tool holder refers to a tool holder mounted on a powered tool turret and driven by a servo motor. This type of tool holder is generally used on mill-turning machines, and a few can also be used on machining centers with powered tool turrets. It is a connecting device between small CNC mill-turning machines and rotary cutting tools, clamping the tool and transmitting machine tool power to the rotary cutting tool.

[0003] According to a public announcement of a power tool holder for CNC machine tools (Announcement No.: CN219562286U), the above application achieves a good sealing effect by sequentially installing the end cover and cover plate on the spindle, and filling the packing area formed between the end cover, cover plate, and main housing with sealing packing.

[0004] However, when the sealing packing needs to be replaced due to wear, it is located in the packing area formed between the end cover, cover plate and main housing. Multiple parts such as the end cover and cover plate need to be disassembled for replacement, which is cumbersome and increases maintenance costs and downtime. Utility Model Content

[0005] The purpose of this utility model is to provide a power tool holder for machine tool processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power tool holder for machine tool processing, comprising a housing, an end cover, a cover plate, and a shaft. The shaft is rotatably connected through and to the side walls of the housing, the end cover, and the cover plate. The end cover has a filling area surrounding the shaft, and the filling area has a strip groove. The filling area is filled with sealing filler. The cover plate is in contact with the end face of the end cover. The side wall of the cover plate has an insertion hole, and a connecting rod is inserted into the insertion hole. The connecting rod is inserted into the strip groove, and a bending plate is hinged to one end of the connecting rod. The bending plate is in contact with the end face of the cover plate.

[0007] Preferably, the end face of the end cap is provided with a limiting component, the limiting component includes a groove, the groove is formed on the end face of the end cap, a movable seat is slidably connected inside the groove, a ring is fixedly connected to the side wall of the movable seat, and multiple sets of arrayed L plates are fixedly connected to the side wall of the ring, the L plates are in contact with the side wall of the bending plate.

[0008] Preferably, the side wall of the movable seat has a through hole, and a positioning rod is slidably connected in the through hole, the end of the positioning rod being fixedly connected to the inner wall of the groove.

[0009] Preferably, the movable seat is elastically connected to the inner wall of the groove by a return spring.

[0010] Preferably, a collar is fixedly connected to the other end of the connecting rod, and the collar contacts one end of the sealing packing located inside the packing area.

[0011] Preferably, the diameter of the ring is larger than the diameter of the cover plate.

[0012] Compared with the prior art, this utility model provides a power tool holder for machine tool processing, which has the following beneficial effects:

[0013] 1. The power tool holder for this machine tool only requires rotating the ring in the opposite direction to misalign the L-plate with the bending plate, and rotating the bending plate to a horizontal position to remove the cover plate. Then, pulling the connecting rod to drive the collar can remove the sealing packing. This simplifies the replacement steps, shortens the replacement time, improves work efficiency, and also reduces maintenance costs.

[0014] 2. The power tool holder for machining this machine tool guides the moving seat through the positioning rod, enabling the moving seat to move stably within the groove. The return spring provides elastic support for the moving seat, ensuring that the ring can drive the L-plate to tightly press against the bent plate, thus achieving reliable fixation of the cover plate. While ensuring the fixation effect, it also allows for convenient release of the fixation when replacing the sealing packing. Attached Figure Description

[0019] like Figures 1-3As shown, this utility model provides a technical solution: a power tool holder for machine tool processing, including a housing 1, an end cover 2, a cover plate 3, and a shaft 4. The shaft 4 is rotatably connected to the side walls of the housing 1, the end cover 2, and the cover plate 3. The end cover 2 has a filling area 21 that surrounds the shaft 4 inside. The filling area 21 has a strip groove 22 inside. The filling area 21 is filled with sealing filler 23. The cover plate 3 is in contact with the end face of the end cover 2. The cover plate 3 assists the end cover 2 in sealing the tool holder and at the same time provides a certain constraint on the internal sealing filler 23.

[0020] like Figures 1-3 As shown, the side wall of the cover plate 3 has an insertion hole 31, and a connecting rod 32 is inserted into the insertion hole 31. The connecting rod 32 is inserted into the inside of the strip groove 22. One end of the connecting rod 32 is hinged to a bending plate 34, which fits against the end face of the cover plate 3. When the bending plate 34 is rotated to a horizontal position with the connecting rod 32, the insertion hole 31 allows the connecting rod 32 to pass through the bending plate 34. When the bending plate 34 is rotated to a perpendicular position with the connecting rod 32, the bending plate 34 fits against the surface of the cover plate 3. Through cooperation with the limiting component 5, the cover plate 3 is fixedly fixed. The other end of the connecting rod 32 is fixedly connected to a collar 33, which contacts the end of the sealing packing 23 located inside the packing area 21. After the cover plate 3 is opened, the connecting rod 32 drives the collar 33 to move, thereby removing the sealing packing 23 inside the packing area 21, which facilitates the quick replacement of the sealing packing 23.

[0021] like Figures 1-3 As shown, a limiting component 5 is provided on the end face of the end cap 2. The limiting component 5 includes a groove 51, which is formed on the end face of the end cap 2. A movable seat 52 is slidably connected inside the groove 51. A through hole is formed on the side wall of the movable seat 52, and a positioning rod 53 is slidably connected in the through hole. The end of the positioning rod 53 is fixedly connected to the inner wall of the groove 51. The positioning rod 53 is used to guide the movable seat 52, so that the movable seat 52 moves stably inside the groove 51. The movable seat 52 is elastically connected to the inner wall of the groove 51 by a return spring 54. A ring 55 is fixedly connected to the side wall of the movable seat 52. The return spring 54 provides elastic support for the movable seat 52, so that the movable seat 52 drives the ring 55 to rotate circumferentially on the end face of the end cap 2.

[0022] like Figures 1-3As shown, the diameter of the ring 55 is larger than the diameter of the cover plate 3. Multiple arrays of L-plates 56 are fixedly connected to the sidewall of the ring 55. The L-plates 56 are in contact with the sidewall of the bent plate 34. The cover plate 3 is located within the inner diameter of the ring 55. During the rotation of the ring 55, the L-plates 56 contact the sidewall of the vertically oriented bent plate 34, ensuring a tight fit between the bent plate 34 and the cover plate 3, thus fixing the cover plate 3. When the sealing packing 23 needs to be replaced, the ring 55 is rotated in the opposite direction, compressing the return spring 54, causing the L-plates 56 and the bent plate 34 to shift, allowing the cover plate 3 to be removed.

[0023] In this utility model, when it is necessary to replace the sealing packing 23, the ring 55 is rotated in the opposite direction. At this time, the return spring 54 is compressed, and the L plate 56 on the ring 55 is misaligned with the bending plate 34. When the bending plate 34 is rotated to a state that is horizontal with the connecting rod 32, the connecting rod 32 and the bending plate 34 can pass through the insertion hole 31, thereby removing the cover plate 3. By pulling the connecting rod 32, the collar 33 is moved, thereby smoothly removing the sealing packing 23 in the packing area 21.

[0024] After replacing the new sealing packing 23, when replacing the new sealing packing 23, put the connecting rod 32 and the collar 33 back into the packing area 21 and fill it with the new sealing packing 23. Reinstall the cover plate 3 back in its original position. Rotate the bent plate 34 to a position perpendicular to the connecting rod 32 and make it fit against the surface of the cover plate 3. Use the elastic force of the return spring 54 to make the ring 55 drive the L plate 56 to press the bent plate 34, thereby fixing the cover plate 3.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
