Technical Field

[0001] The utility model relates to the field of machine tool processing, in particular to a mechanical faceplate. Background Art

[0002] A mechanical faceplate is a mechanical device, usually used in the field of metal processing, especially for machining rotationally symmetric workpieces on a lathe. It is an accessory installed on a machine tool that can achieve the rotational movement of the workpiece, enabling the tool to perform operations such as cutting, drilling, reaming, and tapping on its surface.

[0003] The traditional processing method is to mill the surface with a three-edge milling cutter head and mill the bottom of the hole with a round blade cutter head. This processing method has the problems of long overhang of the tool bar and boring shaft, weak overall rigidity, and low processing efficiency when machining planetary carrier products with large size specifications. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a mechanical faceplate, which solves the problem of the traditional processing method of milling the surface with a three-edge milling cutter head and milling the bottom of the hole with a round blade cutter head. This processing method has the problems of long overhang of the tool bar and boring shaft, weak overall rigidity, and low processing efficiency when machining planetary carrier products with large size specifications.

[0005] To achieve the above object, the utility model is realized through the following technical solutions: A mechanical faceplate includes a connecting cylinder. A mechanical push rod is disposed through the middle inside the connecting cylinder. The fixed end of the mechanical push rod is fixedly connected to the connecting cylinder. The free end of the mechanical push rod is fixedly connected to a boring head. A faceplate head is disposed at one end of the boring head away from the mechanical push rod. A slide plate is disposed on the other side of the faceplate head. An end face tool holder is installed on the side of the slide plate away from the faceplate head. A transfer plate is disposed at the front end of the connecting cylinder, and the front side of the transfer plate is attached to the rear side of the spindle milling head.

[0006] Preferably, the middle part of the connecting cylinder penetrates through a planetary carrier, and a cavity is provided at the position of the planetary carrier where the faceplate head is located.

[0007] Preferably, inner locking bolts are threadedly connected to the four corners of the outer circle at the connection position between the transfer plate and the spindle milling head.

[0008] Preferably, outer locking bolts are threadedly connected to the four corners of the inner circle at the connection position between the transfer plate and the spindle milling head.

[0009] Preferably, a taper shank is provided at the connection position between the faceplate head and the boring head.

[0010] Preferably, the end face tool holder (7) has two upper and lower blades. Advantageous Effects

[0011] The present utility model provides a mechanical faceplate. Compared with the prior art, it has the following beneficial effects:

[0012] In the present utility model, through the arranged mechanical push rod, the overhanging lengths of the tool bar and the boring spindle can be significantly shortened, thereby reducing the problem of insufficient rigidity caused by long overhang, improving the overall rigidity during the machining process. In addition, the connecting cylinder is installed on the spindle milling head through the adapter plate, and the mechanical faceplate is installed on both the milling head and the boring head of the machine tool spindle at the same time. When the mechanical faceplate is installed on both the milling head and the boring head at the same time, the supporting points on both sides (the milling head and the boring head) jointly bear the force and vibration during machining. Therefore, the rigidity of the composite tool bar is greatly enhanced, thereby improving the overall stability;

In the present utility model, through the arranged adapter plate, the connecting cylinder passing through the planet carrier, and the threaded connection of the internal and external locking bolts, the connection stability between the adapter plate and the spindle milling head is enhanced, reducing looseness and displacement caused by vibration or machining force. The design of the connecting cylinder and the adapter plate, as well as the setting of the internal and external locking bolts and the taper shank, enable the mechanical faceplate to be quickly and stably installed on the machine tool spindle, shortening the preparation time before machining and improving the machining efficiency.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 - 3, the present utility model provides two technical solutions, specifically including the following embodiments: Embodiment

[0021] The mechanical facing head includes a connecting cylinder 1. A mechanical push rod 10 is disposed through the middle inside the connecting cylinder 1. The fixed end of the mechanical push rod 10 is fixedly connected to the connecting cylinder 1. The free end of the mechanical push rod 10 is fixedly connected to a boring head 4. A facing head 5 is disposed at one end of the boring head 4 away from the mechanical push rod 10. A slide plate 6 is disposed on the other side of the facing head 5. An end face tool holder 7 is installed on the side of the slide plate 6 away from the facing head 5. The slide plate 6 is used to install the end face tool holder 7. The end face tool holder 7 is a CAPTO quick-change interface structure. The end face tool holder 7 has two upper and lower blades. A transfer disk 2 is disposed at the front end of the connecting cylinder 1. The front side of the transfer disk 2 is attached to the rear side of the spindle milling head 3. The mechanical push rod 10 can significantly shorten the overhang length of the tool rod and the boring shaft, thereby reducing the problem of insufficient rigidity caused by long overhang, and improving the overall rigidity during the machining process. In addition, the connecting cylinder 1 is installed on the spindle milling head 3 through the transfer disk 2. The mechanical facing head is simultaneously installed on the milling head and the boring head 4 of the machine tool spindle. When the mechanical facing head is simultaneously installed on the milling head and the boring head 4, the support points on both sides, namely the milling head and the boring head 4, jointly bear the force and vibration during machining. Therefore, the rigidity of the composite tool rod is greatly enhanced, thereby improving the overall stability. In the traditional machining method, the overhang length of the tool is relatively long, which may cause the tool to be prone to bending and vibration during machining. However, the design of the mechanical facing head makes the tool system more compact, reduces the overhang length, and thus reduces the insufficient rigidity caused by the overhang.

[0022] During operation, attach the front side of the transfer disk 2 to the rear side of the spindle milling head 3 to ensure the stable connection between the transfer disk 2 and the spindle milling head 3. Start the machine tool and check the operation of the facing head system to ensure that there is no abnormality in each component. According to the machining requirements, use the end face tool holder 7 to perform turning machining on the upper and lower planes, or replace the end face tool holder 7 to use a round nose tool holder to machine the bottom surface of the hole and the root R. Embodiment

[0023] On the basis of Embodiment 1, the middle part of the connecting cylinder 1 penetrates through the planet carrier 8. A cavity 9 is provided at the position of the planet carrier 8 where the faceplate head 5 is located. Inner locking bolts 11 are threadedly connected to the four corners of the outer circle at the connection position between the adapter plate 2 and the spindle milling head 3, and outer locking bolts 12 are threadedly connected to the four corners of the inner circle at the connection position between the adapter plate 2 and the spindle milling head 3. A taper shank 13 is provided at the connection position between the faceplate head 5 and the boring head 4. Through the connecting cylinder 1 penetrating the planet carrier 8 and the threaded connection of the inner and outer locking bolts 12, the connection stability between the adapter plate 2 and the spindle milling head 3 is enhanced, and loosening and displacement caused by vibration or machining force are reduced. The design of the connecting cylinder 1 and the adapter plate 2, as well as the setting of the inner and outer locking bolts 12 and the taper shank 13, enable the mechanical faceplate to be quickly and stably installed on the machine tool spindle, shortening the preparation time before machining and improving the machining efficiency.

[0024] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the application shall be included in the protection scope of the present application.
