Description

Technical Field

[0001] The utility model relates to the technical field of numerical control processing, and relates to a horizontal transmission structure of a tool rest of a vertical lathe. Background Art

[0002] The tool post of a vertical lathe usually adopts a horizontal rail structure for tool displacement and positioning switching, and relies on the positioning of the processing platform to perform vertical milling and other processing.

[0003] The existing vertical lathe tool holder usually adopts a horizontal transmission structure to switch the movement of the tool holder to the track according to the demand for horizontal displacement. During horizontal transmission, the platform track and the transmission structure use direct contact wheel axles and gear components. During vertical processing, the impact force transmitted between the tool holder and the tool will simultaneously affect the horizontal transmission structure, causing the accuracy of the transmission structure to change. As time goes by, the accumulation of displacement will limit the positioning accuracy of the tool holder and the tool. Utility Model Content

[0004] In view of the above technical problems existing in the prior art, a horizontal transmission structure of a tool holder of a vertical lathe is provided.

[0005] The purpose and effect of the utility model are achieved by the following specific technical means:

[0007] The track plate is a concave plate frame, and a pair of toothed rails are longitudinally symmetrically arranged in the track plate. A roller is rollingly arranged in the middle of the toothed rail, and the roller is matched with the toothed shaft.

[0008] Furthermore, a tool holder seat is inserted into one end of the platform frame, and a bolt opening is provided through one end of the tool holder seat relative to the platform frame.

[0009] Furthermore, both sides of the rail plate member are through openings, and a concave limiting plate is embedded in the through opening at one end of the rail plate member.

[0010] Furthermore, the T-shaped shaft rod is composed of two shaft bodies, and the end surface of one end of the T-shaped shaft rod is larger than the end surface diameter of the gear disc frame.

[0011] Furthermore, a metal fastening ring is sleeved on the butt end of the vertical shaft and the T-axis rod, and the metal fastening ring is rotationally matched with the gear disc frame.

[0012] Furthermore, both ends of the roller shaft are ends of gear plates, and the roller shaft is interference fit with the side wall of the rack through the end.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The horizontal transmission structure of the tool holder of this vertical lathe ensures the horizontal transmission efficiency while realizing the horizontal transmission of the platform frame on the rail plate by relatively matching the toothed shaft and the roller shaft. Compared with the existing direct contact transmission structure, its transmission structure is sequentially coordinated with the transmission motor and the transmission shaft through the T-axis rod, the vertical shaft and the gear plate frame.

[0019] See also Figure 1-3 , the embodiments of the utility model are further described;

[0020] A horizontal transmission structure of a tool rest of a vertical lathe, comprising a platform frame 1 and a track plate 5, wherein the track plate 5 is arranged parallel to one side of the platform frame 1, and a machine handle 3 is embedded in the platform frame 1 on the same side of the track plate 5, a toothed shaft 4 is arranged at one end of the machine handle 3, a vertical shaft 6 is arranged through the toothed shaft 4, and a T-shaped shaft rod 7 is arranged on the vertical shaft 6 extending to the inner side of the machine handle 3, a transmission motor 9 is fixedly arranged between the platform frame 1 and the machine handle 3, a transmission shaft 10 is arranged at one end of the transmission motor 9, and a gear plate frame 8 is sleeved between the transmission shaft 10 and the T-shaped shaft rod 7;

[0021] The track plate member 5 is a concave plate frame, and a pair of racks 11 are longitudinally symmetrically arranged in the track plate member 5 . A roller shaft 12 is rotatably arranged in the middle of the racks 11 , and the roller shaft 12 is matched with the teeth of the toothed shaft 4 .

[0022] The horizontal transmission structure uses the separated platform frame 1 and the track plate member 5 as the fixed end of the tool holder and the horizontal track end respectively. Compared with the existing direct contact shaft transmission method, its transmission structure uses the horizontally matched toothed shaft 4 and roller shaft 12 structure as the horizontal transmission structure between the platform frame 1 and the track plate member 5. In the specific structure, the transmission motor 9 is used to brake the transmission shaft 10, and the gears set in the gear plate frame 8 are used to transmit the transmission between the transmission shaft 10 and the T-axis rod 7. The transmission method is based on the gear set, and then the toothed shaft 4 is rotated through the linkage between the T-axis rod 7 and the vertical shaft 6. The connection between the toothed shaft 4 and the roller shaft 12 is coordinated to make the entire platform frame 1 perform horizontal transmission on the rack 11 of the track plate member 5. Since the platform frame 1 and the track plate member 5 are fixed at both ends, the transmission of the roller shaft 12 and the toothed shaft 4 can make the platform frame 1 perform relative horizontal transmission on the track plate member 5.

[0023] Compared with the existing horizontal transmission structure, this transmission structure uses an indirectly matched toothed shaft 4 and roller shaft 12 structure to reduce the impact of the longitudinal impact force of the tool holder on the horizontal transmission structure, and at the same time uses a relatively axially arranged vertical shaft 6 and T-axis rod 7 structure to ensure the horizontal stability of the horizontal transmission structure, thereby improving the stability of the structure.

[0024] On the basis of the above, a tool holder seat 2 is inserted into one end of the platform frame 1, and a bolt opening is provided through one end of the tool holder seat 2 relative to the platform frame 1. The tool holder seat 2 serves as a tool holder installation structure extended on the platform frame 1, with the bolt opening end as the fixed end of the tool.

[0025] Preferably, both sides of the track plate member 5 are through openings, and a concave limiting plate 13 is embedded in the through opening at one end of the track plate member 5. The limiting plate 13 serves as a limiting structure for the fixed port at one end of the track plate member 5 to prevent the roller shaft 12 from moving out of the track of the track plate member 5.

[0026] Preferably, the T-axis rod 7 is composed of two shaft bodies, one end face of the T-axis rod 7 is larger than the end face diameter of the gear disc frame 8, the T-axis rod 7 has two shaft bodies that are horizontally axially butted together, and the end face at the opposite end is used to longitudinally limit the connection between the toothed disc frame 8 and the shaft body to maintain the horizontal stability of the transmission structure.

[0027] Preferably, a metal fastening ring is provided on the butt end of the vertical shaft 6 and the T-axis rod 7, and the metal fastening ring is rotatably matched with the gear disc frame 8. The fastening ring is used to reinforce the longitudinal connection strength between the vertical shaft 6 and the T-axis rod 7. At the same time, the longitudinal cooperation between the fastening ring and the gear disc frame 8 is utilized to synchronously stabilize the horizontal position of the gear disc frame 8, so as to further ensure the horizontal stability of the transmission structure.

[0028] Preferably, both ends of the roller shaft 12 are gear plate ends, and the roller shaft 12 is interference fit with the side wall of the rack 11 through the ends. The roller shaft 12 is interference fit with the rack 11 through the ends at both ends to limit the horizontal movement direction of the roller shaft 12 to the two sections of the rack 11, so as to improve the horizontal movement stability of the roller shaft 12 and the rack 11 structure.

[0029] The implementation method of the device is to use the platform frame 1 as the fixed structure of the tool holder end, and one end of the track plate 5 as the fixed end of the horizontal track. The two are matched through the toothed shaft 4 and the roller shaft 12 arranged therein to perform horizontal movement and transmission. The transmission method indirectly drives the T-axis rod 7 along the gear plate frame 8 through the movement of the transmission shaft 10, and the axially connected T-axis rod 7 and the vertical shaft 6 are used to synchronously transmit the transmission to the toothed shaft 4. The toothed shaft 4 and the roller shaft 12 are matched and synchronously driven to make the transmission structure perform relative horizontal movement on the rack 11.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
