Description

Technical Field

[0001] The utility model relates to the field of tool post, in particular to a rotary tool post with four working positions and internal water outlet. Background Technique

[0002] A tool post is a seat for fixing tools, generally divided into a fixed tool post and a rotary tool post. Among them, the fixed tool post fixes the tool during use, while the rotary tool post, also called an electric turret, fixes the tool on the turret, and drives the upper turret to rotate through the drive of a motor, driving the tool to move, adjusting the working position of the tool, so as to realize the switching of different tools.

[0003] In order to solve the heat dissipation problem of the rotary tool post, in the prior art, a spray pipe is installed on the upper turret, and the coolant is transported into the spray pipe through a pipeline, and the coolant is sprayed out through the spray pipe onto the tool for cooling. Related technologies such as the utility model patent with the application number 201720579727.9, a four-station lathe cooling water outlet device, set a waterway fixed plate on the upper turret, the waterway top plate is connected to the water supply pipe, and an L-shaped path water inlet hole is set on the upper turret. When the upper turret rotates, the water outlet hole of the waterway fixed plate will correspond to the L-shaped path water inlet hole, and then it is sprayed out through the spray nozzle. However, the cooling water is directly sprayed onto the surface of the tool, and when drilling the workpiece, the cooling water cannot be sprayed into the hole, and the heat dissipation effect is not very good.

[0004] The utility model patent with the application number 202120967985.0, a tool installation device for a deep hole drilling machine, transports the coolant through a pipeline to the connecting rod, enters the hydraulic tool holder through the connecting rod, and then sprays it into the deep hole through the drill bit.

[0005] After searching by the inventor, although the tools for drilling in the prior art have an internal water outlet structure, it has not been realized in the rotary tool post, and the external water outlet structure is still adopted. In view of this, the inventor has conducted in-depth research and obtained this case. Content of the Utility Model

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figure 1-2, the present utility model provides a rotating tool post with internal water discharge at four stations, which includes a lower tool rest 1. A driving mechanism 11 is installed on the lower tool rest 1, and an upper tool rest 2 is rotatably installed on the lower tool rest 1. During operation, the driving mechanism 11 drives the upper tool rest 2 to rotate on the lower tool rest 1. A coolant pipe 5 and a water spray nozzle 12 are connected to the upper tool rest 2. The connection between the coolant pipe 5 and the upper tool rest 2 is a rotating connection. During operation, the position of the coolant pipe 5 is fixed, and the coolant is transported into the upper tool rest 2 and sprayed out through the water spray nozzle 12 on the side of the upper tool rest 2. This is the prior art. A groove 3 is provided on the side of the upper tool rest 2. A tool holder 8 is fixed in the groove 3. A drill bit 10 is installed in the tool holder 8. The drill bit 10 is provided with spray holes. A joint 7 is provided at the rear end of the tool holder 8. The joint 7 is communicated with the spray holes of the drill bit 10, and a hose 6 is connected between the joint 7 and the water spray nozzle 12.

[0016] During use, the staff snaps the tool holder 8 into the groove 3 on the side of the upper tool rest 2 and fixes it. Then, the water spray nozzle 12 and the joint 7 are connected through the hose 6. During machining, first fix the parts to be processed, and then drive the upper tool rest 2 to rotate through the driving mechanism 11 to realize the switching of the drill bit 10. In the present utility model, the upper tool rest 2 is of a rectangular structure, and the number of tools is correspondingly 4. The types of tools are selectively installed according to the processing requirements. When using the drill bit 10 to drill the parts, the coolant is sprayed out from the water spray nozzle 12 after passing through the cooling pipe 5, and then enters the spray holes of the drill bit 10 through the hose 6 and is sprayed out, so that the coolant can be sprayed into the drill hole to dissipate the temperature in the drill hole.

[0017] Specifically, a limiting groove 9 is provided at the bottom of the groove 3. The length of the limiting groove 9 is equal to the length of the tool holder 8. When installing the tool holder 8, it is slid into the groove 3 through the outer end of the limiting groove 9, and the limiting effect is achieved through the limiting groove 9.

[0018] Furthermore, a fixing bolt 4 is threadedly connected to the upper tool rest 2, and the lower end of the fixing bolt 4 is in close contact with the top of the tool holder 8.

[0019] Even further, a fixing hole 13 is provided at the upper end of the tool holder 8. The lower end of the fixing bolt 4 is inserted into the fixing hole 13. The fixing hole 13 is a frustum-shaped groove structure with a smaller diameter at the lower end and a larger diameter at the upper end. After the lower end of the fixing bolt 4 is inserted into the fixing hole 13, it is in close contact with the inner wall of the fixing hole 13, and the contact is tighter, providing better limiting for the tool holder 8.

[0020] In the description of the present utility model, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0021] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
