Description

Technical Field

[0001] This utility model relates to the technical field of machine tool drive devices, specifically a drive device for machine tool processing. Background Technology

[0002] Machine tool processing is a process that uses machine tools to cut, shape, and perform other processing operations on metals or other materials. In order to ensure processing accuracy and surface quality, it is necessary to drive the worktable to rotate so that it can perform linear motion, rotary motion, or other complex motion forms according to processing requirements, which requires the use of a drive device.

[0003] Currently, most machine tool processing uses drive devices that need to be turned off when processing workpieces on the machining table. However, there are gaps between the transmission structures of the drive device. As a result, when the machine tool is cutting the workpiece, it may drive the rotary table to rotate, affecting the accuracy of the machine tool in processing the workpiece. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 - Figure 7 As shown, in this embodiment, a drive device for machine tool processing includes: a housing 1; a mounting groove 7 formed on the housing 1; a worm gear 3 disposed inside the housing 1; a brake end cover 4 fixed to the mounting groove 7 by bolts; a brake piston 15 movably disposed inside the brake end cover 4; a fixing bolt 8 fixed to the mounting groove 7; a brake pad 11 fixedly connected to the fixing bolt 8; an outer brake pad 10 disposed on the fixing bolt 8; and an inner brake pad 12 disposed on the fixing bolt 8. The brake piston 15, the outer brake pad 10, and the brake pad 11 are configured to cooperate to restrict the rotation of the worm gear 3 inside the housing 1.

[0024] Hydraulic oil is introduced into the brake end cover 4, which pushes the brake piston 15, causing the outer brake pad 10 and inner brake pad 12 to undergo elastic deformation. The outer brake pad 10 rubs against the inner brake pad 12 and the brake pad pad 11, thus achieving braking and preventing the workpiece from rotating on the rotating table when the machine tool is cutting the workpiece, thereby improving the machining accuracy of the workpiece. A hydraulic oil connecting pipe is connected to one side of the brake end cover 4, and a hydraulic oil connecting pipe is also connected to one side of its outer shell 1. The mounting groove 7 is divided into a mounting part and a braking part. The mounting part is used to install and fix the brake end cover 4, and the braking part is used to install the outer brake pad 10, inner brake pad 12 and brake pad pad 11.

[0025] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, it also includes: brake adjustment shim 9, which is fixedly connected to the worm gear 3 by bolts.

[0026] The gap between the outer brake pad 10 and the inner brake pad 12 can be adjusted by using the brake adjusting shim 9. During adjustment, the brake end cover 4, brake piston 15 and oil seal 5 need to be removed, and the bolts on the brake adjusting shim 9 can be rotated to adjust the gap between the outer brake pad 10 and the inner brake pad 12.

[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, it also includes: an oil seal 5, which is installed inside the brake end cover 4.

[0028] The design of oil seal 5 prevents hydraulic oil leakage, avoids pressure drop in brake components, and makes the brake design longer and the braking force weaker.

[0029] like Figure 6 As shown, it also includes: an oil drain groove 17, which runs through the brake adjusting shim 9.

[0030] Through the structural design of the drain groove 17, the hydraulic oil used to inject into the brake end cover 4 flows into the outer shell 1 through the drain groove 17.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes: a drive motor 2, which is fixedly connected to the housing 1; and a worm gear 16, which is disposed inside the housing 1 and meshes with the worm wheel 3.

[0032] By turning on the drive motor 2, the worm 16 drives the worm wheel 3 to rotate, causing the worktable 6 to rotate and the workpiece on the machine tool to rotate. The output end of the drive motor 2 is not directly connected to one end of the worm 16, but is connected through a driven gear and a driving gear.

[0033] like Figure 4 and Figure 5 As shown, it also includes: a turntable bearing 13, which is mounted on the worm gear 3; and a turntable base 14, which is fixed to the outer casing 1 by bolts, and the inner wall of the turntable base 14 is engaged with the outer surface of the turntable bearing 13.

[0034] The worm gear 3 is stably mounted on the housing 1 by the cooperation of the turntable bearing 13 and the turntable base 14, ensuring the stability of the worm gear 3 when it rotates.

[0035] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the workbench 6 is fixedly connected to one end of the worm gear 3.

[0036] The worktable 6 is used to install the fixture, which causes the drive motor 2 to rotate and drive the tool fixed on the worktable 6 to rotate. The worktable 6 and the worm gear 3 are fixedly connected by multiple bolts.

[0037] This utility model provides a drive device for machine tool processing, the specific working principle of which is as follows:

[0038] When the machine tool processes the workpiece, the workpiece is first clamped on the worktable 6, the drive motor 2 is turned on, and the worktable 6 is rotated. The angle of the workpiece on the worktable 6 is adjusted. When cutting the workpiece, hydraulic oil is introduced into the brake end cover 4. The hydraulic oil pushes the brake piston 15, causing the outer brake pad 10 and the inner brake pad 12 to undergo elastic deformation. The outer brake pad 10 rubs against the inner brake pad 12 and the brake pad pad block 11 to achieve braking, and the workpiece is processed on the machine tool.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
