Description

Technical Field

[0001] The present invention relates to a drilling machine tool, and more particularly to a numerically controlled multi-axis radial facing milling and drilling machine tool. Background Art

[0002] Common machine tools include special-purpose machine tools and general-purpose machine tools. General-purpose machine tools can process various types of workpieces and have strong versatility, but their processing efficiency is low; special-purpose machine tools are suitable for processing specific parts, have poor versatility, but high processing efficiency.

[0003] Patent Application No. CN2017107957845 discloses an invention patent for a full-direction rotation drilling and processing machine tool fixture for disc-shaped workpieces. This patent shows a common design form of this type of machine tool. The transmission system of the entire device consists of a three-axis coordinate system, and the three axes are the X-axis, Y-axis, and Z-axis respectively, and any two of the coordinate axes are perpendicular to each other. The processing of any point on the workpiece is achieved through the mutual cooperation of the X-axis, Y-axis, and Z-axis.

[0004] The disadvantages of this type of machine tool are as follows: (1) When the processed parts are relatively hard, the traditional three-axis coordinate system cannot provide sufficient bearing capacity, especially in the Z-axis direction; (2) Unidirectional cutting makes the cutting force borne by the workpiece uneven, easily causing deformation of the fixture, affecting the accuracy of the processed parts and the service life of the fixture.

[0005] Based on this, it is necessary to improve the special-purpose machine tool for drilling. Summary of the Invention

[0006] In order to overcome the deficiencies existing in the prior art, the present invention provides a numerically controlled multi-axis radial facing milling and drilling machine tool.

[0007] To achieve the above object, a numerically controlled multi-axis radial facing milling and drilling machine tool disclosed by the present invention includes: A drilling terminal, which is installed on a slide table; The slide table, which at least includes a first slide base, a second slide base, and a third slide base that are sequentially slidably connected. Define the sliding direction of the first slide base as the first direction, define the sliding direction of the second slide base as the second direction, define the sliding direction of the third slide base as the third direction, and set the included angle between the first direction and the second direction as A, 0° < A < 90°, and the third direction is perpendicular to the first direction and the second direction; A fixture, which is arranged on one side of the drilling terminal.

[0008] Preferably, it further includes a base. The first slide base is slidably connected to the base and reciprocally slides along the first direction; the second slide base is slidably connected to the first slide base and reciprocally slides along the second direction; the third slide base is slidably connected to the second slide base and reciprocally slides along the third direction.

[0009] Preferably, the sliding table and the base are defined as a loading terminal, and there is at least one such loading terminal.

[0010] Preferably, there are at least two such loading terminals, and at least two of the loading terminals are arranged in a circumferential array centered on the fixture position.

[0011] Preferably, the base includes a base platform and a turntable, the turntable is rotatably connected to the base platform, and the turntable reciprocally rotates centered on the fixture position.

[0012] Preferably, the drilling terminal includes a tool magazine and a support base, the tool magazine is rotatably connected to the support base, and tool positions for fixing tools are arranged in a circumferential array on the tool magazine.

[0013] The fixture includes a clamping terminal and a loading seat, and the clamping terminal is rotatably connected to the loading seat.

[0014] The present invention has the following technical effects: (1) One of the creative points of the present invention is that the loading terminal can reciprocally rotate centered on the fixture, having a higher processing freedom degree. The beneficial effects of such a design are as follows: 1) Process holes such as those shown in the attached Figure 1 can be processed by means of swinging.

[0015] 2) Holes with mirror-image distribution and non-mirror-image distribution can be processed for the workpiece simultaneously.

[0016] (2) Another creative point of the present invention is that the traditional vertically oriented Z-axis is changed to an inclined second direction. The beneficial effects of such a design are as follows: 1) Provide better support for the drilling terminal. Assume that in a traditional drilling machine tool, the force borne by the vertically oriented Z-axis is F, then the entire F is loaded onto the transmission lead screw of the z-axis; while in this device, F is decomposed into a first component force F*cosθ perpendicular to the second direction and a second component force F*sinθ parallel to the second direction, where only the second component force is borne by the transmission lead screw in the second direction, and the first component force is borne by the first sliding seat.

[0017] 2) The drilling terminal has better transmission accuracy on the Z-axis. Assume that in a traditional drilling machine tool, when the drilling terminal moves a distance A in the vertical direction, this distance A is driven by the transmission lead screw in the Z-axis direction; in this device, if the same distance A is moved in the vertical direction, then the distance driven by the transmission lead screw in the second direction is A / sinθ, with higher accuracy.

Specific embodiments

[0020] The principles and features of the present invention will be described below in conjunction with embodiments; the examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0021] A numerically controlled multi-axis radial facing milling and drilling machine tool includes a cutting terminal 100, a slide table 200, a fixture 300 and a base 400.

[0022] The base 400 includes two interconnected parts, namely a base platform 401 and a turntable 402. The turntable 402 is rotatably connected to the base platform 401.

The output end of the first driver 404 is connected with a gear, and the gear meshes with the tooth part 403. After the first driver 404 is started, the gear drives the tooth part 403 to drive the turntable 402 to rotate, and the turntable 402 reciprocally rotates around the fixture 300 as the central position.

[0023] The sliding table 200 includes a first sliding seat 201, a second sliding seat 202, a third sliding seat 203 that are sequentially slidably connected, and related components. A guide rail, a screw rod, and a second motor 405 for driving the screw rod to rotate are provided on the turntable 402. The first sliding seat 201 is cooperatively connected with the guide rail and the screw rod and is slidably connected to the turntable 402 relatively. The sliding direction of the first sliding seat 201 is defined as the first direction. The top surface of the first sliding seat 201 is an inclined surface relative to the bottom surface. A guide rail, a screw rod, and a third driver 204 for driving the screw rod to rotate are connected to this inclined surface. The second sliding seat 202 is cooperatively connected with the guide rail and the screw rod and is slidably connected to the first sliding seat 201 relatively. The sliding direction of the second sliding seat 202 is defined as the second direction. The included angle between the first direction and the second direction is set as A, and 0° < A < 90°. A guide rail, a screw rod, and a fourth driver 205 for driving the screw rod to rotate are connected to the second sliding seat 202. The third sliding seat 203 is respectively cooperatively connected with the guide rail and the screw rod and is slidably connected to the second sliding seat 202 relatively. The sliding direction of the third sliding seat 203 is defined as the third direction. Among them, the first direction and the third direction are perpendicular to each other, and the second direction and the third direction are perpendicular to each other.

[0024] The sliding table 200 and the base 400 are defined as the load-bearing terminal 042, and there is at least one load-bearing terminal 042. In one embodiment, the load-bearing terminal 042 is one; in order to balance the cutting force, in a preferred embodiment, the load-bearing terminal 042 is two, and the two load-bearing terminals 042 are symmetrically distributed; in the remaining preferred embodiments, the number of load-bearing terminals 042 can be selected and set as needed. When there are two or more load-bearing terminals 042, they should be circumferentially arrayed with the position where the fixture 300 is located as the center.

[0025] The drilling terminal 100 is installed on the sliding table 200, specifically on the third sliding seat 203. In this embodiment, since the drilling process is to be completed, it is defined as the drilling terminal 100. According to the core idea of this solution, if other machining processes such as milling are to be completed, the drilling terminal 100 can be switched to other existing machining devices. The drilling terminal 100 includes a tool magazine 101 and a support seat 102. The tool magazine 101 is rotatably connected to the support seat 102, and tool positions 103 for fixing tools are arranged along the circumference of the tool magazine 101.
