Description

Technical Field

[0001] The utility model relates to the technical field of cleaning components of numerical control machine tools, in particular to a workpiece mounting platform for a numerical control machining center. Background Art

[0002] Machining centers evolved from CNC milling machines. Their biggest difference is their ability to automatically change machining tools. By installing tools for different purposes in the tool magazine, the automatic tool changer can change the machining tool on the spindle during a single setup, enabling multiple machining functions.

[0003] CNC machining centers are highly efficient automated machines composed of mechanical equipment and CNC systems suitable for machining complex parts. They are among the world's most productive and widely used CNC machine tools. They offer strong comprehensive machining capabilities, enabling them to complete a wide range of machining tasks with a single workpiece clamping, while maintaining high precision. For batch machining of moderately difficult workpieces, their efficiency is 5 to 10 times that of conventional equipment. They can perform many tasks that conventional equipment cannot, making them particularly suitable for single-piece machining with complex shapes and high precision requirements, or for small to medium-volume, high-variety production. They integrate milling, boring, drilling, tapping, and thread cutting functions into a single machine, enabling them to handle a wide range of machining processes and techniques. Machining centers can be categorized by the spatial position of the spindle during machining: horizontal and vertical. They can be categorized by their application: boring and milling centers, and multi-tasking centers. They can be categorized by their specific functions: single-, double-, and multi-table machining centers. Machining centers with single, double, and triple axes, as well as those with interchangeable spindle boxes, are also available. They can be categorized by their guide rails: linear guide rail machining centers and hard guide rail machining centers.

[0004] Most existing workpiece mounting tables are grooved at the top and use a sliding method to fix the fixture. However, during the processing, a lot of cutting fluid and iron chips will be left in the grooves of the guide rails, and an air gun is needed for cleaning in the later cleaning. However, the cutting fluid remaining in the mounting groove is difficult to be cleaned, and it is easy to cause the mounting table to rust over time. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings in the prior art and to propose a workpiece mounting platform for a CNC machining center.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A workpiece mounting platform for a numerical control machining center includes a workpiece mounting platform body, wherein the workpiece mounting platform body is in the form of a rectangular parallelepiped and has a mounting groove formed in a horizontal direction thereof, and the mounting groove is arranged in an inverted trapezoidal shape;

[0008] Openings are provided on both sides of the top of the mounting groove, a filter screen is provided on the top of the opening, and a connecting pipe is connected to the bottom of the opening. The connecting pipe is "L" shaped and is connected to a transition pipe provided inside the workpiece mounting platform body.

[0009] In addition, a preferred structure is that the openings on the mounting groove become deeper and deeper in the horizontal direction, and the opening between every two openings decreases by 1 mm.

[0010] In addition, a preferred structure is that the end of the transition pipe connected to the end of each open bottom connecting pipe is connected to a collecting pipe, and the flow direction in the collecting pipe is horizontal.

[0011] In addition, a preferred structure is that the end of the collecting pipe is connected to a drain pipe, and the drain pipe is arranged vertically downward.

[0012] In addition, a preferred structure is that a drain port is provided at the bottom of the workpiece mounting platform body, and the drain port and the drain pipe are adapted to each other.

[0013] In addition, a preferred structure is that the collecting pipe connected to the end of the transition pipe is inclined, and its inclination angle is 10°.

[0014] The beneficial effects of the utility model are as follows: first, openings are opened on both sides of the top of the mounting groove opened on the workpiece mounting table body, and a filter screen is set at the top of the opening, and a connecting pipe is connected to the bottom of the opening, and the cutting fluid is discharged into the collecting pipe through the connecting pipe, and the inclined state of the collecting pipe is utilized to enable the cutting fluid to be discharged more quickly, thereby avoiding the accumulation of cutting fluid in the mounting groove.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4 A workpiece mounting platform for a CNC machining center includes a workpiece mounting platform body 1, which is a rectangular parallelepiped and has a mounting groove 2 in a horizontal direction, and the mounting groove 2 is arranged in an inverted trapezoidal shape;

[0022] Openings 32 are provided on both sides of the top of the mounting groove 2, a filter screen 3 is provided on the top of the opening 32, and a connecting pipe 31 is connected to the bottom of the opening 32. The connecting pipe 31 is "L"-shaped and is connected to the transition pipe 5 provided inside the workpiece mounting platform body 1.

[0023] The openings 32 on the mounting groove 2 become deeper and deeper in the horizontal direction, and the openings 32 between every two openings 32 decrease by 1 mm.

[0024] In addition, the end of the transition pipe 5 connected to the end of the connecting pipe 31 at the bottom of each opening 32 is connected to a collecting pipe 6, and the flow direction in the collecting pipe 6 is horizontal.

[0025] In addition, the end of the collecting pipe 6 is connected to a drain pipe 7, and the drain pipe 7 is arranged vertically downward.

[0026] At the same time, a drain port 4 is provided at the bottom of the workpiece mounting platform body 1 , and the drain port 4 and the drain pipe 7 are adapted to each other.

[0027] Moreover, the collecting pipe 6 connected to the end of the transition pipe 5 is inclined, and its inclination angle is 10°.

[0028] In this embodiment, the fixture is first installed and positioned through the mounting groove 2, and then during the processing in the CNC machining center, a large amount of iron chips and cutting fluid will be generated. These iron chips and cutting fluid will be discharged through the mounting groove 2 opened on the workpiece mounting table body 1.

[0029] However, in the later cleaning process using an air gun, the cutting fluid remaining in the mounting groove 2 is first blown away, and then when the cutting fluid reaches the openings 32 opened on both sides of the mounting groove 2, since the filter screen 3 is set at the top of the opening 32, only liquids such as cutting fluid fall from the opening 32 and flow into the connecting pipe 31, and then the connecting pipe 31 discharges the liquid into the transition pipe 5, and uses the pressure in the pipeline to discharge the cutting fluid to the collecting pipe 6, and since the collecting pipe 6 is inclined, the cutting fluid will be discharged from the collecting pipe 6 and reach the drain pipe 7 at the bottom from the collecting pipe 6.

[0030] Then when the cutting fluid reaches the drain pipe 7 at the bottom, it is discharged through the drain port 4 opened at the bottom of the workpiece mounting table body 1. This not only allows the cutting fluid and iron chips to be discharged separately, but also allows the cutting fluid to flow out more quickly.

[0031] In the present invention, openings 32 are firstly opened on both sides of the top of the mounting groove 2 opened on the workpiece mounting table body 1, and a filter screen 3 is provided at the top of the opening 32, and a connecting pipe 31 is connected to the bottom of the opening 32, and the cutting fluid is discharged into the collecting pipe 6 through the connecting pipe 31, and the inclined state of the collecting pipe 6 is utilized to enable the cutting fluid to be discharged more quickly, thereby avoiding the accumulation of cutting fluid in the mounting groove 2.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
