Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, specifically a material support mechanism for a milling machine used for hardware processing. Background Technology

[0002] A milling machine is a metal cutting machine tool that performs cutting operations on a workpiece through the rotational motion of a milling cutter and the feed motion of the workpiece. The spindle of the milling machine drives the milling cutter to rotate, while the workpiece is fixed on the worktable. The milling cutter cuts the workpiece through the feed motion of the worktable. During the cutting process, the rotational motion of the milling cutter is the main motion, and the feed motion of the workpiece is the feed motion. Milling machines are widely used in many industries, such as processing various mechanical parts and hardware components.

[0003] In the current technology, during the milling process of hardware parts, the worktable that supports and fixes the hardware parts needs to move back and forth in three directions as required. However, the fixed table is an integral structure. When the hardware parts to be processed have special shapes, the parts may be suspended in mid-air. In this case, the clamping and fixing function of the worktable on the parts cannot be guaranteed, and displacement may occur during the subsequent milling process, which will affect the milling quality of the workpiece by the device.

[0004] Therefore, a material support mechanism for a milling machine used for machining hardware parts is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problem that when the fixed table is an integral structure, the parts to be processed may be suspended in mid-air, which makes it impossible to guarantee the clamping and fixing effect of the worktable on the parts. Furthermore, displacement may occur during the subsequent milling process, affecting the milling quality of the workpiece. Therefore, a material support mechanism for a metal parts milling machine is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The material support mechanism of a milling machine for processing hardware parts according to this utility model includes a worktable body. A slider groove is provided on the side wall of the worktable body. A displacement slider is slidably installed between the inner walls of the slider groove. A threaded through hole is provided at the center of the side wall of the displacement slider. A lead screw is installed in the threaded through hole. The two ends of the lead screw are fixed to the inner walls of the two ends of the slider groove by bearings. A top plate lifting frame is fixed to the side wall of the displacement slider. A rotating lifting seat is hinged inside the top plate lifting frame. A supporting base plate is fixed to the top surface of the rotating lifting seat. The top surface of the supporting base plate is coplanar with the top surface of the worktable body.

[0007] Preferably, the top surface of the supporting base plate is provided with a top rod groove, and a top rod slider is slidably installed between the inner walls of the top rod groove.

[0008] Preferably, the top surface of the push rod slider is provided with a push rod slot.

[0009] Preferably, a polygonal prism is fixedly connected to the bottom center of the rotating hoisting base, a limiting circular plate is fixedly connected to one end of the polygonal prism, and an annular circular plate is fitted on the outer wall of the polygonal prism, with the inner hole of the annular circular plate sliding in contact with the outer wall of the polygonal prism.

[0010] Preferably, a return spring is fitted on the outer wall of the polygonal prism, and the return spring is located between the adjacent side walls of the limiting circular plate and the annular circular plate.

[0011] Preferably, the top surface of the annular plate has multiple limiting openings, which are equally spaced along half the circumference of the top surface of the limiting plate, and a pressing handle is fixedly connected to the outer wall of the annular plate.

[0012] Preferably, the bottom surface of the rotating hoisting base is fixedly connected to a positioning protrusion, which can engage with the inner wall of one of the limiting openings.

[0013] Preferably, a motor is installed on one side wall of the main body of the worktable, and the output shaft of the motor passes through the interior of the slider groove and is connected to the axis of the lead screw.

[0014] The beneficial effects of this utility model are:

[0015] In this invention, the metal parts to be processed are clamped and fixed by the cooperation between the clamping block groove and the fixed clamping block on the main body of the worktable. When the shape of the metal parts is so special that part of the body is suspended, the supporting base plate can cooperate with the push rod slider to provide auxiliary support for the suspended part. When the suspended part is not coplanar with the top surface of the main body of the worktable and the supporting base plate, a push rod of appropriate length is selected and installed in the push rod slot, with one end of it contacting the bottom of the workpiece to be processed, ensuring the stable support of the main body of the worktable. The rotating hoist seat hinged in the displacement slider can move with the displacement slider and change its position relative to the part by rotating, adapting to the changes in the shape of the part to be processed, ensuring the stable support of the device, and thus ensuring the milling quality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figure 1 - Figure 4This utility model provides a material support mechanism for a milling machine for machining hardware parts, including a worktable body 1. A slider groove 11 is formed on the side wall of the worktable body 1. A displacement slider 2 is slidably installed between the inner walls of the slider groove 11. A threaded through hole 21 is formed at the center of the side wall of the displacement slider 2. A lead screw 3 is threaded into the threaded through hole 21. The two ends of the lead screw 3 are fixed to the inner walls of the two ends of the slider groove 11 by bearings. A top plate lifting frame 22 is fixed to the side wall of the displacement slider 2. A rotating lifting seat 4 is hinged inside the top plate lifting frame 22. A supporting base plate 41 is fixed to the top surface of the rotating lifting seat 4. The top surface of the supporting base plate 41 is coplanar with the top surface of the worktable body 1. After the part to be milled is placed on the top surface of the worktable body 1, it is supported by the interlocking of the clamping plate and the strip groove on its top surface. The parts are clamped and fixed, while the displacement slider 2 is installed on the main body 1 of the worktable through the slider groove 11. The lead screw 3 in the slider groove 11 is threadedly engaged with the threaded through hole 21, which allows the relative position of the displacement slider 2 to change during the rotation of the lead screw 3. The displacement slider 2 is installed on the support plate 41 through the rotating hoisting seat 4 hinged in the top plate hoisting frame 22. This allows the support plate 41, which provides auxiliary support for the parts, to rotate with the rotating hoisting seat 4 around the rotation axis of the top plate hoisting frame 22, and also to move with the displacement slider 2. This allows the support position of the support plate 41 to adapt to the specific shape of the parts, ensuring the auxiliary support function of the device for the workpiece, and thus ensuring the milling accuracy to a certain extent.

[0026] like Figure 2 and Figure 4 As shown, a push rod groove 42 is provided on the top surface of the supporting base plate 41. A push rod slider 5 is slidably installed between the inner walls of the push rod groove 42. A push rod slot 51 is provided on the top surface of the push rod slider 5. When the part is not coplanar with the top surface of the workbench body 1 and the supporting base plate 41, the push rod slider 5 in the push rod groove 42 is moved to a suitable position, and a push rod of appropriate length is selected and installed in the push rod slot 51, with one end of it contacting the bottom of the workpiece to be processed, so as to ensure the stable support of the workbench body 1.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, a polygonal prism 23 is fixedly connected to the center of the bottom of the rotating hoisting base 4. A limiting circular plate 24 is fixedly connected to one end of the polygonal prism 23. An annular circular plate 6 is fitted onto the outer wall of the polygonal prism 23. The inner hole of the annular circular plate 6 slides against the outer wall of the polygonal prism 23. A return spring is fitted onto the outer wall of the polygonal prism 23. The return spring is located between the adjacent side walls of the limiting circular plate 24 and the annular circular plate 6. Multiple limiting openings 61 are opened on the top surface of the annular circular plate 6. The multiple limiting openings 61 are equally spaced along the half-circumference of the top surface of the limiting circular plate 24. A pressing handle 62 is fixedly connected to the outer wall of the annular circular plate 6. A positioning protrusion 43 is fixedly connected to the bottom surface of the rotating hoisting base 4. The positioning protrusion 43 can engage with the inner wall of one of the limiting openings 61. The annular plate 6 on the outer wall of the prism 23 can slide back and forth within its outer wall range. When the downward pressure is applied to the downward handle 62, the annular plate 6 moves down as a whole until the positioning protrusion 43 and the limiting opening 61 disengage from each other. At this time, the annular plate 6 loses its function of limiting the rotation of the rotating lifting seat 4. At this time, the rotating lifting seat 4 and the supporting base plate 41 are rotated as a whole to the required angle. After the supporting base plate 41 moves to below the part that is vacated, the downward pressure is released. At this time, the return spring 7 installed between the annular plate 6 and the limiting plate 24 provides an elastic force for the annular plate 6 to move upward. The limiting openings 61 of the positioning protrusion 43 at different positions engage with each other, limiting the position of the rotating lifting seat 4 and the supporting base plate 41 as a whole.

[0028] like Figure 1 and Figure 2 As shown, a motor 8 is installed on one side wall of the main body 1 of the workbench. The output shaft of the motor 8 passes through the inside of the slider groove 11 and is connected to the axis of the lead screw 3. The motor 8 provides output force for the rotation of the lead screw 3, thereby controlling the displacement slider 2 and the overall displacement of the rotating hoisting seat 4 in the lateral direction.

[0029] Working Principle: After the part to be milled is placed on the top surface of the worktable body 1, it is clamped and fixed by the interlocking of the clamping plate and the top surface groove. The displacement slider 2 is installed on the worktable body 1 through the slider groove 11. The lead screw 3 in the slider groove 11 is threaded into the threaded through hole 21, allowing the relative position of the displacement slider 2 to change during the rotation of the lead screw 3. The motor 8 provides output force for the rotation of the lead screw 3, thereby controlling the lateral displacement of the displacement slider 2 and the rotating lifting seat 4. The displacement slider 2 is installed on the support base 41 through the rotating lifting seat 4 hinged in the top plate lifting frame 22. This allows the support base 41, which provides auxiliary support for the part, to rotate with the rotating lifting seat 4 around the axis of the top plate lifting frame 22, and also to move with the displacement slider 2. This allows the support position of the support base 41 to adapt to the specific shape of the part. When the part is suspended in the air, it is not in contact with the top surface of the worktable body 1. When the workpiece is coplanar, move the push rod slider 5 in the push rod groove 42 to a suitable position, select a push rod of appropriate length and clamp it in the push rod slot 51, and make one end of it contact the bottom of the workpiece to be processed, so as to ensure the stable support of the worktable body 1. The annular plate 6 fitted on the outer wall of the polygonal prism 23 can slide back and forth within its outer wall range. When the downward pressure is applied to the downward handle 62, the annular plate 6 moves down as a whole until the positioning protrusion 43 and the limiting opening 61 are disengaged. At this time, the annular plate 6 loses its rotation limiting function for the rotating hoisting seat 4. At this time, control the rotating hoisting seat 4 and the supporting base plate 41 to rotate as a whole to the required angle, and after the supporting base plate 41 moves to below the part that is vacated, release the downward pressure. At this time, the return spring 7 installed between the annular plate 6 and the limiting plate 24 provides the annular plate 6 with an upward elastic force. The limiting openings 61 of the positioning protrusion 43 at different positions engage with each other, limiting the position of the rotating hoisting seat 4 and the supporting base plate 41 as a whole.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
