Description

A boring device and boring tool Technical Field

[0001] This utility model relates to the field of boring machine technology, and in particular to a boring device and boring tool. Background Technology

[0002] A boring machine is a machine tool used to process high-precision holes. It can enlarge the hole diameter of the workpiece and improve the accuracy. It supports drilling, boring and rolling processes and is widely used in machinery manufacturing, automobile, aerospace and other fields.

[0003] Existing boring machines are used by mounting the boring bar on a tool holder, placing the workpiece on the worktable, using a motor inside the tool holder to drive the boring bar to rotate, and simultaneously using a drive motor inside the boring machine to drive the lead screw to rotate, which in turn moves the tool holder up and down with the help of a linear guide. The tool holder then brings the rotating boring bar to a position that is in contact with the workpiece surface or hole, and uses rotary cutting and continuous feeding to open or enlarge holes on the workpiece surface.

[0004] However, when the boring bar rotates and cuts the workpiece placed on the worktable, it will generate a certain axial thrust on the workpiece, causing the workpiece to be displaced after being subjected to force, resulting in workpiece position deviation and affecting the accuracy of workpiece hole opening or hole enlargement. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that when the boring tool rotates and cuts the workpiece placed on the worktable, it will generate a certain axial thrust on the workpiece, which will cause the workpiece to be displaced after being subjected to force, resulting in the workpiece position shift and affecting the accuracy of the workpiece opening or enlarging.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a boring device, comprising: a boring machine, which is placed on the ground to provide support for the overall component, wherein the boring machine drives the lead screw to rotate and pushes the tool holder to move up and down through a drive motor; a boring tool, which is set on the tool holder, wherein the tool holder drives the boring tool to rotate at high speed through an internal motor to cut the workpiece; a worktable, which is set on the boring machine for supporting and placing the workpiece; and a positioning device, which is set on the worktable for limiting the position of the workpiece placed on the worktable.

[0007] Preferably, the positioning device includes: a guide rail fixedly connected to the worktable, wherein a screw is fixedly connected to one side of the guide rail, and a threaded hole ring is threadedly connected to the surface of the screw; a first shaft bracket sleeved on the screw, wherein the first shaft bracket is rotatably mounted on the threaded hole ring by a retaining ring; and perforated plates, wherein two perforated plates are slidably mounted on the guide rail by second shaft brackets, wherein a push rod is rotatably connected between the second shaft bracket and the first shaft bracket.

[0008] The effect achieved by the above components is as follows: By setting up a positioning device, the workpiece is first placed on the worktable, so that the workpiece is positioned between two perforated plates. At this time, the screw ring is manually rotated, so that the screw ring moves away from the guide rail along the screw surface. During the movement, the screw ring pulls the first shaft to move, so that the first shaft pulls two second shafts to move in opposite directions along the inside of the guide rail through the push rod. The two second shafts drive the two perforated plates to move in opposite directions. When the two perforated plates move in opposite directions to the position of touching and pressing the workpiece surface, the workpiece is pressed and limited. This reduces the displacement of the workpiece after being subjected to the axial thrust of the boring tool, which could cause the workpiece to shift position and affect the accuracy of the workpiece opening or enlarging. This improves the stability of the workpiece during the boring process.

[0009] Preferably, the surface of the screw hole ring is fixedly connected with multiple auxiliary plates, and the multiple auxiliary plates are arranged at equal intervals.

[0010] The effect achieved by the above components is that by setting up an auxiliary plate, the operator's hand can be blocked, reducing the chance of slipping when manually rotating the screw hole ring.

[0011] Preferably, a positioning rod is fixedly connected to the inner wall of the guide rail, wherein the positioning rod is placed inside the two second shaft brackets to limit its movement.

[0012] The effect achieved by the above components is that by setting the positioning rod, the positioning rod can be placed inside the two second shaft frames to limit their movement, thereby reducing the tilting or shaking of the second shaft frames during movement.

[0013] Preferably, it further includes: an adjustment component, the adjustment component comprising: a perforated rod, the perforated rod being slidably mounted on the perforated plate, wherein one end of the perforated rod is fixedly connected to a pressure plate; and a pin, the surface of the pin being slidably connected to the inner wall of the perforated plate, wherein the perforated rod is placed inside the perforated plate and fixed by the pin being inserted into it, wherein the pin is made of magnetically attractive metal.

[0014] The effect achieved by the above components is as follows: By setting up a perforated rod and a pressure plate, when it is necessary to fix a workpiece with an uneven surface, the perforated rod is manually moved, causing it to move left and right along the inside of the perforated plate. This causes the pressure plate to move left and right. When the pressure plate moves to a position that matches the depth of the unevenness of the workpiece surface, the pin is manually inserted into the position inside the perforated plate and the perforated rod to fix the position of the perforated rod. Then, the pressure plate moves with the perforated plate to press and fix the workpiece. This achieves the adjustment of the pressing position of the perforated plate, reducing the situation where some workpieces have uneven surfaces, causing some parts of the workpiece to not be limited when the perforated plate presses the workpiece, resulting in workpiece shaking and affecting the stability of workpiece processing. This improves the clamping flexibility of the positioning device for the workpiece.

[0015] Preferably, a rubber pad is fixedly connected to the side of the pressure plate away from the perforated rod, wherein the surface of the rubber pad is provided with multiple protrusions.

[0016] The effect achieved by the above components is that by setting rubber pads, the fit between the pressure plate and the workpiece surface can be increased, while separating the two and reducing the wear on the workpiece surface when the pressure plate squeezes it.

[0017] Preferably, a magnetic strip is fixedly connected to the side of the perforated plate near the pin, wherein the magnetic strip is fixed to the pin by adsorption.

[0018] The effect achieved by the above components is that by setting up a magnetic strip, the magnetic strip can attract and fix the pin, reducing the possibility of the pin shaking and coming out of the multi-hole rod during use, which would affect the stability of the multi-hole rod.

[0019] Preferably, a boring tool is used in the boring device.

[0020] The beneficial effects of this utility model are:

[0021] By setting a positioning device, the workpiece placed on the worktable can be positioned, reducing the displacement of the workpiece after being subjected to the axial thrust of the boring tool, which could cause the workpiece to shift position and affect the accuracy of the workpiece's hole opening or reaming, thus improving the stability of the workpiece during the boring process.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Figure 1-4 shows a boring device, comprising: a boring machine 1, which is placed on the ground to provide support for the overall component, wherein the boring machine 1 drives the lead screw to rotate and pushes the tool holder 3 to move up and down through a drive motor; a boring bar 4, which is set on the tool holder 3, wherein the tool holder 3 drives the boring bar 4 to rotate at high speed through an internal motor to cut the workpiece; a worktable 2, which is set on the boring machine 1 and is used to support and place the workpiece; and a positioning device 5, which is set on the worktable 2 and is used to limit the workpiece placed on the worktable 2.

[0032] The positioning device 5 shown in Figures 2 and 3 includes: a guide rail 51, which is fixedly connected to the worktable 2, wherein a screw 52 is fixedly connected to one side of the guide rail 51, and a threaded ring 54 is threaded onto the surface of the screw 52; a first shaft bracket 53, which is sleeved on the screw 52, ​​and is rotatably mounted on the threaded ring 54 by a retaining ring; and perforated plates 59, wherein two perforated plates 59 are slidably mounted on the guide rail 51 by a second shaft bracket 58, wherein a push rod 56 is rotatably connected between the second shaft bracket 58 and the first shaft bracket 53. By setting the positioning device 5, the workpiece is first placed on the worktable 2, so that the workpiece is positioned between the two perforated plates 59. At this time, manual... Rotating the screw ring 54 causes it to move away from the guide rail 51 along the surface of the screw 52. During this movement, the screw ring 54 pulls the first shaft 53, which in turn pulls the two second shafts 58 along the inside of the guide rail 51 via the push rod 56. This causes the two second shafts 58 to move the two hole plates 59 in opposite directions. When the two hole plates 59 move in opposite directions to the position where they are in contact with and press against the workpiece surface, the workpiece is pressed and limited. This reduces the displacement of the workpiece after being subjected to the axial thrust of the boring tool 4, which could cause the workpiece to shift position and affect the accuracy of the hole opening or enlarging. This improves the stability of the workpiece during the boring process.

[0033] As shown in Figures 2 and 3, the surface of the screw hole ring 54 is fixedly connected with multiple auxiliary plates 55, which are arranged at equal intervals. By setting the auxiliary plates 55, the hands of personnel can be intercepted, reducing the possibility of slippage when manually rotating the screw hole ring 54. The inner wall of the guide rail 51 is fixedly connected with a positioning rod 57, which is placed inside the two second shaft brackets 58 to limit their movement. By setting the positioning rod 57, the positioning rod 57 can be placed inside the two second shaft brackets 58 to limit their movement, reducing the possibility of tilting or shaking of the second shaft brackets 58 during movement.

[0034] Figures 3 and 4 also show: an adjustment assembly 6, which includes: a perforated rod 61, slidably mounted on the perforated plate 59, with one end of the perforated rod 61 fixedly connected to a pressure plate 62; and a pin 63, the surface of which is slidably connected to the inner wall of the perforated plate 59. The perforated rod 61 is placed inside the perforated plate 59 and fixed by the pin 63 inserted inside it. The pin 63 is made of magnetically attractive metal. By setting up the perforated rod 61 and the pressure plate 62, when it is necessary to fix a workpiece with an uneven surface, the perforated rod 61 can be manually moved, causing it to move left and right along the inside of the perforated plate 59. The multi-hole rod 61 drives the pressure plate 62 to move left and right. When the pressure plate 62 moves to a position that matches the depth of the concave and convex surfaces of the workpiece, the pin 63 is manually inserted into the position of the perforated plate 59 and the multi-hole rod 61 to fix the position of the multi-hole rod 61. Then the pressure plate 62 moves with the perforated plate 59 to press and fix the workpiece, thereby achieving the adjustment of the pressing position of the perforated plate 59. This reduces the situation where some workpieces have concave and convex surfaces, causing some positions of the workpiece to be not limited when the perforated plate 59 presses the workpiece, resulting in workpiece shaking and affecting the stability of workpiece processing. This improves the clamping flexibility of the positioning device 5 for the workpiece.

[0035] As shown in Figures 3 and 4, a rubber pad 65 is fixedly connected to the side of the pressure plate 62 away from the perforated rod 61. The surface of the rubber pad 65 has multiple protrusions. By setting the rubber pad 65, the fit between the pressure plate 62 and the workpiece surface can be increased, and the two can be separated to reduce the wear caused to the workpiece surface when the pressure plate 62 is pressing on it. A magnetic strip 64 is fixedly connected to the side of the perforated plate 59 near the pin 63. The magnetic strip 64 fixes the pin 63 by adsorbing it. By setting the magnetic strip 64, the pin 63 can be adsorbed and fixed, reducing the possibility that the pin 63 will shake and fall out of the perforated rod 61 during use, which would affect the stability of the perforated rod 61.

[0036] Working principle: First, manually move the perforated rod 61, causing it to move left and right along the inside of the perforated plate 59. This causes the pressure plate 62 to move left and right. When the pressure plate 62 moves to a position that matches the depth of the workpiece surface, manually insert the pin 63 into the perforated plate 59 and the perforated rod 61 to fix the position of the perforated rod 61, thus adjusting the pressing position of the perforated plate 59. At this point, place the workpiece on the worktable 2, positioning it between the two perforated plates 59. Then, manually rotate the screw hole. Ring 54 causes the screw hole ring 54 to move away from the guide rail 51 along the surface of the screw 52. During the movement, the screw hole ring 54 pulls the first shaft bracket 53 to move. The first shaft bracket 53 pulls the two second shaft brackets 58 to move in opposite directions along the inside of the guide rail 51 through the push rod 56. The two second shaft brackets 58 drive the two perforated plates 59 to move in opposite directions. The two perforated plates 59 drive the pressure plate 62 to move. When the pressure plate 62 moves in opposite directions to the position of adhering to and pressing the workpiece surface, the pressing and limiting of the workpiece is completed.

[0037] The boring machine 1 in this application is a T7220A vertical precision boring machine. During processing, the boring tool 4 is mounted on the tool holder 3. The motor inside the tool holder 3 drives the boring tool 4 to rotate at high speed. At the same time, the drive motor inside the boring machine 1 drives the lead screw to rotate, and the linear guide rail 51 drives the tool holder 3 to move up and down. Then the tool holder 3 brings the rotating boring tool 4 to the position where it fits against the surface or hole of the workpiece. By using rotary cutting and continuous feeding, holes are opened or enlarged on the surface of the workpiece.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
