Description

Technical Field

[0001] This utility model belongs to the field of horizontal drilling machine technology, specifically relating to a horizontal drilling machine with tapping function. Background Technology

[0002] A drilling machine is a machine tool that primarily uses a drill bit to machine holes in a workpiece. Drilling machines have a simple structure and relatively low machining accuracy. They can drill through holes and blind holes. By changing special cutting tools, they can also perform reaming, countersinking, boring, or tapping. For parts that require tapping, the process usually involves first drilling a hole with a drill bit, and then using a tap to tap the hole.

[0003] However, in the drilling and tapping process of ordinary horizontal drilling machines, multiple tool changes and positioning are required. Furthermore, when the drilling machine is used for drilling and tapping in different positions, it leads to high workload and low efficiency. The multiple positioning also results in low precision and easily scratched products. In addition, because the spindle box of the drilling machine cannot be changed at will, speed changes require altering the belt pulleys, which is time-consuming, labor-intensive, and has a limited speed range. The tapping feed speed must be compatible with the tapping pitch; otherwise, the tap will break. Therefore, when tapping heads are used with the drilling machine spindle box, they usually require a high level of operator experience. Tapping feed is mainly done manually, which is difficult under high precision requirements, increasing the labor intensity of workers and reducing work efficiency. Utility Model Content

[0022] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0023] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," "right," "front," "rear," "top," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. It should also be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0024] like Figures 1 to 5 As shown, a preferred embodiment of this utility model provides a horizontal deep hole drilling machine, which includes a base 1, a column 2, a worktable 3, a drilling mechanism 4, a tapping mechanism 5, a spindle mounting base 6, a first X-axis moving mechanism 7, a second X-axis moving mechanism 8, a Y-axis moving mechanism 9, and a Z-axis moving mechanism 10; the column 2 is fixed to the rear side of the base 1, the worktable 3 is connected to the front side of the base 1 through the Y-axis moving mechanism 9, and the worktable 3 is driven by the Y-axis moving mechanism 9 to move left and right along the Y-axis direction; the spindle mounting base 6 is connected to the column 2 through the Z-axis moving mechanism 10, and the drilling mechanism 4 is driven by the Z-axis moving mechanism 10 to move up and down along the Z-axis direction; the drilling mechanism 4 is connected to the column 2 through the Z-axis moving mechanism 10. The drilling mechanism 4 is connected to the spindle mounting base 6 via the first X-axis moving mechanism 7. The drilling mechanism 4 is driven by the first X-axis moving mechanism 7 to move back and forth along the X-axis direction. The drilling mechanism 4 is horizontally arranged and is provided with a drill head 41. The drill head 41 extends along the X-axis direction and faces the worktable 3. The tapping mechanism 5 is connected to the side of the drilling mechanism 4 via the second X-axis moving mechanism 8. The tapping mechanism 5 is driven by the second X-axis moving mechanism 8 to move back and forth along the X-axis direction. The tapping mechanism 5 is provided with a tapping head 51. The tapping head 51 extends along the X-axis direction and faces the worktable 3. The drill head 41 and the tapping head 51 are located at the same horizontal height.

[0025] During operation, the drilling mechanism 4 moves to the drilling position under the drive of the first X-axis moving mechanism 7, the Y-axis moving mechanism 9, and the Z-axis moving mechanism 10 to realize the drilling operation. After drilling is completed, since the tapping mechanism 5 is connected to the side of the drilling mechanism 4 through the second X-axis moving mechanism 8, the center distance between the drilling head 41 and the tapping head 51 remains unchanged, and the drilling head 41 and the tapping head 51 are at the same horizontal height. Therefore, the drilling mechanism 4 only needs to move out of the drilling position in the Y-axis direction through the Y-axis moving mechanism 9, and at the same time, the tapping mechanism 5 also moves to the drilling position under the drive of the Y-axis moving mechanism 9, thereby realizing quick tool change and positioning. Therefore, this utility model embodiment adopts a horizontal drilling machine structure, combining the advantages of drilling machines and tapping machines, and combining two working heads with different processing functions, drilling head 41 and tapping head 51, to achieve multi-functional processing of drilling and tapping, greatly improving the applicability of the machine tool, and making it suitable for drilling and tapping in different positions. This effectively solves the problem of multiple tool changes and multiple positioning in the process of drilling and tapping on a horizontal drilling machine, improving work efficiency and processing accuracy. In addition, this horizontal drilling machine replaces multiple machines with one machine, saving production costs and reducing the space required in the processing workshop.

[0026] For example, the drilling mechanism 4 includes a spindle box 42, a spindle motor 43, and a belt drive assembly 44. The spindle box 42 is connected to the spindle mounting base 6 via the first X-axis moving mechanism 7. The spindle motor 43 is mounted above the spindle box 42 via a motor bracket 45. The power output end of the spindle motor 43 is connected to the spindle disposed in the spindle box 42 via the belt drive assembly 44. The spindle in the spindle box 42 is connected to the drill head 41 via a clamp. Thus, the spindle box 42 is the component in the drilling mechanism 4 used to house the spindle, not only supporting the spindle but also containing a mechanism for adjusting the spindle speed and direction. The spindle motor 43 is the power source of the drilling mechanism 4, driving the drill head 41 to work through rotational force. The belt drive assembly 44 is a mechanical transmission component connecting the spindle motor 43 and the spindle, transmitting the rotational motion of the spindle motor 43 to the spindle via a belt. In addition, the belt drive can provide a flexible connection, reducing vibration and impact, while allowing adjustment of different speeds.

[0027] For example, the tapping mechanism 5 includes a reduction gearbox 52 and a tapping motor 53. The reduction gearbox 52 is connected to the side of the spindle box 42 via the second X-axis moving mechanism 8. The tapping motor 53 is mounted on the reduction gearbox 52. The power output end of the spindle motor 43 is connected to the input end of the reduction gearbox 52, and the output end of the reduction gearbox 52 is connected to the tapping head 51 via a clamp. Thus, the tapping motor 53 is the power source of the tapping mechanism 5, driving the tapping head 51 to work through rotational force. The function of the reduction gearbox 52 is to reduce the high-speed rotation of the tapping motor 53 to a lower speed suitable for tapping, while increasing torque to ensure the efficiency and accuracy of the tapping process.

[0028] For example, the first X-axis moving mechanism 7 includes a first X-axis slide 71, a first X-axis rolling linear guide pair 72, a first X-axis ball screw nut pair 73, and an X-axis servo motor 74. The first X-axis rolling linear guide pair 72 and the first X-axis ball screw nut pair 73 are both arranged along the X-axis direction. The first X-axis slide 71 is slidably mounted on the spindle mounting base 6 via the first X-axis rolling linear guide pair 72. The X-axis servo motor 74 is fixed on the spindle mounting base 6. The power output end of the X-axis servo motor 74 is connected to the lead screw of the first X-axis ball screw nut pair 73. The nut of the first X-axis ball screw nut pair 73 is connected to the first X-axis slide 71. The spindle box 42 is mounted on the first X-axis slide 71. Therefore, the X-axis servo motor 74 is the power source of the first X-axis moving mechanism 7. The rotation of the X-axis servo motor 74 drives the first X-axis ball screw nut pair 73 to change from rotational motion to linear motion, so that the first X-axis slide 71 moves back and forth along the X-axis direction under the guidance of the first X-axis rolling linear guide pair 72, thereby realizing the X-axis stroke control of the drilling mechanism 4.

[0029] For example, the second X-axis moving mechanism 8 includes a second X-axis slide 81, a second X-axis rolling linear guide pair 82, and an X-axis drive cylinder 83. The second X-axis rolling linear guide pair 82 is arranged along the X-axis direction. The second X-axis slide 81 is slidably mounted on the side of the spindle box 42 via the second X-axis rolling linear guide pair 82. The X-axis drive cylinder 83 is fixed to the side of the drilling mechanism 4. The piston rod of the X-axis drive cylinder 83 is connected to the second X-axis slide 81. The reduction gearbox 52 is mounted on the second X-axis slide 81. Thus, the X-axis drive cylinder 83 is the power source of the second X-axis moving mechanism 8. The X-axis drive cylinder 83 pushes the second X-axis slide 81 to move back and forth along the X-axis direction under the guidance of the first X-axis rolling linear guide pair 82, thereby realizing the X-axis stroke control of the tapping mechanism 5.

[0030] For example, the Y-axis moving mechanism 9 includes a Y-axis rolling linear guide pair 91, a Y-axis ball screw nut pair 92, and a Y-axis servo motor 93. Both the Y-axis rolling linear guide pair 91 and the Y-axis ball screw nut pair 92 are arranged along the Y-axis direction. The worktable 3 is slidably mounted on the base 1 via the Y-axis rolling linear guide pair 91. The Y-axis servo motor 93 is fixed to the base 1. The power output end of the Y-axis servo motor 93 is connected to the lead screw of the Y-axis ball screw nut pair 92, and the nut of the Y-axis ball screw nut pair 92 is connected to the worktable 3. Thus, the Y-axis servo motor 93 is the power source of the Y-axis moving mechanism 9. The rotation of the Y-axis servo motor 93 drives the Y-axis ball screw nut pair 92 from rotational motion to linear motion, causing the worktable 3 to move left and right along the Y-axis direction under the guidance of the Y-axis rolling linear guide pair 91, thereby achieving Y-axis stroke control of the worktable 3.

[0031] For example, the Z-axis moving mechanism 10 includes a Z-axis rolling linear guide pair 101, a Z-axis ball screw nut pair 102, and a Z-axis servo motor 103. The Z-axis rolling linear guide pair 101 and the Z-axis ball screw nut pair 102 are both arranged along the Z-axis direction. The spindle mounting seat 6 is slidably mounted on the column 2 through the Z-axis rolling linear guide pair 101. The Z-axis servo motor 103 is fixed on the column 2. The power output end of the Z-axis servo motor 103 is connected to the screw of the Z-axis ball screw nut pair 102. The nut of the Z-axis ball screw nut pair 102 is connected to the spindle mounting seat 6. Therefore, the Z-axis servo motor 103 is the power source of the Z-axis moving mechanism 10. The rotation of the Z-axis servo motor 103 drives the Z-axis ball screw nut pair 102 to change from rotational motion to linear motion, so that the worktable 3 moves up and down along the Z-axis under the guidance of the Z-axis rolling linear guide pair 101, thereby realizing the Z-axis stroke control of the spindle mounting seat 6.

[0032] 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
