Referring to fig. 1-3, the drilling mechanism provided by the present invention includes a two-axis moving device 1 disposed on the top of a machine a of a cam-type lathe, and a drill driving device 2 disposed on the two-axis moving device; the two-axis moving device 1 is used for driving the drill driving device 2 to move along the longitudinal direction and the transverse direction (herein, the longitudinal direction refers to the direction parallel to the workpiece, the transverse direction refers to the direction horizontally vertical to the longitudinal direction, and the vertical direction refers to the vertical direction); the drill bit driving device 2 comprises a plurality of drill bit mounting seats 2.1 which are arranged in the transverse direction, and each drill bit mounting seat is connected with one linear driving device 2.2 and driven by the linear driving device to move along the axial direction of the workpiece; each drill bit mounting seat 2.1 can move to the axis of the workpiece under the driving of the two-axis moving device (as the two-axis moving device can drive the drill bit mounting seats 2.1 to move along the transverse direction, as long as the height of the drill bit mounting seats 2.1 is flush with the workpiece, each drill bit mounting seat 2.1 can be guaranteed to move to the axis of the workpiece under the driving of the two-axis moving device).
When the drilling machine works, the drill bits with different sizes are arranged in the drill bit installation seats 2.1, a workpiece is driven to rotate by a main shaft C of the cam type lathe, the position of the workpiece is adjusted by the two-shaft moving device 2 to enable the required drill bit to be aligned with the workpiece, and then the drill bit installation seats 2.1 are pushed forward to drill holes by the linear driving device 2.2 corresponding to the drill bits; the multi-section holes with different diameters can be machined by switching the drill bit which is opposite to the workpiece; the small holes are drilled by the drill bits with smaller sizes, and then the drill bits are sequentially switched to the drill bits with larger sizes for hole expansion, so that the high-precision machining of the holes can be realized.
In the present embodiment, as shown in fig. 3, each drill mounting seat 2.1 includes a mounting seat main body 2.1a, a position adjusting block 2.1b disposed at the front of the mounting seat main body, and a drill clamp 2.1c inserted on the position adjusting block; the position adjusting block 2.1b is used for adjusting the vertical position of the drill bit clamp 2.1 c. If the drill bit clamp 2.1c is directly fixed on the mounting seat main body 2.1a, due to assembly errors, the drill bit and a workpiece are difficult to ensure to be strictly centered, the vertical position of the drill bit clamp 2.1c can be adjusted through the adjusting block 2.1b, the transverse position of the drill bit clamp 2.1c is adjusted through the two-axis moving device 1, the position of the drill bit clamp can be adjusted to be optimal according to the actual situation, and the position accuracy of drilling is improved.
Further, as shown in fig. 3, a vertical dovetail groove 2.1b1 is formed in the position adjusting block 2.1b, a corresponding guide portion 2.1a1 is arranged at the front of the mounting seat main body 2.1a, and the dovetail groove 2.1b1 is slidably sleeved on the guide portion 2.1a1 and locked by a locking screw 2.1 c.
In some embodiments, a washer 2.1d is provided between the locking screw 2.1c and the guide 2.1a 1. The washer 2.1d can prevent the locking screw from scratching the guide part 2.1a1 to cause locking failure.
In addition, the drill bit clamp 2.1c is slidably arranged on the adjusting block 2.1b in a penetrating way and is locked by a plurality of locking screws so as to be convenient to assemble, disassemble and replace. The upper end of the dovetail groove 2.1b1 is provided with a connecting block 2.1e, the connecting block 2.1e is fixedly connected with the adjusting block 2.1b and is in screw connection with the mounting seat main body 2.1a, and the vertical force is borne by the screw, so that the shearing action force between the locking screw 2.1c and the guide part 2.1a1 is reduced.
Furthermore, each drill bit mounting seat 2.1 is correspondingly provided with a linear rail 2.3 consisting of a sliding rail 2.3a and a sliding block 2.3b, the sliding rail 2.3a is parallel to the axis of the workpiece, and the sliding block 2.3b is fixedly connected with the drill bit mounting seat 2.1.
The linear rail 2.3 here means that the rolling guide may be a linear ball guide (with balls on the slider), a linear roller guide (with rollers on the slider), a needle roller guide (with needles on the slider), etc., and rolling friction is present between the slide rail 2.3a and the slider 2.3b, which results in a lower friction force, and the linear rail 2.3 is an existing product, which can be purchased directly from the market, and compared with a method of directly processing a slide rail on the biaxial movement device 1, the processing precision is higher, the sliding is smoother, and the maintenance rate is lower.
Specifically, the linear driving device 2.2 may adopt an air cylinder, a hydraulic cylinder, an electric telescopic rod, and the like, and an air cylinder is adopted in fig. 3.
Preferably, all linear drives 2.2 can be mounted in a protective housing 2.4, as shown in fig. 2. The protective shell can prevent sand dust or metal debris from entering, keep the linear driving device 2.2 clean and reduce maintenance frequency.
In this embodiment, as shown in fig. 1, the two-axis moving device 1 includes a longitudinal linear rail 1.1, a longitudinal sliding base 1.2 disposed on the longitudinal linear rail, a longitudinal screw transmission pair 1.3 and a longitudinal servo motor 1.4 for driving the longitudinal sliding base to move, a transverse linear rail 1.5 disposed on the longitudinal sliding base 1.2, a transverse sliding base 1.6 disposed on the transverse linear rail, and a transverse screw transmission pair 1.7 and a transverse servo motor 1.8 for driving the transverse sliding base to move; the drill drive 2 is arranged on a transverse carriage 1.6. Through the cooperation of the screw rod transmission pair and the linear rail, the precision of displacement control is high, and therefore the machining precision can be improved.
Referring to fig. 4, the present invention further provides a cam-type lathe, which includes a machine table a, a tool rest mechanism B disposed on the top of the machine table, a spindle C disposed on one side of the tool rest mechanism, and a drilling mechanism D disposed on the other side of the tool rest mechanism; the drilling mechanism D is the drilling mechanism described above. When machining is performed, a tool is driven to rotate by the spindle C, the tool rest mechanism B performs cutting on the outside of the spindle C, and the drilling mechanism D performs drilling on the tool.
Here, the spindle C is provided on a moving stage C2 driven by a lead screw and servo motor C1, and the moving stage C2 is movable in the axial direction of the workpiece, so that the workpiece is moved in the axial direction by the spindle C to perform machining at different positions.
In this embodiment, the tool rest mechanism B includes a frame plate B1 fixedly connected to the machine table a, a plurality of radially arranged cutting tools B2 for the workpiece, and a plurality of cam driving assemblies B3 arranged on the frame plate; the cutting tools B2 are in one-to-one correspondence with the cam drive assemblies B3, and each cutting tool is driven by one cam drive assembly to move along the radial direction of the workpiece.
A typical cam lathe is generally provided with less cam driving assemblies than cutting tools (e.g., 5 cutting tools are driven by 3 cam driving assemblies, all cutting tools are driven by one cam driving assembly, etc.), and such a cam lathe has the advantages of compact structure, complex control logic, and difficult control, which results in slightly low machining precision. Here, each cutting tool is driven by one cam driving assembly independently, and the control logic is simpler, and the control is easier, so that the control precision of the feed amount of each cutting tool can be ensured, and the machining precision is improved.
The number of the cutting tools B2 and the cam driving assemblies B3 can be set according to actual needs, and the number of the cutting tools B2 and the cam driving assemblies B3 is not limited here. For example, in fig. 1, five cutting tools B2 and five cam drive assemblies B3 are provided.
In summary, although the present invention has been described with reference to the preferred embodiments, the above-mentioned preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and the embodiments are substantially the same as the present invention.
