As a result, by the function of the stopper member 82, it is possible to prevent any movement of the movable bar 64 as well as the first and second support guide bars 60 and 62 in the work table direction, 52 and the main spindle 70. [0031] In addition,

A spindle head 72 having a spindle 70 in the direction of the work table 52 is fixedly connected to one end of the movable bar 64. A spindle shift lever 84 is provided on one side of the spindle head 72 so as to horizontally move the main spindle 70 itself for engaging and rotating the rotating tool in parallel with the work table 52 have.

That is, when the worker operates the spindle moving lever 84, the spindle 70 moves horizontally within the spindle head 72 accordingly.

The structure in which the spindle 70 is moved by operating the spindle moving lever 84 as described above is only a known technique in which the interlocking structure between the main spindle and the spindle moving lever provided in a general drilling machine or tapping machine is applied as it is. A concrete connection between the main shaft 70 and the main shaft moving lever 84 is omitted.

A driving pulley 90 coupled to the driving shaft 88 of the driving motor 74 and a driving pulley 90 coupled to the main shaft 70 are provided in the driving force transmitting portion 76 provided with the driving motor 74, A belt 94 for interlocking rotation is wound between the drive pulley 90 and the transmission pulley 92. [

Therefore, when the driving shaft 88 rotates by the driving of the driving motor 74, the driving pulley 90 and the transmission pulley 92 rotate together to rotate the main shaft 70 Hole machining can be performed.

The lower end of the first moving plate 80a is fixed with a coupling portion 96b having a spiral hole 96a formed therein and a connecting member 86 And is connected to the lower direction.

An X axis or a spindle member 98 is passed through the spiral hole 96a of the fastening portion 96b and both ends of the X axis and the spindle member 98 are fixed to both sides of the work table 52 And is rotatably coupled to the support member 100. [

Therefore, when the X-axis transport handle 102 provided at one end of the X-axis or the spindle member 98 is rotated, the X-axis or the spindle member 98 rotates in place, and the first moving plate 80a Axis direction along the X-axis or the spindle member 98, and the horizontal EL block 56 moves along the horizontal EL display 54 in association with the movement.

As shown in FIGS. 3A and 4B, a buffer supporting means 108 composed of a cylinder 104 and a rod 106 is fixedly connected between the connecting member 86 and the second moving plate 80d.

Specifically, the lower end of the connecting member 86 is provided with a fastening boss 110, and the fastening boss 110 is fastened to the fastening boss 110 in a state where the lug 112 provided at the end of the cylinder 104 is abutted. And is fastened through a fastening bolt 114 fastened by a fastening bolt.

The rod 106 drawn out from the cylinder 104 is moved in a state in which the lug 116 provided at the end of the rod 106 is brought into contact with the coupling portion 118 provided in the second moving plate 80d The fastening bolt 120 is fastened to the fastening part 120 through the lug 116. [

A packing body 124 having an orifice hole 122 is movably accommodated in a cylinder 104 installed as described above so as to move in a state of pressing the inner surface of the cylinder 104. The packing body 124 Are connected such that the aforementioned rod 106 is interlocked.

In addition, any one of fluid, that is, oil or air, is filled in the cylinder 104 in a sealed state.

The provision of the cushioning support means 108 as described above allows the fluid 126 to bear the position of the packing body 124 and the fluid 126 to retain the packing 126 when the strong vibration or shock is transmitted, The load generated when the fluid passes through the orifice hole 122 of the body 124 is mixed with each other, so that the movement of the packing body 124 is mitigated and restrained.

Accordingly, it is possible to further prevent the strong vibration or impact of the first and second moving plates 80a and 80d during the hole machining, thereby making it possible to restrain the overall shaking of the horizontal side machining apparatus 50 It is possible to improve the durability with accurate and precise hole machining.

On the other hand, a support part 128 is provided at the lower end of the first moving plate 80a. The Y-axis conveying handle 130 is provided on the Y- Are connected in a state of being able to rotate in place. The Y-axis or spindle member 132 is fastened to the fastening portion 134 formed on the lower bottom surface of the second moving plate 80d.

Accordingly, when the Y-axis transport handle 130 is rotated, while the Y-axis or the spindle member 132 interlocking with the Y-axis transport handle 130 is rotated in the direction of fastening or releasing by the fastening portion 134, Axis direction along the Y-axis or the spindle member 132 in the Y-axis direction. (See Figs. 5A and 5B)

If the horizontal side machining device 50 having the above structure is used, the vertical machining device of the prior art document 1 and the tapping drilling machine of the prior art document 2, the workpiece placed for hole machining approaches the main shaft Or if a vertical height exceeding the main axis is to be formed, it is difficult to perform the hole machining itself or the hole machining required due to the limit of the hole machining depth.

However, in the horizontal side-face processing apparatus 50 according to the present invention, the workpiece is horizontally laid down on the work plate 78 so that the hole-processed side faces the horizontal direction parallel to the work table 52, The main spindle 70 to which the rotary tool is coupled together and the spindle head 72 are moved in the direction of the work table 52 in the direction parallel to the work plate 78, , And the problems raised in the type of prior art document 2 can be overcome.

In the vertical machining apparatus of the prior art document 1 and the tapping drilling machine of the prior art document 2, when the hole is machined in a state where the workpiece is vertically erected, when the vertical height of the workpiece is high, Only the lower end portion of the workpiece is held using the fixing means (for example, a fixing jig or a vise) provided therein, so that the upper end portion of the workpiece is shaken at the time of hole machining, so that accurate and precise hole machining can not be achieved.

However, in the horizontal side processing apparatus 50 according to the present invention, the workpieces are horizontally laid down so that the workpieces can be stably supported by an increased area of the workpieces 78 being closely contacted and supported. When the workpiece is horizontally disposed, the workpiece can be fixed to the workpiece 78 along the circumference of the workpiece, so that the workpiece can be firmly fixed to the workpiece, thereby enhancing the precision of the hole machining.
