Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spring bar mounting hole drilling device particularly suitable for drilling a hole for mounting a spring bar in a watch case.

0002

[Prior Art] Conventionally, a slider is movably disposed on the top of a slide table, a pair of drill units are rotatably disposed on the top of the slider, and the drill units are driven above the drill units. A spring bar mounting hole drilling device equipped with a motor is known.

0003

[Problems to be Solved by the Invention] However, in the conventional spring bar mounting hole-drilling device, when the drill unit is used to drill a hole in the band mounting portion of the watch case, which is the workpiece, the tip of the drill of the drill unit is inserted into the watch case. Since the hole was set at the hole for the band attachment part of the watch case using the center as the reference position, even if there is an error in the amount of protrusion of the band attachment part of the watch case, the hole can be drilled at a certain point from the tip of the band attachment part of the watch case. It is not possible to drill holes using the drill unit's drill, and the processing conditions such as the rotation speed of the drill unit's drill and the feed status of the slider relative to the slide base cannot be adapted to the material of the watch case, so the life of the drill can be extended. Therefore, it was impossible to drill a deep hole in the band attachment part of the watch case using a drill, and it was inconvenient to adjust the height of the drill unit of the watch case to the drill.

An object of the present invention is to solve the above-mentioned problems by moving the abutment member along the moving direction of the first movable member, thereby aligning the central axis of the drill unit with the tip of the abutment member. The distance between the two is adjusted according to the position of the hole drilled by the drill unit with respect to the band attachment part of the watch case, and at the same time as the first movable member moves toward the frame toward each other, the second movable member moves toward the second movable member. The drill unit moves together with the first movable member in a direction close to each other, the drill unit moves together with the second movable member in a direction close to each other, and the abutment member moves together with the first movable member in a direction close to each other. Even if there is an error in the amount of protrusion of the band attachment part of the watch case, the tip of the abutment member will come into contact with the tip of the band attachment part of the watch case, and the tip of the abutment member will not touch the drill unit against the band attachment part of the watch case. is positioned at a predetermined hole-drilling position with reference position, and the second movable member moves toward the front of the frame intersecting the first movable member, and at the same time, the drill unit and the second movable member move toward the front of the frame. An object of the present invention is to provide a spring bar mounting hole drilling device that can move toward the front of the watch case and drill holes for spring bar mounting at a fixed location of a band mounting portion of a watch case using a drill unit.

[0005]

[Means for Solving the Problems] The spring bar mounting hole-drilling device of the present invention includes a pair of first movable members disposed in a frame so as to be able to approach and separate from each other, and the first movable members A second movable member is disposed on the top of the movable member so as to be movable in a direction intersecting the first movable member, a drill unit is provided on the second movable member, and an abutment member is provided on the first movable member. The structure is characterized in that the first movable member is movable and fixed in the direction of movement of the first movable member.

[0006]

[Operation] The abutment member provided on the first movable member so as to be movable and fixed in the direction of movement of the first movable member is moved along the direction of movement of the first movable member, and the abutment member is moved in the direction of movement of the first movable member, and the abutting member Adjust the distance from the tip of this member to match the position of the hole to be drilled by the drill unit to the band attachment part of the watch case.

[0007] Furthermore, when the pair of first movable members, which are disposed on the frame so as to be able to approach and separate from each other, are moved in the direction of approaching each other with respect to the frame, the first movable member is placed above the first movable member. A second movable member disposed movably in a direction intersecting the movable member moves in a direction approaching each other together with the first movable member, and at the same time, a drill unit provided on the second movable member moves toward the second movable member. The abutment members move together with the first movable member in a direction approaching each other, and the tip of the abutment member abuts the tip of the band attachment part of the watch case, and the drill unit is positioned at a predetermined hole-drilling position with the tip of the abutting member relative to the band attachment portion of the watch case as a reference position.

Further, at the same time as the second movable member moves toward the front of the frame intersecting with the first movable member, the drill unit moves together with the second movable member toward the front of the frame. Drill holes for spring bar attachment using a drill unit at certain locations on the band attachment part of the case.

Furthermore, by changing the cam 118,
It is also possible to change the state in which the vertical sliders 3, 3 are fed forward with respect to the slide bases 13, 13 by the step motor M2. For example, by giving forward and reverse rotation to the step motor M2, the forward movement of the vertical slider 3 can be changed. It is also possible to provide intermittent step feed to the feed, and the drill units 4, 4 can be attached to one band attachment portion 284, 284 and the other band attachment portion 285, 285 of the watch case 283.
It is also possible to drill long straight holes in four consecutive locations using the drills 76 and 76, or to drill long straight holes in the comb-shaped band attachment part of a watch case using the drill unit. be.

[0200]

As described above, according to the spring bar mounting hole-drilling device of the present invention, by moving the abutment member along the moving direction of the first movable member, the center of the drill unit can be moved. The distance between the shaft and the tip of the abutting member can be adjusted according to the position of the hole drilled by the drill unit with respect to the band attachment part of the watch case, and the first movable members are moved closer to each other with respect to the frame body. At the same time as moving
The second movable members move together with the first movable member in a direction closer to each other, the drill units move together with the second movable member in a direction closer to each other, and the abutment members move together with the first movable member towards each other. Since they move in adjacent directions, even if there is an error in the protrusion amount of the band attachment part of the watch case, the tip of the abutment member will come into contact with the tip of the band attachment part of the watch case, and the drill unit will be attached to the band of the watch case. The second movable member can be positioned at a predetermined hole drilling position with the tip of the abutment member as a reference position, and at the same time as the second movable member moves toward the front of the frame intersecting with the first movable member, Since the drill unit moves toward the front of the frame together with the second movable member, the drill unit can drill a hole for attaching the spring bar at a certain location on the band attaching portion of the watch case.

[0201] By adapting the machining conditions of the motor that drives the drill unit and the step motor that moves the second movable member relative to the first movable member depending on the material of the workpiece, the drill of the drill unit can be adjusted. It is possible to increase the service life, and it is possible to shorten the time for setting machining conditions and the time for machining the workpiece with a drill.
