[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments; based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

They are used only for the convenience of describing the invention 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 the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0031] refer to Figures 1-7 The bidirectional vernier adjustable drill press pliers described in this embodiment include a plier base 1, a plier body 2, an X-axis moving mechanism 3, a Y-axis moving mechanism 4, and a limiting mechanism 5. A dovetail groove 102 is provided on the upper part of the plier base 1. The dovetail groove 102 and the dovetail protrusion 204 on the lower part of the plier body 2 are nested and engaged, so that the plier body 2 can slide along the X direction.

[0032] This invention incorporates the reading principle of a vernier caliper. A first auxiliary ruler 1-1 is installed on the side wall of the clamp base 1 along the X direction. A first scale 1-2 is assembled on the clamp body 2 at the opposite position. The clamp body 2 is moved by rotating the first handwheel 304 on the X-axis moving mechanism, and the relative distance between the clamp body 2 and the clamp base 1 is controlled by observing the reading value on the first scale 1-2. This relative distance is equal to the distance from the center of the pre-made hole of the pre-made workpiece A to the reference side perpendicular to the X-axis direction (the reading value on the first scale 1-2 is also this distance value).

[0033] Similarly, in this invention, a second auxiliary ruler 1-3 is installed on the fixed jaw 201 along the Y direction, and a second scale ruler 1-4 is assembled on the limiting mechanism 5 at the opposite position. The starting end of the scale of the second scale ruler 1-4 is fixedly connected to the limiting mechanism 5, and the other end slides through the reserved channel at the bottom of the fixed jaw 201. During the sliding process, the scale surface always abuts against the second auxiliary ruler 1-3 on the fixed jaw 201.

[0034] According to the interaction relationship between the components in the X-axis moving mechanism, the rectangular nut 301 arranged on the jaw seat 1 cooperates with the first rectangular lead screw 302 in the X-axis moving mechanism, the first connecting block 303 in the X-axis moving mechanism is fixed on the jaw body 2 by bolts, so that the whole X-axis moving mechanism 3 remains relatively stationary with the jaw body 2, the first rectangular lead screw 302 in the X-axis moving mechanism is fixed with the first hand wheel 304 in the X-axis moving mechanism by screws, and the X-axis moving mechanism 3 pushes the jaw body 2 to move along the X direction by rotating the first hand wheel 304 for adjustment.

[0035] According to the interaction relationship between the components in the Y-axis moving mechanism, the second rectangular lead screw 401, the first guide rod 402 and the second connecting block 403 on the Y-axis moving mechanism cooperate, the second rectangular lead screw 401 on the Y-axis moving mechanism is fixed with the second hand wheel 404 on the Y-axis moving mechanism by screws, and the Y-axis moving mechanism 4 pushes the stop block mechanism 5 to move along the Y direction by rotating the second hand wheel 404 for adjustment. The stop block 501, which is the positioning reference edge in the Y direction, is connected to the guide rail 502 of the limiting mechanism 5, a groove is opened below the stop block 501, and the groove is embedded in the guide rail 502 so that the stop block 501 can slide on the guide rail 502.

[0036] Specifically, the second rectangular lead screw 401, the first guide rod 402 and the second connecting block 403 on the Y-axis moving mechanism 4 cooperate at one end and are connected to the stop block 501, which is the positioning reference edge in the Y direction, through the abutting connecting plate 503 at the other end. By rotating the second hand wheel 404 on the Y-axis moving mechanism, the stop block mechanism 5 is pushed, and the reading value on the second scale 1-4 is observed to move the stop block mechanism 5 to the desired position. At this time, the reading value on the second scale 1-4 is equal to the distance from the center of the preformed hole of the preformed workpiece A to the reference edge perpendicular to the Y-axis direction.

[0037] According to the interaction relationship between the components on the jaw body, the second guide rod 203 installed on the jaw body 2 cooperates with the guide rod hole below the movable jaw 202, so that the movable jaw 202 can move along the X-axis on the second guide rod 203, while ensuring that the lower surface of the movable jaw 202 is in contact with the sliding surface 205 of the jaw body. The third rectangular lead screw 206 installed on the movable jaw 202 cooperates with the rectangular threaded hole arranged on the jaw body 2, a through hole is opened at the tail end of the third rectangular lead screw 206, and a handle 207 is installed on the through hole. The movable jaw 202 is moved along the X-axis by rotating the handle 207, interacts with the fixed jaw, and achieves the purpose of clamping the preformed workpiece A.

[0038] To be precise, this invention combines the reading principle of vernier calipers and designs the fixed jaws 201 and the stop 501 (i.e., the two reference edges) of the flat-jaw vise as reference edges that can move according to the pre-made hole size. No matter how the hole size changes, as long as the two reference edges are moved to the corresponding size distance of the drill bit axis, the center of the hole can always be located at the axis of the drill bit. This allows the pre-made workpiece to be placed in, clamped, and the required hole to be drilled directly. By designing the stop to be movable, it can cope with most of the reference changes on the workpiece to a certain extent.

[0039] Considering that this invention is a machine tool accessory for drilling operations on a machine tool, it needs to be stably fixed or placed on the machine tool's worktable. Therefore, this invention has U-shaped grooves 101 on the four sides of the clamp seat 1, which can be fixed on the worktable of the drilling machine. The clamp is engaged with the machine tool on all four sides through the U-shaped interface, which can firmly fix the relative position of the flat jaw clamp assembly on the machine tool and ensure stability during the cutting and drilling process.

[0040] The method for using the bidirectional vernier-adjustable drilling machine vise according to the present invention includes the following specific steps:

[0041] Step 1: Based on the distance from the center of the pre-made hole of the pre-made workpiece A to the reference side perpendicular to the X-axis direction, rotate the first handwheel 304 on the X-axis moving mechanism to adjust the relative distance between the clamp body 2 and the clamp seat 1 so that the reading on the first scale 1-2 meets the requirements.

[0042] Step 2: Based on the distance from the center of the pre-drilled hole of pre-made workpiece A to the reference edge perpendicular to the Y-axis, rotate the second handwheel 404 on the Y-axis moving mechanism to move the limiting mechanism 5 to the corresponding position, so that the reading on the second scale 1-4 meets the requirements;

[0043] Step 3: According to the required clamping height of the prefabricated workpiece A, place the corresponding equal height pads B at both ends of the fixed jaw 201 and the movable jaw 202. At the same time, place the two reference edges of the prefabricated workpiece A against the fixed jaw 201 and the adjusted stop block 501 respectively, and rotate the handle 207 on the rectangular screw to clamp the workpiece A.

[0044] Step 4: The intersection point of the perpendicular line segment between the scale line where the reading of the first scale 1-2 is located and the scale line where the reading of the second scale 1-4 is located is the processing point of the center of the pre-made hole to be processed.

[0045] Step 5: Based on the position of the center of the pre-made hole to be processed, directly drill out the required hole position.

[0046] The above merely describes preferred specific embodiments of the present application, but the design concept of the present application is not limited thereto, and any person skilled in the art, within the technical scope disclosed by the present application, can make non-essential modifications to the present application using the concept, and such modifications shall not be deemed to be within the scope of the present application.
