Description

[Technical Field]

[0001] The present invention particularly relates to a positioning device, and is a technical improvement of a positioning device used to position a member to be positioned. [Background technology]

[0002] The positioning device can be used in fields such as precision machining, CNC machining, mold manufacturing, five-axis machining, etc. An article (e.g., a positioning jig, a vice, a jig, a workpiece, a tool, a mold, etc.) can be positioned on the positioning device, and accurate positioning can be maintained even when the article is transferred between different positioning devices or repeatedly attached to the same positioning device.

[0003] In conventional positioning devices, the tapered first guide surface of the guide pillar moves axially, pressing multiple steel balls radially against the first and second locking members to move the first and second insert pillars. However, the guide pillar pressing the steel balls and the multiple steel balls pressing the first and second locking members are both point-to-point contacts, which can easily cause uneven force during the pressing process and vibration in the first and second locking members, preventing smooth movement and preventing reliable locking of the first and second insert pillars. Furthermore, in the prior art, the guide pillar needs to align the steel balls inside during the installation process, but this is invisible to the installer, making misalignment a possibility.

[0004] Therefore, it is necessary to provide a new and innovative positioning device to solve the above problems. Summary of the Invention [Problem to be solved by the invention]

[0005] The main object of the present invention is to provide a positioning device that can stably move two positioning members and stably receive forces, is easy to install, and has a simple structure. [Means for solving the problem]

[0008] The following describes possible embodiments of the present invention only by way of examples, but does not limit the scope of protection of the present invention. The words "one" or "at least one" before the nouns mentioned in this specification do not limit the number, and may be "plurality" as needed. Changes in this number are also within the scope of protection, as will be explained below.

[0009] 1 to 5, which show a first embodiment of the present invention, a positioning device 1 of the present invention includes a main body 10, a positioning module 20, and an adjustment module 30.

[0010] The main body 10 includes a plurality of positioning holes 11, receiving grooves 12 (blind grooves), and at least one sliding groove 13. The positioning module 20 includes two positioning members 21, which are disposed in the at least one sliding groove 13 and can respectively move along the at least one sliding groove 13 relative to the at least one positioning hole 11. The adjustment module 30 includes a first screw 31, a second screw 32, and an interlocking member 33, which are rotatably mounted on the main body 10, the first screw 31 including a first threaded portion 311 and a first bevel gear 312, and the second screw 32 including a second threaded portion 321 and a second bevel gear 322, and the two positioning members 21 are threaded onto the first threaded portion 311 and the second threaded portion 321, respectively. In this embodiment, the first threaded portion 311 and the second threaded portion 321 are spirally arranged in opposite directions. The interlocking member 33 is rotatably arranged in the accommodating groove 12 and includes a first end 331 and a second end 332. The first end 331 has a third bevel gear 333, which faces the groove mouth 121 of the accommodating groove 12 and the second end 332 faces the groove bottom 122 of the accommodating groove 12. The third bevel gear 333 meshes between the first bevel gear 312 and the second bevel gear 322.

[0011] This allows the two positioning members to move stably and bear force stably, and the interlocking member 33 is positioned and restricted by the groove bottom 122 of the accommodating groove 12, thereby simplifying the number of parts and processing steps. Furthermore, the meshing state of the third bevel gear 333 of the interlocking member 33 with the first bevel gear 312 and the second bevel gear 322 can be directly observed from the groove opening 121 of the accommodating groove 12, facilitating accurate alignment and clearance adjustment and installation. Furthermore, a portion of the interlocking member 33 adjacent to the third bevel gear 333 annularly contacts the groove wall of the accommodating groove 12, limiting and stabilizing its center, allowing the first bevel gear 312 and the second bevel gear 322 to mesh stably and smoothly transmit power.

[0012] Preferably, the first extension dimension E1 of the interlocking member 33 is smaller than the second extension dimension E2 of the receiving groove 12, so that it can be confined in a small space, save materials, and rotate stably.

[0013] The adjustment module 30 further includes a closing member 34 that closes the groove opening 121, effectively preventing dust and debris, and providing convenient quick installation and removal with high thread locking strength. In this embodiment, the groove wall of the receiving groove 12 is provided with a female thread structure 123 adjacent to the groove opening 121. The closing member 34 has a male thread structure 341 that is threaded into the female thread structure 123 to close the groove opening 121. Preferably, the closing member 34 is a set screw, which can be easily removed with a tool. In another embodiment, as shown in FIG. 7 , the closing member 34a includes a cover 342 and a locking member 343. The cover 342 closes the groove opening 121 of the receiving groove 12a, and the locking member 343 is threaded into a thread locking hole of the main body 10a to lock the cover 342 to the main body 10a.

[0014] In this embodiment, the main body 10 includes two sliding grooves 13, which are provided on opposite sides of the main body 10 and spaced apart in the installation direction L2, and which open to different sides of the main body 10, and two positioning members 21 are provided in the two sliding grooves 13, respectively, and the receiving groove 12 extends transversely to the installation direction L2 (which is perpendicular in this embodiment) and is located between the two sliding grooves 13. In this embodiment, the main body 10 has a first end wall 15 and a second end wall 16 provided on opposite sides, and a peripheral wall 17 of the main body 10 is connected transversely between the first end wall 15 and the second end wall 16, which are provided in the first direction L1, and the two sliding grooves 13 open to opposite sides of the peripheral wall 17. The two positioning members 21 can pass through the two openings 131 of the two sliding grooves 13, respectively. Preferably, the main body 10 further includes two receiving holes 14, each of which is transverse to the receiving groove 12 and communicates between one of the sliding grooves 13 and the receiving groove 12, the first screw 31 and the second screw 32 are respectively disposed in the two receiving holes 14, and the first bevel gear 312 and the second bevel gear 322 are respectively inserted into the receiving groove 12. Specifically, a portion of the first screw 31 adjacent to the first bevel gear 312 and a portion of the second screw 32 adjacent to the second bevel gear 322 annularly abut against the hole wall of one of the receiving holes 14, thereby achieving stable radial support. The first screw 31 is connected to one of the positioning members 21, and the second screw 32 is connected to the other positioning member 21, and they can be inserted from opposite sides of the main body 10, making installation easy.

[0015] More specifically, the two positioning members 21 can pass through two openings 131 of the two sliding grooves 13, respectively. An end of the first screw 31 is drilled into one of the sliding grooves 13 and is provided with a first coupling hole 314 (e.g., a hexagonal socket or a hexalobular socket), and an end of the second screw 32 is drilled into one of the sliding grooves 13 and is provided with a second coupling hole 324 (e.g., a hexagonal socket or a hexalobular socket), the first coupling hole 314 is exposed to the opening 131 of one of the sliding grooves 13, and the second coupling hole 324 is exposed to the opening 131 of the other sliding groove 13, and the first coupling hole 314 and the second coupling hole 324 are each provided for coupling with a tool (a hexagonal wrench or an electric screwdriver). In this way, the structural strength of the middle region of the main body 10 is high (the top, bottom and center are connected), and the two positioning members 21 and the interlocking member 33 are in independent spaces and do not interfere with each other, so they can be easily attached and detached independently and do not affect each other.

[0016] Preferably, the positioning module 20 further includes two annular rings 50, each fitted to the positioning member 21, each annular ring 50 annularly abutting the inner circumferential wall of one of the sliding grooves 13, each annular ring 50 being a rubber ring for sealing and anti-skid purposes.

Preferably, the first screw 31 is provided with a first annular groove 313, and the second screw 32 is provided with a second annular groove 323. The stoppers 40 are respectively engaged with the first annular groove 313 and the second annular groove 323, thereby restricting the first screw 31 from moving in the direction of extension thereof and restricting the second screw 32 from moving in the direction of extension thereof.

[0018] Specifically, the plurality of positioning holes 11 are at least partially disposed at corners of the at least one sliding groove 13, and each of the positioning members 21 includes at least one locking portion 211. The plurality of positioning holes 11 are used to insert a plurality of plug rods 3 of a member to be positioned 2 (e.g., a positioning jig, a vice, a jig, a member to be processed, a tool, a mold, etc.). The two positioning members 21 are respectively moved by the first screw 31 and the second screw 32 relative to the plurality of positioning holes 11 between a locked position and an unlocked position. When the two positioning members 21 are in the locked position, the at least one locking portion 211 of each of the positioning members 21 protrudes into one of the positioning holes 11 and is used to engage with the recess 4 of the plug rod 3 located in the positioning hole 11. When the two positioning members 21 are in the release positions, the locking portions 211 of the positioning members 21 are disengaged from the grooves 4 of the plug rod 3, thereby achieving the effect of quick positioning and disengagement.

[0019] In use, one of the first screw 31 and the second screw 32 is driven, and the interlocking member 33 is moved and rotated to move and rotate the other of the first screw 31 and the second screw 32, and the plurality of positioning members 21 are further driven to move between the locked position and the released position, so that the positioning target member 2 is positioned and locked, and the positioning members 21 are unlocked.
