Description

Technical Field

[0001] The utility model relates to the technical field of hexagonal bolt processing, in particular to a slot milling and positioning tool for processing slotted hexagonal bolts. Background Art

[0002] Hexagonal displacement is a common problem in the production of hexagonal flange bolts. Hexagonal displacement is mainly caused by displacement of the hexagonal ejector during the third sequence ejection, resulting in a change in the hexagonal angle with the fourth sequence upper die. To address this phenomenon, a slot is added to the tail end to prevent rotation.

[0003] Conventional processing of hexagonal bolts usually only processes one product at a time, the processing efficiency is relatively low, and it is difficult to meet the needs of mass production. In addition, when positioning them, due to the low adaptability, they are prone to loosening, thus affecting normal processing. Utility Model Content

[0005] A milling slot positioning tool for processing slotted hexagonal bolts includes a base, a plurality of limit blocks are arranged on the base, and a limit column is fixed in the middle thereof, a placement seat is sleeved on the limit column, a plurality of placement slots are opened on the circumference of the placement seat, and bottom slots corresponding to the plurality of limit blocks are opened through the bottom of the plurality of placement slots, and a positioning plate that can be covered on the placement seat is also sleeved on the limit column, and the positioning plate is restricted to be tightly attached to the placement seat by a nut.

[0006] By adopting the above technical solution, it is convenient to position multiple hexagonal bolts at the same time, and the positioning operation is convenient.

[0007] A notch is provided in the middle of the positioning plate, and a through hole is provided at the center of the notch. The limiting column passes through the through hole. When the nut is installed on the limiting column, its bottom fits with the bottom of the notch, and a plurality of through holes corresponding to the placement slots are opened at the edge of the positioning plate.

[0008] By adopting the above technical solution, the hexagonal bolts can be positioned easily.

[0009] The upper end of the limit block is arranged as an inclined surface, and the width of the limit block is adapted to the width of the bottom groove.

[0010] By adopting the above technical solution, the bottom of the hexagonal bolt is positioned.

[0011] The upper end of the limiting column is a threaded structure, and the lower end is a cylindrical structure. The nut is rotated on the threaded structure of the limiting column.

[0012] By adopting the above technical solution, the positioning plate can be locked to achieve the positioning of the hexagonal bolt.

[0013] The plurality of limit blocks and the plurality of through holes are arranged in a ring array along the vertical center axis of the limit column.

[0014] By adopting the above technical solution, multiple hexagonal bolts can be placed and quickly positioned.

[0015] The beneficial effects of the milling slot positioning tool for processing a slotted hexagonal bolt of the utility model are:

[0016] Install the tooling at the predetermined position of the processing equipment, lift the placement seat upwards to disengage the limit block from the bottom slot, then fit the hexagonal bolt into the placement slot, lower the placement seat, place the positioning plate on the placement seat, pass the tail end of the hexagonal bolt through the through hole, and the limit column through the middle of the positioning plate. At this time, turn the nut onto the limit column and tighten it to fit the slot. At this time, the limit block limits the head edge of the hexagonal bolt, thereby completing the positioning of the hexagonal bolt, making it convenient to position multiple hexagonal bolts at the same time, and the positioning operation is convenient.

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0021] Reference Figure 1-2 A slot milling and positioning tool for processing a slotted hexagonal bolt comprises a base 1, a plurality of limit blocks 2 are arranged on the base 1, and a limit column 5 is fixed in the middle thereof, a placement seat 3 is sleeved on the limit column 5, a plurality of placement slots 301 are opened on the circumference of the placement seat 3, and bottom slots 302 corresponding to the plurality of limit blocks 2 are opened through the bottom of the plurality of placement slots 301, a positioning plate 4 which can be covered on the placement seat 3 is further sleeved on the limit column 5, and the positioning plate 4 is restricted to be tightly attached to the placement seat 3 by a nut 6;

[0022] Install the tooling at the predetermined position of the processing equipment, lift up the placement seat 3, disengage the limit block 2 from the bottom groove 302, then fit the hexagonal bolt into the placement groove 301, and then put down the placement seat 3. (It should be noted that the limit block 2 must correspond to the bottom groove 302), and then place the positioning plate 4 on the placement seat 3, so that the tail end of the hexagonal bolt passes through the through hole 401, and the limit column 5 passes through the middle of the positioning plate 4. At this time, turn the nut 6 onto the limit column 5 and tighten it to fit the notch 402. At this time, the limit block 2 restricts the edge of the head of the hexagonal bolt, thereby completing the positioning of the hexagonal bolt.

[0023] A notch 402 is provided in the middle of the positioning plate 4, and a through hole is provided at the center of the notch 402. The limiting column 5 passes through the through hole. When the nut 6 is installed on the limiting column 5, its bottom is fitted with the bottom of the notch 402, and a plurality of through holes 401 corresponding to the placement grooves 301 are opened at the edge of the positioning plate 4; to ensure that the limiting column 5 does not affect the normal processing of the straight groove on the tail end of the hexagonal bolt by external processing equipment, after the limiting block 2 passes through the bottom groove 302, when limiting the bottom of the hexagonal bolt, the height of the limiting column 5 is not more than 2 cm from the upper surface of the positioning plate 4, and the thickness of the nut 6 is equal to the depth of the notch 402, and the diameter of the nut 6 is set to be smaller than the diameter of the notch 402.

[0024] The upper end of the limit block 2 is provided with an inclined surface, and the width of the limit block 2 is adapted to the width of the bottom groove 302. The inclined surface of the limit block 2 is arranged toward the limit post 5. After the hexagonal bolt is placed, the placement seat 3 can be lowered, so that the limit block 2 passes through the corresponding bottom groove 302 and restricts the bottom of the hexagonal bolt.

[0025] The upper end of the limiting column 5 is a threaded structure, and the lower end is a cylindrical structure. The nut 6 rotates on the threaded structure of the limiting column 5; the placement seat 3 can move up and down along the limiting column 5, so that the hexagonal bolt can be placed on the placement seat 3 and the bottom of the hexagonal bolt can be positioned.

[0026] Multiple limit blocks 2 and multiple through holes 401 are arranged in a circular array along the vertical center axis of the limit column 5. According to the above arrangement, multiple hexagonal bolts can be placed and positioned at the same time, and the positioning operation is simple while ensuring the stable positioning of the hexagonal bolts.

[0027] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
