Hardware tools often need to be drilled during the production and manufacturing process. When drilling, flat-nose pliers are required to fix the workpiece, and then a vertical drilling machine is used to drill. Flat-nose pliers are mainly composed of a pliers body, a fixed pliers body, a movable pliers body and a screw. The workpiece is placed between the fixed pliers body and the movable pliers body, and then the screw is turned to move the movable pliers body, thereby clamping and fixing the workpiece. Flat-nose pliers are fixed tooling for drilling holes in hardware tools.
[0003] When the common hardware tool punching fixture is in use, when the same type of hardware tools are manufactured in large quantities, the size of the workpieces used to manufacture the hardware tools is the same. When punching the workpiece, it is difficult to ensure that the drilling position of the workpiece is aligned with the drill bit of the vertical drilling machine when the workpiece is directly fixed by flat-nose pliers. The flat-nose pliers lack a side positioning mechanism for the workpiece to align the drilling position of the workpiece with the drill bit of the vertical drilling machine. The position of the workpiece needs to be continuously adjusted each time it is fixed, and the convenience of use needs to be improved. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4 The utility model discloses a fixed tool for punching holes with hardware tools, comprising a flat-nose pliers body 1 and a fixed pliers body 2 fixed on the flat-nose pliers body 1, and also comprising:
[0023] The side positioning mechanism 3 is used to position the end of the workpiece to ensure that the position of the workpiece to be punched is aligned with the drill position of the vertical drilling machine, thereby facilitating the use of the flat-nose pliers body 1. The side positioning mechanism 3 includes a guide sleeve 32 fixed to the side of the fixed pliers body 2. The inner wall of the guide sleeve 32 is slidably connected with a square bar 31. The guide sleeve 32 is used to guide the square bar 31 during its movement. The square bar 31 is engraved with scale lines 37. A positioning block 35 is fixed at the end of the square bar 31. An indicator block 36 aligned with the scale line 37 is fixed on the side of the fixed pliers body 2. The distance between the punching position on the workpiece and the end of the workpiece is measured, and then the square bar 31 is moved to observe the value of the indicator block 36 corresponding to the scale line 37. When the value of the scale line 37 plus the value of half the length of the fixed pliers body 2 is equal to the value of the punching position of the workpiece from the end of the workpiece, it can be ensured that the punching position of the workpiece is aligned with the drill position. A locking member 34 for fixing the square bar 31 is provided on the side of the fixed pliers body 2. The locking member 34 is used to fix the square bar 31.
[0024] Specifically, a guide block 33 is fixed to the inner wall of the guide sleeve 32 , and the inner wall of the guide groove formed at the bottom of the square bar 31 is slidably connected to the surface of the guide block 33 .
[0025] In this implementation plan, please refer to Figure 3 When the square bar 31 moves, it moves along the surface of the guide block 33. The guide block 33 guides the movement of the square bar 31, so that the movement of the square bar 31 is more stable and smooth.
[0026] Specifically, the guide block 33 is E-shaped, and the shape of the guide groove provided at the bottom of the square bar 31 matches the shape of the guide block 33 .
[0027] In this implementation plan, please refer to Figure 3 The E-shaped guide block 33 is used to increase the contact area with the inner wall of the guide groove at the bottom of the square bar 31, thereby improving the guiding stability of the square bar 31.
[0028] Specifically, a limiting block 4 is fixed to one end of the square bar 31 away from the positioning block 35 to prevent the square bar 31 from being separated from the guide sleeve 32 .
[0029] In this implementation plan, please refer to Figure 1 The limit block 4 is fixed at the end of the square bar 31 to prevent the square bar 31 from being separated from the guide sleeve 32 when the square bar 31 is pulled.
[0030] Specifically, the central axis of the square bar 31 and the central axis of the fixed clamp body 2 are parallel to each other.
[0031] In this implementation plan, please refer to Figure 3 and Figure 4 , ensuring the accuracy of measuring the moving distance of the positioning block 35 after the square bar 31 moves.
[0032] Specifically, the locking member 34 includes an internal thread block 342 fixed to the side of the fixed clamp body 2 , and the inner wall of the internal thread block 342 is threadedly connected with a bolt 341 for fixing the square bar 31 .
[0033] In this implementation plan, please refer to Figure 4 The internal thread block 342 is threadedly connected with the bolt 341 , and the bolt 341 rotates and moves to abut against the side of the square bar 31 , thereby fixing the square bar 31 .
[0034] Specifically, a locking plate 343 is fixed to the end of the bolt 341 , and a side surface of the locking plate 343 is movably connected to a side surface of the square bar 31 .
[0035] In this implementation plan, please refer to Figure 4 The locking plate 343 is used to increase the contact area between the bolt 341 and the square bar 31, thereby improving the fixing stability of the square bar 31.
[0036] The working principle and use process of the utility model are as follows: the distance between the punching position on the workpiece and the end of the workpiece is measured, and the distance between the positioning block 35 on the square bar 31 and the indicator block 36 is adjusted according to the distance value. When adjusting, the bolt 341 needs to be rotated first to separate the locking plate 343 from the square bar 31, and then the square bar 31 is moved to observe the value of the scale line 37 corresponding to the indicator block 36. When the value of the scale line 37 plus the value of half the length of the fixed clamp body 2 is equal to the value of the distance between the punching position of the workpiece and the end of the workpiece, the bolt 341 can be rotated in the opposite direction to make the locking plate 343 press against the square bar 31, fix the square bar 31 and the positioning block 35, and then place the workpiece between the fixed clamp body 2 and the movable clamp body so that the end of the workpiece fits with the positioning block 35. After the workpiece is fixed, it can be ensured that the punching position of the workpiece is aligned with the drill position.
[0037] After the processing is completed, the workpiece can be taken out from the fixed clamp body 2 and the movable clamp body. When the square bar 31 moves, it moves along the inner wall of the guide sleeve 32 and the surface of the guide block 33. The guide sleeve 32 and the guide block 33 guide the movement of the square bar 31, making the movement of the square bar 31 more stable and smooth.
