[0030] 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.
[0031] Reference Figure 1 - Figure 3 The utility model provides an embodiment of a positioning fixture for punching circuit boards, comprising a punching machine 1, which can cooperate with a drill bit 2 to punch holes in circuit boards. A drill bit 2 is arranged above the punching machine 1, and a support block 41 is arranged at the top of the punching machine 1. The support block 41 provides support and can adjust the position of the circuit board by cooperating with a threaded screw 4. The top of the support block 41 is fixedly connected with a support plate 3, which provides support. A clamping assembly is arranged near the top of the support block 41 at the top of the punching machine 1, and the clamping assembly includes a bidirectional threaded rod 32. The bidirectional threaded rod 32 is threadedly connected with two groups of sliders 35 so that the two groups of sliders 35 can move in opposite directions. The middle part of the bidirectional threaded rod 32 passes through and is rotatably connected to the middle part of the support block 41. The outer wall of the bidirectional threaded rod 32 is threadedly connected with a slider 35. The slider 35 supports the clamping plate 31 and can drive the clamping plate 31 to move to clamp the circuit board.
[0032] Reference Figure 1 , Figure 2 An adjusting component is provided at the top of the punch 1, and the adjusting component includes a slide groove 43, and the slide groove 43 is opened at the top of the punch 1. The threaded screw 4 is slidably connected to the inner wall of the slide groove 43 to increase stability and provide support for the support block 41.
[0033] Reference Figure 2 - Figure 4 The slider 35 passes through and is slidably connected to the top of the support plate 3. The top of the slider 35 is fixedly connected to a clamping plate 31, which provides support. The left side of the clamping plate 31 is fixedly connected to a clamping rod 33 and two groups are provided. A clamping block 37 is slidably connected between the two groups of clamping rods 33. The two groups of clamping rods 33 support the clamping block 37. The top of the clamping block 37 is fixedly connected to a positioning plate 38. The bottom left end of the positioning plate 38 is set as an inclined surface, which can clamp the circuit board so that the circuit board is always positioned at the bottom, prevent the circuit board from sliding upward, and increase the stability of the clamping.
[0034] Reference Figure 1 , Figure 2 The support block 41 is slidably connected to the inner wall of the slide groove 43, and the front surface of the support block 41 is penetrated and threadedly connected with a threaded screw 4. The threaded connection between the threaded screw 4 and the support block 41 can adjust the position of the support block 41, so that the position of the circuit board can be adjusted to improve the accuracy. At the same time, the threaded screw 4 has good self-locking performance, so that the circuit board can remain stable and not easily displaced, thereby ensuring the stability and reliability of the punching operation.
[0035] Reference Figure 2 - Figure 4 The right side of the clamping block 37 is fixedly connected with a sliding rod 34, which supports the clamping block 37 and the spring 36. The sliding rod 34 passes through and is slidably connected to the right side of the clamping plate 31. The clamping block 37 is elastically connected to the clamping plate 31 through the spring 36, and the spring 36 can be squeezed after the clamping block 37 contacts the circuit board, so that the clamping force can be absorbed by the spring 36, thereby buffering the direct clamping of the circuit board, playing a buffering effect of the clamping force, and preventing the circuit board from being directly clamped and damaged. The clamping plate 31, the clamping rod 33, the clamping block 37, the positioning plate 38, and the sliding block 35 are provided in two groups, and the two groups of clamping plates 31, the clamping rod 33, the clamping block 37, the positioning plate 38, and the sliding block 35 are symmetrically arranged with the center line of the support plate 3 as the symmetry axis, so that the circuit board can be quickly clamped through cooperation, and the applicability is good.
[0036] Reference Figure 2 A fixing block 42 is fixedly connected to the top of the punching machine 1 near the rear of the slide slot 43 , and the threaded screw 4 is rotatably connected to the front surface of the fixing block 42 , and the threaded screw 4 is supported by the fixing block 42 .
[0037] Working principle: when in use, after placing the circuit board on the bottom end of the drill bit 2 above the support plate 3, the two-way threaded rod 32 is rotated, and the two-way threaded rod 32 is threadedly connected with the two sets of sliders 35, so that the two sets of sliders 35 can move inward, and the movement of the two sets of sliders 35 simultaneously drives the two sets of clamping plates 31, the clamping rod 33, and the clamping block 37 to move, and the two sets of clamping blocks 37 contact the circuit board and are squeezed by the circuit board, so that the two sets of clamping blocks 37 move the squeezing spring 36, and the circuit board is clamped by the reverse force of the squeezing of the spring 36, and the force of the circuit board being clamped is buffered, and at the same time, the circuit board is squeezed by the bottom end inclined surface of the positioning plate 38 after contacting the circuit board, so that the circuit board is always clamped at the bottom end, preventing the circuit board from sliding upward, and improving the stability of the clamping, and the circuit boards of different sizes can be clamped by rotating the two-way threaded rod 32, which is more convenient and improves the applicability and flexibility.
[0038] At this time, by rotating the threaded screw 4 and threadedly connecting the threaded screw 4 with the support block 41, the support block 41 can be moved to drive the support plate 3 to move. The movement of the support plate 3 can drive the circuit board clamped at the top to move, so that the position of the circuit board can be easily adjusted. After the adjustment is completed, the threaded screw 4 has good self-locking performance, so that the circuit board can remain stable and not easily displaced, thereby ensuring the stability and reliability of the punching operation.
