Description

Technical Field

[0001] This utility model relates to the field of dotting fixtures, specifically to a high-precision measuring dotting fixture. Background Technology

[0002] Currently, when machining screw holes on long pads under molds, the conventional method to save costs is to manually measure and scribing to find the hole locations before drilling and tapping. However, when there are many pads and the mold assembly deadline is tight, this method is inefficient and carries the risk of errors.

[0003] In addition, manual marking and drilling is often done by non-experienced technicians, such as apprentices, because the operation is simple. Apprentices often make mistakes in marking due to their lack of experience, which makes it impossible for the pads and mold bases to connect properly. This requires plugging the holes and drilling again, which is very troublesome.

[0004] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0007] A high-precision measuring and marking fixture includes a plate with a reference marking hole and several free marking holes through it along its length. Each marking hole is provided with a corresponding scale value.

[0008] The plate is detachably provided with an end positioning block at one end along its length. The end positioning block is close to the reference dot hole side and perpendicular to the plate, forming a right-angled surface that matches the width direction of the pad product.

[0009] The plate is detachably provided with several side positioning blocks on both sides along its width direction. The side positioning blocks are driven linearly to move along the width direction of the plate. The side positioning blocks are perpendicular to the plate and form a right-angled surface that matches the length direction of the pad product.

[0010] Preferably, the lower end of the side wall of the end positioning block near the flat plate is provided with a first inclined surface, which gradually slopes from top to bottom toward the side away from the flat plate.

[0012] Preferably, the end positioning block is detachably connected to the plate by screws.

[0013] Preferably, at least one magnet is embedded in the inner wall of the end positioning block, which serves as a component for fixing and adsorbing the foot pad product.

[0014] Preferably, the linear drive includes a long bolt, one end of which passes through the side positioning block and is threadedly connected to a screw hole on the plate. The long bolt is rotatably engaged with the side positioning block via a bearing.

[0015] More preferably, the linear drive located on one side of the plate width direction further includes an elastic structure that abuts against the bolt cap and the side positioning block.

[0016] More preferably, the elastic structure includes a spring, which is sleeved on the long bolt, and both ends of the spring abut against the bolt cap and the side positioning block, respectively.

[0017] Preferably, the flat plate has grooves on both side walls in the width direction, and the grooves serve as guides and positions for the side positioning blocks.

[0018] Preferably, the scale value is a scale groove structure formed on the plate.

[0019] The working principle and advantages of this utility model are as follows:

[0036] See appendix Figure 1-5As shown, a high-precision measuring and marking fixture includes a plate 1. A reference marking hole 11 and several free marking holes 12 are formed through the plate 1 along its length. Each marking hole is provided with a scale value 13, which can start from one end edge of the plate 1 along its length.

[0037] One end of the plate 1 along its length is detachably provided with an end positioning block 2. The end positioning block 2 is close to the reference dot hole 11 and perpendicular to the plate 1, forming a right-angled surface that matches the width direction of the pad product 100.

[0038] The plate 1 is detachably provided with a number of side positioning blocks 3 on both sides along the width direction. The number of side positioning blocks 3 are driven linearly to move along the width direction of the plate 1. The side positioning blocks 3 are perpendicular to the plate 1 and form a right angle surface that matches the length direction of the pad product 100.

[0039] When marking dots, place the marking fixture on the upper surface of the pad product 100, with the flat plate 1 in contact with the upper surface of the pad product 100, and the end positioning block 2 in contact with one end face of the pad product 100 in the length direction. Then adjust the side positioning block 3 so that it abuts against and clamps against the two side walls in the width direction of the pad product 100, thereby completing the relative fixation of the marking fixture and the pad product 100.

[0040] Next, dots are made in the reference dot hole 11. Based on the length of the pad product 100, dots are made in a free dot hole 12 at a suitable distance from the reference dot hole 11. Each dot hole can be matched with the dot-making tool to avoid dot-making errors.

[0041] Finally, remove the marking fixture and drill holes according to the marked positions.

[0042] In this embodiment, the lower end of the side wall of the end positioning block 2 near the flat plate 1 is provided with a first inclined surface 21. The first inclined surface 21 gradually slopes from top to bottom away from the flat plate 1. The first inclined surface 21 can play a quick guiding role for the end positioning block 2 when the dotting fixture is placed on the pad. Figure 3 .

[0043] In this embodiment, a second inclined surface 31 is provided at the lower end of the side wall of the side positioning block 3 near the plate 1. This second inclined surface 31 gradually slopes from top to bottom towards the side away from the plate 1, serving as a quick guide for the side positioning block 3. Figure 5 .

[0044] In this embodiment, the end positioning block 2 is detachably connected to the plate 1 by screws.

[0045] In this embodiment, at least one magnet 4 is embedded in the inner wall of the end positioning block 2. The magnet 4 serves as a component for fixing and adsorbing the pad product 100. When the end positioning block 2 is attached to one end of the pad, the magnet 4 is quickly adsorbed and fixed to the pad. On the one hand, it plays the role of quickly installing the positioning and marking fixture, and on the other hand, it can fix the marking fixture to the pad so as to make subsequent marking stable without the need for hand support, which is convenient for single-person marking operation.

[0046] In this embodiment, since the pad products 100 have different specifications and widths, the linear drive includes a long bolt 5 to achieve universality. One end of the long bolt 5 passes through the side positioning block 3 and is threaded into the screw hole 14 on the plate 1. The long bolt 5 is rotatably engaged with the side positioning block 3 via a bearing. By rotating the long bolt 5, the side positioning block 3 can be pressed against the side wall of the pad product 100 to clamp and fix the dotting fixture to the pad product 100. Alternatively, the side positioning block 3 can be moved away from the pad product 100 to disassemble the dotting fixture.

[0047] In this embodiment, the linear drive located on one side of the width direction of the plate 1 further includes an elastic structure 6, which abuts against the bolt cap and the side positioning block 3. The elastic structure 6 includes a spring, which is sleeved on the long bolt 5, and both ends of the spring abut against the bolt cap and the side positioning block 3, respectively. The spring enables elastic clamping, preventing wear on the surface of the pad product 100.

[0048] In this embodiment, the flat plate 1 has grooves 15 on both side walls in the width direction. The grooves 15 serve as guides and positions the side positioning blocks 3. The grooves 15 can guide and position the moving side positioning blocks 3 to ensure their stability and are suitable for clamping pad products 100 of different widths.

[0049] In this embodiment, to prevent wear on the scale value 13, the scale value 13 is a scale groove structure formed on the plate 1, see... Figure 1 .

[0050] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
