Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, specifically a novel forklift mounting plate drilling fixture. Background Technology

[0002] Forklift mounting plates involve a drilling process. Currently, due to efficiency and cost considerations, plasma cutting is used instead of laser cutting for drilling these plates. However, plasma cutting has lower precision, making it impossible to guarantee the required hole dimensions. Therefore, after stamping, drilling is performed at a machining center. Furthermore, because the stamped mounting plate has an irregular shape, general-purpose fixtures cannot guarantee accurate positioning, making processing difficult. Utility Model Content

[0003] The purpose of this invention is to provide a fixture that can improve the machining efficiency of holes in forklift mounting plates and ensure the accuracy of hole gaps. The fixture is also suitable for CNC machine tool machining, thus solving the above-mentioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A novel CNC drilling fixture for forklift mounting plates includes a rectangular base plate mounted on a CNC machine tool processing platform. Pads are provided at each of the four corners of the base plate to ensure the bottom of the base plate is not obstructed during drilling. Several limiting plates are evenly distributed on the top of the base plate, with a double-ended screw inserted into the center of each limiting plate. Nuts are screwed to both ends of the double-ended screw, and baffles are fitted onto both ends of the double-ended screw. The baffles are located between the nuts and the limiting plates, and cooperate with the limiting plates to clamp the workpiece to be processed. A positioning component is provided on the base plate between the baffles and the limiting plates for positioning the workpiece. Several clearance holes are evenly distributed on the base plate, corresponding to the holes to be processed on the clamped workpiece.

[0006] Preferably, the positioning component includes a guide post mounted on the base plate by screws, a centering block fitted on the guide post to fit the inner shape of the workpiece, and a spring fitted on the outer side of the guide post to prevent the centering block from falling off due to gravity.

[0007] Preferably, a groove is provided in the middle of the bottom of the dividing block to avoid interference with the double-ended screw when the dividing block is pressed down.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting multiple limiting plates and using a screw and nut assembly to cooperate with the setting of baffles, this utility model can clamp multiple forklift mounting plates at one time. At the same time, it is equipped with a positioning structure to position the forklift mounting plates, which effectively improves the processing efficiency of the holes of the forklift mounting plates and the accuracy of the hole gaps.

[0014] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] like Figures 1 to 3 As shown, this embodiment of the utility model includes a rectangular base plate 1 installed on a CNC machine tool processing platform. Pads 2 are provided at the four corners of the bottom of the base plate 1 to ensure the bottom of the base plate 1 is not obstructed during drilling operations. Four limiting plates 4 are evenly distributed on the top of the base plate 1. A double-ended screw 6 is inserted into the middle of each limiting plate 4, and nuts 7 are screwed to both ends of the double-ended screw 6. Baffles 5 are sleeved on both ends of the double-ended screw 6, located between the nuts 7 and the limiting plates 4. The baffles 5 and the limiting plates 4 cooperate to clamp the workpiece 11 to be processed. A positioning component is provided on the base plate 1 between the baffles 5 and the limiting plates 4 for positioning the workpiece 11 to be processed. Several clearance holes 8 are evenly distributed on the base plate 1, corresponding to the holes 1101 to be processed on the clamped workpiece 11.

[0017] Preferably, the positioning component includes a guide post 9 that is screwed onto the base plate 1, a centering block 3 that fits the inner shape of the workpiece 11 being processed is sleeved on the guide post 9, and a spring 10 is sleeved on the outside of the guide post 9 to prevent the centering block 3 from falling due to gravity. A groove is provided in the middle of the bottom of the centering block 3 to prevent the centering block 3 from interfering with the double-ended screw 6 when it is pressed down.

[0018] like Figure 4 As shown, the workpiece 11 to be processed is placed between the baffle 5 and the limiting plate 4, and its interior is in contact with the centering block 3. This is used to position it so that the holes 1101 to be processed at both ends correspond to the clearance holes 8. After it is placed, tighten the nut 7 so that the baffle 5 and the limiting plate 4 cooperate to clamp the workpiece 11 to be processed, and thus drilling can be performed.
