Description

Technical Field

[0001] This utility model relates to the field of forklift technology, and in particular to a forklift oil filter cover positioning clamp. Background Technology

[0002] The oil filter cover is a non-shaft casting, and its left inner hole can be easily and quickly machined by turning. However, the oil filter cover is an irregularly shaped part, and the center of rotation of the inner hole does not coincide with the center of the workpiece. The standard chuck of the existing CNC horizontal lathe has a clamping surface that does not coincide with the center of the irregular workpiece, resulting in clamping eccentricity and making it difficult to meet the required machining accuracy. This also makes the oil filter cover unmachinable on a horizontal CNC lathe. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide a forklift oil filter cover positioning fixture that eliminates the need for complex adjustments and alignment operations, significantly reducing auxiliary processing time.

[0004] The forklift oil filter cover positioning fixture proposed in this utility model includes a base, a bracket fixed to the top of the base, an oil filter cover fixed to one end of the bracket, and cylindrical pins and diamond pins fixed diagonally on the bracket for positioning the oil filter cover. Fixing components are fixed diagonally on the other side of the bracket. A through-insertion screw is provided at one end of the oil filter cover, and the bottom end of the screw is threadedly connected to the fixing components.

[0005] Preferably, the support includes a base plate, a positioning plate is fixed at the top center of the base plate, and stiffening plates that abut against the positioning plate are fixed at both the left and right ends of the base plate.

[0006] Preferably, the positioning plate has mounting holes at opposite corners, and mounting grooves for placing the fixing components are formed at opposite corners opposite to the mounting holes.

[0007] Preferably, the fixing assembly includes a fixing plate, a bushing that is threadedly connected to the screw is fixed at the top center of the fixing plate, and threaded holes are provided at both the left and right ends of the fixing plate for fixing to the positioning plate by screws.

[0008] Preferably, the oil filter cover has a positioning hole on its opposite corner that mates with the diamond-shaped pin and the cylindrical pin, and a fixing hole on the opposite corner of the oil filter cover that mates with the screw.

[0009] Preferably, a balance block is fixed to the top of the base away from the positioning plate. The balance block is used to ensure that the center of gravity of the tooling coincides with the rotation center during processing, so as to avoid the displacement of the hole center position caused by eccentric rotation during processing.

[0010] The beneficial effects of this invention are as follows: The bracket, diamond-shaped pins, and cylindrical pins precisely engage with the positioning holes on the oil filter cover, achieving high-precision workpiece positioning. This positioning method effectively eliminates positional deviations during processing, ensuring the inner hole machining accuracy of the oil filter cover meets design requirements. Simultaneously, the connection of the fixing components and screws ensures stability while facilitating assembly and disassembly. In practical use, operators can quickly clamp and position the oil filter cover without complex adjustments and alignment operations, significantly reducing auxiliary processing time. Furthermore, the simple fixture structure and low failure rate reduce equipment maintenance and repair time and costs. Attached Figure Description

[0018] Reference Figure 1-6The forklift oil filter cover positioning fixture includes a base 1, which is clamped by a horizontal CNC lathe chuck, connecting the fixture to the lathe. The connection between the base 1 and the lathe chuck enables quick docking of the fixture and the lathe, further improving processing efficiency. At this point, the center of the base 1 is coaxial with the spindle of the horizontal lathe. A bracket 2 is threaded to the top of the base 1, and an oil filter cover 7 is fixed to one end of the bracket 2. The pre-machined lower surface of the oil filter cover 7 rests on the bracket 2. A pair of oil filter covers are fixed diagonally on the bracket 2. The filter cover 7 is positioned by cylindrical pins 5 and diamond pins 4, with the cover 7 engaging with both pins 4 and 5 for positioning. This completes the positioning of the filter cover 7. On the other side of the bracket 2, fixing components 204 are fixed diagonally. One end of the filter cover 7 has a through-hole screw 6, with the bottom end of the screw 6 threadedly connected to the fixing component 204. The screw 6 passes through the filter cover 7, and by rotating it, the screw 6 is connected to the fixing component 204, thus fixing the filter cover 7. At this point, the inner hole to be machined in the filter cover 7 is coaxial with the base 1 and also with the spindle of the horizontal lathe.

[0019] The cylindrical pin 5 is for positioning, and the diamond pin 4 is for orientation. They are used to limit the angular rotational freedom and also to prevent over-positioning.

[0020] Each component, such as base 1, bracket 2, balance block 3, diamond pin 4, and cylindrical pin 5, is designed and assembled independently. This modular structure allows for standardized production of each component during manufacturing, facilitating quality control and mass production. The modular design also demonstrates significant advantages in subsequent use and maintenance. When a component becomes worn or damaged, the corresponding module can be quickly located and replaced without extensive disassembly and repair of the entire fixture, greatly reducing equipment downtime and improving production efficiency.

[0021] The bracket 2 includes a base plate 201, a positioning plate 202 is threadedly connected to the top center of the base plate 201, and rib plates 203 that abut against the positioning plate 202 are threadedly connected to both the left and right ends of the base plate 201. The rib plates 203 are used to support the positioning plate 202. The base plate 201, the positioning plate 202 and the rib plates 203 are connected to support the fixing of the oil filter cover 7. At the same time, the bracket 2 has a simple structure and is practical.

[0022] The positioning plate 202 has mounting holes 205 on both sides, which facilitate the installation of the diamond pin 4 and the cylindrical pin 5. The positioning plate 202 has mounting grooves 206 on the opposite side of the mounting holes 205 for placing the fixing component 204, which facilitates the fixing component 204 to be fixed on the surface of the positioning plate 202.

[0023] The fixing assembly 204 includes a fixing plate 207. A bushing 208 that is threadedly connected to a screw 6 is fixed to the top center of the fixing plate 207. Threaded holes 209 are provided at both ends of the fixing plate 207 for fixing to the positioning plate 202 by screws 6. The fixing plate 207 can be fixed to the positioning plate 202. The bushing 208 is inserted into the interior of the positioning plate 202 and threadedly connected to the bushing 208 by screws 6 for fixing the oil filter cover 7 to the positioning plate 202.

[0024] The connection using standard components such as fixing component 204 and screws 6 ensures both stability and ease of assembly and disassembly. In actual use, operators can quickly clamp and position the oil filter cover 7 without complex adjustments or alignment, significantly reducing auxiliary processing time. Furthermore, the simple structure and low failure rate of fixing component 204 and screws 6 reduce equipment maintenance and repair time and costs.

[0025] The oil filter cover 7 has a positioning hole 12 on its diagonal side that mates with the diamond pin 4 and the cylindrical pin 5. The oil filter cover 7 also has a fixing hole 13 on its opposite diagonal side that mates with the screw 6. The positioning hole 12 and the fixing hole 13, together with the diamond pin 4, the cylindrical pin 5 and the screw 6, complete the positioning and fixing of the oil filter cover 7.

[0026] The diamond-shaped pin 4 and the cylindrical pin 5 work together precisely with the positioning hole 12 on the oil filter cover 7, achieving high-precision positioning of the workpiece. This positioning method effectively eliminates positional deviations of the workpiece during processing, ensuring that the machining accuracy of the inner hole of the oil filter cover 7 meets the design requirements.

[0027] The top of the base 1 is threaded with a balance block 3 that is far away from the bracket 2. The balance block 3 is used to ensure that the center of gravity of the tooling coincides with the rotation center during machining, so as to avoid the hole center position shift caused by eccentric rotation during machining.

[0028] In use, the base 1 is clamped by the chuck of a horizontal CNC lathe, connecting the tooling to the lathe. At this point, the center of the base 1 is coaxial with the spindle of the horizontal lathe. The machined lower surface of the oil filter cover 7 is placed on the bracket 2, and the two positioning holes 12 on the oil filter cover 7 are respectively engaged with the diamond pin 4 and the cylindrical pin 5 for positioning. The diamond pin 4 and the cylindrical pin 5 are inserted into the positioning holes 12, thus positioning the oil filter cover 7. Then, a screw 6 passes through the other two fixing holes 13 on the workpiece, bringing the screw 6 into contact with the bushing 208. Rotating the screw 6 then threads the screw 6 into the bushing 208. As the screw 6 is continuously rotated, its rear end presses against the oil filter cover 7, connecting the oil filter cover 7 to the bracket 2, thus fixing the oil filter cover 7 to the bracket 2. At this point, the inner hole to be machined in the oil filter cover 7 is coaxial with the base 1, i.e., coaxial with the spindle of the horizontal lathe.
