Description

Technical Field

[0001] This utility model relates to the field of plastic parts processing, and in particular to a multi-specification positioning card plate for plastic parts size calibration. Background Technology

[0002] In the plastic parts processing, dimensional calibration is a crucial step to ensure that the product meets design standards, directly affecting the assembly performance and reliability of the plastic parts. Currently, plastic parts are showing a trend towards diversification and customization, ranging from micro-electronic component housings to large automotive bumper parts, with a vast size range, from a few millimeters to several meters. Shapes have also expanded from simple flat and cylindrical forms to complex curved surfaces and hollow structures. Positioning calibrators are required for dimensional calibration of plastic parts.

[0003] Existing positioning calibrators are inconvenient for positioning. When placing plastic parts on the calibrator, operators often need to repeatedly adjust the position of the plastic parts to align them with the positioning components. This process is not only time-consuming, but also easily causes surface scratches due to repeated contact with the plastic parts, reducing calibration efficiency. They are also inconvenient to use and cannot be adjusted in size. Generally, the size of the positioning calibrator is fixed and can only position plastic parts of specific sizes. If positioning different sizes is required, the corresponding size positioning calibrator needs to be replaced, which is very troublesome, increases workload, and reduces practicality and applicability. In order to solve the above problems, we propose a multi-size positioning calibrator for plastic part size calibration. Utility Model Content

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multi-specification positioning plate for calibrating the size of plastic parts, including a base plate, a positioning plate bolted to the top of the base plate, two toothed rods slidably sleeved on the inner wall of the positioning plate, and the toothed rods slidably sleeved with the inner wall of the positioning plate, a gear meshing between the two toothed rods, and the gear rotatably connected to the inner wall of the positioning plate, a screw threadedly connected to the inner wall of the positioning plate, and a tension spring provided between one end of the screw and one end of the toothed rod.

[0006] By adopting the above technical solution, pulling the pull block causes the fixing rod to open the clamping plate, pressing the plastic side against the positioning pull plate. Releasing the pull block allows the clamping plate to clamp and position the plastic side. This method facilitates positioning, reduces workload, and improves calibration efficiency. Rotating the adjusting head moves the screw, which changes the tension spring force, thus adjusting the preload of the tension spring, improving stability, and making it convenient to use.

[0007] The present invention is further configured such that: a fixing rod is bolted to the surface of the toothed rod, a sliding rod is slidably sleeved on the inner wall of the fixing rod, a clamping plate is bolted to one end of the sliding rod, a toothed plate is slidably connected to the inner wall of the fixing rod, a bolt is rotatably connected to the surface of the toothed plate, and the bolt is threaded to the inner wall of the fixing rod, and a toothed rack is embedded in the surface of the sliding rod, and the toothed rack meshes with the toothed plate.

[0008] By adopting the above technical solution, the toothed plate is disengaged from the rack by loosening the bolts, the clamping plate is moved to the required position, and then the bolts are tightened to engage the toothed plate with the rack, thus fixing the clamping plate. This method can achieve the purpose of size adjustment, improves practicality and applicability, and makes it convenient to use.

[0009] The present invention is further configured such that an adjusting head is bolted to one end of the screw.

[0010] By adopting the above technical solution, the adjustment head is set to facilitate the rotation of the screw and the adjustment of the clamping force of the clamping plate.

[0011] The present invention is further configured such that a nut is threaded onto the surface of the screw.

[0012] By adopting the above technical solution, the screw is fixed by setting a nut, thereby improving stability.

[0013] The present invention is further configured such that the surfaces of the slide bar and the positioning plate are printed with scale lines.

[0014] By adopting the above technical solution and setting scale lines, it is easy to calibrate the size and adjust the size.

[0015] The present invention is further configured such that a rubber pad is adhered to the surface of the clamping plate.

[0016] By adopting the above technical solution, rubber pads are installed to prevent damage to the plastic parts, while also providing anti-slip properties and improving stability.

[0017] The present invention is further configured such that an anti-detachment head is bolted to one end of the slide rod.

[0018] By adopting the above technical solution and setting an anti-slip head, it is easy to prevent the slide bar from slipping off.

[0019] The present invention is further configured such that a pull block is bolted to one end of the toothed rod located on the left side.

[0020] By adopting the above technical solution, the toothed rod can be moved easily by setting up a pull block.

[0021] In summary, this utility model has the following beneficial effects: 1. This utility model achieves convenient positioning by pulling the pull block to open the clamping plate, pressing the plastic side against the positioning pull plate, and releasing the pull block to clamp and position the clamping plate. This reduces workload and improves calibration efficiency.

This utility model achieves the purpose of size adjustment by loosening the bolts to disengage the toothed plate from the rack, moving the clamping plate to the required position, and then tightening the bolts to engage the toothed plate with the rack, thus fixing the clamping plate. This improves practicality and applicability and makes it convenient to use. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1: refer to Figure 1 and Figure 2 A multi-specification positioning clamp for calibrating the dimensions of plastic parts includes a base plate 1. A positioning clamp 2 is bolted to the top of the base plate 1. Two toothed rods 3 are slidably sleeved on the inner wall of the positioning clamp 2, and gears 4 mesh between the two toothed rods 3. Gears 4 are rotatably connected to the inner wall of the positioning clamp 2. A screw 5 is threadedly connected to the inner wall of the positioning clamp 2. A tension spring 6 is provided between one end of the screw 5 and one end of the toothed rod 3. By pulling the pull block 18, the fixing rod 7 drives the clamping plate 9 to open, pressing the plastic side against the positioning pull plate. Releasing the pull block 18 allows the clamping plate 9 to clamp and position the plastic part. This method facilitates positioning, reduces workload, and improves calibration efficiency. By rotating the adjusting head 13, the screw 5 moves, changing the elasticity of the tension spring 6. This allows adjustment of the preload of the tension spring 6, improving stability and ease of use.

[0026] refer to Figure 1 and Figure 2 One end of the screw 5 is bolted with an adjusting head 13. By setting the adjusting head 13, it is easy to rotate the screw 5 and adjust the clamping force of the clamping plate 9.

[0027] refer to Figure 2 The screw 5 is threaded with a nut 14, which fixes the screw 5 and improves its stability.

[0028] refer to Figure 1 and Figure 2 A pull block 18 is bolted to one end of the left toothed rod 3, which facilitates the movement of the toothed rod 3.

[0029] Example 2: refer to Figure 1 and Figure 3 A fixing rod 7 is bolted to the surface of the toothed rod 3. A sliding rod 8 is slidably sleeved on the inner wall of the fixing rod 7. A clamping plate 9 is bolted to one end of the sliding rod 8. A toothed plate 10 is slidably connected to the inner wall of the fixing rod 7. A bolt 11 is rotatably connected to the surface of the toothed plate 10, and the bolt 11 is threadedly connected to the inner wall of the fixing rod 7. A rack 12 is embedded in the surface of the sliding rod 8, and the rack 12 meshes with the rack 10. By loosening the bolt 11, the rack 10 is disengaged from the rack 12. After moving the clamping plate 9 to the required position, the bolt 11 is tightened, and the rack 12 meshes with the clamping plate 9, thus fixing the clamping plate 9. This method can achieve the purpose of adjusting the size, improves practicality and applicability, and makes it convenient to use.

[0030] refer to Figure 1 The surfaces of the slide bar 8 and the positioning plate 2 are printed with scale lines 15. By setting the scale lines 15, it is easy to calibrate the size and adjust the size.

[0031] refer to Figure 1 and Figure 3 The surface of the clamping plate 9 is bonded with a rubber pad 16. By setting the rubber pad 16, damage to the plastic parts is prevented, and at the same time, it is non-slip and improves stability.

[0032] refer to Figure 1 and Figure 3 One end of the slide rod 8 is bolted with an anti-slip head 17. By setting the anti-slip head 17, it is easy to prevent the slide rod 8 from slipping off.

[0033] Brief description of usage: Pull the lever 18. The movement of lever 18 moves the rack 3, which in turn drives the gear 4 to rotate. The rotation of gear 4 drives the other rack 3 to move, causing the two racks 3 to move in opposite directions. This movement of the racks 3 in opposite directions causes the fixing rod 7 to move in opposite directions. This movement of the fixing rod 7 in opposite directions causes the sliding rod 8 to move in opposite directions. This movement of the sliding rod 8 in opposite directions causes the clamping plate 9 to move in opposite directions, opening the clamping plate 9. Then, press the plastic side against the positioning plate 2. Then, release the lever 18. Under the action of the tension spring, the racks 3 move relative to each other. This relative movement of the racks 3 drives the sliding rod 8 to move relative to each other, which in turn causes the clamping plate 9 to move relative to each other, clamping and positioning the plastic. Then, according to the scale line 15 on the positioning plate 2, the size of the plastic is calibrated to facilitate positioning. By loosening the nut 14 and rotating the adjusting head 13, the screw 5 rotates, which changes the elastic force of the tension spring, thereby changing the clamping force of the clamping plate 9 and thus adjusting the clamping force of the clamping plate 9. Loosening the bolt 11 causes the toothed plate 10 to move and disengage from the rack 12. Then, the sliding rod 8 is moved to move the clamping plate 9 to the required position. After that, the bolt 11 is tightened to make the toothed plate 10 mesh with the rack 12, and the sliding rod 8 is fixed, thereby fixing the clamping plate 9 and completing the adjustment to achieve the purpose of adjusting the size.

[0034] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
