Description

Technical Field

[0001] The utility model relates to the technical field of plastic product processing, in particular to a positioning device used for plastic product processing. Background Art

[0002] Plastic products are a general term for daily and industrial products made of plastic as the main raw material. They include products made from injection molding, vacuum forming and other processes using plastic as the raw material. Plastic is a type of synthetic polymer material with plasticity. Specifically, plastic is a material that uses natural or synthetic resin as the main component and adds various additives. It can be molded into a certain shape under certain temperature and pressure conditions and maintains the same shape at room temperature. In the processing of plastic products, positioning devices are indispensable.

[0003] In the prior art, when positioning plastic parts before processing, the plastic parts need to be fixed on a placement table and clamped before processing operations can be performed. After being fixed, the plastic parts generally cannot be flipped and adjusted, which makes it inconvenient to process multiple surfaces of the plastic parts. After the single-side processing of the plastic parts is completed, they need to be unfastened and turned over, and then fixed again before processing of other surfaces can be performed. The operation is time-consuming and labor-intensive. Secondly, plastic parts have different shapes. General positioning devices only clamp and fix them through two clamps, which is difficult to adapt to plastic parts of different shapes for clamping and positioning, and the stability is not high. For this reason, we propose a positioning device for plastic product processing to solve the above problems. Utility Model Content

[0039] The positioning assembly includes: two limit blocks 11 and two limit rods 13. The limit blocks 11 are fixedly mounted on the corresponding rotating shafts 6. A plurality of limit grooves 12 are provided on the limit blocks 11. The bottom ends of the two limit rods 13 are welded to the top of the processing table 1, and the top ends of the limit rods 13 can be detached and inserted into the corresponding limit grooves 12.

[0040] By means of the above structure: by starting the motor 4, the first screw rod 5 can be driven to rotate, and then the threaded connection between the first screw rod 5 and the U-shaped frame 3 can be used to drive the two rotating shafts 6, the two limit blocks 11 and the positioning assembly to adjust the height. Here, when the limit block 11 moves upward, the limit rod 13 can be disengaged from the insertion between the corresponding limit groove 12, and the flipping restriction of the positioning assembly and the two rotating shafts 6 can be released. At this time, the positioning assembly is flipped by rotating the positioning assembly. Similarly, the plastic part clamped and fixed inside the positioning assembly can be flipped, so that it is convenient to process different surfaces of the plastic part. In addition, after the plastic part is flipped, the limit block 11 can be driven to move downward through the reverse rotation of the motor 4 and the reverse transmission cooperation with the positioning assembly, so that the top end of the limit rod 13 can be inserted into the corresponding limit groove 12, and the plug-in limit cooperation between the limit rod 13 and the limit groove 12 can limit the flipping of the rotating shaft 6, the positioning assembly and the plastic part, thereby realizing the positioning and fixing of the plastic part after flipping.

[0041] As a preferred solution of the utility model, a support block 2 is welded on the top of the processing table 1. By providing the support block 2, the plastic part can be stably supported, and the stability of the plastic part during processing can be guaranteed.

[0042] As a preferred solution of the utility model, a turntable 14 is welded to the left end of the rotating shaft 6 on the left side. The turntable 14 can be easily operated by a person to drive the positioning assembly and the plastic part to flip.

[0043] As a preferred solution of the utility model, the clamping assembly includes a frame 7 and a plurality of second screw rods 8. The left and right sides of the frame 7 are respectively welded to the ends of the two rotating shafts 6 that are close to each other. One end of the second screw rod 8 passes through one side of the frame 7 and extends to the interior of the frame 7. The plurality of second screw rods 8 are all threadedly connected to the frame 7. By rotating the plurality of second screw rods 8 in sequence and cooperating through the threaded connection between the second screw rods 8 and the frame 7, the clamping depth of the second screw rods 8 can be adjusted as needed, and the plastic parts can be stably clamped at multiple positions according to the shape of the plastic parts, thereby improving the clamping stability of special-shaped plastic parts and facilitating personnel to perform processing operations on plastic parts.

[0044] As a preferred solution of the utility model, a plurality of threaded holes 10 are provided on the inner wall of the frame 7, and one end of the second screw rod 8 passes through the corresponding threaded hole 10 and is threadedly connected to the threaded hole 10.

[0045] As a preferred solution of the utility model, an anti-skid pad 9 is fixedly mounted on one end of the second screw rod 8. The anti-skid pad 9 can improve the clamping stability of the plastic part.

[0046] It should be noted that the specific type of motor 4 to be used is selected by the relevant technical personnel familiar with the field, and the above motor 4 belongs to the existing technology and will not be elaborated in this solution.

[0047] The working principle of the utility model is as follows: when in use, first connect the device to an external power source, and then place the plastic part on the top of the support block 2. Here, by rotating multiple second screw rods 8 in sequence and cooperating through the threaded connection between the second screw rods 8 and the frame 7, the clamping depth of the second screw rods 8 can be adjusted as needed, and multiple positions of the plastic part can be stably clamped according to the shape of the plastic part, thereby improving the clamping stability of special-shaped plastic parts and facilitating personnel to perform processing operations on the plastic parts. When the plastic parts are clamped, the plastic parts can be processed. In addition, by starting the motor 4, the first screw rod 5 can be driven to rotate, and then through the threaded connection between the first screw rod 5 and the U-shaped frame 3, the two rotating shafts 6, the two limit blocks 11 and the positioning assembly can be driven to adjust the height. Here, when the limit block 11 moves upward, the limit rod 13 can be disengaged from the corresponding limit groove 12. By plugging in, the flipping restriction of the positioning assembly and the two rotating shafts 6 can be released. At this time, the two rotating shafts 6 and the positioning assembly can be driven to flip by rotating the turntable 14. Similarly, the plastic parts clamped and fixed inside the positioning assembly can be flipped, so that it is convenient to process different surfaces of the plastic parts. In addition, after the plastic parts are flipped, the reverse rotation of the motor 4 and the reverse transmission cooperation between the positioning assembly can drive the plastic parts to move downward and contact between the support block 2. Here, the support block 2 can stably support the plastic parts and ensure the stability of the plastic parts during processing. At the same time, when the limit block 11 moves downward, the limit rod 13 can be plugged into the corresponding limit groove 12. Through the plug-in and limit cooperation between the limit rod 13 and the limit groove 12, the flipping of the rotating shaft 6, the positioning assembly and the plastic parts can be limited, thereby realizing the positioning and fixation of the plastic parts after flipping.
