Technical Field
[0001] This utility model relates to the field of plastic parts processing fixtures, specifically a fixing fixture for processing automotive plastic parts. Background Technology
[0002] Automotive plastic parts are an integral part of automobile manufacturing. They are made primarily of plastic through processes such as injection molding and compression molding. They encompass a wide range of components, including interior parts such as dashboards, door panels, and seat backs, as well as exterior parts such as bumpers, rearview mirror housings, and grilles. Automotive plastic parts have many advantages, such as being lightweight, highly designable, low-cost, corrosion-resistant, and having good sound and heat insulation properties. They can not only effectively reduce vehicle weight and improve fuel efficiency or extend the driving range of new energy vehicles, but also create diverse exterior designs for automobiles.
[0003] The processing of automotive plastic parts generally includes selecting suitable plastic raw materials, such as polypropylene; designing and manufacturing corresponding molds based on the shape, size, and precision requirements of the automotive plastic parts; adding preheated plastic raw materials into the barrel of an injection molding machine; melting the raw materials through heating and pressurization; the injection-molded plastic parts usually have some flash and burrs, which need to be processed through trimming and deburring processes; then performing surface treatments such as painting, electroplating, and printing; and finally assembling the processed plastic parts with other automotive components.
[0004] Fixtures are often needed when processing the surface of plastic parts. Existing fixtures require the plastic parts to be removed after one side is processed, and then flipped and clamped again for processing, which is inconvenient. Therefore, a fixture for processing automotive plastic parts is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

By moving the sliding seats on the slide rail, the spacing can be quickly adjusted to adapt to automotive plastic parts of different sizes, improving the fixture's versatility. The rotating seat rotates as a whole, cooperating with the rotating shaft to flip the plastic part in the middle of the fixture, allowing for all-around adjustment of the processing angle to meet the needs of surface treatment, cutting, and other processes, improving processing efficiency, reducing the time spent on repeated clamping, and the fixture, together with the bolts, can fix the automotive plastic part, ensuring that the plastic part will not shift during processing and reducing processing errors caused by the movement of the plastic part.
[0007] Preferably, an air pump is fixedly connected to the top of the support frame; the air pump is located near the cylinder; an air pipe is fixedly connected to the bottom of the air pump; the air pipe extends into the interior of the support frame; an air outlet is fixedly connected to the top of the air pipe; by blowing air through the air pipe and the air outlet, processing debris on the surface of the plastic parts can be removed, reducing debris residue that affects subsequent surface treatment, increasing the cleanliness of the plastic parts surface, and reducing the impact of debris remaining on the surface of automotive plastic parts, which could affect the processing of automotive plastic parts and cause incomplete processing due to contact between automotive plastic parts and debris during processing.
[0008] Preferably, an electric push rod is fixedly connected to the bottom end of the rotating seat; a fixed seat is fixedly connected to the bottom end of the electric push rod; multiple sets of cleaning rods are fixedly connected to the top end of the fixed seat; multiple sets of circular holes are opened at the top end of the rotating seat; the circular holes are evenly distributed on the surface of the rotating seat; the cleaning rods are slidably connected to the circular holes; by pushing the electric push rod to move the fixed seat upward as a whole, the sliding contact between the fixed seat and the circular holes can push out the debris in the circular holes, reducing the failure of debris cleaning caused by debris clogging the circular holes, and increasing the cleanliness of the environment around the processing table.
[0009] Preferably, a first cleaning block is fixedly connected to the top of the cleaning rod; the first cleaning block is slidably connected to the round hole; during the process of ejecting debris from the round hole by the fixing seat, some debris remains inside the round hole due to adhesion, jamming, or other reasons. The first cleaning block is slidably connected to the round hole. When the fixing seat moves the first cleaning block inside the round hole, the first cleaning block can contact and rub against the inner wall of the round hole to clean the remaining debris and the inside of the round hole, increasing the unobstructed flow of the round hole and reducing the blockage of the round hole caused by debris residue.
[0010] Preferably, a baffle is fixed to the side wall of the rotating seat; the baffle is correspondingly arranged with the rotating seat; the baffle on the side wall of the rotating seat can prevent the debris from scattering to the surroundings of the processing table, so that the debris is more concentrated inside the rotating seat and falls from the round hole, reducing the splashing of processing debris.
[0011] Preferably, a collection groove is fixedly connected to the bottom end of the fixed seat; multiple sets of air jets are fixedly connected to the side wall of the electric push rod; the air jets are evenly distributed on the side wall of the electric push rod; by activating the air jets, the debris on the surface of the fixed seat is blown into the collection groove, so that the debris generated from the processing of automotive plastic parts can be collected and processed uniformly.
[0012] The advantages of this utility model are:

After adjusting the distance between the pair of sliding seats 14, the automotive plastic part is placed in the middle of the pair of clamps 16, and the bolt 18 is rotated towards the support frame 11 to clamp the automotive plastic part placed in the middle of the clamp 16. After positioning, the cylinder 12 drives the machining cutter 19 to move downwards, bringing it into contact with the automotive plastic part for processing. During processing, the motor 110 drives the rotating shaft 15 to rotate, turning the automotive plastic part clamped in the middle of the fixture 16. Rotating the rotating base 13 rotates the entire structure above it, adjusting the processing angle of different positions on the automotive plastic part. After processing, the automotive plastic part in the middle of the fixture 16 is removed by rotating the bolt 18, thus completing the machining process. The fixture 16 can be quickly adjusted by moving the sliding seat 14 on the slide rail 17 to accommodate different sizes of automotive plastic parts, thus improving the versatility of the fixture 16. The rotating seat 13 rotates as a whole, and the rotating shaft 15 drives the plastic part in the middle of the fixture 16 to flip over, so that the processing angle can be adjusted in all directions to meet the needs of multiple processes such as surface treatment and cutting, improve processing efficiency, and reduce the time spent on repeated clamping. The fixture 16, together with the bolts 18, can fix the automotive plastic parts to ensure that the plastic parts will not shift during processing and reduce processing errors caused by the shaking of the plastic parts.
[0025] like Figures 1 to 2As shown, an air pump 2 is fixedly connected to the top of the support frame 11; the air pump 2 is located on the side near the cylinder 12; an air pipe 21 is fixedly connected to the bottom of the air pump 2; the air pipe 21 extends into the interior of the support frame 11; an air outlet 22 is fixedly connected to the top of the air pipe 21; during operation, when the processing cutter 19 processes the automotive plastic part held in the middle of the fixture 16, processing debris will be generated. The air pump 2 is started, and air flows out from the air pipe 21 and blows out from the air outlet 22, blowing the debris generated during the processing of the automotive plastic part onto the surface of the rotating seat 13; by blowing air out through the air pipe 21 and the air outlet 22, the processing debris on the surface of the plastic part can be removed, reducing debris residue, which affects subsequent surface treatment, increasing the cleanliness of the plastic part surface, and reducing the impact of debris remaining on the surface of the automotive plastic part, which affects the processing of the automotive plastic part, causing the automotive plastic part to come into contact with debris during processing, resulting in incomplete processing.
[0026] like Figures 1 to 2 As shown, an electric push rod 3 is fixedly connected to the bottom end of the rotating seat 13; a fixed seat 31 is fixedly connected to the bottom end of the electric push rod 3; multiple sets of cleaning rods 32 are fixedly connected to the top end of the fixed seat 31; multiple sets of circular holes 33 are opened at the top end of the rotating seat 13; the circular holes 33 are evenly distributed on the surface of the rotating seat 13; the cleaning rods 32 are slidably connected to the circular holes 33; during operation, the air outlet 22 blows the debris generated from the processing of automotive plastic parts onto the surface of the rotating seat 13, and the debris falls into the middle of the circular holes 33 and exits from the circular holes 33. The surface falls onto the surface of the fixed base 31. Debris has been trapped inside the round hole 33 for a long time, causing blockage. Pushing the electric push rod 3 moves the fixed base 31 upward as a whole. The fixed base 31 and the round hole 33 slide into contact, pushing out the debris on the surface of the round hole 33. By pushing the electric push rod 3 to move the fixed base 31 upward as a whole, the sliding contact between the fixed base 31 and the round hole 33 can push out the debris in the round hole 33, reducing the failure of debris cleaning caused by debris blockage in the round hole 33, and increasing the cleanliness of the environment around the processing table 1.
[0027] like Figure 2 and Figure 4 As shown, a first cleaning block 4 is fixedly connected to the top of the cleaning rod 32; the first cleaning block 4 is slidably connected to the round hole 33; during operation, when the fixed seat 31 pushes out the debris inside the round hole 33, the first cleaning block 4 can contact and rub the relatively stubborn debris remaining inside the round hole 33 to clean the debris inside the round hole 33; during the process of the fixed seat 31 pushing out the debris inside the round hole 33, some debris remains inside the round hole 33 due to adhesion, jamming, etc. The first cleaning block 4 is slidably connected to the round hole 33. When the fixed seat 31 drives the first cleaning block 4 to move inside the round hole 33, the first cleaning block 4 can contact and rub against the inner wall of the round hole 33 to clean the remaining debris and the inside of the round hole 33, increase the unobstructed flow of the round hole 33, and reduce the blockage of the round hole 33 caused by debris residue.
[0028] like Figure 1and Figure 3 As shown, a baffle 5 is fixedly connected to the side wall of the rotating seat 13; the baffle 5 is correspondingly arranged with the rotating seat 13; during operation, when the air outlet 22 blows the processing debris of the automotive plastic parts onto the surface of the rotating seat 13, the baffle 5 can prevent the debris from staying on the surface of the rotating seat 13, so that the debris on the surface of the rotating seat 13 accumulates; through the baffle 5 on the side wall of the rotating seat 13, the debris can be prevented from scattering to the sides of the processing table 1, so that the debris is more concentrated inside the rotating seat 13 and falls from the round hole 33, reducing the splashing of processing debris.
[0029] like Figure 1 and Figure 5 As shown, a collection groove 6 is fixedly connected to the bottom end of the fixed base 31; multiple sets of air jets 61 are fixedly connected to the side wall of the electric push rod 3; the air jets 61 are evenly distributed on the side wall of the electric push rod 3; during operation, after the debris falling into the round hole 33 lands on the surface of the fixed base 31, the multiple sets of air jets 61 are activated to blow the debris remaining on the surface of the fixed base 31 into the collection groove 6, so that the debris generated during the processing of automotive plastic parts can be uniformly processed; by activating the air jets 61, the debris on the surface of the fixed base 31 is blown into the collection groove 6, so that the debris generated during the processing of automotive plastic parts can be uniformly collected and processed.
[0030] Working principle: A pair of sliding seats 14 are moved above the slide rail 17 to adjust the distance between them for clamping different automotive plastic parts. After adjusting the distance, the automotive plastic part is placed in the middle of a pair of clamps 16. The bolt 18 is rotated towards the support frame 11 to clamp the automotive plastic part placed in the middle of the clamps 16. After the automotive plastic part in the middle of the clamps 16 is clamped and fixed, the cylinder 12 is pushed to move the machining cutter 19 downwards. The machining cutter 19 contacts the automotive plastic part, thus machining the part. During processing, the motor 110 is started to drive the rotating shaft 15 to rotate, turning and flipping the automotive plastic part clamped in the middle of the fixture 16. Rotating the rotating base 13 rotates the entire structure above it, adjusting the processing angle of different positions on the automotive plastic part. After processing, the automotive plastic part is removed from the fixture 16 by rotating the bolt 18, thus completing the processing. When the processing tool 19 processes the automotive plastic part clamped in the middle of the fixture 16, it generates processing debris. The air pump 2 is started to draw air from the air pipe 21. Air flows out from the air outlet 22, blowing away the debris generated during the processing of the automotive plastic parts onto the surface of the rotating seat 13. After the debris is blown onto the surface of the rotating seat 13, it falls into the middle of the round hole 33 and then onto the surface of the fixed seat 31. The debris accumulates inside the round hole 33 over time, causing blockage. The electric push rod 3 is then pushed to move the fixed seat 31 upwards, causing it to slide into contact with the round hole 33, pushing out the debris from the surface of the round hole 33. The fixed seat 31 then pushes out the debris from inside the round hole 33. When the air outlet 22 blows the processing debris of the automotive plastic parts onto the surface of the rotating seat 13, the baffle 5 can prevent the debris from staying on the surface of the rotating seat 13, so that the debris on the surface of the rotating seat 13 can be collected. After the debris falling into the round hole 33 lands on the surface of the fixed seat 31, multiple sets of air jets 61 are activated to blow the debris staying on the surface of the fixed seat 31 into the collection tank 6, so that the debris during the processing of automotive plastic parts can be uniformly processed.
[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
