[0017] This invention provides a positioning fixture for a machine tool used in the processing of automotive parts. It has the following advantages:

[0018] 1. This positioning fixture for automotive parts processing machine tools, through the setting of a receiving mechanism, addresses the issue of parts easily falling off during processing. Since parts vary in size, large parts are caught at the clamping plate after falling, making them easy to retrieve. Small parts, however, are more likely to have dust on their outer surface after falling; therefore, they are cleaned and stored for easy handling. This achieves the purpose of facilitating the receiving of parts and cleaning small-sized components.

[0019] 2. This positioning fixture for automotive parts processing machine tools, through the setting of a clamping mechanism, addresses the difficulty of adjusting the angle and height of parts during the clamping process. When changing the processing position, it is necessary to manually re-clamp the parts. Therefore, the fixture in the equipment can be raised, lowered, and rotated, facilitating processing. This achieves the purpose of easily fixing parts and easily adjusting the processing direction.

[0020] 3. The positioning fixture for this automotive parts processing machine tool, by setting up a positioning mechanism, requires manual movement and re-fixing of the fixture when changing its position, which is time-consuming and labor-intensive. Furthermore, parts are prone to falling off when the fixture position is changed. Therefore, a positioning mechanism is set up to drive the movement of the clamping mechanism and the cooling mechanism, making the equipment operate more smoothly and facilitating operation when moving the fixture. This achieves the goal of controlling the position of the clamping mechanism and the cooling mechanism and maintaining a stable state.

[0021] 4. This positioning fixture for automotive parts processing machine tools, by incorporating a cooling mechanism, allows parts with high surface temperatures to be moved into the cooling mechanism for cooling after machining. Simultaneously, the dimensions of the parts can be checked for compliance by adjusting the length of the second adjusting rod inside the cooling mechanism. This achieves the goals of facilitating faster cooling of the parts and protecting them. Attached Figure Description

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0032] like Figures 1-8 As shown, the present invention provides a technical solution, specifically including:

[0033] Machine tool 1 has a stable electric telescopic column and a slide 4 opened inside the machine tool 1. The machine tool 1 is provided with a receiving electric telescopic column 2. The machine tool 1 is fixedly connected with a receiving mechanism 3. The slide 4 is slidably connected with a cooling mechanism 7.

[0034] The clamping mechanism 5 is used to clamp and fix the parts and control the height of the parts. The clamping mechanism 5 includes a sliding column 501 and an adjusting component 508. A bearing 502 is fixedly connected above the sliding column 501. A fixed column 503 is rotatably connected inside the bearing 502. The adjusting component 508 is rotatably connected inside the fixed column 503. The sliding column 501 is slidably connected inside the slide groove 4.

[0035] The positioning mechanism 6 is used to control the position of the clamping mechanism 5 in the slide 4. The positioning mechanism 6 includes an electric telescopic column 601 and a reinforcing plate 604. A fan box 602 is fixedly connected to the top of the electric telescopic column 601. An electric telescopic rod 603 is fixedly connected to the outside of the fan box 602. The electric telescopic column 601 is fixedly connected to the top of the machine tool 1. The reinforcing plate 604 is fixedly connected to the outside of the electric telescopic rod 603.

[0036] The electric telescopic column 2 has a flow hole inside, and the machine tool 1 has a water tank fixedly connected inside, as well as a connecting groove 8 inside. This design facilitates the fixing and repositioning of parts while protecting them. Before using the equipment, the parts are manually placed inside the clamping mechanism 5 according to their processing position, and the positioning mechanism 6 is activated to adjust the position of the clamping mechanism 5. After processing, the parts can be transferred to the cooling mechanism 7, and the positioning mechanism 6 is activated again to adjust the position of the cooling mechanism 7. If a part falls during operation, the receiving mechanism 3 can be activated for simple cleaning and catching.

[0037] A magnetic shell is fitted around the sliding column 501. A top plate 504 is fixedly connected to the top of the fixed column 503. A second sliding groove is opened inside the fixed column 503. A second electric telescopic rod 505 is fixedly connected inside the second sliding groove. A sliding plate 506 is fixedly connected above the second electric telescopic rod 505. A second bearing 507 is fixedly connected to the outside of the sliding plate 506. The second bearing 507 is rotatably connected to the adjusting component 508.

[0038] The adjusting assembly 508 includes an adjusting rod 5081, a fixing block 5082 is fixedly connected to the outside of the adjusting rod 5081, a rubber plate 5083 is fixedly connected to the outside of the fixing block 5082, and the adjusting rod 5081 is rotatably connected inside the second bearing 507.

[0039] A spring 5084 is externally fixed to the fixing block 5082, and an angle plate 5085 is externally fixed to the spring 5084. The angle plate 5085 has a locking hole 5086 inside, and a locking post is externally fixed to the angle plate 5085. The locking hole 5086 engages with the locking post. This design has the advantages of facilitating the fixing of parts and adjusting the machining direction. Manually pulling the angle plate 5085 to the left and right sides causes the angle plate 5085 to move the spring 5084 outwards. The part is then manually placed between the left and right angle plates 5085. The spring 5084 gradually returns to its original position. The length of the adjusting rod 5081 is then manually adjusted to engage the locking hole 5086 with the locking post.

[0040] Before processing, the length of the adjusting rod 5081 and the on / off state of the second electric telescopic rod 505 can be adjusted according to the designated position. When processing in other directions is required, the adjusting rod 5081 can be manually rotated to change the processing direction.

[0041] An adjusting column 605 is fixedly connected to the outside of the reinforcing plate 604, and a magnetic ring 606 is fixedly connected to the outside of the adjusting column 605. Several air outlets are opened at one end of the fan box 602 near the reinforcing plate 604. This design has the advantage of facilitating the control of the clamping mechanism and cooling mechanism while maintaining a stable state. Depending on the position of the sliding column 501, the length of the adjusting column 605 is manually adjusted, and the electric telescopic column 601 is activated. At this time, the electric telescopic column 601 begins to drive the upper fan box 602 upward. When the magnetic ring 606 is directly above the sliding column 501, the electric telescopic column 601 is closed, and the magnetic ring 606 is attracted and fixed to the magnetic outer shell of the sliding column 501. At this time, the position of the magnetic ring 606 can be controlled by opening the electric telescopic rod 603, thereby adjusting the position of the sliding column 501.

[0042] The receiving mechanism 3 includes an electric push rod 301, a second adjusting column 302 is fixedly connected to the outside of the electric push rod 301, a spring rod 303 is fixedly connected to the outside of the second adjusting column 302, and the electric push rod 301 is fixedly connected to the outside of the machine tool 1.

[0043] The spring rod 303 is externally fixedly connected to a backing plate 307, the backing plate 307 is externally fixedly connected to a locking plate 308, and the locking plate 308 is internally fixedly connected to a center rod 309.

[0044] The machine tool 1 has an inclined groove 304 inside, and a spray pipe 306 is fixedly connected to the bottom of the water tank. The machine tool 1 also has a flow port 305 inside. This design facilitates the receiving of parts and the cleaning of small parts. When a part falls from above, it moves downwards to the inclined groove 304. At this point, the part begins to press outwards against the retaining plate 308. Small parts can move downwards directly through the gap between the retaining plates 308, allowing the spray pipe 306 to be opened for cleaning. After cleaning, the parts can be removed through the connecting groove 8. Larger parts press against the retaining plate 308, which in turn presses against the spring rod 303, locking the part between the retaining plate 308 and the inclined groove 304 for easy removal.

[0045] The cooling mechanism 7 includes a second sliding column 701, a base plate 702 is fixedly connected to the outside of the second sliding column 701, a fan is fixedly connected to the inside of the base plate 702, a ventilation channel 703 is opened inside the base plate 702, and the second sliding column 701 is slidably connected to the inside of the slide groove 4.

[0046] An arc-shaped plate 704 is fixedly connected to the outside of the base plate 702. A vertical plate 705 is fixedly connected above the arc-shaped plate 704. A surrounding plate 706 is rotatably connected to the outside of the arc-shaped plate 704. A second adjusting rod is fixedly connected inside the surrounding plate 706. This design facilitates faster cooling of the parts and protects them. After processing, the parts can be manually placed on top of the base plate 702, with the arc-shaped plate 704 positioned on the left and right sides of the parts. The fan is then turned on, and the air from the fan moves upward through the ventilation channel 703, aiding in heat dissipation. Simultaneously, the surrounding plates 706 on the left and right sides of the parts provide protection. Before placing the parts, the length of the second adjusting rod can be manually adjusted according to the required dimensions of the parts to check if they can be placed smoothly and to determine if the dimensions of the parts are acceptable.

[0047] Working Principle: Before using the equipment, manually place the part inside the clamping mechanism 5 according to its processing position. Manually pull the angle plates 5085 to the left and right sides. At this time, the angle plates 5085 drive the springs 5084 to move outward. Manually place the part between the angle plates 5085 on the left and right sides. The springs 5084 gradually return to their original position. Manually adjust the length of the adjusting rod 5081 so that the locking hole 5086 engages with the locking post. Before processing, the length of the adjusting rod 5081 and the on / off state of the second electric telescopic rod 505 can be adjusted according to the specified position. When processing in other directions is required, the adjusting rod 5081 can be manually rotated to change the processing direction. Then activate the positioning mechanism 6, manually adjust the length of the adjusting column 605 according to the position of the sliding column 501, and activate the electric telescopic column 601. At this time, the electric telescopic column 601 starts to drive the upper fan box 602 to move upward. When the magnetic ring 606 is directly above the sliding column 501, close the electric telescopic column 601. The magnetic ring 606 is attracted and fixed to the magnetic shell outside the sliding column 501. At this time, the position of the magnetic ring 606 can be controlled by activating the electric telescopic rod 603, thereby adjusting the position of the sliding column 501.

[0048] After processing, the parts can be transferred to the cooling mechanism 7. After processing, the parts can be manually placed on top of the base plate 702, with the arc-shaped plate 704 positioned on either side of the parts. The fan is then turned on, and the airflow from the fan moves upward through the ventilation channel 703, assisting in heat dissipation. Simultaneously, the surrounding plates 706 on either side of the parts provide protection. Before placing the parts, the length of the second adjusting rod can be manually adjusted according to the required dimensions to check if the parts can be placed smoothly and to confirm that the dimensions are acceptable. Similarly, the positioning mechanism 6 is activated to adjust the position of the cooling mechanism 7. Based on the position of the second sliding column 701, manually adjust the length of the adjusting column 605 and open the electric telescopic column 601. At this time, the electric telescopic column 601 starts to drive the upper fan box 602 to move upward. When the magnetic ring 606 is directly above the sliding column 501, close the electric telescopic column 601. The magnetic ring 606 is attracted and fixed to the magnetic shell outside the second sliding column 701. At this time, the position of the magnetic ring 606 can be controlled by opening the electric telescopic rod 603, thereby adjusting the position of the second sliding column 701.

[0049] During operation, if a part falls, the receiving mechanism 3 can be activated. When the part falls from above, it will move downwards to the inclined groove 304. At this point, the part begins to press outwards against the retaining plate 308. Small parts can move downwards directly through the gap between the retaining plates 308. The spray nozzle 306 can be activated to clean the small parts, which can then be removed through the connecting groove 8. Larger parts press against the retaining plate 308, which in turn presses against the spring rod 303, locking the part between the retaining plate 308 and the inclined groove 304 for easy removal.
