[0002] The anti-deformation clamping fixture for thin-walled deep-drawn parts is a specialized clamping system designed to prevent deformation during the machining or inspection of such parts. Thin-walled deep-drawn parts typically have very thin walls, and common clamps often employ external clamping, holding the parts from the outside. However, this clamping process can easily cause the thin-walled deep-drawn parts to deform under pressure. Utility Model Content

A clamping plate is slidably connected to the inner wall of the through grooves. A trapezoidal block is fixedly connected to one side of the clamping plate. The outer side of the trapezoidal block is slidably connected to the inner wall of the through groove. A spring is fixedly connected to the top of the trapezoidal block. One end of the spring is fixedly connected to the positioning rod. An electric push rod is fixedly connected to the top of the base.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0025] Please see Figure 1-4 In this utility model: a clamping fixture for preventing deformation of thin-walled deep-drawn parts includes a base 1, a positioning rod 2 fixedly connected to the top of the base 1, a part body 3 sleeved on the positioning rod 2, the positioning rod 2 being hollow, and having annularly distributed through grooves 4 on the positioning rod 2. A clamping plate 5 is slidably connected to the inner wall of the through grooves 4, a trapezoidal block 6 is fixedly connected to one side of the clamping plate 5, the outer side of the trapezoidal block 6 is slidably connected to the inner wall of the through groove 4, a spring 7 is fixedly connected to the top of the trapezoidal block 6, and one end of the spring 7 is fixedly connected to the positioning rod 2. An electric push rod 8 is fixedly connected to the top of the part, and a drive block 9 is fixedly connected to the telescopic end of the electric push rod 8. A cylinder 10 is fixedly connected to the top of the base 1. The part body 3 is located inside the cylinder 10. A ring-shaped sliding rod 11 is inserted through the outside of the cylinder 10. A support plate 12 is fixedly connected to one end of the sliding rod 11 near the part body 3. An inclined part 13 is opened at the other end of the sliding rod 11. A drive ring 14 threadedly connected to the cylinder 10 is fitted on the cylinder 10. The shape of the clamping plate 5 and the support plate 12 on opposite sides is arc-shaped.

[0026] In this utility model, the part body 3 is a thin-walled deep-drawn part. When clamping the thin-walled deep-drawn part, the part body 3 is first put onto the positioning rod 2. Then the user rotates the drive ring 14, and the drive ring 14 will descend along the cylinder 10. During the descent of the drive ring 14, it will squeeze the inclined parts 13 on multiple slide rods 11. After the inclined parts 13 are squeezed, they will cause the slide rods 11 to shift. The slide rods 11 will drive the support plates 12 to move closer to the outside of the part body 3 until all the support plates 12 are in contact with the outside of the part body 3. At this time, the support and positioning of the part body 3 are completed.

[0027] After supporting the outer side of the part body 3, the electric push rod 8 is activated. The electric push rod 8 will drive the drive block 9 to rise. During the rise, the drive block 9 will squeeze the inclined surface of the trapezoidal block 6. After the inclined surface of the trapezoidal block 6 is squeezed, it will drive the clamping plate 5 to move closer to the inner side of the part body 3 along the inner wall of the through groove 4 until all the clamping plates 5 are in close contact with the inner wall of the part body 3, thereby completing the clamping and fixing of the part body 3. During the process, since the clamping plates 5 and the support plates 12 are set one-to-one, the part body 3 clamped by the clamping plates 5 will be supported by the support plates 12, thereby effectively reducing the deformation of the part body 3. Moreover, the clamping plates 5 are distributed in a ring on the inner side of the part body 3, further reducing the deformation of the part body 3. After the part body 3 is clamped, the part body 3 can be processed.

[0028] Please see Figure 4 The top of the drive block 9 is fitted with annularly distributed rollers 15, the outer side of the rollers 15 is rotatably connected to the drive block 9, and the outer side of the rollers 15 is in contact with the inclined surface of the trapezoidal block 6.

[0029] In this invention, the roller 15 reduces the friction between the drive block 9 and the trapezoidal block 6, thereby improving smoothness, reducing wear, and extending the service life of the device.

[0030] Please see Figure 1-3 The base 1 has an air inlet chamber 16 and an air collection chamber 17 inside. Both the air inlet chamber 16 and the air collection chamber 17 are circular. The inner wall of the air inlet chamber 16 is connected to an air inlet pipe 18. A fan 19 is installed at the left end of the air inlet pipe 18. A conduit 20 connects the air inlet chamber 16 and the air collection chamber 17. The top of the air collection chamber 17 has two sets of annularly distributed air outlet holes 21.

[0031] In this invention, after the part body 3 is placed, the user turns on the fan 19, which sends air into the air inlet chamber 16. The air then enters the air collection chamber 17 through the duct 20. As the air gathers in the air collection chamber 17, it is ejected from two sets of annularly distributed air outlets 21. The two sets of annularly distributed air outlets 21 are located on the inner and outer sides of the part body 3, respectively. After the air is ejected from the air outlets 21, it can blow off the dust on the surface of the part body 3, thereby achieving the effect of cleaning the dust on the part body 3. This effectively prevents the dust on the surface of the part body 3 from affecting the clamping and improves the practicality of the device.

[0032] Please see Figure 1-3 The inner wall of the air intake chamber 16 is equipped with multiple sets of cooling plates 22. The heat absorption end of the cooling plate 22 is located inside the air intake chamber 16, and the heat release end of the cooling plate 22 extends through and to the outside of the base 1.

[0033] In this invention, during the dust removal process, the cooling plate 22 is turned on, which reduces the temperature in the air inlet chamber 16, thereby achieving the effect of cooling the air sprayed onto the surface of the part body 3. The cooled air then reduces the temperature of the part body 3. After the temperature of the part body 3 is reduced, the strength of the part body 3 can be improved, the deformation of the part body 3 can be reduced, and the anti-deformation ability of the fixture can be further improved.

[0034] Please see Figure 1-3 The top of the positioning rod 2 is threaded with a screw 23, and the top of the screw 23 is fixedly connected to a limit plate 24.

[0035] In this invention, after the part body 3 is placed, the user can rotate the screw 23 to install it on the top of the positioning rod 2. The limiting plate 24 on the top of the screw 23 can limit the part body 3, preventing the part body 3 from flying out of the positioning rod 2 during the dust removal process, thereby improving the practicality of the device.

[0036] Please see Figure 2 Among them, a locking rod 25 threadedly connected to the drive ring 14 is inserted therethrough, and one end of the locking rod 25 is in contact with the cylinder 10.

[0037] In this utility model, after adjusting the position of the support plate 12, the user rotates the locking rod 25, which moves towards the outside of the cylinder 10 until the locking rod 25 is in close contact with the outside of the cylinder 10. Due to the friction, the position of the drive ring 14 is locked, thereby improving the stability of the support plate 12 in supporting the part body 3 and enhancing the practicality of the device.

[0038] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
