[0002] For the processing of cylindrical thin-walled parts, traditional fixtures often clamp from the outer surface of the parts. However, this method can easily cause deformation of parts and even surface scratches, thus affecting the processing accuracy and appearance quality. Especially for some plastic products, when processed with traditional fixtures, the deformation and the problems of clamp marks and bumps on the appearance are more prominent, resulting in an increase in the defective rate. Cylindrical parts are generally fixed with an internal support clamping structure, which maintains the shape and stability of the cylindrical parts through internal support to prevent them from moving during the processing. Today's internal support clamping mechanism for cylindrical parts has poor fixing effect and poor adaptability, and cannot meet processing requirements. Utility Model Content

[0030] Internal support clamping structure for cylindrical parts, such as Figure 1-Figure 3As shown, it includes an inner support base 10 for clamping cylindrical parts, fixed support rods 20 and movable support rods 30 are symmetrically arranged on both sides of the top surface of the inner support base 10, and an adjusting cylinder 40 for adjusting the movable support rod 30 is installed on the bottom surface of the inner support base 10; a movable slide 31 is coaxially installed on the bottom surface of the movable support rod 30, and a movable slide groove 11 that is adapted to the cross-sectional size of the movable slide 31 and slidably matched is opened on the top surface of the inner support base 10; a bottom slide 42 is installed on the end of the piston rod 41 of the adjusting cylinder 40, and the bottom of the movable slide 31 is plugged and matched with the top surface of the bottom slide 42, and the two are locked by locking. The tightening bolts 43 are used to connect, and through the coordinated use of the fixed strut 20 and the movable strut 30, it can be flexibly adjusted according to tubular parts of different sizes, thereby improving the applicability of the clamping structure. The setting of the adjusting cylinder 40 allows the movable strut 30 to perform telescopic movements when needed, thereby achieving clamping of tubular parts of different lengths and improving stability; the bottom slide 42 at the end of the piston rod 41 of the adjusting cylinder 40 is plugged into and matched with the movable slide 31 at the bottom of the movable strut 30, and is connected by means of the locking bolts 43, which not only ensures the stability of the connection, but also makes the adjustment process more convenient and quick.

[0031] Furthermore, at least three groups of columns 12 are evenly and equidistantly arranged in a ring shape, which enhances the stability and load-bearing capacity of the entire clamping structure.

[0032] Specifically, the bottom of the fixed support rod 20 is plugged into the top surface of the inner support base 10, and a fixed foot 21 for fixing to the top surface of the inner support base 10 is installed at the bottom of one side of the fixed support rod 20. The cross-section between the fixed foot 21 and the fixed support rod 20 is L-shaped, and the fixed foot 21 is connected to the top surface of the inner support base 10 by at least two sets of fixing bolts 22. The L-shaped cross-section design between the fixed foot 21 and the fixed support rod 20 not only enhances the stability of the structure, but also can effectively disperse the force and avoid stress concentration.

[0033] It is worth noting that the surfaces of the fixed support rod 20 and the movable support rod 30 facing away from each other are flat or arc-shaped. Figure 1 For a plane, such as Figure 3 The arc shape enables the clamping structure to adapt to cylindrical parts of different shapes, improving the flexibility and applicability of clamping. At the same time, the flat or arc design also makes the parts fit more closely during the clamping process, improving the stability and accuracy of the clamping.

[0034] Among them, a plurality of evenly spaced anti-skid protrusions 23 are installed on the back surface of the fixed support rod 20 and the movable support rod 30. The anti-skid protrusions 23 are made of silicone material, and the height of the protrusions is 1-3mm, which can effectively increase the friction between the cylindrical parts and prevent the parts from sliding or shifting during processing. The anti-skid protrusions 23 are made of silicone material, which is soft and has good anti-skid performance. At the same time, the height of the protrusions is moderate and will not cause damage to the parts.

[0035] In addition, the width of the bottom slide 42 is greater than the width of the movable slide groove 11, and the top surface of the bottom slide 42 slides in cooperation with the bottom surface of the inner support base 10, so that the bottom slide 42 can slide stably in the movable slide groove 11, while ensuring the accuracy and stability of the sliding trajectory.

[0036] The working principle of the inner support clamping structure of the cylindrical part is as follows: the operator selects the corresponding fixed support rod 20 and movable support rod 30 according to the model of the cylindrical part, places the cylindrical part on the inner support base 10, and makes the fixed support rod 20 and movable support rod 30 located inside the cylindrical part. The cylinder 40 can be fine-tuned as needed to make the fixed support rod 20 and movable support rod 30 fit the inner wall of the cylindrical part. Figure 2 shown.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
