Description

Technical Field

[0001] The utility model relates to the technical field of clamps for machining centers, in particular to a corner cylinder clamp for large-size profiles in a machining center. Background Art

[0002] Profiles refer to solid straight bars of metal or non-metal materials that have been formed through plastic processing and have a certain cross-sectional shape and size. The cross-sectional shapes are varied, and the common ones are square, rectangular, rounded rectangle, I-shaped, hexagonal, elliptical, etc. There are also some special shapes. Different profiles are different in cross-sectional shape, size, wall thickness, etc. There are many varieties of profiles. According to the cross-sectional height, they can be divided into large steel (height ≥ 80mm), small and medium-sized steel (height < 80mm), and according to the cross-sectional shape, they can be divided into H-shaped steel, I-shaped steel, channel steel, angle steel, round steel, etc. Because profiles have high strength and rigidity and can withstand large loads, they are often used to build frames, support structures, and manufacture machine accessories, etc., and are widely used in machinery, construction, electrical appliances and other fields. Existing large-sized profiles are generally fixed by vise clamping during processing. Since large-sized profiles need to be clamped and fixed using multiple vises, the clamping time is long and the work efficiency is low. In addition, the use of vises can easily cause the surface of the profile to be deformed and damaged, affecting the processing quality. Utility Model Content

[0012] Beneficial Effects

[0013] The utility model provides a corner cylinder clamping fixture for large-size profiles in a machining center. It has the following beneficial effects:

[0014] (1) The angle cylinder clamping fixture for large-size profiles of the machining center uses multiple angle cylinders and corresponding rubber buffer blocks. The control drive system enables multiple angle cylinders to be synchronously linked, which can quickly clamp the profile body, and the pressing force of the angle cylinder on the profile body can be controlled, thereby improving the clamping efficiency. The elastic rubber buffer block is used to apply force to the profile body, which can not only increase the friction between the profile body and improve the clamping effect, but also provide a buffering effect, reduce the possibility of damage to the profile body, and improve the processing quality.

[0015] (2) The corner cylinder clamping fixture for large-size profiles of the machining center can improve the buffering effect of the rubber buffer block by providing an elastic support plate, so that the vibration received by the profile body during subsequent processing is less transmitted to the corner cylinder, thereby playing a certain protective role for the corner cylinder.

[0016] (3) The angle cylinder clamp fixture for large-size profiles of the machining center can make the rubber buffer block that has been deformed due to long-term use fit tightly to the surface of the profile body through the cooperation between the stud bolt, the first nut and the second nut, so that the device can continue to tighten and clamp, without the need to directly replace the rubber buffer block, thereby improving the durability of the device.

[0022] Embodiment 1:

[0023] like Figure 1-3 As shown, the utility model provides a corner cylinder clamp for large-size profiles in a machining center, including a workbench 1 and a corner cylinder 4, the upper surface of the workbench 1 is provided with a profile placement portion 2, the upper surface of the profile placement portion 2 is provided with a profile body 3, the bottom of the corner cylinder 4 is fixedly connected to the upper surface of the workbench 1, the output end of the corner cylinder 4 is fixedly connected with an output rotating rod 5, the top of the output rotating rod 5 is fixedly connected with a downward pressure rotating arm 6, the interior of the downward pressure rotating arm 6 is provided with a stud bolt 8, the bottom end of the stud bolt 8 is fixedly connected with a connecting plate 9, the lower surface of the connecting plate 9 is fixedly connected with an elastic support plate 12, the bottom of the elastic support plate 12 is fixedly connected with a fixing plate 13, and the lower surface of the fixing plate 13 is provided with a rubber buffer block 14.

[0024] Specifically, the corner cylinders 4 are symmetrically arranged on both sides of the profile body 3 , and the corner cylinders 4 are arranged at equal intervals along the length direction of the profile body 3 .

[0025] Specifically, an internal through hole 7 is opened inside the downward pressing rotating arm 6 , and the inner surface of the internal through hole 7 is sleeve-fitted with the outer surface of the stud bolt 8 .

[0026] Specifically, the outer surface of the stud bolt 8 is threadedly connected with a first nut 10 and a second nut 11 , and the first nut 10 and the second nut 11 are arranged on both sides of the downward pressure rotating arm 6 .

[0027] Specifically, the elastic support plate 12 is a symmetrical arc-shaped structure.

[0028] Specifically, mounting screws 15 are disposed inside the fixing plate 13 and the rubber buffer block 14 , and outer surfaces of the mounting screws 15 are threadedly connected to mounting holes inside the fixing plate 13 and the rubber buffer block 14 .

[0029] Specifically, a fixing column 16 is fixedly connected to the bottom of the inner surface of the elastic support plate 12 , and an adapting block 17 is fixedly connected to the top of the fixing column 16 . The upper surface of the adapting block 17 is pressed and adapted to the top of the inner surface of the elastic support plate 12 .

[0030] Specifically, the lower surface of the rubber buffer block 14 is extruded and fitted with the upper surface of the profile body 3 .

[0031] The working principles and beneficial effects of the above embodiments.

[0032] When in use, the angle cylinder 4 is driven to make the output rotating rod 5 extend and rotate, so that the downward pressing rotating arm 6 drives the rubber buffer block 14 to move to the surface of the profile body 3, and presses and fixes the profile body 3. The driving system is controlled to make multiple angle cylinders 4 work synchronously, so that the profile body 3 can be clamped quickly, and the pressing force of the angle cylinder 4 on the profile body 3 can be controlled, which improves the clamping efficiency. The elastic rubber buffer block 14 is used to apply a force to the profile body 3, which can not only increase the friction between the profile body 3 and the profile body 3 to improve the clamping effect, but also provide a buffering effect, reduce the possibility of damage to the profile body 3, and improve the processing quality. When the rubber buffer block 14 presses the profile body 3, the elastic support plate 12 is deformed by force until the upper surface of the adapter block 17 is against the top of the inner surface of the elastic support plate 12. The elastic force of the elastic support plate 12 can improve The buffering effect of the rubber buffer block 14 makes it possible to transmit less vibration to the corner cylinder 4 during the subsequent processing of the profile body 3, thereby providing a certain degree of protection for the corner cylinder 4. The fixed column 16 provided can prevent the elastic support plate 12 from being excessively deformed, thereby providing a supporting effect. The mounting screws 15 are embedded, which can facilitate the normal use of the rubber buffer block 14. Since the rubber buffer block 14 will be slightly deformed after being under pressure for a long time, it is easy for a small gap to form between the rubber buffer block 14 and the profile body 3, resulting in a poor clamping effect. At this time, the stud bolt 8 is adjusted to a suitable position by screwing the first nut 10 and the second nut 11, so that the rubber buffer block 14 is tightly fitted to the surface of the profile body 3, which facilitates the continued tightening and clamping of the device. There is no need to directly replace the rubber buffer block 14, thereby improving the durability of the device.
