Description

Technical Field

[0001] The utility model relates to the technical field of clamping adjustment, in particular to a flexible clamping device for machining center parts. Background Technique

[0002] A flexible clamping device is a clamping system used in a machining center or other automated equipment, and its main feature is the ability to adapt to workpieces of different shapes, sizes and materials.

[0003] Currently, the general flexible clamping device usually places the required clamping parts on the processing table and then clamps them for subsequent processing. However, the current clamping device cannot adjust the height. If a larger or heavier object is placed on the processing table, multiple personnel are needed to assist in lifting, which will cause inconvenience to the clamping work.

[0004] To solve the above problems, we propose a flexible clamping device for machining center parts. Content of the Utility Model

[0010] In the above-mentioned flexible clamping device for machining center parts, the convex plate is provided with an inclined surface. The sliding plate is located below the convex plate. The two fixed frames are located on the left and right sides of the top of the base. The electric telescopic rod is located between the two fixed frames.

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Refer to Figures 1 - 3A flexible clamping device for machining center parts includes a base 1, a placement plate 7 is provided above the base 1, two fixed frames 5 are fixedly connected to the top of the base 1, a telescopic rod 13 is slidably connected to the inner wall of the fixed frame 5, the top of the telescopic rod 13 is fixedly connected to the bottom of the placement plate 7, an electric telescopic rod 4 is fixedly connected to the top of the base 1, a fixed plate 15 is fixedly connected to the driving end of the electric telescopic rod 4, the left and right side walls of the fixed plate 15 are fixedly connected to a connecting plate 16, the outer wall of the connecting plate 16 is fixedly connected to two transmission rods 2, the top of the transmission rod 2 is fixedly connected to a slide plate 3, a sliding groove is provided on the top of the placement plate 7, and two push blocks are slidably connected in the sliding groove. 9, the outer wall of the push block 9 is fixedly provided with a convex plate 8, the fixed frame 5 is provided with a plurality of card holes 1, the telescopic rod 13 is provided with a plurality of card holes 2, the card hole 2 is connected to the card hole 1 through the card rod 14, the two transmission rods 2 are arranged on the front and rear sides of the outer side of the connecting plate 16, the transmission rod 2 is L-shaped, the outer wall of the transmission rod 2 is fixedly connected with a reinforcing rod 6, the left and right side walls of the reinforcing rod 6 are fixedly connected to the outer wall of the transmission rod 2, the convex plate 8 is provided with an inclined surface, the slide plate 3 is located below the convex plate 8, the two fixed frames 5 are located on the left and right sides of the top of the base 1, the electric telescopic rod 4 is located between the two fixed frames 5, the plurality of card holes 1 are evenly arranged on the outer side of the fixed frame 5, and the plurality of card holes 2 are evenly arranged on the outer side of the fixed frame 5. On the outside of the telescopic rod 13, the diameter of the clamping rod 14 is equal to the diameter of the plurality of clamping holes 1 and 2. Two bolts 17 are provided at the bottom of the base 1. The two bolts 17 penetrate the base 1 and are threadedly connected to the bottom of the fixed frame 5. Since the transmission rod 2 is in an L shape, the reinforcing rod 6 can increase the working stability of the transmission rod 2 and also improve the service life of the transmission rod 2. When the object is too large, the clamping rod 14 can be removed to make it detach from the clamping holes 1 and 2. In this way, the placement plate 7 will move vertically downward due to the influence of gravity and the telescopic rod 13, thereby lowering the position of the placement plate 7, making it convenient for personnel to place objects on the placement plate 7, and the bottom of the placement plate 7 is in contact with the fixed frame 5. When the object is placed, the fixing plate 15 and the connecting plate 16 are moved vertically upward by the electric telescopic rod 4. When the fixing plate 15 contacts the placement plate 7, the placement plate 7 is driven to move vertically upward. When the slide plate 3 contacts the convex plate 8, the push block 9 is driven to move inward. When the silicone sleeve 11 contacts the object, it moves into the slide groove. At this time, the fastening spring 12 is compressed and the object is clamped by the rebound performance of the fastening spring 12. When the fastening spring 12 is compressed to the limit, the object is clamped. At this time, the electric telescopic rod 4 can be stopped, and the stability of the telescopic rod 13 and the placement plate 7 can be improved by clamping the clamping rod 14 into the clamping hole 1 or the clamping hole 2.

[0023] The two shifting blocks 9 are provided with a plurality of sliding grooves. The inner side walls of the plurality of sliding grooves are fixedly connected with fastening springs 12. A plurality of clamping rods 10 are slidably connected in the plurality of sliding grooves. The plurality of sliding grooves are uniformly arranged on the outer side of the shifting block 9. A silica gel sleeve 11 is fixedly sleeved at the end of the clamping rod 10. Lubricating oil is provided at the contact part between the sliding groove and the clamping rod 10. The lubricating oil can reduce the friction between the sliding groove and the clamping rod 10. In this way, the clamping rod 10 can be more conveniently controlled to move through the fastening spring 12. If the clamping rod 10 directly contacts the object, it is very likely to leave clamping scratches or imprints on the surface of the object. The silica gel sleeve 11 can play a protective role for the object and at the same time increase the friction with the object in contact.

[0024] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
