Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing equipment technology, and in particular relates to a special clamp for medical devices. Background Technology

[0002] Machine tool fixtures determine the machining accuracy of a machine tool, especially in the machining of small cutting machine tools. Currently, in the machine tool industry, insufficient fixture precision and unreasonable design lead to either inadequate precision or excessively high costs for small machine tools, making it difficult to meet the needs of workpiece machining in the medical field.

[0003] Therefore, it is necessary to overcome the shortcomings of existing technologies and design a compact and practical special fixture that can meet the requirements of low cost and high precision for machining medical machinery on special machine tools. Utility Model Content

[0004] The purpose of this utility model is to provide a special clamp for medical devices, including a pneumatic chuck for clamping workpieces, the pneumatic chuck being provided with a transmission assembly for rotating it, and the transmission assembly being provided with a drive component for driving it to operate.

[0005] The bottom of the pneumatic chuck is equipped with a clamping slide, which is slidably mounted on the guide rail on the base surface of the machine tool via a guide rail slider;

[0006] The side of the fixture slide is also fixed with a mounting base, and the special fixture can be detachably fixed to the base through the mounting base.

[0007] Furthermore, the number of special fixtures is at least two, and the multiple special fixtures have the same structural configuration. At least one special fixture is equipped with a drive unit and a transmission assembly.

[0008] Furthermore, the driving component is a motor, and the transmission assembly includes a drive wheel, a transmission belt, and a transmission wheel. The output shaft of the motor is connected to the drive wheel, the drive wheel is connected to the transmission wheel via a synchronous belt, and the transmission wheel is fixed to the outer periphery of the pneumatic chuck, driving the pneumatic chuck and the workpiece to rotate.

[0009] Furthermore, the base surface is provided with a T-slot, and the fixing seat is detachably connected to the base through the T-slot and the T-nut.

[0010] Compared with the prior art, the beneficial effects of this utility model are mainly reflected in the following aspects: the utility model can adapt to the length of most medical device processing parts by using a movable clamp, reduces machine tool costs by using a compact structure, and the multi-segment clamping of the pneumatic chuck can effectively improve the machine tool accuracy.

[0014] The following is a more detailed description of a medical device clamp according to the present invention, with reference to the schematic diagrams, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0015] like Figure 1 and 2 As shown, a medical device-specific clamp includes a machine tool base 10, with a guide rail slider 7 extending upward from the surface of the base 10. Specifically, it includes two parallel rails and a slider fixed on the rails. A clamping slide 6 is fixed to the upper surface of the slider. The clamping slide 6 is located at the bottom of a pneumatic chuck 5, which is used to clamp a workpiece 11. A driven wheel 4 is fixed to its outer periphery. The driven wheel 4 is driven by a driving wheel 2 via a synchronous belt 3. The driving wheel 2 is driven by a motor 1.

[0016] This invention uses a motor 1 to drive the drive wheel 2 to rotate, and the drive wheel 2 drives the driven wheel 4 to rotate via a conveyor belt 3. The rotation of the driven wheel 4 drives the pneumatic chuck 5 to rotate, thereby realizing the rotation of the clamped workpiece 11.

[0017] To further improve the stability of workpiece 11, we set two special fixtures on the base 10 of the machine tool and slide them on it. The two special fixtures have the same structure and can be selected to install a transmission mechanism, namely synchronous belt 3, drive wheel 2 and motor 1, depending on actual needs. However, at least one special fixture is equipped with a transmission mechanism.

[0018] The special fixture also includes a fixing seat 8, which is fixed to the upper surface of the base 10. Specifically, the upper surface of the base 10 has a recessed T-slot, and the fixing seat is detachably fixed to the upper surface of the base 10 by a T-nut 9. The fixing seat 8 is an L-shaped fixing seat, and its bottom upper surface is provided with reinforcing ribs connecting to the sides to improve the strength of the fixing seat 8.

[0019] The above are merely preferred embodiments of this utility model and do not constitute any limitation on this utility model. Any equivalent substitutions or modifications made by those skilled in the art to the technical solutions and contents disclosed in this utility model without departing from the scope of the technical solutions of this utility model shall still fall within the protection scope of this utility model.
