Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as Figure 1 to Figure 5 As shown, a series of large-scale high-speed printing roller assembly hole fixtures are invented, including an underground workbench Z1, a ground workbench Z2, a self-centering device Z3, and a radial cam clamping device Z4.

[0021] Such as figure 1 , 3 As shown, the underground workbench Z1 is provided with a flat top 8.

[0022] Such as figure 1 , 3 As shown in , a self-centering device Z3 and one to two sets of radial cam clamping devices Z4 for clamping the printing roller are installed on the ground workbench Z2.

[0023] Such as figure 1 , 3 , 4, the self-centering device Z3 is composed of a coaxial double-helix linkage mechanism, left and right threaded sliders 10, 11, and a motor drive device. The motor drive device drives and connects the coaxial double-helix linkage mechanism. The double-helix scre...

Abstract

The invention provides a drill clamp universal for a large high-speed printing roller. The drill clamp comprises an underground workbench, a ground workbench, a self-centering device and diametral plane cam clamping devices. A flat tip is arranged on the underground workbench. The self-centering device and at least one set of diametral plane cam clamping device are installed on the ground workbench. The positions of the diametral plane cam clamping devices can be adjusted along a T-shaped groove in a sliding mode. The self-centering device is composed of a coaxial double-helix linkage mechanism, a left thread sliding block, a right thread sliding block and a motor driving device. The motor driving device is connected with the coaxial double-helix linkage mechanism in a driving mode. The left thread sliding block and the right thread sliding block oppositely move simultaneously along a transverse T-shaped guide rail by driving a double-helix threaded rod in the coaxial double-helix linkage mechanism and are combined with the flat tip for workpiece positioning. The drill clamp is suitable for drilling and reaming (match working) procedures of a series of assembly holes of the large high-speed printing roller, workpiece positioning is rapid and accurate, clamping is rapid, operation is easy, machining quality is guaranteed, investment is low, and cost is low.

Description

technical field [0001] The invention relates to a drilling jig for printing rollers, in particular to a universal drilling jig for large high-speed printing rollers. Background technique [0002] The large-scale high-speed printing roller is an assembly combination of left and right supports and the cylinder body. The processing of the roller assembly holes, that is, the threaded holes connecting the support and the cylinder body and the positioning pin holes, is the production bottleneck of the entire roller. According to the requirements of the roller manufacturing process, it is necessary to provide a more time-saving and labor-saving solution that meets the needs of a series of large-scale high-speed printing for the shortcomings of the cylinder body and the left and right supports, which take a long time to process the coupling holes independently, and it is difficult to ensure the coaxiality of the roller assembly assembly. Universal drill jig for rollers. The previou...
